                               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, 2005), 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 viii]]

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, 2001, consult either the List of CFR Sections Affected, 1949-
1963, 1964-1972, 1973-1985, or 1986-2000, published in 11 separate 
volumes. For the period beginning January 1, 2001, 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 202-741-6010.

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.

Subpart QQQ_National Emission Standards for Hazardous Air Pollutants for 
                         Primary Copper Smelting

    Source: 67 FR 40491, June 12, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.1440  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for primary copper smelters. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with all applicable emission limitations, work practice 
standards, and operation and maintenance requirements in this subpart.



Sec. 63.1441  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a primary 
copper smelter that is (or is part of) a major source of hazardous air 
pollutant (HAP) emissions on the first compliance date that applies to 
you, and your primary copper smelter uses batch copper converters as 
defined in Sec. 63.1459. Your primary copper smelter is a major source 
of HAP if it emits or has the potential to emit any single HAP at the 
rate of 10 tons or more per year or any combination of HAP at a rate of 
25 tons or more per year.



Sec. 63.1442  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new and existing affected source at 
your primary copper smelter. The affected sources are each copper 
concentrate dryer, each smelting furnace, each slag cleaning vessel, 
each copper converter department, and the entire group of fugitive 
emission sources, as defined in Sec. 63.1459.
    (b) An affected source at your primary copper smelter is existing if 
you commenced construction or reconstruction of the affected source 
before April 20, 1998.
    (c) An affected source at your primary copper smelter is new if you 
commenced construction or reconstruction of the affected source on or 
after April 20, 1998. An affected source is reconstructed if it meets 
the definition of ``reconstruction'' in Sec. 63.2.



Sec. 63.1443  When do I have to comply with this subpart?

    (a) If you have an existing affected source, you must comply with 
each emission limitation, work practice standard, and operation and 
maintenance requirement in this subpart that applies to you no later 
than June 13, 2005.
    (b) If you have a new affected source and its initial startup date 
is on or before June 12, 2002, you must comply with each emission 
limitation, work practice standard, and operation and maintenance 
requirement in this subpart that applies to you by June 12, 2002.
    (c) If you have a new affected source and its initial startup date 
is after June 12, 2002, you must comply with each emission limitation, 
work practice standard, and operation and maintenance requirement in 
this subpart that applies to you upon initial startup.
    (d) If your primary copper smelter is an area source that becomes a 
major source of HAP, the compliance dates listed in paragraphs (d)(1) 
and (2) of this section apply to you.
    (1) Any portion of the existing primary copper smelter that is a new 
affected source or a new reconstructed source must be in compliance with 
this subpart upon startup.
    (2) All other parts of the primary copper smelter must be in 
compliance with this subpart no later than 3 years after it becomes a 
major source.
    (e) You must meet the notification and schedule requirements in 
Sec. 63.1454. Several of these notifications must be submitted before 
the compliance date for your affected source.

            Emission Limitations and Work Practice Standards



Sec. 63.1444  What emissions limitations and work practice standards 

must I meet for my copper concentrate dryers, smelting furnaces, slag 
cleaning vessels, 
          and copper converter departments?

    (a) Copper concentrate dryers. For each copper concentrate dryer, 
you must

[[Page 28]]

comply with the emission limitation in paragraph (a)(1) or (2) of this 
section that applies to you.
    (1) For each existing copper concentrate dryer, you must not cause 
to be discharged to the atmosphere from the dryer vent any gases that 
contain total particulate matter in excess of 50 milligrams per dry 
standard cubic meter (mg/dscm) as measured using the test methods 
specified in Sec. 63.1450(a).
    (2) For each new copper concentrate dryer, you must not cause to be 
discharged to the atmosphere from the dryer vent any gases that contain 
total particulate matter in excess of 23 mg/dscm as measured using the 
test methods specified in Sec. 63.1450(a).
    (b) Smelting furnaces. For each smelting furnace, you must comply 
with the emission limitations and work practice standards in paragraphs 
(b)(1) and (2) of this section.
    (1) For each smelting furnace, you must not cause to be discharged 
to the atmosphere any process off-gas that contains nonsulfuric acid 
particulate matter in excess of 6.2 mg/dscm as measured using the test 
methods specified in Sec. 63.1450(b). Process off-gas from a smelting 
furnace is generated when copper ore concentrates and fluxes are being 
smelted to form molten copper matte and slag layers.
    (2) For each smelting furnace, you must control the process fugitive 
emissions released when tapping copper matte or slag from the smelting 
furnace according to paragraphs (b)(2)(i) and (ii) of this section.
    (i) At all times when copper matte or slag is tapped from the 
smelting furnace, you must operate a capture system that collects the 
gases and fumes released from the tapping port in use. The design and 
placement of this capture system must be such that the tapping port 
opening, launder, and receiving vessel (e.g., ladle, slag pot) are 
positioned within the confines or influence of the capture system's 
ventilation draft during those times when the copper matte or slag is 
flowing from the tapping port opening.
    (ii) You must not cause to be discharged to the atmosphere from the 
capture system used to comply with paragraph (b)(2)(i) of this section 
any gases that contain total particulate matter in excess of 23 mg/dscm 
as measured using the test methods specified in Sec. 63.1450(a).
    (c) Slag cleaning vessels. For each slag cleaning vessel, you must 
comply with the emission limitations and work practice standards in 
paragraphs (c)(1) through (3) of this section that apply to you.
    (1) For each slag cleaning vessel, except as provided for in 
paragraph (c)(2) of this section, you must not cause to be discharged to 
the atmosphere any process off-gas that contains nonsulfuric acid 
particulate matter in excess of 6.2 mg/dscm as measured using the test 
methods specified in Sec. 63.1450(b).
    (2) As an alternative to complying with the emission limit for 
nonsulfuric acid particulate matter in paragraph (c)(1) of this section, 
for each existing slag cleaning vessel you may choose to comply with the 
emission limit for total particulate matter specified in this paragraph 
(c)(2). You must not cause to be discharged to the atmosphere any 
process off-gas that contains total particulate matter in excess of 46 
mg/dscm as measured using the test methods specified in Sec. 
63.1450(a).
    (3) For each slag cleaning vessel, you must control process fugitive 
emissions released when tapping copper matte or slag from the slag 
cleaning vessel according to paragraphs (c)(3)(i) and (ii) of this 
section.
    (i) At all times when copper matte or slag is tapped from the slag 
cleaning vessel, you must operate a capture system that collects the 
gases and fumes released from the tapping port in use. The design and 
placement of this capture system must be such that the tapping port 
opening, launder, and receiving vessel (e.g., ladle, slag pot) are 
positioned within the confines or influence of the capture system's 
ventilation draft during those times when the copper matte or slag is 
flowing from the tapping port opening.
    (ii) You must not cause to be discharged to the atmosphere from the 
capture system used to comply with paragraph (c)(3)(i) of this section

[[Page 29]]

    (d) Existing copper converter departments. For each existing copper 
converter department, you must comply with the emission limitations and 
work practice standards in paragraphs (d)(1) through (6) of this section 
that apply to you.
    (1) You must operate a capture system that collects the process off 
gas vented from each batch copper converter. At all times when one or 
more batch copper converters are blowing, you must operate the capture 
system according to the written operation and maintenance plan that has 
been prepared according to the requirements in Sec. 63.1447(b).
    (2) If your copper converter department uses Pierce-Smith 
converters, the capture system design must include use of a primary hood 
that covers the entire mouth of the converter vessel when the copper 
converter is positioned for blowing. Additional hoods (e.g., secondary 
hoods) or other capture devices must be included in the capture system 
design as needed to achieve the opacity limit in paragraph (d)(4) of 
this section. The capture system design may use multiple intake and duct 
segments through which the ventilation rates are controlled 
independently of each other, and individual duct segments may be 
connected to separate control devices.
    (3) If your copper converter department uses Hoboken converters, the 
capture system must collect all process off-gas vented during blowing 
through the side-flue intake on each converter vessel.
    (4) You must operate the capture system such that any visible 
emissions exiting the roof monitors or roof exhaust fans on the building 
housing the copper converter department meet the opacity limit as 
specified in paragraphs (d)(4)(i) and (ii) of this section.
    (i) The opacity of any visible emissions exiting the roof monitors 
or roof exhaust fans on the building housing the copper converter 
department must not exceed 4 percent as determined by a performance test 
conducted according to Sec. 63.1450(c).
    (ii) The opacity limit in paragraph (d)(4)(i) of this section 
applies only at those times when a performance test is conducted 
according to Sec. 63.1450(c). The requirements for compliance with 
opacity and visible emission standards specified in Sec. 63.6(h) do not 
apply to this opacity limit.
    (5) You must not cause to be discharged to the atmosphere from any 
Pierce-Smith converter primary hood capture system or Hoboken converter 
side-flue intake capture system any process off-gas that contains 
nonsulfuric acid particulate matter in excess of 6.2 mg/dscm as measured 
using the test methods specified in Sec. 63.1450(b).
    (6) You must not cause to be discharged to the atmosphere from any 
secondary capture system any gases that contain total particulate matter 
in excess of 23 mg/dscm as measured using the test methods specified in 
Sec. 63.1450(a).
    (e) New copper converter departments. For each new copper converter 
department for which construction commenced on or after April 20, 1998, 
the use of batch copper converters is prohibited.
    (f) Baghouses. For each baghouse applied to meet any total 
particulate matter emission limit in paragraphs (a) through (d) of this 
section, you must operate the baghouse such that the bag leak detection 
system does not alarm for more than 5 percent of the total operating 
time in any semiannual reporting period.
    (g) Venturi wet scrubbers. For each venturi wet scrubber applied to 
meet any total particulate matter emission limit in paragraphs (a) 
through (d) of this section, you must maintain the hourly average 
pressure drop and scrubber water flow rate at or above the minimum 
levels established during the initial or subsequent performance test.
    (h) Other control devices. For each control device other than a 
baghouse or venturi wet scrubber applied to meet any total particulate 
matter emission limit in paragraphs (a) through (d) of this section, you 
must operate the control device as specified in paragraphs (h)(1) and 
(2) of this section.
    (1) You must select one or more operating parameters, as appropriate 
for the control device design, that can be used as representative and 
reliable indicators of the control device operation.

[[Page 30]]

    (2) You must maintain the hourly average value for each of the 
selected parameters at or above the minimum level or at or below the 
maximum level, as appropriate for the selected parameter, established 
during the initial or subsequent performance test.



Sec. 63.1445  What work practice standards must I meet for my fugitive 
dust sources?

    (a) You must control particulate matter emissions from fugitive dust 
sources at your primary copper smelter by operating according to a 
written fugitive dust control plan that has been approved by the 
designated authority. For the purpose of complying with this paragraph 
(a) you may use an existing fugitive dust control plan provided that the 
plan complies with the requirements of this section. A fugitive dust 
control plan is considered to be approved if the plan has been 
incorporated in your applicable State implementation plan, and the 
document addresses the fugitive dust sources specified in paragraph (b) 
of this section and includes the information specified in paragraph (c) 
of this section.
    (b) Your fugitive dust control plan must address each of the 
fugitive dust emission sources listed in paragraphs (b)(1) through (6) 
of this section that are located at your primary copper smelter.
    (1) On-site roadways used by trucks or other motor vehicles (e.g., 
front-end loaders) when transporting bulk quantities of fugitive dust 
materials. Paved roads and parking areas that are not used by these 
vehicles do not need to be included in the plan (e.g., employee and 
visitor parking lots).
    (2) Unloading of fugitive dust materials from trucks or railcars.
    (3) Outdoor piles used for storage of fugitive dust materials.
    (4) Bedding areas used for blending copper concentrate and other 
feed constituents.
    (5) Each transfer point in conveying systems used to transport 
fugitive dust materials. These points include, but are not limited to, 
transfer of material from one conveyor belt to another and transfer of 
material to a hopper or bin.
    (6) Other site-specific sources of fugitive dust emissions that the 
Administrator or delegated permitting authority designate to be included 
in your fugitive dust control plan.
    (c) Your fugitive dust control plan must describe the control 
measures you use to control fugitive dust emissions from each source 
addressed in the plan, as applicable and appropriate for your site 
conditions. Examples of control measures include, but are not limited 
to, locating the source inside a building or other enclosure, installing 
and operating a local hood capture system over the source and venting 
the captured gas stream to a control device, placing material stockpiles 
below grade, installing wind screens or wind fences around the source, 
spraying water on the source as weather conditions require, applying 
appropriate dust suppression agents on the source, or combinations of 
these control measures.
    (d) The requirement for you to operate according to a written 
fugitive dust control plan must be incorporated in your operating permit 
that is issued by the designated permitting authority under part 70 of 
this chapter. A copy of your fugitive dust control plan must be sent to 
the designated permitting authority on or before the compliance date for 
your primary copper smelter, as specified in Sec. 63.1443.



Sec. 63.1446  What alternative emission limitation may I meet for my 
combined gas streams?

    (a) For situations where you combine gas streams from two or more 
affected sources for discharge to the atmosphere through a single vent, 
you may choose to meet the requirements in paragraph (b) of this section 
as an alternative to complying with the individual total particulate 
matter emission limits specified in Sec. 63.1444 that apply to you. 
This alternative emission limit for a combined gas stream may be used 
for any combination of the affected source gas steams specified in 
paragraphs (a)(1) through (5) of this section.

                 Operation and Maintenance Requirements



Sec. 63.1447  What are my operation and maintenance requirements?

    (a) As required by Sec. 63.6(e)(1)(i), you must always operate and 
maintain your affected source, including air pollution control and 
monitoring equipment, in a manner consistent with good air pollution 
control practices for minimizing emissions at least to the levels 
required by this subpart.
    (b) You must prepare and operate at all times according to a written 
operation and maintenance plan for each capture system and control 
device subject to standards in Sec. 63.1444 or Sec. 63.1446. The plan 
must address the requirements in paragraphs (b)(1) through (3) of this 
section as applicable to the capture system or control device.
    (1) Preventative maintenance. You must perform preventative 
maintenance for each capture system and control device according to 
written procedures specified in your operation and maintenance plan. The 
procedures must include a preventative maintenance schedule that is 
consistent with the manufacturer's instructions for routine and long-
term maintenance.
    (2) Capture system inspections. You must conduct monthly inspections 
of the equipment components of the capture system that can affect the 
performance of the system to collect the gases and fumes emitted from 
the affected source (e.g., hoods, exposed ductwork, dampers, fans) 
according to written procedures specified in your operation and 
maintenance plan. The inspection procedure must include the requirements 
in paragraphs (b)(2)(i) through (iii) of this section as applicable to 
the capture system or control device.
    (i) Observations of the physical appearance of the equipment to 
confirm the physical integrity of the equipment (e.g., verify by visual 
inspection no holes in ductwork or hoods, no flow constrictions caused 
by dents, or accumulated dust in ductwork).
    (ii) Inspection, and if necessary testing, of equipment components 
to confirm that the component is operating as intended (e.g., verify by 
appropriate measures that flow or pressure sensors, damper plates, 
automated damper switches and motors are operating according to 
manufacture or engineering design specifications).
    (iii) In the event that a defective or damaged component is detected 
during an inspection, you must initiate corrective action according to 
written procedures specified in your operation and maintenance plan to 
correct the defect or deficiency as soon as practicable.
    (3) Copper converter department capture system operating limits. You 
must establish, according to the requirements in paragraph (b)(3)(i) 
through (iii) of this section, operating limits for the capture system 
that are representative and reliable indicators of the performance of 
capture system when it is used to collect the process off-gas vented 
from batch copper converters during blowing.
    (i) Select operating limit parameters appropriate for the capture 
system design that are representative and reliable indicators of the 
performance of the capture system when it is used to collect the process 
off-gas vented from batch copper converters during blowing. At a 
minimum, you must use appropriate operating limit parameters that 
indicate the level of the ventilation draft and the damper position 
settings for the capture system when operating to collect the process 
off-gas from the batch copper converters during blowing. Appropriate 
operating limit parameters for ventilation draft include, but are not 
limited to, volumetric flow rate through each separately ducted hood, 
total volumetric flow rate at the inlet to control device to which the 
capture system is vented, fan motor amperage, or static pressure.

[[Page 33]]

Any parameter for damper position setting may be used that indicates the 
duct damper position relative to the fully open setting.
    (ii) For each operating limit parameter selected in paragraph 
(b)(3)(i) of this section, designate the value or setting for the 
parameter at which the capture system operates during batch copper 
converter blowing. If your blister copper production operations allow 
for more than one batch copper converter to be operating simultaneously 
in the blowing mode, designate the value or setting for the parameter at 
which the capture system operates during each possible batch copper 
converter blowing configuration that you may operate at your smelter 
(i.e., the operating limits with one converter blowing, with two 
converters blowing, with three converters blowing, as applicable to your 
smelter).
    (iii) Include documentation in the plan to support your selection of 
the operating limits established for the capture system. This 
documentation must include a description of the capture system design, a 
description of the capture system operation during blister copper 
production, a description of each selected operating limit parameter, a 
rationale for why you chose the parameter, a description of the method 
used to monitor the parameter according to the requirements in Sec. 
63.1452(a), and the data used to set the value or setting for the 
parameter for each of your batch copper converter configurations.
    (4) Baghouse leak detection corrective actions. In the event a bag 
leak detection system alarm is triggered, you must initiate corrective 
action according to written procedures specified in your operation and 
maintenance plan to determine the cause of the alarm within 1 hour of 
the alarm, initiate corrective action to correct the cause of the 
problem within 24 hours of the alarm, and complete the corrective action 
as soon as practicable. Corrective actions may include, but are not 
limited to, the activities listed in paragraphs (b)(3)(i) through (vi) 
of this section.
    (i) Inspecting the baghouse for air leaks, torn or broken bags or 
filter media, or any other condition that may cause an increase in 
emissions.
    (ii) Sealing off defective bags or filter media.
    (iii) Replacing defective bags or filter media or otherwise 
repairing the control device.
    (iv) Sealing off a defective baghouse compartment.
    (v) Cleaning the bag leak detection system probe, or otherwise 
repair the bag leak detection system.
    (vi) Shutting down the process producing the particulate emissions.

                     General Compliance Requirements



Sec. 63.1448  What are my general requirements for complying with 
this subpart?

    (a) You must be in compliance with the emission limitations, work

sampling equipment and operating procedures in Method 5 or 17 when 
testing a positive pressure baghouse, but you must use the sample 
traverse location and number of sampling points described in Method 5D.
    (2) As an alternative to using the applicable method specified in 
paragraph (a)(1)(v) of this section, you may determine total particulate 
matter emissions from the control device using Method 29 in appendix A 
of part 60 of this chapter provided that you follow the procedures and 
precautions prescribed in Method 29. If the control device is a positive 
pressure baghouse, you must also follow the measurement procedure

scrubber water flow rate for each individual test run. Your operating 
limits are the lowest average pressure drop and scrubber water flow rate 
value in any of the three runs that meet the applicable emission limit.
    (5) For a control device other than a baghouse or venturi wet 
scrubber applied to emissions from an affected source and subject to 
site-specific operating limit(s) in Sec. 63.1444(h) or Sec. 63.1446(e) 
for appropriate, site-specific operating parameters that are

appropriate for the selected operating parameter, measured in any of the 
three runs that meet the applicable emission limit.
    (iv) You must prepare written documentation to support your 
selection of the operating parameters used for the control device. This 
documentation must include a description of each selected parameter, a 
rationale for why you chose the parameter, a description of the method 
used to monitor the parameter, and the data recorded during the 
performance test and used to set the operating limit(s).
    (b) Nonsulfuric acid particulate matter emission limits. You must 
conduct each performance test to determine compliance with the 
nonsulfuric acid particulate matter emission limits in Sec. 63.1444 
that apply to you according to the requirements for representative test 
conditions specified in Sec. 63.7(e)(1) and using the test methods and 
procedures in paragraphs (b)(1) and (2) of this section.
    (1) Determine the concentration of nonsulfuric acid particulate 
matter according to the test methods in appendix A to part 60 of this 
chapter as specified in paragraphs (b)(1)(i) through (v) of this 
section.
    (i) Method 1 to select sampling port locations and the number of 
traverse points. Sampling ports must be located at the outlet of the 
control device and prior to any releases to the atmosphere.
    (ii) Method 2, 2F, or 2G to determine the volumetric flow rate of

the arithmetic mean of the results for the three separate test runs is 
used.
    (c) Copper converter department capture system opacity limit. You 
must conduct each performance test to determine compliance with the 
opacity limit in Sec. 63.1444 using the test methods and procedures in 
paragraphs (c)(1) through (9) of this section.
    (1) You must conduct the performance test during the period when the 
primary copper smelter is operating under conditions representative of 
the smelter's normal blister copper production rate. You may not conduct 
a performance test during periods of startup, shutdown, or malfunction. 
Before conducting the performance test, you must prepare a written test 
plan specifying the copper production conditions to be maintained 
throughout the opacity observation period and including a copy of the 
written documentation you have prepared according to paragraph (a)(3) of 
this section to support the established operating limits for the copper 
converter department capture system. You must submit a copy of the test 
plan for review and approval by the Administrator or delegated 
authority. During the observation period, you must collect appropriate 
process information and copper converter department capture system 
operating information to prepare documentation sufficient to verify that 
all opacity observations were made during the copper production and 
capture system operating conditions specified in the approved test plan.
    (2) You must notify the Administrator or delegated authority before 
conducting the opacity observations to allow the Administrator or 
delegated authority the opportunity to have authorized representatives

the opacity limit using qualified visible emission observers and process 
monitors as described in paragraphs (c)(3)(i) and (ii) of this section.
    (i) Opacity observations must be performed by a sufficient number of 
qualified visible emission observers to obtain two complete concurrent 
sets of opacity readings for the required observation period. Each 
visible emission observer must be certified as a qualified observer by 
the procedure specified in section 3 of Method 9 in appendix A of part 
60 of this chapter. The entire set of readings during the required 
observation period does not need to be made by the same two observers. 
More than two observers may be used to allow for substitutions and 
provide for observer rest breaks. The owner or operator must obtain 
proof of current visible emission reading certification for each 
observer.
    (ii) A person (or persons) familiar with the copper production 
operations conducted at the smelter must serve as the indoor process 
monitor. The indoor process monitor is stationed at a location inside 
the building housing the batch copper converters such that he or she can 
visually observe and record operations that occur in the batch copper 
converter aisle during the times that the visible emission observers are 
making opacity readings. More than one indoor process monitor may be 
used to allow for substitutions and provide for rest breaks.
    (4) You must make all opacity observations using Method 9 in 
appendix A to part 60 of this chapter and following the procedures 
described in paragraphs (c)(4)(i) and (ii) of this section.
    (i) Each visible emission observer must make his or her readings at 
a position from the outside of the building that houses the copper 
converter department such that the observer's line-of-sight is 
approximately perpendicular to the longer axis of the converter 
building, and the observer has an unobstructed view of the building roof 
monitor sections or roof exhaust fan outlets that are positioned over 
each of the batch copper converters inside the building. Opacity 
readings can only be made during those times when the observer's 
position meets the sun orientation and other conditions specified in 
section 2.1 of Method 9.
    (ii) At 15-second intervals, each visible emission observer views 
the building roof monitor sections or roof exhaust fan outlets that are 
positioned over each of the batch copper converters inside the building 
and reads the opacity of the visible plumes. If no plume is visible, the 
observer records zero as the opacity value for the 15-second interval. 
In situations when it is possible for an observer to distinguish two or 
more visible emission plumes from the building roof monitor sections or 
roof exhaust fan outlets, the observer must identify, to the extent 
feasible, the plume having the highest opacity and record his or her 
opacity reading for that plume as the opacity value for the 15-second 
interval.
    (5) You must make opacity observations for a period of sufficient 
duration to obtain a minimum of 120 1-minute intervals during which at 
least one copper converter is blowing and no interferences have occurred 
from other copper production events, as specified in paragraph (c)(7) of 
this section, which generate visible emissions inside the building that 
potentially can interfere with the visible emissions from the converter 
capture systems as seen by the outside observers. To obtain the required 
number of 1-minute intervals, the observation period may be divided into 
two or more segments performed on the same day or on different days if 
conditions prevent the required number of opacity readings from being 
obtained during one continuous time period. Examples of these conditions 
include, but are not limited to, changes in the sun's orientation 
relative to visible emission observers' positions such that the Method 9 
conditions are no longer met or an unexpected thunder storm. If the 
total observation period is divided into two or more segments, all 
opacity observations must be made during the same set of copper 
production conditions described in your approved test plan as required 
by paragraph (c)(1) of this section.

[[Page 37]]

    (6) You must gather indoor process information during all times that 
the visible emission observers are making opacity readings outside the 
building housing the copper converter department. The indoor process 
monitor must continually observe the operations occurring in the copper 
converter department and prepare a written record of his or her 
observations using the procedure specified in paragraphs (c)(6)(i) 
through (iv) of this section.
    (i) At the beginning of each observation period or segment, the 
clock time setting on the watch or clock to be used by the indoor 
process monitor must be synchronized with the clock time settings for 
the timepieces to be used by the outdoor opacity observers.
    (ii) During each period or segment when opacity readings are being 
made by the visible emission observers, the indoor process monitor must 
continuously observe the operations occurring in the copper converter 
department and record his or her observations in a log book, on data 
sheets, or other type of permanent written format.
    (iii) When a batch copper converter is blowing, a record must be 
prepared for the converter that includes, but is not limited to, the 
clock times for when blowing begins and when blowing ends and the 
converter blowing rate. This information may be recorded by the indoor 
process monitor or by a separate, automated computer data system.
    (iv) The process monitor must record each event other than converter 
blowing that occurs in or nearby the converter aisle that he or she 
observes to generate visible emissions inside the building. The recorded 
entry for each event must include, but is not limited to, a description 
of the event and the clock times when the event begins and when the 
event ends.
    (7) You must prepare a summary of the data for the entire 
observation period using the information recorded during the observation 
period by the outdoor visible emission observers and the indoor process 
monitor and the procedure specified in paragraphs (c)(7)(i) through (iv) 
of this section.
    (i) Using the field data sheets, identify the 1-minute clock times 
for which a total of eight opacity readings were made and recorded by 
both observers at 15-second intervals according to the test procedures 
(i.e., a total of four opacity values have been recorded for the 1-
minute interval by each of the two observers). Calculate the average of 
the eight 15-second interval readings recorded on the field data sheets 
by the two observers during the clock time minute interval (add the four 
consecutive 15-second interval opacity readings made by Observer A 
during the specified clock time minute, plus the four consecutive 15-
second interval opacity readings made by Observer B during the same 
clock time minute, and divide the resulting total by eight). Record the 
clock time and the opacity average for the 1-minute interval on a data 
summary sheet. Figure 1 of this subpart shows an example of the format 
for the data summary sheet you may use, but are not required to use.
    (ii) Using the data summary sheets prepared according to paragraph 
(c)(7)(i) of this section and the process information recorded according 
to paragraph (c)(6)(iii) of this section, identify those 1-minute 
intervals for which at least one of the batch copper converters was 
blowing.
    (iii) Using the data summary sheets prepared according to paragraph 
(c)(7)(ii) of this section and the process information recorded 
according to paragraph (c)(6)(iv) of this section, identify the 1-minute 
intervals during which at least one copper converter was blowing but 
none of the interference events listed in paragraphs (c)(7)(iii)(A) 
through (F) of this section occurred. Other ancillary activities not 
listed but conducted in or adjacent to the converter aisle during the 
opacity observations are not considered to be interference events (e.g., 
converter aisle cleaning, placement of smoking ladles or skulls on the 
converter aisle floor).
    (A) Charging of copper matte, reverts, or other materials to a batch 
copper converter;
    (B) Skimming slag or other molten materials from a batch copper 
converter;
    (C) Pouring of blister copper or other molten materials from a batch 
copper converter;

[[Page 38]]

    (D) Return of slag or other molten materials to the flash smelting 
furnace or slag cleaning vessel;
    (E) Roll-out or roll-in of the batch copper converter; or
    (F) Smoke and fumes generated inside the converter building by 
operation of the smelting furnace, the slag cleaning vessel (if used), 
anode refining and casting processes that drift into the copper 
converter department.
    (iv) Using the data summary sheets prepared according to paragraph 
(c)(7)(iii) of this section, up to five 1-minute intervals following an 
interference event may be eliminated from data used for the compliance 
determination calculation specified in paragraph (c)(8) of this section 
by applying a time delay factor. The time delay factor must be a 
constant number of minutes not to exceed 5 minutes that is added to the 
clock time recorded when cessation of the interference event occurs. The 
same time delay factor must be used for all interference events (i.e., a 
constant time delay factor for the smelter of 1 minute, 2 minutes, 3 
minutes, 4 minutes, or 5 minutes). The number of minutes to be used for 
the time delay factor is determined based on the site-specific equipment 
and converter building configuration. An explanation of the rationale 
for selecting the value used for the time delay factor must be prepared 
and included in the test report.
    (8) You must use the data summary prepared in paragraph (c)(7) of 
this section to calculate the average opacity value for a minimum of 120 
1-minute intervals during which at least one copper converter was 
blowing with no interference events as determined according to 
paragraphs (c)(7)(iii) and (iv) of this section. Average opacity is 
calculated using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR12JN02.026

Where

VEave = Average opacity to be used for compliance 
determination (percent);
n = Total number of 1-minute intervals during which at least one copper 
converter was blowing with no interference events as determined 
according to paragraphs (c)(7)(iii) and (iv) of this section (at least 
120 1-minute intervals);
i = 1-minute interval ``i'' during which at least one copper converter 
was blowing with no interference events as determined according to 
paragraphs (c)(7)(iii) and (iv) of this section; and
VEi = Average opacity value calculated for the eight opacity 
readings recorded during 1-minute interval ``i'' (percent).

    (9) You must certify that the copper converter department capture 
system operated during the performance test at the operating limits 
established in your capture system operation and maintenance plan using 
the procedure specified in paragraphs (c)(9)(i) through (iv) of this 
section.
    (i) Concurrent with all opacity observations, measure and record 
values for each of the operating limit parameters in your capture system 
operation and maintenance plan according to the monitoring requirements 
specified in Sec. 63.1452(a).
    (ii) For any dampers that are manually set and remain in the same 
position at all times the capture system is operating, the damper 
position must be visually checked and recorded at the beginning and end 
of each opacity observation period segment.
    (iii) Review the recorded monitoring data. Identify and explain any 
times during batch copper converter blowing when the capture system 
operated outside the applicable operating limits.
    (iv) Certify in your performance test report that during all 
observation period segments, the copper converter department capture 
system was operating at the values or settings established in your 
capture system operation and maintenance plan.

required intervals) at all times an affected source is operating.
    (f) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
in data averages and calculations used to report emission or operating 
levels or to fulfill a minimum data availability requirement, if 
applicable. You must use all the data collected during all other periods 
in assessing compliance.
    (g) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitor to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions.

[[Page 52]]

subject to the provisions of this subpart, is subject to the title V 
permitting requirements under 40 CFR parts 70 and 71, as applicable. The 
permitting authority may defer the affected facility from the title V 
permitting requirements until December 9, 2004, if the secondary 
aluminum production facility is not a major source and is not located at 
a major source as defined under 40 CFR 63.2, 70.2, or 71.2, and is not 
otherwise required to obtain a title V permit. If an affected facility 
receives a deferral from title V permitting requirements under this 
section, the source must submit a title V permit application by December 
9, 2005. The affected facility must continue to comply with the 
provisions of this subpart applicable to area sources, even if a 
deferral from title V permitting requirements has been granted to the 
facility by the permitting authority.
    (f) An aluminum die casting facility, aluminum foundry, or aluminum 
extrusion facility shall be considered to be an area source if it does 
not emit, or have the potential to emit considering controls, 10 tons 
per year or more of any single listed HAP or 25 tons per year of any 
combination of listed HAP from all emission sources which are located in 
a contiguous area and under common control, without regard to whether or 
not such sources are regulated under this subpart or any other subpart. 
In the case of an aluminum die casting facility, aluminum foundry, or 
aluminum extrusion facility which is an area source and is subject to 
regulation under this subpart only because it operates a thermal chip 
dryer, no furnace operated by such a facility shall be deemed to be 
subject to the requirements of this subpart if it melts only clean 
charge, internal scrap, or customer returns.

Sec. 63.1503  Definitions.

    Terms used in this subpart are defined in the Clean Air Act as 
amended (CAA), in Sec. 63.2, or in this section as follows:
    Add-on air pollution control device means equipment installed on a 
process vent that reduces the quantity of a pollutant that is emitted to 
the air.
    Afterburner means an air pollution control device that uses 
controlled flame combustion to convert combustible materials to 
noncombustible gases; also known as an incinerator or a thermal 
oxidizer.
    Aluminum scrap means fragments of aluminum stock removed during 
manufacturing (i.e., machining), manufactured aluminum articles or parts 
rejected or discarded and useful only as material for reprocessing, and 
waste and discarded material made of aluminum.
    Aluminum scrap shredder means a unit that crushes, grinds, or breaks 
aluminum scrap into a more uniform size prior to processing or charging 
to a scrap dryer/delacquering kiln/decoating kiln, or furnace. A bale 
breaker is not an aluminum scrap shredder.
    Bag leak detection system means an instrument that is capable of 
monitoring particulate matter loadings in the exhaust of a fabric filter 
(i.e., baghouse) in order to detect bag failures. A bag leak detection 
system includes, but is not limited to, an instrument that operates on 
triboelectric, light scattering, light transmittance, or other effect to 
monitor relative particulate matter loadings.
    Chips means small, uniformly-sized, unpainted pieces of aluminum 
scrap, typically below 1\1/4\ inches in any dimension, primarily 
generated by turning, milling, boring, and machining of aluminum parts.
    Clean charge means furnace charge materials including molten 
aluminum, T-bar, sow, ingot, billet, pig, alloying elements, aluminum 
scrap known by the owner or operator to be entirely free of paints, 
coatings, and lubricants; uncoated/unpainted aluminum chips that have 
been thermally dried or treated by a centrifugal cleaner; aluminum scrap 
dried at 343 [deg]C (650 [deg]F) or higher; aluminum scrap delacquered/
decoated at 482 [deg]C (900 [deg]F) or higher, and runaround scrap.
    Cover flux means salt added to the surface of molten aluminum in a 
group 1 or group 2 furnace, without agitation of the molten aluminum, 
for the purpose of preventing oxidation.
    Customer returns means any aluminum product which is returned by a 
customer to the aluminum company that originally manufactured the 
product prior to resale of the product or further distribution in 
commerce, and which contains no paint or other solid coatings (i.e., 
lacquers).
    D/F means dioxins and furans.
    Dioxins and furans means tetra-, penta-, hexa-, and octachlorinated 
dibenzo dioxins and furans.
    Dross means the slags and skimmings from aluminum melting and 
refining operations consisting of fluxing agent(s), impurities, and/or 
oxidized and non-oxidized aluminum, from scrap aluminum charged into the 
furnace.
    Dross-only furnace means a furnace, typically of rotary barrel 
design, dedicated to the reclamation of aluminum from dross formed 
during melting, holding, fluxing, or alloying operations carried out in 
other process units. Dross and salt flux are the sole feedstocks to this 
type of furnace.
    Emission unit means a group 1 furnace or in-line fluxer at a 
secondary aluminum production facility.
    Fabric filter means an add-on air pollution control device used to 
capture particulate matter by filtering gas streams through filter 
media; also known as a baghouse.
    Feed/charge means, for a furnace or other process unit that operates 
in batch mode, the total weight of material (including molten aluminum, 
T-bar, sow, ingot, etc.) and alloying agents that enter the furnace 
during an operating cycle. For a furnace or other process unit that 
operates continuously, feed/charge means the weight of material 
(including molten aluminum, T-bar, sow, ingot, etc.) and alloying agents 
that enter the process unit

[[Page 54]]

within a specified time period (e.g., a time period equal to the 
performance test period). The feed/charge for a dross only furnace 
includes the total weight of dross and solid flux.
    Fluxing means refining of molten aluminum to improve product 
quality, achieve product specifications, or reduce material loss, 
including the addition of solvents to remove impurities (solvent flux); 
and the injection of gases such as chlorine, or chlorine mixtures, to 
remove magnesium (demagging) or hydrogen bubbles (degassing). Fluxing 
may be performed in the furnace or outside the furnace by an in-line 
fluxer.
    Furnace hearth means the combustion zone of a furnace in which the 
molten metal is contained.
    Group 1 furnace means a furnace of any design that melts, holds, or 
processes aluminum that contains paint, lubricants, coatings, or other 
foreign materials with or without reactive fluxing, or processes clean 
charge with reactive fluxing.
    Group 2 furnace means a furnace of any design that melts, holds, or 
processes only clean charge and that performs no fluxing or performs 
fluxing using only nonreactive, non-HAP-containing/non-HAP-generating 
gases or agents.
    HCl means, for the purposes of this subpart, emissions of hydrogen 
chloride that serve as a surrogate measure of the total emissions of the 
HAPs hydrogen chloride, hydrogen fluoride and chlorine.
    In-line fluxer means a device exterior to a furnace, located in a 
transfer line from a furnace, used to refine (flux) molten aluminum; 
also known as a flux box, degassing box, or demagging box.
    Internal scrap means all aluminum scrap regardless of the level of 
contamination which originates from castings or extrusions produced by 
an aluminum die casting facility, aluminum foundry, or aluminum 
extrusion facility, and which remains at all times within the control of 
the company that produced the castings or extrusions.
    Lime means calcium oxide or other alkaline reagent.
    Lime-injection means the continuous addition of lime upstream of a 
fabric filter.
    Melting/holding furnace means a group 1 furnace that processes only 
clean charge, performs melting, holding, and fluxing functions, and does 
not transfer molten aluminum to or from another furnace except for 
purposes of alloy changes, off-specification product drains, or 
maintenance activities.
    Operating cycle means for a batch process, the period beginning when 
the feed material is first charged to the operation and ending when all 
feed material charged to the operation has been processed. For a batch 
melting or holding furnace process, operating cycle means the period 
including the charging and melting of scrap aluminum and the fluxing, 
refining, alloying, and tapping of molten aluminum (the period from tap-
to-tap).
    PM means, for the purposes of this subpart, emissions of particulate 
matter that serve as a measure of total particulate emissions and as a 
surrogate for metal HAPs contained in the particulates, including but 
not limited to, antimony, arsenic, beryllium, cadmium, chromium, cobalt, 
lead, manganese, mercury, nickel, and selenium.
    Pollution prevention means source reduction as defined under the 
Pollution Prevention Act of 1990 (e.g., equipment or technology 
modifications, process or procedure modifications, reformulation or 
redesign of products, substitution of raw materials, and improvements in 
housekeeping, maintenance, training, or inventory control), and other 
practices that reduce or eliminate the creation of pollutants through 
increased efficiency in the use of raw materials, energy, water, or 
other resources, or protection of natural resources by conservation.
    Reactive fluxing means the use of any gas, liquid, or solid flux 
(other than cover flux) that results in a HAP emission. Argon and 
nitrogen are not reactive and do not produce HAP.
    Reconstruction means the replacement of components of an affected 
source or emission unit such that the fixed capital cost of the new 
components exceeds 50 percent of the fixed capital cost that would be 
required to construct a comparable new affected source, and it is 
technologically and

[[Page 55]]

economically feasible for the reconstructed source to meet relevant 
standard(s) established in this subpart. Replacement of the refractory 
in a furnace is routine maintenance and is not a reconstruction. The 
repair and replacement of in-line fluxer components (e.g., rotors/
shafts, burner tubes, refractory, warped steel) is considered to be 
routine maintenance and is not considered a reconstruction. In-line 
fluxers are typically removed to a maintenance/repair area and are 
replaced with repaired units. The replacement of an existing in-line 
fluxer with a repaired unit is not considered a reconstruction.
    Residence time means, for an afterburner, the duration of time 
required for gases to pass through the afterburner combustion zone. 
Residence time is calculated by dividing the afterburner combustion zone 
volume in cubic feet by the volumetric flow rate of the gas stream in 
actual cubic feet per second.
    Rotary dross cooler means a water-cooled rotary barrel device that 
accelerates cooling of dross.
    Runaround scrap means scrap materials generated on-site by aluminum 
casting, extruding, rolling, scalping, forging, forming/stamping, 
cutting, and trimming operations and that do not contain paint or solid 
coatings. Uncoated/unpainted aluminum chips generated by turning, 
boring, milling, and similar machining operations may be clean charge if 
they have been thermally dried or treated by a centrifugal cleaner, but 
are not considered to be runaround scrap.
    Scrap dryer/delacquering kiln/decoating kiln means a unit used 
primarily to remove various organic contaminants such as oil, paint, 
lacquer, ink, plastic, and/or rubber from aluminum scrap (including used 
beverage containers) prior to melting.
    Secondary aluminum processing unit (SAPU). An existing SAPU means 
all existing group 1 furnaces and all existing in-line fluxers within a 
secondary aluminum production facility. Each existing group 1 furnace or 
existing in-line fluxer is considered an emission unit within a 
secondary aluminum processing unit. A new SAPU means any combination of 
individual group 1 furnaces and in-line fluxers within a secondary 
aluminum processing facility which either were constructed or 
reconstructed after February 11, 1999, or have been permanently 
redesignated as new emission units pursuant to Sec. 63.1505(k)(6). Each 
of the group 1 furnaces or in-line fluxers within a new SAPU is 
considered an emission unit within that secondary aluminum processing 
unit.
    Secondary aluminum production facility means any establishment using 
clean charge, aluminum scrap, or dross from aluminum production, as the 
raw material and performing one or more of the following processes: 
scrap shredding, scrap drying/delacquering/decoating, thermal chip 
drying, furnace operations (i.e., melting, holding, sweating, refining, 
fluxing, or alloying), recovery of aluminum from dross, in-line fluxing, 
or dross cooling. A secondary aluminum production facility may be 
independent or part of a primary aluminum production facility. For 
purposes of this subpart, aluminum die casting facilities, aluminum 
foundries, and aluminum extrusion facilities are not considered to be 
secondary aluminum production facilities if the only materials they melt 
are clean charge, customer returns, or internal scrap, and if they do 
not operate sweat furnaces, thermal chip dryers, or scrap dryers/
delacquering kilns/decoating kilns. The determination of whether a 
facility is a secondary aluminum production facility is only for 
purposes of this subpart and any regulatory requirements which are 
derived from the applicability of this subpart, and is separate from any 
determination which may be made under other environmental laws and 
regulations, including whether the same facility is a ``secondary metal 
production facility'' as that term is used in 42 U.S.C. Sec. 7479(1) 
and 40 CFR 52.21(b)(1)(i)(A) (``prevention of significant deterioration 
of air quality'').
    Sidewell means an open well adjacent to the hearth of a furnace with 
connecting arches between the hearth and the open well through which 
molten aluminum is circulated between the hearth, where heat is applied 
by burners, and the open well, which is used for charging scrap and 
solid flux or salt to the furnace, injecting fluxing agents, and 
skimming dross.

[[Page 56]]

    Sweat furnace means a furnace used exclusively to reclaim aluminum 
from scrap that contains substantial quantities of iron by using heat to 
separate the low-melting point aluminum from the scrap while the higher 
melting-point iron remains in solid form.
    TEQ means the international method of expressing toxicity 
equivalents for dioxins and furans as defined in ``Interim Procedures 
for Estimating Risks Associated with Exposures to Mixtures of 
Chlorinated Dibenzo-p-Dioxins and -Dibenzofurans (CDDs and CDFs) and 
1989 Update'' (EPA-625/3-89-016), available from the National Technical 
Information Service (NTIS), 5285 Port Royal Road, Springfield, Virginia 
22161, NTIS no. PB 90-145756.
    THC means, for the purposes of this subpart, total hydrocarbon 
emissions that also serve as a surrogate for the emissions of organic 
HAP compounds.
    Thermal chip dryer means a device that uses heat to evaporate oil or 
oil/water mixtures from unpainted/uncoated aluminum chips. Pre-heating 
boxes or other dryers which are used solely to remove water from 
aluminum scrap are not considered to be thermal chip dryers for purposes 
of this subpart.
    Three-day, 24-hour rolling average means daily calculations of the 
average 24-hour emission rate (lbs/ton of feed/charge), over the 3 most 
recent consecutive 24-hour periods, for a secondary aluminum processing 
unit.
    Total reactive chlorine flux injection rate means the sum of the 
total weight of chlorine in the gaseous or liquid reactive flux and the 
total weight of chlorine in the solid reactive chloride flux, divided by 
the total weight of feed/charge, as determined by the procedure in Sec. 
63.1512(o).

counted. If corrective action is required, each alarm shall be counted 
as a minimum of 1 hour. If the owner or operator takes longer than 1 
hour to initiate corrective action, the alarm time shall be counted as 
the actual amount of time taken by the owner or operator to initiate 
corrective action.
    (2) If a continuous opacity monitoring system is used to meet the

with the requirements of this subpart. The owner or operator must comply 
with all of the provisions of the OM&M plan as submitted to the 
permitting authority, unless and until the plan is revised in accordance 
with the following procedures. If the permitting authority determines at 
any time after receipt of the OM&M plan that any revisions of the plan 
are necessary to satisfy the requirements of this section or this 
subpart, the owner or operator must promptly make all necessary 
revisions and resubmit the revised plan. If the owner or operator 
determines that any other revisions of the OM&M plan are necessary, such 
revisions will not become effective until the owner or operator submits 
a description of the changes and a revised plan incorporating them to 
the permitting authority. Each plan must contain the following 
information:
    (1) Process and control device parameters to be monitored to 
determine compliance, along with established operating levels or ranges, 
as applicable, for each process and control device.

    (e) Feed/charge weight. The owner or operator of an affected source 
or emission unit subject to an emission limit in kg/Mg (lb/ton) or 
[micro]g/Mg (gr/ton) of feed/charge must install, calibrate, operate, 
and maintain a device to measure and record the total weight of feed/
charge to, or the aluminum production from, the affected source or 
emission unit over the same operating cycle or time period used in the 
performance test. Feed/charge or aluminum production within SAPUs must 
be measured and recorded on an emission unit-by-emission unit basis. As 
an alternative to a measurement device, the owner or operator may use a 
procedure acceptable to the applicable permitting authority to determine 
the total weight of feed/charge or aluminum production to the affected 
source or emission unit.

compliance with all applicable emission limits and must demonstrate, 
based on documented test results, the relationship between emissions of 
PM, HCl, and D/F and the proposed monitoring parameters for each 
pollutant. Test data must establish the highest level of PM, HCl, and D/
F that will be emitted from the furnace. This may be determined by 
conducting performance tests and monitoring operating parameters while 
charging the furnace with feed/charge materials containing the highest 
anticipated levels of oils and coatings and fluxing at the highest 
anticipated rate. If the permitting authority determines that any 
revisions of the site-specific monitoring plan are necessary to meet the 
requirements of this section or this subpart, the owner or operator must 
promptly make all necessary revisions and resubmit the revised plan to 
the permitting authority.
    (i) The owner or operator of an existing affected source must submit 
the site-specific monitoring plan to the applicable permitting authority 
for review at least 6 months prior to the compliance date.
    (ii) The permitting authority will review and approve or disapprove 
a proposed plan, or request changes to a plan, based on whether the plan 
contains sufficient provisions to ensure continuing compliance with 
applicable emission limits and demonstrates, based on documented test 
results, the relationship between emissions of PM, HCl, and D/F and the 
proposed monitoring parameters for each pollutant. Test data must 
establish the highest level of PM, HCl, and D/F that will be emitted 
from the furnace. Subject to permitting agency approval of the OM&M 
plan, this may be determined by conducting performance tests and

anticipated rate.
    (2) Each site-specific monitoring plan must document each work 
practice, equipment/design practice, pollution prevention practice, or 
other measure used to meet the applicable emission standards.
    (3) Each site-specific monitoring plan must include provisions for 
unit labeling as required in paragraph (c) of this section, feed/charge 
weight measurement (or production weight measurement) as required in 
paragraph (e) of this section and flux weight measurement as required in 
paragraph (j) of this section.
    (4) Each site-specific monitoring plan for a melting/holding furnace 
subject to the clean charge emission standard in Sec. 63.1505(i)(3) 
must include these requirements:
    (i) The owner or operator must record the type of feed/ charge 
(e.g., ingot, thermally dried chips, dried scrap, etc.) for each 
operating cycle or time period used in the performance test; and
    (ii) The owner or operator must submit a certification of compliance 
with the applicable operational standard for clean charge materials in 
Sec. 63.1506(n)(3) for each 6-month reporting period. Each

    (5) If a continuous emission monitoring system is included in a 
site-specific monitoring plan, the plan must include provisions for the 
installation, operation, and maintenance of the system to provide 
quality-assured measurements in accordance with all applicable 
requirements of the general provisions in subpart A of this part.
    (6) If a continuous opacity monitoring system is included in a site-
specific monitoring plan, the plan must include provisions for the 
installation, operation, and maintenance of the system to provide 
quality-assured measurements in accordance with all applicable 
requirements of this subpart.
    (7) If a site-specific monitoring plan includes a scrap inspection 
program for monitoring the scrap contaminant level of furnace feed/

    (1) Procedures for the characterization and documentation of the 
contaminant level of the scrap prior to the performance test.

[[Page 71]]

    (2) Limitations on the furnace feed/charge to scrap of the same 
composition as that used in the performance test. If the performance 
test was conducted with a mixture of scrap and clean charge, limitations 
on the proportion of scrap in the furnace feed/charge to no greater than

    (r) Group 2 furnace. These requirements apply to the owner or 
operator of a new or existing group 2 furnace. The owner or operator 
must:
    (1) Record a description of the materials charged to each furnace, 
including any nonreactive, non-HAP-containing/non-HAP-generating fluxing 
materials or agents.
    (2) Submit a certification of compliance with the applicable 
operational standard for charge materials in Sec. 63.1506(o) for each 
6-month reporting period. Each certification must contain the

    (s) Site-specific requirements for secondary aluminum processing 
units. (1) An owner or operator of a secondary aluminum processing unit 
at a facility must include, within the OM&M plan prepared in accordance 
with Sec. 63.1510(b), the following information:
    (i) The identification of each emission unit in the secondary 
aluminum processing unit;
    (ii) The specific control technology or pollution prevention measure 
to be used for each emission unit in the secondary aluminum processing 
unit and the date of its installation or application;
    (iii) The emission limit calculated for each secondary aluminum 
processing unit and performance test results with supporting 
calculations demonstrating initial compliance with each applicable 
emission limit;
    (iv) Information and data demonstrating compliance for each emission 
unit with all applicable design, equipment, work practice or operational 
standards of this subpart; and
    (v) The monitoring requirements applicable to each emission unit in 
a secondary aluminum processing unit and the monitoring procedures for 
daily calculation of the 3-day, 24-hour rolling average using the 
procedure in Sec. 63.1510(t).
    (2) The SAPU compliance procedures within the OM&M plan may not 
contain any of the following provisions:
    (i) Any averaging among emissions of differing pollutants;
    (ii) The inclusion of any affected sources other than emission units 
in a secondary aluminum processing unit;
    (iii) The inclusion of any emission unit while it is shutdown; or
    (iv) The inclusion of any periods of startup, shutdown, or 
malfunction in emission calculations.
    (3) To revise the SAPU compliance provisions within the OM&M plan 
prior to the end of the permit term, the owner or operator must submit a 
request to the applicable permitting authority containing the 
information required by paragraph (s)(1) of this section and obtain 
approval of the applicable permitting authority prior to implementing 
any revisions.
    (t) Secondary aluminum processing unit. Except as provided in 
paragraph (u) of this section, the owner or operator must calculate and 
record the 3-day, 24-hour rolling average emissions of PM, HCl, and D/F 
for each secondary aluminum processing unit on a daily basis. To 
calculate the 3-day, 24-hour rolling average, the owner or operator 
must:
    (1) Calculate and record the total weight of material charged to 
each emission unit in the secondary aluminum processing unit for each 
24-hour day of operation using the feed/charge weight information 
required in paragraph (e) of this section. If the owner or operator 
chooses to comply on the basis of weight of aluminum produced by the 
emission unit, rather than weight of material charged to the emission 
unit, all performance test emissions results and all calculations must 
be conducted on the aluminum production weight basis.
    (2) Multiply the total feed/charge weight to the emission unit, or 
the weight of aluminum produced by the emission unit, for each emission 
unit for the 24-hour period by the emission rate (in lb/ton of feed/
charge) for that

[[Page 72]]

emission unit (as determined during the performance test) to provide 
emissions for each emission unit for the 24-hour period, in pounds.
    (3) Divide the total emissions for each SAPU for the 24-hour period 
by the total material charged to the SAPU, or the weight of aluminum 
produced by the SAPU over the 24-hour period to provide the daily 
emission rate for the SAPU.
    (4) Compute the 24-hour daily emission rate using Equation 4:
    [GRAPHIC] [TIFF OMITTED] TR23MR00.003
    
Where,

Eday = The daily PM, HCl, or D/F emission rate for the 
secondary aluminum processing unit for the 24-hour period;
Ti = The total amount of feed, or aluminum produced, for 
emission unit i for the 24-hour period (tons or Mg);
ERi = The measured emission rate for emission unit i as 
determined in the performance test (lb/ton or [micro]g/Mg of feed/
charge); and
n = The number of emission units in the secondary aluminum processing 
unit.

    (5) Calculate and record the 3-day, 24-hour rolling average for each 
pollutant each day by summing the daily emission rates for each 
pollutant over the 3 most recent consecutive days and dividing by 3.
    (u) Secondary aluminum processing unit compliance by individual 
emission unit demonstration. As an alternative to the procedures of 
paragraph (t) of this section, an owner or operator may demonstrate, 
through performance tests, that each individual emission unit within the 
secondary aluminum production unit is in compliance with the applicable 
emission limits for the emission unit.
    (v) Alternative monitoring method for lime addition. The owner or 
operator of a lime-coated fabric filter that employs intermittent or 
noncontinuous lime addition may apply to the Administrator for approval 
of an alternative method for monitoring the lime addition schedule and 
rate based on monitoring the weight of lime added per ton of feed/charge 
for each operating cycle or time period used in the performance test. An 
alternative monitoring method will not be approved unless the owner or 
operator provides assurance through data and information that the 
affected source will meet the relevant emission standards on a 
continuous basis.
    (w) Alternative monitoring methods. If an owner or operator wishes 
to use an alternative monitoring method to demonstrate compliance with 
any emission standard in this subpart, other than those alternative 
monitoring methods which may be authorized pursuant to Sec. 
63.1510(j)(5) and Sec. 63.1510(v), the owner or operator may submit an 
application to the Administrator. Any such application will be processed 
according to the criteria and procedures set forth in paragraphs (w)(1) 
through (6) of this section.
    (1) The Administrator will not approve averaging periods other than 
those specified in this section.
    (2) The owner or operator must continue to use the original 
monitoring requirement until necessary data are submitted and approval 
is received to use another monitoring procedure.
    (3) The owner or operator shall submit the application for approval 
of alternate monitoring methods no later than the notification of the 
performance test. The application must contain the information specified 
in paragraphs (w)(3) (i) through (iii) of this section:
    (i) Data or information justifying the request, such as the 
technical or economic infeasibility, or the impracticality of using the 
required approach;
    (ii) A description of the proposed alternative monitoring 
requirements, including the operating parameters to be monitored, the 
monitoring approach and technique, and how the limit is to be 
calculated; and
    (iii) Data and information documenting that the alternative 
monitoring requirement(s) would provide equivalent or better assurance 
of compliance with the relevant emission standard(s).
    (4) The Administrator will not approve an alternate monitoring 
application unless it would provide equivalent or better assurance of 
compliance with

[[Page 73]]

the relevant emission standard(s). Before disapproving any alternate 
monitoring application, the Administrator will provide:
    (i) Notice of the information and findings upon which the intended 
disapproval is based; and
    (ii) Notice of opportunity for the owner or operator to present 
additional supporting information before final action is taken on the 
application. This notice will specify how much additional time is 
allowed for the owner or operator to provide additional supporting 
information.
    (5) The owner or operator is responsible for submitting any 
supporting information in a timely manner to enable the Administrator to 
consider the application prior to the performance test. Neither 
submittal of an application nor the Administrator's failure to approve 
or disapprove the application relieves the owner or operator of the 
responsibility to comply with any provisions of this subpart.
    (6) The Administrator may decide at any time, on a case-by-case 
basis, that additional or alternative operating limits, or alternative 
approaches to establishing operating limits, are necessary to 
demonstrate compliance with the emission standards of this subpart.

Sec. 63.1511  Performance test/compliance demonstration general 
requirements.

    (a) Site-specific test plan. Prior to conducting any performance 
test required by this subpart, the owner or operator must prepare a 
site-specific test plan which satisfies all of the requirements, and 
must obtain approval of the plan pursuant to the procedures, set forth 
in Sec. 63.7(c).
    (b) Initial performance test. Following approval of the site-
specific test plan, the owner or operator must demonstrate initial 
compliance with each applicable emission, equipment, work practice, or 
operational standard for each affected source and emission unit, and 
report the results in the notification of compliance status report as 
described in Sec. 63.1515(b). The owner or operator of any existing 
affected source for which an initial performance test is required to 
demonstrate compliance must conduct this initial performance test no 
later than the date for compliance established by Sec. 63.1501(a). The 
owner or operator of any new affected source for which an initial 
performance test is required must conduct this initial performance test 
within 90 days after the date for compliance established by Sec. 
63.1501(b). Except for the date by which the performance test must be 
conducted, the owner or operator must conduct each performance test in 
accordance with the requirements and procedures set forth in Sec. 
63.7(c). Owners or operators of affected sources located at facilities 
which are area sources are subject only to those performance testing 
requirements pertaining to D/F. Owners or operators of sweat furnaces 
meeting the specifications of Sec. 63.1505(f)(1) are not required to 
conduct a performance test.
    (1) The owner or operator must conduct each test while the affected 
source or emission unit is operating at the highest production level 
with charge materials representative of the range of materials processed 
by the unit and, if applicable, at the highest reactive fluxing rate.
    (2) Each performance test for a continuous process must consist of 3 
separate runs; pollutant sampling for each run must be conducted for the 
time period specified in the applicable method or, in the absence of a 
specific time period in the test method, for a minimum of 3 hours.
    (3) Each performance test for a batch process must consist of three 
separate runs; pollutant sampling for each run must be conducted over 
the entire process operating cycle.
    (4) Where multiple affected sources or emission units are exhausted 
through a common stack, pollutant sampling for each run must be 
conducted over a period of time during which all affected sources or 
emission units complete at least 1 entire process operating cycle or for 
24 hours, whichever is shorter.
    (5) Initial compliance with an applicable emission limit or standard 
is demonstrated if the average of three runs conducted during the 
performance

[[Page 74]]

test is less than or equal to the applicable emission limit or standard.
    (c) Test methods. The owner or operator must use the following 
methods in appendix A to 40 CFR part 60 to determine compliance with the 
applicable emission limits or standards:
    (1) Method 1 for sample and velocity traverses.
    (2) Method 2 for velocity and volumetric flow rate.
    (3) Method 3 for gas analysis.
    (4) Method 4 for moisture content of the stack gas.
    (5) Method 5 for the concentration of PM.
    (6) Method 9 for visible emission observations.
    (7) Method 23 for the concentration of D/F.
    (8) Method 25A for the concentration of THC, as propane.
    (9) Method 26A for the concentration of HCl. Where a lime-injected 
fabric filter is used as the control device to comply with the 90 
percent reduction standard, the owner or operator must measure the 
fabric filter inlet concentration of HCl at a point before lime is 
introduced to the system.
    (d) Alternative methods. The owner or operator may use an 
alternative test method, subject to approval by the Administrator.
    (e) Repeat tests. The owner or operator of new or existing affected 
sources and emission units located at secondary aluminum production 
facilities that are major sources must conduct a performance test every 
5 years following the initial performance test.
    (f) Testing of representative emission units. With the prior 
approval of the permitting authority, an owner or operator may utilize 
emission rates obtained by testing a particular type of group 1 furnace 
which is not controlled by any add-on control device, or by testing an 
in-line flux box which is not controlled by any add-on control device, 
to determine the emission rate for other units of the same type at the 
same facility. Such emission test results may only be considered to be 
representative of other units if all of the following criteria are 
satisfied:
    (1) The tested emission unit must use feed materials and charge 
rates which are comparable to the emission units that it represents;
    (2) The tested emission unit must use the same type of flux 
materials in the same proportions as the emission units it represents;
    (3) The tested emission unit must be operated utilizing the same 
work practices as the emission units that it represents;
    (4) The tested emission unit must be of the same design as the 
emission units that it represents; and
    (5) The tested emission unit must be tested under the highest load 
or capacity reasonably expected to occur for any of the emission units 
that it represents.
    (g) Establishment of monitoring and operating parameter values. The 
owner or operator of new or existing affected sources and emission units 
must establish a minimum or maximum operating parameter value, or an 
operating parameter range for each parameter to be monitored as required 
by Sec. 63.1510 that ensures compliance with the applicable emission 
limit or standard. To establish the minimum or maximum value or range, 
the owner or operator must use the appropriate procedures in this 
section and submit the information required by Sec. 63.1515(b)(4) in 
the notification of compliance status report. The owner or operator may 
use existing data in addition to the results of performance tests to 
establish operating parameter values for compliance monitoring provided 
each of the following conditions are met to the satisfaction of the 
applicable permitting authority:
    (1) The complete emission test report(s) used as the basis of the 
parameter(s) is submitted.
    (2) The same test methods and procedures as required by this subpart 
were used in the test.
    (3) The owner or operator certifies that no design or work practice 
changes have been made to the source, process, or emission control 
equipment since the time of the report.
    (4) All process and control equipment operating parameters required 
to be monitored were monitored as required in this subpart and 
documented in the test report.
    (h) Testing of commonly-ducted units within a secondary aluminum 
processing

[[Page 75]]

unit. When group 1 furnaces and/or in-line fluxers are included in a 
single existing SAPU or new SAPU, and the emissions from more than one 
emission unit within that existing SAPU or new SAPU are manifolded to a 
single control device, compliance for all units within the SAPU is 
demonstrated if the total measured emissions from all controlled and 
uncontrolled units in the SAPU do not exceed the emission limits 
calculated for that SAPU based on the applicable equation in Sec. 
63.1505(k).
    (i) Testing of commonly-ducted units not within a secondary aluminum 
processing unit. With the prior approval of the permitting authority, an 
owner or operator may do combined performance testing of two or more 
individual affected sources or emission units which are not included in 
a single existing SAPU or new SAPU, but whose emissions are manifolded 
to a single control device. Any such performance testing of commonly-
ducted units must satisfy the following basic requirements:
    (1) All testing must be designed to verify that each affected source 
or emission unit individually satisfies all emission requirements 
applicable to that affected source or emission unit;
    (2) All emissions of pollutants subject to a standard must be tested 
at the outlet from each individual affected source or emission unit 
while operating under the highest load or capacity reasonably expected 
to occur, and prior to the point that the emissions are manifolded 
together with emissions from other affected sources or emission units;
    (3) The combined emissions from all affected sources and emission 
units which are manifolded to a single emission control device must be 
tested at the outlet of the emission control device;
    (4) All tests at the outlet of the emission control device must be 
conducted with all affected sources and emission units whose emissions 
are manifolded to the control device operating simultaneously under the 
highest load or capacity reasonably expected to occur; and
    (5) For purposes of demonstrating compliance of a commonly-ducted 
unit with any emission limit for a particular type of pollutant, the 
emissions of that pollutant by the individual unit shall be presumed to 
be controlled by the same percentage as total emissions of that 
pollutant from all commonly-ducted units are controlled at the outlet of 
the emission control device.

67 FR 79817, Dec. 30, 2002]



Sec. 63.1512  Performance test/compliance demonstration requirements 
and procedures.

    (a) Aluminum scrap shredder. The owner or operator must conduct 
performance tests to measure PM emissions at the outlet of the control 
system. If visible emission observations is the selected monitoring 
option, the owner or operator must record visible emission observations 
from each exhaust stack for all consecutive 6-minute periods during the 
PM emission test according to the requirements of Method 9 in appendix A 
to 40 CFR part 60.
    (b) Thermal chip dryer. The owner or operator must conduct a 
performance test to measure THC and D/F emissions at the outlet of the 
control device while the unit processes only unpainted aluminum chips.
    (c) Scrap dryer/delacquering kiln/decoating kiln. The owner or 
operator must conduct performance tests to measure emissions of THC, D/
F, HCl, and PM at the outlet of the control device.
    (1) If the scrap dryer/delacquering kiln/decoating kiln is subject 
to the alternative emission limits in Sec. 63.1505(e), the average 
afterburner operating temperature in each 3-hour block period must be 
maintained at or above 760 [deg]C (1400 [deg]F) for the test.
    (2) The owner or operator of a scrap dryer/delacquering kiln/
decoating kiln subject to the alternative limits in Sec. 63.1505(e) 
must submit a written certification in the notification of compliance 
status report containing the information required by Sec. 
63.1515(b)(7).
    (d) Group 1 furnace with add-on air pollution control devices. (1) 
The owner or operator of a group 1 furnace that processes scrap other 
than clean charge materials with emissions controlled by

[[Page 76]]

a lime-injected fabric filter must conduct performance tests to measure 
emissions of PM and D/F at the outlet of the control device and 
emissions of HCl at the outlet (for the emission limit) or the inlet and 
the outlet (for the percent reduction standard).
    (2) The owner or operator of a group 1 furnace that processes only 
clean charge materials with emissions controlled by a lime-injected 
fabric filter must conduct performance tests to measure emissions of PM 
at the outlet of the control device and emissions of HCl at the outlet 
(for the emission limit) or the inlet and the outlet (for the percent 
reduction standard).
    (3) The owner or operator may choose to determine the rate of 
reactive flux addition to the group 1 furnace and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all reactive flux added to the group 1 furnace is emitted. Under these 
circumstances, the owner or operator is not required to conduct an 
emission test for HCl.
    (4) The owner or operator of a sidewell group 1 furnace that 
conducts reactive fluxing (except for cover flux) in the hearth, or that 
conducts reactive fluxing in the sidewell at times when the level of 
molten metal falls below the top of the passage between the sidewell and 
the hearth, must conduct the performance tests required by paragraph 
(d)(1) or (d)(2) of this section, to measure emissions from both the 
sidewell and the hearth.
    (e) Group 1 furnace (including melting holding furnaces) without 
add-on air pollution control devices. In the site-specific monitoring 
plan required by Sec. 63.1510(o), the owner or operator of a group 1 
furnace (including a melting/holding furnaces) without add-on air 
pollution control devices must include data and information 
demonstrating compliance with the applicable emission limits.
    (1) If the group 1 furnace processes other than clean charge 
material, the owner or operator must conduct emission tests to measure 
emissions of PM, HCl, and D/F at the furnace exhaust outlet.
    (2) If the group 1 furnace processes only clean charge, the owner or 
operator must conduct emission tests to simultaneously measure emissions 
of PM and HCl at the furnace exhaust outlet. A D/F test is not required. 
Each test must be conducted while the group 1 furnace (including a 
melting/holding furnace) processes only clean charge.
    (3) The owner or operator may choose to determine the rate of 
reactive flux addition to the group 1 furnace and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all reactive flux added to the group 1 furnace is emitted. Under these 
circumstances, the owner or operator is not required to conduct an 
emission test for HCl.
    (f) Sweat furnace. Except as provided in Sec. 63.1505(f)(1), the 
owner or operator must measure emissions of D/F from each sweat furnace 
at the outlet of the control device.
    (g) Dross-only furnace. The owner or operator must conduct a 
performance test to measure emissions of PM from each dross-only furnace 
at the outlet of each control device while the unit processes only dross 
and salt flux as the sole feedstock.
    (h) In-line fluxer. (1) The owner or operator of an in-line fluxer 
that uses reactive flux materials must conduct a performance test to 
measure emissions of HCl and PM or otherwise demonstrate compliance in 
accordance with paragraph (h)(2) of this section. If the in-line fluxer 
is equipped with an add-on control device, the emissions must be 
measured at the outlet of the control device.
    (2) The owner or operator may choose to limit the rate at which 
reactive chlorine flux is added to an in-line fluxer and assume, for the 
purposes of demonstrating compliance with the SAPU emission limit, that 
all chlorine in the reactive flux added to the in-line fluxer is emitted 
as HCl. Under these circumstances, the owner or operator is not required 
to conduct an emission test for HCl. If the owner or operator of any in-
line flux box which has no ventilation ductwork manifolded to any outlet 
or emission control device chooses to demonstrate compliance with the 
emission limit for HCl by limiting use of reactive chlorine flux and 
assuming that all chlorine in the flux is emitted as HCl, compliance 
with the

[[Page 77]]

HCl limit shall also constitute compliance with the emission limit for 
PM, and no separate emission test for PM is required. In this case, the 
owner or operator of the unvented in-line flux box must utilize the 
maximum permissible PM emission rate for the in-line flux boxes when 
determining the total emissions for any SAPU which includes the flux 
box.
    (i) Rotary dross cooler. The owner or operator must conduct a 
performance test to measure PM emissions at the outlet of the control 
device.
    (j) Secondary aluminum processing unit. The owner or operator must 
conduct performance tests as described in paragraphs (j)(1) through (3) 
of this section. The results of the performance tests are used to 
establish emission rates in lb/ton of feed/charge for PM and HCl and 
[micro]g TEQ/Mg of feed/charge for D/F emissions from each emission 
unit. These emission rates are used for compliance monitoring in the 
calculation of the 3-day, 24-hour rolling average emission rates using 
the equation in Sec. 63.1510(t). A performance test is required for:
    (1) Each group 1 furnace processing only clean charge to measure 
emissions of PM and either:
    (i) Emissions of HCl (for the emission limit); or
    (ii) The mass flow rate of HCl at the inlet to and outlet from the 
control device (for the percent reduction standard).
    (2) Each group 1 furnace that processes scrap other than clean 
charge to measure emissions of PM and D/F and either:
    (i) Emissions of HCl (for the emission limit); or
    (ii) The mass flow rate of HCl at the inlet to and outlet from the 
control device (for the percent reduction standard).
    (3) Each in-line fluxer to measure emissions of PM and HCl.
    (k) Feed/charge weight measurement. During the emission test(s) 
conducted to determine compliance with emission limits in a kg/Mg (lb/
ton) format, the owner or operator of an affected source or emission 
unit, subject to an emission limit in a kg/Mg (lb/ton) of feed/charge 
format, must measure (or otherwise determine) and record the total 
weight of feed/charge to the affected source or emission unit for each 
of the three test runs and calculate and record the total weight. An

delegations), Sec. 63.13 (Addresses of State air pollution control 
agencies and EPA Regional Offices), Sec. 63.14 (Incorporations by 
reference), and Sec. 63.15 (Availability of information 
confidentiality). The following sections of part 63 apply to the extent 
specified in this subpart and Table 1: Sec. 63.6 (Compliance with 
standards and maintenance requirements), Sec. 63.9 (Notification 
requirements), and Sec. 63.10 (Recordkeeping and reporting 
requirements). Section Sec. 63.11 (Control device requirements) does 
not apply to this subpart.



Sec. 63.1542  Definitions.

    Terms used in this subpart are defined in the Act, in subpart A of 
this part, or in this section as follows:
    Bag leak detection system means a system that is capable of 
continuously monitoring relative particulate matter (dust) loadings in 
the exhaust of a baghouse in order to detect bag leaks and other upset 
conditions. A bag leak detection system includes, but is not limited to, 
an instrument that operates on triboelectric, light scattering, light 
transmittance, or other effect to continuously monitor relative 
particulate matter loadings.
    Blast furnace means any reduction furnace to which sinter is charged 
and which forms separate layers of molten slag and lead bullion.
    Building means a roofed and walled structure with limited openings 
to allow access and egress for people and vehicles.
    Charging location means the physical opening through which raw 
materials are introduced into a sinter machine, blast furnace, or dross 
furnace.
    Dross furnace means any smelting furnace to which drosses are 
charged and which chemically and physically separates lead from other 
impurities.
    Drossing and refining kettle means an open-top vessel that is 
constructed of cast iron or steel and is indirectly heated from below 
and contains molten lead for the purpose of drossing, refining, or 
alloying lead. Included are pot furnaces, receiving kettles, and holding 
kettles.
    Fugitive dust source means a stationary source of hazardous air 
pollutant emissions at a primary lead smelter resulting from the 
handling, storage, transfer, or other management of lead-bearing 
materials where the source is not associated with a specific process, 
process vent, or stack. Fugitive dust sources include roadways, storage 
piles, materials handling transfer points, and materials transport 
areas.
    Furnace area means any area of a primary lead smelter in which a 
blast furnace or dross furnace is located.
    Malfunction means any sudden, infrequent, and not reasonably 
preventable failure of air pollution control equipment, process 
equipment, or a process to operate in a normal or usual manner. Failures 
that are caused in part by poor maintenance or careless operation are 
not malfunctions.
    Materials storage and handling area means any area of a primary lead 
smelter in which lead-bearing materials (including ore concentrate, 
sinter, granulated lead, dross, slag, and flue dust) are stored or 
handled between process steps, including areas in which

[[Page 96]]

materials are stored in piles, bins, or tubs, and areas in which 
material is prepared for charging to a sinter machine or smelting 
furnace.
    Operating time means the period of time in hours that an affected 
source is in operation beginning at a startup and ending at the next 
shutdown.
    Plant operating time means the period of time in hours that either a 
sinter machine or blast furnace is in operation.
    Plant roadway means any area of a primary lead smelter that is 
subject to vehicle traffic, including traffic by fork lifts, front-end 
loaders, or vehicles carrying ore concentrates or cast lead ingots. 
Excluded from this definition are employee and visitor parking areas, 
provided they are not subject to traffic by vehicles carrying lead-
bearing materials.
    Primary lead smelter means any facility engaged in the production of 
lead metal from lead sulfide ore concentrates through the use of 
pyrometallurgical techniques.
    Process fugitive source means a source of hazardous air pollutant 
emissions at a primary lead smelter that is associated with lead 
smelting or refining but is not the primary exhaust stream and is not a 
fugitive dust source. Process fugitive sources include sinter machine 
charging locations, sinter machine discharge locations, sinter crushing 
and sizing equipment, furnace charging locations, furnace taps, drossing 
kettles, and refining kettles.
    Refining and casting area means any area of a primary lead smelter 
in which drossing or refining operations occur, or casting operations 
occur.
    Shutdown means the cessation of operation of an affected source for 
any purpose.
    Sinter machine means any device in which a lead sulfide ore 
concentrate charge is heated in the presence of air to eliminate sulfur 
contained in the charge and to agglomerate the charge into a hard porous 
mass called sinter.
    Sinter machine area means any area of a primary lead smelter where a 
sinter machine, or sinter crushing and sizing equipment is located.
    Sinter machine discharge end means the physical opening at the end 
of a sinter machine where the sinter exits the sinter machine.
    Startup means the setting in operation of an affected source for any 
purpose.
    Tapping location means the opening thru which lead and slag are 
removed from the furnace.



Sec. 63.1543  Standards for process and process fugitive sources.

    Source: 67 FR 17773, Apr. 11, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.1560  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (HAP) emitted from petroleum refineries. This subpart 
also establishes requirements to demonstrate initial and continuous 
compliance with the emission limitations and work practice standards.



Sec. 63.1561  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
petroleum refinery that is located at a major source of HAP emissions.
    (1) A petroleum refinery is an establishment engaged primarily in 
petroleum refining as defined in the Standard Industrial Classification 
(SIC) code 2911 and the North American Industry Classification (NAIC) 
code 32411, and used mainly for:
    (i) Producing transportation fuels (such as gasoline, diesel fuels, 
and jet fuels), heating fuels (such as kerosene, fuel gas distillate, 
and fuel oils), or lubricants;
    (ii) Separating petroleum; or
    (iii) Separating, cracking, reacting, or reforming an intermediate 
petroleum stream, or recovering a by-product(s) from the intermediate 
petroleum stream (e.g., sulfur recovery).
    (2) A major source of HAP is a plant site that emits or has the 
potential to emit any single HAP at a rate of 9.07 megagrams (10 tons) 
or more per year

[[Page 104]]

or any combination of HAP at a rate of 22.68 megagrams (25 tons) or more 
per year.
    (b) [Reserved]



Sec. 63.1562  What parts of my plant are covered by this subpart?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at a petroleum refinery.
    (b) The affected sources are:
    (1) The process vent or group of process vents on fluidized 
catalytic cracking units that are associated with regeneration of the 
catalyst used in the unit (i.e., the catalyst regeneration flue gas 
vent).
    (2) The process vent or group of process vents on catalytic 
reforming units (including but not limited to semi-regenerative, cyclic, 
or continuous processes) that are associated with regeneration of the 
catalyst used in the unit. This affected source includes vents that are 
used during the unit depressurization, purging, coke burn, and catalyst 
rejuvenation.
    (3) The process vent or group of process vents on Claus or other 
types of sulfur recovery plant units or the tail gas treatment units 
serving sulfur recovery plants, that are associated with sulfur 
recovery.
    (4) Each bypass line serving a new, existing, or reconstructed 
catalytic cracking unit, catalytic reforming unit, or sulfur recovery 
unit. This means each vent system that contains a bypass line (e.g., 
ductwork) that could divert an affected vent stream away from a control 
device used to comply with the requirements of this subpart.
    (c) An affected source is a new affected source if you commence 
construction of the affected source after September 11, 1998, and you 
meet the applicability criteria in Sec. 63.1561 at the time you 
commenced construction.
    (d) Any affected source is reconstructed if you meet the criteria in 
Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.
    (f) This subpart does not apply to:
    (1) A thermal catalytic cracking unit.
    (2) A sulfur recovery unit that does not recover elemental sulfur or 
where the modified reaction is carried out in a water solution which 
contains a metal ion capable of oxidizing the sulfide ion to sulfur 
(e.g., the LO-CAT II process).
    (3) A redundant sulfur recovery unit not located at a petroleum 
refinery and used by the refinery only for emergency or maintenance 
backup.
    (4) Equipment associated with bypass lines such as low leg drains, 
high point bleed, analyzer vents, open-ended valves or lines, or 
pressure relief valves needed for safety reasons.
    (5) Gaseous streams routed to a fuel gas system.

                     General Compliance Requirements



Sec. 63.1570  What are my general requirements for complying with 
this subpart?

    (a) You must be in compliance with all of the non-opacity standards 
in this subpart during the times specified in Sec. 63.6(f)(1).
    (b) You must be in compliance with the opacity and visible emission 
limits in this subpart during the times specified in Sec. 63.6(h)(1).
    (c) You must always operate and maintain your affected source, 
including air pollution control and monitoring equipment, according to 
the provisions in Sec. 63.6(e)(1)(i). During the period between the 
compliance date specified for your affected source and the date upon 
which continuous monitoring systems have been installed and validated 
and any applicable operating limits have been set, you must maintain a 
log detailing the operation and maintenance of the process and emissions 
control equipment.
    (d) You must develop and implement a written startup, shutdown, and 
malfunction plan (SSMP) according to the provisions in Sec. 63.6(e)(3).
    (e) During periods of startup, shutdown, and malfunction, you must 
operate in accordance with your SSMP.
    (f) You must report each instance in which you did not meet each 
emission limitation and each operating limit in this subpart that 
applies to you. This includes periods of startup, shutdown, and 
malfunction. You also must report each instance in which you did not 
meet the work practice standards in this subpart that apply to you. 
These instances are deviations from the emission limitations and work 
practice

[[Page 116]]

standards in this subpart. These deviations must be reported according 
to the requirements in Sec. 63.1575.
    (g) Consistent with Sec. Sec. 63.6(e) and 63.7(e)(1), deviations 
that occur during a period of startup, shutdown, or malfunction are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with the SSMP. The SSMP must require 
that good air pollution control practices are used during those periods. 
The plan must also include elements designed to minimize the frequency 
of such periods (i.e., root cause analysis). The Administrator will 
determine whether deviations that occur during a period of startup, 
shutdown, or malfunction are violations, according to the provisions in 
Sec. 63.6(e) and the contents of the SSMP.



Sec. 63.1571  How and when do I conduct a performance test or other 
initial compliance demonstration?

    (a) When must I conduct a performance test? You must conduct 
performance tests and report the results by no later than 150 days after 
the compliance date specified for your source in Sec. 63.1563 and 
according to the provisions in Sec. 63.7(a)(2). If you are required to 
do a performance evaluation or test for a semi-regenerative catalytic 
reforming unit catalyst regenerator vent, you may do them at the first 
regeneration cycle after your compliance date and report the results in 
a followup Notification of Compliance Status report due no later than 
150 days after the test.
    (1) For each emission limitation or work practice standard where 
initial compliance is not demonstrated using a performance test, opacity 
observation, or visible emission observation, you must conduct the 
initial compliance demonstration within 30 calendar days after the 
compliance date that is specified for your source in Sec. 63.1563.
    (2) For each emission limitation where the averaging period is 30 
days, the 30-day period for demonstrating initial compliance begins at 
12:00 a.m. on the compliance date that is specified for your source in 
Sec. 63.1563 and ends at 11:59 p.m., 30 calendar days after the 
compliance date that is specified for your source in Sec. 63.1563.
    (3) If you commenced construction or reconstruction between 
September 11, 1998 and April 11, 2002, you must demonstrate initial 
compliance with either the proposed emission limitation or the 
promulgated emission limitation no later than October 8, 2002 or within 
180 calendar days after startup of the source, whichever is later, 
according to Sec. 63.7(a)(2)(ix).
    (4) If you commenced construction or reconstruction between 
September 11, 1998 and April 11, 2002, and you chose to comply with the 
proposed emission limitation when demonstrating initial compliance, you 
must conduct a second compliance demonstration for the promulgated 
emission limitation by October 10, 2005, or after startup of the source, 
whichever is later, according to Sec. 63.7(a)(2)(ix).
    (b) What are the general requirements for performance test and 
performance evaluations? You must:
    (1) Conduct each performance test according to the requirements in 
Sec. 63.7(e)(1).
    (2) Except for opacity and visible emission observations, conduct 
three separate test runs for each performance test as specified in Sec. 
63.7(e)(3). Each test run must last at least 1 hour.
    (3) Conduct each performance evaluation according to the 
requirements in Sec. 63.8(e).
    (4) Not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (5) Calculate the average emission rate for the performance test by 
calculating the emission rate for each individual test run in the units 
of the applicable emission limitation using Equation 2, 5, or 8 of Sec. 
63.1564, and determining the arithmetic average of the calculated 
emission rates.
    (c) What procedures must I use for an engineering assessment? You 
may choose to use an engineering assessment to calculate the process 
vent flow rate, net heating value, TOC emission rate, and total organic 
HAP emission rate expected to yield the highest daily emission rate when 
determining the emission reduction or outlet concentration for the 
organic HAP standard for catalytic reforming units. If you use an 
engineering assessment,

[[Page 117]]

you must document all data, assumptions, and procedures to the 
satisfaction of the applicable permitting authority. An engineering 
assessment may include the approaches listed in paragraphs (c)(1) 
through (c)(4) of this section. Other engineering assessments may be 
used but are subject to review and approval by the applicable permitting 
authority.
    (1) You may use previous test results provided the tests are 
representative of current operating practices at the process unit, and 
provided EPA methods or approved alternatives were used;
    (2) You may use bench-scale or pilot-scale test data representative 
of the process under representative operating conditions;
    (3) You may use maximum flow rate, TOC emission rate, organic HAP 
emission rate, or organic HAP or TOC concentration specified or implied 
within a permit limit applicable to the process vent; or
    (4) You may use design analysis based on engineering principles, 
measurable process parameters, or physical or chemical laws or 
properties. Examples of analytical methods include, but are not limited 
to:
    (i) Use of material balances based on process stoichiometry to 
estimate maximum TOC concentrations;
    (ii) Calculation of hourly average maximum flow rate based on 
physical equipment design such as pump or blower capacities; and
    (iii) Calculation of TOC concentrations based on saturation 
conditions.
    (d) Can I adjust the process or control device measured values when 
establishing an operating limit? If you do a performance test to 
demonstrate compliance, you must base the process or control device 
operating limits for continuous parameter monitoring systems on the 
results measured during the performance test. You may adjust the values 
measured during the performance test according to the criteria in 
paragraphs (d)(1) through (3) of this section.
    (1) If you must meet the HAP metal emission limitations in Sec. 
63.1564, you elect the option in paragraph (a)(1)(iii) in Sec. 63.1564 
(Ni lb/hr), and you use continuous parameter monitoring systems, you 
must establish an operating limit for the equilibrium catalyst Ni 
concentration based on the laboratory analysis of the equilibrium 
catalyst Ni concentration from the initial performance test. Section 
63.1564(b)(2) allows you to adjust the laboratory measurements of the 
equilibrium catalyst Ni concentration to the maximum level. You must 
make this adjustment using Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.017

Where:

Ecat-Limit = Operating limit for equilibrium catalyst Ni concentration, 
mg/kg;
NiEmR1st = Average Ni emission rate calculated as the 
arithmetic average Ni emission rate using Equation 5 of this section for 
each performance test run, g Ni/hr; and
Ecatst = Average equilibrium Ni concentration from laboratory 
test results, mg/kg.

    (2) If you must meet the HAP metal emission limitations in Sec. 
63.1564, you elect the option in paragraph (a)(1)(iv) in Sec. 63.1564 
(Ni lb/1,000 lb of coke burn-off), and you use continuous parameter 
monitoring systems, you must establish an operating limit for the 
equilibrium catalyst Ni concentration based on the laboratory analysis 
of the equilibrium catalyst Ni concentration from the initial 
performance test. Section 63.1564(b)(2) allows you to adjust the 
laboratory measurements of the equilibrium catalyst Ni concentration to 
the maximum level. You must make this adjustment using Equation 2 of 
this section as follows:

[[Page 118]]

[GRAPHIC] [TIFF OMITTED] TR11AP02.018

Where:

NiEmR2st = Average Ni emission rate calculated as the 
arithmetic average Ni emission rate using Equation 8 of Sec. 63.1564 
for each performance test run, mg/kg coke burn-off.

    (3) If you choose to adjust the equilibrium catalyst Ni 
concentration to the maximum level, you can't adjust any other monitored 
operating parameter (i.e., gas flow rate, voltage, pressure drop, 
liquid-to-gas ratio).
    (4) Except as specified in paragraph (d)(3) of this section, if you 
use continuous parameter monitoring systems, you may adjust one of your 
monitored operating parameters (flow rate, voltage and secondary 
current, pressure drop, liquid-to-gas ratio) from the average of 
measured values during the performance test to the maximum value (or 
minimum value, if applicable) representative of worst-case operating 
conditions, if necessary. This adjustment of measured values may be done 
using control device design specifications, manufacturer 
recommendations, or other applicable information. You must provide 
supporting documentation and rationale in your Notification of 
Compliance Status, demonstrating to the satisfaction of your permitting 
authority, that your affected source complies with the applicable 
emission limit at the operating limit based on adjusted values.
    (e) Can I change my operating limit? You may change the established 
operating limit by meeting the requirements in paragraphs (e)(1) through 
(3) of this section.
    (1) You may change your established operating limit for a continuous 
parameter monitoring system by doing an additional performance test, a 
performance test in conjunction with an engineering assessment, or an 
engineering assessment to verify that, at the new operating limit, you 
are in compliance with the applicable emission limitation.
    (2) You must establish a revised operating limit for your continuous 
parameter monitoring system if you make any change in process or 
operating conditions that could affect control system performance or you 
change designated conditions after the last performance or compliance 
tests were done. You can establish the revised operating limit as 
described in paragraph (e)(1) of this section.
    (3) You may change your site-specific opacity operating limit or Ni 
operating limit only by doing a new performance test.

the number of hours of operation per day if operation is not continuous.
    (5) Each continuous parameter monitoring system must record the 
results of each inspection, calibration, and validation check.
    (d) You must monitor and collect data according to the requirements 
in paragraphs (d)(1) and (2) of this section.
    (1) Except for monitoring malfunctions, associated repairs, and 
required quality assurance or control activities (including as 
applicable, calibration checks and required zero and span adjustments), 
you must conduct all monitoring in continuous operation (or collect data 
at all required intervals) at all times the affected source is 
operating.
    (2) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
for purposes of this regulation, including data averages and 
calculations, for fulfilling a minimum data availability requirement, if 
applicable. You must use all the data collected during all other periods 
in assessing the operation of the control device and associated control 
system.

Sec. 63.1573  What are my monitoring alternatives?

    (a) What are the approved alternatives for measuring gas flow rate? 
(1) You may use this alternative to a continuous parameter monitoring 
system for the catalytic regenerator exhaust gas flow rate for your 
catalytic cracking unit if the unit does not introduce any other gas 
streams into the catalyst regeneration vent (i.e., complete combustion 
units with no additional combustion devices). You may also use this 
alternative to a continuous parameter monitoring system for the 
catalytic regenerator atmospheric exhaust gas flow rate for your 
catalytic reforming unit during the coke burn and rejuvenation cycles if 
the unit operates as a constant pressure system during these cycles. If 
you use this alternative, you shall use the same procedure for the

[[Page 120]]

performance test and for monitoring after the performance test. You 
shall:
    (i) Install and operate a continuous parameter monitoring system to 
measure and record the hourly average volumetric air flow rate to the 
catalytic cracking unit or catalytic reforming unit regenerator. Or, you 
may determine and record the hourly average volumetric air flow rate to 
the catalytic cracking unit or catalytic reforming unit regenerator 
using the appropriate control room instrumentation.
    (ii) Install and operate a continuous parameter monitoring system to 
measure and record the temperature of the gases entering the control 
device (or exiting the catalyst regenerator if you do not use an add-on 
control device).
    (iii) Calculate and record the hourly average actual exhaust gas 
flow rate using Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR09FE05.008


Where:
Q gas = Hourly average actual gas flow rate, acfm;
1.12 = Default correction factor to convert gas flow from dry standard 
cubic feet per minute (dscfm) to standard cubic feet per minute (scfm);
Q air = Volumetric flow rate of air to regenerator, as 
determined from the control room instrumentations, dscfm;
Q other = Volumetric flow rate of other gases entering the 
regenerator as determined from the control room instrumentations, dscfm. 
(Examples of ``other'' gases include an oxygen-enriched air stream to 
catalytic cracking unit regenerators and a nitrogen stream to catalytic 
reforming unit regenerators.);
Tempgas = Temperature of gas stream in vent measured as near 
as practical to the control device or opacity monitor, [deg]K. For wet 
scrubbers, temperature of gas prior to the wet scrubber; and
Pvent = Absolute pressure in the vent measured as near as 
practical to the control device or opacity monitor, as applicable, atm. 
When used to assess the gas flow rate in the final atmospheric vent 
stack, you can assume Pvent = 1 atm.

    (2) You may use this alternative to calculating Q r, the 
volumetric flow rate of exhaust gas for the catalytic cracking 
regenerator as required in Equation 1 of Sec. 63.1564, if you have a 
gas analyzer installed in the catalytic cracking regenerator exhaust 
vent prior to the addition of air or other gas streams. You may measure 
upstream or downstream of an electrostatic precipitator, but you shall 
measure upstream of a carbon monoxide boiler. You shall:
    (i) Install and operate a continuous parameter monitoring system to 
measure and record the hourly average volumetric air flow rate to the 
catalytic cracking unit regenerator. Or, you can determine and record 
the hourly average volumetric air flow rate to the catalytic cracking 
unit regenerator using the catalytic cracking unit control room 
instrumentation.
    (ii) Install and operate a continuous gas analyzer to measure and 
record the concentration of carbon dioxide, carbon monoxide, and oxygen 
of the catalytic cracking regenerator exhaust.
    (iii) Calculate and record the hourly average flow rate using 
Equation 2 of this section as follows:

[[Page 121]]

[GRAPHIC] [TIFF OMITTED] TR09FE05.009


Where:
Q r = Volumetric flow rate of exhaust gas from the catalyst 
regenerator before adding air or gas streams, dscm/min (dscf/min);
79 = Default concentration of nitrogen and argon in dry air, percent by 
volume (dry basis);
%Oxy = Oxygen concentration in oxygen-enriched air stream, 
percent by volume (dry basis);
Q oxy = Volumetric flow rate of oxygen-enriched air stream to 
regenerator as determined from the catalytic cracking unit control room 
instrumentations, dscm/min (dscf/min);
%CO2 = Carbon dioxide concentration in regenerator exhaust, 
percent by volume (dry basis);
CO = Carbon monoxide concentration in regenerator exhaust, percent by 
volume (dry basis); and
%O2 = Oxygen concentration in regenerator exhaust, percent by 
volume (dry basis).

    (b) What is the approved alternative for monitoring pH or alkalinity 
levels? You may use the alternative in paragraph (b)(1) or (2) of this 
section for a catalytic reforming unit.
    (1) You shall measure and record the pH of the water (or scrubbing 
liquid) exiting the wet scrubber or internal scrubbing system at least 
once an hour during coke burn-off and catalyst rejuvenation using pH 
strips as an alternative to a continuous parameter monitoring system. 
The pH strips must meet the requirements in Table 41 of this subpart.
    (2) You shall measure and record the alkalinity of the water (or 
scrubbing liquid) exiting the wet scrubber or internal scrubbing system 
at least once an hour during coke burn-off and catalyst rejuvenation 
using titration as an alternative to a continuous parameter monitoring 
system.
    (c) Can I use another type of monitoring system? You may request 
approval from your permitting authority to use an automated data 
compression system. An automated data compression system does not record 
monitored operating parameter values at a set frequency (e.g., once 
every hour) but records all values that meet set criteria for variation 
from previously recorded values. Your request must contain a description 
of the monitoring system and data recording system, including the 
criteria used to determine which monitored values are recorded and 
retained, the method for calculating daily averages, and a demonstration 
that the system meets all of the criteria in paragraphs (c)(1) through 
(5) of this section:
    (1) The system measures the operating parameter value at least once 
every hour;
    (2) The system records at least 24 values each day during periods of 
operation;
    (3) The system records the date and time when monitors are turned 
off or on;
    (4) The system recognizes unchanging data that may indicate the 
monitor is not functioning properly, alerts the operator, and records 
the incident; and
    (5) The system computes daily average values of the monitored 
operating parameter based on recorded data.
    (d) Can I monitor other process or control device operating 
parameters? You may request approval to monitor parameters other than 
those required in this subpart. You must request approval if:
    (1) You use a control device other than a thermal incinerator, 
boiler, process heater, flare, electrostatic precipitator, or wet 
scrubber;
    (2) You use a combustion control device (e.g., incinerator, flare, 
boiler or process heater with a design heat capacity of at least 44 MW, 
boiler or process heater where the vent stream is introduced into the 
flame zone), electrostatic precipitator, or scrubber but want to monitor 
a parameter other than those specified; or
    (3) You wish to use another type of continuous emission monitoring 
system that provides direct measurement

[[Page 122]]

of a pollutant (i.e., a PM or multi-metals HAP continuous emission 
monitoring system, a carbonyl sulfide/carbon disulfide continuous 
emission monitoring system, a TOC continuous emission monitoring system, 
or HCl continuous emission monitoring system).
    (e) How do I request to monitor alternative parameters? You must 
submit a request for review and approval or disapproval to the 
Administrator. The request must include the information in paragraphs 
(e)(1) through (5) of this section.
    (1) A description of each affected source and the parameter(s) to be 
monitored to determine whether the affected source will continuously 
comply with the emission limitations and an explanation of the criteria 
used to select the parameter(s).
    (2) A description of the methods and procedures that will be used to 
demonstrate that the parameter can be used to determine whether the 
affected source will continuously comply with the emission limitations 
and the schedule for this demonstration. You must certify that you will 
establish an operating limit for the monitored parameter(s) that 
represents the conditions in existence when the control device is being 
properly operated and maintained to meet the emission limitation.
    (3) The frequency and content of monitoring, recording, and 
reporting, if monitoring and recording are not continuous. You also must 
include the rationale for the proposed monitoring, recording, and 
reporting requirements.
    (4) Supporting calculations.
    (5) Averaging time for the alternative operating parameter.
    (f) How do I apply for alternative monitoring requirements if my 
catalytic cracking unit is equipped with a wet scrubber and I have 
approved alternative monitoring requirements under the new source 
performance standards for petroleum refineries?
    (1) You may request alternative monitoring requirements according to 
the procedures in this paragraph if you meet each of the conditions in 
paragraphs (f)(1)(i) through (iii) of this section:
    (i) Your fluid catalytic cracking unit regenerator vent is subject 
to the PM limit in 40 CFR 60.102(a)(1) and uses a wet scrubber for PM 
emissions control;
    (ii) You have alternative monitoring requirements for the continuous 
opacity monitoring system requirement in 40 CFR 60.105(a)(1) approved by 
the Administrator; and
    (iii) You are required by this subpart to install, operate, and 
maintain a continuous opacity monitoring system for the same catalytic 
cracking unit regenerator vent for which you have approved alternative 
monitoring requirements.
    (2) You can request approval to use an alternative monitoring method 
prior to submitting your notification of compliance status, in your 
notification of compliance status, or at any time.
    (3) You must submit a copy of the approved alternative monitoring 
requirements along with a monitoring plan that includes a description of 
the continuous monitoring system or method, including appropriate 
operating parameters that will be monitored, test results demonstrating 
compliance with the opacity limit used to establish an enforceable 
operating limit(s), and the frequency of measuring and recording to 
establish continuous compliance. If applicable, you must also include 
operation and maintenance requirements for the continuous monitoring 
system.
    (4) We will contact you within 30 days of receipt of your 
application to inform you of approval or of our intent to disapprove 
your request.

                   Notifications, Reports, and Records



Sec. 63.1574  What notifications must I submit and when?

    (a) Except as allowed in paragraphs (a)(1) through (3) of this 
section, you must submit all of the notifications in Sec. Sec. 63.6(h), 
63.7(b) and (c), 63.8(e), 63.8(f)(4), 63.8(f)(6), and 63.9(b) through 
(h) that apply to you by the dates specified.
    (1) You must submit the notification of your intention to construct 
or reconstruct according to Sec. 63.9(b)(5) unless construction or 
reconstruction had commenced and initial startup had not occurred before 
April 11, 2002. In this

[[Page 123]]

case, you must submit the notification as soon as practicable before 
startup but no later than July 10, 2002. This deadline also applies to 
the application for approval of construction or reconstruction and 
approval of construction or reconstruction based on State 
preconstruction review required in Sec. Sec. 63.5(d)(1)(i) and 
63.5(f)(2).
    (2) You must submit the notification of intent to conduct a 
performance test required in Sec. 63.7(b) at least 30 calendar days 
before the performance test is scheduled to begin (instead of 60 days).
    (3) If you are required to conduct a performance test, performance 
evaluation, design evaluation, opacity observation, visible emission 
observation, or other initial compliance demonstration, you must submit 
a notification of compliance status according to Sec. 63.9(h)(2)(ii). 
You can submit this information in an operating permit application, in 
an amendment to an operating permit application, in a separate 
submission, or in any combination. In a State with an approved operating 
permit program where delegation of authority under section 112(l) of the 
CAA has not been requested or approved, you must provide a duplicate 
notification to the applicable Regional Administrator. If the required 
information has been submitted previously, you do not have to provide a 
separate notification of compliance status. Just refer to the earlier 
submissions instead of duplicating and resubmitting the previously 
submitted information.
    (i) For each initial compliance demonstration that does not include 
a performance test, you must submit the Notification of Compliance 
Status no later than 30 calendar days following completion of the 
initial compliance demonstration.
    (ii) For each initial compliance demonstration that includes a 
performance test, you must submit the notification of compliance status, 
including the performance test results, no later than 150 calendar days 
after the compliance date specified for your affected source in Sec. 
63.1563.
    (b) As specified in Sec. 63.9(b)(2), if you startup your new 
affected source before April 11, 2002, you must submit the initial 
notification no later than August 9, 2002.
    (c) If you startup your new or reconstructed affected source on or 
after April 11, 2002, you must submit the initial notification no later 
than 120 days after you become subject to this subpart.
    (d) You also must include the information in Table 42 of this 
subpart in your notification of compliance status.
    (e) If you request an extension of compliance for an existing 
catalytic cracking unit as allowed in Sec. 63.1563(c), you must submit 
a notification to your permitting authority containing the required 
information by October 13, 2003.
    (f) As required by this subpart, you must prepare and implement an 
operation, maintenance, and monitoring plan for each control system and 
continuous monitoring system for each affected source. The purpose of 
this plan is to detail the operation, maintenance, and monitoring 
procedures you will follow.
    (1) You must submit the plan to your permitting authority for review 
and approval along with your notification of compliance status. While 
you do not have to include the entire plan in your part 70 or 71 permit, 
you must include the duty to prepare and implement the plan as an 
applicable requirement in your part 70 or 71 operating permit. You must 
submit any changes to your permitting authority for review and approval 
and comply with the plan until the change is approved.
    (2) Each plan must include, at a minimum, the information specified 
in paragraphs (f)(2)(i) through (xii) of this section.
    (i) Process and control device parameters to be monitored for each 
affected source, along with established operating limits.
    (ii) Procedures for monitoring emissions and process and control 
device operating parameters for each affected source.
    (iii) Procedures that you will use to determine the coke burn-rate, 
the volumetric flow rate (if you use process data rather than direct 
measurement), and the rate of combustion of liquid or solid fossil fuels 
if you use an incinerator-waste heat boiler to burn the exhaust gases 
from a catalyst regenerator.

[[Page 124]]

    (iv) Procedures and analytical methods you will use to determine the 
equilibrium catalyst Ni concentration, the equilibrium catalyst Ni 
concentration monthly rolling average, and the hourly or hourly average 
Ni operating value.
    (v) Procedures you will use to determine the pH of the water (or 
scrubbing liquid) exiting a wet scrubber if you use pH strips.
    (vi) Procedures you will use to determine the HCl concentration of 
gases from a catalytic reforming unit when you use a colormetric tube 
sampling system, including procedures for correcting for pressure (if 
applicable to the sampling equipment) and the sampling locations that 
will be used for compliance monitoring purposes.
    (vii) Procedures you will use to determine the gas flow rate for a 
catalytic cracking unit if you use the alternative procedure based on 
air flow rate and temperature.
    (viii) Monitoring schedule, including when you will monitor and when 
you will not monitor an affected source (e.g., during the coke burn-off, 
regeneration process).
    (ix) Quality control plan for each continuous opacity monitoring 
system and continuous emission monitoring system you use to meet an 
emission limit in this subpart. This plan must include procedures you 
will use for calibrations, accuracy audits, and adjustments to the 
system needed to meet applicable requirements for the system.
    (x) Maintenance schedule for each monitoring system and control 
device for each affected source that is generally consistent with the 
manufacturer's instructions for routine and long-term maintenance.
    (xi) If you use a fixed-bed gas-solid adsorption system to control 
emissions from a catalytic reforming unit, you must implement corrective 
action procedures if the HCl concentration measured at the selected 
compliance monitoring sampling location within the bed exceeds the 
operating limit. These procedures must require, at minimum, repeat 
measurement and recording of the HCl concentration in the adsorption 
system exhaust gases and at the selected compliance monitoring sampling 
location within the bed. If the HCl concentration at the selected 
compliance monitoring location within the bed is above the operating 
limit during the repeat measurement while the HCl concentration in the 
adsorption system exhaust gases remains below the operating limit, the 
adsorption bed must be replaced as soon as practicable. Your procedures 
must specify the sampling frequency that will be used to monitor the HCl 
concentration in the adsorption system exhaust gases subsequent to the 
repeat measurement and prior to replacement of the sorbent material (but 
not less frequent than once every 4 hours during coke burn-off). If the 
HCl concentration of the adsorption system exhaust gases is above the 
operating limit when measured at any time, the adsorption bed must be 
replaced within 24 hours or before the next regeneration cycle, 
whichever is longer.
    (xii) Procedures that will be used for purging the catalyst if you 
do not use a control device to comply with the organic HAP emission 
limits for catalytic reforming units. These procedures will include, but 
are not limited to, specification of the minimum catalyst temperature 
and the minimum cumulative volume of gas per mass of catalyst used for 
purging prior to uncontrolled releases (i.e., during controlled purging 
events); the maximum purge gas temperature for uncontrolled purge 
events; and specification of the monitoring systems that will be used to 
monitor and record data during each purge event.

monitoring requirements as a result of the approved routine planned 
maintenance.
    (j) If you own or operate multiple catalytic cracking units that are 
served by a single wet scrubber emission control device (e.g., a Venturi 
scrubber), you may request the applicable permitting authority to 
approve a period of planned routine maintenance for the control device 
needed to meet requirements in your operation, maintenance, and 
monitoring plan. You must present data to the applicable permitting 
authority demonstrating that the period of planned maintenance results 
in overall emissions reductions. During this pre-approved time period, 
the emission control device may be taken out of service while 
maintenance is performed on the control device and/or one of the process 
units while the remaining process unit(s) continue to operate. During 
the period the emission control device is unable to operate, the 
emission limits, operating limits, and monitoring requirements 
applicable to the unit that is operating and the wet scrubber emission 
control device do not apply. The applicable permitting authority may 
require that you take specified actions to minimize emissions during the 
period of planned maintenance.

sulfur from gases that contain reduced sulfur compounds and other 
pollutants, usually by a vapor-phase catalytic reaction of sulfur 
dioxide and hydrogen sulfide. This definition does not include a unit 
where the modified reaction is carried out in a water solution which 
contains a metal ion capable of oxidizing the sulfide ion to sulfur, 
e.g., the LO-CAT II process.
    TOC means, for the purposes of this subpart, emissions of total 
organic compounds that serve as a surrogate measure of the total 
emissions of organic HAP compounds including, but not limited to, 
acetaldehyde, benzene, hexane, phenol, toluene, and xylenes and nonHAP 
VOC as measured by Method 25A in appendix A to part 60 of this chapter 
or by an approved alternative method.
    TRS means, for the purposes of this subpart, emissions of total 
reduced sulfur compounds, expressed as an equivalent sulfur dioxide

    1.2 Applicability. This method is applicable to the determination of 
analyte concentrations on catalyst particles. This method is applicable 
for catalyst particles obtained from the fluid catalytic cracking unit 
(FCCU) regenerator (i.e., equilibrium catalyst), from air pollution 
control systems operated for the FCCU catalyst regenerator vent (FCCU 
fines), from catalytic reforming units (CRU), and other processes as 
specified within an applicable regulation. This method is applicable 
only when specified within the regulation.
    1.3 Data Quality Objectives. Adherence to the requirements of this 
method will enhance the quality of the data obtained from the analytical 
method.

                         2.0 Summary of Method.

    2.1 A representative sample of catalyst particles is collected, 
prepared, and analyzed for analyte concentration using either energy or 
wavelength dispersive X-ray flourescent (XRF) spectrometry instrumental 
analyzers. In both types of XRF spectrometers, the instrument irradiates 
the sample with high energy (primary) x-rays and the elements in the 
sample absorb the x-rays and then re-emit secondary (fluorescent) x-rays 
of characteristic wavelengths for each element present. In energy 
dispersive XRF spectrometers, all secondary x-rays (of all wavelengths) 
enter the detector at once. The detector registers an electric current 
having a height proportional to the photon energy, and these pulses are 
then separated electronically, using a pulse analyzer. In wavelength 
dispersive XRF spectrometers, the secondary x-rays are dispersed 
spatially by crystal diffraction on the basis of wavelength. The crystal 
and detector are made to synchronously rotate and the detector then 
receives only one wavelength at a time. The intensity of the x-rays 
emitted by each element is proportional to its concentration, after 
correcting for matrix effects. For nickel compounds and total chlorides, 
the XRF instrument response is expected to be linear to analyte 
concentration. Performance specifications and test procedures are 
provided to ensure reliable data.

                            3.0 Definitions.

    3.1 Measurement System. The total equipment required for the 
determination of analyte concentration. The measurement system consists 
of the following major subsystems:
    3.1.1 Sample Preparation. That portion of a system used for one or 
more of the following: sample acquisition, sample transport, sample 
conditioning, or sample preparation prior to introducing the sample into 
the analyzer.
    3.1.2 Analyzer. That portion of the system that senses the analyte 
to be measured and generates an output proportional to its 
concentration.
    3.1.3 Data Recorder. A digital recorder or personal computer used 
for recording measurement data from the analyzer output.
    3.2 Span. The upper limit of the gas concentration measurement range 
displayed on the data recorder.
    3.3 Calibration Standards. Prepared catalyst samples or other 
samples of known analyte concentrations used to calibrate the analyzer 
and to assess calibration drift.
    3.4 Energy Calibration Standard. Calibration standard, generally 
provided by the XRF instrument manufacturer, used for assuring accuracy 
of the energy scale.
    3.5 Accuracy Assessment Standard. Prepared catalyst sample or other 
sample of known analyte concentrations used to assess analyzer accuracy 
error.
    3.6 Zero Drift. The difference in the measurement system output 
reading from the initial value for zero concentration level calibration 
standard after a stated period of operation during which no unscheduled 
maintenance, repair, or adjustment took place.
    3.7 Calibration Drift. The difference in the measurement system 
output reading from the initial value for the mid-range calibration 
standard after a stated period of operation during which no unscheduled 
maintenance, repair, or adjustment took place.
    3.8 Spectral Interferences. Analytical interferences and excessive 
biases caused by elemental peak overlap, escape peak, and sum peak 
interferences between elements in the samples.
    3.9 Calibration Curve. A graph or other systematic method of 
establishing the relationship between the analyzer response and the 
actual analyte concentration introduced to the analyzer.
    3.10 Analyzer Accuracy Error. The difference in the measurement 
system output reading and the ideal value for the accuracy assessment 
standard.

                           4.0 Interferences.

    4.1 Spectral interferences with analyte line intensity determination 
are accounted for within the method program. No action is required by 
the XRF operator once these interferences have been addressed within the 
method.
    4.2 The X-ray production efficiency is affected by particle size for 
the very lightest elements. However, particulate matter (PM) 2.5 
particle size effects are substantially < 1 percent for most elements. 
The calibration standards should be prepared with material of similar 
particle size or be processed (ground) to produce material of similar 
particle size as the catalyst samples to be analyzed. No additional 
correction for particle size is performed. Alternatively, the sample can 
be fused in order to eliminate any potential particle size effects.

                               5.0 Safety.

    5.1 Disclaimer. This method may involve hazardous materials, 
operations, and equipment. This test method may not address all of the 
safety problems associated with its use. It is the responsibility of the 
user of this test method to establish appropriate safety and health 
practices and determine the applicability of regulatory limitations 
prior to performing this test method.
    5.2 X-ray Exposure. The XRF uses X-rays; XRF operators should follow 
instrument manufacturer's guidelines to protect from accidental exposure 
to X-rays when the instrument is in operation.
    5.3 Beryllium Window. In most XRF units, a beryllium (Be) window is 
present to separate the sample chamber from the X-ray tube and detector. 
The window is very fragile and brittle. Do not allow sample or debris to 
fall onto the window, and avoid using compressed air to clean the window 
because it will cause the window to rupture. If the window should 
rupture, note that Be metal is poisonous. Use extreme caution when 
collecting pieces of Be and consult the instrument manufacturer for 
advice on cleanup of the broken window and replacement.

                       6.0 Equipment and Supplies.

    6.1 Measurement System. Use any measurement system that meets the 
specifications of this method listed in section 13. The typical 
components of the measurement system are described below.
    6.1.1 Sample Mixer/Mill. Stainless steel, or equivalent to grind/mix 
catalyst and binders, if used, to produce uniform particle samples.
    6.1.2 Sample Press/Fluxer. Stainless steel, or equivalent to produce 
pellets of sufficient size to fill analyzer sample window, or 
alternatively, a fusion device capable of preparing a fused disk of 
sufficient size to fill analyzer sample window.
    6.1.3 Analytical Balance. 0.0001 gram accuracy 
for weighing prepared samples (pellets).
    6.1.4 Analyzer. An XRF spectrometer to determine the analyte 
concentration in the prepared sample. The analyzer must meet the 
applicable performance specifications in section 13.
    6.1.5 Data Recorder. A digital recorder or personal computer for 
recording measurement data. The data recorder resolution (i.e., 
readability) must be 0.5 percent of span. Alternatively, a digital or 
analog meter having a resolution of 0.5 percent of span may be used to 
obtain the analyzer responses and the readings may be recorded manually.

                       7.0 Reagents and Standards.

    7.1 Calibration Standards. The calibration standards for the 
analyzer must be prepared catalyst samples or other material of similar 
particle size and matrix as the catalyst samples to be tested that have 
known concentrations of the analytes of interest. Preparation (grinding/
milling/fusion) of the calibration standards should follow the same 
processes used to prepare the catalyst samples to be tested. The 
calibration standards values must be established as the average of a 
minimum of three analyses using an approved EPA or ASTM method with 
instrument analyzer calibrations traceable to the U.S. National 
Institute of Standards and Technology (NIST), if available. The maximum 
percent deviation of the triplicate calibration standard analyses should 
agree within 10 percent of the average value for the triplicate analysis 
(see Figure 1). If the calibration analyses do not meet this criteria, 
the calibration standards must be re-analyzed. If unacceptable 
variability persists, new calibration standards must be prepared. 
Approved methods for the calibration standard analyses include, but are 
not limited to, EPA Methods 6010B, 6020, 7520, or 7521 of SW-846.\1\ Use 
a minimum of four calibration standards as specified below (see Figure 
1):
    7.1.1 High-Range Calibration Standard. Concentration equivalent to 
80 to 100 percent of the span. The concentration of the high-range 
calibration standard should exceed the maximum concentration anticipated 
in the catalyst samples.
    7.1.2 Mid-Range Calibration Standard. Concentration equivalent to 40 
to 60 percent of the span.
    7.1.3 Low-Range Calibration Standard. Concentration equivalent to 1 
to 20 percent of the span. The concentration of the low-range 
calibration standard should be selected so that it is less than either 
one-forth of the applicable concentration limit or of the lowest 
concentration anticipated in the catalyst samples.
    7.1.4 Zero Calibration Standard. Concentration of less than 0.25 
percent of the span.
    7.2 Accuracy Assessment Standard. Prepare an accuracy assessment 
standard and determine the ideal value for the accuracy assessment 
standard following the same procedures used to prepare and analyze the 
calibration standards as described in section 7.1. The maximum percent 
deviation of the triplicate accuracy assessment standard analyses should 
agree within 10 percent of the average value for the triplicate analysis 
(see Figure 1). The concentration equivalent of the accuracy assessment 
standard must be between 20 and 80 percent of the span.
    7.3 Energy Calibration Standard. Generally, the energy calibration 
standard will be provided by the XRF instrument manufacturer for energy 
dispersive spectrometers. Energy calibration is performed using the 
manufacturer's recommended calibration standard and involves measurement 
of a specific energy line (based on the metal in the

[[Page 178]]

energy calibration standard). This is generally an automated procedure 
used to assure the accuracy of the energy scale. This calibration 
standard may not be applicable to all models of XRF spectrometers 
(particularly wavelength dispersive XRF spectrometers).

 8.0 Sample Collection, Preservation, Transport, and Storage. [Reserved]

                          9.0 Quality Control.

    9.1 Energy Calibration. For energy dispersive spectrometers, conduct 
the energy calibration by analyzing the energy calibration standard 
provided by the manufacturer. The energy calibration involves 
measurement of a specific energy line (based on the metal in the energy 
calibration standard) and then determination of the difference between 
the measured peak energy value and the ideal value. This analysis, if 
applicable, should be performed daily prior to any sample analyses to 
check the instrument's energy scale. This is generally an automated 
procedure and assures the accuracy of the energy scale. If the energy 
scale calibration process is not automated, follow the manufacturer's 
procedures to manually adjust the instrument, as necessary.
    9.2 Zero Drift Test. Conduct the zero drift test by analyzing the 
analyte concentration output by the measurement system with the initial 
calibration value for the zero calibration standard (see Figure 2). This 
analysis should be performed with each set of samples analyzed.
    9.3 Calibration Drift Test. Conduct the calibration drift test by 
analyzing the analyte concentration output by the measurement system 
with the initial calibration value for the mid-range calibration 
standard (see Figure 2). This analysis should be performed with each set 
of samples analyzed.
    9.4 Analyzer Accuracy Test. Conduct the analyzer accuracy test by 
analyzing the accuracy assessment standard and comparing the value 
output by the measurement system with the ideal value for the accuracy 
assessment standard (see Figure 2). This analysis should be performed 
with each set of samples analyzed.

                  10.0 Calibration and Standardization.

    10.1 Perform the initial calibration and set-up following the 
instrument manufacturer's instructions. These procedures should include, 
at a minimum, the major steps listed in sections 10.2 and 10.3. 
Subsequent calibrations are to be performed when either a quality 
assurance/quality control (QA/QC) limit listed in section 13 is exceeded 
or when there is a change in the excitation conditions, such as a change 
in the tube, detector, X-ray filters, or signal processor. Calibrations 
are typically valid for 6 months to 1 year.
    10.2 Instrument Calibration. Calibration is performed initially with 
calibration standards of similar matrix and binders, if used, as the 
samples to be analyzed (see Figure 1).
    10.3 Reference Peak Spectra. Acquisition of reference spectra is 
required only during the initial calibration. As long as no processing 
methods have changed, these peak shape references remain valid. This 
procedure consists of placing the standards in the instrument and 
acquiring individual elemental spectra that are stored in the method 
file with each of the analytical conditions. These reference spectra are 
used in the standard deconvolution of the unknown spectra.

                       11.0 Analytical Procedure.

    11.1 Sample Preparation. Prepare catalyst samples using the same 
procedure used to prepare the calibration standards. Measure and record 
the weight of sample used. Measure and record the amount of binder, if 
any, used. Pellets or films must be of sufficient size to cover the 
analyzer sample window.
    11.2 Sample Analyses. Place the prepared catalyst samples into the 
analyzer. Follow the manufacturer's instructions for analyzing the 
samples.
    11.3 Record and Store Data. Use a digital recorder or personal 
computer to record and store results for each sample. Record any 
mechanical or software problems encountered during the analysis.

                  12.0 Data Analysis and Calculations.

    Carry out the following calculations, retaining at least one extra 
significant figure beyond that of the acquired data. Round off figures 
after final calculation.
    12.1 Drift. Calculate the zero and calibration drift for the tests 
described in sections 9.2 and 9.3 (see also Figure 2) as follows:

[GRAPHIC] [TIFF OMITTED] TR09FE05.010

Where:
CurrentAnalyzerCal.Response = Instrument response for current QC sample 
          analyses;

[[Page 179]]

InitialCal.Response = Initial instrument response for calibration 
          standard;
QC Value = QC metric (zero drift or calibration drift), percent of span;
Span = Span of the monitoring system.

    12.2 Analyzer Accuracy. Calculate the analyzer accuracy error for 
the tests described in section 9.4 (see also Figure 2) as follows:
[GRAPHIC] [TIFF OMITTED] TR09FE05.011


Where:
    Accuracy Value = Percent difference of instrument response to the 
ideal response for the accuracy assessment standard;
CurrentAnalyzerCal.Response = Instrument response for current QC sample 
          analyses;
IdealCal.Response = Ideal instrument response for the accuracy 
          assessment standard.

                        13.0 Method Performance.

    13.1 Analytical Range. The analytical range is determined by the 
instrument design. For this method, a portion of the analytical range is 
selected by choosing the span of the monitoring system. The span of the 
monitoring system must be selected such that it encompasses the range of 
concentrations anticipated to occur in the catalyst sample. If 
applicable, the span must be selected such that the analyte 
concentration equivalent to the emission standard is not less than 30 
percent of the span. If the measured analyte concentration exceeds the 
concentration of the high-range calibration standard, the sample 
analysis is considered invalid. Additionally, if the measured analyte 
concentration is less than the concentration of the low-range 
calibration standard but above the detectable limit, the sample analysis 
results must be flagged with a footnote stating, in effect, that the 
analyte was detected but that the reported concentration is below the 
lower quantitation limit.
    13.2 Minimum Detectable Limit. The minimum detectable limit depends 
on the signal-to-noise ratio of the measurement system. For a well-
designed system, the minimum detectable limit should be less than 2 
percent of the span.
    13.3 Zero Drift. Less than 2 percent of the 
span.
    13.4 Calibration Drift. Less than 5 percent of 
the span.
    13.5 Analyzer Accuracy Error. Less than 10 
percent.

 Subpart VVV_National Emission Standards for Hazardous Air Pollutants: 
                     Publicly Owned Treatment Works

    Source: 64 FR 57579, Oct. 26, 1999, unless otherwise noted.

                              Applicability



Sec. 63.1580  Am I subject to this subpart?

    (a) You are subject to this subpart if the following are all true:
    (1) You own or operate a publicly owned treatment works (POTW) that 
includes an affected source (Sec. 63.1595);
    (2) The affected source is located at a POTW which is a major source 
of HAP emissions, or at any industrial POTW regardless of whether or not 
it is a major source of HAP; and
    (3) Your POTW is required to develop and implement a pretreatment 
program as defined by 40 CFR 403.8 (for a POTW owned or operated by a 
municipality, State, or intermunicipal or interstate agency), or your 
POTW would meet the general criteria for development and implementation 
of a pretreatment program (for a POTW owned or operated by a department, 
agency, or instrumentality of the Federal government).
    (b) If your existing POTW treatment plant is not located at a major 
source as of October 26, 1999, but thereafter becomes a major source for 
any reason other than reconstruction, then, for the purpose of this 
subpart, your POTW treatment plant would be considered an existing 
source. Note to Paragraph (b): See Sec. 63.2 of the national emission 
standards for hazardous air pollutants (NESHAP) General Provisions in 
subpart A of this part for the definitions of major source and area 
source.
    (c) If you reconstruct your POTW treatment plant, then the 
requirements for a new or reconstructed POTW treatment plant, as defined 
in Sec. 63.1595, apply.

[67 FR 64745, Oct. 21, 2002]



Sec. 63.1581  Does the subpart distinguish between different types of 
POTW treatment plants?

    Yes, POTW treatment plants are divided into two subcategories. A 
POTW treatment plant which does not meet the characteristics of an 
industrial POTW treatment plant belongs in the non-industrial POTW 
treatment plant subcategory as defined in Sec. 63.1595.

      Industrial POTW Treatment Plant Description and Requirements



Sec. 63.1582  What are the characteristics of an industrial POTW 
treatment plant?

    (a) Your POTW is an industrial POTW treatment plant if an industrial 
discharger complies with its NESHAP by using the treatment and controls 
located at your POTW. Your POTW accepts the regulated waste stream and 
provides treatment and controls as an agent for the industrial 
discharger. Industrial POTW treatment plant is defined in Sec. 63.1595.
    (b) If, in the future, an industrial discharger begins complying 
with its NESHAP by using the treatment and controls at your POTW, then 
on the date that the industrial discharger certifies compliance, your 
POTW treatment plant will be considered an industrial POTW treatment 
plant.

[[Page 181]]

    (c) If your POTW treatment plant accepts one or more specific 
regulated industrial waste streams as part of compliance with one or 
more other NESHAP, then you are subject to all the requirements of each 
appropriate NESHAP for each waste stream, as described in the following 
section. In the case of overlapping NESHAP requirements, the more 
stringent of the requirements will apply.



Sec. 63.1583  What are the emission points and control requirements for 
an industrial POTW treatment plant?

    (a) The emission points and control requirements for an existing 
industrial POTW treatment plant are specified in the appropriate 
NESHAP(s) for the industrial user(s) (see Sec. 63.1582). For example, 
an existing industrial POTW treatment plant that provides treatment for 
a facility subject to subpart FF of this part, the National Emission 
Standard for Benzene Waste Operations, must meet the treatment and 
control requirements specified in Sec. 61.348(d)(4) of this chapter.
    (b) The emission points and control requirements for a new or 
reconstructed industrial POTW treatment plant are either those specified 
by the particular NESHAP(s) which apply to the industrial user(s) who 
discharge their waste for treatment to the POTW, or those emission 
points and control requirements set forth in Sec. 63.1586. The set of 
control requirements which applies to a particular new or reconstructed 
POTW is that set which requires the most stringent overall control of 
HAP emissions. If you are uncertain which set of requirements is more 
stringent, this determination should be made in consultation with the 
permitting authority. Reconstruction is defined in Sec. 63.1595.



Sec. 63.1584  When do I have to comply?

    (a) Existing industrial POTW treatment plant. If you have an 
existing industrial POTW treatment plant, the appropriate NESHAP(s) for 
the industrial user(s) sets the compliance date, or the compliance date 
is 60 days after October 26, 1999, whichever is later.
    (b) New industrial POTW treatment plant. If you have a new 
industrial POTW treatment plant, you must be in compliance as soon as 
you begin accepting the waste stream(s) for treatment. If you begin 
accepting a specific regulated industrial waste stream(s) for treatment, 
you must be in compliance by the time specified in the appropriate 
NESHAP(s) for the industrial user(s).



Sec. 63.1585  How does an industrial POTW treatment plant demonstrate 
compliance?

    (a) An existing industrial POTW treatment plant demonstrates 
compliance by operating treatment and control devices which meet all 
requirements specified in the appropriate industrial NESHAP(s). 
Requirements may include performance tests, routine monitoring, 
recordkeeping, and reporting.
    (b) If you have a new or reconstructed industrial POTW plant, you 
must first determine whether the control requirements set forth in the 
applicable industrial NESHAP(s) or the control requirements applicable 
to a new or reconstructed nonindustrial POTW under Sec. 63.1586 would 
require more stringent overall control of HAP emissions. You must then 
meet whichever set of requirements is more stringent. If you determine 
that the controls required by the applicable industrial NESHAP(s) are 
more stringent, you demonstrate compliance by operating treatment and 
control devices which meet all requirements specified in those 
industrial NESHAP(s). If you determine that the controls required for a 
new or reconstructed nonindustrial POTW are more stringent, you 
demonstrate compliance by meeting all requirements in Sec. Sec. 63.1586 
through 63.1590.

            Non-industrial POTW Treatment Plant Requirements



Sec. 63.1586  What are the emission points and control requirements 
for a non-industrial POTW treatment plant?

    There are no control requirements for an existing non-industrial 
POTW treatment plant. There are no control requirements for any new or 
reconstructed area source non-industrial POTW treatment plant which is 
not a major source of HAP. The control requirements for a new or 
reconstructed

[[Page 182]]

major source non-industrial POTW treatment plant which is a major source 
of HAP are as follows:
    (a) Covers on the emission points up to, but not including, the 
secondary influent pumping station or the secondary treatment units. 
These emission points are treatment units that include, but are not 
limited to, influent waste stream conveyance channels, bar screens, grit 
chambers, grinders, pump stations, aerated feeder channels, primary 
clarifiers, primary effluent channels, and primary screening stations. 
In addition, all covered units, except primary clarifiers, must have the 
air in the headspace ducted to a control device in accordance with the 
standards for closed-vent systems and control devices in Sec. 63.693 of 
subpart DD of this part, except you may substitute visual inspections 
for leak checks rather than Method 21 of Appendix A of part 60 of this 
chapter. Reconstruction is defined in Sec. 63.1595.
    (1) Covers must be tightly fitted and designed and operated to 
minimize exposure of the wastewater to the atmosphere. This includes, 
but is not limited to, the absence of visible cracks, holes, or gaps in 
the roof sections or between the roof and the supporting wall; broken, 
cracked, or otherwise damaged seals or gaskets on closure devices; and 
broken or missing hatches, access covers, caps, or other closure 
devices.
    (2) If wastewater is in a treatment unit, each opening must be 
maintained in a closed, sealed position, unless plant personnel are 
present and conducting wastewater or sludge sampling, or equipment 
inspection, maintenance, or repair.
    (b) As an alternative to the requirements in paragraph (a) of this 
section, you may comply by demonstrating, for all units up to the 
secondary influent pumping station or the secondary treatment units, 
that the fraction emitted does not exceed 0.014. You must demonstrate 
that for your POTW, the sum of all HAP emissions from those units 
divided by the sum of all HAP mass loadings results in a annual rolling 
average of the fraction emitted no greater than 0.014. You may use any 
combination of pretreatment, wastewater treatment plant modifications, 
and control devices to achieve this performance standard; however, you 
must demonstrate, to the Administrator's satisfaction that:
    (1) You have accurately determined your POTW's annual HAP mass 
loadings and your POTW's annual HAP emissions as of the date of start-
up;
    (2) Your POTW meets the fraction emitted standard of 0.014 or less; 
and
    (3) Your POTW has established procedures to demonstrate continuous 
compliance which are consistent with the criteria set forth in Sec. 
63.1588(c)(4).

[64 FR 57579, Oct. 26, 1999, as amended at 66 FR 16142, Mar. 23, 2001; 
67 FR 64746, Oct. 21, 2002]



Sec. 63.1587  When do I have to comply?

    If your POTW treatment plant began construction on or after December 
1, 1998, you must comply with all provisions of this subpart either 
immediately upon startup, or by six months after October 26, 1999, 
whichever date is later.



Sec. 63.1588  What inspections must I conduct?

    (a) If your treatment units are required to have covers, you must 
conduct the following inspections:
    (1) You must visually check the cover and its closure devices for 
defects that could result in air emissions. Defects include, but are not 
limited to, visible cracks, holes, or gaps in the roof sections or 
between the roof and the supporting wall; broken, cracked, or otherwise 
damaged seals or gaskets on closure devices; and broken or missing 
hatches, access covers, caps, or other closure devices.
    (2) You must perform an initial visual inspection with follow-up 
inspections at least once per year.
    (3) In the event that you find a defect on a treatment unit in use, 
you must repair the defect within 45 days. If you cannot repair within 
45 days, you must notify the EPA or the designated State authority 
immediately and report the reason for the delay and the date you expect 
to complete the repair. If you find a defect on a treatment unit that is 
not in service, you must repair the defect prior to putting the 
treatment unit back in wastewater service.
    (b) If you own or operate a control device used to meet the 
requirements

[[Page 183]]

for Sec. 63.1586, you must comply with the inspection and monitoring 
requirements of Sec. 63.695(c) of subpart DD of this part.
    (c) To comply with the performance standard specified in Sec. 
63.1586(b), you must develop an inspection and monitoring plan. This 
inspection and monitoring plan must include, at a minimum, the 
following:
    (1) A method to determine, to the satisfaction of the Administrator, 
the influent HAP mass loading, i.e., the annual mass quantity for each 
HAP entering the wastewater treatment plant.
    (2) A method to determine, to the satisfaction of the Administrator, 
your POTW's annual HAP emissions for all units up to and including the 
secondary influent pumping station or up to and not including the 
secondary treatment units as of October 26, 1999. The method you use to 
determine your HAP emissions, such as modeling or direct source 
measurement, must:
    (i) Be approved by your EPA Regional Office, State, or local 
regulatory agency for use at your POTW;
    (ii) Account for all factors affecting emissions from your plant 
including, but not limited to, emissions from wastewater treatment 
units; emissions resulting from inspection, maintenance, and repair 
activities; fluctuations (e.g., daily, monthly, annual, seasonal) in 
your influent wastewater HAP concentrations; annual industrial loading; 
performance of control devices; or any other factors that could affect 
your annual HAP emissions; and
    (iii) Include documentation that the values and sources of all data, 
operating conditions, assumptions, etc., used in your method result in 
an accurate estimation of annual emissions from your plant.
    (3) Documentation, to the satisfaction of the Administrator, that 
your POTW meets the fraction emitted standard of 0.014 or less, i.e., 
the sum of all HAP emissions from paragraph (c)(2) of this section 
divided by the sum of all HAP mass loadings from paragraph (c)(1) of 
this section results in a fraction emitted of 0.014 or less as described 
in paragraph (c)(4) of this section.
    (4) A method to demonstrate, to the satisfaction of the 
Administrator, that your POTW is in continuous compliance with the 
requirements of Sec. 63.1586(b). Continuous compliance means that your 
emissions, when averaged over the course of a year, do not exceed the 
level of emissions that allows your POTW to comply with Sec. 
63.1586(b). For example, you may identify a parameter(s) that you can 
monitor that assures your emissions, when averaged over the entire year, 
will meet the requirements in Sec. 63.1586(b). Some example parameters 
that may be considered for monitoring include your wastewater influent 
HAP concentration and flow, industrial loading from your permitted 
industrial dischargers, and your control device performance criteria. 
Where emission reductions are due to proper operation of equipment, work 
practices, or other operational procedures, your demonstration must 
specify the frequency of inspections and the number of days to 
completion of repairs. You must, at a minimum, perform the following 
each month to demonstrate that your annual rolling average of the 
fraction emitted is 0.014 or less:
    (i) Determine the average daily flow of the wastewater entering your 
POTW treatment plant for the month;
    (ii) Determine the flow-weighted monthly concentration of each HAP 
in your influent listed in Table 1 to subpart DD of this part;
    (iii) Using the current month's information in paragraphs (c)(4)(i) 
and (ii) of this section, determine a total annual loading (Mg/year) of 
each HAP entering your POTW treatment plant;
    (iv) Sum up the values in paragraph (c)(4)(iii) of this section and 
determine a total annual loading value (Mg/year) for all HAP entering 
your POTW treatment plant for the current month;
    (v) Based on the current month's information in paragraph 
(c)(4)(iii) of this section along with source testing and emission 
modeling, for each HAP, determine annual emissions (Mg/year) from all 
wastewater units up to, but not including, secondary treatment units;
    (vi) Sum up the values in paragraph (c)(4)(v) of this section and 
determine the total annual emissions value for

[[Page 184]]

the month for all HAP from all wastewater units up to, but not 
including, secondary treatment units;
    (vii) Calculate the fraction emitted value for the month by dividing 
the total annual HAP emissions value from paragraph (c)(4)(vi) of this 
section by the total annual loading from paragraph (c)(4)(iv) of this 
section; and
    (viii) Average the fraction emitted value for the month determined 
in paragraph (c)(4)(vii) of this section, with the values determined for 
the previous 11 months, to calculate an annual rolling average of the 
fraction HAP emitted.



Sec. 63.1589  What records must I keep?

    (a) To comply with the equipment standard specified in Sec. 
63.1586(a), you must prepare and maintain the records required in 
paragraphs (a)(1) through (4) of this section:
    (1) A record for each treatment unit inspection required by Sec. 
63.1588(a). You must include a treatment unit identification number (or 
other unique identification description as selected by you) and the date 
of inspection.
    (2) For each defect detected during inspections required by Sec. 
63.1588(a), you must record the location of the defect, a description of 
the defect, the date of detection, the corrective action taken to repair 
the defect, and the date the repair to correct the defect is completed.
    (3) In the event that repair of the defect is delayed, in accordance 
with the provisions of Sec. 63.1588(a)(3), you must also record the 
reason for the delay and the date you expect to complete the repair.
    (4) If you own or operate a control device used to meet the 
requirements for Sec. 63.1586, you must comply with the recordkeeping 
requirements of Sec. 63.696(a), (b), (g), and (h).
    (b) To comply with the performance standard specified in Sec. 
63.1586(b), you must prepare and maintain the records required in 
paragraphs (b)(1) through (3) of this section:
    (1) A record of the methods and data used to determine your POTW's 
annual HAP emissions as determined in Sec. 63.1588(c)(2);
    (2) A record of the methods and data used to determine that your 
POTW meets the fraction emitted standard of 0.014 or less, as determined 
in Sec. 63.1588(c)(3); and
    (3) A record of the methods and data that demonstrates that your 
POTW is in continuous compliance with the requirements of Sec. 
63.1588(c)(4).

Sec. 63.1590  What reports must I submit?

    (a)(1) If you have an existing non-industrial POTW treatment plant, 
or a new or reconstructed area source non-industrial POTW treatment 
plant, you are not required to submit a notification of compliance 
status. If you have a new or reconstructed non-industrial POTW treatment 
plant which is a major source of HAP, you must submit to the 
Administrator a notification of compliance status, signed by the 
responsible official who must certify its accuracy, attesting to whether 
your POTW treatment plant has complied with this subpart. This 
notification must be submitted initially, and each time a notification 
of compliance status is required under this subpart. At a minimum, the 
notification must list--
    (i) The methods that were used to determine compliance;
    (ii) The results of any monitoring procedures or methods that were 
conducted;
    (iii) The methods that will be used for determining continuing 
compliance;
    (iv) The type and quantity of HAP emitted by your POTW treatment 
plant;
    (v) A description of the air pollution control equipment (or method) 
for each emission point; and
    (vi) Your statement that your POTW treatment plant has complied with 
this subpart.
    (2) You must send this notification before the close of business on 
the 60th day following the completion of the relevant compliance 
demonstration activity specified in this subpart.
    (b) After you have been issued a title V permit, you must comply 
with all requirements for compliance status reports contained in your 
title V permit, including reports required under this subpart. After you 
have been issued a

[[Page 185]]

title V permit, and each time a notification of compliance status is 
required under this subpart, you must submit the notification of 
compliance status to the appropriate permitting authority, as described 
in paragraph (d) of this section, following completion of the relevant 
compliance demonstration activity specified in this subpart.
    (c) You must comply with the delay of repair reporting required in 
Sec. 63.1588(a)(3).
    (d) If your State has not been delegated authority, you must submit 
reports to your EPA Regional Office. If your State has been delegated 
authority, you must submit reports to your delegated State authority, 
and you must send a copy of each report submitted to the State to your 
EPA Regional Office. Your EPA Regional Office, at its discretion, may 
waive this requirement for any reports.
    (e) You may apply to the Administrator for a waiver of recordkeeping 
and reporting requirements by complying with the requirements of Sec. 
63.10(f) of subpart A of this part.
    (f) If you own or operate a control device used to meet the 
requirements of Sec. 63.1586(a), you must submit the reports required 
by Sec. 63.697(b) of subpart DD of this part, including a notification 
of performance tests; a performance test report; a startup, shutdown, 
and malfunction report; and a summary report.
    (g) To comply with the performance standard specified in Sec. 
63.1586(b), you must submit, for approval by the Administrator, an 
initial report explaining your compliance approach 90 days prior to 
beginning operation of your new or reconstructed POTW. You must also

                          General Requirements



Sec. 63.1591  What are my notification requirements?

    (a) If you have an industrial POTW treatment plant or a new or 
reconstructed non-industrial POTW which is a major source of HAP, and 
your State has not been delegated authority, you must submit 
notifications to the appropriate EPA Regional Office. If your State has 
been delegated authority you must submit notifications to your State and 
a copy of each notification to the appropriate EPA Regional Office. The 
Regional Office may waive this requirement for any notifications at its 
discretion.
    (b) You must notify the Administrator in writing no later than 120 
calendar days after the effective date of this subpart (or within 120 
calendar days after your POTW treatment plant becomes subject to the 
relevant standard), and you must provide the following information:
    (1) Your name and address;
    (2) The address (i.e., physical location) of your POTW treatment 
plant;
    (3) An identification of these standards as the basis of the 
notification and your POTW treatment plant's compliance date; and

[68 FR 37360, June 23, 2003]



Sec. 63.1595  List of definitions.

    Affected source means the group of all equipment that comprise the 
POTW treatment plant.
    Area source means any stationary source of HAP that is not a major 
source.
    Cover means a device that prevents or reduces air pollutant 
emissions to the atmosphere by forming a continuous barrier over the 
waste material managed in a treatment unit. A cover may have openings 
(such as access hatches, sampling ports, gauge wells) that are necessary 
for operation, inspection, maintenance, and repair of the treatment unit 
on which the cover is used. A cover may be a separate piece of equipment 
which can be detached and removed from the treatment unit, or a cover 
may be formed by structural features permanently integrated into the 
design of the treatment unit. The cover and its closure devices must be 
made of suitable materials that will minimize exposure of the waste 
material to the atmosphere, to the extent practical, and will maintain 
the integrity of the cover and its closure devices throughout its 
intended service life.
    Fraction emitted means the fraction of the mass of HAP entering the 
POTW wastewater treatment plant which is emitted prior to secondary 
treatment. The value is calculated using the following steps:
    (1) Determine mass emissions from all equipment up to, but not 
including, secondary treatment for each HAP listed in Table 1 to subpart 
DD of this part;
    (2) Sum the HAP emissions ([Sigma]E);
    (3) Sum the HAP mass loadings ([Sigma]L) in the influent to the POTW 
wastewater treatment plant; and
    (4) Calculate the fraction emitted (fe monthly) using 
fe monthly = [Sigma]E/[Sigma]L.
    HAP means hazardous air pollutant(s).
    Industrial POTW means a POTW that accepts a waste stream regulated 
by an industrial NESHAP and provides treatment and controls as an agent 
for the industrial discharger. The industrial discharger complies with 
its NESHAP by using the treatment and controls located at the POTW. For 
example, an industry discharges its benzene-containing waste stream to 
the POTW for treatment to comply with 40 CFR part 61, Subpart FF--
National Emission Standard for Benzene Waste Operations. This definition 
does not include POTW treating waste streams not specifically regulated 
under another NESHAP.
    Industrial user means a nondomestic source introducing any pollutant 
or combination of pollutants into a POTW. Industrial users can be 
commercial or industrial facilities whose wastes enter local sewers.
    Non-industrial POTW means a POTW that does not meet the definition 
of an industrial POTW as defined above.
    Publicly owned treatment works (POTW) means a treatment works, as 
that term is defined by section 112(e)(5) of the Clean Air Act, which is 
owned by

[[Page 187]]

a municipality (as defined by section 502(4) of the Clean Water Act), a 
State, an intermunicipal or interstate agency, or any department, 
agency, or instrumentality of the Federal Government. This definition 
includes any intercepting sewers, outfall sewers, sewage collection 
systems, pumping, power, and other equipment. The wastewater treated by 
these facilities is generated by industrial, commercial, and domestic 
sources. As used in this regulation, the term POTW refers to both any 
publicly owned treatment works which is owned by a State, municipality, 
or intermunicipal or interstate agency and therefore eligible to receive 
grant assistance under the Subchapter II of the Clean Water Act, and any 
federally owned treatment works as that term is described in section 
3023 of the Solid Waste Disposal Act.
    POTW treatment plant means that portion of the POTW which is 
designed to provide treatment (including recycling and reclamation) of 
municipal sewage and industrial waste.
    Reconstruction means the replacement of components of an affected or 
a previously unaffected stationary source such that:
    (1) The fixed capital cost of the new components exceeds 50 percent 
of the fixed capital cost that would be required to construct a 
comparable new source; and
    (2) It is technologically and economically feasible for the 
reconstructed source to meet the relevant standard(s) established by the 
Administrator (or a State) pursuant to section 112 of the Act. Upon 
reconstruction, an affected source, or a stationary source that becomes 
an affected source, is subject to relevant standards for new sources, 
including compliance dates, irrespective of any change in emissions of 
HAP from that source.
    Secondary treatment means treatment processes, typically biological, 
designed to reduce the concentrations of dissolved and colloidal organic 
matter in wastewater.
    Waste and wastewater means a material, or spent or used water or 
waste, generated from residential, industrial, commercial, mining, or 
agricultural operations or from community activities that contain 
dissolved or suspended matter, and that is discarded, discharged, or is 
being accumulated, stored, or physically, chemically, thermally, or 
biologically treated in a publicly owned treatment works.

Sec. 63.1651  Definitions.

    Terms in this subpart are defined in the Clean Air Act (Act), in 
subpart A of this part, or in this section as follows:
    Bag leak detection system means a system that is capable of 
continuously monitoring particulate matter (dust) loadings in the 
exhaust of a baghouse in order to detect bag leaks and other upset 
conditions. A bag leak detection system includes, but is not limited to, 
an instrument that operates on triboelectric, light scattering, light 
transmittance, or other effect to continuously monitor relative 
particulate matter loadings.
    Capture system means the equipment (including hoods, ducts, fans, 
dampers, etc.) used to capture or transport particulate matter generated 
by an affected submerged arc furnace.
    Casting means the period of time from when molten ferroalloy falls 
from the furnace tapping runner into the ladle until pouring into molds 
is completed. This includes the following operations: ladle filling, 
pouring alloy from one ladle to another, slag separation, slag removal, 
and ladle transfer by crane, truck, or other conveyance.
    Crushing and screening equipment means the crushers, grinders, 
mills, screens and conveying systems used to crush, size, and prepare 
for packing

[[Page 191]]

manganese-containing materials, including raw materials, intermediate 
products, and final products.

bearing particles are discharged to the atmosphere due to wind or 
mechanical inducement such as vehicle traffic. Fugitive dust sources 
include plant roadways, yard areas, and outdoor material storage and 
transfer operations.
    Furnace power input means the resistive electrical power consumption 
of a submerged arc furnace, expressed as megawatts (MW).
    Malfunction means any sudden, infrequent, and not reasonably 
preventable failure of air pollution control equipment, process 
equipment, or a process to operate in a normal or usual manner. Failures 
caused in part by poor maintenance or careless operation are not 
malfunctions.
    Metal oxygen refining (MOR) process means the reduction of the 
carbon content of ferromanganese through the use of oxygen.
    Open submerged arc furnace means an electric submerged arc furnace 
that is equipped with a canopy hood above the furnace to collect primary 
emissions.
    Operating time means the period of time in hours that the affected 
source is in operation beginning at a startup and ending at the next 
shutdown.
    Plant roadway means any area at a ferromanganese and silicomanganese 
production facility that is subject to plant mobile equipment, such as 
fork lifts, front end loaders, or trucks, carrying manganese-bearing 
materials. Excluded from this definition are employee and visitor 
parking areas, provided they are not subject to traffic by plant mobile 
equipment.
    Primary emissions means gases and emissions collected by hoods and 
ductwork located above an open furnace or under the cover of a semi-
closed or sealed furnace.
    Sealed submerged arc furnace means an electric submerged arc furnace 
equipped with a total enclosure or cover from which primary emissions 
are evacuated directly.
    Semi-closed submerged arc furnace means an electric submerged arc 
furnace equipped with a partially sealed cover over the furnace. This 
cover is equipped with openings to allow penetration of the electrodes 
into the furnace. Mix is introduced into the furnace around the 
electrode holes forming a partial seal between the electrodes and the 
cover. Furnace emissions generated under the cover are ducted to an 
emission control device. Emissions that escape the cover are collected 
and vented through stacks directly to the atmosphere.
    Shop means the building which houses one or more submerged arc 
furnaces.
    Shutdown means the cessation of operation of an affected source for 
any purpose.
    Startup means the setting in operation of an affected source for any 
purpose.

converted to heat energy by transmission of current between electrodes 
partially submerged in the furnace charge. The furnace may be of an 
open, semi-sealed, or sealed design.
    Tapping emissions means a source of air pollutant emissions that 
occur during the process of removing the molten product from the 
furnace.
    Tapping period means the time from when a tap hole is opened until

for the Administrator's inspection for the life of the air pollution 
control device or until the affected source is no longer subject to the 
provisions of this part.
    (2) To satisfy the requirement to develop maintenance plans, the 
owner or operator may use the affected source's standard operating 
procedures (SOP) manual or other plan, provided the alternative plan 
meets the requirements of this paragraph and is made available for 
inspection when requested by the Administrator.
    (c) The procedures specified in the maintenance plan must include a 
preventive maintenance schedule that is consistent with good air

pollution control devices or vent stacks subject to Sec. 63.1652(a) 
through (e) to demonstrate compliance with the applicable emission 
standards.
    (2) The owner or operator must conduct annual performance tests for 
the air pollution control devices and vent stacks associated with the 
submerged arc furnaces, with the exception of any air pollution control 
devices that serve tapping emissions combined with non-furnace 
emissions, such as the MOR process or equipment associated with crushing 
and screening. Also excluded are air pollution control devices that 
serve dedicated non-furnace emissions, such as the MOR process or 
equipment associated with crushing and screening. The results of these 
annual tests will be used to demonstrate compliance with the emission 
standards in Sec. 63.1652(a) through (e), as applicable.
    (3) Following development, and approval, if required, of the site-
specific test plan, the owner or operator must conduct a performance 
test for each air pollution control device or vent stack to measure 
particulate matter and determine compliance with the applicable 
standard.
    (i) An owner or operator of sources subject to the particulate 
matter concentration standards in Sec. 63.1652(a)(2), (d), or (e), must 
determine compliance as follows:
    (A) Determine the particulate matter concentration using Method 5 or 
5D, as applicable.
    (B) Compliance is demonstrated if the average concentration for the 
three runs comprising the performance test does not exceed the standard.
    (ii) An owner or operator of sources subject to the particulate mass 
rate standards in Sec. 63.1652(b) or (c) must determine compliance as 
follows:

flow rate using Method 5 or 5D, as applicable.
    (B) Compute the mass rate (EM) of particulate matter for 
each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR20MY99.000

Where:

EM = mass rate of particulate matter, kg/hr (lb/hr).
N = total number of exhaust streams at which emissions are quantified.
Csi = concentration of particulate matter from exhaust stream 
``i'', mg/dscm (gr/dscf).
Qsdi = volumetric flow rate of effluent gas from exhaust 
stream ``i'', dscm/hr (dscf/hr)
K = conversion factor, 1 x 106 mg/kg (7,000 gr/lb).

    (C) Compliance is demonstrated if the average of the mass rates for 
the three runs comprising the performance test does not exceed the 
standard.
    (iii) An owner or operator of sources subject to the particulate 
matter process-weighted rate standard in Sec. 63.1652(a)(1) must 
determine compliance as follows:
    (A) Determine particulate matter concentration and volumetric flow 
rate using Method 5 or 5D, as applicable.
    (B) Compute the process-weighted mass rate (EP) of 
particulate matter for each run using the following equation:
[GRAPHIC] [TIFF OMITTED] TR20MY99.001

Where:

EP = process-weighted mass rate of particulate matter, kg/hr/
MW (lb/hr/MW).
N = total number of exhaust streams at which emissions are quantified.
Csi = concentration of particulate matter from exhaust stream 
``i'', mg/dscm (gr/dscf)
Qsdi = volumetric flow rate of effluent gas from exhaust 
stream ``i'', dscm/hr (dscf/hr)
P = Average furnace power input, MW
K = conversion factor, 1 x 106 mg/kg (7,000 gr/lb).

    (C) Compliance is demonstrated if the average process-weighted mass 
rate for the three runs comprising the performance test does not exceed 
the standard.
    (4) If a venturi scrubber is used to comply with the emission 
standards, the owner or operator must establish as a site-specific 
operating parameter the lowest average pressure drop on

[[Page 195]]

any individual complying run in the three runs constituting any 
compliant test. The pressure drop must be monitored at least every 5 
minutes during the test and hourly averages recorded.
    (i) [Reserved]
    (ii) The owner or operator may augment the data obtained under 
paragraph (a)(4) of this section by conducting multiple performance 
tests to establish a range of compliant operating parameter values. The 
lowest value of this range would be selected as the operating parameter 
monitoring value. The use of historic compliance data may be used to 
establish the compliant operating parameter value if the previous values 
were recorded during performance tests using the same test methods 
specified in this subpart and established as required in paragraph 
(a)(4) of this section.
    (d) Compliance demonstration with opacity standards. (1)(i) The 
owner or operator subject to Sec. 63.1653 must conduct initial opacity 
observations of the shop building to demonstrate compliance with the 
applicable opacity standards according to Sec. 63.6(h)(5), which 
addresses the conduct of opacity or visible emission observations.
    (ii) In conducting the opacity observations of the shop building, 
the observer must limit his or her field of view to the area of the shop 
building roof monitor that corresponds to the placement of the affected 
submerged arc furnaces.
    (iii) The owner or operator must conduct the opacity observations 
according to EPA Method 9 of 40 CFR part 60, appendix A, for a minimum 
of 60 minutes.
    (2)(i) When demonstrating initial compliance with the shop building 
opacity standard, as required by paragraph (d)(1) of this section, the 
owner or operator must simultaneously establish parameter values for one 
of the following: the control system fan motor amperes and all capture 
system damper positions, the total volumetric flow rate to the air 
pollution control device and all capture system damper positions, or 
volumetric flow rate through each separately ducted hood that comprises 
the capture system.
    (ii) The owner or operator may petition the Administrator to 
reestablish these parameters whenever he or she can demonstrate to the 
Administrator's satisfaction that the submerged arc furnace operating 
conditions upon which the parameters were previously established are no 
longer applicable. The values of these parameters determined during the 
most recent demonstration of compliance must be maintained at the 
appropriate level for each applicable period.
    (3) The owner or operator must demonstrate continuing compliance 
with the opacity standards by following the monitoring requirements 
specified in Sec. 63.1657(c) and the reporting and recordkeeping 
requirements specified in Sec. Sec. 63.1659(b)(4) and 63.1660(b).
    (e) Compliance demonstration with the operational and work practice 
standards. (1) Fugitive dust sources. Failure to have a fugitive dust 
control plan or failure to report deviations from the plan and take 
necessary corrective action would be a violation of the general duty to 
ensure that fugitive dust sources are operated and maintained in a 
manner consistent with good air pollution control practices for 
minimizing emissions per Sec. 63.6(e)(1)(i) of subpart A.
    (2) Baghouses equipped with bag leak detection systems. The owner or 
operator demonstrates compliance with the bag leak detection system 
requirements by submitting reports as required by Sec. 63.1659(b)(5) 
showing that the alarm on the system does not sound for more than 5 
percent of the total operating time in a 6-month period. Calculate the 
percentage of total operating time the alarm on the bag leak detection 
system sounds as follows:
    (i) Do not include alarms that occur due solely to a malfunction of 
the bag leak detection system in the calculation.
    (ii) Do not include alarms that occur during startup, shutdown, and 
malfunction in the calculation if the condition is described in the 
startup, shutdown, and malfunction plan and the owner or operator 
follows all the procedures in the plan defined for this condition.
    (iii) Count 1 hour of alarm time for each alarm where the owner or 
operator initiates procedures to determine the cause within 1 hour of 
the alarm.

[[Page 196]]

    (iv) Count the actual time it takes the owner or operator to 
initiate procedures to determine the cause of the alarm for each alarm 
where the owner or operator does not initiate procedures to determine 
the cause within 1 hour of the alarm.
    (v) Calculate the percentage of time the alarm on the bag leak 
detection system sounds as the ratio of the sum of alarm times to the 
total operating time multiplied by 100.



Sec. 63.1657  Monitoring requirements.

    (a) Baghouses. (1) For the baghouses serving the submerged arc 
furnaces, the metal oxygen refining process, and crushing and screening 
operations, the owner or operator must observe on a daily basis for the 
presence of any visible emissions.
    (2) In addition to the daily visible emissions observation, the 
owner or operator must conduct the following activities:
    (i) Daily monitoring of pressure drop across each baghouse cell, or 
across the baghouse if it is not possible to monitor each cell 
individually, to ensure the pressure drop is within the normal operating 
range identified in the baghouse maintenance plan.
    (ii) Weekly confirmation that dust is being removed from hoppers 
through visual inspection, or equivalent means of ensuring the proper 
functioning of removal mechanisms.
    (iii) Daily check of compressed air supply for pulse-jet baghouses.
    (iv) An appropriate methodology for monitoring cleaning cycles to 
ensure proper operation.
    (v) Monthly check of bag cleaning mechanisms for proper functioning 
through visual inspection or equivalent means.
    (vi) Quarterly visual check of bag tension on reverse air and 
shaker-type baghouses to ensure that the bags are not kinked (kneed or 
bent) or laying on their sides. Such checks are not required for shaker-
type baghouses using self-tensioning (spring loaded) devices.
    (vii) Quarterly confirmation of the physical integrity of the 
baghouse structure through visual inspection of the baghouse interior 
for air
