EXPLANATION
The Code of Federal Regulations is a codification of the general and
permanent rules published in the Federal Register by the Executive
departments and agencies of the Federal Government. The Code is divided
into 50 titles which represent broad areas subject to Federal
regulation. Each title is divided into chapters which usually bear the
name of the issuing agency. Each chapter is further subdivided into
parts covering specific regulatory areas.
Each volume of the Code is revised at least once each calendar year
and issued on a quarterly basis approximately as follows:
Title 1 through Title 16.................................as of January 1
Title 17 through Title 27..................................as of April 1
Title 28 through Title 41...................................as of July 1
Title 42 through Title 50................................as of October 1
The appropriate revision date is printed on the cover of each
volume.
LEGAL STATUS
The contents of the Federal Register are required to be judicially
noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie
evidence of the text of the original documents (44 U.S.C. 1510).
HOW TO USE THE CODE OF FEDERAL REGULATIONS
The Code of Federal Regulations is kept up to date by the individual
issues of the Federal Register. These two publications must be used
together to determine the latest version of any given rule.
To determine whether a Code volume has been amended since its
revision date (in this case, July 1, 1999), consult the ``List of CFR
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative
List of Parts Affected,'' which appears in the Reader Aids section of
the daily Federal Register. These two lists will identify the Federal
Register page number of the latest amendment of any given rule.
EFFECTIVE AND EXPIRATION DATES
Each volume of the Code contains amendments published in the Federal
Register since the last revision of that volume of the Code. Source
citations for the regulations are referred to by volume number and page
number of the Federal Register and date of publication. Publication
dates and effective dates are usually not the same and care must be
exercised by the user in determining the actual effective date. In
instances where the effective date is beyond the cut-off date for the
Code a note has been inserted to reflect the future effective date. In
those instances where a regulation published in the Federal Register
states a date certain for expiration, an appropriate note will be
inserted following the text.
OMB CONTROL NUMBERS
The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires
Federal agencies to display an OMB control number with their information
collection request.
[[Page vi]]
Many agencies have begun publishing numerous OMB control numbers as
amendments to existing regulations in the CFR. These OMB numbers are
placed as close as possible to the applicable recordkeeping or reporting
requirements.
OBSOLETE PROVISIONS
Provisions that become obsolete before the revision date stated on
the cover of each volume are not carried. Code users may find the text
of provisions in effect on a given date in the past by using the
appropriate numerical list of sections affected. For the period before
January 1, 1986, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, or 1973-1985, published in seven separate volumes. For
the period beginning January 1, 1986, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume.
INCORPORATION BY REFERENCE
What is incorporation by reference? Incorporation by reference was
established by statute and allows Federal agencies to meet the
requirement to publish regulations in the Federal Register by referring
to materials already published elsewhere. For an incorporation to be
valid, the Director of the Federal Register must approve it. The legal
effect of incorporation by reference is that the material is treated as
if it were published in full in the Federal Register (5 U.S.C. 552(a)).
This material, like any other properly issued regulation, has the force
of law.
What is a proper incorporation by reference? The Director of the
Federal Register will approve an incorporation by reference only when
the requirements of 1 CFR part 51 are met. Some of the elements on which
approval is based are:
(a) The incorporation will substantially reduce the volume of
material published in the Federal Register.
(b) The matter incorporated is in fact available to the extent
necessary to afford fairness and uniformity in the administrative
process.
(c) The incorporating document is drafted and submitted for
publication in accordance with 1 CFR part 51.
Properly approved incorporations by reference in this volume are
listed in the Finding Aids at the end of this volume.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed in
the Finding Aids of this volume as an approved incorporation by
reference, please contact the agency that issued the regulation
containing that incorporation. If, after contacting the agency, you find
the material is not available, please notify the Director of the Federal
Register, National Archives and Records Administration, Washington DC
20408, or call (202) 523-4534.
CFR INDEXES AND TABULAR GUIDES
A subject index to the Code of Federal Regulations is contained in a
separate volume, revised annually as of January 1, entitled CFR Index
and Finding Aids. This volume contains the Parallel Table of Statutory
Authorities and Agency Rules (Table I). A list of CFR titles, chapters,
and parts and an alphabetical list of agencies publishing in the CFR are
also included in this volume.
An index to the text of ``Title 3--The President'' is carried within
that volume.
The Federal Register Index is issued monthly in cumulative form.
This index is based on a consolidation of the ``Contents'' entries in
the daily Federal Register.
A List of CFR Sections Affected (LSA) is published monthly, keyed to
the revision dates of the 50 CFR titles.

Sec. 63.1211 Notification requirements.
(a) Notification of Intent To Comply (NIC). (1) All hazardous waste
combustors subject to this subpart shall prepare a Notification of
Intent to Comply that includes the following information:
(i) General information:
(A) The name and address of the owner/operator and the source;
(B) Whether the source is a major or an area source;
(C) Waste minimization and emission control technique(s) being
considered;
(D) Emission monitoring technique(s) being considered;
(E) Waste minimization and emission control technique(s)
effectiveness;
(F) A description of the evaluation criteria used or to be used to
select waste minimization and/or emission control technique(s); and
(G) A statement that the source intends to comply with this subpart
by controlling emissions from the combustion of hazardous waste pursuant
to the standards of this subpart.
(ii) Information on key activities and estimated dates for these
activities that will bring the source into compliance with emission
control requirements of this subpart. The submission of key activities
and dates is not intended to be static and may be revised by the source
during the period the NIC is in effect. Revisions shall be submitted to
the regulatory authority and be made available to the public. The
following are the key activities and dates that shall be included:
(A) The dates for beginning and completion of engineering studies to
evaluate emission control systems or process changes for emissions;
(B) The date by which contracts for emission control systems or
process changes for emission control will be awarded, or the date by
which orders will be issued for the purchase of component parts to
accomplish emission control or process changes;
(C) The date by which construction applications will be submitted;
(D) The date by which on-site construction, installation of emission
control equipment, or process change is to be initiated;
[[Page 9]]
(E) The date by which on-site construction, installation of emission
control equipment, or process change is to be completed; and
(F) The date by which final compliance is to be achieved. The
individual dates and milestones listed in paragraphs (a)(1)(ii)(A)
through (F) of this section as part of the NIC are not requirements and
therefore are not enforceable deadlines; the Agency is requiring
paragraphs (a)(1)(ii)(A) through (F) of this section as part of the NIC
only to inform the public of the source's intentions towards coming into
compliance.
(iii) A summary of the public meeting required under paragraph (b)
of this section.
(iv) For any source that does not intend to comply, but will not
stop burning hazardous waste as required under paragraph (c) of this
section, a certification that the designated source will:

Subpart FFF [Reserved]
Subpart GGG--National Emission Standards for Pharmaceuticals Production
Source: 63 FR 50326, Sept. 21, 1998, unless otherwise noted.
Sec. 63.1250 Applicability.
(a) Definition of affected source. The affected source subject to
this subpart is the pharmaceutical manufacturing operation, as defined
in Sec. 63.1251. Except as specified in paragraph (d) of this section,
the provisions of this subpart
[[Page 13]]
apply to pharmaceutical manufacturing operations that meet the criteria
specified in paragraphs (a)(1) through (a)(3) of this section as
follows:
(1) Manufacture a pharmaceutical product, as defined in
Sec. 63.1251;
(2) Are located at a plant site that is a major source as defined in
section 112(a) of the Act; and
(3) Process, use, or produce HAP.
(b) New source applicability. A new affected source subject to this
subpart and to which the requirements for new sources apply is: an
affected source for which construction or reconstruction commenced after
April 2, 1997 and the standard was applicable at the time of
construction or reconstruction; or a pharmaceutical manufacturing
process unit (PMPU), dedicated to manufacturing a single product, that
has the potential to emit 10 tons per year of any one HAP or 25 tons per
year of combined HAP, for which construction commenced after April 2,
1997.
(c) General Provisions. Table 1 of this subpart specifies the
provisions of subpart A of this part that apply to an owner or operator
of an affected source subject to this subpart, and clarifies specific
provisions in subpart A of this part as necessary for this subpart.
(d) Processes exempted from the affected source. The provisions of
this subpart do not apply to research and development facilities.
(e) Storage tank ownership determination. The owner or operator
shall follow the procedures specified in paragraphs (e)(1) through
(e)(5) of this section to determine to which PMPU a storage tank shall
belong.
(1) If a storage tank is dedicated to a single PMPU, the storage
tank shall belong to that PMPU.
(2) If a storage tank is shared among PMPU's, then the storage tank
shall belong to that PMPU located on the same plant site as the storage
tank that has the greatest annual volume input into or output from the
storage tank (i.e., said PMPU has the predominant use of the storage
tank).
(3) If predominant use cannot be determined for a storage tank that
is shared among PMPU's and if one of those PMPU's is subject to this
subpart, the storage tank shall belong to said PMPU.
(4) If the predominant use of a storage tank varies from year to
year, then predominant use shall be determined based on the utilization
that occurred during the year preceding September 21, 1998 for existing
affected sources. For new affected sources, predominant use will be
based on the first year after initial startup. The determination of
predominant use shall be reported in the Notification of Compliance
Status required by Sec. 63.1260(f). If the predominant use changes, the
redetermination of predominant use shall be reported in the next
Periodic Report.
(5) If the storage tank begins receiving material from (or sending
material to) another PMPU; or ceases to receive material from (or send
material to) a PMPU; or if the applicability of this subpart to a
storage tank has been determined according to the provisions of
paragraphs (e)(1) through (4) of this section and there is a significant
change in the use of the storage tank that could reasonably change the
predominant use, the owner or operator shall reevaluate the
applicability of this subpart to the storage tank, and report such
changes to EPA in the next Periodic report.
(f) Compliance dates. The compliance dates for affected sources are
as follows:
(1) An owner or operator of an existing affected source must comply
with the provisions of this subpart within 3 years after September 21,
1998.
(2) An owner or operator of a new or reconstructed affected source
must comply with the provisions of this subpart on September 21, 1998 or
upon startup, whichever is later.
(3) Notwithstanding the requirements of paragraphs (f)(1) and (2) of
this section, a new source which commences construction or
reconstruction after April 2, 1997 and before September 21, 1998 shall
not be required to comply with such promulgated standard until 3 years
after September 21, 1998 if:
(i) The promulgated standard is more stringent than the proposed
standard; and
(ii) The owner or operator complies with the standard as proposed
during the 3-year period immediately after September 21, 1998.
[[Page 14]]
(4) Pursuant to section 112(i)(3)(B) of the Act, an owner or
operator may request an extension allowing the existing source up to 1
additional year to comply with section 112(d) standards.
(i) For purposes of this subpart, a request for an extension shall
be submitted no later than 120 days prior to the compliance dates
specified in paragraphs (f)(1) through (3) of this section, except as
provided in paragraph (f)(4)(ii) of this section. The dates specified in
Sec. 63.6(i) for submittal of requests for extensions shall not apply to
sources subject to this subpart.
(ii) An owner or operator may submit a compliance extension request
after the date specified in paragraph (f)(4)(i) of this section provided
the need for the compliance extension arose after that date and before
the otherwise applicable compliance date, and the need arose due to
circumstances beyond reasonable control of the owner or operator. This
request shall include the data described in Sec. 63.6(i)(6)(i)(A), (B),
(C), and (D).
(g) Applicability of this subpart except during periods of startup,
shutdown, and malfunction. (1) Each provision set forth in this subpart
shall apply at all times except that emission limitations shall not
apply during periods of: startup; shutdown; and malfunction, if the
startup, shutdown, and malfunction precludes the ability of a particular
emission point of an affected source to comply with one or more specific
emission limitations to which it is subject and the owner or operator
follows the provisions for periods of startup, shutdown, and
malfunction, as specified in Secs. 63.1259(a)(3) and 63.1260(i).
Startup, shutdown, and malfunction are defined in Sec. 63.1251.
(2) The provisions set forth in Sec. 63.1255 of this subpart shall
apply at all times except during periods of nonoperation of the PMPU (or
specific portion thereof) in which the lines are drained and
depressurized resulting in the cessation of the emissions to which
Sec. 63.1255 of this subpart applies.
(3) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with the emissions
limitations of this subpart during times when emissions (or, where
applicable, wastewater streams or residuals) are being routed to such
items of equipment, if the shutdown would contravene emissions
limitations of this subpart applicable to such items of equipment. This
paragraph does not apply if the item of equipment is malfunctioning, or
if the owner or operator must shut down the equipment to avoid damage
due to a malfunction of the PMPU or portion thereof.
(4) During startups, shutdowns, and malfunctions when the emissions
limitations of this subpart do not apply pursuant to paragraphs (g)(1)
through (3) of this section, the owner or operator shall implement, to
the extent reasonably available, measures to prevent or minimize excess
emissions to the extent practical. For purposes of this paragraph,
``excess emissions'' means emissions in excess of those that would have
occurred if there were no startup, shutdown, or malfunction and the
owner or operator complied with the relevant provisions of this subpart.
The measures to be taken shall be identified in the applicable startup,
shutdown, and malfunction plan, and may include, but are not limited to,
air pollution control technologies, work practices, pollution
prevention, monitoring, and/or changes in the manner of operation of the
source. Back-up control devices are not required, but may be used if
available.
(h) Consistency with other regulations. (1) Consistency with other
MACT standards. After the compliance dates specified in this section, an
affected source subject to the provisions of this subpart that is also
subject to the provisions of any other subpart of 40 CFR part 63 may
elect, to the extent the subparts are consistent, which subpart under
which to maintain records and report to EPA. The affected source shall
identify in the Notification of Compliance Status report required by
Sec. 63.1260(f) under which authority such records will be maintained.
(2) Consistency with 40 CFR parts 264 and 265, subparts AA, BB, and/
or CC. After the compliance dates specified in this section, if any
affected source subject to this subpart is also subject to monitoring,
recordkeeping, and reporting requirements in 40 CFR part 264, subpart
AA, BB, or CC, or is subject to
[[Page 15]]
monitoring and recordkeeping requirements in 40 CFR part 265, subpart
AA, BB, or CC and the owner or operator complies with the periodic
reporting requirements under 40 CFR part 264, subpart AA, BB, or CC that
would apply to the device if the facility had final-permitted status,
the owner or operator may elect to comply either with the monitoring,
recordkeeping, and reporting requirements of this subpart, or with the
monitoring, recordkeeping, and reporting requirements in 40 CFR parts
264 and/or 265, as described in this paragraph, which shall constitute
compliance with the monitoring, record keeping, and reporting
requirements of this subpart. If the owner or operator elects to comply
with the monitoring, recordkeeping, and reporting requirements in 40 CFR
parts 264 and/or 265, the owner or operator shall report all information
required by Sec. 63.1260(g). The owner or operator shall identify in the
Notification of Compliance Status required by Sec. 63.1260(f) the
monitoring, recordkeeping, and reporting authority under which the owner
or operator will comply.
(3) Consistency with 40 CFR 60.112b. After the compliance dates
specified in this section, a storage tank controlled with a floating
roof and in compliance with the provisions of 40 CFR 60.112b, subpart
Kb, constitutes compliance with the provisions of this subpart GGG. A
storage tank with a fixed roof, closed vent system, and control device
in compliance with the provisions of 40 CFR 60.112b, subpart Kb must
comply with the monitoring, recordkeeping, and reporting provisions of
this subpart GGG. The owner or operator shall identify in the
Notification of Compliance Status report required by Sec. 63.1260(f)
which tanks are in compliance with subpart Kb.
(4) Consistency with subpart I of this part. After the compliance
dates specified in this section, for equipment at an affected source
subject to this subpart that is also subject to subpart I of this part,
an owner or operator may elect to comply with either the provisions of
this subpart GGG or the provisions of subpart I of this part. The owner
or operator shall identify in the Notification of Compliance Status
report required by Sec. 63.1260(f) the provisions with which the owner
elects to comply.
(5) Consistency with other regulations for wastewater. After the
compliance dates specified in this section, the owner or operator of an
affected wastewater that is also subject to provisions in 40 CFR parts
260 through 272 shall comply with the more stringent control
requirements (e.g., waste management units, numerical treatment
standards, etc.) and the more stringent testing, monitoring, recording,
and recordkeeping requirements that overlap between the provisions of
this subpart and the provisions of 40 CFR parts 260 through 272. The
owner or operator shall keep a record of the information used to
determine which requirements were the most stringent and shall submit
this information if requested by the Administrator.
(i) For the purposes of establishing whether a person is in
violation of this subpart, nothing in this subpart shall preclude the
use of any credible evidence or information relevant to whether a source
would have been in compliance with applicable requirements.
Sec. 63.1251 Definitions.
Terms used in this subpart are defined in the Act, in subpart A of
this part, or in this section. If the same term is defined in subpart A
of this part and in this section, it shall have the meaning given in
this section for the purposes of this subpart.
Active ingredient means any component that is intended to furnish
pharmacological activity or other direct effect in the diagnosis, cure,
mitigation, treatment, or prevention of disease, or to affect the
structure or any function of the body of man or other animals. The term
includes those components that may undergo chemical change in the
manufacture of the pharmaceutical product and be present in the
pharmaceutical product in a modified form intended to furnish the
specified activity or effect.
Actual HAP emissions means the HAP emitted to the atmosphere from
either uncontrolled or controlled emission points.
[[Page 16]]
Air pollution control device or Control device means equipment
installed on a process vent, storage tank, wastewater treatment exhaust
stack, or combination thereof that reduces the mass of HAP emitted to
the air. The equipment may consist of an individual device or a series
of devices. Examples include, but are not limited to, incinerators,
carbon adsorption units, condensers, flares, boilers, process heaters,
and gas absorbers. Process condensers are not considered air pollution
control devices or control devices.
Annual average concentration, as used in the wastewater provisions,
means the annual average concentration as determined according to the
procedures specified in Sec. 63.1257(e)(1).
Automated monitoring and recording system means any means of
measuring values of monitored parameters and creating a hard copy or
computer record of the measured values that does not require manual
reading of monitoring instruments and manual transcription of data
values. Automated monitoring and recording systems include, but are not
limited to, computerized systems and strip charts.
Batch emission episode means a discrete venting episode that may be
associated with a single unit operation. A unit operation may have more
than one batch emission episode. For example, a displacement of vapor
resulting from the charging of a vessel with HAP will result in a
discrete emission episode that will last through the duration of the
charge and will have an average flowrate equal to the rate of the
charge. If the vessel is then heated, there will also be another
discrete emission episode resulting from the expulsion of expanded
vapor. Both emission episodes may occur in the same vessel or unit
operation. There are possibly other emission episodes that may occur
from the vessel or other process equipment, depending on process
operations.
Batch operation or Batch process means a noncontinuous operation
involving intermittent or discontinuous feed into equipment, and, in
general, involves the emptying of the equipment after the batch
operation ceases and prior to beginning a new operation. Addition of raw
material and withdrawal of product do not occur simultaneously in a
batch operation.
Bench-scale batch process means a batch process (other than a
research and development facility) that is capable of being located on a
laboratory bench top. This bench-scale equipment will typically include
reagent feed vessels, a small reactor and associated product separator,
recovery and holding equipment. These processes are only capable of
producing small quantities of product.
Block means a time period that comprises a single batch.
Cleaning operation means routine rinsing, washing, or boil-off of
equipment in batch operations between batches.
Closed biological treatment process means a tank or surface
impoundment where biological treatment occurs and air emissions from the
treatment process are routed to either a control device by means of a
closed-vent system or by means of hard-piping. The tank or surface
impoundment has a fixed roof, as defined in this section, or a floating
flexible membrane cover that meets the requirements specified in
Sec. 63.1256(c).
Closed-loop system means an enclosed system that returns process
fluid to the process and is not vented to the atmosphere except through
a closed-vent system.
Closed-purge system means a system or combination of system and
portable containers, to capture purged liquids. Containers must be
covered or closed when not being filled or emptied.
Closed-vent system means a system that is not open to the atmosphere
and is composed of piping, ductwork, connections, and, if necessary,
flow inducing devices that transport gas or vapor from an emission point
to a control device.
Combustion device means an individual unit of equipment, such as a
flare, incinerator, process heater, or boiler, used for the combustion
of HAP vapors.
Component means any ingredient for use in the manufacture of a drug
product, including those that may not appear in such drug product.
Connector means flanged, screwed, or other joined fittings used to
connect
[[Page 17]]
two pipe lines or a pipe line and a piece of equipment. A common
connector is a flange. Joined fittings welded completely around the
circumference of the interface are not considered connectors for the
purpose of this regulation. For the purpose of reporting and
recordkeeping, connector means joined fittings that are not
inaccessible, ceramic, or ceramic-lined as described in
Sec. 63.1255(b)(1)(vii) and Sec. 63.1255(f)(3).
Construction means the onsite fabrication, erection, or installation
of an affected source or a PMPU.
Consumption means the quantity of HAP entering a process that is not
used as reactant (makeup). If the same HAP component is generated in the
process as well as added as makeup, consumption shall include the
quantity generated in the process, as calculated assuming 100
theoretical conversion. The quantity of material used as reactant is the
theoretical amount needed assuming a 100 percent stoichiometric
conversion. Makeup is the net amount of material that must be added to
the process to replenish losses.
Container, as used in the wastewater provisions, means any portable
waste management unit that has a capacity greater than or equal to 0.1
m3 in which a material is stored, transported, treated, or
otherwise handled. Examples of containers are drums, barrels, tank
trucks, barges, dumpsters, tank cars, dump trucks, and ships.
Continuous process means a process where the inputs and outputs flow
continuously throughout the duration of the process. Continuous
processes are typically steady state.
Continuous recorder means a data recording device that either
records an instantaneous data value at least once every 15 minutes or
records 15-minute or more frequent block average values.
Continuous seal means a seal that forms a continuous closure that
completely covers the space between the wall of the storage tank and the
edge of the floating roof. A continuous seal may be a vapor-mounted,
liquid-mounted, or metallic shoe seal.
Control device, for purposes of this Sec. 63.1255, means any
equipment used for recovering or oxidizing organic hazardous air
pollutant vapors. Such equipment includes, but is not limited to,
absorbers, carbon adsorbers, condensers, flares, boilers, and process
heaters.

but not necessarily, in association with inactive ingredients; or
(4) Any component whose intended primary use is to furnish
pharmacological activity or other direct effect in the diagnosis, cure,
mitigation, treatment, or prevention of disease, or to affect the
structure or any function of the body of man or other animals (the term
does not include excipients, but includes drug components such as raw
starting materials or precursors that undergo chemical change or
processing before they become active ingredients).
Plant site means all contiguous or adjoining property that is under
common control, including properties that are separated only by a road
or other public right-of-way. Common control includes properties that
are owned, leased, or operated by the same entity, parent entity,
subsidiary, or any combination thereof.
Point of determination (POD) means the point where a wastewater
stream exits the process, storage tank, or last recovery device. If
soluble and/or partially soluble HAP compounds are not recovered from
water before discharge, the discharge point from the process equipment
or storage tank is a POD. If water streams are routed to a recovery
device, the discharge from the recovery device is a POD. There can be
more than 1 POD per process or PMPU.
Pressure release means the emission of materials resulting from the
system pressure being greater than the set pressure of the pressure
relief device. This release can be one release or a series of releases
over a short time period due to a malfunction in the process.
Pressure relief device or valve means a safety device used to
prevent operating pressures from exceeding the maximum allowable working
pressure of the process equipment. A common pressure relief device is a
spring-loaded pressure relief valve. Devices that are actuated either by
a pressure of less than or equal to 2.5 psig or by a vacuum are not
pressure relief devices.
Primary use means the single largest use of a material.
Process means all equipment which collectively function to produce a
pharmaceutical product. A process may consist of one or more unit
operations. For the purposes of this subpart, process includes all or a
combination of reaction, recovery, separation, purification, or other
activity, operation, manufacture, or treatment which are used to produce
a pharmaceutical product. Cleaning operations conducted are considered
part of the process. The holding of the pharmaceutical product in tanks
or other holding equipment for more than 30 consecutive days, or
transfer of the pharmaceutical product to containers for shipment, marks
the end of a process, and the tanks are considered part of the PMPU that
produced the stored material. When material from one unit operation is
used as the feedstock for the production of two or more different
pharmaceutical products, the unit operation is considered the endpoint
of the process that produced the material, and the unit operations into
which the material is routed mark the beginning of the other processes.
Nondedicated recovery devices located within a contiguous area within
the affected source are considered single processes. Nondedicated
formulation operations occurring within a contiguous area are considered
a single process that is used to formulate numerous materials and/or
products. Quality Assurance and Quality Control laboratories are not
considered part of any process.
[[Page 22]]
Process condenser means a condenser whose primary purpose is to
recover material as an integral part of a process. The condenser must
support a vapor-to-liquid phase change for periods of source equipment
operation that are at or above the boiling or bubble point of
substance(s) at the liquid surface. Examples of process condensers
include distillation condensers, reflux condensers, and condensers used
in stripping or flashing operations. In a series of condensers, all
condensers up to and including the first condenser with an exit gas
temperature below the boiling or bubble point of the substance(s) at the
liquid surface are considered to be process condensers. All condensers
in line prior to a vacuum source are included in this definition.
Process shutdown means a work practice or operational procedure that
stops production from a process or part of a process during which it is
technically feasible to clear process material from a process or part of
a process consistent with safety constraints and during which repairs
can be effected. An unscheduled work practice or operational procedure
that stops production from a process or part of a process for less than
24 hours is not a process shutdown. An unscheduled work practice or
operational procedure that would stop production from a process or part
of a process for a shorter period of time than would be required to
clear the process or part of the process of materials and start up the
process, and would result in greater emissions than delay of repair of
leaking components until the next scheduled process shutdown, is not a
process shutdown. The use of spare equipment and technically feasible
bypassing of equipment without stopping production are not process
shutdowns.
Process tank means a tank that is used to collect material
discharged from a feedstock storage tank or unit operation within the
process and transfer this material to another unit operation within the
process or to a product storage tank. Surge control vessels and bottoms
receivers that fit these conditions are considered process tanks.
Process vent means a vent from a unit operation or vents from
multiple unit operations within a process that are manifolded together
into a common header, through which a HAP-containing gas stream is, or
has the potential to be, released to the atmosphere. Examples of process
vents include, but are not limited to, vents on condensers used for
product recovery, bottom receivers, surge control vessels, reactors,
filters, centrifuges, and process tanks. Emission streams that are
undiluted and uncontrolled containing less than 50 ppmv HAP, as
determined through process knowledge that no HAP are present in the
emission stream or using an engineering assessment as discussed in
Sec. 63.1257(d)(2)(ii), test data using Methods 18 of 40 CFR part 60,
appendix A, or any other test method that has been validated according
to the procedures in Method 301 of appendix A of this part, are not
considered process vents. Process vents do not include vents on storage
tanks regulated under Sec. 63.1253, vents on wastewater emission sources
regulated under Sec. 63.1256, or pieces of equipment regulated under
Sec. 63.1255.
Production-indexed HAP consumption factor is the result of dividing
the annual consumption of total HAP by the annual production rate, per
process.
Production-indexed volatile organic compound (VOC) consumption
factor is the result of dividing the annual consumption of total VOC by
the annual production rate, per process.

used in the storage, treatment, recycling, and reclamation of municipal
sewage or industrial wastes of a liquid nature as defined in section
212(2)(A) of the Clean Water Act, as amended [33 U.S.C.
Sec. 1292(2)(A)]. A POTW includes the treatment works, intercepting
sewers, outfall sewers, sewage collection systems, pumping, power, and
other equipment. The POTW is defined at 40 CFR 403.3(o).

individual
[[Page 23]]
unit of equipment used for the purpose of recovering chemicals for fuel
value (i.e., net positive heating value), use, reuse, or for sale for
fuel value, use or reuse. Examples of equipment that may be recovery
devices include organic removal devices such as decanters, strippers, or
thin-film evaporation units. To be a recovery device, a decanter and any
other equipment based on the operating principle of gravity separation
must receive only two-phase liquid streams.
Repaired means that equipment is adjusted, or otherwise altered, to
eliminate a leak as defined in the applicable sections of Sec. 63.1255.
Research and development facility means any stationary source whose
primary purpose is to conduct research and development into new

manufacture of products for commercial sale in commerce, except in a de
minimis manner.
Residual means any HAP-containing liquid or solid material that is
removed from a wastewater stream by a waste management unit or treatment
process that does not destroy organics (nondestructive unit). Examples
of residuals from nondestructive waste management units are: the organic
layer and bottom residue removed by a decanter or organic-water
separator and the overheads from a steam stripper or air stripper.
Examples of materials which are not residuals are: silt; mud; leaves;
bottoms from a steam stripper or air stripper; and sludges, ash, or
other materials removed from wastewater being treated by destructive
devices such as biological treatment units and incinerators.
Safety device means a closure device such as a pressure relief

functions exclusively to prevent physical damage or permanent
deformation to a unit or its air emission control equipment by venting
gases or vapors directly to the atmosphere during unsafe conditions
resulting from an unplanned, accidental, or emergency event. For the
purposes of this subpart, a safety device is not used for routine
venting of gases or vapors from the vapor headspace underneath a cover
such as during filling of the unit or to adjust the pressure in this
vapor headspace in response to normal daily diurnal ambient temperature
fluctuations. A safety device is designed to remain in a closed position
during normal operations and open only when the internal pressure, or
another relevant parameter, exceeds the device threshold setting
applicable to the air emission control equipment as determined by the
owner or operator based on manufacturer recommendations, applicable
regulations, fire protection and prevention codes, standard engineering
codes and practices, or other requirements for the safe handling of
flammable, combustible, explosive, reactive, or hazardous materials.
Sampling connection system means an assembly of equipment within a
process unit used during periods of representative operation to take
samples of the process fluid. Equipment used to take nonroutine grab
samples is not considered a sampling connection system.
Sensor means a device that measures a physical quantity or the
change in a physical quantity, such as temperature, pressure, flow rate,
pH, or liquid level.
Set pressure means the pressure at which a properly operating
pressure relief device begins to open to relieve atypical process system
operating pressure.
Sewer line means a lateral, trunk line, branch line, or other
conduit including, but not limited to, grates, trenches, etc., used to
convey wastewater streams or residuals to a downstream waste management
unit.
Shutdown means the cessation of operation of a PMPU or an individual
piece of equipment required or used to comply with this part or for
emptying and degassing storage tanks. Shutdown occurs for purposes
including but not limited to: periodic maintenance, replacement of
equipment, or repair. Shutdown does not apply to routine batch
operations or the rinsing or washing of equipment in batch operations
between batches.
Single-seal system means a floating roof having one continuous seal
that completely covers the space between
[[Page 24]]
the wall of the storage tank and the edge of the floating roof. This
seal may be a vapor-mounted, liquid-mounted, or metallic shoe seal.

vents with total emissions of less than 10 tons of HAP per year, before
control.
Soluble HAP means a HAP listed in Table 3 of this subpart.
Startup means the first time a new or reconstructed source begins
production, or, for new equipment added, including equipment used to
comply with this subpart, the first time the equipment is put into
operation, or for the introduction of a new product/process, the first
time the product or process is run in equipment. As used in
Sec. 63.1255, startup means the setting in operation of a piece of
equipment or a control device that is subject to this subpart.
Storage tank means a tank or other vessel that is used to store
organic liquids that contain one or more HAP as feedstocks or products
of a PMPU. The following are not considered storage tanks for the
purposes of this subpart:

railcars, barges, or ships;
(2) Pressure vessels designed to operate in excess of 204.9
kilopascals and without emissions to the atmosphere;
(3) Vessels storing organic liquids that contain HAP only as
impurities;
(4) Wastewater storage tanks; and
(5) Process tanks.
Surface impoundment means a waste management unit which is a natural
topographic depression, manmade excavation, or diked area formed
primarily of earthen materials (although it may be lined with manmade
materials), which is designed to hold an accumulation of liquid wastes
or waste containing free liquids. A surface impoundment is used for the
purpose of treating, storing, or disposing of wastewater or residuals,
and is not an injection well. Examples of surface impoundments are
equalization, settling, and aeration pits, ponds, and lagoons.
Total organic compounds (TOC) means those compounds measured
according to the procedures of Method 18 or Method 25A, 40 CFR part 60,
appendix A.
Treatment process means a specific technique that removes or
destroys the organics in a wastewater or residual stream such as a steam
stripping unit, thin-film evaporation unit, waste incinerator,
biological treatment unit, or any other process applied to wastewater
streams or residuals to comply with Sec. 63.1256. Most treatment
processes are conducted in tanks. Treatment processes are a subset of
waste management units.
Uncontrolled HAP emissions means a gas stream containing HAP which
has exited the process (or process condenser, if any), but which has not
yet been introduced into an air pollution control device to reduce the
mass of HAP in the stream. If the process vent is not routed to an air
pollution control device, uncontrolled emissions are those HAP emissions
released to the atmosphere.
Unit operation means those processing steps that occur within
distinct equipment that are used, among other things, to prepare
reactants, facilitate reactions, separate and purify products, and
recycle materials. Equipment used for these purposes includes but is not
limited to reactors, distillation columns, extraction columns,
absorbers, decanters, dryers, condensers, and filtration equipment.
Vapor-mounted seal means a continuous seal that completely covers
the annular space between the wall, the storage tank or waste management

tanks, air flotation units, surface impoundments, containers, oil-water
or organic-water separators, individual drain systems, biological
wastewater treatment units, waste incinerators, and organic removal
devices such as steam and air stripper units, and thin film evaporation
units. If such equipment is used
[[Page 25]]
for recovery then it is part of a pharmaceutical process and is not a
waste management unit.
Wastewater means any portion of an individual wastewater stream or
any aggregation of wastewater streams.
Wastewater stream means water that is discarded from a PMPU through
a single POD, that contains an annual average concentration of partially
soluble and/or soluble HAP compounds of at least 5 parts per million by
weight and a load of at least 0.05 kg/yr, and that is not exempted by
the provisions of Sec. 63.1256(a)(3). For the purposes of this subpart,
noncontact cooling water is not considered a wastewater stream.
Wastewater streams are generated by both process operations and
maintenance activities.
Wastewater tank means a stationary waste management unit that is
designed to contain an accumulation of wastewater or residuals and is
constructed primarily of nonearthen materials (e.g., wood, concrete,
steel, plastic) which provide structural support. Wastewater tanks used
for flow equalization are included in this definition.
Water seal controls means a seal pot, p-leg trap, or other type of
trap filled with water (e.g., flooded sewers that maintain water levels
adequate to prevent air flow through the system) that creates a water
barrier between the sewer line and the atmosphere. The water level of
the seal must be maintained in the vertical leg of a drain in order to
be considered a water seal.

Sec. 63.1257(g) or (h) for any storage tank or process.
(1) A State may prohibit averaging of HAP emissions and require the
owner or operator of an existing source to comply with the provisions in
Secs. 63.1253 and 63.1254.
(2) Only emission sources subject to the requirements of
Sec. 63.1253(b)(1) and (c)(1) or Sec. 63.1254(a)(2), (a)(3)(ii)(A) or
(a)(3)(iii) may be included in any averaging group.
(3) Processes which have been permanently shutdown or storage tanks
permanently taken out of HAP service may not be included in any
averaging group.
(4) Processes and storage tanks already controlled on or before
November 15, 1990 may not be included in an emissions averaging group,
except where the level of control is increased after November 15, 1990.
In these cases, the uncontrolled emissions shall be the controlled
emissions as calculated on November 15, 1990 for the purpose of
determining the uncontrolled emissions as specified in Sec. 63.1257(g)
and (h).
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart may not be included in an emission
averaging group, unless the level of control has been increased after
November 15, 1990 above what is required by the other State or Federal
rule. Only the control above what is required by the other State or
Federal rule will be credited. However, if an emission point has been
used to generate emissions averaging credit in an approved emissions
average, and the point is subsequently made subject to a State or
Federal rule other than this subpart, the point can continue to generate
emissions averaging credit for the purpose of complying with the
previously approved average.
(6) Not more than 20 processes subject to Sec. 63.1254(a)(2)(i), 20
storage tanks subject to Sec. 63.1253(b)(1), and 20 storage tanks
subject to Sec. 63.1253(c)(1)(i) at an affected source may be included
in an emissions averaging group.
(7) Compliance with the emissions standards in Sec. 63.1253 shall be
satisfied when the annual percent reduction efficiency is greater than
or equal to 90 percent for those tanks meeting the requirements of
Sec. 63.1253(a)(1) and 95 percent for those tanks meeting the
requirements of Sec. 63.1253(a)(2), as demonstrated using the test

shall be satisfied when the annual percent reduction efficiency is
greater than or equal to 93 percent, as demonstrated using the test
methods and compliance procedures specified in Sec. 63.1257(h).
(e) Pollution prevention alternative. Except as provided in
paragraph (e)(1) of this section, owners and operators may choose to
meet the pollution prevention alternative requirement specified in
either paragraph (e)(2) or (3) of this section for any PMPU, in lieu of
the requirements specified in Secs. 63.1253, 63.1254, 63.1255, and
63.1256. Compliance with paragraphs (e)(2) and (3) of this section shall
be demonstrated through the procedures in Sec. 63.1257(f).
(1) The HAP that are generated in the PMPU that are not part of the
production-indexed consumption factor must be controlled according to
the requirements of Secs. 63.1253, 63.1254, 63.1255, and 63.1256. The
HAP that are generated as a result of combustion control of emissions
must be controlled according to the requirements of paragraph (g) of
this section.
(2) The production-indexed HAP consumption factor (kg HAP consumed/
kg produced) shall be reduced by at least 75 percent from a 3 year
average baseline established no earlier than the 1987 calendar year, or
for the time period from startup of the process until the present in
which the PMPU was operational and data are available, whichever is the
lesser time period. If a time period less than 3 years is used to set
the baseline, the data must represent at least 1 year's worth of data.
For any reduction in the HAP factor achieved by reducing a HAP that is
also a VOC, an equivalent reduction in the VOC factor is also required.
For any reduction in the HAP factor that is achieved
[[Page 27]]
by reducing a HAP that is not a VOC, the VOC factor may not be
increased.
(3) Both requirements specified in paragraphs (e)(3)(i) and (ii) of
this section are met.
(i) The production-indexed HAP consumption factor (kg HAP consumed/
kg produced) shall be reduced by at least 50 percent from a 3-year
average baseline established no earlier than the 1987 calendar year, or
for the time period from startup of the process until the present in
which the PMPU was operational and data are available, whichever is
less. If a time period less than 3 years is used to set the baseline,
the data must represent at least 1 year's worth of data. For any
reduction in the HAP factor achieved by reducing a HAP that is also a
VOC, an equivalent reduction in the VOC factor is also required. For any
reduction in the HAP factor that is achieved by reducing a HAP that is
not a VOC, the VOC factor may not be increased.
(ii) The total PMPU HAP emissions shall be reduced by an amount, in
kg/yr, that, when divided by the annual production rate, in kg/yr, and
added to the reduction of the production-indexed HAP consumption factor,
in kg/kg, yields a value of at least 75 percent of the average baseline
HAP production-indexed consumption factor established according to
paragraph (e)(3)(i) of this section according to the equation provided
in Sec. 63.1257(f)(2)(ii)(A). The total PMPU VOC emissions shall be
reduced by an amount calculated according to the equation provided in
Sec. 63.1257(f)(2)(ii)(B). The annual reduction in HAP and VOC air
emissions must be due to the use of the following control devices:
(A) Combustion control devices such as incinerators, flares or
process heaters.
(B) Control devices such as condensers and carbon adsorbers whose
recovered product is destroyed or shipped offsite for destruction.
(C) Any control device that does not ultimately allow for recycling
of material back to the PMPU.
(D) Any control device for which the owner or operator can
demonstrate that the use of the device in controlling HAP emissions will
have no effect on the production-indexed consumption factor for the
PMPU.
(f) Control requirements for certain liquid streams in open systems
within a PMPU. (1) The owner or operator shall comply with the
provisions of Table 5 of this subpart, for each item of equipment
meeting all the criteria specified in paragraphs (f)(2) through (4) and
either paragraph (f)(5)(i) or (ii) of this section.
(2) The item of equipment is of a type identified in Table 5 of this
subpart;
(3) The item of equipment is part of a PMPU, as defined in
Sec. 63.1251;
(4) The item of equipment is controlled less stringently than in
Table 5 of this subpart and the item of equipment is not otherwise
exempt from controls by the provisions of this subpart or subpart A of
this part; and
(5) The item of equipment:
(i) Is a drain, drain hub, manhole, lift station, trench, pipe, or
oil/water separator that conveys water with an annual average
concentration greater than or equal to 1,300 parts per million by weight
(ppmw) of partially soluble HAP compounds; or an annual average
concentration greater than or equal to 5,200 ppmw of partially soluble
and/or soluble HAP compounds. The annual average concentration shall be
determined according to the procedures in Sec. 63.1257(e)(1)(ii).
(ii) Is a tank that receives one or more streams that contain water
with an annual average concentration greater than or equal to 1,300 ppmw
of partially soluble HAP compounds, or greater than or equal to 5,200

or operator of the source shall determine the average concentration of
the stream at the inlet to the tank and according to the procedures in
Sec. 63.1257(e)(1)(ii).
(g) Control requirements for halogenated vent streams that are
controlled by combustion devices. If a combustion device is used to
comply with the provisions of Secs. 63.1253 (storage tanks), 63.1254
(process vents), 63.1256(h) (wastewater vent streams) for a halogenated
vent stream, then the vent stream shall be ducted to a halogen reduction
device such as, but not limited to, a scrubber, before it is discharged
[[Page 28]]
to the atmosphere. The halogen reduction device must reduce emissions by
the amounts specified in either paragraph (g)(1) or (2) of this section.
(1) A halogen reduction device after the combustion control device
must reduce overall emissions of hydrogen halides and halogens, as
defined in Sec. 63.1251, by 95 percent or to a concentration less than

(6) The provisions of this section do not apply to bench-scale
processes, regardless of whether the processes are located at the same
plant site as a process subject to the provisions of this subpart.
(7) Each piece of equipment to which this section applies shall be
identified such that it can be distinguished readily from equipment that
is not subject to this section. Identification of the equipment does not
require physical tagging of the equipment. For example, the equipment
may be identified on a plant site plan, in log entries, or by
designation of process boundaries by some form of weatherproof
identification. If changes are made to the affected source subject to
the leak detection requirements, equipment identification for each type
of component shall be updated, if needed, within 15 calendar days of the
end of each monitoring period for that component.

the 4 years specified in paragraph (b)(1)(vii)(C) of this section or the
first 4 years specified in Sec. 63.174(b)(3)(iii). At the end of that 2
year monitoring period, the owner or operator shall monitor once per
year while the percent leaking connectors is greater than or equal to
0.5 percent; if the percent leaking connectors is less than 0.5 percent,
the owner or operator may return to monitoring once every 4 years or may
monitor in accordance with Sec. 63.174(b)(3)(iii), if appropriate.
(E) Section 63.174(b)(3)(v) shall not apply. Instead, if an owner or
operator complying with the requirements of paragraph (b)(1)(vii)(C) and
(D) of this section or Sec. 63.174 (b)(3)(iii) for a group of processes
determines that 1 percent or greater of the connectors are leaking, the
owner or operator shall increase the monitoring frequency to one time
per year. The owner or operator may again elect to use the provisions of

operator shall monitor valves for leaks at the intervals specified
below:
(i) For a group of processes with 2 percent or greater leaking
valves, calculated according to paragraph (e)(6) of this section, the
owner or operator shall monitor each valve once per month, except as
specified in paragraph (e)(9) of this section.
(ii) For a group of processes with less than 2 percent leaking

2 quarters.
(iv) For a group of processes with less than 0.5 percent leaking
valves, the owner or operator may elect to monitor each valve once every
4 quarters.
(v) For a group of processes with less than 0.25 percent leaking
valves, the owner or operator may elect to monitor each valve once every
2 years.
(5) Calculation of percent leakers. For a group of processes to
which this subpart applies, an owner or operator may choose to subdivide
the valves in the applicable group of processes and apply the provisions
of paragraph (e)(4) of this section to each subgroup. If the owner or
operator elects to subdivide the valves in the applicable group of
processes, then the provisions of paragraphs (e)(5)(i) through
(e)(5)(viii) of this section apply.
(i) The overall performance of total valves in the applicable group
of processes must be less than 2 percent leaking valves, as detected
according to paragraphs (e)(3) (i) and (ii) of this section and as
calculated according to
[[Page 36]]
paragraphs (e)(6) (ii) and (iii) of this section.
(ii) The initial assignment or subsequent reassignment of valves to
subgroups shall be governed by the provisions of paragraphs (e)(5)(ii)
(A) through (C) of this section.
(A) The owner or operator shall determine which valves are assigned
to each subgroup. Valves with less than 1 year of monitoring data or
valves not monitored within the last 12 months must be placed initially
into the most frequently monitored subgroup until at least 1 year of
monitoring data has been obtained.
(B) Any valve or group of valves can be reassigned from a less
frequently monitored subgroup to a more frequently monitored subgroup
provided that the valves to be reassigned were monitored during the most
recent monitoring period for the less frequently monitored subgroup. The
monitoring results must be included with the less frequently monitored
subgroup's monitoring event and associated next percent leaking valves
calculation for that group.
(C) Any valve or group of valves can be reassigned from a more
frequently monitored subgroup to a less frequently monitored subgroup
provided that the valves to be reassigned have not leaked for the period
of the less frequently monitored subgroup (e.g., for the last 12 months,
if the valve or group of valves is to be reassigned to a subgroup being
monitored annually). Nonrepairable valves may not be reassigned to a
less frequently monitored subgroup.
(iii) The owner or operator shall determine every 6 months if the
overall performance of total valves in the applicable group of processes
is less than 2 percent leaking valves and so indicate the performance in
the next periodic report. If the overall performance of total valves in
the applicable group of processes is 2 percent leaking valves or
greater, the owner or operator shall revert to the program required in
paragraphs (e)(2) through (e)(4) of this section. The overall
performance of total valves in the applicable group of processes shall
be calculated as a weighted average of the percent leaking valves of
each subgroup according to the following Equation 4:
[GRAPHIC] [TIFF OMITTED] TR21SE98.002
where:
%VLO = overall performance of total valves in the applicable
process or group of processes
%VLi = percent leaking valves in subgroup I, most recent
value calculated according to the procedures in paragraphs (e)(6) (ii)
and (iii) of this section
Vi = number of valves in subgroup I
n = number of subgroups
(iv) Records. In addition to records required by paragraph (g) of
this section, the owner or operator shall maintain records specified in
paragraphs (e)(5)(iv)(A) through (D) of this section.

(B) Monitoring results and calculations made for each subgroup for
each monitoring period,
(C) Which valves are reassigned and when they were reassigned, and
(D) The results of the semiannual overall performance calculation
required in paragraph (e)(5)(iii) of this section.
(v) The owner or operator shall notify the Administrator no later
than 30 days prior to the beginning of the next monitoring period of the
decision to subgroup valves. The notification shall identify the
participating processes and the valves assigned to each subgroup.
(vi) Semiannual reports. In addition to the information required by
paragraph (h)(3) of this section, the owner or operator shall submit in
the periodic reports the information specified in paragraphs
(e)(5)(vi)(A) and (B) of this section.
(A) Valve reassignments occurring during the reporting period, and
(B) Results of the semiannual overall performance calculation
required by paragraph (e)(5)(iii) of this section.
[[Page 37]]
(vii) To determine the monitoring frequency for each subgroup, the
calculation procedures of paragraph (e)(6)(iii) of this section shall be
used.
(viii) Except for the overall performance calculations required by
paragraphs (e)(5)(i) and (e)(5)(iii) of this section, each subgroup
shall be treated as if it were a process for the purposes of applying
the provisions of this section.
(6)(i) The owner or operator shall decide no later than the
implementation date of this subpart or upon revision of an operating
permit how to group the processes. Once the owner or operator has
decided, all subsequent percentage calculations shall be made on the
same basis.
(ii) Percent leaking valves for each group of processes or subgroup
shall be determined by the following Equation 5:
%VL = [VL/VT] x 100 (Eq. 5)
Where:
%VL = percent leaking valves
VL = number of valves found leaking excluding nonrepairables
as provided in paragraph (e)(6)(iv)(A) of this section
VT = total valves monitored, in a monitoring period excluding
valves monitored as required by (e)(7)(iii) of this section
(iii) When determining monitoring frequency for each group of
processes or subgroup subject to monthly, quarterly, or semiannual
monitoring frequencies, the percent leaking valves shall be the
arithmetic average of the percent leaking valves from the last two
monitoring periods. When determining monitoring frequency for each group
of processes or subgroup subject to annual or biennial (once every 2
years) monitoring frequencies, the percent leaking valves shall be the
arithmetic average of the percent leaking valves from the last three
monitoring periods.
(iv)(A) Nonrepairable valves shall be included in the calculation of
percent leaking valves the first time the valve is identified as leaking
and nonrepairable and as required to comply with paragraph (e)(6)(iv)(B)
of this section. Otherwise, a number of nonrepairable valves (identified
and included in the percent leaking calculation in a previous period) up
to a maximum of 1 percent of the total number of valves in organic HAP
service at a process may be excluded from calculation of percent leaking
valves for subsequent monitoring periods.
(B) If the number of nonrepairable valves exceeds 1 percent of the
total number of valves in organic HAP service at a process, the number
of nonrepairable valves exceeding 1 percent of the total number of
valves in organic HAP service shall be included in the calculation of
percent leaking valves.
(7) Repair provisions. (i) When a leak is detected, it shall be
repaired as soon as practicable, but no later than 15 calendar days
after the leak is detected, except as provided in paragraph (b)(1)(v) of
this section.
(ii) A first attempt at repair shall be made no later than 5
calendar days after each leak is detected.
(iii) When a leak is repaired, the valve shall be monitored at least
once within the first 3 months after its repair. Days that the valve is
not in organic HAP service shall not be considered part of this 3 month
period.
(8) First attempts at repair include, but are not limited to, the
following practices where practicable:
(i) Tightening of bonnet bolts,
(ii) Replacement of bonnet bolts,
(iii) Tightening of packing gland nuts, and
(iv) Injection of lubricant into lubricated packing.
(9) Any equipment located at a plant site with fewer than 250 valves
in organic HAP service in the affected source is exempt from the
requirements for monthly monitoring specified in paragraph (e)(4)(i) of
this section. Instead, the owner or operator shall monitor each valve in
organic HAP service for leaks once each quarter, or comply with
paragraphs (e)(4)(iii) or (e)(4)(iv) of this section.

applicable.
(3) Equipment that is difficult to monitor. (i) Equipment may be
designated as difficult to monitor if the owner or operator determines
that the equipment cannot be monitored without elevating the monitoring
personnel more than 2 meters above a support surface or it is not
accessible at anytime in a safe manner;
(ii) At an existing source, any equipment within a group of
processes that meets the criteria of paragraph (f)(3)(i) of this section
may be designated as difficult to monitor. At a new affected source, an
owner or operator may designate no more than 3 percent of each type of
equipment as difficult to monitor.
(iii) The owner or operator of equipment designated as difficult to
monitor must follow a written plan that requires monitoring of the
equipment at least once per calendar year.

meets the criteria of paragraph (f)(4)(i) of this section may be
designated as inaccessible. At a new affected source, an owner or
operator may designate no more than 3 percent of each type of equipment
as inaccessible.
(iii) If any inaccessible equipment or ceramic or ceramic-lined
connector is observed by visual, audible, olfactory, or other means to
be leaking, the leak shall be repaired as soon as practicable, but no
later than 15 calendar days after the leak is detected, except as
provided in paragraph (g) of this section.
(g) Recordkeeping Requirements. (1) An owner or operator of more
than one group of processes subject to the provisions of this section
may comply with the recordkeeping requirements for the groups of
processes in one recordkeeping system if the system identifies with each
record the program being implemented (e.g., quarterly monitoring) for
each type of equipment. All records and information required by this

Sec. 63.1256 Standards: Wastewater.
(a) General. Each owner or operator of any affected source (existing
or new) shall comply with the general wastewater requirements in
paragraphs (a)(1) and (2) of this section.
(1) Identify wastewater that requires control. For each POD, the
owner or operator shall comply with the requirements in either paragraph
(a)(1)(i), or (ii) of this section to determine whether a wastewater
stream is an affected wastewater stream that requires control for
soluble and/or partially soluble HAP compounds or to designate the
wastewater stream as an affected wastewater stream, respectively. The
owner or operator may use a combination of the approaches in paragraphs
(a)(1)(i) and (ii) of this section for different affected wastewater
generated at the source. The owner or operator shall also comply with
the requirements for multiphase discharges in paragraph (a)(4) of this
section. Wastewater identified in paragraph (a)(3) of this section is
exempt from the provisions of this subpart.
(i) Determine characteristics of a wastewater stream. At new and
existing sources, a wastewater stream is an affected wastewater stream
if the annual average concentration and annual load exceed any of the
criteria specified in paragraph (a)(1)(i)(A) through (C) of this
section. At new sources, a wastewater stream is subject to additional
control requirements if the annual average concentration and annual load
exceed the criteria specified in paragraphs (a)(1)(i)(D) of this
section. The owner or operator shall comply with the provisions of
Sec. 63.1257(e)(1) to determine the annual average concentrations and
annual load of partially soluble and soluble HAP compounds.
[[Page 44]]
(A) The wastewater stream contains partially soluble HAP compounds
at an annual average concentration greater than 1,300 ppmw, and the
total soluble and partially soluble HAP load in all wastewater from the
PMPU exceeds 1 Mg/yr.
(B) The wastewater stream contains partially soluble and/or soluble
HAP compounds at an annual average concentration of 5,200 ppmw, and the
total soluble and partially soluble HAP load in all wastewater from the
PMPU exceeds 1 Mg/yr.
(C) The wastewater stream contains partially soluble and/or soluble
HAP at an annual average concentration of greater than 10,000 ppmw, and
the total partially soluble and/or soluble HAP load in all wastewater
from the affected source is greater than 1 Mg/yr.
(D) The wastewater stream contains soluble HAP compounds at an
annual average concentration greater than 110,000 ppmw, and the total
soluble and partially soluble HAP load in all wastewater from the PMPU
exceeds 1 Mg/yr.
(ii) Designate wastewater as affected wastewater. For existing
sources, the owner or operator may elect to designate wastewater streams
as meeting the criteria of either paragraphs (a)(1)(i)(A),(B), or (C) of
this section. For new sources, the owner or operator may elect to
designate wastewater streams meeting the criterion in paragraph
(a)(1)(i)(D) or for wastewater known to contain no soluble HAP, as
meeting the criterion in paragraph (a)(1)(i)(A) of this section. For
designated wastewater the procedures specified in paragraphs
(a)(1)(ii)(A) and (B) of this section shall be followed, except as
specified in paragraphs (g)(8)(i), (g)(9)(i), and (g)(10) of this
section. The owner or operator is not required to determine the annual
average concentration or load for each designated wastewater stream for
the purposes of this section.
(A) From the POD for the wastewater stream that is designated as an
affected wastewater stream to the location where the owner or operator
elects to designate such wastewater stream as an affected wastewater
stream, the owner or operator shall comply with all applicable emission
suppression requirements specified in paragraphs (b) through (f) of this
section.
(B) From the location where the owner or operator designates a
wastewater stream as an affected wastewater stream, such wastewater
stream shall be managed in accordance with all applicable emission
suppression requirements specified in paragraphs (b) through (f) of this
section and with the treatment requirements in paragraph (g) of this
section.
(iii) Scrubber Effluent. Effluent from a water scrubber that has
been used to control Table 2 HAP-containing vent streams that are
controlled in order to meet the process vent requirements in
Sec. 63.1254 of this subpart is considered an affected wastewater
stream.
(2) Requirements for affected wastewater. (i) An owner or operator
of a facility shall comply with the applicable requirements for
wastewater tanks, surface impoundments, containers, individual drain
systems, and oil/water separators as specified in paragraphs (b) through
(f) of this section, except as provided in paragraph (g)(3) of this
section.
(ii) Comply with the applicable requirements for control of soluble
and partially soluble compounds as specified in paragraph (g) of this
section. Alternatively, the owner or operator may elect to comply with
the treatment provisions specified in paragraph (a)(5) of this section.
(iii) Comply with the applicable monitoring and inspection
requirements specified in Sec. 63.1258.
(iv) Comply with the applicable recordkeeping and reporting

paragraph (g)(13) of this section.
(5) Offsite treatment or onsite treatment not owned or operated by
the source. The owner or operator may elect to transfer affected
wastewater streams that contain less than 50 ppmw of partially soluble
HAP or a residual removed from such affected wastewater to an onsite
treatment operation not owned or operated by the owner or operator of
the source generating the wastewater or residual, or to an offsite
treatment operation, provided that the waste management units up to the
activated sludge unit are covered or the owner or operator demonstrates
that less than 5 percent of the total soluble HAP is emitted from the
these units.
(i) The owner or operator transferring the wastewater or residual
shall:
(A) Comply with the provisions specified in paragraphs (b) through
(f) of this section for each waste management unit that receives or
manages affected wastewater or a residual removed from affected
wastewater prior to shipment or transport.
(B) Include a notice with each shipment or transport of affected
wastewater or residual removed from affected wastewater. The notice
shall state that the affected wastewater or residual contains organic
HAP that are to be treated in accordance with the provisions of this
subpart. When the transport is continuous or ongoing (for example,
discharge to a publicly-owned treatment works), the notice shall be
submitted to the treatment operator initially and whenever there is a
change in the required treatment. The owner or operator shall keep a
record of the notice in accordance with Sec. 63.1259(g).
(ii) The owner or operator may not transfer the affected wastewater
or residual unless the transferee has submitted to the EPA a written

wastewater or residual removed from affected wastewater received from a
source subject to the requirements of this subpart in accordance with
the requirements of either:
(A) Paragraphs (b) through (i) of this section; or
(B) Subpart D of this part if alternative emission limitations have
been granted the transferor in accordance with those provisions; or
(C) Section 63.6(g).
(iii) The certifying entity may revoke the written certification by
sending a written statement to the EPA and the owner or operator giving
at least 90 days notice that the certifying entity is rescinding
acceptance of responsibility for compliance with the regulatory
provisions listed in this paragraph. Upon expiration of the notice
period, the owner or operator may not transfer the wastewater stream or
residual to the treatment operation.
(iv) By providing this written certification to the EPA, the
certifying entity accepts responsibility for compliance with the
regulatory provisions listed in paragraph (a)(5)(ii) of this section
with respect to any shipment of wastewater or residual covered by the
written certification. Failure to abide by any of those provisions with
respect to such shipments may result in enforcement action by the EPA
against the certifying entity in accordance with the enforcement
provisions applicable to violations of these provisions by owners or
operators of sources.
(v) Written certifications and revocation statements, to the EPA
from the transferees of wastewater or residuals shall be signed by the
responsible official of the certifying entity, provide the name and
address of the certifying entity, and be sent to the appropriate EPA
Regional Office at the addresses listed in Sec. 63.13. Such written
certifications are not transferable by the treater.
(b) Wastewater tanks. For each wastewater tank that receives,
manages, or treats affected wastewater or a residual removed from

of this section are required to demonstrate initial compliance with
Secs. 63.1253, 63.1254, 63.1256, and 63.1252(e), respectively. The
provisions in paragraphs (a) (2) through (3) apply to performance tests
that are specified in paragraphs (c), (d), and (e) of this section. The
provisions in paragraph (a)(5) of this section are used to demonstrate
initial compliance with the alternative standards specified in
Secs. 63.1253(d) and 63.1254(c). The provisions in paragraph (a)(6) of
this section are used to comply with the outlet concentration
requirements specified in Secs. 63.1253(c), 63.1254 (a)(2)(i) and
(a)(3)(ii)(B), 63.1254(b)(i) and 63.1256(h)(2).
(1) Design evaluation. To demonstrate that a control device meets
the required control efficiency, a design evaluation must address the
composition and organic HAP concentration of the vent stream entering
the control device. A design evaluation also must address other vent
stream characteristics and control device operating parameters as
specified in any one of paragraphs (a)(1) (i) through (vi) of this
section, depending on the type of control device that is used. If the
vent stream is not the only inlet to the control device, the efficiency
demonstration also must consider all other vapors, gases, and liquids,
other than fuels, received by the control device.
(i) For an enclosed combustion device used to comply with the
provisions of 63.1253 (b)(2) or (c)(2), or 63.1256(h)(2)(i)(C) with a
minimum residence time of 0.5 seconds and a minimum temperature of
760 deg.C, the design evaluation must document that these conditions
exist.
(ii) For a combustion control device that does not satisfy the
criteria in paragraph (a)(1)(i) of this section, the design evaluation
must document control efficiency and address the following
characteristics, depending on the type of control device:
(A) For a thermal vapor incinerator, the design evaluation must
consider the autoignition temperature of the organic HAP, must consider
the vent stream flow rate, and must establish the design minimum and
average temperature in the combustion zone and the combustion zone
residence time.
(B) For a catalytic vapor incinerator, the design evaluation shall
consider the vent stream flow rate and shall establish the design
minimum and average temperatures across the catalyst bed inlet and
outlet.
(C) For a boiler or process heater, the design evaluation shall
consider the vent stream flow rate; shall establish the design minimum
and average flame
[[Page 59]]
zone temperatures and combustion zone residence time; and shall describe
the method and location where the vent stream is introduced into the
flame zone.
(iii) For a condenser, the design evaluation shall consider the vent
stream flow rate, relative humidity, and temperature and shall establish
the design outlet organic HAP compound concentration level, design
average temperature of the condenser exhaust vent stream, and the design
average temperatures of the coolant fluid at the condenser inlet and
outlet. The temperature of the gas stream exiting the condenser must be
measured and used to establish the outlet organic HAP concentration.
(iv) For a carbon adsorption system that regenerates the carbon bed
directly onsite in the control device such as a fixed-bed adsorber, the
design evaluation shall consider the vent stream flow rate, relative
humidity, and temperature and shall establish the design exhaust vent
stream organic compound concentration level, adsorption cycle time,
number and capacity of carbon beds, type and working capacity of
activated carbon used for carbon beds, design total regeneration stream
mass or volumetric flow over the period of each complete carbon bed
regeneration cycle, design carbon bed temperature after regeneration,
design carbon bed regeneration time, and design service life of carbon.
For vacuum desorption, the pressure drop shall be included.
(v) For a carbon adsorption system that does not regenerate the
carbon bed directly onsite in the control device such as a carbon
canister, the design evaluation shall consider the vent stream mass or
volumetric flow rate, relative humidity, and temperature and shall
establish the design exhaust vent stream organic compound concentration
level, capacity of carbon bed, type and working capacity of activated
carbon used for carbon bed, and design carbon replacement interval based
on the total carbon working capacity of the control device and source
operating schedule.
(vi) For a scrubber, the design evaluation shall consider the vent
stream composition; constituent concentrations; liquid-to-vapor ratio;
scrubbing liquid flow rate and concentration; temperature; and the
reaction kinetics of the constituents with the scrubbing liquid. The
design evaluation shall establish the design exhaust vent stream organic
compound concentration level and will include the additional information
in paragraphs (a)(1)(vi)(A) and (B) of this section for trays and a
packed column scrubber.
(A) Type and total number of theoretical and actual trays;
(B) Type and total surface area of packing for entire column, and
for individual packed sections if column contains more than one packed
section.
(2) Calculation of TOC or total organic HAP concentration. The TOC
concentration or total organic HAP concentration is the sum of the
concentrations of the individual components. If compliance is being
determined based on TOC, the owner or operator shall compute TOC for
each run using Equation 6 of this subpart. If compliance with the
wastewater provisions is being determined based on total organic HAP,
the owner or operator shall compute total organic HAP using Equation 6
of this subpart, except that only the organic HAP compounds shall be
summed; when determining compliance with paragraph (e)(3)(i) of this
section, only the soluble and partially soluble HAP compounds shall be
summed.

(3) Percent oxygen correction for combustion control devices. If the
control device is a combustion device, the TOC or total organic HAP
concentrations must be corrected to 3 percent oxygen. The
[[Page 60]]
integrated sampling and analysis procedures of Method 3B of 40 CFR part
60, appendix A shall be used to determine the actual oxygen

demonstrated when the outlet TOC concentration is 20 ppmv or less, and
the outlet hydrogen halide and halogen concentration is 20 ppmv or less.
To demonstrate initial compliance, the owner or operator shall be in
compliance with the monitoring provisions in Sec. 63.1258(b)(5) on the
initial compliance date. The owner or operator shall use Method 18 to
determine the predominant organic HAP in the emission stream if the TOC
monitor is calibrated on the predominant HAP.
(6) Initial compliance with the 20 ppmv outlet limit. Initial
compliance with the 20 ppmv TOC and hydrogen halide and halogen
concentration is demonstrated when the outlet TOC concentration is 20
ppmv or less, and the outlet hydrogen halide and halogen concentration
is 20 ppmv or less. To demonstrate initial compliance, the operator
shall use test methods described in paragraph (b) of this section. The
owner or operator shall comply with the monitoring provisions in
Sec. 63.1258(b)(1) through (5) of this subpart on the initial compliance
date.

when the instrument is zeroed on the most sensitive scale.
(C) The span value of the analyzer must be less than 100 ppmv.
(7) Testing conditions for continuous processes. Testing of
emissions on equipment operating as part of a continuous process will
consist of three l-hour runs. Gas stream volumetric flow rates shall be
measured every 15 minutes during each 1-hour run. The HAP concentration
shall be determined from samples collected in an integrated sample over
the duration of each l-hour test run, or from grab samples collected
simultaneously with the flow rate measurements (every 15 minutes). If an
integrated sample is collected for laboratory analysis, the sampling
rate shall be adjusted proportionally to reflect variations in flow
rate. For continuous gas streams, the emission rate used to determine
compliance shall be the average emission rate of the three test runs.
(8) Testing and compliance determination conditions for batch
processes. Testing of emissions on equipment where the flow of gaseous
emissions is intermittent (batch operations) shall be conducted as
specified in paragraphs (b)(8)(i) through (iii) of this section.
(i) Except as provided in paragraph (b)(9) of this section for
condensers, testing shall be conducted at absolute worst-case conditions
or hypothetical worst-case conditions. Gas stream volumetric flow rates
shall be measured at 15-minute intervals. The HAP or TOC concentration
shall be determined from samples collected in an integrated sample over
the duration of the test, or from grab samples collected simultaneously
with the flow rate measurements (every 15 minutes). If an integrated
sample is collected for laboratory analysis, the sampling rate shall be
adjusted proportionally to reflect variations in flow rate. The absolute
worst-case or hypothetical worst-case conditions shall be characterized
by the criteria presented in paragraphs (b)(8)(i)(A) and (B)of this
section. In all cases, a site-specific plan shall be submitted to the
Administrator for approval prior to testing in accordance with
Sec. 63.7(c) and Sec. 63.1260(l). The test plan shall include the
emission profile described in paragraph (b)(8)(ii) of this section.
(A) Absolute worst-case conditions are defined by the criteria
presented in paragraph (b)(8)(i)(A)(1) or (2) of this section if the
maximum load is the most challenging condition for the control device.
Otherwise, absolute worst-case conditions are defined by the conditions
in paragraph (b)(8)(i)(A)(3) of this section.
(1) The period in which the inlet to the control device will contain
at least 50 percent of the maximum HAP load (in lb) capable of being
vented to the control device over any 8 hour period. An emission profile
as described in paragraph (b)(8)(ii)(A) of this section shall be used to
identify the 8-hour period that includes the maximum projected HAP load.
(2) A 1-hour period of time in which the inlet to the control device
will contain the highest HAP mass loading rate, in lb/hr, capable of
being vented
[[Page 62]]
to the control device. An emission profile as described in paragraph
(b)(8)(ii)(A) of this section shall be used to identify the 1-hour
period of maximum HAP loading.
(3) The period of time when the HAP loading or stream composition
(including non-HAP) is most challenging for the control device. These
conditions include, but are not limited to the following:
(i) Periods when the stream contains the highest combined VOC and
HAP load, in lb/hr, described by the emission profiles in (b)(8)(ii);
(ii) Periods when the streams contain HAP constituents that approach
limits of solubility for scrubbing media;
(iii) Periods when the streams contain HAP constituents that
approach limits of adsorptivity for carbon adsorption systems.
(B) Hypothetical worst-case conditions are simulated test conditions
that, at a minimum, contain the highest hourly HAP load of emissions
that would be predicted to be vented to the control device from the
emissions profile described in paragraph (b)(8)(ii)(B) or (C) of this
section.
(ii) Emissions profile. The owner or operator may choose to perform
tests only during those periods of the worst-case conditions that the
owner or operator selects to control as part of achieving the required
emission reduction. The owner or operator must develop an emission
profile for the vent to the control device that describes the
characteristics of the vent stream at the inlet to the control device
under worst case conditions. The emission profile shall be developed
based on any one of the procedures described in (b)(8)(ii)(A) through
(C) of this section, as required by paragraph (b)(8)(i).
(A) Emission profile by process. The emission profile must consider
all emission episodes that could contribute to the vent stack for a
period of time that is sufficient to include all processes venting to
the stack and shall consider production scheduling. The profile shall
describe the HAP load to the device that equals the highest sum of
emissions from the episodes that can vent to the control device in any
given hour. Emissions per episode shall be calculated using the
procedures specified in paragraph (d)(2) of this section. Emissions per
episode shall be divided by the duration of the episode only if the
duration of the episode is longer than 1 hour.
(B) Emission profile by equipment. The emission profile must consist
of emissions that meet or exceed the highest emissions, in lb/hr, that
would be expected under actual processing conditions. The profile shall
describe equipment configurations used to generate the emission events,
volatility of materials processed in the equipment, and the rationale
used to identify and characterize the emission events. The emissions may
be based on using a compound more volatile than compounds actually used
in the process(es), and the emissions may be generated from all
equipment in the process(es) or only selected equipment.
(C) Emission profile by capture and control device limitation. The
emission profile shall consider the capture and control system
limitations and the highest emissions, in lb/hr, that can be routed to
the control device, based on maximum flowrate and concentrations
possible because of limitations on conveyance and control equipment
(e.g., fans, LEL alarms and safety bypasses).
(iii) Three runs, at a minimum of 1 hour each and a maximum of 8
hours each, are required for performance testing. Each run must occur
over the same worst-case conditions, as defined in paragraph (b)(8)(i)
of this section.
(9) Testing requirements for condensers. For emission streams
controlled using condensers, continuous direct measurement of condenser
outlet gas temperature to be used in determining concentrations per the
design evaluation described in Sec. 63.1257(a)(1)(iii) is required.
(10) Wastewater testing. Wastewater analysis shall be conducted in
accordance with paragraph (b)(10)(i), (ii), (iii), or (iv) of this
section.

appendix A and comply with requirements in paragraph (b)(10)(v) of this
section.
(iii) Other EPA Methods. Use procedures specified in the method,
validate the method using the procedures in paragraph (b)(10)(iii)(A) or
(B) of this section, and comply with the procedures in paragraph
(b)(10)(v) of this section.
(A) Validate the method according to section 5.1 or 5.3 of Method
301 of 40 CFR part 63, appendix A.
(B) Follow the procedure as specified in ``Alternative Validation
Procedure for EPA Waste Methods'' 40 CFR part 63, appendix D.
(iv) Methods other than an EPA method. Use procedures specified in
the method, validate the method using the procedures in paragraph
(b)(10)(iii)(A) of this section, and comply with the requirements in
paragraph (b)(10)(v) of this section.
(v) Sampling plan. The owner or operator shall prepare a sampling
plan. Wastewater samples shall be collected using sampling procedures
which minimize loss of organic compounds during sample collection and
analysis and maintain sample integrity. The sample plan shall include
procedures for determining recovery efficiency of the relevant partially
soluble and soluble HAP compounds. An example of an acceptable sampling
plan would be one that incorporates similar sampling and sample handling
requirements to those of Method 25D of 40 CFR part 60, appendix A. The
sampling plan shall be maintained at the facility.
(c) Initial compliance with storage tank provisions. The owner or
operator of an affected storage tank shall demonstrate initial
compliance with Sec. 63.1253(b) or (c), as applicable, by fulfilling the
requirements of paragraph (c)(1),or (c)(2), or (c)(3) of this section.
(1) Performance test. If this option is chosen to demonstrate
initial compliance with the percent reduction requirement of
Sec. 63.1253(b)(1) or (c)(1)(i), the efficiency of the control device
shall be calculated using performance test data as specified in
paragraphs (c)(1)(i) through (iii) of this section. Initial compliance
with the outlet concentration requirement of Sec. 63.1253(b)(2) or
(c)(1)(ii) is demonstrated by fulfilling the requirements of paragraph
(a)(6) of this section.
(i) Equations 8 and 9 of this subpart shall be used to calculate the
mass rate of total HAP reasonably expected maximum filling rate at the
inlet and outlet of the control device for standard conditions of
20 deg.C: where:

device shall be determined by applying the control efficiency of the
large control device to the estimated uncontrolled emissions. The
control efficiency shall be determined by conducting a performance test
on the control device as described in paragraphs (d)(3)(ii)(A) through
(C) of this section, or by using the results of a previous performance
test as described in paragraph (d)(4) of this section. If the control
device is intended to control only hydrogen halides and halogens, the
owner or operator may assume the control efficiency of organic HAP is
zero percent. If the control device is intended to control only organic
HAP, the owner or operator may assume the control efficiency for
hydrogen halides and halogen is zero percent. Owners and operators are
not required to conduct performance tests for devices described in
paragraphs (a)(4) and (d)(4) of this section that are large control
devices, as defined in Sec. 63.1251.
(A) The performance test shall be conducted by performing emission
testing on the inlet and outlet, or, if complying with the provisions of
Sec. 63.1254(c), on the outlet of the control device, following the test
methods and procedures of Sec. 63.1257(b). Concentrations shall be
calculated from the data obtained through emission testing according to
the procedures in paragraph (a)(2) of this section. If the control
device is a combustion device that uses supplemental combustion air, the
concentrations shall be corrected to 3 percent oxygen according to the
procedures in paragraph (a)(3) of this section.
(B) Performance testing shall be conducted under absolute, or
hypothetical worst-case conditions, as defined in paragraphs
(b)(8)(i)(A) through (B) of this section.
(C) The owner or operator may elect to conduct more than one
performance test on the control device for the purpose of establishing
more than one operating condition at which the control device achieves
the required control efficiency.
(4) An owner or operator is not required to conduct a performance
test for the following:
(i) Any control device for which a previous performance test was
conducted, provided the test was conducted using the same procedures
specified in Sec. 63.1257(b) over conditions typical of the appropriate
worst-case, as defined in Sec. 63.1257(b)(8)(i). The results of the
previous performance test shall be used to demonstrate compliance.
(e) Compliance with wastewater provisions. (1) Determining annual
average concentration and annual load. To determine the annual average
concentration and annual load of partially soluble and/or soluble HAP
compounds in a wastewater stream, as required by Sec. 63.1256(a)(1), an
owner or operator shall comply with the provisions in paragraphs
(e)(1)(i) through (iii) of this section. A wastewater stream is exempt
from the requirements of Sec. 63.1256(a)(2) if the owner or operator
determines the annual average concentration and annual load are below
all of the applicability cutoffs specified in Sec. 63.1256(a)(1)(i)(A)
through (D). For annual average concentration, only initial rinses are
included. Concentration measurements based on Method 305 shall be
adjusted by dividing each concentration by the compound-specific Fm
factor listed in Table 8 of this subpart. Concentration measurements
based on methods other than Method 305 may not be adjusted by the
compound-specific Fm factor listed in Table 8 of this subpart.
(i) Annual average concentration definition. (A) When complying with
Sec. 63.1256(a)(1)(i)(A), the annual average concentration means the
total mass of partially soluble HAP compounds occurring in the
wastewater stream during the calendar year divided by the total mass of
the wastewater stream discharged during the same calendar year.
(B) When complying with Sec. 63.1256(a)(1)(i) (B) or (C), the annual
[[Page 77]]
average concentration means the total mass of partially soluble and/or
soluble HAP compounds occurring in the wastewater stream during the
calendar year divided by the total mass of the wastewater stream
discharged during the same calendar year.
(C) When complying with Sec. 63.1256(a)(1)(i)(D), the annual average
concentration means the total mass of soluble HAP compounds occurring in
the wastewater stream during the calendar year divided by the total mass
of the wastewater stream discharged during the same calendar year.
(ii) Determination of annual average concentration. An owner or
operator shall determine annual average concentrations of partially
soluble and/or soluble HAP compounds in accordance with the provisions
specified in paragraph (e)(1)(ii)(A), (B), or (C) of this section. The
owner or operator may determine annual average concentrations by process
simulation. Data and other information supporting the simulation shall
be reported in the Precompliance Report for approval by the
Administrator. The annual average concentration shall be determined
either at the POD or downstream of the POD with adjustment for
concentration changes made according to paragraph (e)(1)(ii)(D) of this
section.
(A) Test methods. The concentration of partially soluble HAP,
soluble HAP, or total HAP shall be measured using any of the methods
described in paragraphs (b)(10)(i) through (iv) of this section.
(B) Knowledge of the wastewater stream. The concentration of
partially soluble HAP, soluble HAP, or total HAP shall be calculated
based on knowledge of the wastewater stream according to the procedures
in paragraphs (e)(1)(ii)(B)(1) and (2) of this section. The owner or
operator shall document concentrations in the Notification of Compliance
Status report described in Sec. 63.1260(f).
(1) Mass balance. The owner or operator shall calculate the
concentrations of HAP compounds in wastewater considering the total
quantity of HAP discharged to the water, the amount of water at the POD,
and the amounts of water and solvent lost to other mechanisms such as
reactions, air emissions, or uptake in product or other processing
materials. The quantities of HAP and water shall be based on batch
sheets, manufacturing tickets, or FDA bills of materials. In cases where
a chemical reaction occurs that generates or consumes HAP, the amount of
HAP remaining after a reaction shall be based on stoichometry assuming
100 percent theoretical consumption or yield, as applicable.
(2) Published water solubility data. For single components in water,
owners and operators may use the water solubilities published in
standard reference texts at the POD temperature to determine maximum HAP
concentration.
(C) Bench scale or pilot-scale test data. The concentration of
partially soluble HAP, soluble HAP, or total HAP shall be calculated
based on bench scale or pilot-scale test data. The owner or operator
shall provide sufficient information to demonstrate that the bench-scale
or pilot-scale test concentration data are representative of actual HAP
concentrations. The owner or operator shall also provide documentation
describing the testing protocol, and the means by which sample
variability and analytical variability were accounted for in the
determination of HAP concentrations. Documentation of the pilot-scale or
bench scale analysis shall be provided in the precompliance report.
(D) Adjustment for concentrations determined downstream of the POD.
The owner or operator shall make corrections to the annual average
concentration when the concentration is determined downstream of the POD
at a location where: two or more wastewater streams have been mixed; one
or more wastewater streams have been treated; or, losses to the
atmosphere have occurred. The owner or operator shall make the
adjustments either to the individual data points or to the final annual
average concentration.
(iii) Determination of annual load. An owner or operator shall
calculate the partially soluble and/or soluble HAP load in a wastewater
stream based on the annual average concentration determined in paragraph
(e)(1)(ii) (A), (B), or (C) of this section and the total volume of the
wastewater stream, based
[[Page 78]]
on knowledge of the wastewater stream in accordance with paragraphs
(e)(1)(ii)(B) of this section. The owner or operator shall maintain
records of the total liters of wastewater discharged per year as
specified in Sec. 63.1259(b).
(2) Compliance with treatment unit control provisions. (i)
Performance tests and design evaluations-general. To comply with the
control options in Sec. 63.1256(g) (10) or (13), neither a design
evaluation nor a performance test is required. For any other
nonbiological treatment process, the owner or operator shall conduct
either a design evaluation as specified in paragraph (e)(2)(ii) of this
section, or a performance test as specified in paragraph (e)(2)(iii) of
this section to demonstrate that each nonbiological treatment process
used to comply with Sec. 63.1256(g) (8), (9), and/or (12) achieves the
conditions specified for compliance. The owner or operator shall
demonstrate by the procedures in either paragraph (e)(2) (ii) or (iii)
of this section that each closed biological treatment process used to
comply with Sec. 63.1256 (g)(8)(ii), (g)(9)(ii), (g)(11), or (g)(12)
achieves the conditions specified for compliance. If an open biological
treatment unit is used to comply with Sec. 63.1256 (g)(8)(ii),
(g)(9)(ii), (g)(11), or (g)(12), the owner or operator shall comply with
the performance test requirements in paragraph (e)(2)(iii) of this
section.
(ii) Design evaluation. A design evaluation and supporting
documentation that addresses the operating characteristics of the
treatment process and that is based on operation at a wastewater stream
flow rate and a concentration under which it would be most difficult to
demonstrate compliance. For closed biological treatment processes, the
percent reduction from removal/destruction in the treatment unit and
control device shall be determined by a mass balance over the unit. The
mass flow rate of soluble and/or partially soluble HAP compounds exiting
the treatment process shall be the sum of the mass flow rate of soluble
and/or partially soluble HAP compounds in the wastewater stream exiting
the biological treatment process and the mass flow rate of the vented
gas stream exiting the control device. The mass flow rate entering the
treatment process minus the mass flow rate exiting the process
determines the actual mass removal. Compounds that meet the requirements
specified in paragraph (e)(2)(iii)(A)(4) of this section are not
required to be included in the design evaluation; the term ``performance
test'' in paragraph (e)(2)(iii)(A)(4) of this section shall mean
``design evaluation'' for the purposes of this paragraph.
(iii) Performance tests. Performance tests shall be conducted using
test methods and procedures that meet the applicable requirements
specified in paragraphs (e)(2)(iii)(A) through (G) of this section.
(A) General. This paragraph specifies the general procedures for
performance tests that are conducted to demonstrate compliance of a
treatment process with the control requirements specified in
Sec. 63.1256(g).
(1) Representative process unit operating conditions. Compliance
shall be demonstrated for representative operating conditions.
Operations during periods of malfunction and periods of nonoperation
shall not constitute representative conditions. The owner or operator
shall record the process information that is necessary to document
operating conditions during the test.
(2) Representative treatment process operating conditions.
Performance tests shall be conducted when the treatment process is
operating at a representative inlet flow rate and concentration. If the
treatment process will be operating at several different sets of
representative operating conditions, the owner or operator shall comply
with paragraphs (e)(2)(iii)(A)(2)(i) and (ii) of this section. The owner
or operator shall record information that is necessary to document
treatment process or control device operating conditions during the
test.
(i) Range of operating conditions. If the treatment process will be
operated at several different sets of representative operating
conditions, performance testing over the entire range is not required.
In such cases, the performance test results shall be supplemented with
modeling and/or engineering assessments to demonstrate performance over
the operating range.
[[Page 79]]
(ii) Consideration of residence time. If concentration and/or flow
rate to the treatment process are not relatively constant (i.e.,
comparison of inlet and outlet data will not be representative of
performance), the owner or operator shall consider residence time, when
determining concentration and flow rate.
(3) Testing equipment. All testing equipment shall be prepared and
installed as specified in the applicable test methods, or as approved by
the Administrator.
(4) Compounds not required to be considered in performance tests.
Compounds that meet the requirements specified in (e)(2)(iii)(A)(4)(i),
(ii), or (iii) of this section are not required to be included in the
performance test. Concentration measurements based on Method 305 shall
be adjusted by dividing each concentration by the compound-specific Fm
factor listed in Table 8 of this subpart. Concentration measurements
based on methods other than Method 305 shall not be adjusted by the
compound-specific Fm factor listed in Table 8 of this subpart.
(i) Compounds not used or produced by the PMPU; or
(ii) Compounds with concentrations at the POD that are below 1 ppmw;
or
(iii) Compounds with concentrations at the POD that are below the
lower detection limit where the lower detection limit is greater than 1
ppmw. The method shall be an analytical method for wastewater which has
the compound of interest as a target analyte.
(5) Treatment using a series of treatment processes. In all cases
where the wastewater provisions in this subpart allow or require the use
of a treatment process to comply with emissions limitations, the owner
or operator may use multiple treatment processes. The owner or operator
complying with the requirements of Sec. 63.1256(g)(7)(i), when
wastewater is conveyed by hard-piping, shall comply with either
paragraph (e)(2)(iii)(A)(5)(i) or (ii) of this section. The owner or
operator complying with the requirements of Sec. 63.1256(g)(7)(ii) shall
comply with the requirements of paragraph (e)(2)(iii)(A)(5)(ii) of this
section.
(i) The owner or operator shall conduct the performance test across
each series of treatment processes. For each series of treatment
processes, inlet concentration and flow rate shall be measured either
where the wastewater enters the first treatment process in a series of
treatment processes, or prior to the first treatment process as
specified in paragraph (e)(2)(iii)(A)(6) of this section. For each
series of treatment processes, outlet concentration and flow rate shall
be measured where the wastewater exits the last treatment process in the
series of treatment processes, except when the last treatment process is
an open or a closed aerobic biological treatment process demonstrating
compliance by using the procedures in paragraphs (e)(2)(iii)(E) or (F)
of this section. When the last treatment process is either an open or a
closed aerobic biological treatment process demonstrating compliance by
using the procedures in paragraphs (e)(2)(iii)(E) or (F) of this
section, inlet and outlet concentrations and flow rates shall be
measured at the inlet and outlet to the series of treatment processes
prior to the biological treatment process and at the inlet to the
biological treatment process, except as provided in paragraph
(e)(2)(iii)(A)(6)(ii) of this section. The mass flow rate destroyed in
the biological treatment process for which compliance is demonstrated
using paragraph (e)(2)(iii)(E) or (F) of this section shall be added to
the mass flow rate removed or destroyed in the series of treatment units
before the biological treatment unit. This sum shall be used to
calculate the overall control efficiency.
(ii) The owner or operator shall conduct the performance test across
each treatment process in the series of treatment processes. The mass
flow rate removed or destroyed by each treatment process shall be added
together and the overall control efficiency calculated to determine
whether compliance has been demonstrated using paragraphs
(e)(2)(iii)(C), (D), (E), (F), or (G) of this section, as applicable. If
a biological treatment process is one of the treatment processes in the
series of treatment processes, the inlet to the biological treatment
process shall be the point at which the wastewater enters the biological
treatment process, or the inlet to the equalization tank if
[[Page 80]]
all the criteria of paragraph (e)(2)(iii)(A)(6)(ii) of this section are
met.
(6) The owner or operator determining the inlet for purposes of
demonstrating compliance with paragraph (e)(2)(iii)(E), or (F)of this
section may elect to comply with paragraph (e)(2)(iii)(A)(6)(i) or (ii)
of this section.
(i) When wastewater is conveyed exclusively by hard-piping from the
point of determination to a treatment process that is either the only
treatment process or the first in a series of treatment processes (i.e.,
no treatment processes or other waste management units are used upstream
of this treatment process to store, handle, or convey the wastewater),
the inlet to the treatment process shall be at any location from the
point of determination to where the wastewater stream enters the
treatment process. When samples are taken upstream of the treatment
process and before wastewater streams have converged, the owner or
operator shall ensure that the mass flow rate of all affected wastewater
is accounted for when using Sec. 63.1256(g)(8)(ii), (g)(9)(ii) or
(g)(12) of this subpart to comply and that the mass flow rate of all
wastewater, not just affected wastewater, is accounted for when using
Sec. 63.1256(g)(11) to comply, except as provided in paragraph
(e)(2)(iii)(A)(4) of this section.
(ii) The owner or operator may consider the inlet to the
equalization tank as the inlet to the biological treatment process if
the wastewater is conveyed by hard-piping from either the last previous
treatment process or the point of determination to the equalization
tank; or the wastewater is conveyed from the equalization tank
exclusively by hard-piping to the biological treatment process and no
treatment processes or other waste management units are used to store,
handle, or convey the wastewater between the equalization tank and the
biological treatment process; or the equalization tank is equipped with
a fixed roof and a closed-vent system that routes emissions to a control
device that meets the requirements of Sec. 63.1256(b)(1)(i) through (iv)
and Sec. 63.1256(b)(2)(i). The outlet from the series of treatment
processes prior to the biological treatment process is the point at
which the wastewater exits the last treatment process in the series
prior to the equalization tank, if the equalization tank and biological
treatment process are part of a series of treatment processes. The owner
or operator shall ensure that the mass flow rate of all affected
wastewater is accounted for when using Sec. 63.1256(g)(9)(ii) or (12) to
comply and that the mass flow rate of all wastewater, not just affected
wastewater is accounted for when using Sec. 63.1256(g)(11) to comply,
except as provided in paragraph (e)(2)(iii)(A)(4) of this section.
(B) Noncombustion treatment process--concentration limits. This
paragraph applies to performance tests that are conducted to demonstrate
compliance of a noncombustion treatment process with the ppmw wastewater
stream concentration limits at the outlet of the treatment process. This
compliance option is specified in Sec. 63.1256(g)(8)(i) and (9)(i).
Wastewater samples shall be collected using sampling procedures which
minimize loss of organic compounds during sample collection and analysis
and maintain sample integrity per paragraph (b)(10)(iii) of this
section. Samples shall be collected and analyzed using the procedures
specified in paragraphs (b)(10)(i), (ii), and (iii) of this section.
Samples may be grab samples or composite samples. Samples shall be taken
at approximately equally spaced time intervals over a 1-hour period.
Each 1-hour period constitutes a run, and the performance test shall
consist of a minimum of three runs. Concentration measurements based on
methods other than Method 305 may be adjusted by multiplying each
concentration by the compound-specific Fm factor listed in Table 8 of
this subpart. (For affected wastewater streams that contains both
partially soluble and soluble HAP compounds, compliance is demonstrated
only if the sum of the concentrations of partially soluble HAP compounds
is less than 50 ppmw, and the sum of the concentrations of soluble HAP
compounds is less than 520 ppmw.)
(C) Noncombustion, nonbiological treatment process: percent mass
removal/destruction option. This paragraph applies to performance tests
that are conducted to demonstrate compliance of a
[[Page 81]]
noncombustion, nonbiological treatment process with the percent mass
removal limits specified in Sec. 63.1256(g)(8)(ii) and (9)(ii) for
partially soluble and soluble HAP compounds, respectively. The owner or
operator shall comply with the requirements specified in paragraphs
(e)(2)(iii)(C)(1) through (5) of this section.
(1) Concentration. The concentration of partially soluble and/or
soluble HAP compounds entering and exiting the treatment process shall
be determined as provided in this paragraph. Wastewater samples shall be
collected using sampling procedures which minimize loss of organic
compounds during sample collection and analysis and maintain sample
integrity per paragraph (b)(10)(v) of this section. The method shall be
an analytical method for wastewater which has the compound of interest
as a target analyte. Samples may be grab samples or composite samples.
Samples shall be taken at approximately equally spaced time intervals
over a 1-hour period. Each 1-hour period constitutes a run, and the
performance test shall consist of a minimum of three runs. Concentration
measurements based on Method 305 shall be adjusted by dividing each
concentration by the compound-specific Fm factor listed in Table 8 of
this subpart. Concentration measurements based on methods other than
Method 305 shall not be adjusted by the compound-specific Fm factor
listed in Table 8 of this subpart.
(2) Flow rate. The flow rate of the entering and exiting wastewater
streams shall be determined using inlet and outlet flow meters,
respectively. Where the outlet flow is not greater than the inlet flow,
a single flow meter may be used, and may be used at either the inlet or
outlet. Flow rate measurements shall be taken at the same time as the
concentration measurements.
(3) Calculation of mass flow rate--for noncombustion, nonbiological
treatment processes. The mass flow rates of partially soluble and/or
soluble HAP compounds entering and exiting the treatment process are
calculated using Equations 44 and 45 of this subpart.

(5) Compare mass removal efficiency to required efficiency. Compare
the mass removal efficiency (calculated in Equation 44 of this subpart)
to the required efficiency as specified in Sec. 63.1256(g)(8)(ii) or
(9)(ii). If complying with Sec. 63.1256(g)(8)(ii), compliance is
demonstrated if the mass removal efficiency is 99 percent or greater. If
complying with Sec. 63.1256(g)(9)(ii), compliance is demonstrated if the
mass removal efficiency is 90 percent or greater.

option. This paragraph applies to performance tests that are conducted
to demonstrate compliance of a combustion treatment process with the
percent mass destruction limits specified in Sec. 63.1256(g)(8)(ii) for
partially soluble HAP compounds, and/or Sec. 63.1256(g)(9)(ii) for

be taken at approximately equally spaced time intervals over a 1-hour
period. Each 1-hour period constitutes a run, and the performance test
shall consist of a minimum of three runs. Concentration measurements
based on Method 305 of appendix A of this part shall be adjusted by
dividing each concentration by the compound-specific Fm factor listed in

treatment process. The volumetric flow rate of the vented gas stream
exiting the combustion treatment process shall be determined using
Method 2, 2A, 2C, or 2D of 40 CFR part 60, appendix A, as appropriate.
Volumetric flow rate measurements shall be taken at the same time as the

test is conducted, the monitoring parameter level shall be established
according to the procedures in (b)(3)(ii) of this section.
(ii) Large control devices. For devices controlling greater than 10
tons per year of HAP for which a performance test is required, the
parameter level must be established as follows:
(A) If the operating parameter level to be established is a maximum,
it must be based on the average of the values from each of the three
test runs.
(B) If the operating parameter level to be established is a minimum,
it must be based on the average of the values from each of the three
test runs.
(C) The owner or operator may establish the parametric monitoring
level(s) based on the performance test supplemented by engineering
assessments and manufacturer's recommendations. Performance testing is
not required to be conducted over the entire range of expected parameter
values. The rationale for the specific level for each parameter,
including any data and calculations used to develop the level(s) and a
description of why the level indicates proper operation of the control
device shall be provided in the Precompliance report. The procedures
specified in this section have not been approved by the Administrator
and determination of the parametric monitoring level using these
procedures is subject to review and approval by the Administrator.
(iii) Parameters for control devices controlling batch process
vents. For devices controlling batch process vents alone or in
combination with other streams, the parameter level(s) shall be
established in accordance with paragraph (b)(3)(iii)(A) or (B) of this
section.
(A) If more than one batch emission episode has been selected to be
controlled, a single level for the batch process(es) shall be determined
from the initial compliance demonstration.
(B) Instead of establishing a single level for the batch
process(es), as described in paragraph (b)(3)(iii)(A) of this section,
an owner or operator may establish separate levels for each batch
emission episode, selected to be controlled. If separate monitoring
levels are established, the owner or operator must provide a record
indicating at what point in the daily schedule or log of processes
required to be recorded per the requirements of Sec. 63.1259(b)(9) the
parameter being monitored changes levels and must record at least one
reading of the new parameter level, even if the duration of monitoring
for the new parameter is less than 15-minutes.

TOC concentration and the outlet hydrogen halide and halogen
concentration every 15 minutes during the period in which the device is
functioning in achieving the HAP removal
[[Page 94]]
required by this subpart. A TOC monitor meeting the requirements of
Performance Specification 8 or 9 of appendix B of part 60 shall be
installed, calibrated, and maintained, according to Sec. 63.8. The owner
or operator need notmonitor the hydrogen halide and halogen
concentration if, based on process knowledge, the owner or operator
determines that the emission stream does not contain hydrogen halides or
halogens.

above the maximum value established during the initial compliance
demonstration.
(iii) Each loss of pilot flame for flares.
(7) Excursions. Excursions are defined by either of the two cases
listed in paragraphs (b)(7)(i) or (ii) of this section.
(i) When the period of control device operation is 4 hours or
greater in an operating day and monitoring data are insufficient to
constitute a valid hour of data, as defined in paragraph (b)(7)(iii) of
this section, for at least 75 percent of the operating hours.
(ii) When the period of control device operation is less than 4
hours in an operating day and more than one of the hours during the
period of operation does not constitute a valid hour of data due to
insufficient monitoring data.
(iii) Monitoring data are insufficient to constitute a valid hour of
data, as used in paragraphs (b)(7)(i) and (ii) of this section, if
measured values are unavailable for any of the required 15-minute
periods within the hour.
(8) Violations. Exceedances of parameters monitored according to the
provisions of paragraphs (b)(1)(ii) and (iv) through (ix) of this
section or excursions as defined by paragraphs (b)(7)(i) through (iii)

the temperature limit monitored according to the provisions of paragraph
(b)(1)(iii) of this section or exceedances of the outlet concentrations
monitored according to the provisions of paragraph (b)(1)(x) of this
section constitute violations of the emission limit according to
paragraphs (b)(8)(i), (ii), and (iv) of this section. Exceedances of the
outlet concentrations monitored according to the provisions of paragraph
(b)(5) of this section constitute violations of the emission limit
according to the provisions of paragraphs (b)(8)(iii) and (iv) of this
section.
(i) Except as provided in paragraph (b)(8)(iv) of this section, for
episodes occurring more than once per day, exceedances of established
parameter limits or excursions will result in no more than one violation
per operating day for each monitored item of equipment utilized in the
process.
(ii) Except as provided in paragraph (b)(8)(iv) of this section, for
control devices used for more than one process in the course of an
operating day, exceedances or excursions will result in no more than one
violation per operating day, per control device, for each process for
which the control device is in service.
(iii) Except as provided in paragraph (b)(8)(iv) of this section,
exceedances of the 20 ppmv TOC outlet emission limit, averaged over the
operating day, will result in no more than one violation per day per

affected source complying with the provisions of Sec. 63.1254(a)(1)
shall demonstrate continuous compliance with the 2,000 lb/yr emission
limits by calculating daily a 365-day rolling summation of emissions.
For owners and operators opting
[[Page 95]]
to switch compliance strategy from the 93 percent control requirement to
the 2,000 lb/yr compliance method, as decribed in Sec. 63.1254(a), the

Subpart HHH--National Emission Standards for Hazardous Air Pollutants
From Natural Gas Transmission and Storage Facilities
Source: 64 FR 32648, June 17, 1999, unless otherwise noted.
Sec. 63.1270 Applicability and designation of affected source.
(a) This subpart applies to owners and operators of natural gas
transmission and storage facilities that transport or store natural gas
prior to entering the pipeline to a local distribution company or to a
final end user (if there is no local distribution company), and that are
major sources of hazardous air pollutants (HAP) emissions as determined
using the maximum natural gas throughput calculated in either paragraph
(a)(1) or (a)(2) of this section and paragraphs (a)(3) and (a)(4) of
this section. A compressor station that transports natural gas prior to
the point of custody transfer, or to a natural gas processing plant (if
present) is considered a part of the oil and natural gas production
source category. A facility that is determined to be an area source,
based on emission estimates using the maximum natural gas throughput
calculated as specified in paragraph (a)(1) or (a)(2) of this section,
but subsequently increases emissions or potential to emit above the
major source levels (without first obtaining and complying with other
limitations that keep its potential to emit HAP below major source
levels, becomes a major source and must comply thereafter with all
applicable provisions of this subpart starting on the applicable
compliance date specified in paragraph (d) of this section. Nothing in
this paragraph is intended to preclude a source from limiting its
potential to emit through other appropriate mechanisms that may be
available through the permitting authority.
(1) Facilities that store natural gas or facilities that transport
and store natural gas shall determine major source status using the
maximum annual facility natural gas throughput calculated according to
paragraphs
[[Page 114]]
(a)(1)(i) through (a)(1)(iv) of this section.
(i) The owner or operator shall determine the number of hours to
complete the storage cycle for the facility. The storage cycle is the
number of hours for the injection cycle, calculated according to the
equation in paragraph (a)(1)(i)(A) of this section, plus the number of
hours for the withdrawal cycle, calculated according to the equation in
paragraph (a)(1)(i)(B) of this section.
(A) The hours for the facility injection cycle are determined
according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.005
Where:
IC = Facility injection cycle in hours/cycle.
WGC = Working gas capacity in cubic meters. The working gas capacity is
defined as the maximum storage capacity minus the FERC cushion
(as defined in Sec. 63.1271).
IRmax = Maximum facility injection rate in cubic meters per
hour.
(B) The hours for the facility withdrawal cycle are determined
according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.006
Where:
WC = Facility withdrawal cycle, hours/cycle.
WGC = Working gas capacity, cubic meters. The working gas capacity is
defined as the maximum storage capacity minus the FERC cushion
(as defined in Sec. 63.1271) and shall be the same value as
used in paragraph (a)(1)(i)(A) of this section.
WRmax = Maximum facility withdrawal rate in cubic meters per
hour.
(ii) The owner or operator shall calculate the number of storage
cycles for the facility per year according to the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JN99.007
Where:
Cycle = Number of storage cycles for the facility per year.
IC = Number of hours for a facility injection cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(A) of this section.
WC = Number of hours for a facility withdrawal cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(B) of this section.
(iii) The owner or operator shall calculate the facilitywide maximum
annual glycol dehydration unit hours of operation based on the following
equation:
Operation = Cycles x WC
Where:
Operation = Facilitywide maximum annual glycol dehydration unit hours of
operation (hr/yr).
Cycles = Number of storage cycles for the facility per year, as
calculated in paragraph (a)(1)(ii) of this section.
WC = Number of hours for a facility withdrawal cycle, hours/cycle, as
calculated in paragraph (a)(1)(i)(B) of this section.
(iv) The owner or operator shall calculate the maximum facilitywide
natural gas throughput based on the following equation:
Throughput = Operation x WRmax
Where:
Throughput = Maximum facilitywide natural gas throughput in cubic meters
per year.
Operation = Maximum facilitywide annual glycol dehydration unit hours of
operation in hours per year, as calculated in paragraph
(a)(1)(iii) of this section.
WRmax = Maximum facility withdrawal rate in cubic meters per
hour.
(2) Facilities that only transport natural gas shall calculate the
maximum natural gas throughput as the highest annual natural gas
throughput over the 5 years prior to June 17, 1999, multiplied by a
factor of 1.2.
(3) The owner or operator shall maintain records of the annual
facility natural gas throughput each year and upon request, submit such
records to the Administrator. If the facility annual natural gas
throughput increases above the maximum natural gas throughput calculated
in paragraph (a)(1) or (a)(2) of this section, the maximum natural gas
throughput must be recalculated using the higher throughput multiplied
by a factor of 1.2.
(4) The owner or operator shall determine the maximum values for
other parameters used to calculate potential emissions as the maximum
over the same period for which maximum throughput is determined as
specified in paragraph (a)(1) or (a)(2) of this section. These
parameters shall be based
[[Page 115]]
on an annual average or the highest single measured value.
(b) The affected source is each glycol dehydration unit.
(c) The owner or operator of a facility that does not contain an
affected source, as specified in paragraph (b) of this section, is not
subject to the requirements of this subpart.
(d) The owner or operator of each affected source shall achieve
compliance with the provisions of this subpart by the following dates:
(1) The owner or operator of an affected source, the construction or
reconstruction of which commenced before February 6, 1998, shall achieve
compliance with this provisions of the subpart no later than June 17,
2002 except as provided for in Sec. 63.6(i). The owner or operator of an
area source, the construction or reconstruction of which commenced
before February 6, 1998, that increases its emissions of (or its
potential to emit) HAP such that the source becomes a major source that
is subject to this subpart shall comply with this subpart 3 years after
becoming a major source.
(2) The owner or operator of an affected source, the construction or
reconstruction of which commences on or after February 6, 1998, shall
achieve compliance with the provisions of this subpart immediately upon
initial startup or June 17, 1999, whichever date is later. Area sources,
the construction or reconstruction of which commences on or after
February 6, 1998, that become major sources shall comply with the
provisions of this standard immediately upon becoming a major source.
(e) An owner or operator of an affected source that is a major
source or is located at a major source and is subject to the provisions
of this subpart is also subject to 40 CFR part 70 or part 71 permitting
requirements.
(f) Exemptions. A facility with a facilitywide actual annual average
natural gas throughput less than 28.3 thousand standard cubic meters per
day, where glycol dehydration units are the only HAP emission source, is
not subject to the requirements of this subpart. Records shall be
maintained as required in Sec. 63.10(b)(3).
Sec. 63.1271 Definitions.
All terms used in this subpart shall have the meaning given to them
in the Clean Air Act, subpart A of this part (General Provisions), and
in this section. If the same term is defined in subpart A and in this
section, it shall have the meaning given in this section for purposes of
this subpart.
Boiler means an enclosed device using controlled flame combustion
and having the primary purpose of recovering and exporting thermal
energy in the form of steam or hot water. Boiler also means any
industrial furnace as defined in 40 CFR 260.10.
Closed-vent system means a system that is not open to the atmosphere
and is composed of piping, ductwork, connections, and if necessary, flow
inducing devices that transport gas or vapor from an emission point to
one or more control devices. If gas or vapor from regulated equipment is
routed to a process (e.g., to a fuel gas system), the conveyance system
shall not be considered a closed-vent system and is not subject to
closed-vent system standards.
Combustion device means an individual unit of equipment, such as a
flare, incinerator, process heater, or boiler, used for the combustion
of organic HAP emissions.
Compressor station means any permanent combination of compressors
that move natural gas at increased pressure from fields, in transmission
pipelines, or into storage.
Continuous recorder means a data recording device that either
records an instantaneous data value at least once every hour or records
hourly or more frequent block average values.
Control device means any equipment used for recovering or oxidizing
HAP or volatile organic compounds (VOC) vapors. Such equipment includes,
but is not limited to, absorbers, carbon adsorbers, condensers,
incinerators, flares, boilers, and process heaters. For the purposes of
this subpart, if gas or vapor from regulated equipment is used, reused
(i.e., injected into the flame zone of a combustion device), returned
back to the process, or sold,
[[Page 116]]
then the recovery system used, including piping, connections, and flow
inducing devices, is not considered to be control devices or closed-vent
systems.
Custody transfer means the transfer of hydrocarbon liquids or
natural gas:
(1) After processing and/or treatment in the producing operations;
or
(2) From storage vessels or automatic transfer facilities, or other
equipment, including product loading racks, to pipelines or any other
forms of transportation.
Facility means any grouping of equipment where natural gas is
processed, compressed, or stored prior to entering a pipeline to a local
distribution company or (if there is no local distribution company) to a
final end user. Examples of a facility for this source category are: an
underground natural gas storage operation; or a natural gas compressor
station that receives natural gas via pipeline, from an underground
natural gas storage operation, or from a natural gas processing plant.
The emission points associated with these phases include, but are not
limited to, process vents. Processes that may have vents include, but
are not limited to, dehydration and compressor station engines.
Facility, for the purpose of a major source determination, means
natural gas transmission and storage equipment that is located inside
the boundaries of an individual surface site (as defined in this
section) and is connected by ancillary equipment, such as gas flow lines
or power lines. Equipment that is part of a facility will typically be
located within close proximity to other equipment located at the same
facility. Natural gas transmission and storage equipment or groupings of
equipment located on different gas leases, mineral fee tracts, lease
tracts, subsurface unit areas, surface fee tracts, or surface lease
tracts shall not be considered part of the same facility.
Federal Energy Regulatory Commission Cushion or FERC Cushion means

or flash tank.
Glycol dehydration unit means a device in which a liquid glycol
(including, but not limited to, ethylene glycol, diethylene glycol, or
triethylene glycol) absorbent directly contacts a natural gas stream and
absorbs water in a contact tower or absorption column (absorber). The

constituents from the natural gas and becomes ``rich'' glycol. This
glycol is then regenerated in the glycol dehydration unit reboiler. The
``lean'' glycol is then recycled.
Glycol dehydration unit baseline operations means operations
representative of the glycol dehydration unit operations as of June 17,
1999. For the purposes of this subpart, for determining the percentage

Incinerator means an enclosed combustion device that is used for
destroying organic compounds. Auxiliary fuel may be used to heat waste
gas to combustion temperatures. Any energy recovery section is not
physically formed into one manufactured or assembled unit with the
combustion section; rather, the energy recovery section is a separate
section following the combustion section and the two are joined by ducts
or connections carrying flue gas. The above energy recovery section
limitation does not apply to an energy recovery section used solely to
preheat the incoming vent stream or combustion air.

established for a control device or process parameter which, if achieved
by itself or in combination with one or more other operating parameter
values, indicates that an owner or operator has complied with an
applicable operating parameter limitation, over the appropriate
averaging period as specified in Sec. 63.1282 (e) and (f).

Sec. 63.1272 Startups, shutdowns, and malfunctions.
(a) The provisions set forth in this subpart shall apply at all
times except during startups or shutdowns, during malfunctions, and
during periods of non-operation of the affected sources (or specific
portion thereof) resulting in cessation of the emissions to which this
subpart applies. However, during the startup, shutdown, malfunction, or
period of non-operation of one portion of an affected source, all
emission points which can comply with the specific provisions to which
they are subject must do so during the startup, shutdown, malfunction,
or period of non-operation.
(b) The owner or operator shall not shut down items of equipment
that are required or utilized for compliance with the provisions of this
subpart during times when emissions are being routed to such items of
equipment, if the shutdown would contravene requirements of this subpart
applicable to such items of equipment. This paragraph does not apply if
the item of equipment is malfunctioning, or if the owner or operator
must shut down the equipment to avoid damage due to a contemporaneous
startup, shutdown, or malfunction of the affected source or a portion
thereof.
(c) During startups, shutdowns, and malfunctions when the
requirements of this subpart do not apply pursuant to paragraphs (a) and
(b) of this section, the owner or operator shall implement, to the
extent reasonably available, measures to prevent or minimize excess
emissions to the maximum extent practical. For purposes of this
paragraph, the term ``excess emissions'' means emissions in excess of
those that would have occurred if there were no startup, shutdown, or
malfunction, and
[[Page 119]]
the owner or operator complied with the relevant provisions of this
subpart. The measures to be taken shall be identified in the applicable
startup, shutdown, and malfunction plan, and may include, but are not
limited to, air pollution control technologies, recovery technologies,
work practices, pollution prevention, monitoring, and/or changes in the
manner of operation of the source. Back-up control devices are not
required, but may be used if available.
(d) The owner or operator shall prepare a startup, shutdown, or
malfunction plan as required in Sec. 63.6(e)(3) except that the plan is
not required to be incorporated by reference into the source's title V
permit as specified in Sec. 63.6(e)(3)(i). Instead, the owner or
operator shall keep the plan on record as required by
Sec. 63.6(e)(3)(v). The failure of the plan to adequately minimize
emissions during the startup, shutdown, or malfunction does not shield
an owner or operator from enforcement actions.

part 60, appendix A.
(6)(i) Except as provided in paragraph (b)(6)(i) of this section,
the detection instrument shall meet the performance criteria of Method
21 of 40 CFR part 60, appendix A, except the instrument response factor
criteria in section 3.1.2(a) of Method 21 shall be for the average

calculated on an inert-free basis.
(ii) If no instrument is available at the facility that will meet
the performance criteria specified in paragraph (b)(6)(i) of this
section, the instrument readings may be adjusted by multiplying by the
average response factor of the process fluid, calculated on an inert-
free basis as described in paragraph (b)(6)(i) of this section.

section.
(ii) If an owner or operator chooses to adjust the detection
instrument readings for the background organic concentration level, the
value of the arithmetic difference between the maximum organic
concentration value measured by the instrument and the background
organic concentration value as determined in paragraph (b)(5) of this
section is compared with the applicable value for the potential leak
interface as specified in paragraph (b)(8) of this section.
(8) A potential leak interface is determined to operate with no
detectable organic emissions if the organic concentration value
determined in paragraph (b)(7) is less than 500 parts per million by

that has less than 30 days of data for determining average HAP emission
reduction, shall calculate the cumulative average at the end of the
calendar year, each year, until 30 days of condenser operating data are
accumulated.

in accordance with the requirements of Sec. 63.1282(d)(4)(i)(D) to
demonstrate that the condenser achieves the applicable performance
requirements specified in Sec. 63.1281(d)(1) or (e)(3)(ii), then the
condenser performance curve shall be based on the condenser design
analysis and may be supplemented by the control device manufacturer's
recommendations.
(C) As an alternative to paragraphs (d)(5)(ii)(A) and (B) of this
section, the owner or operator may elect to use the procedures
documented in the GRI report entitled, ``Atmospheric Rich/Lean Method
for Determining Glycol Dehydrator Emissions'' (GRI-95/0368.1) as inputs
for the model GRI-GLYCalcTM, Version 3.0 or higher, to
generate a condenser performance curve.
(6) An excursion for a given control device is determined to have
occurred when the monitoring data or lack of monitoring data result in
any one of the criteria specified in paragraphs (d)(6)(i) through
(d)(6)(iv) of this section being met. When multiple operating parameters
are monitored for the same control device and during the same operating
day, and more than one of these operating parameters meets an excursion
criterion specified in paragraphs (d)(6)(i) through (d)(6)(iv) of this
section, then a single excursion is determined to have occurred for the
control device for that operating day.
(i) An excursion occurs when the daily average value of a monitored
operating parameter is less than the minimum operating parameter limit
(or, if applicable, greater than the maximum operating parameter limit)
established for the operating parameter in accordance with the
requirements of paragraph (d)(5)(i) of this section.
(ii) An excursion occurs when average condenser efficiency
calculated according to the requirements specified in
Sec. 63.1282(f)(2)(iii) is less than 95.0 percent, as specified in
Sec. 63.1282(f)(3).
(iii) An excursion occurs when the monitoring data are not available
for at least 75 percent of the operating hours.
(iv) If the closed-vent system contains one or more bypass devices
that could be used to divert all or a portion of the gases, vapors, or
fumes from entering the control device, an excursion occurs when:
(A) For each bypass line subject to Sec. 63.1281(c)(3)(i)(A) the
flow indicator indicates that flow has been detected and that the stream
has been diverted away from the control device to the atmosphere.
(B) For each bypass line subject to Sec. 63.1281(c)(3)(i)(B), if the
seal or closure mechanism has been broken, the bypass line valve
position has changed, the key for the lock-and-key type lock has been
checked out, or the car-seal has broken.
(7) For each excursion, except as provided for in paragraph (d)(8)
of this section, the owner or operator shall be deemed to have failed to
have applied control in a manner that achieves the required operating
parameter limits. Failure to achieve the required operating parameter
limits is a violation of this standard.
(8) An excursion is not a violation of the operating parameter limit
as specified in paragraphs (d)(8)(i) and (d)(8)(ii) of this section.
(i) An excursion does not count toward the number of excused
excursions allowed under paragraph (d)(8)(ii) of this section when the
excursion occurs during any one of the following periods:
[[Page 133]]
(A) During a period of startup, shutdown, or malfunction when the
affected facility is operated during such period in accordance with the
facility's startup, shutdown, and malfunction plan; or
(B) During periods of non-operation of the unit or the process that
is vented to the control device (resulting in cessation of HAP emissions
to which the monitoring applies).
(ii) For each control device, or combinations of control devices,
installed on the same HAP emissions unit, one excused excursion is
allowed per semiannual period for any reason. The initial semiannual
period is the 6-month reporting period addressed by the first Periodic
Report submitted by the owner or operator in accordance with
Sec. 63.1285(e) of this subpart.
(9) Nothing in paragraphs (d)(1) through (d)(8) of this section
shall be construed to allow or excuse a monitoring parameter excursion
caused by any activity that violates other applicable provisions of this
subpart.

Sec. 63.1292 Definitions.
All terms used in this subpart shall have the meaning given them in
the Act, in subpart A of this part, and in this section. If a term is
defined in subpart A and in this section, it shall have the meaning
given in this section for purposes of this subpart.
Auxiliary blowing agent, or ABA, means a low-boiling point liquid
added to assist foaming by generating gas beyond that resulting from the
isocyanate-water reaction.
Breakthrough means that point in the adsorption step when the mass
transfer zone (i.e., the section of the carbon bed where the HAP is
removed from the carrier gas stream) first reaches the carbon bed outlet
as the mass transfer zone moves down the bed in the direction of flow.
The breakthrough point is characterized by the beginning of a sharp
increase in the outlet HAP or organic compound concentration.
Calibrate means to verify the accuracy of a measurement device
against a known standard. For the purpose of this subpart, there are two
levels of calibration. The initial calibration includes the verification
of the accuracy of the device over the entire operating range of the
device. Subsequent calibrations can be conducted for a point or several
points in a limited range of operation that represents the most common
operation of the device.
Canned motor pump means a pump with interconnected cavity housings,
motor rotors, and pump casing. In a canned motor pump, the motor
bearings run in the process liquid and all seals are eliminated.
Carbon adsorption system means a system consisting of a tank or
container that contains a specific quantity of activated carbon. For the
purposes of this subaprt, a carbon adsorption system is used as a
control device for storage vessels. Typically, the spent carbon bed does
not undergo regeneration, but is replaced.
Connector means flanged, screwed, or other joined fittings used to
connect two pipe lines or a pipe line and a piece of equipment. A common
connector is a flange. Joined fittings welded completely around the
circumference of the interface are not considered to be connectors for
the purposes of this subpart.
Cured foam means flexible polyurethane foam with fully developed
physical properties. A period of 12 to 24 hours from pour is typically
required to completely cure foam, although mechanical or other devices
are sometimes used to accelerate the curing process.
Curing area means the area in a slabstock foam production facility
where foam buns are allowed to fully develop physical properties.
Diaphragm pump means a pump where the driving member is a flexible
diaphragm made of metal, rubber, or plastic. In a diaphragm pump, there
is no packing or seals that are exposed to the process liquid.
Diisocyanate means a compound containing two isocyanate groups per
molecule. The most common diisocyanate compounds used in the flexible
polyurethane foam industry are toluene diisocyanate (TDI) and methylene
diphenyl diisocyanate (MDI).
Flexible polyurethane foam means a flexible cellular polymer
containing urea and carbamate linkages in the chain backbone produced by
reacting a diisocyanate, polyol, and water. Flexible polyurethane foams
are open-celled, permit the passage of air through the foam, and possess
the strength and flexibility to allow repeated distortion or compression
under stress with essentially complete recovery upon removal of the
stress.
Flexible polyurethane foam process means the equipment used to
produce a flexible polyurethane foam product. For the purpose of this
subpart, the flexible polyurethane foam process includes raw material
storage; production equipment and associated piping, ductwork, etc.; and
curing and storage areas.
Foam fabrication process means an operation for cutting or bonding
flexible polyurethane foam pieces together or to other substrates.
Grade of foam means foam with a distinct combination of indentation
force deflection (IFD) and density values.
HAP ABA means methylene chloride, or any other HAP compound used as
an auxiliary blowing agent.
[[Page 144]]
HAP-based means to contain 5 percent (by weight) or more of HAP.
This applies to equipment cleaners (and mixhead flushes) and mold
release agents. The concentration of HAP may be determined using EPA
test method 18, material safety data sheets, or engineering
calculations.
High-pressure mixhead means a mixhead where mixing is achieved by
impingement of the high pressure streams within the mixhead.
Indentation Force Deflection (IFD) means a measure of the load
bearing capacity of flexible polyurethane foam. IFD is generally
measured as the force (in pounds) required to compress a 50 square inch
circular indentor foot into a four inch thick sample, typically 15
inches square or larger, to 25 percent of the sample's initial height.
In diisocyanate service means a piece of equipment that contains or
contacts a diisocyanate.
In HAP ABA service means a piece of equipment that contains or
contacts a HAP ABA.
Initial startup means the first time a new or reconstructed affected
source begins production of flexible polyurethane foam.
Isocyanate means a reactive chemical grouping composed of a nitrogen
atom bonded to a carbon atom bonded to an oxygen atom; or a chemical
compound, usually organic, containing one or more isocyanate groups.
Magnetic drive pump means a pump where an externally-mounted magnet
coupled to the pump motor drives the impeller in the pump casing. In a
magnetic drive pump, no seals contact the process fluid.
Metering pump means a pump used to deliver reactants, ABA, or
additives to the mixhead.
Mixhead means a device that mixes two or more component streams
before dispensing foam producing mixture to the desired container.
Molded flexible polyurethane foam means a flexible polyurethane foam
that is produced by shooting the foam mixture into a mold of the desired
shape and size.
Mold release agent means any material which, when applied to the
mold surface, serves to prevent sticking of the foam part to the mold.
Plant site means all contiguous or adjoining property that is under
common control, including properties that are separated only by a road
or other public right-of-way. Common control includes properties that
are owned, leased, or otherwise operated by the same entity, parent
entity, subsidiary, or any combination thereof.
Polyol, for the purpose of this subpart, means a polyether or
polyester polymer with more than one reactive hydroxyl group attached to
the molecule.
Rebond foam means the foam resulting from a process of adhering
small particles of foam (usually scrap or recycled foam) together to
make a usable cushioning product. Various adhesives and bonding
processes are used. A typical application for rebond foam is for carpet
underlay.
Rebond foam process means the equipment used to produce a rebond
foam product. For the purpose of this subpart, the rebond foam process
includes raw material storage; production equipment and associated
piping, ductwork, etc.; and curing and storage areas.
Reconstructed source means an affected source undergoing
reconstruction, as defined in subpart A. For the purposes of this
subpart, process modifications made to reduce HAP ABA emissions to meet
the existing source requirements of this subpart shall not be counted in
determining whether or not a change or replacement meets the definition
of reconstruction.
Recovery device means an individual unit of equipment capable of and
used for the purpose of recovering chemicals for use, reuse, or sale.
Recovery devices include, but are not limited to, carbon adsorbers,
absorbers, and condensers.
Research and development process means a laboratory or pilot plant
operation whose primary purpose is to conduct research and development
into new processes and products, where the operations are under the
close supervision of technically trained personnel, and which is not
engaged in the manufacture of products for commercial sale except in a
de minimis manner.
Run of foam means a continuous production of foam, which may consist
of several grades of foam.
[[Page 145]]

portions of the flexible polyurethane foam process from the mixhead to
the point in the process where the foam is completely cured.
Storage vessel means a tank or other vessel that is used to store
diisocyanate or HAP ABA for use in the production of flexible
polyurethane foam. Storage vessels do not include vessels with
capacities smaller than 38 cubic meters (or 10,000 gallons).

Sec. 63.1297 Standards for slabstock flexible polyurethane foam production--HAP ABA emissions from the production line.
(a) Each owner or operator of a new or existing slabstock affected
source complying with the emission point specific limitation option
provided in Sec. 63.1293(a)(1) shall control HAP ABA emissions from the
slabstock polyurethane foam production line in accordance with the
provisions in this section. Compliance shall be determined on a rolling
annual basis as described in paragraph (a)(1) of this section. As an
alternative, the owner or operator can determine compliance on a monthly
basis, as described in paragraph (a)(2) of this section.
(1) Rolling annual compliance. In determining compliance on a
rolling annual basis, actual HAP ABA emissions shall be compared to
allowable HAP ABA emissions for each consecutive 12-month period. The
allowable HAP ABA emission level shall be calculated based on the
production for the 12-month period, resulting in a potentially different
allowable level for each 12-month period. Compliance shall be determined
each month for the previous 12-month period. The compliance requirements
are provided in paragraph (b) of this section.
(2) Monthly compliance alternative. As an alternative to determining
compliance on a rolling annual basis, an owner or operator can determine
compliance by comparing actual HAP ABA emissions to allowable HAP ABA
emissions for each month. The allowable HAP ABA emission level shall be
calculated based on the production for the month, resulting in a
potentially different allowable level each month. The requirements for
this monthly compliance alternative are provided in paragraph (c) of
this section.
(3) Each owner or operator electing to change between the compliance
methods described under paragraphs (a)(1) and (a)(2) of this section
shall notify the Administrator no later than 180 calendar days prior to
the change.
(b) Rolling annual compliance. At each slabstock foam production
source complying with the rolling annual compliance provisions described
in paragraph (a)(1) of this section, actual HAP ABA emissions shall not
exceed the allowable HAP ABA emission level for a consecutive 12-month
period. The actual HAP ABA emission level for a consecutive 12-month
period shall be determined using the procedures in paragraph (b)(1) of
this section, and the allowable HAP ABA emission level for the
corresponding 12-month period shall be calculated in accordance with
paragraph (b)(2) of this section.
(1) The actual HAP ABA emissions for a 12-month period shall be
calculated as the sum of actual monthly HAP ABA emissions for each of
the individual 12 months in the period. Actual monthly HAP ABA emissions
shall be equal to the amount of HAP ABA added to the slabstock foam
production line at the mixhead, determined in accordance with
Sec. 63.1303(b), unless a recovery device is used. Slabstock foam
production sources using recovery devices to reduce HAP ABA emissions
shall determine actual monthly HAP ABA emissions using the procedures in
paragraph (e) of this section.
(2) The allowable HAP ABA emissions for a consecutive 12-month
period shall be calculated as the sum of allowable monthly HAP ABA
emissions for each of the individual 12 months in the period. Allowable

this section. Compliance shall be determined on a rolling annual basis
in accordance with paragraph (a) of this section. As an alternative, the
owner or operator can determine compliance monthly, as described in
paragraph (b) of this section.
(a) Rolling annual compliance. Under the rolling annual compliance
provisions, actual source-wide HAP ABA storage and equipment leak
emissions, HAP ABA emissions from the production line, and equipment
cleaning HAP emissions are compared to allowable source-wide emissions
for each consecutive 12-month period. The allowable source-wide HAP
emission level is calculated based on the production for the 12-month
period, resulting in a potentially different allowable level for each
12-month period. While compliance is on an annual basis, compliance
shall be determined monthly for the preceding 12-month period. The
actual source-wide HAP emission level for a consecutive 12-month period
shall be determined using the procedures in
[[Page 152]]
paragraphs (c)(1) through (4) of this section, unless a recovery device
is used. Slabstock foam production sources using recovery devices shall
determine actual source-wide HAP emissions in accordance with paragraph
(e) of this section. The allowable HAP emission level for a consecutive
12-month period shall be determined using the procedures in paragraph
(d) of this section.
(b) Monthly compliance alternative. As an alternative to determining
compliance on a rolling annual basis, an owner or operator can determine
compliance by comparing actual HAP emissions to allowable HAP emissions
for each month. The allowable source-wide emission level is calculated
based on the production for the month, resulting in a potentially
different allowable level each month. The actual monthly emission level
shall be determined using the procedures in paragraphs (c)(1) through

Sec. 63.1304 Testing requirements.
Owners and operators of affected sources shall use the test methods
listed in this section, as applicable, to demonstrate compliance with
this subpart.
(a) Test method and procedures to determine equipment leaks.
Monitoring, as required under Sec. 63.1296, shall comply with the
following requirements:
(1) Monitoring shall comply with Method 21 of 40 CFR part 60,
appendix A.
(2) The detection instrument shall meet the performance criteria of
Method 21 of 40 CFR part 60, appendix A, except that the instrument
response factor criteria in section 3.1.2(a) of Method 21 shall be for
the average composition of the source fluid, rather than for each
individual VOC in the stream. For source streams that contain nitrogen,
air, or other inerts which are not HAP or VOC, the average stream
response factor shall be calculated on an inert-free basis. The response
factor may be determined at any concentration for which monitoring for
leaks will be conducted.
(3) The instrument shall be calibrated before use on each day of its
use by the procedures specified in Method 21 of 40 CFR part 60, appendix
A.
(4) Calibration gases shall be:
(i) Zero air (less than 10 ppm of hydrocarbon in air); and
(ii) A mixture of methane and air at a concentration of
approximately, 1,000 ppm for all transfer pumps; and 500 ppm for all
other equipment, except as provided in paragraph (a)(4)(iii) of this
section.
(iii) The instrument may be calibrated at a higher methane
concentration (up to 2,000 ppm) than the leak definition concentration
for a specific piece of equipment for monitoring that piece of
equipment. If the monitoring instrument's design allows for multiple
calibration gas concentrations, then the lower concentration calibration
gas shall be no higher than 2,000 ppm methane and the higher
concentration calibration gas shall be no higher than 10,000 ppm
methane.
(5) Monitoring shall be performed when the equipment is in HAP ABA
service, in use with an acceptable surrogate volatile organic compound
which is not a HAP ABA, or is in use with any other detectable gas or
vapor.
(6) If no instrument is available onsite that will meet the
performance criteria specified in section 3.1.2(a) of Method 21 of 40
CFR Part 60, appendix A, the readings from an available instrument may
be adjusted by multiplying by the average response factor for the
stream.
(b) Test method to determine foam properties. The IFD and density of
each grade of foam produced during each run of foam shall be determined
using ASTM D3574-91, Standard Test Methods for Flexible Cellular
Materials--Slab, Bonded, and Molded (incorporation by reference--see
Sec. 63.14), using a sample of foam cut from the center of the foam bun.
The maximum sample size for which the IFD and density is determined
shall not be larger than 24 inches by 24 inches by 4 inches. For grades
of foam where the owner or operator has designated the HAP ABA
formulation limitation as zero, the owner or operator is not required to
determine the IFD and density in accordance with this paragraph.

Subpart JJJ--National Emission Standards for Hazardous Air Pollutant
Emissions: Group IV Polymers and Resins
Source: 61 FR 48229, Sept. 12, 1996, unless otherwise noted.
Sec. 63.1310 Applicability and designation of affected sources.
(a) Definition of affected source. The provisions of this subpart
apply to each affected source. An affected source is either an existing
affected source or a new affected source. Existing affected source is
defined in paragraph (a)(6) of this section, and new affected source is
defined in paragraph (a)(7) of this section. The affected source also
includes the emission points and equipment specified in paragraphs
(a)(1) through (a)(5) of this section that are associated with each
group of TPPU.
(1) Each wastewater stream.
(2) Each wastewater operation.
(3) Each heat exchange system.
(4) Each process contact cooling tower used in the manufacture of
PET that is associated with a new affected source.
(5) Each process contact cooling tower used in the manufacture of
PET using a continuous terephthalic acid high viscosity multiple end
finisher process that is associated with an existing affected source.
(6) Except as specified in paragraphs (b) through (d) of this
section, an existing affected source is defined as each group of one or
more thermoplastic product process units (TPPUs) that is not part of a
new affected source as defined in paragraph (a)(7) of this section, that
is manufacturing the same primary product, where each TPPU uses as a
reactant, or uses as a process solvent, or produces as a by-product or
co-product any organic hazardous air pollutant (organic HAP), and that
is located at a plant site that is a major source.
(7) Except as specified in paragraphs (b) through (d) of this
section, a new affected source is defined as a source meeting the
criteria of paragraph (a)(7)(i), (a)(7)(ii), or (a)(7)(iii) of this
section:
(i) At a plant site previously without HAP emissions points, each
group of one or more TPPUs manufacturing the same primary product that
is part of a major source on which construction commenced after March
29, 1995;
(ii) A TPPU meeting the criteria in paragraph (i)(1)(i) of this
section; or
(iii) A reconstructed affected source meeting the criteria in
paragraph (i)(2)(i) of this section.
(b) TPPUs exempted from the affected source. For a TPPU to be
excluded from the designation of affected source due to the fact that it
does not use as a reactant, or use as a process solvent, or produce as a
by-product or co-product any organic HAP, the owner or operator shall
comply with the requirements of paragraph (b)(1) of this section and
shall comply with the requirements of paragraph (b)(2) of this section
if requested to do so by the Administrator.
(1) Retain information, data, and analysis used to document the
basis for the determination that the TPPU does not use as a reactant or
use as a process solvent, or manufacture as a by-product or a co-product
any organic HAP. Types of information that could document this
determination include, but are not limited to, records of chemicals
purchased for the process, analyses of process stream composition, or
engineering calculations.
(2) When requested by the Administrator, demonstrate that the TPPU
does not use as a reactant, or use as a process solvent, or manufacture
as a by-product or co-product any organic HAP.
(c) Emission points exempted from the affected source. The affected
source does not include the emission points listed in paragraphs (c)(1)
through (c)(6) of this section:
(1) Stormwater from segregated sewers;
(2) Water from fire-fighting and deluge systems in segregated
sewers;
(3) Spills;
(4) Water from safety showers;
(5) Vessels and equipment storing and/or handling material that
contain no organic HAP and/or organic HAP as impurities only; and
(6) Equipment that is intended to operate in organic HAP service for
less than 300 hours during the calendar year.
[[Page 174]]
(d) Processes exempted from the affected source. The processes
specified in paragraphs (d)(1) through (d)(5) of this section are
exempted from the affected source:
(1) Research and development facilities;
(2) Polymerization processes occurring in a mold;
(3) Processes which manufacture binder systems containing a
thermoplastic product for paints, coatings, or adhesives;
(4) Finishing processes including equipment such as compounding
units, spinning units, drawing units, extruding units, and other
finishing steps; and
(5) Solid state polymerization processes.
(e) Applicability determination of nonthermoplastic equipment
included in a TPPU producing a thermoplastic product. If a polymer that
is not subject to this subpart is produced within the equipment (i.e.,
collocated) making up a TPPU and at least 50 percent of said polymer is
used in the production of a thermoplastic product manufactured by said
TPPU, the unit operations involved in the production of said polymer are
considered part of the TPPU and are subject to this rule except as
specified in this paragraph (e). If said unit operations are subject to
another MACT standard regulating the same emission points, said unit
operations are not subject to this subpart.
(f) Primary product determination and applicability. The primary
product of a process unit shall be determined according to the
procedures specified in paragraphs (f)(1) through (f)(2) of this
section. Paragraphs (f)(3) through (f)(4) of this section describe
whether or not a process unit is subject to this subpart. Paragraphs
(f)(5) through (f)(7) of this section discuss compliance for those TPPUs
operated as flexible operation units, as specified in paragraph (f)(2)
of this section.
(1) If a process unit only manufactures one product, then that
product shall represent the primary product of the process unit.
(2) If a process unit is designed and operated as a flexible
operation unit, the primary product shall be determined as specified in
paragraphs (f)(2)(i) or (f)(2)(ii) of this section based on the
anticipated operations for the 5 years following September 12, 1996 for
existing affected sources and for the first 5 years after initial start-
up for new affected sources.
(i) If the flexible operation unit will manufacture one product for
the greatest operating time over the five year period, then that product
shall represent the primary product of the flexible operation unit.
(ii) If the flexible operation unit will manufacture multiple
products equally based on operating time, then the product with the
greatest production on a mass basis over the five year period shall
represent the primary product of the flexible operation unit.
(3) If the primary product of a process unit is a thermoplastic
product, then said process unit is considered a TPPU. If said TPPU meets
all the criteria of paragraph (a) of this section, it is either an
affected source or is part of an affected source comprised of other TPPU
subject to this rule at the same plant site with the same primary
product. The status of a process unit as a TPPU and as an affected
source or part of an affected source shall not change regardless of what
products are produced in the future by said TPPU, with the exception
noted in paragraph (f)(3)(i) of this section.
(i) If a process unit terminates the production of all thermoplastic
products and does not anticipate the production of any thermoplastic
product in the future, the process unit is no longer a TPPU and is not
subject to this rule after notification is made as specified in
paragraph (f)(3)(ii) of this section.
(ii) The owner or operator of a process unit that wishes to remove
the TPPU designation from the process unit, as specified in paragraph
(f)(3)(i) of this section, shall notify the Administrator. This
notification shall be accompanied by rationale for why it is anticipated
that no thermoplastic products will be produced in the process unit in
the future.
(iii) If a process unit meeting the criteria of paragraph (f)(3)(i)
of this section begins the production of a thermoplastic product in the
future, the owner or operator shall use the procedures in
[[Page 175]]
paragraph (f)(4)(i) of this section to determine if the process unit is
re-designated as a TPPU.
(4) If the primary product of a process unit is not a thermoplastic
product, then said process unit is not an affected source nor is it part
of any affected source subject to this rule. Said process unit is not
subject to this rule at any time, regardless of what product is being
produced. The status of a process unit as not being a TPPU, and
therefore not an affected source nor part of an affected source subject
to this subpart, shall not change regardless of what products are
produced in the future by said TPPU, with the exception noted in
paragraph (f)(4)(i) of this section.
(i) If, at any time beginning September 12, 2001, the owner or
operator determines that a thermoplastic product is the primary product
for the process unit based on actual production data for any preceding
consecutive five-year period, then the process unit shall be designated
as a TPPU. If said TPPU meets all the criteria of paragraph (a) of this
section and is not subject to another subpart of 40 CFR part 63, it is
either an affected source or part of an affected source and shall be
subject to this rule.
(ii) If a process unit meets the criteria of paragraph (f)(4)(i) of
this section, the owner or operator shall notify the Administrator
within 6 months of making this determination. The TPPU, as the entire
affected source or part of an affected source, shall be in compliance
with the provisions of this rule within 3 years from the date of such
notification.
(iii) If a process unit is re-designated as a TPPU but does not meet
all the criteria of paragraph (a) of this section, the owner or operator
shall notify the Administrator within 6 months of making this
determination. Said notification shall include documentation justifying
the TPPU's status as not being an affected source or not being part of
an affected source.
(5) Once the primary product of a process unit has been determined
to be a thermoplastic product and it has been determined that all the
criteria of paragraph (a) of this section are met for said TPPU, the
owner or operator of the affected source shall comply with the standards
for the primary product. Owners or operators of flexible operation units
shall comply with the standards for the primary product as specified in
either paragraph (f)(5)(i) or (f)(5)(ii) of this section, except as
specified in paragraph (f)(5)(iii) of this section.
(i) Each owner or operator shall determine the group status of each
emission point that is part of said flexible operation unit based on
emission point characteristics when the primary product is being
manufactured. Based on this finding, the owner or operator shall comply
with the applicable standards for the primary product for each emission
point, as appropriate, at all times, regardless of what product is being
produced.
(ii) Alternatively, each owner or operator shall determine the group
status of each emission point that is part of said flexible operation
unit based on the emission point characteristics when each product
produced by the flexible operation unit is manufactured, regardless of
whether said product is a thermoplastic product or not. Based on these
findings, the owner or operator shall comply with the applicable
standards for the primary product for each emission point, as
appropriate, regardless of what product is being produced.
Note: Under this scenario it is possible that the group status, and
therefore the requirement to achieve emission reductions, for an
emission point may change depending on the product being produced.
(iii) Whenever a flexible operation unit manufactures a product that
meets the criteria of paragraph (b) of this section (i.e., does not use
or produce any organic HAP), all activities associated with the
manufacture of said product shall be exempt from the requirements of
this rule, to include the operation and monitoring of control or
recovery devices.
(6) The determination of the primary product for a process unit, to
include the determination of applicability of this subpart to process
units that are designed and operated as flexible operation units, shall
be reported in the Notification of Compliance Status required by
Sec. 63.1335(e)(5) when the primary product is determined to be a
[[Page 176]]
thermoplastic product. The Notification of Compliance Status shall
include the information specified in either paragraph (f)(6)(i) or
(f)(6)(ii) of this section. If the primary product is determined to be
something other than a thermoplastic product, the owner or operator
shall retain information, data, and analysis used to document the basis
for the determination that the primary product is not a thermoplastic
product.
(i) If the TPPU manufactures only one thermoplastic product,
identification of said thermoplastic product.
(ii) If the TPPU is designed and operated as a flexible operation
unit, the information specified in paragraphs (f)(6)(ii)(A) through
(f)(6)(ii)(C) of this section, as appropriate.
(A) Identification of the primary product.
(B) Information concerning operating time and/or production mass for
each product that was used to make the determination of the primary
product under paragraph (f)(2)(i) or (f)(2)(ii) of this section.
(C) Identification of which compliance option, either paragraph
(f)(5)(i) or (f)(5)(ii) of this section, has been selected by the owner
or operator.
(7) To demonstrate compliance with the rule during those periods
when a flexible operation unit that is subject to this subpart is
producing a product other than a thermoplastic product or is producing a
thermoplastic product that is not the primary product, the owner or
operator shall comply with either paragraphs (f)(7)(i) through
(f)(7)(ii) or paragraph (f)(7)(iii) of this section.
(i) Establish parameter monitoring levels, as specified in
Sec. 63.1334, for those emission points designated as Group 1, as
appropriate.
(ii) Submit the parameter monitoring levels developed under
paragraph (f)(7)(i) of this section and the basis for them in the
Notification of Compliance Status report as specified in
Sec. 63.1335(e)(5).
(iii) Demonstrate that the parameter monitoring levels established
for the primary product are also appropriate for those periods when
products other than the primary product are being produced. Material
demonstrating this finding shall be submitted in the Notification of
Compliance Status report as specified in Sec. 63.1335(e)(5).
(g) Storage vessel ownership determination. The owner or operator
shall follow the procedures specified in paragraphs (g)(1) through
(g)(8) of this section to determine to which process unit a storage
vessel shall belong.
(1) If a storage vessel is already subject to another subpart of 40
CFR part 63 on September 12, 1996, said storage vessel shall belong to
the process unit subject to the other subpart.
(2) If a storage vessel is dedicated to a single process unit, the
storage vessel shall belong to that process unit.
(3) If a storage vessel is shared among process units, then the
storage vessel shall belong to that process unit located on the same
plant site as the storage vessel that has the greatest input into or
output from the storage vessel (i.e., said process unit has the
predominant use of the storage vessel).
(4) If predominant use cannot be determined for a storage vessel
that is shared among process units and if one of those process units is
a TPPU subject to this subpart, the storage vessel shall belong to said
TPPU.
(5) If predominant use cannot be determined for a storage vessel
that is shared among process units and if more than one of the process
units are TPPUs that have different primary products and that are
subject to this subpart, then the owner or operator shall assign the
storage vessel to any one of the said TPPUs.
(6) If the predominant use of a storage vessel varies from year to
year, then predominant use shall be determined based on the utilization
that occurred during the year preceding September 12, 1996 or based on
the expected utilization for the 5 years following September 12, 1996
for existing affected sources, whichever is more representative of the
expected operations for said storage vessel, and based on the first 5
years after initial start-up for new affected sources. The determination
of predominant use shall be reported in the Notification of Compliance
Status required by Sec. 63.1335(e)(5). If the predominant use
[[Page 177]]
changes, the redetermination of predominant use shall be reported in the
next Periodic Report.
(7) If the storage vessel begins receiving material from (or sending
material to) another process unit; or ceasing to receive material from
(or send material to) a process unit; or if the applicability of this
subpart to a storage vessel has been determined according to the
provisions of paragraphs (g)(1) through (g)(6) of this section and there
is a significant change in the use of the storage vessel that could
reasonably change the predominant use, the owner or operator shall
reevaluate the applicability of this subpart to the storage vessel.
(8) Where a storage vessel is located at a major source that
includes one or more process units which place material into, or receive
materials from the storage vessel, but the storage vessel is located in
a tank farm, the applicability of this subpart shall be determined
according to the provisions in paragraphs (g)(8)(i) through (g)(8)(iv)
of this section.
(i) The storage vessel may only be assigned to a process unit that
utilizes the storage vessel and does not have an intervening storage
vessel for that product (or raw materials, as appropriate). With respect
to any process unit, an intervening storage vessel means a storage
vessel connected by hard-piping to the process unit and to the storage
vessel in the tank farm so that product or raw material entering or
leaving the process unit flows into (or from) the intervening storage
vessel and does not flow directly into (or from) the storage vessel in
the tank farm.
(ii) If there is no process unit at the major source that meets the
criteria of paragraph (g)(8)(i) of this section with respect to a
storage vessel, this subpart does not apply to the storage vessel.
(iii) If there is only one process unit at the major source that
meets the criteria of paragraph (g)(8)(i) of this section with respect
to a storage vessel, the storage vessel shall be assigned to that
process unit.
(iv) If there are two or more process units at the major source that
meet the criteria of paragraph (g)(8)(i) of this section with respect to
a storage vessel, the storage vessel shall be assigned to one of those
process units according to the provisions of paragraph (g)(7) of this
section. The predominant use shall be determined among only those
thermoplastic product process units that meet the criteria of paragraph
(g)(8)(i) of this section.
(h) Recovery operation equipment ownership determination. The owner
or operator shall follow the procedures specified in paragraphs (h)(1)
through (h)(7) of this section to determine to which process unit
recovery operation equipment shall belong.
(1) If recovery operation equipment is already subject to another
subpart of 40 CFR part 63 on September 12, 1996, said recovery operation
equipment shall belong to the process unit subject to the other subpart.
(2) If recovery operation equipment is used exclusively by a single
process unit, the recovery operation shall belong to that process unit.
(3) If recovery operation equipment is shared among process units,
then the recovery operation equipment shall belong to that process unit
located on the same plant site as the recovery operation equipment that
has the greatest input into or output from the recovery operation
equipment (i.e., said process unit has the predominant use of the
recovery operation equipment).
(4) If predominant use cannot be determined for recovery operation
equipment that is shared among process units and if one of those process
units is a TPPU subject to this subpart, the recovery operation
equipment shall belong to said TPPU.
(5) If predominant use cannot be determined for recovery operation
equipment that is shared among process units and if more than one of the
process units are TPPUs that have different primary products and that
are subject to this subpart, then the owner or operator shall assign the
recovery operation equipment to any one of said TPPUs.
(6) If the predominant use of recovery operation equipment varies
from year to year, then predominant use shall be determined based on the
utilization that occurred during the year preceding September 12, 1996
or based on the expected utilization for the 5 years
[[Page 178]]
following September 12, 1996 for existing affected sources, whichever is
the more representative of the expected operations for said recovery
operations equipment, and based on the first 5 years after initial
start-up for new affected sources. This determination shall be reported
in the Notification of Compliance Status required by Sec. 63.1335(e)(5).
If the predominant use changes, the redetermination of predominant use
shall be reported in the next Periodic Report.
(7) If there is an unexpected change in the utilization of recovery
operation equipment that could reasonably change the predominant use,
the owner or operator shall redetermine to which process unit the
recovery operation belongs by reperforming the procedures specified in
paragraphs (h)(2) through (h)(6) of this section.
(i) Changes or additions to plant sites. The provisions of
paragraphs (i)(1) through (i)(4) of this section apply to owners or
operators that change or add to their plant site or affected source.
Paragraph (i)(5) of this section provides examples of what are and are
not considered process changes for purposes of paragraph (i) of this
section.
(1) Adding a TPPU to a plant site. The provisions of paragraphs
(i)(1)(i) through (i)(1)(ii) of this section apply to owners or
operators that add TPPUs to a plant site.
(i) If a TPPU is added to a plant site, said addition shall be a new
affected source and shall be subject to the requirements for a new
affected source in this subpart upon initial start-up or by September
12, 1996, whichever is later, if said addition meets the criteria
specified in paragraphs (i)(1)(i)(A) through (i)(1)(i)(B) and either
(i)(1)(i)(C) or (i)(1)(i)(D) of this section:
(A) Said addition meets the definition of construction in Sec. 63.2;
(B) Such construction commenced after March 29, 1995; and
(C) Said addition has the potential to emit 10 tons per year or more
of any HAP or 25 tons per year or more of any combination of HAP, and
the primary product of said addition is currently produced at the plant
site as the primary product of an affected source; or
(D) The primary product of said addition is not currently produced
at the plant site as the primary product of an affected source and the
plant site meets, or after the addition is completed will meet, the
definition of major source.
(ii) If a TPPU is added to a plant site, said addition shall be
subject to the requirements for an existing affected source in this
subpart upon initial start-up or by 3 years after September 12, 1996,
whichever is later, if said addition does not meet the criteria
specified in paragraph (i)(1)(i) of this section and the plant site
meets, or after the addition is completed will meet, the definition of
major source.
(2) Adding emission points or making process changes to existing
affected sources. The provisions of paragraphs (i)(2)(i) through
(i)(2)(ii) of this section apply to owners or operators that add
emission points or make process changes to an existing affected source.
(i) If any process change is made or emission point is added to an
existing affected source, or if a process change creating one or more
additional Group 1 emission point(s) is made to an existing affected
source, said affected source shall be a new affected source and shall be
subject to the requirements for a new affected source in this subpart
upon initial start-up or by September 12, 1996, whichever is later, if
said process change or addition meets the criteria specified in
paragraphs (i)(2)(i)(A) through (i)(2)(i)(B) of this section:
(A) Said process change or addition meets the definition of
reconstruction in Sec. 63.2; and
(B) Such reconstruction commenced after March 29, 1995.
(ii) If any process change is made or emission point is added to an
existing affected source, or if a process change creating one or more
additional Group 1 emission point(s) is made to an existing affected
source and said process change or addition does not meet the criteria
specified in paragraphs (i)(2)(i)(A) through (i)(2)(i)(B) of this
section, the resulting emission point(s) shall be subject to the
requirements for an existing affected source in this subpart. Said
emission point(s) shall be in compliance upon initial start-up or by
[[Page 179]]
3 years after September 12, 1996, whichever is later, unless the owner
or operator demonstrates to the Administrator that achieving compliance
will take longer than making said process change or addition. If this
demonstration is made to the Administrator's satisfaction, the owner or
operator shall follow the procedures in paragraphs (i)(2)(iii)(A)
through (i)(2)(iii)(C) of this section to establish a compliance date.
(iii) To establish a compliance date for an emission point or points
specified in paragraph (i)(2)(ii) of this section, the procedures
specified in paragraphs (i)(2)(iii)(A) through (i)(2)(iii)(C) of this
section shall be followed.
(A) The owner or operator shall submit to the Administrator for
approval a compliance schedule, along with a justification for the
schedule.
(B) The compliance schedule shall be submitted within 180 days after
the process change or addition is made or the information regarding said
change or addition is known to the owner or operator, unless the
compliance schedule has been previously submitted to the permitting
authority. The compliance schedule may be submitted in the next Periodic
Report if the process change or addition is made after the date the
Notification of Compliance Status report is due.
(C) The Administrator shall approve the compliance schedule or
request changes within 120 calendar days of receipt of the compliance
schedule and justification.
(3) Existing source requirements for Group 2 emission points that
become Group 1 emission points. If a process change or addition that
does not meet the criteria in paragraph (i)(1) or (i)(2) of this section
is made to an existing plant site or existing affected source, and the
change causes a Group 2 emission point to become a Group 1 emission
point, for said emission point, the owner or operator shall comply with
the requirements of this subpart for existing Group 1 emission points.
Compliance shall be achieved as expeditiously as practicable, but in no
event later than 3 years after said emission point becomes a Group 1
emission point.
(4) Existing source requirements for some emission points that
become subject to the requirements of subpart H of this part. If a
compressor becomes subject to Sec. 63.164, the owner or operator shall
be in compliance upon initial start-up or by 3 years after September 12,
1996, whichever is later, unless the owner or operator demonstrates to
the Administrator that achieving compliance will take longer than making
the change. If this demonstration is made to the Administrator's
satisfaction, the owner or operator shall follow the procedures in
paragraphs (i)(2)(iii)(A) through (i)(2)(iii)(C) of this section to
establish a compliance date.
(5) Determining what are and are not process changes. For purposes
of paragraph (i) of this section, examples of process changes include,
but are not limited to, changes in production capacity, feedstock type,
or catalyst type, or whenever there is a replacement, removal, or the
addition of recovery equipment. For purposes of paragraph (i) of this
section, process changes do not include: process upsets, unintentional
temporary process changes, and changes that are within the equipment
configuration and operating conditions documented in the Notification of
Compliance Status report required by Sec. 63.1335(e)(5).
(j) Applicability of this subpart except during periods of start-up,
shutdown, and malfunction. Each provision set forth in this subpart or
referred to in this subpart shall apply at all times except during
periods of start-up, shutdown, and malfunction if the start-up,
shutdown, or malfunction precludes the ability of a particular emission
point of an affected source to comply with one or more specific
provisions to which it is subject. Start-up, shutdown, and malfunction
is defined in Sec. 63.1312 for all emission points except equipment
leaks subject to subpart H of this part, which shall follow the
provisions for periods of start-up, malfunction, and process unit
shutdown, as defined in Sec. 63.161. Only then shall an emission point
not be required to comply with all applicable provisions of this
subpart.
[[Page 180]]
Sec. 63.1311 Compliance schedule and relationship to existing applicable rules.
(a) Affected sources are required to achieve compliance on or before
the dates specified in paragraphs (b) through (d) of this section.
Paragraph (e) of this section provides information on requesting
compliance extensions. Paragraphs (f) through (l) of this section
discuss the relationship of this subpart to subpart A of this part and
to other applicable rules. Where an override of another authority of the

(2) The requirements in Sec. 63.6(i)(8) through Sec. 63.6(i)(14)
shall govern the review and approval of requests for extensions of
compliance with this subpart.
(f) Table 1 of this subpart specifies the provisions of subpart A of
this part that apply and those that do not apply to owners and operators
of affected sources subject to this subpart.
(g)(1) After the compliance dates specified in this section, an
affected source subject to this subpart that is also subject to the
provisions of subpart I of this part, is required to comply only with
the provisions of this subpart. After the compliance dates specified in
this section, said affected source shall no longer be subject to subpart
I of this part.
(2) Said affected sources that elected to comply with subpart I of
this part through a quality improvement program, as specified in
Sec. 63.175 or Sec. 63.176 or both, may elect to continue these programs
without interruption as a means of complying with this subpart. In other
words, becoming subject to this subpart does not restart or reset the
``compliance clock'' as it relates to reduced burden earned through a
quality improvement program.
(h) After the compliance dates specified in this section, a storage
vessel that belongs to an affected source subject to this subpart that
is also subject to the provisions of 40 CFR part 60, subpart Kb, is
required to comply only with the provisions of this subpart. After the
compliance dates specified in this section, said storage vessel shall no
longer be subject to 40 CFR part 60, subpart Kb.
(i)(1) Except as provided in paragraph (i)(2) of this section, after
the compliance dates specified in this section, affected sources
producing PET using a continuous terephthalic acid process, producing
PET using a continuous dimethyl terephthalate process, or producing
polystyrene resin using a continuous process subject to this subpart
that are also subject to the provisions
[[Page 182]]
of 40 CFR part 60, subpart DDD, are required to comply only with the
provisions of this subpart. After the compliance dates specified in this
section, said sources shall no longer be subject to 40 CFR part 60,
subpart DDD.
(2) Existing affected sources producing PET using a continuous
terephthalic acid high viscosity multiple end finisher process shall
continue to be subject to 40 CFR 60.562-1(c)(2)(ii)(C). Once said

with the provisions of this subpart. After the compliance dates
specified in this section, said source shall no longer be subject to 40
CFR part 60, subpart VV.
(l) After the compliance dates specified in this section, a
distillation operation that belongs to an affected source subject to
this subpart that is also subject to the provisions of 40 CFR part 60,
subpart NNN, is required to comply only with the provisions of this
subpart. After the compliance dates specified in this section, said
distillation operation shall no longer be subject to 40 CFR part 60,
subpart NNN.
(m) All terms in this subpart that define a period of time for
completion of required tasks (e.g., weekly, monthly, quarterly, annual),
unless specified otherwise in the section or subsection that imposes the
requirement, refer to the standard calendar periods.
(1) Notwithstanding time periods specified in this subpart for
completion of required tasks, such time periods may be changed by mutual
agreement between the owner or operator and the Administrator, as
specified in subpart A of this part (e.g., a period could begin on the
compliance date or another date, rather than on the first day of the
standard calendar period). For each time period that is changed by
agreement, the revised period shall remain in effect until it is
changed. A new request is not necessary for each recurring period.
(2) Where the period specified for compliance is a standard calendar
period, if the initial compliance date occurs after the beginning of the
period, compliance shall be required according to the schedule specified
in paragraphs (m)(i) or (m)(ii) of this section, as appropriate.
(i) Compliance shall be required before the end of the standard
calendar period within which the compliance deadline occurs, if there
remain at least 3 days for tasks that must be performed weekly, at least
2 weeks for tasks that must be performed monthly, at least 1 month for
tasks that must be performed each quarter, or at least 3 months for
tasks that must be performed annually; or
(ii) In all other cases, compliance shall be required before the end
of the first full standard calendar period after the period within which
the initial compliance deadline occurs.
(3) In all instances where a provision of this subpart requires
completion of a task during each multiple successive period, an owner or
operator may perform the required task at any time during the specified
period, provided that the task is conducted at a reasonable interval
after completion of the task during the previous period.

in this section for purposes of this subpart.
Acrylonitrile butadiene styrene latex resin (ABS latex) means ABS
produced through an emulsion process, however the product is not
coagulated or dried as typically occurs in an emulsion process.
Acrylonitrile butadiene styrene resin (ABS) means styrenic
terpolymers consisting primarily of acrylonitrile, 1,3-butadiene, and
styrene monomer units. ABS is usually composed of a styrene-
acrylonitrile copolymer continuous phase with dispersed butadiene
derived rubber.
Acrylonitrile styrene acrylate resin (ASA) means a resin formed
using acrylic ester-based elastomers to impact-modify styrene
acrylonitrile resin matrices.
Aggregate batch vent stream means a gaseous emission stream
containing only the exhausts from two or more batch process vents that
are ducted together before being routed to a control device that is in
continuous operation.
Affected source is defined in Sec. 63.1310(a).
Alpha methyl styrene acrylonitrile resin (AMSAN) means copolymers
consisting primarily of alpha methyl styrene and acrylonitrile.
Average flow rate, as used in conjunction with wastewater
provisions, is determined by the specifications in Sec. 63.144(c); or,
as used in conjunction with batch process vent provisions, is determined
by the specifications in Sec. 63.1323(e).
Batch cycle means the operational step or steps, from start to
finish, that occur as part of a batch unit operation. Batch cycle
limitation means an enforceable restriction on the number of batch
cycles that can be performed in a year for an individual batch process
vent.
Batch emission episode means a discrete emission venting episode
associated with a single batch unit operation. Multiple batch emission
episodes may occur from a single batch unit operation.
Batch process means a discontinuous process involving the bulk
movement of material through sequential manufacturing steps. Mass,
temperature, concentration, and other properties of the process vary
with time. Addition of raw material and withdrawal of product do not
typically occur simultaneously in a batch process. For the purposes of
this subpart, a process producing polymers is characterized as
continuous or batch based on the operation of the polymerization
reactors.
[[Page 185]]
Batch process vent means a point of emission from a batch unit
operation having a gaseous emission stream with annual organic HAP
emissions greater than 225 kilograms per year. Batch process vents
exclude relief valve discharges and leaks from equipment regulated under
Sec. 63.1331.
Batch unit operation means a unit operation operated in a batch
process mode.
Combustion device burner means a device designed to mix and ignite
fuel and air to provide a flame to heat and oxidize waste organic vapors
in a combustion device.
Compounding unit means a unit operation which blends, melts, and
resolidifies solid polymers for the purpose of incorporating additives,
colorants, or stabilizers into the final thermoplastic product. A unit
operation whose primary purpose is to remove residual monomers from
polymers is not a compounding unit.
Continuous process means a process where the inputs and outputs flow
continuously through sequential manufacturing steps throughout the
duration of the process. Continuous processes typically approach steady-
state conditions. Continuous processes typically involve the
simultaneous addition of raw material and withdrawal of product. For the
purposes of this subpart, a process producing polymers is characterized
as continuous or batch based on the operation of the polymerization
reactors.
Continuous process vent means a point of emission from a continuous
unit operation within an affected source having a gaseous emission
stream containing greater than 0.005 weight percent total organic HAP.
Continuous process vents exclude relief valve discharges and leaks from
equipment regulated under Sec. 63.1331.
Continuous unit operation means a unit operation operated in a
continuous process mode.
Control device is defined in Sec. 63.111, except that the term
``process vents'' shall be replaced with the term ``continuous process
vents subject to Sec. 63.1315'' for the purpose of this subpart.
Drawing unit means a unit operation which converts polymer into a
different shape by melting or mixing the polymer and then pulling it
through an orifice to create a continuously extruded product.
Emission point means an individual continuous process vent, batch
process vent, storage vessel, wastewater stream, equipment leak, heat
exchange system, or process contact cooling tower.
Emulsion process means a process carried out with the reactants in
an emulsified form (e.g., polymerization reaction).
Expandable polystyrene resin (EPS) means a polystyrene bead to which
a blowing agent has been added using either an in-situ suspension
process or a post-impregnation suspension process.
Extruding unit means a unit operation which converts polymer into a
different shape by melting or mixing the polymer and then forcing it
through an orifice to create a continuously extruded product.
Group 1 batch process vent means a batch process vent releasing
annual organic HAP emissions greater than the level specified in
Sec. 63.1323(d) and with a cutoff flow rate, calculated in accordance
with Sec. 63.1323(f), greater than or equal to the annual average flow
rate.
Group 2 batch process vent means a batch process vent that does not
fall within the definition of a Group 1 batch process vent.
Group 1 continuous process vent means a continuous process vent
releasing a gaseous emission stream that has a total resource
effectiveness index value, calculated according to Sec. 63.115, less
than or equal to 1.0 unless the continuous process vent is associated
with existing thermoplastic product process units that produce methyl
methacrylate butadiene styrene resin, then said vent falls within the
Group 1 definition if the released emission stream has a total resource
effectiveness index value less than or equal to 3.7.
Group 2 continuous process vent means a continuous process vent that
does not fall within the definition of a Group 1 continuous process
vent.
Group 1 storage vessel means a storage vessel at an existing
affected source that meets the applicability criteria specified in Table
2 or Table 3 of this
[[Page 186]]
subpart, or a storage vessel at a new affected source that meets the
applicability criteria specified in Table 4 or Table 5 of this subpart.
Group 2 storage vessel means a storage vessel that does not fall
within the definition of a Group 1 storage vessel.
Halogenated aggregate batch vent stream means an aggregate batch
vent stream determined to have a total mass emission rate of halogen
atoms contained in organic compounds of 3,750 kilograms per year or
greater determined by the procedures specified in Sec. 63.1323(h).
Halogenated batch process vent means a batch process vent determined
to have a mass emission rate of halogen atoms contained in organic
compounds of 3,750 kilograms per year or greater determined by the
procedures specified in Sec. 63.1323(h).
Halogenated continuous process vent means a continuous process vent
determined to have a mass emission rate of halogen atoms contained in
organic compounds of 0.45 kilograms per hour or greater determined by
the procedures specified in Sec. 63.115(d)(2)(v).
Heat exchange system means any cooling tower system or once-through
cooling water system (e.g., river or pond water) designed and operated
to not allow contact between the cooling medium and process fluid or
gases (i.e., a noncontact system). A heat exchange system can include
more than one heat exchanger and can include recirculating or once-
through cooling systems.
Maintenance wastewater means wastewater generated by the draining of
process fluid from components in the TPPU into an individual drain
system prior to or during maintenance activities. Maintenance wastewater
can be generated during planned and unplanned shutdowns and during
periods not associated with a shutdown. Examples of activities that can
generate maintenance wastewater include descaling of heat exchanger
tubing bundles, cleaning distillation column traps, draining of low legs
and high point bleeds, draining of pumps into an individual drain
system, reactor and equipment washdown, and draining of portions of the
TPPU for repair.
Mass process means a process carried out through the use of thermal
energy (e.g., polymerization reaction). Mass processes do not utilize
emulsifying or suspending agents, but can utilize catalysts or other
additives.
Material recovery section means the equipment that recovers
unreacted or by-product materials from any process section for return to
the TPPU, off-site purification or treatment, or sale. Equipment used to
store recovered materials are not included. Equipment designed to
separate unreacted or by-product material from the polymer product are
to be included in this process section, provided that at the time of
initial compliance some of the material is recovered for reuse in the
process, off-site purification or treatment, or sale. Otherwise, such
equipment are to be assigned to one of the other process sections, as
appropriate. If equipment are used to recover unreacted or by-product
material and return it directly to the same piece of process equipment
from which it was emitted, then said recovery equipment are considered
part of the process section that contains the process equipment. On the
other hand, if equipment are used to recover unreacted or by-product
material and return it to a different piece of process equipment in the
same process section, said recovery equipment are considered part of a
material recovery section. Equipment that treats recovered materials are
to be included in this process section, but equipment that also treats
raw materials are not to be included in this process section. The latter
equipment are to be included in the raw materials preparation section.
Equipment used for the on-site recovery of ethylene glycol from PET
plants, however, are not included in the material recovery section; they
are to be included in the polymerization reaction section. Equipment
used for the on-site recovery of ethylene glycol and other materials
(e.g., methanol) from PET plants are not included in the material
recovery section; these equipment are to be included in the

(1) Using the temperature monitoring device specified by the
applicable monitoring provisions specified for continuous process vents
in Sec. 63.1315, an average exit temperature shall be determined based
on the average exit temperature for three performance tests. The average
exit temperature for each 3-hour performance test shall be based on
measurements taken at least every 15 minutes for 3 hours of continuous
operation under maximum representative operating conditions for the
process. For emissions streams containing continuous and batch process
vents, the maximum representative operating conditions shall be during
periods when batch emission episodes are venting to the control device
resulting in the highest concentration of organic HAP in the emissions
stream.
(2) As specified in Sec. 63.1317(b), continuous compliance shall be
determined based on an average exit temperature determined for each
consecutive 3-hour continuous period. Each 3-hour period where the
average exit temperature is more than 6 deg.C (10 deg.F) above the
applicable specified temperature limit shall be considered an exceedance
of the monitoring provisions.

continuous process vents by 84 weight percent. Compliance with this
paragraph (a)(3) shall be demonstrated using the procedures specified in
Sec. 63.1333(c).
(b) Aggregate batch vent streams. The owner or operator of an
aggregate batch vent stream that contains one or more Group 1 batch
process vents shall comply with the requirements of either paragraph
(b)(1) or (b)(2) of this section, except as provided for in paragraph

[[Page 201]]
can be based on either organic HAP or TOC.
(1) For each aggregate batch vent stream, reduce organic HAP
emissions using a flare.
(i) The flare shall comply with the requirements of Sec. 63.11(b).
(ii) Halogenated aggregate batch vent streams, as defined in

emissions by 90 weight percent or to a concentration of 20 parts per
million by volume, whichever is less stringent, on a continuous basis
using a control device. For purposes of complying with the 20 parts per
million by volume outlet concentration standard, the outlet
concentration shall be calculated on a dry basis. When a combustion
device is used for purposes of complying with the 20 parts per million
by volume outlet concentration standard, the concentration shall be
corrected to 3 percent oxygen if supplemental combustion air is used to
combust the emissions. If supplemental combustion air is not used, a
correction to 3 percent oxygen is not required.
(3) The owner or operator of a new affected source producing SAN
using a batch process shall comply with paragraph (a)(3) of this
section.
(c) Halogenated emissions. Halogenated Group 1 batch process vents,
halogenated aggregate batch vent streams, and halogenated continuous

(a)(2), (a)(3), (b)(2), or (b)(3) of this section, as appropriate, shall
be controlled according to either paragraph (c)(1) or (c)(2) of this
section.
(1) If a combustion device is used to comply with paragraph (a)(2),
(a)(3), (b)(2), or (b)(3) of this section for a halogenated batch
process vent, halogenated aggregate batch vent stream, or halogenated
continuous process vent, said emissions shall be ducted from the
combustion device to an additional control device that reduces overall
emissions of hydrogen halides and halogens by 99 percent before said
emissions are discharged to the atmosphere.
(2) A control device may be used to reduce the halogen atom mass
emission rate of said emissions to less than 3,750 kg/yr for batch
process vents or aggregate batch vent streams and to less than 0.45
kilograms per hour for continuous process vents prior to venting to any
combustion control device, and thus make the batch process vent,
aggregate batch vent stream, or continuous process vent nonhalogenated.
The nonhalogenated batch process vent, aggregate batch vent stream, or
continuous process vent must then comply with the requirements of either
paragraph (a) or (b) of this section, as appropriate.
(d) If a boiler or process heater is used to comply with the percent
reduction requirement specified in paragraph (a)(2), (a)(3), (b)(2), or

stream, or continuous process vent shall be introduced into the flame
zone of such a device.
(e) Combination of batch process vents or aggregate batch vent
streams with continuous process vents. A batch process vent or aggregate
batch vent stream combined with a continuous process vent is not subject
to the provisions of Secs. 63.1323 through 63.1327, providing the
requirements of paragraphs (e)(1), (e)(2), and either (e)(3) or (e)(4)
of this section are met.

combined with a continuous process vent prior to being routed to a
control device, the combined vent stream shall comply with the
requirements in Sec. 63.1315(a)(10). In this paragraph (e)(3), the
definition of control device as it relates to continuous process vents
shall be used.
[[Page 202]]
(4) If the batch process vent or aggregate batch vent stream is
combined with a continuous process vent prior to being routed to a
recovery device, the combined vent stream shall comply with the
requirements in Sec. 63.1315(a)(11). In this paragraph (e)(4), the
definition of recovery device as it relates to continuous process vents
shall be used.
(f) Group 2 batch process vents with annual emissions greater than
or equal to the level specified in Sec. 63.1323(d). The owner or

Sec. 63.1323 Batch process vents--methods and procedures for group determination.
(a) General requirements. Except as provided in paragraph (a)(3) of
this section and in Sec. 63.1321(b)(1), the owner or operator of batch
process vents at affected sources shall determine the group status of
each batch process vent in accordance with the provisions of this
section. This determination may be based on either organic HAP or TOC
emissions.
(1) The procedures specified in paragraphs (b) through (h) of this
section shall be followed for the expected mix of products for a given
batch process vent, as specified in paragraph (a)(1)(i) of this section,
or for the worst-case HAP emitting product, as specified in paragraphs
(a)(1)(ii) through (a)(1)(iv) of this section. ``Worst-case HAP emitting
product'' is defined in paragraph (a)(1)(iii) of this section.
(i) If an owner or operator chooses to follow the procedures
specified in paragraphs (b) through (h) of this section for the expected
mix of products, an identification of the different products and the
number of batch cycles accomplished for each is required as part of the
group determination documentation, as specified in Sec. 63.1326(a)(1).
(ii) If an owner or operator chooses to follow the procedures
specified in paragraphs (b) through (h) of this section for the worst-
case HAP emitting product, documentation identifying the worst-case HAP
emitting product is required as part of the group determination
documentation, as specified in Sec. 63.1326(a)(1).
(iii) Except as specified in paragraph (a)(1)(iii)(B) of this
section, the worst-case HAP emitting product is as defined in paragraph
(a)(1)(iii)(A) of this section.
(A) The worst-case HAP emitting product is the one with the highest
mass emission rate (kg organic HAP per hour) averaged over the entire
time period of the batch cycle.
(B) Alternatively, when one product is produced more than 75 percent
of the time, accounts for more than 75 percent of the annual mass of
product, and the owner or operator can show that the mass emission rate
(kg organic HAP per hour) averaged over the entire time period of the
batch cycle can reasonably be expected to be similar to the mass
emission rate for other products having emissions from the same batch
process vent, said product may be considered the worst-case HAP emitting
product.
(C) An owner or operator shall determine the worst-case HAP emitting
product for a batch process vent as specified in paragraphs
(a)(1)(iii)(C)(1) through (a)(1)(iii)(C)(3) of this section.
[[Page 203]]
(1) The emissions per batch emission episode shall be determined
using any of the procedures specified in paragraph (b) of this section.
The mass emission rate (kg organic HAP per hour) averaged over the
entire time period of the batch cycle shall be determined by summing the
emissions for each batch emission episode making up a complete batch
cycle and dividing by the total duration in hours of the batch cycle.
(2) To determine the worst-case HAP emitting product as specified
under paragraph (a)(1)(iii)(A) of this section, the mass emission rate
for each product shall be determined and compared.
(3) To determine the worst-case HAP emitting product as specified
under paragraph (a)(1)(iii)(B) of this section, the mass emission rate
for the product meeting the time and mass criteria of paragraph
(a)(1)(iii)(B) of this section shall be determined, and the owner or
operator shall provide adequate information to demonstrate that the mass
emission rate for said product is similar to the mass emission rates for
the other products having emissions from the same batch process vent. In
addition, the owner or operator shall provide information demonstrating
that the selected product meets the time and mass criteria of paragraph
(a)(1)(iii)(B) of this section.
(iv) The annual production of the worst-case HAP emitting product
shall be determined by ratioing the production time of said product up
to a 12 month period of actual production. It is not necessary to ratio
up to a maximum production rate (i.e., 8,760 hours per year at maximum
design production).
(2) The annual uncontrolled organic HAP or TOC emissions and annual
average batch vent flow rate shall be determined at the exit from the
batch unit operation. For the purposes of these determinations, the
primary condenser operating as a reflux condenser on a reactor or
distillation column, the primary condenser recovering monomer, reaction
products, by-products, or solvent from a stripper operated in batch
mode, and the primary condenser recovering monomer, reaction products,
by-products, or solvent from a distillation operation operated in batch
mode shall be considered part of the batch unit operation. All other
devices that recover or oxidize organic HAP or TOC vapors shall be
considered control devices as defined in Sec. 63.1312.
(3) The owner or operator of a batch process vent complying with the
flare provisions in Sec. 63.1322(a)(1) or Sec. 63.1322(b)(1) or routing
the batch process vent to a control device to comply with the
requirements in Sec. 63.1322(a)(2) or Sec. 63.1322(b)(2) is not required
to perform the batch process vent group determination described in this
section, but shall comply with all requirements applicable to Group 1
batch process vents for said batch process vent.
(b) Determination of annual emissions. The owner or operator shall
calculate annual uncontrolled TOC or organic HAP emissions for each
batch process vent using the methods described in paragraphs (b)(1)
through (b)(8) of this section. Paragraphs (b)(1) through (b)(4) of this
section present procedures that can be used to calculate the emissions
from individual batch emission episodes. Emissions from batch processes
involving multicomponent systems are to be calculated using the
procedures in paragraphs (b)(1) through (b)(4) of this section.
Individual HAP partial pressures in multicomponent systems shall be
determined by the following methods: If the components are miscible in
one another, use Raoult's law to calculate the partial pressures; if the
solution is a dilute aqueous mixture use Henry's law constants to
calculate partial pressures; if Raoult's law or Henry's law are not
appropriate (or available) use experimentally obtained activity
coefficients, Henry's law constants, or solubility data; if Raoult's law
or Henry's law are not appropriate use models, such as the group-
contribution models, to predict activity coefficients; and if Raoult's
law or Henry's law are not appropriate assume the components of the
system behave independently and use the summation of all vapor pressures
from the HAP's as the total HAP partial pressure. Chemical property data
can be obtained from standard reference texts. Paragraph
[[Page 204]]
(b)(5) of this section describes how direct measurement can be used to
estimate emissions. If the owner or operator can demonstrate that the
procedures in paragraphs (b)(1) through (b)(4) of this section are not
appropriate to estimate emissions from a batch emission episode,
emissions may be estimated using engineering assessment, as described in
paragraph (b)(6) of this section. Owners or operators are not required
to demonstrate that direct measurement is not appropriate before
utilizing engineering assessment. Paragraph (b)(6)(ii) of this section
describes how an owner or operator shall demonstrate that the procedures
in paragraphs (b)(1) through (b)(4) of this section are not appropriate.
Emissions from a batch cycle shall be calculated in accordance with
paragraph (b)(7) of this section, and annual emissions from the batch
process vent shall be calculated in accordance with paragraph (b)(8) of

The owner or operator choosing either of these options must develop an
emission profile for the entire batch emission episode, based on either
process knowledge or test data collected, to demonstrate that test
periods are representative. Examples of information that could
constitute process knowledge include calculations based on material
balances and process stoichiometry. Previous test results may be used

temporary process changes.
(2) The owner or operator shall redetermine the percent emission
reduction achieved using the procedures specified in Sec. 63.1333(c). If
engineering assessment, as described in paragraph (b)(6)(i) of this
section, can demonstrate that the process change did not cause the
percent emission reduction to decrease, it may be used in lieu of
redetermining the percent reduction using the procedures specified in
Sec. 63.1333(c).
(3) Where the redetermined percent reduction is less than 84
percent, the owner or operator shall submit a report as specified in
Sec. 63.1327(d) and shall comply with Sec. 63.1322(a)(3) and all
associated provisions in accordance with the compliance schedule
described in Sec. 63.1335(e)(6)(iii)(D)(2).

compliance with Sec. 63.1322(c) [halogenated emission streams]. An owner
or operator controlling halogenated emissions in compliance with
Sec. 63.1322(c) shall conduct a performance test to determine compliance
with the control efficiency specified in Sec. 63.1322(c)(1) or the
emission limit specified in Sec. 63.1322(c)(2) for hydrogen halides and
halogens.
(1) Sampling sites shall be located at the inlet and outlet of the

subtracting the outlet mass emissions from the inlet mass emissions and
then dividing the result by the inlet mass emissions.
(4) To determine compliance with the emission limit specified in
Sec. 63.1322(c)(2), the annual mass emissions for any hydrogen halides
and halogens present at the outlet of the control device and prior to
any combustion device shall be summed together and compared to the
emission limit specified in Sec. 63.1322(c)(2).
(5) The owner or operator may use any other method to demonstrate
compliance if the method or data has been validated according to the
applicable procedures of Method 301 of appendix A of this part.
(e) Aggregate batch vent stream testing for compliance with
Sec. 63.1322(b)(2) or (b)(3). Except as specified in paragraphs (e)(1)

the standard deviation of the response from the zero calibration gas
when the instrument is zeroed on the most sensitive scale.
(3) When a combustion device is used to comply with the 20 parts per
million by volume outlet concentration standard specified in
Sec. 63.1322(b)(2), the correction to 3 percent oxygen specified in the
performance testing procedures of Sec. 63.116(c)(3) and
Sec. 63.116(c)(3)(iii) is only required when supplemental combustion air
is used to combust the emissions, for the purposes of this subpart.
(f) Compliance with Sec. 63.1322(a)(3) [new SAN batch affected
sources]. Except as provided in paragraph (b) of this section, an owner

in Sec. 63.1333(c) and the control device efficiencies specified in
either paragraph (f)(4)(i) or (f)(4)(ii) of this section. Emissions for
uncontrolled continuous process vents and aggregate batch vent streams
shall be determined based on the direct measurement procedures specified
in paragraph (f)(2) and (f)(3) of this section, respectively, or based
on engineering assessment, as specified in Sec. 63.1323(b)(6)(i). At the
discretion of the owner or operator, emissions for uncontrolled batch
process vents shall be determined based on any of the procedures in
Sec. 63.1323(b).
(i) For noncombustion devices, the control efficiency shall be as
determined by the performance test required by paragraph (f)(1), (f)(2),

required by paragraph (c) of this section, the control efficiency shall
be determined by the owner or operator based on engineering assessment.
(ii) For combustion devices, the control efficiency shall be as
determined by the performance test required by paragraph (f)(1), (f)(2),
or (f)(3) of this section. Alternatively, if a performance test is not
required, the control efficiency shall be 98 percent. The control
efficiency for a flare shall be 98 percent.
(g) Batch cycle limitation. The batch cycle limitation required by
Sec. 63.1322 (f) and (g) shall be established as specified in paragraph
(g)(1) of this section and shall include the elements specified in
paragraph (g)(2) of this section.
(1) The batch cycle limitation shall be determined by the owner or
operator such that annual emissions for the batch process vent remain
less than the level specified in Sec. 63.1323(d) when complying with
Sec. 63.1322(g). Alternatively, when complying with Sec. 63.1322(f), the
batch cycle limitation shall ensure that annual emissions remain at a
level such that said batch process vent remains a Group 2 batch process
vent, given the actual annual flow rate for said batch process vent
determined according to the procedures specified in Sec. 63.1323(e). The
batch cycle limitation shall be determined using the same basis, as
described in Sec. 63.1323(a)(1), used to make the group determination
(i.e., expected mix of products or worst-case HAP emitting product). The
establishment of the batch cycle limitation is not dependent upon any
past production or activity level.
(i) If the expected mix of products serves as the basis for the
batch cycle limitation, the batch cycle limitation shall be determined
such that any foreseeable combination of products which the owner or
operator desires the flexibility to manufacture shall be allowed.
Combinations of products not accounted for in the documentation required
by paragraph (g)(2)(iv) of this section shall not be allowed within the
restrictions of the batch cycle limitation.
(ii) If, for a batch process vent with more than one product, a
single worst-case HAP emitting product serves as the basis for the batch
cycle limitation, the batch cycle limitation shall be determined such
that the maximum number of batch cycles the owner or operator desires
the flexibility to accomplish, using the worst-case HAP emitting product
and ensuring that the batch process vent remains a Group 2 batch process
vent or that emissions remain less than the level specified in
[[Page 221]]
Sec. 63.1323(d), shall be allowed. This value shall be the total number
of batch cycles allowed within the restrictions of the batch cycle
limitation regardless of which products are manufactured.
(2) Documentation supporting the establishment of the batch cycle
limitation shall include the information specified in paragraphs
(g)(2)(i) through (g)(2)(v) of this section, as appropriate.
(i) Identification that the purpose of the batch cycle limitation is
to comply with Sec. 63.1322 (f)(1) or (g)(1).
(ii) Identification that the batch cycle limitation is based on a
single worst-case HAP emitting product or on the expected mix of
products for said batch process vent as allowed under
Sec. 63.1323(a)(1).
(iii) Definition of operating year for purposes of determining
compliance with the batch cycle limitation.
(iv) If the batch cycle limitation is based on a single worst-case
HAP emitting product, documentation specified in Sec. 63.1323 (a)(1)(ii)
through (a)(1)(iv), as appropriate, describing how the single product
meets the requirements for worst-case HAP emitting product and the
number of batch cycles allowed under the batch cycle limitation.
(v) If the batch cycle limitation is based on the expected mix of
products, the owner or operator shall provide documentation that
describes as many scenarios for differing mixes of products (i.e., how
many batch cycles for each product) that the owner or operator desires
the flexibility to accomplish. Alternatively, the owner or operator
shall provide a description of the relationship among the mix of
products that will allow a determination of compliance with the batch
cycle limitation under an infinite number of scenarios. For example, if
a batch process vent has two products, each product has the same flow
rate and emits for the same amount of time, and product No. 1 has twice
the emissions as product No. 2, the relationship describing an infinite
number of scenarios would be that the owner or operator can accomplish
two batch cycles of product No. 2 for each batch cycle of product No. 1
within the restriction of the batch cycle limitation.

semi-annual Periodic Report required under Sec. 63.1335(e)(6), for the
purposes of this subpart. If the leak remains unrepaired, the
information shall also be submitted in each subsequent Periodic Report,
until the repair of the leak is reported.
(d) The compliance date for heat exchange systems subject to the
provisions of this section is specified in Sec. 63.1311.
Sec. 63.1329 Process contact cooling towers provisions.
(a) This section applies to each new affected source that
manufactures PET and each existing affected source that manufactures PET
using a continuous terephthalic acid high viscosity multiple end
finisher process. The owner or operator a new affected source shall
comply with paragraph (b) of this section. The owner or operator of an
existing affected source that manufactures PET using a continuous
terephthalic acid high viscosity multiple end finisher process shall
comply with paragraph (c) of this section. The compliance data for
process contact cooling towers subject to the provisions of this section
is specified in Sec. 63.1311.
(b) New affected source requirements. The owner or operator of a new
affected source subject to this section shall comply with paragraphs
(b)(1) through (b)(2) of this section.
(1) The owner or operator of a new affected source subject to this
section shall not send contact condenser effluent associated with a
vacuum system to a process contact cooling tower.
(2) The owner or operator of a new affected source subject to this
section shall indicate in the Notification of Compliance Status, as
required in
[[Page 226]]
Sec. 63.1335(e)(5), that contact condenser effluent associated with
vacuum systems is not sent to process contact cooling towers.
(c) Existing affected source requirements. The owner or operator of
an existing affected source subject to this section who manufactures PET
using a continuous terephthalic acid high viscosity multiple end
finisher process, and who is subject or becomes subject to 40 CFR part
60, subpart DDD, shall maintain an ethylene glycol concentration in the
cooling tower at or below 4.0 percent by weight averaged on a daily
basis over a rolling 14-day period of operating days. Compliance with
this paragraph (c) shall be determined as specified in paragraphs (c)(1)
through (c)(4) of this section.
(1) To determine the ethylene glycol concentration, owners or
operators shall follow the procedures specified in 40 CFR 60.564(j)(1),
except as provided in paragraph (c)(2) of this section.
(i) At least one sample per operating day shall be collected using
the procedures specified in 40 CFR 60.564(j)(1)(i). An average ethylene
glycol concentration by weight shall be calculated on a daily basis over
a rolling 14-day period of operating days. Each daily average ethylene
glycol concentration so calculated constitutes a performance test.
Exceedance of the standard during the reduced testing program specified
in paragraph (b)(1)(ii) of this section is a violation of these
standards.
(ii) The owner or operator may elect to reduce the sampling program
to any 14 consecutive day period once every two calendar months, if at
least seventeen consecutive 14-day rolling average concentrations
immediately preceding the reduced sampling program are each less than
1.2 weight percent ethylene glycol. If the average concentration
obtained over the 14 day sampling during the reduced test period exceeds
the upper 95 percent confidence interval calculated from the most recent
test results in which no one 14-day average exceeded 1.2 weight percent
ethylene glycol, then the owner or operator shall reinstitute a daily
sampling program. The 95 percent confidence interval shall be calculated
as specified in paragraph (b)(1)(iii) of this section. A reduced program
may be reinstituted if the requirements specified in this paragraph
(c)(1)(ii) are met.
(iii) The upper 95 percent confidence interval shall be calculated
using the Equation 27 of this subpart:
[GRAPHIC] [TIFF OMITTED] TR12SE96.026
where:
Xi = daily ethylene glycol concentration for each day used to
calculate each 14-day rolling average used in test results to justify
implementing the reduced testing program.
n = number of ethylene glycol concentrations.
(2) Measuring an alternative parameter, such as carbon oxygen demand
or biological oxygen demand, that is demonstrated to be directly
proportional to the ethylene glycol concentration shall be allowed. Such
parameter shall be measured during the initial 14-day performance test
during which the facility is shown to be in compliance with the ethylene
glycol concentration standard whereby the ethylene glycol concentration
is determined using the procedures described in paragraph (b)(1) of this
section. The alternative parameter shall be measured on a daily basis
and the average value of the alternative parameter shall be calculated
on a daily basis over a rolling 14-day period of operating days. Each
daily average value of the alternative parameter constitutes a
performance test.
(3) During each performance test, daily measurement and daily
average 14-day rolling averages of the ethylene
[[Page 227]]
glycol concentration in the cooling tower water shall be recorded. For
the initial performance test, these records shall be submitted in the
Notification of Compliance Status report.
(4) All periods when the 14-day rolling average exceeds the standard
shall be reported in the Periodic Report.

affected source subject to this subpart need not comply for the purposes
of this subpart.
(8) When the term ``range'' is used in Sec. 63.143(f), the term
``level'' shall be used instead for the purposes of this subpart. This
level shall be determined using the procedures specified in
Sec. 63.1334.
(9) For the purposes of this subpart, owners or operators are not
required to comply with the provisions of Sec. 63.138(e)(2) which
specify that owners or operators shall demonstrate that 95 percent of
the mass of HAP, as listed in Table 9 of subpart G of this part, is
removed from the wastewater stream or combination of wastewater streams
by the procedure specified in Sec. 63.145(i) for a biological treatment

calibration gas when the instrument is zeroed on the most sensitive
scale.
(12) The compliance date for the affected source subject to the
provisions of this section is specified in Sec. 63.1311.
(b) For each affected source, the owner or operator shall comply
with the requirements for maintenance wastewater in Sec. 63.105, except
that when
[[Page 228]]

the owner or operator of each affected source shall comply with the
requirements of subpart H of this part, with the differences noted in
paragraphs (a)(1) through (a)(10) of this section.
(1) For an affected source producing polystyrene resin, the
indications of liquids dripping, as defined in subpart H of this part,
from bleed ports in pumps and agitator seals in light liquid service
shall not be considered to be a leak. For purposes of this subpart, a
``bleed port'' is a technologically-required feature of the pump or seal
whereby polymer fluid used to provide lubrication and/or cooling of the
pump or agitator shaft exits the pump, thereby resulting in a visible
dripping of fluid.
(2) The compliance date for the equipment leak provisions contained
in this section is provided in Sec. 63.1311.
(3) Owners and operators of an affected source subject to this
subpart are not required to submit the Initial Notification required by
Sec. 63.182(a)(1) and Sec. 63.182(b).
(4) The Notification of Compliance Status required by paragraphs
Sec. 63.182(a)(2) and Sec. 63.182(c) shall be submitted within 150 days
(rather than 90 days) of the applicable compliance date specified in
Sec. 63.1311 for the equipment leak provisions. Said notification can be
submitted as part of the Notification of Compliance Status required by
Sec. 63.1335(e)(5).
(5) The Periodic Reports required by Sec. 63.182(a)(3) and
Sec. 63.182(d) may be submitted as part of the Periodic Reports required
by Sec. 63.1335(e)(6).
(6) For an affected source producing PET, an owner or operator shall
comply with the requirements of paragraphs (a)(6)(i) and (a)(6)(ii) of
this section instead of with the requirements of Sec. 63.169 for pumps,
valves, connectors, and agitators in heavy liquid service; pressure
relief devices in light liquid or heavy liquid service; and
instrumentation systems.
(i) A leak is determined to be detected if there is evidence of a
potential leak found by visual, audible, olfactory, or any other
detection method except that Method 21, 40 CFR part 60, appendix A shall
not be used to determine if a leak is detected.
(ii)(A) When a leak is detected, it shall be repaired as soon as
practicable, but not later than 15 calendar days after it is detected,
except as provided in Sec. 63.171.
(B) The first attempt at repair shall be made no later than 5
calendar days after each leak is detected.
(C) Repaired shall mean that the visual, audible, olfactory, or
other indications of a leak have been eliminated; that no bubbles are
observed at potential leak sites during a leak check using soap
solution; or that the system will hold a test pressure.
(7) For each affected source producing PET, an owner or operator is
not required to develop an initial list of identification numbers for
the equipment identified in paragraph (a)(6) of this section (i.e.,
pumps, valves, connectors, and agitators in heavy liquid service;
pressure relief devices in light liquid or heavy liquid service; and
instrumentation systems) as would otherwise be required under
Sec. 63.181(b)(1)(i).
(8) When the provisions of subpart H of this part specify that
Method 18, 40 CFR part 60, appendix A, shall be used, Method 18 or
Method 25A, 40 CFR part 60, appendix A, may be used for the purposes of
this subpart. The use of Method 25A, 40 CFR part 60, appendix A, shall
comply with paragraphs (a)(8)(i) and (a)(8)(ii) of this section.
(i) The organic HAP used as the calibration gas for Method 25A, 40
CFR part 60, appendix A, shall be the single organic HAP representing
the largest percent by volume of the emissions.
[[Page 229]]
(ii) The use of Method 25A, 40 CFR part 60, appendix A, is
acceptable if the response from the high-level calibration gas is at
least 20 times the standard deviation of the response from the zero
calibration gas when the instrument is zeroed on the most sensitive
scale.
(9) For purposes of this subpart, bottoms receivers and surge
control vessels are not considered equipment for purposes of this
section and are not subject to the requirements of subpart H of this
part.
(10) The owner or operator of each affected source shall substitute
the phrase ``the provisions of subparts F, I, or JJJ of this part'' for
both the phrases ``the provisions of subparts F or I of this part'' and
the phrase ``the provisions of subpart F or I of this part'' throughout
Secs. 63.163 and 63.168, for the purposes of this subpart. In addition,
the owner or operator of each affected source shall substitute the
phrase ``subparts F, I, and JJJ'' for the phrase ``subparts F and I'' in
Sec. 63.174(c)(2)(iii), for the purposes of this subpart.
(b) The provisions of this section do not apply to each TPPU
producing PET using a process other than a continuous terephthalic acid
(TPA) high viscosity multiple end finisher process that is part of an
affected source if all of the components in the TPPU are either in
vacuum service or in heavy liquid service.
(1) Owners and operators of a TPPU exempted under paragraph (b) of
this section shall retain at the facility information, data, and
analyses used to demonstrate that all of the components in the exempted
TPPU are either in vacuum service or in heavy liquid service. Such
documentation shall include an analysis or demonstration that the
process fluids do not meet the criteria of ``in light liquid service''
or ``in gas or vapor service.'' Examples of information that could
document this include, but are not limited to, records of chemicals
purchased for the process, analyses of process stream composition,
engineering calculations, or process knowledge.
(2) If changes occur at a TPPU exempted under paragraph (b) of this
section such that all of the components in the TPPU are no longer either
in vacuum service or in heavy liquid service (e.g., by either process
changes or the addition of new components), the owner or operator shall
comply with the provisions of this section for all of the components at
the TPPU. The owner or operator shall submit a report within 180 days
after the process change is made or the information regarding the
process change is known to the owner or operator. This report may be
included in the next Periodic Report, as specified in paragraph (a)(5)
of this section. The following information shall be submitted:
(i) A description of the process change; and
(ii) A schedule for compliance with the provisions of
Sec. 63.1331(a), as specified in paragraphs (b)(2)(ii)(A) and
(b)(2)(ii)(B) of this section.
(A) The owner or operator shall submit to the Administrator for
approval a compliance schedule and a justification for the schedule.
(B) The Administrator shall approve the compliance schedule or
request changes within 120 operating days of receipt of the compliance
schedule and justification.

source producing PET using a continuous TPA high viscosity multiple end
finisher process.
[61 FR 48229, Sept. 12, 1996, as amended at 62 FR 37722, July 15, 1997]
Sec. 63.1332 Emissions averaging provisions.
(a) This section applies to owners or operators of existing affected
sources who seek to comply with Sec. 63.1313(b) by using emissions
averaging rather than following the provisions of Secs. 63.1314,
63.1315, 63.1316 through 63.1320, 63.1321, and 63.1330.
(1) The following emission point limitations apply to the use of
these provisions:
(i) All emission points included in an emissions average shall be
from the same affected source. There may be an emissions average for
each affected source located at a plant site.
(ii)(A) If a plant site has only one affected source for which
emissions averaging is being used to demonstrate
[[Page 230]]
compliance, the number of emission points allowed in the emissions
average for said affected source is limited to twenty. This number may
be increased by up to five additional emission points if pollution
prevention measures are used to control five or more of the emission
points included in the emissions average.
(B) If a plant site has two or more affected sources for which
emissions averaging is being used to demonstrate compliance, the number
of emission points allowed in the emissions averages for said affected
sources is limited to twenty. This number may be increased by up to five
additional emission points if pollution prevention measures are used to
control five or more of the emission points included in the emissions
averages.
(2) Compliance with the provisions of this section may be based on
either organic HAP or TOC.
(3) For the purposes of these provisions, whenever Method 18, 40 CFR
part 60, appendix A, is specified within the paragraphs of this section
or is specified by reference through provisions outside this section,
Method 18 or Method 25A, 40 CFR part 60, appendix A, may be used. The
use of Method 25A, 40 CFR part 60, appendix A, shall conform with the
requirements in paragraphs (a)(3)(i) and (a)(3)(ii) of this section.
(i) The organic HAP used as the calibration gas for Method 25A, 40
CFR part 60, appendix A shall be the single organic HAP representing the
largest percent by volume of the emissions.
(ii) The use of Method 25A, 40 CFR part 60, appendix A is acceptable
if the response from the high-level calibration gas is at least 20 times
the standard deviation of the response from the zero calibration gas
when the instrument is zeroed on the most sensitive scale.
(b) Unless an operating permit application has been submitted, the
owner or operator shall develop and submit for approval an Emissions
Averaging Plan containing all of the information required in
Sec. 63.1335(e)(4) for all emission points to be included in an
emissions average.
(c) Paragraphs (c)(1) through (c)(5) of this section describe the
emission points that may be used to generate emissions averaging credits
if control was applied after November 15, 1990, and if sufficient
information is available to determine the appropriate value of credits
for the emission point. Paragraph (c)(6) of this section discusses the
use of pollution prevention in generating emissions averaging credits.
(1) Storage vessels, batch process vents, aggregate batch vent
streams, continuous process vents subject to Sec. 63.1315, and process
wastewater streams that are determined to be Group 2 emission points.
The term ``continuous process vents subject to Sec. 63.1315'' includes
continuous process vents subject to Sec. 63.1316 (b)(1)(iii),
(b)(2)(iii), and (c)(2), which reference Sec. 63.1315.
(2) Continuous process vents located in the collection of material
recovery sections within the affected source at an existing affected
source producing PET using a continuous dimethyl terephthalate process
subject to Sec. 63.1316(b)(1)(i) where the uncontrolled organic HAP
emissions from said continuous process vents are equal to or less than
0.12 kg organic HAP per Mg of product. These continuous process vents
shall be considered Group 2 emission points for the purposes of this
section.
(3) Storage vessels, continuous process vents subject to
Sec. 63.1315, and process wastewater streams that are determined to be
Group 1 emission points and that are controlled by a technology that the
Administrator or permitting authority agrees has a higher nominal
efficiency than the reference control technology. Information on the
nominal efficiencies for such technologies shall be submitted and
approved as provided in paragraph (i) of this section.
(4) Batch process vents and aggregate batch vent streams that are
determined to be Group 1 emission points and that are controlled to a
level more stringent than the applicable standard.
(5) Continuous process vents subject to Sec. 63.1316 (b)(1)(i),
(b)(1)(ii), (b)(2)(i), (b)(2)(ii), or (c)(1) located in the collection
of process sections within the affected source, as specified in
paragraphs (c)(5)(i) through (c)(5)(ii) of this
[[Page 231]]
section. The continuous process vents identified in paragraphs (c)(5)(i)
through (c)(5)(ii) of this section shall be considered to be Group 1
emission points for the purposes of this section.
(i) Continuous process vents subject to Sec. 63.1316(b)(1)(i)
located in the collection of material recovery sections within the
affected source where the uncontrolled organic HAP emissions for said
continuous process vents are greater than 0.12 kg organic HAP per Mg of
product and said continuous process vents are controlled to a level more
stringent than the applicable standard.
(ii) Continuous process vents subject to Sec. 63.1316(b)(1)(ii),
(b)(2)(i), (b)(2)(ii), or (c)(1) located in the collection of process
sections within the affected source where the uncontrolled organic HAP
emissions from said continuous process vents are controlled to a level
more stringent than the applicable standard.
(6) The percent reduction for any storage vessel, batch process
vent, aggregate batch vent stream, continuous process vent, and process
wastewater stream from which emissions are reduced by pollution
prevention measures shall be determined using the procedures specified
in paragraph (j) of this section.
(i) For a Group 1 storage vessel, batch process vent, aggregate
batch vent stream, continuous process vent, or process wastewater
stream, the pollution prevention measure must reduce emissions more than
if the applicable reference control technology or standard had been
applied to the emission point instead of the pollution prevention
measure, except as provided in paragraph (c)(6)(ii) of this section.
(ii) If a pollution prevention measure is used in conjunction with
other controls for a Group 1 storage vessel, batch process vent,
aggregate batch vent stream, continuous process vent, or process
wastewater stream, the pollution prevention measure alone does not have
to reduce emissions more than the applicable reference control
technology or standard, but the combination of the pollution prevention
measure and other controls must reduce emissions more than if the
applicable reference control technology or standard had been applied
instead of the pollution prevention measure.
(d) The following emission points cannot be used to generate
emissions averaging credits:
(1) Emission points already controlled on or before November 15,
1990, cannot be used to generate credits unless the level of control is
increased after November 15, 1990. In this case, credit will be allowed
only for the increase in control after November 15, 1990.
(2) Group 1 emission points, identified in paragraph (c)(3) of this
section, that are controlled by a reference control technology cannot be
used to generate credits unless the reference control technology has
been approved for use in a different manner and a higher nominal
efficiency has been assigned according to the procedures in paragraph
(i) of this section.
(3) Emission points for nonoperating TPPU cannot be used to generate
credits. TPPU that are shutdown cannot be used to generate credits or
debits.
(4) Maintenance wastewater cannot be used to generate credits.
Wastewater streams treated in biological treatment units cannot be used
to generate credits. These two types of wastewater cannot be used to
generate credits or debits. For the purposes of this section, the terms
wastewater and wastewater stream are used to mean process wastewater.
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart cannot be used to generate credits, unless
the level of control has been increased after November 15, 1990, to a
level above what is required by the other State or Federal rule. Only
the control above what is required by the other State or Federal rule
will be credited. However, if an emission point has been used to
generate emissions averaging credit in an approved emissions average,
and the emission point is subsequently made subject to a State or
Federal rule other than this subpart, the emission point may continue to
generate emissions averaging credit for the purpose of complying with
the previously approved emissions average.
(e) For all emission points included in an emissions average, the
owner or
[[Page 232]]
operator shall perform the following tasks:
(1) Calculate and record monthly debits for all Group 1 emission
points that are controlled to a level less stringent than the reference
control technology or standard for those emission points. Said Group 1
emission points are identified in paragraphs (c)(3) through (c)(5) of
this section. Equations in paragraph (g) of this section shall be used
to calculate debits.
(2) Calculate and record monthly credits for all Group 1 and Group 2
emission points that are over-controlled to compensate for the debits.
Equations in paragraph (h) of this section shall be used to calculate
credits. Emission points and controls that meet the criteria of
paragraph (c) of this section may be included in the credit calculation,
whereas those described in paragraph (d) of this section shall not be
included.
(3) Demonstrate that annual credits calculated according to
paragraph (h) of this section are greater than or equal to debits
calculated for the same annual compliance period according to paragraph
(g) of this section.
(i) The owner or operator may choose to include more than the
required number of credit-generating emission points in an emissions
average in order to increase the likelihood of being in compliance.
(ii) The initial demonstration in the Emissions Averaging Plan or
operating permit application that credit-generating emission points will
be capable of generating sufficient credits to offset the debits from
the debit-generating emission points shall be made under representative
operating conditions. After the compliance date, actual operating data
will be used for all debit and credit calculations.
(4) Demonstrate that debits calculated for a quarterly (3-month)
period according to paragraph (g) of this section are not more than 1.30
times the credits for the same period calculated according to paragraph
(h) of this section. Compliance for the quarter shall be determined
based on the ratio of credits and debits from that quarter, with 30
percent more debits than credits allowed on a quarterly basis.
(5) Record and report quarterly and annual credits and debits in the
Periodic Reports as specified in Sec. 63.1335(e)(6). Every fourth
Periodic Report shall include a certification of compliance with the
emissions averaging provisions as required by
Sec. 63.1335(e)(6)(x)(C)(2).
(f) Debits and credits shall be calculated in accordance with the
methods and procedures specified in paragraphs (g) and (h) of this
section, respectively, and shall not include emissions during the
following periods:
(1) Emissions during periods of start-up, shutdown, and malfunction,
as described in the Start-up, Shutdown, and Malfunction Plan.
(2) Emissions during periods of monitoring excursions, as defined in
Sec. 63.1334(d). For these periods, the calculation of monthly credits
and debits shall be adjusted as specified in paragraphs (f)(2)(i)
through (f)(2)(iii) of this section.
(i) No credits would be assigned to the credit-generating emission
point.
(ii) Maximum debits would be assigned to the debit-generating
emission point.
(iii) The owner or operator may demonstrate to the Administrator
that full or partial credits or debits should be assigned using the
procedures in paragraph (l) of this section.
(g) Debits are generated by the difference between the actual
emissions from a Group 1 emission point that is uncontrolled or is
controlled to a level less stringent than the applicable reference
control technology or standard and the emissions allowed for the Group 1
emission point. Said Group 1 emission points are identified in
paragraphs (c)(3) through (c)(5) of this section. Debits shall be
calculated as follows:
(1) Source-wide debits shall be calculated using Equation 28 of this
subpart. Debits and all terms of Equation 28 of this subpart are in
units of megagrams per month:

shall be after the final product recovery device, if any recovery
devices are present; before any control device (for continuous process
vents, recovery devices shall not be considered control devices); and
before discharge to the atmosphere. Method 1 or 1A, 40 CFR part 60,
appendix A, shall be used for selection of the sampling site.
[[Page 234]]
(ii) ECPViu for each continuous process vent i shall be
calculated using Equation 29 of this subpart.
[GRAPHIC] [TIFF OMITTED] TR12SE96.028
where:
ECPViu=Uncontrolled continuous process vent emission rate
from continuous process vent i, megagrams per month.
Q=Vent stream flow rate, dry standard cubic meters per minute, measured
using Method 2, 2A, 2C, or 2D, 40 CFR part 60, appendix A, as
appropriate.
h=Monthly hours of operation during which positive flow is present in

j as measured by Method 18, 40 CFR part 60, appendix A.

and shall be updated as provided in paragraph (g)(2)(ii)(B) of this
section.
(B) If there is a change in capacity utilization other than a change
in monthly operating hours, or if any other change is made to the
process or product recovery equipment or operation such that the
previously measured values of Q and Cj are no longer representative, a
new performance test shall be conducted to determine new representative
values of Q and Cj. These new values shall be used to calculate debits
and credits from the time of the change forward, and the new values

subpart.
[GRAPHIC] [TIFF OMITTED] TR12SE96.029
(1) The percent reduction shall be measured according to the

flare meeting the criteria in Sec. 63.116(a), or a boiler or process
heater meeting the criteria in Sec. 63.116(b), the percent reduction
shall be 98 percent. If a noncombustion control device is used, percent
reduction shall be demonstrated by a performance test at the inlet and

design evaluation and documented engineering calculations.
(2) For determining debits from Group 1 continuous process vents,
[[Page 235]]
product recovery devices shall not be considered control devices and
cannot be assigned a percent reduction in calculating
ECPViACTUAL. The sampling site for measurement of
uncontrolled emissions is after the final product recovery device.
However, as provided in Sec. 63.113(a)(3), a Group 1 continuous process
vent may add sufficient product recovery to raise the TRE index value
above 1.0 or, for Group 1 continuous process vents at an existing
affected source producing MBS, above 3.7, thereby becoming a Group 2
continuous process vent. Such a continuous process vent would not be a
Group 1 continuous process vent and would, therefore, not be included in
determining debits under this paragraph (g)(2)(iii)(B)(2).
(3) Procedures for calculating the percent reduction of pollution
prevention measures are specified in paragraph (j) of this section.
(3) Emissions from continuous process vents located in the

process vent, except that paragraph (g)(2)(iii)(B)(2) of this section
shall not apply and the sampling site shall be after those recovery
devices installed as part of normal operation; before any add-on control
devices (i.e., those required by regulation); and prior to discharge to
the atmosphere. Then, individual continuous process vent emissions shall
be summed to determine ECPVSjACTUAL.
(ii)(A) ECPVSjstd shall be calculated using Equation 31 of this
subpart.

within the affected source, as calculated according to paragraph
(g)(3)(ii)(B) of this section.
(B) The amount of polymer produced, Mg per month, for the collection
of process sections j within the affected source shall be determined by
determining the weight of polymer pulled from the process line(s) during
a 30-day period. The polymer produced shall be determined by direct
measurement or by an alternate methodology, such as materials balance.
If an alternate methodology is used, a description of the methodology,
including all procedures, data, and assumptions shall be submitted as
part of the Emissions Averaging Plan required by Sec. 63.1335(e)(4).
(C) Alternatively, ECPVSjstd for continuous process vents
located in the collection of process sections within the affected source
subject to Sec. 63.1316(c)(1) may be calculated using the procedures in
paragraph (g)(2)(i) and (g)(2)(ii) of this section to determine the
organic HAP emissions for each individual continuous process vent,
except that the sampling site shall be after recovery devices installed
as part of normal operation; before any add-on control devices (i.e.,
those required by regulation); and prior to discharge to the atmosphere.
Then, individual continuous process vent emissions shall be summed and
multiplied by 0.02 to determine ECPVSjstd.

procedures specified in Sec. 63.150(g)(3).

(B) If there is a change in capacity utilization other than a change
in monthly operating hours, or if any other change is made to the
process or product recovery equipment or operation such that the
previously measured values of Q and Cj are no longer
representative, a new performance test shall be conducted to determine
new representative values of Q and Cj. These new values shall
be used to calculate debits and credits from the time of the change
forward, and the new values shall be reported in the next Periodic
Report.
(iii) The following procedures and equations shall be used to
calculate EABViACTUAL:
(A) If the aggregate batch vent stream is not controlled by a
control device or pollution prevention measure, EABViACTUAL =
EABViu, where EABViu is calculated according to
the procedures in paragraphs (g)(7)(i) and (g)(7)(ii) of this section.

(i) The following procedures shall be followed to establish nominal
efficiencies for emission controls for storage vessels, continuous
process vents, and process wastewater streams. The procedures in
paragraphs (i)(1) through (i)(6) of this section shall be followed for
control technologies that are different in use or design from the
reference control technologies and achieve greater percent reductions
than the percent efficiencies assigned to the reference control
technologies in Sec. 63.111.
(1) In those cases where the owner or operator is seeking permission
to take credit for use of a control technology that is different in use
or design from the reference control technology, and the different
control technology will be used in more than three applications at a
single plant-site, the owner or operator shall submit the information
specified in paragraphs (i)(1)(i) through (i)(1)(iv) of this section, as
specified in Sec. 63.1335(e)(7)(ii), to the Director of the EPA Office
of Air Quality Planning and Standards in writing:
(i) Emission stream characteristics of each emission point to which
the control technology is or will be applied including the kind of
emission point, flow, organic HAP concentration, and all other stream
characteristics necessary to design the control technology or determine
its performance.
(ii) Description of the control technology including design
specifications.
(iii) Documentation demonstrating to the Administrator's
satisfaction the control efficiency of the control technology. This may
include performance test data collected using an appropriate EPA Method
or any other method validated according to Method 301, 40 CFR part 63,
appendix A, of this part. If it is infeasible to obtain test data,
documentation may include a design evaluation and calculations. The
engineering basis of the calculation procedures and all inputs and
assumptions made in the calculations shall be documented.
(iv) A description of the parameter or parameters to be monitored to
ensure that the control technology will be operated in conformance with
its design and an explanation of the criteria used for selection of that
parameter (or parameters).
(2) The Administrator shall determine within 120 days whether an
application presents sufficient information to determine nominal
efficiency. The Administrator reserves the right to request specific
data in addition to the items listed in paragraph (i)(1) of this
section.
(3) The Administrator shall determine within 120 days of the
submittal of sufficient data whether a control technology shall have a
nominal efficiency and the level of that nominal efficiency. If, in the
Administrator's judgment, the control technology achieves a level of
emission reduction greater than the reference control technology for a
particular kind of emission point, the Administrator will publish a
Federal Register notice establishing a nominal efficiency for the
control technology.
(4) The Administrator may grant permission to take emission credits
for use of the control technology. The Administrator may also impose
requirements that may be necessary to ensure operation and maintenance
to achieve the specified nominal efficiency.
(5) In those cases where the owner or operator is seeking permission
to take credit for use of a control technology that is different in use
or design from the reference control technology and the different
control technology will be used in no more than three applications at a
single plant site, the owner or operator shall submit the information
listed in paragraphs (i)(1)(i) through (i)(1)(iv) of this section, as
specified in Sec. 63.1335(e)(7)(ii), to the Administrator.
(i) In these instances, use and conditions for use of the control
technology may be approved by the permitting authority as part of an
operating permit
[[Page 244]]
application or modification. The permitting authority shall follow the
procedures specified in paragraphs (i)(2) through (i)(4) of this section
except that, in these instances, a Federal Register notice is not
required to establish the nominal efficiency for the different
technology.
(ii) If, in reviewing the application, the permitting authority
believes the control technology has broad applicability for use by other
affected sources, the permitting authority shall submit the information
provided in the application to the Director of the EPA Office of Air
Quality Planning and Standards. The Administrator shall review the
technology for broad applicability and may publish a Federal Register
notice; however, this review shall not affect the permitting authority's
approval of the nominal efficiency of the control technology for the
specific application.
(6) If, in reviewing an application for a control technology for an
emission point, the Administrator or permitting authority determines the
control technology is not different in use or design from the reference
control technology, the Administrator or permitting authority shall deny
the application.
(j) The following procedures shall be used for calculating the
efficiency (percent reduction) of pollution prevention measures for
storage vessels, continuous process vents, batch process vents,
aggregate batch vent streams, and wastewater streams:
(1) A pollution prevention measure is any practice that meets the
criteria of paragraphs (j)(1)(i) and (j)(1)(ii) of this section.
(i) A pollution prevention measure is any practice that results in a
lesser quantity of organic HAP emissions per unit of product released to
the atmosphere prior to out-of-process recycling, treatment, or control
of emissions, while the same product is produced.
(ii) Pollution prevention measures may include: substitution of
feedstocks that reduce organic HAP emissions; alterations to the
production process to reduce the volume of materials released to the
environment; equipment modifications; housekeeping measures; and in-
process recycling that returns waste materials directly to production as
raw materials. Production cutbacks do not qualify as pollution
prevention.
(2) The emission reduction efficiency of pollution prevention
measures implemented after November 15, 1990, may be used in calculating
the actual emissions from an emission point in the debit and credit
equations in paragraphs (g) and (h) of this section.
(i) For pollution prevention measures, the percent reduction used in
the equations in paragraphs (g)(2) through (g)(7) of this section and
paragraphs (h)(2) through (h)(7) of this section is the percent
difference between the monthly organic HAP emissions for each emission
point after the pollution prevention measure for the most recent month
versus monthly emissions from the same emission point before the
pollution prevention measure, adjusted by the volume of product produced
during the two monthly periods.
(ii) Equation 46 of this subpart shall be used to calculate the
percent reduction of a pollution prevention measure for each emission
point.
[GRAPHIC] [TIFF OMITTED] TR12SE96.045
where:
Percent reduction=Efficiency of pollution prevention measure (percent
organic HAP reduction).
EB=Monthly emissions before the pollution prevention measure,

as specified in either paragraphs (j)(2)(ii)(D) or (j)(2)(ii)(E) of this
section.
PB=Monthly production before the pollution prevention
measure, megagrams per month, during the same period over which
EB is calculated.
Ppp=Monthly production after the pollution prevention
measure, megagrams per month, as determined for the most recent month.
(A) The monthly emissions before the pollution prevention measure,
EB, shall be determined in a manner consistent with the
equations and procedures in paragraphs (g)(2) and (g)(3) of this section
for continuous process vents, paragraph (g)(4) of this section for
storage vessels, paragraph (g)(6) of this section for batch process
vents, and paragraph (g)(7) of this section for aggregate batch vent
streams.
(B) For wastewater, EB shall be calculated using Equation
47 of this subpart:
[GRAPHIC] [TIFF OMITTED] TR09MR99.011
Where:
n = Number of wastewater streams.
QBi = Annual average flow rate for wastewater stream i before
the pollution prevention measure, defined and determined according to
Sec. 63.144(c)(3), liters per minute, before implementation of the
pollution prevention measure.
HBi = Number of hours per month that wastewater stream i was
discharged before the pollution prevention measure, hours per month.
s = Total number of organic HAP in wastewater stream i.
Fem = Fraction emitted of organic HAP m in wastewater from
Table 34 of subpart G of this part, dimensionless.
HAPBim = Annual average concentration of organic HAP m in
wastewater stream i, defined and determined according to paragraph
Sec. 63.150(g)(5)(i) of this section, before the pollution prevention
measure, parts per million by weight, as measured before the
implementation of the pollution measure.
(C) If the pollution prevention measure was implemented prior to
September 12, 1996 records may be used to determine EB.
(D) The monthly emissions after the pollution prevention measure,
Epp, may be determined during a performance test or by a
design evaluation and documented engineering calculations. Once an
emissions-to-production ratio has been established, the ratio can be
used to estimate monthly emissions from monthly production records.
(E) For wastewater, Epp shall be calculated using
Equation 48 of this subpart and n, Qppi, Hppi, s,
Fem, and HAPppim are defined and determined as
described in paragraph (j)(2)(ii)(B) of this section, except that
Qppi, Hppi, and HAPppim shall be
determined after the pollution prevention measure has been implemented.
[GRAPHIC] [TIFF OMITTED] TR12SE96.047
(iii) All equations, calculations, test procedures, test results,
and other information used to determine the percent reduction achieved
by a pollution prevention measure for each emission point shall be fully
documented.
[[Page 246]]
(iv) The same pollution prevention measure may reduce emissions from
multiple emission points. In such cases, the percent reduction in
emissions for each emission point shall be calculated.
(v) For the purposes of the equations in paragraphs (h)(2) through
(h)(7) of this section used to calculate credits for emission points
controlled more stringently than the reference control technology or
standard, the nominal efficiency of a pollution prevention measure is
equivalent to the percent reduction of the pollution prevention measure.
When a pollution prevention measure is used, the owner or operator of an
affected source is not required to apply to the Administrator for a
nominal efficiency and is not subject to paragraph (i) of this section.
(k) The owner or operator shall demonstrate that the emissions from
the emission points proposed to be included in the emissions average
will not result in greater hazard or, at the option of the
Administrator, greater risk to human health or the environment than if
the emission points were controlled according to the provisions in
Secs. 63.1314, 63.1315, 63.1316 through 63.1320, 63.1321, and 63.1330.

to the satisfaction of the Administrator.
(i) The Administrator may require owners and operators to use
specific methodologies and procedures for making a hazard or risk
determination.
(ii) The demonstration and approval of hazard or risk equivalency
shall be made according to any guidance that the Administrator makes
available for use.

if an operating permit application has not yet been submitted.
(3) An Emissions Averaging Plan that does not demonstrate hazard or
risk equivalency to the satisfaction of the Administrator shall not be
approved. The Administrator may require such adjustments to the
Emissions Averaging Plan as are necessary in order to ensure that the
emissions average will not result in greater hazard or risk to human
health or the environment than would result if the emission points were
controlled according to Secs. 63.1314, 63.1315, 63.1316 through 63.1320,
63.1321, and 63.1330.

(i) Be a quantitative, bona fide chemical hazard or risk assessment;
(ii) Account for differences in chemical hazard or risk to human
health or the environment; and
(iii) Meet any requirements set by the Administrator for such
demonstrations.
(l) For periods of parameter monitoring excursions, an owner or
operator may request that the provisions of paragraphs (l)(1) through
(l)(4) of this section be followed instead of the procedures in
paragraphs (f)(2)(i) and (f)(2)(ii) of this section.
(1) The owner or operator shall notify the Administrator of
monitoring excursions in the Periodic Reports as required in
Sec. 63.1335(e)(6).
(2) The owner or operator shall demonstrate that other types of
monitoring data or engineering calculations are appropriate to establish
that the control device for the emission point was operating in such a
fashion to warrant assigning full or partial credits and debits. This
demonstration shall be made to the Administrator's satisfaction, and the
Administrator may establish procedures of demonstrating compliance that
are acceptable.
(3) The owner or operator shall provide documentation of the
excursion and the other type of monitoring data or engineering
calculations to be used to demonstrate that the control device for the
emission point was operating in such a fashion to warrant assigning full
or partial credits and debits.
(4) The Administrator may assign full or partial credit and debits
upon review of the information provided.
(m) For each emission point included in an emissions average, the
owner or operator shall perform testing, monitoring, recordkeeping, and
reporting equivalent to that required for Group 1 emission points
complying with Secs. 63.1314, 63.1315, 63.1316 through 63.1320, 63.1321,
and 63.1330, as applicable. The

episodes, or portions thereof, selected to be controlled are vented to
the control device.
(B) The average monitored parameter value shall be calculated for
each batch emission episode, or portion thereof, in the batch cycle
selected to be controlled. The average shall be based on all values
measured during the required performance test.
(C) If the level to be established is a maximum operating parameter,
the level shall be defined as the minimum of the average parameter
values of the batch emission episodes, or portions thereof, in the batch
cycle selected to be controlled.
(D) If the level to be established is a minimum operating parameter,
the level shall be defined as the maximum of the average parameter
values of the batch emission episodes, or portions thereof, in the batch
cycle selected to be controlled.
(E) Alternatively, an average monitored parameter value shall be
calculated for the entire batch cycle based on all values measured
during each batch emission episode, or portion thereof, selected to be
controlled.
(ii) Instead of establishing a single level for the batch cycle, as
described in paragraph (b)(3)(i) of this section, an owner or operator
may establish separate levels for each batch emission episode, or
portion thereof, selected to be controlled. Each level shall be
determined as specified in paragraphs (b)(3)(i)(A) and (b)(3)(i)(B) of
this section.
(iii) The batch cycle shall be defined in the Notification of
Compliance Status, as specified in Sec. 63.1335(e)(5). Said definition
shall include an identification of each batch emission episode and the
information required to determine parameter monitoring compliance for
partial batch cycles (i.e., when part of a batch cycle is accomplished
during two different operating days).
(4) Aggregate batch vent streams. For aggregate batch vent streams,
the monitoring level shall be established in accordance with paragraph
(b)(2) of this section.
(c) Establishment of parameter monitoring levels based on
performance tests, engineering assessments, and/or manufacturer's
recommendations. As required in
[[Page 251]]
paragraph (a) of this section, the information specified in paragraphs
(c)(2) and (c)(3) of this section shall be provided in the Precompliance
Report.
(1) Parameter monitoring levels established under this paragraph (c)
shall be based on the parameter values measured during the performance
test supplemented by engineering assessments and manufacturer's
recommendations. Performance testing is not required to be conducted
over the entire range of expected parameter values.
(2) The specific level of the monitored parameter(s) for each
emission point.
(3) The rationale for the specific level for each parameter for each
emission point, including any data and calculations used to develop the
level and a description of why the level indicates proper operation of
the control or recovery device.
(d) Establishment of parameter monitoring based on engineering
assessments and/or manufacturer's recommendations. If a performance test
is not required by this subpart for a control or recovery device, the
maximum or minimum level may be based solely on engineering assessments
and/or manufacturer's recommendations. As required in paragraph (a) of
this section, the determined level and all supporting documentation
shall be provided in the Precompliance Report.
(e) Compliance determinations. The provisions of this paragraph (e)
apply only to emission points and control or recovery devices for which
continuous monitoring is required under this subpart.
(1) The parameter monitoring data for storage vessels, process
vents, process wastewater streams, and emission points included in
emissions averages that are required to perform continuous monitoring
shall be used to determine compliance for the monitored control or
recovery devices.
(2) Except as provided in paragraphs (e)(3) and (g) of this section,
for each excursion, as defined in paragraph (f) of this section, the
owner or operator shall be deemed out of compliance with the provisions
of this subpart.
(3) If the daily average value of a monitored parameter is above the
maximum level or below the minimum level established, or if monitoring
data cannot be collected during monitoring device calibration check or
monitoring device malfunction, but the affected source is operated
during the periods of start-up, shutdown, or malfunction in accordance
with the affected source's Start-up, Shutdown, and Malfunction Plan,
then the event shall not be considered a monitoring parameter excursion.
(f) Parameter monitoring excursion definitions. (1) For storage
vessels, continuous process vents, aggregate batch vent streams, and
wastewater streams, an excursion means any of the three cases listed in
paragraphs (f)(1)(i) through (f)(1)(iii) of this section. For a control
or recovery device where multiple parameters are monitored, if one or
more of the parameters meets the excursion criteria in paragraphs
(f)(1)(i) through (f)(1)(iii) of this section, this is considered a
single excursion for the control or recovery device.
(i) When the daily average value of one or more monitored parameters
is above the maximum level or below the minimum level established for
the given parameters.
(ii) When the period of control or recovery device operation is 4
hours or greater in an operating day and monitoring data are
insufficient, as defined in paragraph (f)(1)(iv) of this section, to
constitute a valid hour of data for at least 75 percent of the operating
hours.
(iii) When the period of control or recovery device operation is
less than 4 hours in an operating day and more than two of the hours
during the period of operation do not constitute a valid hour of data
due to insufficient monitoring data, as defined in paragraph (f)(1)(iv)
of this section.
(iv) Monitoring data are insufficient to constitute a valid hour of
data, as used in paragraphs (f)(1)(ii) and (f)(1)(iii) of this section,
if measured values are unavailable for any of the 15-minute periods
within the hour. For data compression systems approved under
Sec. 63.1335(g)(3), monitoring data are insufficient to calculate a
valid hour of data if there are less than four data measurements made
during the hour.
(2) For batch process vents, an excursion means one of the two cases
listed
[[Page 252]]
in paragraphs (f)(2)(i) and (f)(2)(ii) of this section. For a control
device where multiple parameters are monitored, if one or more of the
parameters meets the excursion criteria in either paragraph (f)(2)(i) or
(f)(2)(ii) of this section, this is considered a single excursion for
the control device.
(i) When the batch cycle daily average value of one or more
monitored parameters is above the maximum or below the minimum
established level for the given parameters.
(ii) When monitoring data are insufficient. Monitoring data shall be
considered insufficient when measured values are not available for at
least 75 percent of the 15-minute periods when batch emission episodes,
or portions thereof, selected to be controlled are being vented to the
control device during the operating day.
(g) Excused excursions. A number of excused excursions shall be
allowed for each control or recovery device for each semiannual period.
The number of excused excursions for each semiannual period is specified
in paragraphs (g)(1) through (g)(6) of this section. This paragraph (g)
applies to affected sources required to submit Periodic Reports
semiannually or quarterly. The first semiannual period is the 6-month
period starting the date the Notification of Compliance Status is due.
(1) For the first semiannual period--six excused excursions.
(2) For the second semiannual period--five excused excursions.
(3) For the third semiannual period--four excused excursions.
(4) For the fourth semiannual period--three excused excursions.
(5) For the fifth semiannual period--two excused excursions.
(6) For the sixth and all subsequent semiannual periods--one excused
excursion.
Sec. 63.1335 General recordkeeping and reporting provisions.
(a) Data retention. Each owner or operator of an affected source
shall keep copies of all applicable records and reports required by this
subpart for at least 5 years, unless otherwise specified in this
subpart.
(b) Requirements of subpart A of this part. The owner or operator of
an affected source shall comply with the applicable recordkeeping and
reporting requirements in subpart A of this part as specified in Table 1

(1) Start-up, shutdown, and malfunction plan. The owner or operator
of an affected source shall develop and implement a written start-up,
shutdown, and malfunction plan as specified in Sec. 63.6(e)(3). This
plan shall describe, in detail, procedures for operating and maintaining
the affected source during periods of start-up, shutdown, and
malfunction and a program for corrective action for malfunctioning
process and air pollution control equipment used to comply with this
subpart. The affected source shall keep this plan onsite and shall
incorporate it by reference into their operating permit. Records
associated with the plan shall be kept as specified in paragraphs
(b)(1)(i)(A) through (b)(1)(i)(D) of this section. Reports related to
the plan shall be submitted as specified in paragraph (b)(1)(ii) of this
section.
(i) Records of start-up, shutdown, and malfunction. The owner or
operator shall keep the records specified in paragraphs (b)(1)(i)(A)
through (b)(1)(i)(D) of this section.
(A) Records of the occurrence and duration of each malfunction of
air pollution control equipment or continuous monitoring systems used to
comply with this subpart.
(B) For each start-up, shutdown, or malfunction, a statement that
the procedures specified in the affected source's start-up, shutdown,
and malfunction plan were followed; alternatively, documentation of any
actions taken that are not consistent with the plan.
(C) For continuous monitoring systems used to comply with this
subpart, records documenting the completion of calibration checks and
maintenance of continuous monitoring systems that are specified in the
manufacturer's instructions.
(D) Records specified in paragraphs (b)(1)(i)(B) and (b)(1)(i)(C) of
this section are not required if they pertain solely to Group 2 emission
points that
[[Page 253]]
are not included in an emissions average or to Group 2 continuous
process vents subject to Sec. 63.1315(a) with a total resource
effectiveness value greater than 4.0 or, for Group 2 continuous process
vents subject to Sec. 63.1315(b), with a total resource effectiveness
value greater than 6.7.
(ii) Reports of start-up, shutdown, and malfunction. For the
purposes of this subpart, the semiannual start-up, shutdown, and
malfunction reports shall be submitted on the same schedule as the
Periodic Reports required under paragraph (e)(6) of this section instead
of the schedule specified in Sec. 63.10(d)(5)(i). Said reports shall
include the information specified in paragraphs (b)(1)(i)(A) through
(b)(1)(i)(C) of this section and shall contain the name, title, and
signature of the owner or operator or other responsible official who is
certifying its accuracy.
(2) Application for approval of construction or reconstruction. For
new affected sources, each owner or operator shall comply with the
provisions in Sec. 63.5 regarding construction and reconstruction,
excluding the provisions specified in Sec. 63.5 (d)(1)(ii)(H), (d)(2),
and (d)(3)(ii).
(c) Requirements of subpart H of this part. Owners or operators of
affected sources shall comply with the reporting and recordkeeping
requirements in subpart H of this part, except as specified in
Sec. 63.1331.
(d) Recordkeeping and documentation. Owners or operators required to
keep continuous records shall keep records as specified in paragraphs
(d)(1) through (d)(8) of this section, unless an alternative
recordkeeping system has been requested and approved as specified in
paragraph (g) or (h) of this section. Documentation requirements are
specified in paragraphs (d)(9) and (d)(10) of this section.
(1) The monitoring system shall measure data values at least once
every 15 minutes.
(2) The owner or operator shall record either each measured data
value or block average values for 1 hour or shorter periods calculated
from all measured data values during each period. If values are measured
more frequently than once per minute, a single value for each minute may
be used to calculate the hourly (or shorter period) block average
instead of all measured values. Owners or operators of batch process
vents must record each measured data value.
(3) Daily average (or batch cycle daily average) values of each
continuously monitored parameter shall be calculated for each operating
day as specified in paragraphs (d)(3)(i) through (d)(3)(ii) of this
section, except as specified in paragraph (d)(6) of this section.
(i) The daily average value or batch cycle daily average shall be
calculated as the average of all parameter values recorded during the
operating day. As specified in Sec. 63.1326(e)(2)(i), only parameter
values measured during those batch emission episodes, or portions
thereof, in the batch cycle that the owner or operator has chosen to
control shall be used to calculate the average. The calculated average
shall cover a 24-hour period if operation is continuous, or the number
of hours of operation per operating day if operation is not continuous.
(ii) The operating day shall be the period the owner or operator
specifies in the operating permit or the Notification of Compliance
Status. It may be from midnight to midnight or another 24-hour period.
(4) Records required when out of compliance. If the daily average
(or batch cycle daily average) value of a monitored parameter for a
given operating day is below the minimum level or above the maximum
level established in the Notification of Compliance Status or operating
permit, the owner or operator shall retain the data recorded that
operating day under paragraph (d)(2) of this section.
(5) Records required when in compliance for daily average value or
batch cycle daily average value. If the daily average (or batch cycle
daily average) value of a monitored parameter for a given operating day
is above the minimum level or below the maximum level established in the
Notification of Compliance Status or operating permit, the owner or
operator shall either:
(i) Retain block average values for 1 hour or shorter periods for
that operating day; or
(ii) Retain the data recorded in paragraph (d)(2) of this section.
[[Page 254]]
(6) Records required when all recorded values are in compliance. If
all recorded values for a monitored parameter during an operating day
are above the minimum level or below the maximum level established in
the Notification of Compliance Status or operating permit, the owner or
operator may record that all values were above the minimum level or
below the maximum level rather than calculating and recording a daily
average (or batch cycle daily average) for that operating day. For these
operating days, the records required in paragraph (d)(5) of this section
shall also be retained for 5 years.
(7) Monitoring data recorded during periods of monitoring system
breakdowns, repairs, calibration checks, and zero (low-level) and high-
level adjustments shall not be included in any average computed under
this subpart. Records shall be kept of the times and durations of all
such periods.
(8) In addition to the periods specified in paragraph (d)(7) of this
section, records shall be kept of the times and durations of any other
periods during process operation or control device operation when
monitors are not operating. For batch process vents, this paragraph
(d)(8) only applies during batch emission episodes, or portions thereof,
that the owner or operator has selected to control.
(9) For each TPPU that is not part of the affected source because it
does not use as a reactant or process solvent, or produce as a by-
product or co-product any organic HAP, the owner or operator shall
maintain the documentation specified in Sec. 63.1310(b)(1).
(10) For each flexible operation unit in which the primary product
is determined to be something other than a thermoplastic product, the
owner or operator shall maintain the documentation specified in
Sec. 63.1310(f)(6).
(e) Reporting and notification. (1) In addition to the reports and
notifications required by subparts A and H of this part, as specified in
this subpart, the owner or operator of an affected source shall prepare
and submit the reports listed in paragraphs (e)(3) through (e)(8) of
this section, as applicable.
(2) All reports required under this subpart shall be sent to the
Administrator at the addresses listed in Sec. 63.13. If acceptable to
both the Administrator and the owner or operator of an affected source,
reports may be submitted on electronic media.
(3) Precompliance Report. Affected sources requesting an extension
for compliance, or requesting approval to use alternative monitoring
parameters, alternative continuous monitoring and recordkeeping, or
alternative controls, shall submit a Precompliance Report according to
the schedule described in paragraph (e)(3)(i) of this section. The
Precompliance Report shall contain the information specified in
paragraphs (e)(3)(ii) through (e)(3)(vi) of this section, as
appropriate.
(i) Submittal dates. The Precompliance Report shall be submitted to
the Administrator no later than 12 months prior to the compliance date.

the Administrator with the application for approval of construction or
reconstruction required in paragraph (b)(2) of this section.
(ii) A request for an extension for compliance must be submitted in
the Precompliance Report, if it has not been submitted to the operating
permit authority as part of the operating permit application. The
request for a compliance extension will include the data outlined in
Sec. 63.6(i)(6)(i) (A), (B), and (D), as required in Sec. 63.1311(e)(1).
(iii) The alternative monitoring parameter information required in
paragraph (f) of this section shall be submitted if, for any emission
point, the owner or operator of an affected source seeks to comply
through the use of a control technique other than those for which
monitoring parameters are specified in this subpart or in subpart G of
this part or seeks to comply by monitoring a different parameter than
those specified in this subpart or in subpart G of this part.
(iv) If the affected source seeks to comply using alternative
continuous monitoring and recordkeeping as specified in paragraph (g) of
this section, the information requested in paragraph (e)(3)(iv)(A) or
(e)(3)(iv)(B) of this section must be submitted in the Precompliance
Report.
[[Page 255]]
(A) The owner or operator must submit notification of the intent to
use the provisions specified in paragraph (g) of this section; or
(B) The owner or operator must submit a request for approval to use
alternative continuous monitoring and recordkeeping provisions as
specified in paragraph (g) of this section.
(v) The owner or operator shall report the intent to use alternative
controls to comply with the provisions of this subpart. Alternative
controls must be deemed by the Administrator to be equivalent to the
controls required by the standard, under the procedures outlined in
Sec. 63.6(g).
(vi) If an owner or operator demonstrates that the emissions
estimation equations contained in Sec. 63.1323(b) are inappropriate as

(4) Emissions Averaging Plan. For all existing affected sources
using emissions averaging, an Emissions Averaging Plan shall be
submitted for approval according to the schedule and procedures
described in paragraph (e)(4)(i) of this section. The Emissions
Averaging Plan shall contain the information specified in paragraph
(e)(4)(ii) of this section, unless the information required in paragraph
(e)(4)(ii) of this section is submitted with an operating permit
application. An owner or operator of an affected source who submits an
operating permit application instead of an Emissions Averaging Plan
shall submit the information specified in paragraph (e)(8) of this
section. In addition, a supplement to the Emissions Averaging Plan, as
required under paragraph (e)(4)(iii) of this section, is to be submitted
whenever alternative controls or operating scenarios may be used to
comply with this subpart. Updates to the Emissions Averaging Plan shall
be submitted in accordance with paragraph (e)(4)(iv) of this section.
(i) Submittal and approval. The Emissions Averaging Plan shall be
submitted no later than 18 months prior to the compliance date, and it
is subject to Administrator approval. The Administrator shall determine
within 120 operating days whether the Emissions Averaging Plan submitted
presents sufficient information. The Administrator shall either approve
the Emissions Averaging Plan, request changes, or request that the owner
or operator submit additional information. Once the Administrator
receives sufficient information, the Administrator shall approve,
disapprove, or request changes to the plan within 120 operating days.

expected date of application.
(D) The required information shall include the specific
identification of each emission point affected by a pollution prevention
measure. To be considered a pollution prevention measure, the criteria
in Sec. 63.1332(j)(1) must be met. If the same pollution prevention
measure reduces or eliminates emissions from multiple emission points in
the average, the owner or operator
[[Page 256]]
must identify each of these emission points.
(E) The required information shall include a statement that the
compliance demonstration, monitoring, inspection, recordkeeping, and
reporting provisions in Sec. 63.1332 (m), (n), and (o) that are
applicable to each emission point in the emissions average will be

values at least once every 15 minutes and that does not generate
continuous records may request approval to use a nonautomated system
with less frequent monitoring, in accordance with paragraphs (g)(2)(i)
and (g)(2)(ii) of this section.
(i) The requested system shall include manual reading and recording
of the value of the relevant operating parameter no less frequently than
once per hour. Daily average (or batch cycle daily average) values shall
be calculated from these hourly values and recorded.
(ii) The request shall contain:
(A) A description of the planned monitoring and recordkeeping
system;
(B) Documentation that the affected source does not have an
automated monitoring and recording system;
(C) Justification for requesting an alternative monitoring and
recordkeeping system; and
(D) Demonstration to the Administrator's satisfaction that the
proposed monitoring frequency is sufficient to represent control or
recovery device operating conditions, considering typical variability of
the specific process and control or recovery device operating parameter
being monitored.
(3) An owner or operator may request approval to use an automated
data compression recording system that does not record monitored
operating parameter values at a set frequency (for example, once every
15 minutes) but records all values that meet set criteria for variation
from previously recorded values, in accordance with paragraphs (g)(3)(i)
and (g)(3)(ii) of this section.
(i) The requested system shall be designed to:
(A) Measure the operating parameter value at least once every 15
minutes;
(B) Except for the monitoring of batch process vents, calculate
hourly average values each hour during periods of operation;
(C) Record the date and time when monitors are turned off or on;
(D) Recognize unchanging data that may indicate the monitor is not
functioning properly, alert the operator, and record the incident;
[[Page 264]]
(E) Calculate daily average (or batch cycle daily average) values of
the monitored operating parameter based on all measured data; and
(F) If the daily average is not an excursion, as defined in
Sec. 63.1334(f), the data for that operating day may be converted to
hourly average values and the four or more individual records for each
hour in the operating day may be discarded.
(ii) The request shall contain:
(A) A description of the monitoring system and data compression
recording system, including the criteria used to determine which
monitored values are recorded and retained;
(B) The method for calculating daily averages and batch cycle daily
averages; and
(C) A demonstration that the system meets all criteria in paragraph
(g)(3)(i) of this section.

any item of equipment, the owner or operator may implement the
recordkeeping requirements specified in paragraph (h)(1) or (h)(2) of
this section as alternatives to the provisions specified in Sec. 63.1314
for storage vessels, Sec. 63.1315 or 63.1317, as appropriate, for
continuous process vents, Sec. 63.1321 for batch process vents and
aggregate batch vent streams, or Sec. 63.1330 for wastewater. The owner
or operator shall retain for a period of 5 years each record required by
paragraph (h)(1) or (h)(2) of this section.
(1) The owner or operator may retain only the daily average (or
batch cycle daily average) value, and is not required to retain more
frequent monitored operating parameter values, for a monitored parameter
with respect to an item of equipment, if the requirements of paragraphs
(h)(1)(i) through (h)(1)(vi) of this section are met. An owner or
operator electing to comply with the requirements of paragraph (h)(1) of
this section shall notify the Administrator in the Notification of
Compliance Status or, if the Notification of Compliance Status has
already been submitted, in the Periodic Report immediately preceding
implementation of the requirements of paragraph (h)(1) of this section.
(i) The monitoring system is capable of detecting unrealistic or
impossible data during periods of operation other than start-ups,
shutdowns, or malfunctions (e.g., a temperature reading of -200 deg.C
on a boiler), and will alert the operator by alarm or other means. The
owner or operator shall record the occurrence. All instances of the
alarm or other alert in an operating day constitute a single occurrence.
(ii) The monitoring system generates, updated at least hourly
throughout each operating day, a running average of the monitoring
values that have been obtained during that operating day, and the
capability to observe this running average is readily available to the
Administrator on-site during the operating day. The owner or operator
shall record the occurrence of any period meeting the criteria in
paragraphs (h)(1)(ii)(A) through (h)(1)(ii)(C) of this section. All
instances in an operating day constitute a single occurrence.
(A) The running average is above the maximum or below the minimum
established limits;
(B) The running average is based on at least six 1-hour periods; and
(C) The running average reflects a period of operation other than a
start-up, shutdown, or malfunction.
(iii) The monitoring system is capable of detecting unchanging data
during periods of operation other than start-ups, shutdowns, or
malfunctions, except in circumstances where the presence of unchanging
data is the expected operating condition based on past experience (e.g.,
pH in some scrubbers), and will alert the operator by alarm or other
means. The owner or operator shall record the occurrence. All instances
of the alarm or other alert in an operating day constitute a single
occurrence.
(iv) The monitoring system will alert the owner or operator by an
alarm, if the running average parameter value calculated under paragraph
(h)(1)(ii) of this section reaches a set point that is appropriately
related to the established limit for the parameter that is being
monitored.
[[Page 265]]
(v) The owner or operator shall verify the proper functioning of the
monitoring system, including its ability to comply with the requirements
of paragraph (h)(1) of this section, at the times specified in
paragraphs (h)(1)(v)(A) through (h)(1)(v)(C). The owner or operator
shall document that the required verifications occurred.
(A) Upon initial installation.
(B) Annually after initial installation.
(C) After any change to the programming or equipment constituting
the monitoring system, which might reasonably be expected to alter the
monitoring system's ability to comply with the requirements of this
section.
(vi) The owner or operator shall retain the records identified in
paragraphs (h)(1)(vi)(A) through (h)(1)(vi)(C) of this section.
(A) Identification of each parameter, for each item of equipment,
for which the owner or operator has elected to comply with the
requirements of paragraph (h) of this section.
(B) A description of the applicable monitoring system(s), and of how
compliance will be achieved with each requirement of paragraphs
(h)(1)(i) through (h)(1)(v) of this section. The description shall
identify the location and format (e.g., on-line storage, log entries)
for each required record. If the description changes, the owner or
operator shall retain both the current and the most recent superseded
description.
(C) A description, and the date, of any change to the monitoring
system that would reasonably be expected to affect its ability to comply
with the requirements of paragraph (h)(1) of this section.
(2) If an owner or operator has elected to implement the
requirements of paragraph (h)(1) of this section for a monitored
parameter with respect to an item of equipment and a period of 6
consecutive months has passed without an excursion as defined in
paragraph (h)(2)(iv) of this section, the owner or operator is no longer
required to record the daily average (or batch cycle daily average)
value for any operating day when the daily average (or batch cycle daily
average) value is less than the maximum or greater than the minimum
established limit. With approval by the Administrator, monitoring data
generated prior to the compliance date of this subpart shall be credited
toward the period of 6 consecutive months, if the parameter limit and
the monitoring accomplished during the period prior to the compliance
date was required and/or approved by the Administrator.
(i) If the owner or operator elects not to retain the daily average
(or batch cycle daily average) values, the owner or operator shall
notify the Administrator in the next Periodic Report. The notification
shall identify the parameter and unit of equipment.
(ii) If, on any operating day after the owner or operator has ceased
recording daily average (or batch cycle daily average) values as
provided in paragraph (h)(2) of this section, there is an excursion as
defined in paragraph (h)(2)(iv) of this section, the owner or operator
shall immediately resume retaining the daily average (or batch cycle
daily average) value for each operating day and shall notify the
Administrator in the next Periodic Report. The owner or operator shall
continue to retain each daily average (or batch cycle daily average)
value until another period of 6 consecutive months has passed without an
excursion as defined in paragraph (h)(2)(iv) of this section.
(iii) The owner or operator shall retain the records specified in
paragraphs (h)(1)(i), (h)(1)(ii), and (h)(1)(vi) of this section, for
the duration specified in paragraph (h) of this section. For any
calendar week, if compliance with paragraphs (h)(1)(i) through
(h)(1)(iv) of this section does not result in retention of a record of
at least one occurrence or measured parameter value, the owner or

the provisions of this subpart apply to each new and existing portland
cement plant which is a major source or an area source as defined in
Sec. 63.2.
(b) The affected sources subject to this subpart are:
(1) Each kiln and each in-line kiln/raw mill at any major or area
source, including alkali bypasses, except for kilns and in-line kiln/raw
mills that burn hazardous waste and are subject to and regulated under
subpart EEE of this part;
(2) Each clinker cooler at any portland cement plant which is a
major source;

Sec. 63.1341 Definitions.
All terms used in this subpart that are not defined in this section
have the meaning given to them in the CAA and in subpart A of this part.
Alkali bypass means a duct between the feed end of the kiln and the
preheater tower through which a portion of the kiln exit gas stream is
withdrawn and quickly cooled by air or water to avoid excessive buildup
of alkali, chloride and/or sulfur on the raw feed. This may also be
referred to as the ``kiln exhaust gas bypass''.
Bagging system means the equipment which fills bags with portland
cement.
Clinker cooler means equipment into which clinker product leaving
the kiln is placed to be cooled by air supplied by a forced draft or
natural draft supply system.
Continuous monitor means a device which continuously samples the
regulated parameter specified in Sec. 63.1350 of this subpart without
interruption, evaluates the detector response at least once every 15
seconds, and computes and records the average value at least every 60
seconds, except during allowable periods of calibration and except as
defined otherwise by the continuous emission monitoring system
performance specifications in appendix B to part 60 of this chapter.
Conveying system means a device for transporting materials from one
piece of equipment or location to another location within a facility.
Conveying systems include but are not limited to the following: feeders,
belt conveyors,
[[Page 274]]
bucket elevators and pneumatic systems.
Conveying system transfer point means a point where any material
including but not limited to feed material, fuel, clinker or product, is
transferred to or from a conveying system, or between separate parts of
a conveying system.
Dioxins and furans (D/F) means tetra-, penta-, hexa-, hepta-,
and octa-chlorinated dibenzo dioxins and furans.
Facility means all contiguous or adjoining property that is under
common ownership or control, including properties that are separated
only by a road or other public right-of-way.
Feed means the prepared and mixed materials, which include but are
not limited to materials such as limestone, clay, shale, sand, iron ore,
mill scale, cement kiln dust and flyash, that are fed to the kiln. Feed
does not include the fuels used in the kiln to produce heat to form the
clinker product.
Finish mill means a roll crusher, ball and tube mill or other size
reduction equipment used to grind clinker to a fine powder. Gypsum and
other materials may be added to and blended with clinker in a finish
mill. The finish mill also includes the air separator associated with
the finish mill.
Greenfield kiln, in-line kiln/raw mill, or raw material dryer means
a kiln, in-line kiln/raw mill, or raw material dryer for which
construction is commenced at a plant site (where no kilns and no in-line
kiln/raw mills were in operation at any time prior to March 24, 1998)
after March 24, 1998.
Hazardous waste is defined in Sec. 261.3 of this chapter.
In-line kiln/raw mill means a system in a portland cement production
process where a dry kiln system is integrated with the raw mill so that
all or a portion of the kiln exhaust gases are used to perform the
drying operation of the raw mill, with no auxiliary heat source used. In
this system the kiln is capable of operating without the raw mill
operating, but the raw mill cannot operate without the kiln gases, and
consequently, the raw mill does not generate a separate exhaust gas
stream.
Kiln means a device, including any associated preheater or
precalciner devices, that produces clinker by heating limestone and
other materials for subsequent production of portland cement.
Kiln exhaust gas bypass means alkali bypass.
Monovent means an exhaust configuration of a building or emission
control device (e. g. positive pressure fabric filter) that extends the
length of the structure and has a width very small in relation to its
length (i. e., length to width ratio is typically greater than 5:1). The
exhaust may be an open vent with or without a roof, louvered vents, or a
combination of such features.
New brownfield kiln, in-line kiln raw mill, or raw material dryer
means a kiln, in-line kiln/raw mill or raw material dryer for which
construction is commenced at a plant site (where kilns and/or in-line
kiln/raw mills were in operation prior to March 24, 1998) after March
24, 1998.
One-minute average means the average of thermocouple or other sensor
responses calculated at least every 60 seconds from responses obtained
at least once during each consecutive 15 second period.
Portland cement plant means any facility manufacturing portland
cement.
Raw material dryer means an impact dryer, drum dryer, paddle-
equipped rapid dryer, air separator, or other equipment used to reduce
the moisture content of feed materials.
Raw mill means a ball and tube mill, vertical roller mill or other
size reduction equipment, that is not part of an in-line kiln/raw mill,
used to grind feed to the appropriate size. Moisture may be added or
removed from the feed during the grinding operation. If the raw mill is
used to remove moisture from feed materials, it is also, by definition,
a raw material dryer. The raw mill also includes the air separator
associated with the raw mill.
Rolling average means the average of all one-minute averages over
the averaging period.
Run average means the average of the one-minute parameter values for
a run.
TEQ means the international method of expressing toxicity
equivalents for dioxins and furans as defined in U.S. EPA, Interim
Procedures for Estimating Risks Associated with Exposures to Mixtures of
Chlorinated Dibenzo-p-dioxins and -dibenzofurans
