                               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, 2003), consult the ``List of CFR 
Sections Affected (LSA),'' which is issued monthly, and the ``Cumulative 
List of Parts Affected,'' which appears in the Reader Aids section of 
the daily Federal Register. These two lists will identify the Federal 
Register page number of the latest amendment of any given rule.

EFFECTIVE AND EXPIRATION DATES

    Each volume of the Code contains amendments published in the Federal 
Register since the last revision of that volume of the Code. Source 
citations for the regulations are referred to by volume number and page 
number of the Federal Register and date of publication. Publication 
dates and effective dates are usually not the same and care must be 
exercised by the user in determining the actual effective date. In 
instances where the effective date is beyond the cut-off date for the 
Code a note has been inserted to reflect the future effective date. In 
those instances where a regulation published in the Federal Register 
states a date certain for expiration, an appropriate note will be 
inserted following the text.

OMB CONTROL NUMBERS

    The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires 
Federal agencies to display an OMB control number with their information 
collection request. 

[[Page vi]]

Many agencies have begun publishing numerous OMB control numbers as 
amendments to existing regulations in the CFR. These 
OMB numbers are placed as close as possible to the applicable 
recordkeeping or reporting requirements.

OBSOLETE PROVISIONS

    Provisions that become obsolete before the revision date stated on 
the cover of each volume are not carried. Code users may find the text 
of provisions in effect on a given date in the past by using the 
appropriate numerical list of sections affected. For the period before 
January 1, 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

                        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

[[Page 28]]

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 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.

[[Page 29]]

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 
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).
    (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

[[Page 30]]

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.
    (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).

[[Page 31]]

    (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.
    (1) Gas stream discharged from a copper concentrate dryer vent that 
would otherwise be subject to Sec. 63.1444(a)(1) or (2);
    (2) Gas stream discharged from a smelting furnace capture system 
that would otherwise be subject to Sec. 63.1444(b)(2)(ii);
    (3) Process off-gas stream discharged from a slag cleaning vessel 
that would otherwise be subject to Sec. 63.1444(c)(2);
    (4) Gas stream discharged from a slag cleaning vessel capture system 
that would otherwise be subject to Sec. 63.1444(c)(3)(ii); and

and (2) of this section for the combined gas stream discharged through a 
single vent.
    (1) For each combined gas stream discharged through a single vent, 
you must not cause to be discharged to the atmosphere any gases that 
contain total particulate matter in excess of the emission limit 
calculated using the procedure in paragraph (b)(2) of this section and 
measured using the test methods specified in Sec. 63.1450(a).
    (2) You must calculate the alternative total particulate matter 
emission limit for your combined gas stream using Equation 1 of this 
section. The volumetric flow rate value for each of the individual 
affected source gas streams that you use for Equation 1 (i.e., the flow 
rate of the gas stream discharged from the affected source but before 
this gas stream is combined with the other gas streams) is to be the 
average of the volumetric flow rates measured using the test method 
specified in Sec. 63.1450(a)(1)(ii):

                 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)

[[Page 33]]

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. 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

[[Page 34]]

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



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 
specified in sections 4.1 through 4.3 of Method 5D.
    (3) You must conduct three separate test runs for each performance 
test. Each test run must have a minimum sampling time of 60 minutes and 
a minimum sampling volume of 0.85 dscm. For the purpose of determining 
compliance with the applicable total particulate matter emission limit, 
the arithmetic mean of the results for the three separate test runs is 
used.
    (4) For a venturi wet scrubber applied to emissions from an affected 
source and subject to operating limits in Sec. 63.1444(g) or 
Sec. 63.1446(d) for pressure drop and scrubber water flow rate, you must 
establish site-specific operating limits according to the procedures in 
paragraph (a)(4)(i) and (ii) of this section.

flow rate during each run of the particulate matter performance test.
    (ii) Compute and record the hourly average pressure drop and 
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 
representative and reliable indicators of the control device 
performance, you must establish a site-specific operating limit(s) 
according to the procedures in paragraph (a)(5)(i) through (iv) of this 
section.

selected operating parameters for the control device during each run of 
the total particulate matter performance test.
    (iii) Compute and record the hourly average value for each of the 
selected operating parameters for each individual test run. Your 
operating limits are the lowest value or the highest value, as 
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.

[[Page 36]]

    (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.

a minimum sampling volume of 3.4 dscm. For the purpose of determining 
compliance with the nonsulfuric acid particulate matter emission limit, 
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 
attend the test. Written notification of the location and scheduled date

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

[[Page 37]]

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.
    (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.

[[Page 38]]

    (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;
    (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.

[[Page 39]]

    (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.

electrical connections for continuity, and all mechanical connections 
for leakage.
    (2) For the scrubber water flow rate CPMS, you must meet the 
requirements in paragraphs (c)(2)(i) through (iv) of this section.
    (i) Locate the flow sensor and other necessary equipment in a

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.

containing one or more group 1 furnace emission units processing other 
than clean charge.
    (d) The requirements of this subpart do not apply to facilities and 
equipment used for research and development that are not used to produce 
a saleable product.
    (e) The owner or operator of a secondary aluminum production 
facility 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

[[Page 54]]

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 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.

[[Page 55]]

    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.
    Internal runaround means scrap material generated on-site by 
aluminum extruding, rolling, scalping, forging, forming/stamping, 
cutting, and trimming operations that do not contain paint or solid 
coatings. Aluminum chips generated by turning, boring, milling, and 
similar machining operations that have not been dried at 343 [deg]C (650 
[deg]F) or higher, or by an equivalent non-thermal drying process, are 
not considered internal runaround.
    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 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.

[[Page 56]]

    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.
    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).

satisfies all requirements of this section and is otherwise consistent 
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.
    (2) A monitoring schedule for each affected source and emission 
unit.

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 
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.
    (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

[[Page 71]]

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 certification 
must contain the information in Sec. 63.1516(b)(2)(iv).
    (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/
charge materials, the plan must include provisions for the demonstration 
and implementation of the program in accordance with all applicable 
requirements in paragraph (p) of this section.
    (8) If a site-specific monitoring plan includes a calculation method 
for monitoring the scrap contaminant level of furnace feed/charge 
materials, the plan must include provisions for the demonstration and 
implementation of the program in accordance with all applicable 
requirements in paragraph (q) of this section.
    (p) Scrap inspection program for group 1 furnace without add-on air 
pollution control devices. A scrap inspection program must include:
    (1) A proven method for collecting representative samples and 
measuring the oil and coatings content of scrap samples;
    (2) A scrap inspector training program;
    (3) An established correlation between visual inspection and 
physical measurement of oil and coatings content of scrap samples;
    (4) Periodic physical measurements of oil and coatings content of 
randomly-selected scrap samples and comparison with visual inspection 
results;
    (5) A system for assuring that only acceptable scrap is charged to 
an affected group 1 furnace; and
    (6) Recordkeeping requirements to document conformance with plan 
requirements.
    (q) Monitoring of scrap contamination level by calculation method 
for group 1 furnace without add-on air pollution control devices. The 
owner or operator of a group 1 furnace dedicated to processing a 
distinct type of furnace feed/charge composed of scrap with a uniform 
composition (such as rejected product from a manufacturing process for 
which the coating-to-scrap ratio can be documented) may include a 
program in the site-specific monitoring plan for determining, 
monitoring, and certifying the scrap contaminant level using a 
calculation method rather than a scrap inspection program. A scrap 
contaminant monitoring program using a calculation method must include:
    (1) Procedures for the characterization and documentation of the 
contaminant level of the scrap prior to the performance test.
    (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 
the proportion used during the performance test.
    (3) Operating, monitoring, recordkeeping, and reporting requirements 
to ensure that no scrap with a contaminant level higher than that used 
in the performance test is charged to the furnace.

[[Page 72]]

    (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 information 
in Sec. 63.1516(b)(2)(v).
    (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 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:

[[Page 73]]

[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);
ERi = The measured emission rate for emission unit i as 
determined in the performance test (lb/ton or [mu]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 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

[[Page 74]]

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 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.

[[Page 75]]

    (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 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).

[[Page 76]]

    (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 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

[[Page 77]]

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.
    (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 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.

[[Page 78]]

    (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 
[mu]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

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

[[Page 97]]

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 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.

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

[[Page 105]]

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

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,

2009, whichever comes first. If you don't comply with the emission 
limitations and work practice standards for existing catalytic cracking 
units by the specified date, you will be out-of-compliance with the 
requirements for catalytic cracking units beginning April 11, 2005.
    (iv) A brief description of interim emission control measures that 
will be taken to ensure proper operation and maintenance of the process

                     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 standards in this subpart. These deviations must be reported 
according to the requirements in Sec. 63.1575.
    (g) Consistent with Secs. 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,

[[Page 116]]

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, 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.

[[Page 117]]

    (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:
[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.

[[Page 118]]

    (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.

    (2) If you use a continuous opacity monitoring system to meet the 
NSPS opacity limit, you must conduct a performance evaluation of each 
continuous opacity monitoring system according to the requirements in 
Sec. 63.8 and Table 40 of this subpart. This requirement does not apply 
to an affected source subject to the NSPS that has already demonstrated 
initial compliance with the applicable performance specification.
    (3) As specified in Sec. 63.8(c)(4)(i), each continuous opacity 
monitoring system must complete a minimum of one cycle of sampling and

during that hour or if the continuous parameter monitoring system is 
out-of-control).
    (3) Each continuous parameter monitoring system must have valid 
hourly average data from at least 75 percent of the hours during which 
the process operated.

[[Page 119]]

    (4) Each continuous parameter monitoring system must determine and

the daily average of all recorded readings for each operating day. The 
daily average must cover a 24-hour period if operation is continuous or 
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.

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 is the approved alternative for monitoring gas flow rate? 
You can elect to 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). If you select 
this alternative, you must use the same procedure for the performance 
test and for monitoring after the performance test.
    (1) 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.
    (2) 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).
    (3) Calculate and record the hourly average actual exhaust gas flow 
rate using Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.019

Where:

Qgas = 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);
Qair = Volumetric flow rate of air to regenerator, as 
determined from the catalytic cracking unit control room 
instrumentations, dscfm;
Qoxy = Volumetric flow rate of oxygen-enriched air stream to 
regenerator, as determined from the catalytic cracking unit control room 
instrumentations, dscfm;
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

[[Page 120]]

Pvent = Absolute pressure in the vent measured as near as 
practical to the control device or opacity monitor, atm. When used in 
conjunction with opacity in the final vent stack, you can assume 
Pvent = 1 atm.

    (b) What is the approved alternative for monitoring pH levels? If 
you use a wet scrubber to control inorganic HAP emissions from your vent 
on a catalytic reforming unit, you can measure and record the pH of the 
water (or scrubbing liquid) exiting the scrubber 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.
    (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 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

                   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 Secs. 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 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 Secs. 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. 63.1573.
    (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) As specified in Sec. 63.9(b)(3), if you start 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 affected source, 
control system, and continuous monitoring system. 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.

[[Page 122]]

    (2) Each plan must include, at a minimum, the information specified 
in paragraphs (f)(2)(i) through (x) 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.
    (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 semi-regenerative catalytic reforming unit with an internal 
scrubbing system (i.e., no add-on control device) when you use a 
colormetric tube sampling system, including procedures for correcting 
for pressure (if applicable to the sampling equipment).
    (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.

    PM means, for the purposes of this subpart, emissions of particulate 
matter that serve as a surrogate measure of the total emissions of 
particulate matter and metal HAP contained in the particulate matter, 
including but not limited to: antimony, arsenic, beryllium, cadmium, 
chromium, cobalt, lead, manganese, nickel, and selenium as measured by 
Methods 5B or 5F in appendix A to part 60 of this chapter or by an 
approved alternative method.
    Process heater means an enclosed combustion device that primarily 
transfers heat liberated by burning fuel directly to process streams or 
to heat transfer liquids other than water.
    Process vent means, for the purposes of this subpart, a gas stream 
that is continuously or periodically discharged during normal operation 
of a catalytic cracking unit, catalytic reforming unit, or sulfur 
recovery unit, including gas streams that are discharged directly to the 
atmosphere, gas streams that are routed to a control device prior to 
discharge to the atmosphere, or gas streams that are diverted through a 
product recovery device line prior to control or discharge to the 
atmosphere.
    Reduced sulfur compounds means hydrogen sulfide, carbonyl sulfide, 
and carbon disulfide.
    Reduction control system means an emission control system which 
reduces emissions from sulfur recovery units by converting these 
emissions to hydrogen sulfide.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Semi-regenerative reforming means a catalytic reforming process 
characterized by shutdown of the entire reforming unit (e.g., which may 
employ three to four separate reactors) at specified intervals or at the 
owner's or operator's convenience for in situ catalyst regeneration.
    Sulfur recovery unit means a process unit that recovers elemental 
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.

organic compounds, excluding methane and ethane, 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 non-HAP VOC as measured by Method 25 or 25A in 
appendix A to part 60 of this chapter or an approved alternative method.
    TRS means, for the purposes of this subpart, emissions of total 
reduced sulfur compounds, expressed as an equivalent sulfur dioxide 
concentration, that serve as a surrogate measure of the total emissions 
of sulfide HAP carbonyl sulfide and carbon disulfide as measured by 
Method 15 in appendix A to part 60 of this chapter or by an approved 
alternative method.
    Work practice standard means any design, equipment, work practice,

\1\ If applicable, you can use the alternative in Sec.  63.1573 for gas flow rate instead of a continuous
  parameter monitoring system if you used the alternative method in the initial performance test. If so, you
  must continuously monitor and record the air flow rate to the regenerator and the temperature of the gases
  entering the control device as described in Sec.  63.1573. You must determine and record the hourly average
  gas flow rate using Equation 1 of Sec.  63.1573 and the daily average gas flow rate. You must maintain the
  daily average gas flow rate below the operating limit established during the performance test.

 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.
    (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

[[Page 165]]

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 Secs. 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 major source non-industrial POTW treatment plant which is 
a major source of HAP are as follows:

[[Page 166]]

    (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 for Sec. 63.1586, you must comply with the

[[Page 167]]

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 the month for all HAP 
from all wastewater units up to, but not including, secondary treatment 
units;

[[Page 168]]

    (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).

under Sec. 63.10(f), as defined in Sec. 63.90, and as required in this 
subpart.



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 a municipality (as defined by section

[[Page 171]]

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

[[Page 175]]

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.

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.

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

    (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.

          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,

[[Page 179]]

the owner or operator must establish as a site-specific operating 
parameter the lowest average pressure drop on 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

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 Secs. 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.

[[Page 180]]

    (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.
    (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 leaks.
    (viii) Semiannual inspection of fans for wear, material buildup, and 
corrosion through visual inspection, vibration detectors, or equivalent 
means.
    (3) In addition to meeting the requirements of paragraphs (a)(1) and 
(a)(2) of this section, the owner or operator of a new or reconstructed 
submerged arc furnace must install and continuously operate a bag leak 
detection system if the furnace primary and/or tapping emissions are 
ducted to a negative pressure baghouse or to a positive pressure 
baghouse equipped with a stack. The bag leak detection system must meet 
the following requirements:
    (i) The bag leak detection system must be certified by the 
manufacturer to be capable of detecting particulate matter emissions at 
concentrations of 10 milligrams per actual cubic meter (0.0044 grains 
per actual cubic foot) or less.
    (ii) The bag leak detection system sensor must provide output of 
relative particulate matter loadings, and the owner or operator must 
continuously record the output from the bag leak detection system.
    (iii) The bag leak detection system must be equipped with an alarm 
system that will sound when an increase in relative particulate loadings 
is detected over a preset level. The alarm must be located where it can 
be heard by the appropriate plant personnel.
    (iv) Each bag leak detection system that works based on the 
triboelectric effect must be installed, calibrated, operated, and 
maintained consistent with the U.S. Environmental Protection Agency 
guidance document ``Fabric Filter Bag Leak Detection Guidance'' (EPA-
454/R-98-015). Other bag leak detection systems must be installed, 
calibrated, and maintained consistent with the manufacturer's written 
specifications and recommendations.
    (v) The initial adjustment of the system must, at a minimum, consist 
of establishing the baseline output by adjusting the sensitivity (range) 
and the averaging period of the device, and establishing the alarm set 
points and the alarm delay time.

[[Page 181]]

    (vi) Following initial adjustment, the owner or operator must not 
adjust the sensitivity or range, averaging period, alarm set points, or 
alarm delay time, except as detailed in the maintenance plan required 
under Sec. 63.1655(b). In no event must the sensitivity be increased by 
more than 100 percent or decreased more than 50 percent over a 365-day 
period unless a responsible official certifies the baghouse has been 
inspected and found to be in good operating condition.
    (vii) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (4) As part of the maintenance plan required by Sec. 63.1655(b), the 
owner or operator must develop and implement corrective action 
procedures to be followed in the case of a bag leak detection system 
alarm (for baghouses equipped with such a system), the observation of 
visible emissions from the baghouse, or the indication through the 
periodic baghouse system inspections that the system is not operating 
properly. The owner or operator must initiate corrective action as soon 
as practicable after the occurrence of the observation or event 
indicating a problem.
    (5) The corrective action plan must include procedures used to 
determine the cause of an alarm or other indications of problems as well 
as actions to minimize emissions. These actions may include the 
following:
    (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 
repairing the bag leak detection system.
    (vi) Shutting down the process producing the particulate matter 
emissions.
    (6) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (a) of this section would be a violation 
of the general duty to operate in a manner consistent with good air 
pollution control practices that minimizes emissions per 
Sec. 63.6(e)(1)(i) of subpart A.
    (b) Venturi scrubbers. (1) The owner or operator must monitor the 
pressure drop across the venturi at least every 5 minutes and record the 
average hourly pressure drop. Measurement of an average hourly pressure 
drop less than the pressure drop operating parameter limit established 
during a successful compliance demonstration would be a violation of the 
applicable emission standard, unless the excursion in the pressure drop 
is due to a malfunction.
    (2) As part of the maintenance plan required by Sec. 63.1655(b), the 
owner or operator must develop and implement corrective action 
procedures to be followed in the case of a violation of the pressure 
drop requirement. The owner or operator must initiate corrective action 
as soon as practicable after the excursion.
    (3) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (b) of this section is a violation of the 
general duty to operate in a manner consistent with good air pollution 
control practices that minimizes emissions per Sec. 63.6(e)(1)(i).
    (c) Shop opacity. The owner or operator subject to the opacity 
standards in Sec. 63.1653 must comply with one of the monitoring options 
in paragraphs (c)(1), (c)(2) or (c)(3) of this section. The selected 
option must be consistent with that selected during the initial 
performance test described in Sec. 63.1656(d)(2). Alternatively, the 
owner or operator may use the provisions of Sec. 63.8(f) to request 
approval to use an alternative monitoring method.
    (1) The owner or operator must check and record the control system 
fan motor amperes and capture system damper positions once per shift.
    (2) The owner or operator must install, calibrate, and maintain a 
monitoring device that continuously records the volumetric flow rate 
through each separately ducted hood.
    (3) The owner or operator must install, calibrate, and maintain a 
monitoring device that continuously records the volumetric flow rate at 
the inlet of

[[Page 182]]

the air pollution control device and must check and record the capture 
system damper positions once per shift.
    (4) The flow rate monitoring devices must meet the following 
requirements:
    (i) Be installed in an appropriate location in the exhaust duct such 
that reproducible flow rate monitoring will result.
    (ii) Have an accuracy [plusmn]10 percent over its normal operating 
range and be calibrated according to the manufacturer's instructions.
    (5) The Administrator may require the owner or operator to 
demonstrate the accuracy of the monitoring device(s) relative to Methods 
1 and 2 of appendix A of part 60 of this chapter.
    (6) Failure to maintain the appropriate capture system parameters 
(fan motor amperes, flow rate, and/or damper positions) establishes the 
need to initiate corrective action as soon as practicable after the 
monitoring excursion in order to minimize excess emissions.
    (7) Failure to monitor or failure to take corrective action under 
the requirements of paragraph (c) of this section is a violation of the 
general duty to operate in a manner consistent with good air pollution 
control practices that minimizes emissions per Sec. 63.6(e)(1)(i).

                                Standards



Sec. 63.1955  What requirements must I meet?

    (a) You must fulfill one of the requirements in paragraph (a)(1) or 
(2) of this section, whichever is applicable:
    (1) Comply with the requirements of 40 CFR part 60, subpart WWW.
    (2) Comply with the requirements of the Federal plan or EPA approved 
and effective State plan or tribal plan that implements 40 CFR part 60, 
subpart Cc.
    (b) If you are required by 40 CFR 60.752(b)(2) of subpart WWW, the 
Federal plan, or an EPA approved and effective State or tribal plan to 
install a collection and control system, you must comply with the 
requirements in Secs. 63.1960 through 63.1985 and with the general 
provisions of this part specified in table 1 of this subpart.
    (c) For approval of collection and control systems that include any 
alternatives to the operational standards, test methods, procedures, 
compliance measures, monitoring, recordkeeping or reporting provisions, 
you must follow the procedures in 40 CFR 60.752(b)(2). If alternatives 
have already been approved under 40 CFR part 60 subpart WWW or the 
Federal plan, or EPA approved and effective State or tribal plan, these 
alternatives can be used to comply with this subpart, except that all 
affected sources must comply with the SSM requirements in Subpart A of 
this part as specified in Table 1 of this subpart and all affected 
sources must submit compliance reports every 6 months as specified in 
Sec. 63.1980(a) and (b), including information on all deviations that 
occurred during the 6-month reporting period. Deviations for continuous 
emission monitors or numerical continuous parameter monitors must be 
determined using a 3 hour monitoring block average.
    (d) If you own or operate a bioreactor that is located at a MSW 
landfill that is not permanently closed and has a design capacity equal 
to or greater than 2.5 million Mg and 2.5 million m\3\, then you must 
meet the requirements of paragraph (a) and the additional requirements 
in paragraphs (d)(1) and (2) of this section.
    (1) You must comply with the general provisions specified in Table 1 
of this subpart and Secs. 63.1960 through 63.1985 starting on the date 
you are required to install the gas collection and control system.
    (2) You must extend the collection and control system into each new 
cell or area of the bioreactor prior to initiating liquids addition in 
that area, instead of the schedule in 40 CFR 60.752(b)(2)(ii)(A)(2).

             General and Continuing Compliance Requirements



Sec. 63.1960  How is compliance determined?

    Compliance is determined in the same way it is determined for 40 CFR 
part 60, subpart WWW, including performance testing, monitoring of the 
collection system, continuous parameter monitoring, and other credible 
evidence. In addition, continuous parameter monitoring data, collected 
under 40 CFR 60.756(b)(1), (c)(1), and (d) of subpart WWW, are used to 
demonstrate compliance with the operating conditions for control 
systems. If a deviation occurs, you have failed to meet the control 
device operating conditions described in this subpart and have deviated 
from the requirements of this subpart. Finally, you must develop and 
implement a written SSM plan according to the provisions in 40 CFR 
63.6(e)(3). A copy of the SSM plan must be maintained on site. Failure 
to write, implement, or maintain a copy of the SSM plan is a deviation 
from the requirements of this subpart.

[[Page 189]]



Sec. 63.1965  What is a deviation?

    A deviation is defined in Sec. 63.1990. For the purposes of the 
landfill monitoring and SSM plan requirements, deviations include the 
items in paragraphs (a) through (c) of this section.
    (a) A deviation occurs when the control device operating parameter 
boundaries described in 40 CFR 60.758(c)(1) of subpart WWW are exceeded.
    (b) A deviation occurs when 1 hour or more of the hours during the 
3-hour block averaging period does not constitute a valid hour of data. 
A valid hour of data must have measured values for at least three 15-
minute monitoring periods within the hour.
    (c) A deviation occurs when a SSM plan is not developed, 
implemented, or maintained on site.



Sec. 63.1975  How do I calculate the 3-hour block average used to demonstrate compliance?

    Averages are calculated in the same way as they are calculated in 40 
CFR part 60, subpart WWW, except that the data collected during the 
events listed in paragraphs (a), (b), (c), and (d) of this section are 
not to be included in any average computed under this subpart:
    (a) Monitoring system breakdowns, repairs, calibration checks, and 
zero (low-level) and high-level adjustments.
    (b) Startups.
    (c) Shutdowns.
    (d) Malfunctions.

                   Notifications, Records, and Reports



Sec. 63.1980  What records and reports must I keep and submit?

    (a) Keep records and reports as specified in 40 CFR part 60, subpart 
WWW, or in the Federal plan, EPA approved State plan or tribal plan that 
implements 40 CFR part 60, subpart Cc, whichever applies to your 
landfill, with one exception: You must submit the annual report 
described in 40 CFR 60.757(f) every 6 months.
    (b) You must also keep records and reports as specified in the 
general provisions of 40 CFR part 60 and this part as shown in Table 1 
of this subpart. Applicable records in the general provisions include 
items such as SSM plans and the SSM plan reports.
    (c) For bioreactors at new affected sources you must submit the 
initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) within 180 days after the date you are 
required to begin operating the gas collection and control system by 
Sec. 63.1947(a)(2) of this subpart.
    (d) For bioreactors at existing affected sources, you must submit 
the initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) within 180 days after the compliance date 
specified in Sec. 63.1947(b) of this subpart, unless you have previously 
submitted a compliance report for the bioreactor required by 40 CFR part 
60, subpart WWW, the Federal plan, or an EPA approved and effective 
State plan or tribal plan.
    (e) For bioreactors that are located at existing affected sources, 
but do not initiate liquids addition until later than the compliance 
date in Sec. 63.1947(b) of this subpart, you must submit the initial 
semiannual compliance report and performance tests results described in 
40 CFR 60.757(f) within 180 days after the date you are required to 
begin operating the gas collection and control system by Sec. 63.1947(c) 
of this subpart.
    (f) If you must submit a semiannual compliance report for a 
bioreactor as well as a semiannual compliance report for a conventional 
portion of the same landfill, you may delay submittal of a subsequent 
semiannual compliance report for the bioreactor according to paragraphs 
(f)(1) through (3) of this section so that the reports may be submitted 
on the same schedule.
    (1) After submittal of your initial semiannual compliance report and 
performance test results for the bioreactor, you may delay submittal of 
the subsequent semiannual compliance report for the bioreactor until the 
date the initial or subsequent semiannual compliance report is due for 
the conventional portion of your landfill.
    (2) You may delay submittal of your subsequent semiannual compliance 
report by no more than 12 months after the due date for submitting the 
initial semiannual compliance report and performance test results 
described in 40 CFR 60.757(f) for the bioreactor. The report shall cover 
the time period since the previous semiannual report for the

[[Page 190]]

bioreactor, which would be a period of at least 6 months and no more 
than 12 months.
    (3) After the delayed semiannual report, all subsequent semiannual 
reports for the bioreactor must be submitted every 6 months on the same 
date the semiannual report for the conventional portion of the landfill 
is due.
    (g) If you add any liquids other than leachate in a controlled 
fashion to the waste mass and do not comply with the bioreactor 
requirements in Secs. 63.1947, 63.1955(c) and 63.1980(c) through (f) of 
this subpart, you must keep a record of calculations showing that the 
percent moisture by weight expected in the waste mass to which liquid is 
added is less than 40 percent. The calculation must consider the waste 
mass, moisture content of the incoming waste, mass of water added to the 
waste including leachate recirculation and other liquids addition and 
precipitation, and the mass of water removed through leachate or other 
water losses. Moisture level sampling or mass balances calculations can 
be used. You must document the calculations and the basis of any 
assumptions. Keep the record of the calculations until you cease liquids 
addition.
    (h) If you calculate moisture content to establish the date your 
bioreactor is required to begin operating the collection and control 
system under Sec. 63.1947(a)(2) or (c)(2), keep a record of the 
calculations including the information specified in paragraph (g) of 
this section for 5 years. Within 90 days after the bioreactor achieves 
40 percent moisture content, report the results of the calculation, the 
date the bioreactor achieved 40 percent moisture content by weight, and 
the date you plan to begin collection and control system operation.

                   Other Requirements and Information



Sec. 63.1985  Who enforces this subpart?

    (a) This subpart can be implemented and enforced by the U.S. EPA, or 
a delegated authority such as the applicable State, local, or tribal 
agency. If the EPA Administrator has delegated authority to a State, 
local, or tribal agency, then that agency as well as the U.S. EPA has 
the authority to implement and enforce this subpart. Contact the 
applicable EPA Regional Office to find out if this subpart is delegated 
to a State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under subpart E of this 
part, the authorities contained in paragraph (c) of this section are 
retained by the EPA Administrator and are not transferred to the State, 
local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are as follows. Approval of alternatives to the 
standards in Sec. 63.1955. Where these standards reference another 
subpart, the cited provisions will be delegated according to the 
delegation provisions of the referenced subpart.



Sec. 63.1990  What definitions apply to this subpart?

part 60, subparts A, Cc, and WWW; 40 CFR part 62, subpart GGG, and 
subpart A of this part, and this section that follows:
    Bioreactor means a MSW landfill or portion of a MSW landfill where 
any liquid other than leachate (leachate includes landfill gas 
condensate) is added in a controlled fashion into the waste mass (often 
in combination with recirculating leachate) to reach a minimum average 
moisture content of at least 40 percent by weight to accelerate or 
enhance the anaerobic (without oxygen) biodegradation of the waste.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including, but not limited to, any emissions limitation 
(including any operating limit) or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limitation, (including any operating 
limit), or work practice standard in this subpart during SSM, regardless 
of whether

[[Page 191]]

or not such failure is permitted by this subpart.

Subpart CCCC--National Emission Standards for Hazardous Air Pollutants: 
                   Manufacturing of Nutritional Yeast

    Source: 66 FR 27884, May 21, 2001, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2130  What is the purpose of this subpart?

    This subpart establishes national emission limitations for hazardous 
air pollutants emitted from manufacturers of nutritional yeast. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.2131  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
nutritional yeast manufacturing facility that is, is located at, or is 
part of a major source of hazardous air pollutants (HAP) emissions.
    (1) A manufacturer of nutritional yeast is a facility that makes 
yeast for the purpose of becoming an ingredient in dough for bread or 
any other yeast-raised baked product, or for becoming a nutritional food 
additive intended for consumption by humans. A manufacturer of 
nutritional yeast does not include production of yeast intended for 
consumption by animals, such as an additive for livestock feed.
    (2) A major source of HAP emissions is any stationary source or 
group of stationary sources located within a contiguous area and under 
common control that emits or has the potential to emit, considering 
controls, any single HAP at a rate of 9.07 megagrams (10 tons) or more 
per year or any combination of HAP at a rate of 22.68 megagrams (25 
tons) or more per year.
    (b) [Reserved]



Sec. 63.2132  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
``affected source'' that produces Saccharomyces cerevisiae at a 
nutritional yeast manufacturing facility.
    (b) The affected source is the collection of equipment used in the 
manufacture of the nutritional yeast species Saccharomyces cerevisiae. 
This collection of equipment includes, but is not limited to, 
fermentation vessels (fermenters). The collection of equipment used in 
the manufacture of the nutritional yeast species Candida utilis (torula 
yeast) is not part of the affected source.
    (c) The emission limitations in this subpart apply to fermenters in 
the affected source that meet all of the criteria listed in paragraphs 
(c)(1) through (2) of this section.
    (1) The fermenters are ``fed-batch'' as defined in Sec. 63.2192.
    (2) The fermenters are used to support one of the last three 
fermentation stages in a production run, which may be referred to as 
``stock, first generation, and trade,'' ``seed, semi-seed, and 
commercial,'' or ``CB4, CB5, and CB6'' stages.
    (d) The emission limitations in this subpart do not apply to flask, 
pure-culture, yeasting-tank, or any other set-batch fermentation, and 
they do not apply to any operations after the last dewatering operation, 
such as filtration.
    (e) The emission limitations in this subpart do not apply to the 
affected source during the production of specialty yeast (defined in 
Sec. 63.2192).
    (f) An affected source is a ``new affected source'' if you commenced 
construction of the affected source after October 19, 1998, and you met 
the applicability criteria in Sec. 63.2131 at the time you commenced 
construction.

[[Page 193]]

    (g) An affected source is ``reconstructed'' if you meet the criteria 
as defined in Sec. 63.2.
    (h) An affected source is ``existing'' if it is not new or 
reconstructed.



Sec. 63.2133  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with paragraphs (a)(1) through (2) of this section.
    (1) If you start up your affected source before May 21, 2001, then 
you must comply with the emission limitations in this subpart no later 
than May 21, 2001.
    (2) If you start up your affected source after May 21, 2001, then 
you must comply with the emission limitations in this subpart upon 
startup of your affected source.
    (b) If you have an existing affected source, you must comply with 
the emission limitations for existing sources no later than May 21, 
2004.
    (c) If you have an area source that increases its emissions, or its 
potential to emit, so that it becomes a major source of HAP, paragraphs 
(c)(1) through (2) of this section apply.
    (1) Any portion of the existing facility 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 source must be in compliance with this 
subpart by not later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec. 63.2180 
according to the schedule in Sec. 63.2180 and in subpart A of this part.

                          Emission Limitations



Sec. 63.2140  What emission limitations must I meet?

    You must meet all of the emission limitations in Table 1 to this 
subpart.

                     General Compliance Requirements



Sec. 63.2150  What are my general requirements for complying with this subpart?

    (a) You must be in compliance with the emission limitations in Table 
1 to this subpart at all times, except during periods of malfunction.
    (b) You must always operate and maintain your affected source, 
including monitoring equipment, according to the provisions in 
Sec. 63.6(e)(1)(i). If the date upon which you must demonstrate initial 
compliance as specified in Sec. 63.2160 falls after the compliance date 
specified for your affected source in Sec. 63.2133, then you must 
maintain a log detailing the operation and maintenance of the continuous 
monitoring systems and the process and emissions control equipment 
during the period between those dates.
    (c) You must develop and implement a written malfunction plan. It 
will be as specified in Sec. 63.6(e)(3), except that the requirements 
for startup, shutdown, and maintenance plans, records and reports apply 
only to malfunctions. Under this subpart, a period of malfunction is 
expressed in whole batches and not in portions of batches.

               Testing and Initial Compliance Requirements



Sec. 63.2160  By what date must I conduct an initial compliance demonstration?

    (a) For each emission limitation in Table 1 to this subpart for 
which compliance is demonstrated by monitoring fermenter exhaust, you 
must demonstrate initial compliance for the period ending on the last 
day of the month that is 12 calendar months (or 11 calendar months, if 
the compliance date for your source is the first day of the month) after 
the compliance date that is specified for your source in Sec. 63.2133. 
(For example, if the compliance date is October 15, 2003, the first 12-
month period for which you must demonstrate compliance would be October 
15, 2003 through October 31, 2004.)
    (b) For each emission limitation in Table 1 to this subpart for 
which initial compliance is demonstrated by monitoring brew ethanol 
concentration and calculating volatile organic compound (VOC) 
concentration in the fermenter exhaust according to the procedures in 
Sec. 63.2161, you must demonstrate initial compliance within 180 
calendar days before the compliance date that is specified for your 
source in Sec. 63.2133.

[[Page 194]]



Sec. 63.2161  What performance tests and other procedures must I use if I monitor brew ethanol?

    (a) You must conduct each performance test in Table 2 to this 
subpart that applies to you.
    (b) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e)(1) and under the specific conditions that 
this subpart specifies in Table 2 to this subpart and in paragraphs 
(b)(1) through (4) of this section.
    (1) Conduct each performance test simultaneously with brew ethanol 
monitoring to establish a brew-to-exhaust correlation equation as 
specified in paragraph (f) of this section.
    (2) For each fermentation stage, conduct one run of the EPA Test 
Method 25A of 40 CFR part 60, appendix A, over the entire length of a 
batch. The three fermentation stages do not have to be from the same 
production run.
    (3) Do the test at a point in the exhaust-gas stream before you 
inject any dilution air, which is any air not needed to control 
fermentation.
    (4) Record the results of the test for each fermentation stage.
    (c) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (d) You must collect data to correlate the brew ethanol 
concentration measured by the continuous emission monitoring system 
(CEMS) to the VOC concentration in the fermenter exhaust according to 
paragraphs (d)(1) through (3) of this section.
    (1) You must collect a separate set of brew ethanol concentration 
data for each fed-batch fermentation stage while manufacturing the 
product that comprises the largest percentage (by mass) of average 
annual production.
    (2) Measure brew ethanol as specified in Sec. 63.2164 simultaneously 
with conducting a performance test for VOC in fermenter exhaust as 
specified in paragraph (b) of this section. You must measure brew 
ethanol at least once during each successive 30-minute period over the 
entire period of the performance test for VOC in fermenter exhaust.
    (3) Keep a record of the brew ethanol concentration data for each 
fermentation stage over the period of EPA Test Method 25A of 40 CFR part 
60, appendix A, performance test when the VOC concentration in the 
fermenter exhaust does not exceed the applicable emission limitation in 
Table 1 to this subpart.
    (e) For each set of data that you collected under paragraph (d) of 
this section, perform a linear regression of brew ethanol concentration 
(percent) on VOC fermenter exhaust concentration (parts per million by 
volume (ppmv) measured as propane). The correlation between the brew 
ethanol concentration as measured by the CEMS and the VOC fermenter 
exhaust concentration as measured by EPA Test Method 25A of 40 CFR part 
60, appendix A, must be linear with a correlation coefficient of at 
least 0.90.
    (f) Calculate the VOC concentration in the fermenter exhaust using 
the brew ethanol concentration data collected under paragraph (d) of 
this section and according to Equation 1 of this section.

BAVOC = BAE * CF + y (Eq. 1)

Where:

BAVOC = batch-average concentration of VOC in fermenter exhaust (ppmv 
          measured as propane), calculated for compliance demonstration
BAE = batch-average concentration of brew ethanol in fermenter liquid 
          (percent), measured by CEMS
CF = constant established at performance test and representing the slope 
          of the regression line
y = constant established at performance test and representing the y-
          intercept of the regression line



Sec. 63.2162  When must I conduct subsequent performance tests?

    (a) For each emission limitation in Table 1 to this subpart for 
which compliance is demonstrated by monitoring brew ethanol 
concentration and calculating VOC concentration in the fermenter exhaust 
according to the procedures in Sec. 63.2161, you must conduct an EPA 
Test Method 25A of 40 CFR part 60, appendix A, performance test and 
establish a brew-to-exhaust correlation according to the procedures in 
Table 2 to this subpart and in Sec. 63.2161, at least once every year.
    (b) The first subsequent performance test must be conducted no later 
than

[[Page 195]]

365 calendar days after the initial performance test conducted according 
to Sec. 63.2160. Each subsequent performance test must be conducted no 
later than 365 calendar days after the previous performance test. You 
must conduct a performance test for each 365 calendar day period for the 
lifetime of the affected source.



Sec. 63.2163  If I monitor fermenter exhaust, what are my monitoring installation, operation, and maintenance requirements?

    (a) Each CEMS must be installed, operated, and maintained according 
to the applicable Performance Specification (PS) of 40 CFR part 60, 
appendix B.
    (b) You must conduct a performance evaluation of each CEMS according 
to the requirements in Sec. 63.8, according to the applicable 
Performance Specification of 40 CFR part 60, appendix B, and according 
to paragraphs (b)(1) through (4) of this section.
    (1) If your CEMS monitor generates a single combined response value 
for VOC (examples of such detection principles are flame ionization, 
photoionization, and non-dispersive infrared absorption), but it is not 
a flame ionization analyzer, you must use PS 8 to show that your CEMS is 
operating properly.
    (i) Use EPA Test Method 25A of 40 CFR part 60, appendix A, to do the 
relative-accuracy test PS 8 requires.
    (ii) Calibrate the reference method with propane.
    (iii) Collect a 1-hour sample for each reference-method test.
    (2) If you continuously monitor VOC emissions using a flame 
ionization analyzer, then you must conduct the calibration drift test PS 
8 requires, but you are not required to conduct the relative-accuracy 
test PS 8 requires.
    (3) If you continuously monitor VOC emissions using gas 
chromatography, you must use PS 9 of CFR part 60, appendix B, to show 
that your CEMS is operating properly.
    (4) You must complete the performance evaluation and submit the 
performance evaluation report before the compliance date that is 
specified for your source in Sec. 63.2133.
    (c) Calibrate the CEMS with propane.
    (d) Set the CEMS span at not greater than 5 times the relevant 
emission limit, with 1.5 to 2.5 times the relevant emission limit being 
the range considered by us to be generally optimum.
    (e) You must monitor VOC concentration in fermenter exhaust at any 
point prior to dilution of the exhaust stream.
    (f) Each CEMS must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 30-minute 
period within each batch monitoring period. Except as specified in 
paragraph (g) of this section, you must have a minimum of two cycles of 
operation in a 1-hour period to have a valid hour of data.
    (g) The CEMS data must be reduced to arithmetic batch averages 
computed from two or more data points over each 1-hour period, except 
during periods when calibration, quality assurance, or maintenance 
activities pursuant to provisions of this part are being performed. 
During these periods, a valid hour of data shall consist of at least one 
data point representing a 30-minute period.
    (h) You must have valid CEMS data from at least 75 percent of the 
full hours over the entire batch monitoring period.
    (i) For each CEMS, record the results of each inspection, 
calibration, and validation check.
    (j) You must check the zero (low-level) and high-level calibration 
drifts for each CEMS in accordance with the applicable PS of 40 CFR part 
60, appendix B. The zero (low-level) and high-level calibration drifts 
shall be adjusted, at a minimum, whenever the zero (low-level) drift 
exceeds 2 times the limits of the applicable PS. The calibration drift 
checks must be performed at least once daily except that they may be 
performed less frequently under the conditions of paragraphs (j)(1) 
through (3) of this section.
    (1) If a 24-hour calibration drift check for your CEMS is performed 
immediately prior to, or at the start of, a batch monitoring period of a 
duration exceeding 24 hours, you are not required to perform 24-hour-
interval calibration drift checks during that batch monitoring period.
    (2) If the 24-hour calibration drift exceeds 2.5 percent of the span 
value (or

[[Page 196]]

more than 10 percent of the calibration gas value if your CEMS is a gas 
chromatograph (GC)) in fewer than 5 percent of the checks over a 1-month 
period, and the 24-hour calibration drift never exceeds 7.5 percent of 
the span value, then the frequency of calibration drift checks may be 
reduced to at least weekly (once every 7 days).
    (3) If, during two consecutive weekly checks, the weekly calibration 
drift exceeds 5 percent of the span value (or more than 20 percent of 
the calibration gas value, if your CEMS is a GC), then a frequency of at 
least 24-hour interval calibration checks must be resumed until the 24-
hour calibration checks meet the test of paragraph (j)(2) of this 
section.
    (k) If your CEMS is out of control, you must take corrective action 
according to paragraphs (k)(1) through (3) of this section.
    (1) Your CEMS is out of control if the zero (low-level) or high-
level calibration drift exceeds 2 times the limits of the applicable PS.
    (2) When the CEMS is out of control, take the necessary corrective 
action and repeat all necessary tests that indicate that the system is 
out of control. You must take corrective action and conduct retesting 
until the performance requirements are below the applicable limits.
    (3) During the batch monitoring periods in which the CEMS is out of 
control, recorded data shall not be used in data averages and 
calculations, or to meet any data availability requirement established 
under this subpart. The beginning of the out-of-control period is the 
beginning of the first batch monitoring period that follows the most 
recent calibration drift check during which the system was within 
allowable performance limits. The end of the out-of-control period is 
the end of the last batch monitoring period before you have completed 
corrective action and successfully demonstrated that the system is 
within the allowable limits. If your successful demonstration that the 
system is within the allowable limits occurs during a batch monitoring 
period, then the out-of-control period ends at the end of that batch 
monitoring period. If the CEMS is out of control for any part of a 
particular batch monitoring period, it is out of control for the whole 
batch monitoring period.



Sec. 63.2164  If I monitor brew ethanol, what are my monitoring installation, operation, and maintenance requirements?

    (a) Each CEMS must be installed, operated, and maintained according 
to manufacturer's specifications and the plan for malfunctions that you 
must develop and use according to Sec. 63.6(e).
    (b) Each CEMS must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 30-minute 
period within each batch monitoring period. Except as specified in 
paragraph (c) of this section, you must have a minimum of two cycles of 
operation in a 1-hour period to have a valid hour of data.
    (c) The CEMS data must be reduced to arithmetic batch averages 
computed from two or more data points over each 1-hour period, except 
during periods when calibration, quality assurance, or maintenance 
activities pursuant to provisions of this part are being performed. 
During these periods, a valid hour of data shall consist of at least one 
data point representing a 30-minute period.
    (d) You must have valid CEMS data from at least 75 percent of the 
full hours over the entire batch monitoring period.
    (e) Set the CEMS span to correspond to not greater than 5 times the 
relevant emission limit, with 1.5 to 2.5 times the relevant emission 
limit being the range considered by us to be generally optimum. Use the 
brew-to-exhaust correlation equation established under Sec. 63.2161(f) 
to determine the span value for your CEMS that corresponds to the 
relevant emission limit.
    (f) For each CEMS, record the results of each inspection, 
calibration, and validation check.
    (g) The GC that you use to calibrate your CEMS must meet the 
requirements of paragraphs (g)(1) through (3) of this section.
    (1) Calibrate the GC at least daily, by analyzing standard solutions 
of ethanol in water (0.05 percent, 0.15 percent, and 0.3 percent).

[[Page 197]]

    (2) For use in calibrating the GC, prepare the standard solutions of 
ethanol using the procedures listed in paragraphs (g)(2)(i) through (vi) 
of this section.
    (i) Starting with 100 percent ethanol, dry the ethanol by adding a 
small amount of anhydrous magnesium sulfate (granular) to 15-20 
milliliters (ml) of ethanol.
    (ii) Place approximately 50 ml of water into a 100-ml volumetric 
flask and place the flask on a balance. Tare the balance. Weigh 2.3670 
grams of the dry (anhydrous) ethanol into the volumetric flask.
    (iii) Add the 100-ml volumetric flask contents to a 1000-ml 
volumetric flask. Rinse the 100-ml volumetric flask with water into the 
1000-ml flask. Bring the volume to 1000 ml with water.
    (iv) Place an aliquot into a sample bottle labeled ``0.3% Ethanol.''
    (v) Fill a 50-ml volumetric flask from the contents of the 1000-ml 
flask. Add the contents of the 50-ml volumetric flask to a 100-ml 
volumetric flask and rinse the 50-ml flask into the 100-ml flask with 
water. Bring the volume to 100 ml with water. Place the contents into a 
sample bottle labeled ``0.15% Ethanol.''
    (vi) With a 10-ml volumetric pipette, add two 10.0-ml volumes of 
water to a sample bottle labeled ``0.05% Ethanol.'' With a 10.0-ml 
volumetric pipette, pipette 10.0 ml of the 0.15 percent ethanol solution 
into the sample bottle labeled ``0.05% Ethanol.''
    (3) For use in calibrating the GC, dispense samples of the standard 
solutions of ethanol in water in aliquots to appropriately labeled and 
dated glass sample bottles fitted with caps having a Teflon[reg] seal. 
Refrigerated samples may be kept unopened for 1 month. Prepare new 
calibration standards of ethanol in water at least monthly.
    (h) Calibrate the CEMS according to paragraphs (h)(1) through (3) of 
this section.
    (1) To calibrate the CEMS, inject a brew sample into a calibrated GC 
and compare the simultaneous ethanol value given by the CEMS to that 
given by the GC. Use either the Porapak[reg] Q, 80-100 mesh, 6[min] x 
\1/8\[min], stainless steel packed column or the DB Wax, 0.53 mm x 30 m 
capillary column.
    (2) If a CEMS ethanol value differs by 20 percent or more from the 
corresponding GC ethanol value, determine the brew ethanol values 
throughout the rest of the batch monitoring period by injecting brew 
samples into the GC not less frequently than every 30 minutes. From the 
time at which the difference of 20 percent or more is detected until the 
batch monitoring period ends, the GC data will serve as the CEMS data.
    (3) Perform a calibration of the CEMS at least four times per batch.



Sec. 63.2165  How do I demonstrate initial compliance with the emission limitations if I monitor fermenter exhaust?

    (a) You must demonstrate initial compliance with each emission 
limitation that applies to you according to Table 3 to this subpart.
    (b) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.2180(e).



Sec. 63.2166  How do I demonstrate initial compliance with the emission limitations if I monitor brew ethanol?

    (a) You must demonstrate initial compliance with each emission 
limitation that applies to you according to Table 3 to this subpart.
    (b) You must establish the brew-to-exhaust correlation for each 
fermentation stage according to Sec. 63.2161(e).
    (c) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.2180(e).

                   Continuous Compliance Requirements



Sec. 63.2170  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously during each batch monitoring period.

[[Page 198]]

    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, and required quality assurance or quality control 
activities in data averages and calculations used to report emission or 
operating levels, or to fulfill a minimum data availability requirement. 
You must use all the data collected during all other periods in 
assessing the operation of the control system.



Sec. 63.2171  How do I demonstrate continuous compliance with the emission limitations?

    (a) You must demonstrate continuous compliance with each emission 
limitation in Table 1 to this subpart that applies to you according to 
methods specified in Table 4 to this subpart.
    (b) You must calculate the percentage of within-concentration 
batches (defined in Sec. 63.2192) for each 12-month period according to 
paragraphs (b)(1) through (4) of this section.
    (1) Determine the percentage of batches over a 12-month calculation 
period that were in compliance with the applicable maximum 
concentration. The total number of batches in the calculation period is 
the sum of the numbers of batches of each fermentation stage for which 
emission limits apply. To calculate the 12-month percentage, do not 
include batches in production during periods of malfunction. In counting 
the number of batches in the 12-month calculation period, include those 
batches for which the batch monitoring period ended on or after 12 a.m. 
on the first day of the period and exclude those batches for which the 
batch monitoring period did not end on or before 11:59 p.m. on the last 
day of the period.
    (2) You must determine the 12-month percentage at the end of each 
calendar month.
    (3) The first 12-month calculation period begins on the compliance 
date that is specified for your source in Sec. 63.2133 and ends on the 
last day of the month that includes the date 365 days after your 
compliance date, unless the compliance date for your source is the first 
day of the month, in which case the first 12-month calculation period 
ends on the last day of the month that is 11 calendar months after the 
compliance date. (For example, if the compliance date for your source is 
October 15, 2003, the first 12-month calculation period would begin on 
October 15, 2003, and end on October 31, 2004. If the compliance date 
for your source is October 1, 2003, the first 12-month calculation 
period would begin on October 1, 2003, and end on September 30, 2004.)
    (4) The second 12-month calculation period and each subsequent 12-
month calculation period begin on the first day of the month following 
the first full month of the previous 12-month averaging period and end 
on the last day of the month 11 calendar months later. (For example, if 
the compliance date for your source is October 15, 2003, the second 
calculation period would begin on December 1, 2003 and end on November 
30, 2004.)
    (c) You must report each instance (that is, each 12-month 
calculation period) in which you did not meet each emission requirement 
in Table 4 to this subpart that applies to you. (Failure of a single 
batch to meet a concentration limit does not in and of itself constitute 
a failure to meet the emission limitation.) Each instance in which you 
failed to meet each applicable emission limitation is reported as part 
of the requirements in Sec. 63.2181.
    (d) During periods of malfunction, you must operate in accordance 
with the malfunction plan.

                   Notification, Reports, and Records



Sec. 63.2180  What notifications must I submit and when?

    (a) You must submit all of the notifications in Secs. 63.7(b) and 
(c), 63.8(e), (f)(4) and (6), and 63.9(b) through (h) that apply to you 
by the dates specified.
    (b) If you start up your affected source before May 21, 2001, you 
are not subject to the initial notification requirements of 
Sec. 63.9(b)(2).
    (c) If you are required to conduct a performance test as specified 
in Table 2 to this subpart, you must submit a notification of intent to 
conduct a performance test at least 60 calendar days before the 
performance test is scheduled to begin as required in Sec. 63.7(b)(1).
    (d) If you are required to conduct a performance evaluation as 
specified in

[[Page 199]]

Sec. 63.2163(b), you must submit a notification of the date of the 
performance evaluation at least 60 days prior to the date the 
performance evaluation is scheduled to begin as required in 
Sec. 63.8(e)(2).
    (e) If you are required to conduct a performance test or other 
initial compliance demonstration as specified in Table 2 or 3 to this 
subpart, you must submit a Notification of Compliance Status according 
to Sec. 63.9(h)(2)(ii) and according to paragraphs (e)(1) through (2) of 
this section.
    (1) For each initial compliance demonstration required in Table 3 to 
this subpart that does not include a performance test, you must submit 
the Notification of Compliance Status no later than July 31 or January 
31, whichever date follows the end of the first 12 calendar months after 
the compliance date that is specified for your source in Sec. 63.2133. 
If your initial compliance demonstration does not include a performance 
test, the first compliance report, described in Sec. 63.2181(b)(1), 
serves as the Notice of Compliance Status.
    (2) For each initial compliance demonstration required in Table 2 or 
3 to this subpart that includes a performance test conducted according 
to the requirements in Table 2, you must submit the Notification of 
Compliance Status, including the performance test results, before the 
close of business on the 60th calendar day following the completion of 
the performance test according to Sec. 63.10(d)(2).



Sec. 63.2181  What reports must I submit and when?

    (a) You must submit each report in Table 5 to this subpart that 
applies to you.
    (b) Unless the Administrator has approved a different schedule for 
submission of reports under Sec. 63.10(a), you must submit each report 
by the date in Table 5 to this subpart and according to paragraphs 
(b)(1) through (5) of this section.
    (1) The first compliance report must cover the period beginning on 
the compliance date that is specified for your affected source in 
Sec. 63.2133 and ending on either June 30 or December 31 (use whichever 
date is the first date following the end of the first 12 calendar months 
after the compliance date that is specified for your source in 
Sec. 63.2133). The first compliance report must include the percentage 
of within-concentration batches, as described in Sec. 63.2171(b), for 
the first 12-month calculation period described in Sec. 63.2171(b)(3). 
It must also include a percentage for each subsequent 12-month 
calculation period, as described in Sec. 63.2171(b)(4), ending on a 
calendar month that falls within the first compliance period. (For 
example, if the compliance date for your source is October 15, 2003, the 
first compliance report would cover the period from October 15, 2003 to 
December 31, 2004. It would contain percentages for the 12-month periods 
ending October 31, 2004; November 30, 2004; and December 31, 2004.)
    (2) The first compliance report must be postmarked or delivered no 
later than July 31 or January 31, whichever date follows the end of the 
first 12 calendar months after the compliance date that is specified for 
your affected source in Sec. 63.2133.
    (3) Each subsequent compliance report must cover the semiannual 
reporting period from January 1 through June 30 or the semiannual 
reporting period from July 1 through December 31. Each subsequent 
compliance report must include the percentage of within-concentration 
batches for each 12-month calculation period ending on a calendar month 
that falls within the reporting period. (For example, if the compliance 
date for your source is October 15, 2003, the second compliance report 
would cover the period from January 1, 2005 through June 30, 2005. It 
would contain percentages for the 12-month periods ending January 31, 
2005; February 28, 2005; March 31, 2005; April 30, 2005; May 31, 2005; 
and June 30, 2005.)
    (4) Each subsequent compliance report must be postmarked or 
delivered no later than July 31 or January 31, whichever date is the 
first date following the end of the semiannual reporting period.
    (5) For each affected source that is subject to permitting 
regulations pursuant to 40 CFR part 70 or part 71, and if the permitting 
authority has established dates for submitting semiannual

[[Page 200]]

reports pursuant to 40 CFR 70.6(a)(3)(a)(iii)(A) or 40 CFR 
71.6(a)(3)(a)(iii)(A), you may submit the first and subsequent 
compliance reports according to the dates the permitting authority has 
established instead of according to the dates in paragraphs (b)(1) 
through (4) of this section.
    (c) The compliance report must contain the information listed in 
paragraphs (c)(1) through (5) of this section.
    (1) Company name and address.
    (2) Statement by a responsible official with that official's name, 
title, and signature, certifying the accuracy of the content of the 
report.
    (3) Date of report and beginning and ending dates of the reporting 
period.
    (4) Percentage of batches that are within-concentration batches for 
each 12-month period ending on a calendar month that falls within the 
reporting period.
    (5) If you had a malfunction during the reporting period and you 
took actions consistent with your malfunction plan, the compliance 
report must include the information in Sec. 63.10(d)(5)(i) for each 
malfunction.

Sec. 63.2192  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, in 40 
CFR 63.2, the General Provisions of this part, and in this section as 
follows:
    Batch means a single fermentation cycle in a single fermentation 
vessel (fermenter).
    Batch monitoring period means the period that begins at the later of 
either the start of aeration or the addition of yeast to the fermenter; 
the period ends at the earlier of either the end of aeration or the 
point at which the yeast has begun being emptied from the fermenter.
    Brew means the mixture of yeast and additives in the fermenter.
    Brew ethanol means the ethanol in fermenter liquid.
    Brew ethanol monitor means the monitoring system that you use to 
measure brew ethanol to demonstrate compliance with this subpart. The 
monitoring system includes a resistance element used as an ethanol 
sensor, with the measured resistance proportional to the concentration 
of ethanol in the brew.
    Brew-to-exhaust correlation means the correlation between the 
concentration of ethanol in the brew and the concentration of VOC in the 
fermenter exhaust. This correlation is specific to each fed-batch 
fermentation stage and is established while manufacturing the product 
that comprises the largest percentage (by mass) of average annual 
production.
    Emission limitation means any emission limit or operating limit.
    Fed-batch means the yeast is fed carbohydrates and additives during 
fermentation in the vessel. In contrast, carbohydrates and additives are 
added to ``set-batch'' fermenters only at the start of the batch.
    1-hour period means any 60-minute period commencing on the minute at 
which the batch monitoring period begins.
    Product means the yeast resulting from the final stage in a 
production run. Products are distinguished by yeast species, strain, and 
variety.
    Responsible official means responsible official as defined in 40 CFR 
70.2.

[[Page 202]]

    Specialty yeast includes but is not limited to yeast produced for 
use in wine, champagne, whiskey, and beer.
    Within-concentration batch means a batch for which the average VOC 
concentration is not higher than the maximum concentration that is 
allowed as part of the applicable emission limitation.

             Solvent Extraction for Vegetable Oil Production

    Source: 66 FR 19011, Apr. 12, 2001, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2830  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for emissions during vegetable oil production. 
This subpart limits hazardous air pollutant (HAP) emissions from 
specified vegetable oil production processes. This subpart also 
establishes requirements to demonstrate initial and continuous 
compliance with the emission standards.



Sec. 63.2831  Where can I find definitions of key words used in this subpart?

    You can find definitions of key words used in this subpart in 
Sec. 63.2872.



Sec. 63.2832  Am I subject to this subpart?

    (a) You are an affected source subject to this subpart if you meet 
all of the criteria listed in paragraphs (a)(1) and (2) of this section:
    (1) You own or operate a vegetable oil production process that is a 
major source of HAP emissions or is collocated within a plant site with 
other sources that are individually or collectively a major source of 
HAP emissions.
    (i) A vegetable oil production process is defined in Sec. 63.2872. 
In general, it is the collection of continuous process equipment and 
activities that produce crude vegetable oil and meal products by 
removing oil from oilseeds listed in Table 1 to Sec. 63.2840 through 
direct contact with an organic solvent, such as a hexane isomer blend.
    (ii) A major source of HAP emissions is a plant site that emits or 
has the potential to emit any single HAP at a rate of 10 tons (9.07 
megagrams) or more per year or any combination of HAP at a rate of 25 
tons (22.68 megagrams) or more per year.
    (2) Your vegetable oil production process processes any combination 
of eight types of oilseeds listed in paragraphs (a)(2)(i) through (viii) 
of this section:
    (i) Corn germ;
    (ii) Cottonseed;
    (iii) Flax;
    (iv) Peanut;
    (v) Rapeseed (for example, canola);
    (vi) Safflower;
    (vii) Soybean; and
    (viii) Sunflower.
    (b) You are not subject to this subpart if your vegetable oil 
production process meets any of the criteria listed in paragraphs (b)(1) 
through (4) of this section:
    (1) It uses only mechanical extraction techniques that use no 
organic solvent to remove oil from a listed oilseed.
    (2) It uses only batch solvent extraction and batch desolventizing 
equipment.
    (3) It processes only agricultural products that are not listed 
oilseeds as defined in Sec. 63.2872.
    (4) It functions only as a research and development facility and is 
not a major source.
    (c) As listed in Sec. 63.1(c)(5) of the General Provisions, if your 
HAP emissions increase such that you become a major source, then you are 
subject to all of the requirements of this subpart.



Sec. 63.2833  Is my source categorized as existing or new?

    (a) This subpart applies to each existing and new affected source. 
You must categorize your vegetable oil production process as either an 
existing or a new source in accordance with the criteria in Table 1 of 
this section, as follows:

  Table 1 to Sec.  63.2833--Categorizing Your Source as Existing or New

                                   years after the
                                   effective date of

                                   effective date of
                                   this subpart.
(6) began construction on or      ..................  is a new source.
 after May 26, 2000.
------------------------------------------------------------------------

    (b) Reconstruction of a source. Any affected source is reconstructed 
if components are replaced so that the criteria in the definition of 
reconstruction in Sec. 63.2 are satisfied. In general, a vegetable oil 
production process is reconstructed if the fixed capital cost of the new 
components exceeds 50 percent of the fixed capital cost for constructing 
a new vegetable oil production process, and it is technically and 
economically feasible for the reconstructed source to meet the relevant 
new source requirements of this subpart. The effect of reconstruction on 
the categorization of your existing and new affected source is described 
in paragraphs (b)(1) and (2) of this section:
    (1) After reconstruction of an existing source, the affected source 
is recategorized as a new source and becomes subject to the new source 
requirements of this subpart.
    (2) After reconstruction of a new source, the affected source 
remains categorized as a new source and remains subject to the new 
source requirements of this subpart.
    (c) Significant modification of a source. A significant modification 
to an affected source is a term specific to this subpart and is defined 
in Sec. 63.2872.
    (1) In general, a significant modification to your source consists 
of adding new equipment or the modification of existing equipment within 
the affected source that significantly affects solvent losses from the 
affected source. Examples include adding or replacing extractors, 
desolventizer-toasters (conventional and specialty), and meal dryer-
coolers. All other significant modifications must meet the criteria 
listed in paragraphs (c)(1)(i) and (ii) of this section:
    (i) The fixed capital cost of the modification represents a 
significant percentage of the fixed capital cost of building a 
comparable new vegetable oil production process.
    (ii) It does not constitute reconstruction as defined in Sec. 63.2.
    (2) A significant modification has no effect on the categorization 
of your source as existing and new. An existing source remains 
categorized as an existing source and subject to the existing source 
requirements of this subpart. A new source remains categorized as a new 
source and subject to the new source requirements of this subpart.
    (d) Changes in the type of oilseed processed by your affected source 
does not affect the categorization of your source as new or existing. 
Recategorizing an affected source from existing to new occurs only when 
you add or modify process equipment within the source which meets the 
definition of reconstruction.



Sec. 63.2834  When do I have to comply with the standards in this subpart?

    You must comply with this subpart in accordance with one of the 
schedules in Table 1 of this section, as follows:

------------------------------------------------------------------------

                                Standards



Sec. 63.2840  What emission requirements must I meet?

    (a)(1) The emission requirements limit the number of gallons of HAP 
lost per ton of listed oilseeds processed. For each operating month, you 
must calculate a compliance ratio which compares your actual HAP loss to 
your allowable HAP loss for the previous 12 operating months as shown in 
Equation 1 of this section. An operating month, as defined in 
Sec. 63.2872, is any calendar month in which a source processes a listed 
oilseed, excluding any entire calendar month in which the source 
operated under an initial startup period subject to Sec. 63.2850(c)(2) 
or (d)(2) or a malfunction period subject to Sec. 63.2850(e)(2). 
Equation 1 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.001

    (2) Equation 1 of this section can also be expressed as a function 
of total solvent loss as shown in Equation 2 of this section. Equation 2 
of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.002


Where:
f = The weighted average volume fraction of HAP in solvent received 
during the previous 12 operating months, as determined in Sec. 63.2854, 
dimensionless.
0.64 = The average volume fraction of HAP in solvent in the baseline 
performance data, dimensionless.
Actual Solvent Loss = Gallons of actual solvent loss during previous 12 
operating months, as determined in Sec. 63.2853.
Oilseed = Tons of each oilseed type ``i'' processed during the previous 
12 operating months, as shown in Sec. 63.2855.
SLF = The corresponding solvent loss factor (gal/ton) for oilseed ``i'' 
listed in Table 1 of this section, as follows:

    (b) When your source has processed listed oilseed for 12 operating 
months, calculate the compliance ratio by the end of each calendar month 
following an operating month using Equation 2 of this section. When 
calculating your compliance ratio, consider the conditions and 
exclusions in paragraphs (b)(1) through (6) of this section:
    (1) If your source processes any quantity of listed oilseeds in a 
calendar month and the source is not operating under an initial startup 
period or malfunction period subject to Sec. 63.2850, then you must 
categorize the month as an operating month, as defined in Sec. 63.2872.
    (2) The 12-month compliance ratio may include operating months 
occurring prior to a source shutdown and operating months that follow 
after the source resumes operation.
    (3) If your source shuts down and processes no listed oilseed for an 
entire calendar month, then you must categorize the month as a 
nonoperating month, as defined in Sec. 63.2872. Exclude any nonoperating 
months from the compliance ratio determination.
    (4) If your source is subject to an initial startup period as 
defined in Sec. 63.2872, exclude from the compliance ratio determination 
any solvent and oilseed information recorded for the initial startup 
period.
    (5) If your source is subject to a malfunction period as defined in 
Sec. 63.2872, exclude from the compliance ratio determination any 
solvent and oilseed information recorded for the malfunction period.
    (6) For sources processing cottonseed or specialty soybean, the 
solvent loss

[[Page 209]]

factor you use to determine the compliance ratio may change each 
operating month depending on the tons of oilseed processed during all 
normal operating periods in a 12 operating month period.
    (c) If the compliance ratio is less than or equal to 1.00, your 
source was in compliance with the HAP emission requirements for the 
previous operating month.
    (d) To determine the compliance ratio in Equation 2 of this section, 
you must select the appropriate oilseed solvent loss factor from Table 1 
of this section. First, determine whether your source is new or existing 
using Table 1 of Sec. 63.2833. Then, under the appropriate existing or 
new source column, select the oilseed solvent loss factor that 
corresponds to each type oilseed or process operation for each operating 
month.

                         Compliance Requirements



Sec. 63.2850  How do I comply with the hazardous air pollutant emission standards?

    (a) General requirements. The requirements in paragraphs (a)(1)(i) 
through (iv) of this section apply to all affected sources:
    (1) Submit the necessary notifications in accordance with 
Sec. 63.2860, which include:
    (i) Initial notifications for existing sources.
    (ii) Initial notifications for new and reconstructed sources.
    (iii) Initial notifications for significant modifications to 
existing or new sources.
    (iv) Notification of compliance status.
    (2) Develop and implement a plan for demonstrating compliance in 
accordance with Sec. 63.2851.
    (3) Develop a written startup, shutdown and malfunction (SSM) plan 
in accordance with the provisions in Sec. 63.2852.
    (4) Maintain all the necessary records you have used to demonstrate 
compliance with this subpart in accordance with Sec. 63.2862.
    (5) Submit the reports in paragraphs (a)(5)(i) through (iii) of this 
section:
    (i) Annual compliance certifications in accordance with 
Sec. 63.2861(a).
    (ii) Periodic SSM reports in accordance with Sec. 63.2861(c).
    (iii) Immediate SSM reports in accordance with Sec. 63.2861(d).
    (6) Submit all notifications and reports and maintain all records 
required by the General Provisions for performance testing if you add a 
control device that destroys solvent.
    (b) Existing sources under normal operation. You must meet all of 
the requirements listed in paragraph (a) of this section and Table 1 of 
this section for sources under normal operation, and the schedules for 
demonstrating compliance for existing sources under normal operation in 
Table 2 of this section.
    (c) New sources. Your new source, including a source that is 
categorized as new due to reconstruction, must meet the requirements 
associated with one of two compliance options. Within 15 days of the 
startup date, you must choose to comply with one of the options listed 
in paragraph (c)(1) or (2) of this section:
    (1) Normal operation. Upon startup of your new source, you must meet 
all of the requirements listed in Sec. 63.2850(a) and Table 1 of this 
section for sources under normal operation, and the schedules for 
demonstrating compliance for new sources under normal operation in Table 
2 of this section.
    (2) Initial startup period. For up to 6 calendar months after the 
startup date of your new source, you must meet all of the requirements 
listed in paragraph (a) of this section and Table 1 of this section for 
sources operating under an initial startup period, and the schedules for 
demonstrating compliance for new sources operating under an initial 
startup period in Table 2 of this section. After a maximum of 6 calendar 
months, your new source must then meet all of the requirements listed in 
Table 1 of this section for sources under normal operation.
    (d) Existing or new sources that have been significantly modified. 
Your existing or new source that has been significantly modified must 
meet the requirements associated with one of two compliance options. 
Within 15 days of the modified source startup date, you must

[[Page 210]]

choose to comply with one of the options listed in paragraph (d)(1) or 
(2) of this section:
    (1) Normal operation. Upon startup of your significantly modified 
existing or new source, you must meet all of the requirements listed in 
paragraph (a) of this section and Table 1 of this section for sources 
under normal operation, and the schedules for demonstrating compliance 
for an existing or new source that has been significantly modified in 
Table 2 of this section.
    (2) Initial startup period. For up to 3 calendar months after the 
startup date of your significantly modified existing or new source, you 
must meet all of the requirements listed in paragraph (a) of this 
section and Table 1 of this section for sources operating under an 
initial startup period, and the schedules for demonstrating compliance 
for a significantly modified existing or new source operating under an 
initial startup period in Table 2 of this section. After a maximum of 3 
calendar months, your new or existing source must meet all of the 
requirements listed in Table 1 of this section for sources under normal 
operation.
    (e) Existing or new sources experiencing a malfunction. A 
malfunction is defined in Sec. 63.2. In general, it means any sudden, 
infrequent, and not reasonably preventable failure of air pollution 
control equipment or process equipment to function in a usual manner. If 
your existing or new source experiences an unscheduled shutdown as a 
result of a malfunction, continues to operate during a malfunction 
(including the period reasonably necessary to correct the malfunction), 
or starts up after a shutdown resulting from a malfunction, then you 
must meet the requirements associated with one of two compliance 
options. Routine or scheduled process startups and shutdowns resulting 
from, but not limited to, market demands, maintenance activities, and 
switching types of oilseed processed, are not startups or shutdowns 
resulting from a malfunction and, therefore, do not qualify for this 
provision. Within 15 days of the beginning date of the malfunction, you 
must choose to comply with one of the options listed in paragraphs 
(e)(1) through (2) of this section:
    (1) Normal operation. Your source must meet all of the requirements 
listed in paragraph (a) of this section and one of the options listed in 
paragraphs (e)(1)(i) through (iii) of this section:
    (i) Existing source normal operation requirements in paragraph (b) 
of this section.
    (ii) New source normal operation requirements in paragraph (c)(1) of 
this section.
    (iii) Normal operation requirements for sources that have been 
significantly modified in paragraph (d)(1) of this section.
    (2) Malfunction period. Throughout the malfunction period, you must 
meet all of the requirements listed in paragraph (a) of this section and 
Table 1 of this section for sources operating during a malfunction 
period. At the end of the malfunction period, your source must then meet 
all of the requirements listed in Table 1 of this section for sources 
under normal operation. Table 1 of this section follows:

Sec. 63.2851  What is a plan for demonstrating compliance?

    (a) You must develop and implement a written plan for demonstrating 
compliance that provides the detailed procedures you will follow to 
monitor and record data necessary for demonstrating compliance with this 
subpart. Procedures followed for quantifying solvent loss from the 
source and amount of oilseed processed vary from source to source 
because of site-specific factors such as equipment design 
characteristics and operating conditions. Typical procedures include one 
or more accurate measurement methods such as weigh scales, volumetric 
displacement, and material mass balances. Because the industry does not 
have a uniform set of procedures, you must develop and implement your 
own site-specific plan for demonstrating compliance before the 
compliance date for your source. You must also incorporate the plan for 
demonstrating compliance by reference in the source's title V permit and 
keep the plan on-site and readily available as long as the source is 
operational. If you make any changes to the plan for demonstrating 
compliance, then you must keep all previous versions of the plan and 
make them readily available for inspection for at least 5 years after 
each revision. The plan for demonstrating compliance must include the 
items in paragraphs (a)(1) through (7) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) A detailed description of all methods of measurement your source 
will use to determine your solvent losses, HAP content of solvent, and 
the tons of each type of oilseed processed.
    (4) When each measurement will be made.
    (5) Examples of each calculation you will use to determine your 
compliance status. Include examples of how you will convert data 
measured with one parameter to other terms for use in compliance 
determination.
    (6) Example logs of how data will be recorded.
    (7) A plan to ensure that the data continue to meet compliance 
demonstration needs.
    (b) The responsible agency of these NESHAP may require you to revise 
your plan for demonstrating compliance. The responsible agency may 
require reasonable revisions if the procedures lack detail, are 
inconsistent or do not accurately determine solvent

[[Page 213]]

loss, HAP content of the solvent, or the tons of oilseed processed.



Sec. 63.2852  What is a startup, shutdown, and malfunction plan?

    You must develop a written SSM plan in accordance with 
Sec. 63.6(e)(3) and implement the plan, when applicable. You must 
complete the SSM plan before the compliance date for your source. You 
must also keep the SSM plan on-site and readily available as long as the 
source is operational.The SSM plan provides detailed procedures for 
operating and maintaining your source to minimize emissions during a 
qualifying SSM event for which the source chooses the Sec. 63.2850(e)(2) 
malfunction period, or the Sec. 63.2850(c)(2) or (d)(2) initial startup 
period. The SSM plan must specify a program of corrective action for 
malfunctioning process and air pollution control equipment and reflect 
the best practices now in use by the industry to minimize emissions. 
Some or all of the procedures may come from plans you developed for 
other purposes such as a Standard Operating Procedure manual or an 
Occupational Safety and Health Administration Process Safety Management 
plan. To qualify as a SSM plan, other such plans must meet all the 
applicable requirements of these NESHAP.

[66 FR 19011, Apr. 12, 2001, as amended at 67 FR 16321, Apr. 5, 2002]



Sec. 63.2853  How do I determine the actual solvent loss?

    By the end of each calendar month following an operating month, you 
must determine the total solvent loss in gallons for the previous 
operating month. The total solvent loss for an operating month includes 
all solvent losses that occur during normal operating periods within the 
operating month. If you have determined solvent losses for 12 or more 
operating months, then you must also determine the 12 operating months 
rolling sum of actual solvent loss in gallons by summing the monthly 
actual solvent loss for the previous 12 operating months. The 12 
operating months rolling sum of solvent loss is the ``actual solvent 
loss,'' which is used to calculate your compliance ratio as described in 
Sec. 63.2840.
    (a) To determine the actual solvent loss from your source, follow 
the procedures in your plan for demonstrating compliance to determine 
the items in paragraphs (a)(1) through (7) of this section:
    (1) The dates that define each operating status period during a 
calendar month. The dates that define each operating status period 
include the beginning date of each calendar month and the date of any 
change in the source operating status. If the source maintains the same 
operating status during an entire calendar month, these dates are the 
beginning and ending dates of the calendar month. If, prior to the 
effective date of this rule, your source determines the solvent loss on 
an accounting month, as defined in Sec. 63.2872, rather than a calendar 
month basis, and you have 12 complete accounting months of approximately 
equal duration in a calendar year, you may substitute the accounting 
month time interval for the calendar month time interval. If you choose 
to use an accounting month rather than a calendar month, you must 
document this measurement frequency selection in your plan for 
demonstrating compliance, and you must remain on this schedule unless 
you request and receive written approval from the agency responsible for 
these NESHAP.
    (2) Source operating status. You must categorize the operating 
status of your source for each recorded time interval in accordance with 
criteria in Table 1 of this section, as follows:

   Table 1 of Sec.  63.2853--Categorizing Your Source Operating Status
------------------------------------------------------------------------
 If during a recorded time interval . .     then your source operating
                   .                             status is . . .

(v) Your source processes agricultural   An exempt period.
 products not defined as listed oilseed.
------------------------------------------------------------------------

    (3) Measuring the beginning and ending solvent inventory. You are 
required to measure and record the solvent inventory on the beginning 
and ending dates of each normal operating period that occurs during an 
operating month. An operating month is any calendar month with at least 
one normal operating period. You must consistently follow the procedures 
described in your plan for demonstrating compliance, as specified in 
Sec. 63.2851, to determine the extraction solvent inventory, and 
maintain readily available records of the actual solvent loss inventory, 
as described in Sec. 63.2862(c)(1). In general, you must measure and 
record the solvent inventory only when the source is actively processing 
any type of agricultural product. When the source is not active, some or 
all of the solvent working capacity is transferred to solvent storage 
tanks which can artificially inflate the solvent inventory.
    (4) Gallons of extraction solvent received. Record the total gallons 
of extraction solvent received in each shipment. For most processes, the 
gallons of solvent received represents purchases of delivered solvent 
added to the solvent storage inventory. However, if your process refines 
additional vegetable oil from off-site sources, recovers solvent from 
the off-site oil, and adds it to the on-site solvent inventory, then you 
must determine the quantity of recovered solvent and include it in the 
gallons of extraction solvent received.
    (5) Solvent inventory adjustments. In some situations, solvent 
losses determined directly from the measured solvent inventory and 
quantity of solvent received is not an accurate estimate of the ``actual 
solvent loss'' for use in determining compliance ratios. In such cases, 
you may adjust the total solvent loss for each normal operating period 
as long as you provide a reasonable justification for the adjustment. 
Situations that may require adjustments of the total solvent loss 
include, but are not limited to, situations in paragraphs (a)(5)(i) and 
(ii) of this section:
    (i) Solvent destroyed in a control device. You may use a control 
device to reduce solvent emissions to meet the emission standard. The 
use of a control device does not alter the emission limit for the 
source. If you use a control device that reduces solvent emissions 
through destruction of the solvent instead of recovery, then determine 
the gallons of solvent that enter the control device and are destroyed 
there during each normal operating period. All solvent destroyed in a 
control device during a normal operating period can be subtracted from 
the total solvent loss. Examples of destructive emission control devices 
include catalytic incinerators, boilers, or flares. Identify and 
describe, in your plan for demonstrating compliance, each type of 
reasonable and sound measurement method that you use to quantify the 
gallons of solvent entering and exiting the control device and to 
determine the destruction efficiency of the control device. You may use 
design evaluations to document the gallons of solvent destroyed or 
removed by the control device instead of performance testing under 
Sec. 63.7. The design evaluations must be based on the procedures and 
options described in Sec. 63.985(b)(1)(i)(A) through (C) or Sec. 63.11, 
as appropriate. All data, assumptions, and procedures used in such 
evaluations must be documented and available for inspection. If you use 
performance testing to determine solvent flow rate to the control device 
or destruction efficiency of the device, follow the procedures as 
outlined in Sec. 63.997(e)(1) and (2). Instead of periodic performance 
testing to demonstrate continued good operation of the control device, 
you

[[Page 215]]

may develop a monitoring plan, following the procedures outlined in 
Sec. 63.988(c) and using operational parametric measurement devices such 
as fan parameters, percent measurements of lower explosive limits, and 
combustion temperature.
    (ii) Changes in solvent working capacity. In records you keep on-
site, document any process modifications resulting in changes to the 
solvent working capacity in your vegetable oil production process. 
Solvent working capacity is defined in Sec. 63.2872. In general, solvent 
working capacity is the volume of solvent normally retained in solvent 
recovery equipment such as the extractor, desolventizer-toaster, solvent 
storage, working tanks, mineral oil absorber, condensers, and oil/
solvent distillation system. If the change occurs during a normal 
operating period, you must determine the difference in working solvent 
volume and make a one-time documented adjustment to the solvent 
inventory.
    (b) Use Equation 1 of this section to determine the actual solvent 
loss occurring from your affected source for all normal operating 
periods recorded within a calendar month. Equation 1 of this section 
follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.003

Where:

SOLVB = Gallons of solvent in the inventory at the beginning 
of normal operating period ``i'' as determined in paragraph (a)(3) of 
this section.
SOLVE = Gallons of solvent in the inventory at the end of 
normal operating period ``i'' as determined in paragraph (a)(3) of this 
section.
SOLVR = Gallons of solvent received between the beginning and 
ending inventory dates of normal operating period ``i'' as determined in 
paragraph (a)(4) of this section.
SOLVA = Gallons of solvent added or removed from the 
extraction solvent inventory during normal operating period ``i'' as 
determined in paragraph (a)(5) of this section.
n = Number of normal operating periods in a calendar month.

    (c) The actual solvent loss is the total solvent losses during 
normal operating periods for the previous 12 operating months. You 
determine your actual solvent loss by summing the monthly actual solvent 
losses for the previous 12 operating months. You must record the actual 
solvent loss by the end of each calendar month following an operating 
month. Use the actual solvent loss in Equation 2 of Sec. 63.2840 to 
determine the compliance ratio. Actual solvent loss does not include 
losses that occur during operating status periods listed in paragraphs 
(c)(1) through (4) of this section. If any one of these four operating 
status periods span an entire month, then the month is treated as 
nonoperating and there is no compliance ratio determination.
    (1) Nonoperating periods as described in paragraph (a)(2)(ii) of 
this section.
    (2) Initial startup periods as described in Sec. 63.2850(c)(2) or 
(d)(2).
    (3) Malfunction periods as described in Sec. 63.2850(e)(2).
    (4) Exempt operation periods as described in paragraph (a)(2)(v) of 
this section.



Sec. 63.2854  How do I determine the weighted average volume fraction of HAP in the actual solvent loss?

    (a) This section describes the information and procedures you must 
use to determine the weighted average volume fraction of HAP in 
extraction solvent received for use in your vegetable oil production 
process. By the end of each calendar month following an operating month, 
determine the weighted average volume fraction of HAP in extraction 
solvent received since the end of the previous operating month. If you 
have determined the monthly weighted average volume fraction of HAP in 
solvent received for 12 or more operating

[[Page 216]]

months, then also determine an overall weighted average volume fraction 
of HAP in solvent received for the previous 12 operating months. Use the 
volume fraction of HAP determined as a 12 operating months weighted 
average in Equation 2 of Sec. 63.2840 to determine the compliance ratio.
    (b) To determine the volume fraction of HAP in the extraction 
solvent determined as a 12 operating months weighted average, you must 
comply with paragraphs (b)(1) through (3) of this section:
    (1) Record the volume fraction of each HAP comprising more than 1 
percent by volume of the solvent in each delivery of solvent, including 
solvent recovered from off-site oil. To determine the HAP content of the 
material in each delivery of solvent, the reference method is EPA Method 
311 of appendix A of this part. You may use EPA Method 311, an approved 
alternative method, or any other reasonable means for determining the 
HAP content. Other reasonable means of determining HAP content include, 
but are not limited to, a material safety data sheet or a manufacturer's 
certificate of analysis. A certificate of analysis is a legal and 
binding document provided by a solvent manufacturer. The purpose of a 
certificate of analysis is to list the test methods and analytical 
results that determine chemical properties of the solvent and the volume 
percentage of all HAP components present in the solvent at quantities 
greater than 1 percent by volume. You are not required to test the 
materials that you use, but the Administrator may require a test using 
EPA Method 311 (or an approved alternative method) to confirm the 
reported HAP content. However, if the results of an analysis by EPA 
Method 311 are different from the HAP content determined by another 
means, the EPA Method 311 results will govern compliance determinations.
    (2) Determine the weighted average volume fraction of HAP in the 
extraction solvent each operating month. The weighted average volume 
fraction of HAP for an operating month includes all solvent received 
since the end of the last operating month, regardless of the operating 
status at the time of the delivery. Determine the monthly weighted 
average volume fraction of HAP by summing the products of the HAP volume 
fraction of each delivery and the volume of each delivery and dividing 
the sum by the total volume of all deliveries as expressed in Equation 1 
of this section. Record the result by the end of each calendar month 
following an operating month. Equation 1 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.004

Where:

Receivedi = Gallons of extraction solvent received in 
delivery ``i.''
Contenti = The volume fraction of HAP in extraction solvent 
delivery ``i.''
Total Received = Total gallons of extraction solvent received since the 
end of the previous operating month.
n = Number of extraction solvent deliveries since the end of the 
previous operating month.

    (3) Determine the volume fraction of HAP in your extraction solvent 
as a 12 operating months weighted average. When your source has 
processed oilseed for 12 operating months, sum the products of the 
monthly weighted average HAP volume fraction and corresponding volume of 
solvent received, and divide the sum by the total volume of solvent 
received for the 12 operating months, as expressed by Equation 2 of this 
section. Record the result by the end of each calendar month following

[[Page 217]]

an operating month and use it in Equation 2 of Sec. 63.2840 to determine 
the compliance ratio. Equation 2 of this section follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.005

Where:

Receivedi = Gallons of extraction solvent received in 
operating month ``i'' as determined in accordance with 
Sec. 63.2853(a)(4).
Contenti = Average volume fraction of HAP in extraction 
solvent received in operating month ``i'' as determined in accordance 
with paragraph (b)(1) of this section.
Total Received = Total gallons of extraction solvent received during the 
previous 12 operating months.



Sec. 63.2855  How do I determine the quantity of oilseed processed?

    All oilseed measurements must be determined on an as received basis, 
as defined in Sec. 63.2872. The as received basis refers to the oilseed 
chemical and physical characteristics as initially received by the 
source and prior to any oilseed handling and processing. By the end of 
each calendar month following an operating month, you must determine the 
tons as received of each listed oilseed processed for the operating 
month. The total oilseed processed for an operating month includes the 
total of each oilseed processed during all normal operating periods that 
occur within the operating month. If you have determined the tons of 
oilseed processed for 12 or more operating months, then you must also 
determine the 12 operating months rolling sum of each type oilseed 
processed by summing the tons of each type of oilseed processed for the 
previous 12 operating months. The 12 operating months rolling sum of 
each type of oilseed processed is used to calculate the compliance ratio 
as described in Sec. 63.2840.
    (a) To determine the tons as received of each type of oilseed 
processed at your source, follow the procedures in your plan for 
demonstrating compliance to determine the items in paragraphs (a)(1) 
through (5) of this section:
    (1) The dates that define each operating status period. The dates 
that define each operating status period include the beginning date of 
each calendar month and the date of any change in the source operating 
status. If, prior to the effective date of this rule, your source 
determines the oilseed inventory on an accounting month rather than a 
calendar month basis, and you have 12 complete accounting months of 
approximately equal duration in a calendar year, you may substitute the 
accounting month time interval for the calendar month time interval. If 
you choose to use an accounting month rather than a calendar month, you 
must document this measurement frequency selection in your plan for 
demonstrating compliance, and you must remain on this schedule unless 
you request and receive written approval from the agency responsible for 
these NESHAP. The dates on each oilseed inventory log must be consistent 
with the dates recorded for the solvent inventory.
    (2) Source operating status. You must categorize the source 
operation for each recorded time interval. The source operating status 
for each time interval recorded on the oilseed inventory for each type 
of oilseed must be consistent with the operating status recorded on the 
solvent inventory logs as described in Sec. 63.2853(a)(2).
    (3) Measuring the beginning and ending inventory for each oilseed. 
You are required to measure and record the oilseed inventory on the 
beginning and ending dates of each normal operating period that occurs 
during an operating month. An operating month is any calendar month with 
at least one normal

[[Page 218]]

operating period. You must consistently follow the procedures described 
in your plan for demonstrating compliance, as specified in Sec. 63.2851, 
to determine the oilseed inventory on an as received basis and maintain 
readily available records of the oilseed inventory as described by 
Sec. 63.2862(c)(3).
    (4) Tons of each oilseed received. Record the type of oilseed and 
tons of each shipment of oilseed received and added to your on-site 
storage.
    (5) Oilseed inventory adjustments. In some situations, determining 
the quantity of oilseed processed directly from the measured oilseed 
inventory and quantity of oilseed received is not an accurate estimate 
of the tons of oilseed processed for use in determining compliance 
ratios. For example, spoiled and molded oilseed removed from storage but 
not processed by your source will result in an overestimate of the 
quantity of oilseed processed. In such cases, you must adjust the 
oilseed inventory and provide a justification for the adjustment. 
Situations that may require oilseed inventory adjustments include, but 
are not limited to, the situations listed in paragraphs (a)(5)(i) 
through (v) of this section:
    (i) Oilseed that mold or otherwise become unsuitable for processing.
    (ii) Oilseed you sell before it enters the processing operation.
    (iii) Oilseed destroyed by an event such as a process malfunction, 
fire, or natural disaster.
    (iv) Oilseed processed through operations prior to solvent 
extraction such as screening, dehulling, cracking, drying, and 
conditioning; but that are not routed to the solvent extractor for 
further processing.
    (v) Periodic physical measurements of inventory. For example, some 
sources periodically empty oilseed storage silos to physically measure 
the current oilseed inventory. This periodic measurement procedure 
typically results in a small inventory correction. The correction 
factor, usually less than 1 percent, may be used to make an adjustment 
to the source's oilseed inventory that was estimated previously with 
indirect measurement techniques. To make this adjustment, your plan for 
demonstrating compliance must provide for such an adjustment.
    (b) Use Equation 1 of this section to determine the quantity of each 
oilseed type processed at your affected source during normal operating 
periods recorded within a calendar month. Equation 1 of this section 
follows:
[GRAPHIC] [TIFF OMITTED] TR12AP01.000

Where:

SEEDB = Tons of oilseed in the inventory at the beginning of 
normal operating period ``i'' as determined in accordance with paragraph 
(a)(3) of this section.
SEEDE = Tons of oilseed in the inventory at the end of normal 
operating period ``i'' as determined in accordance with paragraph (a)(3) 
of this section.
SEEDR = Tons of oilseed received during normal operating 
period ``i'' as determined in accordance with paragraph (a)(4) of this 
section.
SEEDA = Tons of oilseed added or removed from the oilseed 
inventory during normal operating period ``i'' as determined in 
accordance with paragraph (a)(5) of this section.
n = Number of normal operating periods in the calendar month during 
which this type oilseed was processed.

    (c) The quantity of each oilseed processed is the total tons of each 
type of listed oilseed processed during normal operating periods in the 
previous 12 operating months. You determine the tons of each oilseed 
processed by summing the monthly quantity of each oilseed processed for 
the previous 12 operating months. You must record the 12 operating 
months quantity of each type of oilseed processed by the end of

[[Page 219]]

each calendar month following an operating month. Use the 12 operating 
months quantity of each type of oilseed processed to determine the 
compliance ratio as described in Sec. 63.2840. The quantity of oilseed 
processed does not include oilseed processed during the operating status 
periods in paragraphs (c)(1) through (4) of this section:
    (1) Nonoperating periods as described in Sec. 63.2853 (a)(2)(ii).
    (2) Initial startup periods as described in Sec. 63.2850(c)(2) or 
(d)(2).
    (3) Malfunction periods as described in Sec. 63.2850(e)(2).
    (4) Exempt operation periods as described in Sec. 63.2853 (a)(2)(v).
    (5) If any one of these four operating status periods span an entire 
calendar month, then the calendar month is treated as a nonoperating 
month and there is no compliance ratio determination.

                   Notifications, Reports, and Records



Sec. 63.2860  What notifications must I submit and when?

    You must submit the one-time notifications listed in paragraphs (a) 
through (d) of this section to the responsible agency:
    (a) Initial notification for existing sources. For an existing 
source, submit an initial notification to the agency responsible for 
these NESHAP no later than 120 days after the effective date of this 
subpart. In the notification, include the items in paragraphs (a)(1) 
through (5) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Identification of the relevant standard, such as the vegetable 
oil production NESHAP, and compliance date.
    (4) A brief description of the source including the types of listed 
oilseeds processed, nominal operating capacity, and type of 
desolventizer(s) used.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source meets the definition of an area source. An 
area source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (b) Initial notifications for new and reconstructed sources. New or 
reconstructed sources must submit a series of notifications before, 
during, and after source construction per the schedule listed in 
Sec. 63.9. The information requirements for the notifications are the 
same as those listed in the General Provisions with the exceptions 
listed in paragraphs (b)(1) and (2) of this section:
    (1) The application for approval of construction does not require 
the specific HAP emission data required in Sec. 63.5(d)(1)(ii)(H) and 
(iii), (d)(2) and (d)(3)(ii). The application for approval of 
construction would include, instead, a brief description of the source 
including the types of listed oilseeds processed, nominal operating 
capacity, and type of desolventizer(s) used.
    (2) The notification of actual startup date must also include 
whether you have elected to operate under an initial startup period 
subject to Sec. 63.2850(c)(2) and provide an estimate and justification 
for the anticipated duration of the initial startup period.
    (c) Significant modification notifications. Any existing or new 
source that plans to undergo a significant modification as defined in 
Sec. 63.2872 must submit two reports as described in paragraphs (c)(1) 
and (2) of this section:
    (1) Initial notification. You must submit an initial notification to 
the agency responsible for these NESHAP 30 days prior to initial startup 
of the significantly modified source. The initial notification must 
demonstrate that the proposed changes qualify as a significant 
modification. The initial notification must include the items in 
paragraphs (c)(1)(i) and (ii) of this section:
    (i) The expected startup date of the modified source.
    (ii) A description of the significant modification including a list 
of the equipment that will be replaced or modified. If the significant 
modification involves changes other than adding or replacing extractors, 
desolventizer-toasters (conventional and specialty), and meal dryer-
coolers, then you must also include the fixed capital cost of the new 
components, expressed as a percentage of the fixed capital cost to build 
a comparable new

[[Page 220]]

vegetable oil production process; supporting documentation for the cost 
estimate; and documentation that the proposed changes will significantly 
affect solvent losses.
    (2) Notification of actual startup. You must submit a notification 
of actual startup date within 15 days after initial startup of the 
modified source. The notification must include the items in paragraphs 
(c)(2)(i) through (iv) of this section:
    (i) The initial startup date of the modified source.
    (ii) An indication whether you have elected to operate under an 
initial startup period subject to Sec. 63.2850(d)(2).
    (iii) The anticipated duration of any initial startup period.
    (iv) A justification for the anticipated duration of any initial 
startup period.
    (d) Notification of compliance status. As an existing, new, or 
reconstructed source, you must submit a notification of compliance 
status report to the responsible agency no later than 60 days after 
determining your initial 12 operating months compliance ratio. If you 
are an existing source, you generally must submit this notification no 
later than 50 calendar months after the effective date of these NESHAP 
(36 calendar months for compliance, 12 operating months to record data, 
and 2 calendar months to complete the report). If you are a new or 
reconstructed source, the notification of compliance status is generally 
due no later than 20 calendar months after initial startup (6 calendar 
months for the initial startup period, 12 operating months to record 
data, and 2 calendar months to complete the report). The notification of 
compliance status must contain the items in paragraphs (d)(1) through 
(6) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Each listed oilseed type processed during the previous 12 
operating months.
    (4) Each HAP identified under Sec. 63.2854(a) as being present in 
concentrations greater than 1 percent by volume in each delivery of 
solvent received during the 12 operating months period used for the 
initial compliance determination.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source qualifies as an area source. An area 
source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (6) A compliance certification indicating whether the source 
complied with all of the requirements of this subpart throughout the 12 
operating months used for the initial source compliance determination. 
This certification must include a certification of the items in 
paragraphs (d)(6)(i) through (iii) of this section:
    (i) The plan for demonstrating compliance (as described in 
Sec. 63.2851) and SSM plan (as described in Sec. 63.2852) are complete 
and available on-site for inspection.
    (ii) You are following the procedures described in the plan for 
demonstrating compliance.
    (iii) The compliance ratio is less than or equal to 1.00.



Sec. 63.2861  What reports must I submit and when?

    After the initial notifications, you must submit the reports in 
paragraphs (a) through (d) of this section to the agency responsible for 
these NESHAP at the appropriate time intervals:
    (a) Annual compliance certifications. The first annual compliance 
certification is due 12 calendar months after you submit the 
notification of compliance status. Each subsequent annual compliance 
certification is due 12 calendar months after the previous annual 
compliance certification. The annual compliance certification provides 
the compliance status for each operating month during the 12 calendar 
months period ending 60 days prior to the date on which the report is 
due. Include the information in paragraphs (a)(1) through (6) of this 
section in the annual certification:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.

[[Page 221]]

    (3) Each listed oilseed type processed during the 12 calendar months 
period covered by the report.
    (4) Each HAP identified under Sec. 63.2854(a) as being present in 
concentrations greater than 1 percent by volume in each delivery of 
solvent received during the 12 calendar months period covered by the 
report.
    (5) A statement designating the source as a major source of HAP or a 
demonstration that the source qualifies as an area source. An area 
source is a source that is not a major source and is not collocated 
within a plant site with other sources that are individually or 
collectively a major source.
    (6) A compliance certification to indicate whether the source was in 
compliance for each compliance determination made during the 12 calendar 
months period covered by the report. For each such compliance 
determination, you must include a certification of the items in 
paragraphs (a)(6)(i) through (ii) of this section:
    (i) You are following the procedures described in the plan for 
demonstrating compliance.
    (ii) The compliance ratio is less than or equal to 1.00.
    (b) Deviation notification report. Submit a deviation report for 
each compliance determination you make in which the compliance ratio 
exceeds 1.00 as determined under Sec. 63.2840(c). Submit the deviation 
report by the end of the month following the calendar month in which you 
determined the deviation. The deviation notification report must include 
the items in paragraphs (b)(1) through (4) of this section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the vegetable oil production process.
    (3) Each listed oilseed type processed during the 12 operating 
months period for which you determined the deviation.
    (4) The compliance ratio comprising the deviation. You may reduce 
the frequency of submittal of the deviation notification report if the 
agency responsible for these NESHAP does not object as provided in 
Sec. 63.10(e)(3)(iii).
    (c) Periodic startup, shutdown, and malfunction report. If you 
choose to operate your source under an initial startup period subject to 
Sec. 63.2850(c)(2) or (d)(2) or a malfunction period subject to 
Sec. 63.2850(e)(2), you must submit a periodic SSM report by the end of 
the calendar month following each month in which the initial startup 
period or malfunction period occurred. The periodic SSM report must 
include the items in paragraphs (c)(1) through (3) of this section:
    (1) The name, title, and signature of a source's responsible 
official who is certifying that the report accurately states that all 
actions taken during the initial startup or malfunction period were 
consistent with the SSM plan.
    (2) A description of events occurring during the time period, the 
date and duration of the events, and reason the time interval qualifies 
as an initial startup period or malfunction period.
    (3) An estimate of the solvent loss during the initial startup or 
malfunction period with supporting documentation.
    (d) Immediate SSM reports. If you handle a SSM during an initial 
startup period subject to Sec. 63.2850(c)(2) or (d)(2) or a malfunction 
period subject to Sec. 63.2850(e)(2) differently from procedures in the 
SSM plan and the relevant emission requirements in Sec. 63.2840 are 
exceeded, then you must submit an immediate SSM report. Immediate SSM 
reports consist of a telephone call or facsimile transmission to the 
responsible agency within 2 working days after starting actions 
inconsistent with the SSM plan, followed by a letter within 7 working 
days after the end of the event. The letter must include the items in 
paragraphs (d)(1) through (3) of this section:
    (1) The name, title, and signature of a source's responsible 
official who is certifying the accuracy of the report, an explanation of 
the event, and the reasons for not following the SSM plan.
    (2) A description and date of the SSM event, its duration, and 
reason it qualifies as a SSM.
    (3) An estimate of the solvent loss for the duration of the SSM 
event with supporting documentation.

Sec. 63.2862  What records must I keep?

    (a) You must satisfy the recordkeeping requirements of this section 
by the compliance date for your source specified in Table 1 of 
Sec. 63.2834.
    (b) Prepare a plan for demonstrating compliance (as described in 
Sec. 63.2851) and a SSM plan (as described in Sec. 63.2852). In these 
two plans, describe the procedures you will follow in obtaining and 
recording data, and determining compliance under normal operations or a 
SSM subject to the Sec. 63.2850(c)(2) or (d)(2) initial startup period 
or the Sec. 63.2850(e)(2) malfunction period. Complete both plans before 
the compliance date for your source and keep them on-site and readily 
available as long as the source is operational.
    (c) If your source processes any listed oilseed, record the items in 
paragraphs (c)(1) through (5) of this section:
    (1) For the solvent inventory, record the information in paragraphs 
(c)(1)(i) through (vii) of this section in accordance with your plan for 
demonstrating compliance:
    (i) Dates that define each operating status period during a calendar 
month.
    (ii) The operating status of your source such as normal operation, 
nonoperating, initial startup period, malfunction period, or exempt 
operation for each recorded time interval.
    (iii) Record the gallons of extraction solvent in the inventory on 
the beginning and ending dates of each normal operating period.
    (iv) The gallons of all extraction solvent received, purchased, and 
recovered during each calendar month.
    (v) All extraction solvent inventory adjustments, additions or 
subtractions. You must document the reason for the adjustment and 
justify the quantity of the adjustment.
    (vi) The total solvent loss for each calendar month, regardless of 
the source operating status.
    (vii) The actual solvent loss in gallons for each operating month.
    (2) For the weighted average volume fraction of HAP in the 
extraction solvent, you must record the items in paragraphs (c)(2)(i) 
through (iii) of this section:
    (i) The gallons of extraction solvent received in each delivery.
    (ii) The volume fraction of each HAP exceeding 1 percent by volume 
in each delivery of extraction solvent.
    (iii) The weighted average volume fraction of HAP in extraction 
solvent received since the end of the last operating month as determined 
in accordance with Sec. 63.2854(b)(2).
    (3) For each type of listed oilseed processed, record the items in 
paragraphs (c)(3)(i) through (vi) of this section, in accordance with 
your plan for demonstrating compliance:
    (i) The dates that define each operating status period. These dates 
must be the same as the dates entered for the extraction solvent 
inventory.
    (ii) The operating status of your source such as normal operation, 
nonoperating, initial startup period, malfunction period, or exempt 
operation for each recorded time interval. On the log for each type of 
listed oilseed that is not being processed during a normal operating 
period, you must record which type of listed oilseed is being processed 
in addition to the source operating status.
    (iii) The oilseed inventory for the type of listed oilseed being 
processed on the beginning and ending dates of each normal operating 
period.
    (iv) The tons of each type of listed oilseed received at the 
affected source each normal operating period.
    (v) All listed oilseed inventory adjustments, additions or 
subtractions for normal operating periods. You must document the reason 
for the adjustment and justify the quantity of the adjustment.
    (vi) The tons of each type of listed oilseed processed during each 
operating month.
    (d) After your source has processed listed oilseed for 12 operating 
months, and you are not operating during an initial startup period as 
described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction period as 
described in Sec. 63.2850(e)(2), record the items in paragraphs (d)(1) 
through (5) of this section by the end of the calendar month following 
each operating month:
    (1) The 12 operating months rolling sum of the actual solvent loss 
in gallons as described in Sec. 63.2853(c).
    (2) The weighted average volume fraction of HAP in extraction 
solvent

[[Page 223]]

received for the previous 12 operating months as described in 
Sec. 63.2854(b)(3).
    (3) The 12 operating months rolling sum of each type of listed 
oilseed processed at the affected source in tons as described in 
Sec. 63.2855(c).
    (4) A determination of the compliance ratio. Using the values from 
Secs. 63.2853, 63.2854, 63.2855, and Table 1 of Sec. 63.2840, calculate 
the compliance ratio using Equation 2 of Sec. 63.2840.
    (5) A statement of whether the source is in compliance with all of 
the requirements of this subpart. This includes a determination of 
whether you have met all of the applicable requirements in Sec. 63.2850.
    (e) For each SSM event subject to an initial startup period as 
described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction period as 
described in Sec. 63.2850(e)(2), record the items in paragraphs (e)(1) 
through (3) of this section by the end of the calendar month following 
each month in which the initial startup period or malfunction period 
occurred:
    (1) A description and date of the SSM event, its duration, and 
reason it qualifies as an initial startup or malfunction.
    (2) An estimate of the solvent loss in gallons for the duration of 
the initial startup or malfunction period with supporting documentation.
    (3) A checklist or other mechanism to indicate whether the SSM plan 
was followed during the initial startup or malfunction period.



Sec. 63.2863  In what form and how long must I keep my records?

    (a) Your records must be in a form suitable and readily available 
for review in accordance with Sec. 63.10(b)(1).
    (b) As specified in Sec. 63.10(b)(1), you must keep each record for 
5 years following the date of each occurrence, measurement, maintenance, 
corrective action, report, or record.
    (c) You must keep each record on-site for at least 2 years after the 
date of each occurrence, measurement, maintenance, corrective action, 
report, or record, in accordance with Sec. 3.10(b)(1). You can keep the

Sec. 63.2871  Who implements and enforces this subpart?

    (a) This subpart can be implemented by us, the U.S. EPA, or a 
delegated authority such as your State, local, or tribal agency. If the 
U.S. EPA Administrator has delegated authority to your State, local, or 
tribal agency, then that agency, as well as the U.S. EPA, has the 
authority to implement and enforce this subpart. You should contact your 
U.S. EPA Regional Office to find out if this subpart is delegated to 
your State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under section 40 CFR part 
63, subpart E, the authorities contained in paragraph (c) of this 
section are retained by the Administrator of the U.S. EPA and are not 
transferred to the State, local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are as follows:
    (1) Approval of alternative nonopacity emissions standards under 
Sec. 63.6(g).
    (2) Approval of alternative opacity standards under Sec. 63.6(h)(9).
    (3) Approval of major alternatives to test methods under 
Sec. 63.7(e)(2)(ii) and (f) and as defined in Sec. 63.90.
    (4) Approval of major alternatives to monitoring under Sec. 63.8(f) 
and as defined in Sec. 63.90.
    (5) Approval of major alternatives to recordkeeping and reporting 
under Sec. 63.10(f) and as defined in Sec. 63.90.



Sec. 63.2872  What definitions apply to this subpart?

    Terms used in this subpart are defined in the sources listed:
    (a) The Clean Air Act, section 112(a).
    (b) In 40 CFR 63.2, the NESHAP General Provisions.
    (c) In this section as follows:
    Accounting month means a time interval defined by a business firm 
during which corporate economic and financial factors are determined on 
a consistent and regular basis. An accounting month will consist of 
approximately 4 to 5 calendar weeks and each accounting month will be of 
approximate equal duration. An accounting month may not correspond 
exactly to a calendar month, but 12 accounting months will correspond 
exactly to a calendar year.
    Actual solvent loss means the gallons of solvent lost from a source 
during 12 operating months as determined in accordance with 
Sec. 63.2853.
    Agricultural product means any commercially grown plant or plant 
product.
    Allowable HAP loss means the gallons of HAP that would have been 
lost from a source if the source was operating at the solvent loss 
factor for each listed oilseed type. The allowable HAP loss in gallons 
is determined by multiplying the tons of each oilseed type processed 
during the previous 12 operating months, as determined in accordance 
with Sec. 63.2855, by the corresponding oilseed solvent loss factor 
(gal/ton) listed in Table 1 of Sec. 63.2840, and by the dimensionless 
constant 0.64, and summing the result for all oilseed types processed.
    Area source means any source that does not meet the major source 
definition.
    As received is the basis upon which all oilseed measurements must be 
determined and refers to the oilseed chemical and physical 
characteristics as initially received by the source and prior to any 
oilseed handling and processing.
    Batch operation means any process that operates in a manner where 
the

[[Page 227]]

addition of raw material and withdrawal of product do not occur 
simultaneously. Typically, raw material is added to a process, 
operational steps occur, and a product is removed from the process. More 
raw material is then added to the process and the cycle repeats.
    Calendar month means 1 month as specified in a calendar.
    Compliance date means the date on which monthly compliance 
recordkeeping begins. For existing sources, recordkeeping typically 
begins 3 years after the effective date of the subpart. For new and 
reconstructed sources, recordkeeping typically begins upon initial 
startup, except as noted in Sec. 63.2834.
    Compliance ratio means a ratio of the actual HAP loss in gallons 
from the previous 12 operating months to an allowable HAP loss in 
gallons, which is determined by using oilseed solvent loss factors in 
Table 1 of Sec. 63.2840, the weighted average volume fraction of HAP in 
solvent received for the previous 12 operating months, and the tons of 
each type of listed oilseed processed in the previous 12 operating 
months. Months during which no listed oilseed is processed, or months 
during which the Sec. 63.2850(c)(2) or (d)(2) initial startup period or 
the Sec. 63.2850(e)(2) malfunction period applies, are excluded from 
this calculation. Equation 2 of Sec. 63.2840 is used to calculate this 
value. If the value is less than or equal to 1.00, the source is in 
compliance. If the value is greater than 1.00, the source is deviating 
from compliance.
    Continuous operation means any process that adds raw material and 
withdraws product simultaneously. Mass, temperature, concentration and 
other properties typically approach steady-state conditions.
    Conventional desolventizer means a desolventizer toaster that 
operates with indirect and direct-contact steam to remove solvent from 
the extracted meal. Oilseeds processed in a conventional desolventizer 
produce crude vegetable oil and crude meal products, such as animal 
feed.
    Corn germ dry milling means a source that processes corn germ that 
has been separated from the other corn components using a ``dry'' 
process of mechanical chafing and air sifting.
    Corn germ wet milling means a source that processes corn germ that 
has been separated from other corn components using a ``wet'' process of 
centrifuging a slurry steeped in a dilute sulfurous acid solution.
    Exempt period means a period of time during which a source processes 
agricultural products not defined as listed oilseed.
    Extraction solvent means an organic chemical medium used to remove 
oil from an oilseed. Typically, the extraction solvent is a commercial 
grade of hexane isomers which have an approximate HAP content of 64 
percent by volume.
    Hazardous air pollutant (HAP) means any substance or mixture of 
substances listed as a hazardous air pollutant under section 112(b) of 
the Clean Air Act, as of April 12, 2001.
    Initial startup date means the first calendar day that a new, 
reconstructed or significantly modified source processes any listed 
oilseed.
    Initial startup period means a period of time from the initial 
startup date of a new, reconstructed or significantly modified source, 
for which you choose to operate the source under an initial startup 
period subject to Sec. 63.2850(c)(2) or (d)(2). During an initial 
startup period, a source is in compliance with the standards by 
following the operating and maintenance procedures listed for minimizing 
HAP emissions in the source's SSM plan rather than being subject to a 
HAP emission limit. The initial startup period following initial startup 
of a new or reconstructed source may not exceed 6 calendar months. The 
initial startup period following a significant modification may not 
exceed 3 calendar months. Solvent and oilseed inventory information 
recorded during the initial startup period is excluded from use in any 
compliance ratio determinations.
    Large cottonseed plant means a vegetable oil production process that 
processes 120,000 tons or more of cottonseed and other listed oilseed 
during all normal operating periods in a 12 operating months period used 
to determine compliance.

[[Page 228]]

    Malfunction period means a period of time between the beginning and 
end of a process malfunction and the time reasonably necessary for a 
source to correct the malfunction for which you choose to operate the 
source under a malfunction period subject to Sec. 63.2850(e)(2). This 
period may include the duration of an unscheduled process shutdown, 
continued operation during a malfunction, or the subsequent process 
startup after a shutdown resulting from a malfunction. During a 
malfunction period, a source complies with the standards by following 
the operating and maintenance procedures described for minimizing HAP 
emissions in the source's SSM plan rather than being subject to a HAP 
emission limit. Therefore, solvent and oilseed inventory information 
recorded during a malfunction period is excluded from use in any 
compliance ratio determinations.
    Mechanical extraction means removing vegetable oil from oilseeds 
using only mechanical devices such as presses or screws that physically 
force the oil from the oilseed. Mechanical extraction techniques use no 
organic solvents to remove oil from an oilseed.
    Nonoperating period means any period of time in which a source 
processes no agricultural product. This operating status does not apply 
during any period in which the source operates under an initial startup 
period as described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction 
period, as described in Sec. 63.2850(e)(2).
    Normal operating period means any period of time in which a source 
processes a listed oilseed that is not categorized as an initial startup 
period as described in Sec. 63.2850(c)(2) or (d)(2), or a malfunction 
period, as described in Sec. 63.2850(e)(2). At the beginning and ending 
dates of a normal operating period, solvent and oilseed inventory 
information is recorded and included in the compliance ratio 
determination.
    Oilseed or listed oilseed means the following agricultural products: 
corn germ, cottonseed, flax, peanut, rapeseed (for example, canola), 
safflower, soybean, and sunflower.
    Oilseed solvent loss factor means a ratio expressed as gallons of 
solvent loss per ton of oilseed processed. The solvent loss factors are 
presented in Table 1 of Sec. 63.2840 and are used to determine the 
allowable HAP loss.
    Operating month means any calendar or accounting month in which a 
source processes any quantity of listed oilseed, excluding any entire 
calendar or accounting month in which the source operated under an 
initial startup period as described in Sec. 63.2850(c)(2) or (d)(2), or 
a malfunction period as described in Sec. 63.2850(e)(2). An operating 
month may include time intervals characterized by several types of 
operating status. However, an operating month must have at least one 
normal operating period.
    Significant modification means the addition of new equipment or the 
modification of existing equipment that:
    (1) Significantly affects solvent losses from your vegetable oil 
production process;
    (2) The fixed capital cost of the new components represents a 
significant percentage of the fixed capital cost of building a 
comparable new vegetable oil production process;
    (3) The fixed capital cost of the new equipment does not constitute 
reconstruction as defined in Sec. 63.2; and
    (4) Examples of significant modifications include replacement of or 
major changes to solvent recovery equipment such as extractors, 
desolventizer-toasters/dryer-coolers, flash desolventizers, and 
distillation equipment associated with the mineral oil system, and 
equipment affecting desolventizing efficiency and steady-state operation 
of your vegetable oil production process such as flaking mills, oilseed 
heating and conditioning equipment, and cracking mills.
    Small cottonseed plant means a vegetable oil production process that 
processes less than 120,000 tons of cottonseed and other listed oilseed 
during all normal operating periods in a 12 operating months period used 
to determine compliance.
    Solvent extraction means removing vegetable oil from listed oilseed 
using an organic solvent in a direct-contact system.
    Solvent working capacity means the volume of extraction solvent 
normally retained in solvent recovery equipment. Examples include 
components such as the solvent extractor,

[[Page 229]]

desolventizer-toaster, solvent storage and working tanks, mineral oil 
absorption system, condensers, and oil/solvent distillation system.
    Specialty desolventizer means a desolventizer that removes excess 
solvent from soybean meal using vacuum conditions, energy from 
superheated solvent vapors, or reduced operating conditions (e.g., 
temperature) as compared to the typical operation of a conventional 
desolventizer. Soybeans processed in a specialty desolventizer result in 
high-protein vegetable meal products for human and animal consumption, 
such as calf milk replacement products and meat extender products.
    Vegetable oil production process means the equipment comprising a 
continuous process for producing crude vegetable oil and meal products, 
including specialty soybean products, in which oil is removed from 
listed oilseeds through direct contact with an organic solvent. Process 
equipment typically includes the following components: oilseed 
preparation operations (including conditioning, drying, dehulling, and 
cracking), solvent extractors, desolventizer-toasters, meal dryers, meal 
coolers, meal conveyor systems, oil distillation units, solvent 
evaporators and condensers, solvent recovery system (also referred to as 
a mineral oil absorption system), vessels storing solvent-laden 
materials, and crude meal packaging and storage vessels. A vegetable oil 
production process does not include vegetable oil refining operations 
(including operations such as bleaching, hydrogenation, and deodorizing) 
and operations that engage in additional chemical treatment of crude 
soybean meals produced in specialty desolventizer units (including 
operations such as soybean isolate production).

    Source: 67 FR 17835, Apr. 11, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.2980  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for emissions from facilities that produce wet-
formed fiberglass mat. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the emission 
limitations.



Sec. 63.2981  Does this subpart apply to me?

    You must comply with this subpart if you meet the criteria in 
paragraphs (a) and (b) of this section:
    (a) You own or operate a drying and curing oven at a wet-formed 
fiberglass mat production facility.
    (b) Your drying and curing oven or the facility at which your drying 
and curing oven is located is a major source of hazardous air pollutants 
(HAP). A major source is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or can potentially emit, considering controls, in the aggregate, 
9.07 megagrams (10 tons) or more per year of a single HAP or 22.68 
megagrams (25 tons) or more per year of any combination of HAP.



Sec. 63.2982  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source. The affected source (the portion of your plant covered 
by this subpart) is each wet-formed fiberglass mat drying and curing 
oven.
    (b) An affected source is a new affected source if you commenced 
construction of the affected source after May 26, 2000, and you meet the 
applicability criteria in Sec. 63.2981 at start-up.
    (c) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (d) An affected source is existing if it is not new or 
reconstructed.

                          Emission Limitations



Sec. 63.2983  What emission limits must I meet?

    (a) You must limit the formaldehyde emissions from each drying and 
curing oven by either:
    (1) Limiting emissions of formaldehyde to 0.03 kilograms or less per 
megagram (0.05 pounds per ton) of fiberglass mat produced; or
    (2) Reducing uncontrolled formaldehyde emissions by 96 percent or 
more.
    (b) [Reserved]



Sec. 63.2984  What operating limits must I meet?

    (a) You must maintain operating parameters within established limits 
or ranges specified in your operation, maintenance, and monitoring (OMM) 
plan described in Sec. 63.2987. If there is a deviation of any of the 
specified parameters from the limit or range specified in the OMM plan, 
you must address the deviation according to paragraph (b) of this 
section. You must comply with the operating limits specified in 
paragraphs (a)(1) through (4) of this section:
    (1) You must operate the thermal oxidizer so that the average 
operating temperature in any 3-hour block period does not fall below the 
temperature established during your performance test and specified in 
your OMM plan.
    (2) You must not use a resin with a free-formaldehyde content 
greater than that of the resin used during your performance test and 
specified in your OMM plan.
    (3) You must operate the wet-formed fiberglass mat production 
process so that the average urea formaldehyde resin solids application 
rate in any 3-hour block period does not exceed the average application 
rate achieved during your performance test and specified in your OMM 
plan.
    (4) If you use an add-on control device other than a thermal 
oxidizer or wish to monitor an alternative parameter and comply with a 
different operating limit, you must obtain approval for the alternative 
monitoring under Sec. 63.8(f). You must include the approved alternative 
monitoring and operating limits in the OMM plan specified in 
Sec. 63.2987.
    (b) When during a period of normal operations you detect that an 
operating parameter deviates from the limit or range established in 
paragraph (a) of this section, you must initiate corrective actions 
within 1 hour according to the provisions of your OMM plan. During 
periods of start up, shut down, or malfunction you must follow your 
start up, shut down and malfunction plan (SSMP). The corrective action 
actions must be completed in an expeditious manner as specified in the 
OMM plan or SSMP.
    (c) You must maintain and inspect control devices according to the 
procedures specified in the OMM plan.
    (d) You must include the operating limits specified in paragraphs 
(a)(1) through (4) of this section and their allowable ranges or levels 
in your OMM plan. Your 40 CFR part 70 operating permit for the drying 
and curing oven must contain a requirement that you develop and operate 
according to an OMM plan at all times.
    (e) If you use a thermal oxidizer or other control device to achieve 
the emission limits in Sec. 63.2983, you must capture and convey the 
formaldehyde emissions from each drying and curing oven according to the 
procedures in chapters 3 and 5 of ``Industrial Ventilation: A Manual of 
Recommended Practice'' (23rd Edition). This publication is incorporated 
by reference in Sec. 63.3003.



Sec. 63.2985  When do I have to comply with these standards?

    (a) Existing drying and curing ovens must be in compliance with this 
subpart no later than April 11, 2005.
    (b) New or reconstructed drying and curing ovens must be in 
compliance with this subpart at startup or by April 11, 2002, whichever 
is later.
    (c) If your facility is an area source that increases its emissions 
or its potential to emit such that it becomes a major source of 
hazardous air pollutants, the following apply:
    (1) Any portion of the existing facility that is a new affected 
source or a new reconstructed affected source must be in compliance upon 
startup.
    (2) All other parts of the source must be in compliance with this 
subpart 1 year after becoming a major source or by April 11, 2005, 
whichever is later.

[[Page 231]]



Sec. 63.2986  How do I comply with the standards?

    (a) You must install, maintain, and operate a thermal oxidizer or 
other control device or implement a process modification that reduces 
formaldehyde emissions from each drying and curing oven to the emission 
limits specified in Sec. 63.2983.
    (b) You must comply with the operating limits specified in 
Sec. 63.2984. The operating limits prescribe the requirements for 
demonstrating continuous compliance based on the OMM plan. You must 
begin complying with the operating limits on the date by which you must 
complete the initial performance test.
    (c) You must conduct a performance test according to Secs. 63.2991, 
63.2992, and 63.2993 to demonstrate compliance for each drying and 
curing oven subject to the emission limits in Sec. 63.2983, and to 
establish or modify the operating limits or ranges for process or 
control device parameters that will be monitored to demonstrate 
continuous compliance.
    (d) You must install, calibrate, maintain, and operate devices that 
monitor the parameters specified in your OMM plan at the frequency 
specified in the plan. All continuous parameter monitoring systems must 
be installed and operating no later than the applicable compliance date 
specified in Sec. 63.2985.
    (e) You must prepare and follow a written OMM plan as specified in 
Sec. 63.2987.
    (f) You must comply with the monitoring, recordkeeping,

    (g) You must comply with the requirements in paragraphs (g)(1) 
through (3) of this section.
    (1) You must be in compliance with the emission limits in 
Sec. 63.2983 and the operating limits in Sec. 63.2984 at all times, 
except during periods of startup, shutdown, or malfunction.
    (2) 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).
    (3) You must develop and implement a written SSMP according to the 
provisions in Sec. 63.6(e)(3). The SSMP must address the startup, 
shutdown, and corrective actions taken for malfunctioning process and 
air pollution control equipment.

               Operation, Maintenance, and Monitoring Plan



Sec. 63.2987  What must my operation, maintenance, and monitoring (OMM) plan include?

    (a) You must prescribe the monitoring that will be performed to 
ensure compliance with these emission limitations. Minimum monitoring 
requirements are listed in table 1 of this subpart. Your plan must 
specify the items listed in paragraphs (a)(1) through (3) of this 
section:
    (1) Each process and control device to be monitored, the type of 
monitoring device that will be used, and the operating parameters that 
will be monitored.
    (2) A monitoring schedule that specifies the frequency that the 
parameter values will be determined and recorded.
    (3) The operating limits or ranges for each parameter that represent 
continuous compliance with the emission limits in Sec. 63.2983. 
Operating limits and ranges must be based on values of the monitored 
parameters recorded during performance tests.
    (b) You must establish routine and long-term maintenance and 
inspection schedules for each control device. You must incorporate in 
the schedules the control device manufacturer's recommendations for 
maintenance and inspections or equivalent procedures. If you use a 
thermal oxidizer, the maintenance schedule must include procedures for 
annual or more frequent inspection of the thermal oxidizer to ensure 
that the structural and design integrity of the combustion chamber is 
maintained. At a minimum, you must meet the requirements of paragraphs 
(b)(1) through (10) of this section:
    (1) Inspect all burners, pilot assemblies, and pilot sensing devices 
for proper operation. Clean pilot sensor if necessary.
    (2) Ensure proper adjustment of combustion air and adjust if 
necessary.
    (3) Inspect, when possible, all internal structures (such as 
baffles) to ensure structural integrity per the design specifications.

[[Page 232]]

    (4) Inspect dampers, fans, and blowers for proper operation.
    (5) Inspect motors for proper operation.
    (6) Inspect, when possible, combustion chamber refractory lining. 
Clean and repair or replace lining if necessary.
    (7) Inspect the thermal oxidizer shell for proper sealing, 
corrosion, and hot spots.
    (8) For the burn cycle that follows the inspection, document that 
the thermal oxidizer is operating properly and make any necessary 
adjustments.
    (9) Generally observe whether the equipment is maintained in good 
operating condition.
    (10) Complete all necessary repairs as soon as practicable.
    (c) You must establish procedures for responding to operating 
parameter deviations. At a minimum, the procedures must include the 
information in paragraphs (c)(1) through (3) of this section.
    (1) Procedures for determining the cause of the operating parameter 
deviation.
    (2) Actions for correcting the deviation and returning the operating 
parameters to the allowable ranges or limits.
    (3) Procedures for recording the date and time that the deviation 
began and ended, and the times corrective actions were initiated and 
completed.
    (d) Your plan must specify the recordkeeping procedures to document 
compliance with the emissions and operating limits. Table 1 of this 
subpart establishes the minimum recordkeeping requirements.



Sec. 63.2988  [Reserved]



Sec. 63.2989  How do I change my OMM plan?

    Changes to the operating limits or ranges in your OMM plan require a 
new performance test.
    (a) In order to revise the ranges or levels established for your 
operating limits in Sec. 63.2984, you must meet the requirements in 
paragraphs (a)(1) and (2) of this section:
    (1) Submit a notification of performance test to the Administrator 
as specified in Sec. 63.7(b) to revise your operating ranges or limits.
    (2) After completing the performance test to demonstrate that 
compliance with the emissions limits can be achieved at the revised 
levels of the operating limits, you must submit the performance test 
results and the revised operating limits as part of the notification of 
compliance status required under Sec. 63.9(h).
    (b) If you are revising the inspection and maintenance procedures in 
your plan that are specified in Sec. 63.2987(b), you do not need to 
conduct a new performance test.
    (c) If you plan to operate your process or control device under 
alternative operating conditions and do not wish to revise your OMM plan 
when you change operating conditions, you can perform a separate 
compliance test to establish operating limits for each condition. You 
can then include the operating limits for each condition in your OMM 
plan. After completing the performance tests, you must record the date 
and time when you change operations from one condition to another, the 
condition under which you are operating, and the operating limits that 
apply under that condition. If you can perform a single performance test 
that establishes the most stringent operating limits that cover all 
alternative operating conditions, then you do not need to comply with

Appendix A to Subpart HHHH--Method for Determining Free-Formaldehyde in 
       Urea-Formaldehyde Resins by Sodium Sulfite (Iced & Cooled)

                                1.0 Scope

    This procedure corresponds to the Housing and Urban Development 
method of determining free-formaldehyde in urea-formaldehyde resins. 
This method applies to samples that decompose to yield formaldehyde 
under the conditions of other free-formaldehyde methods. The primary use 
is for urea-formaldehyde resins.

                       2.0 Part A--Testing Resins

    Formaldehyde will react with sodium sulfite to form the sulfite 
addition products and liberate sodium hydroxide (NaOH); however, at room 
temperature, the methanol groups present will also react to liberate 
NaOH. Titrate at 0 degrees Celsius ( [deg]C) to minimize the reaction of 
the methanol groups.
    2.1 Apparatus Required.
    2.1.1 Ice crusher.
    2.1.2 One 100-milliliter (mL) graduated cylinder.
    2.1.3 Three 400-mL beakers.
    2.1.4 One 50-mL burette.
    2.1.5 Analytical balance accurate to 0.1 milligrams (mg).
    2.1.6 Magnetic stirrer.
    2.1.7 Magnetic stirring bars.
    2.1.8 Disposable pipettes.
    2.1.9 Several 5-ounce (oz.) plastic cups.
    2.1.10 Ice cube trays (small cubes).
    2.2 Materials Required.
    2.2.1 Ice cubes (made with distilled water).
    2.2.2 A solution of 1 molar (M) sodium sulfite 
(Na2SO3) (63 grams (g) 
Na2SO3/500 mL water (H2O) neutralized 
to thymolphthalein endpoint).
    2.2.3 Standardized 0.1 normal (N) hydrochloric acid (HCl).
    2.2.4 Thymolphthalein indicator (1.0 g thymolphthalein/199 g 
methanol).
    2.2.5 Sodium chloride (NaCl) (reagent grade).

[[Page 242]]

    2.2.6 Sodium hydroxide (NaOH).
    2.3 Procedure.
    2.3.1 Prepare sufficient quantity of crushed ice for three 
determinations (two trays of cubes).
    2.3.2 Put 70 cubic centimeters (cc) of 1 M 
Na2SO3 solution into a 400-mL beaker. Begin 
stirring and add approximately 100 g of crushed ice and 2 g of NaCl. 
Maintain 0 [deg]C during test, adding ice as necessary.
    2.3.3 Add 10-15 drops of thymolphthalein indicator to the chilled 
solution. If the solution remains clear, add 0.1 N NaOH until the 
solution turns blue; then add 0.1 N HCl back to the colorless endpoint. 
If the solution turns blue upon adding the indicator, add 0.1 N HCl to 
the colorless endpoint.
    2.3.4 On the analytical balance, accurately weigh the amount of 
resin indicated under the ``Resin Sample Size'' chart (see below) as 
follows.

    2.3.4.2 Determine the gross weight of the cup, resin, and disposable 
pipette (with the narrow tip broken off) fitted with a small rubber 
bulb.
    2.3.4.3 Pipette out the desired amount of resin into the stirring, 
chilled solution (approximately 1.5 to 2 g per pipette-full).
    2.3.4.4 Quickly reweigh the cup, resin, and pipette with the bulb.
    2.3.4.5 The resultant weight loss equals the grams of resin being 
tested.
    2.3.5 Rapidly titrate the solution with 0.1 N HCl to the colorless 
endpoint described in Step 3 (2.3.3).
    2.3.6 Repeat the test in triplicate.
    2.4 Calculation.
    2.4.1 The percent free-formaldehyde (%HCHO) is calculated as 
follows:
[GRAPHIC] [TIFF OMITTED] TR11AP02.024

    2.4.2 Compute the average percent free-formaldehyde of the three 
tests.
    (Note: If the results of the three tests are not within a range of 
[plusmn]0.5 percent or if the average of the three tests does not meet 
expected limits, carry out Part B and then repeat Part A.)

                       3.0 Part B--Standard Check

    Part B ensures that test reagents used in determining percent free-
formaldehyde in urea-formaldehyde resins are of proper concentration and 
that operator technique is correct. Should any doubts arise in either of 
these areas, the formaldehyde standard solution test should be carried 
out.
    3.1 Preparation and Standardization of a 1 Percent Formalin 
Solution.
    Prepare a solution containing approximately 1 percent formaldehyde 
from a stock 37 percent formalin solution. Standardize the prepared 
solution by titrating the hydroxyl ions resulting from the formation of 
the formaldehyde bisulfite complex.
    3.2 Apparatus Required.
    Note: All reagents must be American Chemical Society analytical 
reagent grade or better.
    3.2.1 One 1-liter (L) volumetric flask (class A).

    3.3.1 A solution of 37 percent formalin.
    3.3.2 Anhydrous Na2SO3.
    3.3.3 Distilled water.
    3.3.4 Standardized 0.100 N HCl.
    3.3.5 Thymolphthalein indicator (1.0 g thymolphthalein/199 g 
methanol).
    3.4 Preparation of Solutions and Reagents.
    3.4.1 Formaldehyde Standard Solution (approximately 1 percent). 
Measure, using a graduated cylinder, 27.0 mL of analytical reagent 37 
percent formalin solution into a 1-L volumetric flask. Fill the flask to 
volume with distilled water.

[[Page 243]]

    (Note: You must standardize this solution as described in section 
3.5. This solution is stable for 3 months.)
    3.4.2 Sodium Sulfite Solution 1.0 M (used for standardization of 
Formaldehyde Standard Solution). Quantitatively transfer, using 
distilled water as the transfer solvent, 31.50 g of anhydrous 
Na2SO3 into a 250-mL volumetric flask. Dissolve in 
approximately 100 mL of distilled water and fill to volume.
    (Note: You must prepare this solution daily, but the calibration of 
the Formaldehyde Standard Solution needs to be done only once.)
    3.4.3 Hydrochloric Acid Standard Solution 0.100 M. This reagent 
should be readily available as a primary standard that only needs to be 
diluted.
    3.5 Standardization.
    3.5.1 Standardization of Formaldehyde Standard Solution.
    3.5.1.1 Pipette 100.0 mL of 1 M sodium sulfite into a stirred 250-mL 
beaker.
    3.5.1.2 Using a standardized pH meter, measure and record the pH. 
The pH should be around 10. It is not essential the pH be 10; however, 
it is essential that the value be accurately recorded.
    3.5.1.3 To the stirring Na2SO3 solution, 
pipette in 10.0 mL of Formaldehyde Standard Solution. The pH should rise 
sharply to about 12.
    3.5.1.4 Using the pH meter as a continuous monitor, titrate the 
solution back to the original exact pH using 0.100 N HCl. Record the 
milliliters of HCl used as titrant. (Note: Approximately 30 to 35 mL of 
HCl will be required.)
    3.5.1.5 Calculate the concentration of the Formaldehyde Standard 
Solution using the equation as follows:

and 2 g NaCl. Maintain 0 [deg]C during the test, adding ice as 
necessary.
    3.6.3 Add 10-15 drops of thymolphthalein indicator to the chilled 
solution. If the solution remains clear, add 0.1 N NaOH until the 
solution turns blue; then add 0.1 N HCl back to the colorless endpoint. 
If the solution turns blue upon adding the indicator, add 0.1 N HCl to 
the colorless endpoint.
    3.6.4 On the analytical balance, accurately weigh a sample of 
Formaldehyde Standard Solution as follows.
    3.6.4.1 Pour about 0.5 inches of Formaldehyde Standard Solution into 
a 5-oz. plastic cup.

    The purpose of this test is to determine the loss-on-ignition (LOI) 
of wet-formed fiberglass mat.

                              2.0 Equipment

    2.1 Scale sensitive to 0.001 gram (g).

[[Page 244]]

    2.2 Drying oven equipped with a means of constant temperature 
regulation and mechanical air convection.
    2.3 Furnace designed to heat to at least 625 [deg]C (1,157 [deg]F) 
and controllable to [plusmn]25 [deg]C ([plusmn]45 [deg]F).
    2.4 Crucible, high form, 250 milliliter (mL).
    2.5 Desiccator.
    2.6 Pan balance (see Note 2 in 4.9)

                     3.0 Sample Collection Procedure

    3.1 Obtain a sample of mat in accordance with Technical Association 
of the Pulp and Paper Industry (TAPPI) method 1007 ``Sample Location.''
    3.2 Use a 5- to 10-g sample cut into pieces small enough to fit into 
the crucible.
    3.3 Place the sample in the crucible. (Note 1: To test without the 
use of a crucible, see Note 2 after Section 4.8.)
    3.4 Condition the sample in the furnace set at 105 [plusmn] 3 [deg]C 
(221 [plusmn] 9 [deg]F) for 5 minutes [plusmn] 30 seconds.

                              4.0 Procedure

    4.1 Condition each sample by drying for 5 minutes [plusmn] 30 
seconds at 105 [plusmn] 3 [deg]C (22 [plusmn] 5 [deg]F).
    4.2 Remove the test sample from the furnace and cool in the 
desiccator for 30 minutes in the standard atmosphere for testing glass 
textiles.
    4.3 Place the empty crucible in the furnace at 625 [plusmn] 25 
[deg]C (1,157 [plusmn] 45 [deg]F). After 30 minutes, remove and cool the 
crucible in the standard atmosphere (TAPPI method 1008) for 30 minutes.
    4.4 Identify each crucible with respect to each test sample of mat.
    4.5 Weigh the empty crucible to the nearest 0.001 g. Record this 
weight as the tare mass, T.
    4.6 Place the test sample in the crucible and weigh to the nearest 
0.001 g. Record this weight as the initial mass, A.
    4.7 Place the test sample and crucible in the furnace and ignite at 
625 [plusmn] 25 [deg]C (1,157 [plusmn] 45 [deg]F).
    4.8 After ignition for at least 30 minutes, remove the test sample 
and crucible from the furnace and cool in the desiccator for 30 minutes 
in the standard atmosphere (TAPPI method 1008).
    4.9 Remove each crucible, and test each sample separately from the 
desiccator, and immediately weigh each sample to the nearest 0.001 g. 
Record this weight as the ignited mass, B. (Note 2: When it is known 
that no ash residue separates from the test sample during the weighing 
and igniting processes, you may weigh the sample separately without the 
crucible. When this occurs, the tare mass (T) equals zero. With 
appropriate care, you can dry and weigh a single piece of mat and place 
with tongs into the ignition oven on appropriate refractory supports. 
When the ignition time is over, remove the sample as an intact fragile 
web and weigh it directly on a pan balance.)

                             5.0 Calculation

    5.1 Calculate the LOI for each sample as follows:
    [GRAPHIC] [TIFF OMITTED] TR11AP02.027
    
Where:

A = initial mass of crucible and sample before ignition (g);
B = mass of crucible and glass residue after ignition (g); and
T = tare mass of crucible, (g) (see Note 2).

    5.2 Report the percent LOI of the glass mat to the nearest 0.1 
percent.

                              6.0 Precision

    The repeatability of this test method for measurements on adjacent 
specimens from the same sample of mat is better than 1 percent.

                        What This Subpart Covers



63.3280  What is in this subpart?

    This subpart describes the actions you must take to reduce emissions 
of organic hazardous air pollutants (HAP) from paper and other web 
coating operations. This subpart establishes emission standards for web 
coating lines and specifies what you must do to comply if you own or 
operate a facility with web coating lines that is a major source of HAP. 
Certain requirements apply to all who are subject to this subpart; 
others depend on the means you use to comply with an emission standard.



Sec. 63.3290  Does this subpart apply to me?

    The provisions of this subpart apply to each new and existing 
facility that is a major source of HAP, as defined in Sec. 63.2, at 
which web coating lines are operated.

[[Page 245]]



Sec. 63.3300  Which of my emission sources are affected by this subpart?

    The affected source subject to this subpart is the collection of all 
web coating lines at your facility. This includes web coating lines 
engaged in the coating of metal webs that are used in flexible 
packaging, and web coating lines engaged in the coating of fabric 
substrates for use in pressure sensitive tape and abrasive materials. 
Web coating lines specified in paragraphs (a) through (g) of this 
section are not part of the affected source of this subpart.
    (a) Any web coating line that is stand-alone coating equipment under 
subpart KK of this part (national emission standards for the printing 
and publishing industry) which the owner or operator includes in the 
affected source under subpart KK.

General Requirements for Compliance With the Emission Standards and for 
                    Monitoring and Performance Tests



Sec. 63.3340  What general requirements must I meet to comply with the standards?

    Table 2 to this subpart specifies the provisions of subpart A of 
this part that apply if you are subject to this subpart, such as 
startup, shutdown, and malfunction plans (SSMP) in Sec. 63.6(e)(3) for 
affected sources using a control device to comply with the emission 
standards.



Sec. 63.3350  If I use a control device to comply with the emission standards, what monitoring must I do?

    (a) A summary of monitoring you must do follows:

------------------------------------------------------------------------
 If you operate a web coating
line, and have the following:                Then you must:
------------------------------------------------------------------------
(1) Intermittently-controlled  Record parameters related to possible
 work stations.                 exhaust flow bypass of control device
                                and to coating use (Sec.  63.3350(c)).
(2) Solvent recovery unit....  Operate continuous emission monitoring
                                system and perform quarterly audits or
                                determine volatile matter recovered and
                                conduct a liquid-liquid material balance
                                (Sec.  63.3350(d)).
(3) Control Device...........  Operate continuous parameter monitoring
                                system (Sec.  63.3350(e)).
(4) Capture system...........  Monitor capture system operating
                                parameter (Sec.  63.3350(f)).
------------------------------------------------------------------------

    (b) Following the date on which the initial performance test of a 
control device is completed to demonstrate continuing compliance with 
the standards, you must monitor and inspect each capture system and each 
control device used to comply with Sec. 63.3320. You must install and 
operate the monitoring equipment as specified in paragraphs (c) and (f) 
of this section.
    (c) Bypass and coating use monitoring. If you own or operate web 
coating lines with intermittently-controlled work stations, you must 
monitor bypasses of the control device and the mass of each coating 
material applied at the work station during any such bypass. If using a 
control device for complying with the requirements of this subpart, you 
must demonstrate that any coating material applied on a never-controlled 
work station or an intermittently-controlled work station operated in 
bypass mode is allowed in your compliance demonstration according to 
Sec. 63.3370(n) and (o). The bypass monitoring must be conducted using 
at least one of the procedures in paragraphs (c)(1) through (4) of this 
section for each work station and associated dryer.
    (1) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that provides a record indicating whether the 
exhaust stream from the dryer was directed to the control device or was 
diverted from the control device. The time and flow control position 
must be recorded at least once per hour as well as every time the flow 
direction is changed. A flow control position indicator must be 
installed at the entrance to any bypass line that could

[[Page 249]]

divert the exhaust stream away from the control device to the 
atmosphere.
    (2) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. A visual inspection of the seal or closure mechanism must 
be performed at least once every month to ensure that the valve or 
damper is maintained in the closed position, and the exhaust stream is 
not diverted through the bypass line.
    (3) Valve closure continuous monitoring. Ensure that any bypass line 
valve or damper is in the closed position through continuous monitoring 
of valve position when the emission source is in operation and is using 
a control device for compliance with the requirements of this subpart. 
The monitoring system must be inspected at least once every month to 
verify that the monitor will indicate valve position.
    (4) Automatic shutdown system. Use an automatic shutdown system in 
which the web coating line is stopped when flow is diverted away from 
the control device to any bypass line when the control device is in 
operation. The automatic system must be inspected at least once every 
month to verify that it will detect diversions of flow and would shut 
down operations in the event of such a diversion.
    (d) Solvent recovery unit. If you own or operate a solvent recovery 
unit to comply with Sec. 63.3320, you must meet the requirements in 
either paragraph (d)(1) or (2) of this section depending on how control 
efficiency is determined.
    (1) Continuous emission monitoring system (CEMS). If you are 
demonstrating compliance with the emission standards in Sec. 63.3320 
through continuous emission monitoring of a control device, you must 
install, calibrate, operate, and maintain the CEMS according to 
paragraphs (d)(1)(i) through (iii) of this section.
    (i) Measure the total organic volatile matter mass flow rate at both 
the control device inlet and the outlet such that the reduction 
efficiency can be determined. Each continuous emission monitor must 
comply with performance specification 6, 8, or 9 of 40 CFR part 60, 
appendix B, as appropriate.
    (ii) You must follow the quality assurance procedures in procedure 
1, appendix F of 40 CFR part 60. In conducting the quarterly audits of 
the monitors as required by procedure 1, appendix F, you must use 
compounds representative of the gaseous emission stream being 
controlled.
    (iii) You must have valid data from at least 90 percent of the hours 
during which the process is operated.
    (2) Liquid-liquid material balance. If you are demonstrating 
compliance with the emission standards in Sec. 63.3320 through liquid-
liquid material balance, you must install, calibrate, maintain, and 
operate according to the manufacturer's specifications a device that 
indicates the cumulative amount of volatile matter recovered by the 
solvent recovery device on a monthly basis. The device must be certified 
by the manufacturer to be accurate to within [plusmn]2.0 percent by 
mass.
    (e) Continuous parameter monitoring system (CPMS). If you are using 
a control device to comply with the emission standards in Sec. 63.3320, 
you must install, operate, and maintain each CPMS specified in 
paragraphs (e)(9) and (10) and (f) of this section according to the 
requirements in paragraphs (e)(1) through (8) of this section. You must 
install, operate, and maintain each CPMS specified in paragraph (c) of 
this section according to paragraphs (e)(5) through (7) of this section.
    (1) Each CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation to have a valid hour 
of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the hourly average of all recorded readings 
according to paragraphs (e)(3)(i) and (ii) of this section.
    (i) To calculate a valid hourly value, you must have at least three 
of four equally spaced data values from that hour from a continuous 
monitoring system (CMS) that is not out-of-control.
    (ii) Provided all of the readings recorded in accordance with 
paragraph

[[Page 250]]

(e)(3) of this section clearly demonstrate continuous compliance with 
the standard that applies to you, then you are not required to determine 
the hourly average of all recorded readings.
    (4) You must determine the rolling 3-hour average of all recorded 
readings for each operating period. To calculate the average for each 3-
hour averaging period, you must have at least two of three of the hourly 
averages for that period using only average values that are based on 
valid data (i.e., not from out-of-control periods).
    (5) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (6) At all times, you must maintain the monitoring system in proper 
working order including, but not limited to, maintaining necessary parts 
for routine repairs of the monitoring equipment.
    (7) Except for monitoring malfunctions, associated repairs, or 
required quality assurance or control activities (including calibration 
checks or required zero and span adjustments), you must conduct all 
monitoring at all times that the unit is operating. Data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities shall not be used for 
purposes of calculating the emissions concentrations and percent 
reductions specified in Sec. 63.3370. You must use all the valid data 
collected during all other periods in assessing compliance of the 
control device and associated control system. A monitoring malfunction 
is any sudden, infrequent, not reasonably preventable failure of the 
monitoring system to provide valid data. Monitoring failures that are 
caused in part by poor maintenance or careless operation are not 
malfunctions.
    (8) Any averaging period for which you do not have valid monitoring 
data and such data are required constitutes a deviation, and you must 
notify the Administrator in accordance with Sec. 63.3400(c).
    (9) Oxidizer. If you are using an oxidizer to comply with the 
emission standards, you must comply with paragraphs (e)(9)(i) through 
(iii) of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to the manufacturer's specifications. The 
calibration of the chart recorder, data logger, or temperature indicator 
must be verified every 3 months or the chart recorder, data logger, or 
temperature indicator must be replaced. You must replace the equipment 
whether you choose not to perform the calibration or the equipment 
cannot be calibrated properly.
    (ii) For an oxidizer other than a catalytic oxidizer, install, 
calibrate, operate, and maintain a temperature monitoring device 
equipped with a continuous recorder. The device must have an accuracy of 
[plusmn]1 percent of the temperature being monitored in degrees Celsius, 
or [plusmn]1 [deg]Celsius, whichever is greater. The thermocouple or 
temperature sensor must be installed in the combustion chamber at a 
location in the combustion zone.
    (iii) For a catalytic oxidizer, install, calibrate, operate, and 
maintain a temperature monitoring device equipped with a continuous 
recorder. The device must be capable of monitoring temperature with an 
accuracy of [plusmn]1 percent of the temperature being monitored in 
degrees Celsius or [plusmn] 1 degree Celsius, whichever is greater. The 
thermocouple or temperature sensor must be installed in the vent stream 
at the nearest feasible point to the inlet and outlet of the catalyst 
bed. Calculate the temperature rise across the catalyst.
    (10) Other types of control devices. If you use a control device 
other than an oxidizer or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of an alternative monitoring method under 
Sec. 63.8(f).
    (f) Capture system monitoring. If you are complying with the 
emission standards in Sec. 63.3320 through the use of a capture system 
and control device for one or more web coating lines, you must develop a 
site-specific monitoring plan containing the information specified in 
paragraphs (f)(1) and (2) of this section for these capture systems. You 
must monitor the capture system in accordance with paragraph (f)(3) of 
this

[[Page 251]]

section. You must make the monitoring plan available for inspection by 
the permitting authority upon request.
    (1) The monitoring plan must:
    (i) Identify the operating parameter to be monitored to ensure that 
the capture efficiency determined during the initial compliance test is 
maintained; and
    (ii) Explain why this parameter is appropriate for demonstrating 
ongoing compliance; and
    (iii) Identify the specific monitoring procedures.
    (2) The monitoring plan must specify the operating parameter value 
or range of values that demonstrate compliance with the emission 
standards in Sec. 63.3320. The specified operating parameter value or 
range of values must represent the conditions present when the capture 
system is being properly operated and maintained.
    (3) You must conduct all capture system monitoring in accordance 
with the plan.
    (4) Any deviation from the operating parameter value or range of 
values which are monitored according to the plan will be considered a 
deviation from the operating limit.
    (5) You must review and update the capture system monitoring plan at 
least annually.



Sec. 63.3360  What performance tests must I conduct?

    (a) The performance test methods you must conduct are as follows:

------------------------------------------------------------------------
 If you control organic HAP on any
individual web coating line or any                You must:
  group of web coating lines by:
------------------------------------------------------------------------
(1) Limiting organic HAP or          Determine the organic HAP or
 volatile matter content of          volatile matter and coating solids
 coatings.                           content of coating materials
                                     according to procedures in Sec.
                                     63.3360(c) and (d). If applicable,
                                     determine the mass of volatile
                                     matter retained in the coated web
                                     or otherwise not emitted to the
                                     atmosphere according to Sec.
                                     63.3360(g).
(2) Using a capture and control      Conduct a performance test for each
 system.                             capture and control system to
                                     determine: the destruction or
                                     removal efficiency of each control
                                     device other than solvent recovery
                                     according to Sec.  63.3360(e), and
                                     the capture efficiency of each
                                     capture system according to Sec.
                                     63.3360(f). If applicable,
                                     determine the mass of volatile
                                     matter retained in the coated web
                                     or otherwise not emitted to the
                                     atmosphere according to Sec.
                                     63.3360(g).
------------------------------------------------------------------------

    (b) If you are using a control device to comply with the emission 
standards in Sec. 63.3320, you are not required to conduct a performance 
test to demonstrate compliance if one or more of the criteria in 
paragraphs (b)(1) through (3) of this section are met.
    (1) The control device is equipped with continuous emission monitors 
for determining inlet and outlet total organic volatile matter 
concentration and capture efficiency has been determined in accordance 
with the requirements of this subpart such that an overall organic HAP 
control efficiency can be calculated, and the continuous emission 
monitors are used to demonstrate continuous compliance in accordance 
with Sec. 63.3350; or
    (2) You have met the requirements of Sec. 63.7(h) (for waiver of 
performance testing; or
    (3) The control device is a solvent recovery system and you comply 
by means of a monthly liquid-liquid material balance.
    (c) Organic HAP content. If you determine compliance with the 
emission standards in Sec. 63.3320 by means other than determining the 
overall organic HAP control efficiency of a control device, you must 
determine the organic HAP mass fraction of each coating material ``as-
purchased'' by following one of the procedures in paragraphs (c)(1) 
through (3) of this section, and determine the organic HAP mass fraction 
of each coating material ``as-applied'' by following the procedures in 
paragraph (c)(4) of this section. If the organic HAP content values are 
not determined using the procedures in paragraphs (c)(1) through (3) of 
this section, the owner or operator must submit an alternative test 
method for determining their values for approval by the Administrator in 
accordance with Sec. 63.7(f). The recovery efficiency of the test method 
must be determined for all of

[[Page 252]]

the target organic HAP and a correction factor, if necessary, must be 
determined and applied.
    (1) Method 311. You may test the coating material in accordance with 
Method 311 of appendix A of this part. The Method 311 determination may 
be performed by the manufacturer of the coating material and the results 
provided to the owner or operator. The organic HAP content must be 
calculated according to the criteria and procedures in paragraphs 
(c)(1)(i) through (iii) of this section.
    (i) Include each organic HAP determined to be present at greater 
than or equal to 0.1 mass percent for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and greater than or equal to 1.0 mass percent for other 
organic HAP compounds.
    (ii) Express the mass fraction of each organic HAP you include 
according to paragraph (c)(1)(i) of this section as a value truncated to 
four places after the decimal point (for example, 0.3791).
    (iii) Calculate the total mass fraction of organic HAP in the tested 
material by summing the counted individual organic HAP mass fractions 
and truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24. For coatings, determine the volatile organic content 
as mass fraction of nonaqueous volatile matter and use it as a 
substitute for organic HAP using Method 24 of 40 CFR part 60, appendix 
A. The Method 24 determination may be performed by the manufacturer of 
the coating and the results provided to you.
    (3) Formulation data. You may use formulation data to determine the 
organic HAP mass fraction of a coating material. Formulation data may be 
provided to the owner or operator by the manufacturer of the material. 
In the event of an inconsistency between Method 311 (appendix A of 40 
CFR part 63) test data and a facility's formulation data, and the Method 
311 test value is higher, the Method 311 data will govern. Formulation 
data may be used provided that the information represents all organic 
HAP present at a level equal to or greater than 0.1 percent for OSHA-
defined carcinogens as specified in 29 CFR 1910.1200(d)(4) and equal to 
or greater than 1.0 percent for other organic HAP compounds in any raw 
material used.
    (4) As-applied organic HAP mass fraction. If the as-purchased 
coating material is applied to the web without any solvent or other 
material added, then the as-applied organic HAP mass fraction is equal 
to the as-purchased organic HAP mass fraction. Otherwise, the as-applied 
organic HAP mass fraction must be calculated using Equation 1a of 
Sec. 63.3370.
    (d) Volatile organic and coating solids content. If you determine 
compliance with the emission standards in Sec. 63.3320 by means other 
than determining the overall organic HAP control efficiency of a control 
device and you choose to use the volatile organic content as a surrogate 
for the organic HAP content of coatings, you must determine the as-
purchased volatile organic content and coating solids content of each 
coating material applied by following the procedures in paragraph (d)(1) 
or (2) of this section, and the as-applied volatile organic content and 
coating solids content of each coating material by following the 
procedures in paragraph (d)(3) of this section.
    (1) Method 24. You may determine the volatile organic and coating 
solids mass fraction of each coating applied using Method 24 (40 CFR 
part 60, appendix A.) The Method 24 determination may be performed by 
the manufacturer of the material and the results provided to you. If 
these values cannot be determined using Method 24, you must submit an 
alternative technique for determining their values for approval by the 
Administrator.
    (2) Formulation data. You may determine the volatile organic content 
and coating solids content of a coating material based on formulation 
data and may rely on volatile organic content data provided by the 
manufacturer of the material. In the event of any inconsistency between 
the formulation data and the results of Method 24 of 40 CFR part 60, 
appendix A, and the Method 24 results are higher, the results of Method 
24 will govern.
    (3) As-applied volatile organic content and coating solids content. 
If the as-purchased coating material is applied to the web without any 
solvent or other

[[Page 253]]

material added, then the as-applied volatile organic content is equal to 
the as-purchased volatile content and the as-applied coating solids 
content is equal to the as-purchased coating solids content. Otherwise, 
the as-applied volatile organic content must be calculated using 
Equation 1b of Sec. 63.3370 and the as-applied coating solids content 
must be calculated using Equation 2 of Sec. 63.3370.
    (e) Control device efficiency. If you are using an add-on control 
device other than solvent recovery, such as an oxidizer, to comply with 
the emission standards in Sec. 63.3320, you must conduct a performance 
test to establish the destruction or removal efficiency of the control 
device according to the methods and procedures in paragraphs (e)(1) and 
(2) of this section. During the performance test, you must establish the 
operating limits required by Sec. 63.3321 according to paragraph (e)(3) 
of this section.
    (1) An initial performance test to establish the destruction or 
removal efficiency of the control device must be conducted such that 
control device inlet and outlet testing is conducted simultaneously, and 
the data are reduced in accordance with the test methods and procedures 
in paragraphs (e)(1)(i) through (ix) of this section. You must conduct 
three test runs as specified in Sec. 63.7(e)(3), and each test run must 
last at least 1 hour.
    (i) Method 1 or 1A of 40 CFR part 60, appendix A, must be used for 
sample and velocity traverses to determine sampling locations.
    (ii) Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A, 
must be used to determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of 40 CFR part 60, appendix A, must be 
used for gas analysis to determine dry molecular weight. You may also 
use as an alternative to Method 3B the manual method for measuring the 
oxygen, carbon dioxide, and carbon monoxide content of exhaust gas in 
ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus],'' (incorporated by reference, see 
Sec. 63.14).
    (iv) Method 4 of 40 CFR part 60, appendix A, must be used to 
determine stack gas moisture.
    (v) The gas volumetric flow rate, dry molecular weight, and stack 
gas moisture must be determined during each test run specified in 
paragraph (f)(1)(vii) of this section.
    (vi) Method 25 or 25A of 40 CFR part 60, appendix A, must be used to 
determine total gaseous non-methane organic matter concentration. Use 
the same test method for both the inlet and outlet measurements which 
must be conducted simultaneously. You must submit notice of the intended 
test method to the Administrator for approval along with notification of 
the performance test required under Sec. 63.7(b). You must use Method 
25A if any of the conditions described in paragraphs (e)(1)(vi)(A) 
through (D) of this section apply to the control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer but an exhaust gas volatile 
organic matter concentration of 50 ppmv or less is required to comply 
with the emission standards in Sec. 63.3320; or
    (C) The control device is an oxidizer but the volatile organic 
matter concentration at the inlet to the control system and the required 
level of control are such that they result in exhaust gas volatile 
organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer but because of the high 
efficiency of the control device the anticipated volatile organic matter 
concentration at the control device exhaust is 50 ppmv or less, 
regardless of inlet concentration.
    (vii) Except as provided in Sec. 63.7(e)(3), each performance test 
must consist of three separate runs with each run conducted for at least 
1 hour under the conditions that exist when the affected source is 
operating under normal operating conditions. For the purpose of 
determining volatile organic compound concentrations and mass flow 
rates, the average of the results of all the runs will apply.
    (viii) Volatile organic matter mass flow rates must be determined 
for each run specified in paragraph (e)(1)(vii) of

[[Page 254]]

this section using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR04DE02.025

Where:

Mf = Total organic volatile matter mass flow rate, kilograms 
(kg)/hour (h).
Qsd = Volumetric flow rate of gases entering or exiting the 
control device, as determined according to Sec. 63.3360(e)(1)(ii), dry 
standard cubic meters (dscm)/h.
Cc = Concentration of organic compounds as carbon, ppmv.
12.0 = Molecular weight of carbon.
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
(mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury (mmHg)).

    (ix) For each run, emission control device destruction or removal 
efficiency must be determined using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR04DE02.026

Where:

E = Organic volatile matter control efficiency of the control device, 
percent.
Mfi = Organic volatile matter mass flow rate at the inlet to 
the control device, kg/h.
Mfo = Organic volatile matter mass flow rate at the outlet of 
the control device, kg/h.

    (x) The control device destruction or removal efficiency is 
determined as the average of the efficiencies determined in the test 
runs and calculated in Equation 2 of this section.
    (2) You must record such process information as may be necessary to 
determine the conditions in existence at the time of the performance 
test. Operations during periods of startup, shutdown, and malfunction 
will not constitute representative conditions for the purpose of a 
performance test.
    (3) Operating limits. If you are using one or more add-on control 
device other than a solvent recovery system for which you conduct a 
liquid-liquid material balance to comply with the emission standards in 
Sec. 63.3320, you must establish the applicable operating limits 
required by Sec. 63.3321. These operating limits apply to each add-on 
emission control device, and you must establish the operating limits 
during the performance test required by paragraph (e) of this section 
according to the requirements in paragraphs (e)(3)(i) and (ii) of this 
section.
    (i) Thermal oxidizer. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs 
(e)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (ii) Catalytic oxidizer. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to 
paragraphs (e)(3)(ii)(A) and (B) or paragraphs (e)(3)(ii)(C) and (D) of 
this section.
    (A) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (B) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (C) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(e)(3)(ii)(D) of this section.

[[Page 255]]

During the performance test, you must monitor and record the temperature 
just before the catalyst bed at least once every 15 minutes during each 
of the three test runs. Use the data collected during the performance 
test to calculate and record the average temperature just before the 
catalyst bed during the performance test. This is the minimum operating 
limit for your catalytic oxidizer.
    (D) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (e)(3)(ii)(C) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs 
(e)(3)(ii)(D)(1) through (3) of this section.
    (1) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures,
    (2) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems, and
    (3) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency in accordance with this section.
    (f) Capture efficiency. If you demonstrate compliance by meeting the 
requirements of Sec. 63.3370(e), (f), (g), (h), (i)(2), (k), (n)(2) or 
(3), or (p), you must determine capture efficiency using the procedures 
in paragraph (f)(1), (2), or (3) of this section, as applicable.
    (1) You may assume your capture efficiency equals 100 percent if 
your capture system is a permanent total enclosure (PTE). You must 
confirm that your capture system is a PTE by demonstrating that it meets 
the requirements of section 6 of EPA Method 204 of 40 CFR part 51, 
appendix M, and that all exhaust gases from the enclosure are delivered 
to a control device.
    (2) You may determine capture efficiency according to the protocols 
for testing with temporary total enclosures that are specified in 
Methods 204 and 204A through F of 40 CFR part 51, appendix M. You may 
exclude never-controlled work stations from such capture efficiency 
determinations.
    (3) You may use any capture efficiency protocol and test methods 
that satisfy the criteria of either the Data Quality Objective or the 
Lower Confidence Limit approach as described in appendix A of subpart KK 
of this part. You may exclude never-controlled work stations from such 
capture efficiency determinations.
    (g) Volatile matter retained in the coated web or otherwise not 
emitted to the atmosphere. You may choose to take into account the mass 
of volatile matter retained in the coated web after curing or drying or 
otherwise not emitted to the atmosphere when determining compliance with 
the emission standards in Sec. 63.3320. If you choose this option, you 
must develop a testing protocol to determine the mass of volatile matter 
retained in the coated web or otherwise not emitted to the atmosphere 
and submit this protocol to the Administrator for approval. You must 
submit this protocol with your site-specific test plan under 
Sec. 63.7(f). If you intend to take into account the mass of volatile 
matter retained in the coated web after curing or drying or otherwise 
not emitted to the atmosphere and demonstrate compliance according to 
Sec. 63.3370(c)(3), (c)(4), (c)(5), or (d), then the test protocol you 
submit must determine the mass of organic HAP retained in the coated web 
or otherwise not emitted to the atmosphere. Otherwise, compliance must 
be shown using the volatile organic matter content as a surrogate for 
the HAP content of the coatings.
    (h) Control devices in series. If you use multiple control devices 
in series to comply with the emission standards in Sec. 63.3320, the 
performance test must include, at a minimum, the inlet to the first 
control device in the series, the outlet of the last control device in 
the series, and all intermediate streams (e.g., gaseous exhaust to the 
atmosphere or a liquid stream from a recovery device) that are not 
subsequently treated by any of the control devices in the series.

[[Page 262]]

basis is achieved as long as the capture efficiency is 100 percent as 
detailed in Sec. 63.3320(b)(4). Unless one of the cases described in 
paragraph (e)(1), (2), or (3) of this section applies to the affected 
source, you must either demonstrate compliance in accordance with the 
procedure in paragraph (i) of this section when emissions from the 
affected source are controlled by a solvent recovery device, or the 
procedure in paragraph (k) of this section when emissions are controlled 
by an oxidizer or demonstrate compliance for a web coating line by

you must demonstrate compliance in accordance with the provisions of 
paragraph (n) of this section.
    (3) An alternative method of demonstrating compliance with 
Sec. 63.3320(b)(1) is the installation of a PTE around the web coating 
line that achieves 100 percent capture efficiency and ventilation of all 
organic HAP emissions from the total enclosure to an oxidizer with an 
outlet organic HAP concentration of no greater than 20 ppmv by compound 
on a dry basis. If this method is selected, you must demonstrate 
compliance by following the procedures in paragraphs (e)(3)(i) and (ii) 
of this section. Compliance is determined according to paragraph

source to no more than 0.20 kg organic HAP emitted per kg coating solids 
applied, and from a new affected source to no more than 0.08 kg organic 
HAP emitted per kg coating solids applied as determined on a monthly 
average as-applied basis. If the affected source operates more than one 
capture system, more than one control device, one or more never-
controlled work stations, or one or more intermittently-controlled work 
stations, then you must demonstrate compliance in accordance with the 
provisions of paragraph (n) of this section. Otherwise, you must 
demonstrate compliance following the procedure in paragraph (i) of this 
section when emissions from the affected source are controlled by a 
solvent recovery device or the procedure in paragraph (k) of this 
section when emissions are controlled by an oxidizer.
    (g) Capture and control to achieve mass fraction limit

stations, or one or more intermittently-controlled work stations, then 
you must demonstrate compliance in accordance

[[Page 263]]

with the provisions of paragraph (n) of this section. Otherwise, you 
must demonstrate compliance following the procedure in paragraph (i) of 
this section when emissions from the affected source are controlled by a

a capture system and control device and limit the monthly organic HAP 
emissions to less than the allowable emissions as calculated in 
accordance with paragraph (l) of this section. If the affected source 
operates more than one capture system, more than one control device, one 
or more never-controlled work stations, or one or more intermittently-
controlled work stations, then you must demonstrate compliance in 
accordance with the provisions of paragraph (n) of this section. 
Otherwise, the owner or operator must demonstrate compliance following

at an existing affected source or 0.08 kg organic HAP per kg coating 
solids at a new affected source, and coating material applied at less 
than 20 mass percent coating solids complying with 4 mass percent 
organic HAP at an existing affected source and 1.6 mass-percent organic 
HAP at a new affected source as follows:
    (1) Determine the as-purchased mass of each coating material applied 
each month.
    (2) Determine the as-purchased coating solids content of each 
coating material applied each month in accordance with 
Sec. 63.3360(d)(1).
    (3) Determine the as-purchased mass fraction of each coating 
material which was applied at 20 mass percent or greater coating solids 
content on an as-applied basis.
    (4) Determine the total mass of each solvent, diluent, thinner, or 
reducer added to coating materials which were applied at less than 20 
mass percent coating solids content on an as-applied basis each month.

    (n) Combinations of capture and control. If you operate more than 
one capture system, more than one control device, one or more never-
controlled work stations, or one or more intermittently-controlled work 
stations, you must calculate organic HAP emissions according to the 
procedures in paragraphs (n)(1) through (4) of this section, and use the 
calculation procedures specified in paragraph (n)(5) of this section to 
convert the monitoring and other data into units of the selected control 
option in paragraphs (e) through (h) of this section. Use the procedures 
specified in paragraph (n)(6) of this section to demonstrate compliance.
    (1) Solvent recovery system using liquid-liquid material balance 
compliance demonstration. If you choose to comply by means of a liquid-
liquid material balance for each solvent recovery system used to control 
one or more web coating lines, you must determine the organic HAP 
emissions for those web coating lines controlled by that solvent 
recovery system either:
    (i) In accordance with paragraphs (i)(1)(i) through (iii) and (v)

(o) of this section, if the web coating lines served by that capture and 
control system have one or more never-controlled or intermittently-
controlled work stations.

uncontrolled web coating lines, you must determine the organic HAP 
applied on those web coating lines using Equation 6 of this section. The 
organic HAP emitted from an uncontrolled web coating line is equal to 
the organic HAP applied on that web coating line.

Subpart NNNN--National Emission Standards for Hazardous Air Pollutants: 
                   Surface Coating of Large Appliances

    Source: 67 FR 48262, July 23, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4080  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants for large appliance surface coating facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.4081  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a facility 
that applies coatings to large appliance parts or products, and is a 
major source, is located at a major source, or is part of a major source 
of emissions of hazardous air pollutants (HAP), except as provided in 
paragraph (d) of this section. A major source of HAP emissions is any 
stationary source or group of stationary sources located within a 
contiguous area and under common control that emits or has the potential 
to emit any single HAP at a rate of 9.07 megagrams (Mg) (10 tons) or 
more per year or any combination of HAP at a rate of 22.68 Mg (25 tons) 
or more per year. You are not subject to this subpart if your large 
appliance surface coating facility is located at, or is part of, an area 
source of HAP emissions. An area source of HAP emissions is any 
stationary source or group of stationary sources located within a 
contiguous area and under common control that is not a major source.
    (b) The large appliance surface coating source category includes any 
facility engaged in the surface coating of a

[[Page 278]]

large appliance part or product. Large appliance parts and products 
include but are not limited to cooking equipment; refrigerators, 
freezers, and refrigerated cabinets and cases; laundry equipment; 
dishwashers, trash compactors, and water heaters; and heating, 
ventilation, and air-conditioning (HVAC) units, air-conditioning (except 
motor vehicle) units, air-conditioning and heating combination units, 
comfort furnaces, and electric heat pumps. Specifically excluded are 
heat transfer coils and large commercial and industrial chillers.
    (c) The large appliance surface coating activities and equipment to 
which this subpart applies are listed in paragraphs (c)(1) through (9) 
of this section:
    (1) Surface preparation of large appliance parts and products;
    (2) Preparation of a coating for application (e.g., mixing in 
thinners and other components);
    (3) Application of a coating to large appliance parts and products 
using, for example, spray guns or dip tanks;
    (4) Application of porcelain enamel, powder coating, and asphalt 
interior soundproofing coating;
    (5) Flash-off, drying, or curing following the coating application 
operation;
    (6) Cleaning of equipment used in coating operations (e.g., 
application equipment, hangers, racks);
    (7) Storage of coatings, thinners, and cleaning materials;
    (8) Conveying of coatings, thinners, and cleaning materials from 
storage areas to mixing areas or coating application areas, either 
manually (e.g., in buckets) or by automated means (e.g., transfer 
through pipes using pumps); and
    (9) Handling and conveying of waste materials generated by coating 
operations.
    (d) This subpart does not apply to surface coating that meets any of 
the criteria of paragraphs (d)(1) through (5) of this section.
    (1) The surface coating of large appliance parts such as metal or 
plastic handles, hinges, or fasteners that have a wider use beyond large 
appliances is not subject to this subpart.
    (2) The surface coating of large appliances conducted for the 
purpose of repairing or maintaining large appliances used by a facility 
and not for commerce is not subject to this subpart unless organic HAP 
emissions from the surface coating itself are as high as the rates 
specified in paragraph (a) of this section.
    (3) The surface coating of heat transfer coils or large commercial 
and industrial chillers.
    (4) The provisions of this subpart do not apply to research or 
laboratory facilities; janitorial, building, and facility maintenance 
operations; hobby shops operated for noncommercial purposes or coating 
applications using hand-held non-refillable aerosol containers.
    (5) The provisions of this subpart do not apply to processes 
involving metal plating or phosphating of a substrate.
    (e) If you own or operate an affected source that is subject to this 
subpart and at the same affected source you also perform surface coating 
subject to any other subparts in this part, you may choose for the 
affected source to comply with only one subpart. In order to choose this 
alternative, the total mass of organic HAP emissions from all surface 
coating operations in the affected source must be less than or equal to 
the total mass of organic HAP emissions that would result if it complied 
separately with all applicable subparts. You must make this comparison 
for the initial compliance period and report it in the Notification of 
Compliance Status as required in Sec. 63.4110(b)(10) and in the 
Notification of Compliance Status required by the other subparts. If you 
choose this alternative, your demonstration of compliance with the other 
subpart constitutes compliance with this subpart.



Sec. 63.4082  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source.
    (b) The affected source is the collection of all of the items listed 
in paragraphs (b)(1) through (4) of this section that are part of the 
large appliance surface coating facility:
    (1) All coating operations as defined in Sec. 63.4181;

[[Page 279]]

    (2) All storage containers and mixing vessels in which coatings, 
thinners, and cleaning materials are stored or mixed;
    (3) All manual and automated equipment and containers used for 
conveying coatings, thinners, and cleaning materials; and
    (4) All storage containers and all manual and automated equipment 
and containers used for conveying waste materials generated by a coating 
operation.
    (c) An affected source is a new affected source if you commenced its 
construction after July 23, 2002, and the construction is of a 
completely new large appliance surface coating facility where previously 
no large appliance surface coating facility had existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.4083  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Secs. 63.4140, 63.4150, 
and 63.4160.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section.
    (1) If the initial startup of your new or reconstructed affected 
source is before July 23, 2002, the compliance date is July 23, 2002.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after July 23, 2002, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is July 25, 
2005.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source, or the date 
the area source becomes a major source, or July 23, 2002, whichever is 
latest.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or July 25, 2005, whichever 
is later.
    (d) You must meet the notification requirements in Sec. 63.4110 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4090  What emission limits must I meet?

    (a) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than 0.13 kilogram per liter (kg/
liter) (1.1 pound per gallon (lb/gal)) of coating solids used during 
each compliance period.
    (b) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no more than 0.022 kg/liter 
(0.18 lb/gal) of coating solids used during each compliance period.



Sec. 63.4091  What are my options for meeting the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable emission limit in 
Sec. 63.4090. To make this determination, you must use at least one of 
the three compliance options listed in paragraphs (a) through (c) of 
this section. You may apply any of the compliance options to an 
individual coating operation or to multiple coating operations as a 
group or to the entire affected source. You may use

[[Page 280]]

different compliance options for different coating operations or at 
different times on the same coating operation. However, you may not use 
different compliance options at the same time on the same coating 
operation. If you switch between compliance options for any coating 
operation or group of coating operations, you must document this switch 
as required by Sec. 63.4130(c), and you must report it in the next 
semiannual compliance report required in Sec. 63.4120.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit in Sec. 63.4090, and that each 
thinner and each cleaning material used contains no organic HAP. You 
must meet all the requirements of Secs. 63.4140, 63.4141, and 63.4142 to 
demonstrate compliance with the emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s), the organic HAP emission rate for the coating 
operation(s) is less than or equal to the applicable emission limit in 
Sec. 63.4090. You must meet all the requirements of Secs. 63.4150, 
63.4151, and 63.4152 to demonstrate compliance with the emission limit 
using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on data on the coatings, thinners, and cleaning materials used in 
the coating operation(s) and the emission reductions achieved by 
emission capture and add-on controls, the organic HAP emission rate for 
the coating operation(s) is less than or equal to the applicable 
emission limit in Sec. 63.4090. If you use this compliance option, you 
must also demonstrate that all emission capture systems and add-on 
control devices for the coating operation(s) meet the operating limits 
required in Sec. 63.4092, except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to 
Sec. 63.4161(h), and that you meet the work practice standards required 
in Sec. 63.4093. You must meet all the requirements of Secs. 63.4160 
through 63.4168 to demonstrate compliance with the emission limits, 
operating limits, and work practice standards using this option.



Sec. 63.4092  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec. 63.4161(h), you must meet the operating limits 
specified in Table 1 to this subpart. These operating limits apply to 
the emission capture and control systems on the coating operation(s) for 
which you use this option, and you must establish the operating limits 
during the performance test according to the requirements in 
Sec. 63.4167. You must meet the operating limits at all times after you 
establish them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the U.S. 
Environmental Protection Agency (EPA) Administrator for approval of 
alternative monitoring under Sec. 63.8(f).



Sec. 63.4093  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option, you 
must develop and implement a work practice plan to minimize organic HAP 
emissions from the storage, mixing, and conveying of coatings, thinners, 
and cleaning materials used in, and waste materials generated by, the 
coating operation(s) for which you use this option; or you must meet an 
alternative standard as provided in paragraph (c) of this section. The 
plan must specify practices and procedures to ensure

[[Page 281]]

that, at a minimum, the elements specified in paragraphs (b)(1) through 
(5) of this section are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers.
    (2) Spills of organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be minimized.
    (3) Organic-HAP-containing coatings, thinners, cleaning materials, 
and waste materials must be conveyed from one location to another in 
closed containers or pipes.
    (4) Mixing vessels which contain organic-HAP-containing coatings and 
other materials must be closed except when adding to, removing, or 
mixing the contents.
    (5) Emissions of organic HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) As provided in Sec. 63.6(g), we, the EPA, may choose to grant 
you permission to use an alternative to the work practice standards in 
this section.

                     General Compliance Requirements



Sec. 63.4100  What are my general requirements for complying with this subpart?

    (a) You must be in compliance with the emission limitations in this 
subpart as specified in paragraphs (a)(1) and (2) of this section.
    (1) Any coating operation(s) for which you use the compliant 
material option or the emission rate without add-on controls option, as 
specified in Sec. 63.4091(a) and (b), must be in compliance with the 
applicable emission limit in Sec. 63.4090 at all times.
    (2) Any coating operation(s) for which you use the emission rate 
with add-on controls option, as specified in Sec. 63.4091(c), must be in 
compliance with the applicable emission limit in Sec. 63.4090 and work 
practice standards in Sec. 63.4093 at all times. Each controlled coating 
operation must be in compliance with the operating limits for emission 
capture systems and add-on control devices required by Sec. 63.4092 at 
all times, except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to Sec. 63.4161(h).
    (b) You must always operate and maintain your affected source, 
including all air pollution control and monitoring equipment you use for 
purposes of complying with this subpart, according to the provisions in 
Sec. 63.6(e)(1)(i).
    (c) If your affected source uses an emission capture system and add-
on control device, you must maintain a log detailing the operation and 
maintenance of the emission capture system, add-on control device, and 
continuous parameter monitors during the period between the compliance 
date specified for your affected source in Sec. 63.4083 and the date 
when the initial emission capture system and add-on control device 
performance tests have been completed as specified in Sec. 63.4160. This 
requirement does not apply to a solvent recovery system for which you 
conduct a liquid-liquid material balance according to Sec. 63.4161(h) in 
lieu of conducting performance tests.
    (d) If your affected source uses an emission capture system and add-
on control device, you must develop and implement a written startup, 
shutdown, and malfunction plan according to the provisions in 
Sec. 63.6(e)(3). The plan must address the startup, shutdown, and 
corrective actions in the event of a malfunction of the emission capture 
system or the add-on control device. The plan must also address any 
coating operation equipment that may cause increased emissions or that 
would affect capture efficiency if the process equipment malfunctions, 
such as conveyors that move parts among enclosures.



Sec. 63.4101  What parts of the General Provisions apply to me?

    Table 2 to this subpart shows which parts of the General Provisions 
in Secs. 63.1 through 63.15 apply to you.

Sec. 63.4120  What reports must I submit?

    You must submit semiannual compliance reports for each affected 
source according to the requirements of this section. The semiannual 
compliance reporting requirements of this section may be satisfied by 
reports required under other parts of the Clean Air Act (CAA), as 
specified in paragraph (a)(5) of this section.
    (a) Unless the Administrator has approved a different schedule for 
submission of reports under Sec. 63.10(a), you must prepare and submit 
each semiannual compliance report according to the dates specified in 
paragraphs (a)(1) through (4) of this section.
    (1) The first semiannual compliance report must cover the first 
semiannual reporting period which begins the day after the end of the 
initial compliance period described in Sec. 63.4140, Sec. 63.4150, or 
Sec. 63.4160 that applies to your affected source and ends on June 30 or 
December 31, whichever date is the first date following the end of the 
initial compliance period.
    (2) Each subsequent semiannual compliance report must cover the 
subsequent semiannual reporting period from January 1 through June 30 or 
the semiannual reporting period from July 1 through December 31.
    (3) Each semiannual compliance report must be postmarked or 
delivered no later than July 31 or January 31, whichever date is the 
first date following the end of the semiannual reporting period.
    (4) For each affected source that is subject to permitting 
regulations pursuant to 40 CFR part 70 or 40 CFR part 71, and if the 
permitting authority has established dates for submitting semiannual 
reports pursuant to 40 CFR 70.6(a)(3)(iii)(A) or 40 CFR 
71.6(a)(3)(iii)(A), you may submit the first and subsequent semiannual 
compliance reports according to the dates the permitting authority has 
established instead of the date specified in paragraph (a)(3) of this 
section.

        Compliance Requirements for the Compliant Material Option



Sec. 63.4140  By what date must I conduct the initial compliance demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 63.4141. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date. If the compliance date occurs on any 
day other than the first day of a month, then the initial compliance 
period extends through the end of that month plus the next month. The 
initial compliance demonstration includes the determination according to 
Sec. 63.4141 and supporting documentation showing that, during the 
initial compliance period, you used no coating with an organic HAP 
content that exceeded the applicable emission limit in Sec. 63.4090, and 
that you used no thinners or cleaning materials that contained organic 
HAP.



Sec. 63.4141  How do I demonstrate initial compliance with the emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected

[[Page 289]]

source. You must use either the emission rate without add-on controls 
option or the emission rate with add-on controls option for any coating 
operation(s) in the affected source for which you do not use this 
option. To demonstrate initial compliance using the compliant material 
option, the coating operation or group of coating operations must use no 
coating with an organic HAP content that exceeds the applicable emission 
limit in Sec. 63.4090 and must use no thinner or cleaning material that 
contains organic HAP, as determined according to this section during the 
initial compliance period. Any coating operation(s) for which you use 
the compliant material option is not required to meet the operating 
limits or work practice standards required in Secs. 63.4092 and 63.4093, 
respectively. To demonstrate initial compliance with the emission 
limitations using the compliant material option, you must meet all the 
requirements of this section for the coating operation(s) using this 
option. Use the procedures in this section on each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration. You do not need to 
redetermine the HAP content of coatings, thinners, or cleaning materials 
that have been reclaimed onsite and reused in the coating operation(s) 
for which you use the compliant material option, provided these 
materials in their condition as received were demonstrated to comply 
with the compliant material option. If the mass fraction of organic HAP 
of a coating equals zero, determined according to paragraph (a) of this 
section, and you use the compliant material option, you are not required 
to comply with paragraphs (b) and (c) of this section for that coating.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data if they represent each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other organic HAP compounds. For example, if toluene 
(not an OSHA carcinogen) is 0.5 percent of the material by mass, you do 
not have to count it. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence.

[[Page 290]]

    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 of this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries, and you may only use Table 4 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 3, and you only know whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 test indicate higher 
values than those listed on Table 3 or 4 of this subpart, the Method 311 
results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test, by information provided by the 
supplier or the manufacturer of the material, or by calculation as 
specified in paragraphs (b)(1) through (3) of this section.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings,'' or D6093-97, 
``Standard Test Method for Percent Volume Nonvolatile Matter in Clear or 
Pigmented Coatings Using a Helium Gas Pycnometer'' (incorporated by 
reference, see Sec. 63.14) to determine the volume fraction of coating 
solids for each coating. Divide the nonvolatile volume percent obtained 
with the methods by 100 to calculate volume fraction of coating solids.

You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.018

Where:

Vs = volume fraction of coating solids, liters coating solids 
per liter coating.

results using ASTM Method D1475-98, ``Standard Test Method for Density 
of Liquid Coatings, Inks, and Related Products'' (incorporated by 
reference, see Sec. 63.14) information from the supplier or manufacturer 
of the material, or reference sources providing density or specific 
gravity data for pure materials. If there is disagreement between ASTM 
Method D1475-98 test results and other information sources, the test 
results will take precedence.

    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-98, ``Standard Test Method for Density of Liquid 
Coatings, Inks, and Related Products'' (incorporated by reference, see

organic HAP content, kg organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section, except

[[Page 291]]

that if the mass fraction of organic HAP equals zero, then the organic 
HAP content also equals zero and you are not required to use Equation 2 
to calculate the organic HAP content:

compliance period must be less than or equal to the applicable emission 
limit in Sec. 63.4090; and each thinner and cleaning material used 
during the initial compliance period must contain no organic HAP, 
determined according to paragraph (a) of this section. You must keep all 
records required by Secs. 63.4130 and 63.4131. As part of the 
Notification of Compliance Status required in Sec. 63.4110, you must 
identify the coating operation(s) for which you used the compliant 
material option and submit a statement that the coating operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you used no coatings for which the organic HAP 
content exceeds the applicable emission limit in Sec. 63.4090, and you 
used no thinners or cleaning materials that contain organic HAP, 
determined according to paragraph (a) of this section.



Sec. 63.4142  How do I demonstrate continuous compliance with the emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must use no coating for which the organic HAP content, 
determined according to Sec. 63.4141(d), exceeds the applicable emission 
limit in Sec. 63.4090, and use no thinner or cleaning material that 
contains organic HAP, determined according to Sec. 63.4141(a). Each 
month following the initial compliance period described in Sec. 63.4140 
is a compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(d).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4120, you must submit a statement that you were in compliance

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 63.4151. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date. If the compliance date occurs on any 
day other than the first day of a month, then the initial compliance 
period extends through the end of that month plus the next month. The 
initial compliance demonstration includes the calculations according to 
Sec. 63.4151 and supporting documentation showing that the organic HAP 
emission rate for the initial compliance period was equal to or less 
than the applicable emission limit in Sec. 63.4090.

[[Page 292]]



Sec. 63.4151  How do I demonstrate initial compliance with the emission limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You must use either the compliant material option or the 
emission rate with add-on controls option for any coating operation(s) 
in the affected source for which you do not use this option. To 
demonstrate initial compliance using the emission rate without add-on 
controls option, the coating operation(s) must meet the applicable 
emission limit in Sec. 63.4090 but not the operating limits or work 
practice standards in Secs. 63.4092 and 63.4093, respectively, during 
the initial compliance period. You must meet all of the requirements of 
this section to demonstrate initial compliance with the applicable 
emission limit in Sec. 63.4090 for the coating operation(s). When 
calculating the organic HAP emission rate according to this section, do 
not include any coatings, thinners, or cleaning materials used on 
coating operations for which you use the compliant material option or 
the emission rate with add-on controls option. You do not need to 
redetermine the mass of organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed onsite and reused in the coating 
operation(s) for which you use the emission rate without add-on controls 
option.
    (a) Determine the mass fraction of organic HAP for each material.

period. Determine the volume (liters) of each coating, thinner, and 
cleaning material used during the compliance period by measurement or 
usage records.
    (e) Calculate the mass of organic HAP emissions during the 
compliance period. The mass of organic HAP emissions is the combined 
mass of organic HAP contained in all coatings, thinners, and cleaning 
materials used during the compliance period minus the organic HAP in 
certain waste materials. Calculate it using Equation 1 of this section.

sent to a TSDF. If you choose to account for the mass of organic HAP 
contained in waste materials sent or designated for shipment to a 
hazardous waste TSDF in the calculation of the mass of organic HAP 
emissions (Equation 1 of this section), then you must determine it 
according to paragraphs (e)(4)(i) through (v) of this section.
    (i) You may include in the determination of organic HAP in waste 
materials only the waste materials that are generated by coating 
operations for which you use Equation 1 of this section and that will be 
treated or disposed of by a facility that is regulated as a TSDF under 
40 CFR part 262, 264, 265, or 266. The TSDF may be either off-site or 
on-site. You may not include in the determination the organic HAP 
contained in wastewater.
    (ii) You must determine either the amount of waste materials sent to 
a TSDF during the compliance period or the amount collected and stored 
during the compliance period and designated for future transport to a 
TSDF. Do not include in your determination any waste materials sent to a 
TSDF during a compliance period if you have already included them in the 
amount collected and stored during that compliance period or a previous 
compliance period.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(4)(ii) of this section.

compliance period. Determine the total volume of coating solids used, 
liters, which is the combined volume of coating solids for all of the 
coatings used during the compliance period, using Equation 2 of this 
section.

    during the compliance period, kg, as calculated by Equation 1 of 
    this section.
Vst = total volume coating solids used during the compliance 
    period, liters, as calculated by Equation 2 of this section.

    (h) The organic HAP emission rate for the initial compliance period 
must be less than or equal to the applicable emission limit in 
Sec. 63.4090. You must keep all records as required by Secs. 63.4130 and 
63.4131. As part of the Notification of Compliance Status required by 
Sec. 63.4110, you must identify the coating operation(s) for which you 
used the emission rate without add-on controls option and submit a 
statement that the coating operation(s) was (were) in compliance with 
the emission limitations during the initial compliance period because 
the organic HAP emission rate was less than or equal to the applicable 
emission limit in Sec. 63.4090.



Sec. 63.4152  How do I demonstrate continuous compliance with the emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, determined according to Sec. 63.4151(a) 
through (g), must be less than or equal to the applicable emission limit 
in Sec. 63.4090. Each month following the initial compliance period 
described in Sec. 63.4150 is a compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4090, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(e).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4120, you must submit a statement that you were in compliance 
with the emission limitations during the reporting period because the 
organic HAP emission rate for each compliance period was less than or 
equal to the applicable emission limit in Sec. 63.4090.
    (d) You must maintain records as specified in Secs. 63.4130 and 
63.4131.

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.4160  By what date must I conduct performance tests and other initial compliance demonstrations?

    (a) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (a)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
you use to demonstrate compliance must be installed and operating no

initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date. If the compliance date occurs on any 
day other than the first day of a month, then the initial compliance 
period extends through the end of that month plus the next month. The 
initial compliance demonstration includes the results of emission 
capture system and add-on control device performance tests conducted 
according to Secs. 63.4164, 63.4165, and 63.4166; results of liquid-
liquid material balances conducted according to Sec. 63.4161(h);

tests and the results of the continuous parameter monitoring required by 
Sec. 63.4168; and documentation of whether you developed and implemented 
the work practice plan required by Sec. 63.4093.
    (b) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (b)(1) through (4) this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
you use to demonstrate compliance must be installed and operating no 
later than the applicable compliance date specified in Sec. 63.4183. 
Except for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec. 63.4161(h), you must conduct a 
performance test of each capture system and add-on control device 
according to the procedures in Secs. 63.4164, 63.4165, and 63.4166, and 
establish the operating limits required by Sec. 63.4092 no later than 
180 days after the applicable compliance date specified in Sec. 63.4183. 
For a solvent recovery system for which you conduct liquid-liquid

Sec. 63.4083.
    (3) You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec. 63.4161. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4083 and ends on the last day of the first full 
month after the compliance date, or the date you conduct the performance 
tests of the emission capture systems and add-on control devices, or 
initiate the first liquid-liquid material balance for a solvent recovery 
system; whichever is later. The initial compliance demonstration 
includes the results of emission capture system and add-on control 
device performance tests conducted according to Secs. 63.4164, 63.4165,

    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by 
Sec. 63.4092 until after you have completed the performance tests 
specified in paragraph (b)(1) of this section. Instead, you must 
maintain a log detailing the operation and maintenance of the emission 
capture system, add-on control device, and continuous

[[Page 296]]

parameter monitors during the period between the compliance date and the 
performance test. You must begin complying with the operating limits for 
your affected source on the date you complete the performance tests 
specified in paragraph (b)(1) of this section. This requirement does not 
apply to solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec. 63.4161(h).



Sec. 63.4161  How do I demonstrate initial compliance?

    You may use the emission rate with add-on controls option for any 
coating operation, for any group of coating operations in the affected 
source, or for all of the coating operations in the affected source. You 
may include both controlled and uncontrolled coating operations in a 
group for which you use this option. You must use either the compliant 
material option or the emission rate without add-on controls option for 
any coating operation(s) in the affected source for which you do not use 
this option. To demonstrate initial compliance, the coating operation(s) 
for which you use the emission rate with add-on controls option must 
meet the applicable emission limit in Sec. 63.4090 and the work practice 
standards required in Sec. 63.4093; and each controlled coating 
operation must meet the operating limits required in Sec. 63.4092. You 
must meet all the requirements of this section to demonstrate initial 
compliance with the emission limitations. When calculating the organic 
HAP emission rate according to this section, do not include any 
coatings, thinners, or cleaning materials used on coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option. You do not need to redetermine the mass of 
organic HAP in coatings, thinners, or cleaning materials that have been 
reclaimed onsite and reused in the coating operation(s) for which you 
use the emission rate with add-on controls option.
    (a) Except as provided in Sec. 63.4160(b)(4) and except for solvent 
recovery systems for which you conduct liquid-liquid material balances 
according to the requirements of Sec. 63.4161(h), you must establish and 
demonstrate continuous compliance during the initial compliance period 
with the operating limits required by Sec. 63.4092, using the procedures 
specified in Secs. 63.4167 and 63.4168.
    (b) You must develop, implement, and document your implementation of 
the work practice plan required by Sec. 63.4093 during the initial 
compliance period as specified in Sec. 63.4130.
    (c) You must follow the procedures in paragraphs (d) through (l) of 
this section to demonstrate compliance with the applicable emission 
limit in Sec. 63.4090.
    (d) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4151(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during the compliance period, and the volume 
fraction of coating solids for each coating used during the compliance 
period.
    (e) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4151, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during the compliance period in 
the coating operation or group of coating operations for which you use 
the emission rate with add-on controls option.
    (f) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during the compliance period. The 
emissions reduction determination quantifies the total organic HAP 
emissions that pass through the emission capture system and are 
destroyed or removed by the add-on control device. Use the procedures in 
paragraph (g) of this section to calculate the mass of organic HAP 
emissions reduction for each controlled coating operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances. 
For each controlled coating operation using a solvent recovery system 
for which you

[[Page 297]]

conduct a liquid-liquid material balance, use the procedures in 
paragraph (h) of this section to calculate the organic HAP emissions 
reduction.
    (g) Calculate the organic HAP emissions reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate organic HAP emissions 
reduction, using Equation 1 of this section, by applying the emission 
capture system efficiency and add-on control device efficiency to the 
mass of organic HAP contained in the coatings, thinners, and cleaning 
materials that are used in the coating operation served by the emission 
capture system and add-on control device during the compliance period. 
For any period of time a deviation specified in Sec. 63.4163(c) or (d) 
occurs in the controlled coating operation, including a deviation during 
a period of startup, shutdown, or malfunction, you must assume zero 
efficiency for the emission capture system and add-on control device. 
For the purposes of completing the compliance calculations, you must 
treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation. You must not include those materials 
in the calculations of organic HAP emissions reduction in Equation 1 of 
this section.

Notification of Compliance Status required by Sec. 63.4110, you must 
identify the coating operation(s) for which you used the emission rate 
with add-on controls option and submit a statement that the coating 
operation(s) was (were) in compliance with the emission limitations 
during the initial compliance period because the organic HAP emission 
rate was less than or equal to the applicable emission limit in 
Sec. 63.4090, and you achieved the operating limits required by 
Sec. 63.4092 and the work practice standards required by Sec. 63.4093.



Sec. 63.4162  [Reserved]



Sec. 63.4163  How do I demonstrate continuous compliance with the emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4090, the organic HAP emission rate for each 
compliance period determined according to the procedures in Sec. 63.4161 
must be equal to or less than the applicable emission limit in 
Sec. 63.4090. Each month following the initial compliance period 
described in Sec. 63.4160 is a compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4090, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Secs. 63.4110(b)(6) and 63.4120(g).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4092 that applies to you as specified in Table 
1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Secs. 63.4110(b)(6) and 
63.4120(g).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4161, you 
must treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation. You must not include those materials 
in the calculation of organic HAP emissions reductions in Equation 1 of 
Sec. 63.4161.

[[Page 301]]

    (d) You must meet the requirements for bypass lines in 
Sec. 63.4168(b). If any bypass line is opened and emissions are diverted 
to the atmosphere when the coating operation is running, this is a 
deviation that must be reported as specified in Secs. 63.4110(b)(6) and 
63.4120(g). For the purposes of completing the compliance calculations 
specified in Sec. 63.4161, you must treat the materials used during a 
deviation on a controlled coating operation as if they were used on an 
uncontrolled coating operation for the time period of the deviation. You 
must not include those materials in the calculation of organic HAP 
emissions reductions in Equation 1 of Sec. 63.4161.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4093. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4130(k)(9), this is a deviation from the 
work practice standards that must be reported as specified in 
Secs. 63.4110(b)(6) and 63.4120(g).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4120, you must submit a statement that you were in compliance 
with the emission limitations during the reporting period because the 
organic HAP emission rate for each compliance period was less than or 
equal to the applicable emission limit in Sec. 63.4090, and you achieved 
the operating limits required by Sec. 63.4092 and the work practice 
standards required by Sec. 63.4093 during each compliance period.
    (g) During periods of startup, shutdown, and malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency, you must 
operate in accordance with the SSMP required by Sec. 63.4100(d).
    (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency are not 
violations if you demonstrate to the Administrator's satisfaction that 
you were operating in accordance with the SSMP. 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).
    (i) [Reserved]
    (j) You must maintain records as specified in Secs. 63.4130 and 
63.4131.



Sec. 63.4164  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4160 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction and periods of nonoperation do not constitute 
representative conditions. You must record the process information that 
is necessary to document operating conditions during the test and 
explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4165 and of an add-on 
control device according to the requirements in Sec. 63.4166.
    (c) The performance test to determine add-on control device organic 
HAP destruction or removal efficiency must consist of three runs as 
specified in Sec. 63.7(e)(3) and each run must last at least 1 hour.

[[Page 302]]



Sec. 63.4165  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4160.
    (a) You may assume the capture system efficiency is 100 percent if 
both of the conditions in paragraphs (a)(1) and (2) of this section are 
met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system and the removal or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) If the capture system does not meet both of the criteria in 
paragraphs (a)(1) and (2) of this section, then you must use one of the 
three protocols described in paragraphs (c), (d), and (e) of this 
section to measure capture efficiency. The capture efficiency 
measurements use TVH capture efficiency as a surrogate for organic HAP 
capture efficiency. For the protocols in paragraphs (c) and (d) of this 
section, the capture efficiency measurement must consist of three test 
runs. Each test run must be at least 3 hours duration or the length of a 
production run, whichever is longer, up to 8 hours. For the purposes of 
this test, a production run means the time required for a single part to 
go from the beginning to the end of production which includes surface 
preparation activities and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation, to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions for routing to an add-on control device, such as the entrance 
and exit areas of an oven or spray booth, must also be inside the 
enclosure. The enclosure must meet the applicable definition of a 
temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner, and cleaning material used in the coating operation during each 
capture efficiency test run. To make the determination, substitute TVH 
for each occurrence of the term VOC in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR23JY02.013

Where:

TVHused = total mass of TVH liquid input from all coatings, 
thinners,

[[Page 303]]

and cleaning materials used in the coating operation during the capture 
efficiency test run, kg.
TVHi = mass fraction of TVH in coating, thinner, or cleaning 
material, i, that is used in the coating operation during the capture 
efficiency test run, kg TVH per kg material.
Voli = total volume of coating, thinner, or cleaning 
material, i, used in the coating operation during the capture efficiency 
test run, liters.
Di = density of coating, thinner, or cleaning material, i, kg 
material per liter material.
n = number of different coatings, thinners, and cleaning materials used 
in the coating operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.014

Where:

CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHused = total mass of TVH liquid input used in the coating 
operation during the capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied and all areas where emissions from these applied coatings 
and materials subsequently occur such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on

[[Page 304]]

control device. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure other than the coating 
operation for which capture efficiency is being determined must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23JY02.015

Where:

CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHcaptured = total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, kg.
TVHuncaptured = total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4166  How do I determine the add-on control device emission destruction or removal efficiency?

    (a) For all types of add-on control devices, use the test methods as 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME, PTC 19.10-1981, ``Flue and Exhaust Gas Analyses'' 
(incorporated by reference, see Sec. 63.14).

[[Page 305]]

    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high-volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.

Mf = total gaseous organic emissions mass flow rate, kg/per 
hour (h).
Cc = concentration of organic compounds as carbon in the vent 
gas, as determined by Method 25 or Method 25A, parts per million by 
volume (ppmv), dry basis.
Qsd = volumetric flow rate of gases entering or exiting the 
add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, 
dry standard cubic meters/hour (dscm/h).
0.0416 = conversion factor for molar volume, kg-moles per cubic meter 
(mol/m \3\) (@ 293 Kelvin (K) and 760 millimeters of mercury (mm Hg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section.

DRE = add-on control device organic emissions destruction or removal 
efficiency, percent.

inlet(s) to the add-on control device, using Equation 1 of this section, 
kg/h.
Mfo = total gaseous organic emissions mass flow rate at the 
outlet(s) of the add-on control device, using Equation 1 of this 
section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4167  How do I establish the emission capture system and add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4160 and described 
in Secs. 63.4164, 63.4165, and 63.4166, you must establish the operating 
limits required by

combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.

average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature just before the 
catalyst bed and implement a site-specific inspection and maintenance 
plan for your catalytic oxidizer as specified in paragraph (b)(4) of 
this section. During the performance test, you must monitor and record 
the temperature just before the catalyst bed at least once every 15

assembly and fuel supply lines for problems and, as necessary, adjusting 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4166.

(e.g., steam or nitrogen) mass flow for each regeneration cycle and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon absorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.

[[Page 307]]

    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.

for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4165(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by 
Sec. 63.4160 and described in Secs. 63.4164 and 63.4165, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.4168  What are the requirements for continuous parameter monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation except as specified in paragraph (a)(6) of this 
section.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device

[[Page 308]]

parameter data recorded during monitoring malfunctions, associated 
repairs, out-of-control periods, or required quality assurance or 
control activities when calculating data averages. You must use all the 
data collected during all other periods in calculating the data averages 
for determining compliance with the emission capture system and add-on 
control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Except for periods of required 
quality assurance or control activities, any period during which the 
CPMS fails to operate and record data continuously as required by 
paragraph (a)(1) of this section, or generates data that cannot be 
included in calculating averages as specified in paragraph (a)(6) of 
this section, is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must comply with the 
requirements of paragraphs (a)(3) through (5) and (b)(1) and (2) of this 
section for each emission capture system that contains bypass lines that

atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (non-diverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shutdown the coating operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4120.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (a) and (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor in 
the gas stream immediately before the catalyst bed, and if you establish 
operating

Subpart OOOO--National Emission Standards for Hazardous Air Pollutants: 
       Printing, Coating, and Dyeing of Fabrics and Other Textiles

    Source: 68 FR 32189, May 29, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for fabric and other textiles printing, coating 
and dyeing operations. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the emission 
limitations.



Sec. 63.4281  Am I subject to this subpart?

    (a) Except as provided in paragraphs (c) and (d) of this section, 
the source category to which this subpart applies is the printing, 
coating, slashing, dyeing or finishing of fabric and other textiles, and 
it includes the subcategories listed in paragraphs (a)(1) through (3) of 
this section.
    (1) The coating and printing subcategory includes any operation that 
coats or prints fabric or other textiles. Coating and printing 
operations are defined in Sec. 63.4371. Coated and printed substrates 
are used in products including, but not limited to, architectural 
structures, apparel, flexible hoses, hot-air balloons, lightweight 
liners, luggage, military fabric, rainwear, sheets, tents, threads and 
V-belts. The coating and printing subcategory includes any fabric or 
other textile web coating line that also performs coating on another 
substrate unless such coating is specifically excluded from this subpart 
by another NESHAP in this part or is exempted from the requirements of 
this subpart based on the criteria in paragraph (e) of this section. Web 
coating lines exclusively dedicated to coating

[[Page 319]]

or printing fabric and other textiles are subject to this subpart.
    (2) The slashing subcategory includes any operation with slashing 
operations as defined in Sec. 63.4371. In the slashing process, sizing 
compounds are applied to warp yarn to bind the fiber together and 
stiffen the yarn to provide abrasion resistance during weaving.
    (3) The dyeing and finishing subcategory includes any operation that 
dyes or finishes a fabric or other textiles. Dyeing and finishing 
operations are defined in Sec. 63.4371. Dyed and finished textiles are 
used in a wide range of products including, but not limited to, apparel, 
carpets, high-performance industrial fabrics, luggage, military fabrics, 
outer wear, sheets, towels, and threads.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source, as defined in Sec. 63.4282, 
that is a major source, is located at a major source, or is part of a 
major source of hazardous air pollutants (HAP). Major source is defined 
in Sec. 63.2 of this part.
    (c) This subpart does not apply to coating, printing, slashing, 
dyeing, or finishing operations that meet any of the criteria of 
paragraphs (c)(1) through (5) of this section.
    (1) Coating and printing, slashing, or dyeing and finishing 
operations conducted at a source that uses only regulated materials that 
contain no organic HAP as defined in Sec. 63.4371.
    (2) Coating, printing, slashing, dyeing, or finishing that occurs at 
research or laboratory operations or that is part of janitorial, 
building, and facility maintenance operations.
    (3) Coating, printing, slashing, dyeing, or finishing operations 
used by a facility and not for commerce, unless organic HAP emissions 
from the coating, printing, slashing, dyeing or finishing operations are 
as high as the major source HAP emissions specified in paragraph (b) of 
this section.
    (4) Fabric and other textile substrate web coating or printing 
operations conducted at ambient temperatures that do not involve drying 
or curing equipment such as ovens, tenter frames, steam cans, or dryers.
    (5) Coating, printing, slashing, dyeing, or finishing operations 
performed on-site at installations owned or operated by the Armed Forces 
of the United States (including the Coast Guard and the National Guard 
of any State).
    (d) Web coating lines specified in paragraphs (d)(1) through (3) of 
this section are not part of the affected source of this subpart.
    (1) Any web coating operation that is part of the affected source of 
subpart JJJJ of this part (national emission standards for hazardous air 
pollutants for paper and other web coating). This would include any web 
coating line that coats both a paper and other web substrate and a 
fabric or other textile substrate for use in flexible packaging, 
pressure sensitive tape and abrasive materials, or any web coating line 
laminating a fabric substrate to paper.
    (2) Any web coating operation that is part of the affected source of 
subpart XXXX of this part (NESHAP for tire manufacturing). This would 
include any web coating line that applies coatings to both tire cord and 
to textile cord used in the production of belts and hoses.
    (3) Coating, slashing, dyeing, or finishing operations at a 
synthetic fiber manufacturing facility included in the affected source 
of another subpart of this part, such as subpart F (NESHAP for the 
synthetic organic chemical manufacturing industry) or subpart JJJ 
(NESHAP for group IV polymers and resins).
    (e) Any web coating line that coats both fabric and other textiles, 
and another substrate such as paper, must comply with the subpart of 
this part that applies to the predominant activity conducted on the 
affected source. Predominant activity for this subpart is 90 percent of 
the mass of substrate coated during the compliance period. (For example, 
a web coating line that coats 90 percent or more of a paper substrate, 
and 10 percent or less of a fabric or other textile substrate, would be 
subject to 40 CFR 63, subpart JJJJ.)

                          Emission Limitations



Sec. 63.4290  What emission limits must I meet?

    You must meet the emission limit for the subcategory or 
subcategories present in your facility. The three subcategories are: Web 
coating and printing, slashing, and dyeing and finishing. Table 1 to 
this subpart presents the emission limits for a new or reconstructed 
affected source and for an existing affected source in each subcategory.



Sec. 63.4291  What are my options for meeting the emission limits?

    You must include all regulated materials (as defined in 
Sec. 63.4371) used in the affected source when determining whether the 
organic HAP emission rate is equal to or less than the applicable 
emission limit in Table 1 to this subpart. To make this determination, 
you must use at least one of the compliance options for the subcategory 
listed in paragraphs (a) through (c) of this section.
    (a) Web coating and printing. You may apply any one of the 
compliance options in paragraphs (a)(1) through (5) of this section to 
an individual web coating/printing operation, or to multiple web 
coating/printing operations in the affected source as a group, or to the 
entire affected source in the web coating and printing subcategory. You 
may use different compliance options for different web coating/printing 
operations or at different times on the same web coating/printing 
operation. However, you may not use different compliance options at the 
same time on the same web coating/printing operation. If you switch 
between compliance options for any web coating/printing operation or 
group of operations, you must document this switch as required by 
Sec. 63.4312(c), and you must report it in the next semiannual 
compliance report required in Sec. 63.4311.
    (1) Compliant material option. Demonstrate that the organic HAP 
content, as purchased, of each coating and printing material applied in 
the web coating/printing operation(s) is less

        Compliance Requirements for the Compliant Material Option



Sec. 63.4320  By what date must I conduct the initial compliance demonstration?

    You must complete the compliance demonstration for the initial 
compliance period according to the requirements in Sec. 63.4321. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4283 and ends on the last day of the first full 
month after the compliance date. The initial compliance demonstration 
includes the calculations according to Sec. 63.4321 and supporting 
documentation showing that, during the initial compliance period, the 
organic HAP content of each coating and printing material you applied 
and the mass fraction of organic HAP in each slashing, dyeing, and 
finishing material you applied did not exceed the applicable limit in 
Table 1 to this subpart, and documentation that in web coating/printing 
operations you applied only thinners and cleaners that contained no 
organic HAP as defined in Sec. 63.4371.



Sec. 63.4321  How do I demonstrate initial compliance with the emission limitations?

    (a) You may use the compliant material option for any individual web 
coating/printing operation, for any group of web coating/printing 
operations in the affected source, or for all the web coating/printing 
operations in the affected source. You must use either the emission rate 
without add-on controls option, the emission rate with add-on

[[Page 335]]

controls option, the organic HAP overall control efficiency option, or 
the oxidizer outlet organic HAP concentration option for any web 
coating/printing operation(s) in the affected source for which you do 
not use this option. For a web coating/printing affected source to 
demonstrate initial compliance using the compliant material option, the 
web coating/printing operation or group of web coating/printing 
operations must apply no coating or printing material with an organic 
HAP content that exceeds the applicable emission limit in Table 1 to 
this subpart and must apply only thinning or cleaning material that 
contains no organic HAP, as defined in Sec. 63.4371.
    (b) You must use the compliant material option for each slashing 
affected source, as required in Table 1 to this subpart. For a slashing 
affected source to demonstrate initial compliance using the compliant 
material option, the slashing operation or group of slashing operations 
must apply only slashing material with no organic HAP as defined in 
Sec. 63.4371.
    (c) You may use the compliant material option for any individual 
dyeing/finishing operation, for any group of dyeing/finishing operations 
in the affected source, or for all the dyeing/finishing operations in 
the affected source. You must use either the emission rate without add-
on controls option or the emission rate with add-on controls option for 
any dyeing/finishing operations in the affected source for which you do 
not use this option. You may not use the compliant material option for 
any dyeing/finishing operation in a dyeing/finishing affected source for 
which you use the equivalent emission rate option. For a dyeing/
finishing affected source to demonstrate initial compliance using the 
compliant material option, the dyeing/finishing operation or group of 
dyeing/finishing operations must apply no dyeing or finishing material 
with a mass fraction of organic HAP that exceeds the applicable emission 
limit in Table 1 to this subpart.
    (d) Any web coating/printing operation, slashing operation, or 
dyeing/finishing operation for which you use the compliant material 
option is not required to meet the operating limits or work practice 
standards required in Secs. 63.4292 and 63.4293, respectively.
    (e) To demonstrate initial compliance with the emission limitations 
using the compliant material option, you must meet all the requirements 
of this section for any web coating/printing operation, slashing 
operation, or dyeing/finishing operation using this option. Use the 
applicable procedures in this section on each regulated material in the 
condition it is in when it is received from its manufacturer or supplier 
and prior to any alteration. You do not need to redetermine the organic 
HAP content of regulated materials that are reclaimed onsite and reused 
in the web coating/printing operation, slashing operation, or dyeing/
finishing operation for which you use the compliant material option, 
provided these regulated materials in their condition as received were 
demonstrated to comply with the compliant material option.
    (1) Determine the mass fraction of organic HAP for each material. 
You must determine the mass fraction of organic HAP for each regulated 
material applied during the compliance period by using one of the 
options in paragraphs (e)(1)(i) through (v) of this section. You must 
use the option in paragraph (e)(1)(iv) of this section for each 
printing, slashing, dyeing, or finishing material applied during the 
compliance period.
    (i) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (e)(1)(i)(A) and (B) of this section when 
performing a Method 311 test.
    (A) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you don't have to count it. Express the 
mass fraction of each organic HAP you count as a value truncated to no 
more than four places after the decimal point (e.g., 0.3791).

[[Page 336]]

    (B) Calculate the total mass fraction of organic HAP in the 
regulated material being tested by adding up the individual organic HAP 
mass fractions and truncating the result to no more than three places 
after the decimal point (e.g., 0.763).
    (ii) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
to determine the mass fraction of nonaqueous volatile matter and use 
that value as a substitute for mass fraction of organic HAP. For a 
multi-component coating with reactive chemicals, you may use Method 24 
on the coating as applied to determine the mass fraction of nonaqueous 
volatile matter and use that value as a substitute for the mass fraction 
of organic HAP determined from the sum of organic HAP in each component.
    (iii) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP, mass fraction of solids, 
or fraction of organic HAP emitted from a reactive coating once the 
Administrator has approved it. You must follow the procedure in 
Sec. 63.7(f) to submit an alternative test method for approval.
    (iv) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (e)(1)(i) through (iii) of this section, 
such as manufacturer's formulation data, if it represents each organic 
HAP that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other compounds. For example, if toluene (not an OSHA 
carcinogen) is 0.5 percent of the material by mass, you do not have to 
count it. If there is a disagreement between such information and 
results of a test conducted according to paragraphs (e)(1)(i) through 
(iii) of this section on coating, thinning, or cleaning material, then 
the test method results will take precedence. Information from the 
supplier or manufacturer of the printing, slashing, dyeing, or finishing 
material is sufficient for determining the mass fraction of organic HAP.
    (v) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 4 or 5 to this subpart. If you use the 
tables, you must use the values in Table 4 for all solvent blends that 
match Table 4 entries, and you may only use Table 5 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 4 and you only know whether the blend is aliphatic or aromatic. 
However, if the results of a Method 311 test indicate higher values than 
those listed on Table 4 or 5 to this subpart, the Method 311 results 
will take precedence.
    (2) Determine the mass fraction of solids for each coating and 
printing material. You must determine the mass fraction of solids (kg of 
solids per kg of coating or printing material) for each coating material 
applied during the compliance period by a test or by information 
provided by the supplier or the manufacturer of the material, as 
specified in paragraphs (e)(2)(i) through (iii) of this section. If test 
results obtained according to paragraph (e)(2)(i) or (ii) of this 
section for a coating material do not agree with the information 
obtained under paragraph (e)(2)(iii) of this section, the test results 
will take precedence. To determine mass fraction of solids for each 
printing material applied during the compliance period, you should use 
information provided by the supplier or manufacturer of the material, as 
specified in paragraph (e)(2)(iii) of this section.
    (i) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
for determining the mass fraction of solids of coating materials.
    (ii) Alternative method. You may use an alternative test method for 
determining solids content of each coating material once the 
Administrator has approved it. You must follow the procedure in 
Sec. 63.7(f) to submit an alternative test method for approval.
    (iii) Information from the supplier or manufacturer of the material. 
You may obtain the mass fraction of solids for

[[Page 337]]

each coating and printing material from the supplier or manufacturer. If 
there is disagreement between such information and the test method 
results for a coating material, then the test method results will take 
precedence.
    (3) Calculate the organic HAP content of each coating or printing 
material. Calculate the organic HAP content, kg organic HAP per kg of 
solids, of each coating and printing material applied during the 
compliance period, using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.000

Where:

Hc = Organic HAP content of the coating or printing material, 
kg organic HAP per kg solids in the coating or printing material.
Wc = Mass fraction of organic HAP in the coating or printing 
material, kg organic HAP per kg material, determined according to 
paragraph (e)(1) of this section.
Wf = Mass fraction of solids in coating or printing material, 
kg solids per kg of coating or printing material, determined according 
to paragraph (e)(2) of this section.

    (4) Compliance demonstration. The calculated organic HAP content for 
each coating and printing material applied during the initial compliance 
period must be less than or equal to the applicable emission limit in 
Table 1 to this subpart, and each thinning and cleaning material applied 
during the initial compliance period must contain no organic HAP as 
defined in Sec. 63.4371. Each slashing material applied during the 
initial compliance period must contain no organic HAP as defined in 
Sec. 63.4371. The mass fraction of organic HAP for each dyeing and 
finishing material applied during the initial compliance period, 
determined according to paragraph (e)(1)(iv) of this section, must be 
less than or equal to the applicable emission limit in Table 1 to this 
subpart. You must keep all records required by Secs. 63.4312 and 
63.4313. As part of the Notification of Compliance Status required in 
Sec. 63.4310, you must:
    (i) Identify any web coating/printing operation, slashing operation, 
and dyeing/finishing operation for which you used the compliant material 
option;
    (ii) Submit a statement that the web coating/printing operation(s) 
was (were) in compliance with the emission limitations during the 
initial compliance period because you applied no coating and printing 
material for which the organic HAP content exceeds the applicable 
emission limit in Table 1 to this subpart, and you applied only thinning 
materials and cleaning materials that contained no organic HAP, as 
defined in Sec. 63.4371;
    (iii) Submit a statement that the slashing operation(s) was (were) 
in compliance with the emission limitations during the initial 
compliance period because you applied only slashing materials that 
contained no organic HAP, as defined in Sec. 63.4371; and
    (iv) Submit a statement that the dyeing/finishing operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you applied no dyeing and finishing material 
for which the mass fraction of organic HAP exceeds the applicable 
emission limit in Table 1 to this subpart.



Sec. 63.4322  How do I demonstrate continuous compliance with the emission limitations?

    (a) For each compliance period, to demonstrate continuous 
compliance, you must apply no coating or printing material for which the 
organic HAP content determined using Equation 1 of Sec. 63.4321, exceeds 
the applicable emission limit in Table 1 to this subpart. For each 
compliance period, to demonstrate continuous compliance, you must apply 
only slashing material that contains no organic HAP as defined in 
Sec. 63.4371. For each compliance period, to demonstrate continuous 
compliance, you must apply no dyeing or finishing material for which the 
mass fraction of organic HAP, determined according to the requirements 
of Sec. 63.4321(e)(1)(iv), exceeds the applicable emission limit in 
Table 1 to this subpart. For each compliance period, you must apply only 
thinning or cleaning materials that contain no organic HAP (as defined 
in Sec. 63.4371) in a coating/printing affected source. Each month 
following the initial compliance period described in Sec. 63.4320 is a 
compliance period.

[[Page 338]]

    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the application of any regulated material 
that does not meet the criteria specified in paragraph (a) of this 
section is a deviation from the emission limitations that must be 
reported as specified in Secs. 63.4310(c)(6) and 63.4311(a)(5).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4311, you must identify any web coating/printing operation, 
slashing operation, or dyeing/finishing operation for which you used the 
compliant material option. If there were no deviations from the 
applicable emission limit in Table 1 to this subpart, submit a statement 
that, as appropriate, the web coating/printing operations were in 
compliance with the emission limitations during the reporting period 
because you applied no coating or printing material for which the 
organic HAP content exceeded the applicable emission limit in Table 1 to 
this subpart, and you applied only thinning and cleaning materials that 
contained no organic HAP (as defined in Sec. 63.4371) in a web coating/
printing affected source; the slashing operations were in compliance 
with the emission limitations during the reporting period because you 
applied only slashing materials with no organic HAP (as defined in 
Sec. 63.4371) in a slashing affected source; and the dyeing/finishing 
operations were in compliance with the emission limitations during the 
reporting period because you applied no dyeing or finishing material for 
which the mass fraction of organic HAP exceeded the applicable emission 
limit in Table 1 to this subpart.
    (d) You must maintain records as specified in Secs. 63.4312 and 
63.4313.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4330  By what date must I conduct the initial compliance demonstration?

    You must complete the compliance demonstration for the initial 
compliance period according to the requirements of Sec. 63.4331. The 
initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4283 and ends on the last day of the 12th full 
month after the compliance date. The initial compliance demonstration 
includes the calculations according to Sec. 63.4331 and supporting 
documentation showing that for web coating/printing operations, the 
organic HAP emission rate for the initial compliance period was equal to 
or less than the applicable emission limit in Table 1 to this subpart 
and for dyeing/finishing operations, the mass fraction of organic HAP 
for the initial compliance period was less than or equal to the 
applicable emission limit in Table 1 to this subpart.



Sec. 63.4331  How do I demonstrate initial compliance with the emission limitations?

    (a) For web coating/printing operations, you may use the emission 
rate without add-on controls option for any individual web coating/
printing operation, for any group of web coating/printing operations in 
the affected source, or for all the web coating/printing operations as a 
group in the affected source. You must use either the compliant material 
option, the emission rate with add-on controls option, the organic HAP 
overall control efficiency option, or the oxidizer outlet organic HAP 
concentration option for any web coating/printing operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the emission rate without add-on controls 
option, the web coating/printing operation or group of web coating/
printing operations must meet the applicable emission limit in Table 1 
to this subpart but is not required to meet the operating limits or work 
practice standards in Secs. 63.4292 and 63.4293, respectively. You must 
meet all the requirements of paragraphs (a)(1) through (7) of this 
section to demonstrate initial compliance with the applicable emission 
limit in Table 1 to this subpart for the web coating/printing 
operation(s). When calculating the organic HAP emission rate according 
to this section, do not include any coating, printing, thinning, or 
cleaning materials applied on web coating/printing operations for which 
you use the compliant material option, the emission rate with add-on

[[Page 339]]

controls option, the organic HAP overall control efficiency option, or 
the oxidizer outlet organic HAP concentration option. Use the procedures 
in this section on each regulated material in the condition it is in 
when it is received from its manufacturer or supplier and prior to any 
alteration.
    (1) Determine the mass fraction of organic HAP for each material.

followed. For Method 625, make corrections to the compounds for which 
the analysis is being conducted based on the accuracy as recovery 
factors in Table 7 of the method.

[[Page 344]]

    (iii) Sampling plan. If you have been expressly referred to this 
paragraph by provisions of this subpart, you shall prepare a sampling 
plan. Wastewater samples shall be collected using sampling procedures 
which minimize loss of organic compounds during sample collection and 
analysis and maintain sample integrity. The sampling plan shall include 
procedures for determining recovery efficiency of the relevant organic 
HAP. An example of an example sampling plan would be one that

point of determination. You shall make corrections to the specific 
compound average concentration or total organic HAP average 
concentration when the concentration is determined downstream of the 
point of determination at a location where either wastewater streams 
from outside of the affected dyeing/finishing operation or group of 
dyeing/finishing operations have been mixed with the affected wastewater 
stream or one or more affected wastewater streams have been treated. You 
shall make the adjustments either to the individual data points or to 
the final average organic HAP concentration.

scenario, as defined in Sec. 63.4371, for which you have determined the 
organic HAP content of the wastewater stream, you shall determine the 
annual average mass flow rate, Fw, of the wastewater stream 
either at the point of determination or downstream of the point of 
determination with adjustment for flow rate changes made according to 
paragraph (c)(2)(ii) of this section. The annual average mass flow rate 
for the wastewater stream shall be representative of actual or 
anticipated operation of the dyeing/finishing operation(s) generating 
the wastewater over the compliance period. You must determine the annual 
average mass flow rate of each wastewater stream according to paragraphs

    (i) Procedures. The procedures specified in paragraphs (c)(2)(i)(A) 
through (C) of this section are considered acceptable procedures for 
determining the mass flow rate. They may be used in combination, and no 
one procedure shall take precedence over another.
    (A) Knowledge of the wastewater. You may use knowledge of the 
wastewater stream and/or the process to determine the annual average 
mass flow rate. You shall use the maximum expected annual average 
production capacity of the dyeing/finishing operation(s), knowledge of 
the process, and/or mass balance information to either estimate directly 
the average wastewater mass flow rate for the compliance period or 
estimate the total wastewater mass flow for the compliance period and 
then factor the total mass by the percentage of time in the compliance 
period the operating scenario is expected to represent. Where you use 
knowledge to determine the annual average mass flow rate, you shall 
provide sufficient

[[Page 345]]

information to document the mass flow rate.
    (B) Historical records. You may use historical records to determine 
the average annual mass flow rate. Derive the highest annual average 
mass flow rate of wastewater from historical records representing the 
most recent 5 years of operation, or if the dyeing/finishing 
operation(s) has(have) been in service for less than 5 years but at 
least 1 year, from historical records representing the total operating 
life of the process unit. Where historical records are used to determine 
the annual average mass flow rate, you shall provide sufficient 
information to document the mass flow rate.
    (C) Measurement of mass flow rate. If you elect to measure mass flow 
rate, you shall comply with the requirements of this paragraph. 
Measurements shall be made at the point of determination, or at a 
location downstream of the point of determination with adjustments for 
mass flow rate changes made according to paragraph (c)(2)(ii) of this 
section. Where measurement data are used to determine the annual average 
mass flow rate, you shall provide sufficient information to document the 
mass flow rate.
    (ii) Adjustment for flow rates determined downstream of the point of 
determination. You shall make corrections to the average annual mass 
flow rate of a wastewater stream when it is determined downstream of the 
point of determination at a location where either wastewater streams 
from outside of the affected dyeing/finishing operation or group of 
dyeing/finishing operations have been mixed with the affected wastewater 
stream or one or more wastewater streams have been treated. You shall 
make corrections for such changes in the annual average mass flow rate.
    (3) Wastewater treatment. You shall document that the wastewater is 
either discharged to a POTW or onsite secondary wastewater treatment.
    (4) Determine the mass of organic HAP in the affected wastewater. 
Determine the total mass of organic HAP, WW, contained in the wastewater 
streams characterized by the procedures in paragraphs (c)(1) and (2) of 
this section, using Equation 7 of this section:
[GRAPHIC] [TIFF OMITTED] TR29MY03.010

Where:

WW = The total mass of organic HAP contained in the wastewater streams 
characterized by the procedures in paragraphs (c)(1) and (2) of this 
section, kg/yr
Hw,k = Average organic HAP concentration of wastewater stream 
k, ppmw
Fw,k = Annual average mass flow rate of wastewater stream k, 
Mg/yr
o = Number of wastewater streams characterized by the procedures in 
paragraphs (c)(1) and (2) of this section.

    This is your allowance for organic HAP discharged to wastewater and 
not emitted to the atmosphere, WW in Equation 4.
    (5) Determine the fraction of organic HAP applied that is discharged 
to the wastewater. For the purpose of taking credit for the wastewater 
allowance in continuous compliance demonstrations, determine the 
fraction of organic HAP applied in affected dyeing/finishing processes 
that is discharged to the wastewater, i.e., divide WW by the mass of 
organic HAP in the dyeing and finishing materials applied during the 
compliance period, A, as calculated in Equation 4A of this section. The 
wastewater allowance for this fraction of organic HAP that is not 
emitted from the affected dyeing/finishing operation(s) may be taken for 
each compliance period that the operating scenario, as defined in 
Sec. 63.4371, does not change from conditions during the performance 
test in a way that could increase the fraction of organic HAP emitted 
(e.g., an increase in process temperature or decrease in process 
pressure or a change in the type or mass fraction of organic HAP 
entering the dyeing/finishing operation.) The allowance, WW, must be 
calculated by multiplying the fraction of organic HAP applied in 
affected processes that is discharged to the wastewater determined from 
the most recent performance test by the mass of organic HAP in the 
dyeing and finishing materials applied during the compliance period, A, 
as calculated in Equation 4A of this section.

your dyeing/finishing affected source that is discharged to the 
wastewater, to demonstrate compliance with the equivalent emission rate 
option of Sec. 63.4291(c)(4), then you must determine it according to 
paragraphs (d)(1) through (5) of this section. You must include in the 
determination only wastewater streams generated by dyeing/finishing 
operations in your affected source. You shall determine the mass of 
organic HAP from the average organic HAP concentration and mass flow 
rate of each wastewater stream generated by each dyeing/finishing 
operation (or group of dyeing/finishing operations discharging to a 
common wastewater stream) in your affected source. You shall consider 
the actual or anticipated production over the compliance period and 
include all wastewater streams generated by the affected dyeing/
finishing operation(s) during this period. A performance test of the 
organic HAP loading to the wastewater shall be conducted for each 
operating scenario, as defined in Sec. 63.4371, during the compliance 
period.
    (1) Procedure to determine average organic HAP concentration. You 
must determine the average organic HAP concentration of each wastewater 
stream according to paragraphs (c)(1)(i) through (vi) of this section.
    (2) Procedures to determine mass flow rate. For each operating 
scenario, as defined in Sec. 63.4371, for which you have determined the 
organic HAP content of the wastewater stream, you shall determine the 
annual average mass flow rate of the wastewater stream either at the 
point of determination, or downstream of the point of determination with 
adjustment for flow rate changes made according to paragraph (c)(2)(ii) 
of this section. The annual average mass flow rate for the wastewater 
stream shall be representative of actual or anticipated operation of the 
dyeing/finishing operation(s) generating the wastewater over the 
compliance period. You must determine the annual average mass flow rate 
of each wastewater stream according to paragraphs (c)(2)(i) and (ii) of 
this section.

either discharged to a POTW or onsite secondary wastewater treatment.
    (4) Determine the mass of organic HAP in the affected wastewater. 
Determine the total mass of organic HAP, WW, contained in the wastewater 
streams characterized by the procedures in paragraphs (d)(1) and (2) of 
this section, using Equation 7 of this section.
    (5) Determine the fraction of organic HAP applied that is discharged 
to the wastewater. Determine the fraction of organic HAP applied in your 
dyeing/finishing affected source that is discharged to the wastewater, 
i.e., divide WW by the mass of organic HAP in the dyeing and finishing 
materials applied during the compliance period, A, as calculated in 
Equation 4A of this section. One of the conditions that must be met to 
demonstrate compliance with the equivalent emission rate option is that 
the fraction of organic HAP applied in your dyeing/finishing affected 
source that is discharged to the wastewater must be at least 90 percent.

and must be reported as specified in Secs. 63.4310(c)(6) and 
63.4311(a)(6).

Sec. 63.4311, you must identify any web coating/printing operation or 
dyeing/finishing operation for which you used the emission rate

[[Page 347]]

without add-on controls option. If there were no deviations from the 
applicable emission limit in Table 1 to this subpart, you must submit a 
statement that, as appropriate, the web coating/printing operations or 
the dyeing/finishing operations were in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance period was less than or equal to the applicable 
emission limit in Table 1 to this subpart.
    (d) You must maintain records as specified in Secs. 63.4312 and 
63.4313.

                                 Option



Sec. 63.4340  By what date must I conduct performance tests and other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4283. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to 
Sec. 63.4341(e)(5) or (f)(5), you must conduct a performance test of 
each capture system and add-on control device according to the 
procedures in Secs. 63.4360, 63.4361, and 63.4362, and establish the

Sec. 63.4341  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any individual web coating/printing operation, for any group of web 
coating/printing operations in the affected source, or for all of the 
web coating/printing operations in the affected source. You may include 
both controlled and uncontrolled web coating/printing operations in a 
group for which you use this option. You must use either the compliant 
material option, the emission rate without add-on controls option, the 
organic HAP overall control efficiency option, or the oxidizer outlet 
organic HAP concentration option for any web coating/printing operation 
in the affected source for which you do not use the emission rate with 
add-on controls option. To demonstrate initial compliance, any web 
coating/printing operation for which you use the emission rate with add-
on controls option must meet the applicable emission limitations in 
Table 1 to this subpart, and in Secs. 63.4292 and 63.4293. You must meet 
all the requirements of paragraphs (a), (c), (d), and (e) of this 
section. When calculating the organic HAP emission rate according to 
this section, do not include any coating, printing, thinning, or 
cleaning materials applied on web coating/printing operations for which 
you use the compliant material option, the emission rate without add-on 
controls option, the organic HAP overall control efficiency option, or 
the oxidizer outlet organic HAP concentration option. You do not need to 
redetermine the mass of organic HAP in coating, printing, thinning, or 
cleaning materials that have been reclaimed onsite and reused in the web 
coating/printing operation(s) for which you use the emission rate with 
add-on control option.
    (b) You may use the emission rate with add-on controls option for 
any individual dyeing/finishing operation, for any group of dyeing/
finishing operations in the affected source, or for all of the dyeing/
finishing operations in the affected source. You may include both 
controlled and uncontrolled dyeing/finishing operations in a group for 
which you use this option. You must use either the compliant material 
option or the emission rate without add-on controls option for any 
dyeing/finishing operation in the affected source for which you do not 
use the emission rate with add-on controls option. You may not use the 
emission rate with add-on controls option for any dyeing/finishing 
operation in a dyeing/finishing affected source for which you

[[Page 349]]

use the equivalent emission rate option. To demonstrate initial 
compliance, any dyeing/finishing operation for which you use the 
emission rate with add-on controls option must meet the applicable 
emission limitations in Table 1 to this subpart, and in Secs. 63.4292 
and 63.4293. You must meet all the requirements of paragraphs (b), (c), 
(d), and (f) this section. When calculating the organic HAP emission 
rate according to this section, do not include any dyeing or finishing 
materials applied on dyeing/finishing operations for which you use the 
compliant material option or the emission rate without add-on controls 
option. You do not need to redetermine the mass of organic HAP in dyeing 
or finishing materials that have been reclaimed onsite and reused in the 
dyeing/finishing operation(s) for which you use the emission rate with 
add-on controls option.
    (c) Compliance with operating limits. Except as provided in 
Sec. 63.4340(a)(4), and except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to 
Sec. 63.4341(e)(5) or (f)(5), you must establish and demonstrate 
continuous compliance during the initial compliance period with the 
operating limits required by Sec. 63.4292, using the procedures 
specified in Secs. 63.4363 and 63.4364.
    (d) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4293 during the initial compliance period as 
specified in Sec. 63.4312.
    (e) Compliance with web coating/printing emission limits. You must 
follow the procedures in paragraphs (e)(1) through (8) of this section 
to demonstrate compliance with the applicable web coating/printing 
emission limit in Table 1 to this subpart.
    (1) Determine the mass fraction of organic HAP, the mass fraction of 
solids, and mass of materials. Follow the procedures specified in 
Sec. 63.4331(a)(1), (2), and (3) to determine the mass fraction of 
organic HAP for each coating, printing, thinning, and cleaning material 
applied during the compliance period; the mass fraction of solids for 
each coating and printing material applied during the compliance period; 
and mass of each coating, printing, thinning, and cleaning material 
applied during the compliance period.
    (2) Calculate the mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4331, calculate the mass of 
organic HAP emissions before add-on controls from all coating, printing, 
thinning, and cleaning materials applied during the compliance period 
minus the organic HAP in certain waste materials in the web coating/
printing operation or group of web coating/printing operations for which 
you use the emission rate with add-on controls.
    (3) Calculate the organic HAP emissions reductions for each 
controlled web coating/printing operation. Determine the mass of organic 
HAP emissions reduced for each controlled web coating/printing operation 
during the compliance period. The emissions reductions determination 
quantifies the total organic HAP emissions that pass through the 
emission capture system and are destroyed or removed by the add-on 
control device. Use the procedures in paragraph (e)(4) of this section 
to calculate the mass of organic HAP emissions reductions for each 
controlled web coating/printing operation using an emission capture 
system and add-on control device other than a solvent recovery system 
for which you conduct liquid-liquid material balances. For each 
controlled web coating/printing operation using a solvent recovery 
system for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (e)(5) of this section to calculate the organic 
HAP emissions reductions.
    (4) Calculate the organic HAP emission reduction for each controlled 
web coating/printing operation not using liquid-liquid material balance. 
For each controlled web coating/printing operation using an emission 
capture system and add-on control device other than a solvent recovery 
system for which you conduct liquid-liquid material balances, calculate 
the organic HAP emissions reductions using Equation 1 of this section. 
The equation applies the emission capture system efficiency and add-on 
control device efficiency to the mass of organic HAP contained in the 
coating,

[[Page 350]]

printing, thinning, and cleaning materials applied in the web coating/
printing operation served by the emission capture system and add-on 
control device during the compliance period. For any period of time a 
deviation specified in Sec. 63.4342(c) or (d) occurs in the controlled 
web coating/printing operation, including a deviation during startup, 
shutdown, or malfunction, then you must assume zero efficiency for the 
emission capture system and add-on control device. Equation 1 of this 
section treats the coating, printing, thinning, and cleaning materials 
applied during such a deviation as if they were used on an uncontrolled 
web coating/printing operation for the time period of the deviation.

must be less than or equal to the applicable emission limit in Table 1 
to this subpart.

[[Page 354]]

You must keep all records as required by Secs. 63.4312 and 63.4313. As 
part of the Notification of Compliance Status required by Sec. 63.4310, 
you must identify the web coating/printing operation(s) for which you 
used the emission rate with add-on controls option and submit a 
statement that the web coating/printing operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because the organic HAP emission rate was less than or equal to 
the applicable emission limit in Table 1 to this subpart, and that you 
achieved the operating limits required by Sec. 63.4292 and the work 
practice standards required by Sec. 63.4293.
    (f) Compliance with dyeing/finishing emission limits. You must 
follow the procedures in paragraphs (f)(1) through (8) of this section 
to demonstrate compliance with the applicable dyeing/finishing emission 
limit in Table 1 to this subpart.
    (1) Determine the mass fraction of organic HAP and mass of 
materials. Follow the procedures specified in Sec. 63.4331(b)(1) and (2) 
to determine the mass fraction of organic HAP for each dyeing and 
finishing material applied and mass of each dyeing and finishing 
material applied during the compliance period.
    (2) Calculate the mass of organic HAP emissions before add-on 
controls. Using Equation 4 of Sec. 63.4331, calculate the mass of 
organic HAP emissions before add-on controls from all dyeing and 
finishing materials applied during the compliance period minus the 
organic HAP in certain waste materials and wastewaters in the dyeing/
finishing operation or group of dyeing/finishing operations for which 
you use the emission rate with add-on controls option.
    (3) Calculate the organic HAP emissions reductions for each 
controlled dyeing/finishing operation. Determine the mass of organic HAP 
emissions reduced for each controlled dyeing/finishing operation during 
the compliance period. The emissions reductions determination quantifies 
the total organic HAP emissions that pass through the emission capture 
system and are destroyed or removed by the add-on control device. Use 
the procedures in paragraph (f)(4) of this section to calculate the mass 
of organic HAP emissions reductions for each controlled dyeing/finishing 
operation using an emission capture system and add-on control device 
other than a solvent recovery system for which you conduct liquid-liquid 
material balances. For each controlled dyeing/finishing operation using 
a solvent recovery system for which you conduct a liquid-liquid material 
balance, use the procedures in paragraph (f)(5) of this section to 
calculate the organic HAP emissions reductions.
    (4) Calculate the organic HAP emission reduction for each controlled 
dyeing/finishing operation not using liquid-liquid material balance. For 
each controlled dyeing/finishing operation using an emission capture 
system and add-on control device other than a solvent recovery system 
for which you conduct liquid-liquid material balances, calculate the 
organic HAP emissions reductions using Equation 5 of this section. The 
equation applies the emission capture system efficiency and add-on 
control device efficiency to the mass of organic HAP contained in the 
dyeing and finishing materials applied in the dyeing/finishing operation 
served by the emission capture system and add-on control device during 
the compliance period. For any period of time a deviation specified in 
Sec. 63.4342(c) or (d) occurs in the controlled dyeing/finishing 
operation, including a deviation during startup, shutdown, or 
malfunction, then you must assume zero efficiency for the emission 
capture system and add-on control device. Equation 5 of this section 
treats the dyeing and finishing materials applied during such a

    (8) Compliance demonstration. To demonstrate initial compliance with 
the emission limit, the organic HAP emission rate with add-on controls 
for the compliance period, calculated using Equation 8 of this section, 
must be less than or equal to the applicable emission limit in Table 1 
to this subpart. You must keep all records as required by Secs. 63.4312 
and 63.4313. As part of the Notification of Compliance Status required 
by Sec. 63.4310, you must identify the dyeing/finishing operation(s) for 
which you used the emission rate with add-on controls option and submit 
a statement that the dyeing/finishing operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because the organic HAP emission rate was less than or equal to 
the applicable emission limit in Table 1 to this subpart, and that you 
achieved the operating limits required by Sec. 63.4292 and the work 
practice standards required by Sec. 63.4293.



Sec. 63.4342  How do I demonstrate continuous compliance with the emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Table 1 to this subpart, the organic HAP emission rate 
for each compliance period, determined according to Sec. 63.4341(e) for 
web coating/printing operations and according to Sec. 63.4341(f) for 
dyeing/finishing operations, must be equal to or less than the 
applicable emission limit in Table 1 to this subpart. Each month 
following the initial compliance period described in Sec. 63.4340 is a 
compliance period consisting of that month and the preceding 11 months. 
You must perform the calculations in Sec. 63.4341 on a monthly basis.

[[Page 358]]

    (b) If the organic HAP emission rate with add-on controls for any 
compliance period exceeded the applicable emission limit in Table 1 to 
this subpart, this is a deviation from the emission limitation for that 
compliance period and must be reported as specified in 
Secs. 63.4310(c)(6) and 63.4311(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4292 that applies to you, as specified in 
Table 2 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 2 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Secs. 63.4310(c)(6) and 
63.4311(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 2 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4341 (e)(4) 
and (f)(4), you must treat the regulated materials applied during a 
deviation on a controlled coating/printing or dyeing/finishing operation 
as if they were applied on an uncontrolled coating/printing or dyeing/
finishing operation for the time period of the deviation, as indicated 
in Equation 1 of Sec. 63.4341 for a web coating/printing operation, and 
in Equation 5 of Sec. 63.4341 for a dyeing/finishing operation.
    (d) You must meet the requirements for bypass lines in 
Sec. 63.4364(b) for controlled coating/printing or dyeing/finishing 
operations for which you do not conduct liquid-liquid material balances. 
If any bypass line is opened and emissions are diverted to the 
atmosphere when the web coating/printing or dyeing/finishing operation 
is running, this is a deviation that must be reported as specified in 
Secs. 63.4310(c)(6) and 63.4311(a)(7). For the purposes of completing 
the compliance calculations specified in Sec. 63.4341(e)(4), you must 
treat the coating, printing, thinning, and cleaning materials applied 
during a deviation on a controlled web coating/printing operation as if 
they were used on an uncontrolled web coating/printing operation for the 
time period of the deviation, as indicated in Equation 1 of 
Sec. 63.4341. For the purposes of completing the compliance calculations 
specified in Sec. 63.4341(f)(4), you must treat the dyeing and finishing 
materials applied during a deviation on a controlled dyeing/finishing 
operation as if they were used on an uncontrolled dyeing/finishing 
operation for the time period of the deviation, as indicated in Equation 
5 of Sec. 63.4341.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4293. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4312(j)(8), this is a deviation from the 
work practice standards that must be reported as specified in 
Secs. 63.4310(c)(6) and 63.4311(a)(7).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4311, you must identify the coating/printing and dyeing/
finishing operation(s) for which you use the emission rate with add-on 
controls option. If there were no deviations from the applicable 
emission limit in Table 1 to this subpart, you must submit a statement 
that, as appropriate, the web coating/printing operations or the dyeing/
finishing operations were in compliance with the emission limitations 
during the reporting period because the organic HAP emission rate for 
each compliance period was less than or equal to the applicable emission 
limit in Table 1 to this subpart, and you achieved the operating limits 
required by Sec. 63.4292 and the work practice standards required by 
Sec. 63.4293 during each compliance period.
    (g) During periods of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
or dyeing/finishing operation that may affect emission capture or 
control device efficiency, you must operate in accordance with the 
startup, shutdown, and malfunction plan required by Sec. 63.4300(c).
    (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
or dyeing/finishing operation that may affect emission capture or 
control device efficiency are

[[Page 359]]

not violations if you demonstrate to the Administrator's satisfaction 
that you were operating in accordance with the startup, shutdown, and 
malfunction plan. 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).
    (i) [Reserved]
    (j) You must maintain records as specified in Secs. 63.4312 and 
63.4313.

emission capture system and add-on control device required by 
Sec. 63.4292 until after you have completed the performance tests 
specified in paragraph (a)(1) of this section. Instead, you must 
maintain a log detailing the operation and maintenance of the emission 
capture system, add-on control device, and continuous parameter monitors 
during the period between the compliance date and the performance test. 
You must begin complying with the operating limits for your affected 
source on the date you complete the performance tests specified in 
paragraph (a)(1) of this section. This requirement does not apply to 
solvent recovery systems for which you conduct liquid-liquid material 
balances according to the requirements of Sec. 63.4351(d)(5).
    (b) Existing sources. For an existing affected source, you must meet 
the requirements of paragraphs (b)(1) through (3) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS

[[Page 360]]

than the applicable compliance date specified in Sec. 63.4283. Except 
for solvent recovery systems for which you conduct liquid-liquid 
material balances according to Sec. 63.4351(d)(5), you must conduct a 
performance test of each capture system and add-on control device 
according to the procedures in Secs. 63.4360, 63.4361, and 63.4362, and 
establish the operating limits required by Sec. 63.4292, within 180 days

established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4364; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.4293.



Sec. 63.4351  How do I demonstrate initial compliance?

    (a) You may use the organic HAP overall control efficiency option or 
the oxidizer outlet organic HAP concentration option for any individual 
web coating/printing operation, for any group of web coating/printing 
operations in the affected source, or for all of the web coating/
printing operations in the affected source. You may include both 
controlled and uncontrolled web coating/printing operations in a group 
for which you use the organic HAP overall control efficiency option. You 
must use either the compliant material option, the emission rate without 
add-on controls option, or the emission rate with add-on controls option 
for any web coating/printing operation(s) in the affected source for 
which you do not use either the organic HAP overall control efficiency 
option or the oxidizer outlet organic HAP concentration option. To 
demonstrate initial compliance, any web coating/printing operation for 
which you use the organic HAP overall control efficiency option must 
meet the applicable organic HAP overall control efficiency limitations 
in Table 1 to this subpart according to the procedures in paragraph (d) 
of this section. Any web coating/printing operation for which you use 
the oxidizer outlet organic HAP concentration option must meet the 20 
ppmw on a dry basis limit and achieve 100 percent capture efficiencies 
according to the procedures in paragraph (e) of this section. To 
demonstrate initial compliance with either option, you also must meet 
the applicable operating limits in Sec. 63.4292 according to the 
procedures in paragraph (b) of this section and the work practice 
standards in Sec. 63.4293 according to the procedures in paragraph (c) 
of this section. When calculating the organic HAP overall control 
efficiency according to this section, do not include any coating, 
printing, thinning, or cleaning materials applied on web coating/
printing operations for which you use the compliant material option, the 
emission rate without add-on controls option, the emission rate with 
add-on controls option, or the oxidizer outlet organic HAP concentration

[[Page 361]]

option. You do not need to redetermine the mass of organic HAP in 
coating, printing, thinning, or cleaning materials that have been 
reclaimed onsite and reused in web coating/printing operation(s) for 
which you use the organic HAP overall control efficiency option.
    (b) Compliance with operating limits. Except as provided in 
Sec. 63.4350(a)(4), and except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to 
Sec. 63.4351(d)(5), you must establish and demonstrate continuous 
compliance during the initial compliance period with the operating 
limits required by Sec. 63.4292, using the procedures specified in 
Secs. 63.4363 and 63.4364.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4293 during the initial compliance period as 
specified in Sec. 63.4312.
    (d) Compliance with organic HAP overall control efficiency limits. 
You must follow the procedures in paragraphs (d)(1) through (7) of this 
section to demonstrate compliance with the applicable organic HAP 
overall control efficiency limit in Table 1 to this subpart.
    (1) Determine the mass fraction of organic HAP and mass of coating 
or printing materials. Follow the procedures specified in 
Sec. 63.4331(a)(1) and (3) to determine the mass fraction of organic HAP 
and mass of each coating, printing, thinning, and cleaning material 
applied during the compliance period.
    (2) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4331, calculate the total mass of 
organic HAP emissions before add-on controls from all coating, printing, 
thinning, and cleaning materials applied during the compliance period 
minus the organic HAP in certain waste materials in the web coating/
printing operation or group of web coating/printing operations for which 
you use the organic HAP overall control efficiency option.
    (3) Calculate the organic HAP emissions reductions for each 
controlled web coating/printing operation. Determine the mass of organic 
HAP emissions reduced for each controlled web coating/printing operation 
during the compliance period. The emissions reductions determination 
quantifies the total organic HAP emissions that pass through the 
emission capture system and are destroyed or removed by the add-on 
control device. Use the procedures in paragraph (d)(4) of this section 
to calculate the mass of organic HAP emissions reductions for each 
controlled web coating/printing operation using an emission capture 
system and add-on control device other than a solvent recovery system 
for which you conduct liquid-liquid material balances. For each 
controlled web coating/printing operation using a solvent recovery 
system for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (d)(5) of this section to calculate the organic 
HAP emissions reductions.
    (4) Calculate the organic HAP emissions reductions for controlled 
web coating/printing operations not using liquid-liquid material 
balance. For each controlled web coating/printing operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances, 
calculate the organic HAP emissions reductions using Equation 1 of 
Sec. 63.4341. The equation applies the emission capture system 
efficiency and add-on control device efficiency to the mass of organic 
HAP contained in the coating, printing, thinning, and cleaning materials 
applied in the web coating/printing operation served by the emission 
capture system and add-on control device during the compliance period. 
For any period of time a deviation specified in Sec. 63.4352(c) or (d) 
occurs in the controlled web coating/printing operation, including a 
deviation during startup, shutdown, or malfunction, then you must assume 
zero efficiency for the emission capture system and add-on control 
device. Equation 1 of Sec. 63.4341 treats the coating, printing, 
thinning, and cleaning materials applied during such a deviation as if 
they were applied on an uncontrolled web coating/printing operation for 
the time period of the deviation.
    (i) Calculate the total mass of organic HAP in the coating and 
printing material(s) applied in the controlled

[[Page 362]]

web coating/printing operation during the compliance period, kg, using 
Equation 1A of Sec. 63.4341.
    (ii) Calculate the total mass of organic HAP in the thinning and 
cleaning materials applied in the controlled web coating/printing 
operation(s) during the compliance period, kg, using Equation 1B of 
Sec. 63.4341.
    (iii) Calculate the mass of organic HAP in the coating, printing, 
thinning, and cleaning materials applied in the controlled web coating/
printing operation during deviations specified in Sec. 63.4352(c) and 
(d), using Equation 1C of Sec. 63.4341.
    (5) Calculate the organic HAP emissions reductions for controlled 
web coating/printing operations using liquid-liquid material balance. 
For each controlled web coating/printing operation using a solvent 
recovery system for which you conduct liquid-liquid material balances, 
calculate the organic HAP emissions reductions by applying the volatile 
organic matter collection and recovery efficiency to the mass of organic 
HAP contained in the coating, printing, thinning, and cleaning materials 
applied in the web coating/printing operation controlled by the solvent 
recovery system during the compliance period. Perform a liquid-liquid 
material balance for the compliance period as specified in paragraphs 
(d)(5)(i) through (vi) of this section.
    (i) For each solvent recovery system, install, calibrate, maintain, 
and operate according to the manufacturer's specifications, a device 
that indicates the cumulative amount of volatile organic matter 
recovered by the solvent recovery system for the compliance period. The 
device must be initially certified by the manufacturer to be accurate to 
within [plusmn]2.0 percent of the mass of volatile organic matter 
recovered.
    (ii) For each solvent recovery system, determine the mass of 
volatile organic matter recovered for the compliance period, kg, based 
on measurement with the device required in paragraph (d)(5)(i) of this

    (iii) Determine the mass fraction of volatile organic matter for 
each coating and printing material applied in the web coating/printing 
operation controlled by the solvent recovery system during the 
compliance period, kg volatile organic matter per kg coating and 
printing material. You may determine the volatile organic matter mass 
fraction using Method 24 of 40 CFR part 60, appendix A, or an EPA 
approved alternative method, or you may use information provided by the 
manufacturer or supplier of the coating or printing material. In the 
event of any inconsistency between information provided by the 
manufacturer or supplier and the results of Method 24 of 40 CFR part 60, 
appendix A, or an approved alternative method, the test method results 
will govern.
    (iv) Measure the mass of each coating, printing, thinning, and 
cleaning material applied in the web coating/printing operation 
controlled by the solvent recovery system during the compliance period, 
kg.
    (v) For the compliance period, calculate the solvent recovery 
system's volatile organic matter collection and recovery efficiency 
using Equation 2 of Sec. 63.4341.
    (vi) Calculate the mass of organic HAP emissions reductions for the 
web coating/printing operation controlled by the solvent recovery system 
during the compliance period, using Equation 3 of Sec. 63.4341.
    (6) Calculate the organic HAP overall control efficiency. Determine 
the organic HAP overall control efficiency, kg organic HAP emissions 
reductions per kg organic HAP emissions before add-on controls during 
the compliance period, using Equation 1 of this section.

the organic HAP overall control efficiency calculated using Equation 1 
of this section must be at least 98 percent for new or reconstructed 
affected sources and at least 97 percent for existing affected sources. 
You must keep all records as required by Secs. 63.4312 and 63.4313. As 
part of the Notification of Compliance Status required by Sec. 63.4310, 
you must identify the web coating/printing operation(s) for which you 
used the organic HAP overall control efficiency option and submit a 
statement that the web coating/printing operation(s) was (were) in 
compliance with the emission limitations during the initial compliance 
period because the organic HAP overall control efficiency was greater 
than or equal to the applicable organic HAP overall control efficiency 
in Table 1 to this subpart, and you achieved the operating limits 
required by Sec. 63.4292 and the work practice standards required by 
Sec. 63.4293.
    (e) Compliance with oxidizer outlet organic HAP concentration limit. 
You must follow the procedures in paragraphs (e)(1) through (3) of this 
section to demonstrate compliance with the oxidizer outlet organic HAP 
concentration limit of no greater than 20 ppmw on a dry basis.
    (1) Install and operate a PTE. Install and operate a PTE around each 
work station and associated drying or curing oven in the web coating/
printing operation. An enclosure that meets the requirements in 
Sec. 63.4361(a) is considered a PTE. Route all organic HAP emissions 
from each PTE to an oxidizer.
    (2) Determine oxidizer outlet organic HAP concentration. Determine 
oxidizer outlet organic HAP concentration through performance tests 
using the procedures in Sec. 63.4362(a) and (b).
    (3) Compliance demonstration. To demonstrate initial compliance with 
the oxidizer outlet organic HAP concentration limit in Table 1 to this 
subpart, the oxidizer outlet organic HAP concentration must be no 
greater than 20 ppmv on a dry basis and the efficiency of the capture 
system must be 100 percent. You must keep all records as required by 
Secs. 63.4312 and 63.4313. As part of the Notification of Compliance 
Status required by Sec. 63.4310, you must identify the web coating/
printing operation(s) for which you used the oxidizer outlet organic HAP 
concentration option and submit a statement that the web coating/
printing operation(s) was (were) in compliance with the emission 
limitations during the initial compliance period because the oxidizer 
outlet organic HAP concentration was no greater than 20 ppmv on a dry 
basis, the efficiency of the capture system was 100 percent, and you 
achieved the operating limits required by Sec. 63.4292 and the work 
practice standards required by Sec. 63.4293.



Sec. 63.4352  How do I demonstrate continuous compliance with the emission limitations?

    (a) You must meet all the requirements of this section to 
demonstrate continuous compliance with the organic HAP overall control 
efficiency. The organic HAP overall control efficiency for each 
compliance period, determined according to the procedures

[[Page 364]]

in Sec. 63.4351(d), must be equal to or greater than the applicable 
organic HAP overall control efficiency limit in Table 1 to this subpart. 
Each month following the initial compliance period described in 
Sec. 63.4350 is a compliance period. You must perform the calculations 
in Sec. 63.4351(d) on a monthly basis. You must meet the applicable 
requirements of paragraphs (c) through (j) of this section to 
demonstrate continuous compliance with the oxidizer outlet organic HAP 
concentration limit.
    (b) If the organic HAP overall control efficiency for any compliance 
period failed to meet the applicable organic HAP overall control 
efficiency in Table 1 to this subpart, this is a deviation from the 
emission limitation for that compliance period and must be reported as 
specified in Secs. 63.4310(c)(6) and 63.4311(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4292 that applies to you, as specified in 
Table 2 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 2 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Secs. 63.4310(c)(6) and 
63.4311(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 2 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4351(d)(4), 
you must treat the coating, printing, thinning, and cleaning materials 
applied during a deviation on a controlled web coating/printing 
operation as if they were applied on an uncontrolled web coating/
printing operation for the time period of the deviation as indicated in 
Equation 1 of Sec. 63.4341.
    (d) You must meet the requirements for bypass lines in 
Sec. 63.4364(b) for controlled web coating/printing operations for which 
you do not conduct liquid-liquid material balances. If any bypass line 
is opened and emissions are diverted to the atmosphere when the web 
coating/printing operation is running, this is a deviation that must be 
reported as specified in Secs. 63.4310(c)(6) and 63.4311(a)(7). For the 
purposes of completing the compliance calculations specified in 
Sec. 63.4351(d)(4), you must treat the coating, printing, thinning, and 
cleaning materials applied during a deviation on a controlled web 
coating/printing operation as if they were applied on an uncontrolled 
web coating/printing operation for the time period of the deviation as 
indicated in Equation 1 of Sec. 63.4341.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4293. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4312(j)(8), this is a deviation from the 
work practice standards that must be reported as specified in 
Secs. 63.4310(c)(6) and 63.4311(a)(7).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4311, you must identify the web coating/printing operation(s) 
for which you use the organic HAP overall control efficiency option or 
the oxidizer outlet organic HAP concentration option. If there were no 
deviations from the organic HAP overall control efficiency limitations, 
submit a statement that you were in compliance with the emission 
limitations during the reporting period because the organic HAP overall 
control efficiency for each compliance period was greater than or equal 
to the applicable organic HAP overall control efficiency in Table 1 to 
this subpart, and you achieved the operating limits required by 
Sec. 63.4292 and the work practice standards required by Sec. 63.4293 
during each compliance period. If there were no deviations from the 
oxidizer outlet organic HAP concentration limit, submit a statement that 
you were in compliance with the oxidizer outlet organic HAP 
concentration limit, the efficiency of the capture system is 100 
percent, and you achieved the operating limits required by Sec. 63.4292 
and the work practice standards required by Sec. 63.4293 during each 
compliance period.
    (g) During periods of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
operation that may affect emission capture or control device efficiency, 
you must operate in

[[Page 365]]

accordance with the startup, shutdown, and malfunction plan required by 
Sec. 63.4300(c).
    (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or web coating/printing 
operation that may affect emission capture or control device efficiency 
are not violations if you demonstrate to the Administrator's 
satisfaction that you were operating in accordance with the startup, 
shutdown, and malfunction plan. 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).
    (i) [Reserved]
    (j) You must maintain records as specified in Secs. 63.4312 and 
63.4313.

             Performance Testing and Monitoring Requirements



Sec. 63.4360  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Secs. 63.4340 
or 63.4350 according to the requirements in Sec. 63.7(e)(1) and under 
the conditions in this section, unless you obtain a waiver of the 
performance test according to the provisions in Sec. 63.7(h).
    (1) Representative web coating/printing or dyeing/finishing 
operation operating conditions. You must conduct the performance test 
under representative operating conditions for the web coating/printing 
or dyeing/finishing operation. Operations during periods of startup, 
shutdown, or malfunction and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4361. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4362.



Sec. 63.4361  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Secs. 63.4340 or 63.4350.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met.
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All regulated materials applied in the web coating/printing or 
dyeing/finishing operation are applied within the capture system; 
regulated material solvent flash-off, curing, and drying occurs within 
the capture system; and the removal or evaporation of cleaning materials 
from the web coating/printing operation surfaces they are applied to 
occurs within the capture system. For example, this criterion is not met 
if the web enters the open shop environment when moving between the 
application station and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at

[[Page 366]]

least 3 hours duration or the length of a production run, up to 8 hours.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in regulated materials applied in the 
web coating/printing or dyeing/finishing operation to the mass of TVH 
emissions not captured by the emission capture system. Use a temporary 
total enclosure or a building enclosure and the procedures in paragraphs 
(c)(1) through (6) of this section to measure emission capture system 
efficiency using the liquid-to-uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the web coating/printing or dyeing/finishing operation where regulated 
materials are applied, and all areas where emissions from these applied 
regulated materials subsequently occur, such as flash-off, curing, and 
drying areas. The areas of the web coating/printing or dyeing/finishing 
operation where capture devices collect emissions for routing to an add-
on control device, such as the entrance and exit areas of an oven or 
tenter frame, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each regulated 
material used in the web coating/printing or dyeing/finishing operation 
during each capture efficiency test run. To make the determination, 
substitute TVH for each occurrence of the term volatile organic 
compounds (VOC) in the methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the regulated materials applied in the web 
coating/printing or dyeing/finishing operation during each capture 
efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR29MY03.028

Where:

TVHapplied = Mass of liquid TVH in regulated materials 
applied in the web coating/printing or dyeing/finishing operation during 
the capture efficiency test run, kg.
TVHi = Mass fraction of TVH in regulated material, i, that is 
applied in the web coating/printing or dyeing/finishing operation during 
the capture efficiency test run, kg TVH per kg material.
Mi = Total mass of regulated material, i, applied in the web 
coating/printing or dyeing/finishing operation during the capture 
efficiency test run, kg.
n = Number of different regulated materials applied in the web coating/
printing or dyeing/finishing operation during the capture efficiency 
test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, kg, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound-emitting 
operations inside the building enclosure, other than the web coating/
printing or dyeing/finishing operation for which capture efficiency is 
being determined, must be shut down, but all fans and blowers must be 
operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:

[[Page 367]]

[GRAPHIC] [TIFF OMITTED] TR29MY03.029

Where:

CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHapplied = Total mass of TVH liquid input applied in the 
web coating/printing or dyeing/finishing operation during the capture 
efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the web coating/printing or dyeing/finishing operation where regulated 
materials are applied, and all areas where emissions from these applied 
regulated materials subsequently occur, such as flash-off, curing, and 
drying areas. The areas of the web coating/printing or dyeing/finishing 
operation where capture devices collect emissions generated by the web 
coating/printing or dyeing/finishing operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
tenter frame, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound-emitting 
operations inside the building enclosure, other than the web coating/
printing or dyeing/finishing operation for which capture efficiency is 
being determined, must be shut down, but all fans and blowers must be 
operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:

[[Page 368]]

[GRAPHIC] [TIFF OMITTED] TR29MY03.030

Where:

CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4362  How do I determine the add-on control device emission destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Secs. 63.4340 and 
63.4350. You must conduct three test runs as specified in 
Sec. 63.7(e)(3) and each test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods as 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME, PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see 
Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure the volatile organic matter concentration as carbon at 
the inlet and outlet of the add-on control device simultaneously, using 
Method 25 or 25A of appendix A to 40 CFR part 60. If you are 
demonstrating compliance with the oxidizer outlet organic HAP 
concentration limit, only the outlet volatile organic matter 
concentration must be determined. The outlet volatile organic matter 
concentration is determined as the average of the three test runs.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet. Method 25A must be used to 
demonstrate compliance with the oxidizer outlet organic HAP 
concentration limit.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission

[[Page 369]]

stream, then you must measure emissions at the outlet to the atmosphere 
of each device. For example, if one add-on control device is a 
concentrator with an outlet to the atmosphere for the high-volume, 
dilute stream that has been treated by the concentrator, and a second 
add-on control device is an oxidizer with an outlet to the atmosphere 
for the low-volume, concentrated stream that is treated with the 
oxidizer, you must measure emissions at the outlet of the oxidizer and 
the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions:
[GRAPHIC] [TIFF OMITTED] TR29MY03.031

Where:

Mf = Total gaseous organic emissions mass flow rate, kg/hour 
(h).
Cc = Concentration of organic compounds as carbon in the vent 
gas, as determined by Method 25 or Method 25A, ppmv, dry basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, 
dry standard cubic meters/hour (dscm/h).
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
(mole/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury (mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency using Equation 2 of this 
section.
[GRAPHIC] [TIFF OMITTED] TR29MY03.032

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
inlet(s) to the add-on control device, using Equation 1 of this section, 
kg/h.
Mfo = Total gaseous organic emissions mass flow rate at the 
outlet(s) of the add-on control device, using Equation 1 of this 
section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4363  How do I establish the add-on control device operating limits during the performance test?

    During the performance test required by Secs. 63.4340 or 63.4350 and 
described in Secs. 63.4360, 63.4361, and 63.4362, you must establish the 
operating limits required by Sec. 63.4292 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4292.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at least once every 15 minutes during each of the three test 
runs. You must monitor the temperature in the firebox of the thermal 
oxidizer or immediately downstream of the firebox before any substantial 
heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature maintained during the performance 
test.

[[Page 370]]

This average temperature is the minimum operating limit for your thermal 
oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature at the inlet to the catalyst bed and the temperature 
difference across the catalyst bed at least once every 15 minutes during 
each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature at the inlet to the catalyst bed and 
the average temperature difference across the catalyst bed maintained 
during the performance test. These are the minimum operating limits for 
your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4362.



Sec. 63.4364  What are the requirements for CPMS installation, operation, and maintenance?

    (a) General. If you are using a control device to comply with the 
emission standards in Sec. 63.4290, you must install, operate, and 
maintain each CPMS specified in paragraphs (c) and (d) and (e) of this 
section according to the requirements in paragraphs (a)(1) through (8) 
of this section. You must install, operate, and maintain each CPMS 
specified in paragraph (b) of this section according to paragraphs 
(a)(5) through (7) of this section.
    (1) Each CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation to have a valid hour 
of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the hourly average of all recorded readings 
according to paragraphs (a)(3)(i) and (ii) of this section.
    (i) To calculate a valid hourly value, you must have at least three 
of four equally spaced data values from that hour from a continuous 
monitoring system (CMS) that is not out-of-control.
    (ii) Provided all of the readings recorded in accordance with 
paragraph (a)(3) of this section clearly demonstrate continuous 
compliance with the standard that applies to you, then you are not 
required to determine the hourly average of all recorded readings.
    (4) You must determine the rolling 3-hour average of all recorded 
readings for each operating period. To calculate the average for each 3-
hour averaging

[[Page 371]]

period, you must have at least two of three of the hourly averages for 
that period using only average values that are based on valid data 
(i.e., not from out-of-control periods).
    (5) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (6) At all times, you must maintain the monitoring system in proper 
working order including, but not limited to, maintaining necessary parts 
for routine repairs of the monitoring equipment.
    (7) Except for monitoring malfunctions, associated repairs, or 
required quality assurance or control activities (including calibration 
checks or required zero and span adjustments), you must conduct all 
monitoring at all times that the unit is operating. Data recorded during 
monitoring malfunctions, associated repairs, out-of-control periods, or 
required quality assurance or control activities shall not be used for 
purposes of calculating the emissions concentrations and percent 
reductions specified in Table 1 to this subpart. You must use all the 
valid data collected during all other periods in assessing compliance of 
the control device and associated control system. A monitoring 
malfunction is any sudden, infrequent, not reasonably preventable 
failure of the monitoring system to provide valid data. Monitoring 
failures that are caused in part by poor maintenance or careless 
operation are not malfunctions.
    (8) Any averaging period for which you do not have valid monitoring 
data and such data are required constitutes a deviation, and you must 
notify the Administrator in accordance with Sec. 63.4311(a).
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (a)(5) through (6) and (b)(1) and (2) of this section for 
each emission capture system that contains bypass lines that could 
divert emissions away from the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve is in the closed (non-diverting) position through monitoring 
of valve position at least once every 15 minutes. You must inspect the 
monitoring system at least once every month to verify that the monitor 
will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the web coating/printing or dyeing/finishing operation is stopped 
when flow is diverted by the bypass line away from the add-on control 
device to the atmosphere when the web coating/printing or dyeing/
finishing operation is running. You must inspect the automatic shutdown 
system at least once every month to verify that it will detect 
diversions of flow and shutdown the web coating/printing or dyeing/
finishing operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length

[[Page 372]]

of time it remained open in the semiannual compliance reports required 
in Sec. 63.4311.
    (c) Oxidizers. If you are using an oxidizer to comply with the 
emission standards, you must comply with paragraphs (c)(i) through (iii) 
of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to the manufacturer's specifications. The 
calibration of the chart recorder, data logger, or temperature indicator 
must be verified every 3 months or the chart recorder, data logger, or 
temperature indicator must be replaced.
    (ii) For an oxidizer other than a catalytic oxidizer, install, 
calibrate, operate, and maintain a temperature monitoring device 
equipped with a continuous recorder. The device must have an accuracy of 
[plusmn]1 percent of the temperature being monitored in degrees Celsius, 
or [plusmn]1 [deg]Celsius, whichever is greater. The thermocouple or 
temperature sensor must be installed in the combustion chamber at a 
location in the combustion zone.
    (iii) For a catalytic oxidizer, install, calibrate, operate, and 
maintain a temperature monitoring device equipped with a continuous 
recorder. The device must be capable of monitoring temperature with an 
accuracy of [plusmn]1 percent of the temperature being monitored in 
degrees Celsius or [plusmn] 1 degree Celsius, whichever is greater. The 
thermocouple or temperature sensor must be installed in the vent stream 
at the nearest feasible point to the inlet and outlet of the catalyst 
bed. Calculate the temperature rise across the catalyst.
    (d) Other types of control devices. If you use a control device 
other than an oxidizer or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of an alternative monitoring method under 
Sec. 63.8(f).
    (e) Capture system monitoring. If you are complying with the 
emission standards in Sec. 63.4290 through the use of a capture system 
and control device, you must develop a site-specific monitoring plan 
containing the information specified in paragraphs (e)(1) and (2) of 
this section for these capture systems. You must monitor the capture 
system in accordance with paragraph (e)(3) of this section. You must 
make the monitoring plan available for inspection by the permitting 
authority upon request.
    (1) The monitoring plan must:
    (i) Identify the operating parameter to be monitored to ensure that 
the capture efficiency determined during the initial compliance test is 
maintained; and
    (ii) Explain why this parameter is appropriate for demonstrating 
ongoing compliance; and
    (iii) Identify the specific monitoring procedures.
    (2) The monitoring plan must specify the operating parameter value 
or range of values that demonstrate compliance with the emission 
standards in Sec. 63.4290. The specified operating parameter value or 
range of values must represent the conditions present when the capture 
system is being properly operated and maintained.
    (3) You must conduct all capture system monitoring in accordance 
with the plan.
    (4) Any deviation from the operating parameter value or range of 
values which are monitored according to the plan will be considered a 
deviation from the operating limit.
    (5) You must review and update the capture system monitoring plan at 
least annually.

Sec. 63.4371  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Add-on control means an air pollution control device, such as a 
thermal oxidizer or carbon adsorber, that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    As-applied means the condition of a coating at the time of 
application to a substrate, including any added solvent.
    As purchased means the condition of a coating, printing, slashing, 
dyeing, or finishing material as delivered to the affected source, 
before alteration.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency means the portion (expressed as a percentage) of 
the pollutants from an emission source that is delivered to an add-on 
control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a web coating/printing or dyeing/finishing 
operation in the use of regulated materials, both at the point of 
application and at subsequent points where emissions from the regulated 
materials occur, such as flashoff, drying, or curing. As used in this 
subpart, multiple capture devices that collect emissions generated by a 
web coating/printing or dyeing/finishing operation are considered a 
single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, or oil, from a textile before a 
web coating/printing operation (surface preparation) or from equipment 
associated with the web coating/ printing operation, such as tanks, 
rollers, rotary screens, and knife or wiper blades. Thus, it includes 
any cleaning material used in the web coating and printing subcategory 
for surface preparation of substrates or process operation equipment 
cleaning or both with the exception of cleaning material applied to the 
substrate using handheld, non-refillable aerosol containers.
    Coating means the application of a semi-liquid coating material to 
one or both sides of a textile web substrate. Once the coating material 
is dried (and cured, if necessary), it bonds with the textile to form a 
continuous solid film for decorative, protective, or functional 
purposes. Coating does not include finishing where the fiber is 
impregnated with a chemical or resin to impart certain properties, but a 
solid film is not formed.
    Coating material means an elastomer, polymer, or prepolymer material 
applied as a thin layer to a textile web. Such materials include, but 
are not limited to, coatings, sealants, inks, and adhesives. Decorative, 
protective, or functional materials that consist only of acids, bases, 
or any combination of these substances are not considered coating 
material for the purposes of this subpart. Thinning materials also are 
not included in this definition of coating materials, but are accounted 
for separately.
    Coating operation means equipment used to apply cleaning materials 
to a web substrate to prepare it for coating material application 
(surface preparation), to apply coating material to a web substrate 
(coating application) and to dry or cure the coating material after 
application by exposure to heat or radiation (coating drying or curing), 
or to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any

[[Page 374]]

combination of these types of equipment, but always includes at least 
the point at which a coating or cleaning material is applied and all 
subsequent points in the affected source where organic HAP emissions 
from that coating or cleaning material occur. There may be multiple 
coating operations in an affected source. Coating material application 
with handheld, non-refillable aerosol containers, touch-up markers, or 
marking pens is not a coating operation for the purposes of this 
subpart. Polyurethane foam carpet backing operations are not coating 
operations for the purposes of this subpart.
    Container means any portable device in which a material is stored, 
conveyed, treated, disposed of, or otherwise handled.
    Continuous parameter monitoring system means the total equipment 
that may be required to meet the data acquisition and availability 
requirements of this subpart, used to sample, condition (if applicable), 
analyze, and provide a record of coating or printing operation, or 
capture system, or add-on control device parameters.
    Controlled web coating/printing or dyeing/finishing operation means 
a web coating/printing or dyeing/finishing operation from which some or 
all of the organic HAP emissions are routed through an emission capture 
system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Dyeing means the process of applying color to the whole body of a 
textile substrate with either natural or synthetic dyes. Dyes are 
applied to yarn, fiber, cord, or fabric in aqueous solutions and dried 
before or after finishing, depending on the process. Continuous dyeing 
processes include, but are not limited to thermosol, pad/steam, pad/dry, 
and rope range dyeing. Batch dyeing processes include, but are not 
limited to, jet, beck, stock, yarn, kier, beam, pad, package and skein 
dyeing.
    Dyeing materials means the purchased dyes and dyeing auxiliaries 
that are used in the dyeing process. The dyes are the substances that 
add color to textiles through incorporation into the fiber by chemical 
reaction, absorption or dispersion. Dyeing auxiliaries are various 
substances that can be added to the dyebath to aid dyeing. Dyeing 
auxiliaries may be necessary to transfer the dye from the dyebath to the 
fiber or they may provide improvements in the dyeing process or 
characteristics of the dyed fiber.
    Dyeing operation means the collection of equipment used to dye a 
textile substrate and includes equipment used for dye application, dye 
fixation, and textile substrate rinsing and drying. A single dyeing 
operation may include any combination of these types of equipment, but 
always includes at least the point at which a dyeing material is applied 
and all subsequent points in the affected source where organic HAP 
emissions from that dyeing material occur. There may be multiple dyeing 
operations in an affected source. Dyeing material application with 
handheld, non-refillable aerosol containers, touch-up markers, brushes, 
or marking pens is not a dyeing operation for the purposes of this 
subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.
    Fabric means any woven, knitted, plaited, braided, felted, or non-
woven material made of filaments, fibers, or yarns including thread. 
This term includes material made of fiberglass, natural fibers, 
synthetic fibers, or composite.

[[Page 375]]

    Finishing means the chemical treatment of a textile (e.g., with 
resins, softeners, stain resist or soil release agents, water 
repellants, flame retardants, antistatic agents, or hand builders) that 
improves the appearance and/or usefulness of the textile substrate.

auxiliaries added to the finish to improve the finishing process or the 
characteristics of the finished textile) that are applied individually 
or as mixtures to textile substrates to impart desired properties.
    Finishing operations means the collection of equipment used to 
finish a textile substrate including chemical finish applicator(s), 
flashoff area(s) and drying or curing oven(s).
    Laminated fabric means fabric composed of a high-strength 
reinforcing base fabric between two plies of flexible thermoplastic 
film. Two or more fabrics or textiles or a fabric and a paper substrate 
may be bonded with an adhesive to form a laminate. The bonding of a 
fabric substrate to paper is not subject to the requirements of this 
subpart.
    Manufacturer's formulation data means data on a material (such as a 
coating, printing, slashing, dyeing and finishing) that are supplied by 
the material manufacturer based on knowledge of the ingredients used to 
manufacture that material, rather than based on testing of the material.

information on density, organic HAP content, and coating, printing, 
dyeing, slashing, finishing, thinning, or cleaning material content.
    Mass fraction of organic HAP means the ratio of the mass of organic 
HAP to the mass of a material in which it is contained; kg of organic 
HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    No organic HAP means no organic HAP is present at 0.1 percent by 
mass or more for OSHA-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
The organic HAP content of a regulated material is determined according 
to Sec. 63.4321(e)(1).
    Operating scenario means for a dyeing/finishing process operation or 
group of process operations, the combination of operating conditions 
(including but not limited to, type of substrate, type and mass fraction 
of organic HAP in dyeing/finishing materials applied, and the process 
operation temperature and pressure) affecting the fraction of organic 
HAP applied in dyeing and finishing operations discharged to wastewater. 
For example, a dyeing process operation run at atmospheric pressure 
would be a different operating scenario from the same dyeing process 
operation run under pressure.
    Organic HAP content means the mass of organic HAP per mass of solids 
for a coating or printing material calculated using Equation 1 of 
Sec. 63.4321. The organic HAP content is determined for the coating or 
printing material as purchased.
    Organic HAP overall control efficiency means the total efficiency of 
a control system, determined either by:
    (1) The product of the capture efficiency as determined in 
accordance with the requirements of Sec. 63.4361 and the control device 
organic emissions destruction or removal efficiency determined in 
accordance with the requirements of Sec. 63.4362; or
    (2) A liquid-liquid material balance in accordance with the

enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.
    Point of determination means each point where process wastewater 
exits the dyeing/finishing process unit.
    Printing means the application of color and patterns to textiles, 
usually in the form of a paste, using a variety of techniques including, 
but not limited to roller, rotary screen, and ink jet printing. After 
application of the printing material, the textile usually is treated 
with steam, heat, or chemicals to fix the color.

[[Page 376]]

gums or thickeners, dyes and appropriate chemicals such as defoamers and 
resins that are mixed to produce the print pastes applied to textile 
substrates as patterns and colors.
    Printing operation means equipment used to apply cleaning materials 
to a web substrate to prepare it for printing material application 
(surface preparation), to apply printing material to one or both sides 
of a web substrate (printing application) and to dry or cure the 
printing material after application by exposure to heat or radiation 
(printing material drying or curing), or to clean printing operation 
equipment (equipment cleaning). A single printing operation may include 
any combination of these types of equipment, but always includes at 
least the point at which a printing or cleaning material is applied and

                          Emission Limitations



Sec. 63.4690  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must limit 
organic HAP emissions to the atmosphere to no more than the applicable 
emission limit(s) in Table 1 to this subpart, determined according to 
the requirements in Secs. 63.4741, 63.4751, or 63.4761.
    (b) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than the applicable emission 
limit(s) in Table 2 to this subpart, determined according to the 
requirements in Sec. 63.4741, Sec. 63.4751, or Sec. 63.4761.
    (c) If the affected source applies coatings to products that are in 
different subcategories as described in Sec. 63.4681(a), then you must 
demonstrate initial and continuous compliance by selecting one of the 
approaches described in paragraphs (c)(1) and (2) of this section.
    (1) Conduct separate compliance demonstrations for each applicable 
subcategory emission limit and reflect these separate determinations in 
notifications, reports, and records required by Secs. 63.4710, 63.4720, 
and 63.4730, respectively.
    (2) Demonstrate compliance with the most stringent of the applicable 
subcategory emission limits.



Sec. 63.4691  What are my options for meeting the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable emission limit in 
Sec. 63.4690. To make this determination, you must use at least one of 
the three compliance options listed in paragraphs (a) through (c) of 
this section. You may apply any of the compliance options to an 
individual coating operation or to multiple coating operations as a 
group or to the entire affected source. You may use different compliance 
options for different coating operations or at different times on the 
same coating operation. However, you may not use different compliance 
options at the same time on the same coating operation. If you switch 
between compliance options for any coating operation or group of coating 
operations, you must document this switch as required by 
Sec. 63.4730(c), and you must report it in the next semiannual 
compliance report required in Sec. 63.4720.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation(s) is less than or 
equal to the applicable emission limit(s) in Sec. 63.4690, and that each 
thinner and each cleaning material used contains no organic HAP. You 
must meet all the requirements of Secs. 63.4740, 63.4741, and 63.4742 to 
demonstrate compliance with the emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation(s), the organic HAP emission rate for the coating 
operation(s) is less than or equal to the applicable emission limit(s) 
in Sec. 63.4690, calculated as a rolling 12-month emission rate and 
determined on a monthly basis. You must meet all the requirements of 
Secs. 63.4750, 63.4751, and 63.4752 to demonstrate compliance with the 
emission limit using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation(s) and the emission reductions achieved by emission 
capture systems and add-on controls, the organic HAP emission rate for 
the coating operation(s) is less than or equal to the applicable 
emission limit(s) in Sec. 63.4690, calculated as a rolling 12-month 
emission rate and determined on a monthly basis. If you use this 
compliance option, you must also demonstrate that all emission capture 
systems and add-on control devices for the coating operation(s) meet the 
operating limits required in Sec. 63.4692, except for solvent recovery 
systems for which you conduct liquid-liquid material balances according 
to Sec. 63.4761(j), and that you meet the work practice standards 
required in Sec. 63.4693. You must meet all the requirements of

[[Page 388]]

Sec. Sec. 63.4760 through 63.4768 to demonstrate compliance with the 
emission limits, operating limits, and work practice standards using 
this option.



Sec. 63.4692  What operating limits must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any operating limits.
    (b) For any controlled coating operation(s) on which you use the 
emission rate with add-on controls option, except those for which you 
use a solvent recovery system and conduct a liquid-liquid material 
balance according to Sec. 63.4761(j), you must meet the operating limits 
specified in Table 3 to this subpart. These operating limits apply to 
the emission capture and control systems on the coating operation(s) for 
which you use this option, and you must establish the operating limits 
during the performance test according to the requirements in 
Sec. 63.4767. You must meet the operating limits at all times after you 
establish them.
    (c) If you use an add-on control device other than those listed in 
Table 3 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 63.8(f).



Sec. 63.4693  What work practice standards must I meet?

    (a) For any coating operation(s) on which you use the compliant 
material option or the emission rate without add-on controls option, you 
are not required to meet any work practice standards.
    (b) If you use the emission rate with add-on controls option, you 
must develop and implement a work practice plan to minimize organic HAP 
emissions from the storage, mixing, and conveying of coatings, thinners, 
and cleaning materials used in, and waste materials generated by, the 
coating operation(s); or you must meet an alternative standard as 
provided in paragraph (d) of this section. The plan must specify 
practices and procedures to ensure that, at a minimum, the elements 
specified in paragraphs (b)(1) through (5) of this section are 
implemented. You must make the plan available upon request for 
inspection by the Administrator.
    (1) All organic-HAP coatings, thinners, cleaning materials, and 
waste materials must be stored in closed containers.
    (2) Spills of organic-HAP coatings, thinners, cleaning materials, 
and waste materials must be minimized.
    (3) Organic-HAP coatings, thinners, cleaning materials, and waste 
materials must be conveyed from one location to another in closed 
containers or pipes.
    (4) Mixing vessels that contain organic-HAP coatings and other 
materials must be closed except when adding to, removing, or mixing the 
contents.
    (5) Emissions of organic-HAP must be minimized during cleaning of 
storage, mixing, and conveying equipment.
    (c) If your affected source has an existing documented plan that 
incorporates steps taken to minimize emissions from the sources 
specified in paragraphs (b)(1) through (5) of this section, then your 
existing plan can be used to meet the requirement for a work practice 
plan as specified in paragraph (b) of this section.
    (d) As provided in Sec. 63.6(g), we, the U.S. Environmental 
Protection Agency (U.S. EPA), may choose to grant you permission to use 
an alternative to the work practice standards in this section.

specified in paragraphs (a)(1)(i) through (iv) of this section. Note 
that the information reported for each of the months in the reporting 
period will be based on the last 12 months of data prior to the date of 
each monthly calculation.
    (i) The first semiannual compliance report must cover the first 
semiannual reporting period which begins the day after the end of the 
initial compliance period described in Sec. 63.4740, Sec. 63.4750, or 
Sec. 63.4760 that applies to your affected source and ends on June 30 or 
December 31, whichever occurs first following the end of the initial 
compliance period.
    (ii) Each subsequent semiannual compliance report must cover the 
subsequent semiannual reporting period from January 1 through June 30 or 
the semiannual reporting period from July 1 through December 31.

first date following the end of the semiannual reporting period.
    (iv) For each affected source that is subject to permitting 
regulations pursuant to 40 CFR part 70 or 40 CFR part 71, and if the 
permitting authority has established dates for submitting semiannual 
reports pursuant to 40 CFR 70.6(a)(3)(iii)(A) or 40 CFR 
71.6(a)(3)(iii)(A), you may submit the first and subsequent compliance 
reports according to the dates the permitting authority has established 
instead of according to the date specified in paragraph (a)(1)(iii) of 
this section.
    (2) Inclusion with title V report. Each affected source that has 
obtained a title V operating permit pursuant to 40 CFR part 70 or 40 CFR 
part 71 must report all deviations as defined in this subpart in the 
semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) or 40 
CFR 71.6(a)(3)(iii)(A). If an affected source submits a semiannual 
compliance report pursuant to this section along with, or as part of, 
the semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) 
or 40 CFR 71.6(a)(3)(iii)(A), and the semiannual compliance report 
includes all required information concerning deviations from any 
emission limitation in this subpart, its submission shall be deemed to 
satisfy any obligation to report the same deviations in the semiannual 
monitoring report. However, submission of a semiannual compliance report 
shall not otherwise affect any obligation the affected source may have 
to report deviations from permit requirements to the permitting 
authority.
    (3) General requirements. The semiannual compliance report must 
contain the information specified in paragraphs (a)(3)(i) through (v) of

        Compliance Requirements for the Compliant Material Option



Sec. 63.4740  By what date must I conduct the initial compliance demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 63.4741. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4683 and ends on the last day of the 12th month 
following the compliance date. If the compliance date occurs on any day 
other than the first day of a month, then the initial compliance period 
extends through the end of that month plus the next 12 months. The 
initial compliance demonstration includes the calculations according to 
Sec. 63.4741 and supporting documentation showing that during the 
initial compliance period, you used no coating with an organic HAP 
content that exceeded the applicable emission limit in Sec. 63.4690, and 
that you used no thinners or cleaning materials that contained organic 
HAP.



Sec. 63.4741  How do I demonstrate initial compliance with the emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source. You must use 
either the emission rate without add-on controls option or the emission 
rate with add-on controls option for any coating operation in the 
affected source for which you do not use this option. To demonstrate 
initial compliance using the compliant material option, the coating 
operation or group of coating operations must use no coating with an 
organic HAP content that exceeds the applicable emission limit in 
Sec. 63.4690 and must use no thinner or cleaning material that contains 
organic HAP as determined according to this section. Any coating 
operation for which you use the compliant material option is not 
required to meet the operating limits or work practice standards 
required in Secs. 63.4692 and 63.4693, respectively. To demonstrate 
initial compliance with the emission limitations using the compliant 
material option, you must meet all the requirements of this section for 
the coating operation or group of coating operations using this option. 
Use the procedures in this section on each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration.

[[Page 397]]

You do not need to redetermine the mass of organic HAP in coatings, 
thinners, or cleaning materials that have been reclaimed onsite and 
reused in the coating operation(s) for which you use the compliant 
material option, provided these materials in their condition as received 
were demonstrated to comply with the compliant material option. If the 
mass fraction of organic HAP of a coating equals zero, determined 
according to paragraph (a) of this section, and you use the compliant 
material option, you are not required to comply with paragraphs (b) and 
(c) of this section for that coating.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test. If these values cannot be determined using 
Method 311, the owner or operator shall submit an alternative technique 
for determining their values for approval by the Administrator.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for OSHA-defined carcinogens as specified in 29 
CFR 1910.1200(d)(4), and at 1.0 percent by mass or more for other 
organic HAP compounds. For example, if toluene (not an OSHA carcinogen) 
is measured to be 0.5 percent of the material by mass, you do not have 
to count it. Express the mass fraction of each organic HAP you count as 
a value truncated to four places after the decimal point (e.g., 
0.379178412 truncates to 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (e.g., 
0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP. (Note: Method 24 is not appropriate for those coatings with a water 
content that would result in an effective detection limit greater than 
the applicable emission limit.)
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4), and at 1.0 percent 
by mass or more for other organic HAP compounds. For example, if toluene 
(not an OSHA carcinogen) is 0.5 percent of the material by mass, you do 
not have to count it. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence unless, after consultation, a regulated source could 
demonstrate to the satisfaction of the enforcement agency that the 
formulation data were correct.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 5 or Table 6 to this subpart. If you use 
the tables, you must use the values in Table 5 for all solvent blends 
that match Table 5 entries, and you may only use Table 6 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 5 and

[[Page 398]]

you only know whether the blend is aliphatic or aromatic. However, if 
the results of a Method 311 (40 CFR part 63, appendix A) test indicate 
higher values than those listed on Table 5 or Table 6 to this subpart, 
the Method 311 results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by one of the methods specified in 
paragraph (b)(1), (2), or (3) of this section.
    (1) ASTM Method D2697-86 (Reapproved 1998) or D6093-97. You may use 
ASTM Method D2697-86 (Reapproved 1998), ``Standard Test Method for 
Volume Nonvolatile Matter in Clear or Pigmented Coatings' (incorporated 
by reference, see Sec. 63.14), or D6093-97, ``Standard Test Method for 
Percent Volume Nonvolatile Matter in Clear or Pigmented Coatings Using a 
Helium Gas Pycnometer'' (incorporated by reference, see Sec. 63.14), to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to 
calculate volume fraction of coating solids. If these values cannot be 
determined using these methods, the owner operator may submit an 
alternative technique for determining their values for approval by the 
Administrator.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:

grams volatile matter per liter volatile matter, determined from test 
results using ASTM Method D1475-90 information from the supplier or 
manufacturer of the material, or reference sources providing density or 
specific gravity data for pure materials. If there is disagreement 
between ASTM Method D1475-90 test results and other information sources, 
the test results will take precedence.
    (c) Determine the density of each coating. Determine the density of 
each coating used during the compliance period from test results using 
ASTM Method D1475-90 or information from the supplier or manufacturer of 
the material. If there is disagreement between ASTM Method D1475-90 test 
results and the supplier's or manufacturer's information, the test 
results will take precedence.
    (d) Calculate the organic HAP content of each coating. Calculate the 
organic HAP content, grams organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.001

Where:

Hc = Organic HAP content of the coating, grams organic HAP 
per liter coating solids.
Dc = Density of coating, grams coating per liter coating, 
determined according to paragraph (c) of this section.

[[Page 399]]

    (e) Compliance demonstration. The organic HAP content for each 
coating used during the initial compliance period, determined using 
Equation 2 of this section, must be less than or equal to the applicable 
emission limit in Sec. 63.4690; and each thinner and cleaning material 
used during the initial compliance period must contain no organic HAP, 
determined according to paragraph (a) of this section. You must keep all 
records required by Secs. 63.4730 and 63.4731. As part of the 
Notification of Compliance Status required in Sec. 63.4710, you must 
identify the coating operation(s) for which you used the compliant 
material option and submit a statement that the coating operation(s) was 
(were) in compliance with the emission limitations during the initial 
compliance period because you used no coatings for which the organic HAP 
content exceeded the applicable emission limit in Sec. 63.4690, and you 
used no thinners or cleaning materials that contained organic HAP, 
determined according to paragraph (a) of this section.



Sec. 63.4742  How do I demonstrate continuous compliance with the emission limitations?

    (a) For each compliance period to demonstrate continuous compliance, 
you must use no coating for which the organic HAP content determined 
using Equation 2 of Sec. 63.4741 exceeds the applicable emission limit 
in Sec. 63.4690; and use no thinner or cleaning material that contains 
organic HAP, determined according to Sec. 63.4741(a). A compliance 
period consists of 12 months. Each month after the end of the initial 
compliance period described in Sec. 63.4740 is the end of a compliance 
period consisting of that month and the preceding 11 months.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Secs. 63.4710(c)(6) and 63.4720(a)(5).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4720, you must identify the coating operation(s) for which you 
used the compliant material option. If there were no deviations from the 
emission limitations in Sec. 63.4690, submit a statement that the 
coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because you used no coating for 
which the organic HAP content exceeded the applicable emission limit in 
Sec. 63.4690, and you used no thinner or cleaning material that 
contained organic HAP, determined according to Sec. 63.4741(a).
    (d) You must maintain records as specified in Secs. 63.4730 and 
63.4731.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4750  By what date must I conduct the initial compliance demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 63.4751. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4683 and ends on the last day of the 12th month 
following the compliance date. If the compliance date occurs on any day 
other than the first day of a month, then the initial compliance period 
extends through the end of that month plus the next 12 months. You must 
determine the mass of organic HAP emissions and volume of coating solids 
used each month and then calculate a 12-month organic HAP emission rate 
at the end of the initial 12-month compliance period. The initial 
compliance demonstration includes the calculations according to 
Sec. 63.4751 and supporting documentation showing that during the 
initial compliance period the organic HAP emission rate was equal to or 
less than the applicable emission limit in Sec. 63.4690.



Sec. 63.4751  How do I demonstrate initial compliance with the emission limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source. You must

[[Page 400]]

use either the compliant material option or the emission rate with add-
on controls option for any coating operation in the affected source for 
which you do not use this option. To demonstrate initial compliance 
using the emission rate without add-on controls option, the coating 
operation or group of coating operations must meet the applicable 
emission limit in Sec. 63.4690. Any coating operation for which you use 
the emission rate without add-on controls option is not required to meet 
the operating limits or work practice standards required in 
Secs. 63.4692 and 63.4693, respectively. You must meet all the 
requirements of this section to demonstrate initial compliance with the 
applicable emission limit in Sec. 63.4690 for the coating operation(s). 
When calculating the organic HAP emission rate according to this 
section, do not include any coatings, thinners, or cleaning materials 
used on coating operations for which you use the compliant material 
option or the emission rate with add-on controls option. You do not need 
to redetermine the mass of organic HAP in coatings, thinners, or 
cleaning materials that have been reclaimed onsite and reused in the 
coating operation(s) for which you use the emission rate without add-on 
controls option.
    (a) Determine the mass fraction of organic HAP for each material.

coating. Determine the volume fraction of coating solids for each 
coating used during each month according to the requirements in 
Sec. 63.4741(b).
    (c) Determine the density of each material. Determine the density of 
each coating, thinner, and cleaning material used during each month from 
test results using ASTM Method D1475-90, information from the supplier 
or manufacturer of the material, or reference sources providing density 
or specific gravity data for pure materials. If there is disagreement 
between ASTM Method D1475-90 test results and such other information 
sources, the test results will take precedence.
    (d) Determine the volume of each material used. Determine the volume 
(liters) of each coating, thinner, and cleaning material used during 
each month by measurement or usage records.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all 
coatings, thinners, and cleaning materials used during each month minus 
the organic HAP in certain waste materials. Calculate it using Equation 
1 of this section.

to paragraphs (e)(4)(i) through (iv) of this section.
    (i) You may include in the determination only waste materials that 
are generated by coating operations for which you use Equation 1 of this 
section and that will be treated or disposed of by a facility regulated 
as a TSDF under 40 CFR part 262, 264, 265, or 266. The TSDF may be 
either off-site or on-site. You may not include organic HAP contained in 
wastewater.
    (ii) You must determine either the amount of the waste materials 
sent to a TSDF during the month or the amount collected and stored 
during the month and designated for future transport to a TSDF. Do not 
include in your determination any waste materials sent to a TSDF during 
a month if you have already included them in the amount collected and 
stored during that month or a previous month.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(4)(ii) of this section.
    (iv) You may use any reasonable methodology to determine the amount

you must document your methodology as required in Sec. 63.4730(h). To 
the extent that waste manifests include this information, they may be 
used as part of the documentation of the amount of waste materials and 
mass of organic HAP contained in them.
    (f) Calculate the total volume of coating solids used. Determine the 
total volume of coating solids used which is the combined volume of 
coating solids for all the coatings used during each month, using

    (h) Compliance demonstration. The organic HAP emission rate for the 
initial 12-month compliance period, calculated using Equation 3 of this 
section, must be less than or equal to the applicable emission limit in 
Sec. 63.4690. You must keep all records as required by Secs. 63.4730 and 
63.4731. As part of the Notification of Compliance Status required by 
Sec. 63.4710, you must identify the coating operation(s) for which you 
used the emission rate without add-on controls option and submit a 
statement that the coating operation(s) was (were) in compliance with 
the emission limitations during the initial compliance period because

Sec. 63.4752  How do I demonstrate continuous compliance with the emission limitations?

    (a) To demonstrate continuous compliance, the organic HAP emission 
rate for each compliance period, calculated using Equation 3 of 
Sec. 63.4751, must be less than or equal to the applicable emission 
limit in Sec. 63.4690. A compliance period consists of 12 months. Each 
month after the end of the initial compliance period described in 
Sec. 63.4750 is the end of a compliance period consisting of that month 
and the preceding 11 months. You must perform the calculations in 
Sec. 63.4751(a) through (g) on a monthly basis using data from the 
previous 12 months of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4690, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Secs. 63.4710(c)(6) and 63.4720(a)(6).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4720, you must identify the coating operation(s) for which you 
used the emission rate without add-on controls option. If there were no 
deviations from the emission limitations, you must submit a statement 
that the coating operation(s) was (were) in compliance with the emission 
limitations during the reporting period because the organic HAP emission 
rate for each compliance

[[Page 403]]

period was less than or equal to the applicable emission limit in 
Sec. 63.4690, determined according to Sec. 63.4751(a) through (g).

emission capture system and add-on control device required by 
Sec. 63.4692 until after you have completed the performance tests 
specified in paragraph (a)(1) of this section. Instead, you must 
maintain a log detailing the operation and maintenance of the emission 
capture system, add-on control device, and continuous parameter monitors 
during the period between the compliance date and the performance test. 
You must begin complying with the operating limits for your affected 
source on the date you complete the performance tests specified in

Sec. 63.4761  How do I demonstrate initial compliance?

    (a) You may use the emission rate with add-on controls option for 
any coating operation, for any group of coating operations in the 
affected source, or for all of the coating operations in the affected 
source. You may include both controlled and uncontrolled coating 
operations in a group for which you use this option. You must use either 
the compliant material option or the emission rate without add-on 
controls option for any coating operation in the affected source for 
which you do not use the emission rate with add-on controls option. To 
demonstrate initial compliance, the coating operation(s) for which you 
use the emission rate with add-on controls option must meet the 
applicable emission limitations in Secs. 63.4690, 63.4692, and 63.4693. 
You must meet all the requirements of this section to demonstrate 
initial compliance with the emission limitations. When calculating the 
organic HAP emission rate according to this section, do not include any 
coatings, thinners, or cleaning materials used on coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option. You do not need to redetermine the mass of 
organic HAP in coatings, thinners, or cleaning materials that have been 
reclaimed and reused in the coating operation(s) for which you use the 
emission rate with add-on controls option.
    (b) Compliance with operating limits. Except as provided in 
Sec. 63.4760(a)(4), and except for solvent recovery systems for which 
you conduct liquid-liquid material balances according to the 
requirements of Sec. 63.4761(j), you must establish and demonstrate 
continuous compliance during the initial compliance period with the 
operating limits required by Sec. 63.4692, using the procedures 
specified in Secs. 63.4767 and 63.4768.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4693 during the initial compliance period, as 
specified in Sec. 63.4730.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (n) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.4690.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow

[[Page 405]]

the procedures specified in Sec. 63.4751(a) through (d) to determine the 
mass fraction of organic HAP, density, and volume of each coating, 
thinner, and cleaning material used during each month; and the volume 
fraction of coating solids for each coating used during each month.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4751, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during each month in the coating 
operation or group of coating operations for which you use the emission 
rate with add-on controls option.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each month. The emission 
reduction determination quantifies the total organic HAP emissions that 
pass through the emission capture system and are destroyed or removed by 
the add-on control device. Use the procedures in paragraph (h) of this 
section to calculate the mass of organic HAP emission reduction for each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances. For each controlled coating 
operation using a solvent recovery system for which you conduct a 
liquid-liquid material balance, use the procedures in paragraph (j) of 
this section to calculate the organic HAP emission reduction.
    (h) Calculate the organic HAP emission reduction for each controlled 
coating operation not using liquid-liquid material balances. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction, using Equation 1 of this section. The calculation 
applies the emission capture system efficiency and add-on control device 
efficiency to the mass of organic HAP contained in the coatings,

served by the emission capture system and add-on control device during 
each month. For any period of time a deviation specified in 
Sec. 63.4763(c) or (d) occurs in the controlled coating operation, 
including a deviation during a period of SSM, you must assume zero 
efficiency for the emission capture system and add-on control device. 
Equation 1 of this section treats the materials used during such a 
deviation as if they were used on an uncontrolled coating operation for 
the time period of the deviation.

Secs. 63.4730 and 63.4731. As part of the Notification of Compliance 
Status required by Sec. 63.4710, you must identify the coating 
operation(s) for which you used the emission rate with add-on controls 
option and submit a statement that the coating operation(s) was (were) 
in compliance with the emission limitations during the initial 
compliance period because the organic HAP emission rate was less than or 
equal to the applicable emission limit in Sec. 63.4690, and you achieved 
the operating limits required by Sec. 63.4692 and the work practice 
standards required by Sec. 63.4693.



Sec. 63.4762  [Reserved]



Sec. 63.4763  How do I demonstrate continuous compliance with the emission limitations?

    (a) To demonstrate continuous compliance with the applicable 
emission limit in Sec. 63.4690, the organic HAP

[[Page 411]]

emission rate for each compliance period, calculated using Equation 5 of 
Sec. 63.4761, must be equal to or less than the applicable emission 
limit in Sec. 63.4690. A compliance period consists of 12 months. Each 
month after the end of the initial compliance period described in 
Sec. 63.4760 is the end of a compliance period consisting of that month 
and the preceding 11 months. You must perform the calculations in 
Sec. 63.4761 on a monthly basis using data from the previous 12 months 
of operation.
    (b) If the organic HAP emission rate for any 12-month compliance 
period exceeded the applicable emission limit in Sec. 63.4690, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Secs. 63.4710(c)(6) and 63.4720(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4692 that applies to you, as specified in 
Table 3 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 3 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Secs. 63.4710(c)(6) and 
63.4720(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 3 to this subpart, then you must assume that the 
emission capture system and add-on control device were achieving zero 
efficiency during the time period of the deviation. For the purposes of 
completing the compliance calculations specified in Sec. 63.4761(h), you 
must treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation, as indicated in Equation 1 of 
Sec. 63.4761.
    (d) You must meet the requirements for bypass lines in 
Sec. 63.4768(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when a controlled coating 
operation is running, this is a deviation that must be reported as 
specified in Secs. 63.4710(c)(6) and 63.4720(a)(7). For the purposes of 
completing the compliance calculations specified in Sec. 63.4761(h), you 
must treat the materials used during a deviation on a controlled coating 
operation as if they were used on an uncontrolled coating operation for 
the time period of the deviation, as indicated in Equation 1 of 
Sec. 63.4761.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4693. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4730(k)(8), this is a deviation from the 
work practice standards that must be reported as specified in 
Secs. 63.4710(c)(6) and 63.4720(a)(7).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4720, you must identify the coating operation(s) for which you 
used the emission rate with add-on controls option. If there were no 
deviations from the emission limitations, submit a statement that you 
were in compliance with the emission limitations during the reporting 
period because the organic HAP emission rate for each compliance period 
was less than or equal to the applicable emission limit in Sec. 63.4690, 
and you achieved the operating limits required by Sec. 63.4692 and the 
work practice standards required by Sec. 63.4693 during each compliance 
period.
    (g) During periods of SSM of the emission capture system, add-on 
control device, or coating operation that may affect emission capture or 
control device efficiency, you must operate in accordance with the SSMP 
required by Sec. 63.4700(d).
    (h) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of SSM of the emission capture system, add-on 
control device, or coating operation that may affect emission capture or 
control device efficiency are not violations if you demonstrate to the 
Administrator's satisfaction that you were operating in accordance with 
the SSMP. The Administrator will determine whether deviations that occur 
during a period you identify as an SSM are violations, according to the 
provisions in Sec. 63.6(e).
    (i) [Reserved]
    (j) You must maintain records as specified in Secs. 63.4730 and 
63.4731.

[[Page 412]]



Sec. 63.4764  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4760 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of SSM, and during 
periods of nonoperation do not constitute representative conditions. You 
must record the process information that is necessary to document 
operating conditions during the test and explain why the conditions 
represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4765. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4766.



Sec. 63.4765  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4760.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system; and the removal or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours in duration or the length of a production run, whichever 
is longer, up to 8 hours. For the purposes of this test, a production 
run means the time required for a single part to go from the beginning 
to the end of production, which includes surface preparation activities 
and drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture

[[Page 413]]

devices collect emissions for routing to an add-on control device, such 
as the entrance and exit areas of an oven or spray booth, must also be 
inside the enclosure. The enclosure must meet the applicable definition 
of a temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction of TVH liquid input from each coating, 
thinner, and cleaning material used in the coating operation during each 
capture efficiency test run. To make the determination, substitute TVH 
for each occurrence of the term volatile organic compounds (VOC) in the 
methods.
    (3) Use Equation 1 of this section to calculate the total mass of 
TVH liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run.
[GRAPHIC] [TIFF OMITTED] TR98AD03.020

Where:

TVHused = Mass of liquid TVH in materials used in the coating 
operation during the capture efficiency test run, grams.
TVHi = Mass fraction of TVH in coating, thinner, or cleaning 
material, i, that is used in the coating operation during the capture 
efficiency test run, grams TVH per gram material.
Voli = Total volume of coating, thinner, or cleaning 
material, i, used in the coating operation during the capture efficiency 
test run, liters.
Di = Density of coating, thinner, or cleaning material, i, 
grams material per liter material.
n = Number of different coatings, thinners, and cleaning materials used 
in the coating operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass, grams, of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.

    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.021

Where:

CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHused = Total mass of TVH liquid input used in the coating 
operation during the capture efficiency test run, grams.

[[Page 414]]

TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
grams, determined according to paragraph (c)(4) of this section.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, grams, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C of appendix M to 
40 CFR part 51 measurement must be upstream from the add-on control 
device and must represent total emissions routed from the capture system 
and entering the add-on control device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, grams, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the coating operation for which capture 
efficiency is being determined, must be shut down, but all fans and 
blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.022


[[Page 415]]


Where:

CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, grams, determined 
according to paragraph (d)(2) of this section.
TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
grams, determined according to paragraph (d)(3) of this section.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4766  How do I determine the add-on control device emission destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.4760. You 
must conduct three test runs as specified in Sec. 63.7(e)(3), and each 
test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC 19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, 
Instruments and Apparatus]'' (incorporated by reference, see 
Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be more than 50 parts per million (ppm) at 
the control device outlet.
    (2) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (3) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high volume dilute stream outlet of the concentrator.

[[Page 416]]

    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR98AD03.023

Where:

Mf = Total gaseous organic emissions mass flow rate, grams 
per hour (h).
Cc = Concentration of organic compounds as carbon in the vent 
gas, as determined by Method 25 or Method 25A, parts per million by 
volume (ppmv), dry basis.
Qsd = Volumetric flow rate of gases entering or exiting the 
add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, 
dry standard cubic meters/hour (dscm/h).
41.6 = Conversion factor for molar volume, gram-moles per cubic meter 
(mol/m3) (@ 293 Kelvin (K) and 760 millimeters of mercury 
(mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR98AD03.024

Where:

DRE = Organic emissions destruction or removal efficiency of the add-on 
control device, percent.
Mfi = Total gaseous organic emissions mass flow rate at the 
inlet(s) to the add-on control device, using Equation 1 of this section, 
grams/h.
Mfo = total gaseous organic emissions mass flow rate at the 
outlet(s) of the add-on control device, using Equation 1 of this 
section, grams/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4767  How do I establish the emission capture system and add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4760 and described 
in Secs. 63.4764, 63.4765, and 63.4766, you must establish the operating 
limits required by Sec. 63.4692 according to this section, unless you 
have received approval for alternative monitoring and operating limits 
under Sec. 63.8(f) as specified in Sec. 63.4692.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.

[[Page 417]]

    (2) Use the data collected during the performance test to calculate 
and record the average temperature difference across the catalyst bed 
maintained during the performance test. This is the minimum operating 
limit for your catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature before the catalyst bed at least once every 
15 minutes during each of the three test runs. Use the data collected 
during the performance test to calculate and record the average 
temperature before the catalyst bed during the performance test. This is 
the minimum operating limit for your catalytic oxidizer. (Note: For 
regenerative catalytic oxidizers, the inlet to the catalyst is defined 
as the general zone between the inlets to the catalyst beds located in 
the multiple regeneration towers; select either a monitoring location or 
multiple monitoring locations. If multiple monitoring locations are 
selected, either establish separate operating limits for each location 
or calculate an average of the multiple measurements and set a single 
operating limit.)
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e, 
conversion efficiency) following the recommended procedures from the 
manufacturer, the catalyst supplier, or the catalyst test provider.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendation and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.4766.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle, 
and the maximum carbon bed temperature recorded after the cooling cycle.
    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (e)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the

[[Page 418]]

desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (f) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4765(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (f)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 3 to this subpart.
    (1) During the capture efficiency determination required by 
Sec. 63.4760 and described in Secs. 63.4764 and 63.4765, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.4768  What are the requirements for continuous parameter monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), (f), and (g) of this section according 
to paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during periods when the control device is 
not receiving emissions, monitoring malfunctions, associated repairs, 
out-of-control periods, or required quality assurance or control 
activities when calculating data averages. You must use all the data 
collected during all other periods in calculating the data averages for 
determining compliance with the emission capture system and add-on 
control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling

[[Page 419]]

the bypass line in a nondiverting position in such a way that the valve 
or closure mechanism cannot be opened without creating a record that the 
valve was opened. The method used to monitor or secure the valve or 
closure mechanism must meet one of the requirements specified in 
paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (non-diverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (2) If any bypass line is opened and there was a deviation from the 
applicable emission limitation, you must include a description of why 
the bypass line was opened and the length of time it remained open in 
the semiannual compliance reports required in Sec. 63.4720.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, you must install a gas temperature 
monitor in the gas stream immediately before the catalyst bed, and if 
you established operating limits according to Sec. 63.4767(b)(1) and 
(2), also install a gas temperature monitor in the gas stream 
immediately after the catalyst bed.
    (i) If you establish operating limits according to 
Sec. 63.4767(b)(1) and (2), then you must install the gas temperature 
monitors both upstream and downstream of the catalyst bed. The 
temperature monitors must be in the gas stream immediately before and 
after the catalyst bed to measure the temperature difference across the 
bed.
    (ii) If you establish operating limits according to 
Sec. 63.4767(b)(3) and (4), then you must install a gas temperature 
monitor upstream of the catalyst bed. The temperature monitor must be in 
the gas stream immediately before the catalyst bed to measure the 
temperature.
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a) and (c)(3)(i) through (vii) of this 
section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a measurement sensitivity of 4 
degrees Fahrenheit or 0.75 percent of the temperature value, whichever 
is larger.

[[Page 420]]

    (iii) Shield the temperature sensor system from electromagnetic

    (iv) If a gas temperature chart recorder is used, it must have a 
measurement sensitivity in the minor division of at least 20 degrees 
Fahrenheit.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owners manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 30 degrees Fahrenheit of the process temperature sensor reading.
    (vi) Conduct calibration and validation checks any time the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (d) Carbon adsorbers. If you are using a carbon adsorber as an add-
on control device, you must monitor the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, the 
carbon bed temperature after each regeneration and cooling cycle, and 
comply with paragraphs (a)(3) through (5) and (d)(1) and (2) of this 
section.
    (1) The regeneration desorbing gas mass flow monitor must be an 
integrating device having a measurement sensitivity of plus or minus 10 
percent capable of recording the total regeneration desorbing gas mass 
flow for each regeneration cycle.
    (2) The carbon bed temperature monitor must have a measurement 
sensitivity of 1 percent of the temperature recorded or 1 degree 
Fahrenheit, whichever is greater, and must be capable of recording the 
temperature within 15 minutes of completing any carbon bed cooling 
cycle.
    (e) Condensers. If you are using a condenser, you must monitor the 
condenser outlet (product side) gas temperature and comply with 
paragraphs (a) and (e)(1) and (2) of this section.

of 1 percent of the temperature recorded or 1 degree Fahrenheit, 
whichever is greater.
    (2) The temperature monitor must provide a gas temperature record at

zeolite wheel or rotary carbon bed concentrator, you must comply with 
the requirements in paragraphs (f)(1) and (2) of this section.
    (1) You must install a temperature monitor in the desorption gas 
stream. The temperature monitor must meet the requirements in paragraphs 
(a) and (c)(3) of this section.
    (2) You must install a device to monitor pressure drop across the 
zeolite wheel or rotary carbon bed. The pressure monitoring device must 
meet the requirements in paragraphs (a) and (f)(2)(i) through (vii) of 
this section.
    (i) Locate the pressure sensor(s) in or as close to a position that 
provides a representative measurement of the pressure.
    (ii) Minimize or eliminate pulsating pressure, vibration, and

Sec. 63.4781  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Add-on control means an air pollution control device, such as a 
thermal oxidizer or carbon adsorber, that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    Adhesive means any chemical substance that is applied for the 
purpose of bonding two surfaces together.
    Block average is an average of data points collected over any 
specified, continuous 180-minute block of time (e.g., a 3-hour block 
could be noon to 3 p.m., with a subsequent total of eight 3-hour blocks 
within a 24-hour period).
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency or capture system efficiency means the portion 
(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.
    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings or cleaning materials occur, 
such as flashoff,

[[Page 422]]

drying, or curing. As used in this subpart, multiple capture devices 
that collect emissions generated by a coating operation are considered a 
single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting), from a substrate before or after coating application 
or from equipment associated with a coating operation, such as spray 
booths, spray guns, racks, tanks, and hangers. Thus, it includes any 
cleaning material used on substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, caulks, inks, adhesives, and maskants. 
Decorative, protective, or functional materials that consist only of

application) and to dry or cure the coating after application, or to 
clean coating operation equipment (equipment cleaning). A single coating 
operation may include any combination of these types of equipment, but 
always includes at least the point at which a coating or cleaning 
material is applied and all subsequent points in the affected source 
where organic HAP emissions from that coating or cleaning material 
occur. There may be multiple coating operations in an affected source.

this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during SSM, regardless of whether or 
not such failure is permitted by this subpart.

    Laminated wood product means any wood building product to which a 
protective, decorative, or functional layer has been bonded with an 
adhesive. Products that are produced by bonding layers to the substrate 
as a part of the substrate manufacturing process (prior to pressing) are 
not considered laminated products under this subpart.
    Manufacturer's formulation data means data on a material (such as a

[[Page 423]]

coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test methods specified in 
Sec. 63.4741. Manufacturer's formulation data may include, but are not 
limited to, information on density, organic HAP content, volatile 
organic matter content, and coating solids content.

building product or component such as door, window, and staircase 
part(s), or decorative trim.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    Organic HAP content means the mass of organic HAP per volume of 
coating solids for a coating calculated using Equation 2 of 
Sec. 63.4741. The organic HAP content is determined for the coating in 
the condition it is in when received from its manufacturer or supplier 
and does not account for any alteration after receipt.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.
    Protective oil means an organic material that is applied to metal 
for the purpose of providing lubrication or protection from corrosion 
without forming a solid film. This definition of protective oil 
includes, but is not limited to, lubricating oils, evaporative oils 
(including those that evaporate completely), and extrusion oils.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products, 
that is conducted under the close supervision of technically trained 
personnel, and is not engaged in the manufacture of final or 
intermediate products for commercial purposes, except in a de minimis 
manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Startup, initial means the first time equipment is brought online in 
a source.
    Surface preparation means use of a cleaning material on a portion of 
or all of a substrate. This includes use of a cleaning material to 
remove dried coating, which is sometimes called ``depainting.''

the coating is received from the supplier.
    Tileboard means hardboard that meets the specifications for Class I 
given by the standard ANSI/AHA A135.4-1995 as approved by the American 
National Standards Institute. The standard specifies requirements and 
test methods for water absorption, thickness swelling, modulus of 
rupture, tensile strength, surface finish, dimensions, squareness, edge 
straightness, and moisture content for five classes of hardboard. 
Tileboard is also known as Class I hardboard or tempered hardboard.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous volatile organic matter determined according to Methods 204 
and 204A through 204F of appendix M to 40 CFR part 51 and substituting 
the term TVH each place in the methods where the term VOC is used. The 
TVH includes both VOC and non-VOC.

Subpart RRRR--National Emission Standards for Hazardous Air Pollutants: 
                   Surface Coating of Metal Furniture

    Source: 68 FR 28619, May 23, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.4880  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for metal furniture surface coating facilities. 
This subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations.



Sec. 63.4881  Am I subject to this subpart?

    (a) Except as provided in paragraph (c) of this section, the source 
category to which this subpart applies is surface coating of metal 
furniture.
    (1) Surface coating is the application of coatings to a substrate 
using, for example, spray guns or dip tanks.
    (2) Metal furniture means furniture or components of furniture 
constructed either entirely or partially from metal. Metal furniture 
includes, but is not limited to, components of the following types of 
products as well as the products themselves: household, office, 
institutional, laboratory, hospital, public building, restaurant, barber 
and beauty shop, and dental furniture; office and store fixtures; 
partitions; shelving; lockers; lamps and lighting fixtures; and 
wastebaskets.
    (b) You are subject to this subpart if you own or operate a new, 
reconstructed, or existing affected source as defined in Sec. 63.4882, 
in the source category defined in paragraph (a) of this section, and 
that is a major source, is located at a major source, or is part of a 
major source of emissions of hazardous air pollutants (HAP). A major 
source of HAP emissions is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or has the potential to emit any single HAP at a rate of 9.07 
megagrams (Mg) (10 tons) or more per year or any combination of HAP at a 
rate of 22.68 Mg (25 tons) or more per year.
    (c) This subpart does not apply to surface coating that meets any of 
the criteria of paragraphs (c)(1) through (6) of this section.
    (1) Surface coating conducted at an affected source that uses only 
coatings, thinners, and cleaning materials that contain no organic HAP.
    (2) Surface coating of metal components of wood furniture conducted 
in an operation that is subject to the wood furniture manufacturing 
NESHAP in subpart JJ of this part.
    (3) Surface coating that occurs at research or laboratory facilities 
or that is part of janitorial, building, and facility maintenance 
operations.
    (4) Surface coating of only small items such as knobs, hinges, or 
screws that have a wider use beyond metal furniture are not subject to 
this subpart unless the surface coating occurs at an affected metal 
furniture source.
    (5) Surface coating of metal furniture conducted for the purpose of 
repairing or maintaining metal furniture used by

[[Page 430]]

a major source and not for commerce is not subject to this subpart, 
unless organic HAP emissions from the surface coating itself are as high 
as the rates specified in paragraph (b) of this section.
    (6) Surface coating of metal furniture performed on-site at 
installations owned or operated by the Armed Forces of the United States 
(including the Coast Guard and the National Guard of any State).



Sec. 63.4882  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, and existing 
affected source.
    (b) The affected source is the collection of all of the items listed 
in paragraphs (b)(1) through (4) of this section that are used for 
surface coating of metal furniture:
    (1) All coating operations as defined in Sec. 63.4981;
    (2) All storage containers and mixing vessels in which coatings, 
thinners, and cleaning materials are stored or mixed;
    (3) All manual and automated equipment and containers and all pumps 
and piping within the affected source used for conveying coatings, 
thinners, and cleaning materials; and
    (4) All storage containers, all pumps and piping, and all manual and 
automated equipment and containers within the affected source used for 
conveying waste materials generated by a coating operation.
    (c) An affected source is a new affected source if you commenced its 
construction after April 24, 2002, and the construction is of a 
completely new metal furniture surface coating facility where previously 
no metal furniture surface coating facility had existed.
    (d) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.4883  When do I have to comply with this subpart?

    The date by which you must comply with this subpart is called the 
compliance date. The compliance date for each type of affected source is 
specified in paragraphs (a) through (c) of this section. The compliance 
date begins the initial compliance period during which you conduct the 
initial compliance demonstration described in Secs. 63.4940, 63.4950, 
and 63.4960.
    (a) For a new or reconstructed affected source, the compliance date 
is the applicable date in paragraph (a)(1) or (2) of this section:
    (1) If the initial startup of your new or reconstructed affected 
source is before May 23, 2003, the compliance date is May 23, 2003.
    (2) If the initial startup of your new or reconstructed affected 
source occurs after May 23, 2003, the compliance date is the date of 
initial startup of your affected source.
    (b) For an existing affected source, the compliance date is the date 
3 years after May 23, 2003.
    (c) For an area source that increases its emissions or its potential 
to emit such that it becomes a major source of HAP emissions, the 
compliance date is specified in paragraphs (c)(1) and (2) of this 
section.
    (1) For any portion of the source that becomes a new or 
reconstructed affected source subject to this subpart, the compliance 
date is the date of initial startup of the affected source or May 23, 
2003, whichever is later.
    (2) For any portion of the source that becomes an existing affected 
source subject to this subpart, the compliance date is the date 1 year 
after the area source becomes a major source or 3 years after May 23, 
2003, whichever is later.
    (d) You must meet the notification requirements in Sec. 63.4910 
according to the dates specified in that section and in subpart A of 
this part. Some of the notifications must be submitted before the 
compliance dates described in paragraphs (a) through (c) of this 
section.

                          Emission Limitations



Sec. 63.4890  What emission limits must I meet?

    (a) For a new or reconstructed affected source, you must emit no 
organic HAP during each compliance period, determined according to the 
procedures in Sec. 63.4941.

[[Page 431]]

    (b) Alternative emission limit. You may request approval from the 
Administrator to use an alternative new source emission limit for 
specific metal furniture components or type of components for which you 
believe the emission limit in paragraph (a) of this section cannot be 
achieved.
    (1) Any request to use an alternative emission limit under paragraph 
(b) of this section must contain specific information demonstrating why 
no organic HAP-free coating technology can be used on the metal 
furniture components. The request must be based on objective criteria 
related to the performance or appearance requirements of the finished 
coating, which may include but is not limited to the criteria listed in 
paragraphs (b)(1)(i) through (viii) of this section.
    (i) Low dried film thickness requirements (e.g., less than 0.0254 
millimeters (0.001 inch)).
    (ii) Flexibility requirements for parts subject to repeated bending.
    (iii) Chemical resistance to withstand chemical exposure in 
environments such as laboratories.
    (iv) Resistance to the effects of exposure to ultraviolet light.
    (v) Adhesion characteristics related to the condition of the 
substrate.
    (vi) High gloss requirements.
    (vii) Custom colors such as matching the color of a corporate logo.
    (viii) Non-uniform surface finishes such as an antique appearance 
that requires visible cracking of the dried film.
    (2) If the request to use an alternative emission limit under 
paragraph (b) of this section is approved, the new source must meet an 
emission limit of 0.094 kilogram (kg) organic HAP per liter (kg/liter) 
(0.78 pounds per gallon (lb/gal)) coating solids used for only those 
components subject to the approval. All other metal furniture surface 
coating operations at the new source must meet the emission limit 
specified in paragraph (a) of this section. Until approval to use the 
alternative emission limit has been granted by the Administrator under 
this paragraph (b)(2), you must meet the emission limit specified in 
paragraph (a) of this section and all other applicable requirements in 
this subpart.
    (c) For an existing affected source, you must limit organic HAP 
emissions to the atmosphere to no more than 0.10 kg organic HAP per 
liter (0.83 lb/gal) of coating solids used during each compliance 
period, determined according to the procedures in Sec. 63.4941, 
Sec. 63.4951, or Sec. 63.4961.



Sec. 63.4891  What are my options for demonstrating compliance with the emission limits?

    You must include all coatings, thinners, and cleaning materials used 
in the affected source when determining whether the organic HAP emission 
rate is equal to or less than the applicable emission limit in 
Sec. 63.4890. To make this determination, you must use at least one of 
the three compliance options listed in paragraphs (a) through (c) of 
this section. You may apply any of the compliance options to an 
individual coating operation or to multiple coating operations as a 
group or to the entire affected source. You may use different compliance 
options for different coating operations or at different times on the 
same coating operation. However, you may not use different compliance 
options at the same time on the same coating operation. If you switch 
between compliance options for any coating operation or group of coating 
operations, you must document this switch as required by 
Sec. 63.4930(c), and you must report it in the next semiannual (6-month 
period) compliance report required in Sec. 63.4920.
    (a) Compliant material option. Demonstrate that the organic HAP 
content of each coating used in the coating operation or group of 
coating operations is less than or equal to the applicable emission rate 
limit in Sec. 63.4890 and that each thinner and each cleaning material 
used contains no organic HAP. You must meet all the requirements of 
Secs. 63.4940, 63.4941, and 63.4942 to demonstrate compliance with the 
emission limit using this option.
    (b) Emission rate without add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation

[[Page 432]]

or group of coating operations, the organic HAP emission rate for the 
coating operation or group of coating operations is less than or equal 
to the applicable emission rate limit in Sec. 63.4890, calculated as a 
monthly emission rate. You must meet all the requirements of 
Secs. 63.4950, 63.4951, and 63.4952 to demonstrate compliance with the 
emission rate limit using this option.
    (c) Emission rate with add-on controls option. Demonstrate that, 
based on the coatings, thinners, and cleaning materials used in the 
coating operation or group of coating operations, and the emission 
reductions achieved by emission capture and add-on control systems, the 
organic HAP emission rate is less than or equal to the applicable 
emission rate limit in Sec. 63.4890, calculated as a monthly emission 
rate. If you use this compliance option, you must also demonstrate that 
all capture systems and add-on control devices for the coating operation 
or group of coating operations meet the operating limits required in 
Sec. 63.4892, except for solvent recovery systems for which you conduct 
liquid-liquid material balances according to Sec. 63.4961(j); and that 
you meet the work practice standards required in Sec. 63.4893. You must 
meet all the requirements of Secs. 63.4960 through 63.4967 to 
demonstrate compliance with the emission limits, operating limits, and 
work practice standards using this option.
    (d) If you choose to use the emission rate with add-on controls 
compliance option in paragraph (c) of this section and operate the 
coating operation, its emission capture system, or its add-on control 
device at multiple sets of representative operating conditions that 
result in different capture system or add-on control device efficiencies 
during a compliance period, you must follow one of the procedures in 
paragraph (d)(1) or (2) of this section.
    (1) Determine the operating conditions that result in the lowest 
emission capture system and add-on control device efficiencies through 
performance testing conducted according to Secs. 63.4963, 63.4964, and 
63.4965. Use these emission capture system and add-on control device 
efficiencies for all representative operating conditions during the 
compliance period.
    (2) Develop a compliance calculation procedure for determining the 
organic HAP emission rate for the compliance period that takes into 
account all of the representative operating conditions the source was 
operated under during the compliance period and submit the procedure to 
the Administrator for approval. Until you receive approval from the 
Administrator, you must determine compliance according to paragraph (c) 
of this section.



Sec. 63.4892  What operating limits must I meet?

    (a) For any coating operation or group of coating operations for 
which you use the compliant material option or the emission rate without 
add-on controls option to demonstrate compliance, you are not required 
to meet any operating limits.
    (b) For any coating operation or group of coating operations for 
which you use the emission rate with add-on controls option to 
demonstrate compliance, except those for which you use a solvent 
recovery system and conduct a liquid-liquid material balance according 
to Sec. 63.4961(j), you must meet the operating limits specified in 
Table 1 to this subpart. These operating limits apply to the emission 
capture and control systems on the coating operation or group of coating 
operations for which you use emission capture and add-on controls to 
demonstrate compliance. You must establish the operating limits during 
the performance test according to the requirements in Sec. 63.4966. You 
must meet the operating limits at all times after you establish them.
    (c) If you use an add-on control device other than those listed in 
Table 1 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 63.8(f).



Sec. 63.4893  What work practice standards must I meet?

    (a) For any coating operation or group of coating operations for 
which you use the compliant material option or the emission rate without 
add-on

[[Page 433]]

controls option to demonstrate compliance, you are not required to meet 
any work practice standards.
    (b) For any coating operation or group of coating operations for 
which you use the emission rate with add-on controls option to 
demonstrate compliance, you must develop and implement a work practice 
plan to minimize organic HAP emissions from the storage, mixing, and 
conveying of coatings, thinners, and cleaning materials used in, and 
waste materials generated by, the coating operation or group of coating 
operations for which you use this option; or you must meet an 
alternative standard as provided in paragraph (c) of this section. The 
plan must specify practices and procedures to ensure that, at a minimum, 
the elements specified in paragraphs (b)(1) through (5) of this section 
are implemented.
    (1) All organic-HAP-containing coatings, thinners, cleaning 
materials, and waste materials must be stored in closed containers. You 
must ensure that these containers are kept closed at all times except 
when depositing or removing these materials from the container.

        Compliance Requirements for the Compliant Material Option



Sec. 63.4940  By what date must I conduct the initial compliance demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements in Sec. 63.4941. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4883 and ends on the last day of the first full 
month following the compliance date. The initial compliance 
demonstration includes the calculations according to Sec. 63.4941 and 
supporting documentation showing that, during the initial compliance 
period, you used no coating with an organic HAP content that exceeded 
the applicable emission limit in Sec. 63.4890, and you used no thinners 
or cleaning materials that contained organic HAP.



Sec. 63.4941  How do I demonstrate initial compliance with the emission limitations?

    You may use the compliant material option for any individual coating 
operation, for any group of coating operations in the affected source, 
or for all the coating operations in the affected source to demonstrate 
compliance with an organic HAP emission limit. You must use either the 
emission rate without add-on controls option or the emission rate with 
add-on controls option for any coating operation in the affected source 
for which you do not use this option. To demonstrate initial compliance 
using the compliant material option, during the compliance period the 
coating operation or group of coating operations must use no coating 
with an organic HAP content that exceeds the applicable emission limit 
in Sec. 63.4890 and must use no thinner or cleaning material that 
contains organic HAP as determined according to this section. Any 
coating operation for which you use the compliant material option is not 
required to comply with the operating limits or work practice standards 
required in Secs. 63.4892 and 63.4893, respectively. To demonstrate 
initial compliance with the emission limitations using the compliant 
material option, you must meet all the requirements of this section for 
the coating operation or group of coating operations using this option. 
Use the procedures in this section for each coating, thinner, and 
cleaning material in the condition it is in when it is received from its 
manufacturer or supplier and prior to any alteration. You do not need to 
redetermine the organic HAP content of cleaning materials that are 
reclaimed and reused onsite provided these materials in their condition 
as received were demonstrated to comply with the compliant material 
option.
    (a) Determine the mass fraction of organic HAP for each material 
used. You must determine the mass fraction of organic HAP for each 
coating, thinner, and cleaning material used during the compliance 
period by using one of the options in paragraphs (a)(1) through (5) of 
this section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for

[[Page 442]]

determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
performing a Method 311 test.
    (i) Count each organic HAP that is measured to be present at 0.1 
percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent of the material by mass, you do not have to count it. 
Express the mass fraction of each organic HAP you count as a value 
truncated to four places after the decimal point (for example, 0.3791).
    (ii) Calculate the total mass fraction of organic HAP in the test 
material by adding up the individual organic HAP mass fractions and 
truncating the result to three places after the decimal point (for 
example, 0.763).
    (2) Method 24 (appendix A to 40 CFR part 60). For coatings, you may 
use Method 24 to determine the mass fraction of nonaqueous volatile 
matter and use that value as a substitute for mass fraction of organic 
HAP.
    (3) Alternative method. You may use an alternative test method for 
determining the mass fraction of organic HAP once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (3) of this section, such 
as manufacturer's formulation data, if it represents each organic HAP 
that is present at 0.1 percent by mass or more for OSHA-defined 
carcinogens as specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by 
mass or more for other organic HAP compounds. For example, if toluene 
(not an OSHA carcinogen) is 0.5 percent of the material by mass, you do 
not have to count it. If there is a disagreement between such 
information and results of a test conducted according to paragraphs 
(a)(1) through (3) of this section, then the test method results will 
take precedence.
    (5) Solvent blends. Solvent blends may be listed as single 
components for some materials in data provided by manufacturers or 
suppliers. Solvent blends may contain organic HAP which must be counted 
toward the total organic HAP mass fraction of the materials. When test 
data and manufacturer's data for solvent blends are not available, you 
may use the default values for the mass fraction of organic HAP in these 
solvent blends listed in Table 3 or 4 to this subpart. If you use the 
tables, you must use the values in Table 3 for all solvent blends that 
match Table 3 entries, and you may only use Table 4 if the solvent 
blends in the materials you use do not match any of the solvent blends 
in Table 3, and you only know whether the blend is aliphatic or 
aromatic. However, if the results of a Method 311 test indicate higher 
values than those listed on Table 3 or 4 of this subpart, the Method 311 
results will take precedence.
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids 
(liters of coating solids per liter of coating) for each coating used 
during the compliance period by a test or by information provided by the 
supplier or the manufacturer of the material, as specified in paragraphs 
(b)(1), (2), and (3) of this section. If test results obtained according 
to paragraph (b)(1) of this section do not agree with the information 
obtained under paragraph (b)(2) or (3) of this section, the test results 
will take precedence.
    (1) Test results. You may use ASTM Method D2697-86 (Reapproved 
1998), ``Standard Test Method for Volume Nonvolatile Matter in Clear or 
Pigmented Coatings'' (incorporated by reference, see Sec. 63.14), or 
D6093-97, ``Standard Test Method for Percent Volume Nonvolatile Matter 
in Clear or Pigmented Coatings Using a Helium Gas Pycnometer'' 
(incorporated by reference, see Sec. 63.14), to determine the volume 
fraction of coating solids for each coating. Divide the nonvolatile 
volume percent obtained with the methods by 100 to calculate volume 
fraction of coating solids. Alternatively, you may use another test

[[Page 443]]

method once you obtain approval from the Administrator according to the 
requirements of Sec. 63.7(f).
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. If the volume 
fraction of coating solids cannot be determined using the options in 
paragraphs (b)(1) and (2) of this section, you must determine it using 
Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.019

Where:
Vs = Volume fraction of coating solids, liters coating solids 
per liter coating.
Mvolatiles = Total volatile matter content of the coating, 
including HAP, volatile organic compounds (VOC), water, and exempt 
compounds, determined according to Method 24 in appendix A of 40 CFR 
part 60, grams volatile matter per liter coating.
Davg = Average density of volatile matter in the coating, 
grams volatile matter per liter volatile matter, determined from test 
results using ASTM Method D1475-90, information from the supplier or 
manufacturer of the material, or reference sources providing density or 
specific gravity data for pure materials. If there is disagreement 
between ASTM Method D1475-90 test results and other information sources, 
the test results will take precedence.

    (c) Determine the density of each coating. You must determine the 
density of each coating used during the compliance period from test 
results using ASTM Method D1475-90 or information from the supplier or 
manufacturer of the material. If there is disagreement between ASTM 
Method D1475-90 test results and the supplier's or manufacturer's 
information, the test results will take precedence.
    (d) Calculate the organic HAP content of each coating. Calculate the 
organic HAP content, kg organic HAP per liter coating solids, of each 
coating used during the compliance period, using Equation 2 of this 
section, except that if the mass fraction of organic HAP in the coating 
equals zero, then the organic HAP content also equals zero and you are 
not required to use Equation 2 to calculate the organic HAP content.
[GRAPHIC] [TIFF OMITTED] TR23MY03.020

Where:
Hc = Organic HAP content of the coating, kg organic HAP per 
liter coating solids.
Dc = Density of coating, kg coating per liter coating, 
determined according to paragraph (c) of this section.
Wc = Mass fraction of organic HAP in the coating, kg organic 
HAP per kg coating, determined according to paragraph (a) of this 
section.
Vs = Volume fraction of coating solids, liter coating solids 
per liter coating, determined according to paragraph (b) of this 
section.

    (e) Compliance demonstration. The calculated organic HAP content for 
each coating used during the initial compliance period must be less than 
or equal to the applicable emission limit in Sec. 63.4890 and each 
thinner and cleaning material used during the initial compliance period 
must contain no organic HAP, determined according to paragraph (a) of 
this section. You must keep all records required by Secs. 63.4930 and 
63.4931. As part of the Notification of Compliance Status required in 
Sec. 63.4910(c) and the semiannual compliance reports required in 
Sec. 63.4920, you must identify each coating operation and group of 
coating operations for which you used the compliant material option. If 
there were no deviations from the emission limit, include a statement 
that each was in compliance with the emission limitations during the 
initial compliance period because it used no coatings for which the 
organic HAP content exceeded the applicable emission limit in 
Sec. 63.4890, and it used no thinners or cleaning materials that 
contained organic HAP.

[[Page 444]]



Sec. 63.4942  How do I demonstrate continuous compliance with the emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in 
Sec. 63.4941(e) for each subsequent compliance period. Each month 
following the initial compliance period described in Sec. 63.4940 is a 
compliance period.
    (b) If you choose to comply with the emission limitations by using 
the compliant material option, the use of any coating, thinner, or 
cleaning material that does not meet the criteria specified in paragraph 
(a) of this section is a deviation from the emission limitations that 
must be reported as specified in Secs. 63.4910(c)(6) and 63.4920(a)(5).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4920, you must identify the coating operation or group of 
coating operations for which you used the compliant material option. If 
there were no deviations from the emission limits in Sec. 63.4890, 
submit an affirmative statement that the coating operation or group of 
coating operations was in compliance with the emission limitations 
during the reporting period because you used no coating for which the 
organic HAP content exceeded the applicable emission limit in 
Sec. 63.4890, and you used no thinner or cleaning material that 
contained organic HAP.
    (d) You must maintain records as specified in Secs. 63.4930 and 
63.4931.

 Compliance Requirements for the Emission Rate Without Add-On Controls 
                                 Option



Sec. 63.4950  By what date must I conduct the initial compliance demonstration?

    You must complete the initial compliance demonstration for the 
initial compliance period according to the requirements of Sec. 63.4951. 
The initial compliance period begins on the applicable compliance date 
specified in Sec. 63.4883 and ends on the last day of the first full 
month following the compliance date. The initial compliance 
demonstration includes the calculations showing that the organic HAP 
emission rate for the initial compliance period was equal to or less 
than the applicable emission limit in Sec. 63.4890.



Sec. 63.4951  How do I demonstrate initial compliance with the emission limitations?

    You may use the emission rate without add-on controls option for any 
individual coating operation, for any group of coating operations in the 
affected source, or for all the coating operations in the affected 
source to demonstrate compliance with an organic HAP emission limit. You 
must use either the compliant material option or the emission rate with 
add-on controls option for any coating operation in the affected source 
for which you do not use this option. To demonstrate initial compliance 
using the emission rate without add-on controls option, the coating 
operation or group of coating operations must comply with the applicable 
emission limit in Sec. 63.4890, but is not required to meet the 
operating limits or work practice standards in Secs. 63.4892 and 
63.4893, respectively. You must meet all the requirements of this 
section to demonstrate initial compliance with the applicable emission 
limit in Sec. 63.4890 for the coating operation or group of coating 
operations. When calculating the organic HAP emission rate according to 
this section, do not include any coatings, thinners, or cleaning 
materials used on coating operations for which you use the compliant 
material option or the emission rate with add-on controls option. You do 
not need to include organic HAP in coatings, thinners, or cleaning 
materials that have been reclaimed onsite and reused in the coating 
operation for which you use the emission rate without add-on controls 
option.
    (a) Determine the mass fraction of organic HAP for each material. 
You must determine the mass fraction of organic HAP for each coating, 
thinner, and cleaning material used during the compliance period 
according to the requirements in Sec. 63.4941(a).
    (b) Determine the volume fraction of coating solids for each 
coating. You must determine the volume fraction of coating solids for 
each coating used during the compliance period according to the 
requirements in Sec. 63.4941(b).

[[Page 445]]

    (c) Determine the density of each material. You must determine the 
density of each coating, thinner, and cleaning material used during the 
compliance period according to the requirements in Sec. 63.4941(c) from 
test results using ASTM Method D1475-90, information from the supplier 
or manufacturer of the material, or reference sources providing density 
or specific gravity data for pure materials. If there is disagreement 
between ASTM Method D1475-90 test results and such other information 
sources, the test results will take precedence.
    (d) Determine the volume of each material used. You must determine 
the volume (liters) of each coating, thinner, and cleaning material used 
during the compliance period by measurement or usage records.
    (e) Calculate the mass of organic HAP emissions. The mass of organic 
HAP emissions is the combined mass of organic HAP contained in all 
coatings, thinners, and cleaning materials used during the compliance 
period minus the organic HAP in certain waste materials. Use Equation 1 
of this section to calculate the mass of organic HAP emissions:
[GRAPHIC] [TIFF OMITTED] TR23MY03.021

compliance period, kg.
A = Total mass of organic HAP in the coatings used during the compliance 
period, kg, as calculated in Equation 1A of this section.

compliance period, kg, as calculated in Equation 1C of this section.
Rw = Total mass of organic HAP in waste materials sent or 
designated for shipment to a hazardous waste TSDF for treatment or 
disposal during the compliance period, kg, determined according to 
paragraph (e)(4) of this section. The mass of any waste material reused 
during the same compliance period may not be included in Rw. 
(You may assign a value of zero to Rw if you do not wish to 
use this allowance.)

    (1) Calculate the mass of organic HAP in the coatings used during 
the compliance period, using Equation 1A of this section:

in waste materials sent or designated for shipment to a hazardous waste 
TSDF in the calculation of the total mass of organic HAP emissions 
during the compliance period in Equation 1 of this section, then you 
must determine the total mass of organic HAP in waste materials sent or 
designated for shipment to a hazardous waste TSDF for treatment or 
disposal during each compliance period, according to paragraphs 
(e)(4)(i) through (iv) of this section.
    (i) You may include in the determination of the total mass of 
organic HAP in waste materials sent or designated for shipment to a 
hazardous waste TSDF for treatment or disposal during each compliance 
period only waste materials that are generated by coating operations for 
which you use Equation 1 of this section and that will be treated or 
disposed of by a facility regulated as a TSDF under 40 CFR part 262, 
264, 265, or 266. The TSDF may be either off-site or on-site. You may 
not include in the determination of the total mass of organic HAP in 
waste materials sent or designated for shipment to a hazardous waste 
TSDF for treatment or disposal during each compliance period only waste 
materials that are generated by coating operations the organic HAP 
contained in wastewater, nor the organic HAP contained in any waste 
material reused during the same compliance period.
    (ii) You must determine either the amount of the waste materials 
sent to a TSDF during the compliance period or the amount collected and 
stored during the compliance period and designated for future transport 
to a TSDF. Do not include in your determination of the total mass of 
organic HAP in waste materials sent or designated for shipment to a 
hazardous waste TSDF for treatment or disposal during each compliance 
period only waste materials that are generated by coating operations any 
waste materials sent to a TSDF during a compliance period if you have 
already included them in the amount collected and stored during that or 
a previous compliance period.
    (iii) Determine the total mass of organic HAP contained in the waste 
materials specified in paragraph (e)(4)(ii) of this section.
    (iv) You must document your methodology to determine the amount of 
waste materials and the total mass of organic HAP they contain, as 
required in Sec. 63.4930(h). To the extent that waste manifests include 
this information, they may be used as part of the documentation of the 
amount of waste materials and mass of organic HAP contained in them.
    (f) Calculate the total volume of coating solids used. Calculate the 
total volume of coating solids used, which is the combined volume of 
coating solids for all the coatings used during the compliance period, 
using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.025

Where:

compliance period, liters.
Volc,i = Total volume of coating, i, used during the 
compliance period, liters.
Vs,i = Volume fraction of coating solids for coating, i, 
liter solids per liter coating, determined according to Sec. 63.4941(b).
m = Number of coatings used during the compliance period.

    (g) Calculate the organic HAP emission rate. Calculate the organic

used during the compliance period, kg, as calculated by Equation 1 of 
this section.
Vst = Total volume of coating solids used during the 
compliance period, liters, as calculated by Equation 2 of this section.

    (h) Compliance demonstration. The calculated organic HAP emission 
rate for the initial compliance period must be less than or equal to the 
applicable emission limit in Sec. 63.4890. You must keep all records as 
required by Secs. 63.4930 and 63.4931. As part of the Notification of 
Compliance Status required by Sec. 63.4910 and the semiannual compliance 
reports required in Sec. 63.4920, you must identify the coating 
operation or group of coating operations for which you used the emission 
rate without add-on controls option. If there were no deviations from 
the emission limit, include a statement that the coating operation or 
group of coating operations was in compliance with the emission 
limitations during the initial compliance period because the organic HAP 
emission rate was less than or equal to the applicable emission limit in 
Sec. 63.4890, determined according to this section.



Sec. 63.4952  How do I demonstrate continuous compliance with the emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in 
Sec. 63.4951(h) for each subsequent compliance period. Each month 
following the initial compliance period described in Sec. 63.4950 is a 
compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4890, this is a 
deviation from the emission limitations for that compliance period and 
must be reported as specified in Secs. 63.4910(c)(6) and 63.4920(a)(6).
    (c) As part of each semiannual compliance report required by 
Sec. 63.4920, you must identify the coating operation or group of 
coating operations for which you used the emission rate without add-on 
controls option. If there were no deviations from the emission 
limitations, you must submit an affirmative statement that the coating

   Compliance Requirements for the Emission Rate With Add-On Controls 
                                 Option



Sec. 63.4960  By what date must I conduct performance tests and other initial compliance demonstrations?

    (a) New and reconstructed affected sources. For a new or 
reconstructed affected source, you must meet the requirements of 
paragraphs (a)(1) through (4) of this section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4883. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to 
Sec. 63.4961(j), you must conduct a performance test of each capture 
system and add-on control device according to Secs. 63.4963, 63.4964, 
and 63.4965, and establish the operating limits required by 
Sec. 63.4892, no later than 180 days after the applicable compliance 
date specified in Sec. 63.4883. For a solvent recovery system for which 
you conduct liquid-liquid material balances according to 
Sec. 63.4961(j), you must initiate the first material balance no later 
than 180 days after the applicable compliance date specified in 
Sec. 63.4883.

demonstration includes the results of emission capture system and add-on 
control

[[Page 448]]

device performance tests conducted according to Secs. 63.4963, 63.4964, 
and 63.4965; results of liquid-liquid material balances conducted 
according to Sec. 63.4961(j); calculations showing whether the organic

established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4967; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.4893.
    (4) You do not need to comply with the operating limits for the 
emission capture system and add-on control device required by 
Sec. 63.4892 until after you have completed the performance tests 
specified in paragraph (a)(1) of this section. Instead, you must 
maintain a log detailing the operation and maintenance of the emission 
capture system, add-on control device, and continuous parameter monitors 
during the period between the compliance date and the performance test. 
You must begin complying with the operating limits for your affected 
source on the date you complete the performance tests specified in 
paragraph (a)(1) of this section. The requirements in this paragraph 
(a)(4) do not apply to solvent recovery systems for which you conduct 
liquid-liquid material balances.
    (b) Existing affected sources. For an existing affected source, you 
must meet the requirements of paragraphs (b)(1) through (3) of this 
section.
    (1) All emission capture systems, add-on control devices, and CPMS 
must be installed and operating no later than the applicable compliance 
date specified in Sec. 63.4883. Except for solvent recovery systems for 
which you conduct liquid-liquid material balances according to

specified in Sec. 63.4883 and ends on the last day of the first full 
month following the compliance date. The initial compliance 
demonstration includes the results of emission capture system and add-on 
control device performance tests conducted according to Secs. 63.4963, 
63.4964, and 63.4965; results of liquid-liquid material balances 
conducted according to Sec. 63.4961(j); calculations showing whether the 
organic HAP emission rate for the initial compliance period was equal to 
or less than the emission limit in Sec. 63.4890(c); the operating limits 
established during the performance tests and the results of the 
continuous parameter monitoring required by Sec. 63.4967; and 
documentation of whether you developed and implemented the work practice 
plan required by Sec. 63.4893.



Sec. 63.4961  How do I demonstrate initial compliance?

    (a) When add-on controls are used. You may use the emission rate 
with add-on controls option for any coating operation, for any group of 
coating operations in the affected source, or for all of the coating 
operations in the affected source. You may include both controlled and 
uncontrolled coating operations in a group for which you use this 
option. You must use either the compliant material option or the 
emission rate without add-on controls option for any coating operation 
in the affected source for which you do not use the emission rate with 
add-on controls option. To demonstrate initial compliance, the coating 
operation or group of coating operations for which you use the emission 
rate with add-on controls option must meet the applicable emission limit 
in Sec. 63.4890, and each controlled coating operation must meet the 
operating limits and work practice standards required in Secs. 63.4892

[[Page 449]]

and 63.4893, respectively. You must meet all the requirements of this 
section to demonstrate initial compliance with the emission limitations. 
When calculating the organic HAP emission rate according to this 
section, do not include any coatings, thinners, or cleaning materials 
used on coating operations for which you use the compliant material 
option or the emission rate without add-on controls option.
    (b) Compliance with operating limits. Except as provided in 
Sec. 63.4960(a)(4), you must establish and demonstrate continuous 
compliance during the initial compliance period with the operating 
limits required by Sec. 63.4892, using the procedures specified in 
Secs. 63.4966 and 63.4967.
    (c) Compliance with work practice requirements. You must develop, 
implement, and document your implementation of the work practice plan 
required by Sec. 63.4893 during the initial compliance period, as 
specified in Sec. 63.4930.
    (d) Compliance with emission limits. You must follow the procedures 
in paragraphs (e) through (m) of this section to demonstrate compliance 
with the applicable emission limit in Sec. 63.4890.
    (e) Determine the mass fraction of organic HAP, density, volume 
used, and volume fraction of coating solids. Follow the procedures 
specified in Sec. 63.4951(a) through (d) to determine the mass fraction 
of organic HAP, density, and volume of each coating, thinner, and 
cleaning material used during each compliance period and the volume 
fraction of coating solids for each coating used during each compliance 
period.
    (f) Calculate the total mass of organic HAP emissions before add-on 
controls. Using Equation 1 of Sec. 63.4951, calculate the total mass of 
organic HAP emissions before add-on controls from all coatings, 
thinners, and cleaning materials used during the compliance period.
    (g) Calculate the organic HAP emission reduction for each controlled 
coating operation. Determine the mass of organic HAP emissions reduced 
for each controlled coating operation during each compliance period. The 
emission reduction determination quantifies the total organic HAP 
emissions that pass through the emission capture system and are 
destroyed or removed by the add-on control device. Use the procedures in 
paragraph (h) of this section to calculate the mass of organic HAP 
emission reduction for each controlled coating operation using an 
emission capture system and add-on control device other than a solvent 
recovery system for which you conduct liquid-liquid material balances. 
For each controlled coating operation using a solvent recovery system 
for which you conduct a liquid-liquid material balance, use the 
procedures in paragraph (j) of this section to calculate the organic HAP 
emission reduction.
    (h) Calculate the organic HAP emission reduction for controlled 
coating operations not using liquid-liquid material balance. For each 
controlled coating operation using an emission capture system and add-on 
control device other than a solvent recovery system for which you 
conduct liquid-liquid material balances, calculate the organic HAP 
emission reduction, using Equation 1 of this section. The calculation 
applies the emission capture system efficiency and add-on control device 
efficiency to the mass of organic HAP contained in the coatings, 
thinners, and cleaning materials that are used in the coating operation 
served by the emission capture system and add-on control device during 
the compliance period. For any period of time a deviation specified in 
Sec. 63.4962(c) or (d) occurs in the controlled coating operation, 
including a deviation during a period of startup, shutdown, or 
malfunction, you must assume zero efficiency for the emission capture 
system and add-on control device. Equation 1 of this section treats the 
materials used during such a deviation as if they were used on an 
uncontrolled coating operation for the time period of the deviation:

    (m) Compliance demonstration. To demonstrate initial compliance with 
the emission limit during the compliance period as calculated using 
Equation 4 of this section, the HAP emission rate for the compliance 
period must be less than or equal to the applicable emission limit in 
Sec. 63.4890. You must keep all records as required by Secs. 63.4930 and 
63.4931. As part of the Notification of Compliance Status required by 
Sec. 63.4910 and the semiannual compliance reports required in 
Sec. 63.4920, you must identify the coating operation or group of 
coating operations for which you used the emission rate with add-on 
controls option. If there were no deviations from the emission limit, 
include a statement that the coating operation or group of coating 
operations was in compliance with the emission limitations during the 
initial compliance period because the organic HAP emission rate was less 
than or equal to the applicable emission limit in Sec. 63.4890, and you 
achieved the operating limits required by Sec. 63.4892 and the work 
practice standards required by Sec. 63.4893.



Sec. 63.4962  How do I demonstrate continuous compliance with the emission limitations?

    (a) Following the initial compliance period, you must complete a 
compliance demonstration according to the requirements in 
Sec. 63.4961(m) for each subsequent compliance period. Each month 
following the initial compliance period described in Sec. 63.4960 is a 
compliance period.
    (b) If the organic HAP emission rate for any compliance period 
exceeded the applicable emission limit in Sec. 63.4890, this is a 
deviation from the emission limitation for that compliance period and 
must be reported as specified in Secs. 63.4910(c)(6) and 63.4920(a)(7).
    (c) You must demonstrate continuous compliance with each operating 
limit required by Sec. 63.4892 that applies to you, as specified in 
Table 1 to this subpart.
    (1) If an operating parameter is out of the allowed range specified 
in Table 1 to this subpart, this is a deviation from the operating limit 
that must be reported as specified in Secs. 63.4910(c)(6) and 
63.4920(a)(7).
    (2) If an operating parameter deviates from the operating limit 
specified in Table 1 to this subpart, then you must

[[Page 455]]

assume that the emission capture system and add-on control device were 
achieving zero efficiency during the time period of the deviation. For 
the purposes of completing the compliance calculations specified in 
Sec. 63.4961, you must treat the materials used during a deviation on a 
controlled coating operation as if they were used on an uncontrolled 
coating operation for the time period of the deviation, as indicated in 
Equation 1 of Sec. 63.4961.
    (d) You must meet the requirements for bypass lines in 
Sec. 63.4967(b) for controlled coating operations for which you do not 
conduct liquid-liquid material balances. If any bypass line is opened 
and emissions are diverted to the atmosphere when the coating operation 
is running, this is a deviation that must be reported as specified in 
Secs. 63.4910(c)(6) and 63.4920(a)(7). For the purposes of completing 
the compliance calculations in Sec. 63.4961, you must treat the 
materials used during a deviation on a controlled coating operation as 
if they were used on an uncontrolled coating operation for the time 
period of the deviation, as indicated in Equation 1 of Sec. 63.4961.
    (e) You must demonstrate continuous compliance with the work 
practice standards in Sec. 63.4893. If you did not develop a work 
practice plan, or you did not implement the plan, or you did not keep 
the records required by Sec. 63.4930(k)(8), this is a deviation from the 
work practice standards that must be reported as specified in 
Secs. 63.4910(c)(6) and 63.4920(a)(7).
    (f) As part of each semiannual compliance report required in 
Sec. 63.4920, you must identify the coating operation or group of 
coating operations for which you used the emission rate with add-on 
controls option. If there were no deviations from the emission 
limitations, submit an affirmative statement that you were in compliance 
with the emission limitations during the reporting period because the 
organic HAP emission rate for each compliance period was less than or 
equal to the applicable emission limit in Sec. 63.4890, and you achieved 
the operating limits required by Sec. 63.4892 and the work practice 
standards required by Sec. 63.4893 during each compliance period.
    (g) During periods of startup, shutdown, or malfunction of the 
emission capture system, add-on control device, or coating operation 
that may affect emission capture or control device efficiency, you must 
operate in accordance with the SSMP required by Sec. 63.4900(c).
    (h) [Reserved]
    (i) You must maintain records as specified in Secs. 63.4930 and 
63.4931.



Sec. 63.4963  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.4960 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative coating operation operating conditions. You must 
conduct the performance test under representative operating conditions 
for the coating operation. Operations during periods of startup, 
shutdown, or malfunction, and during periods of nonoperation do not 
constitute representative conditions. You must record the process 
information that is necessary to document operating conditions during 
the test and explain why the conditions represent normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.4964. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.4965.
    (c) The performance test to determine add-on control device organic 
HAP destruction or removal efficiency must consist of three runs as 
specified

[[Page 456]]

in Sec. 63.7(e)(3) and each run must last at least 1 hour.



Sec. 63.4964  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.4960.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both of the conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a PTE and directs all the exhaust gases from the 
enclosure to an add-on control device.
    (2) All coatings, thinners, and cleaning materials used in the 
coating operation are applied within the capture system; coating solvent 
flash-off and coating, curing, and drying occurs within the capture 
system; and the removal of or evaporation of cleaning materials from the 
surfaces they are applied to occurs within the capture system. For 
example, this criterion is not met if parts enter the open shop 
environment when being moved between a spray booth and a curing oven.
    (b) Measuring capture efficiency. If the capture system does not 
meet both of the criteria in paragraphs (a)(1) and (2) of this section, 
then you must use one of the three protocols described in paragraphs 
(c), (d), and (e) of this section to measure capture efficiency. The 
capture efficiency measurements use TVH capture efficiency as a 
surrogate for organic HAP capture efficiency. For the protocols in 
paragraphs (c) and (d) of this section, the capture efficiency 
measurement must consist of three test runs. Each test run must be at 
least 3 hours duration or the length of a production run, whichever is 
longer, up to 8 hours. For the purposes of this test, a production run 
means the time required for a single part to go from the beginning to 
the end of production, which includes surface preparation activities and 
drying or curing time.
    (c) Liquid-to-uncaptured-gas protocol using a temporary total 
enclosure or building enclosure. The liquid-to-uncaptured-gas protocol 
compares the mass of liquid TVH in materials used in the coating 
operation to the mass of TVH emissions not captured by the emission 
capture system. Use a temporary total enclosure or a building enclosure 
and the procedures in paragraphs (c)(1) through (6) of this section to 
measure emission capture system efficiency using the liquid-to-
uncaptured-gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions for routing to an add-on control device, such as the entrance 
and exit areas of an oven or spray booth, must also be inside the 
enclosure. The enclosure must meet the applicable definition of a 
temporary total enclosure or building enclosure in Method 204 of 
appendix M to 40 CFR part 51.
    (2) Use Method 204A or 204F of appendix M to 40 CFR part 51 to 
determine the mass fraction, kg TVH per kg material, of TVH liquid input 
from each coating, thinner, and cleaning material used in the coating 
operation during each capture efficiency test run. To make the 
determination, substitute TVH for each occurrence of the term VOC in the 
methods.
    (3) Use Equation 1 of this section to calculate the mass of TVH 
liquid input from all the coatings, thinners, and cleaning materials 
used in the coating operation during each capture efficiency test run:
[GRAPHIC] [TIFF OMITTED] TR23MY03.038

Where:
TVHused = Mass of liquid total volatile hydrocarbons in 
materials used in the coating operation during the capture efficiency 
test run, lb.
TVHi = Mass fraction of TVH in coating, thinner, or cleaning 
material, i, that is used in the coating operation during the capture 
efficiency test run, kg TVH per kg material.

[[Page 457]]

Voli = Total volume of coating, thinner, or cleaning 
material, i, used in the coating operation during the capture efficiency 
test run, liters.
Di = Density of coating, thinner, or cleaning material, i, kg 
material per liter material.
n = Number of different coatings, thinners, and cleaning materials used 
in the coating operation during the capture efficiency test run.

    (4) Use Method 204D or E of appendix M to 40 CFR part 51 to measure 
the total mass of TVH emissions that are not captured by the emission 
capture system; they are measured as they exit the temporary total 
enclosure or building enclosure during each capture efficiency test run. 
To make the measurement, substitute TVH for each occurrence of the term 
VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (5) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.039

Where:
CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHused = Total mass of TVH liquid input used in the coating 
operation during the capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (6) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (d) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (d)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the coating operation where coatings, thinners, and cleaning materials 
are applied, and all areas where emissions from these applied coatings 
and materials subsequently occur, such as flash-off, curing, and drying 
areas. The areas of the coating operation where capture devices collect 
emissions generated by the coating operation for routing to an add-on 
control device, such as the entrance and exit areas of an oven or a 
spray booth, must also be inside the enclosure. The enclosure must meet 
the applicable definition of a temporary total enclosure or building 
enclosure in Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass of TVH emissions captured by the emission capture 
system during each capture efficiency test run as measured at the inlet 
to the add-on control device. To make the measurement, substitute TVH 
for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C measurement must 
be upstream from the add-on control device and must represent total 
emissions routed from the capture system and entering the add-on control 
device.

[[Page 458]]

    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass of TVH emissions that are not captured by the 
emission capture system; they are measured as they exit the temporary 
total enclosure or building enclosure during each capture efficiency 
test run. To make the measurement, substitute TVH for each occurrence of 
the term VOC in the methods.
    (i) Use Method 204D if the enclosure is a temporary total enclosure.
    (ii) Use Method 204E if the enclosure is a building enclosure. 
During the capture efficiency measurement, all organic compound emitting 
operations inside the building enclosure, other than the coating 
operation for which capture efficiency is being determined, must be shut 
down, but all fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system, using Equation 3 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.040

Where:
CE = Capture efficiency of the emission capture system vented to the 
add-on control device, percent.
TVHcaptured = Total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, kg.
TVHuncaptured = Total mass of TVH that is not captured by the 
emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg.

    (5) Determine the capture efficiency of the emission capture system 
as the average of the capture efficiencies measured in the three test 
runs.
    (e) Alternative capture efficiency protocol. As an alternative to 
the procedures specified in paragraphs (c) and (d) of this section, you 
may determine capture efficiency using any other capture efficiency 
protocol and test methods that satisfy the criteria of either the DQO or 
LCL approach as described in appendix A to subpart KK of this part.



Sec. 63.4965  How do I determine the add-on control device emission destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.4960. You 
must conduct three test runs as specified in Sec. 63.7(e)(3), and each 
test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. You may 
also use as an alternative to Method 3B, the manual method for measuring 
the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas 
in ANSI/ASME PTC

[[Page 459]]

19.10-1981, ``Flue and Exhaust Gas Analyses [Part 10, Instruments and 
Apparatus]'' (incorporated by reference, see Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60 to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be more 
than 50 parts per million (ppm) at the control device outlet.
    (2) Use Method 25A if the add-on control device is an oxidizer and 
you expect the total gaseous organic concentration as carbon to be 50 
ppm or less at the control device outlet.
    (3) Use Method 25A if the add-on control device is not an oxidizer.
    (c) If two or more add-on control devices are used for the same 
emission stream, then you must measure emissions at the outlet of each 
device. For example, if one add-on control device is a concentrator with 
an outlet for the high-volume, dilute stream that has been treated by 
the concentrator, and a second add-on control device is an oxidizer with 
an outlet for the low-volume, concentrated stream that is treated with 
the oxidizer, you must measure emissions at the outlet of the oxidizer 
and the high volume dilute stream outlet of the concentrator.
    (d) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR23MY03.041

Where:
Mf= Total gaseous organic emissions mass flow rate, kg/per 
hour (h).
Qsd= Volumetric flow rate of gases entering or exiting the 
add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, 
dry standard cubic meters/hour (dscm/h).
Cc= Concentration of organic compounds as carbon in the vent 
gas, as determined by Method 25 or Method 25A, parts per million by 
volume (ppmv), dry basis.
0.0416 = Conversion factor for molar volume, kg-moles per cubic meter 
(mol/m3) (@ 293 Kelvin (K) and 760 millimeters of mercury 
(mmHg)).

    (e) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR23MY03.042

Where:
DRE = Organic emissions destruction or removal efficiency of the add-on 
control device, percent.
Mfi= Total gaseous organic emissions mass flow rate at the 
inlet(s) to the add-on control device, using Equation 1 of this section, 
kg/h.
Mfo= Total gaseous organic emissions mass flow rate at the 
outlet(s) of the add-on control device, using Equation 1 of this 
section, kg/h.

    (f) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.4966  How do I establish the emission capture system and add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.4960 and described 
in Secs. 63.4963, 63.4964, and 63.4965, you must establish

[[Page 460]]

the operating limits required by Sec. 63.4892 according to this section, 
unless you have received approval for alternative monitoring and 
operating limits under Sec. 63.8(f) as specified in Sec. 63.4892.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must replace the catalyst bed or take corrective 
action consistent with the manufacturer's recommendations and conduct a 
new performance test to determine destruction efficiency according to 
Sec. 63.4965.
    (c) Carbon adsorbers. If your add-on control device is a carbon 
adsorber, establish the operating limits according to paragraphs (c)(1) 
and (2) of this section.
    (1) You must monitor and record the total regeneration desorbing gas 
(e.g., steam or nitrogen) mass flow for each regeneration cycle, and the 
carbon bed temperature after each carbon bed regeneration and cooling 
cycle, for the regeneration cycle either immediately preceding or 
immediately following the performance test.
    (2) The operating limits for your carbon adsorber are the minimum 
total desorbing gas mass flow recorded during the regeneration cycle and 
the maximum carbon bed temperature recorded after the cooling cycle.

[[Page 461]]

    (d) Condensers. If your add-on control device is a condenser, 
establish the operating limits according to paragraphs (d)(1) and (2) of 
this section.
    (1) During the performance test, you must monitor and record the 
condenser outlet (product side) gas temperature at least once every 15 
minutes during each of the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average condenser outlet (product side) gas temperature 
maintained during the performance test. This average condenser outlet 
gas temperature is the maximum operating limit for your condenser.
    (e) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.4964(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (e)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 1 to this subpart.
    (1) During the capture efficiency determination required by 
Sec. 63.4960 and described in Secs. 63.4963 and 63.4964, you must 
monitor and record either the gas volumetric flow rate or the duct 
static pressure for each separate capture device in your emission 
capture system at least once every 15 minutes during each of the three 
test runs at a point in the duct between the capture device and the add-
on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.
    (f) Concentrators. If your add-on control device includes a 
concentrator, you must establish operating limits for the concentrator 
according to paragraphs (f)(1) through (4) of this section.
    (1) During the performance test, you must monitor and record the 
desorption concentrate stream gas temperature at least once every 15 
minutes during each of the three runs of the performance test.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature. This is the minimum operating limit 
for the desorption concentrate gas stream temperature.
    (3) During the performance test, you must monitor and record the 
pressure drop of the dilute stream across the concentrator at least once 
every 15 minutes during each of the three runs of the performance test.
    (4) Use the data collected during the performance test to calculate 
and record the average pressure drop. This is the maximum operating 
limit for the dilute stream across the concentrator.
    (g) Bioreactors. If you are using a bioreactor, you must comply with 
the provisions for the use of an alternative monitoring method as set 
forth in 40 CFR 63.8(f).



Sec. 63.4967  What are the requirements for continuous parameter monitoring system installation, operation, and maintenance?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c), (e), and (f) of this section according to 
paragraphs (a)(1) through (6) of this section. You must install, 
operate, and maintain each CPMS specified in paragraphs (b) and (d) of 
this section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
3-hour period of the emission capture system and add-on control device 
operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that a controlled 
coating operation is operating, except during monitoring malfunctions, 
repairs to correct the monitor malfunctions, and required quality 
assurance or control

[[Page 462]]

activities (including, if applicable, calibration checks and required 
zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, repairs 
to correct the monitor malfunctions, out-of-control periods, or required 
quality assurance or control activities when calculating data averages. 
You must use all the data collected during all other periods in 
calculating the data averages for determining compliance with the 
emission capture system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coating operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the coating operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the coating operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.4920.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device 
(including those used with concentrators or with carbon adsorbers to 
treat desorbed concentrate streams), you must comply with the 
requirements in paragraphs (c)(1) through (3) of this section:
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, install a gas temperature monitor in 
the gas stream immediately before the catalyst bed, and if you are 
establishing operating limits according to

[[Page 463]]

Sec. 63.4966(b)(1) and (2), also install a gas temperature monitor in 
the gas stream immediately after the catalyst bed.
    (3) For each gas temperature monitoring device, you must meet the 
requirements in paragraphs (a) and (c)(3)(i) through (vi) of this 
section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.

Sec. 63.4981  What definitions apply to this subpart?

    Terms used in this subpart are defined in the CAA, in 40 CFR 63.2, 
and in this section as follows:
    Add-on control means an air pollution control device such as a 
thermal oxidizer or carbon adsorber that reduces pollution in an air 
stream by destruction or removal before discharge to the atmosphere.
    Adhesive means any chemical substance that is applied for the 
purpose of bonding two surfaces together.
    Capture device means a hood, enclosure, room, floor sweep, or other 
means of containing or collecting emissions and directing those 
emissions into an add-on air pollution control device.
    Capture efficiency or capture system efficiency means the portion 
(expressed as a percentage) of the pollutants from an emission source 
that is delivered to an add-on control device.

[[Page 465]]

    Capture system means one or more capture devices intended to collect 
emissions generated by a coating operation in the use of coatings or 
cleaning materials, both at the point of application and at subsequent 
points where emissions from the coatings and cleaning materials occur, 
such as flashoff, drying, or curing. As used in this subpart, multiple 
capture devices that collect emissions generated by a coating operation 
are considered a single capture system.
    Cleaning material means a solvent used to remove contaminants and 
other materials, such as dirt, grease, oil, and dried or wet coating 
(e.g., depainting), from a substrate before or after coating application 
or from equipment associated with a coating operation, such as spray 
booths, spray guns, racks, tanks, and hangers. Thus, it includes any 
cleaning material used on substrates or equipment or both.
    Coating means a material applied to a substrate for decorative, 
protective, or functional purposes. Such materials include, but are not 
limited to, paints, sealants, caulks, inks, adhesives, and maskants. 
Decorative, protective, or functional materials that consist only of 
protective oils for metal, acids, bases, or any combination of these 
substances are not considered coatings for the purposes of this subpart.
    Coating operation means equipment used to apply cleaning materials 
to a substrate to prepare it for coating application or to remove dried 
or wet coating (surface preparation); to apply coating to a substrate 
(coating application) and to dry or cure the coating after application; 
and to clean coating operation equipment (equipment cleaning). A single 
coating operation may include any combination of these types of 
equipment, but always includes at least the point at which a coating or 
cleaning material is applied and all subsequent points in the affected 
source where organic HAP emissions from that coating or cleaning 
material occur. There may be multiple coating operations in an affected 
source. Coating application with hand-held nonrefillable aerosol 
containers, touchup markers, or marking pens is not a coating operation 
for the purposes of this subpart.
    Coating solids means the nonvolatile portion of the coating that 
makes up the dry film.
    Continuous parameter monitoring system (CPMS) means the total 
equipment that may be required to meet the data acquisition and 
availability requirements of this subpart, used to sample, condition (if 
applicable), analyze, and provide a record of coating operation, or 
capture system, or add-on control device parameters.
    Controlled coating operation means a coating operation from which 
some or all of the organic HAP emissions are routed through an emission 
capture system and add-on control device.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limit, or operating 
limit, or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limit, or operating limit, or work 
practice standard in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is allowed by 
this subpart.
    Emission limitation means an emission limit, operating limit, or 
work practice standard.
    Enclosure means a structure that surrounds a source of emissions and 
captures and directs the emissions to an add-on control device.
    Exempt compound means a specific compound that is not considered a 
VOC due to negligible photochemical reactivity. The exempt compounds are 
listed in 40 CFR 51.100(s).
    Facility maintenance means the routine repair or renovation 
(including surface coating) of the tools, equipment, machinery, and 
structures that comprise the infrastructure of the affected facility and 
that are necessary for the facility to function in its intended 
capacity.

[[Page 466]]

    Manufacturer's formulation data means data on a material (such as a 
coating) that are supplied by the material manufacturer based on 
knowledge of the ingredients used to manufacture that material, rather 
than based on testing of the material with the test methods specified in 
Sec. 63.4941(a)(1) through (3). Manufacturer's formulation data may 
include, but are not limited to, information on density, organic HAP 
content, volatile organic matter content, and coating solids content.

HAP to the mass of a material in which it is contained, expressed as kg 
of organic HAP per kg of material.
    Month means a calendar month or a pre-specified period of 28 days to 
35 days to allow for flexibility in recordkeeping when data are based on 
a business accounting period.
    Organic HAP content means the mass of organic HAP per volume of 
coating solids for a coating, calculated using Equation 2 of 
Sec. 63.4941. The organic HAP content is determined for the coating in 
the condition it is in when received from its manufacturer or supplier 
and does not account for any alteration after receipt.
    Permanent total enclosure (PTE) means a permanently installed 
enclosure that meets the criteria of Method 204 of appendix M, 40 CFR 
part 51, for a PTE and that directs all the exhaust gases from the 
enclosure to an add-on control device.

for the purpose of providing lubrication or protection from corrosion 
without forming a solid film. This definition of protective oil 
includes, but is not limited to, lubricating oils, evaporative oils 
(including those that evaporate completely), and extrusion oils.
    Research or laboratory facility means a facility whose primary 
purpose is for research and development of new processes and products, 
that is conducted under the close supervision of technically trained 
personnel, and is not engaged in the manufacture of final or 
intermediate products for commercial purposes, except in a de minimis 
manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Startup, initial means the first time equipment is brought online in 
a facility.
    Surface preparation means use of a cleaning material on a portion of 
or all of a substrate. This includes use of a cleaning material to 
remove dried coating, which is sometimes called ``depainting'' or 
``paint stripping,'' for the purpose of preparing a substrate for 
coating application.
    Temporary total enclosure means an enclosure constructed for the 
purpose of measuring the capture efficiency of pollutants emitted from a 
given source as defined in Method 204 of appendix M, 40 CFR part 51.
    Thinner means an organic solvent that is added to a coating after 
the coating is received from the supplier.
    Total volatile hydrocarbon (TVH) means the total amount of 
nonaqueous volatile organic matter determined according to Methods 204 
and 204A through 204F of appendix M to 40 CFR part 51 and substituting 
the term TVH each place in the methods where the term VOC is used. The 
TVH includes both VOC and non-VOC.
    Uncontrolled coating operation means a coating operation from which 
none of the organic HAP emissions are routed through an emission capture 
system and add-on control device.
    Volatile organic compound (VOC) means any compound defined as VOC in 
40 CFR 51.100(s).
    Volume fraction of coating solids means the ratio of the volume of 
coating solids (also known as volume of nonvolatiles) to the volume of 
coating, expressed as liters of coating solids per liter of coating.
    Wastewater means water that is generated in a coating operation and 
is collected, stored, or treated prior to being discarded or discharged.

Subpart SSSS--National Emission Standards for Hazardous Air Pollutants: 
                      Surface Coating of Metal Coil

    Source: 67 FR 39812, June 10, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5080  What is in this subpart?

    This subpart describes the actions you must take to reduce emissions 
of hazardous air pollutants (HAP) if you own or operate a facility that 
performs metal coil surface coating operations and is a major source of 
HAP. This subpart establishes emission standards and states what you 
must do to comply. Certain requirements apply to all who must comply 
with the subpart; others depend on the means you use to comply with an 
emission standard.



Sec. 63.5090  Does this subpart apply to me?

    (a) The provisions of this subpart apply to each facility that is a 
major source of HAP, as defined in Sec. 63.2, at which a coil coating 
line is operated, except as provided in paragraph (b) of this section.
    (b) This subpart does not apply to any coil coating line that meets 
the criteria of paragraph (b)(1) or (2) of this section.
    (1) A coil coating line that is part of research or laboratory 
equipment.
    (2) A coil coating line on which at least 85 percent of the metal 
coil coated, based on surface area, is less than 0.15 millimeter (0.006 
inch) thick, except as provided in paragraph (c) of this section.
    (c) If you operate a coating line subject to subpart JJJJ of this 
part that also meets the criteria in either paragraph (c)(1) or (2) of 
this section, and you choose to comply with the requirements of this 
subpart, then such compliance constitutes compliance with subpart JJJJ. 
The coating line for which you choose this option is, therefore, 
included in the affected source for this subpart as defined in 
Sec. 63.5110 and shall not be included in the affected source for 
subpart JJJJ as defined in Sec. 63.3300.
    (1) The coating line is used to coat metal coil of thicknesses both 
less than and greater than or equal to 0.15 millimeter (0.006 inch) 
thick, regardless of the percentage of surface area of each thickness 
coated.
    (2) The coating line is used to coat only metal coil that is less 
than 0.15 millimeter (0.006 inch) thick and the coating line is 
controlled by a common control device that also receives organic HAP 
emissions from a coil coating line that is subject to the requirements 
of this subpart.

of this subpart because it meets the criteria in paragraph (b)(2) of 
this section, that for any rolling 12-month period fails to meet the 
criteria in paragraph (b)(2) would from that point forward become 
subject to the provisions of this subpart. After becoming subject to the 
provisions of this subpart, the coil coating line would no longer be 
eligible to use the criteria of paragraph (b)(2) of this section, even 
if in subsequent 12-month periods at least 85 percent of the metal coil 
coated, based on surface area, is less than 0.15 millimeter (0.006 inch)

Sec. 63.5150  If I use a control device to comply with the emission standards, what monitoring must I do?

 Table 1 to Sec.  63.5150--Control Device Monitoring Requirements Index
------------------------------------------------------------------------
If you operate a coil coating line
      and have the following:                  Then you must:
------------------------------------------------------------------------
1. Control device.................  Monitor control device operating
                                     parameters (Sec.  63.5150(a)(3)).
2. Capture system.................  Monitor capture system operating
                                     parameters (Sec.  63.5150(a)(4)).
3. Intermittently controllable      Monitor parameters related to
 work station.                       possible exhaust flow through any
                                     bypass to a control device (Sec.
                                     63.5150(a)(1)).
4. Continuous emission monitors...  Operate continuous emission monitors
                                     and perform a quarterly audit (Sec.
                                      63.5150(a)(2)).
------------------------------------------------------------------------

    (a) To demonstrate continuing compliance with the standards, you 
must monitor and inspect each capture system and each control device 
required to comply with Sec. 63.5120 following the date on which the 
initial performance test of the capture system and control device is 
completed. You must install and operate the monitoring equipment as 
specified in paragraphs (a)(1) through (4) of this section.
    (1) Bypass monitoring. If you operate coil coating lines with 
intermittently-controllable work stations, you must follow at least one 
of the procedures in paragraphs (a)(1)(i) through (iv) of this section 
for each curing oven associated with these work stations to monitor for 
potential bypass of the control device:
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate

[[Page 478]]

according to the manufacturer's specifications a flow control position 
indicator that provides a record indicating whether the exhaust stream 
from the curing oven is directed to the control device or is diverted 
from the control device. The time and flow control position must be 
recorded at least once per hour, as well as every time the flow 
direction is changed. The flow control position indicator must be 
installed at the entrance to any bypass line that could divert the 
exhaust stream away from the control device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration when the control device is in operation; a visual 
inspection of the seal or closure mechanism will be performed at least 
once every month to ensure that the valve or damper is maintained in the 
closed position, and the exhaust stream is not diverted through the 
bypass line.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve or damper is in the closed position through continuous 
monitoring of valve position when the control device is in operation. 
The monitoring system must be inspected at least once every month to 
verify that the monitor will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the coil coating line is stopped when flow is diverted away from 
the control device to any bypass line when the control device is in 
operation. The automatic shutdown system must be inspected at least once 
every month to verify that it will detect diversions of flow and shut 
down operations.
    (2) Continuous emission monitoring system (CEMS). If you are 
demonstrating continuous compliance with the standards in 
Sec. 63.5120(a)(1) or (2) through continuous emission monitoring of a 
control device, you must install, calibrate, operate, and maintain 
continuous emission monitors to measure the total organic volatile 
matter concentration at both the control device inlet and outlet, and 
you must continuously monitor flow rate. If you are demonstrating 
continuous compliance with the outlet organic HAP concentration limit in 
Sec. 63.5120(a)(3), you must install, calibrate, operate, and maintain a 
continuous emission monitor to measure the total organic volatile matter 
concentration at the control device outlet.
    (i) All CEMS must comply with performance specification 8 or 9 of 40 
CFR part 60, appendix B, as appropriate for the detection principle you 
choose. The requirements of 40 CFR part 60, procedure 1, appendix F must 
also be followed. In conducting the quarterly audits of the monitors as 
required by procedure 1, appendix F, you must use compounds 
representative of the gaseous emission stream being controlled.
    (ii) As specified in Sec. 63.8(c)(4)(ii), each CEMS and each flow 
rate monitor must complete a minimum of one cycle of operation 
(sampling, analyzing, and data recording) for each successive 15-minute 
period. Information which must be determined for recordkeeping purposes, 
as required by Sec. 63.5190(a)(1)(i) includes:
    (A) The hourly average of all recorded readings;
    (B) The daily average of all recorded readings for each operating 
day; and
    (C) The monthly average for each month during the semiannual 
reporting period.
    (3) Temperature monitoring of oxidizers. If you are complying with 
the requirements of the standards in Sec. 63.5120 through the use of an 
oxidizer and demonstrating continuous compliance through monitoring of 
an oxidizer operating parameter, you must comply with paragraphs 
(a)(3)(i) through (iii) of this section.
    (i) Install, calibrate, maintain, and operate temperature monitoring 
equipment according to manufacturer's specifications. The calibration of 
the chart recorder, data logger, or temperature indicator must be 
verified every 3 months; or the chart recorder, data logger, or 
temperature indicator must be replaced. You must replace the equipment 
either if you choose not to perform the calibration, or if the equipment 
cannot be calibrated properly. Each temperature monitoring device must 
be equipped with a continuous recorder. The device must have an

[[Page 479]]

accuracy of [plusmn]1 percent of the temperature being monitored in 
degrees Celsius, or [plusmn]1 [deg]Celsius, whichever is greater.
    (ii) For an oxidizer other than a catalytic oxidizer, to demonstrate 
continuous compliance with the operating limit established according to 
Sec. 63.5160(d)(3)(i), you must install the thermocouple or temperature 
sensor in the combustion chamber at a location in the combustion zone.
    (iii) For a catalytic oxidizer, if you are demonstrating continuous 
compliance with the operating limit established according to 
Sec. 63.5160(d)(3)(ii)(A) and (B), then you must install the 
thermocouples or temperature sensors in the vent stream at the nearest 
feasible point to the inlet and outlet of the catalyst bed. Calculate 
the temperature difference across the catalyst. If you are demonstrating 
continuous compliance with the operating limit established according to 
Sec. 63.5160(d)(3)(ii)(C) and (D), then you must install the 
thermocouple or temperature sensor in the vent stream at the nearest 
feasible point to the inlet of the catalyst bed.
    (4) Capture system monitoring. If you are complying with the 
requirements of the standards in Sec. 63.5120 through the use of a 
capture system and control device, you must develop a capture system 
monitoring plan containing the information specified in paragraphs 
(a)(4)(i) and (ii) of this section. You must monitor the capture system 
in accordance with paragraph (a)(4)(iii) of this section. You must make 
the monitoring plan available for inspection by the permitting authority 
upon request.
    (i) The monitoring plan must identify the operating parameter to be 
monitored to ensure that the capture efficiency measured during the 
initial compliance test is maintained, explain why this parameter is 
appropriate for demonstrating ongoing compliance, and identify the 
specific monitoring procedures.
    (ii) The plan also must specify operating limits at the capture 
system operating parameter value, or range of values, that demonstrates 
compliance with the standards in Sec. 63.5120. The operating limits must 
represent the conditions indicative of proper operation and maintenance 
of the capture system.
    (iii) You must conduct monitoring in accordance with the plan.
    (b) Any deviation from the required operating parameters which are 
monitored in accordance with paragraphs (a)(3) and (4) of this section, 
unless otherwise excused, will be considered a deviation from the 
operating limit.



Sec. 63.5160  What performance tests must I complete?

     Table 1 to Sec.  63.5160--Required Performance Testing Summary
------------------------------------------------------------------------
If you control HAP on your coil coating
                line by:                            You must:
------------------------------------------------------------------------

                                          efficiency of each control
                                          device according to Sec.
                                          63.5160(d), and (2) the
                                          capture efficiency of each
                                          capture system according to
                                          Sec.  63.5160(e).
------------------------------------------------------------------------

    (a) If you use a control device to comply with the requirements of 
Sec. 63.5120, you are not required to conduct a performance test to 
demonstrate compliance if one or more of the criteria in paragraphs 
(a)(1) through (3) of this section are met:
    (1) The control device is equipped with continuous emission monitors 
for determining total organic volatile matter concentration, and capture 
efficiency has been determined in accordance with the requirements of 
this subpart; and the continuous emission monitors are used to 
demonstrate continuous compliance in accordance with Sec. 63.5150(a)(2); 
or
    (2) You have received a waiver of performance testing under 
Sec. 63.7(h); or

[[Page 480]]

    (3) The control device is a solvent recovery system and you choose 
to comply by means of a monthly liquid-liquid material balance.
    (b) Organic HAP content. You must determine the organic HAP weight 
fraction of each coating material applied by following one of the 
procedures in paragraphs (b)(1) through (4) of this section:
    (1) Method 311. You may test the material in accordance with Method 
311 of appendix A of this part. The Method 311 determination may be 
performed by the manufacturer of the material and the results provided 
to you. The organic HAP content must be calculated according to the 
criteria and procedures in paragraphs (b)(1)(i) through (iii) of this 
section.
    (i) Count only those organic HAP that are measured to be present at 
greater than or equal to 0.1 weight percent for Occupational Safety and 
Health Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and greater than or equal to 1.0 weight percent for 
other organic HAP compounds.
    (ii) Express the weight fraction of each organic HAP you count 
according to paragraph (b)(1)(i) of this section as a value truncated to 
four places after the decimal point (for example, 0.3791).
    (iii) Calculate the total weight fraction of organic HAP in the 
tested material by summing the counted individual organic HAP weight 
fractions and truncating the result to three places after the decimal 
point (for example, 0.763).
    (2) Method 24. For coatings, you may determine the total volatile 
matter content as weight fraction of nonaqueous volatile matter and use 
it as a substitute for organic HAP, using Method 24 of 40 CFR part 60, 
appendix A. The Method 24 determination may be performed by the 
manufacturer of the coating and the results provided to you.
    (3) Alternative method. You may use an alternative test method for 
determining the organic HAP weight fraction once the Administrator has 
approved it. You must follow the procedure in Sec. 63.7(f) to submit an 
alternative test method for approval.
    (4) Formulation data. You may use formulation data provided that the 
information represents each organic HAP present at a level equal to or 
greater than 0.1 percent for OSHA-defined carcinogens as specified in 29 
CFR 1910.1200(d)(4) and equal to or greater than 1.0 percent for other 
organic HAP compounds in any raw material used, weighted by the mass 
fraction of each raw material used in the material. Formulation data may 
be provided to you by the manufacturer of the coating material. In the 
event of any inconsistency between test data obtained with the test 
methods specified in paragraphs (b)(1) through (3) of this section and 
formulation data, the test data will govern.
    (c) Solids content. You must determine the solids content of each 
coating material applied. You may determine the volume solids content 
using ASTM D2697-86 (Reapproved 1998) or ASTM D6093-97 (incorporated by 
reference, see Sec. 63.14), or an EPA approved alternative method. The 
ASTM D2697-86 (Reapproved 1998) or ASTM D6093-97 determination may be 
performed by the manufacturer of the material and the results provided 
to you. Alternatively, you may rely on formulation data provided by 
material providers to determine the volume solids.
    (d) Control device destruction or removal efficiency. If you are 
using an add-on control device, such as an oxidizer, to comply with the 
standard in Sec. 63.5120, you must conduct a performance test to 
establish the destruction or removal efficiency of the control device or 
the outlet HAP concentration achieved by the oxidizer, according to the 
methods and procedures in paragraphs (d)(1) and (2) of this section. 
During the performance test, you must establish the operating limits 
required by Sec. 63.5121 according to paragraph (d)(3) of this section.
    (1) An initial performance test to establish the destruction or 
removal efficiency of the control device must be conducted such that 
control device inlet and outlet testing is conducted simultaneously. To 
establish the outlet organic HAP concentration achieved by the oxidizer, 
only oxidizer outlet testing must be conducted. The data must be reduced 
in accordance with the

[[Page 481]]

test methods and procedures in paragraphs (d)(1)(i) through (ix).
    (i) Method 1 or 1A of 40 CFR part 60, appendix A, is used for sample 
and velocity traverses to determine sampling locations.
    (ii) Method 2, 2A, 2C, 2D, 2F, or 2G of 40 CFR part 60, appendix A, 
is used to determine gas volumetric flow rate.
    (iii) Method 3, 3A, or 3B of 40 CFR part 60, appendix A, used for 
gas analysis to determine dry molecular weight. You may also use as an 
alternative to Method 3B, the manual method for measuring the oxygen, 
carbon dioxide, and carbon monoxide content of exhaust gas, ANSI/ASME 
PTC 19.10-1981, ``Flue and Exhaust Gas Analyses'' (incorporated by 
reference, see Sec. 63.14).
    (iv) Method 4 of 40 CFR part 60, appendix A, is used to determine 
stack gas moisture.
    (v) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run, as specified in paragraph (d)(1)(vii) of this section.
    (vi) Method 25 or 25A of 40 CFR part 60, appendix A, is used to 
determine total gaseous non-methane organic matter concentration. Use 
the same test method for both the inlet and outlet measurements, which 
must be conducted simultaneously. You must submit notification of the 
intended test method to the Administrator for approval along with 
notification of the performance test required under Sec. 63.7 (b). You 
must use Method 25A if any of the conditions described in paragraphs 
(d)(1)(vi)(A) through (D) of this section apply to the control device.
    (A) The control device is not an oxidizer.
    (B) The control device is an oxidizer, but an exhaust gas volatile 
organic matter concentration of 50 ppmv or less is required to comply 
with the standards in Sec. 63.5120; or
    (C) The control device is an oxidizer, but the volatile organic 
matter concentration at the inlet to the control system and the required 
level of control are such that they result in exhaust gas volatile 
organic matter concentrations of 50 ppmv or less; or
    (D) The control device is an oxidizer, but because of the high 
efficiency of the control device, the anticipated volatile organic 
matter concentration at the control device exhaust is 50 ppmv or less, 
regardless of inlet concentration.
    (vii) Each performance test must consist of three separate runs, 
except as provided by Sec. 63.7(e)(3); each run must be conducted for at 
least 1 hour under the conditions that exist when the affected source is 
operating under normal operating conditions. For the purpose of 
determining volatile organic matter concentrations and mass flow rates, 
the average of the results of all runs will apply. If you are 
demonstrating initial compliance with the outlet organic HAP 
concentration limit in Sec. 63.5120(a)(3), only the average outlet 
volatile organic matter concentration must be determined.
    (viii) If you are determining the control device destruction or 
removal efficiency, for each run, determine the volatile organic matter 
mass flow rates using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.000

Where:
Mf=total organic volatile matter mass flow rate, kg/per hour 
          (h).
Cc=concentration of organic compounds as carbon in the vent 
          gas, as determined by Method 25 or Method 25A, ppmv, dry 
          basis.
Qsd=volumetric flow rate of gases entering or exiting the 
          control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 
          2G, dry standard cubic meters (dscm)/h.
0.0416=conversion factor for molar volume, kg-moles per cubic meter 
          (mol/m\3\) (@ 293 Kelvin (K) and 760 millimeters of mercury 
          (mmHg)).

    (ix) For each run, determine the control device destruction or 
removal efficiency, DRE, using Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.001


Where:

DRE=organic emissions destruction or removal efficiency of the add-on 
          control device, percent.
Mfi=organic volatile matter mass flow rate at the inlet to 
          the control device, kg/h.
Mfo=organic volatile matter mass flow rate at the outlet of 
          the control device, kg/h.


[[Page 482]]


    (x) The control device destruction or removal efficiency is 
determined as the average of the efficiencies determined in the three 
test runs and calculated in Equation 2 of this section.
    (2) You must record such process information as may be necessary to 
determine the conditions in existence at the time of the performance 
test. Operations during periods of start-up, shutdown, and malfunction 
will not constitute representative conditions for the purpose of a 
performance test.
    (3) Operating limits. If you are using a capture system and add-on 
control device other than a solvent recovery system for which you 
conduct a liquid-liquid material balance to comply with the requirements 
in Sec. 63.5120, you must establish the applicable operating limits 
required by Sec. 63.5121. These operating limits apply to each capture 
system and to each add-on emission control device that is not monitored 
by CEMS, and you must establish the operating limits during the 
performance test required by paragraph (d) of this section according to 
the requirements in paragraphs (d)(3)(i) through (iii) of this section.
    (i) Thermal oxidizer. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs 
(d)(3)(i)(A) and (B) of this section.
    (A) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (B) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (ii) Catalytic oxidizer. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (d)(3)(ii)(A) and (B) or paragraphs (d)(3)(ii)(C) and (D) of 
this section.
    (A) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (B) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (C) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(d)(3)(ii)(D) of this section. During the performance test, you must 
monitor and record the temperature just before the catalyst bed at least 
once every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (D) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (d)(3)(ii)(C) of this section. The plan must 
address, at a minimum, the elements specified in paragraphs 
(d)(3)(ii)(D)(1 (3) of this section.
    (1) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (2) Monthly inspection of the oxidizer system including the burner 
assembly and fuel supply lines for problems and,
    (3) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you must take corrective action consistent with the 
manufacturer's recommendations and conduct a new performance test to 
determine destruction efficiency according to Sec. 63.5160.
    (iii) Other types of control devices. If you use a control device 
other than an

[[Page 483]]

oxidizer or a solvent recovery system for which you choose to comply by 
means of a monthly liquid-liquid material balance, or wish to monitor an 
alternative parameter and comply with a different operating limit, you 
must apply to the Administrator for approval of alternative monitoring 
under Sec. 63.8(f).
    (e) Capture efficiency. If you are required to determine capture 
efficiency to meet the requirements of Sec. 63.5170(e)(2), (f)(1) 
through (2), (h)(2) through (4), or (i)(2) through (3), you must 
determine capture efficiency using the procedures in paragraph (e)(1), 
(2), or (3) of this section, as applicable.
    (1) For an enclosure that meets the criteria for a PTE, you may 
assume it achieves 100 percent capture efficiency. You must confirm that 
your capture system is a PTE by demonstrating that it meets the 
requirements of section 6 of EPA Method 204 of 40 CFR part 51, appendix 
M (or an EPA approved alternative method), and that all exhaust gases 
from the enclosure are delivered to a control device.
    (2) You may determine capture efficiency, CE, according to the 
protocols for testing with temporary total enclosures that are specified 
in Method 204A through F of 40 CFR part 51, appendix M. You may exclude 
never-controlled work stations from such capture efficiency 
determinations.
    (3) As an alternative to the procedures specified in paragraphs 
(e)(1) and (2) of this section, if you are required to conduct a capture 
efficiency test, you may use any capture efficiency protocol and test 
methods that satisfy the criteria of either the Data Quality Objective 
or the Lower Confidence Limit approach as described in appendix A to 
subpart KK of this part. You may exclude never-controlled work stations 
from such capture efficiency determinations.

                   Requirements for Showing Compliance



Sec. 63.5170  How do I demonstrate compliance with the standards?

    You must include all coating materials (as defined in Sec. 63.5110) 
used in the affected source when determining compliance with the 
applicable emission limit in Sec. 63.5120. To make this determination, 
you must use at least one of the four compliance options listed in Table 
1 of this section. You may apply any of the compliance options to an 
individual coil coating line, or to multiple lines as a group, or to the 
entire affected source. You may use different compliance options for 
different coil coating lines, or at different times on the same line. 
However, you may not use different compliance options at the same time 
on the same coil coating line. If you switch between compliance options 
for any coil coating line or group of lines, you must document this 
switch as required by Sec. 63.5190(a), and you must report it in the 
next semiannual compliance report required in Sec. 63.5180.

 devices and maintaining an          liter solids on a rolling 12-month
 acceptable equivalent emission      average as applied basis,
 rate.                               determined monthly. Paragraph (d)
                                     of this section.
------------------------------------------------------------------------

    (a) As-purchased compliant coatings. If you elect to use coatings 
that individually meet the organic HAP emission limit in 
Sec. 63.5120(a)(2) as-purchased, to which you will not add HAP during 
distribution or application, you must demonstrate that each coating 
material applied during the 12-month compliance period contains no more 
than 0.046 kg HAP per liter of solids on an as-purchased basis.
    (1) Determine the organic HAP content for each coating material in 
accordance with Sec. 63.5160(b) and the volume solids content in 
accordance with Sec. 63.5160(c).
    (2) Combine these results using Equation 1 of this section and 
compare the result to the organic HAP emission limit in 
Sec. 63.5120(a)(2) to demonstrate that each coating material contains no 
more organic HAP than the limit.

each coating material applied during the 12-month compliance period 
contains no more than 0.046 kg of organic HAP per liter of solids 
applied in accordance with (b)(1) of this section, or demonstrate that 
the average of all coating materials applied during the 12-month 
compliance period contain no more than 0.046 kg of organic HAP per liter 
of solids applied in accordance with paragraph (b)(2) of this section.
    (1) To demonstrate that the average organic HAP content on the basis 
of solids applied for each coating material applied, HSi yr, 
is less than 0.046 kg HAP per liter solids applied for the 12-month 
compliance period, use Equation 2 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.003

Where:

Hsi yr = average for the 12-month compliance period, as-
          applied, organic HAP to solids ratio of material, i, kg 
          organic HAP/liter solids applied.

    (2) To demonstrte that the average organic HAP content on the basis 
of solids applied, HS yr, of all coating materials applied is 
less than 0.046 kg HAP per liter solids applied for the 12-month 
compliance period, use Equation 3 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.004

Where:

HS yr = average for the 12-month compliance period, as-
          applied, organic HAP to solids ratio of all materials applied, 
          kg organic HAP/liter solids applied.

    (c) Capture and control to reduce emissions to no more than the 
allowable limit. If you use one or more capture systems and one or more 
control devices and demonstrate an average overall organic HAP control 
efficiency of at least 98 percent for each month to comply with 
Sec. 63.5120(a)(1); or operate a capture system and oxidizer so that the 
capture efficiency is 100 percent and the oxidizer outlet HAP 
concentration is no greater than 20 ppmv on a dry basis to comply with 
Sec. 63.5120(a)(3), you must follow one of the procedures in paragraphs 
(c)(1) through (4) of this section. Alternatively, you may demonstrate 
compliance for an individual coil coating line by operating its capture 
system and control device and continuous parameter monitoring system 
according to the procedures in paragraph (i) of this section.
    (1) If the affected source uses one compliance procedure to limit 
organic HAP emissions to the level specified in Sec. 63.5120(a)(1) or 
(2) and has only always-controlled work stations, then you must 
demonstrate compliance with the provisions of paragraph (e) of this 
section when emissions from the affected source are controlled by one or 
more solvent recovery devices.
    (2) If the affected source uses one compliance procedure to limit 
organic HAP emissions to the level specified in Sec. 63.5120(a)(1) or 
(2) and has only always-controlled work stations, then you must 
demonstrate compliance with the provisions of paragraph (f) of this 
section when emissions are controlled by one or more oxidizers.
    (3) If the affected source operates both solvent recovery and 
oxidizer control devices, one or more never-controlled work stations, or 
one or more intermittently-controllable work stations, or uses more than 
one compliance procedure, then you must demonstrate compliance with the 
provisions of paragraph (g) of this section.
    (4) The method of limiting organic HAP emissions to the level 
specified in Sec. 63.5120(a)(3) is the installation and operation of a 
PTE around each work station and associated curing oven in the coating 
line and the ventilation of all organic HAP emissions from each PTE

[[Page 486]]

to an oxidizer with an outlet organic HAP concentration of no greater 
than 20 ppmv on a dry basis. An enclosure that meets the requirements in 
Sec. 63.5160(e)(1) is considered a PTE. Initial compliance of the 
oxidizer with the outlet organic HAP concentration limit is demonstrated 
either through continuous emission monitoring according to paragraph 
(c)(4)(ii) of this section or through performance tests using the 
procedure in Sec. 63.5160(d). If this method is selected, you must meet 
the requirements of paragraph (c)(4)(i) of this section to demonstrate 
continuing achievement of 100 percent capture of organic HAP emissions 
and either paragraph (c)(4)(ii) or paragraph (c)(4)(iii) of this 
section, respectively, to demonstrate continuous compliance with the 
oxidizer outlet organic HAP concentration limit through continuous 
emission monitoring or continuous operating parameter monitoring:
    (i) Whenever a work station is operated, continuously monitor the 
capture system operating parameter established in accordance with 
Sec. 63.5150(a)(4).
    (ii) To demonstrate that the value of the exhaust gas organic HAP 
concentration at the outlet of the oxidizer is no greater than 20 ppmv, 
on a dry basis, install, calibrate, operate, and maintain CEMS according 
to the requirements of Sec. 63.5150(a)(2).
    (iii) To demonstrate continuous compliance with operating limits 
established in accordance with Sec. 63.5150(a)(3), whenever a work 
station is operated, continuously monitor the applicable oxidizer 
operating parameter.
    (d) Capture and control to achieve the emission rate limit. If you 
use one or more capture systems and one or more control devices and 
limit the organic HAP emission rate to no more than 0.046 kg organic HAP 
emitted per liter of solids applied on a 12-month average as-applied 
basis, then you must follow one of the procedures in paragraphs (d)(1) 
through (3) of this section.
    (1) If you use one or more solvent recovery devices, you must 
demonstrate compliance with the provisions in paragraph (e) of this 
section.
    (2) If you use one or more oxidizers, you must demonstrate 
compliance with the provisions in paragraph (f) of this section.
    (3) If you use both solvent recovery devices and oxidizers, or 
operate one or more never-controlled work stations or one or more 
intermittently controllable work stations, you must demonstrate 
compliance with the provisions in paragraph (g) of this section.
    (e) Use of solvent recovery to demonstrate compliance. If you use 
one or more solvent recovery devices to control emissions from always-
controlled work stations, you must show compliance by following the 
procedures in either paragraph (e)(1) or (2) of this section:
    (1) Liquid-liquid material balance. Perform a liquid-liquid material 
balance for each month as specified in paragraphs (e)(1)(i) through (vi) 
of this section and use Equations 4 through 6 of this section to convert 
the data to units of this standard. All determinations of quantity of 
coating and composition of coating must be made at a time and location 
in the process after all ingredients (including any dilution solvent) 
have been added to the coating, or appropriate adjustments must be made 
to account for any ingredients added after the amount of coating has 
been determined.
    (i) Measure the mass of each coating material applied on the work 
station or group of work stations controlled by one or more solvent 
recovery devices during the month.
    (ii) If demonstrating compliance with the organic HAP emission rate 
based on solids applied, determine the organic HAP content of each 
coating material applied during the month following the procedure in 
Sec. 63.5160(b).
    (iii) Determine the volatile matter content of each coating material 
applied during the month following the procedure in Sec. 63.5160(c).
    (iv) If demonstrating compliance with the organic HAP emission rate 
based on solids applied, determine the solids content of each coating 
material applied during the month following the procedure in 
Sec. 63.5160(c).
    (v) For each solvent recovery device used to comply with 
Sec. 63.5120(a), install, calibrate, maintain, and operate according to 
the manufacturer's specifications, a device that indicates the 
cumulative amount of volatile matter

[[Page 487]]

recovered by the solvent recovery device on a monthly basis. The device 
must be initially certified by the manufacturer to be accurate to within 
[plusmn] 2.0 percent.
    (vi) For each solvent recovery device used to comply with 
Sec. 63.5120(a), measure the amount of volatile matter recovered for the 
month.
    (vii) Recovery efficiency, Rv. Calculate the volatile 
organic matter collection and recovery efficiency, Rv, using 
Equation 4 of this section:
[GRAPHIC] [TIFF OMITTED] TR10JN02.005

Where:

          expressed as a weight fraction, kg/kg.
Mj = mass of solvent, thinner, reducer, diluent, or other 
          non-solids-containing coating material (excluding 
          H2O), j, applied in a month, kg.
p = number of different coating materials applied in a month.

 Subpart TTTT--National Emission Standards for Hazardous Air Pollutants 
                    for Leather Finishing Operations

    Source: 67 FR 9162, Feb. 27, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for leather finishing operations. These 
standards limit HAP emissions from specified leather finishing 
operations. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with the emission standards.



Sec. 63.5285  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a leather 
finishing operation that is a major source of hazardous air pollutants 
(HAP) emissions or that is located at, or is part of, a major source of 
HAP emissions. A leather finishing operation is defined in Sec. 63.5460. 
In general, a leather finishing operation is a single process or group 
of processes used to adjust and improve the physical and aesthetic 
characteristics of the leather surface

[[Page 500]]

through multistage application of a coating comprised of dyes, pigments, 
film-forming materials, and performance modifiers dissolved or suspended 
in liquid carriers.
    (b) You are a major source of HAP emissions if you own or operate a 
plant site that emits or has the potential to emit any single HAP at a 
rate of 10 tons (9.07 megagrams) or more per year or any combination of 
HAP at a rate of 25 tons (22.68 megagrams) or more per year.
    (c) You are not subject to this subpart if your source finishes 
leather solely for the purpose of research and development.



Sec. 63.5290  What parts of my facility does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at leather finishing operations.
    (b) The affected source subject to this subpart is the collection of 
all equipment and activities used for the multistage application of 
finishing materials to adjust and improve the physical and aesthetic 
characteristics of the leather surface. This subpart applies to the 
leather finishing operations listed in paragraphs (b)(1) through (4) of 
this section and as defined in Sec. 63.5460, whether or not the 
operations are collocated with leather tanning operations:
    (1) Upholstery leather with greater than or equal to 4 grams finish 
add-on per square foot of leather;
    (2) Upholstery leather with less than 4 grams finish add-on per 
square foot of leather;
    (3) Water-resistant/specialty leather; and
    (4) Nonwater-resistant leather.
    (c) An affected source does not include portions of your leather 
finishing operation that are listed in paragraphs (c)(1) and (2) of this 
section:
    (1) Equipment used solely with leather tanning operations; and
    (2) That portion of your leather finishing operation using a solvent 
degreasing process, such as in the manufacture of leather chamois, that 
is already subject to the Halogenated Solvent Cleaning NESHAP (40 CFR 
part 63, subpart T).
    (d) An affected source is a new affected source if you commenced 
construction of the affected source on or after October 2, 2000, and you 
meet the applicability criteria at the time you commenced construction.
    (e) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (f) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.5295  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section:
    (1) If you startup your affected source before February 27, 2002, 
then you must comply with the emission standards for new and 
reconstructed sources in this subpart no later than February 27, 2002.
    (2) If you startup your affected source after February 27, 2002, 
then you must comply with the emission standards for new and 
reconstructed sources in this subpart upon startup of your affected 
source.
    (b) If you have an existing affected source, you must comply with 
the emission standards for existing sources no later than February 28, 
2005.
    (c) If you have an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP and an 
affected source subject to this subpart, paragraphs (c)(1) and (2) of 
this section apply.
    (1) An area source that meets the criteria of a new affected source, 
as specified at Sec. 63.5290(d), or a reconstructed affected source, as 
specified at Sec. 63.5290(e), must be in compliance with this subpart 
upon becoming a major source.
    (2) An area source that meets the criteria of an existing affected 
source, as specified at Sec. 63.5290(f), must be in compliance with this 
subpart no later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec. 63.5415 and 
in subpart A of this part. Some of the notifications must be submitted 
before you are required to comply with the emission standards in this 
subpart.

[[Page 501]]

                                Standards



Sec. 63.5305  What emission standards must I meet?

    The emission standards limit the number of pounds of HAP lost per 
square foot of leather processed. You must meet each emission limit in 
Table 1 of this subpart that applies to you.

                         Compliance Requirements



Sec. 63.5320  How does my affected major source comply with the HAP emission standards?

    (a) All affected sources must be in compliance with the requirements 
of this subpart at all times, including periods of startup, shutdown, 
and malfunction.
    (b) 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).
    (c) You must perform all of the items listed in paragraphs (c)(1) 
through (10) of this section:
    (1) Submit the necessary notifications in accordance with 
Sec. 63.5415.
    (2) Develop and implement a plan for demonstrating compliance in 
accordance with Sec. 63.5325.
    (3) Submit the necessary reports in accordance with Sec. 63.5420.
    (4) Keep a finish inventory log, as specified at Sec. 63.5335(b), to 
record monthly the pounds of each type of finish applied for each 
leather product process operation and the mass fraction of HAP in each 
applied finish. You may be required to start recordkeeping prior to the 
compliance dates specified at Sec. 63.5295.
    (5) Keep an inventory log, as specified at Sec. 63.5430(f), to 
record monthly the surface area of leather processed in 1,000's of 
square feet for each product process operation. You may be required to 
start recordkeeping prior to the compliance dates specified at 
Sec. 63.5295.
    (6) Determine the actual HAP loss from your affected source in 
accordance with Sec. 63.5335.
    (7) Determine the allowable HAP loss for your affected source in 
accordance with Sec. 63.5340.
    (8) Determine the compliance ratio for your affected source each 
month as specified at Sec. 63.5330. The compliance ratio compares your 
actual HAP loss to your allowable HAP loss for the previous 12 months.
    (9) Maintain the compliance ratio for your affected source at or 
below 1.00 in accordance with Sec. 63.5330.
    (10) Maintain all the necessary records you have used to demonstrate 
compliance with this subpart in accordance with Sec. 63.5430.



Sec. 63.5325  What is a plan for demonstrating compliance and when must I have one in place?

    (a) You must develop and implement a written plan for demonstrating 
compliance that provides the detailed procedures you will follow to 
monitor and record data necessary for demonstrating compliance with this 
subpart. Procedures followed for quantifying HAP loss from the source 
and amount of leather processed vary from source to source because of 
site-specific factors such as equipment design characteristics and 
operating conditions. Typical procedures include one or more accurate 
measurement methods such as weigh scales and volumetric displacement. 
Because the industry does not have a uniform set of procedures, you must 
develop and implement your own site-specific plan for demonstrating 
compliance not later than the compliance date for your source. You must 
also incorporate the plan for demonstrating compliance by reference in 
the source's title V permit. The plan for demonstrating compliance must 
include the items listed in paragraphs (a)(1) through (7) of this 
section:
    (1) The name and address of the owner or operator.
    (2) The physical address of the leather finishing operation.
    (3) Provide a detailed description of all methods of measurement 
your source will use to determine your finish usage, HAP content of each 
finish, quantity of leather processed, and leather product process 
operation type.
    (4) Specify when each measurement will be made.
    (5) Provide examples of each calculation you will use to determine 
your compliance status. Include examples of how you will convert data 
measured

[[Page 502]]

with one parameter to other terms for use in compliance determination.
    (6) Provide example logs of how data will be recorded.
    (7) Provide a quality assurance/quality control plan to ensure that 
the data continue to meet compliance demonstration needs.
    (b) You may be required to revise your plan for demonstrating 
compliance. We may require reasonable revisions if the procedures lack 
detail, are inconsistent, or do not accurately determine finish usage, 
HAP content of each finish, quantity of leather processed, or leather 
product process operation type.



Sec. 63.5330  How do I determine the compliance ratio?

    (a) When your source has processed leather for 12 months, you must 
determine the compliance ratio for your affected source by the fifteenth 
of each month for the previous 12 months.
    (b) You must determine the compliance ratio using Equation 1 of this 
section as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.003

Where:

Actual HAP Loss = Pounds of actual HAP loss for the previous 12 months, 
as determined in Sec. 63.5335.
Allowable HAP Loss = Pounds of allowable HAP loss for the previous 12 
months, as determined in Sec. 63.5340.

    (1) If the value of the compliance ratio is less than or equal to 
1.00, your affected source was in compliance with the applicable HAP 
emission limits of this subpart for the previous month.
    (2) If the value of the compliance ratio is greater than 1.00, your 
affected source was deviating from compliance with the applicable HAP 
emission limits of this subpart for the previous month.



Sec. 63.5335  How do I determine the actual HAP loss?

    (a) This section describes the information and procedures you must 
use to determine the actual HAP loss from your leather finishing 
operation. By the fifteenth of each month, you must determine the actual 
HAP loss in pounds from your leather finishing operation for the 
previous month.
    (b) Use a finish inventory log to record the pounds of each type of 
finish applied for each leather product process operation and the mass 
fraction of HAP in each applied finish. Figure 1 of this subpart shows 
an example log for recording the minimum information necessary to 
determine your finish usage and HAP loss. The finish inventory log must 
contain, at a minimum, the information for each type of finish applied 
listed in paragraphs (b)(1) through (7) of this section:
    (1) Finish type.
    (2) Pounds (or density and volume) of each finish applied to the 
leather.
    (3) Mass fraction of HAP in each applied finish.
    (4) Date of the recorded entry.
    (5) Time of the recorded entry.
    (6) Name of the person recording the entry.
    (7) Product process operation type.
    (c) To determine the pounds of HAP loss for the previous month, you 
must first determine the pounds of HAP loss from each finish application 
according to paragraph (c)(1) or (2) of this section.
    (1) For facilities not using add-on emission control devices, the 
entire HAP content of the finishes are assumed to be released to the 
environment. Using the finish inventory log, multiply the pounds of each 
recorded finish usage by the corresponding mass fraction of HAP in the 
finish. The result is the HAP loss in pounds from each finish 
application. Sum the pounds of HAP loss from all finish applications 
recorded during the previous month to determine the total monthly

[[Page 503]]

HAP loss in pounds from your finishing operation.
    (2) For facilities using add-on emission control devices, the finish 
inventory log and the emission reduction efficiency of the add-on 
capture and control devices can be used to determine the net HAP loss in 
pounds. The emission reduction efficiency for a control device must be 
determined from a performance test conducted in accordance with 
Secs. 63.5375 and 63.5380. Using the finish inventory log, multiply the 
pounds of each recorded finish usage by the corresponding mass fraction 
of HAP in the finish. The result is the gross HAP loss in pounds from 
each finish application prior to the add-on control device. Multiply the 
gross HAP loss by the percent emission reduction achieved by the add-on 
control device and then subtract this amount from the gross HAP loss. 
The result is the net HAP loss in pounds from each finish application. 
Sum the pounds of net HAP loss from all finish applications recorded 
during the previous month to determine the total monthly net HAP loss in 
pounds from your finishing operation.
    (d) After collecting HAP loss data for 12 months, you must also 
determine by the fifteenth of each month the annual HAP loss in pounds 
by summing the monthly HAP losses for the previous 12 months. The annual 
HAP loss is the ``actual HAP loss,'' which is used in Equation 1 of 
Sec. 63.5330 to calculate your compliance ratio, as described in 
Sec. 63.5330.



Sec. 63.5340  How do I determine the allowable HAP loss?

    (a) By the fifteenth of each month, you must determine the allowable 
HAP loss in pounds from your leather finishing operation for the 
previous month.
    (b) To determine the allowable HAP loss for your leather finishing 
operation, you must select the appropriate HAP emission limit, expressed 
in pounds of HAP loss per 1,000 square feet of leather processed, from 
Table 1 of this subpart, for each type of leather product process 
operation performed during the previous 12 months. Under the appropriate 
existing or new source column, select the HAP emission limit that 
corresponds to each type of product process operation performed during 
the previous 12 months. Next, determine the annual total of leather 
processed in 1,000's of square feet for each product process operation 
in accordance with Sec. 63.5400. Then, multiply the annual total of 
leather processed in each product process operation by the corresponding 
HAP emission limit to determine the allowable HAP loss in pounds for the 
corresponding leather product process operation. Finally, sum the pounds 
of HAP loss from all leather product process operations performed in the 
previous 12 months. Equation 1 of this section illustrates the 
calculation of allowable HAP loss as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.004

Where:

Annual Total of Leather Processed = 1,000's of square feet of leather 
processed in the previous 12 months in product process operation ``i''.
HAP Emission Limit = From Table 1 of this subpart, the HAP emission 
limit in pounds of HAP loss per 1,000 square feet of leather processed 
for product process operation ``i''.
n = Number of leather product process operation types performed during 
the previous 12 months.

    (c) The resulting ``allowable HAP loss'' is used in Equation 1 of 
Sec. 63.5330 to calculate your compliance ratio, as described in 
Sec. 63.5330.

[[Page 504]]



Sec. 63.5345  How do I distinguish between the two upholstery product process operations?

    (a) Product process operations that finish leather for use in 
automobile and furniture seat coverings are categorized as an upholstery 
product process operation. There are two upholstery product process 
operations subject to the requirements of this subpart--operations with 
less than 4 grams of finish add-on per square foot, and operations with 
4 grams or more of finish add-on per square foot. You must distinguish 
between the two upholstery product process operations so that you can 
determine which HAP emission limit in Table 1 of this subpart applies to 
your affected source.
    (b) You must determine finish add-on by calculating the difference 
in mass before and after the finishing process. You may use an empirical 
method to determine the amount of finish add-on applied during the 
finishing process, as described in paragraphs (b)(1) through (4) of this 
section:
    (1) Weigh a one square foot representative section of polyester 
film, paper, cardstock, or equivalent material substrate to be finished. 
This will provide an initial mass and surface area prior to starting the 
finishing process.
    (2) Use a scale with an accuracy of at least 5 percent of the mass 
in grams of the representative section of substrate.
    (3) Upon completion of these measurements, process the 
representative section of substrate on the finishing line as you would 
for a typical section of leather.
    (4) After the finishing and drying process, weigh the representative 
section of substrate to determine the final mass. Divide the net mass in 
grams gained on the representative section by its surface area in square 
feet to determine grams per square foot of finish add-on. Equation 1 of 
this section illustrates this calculation, as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.005

Where:

Finish Add-On = Grams per square foot of finish add-on applied to a 
representative section of polyester film or equivalent material 
substrate.
Final Mass = Final mass in grams of representative section of polyester 
film or equivalent material substrate, after finishing and drying.
Initial Mass = Initial mass in grams of representative section of 
polyester film or equivalent material substrate, prior to finishing.
Surface Area = Surface area in square feet of a representative section 
of polyester film or equivalent material substrate.

    (c) Any appropriate engineering units may be used for determining 
the finish add-on. However, finish add-on results must be converted to 
the units of grams of finish add-on per square foot of leather 
processed. If multiple representative leather sections are analyzed, 
then use the average of these measurements for selecting the appropriate 
product process operation.



Sec. 63.5350  How do I distinguish between the water-resistant/specialty and nonwater-resistant leather product process operations?

    (a) Product process operations that finish leather for nonupholstery 
use are categorized as either water-resistant/specialty or nonwater-
resistant product process operations. You must distinguish between the 
water-resistant/specialty and nonwater-resistant product process 
operations so that you can determine which HAP emission limit in Table 1 
of this subpart applies to your affected source. Water-resistant and 
nonwater-resistant product process operations for nonupholstery use can 
be distinguished using the methods described in paragraph (b) of this 
section. Specialty leather product process operations for nonupholstery

[[Page 505]]

use can be distinguished using the criteria described in paragraph (c) 
of this section.
    (b) To determine whether your product process operation produces 
water-resistant or nonwater-resistant leather, you must conduct the 
Maeser Flexes test method according to American Society for Testing and 
Materials (ASTM) Designation D2099-00 (incorporated by reference-see 
Sec. 63.14) or a method approved by the Administrator.
    (1) Statistical analysis of initial water penetration data performed 
to support ASTM Designation D2099-00 indicates that poor quantitative 
precision is associated with this testing method. Therefore, at a 
minimum, 36 leather substrate samples (i.e., three sections of leather 
substrate from at least 12 sides of leather), must be tested to 
determine the water-resistant characteristics of the leather. You must 
average the results of these tests to determine the final number of 
Maeser Flexes prior to initial water penetration.
    (2) Results from leather samples indicating an average of 5,000 
Maeser Flexes or more is considered a water-resistant product process 
operation, and results indicating less than 5,000 Maeser Flexes is 
considered a nonwater-resistant product process operation. However, 
leather samples resulting in less than 5,000 Maeser Flexes may be 
categorized as specialty leather in paragraph (c) of this section.
    (c) To determine whether your product process operation produces 
specialty leather, you must meet the criteria in paragraphs (c)(1) and 
(2) of this section:
    (1) The leather must be a select grade of chrome tanned, bark 
retanned, or fat liquored leather.
    (2) The leather must be retanned through the application of greases, 
waxes, and oils in quantities greater than 25 percent of the dry leather 
weight. Specialty leather is also finished with higher solvent-based 
finishes that provide rich color, luster, or an oily/tacky feel. 
Specialty leather products may include, but not limited to, specialty 
shoe leather and top grade football leathers.



Sec. 63.5355  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) You must collect data at all required intervals as specified in 
your plan for demonstrating compliance as specified at Sec. 63.5325.
    (c) For emission control devices, except for monitor malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, as applicable, calibration checks and required zero and span 
adjustments), you must monitor continuously (or collect data at all 
required intervals) at all times that the affected source is operating.
    (d) 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, nor may such data be used in fulfilling a minimum data 
availability requirement, if applicable. You must use all the data 
collected during all other periods in assessing the compliance ratio, 
and, if an emission control device is used, in assessing the operation 
of the control device.



Sec. 63.5360  How do I demonstrate continuous compliance with the emission standards?

    (a) You must demonstrate continuous compliance with the emission 
standards in Sec. 63.5305 by following the requirements in paragraphs 
(a)(1) and (2) of this section:
    (1) You must collect and monitor data according to the procedures in 
your plan for demonstrating compliance as specified in Sec. 63.5325.
    (2) If you use an emission control device, you must collect the 
monitoring data according to 40 CFR part 63, subpart SS.
    (3) You must maintain your compliance ratio less than or equal to 
1.00, as specified at Sec. 63.5330.
    (b) You must report each instance in which you did not meet the 
emission

[[Page 506]]

standards in Sec. 63.5305. This includes periods of startup, shutdown, 
and malfunction. These deviations must be reported according to the 
requirements in Sec. 63.5420(b).
    (c) You must conduct the initial compliance demonstration before the 
compliance date that is specified for your source in Sec. 63.5295.

               Testing and Initial Compliance Requirements



Sec. 63.5375  When must I conduct a performance test or initial compliance demonstration?

    You must conduct performance tests after the installation of any 
emission control device that reduces HAP emissions and can be used to 
comply with the HAP emission requirements of this subpart. You must 
complete your performance tests not later than 60 calendar days before 
the end of the 12-month period used in the initial compliance 
determination.



Sec. 63.5380  How do I conduct performance tests?

    (a) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e) and the procedures of Sec. 63.997(e)(1) and 
(2).
    (b) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (c) You must conduct three separate test runs for each performance 
test required in this section, as specified in Sec. 63.7(e)(3). Each 
test run must last at least 1 hour.



Sec. 63.5385  How do I measure the quantity of finish applied to the leather?

    (a) To determine the amount of finish applied to the leather, you 
must measure the mass, or density, and volume of each applied finish.
    (b) Determine the mass of each applied finish with a scale 
calibrated to an accuracy of at least 5 percent of the amount measured. 
The quantity of all finishes used for finishing operations must be 
weighed or have a predetermined weight.
    (c) Determine the density and volume of each applied finish 
according to the criteria listed in paragraphs (c)(1) through (3) of 
this section:
    (1) Determine the density of each applied finish in pounds per 
gallon in accordance with Sec. 63.5395. The finish density will be used 
to convert applied finish volumes from gallons into mass units of 
pounds.
    (2) Volume measurements of each applied finish can be obtained with 
a flow measurement device. For each flow measurement device, you must 
perform the items listed in paragraphs (c)(2)(i) through (v) of this 
section:
    (i) Locate the flow sensor and other necessary equipment such as 
straightening vanes in or as close to a position that provides a 
representative flow.
    (ii) Use a flow sensor with a minimum tolerance of 2 percent of the 
flow rate.
    (iii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iv) Conduct a flow sensor calibration check at least semiannually.
    (v) At least monthly, inspect all components for integrity, all 
electrical connections for continuity, and all mechanical connections 
for leakage.
    (3) Volume measurements of each applied finish can be obtained with 
a calibrated volumetric container with an accuracy of at least 5 percent 
of the amount measured.



Sec. 63.5390  How do I measure the HAP content of a finish?

    (a) To determine the HAP content of a finish, the reference method 
is EPA Method 311 of appendix A of 40 CFR part 63. You may use EPA 
Method 311, an alternative method approved by the Administrator, or any 
other reasonable means for determining the HAP content. Other reasonable 
means of determining HAP content include, but are not limited to, a 
material safety data sheet (MSDS) or a manufacturer's hazardous air 
pollutant data sheet. If the HAP content is provided on a MSDS or a 
manufacturer's data sheet as a range of values, then the highest HAP 
value of the range must be used for the determination of compliance to 
this standard. This value must be entered on the finish log for each 
type of finish applied. You are not required to test the materials that 
you use, but the Administrator may require a test using EPA

[[Page 507]]

Method 311 (or another approved method) to confirm the reported HAP 
content. However, if the results of an analysis by EPA Method 311 are 
different from the HAP content determined by another means, the EPA 
Method 311 results will govern compliance determinations.
    (b) You may use the weighted average of the HAP content analysis as 
determined in paragraph (a) of this section for each finish when you 
perform one of the actions listed in paragraphs (b)(1) and (2) of this 
section:
    (1) Mix your own finishes on site.
    (2) Mix new quantities of finish with previous quantities of finish 
that may have a different HAP content.



Sec. 63.5395  How do I measure the density of a finish?

    (a) To determine the density of a finish, the reference method is 
EPA Method 24 of appendix A of 40 CFR part 60. You may use EPA Method 
24, an alternative method approved by the Administrator, or any other 
reasonable means for determining the density of a finish. Other 
reasonable means of determining density include, but are not limited to, 
an MSDS or a manufacturer's hazardous air pollutant data sheet. If the 
density is provided on a MSDS or a manufacturer's data sheet as a range 
of values, then the highest density value of the range must be used for 
the determination of compliance to this standard. This value must be 
entered on the finish log for each type of finish applied. You are not 
required to test the materials that you use, but the Administrator may 
require a test using EPA Method 24 (or another approved method) to 
confirm the reported density. However, if the results of an analysis by 
EPA Method 24 are different from the density determined by another 
means, the EPA Method 24 results will govern compliance determinations.
    (b) You may use the weighted average of finish densities as 
determined in paragraph (a) of this section for each finish when you 
perform one of the actions listed in paragraphs (b)(1) and (2) of this 
section:
    (1) Mix your own finishes on site.
    (2) Mix new quantities of finish with previous quantities of finish 
that may have different densities.
    (c) Equation 1 of this section may be used to determine the weighted 
average of finish densities, as follows:
[GRAPHIC] [TIFF OMITTED] TR27FE02.006

Where:

Average Weighted Density = The average weighted density of applied 
finishes in pounds per gallon.
Mass = Pounds of finish ``i'' applied.
Density = The density of finish ``i'' in pounds per gallon.
n = Number of finish types applied.



Sec. 63.5400  How do I measure the quantity of leather processed?

    (a) This section describes the information and procedures you must 
use to determine the quantity of leather processed at your affected 
source.
    (1) To determine the surface area (i.e., quantity) of leather 
substrate processed each month at your source for each product process 
operation, follow the procedures in your plan for demonstrating 
compliance. You must consistently measure the surface area of processed 
leather substrate at one of the manufacturing locations listed in 
paragraph (a)(1)(i) or (ii) of this section:
    (i) Measure the surface area of processed leather upon exiting the 
leather finishing operation.

[[Page 508]]

    (ii) Measure the surface area of processed leather upon shipment 
from the source.
    (2) By the fifteenth of each month, you must determine the quantity 
of leather processed in 1,000's of square feet for each product process 
operation during the previous month. After collecting data on the amount 
of leather processed for 12 months, you must also determine by the 
fifteenth of each month the annual total of leather processed in 1,000's 
of square feet for each product process operation by summing the monthly 
quantities of leather processed in each product process operation for 
the previous 12 months. The ``annual total of leather processed'' in 
each product process operation is used in Equation 1 of Sec. 63.5340 to 
calculate your allowable HAP loss as described in Sec. 63.5340. Your 
allowable HAP loss is then subsequently used to calculate your 
compliance ratio as described in Sec. 63.5330.
    (b) To determine the surface area of leather processed at your 
source for each product process operation, you must use one of the 
methods listed in paragraphs (b)(1) and (2) of this section:
    (1) Premeasured leather substrate sections being supplied by another 
manufacturer as an input to your finishing process.
    (2) Measure the surface area of each piece of processed or shipped 
leather with a computer scanning system accurate to 0.1 square feet. The 
computer scanning system must be initially calibrated for minimum 
accuracy to the manufacturer's specifications. For similar leather 
production runs, use an average based on a minimum of 500 pieces of 
leather in lieu of individual measurements.
    (c) Except as provided in paragraph (d) of this section, you must 
include the surface area of each piece of processed leather only once 
when determining the monthly quantity of leather processed, regardless 
of the number of times a piece of leather is reprocessed through a 
portion of the finishing operations.
    (d) If a piece of leather is completely stripped of all applied 
finishes and reprocessed through the entire finishing operation as if it 
were a new piece of leather, you may recount the surface area of leather 
reprocessed when determining the monthly quantity of leather processed.

                   Notifications, Reports, and Records



Sec. 63.5415  What notifications must I submit and when?

    (i) The plan for demonstrating compliance, as described in 
Sec. 63.5325, is complete and available on site for inspection.
    (ii) You are following the procedures described in the plan for 
demonstrating compliance.
    (iii) The compliance ratio value was determined to be less than or 
equal to 1.00, or the value was determined to be greater than 1.00.
    (g) If your source becomes a major source on or after February 27, 
2002, you must submit an initial notification not later than 120 days 
after you become subject to this subpart.



Sec. 63.5420  What reports must I submit and when?

    (a) You must submit the first annual compliance status certification 
12 months after you submit the Notification of Compliance Status. Each 
subsequent annual compliance status certification is due 12 months after 
the previous annual compliance status certification. The annual 
compliance status certification provides the compliance status for each 
month during the 12-month period ending 60 days prior to the date on

                   Other Requirements and Information



Sec. 63.5450  What parts of the General Provisions apply to me?

    Table 2 of this subpart shows which parts of the General Provisions 
in Secs. 63.1 through 63.15 apply to you.



Sec. 63.5455  Who administers this subpart?

    (a) This subpart can be administered by us, the United States 
Environmental Protection Agency (U.S. EPA), or a delegated authority 
such as your State, local, or tribal agency. If the U.S. EPA 
Administrator has delegated authority to your State, local, or tribal 
agency, then that agency has the primary authority to administer and 
enforce this subpart. You should contact your U.S. EPA Regional Office 
to find out if the authority to implement and enforce this subpart is 
delegated to your State, local, or tribal agency.
    (b) In delegating implementation and enforcement authority of this 
subpart to a State, local, or tribal agency under subpart E of this 
part, the authorities contained in paragraph (c) of this section are 
retained by the Administrator of U.S. EPA and are not transferred to the 
State, local, or tribal agency.
    (c) The authorities that will not be delegated to State, local, or 
tribal agencies are listed in paragraphs (c)(1) through (4) of this 
section:
    (1) Approval of alternatives to the emission standards in 
Sec. 63.5305 under Sec. 63.6(g).

[[Page 511]]

    (2) Approval of major alternatives to test methods under 
Sec. 63.7(e)(2)(ii) and (f) and as defined in Sec. 63.90.
    (3) Approval of major alternatives to monitoring under Sec. 63.8(f) 
and as defined in Sec. 63.90.
    (4) Approval of major alternatives to recordkeeping and reporting 
under Sec. 63.10(f) and as defined in Sec. 63.90.



Sec. 63.5460  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, 
Sec. 63.2, and in this section as follows:
    Area source means any stationary source of hazardous air pollutants 
that is not a major source as defined in this part.
    Compliance ratio means the ratio of the actual HAP loss from the 
previous 12 months to the allowable HAP loss from the previous 12 
months. Equation 1 in Sec. 63.5330 is used to calculate this value. If 
the value is less than or equal to 1.00, the source is in compliance. If 
the value is greater than 1.00, the source is deviating from compliance.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limits or work 
practice standards.
    (2) Fails to meet any emission limits, operating limits, or work 
practice standards in this subpart during startup, shutdown, or 
malfunction, regardless of whether or not such failure is permitted by 
this subpart.
    Drying means the process of removing all but equilibrium moisture 
from the leather. Drying methods currently in use include: toggling, 
hanging, pasting, and vacuum drying.
    Finish add-on means the amount of solid material deposited on the 
leather substrate due to finishing operations. Typically, the solid 
deposition is a dye or other chemical used to enhance the color and 
performance of the leather. Finish add-on is quantified as mass per 
surface area of substrate, such as grams of finish add-on per square 
foot of leather substrate.
    Hazardous air pollutants (HAP) means any substance or mixture of 
substances listed as a hazardous air pollutant under section 112(b) of 
the Clean Air Act.
    Leather means the pelt or hide of an animal which has been 
transformed by a tanning process into a nonputrescible and useful 
material.
    Leather finishing means a single process or group of processes used 
to adjust and improve the physical and aesthetic characteristics of the 
leather surface through the multistage application of a coating 
comprised of dyes, pigments, film-forming materials, and performance 
modifiers dissolved or suspended in liquid carriers.
    Leather substrate means a nonputrescible leather surface intended 
for the application of finishing chemicals and materials. The leather 
substrate may be a continuous piece of material such as side leather or 
may be a combination of smaller leather pieces and leather fibers, which 
when joined together, form a integral composite leather material.
    Leather tanning means the processes, commonly referred to as wet 
operations, used to purify and stabilize the collagen content of the 
hide. Wet operations are divided into three phases, the beamhouse 
(includes soaking and unhairing); the tanyard (includes bating, 
pickling, tanning, trimming/siding, and splitting); and the coloring 
department (includes retanning, coloring, and atliquoring operations).
    Month means that all references to a month in this subpart refer to 
a calendar month.
    Nonwater-resistant leather means nonupholstery leather that is not 
treated with any type of waterproof finish and, thus, cannot withstand 
5,000 Maeser Flexes with a Maeser Flex Testing Machine or a method 
approved by the Administrator prior to initial water penetration. This 
leather is typically used for dress shoes, handbags, and garments.
    Product process operation means any one of the four leather 
production classifications developed for ease of compliance with this 
subpart. The four leather product process operations are as follows: 
upholstery leather with greater than or equal to 4 grams finish add-on 
per square foot, upholstery leather with less than 4 grams finish

[[Page 512]]

add-on per square foot, water-resistant/specialty leather, and nonwater-
resistant leather.
    Specialty leather means a select grade of chrome tanned, bark 
retanned, or fat liquored leather that is retanned through the 
application of greases, waxes, and oils in quantities greater than 25 
percent of the dry leather weight. Specialty leather is also finished 
with higher solvent-based finishes that provide rich color, luster, or 
an oily/tacky feel. Specialty leather products are generally low volume, 
high-quality leather, such as specialty shoe leather and top grade 
football leathers.
    Upholstery leather (greater than or equal to 4 grams finish add-on 
per square foot) means an upholstery leather with a final finish add-on 
to leather ratio of 4 or more grams of finish per square foot of 
leather. These types of finishes are used primarily for automobile 
seating covers. These finishes tend to be aqueous-based.
    Upholstery leather (less than 4 grams finish add-on per square foot) 
means an upholstery leather with a final finish add-on to leather ratio 
of less than 4 grams of finish per square foot of leather. These types 
of finishes are typically used for furniture seating covers. The 
finishes tend to be solvent-based and leave a thinner, softer, and more 
natural leather texture.
    Water-resistant leather means nonupholstery leather that has been 
treated with one or more waterproof finishes such that the leather can 
withstand 5,000 or more Maeser Flexes with a Maeser Flex Testing Machine 
or a method approved by the Administrator prior to initial water 
penetration. This leather is used for outerwear, boots and outdoor 
applications.

 Subpart UUUU--National Emission Standards for Hazardous Air Pollutants 
                  for Cellulose Products Manufacturing

    Source: 67 FR 40055, June 11, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5480  What is the purpose of this subpart?

    This subpart establishes emission limits, operating limits, and work 
practice standards for hazardous air pollutants (HAP) emitted from 
cellulose products manufacturing operations. Carbon disulfide, carbonyl 
sulfide, ethylene oxide, methanol, methyl chloride, propylene oxide, and 
toluene are the HAP emitted in the greatest quantities from cellulose 
products manufacturing operations. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limits, operating limits, and work practice standards.



Sec. 63.5485  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a cellulose 
products manufacturing operation that is located at a major source of 
HAP emissions.
    (a) Cellulose products manufacturing includes both the Miscellaneous 
Viscose Processes source category and the Cellulose Ethers Production 
source category. The Miscellaneous Viscose Processes source category 
includes all of the operations that use the viscose process. These 
operations include the cellulose food casing, rayon, cellulosic sponge, 
and cellophane operations, as defined in Sec. 63.5610. The Cellulose 
Ethers Production source category includes all of the cellulose ether 
operations, as defined in Sec. 63.5610, that use the cellulose ether 
process.
    (b) A major source of HAP is any stationary source or group of 
stationary sources located within a contiguous area and under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.1 megagrams per year (Mg/yr) (10 tons per year (tpy)) or more or 
any combination of HAP at a rate of 23 Mg/yr (25 tpy) or more.
    (c) The provisions of this subpart do not apply to research and 
development facilities, as defined in section 112(b)(7) of the Clean Air 
Act (CAA), regardless of whether the facilities are located at the same 
plant site as an operation subject to the provisions of this subpart.
    (d) For cellulose ether operations, the applicability provisions in 
paragraph (d)(1) or (2) of this section apply.
    (1) The applicability provisions in Secs. 63.100(a) through (f) and 
63.160 apply if you are complying with the equipment leak provisions of 
subpart H of this part.
    (2) The applicability provisions in Sec. 63.1019 apply if you are 
complying with the equipment leak provisions in subpart UU of this part.
    (e) For cellulose ether operations, the applicability provisions in 
Secs. 63.100(a) through (f) and 63.110(a), (e) and (h) apply if you are 
complying with the wastewater provisions in subparts F and G of this 
part.



Sec. 63.5490  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source for the Miscellaneous Viscose Processes and Cellulose 
Ethers Production source categories.
    (b) The affected source for the Miscellaneous Viscose Processes 
source category is each cellulose food casing, rayon, cellulosic sponge, 
or cellophane operation, as defined in Sec. 63.5610. The affected source 
for the Cellulose Ethers Production source category is each cellulose 
ether operation, as defined in Sec. 63.5610.
    (c) You must consider storage vessels to be part of your process 
unit, as defined in Sec. 63.5610, under either of the conditions 
described in paragraphs (c)(1) and (2) of this section. Otherwise, you 
may assign your storage vessels according to paragraph (c)(3) or (4) of 
this section.
    (1) The input to the storage vessel from your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
input from any other process.

[[Page 516]]

    (2) The output from the storage vessel to your viscose process or 
cellulose ether process (either directly or through other storage 
vessels assigned to your process unit) is greater than or equal to the 
output to any other process.
    (3) If the greatest input to and/or output from a shared storage 
vessel is the same for two or more processes, including at least one 
viscose process or cellulose ether process, you may assign the storage 
vessel to any process unit that has the greatest input or output.
    (4) If the use varies from year to year, then you must base the 
determination on the utilization that occurred during the year preceding 
June 11, 2002 or, if the storage vessel was not operating during that 
year, you must base the use on the expected use for the first 5-year 
period after startup. You must include this determination in the 
Notification of Compliance Status Report specified in Table 7 to this 
subpart.
    (d) An affected source is a new affected source if you began 
construction of the affected source after August 28, 2000 and you meet 
the applicability criteria in Sec. 63.5485 at the time you began 
construction.
    (e) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (f) An affected source is existing if it is not new or 
reconstructed.
    (g) For the purposes of this subpart, the definitions of new and 
existing affected source in paragraphs (d) through (f) of this section 
supersede the definitions of new and existing affected source in 
subparts F, G, H, U and UU of this part.

[GRAPHIC] [TIFF OMITTED] TR11JN02.006

Where:
CE = control efficiency, percent.
ERi = total emission rate of organic HAP (ERHAPt) 
or sulfide (ERsulft) in the inlet vent stream of the control 
device, kg/hr (lb/hr).
ERo = total emission rate of organic HAP (ERHAPt) 
or sulfide (ERsulft) in the outlet vent stream of the control 
device, kg/hr (lb/hr).

limit or work practice standard in Table 1 to this subpart, you must 
comply with the requirements in paragraphs (f)(1) through (3) of this 
section. You are not required to conduct a performance test to determine 
the control efficiency of the flare or the outlet organic HAP 
concentration. If you have previously conducted a compliance 
demonstration for a flare using the techniques specified in paragraphs 
(f)(1) through (3) of this section, you may use that compliance 
demonstration to satisfy the requirements of this paragraph if either no 
deliberate process changes have been made since the compliance 
demonstration, or the results of the compliance demonstration reliably 
demonstrate compliance despite process changes.

establish each site-specific operating limit in Table 2 to this subpart 
that applies to you according to the requirements in paragraphs (h)(1) 
through (10) of this section.
    (1) For continuous process vents and combinations of batch and 
continuous process vents, establish your site-specific operating limit 
using the procedures in Sec. 63.505(b)(2), except that, if you 
demonstrate initial compliance using a month-long compliance 
demonstration, references to ``compliance testing'' and ``1-hour runs'' 
mean ``compliance demonstration'' and references to ``three test runs'' 
mean ``daily averages during the compliance demonstration'' for purposes 
of this subpart.
    (2) For batch process vents, establish your site-specific operating 
limit using the procedures in Sec. 63.505(b)(3), except that, if you 
demonstrate initial compliance using a month-long compliance 
demonstration, references to ``compliance testing'' and ``performance 
test'' mean ``compliance demonstration'' for purposes of this subpart.
    (3) For condensers, record the outlet (product side) gas or 
condensed liquid temperature averaged over the same period as the 
compliance demonstration while the vent stream is routed and constituted 
normally. Locate the temperature sensor in a position that provides a 
representative temperature.

pilot flame sensor in a position that provides an accurate and 
continuous determination of the presence of the pilot flame.
    (8) For biofilters, record the pressure drop across the biofilter 
beds, inlet gas temperature, and effluent pH, averaged over the same 
time period as the compliance demonstration while the vent stream is 
routed and constituted normally. Locate the pressure, temperature, and 
pH sensors in positions that provide representative measurement of these 
parameters. Ensure the sample is properly mixed and representative of 
the fluid to be measured.
    (9) For carbon adsorbers, record the total regeneration stream mass 
or volumetric flow during each carbon bed regeneration cycle during the 
period of the compliance demonstration. Record the temperature of the 
carbon bed after each carbon bed regeneration cycle during the period of 
the compliance demonstration (and within 15 minutes of completion of any 
cooling cycle(s)).

[[Page 521]]

Record the operating time since the end of the last carbon bed 
regeneration cycle and the beginning of the next carbon bed regeneration 
cycle during the period of the compliance demonstration. Locate the 
temperature and flow sensors in positions that provide representative 
measurement of these parameters.
    (10) For oil absorbers, record the flow of absorption liquid through 
the absorber, the temperatures of the absorption liquid before and after 
the steam stripper, and the steam flow through the steam stripper 
averaged during the same period of the compliance demonstration. Locate 
the temperature and flow sensors in positions that provide 
representative measurement of these parameters.

                   Continuous Compliance Requirements



Sec. 63.5555  How do I demonstrate continuous compliance with the emission limits, operating limits, and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limit, operating limit, and work practice standard in Tables 1 and 2 to 
this subpart that applies to you according to methods specified in 
Tables 5 and 6 to this subpart.
    (b) You must report each instance in which you were not in 
continuous compliance (as specified in Tables 5 and 6 to this subpart) 
with each emission limit, each operating limit, and each work practice 
standard that apply to you. This includes periods of startup, shutdown, 
and malfunction. These instances are deviations from the emission 
limits, operating limits, and work practice standards in this subpart. 
These deviations must be reported according to the requirements in 
Sec. 63.5580.
    (c) During periods of startup, shutdown, and malfunction, you must 
operate according to the SSM plan.
    (d) Consistent with Secs. 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 according to the SSM plan.



Sec. 63.5560  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.

[[Page 523]]

    (b) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times that the affected source is operating, including 
periods of startup, shutdown, and malfunction.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, required quality assurance or control activities, 
and periods of no flow for all or a portion of an affected source in 
data averages and calculations used to report emission or operating 
levels, nor may such data be used in 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.
    (d) All terms in this subpart that define a period of time for 
completing required tasks (e.g., weekly, monthly, quarterly, or 
annually) refer to the standard calendar periods.
    (1) You may change time periods specified in this subpart for 
completing required tasks by mutual agreement with the Administrator, as 
specified in subpart A of this part. For example, a period could begin 
on the compliance date or another date, rather than on the first day of 
the standard calendar period. For each time period that is changed by 
agreement, the revised period must remain in effect until it is changed. 
A new request is not necessary for each recurring period.
    (2) Where the period specified for compliance is a standard calendar 
period, if the initial compliance date occurs after the beginning of the 
period, then you must comply according to the schedule specified in 
paragraph (d)(2)(i) or (ii) of this section, as appropriate.
    (i) You must comply before the end of the standard calendar period 
within which the compliance deadline occurs, if there remain at least 3 
days for tasks that must be performed weekly, at least 2 weeks for tasks 
that must be performed monthly, at least 1 month for tasks that must be 
performed quarterly, or at least 3 months for tasks that must be 
performed annually; or
    (ii) In all instances where a provision of this subpart requires 
completing a task during each of multiple successive periods, you may 
perform the required task at any time during the specified period, 
provided that the task is conducted at a reasonable interval after 
completion of the task during the previous period.

 Subpart VVVV--National Emission Standards for Hazardous Air Pollutants 
                         for Boat Manufacturing

    Source: 66 FR 44232, Aug. 22, 2001, unless otherwise noted.

                         What the Subpart Covers



Sec. 63.5680  What is the purpose of this subpart?

    (a) This subpart establishes national emission standards for 
hazardous air pollutants (HAP) for new and existing

[[Page 570]]

boat manufacturing facilities with resin and gel coat operations, carpet 
and fabric adhesive operations, or aluminum recreational boat surface 
coating operations. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the emission 
standards.



Sec. 63.5683  Does this subpart apply to me?

    (a) This subpart applies to you if you meet both of the criteria 
listed in paragraphs (a)(1) and (2) of this section.
    (1) You are the owner or operator of a boat manufacturing facility 
that builds fiberglass boats or aluminum recreational boats.
    (2) Your boat manufacturing facility is a major source of HAP either 
in and of itself, or because it is collocated with other sources of HAP, 
such that all sources combined constitute a major source.
    (b) A boat manufacturing facility is a facility that manufactures 
hulls or decks of boats from fiberglass or aluminum, or assembles boats 
from premanufactured hulls and decks, or builds molds to make fiberglass 
hulls or decks. A facility that manufactures only parts of boats (such 
as hatches, seats, or lockers) or boat trailers is not considered a boat 
manufacturing facility for the purpose of this subpart.
    (c) A major source is any stationary source or group of stationary 
sources located within a contiguous area and under common control that 
emits or can potentially emit, considering controls, in the aggregate, 
9.1 megagrams (10 tons) or more per year of a single HAP or 22.7 
megagrams (25 tons) or more per year of a combination of HAP.
    (d) This subpart does not apply to aluminum coating operations on 
aluminum boats intended for commercial or military (nonrecreational) 
use, antifoulant coatings, assembly adhesives, fiberglass hull and deck 
coatings, research and development activities, mold sealing and release 
agents, mold stripping and cleaning solvents, and wood coatings as 
defined in Sec. 63.5779. This subpart does not apply to materials 
contained in handheld aerosol cans.



Sec. 63.5686  How do I demonstrate that my facility is not a major source?

    You can demonstrate that your facility is not a major source by 
using the procedures in either paragraph (a) or (b) of this section.
    (a) Emission option. You must demonstrate that your facility does 
not emit, and does not have the potential to emit as defined in 
Sec. 63.2, considering federally enforceable permit limits, 9.1 
megagrams (10 tons) or more per year of a single HAP or 22.7 megagrams 
(25 tons) or more per year of a combination of HAP. To calculate your 
facility's potential to emit, you must include emissions from the boat 
manufacturing facility and all other sources that are collocated and 
under common ownership or control with the boat manufacturing facility.
    (b) Material consumption option. This option can be used if you 
manufacture either fiberglass boats or aluminum recreational boats at 
your facility. You must meet the criteria in paragraph (b)(1), (2), or 
(3) of this section and comply with the requirements in paragraph (c) of 
this section. If you initially rely on the limits and criteria specified 
in paragraph (b)(1), (2), or (3) of this section to become an area 
source, but then exceed the relevant limit (without first obtaining and 
complying with other limits that keep your potential to emit HAP below 
major source levels), your facility will then become a major source, and 
you must comply with all applicable provisions of this subpart beginning 
on the compliance date specified in Sec. 63.5695. Nothing in this 
paragraph is intended to preclude you from limiting your facility's 
potential to emit through other federally enforceable mechanisms 
available through your permitting authority.
    (1) If your facility is primarily a fiberglass boat manufacturing 
facility, you must demonstrate that you consume less than 45.4 megagrams 
per rolling 12-month period of all combined polyester-and vinylester-
based resins and gel coats (including tooling and production resins and 
gel coats, and clear gel coats), and you must demonstrate that at least 
90 percent of

[[Page 571]]

total annual HAP emissions at the facility (including emissions from 
aluminum recreational boat manufacturing or other source categories) 
originate from the fiberglass boat manufacturing materials.
    (2) If your facility is primarily an aluminum recreational boat 
manufacturing facility, you must demonstrate that it consumes less than 
18.2 megagrams per rolling 12-month period of all combined surface 
coatings, aluminum wipedown solvents, application gun cleaning solvents, 
and carpet and fabric adhesives; and you must demonstrate that at least 
90 percent of total annual HAP emissions at the facility (including 
emissions from fiberglass boat manufacturing or other source categories) 
originate from the aluminum recreational boat manufacturing materials.
    (3) If your facility is a fiberglass boat or an aluminum 
recreational boat manufacturing facility, you must demonstrate that the 
boat manufacturing materials consumed per rolling 12-month period 
contain a total of less than 4.6 megagrams of any single HAP and less 
than 11.4 megagrams of all combined HAP, and you must demonstrate that 
at least 90 percent of total annual HAP emissions at the facility 
(including emissions from other source categories) originate from these 
boat manufacturing materials.
    (c) If you use the material consumption option described in 
paragraph (b) of this section to demonstrate that you are not a major 
source, you must comply with the requirements of paragraphs (c)(1) 
through (3) of this section.
    (1) If your facility has HAP emissions that do not originate from 
boat manufacturing operations or materials described in paragraph (b), 
then you must keep any records necessary to demonstrate that the 90 
percent criterion is met.
    (2) A rolling 12-month period includes the previous 12 months of 
operation. You must maintain records of the total amount of materials 
described in paragraph (b) of this section used each month, and, if 
necessary, the HAP content of each material and the calculation of the 
total HAP consumed each month. Because records are needed for a 12-month 
period, you must keep records beginning no later than 12 months before 
the compliance date specified in Sec. 63.5695. Records must be kept for 
5 years after they are created.
    (3) In determining whether the 90 percent criterion included in 
paragraph (b) of this section is met, you do not need to include 
materials used in routine janitorial, building, or facility grounds 
maintenance; personal uses by employees or other persons; or products 
used for maintaining motor vehicles operated by the facility.



Sec. 63.5689  What parts of my facility are covered by this subpart?

    The affected source (the portion of your boat manufacturing facility 
covered by this subpart) is the combination of all of the boat 
manufacturing operations listed in paragraphs (a) through (f) of this 
section.
    (a) Open molding resin and gel coat operations (including pigmented 
gel coat, clear gel coat, production resin, tooling gel coat, and 
tooling resin).
    (b) Closed molding resin operations.
    (c) Resin and gel coat mixing operations.
    (d) Resin and gel coat application equipment cleaning operations.
    (e) Carpet and fabric adhesive operations.
    (f) Aluminum hull and deck coating operations, including solvent 
wipedown operations and paint spray gun cleaning operations, on aluminum 
recreational boats.



Sec. 63.5692  How do I know if my boat manufacturing facility is a new source or an existing source?

    (a) A boat manufacturing facility is a new source if it meets the 
criteria in paragraphs (a)(1) through (3) of this section.
    (1) You commence construction of the affected source after July 14, 
2000.
    (2) It is a major source.
    (3) It is a completely new boat manufacturing affected source where 
no other boat manufacturing affected source existed prior to the 
construction of the new source.
    (b) For the purposes of this subpart, an existing source is any 
source that is not a new source.

Sec. 63.5695  When must I comply with this subpart?

    You must comply with the standards in this subpart by the compliance 
dates specified in Table 1 to this subpart.

        Standards for Open Molding Resin and Gel Coat Operations



Sec. 63.5698  What emission limit must I meet for open molding resin and gel coat operations?

    (a) You must limit organic HAP emissions from the five open molding 
operations listed in paragraphs (a)(1) through (5) of this section to 
the emission limit specified in paragraph (b) of this section. 
Operations listed in paragraph (d) are exempt from this limit.
    (1) Production resin.
    (2) Pigmented gel coat.
    (3) Clear gel coat.
    (4) Tooling resin.
    (5) Tooling gel coat.
    (b) You must limit organic HAP emissions from open molding 
operations to the limit specified by equation 1 of this section, based 
on a 12-month rolling average.
[GRAPHIC] [TIFF OMITTED] TR22AU01.011

Where:

HAP Limit= total allowable organic HAP that can be emitted from the open 
molding operations, kilograms.
MR = mass of production resin used in the past 12 months, 
excluding any materials exempt under paragraph (d) of this section, 
megagrams.
MPG = mass of pigmented gel coat used in the past 12 months, 
excluding any materials exempt under paragraph (d) of this section, 
megagrams.
MCG = mass of clear gel coat used in the past 12 months, 
excluding any materials exempt under paragraph (d) of this section, 
megagrams.
MTR = mass of tooling resin used in the past 12 months, 
excluding any materials exempt under paragraph (d) of this section, 
megagrams.
MTG = mass of tooling gel coat used in the past 12 months, 
excluding any materials exempt under paragraph (d) of this section, 
megagrams.

    (c) The open molding emission limit is the same for both new and 
existing sources.
    (d) The materials specified in paragraphs (d)(1) through (3) of this 
section are exempt from the open molding emission limit specified in 
paragraph (b) of this section.
    (1) Production resins (including skin coat resins) that must meet 
specifications for use in military vessels or must be approved by the 
U.S. Coast Guard for use in the construction of lifeboats, rescue boats, 
and other life-saving appliances approved under 46 CFR subchapter Q or 
the construction of small passenger vessels regulated by 46 CFR 
subchapter T. Production resins for which this exemption is used must be 
applied with nonatomizing (non-spray) resin application equipment. You 
must keep a record of the resins for which you are using this exemption.
    (2) Pigmented, clear, and tooling gel coat used for part or mold 
repair and touch up. The total gel coat materials included in this 
exemption must not exceed 1 percent by weight of all gel coat used at 
your facility on a 12-month rolling-average basis. You must keep a 
record of the amount of gel coats used per month for which you are using 
this exemption and copies of calculations showing that the exempt amount 
does not exceed 1 percent of all gel coat used.
    (3) Pure, 100 percent vinylester resin used for skin coats. This 
exemption does not apply to blends of vinylester and polyester resins 
used for skin coats. The total resin materials included in the exemption 
cannot exceed 5 percent by weight of all resin used at your facility on 
a 12-month rolling-average basis. You must keep a record of the amount 
of 100 percent vinylester skin coat resin used per month that is 
eligible for this exemption and copies

[[Page 573]]

of calculations showing that the exempt amount does not exceed 5 percent 
of all resin used.



Sec. 63.5701  What are my options for complying with the open molding emission limit?

    You must use one or more of the options listed in paragraphs (a) 
through (c) of this section to meet the emission limit in Sec. 63.5698 
for the resins and gel coats used in open molding operations at your 
facility.
    (a) Maximum achievable control technology (MACT) model point value 
averaging (emissions averaging) option.
    (1) Demonstrate that emissions from the open molding resin and gel 
coat operations that you average meet the emission limit in Sec. 63.5698 
using the procedures described in Sec. 63.5710. Compliance with this 
option is based on a 12-month rolling average.
    (2) Those operations and materials not included in the emissions 
average must comply with either paragraph (b) or (c) of this section.
    (b) Compliant materials option. Demonstrate compliance by using 
resins and gel coats that meet the organic HAP content requirements in 
Table 2 to this subpart. Compliance with this option is based on a 12-
month rolling average.
    (c) Add-on control option. Use an enclosure and add-on control

revised plan with your next semiannual compliance report specified in 
Sec. 63.5764.



Sec. 63.5710  How do I demonstrate compliance using emissions averaging?

    (a) Compliance using the emissions averaging option is demonstrated 
on a 12-month rolling-average basis and is determined at the end of 
every month (12 times per year). The first 12-month rolling-average 
period begins on the compliance date specified in Sec. 63.5695.
    (b) At the end of the twelfth month after your compliance date and 
at the end of every subsequent month, use equation 1 of this section to 
demonstrate that the organic HAP emissions from those operations 
included in the average do not exceed the emission limit in Sec. 63.5698 
calculated for the same 12-month period. (Include terms in equation 1 of 
Sec. 63.5698 and equation 1 of this section for only those operations 
and materials included in the average.)

[66 FR 44232, Aug. 22, 2001; 66 FR 50504, Oct. 3, 2001]



Sec. 63.5713  How do I demonstrate compliance using compliant materials?

    (a) Compliance using the organic HAP content requirements listed in 
Table 2 to this subpart is based on a 12-month rolling average that is 
calculated at the end of every month. The first 12-month rolling-average 
period begins on the compliance date specified in Sec. 63.5695. If you 
are using filled material (production resin or tooling resin), you must 
comply according to the procedure described in Sec. 63.5714.
    (b) At the end of the twelfth month after your compliance date and 
at the end of every subsequent month, review the organic HAP contents of 
the resins and gel coats used in the past 12 months in each operation. 
If all resins and gel coats used in an operation have organic HAP 
contents no greater than the applicable organic HAP content limits in 
Table 2 to this subpart, then you are in compliance with the emission 
limit specified in Sec. 63.5698 for that 12-month period for that 
operation. In addition, you do not need to complete the weighted-average 
organic HAP content calculation contained in paragraph (c) of this 
section for that operation.
    (c) At the end of every month, you must use equation 1 of this 
section to calculate the weighted-average organic HAP content for all 
resins and gel coats used in each operation in the past 12 months.

[[Page 576]]

[GRAPHIC] [TIFF OMITTED] TR22AU01.014

Where:

Mi = mass of open molding resin or gel coat i used in the 
past 12 months in an operation, megagrams.
HAPi = Organic HAP content, by weight percent, of open 
molding resin or gel coat i used in the past 12 months in an operation. 
Use the methods in Sec. 63.5758 to determine organic HAP content.
n = number of different open molding resins or gel coats used in the 
past 12 months in an operation.

    (d) If the weighted-average organic HAP content does not exceed the 
applicable organic HAP content limit specified in Table 2 to this 
subpart, then you are in compliance with the emission limit specified in 
Sec. 63.5698.



Sec. 63.5714  How do I demonstrate compliance if I use filled resins?

    (a) If you are using a filled production resin or filled tooling 
resin, you must demonstrate compliance for the filled material on an as-
applied basis using equation 1 of this section.
[GRAPHIC] [TIFF OMITTED] TR22AU01.015

Where:

PVF = The as-applied MACT model point value for a filled 
production resin or tooling resin, kilograms organic HAP per megagram of 
filled material.

system.

    (b) If the filled resin is used as a production resin and the value 
of PVF calculated by equation 1 of this section does not 
exceed 46 kilograms of organic HAP per megagram of filled resin applied, 
then the filled resin is in compliance.
    (c) If the filled resin is used as a tooling resin and the value of 
PVF calculated by equation 1 of this section does not exceed 
54 kilograms of organic HAP per megagram of filled resin applied, then 
the filled resin is in compliance.
    (d) If you are including a filled resin in the emissions averaging 
procedure described in Sec. 63.5710, then use the value of 
PVF calculated using equation 1 of this section for the value 
of PV i in equation 2 of Sec. 63.5710.

 Demonstrating Compliance for Open Molding Operations Controlled by Add-
                           On Control Devices



Sec. 63.5715  What operating limits must I meet?

    (a) For open molding operations on which you use a thermal oxidizer 
as an add-on control device, you must meet the operating limits 
specified in Table 4 to this subpart that apply to the emission capture 
system and thermal oxidizer. You must establish the operating limits 
during the performance test according to the procedures in Sec. 63.5725. 
You must meet the operating limits at all times after you establish 
them.
    (b) If you use an add-on control device other than a thermal 
oxidizer, or wish to monitor an alternative parameter and comply with a 
different operating limit, you must apply to the Administrator for 
approval of alternative monitoring under Sec. 63.8(f).



Sec. 63.5716  When must I conduct a performance test?

    (a) If your source is an existing source, you must complete the add-
on control device performance test no later than the compliance date 
specified in Sec. 63.5695.

[[Page 577]]

    (b) If your source is a new source, you must complete the add-on 
control device performance test no later than 180 days after the 
compliance date specified in Sec. 63.5695.
    (c) You must conduct a performance test every 5 years as part of 
renewing your 40 CFR part 70 or 71 operating permit.



Sec. 63.5719  How do I conduct a performance test?

    (a) You must capture the emissions using a permanent enclosure (such 
as a spray booth or similar containment device) and direct the captured 
emissions to the add-on control device.
    (b) You must measure emissions as specified in paragraph (b)(1) or 
(2) of this section.
    (1) If the enclosure vented to the control device is a permanent 
total enclosure as defined in Method 204 of appendix M to 40 CFR part 
51, then you may measure emissions only at the outlet of the control 
device.
    (2) If the permanent enclosure vented to the control device is not a 
total enclosure, you must build a temporary total enclosure, as defined 
in Method 204 of appendix M to 40 CFR part 51, around the permanent 
enclosure. You must then simultaneously measure emissions from the 
control device outlet and the emissions from the temporary total 
enclosure outlet. You determine compliance from the combined emissions 
from the control device outlet and the temporary total enclosure outlet.
    (c) You must conduct the control device performance test using the 
emission measurement methods specified in paragraphs (c)(1) through (4) 
of this section.
    (1) Use either Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select the sampling sites.
    (2) Use Method 2, 2A, 2C, 2D, 2F or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 18 of appendix A to 40 CFR part 60 to measure organic 
HAP emissions or use Method 25A of appendix A to 40 CFR part 60 to 
measure total gaseous organic emissions as a surrogate for total organic 
HAP emissions. If you use Method 25A, you must assume that all gaseous 
organic emissions measured as carbon are organic HAP emissions. If you 
use Method 18 and the number of organic HAP in the exhaust stream 
exceeds five, you must take into account the use of multiple 
chromatographic columns and analytical techniques to get an accurate 
measure of at least 90 percent of the total organic HAP mass emissions. 
Do not use Method 18 to measure organic HAP emissions from a combustion 
device; use instead Method 25A and assume that all gaseous organic mass 
emissions measured as carbon are organic HAP emissions.
    (4) You may use American Society for Testing and Materials (ASTM) 
D6420-99 (available for purchase from at least one of the following 
addresses: 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959; or 
University Microfilms International, 300 North Zeeb Road, Ann Arbor, MI 
48106.) in lieu of Method 18 of 40 CFR part 60, appendix A, under the 
conditions specified in paragraphs (c)(4)(i) through (iii) of this 
section.
    (i) If the target compound(s) is listed in Section 1.1 of ASTM 
D6420-99 and the target concentration is between 150 parts per billion 
by volume and 100 parts per million by volume.
    (ii) If the target compound(s) is not listed in Section 1.1 of ASTM 
D6420-99, but is potentially detected by mass spectrometry, an 
additional system continuing calibration check after each run, as 
detailed in Section 10.5.3 of ASTM D6420-99, must be followed, met, 
documented, and submitted with the performance test report even if you 
do not use a moisture condenser or the compound is not considered 
soluble.
    (iii) If a minimum of one sample/analysis cycle is completed at 
least every 15 minutes.
    (d) The control device performance test must consist of three runs 
and each run must last at least 1 hour. The production conditions during 
the test runs must represent normal production conditions with respect 
to the types of parts being made and material application methods. The 
production conditions during the test must also represent maximum 
potential emissions

[[Page 578]]

with respect to the organic HAP content of the materials being applied 
and the material application rates.
    (e) During the test, you must also monitor and record separately the 
amounts of production resin, tooling resin, pigmented gel coat, clear 
gel coat, and tooling gel coat applied inside the enclosure that is 
vented to the control device.



Sec. 63.5722  How do I use the performance test data to demonstrate initial compliance?

    Demonstrate initial compliance with the open molding emission limit 
as described in paragraphs (a) through (c) of this section:
    (a) Calculate the organic HAP limit you must achieve using equation 
1 of Sec. 63.5698. For determining initial compliance, the organic HAP 
limit is based on the amount of material used during the performance 
test, in megagrams, rather than during the past 12 months. Calculate the 
limit using the megagrams of resin and gel coat applied inside the 
enclosure during the three runs of the performance test and equation 1 
of Sec. 63.5698.
    (b) Add the total measured emissions, in kilograms, from all three 
of the 1-hour runs of the performance test.
    (c) If the total emissions from the three 1-hour runs of the 
performance test are less than the organic HAP limit calculated in 
paragraph (a) of this section, then you have demonstrated initial 
compliance with the emission limit in Sec. 63.5698 for those operations 
performed in the enclosure and controlled by the add-on control device.



Sec. 63.5725  What are the requirements for monitoring and demonstrating continuous compliance?

    (a) You must establish control device parameters that indicate 
proper operation of the control device.
    (b) You must install, operate, and maintain a continuous parameter 
monitoring system as specified in paragraphs (b)(1) through (8) of this 
section.
    (1) The continuous parameter monitoring system must complete a 
minimum of one cycle of operation for each successive 15-minute period. 
You must have a minimum of four successive cycles of operation to have a 
valid hour of data.
    (2) You must have valid data from at least 90 percent of the hours 
during which the process operated.
    (3) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (4) You must maintain the continuous parameter monitoring system at 
all times and have available necessary parts for routine repairs of the 
monitoring equipment.
    (5) You must operate the continuous parameter monitoring system and 
collect emission capture system and add-on control device parameter data 
at all times that a controlled open molding operation is being 
performed, except during monitoring malfunctions, associated repairs, 
and required quality assurance or control activities (including, if 
applicable, calibration checks and required zero and span adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) You must record the results of each inspection, calibration, and 
validation check.
    (8) Any period for which the monitoring system is out-of-control, as 
defined in Sec. 63.7(d)(7), or malfunctioning, and data are not 
available for required calculations is a deviation from the monitoring 
requirements. A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the continuous parameter monitoring 
system to provide valid data. Monitoring failures that are caused in 
part by poor maintenance or careless operation are not malfunctions.
    (c) Enclosure bypass line. You must meet the requirements of 
paragraphs

[[Page 579]]

(c)(1) and (2) of this section for each emission capture system 
enclosure that contains bypass lines that could divert emissions away 
from the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the valve was opened. The method used to monitor or secure 
the valve or closure mechanism must meet one of the requirements 
specified in paragraphs (c)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure continuous monitoring. Ensure that any bypass 
line valve is in the closed (non-diverting) position through monitoring 
of valve position at least once every 15 minutes. You must inspect the 
monitoring system at least once every month to verify that the monitor 
will indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the open molding operation is stopped when flow is diverted by the 
bypass line away from the add-on control device to the atmosphere when 
the open molding operation is running. You must inspect the automatic 
shutdown system at least once every month to verify that it will detect 
diversions of flow and shut down the open molding operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.5764(d).
    (d) Thermal oxidizers. If you are using a thermal oxidizer or 
incinerator as an add-on control device, you must comply with the 
requirements in paragraphs (d)(1) through (6) of this section.
    (1) You must install a combustion temperature monitoring device in 
the firebox of the thermal oxidizer or incinerator, or in the duct 
immediately downstream of the firebox before any substantial heat 
exchange occurs. You must meet the requirements in paragraphs (b) and 
(d)(1)(i) through (vii) of this section for each temperature monitoring 
device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a minimum tolerance of 2.2 [deg]C 
or 0.75 percent of the temperature value, whichever is larger.
    (iii) Shield the temperature sensor system from electromagnetic 
interference and chemical contaminants.
    (iv) If a chart recorder is used, it must have a sensitivity in the 
minor division of at least 10 [deg]C.
    (v) Perform an electronic calibration at least semiannually 
according to the procedures in the manufacturer's owners manual. 
Following the electronic calibration, you must conduct a temperature 
sensor validation check in which a second or redundant temperature 
sensor placed nearby the process temperature sensor must yield a reading 
within 16.7 [deg]C of the process temperature sensor's reading.
    (vi) Conduct calibration and validation checks any time the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.

[[Page 580]]

    (vii) At least monthly, inspect all components for integrity and all 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (2) Before or during the performance test, you must conduct a 
performance evaluation of the combustion temperature monitoring system 
according to Sec. 63.8(e). Section 63.8(e) specifies the general 
requirements for continuous monitoring systems and requirements for 
notifications, the site-specific performance evaluation plan, conduct of 
the performance evaluation, and reporting of performance evaluation 
results.
    (3) During the performance test required by Sec. 63.5716, you must 
monitor and record the combustion temperature and determine the average 
combustion temperature for the three 1-hour test runs. This average 
temperature is the minimum operating limit for the thermal oxidizer.
    (4) Following the performance test, you must continuously monitor 
the combustion temperature and record the average combustion temperature 
no less frequently than every 15 minutes.
    (5) You must operate the incinerator or thermal oxidizer so that the 
average combustion temperature in any 3-hour period does not fall below 
the average combustion temperature recorded during the performance test.
    (6) If the average combustion temperature in any 3-hour period falls 
below the average combustion temperature recorded during the performance 
test, or if you fail to collect the minimum data specified in paragraph 
(d)(4) of this section, it is a deviation for the operating limit in 
Sec. 63.5715.
    (e) Other control devices. If you are using a control device other a 
thermal oxidizer, then you must comply with alternative monitoring 
requirements and operating limits approved by the Administrator under 
Sec. 63.8(f).
    (f) Emission capture system. For each enclosure in the emission 
capture system, you must comply with the requirements in paragraphs 
(f)(1) through (5) of this section.
    (1) You must install a device to measure and record either the flow 
rate or the static pressure in the duct from each enclosure to the add-
on control device.
    (2) You must install a device to measure and record the pressure 
drop across at least one opening in each enclosure.
    (3) Each flow measurement device must meet the requirements in 
paragraphs (b) and (f)(3)(i) through (iv) of this section.
    (i) Locate the flow sensor in a position that provides a 
representative flow measurement in the duct between each enclosure in 
the emission capture system and the add-on control device.
    (ii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iii) Conduct a flow sensor calibration check at least semiannually.
    (iv) At least monthly, inspect all components for integrity, all 
electrical connections for continuity, and all mechanical connections 
for leakage.
    (4) For each pressure measurement device, you must comply with the 
requirements in paragraphs (a) and (f)(4)(i) through (vii) of this 
section.
    (i) Locate each pressure drop sensor in or as close to a position 
that provides a representative measurement of the pressure drop across 
each enclosure opening you are monitoring.
    (ii) Locate each duct static pressure sensor in a position that 
provides a representative measurement of the static pressure in the duct 
between the enclosure and control device.
    (iii) Minimize or eliminate pulsating pressure, vibration, and 
internal and external corrosion.
    (iv) Check the pressure tap for plugging daily.
    (v) Use an inclined manometer with a measurement sensitivity of 
0.0004 millimeters mercury (mmHg) to check gauge calibration quarterly 
and transducer calibration monthly.
    (vi) Conduct calibration checks any time the sensor exceeds the 
manufacturer's specified maximum operating pressure range or install a 
new pressure sensor.
    (vii) At least monthly, inspect all components for integrity, all

you must meet the requirements of paragraphs (a) through (f) of this 
section.
    (a) Determine and record the organic HAP content (kilograms of 
organic HAP per kilogram of material, or weight fraction) of each 
aluminum wipedown solvent and aluminum coating (including primers, 
topcoats, clear coats, thinners, and activators). Use the methods in 
Sec. 63.5758 to determine organic HAP content.
    (b) Use the methods in Sec. 63.5758(b) to determine the solids 
content (liters of solids per liter of coating, or volume fraction) of 
each aluminum surface coating, including primers, topcoats, and clear 
coats. Keep records of the solids content.
    (c) Use the methods in Sec. 63.5758(c) to determine the density of 
each aluminum surface coating and wipedown solvent.
    (d) Compliance is based on a 12-month rolling average calculated at 
the end of every month. The first 12-month rolling-average period begins 
on the compliance date specified in Sec. 63.5695.
    (e) At the end of the twelfth month after your compliance date and 
at the end of every subsequent month, use the procedures in Sec. 63.5749 
to calculate the organic HAP from aluminum wipedown solvents per liter 
of coating solids, and use the procedures in Sec. 63.5752 to calculate 
the kilograms of organic HAP from aluminum coatings per liter of coating 
solids.
    (f) Keep records of the calculations used to determine compliance.
    (g) Approval of alternative means of demonstrating compliance. You 
may apply to the Administrator for permission to use an alternative 
means (such as an add-on control system) of limiting emissions from 
aluminum wipedown solvent and coating operations and demonstrating 
compliance with the emission limits in Sec. 63.5743(a).
    (1) The application must include the information listed in 
paragraphs (g)(1)(i) through (iii) of this section.
    (i) An engineering evaluation that compares the emissions using the 
alternative means to the emissions that would result from using the 
strategy specified in paragraphs (a) through (e) of this section. The 
engineering evaluation may include the results from an emission test 
that accurately measures the capture efficiency and control device 
efficiency achieved by the control system and the composition of the 
associated coatings so that the emissions comparison can be made.
    (ii) A proposed monitoring protocol that includes operating 
parameter values to be monitored for compliance and an explanation of 
how the operating parameter values will be established through a 
performance test.
    (iii) Details of appropriate recordkeeping and reporting procedures.
    (2) The Administrator will approve the alternative means of limiting 
emissions if the Administrator determines that HAP emissions will be no 
greater than if the source uses the procedures described in paragraphs 
(a) through (e) of this section to demonstrate compliance.
    (3) The Administrator's approval may specify operation, maintenance, 
and monitoring requirements to ensure that emissions from the regulated 
operations are no greater than those that would otherwise result from 
regulated operations in compliance with this subpart.

Sec. 63.5755  How do I demonstrate compliance with the aluminum recreational boat surface coating spray gun cleaning work practice standards?

    You must demonstrate compliance with the aluminum coating spray gun 
cleaning work practice standards by meeting the requirements of 
paragraph (a) or (b) of this section.
    (a) Demonstrate that solvents used to clean the aluminum coating 
spray guns contain no more than 5 percent organic HAP by weight by 
determining organic HAP content with the methods in Sec. 63.5758. Keep 
records of the organic HAP content determination.
    (b) For solvents containing more than 5 percent organic HAP by 
weight, comply with the requirements in paragraph (b)(1) or (b)(2), and 
paragraph (b)(3) of this section.
    (1) If you are using an enclosed spray gun cleaner, visually inspect 
it at least once per month to ensure that covers are in place and the 
covers have no visible gaps when the cleaner is not in use, and that 
there are no leaks from hoses or fittings.
    (2) If you are manually cleaning the gun or spraying solvent into a 
container that can be closed, visually inspect all solvent containers at 
least once per month to ensure that the containers have covers and the 
covers fit with no visible gaps.
    (3) Keep records of the monthly inspections and any repairs that are 
made to the enclosed gun cleaners or the covers.

         Methods for Determining Hazardous Air Pollutant Content



Sec. 63.5758  How do I determine the organic HAP content of materials?

    (a) Determine the organic HAP content for each material used. To 
determine the organic HAP content for each material used in your open 
molding resin and gel coat operations, carpet and fabric adhesive 
operations, or aluminum recreational boat surface coating operations, 
you must use one of the options in paragraphs (a)(1) through (6) of this 
section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of organic HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
determining organic HAP content by Method 311.
    (i) Include in the organic HAP total each organic HAP that is 
measured to be present at 0.1 percent by mass or more for Occupational 
Safety and Health Administration (OSHA)-defined carcinogens as specified 
in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or more for other 
compounds. For example, if toluene (not an OSHA carcinogen) is measured 
to be 0.5 percent

[[Page 586]]

of the material by mass, you do not need to include it in the organic 
HAP total. Express the mass fraction of each organic HAP you measure as 
a value truncated to four places after the decimal point (for example, 
0.1234).
    (ii) Calculate the total organic HAP content in the test material by 
adding up the individual organic HAP contents and truncating the result 
to three places after the decimal point (for example, 0.123).
    (2) Method 24 (appendix A to 40 CFR part 60). You may use Method 24 
to determine the mass fraction of non-aqueous volatile matter of 
aluminum coatings and use that value as a substitute for mass fraction 
of organic HAP.
    (3) ASTM D1259-85 (Standard Test Method for Nonvolatile Content of 
Resins). You may use ASTM D1259-85 (available for purchase from ASTM) to 
measure the mass fraction of volatile matter of resins and gel coats for 
open molding operations and use that value as a substitute for mass 
fraction of organic HAP.
    (4) Alternative method. You may use an alternative test method for 
determining mass fraction of organic HAP if you obtain prior approval by 
the Administrator. You must follow the procedure in Sec. 63.7(f) to 
submit an alternative test method for approval.
    (5) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) through (4) of this section, such 
as manufacturer's formulation data, according to paragraphs (a)(5)(i) 
through (iii) of this section.
    (i) Include in the organic HAP total each organic HAP that is 
present at 0.1 percent by mass or more for OSHA-defined carcinogens as 
specified in 29 CFR 1910.1200(d)(4) and at 1.0 percent by mass or more 
for other compounds. For example, if toluene (not an OSHA carcinogen) is 
0.5 percent of the material by mass, you do not have to include it in 
the organic HAP total.
    (ii) If the organic HAP content is provided by the material supplier 
or manufacturer as a range, then you must use the upper limit of the 
range for determining compliance. If a separate measurement of the total 
organic HAP content using the methods specified in paragraphs (a)(1) 
through (4) of this section exceeds the upper limit of the range of the 
total organic HAP content provided by the material supplier or 
manufacturer, then you must use the measured organic HAP content to 
determine compliance.
    (iii) If the organic HAP content is provided as a single value, you 
may assume the value is a manufacturing target value and actual organic 
HAP content may vary from the target value. If a separate measurement of 
the total organic HAP content using the methods specified in paragraphs 
(a)(1) through (4) of this section is less than 2 percentage points 
higher than the value for total organic HAP content provided by the 
material supplier or manufacturer, then you may use the provided value 
to demonstrate compliance. If the measured total organic HAP content 
exceeds the provided value by 2 percentage points or more, then you must 
use the measured organic HAP content to determine compliance.
    (6) Solvent blends. Solvent blends may be listed as single 
components for some regulated materials in certifications provided by 
manufacturers or suppliers. Solvent blends may contain organic HAP which 
must be counted toward the total organic HAP content of the materials. 
When detailed organic HAP content data for solvent blends are not 
available, you may use the values for organic HAP content that are 
listed in Table 5 or 6 to this subpart. You may use Table 6 to this 
subpart only if the solvent blends in the materials you use do not match 
any of the solvent blends in Table 5 to this subpart and you know only 
whether the blend is either aliphatic or aromatic. However, if test 
results indicate higher values than those listed in Table 5 or 6 to this 
subpart, then the test results must be used for determining compliance.
    (b) Determine the volume fraction solids in aluminum recreational 
boat surface coatings. To determine the volume fraction of coating 
solids (liters of coating solids per liter of coating) for each aluminum 
recreational boat surface coating, you must use one of the methods 
specified in paragraphs (b)(1) through

[[Page 587]]

(3) of this section. If the results obtained with paragraphs (b)(2) or 
(3) of this section do not to agree with those obtained according to 
paragraph (b)(1) of this section, you must use the results obtained with 
paragraph (b)(1) of this section to determine compliance.
    (1) ASTM Method D2697-86(1998) or D6093-97. You may use ASTM Method 
D2697-86(1998) or D6093-97 (available for purchase from ASTM) to 
determine the volume fraction of coating solids for each coating. Divide 
the nonvolatile volume percent obtained with the methods by 100 to 
calculate volume fraction of coating solids.
    (2) Information from the supplier or manufacturer of the material. 
You may obtain the volume fraction of coating solids for each coating 
from the supplier or manufacturer.
    (3) Calculation of volume fraction of coating solids. You may 
determine it using equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR22AU01.019

Where:

Solids=volume fraction of coating solids, liters coating solids per 
liter coating.
\m\volatiles=Total volatile matter content of the coating, including 
organic HAP, volatile organic compounds, water, and exempt compounds, 
determined according to Method 24 in appendix A of 40 CFR part 60, grams 
volatile matter per liter coating.
Davg=average density of volatile matter in the coating, grams 
volatile matter per liter volatile matter, determined from test results 
using ASTM Method D1475-90 (available for purchase from ASTM), 
information from the supplier or manufacturer of the material, or 
reference sources providing density or specific gravity data for pure 
materials. If there is disagreement between ASTM Method D1475-90 test 
results and other information sources, the test results will take 
precedence.

    (c) Determine the density of each aluminum recreational boat 
wipedown solvent and surface coating. Determine the density of all 
aluminum recreational boat wipedown solvents, surface coatings, 
thinners, and other additives from test results using ASTM Method D1475-
90, information from the supplier or manufacturer of the material, or 
reference sources providing density or specific gravity data for pure 
materials. If there is disagreement between ASTM Method D1475-90 test 
results and other information sources, you must use the test results to 
demonstrate compliance.

representative (for example, a State delegated the authority to carry 
out the provisions of this subpart).
    Aluminum recreational boat means any marine or freshwater 
recreational boat that has a hull or deck constructed primarily of 
aluminum. A recreational boat is a vessel which by design and 
construction is intended by the manufacturer to be operated primarily 
for pleasure, or to be leased, rented or chartered to another for the 
latter's pleasure (rather than for commercial or military purposes); and 
whose major structural components are fabricated and assembled in an 
indoor, production-line manufacturing plant or similar land-side 
operation and not in a dry dock, graving dock, or marine railway on the 
navigable waters of the United States.
    Aluminum recreational boat surface coating operation means the 
application of primers or top coats to aluminum recreational boats. It 
also includes the application of clear coats over top coats. Aluminum 
recreational boat surface coating operations do not include the

build or repair molds.
    Closed molding means any molding process in which pressure is used 
to distribute the resin through the reinforcing fabric placed between 
two mold surfaces to either saturate the fabric or fill the mold cavity. 
The pressure may be clamping pressure, fluid pressure, atmospheric 
pressure, or vacuum pressure used either alone or in combination. The 
mold surfaces may be rigid or flexible. Closed molding includes, but is 
not limited to, compression molding with sheet molding compound, 
infusion molding, resin injection molding (RIM), vacuum-assisted resin 
transfer molding (VARTM), resin transfer molding (RTM), and vacuum-
assisted compression molding. Processes in which a closed mold is used 
only to compact saturated fabric or remove air or excess resin from the 
fabric (such as in vacuum bagging), are not considered closed molding. 
Open molding steps, such as application of a gel coat or skin coat layer 
by conventional open molding prior to a closed molding process, are not 
closed molding.
    Cured resin and gel coat means resin or gel coat that has been 
polymerized and changed from a liquid to a solid.

pursuant to section 112(b) of the Clean Air Act.

[[Page 592]]

    Hazardous air pollutant content or HAP content means the amount of 
HAP contained in a regulated material at the time it is applied to the 
part being manufactured. If no HAP is added to a material as a thinner

Method, manufacturer's formulation data, or an equivalent method. For 
aluminum coatings, the HDS also documents the solids content by volume, 
determined from the manufacturer's formulation data. The purpose of the 
HDS is to help the affected source in showing compliance with the 
organic HAP content limits contained in this subpart. The HDS must state 
the maximum total organic HAP concentration, by weight, of the material. 
It must include any organic HAP concentrations equal to or greater than 
0.1 percent by weight for individual organic HAP that are carcinogens, 
as defined by the Occupational Safety and Health Administration Hazard 
Communication Standard (29 CFR part 1910), and 1.0 percent by weight for 
all other individual organic HAP, as formulated. The HDS must also 
include test conditions if EPA Method 311 is used for determining 
organic HAP content.
    Maximum achievable control technology (MACT) model point value means 
a number calculated for open molding operations that is a surrogate for 
emissions and is used to determine if your open molding operations are 
in compliance with the provisions of this subpart. The units for MACT 
model point values are kilograms of organic HAP per megagram of resin or 
gel coat applied.
    Manufacturer's certification means documentation furnished by a

Subpart WWWW--National Emissions Standards for Hazardous Air Pollutants: 
                Reinforced Plastic Composites Production

    Source: 68 FR 19402, Apr. 21, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5780  What is the purpose of this subpart?

    This subpart establishes national emissions standards for hazardous 
air pollutants (NESHAP) for reinforced plastic composites production. 
This subpart also establishes requirements to demonstrate initial and 
continuous compliance with the hazardous air pollutants (HAP) emissions 
standards.



Sec. 63.5785  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
reinforced plastic composites production facility that is located at a 
major source of HAP emissions. Reinforced plastic composites production 
is limited to operations in which reinforced and/or nonreinforced 
plastic composites or plastic molding compounds are manufactured using 
thermoset resins and/or gel coats that contain styrene to produce 
plastic composites. The resins and gel coats may also contain materials 
designed to enhance the chemical, physical, and/or thermal properties of 
the product. Reinforced plastic composites production also includes 
cleaning, mixing, HAP-containing materials storage, and repair 
operations associated with the production of plastic composites.
    (b) You are not subject to this subpart if your facility only 
repairs reinforced plastic composites. Repair includes the non-routine 
manufacture of individual components or parts intended to repair a 
larger item as defined in Sec. 63.5935
    (c) You are not subject to this subpart if your facility is a 
research and development facility as defined in section 112(c)(7) of the 
Clean Air Act (CAA).
    (d) You are not subject to this subpart if your reinforced plastic 
composites operations use less than 1.2 tons per year (tpy) of thermoset 
resins and gel coats that contain styrene combined.



Sec. 63.5787  What if I also manufacture fiberglass boats or boat parts?

    (a) If your source meets the applicability criteria in Sec. 63.5785, 
and is not subject to the Boat Manufacturing NESHAP (40 CFR part 63, 
subpart VVVV), you are subject to this subpart regardless of the final 
use of the parts you manufacture.
    (b) If your source is subject to 40 CFR part 63, subpart VVVV, and 
all the reinforced plastic composites you manufacture are used in 
manufacturing your boats, you are not subject to this subpart.
    (c) If you are subject to 40 CFR part 63, subpart VVVV, and meet the 
applicability criteria in Sec. 63.5785, and produce reinforced plastic 
composites that are not used in fiberglass boat manufacture at your 
facility, all operations associated with the manufacture of the 
reinforced plastic composites parts that are not used in fiberglass boat 
manufacture at your facility are subject to this subpart, except as 
noted in paragraph (d) of this section.
    (d) Facilities potentially subject to both this subpart and 40 CFR 
part 63, subpart VVVV may elect to have the operations in paragraph (c) 
of this section covered by 40 CFR part 63, subpart VVVV, in lieu of this 
subpart, if they

[[Page 600]]

can demonstrate that this will not result in any organic HAP emissions 
increase compared to complying with this subpart.



Sec. 63.5790  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new or existing affected source at 
reinforced plastic composites production facilities.
    (b) The affected source consists of all parts of your facility 
engaged in the following operations: Open molding, closed molding, 
centrifugal casting, continuous lamination, continuous casting, polymer 
casting, pultrusion, sheet molding compound (SMC) manufacturing, bulk 
molding compound (BMC) manufacturing, mixing, cleaning of equipment used 
in reinforced plastic composites manufacture, HAP-containing materials 
storage, and repair operations on parts you also manufacture.
    (c) The following operations are specifically excluded from any 
requirements in this subpart: Application of mold sealing and release 
agents, mold stripping and cleaning, repair of parts that you did not 
manufacture, including non-routine manufacturing of parts, personal 
activities that are not part of the manufacturing operations (such as 
hobby shops on military bases), prepreg materials as defined in 
Sec. 63.5935, non-gel coat surface coatings, repair or production 
materials that do not contain resin or gel coat, and research and 
development operations as defined in section 112(c)(7) of the CAA.
    (d) Production resins that must meet military specifications are 
allowed to meet the organic HAP limit contained in that specification. 
In order for this exemption to be used, you must supply to the 
permitting authority the specifications certified as accurate by the 
military procurement officer, and those specifications must state a 
requirement for a specific resin, or a specific resin HAP content. 
Production resins for which this exemption is used must be applied with 
nonatomizing resin application equipment unless you can demonstrate this 
is infeasible. You must keep a record of the resins for which you are 
using this exemption.



Sec. 63.5795  How do I know if my reinforced plastic composites production facility is a new affected source or an existing affected source?

    (a) A reinforced plastic composites production facility is a new 
affected source if it meets all the criteria in paragraphs (a)(1) and 
(2) of this section.
    (1) You commence construction of the affected source after August 2, 
2001.
    (2) You commence construction, and no other reinforced plastic 
composites production affected source exists at that site.
    (b) For the purposes of this subpart, an existing affected source is 
any affected source that is not a new affected source.

     Calculating Organic HAP Emissions Factors for Open Molding and 
                           Centrifugal Casting



Sec. 63.5796  What are the organic HAP emissions factor equations in Table 1 to this subpart, and how are they used in this subpart?

    Emissions factors are used in this subpart to determine compliance 
with certain organic HAP emissions limits in Tables 3 and 5 to this 
subpart. You may use the equations in Table 1 to this subpart to 
calculate your emissions factors. Equations are available for each open 
molding operation and centrifugal casting operation and have units of 
pounds of organic HAP emitted per ton (lb/ton) of resin or gel coat 
applied. These equations are intended to provide a method for you to 
demonstrate compliance without the need to conduct for a HAP emissions 
test. In lieu of these equations, you can elect to use site-specific 
organic HAP emissions factors to demonstrate compliance provided your 
site-specific organic HAP emissions factors are incorporated in the 
facility's air emissions permit and are based on actual facility HAP 
emissions test data. You may also use the organic HAP emissions factors 
calculated using the equations in Table 1 to this subpart, combined with 
resin and gel coat use data, to calculate your organic HAP emissions.

[[Page 601]]



63.5797  How do I determine the organic HAP content of my resins and gel coats?

    In order to determine the organic HAP content of resins and gel 
coats, you may rely on information provided by the material 
manufacturer, such as manufacturer's formulation data and material 
safety data sheets (MSDS), using the procedures specified in paragraphs 
(a) through (c) of this section, as applicable.
    (a) Include in the organic HAP total each organic HAP that is 
present at 0.1 percent by mass or more for Occupational Safety and 
Health Administration-defined carcinogens, as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other organic HAP 
compounds.
    (b) If the organic HAP content is provided by the material supplier 
or manufacturer as a range, you must use the upper limit of the range 
for determining compliance. If a separate measurement of the total 
organic HAP content, such as an analysis of the material by EPA Method 
311 of appendix A to 40 CFR part 63, exceeds the upper limit of the 
range of the total organic HAP content provided by the material supplier 
or manufacturer, then you must use the measured organic HAP content to 
determine compliance.
    (c) If the organic HAP content is provided as a single value, you 
may use that value to determine compliance. If a separate measurement of 
the total organic HAP content is made and is less than 2 percentage 
points higher than the value for total organic HAP content provided by 
the material supplier or manufacturer, then you still may use the 
provided value to demonstrate compliance. If the measured total organic 
HAP content exceeds the provided value by 2 percentage points or more, 
then you must use the measured organic HAP content to determine 
compliance.



Sec. 63.5798  What if I want to use, or I manufacture, an application technology (new or existing) whose organic HAP emissions characteristics are not 
          represented by the equations in Table 1 to this subpart?

    If you wish to use a resin or gel coat application technology (new 
or existing), whose emission characteristics are not represented by the 
equations in Table 1 to this subpart, you may use the procedures in 
paragraphs (a) or (b) of this section to establish an organic HAP 
emissions factor. This organic HAP emissions factor may then be used to 
determine compliance with the emission limits in this subpart, and to 
calculate facility organic HAP emissions.
    (a) Perform a organic HAP emissions test to determine a site-
specific organic HAP emissions factor using the test procedures in 
Sec. 63.5850.
    (b) Submit a petition to the Administrator for administrative review 
of this subpart. This petition must contain a description of the resin 
or gel coat application technology and supporting organic HAP emissions 
test data obtained using EPA test methods or their equivalent. The 
emission test data should be obtained using a range of resin or gel coat 
HAP contents to demonstrate the effectiveness of the technology under 
the different conditions, and to demonstrate that the technology will be 
effective at different sites. We will review the submitted data, and, if 
appropriate, update the equations in Table 1 to this subpart.



Sec. 63.5799  How do I calculate my facility's organic HAP emissions on a tpy basis for purposes of determining which paragraphs of Sec. 63.5805 apply?

    To calculate your facility's organic HAP emissions in tpy for 
purposes of determining which paragraphs in Sec. 63.5805 apply to you, 
you must use the procedures in either paragraph (a) of this section for 
new facilities prior to startup, or paragraph (b) of this section for 
existing facilities and new facilities after startup. You are not 
required to calculate or report emissions under this section if you are 
an existing facility that does not have centrifugal casting or 
continuous lamination/casting operations, or a new facility that does 
not have any of the following operations: Open molding, centrifugal 
casting, continuous lamination/casting, pultrusion, SMC and BMC 
manufacturing, and mixing. Emissions calculation and emission reporting 
procedures in other sections of this subpart still

[[Page 602]]

apply. Calculate organic HAP emissions prior to any add-on control 
device, and do not include organic HAP emissions from any resin or gel 
coat used in operations subject to the Boat Manufacturing NESHAP, 40 CFR 
part 63, subpart VVVV, or from the manufacture of large parts as defined 
in Sec. 63.5805(d)(2). For centrifugal casting operations at existing 
facilities, do not include any organic HAP emissions where resin or gel 
coat is applied to an open centrifugal mold using open molding 
application techniques. Table 1 and the Table 1 footnotes to this 
subpart present more information on calculating centrifugal casting 
organic HAP emissions. The timing and reporting of these calculations is 
discussed in paragraph (c) of this section.
    (a) For new facilities prior to startup, calculate a weighted 
average organic HAP emissions factor for the operations specified in 
Sec. 63.5805(b) and (d) on a lbs/ton of resin and gel coat basis. Base 
the weighted average on your projected operation for the 12 months 
subsequent to facility startup. Multiply the weighted average organic 
HAP emissions factor by projected resin use over the same period. You 
may calculate your organic HAP emissions factor based on the factors in 
Table 1 to this subpart, or you may use any HAP emissions factor 
approved by us, such as factors from the Compilation of Air Pollutant 
Emissions Factors, Volume I: Stationary Point and Area Sources (AP-42), 
or organic HAP emissions test data from similar facilities.
    (b) For existing facilities and new facilities after startup, you 
may use the procedures in either paragraph (b)(1) or (2) of this 
section. If the emission factors for an existing facility have changed 
over the period of time prior to their initial compliance date due to 
incorporation of pollution-prevention control techniques, existing 
facilities may base the average emission factor on their operations as 
they exist on the compliance date. If an existing facility has accepted 
an enforceable permit limit of less than 100 tons per year of HAP, and 
can demonstrate that they will operate at that level subsequent to the 
compliance date, the they can be deemed to be below the 100 tpy 
threshold.
    (1) Use a calculated emission factor. Calculate a weighted average 
organic HAP emissions factor on a lbs/ton of resin and gel coat basis. 
Base the weighted average on the prior 12 months of operation. Multiply 
the weighted average organic HAP emissions factor by resin and gel coat 
use over the same period. You may calculate this organic HAP emissions 
factor based on the equations in Table 1 to this subpart, or you may use 
any organic HAP emissions factor approved by us, such as factors from 
AP-42, or site-specific organic HAP emissions factors if they are 
supported by HAP emissions test data.
    (2) Conduct performance testing. Conduct performance testing using 
the test procedures in Sec. 63.5850 to determine a site-specific organic 
HAP emissions factor in units of lbs/ton of resin and gel coat used. 
Conduct the test under conditions expected to result in the highest 
possible organic HAP emissions. Multiply this factor by annual resin and 
gel coat use to determine annual organic HAP emissions. This calculation 
must be repeated and reported annually.
    (c) Existing facilities must initially perform this calculation 
based on their 12 months of operation prior to April 21, 2003, and 
include this information with their initial notification report. 
Existing facilities must repeat the calculation based on their resin and 
gel coat use in the 12 months prior to their initial compliance date, 
and submit this information with their initial compliance report. After 
their initial compliance date, existing and new facilities must 
recalculate organic HAP emissions over the 12-month period ending June 
30 or December 31, whichever date is the first date following their 
compliance date specified in Sec. 63.5800. Subsequent calculations 
should cover the periods in the semiannual compliance reports.

                     Compliance Dates and Standards



Sec. 63.5800  When do I have to comply with this subpart?

    You must comply with the standards in this subpart by the dates 
specified in Table 2 to this subpart. Facilities meeting a organic HAP 
emissions

[[Page 603]]

standard based on a 12-month rolling average must begin collecting data 
on the compliance date in order to demonstrate compliance.



Sec. 63.5805  What standards must I meet to comply with this subpart?

    You must meet the requirements of paragraphs (a) through (h) of this 
section that apply to you. You may elect to comply using any options to 
meeting these standards described in Secs. 63.5810 through 63.5830. Use 
the procedures in Sec. 63.5799 to determine if you meet or exceed the 
100 tpy threshold.
    (a) If you have an existing facility that does not have any 
centrifugal casting or continuous lamination/casting operations, or an 
existing facility that does have centrifugal casting or continuous 
lamination/casting operations, but the combination of all centrifugal 
casting and continuous lamination/casting operations emit less than 100 
tpy of HAP, you must meet the annual average organic HAP emissions 
limits in Table 3 to this subpart and the work practice standards in 
Table 4 to this subpart that apply to you.
    (b) If you have an existing facility that emits 100 tpy or more of 
HAP from the combination of all centrifugal casting and continuous 
lamination/casting operations, you must reduce the total organic HAP 
emissions from these operations by at least 95 percent by weight and 
meet any applicable work practice standards in Table 4 to this subpart 
that apply to you. Operations other than centrifugal casting, and 
continuous lamination/casting, must meet the requirements in Tables 3 
and 4 to this subpart. As an alternative to meeting 95 percent by 
weight, you may meet the organic HAP emissions limits in Table 5 to this 
subpart. If you have a continuous lamination/casting operation, that 
operation may alternatively meet a organic HAP emissions limit of 1.47 
lbs/ton of neat resin plus and neat gel coat plus applied. For 
centrifugal casting, the percent reduction requirement does not apply to 
organic HAP emissions that occur during resin application onto an open 
centrifugal casting mold using open molding application techniques.
    (c) If you have a new facility that emits less than 100 tpy of HAP 
from the combination of all open molding, centrifugal casting, 
continuous lamination/casting, pultrusion, SMC manufacturing, mixing, 
and BMC manufacturing, you must meet the annual average organic HAP 
emissions limits in Table 3 to this subpart and the work practice 
standards in Table 4 to this subpart that apply to you.
    (d)(1) Except as provided in paragraph (d)(2) of this section, if 
you have a new facility that emits 100 tpy or more of HAP from the 
combination of all open molding, centrifugal casting, continuous 
lamination/casting, pultrusion, SMC manufacturing, mixing, and BMC 
manufacturing, you must reduce the total organic HAP emissions from 
these operations by at least 95 percent by weight and meet any 
applicable work practice standards in Table 4 to this subpart that apply 
to you. As an alternative to meeting 95 percent by weight, you may meet 
the organic HAP emissions limits in Table 5 to this subpart. If you have 
a continuous lamination/casting operation, that operation may 
alternatively meet a organic HAP emissions limit of 1.47 lbs/ton of neat 
resin plus and neat gel coat plus applied.
    (2)(i) If your new facility manufactures large reinforced plastic 
composites parts using open molding or pultrusion operations, the 
specific open molding and pultrusion operations used to produce large 
parts are not required to reduce HAP emissions by 95 weight percent, but 
must meet the emission limits in Table 3 to this subpart.
    (ii) A large open molding part is defined as a part that, when the 
final finished part is enclosed in the smallest rectangular six-sided 
box into which the part can fit, the total interior volume of the box 
exceeds 250 cubic feet, or any interior sides of the box exceed 50 
square feet.
    (iii) A large pultruded part is a part that exceeds an outside 
perimeter of 24 inches or has more than 350 reinforcements.
    (e) If you have a new or existing facility subject to paragraphs (a) 
or (c) of this section at their initial compliance

[[Page 604]]

date, that subsequently meets or exceeds the 100 tpy threshold in any 
calendar year, you must notify your permitting authority in your 
compliance report. You may at the same time request a one-time exemption 
from the requirements of paragraphs (b) or (d) of this section in your 
compliance report if you can demonstrate all of the following:
    (1) The exceedance of the threshold was due to circumstances that 
will not to be repeated.
    (2) The average annual organic HAP emissions from the potentially 
affected operations for the last 3 years were below 100 tpy.
    (3) Projected organic HAP emissions for the next calendar year are 
below 100 tpy, based on projected resin and gel coat use and the HAP 
emission factors calculated according to the procedures in Sec. 63.5799
    (f) If you apply for an exemption in paragraph (e) of this section, 
and subsequently exceed the HAP emission thresholds specified in 
paragraphs (a) or (c) of this section over the next 12-month period, you 
must notify the permitting authority in your semi-annual report, the 
exemption is removed, and your facility must comply with paragraphs (b) 
or (d) of this section within 3 years from the time your organic HAP 
emissions first exceeded the threshold.
    (g) If you have repair operations subject to this subpart as defined 
in Sec. 63.5785, these repair operations must meet the requirements in 
Tables 3 and 4 to this subpart, and are not required to meet the 95 
percent organic HAP emissions reduction requirements in paragraphs (b) 
or (d) of this section.
    (h) If you use an add-on control device to comply with this subpart, 
you must meet all requirements contained in 40 CFR part 63, subpart SS.

                      Options for Meeting Standards



Sec. 63.5810  What are my options for meeting the standards for open molding and centrifugal casting operations at new and existing sources?

    You must use one of the following methods in paragraphs (a) through 
(d) of this section to meet the standards in Sec. 63.5805. When you are 
complying with an emission limit in Tables 3 or 5 to this subpart, you 
may use any control method that reduces organic HAP emissions, including 
reducing resin and gel coat organic HAP content, changing to nonatomized 
mechanical application, covered curing techniques, and routing part or 
all of your emissions to an add-on control. The necessary calculations 
must be completed within 30 days after the end of each month. You may 
switch between the compliance options in paragraphs (a) through (d) of 
this section. When you change to an option based on a 12-month rolling 
average, you must base the average on the previous 12 months of data 
calculated using the compliance option you are currently using unless 
you were using the compliant materials option in paragraph (d) of this 
section. In this case, you must immediately begin collecting resin and 
gel coat use data and demonstrate compliance 12 months after changing 
options.
    (a) Meet the individual organic HAP emissions limits for each 
operation. Demonstrate that you meet the individual organic HAP 
emissions limits for each open molding operation and for each 
centrifugal casting operation type in Tables 3, or 5 to this subpart 
that apply to you. This is done in two steps. First, determine an 
organic HAP factor for each individual resin and gel coat, application 
method, and control method you use in a particular operation. Second, 
calculate, for each particular operation type, a weighted average of 
those organic HAP emissions factors based on resin and gel coat use. 
Your calculated organic HAP emissions factor must either be at or below 
the applicable organic HAP emissions limit in Tables 3 or 5 to this 
subpart based on a 12-month rolling average. Use the procedures 
described in paragraphs (a)(1) through (3) of this section to calculate 
average organic HAP emissions factors for each of your operations.
    (1) Calculate your actual organic HAP emissions factor for each 
different process stream within each operation type. A process stream is 
defined as each individual combination of resin or gel coat, application 
technique, and control technique. Process streams within operations 
types are considered different from each other if any of the

[[Page 605]]

following three characteristics vary: The neat resin plus or neat gel 
coat plus organic HAP content, the application technique, or the control 
technique. You must calculate organic HAP emissions factors for each 
different process stream by using the appropriate equations in Table 1 
to this subpart for open molding and for centrifugal casting, or site-
specific organic HAP emissions factors discussed in Sec. 63.5796. If you 
want to use vapor suppressants to meet the organic HAP emissions limit 
for open molding, you must determine the vapor suppressant effectiveness 
by conducting testing according to the procedures specified of appendix 
A to subpart WWWW of 40 CFR part 63. If you want to use an add-on 
control device to meet the organic HAP emissions limit, you must 
determine the add-on control factor by conducting capture and control 
efficiency testing, using the procedures specified in Sec. 63.5850. The 
organic HAP emissions factor calculated from the equations in Table 1 to 
this subpart, or site-specific emissions factors, is multiplied by the 
add-on control factor to calculate the organic HAP emissions factor 
after control. Use Equation 1 of this section to calculate the add-on 
control factor used in the organic HAP emissions factor equations.

Where:

Percent Control Efficiency=a value calculated from organic HAP emissions 
test measurements made according to the requirements of Sec. 63.5850 to 
this subpart

    (2) Calculate your actual operation organic HAP emissions factor for 
the last 12 months for each open molding operation type and for each 
centrifugal casting operation type by calculating the weighted average 
of the individual process stream organic HAP emissions factors within 
each respective operation. To do this, sum the product of each 
individual organic HAP emissions factor calculated in paragraph (a)(1) 
of this section and the amount of neat resin plus and neat gel coat plus 
usage that correspond to the individual factors and divide the numerator 
by the total amount of neat resin plus and neat gel coat plus used in 
that operation type. Use Equation 2 of this section to calculate your 
actual organic HAP emissions factor for each open molding operation type 
and each centrifugal casting operation type.

emissions factor

    (3) Compare each organic HAP emissions factor calculated in 
paragraph (b)(2) of this section with its corresponding organic HAP 
emissions limit in Tables 3 or 5 to this subpart. If all emissions 
factors are equal to or

[[Page 606]]

less than their corresponding emission limits, then you are in 
compliance.
    (b) HAP Emissions factor averaging option. Demonstrate each month 
that you meet each weighted average of the organic HAP emissions limits 
in Tables 3 or 5 to this subpart that apply to you. When using this 
option, you must demonstrate compliance with the weighted average 
organic HAP emissions limit for all your open molding operations, and 
then separately demonstrate compliance with the weighted average organic 
HAP emissions limit for all your centrifugal casting operations. Open 
molding operations and centrifugal casting operations may not be 
averaged with each other.
    (1) Each month calculate the weighted average organic HAP emissions 
limit for all open molding operations and the weighted average organic 
HAP emissions limit for all centrifugal casting operations for your 
facility for the last 12-month period to determine the organic HAP 
emissions limit you must meet. To do this, multiply the individual 
organic HAP emissions limits in Tables 3 or 5 to this subpart for each 
open molding (centrifugal casting) operation type by the amount of neat 
resin plus or neat gel coat plus used in the last 12 months for each 
open molding (centrifugal casting) operation type, sum these results, 
and then divide this sum by the total amount of neat resin plus and neat 
gel coat plus used in open molding (centrifugal casting) over the last 
12 months. Use Equation 3 of this section to calculate the weighted 
average organic HAP emissions limit for all open molding operations and 
separately for all centrifugal casting operations.

Where:

ELi=organic HAP emissions limit for operation type i, lbs/ton 
from Tables 3, 5 or 7 to this subpart

    (2) Each month calculate your actual weighted average organic HAP 
emissions factor for open molding and centrifugal casting. To do this, 
multiply your actual open molding (centrifugal casting) operation 
organic HAP emissions factors and the amount of neat resin plus and neat 
gel coat plus used in each open molding (centrifugal casting) operation 
type, sum the results, and divide this sum by the total amount of neat 
resin plus and neat gel coat plus used in open molding (centrifugal 
casting) operations. You must calculate your actual individual HAP 
emissions factors for each operation type as described in paragraphs 
(a)(1) and (2) of this section. Use Equation 4 of this section to 
calculate your actual weighted average organic HAP emissions factor.

Actual Individual EFi=Actual organic HAP emissions factor for 
operation type i, lbs/ton

the last 12 calendar months for operation type i, tons
n=number of operations

    (3) Compare the values calculated in paragraphs (b)(1) and (2) of 
this section. If each 12-month rolling average organic HAP emissions 
factor is less than or equal to the corresponding 12-month rolling 
average organic HAP emissions limit, then you are in compliance.
    (c) If you have multiple operation types, meet the organic HAP 
emissions limit for one operation type, and use the same resin(s) for 
all operations of that resin type. If you have more than one operation 
type, you may meet the emission limit for one of those operations, and 
use the same resin(s) in all other open molding and centrifugal casting 
operations.
    (1) This option is limited to resins of the same type. The resin 
types for which this option may be used are noncorrosion-resistant, 
corrosion-resistant and/or high strength, and tooling.
    (2) For any combination of manual resin application, mechanical 
resin application, filament application, or centrifugal casting, you may 
elect to meet the organic HAP emissions limit for any one of these 
operations and use that operation's same resin in all of the resin 
operations listed in this paragraph. Table 7 to this subpart presents 
the possible combinations based on a facility selecting the application 
process that results in the highest allowable organic HAP content resin. 
If your resin organic HAP content is below the applicable values shown 
in Table 7 to this subpart, you are in compliance.
    (3) You may also use a weighted average organic HAP content for each 
operation described in paragraph (c)(2) of this section. Calculate the 
weighted average organic HAP content monthly. Use Equation 2 in 
Sec. 63.5810(a)(2) except substitute organic HAP content for organic HAP 
emissions factor. You are in compliance if the weighted average organic 
HAP content based on the last 12 months of resin use is less than or 
equal to the applicable organic HAP contents in Table 7 to this subpart.
    (4) You may simultaneously use the averaging provisions in paragraph 
(b) of this section to demonstrate compliance for any operations and/or 
resins you do not include in your compliance demonstrations is 
paragraphs (c)(2) and (3) of this section. However, any resins for which 
you claim compliance under the option in paragraphs (c)(2) and (3) of 
this section may not be included in any of the averaging calculations 
described in paragraphs (a) or (b) of this section used for resins for 
which you are not claiming compliance under this option.
    (d) Use resins and gel coats that do not exceed the maximum organic 
HAP contents shown in Table 3 to this subpart.



Sec. 63.5820  What are my options for meeting the standards for continuous lamination/casting operations?

    You must use one or more of the options in paragraphs (a) through 
(d) of this section to meet the standards in Sec. 63.5805. Use the 
calculation procedures in Secs. 63.5865 through 63.5890.
    (a) Compliant line option. Demonstrate that each continuous 
lamination line and each continuous casting line complies with the 
applicable standard.
    (b) Averaging option. Demonstrate that all continuous lamination and 
continuous casting lines combined, comply with the applicable standard.
    (c) Add-on control device option. If your operation must meet the 
58.5 weight percent organic HAP emissions reduction limit in Table 3 to 
this subpart, you have the option of demonstrating that you achieve 95 
percent reduction of all wet-out area organic HAP emissions.
    (d) Combination option. Use any combination of options in paragraphs 
(a) and (b) of this section or, for affected sources at existing 
facilities, any combination of options in paragraphs (a), (b), and (c) 
of this section (in which one or more lines meet the standards on their 
own, two or more lines averaged together meet the standards, and one or 
more lines have their wet-out areas controlled to a level of 95 
percent).

Sec. 63.5830  What are my options for meeting the standards for pultrusion operations subject to the 60 weight percent organic HAP emissions reductions 
          requirement?

    You must use one or more of the options in paragraphs (a) through 
(e) of this section to meet the 60 weight percent organic HAP emissions 
limit in Table 3 to this subpart, as required in Sec. 63.5805.
    (a) Achieve an overall reduction in organic HAP emissions of 60 
weight percent by capturing the organic HAP emissions and venting them 
to a control device or any combination of control devices. Conduct 
capture and destruction efficiency testing as specified in 63.5850 to 
this subpart to determine the percent organic HAP emissions reduction.
    (b) Design, install, and operate wet area enclosures and resin drip 
collection systems on pultrusion machines that meet the criteria in 
paragraphs (b)(1) through (10) of this section.
    (1) The enclosure must cover and enclose the open resin bath and the 
forming area in which reinforcements are pre-wet or wet-out and moving 
toward the die(s). The surfaces of the enclosure must be closed except 
for openings to allow material to enter and exit the enclosure.
    (2) For open bath pultrusion machines with a radio frequency pre-
heat unit, the enclosure must extend from the beginning of the resin 
bath to within 12.5 inches or less of the entrance of the radio 
frequency pre-heat unit. If the stock that is within 12.5 inches or less 
of the entrance to the radio frequency pre-heat unit has any drip, it 
must be enclosed. The stock exiting the radio frequency pre-heat unit is 
not required to be in an enclosure if the stock has no drip between the 
exit of the radio frequency pre-heat unit to within 0.5 inches of the 
entrance of the die.
    (3) For open bath pultrusion machines without a radio frequency pre-
heat unit, the enclosure must extend from the beginning of the resin 
bath to within 0.5 inches or less of the die entrance.
    (4) For pultrusion lines with a pre-wet area prior to direct die 
injection, the enclosure must extend from the point at which the resin 
is applied to the reinforcement to within 12.5 inches or less of the 
entrance of the die(s). If the stock that is within 12.5 inches or less 
of the entrance to the die has any drip, it must be enclosed.
    (5) The total open area of the enclosure must not exceed two times 
the cross sectional area of the puller window(s) and must comply with 
the requirements in paragraphs (b)(5)(i) through (iii) of this section.
    (i) All areas that are open need to be included in the total open 
area calculation with the exception of access panels, doors, and/or 
hatches that are part of the enclosure.
    (ii) The area that is displaced by entering reinforcement or exiting 
product is considered open.
    (iii) Areas that are covered by brush covers are considered closed.
    (6) Open areas for level control devices, monitoring devices, 
agitation shafts, and fill hoses must have no more than 1.0 inch 
clearance.
    (7) The access panels, doors, and/or hatches that are part of the 
enclosure must close tightly. Damaged access panels, doors, and/or 
hatches that do not close tightly must be replaced.
    (8) The enclosure may not be removed from the pultrusion line, and 
access panels, doors, and/or hatches that are part of the enclosure must 
remain closed whenever resin is in the bath, except for the time period 
discussed in paragraph (b)(9) of this section.
    (9) The maximum length of time the enclosure may be removed from the 
pultrusion line or the access panels, doors, and/or hatches and may be 
open, is 30 minutes per 8 hour shift, 45 minutes per 12 hour shift, or 
90 minutes per day if the machine is operated for 24 hours in a day. The 
time restrictions do not apply if the open doors or panels do not cause 
the limit of two times the puller window area to be exceeded. Facilities 
may average the times that access panels, doors, and/or hatches are open 
across all operating lines. In that case the average must not exceed the 
times shown in this paragraph (b)(9). All lines included in the average 
must have operated the entire time period being averaged.

[[Page 609]]

    (10) No fans, blowers, and/or air lines may be allowed within the 
enclosure. The enclosure must not be ventilated.
    (c) Use direct die injection pultrusion machines with resin drip 
collection systems that meet all the criteria specified in paragraphs 
(c)(1) through (3) of this section.
    (1) All the resin that is applied to the reinforcement is delivered 
directly to the die.
    (2) No exposed resin is present, except at the face of the die.
    (3) Resin drip is captured in closed piping and recycled directly to 
the resin injection chamber.
    (d) Use a preform injection system that meets the definition in 
Sec. 63.5935
    (e) Use any combination of options in paragraphs (a) through (d) of 
this section in which different pultrusion lines comply with different 
options described in paragraphs (a) through (d) of this section, and
    (1) Each individual pultrusion machine meets the 60 percent 
reduction requirement, or
    (2) The weighted average reduction based on resin throughout of all 
machines combined is 60 percent. For purposes of the average percent 
reduction calculation, wet area enclosures reduce organic HAP emissions 
by 60 percent, and direct die injection and preform injection reduce 
organic HAP emissions by 90 percent.

                     General Compliance Requirements



Sec. 63.5835  What are my general requirements for complying with this subpart?

    (a) You must be in compliance at all times with the work practice 
standards in Table 4 to this subpart, as well as the organic HAP 
emissions limits in Tables 3, or 5, or the organic HAP content limits in 
Table 7 to this subpart, as applicable, that you are meeting without the 
use of add-on controls.
    (b) You must be in compliance with all organic HAP emissions limits 
in this subpart that you meet using add-on controls, except during 
periods of startup, shutdown, and malfunction.
    (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).
    (d) You must develop and implement a written startup, shutdown, and 
malfunction plan according to the provisions in Sec. 63.6(e)(3) for any 
organic HAP emissions limits you meet using an add-on control.

               Testing and Initial Compliance Requirements



Sec. 63.5840  By what date must I conduct a performance test or other initial compliance demonstration?

    You must conduct performance tests, performance evaluations, design 
evaluations, capture efficiency testing, and other initial compliance 
demonstrations by the compliance date specified in Table 2 to this 
subpart, with three exceptions. Open molding and centrifugal casting 
operations that elect to meet a organic HAP emissions limit on a 12-
month rolling average must initiate collection of the required data on 
the compliance date, and demonstrate compliance 1 year after the 
compliance date. New sources that use add-on controls to initially meet 
compliance must demonstrate compliance within 180 days after their 
compliance date.



Sec. 63.5845  When must I conduct subsequentperformance tests?

    You must conduct a performance test every 5 years following the 
initial performance test for any standard you meet with an add-on 
control device.



Sec. 63.5850  How do I conduct performance tests, performance evaluations, and design evaluations?

    (a) If you are using any add-on controls to meet a organic HAP 
emissions limit in this subpart, you must conduct each performance test, 
performance evaluation, and design evaluation in 40 CFR part 63, subpart 
SS, that applies to you. The basic requirements for performance tests, 
performance evaluations, and design evaluations are presented in Table 6 
to this subpart.
    (b) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e)(1) and under the specific conditions that 
40 CFR part 63, subpart SS, specifies.
    (c) Each performance evaluation must be conducted according to the 
requirements in Sec. 63.8(e) as applicable and

[[Page 610]]

under the specific conditions that 40 CFR part 63, subpart SS, 
specifies.
    (d) You may not conduct performance tests or performance evaluations 
during periods of startup, shutdown, or malfunction, as specified in 
Sec. 63.7(e)(1).
    (e) You must conduct the control device performance test using the 
emission measurement methods specified in paragraphs (e)(1) through (5) 
of this section.
    (1) Use either Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select the sampling sites.
    (2) Use Method 2, 2A, 2C, 2D, 2F or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 18 of appendix A to 40 CFR part 60 to measure organic 
HAP emissions or use Method 25A of appendix A to 40 CFR part 60 to 
measure total gaseous organic emissions as a surrogate for total organic 
HAP emissions. If you use Method 25A, you must assume that all gaseous 
organic emissions measured as carbon are organic HAP emissions. If you 
use Method 18 and the number of organic HAP in the exhaust stream 
exceeds five, you must take into account the use of multiple 
chromatographic columns and analytical techniques to get an accurate 
measure of at least 90 percent of the total organic HAP mass emissions. 
Do not use Method 18 to measure organic HAP emissions from a combustion 
device; use instead Method 25A and assume that all gaseous organic mass 
emissions measured as carbon are organic HAP emissions.
    (4) You may use American Society for Testing and Materials (ASTM) 
D6420-99 (available for purchase from at least one of the following 
addresses: 100 Barr Harbor Drive, West Conshohocken, PA 19428-2959; or 
University Microfilms International, 300 North Zeeb Road, Ann Arbor, MI 
48106.) in lieu of Method 18 of 40 CFR part 60, appendix A, under the 
conditions specified in paragraphs (c)(4)(i) through (iii) of this 
section.
    (i) If the target compound(s) is listed in Section 1.1 of ASTM 
D6420-99 and the target concentration is between 150 parts per billion 
by volume and 100 parts per million by volume.
    (ii) If the target compound(s) is not listed in Section 1.1 of ASTM 
D6420-99, but is potentially detected by mass spectrometry, an 
additional system continuing calibration check after each run, as 
detailed in Section 10.5.3 of ASTM D6420-99, must be followed, met, 
documented, and submitted with the performance test report even if you 
do not use a moisture condenser or the compound is not considered 
soluble.
    (iii) If a minimum of one sample/analysis cycle is completed at 
least every 15 minutes.
    (5) Use the procedures in EPA Method 3B of appendix A to 40 CFR part 
60 to determine an oxygen correction factor if required by 
Sec. 63.997(e)(2)(iii)(C). You may use American Society of Mechanical 
Engineers (ASME) PTC 19-10-1981-Part 10 (available for purchase from 
ASME, P.O. Box 2900, 22 Law Drive, Fairfield, New Jersey, 07007-2900, or 
online at www.asme.org/catalog) as an alternative to EPA Method 3B of 
appendix A to 40 CFR part 60.
    (f) The control device performance test must consist of three runs 
and each run must last at least 1 hour. The production conditions during 
the test runs must represent normal production conditions with respect 
to the types of parts being made and material application methods. The 
production conditions during the test must also represent maximum 
potential emissions with respect to the organic HAP content of the 
materials being applied and the material application rates.
    (g) If you are using a concentrator/oxidizer control device, you 
must test the combined flow upstream of the concentrator, and the 
combined outlet flow from both the oxidizer and the concentrator to 
determine the overall control device efficiency. If the outlet flow from 
the concentrator and oxidizer are exhausted in separate stacks, you must 
test both stacks simultaneously with the inlet to the concentrator to 
determine the overall control device efficiency.
    (h) During the test, you must also monitor and record separately the 
amounts of production resin, tooling resin, pigmented gel coat, clear 
gel coat, and tooling gel coat applied inside the enclosure that is 
vented to the control device.

[[Page 611]]



Sec. 63.5855  What are my monitor installation and operation requirements?

    You must monitor and operate all add-on control devices according to 
the procedures in 40 CFR part 63, subpart SS.



Sec. 63.5860  How do I demonstrate initial compliance with the standards?

    (a) You demonstrate initial compliance with each organic HAP 
emissions standard in paragraphs (a) through (h) of Sec. 63.5805 that 
applies to you by using the procedures shown in Tables 8 and 9 to this 
subpart.
    (b) If using an add-on control device to demonstrate compliance, you 
must also establish each control device operating limit in 40 CFR part 
63, subpart SS, that applies to you.

 Emission Factor, Percent Reduction, and Capture Efficiency Calculation 
         Procedures for Continuous Lamination/Casting Operations



Sec. 63.5865  What data must I generate to demonstrate compliance with the standards for continuous lamination/casting operations?

    (a) For continuous lamination/casting affected sources complying 
with a percent reduction requirement, you must generate the data 
identified in Tables 10 and 11 to this subpart for each data requirement 
that applies to your facility.
    (b) For continuous lamination/casting affected sources complying 
with a lbs/ton limit, you must generate the data identified in Tables 11 
and 12 to this subpart for each data requirement that applies to your 
facility.



Sec. 63.5870  How do I calculate annual uncontrolled and controlled organic HAP emissions from my wet-out area(s) and from my oven(s) for continuous lamination/
          casting operations?

    To calculate your annual uncontrolled and controlled organic HAP 
emissions from your wet-out areas and from your ovens, you must develop 
uncontrolled and controlled wet-out area and uncontrolled and controlled 
oven organic HAP emissions estimation equations or factors to apply to 
each formula applied on each line, determine how much of each formula 
for each end product is applied each year on each line, and assign 
uncontrolled and controlled wet-out area and uncontrolled and controlled 
oven organic HAP emissions estimation equations or factors to each 
formula. You must determine the overall capture efficiency using the 
procedures in Sec. 63.5850 to this subpart.
    (a) To develop uncontrolled and controlled organic HAP emissions 
estimation equations and factors, you must, at a minimum, do the 
following, as specified in paragraphs (a)(1) through (6) of this 
section:
    (1) Identify each end product and the thickness of each end product 
produced on the line. Separate end products into the following end 
product groupings, as applicable: corrosion-resistant gel coated end 
products, noncorrosion-resistant gel coated end products, corrosion-
resistant nongel coated end products, and noncorrosion-resistant nongel 
coated end products. This step creates end product/thickness 
combinations.
    (2) Identify each formula used on the line to produce each end 
product/thickness combination. Identify the amount of each such formula 
applied per year. Rank each formula used to produce each end product/
thickness combination according to usage within each end product/
thickness combination.
    (3) For each end product/thickness combination being produced, 
select the formula with the highest usage rate for testing.
    (4) If not already selected, also select the worst-case formula 
(likely to be associated with the formula with the highest organic HAP 
content, type of HAP, application of gel coat, thin product, low line 
speed, higher resin table temperature) amongst all formulae. (You may 
use the results of the worst-case formula test for all formulae if 
desired to limit the amount of testing required.)
    (5) For each formula selected for testing, conduct at least one test 
(consisting of three runs). During the test, track information on 
organic HAP content and type of HAP, end product thickness, line speed, 
and resin temperature on the wet-out area table.
    (6) Using the test results, develop uncontrolled and controlled 
organic HAP

[[Page 612]]

emissions estimation equations (or factors) or series of equations (or 
factors) that best fit the results for estimating uncontrolled and 
controlled organic HAP emissions, taking into account the organic HAP 
content and type of HAP, end product thickness, line speed, and resin 
temperature on the wet-out area table.
    (b) In lieu of using the method specified in paragraph (a) of this 
section for developing uncontrolled and controlled organic HAP emissions 
estimation equations and factors, you may either method specified in 
paragraphs (b)(1) and (2) of this section, as applicable.
    (1) For either uncontrolled or controlled organic HAP emissions 
estimates, you may use previously established, facility-specific organic 
HAP emissions equations or factors, provided they allow estimation of 
both wet-out area and oven organic HAP emissions, where necessary, and 
have been approved by your permitting authority. If a previously 
established equation or factor is specific to the wet-out area only, or 
to the oven only, then you must develop the corresponding uncontrolled 
or controlled equation or factor for the other organic HAP emissions 
source.
    (2) For uncontrolled (controlled) organic HAP emissions estimates, 
you may use controlled (uncontrolled) organic HAP emissions estimates 
and control device destruction efficiency to calculate your uncontrolled 
(controlled) organic HAP emissions provided the control device 
destruction efficiency was calculated at the same time you collected the 
data to develop your facility's controlled (uncontrolled) organic HAP 
emissions estimation equations and factors.
    (c) Assign to each formula an uncontrolled organic HAP emissions 
estimation equation or factor based on the end product/thickness 
combination for which that formula is used.
    (d)(1) To calculate your annual uncontrolled organic HAP emissions 
from wet-out areas that do not have any capture and control and from 
wet-out areas that are captured by an enclosure but are vented to the 
atmosphere and not to a control device, multiply each formula's annual 
usage by its appropriate organic HAP emissions estimation equation or 
factor and sum the individual results.
    (2) To calculate your annual uncontrolled organic HAP emissions that 
escape from the enclosure on the wet-out area, multiply each formula's 
annual usage by its appropriate uncontrolled organic HAP emissions 
estimation equation or factor, sum the individual results, and multiply 
the summation by 1 minus the percent capture (expressed as a fraction).
    (3) To calculate your annual uncontrolled oven organic HAP 
emissions, multiply each formula's annual usage by its appropriate 
uncontrolled organic HAP emissions estimation equation or factor and sum 
the individual results.
    (4) To calculate your annual controlled organic HAP emissions, 
multiply each formula's annual usage by its appropriate organic HAP 
emissions estimation equation or factor and sum the individual results 
to obtain total annual controlled organic HAP emissions.
    (e) Where a facility is calculating both uncontrolled and controlled 
organic HAP emissions estimation equations and factors, you must test 
the same formulae. In addition, you must develop both sets of equations 
and factors from the same tests.



Sec. 63.5875  How do I determine the capture efficiency of the enclosure on my wet-out area and the capture efficiency of my oven(s) for continuous lamination/
          casting operations?

    (a) The capture efficiency of a wet-out area enclosure is assumed to 
be 100 percent if it meets the design and operation requirements for a 
permanent total enclosure (PTE) specified in EPA Method 204 of appendix 
M to 40 CFR part 51. If a PTE does not exist, then a temporary total 
enclosure must be constructed and verified using EPA Method 204, and 
capture efficiency testing must be determined using EPA Methods 204B 
through E of appendix M to 40 CFR part 51.
    (b) The capture efficiency of an oven is to be considered 100 
percent, provided the oven is operated under negative pressure.

[[Page 613]]



Sec. 63.5880  How do I determine how much neat resin plus is applied to the line and how much neat gel coat plus is applied to the line for continuous 
          lamination/casting operations?

    Use the following procedures to determine how much neat resin plus 
and neat gel coat plus is applied to the line each year.
    (a) Track formula usage by end product/thickness combinations.
    (b) Use in-house records to show usage. This may be either from 
automated systems or manual records.
    (c) Record daily the usage of each formula/end product combination 
on each line. This is to be recorded at the end of each run (i.e., when 
a changeover in formula or product is made) and at the end of each 
shift.
    (d) Sum the amounts from the daily records to calculate annual usage 
of each formula/end product combination by line.



Sec. 63.5885  How do I calculate percent reduction to demonstrate compliance for Continuous Lamination/Casting Operations?

    You may calculate percent reduction using any of the methods in 
paragraphs (a) through (d) of this section.
    (a) Compliant line option. If all of your wet-out areas have PTE 
that meet the requirements of EPA Method 204 of appendix M of 40 CFR 
part 51, and all of your wet-out area organic HAP emissions and oven 
organic HAP emissions are vented to an add-on control device, use 
Equation 1 of this section to demonstrate compliance. In all other 
situations, use Equation 2 of this section to demonstrate compliance.

                   Continuous Compliance Requirements



Sec. 63.5895  How do I monitor and collect data to demonstrate continuous compliance?

    (a) During production, you must collect and keep a record of data as 
indicated in 40 CFR part 63, subpart SS, if you are using an add-on 
control device.
    (b) You must monitor and collect data as specified in paragraphs 
(b)(1) through (4) 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 that 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 to this subpart, including data averages and calculations, 
or 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.
    (3) At all times, you must maintain necessary parts for routine 
repairs of the monitoring equipment.
    (4) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitoring equipment to provide 
valid data. Monitoring failures that are caused in part by poor 
maintenance or careless operation are not malfunctions.
    (c) You must collect and keep records of resin and gel coat use, 
organic HAP content, and operation where the resin is used if you are 
meeting any organic HAP emissions limits based on an organic HAP 
emissions limit in Tables 3 or 5 to this subpart. You must collect and 
keep records of resin and gel coat use, organic HAP content, and 
operation where the resin is used if you are meeting any organic HAP 
content limits in Table 7 to this subpart if you are averaging organic 
HAP contents. Resin use records may be based on purchase records if you 
can reasonably estimate how the resin is applied. The organic HAP 
content records may be based on MSDS or on resin specifications supplied 
by the resin supplier.
    (d) If you initially demonstrate that all resins and gel coats 
individually meet the applicable organic HAP emissions limits, or 
organic HAP content limits, then resin and gel coat use records are not 
required. However, you must include a statement in each compliance 
report that all resins and gel coats still meet the organic HAP limits 
for compliant resins and gel coats shown in Tables 3 or 7 to this 
subpart. If after this initial demonstration, you change to a higher 
organic HAP resin or gel coat, or increase the resin or gel coat organic 
HAP content, or change to a higher-emitting resin or gel coat 
application method, then you must either again demonstrate that all 
resins and gel coats still meet the applicable organic HAP emissions 
limits, or begin collecting resin and gel coat use records and calculate 
compliance on a 12-month rolling average.
    (e) For each of your pultrusion machines, you must record all times 
that wet area enclosures doors or covers are open and there is resin 
present in the resin bath.



Sec. 63.5900  How do I demonstrate continuous compliance with the standards?

    (a) You must demonstrate continuous compliance with each standard in 
Sec. 63.5805 that applies to you according to the methods specified in 
paragraphs (a)(1) through (3) of this section.
    (1) Compliance with organic HAP emissions limits for sources using 
add-on control devices is demonstrated following the procedures in 40 
CFR part 63, subpart SS. Sources using add-on controls may also use 
continuous emissions monitors to demonstrate continuous compliance as an 
alternative to control parameter monitoring.
    (2) Compliance with organic HAP emissions limits is demonstrated by 
maintaining a organic HAP emissions factor value less than or equal to 
the appropriate organic HAP emissions limit listed in Tables 3, or 5 to 
this subpart, on a 12-month rolling average, or by including in each 
compliance report a statement that all resins and gel

[[Page 616]]

coats meet the appropriate organic HAP emissions limits, as discussed in 
Sec. 63.5895(d).
    (3) Compliance with organic HAP content limits in Table 7 to this 
subpart is demonstrated by maintaining an average organic HAP content 
value less than or equal to the appropriate organic HAP contents listed 
in Table 7 to this subpart, on a 12-month rolling average, or by 
including in each compliance report a statement that all resins and gel 
coats individually meet the appropriate organic HAP content limits, as

retention of the relevant mechanical property compared to the same resin 
in unexposed condition. In addition, the exposed resin needs to 
demonstrate an increased retention of the relevant mechanical property 
of at least 20 percentage points when compared to a similarly exposed 
general-purpose resin. For example, if the general-purpose resin retains 
45 percent of the relevant property when tested as specified above, then 
a corrosion-resistant resin needs to retain at least 65 percent (45 
percent plus 20 percent) of its property. The general-purpose resin used

[[Page 623]]

containing reinforced plastic composite parts, that was originally 
manufactured in another facility. For a part to qualify as non-routine 
manufacture, it must be used for repair or replacement, and the 
manufacturing schedule must be based on the current or anticipated 
repair needs of the reinforced plastic composites product, or a product

reinforcements. Products produced by the polymer casting process include 
cultured marble products and polymer concrete.
    Preform Injection means a form of pultrusion where liquid resin is 
injected to saturate reinforcements in an enclosed system containing one

process, is collected in closed piping or covered troughs and then into 
a covered reservoir for recycle. Resin storage vessels, reservoirs, 
transfer systems, and collection systems are covered or shielded from 
the ambient air. Preform injection differs from direct die injection in 
that the injection chambers are not directly attached to the die.
    Prepreg materials means reinforcing fabric received precoated with 
resin which is usually cured through the addition of heat.
    Pultrusion means a continuous process for manufacturing composites 
that have a uniform cross-sectional shape. The process consists of 
pulling a fiber-reinforcing material through a resin impregnation 
chamber or bath and through a shaping die, where the resin is 
subsequently cured. There are several types of pultrusion equipment, 
such as open bath, resin injection, and direct die injection equipment.
    Repair means application of resin or gel coat to a part to correct a 
defect, where the resin or gel coat application occurs after the part 
has gone through all the steps of its typical production process, or the 
application occurs outside the normal production area. For purposes of 
this subpart, rerouting a part back through the normal production line, 
or part of the normal production line, is not considered repair.
    Resin transfer molding means a process for manufacturing composites 
whereby catalyzed resin is transferred or injected into a closed mold in 
which fiberglass reinforcement has been placed.
    Sheet molding compound (SMC) means a ready-to-mold putty-like 
molding compound that contains resin(s) processed into sheet form. The 
molding compound is sandwiched between a top and a bottom film. In 
addition to resin(s), it may also contain catalysts, fillers, chemical 
thickeners, mold release agents, reinforcements, and other ingredients. 
Sheet molding compound can be used in compression molding to manufacture 
reinforced plastic composites products.

    Shrinkage controlled resin means a resin that when promoted, 
catalyzed, and filled according to the resin manufacturer's 
recommendations demonstrates less than 0.3 percent linear shrinkage when 
tested according to ASTM D2566.
    SMC manufacturing means a process which involves the preparation of 
SMC.
    Tooling gel coat means a gel coat that is used to form the surface 
layer of molds. Tooling gel coats generally have high heat distortion 
temperatures, low shrinkage, high barcol hardness, and high dimensional 
stability.
    Tooling resin means a resin that is used to produce molds. Tooling 
resins generally have high heat distortion temperatures, low shrinkage, 
high barcol hardness, and high dimensional stability.
    Uncontrolled oven organic HAP emissions means those organic HAP 
emissions emitted from the oven through closed vent systems to the 
atmosphere and not to a control device. These organic HAP emissions do 
not include organic HAP emissions that may escape into the workplace 
through the opening of panels or doors on the ovens or other similar 
fugitive organic HAP emissions in the workplace.
    Uncontrolled wet-out area organic HAP emissions means any or all of 
the following: Organic HAP emissions from wet-out areas that do not have 
any capture and control, organic HAP emissions that escape from wet-out 
area enclosures, and organic HAP emissions from wet-out areas that are 
captured by an enclosure but are vented to the atmosphere and not to an 
add-on control device.
    Unfilled means that there has been no addition of fillers to a resin 
or that less than 10 percent of fillers by weight of the total resin 
plus filler mixture has been added.
    Vapor suppressant means an additive, typically a wax, that migrates 
to the surface of the resin during curing and forms a barrier to seal in 
the styrene and reduce styrene emissions.
    Vapor-suppressed resin means a resin containing a vapor suppressant 
added for the purpose of reducing styrene emissions during curing.
    White and off-white gel coat means a gel coat that contains 10 
percent of more titanium dioxide by weight.

Footnotes to Table 1
\1\ To obtain the organic HAP emissions factor value for an operation with an add-on control device multiply the
  EF above by the add-on control factor calculated using Equation 1 of Sec.  63.5810. The organic HAP emissions
  factors have units of lbs of organic HAP per ton of resin or gel coat applied.
\2\ Percent HAP means total weight percent of organic HAP (styrene, methyl methacrylate, and any other organic
  HAP) in the resin or gel coat prior to the addition of fillers, catalyst, and promoters. Input the percent HAP
  as a decimal, i.e. 33 percent HAP should be input as 0.33, not 33.
\3\ The VSE factor means the percent reduction in organic HAP emissions expressed as a decimal measured by the
  VSE test method of appendix A to this subpart.
\4\ This equation is based on a organic HAP emissions factor equation developed for mechanical atomized
  controlled spray. It may only be used for automated or robotic spray systems with atomized spray. All spray
  operations using hand held spray guns must use the appropriate mechanical atomized or mechanical nonatomized
  organic HAP emissions factor equation. Automated or robotic spray systems using nonatomized spray should use
  the appropriate nonatomized mechanical resin application equation.
\5\ Applies only to filament application using an open resin bath. If resin is applied manually or with a spray
  gun, use the appropriate manual or mechanical application organic HAP emissions factor equation.
\6\ Do not use this equation for determining compliance with emission limits in Tables 3 or 5 to this subpart.
  To determine compliance with emission limits you must treat all gel coat as if it were applied as part of your
  gel coat spray application operations. If you apply gel coat by manual techniques only, you must treat the gel
  coat as if it were applied with atomized spray and use Equation 1.f. to determine compliance with the
  appropriate emission limits in Tables 3 or 5 to this subpart. To estimate emissions from manually applied gel
  coat, you may either include the gel coat quantities you apply manually with the quantities applied using
  spray, or use this equation to estimate emissions from the manually applied portion of your gel coat.

[[Page 626]]

 
\7\ These equations are for centrifugal casting operations where the mold is vented during spinning. Centrifugal
  casting operations where the mold is completely sealed after resin injection are considered to be closed
  molding operations.
\8\ If a centrifugal casting operation uses mechanical or manual resin application techniques to apply resin to
  an open centrifugal casting mold, use the appropriate open molding equation with covered cure and no rollout
  to determine an emission factor for operations prior to the closing of the centrifugal casting mold. If the
  closed centrifugal casting mold is vented during spinning, use the appropriate centrifugal casting equation to
  calculate an emission factor for the portion of the process where spinning and cure occur. If a centrifugal
  casting operation uses mechanical or manual resin application techniques to apply resin to an open centrifugal
  casting mold, and the mold is then closed and is not vented, treat the entire operation as open molding with
  covered cure and no rollout to determine emission factors.

Footnotes to Table 3
1 Organic HAP emissions limits for open molding and centrifugal casting are expressed as lb/ton. You must be at
  or below these values based on a 12-month rolling average.
2 A compliant resin or gel coat means that if its organic HAP content is used to calculate an organic HAP
  emissions factor, the factor calculated does not exceed the appropriate organic HAP emissions limit shown in
  the table.
3 These limits are for spray application of gel coat. Manual gel coat application must be included as part of
  spray gel coat application for compliance purposes using the same organic HAP emissions factor equation and
  organic HAP emissions limit. If you only apply gel coat with manual application, treat the manually applied
  gel coat as if it were applied with atomized spray for compliance determinations.
4 Centrifugal casting operations where the mold is not vented during spinning and cure are considered to be
  closed molding and are not subject to any emissions limit. Centrifugal casting operations where the mold is
  not vented during spinning and cure, and the resin is applied to the open centrifugal casting mold using
  mechanical or manual open molding resin application techniques are considered to be open molding operations
  and the appropriate open molding emission limits apply.
5 Centrifugal casting operations where the mold is vented during spinning and the resin is applied to the open
  centrifugal casting mold using mechanical or manual open molding resin application techniques, use the
  appropriate centrifugal casting emission limit to determine compliance. Calculate your emission factor using
  the appropriate centrifugal casting emission factor in Table 1 to this subpart, or a site specific emission
  factor as discussed in Sec.  63.5796.
6 Pultrusion machines that produce parts with 1000 or more reinforcements and a cross sectional area of 60
  inches or more are not subject to this requirement. Their requirement is the work practice of air flow
  management which is described in Table 4 to this subpart.

9. SMC Manufacturing............  N/A................  2.4 lb/ton.
------------------------------------------------------------------------
\1\ Organic HAP emissions limits for open molding and centrifugal
  casting expressed as lb/ton are calculated using the equations shown
  in Table 1 to this subpart. You must be at or below these values based
  on a 12-month rolling average.
\2\ These limits are for spray application of gel coat. Manual gel coat
  application must be included as part of spray gel coat application for
  compliance purposes using the same organic HAP emissions factor
  equation and organic HAP emissions limit. If you only apply gel coat
  with manual application, treat the manually applied gel coat as if it
  were applied with atomized spray for compliance determinations.
\3\ Centrifugal casting operations where the mold is not vented during
  spinning and cure are considered to be closed molding and are not
  subject to any emissions limit. Centrifugal casting operations where
  the mold is not vented during spinning and cure, and the resin is
  applied to the open centrifugal casting mold using mechanical or
  manual open molding resin application techniques are considered to be
  open molding operations and the appropriate open molding emission
  limits apply.
\4\ Centrifugal casting operations where the mold is vented during
  spinning and the resin is applied to the open centrifugal casting mold
  using mechanical or manual open molding resin application techniques,
  use the appropriate centrifugal casting emission limit to determine
  compliance. Calculate your emission factor using the appropriate
  centrifugal casting emission factor in Table 1 to this subpart, or a
  site specific emission factor as discussed in Sec.  63.5796.

                        1. Scope and Application

    1.1 Applicability. If a facility is using vapor suppressants to 
reduce hazardous air pollutant (HAP) emissions, the organic HAP emission 
factor equations in Table 1 to this subpart require that the vapor 
suppressant effectiveness factor be determined. The vapor suppressant 
effectiveness factor is then used as one of the inputs into the 
appropriate organic HAP emission factor equation. The vapor suppressant 
effectiveness factor test is not intended to quantify overall volatile 
emissions from a resin, nor to be used as a stand-alone test for 
emissions determination. This test is designed to evaluate the 
performance of film forming vapor suppressant resin additives. The 
results of this test are used only in combination with the organic HAP 
emissions factor equations in Table 1 to this subpart to generate 
emission factors.
    1.1.1 The open molding process consists of application of resin and 
reinforcements to the mold surface, followed by a manual rollout process 
to consolidate the laminate, and the curing stage where the laminate 
surface is not disturbed. Emission studies have shown that approximately 
50 percent to 55 percent of the emissions occur while the resin is being 
applied to the mold. Vapor suppressants have little effect during this 
portion of the lamination process, but can have a significant effect 
during the curing stage. Therefore, if a suppressant is 100 percent 
effective, the overall emissions from the process would be reduced by 45 
percent to 50 percent, representing the emissions generated during the 
curing stage. In actual practice, vapor suppressant effectiveness will 
be less than 100 percent and the test results determine the specific 
effectiveness in terms of the vapor suppressant effectiveness factor. 
This factor represents the effectiveness of a specific combination of 
suppressant additive and resin formulation.
    1.1.2 A resin manufacturer may supply a molder with a vapor-
suppressed resin, and employ this test to provide the molder with the 
vapor suppressant effectiveness factor for that combination of resin and 
vapor suppressant. The factor qualifies the effectiveness of the vapor 
suppressant when the resin is tested in the specific formulation 
supplied to the molder. The addition of fillers or other diluents by the 
molder may impact the effectiveness of the vapor suppressant. The 
formulation, including resin/glass ratio and filler content, used in the 
test should be similar to the formulation to be used in production. The 
premise of this method is to compare laminate samples made with vapor 
suppressant additive and made without the additive. The difference in 
emissions between the two yields the vapor suppressant effectiveness 
factor.
    1.1.3 The method uses a mass balance determination to establish the 
relative loss of the volatile component from unsaturated polyester or 
vinyl ester resins, with and without vapor suppressant additives. The 
effectiveness of a specific vapor suppressant and resin mixture is 
determined by comparing the relative volatile weight losses from vapor 
suppressed and non-suppressed resins. The volatile species are not 
separately analyzed. While the species contained in the volatile 
component are not determined, an extended listing of potential monomer 
that may be contained in unsaturated polyester or vinyl ester resins is 
provided in Table 1.1. However, most polyester and vinyl ester resin 
formulations presently used by the composites industry only contain 
styrene monomer.

                          2. Summary of Method

    2.1 Differences in specific resin and suppressant additive chemistry 
affect the performance of a vapor suppressant. The purpose of this 
method is to quantify the effectiveness of a specific combination of 
vapor suppressant and unsaturated polyester or vinyl ester resin as they 
are to be used in production. This comparative test quantifies the loss 
of volatiles from a fiberglass reinforced laminate during the roll-out 
and curing emission phases, for resins formulated with and without a 
suppressant additive. A criterion for this method is the testing of a 
non-vapor suppressed resin system and testing the same resin with a 
vapor suppressant. The two resins are as identical as possible with the 
exception of the addition of the suppressant to one. The exact 
formulation used for the test will be determined by the in-use 
production requirements. Each formulation of resin, glass, fillers, and 
additives is developed to meet particular customer and or performance 
specifications.
    2.2 The result of this test is used as an input factor in the 
organic HAP emissions factor equations in Table 1 to this subpart, which 
allows these equations to predict emissions from a specific combination 
of

[[Page 643]]

resin and suppressant. This test does not provide an emission rate for 
the entire lamination process.

                           11. Test Procedure

    11.1 Test Set-up.
    11.1.1 The laboratory balance is located in an enclosure to prevent 
fluctuations in balance readings due to localized air movement. The 
front of enclosure is open to permit work activity, but positioned so 
that local airflow will not effect balance readings. The ambient 
temperature is determined by suspending the thermometer at a point 
inside the enclosure.
    11.1.2 The bottom of the aluminum pan is covered with the Mylar 
film. The film is held in position with tape or by friction between the 
pan and the film.
    11.1.3 The resin and pan are brought to room temperature. This test 
temperature must be between 70 [deg]F and 80 [deg]F. The testing 
temperature cannot vary more than [plusmn]2 [deg]F during the 
measurement of test runs. Temperature shall be recorded at the same time 
weight is recorded on suppressed and non-suppressed test data sheets, 
shown in Table 17.1.
    11.1.4 The relative humidity may not change more than [plusmn]15 
percent during the test runs. This is determined by recording the 
relative humidity in the vicinity of the test chamber at the beginning 
and end of an individual test run. This data is recorded on the test 
data sheets shown in Table 17.1.
    11.1.5 Two plies of nominal 1.5 oz/ft\2\ chopped strand mat (CSM) 
are cut into a square or rectangle with the minimum surface area of 60 
square inches (i.e. a square with a side dimension of 7.75 inches).
    11.1.6 The appropriate resin application roller is readily 
available.
    11.2 Resin Gel Time/Initiator Percentage
    11.2.1 Previous testing has indicated that resin gel time influences 
the emissions from composite production. The testing indicated that 
longer the gel times led to higher emissions. There are a number of 
factors that influence gel time including initiator type, initiator 
brand, initiator level, temperature and resin additives. Under actual 
usage conditions a molder will adjust the initiator to meet a gel time 
requirement. In this test procedure, the vapor suppressed and non-vapor 
suppressed resin systems will be adjusted to the same gel time by 
selecting the appropriate initiator level for each.
    11.2.2 All test runs within a test will be processed in a manner 
that produces the same resin gel time [plusmn]2 minutes. To facilitate 
the resin mixing procedure, master batches of resin and resin plus vapor 
suppressant of resin are prepared. These resin master batches will have 
all of the required ingredients except initiator; this includes filler 
for filled systems. The gel times for the tests are conducted using the 
master batch and adjustments to meet gel time requirements shall be made 
to the master batch before emission testing is conducted. Test 
temperatures must be maintained within the required range, during gel 
time testing. Further gel time testing is not required after the non-
vapor suppressed and vapor suppressed master batches are established 
with gel times within [plusmn]2 minutes. A sufficient quantity of each 
resin should be prepared to allow for additional test specimens in the 
event one or more test fails to meet the data acceptance criteria 
discussed in Section 11.5 and shown in Table 17.2.
    11.2.3 The specific brand of initiator and the nominal percentage 
level recommended by the resin manufacturer will be indicated on the 
resin certificate of analysis \15\; or, if a unique gel time is required 
in a production laminate, initiator brand and percentage will be 
determined by that specific requirement.
    11.2.4 Examples:
    11.2.4.1 The resin for a test run is specified as having a 15-minute 
cup gel time at 77 [deg]F using Brand X initiator at 1.5 percent by 
weight. The non-suppressed control resin has a 15-minute gel time. The 
suppressed resin has a gel time of 17-minutes. An initiator level of 1.5 
percent would be selected for the both the non-suppressed and the 
suppressed test samples.
    11.2.4.2 Based on a specific production requirement, a resin is 
processed in production using 2.25 percent of Brand Y initiator, which 
produces a 20-minute gel time. This initiator at level of 2.25 percent 
produces a 20 minute gel time for the non-suppressed control resin, but 
yields a 25-minute gel time for the suppressed resin sample. The 
suppressed resin is retested at 2.50 percent initiator and produces a 
21-minute gel time. The initiator levels of 2.25 percent and 2.50 
percent respectively would yield gel times within [plusmn]2 minutes.

    11.3 Test Run Procedure for Unfilled Resin (see the data sheet shown 
in Table 17.1).
    11.3.1 The insulating board is placed on the balance.
    11.3.2 The aluminum pan with attached Mylar film is placed on the 
balance, and the balance is tared (weight reading set to zero with the 
plate on the balance.)
    11.3.3 Place two plies of 1.5 oz. CSM on the balance and record the 
weight (glass weight).
    11.3.4 The resin beaker and stirring rod are put on the second 
balance and tared.
    11.3.5 The required resin weight and initiator weight are calculated 
(refer to calculation formulas in 12.2).
    11.3.6 The disposable resin application roller is placed on the edge 
of the plate.
    11.3.7 The balance is tared, with the aluminum pan, Mylar film, 
glass mat, and resin application roller on the balance pan.
    11.3.8 Resin is weighed into a beaker, as calculated, using the 
second balance. The mixing stick should be tared with the beaker weight.
    11.3.9 Initiator is weighed into the resin, as calculated, using an 
eyedropper or a pipette, and the combination is mixed.
    11.3.10 Initiated resin is poured on chopped strand mat in a pe-
determined pattern (see Figure 11.6).
    11.3.11 A stopwatch is started from zero.
    11.3.12 The initial laminate weight is recorded.
    11.3.13 The plate is removed from balance to enable roll-out of the 
laminate.
    11.3.14 The wet laminate is rolled with the resin application roller 
to completely distribute the resin, saturate the chopped strand mat, and 
eliminate air voids. Roll-out time should be in the range of 2 to 3\16\ 
minutes and vary less than [plusmn]10 percent of the average time 
required for the complete set of six suppressed and six non-suppressed 
runs.
    11.3.15 Record the rollout end time (time from start to completion 
of rollout).
    11.3.16 Place the resin application roller on the edge of the plate 
when rollout is completed.
    11.3.17 Place the plate back on the balance pan. Immediately record 
the weight.
    11.3.18 For the first test in a series of six tests, weight is 
recorded every 5-minute interval (suppressed and non-suppressed). The 
end of the test occurs when three consecutive equal weights are recorded 
or a weight gain is observed (the last weight before the increased 
weight is the end of test weight). For the remaining five tests in the 
series, after the initial weights are taken, the next weight is recorded 
30 minutes before the end of the test, as suggested by the results from 
the first test. It is likely that the time to reach the end point of a 
suppressed resin test will be shorter than the time required to complete 
a non-suppressed test. Therefore, the time to start taking data manually 
may be different for suppressed and non-suppressed resins.
    11.4 Test Run Procedures for Filled Resin Systems \17\ Note that the 
procedure for filled systems differs from the procedure for unfilled 
systems. With filled systems, resin is applied to one ply of the CSM and 
the second ply is placed on top of the resin.
    11.4.1 The insulating board is placed on the balance.
    11.4.2 The aluminum pan with attached Mylar film is placed on the 
balance, and the balance is tared (weight reading set to zero with the 
plate on the balance.)
    11.4.3 Place two plies of 1.5 oz. CSM on the balance and record the 
weight (glass weight).
    11.4.4 Remove the top ply of fiberglass and record its weight 
(weight of 1st layer of glass).
    11.4.5 The required resin weight and initiator weight are calculated 
(refer to calculation formulas in 12.2). Calculate the weight of filled 
resin and initiator based on the 2 layers of fiberglass.
    11.4.6 The resin beaker and stirring rod are put on the second 
balance and tared.
    11.4.7 A disposable resin application roller is placed on the edge 
of the plate.
    11.4.8 The balance is tared, with the aluminum pan, Mylar film, 
glass mat, and resin application roller on the balance pan.
    11.4.9 Resin is weighed into the beaker, as calculated, using the 
second balance. The mixing stick should be tared with the beaker weight.
    11.4.10 Initiator is weighed into the resin, as calculated, using an 
eyedropper or a pipette, and the combination is mixed.
    11.4.11 Initiated resin is poured on the single ply of CSM in a pre-
determined pattern. Refer to Figure 11.6.
    11.4.12 A stopwatch is started from zero.
    11.4.13 Record the weight of the resin ans single ply of CSM 
(L1). The initial laminate weight equals L1 plus 
the weight of second glass layer.
    11.4.14 Replace the second layer of fiberglass.
    11.4.15 Remove the plate from the balance to allow roll-out of the 
laminate.
    11.4.16 Roll the wet laminate with the resin application roller to 
completely distribute the resin, saturate the chopped strand mat, and 
eliminate air voids. Roll-out time should be in the range of 2 to 3\16\ 
minutes and vary less than [plusmn] 10 percent of the average time 
required for the complete set of six suppressed and six non-suppressed 
runs.
    11.4.17 Record the roll-out end time (time from start to completion 
of rollout).
    11.4.18 Place the resin application roller on the edge of the plate 
when rollout is completed.
    11.4.19 Place the plate back on the balance pan. The initial weight 
is recorded immediately.

[[Page 646]]

    11.4.20 For the first test run in a series of six, weight is 
recorded at every 5-minute interval (suppressed and non-suppressed). The 
end of the test occurs when three consecutive equal weights are recorded 
or a weight gain is observed (the last weight before the increased 
weight is the end of test weight). For the remaining five tests in the 
series, after the initial weights are taken, the next weight is recorded 
30 minutes before the end of the test, as suggested by the results from 
the first test. It is likely that the time to reach the end point of a 
suppressed resin test will be shorter than the time required to complete 
a non-suppressed test. Therefore, the time to start taking data manually 
may be different for suppressed and non-suppressed resins.
    11.5 Data Acceptance Criteria:
    11.5.1 A test set is designed as twelve individual test runs using 
the same resin, initiator, and gel time, six of the test runs use the 
resin non-vapor suppressed and the other six use it vapor suppressed.
    11.5.2 If a test run falls outside any of the time, temperature, 
weight or humidity variation requirements, it must be discarded and run 
again.
    11.5.3 The laminate roll out time for each individual test run must 
vary less than [plusmn] 10 percent of the average time required for the 
complete set of six suppressed and six non-suppressed runs.
    11.5.4 Test temperature for each test run must be maintained within 
[plusmn]2 [deg]F and the average must be between 70[deg] and 80 [deg]F. 
Refer to 11.1.3.
    11.5.5 The difference in the amount of resin for each run must be 
within [plusmn]10 percent of the average weight for the complete set of 
six suppressed and six non-suppressed runs.
    11.5.6 The relative humidity from each test run must be within 
[plusmn]15 percent of the average humidity for the complete set of six 
suppressed and six non-suppressed tests. Refer to 11.1.4
    11.5.7 The glass content for each test set must be within [plusmn]10 
percent of the average resin-to-/glass ratio for the complete set of six 
suppressed and six non-suppressed runs. Refer to 12.2).
    11.5.8 The filler content for each test of a test set must be within 
[plusmn]5 percent of the average filler content for the complete set of 
six suppressed and six non-suppressed runs. Refer to 12.2.
    11.6 Resin Application Pour Pattern:
    11.6.1 To facilitate the distribution of resin across the chopped 
strand mat, and to provide consistency from test to test, a uniform pour 
pattern should be used. A typical pour pattern is shown below:

[GRAPHIC] [TIFF OMITTED] TR21AP03.009

    11.6.2 The resin is to be evenly distributed across the entire 
surface of the chopped strand mat using the resin application roller to 
achieve a wet look across the surface of the laminate. Pushing excess 
resin off the reinforcement and onto the Mylar sheet should be avoided. 
No resin is to be pushed more than \1/2\ inch beyond the edge of the 
glass mat. If excess resin is pushed further from the glass mat, it will 
void the test run. As

[[Page 647]]

part of this process, typical visible air voids are to be eliminated by 
the rollout process. If the pour pattern is different from the above, it 
must be recorded and attached to test data sheet 17.1.

                   12. Data Analysis and Calculations

    12.1 Data Analysis:
    This test method requires a simple mass balance calculation, no 
special data analysis is necessary.
    12.2 Calculations:
    12.2.1 The target glass content (percent) for unfilled resin systems 
is determined from the specific production parameters being evaluated. 
In absence of any specific production requirements the target may be set 
at the tester's discretion.
    12.2.2 Glass content determination (expressed as a per cent):

% Glass = Glass wt(g)/(Glass wt(g) + Resin weight (g))

    12.2.3 Weight of resin required:
    Resin weight required = (Glass wt (g)/% glass)--Glass wt (g)
    12.2.4 Filled resin formulation determination for filled resin 
systems (e.g. 30 percent filler by weight for a particulate 
filler, or 1 percent by weight for a lightweight filler, such 
as hollow microspheres):

% Resin content = resin
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))
% Glass content = glass
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))
Filler content = filler
weight(g)/(resin weight(g) + glass
weight(g) + filler weight(g))

    12.2.5 Initiator weight determination:

Initiator weight (g) = Resin weight(g) x Initiator %

    12.2.6 Emission weight loss determination:
    Emissions weight loss (g) = Initial resin weight (g)-Final resin 
weight (g)
    12.2.7 % Emission weight loss:

% Emission Weight Loss = (Emission weight loss (g) Initial resin weight 
          (g) x 100

    12.2.8 Average % Emission Weight Loss (assuming six test runs):
    [GRAPHIC] [TIFF OMITTED] TR21AP03.010
    
    12.2.9 VSE Factor calculation:

VSE Factor = 1 -(Average % VS Emission Weight Loss/Average NVS Emission 
          Weight Loss)

    VSE Factor is used as input into the appropriate equation in Table 1 
to this subpart.
    Example from Table 1 to this subpart:

Manual Resin Application, 35 percent HAP resin, VSE Factor of 0.45
HAP Emissions with vapor suppresants = ((0.286 x %HAP)-0.0529) x 2000 x 
          (1-(0.5 x VSE factor))
HAP Emissions with vapor suppresants = ((0.286 x .35)-0.0529) x 2000 x 
          (1-(0.5 x .45))
HAP Emissions with vapor suppresants = 73 pounds of HAP emissions per 
          ton of resin.

                         13. Method Performance

    13.1 Bias:
    The bias of this test method has not been determined.
    13.2 Precision Testing
    13.2.1 Subsequent to the initial development of this test protocol 
by the Composites Fabricators Association, a series of tests were 
conducted in three different laboratory facilities. The purpose of this 
round robin testing was to verify the precision of the test method in 
various laboratories. Each laboratory received a sample of an 
orthophthalic polyester resin from the same production batch, containing 
48 per cent styrene by weight. Each testing site was also provided with 
the same vapor suppressant additive. The suppressant manufacturer 
specified the percentage level of suppressant additive. The resin 
manufacturer specified the type and level of initiator required to 
produce a 20 minute gel time. The target glass content was 30 percent by 
weight.
    13.2.2 Each laboratory independently conducted the VSE test 
according to this method. A summary of the results is included in Table 
13.1.

    13.3 Comparison to EPA Reference Methods This test has no 
corresponding EPA reference method.

                        14. Pollution Prevention

    The sample size used in this method produces a negligible emission 
of HAP, and has an insignificant impact upon the atmosphere.

                          15. Waste Management

    The spent and waste materials generated during this test are 
disposed according to required facility procedures, and waste management 
recommendations on the corresponding material safety data sheets.

    \1\ Balance Enclosure--The purpose of the balance enclosure is to 
prevent localized airflow from adversely affecting the laboratory 
balance. The enclosure may be a simple three-sided box with a top and an 
open face. The configuration of the enclosure is secondary to the 
purpose of providing a stable and steady balance reading, free from the 
effects of airflow, for accurate measurements. The enclosure can be 
fabricated locally. A typical enclosure is shown in Figure 17.1.

    \15\ Certificate of Analysis: Resin gel time, as recorded on the 
resin certificate of analysis, is measured using a laboratory standard 
gel time procedure. This procedure typically uses a 100 gram cup sample 
at 77 [deg]F (25 [deg]C), a specific type of initiator and a specified 
percentage.
    \16\ Roll-out times may vary with resin viscosity or resin additive. 
The important aspect of this step is to produce the same roll-out time 
for both the suppressed and non-suppressed samples.
    \17\ While this test can be used with filled resin systems, the test 
is not designed to determine the effect of the filler on emissions, but 
rather to measure the effect of the suppressant additive in the resin 
system. When evaluating a filled system both the non-vapor suppressed 
and vapor suppressed samples should be formulated with the same type and 
level of filler.

Subpart XXXX--National Emissions Standards for Hazardous Air Pollutants: 
                        Rubber Tire Manufacturing

    Source: 67 FR 45598, July 9, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.5980  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for rubber tire manufacturing. This subpart also 
establishes requirements to demonstrate

[[Page 656]]

initial and continuous compliance with the emission limitations.



Sec. 63.5981  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a rubber 
tire manufacturing facility that is located at, or is a part of, a major 
source of hazardous air pollutant (HAP) emissions.
    (1) Rubber tire manufacturing includes the production of rubber 
tires and/or the production of components integral to rubber tires, the 
production of tire cord, and the application of puncture sealant. 
Components of rubber tires include, but are not limited to, rubber 
compounds, sidewalls, tread, tire beads, tire cord and liners. Other 
components often associated with rubber tires but not integral to the 
tire, such as wheels, inner tubes, tire bladders, and valve stems, are 
not components of rubber tires or tire cord and are not subject to this 
subpart.
    (2) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area and under common 
control that emits or has the potential to emit considering controls, in 
the aggregate, any single HAP at a rate of 9.07 megagrams (10 tons) or 
more per year or any combination of HAP at a rate of 22.68 megagrams (25 
tons) or more per year.
    (b) You are not subject to this subpart if the affected source at 
your rubber tire manufacturing facility meets either of the conditions 
described in paragraph (b)(1) or (2) of this section.
    (1) You own or operate a tire cord production affected source, but 
the primary product produced at the affected source is determined to be 
subject to another subpart under this part 63 as of the effective date 
of that subpart (publication date of the final rule) or startup of the 
source, whichever is later. In this case, you must determine which 
subpart applies to your source and you must be in compliance with the 
applicable subpart by the compliance date of that subpart. The primary 
product is the product that is produced for the greatest operating time 
over a 5-year period, based on expected utilization for the 5 years 
following the compliance date or following initial startup of the 
source, whichever is later.
    (2) Your rubber tire manufacturing affected source is a research and 
development facility whose primary purpose is to conduct research and 
development into new processes and products, where such source is 
operated under the close supervision of technically trained personnel 
and is not engaged in the manufacture of products for commercial sale in 
commerce, except in a de minimis manner.



Sec. 63.5982  What parts of my facility does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed 
affected source at facilities engaged in the manufacture of rubber tires 
or their components.
    (b) The affected sources are defined in paragraph (b)(1) of this 
section (tire production), paragraph (b)(2) of this section (tire cord 
production), paragraph (b)(3) of this section (puncture sealant 
application), and paragraph (b)(4) of this section (rubber processing).
    (1) The tire production affected source is the collection of all 
processes that use or process cements and solvents as defined in 
Sec. 63.6015, located at any rubber tire manufacturing facility. It 
includes, but is not limited to: Storage and mixing vessels and the 
transfer equipment containing cements and/or solvents; wastewater 
handling and treatment operations; tread and cement operations; tire 
painting operations; ink and finish operations; undertread cement 
operations; process equipment cleaning materials; bead cementing 
operations; tire building operations; green tire spray operations; 
extruding, to the extent cements and solvents are used; cement house 
operations; marking operations; calendar operations, to the extent 
solvents are used; tire striping operations; tire repair operations; 
slab dip operations; other tire building operations, to the extent that 
cements and solvents are used; and balance pad operations.
    (2) The tire cord production affected source is the collection of 
all processes engaged in the production of tire cord. It includes, but 
is not limited to: dipping operations, drying ovens, heat-set

[[Page 657]]

ovens, bulk storage tanks, mixing facilities, general facility vents, 
air pollution control devices, and warehouse storage vents.
    (3) The puncture sealant application affected source is the puncture 
sealant application booth operation used to apply puncture sealant to 
finished tires.
    (4) The rubber processing affected source is the collection of all 
rubber mixing processes (e.g., banburys and associated drop mills) that 
either mix compounds or warm rubber compound before the compound is 
processed into components of rubber tires. The mixed rubber compound 
itself is also included in the rubber processing affected source. There 
are no emission limitations or other requirements for the rubber 
processing affected source.
    (c) An affected source is a new affected source if construction of 
the affected source commenced after October 18, 2000, and it met the 
applicability criteria of Sec. 63.5981 at the time construction 
commenced.
    (d) An affected source is reconstructed if it meets the criteria as 
defined in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.5983  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, except as 
provided in Secs. 63.5982(b)(4) and 63.5981(b)(1), you must comply with 
the emission limitations for new and reconstructed sources in this 
subpart upon startup.
    (b) If you have an existing affected source, you must comply with 
the emission limitations for existing sources no later than July 11, 
2005.
    (c) If you have an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP, the 
affected source(s) must be in compliance with existing source emission 
limitations no later than 3 years after the date on which the area 
source became a major source.
    (d) You must meet the notification requirements in Sec. 63.6009 
according to the schedule in Sec. 63.6009 and in subpart A of this part. 
Some of the notifications must be submitted before the date you are 
required to comply with the emission limitations in this subpart.

    (d) If you commenced construction or reconstruction between October 
18, 2000 and July 9, 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 no later than January 5, 2006, or after startup of the 
source, whichever is later, according to Sec. 63.7(a)(2)(ix).



Sec. 63.5992  When must I conduct subsequent performance tests?

    If you use a control system (add-on control device and capture 
system) to meet the emission limitations, you must also conduct a 
performance test at least once every 5 years following your initial 
compliance demonstration to verify control system performance and 
reestablish operating parameters or operating limits for control systems 
used to comply with the emissions limits.



Sec. 63.5993  What performance tests and other procedures must I use?

    (a) If you use a control system to meet the emission limitations, 
you must conduct each performance test in Table 5 to this subpart that 
applies to you.
    (b) Each performance test must be conducted according to the 
requirements in Sec. 63.7(e)(1) and under the specific conditions 
specified in Table 5 to this subpart.
    (c) You may not conduct performance tests during periods of startup, 
shutdown, or malfunction, as specified in Sec. 63.7(e)(1).
    (d) You must conduct three separate test runs for each performance 
test required in this section, as specified in Sec. 63.7(e)(1), unless 
otherwise specified in the test method. Each test run must last at least 
1 hour.

alternative to constructing a permanent or temporary total enclosure, 
you may determine the capture efficiency using any capture efficiency 
protocol and test methods if the data satisfy the criteria of either the 
Data Quality Objective or the Lower Confidence Limit approach in 
appendix A to subpart KK of this part.
    (3) Determining efficiency of an add-on control device. Use Table 5

Testing and Initial Compliance Requirements for Tire Production Affected 
                                 Sources



Sec. 63.5994  How do I conduct tests and procedures for tire production affected sources?

    (a) Methods to determine the mass percent of HAP in cements and 
solvents. To determine the HAP content in the cements and solvents used 
at your tire production affected source, use EPA Method 311 of appendix 
A of this part, an approved alternative method, or any other reasonable 
means for determining the HAP content of your cements and solvents. 
Other reasonable means include, but are not limited to: a material 
safety data sheet (MSDS), provided it contains appropriate information; 
a certified product data sheet (CPDS); or a manufacturer's hazardous air 
pollutant data sheet. You are not required to test the materials that 
you use, but the Administrator may require a test using EPA Method 311 
(or an approved alternative method) to confirm the reported HAP content. 
If the results of an analysis by EPA Method 311 are different from the 
HAP content determined by another means, the EPA Method 311 results will 
govern compliance determinations.
    (b) Methods to demonstrate compliance with the HAP constituent 
emission limits in Table 1 to this subpart (option 1). Use the method in 
paragraph (b)(1) of this section to demonstrate initial and continuous 
compliance with the applicable emission limits for tire production 
affected sources using the compliance alternative described in 
Sec. 63.5985(a), purchase alternative. Use the equations in paragraphs 
(b)(2) and (3) of this section to demonstrate initial and continuous 
compliance with the emission limits for tire production affected sources 
using the monthly average compliance alternatives described in 
Sec. 63.5985(b) and (c).
    (1) Determine the mass percent of each HAP in each cement and 
solvent according to the procedures in paragraph (a) of this section.
    (2) Use Equation 1 of this section to calculate the HAP emission 
rate for each monthly operating period when complying by using cements 
and solvents without using an add-on control device so that the monthly 
average HAP emissions do not exceed the HAP constituent emission limits 
in Table 1 to this subpart, option 1. Equation 1 follows:

rate for each monthly period when complying by using a control device to 
reduce HAP emissions so that the monthly average HAP emissions do not 
exceed the HAP constituent emission limits in Table 1 to this subpart

days, which are defined as days when the control system is operating 
within the operating range established during the performance test and 
when monitoring data are collected.
TMASSj=total mass of cement and solvent j used in the month 
in processes that are routed to a control device during all operating 
days, grams.
EFF=efficiency of the control system determined during the performance 
test (capture system efficiency multiplied by the control device

(megagrams) by accounting for the total mass of mixed rubber compound 
that is delivered to the tire production operation.
    (3) Compliance without use of an add-on control device. If you do 
not use an add-on control device to meet the emission limits, use

    (2) If you are demonstrating compliance with the HAP constituent 
option in Table 1 to this subpart, option 1, conduct the compliance 
demonstration

[[Page 663]]

using cements and solvents that are representative of cements and

    (3) Establish an operating range that corresponds to the control 
efficiency as described in Table 5 to this subpart.
    (e) How to take credit for HAP emissions reductions from add-on

stream mass or volumetric flow for each regeneration cycle, and the 
carbon bed temperature after each regeneration, and within 15 minutes of 
completing any cooling cycle.
    (iii) If you use a control device other than a thermal oxidizer or a 
regenerative carbon adsorber, install and operate a continuous parameter 
monitoring system according to your site-specific performance test plan 
submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face

have not changed, that there are no new NDO, and that a HAP emission 
source has not been moved closer to an NDO since the last compliance 
demonstration was conducted.

identified in your monitoring plan.
    (2) Maintain the operating parameters within the operating range 
established during the compliance demonstration.

combined. When performing material balances to demonstrate compliance, 
if the storage of materials, exhaust, or the wastewater from more than 
one affected source are combined at the point where control systems are 
applied, any credit for emissions reductions needs to be prorated among 
the affected sources based on the ratio of their contribution to the 
uncontrolled emissions.

  Testing and Initial Compliance Requirements for Tire Cord Production 
                            Affected Sources



Sec. 63.5997  How do I conduct tests and procedures for tire cord production affected sources?

    (a) Methods to determine the mass percent of each HAP in coatings. 
(1) To determine the HAP content in the coating used at your tire cord 
production affected source, use EPA Method 311 of appendix A of this 
part, an approved alternative method, or any other reasonable means for 
determining the HAP content of your coatings. Other reasonable means 
include, but are not limited to: an MSDS, provided it contains 
appropriate information; a CPDS; or a manufacturer's HAP data sheet. You 
are not required to test the materials that you use, but the 
Administrator may require a test using EPA Method 311 (or an approved 
alternative method)

[[Page 665]]

to confirm the reported HAP content. If the results of an analysis by 
EPA Method 311 are different from the HAP content determined by another 
means, the EPA Method 311 results will govern compliance determinations.
    (2) Unless you demonstrate otherwise, the HAP content analysis must 
be based on coatings prior to any cross-linking reactions, i.e., curing. 
However, you may account for differences in HAP emissions resulting from 
chemical reactions based on the conversion rates of the individual 
coating formulations, chemistry demonstrations, or other demonstrations 
that are verifiable to the approving agency. Use the revised value in 
your compliance demonstration in the relevant equations in paragraph (b) 
of this section.
    (b) Methods to determine compliance with the emission limits in 
Table 2 to this subpart, option 1. Use the equations in this paragraph

    (1) Determine mass percent of HAP. Determine the mass percent of all 
HAP in each coating according to the procedures in paragraph (a) of this 
section.

grams of HAP emitted per megagram of fabric processed at the tire cord 
production source to show that the monthly average HAP emissions do not 
exceed the emission limits in Table 2 to this subpart, option 1.

control devices. If you want to take credit in Equations 2 and 4 of this 
section for HAP emissions reduced using a control system, you must meet 
the requirements in paragraphs (e)(1) and (2) of this section.
    (1) Monitor the established operating parameters as appropriate.
    (i) If you use a thermal oxidizer, continuously monitor the firebox 
secondary chamber temperature.
    (ii) If you use a carbon adsorber, monitor the total regeneration 
stream mass or volumetric flow for each regeneration cycle and the 
carbon bed temperature after each regeneration and within 15 minutes of 
completing any cooling cycle.
    (iii) If you use a control device other than a thermal oxidizer or a 
regenerative carbon adsorber, install and operate a continuous parameter 
monitoring system according to your site-specific performance test plan 
submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face 
velocity across the NDO in the enclosure. Also, if you use an enclosure, 
monitor to ensure that the sizes of the NDO have not changed, that there 
are no new NDO, and that a HAP emission source has not been moved closer 
to an NDO since the last performance test was conducted.
    (v) If you use other capture systems, monitor the parameters 
identified in your monitoring plan.

[[Page 668]]

    (2) Maintain the operating parameter within the operating range 
established during the compliance demonstration.
    (f) How to take credit for HAP emissions reductions when streams are 
combined. When performing material balances to demonstrate compliance, 
if the storage of materials, exhaust, or the wastewater from more than 
one affected source are combined at the point where control systems are 
applied, any credit for emissions reductions needs to be prorated among 
the affected sources based on the ratio of their contribution to the 
uncontrolled emissions.

    (a) You must demonstrate initial compliance with each emission limit 
that applies to you according to Table 7 to this subpart.
    (b) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.6009(e).

    Testing and Initial Compliance Requirements for Puncture Sealant 
                      Application Affected Sources



Sec. 63.6000  How do I conduct tests and procedures for puncture sealant application affected sources?

    (a) Methods to determine compliance with the puncture sealant 
application emission limitations in Table 3 to this subpart. Use the 
methods and equations in paragraph (b) of this section to demonstrate 
initial and continuous compliance with the overall control efficiency 
compliance alternatives described in Sec. 63.5989(a) and (b). Use the 
methods and equations in paragraphs (c) through (g) of this section to 
demonstrate initial and continuous compliance with the HAP constituent 
compliance alternative described in Sec. 63.5989(c) and (d).
    (b) Methods to determine compliance with the emission limits in 
Table 3 to this subpart, option 1. Follow the test procedures described 
in Sec. 63.5993 to determine the overall control efficiency of your 
system.
    (1) You must also meet the requirements in paragraphs (b)(1)(i) and 
(ii) of this section.
    (i) Conduct the performance test using a puncture sealant with an 
average mass percent HAP content that is representative of the puncture 
sealants typically used at your puncture sealant application affected 
source.
    (ii) Establish all applicable operating limit ranges that correspond 
to the control system efficiency as described in Table 5 to this 
subpart.
    (2) Use Equation 1 of this section to calculate the overall 
efficiency of the control system. If you have a permanent total 
enclosure that satisfies EPA Method 204 (found in 40 CFR part 51, 
appendix M) criteria, assume 100 percent capture efficiency for variable 
F. Equation 1 follows:
[GRAPHIC] [TIFF OMITTED] TR09JY02.008

Where:

R=overall control system efficiency, percent.
F=capture efficiency of the capture system on add-on control device, 
percent, determined during the performance test.
E=control efficiency of add-on control device k, percent, determined 
during the performance test.

    (3) Monitor the established operating limits as appropriate.

[[Page 669]]

    (i) If you use a thermal oxidizer, monitor the firebox secondary 
chamber temperature.
    (ii) If you use a carbon adsorber, monitor the total regeneration 
stream mass or volumetric flow for each regeneration cycle, and the 
carbon bed temperature after each regeneration, and within 15 minutes of 
completing any cooling cycle.
    (iii) For each control device used other than a thermal oxidizer or 
a regenerative carbon adsorber, install and operate a continuous 
parameter monitoring system according to your site-specific performance 
test plan submitted according to Sec. 63.7(c)(2)(i).
    (iv) If you use a permanent total enclosure, monitor the face 
velocity across the NDO in the enclosure. Also, if you use an enclosure, 
monitor to ensure that the sizes of the NDO have not changed, that there 
are no new NDO, and that a HAP emission source has not been moved closer 
to an NDO since the last performance test was conducted.
    (v) If you use other capture systems, monitor the parameters 
identified in your monitoring plan.
    (vi) Maintain the operating parameter within the operating range 
established during the performance test.
    (c) Methods to determine the mass percent of each HAP in puncture 
sealants. To determine the HAP content in the puncture sealant used at 
your puncture sealant application affected source, use EPA Method 311 of 
appendix A of 40 CFR part 63, an approved alternative method, or any 
other reasonable means for determining the HAP content of your puncture 
sealants. Other reasonable means include, but are not limited to: an 
MSDS, provided it contains appropriate information; a CPDS; or a 
manufacturer's hazardous air pollutant data sheet. You are not required 
to test the materials that you use, but the Administrator may require a 
test using EPA Method 311 (or an approved alternative method) to confirm 
the reported HAP content. If the results of an analysis by EPA Method 
311 are different from the HAP content determined by another means, the 
EPA Method 311 results will govern compliance determinations.
    (d) Methods to determine compliance with the emission limits in 
Table 3 to this subpart, option 2. Use the equations in this paragraph 
(d) to demonstrate initial and continuous compliance with the HAP 
constituent emission limits for puncture sealant application affected 
sources using the compliance alternatives described in Sec. 63.5989(c) 
and (d).
    (1) Use Equation 2 of this section to calculate the monthly average 
HAP emission rate when complying by using puncture sealants without 
using an add-on control device to show that the monthly average HAP 
emissions do not exceed the emission limits in Table 3 to this subpart, 
option 2. Equation 2 follows:
[GRAPHIC] [TIFF OMITTED] TR09JY02.009

Where:

Emonth=mass of the specific HAP emitted per total mass of 
puncture sealants from all puncture sealants used at the puncture 
sealant affected source per month, grams per megagram.
HAPi=mass percent, expressed as a decimal, of the specific 
HAP in puncture sealant i, including any application booth dilution, 
determined in accordance with paragraph (c) of this section.
TPSEALi=total mass of puncture sealant i used in the month, 
grams.
n=number of puncture sealants used in the month.

HAP, in puncture sealant j, including any application booth dilution, 
determined in accordance with paragraph (c) of this section, for 
puncture sealants used in the month in processes that are routed to a 
control device during operating days, which are defined as days when the 
control system is operating within the operating range established 
during the performance test and when monitoring data are collected.
TPSEALj=total mass of puncture sealant j used in the month in 
processes that are routed to a control device during all operating days, 
grams.
EFF=efficiency of the control system determined during the performance 
test (capture system efficiency multiplied by the control device 
efficiency), percent.
m=number of puncture sealants used in the month that are routed to a 
control device during all operating days.
HAPk=mass percent, expressed as a decimal, of the specific 
HAP, in puncture sealant k, including any application booth dilution, 
for puncture sealants used in the month in processes that are routed to 
a control device during non-control operating days, which are defined as 
days when either the control system is not operating within the 
operating range established during the performance test or when 
monitoring data are not collected.
TPSEALk=total mass of total mass of puncture sealant k used 
in the month in processes that are routed to a control device during all 
non-control operating days, grams.
p=number of puncture sealants used in the month that are routed to a

control devices. If you want to take credit in Equation 3 of this 
section for HAP emissions reduced using a control system, you must 
monitor the established operating parameters as appropriate and meet the 
requirements in paragraph (b)(3) of this section.
    (g) How to take credit for HAP emissions reductions when streams are 
combined. When performing material balances to demonstrate compliance, 
if the storage of materials, exhaust, or the wastewater from more than 
one affected source are combined at the point where control systems are 
applied, any credit for emissions reductions needs

limited to, solvent constituents, mixed rubber compound, and process oil 
that is applied to the inner liner of a finished tire for the purpose of 
sealing any future hole which might occur in the tread when an object 
penetrates the tire.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Rubber means the sum of the materials (for example, natural rubber, 
synthetic rubber, carbon black, oils, sulfur) that are combined in 
specific formulations for the sole purpose of making rubber tires or 
components of rubber tires.
    Rubber mixing means the physical process of combining materials for 
use in rubber tire manufacturing to make mixed rubber compound using the 
collection of banburys and associated drop mills.
    Rubber tire means a continuous solid or pneumatic cushion typically 
encircling a wheel and usually consisting, when pneumatic, of an 
external rubber covering.
    Rubber used means the total mass of mixed rubber compound delivered 
to the tire production operations in a tire manufacturing facility 
(e.g., the collection of warm-up mills, extruders, calendars, tire 
building, or other tire component and tire manufacturing equipment).

                     Subpart YYYY--AAAAA [Reserved]



  



Subpart BBBBB--National Emission Standards for Hazardous Air Pollutants 
                     for Semiconductor Manufacturing

    Source: 68 FR 27925, May 22, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.7180  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for semiconductor manufacturing facilities. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission standards.



Sec. 63.7181  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a 
semiconductor manufacturing process unit that is a major source of 
hazardous air pollutants (HAP) emissions or that is located at, or is 
part of, a major source of HAP emissions.
    (b) A major source of HAP emissions is any stationary source or 
group of stationary sources located within a contiguous area and under 
common control that emits or has the potential to emit, considering 
controls, in the aggregate, any single HAP at a rate of 10 tons per year 
(tpy) or more or any combination of HAP at a rate of 25 tpy or more.



Sec. 63.7182  What parts of my facility does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source that you own or operate that manufactures 
semiconductors.
    (b) An affected source subject to this subpart is the collection of 
all semiconductor manufacturing process units used to manufacture p-type 
and n-type semiconductors and active solid-state devices from a wafer 
substrate, including research and development activities integrated into 
a semiconductor manufacturing process unit. A semiconductor 
manufacturing process unit includes the equipment assembled and 
connected by ductwork or hard-piping including furnaces and associated 
unit operations; associated wet and dry

[[Page 693]]

work benches; associated recovery devices; feed, intermediate, and 
product storage tanks; product transfer racks and connected ducts and 
piping; pumps, compressors, agitators, pressure-relief devices, sampling 
connecting systems, open-ended valves or lines, valves, connectors, and 
instrumentation systems; and control devices.
    (c) Your affected source is a new affected source if you commence 
construction of the affected source after May 8, 2002, and you meet the 
applicability criteria in Sec. 63.7181 at the time you commence 
construction.
    (d) Your affected source is a reconstructed affected source if you 
meet the criteria for ``reconstruction,'' as defined in Sec. 63.2.
    (e) Your source is an existing affected source if it is not a new or 
reconstructed affected source.



Sec. 63.7183  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section.
    (1) If you start up your affected source before May 22, 2003, then 
you must comply with the emission standards for new and reconstructed 
sources in this subpart no later than May 22, 2003.
    (2) If you start up your affected source after May 22, 2003, then 
you must comply with the emission standards for new and reconstructed 
sources in this subpart upon startup of your affected source.
    (b) If you have an existing affected source, you must comply with 
the emission standards for existing sources no later than 3 years from 
May 22, 2003.
    (c) If you have an area source that increases its emissions or its 
potential to emit such that it becomes a major source of HAP and an 
affected source subject to this subpart, paragraphs (c)(1) and (2) of 
this section apply.
    (1) Any portion of your existing facility that is a new affected 
source as specified at Sec. 63.7182(c), or a reconstructed affected 
source as specified at Sec. 63.7182(d), must be in compliance with this 
subpart upon startup.
    (2) Any portion of your facility that is an existing affected 
source, as specified at Sec. 63.7182(e), must be in compliance with this 
subpart by not later than 3 years after it becomes a major source.
    (d) You must meet the notification requirements in Sec. 63.7189 and 
in subpart A of this part. You must submit some of the notifications 
(e.g., Initial Notification) before the date you are required to comply 
with the emission limitations in this subpart.

                           Emission Standards



Sec. 63.7184  What emission limitations, operating limits, and work practice standards must I meet?

    (a) If you have a new, reconstructed, or existing affected source, 
as defined in Sec. 63.7182(b), you must comply with all applicable 
emission limitations in this section on and after the compliance dates 
specified in Sec. 63.7183.
    (b) Process vents--organic HAP emissions. For each process vent that 
emits organic HAP, other than process vents from storage tanks, you must 
limit organic HAP emissions to the level specified in paragraph (b)(1) 
or (2) of this section. These limitations can be met by venting 
emissions from your process vent through a closed vent system to any 
combination of control devices meeting the requirements of 
Sec. 63.982(a)(2).
    (1) Reduce the emissions of organic HAP from the process vent stream 
by 98 percent by weight.
    (2) Reduce or maintain the concentration of emitted organic HAP from 
the process vent to less than or equal to 20 parts per million by volume 
(ppmv).
    (c) Process vents--inorganic HAP emissions. For each process vent 
that emits inorganic HAP, other than process vents from storage tanks, 
you must limit inorganic HAP emissions to the level specified in 
paragraph (c)(1) or (2) of this section. These limitations can be met by 
venting emissions from your process vent through a closed vent system to 
a halogen scrubber meeting the requirements of Secs. 63.983 (closed vent 
system requirements) and 63.994 (halogen scrubber requirements); the 
applicable general monitoring requirements of Sec. 63.996; the 
applicable performance test requirements; and the monitoring,

[[Page 694]]

recordkeeping and reporting requirements referenced therein.
    (1) Reduce the emissions of inorganic HAP from the process vent 
stream by 95 percent by weight.
    (2) Reduce or maintain the concentration of emitted inorganic HAP 
from the process vent to less than or equal to 0.42 ppmv.
    (d) Storage tanks. For each storage tank, 1,500 gallons or larger, 
you must limit total HAP emissions to the level specified in paragraph 
(d)(1) or (2) of this section if the emissions from the storage tank 
vent contains greater than 0.42 ppmv inorganic HAP. These limitations 
can be met by venting emissions from your storage tank through a closed 
vent system to a halogen scrubber meeting the requirements of 
Secs. 63.983 (closed vent system requirements) and 63.994 (halogen 
scrubber requirements); the applicable general monitoring requirements 
of Sec. 63.996; the applicable performance test requirements; and the 
monitoring, recordkeeping and reporting requirements referenced therein.
    (1) Reduce the emissions of inorganic HAP from each storage tank by 
95 percent by weight.
    (2) Reduce or maintain the concentration of emitted inorganic HAP 
from the process vent to less than or equal to 0.42 ppmv.
    (e) You must comply with the applicable work practice standards and 
operating limits contained in Sec. 63.982(a)(1) and (2). The closed vent 
system inspection requirements of Sec. 63.983(c), as referenced by 
Sec. 63.982(a)(1) and (2), do not apply.

                         Compliance Requirements



Sec. 63.7185  What are my general requirements for complying with this subpart?

    (a) You must be in compliance with the requirements of Sec. 63.7184 
at all times, except during periods of startup, shutdown, or 
malfunction.
    (b) 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).
    (c) You must develop and implement a written startup, shutdown, and 
malfunction plan (SSMP). Your SSMP must be prepared in accordance with 
the provisions in Sec. 63.6(e)(3).
    (d) You must perform all the items listed in paragraphs (d)(1) 
through (3) of this section:
    (1) Submit the necessary notifications in accordance with 
Sec. 63.7189.
    (2) Submit the necessary reports in accordance with Sec. 63.7190.
    (3) Maintain all necessary records you have used to demonstrate 
compliance with this subpart in accordance with Sec. 63.7191.



Sec. 63.7186  By what date must I conduct performance tests or other initial compliance demonstrations?

    For each process vent or storage tank vent emission limitation in 
Sec. 63.7184 for which initial compliance is demonstrated by meeting a 
percent by weight HAP emissions reduction, or a HAP concentration 
limitation, you must conduct performance tests or an initial compliance 
demonstration within 180 days after the compliance date that is 
specified for your source in Sec. 63.7183 and according to the 
provisions in Sec. 63.7(a)(2).



Sec. 63.7187  What performance tests and other compliance procedures must I use?

    (a) You must conduct each performance test in Table 1 to this 
subpart that applies to you as specified for process vents in 
Sec. 63.982(a)(2) and storage tanks in Sec. 63.982(a)(1). Performance 
tests must be conducted under maximum operating conditions or HAP 
emissions potential. Section 63.982(a)(1) and (2) only includes methods 
to measure the total organic regulated material or total organic carbon 
(TOC) concentration. The EPA Methods 26 and 26A are included in Table 1 
to this subpart in addition to the test methods contained within 
Sec. 63.982(a)(1) and (2). The EPA Method 26 or 26A must be used for 
testing regulated material containing inorganic HAP. Method 320 of 40 
CFR part 63, appendix A, must be used to measure total vapor phase 
organic and inorganic HAP concentrations.
    (b) If, without the use of a control device, your process vent 
stream has an organic HAP concentration of 20 ppmv

[[Page 695]]

or less or an inorganic HAP concentration of 0.42 ppmv or less, or your 
storage tank vent stream has an inorganic HAP concentration of 0.42 ppmv 
or less, you may demonstrate that the vent stream is compliant by 
engineering assessments and calculations or by conducting the applicable 
performance test requirements specified in Table 1 to this subpart. Your 
engineering assessments and calculations, as with performance tests (as 
specified in Sec. 63.982(a)(1) and (2)), must represent your maximum 
operating conditions or HAP emissions potential and must be approved by 
the Administrator. You must demonstrate continuous compliance by 
certifying that your operations will not exceed the maximum operating 
conditions or HAP emissions potential represented by your engineering 
assessments, calculations, or performance test.
    (c) If you are using a control device to comply with the emission 
limitations in Sec. 63.7184 and the inlet concentration of HAP to the 
control device is 20 ppmv or less, then you may demonstrate that the 
control device meets the percent by weight HAP emission reduction 
limitation in Sec. 63.7184(c)(1) or (d)(1) by conducting a design 
evaluation as specified in paragraph (i) of this section. Your design 
evaluation must represent your maximum operating conditions or HAP 
emissions potential and must be approved by the Administrator. You must 
demonstrate continuous compliance by certifying that your operations 
will not exceed the maximum operating conditions or HAP emissions 
potential represented by your design evaluation.
    (d) During periods of startup, shutdown, and malfunction, you must 
operate in accordance with your SSMP.
    (e) For each monitoring system required in this section, you must 
develop and submit for approval a site-specific monitoring plan that 
addresses the criteria specified in paragraphs (e)(1) through (3) of 
this section.
    (1) Installation of the continuous monitoring system (CMS) sampling 
probe or other interface at a measurement location relative to each 
affected process unit such that the measurement is representative of 
control of the exhaust emissions (e.g., on or downstream of the last 
control device);
    (2) Performance and equipment specifications for the sample 
interface, the pollutant concentration or parametric signal analyzer, 
and the data collection and reduction system; and
    (3) Performance evaluation procedures and acceptance criteria (e.g., 
calibrations).
    (f) In your site-specific monitoring plan, you must also address the 
procedural processes in paragraphs (f)(1) through (3) of this section.
    (1) Ongoing operation and maintenance procedures in accordance with 
the general requirements of Sec. 63.8(c)(1), (3), (4)(ii), (7), and (8);
    (2) Ongoing data quality assurance procedures in accordance with the 
general requirements of Sec. 63.8(d); and
    (3) Ongoing recordkeeping and reporting procedures in accordance 
with the general requirements of Sec. 63.10(c), (e)(1), and (e)(2)(i).
    (g) You must conduct a performance evaluation of each CMS in 
accordance with your site-specific monitoring plan.
    (h) You must operate and maintain the CMS in continuous operation 
according to the site-specific monitoring plan.
    (i) Design evaluation. To demonstrate that a control device meets 
the required percent by weight inorganic HAP emission reduction 
limitation in Sec. 63.7184(c)(1) or (d)(1), a design evaluation must 
address the composition of the inorganic HAP concentration of the vent 
stream entering the control device. A design evaluation also must 
address other vent stream characteristics and control device operating 
parameters as specified in any one of paragraphs (i)(1) through (5) of 
this section, depending on the type of control device that is used. If 
the vent stream is not the only inlet to the control device, the 
efficiency demonstration must also consider all other vapors, gases, and 
liquids, other than fuels, received by the control device.
    (1) For a condenser, the design evaluation shall consider the vent 
stream flow rate, relative humidity, and temperature and shall establish 
the design

[[Page 696]]

outlet organic HAP compound concentration level, design average 
temperature of the condenser exhaust vent stream, and the design average 
temperatures of the coolant fluid at the condenser inlet and outlet. The 
temperature of the gas stream exiting the condenser must be measured and 
used to establish the outlet organic HAP concentration.
    (2) For a carbon adsorption system that regenerates the carbon bed 
directly onsite in the control device such as a fixed-bed adsorber, the 
design evaluation shall consider the vent stream flow rate, relative 
humidity, and temperature and shall establish the design exhaust vent 
stream organic compound concentration level, adsorption cycle time, 
number and capacity of carbon beds, type and working capacity of 
activated carbon used for carbon beds, design total regeneration stream 
mass or volumetric flow over the period of each complete carbon bed 
regeneration cycle, design carbon bed temperature after regeneration, 
design carbon bed regeneration time, and design service life of carbon. 
For vacuum desorption, the pressure drop shall be included.
    (3) For a carbon adsorption system that does not regenerate the 
carbon bed directly onsite in the control device such as a carbon 
canister, the design evaluation shall consider the vent stream mass or 
volumetric flow rate, relative humidity, and temperature and shall 
establish the design exhaust vent stream organic compound concentration 
level, capacity of carbon bed, type and working capacity of activated 
carbon used for carbon bed, and design carbon replacement interval based 
on the total carbon working capacity of the control device and source 
operating schedule.

Sec. 63.7195  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, in 
Secs. 63.2 and 63.981, the General Provisions of this part (40 CFR part 
63, subpart A), and in this section as follows:
    Control device means a combustion device, recovery device, recapture 
device, or any combination of these devices used for the primary purpose 
of reducing emissions to comply with this subpart. Devices that are 
inherent to a process or are integral to the operation of a process are 
not considered control devices for the purposes of this subpart, even 
though these devices may have the secondary effect of reducing 
emissions.
    Process vent means the point at which HAP emissions are released to 
the atmosphere from a semiconductor manufacturing process unit or 
storage tank by means of a stack, chimney, vent, or other functionally 
equivalent opening. The HAP emission points originating from wastewater 
treatment equipment, other than storage tanks, are not considered to be 
a process vent, unless the wastewater treatment equipment emission 
points are connected to a common vent or exhaust plenum with other 
process vents.
    Semiconductor manufacturing means the collection of semiconductor 
manufacturing process units used to manufacture p-type and n-type 
semiconductors or active solid state devices from a wafer substrate, 
including processing from crystal growth through wafer fabrication, and 
testing and assembly. Examples of semiconductor or related solid state 
devices include semiconductor diodes, semiconductor stacks, rectifiers, 
integrated circuits, and transistors.
    Semiconductor manufacturing process unit means the collection of 
equipment used to carry out a discrete operation

[[Page 700]]

in the semiconductor manufacturing process. These operations include, 
but are not limited to, crystal growing; solvent stations used to 
prepare and clean materials for subsequent processing or for parts 
cleaning; wet chemical stations used for cleaning (other than solvent 
cleaning); photoresist application, developing, and stripping; etching; 
gaseous operation stations used for stripping, cleaning, doping, 
etching, and layering; separation; encapsulation; and testing. Research 
and development operations associated with semiconductor manufacturing 
and conducted at a semiconductor manufacturing facility are considered 
to be semiconductor manufacturing process units.
    Storage tank means a stationary unit that is constructed primarily 
from nonearthen materials (such as wood, concrete, steel, fiberglass, or 
plastic) which provides structural support and is designed to hold an 
accumulation of liquids or other materials used in or generated by a 
semiconductor manufacturing process unit. The following are not storage 
tanks for the purposes of this subpart:
    (1) Tanks permanently attached to motor vehicles such as trucks, 
railcars, barges, or ships;
    (2) Flow-through tanks where wastewater undergoes treatment (such as 
pH adjustment) before discharge, and are not used to accumulate 
wastewater;
    (3) Bottoms receiver tanks; and
    (4) Surge control tanks.

Subpart CCCCC--National Emission Standards for Hazardous Air Pollutants 
         for Coke Ovens: Pushing, Quenching, and Battery Stacks

    Source: 68 FR 18025, Apr. 14, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.7280  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for pushing, soaking, quenching, and battery 
stacks at coke oven batteries. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with all 
applicable emission limitations, work practice standards, and

[[Page 702]]

operation and maintenance requirements in this subpart.



Sec. 63.7281  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a coke oven 
battery at a coke plant that is (or is part of) a major source of 
hazardous air pollutant (HAP) emissions. A major source of HAP is a 
plant site that emits or has the potential to emit any single HAP at a 
rate of 10 tons or more per year or any combination of HAP at a rate of 
25 tons or more per year.



Sec. 63.7282  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new or existing affected source at 
your coke plant. The affected source is each coke oven battery.
    (b) This subpart covers emissions from pushing, soaking, quenching, 
and battery stacks from each affected source.
    (c) An affected source at your coke plant is existing if you 
commenced construction or reconstruction of the affected source before 
July 3, 2001.
    (d) An affected source at your coke plant is new if you commenced 
construction or reconstruction of the affected source on or after July 
3, 2001. An affected source is reconstructed if it meets the definition 
of ``reconstruction'' in Sec. 63.2.



Sec. 63.7283  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

            Emission Limitations and Work Practice Standards



Sec. 63.7290  What emission limitations must I meet for capture systems and control devices applied to pushing emissions?

    (a) You must not discharge to the atmosphere emissions of 
particulate matter from a control device applied to pushing emissions 
from a new or existing coke oven battery that exceed the applicable 
limit in paragraphs (a)(1) through (4) of this section:
    (1) 0.01 grain per dry standard cubic foot (gr/dscf) if a cokeside 
shed is used to capture emissions;
    (2) 0.02 pound per ton (lb/ton) of coke if a moveable hood vented to 
a stationary control device is used to capture emissions;
    (3) If a mobile scrubber car that does not capture emissions during 
travel is used:
    (i) 0.03 lb/ton of coke for a control device applied to pushing 
emissions from a short battery, or
    (ii) 0.01 lb/ton of coke for a control device applied to pushing 
emissions from a tall battery; and
    (4) 0.04 lb/ton of coke if a mobile scrubber car that captures 
emissions during travel is used.
    (b) You must meet each operating limit in paragraphs (b)(1) through 
(3) of this section that applies to you for a new or existing coke oven 
battery.
    (1) For each venturi scrubber applied to pushing emissions, you must 
maintain the daily average pressure drop and scrubber water flow rate at 
or above the minimum levels established during the initial performance 
test.
    (2) For each hot water scrubber applied to pushing emissions, you 
must maintain the daily average water pressure and water temperature at 
or above

[[Page 703]]

the minimum levels established during the initial performance test.
    (3) For each capture system applied to pushing emissions, you must:
    (i) Maintain the daily average fan motor amperes at or above the 
minimum level established during the initial performance test; or
    (ii) Maintain the daily average volumetric flow rate at the inlet of 
the control device at or above the minimum level established during the 
initial performance test.



Sec. 63.7291  What work practice standards must I meet for fugitive pushing emissions if I have a by-product coke oven battery with vertical flues?

    (a) You must meet each requirement in paragraphs (a)(1) through (7) 
of this section for each new or existing by-product coke oven battery 
with vertical flues.
    (1) Observe and record the opacity of fugitive pushing emissions 
from each oven at least once every 90 days. If an oven cannot be 
observed during a 90-day period due to circumstances that were not 
reasonably avoidable, you must observe the opacity of the first push of 
that oven following the close of the 90-day period that is capable of 
being observed in accordance with the procedures in Sec. 63.7334(a), and 
you must document why the oven was not observed within a 90-day period. 
All opacity observations of fugitive pushing emissions for batteries 
with vertical flues must be made using the procedures in 
Sec. 63.7334(a).
    (2) If two or more batteries are served by the same pushing 
equipment and total no more than 90 ovens, the batteries as a unit can 
be considered a single battery.
    (3) Observe and record the opacity of fugitive pushing emissions for 
at least four consecutive pushes per battery each day. Exclude any push 
during which the observer's view is obstructed or obscured by 
interferences and observe the next available push to complete the set of 
four pushes. If necessary due to circumstances that were not reasonably 
avoidable, you may observe fewer than four consecutive pushes in a day; 
however, you must observe and record as many consecutive pushes as 
possible and document why four consecutive pushes could not be observed. 
You may observe and record one or more non-consecutive pushes in 
addition to any consecutive pushes observed in a day.
    (4) Do not alter the pushing schedule to change the sequence of 
consecutive pushes to be observed on any day. Keep records indicating 
the legitimate operational reason for any change in your pushing 
schedule which results in a change in the sequence of consecutive pushes 
observed on any day.
    (5) If the average opacity for any individual push exceeds 30 
percent opacity for any short battery or 35 percent opacity for any tall 
battery, you must take corrective action and/or increase coking time for 
that oven. You must complete corrective action or increase coking time 
within either 10 calendar days or the number of days determined using 
Equation 1 of this section, whichever is greater:


X = 0.55 * Y (Eq. 1)

Where:
X = Number of calendar days allowed to complete corrective action or 
    increase coking time; and
Y = Current coking time for the oven, hours.


For the purpose of determining the number of calendar days allowed under 
Equation 1 of this section, day one is the first day following the day 
you observed an opacity in excess of 30 percent for any short battery or 
35 percent for any tall battery. Any fraction produced by Equation 1 of 
this section must be counted as a whole day. Days during which the oven 
is removed from service are not included in the number of days allowed 
to complete corrective action.
    (6)(i) You must demonstrate that the corrective action and/or 
increased coking time was successful. After a period of time no longer 
than the number of days allowed in paragraph (a)(5) of this section, 
observe and record the opacity of the first two pushes for the oven 
capable of being observed using the procedures in Sec. 63.7334(a). The 
corrective action and/or increased coking time was successful if the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent

[[Page 704]]

or less for a tall battery. If the corrective action and/or increased 
coking time was successful, you may return the oven to the 90-day 
reading rotation described in paragraph (a)(1) of this section. If the 
average opacity of either push exceeds 30 percent for a short battery or 
35 percent for a tall battery, the corrective action and/or increased 
coking time was unsuccessful, and you must complete additional 
corrective action and/or increase coking time for that oven within the 
number of days allowed in paragraph (a)(5) of this section.
    (ii) After implementing any additional corrective action and/or 
increased coking time required under paragraph (a)(6)(i) or (a)(7)(ii) 
of this section, you must demonstrate that corrective action and/or 
increased coking time was successful. After a period of time no longer 
than the number of days allowed in paragraph (a)(5) of this section, you 
must observe and record the opacity of the first two pushes for the oven 
capable of being observed using the procedures in Sec. 63.7334(a). The 
corrective action and/or increased coking time was successful if the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery. If the 
corrective action and/or increased coking time was successful, you may 
return the oven to the 90-day reading rotation described in paragraph 
(a)(1) of this section. If the average opacity of either push exceeds 30 
percent for a short battery or 35 percent for a tall battery, the 
corrective action and/or increased coking time was unsuccessful, and you 
must follow the procedures in paragraph (a)(6)(iii) of this section.
    (iii) If the corrective action and/or increased coking time was 
unsuccessful as described in paragraph (a)(6)(ii) of this section, you 
must repeat the procedures in paragraph (a)(6)(ii) of this section until 
the corrective action and/or increased coking time is successful. You 
must report to the permitting authority as a deviation each unsuccessful 
attempt at corrective action and/or increased coking time under 
paragraph (a)(6)(ii) of this section.
    (7)(i) If at any time you place an oven on increased coking time as 
a result of fugitive pushing emissions that exceed 30 percent for a 
short battery or 35 percent for a tall battery, you must keep the oven 
on the increased coking time until the oven qualifies for decreased 
coking time using the procedures in paragraph (a)(7)(ii) or (a)(7)(iii) 
of this section.
    (ii) To qualify for a decreased coking time for an oven placed on 
increased coking time in accordance with paragraph (a)(5) or (6) of this 
section, you must operate the oven on the decreased coking time. After 
no more than two coking cycles on the decreased coking time, you must 
observe and record the opacity of the first two pushes that are capable 
of being observed using the procedures in Sec. 63.7334(a). If the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery, you may keep the 
oven on the decreased coking time and return the oven to the 90-day 
reading rotation described in paragraph (a)(1) of this section. If the 
average opacity of either push exceeds 30 percent for a short battery or 
35 percent for a tall battery, the attempt to qualify for a decreased 
coking time was unsuccessful. You must then return the oven to the 
previously established increased coking time, or implement other 
corrective action(s) and/or increased coking time. If you implement 
other corrective action and/or a coking time that is shorter than the 
previously established increased coking time, you must follow the 
procedures in paragraph (a)(6)(ii) of this section to confirm that the 
corrective action(s) and/or increased coking time was successful.
    (iii) If the attempt to qualify for decreased coking time was 
unsuccessful as described in paragraph (a)(7)(ii) of this section, you 
may again attempt to qualify for decreased coking time for the oven. To 
do this, you must operate the oven on the decreased coking time. After 
no more than two coking cycles on the decreased coking time, you must 
observe and record the opacity of the first two pushes that are capable 
of being observed using the procedures in Sec. 63.7334(a). If the 
average opacity for each of the two pushes is 30 percent or less for a 
short battery or 35 percent or less for a tall battery, you may keep the 
oven on the decreased coking time

[[Page 705]]

and return the oven to the 90-day reading rotation described in 
paragraph (a)(1) of this section. If the average opacity of either push 
exceeds 30 percent for a short battery or 35 percent for a tall battery, 
the attempt to qualify for a decreased coking time was unsuccessful. You 
must then return the oven to the previously established increased coking 
time, or implement other corrective action(s) and/or increased coking 
time. If you implement other corrective action and/or a coking time that 
is shorter than the previously established increased coking time, you 
must follow the procedures in paragraph (a)(6)(ii) of this section to 
confirm that the corrective action(s) and/or increased coking time was 
successful.
    (iv) You must report to the permitting authority as a deviation the 
second and any subsequent consecutive unsuccessful attempts on the same 
oven to qualify for decreased coking time as described in paragraph 
(a)(7)(iii) of this section.
    (b) As provided in Sec. 63.6(g), you may request to use an 
alternative to the work practice standards in paragraph (a) of this 
section.



Sec. 63.7292  What work practice standards must I meet for fugitive pushing emissions if I have a by-product coke oven battery with horizontal flues?

    (a) You must comply with each of the requirements in paragraphs 
(a)(1) through (4) of this section.
    (1) Prepare and operate by a written plan that will eliminate or 
minimize incomplete coking for each by-product coke oven battery with 
horizontal flues. You must submit the plan and supporting documentation 
to the Administrator (or delegated authority) for approval no later than 
90 days after completing all observations and measurements required for 
the study in paragraph (a)(3) of this section or April 14, 2004, 
whichever is earlier. You must begin operating by the plan requirements 
by the compliance date that is specified in Sec. 63.7283. The written 
plan must identify minimum flue temperatures for different coking times 
and a battery-wide minimum acceptable flue temperature for any oven at 
any coking time.
    (2) Submit the written plan and supporting documentation to the 
Administrator (or delegated authority) for review and approval. Include 
all data collected during the study described in paragraph (a)(3) of 
this section. If the Administrator (or delegated authority) disapproves 
the plan, you must revise the plan as directed by the Administrator (or 
delegated authority) and submit the amended plan for approval. The 
Administrator (or delegated authority) may require you to collect and 
submit additional data. You must operate according to your submitted 
plan (or submitted amended plan, if any) until the Administrator (or 
delegated authority) approves your plan.
    (3) You must base your written plan on a study that you conduct that 
meets each of the requirements listed in paragraphs (a)(3)(i) through 
(x) of this section.
    (i) Initiate the study by July 14, 2003. Notify the Administrator 
(or delegated authority) at least 7 days prior to initiating the study 
according to the requirements in Sec. 63.7340(f).
    (ii) Conduct the study under representative operating conditions, 
including but not limited to the range of moisture content and volatile 
matter in the coal that is charged.
    (iii) Include every oven in the study and observe at least two 
pushes from each oven.
    (iv) For each push observed, measure and record the temperature of 
every flue within 2 hours before the scheduled pushing time. Document 
the oven number, date, and time the oven was charged and pushed, and 
calculate the net coking time.
    (v) For each push observed, document the factors to be used to 
identify pushes that are incompletely coked. These factors must include 
(but are not limited to): average opacity during the push, average 
opacity during travel to the quench tower, average of six highest 
consecutive observations during both push and travel, highest single 
opacity reading, color of the emissions (especially noting any yellow or 
brown emissions), presence of excessive smoke during travel to the 
quench tower, percent volatile matter in the coke, percent volatile 
matter and percent moisture in the coal that is

[[Page 706]]

charged, and the date the oven was last rebuilt or completely relined. 
Additional documentation may be provided in the form of pictures or 
videotape of emissions during the push and travel. All opacity 
observations must be conducted in accordance with the procedures in 
Sec. 63.7334(a)(3) through (7).
    (vi) Inspect the inside walls of the oven after each observed push 
for cool spots as indicated by a flue that is darker than others (the 
oven walls should be red hot) and record the results.
    (vii) For each push observed, note where incomplete coking occurs if 
possible (e.g., coke side end, pusher side end, top, or center of the 
coke mass). For any push with incomplete coking, investigate and 
document the probable cause.
    (viii) Use the documented factors in paragraph (a)(3)(v) of this 
section to identify pushes that were completely coked and those that 
were not completely coked. Provide a rationale for the determination 
based on the documentation of factors observed during the study.
    (ix) Use only the flue temperature and coking time data for pushes 
that were completely coked to identify minimum flue temperatures for 
various coking times. Submit the criteria used to determine complete 
coking, as well as a table of coking times and corresponding 
temperatures for complete coking as part of your plan.
    (x) Determine the battery-wide minimum acceptable flue temperature 
for any oven. This temperature will be equal to the lowest temperature 
that provided complete coking as determined in paragraph (a)(3)(ix) of 
this section.
    (4) You must operate according to the coking times and temperatures 
in your approved plan and the requirements in paragraphs (a)(4)(i) 
through (viii) of this section.
    (i) Measure and record the percent volatile matter in the coal that 
is charged.
    (ii) Measure and record the temperature of all flues on two ovens 
per day within 2 hours before the scheduled pushing time for each oven. 
Measure and record the temperature of all flues on each oven at least 
once each month.
    (iii) For each oven observed in accordance with paragraph (a)(4)(ii) 
of this section, record the time each oven is charged and pushed and 
calculate and record the net coking time. If any measured flue 
temperature for an oven is below the minimum flue temperature for an 
oven's scheduled coking time as established in the written plan, 
increase the coking time for the oven to the coking time in the written 
plan for the observed flue temperature before pushing the oven.
    (iv) If you increased the coking time for any oven in accordance 
with paragraph (a)(4)(iii) of this section, you must investigate the 
cause of the low flue temperature and take corrective action to fix the 
problem. You must continue to measure and record the temperature of all 
flues for the oven within 2 hours before each scheduled pushing time 
until the measurements meet the minimum temperature requirements for the 
increased coking time for two consecutive pushes. If any measured flue 
temperature for an oven on increased coking time falls below the minimum 
flue temperature for the increased coking time, as established in the 
written plan, you must increase the coking time for the oven to the 
coking time specified in the written plan for the observed flue 
temperature before pushing the oven. The oven must continue to operate 
at this coking time (or at a longer coking time if the temperature falls 
below the minimum allowed for the increased coking time) until the 
problem has been corrected, and you have confirmed that the corrective 
action was successful as required by paragraph (a)(4)(v) of this 
section.
    (v) Once the heating problem has been corrected, the oven may be 
returned to the battery's normal coking schedule. You must then measure 
and record the flue temperatures for the oven within 2 hours before the 
scheduled pushing time for the next two consecutive pushes. If any flue 
temperature measurement is below the minimum flue temperature for that 
coking time established in the written plan, repeat the procedures in 
paragraphs (a)(4)(iii) and (iv) of this section.

[[Page 707]]

    (vi) If any flue temperature measurement is below the battery-wide 
minimum acceptable temperature for complete coking established in the 
written plan for any oven at any coking time, you must remove the oven 
from service for repairs.
    (vii) For an oven that has been repaired and returned to service 
after being removed from service in accordance with paragraph (a)(4)(vi) 
of this section, you must measure and record the temperatures of all 
flues for the oven within 2 hours before the first scheduled pushing 
time. If any flue temperature measurement is below the minimum flue 
temperature for the scheduled coking time, as established in the written 
plan, you must repeat the procedures described in paragraphs (a)(4)(iii) 
and (iv) of this section.
    (viii) For an oven that has been repaired and returned to service 
after removal from service in accordance with paragraph (a)(4)(vi) of 
this section, you must report as a deviation to the permitting authority 
any flue temperature measurement made during the initial coking cycle 
after return to service that is below the lowest acceptable minimum flue 
temperature.
    (b) As provided in Sec. 63.6(g), you may request to use an 
alternative to the work practice standards in paragraph (a) of this 
section.



Sec. 63.7293  What work practice standards must I meet for fugitive pushing emissions if I have a non-recovery coke oven battery?

    (a) You must meet the requirements in paragraphs (a)(1) and (2) of 
this section for each new and existing non-recovery coke oven battery.
    (1) You must visually inspect each oven prior to pushing by opening 
the door damper and observing the bed of coke.
    (2) Do not push the oven unless the visual inspection indicates that 
there is no smoke in the open space above the coke bed and that there is 
an unobstructed view of the door on the opposite side of the oven.
    (b) As provided in Sec. 63.6(g), you may request to use an 
alternative to the work practice standard in paragraph (a) of this 
section.



Sec. 63.7294  What work practice standard must I meet for soaking?

    (a) For each new and existing by-product coke oven battery, you must 
prepare and operate at all times according to a written work practice 
plan for soaking. Each plan must include measures and procedures to:
    (1) Train topside workers to identify soaking emissions that require 
corrective actions.
    (2) Damper the oven off the collecting main prior to opening the 
standpipe cap.
    (3) Determine the cause of soaking emissions that do not ignite 
automatically, including emissions that result from raw coke oven gas 
leaking from the collecting main through the damper, and emissions that 
result from incomplete coking.
    (4) If soaking emissions are caused by leaks from the collecting 
main, take corrective actions to eliminate the soaking emissions. 
Corrective actions may include, but are not limited to, reseating the 
damper, cleaning the flushing liquor piping, using aspiration, putting 
the oven back on the collecting main, or igniting the emissions.
    (5) If soaking emissions are not caused by leaks from the collecting 
main, notify a designated responsible party. The responsible party must 
determine whether the soaking emissions are due to incomplete coking. If 
incomplete coking is the cause of the soaking emissions, you must put 
the oven back on the collecting main until it is completely coked or you 
must ignite the emissions.
    (b) As provided in Sec. 63.6(g), you may request to use an 
alternative to the work practice standard in paragraph (a) of this 
section.



Sec. 63.7295  What requirements must I meet for quenching?

    (a) You must meet the requirements in paragraphs (a)(1) and (2) of 
this section for each quench tower and backup quench station at a new or 
existing coke oven battery.

naphthalene in the water used for quenching must not exceed the 
applicable site-specific limit approved by the permitting authority.
    (2) You must use acceptable makeup water, as defined in 
Sec. 63.7352, as makeup water for quenching.
    (b) For each quench tower at a new or existing coke oven battery and 
each backup quench station at a new coke oven battery, you must meet 
each of the requirements in paragraphs (b)(1) through (4) of this 
section.
    (1) You must equip each quench tower with baffles such that no more 
than 5 percent of the cross sectional area of the tower may be uncovered 
or open to the sky.
    (2) You must wash the baffles in each quench tower once each day 
that the tower is used to quench coke, except as specified in paragraphs 
(b)(2)(i) and (ii) of this section.
    (i) You are not required to wash the baffles in a quench tower if 
the highest measured ambient temperature remains less than 30 degrees 
Fahrenheit throughout that day (24-hour period). If the measured ambient 
temperature rises to 30 degrees Fahrenheit or more during the day, you 
must resume daily washing according to the schedule in your operation 
and maintenance plan.
    (ii) You must continuously record the ambient temperature on days 
that the baffles were not washed.
    (3) You must inspect each quench tower monthly for damaged or 
missing baffles and blockage.
    (4) You must initiate repair or replacement of damaged or missing 
baffles within 30 days and complete as soon as practicable.
    (c) As provided in Sec. 63.6(g), you may request to use an 
alternative to the work practice standards in paragraph (b) of this 
section.



Sec. 63.7296  What emission limitations must I meet for battery stacks?

    You must not discharge to the atmosphere any emissions from any 
battery stack at a new or existing by-product coke oven battery that 
exhibit an opacity greater than the applicable limit in paragraphs (a) 
and (b) of this section.
    (a) Daily average of 15 percent opacity for a battery on a normal 
coking cycle.
    (b) Daily average of 20 percent opacity for a battery on batterywide 
extended coking.

                 Operation and Maintenance Requirements



Sec. 63.7300  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

section.
    (b) To determine compliance with the emission limit for particulate 
matter from a control device applied to pushing emissions where a 
cokeside shed is the capture system, follow the test methods and 
procedures in paragraphs (b)(1) and (2) of this section. To determine 
compliance with a process-weighted mass rate of particulate matter (lb/
ton of coke) from a control device applied to pushing emissions where a 
cokeside shed is not used, follow the test methods and procedures in 
paragraphs (b)(1) through (4) of this section.
    (1) Determine the concentration of particulate matter according to 
the following test methods in appendix A to 40 CFR part 60.
    (i) Method 1 to select sampling port locations and the number of 
traverse points. Sampling sites 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 stack gas.

are engaged. Collect a minimum sample volume of 30 cubic feet of gas 
during each test run. Three valid test runs are needed to comprise a 
performance test. Each run must start at the beginning of a push and 
finish at the end of a push (i.e., sample for an integral number of 
pushes).

the 6-minute averages collected for periods during which the COMS is not 
out-of-control.



Sec. 63.7332  How do I monitor and collect data to demonstrate continuous compliance?

    (a) Except for monitor malfunctions, associated repairs, and 
required quality assurance or control activities (including as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times the affected source is operating.
    (b) 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 in fulfilling a minimum data availability requirement, if 
applicable. You must use all the data collected during all other periods 
in assessing compliance. 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.



Sec. 63.7333  How do I demonstrate continuous compliance with the emission limitations that apply to me?

    (a) For each control device applied to pushing emissions and subject 
to the emission limit in Sec. 63.7290(a), you must demonstrate 
continuous compliance by meeting the requirements in paragraphs (a)(1) 
and (2) of this section:

the initial or subsequent performance test and recording the results of 
each check.
    (2) If you elect the operating limit for volumetric flow rate in 
Sec. 63.7290(b)(3)(ii):
    (i) Maintaining the daily average volumetric flow rate at the inlet 
of the control device at or above the minimum level established during 
the initial or subsequent performance test; and
    (ii) Checking the volumetric flow rate at least every 8 hours to

Sec. 63.7334  How do I demonstrate continuous compliance with the work practice standards that apply to me?

    (a) For each by-product coke oven battery with vertical flues 
subject to the work practice standards for fugitive pushing emissions in 
Sec. 63.7291(a), you must demonstrate continuous compliance according to 
the requirements of paragraphs (a)(1) through (8) of this section:
    (1) Observe and record the opacity of fugitive emissions for four 
consecutive pushes per operating day, except you may make fewer or non-
consecutive observations as permitted by Sec. 63.7291(a)(3). Maintain 
records of the pushing schedule for each oven and records indicating the 
legitimate operational reason for any change in the pushing schedule 
according to Sec. 63.7291(a)(4).
    (2) Observe and record the opacity of fugitive emissions from each 
oven in a battery at least once every 90 days. If an oven cannot be 
observed during a 90-day period, observe and record the opacity of the 
first push of that oven following the close of the 90-day period that 
can be read in accordance with the procedures in paragraphs (a)(1) 
through (8) of this section.
    (3) Make all observations and calculations for opacity observations 
of fugitive pushing emissions in accordance with Method 9 in appendix A 
to 40 CFR part 60 using a Method 9 certified observer unless you have an 
approved alternative procedure under paragraph (a)(7) of this section.
    (4) Record pushing opacity observations at 15-second intervals as 
required in section 2.4 of Method 9 (appendix A to 40 CFR part 60). The 
requirement in section 2.4 of Method 9 for a minimum of 24 observations 
does not apply, and the data reduction requirements in section 2.5 of 
Method 9 do not apply. The requirement in Sec. 63.6(h)(5)(ii)(B) for 
obtaining at least 3 hours of observations (thirty 6-minute averages) to 
demonstrate initial compliance does not apply.
    (5) If fewer than six but at least four 15-second observations can 
be made, use the average of the total number of observations to 
calculate average opacity for the push. Missing one or more observations 
during the push (e.g., as the quench car passes behind a building) does 
not invalidate the observations before or after the interference for 
that push. However, a minimum of four 15-second readings must be made 
for a valid observation.
    (6) Begin observations for a push at the first detectable movement 
of the coke mass. End observations of a push when the quench car enters 
the quench tower.
    (i) For a battery without a cokeside shed, observe fugitive pushing 
emissions from a position at least 10 meters from the quench car that 
provides an unobstructed view and avoids interferences from the topside 
of the battery. This may require the observer to be positioned at an 
angle to the quench car rather than perpendicular to it. Typical 
interferences to avoid include emissions from open standpipes and 
charging. Observe the opacity of emissions above the battery top with 
the sky as the background where possible. Record the oven number of any 
push not observed because of obstructions or interferences.
    (ii) For a battery with a cokeside shed, the observer must be in a 
position that provides an unobstructed view and avoids interferences 
from the topside of the battery. Typical interferences to avoid include 
emissions from open standpipes and charging. Observations must include 
any fugitive emissions that escape from the top of the shed, from the 
ends of the shed, or from the area where the shed is joined to the 
battery. If the observer does not

[[Page 719]]

have a clear view to identify when a push starts or ends, a second 
person can be positioned to signal the start or end of the push and 
notify the observer when to start or end the observations. Radio 
communications with other plant personnel (e.g., pushing ram operator or 
quench car operator) may also serve to notify the observer of the start 
or end of a push. Record the oven number of any push not observed 
because of obstructions or interferences.
    (iii) You may reposition after the push to observe emissions during 
travel if necessary.
    (7) If it is infeasible to implement the procedures in paragraphs 
(a)(1) through (6) of this section for an oven due to physical 
obstructions, nighttime pushes, or other reasons, you may apply to your 
permitting authority for permission to use an alternative procedure. The 
application must provide a detailed explanation of why it is infeasible 
to use the procedures in paragraphs (a)(1) through (6) of this section, 
identify the oven and battery numbers, and describe the alternative 
procedure. An alternative procedure must identify whether the coke in 
that oven is not completely coked, either before, during, or after an 
oven is pushed.
    (8) For each oven observed that exceeds an opacity of 30 percent for 
any short battery or 35 percent for any tall battery, you must take 
corrective action and/or increase the coking time in accordance with 
Sec. 63.7291(a). Maintain records documenting conformance with the 
requirements in Sec. 63.7291(a).
    (b) For each by-product coke oven battery with horizontal flues 
subject to the work practice standards for fugitive pushing emissions in 
Sec. 63.7292(a), you must demonstrate continuous compliance by having 
met the requirements of paragraphs (b)(1) through (3) of this section:
    (1) Measuring and recording the temperature of all flues on two 
ovens per day within 2 hours before the oven's scheduled pushing time 
and ensuring that the temperature of each oven is measured and recorded 
at least once every month;
    (2) Recording the time each oven is charged and pushed and 
calculating and recording the net coking time for each oven; and
    (3) Increasing the coking time for each oven that falls below the 
minimum flue temperature trigger established for that oven's coking time 
in the written plan required in Sec. 63.7292(a)(1), assigning the oven 
to the oven-directed program, and recording all relevant information 
according to the requirements in Sec. 63.7292(a)(4) including, but not 
limited to, daily pushing schedules, diagnostic procedures, corrective 
actions, and oven repairs.
    (c) For each non-recovery coke oven battery subject to the work 
practice standards in Sec. 63.7293(a), you must demonstrate continuous 
compliance by maintaining records that document each visual inspection 
of an oven prior to pushing and that the oven was not pushed unless 
there was no smoke in the open space above the coke bed and there was an 
unobstructed view of the door on the opposite side of the oven.
    (d) For each by-product coke oven battery subject to the work 
practice standard for soaking in Sec. 63.7294(a), you must demonstrate 
continuous compliance by maintaining records that document conformance 
with requirements in Sec. 63.7294(a)(1) through (5).
    (e) For each coke oven battery subject to the work practice standard 
for quenching in Sec. 63.7295(b), you must demonstrate continuous 
compliance according to the requirements of paragraphs (e)(1) through 
(3) of this section:
    (1) Maintaining baffles in each quench tower such that no more than 
5 percent of the cross-sectional area of the tower is uncovered or open 
to the sky as required in Sec. 63.7295(b)(1);
    (2) Maintaining records that document conformance with the washing, 
inspection, and repair requirements in Sec. 63.7295(b)(2), including 
records of the ambient temperature on any day that the baffles were not 
washed; and
    (3) Maintaining records of the source of makeup water to document 
conformance with the requirement for acceptable makeup water in 
Sec. 63.7295(a)(2).

sounds, and for each valid alarm, the time you initiated corrective 
action, the corrective action(s) taken, and the date on which corrective 
action is completed.
    (c) To demonstrate continuous compliance with the operation and 
maintenance requirements for a baghouse applied to pushing emissions 
from a coke oven battery in Sec. 63.7331(a), you must inspect and 
maintain each baghouse according to the requirements in 
Sec. 63.7331(a)(1) through (8) and record all information needed to 
document conformance with these requirements. If you increase or 
decrease the sensitivity of the bag leak detection system beyond the 
limits specified in Sec. 63.7331(a)(6), you must include a copy of the 
required written certification by a responsible official in the next 
semiannual compliance report.
    (d) You must maintain a current copy of the operation and 
maintenance plans required in Sec. 63.7300(b) and (c) onsite and 
available for inspection upon request. You must keep the plans for the 
life of the affected source or until the affected source is no longer 
subject to the requirements of this subpart.



Sec. 63.7336  What other requirements must I meet to demonstrate continuous compliance?

    (a) Deviations. You must report each instance in which you did not 
meet each emission limitation in this subpart that applies to you. This 
includes periods of startup, shutdown, and malfunction. You must also 
report each instance in which you did not meet each work practice 
standard or operation and maintenance requirement in this subpart that 
applies to you. These instances are deviations from the emission 
limitations (including operating limits), work practice standards, and 
operation and maintenance requirements in this subpart. These deviations 
must be reported according to the requirements in Sec. 63.7341.
    (b) Startup, shutdowns, and malfunctions. During periods of startup,

    (d) Immediate startup, shutdown, and malfunction report. If you had 
a startup, shutdown, or malfunction during the semiannual reporting 
period that was not consistent with your startup, shutdown, and 
malfunction plan, you must submit an immediate startup, shutdown, and 
malfunction report according to the requirements in 
Sec. 63.10(d)(5)(ii).
    (e) Part 70 monitoring report. If you have obtained a title V 
operating permit for an affected source pursuant to 40 CFR part 70 or 40 
CFR part 71, you must report all deviations as defined in this subpart 
in the semiannual monitoring report required by 40 CFR 
70.6(a)(3)(iii)(A) or 40 CFR 71.6(a)(3)(iii)(A). If you submit a 
compliance report for an affected source along with, or as part of, the 
semiannual monitoring report required by 40 CFR 70.6(a)(3)(iii)(A) or 40 
CFR 71.6(a)(3)(iii)(A), and the compliance report includes all the 
required information concerning deviations from any emission limitation 
or work practice standard in this subpart, submission of the compliance 
report satisfies any obligation to report the same deviations in the 
semiannual monitoring report. However, submission of a compliance report 
does not otherwise affect any obligation you may have to report 
deviations from permit requirements to your permitting authority.

are not recovered.
    Oven means a chamber in the coke oven battery in which coal 
undergoes destructive distillation to produce coke.
    Pushing means the process of removing the coke from the oven. 
Pushing begins with the first detectable movement of the coke mass and 
ends when the quench car enters the quench tower.

through an open standpipe prior to pushing and ends when the coke begins 
to be pushed from the oven.
    Soaking emissions means the discharge from an open standpipe during 
soaking of visible emissions due to either incomplete coking or leakage 
into the standpipe from the collecting main.
    Standpipe means an apparatus on the oven that provides a passage for

Subpart FFFFF--National Emission Standards for Hazardous Air Pollutants 
         for Integrated Iron and Steel Manufacturing Facilities

    Source: 68 FR 27663, May 20, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.7780  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for integrated iron and steel manufacturing 
facilities. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with all applicable emission 
limitations and operation and maintenance requirements in this subpart.



Sec. 63.7781  Am I subject to this subpart?

    You are subject to this subpart if you own or operate an integrated 
iron and steel manufacturing facility that is (or is part of) a major 
source of hazardous air pollutants (HAP) emissions. Your integrated iron 
and steel manufacturing facility is a major source of HAP if it emits or 
has the potential to emit any single HAP at a rate of 10 tons or more 
per year or any combination of HAP at a rate of 25 tons or more per 
year.



Sec. 63.7782  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new and existing affected source at 
your integrated iron and steel manufacturing facility.
    (b) The affected sources are each new or existing sinter plant, 
blast furnace, and basic oxygen process furnace (BOPF) shop at your 
integrated iron and steel manufacturing facility.
    (c) This subpart covers emissions from the sinter plant windbox 
exhaust, discharge end, and sinter cooler; the blast furnace casthouse; 
and the BOPF shop including each individual BOPF and shop ancillary 
operations (hot metal transfer, hot metal desulfurization, slag 
skimming, and ladle metallurgy).
    (d) A sinter plant, blast furnace, or BOPF shop at your integrated 
iron and steel manufacturing facility is existing if you commenced 
construction or reconstruction of the affected source before July 13, 
2001.
    (e) A sinter plant, blast furnace, or BOPF shop at your integrated 
iron and steel manufacturing facility is new if you commence 
construction or reconstruction of the affected source on or after July 
13, 2001. An affected source is reconstructed if it meets the definition 
of reconstruction in Sec. 63.2.



Sec. 63.7783  When do I have to comply with this subpart?

    (a) If you have an existing affected source, you must comply with 
each emission limitation and operation and maintenance requirement in 
this subpart that applies to you no later than May 22, 2006.
    (b) If you have a new affected source and its initial startup date 
is on or before May 20, 2003, then you must comply with each emission 
limitation and operation and maintenance requirement in this subpart 
that applies to you by May 20, 2003.
    (c) If you have a new affected source and its initial startup date 
is after May 20, 2003, you must comply with each emission limitation and 
operation and maintenance requirement in this subpart that applies to 
you upon initial startup.
    (d) If your integrated iron and steel manufacturing facility is not 
a major source and becomes a major source of HAP, the following 
compliance dates apply to you.
    (1) Any portion of the existing integrated iron and steel 
manufacturing facility that becomes a new affected source or a new 
reconstructed source must be in compliance with this subpart upon 
startup.
    (2) All other parts of the integrated iron and steel manufacturing 
facility must be in compliance with this subpart no later than 2 years 
after it becomes a major source.

[[Page 729]]

    (e) You must meet the notification and schedule requirements in 
Sec. 63.7840. Several of these notifications must be submitted before 
the compliance date for your affected source.

                          Emission Limitations



Sec. 63.7790  What emission limitations must I meet?

    (a) You must meet each emission limit and opacity limit in Table 1 
to this subpart that applies to you.
    (b) You must meet each operating limit for capture systems and 
control devices in paragraphs (b)(1) through (3) of this section that 
applies to you.
    (1) You must operate each capture system applied to emissions from a 
sinter plant discharge end or blast furnace casthouse or to secondary 
emissions from a BOPF at or above the lowest value or settings

                 Operation and Maintenance Requirements



Sec. 63.7800  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 or control device 
subject to an operating limit in Sec. 63.7790(b). Each plan must address 
the elements in paragraphs (b)(1) through (5) of this section.
    (1) Monthly inspections of the equipment that is important to the 
performance of the total capture system (e.g., pressure sensors, 
dampers, and damper switches). This inspection must include observations 
of the physical appearance of the equipment (e.g., presence of holes in 
ductwork or hoods, flow constrictions caused by dents or accumulated 
dust in the ductwork, and fan erosion). The operation and maintenance 
plan also must include requirements to repair any defect or deficiency 
in the capture system before the next scheduled inspection.
    (2) Preventative maintenance for each control device, including a 
preventative maintenance schedule that is consistent with the 
manufacturer's instructions for routine and long-term maintenance.
    (3) Operating limits for each capture system applied to emissions 
from a sinter plant discharge end or blast furnace casthouse, or to 
secondary emissions from a BOPF. You must establish the

[[Page 730]]

operating limits according to the requirements in paragraphs (b)(3)(i) 
through (iii) of this section.
    (i) Select operating limit parameters appropriate for the capture 
system design that are representative and reliable indicators of the 
performance of the capture system. 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 emissions, including revised settings 
for seasonal variations. 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 the control device to which the capture system is vented, fan 
motor amperage, or static pressure.
    (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 the process 
operation. If your operation allows for more than one process to be 
operating simultaneously, designate the value or setting for the 
parameter at which the capture system operates during each possible 
configuration that you may operate.
    (iii) Include documentation in your 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 operating during 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 of Sec. 63.7830(a), and the 
data used to set the value or setting for the parameter for each of your 
process configurations.
    (4) Corrective action procedures for bag leak detection systems. In 
the event a bag leak detection system alarm is triggered, you must 
initiate corrective action 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:
    (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; 
and
    (5) Procedures for determining and recording the daily sinter plant 
production rate in tons per hour.

includes both top and bottom blown furnaces, but does not include argon 
oxygen decarburization furnaces.
    Basic oxygen process furnace shop means the place where steelmaking 
operations that begin with the transfer of molten iron (hot metal) from 
the torpedo car and end prior to casting the molten steel, including hot 
metal transfer, desulfurization, slag skimming, refining in a basic 
oxygen process furnace, and ladle metallurgy occur.
    Basic oxygen process furnace shop ancillary operations means the 
processes where hot metal transfer, hot metal desulfurization, slag 
skimming, and ladle metallurgy occur.
    Blast furnace means a furnace used for the production of molten iron 
from iron ore and other iron bearing materials.
    Bottom-blown furnace means any basic oxygen process furnace in which 
oxygen and other combustion gases are introduced into the bath of molten 
iron through tuyeres in the bottom of the vessel or through tuyeres in 
the bottom and sides of the vessel.

subpart, including but not limited to any emission limitation (including 
operating limits) or operation and maintenance requirement;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limitation in this subpart during 
startup, shutdown, or malfunction, regardless of whether or not such 
failure is permitted by this subpart.
    Discharge end means the place where those operations conducted 
within the sinter plant starting at the discharge of the sintering 
machine's traveling grate including (but not limited to) hot sinter 
crushing, screening, and transfer operations occur.
    Emission limitation means any emission limit, opacity limit, or 
operating limit.
    Hot metal transfer station means the location in a basic oxygen 
process furnace shop where molten iron (hot metal) is transferred from a 
torpedo car or hot metal car used to transport hot metal from the blast 
furnace casthouse to a holding vessel or ladle in the basic oxygen 
process furnace shop. This location also is known as the reladling 
station or ladle transfer station.
    Integrated iron and steel manufacturing facility means an 
establishment engaged in the production of steel from iron ore.
    Ladle metallurgy means a secondary steelmaking process that is 
performed typically in a ladle after initial refining in a basic oxygen 
process furnace to adjust or amend the chemical and/or mechanical 
properties of steel.
    Primary emissions means particulate matter emissions from the basic 
oxygen process furnace generated during the steel production cycle which 
are captured and treated in the furnace's primary emission control 
system.
    Primary emission control system means the combination of equipment 
used for the capture and collection of primary emissions (e.g., an open 
hood capture system used in conjunction with an electrostatic 
precipitator or a closed hood system used in conjunction with a 
scrubber).
    Primary oxygen blow means the period in the steel production cycle 
of a basic oxygen process furnace during which oxygen is blown through 
the molten iron bath by means of a lance inserted from the top of the 
vessel (top-blown) or through tuyeres in the bottom and/or sides of the 
vessel (bottom-blown).
    Responsible official means responsible official as defined in 
Sec. 63.2.
    Secondary emissions means particulate matter emissions that are not 
controlled by a primary emission control system, including emissions 
that escape from open and closed hoods, lance hole openings, and gaps or 
tears in ductwork to the primary emission control system.
    Secondary emission control system means the combination of equipment 
used for the capture and collection of secondary emissions from a basic 
oxygen process furnace.

product that is transferred from the discharge end through contact with 
large volumes of induced or forced draft air.
    Sinter plant means the machine used to produce a fused clinker-like 
aggregate or sinter of fine iron-bearing materials suited for use in a 
blast furnace. The machine is composed of a continuous traveling grate 
that conveys a bed of ore fines and other finely divided iron-bearing 
material and fuel (typically coke breeze), a burner at the feed end of 
the grate for ignition, and a series of downdraft windboxes along the

[[Page 745]]

length of the strand to support downdraft combustion and heat sufficient 
to produce a fused sinter product.
    Skimming station means the locations inside a basic oxygen process 
furnace shop where slag is removed from the top of the molten metal 
bath.
    Steel production cycle means the operations conducted within the 
basic oxygen process furnace shop that are required to produce each 
batch of steel. The following operations are included: scrap charging, 
preheating (when done), hot metal charging, primary oxygen blowing, 
sampling, (vessel turndown and turnup), additional oxygen blowing (when 
done), tapping, and deslagging. The steel production cycle begins when 
the scrap is charged to the furnace and ends after the slag is emptied 
from the vessel into the slag pot.
    Top-blown furnace means any basic oxygen process furnace in which 
oxygen is introduced into the bath of molten iron by means of an oxygen 
lance inserted from the top of the vessel.
    Windboxes means the compartments that provide for a controlled

                    Subparts GGGGG--IIIII [Reserved]



  



Subpart JJJJJ--National Emission Standards for Hazardous Air Pollutants 
          for Brick and Structural Clay Products Manufacturing

    Source: 68 FR 26722, May 16, 2003, unless otherwise note.

                        What This Subpart Covers



Sec. 63.8380  What is the purpose of this subpart?

    This subpart establishes national emission limitations for hazardous 
air pollutants (HAP) emitted from brick and structural clay products 
(BSCP) manufacturing facilities. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limitations.



Sec. 63.8385  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a BSCP 
manufacturing facility that is, is located at, or is part of, a major 
source of HAP emissions according to the criteria in paragraphs (a) and 
(b) of this section.
    (a) A BSCP manufacturing facility is a plant site that manufactures 
brick (including, but not limited to, face brick, structural brick, and 
brick pavers); clay pipe; roof tile; extruded floor and wall tile; and/
or other extruded, dimensional clay products. Brick and structural clay 
products manufacturing facilities typically process raw clay and shale, 
form the processed materials into bricks or shapes, and dry and fire the 
bricks or shapes.
    (b) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.07 megagrams (10 tons) or more per year or any combination of HAP 
at a rate of 22.68 megagrams (25 tons) or more per year.



Sec. 63.8390  What parts of my plant does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed 
affected source at a BSCP manufacturing facility.
    (b) The existing affected source is an existing tunnel kiln with a 
design capacity equal to or greater than 9.07 megagrams per hour (Mg/hr) 
(10 tons per hour (tph)) of fired product according to paragraphs (b)(1) 
through (3) of this section. For the remainder of this subpart, a tunnel 
kiln with a design capacity equal to or greater than 9.07 Mg/hr (10 tph) 
of fired product will be called a large tunnel kiln, and a tunnel kiln 
with a design capacity less than 9.07 Mg/hr (10 tph) of fired product 
will be called a small tunnel kiln.
    (1) For existing tunnel kilns that do not have sawdust dryers, the 
kiln exhaust process stream (i.e., the only process stream) is subject 
to the requirements of this subpart.
    (2) For existing tunnel kilns that ducted exhaust to sawdust dryers 
prior to July 22, 2002, only the kiln exhaust process stream (i.e., the 
process stream that exhausts directly to the atmosphere or to an air 
pollution control device (APCD)) is subject to the requirements of this 
subpart. As such, any process stream that is ducted to a sawdust dryer 
is not subject to these requirements.
    (3) For existing tunnel kilns that first ducted exhaust to sawdust 
dryers on or after July 22, 2002, all of the exhaust (i.e., all process 
streams) is subject to the requirements of this subpart.
    (c) An existing small tunnel kiln whose design capacity is increased 
such that it is equal to or greater than 9.07 Mg/hr (10 tph) of fired 
product is subject to the requirements of this subpart.
    (d) An existing tunnel kiln with a federally enforceable permit 
condition that restricts kiln operation to less than 9.07 Mg/hr (10 tph) 
of fired product on a 12-month rolling average basis is not subject to 
the requirements of this subpart.
    (e) Each new or reconstructed tunnel kiln is an affected source 
regardless of design capacity. All process streams from each new or 
reconstructed tunnel

[[Page 752]]

kiln are subject to the requirements of this subpart.
    (f) Kilns that are used exclusively for research and development 
(R&D) and are not used to manufacture products for commercial sale, 
except in a de minimis manner, are not subject to the requirements of 
this subpart.
    (g) Kilns that are used exclusively for setting glazes on previously 
fired products are not subject to the requirements of this subpart.
    (h) A source is a new affected source if construction of the 
affected source began after July 22, 2002, and you met the applicability 
criteria at the time you began construction.
    (i) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2, except as provided in paragraphs (i)(1) and (i)(2) 
of this section.
    (1) It is not technologically and economically feasible for an 
existing small tunnel kiln whose design capacity is increased such that 
it is equal to or greater than 9.07 Mg/hr (10 tph) of fired product to 
meet the relevant standards (i.e., new source maximum achievable control 
technology (MACT)) by retrofitting with a dry lime injection fabric 
filter (DIFF), dry lime scrubber/fabric filter (DLS/FF), or wet scrubber 
(WS).
    (2) It is not technologically and economically feasible for an 
existing large dry limestone adsorber (DLA)-controlled kiln to meet the 
relevant standards by retrofitting with a DIFF, DLS/FF, or WS.
    (j) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.8395  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section.
    (1) If the initial startup of your affected source is before May 16, 
2003, then you must comply with the applicable emission limitations in 
Tables 1 and 2 to this subpart no later than May 16, 2003.
    (2) If the initial startup of your affected source is after May 16, 
2003, then you must comply with the applicable emission limitations in 
Tables 1 and 2 to this subpart upon initial startup of your affected 
source.
    (b) If you have an existing affected source, you must comply with 
the applicable emission limitations in Tables 1 and 2 to this subpart no 
later than May 16, 2003.
    (c) If you have an existing area source that increases its emissions 
or its potential to emit such that it becomes a major source of HAP, you 
must be in compliance with this subpart according to paragraphs (c)(1) 
and (2) of this section.
    (1) Any portion of the existing facility 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 existing facility must be in compliance 
with this subpart by 3 years after the date the area source becomes a 
major source.
    (d) If you have a new area source (i.e., an area source for which 
construction or reconstruction commenced after July 22, 2002) that 
increases its emissions or its potential to emit such that it becomes a 
major source of HAP, you must be in compliance with this subpart upon 
initial startup of your affected source as a major source.
    (e) You must meet the notification requirements in Sec. 63.8480 
according to the schedule in Sec. 63.8480 and in 40 CFR part 63, subpart 
A. Some of the notifications must be submitted before you are required 
to comply with the emission limitations in this subpart.

                          Emission Limitations



Sec. 63.8405  What emission limitations must I meet?

    (a) You must meet each emission limit in Table 1 to this subpart 
that applies to you.
    (b) You must meet each operating limit in Table 2 to this subpart 
that applies to you.



Sec. 63.8410  What are my options for meeting the emission limitations?

    To meet the emission limitations in Tables 1 and 2 to this subpart, 
you must use one or more of the options listed in paragraphs (a) and (b) 
of this section.

[[Page 753]]

    (a) Emissions control system. Use an emissions capture and 
collection system and an APCD and demonstrate that the resulting 
emissions or emissions reductions meet the emission limits in Table 1 to 
this subpart, and that the capture and collection system and APCD meet 
the applicable operating limits in Table 2 to this subpart.
    (b) Process changes. Use low-HAP raw materials or implement 
manufacturing process changes and demonstrate that the resulting

    (5) The bag leak detection system must be equipped with an audible 
alarm system that will sound automatically when an increase in relative 
PM emissions over a preset level is detected. The alarm must be located 
where it is easily heard by plant operating personnel.
    (6) For positive pressure fabric filter systems, a bag leak detector 
must be installed in each baghouse compartment or cell.
    (7) For negative pressure or induced air fabric filters, the bag 
leak detector must be installed downstream of the fabric filter.
    (8) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (9) The baseline output must be established by adjusting the range 
and the averaging period of the device and establishing the alarm set 
points and the alarm delay time according to section 5.0 of the ``Fabric 
Filter Bag Leak Detection Guidance.''
    (10) Following initial adjustment of the system, the sensitivity or 
range, averaging period, alarm set points, or alarm delay time may not 
be adjusted except as detailed in your OM&M plan. In no case may the 
sensitivity be increased by more than 100 percent or decreased more than 
50 percent over a 365-day period unless such adjustment follows a 
complete fabric filter inspection that demonstrates that the fabric 
filter is in good operating condition. Record each adjustment.
    (11) Record the results of each inspection, calibration, and 
validation check.

[[Page 758]]

                   Continuous Compliance Requirements



Sec. 63.8465  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for periods of monitor malfunctions, associated repairs, 
and required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times that the affected source is operating. This 
includes periods of startup, shutdown, malfunction, and routine control 
device maintenance as specified in Sec. 63.8420(e) when the affected 
source is operating.
    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities for purposes of calculating data 
averages. A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitoring system to provide valid 
data. Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. You must use all the valid data 
collected during all other periods in assessing compliance. Any 
averaging period for which you do not have valid monitoring data and 
such data are required constitutes a deviation from the monitoring 
requirements.



Sec. 63.8470  How do I demonstrate continuous compliance with the emission limitations?

    (a) You must demonstrate continuous compliance with each emission 
limit and operating limit in Tables 1 and 2 to this subpart that applies 
to you according to the methods specified in Table 5 to this subpart.
    (b) For each affected kiln that is equipped with an APCD that is not 
addressed in Table 2 to this subpart, or that is using process changes 
as a means of meeting the emission limits in Table 1 to this subpart, 
you must demonstrate continuous compliance with each emission limit in 
Table 1 to this subpart, and each operating limit established as 
required in Sec. 63.8445(i)(2) according to the methods specified in 
your approved alternative monitoring procedures request, as described in 
Secs. 63.8445(i)(1) and 63.8(f).
    (c) You must report each instance in which you did not meet each 
emission limit and each operating limit in this subpart that applies to 
you. This includes periods of startup, shutdown, malfunction, and 
routine control device maintenance. These instances are deviations from 
the emission limitations in this subpart. These deviations must be 
reported according to the requirements in Sec. 63.8485.
    (d) During periods of startup, shutdown, and malfunction, you must 
operate according to your SSMP.
    (e) Consistent with Secs. 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 according to an SSMP that satisfies the requirements 
of Sec. 63.6(e) and your OM&M plan. 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).
    (f) Deviations that occur during periods of control device 
maintenance covered by an approved routine control device maintenance 
exemption according to Sec. 63.8420(e) are not violations if you 
demonstrate to the Administrator's satisfaction that you were operating 
in accordance with the approved routine control device maintenance 
exemption.
    (g) You must demonstrate continuous compliance with the operating 
limits in Table 2 to this subpart for visible emissions (VE) from tunnel 
kilns equipped with DLA, DIFF, or DLS/FF by monitoring VE at each kiln 
stack according to the requirements in paragraphs (g)(1) through (3) of 
this section.
    (1) Perform daily VE observations of each kiln stack according to 
the procedures of Method 22 of 40 CFR part 60, appendix A. You must 
conduct the Method 22 test while the affected source is operating under 
normal conditions. The duration of each Method 22 test must be at least 
15 minutes.

[[Page 759]]

    (2) If VE are observed during any daily test conducted using Method 
22 of 40 CFR part 60, appendix A, you must promptly initiate and 
complete corrective actions according to your OM&M plan. If no VE are 
observed in 30 consecutive daily Method 22 tests for any kiln stack, you 
may decrease the frequency of Method 22 testing from daily to weekly for 
that kiln stack. If VE are observed during any weekly test, you must 
promptly initiate and complete corrective actions according to your OM&M 
plan, resume Method 22 testing of that kiln stack on a daily basis, and 
maintain that schedule until no VE are observed in 30 consecutive daily 
tests, at which time you may again decrease the frequency of Method 22 
testing to a weekly basis.
    (3) If VE are observed during any test conducted using Method 22 of 
40 CFR part 60, appendix A, you must report these deviations by 
following the requirements in Sec. 63.8485.

limited to, an instrument that operates on triboelectric, light-
scattering, light-transmittance, or other effects to monitor relative PM 
loadings.
    Brick and structural clay products (BSCP) manufacturing facility 
means a plant site that manufactures brick (including, but not limited 
to, face brick, structural brick, and brick pavers); clay pipe; roof 
tile; extruded floor and wall tile; and/or other extruded, dimensional 
clay products. Brick and structural clay products manufacturing 
facilities typically process raw clay and shale, form the processed 
materials into bricks or shapes, and dry and fire the bricks or shapes.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limitation 
(including any operating limit) or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart for any affected source 
required to obtain such a permit; or
    (3) Fails to meet any emission limitation (including any operating 
limit) or work practice standard in this subpart during startup, 
shutdown, or malfunction, regardless of whether or not such failure is 
permitted by this subpart.
    Dry lime injection fabric filter (DIFF) means an APCD that includes 
continuous injection of hydrated lime or other sorbent into a duct or 
reaction chamber followed by a fabric filter.
    Dry lime scrubber/fabric filter (DLS/FF) means an APCD that includes 
continuous injection of humidified hydrated lime or other sorbent into a 
reaction chamber followed by a fabric filter. These systems typically 
include recirculation of some of the sorbent.
    Dry limestone adsorber (DLA) means an APCD that includes a limestone 
storage bin, a reaction chamber that is essentially a packed tower 
filled with limestone, and may or may not include a peeling drum that 
mechanically scrapes reacted limestone to regenerate the stone for 
reuse.
    Emission limitation means any emission limit or operating limit.
    Fabric filter means an APCD used to capture PM by filtering a gas 
stream through filter media; also known as a baghouse.
    Initial startup means:
    (1) For a new or reconstructed tunnel kiln controlled with a DLA, 
and for a tunnel kiln that would be considered reconstructed but for 
Sec. 63.8390(i)(1) or Sec. 63.8390(i)(2), the time at which the 
temperature in the kiln first reaches 260 [deg]C (500 [deg]F) and the 
kiln contains product; or
    (2) For a new or reconstructed tunnel kiln controlled with a DIFF, 
DLS/FF, or WS, the time at which the kiln first reaches a level of 
production that is equal to 75 percent of the kiln design capacity or 12 
months after the affected source begins firing BSCP, whichever is 
earlier.
    Kiln exhaust process stream means the portion of the exhaust from a 
tunnel kiln that exhausts directly to the atmosphere (or to an APCD), 
rather than to a sawdust dryer.
    Large tunnel kiln means a tunnel kiln (existing, new, or 
reconstructed) with a design capacity equal to or greater than 9.07 Mg/
hr (10 tph) of fired product.
    Particulate matter (PM) means, for purposes of this subpart, 
emissions of

[[Page 764]]

PM that serve as a measure of total particulate emissions, as measured 
by Method 5 (40 CFR part 60, appendix A), and as a surrogate for metal 
HAP contained in the particulates including, but not limited to, 
antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, 
manganese, mercury, nickel, and selenium.
    Plant site means all contiguous or adjoining property that is under 
common control, including properties that are separated only by a road 
or other public right-of-way. Common control includes properties that 
are owned, leased, or operated by the same entity, parent entity, 
subsidiary, or any combination thereof.
    Research and development kiln means any kiln whose purpose is to 
conduct research and development for new processes and products and is 
not engaged in the manufacture of products for commercial sale, except 
in a de minimis manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Small tunnel kiln means a tunnel kiln (existing, new, or 
reconstructed) with a design capacity less than 9.07 Mg/hr (10 tph) of 
fired product.
    Startup means the setting in operation of an affected source and 
starting the production process.
    Tunnel kiln means any continuous kiln that is used to fire BSCP. 
Some tunnel kilns have two process streams, including a process stream 
that exhausts directly to the atmosphere or to an APCD, and a process 
stream in which the kiln exhaust is ducted to a sawdust dryer where it 
is used to dry sawdust before being emitted to the atmosphere.
    Tunnel kiln design capacity means the maximum amount of brick, in Mg 
(tons), that a kiln is designed to produce in one year divided by the 
number of hours in a year (8,760 hours). If a kiln is modified to 
increase the capacity, the design capacity is considered to be the 
capacity following modifications.
    Wet scrubber (WS) means an APCD that uses water, which may include 
caustic additives or other chemicals, as the sorbent. Wet scrubbers may 
use any of various design mechanisms to increase the contact between 
exhaust gases and the sorbent.

Subpart KKKKK--National Emission Standards for Hazardous Air Pollutants 
                     for Clay Ceramics Manufacturing

    Source: 68 FR 26738, May 16, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.8530  What is the purpose of this subpart?

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



Sec. 63.8535  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a clay 
ceramics manufacturing facility that is, is located at, or is part of a 
major source of HAP emissions according to the criteria in paragraphs 
(a) and (b) of this section.
    (a) A clay ceramics manufacturing facility is a plant site that 
manufactures pressed floor tile, pressed wall tile, other pressed tile, 
or sanitaryware (e.g., sinks and toilets). Clay ceramics manufacturing 
facilities typically process clay, shale, and various additives; form 
the processed materials into tile or sanitaryware shapes; and dry and 
fire the ceramic products. Glazes are applied to many tile and 
sanitaryware products.
    (b) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.07 megagrams (10 tons) or more per year or any combination of HAP 
at a rate of 22.68 megagrams (25 tons) or more per year.



Sec. 63.8540  What parts of my plant does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed 
affected source at a clay ceramics manufacturing facility and to each 
affected source described in paragraphs (f)(1) or (f)(2) of this 
section.
    (b) Each existing, new, or reconstructed periodic kiln, tunnel kiln, 
and roller kiln is an affected source regardless of design capacity. 
Each source that meets the description in paragraphs (f)(1) or (f)(2) 
also is an affected source.
    (c) Kilns that are used exclusively for research and development 
(R&D) and are not used to manufacture products for commercial sale, 
except in a de minimis manner, are not subject to the requirements of 
this subpart.
    (d) Kilns that are used exclusively for setting glazes on previously 
fired products or for refiring are not subject to the requirements of 
this subpart.
    (e) A source is a new affected source if construction of the 
affected source began after July 22, 2002, and you met the applicability 
criteria at the time you began construction.
    (f) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2, except as provided in paragraphs (f)(1) and (f)(2) 
of this section.
    (1) It is not technologically and economically feasible for an 
existing tunnel kiln whose design capacity is less than 9.07 megagrams 
per hour (Mg/hr) (10 tons per hour (tph)) of fired product but is 
increased such that it is equal to or greater than 9.07 Mg/hr (10 tph) 
of fired product to meet the relevant standards (i.e., new source 
maximum achievable control technology (MACT)) by retrofitting with a dry 
lime injection fabric filter (DIFF), dry lime scrubber/fabric filter 
(DLS/FF), or wet scrubber (WS).
    (2) It is not technologically and economically feasible for an 
existing dry limestone adsorber (DLA)-controlled kiln whose design 
capacity is equal to or greater than 9.07 Mg/hr (10 tph) of fired 
product to meet the relevant standards by retrofitting with a DIFF, DLS/
FF, or WS.
    (g) An affected source is existing if it is not new or reconstructed 
and does not meet the descriptions provided in paragraphs (f)(1) and 
(f)(2) of this section.



Sec. 63.8545  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source or an 
affected

[[Page 776]]

source described in Sec. 63.8540(f)(1) or Sec. 63.8540(f)(2), you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section.
    (1) If the initial startup of your affected source is before May 16, 
2003, then you must comply with the applicable emission limitations and 
work practice standards in Tables 1, 2, and 3 to this subpart no later 
than May 16, 2003.
    (2) If the initial startup of your affected source is after May 16, 
2003, then you must comply with the applicable emission limitations and 
work practice standards in Tables 1, 2, and 3 to this subpart upon 
initial startup of your affected source.
    (b) If you have an existing affected source, you must comply with 
the work practice standards for existing sources in Table 3 to this 
subpart no later than May 16, 2003.
    (c) If you have an existing area source that increases its emissions 
or its potential to emit such that it becomes a major source of HAP by 
adding a new affected source or by reconstructing, you must be in 
compliance with this subpart upon initial startup of your affected 
source as a major source.
    (d) If you have a new area source (i.e., an area source for which 
construction or reconstruction was commenced after July 22, 2002) that 
increases its emissions or its potential to emit such that it becomes a 
major source of HAP, you must be in compliance with this subpart upon 
initial startup of your affected source as a major source.
    (e) You must meet the notification requirements in Sec. 63.8630 
according to the schedule in Sec. 63.8630 and in 40 CFR part 63, subpart

spaced data values (or at least 75 percent if you collect more than four 
data values per hour) for that hour (not including startup, shutdown, 
malfunction, out-of-control periods, or periods of routine control 
device maintenance covered by a routine control device maintenance 
exemption as specified in Sec. 63.8570(e)).
    (3) Determine and record the 3-hour block averages of all recorded 
readings, calculated after every 3 hours of operation as the average of 
the previous 3 operating hours. To calculate the average for each 3-hour 
average period, you must have at least 75 percent of the recorded 
readings for that period (not including startup, shutdown, malfunction, 
out-of-control periods, or periods of routine control device maintenance 
covered by a routine control device maintenance exemption as specified 
in Sec. 63.8570(e)).
    (4) Record the results of each inspection, calibration, and 
validation check.
    (5) At all times, maintain the monitoring equipment including, but 
not limited to, maintaining necessary parts for routine repairs of the

meet the requirements in Secs. 63.8595(i) and 63.8(f).



Sec. 63.8605  How do I demonstrate initial compliance with the emission limitations and work practice standards?

    (a) You must demonstrate initial compliance with each emission 
limitation and work practice standard that applies to you according to 
Table 5 to this subpart.
    (b) You must establish each site-specific operating limit in Table 2 
to this subpart that applies to you according to the requirements in 
Sec. 63.8595 and Table 4 to this subpart.
    (c) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.8630(e).

                   Continuous Compliance Requirements



Sec. 63.8615  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.
    (b) Except for periods of monitor malfunctions, associated repairs, 
and required quality assurance or control activities (including, as 
applicable, calibration checks and required zero and span adjustments), 
you must monitor continuously (or collect data at all required 
intervals) at all times that the affected source is operating. This 
includes periods of startup, shutdown, malfunction, and routine control 
device maintenance as specified in Sec. 63.8570(e) when the affected 
source is operating.

[[Page 782]]

    (c) You may not use data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities for purposes of calculating data 
averages. A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the monitoring system to provide valid 
data. Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. You must use all the valid data 
collected during all other periods in assessing compliance. Any 
averaging period for which you do not have valid monitoring data and 
such data are required constitutes a deviation from the monitoring 
requirements.



Sec. 63.8620  How do I demonstrate continuous compliance with the emission limitations and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limit, operating limit, and work practice standard in Tables 1, 2, and 3 
to this subpart that applies to you according to the methods specified 
in Table 6 to this subpart.
    (b) For each kiln that is subject to the emission limits specified 
in Table 1 to this subpart and is equipped with an APCD that is not 
addressed in Table 2 to this subpart, or that is using process changes 
as a means of meeting the emission limits in Table 1 to this subpart, 
you must demonstrate continuous compliance with each emission limit in 
Table 1 to this subpart, and each operating limit established as 
required in Sec. 63.8595(i)(2) according to the methods specified in 
your approved alternative monitoring procedures request, as described in 
Secs. 63.8595(i)(1) and 63.8(f).
    (c) You must report each instance in which you did not meet each 
emission limit and operating limit in this subpart that applies to you. 
This includes periods of startup, shutdown, malfunction, and routine 
control device maintenance. These instances are deviations from the 
emission limitations in this subpart. These deviations must be reported 
according to the requirements in Sec. 63.8635.
    (d) During periods of startup, shutdown, and malfunction, you must 
operate according to your SSMP.
    (e) Consistent with Secs. 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 according to an SSMP that satisfies the requirements 
of Sec. 63.6(e) and your OM&M plan. 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).
    (f) Deviations that occur during periods of control device 
maintenance covered by an approved routine control device maintenance 
exemption according to Sec. 63.8570(e) are not violations if you 
demonstrate to the Administrator's satisfaction that you were operating 
in accordance with the approved routine control device maintenance 
exemption.
    (g) You must demonstrate continuous compliance with the operating 
limits in Table 2 to this subpart for visible emissions (VE) from tunnel 
kilns equipped with DLA, DIFF, or DLS/FF by monitoring VE at each kiln 
stack according to the requirements in paragraphs (g)(1) through (3) of 
this section.
    (1) Perform daily VE observations of each kiln stack according to 
the procedures of Method 22 of 40 CFR part 60, appendix A. You must 
conduct the Method 22 test while the affected source is operating under 
normal conditions. The duration of each Method 22 test must be at least 
15 minutes.
    (2) If VE are observed during any daily test conducted using Method 
22 of 40 CFR part 60, appendix A, you must promptly initiate and 
complete corrective actions according to your OM&M plan. If no VE are 
observed in 30 consecutive daily Method 22 tests for any kiln stack, you 
may decrease the frequency of Method 22 testing from daily to weekly for 
that kiln stack. If VE are observed during any weekly test, you must 
promptly initiate and complete corrective actions according to your OM&M 
plan, resume Method 22 testing of that kiln stack on a daily basis, and 
maintain that schedule until no VE are observed in 30 consecutive daily 
tests,

[[Page 783]]

at which time you may again decrease the frequency of Method 22 testing 
to a weekly basis.
    (3) If VE are observed during any test conducted using Method 22 of 
40 CFR part 60, appendix A, you must report these deviations by 
following the requirements in Sec. 63.8635.

Notification of Compliance Status before the close of business on the 
30th calendar day following the completion of the compliance 
demonstration.
    (f) If you request a routine control device maintenance exemption 
according to Sec. 63.8570(e), you must submit your request for the 
exemption no later than 30 days before the compliance date.

Sec. 63.8665  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, in 
Sec. 63.2, and in this section as follows:
    Air pollution control device (APCD) means any equipment that reduces 
the quantity of a pollutant that is emitted to the air.
    Bag leak detection system means an instrument that is capable of 
monitoring PM loadings in the exhaust of a fabric filter 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 effects to monitor relative PM 
loadings.
    Clay ceramics manufacturing facility means a plant site that 
manufactures pressed floor tile, pressed wall tile, other pressed tile, 
or sanitaryware (e.g., sinks and toilets). Clay ceramics manufacturing 
facilities typically process clay, shale, and various additives, form 
the processed materials into tile or sanitaryware shapes, and dry and 
fire the ceramic products. Glazes are applied to many tile and 
sanitaryware products.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limitation 
(including any operating limit) or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart for any affected source 
required to obtain such a permit; or
    (3) Fails to meet any emission limitation (including any operating 
limit) or work practice standard in this subpart during startup, 
shutdown, or malfunction, regardless of whether or not such failure is 
permitted by this subpart.
    Dry lime injection fabric filter (DIFF) means an APCD that includes 
continuous injection of hydrated lime or

[[Page 788]]

other sorbent into a duct or reaction chamber followed by a fabric 
filter.
    Dry lime scrubber/fabric filter (DLS/FF) means an APCD that includes 
continuous injection of humidified hydrated lime or other sorbent into a 
reaction chamber followed by a fabric filter. These systems typically 
include recirculation of some of the sorbent.
    Dry limestone adsorber (DLA) means an APCD that includes a limestone 
storage bin, a reaction chamber that is essentially a packed tower 
filled with limestone, and may or may not include a peeling drum that 
mechanically scrapes reacted limestone to regenerate the stone for 
reuse.
    Emission limitation means any emission limit or operating limit.
    Fabric filter means an APCD used to capture PM by filtering a gas 
stream through filter media; also known as a baghouse.
    Initial startup means:
    (1) For a new or reconstructed tunnel kiln controlled with a DLA, 
and for a tunnel kiln that would be considered reconstructed but for 
Sec. 63.8540(f)(1) or Sec. 63.8540(f)(2), the time at which the 
temperature in the kiln first reaches 260 [deg]C (500 [deg]F) and the 
kiln contains product; or
    (2) For a new or reconstructed tunnel kiln controlled with a DIFF, 
DLS/FF, or WS, the time at which the kiln first reaches a level of 
production that is equal to 75 percent of the kiln design capacity or 12 
months after the affected source begins firing clay ceramics, whichever 
is earlier.
    Particulate matter (PM) means, for purposes of this subpart, 
emissions of PM that serve as a measure of total particulate emissions, 
as measured by Method 5 (40 CFR part 60, appendix A), and as a surrogate 
for metal HAP contained in the particulates including, but not limited 
to, antimony, arsenic, beryllium, cadmium, chromium, cobalt, lead, 
manganese, mercury, nickel, and selenium.
    Period of natural gas curtailment or supply interruption means a 
period of time during which the supply of natural gas to an affected 
facility is halted for reasons beyond the control of the facility. An 
increase in the cost or unit price of natural gas does not constitute a 
period of natural gas curtailment or supply interruption.
    Plant site means all contiguous or adjoining property that is under 
common control, including properties that are separated only by a road 
or other public right-of-way. Common control includes properties that 
are owned, leased, or operated by the same entity, parent entity, 
subsidiary, or any combination thereof.
    Research and development kiln means any kiln whose purpose is to 
conduct research and development for new processes and products and is 
not engaged in the manufacture of products for commercial sale, except 
in a de minimis manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Startup means the setting in operation of an affected source and 
starting the production process.
    Tunnel kiln means any continuous kiln that is not a roller kiln that 
is used to fire clay ceramics.
    Tunnel kiln design capacity means the maximum amount of clay 
ceramics, in Mg (tons), that a kiln is designed to produce in one year 
divided by the number of hours in a year (8,760 hours). If a kiln is 
modified to increase the capacity, the design capacity is considered to 
be the capacity following modifications.
    Wet scrubber (WS) means an APCD that uses water, which may include 
caustic additives or other chemicals, as the sorbent. Wet scrubbers may 
use any of various design mechanisms to increase the contact between 
exhaust gases and the sorbent.
    Work practice standard means any design, equipment, work practice, 
operational standard, or combination thereof, that is promulgated 
pursuant to section 112(h) of the Clean Air Act.

Sec. 63.8680  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for existing and new asphalt processing and 
asphalt roofing manufacturing facilities. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with the 
emission limitations.



Sec. 63.8681  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate an asphalt 
processing facility or an asphalt roofing manufacturing facility, as 
defined in Sec. 63.8698, that is a major source of hazardous air 
pollutants (HAP) emissions, or is located at, or is part of a major 
source of HAP emissions.
    (b) After the applicable compliance date specified in Sec. 63.8683, 
blowing stills, asphalt storage tanks, saturators, wet loopers, and 
coaters subject to the provisions of this subpart that are also subject 
to 40 CFR part 60, subpart UU, are required to comply only with 
provisions of this subpart.
    (c) This subpart does not apply to any equipment that is subject to 
subpart CC of this part or to subpart K, Ka, or Kb of 40 CFR part 60.
    (d) This subpart does not apply to asphalt processing and asphalt 
roofing manufacturing equipment used for research and development, as 
defined in Sec. 63.8698.
    (e) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.07 megagrams (10 tons) or more per year or any combination of HAP 
at a rate of 22.68 megagrams (25 tons) or more per year.



Sec. 63.8682  What parts of my plant does this subpart cover?

    (2) Each asphalt roofing manufacturing line as defined in 
Sec. 63.8698.
    (i) If the asphalt roofing manufacturing line is collocated with an 
asphalt processing facility, the storage tanks that store asphalt flux 
intended for oxidation in the blowing stills and those tanks that 
receive asphalt directly from the on-site blowing stills are part of the 
asphalt processing facility. The remaining asphalt storage tanks are 
considered to be part of the asphalt roofing facility.
    (ii) If an asphalt storage tank is shared by two or more lines at an 
asphalt roofing manufacturing facility, the shared storage tank is 
considered part of the line to which the tank supplies the greatest 
amount of asphalt, on an annual basis.
    (iii) If a sealant or adhesive applicator is shared by two or more 
asphalt roofing manufacturing lines, the shared applicator is considered 
part of the line that provides the greatest throughput to the 
applicator, on an annual basis.
    (c) An affected source is a new affected source if you commenced 
construction of the affected source after November 21, 2001, and you met 
the applicability criteria at the time you commenced construction.
    (d) An affected source is reconstructed if you meet the criteria in 
the reconstruction definition in Sec. 63.2.
    (e) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.8683  When must I comply with this subpart?

Sec. 63.8698  What definitions apply to this subpart?

    Terms used in this subpart are defined in the Clean Air Act, in 40 
CFR 63.2, the General Provisions of this part, and in this section as 
follows:
    Adhesive applicator means the equipment used to apply adhesive to 
roofing shingles for producing laminated or dimensional roofing 
shingles.
    Asphalt flux means the organic residual material from distillation 
of crude oil that is generally used in asphalt roofing manufacturing and 
paving and non-paving asphalt products.
    Asphalt loading rack means the equipment at an asphalt processing 
facility used to transfer oxidized asphalt from a storage tank into a 
tank truck, rail car, or barge.
    Asphalt processing facility means any facility engaged in the 
preparation of asphalt flux at stand-alone asphalt processing 
facilities, petroleum refineries, and asphalt roofing facilities. 
Asphalt preparation, called ``blowing,'' is the oxidation of asphalt 
flux, achieved by bubbling air through the heated asphalt, to raise the 
softening point and to reduce penetration of the oxidized asphalt. An 
asphalt processing facility includes one or more asphalt flux blowing 
stills, asphalt flux storage tanks storing asphalt flux intended for 
processing in the blowing stills, oxidized asphalt storage tanks, and 
oxidized asphalt loading racks.
    Asphalt roofing manufacturing facility means a facility consisting 
of one or more asphalt roofing manufacturing lines.
    Asphalt roofing manufacturing line means the collection of equipment 
used to manufacture asphalt roofing products through a series of 
sequential process steps. The equipment that comprises an asphalt 
roofing manufacturing line varies depending on the type of substrate 
used (i.e., organic or inorganic) and the final product manufactured 
(e.g., roll roofing, laminated shingles). For example, an asphalt 
roofing manufacturing line that uses fiberglass mat as a substrate 
typically would not include a saturator/wet looper (or the saturator/wet 
looper could be bypassed if the line manufacturers multiple types of 
products). An asphalt roofing manufacturing line can include a saturator 
(including wet looper), coater, coating mixers, sealant applicators, 
adhesive applicators, and asphalt storage and process tanks. The number 
of asphalt roofing manufacturing lines at a particular facility is 
determined by the number of saturators (or coaters) operated in 
parallel. For example, an asphalt roofing manufacturing facility with 
two saturators (or coaters) operating in parallel would be considered to 
have two separate roofing manufacturing lines.
    Asphalt storage tank means any tank used to store asphalt flux, 
oxidized asphalt, and modified asphalt, at asphalt roofing manufacturing 
facilities, petroleum refineries, and asphalt processing facilities. 
Storage tanks containing cutback asphalts (asphalts diluted with 
solvents to reduce viscosity for low temperature applications) and 
emulsified asphalts (asphalts dispersed

[[Page 809]]

in water with an emulsifying agent) are not subject to this subpart.
    Blowing still means the equipment in which air is blown through 
asphalt flux to change the softening point and penetration rate of the 
asphalt flux, creating oxidized asphalt.
    Boiler means any enclosed combustion device that extracts useful 
energy in the form of steam and is not an incinerator.
    Coater means the equipment used to apply amended (filled or 
modified) asphalt to the top and bottom of the substrate (typically 
fiberglass mat) used to manufacture shingles and rolled roofing 
products.
    Coating mixer means the equipment used to mix coating asphalt and a 
mineral stabilizer, prior to applying the stabilized coating asphalt to 
the substrate.
    Combustion device means an individual unit of equipment such as a 
flare, incinerator, process heater, or boiler used for the combustion of 
organic hazardous air pollutant vapors.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart including, but not limited to, any emission limitation 
(including any operating limit), or work practice standard;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart, and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limitation (including any operating 
limit) or work practice standard in this subpart during startup, 
shutdown, or malfunction, regardless of whether or not such failure is 
permitted by this subpart.
    Emission limitation means any emission limit, opacity limit, 
operating limit, or visible emission limit.
    Group 1 asphalt loading rack means an asphalt loading rack loading 
asphalt with a maximum temperature of 260 [deg]C (500 [deg]F) or greater 
or with a maximum true vapor pressure of 10.4 kiloPascals (kPa) (1.5 
pounds per square inch absolute (psia)) or greater.
    Group 2 asphalt loading rack means an asphalt loading rack loading 
asphalt with a maximum temperature less than 260 [deg]C (500 [deg]F) or 
with a maximum true vapor pressure less than 10.4 kPa, 1.5 psia.
    Group 1 asphalt storage tank means an asphalt storage tank that 
meets both of the following two criteria:
    (1) Has a capacity of 177 cubic meters (47,000 gallons) of asphalt 
or greater; and
    (2) Stores asphalt at a maximum temperature of 260 [deg]C (500 
[deg]F) or greater, or has a maximum true vapor pressure of 10.4 kPa, 
(1.5, psia) or greater.
    Group 2 asphalt storage tank means any asphalt storage tank with a 
capacity of 1.93 megagrams (Mg) of asphalt or greater that is not a 
Group 1 asphalt storage tank.
    Incinerator means an enclosed combustion device that is used for 
destroying organic compounds. Auxiliary fuel may be used to heat waste 
gas to combustion temperatures. Any energy recovery section present is 
not physically formed into one manufactured or assembled unit with the 
combustion section; rather, the energy recovery section is a separate 
section following the combustion section and the two are joined by ducts 
or connections carrying flue gas.
    Maximum true vapor pressure means the equilibrium partial pressure 
exerted by the stored asphalt at its maximum storage temperature.
    Modified asphalt means asphalt that has been mixed with polymer 
modifiers.
    Oxidized asphalt means asphalt that has been prepared by passing air 
through liquid asphalt flux in a blowing still.
    Process heater means an enclosed combustion device that primarily 
transfers heat liberated by burning fuel directly to process streams or 
to heat transfer liquids other than water.
    Research and development equipment means any equipment whose primary 
purpose is to conduct research and development to develop new processes 
and products, where such equipment is operated under the close 
supervision of technically trained personnel and is not engaged in the 
manufacture of

[[Page 810]]

products for commercial sale in commerce, except in a de minimis manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.
    Saturator means the equipment in which substrate (predominantly 
organic felt) is filled with asphalt. Saturators are predominantly used 
for the manufacture of saturated felt products. The term saturator 
includes the saturator and wet looper.
    Sealant applicator means the equipment used to apply a sealant strip 
to a roofing product. The sealant strip is used to seal overlapping 
pieces of roofing product after they have been applied.
    Work practice standard means any design, equipment, work practice, 
or operational standard, or combination thereof, that is promulgated 
pursuant to section 112(h) of the Clean Air Act.

------------------------------------------------------------------------
a The operating limits specified in Table 2 and the requirements
  specified in Table 5 are applicable if you are monitoring control
  device operating parameters to demonstrate continuous compliance. If
  you use a CEMS or COMS to demonstrate compliance with the emission
  limits, you are not required to record control device operating
  parameters. However, you must maintain emissions below the value
  established during the initial performance test. Data from the CEMS
  and COMS must be reduced as specified in Sec.  63.9(g).
b Continuous parameter monitoring is not required if (1) the emissions
  are routed to a boiler or process heater with a with a design heat
  input capacity of 44 MW or greater; or (2) the emissions are
  introduced into the flame zone of a boiler or process heater.
c A 15-minute averaging period can be used as an alternative to the 3-
  hour averaging period for this parameter.
d As an alternative to monitoring the pressure drop across the control
  device, owners or operators using an ESP to achieve compliance with
  the emission limits specified in Table 1 of this subpart can monitor
  the voltage to the ESP. If this option is selected, the ESP voltage
  must be maintained at or above the operating limit established during
  the performance test.

Subpart MMMMM--National Emission Standards for Hazardous Air Pollutants: 
            Flexible Polyurethane Foam Fabrication Operations

    Source: 68 FR 18070, Apr. 14, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.8780  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) emitted from flexible polyurethane foam 
fabrication operations. This subpart also establishes requirements to 
demonstrate initial and continuous compliance with the emission 
standards.

[[Page 822]]



Sec. 63.8782  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a flexible 
polyurethane foam fabrication plant site that operates a flame 
lamination affected source, as defined at Sec. 63.8784(b)(2), and that 
is located at, or is part of a major emission source of hazardous air 
pollutants (HAP) or that operates a loop slitter affected source, as 
defined at Sec. 63.8784(b)(1), that meets the criteria in paragraphs 
(a)(1) and (2) of this section.
    (1) The loop slitter affected source uses one or more HAP-based 
adhesives at any time on or after April 14, 2003.
    (2) The loop slitter affected source is located at or is part of a 
major source of HAP.
    (b) A flexible polyurethane foam fabrication plant site is a plant 
site where pieces of flexible polyurethane foam are bonded together or 
to other substrates using HAP-based adhesives or flame lamination.
    (c) A major source of HAP is a plant site that emits or has the 
potential to emit any single HAP at a rate of 10 tons or more per year 
or any combination of HAP at a rate of 25 tons or more per year.
    (d) This subpart does not apply to the following processes in 
paragraphs (d)(1) and (2) of this section:
    (1) Processes that produce flexible polyurethane or rebond foam as 
defined in subpart III of this part.
    (2) A research and development facility, as defined in section 
112(c)(7) of the Clean Air Act (CAA).



Sec. 63.8784  What parts of my plant does this subpart cover?

    (a) This subpart applies to each existing, new, or reconstructed 
affected source at facilities engaged in flexible polyurethane foam 
fabrication.
    (b) The affected sources are defined in this section in paragraphs 
(b)(1) and (2) of this section.
    (1) The loop slitter adhesive use affected source is the collection 
of all loop slitters and associated adhesive application equipment used 
to apply HAP-based adhesives to bond foam to foam at a flexible 
polyurethane foam fabrication plant site.
    (2) The flame lamination affected source is the collection of all 
flame lamination lines associated with the flame lamination of foam to 
any substrate at a flexible polyurethane foam fabrication plant site.
    (c)(1) A new affected source is one that commences construction 
after August 8, 2001 and meets the applicability criteria of 
Sec. 63.8782 at the time construction commences.
    (2) If you add one or more flame lamination lines at a plant site

    (e) You must determine the percent reduction of HAP emissions during 
the performance test according to paragraphs (e)(1) through (3) of this 
section.
    (1) If you use chlorinated fire retardant foams, determine the 
percent reduction of HCl to represent HAP emissions from the source. If 
you do not use chlorinated fire retardant foams, determine the percent 
reduction of HCN to represent HAP emissions from the source.
    (2) Calculate the concentration of HAP at the control device inlet 
and at the control device outlet using the procedures in the specified 
test method.
    (3) Compare the calculated HAP concentration at the control device 
inlet to the calculated HAP concentration at the control device outlet 
to determine the percent reduction over the period of the performance 
test, using Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR14AP03.000


Where:

R=Efficiency of control device, percent.
Einlet,i=HAP concentration of control device inlet stream for 
    test run i, mg/dscm.
Eoutlet,i=HAP concentration of control device outlet stream 
    for test run i, mg/dscm.
n=Number of runs conducted for the performance test.

    (f) You must also meet the requirements in paragraphs (f)(1) and (2) 
of this section.
    (1) Conduct the performance tests using foams that are 
representative of foams typically used at your flame lamination affected 
source. If you use foams containing chlorinated fire retardants, you 
must conduct the performance tests using these foams.
    (2) Establish all applicable operating limits that correspond to the 
control system efficiency as described in Table 3 to this subpart.



Sec. 63.8802  What methods must I use to demonstrate compliance with the emission limitation for loop slitter adhesive use?

    (a) Determine the HAP content for each material used. To determine 
the HAP content for each material used in your foam fabrication 
operations, you must use one of the options in paragraphs (a)(1) through 
(3) of this section. If you use the option in paragraph (a)(3) of this 
section, you are subject to the provisions of paragraph (a)(4) of this 
section.
    (1) Method 311 (appendix A to 40 CFR part 63). You may use Method 
311 for determining the mass fraction of HAP. Use the procedures 
specified in paragraphs (a)(1)(i) and (ii) of this section when 
determining HAP content by Method 311.
    (i) Include in the HAP total each HAP that is measured to be present 
at

[[Page 825]]

0.1 percent by mass or more for Occupational Safety and Health 
Administration (OSHA)-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is measured to be 0.5 
percent of the material by mass, you do not need to include it in the 
HAP total. Express the mass fraction of each HAP you measure as a value 
truncated to four places after the decimal point (for example, 0.1234).
    (ii) Calculate the total HAP content in the test material by adding 
up the individual HAP contents and truncating the result to three places 
after the decimal point (for example, 0.123).
    (2) Alternative method. You may use an alternative test method for 
determining mass fraction of HAP if you obtain prior approval by the 
Administrator. You must follow the procedure in Sec. 63.7(f) to submit 
an alternative test method for approval.
    (3) Information from the supplier or manufacturer of the material. 
You may rely on information other than that generated by the test 
methods specified in paragraphs (a)(1) and (2) of this section to 
determine the mass fraction of HAP according to paragraphs (a)(3)(i) and 
(ii) of this section. This information may include, but is not limited 
to, a material safety data sheet (MSDS), a certified product data sheet 
(CPDS), or a manufacturer's hazardous air pollutant data sheet.
    (i) Include in the HAP total each HAP that is present at 0.1 percent 
by mass or more for OSHA-defined carcinogens as specified in 29 CFR 
1910.1200(d)(4) and at 1.0 percent by mass or more for other compounds. 
For example, if toluene (not an OSHA carcinogen) is 0.5 percent of the 
material by mass, you do not have to include it in the HAP total.
    (ii) If the HAP content is provided by the material supplier or 
manufacturer as a range, then you must use the upper limit of the range 
for determining compliance.
    (4) Verification of supplier or manufacturer information. Although 
you are not required to perform testing to verify the information 
obtained according to paragraph (a)(3) of this section, the 
Administrator may require a separate measurement of the total HAP 
content using the methods specified in paragraph (a)(1) or (2) of this 
section. If this measurement exceeds the total HAP content provided by 
the material supplier or manufacturer, then you must use the measured 
HAP content to determine compliance.
    (b) [Reserved]



Sec. 63.8806  How do I demonstrate initial compliance with the emission limitations?

    (a) You must demonstrate initial compliance with each emission limit 
that applies to you according to Table 4 to this subpart.
    (b) You must establish each site-specific operating limit in Table 2 
to this subpart that applies to you according to the requirements in 
Sec. 63.8800 and Table 3 to this subpart.
    (c) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.8816(e) through (h).

source, you must meet the requirements in paragraphs (a)(1) and (2) of 
this section.
    (1) Maintain a list of each adhesive and the manufacturer or 
supplier of each.
    (2) Maintain a record of EPA Method 311 (appendix A to 40 CFR part 
63), approved alternative method, or other reasonable means of HAP 
content determinations indicating the mass percent of each HAP for each 
adhesive.
    (b) If you own or operate a new or reconstructed flame lamination 
affected source, you must meet the requirements in paragraphs (b)(1) 
through (3) of this section if you use a scrubber, or paragraph (b)(4) 
of this section if you use any other control device.
    (1) Keep records of the daily average scrubber inlet liquid flow 
rate.
    (2) Keep records of the daily average scrubber effluent pH.

[[Page 826]]

    (3) If you use a venturi scrubber, keep records of daily average 
pressure drop across the venturi.
    (4) Keep records of operating parameter values for each operating 
parameter that applies to you.
    (c) If you own or operate a new or reconstructed flame lamination 
affected source, you must meet the requirements in paragraphs (c)(1) 
through (4) of this section.
    (1) Except for periods of monitoring malfunctions, associated 
repairs, and required quality assurance or control activities 
(including, as applicable, calibration checks and required zero and span 
adjustments), you must monitor continuously (or collect data at all 
required intervals) at all times that the affected source is operating. 
This includes periods of startup, shutdown, and malfunction when the 
affected source is operating. A monitoring malfunction includes, but is 
not limited to, any sudden, infrequent, not reasonably preventable 
failure of the monitoring device to provide valid data. Monitoring 
failures that are caused by poor maintenance or careless operation are 
not malfunctions.
    (2) In data average calculations and calculations used to report 
emission or operating levels, you may not use data recorded during 
monitoring malfunctions, associated repairs, or recorded during required 
quality assurance or control activities. Nor may such data be used in 
fulfilling any applicable minimum data availability requirement. You 
must use all the data collected during all other periods in assessing 
the operation of the control device and associated control system.
    (3) You must conduct a performance evaluation of each CMS in 
accordance with your site-specific monitoring plan.
    (4) You must operate and maintain the CMS in continuous operation 
according to the site-specific monitoring plan.



Sec. 63.8812  How do I demonstrate continuous compliance with the emission limitations?

limit and operating limit in Tables 1 and 2 to this subpart that applies 
to you according to the methods specified in Table 5 to this subpart.
    (b) You must report each instance in which you did not meet each 
emission limit and each operating limit in Tables 1 and 2 to this 
subpart that apply to you. For new or reconstructed flame lamination 
affected sources, this includes periods of startup, shutdown, and 
malfunction. These instances are deviations from the operating limits in 
this subpart. These deviations must be reported according to the 
requirements in Sec. 63.8818.
    (c) For each new or reconstructed flame lamination affected source, 
you must operate in accordance with the startup, shutdown, and 
malfunction plan during periods of startup, shutdown, and malfunction.
    (d) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur at a new or reconstructed flame lamination affected source 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 startup, shutdown, and malfunction plan. The 
Administrator will determine whether deviations that occur at a new or 
reconstructed flame lamination affected source during a period of 
startup, shutdown, or malfunction are violations, according to the 
provisions in Sec. 63.6(e).
    (e) You also must meet the following requirements if you are 
complying with the adhesive use ban for loop slitter adhesive use 
described in Sec. 63.8790(a).
    (1) If, after you submit the Notification of Compliance Status, you 
use an adhesive for which you have not previously verified percent HAP 
mass using the methods in Sec. 63.8802, you must verify that each 
adhesive used in the affected source meets the emission limit, using any 
of the methods in Sec. 63.8802.
    (2) You must update the list of all the adhesives used at the 
affected source.
    (3) With the compliance report for the reporting period during which 
you used the new adhesive, you must submit the updated list of all 
adhesives and a statement certifying that, as purchased, each adhesive 
used at the

[[Page 827]]

affected source during the reporting period met the emission limit in 
Table 1 to this subpart.

this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limitation (including 
any operating limit); or
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limitation (including any operating 
limit) in this subpart during startup, shutdown, or malfunction, 
regardless of whether or not such failure is permitted by this subpart.
    Emission limitation means any emission limit or operating limit.
    Flame lamination means the process of bonding flexible foam to one 
or more layers of material by heating the foam surface with an open 
flame.
    Flame lamination line means the flame laminator and associated 
rollers.
    HAP-based adhesive means an adhesive containing 5 percent (by 
weight) or more of HAP, according to EPA Method 311 (appendix A to 40 
CFR part 63) or another approved alternative.
    Loop slitter means a machine used to create thin sheets of foam from 
the large blocks of foam or ``buns'' created at a slabstock flexible 
polyurethane foam production plant.
    Research and development process means a laboratory or pilot plant 
operation whose primary purpose is to conduct research and development 
into new processes and products where the operations are under the close 
supervision of technically trained personnel, and which is not engaged 
in the manufacture of products for commercial sale, except in a de 
minimis manner.
    Responsible official means responsible official as defined in 40 CFR 
70.2.

Subpart NNNNN--National Emission Standards for Hazardous Air Pollutants: 
                      Hydrochloric Acid Production

    Source: 68 FR 19090, Apr. 17, 2003, unless otherwise noted.

                        What This Subpart Covers



63.8980  What is the purpose of this subpart?

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



Sec. 63.8985  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate an HCl 
production facility that produces a liquid HCl product at a 
concentration of 30 weight percent or greater during its normal 
operations and is located at, or is part of, a major source of HAP. This 
does not include HCl production facilities that only produce 
occasionally liquid HCl product at a concentration of 30 weight percent 
or greater.
    (1) An HCl production facility is the collection of unit operations 
and equipment associated with the production of liquid HCl product. The 
HCl production facility begins at the point where a gaseous stream 
containing HCl enters the HCl production unit. The HCl production 
facility includes all HCl storage tanks that contain liquid HCl product 
that is produced in the HCl production unit, with the exceptions noted 
in paragraph (a)(2) of this section. The HCl production facility also 
includes all HCl transfer operations that load HCl product produced in 
the HCl production unit into a tank truck, rail car, ship, or barge, 
along with the piping and other equipment in HCl service used to 
transfer liquid HCl product from the HCl production unit to the HCl 
storage tanks and/or HCl transfer operations. The HCl production 
facility ends at the point that the liquid HCl

[[Page 837]]

product produced in the HCl production unit is loaded into a tank truck, 
rail car, ship, or barge, at the point the HCl product enters another 
process on the plant site, or at the point the HCl product leaves the 
plant site via pipeline.
    (2) Storage tanks that are dedicated feedstock tanks for another 
process and storage tanks that store HCl dedicated for use in wastewater 
treatment are not considered part of an HCl production facility.
    (3) A major source of HAP emissions is any stationary source or 
group of stationary sources within a contiguous area under common 
control that emits or has the potential to emit any single HAP at a rate 
of 9.07 megagrams (10 tons) or more per year or any combination of HAP 
at a rate of 22.68 megagrams (25 tons) or more per year.
    (b) An HCl production facility is not subject to this subpart if it 
is also subject to NESHAP under one of the subparts listed in paragraphs 
(b)(1) through (5) of this section.
    (1) 40 CFR part 63, subpart S, National Emission Standards for 
Hazardous Air Pollutants from the Pulp and Paper Industry.
    (2) 40 CFR part 63, subpart CCC, National Emission Standards for 
Hazardous Air Pollutants for Steel Pickling--HCl Process Facilities and 
Hydrochloric Acid Regeneration Plants.
    (3) 40 CFR part 63, subpart MMM, National Emission Standards for 
Hazardous Air Pollutants for Pesticide Active Ingredient Production.
    (4) 40 CFR part 63, subpart EEE, National Emission Standards for 
Hazardous Air Pollutants for Hazardous Waste Combustors.
    (5) 40 CFR part 63, subpart GGG, National Emission Standards for 
Pharmaceuticals Production.
    (c) An HCl production facility is not subject to this subpart if it 
is located following the incineration of chlorinated waste gas streams, 
waste liquids, or solid wastes, and the emissions from the HCl 
production facility are subject to one of the requirements listed in 
paragraphs (c)(1) through (3) of this section.
    (1) Section 63.113(c), subpart G, National Emission Standards for 
Organic Hazardous Air Pollutants from the Synthetic Organic Chemical 
Manufacturing Industry for Process Vents, Storage Vessels, Transfer 
Operations, and Wastewater.
    (2) Section 264.343(b), Standards for Owners and Operators of 
Hazardous Waste Treatment, Storage, and Disposal Facilities (subpart O, 
Incinerators).
    (3) Section 266.107, subpart H, Burning of Hazardous Waste in 
Boilers and Industrial Furnaces.
    (d) An HCl production facility is not subject to this subpart if it 
produces HCl through the direct synthesis of hydrogen and chlorine and 
is part of a chlor-alkali facility.
    (e) An HCl production facility is not subject to this subpart if it 
is a research and development facility.
    (f) An HCl production facility is not subject to this subpart if all 
of the gaseous streams containing HCl and chlorine (Cl2) from 
HCl process vents, HCl storage tanks, and HCl transfer operations are 
recycled or routed to another process prior to being discharged to the 
atmosphere.



Sec. 63.8990  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at an HCl production facility.
    (b) The affected source is the group of one or more HCl production 
facilities at a plant site that are subject to this subpart, and all 
associated wastewater operations, which contain the collection of 
emission streams listed in paragraphs (b)(1) through (5) of this 
section.
    (1) Each emission stream from an HCl process vent.
    (2) Each emission stream from an HCl storage tank.
    (3) Each emission stream from an HCl transfer operation.

Subpart PPPPP--National Emission Standards for Hazardous Air Pollutants 
                     for Engine Test Cells/Standards

    Source: 68 FR 28785, May 27, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.9280  What is the purpose of subpart PPPPP?

    This subpart PPPPP establishes national emission standards for 
hazardous air pollutants (NESHAP) for engine test cells/stands located 
at major sources of hazardous air pollutants (HAP) emissions. This 
subpart also establishes requirements to demonstrate initial and 
continuous compliance with the emission limitations contained in this 
NESHAP.



Sec. 63.9285  Am I subject to this subpart?

    You are subject to this subpart if you own or operate an engine test 
cell/stand that is located at a major source of HAP emissions.
    (a) An engine test cell/stand is any apparatus used for testing 
uninstalled stationary or uninstalled mobile (motive) engines.
    (b) An uninstalled engine is an engine that is not installed in, or 
an integrated part of, the final product.
    (c) A major source of HAP emissions is a plant site that emits or 
has the potential to emit any single HAP at a rate of 10 tons (9.07 
megagrams) or more per year or any combination of HAP at a rate of 25 
tons (22.68 megagrams) or more per year.



Sec. 63.9290  What parts of my plant does this subpart cover?

    This subpart applies to each new, reconstructed, or existing 
affected source.
    (a) Affected source. An affected source is the collection of all 
equipment and activities associated with engine test cells/stands used 
for testing uninstalled stationary or uninstalled mobile (motive) 
engines located at a major source of HAP emissions.
    (1) Existing affected source. An affected source is existing if you 
commenced construction or reconstruction of the affected source on or 
before May 14, 2002. A change in ownership of an existing affected 
source does not make

[[Page 856]]

that affected source a new or reconstructed affected source.
    (2) New affected source. An affected source is new if you commenced 
construction of the affected source after May 14, 2002.
    (3) Reconstructed affected source. An affected source is 
reconstructed if you meet the definition of reconstruction in Sec. 63.2 
of subpart A of this part and reconstruction is commenced after May 14, 
2002. Changes made to an existing affected source primarily for the 
purpose of complying with revisions to engine testing requirements under 
40 CFR parts 80, 86, 89, 90, 91, or 92 are not considered a modification 
or reconstruction. In addition, passive measurement and control 
instrumentation and electronics are not included as part of any affected 
source reconstruction evaluation.
    (b) Existing affected sources do not have to meet the requirements 
of this subpart and of subpart A of this part.
    (c) Any portion of a new or reconstructed affected source located at 
a major source that is used exclusively for testing internal combustion 
engines with rated power of less than 25 horsepower (hp) (19 
kilowatts(kW)) does not have to meet the requirements of this subpart 
and of subpart A of this part except for the initial notification 
requirements of Sec. 63.9345(b).
    (d) Any portion of a new or reconstructed affected source located at 
a major source that meets any of the criteria specified in paragraphs 
(d)(1) through (4) of this section does not have to meet the 
requirements of this subpart and of subpart A of this part.
    (1) Any portion of the affected source used exclusively for testing 
combustion turbine engines.
    (2) Any portion of the affected source used exclusively for testing 
rocket engines.
    (3) Any portion of the affected source used in research and teaching 
activities at facilities that are not engaged in the development of 
engines or engine test services for commercial purposes.
    (4) Any portion of the affected source operated to test or evaluate 
fuels (such as knock engines), transmissions, or electronics.



Sec. 63.9295  When do I have to comply with this subpart?

    (a) Affected sources.
    (1) If you start up your new or reconstructed affected source before 
May 27, 2003, you must comply with the emission limitations in this 
subpart no later than May 27, 2003.
    (2) If you start up your new or reconstructed affected source on or 
after May 27, 2003, you must comply with the emission limitations in 
this subpart upon startup.
    (b) Area sources that become major sources. If your new or 
reconstructed affected source is located at an area source that 
increases its emissions or its potential to emit such that it becomes a 
major source of HAP, your new or reconstructed affected source must be 
in compliance with this subpart when the area source becomes a major 
source.
    (c) You must meet the notification requirements in Sec. 63.9345 and 
in 40 CFR part 63, subpart A.

                          Emission Limitations



Sec. 63.9300  What emission limitations must I meet?

    For each new or reconstructed affected source that is used in whole 
or in part for testing internal combustion engines with rated power of 
25 hp (19 kW) or more and that is located at a major source, you must 
comply with the emission limitations in Table 1 to this subpart. (Tables 
are found at the end of this subpart.)



Sec. 63.9301  What are my options for meeting the emission limits?

    You may use either a continuous parameter monitoring system (CPMS) 
or a continuous emission monitoring system (CEMS) to demonstrate 
compliance with the emission limitations. Continuous monitoring systems 
must meet the requirements in Sec. 63.9306 (CPMS) and Sec. 63.9307 
(CEMS).



Sec. 63.9302  What operating limits must I meet?

    (a) For any new or reconstructed affected source on which you use 
add-on controls, you must meet the operating limits specified in Table 2 
to this subpart. These operating limits must be

[[Page 857]]

established during the performance test according to the requirements in 
Sec. 63.9324. You must meet the operating limits at all times after you 
establish them.
    (b) If you use an add-on control device other than those listed in 
Table 2 to this subpart, or wish to monitor an alternative parameter and 
comply with a different operating limit, you must apply to the 
Administrator for approval of alternative monitoring under Sec. 63.8(f).

                     General Compliane Requirements



Sec. 63.9305  What are my general requirements for complying with this subpart?

    (a) You must be in compliance with the emission limitation that 
applies to you at all times, except during periods of startup, shutdown, 
or malfunction (SSM) of your control device or associated monitoring 
equipment.
    (b) If you must comply with the emission limitation, you must 
operate and maintain your engine test cell/stand, air pollution control 
equipment, and monitoring equipment in a manner consistent with good air 
pollution control practices for minimizing emissions at all times.
    (c) You must develop and implement a written SSM plan (SSMP) for 
emission control devices and associated monitoring equipment according 
to the provisions in Sec. 63.6(e)(3). The plan will apply only to 
emission control devices, and not to engine test cells/stands.



Sec. 63.9306  What are my continuous parameter monitoring system (CPMS) installation, operation, and maintenance requirements?

    (a) General. You must install, operate, and maintain each CPMS 
specified in paragraphs (c) and (d) of this section according to 
paragraphs (a)(1) through (7) of this section. You must install, 
operate, and maintain each CPMS specified in paragraph (b) of this 
section according to paragraphs (a)(3) through (5) of this section.
    (1) The CPMS must complete a minimum of one cycle of operation for 
each successive 15-minute period. You must have a minimum of four 
equally spaced successive cycles of CPMS operation in 1 hour.
    (2) You must determine the average of all recorded readings for each 
successive 3-hour period of the emission capture system and add-on 
control device operation.
    (3) You must record the results of each inspection, calibration, and 
validation check of the CPMS.
    (4) You must maintain the CPMS at all times and have available 
necessary parts for routine repairs of the monitoring equipment.
    (5) You must operate the CPMS and collect emission capture system 
and add-on control device parameter data at all times that an engine 
test cell/stand is operating, except during monitoring malfunctions, 
associated repairs, and required quality assurance or control activities 
(including, if applicable, calibration checks and required zero and span 
adjustments).
    (6) You must not use emission capture system or add-on control 
device parameter data recorded during monitoring malfunctions, 
associated repairs, out-of-control periods, or required quality 
assurance or control activities when calculating data averages. You must 
use all the data collected during all other periods in calculating the 
data averages for determining compliance with the emission capture 
system and add-on control device operating limits.
    (7) A monitoring malfunction is any sudden, infrequent, not 
reasonably preventable failure of the CPMS to provide valid data. 
Monitoring failures that are caused in part by poor maintenance or 
careless operation are not malfunctions. Any period for which the 
monitoring system is out-of-control and data are not available for 
required calculations is a deviation from the monitoring requirements.
    (b) Capture system bypass line. You must meet the requirements of 
paragraphs (b)(1) and (2) of this section for each emission capture 
system that contains bypass lines that could divert emissions away from 
the add-on control device to the atmosphere.
    (1) You must monitor or secure the valve or closure mechanism 
controlling the bypass line in a nondiverting position in such a way 
that the valve or closure mechanism cannot be opened without creating a 
record that the

[[Page 858]]

valve was opened. The method used to monitor or secure the valve or 
closure mechanism must meet one of the requirements specified in 
paragraphs (b)(1)(i) through (iv) of this section.
    (i) Flow control position indicator. Install, calibrate, maintain, 
and operate according to the manufacturer's specifications a flow 
control position indicator that takes a reading at least once every 15 
minutes and provides a record indicating whether the emissions are 
directed to the add-on control device or diverted from the add-on 
control device. The time of occurrence and flow control position must be 
recorded, as well as every time the flow direction is changed. The flow 
control position indicator must be installed at the entrance to any 
bypass line that could divert the emissions away from the add-on control 
device to the atmosphere.
    (ii) Car-seal or lock-and-key valve closures. Secure any bypass line 
valve in the closed position with a car-seal or a lock-and-key type 
configuration. You must visually inspect the seal or closure mechanism 
at least once every month to ensure that the valve is maintained in the 
closed position, and the emissions are not diverted away from the add-on 
control device to the atmosphere.
    (iii) Valve closure monitoring. Ensure that any bypass line valve is 
in the closed (nondiverting) position through monitoring of valve 
position at least once every 15 minutes. You must inspect the monitoring 
system at least once every month to verify that the monitor will 
indicate valve position.
    (iv) Automatic shutdown system. Use an automatic shutdown system in 
which the engine testing operation is stopped when flow is diverted by 
the bypass line away from the add-on control device to the atmosphere 
when an engine test cell/stand is operating. You must inspect the 
automatic shutdown system at least once every month to verify that it 
will detect diversions of flow and shut down the engine test cell/stand 
in operation.
    (2) If any bypass line is opened, you must include a description of 
why the bypass line was opened and the length of time it remained open 
in the semiannual compliance reports required in Sec. 63.9350.
    (c) Thermal oxidizers and catalytic oxidizers. If you are using a 
thermal oxidizer or catalytic oxidizer as an add-on control device, you 
must comply with the requirements in paragraphs (c)(1) through (3) of 
this section.
    (1) For a thermal oxidizer, install a gas temperature monitor in the 
firebox of the thermal oxidizer or in the duct immediately downstream of 
the firebox before any substantial heat exchange occurs.
    (2) For a catalytic oxidizer, you must install a gas temperature 
monitor in the gas stream immediately before the catalyst bed, and if 
you established operating limits according to Sec. 63.9324(b)(1) and 
(2), also install a gas temperature monitor in the gas stream 
immediately after the catalyst bed.
    (i) If you establish operating limits according to 
Sec. 63.9324(b)(1) and (2), then you must install the gas temperature 
monitors both upstream and downstream of the catalyst bed. The 
temperature monitors must be in the gas stream immediately before and 
after the catalyst bed to measure the temperature difference across the 
bed.
    (ii) If you establish operating limits according to 
Sec. 63.9324(b)(3) and (4), then you must install a gas temperature 
monitor upstream of the catalyst bed. The temperature monitor must be in 
the gas stream immediately before the catalyst bed to measure the 
temperature.
    (3) For all thermal oxidizers and catalytic oxidizers, you must meet 
the requirements in paragraphs (a) and (c)(3)(i) through (vii) of this 
section for each gas temperature monitoring device.
    (i) Locate the temperature sensor in a position that provides a 
representative temperature.
    (ii) Use a temperature sensor with a measurement sensitivity of 4 
degrees Fahrenheit or 0.75 percent of the temperature value, whichever 
is larger.
    (iii) Shield the temperature sensor system from electromagnetic 
interference and chemical contaminants.
    (iv) If a gas temperature chart recorder is used, it must have a 
measurement sensitivity in the minor division of at least 20 degrees 
Fahrenheit.
    (v) Perform an electronic calibration at least semiannually 
according to the

[[Page 859]]

procedures in the manufacturer's owner's manual. Following the 
electronic calibration, you must conduct a temperature sensor validation 
check in which a second or redundant temperature sensor placed near the 
process temperature sensor must yield a reading within 30 degrees 
Fahrenheit of the process temperature sensor reading.
    (vi) Conduct calibration and validation checks anytime the sensor 
exceeds the manufacturer's specified maximum operating temperature range 
or install a new temperature sensor.
    (vii) At least monthly, inspect components for integrity and 
electrical connections for continuity, oxidation, and galvanic 
corrosion.
    (d) Emission capture systems. The capture system monitoring system 
must comply with the applicable requirements in paragraphs (d)(1) and 
(2) of this section.
    (1) For each flow measurement device, you must meet the requirements 
in paragraphs (a) and (d)(1)(i) through (iv) of this section.
    (i) Locate a flow sensor in a position that provides a 
representative flow measurement in the duct from each capture device in 
the emission capture system to the add-on control device.
    (ii) Reduce swirling flow or abnormal velocity distributions due to 
upstream and downstream disturbances.
    (iii) Conduct a flow sensor calibration check at least semiannually.
    (iv) At least monthly, inspect components for integrity, electrical 
connections for continuity, and mechanical connections for leakage.
    (2) For each pressure drop measurement device, you must comply with 
the requirements in paragraphs (a) and (d)(2)(i) through (vi) of this 
section.
    (i) Locate the pressure sensor(s) in or as close to a position that 
provides a representative measurement of the pressure drop across each 
opening you are monitoring.
    (ii) Minimize or eliminate pulsating pressure, vibration, and 
internal and external corrosion.
    (iii) Check pressure tap pluggage daily.
    (iv) Using an inclined manometer with a measurement sensitivity of 
0.0002 inch water, check gauge calibration quarterly and transducer 
calibration monthly.
    (v) Conduct calibration checks any time the sensor exceeds the 
manufacturer's specified maximum operating pressure range or install a 
new pressure sensor.
    (vi) At least monthly, inspect components for integrity, electrical 
connections for continuity, and mechanical connections for leakage.



Sec. 63.9307  What are my continuous emissions monitoring system installation, operation, and maintenance requirements?

    (a) You must install, operate, and maintain each CEMS to monitor 
carbon monoxide (CO) or total hydrocarbons (THC) and oxygen 
(O2) at the outlet of the exhaust system of the engine test 
cell/stand or at the outlet of the emission control device.
    (b) To comply with the CO or THC percent reduction emission 
limitation, you may install, operate, and maintain a CEMS to monitor CO 
or THC and O2 at both the inlet and the outlet of the 
emission control device.
    (c) To comply with either emission limitations, the CEMS must be 
installed and operated according to the requirements described in 
paragraphs (c)(1) through (4) of this section.

monitoring equipment.
    (2) Continued Operation. You must operate your CEMS according to 
paragraphs (d)(2)(i) and (ii) of this section.
    (i) You must conduct all monitoring in continuous operation at all 
times that the engine test cell/stand is operating, except for, as 
applicable, monitoring malfunctions, associated repairs, and required 
quality assurance or control activities (including, as applicable, 
calibration drift checks and required zero and high-level adjustments). 
Quality assurance or control activities must be performed according to 
procedure 1 of 40 CFR part 60, appendix F.
    (ii) Data recorded during monitoring malfunctions, associated 
repairs, out-of-control periods, and required quality assurance or 
control activities must not be used for purposes of calculating data 
averages. You must use all of the data collected from all other periods 
in assessing compliance. A monitoring malfunction is any sudden, 
infrequent, not reasonably preventable failure of the monitoring 
equipment to provide valid data. Monitoring failures that are caused in 
part by poor maintenance or careless operation are not malfunctions. Any 
period for which the monitoring system is out-of-control and data are 
not available for required calculations constitutes a deviation from the 
monitoring requirements.

               Testing and Initial Compliance Requirements



Sec. 63.9310  By what date must I conduct the initial compliance demonstrations?

    You must conduct the initial compliance demonstrations that apply to 
you in Table 3 to this subpart within 180 calendar days after the 
compliance date that is specified for your new or reconstructed affected 
source in Sec. 63.9295 and according to the provisions in 
Sec. 63.7(a)(2).



Sec. 63.9320  What procedures must I use?

    (a) You must conduct each initial compliance demonstration that 
applies to you in Table 3 to this subpart.
    (b) You must conduct an initial performance evaluation of each 
capture and control system according to Secs. 63.9321, 63.9322, 63.9323 
and 63.9324, and each CEMS according to the requirements in 40 CFR 63.8 
and according to the applicable Performance Specification of 40 CFR part 
60, appendix B (PS-3 or PS-4A).
    (c) The initial demonstration of compliance with the carbon monoxide 
(CO) or total hydrocarbon (THC) concentration limitation consists of the 
first 4-hour rolling average CO or THC concentration recorded after 
completion of the CEMS performance evaluation. You must correct the CO 
or THC concentration at the outlet of the engine test cell/stand or the 
emission control device to a dry basis and to 15 percent O2 
content according to Equation 1 of this section:
[GRAPHIC] [TIFF OMITTED] TR27MY03.002

Where:
Cc = concentration of CO or THC, corrected to 15 percent 
oxygen, ppmvd
Cunc = total uncorrected concentration of CO or THC, ppmvd

[[Page 861]]

%O2d = concentration of oxygen measured in gas stream, dry 
basis, percent by volume.
    (d) The initial demonstration of compliance with the CO or THC 
percent reduction emission limitation consists of the first 4-hour 
rolling average percent reduction in CO or THC recorded after completion 
of the performance evaluation of the capture/control system and/or CEMS. 
You must complete the actions described in paragraphs (d)(1) through (2) 
of this section.
    (1) Correct the CO or THC concentrations at the inlet and outlet of 
the emission control device to a dry basis and to 15 percent 
O2 content using Equation 1 of this section.
    (2) Calculate the percent reduction in CO or THC using Equation 2 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR27MY03.003

Where:

R = percent reduction in CO or THC
Ci = corrected CO or THC concentration at inlet of the 
emission control device
Co = corrected CO or THC concentration at the outlet of the 
emission control device.



Sec. 63.9321  What are the general requirements for performance tests?

    (a) You must conduct each performance test required by Sec. 63.9310 
according to the requirements in Sec. 63.7(e)(1) and under the 
conditions in this section unless you obtain a waiver of the performance 
test according to the provisions in Sec. 63.7(h).
    (1) Representative engine testing conditions. You must conduct the 
performance test under representative operating conditions for the test 
cell/stand. Operations during periods of SSM, and during periods of 
nonoperation do not constitute representative conditions. You must 
record the process information that is necessary to document operating 
conditions during the test and explain why the conditions represent 
normal operation.
    (2) Representative emission capture system and add-on control device 
operating conditions. You must conduct the performance test when the 
emission capture system and add-on control device are operating at a 
representative flow rate, and the add-on control device is operating at 
a representative inlet concentration. You must record information that 
is necessary to document emission capture system and add-on control 
device operating conditions during the test and explain why the 
conditions represent normal operation.
    (b) You must conduct each performance test of an emission capture 
system according to the requirements in Sec. 63.9322. You must conduct 
each performance test of an add-on control device according to the 
requirements in Sec. 63.9323.



Sec. 63.9322  How do I determine the emission capture system efficiency?

    You must use the procedures and test methods in this section to 
determine capture efficiency as part of the performance test required by 
Sec. 63.9310.
    (a) Assuming 100 percent capture efficiency. You may assume the 
capture system efficiency is 100 percent if both conditions in 
paragraphs (a)(1) and (2) of this section are met:
    (1) The capture system meets the criteria in Method 204 of appendix 
M to 40 CFR part 51 for a potential to emit (PTE) and directs all the 
exhaust gases from the enclosure to an add-on control device.
    (2) All engine test operations creating exhaust gases for which the 
test is applicable are conducted within the capture system.
    (b) Measuring capture efficiency. If the capture system does not 
meet the criteria in paragraphs (a)(1) and (2) of this section, then you 
must use one of the two protocols described in paragraphs (c) and (d) of 
this section to measure capture efficiency. The capture efficiency 
measurements use total volatile hydrocarbon (TVH) capture efficiency as 
a surrogate for organic HAP capture efficiency. For the protocol in 
paragraph (c) of this section, the capture efficiency measurement must 
consist of three test runs. Each test run must be at least 3 hours in 
duration or the length of a production run, whichever is longer, up to 8 
hours. For the purposes of this test, a production run means the time 
required for a single

[[Page 862]]

engine test to go from the beginning to the end.
    (c) Gas-to-gas protocol using a temporary total enclosure or a 
building enclosure. The gas-to-gas protocol compares the mass of TVH 
emissions captured by the emission capture system to the mass of TVH 
emissions not captured. Use a temporary total enclosure or a building 
enclosure and the procedures in paragraphs (c)(1) through (5) of this 
section to measure emission capture system efficiency using the gas-to-
gas protocol.
    (1) Either use a building enclosure or construct an enclosure around 
the engine test cell/stand and all areas where emissions from the engine 
testing subsequently occur. The enclosure must meet the applicable 
definition of a temporary total enclosure or building enclosure in 
Method 204 of appendix M to 40 CFR part 51.
    (2) Use Method 204B or 204C of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions captured by the emission 
capture system during each capture efficiency test run as measured at 
the inlet to the add-on control device. To make the measurement, 
substitute TVH for each occurrence of the term VOC in the methods.
    (i) The sampling points for the Method 204B or 204C of appendix M to 
40 CFR part 51 measurement must be upstream from the add-on control 
device and must represent total emissions routed from the capture system 
and entering the add-on control device.
    (ii) If multiple emission streams from the capture system enter the 
add-on control device without a single common duct, then the emissions 
entering the add-on control device must be simultaneously measured in 
each duct, and the total emissions entering the add-on control device 
must be determined.
    (3) Use Method 204D or 204E of appendix M to 40 CFR part 51 to 
measure the total mass, kg, of TVH emissions that are not captured by 
the emission capture system; they are measured as they exit the 
temporary total enclosure or building enclosure during each capture 
efficiency test run. To make the measurement, substitute TVH for each 
occurrence of the term VOC in the methods.
    (i) Use Method 204D of appendix M to 40 CFR part 51 if the enclosure 
is a temporary total enclosure.
    (ii) Use Method 204E of appendix M to 40 CFR part 51 if the 
enclosure is a building enclosure. During the capture efficiency 
measurement, all organic compound emitting operations inside the 
building enclosure, other than the engine test cell/stand operation for 
which capture efficiency is being determined, must be shut down, but all 
fans and blowers must be operating normally.
    (4) For each capture efficiency test run, determine the percent 
capture efficiency of the emission capture system using Equation 1 of 
this section:
[GRAPHIC] [TIFF OMITTED] TR27MY03.004

Where:
CE = capture efficiency of the emission capture system vented to the 
add-on control device, percent
TVH captured = total mass of TVH captured by the emission 
capture system as measured at the inlet to the add-on control device 
during the emission capture efficiency test run, kg, determined 
according to paragraph (c)(2) of this section
TVH uncaptured = total mass of TVH that is not captured by 
the emission capture system and that exits from the temporary total 
enclosure or building enclosure during the capture efficiency test run, 
kg, determined according to paragraph (c)(3) of this section.

    (5) Determine the capture efficiency the emission capture system as 
the average of the capture efficiencies measured in the three test runs.

[[Page 863]]

    (d) Alternative capture efficiency protocol. As an alternative to 
the procedure specified in paragraph (c) of this section, you may 
determine capture efficiency using any other capture efficiency protocol 
and test methods that satisfy the criteria of either the data quality 
objective or lower control limit approach as described in appendix A to 
subpart KK of this part.



Sec. 63.9323  How do I determine the add-on control device emission destruction or removal efficiency?

    You must use the procedures and test methods in this section to 
determine the add-on control device emission destruction or removal 
efficiency as part of the performance test required by Sec. 63.9310. You 
must conduct three test runs as specified in Sec. 63.7(e)(3), and each 
test run must last at least 1 hour.
    (a) For all types of add-on control devices, use the test methods 
specified in paragraphs (a)(1) through (5) of this section.
    (1) Use Method 1 or 1A of appendix A to 40 CFR part 60, as 
appropriate, to select sampling sites and velocity traverse points.
    (2) Use Method 2, 2A, 2C, 2D, 2F, or 2G of appendix A to 40 CFR part 
60, as appropriate, to measure gas volumetric flow rate.
    (3) Use Method 3, 3A, or 3B of appendix A to 40 CFR part 60, as 
appropriate, for gas analysis to determine dry molecular weight. The 
ANSI/ASME PTC 19.10-1981 Part 10 is an acceptable alternative to Method 
3B (incorporated by reference, see Sec. 63.14).
    (4) Use Method 4 of appendix A to 40 CFR part 60, to determine stack 
gas moisture.
    (5) Methods for determining gas volumetric flow rate, dry molecular 
weight, and stack gas moisture must be performed, as applicable, during 
each test run.
    (b) Measure total gaseous organic mass emissions as carbon at the 
inlet and outlet of the add-on control device simultaneously, using 
either Method 25 or 25A of appendix A to 40 CFR part 60, as specified in 
paragraphs (b)(1) through (3) of this section. You must use the same 
method for both the inlet and outlet measurements.
    (1) Use Method 25 of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be more than 50 parts per million at the 
control device outlet.
    (2) Use Method 25A of appendix A to 40 CFR part 60 if the add-on 
control device is an oxidizer, and you expect the total gaseous organic 
concentration as carbon to be 50 ppm or less at the control device 
outlet.
    (c) For each test run, determine the total gaseous organic emissions 
mass flow rates for the inlet and the outlet of the add-on control 
device, using Equation 1 of this section. If there is more than one 
inlet or outlet to the add-on control device, you must calculate the 
total gaseous organic mass flow rate using Equation 1 of this section 
for each inlet and each outlet and then total all of the inlet emissions 
and total all of the outlet emissions.
[GRAPHIC] [TIFF OMITTED] TR27MY03.005

Where:

Mf = total gaseous organic emissions mass flow rate, kg/hour 
(kg/h)
Cc = concentration of organic compounds as carbon in the vent 
gas, as determined by Method 25 or Method 25A, parts per million by 
volume (ppmv), dry basis
Qsd = volumetric flow rate of gases entering or exiting the 
add-on control device, as determined by Method 2, 2A, 2C, 2D, 2F, or 2G, 
dry standard cubic meters/hour (dscm/h)
0.0416 = conversion factor for molar volume, kg-moles per cubic meter 
(mol/m\3\) (@ 293 Kelvin [K] and 760 millimeters of mercury [mmHg]).
    (d) For each test run, determine the add-on control device organic 
emissions destruction or removal efficiency, using Equation 2 of this 
section:

[[Page 864]]

[GRAPHIC] [TIFF OMITTED] TR27MY03.006

Where:

DRE = organic emissions destruction or removal efficiency of the add-on 
control device, percent
Mfi = total gaseous organic emissions mass flow rate at the 
inlet(s) to the add-on control device, using Equation 1 of this section, 
kg/h
Mfo = total gaseous organic emissions mass flow rate at the 
outlet(s) of the add-on control device, using Equation 1 of this 
section, kg/h.
    (e) Determine the emission destruction or removal efficiency of the 
add-on control device as the average of the efficiencies determined in 
the three test runs and calculated in Equation 2 of this section.



Sec. 63.9324  How do I establish the emission capture system and add-on control device operating limits during the performance test?

    During the performance test required by Sec. 63.9310, you must 
establish the operating limits required by Sec. 63.9302 according to 
this section, unless you have received approval for alternative 
monitoring and operating limits under Sec. 63.8(f) as specified in 
Sec. 63.9302.
    (a) Thermal oxidizers. If your add-on control device is a thermal 
oxidizer, establish the operating limits according to paragraphs (a)(1) 
and (2) of this section.
    (1) During the performance test, you must monitor and record the 
combustion temperature at least once every 15 minutes during each of the 
three test runs. You must monitor the temperature in the firebox of the 
thermal oxidizer or immediately downstream of the firebox before any 
substantial heat exchange occurs.
    (2) Use the data collected during the performance test to calculate 
and record the average combustion temperature maintained during the 
performance test. This average combustion temperature is the minimum 
operating limit for your thermal oxidizer.
    (b) Catalytic oxidizers. If your add-on control device is a 
catalytic oxidizer, establish the operating limits according to either 
paragraphs (b)(1) and (2) or paragraphs (b)(3) and (4) of this section.
    (1) During the performance test, you must monitor and record the 
temperature just before the catalyst bed and the temperature difference 
across the catalyst bed at least once every 15 minutes during each of 
the three test runs.
    (2) Use the data collected during the performance test to calculate 
and record the average temperature just before the catalyst bed and the 
average temperature difference across the catalyst bed maintained during 
the performance test. These are the minimum operating limits for your 
catalytic oxidizer.
    (3) As an alternative to monitoring the temperature difference 
across the catalyst bed, you may monitor the temperature at the inlet to 
the catalyst bed and implement a site-specific inspection and 
maintenance plan for your catalytic oxidizer as specified in paragraph 
(b)(4) of this section. During the performance test, you must monitor 
and record the temperature just before the catalyst bed at least once 
every 15 minutes during each of the three test runs. Use the data 
collected during the performance test to calculate and record the 
average temperature just before the catalyst bed during the performance 
test. This is the minimum operating limit for your catalytic oxidizer.
    (4) You must develop and implement an inspection and maintenance 
plan for your catalytic oxidizer(s) for which you elect to monitor 
according to paragraph (b)(3) of this section. The plan must address, at 
a minimum, the elements specified in paragraphs (b)(4)(i) through (iii) 
of this section.
    (i) Annual sampling and analysis of the catalyst activity (i.e., 
conversion efficiency) following the manufacturer's or catalyst 
supplier's recommended procedures.
    (ii) Monthly inspection of the oxidizer system, including the burner 
assembly and fuel supply lines for problems and, as necessary, adjust 
the equipment to assure proper air-to-fuel mixtures.
    (iii) Annual internal and monthly external visual inspection of the 
catalyst bed to check for channeling, abrasion, and settling. If 
problems are found, you

[[Page 865]]

must take corrective action consistent with the manufacturer's 
recommendation and conduct a new performance test to determine 
destruction efficiency according to Sec. 63.9323.
    (c) Emission capture system. For each capture device that is not 
part of a PTE that meets the criteria of Sec. 63.9322(a), establish an 
operating limit for either the gas volumetric flow rate or duct static 
pressure, as specified in paragraphs (c)(1) and (2) of this section. The 
operating limit for a PTE is specified in Table 3 to this subpart.
    (1) During the capture efficiency determination required by 
Sec. 63.9310, you must monitor and record either the gas volumetric flow 
rate or the duct static pressure for each separate capture device in 
your emission capture system at least once every 15 minutes during each 
of the three test runs at a point in the duct between the capture device 
and the add-on control device inlet.
    (2) Calculate and record the average gas volumetric flow rate or 
duct static pressure for the three test runs for each capture device. 
This average gas volumetric flow rate or duct static pressure is the 
minimum operating limit for that specific capture device.



Sec. 63.9330  How do I demonstrate initial compliance with the emission limitation?

    (a) You must demonstrate initial compliance with the emission 
limitation that applies to you according to Table 3 to this subpart.
    (b) You must submit the Notification of Compliance Status containing 
results of the initial compliance demonstration according to the 
requirements in Sec. 63.9345(c).

                   Continuous Compliance Requirements



Sec. 63.9335  How do I monitor and collect data to demonstrate continuous compliance?

    (a) Except for monitor malfunctions, associated repairs, and 
required quality assurance or quality control activities (including, as 
applicable, calibration drift checks and required zero and high-level 
adjustments of the monitoring system), you must conduct all monitoring 
in continuous operation at all times the engine test cell/stand is 
operating.
    (b) Do not use data recorded during monitor malfunctions, associated 
repairs, and required quality assurance or quality control activities 
for meeting the requirements of this subpart, including data averages 
and calculations. You must use all the data collected during all other 
periods in assessing the performance of the emission control device or 
in assessing emissions from the new or reconstructed affected source.



Sec. 63.9340  How do I demonstrate continuous compliance with the emission limitations?

    (a) You must demonstrate continuous compliance with the emission 
limitation in Table 1 to this subpart that applies to you according to 
methods specified in Table 5 to this subpart.
    (b) You must report each instance in paragraphs (b)(1) and (2) of 
this section. These instances are deviations from the emission 
limitation in this subpart and must be reported according to the 
requirements in Sec. 63.9350.
    (1) You must report each instance in which you did not meet the 
emission limitation that applies to you.
    (2) You must report each instance in which you did not meet the 
requirements in Table 7 to this subpart that apply to you.
    (c) Startups, shutdowns, and malfunctions. During periods of SSM of 
control device and associated monitoring equipment, you must operate in 
accordance with your SSMP.
    (1) Consistent with Secs. 63.6(e) and 63.7(e)(1), deviations that 
occur during a period of SSM of control devices and associated 
monitoring equipment are not violations if you demonstrate to the 
Administrator's satisfaction that you were operating in accordance with 
the SSMP.
    (2) The Administrator will determine whether deviations that occur 
during a period of SSM of control devices and associated monitoring 
equipment are violations, according to the provisions in Sec. 63.6(e).

subpart, you must submit an Initial Notification not later than 120 
calendar days after you become subject to this subpart.
    (3) If you are required to submit an Initial Notification but are 
otherwise not affected by the requirements of this subpart, in 
accordance with Sec. 63.9290(c), your notification should include the 
information in Sec. 63.9(b)(2)(i) through (v) and a statement that your 
new or reconstructed engine test cell/stand has no additional 
requirements and explain the basis of the exclusion (for example, that 
the test cell/stand is used exclusively for testing internal combustion 
engines with rated power of less than 25 hp (19 kW)).
    (c) If you are required to comply with the emission limitations in 
Table 1 to this subpart, you must submit a Notification of Compliance 
Status according to Sec. 63.9(h)(2)(ii). For each initial compliance 
demonstration with the emission limitation, you must submit the 
Notification of Compliance Status before the close of business on the 
30th calendar day following the completion of the initial compliance 
demonstration.
    (d) You must submit a notification of initial performance evaluation 
of your CEMS or performance testing of your control device at least 60 
calendar days before the performance testing/evaluation is scheduled to

Sec. 63.9350  What reports must I submit and when?

    (a) If you own or operate a new or reconstructed affected source 
that must meet the emission limitation, you must submit a semiannual 
compliance report according to Table 6 to this subpart by the applicable 
dates specified in paragraphs (a)(1) through (6) of this section, unless 
the Administrator has approved a different schedule.
    (1) The first semiannual compliance report must cover the period 
beginning on the compliance date specified in Sec. 63.9295 and ending on 
June 30 or December 31, whichever date is the first date following the 
end of the first calendar half after the compliance date specified in

    CAA means the Clean Air Act (42 U.S.C. 7401 et seq., as amended by 
Public Law 101-549, 104 Statute 2399).
    Area source means any stationary source of HAP that is not a major 
source as defined in this part.
    Combustion turbine engine means a device in which air is compressed 
in a compressor, enters a combustion chamber, and is compressed further 
by the combustion of fuel injected into the combustion chamber. The hot 
compressed combustion gases then expand over a series of curved vanes or 
blades arranged on a central spindle that rotates.
    Deviation means any instance in which an affected source subject to 
this subpart, or an owner or operator of such a source:
    (1) Fails to meet any requirement or obligation established by this 
subpart, including but not limited to any emission limitations;
    (2) Fails to meet any term or condition that is adopted to implement 
an applicable requirement in this subpart and that is included in the 
operating permit for any affected source required to obtain such a 
permit; or
    (3) Fails to meet any emission limitation in this subpart during 
malfunction, regardless or whether or not such failure is permitted by 
this subpart.
    Engine means any internal combustion engine, any combustion turbine 
engine, or any rocket engine.
    Engine Test Cell/Stand means any apparatus used for testing 
uninstalled stationary or uninstalled mobile (motive) engines.
    Hazardous Air Pollutant (HAP) means any air pollutant listed in or 
pursuant to section 112(b) of the CAA.

[[Page 870]]

    Internal combustion engine means a device in which air enters a 
combustion chamber, is mixed with fuel, compressed in the chamber, and 
combusted. Fuel may enter the combustion chamber with the air or be 
injected into the combustion chamber. Expansion of the hot combustion 
gases in the chamber rotates a shaft, either through a reciprocating or 
rotary action. For purposes of this subpart, this definition does not 
include combustion turbine engines.
    Major source, as used in this subpart, shall have the same meaning 
as in Sec. 63.2.
    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.
    Rated power means the maximum power output of an engine in use.
    Potential to emit means the maximum capacity of a stationary source 
to emit a pollutant under its physical and operational design. Any 
physical or operational limitation on the capacity of the stationary 
source to emit a pollutant, including air pollution control equipment 
and restrictions on hours of operation or on the type or amount of 
material combusted, stored, or processed, shall be treated as part of 
its design if the limitation or the effect it would have on emissions is 
federally enforceable.
    Responsible official means responsible official as defined by 40 CFR 
70.2.
    Rocket engine means a device consisting of a combustion chamber in 
which materials referred to as propellants, which provide both the fuel 
and the oxygen for combustion, are burned. Combustion gases escape 
through a nozzle, providing thrust.
    Uninstalled engine means an engine not installed in, or an 
integrated part of, the final product.

    Source: 67 FR 64506, Oct. 18, 2002, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.9480  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for friction materials manufacturing facilities 
that use a solvent-based process. This subpart also establishes 
requirements to demonstrate initial and continuous compliance with all 
applicable emission limitations in this subpart.



Sec. 63.9485  Am I subject to this subpart?

    (a) You are subject to this subpart if you own or operate a friction 
materials manufacturing facility (as defined in Sec. 63.9565) that is 
(or is part of) a major source of hazardous air pollutants (HAP) 
emissions on the first compliance date that applies to you, as specified 
in Sec. 63.9495. Your friction materials manufacturing facility is a 
major source of HAP if it emits or has the potential to emit any single 
HAP at a rate of 9.07 megagrams (10 tons) or more per year or any 
combination of HAP at a rate of 22.68 megagrams (25 tons) or more per 
year.
    (b) The requirements in this subpart do not apply to research and 
development facilities, as defined in section 112(c)(7) of the Clean Air 
Act.



Sec. 63.9490  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at your friction materials manufacturing facility.
    (b) The affected source covered by this subpart is each new, 
reconstructed, or existing solvent mixer (as defined in Sec. 63.9565) at 
your friction materials manufacturing facility.
    (c) A solvent mixer at your friction materials manufacturing 
facility is new if you commence construction of the solvent mixer after 
October 18, 2002. An affected source is reconstructed if it meets the 
definition of ``reconstruction'' in Sec. 63.2, and reconstruction is 
commenced after October 18, 2002.
    (d) A solvent mixer at your friction materials manufacturing 
facility is existing if it is not new or reconstructed.



Sec. 63.9495  When do I have to comply with this subpart?

    (a) If you have an existing solvent mixer, you must comply with each 
of the requirements for existing sources no later than October 18, 2005.
    (b) If you have a new or reconstructed solvent mixer and its initial 
startup date is after October 18, 2002, you must comply with the 
requirements for new and reconstructed sources upon initial startup.
    (c) If your friction materials manufacturing facility is an area 
source that increases its emissions or its potential to emit such that 
it becomes a (or part of a) major source of HAP emissions, then 
paragraphs (c)(1) and (2) of this section apply.
    (1) For any portion of the area source that becomes a new or 
reconstructed affected source, you must comply with the requirements for 
new and reconstructed sources upon startup or no later than October 18, 
2002, whichever is later.
    (2) For any portion of the area source that becomes an existing 
affected source, you must comply with the requirements for existing

source or no later than October 18, 2005, whichever is later.
    (d) You must meet the notification and schedule requirements in 
Sec. 63.9535. Several of the notifications must be submitted before the 
compliance date for your affected source.

                          Emission Limitations



Sec. 63.9500  What emission limitations must I meet?

    (a) For each new, reconstructed, or existing large solvent mixer at 
your friction materials manufacturing facility, you must limit HAP 
solvent emissions to the atmosphere to no more than 30 percent of that 
which would otherwise be emitted in the absence of

[[Page 883]]

solvent recovery and/or solvent substitution, based on a 7-day block 
average.
    (b) For each new, reconstructed, or existing small solvent mixer at 
your friction materials manufacturing facility, you must limit HAP 
solvent emissions to the atmosphere to no more than 15 percent of that 
which would otherwise be emitted in the absence of solvent recovery and/
or solvent substitution, based on a 7-day block average.

malfunction plan according to the provisions in Sec. 63.6(e)(3).

              Initial Compliance Demonstration Requirements



Sec. 63.9510  By what date must I conduct my initial compliance demonstration?

    (a) If you use a solvent recovery system and/or solvent 
substitution, you must conduct your initial compliance demonstration 
within 7 calendar days after the compliance date that is specified for 
your source in Sec. 63.9495.
    (b) If you use a control technique other than a solvent recovery 
system and/or solvent substitution, you must comply with the provisions 
in Sec. 63.9570.



Sec. 63.9515  How do I demonstrate initial compliance with the emission limitation that applies to me?

    (a) You have demonstrated initial compliance for each new, 
reconstructed, or existing large solvent mixer subject to the emission 
limitation in Sec. 63.9500(a) if the HAP solvent discharged to the 
atmosphere during the first 7 days after the compliance date, determined 
according to the provisions in Sec. 63.9520, does not exceed a 7-day 
block average of 30 percent of that which would otherwise be emitted in 
the absence of solvent recovery and/or solvent substitution.
    (b) You have demonstrated initial compliance for each new, 
reconstructed, or existing small solvent mixer subject to the emission 
limitation in Sec. 63.9500(b) if the HAP solvent discharged to the 
atmosphere during the first 7 days after the compliance date, determined 
according to the provisions in Sec. 63.9520, does not exceed a 7-day 
block average of 15 percent of that which would otherwise be emitted in 
the absence of solvent recovery and/or solvent substitution.
    (c) You must submit a notification of compliance status containing 
the results of the initial compliance demonstration according to 
Sec. 63.9535(e).



Sec. 63.9520  What procedures must I use to demonstrate initial compliance?

    (a) If you use a solvent recovery system, you must use the 
procedures in paragraphs (a)(1) through (8) of this section to 
demonstrate initial compliance with the emission limitations in 
Sec. 63.9500(a) and (b).
    (1) Record the date and time of each mix batch.
    (2) Record the identity of each mix batch using a unique batch ID, 
as defined in Sec. 63.9565.
    (3) Measure and record the weight of HAP solvent loaded into the 
solvent mixer for each mix batch.
    (4) Measure and record the weight of HAP solvent recovered for each 
mix batch.
    (5) If you use a solvent recovery system, you must determine the 
percent of HAP solvent discharged to the atmosphere for each mix batch 
according to Equation 1 of this section as follows:
(Eq. 1)
[GRAPHIC] [TIFF OMITTED] TR18OC02.002

Where:

Pb = Percent of HAP solvent discharged to the atmosphere for 
each mix batch, percent;
Srec = Weight of HAP solvent recovered for each mix batch, 
lb;
Smix = Weight of HAP solvent loaded into the solvent mixer 
for each mix batch, lb.


[[Page 884]]


    (6) If you use solvent substitution for a mix batch, you must record 
the use of a non-HAP material as a substitute for a HAP solvent for that 
mix batch and assign a value of 0 percent to the percent of HAP solvent 
discharged to the atmosphere for that mix batch (Pb).
    (7) Determine the 7-day block average percent of HAP solvent 
discharged to the atmosphere according to Equation 2 of this section as 
follows:
[GRAPHIC] [TIFF OMITTED] TR18OC02.003

Where:

%P7 = 7-day block average percent of HAP solvent discharged 
to the atmosphere, percent;
i = mix batch;
n = number of mix batches in 7-day block average.

    (8) Have valid data for at least 90 percent of the mix batches over 
the 7-day averaging period.
    (b) If you use a control technique other than a solvent recovery 
system and/or solvent substitution, you may apply to EPA for approval to 
use an alternative method of demonstrating compliance with the emission 
limitations for solvent mixers in Sec. 63.9500(a) and (b), as provided 
in Sec. 63.9570.



Sec. 63.9525  What are the installation, operation, and maintenance requirements for my weight measurement device?

    (a) If you use a solvent recovery system, you must install, operate,

solvent loaded into the solvent mixer and the weight of HAP solvent 
recovered for each mix batch.
    (b) For each weight measurement device required by this section, you 
must develop and submit for approval a site-specific monitoring plan 
that addresses the requirements of paragraphs (b)(1) through (6) of this 
section:
    (1) Procedures for installing the weight measurement device;
    (2) The minimum accuracy of the weight measurement device in pounds 
and as a percent of the average weight of solvent to be loaded into the 
solvent mixer;
    (3) Site-specific procedures for how the measurements will be made;
    (4) How the measurement data will be recorded, reduced, and stored;
    (5) Procedures and acceptance criteria for calibration of the weight 
measurement device; and
    (6) How the measurement device will be maintained, including a 
routine maintenance schedule and spare parts inventory list.
    (c) The site-specific monitoring plan required in paragraph (b) of 
this section must include, at a minimum, the requirements of paragraphs 
(c)(1) through (3) of this section:
    (1) The weight measurement device must have a minimum accuracy of 
[plusmn]0.05 kilograms ([plusmn]0.1 pounds) or [plusmn]1 percent of the 
average weight of solvent to be loaded into the solvent mixer, whichever 
is greater.
    (2) An initial multi-point calibration of the weight measurement 
device must be made using 5 points spanning the expected range of weight 
measurements before the weight measurement device can be used. The 
manufacturer's calibration results can be used to meet this requirement.
    (3) Once per day, an accuracy audit must be made using a single 
Class F calibration weight that corresponds to 20 to 80 percent of the 
average weight of solvent to be loaded into the solvent mixer. If the 
weight measurement device cannot reproduce the value of the calibration 
weight within [plusmn]0.05 kilograms (0.1 pounds) or [plusmn]1 percent 
of the average weight of solvent to be loaded into the solvent mixer, 
whichever is greater, the scale must be recalibrated before being used 
again. The recalibration must be performed with at least five Class F 
calibration weights spanning the expected range of weight measurements.
    (d) You must operate and maintain the weight measurement device 
according to the site-specific monitoring plan.
    (e) You must maintain records of all maintenance activities, 
calibrations, and calibration audits.

document conformance with these requirements.
    (2) For new, reconstructed, or existing large solvent mixers, 
maintain the 7-day block average percent of HAP solvent discharged to 
the atmosphere at or below 30 percent of that which would otherwise be 
emitted in the absence of solvent recovery and/or solvent substitution.
    (3) For new, reconstructed, or existing small solvent mixers, 
maintain the 7-day block average percent of HAP solvent discharged to 
the atmosphere at or below 15 percent of that which would otherwise be 
emitted in the absence of solvent recovery and/or solvent substitution.
    (b) If you use a control technique other than a solvent recovery 
system and/or solvent substitution, you must demonstrate continuous 
compliance with the emission limitations for solvent mixers in 
Sec. 63.9500(a) and (b) according to the provisions in Sec. 63.9570.
    (c) You must report each instance in which you did not meet the 
emission limitations for solvent mixers in Sec. 63.9500(a) and (b). This 
includes periods of startup, shutdown, or malfunction. These instances 
are deviations from the emission limitations in this subpart. These 
deviations must be reported according to the requirements in 
Sec. 63.9540.

Trace amounts of HAP solvents in resins or other friction ingredients do 
not qualify mixers as solvent mixers.
    Solvent recovery system means equipment used for the purpose of 
recovering the HAP solvent from the exhaust stream. An example of a 
solvent recovery system is a condenser.
    Solvent substitution means substitution of a non-HAP material for a 
HAP solvent.
    Startup means bringing equipment online and starting the production 
process.
    Startup, shutdown, and malfunction plan means a plan developed 
according to the provisions of Sec. 63.6(e)(3).



Sec. 63.9570  How do I apply for alternative compliance requirements?

    (a) If you use a control technique other than a solvent recovery 
system and/or solvent substitution, you may request approval to use an 
alternative method of demonstrating compliance with the emission 
limitations in Sec. 63.9500(a) and (b) according to the procedures in 
this section.
    (b) You can request approval to use an alternative method of 
demonstrating compliance in the initial notification for existing 
sources, the notification of construction or reconstruction for new 
sources, or at any time.
    (c) You must submit a description of the proposed testing, 
monitoring, recordkeeping, and reporting that will be used and the 
proposed basis for demonstrating compliance.
    (1) If you have not previously performed testing, you must submit a 
proposed test plan. If you are seeking permission to use an alternative 
method of compliance based on previously performed testing, you must 
submit the results of testing, a description of the procedures followed 
in testing, and a description of pertinent conditions during testing.
    (2) You must submit a monitoring plan that includes a description of 
the control technique, test results

[[Page 889]]

verifying the performance of the control technique, the appropriate 
operating parameters that will be monitored, and the frequency of 
measuring and recording to establish continuous compliance with the 
emission limitations in Sec. 63.9500(a) and (b). You must also include 
the proposed performance specifications and quality assurance procedures 
for the monitors. The monitoring plan is subject to the Administrator's 
approval. You must install, calibrate, operate, and maintain the 
monitors in accordance with the monitoring plan approved by the 
Administrator.
    (d) Use of the alternative method of demonstrating compliance must 
not begin until approval is granted by the Administrator.

Subpart SSSSS--National Emission Standards for Hazardous Air Pollutants 
                  for Refractory Products Manufacturing

    Source: 68 FR 18747, Apr. 16, 2003, unless otherwise noted.

                        What This Subpart Covers



Sec. 63.9780  What is the purpose of this subpart?

    This subpart establishes national emission standards for hazardous 
air pollutants (NESHAP) for refractory products manufacturing 
facilities. This subpart also establishes requirements to demonstrate 
initial and continuous compliance with the emission limitations.



Sec. 63.9782  Am I subject to this subpart?

    You are subject to this subpart if you own or operate a refractory 
products manufacturing facility that is, is located at, or is part of, a 
major source of hazardous air pollutant (HAP) emissions according to the 
criteria in paragraphs (a) and (b) of this section.
    (a) A refractory products manufacturing facility is a plant site 
that manufactures refractory products (refractory bricks, refractory 
shapes, monolithics, kiln furniture, crucibles, and other materials used 
for lining furnaces and other high temperature process units), as 
defined in Sec. 63.9824. Refractory products manufacturing facilities 
typically process raw material by crushing, grinding, and screening; 
mixing the processed raw materials with binders and other additives; 
forming the refractory mix into shapes; and drying and firing the 
shapes.
    (b) 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 or any combination of HAP at a rate of 22.68 megagrams 
(25 tons) or more per year.



Sec. 63.9784  What parts of my plant does this subpart cover?

    (a) This subpart applies to each new, reconstructed, or existing 
affected source at a refractory products manufacturing facility.
    (b) The existing affected sources are shape dryers, curing ovens, 
and kilns that are used to manufacture refractory products that use 
organic HAP; shape preheaters, pitch working tanks, defumers, and coking 
ovens that are used to produce pitch-impregnated refractory products; 
kilns that are used to manufacture chromium refractory products; and 
kilns that are used to manufacture clay refractory products.
    (c) The new or reconstructed affected sources are shape dryers, 
curing ovens, and kilns that are used to manufacture refractory products 
that use organic HAP; shape preheaters, pitch working tanks, defumers, 
and coking ovens used to produce pitch-impregnated refractory products; 
kilns that are used to

[[Page 891]]

manufacture chromium refractory products; and kilns that are used to 
manufacture clay refractory products.
    (d) Shape dryers, curing ovens, kilns, coking ovens, defumers, shape 
preheaters, and pitch working tanks that are research and development 
(R&D) process units are not subject to the requirements of this subpart. 
(See definition of research and development process unit in 
Sec. 63.9824).
    (e) A source is a new affected source if you began construction of 
the affected source after June 20, 2002, and you met the applicability 
criteria at the time you began construction.
    (f) An affected source is reconstructed if you meet the criteria as 
defined in Sec. 63.2.
    (g) An affected source is existing if it is not new or 
reconstructed.



Sec. 63.9786  When do I have to comply with this subpart?

    (a) If you have a new or reconstructed affected source, you must 
comply with this subpart according to paragraphs (a)(1) and (2) of this 
section.
    (1) If the initial startup of your affected source is before April 
16, 2003, then you must comply with the emission limitations for new and 
reconstructed sources in this subpart no later than April 16, 2003.
    (2) If the initial startup of your affected source is after April 
16, 2003, then you must comply with the emission limitations for new and 
reconstructed sources in this subpart upon initial startup of your 
affected source.
    (b) If you have an existing affected source, you must comply with 
the emission limitations for existing sources no later than April 17, 
2006.
    (c) You must be in compliance with this subpart when you conduct a 
performance test on an affected source.
    (d) If you have an existing area source that increases its emissions 
or its potential to emit such that it becomes a major source of HAP, you 
must be in compliance with this subpart according to paragraphs (d)(1) 
and (2) of this section.
    (1) Any portion of the existing facility 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 existing facility must be in compliance 
with this subpart by 3 years after the date the area source becomes a 
major source.
    (e) If you have a new area source (i.e., an area source for which 
construction or reconstruction was commenced after June 20, 2002) that 
increases its emissions or its potential to emit such that it becomes a 
major source of HAP, you must be in compliance with this subpart upon 
initial startup of your affected source as a major source.
    (f) You must meet the notification requirements in Sec. 63.9812 
according to the schedule in Sec. 63.9812 and in 40 CFR part 63, subpart 
A. Some of the notifications must be submitted before you are required 
to comply with the emission limitations in this subpart.

satisfy the accuracy requirements of paragraph (a)(15) of this section. 
While the process and control device that is monitored by your flow rate 
CPMS are operating normally, record concurrently and compare the flow 
rates measured by your flow rate CPMS and the calibrated flow rate 
measurement device. Using the calibrated flow rate measurement device as 
the reference, the flow rate measured by your CPMS must be within the 
accuracy specified in paragraph (d)(1) of this section.
    (ii) Perform any of the initial validation methods for liquid flow 
rate CPMS specified in performance specifications for CPMS established 
in 40 CFR part 60, appendix B.

quarterly, according to the requirements in paragraph (d)(4)(i), (ii), 
or (iii) of this section.
    (i) If your flow rate CPMS includes a redundant sensor, record three 
pairs of concurrent flow rate measurements within a 24-hour period. Each 
pair of concurrent measurements must consist of a flow rate measurement 
by each of the two flow rate sensors. The minimum time interval between 
any two such pairs of consecutive flow rate measurements is 1 hour. The 
measurements must be taken during periods when the process and control 
device that is monitored by your flow rate CPMS are operating normally.

where it is easily recognized by plant operating personnel.
    (6) For positive pressure fabric filter systems, a bag leak detector 
must be installed in each baghouse compartment or cell.
    (7) For negative pressure or induced air fabric filters, the bag 
leak detector must be installed downstream of the fabric filter.
    (8) Where multiple detectors are required, the system's 
instrumentation and alarm may be shared among detectors.
    (9) The baseline output must be established by adjusting the range 
and the averaging period of the device and establishing the alarm set 
points and the alarm delay time according to section 5.0 of the ``Fabric 
Filter Bag Leak Detection Guidance.''
    (10) Following initial adjustment of the system, the owner or 
operator must not adjust the sensitivity or range, averaging period, 
alarm set points, or alarm delay time except as detailed in the OM&M 
plan. In no case may the sensitivity be increased by more than 100 
percent or decreased by more than 50 percent over a 365-day period 
unless such adjustment follows a complete fabric filter inspection that 
demonstrates that the fabric filter is in good operating condition. You 
must record each adjustment of your bag leak detection system.
    (11) Record the results of each inspection, calibration, and 
validation check.
    (g) For each lime feed rate measurement device that is used to 
monitor the lime feed rate of a dry injection fabric filter (DIFF) or 
dry lime scrubber/fabric filter (DLS/FF), or the chemical feed rate of a 
wet scrubber, you must meet the requirements in paragraph (a) of this

Sec. 63.9806  How do I demonstrate initial compliance with the emission limits, operating limits, and work practice standards?

    (a) You must demonstrate initial compliance with each emission limit 
that applies to you according to the requirements specified in Table 5 
to this subpart.
    (b) You must establish each site-specific operating limit in Table 2 
to this subpart that applies to you according to the requirements 
specified in Sec. 63.9800 and Table 4 to this subpart.
    (c) You must demonstrate initial compliance with each work practice 
standard that applies to you according to the requirements specified in 
Table 6 to this subpart.
    (d) You must submit the Notification of Compliance Status containing 
the results of the initial compliance demonstration according to the 
requirements in Sec. 63.9812(e).

                   Continuous Compliance Requirements



Sec. 63.9808  How do I monitor and collect data to demonstrate continuous compliance?

    (a) You must monitor and collect data according to this section.

[[Page 902]]

    (b) At all times, you must maintain your monitoring systems 
including, but not limited to, maintaining necessary parts for routine 
repairs of the monitoring equipment.
    (c) Except for, as applicable, monitoring system malfunctions, 
associated repairs, and required quality assurance or quality control 
activities, you must monitor continuously whenever your affected process 
unit is operating. For purposes of calculating data averages, you must 
not use data recorded during monitoring system malfunctions, associated 
repairs, and required quality assurance or quality control activities. 
You must use all the data collected during all other periods in 
assessing compliance. A monitoring system malfunction is any sudden, 
infrequent, not reasonably preventable failure of the monitoring system 
to provide valid data. Monitoring system malfunctions include out of 
control continuous monitoring systems (CMS), such as a CPMS. Any 
averaging period for which you do not have valid monitoring data as a 
result of a monitoring system malfunction and for which such data are 
required constitutes a deviation, and you must notify the Administrator 
in accordance with Sec. 63.9814(e). Monitoring system failures are 
different from monitoring system malfunctions in that they are caused in 
part by poor maintenance or careless operation. Any period for which 
there is a monitoring system failure and data are not available for 
required calculations constitutes a deviation and you must notify the 
Administrator in accordance with Sec. 63.9814(e).



Sec. 63.9810  How do I demonstrate continuous compliance with the emission limits, operating limits, and work practice standards?

    (a) You must demonstrate continuous compliance with each emission 
limit specified in Table 1 to this subpart that applies to you according 
to the requirements specified in Table 7 to this subpart.
    (b) You must demonstrate continuous compliance with each operating 
limit specified in Table 2 to this subpart that applies to you according 
to the requirements specified in Table 8 to this subpart.
    (c) You must demonstrate continuous compliance with each work 
practice standard specified in Table 3 to this subpart that applies to 
you according to the requirements specified in Table 9 to this subpart.
    (d) For each affected source that is equipped with an add-on APCD 
that is not addressed in Table 2 to this subpart or that is using 
process changes as a means of meeting the emission limits in Table 1 to 
this subpart, you must demonstrate continuous compliance with each 
emission limit in Table 1 to this subpart and each operating limit 
established as required in Sec. 63.9800(i)(3) according to the methods 
specified in your approved alternative monitoring methods request as 
described in Sec. 63.9800(i)(2).
    (e) You must report each instance in which you did not meet each 
emission limit and each operating limit in this subpart that applies to 
you. This includes periods of startup, shutdown, and malfunction. These 
instances are deviations from the emission limitations in this subpart. 
These deviations must be reported according to the requirements in 
Sec. 63.9814.
    (1) During periods of startup, shutdown, and malfunction, you must 
operate according to your SSMP.
    (2) Consistent with Secs. 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 according to your SSMP and your OM&M plan. 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).

relative PM loadings.
    Basket means the metal container used to hold refractory shapes for 
pitch impregnation during the shape preheating, impregnation, defuming, 
and, if applicable, coking processes.
    Batch process means a process in which a set of refractory shapes is

during which none of the refractory shapes being processed are added or 
removed. A batch process does not operate continuously.
    Binder means a substance added to a granular material to give it 
workability and green or dry strength.
    Catalytic oxidizer means an add-on air pollution control device that 
is designed specifically to destroy organic compounds in a process 
exhaust gas stream by catalytic incineration. A catalytic oxidizer 
includes a bed of catalyst media through which the process exhaust 
stream passes to promote combustion and incineration at a lower 
temperature than would be possible without the catalyst.

support, or position ceramic or refractory products in a kiln during the 
firing process.
    Maximum organic HAP processing rate means the combination of process 
and refractory product formulation that has the greatest potential to 
emit organic HAP. The maximum organic HAP processing rate is a function 
of the organic HAP processing rate, process operating temperature, and 
other process operating parameters that affect emissions of organic HAP. 
(See also the definition of organic HAP processing rate.)
    Organic HAP processing rate means the rate at which the mass of

and additives used in a refractory mix; the amounts of those resins, 
binders, and additives in the refractory mix; and the rate at which the 
refractory shapes formed from the refractory mix are processed in an 
affected thermal process unit. For continuous process units, the organic 
HAP processing rate is expressed in units of mass of organic HAP per 
unit of time (e.g., pounds per hour). For batch process units, the 
organic HAP processing rate is expressed in units of mass of organic HAP 
per unit mass of refractory shapes processed during the batch process 
cycle (e.g., pounds per ton).

emissions of the applicable pollutant that is greater than any other 
period of consecutive hourly mass emissions for the same pollutant over 
the course of a specified batch process cycle, as defined in paragraphs 
(1) and (2) of this definition. The peak emissions period is a function 
of the rate at which the temperature of the refractory shapes is 
increased, the mass and loading configuration of the shapes in the 
process unit, the constituents of the refractory mix, and the type of 
pollutants emitted.
    (1) The 3-hour peak THC emissions period is the period of 3 
consecutive hours over which the sum of the hourly

[[Page 909]]

THC mass emissions rates is greater than the sum of the hourly THC mass 
emissions rates for any other period of 3 consecutive hours during the 
same batch process cycle.
    (2) The 3-hour peak HF emissions period is the period of 3 
consecutive hours over which the sum of the hourly HF mass emissions 
rates is greater than the sum of the hourly HF mass emissions rates for 
any other period of 3 consecutive hours during the same batch process 
cycle.
    Period of natural gas curtailment or supply interruption means a 
period of time during which the supply of natural gas to an affected 
facility is halted for reasons beyond the control of the facility. An 
increase in the cost or unit price of natural gas does not constitute a 
period of natural gas curtailment or supply interruption.

impregnation cycles; and transferring pitch to and from the autoclave 
during the impregnation step in manufacturing pitch-impregnated 
refractory products.
    Plant site means all contiguous or adjoining property that is under 
common control, including properties that are separated only by a road 
or other public right-of-way. Common control includes properties that 
are owned, leased, or operated by the same entity, parent entity, 
subsidiary, or any combination thereof.
    Redundant sensor means a second sensor or a back-up sensor that is 
integrated into a CPMS and is used to check the parameter value (e.g., 
temperature, pressure) measured by the primary sensor of the CPMS.
    Refractory product means nonmetallic materials containing less than 
50 percent carbon by weight and having those chemical and physical 
properties that make them applicable for structures, or as components of 
systems, that are exposed to environments above 538 [deg]C (1000 
[deg]F). This definition includes, but is not limited to: refractory 
bricks, kiln furniture, crucibles, refractory ceramic fiber, and other 
materials used as linings for boilers, kilns, and other processing units 
and equipment where extremes of temperature, corrosion, and abrasion 
would destroy other materials.

                   Appendix A to Part 63--Test Methods

   Method 301--Field Validation of Pollutant Measurement Methods from 
                           Various Waste Media

                     1. Applicability and principle

    1.1 Applicability. This method, as specified in the applicable 
subpart, is to be used whenever a source owner or operator (hereafter 
referred to as an ``analyst'') proposes a test method to meet a U.S. 
Environmental Protection Agency (EPA) requirement in the absence of a 
validated method. This Method includes procedures for determining and 
documenting the quality, i.e., systematic error (bias) and random error 
(precision), of the measured concentrations from an effected source. 
This method is applicable to various waste media (i.e., exhaust gas, 
wastewater, sludge, etc.).
    1.1.1 If EPA currently recognizes an appropriate test method or 
considers the analyst's test method to be satisfactory for a particular 
source, the Administrator may waive the use of this protocol or may 
specify a less rigorous validation procedure. A list of validated 
methods may be obtained by contacting the Emission Measurement Technical 
Information Center (EMTIC), Mail Drop 19, U.S. Environmental Protection 
Agency, Research Triangle Park, NC 27711, (919) 541-0200. Procedures for 
obtaining a waiver are in Section 12.0.
    1.1.2 This method includes optional procedures that may be used to 
expand the applicability of the proposed method. Section 7.0 involves 
ruggedness testing (Laboratory Evaluation), which demonstrates the 
sensitivity of the method to various parameters. Section 8.0 involves a 
procedure for including sample stability in bias and precision for 
assessing sample recovery and analysis times; Section 9.0 involves a 
procedure for the determination of the practical limit of quantitation 
for determining the lower limit of the method. These optional procedures 
are required for the waiver consideration outlined in Section 12.0.
    1.2 Principle. The purpose of these procedures is to determine bias 
and precision of a test method at the level of the applicable standard. 
The procedures involve (a) introducing known concentrations of an 
analyte or comparing the test method against a validated test method to 
determine the method's bias and (b) collecting multiple or collocated 
simultaneous samples to determine the method's precision.
    1.2.1 Bias. Bias is established by comparing the method's results 
against a reference value and may be eliminated by employing a 
correction factor established from the data obtained during the 
validation test. An offset bias may be handled accordingly. Methods that 
have bias correction factors outside 0.7 to 1.3 are unacceptable. 
Validated method to proposed method comparisons, section 6.2, requires a 
more restrictive test of central tendency and a lower correction factor 
allowance of 0.90 to 1.10.
    1.2.2 Precision. At the minimum, paired sampling systems shall be 
used to establish precision. The precision of the method at the level of 
the standard shall not be greater than 50 percent relative standard 
deviation. For a validated method to proposed method equivalency 
comparisons, section 6.2, the analyst must demonstrate that the 
precision of the proposed test method is as precise as the validated 
method for acceptance.

                             2. Definitions

    2.1 Negative bias. Bias resulting when the measured result is less 
than the ``true'' value.
    2.2 Paired sampling system. A sampling system capable of obtaining 
two replicate samples that were collected as closely as possible in 
sampling time and sampling location.
    2.3 Positive bias. Bias resulting when the measured result is 
greater than the ``true'' value.
    2.4 Proposed method. The sampling and analytical methodology 
selected for field validation using the method described herein.
    2.5 Quadruplet sampling system. A sampling system capable of 
obtaining four replicate samples that were collected as closely as 
possible in sampling time and sampling location.
    2.6 Surrogate compound. A compound that serves as a model for the 
types of compounds being analyzed (i.e., similar chemical structure, 
properties, behavior). The model can be distinguished by the method from 
the compounds being analyzed.

                          3. Reference Material

    The reference materials shall be obtained or prepared at the level 
of the standard. Additional runs with higher and lower reference 
material concentrations may be made to expand the applicable range of 
the method, in accordance with the ruggedness test procedures.
    3.1 Exhaust Gas Tests. The analyst shall obtain a known 
concentration of the reference material (i.e., analyte of concern) from 
an independent source such as a specialty gas manufacturer, specialty 
chemical company, or commercial laboratory. A list of vendors may be 
obtained from EMTIC (see Section 1.1.1). The analyst should obtain the 
manufacturer's stability data of the analyte concentration and 
recommendations for recertification.
    3.2 Other Waste Media Tests. The analyst shall obtain pure liquid 
components of the reference materials (i.e., analytes of concern) from 
an independent manufacturer and dilute them in the same type matrix as 
the

[[Page 940]]

source waste. The pure reference materials shall be certified by the 
manufacturer as to purity and shelf life. The accuracy of all diluted 
reference material concentrations shall be verified by comparing their 
response to independently-prepared materials (independently prepared in 
this case means prepared from pure components by a different analyst).
    3.3 Surrogate Reference Materials. The analyst may use surrogate 
compounds, e.g., for highly toxic or reactive organic compounds, 
provided the analyst can demonstrate to the Administrator's satisfaction 
that the surrogate compound behaves as the analyte. A surrogate may be 
an isotope or one that contains a unique element (e.g., chlorine) that 
is not present in the source or a derivation of the toxic or reactive 
compound, if the derivative formation is part of the method's procedure. 
Laboratory experiments or literature data may be used to show behavioral 
acceptability.
    3.4 Isotopically Labeled Materials. Isotope mixtures may contain the 
isotope and the natural analyte. For best results, the isotope labeled 
analyte concentration should be more than five times the natural 
concentration of the analyte.

                    4. EPA Performance Audit Material

    4.1 To assess the method bias independently, the analyst shall use 
(in addition to the reference material) an EPA performance audit 
material, if it is available. The analyst may contact EMTIC (see section 
1.1.1) to receive a list of currently available EPA audit materials. If 
the analyte is listed, the analyst should request the audit material at 
least 30 days before the validation test. If an EPA audit material is 
not available, request documentation from the validation report 
reviewing authority that the audit material is currently not available 
from EPA. Include this documentation with the field validation report.
    4.2 The analyst shall sample and analyze the performance audit 
sample three times according to the instructions provided with the audit 
sample. The analyst shall submit the three results with the field 
validation report. Although no acceptance criteria are set for these 
performance audit results, the analyst and reviewing authority may use 
them to assess the relative error of sample recovery, sample 
preparation, and analytical procedures and then consider the relative 
error in evaluating the measured emissions.

    5. Procedure for Determination of Bias and Precision in the Field

    The analyst shall select one of the sampling approaches below to 
determine the bias and precision of the data. After analyzing the 
samples, the analyst shall calculate the bias and precision according to 
the procedure described in section 6.0. When sampling a stationary 
source, follow the probe placement procedures in section 5.4.
    5.1 Isotopic Spiking. This approach shall be used only for methods 
that require mass spectrometry (MS) analysis. Bias and precision are 
calculated by procedures described in section 6.1.
    5.1.1 Number of Samples and Sampling Runs. Collect a total of 12 
replicate samples by either obtaining six sets of paired samples or 
three sets of quadruplet samples.
    5.1.2 Spiking Procedure. Spike all 12 samples with the reference 
material at the level of the standard. Follow the appropriate spiking 
procedures listed below for the applicable waste medium.
    5.1.2.1 Exhaust Gas Testing. The spike shall be introduced as close 
to the tip of the sampling probe as possible.
    5.1.2.1.1 Gaseous Reference Material with Sorbent or Impinger 
Sampling Trains. Sample the reference material (in the laboratory or in 
the field) at a concentration which is close to the allowable 
concentration standard for the time required by the method, and then 
sample the gas stream for an equal amount of time. The time for sampling 
both the reference material and gas stream should be equal; however, the 
time should be adjusted to avoid sorbent breakthrough.
    5.1.2.1.2 Gaseous Reference Material with Sample Container (Bag or 
Canister). Spike the sample containers after completion of each test run 
with an amount equal to the allowable concentration standard of the 
emission point. The final concentration of the reference material shall 
approximate the level of the emission concentration in the stack. The 
volume amount of reference material shall be less than 10 percent of the 
sample volume.
    5.1.2.1.3 Liquid and Solid Reference Material with Sorbent or 
Impinger Trains. Spike the trains with an amount equal to the allowable 
concentration standard before sampling the stack gas. The spiking should 
be done in the field; however, it may be done in the laboratory.
    5.1.2.1.4 Liquid and Solid Reference Material with Sample Container 
(Bag or Canister). Spike the containers at the completion of each test 
run with an amount equal to the level of the emission standard.
    5.1.2.2 Other Waste Media. Spike the 12 replicate samples with the 
reference material either before or directly after sampling in the 
field.
    5.2 Comparison Against a Validated Test Method. Bias and precision 
are calculated using the procedures described in section 6.2. This 
approach shall be used when a validated method is available and an 
alternative method is being proposed.
    5.2.1 Number of Samples and Sampling Runs. Collect nine sets of 
replicate samples using a

[[Page 941]]

paired sampling system (a total of 18 samples) or four sets of replicate 
samples using a quadruplet sampling system (a total of 16 samples). In 
each sample set, the validated test method shall be used to collect and 
analyze half of the samples.
    5.2.2 Performance Audit Exception. Conduct the performance audit as 
required in section 4.0 for the validated test method. Conducting a 
performance audit on the test method being evaluated is recommended.
    5.3 Analyte Spiking. This approach shall be used when sections 5.1 
and 5.2 are not applicable. Bias and precision are calculated using the 
procedures described in Section 6.3.
    5.3.1 Number of Samples and Sampling Runs. Collect a total of 24 
samples using the quadruplet sampling system (a total of 6 sets of 
replicate samples).
    5.3.2 In each quadruplet set, spike half of the samples (two out of 
the four) with the reference material according to the applicable 
procedure in section 5.1.2.1 or 5.1.2.2.
    5.4 Probe Placement and Arrangement for Stationary Source Stack or 
Duct Sampling. The probes shall be placed in the same horizontal plane. 
For paired sample probes the arrangement should be that the probe tip is 
2.5 cm from the outside edge of the other with a pitot tube on the 
outside of each probe. Other paired arrangements for the pitot tube may 
be acceptable. For quadruplet sampling probes, the tips should be in a 
6.0 cm x 6.0 cm square area measured from the center line of the opening 
of the probe tip with a single pitot tube in the center or two pitot 
tubes with their location on either side of the probe tip configuration. 
An alternative arrangement should be proposed whenever the cross-
sectional area of the probe tip configuration is approximately 5 percent 
of the stack or duct cross-sectional area.

                             6. Calculations

    Data resulting from the procedures specified in section 5.0 shall be 
treated as follows to determine bias, correction factors, relative 
standard deviations, precision, and data acceptance.
    6.1 Isotopic Spiking. Analyze the data for isotopic spiking tests as 
outlined in sections 6.1.1 through 6.1.6.
    6.1.1 Calculate the numerical value of the bias using the results 
from the analysis of the isotopically spiked field samples and the 
calculated value of the isotopically labeled spike:

B=CS-Sm Eq. 301=1

where:

B=Bias at the spike level.
Sm=Mean of the measured values of the isotopically spiked 
          samples.
CS=Calculated value of the isotopically labeled spike.
    6.1.2 Calculate the standard deviation of the Si values 
as follows:
[GRAPHIC] [TIFF OMITTED] TC01MY92.048


Eq. 301-2

where:

S i=Measured value of the isotopically labeled analyte in the 
          ith field sample,
n=Number of isotopically spiked samples, 12.
    6.1.3. Calculate the standard deviation of the mean (SDM) as 
follows:
[GRAPHIC] [TIFF OMITTED] TC01MY92.049


Eq. 301-3
    6.1.4 Test the bias for statistical significance by calculating the 
t-statistic,
[GRAPHIC] [TIFF OMITTED] TC01MY92.050

Eq. 301-4

and compare it with the critical value of the two-sided t-distribution 
at the 95-percent confidence level and n-1 degrees of freedom. This 
critical value is 2.201 for the eleven degrees of freedom when the 
procedure specified in section 5.1.2 is followed. If the calculated t-
value is greater than the critical value the bias is statistically 
significant and the analyst should proceed to evaluate the correction 
factor.
    6.1.5 Calculation of a Correction Factor. If the t-test does not 
show that the bias is statistically significant, use all analytical 
results without correction and proceed to the precision evaluation. If 
the method's bias is statistically significant, calculate the correction 
factor, CF, using the following equation:
[GRAPHIC] [TIFF OMITTED] TC01MY92.051

Eq. 301-5
If the CF is outside the range of 0.70 to 1.30, the data and method are 
considered unacceptable. For correction factors within the range, 
multiply all analytical results by the CF to obtain the final values.
    6.1.6 Calculation of the Relative Standard Deviation (Precision). 
Calculate the relative standard deviation as follows:
[GRAPHIC] [TIFF OMITTED] TC01MY92.052

Eq. 301-6

[[Page 942]]

where Sm is the measured mean of the isotopically labeled 
spiked samples.
    6.2 Comparison with Validated Method. Analyze the data for 
comparison with a validated method as outlined in sections 6.2.1 or 
6.2.2, as appropriate. Conduct these procedures in order to determine if 
a proposed method produces results equivalent to a validated method. 
Make all necessary bias corrections for the validated method, as 
appropriate. If the proposed method fails either test, the method 
results are unacceptable, and conclude that the proposed method is not 
as precise or accurate as the validated method. For highly variable 
sources, additional precision checks may be necessary. The analyst 
should consult with the Administrator if a highly variable source is 
suspected.
    6.2.1 Paired Sampling Systems.
    6.2.1.1. Precision. Determine the acceptance of the proposed 
method's variance with respect to the variability of the validated 
method results. If a significant difference is determined, the proposed 
method and the results are rejected. Proposed methods demonstrating F-
values equal to or less than the critical value have acceptable 
precision.
    6.2.1.2 Calculate the variance of the proposed method, 
Sp2, and the variance of the validated method, 
Sv2, using the following equation:

S(porv)2=SD2 Eq. 301-7

where:

SDv=Standard deviation provided with the validated method,
SDp=Standard deviation of the proposed method calculated 
          using Equation 301-9a.

    6.2.1.3 The F-test. Determine if the variance of the proposed method 
is significantly different from that of the validated method by 
calculating the F-value using the following equation:
[GRAPHIC] [TIFF OMITTED] TC01MY92.053

Eq. 301-8
    Compare the experimental F value with the critical value of F. The 
critical value is 1.0 when the procedure specified in section 5.2.1 for 
paired trains is followed. If the calculated F is greater than the 
critical value, the difference in precision is significant and the data 
and proposed method are unacceptable.
    6.2.1.4 Bias Analysis. Test the bias for statistical significance by 
calculating the t-statistic and determine if the mean of the differences 
between the proposed method and the validated method is significant at 
the 80-percent confidence level. This procedure requires the standard 
deviation of the validated method, SDv, to be known. Employ 
the value furnished with the method. If the standard deviation of the 
validated method is not available, the paired replicate sampling 
procedure may not be used. Determine the mean of the paired sample 
differences, dm, and the standard deviation, SDd, 
of the differences, d1's, using Equation 301-2 where: 
di replaces Si, dm replaces 
Sm. Calculate the standard deviation of the proposed method, 
SDp, as follows:

SDp=SDd-SDv Eq. 301-9a

(If SDvSDd, let SD=SDd/
          1.414).

    Calculate the value of the t-statistic using the following equation:
    [GRAPHIC] [TIFF OMITTED] TC01MY92.054
    
Eq. 301-9

where n is the total number of paired samples. For the procedure in 
section 5.2.1, n equals nine. Compare the calculated t-statistic with 
the corresponding value from the table of the t-statistic. When nine 
runs are conducted, as specified in section 5.2.1, the critical value of 
the t-statistic is 1.397 for eight degrees of freedom. If the calculated 
t-value is greater than the critical value the bias is statistically 
significant and the analyst should proceed to evaluate the correction 
factor.
    6.2.1.5 Calculation of a Correction Factor. If the statistical test 
cited above does not show a significant bias with respect to the 
reference method, assume that the proposed method is unbiased and use 
all analytical results without correction. If the method's bias is 
statistically significant, calculate the correction factor, CF, as 
follows:
[GRAPHIC] [TIFF OMITTED] TC01MY92.055

Eq. 301-10

where Vm is the mean of the validated method's values.
    Multiply all analytical results by CF to obtain the final values. 
The method results, and the method, are unacceptable if the correction 
factor is outside the range of 0.9 to 1.10.
    6.2.2 Quadruplet Replicate Sampling Systems.
    6.2.2.1 Precision. Determine the acceptance of the proposed method's 
variance with respect to the variability of the validated method 
results. If a significant difference is determined the proposed method 
and the results are rejected.
    6.2.2.2 Calculate the variance of the proposed method, 
Sp2, using the following equation:

[[Page 943]]

[GRAPHIC] [TIFF OMITTED] TC01MY92.056

Eq. 301-11

where the di's are the differences between the validated 
method values and the proposed method values.

    6.2.2.3 The F-test. Determine if the variance of the proposed method 
is more variable than that of the validated method by calculating the F-
value using Equation 301-8. Compare the experimental F value with the 
critical value of F. The critical value is 1.0 when the procedure 
specified in section 5.2.2 for quadruplet trains is followed. The 
calculated F should be less than or equal to the critical value. If the 
difference in precision is significant the results and the proposed 
method are unacceptable.
    6.2.2.4 Bias Analysis. Test the bias for statistical significance at 
the 80 percent confidence level by calculating the t-statistic. 
Determine the bias (mean of the differences between the proposed method 
and the validated method, dm) and the standard deviation, 
SDd, of the differences. Calculate the standard deviation of 
the differences, SDd, using Equation 301-2 and substituting 
di for Si. The following equation is used to 
calculate di:
[GRAPHIC] [TIFF OMITTED] TC01MY92.057

Eq. 301-12

and: V1i=First measured value of the validated method in the 
          ith test sample.
P1i=First measured value of the proposed method in the ith 
          test sample.

    Calculate the t-statistic using Equation 301-9 where n is the total 
number of test sample differences (di). For the procedure in 
section 5.2.2, n equals four. Compare the calculated t-statistic with 
the corresponding value from the table of the t-statistic and determine 
if the mean is significant at the 80-percent confidence level. When four 
runs are conducted, as specified in section 5.2.2, the critical value of 
the t-statistic is 1.638 for three degrees of freedom. If the calculated 
t-value is greater than the critical value the bias is statistically 
significant and the analyst should proceed to evaluate the correction 
factor.
    6.2.2.5 Correction Factor Calculation. If the method's bias is 
statistically significant, calculate the correction factor, CF, using 
Equation 301-10. Multiply all analytical results by CF to obtain the 
final values. The method results, and the method, are unacceptable if 
the correction factor is outside the range of 0.9 to 1.10.
    6.3 Analyte Spiking. Analyze the data for analyte spike testing as 
outlined in Sections 6.3.1 through 6.3.3.
    6.3.1 Precision.
    6.3.1.1 Spiked Samples. Calculate the difference, di, 
between the pairs of the spiked proposed method measurements for each 
replicate sample set. Determine the standard deviation (SDs) 
of the spiked values using the following equation:
[GRAPHIC] [TIFF OMITTED] TC01MY92.058

Eq. 301-13

where: n = Number of runs.
    Calculate the relative standard deviation of the proposed spiked 
method using Equation 301-6 where Sm is the measured mean of 
the analyte spiked samples. The proposed method is unacceptable if the 
RSD is greater than 50 percent.
    6.3.1.2 Unspiked Samples. Calculate the standard deviation of the 
unspiked values using Equation 301-13 and the relative standard 
deviation of the proposed unspiked method using Equation 301-6 where 
Sm is the measured mean of the analyte spiked samples. The 
RSD must be less than 50 percent.
    6.3.2 Bias. Calculate the numerical value of the bias using the 
results from the analysis of the spiked field samples, the unspiked 
field samples, and the calculated value of the spike:

B=Sm-Mm-CS
Eq. 301-14

where: B = Bias at the spike level.
Sm = Mean of the spiked samples.
Mm = Mean of the unspiked samples.
CS = Calculated value of the spiked level.
    6.3.2.1 Calculate the standard deviation of the mean using the 
following equation where SDs and SDu are the 
standard deviations of the spiked and unspiked sample values 
respectively as calculated using Equation 301-13.
[GRAPHIC] [TIFF OMITTED] TC01MY92.059

Eq. 301-15

    6.3.2.2 Test the bias for statistical significance by calculating 
the t-statistic using Equation 301-4 and comparing it with the critical 
value of the two-sided t-distribution at the 95-percent confidence level 
and n-1 degrees of freedom. This critical value is 2.201 for the eleven 
degrees of freedom.
    6.3.3 Calculation of a Correction Factor. If the t-test shows that 
the bias is not statistically significant, use all analytical results 
without correction. If the method's bias is statistically significant, 
calculate the correction factor using Equation 301-5. Multiply

[[Page 944]]

all analytical results by CF to obtain the final values.

                    7. Ruggedness Testing (Optional)

    7.1 Laboratory Evaluation.
    7.1.1 Ruggedness testing is a useful and cost-effective laboratory 
study to determine the sensitivity of a method to certain parameters 
such as sample collection rate, interferant concentration, collecting 
medium temperature, or sample recovery temperature. This Section 
generally discusses the principle of the ruggedness test. A more 
detailed description is presented in citation 10 of Section 13.0.
    7.1.2 In a ruggedness test, several variables are changed 
simultaneously rather than one variable at a time. This reduces the 
number of experiments required to evaluate the effect of a variable. For 
example, the effect of seven variables can be determined in eight 
experiments rather than 128 (W.J. Youden, Statistical Manual of the 
Association of Official Analytical Chemists, Association of Official 
Analytical Chemists, Washington, DC, 1975, pp. 33-36).
    7.1.3 Data from ruggedness tests are helpful in extending the 
applicability of a test method to different source concentrations or 
source categories.

   8. Procedure for Including Sample Stability in Bias and Precision 
                               Evaluations

    8.1 Sample Stability.
    8.1.1 The test method being evaluated must include procedures for 
sample storage and the time within which the collected samples shall be 
analyzed.
    8.1.2 This section identifies the procedures for including the 
effect of storage time in bias and precision evaluations. The evaluation 
may be deleted if the test method specifies a time for sample storage.
    8.2 Stability Test Design. The following procedures shall be 
conducted to identify the effect of storage times on analyte samples. 
Store the samples according to the procedure specified in the test 
method. When using the analyte spiking procedures (section 5.3), the 
study should include equal numbers of spiked and unspiked samples.
    8.2.1 Stack Emission Testing.
    8.2.1.1 For sample container (bag or canister) and impinger sampling 
systems, sections 5.1 and 5.3, analyze six of the samples at the minimum 
storage time. Then analyze the same six samples at the maximum storage 
time.
    8.2.1.2 For sorbent and impinger sampling systems, sections 5.1 and 
5.3, that require extraction or digestion, extract or digest six of the 
samples at the minimum storage time and extract or digest six other 
samples at the maximum storage time. Analyze an aliquot of the first six 
extracts (digestates) at both the minimum and maximum storage times. 
This will provide some freedom to analyze extract storage impacts.
    8.2.1.3 For sorbent sampling systems, sections 5.1 and 5.3, that 
require thermal desorption, analyze six samples at the minimum storage 
time. Analyze another set of six samples at the maximum storage time.
    8.2.1.4 For systems set up in accordance with section 5.2, the 
number of samples analyzed at the minimum and maximum storage times 
shall be half those collected (8 or 9). The procedures for samples 
requiring extraction or digestion should parallel those in section 
8.2.1.
    8.2.2 Other Waste Media Testing. Analyze half of the replicate 
samples at the minimum storage time and the other half at the maximum 
storage time in order to identify the effect of storage times on analyte 
samples.

   9. Procedure for Determination of Practical Limit of Quantitation 
                               (Optional)

    9.1 Practical Limit of Quantitation.
    9.1.1 The practical limit of quantitation (PLQ) is the lowest level 
above which quantitative results may be obtained with an acceptable 
degree of confidence. For this protocol, the PLQ is defined as 10 times 
the standard deviation, so, at the blank level. This PLQ 
corresponds to an uncertainty of [plusmn]30 percent at the 99-percent 
confidence level.
    9.1.2 The PLQ will be used to establish the lower limit of the test 
method.
    9.2 Procedure I for Estimating so. This procedure is 
acceptable if the estimated PLQ is no more than twice the calculated 
PLQ. If the PLQ is greater than twice the calculated PLQ use Procedure 
II.
    9.2.1 Estimate the PLQ and prepare a test standard at this level. 
The test standard could consist of a dilution of the reference material 
described in section 3.0.
    9.2.2 Using the normal sampling and analytical procedures for the 
method, sample and analyze this standard at least seven times in the 
laboratory.
    9.2.3 Calculate the standard deviation, so, of the 
measured values.
    9.2.4 Calculate the PLQ as 10 times so.
    9.3 Procedure II for Estimating so. This procedure is to 
be used if the estimated PLQ is more than twice the calculated PLQ.
    9.3.1 Prepare two additional standards at concentration levels lower 
than the standard used in Procedure I.
    9.3.2 Sample and analyze each of these standards at least seven 
times.
    9.3.3 Calculate the standard deviation for each concentration level.
    9.3.4 Plot the standard deviations of the three test standards as a 
function of the standard concentrations.

[[Page 945]]

    9.3.5 Draw a best-fit straight line through the data points and 
extrapolate to zero concentration. The standard deviation at zero 
concentration is S0.
    9.3.6 Calculate the PLQ as 10 times S0.

                10.0 Field Validation Report Requirements

    The field validation report shall include a discussion of the 
regulatory objectives for the testing which describe the reasons for the 
test, applicable emission limits, and a description of the source. In 
addition, validation results shall include:
    10.1 Summary of the results and calculations shown in section 6.0.
    10.2 Reference material certification and value(s).
    10.3 Performance audit results or letter from the reviewing 
authority stating the audit material is currently not available.
    10.4 Laboratory demonstration of the quality of the spiking system.
    10.5 Discussion of laboratory evaluations.
    10.6 Discussion of field sampling.
    10.7 Discussion of sample preparations and analysis.
    10.8 Storage times of samples (and extracts, if applicable).
    10.9 Reasons for eliminating any results.

                          11. Followup Testing

    The correction factor calculated in section 6.0 shall be used to 
adjust the sample concentrations in all followup tests conducted at the 
same source. These tests shall consist of at least three replicate 
samples, and the average shall be used to determine the pollutant 
concentration. The number of samples to be collected and analyzed shall 
be as follows, depending on the validated method precision level:
    11.1 Validated relative standard deviation (RSD) [le] [plusmn]15 
Percent. Three replicate samples.
    11.2 Validated RSD [le] [plusmn]30 Percent. Six replicate samples.
    11.3 Validated RSD [le] [plusmn]50 Percent. Nine replicate samples.
    11.4 Equivalent method. Three replicate samples.

                  12. Procedure for Obtaining a Waiver

    12.1 Waivers. These procedures may be waived or a less rigorous 
protocol may be granted for site-specific applications. The following 
are three example situations for which a waiver may be considered.
    12.1.1 ``Similar'' Sources. If the test method has been validated 
previously at a ``similar'' source, the procedures may be waived 
provided the requester can demonstrate to the satisfaction of the 
Administrator that the sources are ``similar.'' The methods's 
applicability to the ``similar'' source may be demonstrated by 
conducting a ruggedness test as described in section 6.0.
    12.1.2 ``Documented'' Methods. In some cases, bias and precision may 
have been documented through laboratory tests or protocols different 
from this method. If the analyst can demonstrate to the satisfaction of 
the Administrator that the bias and precision apply to a particular 
application, the Administrator may waive these procedures or parts of 
the procedures.
    12.1.3 ``Conditional'' Test Methods. When the method has been 
demonstrated to be valid at several sources, the analyst may seek a 
``conditional'' method designation from the Administrator. 
``Conditional'' method status provides an automatic waiver from the 
procedures provided the test method is used within the stated 
applicability.
    12.2 Application for Waiver. In general, the requester shall provide 
a thorough description of the test method, the intended application, and 
results of any validation or other supporting documents. Because of the 
many potential situations in which the Administrator may grant a waiver, 
it is neither possible nor desirable to prescribe the exact criteria for 
a waiver. At a minimum, the requester is responsible for providing the 
following.
    12.2.1 A clearly written test method, preferably in the format of 40 
CFR part 60, appendix A Test Methods. The method must include an 
applicability statement, concentration range, precision, bias 
(accuracy), and time in which samples must be analyzed.
    12.2.2.2 Summaries (see section 10.0) of previous validation tests 
or other supporting documents. If a different procedure from that 
described in this method was used, the requester shall provide 
appropriate documents substantiating (to the satisfaction of the 
Administrator) the bias and precision values.
    12.2.2.3 Results of testing conducted with respect to sections 7.0, 
8.0, and 9.0.
    12.2.3 Discussion of the applicability statement and arguments for 
approval of the waiver. This discussion should address as applicable the 
following: Applicable regulation, emission standards, effluent 
characteristics, and process operations.
    12.3 Requests for Waiver. Each request shall be in writing and 
signed by the analyst. Submit requests to the Director, OAQPS, Technical 
Support Division, U.S. Environmental Protection Agency, Research 
Triangle Park, NC 27711.

Method 303--Determination of Visible Emissions From By-Product Coke Oven 
                                Batteries

    Note: This method is not inclusive with respect to observer 
certification. Some material is incorporated by reference from other 
methods in appendix A to 40 CFR part 60. Therefore, to obtain reliable 
results, persons using this method should have a thorough knowledge of 
Method 9.

                        1.0 Scope and Application

    1.1 Applicability. This method is applicable for the determination 
of visible emissions (VE) from the following by-product coke oven 
battery sources: charging systems during charging; doors, topside port 
lids, and offtake systems on operating coke ovens; and collecting mains. 
This method is also applicable for qualifying observers for visually 
determining the presence of VE.

                          2.0 Summary of Method

    2.1 A certified observer visually determines the VE from coke oven 
battery sources. Certification procedures are presented. This method 
does not require that opacity of emissions be determined or that 
magnitude be differentiated.

                             3.0 Definitions

    3.1 Bench means the platform structure in front of the oven doors.
    3.2 By-product Coke Oven Battery means a source consisting of a 
group of ovens connected by common walls, where coal undergoes 
destructive distillation under positive pressure to produce coke and 
coke oven gas, from which by-products are recovered.
    3.3 Charge or charging period means the period of time that 
commences when coal begins to flow into an oven through a topside port 
and ends when the last charging port is recapped.
    3.4 Charging system means an apparatus used to charge coal to a coke 
oven (e.g., a larry car for wet coal charging systems).
    3.5 Coke oven door means each end enclosure on the push side and the 
coking side of an oven. The chuck, or leveler-bar, door is considered 
part of the push side door. The coke oven door area includes the entire 
area on the vertical face of a coke oven between the bench and the top 
of the battery between two adjacent buck stays.
    3.6 Coke side means the side of a battery from which the coke is 
discharged from ovens at the end of the coking cycle.
    3.7 Collecting main means any apparatus that is connected to one or 
more offtake systems and that provides a passage for conveying gases 
under positive pressure from the by-product coke oven battery to the by-
product recovery system.
    3.8 Consecutive charges means charges observed successively, 
excluding any charge during which the observer's view of the charging 
system or topside ports is obscured.
    3.9 Damper-off means to close off the gas passage between the coke 
oven and the collecting main, with no flow of raw coke oven gas from the 
collecting main into the oven or into the oven's offtake system(s).

[[Page 947]]

    3.10 Decarbonization period means the period of time for combusting 
oven carbon that commences when the oven lids are removed from an empty 
oven or when standpipe caps of an oven are opened. The period ends with 
the initiation of the next charging period for that oven.
    3.11 Larry car means an apparatus used to charge coal to a coke oven 
with a wet coal charging system.
    3.12 Log average means logarithmic average as calculated in Section 
12.4.

stationary and provides a passage for gases from an oven to a coke oven 
battery collecting main or to another oven. Offtake system components 
include the standpipe and standpipe caps, goosenecks, stationary jumper 
pipes, mini-standpipes, and standpipe and gooseneck connections.
    3.14 Operating oven means any oven not out of operation for rebuild 
or maintenance work extensive enough to require the oven to be skipped 
in the charging sequence.
    3.15 Oven means a chamber in the coke oven battery in which coal 
undergoes destructive distillation to produce coke.
    3.16 Push side means the side of the battery from which the coke is

(except for corrective lenses) eye, excluding steam or condensing water.

                      4.0 Interferences [Reserved]

                               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 Safety Training. Because coke oven batteries have hazardous 
environments, the training materials and the field training (Section 
10.0) shall cover the precautions required by the company to address 
health and safety hazards. Special emphasis shall be given to the 
Occupational Safety and Health Administration (OSHA) regulations 
pertaining to exposure of coke oven workers (see Reference 3 in Section 
16.0). In general, the regulation requires that special fire-retardant 
clothing and respirators be worn in certain restricted areas of the coke 
oven battery. The OSHA regulation also prohibits certain activities, 
such as chewing gum, smoking, and eating in these areas.

                  6.0 Equipment and Supplies [Reserved]

                  7.0 Reagents and Standards [Reserved]

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

                     9.0 Quality Control [Reserved]

                  10.0 Calibration and Standardization

    Observer certification and training requirements are as follows:
    10.1 Certification Procedures. This method requires only the 
determination of whether VE occur and does not require the determination 
of opacity levels; therefore, observer certification according to Method 
9 in appendix A to part 60 of this chapter is not required to obtain 
certification under this method. However, in order to receive Method 303 
observer certification, the first-time observer (trainee) shall have 
attended the lecture portion of the Method 9 certification course. In 
addition, the trainee shall successfully complete the Method 303 
training course, satisfy the field observation requirement, and 
demonstrate adequate performance and sufficient knowledge of Method 303. 
The Method 303 training course shall be conducted by or under the 
sanction of the EPA and shall consist of classroom instruction and field 
observations, and a proficiency test.
    10.1.1 The classroom instruction shall familiarize the trainees with 
Method 303 through lecture, written training materials, and a Method 303 
demonstration video. A successful completion of the classroom portion of 
the Method 303 training course shall be demonstrated by a perfect score 
on a written test. If the trainee fails to answer all of the questions 
correctly, the trainee may review the appropriate portion of the 
training materials and retake the test.

[[Page 948]]

    10.1.2 The field observations shall be a minimum of 12 hours and 
shall be completed before attending the Method 303 certification course. 
Trainees shall observe the operation of a coke oven battery as it 
pertains to Method 303, including topside operations, and shall also 
practice conducting Method 303 or similar methods. During the field 
observations, trainees unfamiliar with coke battery operations shall 
receive instruction from an experienced coke oven observer familiar with 
Method 303 or similar methods and with the operation of coke batteries. 
The trainee must verify completion of at least 12 hours of field 
observation prior to attending the Method 303 certification course.
    10.1.3 All trainees must demonstrate proficiency in the application 
of Method 303 to a panel of three certified Method 303 observers, 
including an ability to differentiate coke oven emissions from 
condensing water vapor and smoldering coal. Each panel member shall have 
at least 120 days experience in reading visible emissions from coke 
ovens. The visible emissions inspections that will satisfy the 
experience requirement must be inspections of coke oven battery fugitive 
emissions from the emission points subject to emission standards under 
subpart L of this part (i.e., coke oven doors, topside port lids, 
offtake system(s), and charging operations), using either Method 303 or 
predecessor State or local test methods. A ``day's experience'' for a 
particular inspection is a day on which one complete inspection was 
performed for that emission point under Method 303 or a predecessor 
State or local method. A ``day's experience'' does not mean 8 or 10 
hours performing inspections, or any particular time expressed in 
minutes or hours that may have been spent performing them. Thus, it 
would be possible for an individual to qualify as a Method 303 panel 
member for some emission points, but not others (e.g., an individual 
might satisfy the experience requirement for coke oven doors, but not 
topside port lids). Until November 15, 1994, the EPA may waive the 
certification requirement (but not the experience requirement) for panel 
members. The composition of the panel shall be approved by the EPA. The 
panel shall observe the trainee in a series of training runs and a 
series of certification runs. There shall be a minimum of 1 training run 
for doors, topside port lids, and offtake systems, and a minimum of 5 
training runs (i.e., 5 charges) for charging. During training runs, the 
panel can advise the trainee on proper procedures. There shall be a 
minimum of 3 certification runs for doors, topside port lids, and 
offtake systems, and a minimum of 15 certification runs for charging 
(i.e., 15 charges). The certifications runs shall be unassisted. 
Following the certification test runs, the panel shall approve or 
disapprove certification based on the trainee's performance during the 
certification runs. To obtain certification, the trainee shall 
demonstrate to the satisfaction of the panel a high degree of 
proficiency in performing Method 303. To aid in evaluating the trainee's 
performance, a checklist, provided by the EPA, will be used by the panel 
members.
    10.2 Observer Certification/Recertification. The coke oven observer 
certification is valid for 1 year from date of issue. The observer shall 
recertify annually by viewing the training video and answering all of 
the questions on the certification test correctly. Every 3 years, an 
observer shall be required to pass the proficiency test in Section 
10.1.3 in order to be certified.
    10.3 The EPA (or applicable enforcement agency) shall maintain 
records reflecting a certified observer's successful completion of the 
proficiency test, which shall include the completed proficiency test 
checklists for the certification runs.
    10.4 An owner or operator of a coke oven battery subject to subpart 
L of this part may observe a training and certification program under 
this section.

                             11.0 Procedure

    11.1 Procedure for Determining VE from Charging Systems During 
Charging.
    11.1.1 Number of Oven Charges. Refer to Sec. 63.309(c)(1) of this 
part for the number of oven charges to observe. The observer shall 
observe consecutive charges. Charges that are nonconsecutive can only be 
observed when necessary to replace observations terminated prior to the 
completion of a charge because of visual interferences. (See Section 
11.1.5).
    11.1.2 Data Records. Record all the information requested at the top 
of the charging system inspection sheet (Figure 303-1). For each charge, 
record the identification number of the oven being charged, the 
approximate beginning time of the charge, and the identification of the 
larry car used for the charge.
    11.1.3 Observer Position. Stand in an area or move to positions on 
the topside of the coke oven battery with an unobstructed view of the 
entire charging system. For wet coal charging systems or non-pipeline 
coal charging systems, the observer should have an unobstructed view of 
the emission points of the charging system, including larry car hoppers, 
drop sleeves, and the topside ports of the oven being charged. Some 
charging systems are configured so that all emission points can only be 
seen from a distance of five ovens. For other batteries, distances of 8 
to 12 ovens are adequate.
    11.1.4 Observation. The charging period begins when coal begins to 
flow into the oven and ends when the last charging port is recapped. 
During the charging period, observe all of the potential sources of VE 
from the

[[Page 949]]

entire charging system. For wet coal charging systems or non-pipeline 
coal charging systems, sources of VE typically include the larry car 
hoppers, drop sleeves, slide gates, and topside ports on the oven being 
charged. Any VE from an open standpipe cap on the oven being charged is 
included as charging VE.
    11.1.4.1 Using an accumulative-type stopwatch with unit divisions of 
at least 0.5 seconds, determine the total time VE are observed as 
follows. Upon observing any VE emerging from any part of the charging 
system, start the stopwatch. Stop the watch when VE are no longer 
observed emerging, and restart the watch when VE reemerges.
    11.1.4.2 When VE occur simultaneously from several points during a 
charge, consider the sources as one. Time overlapping VE as continuous 
VE. Time single puffs of VE only for the time it takes for the puff to 
emerge from the charging system. Continue to time VE in this manner for 
the entire charging period. Record the accumulated time to the nearest 
0.5 second under ``Visible emissions, seconds'' on Figure 303-1.
    11.1.5 Visual Interference. If fugitive VE from other sources at the 
coke oven battery site (e.g., door leaks or condensing water vapor from 
the coke oven wharf) prevent a clear view of the charging system during 
a charge, stop the stopwatch and make an appropriate notation under 
``Comments'' on Figure 303-1. Label the observation an observation of an 
incomplete charge, and observe another charge to fulfill the 
requirements of Section 11.1.1.
    11.1.6 VE Exemptions. Do not time the following VE:
    11.1.6.1 The VE from burning or smoldering coal spilled on top of 
the oven, topside port lid, or larry car surfaces;
    Note: The VE from smoldering coal are generally white or gray. These 
VE generally have a plume of less than 1 meter long. If the observer 
cannot safely and with reasonable confidence determine that VE are from 
charging, do not count them as charging emissions.
    11.1.6.2 The VE from the coke oven doors or from the leveler bar; or
    11.1.6.3 The VE that drift from the top of a larry car hopper if the 
emissions had already been timed as VE from the drop sleeve.
    Note: When the slide gate on a larry car hopper closes after the 
coal has been added to the oven, the seal may not be airtight. On 
occasions, a puff of smoke observed at the drop sleeves is forced past 
the slide gate up into the larry car hopper and may drift from the top; 
time these VE either at the drop sleeves or the hopper. If the larry car 
hopper does not have a slide gate or the slide gate is left open or 
partially closed, VE may quickly pass through the larry car hopper 
without being observed at the drop sleeves and will appear as a strong 
surge of smoke; time these as charging VE.
    11.1.7 Total Time Record. Record the total time that VE were 
observed for each charging operation in the appropriate column on the 
charging system inspection sheet.
    11.1.8 Determination of Validity of a Set of Observations. Five 
charging observations (runs) obtained in accordance with this method 
shall be considered a valid set of observations for that day. No 
observation of an incomplete charge shall be included in a daily set of 
observations that is lower than the lowest reading for a complete 
charge. If both complete and incomplete charges have been observed, the 
daily set of observations shall include the five highest values 
observed. Four or three charging observations (runs) obtained in 
accordance with this method shall be considered a valid set of charging 
observations only where it is not possible to obtain five charging 
observations, because visual interferences (see Section 11.1.5) or 
inclement weather prevent a clear view of the charging system during 
charging. However, observations from three or four charges that satisfy 
these requirements shall not be considered a valid set of charging 
observations if use of such set of observations in a calculation under 
Section 12.4 would cause the value of A to be less than 145.
    11.1.9 Log Average. For each day on which a valid daily set of 
observations is obtained, calculate the daily 30-day rolling log average 
of seconds of visible emissions from the charging operation for each 
battery using these data and the 29 previous valid daily sets of 
observations, in accordance with Section 12.4.
    11.2. Procedure for Determining VE from Coke Oven Door Areas. The 
intent of this procedure is to determine VE from coke oven door areas by 
carefully observing the door area from a standard distance while walking 
at a normal pace.
    11.2.1 Number of Runs. Refer to Sec. 63.309(c)(1) of this part for 
the appropriate number of runs.
    11.2.2 Battery Traverse. To conduct a battery traverse, walk the 
length of the battery on the outside of the pusher machine and quench 
car tracks at a steady, normal walking pace, pausing to make appropriate 
entries on the door area inspection sheet (Figure 303-2). A single test 
run consists of two timed traverses, one for the coke side and one for 
the push side. The walking pace shall be such that the duration of the 
traverse does not exceed an average of 4 seconds per oven door, 
excluding time spent moving around stationary obstructions or waiting 
for other obstructions to move from positions blocking the view of a 
series of doors. Extra time is allowed for each leak (a maximum of 10 
additional seconds for each leaking door) for the observer to make the 
proper

[[Page 950]]

notation. A walking pace of 3 seconds per oven door has been found to be 
typical. Record the actual traverse time with a stopwatch.
    11.2.2.1 Include in the traverse time only the time spent observing 
the doors and recording door leaks. To measure actual traverse time, use 
an accumulative-type stopwatch with unit divisions of 0.5 seconds or 
less. Exclude interruptions to the traverse and time required for the 
observer to move to positions where the view of the battery is 
unobstructed, or for obstructions, such as the door machine, to move 
from positions blocking the view of a series of doors.
    11.2.2.2 Various situations may arise that will prevent the observer 
from viewing a door or a series of doors. Prior to the door inspection, 
the owner or operator may elect to temporarily suspend charging 
operations for the duration of the inspection, so that all of the doors 
can be viewed by the observer. The observer has two options for dealing 
with obstructions to view: (a) Stop the stopwatch and wait for the 
equipment to move or the fugitive emissions to dissipate before 
completing the traverse; or (b) stop the stopwatch, skip the affected 
ovens, and move to an unobstructed position to continue the traverse. 
Restart the stopwatch and continue the traverse. After the completion of 
the traverse, if the equipment has moved or the fugitive emissions have 
dissipated, inspect the affected doors. If the equipment is still 
preventing the observer from viewing the doors, then the affected doors 
may be counted as not observed. If option (b) is used because of doors 
blocked by machines during charging operations, then, of the affected 
doors, exclude the door from the most recently charged oven from the 
inspection. Record the oven numbers and make an appropriate notation 
under ``Comments'' on the door area inspection sheet (Figure 303-2).
    11.2.2.3 When batteries have sheds to control emissions, conduct the 
inspection from outside the shed unless the doors cannot be adequately 
viewed. In this case, conduct the inspection from the bench. Be aware of 
special safety considerations pertinent to walking on the bench and 
follow the instructions of company personnel on the required equipment 
and procedures. If possible, conduct the bench traverse whenever the 
bench is clear of the door machine and hot coke guide.
    11.2.3 Observations. Record all the information requested at the top 
of the door area inspection sheet (Figure 303-2), including the number 
of non-operating ovens. Record the clock time at the start of the 
traverse on each side of the battery. Record which side is being 
inspected (i.e., coke side or push side). Other information may be 
recorded at the discretion of the observer, such as the location of the 
leak (e.g., top of the door, chuck door, etc.), the reason for any 
interruption of the traverse, or the position of the sun relative to the 
battery and sky conditions (e.g., overcast, partly sunny, etc.).
    11.2.3.1 Begin the test run by starting the stopwatch and traversing 
either the coke side or the push side of the battery. After completing 
one side, stop the watch. Complete this procedure on the other side. If 
inspecting more than one battery, the observer may view the push sides 
and the coke sides sequentially.
    11.2.3.2 During the traverse, look around the entire perimeter of 
each oven door. The door is considered leaking if VE are detected in the 
coke oven door area. The coke oven door area includes the entire area on 
the vertical face of a coke oven between the bench and the top of the 
battery between two adjacent buck stays (e.g., the oven door, chuck 
door, between the masonry brick, buck stay or jamb, or other sources). 
Record the oven number and make the appropriate notation on the door 
area inspection sheet (Figure 303-2).

    Note: Multiple VE from the same door area (e.g., VE from both the 
chuck door and the push side door) are counted as only one emitting 
door, not as multiple emitting doors.

    11.2.3.3 Do not record the following sources as door area VE:
    11.2.3.3.1 VE from ovens with doors removed. Record the oven number 
and make an appropriate notation under ``Comments;''
    11.2.3.3.2 VE from ovens taken out of service. The owner or operator 
shall notify the observer as to which ovens are out of service. Record 
the oven number and make an appropriate notation under ``Comments;'' or
    11.2.3.3.3 VE from hot coke that has been spilled on the bench as a 
result of pushing.
    11.2.4 Criteria for Acceptance. After completing the run, calculate 
the maximum time allowed to observe the ovens using the equation in 
Section 12.2. If the total traverse time exceeds T, void the run, and 
conduct another run to satisfy the requirements of Sec. 63.309(c)(1) of 
this part.
    11.2.5 Percent Leaking Doors. For each day on which a valid 
observation is obtained, calculate the daily 30-day rolling average for 
each battery using these data and the 29 previous valid daily 
observations, in accordance with Section 12.5.
    11.3 Procedure for Determining VE from Topside Port Lids and Offtake 
Systems.
    11.3.1 Number of Runs. Refer to Sec. 63.309(c)(1) of this part for 
the number of runs to be conducted. Simultaneous runs or separate runs 
for the topside port lids and offtake systems may be conducted.
    11.3.2 Battery Traverse. To conduct a topside traverse of the 
battery, walk the length of the battery at a steady, normal walking 
pace, pausing only to make appropriate entries on the topside inspection 
sheet (Figure 303-3). The walking pace shall not exceed an

[[Page 951]]

average rate of 4 seconds per oven, excluding time spent moving around 
stationary obstructions or waiting for other obstructions to move from 
positions blocking the view. Extra time is allowed for each leak for the 
observer to make the proper notation. A walking pace of 3 seconds per 
oven is typical. Record the actual traverse time with a stopwatch.
    11.3.3 Topside Port Lid Observations. To observe lids of the ovens 
involved in the charging operation, the observer shall wait to view the 
lids until approximately 5 minutes after the completion of the charge. 
Record all the information requested on the topside inspection sheet 
(Figure 303-3). Record the clock time when traverses begin and end. If 
the observer's view is obstructed during the traverse (e.g., steam from 
the coke wharf, larry car, etc.), follow the guidelines given in Section 
11.2.2.2.
    11.3.3.1 To perform a test run, conduct a single traverse on the 
topside of the battery. The observer shall walk near the center of the 
battery but may deviate from this path to avoid safety hazards (such as 
open or closed charging ports, luting buckets, lid removal bars, and 
topside port lids that have been removed) and any other obstacles. Upon 
noting VE from the topside port lid(s) of an oven, record the oven 
number and port number, then resume the traverse. If any oven is 
dampered-off from the collecting main for decarbonization, note this 
under ``Comments'' for that particular oven.

    Note: Count the number of topside ports, not the number of points, 
exhibiting VE, i.e., if a topside port has several points of VE, count 
this as one port exhibiting VE.

    11.3.3.2 Do not count the following as topside port lid VE:
    11.3.3.2.1 VE from between the brickwork and oven lid casing or VE 
from cracks in the oven brickwork. Note these VE under ``Comments;''
    11.3.3.2.2 VE from topside ports involved in a charging operation. 
Record the oven number, and make an appropriate notation (e.g., not 
observed because ports open for charging) under ``Comments;''
    11.3.3.2.3 Topside ports having maintenance work done. Record the 
oven number and make an appropriate notation under ``Comments;'' or
    11.3.3.2.4 Condensing water from wet-sealing material. Ports with 
only visible condensing water from wet-sealing material are counted as 
observed but not as having VE.
    11.3.3.2.5 Visible emissions from the flue inspection ports and 
caps.
    11.3.4 Offtake Systems Observations. To perform a test run, traverse 
the battery as in Section 11.3.3.1. Look ahead and back two to four 
ovens to get a clear view of the entire offtake system for each oven. 
Consider visible emissions from the following points as offtake system 
VE: (a) the flange between the gooseneck and collecting main 
(``saddle''), (b) the junction point of the standpipe and oven 
(``standpipe base''), (c) the other parts of the offtake system (e.g., 
the standpipe cap), and (d) the junction points with ovens and flanges 
of jumper pipes.
    11.3.4.1 Do not stray from the traverse line in order to get a 
``closer look'' at any part of the offtake system unless it is to 
distinguish leaks from interferences from other sources or to avoid 
obstacles.
    11.3.4.2 If the centerline does not provide a clear view of the 
entire offtake system for each oven (e.g., when standpipes are longer 
than 15 feet), the observer may conduct the traverse farther from 
(rather than closer to) the offtake systems.
    11.3.4.3 Upon noting a leak from an offtake system during a 
traverse, record the oven number. Resume the traverse. If the oven is 
dampered-off from the collecting main for decarbonization and VE are 
observed, note this under ``Comments'' for that particular oven.
    11.3.4.4 If any part or parts of an offtake system have VE, count it 
as one emitting offtake system. Each stationary jumper pipe is 
considered a single offtake system.
    11.3.4.5 Do not count standpipe caps open for a decarbonization 
period or standpipes of an oven being charged as source of offtake 
system VE. Record the oven number and write ``Not observed'' and the 
reason (i.e., decarb or charging) under ``Comments.''

    Note: VE from open standpipes of an oven being charged count as 
charging emissions. All VE from closed standpipe caps count as offtake 
leaks.

    11.3.5 Criteria for Acceptance. After completing the run (allow 2 
traverses for batteries with double mains), calculate the maximum time 
allowed to observe the topside port lids and/or offtake systems using 
the equation in Section 12.3. If the total traverse time exceeds T, void 
the run and conduct another run to satisfy the requirements of 
Sec. 63.309(c)(1) of this part.
    11.3.6 In determining the percent leaking topside port lids and 
percent leaking offtake systems, do not include topside port lids or 
offtake systems with VE from the following ovens:
    11.3.6.1 Empty ovens, including ovens undergoing maintenance, which 
are properly dampered off from the main.
    11.3.6.2 Ovens being charged or being pushed.
    11.3.6.3 Up to 3 full ovens that have been dampered off from the 
main prior to pushing.
    11.3.6.4 Up to 3 additional full ovens in the pushing sequence that 
have been dampered off from the main for offtake system cleaning, for 
decarbonization, for safety reasons, or when a charging/pushing schedule 
involves widely separated ovens (e.g., a

[[Page 952]]

Marquard system); or that have been dampered off from the main for 
maintenance near the end of the coking cycle. Examples of reasons that 
ovens are dampered off for safety reasons are to avoid exposing workers 
in areas with insufficient clearance between standpipes and the larry 
car, or in areas where workers could be exposed to flames or hot gases 
from open standpipes, and to avoid the potential for removing a door on 
an oven that is not dampered off from the main.
    11.3.7 Percent Leaking Topside Port Lids and Offtake Systems. For 
each day on which a valid observation is obtained, calculate the daily 
30-day rolling average for each battery using these data and the 29 
previous valid daily observations, in accordance with Sections 12.6 and 
12.7.
    11.4 Procedure for Determining VE from Collecting Mains.
    11.4.1 Traverse. To perform a test run, traverse both the collecting 
main catwalk and the battery topside along the side closest to the 
collecting main. If the battery has a double main, conduct two sets of 
traverses for each run, i.e., one set for each main.
    11.4.2 Data Recording. Upon noting VE from any portion of a 
collection main, identify the source and approximate location of the 
source of VE and record the time under ``Collecting main'' on Figure 
303-3; then resume the traverse.
    11.4.3 Collecting Main Pressure Check. After the completion of the 
door traverse, the topside port lids, and offtake systems, compare the 
collecting main pressure during the inspection to the collecting main 
pressure during the previous 8 to 24 hours. Record the following: (a) 
the pressure during inspection, (b) presence of pressure deviation from 
normal operations, and (c) the explanation for any pressure deviation 
from normal operations, if any, offered by the operators. The owner or 
operator of the coke battery shall maintain the pressure recording 
equipment and conduct the quality assurance/quality control (QA/QC) 
necessary to ensure reliable pressure readings and shall keep the QA/QC 
records for at least 6 months. The observer may periodically check the 
QA/QC records to determine their completeness. The owner or operator 
shall provide access to the records within 1 hour of an observer's 
request.

                   12.0 Data Analysis and Calculations

    12.1 Nomenclature.

follows:
[GRAPHIC] [TIFF OMITTED] TR17OC00.538

    12.5.1 For each test run (one run includes both the coke side and 
the push side traverses), sum the number of doors with door area VE. For 
batteries subject to an approved alternative standard under Sec. 63.305 
of this part, calculate the push side and the coke side PLD separately.

 Method 303A--Determination of Visible Emissions From Nonrecovery Coke 
                             Oven Batteries

    Note: This method does not include all of the specifications 
pertaining to observer certification. Some material is incorporated by 
reference from other methods in this part and in appendix A to 40 CFR 
Part 60. Therefore, to obtain reliable results, persons using this 
method should have a thorough knowledge of Method 9 and Method 303.

                        1.0 Scope and Application

    1.1 Applicability. This method is applicable for the determination 
of visible emissions (VE) from leaking doors at nonrecovery coke oven 
batteries.

                          2.0 Summary of Method

    2.1 A certified observer visually determines the VE from coke oven 
battery sources while walking at a normal pace. This method does not 
require that opacity of emissions be determined or that magnitude be 
differentiated.

                             3.0 Definitions

    3.1 Bench means the platform structure in front of the oven doors.
    3.2 Coke oven door means each end enclosure on the push side and the 
coking side of an oven.
    3.3 Coke side means the side of a battery from which the coke is 
discharged from ovens at the end of the coking cycle.
    3.4 Nonrecovery coke oven battery means a source consisting of a 
group of ovens connected by common walls and operated as a unit, where 
coal undergoes destructive distillation under negative pressure to 
produce coke, and which is designed for the combustion of coke oven gas 
from which by-products are not recovered.
    3.5 Operating oven means any oven not out of operation for rebuild 
or maintenance work extensive enough to require the oven to be skipped 
in the charging sequence.
    3.6 Oven means a chamber in the coke oven battery in which coal 
undergoes destructive distillation to produce coke.
    3.7 Push side means the side of the battery from which the coke is 
pushed from ovens at the end of the coking cycle.
    3.8 Run means the observation of visible emissions from coke oven 
doors in accordance with this method.
    3.9 Shed means an enclosure that covers the side of the coke oven 
battery, captures emissions from pushing operations and from leaking 
coke oven doors on the coke side or push side of the coke oven battery, 
and routes the emissions to a control device or system.
    3.10 Traverse time means accumulated time for a traverse as measured 
by a stopwatch. Traverse time includes time to stop and write down oven 
numbers but excludes time waiting for obstructions of view to clear or 
for time to walk around obstacles.
    3.11 Visible Emissions or VE means any emission seen by the unaided 
(except for corrective lenses) eye, excluding steam or condensing water.

                      4.0 Interferences. [Reserved]

                               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 Safety Training. Because coke oven batteries have hazardous 
environments, the training materials and the field training (Section 
10.0) shall cover the precautions required by the company to address 
health and safety hazards. Special emphasis shall be given to the 
Occupational Safety and Health Administration (OSHA) regulations 
pertaining to exposure of coke oven workers (see Reference 3 in Section 
16.0). In general,

[[Page 958]]

the regulation requires that special fire-retardant clothing and 
respirators be worn in certain restricted areas of the coke oven 
battery. The OSHA regulation also prohibits certain activities, such as 
chewing gum, smoking, and eating in these areas.

                 6.0 Equipment and Supplies. [Reserved]

                  7.0 Reagents and Standards [Reserved]

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

                     9.0 Quality Control. [Reserved]

                  10.0 Calibration and Standardization.

    10.1 Training. This method requires only the determination of 
whether VE occur and does not require the determination of opacity 
levels; therefore, observer certification according to Method 9 in 
Appendix A to Part 60 is not required. However, the first-time observer 
(trainee) shall have attended the lecture portion of the Method 9 
certification course. Furthermore, before conducting any VE 
observations, an observer shall become familiar with nonrecovery coke 
oven battery operations and with this test method by observing for a 
minimum of 4 hours the operation of a nonrecovery coke oven battery in 
the presence of personnel experienced in performing Method 303 
assessments.

                             11.0 Procedure

    The intent of this procedure is to determine VE from coke oven door 
areas by carefully observing the door area while walking at a normal 
pace.
    11.1 Number of Runs. Refer to Sec. 63.309(c)(1) of this part for the 
appropriate number of runs.
    11.2 Battery Traverse. To conduct a battery traverse, walk the 
length of the battery on the outside of the pusher machine and quench 
car tracks at a steady, normal walking pace, pausing to make appropriate 
entries on the door area inspection sheet (Figure 303A-1). The walking 
pace shall be such that the duration of the traverse does not exceed an 
average of 4 seconds per oven door, excluding time spent moving around 
stationary obstructions or waiting for other obstructions to move from 
positions blocking the view of a series of doors. Extra time is allowed 
for each leak (a maximum of 10 additional seconds for each leaking door) 
for the observer to make the proper notation. A walking pace of 3 
seconds per oven door has been found to be typical. Record the actual 
traverse time with a stopwatch. A single test run consists of two timed 
traverses, one for the coke side and one for the push side.
    11.2.1 Various situations may arise that will prevent the observer 
from viewing a door or a series of doors. The observer has two options 
for dealing with obstructions to view: (a) Wait for the equipment to 
move or the fugitive emissions to dissipate before completing the 
traverse; or (b) skip the affected ovens and move to an unobstructed 
position to continue the traverse. Continue the traverse. After the 
completion of the traverse, if the equipment has moved or the fugitive 
emissions have dissipated, complete the traverse by inspecting the 
affected doors. Record the oven numbers and make an appropriate notation 
under ``Comments'' on the door area inspection sheet (Figure 303A-1).

    Note: Extra time incurred for handling obstructions is not counted 
in the traverse time.

    11.2.2 When batteries have sheds to control pushing emissions, 
conduct the inspection from outside the shed, if the shed allows such 
observations, or from the bench. Be aware of special safety 
considerations pertinent to walking on the bench and follow the 
instructions of company personnel on the required equipment and 
operations procedures. If possible, conduct the bench traverse whenever 
the bench is clear of the door machine and hot coke guide.
    11.3 Observations. Record all the information requested at the top 
of the door area inspection sheet (Figure 303A-1), including the number 
of non-operating ovens. Record which side is being inspected, i.e., coke 
side or push side. Other information may be recorded at the discretion 
of the observer, such as the location of the leak (e.g., top of the 
door), the reason for any interruption of the traverse, or the position 
of the sun relative to the battery and sky conditions (e.g., overcast, 
partly sunny, etc.).
    11.3.1 Begin the test run by traversing either the coke side or the 
push side of the battery. After completing one side, traverse the other 
side.
    11.3.2 During the traverse, look around the entire perimeter of each 
oven door. The door is considered leaking if VE are detected in the coke 
oven door area. The coke oven door area includes the entire area on the 
vertical face of a coke oven between the bench and the top of the 
battery and the adjacent doors on both sides. Record the oven number and 
make the appropriate notation on the door area inspection sheet (Figure 
303A-1).
    11.3.3 Do not record the following sources as door area VE:
    11.3.3.1 VE from ovens with doors removed. Record the oven number 
and make an appropriate notation under ``Comments'';
    11.3.3.2 VE from ovens where maintenance work is being conducted. 
Record the oven number and make an appropriate notation under 
``Comments''; or
    11.3.3.3 VE from hot coke that has been spilled on the bench as a 
result of pushing.

Method 304A: Determination of Biodegradation Rates of Organic Compounds 
                              (Vent Option)

                        1.0 Scope and Application

    1.1 Applicability. This method is applicable for the determination 
of biodegradation rates of organic compounds in an activated sludge 
process. The test method is designed to evaluate the ability of an 
aerobic biological reaction system to degrade or destroy specific 
components in waste streams. The method may also be used to determine 
the effects of changes in wastewater composition on operation. The 
biodegradation rates determined by utilizing this method are not 
representative of a full-scale system. The rates measured by this method 
shall be used in conjunction with the procedures listed in appendix C of 
this part to calculate the fraction emitted to the air versus the 
fraction biodegraded.

                          2.0 Summary of Method

    2.1 A self-contained benchtop bioreactor system is assembled in the 
laboratory. A

[[Page 960]]

sample of mixed liquor is added and the waste stream is then fed 
continuously. The benchtop bioreactor is operated under conditions 
nearly identical to the target full-scale activated sludge process. 
Bioreactor temperature, dissolved oxygen concentration, average 
residence time in the reactor, waste composition, biomass concentration, 
and biomass composition of the full-scale process are the parameters 
which are duplicated in the benchtop bioreactor. Biomass shall be 
removed from the target full-scale activated sludge unit and held for no 
more than 4 hours prior to use in the benchtop bioreactor. If 
antifoaming agents are used in the full-scale system, they shall also be 
used in the benchtop bioreactor. The feed flowing into and the effluent 
exiting the benchtop bioreactor are analyzed to determine the 
biodegradation rates of the target compounds. The flow rate of the exit 
vent is used to calculate the concentration of target compounds 
(utilizing Henry's law) in the exit gas stream. If Henry's law constants 
for the compounds of interest are not known, this method cannot be used 
in the determination of the biodegradation rate and Method 304B is the 
suggested method. The choice of analytical methodology for measuring the 
compounds of interest at the inlet and outlet to the benchtop bioreactor 
are left to the discretion of the source, except where validated methods 
are available.

                       3.0 Definitions. [Reserved]

                      4.0 Interferences. [Reserved]

                               5.0 Safety

    5.1 If explosive gases are produced as a byproduct of biodegradation 
and could realistically pose a hazard, closely monitor headspace 
concentration of these gases to ensure laboratory safety. Placement of 
the benchtop bioreactor system inside a laboratory hood is recommended 
regardless of byproducts produced.

                       6.0. Equipment and Supplies

    Note: Figure 304A-1 illustrates a typical laboratory apparatus used 
to measure biodegradation rates. While the following description refers 
to Figure 304A-1, the EPA recognizes that alternative reactor 
configurations, such as alternative reactor shapes and locations of 
probes and the feed inlet, will also meet the intent of this method. 
Ensure that the benchtop bioreactor system is self-contained and 
isolated from the atmosphere (except for the exit vent stream) by leak-
checking fittings, tubing, etc.

    6.1 Benchtop Bioreactor. The biological reaction is conducted in a 
biological oxidation reactor of at least 6 liters capacity. The benchtop 
bioreactor is sealed and equipped with internal probes for controlling 
and monitoring dissolved oxygen and internal temperature. The top of the 
reactor is equipped for aerators, gas flow ports, and instrumentation 
(while ensuring that no leaks to the atmosphere exist around the 
fittings).
    6.2 Aeration gas. Aeration gas is added to the benchtop bioreactor 
through three diffusers, which are glass tubes that extend to the bottom 
fifth of the reactor depth. A pure oxygen pressurized cylinder is 
recommended in order to maintain the specified oxygen concentration. 
Install a blower (e.g., Diaphragm Type, 15 SCFH capacity) to blow the 
aeration gas into the reactor diffusers. Measure the aeration gas flow 
rate with a rotameter (e.g., 0-15 SCFH recommended). The aeration gas 
will rise through the benchtop bioreactor, dissolving oxygen into the 
mixture in the process. The aeration gas must provide sufficient 
agitation to keep the solids in suspension. Provide an exit for the 
aeration gas from the top flange of the benchtop bioreactor through a 
water-cooled (e.g., Allihn-type) vertical condenser. Install the 
condenser through a gas-tight fitting in the benchtop bioreactor 
closure. Install a splitter which directs a portion of the gas to an 
exit vent and the rest of the gas through an air recycle pump back to 
the benchtop bioreactor. Monitor and record the flow rate through the 
exit vent at least 3 times per day throughout the day.
    6.3 Wastewater Feed. Supply the wastewater feed to the benchtop 
bioreactor in a collapsible low-density polyethylene container or 
collapsible liner in a container (e.g., 20 L) equipped with a spigot cap 
(collapsible containers or liners of other material may be required due 
to the permeability of some volatile compounds through polyethylene). 
Obtain the wastewater feed by sampling the wastewater feed in the target 
process. A representative sample of wastewater shall be obtained from 
the piping leading to the aeration tank. This sample may be obtained 
from existing sampling valves at the discharge of the wastewater feed 
pump, or collected from a pipe discharging to the aeration tank, or by 
pumping from a well-mixed equalization tank upstream from the aeration 
tank. Alternatively, wastewater can be pumped continuously to the 
laboratory apparatus from a bleed stream taken from the equalization 
tank of the full-scale treatment system.
    6.3.1 Refrigeration System. Keep the wastewater feed cool by ice or 
by refrigeration to 4 [deg]C. If using a bleed stream from the 
equalization tank, refrigeration is not required if the residence time 
in the bleed stream is less than five minutes.
    6.3.2 Wastewater Feed Pump. The wastewater is pumped from the 
refrigerated container using a variable-speed peristaltic pump drive 
equipped with a peristaltic pump head. Add the feed solution to the 
benchtop bioreactor through a fitting on the top

[[Page 961]]

flange. Determine the rate of feed addition to provide a retention time 
in the benchtop bioreactor that is numerically equivalent to the 
retention time in the full-scale system. The wastewater shall be fed at 
a rate sufficient to achieve 90 to 100 percent of the full-scale system 
residence time.
    6.3.3 Treated wastewater feed. The benchtop bioreactor effluent 
exits at the bottom of the reactor through a tube and proceeds to the 
clarifier.
    6.4 Clarifier. The effluent flows to a separate closed clarifier 
that allows separation of biomass and effluent (e.g., 2-liter pear-
shaped glass separatory funnel, modified by removing the stopcock and 
adding a 25-mm OD glass tube at the bottom). Benchtop bioreactor 
effluent enters the clarifier through a tube inserted to a depth of 0.08 
m (3 in.) through a stopper at the top of the clarifier. System effluent 
flows from a tube inserted through the stopper at the top of the 
clarifier to a drain (or sample bottle when sampling). The underflow 
from the clarifier leaves from the glass tube at the bottom of the 
clarifier. Flexible tubing connects this fitting to the sludge recycle 
pump. This pump is coupled to a variable speed pump drive. The discharge 
from this pump is returned through a tube inserted in a port on the side 
of the benchtop bioreactor. An additional port is provided near the 
bottom of the benchtop bioreactor for sampling the reactor contents. The 
mixed liquor from the benchtop bioreactor flows into the center of the 
clarifier. The clarified system effluent separates from the biomass and 
flows through an exit near the top of the clarifier. There shall be no 
headspace in the clarifier.
    6.5 Temperature Control Apparatus. Capable of maintaining the system 
at a temperature equal to the temperature of the full-scale system. The 
average temperature should be maintained within [plusmn]2 [deg]C of the 
set point.
    6.5.1 Temperature Monitoring Device. A resistance type temperature 
probe or a thermocouple connected to a temperature readout with a 
resolution of 0.1 [deg]C or better.
    6.5.2 Benchtop Bioreactor Heater. The heater is connected to the 
temperature control device.
    6.6 Oxygen Control System. Maintain the dissolved oxygen 
concentration at the levels present in the full-scale system. Target 
full-scale activated sludge systems with dissolved oxygen concentration 
below 2 mg/L are required to maintain the dissolved oxygen concentration 
in the benchtop ioreactor within 0.5 mg/L of the target dissolved oxygen 
level. Target full-scale activated sludge systems with dissolved oxygen 
concentration above 2 mg/L are required to maintain the dissolved oxygen 
concentration in the benchtop bioreactor within 1.5 mg/L of the target 
dissolved oxygen concentration; however, for target full-scale activated 
sludge systems with dissolved oxygen concentrations above 2 mg/L, the 
dissolved oxygen concentration in the benchtop bioreactor may not drop 
below 1.5 mg/L. If the benchtop bioreactor is outside the control range, 
the dissolved oxygen is noted and the reactor operation is adjusted.
    6.6.1 Dissolved Oxygen Monitor. Dissolved oxygen is monitored with a 
polarographic probe (gas permeable membrane) connected to a dissolved 
oxygen meter (e.g., 0 to 15 mg/L, 0 to 50 [deg]C).
    6.6.2 Benchtop Bioreactor Pressure Monitor. The benchtop bioreactor 
pressure is monitored through a port in the top flange of the reactor. 
This is connected to a gauge control with a span of 13-cm water vacuum 
to 13-cm water pressure or better. A relay is activated when the vacuum 
exceeds an adjustable setpoint which opens a solenoid valve (normally 
closed), admitting oxygen to the system. The vacuum setpoint controlling 
oxygen addition to the system shall be set at approximately 2.5 [plusmn] 
0.5 cm water and maintained at this setting except during brief periods 
when the dissolved oxygen concentration is adjusted.
    6.7 Connecting Tubing. All connecting tubing shall be Teflon or 
equivalent in impermeability. The only exception to this specification 
is the tubing directly inside the pump head of the wastewater feed pump, 
which may be Viton, Silicone or another type of flexible tubing.
    Note: Mention of trade names or products does not constitute 
endorsement by the U.S. Environmental Protection Agency.

                       7.0 Reagents and Standards

    7.1 Wastewater. Obtain a representative sample of wastewater at the 
inlet to the full-scale treatment plant if there is an existing full-
scale treatment plant (see section 6.3). If there is no existing full-
scale treatment plant, obtain the wastewater sample as close to the 
point of determination as possible. Collect the sample by pumping the 
wastewater into the 20-L collapsible container. The loss of volatiles 
shall be minimized from the wastewater by collapsing the container 
before filling, by minimizing the time of filling, and by avoiding a 
headspace in the container after filling. If the wastewater requires the 
addition of nutrients to support the biomass growth and maintain biomass 
characteristics, those nutrients are added and mixed with the container 
contents after the container is filled.
    7.2 Biomass. Obtain the biomass or activated sludge used for rate 
constant determination in the bench-scale process from the existing 
full-scale process or from a representative biomass culture (e.g., 
biomass that has been developed for a future full-scale process). This 
biomass is preferentially obtained from a thickened acclimated mixed 
liquor sample. Collect the sample either by

[[Page 962]]

bailing from the mixed liquor in the aeration tank with a weighted 
container, or by collecting aeration tank effluent at the effluent 
overflow weir. Transport the sample to the laboratory within no more 
than 4 hours of collection. Maintain the biomass concentration in the 
benchtop bioreactor at the level of the full-scale system +10 percent 
throughout the sampling period of the test method.

       8.0 Sample Collection, Preservation, Storage, and Transport

    8.1 Benchtop Bioreactor Operation. Charge the mixed liquor to the 
benchtop bioreactor, minimizing headspace over the liquid surface to 
minimize entrainment of mixed liquor in the circulating gas. Fasten the 
benchtop bioreactor headplate to the reactor over the liquid surface. 
Maintain the temperature of the contents of the benchtop bioreactor 
system at the temperature of the target full-scale system, [plusmn]2 
[deg]C, throughout the testing period. Monitor and record the 
temperature of the benchtop bioreactor contents at least to the nearest 
0.1 [deg]C.
    8.1.1 Wastewater Storage. Collect the wastewater sample in the 20-L 
collapsible container. Store the container at 4 [deg]C throughout the 
testing period. Connect the container to the benchtop bioreactor feed 
pump.
    8.1.2 Wastewater Flow Rate.
    8.1.2.1 The hydraulic residence time of the aeration tank is 
calculated as the ratio of the volume of the tank (L) to the flow rate 
(L/min). At the beginning of a test, the container shall be connected to 
the feed pump and solution shall be pumped to the benchtop bioreactor at 
the required flow rate to achieve the calculated hydraulic residence 
time of wastewater in the aeration tank.
[GRAPHIC] [TIFF OMITTED] TR17OC00.547

Where:

Qtest = wastewater flow rate (L/min)
Qfs = average flow rate of full-scale process (L/min)
Vfs = volume of full-scale aeration tank (L)

    8.1.2.2 The target flow rate in the test apparatus is the same as 
the flow rate in the target full-scale process multiplied by the ratio 
of benchtop bioreactor volume (e.g., 6 L) to the volume of the full-
scale aeration tank. The hydraulic residence time shall be maintained at 
90 to 100 percent of the residence time maintained in the full-scale 
unit. A nominal flow rate is set on the pump based on a pump 
calibration. Changes in the elasticity of the tubing in the pump head 
and the accumulation of material in the tubing affect this calibration. 
The nominal pumping rate shall be changed as necessary based on 
volumetric flow measurements. Discharge the benchtop bioreactor effluent 
to a wastewater storage, treatment, or disposal facility, except during 
sampling or flow measurement periods.
    8.1.3 Sludge Recycle Rate. Set the sludge recycle rate at a rate 
sufficient to prevent accumulation in the bottom of the clarifier. Set 
the air circulation rate sufficient to maintain the biomass in 
suspension.
    8.1.4 Benchtop Bioreactor Operation and Maintenance. Temperature, 
dissolved oxygen concentration, exit vent flow rate, benchtop bioreactor 
effluent flow rate, and air circulation rate shall be measured and 
recorded three times throughout each day of benchtop bioreactor 
operation. If other parameters (such as pH) are measured and maintained 
in the target full-scale unit, these parameters, where appropriate, 
shall be monitored and maintained to target full-scale specifications in 
the benchtop bioreactor. At the beginning of each sampling period 
(Section 8.2), sample the benchtop bioreactor contents for suspended 
solids analysis. Take this sample by loosening a clamp on a length of 
tubing attached to the lower side port. Determine the suspended solids 
gravimetrically by the Gooch crucible/glass fiber filter method for 
total suspended solids, in accordance with Standard Methods\3\ or 
equivalent. When necessary, sludge shall be wasted from the lower side 
port of the benchtop bioreactor, and the volume that is wasted shall be 
replaced with an equal volume of the reactor effluent. Add thickened 
activated sludge mixed liquor as necessary to the benchtop bioreactor to 
increase the suspended solids concentration to the desired level. Pump 
this mixed liquor to the benchtop bioreactor through the upper side port 
(Item 24 in Figure 304A-1). Change the membrane on the dissolved oxygen 
probe before starting the test. Calibrate the oxygen probe immediately 
before the start of the test and each time the membrane is changed.
    8.1.5 Inspection and Correction Procedures. If the feed line tubing 
becomes clogged, replace with new tubing. If the feed flow rate is not 
within 5 percent of target flow any time the flow rate is measured, 
reset pump or check the flow measuring device and measure flow rate 
again until target flow rate is achieved.

[[Page 963]]

    8.2 Test Sampling. At least two and one half hydraulic residence 
times after the system has reached the targeted specifications shall be 
permitted to elapse before the first sample is taken. Effluent samples 
of the clarifier discharge (Item 20 in Figure 304A-1) and the influent 
wastewater feed are collected in 40-mL septum vials to which two drops 
of 1:10 hydrochloric acid (HCl) in water have been added. Sample the 
clarifier discharge directly from the drain line. These samples will be 
composed of the entire flow from the system for a period of several 
minutes. Feed samples shall be taken from the feed pump suction line 
after temporarily stopping the benchtop bioreactor feed, removing a 
connector, and squeezing the collapsible feed container. Store both 
influent and effluent samples at 4 [deg]C immediately after collection 
and analyze within 8 hours of collection.
    8.2.1 Frequency of Sampling. During the test, sample and analyze the 
wastewater feed and the clarifier effluent at least six times. The 
sampling intervals shall be separated by at least 8 hours. During any 
individual sampling interval, sample the wastewater feed simultaneously 
with or immediately after the effluent sample. Calculate the relative 
standard deviation (RSD) of the amount removed (i.e., effluent 
concentration--wastewater feed concentration). The RSD values shall be < 
15 percent. If an RSD value is  15 percent, continue sampling 
and analyzing influent and effluent sets of samples until the RSD values 
are within specifications.
    8.2.2 Sampling After Exposure of System to Atmosphere. If, after 
starting sampling procedures, the benchtop bioreactor system is exposed 
to the atmosphere (due to leaks, maintenance, etc.), allow at least one 
hydraulic residence time to elapse before resuming sampling.

                           9.0 Quality Control

    9.1 Dissolved Oxygen. Fluctuation in dissolved oxygen concentration 
may occur for numerous reasons, including undetected gas leaks, 
increases and decreases in mixed liquor suspended solids resulting from 
cell growth and solids loss in the effluent stream, changes in diffuser 
performance, cycling of effluent flow rate, and overcorrection due to 
faulty or sluggish dissolved oxygen probe response. Control the 
dissolved oxygen concentration in the benchtop bioreactor by changing 
the proportion of oxygen in the circulating aeration gas. Should the 
dissolved oxygen concentration drift below the designated experimental 
condition, bleed a small amount of aeration gas from the system on the 
pressure side (i.e., immediately upstream of one of the diffusers). This 
will create a vacuum in the system, triggering the pressure sensitive 
relay to open the solenoid valve and admit oxygen to the system. Should 
the dissolved oxygen concentration drift above the designated 
experimental condition, slow or stop the oxygen input to the system 
until the dissolved oxygen concentration approaches the correct level.
    9.2 Sludge Wasting.
    9.2.1 Determine the suspended solids concentration (section 8.1.4) 
at the beginning of a test, and once per day thereafter during the test. 
If the test is completed within a two day period, determine the 
suspended solids concentration after the final sample set is taken. If 
the suspended solids concentration exceeds the specified concentration, 
remove a fraction of the sludge from the benchtop bioreactor. The 
required volume of mixed liquor to remove is determined as follows:
[GRAPHIC] [TIFF OMITTED] TR17OC00.548

Where:

Vw is the wasted volume (Liters),
Vr is the volume of the benchtop bioreactor (Liters),
Sm is the measured solids (g/L), and
Ss is the specified solids (g/L).

    9.2.2 Remove the mixed liquor from the benchtop bioreactor by 
loosening a clamp on the mixed liquor sampling tube and allowing the 
required volume to drain to a graduated flask. Clamp the tube when the 
correct volume has been wasted. Replace the volume of the liquid wasted 
by pouring the same volume of effluent back into the benchtop 
bioreactor. Dispose of the waste sludge properly.
    9.3 Sludge Makeup. In the event that the suspended solids 
concentration is lower than the specifications, add makeup sludge back 
into the benchtop bioreactor. Determine the amount of sludge added by 
the following equation:

[[Page 964]]

[GRAPHIC] [TIFF OMITTED] TR17OC00.549

Where:

Vw is the volume of sludge to add (Liters),
Vr is the volume of the benchtop bioreactor (Liters),
Sw is the solids in the makeup sludge (g/L),
Sm is the measured solids (g/L), and Ss is the 
          specified solids (g/L).

                  10.0 Calibration and Standardization

    10.1 Wastewater Pump Calibration. Determine the wastewater flow rate 
by collecting the system effluent for a time period of at least one 
hour, and measuring the volume with a graduated cylinder. Record the 
collection time period and volume collected. Determine flow rate. Adjust 
the pump speed to deliver the specified flow rate.
    10.2 Calibration Standards. Prepare calibration standards from pure 
certified standards in an aqueous medium. Prepare and analyze three 
concentrations of calibration standards for each target component (or 
for a mixture of components) in triplicate daily throughout the analyses 
of the test samples. At each concentration level, a single calibration 
shall be within 5 percent of the average of the three calibration 
results. The low and medium calibration standards shall bracket the 
expected concentration of the effluent (treated) wastewater. The medium 
and high standards shall bracket the expected influent concentration.

                       11.0 Analytical Procedures

    11.1 Analysis. If the identity of the compounds of interest in the 
wastewater is not known, a representative sample of the wastewater shall 
be analyzed in order to identify all of the compounds of interest 
present. A gas chromatography/mass spectrometry screening method is 
recommended.
    11.1.1 After identifying the compounds of interest in the 
wastewater, develop and/or use one or more analytical techniques capable 
of measuring each of those compounds (more than one analytical technique 
may be required, depending on the characteristics of the wastewater). 
Test Method 18, found in appendix A of 40 CFR 60, may be used as a 
guideline in developing the analytical technique. Purge and trap 
techniques may be used for analysis providing the target components are 
sufficiently volatile to make this technique appropriate. The limit of 
quantitation for each compound shall be determined (see reference 1). If 
the effluent concentration of any target compound is below the limit of 
quantitation determined for that compound, the operation of the Method 
304 unit may be altered to attempt to increase the effluent 
concentration above the limit of quantitation. Modifications to the 
method shall be approved prior to the test. The request should be 
addressed to Method 304 contact, Emissions Measurement Center, Mail Drop 
19, U.S. Environmental Protection Agency, Research Triangle Park, NC 
27711.

Method 304B: Determination of Biodegradation Rates of Organic Compounds 
                            (Scrubber Option)

                        1.0 Scope and Application

    1.1 Applicability. This method is applicable for the determination 
of biodegradation rates of organic compounds in an activated sludge 
process. The test method is designed to evaluate the ability of an 
aerobic biological reaction system to degrade or destroy specific 
components in waste streams. The method may also be used to determine 
the effects of changes in wastewater composition on operation. The 
biodegradation rates determined by utilizing this method are not 
representative of a full-scale system. Full-scale systems embody 
biodegradation and air emissions in competing reactions. This method 
measures biodegradation in absence

[[Page 967]]

of air emissions. The rates measured by this method shall be used in 
conjunction with the procedures listed in appendix C of this part to 
calculate the fraction emitted to the air versus the fraction 
biodegraded.

                          2.0 Summary of Method

    2.1 A self-contained benchtop bioreactor system is assembled in the 
laboratory. A sample of mixed liquor is added and the waste stream is 
then fed continuously. The benchtop bioreactor is operated under 
conditions nearly identical to the target full-scale activated sludge 
process, except that air emissions are not a factor. The benchtop 
bioreactor temperature, dissolved oxygen concentration, average 
residence time in the reactor, waste composition, biomass concentration, 
and biomass composition of the target full-scale process are the 
parameters which are duplicated in the laboratory system. Biomass shall 
be removed from the target full-scale activated sludge unit and held for 
no more than 4 hours prior to use in the benchtop bioreactor. If 
antifoaming agents are used in the full-scale system, they shall also be 
used in the benchtop bioreactor. The feed flowing into and the effluent 
exiting the benchtop bioreactor are analyzed to determine the 
biodegradation rates of the target compounds. The choice of analytical 
methodology for measuring the compounds of interest at the inlet and 
outlet to the benchtop bioreactor are left to the discretion of the 
source, except where validated methods are available.

                               5.0 Safety

    5.1 If explosive gases are produced as a byproduct of biodegradation 
and could realistically pose a hazard, closely monitor headspace 
concentration of these gases to ensure laboratory safety. Placement of 
the benchtop bioreactor system inside a laboratory hood is recommended 
regardless of byproducts produced.

                       6.0 Equipment and Supplies

    Note: Figure 304B-1 illustrates a typical laboratory apparatus used 
to measure biodegradation rates. While the following description refers 
to Figure 304B-1, the EPA recognizes that alternative reactor 
configurations, such as alternative reactor shapes and locations of 
probes and the feed inlet, will also meet the intent of this method. 
Ensure that the benchtop bioreactor system is self-contained and 
isolated from the atmosphere by leak-checking fittings, tubing, etc.
    6.1 Benchtop Bioreactor. The biological reaction is conducted in a 
biological oxidation reactor of at least 6-liters capacity. The benchtop 
bioreactor is sealed and equipped with internal probes for controlling 
and monitoring dissolved oxygen and internal temperature. The top of the 
benchtop bioreactor is equipped for aerators, gas flow ports, and 
instrumentation (while ensuring that no leaks to the atmosphere exist 
around the fittings).
    6.2 Aeration gas. Aeration gas is added to the benchtop bioreactor 
through three diffusers, which are glass tubes that extend to the bottom 
fifth of the reactor depth. A pure oxygen pressurized cylinder is 
recommended in order to maintain the specified oxygen concentration. 
Install a blower (e.g., Diaphragm Type, 15 SCFH capacity) to blow the 
aeration gas into the benchtop bioreactor diffusers. Measure the 
aeration gas flow rate with a rotameter (e.g., 0-15 SCFH recommended). 
The aeration gas will rise through the benchtop bioreactor, dissolving 
oxygen into the mixture in the process. The aeration gas must provide 
sufficient agitation to keep the solids in suspension. Provide an exit 
for the aeration gas from the top flange of the benchtop bioreactor 
through a water-cooled (e.g., Allihn-type) vertical condenser. Install 
the condenser through a gas-tight fitting in the benchtop bioreactor 
closure. Design the system so that at least 10 percent of the gas flows 
through an alkaline scrubber containing 175 mL of 45 percent by weight 
solution of potassium hydroxide (KOH) and 5 drops of 0.2 percent 
alizarin yellow dye. Route the balance of the gas through an adjustable 
scrubber bypass. Route all of the gas through a 1-L knock-out flask to 
remove entrained moisture and then to the intake of the blower. The 
blower recirculates the gas to the benchtop bioreactor.
    6.3 Wastewater Feed. Supply the wastewater feed to the benchtop 
bioreactor in a collapsible low-density polyethylene container or 
collapsible liner in a container (e.g., 20 L) equipped with a spigot cap 
(collapsible containers or liners of other material may be required due 
to the permeability of some volatile compounds through polyethylene). 
Obtain the wastewater feed by sampling the wastewater feed in the target 
process. A representative sample of wastewater shall be obtained from 
the piping leading to the aeration tank. This sample may be obtained 
from existing sampling valves at the discharge of the wastewater feed 
pump, or collected from a pipe discharging to the aeration tank, or by 
pumping from a well-mixed equalization tank upstream from the aeration 
tank. Alternatively, wastewater can be pumped continuously to the 
laboratory apparatus from a bleed stream taken from the equalization 
tank of the full-scale treatment system.
    6.3.1 Refrigeration System. Keep the wastewater feed cool by ice or 
by refrigeration to 4 [deg]C. If using a bleed stream from the

[[Page 968]]

equalization tank, refrigeration is not required if the residence time 
in the bleed stream is less than five minutes.
    6.3.2 Wastewater Feed Pump. The wastewater is pumped from the 
refrigerated container using a variable-speed peristaltic pump drive 
equipped with a peristaltic pump head. Add the feed solution to the 
benchtop bioreactor through a fitting on the top flange. Determine the 
rate of feed addition to provide a retention time in the benchtop 
bioreactor that is numerically equivalent to the retention time in the 
target full-scale system. The wastewater shall be fed at a rate 
sufficient to achieve 90 to 100 percent of the target full-scale system 
residence time.
    6.3.3 Treated wastewater feed. The benchtop bioreactor effluent 
exits at the bottom of the reactor through a tube and proceeds to the 
clarifier.
    6.4 Clarifier. The effluent flows to a separate closed clarifier 
that allows separation of biomass and effluent (e.g., 2-liter pear-
shaped glass separatory funnel, modified by removing the stopcock and 
adding a 25-mm OD glass tube at the bottom). Benchtop bioreactor 
effluent enters the clarifier through a tube inserted to a depth of 0.08 
m (3 in.) through a stopper at the top of the clarifier. System effluent 
flows from a tube inserted through the stopper at the top of the 
clarifier to a drain (or sample bottle when sampling). The underflow 
from the clarifier leaves from the glass tube at the bottom of the 
clarifier. Flexible tubing connects this fitting to the sludge recycle 
pump. This pump is coupled to a variable speed pump drive. The discharge 
from this pump is returned through a tube inserted in a port on the side 
of the benchtop bioreactor. An additional port is provided near the 
bottom of the benchtop bioreactor for sampling the reactor contents. The 
mixed liquor from the benchtop bioreactor flows into the center of the 
clarifier. The clarified system effluent separates from the biomass and 
flows through an exit near the top of the clarifier. There shall be no 
headspace in the clarifier.
    6.5 Temperature Control Apparatus. Capable of maintaining the system 
at a temperature equal to the temperature of the full-scale system. The 
average temperature should be maintained within [plusmn]2 [deg]C of the 
set point.
    6.5.1 Temperature Monitoring Device. A resistance type temperature 
probe or a thermocouple connected to a temperature readout with a 
resolution of 0.1 [deg]C or better.
    6.5.2 Benchtop Bioreactor Heater. The heater is connected to the 
temperature control device.
    6.6 Oxygen Control System. Maintain the dissolved oxygen 
concentration at the levels present in the full-scale system. Target 
full-scale activated sludge systems with dissolved oxygen concentration 
below 2 mg/L are required to maintain the dissolved oxygen concentration 
in the benchtop bioreactor within 0.5 mg/L of the target dissolved 
oxygen level. Target full-scale activated sludge systems with dissolved 
oxygen concentration above 2 mg/L are required to maintain the dissolved 
oxygen concentration in the benchtop bioreactor within 1.5 mg/L of the 
target dissolved oxygen concentration; however, for target full-scale 
activated sludge systems with dissolved oxygen concentrations above 2 
mg/L, the dissolved oxygen concentration in the benchtop bioreactor may 
not drop below 1.5 mg/L. If the benchtop bioreactor is outside the 
control range, the dissolved oxygen is noted and the reactor operation 
is adjusted.
    6.6.1 Dissolved Oxygen Monitor. Dissolved oxygen is monitored with a 
polarographic probe (gas permeable membrane) connected to a dissolved 
oxygen meter (e.g., 0 to 15 mg/L, 0 to 50 [deg]C).
    6.6.2 Benchtop Bioreactor Pressure Monitor. The benchtop bioreactor 
pressure is monitored through a port in the top flange of the reactor. 
This is connected to a gauge control with a span of 13-cm water vacuum 
to 13-cm water pressure or better. A relay is activated when the vacuum 
exceeds an adjustable setpoint which opens a solenoid valve (normally 
closed), admitting oxygen to the system. The vacuum setpoint controlling 
oxygen addition to the system shall be set at approximately 2.5 [plusmn] 
0.5 cm water and maintained at this setting except during brief periods 
when the dissolved oxygen concentration is adjusted.
    6.7 Connecting Tubing. All connecting tubing shall be Teflon or 
equivalent in impermeability. The only exception to this specification 
is the tubing directly inside the pump head of the wastewater feed pump, 
which may be Viton, Silicone or another type of flexible tubing.
    Note: Mention of trade names or products does not constitute 
endorsement by the U.S. Environmental Protection Agency.

                       7.0. Reagents and Standards

    7.1 Wastewater. Obtain a representative sample of wastewater at the 
inlet to the full-scale treatment plant if there is an existing full-
scale treatment plant (See Section 6.3). If there is no existing full-
scale treatment plant, obtain the wastewater sample as close to the 
point of determination as possible. Collect the sample by pumping the 
wastewater into the 20-L collapsible container. The loss of volatiles 
shall be minimized from the wastewater by collapsing the container 
before filling, by minimizing the time of filling, and by avoiding a 
headspace in the container after filling. If the wastewater requires the 
addition of nutrients to support the biomass growth and maintain biomass 
characteristics, those nutrients are added and mixed with the container 
contents after the container is filled.

[[Page 969]]

    7.2 Biomass. Obtain the biomass or activated sludge used for rate 
constant determination in the bench-scale process from the existing 
full-scale process or from a representative biomass culture (e.g., 
biomass that has been developed for a future full-scale process). This 
biomass is preferentially obtained from a thickened acclimated mixed 
liquor sample. Collect the sample either by bailing from the mixed 
liquor in the aeration tank with a weighted container, or by collecting 
aeration tank effluent at the effluent overflow weir. Transport the 
sample to the laboratory within no more than 4 hours of collection. 
Maintain the biomass concentration in the benchtop bioreactor at the 
level of the target full-scale system +10 percent throughout the 
sampling period of the test method.

       8.0 Sample Collection, Preservation, Storage, and Transport

    8.1 Benchtop Bioreactor Operation. Charge the mixed liquor to the 
benchtop bioreactor, minimizing headspace over the liquid surface to 
minimize entrainment of mixed liquor in the circulating gas. Fasten the 
benchtop bioreactor headplate to the reactor over the liquid surface. 
Maintain the temperature of the contents of the benchtop bioreactor 
system at the temperature of the target full-scale system, [plusmn]2 
[deg]C, throughout the testing period. Monitor and record the 
temperature of the reactor contents at least to the nearest 0.1 [deg]C.
    8.1.1 Wastewater Storage. Collect the wastewater sample in the 20-L 
collapsible container. Store the container at 4 [deg]C throughout the 
testing period. Connect the container to the benchtop bioreactor feed 
pump.
    8.1.2 Wastewater Flow Rate.
    8.1.2.1 The hydraulic residence time of the aeration tank is 
calculated as the ratio of the volume of the tank (L) to the flow rate 
(L/min). At the beginning of a test, the container shall be connected to 
the feed pump and solution shall be pumped to the benchtop bioreactor at 
the required flow rate to achieve the calculated hydraulic residence 
time of wastewater in the aeration tank.
[GRAPHIC] [TIFF OMITTED] TR17OC00.555

Where:

Qtest = wastewater flow rate (L/min)
Qfs = average flow rate of full-scale process (L/min)
Vfs = volume of full-scale aeration tank (L)

    8.1.2.2 The target flow rate in the test apparatus is the same as 
the flow rate in the target full-scale process multiplied by the ratio 
of benchtop bioreactor volume (e.g., 6 L) to the volume of the full-
scale aeration tank. The hydraulic residence time shall be maintained at 
90 to 100 percent of the residence time maintained in the target full-
scale unit. A nominal flow rate is set on the pump based on a pump 
calibration. Changes in the elasticity of the tubing in the pump head 
and the accumulation of material in the tubing affect this calibration. 
The nominal pumping rate shall be changed as necessary based on 
volumetric flow measurements. Discharge the benchtop bioreactor effluent 
to a wastewater storage, treatment, or disposal facility, except during 
sampling or flow measurement periods.
    8.1.3 Sludge Recycle Rate. Set the sludge recycle rate at a rate 
sufficient to prevent accumulation in the bottom of the clarifier. Set 
the air circulation rate sufficient to maintain the biomass in 
suspension.
    8.1.4 Benchtop Bioreactor Operation and Maintenance. Temperature, 
dissolved oxygen concentration, flow rate, and air circulation rate 
shall be measured and recorded three times throughout each day of 
testing. If other parameters (such as pH) are measured and maintained in 
the target full-scale unit, these parameters shall, where appropriate, 
be monitored and maintained to full-scale specifications in the benchtop 
bioreactor. At the beginning of each sampling period (section 8.2), 
sample the benchtop bioreactor contents for suspended solids analysis. 
Take this sample by loosening a clamp on a length of tubing attached to 
the lower side port. Determine the suspended solids gravimetrically by 
the Gooch crucible/glass fiber filter method for total suspended solids, 
in accordance with Standard Methods3 or equivalent. When 
necessary, sludge shall be wasted from the lower side port of the 
benchtop bioreactor, and the volume that is wasted shall be replaced 
with an equal volume of the benchtop bioreactor effluent. Add thickened 
activated sludge mixed liquor as necessary to the benchtop bioreactor to 
increase the suspended solids concentration to the desired level. Pump 
this mixed liquor to the benchtop bioreactor through the upper side port 
(Item 24 in Figure 304B-1). Change the membrane on the dissolved oxygen 
probe before starting the test. Calibrate the oxygen probe immediately 
before the start of the test and each time the membrane is changed.

[[Page 970]]

The scrubber solution shall be replaced each weekday with 175 mL 45 
percent W/W KOH solution to which five drops of 0.2 percent alizarin 
yellow indicator in water have been added. The potassium hydroxide 
solution in the alkaline scrubber shall be changed if the alizarin 
yellow dye color changes.
    8.1.5 Inspection and Correction Procedures. If the feed line tubing 
becomes clogged, replace with new tubing. If the feed flow rate is not 
within 5 percent of target flow any time the flow rate is measured, 
reset pump or check the flow measuring device and measure flow rate 
again until target flow rate is achieved.
    8.2 Test Sampling. At least two and one half hydraulic residence 
times after the system has reached the targeted specifications shall be 
permitted to elapse before the first sample is taken. Effluent samples 
of the clarifier discharge (Item 20 in Figure 304B-1) and the influent 
wastewater feed are collected in 40-mL septum vials to which two drops 
of 1:10 hydrochloric acid (HCl) in water have been added. Sample the 
clarifier discharge directly from the drain line. These samples will be 
composed of the entire flow from the system for a period of several 
minutes. Feed samples shall be taken from the feed pump suction line 
after temporarily stopping the benchtop bioreactor feed, removing a 
connector, and squeezing the collapsible feed container. Store both 
influent and effluent samples at 4 [deg]C immediately after collection 
and analyze within 8 hours of collection.
    8.2.1 Frequency of Sampling. During the test, sample and analyze the 
wastewater feed and the clarifier effluent at least six times. The 
sampling intervals shall be separated by at least 8 hours. During any 
individual sampling interval, sample the wastewater feed simultaneously 
with or immediately after the effluent sample. Calculate the RSD of the 
amount removed (i.e., effluent concentration--wastewater feed 
concentration). The RSD values shall be <15 percent. If an RSD value is 
15 percent, continue sampling and analyzing influent and 
effluent sets of samples until the RSD values are within specifications.
    8.2.2 Sampling After Exposure of System to Atmosphere. If, after 
starting sampling procedures, the benchtop bioreactor system is exposed 
to the atmosphere (due to leaks, maintenance, etc.), allow at least one 
hydraulic residence time to elapse before resuming sampling.

                           9.0 Quality Control

    9.1 Dissolved Oxygen. Fluctuation in dissolved oxygen concentration 
may occur for numerous reasons, including undetected gas leaks, 
increases and decreases in mixed liquor suspended solids resulting from 
cell growth and solids loss in the effluent stream, changes in diffuser 
performance, cycling of effluent flow rate, and overcorrection due to 
faulty or sluggish dissolved oxygen probe response. Control the 
dissolved oxygen concentration in the benchtop bioreactor by changing 
the proportion of oxygen in the circulating aeration gas. Should the 
dissolved oxygen concentration drift below the designated experimental 
condition, bleed a small amount of aeration gas from the system on the 
pressure side (i.e., immediately upstream of one of the diffusers). This 
will create a vacuum in the system, triggering the pressure sensitive 
relay to open the solenoid valve and admit oxygen to the system. Should 
the dissolved oxygen concentration drift above the designated 
experimental condition, slow or stop the oxygen input to the system 
until the dissolved oxygen concentration approaches the correct level.
    9.2 Sludge Wasting.
    9.2.1 Determine the suspended solids concentration (section 8.1.4) 
at the beginning of a test, and once per day thereafter during the test. 
If the test is completed within a two day period, determine the 
suspended solids concentration after the final sample set is taken. If 
the suspended solids concentration exceeds the specified concentration, 
remove a fraction of the sludge from the benchtop bioreactor. The 
required volume of mixed liquor to remove is determined as follows:
[GRAPHIC] [TIFF OMITTED] TR17OC00.556

Where:

Vw is the wasted volume (Liters),
Vr is the volume of the benchtop bioreactor (Liters),
Sm is the measured solids (g/L), and
Ss is the specified solids (g/L).

    9.2.2 Remove the mixed liquor from the benchtop bioreactor by 
loosening a clamp on the mixed liquor sampling tube and allowing the 
required volume to drain to a graduated flask. Clamp the tube when the 
correct volume has been wasted. Replace the volume of

[[Page 971]]

the liquid wasted by pouring the same volume of effluent back into the 
benchtop bioreactor. Dispose of the waste sludge properly.
    9.3 Sludge Makeup. In the event that the suspended solids 
concentration is lower than the specifications, add makeup sludge back 
into the benchtop bioreactor. Determine the amount of sludge added by 
the following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.557

Where:

Vw is the volume of sludge to add (Liters),
Vr is the volume of the benchtop bioreactor (Liters),
Sw is the solids in the makeup sludge (g/L),
Sm is the measured solids (g/L), and
Ss is the specified solids (g/L).

                  10.0 Calibration and Standardizations

    10.1 Wastewater Pump Calibration. Determine the wastewater flow rate 
by collecting the system effluent for a time period of at least one 
hour, and measuring the volume with a graduated cylinder. Record the 
collection time period and volume collected. Determine flow rate. Adjust 
the pump speed to deliver the specified flow rate.
    10.2 Calibration Standards. Prepare calibration standards from pure 
certified standards in an aqueous medium. Prepare and analyze three 
concentrations of calibration standards for each target component (or 
for a mixture of components) in triplicate daily throughout the analyses 
of the test samples. At each concentration level, a single calibration 
shall be within 5 percent of the average of the three calibration 
results. The low and medium calibration standards shall bracket the 
expected concentration of the effluent (treated) wastewater. The medium 
and high standards shall bracket the expected influent concentration.

                     11.0 Analytical Test Procedures

    11.1 Analysis. If the identity of the compounds of interest in the 
wastewater is not known, a representative sample of the wastewater shall 
be analyzed in order to identify all of the compounds of interest 
present. A gas chromatography/mass spectrometry screening method is 
recommended.
    11.1.1 After identifying the compounds of interest in the 
wastewater, develop and/or use one or more analytical technique capable 
of measuring each of those compounds (more than one analytical technique 
may be required, depending on the characteristics of the wastewater). 
Method 18, found in appendix A of 40 CFR 60, may be used as a guideline 
in developing the analytical technique. Purge and trap techniques may be 
used for analysis providing the target components are sufficiently 
volatile to make this technique appropriate. The limit of quantitation 
for each compound shall be determined.\1\ If the effluent concentration 
of any target compound is below the limit of quantitation determined for 
that compound, the operation of the Method 304 unit may be altered to 
attempt to increase the effluent concentration above the limit of 
quantitation. Modifications to the method shall be approved prior to the 
test. The request should be addressed to Method 304 contact, Emissions 
Measurement Center, Mail Drop 19, U.S. Environmental Protection Agency, 
Research Triangle Park, NC 27711.

                          2.0 Summary of Method

    2.1 The heated purge conditions established by Method 25D (40 CFR 
Part 60, Appendix A) are used to remove VOs from a 10 gram sample of 
waste suspended in a 50/50 solution of polyethylene glycol (PEG) and 
water. The purged VOs are quantified by using the sample collection and 
analytical techniques (e.g. gas chromatography) appropriate for the VOs 
present in the waste. The recovery efficiency of the sample collection 
and analytical technique is determined for each waste matrix. A 
correction factor is determined for each compound (if acceptable 
recovery criteria requirements are met of 70 to 130 percent recovery for 
every target compound), and the measured waste concentration is 
corrected with the correction factor for each compound. A minimum of 
three replicate waste samples shall be analyzed.

                               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 to determine the applicability of regulatory limitations 
prior to performing this test method.

                       6.0 Equipment and Supplies

    6.1 Method 25D Purge Apparatus.
    6.1.1 Purge Chamber. The purge chamber shall accommodate the 10 gram 
sample of waste suspended in a matrix of 50 mL of PEG and 50 mL of 
deionized, hydrocarbon-free water. Three fittings are used on the glass 
chamber top. Two 7 Ace-threads are used for the purge gas inlet 
and outlet connections. A 50 Ace-thread is used to connect the 
top of the chamber to the base (see Figure 305-1). The base of the 
chamber has a side-arm equipped with a 22 Sovirel fitting to 
allow for easy sample introductions into the chamber. The dimensions of 
the chamber are shown in Figure 305-1.
    6.1.2 Flow Distribution Device (FDD). The FDD enhances the gas-to-
liquid contact for improved purging efficiency. The FDD is a 6 mm OD 
(0.2 in) by 30 cm (12 in) long glass tube equipped with four arm 
bubblers as shown in Figure 305-1. Each arm shall have an opening of 1 
mm (0.04 in) in diameter.
    6.1.3 Coalescing Filter. The coalescing filter serves to discourage 
aerosol formation of sample gas once it leaves the purge chamber. The 
glass filter has a fritted disc mounted 10 cm (3.9 in) from the bottom. 
Two 7 Ace-threads are used for the inlet and outlet 
connections. The dimensions of the chamber are shown in Figure 305-2.
    6.1.4 Oven. A forced convection airflow oven capable of maintaining 
the purge chamber and coalescing filter at 75 [plusmn] 2 [deg]C (167 
[plusmn] 3.6 [deg]F).
    6.1.5 Toggle Valve. An on/off valve constructed from brass or 
stainless steel rated to 100 psig. This valve is placed in line between 
the purge nitrogen source and the flow controller.
    6.1.6 Flow Controller. High-quality stainless steel flow controller 
capable of restricting a flow of nitrogen to 6 [plusmn] 0.06 L/min (0.2 
[plusmn] 0.002 ft3/min) at 40 psig.
    6.1.7 Polyethylene Glycol Cleaning System.
    6.1.7.1 Round-Bottom Flask. One liter, three-neck glass round-bottom 
flask for cleaning PEG. Standard taper 24/40 joints are mounted on each 
neck.
    6.1.7.2 Heating Mantle. Capable of heating contents of the 1-L flask 
to 120 [deg]C (248 [deg]F).
    6.1.7.3 Nitrogen Bubbler. Teflon[reg] or glass tube, 0.25 in OD 
(6.35 mm).
    6.1.7.4 Temperature Sensor. Partial immersion glass thermometer.
    6.1.7.5 Hose Adapter. Glass with 24/40 standard tapered joint.
    6.2 Volatile Organic Recovery System.
    6.2.1 Splitter Valve (Optional). Stainless steel cross-pattern valve 
capable of splitting nominal flow rates from the purge flow of 6 L/min 
(0.2 ft3/min). The valve shall be maintained at 75 + 2 [deg]C 
(167 [plusmn] 3.6 [deg]F) in the heated zone and shall be placed 
downstream of the coalescing filter. It is recommended that 0.125 in OD 
(3.175 mm) tubing be used to direct the split vent flow from the heated 
zone. The back pressure caused by the 0.125 in OD (3.175 mm) tubing is 
critical for maintaining proper split valve operation.
    Note: The splitter valve design is optional; it may be used in cases 
where the concentration of a pollutant would saturate the adsorbents.
    6.2.2 Injection Port. Stainless steel 1/4 in OD (6.35 mm) 
compression fitting tee with a 6 mm (0.2 in) septum fixed on the top 
port. The injection port is the point of entry for the recovery study 
solution. If using a gaseous standard to determine recovery efficiency, 
connect the gaseous standard to the injection port of the tee.
    6.2.3 Knockout Trap (Optional but Recommended). A 25 mL capacity 
glass reservoir body with a full-stem impinger (to avoid leaks, a 
modified midget glass impinger with a screw cap and ball/socket clamps 
on the inlet and outlet is recommended). The empty impinger is placed in 
an ice water bath between the injection port and the sorbent cartridge. 
Its purpose is to reduce the water content of the purge gas (saturated 
at 75 [deg]C (167 [deg]F)) before the sorbent cartridge.
    6.2.4 Insulated Ice Bath. A 350 mL dewar or other type of insulated 
bath is used to

[[Page 975]]

maintain ice water around the knockout trap.
    6.2.5 Sorbent Cartridges. Commercially available glass or stainless 
steel cartridge packed with one or more appropriate sorbents. The amount 
of adsorbent packed in the cartridge depends on the breakthrough volume 
of the test compounds but is limited by back pressure caused by the 
packing (not to exceed 7 psig). More than one sorbent cartridge placed 
in series may be necessary depending upon the mixture of the measured 
components.
    6.2.6 Volumetric Glassware. Type A glass 10 mL volumetric flasks for 
measuring a final volume from the water catch in the knockout trap.
    6.2.7 Thermal Desorption Unit. A clam-shell type oven, used for the 
desorption of direct thermal desorption sorbent tubes. The oven shall be 
capable of increasing the temperature of the desorption tubes rapidly to 
recommended desorption temperature.
    6.2.8 Ultrasonic Bath. Small bath used to agitate sorbent material 
and desorption solvent. Ice water shall be used in the bath because of 
heat transfer caused by operation of the bath.
    6.2.9 Desorption Vials. Four-dram (15 mL) capacity borosilicate 
glass vials with Teflon-lined caps.
    6.3 Analytical System. A gas chromatograph (GC) is commonly used to 
separate and quantify compounds from the sample collection and recovery 
procedure. Method 18 (40 CFR Part 60, Appendix A) may be used as a 
guideline for determining the appropriate GC column and GC detector 
based on the test compounds to be determined. Other types of analytical 
instrumentation may be used (HPLC) in lieu of GC systems as long as the 
recovery efficiency criteria of this method are met.
    6.3.1 Gas Chromatograph (GC). The GC shall be equipped with a 
constant-temperature liquid injection port or a heated sampling loop/
valve system, as appropriate. The GC oven shall be temperature-
programmable over the useful range of the GC column. The choice of 
detectors is based on the test compounds to be determined.
    6.3.2 GC Column. Select the appropriate GC column based on (1) 
literature review or previous experience, (2) polarity of the analytes, 
(3) capacity of the column, or (4) resolving power (e.g., length, 
diameter, film thickness) required.
    6.3.3 Data System. A programmable electronic integrator for 
recording, analyzing, and storing the signal generated by the detector.

                       7.0 Reagents and Standards

    7.1 Method 25D Purge Apparatus.
    7.1.1 Polyethylene Glycol (PEG). Ninety-eight percent pure organic 
polymer with an average molecular weight of 400 g/mol. Volatile organics 
are removed from the PEG prior to use by heating to 120 [plusmn] 5 
[deg]C (248 [plusmn] 9 [deg]F) and purging with pure nitrogen at 1 L/min 
(0.04 ft3/min) for 2 hours. After purging and heating, the 
PEG is maintained at room temperature under a nitrogen purge maintained 
at 1 L/min (0.04 ft3/min) until used. A typical apparatus 
used to clean the PEG is shown in Figure 305-3.
    7.1.2 Water. Organic-free deionized water is required.
    7.1.3 Nitrogen. High-purity nitrogen (less than 0.5 ppm total 
hydrocarbons) is used to remove test compounds from the purge matrix. 
The source of nitrogen shall be regulated continuously to 40 psig before 
the on/off toggle valve.
    7.2 Volatile Organic Recovery System.
    7.2.1 Water. Organic-free deionized water is required.
    7.2.2 Desorption Solvent (when used). Appropriate high-purity (99.99 
percent) solvent for desorption shall be used. Analysis shall be 
performed (utilizing the same analytical technique as that used in the 
analysis of the waste samples) on each lot to determine purity.
    7.3 Analytical System. The gases required for GC operation shall be 
of the highest obtainable purity (hydrocarbon free). Consult the 
operating manual for recommended settings.

       8.0 Sample Collection, Preservation, Storage, and Transport

    8.1 Assemble the glassware and associated fittings (see Figures 305-
3 and 305-4, as appropriate) and leak-check the system (approximately 7 
psig is the target pressure). After an initial leak check, mark the 
pressure gauge and use the initial checkpoint to monitor for leaks 
throughout subsequent analyses. If the pressure in the system drops 
below the target pressure at any time during analysis, that analysis 
shall be considered invalid.
    8.2 Recovery Efficiency Determination. Determine the individual 
recovery efficiency (RE) for each of the target compounds in duplicate 
before the waste samples are analyzed. To determine the RE, generate a 
water blank (Section 11.1) and use the injection port to introduce a 
known volume of spike solution (or certified gaseous standard) 
containing all of the target compounds at the levels expected in the 
waste sample. Introduce the spike solution immediately after the 
nitrogen purge has been started (Section 8.3.2). Follow the procedures 
outlined in Section 8.3.3. Analyze the recovery efficiency samples using 
the techniques described in Section 11.2. Determine the recovery 
efficiency (Equation 305-1, Section 12.2) by comparing the amount of 
compound recovered to the theoretical amount spiked. Determine the RE 
twice for each compound; the relative

[[Page 976]]

standard deviation, (RSD) shall be [le] 10 percent for each compound. If 
the RSD for any compound is not [le] 10 percent, modify the sampling/
analytical procedure and complete an RE study in duplicate, or continue 
determining RE until the RSD meets the acceptable criteria. The average 
RE shall be 0.70 [le] RE [le] 1.30 for each compound. If the average RE 
does not meet these criteria, an alternative sample collection and/or 
analysis technique shall be developed and the recovery efficiency 
determination shall be repeated for that compound until the criteria are 
met for every target compound. Example modifications of the sampling/
analytical system include changing the adsorbent material, changing the 
desorption solvent, utilizing direct thermal desorption of test 
compounds from the sorbent tubes, utilizing another analytical 
technique.
    8.3 Sample Collection and Recovery.
    8.3.1 The sample collection procedure in Method 25D shall be used to 
collect (into a preweighed vial) 10 g of waste into PEG, cool, and ship 
to the laboratory. Remove the sample container from the cooler and wipe 
the exterior to remove any ice or water. Weigh the container and sample 
to the nearest 0.01 g and record the weight. Pour the sample from the 
container into the purge flask. Rinse the sample container three times 
with approximately 6 mL of PEG (or the volume needed to total 50 mL of 
PEG in the purge flask), transferring the rinses to the purge flask. Add 
50 mL of organic-free deionized water to the purge flask. Cap the purge 
flask tightly in between each rinse and after adding all the components 
into the flask.
    8.3.2 Allow the oven to equilibrate to 75 [plusmn] 2 [deg]C (167 
[plusmn] 3.6 [deg]F). Begin the sample recovery process by turning the 
toggle valve on, thus allowing a 6 L/min flow of pure nitrogen through 
the purge chamber.
    8.3.3 Stop the purge after 30 min. Immediately remove the sorbent 
tube(s) from the apparatus and cap both ends. Remove the knockout trap 
and transfer the water catch to a 10 mL volumetric flask. Rinse the trap 
with organic-free deionized water and transfer the rinse to the 
volumetric flask. Dilute to the 10 mL mark with water. Transfer the 
water sample to a sample vial and store at 4 [deg]C (39.2 [deg]F) with 
zero headspace. The analysis of the contents of the water knockout trap 
is optional for this method. If the target compounds are water soluble, 
analysis of the water is recommended; meeting the recovery efficiency 
criteria in these cases would be difficult without adding the amount 
captured in the knockout trap.

------------------------------------------------------------------------

                  10.0 Calibration and Standardization

    10.1 The analytical instrument shall be calibrated with a minimum of 
three levels of standards for each compound whose concentrations bracket 
the concentration of test compounds from the sorbent tubes. Liquid 
calibration standards shall be used for calibration in the analysis of 
the solvent extracts. The liquid calibration standards shall be prepared 
in the desorption solvent matrix. The calibration standards may be 
prepared and injected individually or as a mixture. If thermal 
desorption and focusing (onto another sorbent or cryogen focusing) are 
used, a certified gaseous mixture or a series of gaseous standards shall 
be used for calibration of the instrument. The gaseous standards shall 
be focused and analyzed in the same manner as the samples.
    10.2 The analytical system shall be certified free from contaminants 
before a calibration is performed (see Section 11.1). The calibration 
standards are used to determine the linearity of the analytical system. 
Perform an initial calibration and linearity check by analyzing the 
three calibration standards for each target compound in triplicate 
starting with the lowest level and continuing to the highest level. If 
the triplicate analyses do not agree within 5 percent of their average, 
additional analyses will be needed until the 5 percent criteria is met. 
Calculate the response factor (Equation 305-3, Section 12.4) from the 
average area counts of the injections for each concentration level. 
Average the response factors of the standards for each compound. The 
linearity of the detector is acceptable if the response factor of each 
compound at a particular concentration is within 10 percent of the 
overall mean response factor for that compound. Analyze daily a mid-
level calibration standard in duplicate and calculate a new response 
factor. Compare the daily response factor average to the average 
response factor calculated for the mid-level calibration during the 
initial linearity check; repeat the three-

[[Page 977]]

level calibration procedure if the daily average response factor differs 
from the initial linearity check mid-level response factor by more than 
10 percent. Otherwise, proceed with the sample analysis.

                        11.0 Analytical Procedure

    11.1 Water Blank Analysis. A water blank shall be analyzed daily to 
determine the cleanliness of the purge and recovery system. A water 
blank is generated by adding 60 mL of organic-free deionized water to 50 
mL of PEG in the purge chamber. Treat the blank as described in Sections 
8.3.2 and 8.3.3. The purpose of the water blank is to insure that no 
contaminants exist in the sampling and analytical apparatus which would 
interfere with the quantitation of the target compounds. If contaminants 
are present, locate the source of contamination, remove it, and repeat 
the water blank analysis.
    11.2 Sample Analysis. Sample analysis in the context of this method 
refers to techniques to remove the target compounds from the sorbent 
tubes, separate them using a chromatography technique, and quantify them 
with an appropriate detector. Two types of sample extraction techniques 
typically used for sorbents include solvent desorption or direct thermal 
desorption of test compounds to a secondary focusing unit (either 
sorbent or cryogen based). The test compounds are then typically 
transferred to a GC system for analysis. Other analytical systems may be 
used (e.g., HPLC) in lieu of GC systems as long as the recovery 
efficiency criteria of this method are met.
    11.2.1 Recover the test compounds from the sorbent tubes that 
require solvent desorption by transferring the adsorbent material to a 
sample vial containing the desorption solvent. The desorption solvent 
shall be the same as the solvent used to prepare calibration standards. 
The volume of solvent depends on the amount of adsorbed material to be 
desorbed (1.0 mL per 100 mg of adsorbent material) and also on the 
amount of test compounds present. Final volume adjustment and or 
dilution can be made so that the concentration of test compounds in the 
desorption solvent is bracketed by the concentration of the calibration 
solutions. Ultrasonicate the desorption solvent for 15 min in an ice 
bath. Allow the sample to sit for a period of time so that the adsorbent 
material can settle to the bottom of the vial. Transfer the solvent with 
a pasteur pipet (minimizing the amount of adsorbent material taken) to 
another vial and store at 4 [deg]C (39.2 [deg]F).
    11.2.2 Analyze the desorption solvent or direct thermal desorption 
tubes from each sample using the same analytical parameters used for the 
calibration standard. Calculate the total weight detected for each 
compound (Equation 305-4, Section 12.5). The slope (area/amount) and y-
intercept are calculated from the line bracketed between the two closest 
calibration points. Correct the concentration of each waste sample with 
the appropriate recovery efficiency factor and the split flow ratio (if 
used). The final concentration of each individual test compound is 
calculated by dividing the corrected measured weight for that compound 
by the weight of the original sample determined in Section 8.3.1 
(Equation 305-5, Section 12.6).
    11.2.3 Repeat the analysis for the three samples collected in 
Section 8.3. Report the corrected concentration of each of the waste 
samples, average waste concentration, and relative standard deviation 
(Equation 305-6, Section 12.7).

Method 306--Determination of Chromium Emissions From Decorative and Hard 
 Chromium Electroplating and Chromium Anodizing Operations--Isokinetic 
                                 Method

    Note: This method does not include all of the specifications (e.g., 
equipment and supplies) and procedures (e.g., sampling and analytical) 
essential to its performance. Some material is incorporated by reference 
from other methods in 40 CFR Part 60, Appendix A. Therefore, to obtain 
reliable results, persons using this method should have a thorough 
knowledge of at least Method 5.

                        1.0 Scope and Application

    1.1 Analytes.

------------------------------------------------------------------------
            Analyte                  CAS No.            Sensitivity
------------------------------------------------------------------------
Chromium......................  7440-47-3........  See Sec. 13.2.
------------------------------------------------------------------------

    1.2 Applicability. This method applies to the determination of 
chromium (Cr) in emissions from decorative and hard chrome 
electroplating facilities, chromium anodizing operations, and continuous 
chromium plating operations at iron and steel facilities.
    1.3 Data Quality Objectives. [Reserved]

                          2.0 Summary of Method

    2.1 Sampling. An emission sample is extracted isokinetically from 
the source using an unheated Method 5 sampling train (40 CFR Part 60, 
Appendix A), with a glass nozzle and probe liner, but with the filter 
omitted. The sample time shall be at least two hours. The Cr emissions 
are collected in an alkaline solution containing 0.1 N sodium hydroxide 
(NaOH) or 0.1 N sodium bicarbonate (NaHCO3). The collected 
samples are recovered using an alkaline solution and are then 
transported to the laboratory for analysis.
    2.2 Analysis.
    2.2.1 Total chromium samples with high chromium concentrations 
([ge]35 [mu]g/L) may be analyzed using inductively coupled plasma 
emission spectrometry (ICP) at 267.72 nm.
    Note: The ICP analysis is applicable for this method only when the 
solution analyzed has a Cr concentration greater than or equal to 35 
[mu]g/L or five times the method detection

[[Page 983]]

limit as determined according to Appendix B in 40 CFR Part 136.
    2.2.2 Alternatively, when lower total chromium concentrations (<35 
[mu]g/L) are encountered, a portion of the alkaline sample solution may 
be digested with nitric acid and analyzed by graphite furnace atomic 
absorption spectroscopy (GFAAS) at 357.9 nm.
    2.2.3 If it is desirable to determine hexavalent chromium 
(Cr+6) emissions, the samples may be analyzed using an ion 
chromatograph equipped with a post-column reactor (IC/PCR) and a visible 
wavelength detector. To increase sensitivity for trace levels of 
Cr+6, a preconcentration system may be used in conjunction 
with the IC/PCR.

                             3.0 Definitions

    3.1 Total Chromium--measured chromium content that includes both 
major chromium oxidation states (Cr+3, Cr+3).
    3.2 May--Implies an optional operation.
    3.3 Digestion--The analytical operation involving the complete (or 
nearly complete) dissolution of the sample in order to ensure the 
complete solubilization of the element (analyte) to be measured.
    3.4 Interferences--Physical, chemical, or spectral phenomena that 
may produce a high or low bias in the analytical result.
    3.5 Analytical System--All components of the analytical process 
including the sample digestion and measurement apparatus.
    3.6 Sample Recovery--The quantitative transfer of sample from the 
collection apparatus to the sample preparation (digestion, etc.) 
apparatus. This term should not be confused with analytical recovery.
    3.7 Matrix Modifier--A chemical modification to the sample during 
GFAAS determinations to ensure that the analyte is not lost during the 
measurement process (prior to the atomization stage)
    3.8 Calibration Reference Standards--Quality control standards used 
to check the accuracy of the instrument calibration curve prior to 
sample analysis.
    3.9 Continuing Check Standard--Quality control standards used to 
verify that unacceptable drift in the measurement system has not 
occurred.
    3.10 Calibration Blank--A blank used to verify that there has been 
no unacceptable shift in the baseline either immediately following 
calibration or during the course of the analytical measurement.
    3.11 Interference Check--An analytical/measurement operation that 
ascertains whether a measurable interference in the sample exists.
    3.12 Interelement Correction Factors--Factors used to correct for 
interfering elements that produce a false signal (high bias).
    3.13 Duplicate Sample Analysis--Either the repeat measurement of a 
single solution or the measurement of duplicate preparations of the same 
sample. It is important to be aware of which approach is required for a 
particular type of measurement. For example, no digestion is required 
for the ICP determination and the duplicate instrument measurement is 
therefore adequate whereas duplicate digestion/instrument measurements 
are required for GFAAS.
    3.14 Matrix Spiking--Analytical spikes that have been added to the 
actual sample matrix either before (Section 9.2.5.2) or after (Section 
9.1.6). Spikes added to the sample prior to a preparation technique 
(e.g., digestion) allow for the assessment of an overall method accuracy 
while those added after only provide for the measurement accuracy 
determination.

                            4.0 Interferences

    4.1 ICP Interferences.
    4.1.1 ICP Spectral Interferences. Spectral interferences are caused 
by: overlap of a spectral line from another element; unresolved overlap 
of molecular band spectra; background contribution from continuous or 
recombination phenomena; and, stray light from the line emission of 
high-concentrated elements. Spectral overlap may be compensated for by 
correcting the raw data with a computer and measuring the interfering 
element. At the 267.72 nm Cr analytical wavelength, iron, manganese, and 
uranium are potential interfering elements. Background and stray light 
interferences can usually be compensated for by a background correction 
adjacent to the analytical line. Unresolved overlap requires the 
selection of an alternative chromium wavelength. Consult the instrument 
manufacturer's operation manual for interference correction procedures.
    4.1.2 ICP Physical Interferences. High levels of dissolved solids in 
the samples may cause significant inaccuracies due to salt buildup at 
the nebulizer and torch tips. This problem can be controlled by diluting 
the sample or by extending the rinse times between sample analyses. 
Standards shall be prepared in the same solution matrix as the samples 
(i.e., 0.1 N NaOH or 0.1 N NaHCO3).
    4.1.3 ICP Chemical Interferences. These include molecular compound 
formation, ionization effects and solute vaporization effects, and are 
usually not significant in the ICP procedure, especially if the 
standards and samples are matrix matched.
    4.2 GFAAS Interferences.
    4.2.1 GFAAS Chemical Interferences. Low concentrations of calcium 
and/or phosphate may cause interferences; at concentrations above 200 
[mu]g/L, calcium's effect is constant and eliminates the effect of 
phosphate. Calcium nitrate is therefore added to the concentrated 
analyte to ensure a known constant effect. Other matrix modifiers 
recommended by the instrument manufacturer may also be considered.

[[Page 984]]

    4.2.2 GFAAS Cyanide Band Interferences. Nitrogen should not be used 
as the purge gas due to cyanide band interference.
    4.2.3 GFAAS Spectral Interferences. Background correction may be 
required because of possible significant levels of nonspecific 
absorption and scattering at the 357.9 nm analytical wavelength.
    4.2.4 GFAAS Background Interferences. Zeeman or Smith-Hieftje 
background correction is recommended for interferences resulting from 
high levels of dissolved solids in the alkaline impinger solutions.
    4.3 IC/PCR Interferences.
    4.3.1 IC/PCR Chemical Interferences. Components in the sample matrix 
may cause Cr+6 to convert to trivalent chromium 
(Cr+3) or cause Cr+3 to convert to 
Cr+6. The chromatographic separation of Cr+6 using 
ion chromatography reduces the potential for other metals to interfere 
with the post column reaction. For the IC/PCR analysis, only compounds 
that coelute with Cr+6 and affect the diphenylcarbazide 
reaction will cause interference.
    4.3.2 IC/PCR Background Interferences. Periodic analyses of reagent 
water blanks are used to demonstrate that the analytical system is 
essentially free of contamination. Sample cross-contamination can occur 
when high-level and low-level samples or standards are analyzed 
alternately and can be eliminated by thorough purging of the sample 
loop. Purging of the sample can easily be achieved by increasing the 
injection volume to ten times the size of the sample loop.

                               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 to establish appropriate safety and health practices and to 
determine the applicability of regulatory limitations prior to 
performing this test method.
    5.2 Hexavalent chromium compounds have been listed as carcinogens 
although chromium (III) compounds show little or no toxicity. Chromium 
can be a skin and respiratory irritant.

    8.0 Sample Collection, Preservation, Holding Times, Storage, and 
                                Transport

    Note: Prior to sample collection, consideration should be given to 
the type of analysis (Cr+\6\ or total Cr) that will be 
performed. Which analysis option(s) will be performed will determine 
which sample recovery and storage procedures will be required to process 
the sample (See Figures 306-3 and 306-4).
    8.1 Sample Collection. Same as Method 5 (40 CFR part 60, Appendix 
A), with the following exceptions.
    8.1.1 Omit the particulate filter and filter holder from the 
sampling train. Use a glass nozzle and probe liner instead of stainless 
steel. Do not heat the probe. Place 100 mL of 0.1 N NaOH or 0.1 N 
NaHCO3 in each of the first two impingers, and record the 
data for each run on a data sheet such as shown in Figure 306-2.
    8.1.2 Clean all glassware prior to sampling in hot soapy water 
designed for laboratory cleaning of glassware. Next, rinse the glassware 
three times with tap water, followed by three additional rinses with 
reagent water. Then soak the glassware in 10% (v/v) HNO3 
solution for a minimum of 4 hours, rinse three times with reagent water, 
and allow to air dry. Cover all glassware openings where contamination 
can occur with Parafilm, or equivalent, until the sampling train is 
assembled for sampling.
    8.1.3 Train Operation. Follow the basic procedures outlined in 
Method 5 in conjunction with the following instructions. Train sampling 
rate shall not exceed 0.030 m\3\/min (1.0 cfm) during a run.

or the Cr+\6\ analysis. If both analyses (Cr and 
Cr+\6\) are to be conducted on the samples, collect separate 
reagent blanks for each analysis.
    Note: Since particulate matter is not usually present at chromium 
electroplating and/or chromium anodizing operations, it is not necessary 
to filter the Cr+\6\ samples unless there is observed 
sediment in the collected solutions. If it is necessary to filter the 
Cr+\6\ solutions, please refer to Method 0061, Determination 
of Hexavalent Chromium Emissions From Stationary Sources, Section 7.4, 
Sample Preparation in SW-846 (see Reference 1).

first, second, and third impingers and quantitatively transfer into a 
labeled sample container.
    8.2.5.2 Use approximately 200 to 300 mL of the 0.1 N NaOH or 0.1 N 
NaHCO3 absorbing solution to rinse the probe nozzle, probe 
liner, three impingers, and connecting glassware; add this rinse to 
Container No. 1.
    8.2.6 Cr+\6\ Sample Option.
    8.2.6.1 Container No. 1. Measure and record the pH of the absorbing 
solution contained in the first impinger at the end of the sampling run 
using a pH indicator strip. The pH of the solution must be [ge]8.5 for 
NaOH and [ge]8.0 for NaHCO3. If it is not, discard the 
collected sample, increase the normality of the NaOH or 
NaHCO3 impinger absorbing solution to 0.5 N or to a solution 
normality approved by the Administrator and collect another air emission 
sample.
    8.2.6.2 After determining the pH of the first impinger solution, 
combine and measure the volume of the liquid in the first, second, and 
third impingers and quantitatively transfer into the labeled sample 
container.

reference standard using the same alkaline matrix as the calibration 
standards; it should be at least 10 times the instrumental detection 
limit.
    9.1.1.1 This reference standard must be prepared from a different Cr 
stock solution source than that used for preparation of the calibration 
curve standards.
    9.1.1.2 Prior to sample analysis, analyze at least one reference 
standard.
    9.1.1.3 The calibration reference standard must be measured within 
10 percent of it's true value for the curve to be considered valid.
    9.1.1.4 The curve must be validated before sample analyses are 
performed.
    9.1.2 ICP Continuing Check Standard.
    9.1.2.1 Perform analysis of the check standard with the field 
samples as described in Section 11.2 (at least after every 10 samples, 
and at the end of the analytical run).
    9.1.2.2 The check standard can either be the mid-range calibration 
standard or the reference standard. The results of the check standard 
shall agree within 10 percent of the expected value; if not, terminate 
the analyses, correct the problem, recalibrate the instrument, and rerun 
all samples analyzed subsequent to the last acceptable check standard 
analysis.
    9.1.3 ICP Calibration Blank.
    9.1.3.1 Perform analysis of the calibration blank with the field 
samples as described in Section 11.2 (at least after every 10 samples, 
and at the end of the analytical run).
    9.1.3.2 The results of the calibration blank shall agree within 
three standard deviations of the mean blank value. If not, analyze the 
calibration blank two more times and average the results. If the average 
is not within three standard deviations of the background mean, 
terminate the analyses, correct the problem, recalibrate, and reanalyze 
all samples analyzed subsequent to the last acceptable calibration blank 
analysis.
    9.1.4 ICP Interference Check. Prepare an interference check solution 
that contains known concentrations of interfering elements that will 
provide an adequate test of the correction factors in the event of 
potential spectral interferences.
    9.1.4.1 Two potential interferences, iron and manganese, may be 
prepared as 1000 [mu]g/mL and 200 [mu]g/mL solutions, respectively. The 
solutions should be prepared in dilute HNO3 (1-5 percent). 
Particular care must be used to ensure that the solutions and/or salts 
used to prepare the solutions are of ICP grade purity (i.e., that no 
measurable Cr contamination exists in the salts/solutions). Commercially 
prepared interfering element check standards are available.
    9.1.4.2 Verify the interelement correction factors every three 
months by analyzing the interference check solution. The correction 
factors are calculated according to the instrument manufacturer's 
directions. If the interelement correction factors are used properly, no 
false Cr should be detected.
    9.1.4.3 Negative results with an absolute value greater than three 
(3) times the detection limit are usually the results of the background 
correction position being set incorrectly. Scan the spectral region to 
ensure that the correction position has not been placed on an 
interfering peak.
    9.1.5 ICP Duplicate Sample Analysis. Perform one duplicate sample 
analysis for each compliance sample batch (3 runs).
    9.1.5.1 As there is no sample preparation required for the ICP 
analysis, a duplicate analysis is defined as a repeat analysis of one of 
the field samples. The selected sample shall be analyzed using the same 
procedures that were used to analyze the original sample.
    9.1.5.2 Duplicate sample analyses shall agree within 10 percent of 
the original measurement value.
    9.1.5.3 Report the original analysis value for the sample and report 
the duplicate analysis value as the QC check value. If agreement is not 
achieved, perform the duplicate analysis again. If agreement is not 
achieved the second time, perform corrective action to identify and 
correct the problem before analyzing the sample for a third time.
    9.1.6 ICP Matrix Spiking. Spiked samples shall be prepared and 
analyzed daily to ensure that there are no matrix effects, that samples 
and standards have been matrix-matched, and that the laboratory 
equipment is operating properly.

[[Page 988]]

    9.1.6.1 Spiked sample recovery analyses should indicate a recovery 
for the Cr spike of between 75 and 125 percent.
    9.1.6.2 Cr levels in the spiked sample should provide final solution 
concentrations that are within the linear portion of the calibration 
curve, as well as, at a concentration level at least: equal to that of 
the original sample; and, ten (10) times the detection limit.
    9.1.6.3 If the spiked sample concentration meets the stated criteria 
but exceeds the linear calibration range, the spiked sample must be 
diluted with the field absorbing solution.
    9.1.6.4 If the recoveries for the Cr spiked samples do not meet the 
specified criteria, perform corrective action to identify and correct 
the problem prior to reanalyzing the samples.
    9.1.7 ICP Field Reagent Blank.

auditor. If the specified range is not met, reanalyze the compliance and 
audit samples, and include initial and reanalysis values in the test 
report.
    9.1.9.4 Failure to meet the specified range may require retests 
unless the audit problems are resolved. However, if the audit results do 
not affect the compliance or noncompliance status of the affected 
facility, the Administrator may waive the reanalysis requirement, 
further audits, or retests and accept the results of the compliance

                       11.0 Analytical Procedures

    Note: The method determines the chromium concentration in [mu]g Cr/
mL. It is important that the analyst measure the field sample volume 
prior to analyzing the sample. This will allow for conversion of [mu]g 
Cr/mL to [mu]g Cr/sample.

analyzed has a Cr concentration greater than 35 [mu]g/L or five times 
the method detection limit as determined according to Appendix B in 40 
CFR Part 136 or by other commonly accepted analytical procedures.

establishing the calibration curve. For the calibration blank, use 
either 0.1 N NaOH or 0.1 N NaHCO3, whichever is used for the 
impinger absorbing solution. The calibration blank can be prepared fresh 
in the laboratory; it does not have to be prepared from the same batch 
of solution that was used in the field. A sufficient quantity should be 
prepared to flush the system between standards and samples.
    11.2.2.2 Field Reagent Blank. The field reagent blank is collected 
in the field during the testing program. The field reagent blank 
(Section 8.2.4) is an aliquot of the absorbing solution prepared in 
Section 7.1.2. The reagent blank is used to assess possible 
contamination resulting from sample processing.
    11.2.3 ICP Instrument Adjustment.
    11.2.3.1 Adjust the ICP instrument for proper operating parameters 
including wavelength, background correction settings (if necessary), and 
interfering element correction settings (if necessary).
    11.2.3.2 The instrument must be allowed to become thermally stable 
before beginning measurements (usually requiring at least 30

[[Page 992]]

min of operation prior to calibration). During this warmup period, the 
optical calibration and torch position optimization may be performed 
(consult the operator's manual).
    11.2.4 ICP Instrument Calibration.
    11.2.4.1 Calibrate the instrument according to the instrument 
manufacturer's recommended procedures, and the procedures specified in 
Section 10.2.
    11.2.4.2 Prior to analyzing the field samples, reanalyze the highest 
calibration standard as if it were a sample.
    11.2.4.3 Concentration values obtained should not deviate from the 
actual values or from the established control limits by more than 5 
percent, whichever is lower (see Sections 9.1 and 10.2).
    11.2.4.4 If they do, follow the recommendations of the instrument 
manufacturer to correct the problem.
    11.2.5 ICP Operational Quality Control Procedures.
    11.2.5.1 Flush the system with the calibration blank solution for at 
least 1 min before the analysis of each sample or standard.
    11.2.5.2 Analyze the continuing check standard and the calibration 
blank after each batch of 10 samples.
    11.2.5.3 Use the average intensity of multiple exposures for both 
standardization and sample analysis to reduce random error.
    11.2.6 ICP Sample Dilution.
    11.2.6.1 Dilute and reanalyze samples that are more concentrated 
than the linear calibration limit or use an alternate, less sensitive Cr 
wavelength for which quality control data have already been established.
    11.2.6.2 When dilutions are performed, the appropriate factors must 
be applied to sample measurement results.
    11.2.7 Reporting Analytical Results. All analytical results should 
be reported in [mu]g Cr/mL using three significant figures. Field sample 
volumes (mL) must be reported also.
    11.3 GFAAS Sample Preparation.
    11.3.1 GFAAS Acid Digestion. An acid digestion of the alkaline 
impinger solution is required for the GFAAS analysis.
    11.3.1.1 In a beaker, add 10 mL of concentrated HNO3 to a 
100 mL sample aliquot that has been well mixed. Cover the beaker with a 
watch glass. Place the beaker on a hot plate and reflux the sample to 
near dryness. Add another 5 mL of concentrated HNO3 to 
complete the digestion. Again, carefully reflux the sample volume to 
near dryness. Rinse the beaker walls and watch glass with reagent water.
    11.3.1.2 The final concentration of HNO3 in the solution 
should be 1 percent (v/v).
    11.3.1.3 Transfer the digested sample to a 50-mL volumetric flask. 
Add 0.5 mL of concentrated HNO3 and 1 mL of the 10 [mu]g/mL 
of Ca(NO3)2. Dilute to 50 mL with reagent water.
    11.3.2 HNO3 Concentration. A different final volume may 
be used based on the expected Cr concentration, but the HNO3 
concentration must be maintained at 1 percent (v/v).
    11.4 GFAAS Sample Analysis.
    11.4.1 The GFAAS analysis is applicable for the determination of 
total chromium only.
    11.4.2 GFAAS Blanks. Two types of blanks are required for the GFAAS 
analysis.
    11.4.2.1 Calibration Blank. The 1.0 percent HNO3 is the 
calibration blank which is used in establishing the calibration curve.
    11.4.2.2 Field Reagent Blank. An aliquot of the 0.1 N NaOH solution 
or the 0.1 N NaHCO3 prepared in Section 7.1.2 is collected 
for the field reagent blank. The field reagent blank is used to assess 
possible contamination resulting from processing the sample.
    11.4.2.2.1 The reagent blank must be subjected to the entire series 
of sample preparation and analytical procedures, including the acid 
digestion.
    11.4.2.2.2 The reagent blank's final solution must contain the same 
acid concentration as the sample solutions.
    11.4.3 GFAAS Instrument Adjustment.
    11.4.3.1 The 357.9 nm wavelength line shall be used.
    11.4.3.2 Follow the manufacturer's instructions for all other 
spectrophotometer operating parameters.
    11.4.4 Furnace Operational Parameters. Parameters suggested by the 
manufacturer should be employed as guidelines.
    11.4.4.1 Temperature-sensing mechanisms and temperature controllers 
can vary between instruments and/or with time; the validity of the 
furnace operating parameters must be periodically confirmed by 
systematically altering the furnace parameters while analyzing a 
standard. In this manner, losses of analyte due to higher-than-necessary 
temperature settings or losses in sensitivity due to less than optimum 
settings can be minimized.
    11.4.4.2 Similar verification of furnace operating parameters may be 
required for complex sample matrices (consult instrument manual for 
additional information). Calibrate the GFAAS system following the 
procedures specified in Section 10.3.
    11.4.5 GFAAS Operational Quality Control Procedures.
    11.4.5.1 Introduce a measured aliquot of digested sample into the 
furnace and atomize.
    11.4.5.2 If the measured concentration exceeds the calibration 
range, the sample should be diluted with the calibration blank solution 
(1.0 percent HNO3) and reanalyzed.
    11.4.5.3 Consult the operator's manual for suggested injection 
volumes. The use of multiple injections can improve accuracy and assist 
in detecting furnace pipetting errors.
    11.4.5.4 Analyze a minimum of one matrix-matched reagent blank per 
sample batch

[[Page 993]]

to determine if contamination or any memory effects are occurring.
    11.4.5.5 Analyze a calibration blank and a continuing check standard 
after approximately every batch of 10 sample injections.
    11.4.6 GFAAS Sample Dilution.
    11.4.6.1 Dilute and reanalyze samples that are more concentrated 
than the instrument calibration range.
    11.4.6.2 If dilutions are performed, the appropriate factors must be 
applied to sample measurement results.
    11.4.7 Reporting Analytical Results.
    11.4.7.1 Calculate the Cr concentrations by the method of standard 
additions (see operator's manual) or, from direct calibration. All 
dilution and/or concentration factors must be used when calculating the 
results.
    11.4.7.2 Analytical results should be reported in [mu]g Cr/mL using 
three significant figures. Field sample volumes (mL) must be reported 
also.
    11.5 IC/PCR Sample Preparation.
    11.5.1 Sample pH. Measure and record the sample pH prior to 
analysis.
    11.5.2 Sample Filtration. Prior to preconcentration and/or analysis, 
filter all field samples through a 0.45-[mu]m filter. The filtration 
step should be conducted just prior to sample injection/analysis.
    11.5.2.1 Use a portion of the sample to rinse the syringe filtration 
unit and acetate filter and then collect the required volume of 
filtrate.
    11.5.2.2 Retain the filter if total Cr is to be determined also.
    11.5.3 Sample Preconcentration (older instruments).
    11.5.3.1 For older instruments, a preconcentration system may be 
used in conjunction with the IC/PCR to increase sensitivity for trace 
levels of Cr+6.
    11.5.3.2 The preconcentration is accomplished by selectively 
retaining the analyte on a solid absorbent, followed by removal of the 
analyte from the absorbent (consult instrument manual).
    11.5.3.3 For a manual system, position the injection valve so that 
the eluent displaces the concentrated Cr+\6\ sample, 
transferring it from the preconcentration column and onto the IC anion 
separation column.
    11.6 IC/PCR Sample Analyses.
    11.6.1 The IC/PCR analysis is applicable for hexavalent chromium 
measurements only.
    11.6.2 IC/PCR Blanks. Two types of blanks are required for the IC/
PCR analysis.
    11.6.2.1 Calibration Blank. The calibration blank is used in 
establishing the analytical curve. For the calibration blank, use either 
0.1 N NaOH or 0.1 N NaHCO3, whichever is used for the 
impinger solution. The calibration blank can be prepared fresh in the 
laboratory; it does not have to be prepared from the same batch of 
absorbing solution that is used in the field.
    11.6.2.2 Field Reagent Blank. An aliquot of the 0.1 N NaOH solution 
or the 0.1 N NaHCO3 solution prepared in Section 7.1.2 is 
collected for the field reagent blank. The field reagent blank is used 
to assess possible contamination resulting from processing the sample.
    11.6.3 Stabilized Baseline. Prior to sample analysis, establish a 
stable baseline with the detector set at the required attenuation by 
setting the eluent and post-column reagent flow rates according to the 
manufacturers recommendations.
    Note: As long as the ratio of eluent flow rate to PCR flow rate 
remains constant, the standard curve should remain linear. Inject a 
sample of reagent water to ensure that no Cr+6 appears in the 
water blank.
    11.6.4 Sample Injection Loop. Size of injection loop is based on 
standard/sample concentrations and the selected attenuator setting.
    11.6.4.1 A 50-[mu]L loop is normally sufficient for most higher 
concentrations.
    11.6.4.2 The sample volume used to load the injection loop should be 
at least 10 times the loop size so that all tubing in contact with the 
sample is thoroughly flushed with the new sample to prevent cross 
contamination.
    11.6.5 IC/PCR Instrument Calibration.
    11.6.5.1 First, inject the calibration standards prepared, as 
described in Section 7.3.8 to correspond to the appropriate 
concentration range, starting with the lowest standard first.
    11.6.5.2 Check the performance of the instrument and verify the 
calibration using data gathered from analyses of laboratory blanks, 
calibration standards, and a quality control sample.
    11.6.5.3 Verify the calibration by analyzing a calibration reference 
standard. If the measured concentration exceeds the established value by 
more than 10 percent, perform a second analysis. If the measured 
concentration still exceeds the established value by more than 10 
percent, terminate the analysis until the problem can be identified and 
corrected.
    11.6.6 IC/PCR Instrument Operation.
    11.6.6.1 Inject the calibration reference standard (as described in 
Section 9.3.1), followed by the field reagent blank (Section 8.2.4), and 
the field samples.
    11.6.6.1.1 Standards (and QC standards) and samples are injected 
into the sample loop of the desired size (use a larger size loop for 
greater sensitivity). The Cr+6 is collected on the resin bed 
of the column.
    11.6.6.1.2 After separation from other sample components, the 
Cr+6 forms a specific complex in the post-column reactor with 
the DPC reaction solution, and the complex is detected by visible 
absorbance at a maximum wavelength of 540 nm.

[[Page 994]]

    11.6.6.1.3 The amount of absorbance measured is proportional to the 
concentration of the Cr+6 complex formed.
    11.6.6.1.4 The IC retention time and the absorbance of the 
Cr+6 complex with known Cr+6 standards analyzed 
under identical conditions must be compared to provide both qualitative 
and quantitative analyses.
    11.6.6.1.5 If a sample peak appears near the expected retention time 
of the Cr+6 ion, spike the sample according to Section 9.3.4 
to verify peak identity.
    11.6.7 IC/PCR Operational Quality Control Procedures.
    11.6.7.1 Samples should be at a pH [ge]8.5 for NaOH and [ge]8.0 if 
using NaHCO3; document any discrepancies.
    11.6.7.2 Refrigerated samples should be allowed to equilibrate to 
ambient temperature prior to preparation and analysis.
    11.6.7.3 Repeat the injection of the calibration standards at the 
end of the analytical run to assess instrument drift. Measure areas or 
heights of the Cr+6/DPC complex chromatogram peaks.
    11.6.7.4 To ensure the precision of the sample injection (manual or 
autosampler), the response for the second set of injected standards must 
be within 10 percent of the average response.
    11.6.7.5 If the 10 percent criteria duplicate injection cannot be 
achieved, identify the source of the problem and rerun the calibration 
standards.
    11.6.7.6 Use peak areas or peak heights from the injections of 
calibration standards to generate a linear calibration curve. From the 
calibration curve, determine the concentrations of the field samples.
    11.6.8 IC/PCR Sample Dilution.
    11.6.8.1 Samples having concentrations higher than the established 
calibration range must be diluted into the calibration range and re-
analyzed.
    11.6.8.2 If dilutions are performed, the appropriate factors must be 
applied to sample measurement results.
    11.6.9 Reporting Analytical Results. Results should be reported in 
[mu]g Cr+6/mL using three significant figures. Field sample 
volumes (mL) must be reported also.

                   12.0 Data Analysis and Calculations

    12.1 Pretest Calculations.
    12.1.1 Pretest Protocol (Site Test Plan).
    12.1.1.1 The pretest protocol should define and address the test 
data quality objectives (DQOs), with all assumptions, that will be 
required by the end user (enforcement authority); what data are needed? 
why are the data needed? how will the data be used? what are method 
detection limits? and what are estimated target analyte levels for the 
following test parameters.
    12.1.1.1.1 Estimated source concentration for total chromium and/or 
Cr+6.
    12.1.1.1.2 Estimated minimum sampling time and/or volume required to 
meet method detection limit requirements (Appendix B 40 CFR Part 136) 
for measurement of total chromium and/or Cr+6.
    12.1.1.1.3 Demonstrate that planned sampling parameters will meet 
DQOs. The protocol must demonstrate that the planned sampling parameters 
calculated by the tester will meet the needs of the source and the 
enforcement authority.
    12.1.1.2 The pre-test protocol should include information on 
equipment, logistics, personnel, process operation, and other resources 
necessary for an efficient and coordinated test.
    12.1.1.3 At a minimum, the pre-test protocol should identify and be 
approved by the source, the tester, the analytical laboratory, and the 
regulatory enforcement authority. The tester should not proceed with the 
compliance testing before obtaining approval from the enforcement 
authority.
    12.1.2 Post Test Calculations.
    12.1.2.1 Perform the calculations, retaining one extra decimal 
figure beyond that of the acquired data. Round off figures after final 
calculations.
    12.1.2.2 Nomenclature.

          to standard conditions, mg/dscm.

    12.1.2.9 Isokinetic Variation, Acceptable Results. Same as Method 5.

                         13.0 Method Performance

    13.1 Range. The recommended working range for all of the three 
analytical techniques starts at five times the analytical detection 
limit (see also Section 13.2.2). The upper limit of all three techniques 
can be extended indefinitely by appropriate dilution.
    13.2 Sensitivity.
    13.2.1 Analytical Sensitivity. The estimated instrumental detection 
limits listed are provided as a guide for an instrumental limit. The 
actual method detection limits are sample and instrument dependent and 
may vary as the sample matrix varies.
    13.2.1.2 ICP Analytical Sensitivity. The minimum estimated detection 
limits for ICP, as reported in Method 6010A and the recently revised 
Method 6010B of SW-846 (Reference 1), are 7.0 [mu]g Cr/L and 4.7 [mu]g 
Cr/L, respectively.
    13.2.1.3 GFAAS Analytical Sensitivity. The minimum estimated 
detection limit for GFAAS, as reported in Methods 7000A and 7191 of SW-
846 (Reference 1), is 1 [mu]g Cr/L.
    13.2.1.4 IC/PCR Analytical Sensitivity. The minimum detection limit 
for IC/PCR with a preconcentrator, as reported in Methods 0061 and 7199 
of SW-846 (Reference 1), is 0.05 [mu]g Cr\+6\/L.
    1.3.2.1.5 Determination of Detection Limits. The laboratory 
performing the Cr\+6\ measurements must determine the method detection 
limit on a quarterly basis using a suitable procedure such as that found 
in 40 CFR, Part 136, Appendix B. The determination should be made on 
samples in the appropriate alkaline matrix. Normally this involves the 
preparation (if applicable) and consecutive measurement of seven (7) 
separate aliquots of a sample with a concentration <5 times the expected 
detection limit. The detection limit is 3.14 times the standard 
deviation of these results.

[[Page 996]]

    13.2.2 In-stack Sensitivity. The in-stack sensitivity depends upon 
the analytical detection limit, the volume of stack gas sampled, the 
total volume of the impinger absorbing solution plus the rinses, and, in 
some cases, dilution or concentration factors from sample preparation. 
Using the analytical detection limits given in Sections 13.2.1.1, 
13.2.1.2, and 13.2.1.3; a stack gas sample volume of 1.7 dscm; a total 
liquid sample volume of 500 mL; and the digestion concentration factor 
of 1/2 for the GFAAS analysis; the corresponding in-stack detection 
limits are 0.0014 mg Cr/dscm to 0.0021 mg Cr/dscm for ICP, 0.00015 mg 
Cr/dscm for GFAAS, and 0.000015 mg Cr\+6\/dscm for IC/PCR with 
preconcentration.

    Note: It is recommended that the concentration of Cr in the 
analytical solutions be at least five times the analytical detection 
limit to optimize sensitivity in the analyses. Using this guideline and 
the same assumptions for impinger sample volume, stack gas sample 
volume, and the digestion concentration factor for the GFAAS analysis 
(500 mL,1.7 dscm, and 1/2, respectively), the recommended minimum stack 
concentrations for optimum sensitivity are 0.0068 mg Cr/dscm to 0.0103 
mg Cr/dscm for ICP, 0.00074 mg Cr/dscm for GFAAS, and 0.000074 mg 
Cr\+6\/dscm for IC/PCR with preconcentration. If required, the in-stack 
detection limits can be improved by either increasing the stack gas 
sample volume, further reducing the volume of the digested sample for 
GFAAS, improving the analytical detection limits, or any combination of 
the three.

    13.3 Precision.
    13.3.1 The following precision data have been reported for the three 
analytical methods. In each case, when the sampling precision is 
combined with the reported analytical precision, the resulting overall 
precision may decrease.
    13.3.2 Bias data is also reported for GFAAS.
    13.4 ICP Precision.
    13.4.1 As reported in Method 6010B of SW-846 (Reference 1), in an 
EPA round-robin Phase 1 study, seven laboratories applied the ICP 
technique to acid/distilled water matrices that had been spiked with 
various metal concentrates. For true values of 10, 50, and 150 [mu]g Cr/
L; the mean reported values were 10, 50, and 149 [mu]g Cr/L; and the 
mean percent relative standard deviations were 18, 3.3, and 3.8 percent, 
respectively.
    13.4.2 In another multi laboratory study cited in Method 6010B, a 
mean relative standard of 8.2 percent was reported for an aqueous sample 
concentration of approximately 3750 [mu]g Cr/L.
    13.5 GFAAS Precision. As reported in Method 7191 of SW-846 
(Reference 1), in a single laboratory (EMSL), using Cincinnati, Ohio tap 
water spiked at concentrations of 19, 48, and 77 [mu]g Cr/L, the 
standard deviations were [plusmn]0.1, [plusmn]0.2, and [plusmn]0.8, 
respectively. Recoveries at these levels were 97 percent, 101 percent, 
and 102 percent, respectively.
    13.6 IC/PCR Precision. As reported in Methods 0061 and 7199 of SW-
846 (Reference 1), the precision of IC/PCR with sample preconcentration 
is 5 to 10 percent. The overall precision for sewage sludge incinerators 
emitting 120 ng/dscm of Cr+\6\ and 3.5 [mu]g/dscm of total Cr 
was 25 percent and 9 percent, respectively; and for hazardous waste 
incinerators emitting 300 ng/dscm of C+\6\ the precision was 
20 percent.

                        14.0 Pollution Prevention

    14.1 The only materials used in this method that could be considered 
pollutants are the chromium standards used for instrument calibration 
and acids used in the cleaning of the collection and measurement 
containers/labware, in the preparation of standards, and in the acid 
digestion of samples. Both reagents can be stored in the same waste 
container.
    14.2 Cleaning solutions containing acids should be prepared in 
volumes consistent with use to minimize the disposal of excessive 
volumes of acid.
    14.3 To the extent possible, the containers/vessels used to collect 
and prepare samples should be cleaned and reused to minimize the 
generation of solid waste.

                          15.0 Waste Management

    15.1 It is the responsibility of the laboratory and the sampling 
team to comply with all federal, state, and local regulations governing 
waste management, particularly the discharge regulations, hazardous 
waste identification rules, and land disposal restrictions; and to 
protect the air, water, and land by minimizing and controlling all 
releases from field operations.

Management Manual for Laboratory Personnel and Less is Better--

American Chemical Society's Department of Government Relations and 
Science Policy, 1155 16th Street NW, Washington, DC 20036.

  Method 306A--Determination of Chromium Emissions From Decorative and 
     Hard Chromium Electroplating and Chromium Anodizing Operations

    Note: This method does not include all of the specifications (e.g., 
equipment and supplies) and procedures (e.g., sampling and analytical) 
essential to its performance. Some material is incorporated by reference 
from other methods in 40 CFR Part 60, Appendix A and in this part. 
Therefore, to obtain reliable results, persons using this method should 
have a thorough knowledge of at least Methods 5 and 306.

                        1.0 Scope and Application

    1.1 Analyte. Chromium. CAS Number (7440-47-3).
    1.2 Applicability.

[[Page 999]]

    1.2.1 This method applies to the determination of chromium (Cr) in 
emissions from decorative and hard chromium electroplating facilities, 
chromium anodizing operations, and continuous chromium plating at iron 
and steel facilities. The method is less expensive and less complex to 
conduct than Method 306. Correctly applied, the precision and bias of 
the sample results should be comparable to those obtained with the 
isokinetic Method 306. This method is applicable for the determination 
of air emissions under nominal ambient moisture, temperature, and 
pressure conditions.
    1.2.2 The method is also applicable to electroplating and anodizing 
sources controlled by wet scrubbers.
    1.3 Data Quality Objectives.
    1.3.1 Pretest Protocol.
    1.3.1.1 The pretest protocol should define and address the test data 
quality objectives (DQOs), with all assumptions, that will be required 
by the end user (enforcement authority); what data are needed? why are 
the data needed? how will data be used? what are method detection 
limits? and what are estimated target analyte levels for the following 
test parameters.
    1.3.1.1.1 Estimated source concentration for total chromium and/or 
Cr\+6\.
    1.3.1.1.2 Estimated minimum sampling time and/or volume required to 
meet method detection limit requirements (Appendix B 40 CFR Part 136) 
for measurement of total chromium and/or Cr\+6\.
    1.3.1.1.3 Demonstrate that planned sampling parameters will meet 
DQOs. The protocol must demonstrate that the planned sampling parameters 
calculated by the tester will meet the needs of the source and the 
enforcement authority.
    1.3.1.2 The pre-test protocol should include information on 
equipment, logistics, personnel, process operation, and other resources 
necessary for an efficient and coordinated performance test.
    1.3.1.3 At a minimum, the pre-test protocol should identify and be 
approved by the source, the tester, the analytical laboratory, and the 
regulatory enforcement authority. The tester should not proceed with the 
compliance testing before obtaining approval from the enforcement 
authority.

                          2.0 Summary of Method

    2.1 Sampling.
    2.1.1 An emission sample is extracted from the source at a constant 
sampling rate determined by a critical orifice and collected in a 
sampling train composed of a probe and impingers. The proportional 
sampling time at the cross sectional traverse points is varied according 
to the stack gas velocity at each point. The total sample time must be 
at least two hours.
    2.1.2 The chromium emission concentration is determined by the same 
analytical procedures described in Method 306: inductively-coupled 
plasma emission spectrometry (ICP), graphite furnace atomic absorption 
spectrometry (GFAAS), or ion chromatography with a post-column reactor 
(IC/PCR).
    2.1.2.1 Total chromium samples with high chromium concentrations 
([ge]35 [mu]g/L) may be analyzed using inductively coupled plasma 
emission spectrometry (ICP) at 267.72 nm.
    Note: The ICP analysis is applicable for this method only when the 
solution analyzed has a Cr concentration greater than or equal to 35 
[mu]g/L or five times the method detection limit as determined according 
to Appendix B in 40 CFR Part 136.
    2.1.2.2 Alternatively, when lower total chromium concentrations (<35 
[mu]g/L) are encountered, a portion of the alkaline sample solution may 
be digested with nitric acid and analyzed by graphite furnace atomic 
absorption spectroscopy (GFAAS) at 357.9 nm.
    2.1.2.3 If it is desirable to determine hexavalent chromium (Cr\+6\) 
emissions, the samples may be analyzed using an ion chromatograph 
equipped with a post-column reactor (IC/PCR) and a visible wavelength 
detector. To increase sensitivity for trace levels of Cr\+6\, a 
preconcentration system may be used in conjunction with the IC/PCR.

                       6.0 Equipment and Supplies

    Note: Mention of trade names or specific products does not 
constitute endorsement by the Environmental Protection Agency.
    6.1 Sampling Train. A schematic of the sampling train is shown in 
Figure 306A-1. The individual components of the train are available 
commercially, however, some fabrication and assembly are required.
    6.1.1 Probe Nozzle/Tubing and Sheath.
    6.1.1.1 Use approximately 6.4-mm (\1/4\-in.) inside diameter (ID) 
glass or rigid plastic tubing approximately 20 cm (8 in.) in length with 
a short 90 degree bend at one end to form the sampling nozzle. Grind a 
slight taper on the nozzle end before making the bend. Attach the nozzle 
to flexible tubing of sufficient length to enable collection of a sample 
from the stack.
    6.1.1.2 Use a straight piece of larger diameter rigid tubing (such 
as metal conduit or plastic water pipe) to form a sheath that begins 
about 2.5 cm (1 in.) from the 90 [deg] bend on the nozzle and encases 
and supports the flexible tubing.

polypropylene, or polyvinyl chloride) [sim] 6.4-mm (\1/4\-in.) to 9.5-mm 
(\3/8\-in.) ID to connect the train components.
    6.1.4.2 A combination of rigid plastic tubing and thin wall flexible 
tubing may be used as long as tubing walls do not collapse when leak-
checking the train. Metal tubing cannot be used.
    6.1.5 Impingers. Three, one-quart capacity, glass canning jars with 
vacuum seal lids, or three Greenburg-Smith (GS) design impingers 
connected in series, or equivalent, may be used.
    6.1.5.1 One-quart glass canning jar. Three separate jar containers 
are required: (1) the first jar contains the absorbing solution; (2) the 
second is empty and is used to collect any reagent carried over from the 
first container; and (3) the third contains the desiccant drying agent.
    6.1.5.2 Canning Jar Connectors. The jar containers are connected by 
leak-tight inlet and outlet tubes installed in the lids of each 
container for assembly with the train. The tubes may be made of [sim] 
6.4 mm (\1/4\-in.) ID glass or rigid plastic tubing. For the inlet tube 
of the first impinger, heat the glass or plastic tubing and draw until 
the tubing separates. Fabricate the necked tip to form an orifice tip 
that is approximately 2.4 mm (\3/32\-in.) ID.
    6.1.5.2.1 When assembling the first container, place the orifice tip 
end of the tube approximately 4.8 mm (\3/16\-in.) above the inside 
bottom of the jar.
    6.1.5.2.2 For the second container, the inlet tube need not be drawn 
and sized, but the tip should be approximately 25 mm (1 in.) above the 
bottom of the jar.
    6.1.5.2.3 The inlet tube of the third container should extend to 
approximately 12.7 mm (\1/2\-in.) above the bottom of the jar.
    6.1.5.2.4 Extend the outlet tube for each container approximately 50 
mm (2 in.) above the jar lid and downward through the lid, approximately 
12.7 mm (\1/2\-in.) beneath the bottom of the lid.
    6.1.5.3 Greenburg-Smith Impingers. Three separate impingers of the 
Greenburg-Smith (GS) design as described in Section 6.0 of Method 5 are 
required. The first GS impinger shall have a standard tip (orifice/
plate), and the second and third GS impingers shall be modified by 
replacing the orifice/plate tube with a 13 mm (\1/2\-in.) ID glass tube, 
having an unrestricted opening located 13 mm (\1/2\-in.) from the bottom 
of the outer flask.
    6.1.5.4 Greenburg-Smith Connectors. The GS impingers shall be 
connected by leak-free ground glass ``U'' tube connectors or by leak-
free non-contaminating flexible tubing. The first impinger shall contain 
the absorbing solution, the second is empty and the third contains the 
desiccant drying agent.
    6.1.6 Manometer. Inclined/vertical type, or equivalent device, as 
described in Section 6.2 of Method 2 (40 CFR Part 60, Appendix A).
    6.1.7 Critical Orifice. The critical orifice is a small restriction 
in the sample line that is located upstream of the vacuum pump. The 
orifice produces a constant sampling flow rate that is approximately 
0.021 cubic meters per minute (m3/min) or 0.75 cubic feet per 
minute (cfm).
    6.1.7.1 The critical orifice can be constructed by sealing a 2.4-mm 
(\3/32\-in.) ID brass tube approximately 14.3 mm (\9/16\-in.) in length 
inside a second brass tube that is approximately 8 mm (\5/16\-in.) ID 
and 14.3-mm (\9/16\-in.) in length .
    6.1.7.2 Materials other than brass can be used to construct the 
critical orifice as long as the flow through the sampling train can be 
maintained at approximately 0.021 cubic meter per minute (0.75) cfm.
    6.1.8 Connecting Hardware. Standard pipe and fittings, 9.5-mm (\3/
8\-in.), 6.4-mm (\1/4\-in.)

[[Page 1001]]

or 3.2-mm (\1/8\-in.) ID, may be used to assemble the vacuum pump, dry 
gas meter and other sampling train components.

Hg (30 in. Hg) vacuum in 25.4 mm HG (1 
in. Hg) increments. Locate vacuum gauge between the critical 
orifice and the vacuum pump.
    6.1.10 Pump Oiler. A glass oil reservoir with a wick mounted at the 
vacuum pump inlet that lubricates the pump vanes. The oiler should be an 
in-line type and not vented to the atmosphere. See EMTIC Guideline 
Document No. GD-041.WPD for additional information.
    6.1.11 Vacuum Pump. Gast Model 0522-V103-G18DX, or equivalent, 
capable of delivering at least 1.5 cfm at 15 in. Hg vacuum.
    6.1.12 Oil Trap/Muffler. An empty glass oil reservoir without wick 
mounted at the pump outlet to control the pump noise and prevent oil 
from reaching the dry gas meter.
    6.1.13 By-pass Fine Adjust Valve (Optional). Needle valve assembly 
6.4-mm (\1/4\-in.), Whitey 1 RF 4-A, or equivalent, that allows for 
adjustment of the train vacuum.
    6.1.13.1 A fine-adjustment valve is positioned in the optional pump 
by-pass system that allows the gas flow to recirculate through the pump. 
This by-pass system allows the tester to control/reduce the maximum 
leak-check vacuum pressure produced by the pump.
    6.1.13.1.1 The tester must conduct the post test leak check at a 
vacuum equal to or greater than the maximum vacuum encountered during 
the sampling run.
    6.1.13.1.2 The pump by-pass assembly is not required, but is 
recommended if the tester intends to leak-check the 306A train at the 
vacuum experienced during a run.
    6.1.14 Dry Gas Meter. An Equimeter Model 110 test meter or, 
equivalent with temperature sensor(s) installed (inlet/outlet) to 
monitor the meter temperature. If only one temperature sensor is 
installed, locate the sensor at the outlet side of the meter. The dry 
gas meter must be capable of measuring the gaseous volume to within 
[plusmn]2% of the true volume.
    Note: The Method 306 sampling train is also commercially available 
and may be used to perform the Method 306A tests. The sampling train may 
be assembled as specified in Method 306A with the sampling rate being 
operated at the delta H@ specified for the calibrated orifice 
located in the meter box. The Method 306 train is then operated as 
described in Method 306A.
    6.2 Barometer. Mercury aneroid barometer, or other barometer 
equivalent, capable of measuring atmospheric pressure to within 
[plusmn]2.5 mm Hg (0.1 in. Hg).
    6.2.1 A preliminary check of the barometer shall be made against a 
mercury-in-glass reference barometer or its equivalent.
    6.2.2 Tester may elect to obtain the absolute barometric pressure 
from a nearby National Weather Service station.
    6.2.2.1 The station value (which is the absolute barometric 
pressure) must be adjusted for elevation differences between the weather 
station and the sampling location. Either subtract 2.5 mm Hg 
(0.1 in. Hg) from the station value per 30 m (100 ft) of 
elevation increase or add the same for an elevation decrease.
    6.2.2.2 If the field barometer cannot be adjusted to agree within 
0.1 in. Hg of the reference barometric, repair or discard the 
unit. The barometer pressure measurement shall be recorded on the 
sampling data sheet.
    6.3 Sample Recovery. Same as Method 5, Section 6.2 (40 CFR Part 60, 
Appendix A), with the following exceptions:
    6.3.1 Probe-Liner and Probe-Nozzle Brushes. Brushes are not 
necessary for sample recovery. If a probe brush is used, it must be non-
metallic.
    6.3.2 Wash Bottles. Polyethylene wash bottle, for sample recovery 
absorbing solution.
    6.3.3 Sample Recovery Solution. Use 0.1 N NaOH or 0.1 N 
NaHCO3, whichever is used as the impinger absorbing solution, 
to replace the acetone.
    6.3.4 Sample Storage Containers.
    6.3.4.1 Glass Canning Jar. The first canning jar container of the 
sampling train may serve as the sample shipping container. A new lid and 
sealing plastic wrap shall be substituted for the container lid 
assembly.
    6.3.4.2 Polyethylene or Glass Containers. Transfer the Greenburg-
Smith impinger contents to precleaned polyethylene or glass containers. 
The samples shall be stored and shipped in 250-mL, 500-mL or 1000-mL 
polyethylene or glass containers with leak-free, non metal screw caps.
    6.3.5 pH Indicator Strip, for Cr +6 Samples. pH indicator 
strips, or equivalent, capable of determining the pH of solutions 
between the range of 7 and 12, at 0.5 pH increments.

    Note: Unless otherwise indicated, all reagents shall conform to the 
specifications established by the Committee on Analytical Reagents of 
the American Chemical Society (ACS reagent grade). Where such 
specifications are not available, use the best available grade. It is 
recommended, but not required, that reagents be checked by the 
appropriate analysis prior to field use to assure that contamination is 
below the analytical detection limit for the ICP or GFAAS total chromium 
analysis; and that contamination is below the analytical detection limit 
for

[[Page 1002]]

Cr+6 using IC/PCR for direct injection or, if selected, 
preconcentration.
    7.1 Sampling.
    7.1.1 Water. Reagent water that conforms to ASTM Specification D1193 
Type II (incorporated by reference see Sec. 63.14). All references to 
water in the method refer to reagent water unless otherwise specified. 
It is recommended that water blanks be checked prior to preparing the 
sampling reagents to ensure that the Cr content is less than three (3) 
times the anticipated detection limit of the analytical method.
    7.1.2 Sodium Hydroxide (NaOH) Absorbing Solution, 0.1 N. Dissolve 
4.0 g of sodium hydroxide in 1 liter of water to obtain a pH of 
approximately 8.5.
    7.1.3 Sodium Bicarbonate (NaHCO3) Absorbing Solution, 0.1 
N. Dissolve approximately 8.5 g of sodium bicarbonate in 1 liter of 
water to obtain a pH of approximately 8.3.
    7.1.4 Chromium Contamination.
    7.1.4.1 The absorbing solution shall not exceed the QC criteria 
noted in Method 306, Section 7.1.1 ([le]3 times the instrument detection 
limit).
    7.1.4.2 When the Cr+6 content in the field samples 
exceeds the blank concentration by at least a factor of ten (10), 
Cr+\6\ blank levels [le]10 times the detection limit will be 
allowed.

    Note: At sources with high concentrations of acids and/or 
SO2, the concentration of NaOH or NaHCO3 should be 
[ge]0.5 N to insure that the pH of the solution remains at or above 8.5 
for NaOH and 8.0 for NaHCO3 during and after sampling.

    7.1.3 Desiccant. Silica Gel, 6-16 mesh, indicating type. 
Alternatively, other types of desiccants may be used, subject to the 
approval of the Administrator.

    7.5 Quality Assurance Audit Samples.
    7.5.1 It is recommended, but not required, that a performance audit 
sample be analyzed in conjunction with the field samples. The audit 
sample should be in a suitable sample matrix at a concentration similar 
to the actual field samples.
    7.5.2 When making compliance determinations, and upon availability, 
audit samples may be obtained from the appropriate EPA regional Office 
or from the responsible enforcement authority and analyzed in 
conjunction with the field samples.

    Note: The responsible enforcement authority should be notified at 
least 30 days prior to the test date to allow sufficient time for the 
audit sample to be delivered.

 8.0 Sample Collection, Recovery, Preservation, Holding Times, Storage, 
                              and Transport

    Note: Prior to sample collection, consideration should be given as 
to the type of analysis (Cr+6 or total Cr) that will be 
performed. Deciding which analysis will be performed will enable the 
tester to determine which appropriate sample recovery and storage 
procedures will be required to process the sample.

    8.1 Sample Collection.
    8.1.1 Pretest Preparation.
    8.1.1.1 Selection of Measurement Site. Locate the sampling ports as 
specified in Section 11.0 of Method 1 (40 CFR Part 60, Appendix A).
    8.1.1.2 Location of Traverse Points.
    8.1.1.2.1 Locate the traverse points as specified in Section 11.0 of 
Method 1 (40 CFR Part 60, Appendix A). Use a total of 24 sampling points 
for round ducts and 24 or 25 points for rectangular ducts. Mark the 
pitot and sampling probe to identify the sample traversing points.
    8.1.1.2.2 For round ducts less than 12 inches in diameter, use a 
total of 16 points.
    8.1.1.3 Velocity Pressure Traverse. Perform an initial velocity 
traverse before obtaining samples. The Figure 306A-2 data sheet may be 
used to record velocity traverse data.
    8.1.1.3.1 To demonstrate that the flow rate is constant over several 
days of testing, perform complete traverses at the beginning and end of 
each day's test effort, and calculate the deviation of the flow rate for 
each daily period. The beginning and end flow rates are considered 
constant if the deviation does not exceed 10 percent. If the flow rate 
exceeds the 10 percent criteria, either correct the inconsistent flow 
rate problem, or obtain the Administrator's approval for the test 
results.
    8.1.1.3.2 Perform traverses as specified in Section 8.0 of Method 2, 
but record only the [Delta]p (velocity pressure) values for each 
sampling point. If a mass emission rate is desired, stack velocity 
pressures shall be recorded before and after each test, and an average 
stack velocity pressure determined for the testing period.
    8.1.1.4 Verification of Absence of Cyclonic Flow. Check for cyclonic 
flow during the initial traverse to verify that it does not exist. 
Perform the cyclonic flow check as specified in Section 11.4 of Method 1 
(40 CFR Part 60, Appendix A).
    8.1.1.4.1 If cyclonic flow is present, verify that the absolute 
average angle of the tangential flow does not exceed 20 degrees. If the 
average value exceeds 20 degrees at the sampling location, the flow 
condition in the stack is unacceptable for testing.

[[Page 1003]]

    8.1.1.4.2 Alternative procedures, subject to approval of the 
Administrator, e.g., installing straightening vanes to eliminate the 
cyclonic flow, must be implemented prior to conducting the testing.
    8.1.1.5 Stack Gas Moisture Measurements. Not required. Measuring the 
moisture content is optional when a mass emission rate is to be 
calculated.
    8.1.1.5.1 The tester may elect to either measure the actual stack 
gas moisture during the sampling run or utilize a nominal moisture value 
of 2 percent.
    8.1.1.5.2 For additional information on determining sampling train 
moisture, please refer to Method 4 (40 CFR Part 60, Appendix A).
    8.1.1.6 Stack Temperature Measurements. If a mass emission rate is 
to be calculated, a temperature sensor must be placed either near the 
center of the stack, or attached to the pitot tube as described in 
Section 8.3 of Method 2. Stack temperature measurements, shall be 
recorded before and after each test, and an average stack temperature 
determined for the testing period.
    8.1.1.7 Point Sampling Times. Since the sampling rate of the train 
(0.75 cfm) is maintained constant by the critical orifice, it is 
necessary to calculate specific sampling times for each traverse point 
in order to obtain a proportional sample.
    8.1.1.7.1 If the sampling period (3 runs) is to be completed in a 
single day, the point sampling times shall be calculated only once.
    8.1.1.7.2 If the sampling period is to occur over several days, the 
sampling times must be calculated daily using the initial velocity 
pressure data recorded for that day. Determine the average of the 
[Delta]p values obtained during the velocity traverse (Figure 306A-2).
    8.1.1.7.3 If the stack diameter is less than 12 inches, use 7.5 
minutes in place of 5 minutes in the equation and 16 sampling points 
instead of 24 or 25 points. Calculate the sampling times for each 
traverse point using the following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.579

Where:
n = Sampling point number.
[Delta]p = Average pressure differential across pitot tube, mm 
          H2O (in. H2O).
[Delta]Pavg = Average of [Delta]p values, mm H2O 
          (in. H2O).

    Note: Convert the decimal fractions for minutes to seconds.
    8.1.1.8 Pretest Preparation. It is recommended, but not required, 
that all items which will be in contact with the sample be cleaned prior 
to performing the testing to avoid possible sample contamination 
(positive chromium bias). These items include, but are not limited to: 
Sampling probe, connecting tubing, impingers, and jar containers.
    8.1.1.8.1 Sample train components should be: (1) Rinsed with hot tap 
water; (2) washed with hot soapy water; (3) rinsed with tap water; (4) 
rinsed with reagent water; (5) soaked in a 10 percent (v/v) nitric acid 
solution for at least four hours; and (6) rinsed throughly with reagent 
water before use.
    8.1.1.8.2 At a minimum, the tester should, rinse the probe, 
connecting tubing, and first and second impingers twice with either 0.1 
N sodium hydroxide (NaOH) or 0.1 N sodium bicarbonate 
(NaHCO3) and discard the rinse solution.
    8.1.1.8.3 If separate sample shipping containers are to be used, 
these also should be precleaned using the specified cleaning procedures.
    8.1.1.9 Preparation of Sampling Train. Assemble the sampling train 
as shown in Figure 306A-1. Secure the nozzle-liner assembly to the outer 
sheath to prevent movement when sampling.
    8.1.1.9.1 Place 250 mL of 0.1 N NaOH or 0.1 N NaHCO3 
absorbing solution into the first jar container or impinger. The second 
jar/impinger is to remain empty. Place 6 to 16 mesh indicating silica 
gel, or equivalent desiccant into the third jar/impinger until the 
container is half full ([sim] 300 to 400 g).
    8.1.1.9.2 Place a small cotton ball in the outlet exit tube of the 
third jar to collect small silica gel particles that may dislodge and 
impair the pump and/or gas meter.
    8.1.1.10 Pretest Leak-Check. A pretest leak-check is recommended, 
but not required. If the tester opts to conduct the pretest leak-check, 
the following procedures shall be performed: (1) Place the jar/impinger 
containers into an ice bath and wait 10 minutes for the ice to cool the 
containers before performing the leak check and/or start sampling; (2) 
to perform the leak check, seal the nozzle using a piece of clear 
plastic wrap placed over the end of a finger and switch on the pump; and 
(3) the train system leak rate should not exceed 0.02 cfm at a vacuum of 
380 mm Hg (15 in. Hg) or greater. If the leak rate

[[Page 1004]]

does exceed the 0.02 cfm requirement, identify and repair the leak area 
and perform the leak check again.

    Note: Use caution when releasing the vacuum following the leak 
check. Always allow air to slowly flow through the nozzle end of the 
train system while the pump is still operating. Switching off the pump 
with vacuum on the system may result in the silica gel being pulled into 
the second jar container.
    8.1.1.11 Leak-Checks During Sample Run. If, during the sampling run, 
a component (e.g., jar container) exchange becomes necessary, a leak-
check shall be conducted immediately before the component exchange is 
made. The leak-check shall be performed according to the procedure 
outlined in Section 8.1.1.10 of this method. If the leakage rate is 
found to be [le] 0.02 cfm at the maximum operating vacuum, the results 
are acceptable. If, however, a higher leak rate is obtained, either 
record the leakage rate and correct the sample volume as shown in 
Section 12.3 of Method 5 or void the sample and initiate a replacement 
run. Following the component change, leak-checks are optional, but are 
recommended as are the pretest leak-checks.
    8.1.1.12 Post Test Leak Check. Remove the probe assembly and 
flexible tubing from the first jar/impinger container. Seal the inlet 
tube of the first container using clear plastic wrap and switch on the 
pump. The vacuum in the line between the pump and the critical orifice 
must be [ge]15 in. Hg. Record the vacuum gauge measurement along with 
the leak rate observed on the train system.
    8.1.1.12.1 If the leak rate does not exceed 0.02 cfm, the results 
are acceptable and no sample volume correction is necessary.
    8.1.1.12.2 If, however, a higher leak rate is obtained 
(0.02 cfm), the tester shall either record the leakage rate 
and correct the sample volume as shown in Section 12.3 of Method 5, or 
void the sampling run and initiate a replacement run. After completing 
the leak-check, slowly release the vacuum at the first container while 
the pump is still operating. Afterwards, switch-off the pump.
    8.1.2 Sample Train Operation.
    8.1.2.1 Data Recording. Record all pertinent process and sampling 
data on the data sheet (see Figure 306A-3). Ensure that the process 
operation is suitable for sample collection.
    8.1.2.2 Starting the Test. Place the probe/nozzle into the duct at 
the first sampling point and switch on the pump. Start the sampling 
using the time interval calculated for the first point. When the first 
point sampling time has been completed, move to the second point and 
continue to sample for the time interval calculated for that point; 
sample each point on the traverse in this manner. Maintain ice around 
the sample containers during the run.
    8.1.2.3 Critical Flow. The sample line between the critical orifice 
and the pump must operate at a vacuum of [ge] 380 mm Hg ([ge]15 in. Hg) 
in order for critical flow to be maintained. This vacuum must be 
monitored and documented using the vacuum gauge located between the 
critical orifice and the pump.

    Note: Theoretically, critical flow for air occurs when the ratio of 
the orifice outlet absolute pressure to the orifice inlet absolute 
pressure is less than a factor of 0.53. This means that the system 
vacuum should be at least [ge] 356 mm Hg ([ge] 14 in. Hg) at sea level 
and [sim] 305 mm Hg ([sim] 12 in. Hg) at higher elevations.

    8.1.2.4 Completion of Test.
    8.1.2.4.1 Circular Stacks. Complete the first port traverse and 
switch off the pump. Testers may opt to perform a leak-check between the 
port changes to verify the leak rate however, this is not mandatory. 
Move the sampling train to the next sampling port and repeat the 
sequence. Be sure to record the final dry gas meter reading after 
completing the test run. After performing the post test leak check, 
disconnect the jar/impinger containers from the pump and meter assembly 
and transport the probe, connecting tubing, and containers to the sample 
recovery area.
    8.1.2.4.2 Rectangle Stacks. Complete each port traverse as per the 
instructions provided in 8.1.2.4.1.

    Note: If an approximate mass emission rate is to be calculated, 
measure and record the stack velocity pressure and temperature before 
and after the test run.

    8.2 Sample Recovery. After the train has been transferred to the 
sample recovery area, disconnect the tubing that connects the jar/
impingers. The tester shall select either the total Cr or 
Cr+\6\ sample recovery option. Samples to be analyzed for 
both total Cr and Cr+\6\ shall be recovered using the 
Cr+\6\ sample option (Section 8.2.2).

    Note: Collect a reagent blank sample for each of the total Cr or the 
Cr+\6\ analytical options. If both analyses (Cr and 
Cr+\6\) are to be conducted on the samples, collect separate 
reagent blanks for each analysis.

    8.2.1 Total Cr Sample Option.
    8.2.1.1 Shipping Container No. 1. The first jar container may either 
be used to store and transport the sample, or if GS impingers are used, 
samples may be stored and shipped in precleaned 250-mL, 500-mL or 1000-
mL polyethylene or glass bottles with leak-free, non-metal screw caps.
    8.2.1.1.1 Unscrew the lid from the first jar/impinger container.
    8.2.1.1.2 Lift the inner tube assembly almost out of the container, 
and using the wash bottle containing fresh absorbing solution, rinse the 
outside of the tube that was immersed in the container solution; rinse

[[Page 1005]]

the inside of the tube as well, by rinsing twice from the top of the 
tube down through the inner tube into the container.
    8.2.1.2 Recover the contents of the second jar/impinger container by 
removing the lid and pouring any contents into the first shipping 
container.
    8.2.1.2.1 Rinse twice, using fresh absorbing solution, the inner 
walls of the second container including the inside and outside of the 
inner tube.
    8.2.1.2.2 Rinse the connecting tubing between the first and second 
sample containers with absorbing solution and place the rinses into the 
first container.
    8.2.1.3 Position the nozzle, probe and connecting plastic tubing in 
a vertical position so that the tubing forms a ``U''.
    8.2.1.3.1 Using the wash bottle, partially fill the tubing with 
fresh absorbing solution. Raise and lower the end of the plastic tubing 
several times to allow the solution to contact the internal surfaces. Do 
not allow the solution to overflow or part of the sample will be lost. 
Place the nozzle end of the probe over the mouth of the first container 
and elevate the plastic tubing so that the solution flows into the 
sample container.
    8.2.1.3.2 Repeat the probe/tubing sample recovery procedure but 
allow the solution to flow out the opposite end of the plastic tubing 
into the sample container. Repeat the entire sample recovery procedure 
once again.
    8.2.1.4 Use approximately 200 to 300 mL of the 0.1 N NaOH or 0.1 N 
NaHCO3 absorbing solution during the rinsing of the probe 
nozzle, probe liner, sample containers, and connecting tubing.
    8.2.1.5 Place a piece of clear plastic wrap over the mouth of the 
sample jar to seal the shipping container. Use a standard lid and band 
assembly to seal and secure the sample in the jar.
    8.2.1.5.1 Label the jar clearly to identify its contents, sample 
number and date.
    8.2.1.5.2 Mark the height of the liquid level on the container to 
identify any losses during shipping and handling.
    8.2.1.5.3 Prepare a chain-of-custody sheet to accompany the sample 
to the laboratory.
    8.2.2 Cr+\6\ Sample Option.
    8.2.2.1 Shipping Container No. 1. The first jar container may either 
be used to store and transport the sample, or if GS impingers are used, 
samples may be stored and shipped in precleaned 250-mL, 500-mL or 1000-
mL polyethylene or glass bottles with leak-free non-metal screw caps.
    8.2.2.1.1 Unscrew and remove the lid from the first jar container.
    8.2.2.1.2 Measure and record the pH of the solution in the first 
container by using a pH indicator strip. The pH of the solution must be 
[ge]8.5 for NaOH and [ge]8.0 for NaHCO3. If not, discard the 
collected sample, increase the concentration of the NaOH or NaHCO3 
absorbing solution to 0.5 M and collect another air emission sample.
    8.2.2.2 After measuring the pH of the first container, follow sample 
recovery procedures described in Sections 8.2.1.1 through 8.2.1.5.

    Note: Since particulate matter is not usually present at chromium 
electroplating and/or chromium anodizing facilities, it is not necessary 
to filter the Cr+\6\ samples unless there is observed 
sediment in the collected solutions. If it is necessary to filter the 
Cr+\6\ solutions, please refer to the EPA Method 0061, 
Determination of Hexavalent Chromium Emissions from Stationary Sources, 
Section 7.4, Sample Preparation in SW-846 (see Reference 5) for 
procedure.

    8.2.3 Silica Gel Container. Observe the color of the indicating 
silica gel to determine if it has been completely spent and make a 
notation of its condition/color on the field data sheet. Do not use 
water or other liquids to remove and transfer the silica gel.
    8.2.4 Total Cr and/or Cr+\6\ Reagent Blank.
    8.2.4.1 Shipping Container No. 2. Place approximately 500 mL of the 
0.1 N NaOH or 0.1 N NaHCO3 absorbing solution in a 
precleaned, labeled sample container and include with the field samples 
for analysis.
    8.3 Sample Preservation, Storage, and Transport.
    8.3.1 Total Cr Option. Samples that are to be analyzed for total Cr 
need not be refrigerated.
    8.3.2 Cr+\6\ Option. Samples that are to be analyzed for 
Cr+\6\ must be shipped and stored at 4 [deg]C ([sim]40 
[deg]F).

    Note: Allow Cr+\6\ samples to return to ambient 
temperature prior to analysis.

    8.4 Sample Holding Times.
    8.4.1 Total Cr Option. Samples that are to be analyzed for total 
chromium must be analyzed within 60 days of collection.
    8.4.2 Cr+\6\ Option. Samples that are to be analyzed for 
Cr+\6\ must be analyzed within 14 days of collection.

                           9.0 Quality Control

    9.1 Same as Method 306, Section 9.0.

                  10.0 Calibration and Standardization

    Note: Tester shall maintain a performance log of all calibration 
results.

    10.1 Pitot Tube. The Type S pitot tube assembly shall be calibrated 
according to the procedures outlined in Section 10.1 of Method 2.
    10.2 Temperature Sensor. Use the procedure in Section 10.3 of Method 
2 to calibrate the in-stack temperature sensor.
    10.3 Metering System.
    10.3.1 Sample Train Dry Gas Meter Calibration. Calibrations may be 
performed as described in Section 16.2 of Method 5 by either the 
manufacturer, a firm who provides calibration services, or the tester.

[[Page 1006]]

    10.3.2 Dry Gas Meter Calibration Coefficient (Ym). The 
meter calibration coefficient (Ym) must be determined prior 
to the initial use of the meter, and following each field test program. 
If the dry gas meter is new, the manufacturer will have specified the 
Ym value for the meter. This Ym value can be used 
as the pretest value for the first test. For subsequent tests, the 
tester must use the Ym value established during the pretest 
calibration.
    10.3.3 Calibration Orifice. The manufacturer may have included a 
calibration orifice and a summary spreadsheet with the meter that may be 
used for calibration purposes. The spreadsheet will provide data 
necessary to determine the calibration for the orifice and meter 
(standard cubic feet volume, sample time, etc.). These data were 
produced when the initial Ym value was determined for the 
meter.
    10.3.4 Ym Meter Value Verification or Meter Calibration.
    10.3.4.1 The Ym meter value may be determined by 
replacing the sampling train critical orifice with the calibration 
orifice. Replace the critical orifice assembly by installing the 
calibration orifice in the same location. The inlet side of the 
calibration orifice is to be left open to the atmosphere and is not to 
be reconnected to the sample train during the calibration procedure.
    10.3.4.2 If the vacuum pump is cold, switch on the pump and allow it 
to operate (become warm) for several minutes prior to starting the 
calibration. After stopping the pump, record the initial dry gas meter 
volume and meter temperature.
    10.3.4.3 Perform the calibration for the number of minutes specified 
by the manufacturer's data sheet (usually 5 minutes). Stop the pump and 
record the final dry gas meter volume and temperature. Subtract the 
start volume from the stop volume to obtain the Vm and 
average the meter temperatures (tm).
    10.3.5 Ym Value Calculation. Ym is the 
calculated value for the dry gas meter. Calculate Ym using 
the following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.580

Where:

Pbar = Barometric pressure at meter, mm Hg, (in. Hg).
Pstd = Standard absolute pressure,
Metric = 760 mm Hg.
English = 29.92 in. Hg.
tm = Average dry gas meter temperature, [deg]C, ( [deg]F).
Tm = Absolute average dry gas meter temperature,
Metric [deg]K = 273 + tm ( [deg]C).
English [deg]R = 460 + tm( [deg]F).
Tstd = Standard absolute temperature,
Metric = 293 [deg]K.
English = 528 [deg]R.
Vm = Volume of gas sample as measured (actual) by dry gas 
          meter, dcm,(dcf).
Vm(std),mfg = Volume of gas sample measured by manufacture's 
          calibrated orifice and dry gas meter, corrected to standard 
          conditions (pressure/temperature) dscm (dscf).
Ym = Dry gas meter calibration factor, (dimensionless).

    10.3.6 Ym Comparison. Compare the Ym value 
provided by the manufacturer (Section 10.3.3) or the pretest 
Ym value to the post test Ym value using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TR17OC00.581

    10.3.6.1 If this ratio is between 0.95 and 1.05, the designated 
Ym value for the meter is acceptable for use in later 
calculations.
    10.3.6.1.1 If the value is outside the specified range, the test 
series shall either be: 1)

[[Page 1007]]

voided and the samples discarded; or 2) calculations for the test series 
shall be conducted using whichever meter coefficient value (i.e., 
manufacturers's/pretest Ym value or post test Ym 
value) produces the lowest sample volume.
    10.3.6.1.2 If the post test dry gas meter Ym value 
differs by more than 5% as compared to the pretest value, either perform 
the calibration again to determine acceptability or return the meter to 
the manufacturer for recalibration.
    10.3.6.1.3 The calibration may also be conducted as specified in 
Section 10.3 or Section 16.0 of Method 5 (40 CFR Part 60, Appendix A), 
except that it is only necessary to check the calibration at one flow 
rate of [sim] 0.75 cfm.
    10.3.6.1.4 The calibration of the dry gas meter must be verified 
after each field test program using the same procedures.
    Note: The tester may elect to use the Ym post test value 
for the next pretest Ym value; e.g., Test 1 post test 
Ym value and Test 2 pretest Ym value would be the 
same.

    10.4 Barometer. Calibrate against a mercury barometer that has been 
corrected for temperature and elevation.
    10.5 ICP Spectrometer Calibration. Same as Method 306, Section 10.2.
    10.6 GFAA Spectrometer Calibration. Same as Method 306, Section 
10.3.
    10.7 IC/PCR Calibration. Same as Method 306, Section 10.4.

                       11.0 Analytical Procedures

    Note: The method determines the chromium concentration in [mu]g Cr/

                         13.0 Method Performance

    13.1 Range. The recommended working range for all of the three 
analytical techniques starts at five times the analytical detection 
limit (see also Method 306, Section 13.2.2). The upper limit of all 
three techniques can be extended indefinitely by appropriate dilution.
    13.2 Sensitivity.
    13.2.1 Analytical Sensitivity. The estimated instrumental detection 
limits listed are provided as a guide for an instrumental limit. The 
actual method detection limits are sample and instrument dependent and 
may vary as the sample matrix varies.
    13.2.1.1 ICP Analytical Sensitivity. The minimum estimated detection 
limits for ICP, as reported in Method 6010A and the recently revised 
Method 6010B of SW-846 (Reference 1), are 7.0 [mu]g Cr/L and 4.7 [mu]g 
Cr/L, respectively.
    13.2.1.2 GFAAS Analytical Sensitivity. The minimum estimated 
detection limit for GFAAS, as reported in Methods 7000A and 7191 of SW-
846 (Reference 1), is 1.0 [mu]g Cr/L.
    13.2.1.3 IC/PCR Analytical Sensitivity. The minimum detection limit 
for IC/PCR with a preconcentrator, as reported in Methods 0061 and 7199 
of SW-846 (Reference 1), is 0.05 [mu]g Cr+6/L.
    13.2.2 In-stack Sensitivity. The in-stack sensitivity depends upon 
the analytical detection limit, the volume of stack gas sampled, and the 
total volume of the impinger absorbing solution plus the rinses. Using 
the analytical detection limits given in Sections 13.2.1.1, 13.2.1.2, 
and 13.2.1.3; a stack gas sample volume of 1.7 dscm; and a total liquid 
sample volume of 500 mL; the corresponding in-stack detection limits are 
0.0014 mg Cr/dscm to 0.0021 mg Cr/dscm for ICP, 0.00029 mg Cr/dscm for 
GFAAS, and 0.000015 mg Cr+36/dscm for IC/PCR with 
preconcentration.
    Note: It is recommended that the concentration of Cr in the 
analytical solutions be at least five times the analytical detection 
limit to optimize sensitivity in the analyses. Using this guideline and 
the same assumptions for impinger sample volume and stack gas sample 
volume (500 mL and 1.7 dscm, respectively), the recommended minimum 
stack concentrations for optimum sensitivity are 0.0068 mg Cr/dscm to 
0.0103 mg Cr/dscm for ICP, 0.0015 mg Cr/dscm for GFAAS, and 0.000074 mg 
Cr+6 dscm for IC/PCR with preconcentration. If required, the 
in-stack detection limits can be improved by either increasing the 
sampling time, the stack gas sample volume, reducing the volume of the 
digested sample for GFAAS, improving the analytical detection limits, or 
any combination of the three.

    13.3 Precision.
    13.3.1 The following precision data have been reported for the three 
analytical methods. In each case, when the sampling precision is 
combined with the reported analytical precision, the resulting overall 
precision may decrease.
    13.3.2 Bias data is also reported for GFAAS.
    13.4 ICP Precision.
    13.4.1 As reported in Method 6010B of SW-846 (Reference 1), in an 
EPA round-robin Phase 1 study, seven laboratories applied the ICP 
technique to acid/distilled water matrices that had been spiked with 
various metal concentrates. For true values of 10, 50, and 150 [mu]g Cr/
L; the mean reported values were 10, 50, and 149 [mu]g Cr/L; and the 
mean percent relative standard deviations were 18, 3.3, and 3.8 percent, 
respectively.
    13.4.2 In another multilaboratory study cited in Method 6010B, a 
mean relative standard of 8.2 percent was reported for an aqueous sample 
concentration of approximately 3750 [mu]g Cr/L.
    13.5 GFAAS Precision. As reported in Method 7191 of SW-846 
(Reference 1), in a single laboratory (EMSL), using Cincinnati, Ohio tap 
water spiked at concentrations of 19, 48, and 77 [mu]g Cr/L, the 
standard deviations were [plusmn]0.1, [plusmn]0.2, and [plusmn]0.8, 
respectively. Recoveries at these levels were 97 percent, 101 percent, 
and 102 percent, respectively.
    13.6 IC/PCR Precision. As reported in Methods 0061 and 7199 of SW-
846 (Reference 1), the precision of IC/PCR with sample preconcentration 
is 5 to 10 percent; the overall precision for sewage sludge incinerators 
emitting 120 ng/dscm of Cr+6 and 3.5 [mu]g/dscm of total Cr 
is 25 percent and 9 percent, respectively; and for hazardous waste 
incinerators emitting 300 ng/dscm of Cr+6 the precision is 20 
percent.

                        14.0 Pollution Prevention

    14.1 The only materials used in this method that could be considered 
pollutants are the chromium standards used for instrument calibration 
and acids used in the cleaning of the collection and measurement 
containers/labware, in the preparation of standards, and in the acid

 Method 306B--Surface Tension Measurement for Tanks Used at Decorative 
        Chromium Electroplating and Chromium Anodizing Facilities

    Note: This method does not include all of the specifications (e.g., 
equipment and supplies) and procedures (e.g., sampling and analytical) 
essential to its performance. Some material is incorporated by reference 
from other methods in 40 CFR Part 60, Appendix A and in this part. 
Therefore, to obtain reliable results, persons using this method should 
have a thorough knowledge of at least Methods 5 and 306.

                        1.0 Scope and Application

    1.1 Analyte. Not applicable.
    1.2 Applicability. This method is applicable to all decorative 
chromium plating and

[[Page 1015]]

chromium anodizing operations, and continuous chromium plating at iron 
and steel facilities where a wetting agent is used in the tank as the 
primary mechanism for reducing emissions from the surface of the plating 
solution.

                          2.0 Summary of Method

    2.1 During an electroplating or anodizing operation, gas bubbles 
generated during the process rise to the surface of the liquid and 
burst. Upon bursting, tiny droplets of chromic acid become entrained in 
ambient air. The addition of a wetting agent to the tank bath reduces 
the surface tension of the liquid and diminishes the formation of these 
droplets.
    2.2 This method determines the surface tension of the bath using a 
stalagmometer or a tensiometer to confirm that there is sufficient 
wetting agent present.

                        11.0 Analytical Procedure

    11.1 Procedure. The surface tension of the tank bath may be measured 
by using a tensiometer, a stalagmometer or any other equivalent surface 
tension measuring device approved by the Administrator for measuring 
surface tension in dynes per centimeter. If the tensiometer is used, the 
procedures specified in ASTM Method D 1331-89 must be followed. If a 
stalagmometer or other device is used to measure surface tension, the 
instructions provided with the measuring device must be followed.
    11.2 Frequency of Measurements.
    11.2.1 Measurements of the bath surface tension are performed using 
a progressive system which decreases the frequency of surface tension 
measurements required when the proper surface tension is maintained.
    11.2.1.1 Initially, following the compliance date, surface tension 
measurements must be conducted once every 4 hours of tank operation for 
the first 40 hours of tank operation.
    11.2.1.2 Once there are no exceedances during a period of 40 hours 
of tank operation, measurements may be conducted once every 8 hours of 
tank operation.
    11.2.1.3 Once there are no exceedances during a second period of 40 
consecutive hours of tank operation, measurements may be conducted once 
every 40 hours of tank operation on an on-going basis, until an 
exceedance occurs. The maximum time interval for measurements is once 
every 40 hours of tank operation.
    11.2.2 If a measurement of the surface tension of the solution is 
above the 45 dynes per centimeter limit, or above an alternate surface 
tension limit established during the performance test, the time interval 
shall revert back to the original monitoring schedule of once every 4 
hours. A subsequent decrease in frequency would then be allowed 
according to Section 11.2.1.

must be measured as specified in Section 11.2.
    12.1.2 The measurements must be recorded in the log book. In 
addition to the record of surface tension measurements, the frequency of 
fume suppressant maintenance additions and the amount of fume 
suppressant added during each maintenance addition must be recorded in 
the log book.
    12.1.3 The log book will be readily available for inspection by 
regulatory personnel.
    12.2 Instructions for Apparatus Used in Measuring Surface Tension.
    12.2.1 Included with the log book must be a copy of the instructions 
for the apparatus used for measuring the surface tension of the plating 
or anodizing bath.

 Method 307--Determination of Emissions From Halogenated Solvent Vapor 
            Cleaning Machines Using a Liquid Level Procedure

                     1. Applicability and Principle

    1.1 Applicability. This method is applicable to the determination of 
the halogenated solvent emissions from solvent vapor cleaners in the 
idling mode.
    1.2 Principle. The solvent level in the solvent cleaning machine is 
measured using inclined liquid level indicators. The change in liquid 
level corresponds directly to the amount of solvent lost from the 
solvent cleaning machine.

                              2. Apparatus

    Note: Mention of trade names or specific products does not 
constitute endorsement by the Environmental Protection Agency.
    2.1 Inclined Liquid Level Indicator. A schematic of the inclined 
liquid level indicators used in this method is shown in figure 307-1; 
two inclined liquid level indicators having 0.05 centimeters divisions 
or smaller shall be used. The liquid level indicators shall be made of 
glass, Teflon, or any similar material that will not react with the 
solvent being used. A 6-inch by 1-inch slope is recommended; however the 
slope may vary depending on the size and design of the solvent cleaning 
machine.
    Note: It is important that the inclined liquid level indicators be 
constructed with ease of reading in mind. The inclined liquid level 
indicators should also be mounted so that they can be raised or lowered 
if necessary to suit the solvent cleaning machine size.

    2.2 Horizontal Indicator. Device to check the inclined liquid level 
indicators orientation relative to horizontal.
    2.3 Velocity Meter. Hotwire and vane anemometers, or other devices 
capable of measuring the flow rates ranging from 0 to 15.2 meters per 
minute across the solvent cleaning machine.

                              3. Procedure

    3.1 Connection of the Inclined Liquid Level Indicator. Connect one 
of the inclined liquid level indicators to the boiling sump drain and 
the other inclined liquid level indicator to the immersion sump drain 
using Teflon tubing and the appropriate fittings. A schematic diagram is 
shown in figure 307-2.

[[Page 1017]]

[GRAPHIC] [TIFF OMITTED] TC01MY92.076

    3.2 Positioning of Velocity Meter. Position the velocity meter so 
that it measures the flow rate of the air passing directly across the 
solvent cleaning machine.
    3.3 Level the Inclined Liquid Level Indicators.
    3.4 Initial Inclined Liquid Level Indicator Readings. Open the sump 
drainage valves. Allow the solvent cleaning machine to operate long 
enough for the vapor zone to form and the system to stabilize (check 
with manufacturer). Record the inclined liquid level indicators readings 
and the starting time on the data sheet. A sample data sheet is provided 
in figure 307-3.

    A gas sample is extracted from the sampling point in the stack. The 
methanol is collected in deionized distilled water and adsorbed on 
silica gel. The sample is returned to the laboratory where the methanol 
in the water fraction is separated from other organic compounds with a 
gas chromatograph (GC) and is then measured by a flame ionization 
detector (FID). The fraction adsorbed on silica gel is extracted with an 
aqueous solution of n-propanol and is then separated and measured by GC/
FID.

    8.1 Sampling. The following items are required for sampling:
    8.1.1 Preparation of Collection Train. Measure 20 ml of water into 
the midget impinger. The adsorbent tube must contain 520 mg of silica 
gel in the front section and 260 mg of silica gel in the backup section. 
Assemble the train as shown in Figure 308-1. An optional, second 
impinger that is left empty may be placed in front of the water-
containing impinger to act as a condensate trap. Place crushed ice and 
water around the impinger.

    8.1.2 Leak Check. A leak check prior to the sampling run is 
optional; however, a leak check after the sampling run is mandatory. The 
leak-check procedure is as follows:
    Temporarily attach a suitable (e.g., 0-to 40-ml/min) rotameter to 
the outlet of the DGM, and place a vacuum gauge at or near the probe 
inlet. Plug the probe inlet, pull a vacuum of at least 250 mm (10 inch) 
Hg, and note the flow rate as indicated by the rotameter. A leakage rate 
not in excess of 2 percent of the average sampling rate is acceptable.

    Note: Carefully release the probe inlet plug before turning off the 
pump.

    8.1.3 Sample Collection. Record the initial DGM reading and 
barometric pressure. To begin sampling, position the tip of the 
Teflon[reg] tubing at the sampling point, connect the tubing 
to the impinger, and start the pump. Adjust the sample flow to a 
constant rate between 200 and 1000 ml/min as indicated by the rotameter. 
Maintain this constant rate ([plusmn]10 percent) during the entire 
sampling run. Take readings (DGM, temperatures at DGM and at impinger 
outlet, and rate meter) at least every 5 minutes. Add more ice during 
the run to keep the temperature of the gases leaving the last impinger 
at 20 [deg]C (68 [deg]F) or less. At the conclusion of each run,

[[Page 1021]]

turn off the pump, remove the Teflon[reg] tubing from the 
stack, and record the final readings. Conduct a leak check as in section 
8.1.2. (This leak check is mandatory.) If a leak is found, void the test 
run or use procedures acceptable to the Administrator to adjust the 
sample volume for the leakage.
    8.2 Sample Recovery. The following items are required for sample 
recovery:
    8.2.1 Impinger. Disconnect the impinger. Pour the contents of the 
midget impinger into a graduated cylinder. Rinse the midget impinger and 
the connecting tubes with water, and add the rinses to the graduated 
cylinder. Record the sample volume. Transfer the sample to a glass vial 
and cap with a Teflon[reg] septum. Discard any excess sample. 
Place the samples in an ice chest for shipment to the laboratory.
    8.2.2. Adsorbent Tubes. Seal the silica gel adsorbent tubes and 
place them in an ice chest for shipment to the laboratory.

------------------------------------------------------------------------

    9.2 Applicability. When the method is used to analyze samples to 
demonstrate compliance with a source emission regulation, an audit 
sample must be analyzed, subject to availability.
    9.3 Audit Procedure. Analyze an audit sample with each set of 
compliance samples. Concurrently analyze the audit sample and a set of 
compliance samples in the same manner to evaluate the technique of the 
analyst and the standards preparation. The same analyst, analytical 
reagents, and analytical system shall be used both for the compliance 
samples and the EPA audit sample.
    9.4 Audit Sample Availability. Audit samples will be supplied only 
to enforcement agencies for compliance tests. Audit samples may be 
obtained by writing: Source Test Audit Coordinator (MD-77B), Air 
Measurement Research Division, National Exposure Research Laboratory, 
U.S. Environmental Protection Agency, Research Triangle Park, NC 27711; 
or by calling the Source Test Audit Coordinator (STAC) at (919) 541-
7834. The audit sample request must be made at least 30 days prior to 
the scheduled compliance sample analysis.
    9.5 Audit Results. Calculate the audit sample concentration 
according to the calculation procedure provided in the audit 
instructions included with the audit sample. Fill in the audit sample 
concentration and the analyst's name on the audit response form included 
with the audit instructions. Send one copy to the EPA Regional Office or 
the appropriate enforcement agency and a second copy to the STAC. The 
EPA Regional office or the appropriate enforcement agency will report 
the results of the audit to the laboratory being audited. Include this 
response with the results of the compliance samples in relevant reports 
to the EPA Regional Office or the appropriate enforcement agency.

                  10.0 Calibration and Standardization

    10.1 Metering System. The following items are required for the 
metering system:
    10.1.1 Initial Calibration.
    10.1.1.1 Before its initial use in the field, first leak-check the 
metering system (drying tube, needle valve, pump, rotameter, and DGM) as 
follows: Place a vacuum gauge at the inlet to the drying tube, and pull 
a vacuum of 250 mm (10 inch) Hg; plug or pinch off the outlet of the 
flow meter, and then turn off the pump. The vacuum shall remain stable 
for at least 30 seconds. Carefully release the vacuum gauge before 
releasing the flow meter end.
    10.1.1.2 Next, remove the drying tube, and calibrate the metering 
system (at the sampling flow rate specified by the method) as follows: 
Connect an appropriately sized wet test meter (e.g., 1 liter per 
revolution (0.035 cubic feet per revolution)) to the inlet of the drying 
tube. Make three independent calibrations runs, using at least five 
revolutions of the DGM per run. Calculate the calibration factor, Y (wet 
test meter calibration volume divided by the DGM volume, both volumes 
adjusted to the same reference temperature and pressure), for each run, 
and average the results. If any Y-value deviates by more than 2 percent 
from the average, the metering system is unacceptable for use. 
Otherwise, use the average as the calibration factor for subsequent test 
runs.
    10.1.2 Posttest Calibration Check. After each field test series, 
conduct a calibration check as in section 10.1.1 above, except for the 
following variations: (a) The leak check is not to be conducted, (b) 
three, or more revolutions of the DGM may be used, and (c) only two 
independent runs need be made. If the calibration factor does not 
deviate by more than 5 percent from the initial calibration factor 
(determined in section 10.1.1), then the DGM volumes obtained during the 
test series are acceptable. If the calibration factor deviates by more 
than 5 percent, recalibrate the metering system as in section 10.1.1, 
and for the calculations, use the calibration factor (initial or 
recalibration) that yields the lower gas volume for each test run.
    10.1.3 Temperature Sensors. Calibrate against mercury-in-glass 
thermometers.

[[Page 1022]]

    10.1.4 Rotameter. The rotameter need not be calibrated, but should 
be cleaned and maintained according to the manufacturer's instruction.
    10.1.5 Barometer. Calibrate against a mercury barometer.
    10.2 Gas Chromatograph. The following procedures are required for 
the gas chromatograph:
    10.2.1 Initial Calibration. Inject 1 [mu]l of each of the standards 
prepared in sections 7.2.3.3 and 7.2.3.4 into the GC and record the 
response. Repeat the injections for each standard until two successive 
injections agree within 5 percent. Using the mean response for each 
calibration standard, prepare a linear least squares equation relating 
the response to the mass of methanol in the sample. Perform the 
calibration before analyzing each set of samples.
    10.2.2 Continuing Calibration. At the beginning of each day, analyze 
the mid level calibration standard as described in section 10.5.1. The 
response from the daily analysis must agree with the response from the 
initial calibration within 10 percent. If it does not, the initial 
calibration must be repeated.

                        11.0 Analytical Procedure

    11.1 Gas Chromatograph Operating Conditions. The following operating 
conditions are required for the GC:
    11.1.1 Injector. Configured for capillary column, splitless, 200 
[deg]C (392 [deg]F).
    11.1.2 Carrier. Helium at 10 ml/min.
    11.1.3 Oven. Initially at 45 [deg]C for 3 minutes; then raise by 10 
[deg]C to 70 [deg]C; then raise by 70 [deg]C/min to 200 [deg]C.
    11.2 Impinger Sample. Inject 1 [mu]l of the stored sample into the 
GC. Repeat the injection and average the results. If the sample response 
is above that of the highest calibration standard, either dilute the 
sample until it is in the measurement range of the calibration line or 
prepare additional calibration standards. If the sample response is 
below that of the lowest calibration standard, prepare additional 
calibration standards. If additional calibration standards are prepared, 
there shall be at least two that bracket the response of the sample. 
These standards should produce approximately 50 percent and 150 percent 
of the response of the sample.
    11.3 Silica Gel Adsorbent Sample. The following items are required 
for the silica gel adsorbent samples:
    11.3.1 Preparation of Samples. Extract the front and backup sections 
of the adsorbent tube separately. With a file, score the glass adsorbent 
tube in front of the first section of silica gel. Break the tube open. 
Remove and discard the glass wool. Transfer the first section of the 
silica gel to a 5-ml glass vial and stopper the vial. Remove the spacer 
between the first and second section of the adsorbent tube and discard 
it. Transfer the second section of silica gel to a separate 5-ml glass 
vial and stopper the vial.
    11.3.2 Desorption of Samples. Add 3 ml of the 10 percent n-propanol 
solution to each of the stoppered vials and shake or vibrate the vials 
for 30 minutes.
    11.3.3 Inject a 1-[mu]l aliquot of the diluted sample from each vial 
into the GC. Repeat the injection and average the results. If the sample 
response is above that of the highest calibration standard, either 
dilute the sample until it is in the measurement range of the 
calibration line or prepare additional calibration standards. If the 
sample response is below that of the lowest calibration standard, 
prepare additional calibration standards. If additional calibration 
standards are prepared, there shall be at least two that bracket the 
response of the sample. These standards should produce approximately 50 
percent and 150 percent of the response of the sample.

    1.1 Data Quality Objectives:
    In the production of ethylene-propylene terpolymer crumb rubber, the 
polymer is recovered from solution by flashing off the solvent with 
steam and hot water. The resulting water-crumb slurry is then pumped to 
the finishing units. Certain amounts of solvent (hexane being the most 
commonly used solvent) and diene monomer remain in the crumb. The 
analyst uses the following procedure to determine those amounts.

                          2.0 Summary of Method

    2.1 The crumb rubber sample is dissolved in toluene to which heptane 
has been added as an internal standard. Acetone is then added to this 
solution to precipitate the crumb, and the supernatant is analyzed for 
hexane and diene by a gas chromatograph equipped with a flame ionization 
detector (FID).

                             3.0 Definitions

    3.1 Included in text as needed.

                            4.0 Interferences

    4.1 None known.
    4.2 Benzene, introduced as a contaminant in the toluene solvent, 
elutes between methyl cyclopentane and cyclohexane. However, the benzene 
peak is completely resolved.
    4.3 2,2-dimethyl pentane, a minor component of the hexane used in 
our process, elutes just prior to methyl cyclopentane. It is included as 
``hexane'' in the analysis whether it is integrated separately or 
included in the methyl cyclopentane peak.

                               5.0 Safety

    5.1 This procedure does not purport to address all of the safety 
concerns associated with its use. It is the responsibility of the user 
of this procedure to establish appropriate safety and health practices 
and determine the applicability of regulatory limitations prior to use.
    5.2 Chemicals used in this analysis are flammable and hazardous (see 
specific toxicity information below). Avoid contact with sources of 
ignition during sample prep. All handling should be done beneath a hood. 
Playtex or nitrile gloves recommended.
    5.3 Hexane is toxic by ingestion and inhalation. Vapor inhalation 
causes irritation of nasal and respiratory passages, headache, 
dizziness, nausea, central nervous system depression. Chronic 
overexposure can cause severe nerve damage. May cause irritation on 
contact with skin or eyes. May cause damage to kidneys.
    5.4 Termonomer may be harmful by inhalation, ingestion, or skin 
absorption. Vapor or mist is irritating to the eyes, mucous membranes, 
and upper respiratory tract. Causes skin irritation.
    5.5 Toluene is harmful or fatal if swallowed. Vapor harmful if 
inhaled. Symptoms: headache, dizziness, hallucinations, distorted 
perceptions, changes in motor activity, nausea, diarrhea, respiratory 
irritation, central nervous system depression, unconsciousness, liver, 
kidney and lung damage. Contact can cause severe eye irritation. May 
cause skin irritation. Causes irritation of eyes, nose, and throat.

[[Page 1026]]

    5.6 Acetone, at high concentrations or prolonged overexposure, may 
cause headache, dizziness, irritation of eyes and respiratory tract, 
loss of strength, and narcosis. Eye contact causes severe irritation; 
skin contact may cause mild irritation. Concentrations of 20,000 ppm are 
immediately dangerous to life and health.
    5.7 Heptane is harmful if inhaled or swallowed. May be harmful if 
absorbed through the skin. Vapor or mist is irritating to the eyes, 
mucous membranes, and upper respiratory tract. Prolonged or repeated 
exposure to skin causes defatting and dermatitis.
    5.8 The steam oven used to dry the polymer in this procedure is set 
at 110 [deg]C. Wear leather gloves when removing bottles from the oven.

    7.5 Polymer Dissolving Solution (``PDS'')--Heptane (as internal 
standard) in toluene. This solution contains 0.3g of heptane internal 
standard per 100 ml of solution.
    7.5.1 Preparation of Polymer Dissolving Solution. Fill a 4,000-ml 
volumetric flask about \3/4\ full with toluene.
    7.5.2 Add 100 ml of the internal standard solution (section 7.4 of 
this method) to the flask using the 100ml pipette.
    7.5.3 Fill the flask to the mark with toluene. Discard any excess.
    7.5.4 Add a large magnetic stirring bar to the flask and mix by 
stirring.
    7.5.5 Transfer the polymer solvent solution to the one-gallon 
labeled container with 50ml volumetric dispenser attached.
    7.5.6 Purity Check: Analyze according to section 11.2. NOTE: You 
must ``precipitate'' the sample with an equal part of acetone (thus 
duplicating actual test conditions-- see section 11.1 of this method, 
sample prep) before analyzing. Analyze the reagent 3 times to quantify 
the C6 and termonomer interferences. Inspect the results to 
ensure good agreement among the three runs (within 10%).
    7.5.7 Tag the bottle with the following information:

     POLYMER DISSOLVING SOLUTION FOR C6 IN CRUMB ANALYSIS
     PREPARER'S NAME
     DATE
     CALS FILE ID'S OF THE THREE ANALYSES FOR PURITY (from section 7.5.6 
of this method)

    7.6 Quality Control Solution: the quality control solution is 
prepared by adding specific amounts of mixed hexanes (barge hexane), n-
nonane and termonomer to some polymer dissolving solution. Nonane elutes 
in the same approximate time region as termonomer and is used to 
quantify in that region because it has a longer shelf life. Termonomer, 
having a high tendency to polymerize, is used in the QC solution only to 
ensure that both termonomer isomers elute at the proper time.
    First, a concentrated stock solution is prepared; the final QC 
solution can then be prepared by diluting the stock solution.
    7.6.1 In preparation of stock solution, fill a 1-liter volumetric 
flask partially with polymer dissolving solution (PDS)--see section 7.5 
of this method. Add 20.0 ml barge hexane, 5.0 ml n-nonane, and 3 ml 
termonomer. Finish filling the volumetric to the mark with PDS.
    7.6.2 In preparation of quality control solution, dilute the quality 
control stock solution (above) precisely 1:10 with PDS, i.e. 10 ml of 
stock solution made up to 100 ml (volumetric flask) with PDS. Pour the 
solution into a 4 oz. Boston round bottle and store in the refrigerator.

             8.0 Sample Collection, Preservation and Storage

    8.1 Line up facility to catch crumb samples. The facility is a 
special facility where the sample is drawn.
    8.1.1 Ensure that the cock valve beneath facility is closed.
    8.1.2 Line up the system from the slurry line cock valve to the cock 
valve at the nozzle on the stripper.
    8.1.3 Allow the system to flush through facility for a period of 30 
seconds.
    8.2 Catch a slurry crumb sample.
    8.2.1 Simultaneously close the cock valves upstream and downstream 
of facility.
    8.2.2 Close the cock valve beneath the slurry line in service.
    8.2.3 Line up the cooling tower water through the sample bomb water 
jacket to the sewer for a minimum of 30 minutes.
    8.2.4 Place the sample catching basket beneath facility and open the 
cock valve underneath the bomb to retrieve the rubber crumb.
    8.2.5 If no rubber falls by gravity into the basket, line up 
nitrogen to the bleeder upstream of the sample bomb and force the rubber 
into the basket.
    8.2.6 Close the cock valve underneath the sample bomb.
    8.3 Fill a plastic ``Whirl-pak'' sample bag with slurry crumb and 
send it to the lab immediately.
    8.4 Once the sample reaches the lab, it should be prepped as soon as 
possible to avoid hexane loss through evaporation. Samples which have 
lain untouched for more than 30 minutes should be discarded.

                           9.0 Quality Control

    Quality control is monitored via a computer program that tracks 
analyses of a prepared QC sample (from section 7.6.2 of this method). 
The QC sample result is entered daily into the program, which plots the 
result as a data point on a statistical chart. If the data point does 
not satisfy the ``in-control'' criteria (as defined by the lab quality 
facilitator), an ``out-of-control'' flag appears, mandating corrective 
action.
    In addition, the area of the n-heptane peak is monitored so that any 
errors in making up the polymer dissolving solution will be caught and 
corrected. Refer to section 12.4 of this method.

    9.1 Fill an autosampler vial with the quality control solution (from 
section 7.6.2 of this method) and analyze on the GC as normal (per 
section 11 of this method).
    9.2 Add the concentrations of the 5 hexane isomers as they appear on 
the CALS printout. Also include the 2,2-dimethyl-pentane peak just ahead 
of the methyl cyclopentane (the fourth major isomer) peak in the event 
that the peak integration split this peak out. Do not include the 
benzene peak in the sum.

[[Page 1028]]

Note the nonane concentration. Record both results (total hexane and 
nonane) in the QC computer program. If out of control, and GC appears to 
be functioning within normal parameters, reanalyze a fresh control 
sample. If the fresh QC is not in control, check stock solution for 
contaminants or make up a new QC sample with the toluene currently in 
use. If instrument remains out-of-control, more thorough GC 
troubleshooting may be needed.
    Also, verify that the instrument has detected both isomers of 
termonomer (quantification not necessary--see section 7.0 of this 
method).
    9.3 Recovery efficiency must be determined for high ethylene 
concentration, low ethylene concentration, E-P terpolymer, or oil 
extended samples and whenever modifications are made to the method. 
Recovery shall be between 70 and 130 percent. All test results must be 
corrected by the recovery efficiency value (R).
    9.3.1 Approximately 10 grams of wet EPDM crumb (equivalent to about 
5 grams of dry rubber) shall be added to six sample bottles containing 
100 ml of hexane in crumb polymer dissolving solution (toluene 
containing 0.3 gram n-heptane/100 ml solution). The polymer shall be 
dissolved by agitating the bottles on a shaker for 4 hours. The polymer 
shall be precipitated using 100 ml acetone.
    9.3.2 The supernatant liquid shall be decanted from the polymer. 
Care shall be taken to remove as much of the liquid phase from the 
sample as possible to minimize the effect of retained liquid phase upon 
the next cycle of the analysis. The supernatant liquid shall be analyzed 
by gas chromatography using an internal standard quantitation method 
with heptane as the internal standard.
    9.3.3 The precipitated polymer from the steps described above shall 
be redissolved using toluene as the solvent. No heptane shall be added 
to the sample in the second dissolving step. The toluene solvent and 
acetone precipitant shall be determined to be free of interfering 
compounds.
    9.3.4 The rubber which was dissolved in the toluene shall be 
precipitated with acetone as before, and the supernatant liquid decanted 
from the precipitated polymer. The liquid shall be analyzed by gas 
chromatography and the rubber phase dried in a steam-oven to determine 
the final polymer weight.
    9.3.5 The ratios of the areas of the hexane peaks and of the heptane 
internal standard peak shall be calculated for each of the six samples 
in the two analysis cycles outlined above. The area ratios of the total 
hexane to heptane (R1) shall be determined for the two analysis cycles 
of the sample set. The ratio of the values of R1 from the second 
analysis cycle to the first cycle shall be determined to give a second 
ratio (R2).

                  10.0 Calibration and Standardization

    The procedure for preparing a Quality Control sample with the 
internal standard in it is outlined in section 7.6 of this method.

    10.1 The relative FID response factors for n-heptane, the internal 
standard, versus the various hexane isomers and termonomer are 
relatively constant and should seldom need to be altered. However 
Baseline construction is a most critical factor in the production of 
good data. For this reason, close attention should be paid to peak 
integration. Procedures for handling peak integration will depend upon 
the data system used.
    10.2 If recalibration of the analysis is needed, make up a 
calibration blend of the internal standard and the analytes as detailed 
below and analyze it using the analytical method used for the samples.
    10.2.1 Weigh 5 g heptane into a tared scintillation vial to five 
places.
    10.2.2 Add 0.2 ml termonomer to the vial and reweigh.
    10.2.3 Add 0.5 ml hexane to the vial and reweigh.
    10.2.4 Cap, and shake vigorously to mix.
    10.2.5 Calculate the weights of termonomer and of hexane added and 
divide their weights by the weight of the n-heptane added. The result is 
the known of given value for the calibration.
    10.2.6 Add 0.4 ml of this mixture to a mixture of 100 ml toluene and 
100 ml of acetone. Cap and shake vigorously to mix.
    10.2.7 Analyze the sample.
    10.2.8 Divide the termonomer area and the total areas of the hexane 
peaks by the n-heptane area. This result is the ``found'' value for the 
calibration.
    10.2.9 Divide the appropriate ``known'' value from 10.2.5 by the 
found value from 10.2.8. The result is the response factor for the 
analyte in question. Previous work has shown that the standard deviation 
of the calibration method is about 1% relative.

                             11.0 Procedure

    11.1 SAMPLE PREPARATION
    11.1.1 Tare an 8oz sample bottle--Tag attached, cap off; record 
weight and sample ID on tag in pencil.
    11.1.2 Place crumb sample in bottle: RLA-3: 10 g (gives a dry wt. of 
[sim]5.5 g).
    11.1.3 Dispense 100ml of PDS into each bottle. SAMPLE SHOULD BE 
PLACED INTO SOLUTION ASAP TO AVOID HEXANE LOSS--Using ``Dispensette'' 
pipettor. Before dispensing, ``purge'' the dispensette (25% of its 
volume) into a waste bottle to eliminate any voids.
    11.1.4 Tightly cap bottles and load samples into shaker.
    11.1.5 Insure that ``ON-OFF'' switch on the shaker itself is ``ON.''
    11.1.6 Locate shaker timer. Insure that toggle switch atop timer 
control box is in

[[Page 1029]]

the middle (``off'') position. If display reads ``04:00'' (4 hours), 
move toggle switch to the left position. Shaker should begin operating.
    11.1.7 After shaker stops, add 100 ml acetone to each sample to 
precipitate polymer. Shake minimum of 5 minutes on shaker--Vistalon 
sample may not have fully dissolved; nevertheless, for purposes of 
consistency, 4 hours is the agreed-upon dissolving time.
    11.1.8 Using a 5-ml glass Luer-lock syringe and Acrodisc filter, 
filter some of the supernatant liquid into an autosampler vial; crimp 
the vial and load it into the GC autosampler for analysis (section 11.2 
of this method)--The samples are filtered to prevent polymer buildup in 
the GC. Clean the syringes in toluene.
    11.1.9 Decant remaining supernatant into a hydrocarbon waste sink, 
being careful not to discard any of the polymer. Place bottle of 
precipitate into the steam oven and dry for six hours--Some grades of 
Vistalon produce very small particles in the precipitate, thus making 
complete decanting impossible without discarding some polymer. In this 
case, decant as much as possible and put into the oven as is, allowing 
the oven to drive off remaining supernatant (this practice is avoided 
for environmental reasons). WARNING: OVEN IS HOT--110 [deg]C (230 
[deg]F).
    11.1.10 Cool, weigh and record final weight of bottle.
    11.2 GC ANALYSIS
    11.2.1 Initiate the CALS computer channel.
    11.2.2 Enter the correct instrument method into the GC's integrator.
    11.2.3 Load sample vial(s) into autosampler.
    11.2.4 Start the integrator.
    11.2.5 When analysis is complete, plot CALS run to check baseline 
skim.

                   12.0 Data Analysis and Calculations

    12.1 Add the concentrations of the hexane peaks as they appear on 
the CALS printout. Do not include the benzene peak in the sum.
    12.2 Subtract any hexane interferences found in the PDS (see section 
7.5.6 of this method); record the result.
    12.3 Note the termonomer concentration on the CALS printout. 
Subtract any termonomer interference found in the PDS and record this 
result in a ``% termonomer by GC'' column in a logbook.
    12.4 Record the area (from CALS printout) of the heptane internal 
standard peak in a ``C7 area'' column in the logbook. This helps track 
instrument performance over the long term.
    12.5 After obtaining the final dry weight of polymer used (Section 
11.1.10 of this method), record that result in a ``dry wt.'' column of 
the logbook (for oil extended polymer, the amount of oil extracted is 
added to the dry rubber weight).
    12.6 Divide the %C6 by the dry weight to obtain the total PHR hexane 
in crumb. Similarly, divide the % termonomer by the dry weight to obtain 
the total PHR termonomer in crumb. Note that PHR is an abbreviation for 
``parts per hundred''. Record both the hexane and termonomer results in 
the logbook.
    12.7 Correct all results by the recovery efficiency value (R).

                         13.0 Method Performance

    13.1 The method has been shown to provide 100% recovery of the 
hexane analyte. The method was found to give a 6% relative standard 
deviation when the same six portions of the same sample were carried 
through the procedure. Note: These values are examples; each sample 
type, as specified in Section 9.3, must be tested for sample recovery.

                        14.0 Pollution Prevention

    14.1 Dispose of all hydrocarbon liquids in the appropriate disposal 
sink system; never pour hydrocarbons down a water sink.
    14.2 As discussed in section 11.1.9 of this method, the analyst can 
minimize venting hydrocarbon vapor to the atmosphere by decanting as 
much hydrocarbon liquid as possible before oven drying.

                          15.0 Waste Mamagement

    15.1 The Technician conducting the analysis should follow the proper 
waste management practices for their laboratory location.

                           Gas Chromatography

                        1.0 Scope and Application

    1.1 This method describes a procedure for the determination of 
residual hexane in EPDM wet crumb rubber in the 0.01--2% range by 
solvent extraction of the hexane followed by gas chromatographic 
analysis where the hexane is detected by flame ionization and quantified 
via an internal standard.
    1.2 This method may involve hazardous materials operations and 
equipment. This method does not purport to address all the safety 
problems associated with it use, if any. It is the responsibility of the 
user to consult and establish appropriate safety and health practices 
and determine the applicability of regulatory limitations prior to use.

[[Page 1030]]

                               2.0 Summary

    2.1 Residual hexane contained in wet pieces of EPDM polymer is 
extracted with MIBK. A known amount of an internal standard (IS) is 
added to the extract which is subsequently analyzed via gas 
chromatography where the hexane and IS are separated and detected 
utilizing a megabore column and flame ionization detection (FID). From 
the response to the hexane and the IS, the amount of hexane in the EPDM 
polymer is calculated.

                             3.0 Definitions

    3.1 Hexane--refers to n-hexane
    3.2 Heptane--refers to n-heptane
    3.3 MIBK--methyl isobutyl ketone (4 methyl 2--Pentanone)

                            4.0 Interferences

    4.1 Material eluting at or near the hexane and/or the IS will cause 
erroneous results. Prior to extraction, solvent blanks must be analyzed 
to confirm the absence of interfering peaks.

                               5.0 Safety

    7.1 Reagent grade Methyl-Iso-Butyl-Ketone (MIBK)
    7.2 n-heptane, 99% + purity
    7.3 n-hexane, 99% + purity

                          8.0 Sample Collection

    8.1 Trap a sample of the EPDM crumb slurry in the sampling 
apparatus. Allow the crumb slurry to circulate through the sampling 
apparatus for 5 minutes; then close off the values at the bottom and top 
of the sampling apparatus, trapping the crumb slurry. Run cooling water 
through the water jacket for a minimum of 30 minutes. Expel the cooled 
crumb slurry into a sample catching basket. If the crumb does not fall 
by gravity, force it out with demineralized water or nitrogen. Send the 
crumb slurry to the lab for analysis.

                           9.0 Quality Control

    9.1 The Royalene crumb sample is extracted three times with MIBK 
containing an internal standard. The hexane from each extraction is 
added together to obtain a total hexane content. The percent hexane in 
the first extraction is then calculated and used as the recovery factor 
for the analysis.
    9.2 Follow this test method through section 11.4 of the method. 
After removing the sample of the first extraction to be run on the gas 
chromatograph, drain off the remainder of the extraction solvent, 
retaining the crumb sample in the sample jar. Rinse the crumb with 
demineralized water to remove any MIBK left on the surface of the crumb. 
Repeat the extraction procedure with fresh MIBK with internal standard 
two more times.
    9.3 After the third extraction, proceed to section 11.5 of this 
method and obtain the percent hexane in each extraction. Use the sample 
weight obtained in section 12.1 of this method to calculate the percent 
hexane in each of the extracts.
    9.4 Add the percent hexane obtained from the three extractions for a 
total percent hexane in the sample.
    9.5 Use the following equations to determine the recovery factor 
(R):
    % Recovery of the first extraction=(% hexane in the first extract/
total % hexane)x100
    Recovery Factor (R)=(% Hexane Recovered in the first extract)/100

                            10.0 Calibration

    10.1 Preparation of Internal Standard (IS) solution:
    Accuracy weigh 30 grams of n-heptane into a 1000 ml volumetric 
flask. Dilute to the mark with reagent grade MIBK. Label this Solution 
``A''. Pipette 100 mls. of Solution A into a 4 liter volumetric flask. 
Fill the flask to the mark with reagent MIBK. Label this Solution ``B''. 
Solution ``B'' will have a concentration of 0.75 mg/ml of heptane.
    10.2 Preparation of Hexane Standard Solution (HS):
    Using a 50 uL syringe, weigh by difference, 20 mg of n-hexane into a 
50 ml volumetric flask containing approximately 40 ml of Solution B. 
Fill the flask to the mark with Solution B and mix well.
    10.3 Conditions for GC analysis of standards and samples:
    Temperature:
    Initial=40 [deg]C
    Final=150 [deg]C
    Injector=160 [deg]C
    Detector=280 [deg]C
    Program Rate=5.0 [deg]C/min


[[Page 1031]]


    Initial Time=5 minutes Final Time=6 minutes
    Flow Rate=5.0 ml/min
    Sensitivity=detector response must be adjusted to keep the hexane 
and IS on scale.
    10.4 Fill an autosampler vial with the HS, analyze it three times 
and calculate a Hexane Relative Response Factor (RF) as follows:

    RF=(AIS x CHS x PHS)/
(AHS x CIS x PIS) (1)

    Where:
    AIS=Area of IS peak (Heptane)
    AHS=Area of peak (Hexane Standard)
    CHS=Mg of Hexane/50 ml HS
    CIS=Mg of Heptane/50 ml IS Solution B
    PIS=Purity of the IS n-heptane
    PHS=Purity of the HS n-hexane

                             11.0 Procedure

    11.1 Weight 10 grams of wet crumb into a tared (W1), wide mouth 4 
oz. jar.
    11.2 Pipette 50 ml of Solution B into the jar with the wet crumb 
rubber.
    11.3 Screw the cap on tightly and place it on a shaker for 4 hours.
    11.4 Remove the sample from the shaker and fill an autosampler vial 
with the MIBK extract.
    11.5 Analyze the sample two times.
    11.6 Analyze the HS twice, followed by the samples. Inject the HS 
twice at the end of each 10 samples or at the end of the run.

                            12.0 Calculations

    12.1 Drain off the remainder of the MIBK extract from the polymer in 
the 4 oz. jar. Retain all the polymer in the jar. Place the uncovered 
jar and polymer in a heated vacuum oven until the polymer is dry. 
Reweigh the jar and polymer (W2) and calculate the dried sample weight 
of the polymer as follows:

    Dried SW=W2--W1 (2)

    12.2 Should the polymer be oil extended, pipette 10 ml of the MIBK 
extract into a tared evaporating dish (W1) and evaporate to dryness on a 
steam plate.
    Reweigh the evaporating dish containing the extracted oil (W2). 
Calculate the oil content of the polymer as follows:

    Gram of oil extracted =5 (W2--W1) (3)

% Hexane in polymer=(AsxRFxCISxPIS)/
          (AISxSW) (4)
    Where:
    As=Area of sample hexane sample peak.
    AIS=Area of IS peak in sample.
    CIS=Concentration of IS in 50 ml.
    PIS=Purity of IS.
    SW=Weight of dried rubber after extraction. (For oil extended 
polymer, the amount of oil extracted is added to the dry rubber weight).
    % Corrected Hexane=(% Hexane in Polymer)/R (5)
    R=Recovery factor determined in section 9 of this method.

                         13.0 Method Performance

    13.1 Performance must be determined for each sample type by 
following the procedures in section 9 of this method.

Method 311--Analysis of Hazardous Air Pollutant Compounds in Paints and 
          Coatings by Direct Injection Into a Gas Chromatograph

                        1. Scope and Application

    1.1 Applicability. This method is applicable for determination of 
most compounds designated by the U.S. Environmental Protection Agency as 
volatile hazardous air pollutants (HAP's) (See Reference 1) that are 
contained in paints and coatings. Styrene, ethyl acrylate, and methyl 
methacrylate can be measured by ASTM D 4827-93 or ASTM D 4747-87. 
Formaldehyde can be measured by ASTM PS 9-94 or ASTM D 1979-91. Toluene 
diisocyanate can be measured in urethane prepolymers by ASTM D 3432-89. 
Method 311 applies only to those volatile HAP's which are added to the 
coating when it is manufactured, not to those which may form as the 
coating cures (reaction products or cure volatiles). A separate or 
modified test procedure must be used to measure these reaction products 
or cure volatiles in order to determine the total volatile HAP emissions 
from a coating. Cure volatiles are a significant component of the total 
HAP content of some coatings. The term ``coating'' used in this method 
shall be understood to mean paints and coatings.
    1.2 Principle. The method uses the principle of gas chromatographic 
separation and quantification using a detector that responds to 
concentration differences. Because there are many potential analytical 
systems or sets of operating conditions that may represent useable 
methods for determining the concentrations of the compounds cited in 
Section 1.1 in the applicable matrices, all systems that employ this 
principle, but differ only in details of equipment and operation, may be 
used as alternative methods, provided that the prescribed quality 
control, calibration, and method performance requirements are met. 
Certified product data sheets (CPDS) may also include information 
relevant to the analysis of the coating sample including, but not 
limited to, separation

[[Page 1032]]

column, oven temperature, carrier gas, injection port temperature, 
extraction solvent, and internal standard.

                          2. Summary of Method

    Whole coating is added to dimethylformamide and a suitable internal 
standard compound is added. An aliquot of the sample mixture is injected 
onto a chromatographic column containing a stationary phase that 
separates the analytes from each other and from other volatile compounds 
contained in the sample. The concentrations of the analytes are 
determined by comparing the detector responses for the sample to the 
responses obtained using known concentrations of the analytes.

                       3. Definitions. [Reserved]

                            4. Interferences

    4.1 Coating samples of unknown composition may contain the compound 
used as the internal standard. Whether or not this is the case may be 
determined by following the procedures of Section 11 and deleting the 
addition of the internal standard specified in Section 11.5.3. If 
necessary, a different internal standard may be used.
    4.2 The GC column and operating conditions developed for one coating 
formulation may not ensure adequate resolution of target analytes for 
other coating formulations. Some formulations may contain nontarget 
analytes that coelute with target analytes. If there is any doubt about 
the identification or resolution of any gas chromatograph (GC) peak, it 
may be necessary to analyze the sample using a different GC column or 
different GC operating conditions.
    4.3 Cross-contamination may occur whenever high-level and low-level 
samples are analyzed sequentially. The order of sample analyses 
specified in Section 11.7 is designed to minimize this problem.
    4.4 Cross-contamination may also occur if the devices used to 
transfer coating during the sample preparation process or for injecting 
the sample into the GC are not adequately cleaned between uses. All such 
devices should be cleaned with acetone or other suitable solvent and 
checked for plugs or cracks before and after each use.

                                5. Safety

    5.1 Many solvents used in coatings are hazardous. Precautions should 
be taken to avoid unnecessary inhalation and skin or eye contact. This 
method may involve hazardous materials, operations, and equipment. This 
test method does not purport to 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 to 
determine the applicability of regulatory limitations in regards to the 
performance of this test method.
    5.2 Dimethylformamide is harmful if inhaled or absorbed through the 
skin. The user should obtain relevant health and safety information from 
the manufacturer. Dimethylformamide should be used only with adequate 
ventilation. Avoid contact with skin, eyes, and clothing. In case of 
contact, immediately flush skin or eyes with plenty of water for at 
least 15 minutes. If eyes are affected, consult a physician. Remove and 
wash contaminated clothing before reuse.
    5.3 User's manuals for the gas chromatograph and other related 
equipment should be consulted for specific precautions to be taken 
related to their use.

                        6. Equipment and Supplies

    Note: Certified product data sheets (CPDS) may also include 
information relevant to the analysis of the coating sample including, 
but not limited to, separation column, oven temperature, carrier gas, 
injection port temperature, extraction solvent, and internal standard.

    6.1 Sample Collection.
    6.1.1 Sampling Containers. Dual-seal sampling containers, four to 
eight fluid ounce capacity, should be used to collect the samples. Glass 
sample bottles or plastic containers with volatile organic compound 
(VOC) impermeable walls must be used for corrosive substances (e.g., 
etch primers and certain coating catalysts such as methyl ethyl ketone 
(MEK) peroxide). Sample containers, caps, and inner seal liners must be 
inert to the compounds in the sample and must be selected on a case-by-
case basis.
    6.1.1.1 Other routine sampling supplies needed include waterproof 
marking pens, tubing, scrappers/spatulas, clean rags, paper towels, 
cooler/ice, long handle tongs, and mixing/stirring paddles.
    6.1.2 Personal safety equipment needed includes eye protection, 
respiratory protection, a hard hat, gloves, steel toe shoes, etc.
    6.1.3 Shipping supplies needed include shipping boxes, packing 
material, shipping labels, strapping tape, etc.
    6.1.4 Data recording forms and labels needed include coating data 
sheets and sample can labels.

    Note: The actual requirements will depend upon the conditions 
existing at the source sampled.

    6.2 Laboratory Equipment and Supplies.
    6.2.1 Gas Chromatograph (GC). Any instrument equipped with a flame 
ionization detector and capable of being temperature programmed may be 
used. Optionally, other types of detectors (e.g., a mass spectrometer), 
and any necessary interfaces, may be used provided that the detector 
system

[[Page 1033]]

yields an appropriate and reproducible response to the analytes in the 
injected sample. Autosampler injection may be used, if available.
    6.2.2 Recorder. If available, an electronic data station or 
integrator may be used to record the gas chromatogram and associated 
data. If a strip chart recorder is used, it must meet the following 
criteria: A 1 to 10 millivolt (mV) linear response with a full scale 
response time of 2 seconds or less and a maximum noise level of 
[plusmn]0.03 percent of full scale. Other types of recorders may be used 
as appropriate to the specific detector installed provided that the 
recorder has a full scale response time of 2 seconds or less and a 
maximum noise level of [plusmn]0.03 percent of full scale.
    6.2.3 Column. The column must be constructed of materials that do 
not react with components of the sample (e.g., fused silica, stainless 
steel, glass). The column should be of appropriate physical dimensions 
(e.g., length, internal diameter) and contain sufficient suitable 
stationary phase to allow separation of the analytes. DB-5, DB-Wax, and 
FFAP columns are commonly used for paint analysis; however, it is the 
responsibility of each analyst to select appropriate columns and 
stationary phases.
    6.2.4 Tube and Tube Fittings. Supplies to connect the GC and gas 
cylinders.
    6.2.5 Pressure Regulators. Devices used to regulate the pressure 
between gas cylinders and the GC.
    6.2.6 Flow Meter. A device used to determine the carrier gas flow 
rate through the GC. Either a digital flow meter or a soap film bubble 
meter may be used to measure gas flow rates.
    6.2.7 Septa. Seals on the GC injection port through which liquid or 
gas samples can be injected using a syringe.
    6.2.8 Liquid Charging Devices. Devices used to inject samples into 
the GC such as clean and graduated 1, 5, and 10 microliter ([mu]l) 
capacity syringes.
    6.2.9 Vials. Containers that can be sealed with a septum in which 
samples may be prepared or stored. The recommended size is 25 ml 
capacity. Mininert[reg] valves have been found satisfactory 
and are available from Pierce Chemical Company, Rockford, Illinois.
    6.2.10 Balance. Device used to determine the weights of standards 
and samples. An analytical balance capable of accurately weighing to 
0.0001 g is required.

                        7. Reagents and Standards

    7.1 Purity of Reagents. Reagent grade chemicals shall be used in all 
tests. Unless otherwise specified, all reagents shall conform to the 
specifications of the Committee on Analytical Reagents of the American 
Chemical Society, where such specifications are available. Other grades 
may be used provided it is first ascertained that the reagent is of 
sufficient purity to permit its use without lessening the accuracy of 
determination.
    7.2 Carrier Gas. Helium carrier gas shall have a purity of 99.995 
percent or higher. High purity nitrogen may also be used. Other carrier 
gases that are appropriate for the column system and analyte may also be 
used. Ultra-high purity grade hydrogen gas and zero-grade air shall be 
used for the flame ionization detector.
    7.3 Dimethylformamide (DMF). Solvent for all standards and samples. 
Some other suitable solvent may be used if DMF is not compatible with 
the sample or coelutes with a target analyte.

    Note: DMF may coelute with ethylbenzene or p-xylene under the 
conditions described in the note under Section 6.2.3.

    7.4 Internal Standard Materials. The internal standard material is 
used in the quantitation of the analytes for this method. It shall be 
gas chromatography spectrophotometric quality or, if this grade is not 
available, the highest quality available. Obtain the assay for the 
internal standard material and maintain at that purity during use. The 
recommended internal standard material is 1-propanol; however, selection 
of an appropriate internal standard material for the particular coating 
and GC conditions used is the responsibility of each analyst.
    7.5 Reference Standard Materials. The reference standard materials 
are the chemicals cited in Section 1.1 which are of known identity and 
purity and which are used to assist in the identification and 
quantification of the analytes of this method. They shall be the highest 
quality available. Obtain the assays for the reference standard 
materials and maintain at those purities during use.
    7.6 Stock Reference Standards. Stock reference standards are 
dilutions of the reference standard materials that may be used on a 
daily basis to prepare calibration standards, calibration check 
standards, and quality control check standards. Stock reference 
standards may be prepared from the reference standard materials or 
purchased as certified solutions.
    7.6.1 Stock reference standards should be prepared in 
dimethylformamide for each analyte expected in the coating samples to be 
analyzed. The concentrations of analytes in the stock reference 
standards are not specified but must be adequate to prepare the 
calibration standards required in the method. A stock reference standard 
may contain more than one analyte provided all analytes are chemically 
compatible and no analytes coelute. The actual concentrations prepared 
must be known to within 0.1 percent (e.g., 0.1000 [plusmn] 0.0001 g/g 
solution). The following procedure is suggested. Place about 35 ml of 
dimethylformamide into a

[[Page 1034]]

tared ground-glass stoppered 50 ml volumetric flask. Weigh the flask to 
the nearest 0.1 mg. Add 12.5 g of the reference standard material and 
reweigh the flask. Dilute to volume with dimethylformamide and reweigh. 
Stopper the flask and mix the contents by inverting the flask several 
times. Calculate the concentration in grams per gram of solution from 
the net gain in weights, correcting for the assayed purity of the 
reference standard material.

    Note: Although a glass-stoppered volumetric flask is convenient, any 
suitable glass container may be used because stock reference standards 
are prepared by weight.

    7.6.2 Transfer the stock reference standard solution into one or 
more Teflon-sealed screw-cap bottles. Store, with minimal headspace, at 
-10 [deg]C to 0 [deg]C and protect from light.
    7.6.3 Prepare fresh stock reference standards every six months, or 
sooner if analysis results from daily calibration check standards 
indicate a problem. Fresh stock reference standards for very volatile 
HAP's may have to be prepared more frequently.
    7.7 Calibration Standards. Calibration standards are used to 
determine the response of the detector to known amounts of reference 
material. Calibration standards must be prepared at a minimum of three 
concentration levels from the stock reference standards (see Section 
7.6). Prepare the calibration standards in dimethylformamide (see 
Section 7.3). The lowest concentration standard should contain a 
concentration of analyte equivalent either to a concentration of no more 
than 0.01% of the analyte in a coating or to a concentration that is 
lower than the actual concentration of the analyte in the coating, 
whichever concentration is higher. The highest concentration standard 
should contain a concentration of analyte equivalent to slightly more 
than the highest concentration expected for the analyte in a coating. 
The remaining calibration standard should contain a concentration of 
analyte roughly at the midpoint of the range defined by the lowest and 
highest concentration calibration standards. The concentration range of 
the standards should thus correspond to the expected range of analyte 
concentrations in the prepared coating samples (see Section 11.5). Each 
calibration standard should contain each analyte for detection by this 
method expected in the actual coating samples (e.g., some or all of the 
compounds listed in Section 1.1 may be included). Each calibration 
standard should also contain an appropriate amount of internal standard 
material (response for the internal standard material is within 25 to 75 
percent of full scale on the attenuation setting for the particular 
reference standard concentration level). Calibration Standards should be 
stored for 1 week only in sealed vials with minimal headspace. If the 
stock reference standards were prepared as specified in Section 7.6, the 
calibration standards may be prepared by either weighing each addition 
of the stock reference standard or by adding known volumes of the stock 
reference standard and calculating the mass of the standard reference 
material added. Alternative 1 (Section 7.7.1) specifies the procedure to 
be followed when the stock reference standard is added by volume. 
Alternative 2 (Section 7.7.2) specifies the procedure to be followed 
when the stock reference standard is added by weight.

    Note: To assist with determining the appropriate amount of internal 
standard to add, as required here and in other sections of this method, 
the analyst may find it advantageous to prepare a curve showing the area 
response versus the amount of internal standard injected into the GC.

    7.7.1 Preparation Alternative 1. Determine the amount of each stock 
reference standard and dimethylformamide solvent needed to prepare 
approximately 25 ml of the specific calibration concentration level 
desired. To a tared 25 ml vial that can be sealed with a crimp-on or 
Mininert[reg] valve, add the total amount of 
dimethylformamide calculated to be needed. As quickly as practical, add 
the calculated amount of each stock reference standard using new pipets 
(or pipet tips) for each stock reference standard. Reweigh the vial and 
seal it. Using the known weights of the standard reference materials per 
ml in the stock reference standards, the volumes added, and the total 
weight of all reagents added to the vial, calculate the weight percent 
of each standard reference material in the calibration standard 
prepared. Repeat this process for each calibration standard to be 
prepared.
    7.7.2 Preparation Alternative 2. Determine the amount of each stock 
reference standard and dimethylformamide solvent needed to prepare 
approximately 25 ml of the specific calibration concentration level 
desired. To a tared 25 ml vial that can be sealed with a crimp-on or 
Mininert[reg] valve, add the total amount of 
dimethylformamide calculated to be needed. As quickly as practical, add 
the calculated amount of a stock reference standard using a new pipet 
(or pipet tip) and reweigh the vial. Repeat this process for each stock 
reference standard to be added. Seal the vial after obtaining the final 
weight. Using the known weight percents of the standard reference 
materials in the stock reference standards, the weights of the stock 
reference standards added, and the total weight of all reagents added to 
the vial, calculate the weight percent of each standard reference 
material in the calibration standard prepared. Repeat this process for 
each calibration standard to be prepared.

[[Page 1035]]

       8. Sample Collection, Preservation, Transport, and Storage

    8.1 Copies of material safety data sheets (MSDS's) for each sample 
should be obtained prior to sampling. The MSDS's contain information on 
the ingredients, and physical and chemical properties data. The MSDS's 
also contain recommendations for proper handling or required safety 
precautions. Certified product data sheets (CPDS) may also include 
information relevant to the analysis of the coating sample including, 
but not limited to, separation column, oven temperature, carrier gas, 
injection port temperature, extraction solvent, and internal standard.
    8.2 A copy of the blender's worksheet can be requested to obtain 
data on the exact coating being sampled. A blank coating data sheet form 
(see Section 18) may also be used. The manufacturer's formulation 
information from the product data sheet should also be obtained.
    8.3 Prior to sample collection, thoroughly mix the coating to ensure 
that a representative, homogeneous sample is obtained. It is preferred 
that this be accomplished using a coating can shaker or similar device; 
however, when necessary, this may be accomplished using mechanical 
agitation or circulation systems.
    8.3.1 Water-thinned coatings tend to incorporate or entrain air 
bubbles if stirred too vigorously; mix these types of coatings slowly 
and only as long as necessary to homogenize.
    8.3.2 Each component of multicomponent coatings that harden when 
mixed must be sampled separately. The component mix ratios must be 
obtained at the facility at the time of sampling and submitted to the 
analytical laboratory.
    8.4 Sample Collection. Samples must be collected in a manner that 
prevents or minimizes loss of volatile components and that does not 
contaminate the coating reservoir. A suggested procedure is as follows. 
Select a sample collection container which has a capacity at least 25 
percent greater than the container in which the sample is to be 
transported. Make sure both sample containers are clean and dry. Using 
clean, long-handled tongs, turn the sample collection container upside 
down and lower it into the coating reservoir. The mouth of the sample 
collection container should be at approximately the midpoint of the 
reservoir (do not take the sample from the top surface). Turn the sample 
collection container over and slowly bring it to the top of the coating 
reservoir. Rapidly pour the collected coating into the sample container, 
filling it completely. It is important to fill the sample container 
completely to avoid any loss of volatiles due to volatilization into the 
headspace. Return any unused coating to the reservoir or dispose as 
appropriate.

    Note: If a company requests a set of samples for its own analysis, a 
separate set of samples, using new sample containers, should be taken at 
the same time.

    8.5 Once the sample is collected, place the sample container on a 
firm surface and insert the inner seal in the container by placing the 
seal inside the rim of the container, inverting a screw cap, and 
pressing down on the screw cap which will evenly force the inner seal 
into the container for a tight fit. Using clean towels or rags, remove 
all residual coating material from the outside of the sample container 
after inserting the inner seal. Screw the cap onto the container.
    8.5.1 Affix a sample label (see Section 18) clearly identifying the 
sample, date collected, and person collecting the sample.
    8.5.2 Prepare the sample for transportation to the laboratory. The 
sample should be maintained at the coating's recommended storage 
temperature specified on the Material Safety Data Sheet, or, if no 
temperature is specified, the sample should be maintained within the 
range of 5 [deg]C to 38 [deg]C.
    8.9 The shipping container should adhere to U.S. Department of 
Transportation specification DOT 12-B. Coating samples are considered 
hazardous materials; appropriate shipping procedures should be followed.

                           9. Quality Control

    9.1 Laboratories using this method should operate a formal quality 
control program. The minimum requirements of the program should consist 
of an initial demonstration of laboratory capability and an ongoing 
analysis of blanks and quality control samples to evaluate and document 
quality data. The laboratory must maintain records to document the 
quality of the data generated. When results indicate atypical method 
performance, a quality control check standard (see Section 9.4) must be 
analyzed to confirm that the measurements were performed in an in-
control mode of operation.
    9.2 Before processing any samples, the analyst must demonstrate, 
through analysis of a reagent blank, that there are no interferences 
from the analytical system, glassware, and reagents that would bias the 
sample analysis results. Each time a set of analytical samples is 
processed or there is a change in reagents, a reagent blank should be 
processed as a safeguard against chronic laboratory contamination. The 
blank samples should be carried through all stages of the sample 
preparation and measurement steps.
    9.3 Required instrument quality control parameters are found in the 
following sections:
    9.3.1 Baseline stability must be demonstrated to be [le]5 percent of 
full scale using the procedures given in Section 10.1.

[[Page 1036]]

    9.3.2 The GC calibration is not valid unless the retention time (RT) 
for each analyte at each concentration is within [plusmn]0.05 min of the 
retention time measured for that analyte in the stock standard.
    9.3.3 The retention time (RT) of any sample analyte must be within 
[plusmn]0.05 min of the average RT of the analyte in the calibration 
standards for the analyte to be considered tentatively identified.
    9.3.4 The GC system must be calibrated as specified in Section 10.2.
    9.3.5 A one-point daily calibration check must be performed as 
specified in Section 10.3.
    9.4 To establish the ability to generate results having acceptable 
accuracy and precision, the analyst must perform the following 
operations.
    9.4.1 Prepare a quality control check standard (QCCS) containing 
each analyte expected in the coating samples at a concentration expected 
to result in a response between 25 percent and 75 percent of the limits 
of the calibration curve when the sample is prepared as described in 
Section 11.5. The QCCS may be prepared from reference standard materials 
or purchased as certified solutions. If prepared in the laboratory, the 
QCCS must be prepared independently from the calibration standards.
    9.4.2 Analyze three aliquots of the QCCS according to the method 
beginning in Section 11.5.3 and calculate the weight percent of each 
analyte using Equation 1, Section 12.
    9.4.3 Calculate the mean weight percent (X) for each analyte from 
the three results obtained in Section 9.4.2.
    9.4.4 Calculate the percent accuracy for each analyte using the 
known concentrations (Ti) in the QCCS using Equation 3, Section 12.
    9.4.5 Calculate the percent relative standard deviation (percent 
RSD) for each analyte using Equation 7, Section 12, substituting the 
appropriate values for the relative response factors (RRF's) in said 
equation.
    9.4.6 If the percent accuracy (Section 9.4.4) for all analytes is 
within the range 90 percent to 110 percent and the percent RSD (Section 
9.4.5) for all analytes is [le]20 percent, system performance is 
acceptable and sample analysis may begin. If these criteria are not met 
for any analyte, then system performance is not acceptable for that 
analyte and the test must be repeated for those analytes only. Repeated 
failures indicate a general problem with the measurement system that 
must be located and corrected. In this case, the entire test, beginning 
at Section 9.4.1, must be repeated after the problem is corrected.
    9.5 Great care must be exercised to maintain the integrity of all 
standards. It is recommended that all standards be stored at -10 [deg]C 
to 0 [deg]C in screw-cap amber glass bottles with Teflon liners.
    9.6 Unless otherwise specified, all weights are to be recorded 
within 0.1 mg.

                  10. Calibration and Standardization.

    10.1 Column Baseline Drift. Before each calibration and series of 
determinations and before the daily calibration check, condition the 
column using procedures developed by the laboratory or as specified by 
the column supplier. Operate the GC at initial (i.e., before sample 
injection) conditions on the lowest attenuation to be used during sample 
analysis. Adjust the recorder pen to zero on the chart and obtain a 
baseline for at least one minute. Initiate the GC operating cycle that 
would be used for sample analysis. On the recorder chart, mark the pen 
position at the end of the simulated sample analysis cycle. Baseline 
drift is defined as the absolute difference in the pen positions at the 
beginning and end of the cycle in the direction perpendicular to the 
chart movement. Calculate the percent baseline drift by dividing the 
baseline drift by the chart width representing full-scale deflection and 
multiply the result by 100.
    10.2 Calibration of GC. Bring all stock standards and calibration 
standards to room temperature while establishing the GC at the 
determined operating conditions.
    10.2.1 Retention Times (RT's) for Individual Compounds.

    Note: The procedures of this subsection are required only for the 
initial calibration. However, it is good laboratory practice to follow 
these procedures for some or all analytes before each calibration. The 
procedures were written for chromatograms output to a strip chart 
recorder. More modern instruments (e.g., integrators and electronic data 
stations) determine and print out or display retention times 
automatically.

    The RT for each analyte should be determined before calibration. 
This provides a positive identification for each peak observed from the 
calibration standards. Inject an appropriate volume (see Note in Section 
11.5.2) of one of the stock reference standards into the gas 
chromatograph and record on the chart the pen position at the time of 
the injection (see Section 7.6.1). Dilute an aliquot of the stock 
reference standard as required in dimethylformamide to achieve a 
concentration that will result in an on-scale response. Operate the gas 
chromatograph according to the determined procedures. Select the peak(s) 
that correspond to the analyte(s) [and internal standard, if used] and 
measure the retention time(s). If a chart recorder is used, measure the 
distance(s) on the chart from the injection point to the peak maxima. 
These distances, divided by the chart speed, are defined as the RT's of 
the analytes in question. Repeat this process for each of the stock 
reference standard solutions.


[[Page 1037]]


    Note: If gas chromatography with mass spectrometer detection (GC-MS) 
is used, a stock reference standard may contain a group of analytes, 
provided all analytes are adequately separated during the analysis. Mass 
spectral library matching can be used to identify the analyte associated 
with each peak in the gas chromatogram. The retention time for the 
analyte then becomes the retention time of its peak in the chromatogram.

    10.2.2 Calibration. The GC must be calibrated using a minimum of 
three concentration levels of each potential analyte. (See Section 7.7 
for instructions on preparation of the calibration standards.) Beginning 
with the lowest concentration level calibration standard, carry out the 
analysis procedure as described beginning in Section 11.7. Repeat the 
procedure for each progressively higher concentration level until all 
calibration standards have been analyzed.
    10.2.2.1 Calculate the RT's for the internal standard and for each 
analyte in the calibration standards at each concentration level as 
described in Section 10.2.1. The RT's for the internal standard must not 
vary by more than 0.10 minutes. Identify each analyte by comparison of 
the RT's for peak maxima to the RT's determined in Section 10.2.1.
    10.2.2.2 Compare the retention times (RT's) for each potential 
analyte in the calibration standards for each concentration level to the 
retention times determined in Section 10.2.1. The calibration is not 
valid unless all RT's for all analytes meet the criteria given in 
Section 9.3.2.
    10.2.2.3 Tabulate the area responses and the concentrations for the 
internal standard and each analyte in the calibration standards. 
Calculate the response factor for the internal standard 
(RFis) and the response factor for each compound relative to 
the internal standard (RRF) for each concentration level using Equations 
5 and 6, Section 12.
    10.2.2.4 Using the RRF's from the calibration, calculate the percent 
relative standard deviation (percent RSD) for each analyte in the 
calibration standard using Equation 7, Section 12. The percent RSD for 
each individual calibration analyte must be less than 15 percent. This 
criterion must be met in order for the calibration to be valid. If the 
criterion is met, the mean RRF's determined above are to be used until 
the next calibration.
    10.3 Daily Calibration Checks. The calibration curve (Section 
10.2.2) must be checked and verified at least once each day that samples 
are analyzed. This is accomplished by analyzing a calibration standard 
that is at a concentration near the midpoint of the working range and 
performing the checks in Sections 10.3.1, 10.3.2, and 10.3.3.
    10.3.1 For each analyte in the calibration standard, calculate the 
percent difference in the RRF from the last calibration using Equation 
8, Section 12. If the percent difference for each calibration analyte is 
less than 10 percent, the last calibration curve is assumed to be valid. 
If the percent difference for any analyte is greater than 5 percent, the 
analyst should consider this a warning limit. If the percent difference 
for any one calibration analyte exceeds 10 percent, corrective action 
must be taken. If no source of the problem can be determined after 
corrective action has been taken, a new three-point (minimum) 
calibration must be generated. This criterion must be met before 
quantitative analysis begins.
    10.3.2 If the RFis for the internal standard changes by 
more than [plusmn]20 percent from the last daily calibration check, the 
system must be inspected for malfunctions and corrections made as 
appropriate.
    10.3.3 The retention times for the internal standard and all 
calibration check analytes must be evaluated. If the retention time for 
the internal standard or for any calibration check analyte changes by 
more than 0.10 min from the last calibration, the system must be 
inspected for malfunctions and corrections made as required.

                              11. Procedure

    11.1 All samples and standards must be allowed to warm to room 
temperature before analysis. Observe the given order of ingredient 
addition to minimize loss of volatiles.
    11.2 Bring the GC system to the determined operating conditions and 
condition the column as described in Section 10.1.

    Note: The temperature of the injection port may be an especially 
critical parameter.Information about the proper temperature may be found 
on the CPDS.

    11.3 Perform the daily calibration checks as described in Section 
10.3. Samples are not to be analyzed until the criteria in Section 10.3 
are met.
    11.4 Place the as-received coating sample on a paint shaker, or 
similar device, and shake the sample for a minimum of 5 minutes to 
achieve homogenization.
    11.5 Note: The steps in this section must be performed rapidly and 
without interruption to avoid loss of volatile organics. These steps 
must be performed in a laboratory hood free from solvent vapors. All 
weights must be recorded to the nearest 0.1 mg.
    11.5.1 Add 16 g of dimethylformamide to each of two tared vials (A 
and B) capable of being septum sealed.
    11.5.2 To each vial add a weight of coating that will result in the 
response for the major constituent being in the upper half of the linear 
range of the calibration curve.

    Note: The magnitude of the response obviously depends on the amount 
of sample injected into the GC as specified in Section 11.8. This volume 
must be the same as used

[[Page 1038]]

for preparation of the calibration curve, otherwise shifts in compound 
retention times may occur. If a sample is prepared that results in a 
response outside the limits of the calibration curve, new samples must 
be prepared; changing the volume injected to bring the response within 
the calibration curve limits is not permitted.

    11.5.3 Add a weight of internal standard to each vial (A and B) that 
will result in the response for the internal standard being between 25 
percent and 75 percent of the linear range of the calibration curve.
    11.5.4 Seal the vials with crimp-on or Mininert septum 
seals.
    11.6 Shake the vials containing the prepared coating samples for 60 
seconds. Allow the vials to stand undisturbed for ten minutes. If solids 
have not settled out on the bottom after 10 minutes, then centrifuge at 
1,000 rpm for 5 minutes. The analyst also has the option of injecting 
the sample without allowing the solids to settle.
    11.7 Analyses should be conducted in the following order: daily 
calibration check sample, method blank, up to 10 injections from sample 
vials (i.e., one injection each from up to five pairs of vials, which 
corresponds to analysis of 5 coating samples).
    11.8 Inject the prescribed volume of supernatant from the 
calibration check sample, the method blank, and the sample vials onto 
the chromatographic column and record the chromatograms while operating 
the system under the specified operating conditions.
    Note: The analyst has the option of injecting the unseparated 
sample.

                   12. Data Analysis and Calculations

    12.1 Qualitative Analysis. An analyte (e.g., those cited in Section 
1.1) is considered tentatively identified if two criteria are satisfied: 
(1) elution of the sample analyte within [plusmn]0.05 min of the average 
GC retention time of the same analyte in the calibration standard; and 
(2) either (a) confirmation of the identity of the compound by spectral 
matching on a gas chromatograph equipped with a mass selective detector 
or (b) elution of the sample analyte within [plusmn]0.05 min of the 
average GC retention time of the same analyte in the calibration 
standard analyzed on a dissimilar GC column.
    12.1.1 The RT of the sample analyte must meet the criteria specified 
in Section 9.3.3.
    12.1.2 When doubt exists as to the identification of a peak or the 
resolution of two or more components possibly comprising one peak, 
additional confirmatory techniques (listed in Section 12.1) must be 
used.
    12.2 Quantitative Analysis. When an analyte has been identified, the 
quantification of that compound will be based on the internal standard 
technique.
    12.2.1 A single analysis consists of one injection from each of two 
sample vials (A and B) prepared using the same coating. Calculate the 
concentration of each identified analyte in the sample as follows:
[GRAPHIC] [TIFF OMITTED] TR07DE95.003

    12.2.2 Report results for duplicate analysis (sample vials A and B) 
without correction.
    12.3 Precision Data. Calculate the percent difference between the 
measured concentrations of each analyte in vials A and B as follows.
    12.3.1 Calculate the weight percent of the analyte in each of the 
two sample vials as described in Section 12.2.1.
    12.3.2 Calculate the percent difference for each analyte as:

Section 9.4) as follows:
[GRAPHIC] [TIFF OMITTED] TR07DE95.005

where Xx is the mean measured value and Tx is the 
known true value of the analyte in the QCCS.
    12.5 Obtain retention times (RT's) from data station or integrator 
or, for chromatograms from a chart recorder, calculate the RT's for 
analytes in the calibration standards (See Section 10.2.2.2) as follows:
[GRAPHIC] [TIFF OMITTED] TR07DE95.006

    12.6 Calculate the response factor for the internal standard (See 
Section 10.2.2.3) as follows:
[GRAPHIC] [TIFF OMITTED] TR07DE95.007

where:
    Ais = Area response of the internal standard.
    Cis = Weight percent of the internal standard.
    12.7 Calculate the relative response factors for analytes in the 
calibration standards (See Section 10.2.2.3) as follows:
where:
[GRAPHIC] [TIFF OMITTED] TR07DE95.008

    RRFx = Relative response factor for an individual 
analyte.
    Ax = Area response of the analyte being measured.
    Cx = Weight percent of the analyte being measured.
    12.8 Calculate the percent relative standard deviation of the 
relative response factors for analytes in the calibration standards (See 
Section 10.2.2.4) as follows:
[GRAPHIC] [TIFF OMITTED] TR07DE95.009

    12.9 Calculate the percent difference in the relative response 
factors between the calibration curve and the daily calibration checks 
(See Section 10.3) as follows:

    16. Waste Management
    16.1 The coating samples and laboratory standards and reagents may 
contain compounds which require management as hazardous waste. It is the 
laboratory's responsibility to ensure all wastes are managed in 
accordance with all applicable laws and regulations.
    16.2 To avoid excessive laboratory waste, obtain only enough sample 
for laboratory analysis.
    16.3 It is recommended that discarded waste coating solids, used 
rags, used paper towels, and other nonglass or nonsharp waste materials 
be placed in a plastic bag before disposal. A separate container, 
designated ``For Sharp Objects Only,'' is recommended for collection of 
discarded glassware and other sharp-edge items used in the laboratory. 
It is recommended that unused or excess samples and reagents be placed 
in a solvent-resistant plastic or metal container with a lid or cover 
designed for flammable liquids. This container should not be stored in 
the area where analytical work is performed. It is recommended that a 
record be kept of all compounds placed in the container for 
identification of the contents upon disposal.

Method 312A--Determination of Styrene in Latex Styrene-Butadiene Rubber, 
                       Through Gas Chromatography

                        1. Scope and Application

    1.1 This method describes a procedure for determining parts per 
million (ppm) styrene monomer (CAS No. 100-42-5) in aqueous samples, 
including latex samples and styrene stripper water.
    1.2 The sample is separated in a gas chromatograph equipped with a 
packed column and a flame ionization detector.

                          2.0 Summary of Method

    2.1 This method utilizes a packed column gas chromatograph with a 
flame ionization detector to determine the concentration of residual 
styrene in styrene butadiene rubber (SBR) latex samples.

                             3.0 Definitions

    3.1 The definitions are included in the text as needed.

                            4.0 Interferences

    4.1 In order to reduce matrix effects and emulsify the styrene, 
similar styrene free latex is added to the internal standard. There are 
no known interferences.
    4.2 The operating parameters are selected to obtain resolution 
necessary to determine styrene monomer concentrations in latex.

                               5.0 Safety

    5.1 It is the responsibility of the user of this procedure to

                           9.0 Quality Control

    9.1 The laboratory is required to operate a formal quality control 
program. This consists of an initial demonstration of the capability of 
the method as well as ongoing analysis of standards, blanks, and spiked 
samples to demonstrate continued performance.
    9.1.1 When the method is first set up, a calibration is run and the 
recovery efficiency for each type of sample must be determined.
    9.1.2 If new types of samples are being analyzed, then recovery 
efficiency for each new type of sample must be determined. New type 
includes any change, such as polymer type, physical form or a 
significant change in the composition of the matrix.
    9.2 Recovery efficiency must be determined once for each sample type 
and whenever modifications are made to the method.
    9.2.1 In determining the recovery efficiency, the quadruplet 
sampling system shall be used. Six sets of samples (for a total of 24) 
shall be taken. In each quadruplet set, half of the samples (two out of 
the four) shall be spiked with styrene.
    9.2.2 Prepare the samples as described in section 8 of this method. 
To the vials labeled ``spiked'', add a known amount of styrene that is 
expected to be present in the latex.
    9.2.3 Run the spiked and unspiked samples in the normal manner. 
Record the concentrations of styrene reported for each pair of spiked 
and unspiked samples with the same vial number.
    9.2.4 For each hydrocarbon, calculate the average recovery 
efficiency (R) using the following equation:

    R=[Sigma](Rn)/12
    Where: n = sample number
    Rn=(Ms-Mu)/S
    Ms=total mass of compound (styrene) measured in spiked 
sample ([mu]g)
    Mu=total mass of compound (styrene) measured in unspiked 
sample ([mu]g)
    S=theoretical mass of compound (styrene) spiked into sample ([mu]g)
    R=fraction of spiked compound (styrene) recovered

    9.2.5 A different R value should be obtained for each sample type. A 
value of R between 0.70 and 1.30 is acceptable.
    9.2.6 R is used to correct all reported results for each compound by 
dividing the measured results of each compound by the R for that 
compound for the same sample type.

                            10.0 Calibration

    A styrene control sample will be tested weekly to confirm the FID 
response and calibration.

    10.1 Using the Styrene Certification Solution prepared in 7.8.1, 
perform test analysis as described in 7.8.2 using the equation in 
7.8.2.3 to calculate results.
    10.2 Calculate the weight of styrene in the styrene control sample 
using the following equation:

    Wsty=(Fx xAsty 
xWis)Ais

    The instrument can be considered calibrated if the weight of the 
styrene analyzed is within range of 0.00097--0.00103gms.

                             11.0 Procedure

    11.1 Using an auto pipet, add 25ml of Internal Standard Solution to 
a 4 oz. wide-mouth bottle.
    11.2 Using a calibrated auto pipet, add 5.0 [plusmn] 0.01g latex to 
the bottle containing the 25ml of Internal Standard Solution.
    11.3 Cap the bottle and place on the wrist action shaker. Shake the 
sample for a minimum of five minutes using the timer on the shaker. 
Remove from shaker.
    11.4 Using a disposable pipet, fill the 2ml sample vial with the 
clear alcohol extract. (If the extract is not clear, it should be 
filtered using a funnel and filter paper.) Cap and seal the vial.
    11.5 Place the sample in the autosampler tray and start the GC and 
Integrator. The sample will be injected into the GC by the auto-
injector, and the Integrator will print the results.

                            12.0 Calculations

    12.1 The integrator is programmed to do the following calculation at 
the end of the analysis:

    %ResidualStyrene=(Ax XWis)/(Ais 
XWx)XFx X100

    Where:
    Ax=Peak area of styrene
    Ais=Peak area of internal standard
    Wx=Weight of sample = 5g
    Wis=Weight of internal std. = 0.00125g
    Fx=Analyzed response factor = 1.0

    12.2 The response factor is determined by analyzing a solution of 
0.02g of styrene and

[[Page 1051]]

0.02g of alpha methyl styrene in 100ml of 2-propanol. Calculate the 
factor by the following equation:

    Fx=(Wx xAis)/(Wis 
xAx)

    Where:
    Wx=Weight of styrene
    Ax=Peak area of styrene
    Wis=Weight of alpha methyl styrene
    Ais=Peak area of alpha methyl styrene

                         13.0 Method Performance

   Method 313A--Determination of Residual Hydrocarbons in Rubber Crumb

                        1.0 Scope and Application

    1.1 This method determines residual toluene and styrene in stripper 
crumb of the of the following types of rubber: polybutadiene (PBR) and 
styrene/butadiene rubber (SBR), both derived from solution 
polymerization processes that utilize toluene as the polymerization 
solvent.
    1.2 The method is applicable to a wide range of concentrations of 
toluene and styrene provided that calibration standards cover the 
desired range. It is applicable at least over the range of 0.01 to 10.0 
% residual toluene and from 0.1 to 3.0 % residual styrene. It is 
probably applicable over a wider range, but this must be verified prior 
to use.
    1.3 The method may also be applicable to other process samples as 
long as they are of a similar composition to stripper crumb. See section 
3.1 of this method for a description of stripper crumb.

                          2.0 Summary of Method

    2.1 The wet crumb is placed in a sealed vial and run on a headspace 
sampler which heats the vial to a specified temperature for a specific 
time and then injects a known volume of vapor into a capillary GC. The 
concentration of each component in the vapor is proportional to the 
level of that component in the crumb sample and does not depend on water 
content of the crumb.
    2.2 Identification of each component is performed by comparing the 
retention times to those of known standards.
    2.3 Results are calculated by the external standard method since 
injections are all performed in an identical manner. The response for 
each component is compared with that obtained from dosed samples of 
crumb.
    2.4 Measured results of each compound are corrected by dividing each 
by the average recovery efficiency determined for the same compound in 
the same sample type.

                             3.0 Definitions

    3.1 Stripper crumb refers to pieces of rubber resulting from the 
steam stripping of a toluene solution of the same polymer in a water 
slurry. The primary component of this will be polymer with lesser 
amounts of entrained water and residual toluene and other hydrocarbons. 
The amounts of hydrocarbons present must be such that the crumb is a 
solid material, generally less that 10 % of the dry rubber weight.

                            4.0 Interferences

    4.1 Contamination is not normally a problem since samples are sealed 
into vials immediately on sampling.
    4.2 Cross contamination in the headspace sampler should not be a 
problem if the correct sampler settings are used. This should be 
verified by running a blank sample immediately following a normal or 
high sample. Settings may be modified if necessary if this proves to be 
a problem, or a blank sample may be inserted between samples.
    4.3 Interferences may occur if volatile hydrocarbons are present 
which have retention times close to that of the components of interest. 
Since the solvent makeup of the processes involved are normally fairly 
well defined this should not be a problem. If it is found to be the 
case, switching to a different chromatographic column will probably 
resolve the situation.

                               5.0 Safety

    5.1 The chemicals specified in this method should all be handled 
according to standard laboratory practices as well as any special 
precautions that may be listed in the MSDS for that compound.
    5.2 Sampling of strippers or other process streams may involve high 
pressures and temperatures or may have the potential for exposure to 
chemical fumes. Only personnel who have been trained in the specific 
sampling procedures required for that process should perform this 
operation. An understanding of the process involved is necessary. Proper 
personal protective equipment should be worn. Any sampling devices 
should be inspected prior to use. A detailed sampling procedure which 
specifies exactly how to obtain the sample must be written and followed.

                       7.0 Reagents and Standards

    7.1 Toluene, 99.9+% purity, HPLC grade.
    7.2 Styrene, 99.9+% purity, HPLC grade.
    7.3 Dry rubber of same type as the stripper crumb samples.

             8.0 Sample Collection, Preservation and Storage

    8.1 Collect a sample of crumb in a manner appropriate for the 
process equipment being sampled.
    8.1.1 If conditions permit, this may be done by passing a stream of 
the crumb slurry through a strainer, thus separating the crumb from the 
water. Allow the water to drain freely, do not attempt to squeeze any 
water from the crumb. Results will not depend on the exact water content 
of the samples. Immediately place several pieces of crumb directly into 
a headspace vial. This should be done with rubber gloves to protect the 
hands from both the heat and from contact with residual hydrocarbons. 
The vial should be between \1/4\ and \1/3\ full. Results do not depend 
on sample size as long as there is sufficient sample to reach an 
equilibrium vapor pressure in the headspace of the vial. Cap and seal 
the vial. Prepare each sample at least in duplicate. This is to minimize 
the effect of the variation that naturally occurs in the composition of 
non homogeneous crumb. The free water is not analyzed by this method and 
should be disposed of appropriately along with any unused rubber crumb.
    8.1.2 Alternatively the process can be sampled in a specially 
constructed sealed bomb which can then be transported to the laboratory. 
The bomb is then cooled to ambient temperature by applying a stream of 
running water. The bomb can then be opened and the crumb separated from 
the water and the vials filled as described in section 8.1.1 of this 
method. The bomb may be stored up to 8 hours prior to transferring the 
crumb into vials.
    8.2 The sealed headspace vials may be run immediately or may be 
stored up to 72 hours prior to running. It is possible that even longer 
storage times may be acceptable, but this must be verified for the 
particular type of sample being analyzed (see section 9.2.3 of this 
method). The main concern here is that some types of rubber eventually 
may flow, thus compacting the crumb so that the surface area is reduced. 
This may have some effect on the headspace equilibration.

                           9.0 Quality Control

    9.1 The laboratory is required to operate a formal quality control 
program. This consists of an initial demonstration of the capability of 
the method as well as ongoing analysis of standards, blanks and spiked 
samples to demonstrate continued performance.
    9.1.1 When the method is first set up a calibration is run 
(described in section 10 of this method) and an initial demonstration of 
method capability is performed (described in section 9.2 of this 
method). Also recovery efficiency for each type of sample must be 
determined (see section 9.4 of this method).
    9.1.2 It is permissible to modify this method in order to improve 
separations or make other improvements, provided that all performance 
specifications are met. Each time a modification to the method is made 
it is necessary to repeat the calibration (section 10 of this method), 
the demonstration of method performance (section 9.2 of this method) and 
the recovery efficiency for each type of sample (section 9.4 of this 
method).
    9.1.3 Ongoing performance should be monitored by running a spiked 
rubber standard. If this test fails to demonstrate that the analysis is 
in control, then corrective action must be taken. This method is 
described in section 9.3 of this method.
    9.1.4 If new types of samples are being analyzed then recovery 
efficiency for each new type of sample must be determined. New type 
includes any change, such as polymer type, physical form or a 
significant change in the composition of the matrix.
    9.2 Initial demonstration of method capability to establish the 
accuracy and precision

[[Page 1053]]

of the method. This is to be run following the calibration described in 
section 10 of this method.
    9.2.1 Prepare a series of identical spiked rubber standards as 
described in section 9.3 of this method. A sufficient number to 
determine statistical information on the test should be run. Ten may be 
a suitable number, depending on the quality control methodology used at 
the laboratory running the tests. These are run in the same manner as 
unknown samples (see section 11 of this method).
    9.2.2 Determine mean and standard deviation for the results. Use 
these to determine the capability of the method and to calculate 
suitable control limits for the ongoing performance check which will 
utilize the same standards.
    9.2.3 Prepare several additional spiked rubber standards and run 2 
each day to determine the suitability of storage of the samples for 24, 
48 and 72 hours or longer if longer storage times are desired.
    9.3 A spiked rubber standard should be run on a regular basis to 
verify system performance. This would probably be done daily if samples 
are run daily. This is prepared in the same manner as the calibration 
standards (section 10.1 of this method), except that only one 
concentration of toluene and styrene is prepared. Choose concentrations 
of toluene and styrene that fall in the middle of the range expected in 
the stripper crumb and then do not change these unless there is a major 
change in the composition of the unknowns. If it becomes necessary to 
change the composition of this standard the initial performance 
demonstration must be repeated with the new standard (section 9.2 of 
this method).
    9.3.1 Each day prepare one spiked rubber standard to be run the 
following day. The dry rubber may be prepared in bulk and stored for any 
length of time consistent with the shelf life of the product. The 
addition of water and hydrocarbons must be performed daily and all the 
steps described under section 10.1 of this method must be followed.
    9.3.2 Run the spiked rubber standard prepared the previous day. 
Record the results and plot on an appropriate control chart or other 
means of determining statistical control.
    9.3.3 If the results for the standard indicate that the test is out 
of control then corrective action must be taken. This may include a 
check on procedures, instrument settings, maintenance or recalibration. 
Samples may be stored (see section 8.2 of this method) until compliance 
is demonstrated.
    9.4 Recovery efficiency must be determined once for each sample type 
and whenever modifications are made to the method.
    9.4.1 For each sample type collect 12 samples from the process 
(section 8.1 of this method). This should be done when the process is 
operating in a normal manner and residual hydrocarbon levels are in the 
normal range. Half the vials and caps should be tared, labeled 
``spiked'' and numbered 1 through 6. The other vials are labeled 
``unspiked'' and need not be tared but are also numbered 1 through 6. 
Immediately on sampling, the vials should be capped to prevent loss of 
volatiles. Allow all the samples to cool completely to ambient 
temperature. Reweigh each of the vials labeled ``spiked'' to determine 
the weight of wet crumb inside.
    9.4.2 The dry weight of rubber present in the wet crumb is estimated 
by multiplying the weight of wet crumb by the fraction of nonvolatiles 
typical for the sample. If this is not known, an additional quantity of 
crumb may be sampled, weighed, dried in an oven and reweighed to 
determine the fraction of volatiles and nonvolatiles prior to starting 
this procedure.
    9.4.3 To the vials labeled ``spiked'' add an amount of a mixture of 
toluene and styrene that is between 40 and 60 % of the amount expected 
in the crumb. This is done by removing the cap, adding the mixture by 
syringe, touching the tip of the needle to the sample in order to remove 
the drop and then immediately recapping the vials. The mixture is not 
added through the septum, because a punctured septum may leak and vent 
vapors as the vial is heated. The weights of toluene and styrene added 
may be calculated from the volumes of the mixture added, its composition 
and density, or may be determined by the weight of the vials and caps 
prior to and after addition. The exact dry weight of rubber present and 
the concentration of residual toluene and styrene are not known at this 
time so an exact calculation of the concentration of hydrocarbons is not 
possible until the test is completed.
    9.4.4 Place all the vials onto a shaker or tumbler for 24 [plusmn] 2 
hours. This is essential in order for the hydrocarbons to be evenly 
distributed and completely absorbed into the rubber. If this is not 
followed the toluene and styrene will be mostly at the surface of the 
rubber and high results will be obtained.
    9.4.5 Remove the vials from the shaker and tap them so that all the 
crumb settles to the bottom of the vials. Allow them to stand for 1 hour 
prior to analysis to allow any liquid to drain fully to the bottom.
    9.4.6 Run the spiked and unspiked samples in the normal manner. 
Record the concentrations of toluene and styrene reported for each pair 
of spiked and unspiked samples with the same vial number.
    9.4.7 Open each of the vials labeled ``spiked'', remove all the 
rubber crumb and place it into a tarred drying pan. Place in a 100 deg C 
oven for two hours, cool and reweigh. Subtract the weight of the tare to 
give the dry weight of rubber in each spiked vial. Calculate the 
concentration of toluene and styrene spiked into each vial as percent

[[Page 1054]]

of dry rubber weight. This will be slightly different for each vial 
since the weights of dry rubber will be different.
    9.4.8 For each hydrocarbon calculate the average recovery efficiency 
(R) using the following equations:

    R=R--[Sigma](Pn)/6 (average of the 6 individual 
Rn values)

    Where:
    Rn=(Cns--Cnu) / Sn

    Where:
    n=vial number
    Cns=concentration of compound measured in spiked sample number n.
    Cnu=concentration of compound measured in unspiked sample number n.
    Sn=theoretical concentration of compound spiked into sample n 
calculated in step 9.4.7

    9.4.9 A different R value should be obtained for each compound 
(styrene and toluene) and for each sample type.
    9.4.10 A value of R between 0.70 and 1.30 is acceptable.
    9.4.11 R is used to correct all reported results for each compound 
by dividing the measured results of each compound by the R for that 
compound for the same sample type (see section 12.2 of this method.)

                            10.0 Calibration

    10.1 Calibration standards are prepared by dosing known amounts of 
the hydrocarbons of interest into vials containing known amounts of 
rubber and water.
    10.1.1 Cut a sufficient quantity of dry rubber of the same type as 
will be analyzed into pieces about the same size as that of the crumb. 
Place these in a single layer on a piece of aluminum foil or other 
suitable surface and place into a forced air oven at 100 [deg]C for four 
hours. This is to remove any residual hydrocarbons that may be present. 
This step may be performed in advance.
    10.1.2 Into each of a series of vials add 3.0 g of the dry rubber.
    10.1.3 Into each vial add 1.0 ml distilled water or an amount that 
is close to the amount that will be present in the unknowns. The exact 
amount of water present does not have much effect on the analysis, but 
it is necessary to have a saturated environment. The water will also aid 
in the uniform distribution of the spiked hydrocarbons over the surface 
of the rubber after the vials are placed on the shaker (in step 10.1.5 
of this method).
    10.1.4 Into each vial add varying amounts of toluene and styrene by 
microliter syringe and cap the vials immediately to prevent loss. The 
tip of the needle should be carefully touched to the rubber in order to 
transfer the last drop to the rubber. Toluene and styrene may first be 
mixed together in suitable proportions and added together if desired. 
The weights of toluene and styrene added may be calculated from the 
volumes of the mixture added, its composition and density, or may be 
determined by the weight of the vials and caps prior to and after 
addition. Concentrations of added hydrocarbons are calculated as percent 
of the dry rubber weight. At least 5 standards should be prepared with 
the amounts of hydrocarbons added being calculated to cover the entire 
range possible in the unknowns. Retain two samples with no added 
hydrocarbons as blanks.
    10.1.5 Place all the vials onto a shaker or tumbler for 24 [plusmn] 
2 hours. This is essential in order for the hydrocarbons to be evenly 
distributed and completely absorbed into the rubber. If this is not 
followed the toluene and styrene will be mostly at the surface of the 
rubber and high results will be obtained.
    10.1.6 Remove the vials from the shaker and tap them so that all the 
crumb settles to the bottom of the vials. Allow them to stand for 1 hour 
prior to analysis to allow any liquid to drain fully to the bottom.
    10.2 Run the standards and blanks in the same manner as described 
for unknowns (section 11 of this method), starting with a blank, then in 
order of increasing hydrocarbon content and ending with the other blank.
    10.3 Verify that the blanks are sufficiently free from toluene and 
styrene or any interfering hydrocarbons.
    10.3.1 It is possible that trace levels may be present even in dry 
product. If levels are high enough that they will interfere with the 
calibration then the drying procedure in section 10.1.1 of this method 
should be reviewed and modified as needed to ensure that suitable 
standards can be prepared.
    10.3.2 It is possible that the final blank is contaminated by the 
previous standard. If this is the case review and modify the sampler 
parameters as needed to eliminate this problem. If necessary it is 
possible to run blank samples between regular samples in order to reduce 
this problem, though it should not be necessary if the sampler is 
properly set up.
    10.4 Enter the amounts of toluene and styrene added to each of the 
samples (as calculated in section 10.1.4 of this method) into the 
calibration table and perform a calibration utilizing the external 
standard method of analysis.
    10.5 At low concentrations the calibration should be close to 
linear. If a wide range of levels are to be determined it may be 
desirable to apply a nonlinear calibration to get the best fit.

                             11.0 Procedure

    11.1 Place the vials in the tray of the headspace sampler. Enter the 
starting and ending positions through the console of the sampler. For 
unknown samples each is run in

[[Page 1055]]

duplicate to minimize the effect of variations in crumb composition. If 
excessive variation is noted it may be desirable to run more than two of 
each sample.
    11.2 Make sure the correct method is loaded on the Chemstation. Turn 
on the gas flows and light the FID flame.
    11.3 Start the sequence on the Chemstation. Press the START button 
on the headspace unit. The samples will be automatically injected after 
equilibrating for 30 minutes in the oven. As each sample is completed 
the Chemstation will calculate and print out the results as percent 
toluene and styrene in the crumb based on the dry weight of rubber.

                   12.0 Data Analysis and Calculations

    12.1 For each set of duplicate samples calculate the average of the 
measured concentration of toluene and styrene. If more than two 
replicates of each sample are run calculate the average over all 
replicates.
    12.2 For each sample correct the measured amounts of toluene and 
styrene using the following equation:

    Corrected Result = Cm/R

    Where:
    Cm = Average measured concentration for that compound.
    R = Recovery efficiency for that compound in the same sample type 
(see section 9.4 of this method)

    12.3 Report the recovery efficiency (R) and the corrected results of 
toluene and styrene for each sample.

                         13.0 Method Performance

    13.1 This method can be very sensitive and reproducible. The actual 
performance depends largely on the exact nature of the samples being 
analyzed. Actual performance must be determined by each laboratory for 
each sample type.
    13.2 The main source of variation is the actual variation in the 
composition of non homogeneous crumb in a stripping system and the small 
sample sizes employed here. It therefore is the responsibility of each 
laboratory to determine the optimum number of replicates of each sample 
required to obtain accurate results.

                        14.0 Pollution Prevention

    14.1 Samples should be kept sealed when possible in order to prevent 
evaporation of hydrocarbons.
    14.2 When drying of samples is required it should be done in an oven 
which vents into a suitable device that can trap the hydrocarbons 
released.
    14.3 Dispose of samples as described in section 15.

                          15.0 Waste Management

    15.1 Excess stripper crumb and water as well as the contents of the 
used sample vials should be properly disposed of in accordance with 
local and federal regulations.
    15.2 Preferably this will be accomplished by having a system of 
returning unused and spent samples to the process.

   Method 313B--The Determination of Residual Hydrocarbon in Solution 
                Polymers by Capillary Gas Chromatography

                                1.0 Scope

    1.1 This method is applicable to solution polymerized polybutadiene 
(PBD).
    1.2 This method quantitatively determines n-hexane in wet crumb 
polymer at levels from 0.08 to 0.15% by weight.
    1.3 This method may be extended to the determination of other 
hydrocarbons in solution produced polymers with proper experimentation 
and documentation.

                         2.0 Principle of Method

    2.1 A weighed sample of polymer is dissolved in chloroform and the 
cement is coagulated with an isopropyl alcohol solution containing a 
specific amount of alpha-methyl styrene (AMS) as the internal standard. 
The extract of this coagulation is then injected into a gas

             8.0 Sample Collection, Preservation and Storage

    8.1 A sampling device similar to Figure 1 is used to collect a non-
vented crumb rubber sample at a location that is after the stripping 
operation but before the sample is exposed to the atmosphere.
    8.2 The crumb rubber is allowed to cool before opening the sampling 
device and removing the sample.
    8.3 The sampling device is opened and the crumb rubber sample is 
collected in the sampling basket.
    8.4 One pound of crumb rubber sample is placed into a polyethylene 
bag. The bag is labeled with the time, date and sample location.
    8.5 The sample should be delivered to the laboratory for testing 
within one hour of sampling.
    8.6 Laboratory testing will be done within 3 hours of the sampling 
time.
    8.7 No special storage conditions are required unless the storage 
time exceeds 3 hours in which case refrigeration of the samples is 
recommended.

                           9.0 Quality Control

    9.1 For each sample type, 12 samples shall be obtained from the 
process for the recovery study. Half of the vials and caps shall be 
tared, labeled ``spiked'', and numbered 1 through 6. The other vials 
shall be labeled ``unspiked'' and need not be tared, but are also 
numbered 1 through 6.
    9.2 Determine the % moisture content of the crumb sample. After 
determining the % moisture content, the correction factor for 
calculating the dry crumb weight can be determined by using the equation 
in section 12.2 of this method.
    9.3 Run the spiked and unspiked samples in the normal manner. Record 
the concentrations of the n-hexane content of the mixed hexane reported 
for each pair of spiked and unspiked samples.

[[Page 1057]]

    9.4 For the recovery study, each sample of crumb shall be dissolved 
in chloroform containing a known amount of mixed hexane solvent.
    9.5 For each hydrocarbon, calculate the recovery efficiency (R) 
using the following equations:

    Mr=Ms-Mu
    R=Mr/S

    Where:
    Mu=Measured amount of compound in the unspiked sample
    Ms=Measured amount of compound in the spiked sample
    Mr=Measured amount of the spiked compound
    S=Amount of compound added to the spiked sample
    R=Fraction of spiked compound recovered

    9.6 Normally a value of R between 0.70 and 1.30 is acceptable.
    9.7 R is used to correct all reported results for each compound by 
dividing the measured results of each compound by the R for that 
compound for the same sample type.

    Method 315--Determination of Particulate and Methylene Chloride 
  Extractable Matter (MCEM) From Selected Sources at Primary Aluminum 
                          Production Facilities

    Note: This method does not include all of the specifications (e.g., 
equipment and supplies) and procedures (e.g., sampling and analytical) 
essential to its performance. Some material is incorporated by reference 
from other methods in this part. Therefore, to obtain reliable results, 
persons using this method should have a thorough knowledge of at least 
the following additional test methods: Method 1, Method 2, Method 3, and 
Method 5 of 40 CFR part 60, appendix A.

                       1.0 Scope and Application.

    1.1 Analytes. Particulate matter (PM). No CAS number assigned. 
Methylene chloride extractable matter (MCEM). No CAS number assigned.
    1.2 Applicability. This method is applicable for the simultaneous 
determination of PM and MCEM when specified in an applicable regulation. 
This method was developed by consensus with the Aluminum Association and 
the U.S. Environmental Protection Agency (EPA) and has limited precision 
estimates for MCEM; it should have similar precision to Method 5 for PM 
in 40 CFR part 60, appendix A since the procedures are similar for PM.
    1.3 Data quality objectives. Adherence to the requirements of this 
method will enhance the quality of the data obtained from air pollutant 
sampling methods.

                         2.0 Summary of Method.

    Particulate matter and MCEM are withdrawn isokinetically from the 
source. PM is collected on a glass fiber filter maintained at a 
temperature in the range of l20 [plusmn] 14 [deg]C (248 [plusmn]25 
[deg]F) or such other temperature as specified by an applicable subpart 
of the standards or approved by the Administrator for a particular 
application. The PM mass, which includes any material that condenses on 
the probe and is subsequently removed in an acetone rinse or on the 
filter at or above the filtration temperature, is determined 
gravimetrically after removal of uncombined water. MCEM is then 
determined by adding a methylene chloride rinse of the probe and filter 
holder, extracting the condensable hydrocarbons collected in the 
impinger water, adding an acetone rinse followed by a methylene chloride 
rinse of the sampling train components after the filter and before the 
silica gel impinger, and determining residue gravimetrically after 
evaporating the solvents.

    Note: Mention of trade names or specific products does not 
constitute endorsement by the EPA.

    6.1 Sample collection. The following items are required for sample 
collection:
    6.1.1 Sampling train. A schematic of the sampling train used in this 
method is shown in Figure 5-1, Method 5, 40 CFR part 60, appendix A. 
Complete construction details are given in APTD-0581 (Reference 2 in 
section 17.0 of this method); commercial models of this train are also 
available. For changes from APTD-0581 and for allowable modifications of 
the train shown in Figure 5-1, Method 5, 40 CFR part 60, appendix A, see 
the following subsections.

    Note: The operating and maintenance procedures for the sampling 
train are described in APTD-0576 (Reference 3 in section 17.0 of this 
method). Since correct usage is important in obtaining valid results, 
all users should read APTD-0576 and adopt the operating and maintenance 
procedures outlined

[[Page 1059]]

in it, unless otherwise specified herein. The use of grease for sealing 
sampling train components is not recommended because many greases are 
soluble in methylene chloride. The sampling train consists of the 
following components:

    6.1.1.1 Probe nozzle. Glass or glass lined with sharp, tapered 
leading edge. The angle of taper shall be [le]30 [deg], and the taper 
shall be on the outside to preserve a constant internal diameter. The 
probe nozzle shall be of the button-hook or elbow design, unless 
otherwise specified by the Administrator. Other materials of 
construction may be used, subject to the approval of the Administrator. 
A range of nozzle sizes suitable for isokinetic sampling should be 
available. Typical nozzle sizes range from 0.32 to 1.27 cm (\1/8\ to \1/
2\ in.) inside diameter (ID) in increments of 0.16 cm (\1/16\ in.). 
Larger nozzle sizes are also available if higher volume sampling trains 
are used. Each nozzle shall be calibrated according to the procedures 
outlined in section 10.0 of this method.
    6.1.1.2 Probe liner. Borosilicate or quartz glass tubing with a 
heating system capable of maintaining a probe gas temperature at the 
exit end during sampling of 120[plusmn]14 [deg]C (248[plusmn]25 [deg]F), 
or such other temperature as specified by an applicable subpart of the 
standards or approved by the Administrator for a particular application. 
Because the actual temperature at the outlet of the probe is not usually 
monitored during sampling, probes constructed according to APTD-0581 and 
using the calibration curves of APTD-0576 (or calibrated according to 
the procedure outlined in APTD-0576) will be considered acceptable. 
Either borosilicate or quartz glass probe liners may be used for stack 
temperatures up to about 480 [deg]C (900 [deg]F); quartz liners shall be 
used for temperatures between 480 and 900 [deg]C (900 and 1,650 [deg]F). 
Both types of liners may be used at higher temperatures than specified 
for short periods of time, subject to the approval of the Administrator. 
The softening temperature for borosilicate glass is 820 [deg]C (1,500 
[deg]F) and for quartz glass it is 1,500 [deg]C (2,700 [deg]F).
    6.1.1.3 Pitot tube. Type S, as described in section 6.1 of Method 2, 
40 CFR part 60, appendix A, or other device approved by the 
Administrator. The pitot tube shall be attached to the probe (as shown 
in Figure 5-1 of Method 5, 40 CFR part 60, appendix A) to allow constant 
monitoring of the stack gas velocity. The impact (high pressure) opening 
plane of the pitot tube shall be even with or above the nozzle entry 
plane (see Method 2, Figure 2-6b, 40 CFR part 60, appendix A) during 
sampling. The Type S pitot tube assembly shall have a known coefficient, 
determined as outlined in section 10.0 of Method 2, 40 CFR part 60, 
appendix A.
    6.1.1.4 Differential pressure gauge. Inclined manometer or 
equivalent device (two), as described in section 6.2 of Method 2, 40 CFR 
part 60, appendix A. One manometer shall be used for velocity head (Dp) 
readings, and the other, for orifice differential pressure readings.
    6.1.1.5 Filter holder. Borosilicate glass, with a glass frit filter 
support and a silicone rubber gasket. The holder design shall provide a 
positive seal against leakage from the outside or around the filter. The 
holder shall be attached immediately at the outlet of the probe (or 
cyclone, if used).
    6.1.1.6 Filter heating system. Any heating system capable of 
maintaining a temperature around the filter holder of 120[plusmn]14 
[deg]C (248[plusmn]25 [deg]F) during sampling, or such other temperature 
as specified by an applicable subpart of the standards or approved by 
the Administrator for a particular application. Alternatively, the 
tester may opt to operate the equipment at a temperature lower than that 
specified. A temperature gauge capable of measuring temperature to 
within 3 [deg]C (5.4 [deg]F) shall be installed so that the temperature 
around the filter holder can be regulated and monitored during sampling. 
Heating systems other than the one shown in APTD-0581 may be used.
    6.1.1.7 Temperature sensor. A temperature sensor capable of 
measuring temperature to within [plusmn]3 [deg]C (5.4 [deg]F) shall be 
installed so that the sensing tip of the temperature sensor is in direct 
contact with the sample gas, and the temperature around the filter 
holder can be regulated and monitored during sampling.
    6.1.1.8 Condenser. The following system shall be used to determine 
the stack gas moisture content: four glass impingers connected in series 
with leak-free ground glass fittings. The first, third, and fourth 
impingers shall be of the Greenburg-Smith design, modified by replacing 
the tip with a 1.3 cm (1/2 in.) ID glass tube extending to about 1.3 cm 
(1/2 in.) from the bottom of the flask. The second impinger shall be of 
the Greenburg-Smith design with the standard tip. The first and second 
impingers shall contain known quantities of water (section 8.3.1 of this 
method), the third shall be empty, and the fourth shall contain a known 
weight of silica gel or equivalent desiccant. A temperature sensor 
capable of measuring temperature to within 1 [deg]C (2 [deg]F) shall be 
placed at the outlet of the fourth impinger for monitoring.
    6.1.1.9 Metering system. Vacuum gauge, leak-free pump, temperature 
sensors capable of measuring temperature to within 3 [deg]C (5.4 
[deg]F), dry gas meter (DGM) capable of measuring volume to within 2 
percent, and related equipment, as shown in Figure 5-1 of Method 5, 40 
CFR part 60, appendix A. Other metering systems capable of maintaining 
sampling rates within 10 percent of isokinetic and of determining sample 
volumes to within 2 percent may be used, subject to the approval of the 
Administrator.

[[Page 1060]]

When the metering system is used in conjunction with a pitot tube, the 
system shall allow periodic checks of isokinetic rates.
    6.1.1.10 Sampling trains using metering systems designed for higher 
flow rates than that described in APTD-0581 or APTD-0576 may be used 
provided that the specifications of this method are met.
    6.1.2 Barometer. Mercury, aneroid, or other barometer capable of 
measuring atmospheric pressure to within 2.5 mm (0.1 in.) Hg.

    Note: The barometric reading may be obtained from a nearby National 
Weather Service station. In this case, the station value (which is the 
absolute barometric pressure) shall be requested and an adjustment for 
elevation differences between the weather station and sampling point 
shall be made at a rate of minus 2.5 mm (0.1 in) Hg per 30 m (100 ft) 
elevation increase or plus 2.5 mm (0.1 in) Hg per 30 m (100 ft) 
elevation decrease.

    6.1.3 Gas density determination equipment. Temperature sensor and 
pressure gauge, as described in sections 6.3 and 6.4 of Method 2, 40 CFR 
part 60, appendix A, and gas analyzer, if necessary, as described in 
Method 3, 40 CFR part 60, appendix A. The temperature sensor shall, 
preferably, be permanently attached to the pitot tube or sampling probe 
in a fixed configuration, such that the tip of the sensor extends beyond 
the leading edge of the probe sheath and does not touch any metal. 
Alternatively, the sensor may be attached just prior to use in the 
field. Note, however, that if the temperature sensor is attached in the 
field, the sensor must be placed in an interference-free arrangement 
with respect to the Type S pitot tube openings (see Method 2, Figure 2-
4, 40 CFR part 60, appendix A). As a second alternative, if a difference 
of not more than 1 percent in the average velocity measurement is to be 
introduced, the temperature sensor need not be attached to the probe or 
pitot tube. (This alternative is subject to the approval of the 
Administrator.)
    6.2 Sample recovery. The following items are required for sample 
recovery:
    6.2.1 Probe-liner and probe-nozzle brushes. Nylon or 
Teflon[reg] bristle brushes with stainless steel wire 
handles. The probe brush shall have extensions (at least as long as the 
probe) constructed of stainless steel, nylon, Teflon[reg], or 
similarly inert material. The brushes shall be properly sized and shaped 
to brush out the probe liner and nozzle.
    6.2.2 Wash bottles. Glass wash bottles are recommended. Polyethylene 
or tetrafluoroethylene (TFE) wash bottles may be used, but they may 
introduce a positive bias due to contamination from the bottle. It is 
recommended that acetone not be stored in polyethylene or TFE bottles 
for longer than a month.
    6.2.3 Glass sample storage containers. Chemically resistant, 
borosilicate glass bottles, for acetone and methylene chloride washes 
and impinger water, 500 ml or 1,000 ml. Screw-cap liners shall either be 
rubber-backed Teflon[reg] or shall be constructed so as to be 
leak-free and resistant to chemical attack by acetone or methylene 
chloride. (Narrow-mouth glass bottles have been found to be less prone 
to leakage.) Alternatively, polyethylene bottles may be used.
    6.2.4 Petri dishes. For filter samples, glass, unless otherwise 
specified by the Administrator.
    6.2.5 Graduated cylinder and/or balance. To measure condensed water, 
acetone wash and methylene chloride wash used during field recovery of 
the samples, to within 1 ml or 1 g. Graduated cylinders shall have 
subdivisions no greater than 2 ml. Most laboratory balances are capable 
of weighing to the nearest 0.5 g or less. Any such balance is suitable 
for use here and in section 6.3.4 of this method.
    6.2.6 Plastic storage containers. Air-tight containers to store 
silica gel.
    6.2.7 Funnel and rubber policeman. To aid in transfer of silica gel 
to container; not necessary if silica gel is weighed in the field.
    6.2.8 Funnel. Glass or polyethylene, to aid in sample recovery.
    6.3 Sample analysis. The following equipment is required for sample 
analysis:
    6.3.1 Glass or Teflon[reg] weighing dishes.
    6.3.2 Desiccator. It is recommended that fresh desiccant be used to 
minimize the chance for positive bias due to absorption of organic 
material during drying.
    6.3.3 Analytical balance. To measure to within 0.l mg.
    6.3.4 Balance. To measure to within 0.5 g.
    6.3.5 Beakers. 250 ml.
    6.3.6 Hygrometer. To measure the relative humidity of the laboratory 
environment.
    6.3.7 Temperature sensor. To measure the temperature of the 
laboratory environment.
    6.3.8 Buchner fritted funnel. 30 ml size, fine (<50 micron)-porosity 
fritted glass.
    6.3.9 Pressure filtration apparatus.
    6.3.10 Aluminum dish. Flat bottom, smooth sides, and flanged top, 18 
mm deep and with an inside diameter of approximately 60 mm.

                       7.0 Reagents and Standards.

    7.l Sample collection. The following reagents are required for 
sample collection:
    7.1.1 Filters. Glass fiber filters, without organic binder, 
exhibiting at least 99.95 percent efficiency (<0.05 percent penetration) 
on 0.3 micron dioctyl phthalate smoke particles. The filter efficiency 
test shall be conducted in accordance with ASTM Method D 2986-95A 
(incorporated by reference in Sec. 63.841 of this part). Test data from 
the supplier's quality control program are sufficient for this purpose. 
In sources containing S02 or

[[Page 1061]]

S03, the filter material must be of a type that is unreactive 
to S02 or S03. Reference 10 in section 17.0 of 
this method may be used to select the appropriate filter.
    7.1.2 Silica gel. Indicating type, 6 to l6 mesh. If previously used, 
dry at l75 [deg]C (350 [deg]F) for 2 hours. New silica gel may be used 
as received. Alternatively, other types of desiccants (equivalent or 
better) may be used, subject to the approval of the Administrator.
    7.1.3 Water. When analysis of the material caught in the impingers 
is required, deionized distilled water shall be used. Run blanks prior 
to field use to eliminate a high blank on test samples.
    7.1.4 Crushed ice.
    7.1.5 Stopcock grease. Acetone-insoluble, heat-stable silicone 
grease. This is not necessary if screw-on connectors with Teflon'' 
sleeves, or similar, are used. Alternatively, other types of stopcock 
grease may be used, subject to the approval of the Administrator. 
[Caution: Many stopcock greases are methylene chloride-soluble. Use 
sparingly and carefully remove prior to recovery to prevent 
contamination of the MCEM analysis.]
    7.2 Sample recovery. The following reagents are required for sample 
recovery:
    7.2.1 Acetone. Acetone with blank values < 1 ppm, by weight residue, 
is required. Acetone blanks may be run prior to field use, and only 
acetone with low blank values may be used. In no case shall a blank 
value of greater than 1E-06 of the weight of acetone used be subtracted 
from the sample weight.

    Note: This is more restrictive than Method 5, 40 CFR part 60, 
appendix A. At least one vendor (Supelco Incorporated located in 
Bellefonte, Pennsylvania) lists <1 mg/l as residue for its Environmental 
Analysis Solvents.

    7.2.2 Methylene chloride. Methylene chloride with a blank value <1.5 
ppm, by weight, residue. Methylene chloride blanks may be run prior to 
field use, and only methylene chloride with low blank values may be 
used. In no case shall a blank value of greater than 1.6E-06 of the 
weight of methylene chloride used be subtracted from the sample weight.

    Note: A least one vendor quotes <1 mg/l for Environmental Analysis 
Solvents-grade methylene chloride.

    7.3 Sample analysis. The following reagents are required for sample 
analysis:
    7.3.l Acetone. Same as in section 7.2.1 of this method.
    7.3.2 Desiccant. Anhydrous calcium sulfate, indicating type. 
Alternatively, other types of desiccants may be used, subject to the 
approval of the Administrator.
    7.3.3 Methylene chloride. Same as in section 7.2.2 of this method.

      8.0 Sample Collection, Preservation, Storage, and Transport.

    Note: The complexity of this method is such that, in order to obtain 
reliable results, testers should be trained and experienced with the 
test procedures.

    8.11 Pretest preparation. It is suggested that sampling equipment be 
maintained according to the procedures described in APTD-0576.
    8.1.1 Weigh several 200 g to 300 g portions of silica gel in 
airtight containers to the nearest 0.5 g. Record on each container the 
total weight of the silica gel plus container. As an alternative, the 
silica gel need not be preweighed but may be weighed directly in its 
impinger or sampling holder just prior to train assembly.
    8.1.2 A batch of glass fiber filters, no more than 50 at a time, 
should placed in a soxhlet extraction apparatus and extracted using 
methylene chloride for at least 16 hours. After extraction, check 
filters visually against light for irregularities, flaws, or pinhole 
leaks. Label the shipping containers (glass or plastic petri dishes), 
and keep the filters in these containers at all times except during 
sampling and weighing.
    8.1.3 Desiccate the filters at 20 [plusmn]5.6 [deg]C (68 [plusmn]10 
[deg]F) and ambient pressure for at least 24 hours and weigh at 
intervals of at least 6 hours to a constant weight, i.e., <0.5 mg change 
from previous weighing; record results to the nearest 0.1 mg. During 
each weighing the filter must not be exposed to the laboratory 
atmosphere for longer than 2 minutes and a relative humidity above 50 
percent. Alternatively (unless otherwise specified by the 
Administrator), the filters may be oven-dried at 104 [deg]C (220 [deg]F) 
for 2 to 3 hours, desiccated for 2 hours, and weighed. Procedures other 
than those described, which account for relative humidity effects, may 
be used, subject to the approval of the Administrator.
    8.2 Preliminary determinations.
    8.2.1 Select the sampling site and the minimum number of sampling 
points according to Method 1, 40 CFR part 60, appendix A or as specified 
by the Administrator. Determine the stack pressure, temperature, and the 
range of velocity heads using Method 2, 40 CFR part 60, appendix A; it 
is recommended that a leak check of the pitot lines (see section 8.1 of 
Method 2, 40 CFR part 60, appendix A) be performed. Determine the 
moisture content using Approximation Method 4 (section 1.2 of Method 4, 
40 CFR part 60, appendix A) or its alternatives to make isokinetic 
sampling rate settings. Determine the stack gas dry molecular weight, as 
described in section 8.6 of Method 2, 40 CFR part 60, appendix A; if 
integrated Method 3 sampling is used for molecular weight determination, 
the integrated bag sample shall be taken simultaneously with, and for

[[Page 1062]]

the same total length of time as, the particulate sample run.
    8.2.2 Select a nozzle size based on the range of velocity heads such 
that it is not necessary to change the nozzle size in order to maintain 
isokinetic sampling rates. During the run, do not change the nozzle 
size. Ensure that the proper differential pressure gauge is chosen for 
the range of velocity heads encountered (see section 8.2 of Method 2, 40 
CFR part 60, appendix A).
    8.2.3 Select a suitable probe liner and probe length such that all 
traverse points can be sampled. For large stacks, consider sampling from 
opposite sides of the stack to reduce the required probe length.
    8.2.4 Select a total sampling time greater than or equal to the 
minimum total sampling time specified in the test procedures for the 
specific industry such that: (1) The sampling time per point is not less 
than 2 minutes (or some greater time interval as specified by the 
Administrator); and (2) the sample volume taken (corrected to standard 
conditions) will exceed the required minimum total gas sample volume. 
The latter is based on an approximate average sampling rate.
    8.2.5 The sampling time at each point shall be the same. It is 
recommended that the number of minutes sampled at each point be an 
integer or an integer plus one-half minute, in order to eliminate 
timekeeping errors.
    8.2.6 In some circumstances (e.g., batch cycles), it may be 
necessary to sample for shorter times at the traverse points and to 
obtain smaller gas sample volumes. In these cases, the Administrator's 
approval must first be obtained.
    8.3 Preparation of sampling train.
    8.3.1 During preparation and assembly of the sampling train, keep 
all openings where contamination can occur covered until just prior to 
assembly or until sampling is about to begin. Place l00 ml of water in 
each of the first two impingers, leave the third impinger empty, and 
transfer approximately 200 to 300 g of preweighed silica gel from its 
container to the fourth impinger. More silica gel may be used, but care 
should be taken to ensure that it is not entrained and carried out from 
the impinger during sampling. Place the container in a clean place for 
later use in the sample recovery. Alternatively, the weight of the 
silica gel plus impinger may be determined to the nearest 0.5 g and 
recorded.
    8.3.2 Using a tweezer or clean disposable surgical gloves, place a 
labeled (identified) and weighed filter in the filter holder. Be sure 
that the filter is properly centered and the gasket properly placed so 
as to prevent the sample gas stream from circumventing the filter. Check 
the filter for tears after assembly is completed.
    8.3.3 When glass liners are used, install the selected nozzle using 
a Viton A 0-ring when stack temperatures are less than 260 [deg]C (500 
[deg]F) and an asbestos string gasket when temperatures are higher. See 
APTD-0576 for details. Mark the probe with heat-resistant tape or by 
some other method to denote the proper distance into the stack or duct 
for each sampling point.
    8.3.4 Set up the train as in Figure 5-1 of Method 5, 40 CFR part 60, 
appendix A, using (if necessary) a very light coat of silicone grease on 
all ground glass joints, greasing only the outer portion (see APTD-0576) 
to avoid possibility of contamination by the silicone grease. Subject to 
the approval of the Administrator, a glass cyclone may be used between 
the probe and filter holder when the total particulate catch is expected 
to exceed 100 mg or when water droplets are present in the stack gas.
    8.3.5 Place crushed ice around the impingers.
    8.4 Leak-check procedures.
    8.4.1 Leak check of metering system shown in Figure 5-1 of Method 5, 
40 CFR part 60, appendix A. That portion of the sampling train from the 
pump to the orifice meter should be leak-checked prior to initial use 
and after each shipment. Leakage after the pump will result in less 
volume being recorded than is actually sampled. The following procedure 
is suggested (see Figure 5-2 of Method 5, 40 CFR part 60, appendix A): 
Close the main valve on the meter box. Insert a one-hole rubber stopper 
with rubber tubing attached into the orifice exhaust pipe. Disconnect 
and vent the low side of the orifice manometer. Close off the low side 
orifice tap. Pressurize the system to 13 to 18 cm (5 to 7 in.) water 
column by blowing into the rubber tubing. Pinch off the tubing, and 
observe the manometer for 1 minute. A loss of pressure on the manometer 
indicates a leak in the meter box; leaks, if present, must be corrected.
    8.4.2 Pretest leak check. A pretest leak-check is recommended but 
not required. If the pretest leak-check is conducted, the following 
procedure should be used.
    8.4.2.1 After the sampling train has been assembled, turn on and set 
the filter and probe heating systems to the desired operating 
temperatures. Allow time for the temperatures to stabilize. If a Viton A 
0-ring or other leak-free connection is used in assembling the probe 
nozzle to the probe liner, leak-check the train at the sampling site by 
plugging the nozzle and pulling a 380 mm (15 in.) Hg vacuum.

    Note: A lower vacuum may be used, provided that it is not exceeded 
during the test.

    8.4.2.2 If an asbestos string is used, do not connect the probe to 
the train during the leak check. Instead, leak-check the train by first 
plugging the inlet to the filter holder (cyclone, if applicable) and 
pulling a 380 mm (15 in.) Hg vacuum. (See NOTE in section

[[Page 1063]]

8.4.2.1 of this method). Then connect the probe to the train and perform 
the leak check at approximately 25 mm (1 in.) Hg vacuum; alternatively, 
the probe may be leak-checked with the rest of the sampling train, in 
one step, at 380 mm (15 in.) Hg vacuum. Leakage rates in excess of 4 
percent of the average sampling rate or 0.00057 m\3\/min (0.02 cfm), 
whichever is less, are unacceptable.
    8.4.2.3 The following leak check instructions for the sampling train 
described in APTD-0576 and APTD-058l may be helpful. Start the pump with 
the bypass valve fully open and the coarse adjust valve completely 
closed. Partially open the coarse adjust valve and slowly close the 
bypass valve until the desired vacuum is reached. Do not reverse the 
direction of the bypass valve, as this will cause water to back up into 
the filter holder. If the desired vacuum is exceeded, either leak-check 
at this higher vacuum or end the leak check as shown below and start 
over.
    8.4.2.4 When the leak check is completed, first slowly remove the 
plug from the inlet to the probe, filter holder, or cyclone (if 
applicable) and immediately turn off the vacuum pump. This prevents the 
water in the impingers from being forced backward into the filter holder 
and the silica gel from being entrained backward into the third 
impinger.
    8.4.3 Leak checks during sample run. If, during the sampling run, a 
component (e.g., filter assembly or impinger) change becomes necessary, 
a leak check shall be conducted immediately before the change is made. 
The leak check shall be done according to the procedure outlined in 
section 8.4.2 of this method, except that it shall be done at a vacuum 
equal to or greater than the maximum value recorded up to that point in 
the test. If the leakage rate is found to be no greater than 0.00057 
m\3\/min (0.02 cfm) or 4 percent of the average sampling rate (whichever 
is less), the results are acceptable, and no correction will need to be 
applied to the total volume of dry gas metered; if, however, a higher 
leakage rate is obtained, either record the leakage rate and plan to 
correct the sample volume as shown in section 12.3 of this method or 
void the sample run.

    Note: Immediately after component changes, leak checks are optional; 
if such leak checks are done, the procedure outlined in section 8.4.2 of 
this method should be used.

    8.4.4 Post-test leak check. A leak check is mandatory at the 
conclusion of each sampling run. The leak check shall be performed in 
accordance with the procedures outlined in section 8.4.2 of this method, 
except that it shall be conducted at a vacuum equal to or greater than 
the maximum value reached during the sampling run. If the leakage rate 
is found to be no greater than 0.00057 m\3\/min (0.02 cfm) or 4 percent 
of the average sampling rate (whichever is less), the results are 
acceptable, and no correction need be applied to the total volume of dry 
gas metered. If, however, a higher leakage rate is obtained, either 
record the leakage rate and correct the sample volume, as shown in 
section 12.4 of this method, or void the sampling run.
    8.5 Sampling train operation. During the sampling run, maintain an 
isokinetic sampling rate (within l0 percent of true isokinetic unless 
otherwise specified by the Administrator) and a temperature around the 
filter of 120 14 [deg]C (248 25 [deg]F), or such other temperature as 
specified by an applicable subpart of the standards or approved by the 
Administrator.
    8.5.1 For each run, record the data required on a data sheet such as 
the one shown in Figure 5-2 of Method 5, 40 CFR part 60, appendix A. Be 
sure to record the initial reading. Record the DGM readings at the 
beginning and end of each sampling time increment, when changes in flow 
rates are made, before and after each leak-check, and when sampling is 
halted. Take other readings indicated by Figure 5-2 of Method 5, 40 CFR 
part 60, appendix A at least once at each sample point during each time 
increment and additional readings when significant changes (20 percent 
variation in velocity head readings) necessitate additional adjustments 
in flow rate. Level and zero the manometer. Because the manometer level 
and zero may drift due to vibrations and temperature changes, make 
periodic checks during the traverse.
    8.5.2 Clean the portholes prior to the test run to minimize the 
chance of sampling deposited material. To begin sampling, remove the 
nozzle cap and verify that the filter and probe heating systems are up 
to temperature and that the pitot tube and probe are properly 
positioned. Position the nozzle at the first traverse point with the tip 
pointing directly into the gas stream. Immediately start the pump and 
adjust the flow to isokinetic conditions. Nomographs are available, 
which aid in the rapid adjustment of the isokinetic sampling rate 
without excessive computations. These nomographs are designed for use 
when the Type S pitot tube coefficient (Cp) is 0.85  
0.02 and the stack gas equivalent density (dry molecular weight) is 29 
[plusmn] 4. APTD-0576 details the procedure for using the nomographs. If 
Cp and Md are outside the above-stated ranges, do 
not use the nomographs unless appropriate steps (see Reference 7 in 
section 17.0 of this method) are taken to compensate for the deviations.
    8.5.3 When the stack is under significant negative pressure (height 
of impinger stem), close the coarse adjust valve before inserting the 
probe into the stack to prevent water from backing into the filter 
holder. If necessary, the pump may be turned on with the coarse adjust 
valve closed.

[[Page 1064]]

    8.5.4 When the probe is in position, block off the openings around 
the probe and porthole to prevent unrepresentative dilution of the gas 
stream.
    8.5.5 Traverse the stack cross-section, as required by Method 1, 40 
CFR part 60, appendix A or as specified by the Administrator, being 
careful not to bump the probe nozzle into the stack walls when sampling 
near the walls or when removing or inserting the probe through the 
portholes; this minimizes the chance of extracting deposited material.
    8.5.6 During the test run, make periodic adjustments to keep the 
temperature around the filter holder at the proper level; add more ice 
and, if necessary, salt to maintain a temperature of less than 20 [deg]C 
(68 [deg]F) at the condenser/silica gel outlet. Also, periodically check 
the level and zero of the manometer.
    8.5.7 If the pressure drop across the filter becomes too high, 
making isokinetic sampling difficult to maintain, the filter may be 
replaced in the midst of the sample run. It is recommended that another 
complete filter assembly be used rather than attempting to change the 
filter itself. Before a new filter assembly is installed, conduct a leak 
check (see section 8.4.3 of this method). The total PM weight shall 
include the summation of the filter assembly catches.
    8.5.8 A single train shall be used for the entire sample run, except 
in cases where simultaneous sampling is required in two or more separate 
ducts or at two or more different locations within the same duct, or in 
cases where equipment failure necessitates a change of trains. In all 
other situations, the use of two or more trains will be subject to the 
approval of the Administrator.

    Note: When two or more trains are used, separate analyses of the 
front-half and (if applicable) impinger catches from each train shall be 
performed, unless identical nozzle sizes were used in all trains, in 
which case the front-half catches from the individual trains may be 
combined (as may the impinger catches) and one analysis of the front-
half catch and one analysis of the impinger catch may be performed.

    8.5.9 At the end of the sample run, turn off the coarse adjust 
valve, remove the probe and nozzle from the stack, turn off the pump, 
record the final DGM reading, and then conduct a post-test leak check, 
as outlined in section 8.4.4 of this method. Also leak-check the pitot 
lines as described in section 8.1 of Method 2, 40 CFR part 60, appendix 
A. The lines must pass this leak check in order to validate the velocity 
head data.
    8.6 Calculation of percent isokinetic. Calculate percent isokinetic 
(see Calculations, section 12.12 of this method) to determine whether a 
run was valid or another test run should be made. If there was 
difficulty in maintaining isokinetic rates because of source conditions, 
consult the Administrator for possible variance on the isokinetic rates.
    8.7 Sample recovery.
    8.7.1 Proper cleanup procedure begins as soon as the probe is 
removed from the stack at the end of the sampling period. Allow the 
probe to cool.
    8.7.2 When the probe can be safely handled, wipe off all external PM 
near the tip of the probe nozzle and place a cap over it to prevent 
losing or gaining PM. Do not cap off the probe tip tightly while the 
sampling train is cooling down. This would create a vacuum in the filter 
holder, thus drawing water from the impingers into the filter holder.
    8.7.3 Before moving the sample train to the cleanup site, remove the 
probe from the sample train, wipe off the silicone grease, and cap the 
open outlet of the probe. Be careful not to lose any condensate that 
might be present. Wipe off the silicone grease from the filter inlet 
where the probe was fastened and cap it. Remove the umbilical cord from 
the last impinger and cap the impinger. If a flexible line is used 
between the first impinger or condenser and the filter holder, 
disconnect the line at the filter holder and let any condensed water or 
liquid drain into the impingers or condenser. After wiping off the 
silicone grease, cap off the filter holder outlet and impinger inlet. 
Ground-glass stoppers, plastic caps, or serum caps may be used to close 
these openings.
    8.7.4 Transfer the probe and filter-impinger assembly to the cleanup 
area. This area should be clean and protected from the wind so that the 
chances of contaminating or losing the sample will be minimized.
    8.7.5 Save a portion of the acetone and methylene chloride used for 
cleanup as blanks. Take 200 ml of each solvent directly from the wash 
bottle being used and place it in glass sample containers labeled 
``acetone blank'' and ``methylene chloride blank,'' respectively.
    8.7.6 Inspect the train prior to and during disassembly and note any 
abnormal conditions. Treat the samples as follows:
    8.7.6.1 Container No. 1. Carefully remove the filter from the filter 
holder, and place it in its identified petri dish container. Use a pair 
of tweezers and/or clean disposable surgical gloves to handle the 
filter. If it is necessary to fold the filter, do so such that the PM 
cake is inside the fold. Using a dry nylon bristle brush and/or a sharp-
edged blade, carefully transfer to the petri dish any PM and/or filter 
fibers that adhere to the filter holder gasket. Seal the container.
    8.7.6.2 Container No. 2. Taking care to see that dust on the outside 
of the probe or other exterior surfaces does not get into the sample, 
quantitatively recover PM or any condensate from the probe nozzle, probe 
fitting, probe liner, and front half of the filter holder by washing 
these components with acetone

[[Page 1065]]

and placing the wash in a glass container. Perform the acetone rinse as 
follows:
    8.7.6.2.1 Carefully remove the probe nozzle and clean the inside 
surface by rinsing with acetone from a wash bottle and brushing with a 
nylon bristle brush. Brush until the acetone rinse shows no visible 
particles, after which make a final rinse of the inside surface with 
acetone.
    8.7.6.2.2 Brush and rinse the inside parts of the Swagelok fitting 
with acetone in a similar way until no visible particles remain.
    8.7.6.2.3 Rinse the probe liner with acetone by tilting and rotating 
the probe while squirting acetone into its upper end so that all inside 
surfaces are wetted with acetone. Let the acetone drain from the lower 
end into the sample container. A funnel (glass or polyethylene) may be 
used to aid in transferring liquid washes to the container. Follow the 
acetone rinse with a probe brush. Hold the probe in an inclined 
position, squirt acetone into the upper end as the probe brush is being 
pushed with a twisting action through the probe, hold a sample container 
under the lower end of the probe, and catch any acetone and PM that is 
brushed from the probe. Run the brush through the probe three times or 
more until no visible PM is carried out with the acetone or until none 
remains in the probe liner on visual inspection. With stainless steel or 
other metal probes, run the brush through in the above-described manner 
at least six times, since metal probes have small crevices in which PM 
can be entrapped. Rinse the brush with acetone and quantitatively 
collect these washings in the sample container. After the brushing, make 
a final acetone rinse of the probe as described above.
    8.7.6.2.4 It is recommended that two people clean the probe to 
minimize sample losses. Between sampling runs, keep brushes clean and 
protected from contamination.
    8.7.6.2.5 After ensuring that all joints have been wiped clean of 
silicone grease, clean the inside of the front half of the filter holder 
by rubbing the surfaces with a nylon bristle brush and rinsing with 
acetone. Rinse each surface three times or more if needed to remove 
visible particulate. Make a final rinse of the brush and filter holder. 
Carefully rinse out the glass cyclone also (if applicable).
    8.7.6.2.6 After rinsing the nozzle, probe, and front half of the 
filter holder with acetone, repeat the entire procedure with methylene 
chloride and save in a separate No. 2M container.
    8.7.6.2.7 After acetone and methylene chloride washings and PM have 
been collected in the proper sample containers, tighten the lid on the 
sample containers so that acetone and methylene chloride will not leak 
out when it is shipped to the laboratory. Mark the height of the fluid 
level to determine whether leakage occurs during transport. Label each 
container to identify clearly its contents.
    8.7.6.3 Container No. 3. Note the color of the indicating silica gel 
to determine whether it has been completely spent, and make a notation 
of its condition. Transfer the silica gel from the fourth impinger to 
its original container and seal the container. A funnel may make it 
easier to pour the silica gel without spilling. A rubber policeman may 
be used as an aid in removing the silica gel from the impinger. It is 
not necessary to remove the small amount of dust particles that may 
adhere to the impinger wall and are difficult to remove. Since the gain 
in weight is to be used for moisture calculations, do not use any water 
or other liquids to transfer the silica gel. If a balance is available 
in the field, follow the procedure for Container No. 3 in section 11.2.3 
of this method.
    8.7.6.4 Impinger water. Treat the impingers as follows:
    8.7.6.4.1 Make a notation of any color or film in the liquid catch. 
Measure the liquid that is in the first three impingers to within 1 ml 
by using a graduated cylinder or by weighing it to within 0.5 g by using 
a balance (if one is available). Record the volume or weight of liquid 
present. This information is required to calculate the moisture content 
of the effluent gas.
    8.7.6.4.2 Following the determination of the volume of liquid 
present, rinse the back half of the train with water, add it to the 
impinger catch, and store it in a container labeled 3W (water).
    8.7.6.4.3 Following the water rinse, rinse the back half of the 
train with acetone to remove the excess water to enhance subsequent 
organic recovery with methylene chloride and quantitatively recover to a 
container labeled 3S (solvent) followed by at least three sequential 
rinsings with aliquots of methylene chloride. Quantitatively recover to 
the same container labeled 3S. Record separately the amount of both 
acetone and methylene chloride used to the nearest 1 ml or 0.5g.

    Note: Because the subsequent analytical finish is gravimetric, it is 
okay to recover both solvents to the same container. This would not be 
recommended if other analytical finishes were required.

    8.8 Sample transport. Whenever possible, containers should be 
shipped in such a way that they remain upright at all times.

------------------------------------------------------------------------

    9.2 Volume metering system checks. The following quality control 
procedures are suggested to check the volume metering system calibration 
values at the field test site prior to sample collection. These 
procedures are optional.
    9.2.1 Meter orifice check. Using the calibration data obtained 
during the calibration procedure described in section 10.3 of this 
method, determine the [Delta]Ha for the metering system 
orifice. The [Delta]Ha is the orifice pressure differential 
in units of in. H20 that correlates to 0.75 cfm of air at 528 
[deg]R and 29.92 in. Hg. The [Delta]Ha is calculated as 
follows:
[GRAPHIC] [TIFF OMITTED] TR07OC97.008

Where

0.0319 = (0.0567 in. Hg/ [deg]R)(0.75 cfm)\2\;
[Delta]H = Average pressure differential across the orifice meter, in. 
          H20;
Tm = Absolute average DGM temperature, [deg]R;
[Theta] = Total sampling time, min;
Pbar = Barometric pressure, in. Hg;
Y = DGM calibration factor, dimensionless;
Vm = Volume of gas sample as measured by DGM, dcf.

    9.2.1.1 Before beginning the field test (a set of three runs usually 
constitutes a field test), operate the metering system (i.e., pump, 
volume meter, and orifice) at the [Delta]Ha pressure 
differential for 10 minutes. Record the volume collected, the DGM 
temperature, and the barometric pressure. Calculate a DGM calibration 
check value, Yc, as follows:
[GRAPHIC] [TIFF OMITTED] TR07OC97.009

Where

Yc = DGM calibration check value, dimensionless;
10 = Run time, min.

    9.2.1.2 Compare the Yc value with the dry gas meter 
calibration factor Y to determine that: 0.97 Y < Yc < 1.03Y. 
If the Yc value is not within this range, the volume metering 
system should be investigated before beginning the test.
    9.2.2 Calibrated critical orifice. A calibrated critical orifice, 
calibrated against a wet test meter or spirometer and designed to be 
inserted at the inlet of the sampling meter box, may be used as a 
quality control check by following the procedure of section 16.2 of this 
method.

                  10.0 Calibration and Standardization.

    Note: Maintain a laboratory log of all calibrations.

    10.1 Probe nozzle. Probe nozzles shall be calibrated before their 
initial use in the field. Using a micrometer, measure the ID of the 
nozzle to the nearest 0.025 mm (0.001 in.). Make three separate 
measurements using different diameters each time, and obtain the average 
of the measurements. The difference between the high and low numbers 
shall not exceed 0.1 mm (0.004 in.). When nozzles become nicked, dented, 
or corroded, they shall be reshaped, sharpened, and recalibrated before 
use. Each nozzle shall be permanently and uniquely identified.
    10.2 Pitot tube assembly. The Type S pitot tube assembly shall be 
calibrated according to the procedure outlined in section 10.1 of Method 
2, 40 CFR part 60, appendix A.
    10.3 Metering system.
    10.3.1 Calibration prior to use. Before its initial use in the 
field, the metering system shall be calibrated as follows: Connect the 
metering system inlet to the outlet of a wet test meter that is accurate 
to within 1 percent. Refer to Figure 5-5 of Method 5, 40 CFR part 60, 
appendix A. The wet test meter should have a capacity of 30 liters/
revolution (1 ft3/rev). A spirometer of 400 liters (14 
ft3) or more capacity, or equivalent, may be used for this 
calibration, although a wet test meter is usually more practical. The 
wet test meter should be periodically calibrated with a spirometer or a 
liquid displacement meter to ensure the accuracy of the wet test meter. 
Spirometers or wet test meters of other sizes may be used, provided that 
the specified accuracies of the procedure are maintained. Run the 
metering system pump for about 15 minutes with the orifice manometer 
indicating a median reading, as expected in field use, to allow the pump 
to warm up and to permit the interior surface of the wet test meter to 
be thoroughly wetted. Then, at each of a minimum of three orifice 
manometer settings, pass an exact quantity of gas through the wet test 
meter and note the gas volume indicated by the DGM. Also note the

[[Page 1067]]

barometric pressure and the temperatures of the wet test meter, the 
inlet of the DGM, and the outlet of the DGM. Select the highest and 
lowest orifice settings to bracket the expected field operating range of 
the orifice. Use a minimum volume of 0.15 m3 (5 cf) at all 
orifice settings. Record all the data on a form similar to Figure 5-6 of 
Method 5, 40 CFR part 60, appendix A, and calculate Y (the DGM 
calibration factor) and [Delta]Ha (the orifice calibration 
factor) at each orifice setting, as shown on Figure 5-6 of Method 5, 40 
CFR part 60, appendix A. Allowable tolerances for individual Y and 
[Delta]Ha values are given in Figure 5-6 of Method 5, 40 CFR 
part 60, appendix A. Use the average of the Y values in the calculations 
in section 12 of this method.
    10.3.1.1 Before calibrating the metering system, it is suggested 
that a leak check be conducted. For metering systems having diaphragm 
pumps, the normal leak check procedure will not detect leakages within 
the pump. For these cases the following leak check procedure is 
suggested: make a 10-minute calibration run at 0.00057 m3/min 
(0.02 cfm); at the end of the run, take the difference of the measured 
wet test meter and DGM volumes; divide the difference by 10 to get the 
leak rate. The leak rate should not exceed 0.00057 m3/min 
(0.02 cfm).
    10.3.2 Calibration after use. After each field use, the calibration 
of the metering system shall be checked by performing three calibration 
runs at a single, intermediate orifice setting (based on the previous 
field test) with the vacuum set at the maximum value reached during the 
test series. To adjust the vacuum, insert a valve between the wet test 
meter and the inlet of the metering system. Calculate the average value 
of the DGM calibration factor. If the value has changed by more than 5 
percent, recalibrate the meter over the full range of orifice settings, 
as previously detailed.

    Note: Alternative procedures, e.g., rechecking the orifice meter 
coefficient, may be used, subject to the approval of the Administrator.

    10.3.3 Acceptable variation in calibration. If the DGM coefficient 
values obtained before and after a test series differ by more than 5 
percent, either the test series shall be voided or calculations for the 
test series shall be performed using whichever meter coefficient value 
(i.e., before or after) gives the lower value of total sample volume.
    10.4 Probe heater calibration. Use a heat source to generate air 
heated to selected temperatures that approximate those expected to occur 
in the sources to be sampled. Pass this air through the probe at a 
typical sample flow rate while measuring the probe inlet and outlet 
temperatures at various probe heater settings. For each air temperature 
generated, construct a graph of probe heating system setting versus 
probe outlet temperature. The procedure outlined in APTD-0576 can also 
be used. Probes constructed according to APTD-0581 need not be 
calibrated if the calibration curves in APTD-0576 are used. Also, probes 
with outlet temperature monitoring capabilities do not require 
calibration.

    Note: The probe heating system shall be calibrated before its 
initial use in the field.

    10.5 Temperature sensors. Use the procedure in section 10.3 of 
Method 2, 40 CFR part 60, appendix A to calibrate in-stack temperature 
sensors. Dial thermometers, such as are used for the DGM and condenser 
outlet, shall be calibrated against mercury-in-glass thermometers.
    10.6 Barometer. Calibrate against a mercury barometer.

                       11.0 Analytical Procedure.

    11.1 Record the data required on a sheet such as the one shown in 
Figure 315-1 of this method.
    11.2 Handle each sample container as follows:
    11.2.1 Container No. 1.
    11.2.1.1 PM analysis. Leave the contents in the shipping container 
or transfer the filter and any loose PM from the sample container to a 
tared glass weighing dish. Desiccate for 24 hours in a desiccator 
containing anhydrous calcium sulfate. Weigh to a constant weight and 
report the results to the nearest 0.1 mg. For purposes of this section, 
the term ``constant weight'' means a difference of no more than 0.5 mg 
or 1 percent of total weight less tare weight, whichever is greater, 
between two consecutive weighings, with no less than 6 hours of 
desiccation time between weighings (overnight desiccation is a common 
practice). If a third weighing is required and it agrees within 
[plusmn]0.5 mg, then the results of the second weighing should be used. 
For quality assurance purposes, record and report each individual 
weighing; if more than three weighings are required, note this in the 
results for the subsequent MCEM results.
    11.2.1.2 MCEM analysis. Transfer the filter and contents 
quantitatively into a beaker. Add 100 ml of methylene chloride and cover 
with aluminum foil. Sonicate for 3 minutes then allow to stand for 20 
minutes. Set up the filtration apparatus. Decant the solution into a 
clean Buchner fritted funnel. Immediately pressure filter the solution 
through the tube into another clean, dry beaker. Continue decanting and 
pressure filtration until all the solvent is transferred. Rinse the 
beaker and filter with 10 to 20 ml methylene chloride, decant into the 
Buchner fritted funnel and pressure filter. Place the beaker on a low-
temperature hot plate (maximum 40 [deg]C) and slowly evaporate almost to

[[Page 1068]]

dryness. Transfer the remaining last few milliliters of solution 
quantitatively from the beaker (using at least three aliquots of 
methylene chloride rinse) to a tared clean dry aluminum dish and 
evaporate to complete dryness. Remove from heat once solvent is 
evaporated. Reweigh the dish after a 30-minute equilibrium in the 
balance room and determine the weight to the nearest 0.1 mg. Conduct a 
methylene chloride blank run in an identical fashion.
    11.2.2 Container No. 2.
    11.2.2.1 PM analysis. Note the level of liquid in the container, and 
confirm on the analysis sheet whether leakage occurred during transport. 
If a noticeable amount of leakage has occurred, either void the sample 
or use methods, subject to the approval of the Administrator, to correct 
the final results. Measure the liquid in this container either 
volumetrically to [plusmn]1 ml or gravimetrically to 1[plusmn]0.5 g. 
Transfer the contents to a tared 250 ml beaker and evaporate to dryness 
at ambient temperature and pressure. Desiccate for 24 hours, and weigh 
to a constant weight. Report the results to the nearest 0.1 mg.
    11.2.2.2 MCEM analysis. Add 25 ml methylene chloride to the beaker 
and cover with aluminum foil. Sonicate for 3 minutes then allow to stand 
for 20 minutes; combine with contents of Container No. 2M and pressure 
filter and evaporate as described for Container 1 in section 11.2.1.2 of 
this method.

                         Notes for MCEM Analysis

    1. Light finger pressure only is necessary on 24/40 adaptor. A 
Chemplast adapter 15055-240 has been found satisfactory.
    2. Avoid aluminum dishes made with fluted sides, as these may 
promote solvent ``creep,'' resulting in possible sample loss.
    3. If multiple samples are being run, rinse the Buchner fritted 
funnel twice between samples with 5 ml solvent using pressure 
filtration. After the second rinse, continue the flow of air until the 
glass frit is completely dry. Clean the Buchner fritted funnels 
thoroughly after filtering five or six samples.

    11.2.3 Container No. 3. Weigh the spent silica gel (or silica gel 
plus impinger) to the nearest 0.5 g using a balance. This step may be 
conducted in the field.
    11.2.4 Container 3W (impinger water).
    11.2.4.1 MCEM analysis. Transfer the solution into a 1,000 ml 
separatory funnel quantitatively with methylene chloride washes. Add 
enough solvent to total approximately 50 ml, if necessary. Shake the 
funnel for 1 minute, allow the phases to separate, and drain the solvent 
layer into a 250 ml beaker. Repeat the extraction twice. Evaporate with 
low heat (less than 40 [deg]C) until near dryness. Transfer the 
remaining few milliliters of solvent quantitatively with small solvent 
washes into a clean, dry, tared aluminum dish and evaporate to dryness. 
Remove from heat once solvent is evaporated. Reweigh the dish after a 
30-minute equilibration in the balance room and determine the weight to 
the nearest 0.1 mg.

    11.2.5 Container 3S (solvent).
    11.2.5.1 MCEM analysis. Transfer the mixed solvent to 250 ml 
beaker(s). Evaporate and weigh following the procedures detailed for 
container 3W in section 11.2.4 of this method.
    11.2.6 Blank containers. Measure the distilled water, acetone, or 
methylene chloride in each container either volumetrically or 
gravimetrically. Transfer the ``solvent'' to a tared 250 ml beaker, and 
evaporate to dryness at ambient temperature and pressure. (Conduct a 
solvent blank on the distilled deionized water blank in an identical 
fashion to that described in section 11.2.4.1 of this method.) Desiccate 
for 24 hours, and weigh to a constant weight. Report the results to the 
nearest 0.l mg.

    Note: The contents of Containers No. 2, 3W, and 3M as well as the 
blank containers may be evaporated at temperatures higher than ambient. 
If evaporation is done at an elevated temperature, the temperature must 
be below the boiling point of the solvent; also, to prevent ``bumping,'' 
the evaporation process must be closely supervised, and the contents of 
the beaker must be swirled occasionally to maintain an even temperature. 
Use extreme care, as acetone and methylene chloride are highly flammable 
and have a low flash point.

                  12.0 Data Analysis and Calculations.

in the Bibliography may be used to make acceptability judgments. If 
``I'' is judged to be unacceptable, reject the results, and repeat the 
test.

    16.1 Dry gas meter as a calibration standard. A DGM may be used as a 
calibration standard for volume measurements in place of the wet test 
meter specified in section 16.1 of this method, provided that it is 
calibrated initially and recalibrated periodically as follows:
    16.1.1 Standard dry gas meter calibration.
    16.1.1.1. The DGM to be calibrated and used as a secondary reference 
meter should be of high quality and have an appropriately sized 
capacity, e.g., 3 liters/rev (0.1 ft \3\/rev). A spirometer (400 liters 
or more capacity), or equivalent, may be used for this calibration, 
although a wet test meter is usually more practical. The wet test meter 
should have a capacity of 30 liters/rev (1 ft \3\/rev) and be capable of 
measuring volume to within 1.0 percent; wet test meters should be 
checked against a spirometer or a liquid displacement meter to ensure 
the accuracy of the wet test meter. Spirometers or wet test meters of 
other sizes may be used, provided that the specified accuracies of the 
procedure are maintained.
    16.1.1.2 Set up the components as shown in Figure 5-7 of Method 5, 
40 CFR part 60, appendix A. A spirometer, or equivalent, may be used in 
place of the wet test meter in the system. Run the pump for at least 5 
minutes at a flow rate of about 10 liters/min (0.35 cfm) to condition 
the interior surface of the wet test meter. The pressure drop indicated 
by the manometer at the inlet side of the DGM should be minimized (no 
greater than 100 mm H2O [4 in. H2O] at a flow rate 
of 30 liters/min [1 cfm]). This can be accomplished by using large-
diameter tubing connections and straight pipe fittings.
    16.1.1.3 Collect the data as shown in the example data sheet (see 
Figure 5-8 of Method 5, 40 CFR part 60, appendix A). Make triplicate 
runs at each of the flow rates and at no less than five different flow 
rates. The range of flow rates should be between 10 and 34 liters/min 
(0.35 and 1.2 cfm) or over the expected operating range.
    16.1.1.4 Calculate flow rate, Q, for each run using the wet test 
meter volume, Vw, and the run time, q. Calculate the DGM 
coefficient, Yds, for each run. These calculations are as 
follows:
[GRAPHIC] [TIFF OMITTED] TR07OC97.017

[GRAPHIC] [TIFF OMITTED] TR07OC97.018

Where

K1 = 0.3858 for international system of units (SI); 17.64 for 
          English units;
Pbar = Barometric pressure, mm Hg (in Hg);
Vw = Wet test meter volume, liter (ft\3\);
tw = Average wet test meter temperature, [deg]C ( [deg]F);

[[Page 1072]]

tstd = 273 [deg]C for SI units; 460'F for English units;
[Theta] = Run time, min;
tds = Average dry gas meter temperature, [deg]C ( [deg]F);
Vds = Dry gas meter volume, liter (ft\3\);
[Delta]p = Dry gas meter inlet differential pressure, mm H2O 
          (in H2O).

    16.1.1.5 Compare the three Yds values at each of the flow 
rates and determine the maximum and minimum values. The difference 
between the maximum and minimum values at each flow rate should be no 
greater than 0.030. Extra sets of triplicate runs may be made in order 
to complete this requirement. In addition, the meter coefficients should 
be between 0.95 and 1.05. If these specifications cannot be met in three 
sets of successive triplicate runs, the meter is not suitable as a 
calibration standard and should not be used as such. If these 
specifications are met, average the three Yds values at each 
flow rate resulting in five average meter coefficients, Yds.
    16.1.1.6 Prepare a curve of meter coefficient, Yds, 
versus flow rate, Q, for the DGM. This curve shall be used as a 
reference when the meter is used to calibrate other DGMs and to 
determine whether recalibration is required.
    16.1.2 Standard dry gas meter recalibration.
    16.1.2.1 Recalibrate the standard DGM against a wet test meter or 
spirometer annually or after every 200 hours of operation, whichever 
comes first. This requirement is valid provided the standard DGM is kept 
in a laboratory and, if transported, cared for as any other laboratory 
instrument. Abuse to the standard meter may cause a change in the 
calibration and will require more frequent recalibrations.
    16.1.2.2 As an alternative to full recalibration, a two-point 
calibration check may be made. Follow the same procedure and equipment 
arrangement as for a full recalibration, but run the meter at only two 
flow rates (suggested rates are 14 and 28 liters/min [0.5 and 1.0 cfm]). 
Calculate the meter coefficients for these two points, and compare the 
values with the meter calibration curve. If the two coefficients are 
within 1.5 percent of the calibration curve values at the same flow 
rates, the meter need not be recalibrated until the next date for a 
recalibration check.
    6.2 Critical orifices as calibration standards. Critical orifices 
may be used as calibration standards in place of the wet test meter 
specified in section 10.3 of this method, provided that they are 
selected, calibrated, and used as follows:
    16.2.1 Selection of critical orifices.
    16.2.1.1 The procedure that follows describes the use of hypodermic 
needles or stainless steel needle tubing that has been found suitable 
for use as critical orifices. Other materials and critical orifice 
designs may be used provided the orifices act as true critical orifices; 
i.e., a critical vacuum can be obtained, as described in section 
7.2.2.2.3 of Method 5, 40 CFR part 60, appendix A. Select five critical 
orifices that are appropriately sized to cover the range of flow rates 
between 10 and 34 liters/min or the expected operating range. Two of the 
critical orifices should bracket the expected operating range. A minimum 
of three critical orifices will be needed to calibrate a Method 5 DGM; 
the other two critical orifices can serve as spares and provide better 
selection for bracketing the range of operating flow rates. The needle 
sizes and tubing lengths shown in Table 315-1 give the approximate flow 
rates indicated in the table.
    16.2.1.2 These needles can be adapted to a Method 5 type sampling 
train as follows: Insert a serum bottle stopper, 13x20 mm sleeve type, 
into a 0.5 in Swagelok quick connect. Insert the needle into the stopper 
as shown in Figure 5-9 of Method 5, 40 CFR part 60, appendix A.
    16.2.2 Critical orifice calibration. The procedure described in this 
section uses the Method 5 meter box configuration with a DGM as 
described in section 6.1.1.9 of this method to calibrate the critical 
orifices. Other schemes may be used, subject to the approval of the 
Administrator.
    16.2.2.1 Calibration of meter box. The critical orifices must be 
calibrated in the same configuration as they will be used; i.e., there 
should be no connections to the inlet of the orifice.
    16.2.2.1.1 Before calibrating the meter box, leak-check the system 
as follows: Fully open the coarse adjust valve and completely close the 
bypass valve. Plug the inlet. Then turn on the pump and determine 
whether there is any leakage. The leakage rate shall be zero; i.e., no 
detectable movement of the DGM dial shall be seen for 1 minute.
    16.2.2.1.2 Check also for leakages in that portion of the sampling 
train between the pump and the orifice meter. See section 5.6 of Method 
5, 40 CFR part 60, appendix A for the procedure; make any corrections, 
if necessary. If leakage is detected, check for cracked gaskets, loose 
fittings, worn 0-rings, etc. and make the necessary repairs.
    16.2.2.1.3 After determining that the meter box is leakless, 
calibrate the meter box according to the procedure given in section 5.3 
of Method 5, 40 CFR part 60, appendix A. Make sure that the wet test 
meter meets the requirements stated in section 7.1.1.1 of Method 5, 40 
CFR part 60, appendix A. Check the water level in the wet test meter. 
Record the DGM calibration factor, Y.
    16.2.2.2 Calibration of critical orifices. Set up the apparatus as 
shown in Figure 5-10 of Method 5, 40 CFR part 60, appendix A.
    16.2.2.2.1 Allow a warm-up time of 15 minutes. This step is 
important to equilibrate

[[Page 1073]]

the temperature conditions through the DGM.
    16.2.2.2.2 Leak-check the system as in section 7.2.2.1.1 of Method 
5, 40 CFR part 60, appendix A. The leakage rate shall be zero.
    16.2.2.2.3 Before calibrating the critical orifice, determine its 
suitability and the appropriate operating vacuum as follows: turn on the 
pump, fully open the coarse adjust valve, and adjust the bypass valve to 
give a vacuum reading corresponding to about half of atmospheric 
pressure. Observe the meter box orifice manometer reading, DH. Slowly 
increase the vacuum reading until a stable reading is obtained on the 
meter box orifice manometer. Record the critical vacuum for each 
orifice. Orifices that do not reach a critical value shall not be used.
    16.2.2.2.4 Obtain the barometric pressure using a barometer as 
described in section 6.1.2 of this method. Record the barometric 
pressure, Pbar, in mm Hg (in. Hg).
    16.2.2.2.5 Conduct duplicate runs at a vacuum of 25 to 50 mm Hg (1 
to 2 in. Hg) above the critical vacuum. The runs shall be at least 5 
minutes each. The DGM volume readings shall be in increments of complete 
revolutions of the DGM. As a guideline, the times should not differ by 
more than 3.0 seconds (this includes allowance for changes in the DGM 
temperatures) to achieve [plusmn]0.5 percent in K'. Record the 
information listed in Figure 5-11 of Method 5, 40 CFR part 60, appendix 
A.
    16.2.2.2.6 Calculate K' using Equation 315-11.
    [GRAPHIC] [TIFF OMITTED] TR07OC97.019
    
where

K' = Critical orifice coefficient, [m\3\)( [deg]K)1/2]/[(mm 
          Hg)(min)] '61' [(ft\3\)( [deg]R)1/2)]/[(in. 
          Hg)(min)]'61'
Tamb = Absolute ambient temperature, [deg]K ( [deg]R).

    16.2.2.2.7 Average the K' values. The individual K' values should 
not differ by more than [plusmn]0.5 percent from the average.
    16.2.3 Using the critical orifices as calibration standards.
    16.2.3.1 Record the barometric pressure.
    16.2.3.2 Calibrate the metering system according to the procedure 
outlined in sections 7.2.2.2.1 to 7.2.2.2.5 of Method 5, 40 CFR part 60, 
appendix A. Record the information listed in Figure 5-12 of Method 5, 40 
CFR part 60, appendix A.
    16.2.3.3 Calculate the standard volumes of air passed through the 
DGM and the critical orifices, and calculate the DGM calibration factor, 
Y, using the equations below:

Vm(std) = K1 Vm [Pbar + 
          ([Delta]H/13.6)]/Tm Eq. 315-12
Vcr(std) = K' (Pbar [Theta])/
          Tamb1/2 Eq. 315-13
Y = Vcr(std)/Vm(std) Eq. 315-14
where

Vcr(std) = Volume of gas sample passed through the critical 
          orifice, corrected to standard conditions, dscm (dscf).
K' = 0.3858 [deg]K/mm Hg for metric units
    = 17.64 [deg]R/in Hg for English units.

    16.2.3.4 Average the DGM calibration values for each of the flow 
rates. The calibration factor, Y, at each of the flow rates should not 
differ by more than [plusmn]2 percent from the average.
    16.2.3.5 To determine the need for recalibrating the critical 
orifices, compare the DGM Y factors obtained from two adjacent orifices 
each time a DGM is calibrated; for example, when checking orifice 13/
2.5, use orifices 12/10.2 and 13/5.1. If any critical orifice yields a 
DGM Y factor differing by more than 2 percent from the others, 
recalibrate the critical orifice according to section 7.2.2.2 of Method 
5, 40 CFR part 60, appendix A.

   Method 316--Sampling and Analysis for Formaldehyde Emissions From 
  Stationary Sources in the Mineral Wool and Wool Fiberglass Industries

                            1.0 Introduction

    This method is applicable to the determination of formaldehyde, CAS 
Registry number 50-00-0, from stationary sources in the mineral wool and 
wool fiber glass industries. High purity water is used to collect the 
formaldehyde. The formaldehyde concentrations in the stack samples are 
determined using the modified pararosaniline method. Formaldehyde can be 
detected as low as 8.8 x 1010 lbs/cu ft (11.3 ppbv) or as 
high as 1.8 x 103 lbs/cu ft (23,000,000 ppbv), at standard 
conditions over a 1 hour sampling period, sampling approximately 30 cu 
ft.

                          2.0 Summary of Method

    Gaseous and particulate pollutants are withdrawn isokinetically from 
an emission source and are collected in high purity water. Formaldehyde 
present in the emissions is highly soluble in high purity water. The 
high purity water containing formaldehyde is then analyzed using the 
modified pararosaniline method. Formaldehyde in the sample reacts with 
acidic pararosaniline, and the sodium sulfite, forming a purple 
chromophore. The intensity of the purple color, measured 
spectrophotometrically, provides an accurate and precise measure of the 
formaldehyde concentration in the sample.

                             3.0 Definitions

    See the definitions in the General Provisions of this Subpart.

                            4.0 Interferences

    Sulfite and cyanide in solution interfere with the pararosaniline 
method. A procedure to overcome the interference by each compound has 
been described by Miksch, et al.

                       6.0 Apparatus and Materials

    6.1 A schematic of the sampling train is shown in Figure 1. This 
sampling train configuration is adapted from EPA Method 5, 40 CFR part 
60, appendix A, procedures.


[[Page 1076]]


[GRAPHIC] [TIFF OMITTED] TR14JN99.050

    The sampling train consists of the following components: probe 
nozzle, probe liner, pitot tube, differential pressure gauge, impingers, 
metering system, barometer, and gas density determination equipment.
    6.1.1 Probe Nozzle: Quartz, glass, or stainless steel with sharp, 
tapered (30 [deg] angle) leading edge. The taper shall be on the outside 
to preserve a constant inner diameter. The nozzle shall be buttonhook or 
elbow design. A range of nozzle sizes suitable for isokinetic sampling 
should be available in increments of 0.15 cm (\1/16\ in), e.g., 0.32 to 
1.27 cm (\1/8\ to \1/2\ in), or larger if higher volume sampling trains 
are used. Each nozzle shall be calibrated according to the procedure 
outlined in Section 10.1.
    6.1.2 Probe Liner: Borosilicate glass or quartz shall be used for 
the probe liner. The probe shall be maintained at a temperature of 120 
[deg]C [plusmn] 14 [deg]C (248 [deg]F [plusmn] 25 [deg]F).
    6.1.3 Pitot Tube: The pitot tube shall be Type S, as described in 
Section 2.1 of EPA Method 2, 40 CFR part 60, appendix A, or any other 
appropriate device. The pitot tube shall be attached to the probe to 
allow constant monitoring of the stack gas velocity. The impact (high 
pressure) opening plane of the pitot tube shall be even with or above 
the nozzle entry plane (see Figure 2-6b, EPA Method 2, 40 CFR part 60, 
appendix A) during sampling. The Type S pitot tube assembly shall have a 
known coefficient, determined as outlined in Section 4 of EPA Method 2, 
40 CFR part 60, appendix A.
    6.1.4 Differential Pressure Gauge: The differential pressure gauge 
shall be an inclined manometer or equivalent device as described in 
Section 2.2 of EPA Method 2, 40 CFR part 60, appendix A. One manometer 
shall be used for velocity-head reading and the other for orifice 
differential pressure readings.
    6.1.5 Impingers: The sampling train requires a minimum of four 
impingers, connected as shown in Figure 1, with ground glass (or 
equivalent) vacuum-tight fittings. For the first, third, and fourth 
impingers, use the Greenburg-Smith design, modified by replacing the tip 
with a 1.3 cm inside diameters (\1/2\ in) glass tube extending to 1.3 cm 
(\1/2\ in) from the bottom of the flask. For the second impinger, use a 
Greenburg-Smith impinger with the standard tip. Place a thermometer 
capable of measuring temperature

[[Page 1077]]

to within 1 [deg]C (2 [deg]F) at the outlet of the fourth impinger for 
monitoring purposes.
    6.1.6 Metering System: The necessary components are a vacuum gauge, 
leak-free pump, thermometers capable of measuring temperatures within 3 
[deg]C (5.4 [deg]F), dry-gas meter capable of measuring volume to within 
1 percent, and related equipment as shown in Figure 1. At a minimum, the 
pump should be capable of 4 cfm free flow, and the dry gas meter should 
have a recording capacity of 0-999.9 cu ft with a resolution of 0.005 cu 
ft. Other metering systems may be used which are capable of maintaining 
sample volumes to within 2 percent. The metering system may be used in 
conjunction with a pitot tube to enable checks of isokinetic sampling 
rates.
    6.1.7 Barometer: The barometer may be mercury, aneroid, or other 
barometer capable of measuring atmospheric pressure to within 2.5 mm Hg 
(0.1 in Hg). In many cases, the barometric reading may be obtained from 
a nearby National Weather Service Station, in which case the station 
value (which is the absolute barometric pressure) is requested and an 
adjustment for elevation differences between the weather station and 
sampling point is applied at a rate of minus 2.5 mm Hg (0.1 in Hg) per 
30 m (100 ft) elevation increase (rate is plus 2.5 mm Hg per 30 m (100 
ft) of elevation decrease).
    6.1.8 Gas Density Determination Equipment: Temperature sensor and 
pressure gauge (as described in Sections 2.3 and 2.3 of EPA Method 2, 40 
CFR part 60, appendix A), and gas analyzer, if necessary (as described 
in EPA Method 3, 40 CFR part 60, appendix A). The temperature sensor 
ideally should be permanently attached to the pitot tube or sampling 
probe in a fixed configuration such that the top of the sensor extends 
beyond the leading edge of the probe sheath and does not touch any 
metal. Alternatively, the sensor may be attached just prior to use in 
the field. Note, however, that if the temperature sensor is attached in 
the field, the sensor must be placed in an interference-free arrangement 
with respect to the Type S pitot openings (see Figure 2-7, EPA Method 2, 
40 CFR part 60, appendix A). As a second alternative, if a difference of 
no more than 1 percent in the average velocity measurement is to be 
introduced, the temperature gauge need not be attached to the probe or 
pitot tube.

                           6.2 Sample Recovery

    6.2.1 Probe Liner: Probe nozzle and brushes; bristle brushes with 
stainless steel wire handles are required. The probe brush shall have 
extensions of stainless steel, Teflon TM, or inert material 
at least as long as the probe. The brushes shall be properly sized and 
shaped to brush out the probe liner, the probe nozzle, and the 
impingers.
    6.2.2 Wash Bottles: One wash bottle is required. Polyethylene, 
Teflon TM, or glass wash bottles may be used for sample 
recovery.
    6.2.3 Graduated Cylinder and/or Balance: A graduated cylinder or 
balance is required to measure condensed water to the nearest 1 ml or 1 
g. Graduated cylinders shall have division not 2 ml. 
Laboratory balances capable of weighing to [plusmn] 0.5 g are required.
    6.2.4 Polyethylene Storage Containers: 500 ml wide-mouth 
polyethylene bottles are required to store impinger water samples.
    6.2.5 Rubber Policeman and Funnel: A rubber policeman and funnel are 
required to aid the transfer of material into and out of containers in 
the field.

                           6.3 Sample Analysis

    6.3.1 Spectrophotometer--B&L 70, 710, 2000, etc., or equivalent; 1 
cm pathlength cuvette holder.
    6.3.2 Disposable polystyrene cuvettes, pathlengh 1 cm, volume of 
about 4.5 ml.
    6.3.3 Pipettors--Fixed-volume Oxford pipet (250 [mu]l; 500 [mu]l; 
1000 [mu]l); adjustable volume Oxford or equivalent pipettor 1-5 ml 
model, set to 2.50 ml.
    6.3.4 Pipet tips for pipettors above.
    6.3.5 Parafilm, 2 [deg] wide; cut into about 1'' squares.

                              7.0 Reagents

    7.1 High purity water: All references to water in this method refer 
to high purity water (ASTM Type I water or equivalent). The water purity 
will dictate the lower limits of formaldehyde quantification.
    7.2 Silica Gel: Silica gel shall be indicting type, 6-16 mesh. If 
the silica gel has been used previously, dry at 175 [deg]C (350 [deg]F) 
for 2 hours before using. New silica gel may be used as received. 
Alternatively, other types of desiccants (equivalent or better) may be 
used.
    7.3 Crushed Ice: Quantities ranging from 10-50 lbs may be necessary 
during a sampling run, depending upon ambient temperature. Samples which 
have been taken must be stored and shipped cold; sufficient ice for this 
purpose must be allowed.
    7.4 Quaternary ammonium compound stock solution: Prepare a stock 
solution of dodecyltrimethylammonium chloride (98 percent minimum assay, 
reagent grade) by dissolving 1.0 gram in 1000 ml water. This solution 
contains nominally 1000 [mu]g/ml quaternary ammonium compound, and is 
used as a biocide for some sources which are prone to microbial 
contamination.
    7.5 Pararosaniline: Weigh 0.16 grams pararosaniline (free base; 
assay of 95 percent or greater, C.I. 42500; Sigma P7632 has been found 
to be acceptable) into a 100 ml flask. Exercise care, since 
pararosaniline is a dye and will stain. Using a wash bottle with

[[Page 1078]]

high-purity water, rinse the walls of the flask. Add no more than 25 ml 
water. Then, carefully add 20 ml of concentrated hydrochloric acid to 
the flask. The flask will become warm after the addition of acid. Add a 
magnetic stir bar to the flask, cap, and place on a magnetic stirrer for 
approximately 4 hours. Then, add additional water so the total volume is 
100 ml. This solution is stable for several months when stored tightly 
capped at room temperature.
    7.6 Sodium sulfite: Weigh 0.10 grams anhydrous sodium sulfite into a 
100 ml flask. Dilute to the mark with high purity water. Invert 15-20 
times to mix and dissolve the sodium sulfite. This solution must be 
prepared fresh every day.
    7.7 Formaldehyde standard solution: Pipet exactly 2.70 ml of 37 
percent formaldehyde solution into a 1000 ml volumetric flask which 
contains about 500 ml of high-purity water. Dilute to the mark with 
high-purity water. This solution contains nominally 1000 [mu]g/ml of 
formaldehyde, and is used to prepare the working formaldehyde standards. 
The exact formaldehyde concentration may be determined if needed by 
suitable modification of the sodium sulfite method (Reference: J.F. 
Walker, Formaldehyde (Third Edition), 1964.). The 1000 [mu]g/ml 
formaldehyde stock solution is stable for at least a year if kept 
tightly closed, with the neck of the flask sealed with Parafilm. Store 
at room temperature.
    7.8 Working formaldehyde standards: Pipet exactly 10.0 ml of the 
1000 [mu]g/ml formaldehyde stock solution into a 100 ml volumetric flask 
which is about half full of high-purity water. Dilute to the mark with 
high-purity water, and invert 15-20 times to mix thoroughly. This 
solution contains nominally 100 [mu]g/ml formaldehyde. Prepare the 
working standards from this 100 [mu]g/ml standard solution and using the 
Oxford pipets:

                                                                flask

                                                                water)
------------------------------------------------------------------------
0.250.........................................          250          100
0.500.........................................          500          100
1.00..........................................         1000          100

3.00..........................................         1500           50
------------------------------------------------------------------------

The 100 [mu]g/ml stock solution is stable for 4 weeks if kept 
refrigerated between analyses. The working standards (0.25-3.00 [mu]g/
ml) should be prepared fresh every day, consistent with good laboratory 
practice for trace analysis. If the laboratory water is not of 
sufficient purity, it may be necessary to prepare the working standards 
every day. The laboratory must establish that the working standards are 
stable--DO NOT assume that your working standards are stable for more 
than a day unless you have verified this by actual testing for several 
series of working standards.

                          8.0 Sample Collection

    8.1 Because of the complexity of this method, field personnel should 
be trained in and experienced with the test procedures in order to 
obtain reliable results.

                       8.2 Laboratory Preparation

    8.2.1 All the components shall be maintained and calibrated 
according to the procedure described in APTD-0576, unless otherwise 
specified.
    8.2.2 Weigh several 200 to 300 g portions of silica gel in airtight 
containers to the nearest 0.5 g. Record on each container the total 
weight of the silica gel plus containers. As an alternative to 
preweighing the silica gel, it may instead be weighed directly in the 
impinger or sampling holder just prior to train assembly.

                  8.3 Preliminary Field Determinations

    8.3.1 Select the sampling site and the minimum number of sampling 
points according to EPA Method 1, 40 CFR part 60, appendix A, or other 
relevant criteria. Determine the stack pressure, temperature, and range 
of velocity heads using EPA Method 2, 40 CFR part 60, appendix A. A 
leak-check of the pitot lines according to Section 3.1 of EPA Method 2, 
40 CFR part 60, appendix A, must be performed. Determine the stack gas 
moisture content using EPA Approximation Method 4,40 CFR part 60, 
appendix A, or its alternatives to establish estimates of isokinetic 
sampling rate settings. Determine the stack gas dry molecular weight, as 
described in EPA Method 2, 40 CFR part 60, appendix A, Section 3.6. If 
integrated EPA Method 3, 40 CFR part 60, appendix A, sampling is used 
for molecular weight determination, the integrated bag sample shall be 
taken simultaneously with, and for the same total length of time as, the 
sample run.
    8.3.2 Select a nozzle size based on the range of velocity heads so 
that it is not necessary to change the nozzle size in order to maintain 
isokinetic sampling rates below 28 l/min (1.0 cfm). During the run do 
not change the nozzle. Ensure that the proper differential pressure 
gauge is chosen for the range of velocity heads encountered (see Section 
2.2 of EPA Method 2, 40 CFR part 60, appendix A).
    8.3.3 Select a suitable probe liner and probe length so that all 
traverse points can be sampled. For large stacks, to reduce the length 
of the probe, consider sampling from opposite sides of the stack.
    8.3.4 A minimum of 30 cu ft of sample volume is suggested for 
emission sources with stack concentrations not greater than 23,000,000 
ppbv. Additional sample volume

[[Page 1079]]

shall be collected as necessitated by the capacity of the water reagent 
and analytical detection limit constraint. Reduced sample volume may be 
collected as long as the final concentration of formaldehyde in the 
stack sample is greater than 10 (ten) times the detection limit.
    8.3.5 Determine the total length of sampling time needed to obtain 
the identified minimum volume by comparing the anticipated average 
sampling rate with the volume requirement. Allocate the same time to all 
traverse points defined by EPA Method 1, 40 CFR part 60, appendix A. To 
avoid timekeeping errors, the length of time sampled at each traverse 
point should be an integer or an integer plus 0.5 min.
    8.3.6 In some circumstances (e.g., batch cycles) it may be necessary 
to sample for shorter times at the traverse points and to obtain smaller 
gas-volume samples. In these cases, careful documentation must be 
maintained in order to allow accurate calculations of concentrations.

                   8.4 Preparation of Collection Train

    8.4.1 During preparation and assembly of the sampling train, keep 
all openings where contamination can occur covered with 
TeflonTM film or aluminum foil until just prior to assembly 
or until sampling is about to begin.
    8.4.2 Place 100 ml of water in each of the first two impingers, and 
leave the third impinger empty. If additional capacity is required for 
high expected concentrations of formaldehyde in the stack gas, 200 ml of 
water per impinger may be used or additional impingers may be used for 
sampling. Transfer approximately 200 to 300 g of pre-weighed silica gel 
from its container to the fourth impinger. Care should be taken to 
ensure that the silica gel is not entrained and carried out from the 
impinger during sampling. Place the silica gel container in a clean 
place for later use in the sample recovery. Alternatively, the weight of 
the silica gel plus impinger may be determined to the nearest 0.5 g and 
recorded.
    8.4.3 With a glass or quartz liner, install the selected nozzle 
using a Viton-A O-ring when stack temperatures are <260 [deg]C (500 
[deg]F) and a woven glass-fiber gasket when temperatures are higher. See 
APTD-0576 for details. Other connection systems utilizing either 316 
stainless steel or TeflonTM ferrules may be used. Mark the 
probe with heat-resistant tape or by some other method to denote the 
proper distance into the stack or duct for each sampling point.
    8.4.4 Assemble the train as shown in Figure 1. During assembly, a 
very light coating of silicone grease may be used on ground-glass joints 
of the impingers, but the silicone grease should be limited to the outer 
portion (see APTD-0576) of the ground-glass joints to minimize silicone 
grease contamination. If necessary, TeflonTM tape may be used 
to seal leaks. Connect all temperature sensors to an appropriate 
potentiometer/display unit. Check all temperature sensors at ambient 
temperatures.
    8.4.5 Place crushed ice all around the impingers.
    8.4.6 Turn on and set the probe heating system at the desired 
operating temperature. Allow time for the temperature to stabilize.

                        8.5 Leak-Check Procedures

    8.5.1 Pre-test Leak-check: Recommended, but not required. If the 
tester elects to conduct the pre-test leak-check, the following 
procedure shall be used.
    8.5.1.1 After the sampling train has been assembled, turn on and set 
probe heating system at the desired operating temperature. Allow time 
for the temperature to stabilize. If a Viton-a O-ring or other leak-free 
connection is used in assembling the probe nozzle to the probe liner, 
leak-check the train at the sampling site by plugging the nozzle and 
pulling a 381 mm Hg (15 in Hg) vacuum.

    Note: A lower vacuum may be used, provided that the lower vacuum is 
not exceeded during the test.

    If a woven glass fiber gasket is used, do not connect the probe to 
the train during the leak-check. Instead, leak-check the train by first 
attaching a carbon-filled leak-check impinger to the inlet and then 
plugging the inlet and pulling a 381 mm Hg (15 in Hg) vacuum. (A lower 
vacuum may be used if this lower vacuum is not exceeded during the 
test.) Next connect the probe to the train and leak-check at about 25 mm 
Hg (1 in Hg) vacuum. Alternatively, leak-check the probe with the rest 
of the sampling train in one step at 381 mm Hg (15 in Hg) vacuum. 
Leakage rates in excess of (a) 4 percent of the average sampling rate or 
(b) 0.00057 m3/min (0.02 cfm), whichever is less, are 
unacceptable.
    8.5.1.2 The following leak-check instructions for the sampling train 
described in APTD-0576 and APTD-0581 may be helpful. Start the pump with 
the fine-adjust valve fully open and coarse-valve completely closed. 
Partially open the coarse-adjust valve and slowly close the fine-adjust 
valve until the desired vacuum is reached. Do not reverse direction of 
the fine-adjust valve, as liquid will back up into the train. If the 
desired vacuum is exceeded, either perform the leak-check at this higher 
vacuum or end the leak-check, as described below, and start over.
    8.5.1.3 When the leak-check is completed, first slowly remove the 
plug from the inlet to the probe. When the vacuum drops to 127 mm (5 in) 
Hg or less, immediately close the coarse-adjust valve. Switch off the 
pumping system and reopen the fine-adjust valve. Do not reopen the fine-
adjust valve until the

[[Page 1080]]

coarse-adjust valve has been closed to prevent the liquid in the 
impingers from being forced backward in the sampling line and silica gel 
from being entrained backward into the third impinger.
    8.5.2 Leak-checks During Sampling Run:
    8.5.2.1 If, during the sampling run, a component change (e.g., 
impinger) becomes necessary, a leak-check shall be conducted immediately 
after the interruption of sampling and before the change is made. The 
leak-check shall be done according to the procedure described in Section 
10.3.3, except that it shall be done at a vacuum greater than or equal 
to the maximum value recorded up to that point in the test. If the 
leakage rate is found to be no greater than 0.0057 m3/min 
(0.02 cfm) or 4 percent of the average sampling rate (whichever is 
less), the results are acceptable. If a higher leakage rate is obtained, 
the tester must void the sampling run.

    Note: Any correction of the sample volume by calculation reduces the 
integrity of the pollutant concentration data generated and must be 
avoided.

    8.5.2.2 Immediately after component changes, leak-checks are 
optional. If performed, the procedure described in section 8.5.1.1 shall 
be used.
    8.5.3 Post-test Leak-check:
    8.5.3.1 A leak-check is mandatory at the conclusion of each sampling 
run. The leak-check shall be done with the same procedures as the pre-
test leak-check, except that the post-test leak-check shall be conducted 
at a vacuum greater than or equal to the maximum value reached during 
the sampling run. If the leakage rate is found to be no greater than 
0.00057 m3/min (0.02 cfm) or 4 percent of the average 
sampling rate (whichever is less), the results are acceptable. If, 
however, a higher leakage rate is obtained, the tester shall record the 
leakage rate and void the sampling run.

                      8.6 Sampling Train Operation

    8.6.1 During the sampling run, maintain an isokinetic sampling rate 
to within 10 percent of true isokinetic, below 28 l/min (1.0 cfm). 
Maintain a temperature around the probe of 120 [deg]C [plusmn] 14 [deg]C 
(248 [deg] [plusmn] 25 [deg]F).
    8.6.2 For each run, record the data on a data sheet such as the one 
shown in Figure 2. Be sure to record the initial dry-gas meter reading. 
Record the dry-gas meter readings at the beginning and end of each 
sampling time increment, when changes in flow rates are made, before and 
after each leak-check, and when sampling is halted. Take other readings 
required by Figure 2 at least once at each sample point during each time 
increment and additional readings when significant adjustments (20 
percent variation in velocity head readings) necessitate additional 
adjustments in flow rate. Level and zero the manometer. Because the 
manometer level and zero may drift due to vibrations and temperature 
changes, make periodic checks during the traverse.

    8.6.3 Clean the stack access ports prior to the test run to 
eliminate the chance of sampling deposited material. To begin sampling, 
remove the nozzle cap, verify that the probe heating system are at the 
specified temperature, and verify that the pitot tube and probe are 
properly positioned. Position the nozzle at the first traverse point, 
with the tip pointing directly into the gas stream. Immediately start 
the pump and adjust the flow to isokinetic conditions. Nomographs, which 
aid in the rapid adjustment of the isokinetic sampling rate without 
excessive computations, are available. These nomographs are designed for 
use when the Type S pitot tube coefficient is 0.84 [plusmn] 0.02 and the 
stack gas equivalent density (dry molecular weight) is equal to 29 
[plusmn] 4. APTD-0576 details the procedure for using the nomographs. If 
the stack gas molecular weight and the pitot tube coefficient are 
outside the above ranges, do not use the nomographs unless appropriate 
steps are taken to compensate for the deviations.
    8.6.4 When the stack is under significant negative pressure 
(equivalent to the height of the impinger stem), take care to close the 
coarse-adjust valve before inserting the probe into the stack in order 
to prevent liquid from backing up through the train. If necessary, a low 
vacuum on the train may have to be started prior to entering the stack.
    8.6.5 When the probe is in position, block off the openings around 
the probe and stack access port to prevent unrepresentative dilution of 
the gas stream.
    8.6.6 Traverse the stack cross section, as required by EPA Method 1, 
40 CFR part 60, appendix A, being careful not to bump the probe nozzle 
into the stack walls when sampling near the walls or when removing or 
inserting the probe through the access port, in order to minimize the 
chance of extracting deposited material.
    8.6.7 During the test run, make periodic adjustments to keep the 
temperature around the probe at the proper levels. Add more ice and, if 
necessary, salt, to maintain a temperature of <20 [deg]C (68 [deg]F) at 
the silica gel outlet.
    8.6.8 A single train shall be used for the entire sampling run, 
except in cases where simultaneous sampling is required in two or more 
separate ducts or at two or more different locations within the same 
duct, or in cases where equipment failure necessitates a change of 
trains. An additional train or trains may also be used for sampling when 
the capacity of a single train is exceeded.
    8.6.9 When two or more trains are used, separate analyses of 
components from each train shall be performed. If multiple trains have 
been used because the capacity of a single train would be exceeded, 
first impingers from each train may be combined, and second impingers 
from each train may be combined.
    8.6.10 At the end of the sampling run, turn off the coarse-adjust 
valve, remove the probe and nozzle from the stack, turn off the pump, 
record the final dry gas meter reading, and conduct a post-test leak-
check. Also, check the pitot lines as described in EPA Method 2, 40 CFR 
part 60, appendix A. The lines must pass this leak-check in order to 
validate the velocity-head data.
    8.6.11 Calculate percent isokineticity (see Method 2) to determine 
whether the run was valid or another test should be made.

                  8.7 Sample Preservation and Handling

    8.7.1 Samples from most sources applicable to this method have 
acceptable holding times using normal handling practices (shipping 
samples iced, storing in refrigerator at 2 [deg]C until analysis). 
However, forming section stacks and other sources using waste water 
sprays may be subject to microbial contamination. For these sources, a 
biocide (quaternary ammonium compound solution) may be added to 
collected samples to improve sample stability and method ruggedness.
    8.7.2 Sample holding time: Samples should be analyzed within 14 days 
of collection. Samples must be refrigerated/kept cold

[[Page 1083]]

for the entire period preceding analysis. After the samples have been 
brought to room temperature for analysis, any analyses needed should be 
performed on the same day. Repeated cycles of warming the samples to 
room temperature/refrigerating/rewarming, then analyzing again, etc., 
have not been investigated in depth to evaluate if analyte levels remain 
stable for all sources.
    8.7.3 Additional studies will be performed to evaluate whether 
longer sample holding times are feasible for this method.

                           8.8 Sample Recovery

    8.8.1 Preparation:
    8.8.1.1 Proper cleanup procedure begins as soon as the probe is 
removed from the stack at the end of the sampling period. Allow the 
probe to cool. When the probe can be handled safely, wipe off all 
external particulate matter near the tip of the probe nozzle and place a 
cap over the tip to prevent losing or gaining particulate matter. Do not 
cap the probe tightly while the sampling train is cooling because a 
vacuum will be created, drawing liquid from the impingers back through 
the sampling train.
    8.8.1.2 Before moving the sampling train to the cleanup site, remove 
the probe from the sampling train and cap the open outlet, being careful 
not to lose any condensate that might be present. Remove the umbilical 
cord from the last impinger and cap the impinger. If a flexible line is 
used, let any condensed water or liquid drain into the impingers. Cap 
off any open impinger inlets and outlets. Ground glass stoppers, Teflon 
TM caps, or caps of other inert materials may be used to seal 
all openings.
    8.8.1.3 Transfer the probe and impinger assembly to an area that is 
clean and protected from wind so that the chances of contaminating or 
losing the sample are minimized.
    8.8.1.4 Inspect the train before and during disassembly, and note 
any abnormal conditions.
    8.8.1.5 Save a portion of the washing solution (high purity water) 
used for cleanup as a blank.
    8.8.2 Sample Containers:
    8.8.2.1 Container 1: Probe and Impinger Catches. Using a graduated 
cylinder, measure to the nearest ml, and record the volume of the 
solution in the first three impingers. Alternatively, the solution may 
be weighed to the nearest 0.5 g. Include any condensate in the probe in 
this determination. Transfer the combined impinger solution from the 
graduated cylinder into the polyethylene bottle. Taking care that dust 
on the outside of the probe or other exterior surfaces does not get into 
the sample, clean all surfaces to which the sample is exposed (including 
the probe nozzle, probe fitting, probe liner, first three impingers, and 
impinger connectors) with water. Use less than 400 ml for the entire 
waste (250 ml would be better, if possible). Add the rinse water to the 
sample container.
    8.8.2.1.1 Carefully remove the probe nozzle and rinse the inside 
surface with water from a wash bottle. Brush with a bristle brush and 
rinse until the rinse shows no visible particles, after which make a 
final rinse of the inside surface. Brush and rinse the inside parts of 
the Swagelok (or equivalent) fitting with water in a similar way.
    8.8.2.1.2 Rinse the probe liner with water. While squirting the 
water into the upper end of the probe, tilt and rotate the probe so that 
all inside surfaces will be wetted with water. Let the water drain from 
the lower end into the sample container. The tester may use a funnel 
(glass or polyethylene) to aid in transferring the liquid washes to the 
container. Follow the rinse with a bristle brush. Hold the probe in an 
inclined position, and squirt water into the upper end as the probe 
brush is being pushed with a twisting action through the probe. Hold the 
sample container underneath the lower end of the probe, and catch any 
water and particulate matter that is brushed from the probe. Run the 
brush through the probe three times or more. Rinse the brush with water 
and quantitatively collect these washings in the sample container. After 
the brushing, make a final rinse of the probe as describe above.

    Note: Two people should clean the probe in order to minimize sample 
losses. Between sampling runs, brushes must be kept clean and free from 
contamination.

    8.8.2.1.3 Rinse the inside surface of each of the first three 
impingers (and connecting tubing) three separate times. Use a small 
portion of water for each rinse, and brush each surface to which the 
sample is exposed with a bristle brush to ensure recovery of fine 
particulate matter. Make a final rinse of each surface and of the brush, 
using water.
    8.8.2.1.4 After all water washing and particulate matter have been 
collected in the sample container, tighten the lid so the sample will 
not leak out when the container is shipped to the laboratory. Mark the 
height of the fluid level to determine whether leakage occurs during 
transport. Label the container clearly to identify its contents.
    8.8.2.1.5 If the first two impingers are to be analyzed separately 
to check for breakthrough, separate the contents and rinses of the two 
impingers into individual containers. Care must be taken to avoid 
physical carryover from the first impinger to the second. Any physical 
carryover of collected moisture into the second impinger will invalidate 
a breakthrough assessment.
    8.8.2.2 Container 2: Sample Blank. Prepare a blank by using a 
polyethylene container and adding a volume of water equal to the total 
volume in Container 1. Process the blank in the same manner as Container 
1.

[[Page 1084]]

    8.8.2.3 Container 3: Silica Gel. Note the color of the indicating 
silica gel to determine whether it has been completely spent and make a 
notation of its condition. The impinger containing the silica gel may be 
used as a sample transport container with both ends sealed with tightly 
fitting caps or plugs. Ground-glass stoppers or TeflonTM caps 
maybe used. The silica gel impinger should then be labeled, covered with 
aluminum foil, and packaged on ice for transport to the laboratory. If 
the silica gel is removed from the impinger, the tester may use a funnel 
to pour the silica gel and a rubber policeman to remove the silica gel 
from the impinger. It is not necessary to remove the small amount of 
dust particles that may adhere to the impinger wall and are difficult to 
remove. Since the gain in weight is to be used for moisture 
calculations, do not use water or other liquids to transfer the silica 
gel. If a balance is available in the field, the spent silica gel (or 
silica gel plus impinger) may be weighed to the nearest 0.5 g.
    8.8.2.4 Sample containers should be placed in a cooler, cooled by 
(although not in contact with) ice. Putting sample bottles in Zip-
LockTM bags can aid in maintaining the integrity of the 
sample labels. Sample containers should be placed vertically to avoid 
leakage during shipment. Samples should be cooled during shipment so 
they will be received cold at the laboratory. It is critical that 
samples be chilled immediately after recovery. If the source is 
susceptible to microbial contamination from wash water (e.g. forming 
section stack), add biocide as directed in section 8.2.5.
    8.8.2.5 A quaternary ammonium compound can be used as a biocide to 
stabilize samples against microbial degradation following collection. 
Using the stock quaternary ammonium compound (QAC) solution; add 2.5 ml 
QAC solution for every 100 ml of recovered sample volume (estimate of 
volume is satisfactory) immediately after collection. The total volume 
of QAC solution must be accurately known and recorded, to correct for 
any dilution caused by the QAC solution addition.
    8.8.3 Sample Preparation for Analysis 8.8.3.1 The sample should be 
refrigerated if the analysis will not be performed on the day of 
sampling. Allow the sample to warm at room temperature for about two 
hours (if it has been refrigerated) prior to analyzing.
    8.8.3.2 Analyze the sample by the pararosaniline method, as 
described in Section 11. If the color-developed sample has an absorbance 
above the highest standard, a suitable dilution in high purity water 
should be prepared and analyzed.

                           9.0 Quality Control

    9.1 Sampling: See EPA Manual 600/4-77-02b for Method 5 quality 
control.
    9.2 Analysis: The quality assurance program required for this method 
includes the analysis of the field and method blanks, and procedure 
validations. The positive identification and quantitation of 
formaldehyde are dependent on the integrity of the samples received and 
the precision and accuracy of the analytical methodology. Quality 
assurance procedures for this method are designed to monitor the 
performance of the analytical methodology and to provide the required 
information to take corrective action if problems are observed in 
laboratory operations or in field sampling activities.
    9.2.1 Field Blanks: Field blanks must be submitted with the samples 
collected at each sampling site. The field blanks include the sample 
bottles containing aliquots of sample recover water, and water reagent. 
At a minimum, one complete sampling train will be assembled in the field 
staging area, taken to the sampling area, and leak-checked at the 
beginning and end of the testing (or for the same total number of times 
as the actual sampling train). The probe of the blank train must be 
heated during the sample test. The train will be recovered as if it were 
an actual test sample. No gaseous sample will be passed through the 
blank sampling train.
    9.2.2 Blank Correction: The field blank formaldehyde concentrations 
will be subtracted from the appropriate sample formaldehyde 
concentrations. Blank formaldehyde concentrations above 0.25 [mu]g/ml 
should be considered suspect, and subtraction from the sample 
formaldehyde concentrations should be performed in a manner acceptable 
to the Administrator.
    9.2.3 Method Blanks: A method blank must be prepared for each set of 
analytical operations, to evaluate contamination and artifacts that can 
be derived from glassware, reagents, and sample handling in the 
laboratory.

                             10 Calibration

    10.1 Probe Nozzle: Probe nozzles shall be calibrated before their 
initial use in the field. Using a micrometer, measure the inside 
diameter of the nozzle to the nearest 0.025 mm (0.001 in). Make 
measurements at three separate places across the diameter and obtain the 
average of the measurements. The difference between the high and low 
numbers shall not exceed 0.1 mm (0.004 in). When the nozzle becomes 
nicked or corroded, it shall be repaired and calibrated, or replaced 
with a calibrated nozzle before use. Each nozzle must be permanently and 
uniquely identified.
    10.2 Pitot Tube: The Type S pitot tube assembly shall be calibrated 
according to the procedure outlined in Section 4 of EPA Method 2, or 
assigned a nominal coefficient of 0.84 if it is not visibly nicked or 
corroded and if it meets design and intercomponent spacing 
specifications.

[[Page 1085]]

                          10.3 Metering System

    10.3.1 Before its initial use in the field, the metering system 
shall be calibrated according to the procedure outlined in APTD-0576. 
Instead of physically adjusting the dry-gas meter dial readings to 
correspond to the wet-test meter readings, calibration factors may be 
used to correct the gas meter dial readings mathematically to the proper 
values. Before calibrating the metering system, it is suggested that a 
leak-check be conducted. For metering systems having diaphragm pumps, 
the normal leak-check procedure will not delete leakages with the pump. 
For these cases, the following leak-check procedure will apply: Make a 
ten-minute calibration run at 0.00057 m3/min (0.02 cfm). At 
the end of the run, take the difference of the measured wet-test and 
dry-gas meter volumes and divide the difference by 10 to get the leak 
rate. The leak rate should not exceed 0.00057 m3/min (0.02 
cfm).
    10.3.2 After each field use, check the calibration of the metering 
system by performing three calibration runs at a single intermediate 
orifice setting (based on the previous field test). Set the vacuum at 
the maximum value reached during the test series. To adjust the vacuum, 
insert a valve between the wet-test meter and the inlet of the metering 
system. Calculate the average value of the calibration factor. If the 
calibration has changed by more than 5 percent, recalibrate the meter 
over the full range of orifice settings, as outlined in APTD-0576.
    10.3.3 Leak-check of metering system: The portion of the sampling 
train from the pump to the orifice meter (see Figure 1) should be leak-
checked prior to initial use and after each shipment. Leakage after the 
pump will result in less volume being recorded than is actually sampled. 
Use the following procedure: Close the main valve on the meter box. 
Insert a one-hole rubber stopper with rubber tubing attached into the 
orifice exhaust pipe. Disconnect and vent the low side of the orifice 
manometer. Close off the low side orifice tap. Pressurize the system to 
13-18 cm (5-7 in) water column by blowing into the rubber tubing. Pinch 
off the tubing and observe the manometer for 1 min. A loss of pressure 
on the manometer indicates a leak in the meter box. Leaks must be 
corrected.

    Note: If the dry-gas meter coefficient values obtained before and 
after a test series differ by 5 percent, either the test 
series must be voided or calculations for test series must be performed 
using whichever meter coefficient value (i.e., before or after) gives 
the lower value of total sample volume.

    10.4 Probe Heater: The probe heating system must be calibrated 
before its initial use in the field according to the procedure outlined 
in APTD-0576. Probes constructed according to APTD-0581 need not be 
calibrated if the calibration curves in APTD-0576 are used.
    10.5 Temperature gauges: Use the procedure in section 4.3 of USEPA 
Method 2 to calibrate in-stack temperature gauges. Dial thermometers 
such as are used for the dry gas meter and condenser outlet, shall be 
calibrated against mercury-in-glass thermometers.
    10.6 Barometer: Adjust the barometer initially and before each test 
series to agree to within [plusmn]2.5 mm Hg (0.1 in Hg) of the mercury 
barometer. Alternately, if a National Weather Service Station (NWSS) is 
located at the same altitude above sea level as the test site, the 
barometric pressure reported by the NWSS may be used.
    10.7 Balance: Calibrate the balance before each test series, using 
Class S standard weights. The weights must be within [plusmn]0.5 percent 
of the standards, or the balance must be adjusted to meet these limits.

                      11.0 Procedure for Analysis.

    The working formaldehyde standards (0.25, 0.50, 1.0, 2.0, and 3.0 
[mu]g/ml) are analyzed and a calibration curve is calculated for each 
day's analysis. The standards should be analyzed first to ensure that 
the method is working properly prior to analyzing the samples. In 
addition, a sample of the high-purity water should also be analyzed and 
used as a ``0'' formaldehyde standard.
    The procedure for analysis of samples and standards is identical: 
Using the pipet set to 2.50 ml, pipet 2.50 ml of the solution to be 
analyzed into a polystyrene cuvette. Using the 250 [mu]l pipet, pipet 
250 [mu]l of the pararosaniline reagent solution into the cuvette. Seal 
the top of the cuvette with a Parafilm square and shake at least 30 
seconds to ensure the solution in the cuvette is well-mixed. Peel back a 
corner of the Parafilm so the next reagent can be added. Using the 250 
[mu]l pipet, pipet 250 [mu]l of the sodium sulfite reagent solution into 
the cuvette. Reseal the cuvette with the Parafilm, and again shake for 
about 30 seconds to mix the solution in the cuvette. Record the time of 
addition of the sodium sulfite and let the color develop at room 
temperature for 60 minutes. Set the spectrophotometer to 570 nm and set 
to read in Absorbance Units. The spectrophotometer should be equipped 
with a holder for the 1-cm pathlength cuvettes. Place cuvette(s) 
containing high-purity water in the spectrophotometer and adjust to read 
0.000 AU.
    After the 60 minutes color development period, read the standard and 
samples in the spectrophotometer. Record the absorbance reading for each 
cuvette. The calibration curve is calculated by linear regression, with 
the formaldehyde concentration as the ``x'' coordinate of the pair, and 
the absorbance reading as the ``y'' coordinate. The procedure

[[Page 1086]]

is very reproducible, and typically will yield values similar to these 
for the calibration curve:

Correlation Coefficient: 0.9999
Slope: 0.50
Y-Intercept: 0.090

The formaldehyde concentration of the samples can be found by using the 
trend-line feature of the calculator or computer program used for the 
linear regression. For example, the TI-55 calculators use the ``X'' key 
(this gives the predicted formaldehyde concentration for the value of 
the absorbance you key in for the sample). Multiply the formaldehyde 
concentration from the sample by the dilution factor, if any, for the 
sample to give the formaldehyde concentration of the original, 
undiluted, sample (units will be micrograms/ml).

               11.1 Notes on the Pararosaniline Procedure

    11.1.1 The pararosaniline method is temperature-sensitive. However, 
the small fluctuations typical of a laboratory will not significantly 
affect the results.
    11.1.2 The calibration curve is linear to beyond 4 ``[mu]g/ml'' 
formaldehyde, however, a research-grade spectrophotometer is required to 
reproducibly read the high absorbance values. Consult your instrument 
manual to evaluate the capability of the spectrophotometer.
    11.1.3 The quality of the laboratory water used to prepare standards 
and make dilutions is critical. It is important that the cautions given 
in the Reagents section be observed. This procedure allows quantitation 
of formaldehyde at very low levels, and thus it is imperative to avoid 
contamination from other sources of formaldehyde and to exercise the 
degree of care required for trace analyses.
    11.1.4 The analyst should become familiar with the operation of the 
Oxford or equivalent pipettors before using them for an analysis. Follow 
the instructions of the manufacturer; one can pipet water into a tared 
container on any analytical balance to check pipet accuracy and 
precision. This will also establish if the proper technique is being 
used. Always use a new tip for each pipetting operation.
    11.1.5 This procedure follows the recommendations of ASTM Standard 
Guide D 3614, reading all solutions versus water in the reference cell. 
This allows the absorbance of the blank to be tracked on a daily basis. 
Refer to ASTM D 3614 for more information.

                            12.0 Calculations

    Carry out calculations, retaining at least one extra decimal figure 
beyond that of the acquired data. Round off figures after final 
calculations.

                 12.1 Calculations of Total Formaldehyde

    12.1.1 To determine the total formaldehyde in mg, use the following 
equation if biocide was not used:
    Total mg formaldehyde=
    [GRAPHIC] [TIFF OMITTED] TR14JN99.043
    
Where:
    Cd = measured conc. formaldehyde, [mu]g/ml
V = total volume of stack sample, ml
DF = dilution factor

    12.1.2 To determine the total formaldehyde in mg, use the following 
equation if biocide was used:
    Total mg formaldehyde=
    [GRAPHIC] [TIFF OMITTED] TR14JN99.044
    
Where:

Cd = measured conc. formaldehyde, [mu]g/ml
V = total volume of stack sample, ml
B = total volume of biocide added to sample, ml
DF = dilution factor

    12.2 Formaldehyde concentration (mg/m3) in stack gas. 
Determine the formaldehyde concentration (mg/m3) in the stack 
gas using the following equation: Formaldehyde concentration (mg/
m3) =
[GRAPHIC] [TIFF OMITTED] TR14JN99.045

Where:

K = 35.31 cu ft/m3 for Vm(std) in English units, 
          or
K = 1.00 m3/m3 for Vm(std) in metric 
          units
Vm(std) = volume of gas sample measured by a dry gas meter, 
          corrected to standard conditions, dscm (dscf)

    12.3 Average dry gas meter temperature and average orifice pressure 
drop are obtained from the data sheet.
    12.4 Dry Gas Volume: Calculate Vm(std) and adjust for 
leakage, if necessary, using the equation in Section 6.3 of EPA Method 
5, 40 CFR part 60, appendix A.
    12.5 Volume of Water Vapor and Moisture Content: Calculated the 
volume of water vapor and moisture content from equations 5-2 and 5-3 of 
EPA Method 5.

                         13.0 Method Performance

    The precision of this method is estimated to be better than 
[plusmn]5 percent, expressed as [plusmn] the percent relative standard 
deviation.

Method 318--Extractive FTIR Method for the Measurement of Emissions From 
             the Mineral Wool and Wool Fiberglass Industries

                        1.0 Scope and Application

    This method has been validated and approved for mineral wool and 
wool fiberglass sources. This method may not be applied to other source 
categories without validation and approval by the Administrator 
according to the procedures in Test Method 301, 40 CFR part 63, appendix 
A. For sources seeking to apply FTIR to other source categories, Test 
Method 320 (40 CFR part 63, appendix A) may be utilized.
    1.1 Scope. The analytes measured by this method and their CAS 
numbers are:

Carbon Monoxide 630-08-0
Carbonyl Sulfide 463-58-1
Formaldehyde 50-00-0
Methanol 1455-13-6
Phenol 108-95-2

                            1.2 Applicability

    1.2.1 This method is applicable for the determination of 
formaldehyde, phenol, methanol, carbonyl sulfide (COS) and carbon 
monoxide (CO) concentrations in controlled and uncontrolled emissions 
from manufacturing processes using phenolic resins. The compounds are 
analyzed in the mid-infrared spectral region (about 400 to 4000 cm-1 or 
25 to 2.5 [mu]m). Suggested analytical regions are given below (Table 
1). Slight deviations from these recommended regions may be necessary 
due to variations in moisture content and ammonia concentration from 
source to source.

                                       Table 1--Example Analytical Regions

----------------------------------------------------------------------------------------------------------------
a Suggested analytical regions assume about 15 percent moisture and CO2, and that COS and CO have about the same
  absorbance (in the range of 10 to 50 ppm). If CO and COS are hundreds of ppm or higher, then CO2 and moisture
  interference is reduced. If CO or COS is present at high concentration and the other at low concentration,
  then a shorter cell pathlength may be necessary to measure the high concentration component.

1.2.2 This method does not apply when: (a) Polymerization of 
formaldehyde occurs, (b) moisture condenses in either the sampling 
system or the instrumentation, and (c) when moisture content of the gas 
stream is so high relative to the analyte concentrations that it causes 
severe spectral interference.

                    1.3 Method Range and Sensitivity

    1.3.1 The analytical range is a function of instrumental design and 
composition of the gas stream. Theoretical detection limits depend, in 
part, on (a) the absorption coefficient of the compound in the 
analytical frequency region, (b) the spectral resolution, (c) 
interferometer sampling time, (d) detector sensitivity and response, and 
(e) absorption pathlength.
    1.3.2 Practically, there is no upper limit to the range. The 
practical lower detection limit is usually higher than the theoretical 
value, and depends on (a) moisture content of the flue gas, (b) presence 
of interferants, and (c) losses in the sampling system. In general, a 22 
meter pathlength cell in a suitable sampling system can achieve 
practical detection limits of 1.5 ppm for three compounds (formaldehyde, 
phenol, and methanol) at moisture levels up to 15 percent by volume. 
Sources with uncontrolled emissions of CO and COS may require a 4 meter 
pathlength cell due to high concentration levels. For these two 
compounds, make sure absorbance of highest concentration component is 
<1.0.

                       1.4 Data Quality Objectives

1.4.1 In designing or configuring the system, the analyst first sets the 
data quality objectives, i.e., the desired lower detection limit 
(DLi) and the desired analytical uncertainty (AUi) 
for each compound. The instrumental parameters (factors b, c, d, and e 
in Section 1.3.1) are then chosen to meet these requirements, using 
Appendix D of the FTIR Protocol.
1.4.2 Data quality for each application is determined, in part, by 
measuring the RMS (Root Mean Square) noise level in each analytical 
spectral region (Appendix C of the FTIR Protocol). The RMS noise is 
defined as

[[Page 1088]]

the RMSD (Root Mean Square Deviation) of the absorbance values in an 
analytical region from the mean absorbance value of the region. Appendix 
D of the FTIR Protocol defines the MAUim (minimum analyte 
uncertainty of the ith analyte in the mth 
analytical region). The MAU is the minimum analyte concentration for 
which the analytical uncertainty limit (AUi) can be 
maintained: if the measured analyte concentration is less than 
MAUi, then data quality is unacceptable. Table 2 gives some 
example DL and AU values along with calculated areas and MAU values 
using the protocol procedures.

                          2.0 Summary of Method

                              2.1 Principle

    2.1.1 Molecules are composed of chemically bonded atoms, which are 
in constant motion. The atomic motions result in bond deformations (bond 
stretching and bond-angle bending). The number of fundamental (or 
independent) vibrational motions depends on the number of atoms (N) in 
the molecule. At typical testing temperatures, most molecules are in the 
ground-state vibrational state for most of their fundamental vibrational 
motions. A molecule can undergo a transition from its ground state (for 
a particular vibration) to the first excited state by absorbing a 
quantum of light at a frequency characteristic of the molecule and the 
molecular motion. Molecules also undergo rotational transitions by 
absorbing energies in the far-infrared or microwave spectral regions. 
Rotational transition absorbencies are superimposed on the vibrational 
absorbencies to give a characteristic shape to each rotational-
vibrational absorbance ``band.''
    2.1.2 Most molecules exhibit more than one absorbance band in 
several frequency regions to produce an infrared spectrum (a 
characteristic pattern of bands or a ``fingerprint'') that is unique to 
each molecule. The infrared spectrum of a molecule depends on its 
structure (bond lengths, bond angles, bond strengths, and atomic 
masses). Even small differences in structure can produce significantly 
different spectra.
    2.1.3 Spectral band intensities vary with the concentration of the 
absorbing compound. Within constraints, the relationship between 
absorbance and sample concentration is linear. Sample spectra are 
compared to reference spectra to determine the species and their 
concentrations.

                        2.2 Sampling and Analysis

    2.2.1 Flue gas is continuously extracted from the source, and the 
gas or a portion of the gas is conveyed to the FTIR gas cell, where a 
spectrum of the flue gas is recorded. Absorbance band intensities are 
related to sample concentrations by Beer's Law.
Where:
[GRAPHIC] [TIFF OMITTED] TR14JN99.046

A = absorbance of the ith component at the given 
          frequency, [nu].
a = absorption coefficient of the ith component at the 
          frequency, [nu].
b = path length of the cell.
c = concentration of the ith compound in the sample at 
          frequency [nu].

    2.2.2 After identifying a compound from the infrared spectrum, its 
concentration is determined by comparing band intensities in the sample 
spectrum to band intensities in ``reference spectra'' of the 
formaldehyde, phenol, methanol, COS and CO. These reference spectra are 
available in a permanent soft copy from the EPA spectral library on the 
EMTIC bulletin board. The source may also prepare reference spectra 
according to Section 4.5 of the FTIR Protocol.

    Note: Reference spectra not prepared according to the FTIR Protocol 
are not acceptable for use in this test method. Documentation detailing 
the FTIR Protocol steps used

[[Page 1089]]

in preparing any non-EPA reference spectra shall be included in each 
test report submitted by the source.

    2.3 Operator Requirements. The analyst must have some knowledge of 
source sampling and of infrared spectral patterns to operate the 
sampling system and to choose a suitable instrument configuration. The 
analyst should also understand FTIR instrument operation well enough to 
choose an instrument configuration consistent with the data quality 
objectives.

                             3.0 Definitions

    See Appendix A of the FTIR Protocol.

                            4.0 Interferences

    4.1 Analytical (or Spectral) Interferences. Water vapor. High 
concentrations of ammonia (hundreds of ppm) may interfere with the 
analysis of low concentrations of methanol (1 to 5 ppm). For CO, carbon 
dioxide and water may be interferants. In cases where COS levels are low 
relative to CO levels, CO and water may be interferants.
    4.2 Sampling System Interferences. Water, if it condenses, and 
ammonia, which reacts with formaldehyde.

                               5.0 Safety

    5.1 Formaldehyde is a suspected carcinogen; therefore, exposure to 
this compound must be limited. Proper monitoring and safety precautions 
must be practiced in any atmosphere with potentially high concentrations 
of CO.
    5.2 This method may involve sampling at locations having high 
positive or negative pressures, high temperatures, elevated heights, 
high concentrations of hazardous or toxic pollutants, or other diverse 
sampling conditions. It is the responsibility of the tester(s) to ensure 
proper safety and health practices, and to determine the applicability 
of regulatory limitations before performing this test method.

                       6.0 Equipment and Supplies

    The equipment and supplies are based on the schematic of a sampling 
train shown in Figure 1. Either the evacuated or purged sampling 
technique may be used with this sampling train. Alternatives may be 
used, provided that the data quality objectives of this method are met.
    6.1 Sampling Probe. Glass, stainless steel, or other appropriate 
material of sufficient length and physical integrity to sustain heating, 
prevent adsorption of analytes, and to reach gas sampling point.
    6.2 Particulate Filters. A glass wool plug (optional) inserted at 
the probe tip (for large particulate removal) and a filter rated at 1-
micron (e.g., BalstonTM) for fine particulate removal, placed 
immediately after the heated probe.
    6.3 Sampling Line/Heating System. Heated (maintained at 250 [plusmn] 
25 degrees F) stainless steel, TeflonTM, or other inert 
material that does not adsorb the analytes, to transport the sample to 
analytical system.
    6.4 Stainless Steel Tubing. Type 316, e.g., \3/8\ in. diameter, and 
appropriate length for heated connections.
    6.5 Gas Regulators. Appropriate for individual gas cylinders.

[[Page 1090]]

[GRAPHIC] [TIFF OMITTED] TR14JN99.052

    6.6 TeflonTM Tubing. Diameter (e.g., \3/8\ in.) and 
length suitable to connect cylinder regulators.
    6.7 Sample Pump. A leak-free pump (e.g., KNF TM), with 
by-pass valve, capable of pulling sample through entire sampling system 
at a rate of about 10 to 20 L/min. If placed before the analytical 
system, heat the pump and use a pump fabricated from materials non-
reactive to the target pollutants. If the pump is located after the 
instrument, systematically record the sample pressure in the gas cell.
    6.8 Gas Sample Manifold. A heated manifold that diverts part of the 
sample stream to the analyzer, and the rest to the by-pass discharge 
vent or other analytical instrumentation.
    6.9 Rotameter. A calibrated 0 to 20 L/min range rotameter.
    6.10 FTIR Analytical System. Spectrometer and detector, capable of 
measuring formaldehyde, phenol, methanol, COS and CO to the 
predetermined minimum detectable level. The system shall include a 
personal computer with compatible software that provides real-time 
updates of the spectral profile during sample collection and spectral 
collection.
    6.11 FTIR Cell Pump. Required for the evacuated sampling technique, 
capable of evacuating the FTIR cell volume within 2 minutes. The FTIR 
cell pump should allow the operator to obtain at least 8 sample spectra 
in 1 hour.
    6.12 Absolute Pressure Gauge. Heatable and capable of measuring 
pressure from 0 to 1000 mmHg to within [plusmn]2.5 mmHg (e.g., 
BaratronTM).
    6.13 Temperature Gauge. Capable of measuring the cell temperature to 
within [plusmn]2 [deg]C.

[[Page 1091]]

                       7.0 Reagents and Standards

    7.1 Ethylene (Calibration Transfer Standard). Obtain NIST traceable 
(or Protocol) cylinder gas.
    7.2 Nitrogen. Ultra high purity (UHP) grade.
    7.3 Reference Spectra. Obtain reference spectra for the target 
pollutants at concentrations that bracket (in ppm-meter/K) the emission 
source levels. Also, obtain reference spectra for SF6 and 
ethylene. Suitable concentrations are 0.0112 to 0.112 (ppm-meter)/K for 
SF6 and 5.61 (ppm-meter)/K or less for ethylene. The 
reference spectra shall meet the criteria for acceptance outlined in 
Section 2.2.2. The optical density (ppm-meters/K) of the reference 
spectrum must match the optical density of the sample spectrum within 
(less than) 25 percent.

            8.0 Sample Collection, Preservation, and Storage

    Sampling should be performed in the following sequence: Collect 
background, collect CTS spectrum, collect samples, collect post-test CTS 
spectrum, verify that two copies of all data were stored on separate 
computer media.
    8.1 Pretest Preparations and Evaluations. Using the procedure in 
Section 4.0 of the FTIR Protocol, determine the optimum sampling system 
configuration for sampling the target pollutants. Table 2 gives some 
example values for AU, DL, and MAU. Based on a study (Reference 1), an 
FTIR system using 1 cm-1 resolution, 22 meter path length, 
and a broad band MCT detector was suitable for meeting the requirements 
in Table 2. Other factors that must be determined are:
    a. Test requirements: AUi, CMAXi, 
DLi, OFUi, and tAN for each.
    b. Interferants: See Table 1.
    c. Sampling system: LS', Pmin, PS', 
TS', tSS, VSS; fractional error, MIL.
    d. Analytical regions: 1 through Nm, FLm, 
FCm, and FUm, plus interferants, FFUm, 
FFLm, wavenumber range FNU to FNL. See Tables 1 and 2.
    8.1.1 If necessary, sample and acquire an initial spectrum. Then 
determine the proper operational pathlength of the instrument to obtain 
non-saturated absorbances of the target analytes.
    8.1.2 Set up the sampling train as shown in Figure 1.
    8.2 Sampling System Leak-check. Leak-check from the probe tip to 
pump outlet as follows: Connect a 0- to 250-mL/min rate meter (rotameter 
or bubble meter) to the outlet of the pump. Close off the inlet to the 
probe, and note the leakage rate. The leakage rate shall be [le]200 mL/
min.
    8.3 Analytical System Leak-check.
    8.3.1 For the evacuated sample technique, close the valve to the 
FTIR cell, and evacuate the absorption cell to the minimum absolute 
pressure Pmin. Close the valve to the pump, and determine the 
change in pressure [Delta]Pv after 2 minutes.
    8.3.2 For both the evacuated sample and purging techniques, 
pressurize the system to about 100 mmHg above atmospheric pressure. 
Isolate the pump and determine the change in pressure 
[Delta]Pp after 2 minutes.
    8.3.3 Measure the barometric pressure, Pb in mmHg.
    8.3.4 Determine the percent leak volume %VL for the 
signal integration time tSS and for [Delta]Pmax, 
i.e., the larger of [Delta]Pv or [Delta]Pp, as 
follows:
[GRAPHIC] [TIFF OMITTED] TR14JN99.047

Where:

50 = 100% divided by the leak-check time of 2 minutes.

    8.3.5 Leak volumes in excess of 4 percent of the sample system 
volume VSS are unacceptable.
    8.4 Background Spectrum. Evacuate the gas cell to [le]5 mmHg, and 
fill with dry nitrogen gas to ambient pressure. Verify that no 
significant amounts of absorbing species (for example water vapor and 
CO2) are present. Collect a background spectrum, using a 
signal averaging period equal to or greater than the averaging period 
for the sample spectra. Assign a unique file name to the background 
spectrum. Store the spectra of the background interferogram and 
processed single-beam background spectrum on two separate computer media 
(one is used as the back-up). If continuous sampling will be used during 
sample collection, collect the background spectrum with nitrogen gas 
flowing through the cell at the same pressure and temperature as will be 
used during sampling.
    8.5 Pre-Test Calibration Transfer Standard. Evacuate the gas cell to 
[le]5 mmHg absolute pressure, and fill the FTIR cell to atmospheric 
pressure with the CTS gas. Or, purge the cell with 10 cell volumes of 
CTS gas. Record the spectrum. If continuous sampling will be used during 
sample collection, collect the CTS spectrum with CTS gas flowing through 
the cell at the same pressure and temperature as will be used during 
sampling.

                               8.6 Samples

    8.6.1 Evacuated Samples. Evacuate the absorbance cell to [le]5 mmHg 
absolute pressure. Fill the cell with flue gas to ambient pressure and 
record the spectrum. Before taking the next sample, evacuate the cell 
until no further evidence of absorption exists. Repeat this procedure to 
collect at least 8 separate spectra (samples) in 1 hour.
    8.6.2 Purge Sampling. Purge the FTIR cell with 10 cell volumes of 
flue gas and at least for about 10 minutes. Discontinue the gas

[[Page 1092]]

cell purge, isolate the cell, and record the sample spectrum and the 
pressure. Before taking the next sample, purge the cell with 10 cell 
volumes of flue gas.
    8.6.3 Continuous Sampling. Spectra can be collected continuously 
while the FTIR cell is being purged. The sample integration time, 
tss, the sample flow rate through the FTIR gas cell, and the 
total run time must be chosen so that the collected data consist of at 
least 10 spectra with each spectrum being of a separate cell volume of 
flue gas. More spectra can be collected over the run time and the total 
run time (and number of spectra) can be extended as well.

               8.7 Sampling QA, Data Storage and Reporting

    8.7.1 Sample integration times should be sufficient to achieve the 
required signal-to-noise ratios. Obtain an absorbance spectrum by 
filling the cell with nitrogen. Measure the RMSD in each analytical 
region in this absorbance spectrum. Verify that the number of scans is 
sufficient to achieve the target MAU (Table 2).
    8.7.2 Identify all sample spectra with unique file names.
    8.7.3 Store on two separate computer media a copy of sample 
interferograms and processed spectra. The data shall be available to the 
Administrator on request for the length of time specified in the 
applicable regulation.
    8.7.4 For each sample spectrum, document the sampling conditions, 
the sampling time (while the cell was being filled), the time the 
spectrum was recorded, the instrumental conditions (path length, 
temperature, pressure, resolution, integration time), and the spectral 
file name. Keep a hard copy of these data sheets.
    8.8 Signal Transmittance. While sampling, monitor the signal 
transmittance through the instrumental system. If signal transmittance 
(relative to the background) drops below 95 percent in any spectral 
region where the sample does not absorb infrared energy, obtain a new 
background spectrum.
    8.9 Post-run CTS. After each sampling run, record another CTS 
spectrum.

                            8.10 Post-test QA

    8.10.1 Inspect the sample spectra immediately after the run to 
verify that the gas matrix composition was close to the expected 
(assumed) gas matrix.
    8.10.2 Verify that the sampling and instrumental parameters were 
appropriate for the conditions encountered. For example, if the moisture 
is much greater than anticipated, it will be necessary to use a shorter 
path length or dilute the sample.
    8.10.3 Compare the pre and post-run CTS spectra. They shall agree to 
within -5 percent. See FTIR Protocol, Appendix E.

                           9.0 Quality Control

    Follow the quality assurance procedures in the method, including the 
analysis of pre and post-run calibration transfer standards (Sections 
8.5 and 8.9) and the post-test quality assurance procedures in Section 
8.10.

                  10.0 Calibration and Standardization

    10.1 Signal-to-Noise Ratio (S/N). The S/N shall be sufficient to 
meet the MAU in each analytical region.
    10.2 Absorbance Pathlength. Verify the absorbance path length by 
comparing CTS spectra to reference spectra of the calibration gas(es). 
See FTIR Protocol, Appendix E.
    10.3 Instrument Resolution. Measure the line width of appropriate 
CTS band(s) and compare to reference CTS spectra to verify instrumental 
resolution.
    10.4 Apodization Function. Choose appropriate apodization function. 
Determine any appropriate mathematical transformations that are required 
to correct instrumental errors by measuring the CTS. Any mathematical 
transformations must be documented and reproducible.
    10.5 FTIR Cell Volume. Evacuate the cell to [le]5 mmHg. Measure the 
initial absolute temperature (Ti) and absolute pressure 
(Pi). Connect a wet test meter (or a calibrated dry gas 
meter), and slowly draw room air into the cell. Measure the meter volume 
(Vm), meter absolute temperature (Tm), and meter 
absolute pressure (Pm), and the cell final absolute 
temperature (Tf) and absolute pressure (Pf). 
Calculate the FTIR cell volume Vss, including that of the 
connecting tubing, as follows:
[GRAPHIC] [TIFF OMITTED] TR14JN99.048

As an alternative to the wet test meter/calibrated dry gas meter 
procedure, measure the inside dimensions of the cell cylinder and 
calculate its volume.

                             11.0 Procedure

    Refer to Sections 4.6-4.11, Sections 5, 6, and 7, and the appendices 
of the FTIR Protocol.

                   12.0 Data Analysis and Calculations

    a. Data analysis is performed using appropriate reference spectra 
whose concentrations can be verified using CTS spectra. Various 
analytical programs are available to relate sample absorbance to a 
concentration standard. Calculated concentrations should be verified by 
analyzing spectral baselines after mathematically subtracting scaled 
reference spectra from the sample spectra. A

[[Page 1093]]

full description of the data analysis and calculations may be found in 
the FTIR Protocol (Sections 4.0, 5.0, 6.0 and appendices).
    b. Correct the calculated concentrations in sample spectra for 
differences in absorption pathlength between the reference and sample 
spectra by:
[GRAPHIC] [TIFF OMITTED] TR14JN99.049

Where:

Ccorr = The pathlength corrected concentration.
Ccalc = The initial calculated concentration (output of the 
          Multicomp program designed for the compound).
Lr = The pathlength associated with the reference spectra.
Ls = The pathlength associated with the sample spectra.
Ts = The absolute temperature (K) of the sample gas.
Tr = The absolute gas temperature (K) at which reference 
          spectra were recorded.

                    13.0 Reporting and Recordkeeping

    All interferograms used in determining source concentration shall be 
stored for the period of time required in the applicable regulation. The 
Administrator has the option of requesting the interferograms recorded 
during the test in electronic form as part of the test report.

                         14.0 Method Performance

    Refer to the FTIR Protocol.

                  15.0 Pollution Prevention. [Reserved]

 Method 319--Determination of Filtration Efficiency for Paint Overspray 
                                Arrestors

                       1.0 Scope and Application.

    1.1 This method applies to the determination of the initial, 
particle size dependent, filtration efficiency for paint arrestors over 
the particle diameter range from 0.3 to 10 [mu]m. The method applies to 
single and multiple stage paint arrestors or paint arrestor media. The 
method is applicable to efficiency determinations from 0 to 99 percent. 
Two test aerosols are used--one liquid phase and one solid phase. Oleic 
acid, a low-volatility liquid (CAS Number 112-80-1), is used to simulate 
the behavior of wet paint overspray. The solid-phase aerosol is 
potassium chloride salt (KCl, CAS Number 7447-40-7) and is used to 
simulate the behavior of a dry overspray. The method is limited to 
determination of the initial, clean filtration efficiency of the 
arrestor. Changes in efficiency (either increase or decrease) due to the 
accumulation of paint overspray on and within the arrestor are not 
evaluated.
    1.2 Efficiency is defined as 1--Penetration (e.g., 70 percent 
efficiency is equal to 0.30 penetration). Penetration is based on the 
ratio of the downstream particle concentration to the upstream 
concentration. It is often more useful, from a mathematical or 
statistical point of view, to discuss the upstream and downstream counts 
in terms of penetration rather than the derived efficiency value. Thus, 
this document uses both penetration and efficiency as appropriate.
    1.3 For a paint arrestor system or subsystem which has been tested 
by this method, adding additional filtration devices to the system or 
subsystem shall be assumed to result in an efficiency of at least that 
of the original system without the requirement for additional testing. 
(For example, if the final stage of a three-stage paint arrestor system 
has been tested by itself, then the addition of the other two stages 
shall be assumed to maintain, as a minimum, the filtration efficiency 
provided by the final stage alone. Thus, in this example, if the final 
stage has been shown to meet the filtration requirements of Table 1 of 
Sec. 63.745 of subpart GG, then the final stage in combination with any 
additional paint arrestor stages also passes the filtration 
requirements.)

                         2.0 Summary of Method.

    2.1 This method applies to the determination of the fractional 
(i.e., particle-size dependent) aerosol penetration of several types of 
paint arrestors. Fractional penetration is

[[Page 1094]]

computed from aerosol concentrations measured upstream and downstream of 
an arrestor installed in a laboratory test rig. The aerosol 
concentrations upstream and downstream of the arrestors are measured 
with an aerosol analyzer that simultaneously counts and sizes the 
particles in the aerosol stream. The aerosol analyzer covers the 
particle diameter size range from 0.3 to 10 [mu]m in a minimum of 12 
contiguous sizing channels. Each sizing channel covers a narrow range of 
particle diameters. For example, Channel 1 may cover from 0.3 to 0.4 
[mu]m, Channel 2 from 0.4 to 0.5 [mu]m, * * * By taking the ratio of the 
downstream to upstream counts on a channel by channel basis, the 
penetration is computed for each of the sizing channels.
    2.2 The upstream and downstream aerosol measurements are made while 
injecting the test aerosol into the air stream upstream of the arrestor 
(ambient aerosol is removed with HEPA filters on the inlet of the test 
rig). This test aerosol spans the particle size range from 0.3 to 10 
[mu]m and provides sufficient upstream concentration in each of the 
optical particle counter (OPC) sizing channels to allow accurate 
calculation of penetration, down to penetrations of approximately 0.01 
(i.e., 1 percent penetration; 99 percent efficiency). Results are 
presented as a graph and a data table showing the aerodynamic particle 
diameter and the corresponding fractional efficiency.

                            3.0 Definitions.

    Aerodynamic Diameter--diameter of a unit density sphere having the 
same aerodynamic properties as the particle in question.
    Efficiency is defined as equal to 1--Penetration.
    Optical Particle Counter (OPC)--an instrument that counts particles 
by size using light scattering. An OPC gives particle diameters based on 
size, index of refraction, and shape.
    Penetration--the fraction of the aerosol that penetrates the filter 
at a given particle diameter. Penetration equals the downstream 
concentration divided by the upstream concentration.

                           4.0 Interferences.

    4.1 The influence of the known interferences (particle losses) are 
negated by correction of the data using blanks.

                               5.0 Safety.

    5.1 There are no specific safety precautions for this method above 
those of good laboratory practice. This standard does not purport to 
address all of the safety problems, if any, associated with its use. It 
is the responsibility of the user of this method to establish 
appropriate safety and health practices and determine the applicability 
of regulatory limitations prior to use.

                       6.0 Equipment and Supplies.

    6.1 Test Facility. A schematic diagram of a test duct used in the 
development of the method is shown in Figure 319-1.


[[Page 1095]]


[GRAPHIC] [TIFF OMITTED] TR27MR98.008


    6.1.1 The test section, paint spray section, and attached 
transitions are constructed of stainless and galvanized steel. The 
upstream and downstream ducting is 20 cm diameter polyvinyl chloride 
(PVC). The upstream transition provides a 7 [deg] angle of expansion to 
provide a uniform air flow distribution to the paint arrestors. Aerosol 
concentration is

[[Page 1096]]

measured upstream and downstream of the test section to obtain the 
challenge and penetrating aerosol concentrations, respectively. Because 
the downstream ducting runs back under the test section, the challenge 
and penetrating aerosol taps are located physically near each other, 
thereby facilitating aerosol sampling and reducing sample-line length. 
The inlet nozzles of the upstream and downstream aerosol probes are 
designed to yield isokinetic sampling conditions.
    6.1.2 The configuration and dimensions of the test duct can deviate 
from those of Figure 319-1 provided that the following key elements are 
maintained: the test duct must meet the criteria specified in Table 319-
1; the inlet air is HEPA filtered; the blower is on the upstream side of 
the duct thereby creating a positive pressure in the duct relative to 
the surrounding room; the challenge air has a temperature between 50 
[deg] and 100 [deg]F and a relative humidity of less than 65 percent; 
the angle of the upstream transition (if used) to the paint arrestor 
must not exceed 7 [deg]; the angle of the downstream transition (if 
used) from the paint arrestor must not exceed 30 [deg]; the test duct 
must provide a means for mixing the challenge aerosol with the upstream 
flow (in lieu of any mixing device, a duct length of 15 duct diameters 
fulfills this requirement); the test duct must provide a means for 
mixing any penetrating aerosol with the downstream flow (in lieu of any 
mixing device, a duct length of 15 duct diameters fulfills this 
requirement); the test section must provide a secure and leak-free 
mounting for single and multiple stage arrestors; and the test duct may 
utilize a 180 [deg] bend in the downstream duct.

------------------------------------------------------------------------

    6.2 Aerosol Generator. The aerosol generator is used to produce a 
stable aerosol covering the particle size range from 0.3 to 10 [mu]m 
diameter. The generator used in the development of this method consists 
of an air atomizing nozzle positioned at the top of a 0.30-m (12-in.) 
diameter, 1.3-m (51-in.) tall, acrylic, transparent, spray tower. This 
tower allows larger sized particles, which would otherwise foul the test 
duct and sample lines, to fall out of the aerosol. It also adds drying 
air to ensure that the KCl droplets dry to solid salt particles. After 
generation, the aerosol passes through an aerosol neutralizer (Kr85 
radioactive source) to neutralize any electrostatic charge on the 
aerosol (electrostatic charge is an unavoidable consequence of most 
aerosol generation methods). To improve the mixing of the aerosol with 
the air stream, the aerosol is injected counter to the airflow. 
Generators of other designs may be used, but they must produce a stable 
aerosol concentration over the 0.3 to 10 [mu]m diameter size range; 
provide a means of ensuring the complete drying of the KCl aerosol; and 
utilize a charge neutralizer to neutralize any electrostatic charge on 
the aerosol. The resultant challenge aerosol must meet the minimum count 
per channel and maximum concentration criteria of Table 319-1.
    6.3 Installation of Paint Arrestor. The paint arrestor is to be 
installed in the test duct in a manner that precludes air bypassing the 
arrestor. Since arrestor media are often sold unmounted, a mounting 
frame may be used to provide back support for the media in addition to 
sealing it into the duct. The mounting frame for 20 in.x20 in. arrestors 
will have minimum open internal dimensions of 18 in. square. Mounting 
frames for 24 in.x24 in. arrestors will have minimum open internal 
dimensions of 22 in. square. The open internal dimensions of the 
mounting frame shall not be less than 75 percent of the approach duct 
dimensions.

[[Page 1097]]

    6.4 Optical Particle Counter. The upstream and downstream aerosol 
concentrations are measured with a high-resolution optical particle 
counter (OPC). To ensure comparability of test results, the OPC shall 
utilize an optical design based on wide-angle light scattering and 
provided a minimum of 12 contiguous particle sizing channels from 0.3 to 
10[mu]m diameter (based on response to PSL) where, for each channel, the 
ratio of the diameter corresponding to the upper channel bound to the 
lower channel bound must not exceed 1.5.
    6.5 Aerosol Sampling System. The upstream and downstream sample 
lines must be made of rigid electrically-grounded metallic tubing having 
a smooth inside surface, and they must be rigidly secured to prevent 
movement during testing. The upstream and downstream sample lines are to 
be nominally identical in geometry. The use of a short length (100 mm 
maximum) of straight flexible tubing to make the final connection to the 
OPC is acceptable. The inlet nozzles of the upstream and downstream 
probes must be sharp-edged and of appropriate entrance diameter to 
maintain isokinetic sampling within 20 percent of the air velocity.
    6.5.1 The sampling system may be designed to acquire the upstream 
and downstream samples using (a) sequential upstream-downstream sampling 
with a single OPC, (b) simultaneous upstream and downstream sampling 
with two OPC's, or (c) sequential upstream-downstream sampling with two 
OPC's.
    6.5.2 When two particle counters are used to acquire the upstream 
and downstream counts, they must be closely matched in flowrate and 
optical design.
    6.6 Airflow Monitor. The volumetric airflow through the system shall 
be measured with a calibrated orifice plate, flow nozzle, or laminar 
flow element. The measurement device must have an accuracy of 5 percent 
or better.
    7.0 Reagents and Standards.
    7.1 The liquid test aerosol is reagent grade, 98 percent pure, oleic 
acid (Table 319-2). The solid test aerosol is KCl aerosolized from a 
solution of KCl in water. In addition to the test aerosol, a calibration 
aerosol of monodisperse polystyrene latex (PSL) spheres is used to 
verify the calibration of the OPC.

            8.0 Sample Collection, Preservation, and Storage.

    8.1 In this test, all sampling occurs in real-time, thus no samples 
are collected that require preservation or storage during the test. The 
paint arrestors are shipped and stored to avoid structural damage or 
soiling. Each arrestor may be shipped in its original box from the 
manufacturer or similar cardboard box. Arrestors are stored at the test 
site in a location that keeps them clean and dry. Each arrestor is 
clearly labeled for tracking purposes.

                          9.0 Quality Control.

    9.1 Table 319-1 lists the QC control limits.
    9.2 The standard deviation ([sigma]) of the penetration (P) for a 
given test at each of the 15 OPC sizing channels is computed from the 
coefficient of variation (CV, the standard deviation divided by the 
mean) of the upstream and downstream measurements as:
[GRAPHIC] [TIFF OMITTED] TR27MR98.009

For a properly operating system, the standard deviation of the 
penetration is < 0.10 at particle diameters from 0.3 to 3 [mu]m and less 
than 0.30 at diameters  3 [mu]m.
    9.3 Data Quality Objectives (DQO).
    9.3.1 Fractional Penetration. From the triplicate tests of each 
paint arrestor model, the standard deviation for the penetration 
measurements at each particle size (i.e., for each sizing channel of the 
OPC) is computed as:

[[Page 1098]]

[GRAPHIC] [TIFF OMITTED] TR27MR98.010

where Pi represents an individual penetration measurement, 
and P the average of the 3 (n = 3) individual measurements.
    9.3.2 Bias of the fractional penetration values is determined from 
triplicate no-filter and HEPA filter tests. These tests determine the 
measurement bias at 100 percent penetration and 0 percent penetration, 
respectively.
    9.3.3 PSL-Equivalent Light Scattering Diameter. The precision and 
bias of the OPC sizing determination are based on sampling a known 
diameter of PSL and noting whether the particle counts peak in the 
correct channel of the OPC. This is a pass/fail measurement with no 
calculations involved.
    9.3.4 Airflow. The precision of the measurement must be within 5 
percent of the set point.

                  10.0 Calibration and Standardization.

    10.1 Optical Particle Counter. The OPC must have an up-to-date 
factory calibration. Check the OPC zero at the beginning and end of each 
test by sampling HEPA-filtered air. Verify the sizing accuracy on a 
daily basis (for days when tests are performed) with 1-size PSL spheres.
    10.2 Airflow Measurement. Airflow measurement devices must have an 
accuracy of 5 percent or better. Manometers used in conjunction with the 
orifice plate must be inspected prior to use for proper level, zero, and 
mechanical integrity. Tubing connections to the manometer must be free 
from kinks and have secure connections.
    10.3 Pressure Drop. Measure pressure drop across the paint arrestor 
with an inclined manometer readable to within 0.01 in. H2O. 
Prior to use, the level and zero of the manometer, and all tubing 
connections, must be inspected and adjusted as needed.

                             11.0 Procedure.

    11.1 Filtration Efficiency. For both the oleic acid and KCl 
challenges, this procedure is performed in triplicate using a new 
arrestor for each test.

    11.1.1.6 Visually confirm the manometer zero and level. Adjust as 
needed.
    11.1.2 Clean Efficiency Test.
    11.1.2.1 Record the date and time upon beginning this section.
    11.1.2.2 Optical Particle Counter.
    11.1.2.2.1 General: Operate the OPC per the manufacturer's 
instructions allowing a minimum of 20 minutes warm up before making any 
measurements.
    11.1.2.2.2 Overload: The OPC will yield inaccurate data if the 
aerosol concentration it is attempting to measure exceeds its operating 
limit. To ensure reliable measurements, the maximum aerosol 
concentration will not exceed 10 percent of the manufacturer's claimed 
upper concentration limit corresponding to a 10 percent count error. If 
this value is exceeded, reduce the aerosol concentration until the 
acceptable conditions are met.
    11.1.2.2.3 Zero Count: Connect a HEPA capsule to the inlet of the 
OPC and obtain printouts for three samples (each a minimum of 1-minute 
each). Record maximum cumulative zero count. If the count rate exceeds 
50 counts per minute, the OPC requires servicing before continuing.
    11.1.2.2.4 PSL Check of OPC Calibration: Confirm the calibration of 
the OPC by sampling a known size PSL aerosol. Aerosolize the PSL using 
an appropriate nebulizer. Record whether the peak count is observed in 
the proper channel. If the peak is not seen in the appropriate channel, 
have the OPC recalibrated.
    11.1.2.3 Test Conditions:
    11.1.2.3.1 Airflow: The test airflow corresponds to a nominal face 
velocity of 120 FPM through the arrestor. For arrestors having nominal 
20 in.x20 in. face dimensions, this measurement corresponds to an 
airflow of 333 cfm. For arrestors having nominal face dimensions of 24 
in.x24 in., this measurement corresponds to an airflow of 480 cfm.
    11.1.2.3.2 Temperature and Relative Humidity: The temperature and 
relative humidity of the challenge air stream will be measured to within 
an accuracy of [plusmn]2 [deg]F and [plusmn]10 percent RH. To protect 
the probe from fouling, it may be removed during periods of aerosol 
generation.
    11.1.2.3.3 Barometric Pressure: Use a mercury barometer. Record the 
atmospheric pressure.
    11.1.2.4 Upstream and Downstream Background Counts.
    11.1.2.4.1 With the arrestor installed in the test duct and the 
airflow set at the proper value, turn on the data acquisition computer 
and bring up the data acquisition program.
    11.1.2.4.2 Set the OPC settings for the appropriate test sample 
duration with output for both printer and computer data collection.
    11.1.2.4.3 Obtain one set of upstream-downstream background 
measurements.
    11.1.2.4.4 After obtaining the upstream-downstream measurements, 
stop data acquisition.
    11.1.2.5 Efficiency Measurements:
    11.1.2.5.1 Record the arrestor pressure drop.
    11.1.2.5.2 Turn on the Aerosol Generator. Begin aerosol generation 
and record the operating parameters.
    11.1.2.5.3 Monitor the particle counts. Allow a minimum of 5 minutes 
for the generator to stabilize.
    11.1.2.5.4 Confirm that the total particle count does not exceed the 
predetermined upper limit. Adjust generator as needed.
    11.1.2.5.5 Confirm that a minimum of 50 particle counts are measured 
in the upstream sample in each of the OPC channels per sample. (A 
minimum of 50 counts per channel per sample will yield the required 
minimum 500 counts per channel total for the 10 upstream samples as 
specified in Table 319-1.) Adjust generator or sample time as needed.
    11.1.2.5.6 If you are unable to obtain a stable concentration within 
the concentration limit and with the 50 count minimum per channel, 
adjust the aerosol generator.
    11.1.2.5.7 When the counts are stable, perform repeated upstream-
downstream sampling until 10 upstream-downstream measurements are 
obtained.
    11.1.2.5.8 After collection of the 10 upstream-downstream samples, 
stop data acquisition and allow 2 more minutes for final purging of 
generator.
    11.1.2.5.9 Obtain one additional set of upstream-downstream 
background samples.
    11.1.2.5.10 After obtaining the upstream-downstream background 
samples, stop data acquisition.
    11.1.2.5.11 Record the arrestor pressure drop.
    11.1.2.5.12 Turn off blower.
    11.1.2.5.13 Remove the paint arrestor assembly from the test duct. 
Note any signs of physical deterioration.
    11.1.2.5.14 Remove the arrestor from the frame and place the 
arrestor in an appropriate storage bag.
    11.2 Control Test: 100 Percent Penetration Test. A 100 percent 
penetration test must be performed immediately before each individual 
paint arrestor test using the same challenge aerosol substance (i.e., 
oleic acid or KCl) as to be used in the arrestor test. These tests are 
performed with no arrestor installed in the test housing. This test is a 
relatively stringent test of the adequacy of the overall duct, sampling, 
measurement, and aerosol generation system. The test is performed as a 
normal penetration test except the paint arrestor is not used. A perfect 
system would yield a measured penetration of 1 at all particle sizes. 
Deviations from 1

[[Page 1100]]

can occur due to particle losses in the duct, differences in the degree 
of aerosol uniformity (i.e., mixing) at the upstream and downstream 
probes, and differences in particle transport efficiency in the upstream 
and downstream sampling lines.
    11.3 Control Test: 0 Percent Penetration. One 0 percent penetration 
test must be performed at least monthly during testing. The test is 
performed by using a HEPA filter rather than a paint arrestor. This test 
assesses the adequacy of the instrument response time and sample line 
lag.

                  12.0 Data Analysis and Calculations.

    12.1 Analysis. The analytical procedures for the fractional 
penetration and flow velocity measurements are described in Section 11. 
Note that the primary measurements, those of the upstream and downstream 
aerosol concentrations, are performed with the OPC which acquires the 
sample and analyzes it in real time. Because all the test data are 
collected in real time, there are no analytical procedures performed 
subsequent to the actual test, only data analysis.
    12.2 Calculations.
    12.2.1 Penetration.

                              Nomenclature

U = Upstream particle count
D = Downstream particle count
Ub = Upstream background count
Db = Downstream background count
P100 = 100 percent penetration value determined immediately 
          prior to the arrestor test computed for each channel as:
          [GRAPHIC] [TIFF OMITTED] TR27MR98.011
          
P = Penetration of the arrestor corrected for P100
[rho]= sample standard deviation
CV = coefficient of variation = [rho]/mean
E = Efficiency.

    Overbar denotes arithmetic mean of quantity.
    Analysis of each test involves the following quantities:
    [sbull] P100 value for each sizing channel from the 100 
percent penetration control test,
    [sbull] 2 upstream background values,
    [sbull] 2 downstream background values,
    [sbull] 10 upstream values with aerosol generator on, and
    [sbull] 10 downstream values with aerosol generator on.
    Using the values associated with each sizing channel, the 
penetration associated with each particle-sizing channel is calculated 
as:
[GRAPHIC] [TIFF OMITTED] TR27MR98.012

[GRAPHIC] [TIFF OMITTED] TR27MR98.013

    Most often, the background levels are small compared to the values 
when the aerosol generator is on.
    12.3 The relationship between the physical diameter 
(DPhysical) as measured by the OPC to the aerodynamic 
diameter (DAero) is given by:
[GRAPHIC] [TIFF OMITTED] TR27MR98.014

Where:

pO = unit density of 1 g/cm3.
pParticle = the density of the particle, 0.89 g/
          cm3 for oleic acid.
CCFPhysical = the Cunningham Correction Factor at 
          DPhysical.
CCFAero = the Cunningham Correction Factor at 
          DAero.

    12.4 Presentation of Results. For a given arrestor, results will be 
presented for:
    [sbull] Triplicate arrestor tests with the liquid-phase challenge 
aerosol,
    sbull; Triplicate arrestor tests with the solid-phase challenge 
aerosol,
    sbull; Triplicate 100 percent penetration tests with the liquid-
phase challenge aerosol,
    sbull; Triplicate 100 percent penetration tests with the solid-phase 
challenge aerosol, and
    sbull; One 0 percent filter test (using either the liquid-phase or 
solid-phase aerosol and performed at least monthly).
    12.4.1 Results for the paint arrestor test must be presented in both 
graphical and tabular form. The X-axis of the graph will be a 
logarithmic scale of aerodynamic diameter from 0.1 to 100 [mu]m. The Y-
axis will be efficiency (%) on a linear scale from 0 to 100. Plots for 
each individual run and a plot of

[[Page 1101]]

the average of triplicate solid-phase and of the average triplicate 
liquid-phase tests must be prepared. All plots are to be based on point-
to-point plotting (i.e., no curve fitting is to be used). The data are 
to be plotted based on the geometric mean diameter of each of the OPC's 
sizing channels.
    12.4.2 Tabulated data from each test must be provided. The data must 
include the upper and lower diameter bound and geometric mean diameter 
of each of the OPC sizing channels, the background particle counts for 
each channel for each sample, the upstream particle counts for each 
channel for each sample, the downstream particle counts for each channel 
for each sample, the 100 percent penetration values computed for each 
channel, and the 0 percent penetration values computed for each channel.

                       13.0 Pollution Prevention.

    13.1 The quantities of materials to be aerosolized should be 
prepared in accord with the amount needed for the current tests so as to 
prevent wasteful excess.

                         14.0 Waste Management.

    14.1 Paint arrestors may be returned to originator, if requested, or 
disposed of with regular laboratory waste.

   Test Method 320--Measurement of Vapor Phase Organic and Inorganic 
 Emissions by Extractive Fourier Transform Infrared (FTIR) Spectroscopy

                            1.0 Introduction.

    Persons unfamiliar with basic elements of FTIR spectroscopy should 
not attempt to use this method. This method describes sampling and 
analytical procedures for extractive emission measurements using Fourier 
transform infrared (FTIR) spectroscopy. Detailed analytical procedures 
for interpreting infrared spectra are described in the ``Protocol for 
the Use of Extractive Fourier Transform Infrared (FTIR) Spectrometry in 
Analyses of Gaseous Emissions from Stationary Sources,'' hereafter 
referred to as the ``Protocol.'' Definitions not given in this method 
are given in appendix A of the Protocol. References to specific sections 
in the Protocol are made throughout this Method. For additional 
information refer to references 1 and 2, and other EPA reports, which 
describe the use of FTIR spectrometry in specific field measurement 
applications and validation tests. The sampling procedure described here 
is extractive. Flue gas is extracted through a heated gas transport and 
handling system. For some sources, sample conditioning systems may be 
applicable. Some examples are given in this method.

    Note: sample conditioning systems may be used providing the method 
validation requirements in Sections 9.2 and 13.0 of this method are met.

                      1.1 Scope and Applicability.

    1.1.1 Analytes. Analytes include hazardous air pollutants (HAPs) for 
which EPA reference spectra have been developed. Other compounds can 
also be measured with this method if reference spectra are prepared 
according to section 4.6 of the protocol.
    1.1.2 Applicability. This method applies to the analysis of vapor 
phase organic or inorganic compounds which absorb energy in the mid-
infrared spectral region, about 400 to 4000 cm-1 (25 to 2.5 
[mu]m). This method is used to determine compound-specific 
concentrations in a multi-component vapor phase sample, which is 
contained in a closed-path gas cell. Spectra of samples are collected 
using double beam infrared absorption spectroscopy. A computer program 
is used to analyze spectra and report compound concentrations.
    1.2 Method Range and Sensitivity. Analytical range and sensitivity 
depend on the frequency-dependent analyte absorptivity, instrument 
configuration, data collection parameters, and gas stream composition. 
Instrument factors include: (a) spectral resolution, (b) interferometer 
signal averaging time, (c) detector sensitivity and response, and (d) 
absorption path length.
    1.2.1 For any optical configuration the analytical range is between 
the absorbance values of about .01 (infrared transmittance relative to 
the background = 0.98) and 1.0
(T = 0.1). (For absorbance  1.0 the relation between 
absorbance and concentration may not be linear.)
    1.2.2 The concentrations associated with this absorbance range 
depend primarily on the cell path length and the sample temperature. An 
analyte absorbance greater than 1.0, can be lowered by decreasing the 
optical path length. Analyte absorbance increases with a longer path 
length. Analyte detection also depends on the presence of other species 
exhibiting absorbance in the same analytical

[[Page 1102]]

region. Additionally, the estimated lower absorbance (A) limit
(A = 0.01) depends on the root mean square deviation (RMSD) noise in the 
analytical region.
    1.2.3 The concentration range of this method is determined by the 
choice of optical configuration.
    1.2.3.1 The absorbance for a given concentration can be decreased by 
decreasing the path length or by diluting the sample. There is no 
practical upper limit to the measurement range.
    1.2.3.2 The analyte absorbance for a given concentration may be 
increased by increasing the cell path length or (to some extent) using a 
higher resolution. Both modifications also cause a corresponding 
increased absorbance for all compounds in the sample, and a decrease in 
the signal throughput. For this reason the practical lower detection 
range (quantitation limit) usually depends on sample characteristics 
such as moisture content of the gas, the presence of other interferants, 
and losses in the sampling system.
    1.3 Sensitivity. The limit of sensitivity for an optical 
configuration and integration time is determined using appendix D of the 
Protocol: Minimum Analyte Uncertainty, (MAU). The MAU depends on the 
RMSD noise in an analytical region, and on the absorptivity of the 
analyte in the same region.
    1.4 Data Quality. Data quality shall be determined by executing 
Protocol pre-test procedures in appendices B to H of the protocol and 
post-test procedures in appendices I and J of the protocol.
    1.4.1 Measurement objectives shall be established by the choice of 
detection limit (DLi) and analytical uncertainty 
(AUi) for each analyte.
    1.4.2 An instrumental configuration shall be selected. An estimate 
of gas composition shall be made based on previous test data, data from 
a similar source or information gathered in a pre-test site survey. 
Spectral interferants shall be identified using the selected 
DLi and AUi and band areas from reference spectra 
and interferant spectra. The baseline noise of the system shall be 
measured in each analytical region to determine the MAU of the 
instrument configuration for each analyte and interferant 
(MIUi).
    1.4.3 Data quality for the application shall be determined, in part, 
by measuring the RMS (root mean square) noise level in each analytical 
spectral region (appendix C of the Protocol). The RMS noise is defined 
as the RMSD of the absorbance values in an analytical region from the 
mean absorbance value in the region.
    1.4.4 The MAU is the minimum analyte concentration for which the 
AUi can be maintained; if the measured analyte concentration 
is less than MAUi then data quality are unacceptable.

                          2.0 Summary of Method

    2.1 Principle. References 4 through 7 provide background material on 
infrared spectroscopy and quantitative analysis. A summary is given in 
this section.
    2.1.1 Infrared absorption spectroscopy is performed by directing an 
infrared beam through a sample to a detector. The frequency-dependent 
infrared absorbance of the sample is measured by comparing this detector 
signal (single beam spectrum) to a signal obtained without a sample in 
the beam path (background).
    2.1.2 Most molecules absorb infrared radiation and the absorbance 
occurs in a characteristic and reproducible pattern. The infrared 
spectrum measures fundamental molecular properties and a compound can be 
identified from its infrared spectrum alone.
    2.1.3 Within constraints, there is a linear relationship between 
infrared absorption and compound concentration. If this frequency 
dependent relationship (absorptivity) is known (measured), it can be 
used to determine compound concentration in a sample mixture.
    2.1.4 Absorptivity is measured by preparing, in the laboratory, 
standard samples of compounds at known concentrations and measuring the 
FTIR ``reference spectra'' of these standard samples. These ``reference 
spectra'' are then used in sample analysis: (1) Compounds are detected 
by matching sample absorbance bands with bands in reference spectra, and 
(2) concentrations are measured by comparing sample band intensities 
with reference band intensities.
    2.1.5 This method is self-validating provided that the results meet 
the performance requirement of the QA spike in sections 8.6.2 and 9.0 of 
this method, and results from a previous method validation study support 
the use of this method in the application.
    2.2 Sampling and Analysis. In extractive sampling a probe assembly 
and pump are used to extract gas from the exhaust of the affected source 
and transport the sample to the FTIR gas cell. Typically, the sampling 
apparatus is similar to that used for single-component continuous 
emission monitor (CEM) measurements.
    2.2.1 The digitized infrared spectrum of the sample in the FTIR gas 
cell is measured and stored on a computer. Absorbance band intensities 
in the spectrum are related to sample concentrations by what is commonly 
referred to as Beer's Law.

Where:

Ai = absorbance at a given frequency of the ith sample 
          component.
ai = absorption coefficient (absorptivity) of the ith sample 
          component.
b = path length of the cell.

[[Page 1103]]

ci = concentration of the ith sample component.

    2.2.2 Analyte spiking is used for quality assurance (QA). In this 
procedure (section 8.6.2 of this method) an analyte is spiked into the 
gas stream at the back end of the sample probe. Analyte concentrations 
in the spiked samples are compared to analyte concentrations in unspiked 
samples. Since the concentration of the spike is known, this procedure 
can be used to determine if the sampling system is removing the spiked 
analyte(s) from the sample stream.
    2.3 Reference Spectra Availability. Reference spectra of over 100 
HAPs are available in the EPA FTIR spectral library on the EMTIC 
(Emission Measurement Technical Information Center) computer bulletin 
board service and at internet address http://info.arnold.af.mil/epa/
welcome.htm. Reference spectra for HAPs, or other analytes, may also be 
prepared according to section 4.6 of the Protocol.
    2.4 Operator Requirements. The FTIR analyst shall be trained in 
setting up the instrumentation, verifying the instrument is functioning 
properly, and performing routine maintenance. The analyst must evaluate 
the initial sample spectra to determine if the sample matrix is 
consistent with pre-test assumptions and if the instrument configuration 
is suitable. The analyst must be able to modify the instrument 
configuration, if necessary.
    2.4.1 The spectral analysis shall be supervised by someone familiar 
with EPA FTIR Protocol procedures.
    2.4.2 A technician trained in instrumental test methods is qualified 
to install and operate the sampling system. This includes installing the 
probe and heated line assembly, operating the analyte spike system, and 
performing moisture and flow measurements.

                             3.0 Definitions

    See appendix A of the Protocol for definitions relating to infrared 
spectroscopy. Additional definitions are given in sections 3.1 through 
3.29.
    3.1 Analyte. A compound that this method is used to measure. The 
term ``target analyte'' is also used. This method is multi-component and 
a number of analytes can be targeted for a test.
    3.2 Reference Spectrum. Infrared spectrum of an analyte prepared 
under controlled, documented, and reproducible laboratory conditions 
according to procedures in section 4.6 of the Protocol. A library of 
reference spectra is used to measure analytes in gas samples.
    3.3 Standard Spectrum. A spectrum that has been prepared from a 
reference spectrum through a (documented) mathematical operation. A 
common example is de-resolving of reference spectra to lower-resolution 
standard spectra (Protocol, appendix K to the addendum of this method). 
Standard spectra, prepared by approved, and documented, procedures can 
be used as reference spectra for analysis.
    3.4 Concentration. In this method concentration is expressed as a 
molar concentration, in ppm-meters, or in (ppm-meters)/K, where K is the 
absolute temperature (Kelvin). The latter units allow the direct 
comparison of concentrations from systems using different optical 
configurations or sampling temperatures.
    3.5 Interferant. A compound in the sample matrix whose infrared 
spectrum overlaps with part of an analyte spectrum. The most accurate 
analyte measurements are achieved when reference spectra of interferants 
are used in the quantitative analysis with the analyte reference 
spectra. The presence of an interferant can increase the analytical 
uncertainty in the measured analyte concentration.
    3.6 Gas Cell. A gas containment cell that can be evacuated. It is 
equipped with the optical components to pass the infrared beam through 
the sample to the detector. Important cell features include: path length 
(or range if variable), temperature range, materials of construction, 
and total gas volume.
    3.7 Sampling System. Equipment used to extract the sample from the 
test location and transport the sample gas to the FTIR analyzer. This 
includes sample conditioning systems.
    3.8 Sample Analysis. The process of interpreting the infrared 
spectra to obtain sample analyte concentrations. This process is usually 
automated using a software routine employing a classical least squares 
(cls), partial least squares (pls), or K- or P-matrix method.
    3.9 One hundred percent line. A double beam transmittance spectrum 
obtained by combining two background single beam spectra. Ideally, this 
line is equal to 100 percent transmittance (or zero absorbance) at every 
frequency in the spectrum. Practically, a zero absorbance line is used 
to measure the baseline noise in the spectrum.
    3.10 Background Deviation. A deviation from 100 percent 
transmittance in any region of the 100 percent line. Deviations greater 
than [plusmn]5 percent in an analytical region are unacceptable 
(absorbance of 0.021 to -0.022). Such deviations indicate a change in 
the instrument throughput relative to the background single beam.
    3.11 Batch Sampling. A procedure where spectra of discreet, static 
samples are collected. The gas cell is filled with sample and the cell 
is isolated. The spectrum is collected. Finally, the cell is evacuated 
to prepare for the next sample.
    3.12 Continuous Sampling. A procedure where spectra are collected 
while sample gas

[[Page 1104]]

is flowing through the cell at a measured rate.
    3.13 Sampling resolution. The spectral resolution used to collect 
sample spectra.
    3.14 Truncation. Limiting the number of interferogram data points by 
deleting points farthest from the center burst (zero path difference, 
ZPD).
    3.15 Zero filling. The addition of points to the interferogram. The 
position of each added point is interpolated from neighboring real data 
points. Zero filling adds no information to the interferogram, but 
affects line shapes in the absorbance spectrum (and possibly analytical 
results).
    3.16 Reference CTS. Calibration Transfer Standard spectra that were 
collected with reference spectra.
    3.17 CTS Standard. CTS spectrum produced by applying a de-resolution 
procedure to a reference CTS.
    3.18 Test CTS. CTS spectra collected at the sampling resolution 
using the same optical configuration as for sample spectra. Test spectra 
help verify the resolution, temperature and path length of the FTIR 
system.
    3.19 RMSD. Root Mean Square Difference, defined in EPA FTIR 
Protocol, appendix A.
    3.20 Sensitivity. The noise-limited compound-dependent detection 
limit for the FTIR system configuration. This is estimated by the MAU. 
It depends on the RMSD in an analytical region of a zero absorbance 
line.
    3.21 Quantitation Limit. The lower limit of detection for the FTIR 
system configuration in the sample spectra. This is estimated by 
mathematically subtracting scaled reference spectra of analytes and 
interferences from sample spectra, then measuring the RMSD in an 
analytical region of the subtracted spectrum. Since the noise in 
subtracted sample spectra may be much greater than in a zero absorbance 
spectrum, the quantitation limit is generally much higher than the 
sensitivity. Removing spectral interferences from the sample or 
improving the spectral subtraction can lower the quantitation limit 
toward (but not below) the sensitivity.
    3.22 Independent Sample. A unique volume of sample gas; there is no 
mixing of gas between two consecutive independent samples. In continuous 
sampling two independent samples are separated by at least 5 cell 
volumes. The interval between independent measurements depends on the 
cell volume and the sample flow rate (through the cell).
    3.23 Measurement. A single spectrum of flue gas contained in the 
FTIR cell.
    3.24 Run. A run consists of a series of measurements. At a minimum a 
run includes 8 independent measurements spaced over 1 hour.
    3.25 Validation. Validation of FTIR measurements is described in 
sections 13.0 through 13.4 of this method. Validation is used to verify 
the test procedures for measuring specific analytes at a source. 
Validation provides proof that the method works under certain test 
conditions.
    3.26 Validation Run. A validation run consists of at least 24 
measurements of independent samples. Half of the samples are spiked and 
half are not spiked. The length of the run is determined by the interval 
between independent samples.
    3.27 ning. Screening is used when there is little or no available 
information about a source. The purpose of screening is to determine 
what analytes are emitted and to obtain information about important 
sample characteristics such as moisture, temperature, and interferences. 
Screening results are semi-quantitative (estimated concentrations) or 
qualitative (identification only). Various optical and sampling 
configurations may be used. Sample conditioning systems may be evaluated 
for their effectiveness in removing interferences. It is unnecessary to 
perform a complete run under any set of sampling conditions. Spiking is 
not necessary, but spiking can be a useful screening tool for evaluating 
the sampling system, especially if a reactive or soluble analyte is used 
for the spike.
    3.28 Emissions Test. An FTIR emissions test is performed according 
specific sampling and analytical procedures. These procedures, for the 
target analytes and the source, are based on previous screening and 
validation results. Emission results are quantitative. A QA spike 
(sections 8.6.2 and 9.2 of this method) is performed under each set of 
sampling conditions using a representative analyte. Flow, gas 
temperature and diluent data are recorded concurrently with the FTIR 
measurements to provide mass emission rates for detected compounds.
    3.29 Surrogate. A surrogate is a compound that is used in a QA spike 
procedure (section 8.6.2 of this method) to represent other compounds. 
The chemical and physical properties of a surrogate shall be similar to 
the compounds it is chosen to represent. Under given sampling 
conditions, usually a single sampling factor is of primary concern for 
measuring the target analytes: for example, the surrogate spike results 
can be representative for analytes that are more reactive, more soluble, 
have a lower absorptivity, or have a lower vapor pressure than the 
surrogate itself.

                            4.0 Interferences

    Interferences are divided into two classifications: analytical and 
sampling.
    4.1 Analytical Interferences. An analytical interference is a 
spectral feature that complicates (in extreme cases may prevent) the 
analysis of an analyte. Analytical interferences are classified as 
background or spectral interference.
    4.1.1 Background Interference. This results from a change in 
throughput relative to the

[[Page 1105]]

single beam background. It is corrected by collecting a new background 
and proceeding with the test. In severe instances the cause must be 
identified and corrected. Potential causes include: (1) Deposits on 
reflective surfaces or transmitting windows, (2) changes in detector 
sensitivity, (3) a change in the infrared source output, or (4) failure 
in the instrument electronics. In routine sampling throughput may 
degrade over several hours. Periodically a new background must be 
collected, but no other corrective action will be required.
    4.1.2 Spectral Interference. This results from the presence of 
interfering compound(s) (interferant) in the sample. Interferant 
spectral features overlap analyte spectral features. Any compound with 
an infrared spectrum, including analytes, can potentially be an 
interferant. The Protocol measures absorbance band overlap in each 
analytical region to determine if potential interferants shall be 
classified as known interferants (FTIR Protocol, section 4.9 and 
appendix B). Water vapor and CO2 are common spectral 
interferants. Both of these compounds have strong infrared spectra and 
are present in many sample matrices at high concentrations relative to 
analytes. The extent of interference depends on the (1) interferant 
concentration, (2) analyte concentration, and (3) the degree of band 
overlap. Choosing an alternate analytical region can minimize or avoid 
the spectral interference. For example, CO2 interferes with 
the analysis of the 670 cm-1 benzene band. However, benzene 
can also be measured near 3000 cm-1 (with less sensitivity).
    4.2 Sampling System Interferences. These prevent analytes from 
reaching the instrument. The analyte spike procedure is designed to 
measure sampling system interference, if any.
    4.2.1 Temperature. A temperature that is too low causes condensation 
of analytes or water vapor. The materials of the sampling system and the 
FTIR gas cell usually set the upper limit of temperature.
    4.2.2 Reactive Species. Anything that reacts with analytes. Some 
analytes, like formaldehyde, polymerize at lower temperatures.
    4.2.3 Materials. Poor choice of material for probe, or sampling line 
may remove some analytes. For example, HF reacts with glass components.
    4.2.4 Moisture. In addition to being a spectral interferant, 
condensed moisture removes soluble compounds.

                               5.0 Safety

    The hazards of performing this method are those associated with any 
stack sampling method and the same precautions shall be followed. Many 
HAPs are suspected carcinogens or present other serious health risks. 
Exposure to these compounds should be avoided in all circumstances. For 
instructions on the safe handling of any particular compound, refer to 
its material safety data sheet. When using analyte standards, always 
ensure that gases are properly vented and that the gas handling system 
is leak free. (Always perform a leak check with the system under maximum 
vacuum and, again, with the system at greater than ambient pressure.) 
Refer to section 8.2 of this method for leak check procedures. This 
method does not address all of the potential safety risks associated 
with its use. Anyone performing this method must follow safety and 
health practices consistent with applicable legal requirements and with 
prudent practice for each application.

                       6.0 Equipment and Supplies

    Note: Mention of trade names or specific products does not 
constitute endorsement by the Environmental Protection Agency.

    The equipment and supplies are based on the schematic of a sampling 
system shown in Figure 1. Either the batch or continuous sampling 
procedures may be used with this sampling system. Alternative sampling 
configurations may also be used, provided that the data quality 
objectives are met as determined in the post-analysis evaluation. Other 
equipment or supplies may be necessary, depending on the design of the 
sampling system or the specific target analytes.
    6.1 Sampling Probe. Glass, stainless steel, or other appropriate 
material of sufficient length and physical integrity to sustain heating, 
prevent adsorption of analytes, and to transport analytes to the 
infrared gas cell. Special materials or configurations may be required 
in some applications. For instance, high stack sample temperatures may 
require special steel or cooling the probe. For very high moisture 
sources it may be desirable to use a dilution probe.
    6.2 Particulate Filters. A glass wool plug (optional) inserted at 
the probe tip (for large particulate removal) and a filter (required) 
rated for 99 percent removal efficiency at 1-micron (e.g., Balston'') 
connected at the outlet of the heated probe.
    6.3 Sampling Line/Heating System. Heated (sufficient to prevent 
condensation) stainless steel, polytetrafluoroethane, or other material 
inert to the analytes.
    6.4 Gas Distribution Manifold. A heated manifold allowing the 
operator to control flows of gas standards and samples directly to the 
FTIR system or through sample conditioning systems. Usually includes 
heated flow meter, heated valve for selecting and sending sample to the 
analyzer, and a by-pass vent. This is typically constructed of stainless 
steel tubing and fittings, and high-temperature valves.
    6.5 Stainless Steel Tubing. Type 316, appropriate diameter (e.g., 3/
8 in.) and length for

[[Page 1106]]

heated connections. Higher grade stainless may be desirable in some 
applications.
    6.6 Calibration/Analyte Spike Assembly. A three way valve assembly 
(or equivalent) to introduce analyte or surrogate spikes into the 
sampling system at the outlet of the probe upstream of the out-of-stack 
particulate filter and the FTIR analytical system.
    6.7 Mass Flow Meter (MFM). These are used for measuring analyte 
spike flow. The MFM shall be calibrated in the range of 0 to 5 L/min and 
be accurate to [plusmn] 2 percent (or better) of the flow meter span.
    6.8 Gas Regulators. Appropriate for individual gas standards.
    6.9 Polytetrafluoroethane Tubing. Diameter (e.g., \3/8\ in.) and 
length suitable to connect cylinder regulators to gas standard manifold.
    6.10 Sample Pump. A leak-free pump (e.g., KNFTM), with 
by-pass valve, capable of producing a sample flow rate of at least 10 L/
min through 100 ft of sample line. If the pump is positioned upstream of 
the distribution manifold and FTIR system, use a heated pump that is 
constructed from materials non-reactive to the analytes. If the pump is 
located downstream of the FTIR system, the gas cell sample pressure will 
be lower than ambient pressure and it must be recorded at regular 
intervals.
    6.11 Gas Sample Manifold. Secondary manifold to control sample flow 
at the inlet to the FTIR manifold. This is optional, but includes a by-
pass vent and heated rotameter.
    6.12 Rotameter. A 0 to 20 L/min rotameter. This meter need not be 
calibrated.
    6.13 FTIR Analytical System. Spectrometer and detector, capable of 
measuring the analytes to the chosen detection limit. The system shall 
include a personal computer with compatible software allowing automated 
collection of spectra.
    6.14 FTIR Cell Pump. Required for the batch sampling technique, 
capable of evacuating the FTIR cell volume within 2 minutes. The pumping 
speed shall allow the operator to obtain 8 sample spectra in 1 hour.
    6.15 Absolute Pressure Gauge. Capable of measuring pressure from 0 
to 1000 mmHg to within[plusmn] 2.5 mmHg (e.g., BaratronTM).
    6.16 Temperature Gauge. Capable of measuring the cell temperature to 
within [plusmn] 2 [deg]C.
    6.17 Sample Conditioning. One option is a condenser system, which is 
used for moisture removal. This can be helpful in the measurement of 
some analytes. Other sample conditioning procedures may be devised for 
the removal of moisture or other interfering species.
    6.17.1 The analyte spike procedure of section 9.2 of this method, 
the QA spike procedure of section 8.6.2 of this method, and the 
validation procedure of section 13 of this method demonstrate whether 
the sample conditioning affects analyte concentrations. Alternatively, 
measurements can be made with two parallel FTIR systems; one measuring 
conditioned sample, the other measuring unconditioned sample.
    6.17.2 Another option is sample dilution. The dilution factor 
measurement must be documented and accounted for in the reported 
concentrations. An alternative to dilution is to lower the sensitivity 
of the FTIR system by decreasing the cell path length, or to use a 
short-path cell in conjunction with a long path cell to measure more 
than one concentration range.

                       7.0 Reagents and Standards

    7.1 Analyte(s) and Tracer Gas. Obtain a certified gas cylinder 
mixture containing all of the analyte(s) at concentrations 
within[plusmn] 2 percent of the emission source levels (expressed in 
ppm-meter/K). If practical, the analyte standard cylinder shall also 
contain the tracer gas at a concentration which gives a measurable 
absorbance at a dilution factor of at least 10:1. Two ppm SF6 
is sufficient for a path length of 22 meters at 250 [deg]F.
    7.2 Calibration Transfer Standard(s). Select the calibration 
transfer standards (CTS) according to section 4.5 of the FTIR Protocol. 
Obtain a National Institute of Standards and Technology (NIST) traceable 
gravimetric standard of the CTS ([plusmn] 2 percent).
    7.3 Reference Spectra. Obtain reference spectra for each analyte, 
interferant, surrogate, CTS, and tracer. If EPA reference spectra are 
not available, use reference spectra prepared according to procedures in 
section 4.6 of the EPA FTIR Protocol.

                   8.0 Sampling and Analysis Procedure

    Three types of testing can be performed: (1) Screening, (2) 
emissions test, and (3) validation. Each is defined in section 3 of this 
method. Determine the purpose(s) of the FTIR test. Test requirements 
include: (a) AUi, DLi, overall fractional 
uncertainty, OFUi, maximum expected concentration 
(CMAXi), and tAN for each, (b) potential 
interferants, (c) sampling system factors, e.g., minimum absolute cell 
pressure, (Pmin), FTIR cell volume (VSS), 
estimated sample absorption pathlength, LS', estimated sample 
pressure, PS', TS', signal integration time 
(tSS), minimum instrumental linewidth, MIL, fractional error, 
and (d) analytical regions, e.g., m = 1 to M, lower wavenumber position, 
FLm, center wavenumber position, FCm, and upper wavenumber 
position, FUm, plus interferants, upper wavenumber position 
of the CTS absorption band, FFUm, lower wavenumber position 
of the CTS absorption band, FFLm, wavenumber range FNU to 
FNL. If necessary, sample and acquire an initial spectrum. From analysis 
of this preliminary spectrum determine a suitable operational path 
length. Set up the sampling train as shown in Figure 1 or use an 
appropriate alternative configuration. Sections 8.1 through 8.11 of this 
method provide guidance on pre-

[[Page 1107]]

test calculations in the EPA protocol, sampling and analytical 
procedures, and post-test protocol calculations.
    8.1 Pretest Preparations and Evaluations. Using the procedure in 
section 4.0 of the FTIR Protocol, determine the optimum sampling system 
configuration for measuring the target analytes. Use available 
information to make reasonable assumptions about moisture content and 
other interferences.
    8.1.1 Analytes. Select the required detection limit (DLi) 
and the maximum permissible analytical uncertainty (AUi) for 
each analyte (labeled from 1 to i). Estimate, if possible, the maximum 
expected concentration for each analyte, CMAXi. The expected 
measurement range is fixed by DLi and CMAXi for 
each analyte (i).
    8.1.2 Potential Interferants. List the potential interferants. This 
usually includes water vapor and CO2, but may also include 
some analytes and other compounds.
    8.1.3. Optical Configuration. Choose an optical configuration that 
can measure all of the analytes within the absorbance range of .01 to 
1.0 (this may require more than one path length). Use Protocol sections 
4.3 to 4.8 for guidance in choosing a configuration and measuring CTS.
    8.1.4 Fractional Reproducibility Uncertainty (FRUi). The 
FRU is determined for each analyte by comparing CTS spectra taken before 
and after the reference spectra were measured. The EPA para-xylene 
reference spectra were collected on 10/31/91 and 11/01/91 with 
corresponding CTS spectra ``cts1031a,'' and ``cts1101b.'' The CTS 
spectra are used to estimate the reproducibility (FRU) in the system 
that was used to collect the references. The FRU must be < AU. Appendix 
E of the protocol is used to calculate the FRU from CTS spectra. Figure 
2 plots results for 0.25 cm-1 CTS spectra in EPA reference 
library: S3 (cts1101b-cts1031a), and S4 
[(cts1101b+cts1031a)/2]. The RMSD (SRMS) is calculated in the subtracted 
baseline, S3, in the corresponding CTS region from 850 to 
1065 cm-1. The area (BAV) is calculated in the same region of 
the averaged CTS spectrum, S4.
    8.1.5 Known Interferants. Use appendix B of the EPA FTIR Protocol.
    8.1.6 Calculate the Minimum Analyte Uncertainty, MAU (section 1.3 of 
this method discusses MAU and protocol appendix D gives the MAU 
procedure). The MAU for each analyte, i, and each analytical region, m, 
depends on the RMS noise.
    8.1.7 Analytical Program. See FTIR Protocol, section 4.10. Prepare 
computer program based on the chosen analytical technique. Use as input 
reference spectra of all target analytes and expected interferants. 
Reference spectra of additional compounds shall also be included in the 
program if their presence (even if transient) in the samples is 
considered possible. The program output shall be in ppm (or ppb) and 
shall be corrected for differences between the reference path length, 
LR, temperature, TR, and pressure, PR, 
and the conditions used for collecting the sample spectra. If sampling 
is performed at ambient pressure, then any pressure correction is 
usually small relative to corrections for path length and temperature, 
and may be neglected.

                             8.2 Leak-Check

    8.2.1 Sampling System. A typical FTIR extractive sampling train is 
shown in Figure 1. Leak check from the probe tip to pump outlet as 
follows: Connect a 0-to 250-mL/min rate meter (rotameter or bubble 
meter) to the outlet of the pump. Close off the inlet to the probe, and 
record the leak rate. The leak rate shall be [le]200 mL/min.
    8.2.2 Analytical System Leak check. Leak check the FTIR cell under 
vacuum and under pressure (greater than ambient). Leak check connecting 
tubing and inlet manifold under pressure.
    8.2.2.1 For the evacuated sample technique, close the valve to the 
FTIR cell, and evacuate the absorption cell to the minimum absolute 
pressure Pmin. Close the valve to the pump, and determine the 
change in pressure [Delta]Pv after 2 minutes.
    8.2.2.2 For both the evacuated sample and purging techniques, 
pressurize the system to about 100 mmHg above atmospheric pressure. 
Isolate the pump and determine the change in pressure 
[Delta]Pp after 2 minutes.
    8.2.2.3 Measure the barometric pressure, Pb in mmHg.
    8.2.2.4 Determine the percent leak volume %VL for the 
signal integration time tSS and for [Delta]Pmax, 
i.e., the larger of [Delta]Pv or [Delta]Pp, as 
follows:
[GRAPHIC] [TIFF OMITTED] TR14JN99.004

where 50 = 100% divided by the leak-check time of 2 minutes. 8.2.2.5 
Leak volumes in excess of 4 percent of the FTIR system volume 
VSS are unacceptable.
    8.3 Detector Linearity. Once an optical configuration is chosen, use 
one of the procedures of sections 8.3.1 through 8.3.3 to verify that the 
detector response is linear. If the detector response is not linear, 
decrease the aperture, or attenuate the infrared beam. After a change in 
the instrument configuration perform a linearity check until it is 
demonstrated that the detector response is linear.
    8.3.1 Vary the power incident on the detector by modifying the 
aperture setting. Measure the background and CTS at three instrument 
aperture settings: (1) at the aperture setting to be used in the 
testing, (2) at one half this aperture and (3) at twice the proposed 
testing aperture. Compare the

[[Page 1108]]

three CTS spectra. CTS band areas shall agree to within the uncertainty 
of the cylinder standard and the RMSD noise in the system. If test 
aperture is the maximum aperture, collect CTS spectrum at maximum 
aperture, then close the aperture to reduce the IR throughput by half. 
Collect a second background and CTS at the smaller aperture setting and 
compare the spectra again.
    8.3.2 Use neutral density filters to attenuate the infrared beam. 
Set up the FTIR system as it will be used in the test measurements. 
Collect a CTS spectrum. Use a neutral density filter to attenuate the 
infrared beam (either immediately after the source or the 
interferometer) to approximately \1/2\ its original intensity. Collect a 
second CTS spectrum. Use another filter to attenuate the infrared beam 
to approximately \1/4\ its original intensity. Collect a third 
background and CTS spectrum. Compare the CTS spectra. CTS band areas 
shall agree to within the uncertainty of the cylinder standard and the 
RMSD noise in the system.
    8.3.3 Observe the single beam instrument response in a frequency 
region where the detector response is known to be zero. Verify that the 
detector response is ``flat'' and equal to zero in these regions.
    8.4 Data Storage Requirements. All field test spectra shall be 
stored on a computer disk and a second backup copy must stored on a 
separate disk. The stored information includes sample interferograms, 
processed absorbance spectra, background interferograms, CTS sample 
interferograms and CTS absorbance spectra. Additionally, documentation 
of all sample conditions, instrument settings, and test records must be 
recorded on hard copy or on computer medium. Table 1 gives a sample 
presentation of documentation.
    8.5 Background Spectrum. Evacuate the gas cell to [le]5 mmHg, and 
fill with dry nitrogen gas to ambient pressure (or purge the cell with 
10 volumes of dry nitrogen). Verify that no significant amounts of 
absorbing species (for example water vapor and CO2) are 
present. Collect a background spectrum, using a signal averaging period 
equal to or greater than the averaging period for the sample spectra. 
Assign a unique file name to the background spectrum. Store two copies 
of the background interferogram and processed single-beam spectrum on 
separate computer disks (one copy is the back-up).
    8.5.1 Interference Spectra. If possible, collect spectra of known 
and suspected major interferences using the same optical system that 
will be used in the field measurements. This can be done on-site or 
earlier. A number of gases, e.g. CO2, SO2, CO, 
NH3, are readily available from cylinder gas suppliers.
    8.5.2 Water vapor spectra can be prepared by the following 
procedure. Fill a sample tube with distilled water. Evacuate above the 
sample and remove dissolved gasses by alternately freezing and thawing 
the water while evacuating. Allow water vapor into the FTIR cell, then 
dilute to atmospheric pressure with nitrogen or dry air. If quantitative 
water spectra are required, follow the reference spectrum procedure for 
neat samples (protocol, section 4.6). Often, interference spectra need 
not be quantitative, but for best results the absorbance must be 
comparable to the interference absorbance in the sample spectra.

                        8.6 Pre-Test Calibrations

    8.6.1 Calibration Transfer Standard. Evacuate the gas cell to [le] 5 
mmHg absolute pressure, and fill the FTIR cell to atmospheric pressure 
with the CTS gas. Alternatively, purge the cell with 10 cell volumes of 
CTS gas. (If purge is used, verify that the CTS concentration in the 
cell is stable by collecting two spectra 2 minutes apart as the CTS gas 
continues to flow. If the absorbance in the second spectrum is no 
greater than in the first, within the uncertainty of the gas standard, 
then this can be used as the CTS spectrum.) Record the spectrum.
    8.6.2 QA Spike. This procedure assumes that the method has been 
validated for at least some of the target analytes at the source. For 
emissions testing perform a QA spike. Use a certified standard, if 
possible, of an analyte, which has been validated at the source. One 
analyte standard can serve as a QA surrogate for other analytes which 
are less reactive or less soluble than the standard. Perform the spike 
procedure of section 9.2 of this method. Record spectra of at least 
three independent (section 3.22 of this method) spiked samples. 
Calculate the spiked component of the analyte concentration. If the 
average spiked concentration is within 0.7 to 1.3 times the expected 
concentration, then proceed with the testing. If applicable, apply the 
correction factor from the Method 301 of this appendix validation test 
(not the result from the QA spike).
    8.7 Sampling. If analyte concentrations vary rapidly with time, 
continuous sampling is preferable using the smallest cell volume, 
fastest sampling rate and fastest spectra collection rate possible. 
Continuous sampling requires the least operator intervention even 
without an automated sampling system. For continuous monitoring at one 
location over long periods, Continuous sampling is preferred. Batch 
sampling and continuous static sampling are used for screening and 
performing test runs of finite duration. Either technique is preferred 
for sampling several locations in a matter of days. Batch sampling gives 
reasonably good time resolution and ensures that each spectrum measures 
a discreet (and unique) sample volume. Continuous static (and 
continuous) sampling provide a very stable background over long periods. 
Like batch sampling, continuous static

[[Page 1109]]

sampling also ensures that each spectrum measures a unique sample 
volume. It is essential that the leak check procedure under vacuum 
(section 8.2 of this method) is passed if the batch sampling procedure 
is used. It is essential that the leak check procedure under positive 
pressure is passed if the continuous static or continuous sampling 
procedures are used. The sampling techniques are described in sections 
8.7.1 through 8.7.2 of this method.
    8.7.1 Batch Sampling. Evacuate the absorbance cell to [le]5 mmHg 
absolute pressure. Fill the cell with exhaust gas to ambient pressure, 
isolate the cell, and record the spectrum. Before taking the next 
sample, evacuate the cell until no spectral evidence of sample 
absorption remains. Repeat this procedure to collect eight spectra of 
separate samples in 1 hour.
    8.7.2 Continuous Static Sampling. Purge the FTIR cell with 10 cell 
volumes of sample gas. Isolate the cell, collect the spectrum of the 
static sample and record the pressure. Before measuring the next sample, 
purge the cell with 10 more cell volumes of sample gas.

                      8.8 Sampling QA and Reporting

    8.8.1 Sample integration times shall be sufficient to achieve the 
required signal-to-noise ratio. Obtain an absorbance spectrum by filling 
the cell with N2. Measure the RMSD in each analytical region in this 
absorbance spectrum. Verify that the number of scans used is sufficient 
to achieve the target MAU.
    8.8.2 Assign a unique file name to each spectrum.
    8.8.3 Store two copies of sample interferograms and processed 
spectra on separate computer disks.
    8.8.4 For each sample spectrum, document the sampling conditions, 
the sampling time (while the cell was being filled), the time the 
spectrum was recorded, the instrumental conditions (path length, 
temperature, pressure, resolution, signal integration time), and the 
spectral file name. Keep a hard copy of these data sheets.
    8.9 Signal Transmittance. While sampling, monitor the signal 
transmittance. If signal transmittance (relative to the background) 
changes by 5 percent or more (absorbance = -.02 to .02) in any 
analytical spectral region, obtain a new background spectrum.
    8.10 Post-test CTS. After the sampling run, record another CTS 
spectrum.
    8.11 Post-test QA
    8.11.1 Inspect the sample spectra immediately after the run to 
verify that the gas matrix composition was close to the expected 
(assumed) gas matrix.
    8.11.2 Verify that the sampling and instrumental parameters were 
appropriate for the conditions encountered. For example, if the moisture 
is much greater than anticipated, it may be necessary to use a shorter 
path length or dilute the sample.
    8.11.3 Compare the pre- and post-test CTS spectra. The peak 
absorbance in pre- and post-test CTS must be [plusmn]5 percent of the 
mean value. See appendix E of the FTIR Protocol.

                           9.0 Quality Control

    Use analyte spiking (sections 8.6.2, 9.2 and 13.0 of this method) to 
verify that the sampling system can transport the analytes from the 
probe to the FTIR system.
    9.1 Spike Materials. Use a certified standard (accurate to [plusmn]2 
percent) of the target analyte, if one can be obtained. If a certified 
standard cannot be obtained, follow the procedures in section 4.6.2.2 of 
the FTIR Protocol.
    9.2 Spiking Procedure. QA spiking (section 8.6.2 of this method) is 
a calibration procedure used before testing. QA spiking involves 
following the spike procedure of sections 9.2.1 through 9.2.3 of this 
method to obtain at least three spiked samples. The analyte 
concentrations in the spiked samples shall be compared to the expected 
spike concentration to verify that the sampling/analytical system is 
working properly. Usually, when QA spiking is used, the method has 
already been validated at a similar source for the analyte in question. 
The QA spike demonstrates that the validated sampling/analytical 
conditions are being duplicated. If the QA spike fails then the 
sampling/analytical system shall be repaired before testing proceeds. 
The method validation procedure (section 13.0 of this method) involves a 
more extensive use of the analyte spike procedure of sections 9.2.1 
through 9.2.3 of this method. Spectra of at least 12 independent spiked 
and 12 independent unspiked samples are recorded. The concentration 
results are analyzed statistically to determine if there is a systematic 
bias in the method for measuring a particular analyte. If there is a 
systematic bias, within the limits allowed by Method 301 of this 
appendix, then a correction factor shall be applied to the analytical 
results. If the systematic bias is greater than the allowed limits, this 
method is not valid and cannot be used.
    9.2.1 Introduce the spike/tracer gas at a constant flow rate of 
[le]10 percent of the total sample flow, when possible.
    Note: Use the rotameter at the end of the sampling train to estimate 
the required spike/tracer gas flow rate.

    Use a flow device, e.g., mass flow meter ( 2 
percent), to monitor the spike flow rate. Record the spike flow rate 
every 10 minutes.
    9.2.2 Determine the response time (RT) of the system by continuously 
collecting spectra of the spiked effluent until the spectrum of the 
spiked component is constant for 5 minutes. The RT is the interval from 
the

[[Page 1110]]

first measurement until the spike becomes constant. Wait for twice the 
duration of the RT, then collect spectra of two independent spiked gas 
samples. Duplicate analyses of the spiked concentration shall be within 
5 percent of the mean of the two measurements.
    9.2.3 Calculate the dilution ratio using the tracer gas as follows: 
where:
[GRAPHIC] [TIFF OMITTED] TR14JN99.005

Where:

[GRAPHIC] [TIFF OMITTED] TR14JN99.006

DF=Dilution factor of the spike gas; this value shall be [ge]10.
SF6(dir)=SF6 (or tracer gas) concentration 
          measured directly in undiluted spike gas.
SF6(spk)=Diluted SF6 (or tracer gas) concentration 
          measured in a spiked sample.
Spikedir=Concentration of the analyte in the spike standard 
          measured by filling the FTIR cell directly.
CS=Expected concentration of the spiked samples.
Unspike=Native concentration of analytes in unspiked samples.

                  10.0 Calibration and Standardization

    10.1 Signal-to-Noise Ratio (S/N). The RMSD in the noise must be less 
than one tenth of the minimum analyte peak absorbance in each analytical 
region. For example if the minimum peak absorbance is 0.01 at the 
required DL, then RMSD measured over the entire analytical region must 
be [le]0.001.
    10.2 Absorbance Path length. Verify the absorbance path length by 
comparing reference CTS spectra to test CTS spectra. See appendix E of 
the FTIR Protocol.
    10.3 Instrument Resolution. Measure the line width of appropriate 
test CTS band(s) to verify instrument resolution. Alternatively, compare 
CTS spectra to a reference CTS spectrum, if available, measured at the 
nominal resolution.
    10.4 Apodization Function.In transforming the sample interferograms 
to absorbance spectra use the same apodization function that was used in 
transforming the reference spectra.
    10.5 FTIR Cell Volume. Evacuate the cell to [le]5 mmHg. Measure the 
initial absolute temperature (Ti) and absolute pressure 
(Pi). Connect a wet test meter (or a calibrated dry gas 
meter), and slowly draw room air into the cell. Measure the meter volume 
(Vm), meter absolute temperature (Tm), and meter 
absolute pressure (Pm); and the cell final absolute 
temperature (Tf) and absolute pressure (Pf). 
Calculate the FTIR cell volume VSS, including that of the connecting 
tubing, as follows:
[GRAPHIC] [TIFF OMITTED] TR14JN99.007

                   11.0 Data Analysis and Calculations

    Analyte concentrations shall be measured using reference spectra 
from the EPA FTIR spectral library. When EPA library spectra are not 
available, the procedures in section 4.6 of the Protocol shall be 
followed to prepare reference spectra of all the target analytes.
    11.1 Spectral De-resolution. Reference spectra can be converted to 
lower resolution standard spectra (section 3.3 of this method) by 
truncating the original reference sample and background interferograms. 
Appendix K of the FTIR Protocol gives specific deresolution procedures. 
Deresolved spectra shall be transformed using the same apodization 
function and level of zero filling as the sample spectra. Additionally, 
pre-test FTIR protocol calculations (e.g., FRU, MAU, FCU) shall be 
performed using the de-resolved standard spectra.
    11.2 Data Analysis. Various analytical programs are available for 
relating sample absorbance to a concentration standard. Calculated 
concentrations shall be verified by analyzing residual baselines after 
mathematically subtracting scaled reference spectra from the sample 
spectra. A full description of the data analysis and calculations is 
contained in the FTIR Protocol (sections 4.0, 5.0, 6.0 and appendices). 
Correct the calculated concentrations in the sample spectra for 
differences in absorption path length and temperature between the 
reference and sample spectra using equation 6,
[GRAPHIC] [TIFF OMITTED] TR14JN99.008

Where:

Ccorr=Concentration, corrected for path length.

[[Page 1111]]

Ccalc=Concentration, initial calculation (output of the 
          analytical program designed for the compound).
Lr=Reference spectra path length.
Ls=Sample spectra path length.
Ts=Absolute temperature of the sample gas, K.
Tr=Absolute gas temperature of reference spectra, K.
Ps=Sample cell pressure.
Pr=Reference spectrum sample pressure.

                         12.0 Method Performance

    12.1 Spectral Quality. Refer to the FTIR Protocol appendices for 
analytical requirements, evaluation of data quality, and analysis of 
uncertainty.
    12.2 Sampling QA/QC. The analyte spike procedure of section 9 of 
this method, the QA spike of section 8.6.2 of this method, and the 
validation procedure of section 13 of this method are used to evaluate 
the performance of the sampling system and to quantify sampling system 
effects, if any, on the measured concentrations. This method is self-
validating provided that the results meet the performance requirement of 
the QA spike in sections 9.0 and 8.6.2 of this method and results from a 
previous method validation study support the use of this method in the 
application. Several factors can contribute to uncertainty in the 
measurement of spiked samples. Factors which can be controlled to 
provide better accuracy in the spiking procedure are listed in sections 
12.2.1 through 12.2.4 of this method.
    12.2.1 Flow meter. An accurate mass flow meter is accurate to 
[plusmn]1 percent of its span. If a flow of 1 L/min is monitored with 
such a MFM, which is calibrated in the range of 0-5 L/min, the flow 
measurement has an uncertainty of 5 percent. This may be improved by re-
calibrating the meter at the specific flow rate to be used.
    12.2.2 Calibration gas. Usually the calibration standard is 
certified to within [plusmn] 2 percent. With reactive analytes, such as 
HCl, the certified accuracy in a commercially available standard may be 
no better than [plusmn] 5 percent.
    12.2.3 Temperature. Temperature measurements of the cell shall be 
quite accurate. If practical, it is preferable to measure sample 
temperature directly, by inserting a thermocouple into the cell chamber 
instead of monitoring the cell outer wall temperature.
    12.2.4 Pressure. Accuracy depends on the accuracy of the barometer, 
but fluctuations in pressure throughout a day may be as much as 2.5 
percent due to weather variations.

                    13.0 Method Validation Procedure

    This validation procedure, which is based on EPA Method 301 (40 CFR 
part 63, appendix (A), may be used to validate this method for the 
analytes in a gas matrix. Validation at one source may also apply to 
another type of source, if it can be shown that the exhaust gas 
characteristics are similar at both sources.
    13.1 Section 5.3 of Method 301 (40 CFR part 63, appendix A), the 
Analyte Spike procedure, is used with these modifications. The 
statistical analysis of the results follows section 6.3 of EPA Method 
301. Section 3 of this method defines terms that are not defined in 
Method 301.
    13.1.1 The analyte spike is performed dynamically. This means the 
spike flow is continuous and constant as spiked samples are measured.
    13.1.2 The spike gas is introduced at the back of the sample probe.
    13.1.3 Spiked effluent is carried through all sampling components 
downstream of the probe.
    13.1.4 A single FTIR system (or more) may be used to collect and 
analyze spectra (not quadruplicate integrated sampling trains).
    13.1.5 All of the validation measurements are performed sequentially 
in a single ``run'' (section 3.26 of this method).
    13.1.6 The measurements analyzed statistically are each independent 
(section 3.22 of this method).
    13.1.7 A validation data set can consist of more than 12 spiked and 
12 unspiked measurements.
    13.2 Batch Sampling. The procedure in sections 13.2.1 through 13.2.2 
may be used for stable processes. If process emissions are highly 
variable, the procedure in section 13.2.3 shall be used.
    13.2.1 With a single FTIR instrument and sampling system, begin by 
collecting spectra of two unspiked samples. Introduce the spike flow 
into the sampling system and allow 10 cell volumes to purge the sampling 
system and FTIR cell. Collect spectra of two spiked samples. Turn off 
the spike and allow 10 cell volumes of unspiked sample to purge the FTIR 
cell. Repeat this procedure until the 24 (or more) samples are 
collected.
    13.2.2 In batch sampling, collect spectra of 24 distinct samples. 
(Each distinct sample consists of filling the cell to ambient pressure 
after the cell has been evacuated.)
    13.2.3 Alternatively, a separate probe assembly, line, and sample 
pump can be used for spiked sample. Verify and document that sampling 
conditions are the same in both the spiked and the unspiked sampling 
systems. This can be done by wrapping both sample lines in the same 
heated bundle. Keep the same flow rate in both sample lines. Measure 
samples in sequence in pairs. After two spiked samples are measured, 
evacuate the FTIR cell, and turn the manifold valve so that spiked 
sample flows to the FTIR cell. Allow the connecting line from the 
manifold to the FTIR cell to purge thoroughly (the

[[Page 1112]]

time depends on the line length and flow rate). Collect a pair of spiked 
samples. Repeat the procedure until at least 24 measurements are 
completed.
    13.3 Simultaneous Measurements With Two FTIR Systems. If unspiked 
effluent concentrations of the target analyte(s) vary significantly with 
time, it may be desirable to perform synchronized measurements of spiked 
and unspiked sample. Use two FTIR systems, each with its own cell and 
sampling system to perform simultaneous spiked and unspiked 
measurements. The optical configurations shall be similar, if possible. 
The sampling configurations shall be the same. One sampling system and 
FTIR analyzer shall be used to measure spiked effluent. The other 
sampling system and FTIR analyzer shall be used to measure unspiked flue 
gas. Both systems shall use the same sampling procedure (i.e., batch or 
continuous).
    13.3.1 If batch sampling is used, synchronize the cell evacuation, 
cell filling, and collection of spectra. Fill both cells at the same 
rate (in cell volumes per unit time).
    13.3.2 If continuous sampling is used, adjust the sample flow 
through each gas cell so that the same number of cell volumes pass 
through each cell in a given time (i.e. TC1 = 
TC2).
    13.4 Statistical Treatment. The statistical procedure of EPA Method 
301 of this appendix, section 6.3 is used to evaluate the bias and 
precision. For FTIR testing a validation ``run'' is defined as spectra 
of 24 independent samples, 12 of which are spiked with the analyte(s) 
and 12 of which are not spiked.
    13.4.1 Bias. Determine the bias (defined by EPA Method 301 of this 
appendix, section 6.3.2) using equation 7:
[GRAPHIC] [TIFF OMITTED] TR14JN99.009

Where:

B = Bias at spike level.
Sm = Mean concentration of the analyte spiked samples.
CS = Expected concentration of the spiked samples.

    13.4.2 Correction Factor. Use section 6.3.2.2 of Method 301 of this 
appendix to evaluate the statistical significance of the bias. If it is 
determined that the bias is significant, then use section 6.3.3 of 
Method 301 to calculate a correction factor (CF). Analytical results of 
the test method are multiplied by the correction factor, if 0.7 [le] CF 
[le] 1.3. If is determined that the bias is significant and CF 
 [plusmn] 30 percent, then the test method is considered to 
``not valid.''
    13.4.3 If measurements do not pass validation, evaluate the sampling 
system, instrument configuration, and analytical system to determine if 
improper set-up or a malfunction was the cause. If so, repair the system 
and repeat the validation.

                       14.0 Pollution Prevention.

    The extracted sample gas is vented outside the enclosure containing 
the FTIR system and gas manifold after the analysis. In typical method 
applications the vented sample volume is a small fraction of the source 
volumetric flow and its composition is identical to that emitted from 
the source. When analyte spiking is used, spiked pollutants are vented 
with the extracted sample gas. Approximately 1.6 x 10-\4\ to 3.2 x 10-
\4\ lbs of a single HAP may be vented to the atmosphere in a typical 
validation run of 3 hours. (This assumes a molar mass of 50 to 100 g, 
spike rate of 1.0 L/min, and a standard concentration of 100 ppm). 
Minimize emissions by keeping the spike flow off when not in use.

                         15.0 Waste Management.

    Small volumes of laboratory gas standards can be vented through a 
laboratory hood. Neat samples must be packed and disposed according to 
applicable regulations. Surplus materials may be returned to supplier 
for disposal.

Addendum to Test Method 320--Protocol for the Use of Extractive Fourier 
   Transform Infrared (FTIR) Spectrometry for the Analyses of Gaseous 
                    Emissions from Stationary Sources

                            1.0 Introduction

    The purpose of this addendum is to set general guidelines for the 
use of modern FTIR spectroscopic methods for the analysis of gas samples 
extracted from the effluent of stationary emission sources. This 
addendum outlines techniques for developing and evaluating such methods 
and sets basic requirements for reporting and quality assurance 
procedures.

                            1.1 Nomenclature

    1.1.1 Appendix A to this addendum lists definitions of the symbols 
and terms used in this Protocol, many of which have been taken directly 
from American Society for Testing and Materials (ASTM) publication E 
131-90a, entitled ``Terminology Relating to Molecular Spectroscopy.''
    1.1.2 Except in the case of background spectra or where otherwise 
noted, the term ``spectrum'' refers to a double-beam spectrum in units 
of absorbance vs. wavenumber (cm-1).
    1.1.3 The term ``Study'' in this addendum refers to a publication 
that has been subjected to EPA- or peer-review.

               2.0 Applicability and Analytical Principle

    2.1 Applicability. This Protocol applies to the determination of 
compound-specific concentrations in single- and multiple-component gas 
phase samples using double-beam absorption spectroscopy in the mid-
infrared band. It does not specifically address other FTIR applications, 
such as single-beam spectroscopy, analysis of open-path (non-enclosed) 
samples, and continuous measurement techniques. If multiple 
spectrometers, absorption cells, or instrumental linewidths are used in 
such analyses, each distinct operational configuration of the system 
must be evaluated separately according to this Protocol.

                        2.2 Analytical Principle

    2.2.1 In the mid-infrared band, most molecules exhibit 
characteristic gas phase absorption spectra that may be recorded by FTIR 
systems. Such systems consist of a source of mid-infrared radiation, an 
interferometer, an enclosed sample cell of known absorption pathlength, 
an infrared detector, optical elements for the transfer of infrared 
radiation between components, and gas flow

[[Page 1115]]

control and measurement components. Adjunct and integral computer 
systems are used for controlling the instrument, processing the signal, 
and for performing both Fourier transforms and quantitative analyses of 
spectral data.
    2.2.2 The absorption spectra of pure gases and of mixtures of gases 
are described by a linear absorbance theory referred to as Beer's Law. 
Using this law, modern FTIR systems use computerized analytical programs 
to quantify compounds by comparing the absorption spectra of known 
(reference) gas samples to the absorption spectrum of the sample gas. 
Some standard mathematical techniques used for comparisons are classical 
least squares, inverse least squares, cross-correlation, factor 
analysis, and partial least squares. Reference A describes several of 
these techniques, as well as additional techniques, such as 
differentiation methods, linear baseline corrections, and non-linear 
absorbance corrections.

             3.0 General Principles of Protocol Requirements

    The characteristics that distinguish FTIR systems from gas analyzers 
used in instrumental gas analysis methods (e.g., Methods 6C and 7E of 
appendix A to part 60 of this chapter) are: (1) Computers are necessary 
to obtain and analyze data; (2) chemical concentrations can be 
quantified using previously recorded infrared reference spectra; and (3) 
analytical assumptions and results, including possible effects of 
interfering compounds, can be evaluated after the quantitative analysis. 
The following general principles and requirements of this Protocol are 
based on these characteristics.
    3.1 Verifiability and Reproducibility of Results. Store all data and 
document data analysis techniques sufficient to allow an independent 
agent to reproduce the analytical results from the raw interferometric 
data.
    3.2 Transfer of Reference Spectra. To determine whether reference 
spectra recorded under one set of conditions (e.g., optical bench, 
instrumental linewidth, absorption pathlength, detector performance, 
pressure, and temperature) can be used to analyze sample spectra taken 
under a different set of conditions, quantitatively compare 
``calibration transfer standards'' (CTS) and reference spectra as 
described in this Protocol.
    Note: The CTS may, but need not, include analytes of interest). To 
effect this, record the absorption spectra of the CTS (a) immediately 
before and immediately after recording reference spectra and (b) 
immediately after recording sample spectra.
    3.3 Evaluation of FTIR Analyses. The applicability, accuracy, and 
precision of FTIR measurements are influenced by a number of 
interrelated factors, which may be divided into two classes:
    3.3.1 Sample-Independent Factors. Examples are system configuration 
and performance (e.g., detector sensitivity and infrared source output), 
quality and applicability of reference absorption spectra, and type of 
mathematical analyses of the spectra. These factors define the 
fundamental limitations of FTIR measurements for a given system 
configuration. These limitations may be estimated from evaluations of 
the system before samples are available. For example, the detection 
limit for the absorbing compound under a given set of conditions may be 
estimated from the system noise level and the strength of a particular 
absorption band. Similarly, the accuracy of measurements may be 
estimated from the analysis of the reference spectra.
    3.3.2 Sample-Dependent Factors. Examples are spectral interferants 
(e.g., water vapor and CO2) or the overlap of spectral 
features of different compounds and contamination deposits on reflective 
surfaces or transmitting windows. To maximize the effectiveness of the 
mathematical techniques used in spectral analysis, identification of 
interferants (a standard initial step) and analysis of samples (includes 
effect of other analytical errors) are necessary. Thus, the Protocol 
requires post-analysis calculation of measurement concentration 
uncertainties for the detection of these potential sources of 
measurement error.

                4.0 Pre-Test Preparations and Evaluations

    Before testing, demonstrate the suitability of FTIR spectrometry for 
the desired application according to the procedures of this section.
    4.1 Identify Test Requirements. Identify and record the test 
requirements described in sections 4.1.1 through 4.1.4 of this addendum. 
These values set the desired or required goals of the proposed analysis; 
the description of methods for determining whether these goals are 
actually met during the analysis comprises the majority of this 
Protocol.
    4.1.1 Analytes (specific chemical species) of interest. Label the 
analytes from i = 1 to I.
    4.1.2 Analytical uncertainty limit (AUi). The 
AUi is the maximum permissible fractional uncertainty of 
analysis for the ith analyte concentration, expressed as a 
fraction of the analyte concentration in the sample.
    4.1.3 Required detection limit for each analyte (DLi, 
ppm). The detection limit is the lowest concentration of an analyte for 
which its overall fractional uncertainty (OFUi) is required 
to be less than its analytical uncertainty limit (AUi).
    4.1.4 Maximum expected concentration of each analyte 
(CMAXi, ppm).
    4.2 Identify Potential Interferants. Considering the chemistry of 
the process or results of previous studies, identify potential

[[Page 1116]]

interferants, i.e., the major effluent constituents and any relatively 
minor effluent constituents that possess either strong absorption 
characteristics or strong structural similarities to any analyte of 
interest. Label them 1 through Nj, where the subscript ``j'' 
pertains to potential interferants. Estimate the concentrations of these 
compounds in the effluent (CPOTj, ppm).
    4.3 Select and Evaluate the Sampling System. Considering the source, 
e.g., temperature and pressure profiles, moisture content, analyte 
characteristics, and particulate concentration), select the equipment 
for extracting gas samples. Recommended are a particulate filter, 
heating system to maintain sample temperature above the dew point for 
all sample constituents at all points within the sampling system 
(including the filter), and sample conditioning system (e.g., coolers, 
water-permeable membranes that remove water or other compounds from the 
sample, and dilution devices) to remove spectral interferants or to 
protect the sampling and analytical components. Determine the minimum 
absolute sample system pressure (Pmin, mmHg) and the infrared 
absorption cell volume (VSS, liter). Select the techniques 
and/or equipment for the measurement of sample pressures and 
temperatures.
    4.4 Select Spectroscopic System. Select a spectroscopic 
configuration for the application. Approximate the absorption pathlength 
(LS', meter), sample pressure (PS', kPa), absolute 
sample temperature TS', and signal integration period 
(tSS, seconds) for the analysis. Specify the nominal minimum 
instrumental linewidth (MIL) of the system. Verify that the fractional 
error at the approximate values PS' and TS' is 
less than one half the smallest value AUi (see section 4.1.2 
of this addendum).
    4.5 Select Calibration Transfer Standards (CTS's). Select CTS's that 
meet the criteria listed in sections 4.5.1, 4.5.2, and 4.5.3 of this 
addendum.
    Note: It may be necessary to choose preliminary analytical regions 
(see section 4.7 of this addendum), identify the minimum analyte 
linewidths, or estimate the system noise level (see section 4.12 of this 
addendum) before selecting the CTS. More than one compound may be needed 
to meet the criteria; if so, obtain separate cylinders for each 
compound.
    4.5.1 The central wavenumber position of each analytical region 
shall lie within 25 percent of the wavenumber position of at least one 
CTS absorption band.
    4.5.2 The absorption bands in section 4.5.1 of this addendum shall 
exhibit peak absorbances greater than ten times the value 
RMSEST (see section 4.12 of this addendum) but less than 1.5 
absorbance units.
    4.5.3 At least one absorption CTS band within the operating range of 
the FTIR instrument shall have an instrument-independent linewidth no 
greater than the narrowest analyte absorption band. Perform and document 
measurements or cite Studies to determine analyte and CTS compound 
linewidths.
    4.5.4 For each analytical region, specify the upper and lower 
wavenumber positions (FFUm and FFLm, respectively) 
that bracket the CTS absorption band or bands for the associated 
analytical region. Specify the wavenumber range, FNU to FNL, containing 
the absorption band that meets the criterion of section 4.5.3 of this 
addendum.
    4.5.5 Associate, whenever possible, a single set of CTS gas 
cylinders with a set of reference spectra. Replacement CTS gas cylinders 
shall contain the same compounds at concentrations within 5 percent of 
that of the original CTS cylinders; the entire absorption spectra (not 
individual spectral segments) of the replacement gas shall be scaled by 
a factor between 0.95 and 1.05 to match the original CTS spectra.

                      4.6 Prepare Reference Spectra

    Note: Reference spectra are available in a permanent soft copy from 
the EPA spectral library on the EMTIC (Emission Measurement Technical 
Information Center) computer bulletin board; they may be used if 
applicable.
    4.6.1 Select the reference absorption pathlength (LR) of 
the cell.
    4.6.2 Obtain or prepare a set of chemical standards for each 
analyte, potential and known spectral interferants, and CTS. Select the 
concentrations of the chemical standards to correspond to the top of the 
desired range.
    4.6.2.1 Commercially-Prepared Chemical Standards. Chemical standards 
for many compounds may be obtained from independent sources, such as a 
specialty gas manufacturer, chemical company, or commercial laboratory. 
These standards (accurate to within [plusmn]2 percent) shall be prepared 
according to EPA Traceability Protocol (see Reference D) or shall be 
traceable to NIST standards. Obtain from the supplier an estimate of the 
stability of the analyte concentration. Obtain and follow all of the 
supplier's recommendations for recertifying the analyte concentration.
    4.6.2.2 Self-Prepared Chemical Standards. Chemical standards may be 
prepared by diluting certified commercially prepared chemical gases or 
pure analytes with ultra-pure carrier (UPC) grade nitrogen according to 
the barometric and volumetric techniques generally described in 
Reference A, section A4.6.
    4.6.3 Record a set of the absorption spectra of the CTS {R1[squ], 
then a set of the reference spectra at two or more concentrations in 
duplicate over the desired range (the top of the range must be less than 
10 times that of the bottom), followed by a second set

[[Page 1117]]

of CTS spectra {R2[squ]. (If self-prepared standards are used, see 
section 4.6.5 of this addendum before disposing of any of the 
standards.) The maximum accepted standard concentration-pathlength 
product (ASCPP) for each compound shall be higher than the maximum 
estimated concentration-pathlength products for both analytes and known 
interferants in the effluent gas. For each analyte, the minimum ASCPP 
shall be no greater than ten times the concentration-pathlength product 
of that analyte at its required detection limit.
    4.6.4 Permanently store the background and interferograms in 
digitized form. Document details of the mathematical process for 
generating the spectra from these interferograms. Record the sample 
pressure (PR), sample temperature (TR), reference 
absorption pathlength (LR), and interferogram signal 
integration period (tSR). Signal integration periods for the 
background interferograms shall be [ge]tSR. Values of 
PR, LR, and tSR shall not deviate by 
more than [plusmn]1 percent from the time of recording [R1] to that of 
recording [R2].
    4.6.5 If self-prepared chemical standards are employed and spectra 
of only two concentrations are recorded for one or more compounds, 
verify the accuracy of the dilution technique by analyzing the prepared 
standards for those compounds with a secondary (non-FTIR) technique in 
accordance with sections 4.6.5.1 through 4.6.5.4 of this addendum.
    4.6.5.1 Record the response of the secondary technique to each of 
the four standards prepared.
    4.6.5.2 Perform a linear regression of the response values 
(dependant variable) versus the accepted standard concentration (ASC) 
values (independent variable), with the regression constrained to pass 
through the zero-response, zero ASC point.
    4.6.5.3 Calculate the average fractional difference between the 
actual response values and the regression-predicted values (those 
calculated from the regression line using the four ASC values as the 
independent variable).
    4.6.5.4 If the average fractional difference value calculated in 
section 4.6.5.3 of this addendum is larger for any compound than the 
corresponding AUi, the dilution technique is not sufficiently 
accurate and the reference spectra prepared are not valid for the 
analysis.
    4.7 Select Analytical Regions. Using the general considerations in 
section 7 of Reference A and the spectral characteristics of the 
analytes and interferants, select the analytical regions for the 
application. Label them m = 1 to M. Specify the lower, center and upper 
wavenumber positions of each analytical region (FLm, 
FCm, and FUm, respectively). Specify the analytes 
and interferants which exhibit absorption in each region.
    4.8 Determine Fractional Reproducibility Uncertainties. Using 
appendix E of this addendum, calculate the fractional reproducibility 
uncertainty for each analyte (FRUi) from a comparison of [R1] 
and [R2]. If FRUi  AUi for any analyte, 
the reference spectra generated in accordance with section 4.6 of this 
addendum are not valid for the application.
    4.9 Identify Known Interferants. Using appendix B of this addendum, 
determine which potential interferants affect the analyte concentration 
determinations. Relabel these potential interferant as ``known'' 
interferants, and designate these compounds from k = 1 to K. Appendix B 
to this addendum also provides criteria for determining whether the 
selected analytical regions are suitable.

              4.10 Prepare Computerized Analytical Programs

    4.10.1 Choose or devise mathematical techniques (e.g, classical 
least squares, inverse least squares, cross-correlation, and factor 
analysis) based on equation 4 of Reference A that are appropriate for 
analyzing spectral data by comparison with reference spectra.
    4.10.2 Following the general recommendations of Reference A, prepare 
a computer program or set of programs that analyzes all of the analytes 
and known interferants, based on the selected analytical regions 
(section 4.7 of this addendum) and the prepared reference spectra 
(section 4.6 of this addendum). Specify the baseline correction 
technique (e.g., determining the slope and intercept of a linear 
baseline contribution in each analytical region) for each analytical 
region, including all relevant wavenumber positions.
    4.10.3 Use programs that provide as output [at the reference 
absorption pathlength (LR), reference gas temperature 
(TR), and reference gas pressure (PR)] the analyte 
concentrations, the known interferant concentrations, and the baseline 
slope and intercept values. If the sample absorption pathlength 
(LS), sample gas temperature (TS), or sample gas 
pressure (PS) during the actual sample analyses differ from 
LR, TR, and PR, use a program or set of 
programs that applies multiplicative corrections to the derived 
concentrations to account for these variations, and that provides as 
output both the corrected and uncorrected values. Include in the report 
of the analysis (see section 7.0 of this addendum) the details of any 
transformations applied to the original reference spectra (e.g., 
differentiation), in such a fashion that all analytical results may be 
verified by an independent agent from the reference spectra and data 
spectra alone.
    4.11 Determine the Fractional Calibration Uncertainty. Calculate the 
fractional calibration uncertainty for each analyte (FCUi) according to 
appendix F of this addendum, and compare these values to the fractional 
uncertainty limits (AUi; see section 4.1.2 of this

[[Page 1118]]

addendum). If FCUi AUi, either the 
reference spectra or analytical programs for that analyte are 
unsuitable.
    4.12 Verify System Configuration Suitability. Using appendix C of 
this addendum, measure or obtain estimates of the noise level 
(RMSEST, absorbance) of the FTIR system. Alternatively, 
construct the complete spectrometer system and determine the values 
RMSSm using appendix G of this addendum. Estimate the minimum 
measurement uncertainty for each analyte (MAUi, ppm) and 
known interferant (MIUk, ppm) using appendix D of this 
addendum. Verify that (a) MAUi < 
(AUi)(DLi), FRUi < AUi, and FCUi < 
AUi for each analyte and that (b) the CTS chosen meets the 
requirements listed in sections 4.5.1 through 4.5.5 of this addendum.

                   5.0 Sampling and Analysis Procedure

    5.1 Analysis System Assembly and Leak-Test. Assemble the analysis 
system. Allow sufficient time for all system components to reach the 
desired temperature. Then, determine the leak-rate (LR) and 
leak volume (VL), where VL=LR 
tSS. Leak volumes shall be [le]4 percent of VSS.
    5.2 Verify Instrumental Performance. Measure the noise level of the 
system in each analytical region using the procedure of appendix G of 
this addendum. If any noise level is higher than that estimated for the 
system in section 4.12 of this addendum, repeat the calculations of 
appendix D of this addendum and verify that the requirements of section 
4.12 of this addendum are met; if they are not, adjust or repair the 
instrument and repeat this section.

             5.3 Determine the Sample Absorption Pathlength

    Record a background spectrum. Then, fill the absorption cell with 
CTS at the pressure PR and record a set of CTS spectra [R3]. 
Store the background and unscaled CTS single beam interferograms and 
spectra. Using appendix H of this addendum, calculate the sample 
absorption pathlength (LS) for each analytical region. The 
values LS shall not differ from the approximated sample 
pathlength LS' (see section 4.4 of this addendum) by more 
than 5 percent.
    5.4 Record Sample Spectrum. Connect the sample line to the source. 
Either evacuate the absorption cell to an absolute pressure below 5 mmHg 
before extracting a sample from the effluent stream into the absorption 
cell, or pump at least ten cell volumes of sample through the cell 
before obtaining a sample. Record the sample pressure PS. 
Generate the absorbance spectrum of the sample. Store the background and 
sample single beam interferograms, and document the process by which the 
absorbance spectra are generated from these data. (If necessary, apply 
the spectral transformations developed in section 5.6.2 of this 
addendum). The resulting sample spectrum is referred to below as 
SS.

    Note: Multiple sample spectra may be recorded according to the 
procedures of section 5.4 of this addendum before performing sections 
5.5 and 5.6 of this addendum.

    5.5 Quantify Analyte Concentrations. Calculate the unscaled analyte 
concentrations RUAi and unscaled interferant concentrations 
RUIK using the programs developed in section 4 of this 
addendum. To correct for pathlength and pressure variations between the 
reference and sample spectra, calculate the scaling factor, 
RLPS using equation A.1,

Calculate the final analyte and interferant concentrations 
RSAi and RSIk using equations A.2 and A.3,
[GRAPHIC] [TIFF OMITTED] TR14JN99.013

[GRAPHIC] [TIFF OMITTED] TR14JN99.014

    5.6 Determine Fractional Analysis Uncertainty. Fill the absorption 
cell with CTS at the pressure PS. Record a set of CTS spectra 
[R4]. Store the background and CTS single beam interferograms. Using 
appendix H of this addendum, calculate the fractional analysis 
uncertainty (FAU) for each analytical region. If the FAU indicated for 
any analytical region is greater than the required accuracy requirements 
determined in sections 4.1.1 through 4.1.4 of this addendum, then 
comparisons to previously recorded reference spectra are invalid in that 
analytical region, and the analyst shall perform one or both of the 
procedures of sections 5.6.1 through 5.6.2 of this addendum.
    5.6.1 Perform instrumental checks and adjust the instrument to 
restore its performance to acceptable levels. If adjustments are made, 
repeat sections 5.3, 5.4 (except for the recording of a sample 
spectrum), and 5.5 of this addendum to demonstrate that acceptable 
uncertainties are obtained in all analytical regions.
    5.6.2 Apply appropriate mathematical transformations (e.g., 
frequency shifting, zero-filling, apodization, smoothing) to the spectra 
(or to the interferograms upon which the spectra are based) generated 
during the performance of the procedures of section 5.3 of this 
addendum. Document these transformations and their reproducibility. Do 
not apply multiplicative scaling of the spectra, or any set of 
transformations that is mathematically equivalent to multiplicative 
scaling. Different transformations may be applied to different 
analytical regions. Frequency shifts shall be less than one-half the 
minimum instrumental linewidth, and must be applied to all spectral data 
points in an

[[Page 1119]]

analytical region. The mathematical transformations may be retained for 
the analysis if they are also applied to the appropriate analytical 
regions of all sample spectra recorded, and if all original sample 
spectra are digitally stored. Repeat sections 5.3, 5.4 (except the 
recording of a sample spectrum), and 5.5 of this addendum to demonstrate 
that these transformations lead to acceptable calculated concentration 
uncertainties in all analytical regions.

                      6.0 Post-Analysis Evaluations

    Estimate the overall accuracy of the analyses performed in 
accordance with sections 5.1 through 5.6 of this addendum using the 
procedures of sections 6.1 through 6.3 of this addendum.
    6.1 Qualitatively Confirm the Assumed Matrix. Examine each 
analytical region of the sample spectrum for spectral evidence of 
unexpected or unidentified interferants. If found, identify the 
interfering compounds (see Reference C for guidance) and add them to the 
list of known interferants. Repeat the procedures of section 4 of this 
addendum to include the interferants in the uncertainty calculations and 
analysis procedures. Verify that the MAU and FCU values do not increase 
beyond acceptable levels for the application requirements. Re-calculate 
the analyte concentrations (section 5.5 of this addendum) in the 
affected analytical regions.
    6.2 Quantitatively Evaluate Fractional Model Uncertainty (FMU). 
Perform the procedures of either section 6.2.1 or 6.2.2 of this 
addendum:
    6.2.1 Using appendix I of this addendum, determine the fractional 
model error (FMU) for each analyte.
    6.2.2 Provide statistically determined uncertainties FMU for each 
analyte which are equivalent to two standard deviations at the 95 
percent confidence level. Such determinations, if employed, must be 
based on mathematical examinations of the pertinent sample spectra (not 
the reference spectra alone). Include in the report of the analysis (see 
section 7.0 of this addendum) a complete description of the 
determination of the concentration uncertainties.
    6.3 Estimate Overall Concentration Uncertainty (OCU). Using appendix 
J of this addendum, determine the overall concentration uncertainty 
(OCU) for each analyte. If the OCU is larger than the required accuracy 
for any analyte, repeat sections 4 and 6 of this addendum.

                       7.0 Reporting Requirements

[Documentation pertaining to virtually all the procedures of sections 4, 
5, and 6 will be required. Software copies of reference spectra and 
sample spectra will be retained for some minimum time following the 
actual testing.]

 Appendix A to Addendum to Method 320--Definitions of Terms and Symbols

    A.1 Definitions of Terms. All terms used in this method that are not 
defined below have the meaning given to them in the CAA and in subpart A 
of this part.
    Absorption band means a contiguous wavenumber region of a spectrum

unit quantity of sample. The unit ``ppm'' (number, or mole, basis) is 
recommended.
    Concentration-pathlength product means the mathematical product of 
concentration of the species and absorption pathlength. For reference 
spectra, this is a known quantity; for sample spectra, it is the

absorbance or of any function of absorbance with respect to wavelength 
or any function of wavelength.

    Note: The term ``double-beam'' is used elsewhere to denote a 
spectrum in which the sample and background interferograms are collected 
simultaneously along physically distinct absorption paths. Here, the 
term denotes a spectrum in which the sample and background 
interferograms are collected at different times along the same 
absorption path.

in units of wavenumbers (cm-1).
    Mid-infrared means the region of the electromagnetic spectrum from

representing the detector response vs. wavenumber.

    Note: The term ``single-beam'' is used elsewhere to denote any 
spectrum in which the sample and background interferograms are recorded 
on the same physical absorption path; such usage differentiates such 
spectra from those generated using interferograms recorded along two 
physically distinct absorption paths (see ``double-beam spectrum'' 
above). Here, the term applies (for example) to the two spectra used 
directly in the calculation of transmission and absorbance spectra of a 
sample.

spectroscopy by forming the ratio of the single-beam sample and 
background spectra.

 Appendix B to Addendum to Method 320--Identifying Spectral Interferants

                               B.1 General

    B.1.1 Assume a fixed absorption pathlength equal to the value 
LS'.
    B.1.2 Use band area calculations to compare the relative absorption 
strengths of the analytes and potential interferants. In the 
mth analytical region (FLm to FUm), use 
either rectangular or trapezoidal approximations to determine the band 
areas described below (see Reference A, sections A.3.1 through A.3.3). 
Document any baseline corrections applied to the spectra.
    B.1.3 Use the average total absorbance of the analytes and potential 
interferants in each analytical region to determine whether the 
analytical region is suitable for analyte concentration determinations.

    Note: The average absorbance in an analytical region is the band 
area divided by the width of the analytical region in wavenumbers. The 
average total absorbance in an analytical region is the sum of the 
average absorbances of all analytes and potential interferants.

                            B.2 Calculations

    B.2.1 Prepare spectral representations of each analyte at the 
concentration CLi = (DLi)(AUi), where 
DLi is the required detection limit and AUi is the 
maximum permissible analytical uncertainty. For the mth 
analytical region, calculate the band area (AAIim) and 
average absorbance (AAVim) from these scaled analyte spectra.
    B.2.2 Prepare spectral representations of each potential interferant 
at its expected concentration (CPOTj). For the mth 
analytical region, calculate the band area (IAIjm) and 
average absorbance (IAVjm) from these scaled potential 
interferant spectra.
    B.2.3 Repeat the calculation for each analytical region, and record 
the band area results in matrix form as indicated in Figure B.1.
    B.2.4 If the band area of any potential interferant in an analytical 
region is greater than the one-half the band area of any analyte (i.e., 
IAIjm  0.5 AAIim for any pair ij

each analytical region and record the values in the last row of the 
matrix described in Figure B.2. Any analytical region where 
AVTm  2.0 is unsuitable.

      Appendix C to Addendum to Method 320--Estimating Noise Levels

                               C.1 General

    C.1.1 The root-mean-square (RMS) noise level is the standard measure 
of noise in this addendum. The RMS noise level of a contiguous segment 
of a spectrum is defined as the RMS difference (RMSD) between the 
absorbance values which form the segment and the mean value of that 
segment (see appendix A of this addendum).
    C.1.2 The RMS noise value in double-beam absorbance spectra is 
assumed to be inversely proportional to: (a) the square root of the 
signal integration period of the sample single beam spectra from which 
it is formed, and (b) the total infrared power transmitted through the 
interferometer and absorption cell.
    C.1.3 Practically, the assumption of C.1.2 allows the RMS noise 
level of a complete system to be estimated from the quantities described 
in sections C.1.3.1 through C.1.3.4:
    C.1.3.1 RMSMAN, the noise level of the system (in 
absorbance units), without the absorption cell and transfer optics, 
under those conditions necessary to yield the specified minimum 
instrumental linewidth, e.g., Jacquinot stop size.
    C.1.3.2 tMAN, the manufacturer's signal integration time 
used to determine RMSMAN.
    C.1.3.3 tSS, the signal integration time for the 
analyses.
    C.1.3.4 TP, the manufacturer's estimate of the fraction of the total 
infrared power transmitted by the absorption cell and transfer optics 
from the interferometer to the detector.

                            C.2 Calculations

    C.2.1 Obtain the values of RMSMAN, tMAN, and 
TP from the manufacturers of the equipment, or determine the noise level 
by direct measurements with the completely constructed system proposed 
in section 4 of this addendum.
    C.2.2 Calculate the noise value of the system (RMSEST) 
using equation C.1.

 Appendix D to Addendum to Method 320--Estimating Minimum Concentration 
                 Measurement Uncertainties (MAU and MIU)

                               D.1 General

    Estimate the minimum concentration measurement uncertainties for the 
ith analyte (MAUi) and jth interferant 
(MIUj) based on the spectral data in the mth 
analytical region by comparing the analyte band area in the analytical 
region (AAIim) and estimating or measuring the noise level of 
the system (RMSEST or RMSSM).

    Note: For a single analytical region, the MAU or MIU value is the 
concentration of the analyte or interferant for which the band area is 
equal to the product of the analytical region width (in wavenumbers) and 
the noise level of the system (in absorbance units). If data from more 
than one analytical region are used in the determination of an analyte 
concentration, the MAU or MIU is the mean of the separate MAU or MIU 
values calculated for each analytical region.

                            D.2 Calculations

    D.2.1 For each analytical region, set RMS = RMSSM if 
measured (appendix G of this addendum), or set RMS = RMSEST 
if estimated (appendix C of this addendum).
    D.2.2 For each analyte associated with the analytical region, 
calculate MAUim using equation D.1,
[GRAPHIC] [TIFF OMITTED] TR14JN99.020

    D.2.3 If only the mth analytical region is used to 
calculate the concentration of the ith analyte, set 
MAUi = MAUim.
    D.2.4 If more than one analytical region is used to calculate the 
concentration of the ith analyte, set MAUi equal 
to the weighted mean of the appropriate MAUim values 
calculated above; the weight for each term in the mean is equal to the 
fraction of the total wavenumber range used for the calculation

[[Page 1126]]

represented by each analytical region. Mathematically, if the set of 
analytical regions employed is [m'], then the MAU for each analytical 
region is given by equation D.2.
[GRAPHIC] [TIFF OMITTED] TR14JN99.021

where the weight Wik is defined for each term in the sum as
[GRAPHIC] [TIFF OMITTED] TR14JN99.022

    D.2.5 Repeat sections D.2.1 through D.2.4 of this appendix to 
calculate the analogous values MIUj for the interferants j = 
1 to J. Replace the value (AUi) (DLi) in equation 
D.1 with CPOTj/20; replace the value AAIim in 
equation D.1 with IAIjm.

      Appendix E to Addendum to Method 320--Determining Fractional 
                   Reproducibility Uncertainties (FRU)

                               E.1 General

    To estimate the reproducibility of the spectroscopic results of the 
system, compare the CTS spectra recorded before and after preparing the 
reference spectra. Compare the difference between the spectra to their 
average band area. Perform the calculation for each analytical region on 
the portions of the CTS spectra associated with that analytical region.

                            E.2 Calculations

    E.2.1 The CTS spectra {R1[squ] consist of N spectra, denoted by 
S1i, i=1, N. Similarly, the CTS spectra {R2[squ] consist of N 
spectra, denoted by S2i, i=1, N. Each Ski is the 
spectrum of a single compound, where i denotes the compound and k 
denotes the set {[squ] of which Ski is a member. Form the 
spectra S3 according to S3i = S2i-
S1i for each i. Form the spectra S4 according to 
S4i = [S2i+S1i]/2 for each i.
    E.2.2 Each analytical region m is associated with a portion of the 
CTS spectra S2i and S1i, for a particular i, with 
lower and upper wavenumber limits FFLm and FFUm, 
respectively.
    E.2.3 For each m and the associated i, calculate the band area of 
S4i in the wavenumber range FFUm to 
FFLm. Follow the guidelines of section B.1.2 of this addendum 
for this band area calculation. Denote the result by BAVm.
    E.2.4 For each m and the associated i, calculate the RMSD of 
S3i between the absorbance values and their mean in the 
wavenumber range FFUm to FFLm. Denote the result 
by SRMSm.
    E.2.5 For each analytical region m, calculate FMm using 
equation E.1,
[GRAPHIC] [TIFF OMITTED] TR14JN99.023

    E.2.6 If only the mth analytical region is used to 
calculate the concentration of the ith analyte, set 
FRUi = FMm.
    E.2.7 If a number pi of analytical regions are used to 
calculate the concentration of the ith analyte, set 
FRUi equal to the weighted mean of the appropriate 
FMm values calculated according to section E.2.5. 
Mathematically, if the set of analytical regions employed is {m'[squ], 
then FRUi is given by equation E.2,
[GRAPHIC] [TIFF OMITTED] TR14JN99.024

where the Wik are calculated as described in appendix D of 
this addendum.

Appendix F of Addendum to Method 320--Determining Fractional Calibration 
                           Uncertainties (FCU)

                               F.1 General

    F.1.1 The concentrations yielded by the computerized analytical 
program applied to each single-compound reference spectrum are defined 
as the indicated standard concentrations (ISC's). The ISC values for a 
single compound spectrum should ideally equal the accepted standard 
concentration (ASC) for one analyte or interferant, and should ideally 
be zero for all other compounds. Variations from these results are 
caused by errors in the ASC values, variations from the Beer's law (or 
modified Beer's law) model used to determine the concentrations, and

[[Page 1127]]

noise in the spectra. When the first two effects dominate, the 
systematic nature of the errors is often apparent and the analyst shall 
take steps to correct them.
    F.1.2 When the calibration error appears non-systematic, apply the 
procedures of sections F.2.1 through F.2.3 of this appendix to estimate 
the fractional calibration uncertainty (FCU) for each compound. The FCU 
is defined as the mean fractional error between the ASC and the ISC for 
all reference spectra with non-zero ASC for that compound. The FCU for 
each compound shall be less than the required fractional uncertainty 
specified in section 4.1 of this addendum.
    F.1.3 The computerized analytical programs shall also be required to 
yield acceptably low concentrations for compounds with ISC = 0 when 
applied to the reference spectra. The ISC of each reference spectrum for 
each analyte or interferant shall not exceed that compound's minimum 
measurement uncertainty (MAU or MIU).

                            F.2 Calculations

    F.2.1 Apply each analytical program to each reference spectrum. 
Prepare a similar table to that in Figure F.1 to present the ISC and ASC 
values for each analyte and interferant in each reference spectrum. 
Maintain the order of reference file names and compounds employed in 
preparing Figure F.1.
    F.2.2 For all reference spectra in Figure F.1, verify that the 
absolute values of the ISC's are less than the compound's MAU (for 
analytes) or MIU (for interferants).
    F.2.3 For each analyte reference spectrum, calculate the quantity 
(ASC-ISC)/ASC. For each analyte, calculate the mean of these values (the 
FCUi for the ith analyte) over all reference 
spectra. Prepare a similar table to that in Figure F.2 to present the 
FCUi and analytical uncertainty limit (AUi) for 
each analyte.

                         Measuring Noise Levels

                               G.1 General

    The root-mean-square (RMS) noise level is the standard measure of 
noise. The RMS noise level of a contiguous segment of a spectrum is the 
RMSD between the absorbance values that form the segment and the mean 
value of the segment (see appendix A of this addendum).

    G.2.1 Evacuate the absorption cell or fill it with UPC grade 
nitrogen at approximately one atmosphere total pressure.
    G.2.2 Record two single beam spectra of signal integration period 
tSS.
    G.2.3 Form the double beam absorption spectrum from these two single 
beam spectra, and calculate the noise level RMSSm in the M 
analytical regions.

  Appendix H of Addendum to Method 320--Determining Sample Absorption 
 Pathlength (LS) and Fractional Analytical Uncertainty (FAU)

                               H.1 General

    Reference spectra recorded at absorption pathlength (LR), 
gas pressure (PR), and gas absolute temperature 
(TR) may be used to determine analyte concentrations in 
samples whose spectra are recorded at conditions different from that of 
the reference spectra, i.e., at absorption pathlength (LS), 
absolute temperature (TS), and pressure (PS). This 
appendix describes the calculations for estimating the fractional 
uncertainty (FAU) of this practice. It also describes the calculations 
for determining the sample absorption pathlength from comparison of CTS 
spectra, and for preparing spectra for further instrumental and 
procedural checks.
    H.1.1 Before sampling, determine the sample absorption pathlength 
using least squares analysis. Determine the ratio LS/
LR by comparing the spectral sets {R1[squ] and {R3[squ], 
which are recorded using the same CTS at LS and 
LR, and TS and TR, but both at 
PR.
    H.1.2 Determine the fractional analysis uncertainty (FAU) for each 
analyte by comparing a scaled CTS spectral set, recorded at 
LS, TS, and PS, to the CTS reference 
spectra of the same gas, recorded at LR, TR, and 
PR. Perform the quantitative comparison after recording the 
sample spectra, based on band areas of the spectra in the CTS absorbance 
band associated with each analyte.

    H.2.1 Absorption Pathlength Determination. Perform and document 
separate linear baseline corrections to each analytical region in the 
spectral sets {R1[squ] and {R3[squ]. Form a one-dimensional array 
AR containing the absorbance values from all segments of 
{R1[squ] that are associated with the analytical regions; the members of 
the array are ARi, i = 1, n. Form a similar one-dimensional 
array AS from the absorbance values in the spectral set 
{R3[squ]; the members of the array are ASi, i = 1, n. Based 
on the model AS = rAR + E, determine the least-
squares estimate of r, the value of r which minimizes the square error 
E2. Calculate the sample absorption pathlength, 
LS, using equation H.1,

    H.2.2 Fractional Analysis Uncertainty. Perform and document separate 
linear baseline corrections to each analytical region in the spectral 
sets {R1[squ] and {R4[squ]. Form the arrays AS and 
AR as described in section H.2.1 of this appendix, using 
values from {R1[squ] to form AR, and values from {R4[squ] to 
form AS. Calculate NRMSE and IAAV using

   Appendix I to Addendum to Method 320--Determining Fractional Model 
                           Uncertainties (FMU)

                               I.1 General

    To prepare analytical programs for FTIR analyses, the sample 
constituents must first be assumed. The calculations in this appendix, 
based upon a simulation of the sample spectrum, shall be used to verify 
the appropriateness of these assumptions. The simulated spectra consist 
of the sum of single compound reference spectra scaled to represent 
their contributions to the sample absorbance spectrum; scaling factors 
are based on the indicated standard concentrations (ISC) and measured 
(sample) analyte and interferant concentrations, the sample and 
reference absorption pathlengths, and the sample and reference gas 
pressures. No band-shape correction for differences in the temperature 
of the sample and reference spectra gases is made; such errors are 
included in the FMU estimate. The actual and simulated sample spectra 
are quantitatively compared to determine the fractional model 
uncertainty; this comparison uses the reference

[[Page 1129]]

spectra band areas and residuals in the difference spectrum formed from 
the actual and simulated sample spectra.

                            I.2 Calculations

    I.2.1 For each analyte (with scaled concentration RSAi), 
select a reference spectrum SAi with indicated standard 
concentration ISCi. Calculate the scaling factors, 
RAi, using equation I.1,
[GRAPHIC] [TIFF OMITTED] TR14JN99.029

Form the spectra SACi by scaling each SAi by the 
factor RAi.
    I.2.2 For each interferant, select a reference spectrum 
SIk with indicated standard concentration ISCk. 
Calculate the scaling factors, RIk, using equation I.2,
[GRAPHIC] [TIFF OMITTED] TR14JN99.030

Form the spectra SICk by scaling each SIk by the 
factor RIk.
    I.2.3 For each analytical region, determine by visual inspection 
which of the spectra SACi and SICk exhibit 
absorbance bands within the analytical region. Subtract each spectrum 
SACi and SICk exhibiting absorbance from the 
sample spectrum SS to form the spectrum SUBS. To 
save analysis time and to avoid the introduction of unwanted noise into 
the subtracted spectrum, it is recommended that the calculation be made 
(1) only for those spectral data points within the analytical regions, 
and (2) for each analytical region separately using the original 
spectrum SS.
    I.2.4 For each analytical region m, calculate the RMSD of 
SUBS between the absorbance values and their mean in the 
region FFUm to FFLm. Denote the result by 
RMSSm.
    I.2.5 For each analyte i, calculate FMm, using equation 
I.3,
[GRAPHIC] [TIFF OMITTED] TR14JN99.031

for each analytical region associated with the analyte.
    I.2.6 If only the mth analytical region is used to 
calculate the concentration of the ith analyte, set 
FMUi=FMm.
    I.2.7 If a number of analytical regions are used to calculate the 
concentration of the ith analyte, set FMi equal to 
the weighted mean of the appropriate FMm values calculated 
using equation I-3. Mathematically, if the set of analytical regions 
employed is {m'[squ], then the fractional model uncertainty, FMU, is 
given by equation I.4,

where Wik is calculated as described in appendix D of this 
addendum.

Appendix J of Addendum to Method 320--Determining Overall Concentration 
                           Uncertainties (OCU)

    The calculations in this addendum estimate the measurement 
uncertainties for various FTIR measurements. The lowest possible overall 
concentration uncertainty (OCU) for an analyte is its MAU value, which 
is an estimate of the absolute concentration uncertainty when spectral 
noise dominates the measurement error. However, if the product of the 
largest fractional concentration uncertainty (FRU, FCU, FAU, or FMU) and 
the measured concentration of an analyte exceeds the MAU for the 
analyte, then the OCU is this product. In mathematical terms, set 
OFUi = MAX{FRUi, FCUi, FAUi, 
FMUi{time}  and OCUi = 
MAX{RSAi*OFUi, MAUi{time} .

 Test Method 321--Measurement of Gaseous Hydrogen Chloride Emissions At 
 Portland Cement Kilns by Fourier Transform Infrared (FTIR) Spectroscopy

                            1.0 Introduction

    This method should be performed by those persons familiar with the 
operation of Fourier Transform Infrared (FTIR) instrumentation in the 
application to source sampling. This document describes the sampling 
procedures for use in the application of FTIR spectrometry for the 
determination of vapor phase hydrogen chloride (HCl) concentrations both 
before and after particulate matter control devices installed at 
portland cement kilns. A procedure for analyte spiking is included for 
quality assurance. This method is considered to be self validating 
provided that the requirements listed in section 9 of this method are 
followed. The analytical procedures for interpreting infrared spectra 
from emission measurements are described in the ``Protocol For The Use 
of Extractive

[[Page 1130]]

Fourier Transform Infrared (FTIR) Spectrometry in Analyses of Gaseous 
Emissions From Stationary Industrial Sources'', included as an addendum 
to proposed Method 320 of this appendix (hereafter referred to as the 
``FTIR Protocol)''. References 1 and 2 describe the use of FTIR 
spectrometry in field measurements. Sample transport presents the 
principal difficulty in directly measuring HCl emissions. This identical 
problem must be overcome by any extractive measurement method. HCl is 
reactive and water soluble. The sampling system must be adequately 
designed to prevent sample condensation in the system.

                        1.1 Scope and Application

    This method is specifically designed for the application of FTIR 
Spectrometry in extractive measurements of gaseous HCl concentrations in 
portland cement kiln emissions.

                            1.2 Applicability

    This method applies to the measurement of HCl [CAS No. 7647-01-0]. 
This method can be applied to the determination of HCl concentrations 
both before and after particulate matter control devices installed at 
portland cement manufacturing facilities. This method applies to either 
continuous flow through measurement (with isolated sample analysis) or 
grab sampling (batch analysis). HCl is measured using the mid-infrared 
spectral region for analysis (about 400 to 4000 cm-1 or 25 to 
2.5 [mu]m). Table 1 lists the suggested analytical region for 
quantification of HCl taking the interference from water vapor into 
consideration.

                    1.3 Method Range and Sensitivity

    1.3.1 The analytical range is determined by the instrumental design 
and the composition of the gas stream. For practical purposes there is 
no upper limit to the range because the pathlength may be reduced or the 
sample may be diluted. The lower detection range depends on (1) the 
absorption coefficient of the compound in the analytical frequency 
region, (2) the spectral resolution, (3) the interferometer sampling 
time, (4) the detector sensitivity and response, and (5) the absorption 
pathlength.
    1.3.2 The practical lower quantification range is usually higher 
than the instrument sensitivity allows and is dependent upon (1) the 
presence of interfering species in the exhaust gas including 
H2O, CO2, and SO2, (2) analyte losses 
in the sampling system, (3) the optical alignment of the gas cell and 
transfer optics, and (4) the quality of the reflective surfaces in the 
cell (cell throughput). Under typical test conditions (moisture content 
of up to 30% and CO2 concentrations from 1 to 15 percent), a 
22 meter path length cell with a suitable sampling system may achieve a 
lower quantification range of from 1 to 5 ppm for HCl.

                       1.4 Data Quality Objectives

    1.4.1 In designing or configuring the analytical system, data 
quality is determined by measuring of the root mean square deviation 
(RMSD) of the absorbance values within a chosen spectral (analytical) 
region. The RMSD provides an indication of the signal-to-noise ratio (S/
N) of the spectral baseline. Appendix D of the FTIR Protocol (the 
addendum to Method 320 of this appendix) presents a discussion of the 
relationship between the RMSD, lower detection limit, DLi, 
and analytical uncertainty, AUi. It is important to consider 
the target analyte quantification limit when performing testing with 
FTIR instrumentation, and to optimize the system to achieve the desired 
detection limit.
    1.4.2 Data quality is determined by measuring the root mean square 
(RMS) noise level in each analytical spectral region (appendix C of the 
FTIR Protocol). The RMS noise is defined as the root mean square 
deviation (RMSD) of the absorbance values in an analytical region from 
the mean absorbance value in the same region. Appendix D of the FTIR 
Protocol defines the minimum analyte uncertainty (MAU), and how the RMSD 
is used to calculate the MAU. The MAUim is the minimum 
concentration of the ith analyte in the mth analytical region for which 
the analytical uncertainty limit can be maintained. Table 2 presents 
example values of AU and MAU using the analytical region presented in 
Table 1.

                          2.0 Summary of Method

                              2.1 Principle

    See Method 320 of this appendix. HCl can also undergo rotation 
transitions by absorbing energy in the far-infrared spectral region. The 
rotational transitions are superimposed on the vibrational fundamental 
to give a series of lines centered at the fundamental vibrational 
frequency, 2885 cm-\1\. The frequencies of absorbance and the pattern of 
rotational/vibrational lines are unique to HCl. When this distinct 
pattern is observed in an infrared spectrum of an unknown sample, it 
unequivocally identifies HCl as a component of the mixture. The infrared 
spectrum of HCl is very distinctive and cannot be confused with the 
spectrum of any other compound. See Reference 6.
    2.2 Sampling and Analysis. See Method 320 of this appendix.
    2.3 Operator Requirements. The analyst must have knowledge of 
spectral patterns to choose an appropriate absorption path length or 
determine if sample dilution is necessary. The analyst should also 
understand FTIR instrument operation well enough to choose instrument 
settings that are consistent with the objectives of the analysis.

                             3.0 Definitions

    See appendix A of the FTIR Protocol.

                            4.0 Interferences

    This method will not measure HCl under conditions: (1) where the 
sample gas stream can condense in the sampling system or the 
instrumentation, or (2) where a high moisture content sample relative to 
the analyte concentrations imparts spectral interference due to the 
water vapor absorbance bands. For measuring HCl the first (sampling) 
consideration is more critical. Spectral interference from water vapor 
is not a significant problem except at very high moisture levels and low 
HCl concentrations.
    4.1 Analytical Interferences. See Method 320 of this appendix.
    4.1.1 Background Interferences. See Method 320 of this appendix.
    4.1.2 Spectral interferences. Water vapor can present spectral 
interference for FTIR gas analysis of HCl. Therefore, the water vapor in 
the spectra of kiln gas samples must be accounted for. This means 
preparing at least one spectrum of a water vapor sample where the 
moisture concentration is close to that in the kiln gas.
    4.2 Sampling System Interferences. The principal sampling system 
interferant for measuring HCl is water vapor. Steps must be taken to 
ensure that no condensation forms anywhere in the probe assembly, sample 
lines, or analytical instrumentation. Cold spots anywhere in the 
sampling system must be avoided. The extent of sampling system bias in 
the FTIR analysis of HCl depends on concentrations of potential 
interferants, moisture content of the gas stream, temperature of the gas 
stream, temperature of sampling system components, sample flow rate, and 
reactivity of HCl with other species in the gas stream (e.g., ammonia). 
For measuring HCl in a wet gas stream the temperatures of the gas 
stream, sampling components, and the sample flow rate are of primary 
importance. Analyte spiking with HCl is performed to demonstrate the 
integrity of the sampling system for transporting HCl vapor in the flue 
gas to the FTIR instrument. See section 9 of this method for a complete 
description of analyte spiking.

                               5.0 Safety

    5.1 Hydrogen chloride vapor is corrosive and can cause irritation or 
severe damage to respiratory system, eyes and skin. Exposure to this 
compound should be avoided.
    5.2 This method may involve sampling at locations having high 
positive or negative pressures, or high concentrations of hazardous or 
toxic pollutants, and can not address all safety problems encountered 
under these diverse sampling conditions. It is the responsibility of the 
tester(s) to ensure proper safety and health practices, and to determine 
the applicability of regulatory limitations before performing this test 
method. Leak-check procedures are outlined in section 8.2 of Method 320 
of this appendix.

                       6.0 Equipment and Supplies

    Note: Mention of trade names or specific products does not 
constitute endorsement by the Environmental Protection Agency.

(interferometer, transfer optics, gas cell and detector) having the 
capability of measuring HCl to the predetermined minimum detectable 
level required (see section 4.1.3 of the FTIR Protocol). The system must 
also include an accurate means to control and/or measure the temperature 
of the FTIR gas analysis cell, and a personal computer with compatible 
software that provides real-time updates of the spectral profile during 
sample and spectral collection.

[[Page 1132]]

spike flow rate, having the appropriate calibrated range and a stated 
accuracy of [plusmn]2 percent of the absolute measurement value. This 
device must be calibrated with the major component of the calibration/
spike gas (e.g., nitrogen) using an NIST traceable bubble meter or 
equivalent. Single point calibration checks should be performed daily in 
the field. When spiking HCl, the mass flow meter/controller should be 
thoroughly purged before and after introduction of the gas to prevent 
corrosion of the interior parts.

Torr (133.3 Pa=1 Torr) within [plusmn]5 percent.
    6.8 Sampling Probe. Glass, stainless steel or other appropriate 
material of sufficient length and physical integrity to sustain heating, 
prevent adsorption of analytes and capable of reaching gas sampling 
point.
    6.9 Sampling Line. Heated 180 [deg]C (360 [deg]F) and fabricated of 
either stainless steel, polytetrafluoroethane or other material that 
prevents adsorption of HCl and transports effluent to analytical 
instrumentation. The extractive sample line must have the capability to 
transport sample gas to the analytical components as well as direct 
heated calibration spike gas to the calibration assembly located at the 
sample probe. It is important to minimize the length of heated sample 
line.
    6.10 Particulate Filters. A sintered stainless steel filter rated at 
20 microns or greater may be placed at the inlet of the probe (for 
removal of large particulate matter). A heated filter (Balston or 
equivalent) rated at 1 micron is necessary for primary particulate 
matter removal, and shall be placed immediately after the heated probe. 
The filter/filter holder temperature should be maintained at 180 [deg]C 
(360 [deg]F).

system at the outlet of the probe before the primary particulate filter.
    6.12 Sample Extraction Pump. A leak-free heated head pump (KNF 
Neuberger or equivalent) capable of extracting sample effluent through 
entire sampling system at a rate which prevents analyte losses and 
minimizes analyzer response time. The pump should have a heated by-pass 
and may be placed either before the FTIR instrument or after. If the 
sample pump is located upstream of the FTIR instrument, it must be 
fabricated from materials non-reactive to HCl. The sampling system and 
FTIR measurement system shall allow the operator to obtain at least six 
sample spectra during a one-hour period.

calibrations) to the analytical instrumentation;
    6.14.4 Delivery (optional) of a humidified nitrogen sample stream.
    6.15 Flow Measurement Device. Type S Pitot tube (or equivalent) and 
Magnahelic set for measurement of volumetric flow rate.

                       7.0 Reagents and Standards

    HCl can be purchased in a standard compressed gas cylinder. The most 
stable HCl cylinder mixture available has a concentration certified at 
[plusmn]5 percent. Such a cylinder is suitable for performing analyte 
spiking because it will provide reproducible samples. The stability of 
the cylinder can be monitored over time by periodically performing 
direct FTIR analysis of cylinder samples. It is recommended that a 10-50 
ppm cylinder of HCl be prepared having from 2-5 ppm SF6 as a tracer 
compound. (See sections 7.1 through 7.3 of Method 320 of this appendix 
for a complete description of the use of existing HCl reference spectra. 
See section 9.1 of Method 320 of this appendix for a complete discussion 
of standard concentration selection.)

             8.0 Sample Collection, Preservation and Storage

    See also Method 320 of this appendix.
    8.1 Pretest. A screening test is ideal for obtaining proper data 
that can be used for preparing analytical program files. Information 
from literature surveys and source personnel is also acceptable. 
Information about the sampling location and gas stream composition is 
required to determine the optimum sampling system configuration for 
measuring HCl. Determine the percent moisture of the kiln gas by Method 
4 of appendix A to part 60 of this chapter or by performing a wet bulb/
dry bulb measurement. Perform a preliminary traverse of the sample duct 
or stack and select the sampling point(s). Acquire an initial spectrum 
and determine the optimum operational pathlength of the instrument.

                              8.6 Sampling

    8.6.1 Extractive System. An extractive system maintained at 180 
[deg]C (360 [deg]F) or higher which is capable of directing a total flow 
of at least 12 L/min to the sample cell is required (References 1 and 
2). Insert the probe into the duct or stack at a point representing the 
average volumetric flow rate and 25 percent of the cross sectional area. 
Co-locate an appropriate flow monitoring device with the sample probe so 
that the flow rate is recorded at specified time intervals during 
emission testing (e.g., differential pressure measurements taken every 
10 minutes during each run).
    8.6.2 Batch Samples. Evacuate the absorbance cell to 5 Torr (or 
less) absolute pressure before taking first sample. Fill the cell with 
kiln gas to ambient pressure and record the infrared spectrum, then 
evacuate the cell until there is no further evidence of infrared 
absorption. Repeat this procedure, collecting a total of six separate 
sample spectra within a 1-hour period.
    8.6.3 Continuous Flow Through Sampling. Purge the FTIR cell with 
kiln gas for a time period sufficient to equilibrate the entire sampling 
system and FTIR gas cell. The time required is a function of the 
mechanical response time of the system (determined by performing the 
system calibration with the CTS gas or equivalent), and by the chemical 
reactivity of the target analytes. If the effluent target analyte 
concentration is not variable, observation of the spectral up-date of 
the flowing gas sample should be performed until equilibration of the 
sample is achieved. Isolate the gas cell from the sample flow by 
directing the purge flow to vent. Record the spectrum and pressure of 
the sample gas. After spectral acquisition, allow the sample gas to 
purge the cell with at least three volumes of kiln gas. The time 
required to adequately purge the cell with the required volume of gas is 
a function of (1) cell volume, (2) flow rate through the cell, and (3) 
cell design. It is important that the gas introduction and vent for the 
FTIR cell provides a complete purge through the cell.
    8.6.4 Continuous Sampling. In some cases it is possible to collect 
spectra continuously while the FTIR cell is purged with sample gas. The 
sample integration time, tss, the sample flow rate through 
the gas cell, and the sample integration time must be chosen so that the 
collected data consist of at least 10 spectra with each spectrum being 
of a separate cell volume of flue gas. Sampling in this manner may only 
be performed if the native source analyte concentrations do not affect 
the test results.

                         8.7 Sample Conditioning

    8.7.1 High Moisture Sampling. Kiln gas emitted from wet process 
cement kilns may contain 3- to 40 percent moisture. Zinc selenide 
windows or the equivalent should be used when attempting to analyze hot/
wet kiln gas under these conditions to prevent dissolution of water 
soluble window materials (e.g., KBr).
    8.7.2 Sample Dilution. The sample may be diluted using an in-stack 
dilution probe, or an external dilution device provided that the sample 
is not diluted below the instrument's quantification range. As an 
alternative to using a dilution probe, nitrogen may be dynamically 
spiked into the effluent stream in the same manner as analyte spiking. A 
constant dilution rate shall be maintained throughout the measurement 
process. It is critical to measure and verify the exact dilution ratio 
when using a dilution probe or the nitrogen spiking approach. 
Calibrating the system with a calibration gas containing an appropriate 
tracer compound will allow determination of the dilution ratio for most 
measurement systems. The tester shall specify the procedures used to 
determine the dilution ratio, and include these calibration results in 
the report.
    8.8 Sampling QA, Data Storage and Reporting. See the FTIR Protocol. 
Sample integration times shall be sufficient to achieve the required 
signal-to-noise ratio, and all sample spectra should have unique file 
names. Two copies of sample interferograms and processed spectra will be 
stored on separate computer media. For each sample spectrum the analyst 
must document the sampling conditions, the sampling time (while the cell 
was being filled), the time the spectrum was recorded, the instrumental 
conditions (path length, temperature, pressure, resolution, integration 
time), and the spectral file name. A hard copy of these data must be 
maintained until the test results are accepted.
    8.9 Signal Transmittance. Monitor the signal transmittance through 
the instrumental system. If signal transmittance (relative to the 
background) drops below 95 percent in any spectral region where the 
sample does not absorb infrared energy, then a new background spectrum 
must be obtained.

[[Page 1134]]

    8.10 Post-test CTS. After the sampling run completion, record the 
CTS spectrum. Analysis of the spectral band area used for quantification 
from pre- and post-test CTS spectra should agree to within [plusmn]5 
percent or corrective action must be taken.
    8.11 Post-test QA. The sample spectra shall be inspected immediately 
after the run to verify that the gas matrix composition was close to the 
assumed gas matrix, (this is necessary to account for the concentrations 
of the interferants for use in the analytical analysis programs), and to 
confirm that the sampling and instrumental parameters were appropriate 
for the conditions encountered.

                           9.0 Quality Control

    Use analyte spiking to verify the effectiveness of the sampling 
system for the target compounds in the actual kiln gas matrix. QA 
spiking shall be performed before and after each sample run. QA spiking 
shall be performed after the pre- and post-test CTS direct and system 
calibrations. The system biases calculated from the pre- and post-test 
dynamic analyte spiking shall be within [plusmn]30 percent for the 
spiked surrogate analytes for the measurements to be considered valid. 
See sections 9.3.1 through 9.3.2 for the requisite calculations. 
Measurement of the undiluted spike (direct-to-cell measurement) involves 
sending dry, spike gas to the FTIR cell, filling the cell to 1 
atmosphere and obtaining the spectrum of this sample. The direct-to-cell 
measurement should be performed before each analyte spike so that the 
recovery of the dynamically spiked analytes may be calculated. Analyte 
spiking is only effective for assessing the integrity of the sampling 
system when the concentration of HCl in the source does not vary 
substantially. Any attempt to quantify an analyte recovery in a variable 
concentration matrix will result in errors in the expected concentration 
of the spiked sample. If the kiln gas target analyte concentrations vary 
by more than [plusmn]5 percent (or 5 ppm, whichever is greater) in the 
time required to acquire a sample spectrum, it may be necessary to: (1) 
Use a dual sample probe approach, (2) use two independent FTIR 
measurement systems, (3) use alternate QA/QC procedures, or (4) postpone 
testing until stable emission concentrations are achieved. (See section 
9.2.3 of this method). It is recommended that a laboratory evaluation be 
performed before attempting to employ this method under actual field 
conditions. The laboratory evaluation shall include (1) performance of 
all applicable calculations in section 4 of the FTIR Protocol; (2) 
simulated analyte spiking experiments in dry (ambient) and humidified 
sample matrices using HCl; and (3) performance of bias (recovery) 
calculations from analyte spiking experiments. It is not necessary to 
perform a laboratory evaluation before every field test. The purpose of 
the laboratory study is to demonstrate that the actual instrument and 
sampling system configuration used in field testing meets the 
requirements set forth in this method.
    9.1 Spike Materials. Perform analyte spiking with an HCl standard to 
demonstrate the integrity of the sampling system.
    9.1.1 An HCl standard of approximately 50 ppm in a balance of ultra 
pure nitrogen is recommended. The SF6 (tracer) concentration 
shall be 2 to 5 ppm depending upon the measurement pathlength. The spike 
ratio (spike flow/total flow) shall be no greater than 1:10, and an 
ideal spike concentration should approximate the native effluent 
concentration.
    9.1.2 The ideal spike concentration may not be achieved because the 
target concentration cannot be accurately predicted prior to the field 
test, and limited calibration standards will be available during 
testing. Therefore, practical constraints must be applied that allow the 
tester to spike at an anticipated concentration. For these tests, the 
analyte concentration contributed by the HCl standard spike should be 1 
to 5 ppm or should more closely approximate the native concentration if 
it is greater.

                           9.2 Spike Procedure

    9.2.1 A spiking/sampling apparatus is shown in Figure 2. Introduce 
the spike/tracer gas mixture at a constant flow ([plusmn]2 percent) rate 
at approximately 10 percent of the total sample flow. (For example, 
introduce the surrogate spike at 1 L/min 20 cc/min, into a total sample 
flow rate of 10 L/min). The spike must be pre-heated before introduction 
into the sample matrix to prevent a localized condensation of the gas 
stream at the spike introduction point. A heated sample transport 
line(s) containing multiple transport tubes within the heated bundle may 
be used to spike gas up through the sampling system to the spike 
introduction point. Use a calibrated flow device (e.g., mass flow meter/
controller), to monitor the spike flow as indicated by a calibrated flow 
meter or controller, or alternately, the SF6 tracer ratio may 
be calculated from the direct measurement and the diluted measurement. 
It is often desirable to use the tracer approach in calculating the 
spike/total flow ratio because of the difficulty in accurately measuring 
hot/wet total flow. The tracer technique has been successfully used in 
past validation efforts (Reference 1).
    9.2.2 Perform a direct-to-cell measurement of the dry, undiluted 
spike gas. Introduce the spike directly to the FTIR cell, bypassing the 
sampling system. Fill cell to 1 atmosphere and collect the spectrum of 
this sample. Ensure that the spike gas has equilibrated to the 
temperature of the measurement cell before acquisition of the spectra. 
Inspect the spectrum and verify that the gas

[[Page 1135]]

is dry and contains negligible CO2. Repeat the process to 
obtain a second direct-to-cell measurement. Analysis of spectral band 
areas for HCl from these duplicate measurements should agree to within 
[plusmn]5 percent of the mean.
    9.2.3 Analyte Spiking. Determine whether the kiln gas contains 
native concentrations of HCl by examination of preliminary spectra. 
Determine whether the concentration varies significantly with time by 
observing a continuously up-dated spectrum of sample gas in the flow-
through sampling mode. If the concentration varies by more than 
[plusmn]5 percent during the period of time required to acquire a 
spectra, then an alternate approach should be used. One alternate 
approach uses two sampling lines to convey sample to the gas 
distribution manifold. One of the sample lines is used to continuously 
extract unspiked kiln gas from the source. The other sample line serves 
as the analyte spike line. One FTIR system can be used in this 
arrangement. Spiked or unspiked sample gas may be directed to the FTIR 
system from the gas distribution manifold, with the need to purge only 
the components between the manifold and the FTIR system. This approach 
minimizes the time required to acquire an equilibrated sample of spiked 
or unspiked kiln gas. If the source varies by more than [plusmn]5 
percent (or 5 ppm, whichever is greater) in the time it takes to switch 
from the unspiked sample line to the spiked sample line, then analyte 
spiking may not be a feasible means to determine the effectiveness of 
the sampling system for the HCl in the sample matrix. A second 
alternative is to use two completely independent FTIR measurement 
systems. One system would measure unspiked samples while the other 
system would measure the spiked samples. As a last option, (where no 
other alternatives can be used) a humidified nitrogen stream may be 
generated in the field which approximates the moisture content of the 
kiln gas. Analyte spiking into this humidified stream can be employed to 
assure that the sampling system is adequate for transporting the HCl to 
the FTIR instrumentation.
    9.2.3.1 Adjust the spike flow rate to approximately 10 percent of 
the total flow by metering spike gas through a calibrated mass flowmeter 
or controller. Allow spike flow to equilibrate within the sampling 
system before analyzing the first spiked kiln gas samples. A minimum of 
two consecutive spikes are required. Analysis of the spectral band area 
used for quantification should agree to within [plusmn]5 percent or 
corrective action must be taken.
    9.2.3.2 After QA spiking is completed, the sampling system 
components shall be purged with nitrogen or dry air to eliminate traces 
of the HCl compound from the sampling system components. Acquire a 
sample spectra of the nitrogen purge to verify the absence of the 
calibration mixture.
    9.2.3.3 Analyte spiking procedures must be carefully executed to 
ensure that meaningful measurements are achieved. The requirements of 
sections 9.2.3.3.1 through 9.2.3.3.4 shall be met.
    9.2.3.3.1 The spike must be in the vapor phase, dry, and heated to 
(or above) the kiln gas temperature before it is introduced to the kiln 
gas stream.
    9.2.3.3.2 The spike flow rate must be constant and accurately 
measured.
    9.2.3.3.3 The total flow must also be measured continuously and 
reliably or the dilution ratio must otherwise be verified before and 
after a run by introducing a spike of a non-reactive, stable compound 
(i.e., tracer).
    9.2.3.3.4 The tracer must be inert to the sampling system 
components, not contained in the effluent gas, and readily detected by 
the analytical instrumentation. Sulfur hexafluoride (SF6) has 
been used successfully (References 1 and 2) for this purpose.

                            9.3 Calculations

    9.3.1 Recovery. Calculate the percent recovery of the spiked 
analytes using equations 1 and 2.
[GRAPHIC] [TIFF OMITTED] TR14JN99.033

Sm = Mean concentration of the analyte spiked effluent 
          samples (observed).
          [GRAPHIC] [TIFF OMITTED] TR14JN99.034
          
Ce = Expected concentration of the spiked samples 
          (theoretical).
Df = dilution Factor (Total flow/Spike flow). total flow = 
          spike flow plus effluent flow.
Cs = cylinder concentration of spike gas.
Su = native concentration of analytes in unspiked samples.

The spike dilution factor may be confirmed by measuring the total flow 
and the spike flow directly. Alternately, the spike dilution can be 
verified by comparing the concentration of the tracer compound in the 
spiked samples (diluted) to the tracer concentration in the direct 
(undiluted) measurement of the spike gas.
If SF6 is the tracer gas, then

[SF6]spike = the diluted SF6 
          concentration measured in a spiked sample.
[SF6]direct = the SF6 concentration 
          measured directly.

    9.3.2 Bias. The bias may be determined by the difference between the 
observed spike value and the expected response (i.e., the equivalent 
concentration of the spiked material plus the analyte concentration 
adjusted

[[Page 1136]]

for spike dilution). Bias is defined by section 6.3.1 of EPA Method 301 
of this appendix (Reference 8) as,
[GRAPHIC] [TIFF OMITTED] TR14JN99.036

Where:
B = Bias at spike level.
Sm = Mean concentration of the analyte spiked samples.
Ce = Expected concentration of the analyte in spiked samples.

Acceptable recoveries for analyte spiking are [plusmn]30 percent. 
Application of correction factors to the data based upon bias and 
recovery calculations is subject to the approval of the Administrator.

                  10.0 Calibration and Standardization

    10.1 Calibration transfer standards (CTS). The EPA Traceability 
Protocol gases or NIST traceable standards, with a minimum accuracy of 
[plusmn]2 percent shall be used. For other requirements of the CTS, see 
the FTIR Protocol section 4.5.
    10.2 Signal-to-Noise Ratio (S/N). The S/N shall be less than the 
minimum acceptable measurement uncertainty in the analytical regions to 
be used for measuring HCl.
    10.3 Absorbance Pathlength. Verify the absorbance path length by 
comparing CTS spectra to reference spectra of the calibration gas(es).
    10.4 Instrument Resolution. Measure the line width of appropriate 
CTS band(s) to verify instrumental resolution.
    10.5 Apodization Function. Choose the appropriate apodization 
function. Determine any appropriate mathematical transformations that 
are required to correct instrumental errors by measuring the CTS. Any 
mathematical transformations must be documented and reproducible. 
Reference 9 provides additional information about FTIR instrumentation.

                        11.0 Analytical Procedure

    A full description of the analytical procedures is given in sections 
4.6-4.11, sections 5, 6, and 7, and the appendices of the FTIR Protocol. 
Additional description of quantitative spectral analysis is provided in 
References 10 and 11.

                   12.0 Data Analysis and Calculations

    Data analysis is performed using appropriate reference spectra whose 
concentrations can be verified using CTS spectra. Various analytical 
programs (References 10 and 11) are available to relate sample 
absorbance to a concentration standard. Calculated concentrations should 
be verified by analyzing spectral baselines after mathematically 
subtracting scaled reference spectra from the sample spectra. A full 
description of the data analysis and calculations may be found in the 
FTIR Protocol (sections 4.0, 5.0, 6.0 and appendices).
    12.1 Calculated concentrations in sample spectra are corrected for 
differences in absorption pathlength between the reference and sample 
spectra by
[GRAPHIC] [TIFF OMITTED] TR14JN99.037

Where:

Ccorr = The pathlength corrected concentration.
Ccalc = The initial calculated concentration (output of the 
          multicomponent analysis program designed for the compound).
Lr = The pathlength associated with the reference spectra.
Ls = The pathlength associated with the sample spectra.
Ts = The absolute temperature (K) of the sample gas.
Tr = The absolute temperature (K) at which reference spectra 
          were recorded.

    12.2 The temperature correction in equation 5 is a volumetric 
correction. It does not account for temperature dependence of 
rotational-vibrational relative line intensities. Whenever possible, the 
reference spectra used in the analysis should be collected at a 
temperature near the temperature of the FTIR cell used in the test to 
minimize the calculated error in the measurement (FTIR Protocol, 
appendix D). Additionally, the analytical region chosen for the analysis 
should be sufficiently broad to minimize errors caused by small 
differences in relative line intensities between reference spectra and 
the sample spectra.

                         13.0 Method Performance

    A description of the method performance may be found in the FTIR 
Protocol. This method is self validating provided the results meet the 
performance specification of the QA spike in sections 9.0 through 9.3 of 
this method.

                        14.0 Pollution Prevention

    This is a gas phase measurement. Gas is extracted from the source, 
analyzed by the instrumentation, and discharged through the instrument 
vent.

    Appendix C to Part 63--Determination of the Fraction Biodegraded 
            (Fbio) in a Biological Treatment Unit

                               I. Purpose

    The purpose of this appendix is to define the procedures for an 
owner or operator to use to calculate the site specific fraction of 
organic compounds biodegraded (Fbio) in a biological 
treatment unit. If an acceptable level of organic compounds is destroyed 
rather than emitted to the air or remaining in the effluent, the 
biological treatment unit may be used to comply with the applicable 
treatment requirements without the unit being covered and vented through 
a closed vent system to an air pollution control device.
    The determination of Fbio shall be made on a system as it 
would exist under the rule. The owner or operator should anticipate 
changes that would occur to the wastewater flow and concentration of 
organics, to be treated by the biological treatment unit, as a result of 
enclosing the collection and treatment system as required by the rule.
    Unless otherwise specified, the procedures presented in this 
appendix are designed to be applied to thoroughly mixed treatment units. 
A thoroughly mixed treatment unit is a unit that is designed and 
operated to approach or achieve uniform biomass distribution and organic 
compound concentration throughout the aeration unit by quickly 
dispersing the recycled biomass and the wastewater entering the unit. 
Detailed discussion on how to determine if a biological treatment unit 
is thoroughly mixed can be found in reference 7. Systems that are not 
thoroughly mixed treatment units should be subdivided into a series of 
zones that have uniform characteristics within each zone. The number of 
zones required to characterize a biological treatment system will depend 
on the design and operation of the treatment system. Detailed discussion 
on how to determine the number of zones in a biological treatment unit 
and examples of determination of f bio can be found in 
reference 8. Each zone should then be modeled as a separate unit. The 
amount of air emissions and biodegradation from the modeling of these 
separate zones can then be added to reflect the entire system.

                             II. Definitions

    Biological treatment unit = wastewater treatment unit designed and 
operated to promote the growth of bacteria to destroy organic materials 
in wastewater.

fbio = The fraction of individual applicable organic 
          compounds in the wastewater biodegraded in a biological 
          treatment unit.
Fbio = The fraction of total applicable organic compounds in 
          the wastewater biodegraded in a biological treatment unit.
Fe = The fraction of applicable organic compounds emitted from the 
          wastewater to the atmosphere.
K1 = First order biodegradation rate constant, L/g MLVSS-hr
KL = liquid-phase mass transfer coefficient, m/s
M = compound specific mass flow weighted average of organic compounds in 
          the wastewater, Mg/Yr

          III. Procedures for Determination of fbio

    The first step in the analysis to determine if a biological 
treatment unit may be used without being covered and vented through a 
closed-vent system to an air pollution control device is to determine 
the compound-specific fbio. The following procedures may be 
used to determine fbio:
    (1) The EPA Test Method 304A or 304B (appendix A, part 63)--Method 
for the Determination of Biodegradation Rates of Organic Compounds,
    (2) Performance data with and without biodegradation,
    (3) Inlet and outlet concentration measurements,
    (4) Batch tests,
    (5) Multiple zone concentration measurements.
    All procedures must be executed so that the resulting 
fbio is based on the collection system and waste management 
units being in compliance with the rule. If the collection system and 
waste management units meet

[[Page 1141]]

the suppression requirements at the time of the test, any of the 
procedures may be chosen. If the collection system and waste management 
units are not in compliance at the time of the performance test, then 
only Method 304A, B, or the batch test shall be chosen. If Method 304A, 
B, or the batch test is used, any anticipated changes to the influent of 
the full-scale biological treatment unit that will occur after the 
facility has enclosed the collection system must be represented in the 
influent feed to the benchtop bioreactor unit, or test unit.
    Select one or more appropriate procedures from the five listed above 
based on the availability of site specific data and the type of mixing 
that occurs in the unit (thoroughly mixed or multiple mixing zone). If 
the facility does not have site-specific data on the removal efficiency 
of its biological treatment unit, then Procedure 1 or Procedure 4 may be 
used. Procedure 1 allows the use of a benchtop bioreactor to determine 
the first-order biodegradation rate constant. An owner or operator may 
elect to assume the first order biodegradation rate constant is zero for 
any regulated compound(s) present in the wastewater. Procedure 4 
explains two types of batch tests which may be used to estimate the 
first order biodegradation rate constant. An owner or operator may elect 
to assume the first order biodegradation rate constant is zero for any 
regulated compound(s) present in the wastewater. Procedure 3 would be 
used if the facility has, or measures to determine, data on the inlet 
and outlet individual organic compound concentration for the biological 
treatment unit. Procedure 3 may only be used on a thoroughly mixed 
treatment unit. Procedure 5 is the concentration measurement test that 
can be used for units with multiple mixing zones. Procedure 2 is used if 
a facility has or obtains performance data on a biotreatment unit prior 
to and after addition of the microbial mass. An example where Procedure 
2 could be used is an activated sludge unit where measurements have been 
taken on inlet and exit concentration of organic compounds in the 
wastewater prior to seeding with the microbial mass and startup of the 
unit. The flow chart in figure 1 outlines the steps to use for each of 
the procedures.

                  A. Method 304A or 304B (Procedure 1)

    If the first procedure is selected, follow the instructions in 
appendix A of part 63 Method 304A ``Method for the Determination of 
Biodegradation Rates of Organic Compounds (Vented Option)'' or Method 
304B ``Method for the Determination of Biodegradation Rates of Organic 
Compounds (Scrubber Option).'' Method 304A or 304B provides instruction 
on setting up and operating a self-contained benchtop bioreactor system 
which is operated under conditions representative of the target full-
scale system. Method 304A uses a benchtop bioreactor system with a vent, 
and uses modeling to estimate any air emissions. Method 304B uses a 
benchtop bioreactor system which is equipped with a scrubber and is not 
vented.
    There are some restrictions on which method a source may use. If the 
facility is measuring the rate of biodegradation of compounds that may 
tend to react or hydrolyze in the scrubber of Method 304B, this method 
shall not be used and Method 304A is the required method. If a Henry's 
law value is not available to use with Form V, then Method 304A shall 
not be used and Method 304B is the required method. When using either 
method, the feed flow to the benchtop bioreactor shall be representative 
of the flow and concentration of the wastewater that will be treated by 
the full-scale biological treatment unit after the collection and 
treatment system has been enclosed as required under the applicable 
subpart.
    The conditions under which the full-scale biological treatment unit 
is run establish the operating parameters of Method 304A or 304B. If the 
biological treatment unit is operated under abnormal operating 
conditions (conditions outside the range of critical parameters examined 
and confirmed in the laboratory), the EPA believes this will adversely 
affect the biodegradation rate and is an unacceptable treatment option. 
The facility would be making multiple runs of the test method to 
simulate the operating range for its biological treatment unit. For wide 
ranges of variation in operating parameters, the facility shall 
demonstrate the biological treatment unit is achieving an acceptable 
level of control, as required by the regulation, across the ranges and 
not only at the endpoints.
    If Method 304A is used, complete Form V initially. Form V is used to 
calculate K1 from the Method 304A results. Form V uses the Henry's law 
constant to estimate the fraction lost from the benchtop reactor vent. 
The owner or operator shall use the Henry's law values in Table I. Form 
V also gives direction for calculating an equivalent KL. Note on Form V 
if the calculated number for line 11 is greater than the calculated 
value for line 13, this procedure shall not be used to demonstrate the 
compound is biodegradable. If line 11 is greater than line 13, this is 
an indication the fraction emitted from the vent is greater than the 
fraction biodegraded. The equivalent KL determined on Form V is used in 
Form II (line 6). Estimation of the Fe and fbio must be done 
following the steps in Form III. Form III uses the previously calculated 
values of K1 and KL (equivalent KL), and site-specific parameters of the 
full-scale bioreactor as input to the calculations. Forms II, III, and V 
must be completed for each organic compound in the wastewater to 
determine Fe and fbio.

[[Page 1142]]

    If Method 304B is used, perform the method and use the measurements 
to determine K1, which is the first-order biodegradation rate constant. 
Form I lists the sequence of steps in the procedure for calculating K1 
from the Method 304B results. Once K1 is determined, KL must be 
calculated by use of mass transfer equations. Form II outlines the 
procedure to follow for use of mass transfer equations to determine KL. 
A computer program which incorporates these mass transfer equations may 
be used. Water7 is a program that incorporates these mass transfer 
equations and may be used to determine KL. Refer to Form II-A to 
determine KL, if Water7 or the most recent update to this model is used. 
In addition, the Bay Area Sewage Toxics Emission (BASTE) model version 
3.0 or equivalent upgrade and the TOXCHEM (Environment Canada's 
Wastewater Technology Centre and Environmega, Ltd.) model version 1.10 
or equivalent upgrade may also be used to determine KL for the 
biological treatment unit with several stipulations. The programs must 
be altered to output a KL value which is based on the site-specific 
parameters of the unit modeled, and the Henry's law values listed in 
Table I must be substituted for the existing Henry's law values in the 
programs. Input values used in the model and corresponding output values 
shall become documentation of the fbio determination. The 
owner or operator should be aware these programs do not allow modeling 
of certain units. To model these units, the owner or operator shall use 
one of the other appropriate procedures as outlined in this appendix. 
The owner or operator shall not use a default value for KL. The KL value 
determined by use of these models shall be based on the site-specific 
parameters of the specific unit. This KL value shall be inserted in Form 
II (line 6). Estimation of the Fe and fbio must be done 
following the steps in Form III. Form III uses the previously calculated 
values of K1 and KL, and site-specific parameters of the full-scale 
bioreactor as input to the calculations. Forms I, II, and III must be 
completed for each organic compound in the wastewater to determine Fe 
and fbio.

    B. Performance Data With and Without Biodegradation (Procedure 2)

    Procedure 2 uses site-specific performance data that represents or 
characterizes operation of the unit both with and without 
biodegradation. As previously mentioned, proper determination of 
fbio must be made on a system as it would exist under the 
rule. Using Form IV, calculate KL and K1. After KL and K1 are 
determined, Form III is used to calculate Fe and fbio for 
each organic compound present in the wastewater.

      C. Inlet and Outlet Concentration Measurements (Procedure 3)

    Procedure 3 uses measured inlet and outlet organic compound 
concentrations for the unit. This procedure may only be used on a 
thoroughly mixed treatment unit. Again, proper determination of 
fbio must be made on a system as it would exist under the 
rule. The first step in using this procedure is to calculate KL using 
Form II. A computer model may be used. If the Water7 model or the most 
recent update to this model is used, then use Form II-A to calculate KL. 
After KL is determined using field data, complete Form VI to calculate 
K1. The TOXCHEM or BASTE model may also be used to calculate KL for the 
biological treatment unit, with the stipulations listed in procedure 
304B. After KL and K1 are determined, Form III is used to calculate Fe 
and fbio for each organic compound.

                      D. Batch Tests (Procedure 4)

    Two types of batch tests which may be used to determine kinetic 
parameters are: (1) The aerated reactor test and (2) the sealed reactor 
test. The aerated reactor test is also known as the BOX test (batch test 
with oxygen addition). The sealed reactor test is also known as the 
serum bottle test. These batch tests should be conducted only by persons 
familiar with procedures for determining biodegradation kinetics. 
Detailed discussions of batch procedures for determining biodegradation 
kinetic parameters can be found in references 1-4.
    For both batch test approaches, a biomass sample from the activated 
sludge unit of interest is collected, aerated, and stored for no more 
than 4 hours prior to testing. To collect sufficient data when 
biodegradation is rapid, it may be necessary to dilute the biomass 
sample. If the sample is to be diluted, the biomass sample shall be 
diluted using treated effluent from the activated sludge unit of 
interest to a concentration such that the biodegradation test will last 
long enough to make at least six concentration measurements. It is 
recommended that the tests not be terminated until the compound 
concentration falls below the limit of quantitation (LOQ). Measurements 
that are below the LOQ should not be used in the data analysis. Biomass 
concentrations shall be determined using standard methods for 
measurement of mixed liquor volatile suspended solids (MLVSS) (reference 
5).
    The change in concentration of a test compound may be monitored by 
either measuring the concentration in the liquid or in the reactor 
headspace. The analytical technique chosen for the test should be as 
sensitive as possible. For the batch test procedures described in this 
section, equilibrium conditions must exist between the liquid and gas 
phases of the experiments because the

[[Page 1143]]

data analysis procedures are based on this premise. To use the headspace 
sampling approach, the reactor headspace must be in equilibrium with the 
liquid so that the headspace concentrations can be correlated with the 
liquid concentrations. Before the biodegradation testing is conducted, 
the equilibrium assumption must be verified. A discussion of the 
equilibrium assumption verification is given below in sections D.1 and 
D.2 since different approaches are required for the two types of batch 
tests.
    To determine biodegradation kinetic parameters in a batch test, it 
is important to choose an appropriate initial substrate (compound(s) of 
interest) concentration for the test. The outcome of the batch 
experiment may be influenced by the initial substrate (SO) to 
biomass (XO) ratio (see references 3, 4, and 6). This ratio 
is typically measured in chemical oxygen demand (COD) units. When the 
SO/XO ratio is low, cell multiplication and growth 
in the batch test is negligible and the kinetics measured by the test 
are representative of the kinetics in the activated sludge unit of 
interest. The SO/XO ratio for a batch test is 
determined with the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JA97.034

Where:

SO/XO=initial substrate to biomass ratio on a COD 
          basis
Si=initial substrate concentration in COD units (g COD/L)
X=biomass concentration in the batch test (g MLVSS/L)
1.42 = Conversion factor to convert to COD units

    For the batch tests described in this section, the SO/
XO ratio (on a COD basis) must be initially less than 0.5.
    1. Aerated Reactor Test. An aerated draft tube reactor may be used 
for the biokinetics testing (as an example see Figure 2 of appendix C). 
Other aerated reactor configurations may also be used. Air is bubbled 
through a porous frit at a rate sufficient to aerate and keep the 
reactor uniformly mixed. Aeration rates typically vary from 50 to 200 
ml/min for a 1 liter system. A mass flow rate controller is used to 
carefully control the air flow rate because it is important to have an 
accurate measure of this rate. The dissolved oxygen (DO) concentration 
in the system must not fall below 2 mg/liter so that the biodegradation 
observed will not be DO-limited. Once the air flow rate is established, 
the test mixture (or compound) of interest is then injected into the 
reactor and the concentration of the compound(s) is monitored over time. 
Concentrations may be monitored in the liquid or in the headspace. A 
minimum of six samples shall be taken over the period of the test. 
However, it is necessary to collect samples until the compound 
concentration falls below the LOQ. If liquid samples are collected, they 
must be small enough such that the liquid volume in the batch reactor 
does not change by more than 10%.
    Before conducting experiments with biomass, it is necessary to 
verify the equilibrium assumption. The equilibrium assumption can be 
verified by conducting a stripping experiment using the effluent (no 
biomass) from the activated sludge unit of interest. Effluent is 
filtered with a 0.45 um or smaller filter and placed in the draft tube 
reactor. Air is sparged into the system and the compound concentration 
in the liquid or headspace is monitored over time. This test with no 
biomass may provide an estimate of the Henry's law constant. If the 
system is at equilibrium, the Henry's law constant may be estimated with 
the following equation:
[GRAPHIC] [TIFF OMITTED] TR17JA97.035

Where:

C=cencentration at time, t (min)
CO=concentration at t=0
G=volumetric gas flow rate (ml/min)
V=liquid volume in the batch reactor (ml)
Keq=Henry's law constant (mg/L-gas)/(mg/L-liquid)
t=time (min)

    A plot of--ln(C/Co) as a function of t will have a slope 
equal to GKeq/V. The equilibrium assumption can be verified 
by comparing the experimentally determined Keq for the system 
to literature values of the Henry's Law constant (including those listed 
in this appendix). If Keq does not match the Henry's law 
constant, Keq shall be determined from analysis of the 
headspace and liquid concentration in a batch system.
    The concentration of a compound decreases in the bioreactor due to 
both biodegradation and stripping. Biodegradation processes are 
typically described with a Monod model. This model and a stripping 
expression are combined to give a mass balance for the aerated draft 
tube reactor ):

[[Page 1144]]

[GRAPHIC] [TIFF OMITTED] TR17JA97.036

Where:

s=test compound concentration, mg/liter
G=volumetric gas flow rate, liters/hr
Keq=Henry's Law constant measured in the system, (mg/liter 
          gas)/(mg/liter liquid)
V=volume of liquid in the reactor, liters
X=biomass concentration (g MLVSS/liter)
Qm=maximum rate of substrate removal, mg/g MLVSS/hr
KS=Monod biorate constant at half the maximum rate, mg/liter

    Equation App. C-3 can be integrated to obtain the following 
equation:
[GRAPHIC] [TIFF OMITTED] TR22JA01.162

Where:
A=GKeqKs + QmVX
B=GKeq
So=test compound concentration at t=0
    This equation is used along with the substrate concentration versus 
time data to determine the best fit parameters (Qm and 
KS) to describe the biodegradation process in the aerated 
reactor. If the aerated reactor test is used, the following procedure is 
used to analyze the data. Evaluate Keq for the compound of 
interest with Form XI. The concentration in the vented headspace or 
liquid is measured as a function of time and the data is entered on Form 
XI. A plot is made from the data and attached to the Form XI. 
Keq is calculated on Form XI and the results are contrasted 
with the expected value of Henry's law obtained from Form IX. If the 
comparison is satisfactory, the stripping constant is calculated from 
Keq, completing Form XI. The values of Keq may 
differ because the theoretical value of Keq may not be 
applicable to the system of interest. If the comparison of the 
calculated Keq from the form and the expected value of 
Henry's law is unsatisfactory, Form X can alternatively be used to 
validate Keq. If the aerated reactor is demonstrated to not 
be at equilibrium, either modify the reactor design and/or operation, or 
use another type of batch test.
    The compound-specific biorate constants are then measured using Form 
XII. The stripping constant that was determined from Form XI and a 
headspace correction factor of 1 are entered on Form XII. The aerated 
reactor biotest may then be run, measuring concentrations of each 
compound of interest as a function of time. If headspace concentrations 
are measured instead of liquid concentrations, then the corresponding 
liquid concentrations are calculated from the headspace measurements 
using the Keq determined on Form XI and entered on Form XII.
    The concentration data on Form XII may contain scatter that can 
adversely influence the data interpretation. It is possible to curve fit 
the concentration data and enter the concentrations on the fitted curve 
instead of the actual data. If curve fitting is used, the curve-fitting 
procedure must be based upon the Equation App. C-4. When curve fitting 
is used, it is necessary to attach a plot of the actual data and the 
fitted curve to Form XII.
    If the stripping rate constant is relatively large when compared to 
the biorate at low concentrations, it may be difficult to obtain 
accurate evaluations of the first-order biorate constant. In these 
cases, either reducing the stripping rate constant by lowering the 
aeration rate, or increasing the biomass concentrations should be 
considered.
    The final result of the batch testing is the measurement of a 
biorate that can be used to estimate the fraction biodegraded, 
fbio. The number transferred to Form III is obtained from 
Form XII, line 9.
    2. Sealed Reactor Test. This test uses a closed system to prevent 
losses of the test compound by volatilization. This test may be 
conducted using a serum bottle or a sealed draft tube reactor (for an 
example see Figure 3 of appendix C). Since no air is supplied, it is 
necessary to ensure that sufficient oxygen is present in the system. The 
DO concentration in the system must not fall below 2 mg/liter so that 
the biodegradation observed will not be DO-limited. As an alternative, 
oxygen may be supplied by electrolysis as needed to maintain the DO 
concentration above 2 mg/liter. The reactor contents must be uniformly 
mixed, by stirring

[[Page 1145]]

or agitation using a shaker or similar apparatus. The test mixture (or 
compound) of interest is injected into the reactor and the concentration 
is monitored over time. A minimum of six samples shall be taken over the 
period of the test. However, it is necessary to monitor the 
concentration until it falls below the LOQ.
    The equilibrium assumption must be verified for the batch reactor 
system. In this case, Keq may be determined by simultaneously 
measuring gas and liquid phase concentrations at different times within 
a given experiment. A constant ratio of gas/liquid concentrations 
indicates that equilibrium conditions are present and Keq is 
not a function of concentration. This ratio is then taken as the 
Keq for the specific compound in the test. It is not 
necessary to measure Keq for each experiment. If the ratio is 
not constant, the equilibrium assumption is not valid and it is 
necessary to (1) increase mixing energy for the system and retest for 
the equilibrium assumption, or (2) use a different type of test (for 
example, a collapsible volume reactor).
    The concentration of a compound decreases in the bioreactor due to 
biodegradation according to Equation App. C-5:
[GRAPHIC] [TIFF OMITTED] TR17JA97.038

Where:

s=test compound concentration (mg/liters)
Vl=the average liquid volume in the reactor (liters)
Vg=the average gas volume in the reactor (liters)
Qm=maximum rate of substrate removal (mg/g ML VSS/hr)
Keq=Henry's Law constant determined for the test, (mg/liter 
          gas)/(mg/liter liquid)
Ks=Monod biorate constant at one-half the maximum rate (mg/
          liter)
t=time (hours)
X=biomass concentration (g ML VSS/liter )
so=test compound concentration at time t=0

    Equation App. C-5 can be solved analytically to give:
    [GRAPHIC] [TIFF OMITTED] TR22JA01.163
    
    This equation is used along with the substrate concentration versus 
time data to determine the best fit parameters (Qm and 
Ks) to describe the biodegradation process in the sealed 
reactor.
    If the sealed reactor test is used, Form X is used to determine the 
headspace correction factor. The disappearance of a compound in the 
sealed reactor test is slowed because a fraction of the compound is not 
available for biodegradation because it is present in the headspace. If 
the compound is almost entirely in the liquid phase, the headspace 
correction factor is approximately one. If the headspace correction 
factor is substantially less than one, improved mass transfer or reduced 
headspace may improve the accuracy of the sealed reactor test. A 
preliminary sealed reactor test must be conducted to test the 
equilibrium assumption. As the compound of interest is degraded, 
simultaneous headspace and liquid samples should be collected and Form X 
should be used to evaluate Keq. The ratio of headspace to 
liquid concentrations must be constant in order to confirm that 
equilibrium conditions exist. If equilibrium conditions are not present, 
additional mixing or an alternate reactor configuration may be required.
    The compound-specific biorate constants are then calculated using 
Form XII. For the sealed reactor test, a stripping rate constant of zero 
and the headspace correction factor that was determined from Form X are 
entered on Form XII. The sealed reactor test may then be run, measuring 
the concentrations of each compound of interest as a function of time. 
If headspace concentrations are measured instead of liquid 
concentrations, then the corresponding liquid concentrations are 
calculated from the headspace measurements using Keq from 
Form X and entered on Form XII.
    The concentration data on Form XII may contain scatter that can 
adversely influence the data interpretation. It is possible to

[[Page 1146]]

curve fit the concentration data and enter the concentrations on the 
fitted curve instead of the actual data. If curve fitting is used, the 
curve-fitting procedure must be based upon Equation App. C-6. When curve 
fitting is used, it is necessary to attach a plot of the actual data and 
the fitted curve to Form XII.
    If a sealed collapsible reactor is used that has no headspace, the 
headspace correction factor will equal 1, but the stripping rate 
constant may not equal 0 due to diffusion losses through the reactor 
wall. The ratio of the rate of loss of compound to the concentration of 
the compound in the reactor (units of per hour) must be evaluated. This 
loss ratio has the same units as the stripping rate constant and may be 
entered as the stripping rate constant on line 1 of Form XII.
    If the loss due to diffusion through the walls of the collapsible 
reactor is relatively large when compared to the biorate at low 
concentrations, it may be difficult to obtain accurate evaluations of 
the first-order biorate constant. In these cases, either replacing the 
materials used to construct the reactor with materials of low 
permeability or increasing the biomass concentration should be 
considered.
    The final result of the batch testing is the measurement of a 
biorate that can be used to estimate the fraction biodegraded, 
fbio. The number transferred to Form III is obtained from 
Form XII, line 9.
    The number on Form XII line 9 will equal the Monod first-order 
biorate constant if the full-scale system is operated in the first-order 
range. If the full-scale system is operated at concentrations above that 
of the Monod first-order range, the value of the number on line 9 will 
be somewhat lower than the Monod first-order biorate constant. With 
supporting biorate data, the Monod model used in Form XII may be used to 
estimate the effective biorate constant K1 for use in Form III.
    If a reactor with headspace is used, analysis of the data using 
equation App. C-6 is valid only if Vl and Vg do 
not change more than 10% (i.e., they can be approximated as constant for 
the duration of the test). Since biodegradation is occurring only in the 
liquid, as the liquid concentration decreases it is necessary for mass 
to transfer from the gas to the liquid phase. This may require vigorous 
mixing and/or reducing the volume in the headspace of the reactor.
    If there is no headspace (e.g., a collapsible reactor), equation 
App. C-6 is independent of V1 and there are no restrictions 
on the liquid volume. If a membrane or bag is used as the collapsible-
volume reactor, it may be important to monitor for diffusion losses in 
the system. To determine if there are losses, the bag should be used 
without biomass and spiked with the compound(s) of interest. The 
concentration of the compound(s) in the reactor should be monitored over 
time. The data are analyzed as described above for the sealed reactor 
test.
    3. Quality Control/Quality Assurance (QA/QC). A QA/QC plan outlining 
the procedures used to determine the biodegradation rate constants shall 
be prepared and a copy maintained at the source. The plan should 
include, but may not be limited to:
    1. A description of the apparatus used (e.g., size, volume, method 
of supplying air or oxygen, mixing, and sampling procedures) including a 
simplified schematic drawing.
    2. A description of how biomass was sampled from the activated 
sludge unit.
    3. A description of how biomass was held prior to testing (age, 
etc.).
    4. A description of what conditions (DO, gas-liquid equilibrium, 
temperature, etc.) are important, what the target values are, how the 
factors were controlled, and how well they were controlled.
    5. A description of how the experiment was conducted, including 
preparation of solutions, dilution procedures, sampling procedures, 
monitoring of conditions, etc.
    6. A description of the analytical instrumentation used, how the 
instruments were calibrated, and a summary of the precision for that 
equipment.
    7. A description of the analytical procedures used. If appropriate, 
reference to an ASTM, EPA or other procedure may be used. Otherwise, 
describe how the procedure is done, what is done to measure precision, 
accuracy, recovery, etc., as appropriate.
    8. A description of how data are captured, recorded, and stored.
    9. A description of the equations used and their solutions, 
including a reference to any software used for calculations and/or 
curve-fitting.

        E. Multiple Zone Concentration Measurements (Procedure 5)

    Procedure 5 is the concentration measurement method that can be used 
to determine the fbio for units that are not thoroughly mixed 
and thus have multiple zones of mixing. As with the other procedures, 
proper determination of fbio must be made on a system as it 
would exist under the rule. For purposes of this calculation, the 
biological unit must be divided \1\ into zones with uniform 
characteristics within each zone. The number of zones that is used 
depends on the complexity of the unit. Reference 8, ``Technical Support

[[Page 1147]]

Document for the Evaluation of Aerobic Biological Treatment Units with 
Multiple Mixing Zones,'' is a source for further information concerning 
how to determine the number of zones that should be used for evaluating 
your unit. The following information on the biological unit must be 
available to use this procedure: basic unit variables such as inlet and 
recycle wastewater flow rates, type of agitation, and operating 
conditions; measured representative organic compound concentrations in 
each zone and the inlet and outlet; and estimated mass transfer 
coefficients for each zone.
---------------------------------------------------------------------------

    \1\ This is a mathematical division of the actual unit; not addition 
of physical barriers.
---------------------------------------------------------------------------

    Reference 8 ``Technical Support Document for the Evaluation of 
Aerobic Biological Treatment Units with Multiple Mixing Zones,'' is a 
source for further information concerning how to interpolate the 
biorates for multiple zones. In units with well-characterized 
concentration measurements obtained in an initial evaluation of the 
unit, it may be possible to demonstrate that there is a good correlation 
of the component concentrations with the locations in the multiple-zone 
unit. With this good correlation, it may be possible to accurately 
predict the concentrations in selected zones without actually testing 
each selected zone. This correlation method may be used for units that 
have many zones (greater than 5) or where one of the interior zones is 
not readily accessible for sampling. To use this correlation method of 
estimating zone concentrations, it is necessary to measure the 
concentrations in the inlet unit, the exit unit, and sufficient interior 
units to obtain a correlation of component concentrations with the 
locations. You cannot use this correlation method of estimating selected 
zone concentrations if monitoring of each zone is required, or if the 
accuracy and precision of the correlation is inferior to actual 
individual sampling error. The accuracy and precision of the correlation 
may be improved by increasing the number of locations tested. Because 
the correlation is based on many samples, it should provide an accurate 
representation of a stable operating system.
    The estimated mass transfer coefficient for each compound in each 
zone is obtained from Form II using the characteristics of each zone. A 
computer model may be used. If the Water7 model or the most recent 
update to this model is used, then use Form II-A to calculate KL. The 
TOXCHEM or BASTE model may also be used to calculate KL for the 
biological treatment unit, with the stipulations listed in Procedure 
304B. Compound concentration measurements for each zone are used in Form 
XIII to calculate the fbio. A copy of Form XIII is completed 
for each of the compounds of concern treated in the biological unit.

                      IV. Calculation of Fbio

    At this point, the individual fbios determined by 
the previously explained procedures must be summed to obtain the total 
Fbio. To determine the Fbio multiply each compound 
specific fbio by the compound-specific average mass flow rate 
of the organic compound in the wastewater stream (see regulation for 
instruction on calculation of average mass flow rate). Sum these 
products and divide by the total wastewater stream average mass flow 
rate of organic compounds.
[GRAPHIC] [TIFF OMITTED] TR17JA97.040

M=compound specific average mass flow rate of the organic compounds in 
          the wastewater (Mg/Yr)
n=number of organic compounds in the wastewater

    The Fbio is then used in the applicable compliance 
equations in the regulation to determine if biodegradation may be used 
to comply with the treatment standard without covering and venting to an 
air pollution control device.

 Appendix D to Part 63--Alternative Validation Procedure for EPA Waste 
                         and Wastewater Methods

                            1. Applicability

    This procedure is to be applied exclusively to Environmental 
Protection Agency methods developed by the Office of Water and the 
Office of Solid Waste. Alternative methods developed by any other group 
or agency shall be validated according to the procedures in Sections 5.1 
and 5.3 of Test Method 301, 40 CFR Part 63, Appendix A. For the purposes 
of this appendix, ``waste'' means waste and wastewater.

                              2. Procedure

    This procedure shall be applied once for each waste matrix. Waste 
matrix in the context of this procedure refers to the target compound 
mixture in the waste as well as

[[Page 1172]]

the formulation of the medium in which the target compounds are 
suspended. The owner or operator shall prepare a sampling plan. 
Wastewater samples shall be collected using sampling procedures which 
minimize loss of organic compounds during sample collection and analysis 
and maintain sample integrity. The sample plan shall include procedures 
for determining recovery efficiency of the relevant compounds regulated 
in the applicable subpart. An example of an acceptable sampling plan 
would be one that incorporates similar sampling and sample handling 
requirements to those of Method 25D of 40 CFR part 60, appendix A.

                       2.1. Sampling and Analysis

    2.1.1. For each waste matrix, collect twice the number of samples 
required by the applicable regulation. Designate and label half the 
sample vials the ``spiked'' sample set, and the other half the 
``unspiked'' sample set. Immediately before or immediately after 
sampling (immediately after in the context of this procedure means after 
placing the sample into the sample vial, but before the sample is 
capped, cooled, and shipped to the laboratory for analysis), inject, 
either individually or as a solution, all the target compounds into each 
spiked sample.
    2.1.2. The mass of each spiked compound shall be 40 to 60 percent of 
the mass expected to be present in the waste matrix. If the 
concentration of the target compounds in the waste are not known, the 
mass of each spiked compound shall be 40 to 60 percent of the limit 
allowed in the applicable regulation. Analyze both sets of samples 
(spiked and unspiked) with the chosen method.

                             3. Calculations

    For each pair of spiked and unspiked samples, determine the fraction 
of spiked compound recovered (R) using the following equations.

where:
mr = mass spiked compound measured ([mu] g).
ms = total mass of compound measured in spiked sample ([mu] 
g).
mu = total mass of compound measured in unspiked sample ([mu] 
g).
where:
S = theoretical mass of compound spiked into spiked sample ([mu] g).

                         3.1. Method Evaluation

    In order for the chosen method to be acceptable for a compound, 
0.70[le]R[le]1.30 (R in this case is an average value of all the spiked 
and unspiked sample set R values). If the average R value does not meet 
this criterion for a target compound, the chosen method is not 
acceptable for that compound, and therefore another method shall be 
evaluated for acceptance (by repeating the procedures outlined above 
with another method).

                        3.2. Records and Reports

    Report the average R value in the test report and correct all 
reported measurements made with the method with the calculated R value 
for that compound by using the following equation:
[GRAPHIC] [TIFF OMITTED] TR01JY96.048

                      3.3. Optional Correction Step

    If the applicable regulation allows for correction of the mass of 
the compound in the waste by a published fm value, multiply 
the reported result calculated above with the appropriate fm 
value for that compound.

Appendix E to Part 63--Monitoring Procedure for Nonthoroughly Mixed Open 
 Biological Treatment Systems at Kraft Pulp Mills Under Unsafe Sampling 
                               Conditions

                               I. Purpose

    This procedure is required to be performed in subpart S of this 
part, entitled National Emission Standards for Hazardous Air Pollutants 
from the Pulp and Paper Industry. Subpart S requires this procedure in 
Sec. 63.453(p)(3) to be followed during unsafe sampling conditions when 
it is not practicable to obtain representative samples of hazardous air 
pollutants (HAP) concentrations from an open biological treatment unit. 
It is assumed that inlet and outlet HAP concentrations from the open 
biological treatment unit may be obtained during the unsafe sampling 
conditions. The purpose of this procedure is to estimate the 
concentration of HAP within the open biological treatment unit based on 
information obtained at inlet and outlet sampling locations in units 
that are not thoroughly mixed and, therefore, have different 
concentrations of HAP at different locations within the unit.

[[Page 1173]]

                             II. Definitions

    Biological treatment unit = wastewater treatment unit designed and 
operated to promote the growth of bacteria to destroy organic materials 
in wastewater.

fbio =The fraction of organic compounds in the wastewater 
          biodegraded in a biological treatment unit.
Fe=The fraction of applicable organic compounds emitted from the 
          wastewater to the atmosphere.
K1=First-order biodegradation rate constant, L/g mixed liquor volatile 
          suspended solids (MLVSS)-hr
KL=Liquid-phase mass transfer coefficient, m/s
Ks=Monod biorate constant at half the maximum rate, g/m3

      III. Test Procedure for Determination of fbio for 
    Nonthoroughly Mixed Open Biological Treatment Units Under Unsafe 
                           Sampling Conditions

    This test procedure is used under unsafe sampling conditions that do 
not permit practicable sampling of open biological treatment units 
within the unit itself, but rather relies on sampling at the inlet and 
outlet locations of the unit. This procedure may be used only under 
unsafe sampling conditions to estimate fbio. Once the unsafe 
conditions have passed, then the formal compliance demonstration 
procedures of fbio based upon measurements within the open 
biological treatment unit must be completed.

                   A. Overview of Estimation Procedure

    The steps in the estimation procedure include data collection, the 
estimation of concentrations within the unit, and the use of Form 1 to 
estimate fbio. The data collection procedure consists of two 
separate components. The first data collection component demonstrates 
that the open biological treatment unit can be represented by Monod 
kinetics and characterizes the effectiveness of the open biological 
treatment unit as part of the initial performance test, and the second 
data collection component is used when there are unsafe sampling 
conditions. These two data collection components are used together in a 
data calculation procedure based on a Monod kinetic model to estimate 
the concentrations in each zone of the open biological treatment unit. 
After the first two components of data collection are completed, the 
calculation procedures are used to back estimate the zone 
concentrations, starting with the last zone in the series and ending 
with the first zone.

                     B. Data Collection Requirements

    This method is based upon modeling the nonthoroughly mixed open 
biological treatment unit as a series of well-mixed zones with internal 
recycling between the units and assuming that two Monod biological 
kinetic parameters can be used to characterize the biological removal 
rates in each unit. The data collection procedure consists of two 
separate components. The first data collection component is part of the 
initial performance test, and the second data collection component is 
used during unsafe sampling conditions.

                       1. Initial Performance Test

    The objective of the first data collection component is to 
demonstrate that the open biological treatment unit can be represented 
by Monod kinetics and to characterize the performance of the open 
biological treatment unit. An appropriate value of the biorate constant, 
Ks, is determined using actual sampling data from the open biological 
treatment unit. This is done during the initial performance test when 
the open biological treatment unit is operating under normal conditions. 
This specific Ks value obtained during the initial performance test is 
used in the calculation procedure to characterize the open biological 
treatment unit during unsafe sampling conditions. The following open 
biological treatment unit characterization information is obtained from 
the first component of the data collection procedure:
    (1) The value of the biorate constant, Ks;
    (2) The number and characteristics of each zone in the open 
biological treatment unit (depth, area, characterization parameters for 
surface aeration, submerged aeration rates, biomass concentration, 
concentrations of organic compounds, dissolved oxygen (DO), dissolved 
solids, temperature, and other relevant variables); and
    (3) The recycle ratio of internal recirculation between the zones. 
The number of zones and the above characterization of the zones are also 
used to determine the performance of the unit under the unsafe sampling 
conditions of concern.

           2. Data Collected Under Unsafe Sampling Conditions

    In the second data collection component obtained under unsafe 
sampling conditions, the measured inlet and outlet HAP concentrations 
and the biomass concentration are obtained for the open biological 
treatment unit. After the site specific data collection is completed on 
the day a parameter excursion occurs, the inlet and outlet 
concentrations are used with the prior open biological treatment unit 
characterization to estimate the concentrations of HAP in each zone. The 
following information on the open biological treatment unit must be 
available in the second data collection component:
    (1) Basic unit variables such as inlet and recycle wastewater flow 
rates, type of agitation, and operating conditions;

[[Page 1174]]

    (2) The value of the inlet and outlet HAP concentrations; and
    (3) The biomass concentration in the open biological treatment unit.

 C. One Time Determination of a Single Value of Ks (Initial Performance 
                                  Test)

    A single value of Ks is calculated using Form 3 for each data set 
that is collected during the initial performance test. A single 
composite value of Ks, deemed to be representative of the biological 
unit, is subsequently selected so that the fbio values 
calculated by the procedures in this appendix (using this single value 
of Ks) for the data sets collected during the initial performance test 
are within 10 percent of the fbio value determined by using 
Form 1 with these same data sets. The value of Ks meeting these criteria 
is obtained by the following steps:
    (1) Determine the median of the Ks values calculated for each data 
set;
    (2) Estimate fbio for each data set using the selected Ks 
value (Form 1 and Form 2);
    (3) Calculate fbio for each data set using Form 1; and
    (4) Compare the fbio values obtained in steps (2) and 
(3); if the fbio value calculated using step (2) differs from 
that calculated using step (3) by more than 10 percent, adjust Ks 
(decrease Ks if the fbio value is lower than that calculated 
by Form 1 and vice versa) and repeat this procedure starting at step 
(2). If a negative value is obtained for the values of Ks, then this 
negative kinetic constant may not be used with the Monod model. If a 
negative value of Ks is obtained, this test procedure cannot be used for 
evaluating the performance of the open biological treatment unit.

      D. Confirmation of Monod Kinetics (Initial Performance Test)

    (1) Confirmation that the unit can be represented by Monod kinetics 
is made by identifying the following two items:
    (i) The zone methanol concentrations measured during the initial 
performance test; and
    (ii) The zone methanol concentrations estimated by the Multiple Zone 
Concentrations Calculations Procedure based on inlet and outlet 
concentrations (Column A of Form 2). For each zone, the concentration in 
item 1 is compared to the concentration in item 2.
    (2) For each zone, the estimated value of item 2 must be:
    (i) Within 25 percent of item 1 when item 1 exceeds 8 mg/L; or
    (ii) Within 2 mg/L of item 1 when item 1 is 8 mg/L or less.
    (3) Successful demonstration that the calculated zone concentrations 
meet these criteria must be achieved for 80 percent of the performance 
test data sets.
    (4) If negative values are obtained for the values of K1 and Ks, 
then these negative kinetic constants may not be used with the Monod 
model, even if the criteria are met. If negative values are obtained, 
this test procedure cannot be used for evaluating the performance of the 
open biological treatment unit.

    E. Determination of KL for Each Zone (Unsafe Sampling Conditions)

    (1) A site-specific liquid-phase mass transfer coefficient (KL) must 
be obtained for each zone during the unsafe sampling conditions. Do not 
use a default value for KL. The KL value for each zone must be based on 
the site-specific parameters of the specific unit. The first step in 
using this procedure is to calculate KL for each zone in the unit using 
Form 4. Form 4 outlines the procedure to follow for using mass transfer 
equations to determine KL. Form 4 identifies the appropriate form to use 
for providing the detailed calculations to support the estimate of the 
value of KL. Forms 5 and 6 are used to provide individual compound 
estimates of KL for quiescent and aerated impoundments, respectively. A 
computer model may be used to perform the calculations. If the WATER8 
model or the most recent update to this model is used, then report the 
computer model input parameters that you used as an attachment to Form 
4. In addition, the Bay Area Sewage Toxics Emission (BASTE) model, 
version 3.0, or equivalent upgrade and the TOXCHEM (Environment Canada's 
Wastewater Technology Centre and Environmega, Ltd.) model, version 1.10, 
or equivalent upgrade may also be used to determine KL for the open 
biological treatment unit with the following stipulations:
    (i) The programs must be altered to output a KL value that is based 
on the site-specific parameters of the unit modeled; and
    (ii) The Henry's law value listed in Form 4 must be substituted for 
the existing Henry's law values in the models.
    (2) The Henry's law value listed in Form 4 may be obtained from the 
following sources:
    (i) Values listed by EPA with temperature adjustment if needed;
    (ii) Measured values for the system of concern with temperature 
adjustment; or
    (iii) Literature values of Henry's law values for methanol, adjusted 
for temperature if needed.
    (3) Input values used in the model and corresponding output values 
shall become part of the documentation of the fbio 
determination. The owner or operator should be aware that these models 
may not provide equivalent KL values for some types of units. To obtain 
an equivalent KL value in this situation, the owner or operator shall 
either use the appropriate procedure on Form 4 or adjust the KL value 
from the model to the equivalent KL value as described on Form 4.

[[Page 1175]]

    (4) Report the input parameters that you used in the computer model 
on Forms 5, 6, and 7 as an attachment to Form 4. If you have submerged 
air flow in your unit, you must add the value of KL estimated on Form 7 
to the value of KL obtained with Forms 5 and 6 before using the value of 
KL with Form 2.

    F. Estimation of Zone Concentrations (Unsafe Sampling Conditions)

    Form 2 is used to estimate the zone concentrations of HAP based on 
the inlet and outlet data. The value of Ks entered on the form is that 
single composite value of Ks discussed in section III.C of this 
appendix. This value of Ks is calculated during the Initial Performance 
Test (and subsequently updated, if necessary). A unique value of the 
biorate K1 is entered on line 5 of Form 2, and the inlet concentration 
is estimated in Column A of Form 2. The inlet concentration is located 
in the row of Form 2 corresponding to zone 0. If there are three zones 
in the system, n-3 equals 0 for the inlet concentration row. These 
estimated zone concentrations are then used in Form 1 to estimate f bio 
for the treatment unit.

              G. Quality Control/Quality Assurance (QA/QC)

    A QA/QC plan outlining the procedures used to determine the measured 
inlet and outlet concentrations during unsafe conditions and how the 
zone characterization data were obtained during the initial performance 
test shall be prepared and submitted with the initial performance test 
report. The plan should include, but may not be limited to:
    (1) A description of each of the sampling methods that were used 
(method, procedures, time, method to avoid losses during sampling and 
holding, and sampling procedures) including simplified schematic 
drawings;
    (2) A description of how that biomass was sampled from the 
biotreatment unit, including methods, locations, and times;
    (3) A description of what conditions (DO, temperature, etc.) are 
important, what the target values are in the zones, how the factors were 
controlled, and how they were monitored. These conditions are primarily 
used to establish that the conditions of the initial performance test 
correspond to the conditions of the day in question;
    (4) A description of how each analytical measurement was conducted, 
including preparation of solutions, dilution procedures, sampling 
procedures, monitoring of conditions, etc;
    (5) A description of the analytical instrumentation used, how the 
instruments were calibrated, and a summary of the accuracy and precision 
for each instrument;
    (6) A description of the test methods used to determine HAP 
concentrations and other measurements. Section 63.457(c)(3) specifies 
the test methods that must be used to determine HAP concentrations. 
During unsafe sampling conditions, you do not have to sample over an 
extended period of time or obtain more than one sample at each sample 
point.
    (7) A description of how data are captured, recorded, and stored; 
and
    (8) A description of the equations used and their solutions for 
sampling and analysis, including a reference to any software used for 
calculations and/or curve-fitting.

     IV. Calculation of Individual fbio (Unsafe Sampling 
                               Conditions)

    Use Form 1 with your zone concentration information to estimate the 
value of f bio under unsafe sampling conditions. Form 1 uses measured 
concentrations of HAP in the unit inlet and outlet, and Form 1 also uses 
the estimated concentrations in each zone of the unit obtained from Form 
2. This procedure may be used on an open biological treatment unit that 
has defined zones within the unit. Use Form 1 to determine 
fbio for each open biological treatment unit as it exists 
under subpart S of part 63. The first step in using Form 1 is to 
calculate KL for each zone in the unit using Form 4. Form 7 must also be 
used if submerged aeration is used. After KL is determined using field 
data, obtain the concentrations of the HAP in each zone. In this 
alternative procedure for unsafe sampling conditions, the actual 
measured concentrations of the HAP in each zone are replaced with the 
zone concentrations that are estimated with Form 2. After KL and the 
zone concentrations are determined, Form 1 is used to estimate the 
overall unit Fe and fbio for methanol.
