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, 2001), 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.

owner/operator using a wet scrubbing emission control system must
maintain three-hour averages of the pressure drop across each scrubber
and of the flow rate of the scrubbing liquid to each scrubber within the
allowable ranges established pursuant to the requirements of
Sec. 63.605(d)(1) or (2).
Sec. 63.605 Monitoring requirements.
(a) Each owner or operator of a new or existing wet-process
phosphoric acid process line, superphosphoric acid process line,
phosphate rock dryer, or phosphate rock calciner subject to the
provisions of this subpart shall install, calibrate, maintain, and
operate a monitoring system which can be used to determine and
permanently record the mass flow of phosphorus-bearing feed material to
the process. The monitoring system shall have an accuracy of
5 percent over its operating range.
(b)(1) Each owner or operator of a new or existing wet-process
phosphoric acid process line or superphosphoric acid process line
subject to the provisions of this subpart shall maintain a daily record
of equivalent P2O5 feed by first determining the
total mass rate in metric ton/hour of phosphorus bearing feed using a
monitoring system for measuring mass flowrate which meets the
requirements of paragraph (a) of this section and then by proceeding
according to Sec. 63.606(c)(3).
(2) Each owner or operator of a new or existing phosphate rock
calciner or phosphate rock dryer subject to the provisions of this
subpart shall maintain a daily record of phosphate rock feed by
determining the total mass rate in metric ton/hour of phosphorus bearing
feed using a monitoring system for measuring mass flowrate which meets
the requirements of paragraph (a) of this section.
(c) Each owner or operator of a new or existing wet-process
phosphoric acid process line, superphosphoric acid process line,
phosphate rock dryer or phosphate rock calciner using a wet scrubbing
emission control system shall install, calibrate, maintain, and operate
the following monitoring systems:
(1) A monitoring system which continuously measures and permanently
records the pressure drop across each scrubber in the process scrubbing
system in 15-minute block averages. The monitoring system shall be
certified by the manufacturer to have an accuracy of 5
percent over its operating range.
(2) A monitoring system which continuously measures and permanently
records the flow rate of the scrubbing liquid to each scrubber in the

system shall be certified by the manufacturer to have an accuracy of
5 percent over its operating range.
(d) Following the date on which the performance test required in
Sec. 63.606 is completed, the owner or operator of a new or existing
affected source using a wet scrubbing emission control system and
subject to emissions limitations for total fluorides or particulate
matter contained in this subpart must establish allowable ranges for
operating parameters using the methodology of either paragraph (d)(1) or
(2) of this section:
(1) The allowable range for the daily averages of the pressure drop
across each scrubber and of the flow rate of the scrubbing liquid to
each scrubber in the process scrubbing system is 20 percent
of the baseline average value determined as a requirement of
Sec. 63.606(c)(4), (d)(4), or (e)(2). The Administrator retains the
right to reduce the 20 percent adjustment to the baseline
average values of operating ranges in those instances where performance
test results indicate that a source's level of emissions is near the
value of an applicable emissions standard, but, in no instance shall the
adjustment be reduced to less than 10 percent. The owner or
operator must notify the Administrator of the baseline average value and
must notify the Administrator each time that the baseline value is
changed as a result of the most recent performance test. The
[[Page 14]]
baseline average values used for compliance shall be based on the values
determined during the most recent performance test. The new baseline
average value shall be effective on the date following the performance
test.
(2) The owner or operator of any new or existing affected source
shall establish, and provide to the Administrator for approval,
allowable ranges of baseline average values for the pressure drop across
and of the flow rate of the scrubbing liquid to each scrubber in the
process scrubbing system for the purpose of assuring compliance with
this subpart. Allowable ranges may be based upon baseline average values
recorded during previous performance tests using the test methods
required in this subpart and established in the manner required in
Sec. 63.606(c)(4), (d)(4), or (e)(2). As an alternative, the owner or
operator can establish the allowable ranges of baseline average values
using the results of performance tests conducted specifically for the
purposes of this paragraph using the test methods required in this
subpart and established in the manner required in Sec. 63.606(c)(4),
(d)(4), or (e)(2). The source shall certify that the control devices and
processes have not been modified subsequent to the testing upon which
the data used to establish the allowable ranges were obtained. The
allowable ranges of baseline average values developed pursuant to the
provisions of this paragraph must be submitted to the Administrator for
approval. The owner or operator must request and obtain approval of the
Administrator for changes to the allowable ranges of baseline values.
When a source using the methodology of this paragraph is retested, the
owner operator shall determine new allowable ranges of baseline average
values unless the retest indicates no change in the operating parameters
from previous tests. Any new allowable ranges of baseline average values
resulting from the most recent performance test shall be effective on
the date following the retest. Until changes to allowable ranges of
baseline average values are approved by the Administrator, the allowable
ranges for use in Sec. 63.604 shall be based upon the range of baseline
average values proposed for approval.
(e) Each owner or operator of a new or existing purified phosphoric
acid process line shall:
(1) Install, calibrate, maintain, and operate a monitoring system
which continuously measures and permanently records the stack gas exit
temperature for each chiller stack.
(2) Measure and record the concentration of methyl isobutyl ketone
in each product acid stream and each raffinate stream once daily.

and of the flow rate of the scrubbing liquid to each scrubber within the
allowable ranges established pursuant to the requirements of
Sec. 63.625(f)(1) or (2).
Sec. 63.625 Monitoring requirements.
(a) Each owner or operator of a new or existing diammonium and/or
monoammonium phosphate process line or granular triple superphosphate
process line subject to the provisions of this subpart shall install,
calibrate, maintain, and operate a monitoring system which can be used

according to Sec. 63.626(c)(3).
(c) Each owner or operator of a new or existing diammonium and/or
monoammonium phosphate process line, granular triple superphosphate
process line, or granular triple superphosphate storage building using a
wet scrubbing emission control system shall install, calibrate,
maintain, and operate the following monitoring systems:
(1) A monitoring system which continuously measures and permanently
records the pressure drop across each scrubber in the process scrubbing
system in 15-minute block averages. The monitoring system shall be
certified by the manufacturer to have an accuracy of 5
percent over its operating range.
(2) A monitoring system which continuously measures and permanently
records the flow rate of the scrubbing liquid to each scrubber in the
process scrubbing system in 15-minute block averages. The monitoring
system shall be certified by the manufacturer to have an accuracy of
5 percent over its operating range.
(d) The owner or operator of any granular triple superphosphate
storage building subject to the provisions of this subpart shall
maintain an accurate account of granular triple superphosphate in
storage to permit the determination of the amount of equivalent
P2O5 stored.
(e)(1) Each owner or operator of a new or existing granular triple
superphosphate storage building subject to the provisions of this
subpart shall maintain a daily record of total equivalent
P2O5 stored by multiplying the percentage
P2O5 content, as determined
[[Page 22]]
by Sec. 63.626(d)(3), times the total mass of granular triple
superphosphate stored.
(2) The owner or operator of any granular triple superphosphate
storage building subject to the provisions of this subpart shall develop
for approval by the Administrator a site-specific methodology including
sufficient recordkeeping for the purposes of demonstrating compliance
with Sec. 63.622(c)(2) or Sec. 63.623(c)(2), as applicable.
(f) Following the date on which the performance test required in
Sec. 63.626 is completed, the owner or operator of a new or existing
affected source using a wet scrubbing emission control system and
subject to emissions limitations for total fluorides or particulate
matter contained in this subpart must establish allowable ranges for
operating parameters using the methodology of either paragraph (f)(1) or
(2) of this section:
(1) The allowable range for the daily averages of the pressure drop
across each scrubber and of the flow rate of the scrubbing liquid to
each scrubber in the process scrubbing system is 20 percent
of the baseline average value determined as a requirement of
Sec. 63.626(c)(4) or (d)(4). The Administrator retains the right to
reduce the 20 percent adjustment to the baseline average
values of operating ranges in those instances where performance test
results indicate that a source's level of emissions is near the value of
an applicable emissions standard, but, in no instance shall the
adjustment be reduced to less than 10 percent. The owner or
operator must notify the Administrator of the baseline average value and
must notify the Administrator each time that the baseline value is
changed as a result of the most recent performance test. The baseline
average values used for compliance shall be based on the values
determined during the most recent performance test. The new baseline
average value shall be effective on the date following the performance
test.
(2) The owner or operator of any new or existing affected source
shall establish, and provide to the Administrator for approval,
allowable ranges of baseline average values for the pressure drop across
and of the flow rate of the scrubbing liquid to each scrubber in the
process scrubbing system for the purpose of assuring compliance with
this subpart. Allowable ranges may be based upon baseline average values
recorded during previous performance tests using the test methods
required in this subpart and established in the manner required in
Sec. 63.626(c)(4) or (d)(4). As an alternative, the owner or operator
can establish the allowable ranges of baseline average values using the
results of performance tests conducted specifically for the purposes of
this paragraph using the test methods required in this subpart and
established in the manner required in Sec. 63.626(c)(4) or (d)(4). The
source shall certify that the control devices and processes have not
been modified subsequent to the testing upon which the data used to
establish the allowable ranges were obtained. The allowable ranges of
baseline average values developed pursuant to the provisions of this
paragraph must be submitted to the Administrator for approval. The owner
or operator must request and obtain approval of the Administrator for
changes to the allowable ranges of baseline average values. When a
source using the methodology of this paragraph is retested, the owner
operator shall determine new allowable ranges of baseline average values
unless the retest indicates no change in the operating parameters from
previous tests. Any new allowable ranges of baseline average values
resulting from the most recent performance test shall be effective on
the date following the retest. Until changes to allowable ranges of
baseline average values are approved by the Administrator, the allowable
ranges for use in Sec. 63.624 shall be based upon the range of baseline
average values proposed for approval.
Sec. 63.626 Performance tests and compliance provisions.
(a)(1) On or before the applicable compliance date in Sec. 63.630
and once per annum thereafter, each owner or operator of a phosphate
fertilizers production plant subject to the provisions of this subpart
shall conduct a performance test to demonstrate compliance with the
applicable emission standard for each existing diammonium and/or
[[Page 23]]
monoammonium phosphate process line, granular triple superphosphate
process line, or granular triple superphosphate storage building. The
owner or operator shall conduct the performance test according to the
procedures in subpart A of this part and in this section.
(2) As required by Sec. 63.7(a)(2) and once per annum thereafter,
each owner or operator of a phosphate fertilizers production plant
subject to the provisions of this subpart shall conduct a performance
test to demonstrate compliance with the applicable emission standard for
each new diammonium and/or monoammonium phosphate process line, granular
triple superphosphate process line, or granular triple superphosphate
storage building. The owner or operator shall conduct the performance
test according to the procedures in subpart A of this part and in this
section.
(b) In conducting performance tests, each owner or operator of an
affected source shall use as reference methods and procedures the test
methods in 40 CFR part 60, appendix A, or other methods and procedures
as specified in this section, except as provided in Sec. 63.7(f).
(c) Each owner or operator of a new or existing diammonium and/or
monoammonium phosphate process line or granular triple superphosphate
process line shall determine compliance with the applicable total
fluorides standards in Sec. 63.622 or Sec. 63.623 as follows:
(1) The emission rate (E) of total fluorides shall be computed for
each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR10JN99.001
Where:
E = emission rate of total fluorides, g/metric ton (lb/ton) of
equivalent P2O5 feed.
Csi = concentration of total fluorides from emission point
``i,'' mg/dscm (mg/dscf).
Qsdi = volumetric flow rate of effluent gas from emission
point ``i,'' dscm/hr (dscf/hr).
N = number of emission points associated with the affected facility.
P = equivalent P2O5 feed rate, metric ton/hr (ton/
hr).
K = conversion factor, 1000 mg/g (453,600 mg/lb).
(2) Method 13A or 13B (40 CFR part 60, appendix A) shall be used to
determine the total fluorides concentration (Csi) and
volumetric flow rate (Qsdi) of the effluent gas from each of
the emission points. If Method 13 B is used, the fusion of the filtered
material described in section 7.3.1.2 and the distillation of suitable
aliquots of containers 1 and 2, described in sections 7.3.3 and 7.3.4 in
Method 13 A, may be omitted. The sampling time and sample volume for
each run shall be at least one hour and 0.85 dscm (30 dscf).
(3) The equivalent P2O5 feed rate (P) shall be
computed using the following equation:
P = Mp Rp
Where:
Mp = total mass flow rate of phosphorus-bearing feed, metric
ton/hr (ton/hr).
Rp = P2O5 content, decimal fraction.
(i) The accountability system described in Sec. 63.625(a) and (b)
shall be used to determine the mass flow rate (Mp) of the
phosphorus-bearing feed.
(ii) The P2O5 content (Rp) of the
feed shall be determined using as appropriate the following methods
(incorporated by reference--see 40 CFR 63.14) specified in the Book of

material described in section 7.3.1.2 and the distillation of suitable
aliquots of containers 1 and 2, described in Sections 7.3.3 and 7.3.4 in
Method 13 A, may be omitted. The sampling time and sample volume for
each run shall be at least one hour and 0.85 dscm (30 dscf).
(iii) The equivalent P2O5 feed rate (P) shall
be computed using the following equation:
P = Mp Rp
Where:
Mp = amount of product in storage, metric ton (ton).
Rp = P2O5 content of product in
storage, weight fraction.
(iv) The accountability system described in Sec. 63.625(d) and (e)
shall be used to determine the amount of product (Mp) in
storage.
(v) The P2O5 content (Rp) of the
product stored shall be determined using as appropriate the following
methods (incorporated by reference--see 40 CFR 63.14) specified in the

hours during the calendar year;
(4) Catalytic cracking unit and catalytic reformer catalyst
regeneration vents, and sulfur plant vents; and
(5) Emission points routed to a fuel gas system, as defined in
Sec. 63.641 of this subpart. No testing, monitoring, recordkeeping, or
reporting is required for refinery fuel gas systems or emission points
routed to refinery fuel gas systems.
(e) The owner or operator shall follow the procedures specified in
paragraphs (e)(1) and (e)(2) of this section to determine whether a
storage vessel is part of a source to which this subpart applies.
(1) Where a storage vessel is used exclusively by a process unit,
the storage vessel shall be considered part of that process unit.
(i) If the process unit is a petroleum refining process unit subject
to this subpart, then the storage vessel is part of the affected source
to which this subpart applies.
(ii) If the process unit is not subject to this subpart, then the
storage vessel is not part of the affected source to which this subpart
applies.
(2) If a storage vessel is not dedicated to a single process unit,
then the applicability of this subpart shall be determined according to
the provisions in paragraphs (e)(2)(i) through (e)(2)(iii) of this
section.
(i) If a storage vessel is shared among process units and one of the
process units has the predominant use, as determined by paragraphs
(e)(2)(i)(A) and (e)(2)(i)(B) of this section, then the
[[Page 30]]
storage vessel is part of that process unit.
(A) If the greatest input on a volume basis into the storage vessel
is from a process unit that is located on the same plant site, then that
process unit has the predominant use.
(B) If the greatest input on a volume basis into the storage vessel
is provided from a process unit that is not located on the same plant
site, then the predominant use shall be the process unit that receives
the greatest amount of material on a volume basis from the storage
vessel at the same plant site.
(ii) If a storage vessel is shared among process units so that there
is no single predominant use, and at least one of those process units is
a petroleum refining process unit subject to this subpart, the storage
vessel shall be considered to be part of the petroleum refining process
unit that is subject to this subpart. If more than one petroleum
refining process unit is subject to this subpart, the owner or operator
may assign the storage vessel to any of the petroleum refining process
units subject to this subpart.
(iii) If the predominant use of a storage vessel varies from year to
year, then the applicability of this subpart shall be determined based
on the utilization of that storage vessel during the year preceding
promulgation of this subpart. This determination shall be reported as
specified in Sec. 63.654(h)(6)(ii) of this subpart.
(f) The owner or operator shall follow the procedures specified in
paragraphs (f)(1) through (f)(5) of this section to determine whether a
miscellaneous process vent from a distillation unit is part of a source
to which this subpart applies.
(1) If the greatest input to the distillation unit is from a process
unit located on the same plant site, then the distillation unit shall be
assigned to that process unit.
(2) If the greatest input to the distillation unit is provided from
a process unit that is not located on the same plant site, then the
distillation unit shall be assigned to the process unit located at the
same plant site that receives the greatest amount of material from the
distillation unit.
(3) If a distillation unit is shared among process units so that
there is no single predominant use, as described in paragraphs (f)(1)
and (f)(2) of this section, and at least one of those process units is a
petroleum refining process unit subject to this subpart, the
distillation unit shall be assigned to the petroleum refining process
unit that is subject to this subpart. If more than one petroleum
refining process unit is subject to this subpart, the owner or operator
may assign the distillation unit to any of the petroleum refining
process units subject to this rule.
(4) If the process unit to which the distillation unit is assigned
is a petroleum refining process unit subject to this subpart and the
vent stream contains greater than 20 parts per million by volume total
organic hazardous air pollutants, then the vent from the distillation
unit is considered a miscellaneous process vent (as defined in
Sec. 63.641 of this subpart) and is part of the source to which this
subpart applies.
(5) If the predominant use of a distillation unit varies from year
to year, then the applicability of this subpart shall be determined
based on the utilization of that distillation unit during the year
preceding promulgation of this subpart. This determination shall be
reported as specified in Sec. 63.654(h)(6)(iii).

following procedures shall be used to calculate parts per million by
volume concentration:
(i) The minimum sampling time for each run shall be 1 hour in which
either an integrated sample or four grab samples shall be taken. If grab
sampling is used, then the samples shall be taken at approximately equal

basis unless a permit change is made.
(4) The owner or operator shall decide no later than the first
monitoring period after the phase III compliance date specified in
Sec. 63.640(h) whether to monitor connectors according to the provisions
in Sec. 63.649, paragraphs (b), (c), or (d).
(5) Connectors in gas/vapor service or light liquid service are
subject to the requirements for connectors in heavy liquid service in

[60 FR 43260, Aug. 18, 1995, as amended at 61 FR 29880, June 12, 1996]
Sec. 63.652 Emissions averaging provisions.
(a) This section applies to owners or operators of existing sources
who seek to comply with the emission standard in Sec. 63.642(g) by using
emissions averaging according to Sec. 63.642(l) rather than following
the provisions of Secs. 63.643 through 63.647, and Secs. 63.650 and
63.651. Existing marine tank vessel loading operations unable to comply
with the standard by using emissions averaging are those marine tank
vessels subject to 40 CFR 63.562(e) of this part and the Valdez Marine
Terminal source.
(b) The owner or operator shall develop and submit for approval an
Implementation Plan containing all of the information required in
Sec. 63.653(d) for all points to be included in an emissions average.
The Implementation Plan shall identify all emission points to be
included in the emissions average. This must include any Group 1
emission points to which the reference control technology (defined in
Sec. 63.641) is not applied and all other emission points being
controlled as part of the average.
(c) The following emission points can 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:
(1) Group 2 emission points;
(2) Group 1 storage vessels, Group 1 wastewater streams, Group 1
gasoline loading racks, Group 1 marine tank vessels, and Group 1
miscellaneous process vents 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 must be submitted and
approved as provided in paragraph (i) of this section; and
(3) Emission points from which emissions are reduced by pollution
prevention measures. Percentages of reduction for pollution prevention
measures shall be determined as specified in paragraph (j) of this
section.
(i) For a Group 1 emission point, the pollution prevention measure
must reduce emissions more than the reference control technology would
have had the reference control technology been applied to the emission
point instead of the pollution prevention measure except as provided in
paragraph (c)(3)(ii) of this section.
(ii) If a pollution prevention measure is used in conjunction with
other controls for a Group 1 emission point, the pollution prevention
measure alone does not have to reduce emissions more than the reference
control technology, but the combination of the pollution prevention
measure and other controls must reduce emissions more than the reference
control technology would have had it been applied instead.
(d) The following emission points cannot be used to generate
emissions averaging credits:
(1) Emission points already controlled on or before November 15,
1990 unless the level of control is increased after November 15, 1990,
in which case credit will be allowed only for the increase in control
after November 15, 1990;
[[Page 54]]
(2) Group 1 emission points that are controlled by a reference
control technology 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. For example, it is not allowable to claim that an internal
floating roof meeting only the specifications stated in the reference
control technology definition in Sec. 63.641 (i.e., that meets the
specifications of Sec. 63.119(b) of subpart G but does not have
controlled fittings per Sec. 63.119 (b)(5) and (b)(6) of subpart G)
applied to a storage vessel is achieving greater than 95 percent
control;
(3) Emission points on shutdown process units. Process units that
are shut down cannot be used to generate credits or debits;
(4) Wastewater that is not process wastewater or wastewater streams
treated in biological treatment units. These two types of wastewater
cannot be used to generate credits or debits. Group 1 wastewater streams
cannot be left undercontrolled or uncontrolled to generate debits. For
the purposes of this section, the terms ``wastewater'' and ``wastewater
stream'' are used to mean process wastewater; and
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart, 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.
(e) For all points included in an emissions average, the owner or
operator shall:
(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 for those emission points. Equations in paragraph (g)
of this section shall be used to calculate debits.
(2) Calculate and record monthly credits for all Group 1 or Group 2
emission points that are overcontrolled 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 initial demonstration in the Implementation Plan that
credit-generating emission points will be capable of generating
sufficient credits to offset the debits from the debit-generating
emission points must be made under representative operating conditions.
(ii) 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. 63.654(g)(8). Every fourth
Periodic Report shall include a certification of compliance with the
emissions averaging provisions as required by Sec. 63.654(g)(8)(iii).
(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 from the
following:
(1) More than 20 individual emission points. Where pollution
prevention
[[Page 55]]
measures (as specified in paragraph (j)(1) of this section) are used to
control emission points to be included in an emissions average, no more
than 25 emission points may be included in the average. For example, if
two emission points to be included in an emissions average are
controlled by pollution prevention measures, the average may include up
to 22 emission points.
(2) Periods of startup, shutdown, and malfunction as described in
the source's startup, shutdown, and malfunction plan required by
Sec. 63.6(e)(3) of subpart A of this part.
(3) For emission points for which continuous monitors are used,
periods of excess emissions as defined in Sec. 63.654(g)(6)(i). For
these periods, the calculation of monthly credits and debits shall be
adjusted as specified in paragraphs (f)(3)(i) through (f)(3)(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 use the procedures in paragraph (l)
of this section to demonstrate to the Administrator that full or partial
credits or debits should be assigned.
(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 reference control
technology, and the emissions allowed for Group 1 emission point. Debits
shall be calculated as follows:
(1) The overall equation for calculating sourcewide debits is:

specific data in addition to the items listed in paragraph (i)(1) of
this section.
(3) The Administrator shall determine within 120 calendar 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 conditional permission to take
emission credits for use of the control technology on requirements that

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

Federal Register notice is not required to establish the nominal
efficiency for the different technology.
(ii) If, in reviewing the submittal, the permitting authority
believes the control technology has broad applicability for use by other
sources, the permitting authority shall submit the information provided
in the application to the Director of the EPA Office of Air Quality

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,
[[Page 69]]
the Administrator or permitting authority shall deny the application.
(j) The following procedures shall be used for calculating the
efficiency (percentage of reduction) of pollution prevention measures:

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 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 can 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 percentage of reduction
used in the equations in paragraphs (g)(2) and (g)(3) of this section
and paragraphs (h)(2) through (h)(4) of this section is the difference
in percentage 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) The following equation shall be used to calculate the
percentage of reduction of a pollution prevention measure for each
emission point.
[GRAPHIC] [TIFF OMITTED] TR18AU95.036
Where:
Percent reduction=Efficiency of pollution prevention measure (percentage
of organic HAP reduction).

July 14, 1994, 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 the
following equation:
[GRAPHIC] [TIFF OMITTED] TR18AU95.038
where n, Q, H, s, Fem, and HAP 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.

and other information used to determine the percentage of reduction
achieved by a pollution prevention measure for each emission point shall
be fully documented.
(iv) The same pollution prevention measure may reduce emissions from
multiple emission points. In such cases, the percentage of reduction in
emissions for each emission point must be calculated.
(v) For the purposes of the equations in paragraphs (h)(2) through
(h)(6) of this section used to calculate credits for emission points
controlled more stringently than the reference control technology, the
nominal efficiency of a pollution prevention measure is equivalent to
the percentage of reduction of the pollution prevention measure. When a
pollution prevention measure is used, the owner or operator of a source
is not required to apply to the Administrator for a nominal efficiency
and is not subject to paragraph (i) of this section.

the emission points proposed to be included in the average will not
result in greater hazard or, at the option of the State or local
permitting authority, greater risk to human health or the environment
than if the emission points were controlled according to the provisions

equivalent or lower hazard or risk to the satisfaction of the State or
local permitting authority shall not be approved. The State or local
permitting authority may require such adjustments to the emissions
averaging plan as are necessary in order to ensure that the 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. 63.643 through 63.647, and Secs. 63.650 and 63.651.

request that the provisions of paragraphs (l)(1) through (l)(4) of this
section be followed instead of the procedures in paragraphs (f)(3)(i)
and (f)(3)(ii) of this section.
(1) The owner or operator shall notify the Administrator of excess
emissions in the Periodic Reports as required in Sec. 63.654(g)(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 for demonstrating compliance that
are acceptable.
(3) The owner or operator shall provide documentation of the period
of excess emissions 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.

Liability Act (CERCLA) authorities, or similar Federal or State
authorities.
(iv) Waste containing HAP that is generated by residential
households (e.g., old paint, home garden pesticides) and subsequently is
collected as a community service by government agencies, businesses, or
other organizations for the purpose of promoting the proper disposal of
this waste.
(v) Waste that is transferred from a chemical manufacturing plant or
other facility for which both of the following conditions apply to the
waste:
(A) The management of the waste at the facility is required either
under part 63 subpart F--National Emission Standards for Organic
Hazardous Air Pollutants from the Synthetic Organic Chemical

(c) Affected sources. (1) Off-site material management units. For
each operation specified in paragraphs (a)(2)(i) through (a)(2)(vi) of
this section that is located at the plant site, the affected source is
the entire group of off-site material management units associated with
the operation. An off-site material management unit is a tank,
container, surface impoundment, oil-water separator, organic-water
separator, or transfer system used to manage off-site material. For the
purpose of implementing the standards under this subpart, a unit that
meets the definition of a tank or container but also is equipped with a
vent that serves as a process vent for any of the processes listed in
paragraphs (c)(2)(i) through (c)(2)(vi) of this section is not an off-
site material management unit but instead is a process vent and is to be
included in the appropriate affected source group under paragraph (c)(2)
of this section. Examples of such a unit may include, but are not
limited to, a distillate receiver vessel, a primary condenser, a bottoms
receiver vessel, a surge control tank, a separator tank, and a hot well.
(2) Process vents. For each operation specified in paragraphs
(a)(2)(i) through (a)(2)(vi) of this section that is located at the
plant site, the affected source is the entire group of process equipment
associated with the process vents for the processes listed in paragraphs
(c)(2)(i) through (c)(2)(vi) of this section.
(i) Distillation process used for the treatment, recycling, or
recovery of
[[Page 93]]
off-site material. Distillation means a process, either batch or
continuous, separating one or more off-site material feed streams into
two or more exit streams having different component concentrations from
those in the feed stream or streams. The separation is achieved by the
redistribution of the components between the liquid and vapor phases as
they approach equilibrium within the distillation unit.
(ii) Fractionation process used for the treatment, recycling, or
recovery of off-site material. Fractionation means a liquid mixture
separation process or method used to separate a mixture of several
volatile components of different boiling points in successive stages,
each stage removing from the mixture some proportion of one of the
components.
(iii) Thin-film evaporation process used for the treatment,
recycling, or recovery of off-site material. Thin-film evaporation means
a liquid mixture separation process or method that uses a heating
surface consisting of a large diameter tube that may be either straight
or tapered, horizontal or vertical. Liquid is spread on the tube wall by
a rotating assembly of blades that maintain a close clearance from the
wall or actually ride on the film of liquid on the wall.
(iv) Solvent extraction process used for the treatment, recycling,
or recovery of off-site material. Solvent extraction means a separation
process or method in which a solid or a solution is contacted with a
liquid solvent (the material and the solvent being relatively insoluble
in each other) to preferentially dissolve and transfer one or more
components into the solvent.
(v) Steam stripping process used for the treatment, recycling, or
recovery of off-site material. Steam stripping means a liquid mixture
separation process or method in which vaporization of the volatile
components of a liquid mixture occurs by the introduction of steam
directly into the process.
(vi) Gas stripping process used for the treatment, recycling, or
recovery of off-site material. Gas stripping means a desorption process
or method used to transfer one or more volatile components from a liquid
mixture into a gas stream either with or without the application of heat
to the liquid. Packed towers, spray towers, and bubble-cap, sieve, or
valve-type plate towers are examples of the process configurations used
for contacting the gas and a liquid.
(3) Equipment leaks. For each operation specified in paragraphs
(a)(2)(i) through (a)(2)(vi) of this section that is located at the
plant site, the affected source is the entire group of equipment
components for which each component meets all of the conditions
specified in paragraphs (c)(3)(i) through (c)(3)(iii) of this section.
If any one of these conditions do not apply to an equipment component,
then that component is not part of the affected source for equipment
leaks.
(i) The equipment component is a pump, compressor, agitator,
pressure relief device, sampling connection system, open-ended valve or
line, valve, connector, or instrumentation system;
(ii) The equipment component contains or contacts off-site material

weight; and
(iii) The equipment component is intended to operate for 300 hours
or more during a calendar year in off-site material service, as defined
in Sec. 63.681 of this subpart.
(d) Facility-wide exemption. The owner or operator of affected
sources subject to this subpart is exempted from the requirements of
Secs. 63.682 through 63.699 of this subpart in situations when the total
annual quantity of the HAP that is contained in the off-site material
received at the plant site is less than 1 megagram per year. For a plant
site to be exempted under the provisions of this paragraph (d), the
owner or operator must meet the requirements in paragraphs (d)(1)
through (d)(3) of this section.
(1) The owner or operator must prepare an initial determination of
the total annual HAP quantity in the off-site material received at the
plant site. This determination is based on the total quantity of the HAP
listed in Table 1 of this subpart as determined at the point-of-delivery
for each off-site material stream.
(2) The owner or operator must prepare a new determination whenever
the
[[Page 94]]
extent of changes to the quantity or composition of the off-site
material received at the plant site could cause the total annual HAP
quantity in the off-site material received at the plant site to exceed
the limit of 1 megagram per year.
(3) The owner or operator must maintain documentation to support the
owner's or operator's determination of the total annual HAP quantity in
the off-site material received at the plant site. This documentation
must include the basis and data used for determining the HAP content of
the off-site material.
(e) Compliance dates. (1) Existing sources. The owner or operator of
an affected source that commenced construction or reconstruction before
October 13, 1994, must achieve compliance with the provisions of this
subpart on or before the date specified in paragraph (e)(1)(i) or

reconstruction before October 13, 1994 and receives off-site material
for the first time before February 1, 2000, the owner or operator of
this affected source must achieve compliance with the provisions of the
subpart on or before February 1, 2000 unless an extension has been
granted by the Administrator as provided in 40 CFR 63.6(i).
(ii) For an affected source that commenced construction or
reconstruction before October 13, 1994, but receives off-site material
for the first time on or after February 1, 2000, the owner or operator
of the affected source must achieve compliance with the provisions of
this subpart upon the first date that the affected source begins to
manage off-site material.
(2) New sources. The owner or operator of an affected source for
which construction or reconstruction commences on or after October 13,
1994, must achieve compliance with the provisions of this subpart on or
before July 1, 1996, or upon initial startup of operations, whichever
date is later as provided in 40 CFR 63.6(b).

prevent or reduce air pollutant emissions to the atmosphere. A cover may
have openings needed for operation, inspection, sampling, maintenance,
and repair of the unit provided that each opening is closed when not in
use (e.g., access hatches, sampling ports). A cover may be a separate
piece of equipment which can be detached and removed from the unit or a
cover may be formed by structural features permanently integrated into
the design of the unit.
Emission point means an individual tank, surface impoundment,
container, oil-water or organic-water separator, transfer system,

Enclosure means a structure that surrounds a tank or container,
captures organic vapors emitted from the tank or container, and vents
the captured vapor through a closed vent system to a control device.
External floating roof means a pontoon-type or double-deck type
cover that rests on the liquid surface in a tank with no fixed roof.
Fixed roof means a cover that is mounted on a unit in a stationary

implemented by 40 CFR parts 260 and 261.
Individual drain system means a stationary system used to convey
wastewater streams or residuals to a waste management unit or to
discharge or disposal. The term includes hard-piping, all drains and
junction boxes, together with their associated sewer lines and other
junction boxes (e.g., manholes, sumps, and lift stations) conveying
wastewater streams or residuals. For the purpose of this subpart, an
individual drain system is not a drain and collection system that is
designed and operated for the sole purpose of collecting rainfall runoff
(e.g., stormwater sewer system) and is segregated from all other
individual drain systems.
Internal floating roof means a cover that rests or floats on the
liquid surface (but not necessarily in complete contact with it inside a
tank that has a fixed roof).
Light-material service means the container is used to manage an off-
site material for which both of the following conditions apply: the
vapor pressure of one or more of the organic constituents in the off-
site material is greater than 0.3 kilopascals (kPa) at 20 deg.C; and
the total concentration of the pure organic constituents having a vapor
pressure greater than 0.3 kPa at 20 deg.C is equal to or greater than
20 percent by weight.
Liquid-mounted seal means a foam- or liquid-filled continuous seal
mounted in contact with the liquid in a unit.
Maximum HAP vapor pressure means the sum of the individual HAP
equilibrium partial pressure exerted by an off-site material at the
temperature equal to either: the local maximum monthly average
temperature as reported by the National Weather Service when the off-
site material is stored or treated at ambient temperature; or
[[Page 96]]
the highest calendar-month average temperature of the off-site material
when the off-site material is stored at temperatures above the ambient
temperature or when the off-site material is stored or treated at
temperatures below the ambient temperature. For the purpose of this
subpart, maximum HAP vapor pressure is determined using the procedures
specified in Sec. 63.694(j) of this subpart.
Metallic shoe seal means a continuous seal that is constructed of
metal sheets which are held vertically against the wall of the tank by
springs, weighted levers, or other mechanisms and is connected to the
floating roof by braces or other means. A flexible coated fabric
(envelope) spans the annular space between the metal sheet and the
floating roof.

and form of the material comprising the stream remain consistent. An
off-site material stream may be delivered, transferred, or otherwise
moved to the plant site in a continuous flow of material (e.g.,
wastewater flowing through a pipeline) or in a series of discrete
batches of material (e.g., a truckload of drums all containing the same
off-site material or multiple bulk truck loads of an off-site material
produced by the same process).
Oil-water separator means a separator as defined for this subpart
that is used to separate oil from water.
Operating parameter value means a minimum or maximum value
established for a control device or treatment process parameter which,
if achieved by itself or in combination with one or more other operating
parameter values, determines that an owner or operator has complied with
an applicable emission limitation or standard.
Organic-water separator means a separator as defined for this
subpart that is used to separate organics from water.
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. A unit or group of units within
a contiguous property that are not under common control (e.g., a
wastewater treatment unit or solvent recovery unit located at the site
but is sold to a different company) is a different plant site.
Point-of-delivery means the point at the boundary or within the
plant site where the owner or operator first accepts custody, takes
possession, or assumes responsibility for the management of an off-site
material stream managed in a waste management operation or recovery
operation specified in Sec. 63.680 (a)(2)(i) through (a)(2)(vi) of this
subpart. The characteristics of an off-site material stream are
determined prior to combining the off-site material stream with other
off-site material streams or with any other materials.
Point-of-treatment means a point after the treated material exits
the treatment process but before the first point downstream of the
treatment process exit where the organic constituents in the treated
material have the potential to volatilize and be released to the
atmosphere. For the purpose of applying this definition to this subpart,
the first point downstream of the treatment process exit is not a
fugitive emission point due to an equipment leak from
[[Page 97]]
any of the following equipment components: pumps, compressors, valves,
connectors, instrumentation systems, or safety devices.
Process heater means an enclosed combustion device that transfers
heat released by burning fuel directly to process streams or to heat
transfer liquids other than water.
Process vent means an open-ended pipe, stack, or duct through which
a gas stream containing HAP is continuously or intermittently discharged
to the atmosphere from any of the processes listed in
Sec. 63.680(c)(2)(i) through (c)(2)(vi) of this section. For the purpose
of this subpart, a process vent is none of the following: a pressure-
relief vent or other vent that is used as a safety device (as defined in
this section); an open-ended line or other vent that is subject to the
equipment leak control requirements under Sec. 63.691 of this subpart;
or a stack or other vent that is used to exhaust combustion products
from a boiler, furnace, process heater, incinerator, or other combustion
device.
Recovery operation means the collection of off-site material
management units, process vents, and equipment components used at a
plant site to manage an off-site material stream from the point-of-
delivery through the point where the material has been recycled,
reprocessed, or re-refined to obtain the intended product or to remove
the physical and chemical impurities of concern.
Safety device means a closure device such as a pressure relief
valve, frangible disc, fusible plug, or any other type of device which
functions to prevent physical damage or permanent deformation to
equipment by venting gases or vapors during unsafe conditions resulting
from an unplanned, accidental, or emergency event. For the purpose 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
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.
Separator means a waste management unit, generally a tank, used to
separate oil or organics from water. A separator consists of not only
the separation unit but also the forebay and other separator basins,
skimmers, weirs, grit chambers, sludge hoppers, and bar screens that are
located directly after the individual drain system and prior to any
additional treatment units such as an air flotation unit clarifier or
biological treatment unit. Examples of a separator include, but are not
limited to, an API separator, parallel-plate interceptor, and
corrugated-plate interceptor with the associated ancillary equipment.
Single-seal system means a floating roof having one continuous seal.
This seal may be vapor-mounted, liquid-mounted, or a metallic shoe seal.
Surface impoundment means a unit that is a natural topographical
depression, man-made excavation, or diked area formed primarily of
earthen materials (although it may be lined with man-made materials),
which is designed to hold an accumulation of liquids. Examples of
surface impoundments include holding, storage, settling, and aeration
pits, ponds, and lagoons.
Tank means a stationary unit that is constructed primarily of
nonearthen materials (such as wood, concrete, steel, fiberglass, or
plastic) which provide structural support and is designed to hold an
accumulation of liquids or other materials.
Transfer system means a stationary system for which the predominant
function is to convey liquids or solid materials from one point to
another point within a waste management operation or recovery operation.
For the purpose of this subpart, the conveyance
[[Page 98]]
of material using a container (as defined for this subpart) or a self-
propelled vehicle (e.g., a front-end loader) is not a transfer system.
Examples of a transfer system include but are not limited to a pipeline,
an individual drain system, a gravity-operated conveyor (such as a
chute), and a mechanically-powered conveyor (such as a belt or screw
conveyor).
Temperature monitoring device means a piece of equipment used to
monitor temperature and having an accuracy of 1 percent of
the temperature being monitored expressed in degrees Celsius ( deg.C)
or 1.2 degrees deg.C, whichever value is greater.
Treatment process means a process in which an off-site material
stream is physically, chemically, thermally, or biologically treated to
destroy, degrade, or remove hazardous air pollutants contained in the
off-site material. A treatment process can be composed of a single unit
(e.g., a steam stripper) or a series of units (e.g., a wastewater
treatment system). A treatment process can be used to treat one or more
off-site material streams at the same time.
Used oil means any oil refined from crude oil or any synthetic oil
that has been used and as a result of such use is contaminated by
physical or chemical impurities. This definition is the same definition
of ``used oil'' in 40 CFR 279.1.
Used solvent means a mixture of aliphatic hydrocarbons or a mixture
of one and two ring aromatic hydrocarbons that has been used as a
solvent and as a result of such use is contaminated by physical or
chemical impurities.
Vapor-mounted seal means a continuous seal that is mounted such that
there is a vapor space between the liquid in the unit and the bottom of
the seal.
Volatile organic hazardous air pollutant concentration or VOHAP
concentration means the fraction by weight of those compounds listed in
Table 1 of this subpart that are in an off-site material as measured
using Method 305 in appendix A of this part and expressed in terms of
parts per million (ppm). As an alternative to using Method 305, an owner
or operator may determine the HAP concentration of an off-site material
using any one of the other test methods specified in
Sec. 63.694(b)(2)(ii) of this subpart. When a test method specified in
Sec. 63.694(b)(2)(ii) of this subpart other than Method 305 is used to
determine the speciated HAP concentration of an off-site material, the
individual compound concentration may be adjusted by the corresponding
fm305 value listed in Table 1 of this subpart to determine a
VOHAP concentration.
Waste means a material generated from industrial, commercial,
mining, or agricultural operations or from community activities that is
discarded, discharged, or is being accumulated, stored, or physically,
chemically, thermally, or biologically treated prior to being discarded
or discharged.
Waste management operation means the collection of off-site material
management units, process vents, and equipment components used at a
plant site to manage an off-site material stream from the point-of-
delivery to the point where the waste exits or is discharged from the
plant site or the waste is placed for on-site disposal in a unit not
subject to this subpart (e.g., a waste incinerator, a land disposal
unit).
Waste stabilization process means any physical or chemical process
used to either reduce the mobility of hazardous constituents in a waste
or eliminate free liquids as determined by Test Method 9095--Paint
Filter Liquids Test in ``Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods,'' EPA Publication No. SW-846, Third Edition,
September 1986, as amended by Update I, November 15, 1992. (As an
alternative, an owner or operator may use any more recent, updated
version of Method 9095 approved by the EPA.) A waste stabilization
process includes mixing the waste with binders or other materials and
curing the resulting waste and binder mixture. Other synonymous terms
used to refer to this process are ``waste fixation'' or ``waste
solidification.'' A waste stabilization process does not include the
adding of absorbent materials to the surface of a waste, without mixing,
agitation, or subsequent curing, to absorb free liquid.

material before placing the material in the off-site material management
unit by treating the material in accordance with the standards specified
in Sec. 63.684 of this subpart.
(iii) The owner or operator determines before placing off-site
material in the off-site material management unit that the average VOHAP
concentration of the off-site material is less than 500 parts per
million by weight (ppmw) at the point-of-delivery. The owner or operator
must perform an initial determination of the average VOHAP concentration
of the off-site material using the procedures specified in
Sec. 63.694(b) of this subpart. This initial determination must be
performed either before the first time any portion of the off-site
material stream is placed in the unit or by the compliance date,
whichever date is later. Thereafter, the owner or operator must review
and update, as necessary, this determination at least once every
calendar year following the date of the initial determination for the
off-site material stream.
(2) An off-site material management unit is exempted from the
requirements in paragraph (b)(1) of this section when the owner or
operator meets one of the exemptions provided in paragraphs (b)(2)(i)
through (b)(2)(iv) of this section as applicable to the unit.
(i) An off-site material management unit is exempted from the
requirements in paragraph (b)(1) of this section if the off-site
material management unit is also subject to another subpart under 40 CFR
part 63 or 40 CFR part 61, and the owner or operator is controlling the
HAP listed in Table 1 of this subpart that are emitted from the unit in
compliance with the provisions specified in the other applicable subpart
under part 61 or part 63.
(ii) At the discretion of the owner or operator, one or a
combination of off-site material management units may be exempted from

vent stream flow rate. This documentation must include identification of
each process vent exempted under this paragraph and the test results
used to determine the process vent stream flow rate.
(iii) A process vent is exempted from the requirements specified in
paragraph (c)(1) of this section if the owner or operator determines
that the process vent stream flow rate is less than 6.0 m\3\/min at
standard conditions (as defined in 40 CFR 63.2) and the total HAP
concentration is less than 20 ppmv. The process vent stream flow rate
and total HAP concentration shall be determined in accordance with the
procedures specified in Sec. 63.694(m) of this subpart. Documentation
must be prepared by the owner or operator and maintained at the plant
site to support the determination of the process vent stream flow rate
and total HAP concentration. This documentation must include
identification of each process vent exempted under this paragraph
(c)(2)(iii) and the test results used to determine the process vent
stream flow rate and total HAP concentration. The owner or operator must
perform a new determination of the process vent stream flow rate and
total HAP concentration when the extent of changes to operation of the

maintain a formal quality assurance program consistent with Method 8270,
and this program must include the following elements related to
measuring the concentrations of volatile compounds:
(1) Documentation of site-specific procedures to minimize the loss
of
[[Page 122]]

would be obtained had the off-site material samples been analyzed using
Method 305. To adjust these data, the measured concentration for each
individual HAP chemical species contained in the off-site material is
multiplied by the appropriate species-specific adjustment factor
(fm305) listed in Table 1 of this subpart.

material stream; species-specific chemical test data for the off-site
material stream from previous testing that are still applicable to the
current off-site material stream; previous test data for other locations

(ii) If test data are used as the basis for knowledge, then the
owner or operator shall document the test method, sampling protocol, and
the means by which sampling variability and analytical variability are
accounted for in the determination of the average VOHAP concentration.
For example, an owner or operator may use HAP concentration test data
for the off-site material stream that are validated in accordance with
Method 301 in 40 CFR part 63, appendix A of this part as the basis for
knowledge of the off-site material.
(iii) An owner or operator using species-specific chemical
concentration test data as the basis for knowledge of the off-site
material may adjust the test data to the corresponding average VOHAP

maintained. A copy of the written sampling plan shall be maintained on-
site in the plant site operating records. An example of an acceptable
sampling plan includes a plan incorporating sample collection and
handling procedures in accordance with the requirements specified in
``Test Methods for Evaluating Solid Waste, Physical/Chemical Methods,''
EPA Publication No. SW-846 or Method 25D in 40 CFR part 60, appendix A.

this subpart.
(3) Calculations. The average VOHAP concentration (C) a mass-
weighted basis shall be calculated by using the results for all samples
analyzed in accordance with paragraph (c)(2) of this section and the
following equation. An owner or operator using a test method that
provides species-specific chemical concentrations may adjust the
measured concentrations to the corresponding concentration values which
would be obtained had the off-site material samples been analyzed using
Method 305. To adjust these data, the measured concentration for each
individual HAP chemical species contained in the off-site material is
multiplied by the appropriate species-specific adjustment factor
(fm305) listed in Table 1 of this subpart.

[[Page 127]]
(i.e., a location where organic vapor leakage could occur) on the cover
and associated closure devices shall be checked. Potential leak
interfaces that are associated with covers and closure devices include,
but are not limited to: the interface of the cover and its foundation
mounting; the periphery of any opening on the cover and its associated
closure device; and the sealing seat interface on a spring-loaded
pressure-relief valve.
(2) The test shall be performed when the unit contains a material
having a total organic concentration representative of the range of
concentrations for the materials expected to be managed in the unit.
During the test, the cover and closure devices shall be secured in the
closed position.
(3) 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 composition of the organic constituents in the material placed
in the unit, not for each individual organic constituent.
(4) The detection 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.
(5) Calibration gases shall be as follows:
(i) Zero air (less than 10 ppmv hydrocarbon in air); and
(ii) A mixture of methane or n-hexane in air at a concentration of
approximately, but less than, 10,000 ppmv.
(6) An owner or operator may choose to adjust or not adjust the
detection instrument readings to account for the background organic
concentration level. If an owner or operator chooses to adjust the
instrument readings for the background level, the background level value
must be determined according to the procedures in Method 21 of 40 CFR
part 60, appendix A.
(7) Each potential leak interface shall be checked by traversing the
instrument probe around the potential leak interface as close to the
interface as possible, as described in Method 21. In the case when the
configuration of the cover or closure device prevents a complete
traverse of the interface, all accessible portions of the interface
shall be sampled. In the case when the configuration of the closure
device prevents any sampling at the interface and the device is equipped
with an enclosed extension or horn (e.g., some pressure relief devices),
the instrument probe inlet shall be placed at approximately the center
of the exhaust area to the atmosphere.
(8) An owner or operator must determine if a potential leak
interface operates with no detectable emissions using the applicable
procedure specified in paragraph (k)(8)(i) or (k)(8)(ii) of this
section.
(i) If an owner or operator chooses not to adjust the detection
instrument readings for the background organic concentration level, then
the maximum organic concentration value measured by the detection
instrument is compared directly to the applicable value for the
potential leak interface as specified in paragraph (k)(9) of this
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 (k)(6) of this
section is compared with the applicable value for the potential leak
interface as specified in paragraph (k)(9) of this section.
(9) A potential leak interface is determined to operate with no
detectable emissions using the applicable criteria specified in
paragraphs (k)(9)(i) and (k)(9)(ii) of this section.
(i) For a potential leak interface other than a seal around a shaft
that passes through a cover opening, the potential leak interface is
determined to operate with no detectable organic emissions if the
organic concentration value determined in paragraph (k)(8) is less than
500 ppmv.
(ii) For a seal around a shaft that passes through a cover opening,
the potential leak interface is determined to operate with no detectable
organic emissions if the organic concentration
[[Page 128]]
value determined in paragraph (k)(8) is less than 10,000 ppmv.

boiler or process heater.
(ii) To determine compliance with an enclosed combustion device
concentration limit, the sampling site shall be located at the outlet of
the device.

CFR part 60, appendix A of this chapter; alternatively, any other method
or data that has been validated according to the applicable procedures
in Method 301 in 40 CFR part 63, appendix A of this part may be used.
The following procedures shall be used to calculate percent reduction
efficiency:
(i) The minimum sampling time for each run shall be 1 hour in which
either an integrated sample or a minimum of four grab samples shall be
taken. If grab sampling is used, then the samples shall be taken at

(D) The owner shall determine the total surface area of gaps in the
primary seal and in the secondary seal individually using the following
procedure.
(1) The seal gap measurements shall be performed at one or more
floating roof levels when the roof is floating off the roof supports.
(2) Seal gaps, if any, shall be measured around the entire perimeter
of the floating roof in each place where a 0.32-centimeter (cm) (\1/8\-

areas determined for each identified gap location for the primary seal
and the secondary seal individually, and then dividing the sum for each
seal type by the nominal diameter of the tank. These total gap areas for
the primary seal and secondary seal are then compared to the respective
standards for the seal type as specified in Sec. 63.685(f)(1) of this
subpart.

owner or operator shall prepare and maintain documentation describing
the defect, explaining why alternative storage capacity is not
available, and specify a schedule of actions that will ensure that the
control equipment will be repaired or the tank emptied as soon as
possible.
(ii) When a defect is detected during an inspection of a tank that
has been emptied and degassed, the owner or operator shall repair the
defect before refilling the tank.
(c) Owners and operators that use a closed-vent system in accordance
with the provisions of Sec. 63.693 of this subpart shall meet the
following inspection and monitoring requirements:
(1) Each closed-vent system that is used to comply with
Sec. 63.693(c)(1)(i) of this subpart shall be inspected and monitored in
accordance with the following requirements:
(i) At initial startup, the owner or operator shall monitor the
closed-vent system components and connections using the procedures
specified in Sec. 63.694(k) of this subpart to demonstrate that the
closed-vent system operates with no detectable organic emissions.
(ii) After initial startup, the owner or operator shall inspect and
monitor the closed-vent system as follows:
[[Page 133]]
(A) Closed-vent system joints, seams, or other connections that are
permanently or semi-permanently sealed (e.g., a welded joint between two
sections of hard piping or a bolted and gasketed ducting flange) shall
be visually inspected at least once per year to check for defects that
could result in air emissions. The owner or operator shall monitor a
component or connection using the procedures specified in Sec. 63.694(k)
of this subpart to demonstrate that it operates with no detectable
organic emissions following any time the component is repaired or
replaced (e.g., a section of damaged hard piping is replaced with new
hard piping) or the connection is unsealed (e.g., a flange is unbolted).
(B) Closed-vent system components or connections other than those
specified in paragraph (c)(1)(ii)(A) of this section, shall be monitored
at least once per year using the procedures specified in Sec. 63.694(k)
of this subpart to demonstrate that components or connections operate
with no detectable organic emissions.
(iii) In the event that a defect or leak is detected, the owner or
operator shall repair the defect or leak in accordance with the
requirements of paragraph (c)(3) of this section.
(iv) The owner or operator shall maintain a record of the inspection
and monitoring in accordance with the requirements specified in
Sec. 63.696 of this subpart.
(2) Each closed-vent system that is used to comply with
Sec. 63.693(c)(1)(ii) of this subpart shall be inspected and monitored
in accordance with the following requirements:
(i) The closed-vent system shall be visually inspected by the owner
or operator to check for defects that could result in air emissions.
Defects include, but are not limited to, visible cracks, holes, or gaps
in ductwork or piping; loose connections; or broken or missing caps or
other closure devices.
(ii) The owner or operator must perform an initial inspection
following installation of the closed-vent system. Thereafter, the owner
or operator must perform the inspections at least once every calendar
year except as provided for in paragraph (f) of this section.
(iii) In the event that a defect is detected, the owner or operator
shall repair the defect in accordance with the requirements of paragraph
(c)(3) of this section.
(iv) The owner or operator shall maintain a record of the inspection
in accordance with the requirements specified in Sec. 63.696 of this
subpart.
(3) The owner or operator shall repair all detected defects as
follows:
(i) The owner or operator shall make first efforts at repair of the
defect no later than 5 calendar days after detection and repair shall be
completed as soon as possible but no later than 45 calendar days after
detection.
(ii) Repair of a defect may be delayed beyond 45 calendar days if
either of the conditions specified in paragraph (c)(3)(ii)(A) or
(c)(3)(ii)(B) occurs. In this case, the owner or operator must repair
the defect the next time the process or unit that vents to the closed-
vent system is shutdown. Repair of the defect must be completed before
the process or unit resumes operation.
(A) Completion of the repair is technically infeasible without the
shutdown of the process or unit that vents to the closed-vent system.
(B) The owner or operator determines that the air emissions
resulting from the repair of the defect within the specified period
would be greater than the fugitive emissions likely to result by
delaying the repair until the next time the process or unit that vents

(iii) The owner or operator shall maintain a record of the defect
repair in accordance with the requirements specified in Sec. 63.696 of
this subpart.
(d) Owners and operators that use a transfer system equipped with a
cover in accordance with the provisions of Sec. 63.689(c)(1) of this
subpart shall meet the following inspection requirements:
(1) The cover and its closure devices shall be visually inspected by
the owner or operator to check for defects that could result in air
emissions. Defects include, but are not limited to, visible cracks,
holes, or gaps in the cover sections or between the cover and its
mounting; broken, cracked, or otherwise damaged seals or gaskets on
closure devices; and broken or missing hatches, access covers, caps, or
other
[[Page 134]]
closure devices. In the case when a transfer system is buried partially
or entirely underground, inspection is required only for those portions
of the cover that extend to or above the ground surface, and those
connections that are on such portions of the cover (e.g., access
hatches, etc.) and can be opened to the atmosphere.
(2) The owner or operator must perform an initial inspection
following installation of the cover. Thereafter, the owner or operator
must perform the inspections at least once every calendar year except as
provided for in paragraph (f) of this section.
(3) In the event that a defect is detected, the owner or operator
shall repair the defect in accordance with the requirements of paragraph
(d)(5) of this section.
(4) The owner or operator shall maintain a record of the inspection
in accordance with the requirements specified in Sec. 63.696 of this
subpart.
(5) The owner or operator shall repair all detected defects as
follows:
(i) The owner or operator shall make first efforts at repair of the
defect no later than 5 calendar days after detection and repair shall be
completed as soon as possible but no later than 45 calendar days after
detection except as provided in paragraph (d)(5)(ii) of this section.
(ii) Repair of a defect may be delayed beyond 45 calendar days if
the owner or operator determines that repair of the defect requires
emptying or temporary removal from service of the transfer system and no
alternative transfer system is available at the site to accept the
material normally handled by the system. In this case, the owner or
operator shall repair the defect the next time the process or unit that
is generating the material handled by the transfer system stops
operation. Repair of the defect must be completed before the process or
unit resumes operation.
(iii) The owner or operator shall maintain a record of the defect
repair in accordance with the requirements specified in Sec. 63.696 of
this subpart.
(e) Control device monitoring requirements. For each control device
required under Sec. 63.693 of this subpart to be monitored in accordance
with the provisions of this paragraph (e), the owner or operator must
ensure that each control device operates properly by monitoring the
control device in accordance with the requirements specified in
paragraphs (e)(1) through (e)(7) of this section.
(1) A continuous parameter monitoring system must be used to measure
the operating parameter or parameters specified for the control device
in Sec. 63.693(d) through Sec. 63.693(g) of this subpart as applicable
to the type and design of the control device. The continuous parameter
monitoring system must meet the following specifications and
requirements:
(i) The continuous parameter monitoring system must measure either
an instantaneous value at least once every 15 minutes or an average
value for intervals of 15 minutes or less and continuously record
either:
(A) Each measured data value; or
(B) Each block average value for each 1-hour period 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.
(ii) The monitoring system must be installed, calibrated, operated,
and maintained in accordance with the manufacturer's specifications or
other written procedures that provide reasonable assurance that the
monitoring equipment is operating properly.
(2) Using the data recorded by the monitoring system, the owner or
operator must calculate the daily average value for each monitored
operating parameter for each operating day. If operation of the control
device is continuous, the operating day is a 24-hour period. If control
device operation is not continuous, the operating day is the total
number of hours of control device operation per 24-hour period. Valid
data points must be available for 75 percent of the operating hours in
an operating day to compute the daily average.
(3) For each monitored operating parameter, the owner or operator
must establish a minimum operating parameter value or a maximum
operating parameter value, as appropriate, to define
[[Page 135]]
the range of conditions at which the control device must be operated to
continuously achieve the applicable performance requirements specified
in Sec. 63.693(b)(2) of this subpart. Each minimum or maximum operating
parameter value must be established in accordance with the requirements
in paragraphs (e)(3)(i) and (e)(3)(ii) of this section.
(i) If the owner or operator conducts a performance test to
demonstrate control device performance, then the minimum or maximum
operating parameter value must be established based on values measured
during the performance test and supplemented, as necessary, by the
control device design specifications, manufacturer recommendations, or
other applicable information.
(ii) If the owner or operator uses a control device design analysis
to demonstrate control device performance, then the minimum or maximum
operating parameter value must be established based on the control
device design analysis and supplemented, as necessary, by the control
device manufacturer recommendations or other applicable information.
(4) 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 (e)(4)(i) through
(e)(4)(iii) of this section being met. When multiple operating
parameters are monitored for the same control device and during the same
operating day more than one of these operating parameters meets an
excursion criterion specified in paragraphs (e)(4)(i) through
(e)(4)(iii) 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 (e)(3) of this section.
(ii) An excursion occurs when the period of control device operation
is 4 hours or greater in an operating day and the monitoring data are
insufficient to constitute a valid hour of data for at least 75 percent
of the operating hours. Monitoring data are insufficient to constitute a
valid hour of data if measured values are unavailable for any of the 15-
minute periods within the hour.
(iii) An excursion occurs when the period of control device
operation is less than 4 hours in an operating day and more than 1 of
the hours during the period does not constitute a valid hour of data due
to insufficient monitoring data. Monitoring data are insufficient to
constitute a valid hour of data if measured values are unavailable for
any of the 15-minute periods within the hour.
(5) For each excursion, except as provided for in paragraph(e)(6) 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.
(6) An excursion is not a violation of this standard under any one
of the conditions specified in paragraphs (e)(6)(i) and (e)(6)(ii) of
this section.
(i) An excursion is not a violation nor does it count toward the
number of excused excursions allowed under paragraph (e)(6)(ii) of this
section when the excursion occurs during any one of the following
periods:
(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, 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 semiannual report
submitted by the owner or operator in accordance with Sec. 63.697(b)(4)
of this subpart.
(7) Nothing in paragraphs (e)(1) through (e)(6) of this section
shall be
[[Page 136]]
construed to allow or excuse a monitoring parameter excursion caused by
any activity that violates other applicable provisions of this subpart.
(f) Alternative inspection and monitoring interval. Following the
initial inspection and monitoring of a piece of air pollution control
equipment in accordance with the applicable provisions of this section,
subsequent inspection and monitoring of the equipment may be performed
at intervals longer than 1 year when an owner or operator determines
that performing the required inspection or monitoring procedures would
expose a worker to dangerous, hazardous, or otherwise unsafe conditions
and the owner or operator complies with the requirements specified in
paragraphs (f)(1) and (f)(2) of this section.
(1) The owner or operator must prepare and maintain at the plant
site written documentation identifying the specific air pollution
control equipment designated as ``unsafe to inspect and monitor.'' The
documentation must include for each piece of air pollution control
equipment designated as such a written explanation of the reasons why
the equipment is unsafe to inspect or monitor using the applicable
procedures under this section.
(2) The owner or operator must develop and implement a written plan
and schedule to inspect and monitor the air pollution control equipment
using the applicable procedures specified in this section during times
when a worker can safely access the air pollution control equipment. The
required inspections and monitoring must be performed as frequently as
practicable but do not need to be performed more frequently than the
periodic schedule that would be otherwise applicable to the air
pollution control equipment under the provisions of this section. A copy
of the written plan and schedule must be maintained at the plant site.

Subpart EE--National Emission Standards for Magnetic Tape Manufacturing
Operations
Source: 59 FR 64596, Dec. 15, 1994, unless otherwise noted.
Sec. 63.701 Applicability.
(a) Except as specified in paragraph (b) of this section, the
provisions of this subpart apply to:
(1) Each new and existing magnetic tape manufacturing operation
located at a major source of hazardous air pollutant (HAP) emissions;
and
(2) A magnetic tape manufacturing operation for which the owner or
operator chooses to use the provisions of Sec. 63.703(b) and (h) to
obtain a Federally enforceable limit on its potential to emit HAP.
Explanatory Note: A reason the owner or operator would make the
choice described in paragraph (a)(2) of this section is if the plant
site, without this limit, would be a major source. The owner or operator
could use this limit, which would establish the potential to emit from
magnetic tape manufacturing operations, in conjunction with the
potential to emit from the other HAP emission points at the stationary
source, to be an area source. Note, however, that an owner or operator
is not required to use the provisions in Sec. 63.703(b) and (h) to
determine the potential to emit HAP from magnetic tape manufacturing
operations.
(b) This subpart does not apply to the following:
(1) Research or laboratory facilities; and
(2) Any coating operation that produces a quantity of magnetic tape
that is 1 percent or less of total production (in terms of total square
footage coated) from that coating operation in any 12-month period.
(c) The affected source subject to this standard is the magnetic
tape manufacturing operation, as defined in Sec. 63.702.
(d) An owner or operator of an existing affected source subject to
the provisions of this subpart shall comply according to the following
schedule:
(1) Within 3 years after the effective date of the standard, if the
owner or operator is required to install a new add-on air pollution
control device to meet the requirements of Sec. 63.703(c) or (g); or
(2) Within 2 years after the effective date of the standard, if a
new add-on air pollution control device is not
[[Page 144]]
needed to comply with Sec. 63.703(c) or (g) of these standards.
(e) The compliance date for an owner or operator of a new affected
source subject to the provisions of this subpart is immediately upon
startup of the affected source.
(f) The provisions of this subpart apply during periods of startup
and shutdown, and whenever magnetic tape manufacturing operations are
taking place.
(g) Owners or operators of affected sources subject to the
provisions of this subpart shall also comply with the requirements of
subpart A as identified in Table 1, according to the applicability of
subpart A to such sources.
(h) In any title V permit for an affected source, all research or
laboratory facilities that are exempt from the requirements of this
subpart shall be clearly identified.
Sec. 63.702 Definitions.
(a) All terms used in this subpart that are not defined below have
the meaning given to them in the Clean Air Act and in subpart A of this
part.
Add-on air pollution control device means equipment installed at the
end of a process vent exhaust stack or stacks that reduces the quantity
of a pollutant that is emitted to the air. The device may destroy or
secure the pollutant for subsequent recovery. Examples are incinerators,
condensers, carbon adsorbers, and biofiltration units. Transfer
equipment and ductwork are not considered in and of themselves add-on
air pollution control devices.
Bag slitter means a device for enclosed transfer of particulates. A
bag of raw materials is placed in a hopper, the hopper is closed, and an
internal mechanism slits the bag, releasing the particulates into either
a closed conveyor that feeds the mix preparation equipment or into the
mix preparation equipment itself.
Base substrate means the surface, such as plastic or paper, to which
a coating is applied.
Capture efficiency means the fraction of all organic vapors or other
pollutants generated by a process that are directed to an add-on air
pollution control device.
Capture device means a hood, enclosed room, or other means of
collecting HAP vapors or other pollutants into a duct that exhausts to
an add-on air pollution control device.
Carbon adsorber vessel means one vessel in a series of vessels in a
carbon adsorption system that contains carbon and is used to remove
gaseous pollutants from a gaseous emission source.
Car seal means a seal that is placed on a device that is used either
to open a closed valve or close an opened valve so that the position of
the valve cannot be changed without breaking the seal.
Closed system for flushing fixed lines means a system in which the
line to be flushed is disconnected from its original position and
connected to two closed containers, one that contains cleaning solvent
and one that is empty. Solvent is flushed from the container with
cleaning solvent, through the line, and into the empty containers.
Coater or coating applicator means the apparatus used to apply a
coating to a continuous base substrate.
Coating application means the process by which the coating mix is
applied to the base substrate.
Coating operation means any coater, flashoff area, and drying oven
located between a base substrate unwind station and a base substrate
rewind station that coats a continuous base substrate.
Control device efficiency means the ratio of the emissions collected
or destroyed by an add-on air pollution control device to the total
emissions that are introduced to the control device, expressed as a
percentage.
Day means a 24-consecutive-hour period.
Drying oven means a chamber that uses heat to bake, cure,
polymerize, or dry a surface coating; if the coating contains volatile
solvents, the volatile portion is evaporated in the oven.
Enclosed transfer method means a particulate HAP transfer method
that uses an enclosed system to prevent particulate HAP from entering
the atmosphere as dust. Equipment used for this purpose may include
vacuum injection systems or other mechanical transfer systems, bag
slitters, or supersacks.
[[Page 145]]
Equivalent diameter means four times the area of an opening divided
by its perimeter.
Facility means all contiguous or adjoining property that is under
common ownership or control in which magnetic tape manufacturing is
performed. The definition includes properties that are separated only by
a road or other public right-of-way.
Flashoff area means the portion of a coating operation between the
coater and the drying oven where solvent begins to evaporate from the
coated base substrate.
Flushing of fixed lines means the flushing of solvent through lines
that are typically fixed and are not associated with the cleaning of a
tank, such as the line from the mix room to the coater.
Freeboard ratio means the vertical distance from the surface of the
liquid to the top of the sink or tank (freeboard height) divided by the
smaller of the length or width of the sink or tank evaporative area.
Magnetic coatings means coatings applied to base substrates to make
magnetic tape. Components of magnetic coatings may include: Magnetic
particles, binders, dispersants, conductive pigments, lubricants,
solvents, and other additives.
Magnetic particles means particles in the coating mix that have
magnetic properties. Examples of magnetic particles used in magnetic
tape manufacturing are: y-oxide, doped iron oxides, chromium dioxide,
barium ferrite, and metallic particles that usually consist of elemental
iron, cobalt, and/or nickel.
Magnetic tape means any flexible base substrate that is covered on
one or both sides with a coating containing magnetic particles and that
is used for audio recording, video recording, or any type of information
storage.
Magnetic tape manufacturing operation means all of the emission
points within a magnetic tape manufacturing facility that are
specifically associated with the manufacture of magnetic tape. These
include, but are not limited to:
(1) Solvent storage tanks;
(2) Mix preparation equipment;
(3) Coating operations;
(4) Waste handling devices;
(5) Particulate transfer operations;
(6) Wash sinks for cleaning removable parts;
(7) Cleaning involving the flushing of fixed lines;
(8) Wastewater treatment systems; and
(9) Condenser vents associated with distillation and stripping
columns in the solvent recovery area, but not including the vent on a
condenser that is used as the add-on air pollution control device.
Mill means the pressurized equipment that uses the dispersing action
of beads, combined with the high shearing forces of the centrifugal
mixing action, to disperse the aggregates of magnetic particles
thoroughly without reducing particle size.
Mix preparation equipment means the vessels, except for mills, used
to prepare the magnetic coating.
Natural draft opening means any opening in a room, building, or
total enclosure that remains open during operation of the facility and
that is not connected to a duct in which a fan is installed. The rate
and direction of the natural draft through such an opening is a
consequence of the difference in pressures on either side of the wall
containing the opening.
Nonregenerative carbon adsorber means a carbon adsorber vessel in
which the spent carbon bed does not undergo carbon regeneration in the
adsorption vessel.
Operating parameter value means a minimum or maximum value
established for a control device or process parameter that, if achieved
by itself or in combination with one or more other operating parameter
values, determines that an owner or operator has complied with an
applicable emission limitation or standard.
Overall HAP control efficiency means the total efficiency of the
control system, determined by the product of the capture efficiency and
the control device efficiency.
Particulate means any material, except uncombined water, that exists
as liquid or solid particles such as dust, smoke, mist, or fumes at
standard conditions (760 millimeters of mercury, 0 degrees celsius).
[[Page 146]]
Particulate HAP transfer means the introduction of a particulate HAP
into other dry ingredients or a liquid solution.
Removable parts cleaning means cleaning of parts that have been
moved from their normal position to a wash tank or sink containing
solvent for the purpose of cleaning.
Research or laboratory facility means any stationary source whose
primary purpose is to conduct research and development to develop new
processes and products, where such source is operated under the close
supervision of technically trained personnel and is not engaged in the
manufacture of products for commercial sale in commerce, except in a de
minimis manner.
Separator means a device in the wastewater treatment system in which
immiscible solvent is physically separated from the water with which it
is mixed.
Solvent storage tanks means the stationary tanks that are associated
with magnetic tape operations and that store virgin solvent, spent
solvent, cleaning solvent, solvent at any stage of the solvent recovery
process, or any volatile compound. They do not serve a process function.
Solvent recovery area means the collection of devices used to remove
HAP emissions from process air, to recover the HAP, and to purify the
HAP. Typically, this area contains a control device such as a carbon
adsorber or condenser, the wastewater treatment system, and the
distillation columns.
Solvent recovery device means, for the purposes of this subpart, an
add-on air pollution control device in which HAP is captured rather than
destroyed. Examples include carbon adsorption systems and condensers.
Supersack means a container of particulate from the manufacturer or
supplier with attached feed tubes and that is used to transfer
particulate under the following conditions: the feed tubes are attached
directly to the mix preparation equipment, the attachment interface is
sealed, and all openings on the mix transfer equipment are closed to the
atmosphere.
Temporary total enclosure means a total enclosure that is
constructed for the sole purpose of measuring the fugitive emissions
from an affected source. A temporary total enclosure must be constructed
and ventilated (through stacks suitable for testing) so that it has
minimal impact on the performance of the permanent capture system. A
temporary total enclosure will be assumed to achieve total capture of
fugitive emissions if it conforms to the requirements found in
Sec. 63.705(c)(4)(i) and if all natural draft openings are at least four
duct or hood equivalent diameters away from each exhaust duct or hood.
Alternatively, the owner or operator may apply to the Administrator for
approval of a temporary enclosure on a case-by-case basis.
Total enclosure means a structure that is constructed around a
gaseous emission source so that all gaseous pollutants emitted from the
source are collected and ducted through a control device, such that 100
percent capture efficiency is achieved. There are no fugitive emissions
from a total enclosure. The only openings in a total enclosure are
forced makeup air and exhaust ducts and any natural draft openings such
as those that allow raw materials to enter and exit the enclosure for
processing. All access doors or windows are closed during routine
operation of the enclosed source. Brief, occasional openings of such
doors or windows to accommodate process equipment adjustments are
acceptable, but if such openings are routine or if an access door
remains open during the entire operation, the access door must be
considered a natural draft opening. The average inward face velocity
across the natural draft openings of the enclosure must be calculated
including the area of such access doors. The drying oven itself may be
part of the total enclosure. A permanent enclosure that meets the
requirements found in Sec. 63.705(c)(4)(i) is a total enclosure.
Utilize means the use of HAP that is delivered to mix preparation
equipment for the purpose of formulating coatings, the use of any other

Sec. 63.705 Performance test methods and procedures to determine initial compliance.
(a) Except as specified in Sec. 63.705(a) (1) through (3), to
determine initial compliance with the emission limits under Sec. 63.703
(c), (d)(2), (e)(1), (f)(1), and (g), the owner or operator shall
conduct an initial performance demonstration as required under Sec. 63.7
using the procedures and test methods listed in Sec. 63.7 and
Sec. 63.705. If multiple emission points are vented to one common
control device to meet the requirements of Sec. 63.703 (c), (d)(2),
(e)(1), and (f)(1), only one performance test is required to demonstrate
initial compliance for that group of emission points. This section also
contains initial compliance demonstration procedures (other than
testing) for owners or operators subject to Sec. 63.703 (c), (d)(1),
(e)(1)(ii), (f)(1)(ii), and (g).
(1) A control device (not enclosure) used to comply with Sec. 63.703
(c), (e), or (f) does not need to be tested if each of the following
criteria are met:
(i) It is used to control gaseous HAP emissions from an existing
affected source;
(ii) It is operating prior to March 11, 1994;
(iii) It is equipped with continuous emission monitors for
determining inlet and outlet total HAP or VOC concentration, such that a
percent efficiency can be calculated; and
[[Page 159]]
(iv) The continuous emission monitors are used to demonstrate
continuous compliance in accordance with Sec. 63.704(c)(3)(i).
(2) The owner or operator is not required to conduct an initial
performance test if the requirements of Sec. 63.7(e)(2)(iv) or
Sec. 63.7(h) are met.
(3) An owner or operator is not required to conduct an initial
performance test for a capture device when:
(i) The room, enclosure, or vent was previously tested to
demonstrate compliance with subpart SSS of part 60; and
(ii) Sufficient data were gathered during the test to establish
operating parameter values in accordance with Sec. 63.704(b)(6) (i),
(ii), and (iii).
(b) When an initial compliance demonstration is required by this
subpart, the procedures in paragraphs (b)(1) through (b)(10) of this
section shall be used in determining initial compliance with the
provisions of this subpart.
(1) EPA Method 24 of appendix A of part 60 is used to determine the
VOC content in coatings. If it is demonstrated to the satisfaction of
the Administrator that plant coating formulation data are equivalent to
EPA Method 24 results, formulation data may be used. In the event of any
inconsistency between an EPA Method 24 test and an affected source's
formulation data, the EPA Method 24 test will govern. For EPA Method 24,
the coating sample must be a 1-liter sample taken into a 1-liter
container at a location and time such that the sample will be
representative of the coating applied to the base substrate (i.e., the
sample shall include any dilution solvent or other VOC added during the
manufacturing process). The container must be tightly sealed immediately
after the sample is taken. Any solvent or other VOC added after the
sample is taken must be measured and accounted for in the calculations
that use EPA Method 24 results.
(2) Formulation data is used to determine the HAP content of
coatings.
(3) Either EPA Method 18 or EPA Method 25A of appendix A of part 60,
as appropriate to the conditions at the site, shall be used to determine
HAP or VOC concentration of air exhaust streams as required by
Sec. 63.705(c). The owner or operator shall submit notice of the
intended test method to the Administrator for approval along with the
notification of the performance test required under Sec. 63.7(b). Method
selection shall be based on consideration of the diversity of organic
species present and their total concentration and on consideration of
the potential presence of interfering gases. Except as indicated in
paragraphs (b)(3) (i) and (ii) of this section, the test shall consist
of three separate runs, each lasting a minimum of 30 minutes.
(i) When either EPA Method 18 or EPA Method 25A is to be used in the
determination of the efficiency of a fixed-bed carbon adsorption system
with a common exhaust stack for all the individual carbon adsorber
vessels pursuant to Sec. 63.705(c) (2) or (4), the test shall consist of
three separate runs, each coinciding with one or more complete sequences
through the adsorption cycles of all of the individual carbon adsorber
vessels.
(ii) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with individual exhaust stacks for each carbon adsorber vessel
pursuant to Sec. 63.705(c) (3) or (4), each carbon adsorber vessel shall
be tested individually. The test for each carbon adsorber vessel shall
consist of three separate runs. Each run shall coincide with one or more
complete adsorption cycles.
(4) EPA Method 1 or 1A of appendix A of part 60 is used for sample
and velocity traverses.
(5) EPA Method 2, 2A, 2C, or 2D of appendix A of part 60 is used for
velocity and volumetric flow rates.
(6) EPA Method 3 of appendix A of part 60 is used for gas analysis.
(7) EPA Method 4 of appendix A of part 60 is used for stack gas
moisture.
(8) EPA Methods 2, 2A, 2C, 2D, 3, and 4 shall be performed, as
applicable, at least twice during each test period.
(9) Wastewater analysis shall be conducted in accordance with
paragraph (b)(9)(i) or (b)(9)(ii) of this section.
[[Page 160]]
(i) Use Method 305 of 40 CFR part 63, appendix A and the equations
in paragraphs (b)(9)(i) (A) and (B) of this section to determine the
total VOHAP concentration of a wastewater stream.
(A) The following equation shall be used to calculate the VOHAP
concentration of an individually speciated HAP.
[GRAPHIC] [TIFF OMITTED] TR15DE94.003
where:
Ci = VOHAP concentration of the individually-speciated
organic HAP in the wastewater, parts per million by weight.
Cc = Concentration of the organic HAP (i) in the gas stream,
as measured by Method 305 of appendix A of this part, parts
per million by volume on a dry basis.
Ms = Mass of sample, from Method 305 of appendix A of this
part, milligrams.
MW = Molecular weight of the organic HAP (i), grams per gram-mole.
24.055 = Ideal gas molar volume at 293 deg. Kelvin and 760 millimeters
of mercury, liters per gram-mole.
Pi = Barometric pressure at the time of sample analysis,
millimeters mercury absolute.
760 = Reference or standard pressure, millimeters mercury absolute.
293 = Reference or standard temperature, deg.Kelvin.
Ti = Sample gas temperature at the time of sample analysis,
deg.Kelvin.
t = Actual purge time, from Method 305 of appendix A of this part,
minutes.
L = Actual purge rate, from Method 305 of appendix A of this part,
liters per minute.
103 = Conversion factor, milligrams per gram.
(B) Total VOHAP concentration (stream) can be determined by summing
the VOHAP concentrations of all individually speciated organic HAP in
the wastewater.
[GRAPHIC] [TIFF OMITTED] TR15DE94.004
where:
Cstream=Total VOHAP concentration of wastewater stream.
n=Number of individual organic HAP (i) in the wastewater stream.
Ci=VOHAP concentration of individual organic HAP (i)
calculated according to the procedures in paragraph
(b)(9)(i)(A) of this section.
(ii) Use a test method or results from a test method that measures
organic HAP concentrations in the wastewater, and that has been
validated according to section 5.1 or 5.3 of Method 301 of appendix A of
this part. The specific requirement of Method 305 of appendix A of this
part to collect the sample into polyethylene glycol would not be
applicable.
(A) If measuring the total VOHAP concentration of the exit stream in
accordance with Secs. 63.703(g)(1)(ii) and 63.705(h)(2), the
concentrations of the individual organic HAP measured in the water shall
be corrected to their concentrations had they been measured by Method
305 of appendix A of this part. This is done by multiplying each
concentration by the compound-specific fraction measured factor

and following the procedures of Sec. 63.705(h)(3), the concentrations of
the individual organic HAP measured in the water do not need to be
corrected.
(10) EPA Method 22 of appendix A of part 60 is used to determine
visible emissions. Visible emissions testing shall be conducted for a
minimum of 6 minutes during a time when particulate HAP transfer, as
defined in this subpart, is occurring.
(c) Initial compliance demonstrations. Except as stipulated in
Sec. 63.705(a), each owner or operator subject to the requirements of
Sec. 63.703(c) must demonstrate initial compliance with the requirements
of this subpart by following the procedures of paragraphs
[[Page 161]]
(c)(1), (2), (3), (4), (5), or (6) and paragraph (d) of this section, as

[GRAPHIC] [TIFF OMITTED] TR15DE94.009
(vi) Determine the efficiency (F) of the capture system using
equation (3).
(vii) For each HAP emission point subject to Sec. 63.703(c),
compliance is demonstrated if the product of (Hsys) x (F) is
equal to or greater than the overall HAP control efficiency required by
Sec. 63.703(c)(1), (c)(3), or (c)(4).
(4) An alternative method of demonstrating compliance with
Sec. 63.703(c)(1) through (c)(4) is the installation of a total
enclosure around the affected HAP emission point(s) and the ventilation
of all HAP emissions from the total enclosure to a control device with
the efficiency or outlet concentration specified in paragraph
(c)(4)(iii) of this section. If this method is selected, the compliance
test methods described in paragraphs (c)(1), (c)(2), and (c)(3) of this
section are not required. Instead,
[[Page 163]]
each owner or operator of an affected source shall:
(i) Demonstrate that a total enclosure is installed. An enclosure
that meets the requirements in paragraphs (c)(4)(i) (A) through (D) of
this section shall be considered a total enclosure. The owner or
operator of an enclosure that does not meet these requirements may apply
to the Administrator for approval of the enclosure as a total enclosure
on a case-by-case basis. The enclosure shall be considered a total
enclosure if it is demonstrated to the satisfaction of the Administrator
that all HAP emissions from the affected HAP emission point(s) are
contained and vented to the control device. The requirements for
automatic approval are as follows:
(A) Total area of all natural draft openings shall not exceed 5
percent of the total surface area of the total enclosure's walls, floor,
and ceiling;
(B) All sources of emissions within the enclosure shall be a minimum
of four equivalent diameters away from each natural draft opening;
(C) Average inward face velocity (FV) across all natural draft
openings shall be a minimum of 3,600 meters per hour as determined by

(1) All forced makeup air ducts and all exhaust ducts are
constructed so that the volumetric flow rate in each can be accurately
determined by the test methods and procedures specified in
Sec. 63.705(b) (4) and (5); volumetric flow rates shall be calculated
without the adjustment normally made for moisture content; and
(2) Determine FV by equation 6:
[GRAPHIC] [TIFF OMITTED] TR15DE94.010
(D) The air passing through all natural draft openings shall flow
into the enclosure continuously. If FV is less than or equal to 9,000
meters per hour, the continuous inward flow of air shall be verified by
continuous observation using smoke tubes, streamers, tracer gases, or
other means approved by the Administrator over the period that the
volumetric flow rate tests required to determine FV are carried out. If
FV is greater than 9,000 meters per hour, the direction of airflow
through the natural draft openings shall be presumed to be inward at all
times without verification.
(ii) Determine the control device efficiency using equation (2) or
equations (4) and (5), as applicable, and the test methods and
procedures specified in Sec. 63.705(b) (3) through (8).

determined from equations (4) and (5), as applicable) is equal to or
greater than the overall HAP control efficiency required by Sec. 63.703
(c)(1), (c)(3), or (c)(4); or
(B) When the owner or operator is subject to Sec. 63.703(c)(2), the
installation of a total enclosure is demonstrated and the value of
Caj at the outlet of the incinerator is demonstrated to be no
greater than 20 ppmv by compound, on a dry basis.

Sec. 63.703(c)(5), each owner or operator of an affected source shall
determine the mass of HAP contained in the coating per volume of coating
solids applied for each batch of coating applied, according to the
procedures of paragraphs (c)(5) (i) through (iii) of this section. If a
batch of coating is identical to a previous batch of coating applied,
the original
[[Page 164]]
calculations can be used to demonstrate the compliance of subsequent
identical batches. The calculation of the HAP content of the coating
used to demonstrate initial compliance with Sec. 63.703(c)(5) shall be
submitted to the Administrator with the notification of compliance
status required by Sec. 63.9(h) and Sec. 63.707(e). When demonstrating
compliance by this procedure, Sec. 63.7(e)(3) of subpart A does not
apply.
(i) Determine the weight fraction of HAP in each coating applied
using formulation data as specified in Sec. 63.705(b)(2);
(ii) Determine the volume of coating solids in each coating applied
from the facility records; and

equation 7:
[GRAPHIC] [TIFF OMITTED] TR15DE94.011
(iv) The owner or operator of an affected source is in compliance
with Sec. 63.703(c)(5) if the value of G is less than or equal to 0.18
kilogram of HAP per liter of coating solids applied.
(6) When nonregenerative carbon adsorbers are used to comply with
Sec. 63.703(c)(1), the owner or operator may conduct a design evaluation
to demonstrate initial compliance in lieu of following the compliance
test procedures of paragraph (c) (1), (2), (3), or (4) of this section.
The design evaluation shall consider the vent stream composition,
constituent concentrations, flow rate, relative humidity, and
temperature, and shall establish the design exhaust vent stream organic
compound concentration level, capacity of the carbon bed, type and
working capacity of activated carbon used for the carbon bed, and design
carbon replacement interval based on the total carbon working capacity
of the control device and the emission point operating schedule.

exiting the treatment process, which are representative of normal flow
and concentration conditions, shall be collected and analyzed.
Wastewater samples shall be collected using the sampling procedures
specified in Method 25D of appendix A of part 60. Where feasible,
samples shall be taken from an enclosed pipe prior to the wastewater

For example, the record may be made by comparing the HAP solvent level
to a permanent mark on the sink that corresponds to a 75 percent
freeboard ratio. A HAP solvent level in the sink higher than the mark
would indicate the minimum ratio has not been achieved.

as a preparatory step to subsequent depainting by non-chemical based
depainting equipment. Softeners may contain VOC
[[Page 176]]
but shall not contain any HAP as determined from MSDS's or manufacturer
supplied information.
Solids means the non-volatile portion of the coating which after
drying makes up the dry film.
Space vehicle means a man-made device, either manned or unmanned,
designed for operation beyond earth's atmosphere. This definition
includes integral equipment such as models, mock-ups, prototypes, molds,
jigs, tooling, hardware jackets, and test coupons. Also included is
auxiliary equipment associated with test, transport, and storage, which
through contamination can compromise the space vehicle performance.
Specialty coating means a coating that, even though it meets the
definition of a primer, topcoat, or self-priming topcoat, has additional
performance criteria beyond those of primers, topcoats, and self-priming
topcoats for specific applications. These performance criteria may
include, but are not limited to, temperature or fire resistance,
substrate compatibility, antireflection, temporary protection or
marking, sealing, adhesively joining substrates, or enhanced corrosion
protection. Individual specialty coatings are defined in appendix A to
this subpart and in the CTG for Aerospace Manufacturing and Rework
Operations (EPA 453/R-97-004).
Spot stripping means the depainting of an area where it is not
technically feasible to use a non-chemical depainting technique.
Spray gun means a device that atomizes a coating or other material
and projects the particulates or other material onto a substrate.
Stripper means a liquid that is applied to an aerospace vehicle or
component to remove permanent coatings such as primers and topcoats.
Surface preparation means the removal of contaminants from the
surface of an aerospace vehicle or component, or the activation or
reactivation of the surface in preparation for the application of a
coating.
Temporary total enclosure means a total enclosure that is
constructed for the sole purpose of measuring the emissions from an
affected source that are not delivered to an emission control device. A
temporary total enclosure must be constructed and ventilated (through
stacks suitable for testing) so that it has minimal impact on the
performance of the permanent emission capture system. A temporary total
enclosure will be assumed to achieve total capture of fugitive emissions
if it conforms to the requirements found in Sec. 63.750(g)(4) and if all
natural draft openings are at least four duct or hood equivalent
diameters away from each exhaust duct or hood. Alternatively, the owner
or operator may apply to the Administrator for approval of a temporary
enclosure on a case-by-case basis.
Topcoat means a coating that is applied over a primer on an
aerospace vehicle or component for appearance, identification,
camouflage, or protection. Coatings that are defined as specialty
coatings are not included under this definition.
Total enclosure means a permanent structure that is constructed
around a gaseous emission source so that all gaseous pollutants emitted
from the source are collected and ducted through a control device, such
that 100% capture efficiency is achieved. There are no fugitive
emissions from a total enclosure. The only openings in a total enclosure
are forced makeup air and exhaust ducts and any natural draft openings
such as those that allow raw materials to enter and exit the enclosure
for processing. All access doors or windows are closed during routine
operation of the enclosed source. Brief, occasional openings of such
doors or windows to accommodate process equipment adjustments are
acceptable, but if such openings are routine or if an access door
remains open during the entire operation, the access door must be
considered a natural draft opening. The average inward face velocity
across the natural draft openings of the enclosure must be calculated
including the area of such access doors. The drying oven itself may be
part of the total enclosure. An enclosure that meets the requirements
found in Sec. 63.750(g)(4) is a permanent total enclosure.
Touch-up and repair operation means that portion of the coating
operation that is the incidental application of
[[Page 177]]
coating used to cover minor imperfections in the coating finish or to
achieve complete coverage. This definition includes out-of-sequence or
out-of-cycle coating.
Two-stage filter system means a dry particulate filter system using
two layers of filter media to remove particulate. The first stage is
designed to remove the bulk of the particulate and a higher efficiency
second stage is designed to remove smaller particulate.
Type I etchant means a chemical milling etchant that contains
varying amounts of dissolved sulfur and does not contain amines.
Type II etchant means a chemical milling etchant that is a strong
sodium hydroxide solution containing amines.
Volatile organic compound (VOC) means any compound defined as VOC in
40 CFR 51.100. This includes any organic compound other than those
determined by the EPA to be an exempt solvent. For purposes of
determining compliance with emission limits, VOC will be measured by the
approved test methods. Where such a method also inadvertently measures
compounds that are exempt solvent, an owner or operator may exclude
these exempt solvents when determining compliance with an emission
standard.
Waterborne (water-reducible) coating means any coating that contains
more than 5 percent water by weight as applied in its volatile fraction.
Waterwash system means a control system that utilizes flowing water
(i.e., a conventional waterwash system) or a pumpless system to remove
particulate emissions from the exhaust air stream in spray coating
application or dry media blast depainting operations.

(B) Uses an alternative application technique, as allowed under
Sec. 63.745(f)(1)(ix), such that the emissions of both organic HAP and

(iv) Operates all application techniques in accordance with the
manufacturer's specifications or locally prepared operating procedures.
(e) Inorganic HAP emissions--primer and topcoat application
operations. For each primer or topcoat application operation that emits
inorganic HAP, the operation is in compliance when:
(1) It is operated according to the requirements specified in
Sec. 63.745(g)(1) through (g)(3); and
(2) It is shut down immediately whenever the pressure drop or water
flow rate is outside the limit(s) established for them and is not
restarted until the pressure drop or water flow rate is returned within
these limit(s), as required under Sec. 63.745(g)(3).
(f) Organic HAP emissions--Depainting operations--(1) Performance
test periods. When using a control device other than a carbon adsorber,
three 1-hour runs constitute the test period for the initial and any
subsequent performance test. When a carbon adsorber is used, each
rolling material balance period is considered a performance test. Each
24-hour period is considered a performance test period for determining
compliance with Sec. 63.746(b)(1). For uncontrolled organic emissions
from depainting operations, each calendar year is considered a
performance test period for determining compliance with the HAP limits
for organic HAP-containing chemical strippers used for spot stripping
and decal removal.
(2) Initial performance tests. If a control device is used, each
owner or operator shall conduct an initial performance test to
demonstrate compliance with the overall reduction efficiency specified
in Sec. 63.746(c), unless a waiver is obtained under either
Sec. 63.7(e)(2)(iv) or Sec. 63.7(h). The initial performance test shall
be conducted according to the procedures and test methods specified in
Sec. 63.7 and Sec. 63.750(g) for carbon adsorbers and in Sec. 63.750(h)
for control devices other than carbon adsorbers. For carbon adsorbers,
the initial performance test shall be used to establish the appropriate
rolling material balance period for determining compliance. The
procedures in paragraphs (2)(i) through (2)(vi) of this section shall be
used in determining initial compliance with the provisions of this
subpart for carbon adsorbers.
(i)(A) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with a common exhaust stack for all the individual carbon
adsorber vessels pursuant to Sec. 63.750(g)(2) or (4), the test shall
consist of three separate runs, each coinciding with one or more
complete sequences through the adsorption cycles of all of the
individual carbon adsorber vessels.
(B) When either EPA Method 18 or EPA Method 25A is to be used in the
determination of the efficiency of a fixed-bed carbon adsorption system
with individual exhaust stacks for each carbon adsorber vessel pursuant
to Sec. 63.750(g) (3) or (4), each carbon adsorber vessel shall be
tested individually. The test for each carbon adsorber vessel shall
consist of three separate runs. Each run shall coincide with one or more
complete adsorption cycles.
(ii) EPA Method 1 or 1A of appendix A of part 60 is used for sample
and velocity traverses.
(iii) EPA Method 2, 2A, 2C, or 2D of appendix A of part 60 is used

applicable, at least twice during each test period.
(3) An organic HAP-containing chemical stripper depainting operation
is considered in compliance when the conditions specified in paragraph
(g)(3)(i) of this section are met.
(i) If a carbon adsorber (or other control device) is used, the
overall control efficiency of the control system, as determined using
the procedures specified in Sec. 63.750(g) (or other control device as
determined using the procedures specified in Sec. 63.750(h)), is equal
to or greater than 81% for control systems installed before the
effective date, or equal to or greater than 95% for control systems
installed on or after the effective date, during the initial performance
test and all subsequent material balances (or performance tests, as
appropriate).
(ii) For non-HAP depainting operations complying with
Sec. 63.746(b)(1);
(A) For any spot stripping and decal removal, the value of C, as
determined using the procedures specified in Sec. 63.750(j), is less
than or equal to 26 gallons of organic HAP-containing chemical stripper
or 190 pounds of organic HAP per commercial aircraft depainted
calculated on a yearly average; and is less than or equal to 50 gallons
of organic HAP-containing chemical stripper or 365 pounds of organic HAP
per military aircraft depainted calculated on a yearly average; and
(B) The requirements of Sec. 63.746(b)(2) are carried out during
malfunctions of non-chemical based equipment.
(g) Inorganic HAP emissions--depainting operations. Each depainting
operation is in compliance when:
(1) The operating requirements specified in Sec. 63.746(b)(4) are
followed; and
(2) It is shut down immediately whenever the pressure drop or water
flow rate is outside the limit(s) established for them and is not
restarted until the pressure drop or water flow rate is returned within
these limit(s), as required under Sec. 63.746(b)(4)(v).
(h) Chemical milling maskant application operations--(1) Performance
test periods. For uncontrolled chemical milling maskants that are not
averaged, each 24-hour period is considered a performance test. For
compliant and noncompliant chemical milling maskants that are averaged
together, each 30-day period is considered a performance test, unless
the permitting agency specifies a shorter period as part of an ambient
ozone control program. When using a control device other than a carbon
adsorber, three 1-hour runs constitute the test period for the initial
and any subsequent performance test. When a carbon adsorber is used,
each rolling material balance period is considered a performance test.
(2) Initial performance tests. If a control device is used, each
owner or operator shall conduct an initial performance test to
demonstrate compliance with the overall reduction efficiency specified
in Sec. 63.747(d), unless a waiver is obtained under either
Sec. 63.7(e)(2)(iv) or Sec. 63.7(h). The initial performance test shall
be conducted according to the procedures and test methods specified in
Sec. 63.7 and Sec. 63.750(g) for carbon adsorbers and in Sec. 63.750(h)
for control devices other than carbon adsorbers. For carbon adsorbers,
the initial performance test shall be used to establish the appropriate
rolling material balance period for determining compliance. The
procedures in paragraphs (h)(2) (i) through (vi) of this section shall
be used in determining initial compliance with the provisions of this
subpart for carbon adsorbers.
(i)(A) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with a common exhaust stack for all the individual carbon

(3) The chemical milling maskant application operation is considered
in compliance when the conditions specified in paragraphs (i)(3)(i) and
(i)(3)(ii) of this section are met.
(i) For all uncontrolled chemical milling maskants, all values of
Hi and Ha (as determined using the procedures
specified in Sec. 63.750 (k) and (l)) are less than or equal to 622
grams of organic HAP per liter (5.2 lb/gal) of Type I chemical milling
maskant as applied (less water), and 160 grams of organic HAP per liter
(1.3 lb/gal) of Type II chemical milling maskant as applied (less
water). All values of Gi and Ga (as determined
using the procedures specified in Sec. 63.750 (m) and (n)) are less than
or equal to 622 grams of VOC per liter (5.2 lb/gal) of Type I chemical
milling maskant as applied (less water and exempt solvents), and 160
grams of VOC per liter (1.3 lb/gal) of Type II chemical milling maskant

Sec. 63.750 Test methods and procedures.
(a) Composition determination. Compliance with the hand-wipe
cleaning solvent approved composition list specified in
Sec. 63.744(b)(1) for hand-wipe cleaning solvents shall be demonstrated
using data supplied by the manufacturer of the cleaning solvent. The
data shall identify all components of the cleaning solvent and shall
demonstrate that one of the approved composition definitions is met.
(b) Vapor pressure determination. The composite vapor pressure of
hand-wipe cleaning solvents used in a cleaning operation subject to this
subpart shall be determined as follows:
(1) For single-component hand-wipe cleaning solvents, the vapor
pressure shall be determined using MSDS or other manufacturer's data,
standard engineering reference texts, or other equivalent methods.
(2) The composite vapor pressure of a blended hand-wipe solvent
shall be determined by quantifying the amount of each organic compound
in the blend using manufacturer's supplied data or a gas chromatographic
analysis in accordance with ASTM E 260-91 or 96 (incorporated by
reference--see Sec. 63.14 of Subpart A of this part) and by calculating
the composite vapor pressure of the solvent by summing the partial
pressures of each component. The vapor pressure of each component shall
be determined using manufacturer's data, standard engineering reference
texts, or other equivalent methods. The following equation shall be used
to determine the composite vapor pressure:
[GRAPHIC] [TIFF OMITTED] TR01SE98.000
where:
Wi=Weight of the ``i''th VOC compound, grams.
Ww=Weight of water, grams.
We=Weight of non-HAP, nonVOC compound, grams.
MWi=Molecular weight of the ``i''th VOC compound, g/g-mole.
MWw=Molecular weight of water, g/g-mole.

[[Page 194]]
PPc=VOC composite partial pressure at 20 deg.C, mm Hg.
VPi=Vapor pressure of the ``i''th VOC compound at 20 deg.C,
mm Hg.
(c) Organic HAP content level determination--compliant primers and
topcoats. For those uncontrolled primers and topcoats complying with the
primer and topcoat organic HAP content limits specified in
Sec. 63.745(c) without being averaged, the following procedures shall be
used to determine the mass of organic HAP emitted per volume of coating
(less water) as applied.
(1) For coatings that contain no exempt solvents, determine the
total organic HAP content using manufacturer's supplied data or Method
24 of 40 CFR part 60, appendix A, to determine the VOC content. The VOC
content shall be used as a surrogate for total HAP content for coatings
that contain no exempt solvent. If there is a discrepancy between the
manufacturer's formulation data and the results of the Method 24
analysis, compliance shall be based on the results from the Method 24
analysis.
When Method 24 is used to determine the VOC content of water-
reducible coatings, the precision adjustment factors in Reference Method
24 shall be used. If the adjusted analytical VOC content is less than
the formulation solvent content, then the analytical VOC content should
be set equal to the formulation solvent content.
(2) For each coating formulation as applied, determine the organic
HAP weight fraction, water weight fraction (if applicable), and density
from manufacturer's data. If these values cannot be determined using the
manufacturer's data, the owner or operator shall submit an alternative
procedure for determining their values for approval by the
Administrator. Recalculation is required only when a change occurs in
the coating formulation.
(3) For each coating as applied, calculate the mass of organic HAP
emitted per volume of coating (lb/gal) less water as applied using
equations 1, 2, and 3:

where:
Hi=mass of organic HAP emitted per volume of coating i (lb/
gal) less water as applied.
MHi=mass (lb) of organic HAP in one gal of coating i.
Vwi=volume (gal) of water in one gal of coating i.
(d) Organic HAP content level determination--averaged primers and
topcoats. For those uncontrolled primers and topcoats that are averaged
together in order to comply with the primer and topcoat organic HAP
content limits specified in Sec. 63.745(c), the following procedure
shall be used to determine the monthly volume-weighted average mass of
organic HAP emitted per volume of coating (less water) as applied,
unless the permitting agency specifies a shorter averaging period as
part of an ambient ozone control program.
(1)(i) Determine the total organic HAP weight fraction as applied of
each coating. If any ingredients, including diluent solvent, are added
to a coating prior to its application, the organic HAP weight fraction
of the coating shall be determined at a time and location in the process
after all ingredients have been added.
(ii) Determine the total organic HAP weight fraction of each coating
as applied each month.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the organic HAP content of the coating, the
[[Page 195]]
value previously determined may continue to be used until a change in
formulation has been made by either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the organic HAP content of the coating, the total
organic HAP weight fraction of the coating shall be redetermined.
(iii) Manufacturer's formulation data may be used to determine the
total organic HAP content of each coating and any ingredients added to
the coating prior to its application. If the total organic HAP content
cannot be determined using the manufacturer's data, the owner or
operator shall submit an alternative procedure for determining the total
organic HAP weight fraction for approval by the Administrator.
(2)(i) Determine the volume both in total gallons as applied and in
total gallons (less water) as applied of each coating. If any
ingredients, including diluent solvents, are added prior to its
application, the volume of each coating shall be determined at a time
and location in the process after all ingredients (including any diluent
solvent) have been added.
(ii) Determine the volume of each coating (less water) as applied
each month, unless the permitting agency specifies a shorter period as
part of an ambient ozone control program.
(iii) The volume applied may be determined from company records.
(3)(i) Determine the density of each coating as applied. If any
ingredients, including diluent solvent, are added to a coating prior to
its application, the density of the coating shall be determined at a
time and location in the process after all ingredients have been added.
(ii) Determine the density of each coating as applied each month,
unless the permitting agency specifies a shorter period as part of an
ambient ozone control program.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the density of the coating, then the value previously determined may
continue to be used until a change in formulation has been made by
either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the density of the coating, then the density of
the coating shall be redetermined.
(iii) The density may be determined from company records, including
manufacturer's data sheets. If the density of the coating cannot be
determined using the company's records, including the manufacturer's
data, then the owner or operator shall submit an alternative procedure
for determining the density for approval by the Administrator.
(4) Calculate the total volume in gallons as applied (less water) by
summing the individual volumes of each coating (less water) as applied,
which were determined under paragraph (d)(2) of this section.
(5) Calculate the volume-weighted average mass of organic HAP in
coatings emitted per unit volume (lb/gal) of coating (less water) as
applied during each 30-day period using equation 4:
[GRAPHIC] [TIFF OMITTED] TR01SE95.007
where:
Ha=volume-weighted average mass of organic HAP emitted per
unit volume of coating (lb/gal) (less water) as applied during
each 30-day period for those coatings being averaged.

For those uncontrolled primers and topcoats complying with the primer
and topcoat VOC content levels specified in Sec. 63.745(c) without being
averaged, the following procedure shall be used to determine the mass of
VOC emitted per volume of coating (less water and exempt solvents) as
applied.
(1) Determine the VOC content of each formulation (less water and
exempt solvents) as applied using manufacturer's supplied data or Method
24 of 40 CFR part 60, appendix A, to determine the VOC content. The VOC
content shall be used as a surrogate for total HAP content for coatings
that contain no exempt solvent. If there is a discrepancy between the
manufacturer's formulation data and the results of the Method 24
analysis, compliance shall be based on the results from the Method 24
analysis.
When Method 24 is used to determine the VOC content of water-
reducible coatings, the precision adjustment factors in Reference Method
24 shall be used. If the adjusted analytical VOC content is less than
the formulation solvent content, then the analytical VOC content should
be set equal to the formulation solvent content.
(2) For each coating applied, calculate the mass of VOC emitted per
volume of coating (lb/gal) (less water and exempt solvents) as applied
using equations 5, 6, and 7:
[GRAPHIC] [TIFF OMITTED] TR01SE95.008
where:
Vwi=volume (gal) of water in one gal of coating i.
Dci=density (lb of coating per gal of coating) of coating i.
Wwi=weight fraction (expressed as a decimal) of water in
coating i.
Dw=density of water, 8.33 lb/gal.

(3)(i) If the VOC content is found to be different when EPA Method
24 is used during an enforcement inspection from that used by the owner
or operator in calculating Ga, compliance shall be based,
except as provided in paragraph (e)(3)(ii) of this section, upon the VOC
content obtained using EPA Method 24.
(ii) If the VOC content of a coating obtained using Method 24 would
indicate noncompliance as determined under either Sec. 63.749 (d)(3)(i)
or (d)(4)(i), an owner or operator may elect to average the coating with
other uncontrolled coatings and (re)calculate Gi (using the
procedure specified in paragraph (f) of this section), provided
appropriate and sufficient records were maintained for all coatings
included in the average (re)calculation. The (re)calculated value of
Gi (Ga in paragraph (f)) for the averaged coatings
shall then be used to determine compliance.
(f) VOC content level determination--averaged primers and topcoats.
For those uncontrolled primers and topcoats that are averaged within
their respective coating category in order to comply with the primer and
topcoat VOC content limits specified in Sec. 63.745 (c)(2) and (c)(4),
the following procedure shall be used to determine the monthly volume-
weighted average mass of VOC emitted per volume of coating (less water
and exempt solvents) as applied, unless the permitting agency specifies
a shorter averaging period as part of an ambient ozone control program.
(1)(i) Determine the VOC content (lb/gal) as applied of each
coating. If any ingredients, including diluent solvent, are added to a
coating prior to its application, the VOC content of the coating shall
be determined at a time and
[[Page 197]]
location in the process after all ingredients have been added.
(ii) Determine the VOC content of each coating as applied each
month, unless the permitting agency specifies a shorter period as part
of an ambient ozone control program.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the VOC content of the coating, the value previously determined may
continue to be used until a change in formulation has been made by
either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the VOC content of the coating, the VOC content
of the coating shall be redetermined.
(iii) Determine the VOC content of each primer and topcoat
formulation (less water and exempt solvents) as applied using EPA Method
24 or from manufacturer's data.
(2)(i) Determine the volume both in total gallons as applied and in
total gallons (less water and exempt solvents) as applied of each

to its application, the volume of each coating shall be determined at a
time and location in the process after all ingredients (including any
diluent solvent) have been added.
(ii) Determine the volume of each coating (less water and exempt
solvents) as applied each day.
(iii) The volume applied may be determined from company records.
(3) Calculate the total volume in gallons (less water and exempt

Vci=volume (gal) of coating i (less water and exempt
solvents) as applied that is being averaged during the 30-day
period.
Clwes=total volume (gal) of all coatings (less water and
exempt solvents) as applied during each 30-day period for
those coatings being averaged.
(5)(i) If the VOC content is found to be different when EPA Method
24 is used during an enforcement inspection from that used by the owner
or operator in calculating Ga, recalculation of Ga
is required using the new value. If more than one coating is involved,
the recalculation shall be made once using all of the new values.
(ii) If recalculation is required, an owner or operator may elect to
include in the recalculation of Ga uncontrolled coatings that
were not previously included provided appropriate and sufficient records
were maintained for these other coatings to allow daily recalculations.
(iii) The recalculated value of Ga under either paragraph
(f)(5)(i) or (f)(5)(ii) of this section shall be used to determine
compliance.
(g) Overall VOC and/or organic HAP control efficiency--carbon

Sec. 63.745(d), Sec. 63.746(c), or Sec. 63.747(d) shall demonstrate
initial compliance with the requirements of this subpart by following
the procedures of paragraph (g)(1), (2), (3), (4), or (5) as applicable
and paragraphs (6), (7), and (8) of this section. When an initial
compliance demonstration is required
[[Page 198]]
by this subpart, the procedures in paragraphs (g)(9) through (g)(14) of
this section shall be used in determining initial compliance with the
provisions of this subpart.
(1) To demonstrate initial and continuous compliance with
Sec. 63.745(d), Sec. 63.746(c), or Sec. 63.747(d) when emissions are
controlled by a dedicated solvent recovery device, each owner or
operator of the affected operation may perform a liquid-liquid HAP or
VOC material balance over rolling 7- to 30-day periods in lieu of
demonstrating compliance through the methods in paragraph (g)(2),
(g)(3), or (g)(4) of this section. Results of the material balance
calculations performed to demonstrate initial compliance shall be
submitted to the Administrator with the notification of compliance
status required by Sec. 63.9(h) and by Sec. 63.753 (c)(1)(iv),
(d)(3)(i), and (e)(3). When demonstrating compliance by this procedure,
Sec. 63.7(e)(3) of subpart A does not apply. The amount of liquid HAP or
VOC applied and recovered shall be determined as discussed in paragraph
(g)(1)(iii) of this section. The overall HAP or VOC emission reduction

zero.
(ii) The measurement techniques of paragraph (g)(1)(i)(A) of this
section shall be submitted to the Administrator for approval with the
notification of performance test required under Sec. 63.7(b).
(iii) Each owner or operator demonstrating compliance by the test
method described in paragraph (g)(1) of this section shall:
(A) Measure the amount of coating or stripper as applied;
(B) Determine the VOC or HAP content of all coating and stripper
applied using the test method specified in Sec. 63.750(c) (1) through
(3) or (e) (1) and (2) of this section;
(C) Install, calibrate, maintain, and operate, according to the
manufacturer's specifications, a device that indicates the amount of HAP
or VOC recovered by the solvent recovery device over rolling 7- to 30-
day periods; the device shall be certified by the manufacturer to be
accurate to within 2.0 percent, and this certification shall
be kept on record;
(D) Measure the amount of HAP or VOC recovered; and
(E) Calculate the overall HAP or VOC emission reduction (R) for
rolling 7- to 30-day periods using equation 9.

or Sec. 63.747(d) when affected HAP emission points are controlled by a
fixed-bed carbon adsorption system with individual exhaust stacks for

source shall perform a gaseous emission test using the following
procedures:

determined by the applicable test methods and procedures specified in
Sec. 63.750(g) (9) through (14);
(ii) Assure that all HAP emissions from the affected HAP emission

Sec. 63.746(c), or Sec. 63.747(d).
(4) An alternative method of demonstrating compliance with
Sec. 63.745(d), Sec. 63.746(c), or Sec. 63.747(d) is the installation of
a total enclosure around the affected HAP emission point(s) and the
ventilation of all HAP emissions from the total enclosure to a control
device with the efficiency specified in paragraph (g)(4)(iii) of this

described in paragraphs (g)(1), (g)(2), and (g)(3) of this section are
not required. Instead, each owner or operator of an affected source
shall:
(i) Demonstrate that a total enclosure is installed. An enclosure
that meets the requirements in paragraphs (g)(4)(i) (A) through (D) of
this section shall be considered a total enclosure. The owner or

[[Page 200]]
that does not meet these requirements may apply to the Administrator for
approval of the enclosure as a total enclosure on a case-by-case basis.
The enclosure shall be considered a total enclosure if it is
demonstrated to the satisfaction of the Administrator that all HAP
emissions from the affected HAP emission point(s) are contained and

(1) All forced makeup air ducts and all exhaust ducts are
constructed so that the volumetric flow rate in each can be accurately
determined by the test methods and procedures specified in
Sec. 63.750(g) (10) and (11); volumetric flow rates shall be calculated
without the adjustment normally made for moisture content; and
(2) Determine FV by equation 14:
[GRAPHIC] [TIFF OMITTED] TR01SE95.016
(D) The air passing through all natural draft openings shall flow
into the enclosure continuously. If FV is less than or equal to 9,000
meters per hour, the continuous inward flow of air shall be verified by
continuous observation using smoke tubes, streamers, tracer gases, or
other means approved by the Administrator over the period that the
volumetric flow rate tests required to determine FV are carried out. If
FV is greater than 9,000 meters per hour, the direction of airflow
through the natural draft openings shall be presumed to be inward at all
times without verification.
(ii) Determine the control device efficiency using equation 10 or
equations 12 and 13, as applicable, and the test methods and procedures
specified in Sec. 63.750(g) (9) through (14).
(iii) Compliance shall be achieved if the installation of a total
enclosure is demonstrated and the value of E determined from equation 10
(or the value of Hsys determined from equations 12 and 13, as
applicable) is equal to or greater than the overall HAP control
efficiencies required under Sec. 63.745(d), Sec. 63.746(c), or
Sec. 63.747(d).
(5) When nonregenerative carbon adsorbers are used to comply with
Sec. 63.745(d), Sec. 63.746(c), or Sec. 63.747(d), the owner or operator
may conduct a design evaluation to demonstrate initial compliance in
lieu of following the compliance test procedures of paragraphs (g)(1),
(2), (3), and (4) of this section. The design evaluation shall consider
the vent stream composition, component concentrations, flow rate,
relative humidity, and temperature, and shall establish the design
exhaust vent stream organic compound concentration level, capacity of
the carbon bed, type and working capacity of activated carbon used for
the carbon bed, and design carbon replacement interval based on the
total carbon working capacity of the control device and the emission
point operating schedule.
(6)(i) To demonstrate initial compliance with Sec. 63.745(d),
Sec. 63.746(c), or Sec. 63.747(d) when hard piping or ductwork is used
to direct VOC and HAP emissions from a VOC and HAP source to the control
device, each owner or operator shall demonstrate upon inspection that
the criteria of paragraph (g)(6)(i)(A) and paragraph (g)(6)(i) (B) or
(C) of this section VR/FD are met.
(A) The equipment shall be vented to a control device.
(B) The control device efficiency (E or Hsys, as
applicable) determined using equation 10 or equations 12 and 13,
respectively, and the test methods and procedures specified in
Sec. 63.750(g) (9) through (14), shall be equal to or greater than the
overall HAP control efficiency required by Sec. 63.745(d),
Sec. 63.746(c), or Sec. 63.747(d).

from the affected emission point(s) shall be
[[Page 201]]
vented to the control device and the carbon adsorber shall be
demonstrated, through the procedures of Sec. 63.750(g) (1), (2), (3),
(4), or (5), to meet the requirements of Sec. 63.745(d), Sec. 63.746(c),
or Sec. 63.747(d).

notice of the intended test method to the Administrator for approval
along with the notification of the performance test required under
Sec. 63.7(b). Method selection shall be based on consideration of the

[63 FR 15024, Mar. 27, 1998]
Appendix A to Subpart GG of Part 63--Specialty Coating Definitions
Ablative coating--A coating that chars when exposed to open flame or
extreme temperatures, as would occur during the failure of an engine
casing or during aerodynamic heating. The ablative char surface serves
as an insulative barrier, protecting adjacent components from the heat
or open flame.
Adhesion promoter--A very thin coating applied to a substrate to
promote wetting and form a chemical bond with the subsequently applied
material.
Adhesive bonding primer--A primer applied in a thin film to
aerospace components for the purpose of corrosion inhibition and
increased adhesive bond strength by attachment. There are two categories
of adhesive bonding primers: primers with a design cure at 250 deg.F or
below and primers with a design cure above 250 deg.F.
Aerosol coating--A hand-held, pressurized, nonrefillable container
that expels an adhesive or a coating in a finely divided spray when a
valve on the container is depressed.
Antichafe coating--A coating applied to areas of moving aerospace
components that may rub during normal operations or installation.
Bearing coating--A coating applied to an antifriction bearing, a
bearing housing, or the area adjacent to such a bearing in order to
facilitate bearing function or to protect base material from excessive
wear. A material shall not be classified as a bearing coating if it can
also be classified as a dry lubricative material or a solid film
lubricant.
Bonding maskant--A temporary coating used to protect selected areas
of aerospace parts from strong acid or alkaline solutions during
processing for bonding.
Caulking and smoothing compounds--Semi-solid materials which are
applied by hand application methods and are used to aerodynamically
smooth exterior vehicle surfaces or fill cavities such as bolt hole
accesses. A material shall not be classified as a caulking and smoothing
compound if it can also be classified as a sealant.
Chemical agent-resistant coating (CARC)--An exterior topcoat
designed to withstand exposure to chemical warfare agents or the
decontaminants used on these agents.
Clear coating--A transparent coating usually applied over a colored
opaque coating, metallic substrate, or placard to give improved gloss
and protection to the color coat. In some cases, a clearcoat refers to
any transparent coating without regard to substrate.
Commercial exterior aerodynamic structure primer--A primer used on
aerodynamic components and structures that protrude from the fuselage,
such as wings and attached components, control surfaces, horizontal
stabilizers, vertical fins, wing-to-body fairings, antennae, and landing
gear and doors, for the purpose of extended corrosion protection and
enhanced adhesion.
Commercial interior adhesive--Materials used in the bonding of
passenger cabin interior components. These components must meet the FAA
fireworthiness requirements.
[[Page 221]]
Compatible substrate primer--Includes two categories: compatible
epoxy primer and adhesive primer. Compatible epoxy primer is primer that
is compatible with the filled elastomeric coating and is epoxy based.
The compatible substrate primer is an epoxy-polyamide primer used to
promote adhesion of elastomeric coatings such as impact-resistant
coatings. Adhesive primer is a coating that (1) inhibits corrosion and
serves as a primer applied to bare metal surfaces or prior to adhesive
application, or (2) is applied to surfaces that can be expected to
contain fuel. Fuel tank coatings are excluded from this category.
Corrosion prevention system--A coating system that provides
corrosion protection by displacing water and penetrating mating
surfaces, forming a protective barrier between the metal surface and
moisture. Coatings containing oils or waxes are excluded from this
category.
Critical use and line sealer maskant--A temporary coating, not
covered under other maskant categories, used to protect selected areas
of aerospace parts from strong acid or alkaline solutions such as those
used in anodizing, plating, chemical milling and processing of
magnesium, titanium, high-strength steel, high-precision aluminum
chemical milling of deep cuts, and aluminum chemical milling of complex
shapes. Materials used for repairs or to bridge gaps left by scribing
operations (i.e. line sealer) are also included in this category.
Cryogenic flexible primer--A primer designed to provide corrosion
resistance, flexibility, and adhesion of subsequent coating systems when
exposed to loads up to and surpassing the yield point of the substrate
at cryogenic temperatures (-275 deg.F and below).
Cryoprotective coating--A coating that insulates cryogenic or
subcooled surfaces to limit propellant boil-off, maintain structural
integrity of metallic structures during ascent or re-entry, and prevent

provides a compatible, flexible substrate over bonded sheet rubber and
rubber-type coatings as well as a flexible bridge between the fasteners,
skin, and skin-to-skin joints on outer aircraft skins. This flexible
bridge allows more topcoat flexibility around fasteners and decreases
the chance of the topcoat cracking around the fasteners. The result is

exterior metal surfaces for protection from high temperatures caused by
atmospheric friction or engine exhaust. These materials differ from
ablative coatings in that they are not ``sacrificial.''

system containing as its chief pigment material one or more of the
following: molybdenum, graphite, polytetrafluoroethylene (PTFE), or
other solids that act as a dry lubricant between faying surfaces.
Specialized function coatings--Coatings that fulfill extremely
specific engineering requirements that are limited in application and
are characterized by low volume usage. This category excludes coatings
covered in other Specialty Coating categories.

Subpart HH--National Emission Standards for Hazardous Air Pollutants
From Oil and Natural Gas Production Facilities
Source: 64 FR 32628, June 17, 1999, unless otherwise noted.
Sec. 63.760 Applicability and designation of affected source.
(a) This subpart applies to the owners and operators of the emission
points, specified in paragraph (b) of this section that are located at
oil and natural gas production facilities that meet the
[[Page 223]]
specified criteria in paragraphs (a)(1) and either (a)(2) or (a)(3) of
this section.
(1) Facilities that are major sources of hazardous air pollutants
(HAP) as defined in Sec. 63.761. Emissions for major source
determination purposes can be estimated using the maximum natural gas or
hydrocarbon liquid throughput, as appropriate, calculated in paragraphs
(a)(1)(i) through (iii) of this section. As an alternative to
calculating the maximum natural gas or hydrocarbon liquid throughput,
the owner or operator of a new or existing source may use the facility's
design maximum natural gas or hydrocarbon liquid throughput to estimate
the maximum potential emissions. Other means to determine the facility's
major source status are allowed, provided the information is documented
and recorded to the Administrator's satisfaction. A facility that is
determined to be an area source, but subsequently increases its
emissions or its 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), and becomes a
major source, must comply thereafter with all applicable provisions of
this subpart starting on the applicable compliance date specified in
paragraph (f) 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.
(i) If the owner or operator documents, to the Administrator's
satisfaction, a decline in annual natural gas or hydrocarbon liquid
throughput, as appropriate, each year for the 5 years prior to June 17,
1999, the owner or operator shall calculate the maximum natural gas or
hydrocarbon liquid throughput used to determine maximum potential
emissions according to the requirements specified in paragraph
(a)(1)(i)(A) of this section. In all other circumstances, the owner or
operator shall calculate the maximum throughput used to determine
whether a facility is a major source in accordance with the requirements
specified in paragraph (a)(1)(i)(B) of this section.
(A) The maximum natural gas or hydrocarbon liquid throughput is the
average of the annual natural gas or hydrocarbon liquid throughput for
the 3 years prior to June 17, 1999, multiplied by a factor of 1.2.
(B) The maximum natural gas or hydrocarbon liquid throughput is the
highest annual natural gas or hydrocarbon liquid throughput over the 5
years prior to June 17, 1999, multiplied by a factor of 1.2.
(ii) The owner or operator shall maintain records of the annual
facility natural gas or hydrocarbon liquid throughput each year and upon
request submit such records to the Administrator. If the facility annual
natural gas or hydrocarbon liquid throughput increases above the maximum
natural gas or hydrocarbon liquid throughput calculated in paragraph
(a)(1)(i)(A) or (a)(1)(i)(B) of this section, the maximum natural gas or
hydrocarbon liquid throughput must be recalculated using the higher
throughput multiplied by a factor of 1.2.
(iii) The owner or operator shall determine the maximum values for
other parameters used to calculate emissions as the maximum for the
period over which the maximum natural gas or hydrocarbon liquid
throughput is determined in accordance with paragraph (a)(1)(i)(A) or
(B) of this section. Parameters shall be based on either highest
measured values or annual average.
(2) Facilities that process, upgrade, or store hydrocarbon liquids
prior to the point of custody transfer.
(3) Facilities that process, upgrade, or store natural gas prior to
the point at which natural gas enters the natural gas transmission and
storage source category or is delivered to a final end user. For the
purposes of this subpart, natural gas enters the natural gas
transmission and storage source category after the natural gas
processing plant, when present. If no natural gas processing plant is
present, natural gas enters the natural gas transmission and storage
source category after the point of custody transfer.
(b) The affected sources to which the provisions of this subpart
apply shall comprise each emission point located at a facility that
meets the criteria
[[Page 224]]
specified in paragraph (a) of this section and listed in paragraphs
(b)(1) through (4) of this section.
(1) Each glycol dehydration unit;
(2) Each storage vessel with the potential for flash emissions;
(3) The group of all ancillary equipment, except compressors,
intended to operate in volatile hazardous air pollutant service (as
defined in Sec. 63.761), which are located at natural gas processing
plants; and
(4) Compressors intended to operate in volatile hazardous air
pollutant service (as defined in Sec. 63.761), which are located at
natural gas processing plants.
(c) [Reserved]
(d) The owner and operator of a facility that does not contain an
affected source as specified in paragraph (b) of this section are not
subject to the requirements of this subpart.
(e) Exemptions. The facilities listed in paragraphs (e)(1) and
(e)(2) of this section are exempt from the requirements of this subpart.
Records shall be maintained as required in Sec. 63.10(b)(3).
(1) A facility that exclusively processes, stores, or transfers
black oil (as defined in Sec. 63.761) is not subject to the requirements
of this subpart. For the purposes of this subpart, a black oil facility
that uses natural gas for fuel or generates gas from black oil shall
qualify for this exemption.
(2) A facility, prior to the point of custody transfer, with a
facilitywide actual annual average natural gas throughput less than 18.4
thousand standard cubic meters per day and a facilitywide actual annual
average hydrocarbon liquid throughput less than 39,700 liters per day.
(f) The owner or operator of an affected source shall achieve
compliance with the provisions of this subpart by the dates specified in
paragraphs (f)(1) and (f)(2) of this section.
(1) The owner or operator of an affected source, the construction or
reconstruction of which commenced before February 6, 1998, shall achieve
compliance with provisions of this 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.
(g) The following provides owners or operators of an affected source
with information on overlap of this subpart with other regulations for
equipment leaks. The owner or operator shall document that they are
complying with other regulations by keeping the records specified in
Sec. 63.774(b)(9).

section, ancillary equipment and compressors that are subject to this
subpart and that are also subject to and controlled under the provisions
of 40 CFR part 60, subpart KKK, are only required to comply with the
requirements of 40 CFR part 60, subpart KKK.

section, ancillary equipment and compressors that are subject to this
subpart and are also subject to and controlled under the provisions of
40 CFR part 61, subpart V, are only required to comply with the
requirements of 40 CFR part 61, subpart V.

(i.e., injected into the flame zone of an enclosed combustion device),
returned back to the process, or sold, then the recovery system used,
including piping, connections, and flow inducing devices, is not
considered to be a control device or closed-vent system.
Cover means a device which is placed on top of or over a material
such that the entire surface area of the material is enclosed and
sealed. A cover may have openings (such as access hatches, sampling
ports, and gauge wells) if those openings are necessary for operation,
inspection, maintenance, or repair of the unit on which the cover is
installed, provided that each opening is closed and sealed when the

gas produced per liter of crude oil or other hydrocarbon liquid.
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

In wet gas service means that a piece of equipment contains or
contacts the field gas before the extraction of natural gas liquids.
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.
Initial producing GOR means the producing standard cubic meters of
gas per liter at the time that the reservoir pressure is above the
bubble point pressure (or dewpoint pressure for a gas).

equipment, for example, following malfunctions or shutdowns.
Major source, as used in this subpart, shall have the same meaning
as in Sec. 63.2, except that:
(1) Emissions from any oil or gas exploration or production well
(with its associated equipment, as defined in this section), and
emissions from any pipeline compressor station or pump station shall not
be aggregated with emissions from other similar units to determine
whether such emission points or stations are major sources, even when
emission points are in a contiguous area or under common control;

part of the same facility, as defined in this section, shall not be
aggregated; and
(3) For facilities that are production field facilities, only HAP
emissions from glycol dehydration units and storage vessels with the
potential for flash emissions shall be aggregated for a major source
determination. For facilities that are not production field facilities,
HAP emissions from all HAP emission units shall be aggregated for a
major source determination.
Natural gas means a naturally occurring mixture of hydrocarbon and
nonhydrocarbon gases found in geologic formations beneath the earth's
surface. The principal hydrocarbon constituent is methane.

ethane, propane, butane, pentane, natural gasoline, and condensate that
are extracted from field natural gas.
Natural gas processing plant (gas plant) means any processing site
engaged in the extraction of natural gas liquids from field gas, or the
fractionation of mixed NGL to natural gas products, or a combination of
both.
No detectable emissions means no escape of HAP from a device or
system to the atmosphere as determined by:

(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 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) Except as provided in paragraph (e) of this section, the owner
or operator shall prepare a startup, shutdown, and 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 startup, shutdown, or
malfunctions does not shield an owner or operator from enforcement
actions.
(e) Owners or operators are not required to prepare a startup,
shutdown, and malfunction plan for any facility where all of the
affected sources meet the exemption criteria specified in
Sec. 63.764(e).

compound in the stream. For process streams that contain nitrogen, air,
or other inerts which are not organic hazardous air pollutants or
volatile organic compounds, the average stream response factor shall be
calculated on an inert-free basis.
(ii) If no instrument is available at the facility that will meet
the performance criteria specified in paragraph (c)(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 (c)(6)(i) of this section.

interface operates with no detectable emissions using
[[Page 237]]
the applicable procedure specified in paragraph (c)(7)(i) or (c)(7)(ii)
of this section.
(i) If an owner or operator chooses not to adjust the detection
instrument readings for the background organic concentration level, then
the maximum organic concentration value measured by the detection
instrument is compared directly to the applicable value for the
potential leak interface as specified in paragraph (c)(8) of this
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 (c)(5) of this
section is compared with the applicable value for the potential leak
interface as specified in paragraph (c)(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 (c)(7) of this section, is less than 500 parts
per million by volume.

[[Page 242]]
(B) After 120 days and no more than 364 days of operation after the
compliance dates specified in Sec. 63.760(f), the owner or operator
shall calculate the average HAP emission reduction as the HAP emission
reduction averaged over the number of days between the current day and
the applicable compliance date. Compliance with the performance
requirements is achieved if the average HAP emission reduction is equal
to or greater than 90.0 percent.
(3) If the owner or operator has data for 365 days or more of
operation, compliance is achieved with the emission limitation specified
in Sec. 63.771(d)(1)(ii) or (e)(3) if the average HAP emission reduction
calculated in paragraph (g)(2)(iii) of this section is equal to or
greater than 95.0 percent.

of emission limitation will achieve a reduction in HAP emissions at
least equivalent to the reduction in HAP emissions from that source
achieved under the applicable requirements in Secs. 63.764 through
63.771, the Administrator will publish in the Federal Register a notice
permitting the use of the alternative means for purposes of compliance
with that requirement. The notice may condition the permission on
requirements related to the operation and maintenance of the alternative
means.

emit, in the aggregate, 9.1 megagrams per year (10 tons per year) or
more of any HAP or 22.7 megagrams per year (25 tons per year) or more of
any combination of HAP.
[[Page 258]]
Maximum allowable thinning ratio means the maximum volume of thinner
that can be added per volume of coating without violating the standards
of Sec. 63.783(a), as determined using Equation 1 of this subpart.
Military exterior specialty coating or Chemical Agent Resistant
Coatings (``CARC'') means any exterior topcoat applied to military or
U.S. Coast Guard vessels that are subject to specific chemical,
biological, and radiological washdown requirements.
Mist specialty coating means any low viscosity, thin film, epoxy

Volatile organic compounds (VOC) is as defined in Sec. 51.100(s) of
this chapter.
Volatile organic hazardous air pollutants (VOHAP) means any compound
listed in or pursuant to section 112(b) of the CAA that contains carbon,
excluding metallic carbides and carbonates. This definition includes VOC
listed as HAP and exempt compounds listed as HAP.
Weld-through preconstruction primer (specialty coating) means a
coating that provides corrosion protection for steel during inventory,
is typically applied at less than 1 mil dry film thickness, does not
require removal prior to welding, is temperature resistant (burn back
from a weld is less than 1.25 centimeters [0.5 inch]), and does not
normally require removal before applying film-building coatings,
including inorganic zinc high-build coatings. When constructing new
vessels, there may be a need to remove areas of weld-through
preconstruction primer due to surface damage or contamination prior to
application of film-building coatings.

Sec. 63.783 Standards.
(a) No owner or operator of any existing or new affected source
shall cause or allow the application of any coating to a ship with an
as-applied VOHAP content exceeding the applicable limit given in Table 2
of this subpart, as determined by the procedures described in
Sec. 63.785 (c)(1) through (c)(4). For the compliance procedures
described in Sec. 63.785 (c)(1) through (c)(3), VOC shall be used as a
surrogate for VOHAP, and Method 24 of Appendix A to 40 CFR part 60 shall
be used as the definitive measure for determining compliance. For the
compliance procedure described in Sec. 63.785(c)(4), an alternative test
method capable of measuring independent VOHAP shall be used to determine
compliance. The method must be submitted to and approved by the
Administrator.
(b) Each owner or operator of a new or existing affected source
shall ensure that:
(1) All handling and transfer of VOHAP-containing materials to and
from containers, tanks, vats, drums, and piping systems is conducted in
a manner that minimizes spills.
(2) All containers, tanks, vats, drums, and piping systems are free
of
[[Page 260]]
cracks, holes, and other defects and remain closed unless materials are
being added to or removed from them.
(c) Approval of alternative means of limiting emissions. (1) The
owner or operator of an affected source may apply to the Administrator
for permission to use an alternative means (such as an add-on control
system) of limiting emissions from coating operations. The application
must include:
(i) An engineering material balance evaluation that provides a
comparison of the emissions that would be achieved using the alternative
means to those that would result from using coatings that comply with
the limits in Table 2 of this subpart, or the results from an emission
test that accurately measures the capture efficiency and control device
efficiency achieved by the control system and the composition of the
associated coatings so that the emissions comparison can be made;
(ii) A proposed monitoring protocol that includes operating
parameter values to be monitored for compliance and an explanation of
how the operating parameter values will be established through a
performance test; and
(iii) Details of appropriate recordkeeping and reporting procedures.
(2) The Administrator shall approve the alternative means of
limiting emissions if, in the Administrator's judgment, postcontrol
emissions of VOHAP per volume applied solids will be no greater than
those from the use of coatings that comply with the limits in Table 2 of
this subpart.
(3) The Administrator may condition approval on operation,
maintenance, and monitoring requirements to ensure that emissions from
the source are no greater than those that would otherwise result from
this subpart.
Sec. 63.784 Compliance dates.
(a) Each owner or operator of an existing affected source shall
comply within two years after the effective date of this subpart.
(b) Each owner or operator of an existing unaffected area source
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 within 1 year after the date of becoming a major source.
(c) Each owner or operator of a new or reconstructed source shall
comply with this subpart according to the schedule in Sec. 63.6(b).
[60 FR 64336, Dec. 15, 1995, as amended at 61 FR 30816, June 18, 1996]
Sec. 63.785 Compliance procedures.
(a) For each batch of coating that is received by an affected
source, the owner or operator shall (see Figure 1 of this section for a
flow diagram of the compliance procedures):
(1) Determine the coating category and the applicable VOHAP limit as
specified in Sec. 63.783(a).
(2) Certify the as-supplied VOC content of the batch of coating. The
owner or operator may use a certification supplied by the manufacturer
for the batch, although the owner or operator retains liability should
subsequent testing reveal a violation. If the owner or operator performs
the certification testing, only one of the containers in which the batch
of coating was received is required to be tested.
(b)(1) In lieu of testing each batch of coating, as applied, the
owner or operator may determine compliance with the VOHAP limits using
any combination of the procedures described in paragraphs (c)(1),
(c)(2), (c)(3), and (c)(4) of this section. The procedure used for each
coating shall be determined and documented prior to application.
(2) The results of any compliance demonstration conducted by the
affected source or any regulatory agency using Method 24 shall take
precedence over the results using the procedures in paragraphs (c)(1),
(c)(2), or (c)(3) of this section.
(3) The results of any compliance demonstration conducted by the
affected source or any regulatory agency using an approved test method
to determine VOHAP content shall take precedence over the results using
the procedures in paragraph (c)(4) of this section.
(c)(1) Coatings to which thinning solvent will not be added. For
coatings to which thinning solvent (or any other material) will not be
added under any circumstance or to which only water is
[[Page 261]]
added, the owner or operator of an affected source shall comply as
follows:
(i) Certify the as-applied VOC content of each batch of coating.
(ii) Notify the persons responsible for applying the coating that no
thinning solvent may be added to the coating by affixing a label to each
container of coating in the batch or through another means described in
the implementation plan required in Sec. 63.787(b).
(iii) If the certified as-applied VOC content of each batch of
coating used during a calendar month is less than or equal to the
applicable VOHAP limit in Sec. 63.783(a) (either in terms of g/L of
coating or g/L of solids), then compliance is demonstrated for that
calendar month, unless a violation is revealed using Method 24 of
Appendix A to 40 CFR part 60.
(2) Coatings to which thinning solvent will be added--coating-by-
coating compliance. For a coating to which thinning solvent is routinely
or sometimes added, the owner or operator shall comply as follows:
(i) Prior to the first application of each batch, designate a single
thinner for the coating and calculate the maximum allowable thinning
ratio (or ratios, if the affected source complies with the cold-weather
limits in addition to the other limits specified in Table 2 of this
subpart) for each batch as follows:
[GRAPHIC] [TIFF OMITTED] TR15DE95.191
where:
R=Maximum allowable thinning ratio for a given batch (L thinner/L
coating as supplied);
Vs=Volume fraction of solids in the batch as supplied (L
solids/L coating as supplied);
VOHAP limit=Maximum allowable as-applied VOHAP content of the coating (g
VOHAP/L solids);
mVOC=VOC content of the batch as supplied [g VOC (including
cure volatiles and exempt compounds on the HAP list)/L coating
(including water and exempt compounds) as supplied];
Dth=Density of the thinner (g/L).
If Vs is not supplied directly by the coating
manufacturer, the owner or operator shall determine Vs as
follows:
[GRAPHIC] [TIFF OMITTED] TR15DE95.192
where:
mvolatiles=Total volatiles in the batch, including VOC,
water, and exempt compounds (g/L coating); and
Davg=Average density of volatiles in the batch (g/L).
The procedures specified in Sec. 63.786(d) may be used to determine
the values of variables defined in this paragraph. In addition, the
owner or operator may choose to construct nomographs, based on Equation
1 of this subpart, similar or identical to the one provided in appendix
B of this subpart as a means of easily estimating the maximum allowable
thinning ratio.
(ii) Prior to the first application of each batch, notify painters
and other persons, as necessary, of the designated thinner and maximum
allowable thinning ratio(s) for each batch of the coating by affixing a
label to each container of coating or through another means described in
the implementation plan required in Sec. 63.787(b).
(iii) By the 15th day of each calendar month, determine the volume
of each batch of the coating used, as supplied, during the previous
month.
(iv) By the 15th day of each calendar month, determine the total
allowable volume of thinner for the coating used during the previous
month as follows:
[GRAPHIC] [TIFF OMITTED] TR15DE95.193
where:
Vth=Total allowable volume of thinner for the previous month
(L thinner);
[[Page 262]]
Vb=Volume of each batch, as supplied and before being
thinned, used during non-cold-weather days of the previous
month (L coating as supplied);
Rcold=Maximum allowable thinning ratio for each batch used
during cold-weather days (L thinner/L coating as supplied);
Vb-cold=Volume of each batch, as supplied and before being
thinned, used during cold-weather days of the previous month
(L coating as supplied);
i=Each batch of coating; and
n=Total number of batches of the coating.
(v) By the 15th day of each calendar month, determine the volume of
thinner actually used with the coating during the previous month.
(vi) If the volume of thinner actually used with the coating
[paragraph (c)(3)(v) of this section] is less than or equal to the total
allowable volume of thinner for the coating [paragraph (c)(3)(iv) of
this section], then compliance is demonstrated for the coating for the
previous month, unless a violation is revealed using Method 24 of
Appendix A to 40 CFR part 60.
(3) Coatings to which the same thinning solvent will be added--group
compliance. For coatings to which the same thinning solvent (or other
material) is routinely or sometimes added, the owner or operator shall
comply as follows:
(i) Designate a single thinner to be added to each coating during
the month and ``group'' coatings according to their designated thinner.
(ii) Prior to the first application of each batch, calculate the
maximum allowable thinning ratio (or ratios, if the affected source
complies with the cold-weather limits in addition to the other limits
specified in Table 2 of this subpart) for each batch of coating in the
group using the equations in paragraph (c)(2) of this section.
(iii) Prior to the first application of each ``batch,'' notify
painters and other persons, as necessary, of the designated thinner and
maximum allowable thinning ratio(s) for each batch in the group by
affixing a label to each container of coating or through another means
described in the implementation plan required in Sec. 63.787(b).
(iv) By the 15th day of each calendar month, determine the volume of
each batch of the group used, as supplied, during the previous month.
(v) By the 15th day of each calendar month, determine the total
allowable volume of thinner for the group for the previous month using
Equation 3 of this subpart.
(vi) By the 15th day of each calendar month, determine the volume of
thinner actually used with the group during the previous month.
(vii) If the volume of thinner actually used with the group
[paragraph (c)(3)(vi) of this section] is less than or equal to the
total allowable volume of thinner for the group [paragraph (c)(3)(v) of
this section], then compliance is demonstrated for the group for the
previous month, unless a violation is revealed using Method 24 of
Appendix A to 40 CFR part 60.
(4) Demonstration of compliance through an alternative (i.e., other
than Method 24 of Appendix A to 40 CFR part 60) test method. The owner
or operator shall comply as follows:
(i) Certify the as-supplied VOHAP content (g VOHAP/L solids) of each
batch of coating.
(ii) If no thinning solvent will be added to the coating, the owner
or operator of an affected source shall follow the procedure described
in Sec. 63.785(c)(1), except that VOHAP content shall be used in lieu of
VOC content.
(iii) If thinning solvent will be added to the coating, the owner or
operator of an affected source shall follow the procedure described in
Sec. 63.785(c)(2) or (3), except that in Equation 1 of this subpart: the
term ``mVOC'' shall be replaced by the term
``mVOHAP,'' defined as the VOHAP content of the coating as
supplied (g VOHAP/L coating) and the term ``Dth'' shall be
replaced by the term ``Dth(VOHAP)'' defined as the average
density of the VOHAP thinner(s) (g/L).
(d) A violation revealed through any approved test method shall
result in a 1-day violation for enforcement purposes. A violation
revealed through the recordkeeping procedures described in paragraphs
(c)(1) through (c)(4) of this section shall result in a 30-day violation
for enforcement purposes, unless the owner or operator provides
sufficient data to demonstrate the specific days during which
noncompliant coatings were applied.
[[Page 263]]
[GRAPHIC] [TIFF OMITTED] TC01MY92.045
Sec. 63.786 Test methods and procedures.
(a) For the compliance procedures described in Sec. 63.785(c) (1)
through (c)(3), Method 24 of 40 CFR part 60, appendix A, is the
definitive method for determining the VOC content of coatings, as
supplied or as applied. When a coating
[[Page 264]]
or thinner contains exempt compounds that are volatile HAP or VOHAP, the
owner or operator shall ensure, when determining the VOC content of a
coating, that the mass of these exempt compounds is included.
(b) For the compliance procedure described in Sec. 63.785(c)(4), the
Administrator must approve the test method for determining the VOHAP
content of coatings and thinners. As part of the approval, the test
method must meet the specified accuracy limits indicated below for
sensitivity, duplicates, repeatability, and reproducibility coefficient
of variation each determined at the 95 percent confidence limit. Each
percentage value below is the corresponding coefficient of variation
multiplied by 2.8 as in the ASTM Method E180-93: Standard Practice for
Determining the Precision of ASTM Methods for Analysis and Testing of
Industrial Chemicals (incorporation by reference--see Sec. 63.14).
(1) Sensitivity. The overall sensitivity must be sufficient to
identify and calculate at least one mass percent of the compounds of
interest based on the original sample. The sensitivity is defined as ten
times the noise level as specified in ASTM Method D3257-93: Standard
Test Methods for Aromatics in Mineral Spirits by Gas Chromatography
(incorporation by reference--see Sec. 63.14). In determining the
sensitivity, the level of sample dilution must be factored in.
(2) Repeatability. First, at the 0.1-5 percent analyte range the
results would be suspect if duplicates vary by more than 6 percent
relative and/or day to day variation of mean duplicates by the same
analyst exceeds 10 percent relative. Second, at greater than 5 percent
analyte range the results would be suspect if duplicates vary by more
than 5 percent relative and/or day to day variation of duplicates by the
same analyst exceeds 5 percent relative.
(3) Reproducibility. First, at the 0.1-5 percent analyte range the
results would be suspect if lab to lab variation exceeds 60 percent
relative. Second, at greater than 5 percent range the results would be
suspect if lab to lab variation exceeds 20 percent relative.
(4) Any test method should include information on the apparatus,
reagents and materials, analytical procedure, procedure for
identification and confirmation of the volatile species in the mixture
being analyzed, precision and bias, and other details to be reported.
The reporting should also include information on quality assurance (QA)
auditing.
(5) Multiple and different analytical techniques must be used for
positive identification if the components in a mixture under analysis
are not known. In such cases a single column gas chromatograph (GC) may
not be adequate. A combination of equipment may be needed such as a GC/
mass spectrometer or GC/infrared system. (If a GC method is used, the
operator must use practices in ASTM Method E260-91 or 96: Standard
Practice for Gas Chromatography [incorporation by reference--see
Sec. 63.14].)
(c) A coating manufacturer or the owner or operator of an affected
source may use batch formulation data as a test method in lieu of Method
24 of Appendix A to 40 CFR part 60 to certify the as-supplied VOC
content of a coating if the manufacturer or the owner or operator has
determined that batch formulation data have a consistent and
quantitatively known relationship to Method 24 results. This
determination shall consider the role of cure volatiles, which may cause
emissions to exceed an amount based solely upon coating formulation
data. Notwithstanding such determination, in the event of conflicting
results, Method 24 of appendix A of 40 CFR part 60 shall take
precedence.
(d) Each owner or operator of an affected source shall use or ensure
that the manufacturer uses the form and procedures mentioned in appendix
A of this subpart to determine values for the thinner and coating
parameters used in Equations 1 and 2 of this subpart. The owner or
operator shall ensure that the coating/thinner manufacturer (or
supplier) provides information on the VOC and VOHAP contents of the
coatings/thinners and the procedure(s) used to determine these values.

d VOHAP limits expressed in units of mass of VOHAP per volume of solids
were derived from the VOHAP limits expressed in units of mass of VOHAP
per volume of coating assuming the coatings contain no water or exempt
compounds and that the volumes of all components within a coating are
additive.
e These limits apply during cold-weather time periods, as defined in
Sec. 63.782. Cold-weather allowances are not given to coatings in
categories that permit less than 40 percent volume solids
(nonvolatiles). Such coatings are subject to the same limits
regardless of weather conditions.

Subpart JJ--National Emission Standards for Wood Furniture Manufacturing
Operations
Source: 60 FR 62936, Dec. 7, 1995, unless otherwise noted.
Sec. 63.800 Applicability.
(a) The affected source to which this subpart applies is each
facility that is engaged, either in part or in whole, in the manufacture
of wood furniture or wood furniture components and that is located at a
plant site that is a major source as defined in 40 CFR part 63, subpart
A, Sec. 63.2. The owner or operator of a source that meets the
definition for an incidental wood furniture manufacturer shall maintain
purchase or usage records demonstrating that the source meets the
definition in Sec. 63.801 of this subpart, but the source shall not be
subject to any other provisions of this subpart.
(b) A source that complies with the limits and criteria specified in
paragraphs (b)(1), (b)(2), or (b)(3) of this section is an area source
for the purposes of this subpart and is not subject to any other
provision of this rule, provided that: In the case of paragraphs (b)(1)
and (b)(2), finishing materials, adhesives, cleaning solvents and
washoff solvents used for wood furniture or wood furniture component
manufacturing operations account for at least 90 percent of annual HAP
emissions at the plant site, and if the plant site has HAP emissions
that do not originate from the listed materials, the owner or operator
shall keep any records necessary to demonstrate that the 90 percent
criterion is being met. A source that initially relies on the limits and
criteria specified in paragraphs (b)(1), (b)(2), and (b)(3) to become an
area source, but subsequently exceeds the relevant limit (without first
obtaining and complying with other limits that keep its potential to
emit hazardous air pollutants 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 in
Sec. 63.800. Nothing in this paragraph (b) 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) The owner or operator of the source uses no more than 250
gallons per month, for every month, of coating, gluing, cleaning, and
washoff materials at the source, including materials used for source
categories other than wood furniture (surface coating), but excluding
materials used in routine janitorial or facility grounds maintenance,
personal uses by employees or other persons, the use of products for the
purpose of maintaining motor vehicles operated by the facility, or the
use of toxic chemicals contained in intake water (used for processing or
noncontact cooling) or intake air (used either as compressed air or for
combustion). The owner or operator shall maintain records of the total
gallons of coating, gluing, cleaning, and washoff materials used each
month, and upon request submit such records to the Administrator. These
records shall be maintained for five years.
(2) The owner or operator of the source uses no more than 3,000
gallons per rolling 12-month period, for every 12-month period, of
coating, gluing, cleaning, and washoff materials at the source,
including materials used for source categories other than wood furniture
(surface coating), but excluding materials used in routine janitorial or
facility grounds maintenance, personal uses by employees or other
persons, the use of products for the purpose of maintaining motor
vehicles operated by the facility, or the use of toxic chemicals
contained in intake water (used for processing or noncontact cooling) or
intake air (used either as compressed air or for combustion). A rolling
12-month period includes the previous 12 months of operation. The owner
or operator of the source shall maintain records of the total gallons of
coating, gluing, cleaning, and washoff materials used each month and the
total gallons used each previous month, and upon request submit such
records to the Administrator. Because records are needed over the
previous set of 12 months, the owner or operator shall keep monthly
records beginning no less than one year before the compliance date
specified in Sec. 63.800(e).
[[Page 272]]
Records shall be maintained for five years.
(3) The source emits no more than 4.5 Mg (5 tons) of any one HAP per
rolling 12-month period and no more than 11.4 Mg (12.5 tons) of any
combination of HAP per rolling 12-month period, and at least 90 percent
of the plantwide emissions per rolling 12-month period are associated
with the manufacture of wood furniture or wood furniture components.
(c) This subpart does not apply to research or laboratory facilities
as defined in Sec. 63.801.
(d) Owners or operators of affected sources shall also comply with
the requirements of subpart A of this part (General Provisions),
according to the applicability of subpart A to such sources, as
identified in Table 1 of this subpart.
(e) The compliance date for existing affected sources that emit less
than 50 tons per year of HAP in 1996 is December 7, 1998. The compliance
date for existing affected sources that emit 50 tons or more of
hazardous air pollutants in 1996 is November 21, 1997. The owner or
operator of an existing area source 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 one year
after becoming a major source.
(f) New affected sources must comply with the provisions of this
standard immediately upon startup or by December 7, 1995, whichever is
later. New area sources that become major sources shall comply with the
provisions of this standard immediately upon becoming a major source.
(g) Reconstructed affected sources are subject to the requirements
for new affected sources. The costs associated with the purchase and
installation of air pollution control equipment (e.g., incinerators,
carbon adsorbers, etc.) are not considered in determining whether the
facility has been reconstructed, unless the control equipment is
required as part of the process (e.g., product recovery). Additionally,
the costs of retrofitting and replacement of equipment that is installed
specifically to comply with this subpart are not considered
reconstruction costs. For example, an affected source may convert to
waterborne coatings to meet the requirements of this subpart. At most
facilities, this conversion will require the replacement of existing
storage tanks, mix equipment, and transfer lines. The cost of replacing
the equipment is not considered in determining whether the facility has
been reconstructed.
[60 FR 62936, Dec. 7, 1995, as amended at 62 FR 30259, June 3, 1997]
Sec. 63.801 Definitions.
(a) All terms used in this subpart that are not defined below have
the meaning given to them in the CAA and in subpart A (General
Provisions) of this part.
Adhesive means any chemical substance that is applied for the
purpose of bonding two surfaces together other than by mechanical means.
Under this subpart, adhesives shall not be considered coatings or
finishing materials. Products used on humans and animals, adhesive tape,
contact paper, or any other product with an adhesive incorporated onto
or in an inert substrate shall not be considered adhesives under this
subpart.
Administrator means the Administrator of the United States
Environmental Protection Agency or his or her authorized representative.
Aerosol adhesive means an adhesive that is dispensed from a
pressurized container as a suspension of fine solid or liquid particles
in gas.
Affected source means a wood furniture manufacturing facility that
is engaged, either in part or in whole, in the manufacture of wood
furniture or wood furniture components and that is located at a plant
site that is a major source as defined in 40 CFR part 63.2, excluding
sources that meet the criteria established in Sec. 63.800(a), (b) and
(c) of this subpart.
Alternative method means any method of sampling and analyzing for an
air pollutant that is not a reference or equivalent method but has been
demonstrated to the Administrator's satisfaction to, in specific cases,
produce results adequate for a determination of compliance.
[[Page 273]]
As applied means the HAP and solids content of the coating or
contact adhesive that is actually used for coating or gluing the
substrate. It includes the contribution of materials used for in-house

applied before graining inks, glazing coats, or other opaque finishing
materials, and is usually topcoated for protection.
Baseline conditions means the conditions that exist prior to an
affected source implementing controls, such as a control system.
Building enclosure means a building housing a process that meets the
requirements of a temporary total enclosure. The EPA Method 204E is used

Certified product data sheet (CPDS) means documentation furnished by
coating or adhesive suppliers or an outside laboratory that provides:
(1) The VHAP content of a finishing material, contact adhesive, or
solvent, by percent weight, measured using the EPA Method 311 (as
promulgated in this subpart), or an equivalent or alternative method (or
formulation data if the coating meets the criteria specified in
Sec. 63.805(a));
(2) The solids content of a finishing material or contact adhesive
by percent weight, determined using data from the EPA Method 24, or an
alternative or equivalent method (or formulation data if the coating
meets the criteria specified in Sec. 63.805 (a)); and
(3) The density, measured by EPA Method 24 or an alternative or
equivalent method. Therefore, the reportable VHAP content shall
represent the maximum aggregate emissions potential of the finishing
material, adhesive, or solvent in concentrations greater than or equal
to 1.0 percent by weight or 0.1 percent for VHAP that are carcinogens,
as defined by the Occupational Safety and Health Administration Hazard
Communication Standard (29 CFR part 1910), as formulated. Only VHAP
present in concentrations greater than or equal to 1.0 percent by
weight, or 0.1 percent for VHAP that are carcinogens, must be reported
on the CPDS. The purpose of the CPDS is to assist the affected source in
demonstrating compliance with the emission limitations presented in
Sec. 63.802.
Note: Because the optimum analytical conditions under EPA Method 311
vary by coating, the coating or adhesive supplier may also choose to
include on the CPDS the optimum analytical conditions for analysis of
the coating, adhesive, or solvent using EPA Method 311. Such information
may include, but not be limited to, separation column, oven temperature,
carrier gas, injection port temperature, extraction solvent, and
internal standard.)
Cleaning operations means operations in which organic HAP solvent is
used to remove coating materials or adhesives from equipment used in
wood furniture manufacturing operations.

pieces together without further clamping, pressure, or airing.
Continuous coater means a finishing system that continuously applies
finishing materials onto furniture parts moving along a conveyor.
Finishing materials that are not transferred to the part are recycled to
a reservoir. Several types of application methods can be used with a
continuous coater including spraying, curtain coating, roll coating, dip
coating, and flow coating.
Continuous compliance means that the affected source is meeting the
emission limitations and other requirements of the rule at all times and
is fulfilling all monitoring and recordkeeping provisions of the rule in
order to demonstrate compliance.

pollutant that is emitted to the air. The device may destroy or secure
the pollutant for subsequent recovery. Includes, but is not limited to,
incinerators, carbon adsorbers, and condensers.
Control device efficiency means the ratio of the pollutant released
by a control device and the pollutant introduced to the control device.

coating is atomized by mixing it with compressed air and applied at an
air pressure greater than 10 pounds per square inch (gauge) at the point
of atomization. Airless and air assisted airless spray technologies are
not conventional air spray because the coating is not atomized by mixing
it with compressed air. Electrostatic spray technology is also not
considered conventional air spray because an electrostatic charge is
employed to attract the coating to the workpiece.
Data quality objective (DQO) approach means a set of approval
criteria that must be met so that data from an alternative test method
can be used in determining the capture efficiency of a control system.
For additional information, see Guidelines for Determining Capture
Efficiency, January 1994. (Docket No. A-93-10, Item No. IV-B-1).

primarily engaged in the manufacture of products other than wood
furniture or wood furniture components and that uses no more than 100
gallons per month of finishing material or adhesives in the manufacture
of wood furniture or wood furniture components.
Incinerator means, for the purposes of this industry, an enclosed
combustion device that thermally oxidizes volatile organic compounds to
CO and CO2. This term does not include devices that burn
municipal or hazardous waste material.
Janitorial maintenance means the upkeep of equipment or building
structures that is not directly related to the manufacturing process,
for example, cleaning of restroom facilities.
Lower confidence limit (LCL) approach means a set of approval
criteria that must be met so that data from an alternative test method
can be used in determining the capture efficiency of a control system.
For additional information, see Guidelines for Determining Capture
Efficiency, January 1994. (Docket No. A-93-10, Item No. IV-B-1).

established for a control device or process parameter that, if achieved
by itself or in combination with one or more other operating parameter
values, determines that an owner or operator has complied with an
applicable emission limit.
Organic HAP solvent means a HAP that is a volatile organic liquid
used for dissolving or dispersing constituents in a coating or contact
adhesive, adjusting the viscosity of a coating or contact adhesive, or
cleaning equipment. When used in a coating or contact adhesive, the

of the dried film.
Overall control efficiency means the efficiency of a control system,
calculated as the product of the capture and control device
efficiencies, expressed as a percentage.
Permanent total enclosure means a permanently installed enclosure
that completely surrounds a source of emissions such that all emissions

protective material used to cover the booth is being replaced, the
affected source shall use no more than 1.0 gallon of organic HAP solvent
per booth to prepare the surface of the booth prior to applying the
booth coating.
(g) Storage requirements. Each owner or operator of an affected

than 1.0 lb VOC/lb solids, as applied;
(2) For touchup and repair under the following conditions:
(i) The touchup and repair occurs after completion of the finishing
operation; or
(ii) The touchup and repair occurs after the application of stain
and before the application of any other type of finishing material, and
the materials used for touchup and repair are applied from a container
that has a volume of no more than 2.0 gallons.
(3) When spray is automated, that is, the spray gun is aimed and
triggered automatically, not manually;
(4) When emissions from the finishing application station are
directed to a control device;
(5) The conventional air gun is used to apply finishing materials
and the
[[Page 280]]
cumulative total usage of that finishing material is no more than 5.0
percent of the total gallons of finishing material used during that
semiannual period; or
(6) The conventional air gun is used to apply stain on a part for
which it is technically or economically infeasible to use any other
spray application technology.
The affected source shall demonstrate technical or economic
infeasibility by submitting to the Administrator a videotape, a
technical report, or other documentation that supports the affected
source's claim of technical or economic infeasibility. The following
criteria shall be used, either independently or in combination, to
support the affected source's claim of technical or economic
infeasibility:
(i) The production speed is too high or the part shape is too
complex for one operator to coat the part and the application station is
not large enough to accommodate an additional operator; or
(ii) The excessively large vertical spray area of the part makes it
difficult to avoid sagging or runs in the stain.
(i) Line cleaning. Each owner or operator of an affected source
shall pump or drain all organic HAP solvent used for line cleaning into
a normally closed container.
(j) Gun cleaning. Each owner or operator of an affected source shall
collect all organic HAP solvent used to clean spray guns into a normally
closed container.
(k) Washoff operations. Each owner or operator of an affected source
shall control emissions from washoff operations by:
(1) Using normally closed tanks for washoff; and
(2) Minimizing dripping by tilting or rotating the part to drain as
much solvent as possible.
(l) Formulation assessment plan for finishing operations. Each owner
or operator of an affected source shall prepare and maintain with the
work practice implementation plan a formulation assessment plan that:
(1) Identifies VHAP from the list presented in Table 5 of this
subpart that are being used in finishing operations by the affected
source;
(2) Establishes a baseline level of usage by the affected source,
for each VHAP identified in paragraph (l)(1) of this section. The
baseline usage level shall be the highest annual usage from 1994, 1995,
or 1996, for each VHAP identified in paragraph (l)(1) of this section.
For formaldehyde, the baseline level of usage shall be based on the
amount of free formaldehyde present in the finishing material when it is
applied. For styrene, the baseline level of usage shall be an estimate
of unreacted styrene, which shall be calculated by multiplying the
amount of styrene monomer in the finishing material, when it is applied,
by a factor of 0.16. Sources using a control device to reduce emissions
may adjust their usage based on the overall control efficiency of the
control system, which is determined using the equation in Sec. 63.805
(d) or (e).
(3) Tracks the annual usage of each VHAP identified in (l)(1) by the
affected source that is present in amounts subject to MSDS reporting as
required by OSHA.
(4) If, after November 1998, the annual usage of the VHAP identified
in paragraph (l)(1) exceeds its baseline level, then the owner or
operator of the affected source shall provide a written notification to
the permitting authority that describes the amount of the increase and
explains the reasons for exceedance of the baseline level. The following
explanations would relieve the owner or operator from further action,
unless the affected source is not in compliance with any State
regulations or requirements for that VHAP:
(i) The exceedance is no more than 15.0 percent above the baseline
level;
(ii) Usage of the VHAP is below the de minimis level presented in
Table 5 of this subpart for that VHAP (sources using a control device to
reduce emissions may adjust their usage based on the overall control
efficiency of the control system, which is determined using the
procedures in Sec. 63.805 (d) or (e);
(iii) The affected source is in compliance with its State's air
toxic regulations or guidelines for the VHAP; or
(iv) The source of the pollutant is a finishing material with a VOC
content
[[Page 281]]
of no more than 1.0 kg VOC/kg solids (1.0 lb VOC/lb solids), as applied.
(5) If none of the above explanations are the reason for the
increase, the owner or operator shall confer with the permitting
authority to discuss the reason for the increase and whether there are
practical and reasonable technology-based solutions for reducing the
usage. The evaluation of whether a technology is reasonable and
practical shall be based on cost, quality, and marketability of the
product, whether the technology is being used successfully by other wood
furniture manufacturing operations, or other criteria mutually agreed
upon by the permitting authority and owner or operator. If there are no
practical and reasonable solutions, the facility need take no further
action. If there are solutions, the owner or operator shall develop a
plan to reduce usage of the pollutant to the extent feasible. The plan
shall address the approach to be used to reduce emissions, a timetable
for implementing the plan, and a schedule for submitting notification of
progress.
(6) If, after November 1998, an affected source uses a VHAP of
potential concern listed in table 6 of this subpart for which a baseline
level has not been previously established, then the baseline level shall
be established as the de minimis level provided in that same table for
that chemical. The affected source shall track the annual usage of each
VHAP of potential concern identified in this paragraph that is present
in amounts subject to MSDS reporting as required by OSHA. If usage of
the VHAP of potential concern exceeds the de minimis level listed in
table 6 of this subpart for that chemical, then the affected source
shall provide an explanation to the permitting authority that documents
the reason for the exceedance of the de minimis level. If the
explanation is not one of those listed in paragraphs (l)(4)(i) through
(l)(4)(iv) of this section, the affected source shall follow the
procedures in paragraph (l)(5) of this section.

shall be used to determine the solids content by weight and the density
of coatings. If it is demonstrated to the satisfaction of the
Administrator that a coating does not release VOC or HAP byproducts
during the cure, for example, all VOC and HAP present in the coating is
solvent, then batch formulation information shall be accepted. The owner
or operator of an affected source may request approval from the
Administrator to use an alternative method for determining the VHAP
content of the coating. In the event of any inconsistency between the
EPA Method 24 or Method 311 test data and a facility's formulation data,
that is, if the EPA Method 24/311 value is higher, the EPA Method 24/311
test shall govern unless after consultation, a regulated source could
demonstrate to the satisfaction of the enforcement agency that the
formulation data were
[[Page 288]]
correct. Sampling procedures shall follow the guidelines presented in
``Standard Procedures for Collection of Coating and Ink Samples for VOC

control efficiency of the control system (R) as the product of the
capture and control device efficiency, using the test methods cited in
Sec. 63.805(c) and the procedures in Sec. 63.805 (d) or (e).
(c) When an initial compliance demonstration is required by
Sec. 63.804 (f)(4) or (f)(6) of this subpart, the procedures in
paragraphs (c)(1) through (c)(6) of this section shall be used in
determining initial compliance with the provisions of this subpart.

applicable, at least twice during each test period.
(d) Each owner or operator of an affected source demonstrating
compliance in accordance with Sec. 63.804 (f)(4) or (f)(6) shall perform
a gaseous emission test using the following procedures:
(1) Construct the overall HAP emission reduction system so that all
volumetric flow rates and total HAP emissions can be accurately
determined by the applicable test methods specified in Sec. 63.805(c)
(1) through (6);
(2) Determine capture efficiency from the affected emission point(s)
by capturing, venting, and measuring all HAP emissions from the affected
emission point(s). During a performance test, the owner or operator
shall isolate affected emission point(s) located in an area with other
nonaffected gaseous emission sources from all other gaseous emission
point(s) by any of the following methods:
(i) Build a temporary total enclosure (see Sec. 63.801) around the
affected emission point(s); or
(ii) Use the building that houses the process as the enclosure (see
Sec. 63.801);
(iii) Use any alternative protocol and test method provided they
meet either the requirements of the data quality objective (DQO)
approach or the lower confidence level (LCL) approach (see Sec. 63.801);
(iv) Shut down all nonaffected HAP emission point(s) and continue to
exhaust fugitive emissions from the affected emission point(s) through
any building ventilation system and other room exhausts such as drying
ovens. All exhaust air must be vented through stacks suitable for
testing; or

a permanent total enclosure shall:
(1) Demonstrate that the total enclosure meets the requirements in
paragraphs (e)(1) (i) through (iv). The owner or operator of an
enclosure that does not meet these requirements may apply to the
Administrator for approval of the enclosure as a total enclosure on a
case-by-case basis. The enclosure shall be considered a total enclosure
if it is demonstrated to the satisfaction of the Administrator that all
HAP emissions from the affected emission point(s) are contained and
vented to the control device. The requirements for automatic approval
are as follows:
(i) The total area of all natural draft openings shall not exceed 5
percent of the total surface area of the total enclosure's walls, floor,
and ceiling;
(ii) All sources of emissions within the enclosure shall be a
minimum of four equivalent diameters away from each natural draft
opening;
(iii) The average inward face velocity (FV) across all natural draft
openings shall be a minimum of 3,600 meters per hour as determined by

Industry
Source: 61 FR 27140, May 30, 1996, unless otherwise.
Sec. 63.820 Applicability.
(a) The provisions of this subpart apply to:
(1) Each new and existing facility that is a major source of
hazardous air pollutants (HAP), as defined in 40 CFR 63.2, at which
publication rotogravure,
[[Page 299]]
product and packaging rotogravure, or wide-web flexographic printing
presses are operated, and
(2) each new and existing facility at which publication rotogravure,
product and packaging rotogravure, or wide-web flexographic printing
presses are operated for which the owner or operator chooses to commit
to, and meets the criteria of paragraphs (a)(2)(i) and (a)(2)(ii) of
this section for purposes of establishing the facility to be an area
source with respect to this subpart:
(i) Use less than 9.1 Mg (10 tons) per each rolling 12-month period
of each HAP at the facility, including materials used for source
categories or purposes other than printing and publishing, and
(ii) Use less than 22.7 Mg (25 tons) per each rolling 12-month
period of any combination of HAP at the facility, including materials
used for source categories or purposes other than printing and
publishing.
(3) Each facility for which the owner or operator chooses to commit
to and meets the criteria stated in paragraph (a)(2) of this section
shall be considered an area source, and is subject only to the
provisions of Sec. 63.829(d) and Sec. 63.830(b)(1) of this subpart.
(4) Each facility for which the owner or operator commits to the
conditions in paragraph (a)(2) of this section may exclude material used
in routine janitorial or facility grounds maintenance, personal uses by
employees or other persons, the use of products for the purpose of
maintaining electric, propane, gasoline and diesel powered motor
vehicles operated by the facility, and the use of HAP contained in
intake water (used for processing or noncontact cooling) or intake air
(used either as compressed air or for combustion).
(5) Each facility for which the owner or operator commits to the
conditions in paragraph (a)(2) of this section to become an area source,
but subsequently exceeds either of the thresholds in paragraph (a)(2) of
this section for any rolling 12-month period (without first obtaining
and complying with other limits that keep its potential to emit HAP
below major source levels), shall be considered in violation of its
commitment for that 12-month period and shall be considered a major
source of HAP beginning the first month after the end of the 12-month
period in which either of the HAP-use thresholds was exceeded. As a
major source of HAP, each such facility would be subject to the
provisions of this subpart as noted in paragraph (a)(1) of this section
and would no longer be eligible to use the provisions of paragraph
(a)(2) of this section, even if in subsequent 12-month periods the
facility uses less HAP than the thresholds in paragraph (a)(2) of this
section.
(6) An owner or operator of an affected source subject to paragraph
(a)(2) of this section who chooses to no longer be subject to paragraph
(a)(2) of this section shall notify the Administrator of such change.
If, by no longer being subject to paragraph (a)(2) of this section, the
facility at which the affected source is located becomes a major source:
(i) The owner or operator of an existing source must continue to
comply with the HAP usage provisions of paragraph (a)(2) of this section
until the source is in compliance with all relevant requirements for
existing affected sources under this subpart;
(ii) The owner or operator of a new source must continue to comply
with the HAP usage provisions of paragraph (a)(2) of this section until
the source is in compliance with all relevant requirements for new
affected sources under this subpart.
(7) Nothing in this paragraph is intended to preclude a facility
from establishing area source status by limiting its potential to emit
through other appropriate mechanisms that may be available through the
permitting authority.
(b) This subpart does not apply to research or laboratory equipment.
Sec. 63.821 Designation of affected sources.

Appendix A to Subpart KK to Part 63--Data Quality Objective and Lower
Confidence Limit Approaches for Alternative Capture Efficiency Protocols
and Test Methods
1. Introduction
1.1 Alternative capture efficiency (CE) protocols and test methods
that satisfy the criteria of either the data quality objective (DQO)
approach or the lower confidence limit (LCL) approach are acceptable
under Sec. 63.827(f). The general criteria for alternative CE protocols
and test methods to qualify under either the DQO or LCL approach are
described in section 2. The DQO approach and criteria specific to the
DQO approach are described in section 3. The LCL approach and criteria
specific to the LCL approach are described in section 4. The recommended
reporting for alternative CE protocols and test methods are presented in
section 5. The recommended recordkeeping for alternative CE protocols
and test methods are presented in section 6.
1.2 Although the Procedures L, G.1, G.2, F.1, and F.2 in
Sec. 52.741 of part 52 were developed for TTE and BE testing, the same
procedures can also be used in an alternative CE protocol. For example,
a traditional liquid/gas mass balance CE protocol could employ
[[Page 324]]
Procedure L to measure liquid VOC input and Procedure G.1 to measure
captured VOC.
2. General Criteria for DQO and LCL Approaches
2.1 The following general criteria must be met for an alternative
capture efficiency protocol and test methods to qualify under the DQO or
LCL approach.
2.2 An alternative CE protocol must consist of at least three valid
test runs. Each test run must be at least 20 minutes long. No test run
can be longer than 24 hours.
2.3 All test runs must be separate and independent. For example,
liquid VOC input and output must be determined independently for each
run. The final liquid VOC sample from one run cannot be the initial
sample for another run. In addition, liquid input for an entire day
cannot be apportioned among test runs based on production.
2.4 Composite liquid samples cannot be used to obtain an ``average
composition'' for a test run. For example, separate initial and final
coating samples must be taken and analyzed for each run; initial and
final samples cannot be combined prior to analysis to derive an
``average composition'' for the test run.
2.5 All individual test runs that result in a CE of greater than
105 percent are invalid and must be discarded.
2.6 If the source can demonstrate to the regulatory agency that a
test run should not be considered due to an identified testing or
analysis error such as spillage of part of the sample during shipping or
an upset or improper operating conditions that is not considered part of
normal operation then the test result for that individual test run may
be discarded. This limited exception allows sources to discard as
``outliers'' certain individual test runs without replacing them with a
valid test run as long as the facility has at least three valid test
runs to use when calculating its DQO or LCL. This exception is limited
solely to test runs involving the types of errors identified above.
2.7 All valid test runs that are conducted must be included in the
average CE determination. The individual test run CE results and average
CE results cannot be truncated (i.e., 105 percent cannot be reported as
100+ percent) for purposes of meeting general or specific criteria for
either the DQO or the LCL. If the DQO is satisfied and the average CE is
greater than 100, then 100 percent CE must be considered the result of
the test.
2.8 Alternative test methods for measuring VOC concentration must
include a three-point calibration of the gas analysis instrument in the
expected concentration range.
3. Data Quality Objective Approach
3.1 The purpose of the DQO is to allow sources to use alternative
CE protocols and test methods while ensuring reasonable precision
consistent with pertinent requirements of the Clean Air Act. In addition
to the general criteria described in section 2, the specific DQO
criterion is that the width of the two-sided 95 percent confidence
interval of the mean measured value must be less than or equal to 10
percent of the mean measured value (see Figure 1). This ensures that 95
percent of the time, when the DQO is met, the actual CE value will be
5 percent of the mean measured value (assuming that the test
protocol is unbiased).

3.2 The DQO calculation is made as follows using Equations 1 and 2:
[GRAPHIC] [TIFF OMITTED] TR30MY96.022

3.3 The sample standard deviation and average CE value are
calculated using Equations 3 and 4 as follows:
[GRAPHIC] [TIFF OMITTED] TR30MY96.024
[GRAPHIC] [TIFF OMITTED] TR30MY96.025
3.4 The DQO criteria are achieved when all of the general criteria
in section 2 are achieved and P 5 percent (i.e., the specific
DQO criterion is achieved). In order to meet this objective, facilities
may have to conduct more than three test runs. Examples of calculating
P, given a finite number of test runs, are shown below. (For purposes of
this example it is assumed that all of the general criteria are met.)
3.5 Facility A conducted a CE test using a traditional liquid/gas
mass balance and submitted the following results and the calculations
shown in Equations 5 and 6:
------------------------------------------------------------------------
Run CE
------------------------------------------------------------------------
1.............................................................. 96.1
2.............................................................. 105.0
3.............................................................. 101.2
------------------------------------------------------------------------
Therefore:
n=3
t0.975=4.30
xavg=100.8
s=4.51
[GRAPHIC] [TIFF OMITTED] TR30MY96.026
[GRAPHIC] [TIFF OMITTED] TR30MY96.027
3.6 Since the facility did not meet the specific DQO criterion,
they ran three more test runs.
------------------------------------------------------------------------
Run CE
------------------------------------------------------------------------
4.............................................................. 93.2
5.............................................................. 96.2
6.............................................................. 87.6
------------------------------------------------------------------------
3.7 The calculations for Runs 1-6 are made as follows using
Equations 7 and 8:
n=6
t0.975=2.57
xavg=96.6
s=6.11
[[Page 326]]
[GRAPHIC] [TIFF OMITTED] TR30MY96.028
[GRAPHIC] [TIFF OMITTED] TR30MY96.029
3.8 The facility still did not meet the specific DQO criterion.
They ran three more test runs with the following results:
------------------------------------------------------------------------
Run CE
------------------------------------------------------------------------
7.............................................................. 92.9
8.............................................................. 98.3
9.............................................................. 91.0
------------------------------------------------------------------------
3.9 The calculations for Runs 1-9 are made as follows using
Equations 9 and 10:
n=9
t0.975=2.31
xavg=95.7
s=5.33
[GRAPHIC] [TIFF OMITTED] TR30MY96.030
[GRAPHIC] [TIFF OMITTED] TR30MY96.031
3.10 Based on these results, the specific DQO criterion is
satisfied. Since all of the general criteria were also satisfied, the
average CE from the nine test runs can be used to determine compliance.
4. Lower Confidence Limit Approach
4.1 The purpose of the LCL approach is to provide sources, that may
be performing much better than their applicable regulatory requirement,
a screening option by which they can demonstrate compliance. The
approach uses less precise methods and avoids additional test runs which
might otherwise be needed to meet the specific DQO criterion while still
being assured of correctly demonstrating compliance. It is designed to
reduce ``false positive'' or so called ``Type II errors'' which may
erroneously indicate compliance where more variable test methods are
employed. Because it encourages CE performance greater than that
required in exchange for reduced compliance demonstration burden, the
sources that successfully use the LCL approach could produce emission
reductions beyond allowable emissions. Thus, it could provide additional
benefits to the environment as well.
4.2 The LCL approach compares the 80 percent (two-sided) LCL for
the mean measured CE value to the applicable CE regulatory requirement.
In addition to the general criteria described in section 2, the specific
LCL criteria are that either the LCL be greater than or equal to the
applicable CE regulatory requirement or that the specific DQO criterion
is met. A more detailed description of the LCL approach follows:
4.3 A source conducts an initial series of at least three runs. The
owner or operator may choose to conduct additional test runs during the
initial test if desired.
4.4 If all of the general criteria are met and the specific DQO
criterion is met, then the average CE value is used to determine
compliance.
4.5 If the data meet all of the general criteria, but do not meet
the specific DQO criterion; and the average CE, using all valid test
runs, is above 100 percent then the test sequence cannot be used to
calculate the LCL. At this point the facility has the option of (a)
conducting more test runs in hopes of meeting the DQO or of bringing the
average CE for all test runs below 100 percent so the LCL can be used or
(b) discarding all previous test data and retesting.
4.6 The purpose of the requirement in Section 4.5 is to protect
against protocols and test methods which may be inherently biased high.
This is important because it is impossible to have an actual CE greater
than 100 percent and the LCL approach only looks at the lower end
variability of the test results. This is different from the DQO which
allows average CE values up to 105 percent because the DQO sets both
upper and lower limits on test variability.
4.7 If at any point during testing the results meet the DQO, the
average CE can be used for demonstrating compliance with the applicable
regulatory requirement. Similarly, if the average CE is below 100
percent then the LCL can be used for demonstrating compliance with the
applicable regulatory requirement without regard to the DQO.
4.8 The LCL is calculated at a 80 percent (two-sided) confidence
level as follows using Equation 11:
[GRAPHIC] [TIFF OMITTED] TR30MY96.032
Where:
LC1=LCL at a 80 percent (two-sided) confidence level.
n=number of valid test runs.
s=sample standard deviation.
t0.90=t-value at the 80-percent (two-sided) confidence level
(see Table 3-1).
xavg=average measured CE value (calculated from all valid
test runs).
4.9 The resulting LC1 is compared to the applicable CE
regulatory requirement. If LC1 exceeds (i.e., is higher than)
the applicable regulatory requirement, then a facility is in initial
compliance. However, if the LC1 is below the CE requirement,
then the facility must conduct additional test runs. After this point
the test results will be evaluated not
[[Page 327]]
only looking at the LCL, but also the DQO of 5 percent of
the mean at a 95 percent confidence level. If the test results with the
additional test runs meet the DQO before the LCL exceeds the applicable
CE regulatory requirement, then the average CE value will be compared to
the applicable CE regulatory requirement for determination of
compliance.
4.10 If there is no specific CE requirement in the applicable
regulation, then the applicable CE regulatory requirement is determined
based on the applicable regulation and an acceptable destruction
efficiency test. If the applicable regulation requires daily compliance
and the latest CE compliance demonstration was made using the LCL
approach, then the calculated LC1 will be the highest CE
value which a facility is allowed to claim until another CE
demonstration test is conducted. This last requirement is necessary to
assure both sufficiently reliable test results in all circumstances and
the potential environmental benefits referenced above.
4.11 An example of calculating the LCL is shown below. Facility B's
applicable regulatory requirement is 85 percent CE. Facility B conducted
a CE test using a traditional liquid/gas mass balance and submitted the
following results and the calculation shown in Equation 12:
------------------------------------------------------------------------
Run CE
------------------------------------------------------------------------
1.............................................................. 94.2
2.............................................................. 97.6
3.............................................................. 90.5
------------------------------------------------------------------------
Therefore:
n=3
t0.90=1.886
xavg=94.1
s=3.55
[GRAPHIC] [TIFF OMITTED] TR30MY96.033
4.12 Since the LC1 of 90.23 percent is above the
applicable regulatory requirement of 85 percent then the facility is in
compliance. The facility must continue to accept the LC1 of
90.23 percent as its CE value until a new series of valid tests is
conducted. (The data generated by Facility B do not meet the specific
DQO criterion.)
5. Recommended Reporting for Alternative CE Protocols
5.1 If a facility chooses to use alternative CE protocols and test
methods that satisfy either the DQO or LCL and the additional criteria
in section 4., the following information should be submitted with each
test report to the appropriate regulatory agency:
1. A copy of all alternative test methods, including any changes to
the EPA reference methods, QA/QC procedures and calibration procedures.
2. A table with information on each liquid sample, including the
sample identification, where and when the sample was taken, and the VOC
content of the sample;
3. The coating usage for each test run (for protocols in which the

or cause to be discharged into the atmosphere emissions of TF from any
potline associated with the modified potroom group, reconstructed
potroom group, or new potroom group that exceed the lower emission limit
calculated in paragraph (b) of this section, except that emissions less
than the upper limit calculated in paragraph (c) of this section will be
considered in compliance if the owner or operator demonstrates that
exemplary operation and maintenance procedures were used with respect to

groups using the procedures, equations, and test methods in
Secs. 63.847, 63.848, and 63.849.
[[Page 333]]
(2) Determine the emission rate of TF in kg/Mg (lb/ton) from
sampling secondary emissions and the primary control system for potroom
groups or sections of potroom groups within the potline that are not new
potroom groups, modified potroom groups, or reconstructed potroom groups
according to paragraphs (g)(2)(i) or (g)(2)(ii) of this section.
(i) Determine the mass emission rate of TF in kg/Mg (lb/ton) from at
least one potroom group within the potline that is not a new potroom
group, modified potroom group, or reconstructed potroom group using the
procedures, equations, and test methods in Secs. 63.847, 63.848, and
63.849, or
(ii) Use the results of the testing required by paragraph (g)(1) of
this section to represent the entire potline based on a demonstration
that the results are representative of the entire potline.
Representativeness shall be based on showing that all of the potroom
groups associated with the potline are substantially equivalent in terms
of their structure, operability, type of emissions, volume of emissions,
and concentration of emissions.
(3) Calculate the TF emissions for the potline in kg/Mg (lb/ton)
based on the production-weighted average of the TF emission rates from
paragraphs (g)(1) and (g)(2) of this section using the following
equation:
E=f1 x EPG1 = (1-f1) x EPL
where:
E=the TF emission rate for the entire potline, kg/Mg (lb/ton);
f1=the fraction of the potline's total aluminum production
rate that is contained within all modified potroom groups,
reconstructed potroom groups, and new potroom groups;
EPG1=the TF emission rate from paragraph (g)(1) of this
section for all modified potroom groups, reconstructed potroom
groups, and new potroom groups, kg/Mg (lb/ton); and
EPL=the TF emission rate for the balance of the potline from
paragraph (g)(2) of this section, kg/Mg (lb/ton).
Compliance is demonstrated when TF emissions for the potline meet
the requirements in paragraph (e) of this section.
(4) As an alternative to sampling as required in paragraphs (g)(1)
and (g)(2) of this section, the owner or operator may perform
representative sampling of the entire potline subject to the approval of
the applicable regulatory authority. Such sampling shall provide
coverage by the sampling equipment of both the new, modified, or
reconstructed potroom group and the balance of the potline. The coverage
for the new, modified, or reconstructed potroom group must meet the
criteria specified in the reference methods in Sec. 63.849. TF emissions
shall be determined for the potline using the procedures, equations, and
test methods in Secs. 63.847, 63.848, and 63.849. Compliance is
demonstrated when TF emissions for the potline meet the requirements in
paragraph (e) of this section.
(h) Opacity. Except as provided in paragraph (i) of this section,
the owner or operator shall not discharge or cause to be discharged into
the atmosphere from the modified potroom group, reconstructed potroom
group, or new potroom group any emissions of gases that exhibit 10
percent opacity or greater.
(i) Alternative opacity limit. An alternative opacity limit may be
established in place of the opacity limit in paragraph (h) of this
section using the following procedures:
(1) If the regulatory authority finds that a potline is in
compliance with the applicable TF standard for which performance tests
are conducted in accordance with the methods and procedures in
Sec. 63.849 but during the time such performance tests are being
conducted fails to meet any applicable opacity standard, the regulatory
authority shall notify and advise the owner or operator that he/she may
petition the regulatory authority within 10 days of receipt of
notification to make appropriate adjustment to the opacity standard.
(2) The regulatory authority will grant such a petition upon a
demonstration by the owner or operator that the potroom group and
associated air pollution control equipment were operated and maintained
in a manner to minimize the opacity of emissions during the performance
tests; that the performance tests were performed under the conditions
established by the regulatory authority; and that the
[[Page 334]]
potroom group and associated air pollution control equipment were
incapable of being adjusted or operated to meet the applicable opacity
standard.
(3) As indicated by the performance and opacity tests, the
regulatory authority will establish an opacity standard for any potroom
group meeting the requirements in paragraphs (i)(1) and (i)(2) of this
section such that the opacity standard could be met by the potroom group
at all times during which the potline is meeting the TF emission limit.
(4) The alternative opacity limit established in paragraph (i)(3) of
this section shall not be greater than 20 percent opacity.

authority may evaluate based on the approach used in ``Primary Aluminum:
Statistical Analysis of Potline Fluoride Emissions and Alternative
Sampling Frequency'' (EPA-450-86-012, October 1986), which is available
from the National Technical Information Service (NTIS), 5285 Port Royal
Road, Springfield, VA 22161.

monitoring device measures an operating parameter outside the limit(s)
established under Sec. 63.847(h), if visible emissions from an exhaust
stack indicating abnormal operation of a control device are observed by
the owner or operator during the daily inspection required in
Sec. 63.848(g), or if a problem is detected during the daily inspection
of a wet roof scrubber for potline secondary emission control required
in Sec. 63.848(f)(5)(ii); and
(2) The owner or operator shall also keep records of each event as
required by Sec. 63.10(b) and record and report if an action taken
during a startup, shutdown, or malfunction is not consistent with the
procedures in the plan as described in Sec. 63.6(e)(3)(iv).
(d) Excess emissions report. As required by Sec. 63.10(e)(3), the
owner or operator shall submit a report (or a summary report) if
measured emissions are in excess of the applicable standard. The report
shall contain the information specified in Sec. 63.10(e)(3)(v) and be
submitted semiannually unless quarterly reports are required as a result
of excess emissions.
(e) Recordkeeping. The owner or operator shall maintain files of all
information (including all reports and notifications) required by
Sec. 63.10(b) and by this subpart.
(1) The owner or operator must retain each record for at least 5
years following the date of each occurrence, measurement, maintenance,
corrective action, report, or record. The most recent 2 years of records
must be retained at the facility. The remaining 3 years of records may
be retained offsite;
(2) The owner or operator may retain records on microfilm, on a
computer, on computer disks, on magnetic tape, or on microfiche;
(3) The owner or operator may report required information on paper
or on a labeled computer disc using commonly available and compatible
computer software; and
(4) In addition to the general records required by Sec. 63.10(b),
the owner or operator shall maintain records of the following
information:

control device for a paste production plant;
(vi) Records supporting the monitoring of similar potlines
demonstrating that the performance of similar potlines is the same as or
better than that of potlines sampled by manual methods;
(vii) Records supporting a request for reduced sampling of potlines;
(viii) Records supporting the correlation of emissions measured by a
continuous emission monitoring system to emissions measured by manual
methods and the derivation of the alternative emission limit derived
from the measurements;
(ix) The current implementation plan for emission averaging and any
subsequent amendments;
(x) Records, such as a checklist or the equivalent, demonstrating
that the daily inspection of a potline with wet roof scrubbers for
secondary emission control has been performed as required in
Sec. 63.848(f)(5)(ii), including the results of each inspection;
(xi) Records, such as a checklist or the equivalent, demonstrating
that the daily visual inspection of the exhaust stack for each control
device has been performed as required in Sec. 63.848(g), including the
results of each inspection;
(xii) For a potline equipped with an HF continuous emission monitor,
records of information and data required by Sec. 63.10(c);
(xiii) Records documenting the corrective actions taken when the
limit(s) for an operating parameter established under Sec. 63.847(h)
were exceeded, when visible emissions indicating abnormal
[[Page 345]]
operation were observed from a control device stack during a daily
inspection required under Sec. 63.848(g), or when a problem was detected
during the daily inspection of a wet roof scrubber for potline secondary
control required in Sec. 63.848(f)(5)(ii);
(xiv) Records documenting any POM data that are invalidated due to
the installation and startup of a cathode; and
(xv) Records documenting the portion of TF that is measured as
particulate matter and the portion that is measured as gaseous when the
particulate and gaseous fractions are quantified separately using an
approved test method.
Sec. 63.851 Regulatory authority review procedures.
(a) The applicable regulatory authority shall notify the owner or
operator in writing of the need for additional time to review the
submissions in paragraphs (a)(1) through (a)(5) of this section or of
approval or intent to deny approval of the submissions in paragraphs
(a)(1) through (a)(5) of this section within 60 calendar days after
receipt of sufficient information to evaluate the submission. The 60-day
period begins after the owner or operator has been notified that the
submission is complete.
(1) The test plan in Sec. 63.847(b);
(2) Request to change limits for operating parameters in
Sec. 63.847(h)(3);
(3) Request for similar potline monitoring in Sec. 63.848(d)(5);
(4) Request for reduced sampling frequency in Sec. 63.848(e); and
(5) Request for an alternative method in Sec. 63.849(e)(2).
(b) The applicable regulatory authority shall notify the owner or
operator in writing whether the submission is complete within 30
calendar days of receipt of the original submission or within 30 days of
receipt of any supplementary information that is submitted. When a
submission is incomplete, the applicable regulatory authority shall
specify the information needed to complete the submission and shall give
the owner or operator 30 calendar days after receipt of the notification
to provide the information.
