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, 2019), 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.
PAST PROVISIONS OF THE CODE
Provisions of the Code that are no longer in force and effect as of
the revision date stated on the cover of each volume are not carried.
Code users may find the text of provisions in effect on any given date
in the past by using the appropriate List of CFR Sections Affected
(LSA). For the convenience of the reader, a ``List of CFR Sections
Affected'' is published at the end of each CFR volume. For changes to
the Code prior to the LSA listings at the end of the volume, consult
previous annual editions of the LSA. For changes to the Code prior to
2001, consult the List of CFR Sections Affected compilations, published
for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.
``[RESERVED]'' TERMINOLOGY
The term ``[Reserved]'' is used as a place holder within the Code of
Federal Regulations. An agency may add regulatory information at a
``[Reserved]'' location at any time. Occasionally ``[Reserved]'' is used
editorially to indicate that a portion of the CFR was left vacant and
not accidentally dropped due to a printing or computer error.
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.
What if the material incorporated by reference cannot be found? If
you have any problem locating or obtaining a copy of material listed 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, 8601 Adelphi Road, College Park, MD 20740-6001,
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 Authorities
and Rules. A list of CFR titles, chapters, subchapters, and parts and an
alphabetical list of agencies publishing in the CFR are also included in
this volume.
[[Page vii]]
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.
REPUBLICATION OF MATERIAL
There are no restrictions on the republication of material appearing
in the Code of Federal Regulations.

development facilities as defined in Sec. 63.601.
Sec. 63.601 Definitions.
Terms used in this subpart are defined in Sec. 63.2 of the Clean
Air Act and in this section as follows:
Active gypsum dewatering stack means a gypsum dewatering stack that
is currently receiving gypsum, received gypsum within the last year, or
is part of the facility's water management system. A gypsum dewatering
stack that is considered closed by a state authority is not considered
an active gypsum dewatering stack.
Breakthrough means the point in time when the level of mercury
detected at the outlet of an adsorber system is 90 percent of the
highest concentration allowed to be discharged consistent with the
applicable emission limit.
Cooling pond means a natural or artificial open reservoir that is
primarily used to collect and cool water that comes into direct contact
with raw materials, intermediate products, by-products, waste products,
or finished products from a phosphoric acid manufacturing plant. The
water in the cooling pond is often used at phosphoric acid manufacturing
plants as filter wash water, absorber water for air pollution control
absorbers, and/or to transport phosphogypsum as slurry to a gypsum
dewatering stack(s).
Equivalent P2O5 feed means the quantity of
phosphorus, expressed as phosphorus pentoxide
(P2O5), fed to the process.
Evaporative cooling tower means an open-water, re-circulating device
that uses fans or natural draft to draw or force ambient air through the
device to remove heat from process water by direct contact.
Exceedance means a departure from an indicator range established for
monitoring under this subpart, consistent with any averaging period
specified for averaging the results of the monitoring.
Existing source depends on the date that construction or
reconstruction of an affected source commenced. A wet-process phosphoric
acid process line, superphosphoric acid process line, phosphate rock
dryer, phosphate rock calciner, evaporative cooling tower, or purified
acid process line is an existing source if construction or
reconstruction of the affected source commenced on or before December
27, 1996. A gypsum dewatering stack or cooling pond is an existing
source if it meets one of two criteria:
(1) It was constructed or reconstructed on or before August 19,
2015; or
(2) It was constructed or reconstructed after August 19, 2015 and it
was not required to obtain a permit by a state authority for the
construction or reconstruction.
Gypsum dewatering stack means any defined geographic area associated
with a phosphoric acid manufacturing plant in which gypsum is disposed
of or stored, other than within a fully enclosed building, container, or
tank.
Gypsum dewatering stack system means the gypsum dewatering stack,
together with all pumps, piping, ditches, drainage conveyances, water
control structures, collection pools, cooling ponds, surge ponds,
auxiliary holding ponds, regional holding ponds and any other collection
or conveyance system associated with the transport of gypsum from the
plant to the gypsum dewatering stack, its management at the gypsum
dewatering stack, and the process wastewater return to the phosphoric
acid production or other process.
HAP metals mean those metals and their compounds (in particulate or
volatile form) that are included on the list of hazardous air pollutants
in section 112 of the Clean Air Act. HAP metals include, but are not
limited to: Antimony, arsenic, beryllium, cadmium, chromium, lead,
manganese, nickel, and selenium expressed as particulate matter as
measured by the methods and procedures in this subpart or an approved
alternative method. For the purposes of this subpart, HAP metals (except
mercury) are expressed as particulate matter as measured by Method 5 at
40 CFR part 60, appendix A-3.
New source depends on the date that construction or reconstruction
of an affected source commences. A wet-process phosphoric acid process
line, superphosphoric acid process line, phosphate rock dryer, phosphate
rock calciner, evaporative cooling tower, or
[[Page 13]]
purified acid process line is a new source if construction or
reconstruction of the affected source commenced after December 27, 1996.
A gypsum dewatering stack or cooling pond is a new source if it meets
two criteria:
(1) It was constructed or reconstructed after August 19, 2015; and
(2) It was required to obtain a permit by a state authority for the
construction or reconstruction.
Oxidation reactor means any equipment or step that uses an oxidizing
agent (e.g., nitric acid, ammonium nitrate, or potassium permanganate)
to treat superphosphoric acid.
Phosphate rock calciner means the equipment used to remove moisture
and organic matter from phosphate rock through direct or indirect
heating.
Phosphate rock dryer means the equipment used to reduce the moisture
content of phosphate rock through direct or indirect heating.
Phosphate rock feed means all material entering any phosphate rock
dryer or phosphate rock calciner including moisture and extraneous
material as well as the following ore materials: Fluorapatite,
hydroxylapatite, chlorapatite, and carbonateapatite.
Purified phosphoric acid process line means any process line that
uses a HAP as a solvent in the separation of impurities from the product
acid for the purposes of rendering that product suitable for industrial,
manufacturing, or food grade uses. A purified phosphoric acid process
line includes: solvent extraction process equipment, solvent stripping
and recovery equipment, seal tanks, carbon treatment equipment, cooling
towers, storage tanks, pumps, and process piping.
Raffinate stream means the aqueous stream containing the impurities
that are removed during the purification of wet-process phosphoric acid
using solvent extraction.
Research and development facility means research or laboratory
operations 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 where the
facility is not engaged in the manufacture of products for commercial
sale in commerce or other off-site distribution, except in a de minimis
manner.
Rim ditch (cell) building technique means a gypsum dewatering stack
construction technique that utilizes inner and outer dikes to direct
gypsum slurry flow around the perimeter of the stack before directing
the flow and allowing settling of finer materials into the settling
compartment. For the purpose of this definition, the rim ditch (cell)
building technique includes the compartment startup phase when gypsum is
deposited directly into the settling compartment in preparation for
ditch construction as well as the step-in or terminal phases when most
solids must be directed to the settling compartment prior to stack
closure. Decant return ditches are not rim ditches.
Shutdown commences when feed materials cease to be added to an
affected source and ends when the affected source is deactivated,
regardless of whether feed material is present in the affected source.
Startup commences when any feed material is first introduced into an
affected source and ends when feed material is fully loaded into the
affected source.
Superphosphoric acid process line means any process line that
concentrates wet-process phosphoric acid to 66 percent or greater
P2O5 content by weight. A superphosphoric acid
process line includes: evaporators, hot wells, acid sumps, oxidation
reactors, and cooling tanks.
Total fluorides means elemental fluorine and all fluoride compounds,
including the HAP HF, as measured by reference methods specified in 40
CFR part 60, appendix A, Method 13 A or B, or by equivalent or
alternative methods approved by the Administrator pursuant to Sec.
63.7(f).
Wet-process phosphoric acid process line means any process line
manufacturing phosphoric acid by reacting phosphate rock and acid. A
wet-process phosphoric acid process line includes: reactors, filters,
evaporators, and hot wells.

the surface area of the gypsum pond associated with the active gypsum
dewatering stack by using a rim ditch (cell) building technique or other
building technique.
[[Page 16]]
(v) For at least one gypsum dewatering stack that is considered part
of your gypsum dewatering stack system, you may choose to apply slaked
lime to the active gypsum dewatering stack surfaces. If you choose this
control measure, then you must include in the plan the method used to
determine the specific locations slaked lime is applied. The plan must
also include the methods used to determine the quantity of, and when to
apply, slaked lime (e.g., slaked lime may be applied to achieve a state

(vi) For at least one gypsum dewatering stack that is considered
part of your gypsum dewatering stack system, you may choose to apply
soil caps and vegetation, or a synthetic cover, to a portion of side
slopes of the active gypsum dewatering stack. If you choose this control
measure, then you must include in the plan the method used to determine
the specific locations of soil caps and vegetation, or synthetic cover;
and specify the acreage and locations where soil caps and vegetation, or
synthetic cover, is applied. The plan must also include a schedule
describing when soil caps and vegetation, or synthetic cover, is to be
applied.
(vii) For all gypsum dewatering stacks that are considered part of
your gypsum dewatering stack system, you may choose to establish closure
requirements that at a minimum, contain requirements for the specified
items in paragraphs (e)(3)(vii)(A) and (B) of this section.
(A) A specific trigger mechanism for when you must begin the closure
process on the gypsum dewatering stack; and
(B) A requirement to install a final cover. For purposes of this
paragraph, final cover means the materials used to cover the top and
sides of a gypsum dewatering stack upon closure.
(4) You must submit your plan for approval to the Administrator at
least 6 months prior to the compliance date specified in Sec.
63.602(d), or with the permit application for modification,
construction, or reconstruction. The plan must include details on how
you will implement and show compliance with the control technique(s)
that you have selected to use. The Administrator will approve or
disapprove your plan within 90 days after receipt of the plan. To change
any of the information submitted in the plan, you must submit a revised
plan 60 days before the planned change is to be implemented in order to
allow time for review and approval by the Administrator before the
change is implemented.
(f) Beginning on August 19, 2015, during periods of startup and
shutdown (as defined in Sec. 63.601), you must comply with the work
practice specified in this paragraph in lieu of the emission limits
specified in paragraph (a) of this section. During periods of startup
and shutdown, you must operate any control device(s) being used at the
affected source, monitor the operating parameters specified in Table 3
of this subpart, and comply with the operating limits specified in Table
4 of this subpart.
Sec. Sec. 63.603-63.604 [Reserved]
Sec. 63.605 Operating and monitoring requirements.
(a) For each wet-process phosphoric acid process line or
superphosphoric acid process line subject to the provisions of this
subpart, you must comply with the monitoring requirements specified in
paragraphs (a)(1) and (2) of this section.
(1) Install, calibrate, maintain, and operate a continuous
monitoring system (CMS) according to your site-specific monitoring plan
specified in Sec. 63.608(c). The CMS must have an accuracy of 5 percent over its operating range and must determine
and permanently record the mass flow of phosphorus-bearing material fed
to the process.
(2) Maintain a daily record of equivalent P2O5
feed. Calculate the equivalent P2O5 feed by
determining the total mass rate, in metric ton/hour of phosphorus
bearing feed, using the monitoring system specified in paragraph (a)(1)
of this section and the procedures specified in Sec. 63.606(f)(3).
(b) For each phosphate rock dryer or phosphate rock calciner subject
to the provisions of this subpart, you must
[[Page 17]]
comply with the monitoring requirements specified in paragraphs (b)(1)
and (2) of this section.
(1) Install, calibrate, maintain, and operate a CMS according to
your site-specific monitoring plan specified in Sec. 63.608(c). The CMS
must have an accuracy of 5 percent over its
operating range and must determine and permanently record either:
(i) The mass flow of phosphorus-bearing feed material to the
phosphate rock dryer or calciner, or
(ii) The mass flow of product from the phosphate rock dryer or
calciner.
(2) Maintain the records specified in paragraphs (b)(2)(i) and (ii)
of this section.
(i) If you monitor the mass flow of phosphorus-bearing feed material
to the phosphate rock dryer or calciner as specified in paragraph
(b)(1)(i) of this section, maintain a daily record of phosphate rock
feed by determining the total mass rate in metric tons/hour of
phosphorus-bearing feed.
(ii) If you monitor the mass flow of product from the phosphate rock
dryer or calciner as specified in paragraph (b)(1)(ii) of this section,
maintain a daily record of product by determining the total mass rate in
metric ton/hour of product.
(c) For each purified phosphoric acid process line, you must comply
with the monitoring requirements specified in paragraphs (c)(1) and (2)
of this section.
(1) Install, calibrate, maintain, and operate a CMS according to
your site-specific monitoring plan specified in Sec. 63.608(c). The CMS
must continuously measure and permanently record the stack gas exit
temperature for each chiller stack.
(2) Measure and record the concentration of methyl isobutyl ketone
in each product acid stream and each raffinate stream once each day.
(d) If you use a control device(s) to comply with the emission
limits specified in Table 1 or 2 of this subpart, you must install a
continuous parameter monitoring system (CPMS) and comply with the
requirements specified in paragraphs (d)(1) through (5) of this section.
(1) You must monitor the operating parameter(s) applicable to the
control device that you use as specified in Table 3 to this subpart and
establish the applicable limit or range for the operating parameter
limit as specified in paragraphs (d)(1)(i) and (ii) of this section, as
applicable.
(i) Except as specified in paragraph (d)(1)(ii) of this section,
determine the value(s) as the arithmetic average of operating parameter
measurements recorded during the three test runs conducted for the most
recent performance test.
(ii) If you use an absorber or a wet electrostatic precipitator to
comply with the emission limits in Table 1 or 2 to this subpart and you
monitor pressure drop across the absorber or secondary voltage for a wet
electrostatic precipitator, you must establish allowable ranges using
the methodology specified in paragraphs (d)(1)(ii)(A) and (B) of this
section.
(A) The allowable range for the daily averages of the pressure drop
across an absorber and of the flow rate of the absorber liquid to each
absorber in the process absorbing system, or secondary voltage for a wet
electrostatic precipitator, is 20 percent of the
baseline average value determined in paragraph (d)(1)(i) of this
section. The Administrator retains the right to reduce the 20 percent adjustment to the baseline average values of
operating ranges in those instances where performance test results
indicate that a source's level of emissions is near the value of an
applicable emissions standard. However, the adjustment must not be
reduced to less than 10 percent under any
instance.
(B) As an alternative to paragraph (d)(1)(ii)(A) of this section,
you may establish allowable ranges for the daily averages of the
pressure drop across an absorber, or secondary voltage for an
electrostatic precipitator, for the purpose of assuring compliance with
this subpart using the procedures described in this paragraph. You must
establish the allowable ranges based on the baseline average values
recorded during previous performance tests, or the results of
performance tests conducted specifically for the purposes of this
paragraph. You must conduct all performance tests using the methods
specified in Sec. 63.606. You must certify that the control devices and
processes have not been modified since the date of the
[[Page 18]]
performance test from which you obtained the data used to establish the
allowable ranges. When a source using the methodology of this paragraph
is retested, you must determine new allowable ranges of baseline average
values unless the retest indicates no change in the operating parameters
outside the previously established ranges.
(2) You must monitor, record, and demonstrate continuous compliance
using the minimum frequencies specified in Table 4 to this subpart.
(3) You must comply with the calibration and quality control
requirements that are applicable to the operating parameter(s) you
monitor as specified in Table 5 to this subpart.
(4) If you use a non-regenerative adsorption system to achieve the
mercury emission limits specified in Table 1 or 2 to this subpart, you
must comply with the requirements specified in paragraph (e) of this
section.
(5) If you use a sorbent injection system to achieve the mercury
emission limits specified in Table 1 or 2 to this subpart and you use a
fabric filter to collect the associated particulate matter, the system
must meet the requirements for fabric filters specified in paragraph (f)
of this section.
(e) If you use a non-regenerative adsorption system to achieve the
mercury emission limits specified in Table 1 or 2 to this subpart, you
must comply with the requirements specified in paragraphs (e)(1) through
(3) of this section.
(1) Determine the adsorber bed life (i.e., the expected life of the
sorbent in the adsorption system) using the procedures specified in
paragraphs (e)(1)(i) through (iv) of this section.
(i) If the adsorber bed is expected (designed) to have a life of
less than 2 years, determine the outlet concentration of mercury on a
quarterly basis until breakthrough occurs for the first three adsorber
bed change-outs. The adsorber bed life shall equal the average length of
time between each of the three change-outs.
(ii) If the adsorber bed is expected (designed) to have a life of 2
years or greater, determine the outlet concentration of mercury on a
semi-annual basis until breakthrough occurs for the first two adsorber
bed change-outs. The adsorber bed life must equal the average length of
time between each of the two change-outs.
(iii) If more than one adsorber is operated in parallel, or there
are several identical operating lines controlled by adsorbers, you may
determine the adsorber bed life by measuring the outlet concentration of
mercury from one of the adsorbers or adsorber systems rather than
determining the bed life for each adsorber.
(iv) The adsorber or adsorber system you select for the adsorber bed
life test must have the highest expected inlet gas mercury concentration
and the highest operating rate of any adsorber in operation at the
affected source. During the test to determine adsorber bed life, you
must use the fuel that contains the highest level of mercury in any
fuel-burning unit associated with the adsorption system being tested.
(2) You must replace the sorbent in each adsorber on or before the
end of the adsorbent bed life, calculated in paragraph (e)(1) of this
section.
(3) You must re-establish the adsorber bed life if the sorbent is
replaced with a different brand or type, or if any process changes are
made that would lead to a shorter bed lifetime.
(f) Beginning August 19, 2016, if you use a fabric filter system to
comply with the emission limits specified in Table 1 or 2 to this
subpart, then the fabric filter must be equipped with a bag leak
detection system that is installed, calibrated, maintained, and
continuously operated according to the requirements in paragraphs (f)(1)
through (10) of this section.
(1) Install a bag leak detection sensor(s) in a position(s) that
will be representative of the relative or absolute particulate matter
loadings for each exhaust stack, roof vent, or compartment (e.g., for a
positive-pressure fabric filter) of the fabric filter.
(2) Use a bag leak detection system certified by the manufacturer to
be capable of detecting particulate matter emissions at concentrations
of 1 milligram per actual cubic meter (0.00044 grains per actual cubic
feet) or less.
(3) Use a bag leak detection system equipped with a device to
continuously
[[Page 19]]
record the output signal from the system sensor.
(4) Use a bag leak detection system equipped with a system that will
trigger an alarm when an increase in relative particulate matter
emissions over a preset level is detected. The alarm must be located
such that the alert is observed readily by plant operating personnel.
(5) Install a bag leak detection system in each compartment or cell
for positive-pressure fabric filter systems that do not duct all
compartments or cells to a common stack. Install a bag leak detector
downstream of the fabric filter if a negative-pressure or induced-air
filter system is used. If multiple bag leak detectors are required, the
system's instrumentation and alarm may be shared among detectors.
(6) Calibration of the bag leak detection system must, at a minimum,
consist of establishing the baseline output level by adjusting the range
and the averaging period of the device and establishing the alarm set
points and the alarm delay time.
(7) After initial adjustment, you must not adjust the sensitivity or
range, averaging period, alarm set points, or alarm delay time except as
established in your site-specific monitoring plan required in Sec.
63.608(c). In no event may the sensitivity be increased more than 100
percent or decreased by more than 50 percent over a 365-day period
unless such adjustment follows a complete inspection of the fabric
filter system that demonstrates that the system is in good operating
condition.
(8) Operate and maintain each fabric filter and bag leak detection
system such that the alarm does not sound more than 5 percent of the
operating time during a 6-month period. If the alarm sounds more than 5
percent of the operating time during a 6-month period, it is considered
an operating parameter exceedance. Calculate the alarm time (i.e., time
that the alarm sounds) as specified in paragraphs (f)(8)(i) through
(iii) of this section.
(i) If inspection of the fabric filter demonstrates that corrective
action is not required, the alarm duration is not counted in the alarm
time calculation.
(ii) If corrective action is required, each alarm time is counted as
a minimum of 1 hour.
(iii) If it takes longer than 1 hour to initiate corrective action,
each alarm time is counted as the actual amount of time taken to
initiate corrective action.
(9) If the alarm on a bag leak detection system is triggered, you
must initiate procedures within 1 hour of an alarm to identify the cause
of the alarm and then initiate corrective action, as specified in Sec.
63.608(d)(2), no later than 48 hours after an alarm. Failure to take
these actions within the prescribed time periods is considered a
violation.
(10) Retain records of any bag leak detection system alarm,
including the date, time, duration, and the percent of the total
operating time during each 6-month period that the alarm sounds, with a
brief explanation of the cause of the alarm, the corrective action
taken, and the schedule and duration of the corrective action.
(g) If you choose to directly monitor mercury emissions instead of
using CPMS as specified in paragraph (d) of this section, then you must
install and operate a mercury CEMS in accordance with Performance
Specification 12A of appendix B to part 60 of this chapter, or a sorbent
trap-based integrated monitoring system in accordance with Performance
Specification 12B of appendix B to part 60 of this chapter. You must
continuously monitor mercury emissions as specified in paragraphs (g)(1)
through (4) of this section.
(1) The span value for any mercury CEMS must include the intended
upper limit of the mercury concentration measurement range during normal
operation, which may be exceeded during other short-term conditions
lasting less than 24 consecutive operating hours. However, the span
should be at least equivalent to approximately two times the emissions
standard. You may round the span value to the nearest multiple of 10
micrograms per cubic meter of total mercury.
(2) You must operate and maintain each mercury CEMS or sorbent trap-
based integrated monitoring system
[[Page 20]]
according to the quality assurance requirements specified in Procedure 5
of appendix F to part 60 of this chapter.
(3) You must conduct relative accuracy testing of mercury monitoring
systems, as specified in Performance Specification 12A, Performance
Specification 12B, or Procedure 5 of appendix B to part 60 of this
chapter, at normal operating conditions.
(4) If you use a mercury CEMS, you must install, operate, calibrate,
and maintain an instrument for continuously measuring and recording the
exhaust gas flow rate to the atmosphere according to your site-specific
monitoring plan specified in Sec. 63.608(c).

conditions under which the facility expects to operate (regardless of
the frequency of the conditions); and
(ii) Are likely to most challenge the emissions control measures of
the facility with regard to meeting the applicable emission standards,
but without creating an unsafe condition. Operations during startup,
shutdown, and malfunction do not constitute representative (normal)
operating conditions for purposes of conducting a performance test.
(2) You must record the process information that is necessary to
document the operating conditions during the test and include in such
record an explanation to support that such conditions represent
representative (normal) conditions. Upon request, you must make
available to the Administrator such records as may be necessary to
determine the conditions of performance tests.
(e) In conducting all performance tests, you must use as reference
methods and procedures the test methods in 40 CFR part 60, appendix A,
or other methods and procedures as specified in this section, except as
provided in Sec. 63.7(f).

K = Conversion factor, 1000 grams/kilogram (453.6 grams/pound).
(2) Use Method 5 at 40 CFR part 60, appendix A-3 to determine the
particulate matter concentration (C) and volumetric flow rate (Q) of the
effluent gas. Except as specified in paragraph (h) of this section, the
sampling time and sample volume for each run must be at least 60 minutes
and 0.85 dry standard cubic meter (30 dry standard cubic feet).
(3) Use the CMS described in Sec. 63.605(b) to determine the
phosphate rock feed rate (P) for each run.
(h) To demonstrate compliance with the particulate matter standards
for phosphate rock calciners specified in Tables 1 and 2 to this
subpart, you must use Method 5 at 40 CFR part 60, appendix A-3 to
determine the particulate matter concentration. The sampling volume for
each test run must be at least 1.70 dry standard cubic meter.
(i) To demonstrate compliance with the mercury emission standards
for phosphate rock calciners specified in Tables 1 and 2 to this
subpart, you must use Method 30B at 40 CFR part 60, appendix A-8 to
determine the mercury concentration, unless you use a CEMS to
demonstrate compliance. If you use a non-regenerative adsorber to
control mercury emissions, you must use this test method to determine
the expected bed life as specified in Sec. 63.605(e)(1).
(j) If you choose to monitor the mass flow of product from the
phosphate rock dryer or calciner as specified in Sec. 63.605(b)(1)(ii),
you must either:
(1) Simultaneously monitor the feed rate and output rate of the
phosphate rock dryer or calciner during the performance test, or

contents of the phosphate rock dryer or calciner during the performance
test and calculate the corresponding phosphate rock dryer or calciner
input rate.
(k) For sorbent injection systems, you must conduct the performance
test at the outlet of the fabric filter used for sorbent collection. You
must monitor and record operating parameter values for the fabric filter
during the performance test. If the sorbent is replaced with a different
brand or type of sorbent than was used during the performance test, you
must conduct a new performance test.
(l) If you use a mercury CEMS as specified in Sec. 63.605(g), or
paragraph (i) of this section, you must demonstrate initial compliance
based on the first 30 operating days during which you operate the
affected source using a CEMS. You must obtain hourly mercury
concentration and stack gas volumetric flow rate data.
(m) If you use a CMS, you must conduct a performance evaluation, as
specified in Sec. 63.8(e), in accordance with your site-specific
monitoring plan in Sec. 63.608(c). For fabric filters, you must conduct
a performance evaluation of the bag leak detection system consistent

particulate matter emissions, range, averaging period, and alarm set
points during the performance test.
Sec. 63.607 Notification, recordkeeping, and reporting requirements.
(a) You must comply with the notification requirements specified in
Sec. 63.9. During the most recent performance test, if you demonstrate
compliance with the emission limit while operating your control device
outside the previously established operating limit, you must establish a
new operating limit based on that most recent performance test and
notify the Administrator that the operating limit changed based on data
collected during the most recent performance test. When a source is
retested and the performance test results are submitted to the
Administrator pursuant to paragraph (b)(1) of this section, Sec.
63.7(g)(1), or Sec. 63.10(d)(2), you must indicate whether the
operating limit is based on the new performance test or the previously
established limit. Upon establishment of a new operating limit, you must
thereafter operate under the new operating limit. If the Administrator
determines
[[Page 23]]
that you did not conduct the compliance test in accordance with the
applicable requirements or that the operating limit established during
the performance test does not correspond to representative (normal)
conditions, you must conduct a new performance test and establish a new
operating limit.
(b) You must comply with the reporting and recordkeeping
requirements in Sec. 63.10 as specified in paragraphs (b)(1) through

procedures in Sec. 63.605(d)(1)(ii)(B), certify to the Administrator
annually that the control devices and processes have not been modified
since the date of the performance test from which you obtained the data
used to establish the allowable ranges.
(v) Each time a gypsum dewatering stack is closed, certify to the
Administrator within 90 days of closure, that the final cover of the
closed gypsum dewatering stack is a drought resistant vegetative cover
that includes a barrier soil layer that will sustain vegetation.
(3) As required by Sec. 63.10(e)(3), you must submit an excess
emissions report for any exceedance of an emission limit, work practice
standard, or operating parameter limit if the total duration of the
exceedances for the reporting period is 1 percent of the total operating
time for the reporting period or greater. The report must contain the
information specified in Sec. 63.10 and paragraph (b)(4) of this
section. When exceedances of an emission limit or operating parameter
have not occurred, you must include such information in the report. You
must submit the report semiannually and the report must be delivered or
postmarked by the 30th day following the end of the calendar half. If
you report exceedances, you must submit the excess emissions report
quarterly until a request to reduce reporting frequency is approved as
described in Sec. 63.10(e)(3)(ii).
(4) In the event that an affected unit fails to meet an applicable
standard, record and report the following information for each failure:
(i) The date, time and duration of the failure.
(ii) A list of the affected sources or equipment for which a failure
occurred.
(iii) An estimate of the volume of each regulated pollutant emitted
over any emission limit.
(iv) A description of the method used to estimate the emissions.
(v) A record of actions taken to minimize emissions in accordance
with Sec. 63.608(b), and any corrective actions taken to return the
affected unit to its normal or usual manner of operation.
(5) You must submit a summary report containing the information
specified in Sec. 63.10(e)(3)(vi). You must submit the summary report
semiannually and the report must be delivered or postmarked by the 30th
day following the end of the calendar half.
(c) Your records must be in a form suitable and readily available
for expeditious review. You must keep each record for 5 years following
the date of each recorded action. You must keep each record on site, or
accessible from a central location by computer or other means that
instantly provides access at the site, for at least 2 years
[[Page 24]]
after the date of each recorded action. You may keep the records off
site for the remaining 3 years.
(d) In computing averages to determine compliance with this subpart,
you must exclude the monitoring data specified in paragraphs (d)(1) and
(2) of this section.
(1) Periods of non-operation of the process unit;
(2) Periods of no flow to a control device; and any monitoring data
recorded during CEMS or continuous parameter monitoring system (CPMS)
breakdowns, out-of-control periods, repairs, maintenance periods,
instrument adjustments or checks to maintain precision and accuracy,
calibration checks, and zero (low-level), mid-level (if applicable), and
high-level adjustments.
(e) Within 60 days after the date of completing each performance
test (as defined in Sec. 63.2) required by this subpart, you must
submit the results of the performance tests, including any associated
fuel analyses, following the procedure specified in either paragraph
(e)(1) or (2) of this section.

Sec. 63.608 General requirements and applicability of general
provisions of this part.
(a) You must comply with the general provisions in subpart A of this
part as specified in appendix A to this subpart.
(b) At all times, you must operate and maintain any affected source,
including associated air pollution control equipment and monitoring
equipment, in a manner consistent with safety and good air pollution
control practices for minimizing emissions. The general duty to minimize
emissions does not require you to make any further efforts to reduce
emissions if levels required by this standard have been achieved.
Determination by the Administrator of whether a source is operating in
compliance with operation and maintenance requirements will be based on
information available to the Administrator that may include, but is not
limited to, monitoring results, review of operation and maintenance
procedures, review of operation and maintenance records, and inspection
of the source.
(c) For each CMS (including CEMS or CPMS) used to demonstrate
compliance with any applicable emission limit or work practice, you must
develop, and submit to the Administrator for approval upon request, a
site-specific monitoring plan according to the requirements specified in
paragraphs (c)(1) through (3) of this section. You must submit the site-
specific monitoring plan, if requested by the Administrator, at least 60
days before the initial performance evaluation of the CMS. The
requirements of this paragraph also apply if a petition is made to the
Administrator for alternative monitoring parameters under Sec. 63.8(f).
(1) You must include the information specified in paragraphs
(c)(1)(i) through (vi) of this section in the site-specific monitoring
plan.
(i) Location of the CMS sampling probe or other interface. You must
include a justification demonstrating that the sampling probe or other
interface is 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).
(ii) Performance and equipment specifications for the sample
interface, the pollutant concentration or parametric signal analyzer,
and the data collection and reduction systems.
(iii) Performance evaluation procedures and acceptance criteria
(e.g., calibrations).
(iv) Ongoing operation and maintenance procedures in accordance with
the general requirements of Sec. 63.8(c)(1)(ii), (c)(3), (c)(4)(ii),
and Table 4 to this subpart.
(v) Ongoing data quality assurance procedures in accordance with the
general requirements of Sec. 63.8(d)(1) and (2) and Table 5 to this
subpart.
(vi) Ongoing recordkeeping and reporting procedures in accordance
with the general requirements of Sec. 63.10(c), (e)(1), and (e)(2)(i).
(2) You must include a schedule for conducting initial and
subsequent performance evaluations in the site-specific monitoring plan.
(3) You must keep the site-specific monitoring plan on site for the
life of the affected source or until the affected source is no longer
subject to the provisions of this part, to be made available for
inspection, upon request, by the Administrator. If you revise the site-
specific monitoring plan, you must keep previous (i.e., superseded)
versions of the plan on site to be made available for inspection, upon
request, by the Administrator, for a period of 5 years after each
revision to the plan. You must include the program of corrective action
required under Sec. 63.8(d)(2) in the plan.
(d) For each bag leak detection system installed to comply with the
requirements specified in Sec. 63.605(f), you must include the
information specified
[[Page 26]]
in paragraphs (d)(1) and (2) of this section in the site-specific
monitoring plan specified in paragraph (c) of this section.
(1) Performance evaluation procedures and acceptance criteria (e.g.,
calibrations), including how the alarm set point will be established.
(2) A corrective action plan describing corrective actions to be
taken and the timing of those actions when the bag leak detection alarm
sounds. Corrective actions may include, but are not limited to, the
actions specified in paragraphs (d)(2)(i) through (vi) of this section.
(i) Inspecting the fabric filter for air leaks, torn or broken bags
or filter media, or any other conditions that may cause an increase in
regulated material 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 fabric filter compartment.
(v) Cleaning the bag leak detection system probe or otherwise
repairing the bag leak detection system.
(vi) Shutting down the process controlled by the fabric filter.
(e) If you use blower design capacity to determine the gas flow rate
through the absorber for use in the liquid-to-gas ratio as specified in
Table 3 to this subpart, then you must include in the site-specific
monitoring plan specified in paragraph (c) of this section calculations
showing how you determined the maximum possible gas flow rate through
the absorber based on the blower's specifications (including any
adjustments you made for pressure drop).
(f) If you use a regression model to determine the gas flow rate
through the absorber for use in the liquid-to-gas ratio as specified in
Table 3 to this subpart, then you must include in the site-specific
monitoring plan specified in paragraph (c) of this section the
calculations that were used to develop the regression model, including
the calculations you use to convert amperage of the blower to brake
horsepower. You must describe any constants included in the equations
(e.g., efficiency, power factor), and describe how these constants were
determined. If you want to change a constant in your calculation, then
you must conduct a regression model verification to confirm the new
value of the constant. In addition, the site-specific monitoring plan
must be updated annually to reflect the data used in the annual
regression model verification that is described in Table 3 to this
subpart.

----------------------------------------------------------------------------------------------------------------
\a\ To monitor an operating parameter that is not specified in this table (including process-specific techniques
not specified in this table to determine gas flow rate through an absorber), you must request, on a site-
specific basis, an alternative monitoring method under the provisions of 40 CFR 63.8(f).
\b\ For new sources that commence construction or reconstruction after August 19, 2015, the compliance date is
immediately upon startup. For existing sources, and new sources that commence construction or reconstruction
after December 27, 1996, and on or before August 19, 2015, if your absorber is designed and operated with
pressure drops of 5 inches of water column or less, then the compliance date is August 19, 2018. In the
interim, for existing sources, and new sources that commence construction or reconstruction after December 27,
1996, and on or before August 19, 2015, with an absorber designed and operated with pressure drops of 5 inches
of water column or less, you must comply with one of the following: (i) The monitoring requirements in this
Table 3 for absorbers designed and operated with pressure drops of 5 inches of water column or less; (ii) the
applicable monitoring provisions included in a permit issued under 40 CFR part 70 to assure compliance with
subpart AA; (iii) the applicable monitoring provisions of an Alternative Monitoring Plan approved pursuant to
Sec. 63.8(f); or (iv) install CPMS for pressure at the gas stream inlet and outlet of the absorber, and
monitor pressure drop through the absorber.
\c\ If you select this option, then you must comply with Sec. 63.608(e). The option to use blower design
capacity is intended to establish the maximum possible gas flow through the absorber; and is available
regardless of the location of the blower (influent or effluent), as long as the gas flow rate through the
absorber can be established. Establish the minimum liquid-to-gas ratio operating limit by dividing the minimum
liquid flow rate to the absorber (determined during a performance test) by the maximum possible gas flow rate
through the absorber (determined using blower design capacity).
\d\ If you select this option, then you must comply with Sec. 63.608(f). The regression model must be
developed using direct measurements of gas flow rate, and design fan curves that correlate gas flow rate to
static pressure (i.e., fan suction pressure) and brake horsepower of the blower. You must conduct an annual
regression model verification using direct measurements of gas flow rate to ensure the correlation remains
accurate. Direct measurements of gas flow rate used to develop or verify regression models may be collected
during, or separately from, the annual performance testing that is required in Sec. 63.606(b).

Sec. 63.620 Applicability.
(a) Except as provided in paragraphs (c) and (d) of this section,
you are subject to the requirements of this subpart if you own or
operate a phosphate fertilizer production plant that is a major source
as defined in Sec. 63.2. You must comply with the emission limitations,
work practice standards, and operating parameter requirements specified
in this subpart at all times.
(b) The requirements of this subpart apply to emissions of hazardous
air pollutants (HAP) emitted from the following affected sources at a
phosphate fertilizer production plant:
(1) Each phosphate fertilizer process line (e.g., diammonium and/or
monoammonium phosphate process line).
(2) Each granular triple superphosphate process line.
(3) Each granular triple superphosphate storage building.
(4) Evaporative cooling tower.
(c) The requirements of this subpart do not apply to a phosphate
fertilizer production plant that is an area source as defined in Sec.
63.2.
(d) The provisions of this subpart do not apply to research and
development facilities as defined in Sec. 63.621.
Sec. 63.621 Definitions.
Terms used in this subpart are defined in Sec. 63.2 of the Clean
Air Act and in this section as follows:
Diammonium and/or monoammonium phosphate process line means any
process line manufacturing granular diammonium and/or monoammonium
phosphate by reacting ammonia with phosphoric acid that has been derived
from or manufactured by reacting phosphate rock and acid. A diammonium
and/or monoammonium phosphate process line includes: Reactors,
granulators, dryers, coolers, screens, and mills.
Equivalent P2O5 feed means the quantity of
phosphorus, expressed as phosphorus pentoxide
(P2O5), fed to the process.
Equivalent P2O5 stored means the quantity of
phosphorus, expressed as phosphorus pentoxide, being cured or stored in
the affected facility.
Evaporative cooling tower means an open-water, re-circulating device
that uses fans or natural draft to draw or force ambient air through the
device to remove heat from process water by direct contact.
Exceedance means a departure from an indicator range established for
monitoring under this subpart, consistent with any averaging period
specified for averaging the results of the monitoring.
Existing source depends on the date that construction or
reconstruction of an affected source commenced. A phosphate fertilizer
process line (e.g., diammonium and/or monoammonium phosphate process
line), granular triple superphosphate process line, or granular triple
superphosphate storage is an existing source if construction or
reconstruction of the affected source commenced on or before December
27, 1996.
Fresh granular triple superphosphate means granular triple
superphosphate produced within the preceding 72 hours.
Granular triple superphosphate process line means any process line,
not including storage buildings, that manufactures granular triple
superphosphate by reacting phosphate rock with phosphoric acid. A
granular triple superphosphate process line includes: mixers, curing
belts (dens), reactors, granulators, dryers, coolers, screens, and
mills.
Granular triple superphosphate storage building means any building
curing or storing fresh granular triple superphosphate. A granular
triple superphosphate storage building includes: storage or curing
buildings, conveyors, elevators, screens, and mills.
New source depends on the date that construction or reconstruction
of an affected source commences. A phosphate fertilizer process line
(e.g., diammonium and/or monoammonium phosphate process line), granular
triple
[[Page 34]]
superphosphate process line, or granular triple superphosphate storage
is a new source if construction or reconstruction of the affected source
commenced after December 27, 1996.
Phosphate fertilizer process line means any process line that
manufactures a granular phosphate fertilizer by reacting phosphoric acid
with ammonia. A phosphate fertilizer process line includes: reactors,
granulators, dryers, coolers, screens, and mills.
Phosphate fertilizer production plant means any production plant
that manufactures a granular phosphate fertilizer by reacting phosphoric
acid with ammonia.
Research and development facility means research or laboratory
operations 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 where the
facility is not engaged in the manufacture of products for commercial
sale in commerce or other off-site distribution, except in a de minimis
manner.
Shutdown commences when feed materials cease to be added to an
affected source and ends when the affected source is deactivated,
regardless of whether feed material is present in the affected source.
Startup commences when any feed material is first introduced into an
affected source and ends when feed material is fully loaded into the
affected source.
Total fluorides means elemental fluorine and all fluoride compounds,
including the HAP hydrogen fluoride, as measured by reference methods
specified in 40 CFR part 60, appendix A, Method 13 A or B, or by

Sec. 63.622 Standards and compliance dates.
(a) On and after the dates specified in paragraphs (a)(1) through
(3) of this section, for each phosphate fertilizer process line (e.g.,
diammonium and/or monoammonium phosphate process line), granular triple
superphosphate process line, and granular triple superphosphate storage
building, you must comply with the emission limits as specified in
paragraphs (a)(1) through (3) of this section. If a process line
contains more than one emission point, you must sum the emissions from
all emission points in a process line to determine compliance with the
specified emission limits.
(1) For each existing phosphate fertilizer process line (e.g.,
diammonium and/or monoammonium phosphate process line), granular triple
superphosphate process line, and granular triple superphosphate storage
building that commenced construction or reconstruction on or before
December 27, 1996, you must comply with the emission limits specified in
Table 1 to this subpart beginning on June 10, 2002.
(2) For each new phosphate fertilizer process line (e.g., diammonium
and/or monoammonium phosphate process line), granular triple
superphosphate process line, and granular triple superphosphate storage
building that commences construction or reconstruction after December
27, 1996 and on or before August 19, 2015, you must comply with the
emission limits specified in Table 2 to this subpart beginning on June
10, 1999 or at startup, whichever is later.
(3) For each new phosphate fertilizer process line (e.g., diammonium
and/or monoammonium phosphate process line), granular triple
superphosphate process line, and granular triple superphosphate storage
building that commences construction or reconstruction after August 19,
2015, you must comply with the emission limits specified in Table 2 to
this subpart immediately upon startup.
(b) Beginning on June 10, 2002, you must not ship fresh granular
triple superphosphate from your existing granular triple superphosphate
storage building that commenced construction or reconstruction on or
before December 27, 1996. Beginning on June 10, 1999 or at startup,
whichever is later, you must not ship fresh granular triple
superphosphate from your new granular triple superphosphate storage
building that commences construction or reconstruction after December
27, 1996.
(c) Beginning on August 19, 2015, you must not introduce into any
evaporative cooling tower any liquid effluent
[[Page 35]]
from any absorber installed to control emissions from process equipment.
(d) Beginning on August 19, 2015, during periods of startup and
shutdown (as defined in Sec. 63.621), you must comply with the work
practice specified in this paragraph in lieu of the emission limits
specified in paragraph (a) of this section. During periods of startup
and shutdown, you must operate any control device(s) being used at the
affected source, monitor the operating parameters specified in Table 3
of this subpart, and comply with the operating limits specified in Table
4 of this subpart.
Sec. 63.624 [Reserved]
Sec. 63.625 Operating and monitoring requirements.
(a) For each phosphate fertilizer process line (e.g., diammonium
and/or monoammonium phosphate process line), or granular triple
superphosphate process line subject to the provisions of this subpart,
you must comply with the monitoring requirements specified in paragraphs
(a)(1) and (2) of this section.
(1) Install, calibrate, maintain, and operate a continuous
monitoring system (CMS) according to your site-specific monitoring plan
specified in Sec. 63.628(c). The CMS must have an accuracy of 5 percent over its operating range and must determine
and permanently record the mass flow of phosphorus-bearing material fed
to the process.
(2) Maintain a daily record of equivalent P2O5
feed. Calculate the equivalent P2O5 feed by
determining the total mass rate in metric ton/hour of phosphorus bearing
feed using the procedures specified in Sec. 63.626(f)(3).
(b) For each granular triple superphosphate storage building subject
to the provisions of this subpart, you must maintain an accurate record
of the mass of granular triple superphosphate in storage to permit the
determination of the amount of equivalent P2O5
stored.
(c) For each granular triple superphosphate storage building subject
to the provisions of this subpart, you must comply with the requirements
specified in paragraphs (c)(1) and (2) of this section.
(1) Maintain a daily record of total equivalent
P2O5 stored by multiplying the percentage
P2O5 content, as determined by Sec.
63.626(f)(3)(ii), by the total mass of granular triple superphosphate
stored as specified in paragraph (b) of this section.
(2) Develop for approval by the Administrator a site-specific
methodology including sufficient recordkeeping for the purposes of
demonstrating compliance with Sec. 63.622(b).
(d) If you use a control device(s) to comply with the emission
limits specified in Table 1 or 2 of this subpart, you must install a
continuous parameter monitoring system (CPMS) and comply with the
requirements specified in paragraphs (d)(1) through (4) of this section.
(1) You must monitor the operating parameter(s) applicable to the
control device that you use as specified in Table 3 to this subpart and
establish the applicable limit or range for the operating parameter
limit as specified in paragraphs (d)(1)(i) and (ii) of this section, as
applicable.
(i) Except as specified in paragraph (d)(1)(ii) of this section,
determine the value(s) as the arithmetic average of operating parameter
measurements recorded during the three test runs conducted for the most
recent performance test.
(ii) If you use an absorber to comply with the emission limits in
Table 1 or 2 to this subpart and you monitor pressure drop across the
absorber, you must establish allowable ranges using the methodology
specified in paragraphs (d)(1)(ii)(A) and (B) of this section.
(A) The allowable range for the daily averages of the pressure drop
across an absorber and of the flow rate of the absorber liquid to each
absorber in the process absorbing system, or secondary voltage for a wet
electrostatic precipitator, is 20 percent of the
baseline average value determined in paragraph (d)(1)(i) of this
section. The Administrator retains the right to reduce the 20 percent adjustment to the baseline average values of
operating ranges in those instances where performance test results
indicate that a source's level of emissions is near the value of an
applicable emissions standard. However, the
[[Page 36]]
adjustment must not be reduced to less than 10
percent under any instance.
(B) As an alternative to paragraph (d)(1)(ii)(A) of this section,
you may establish allowable ranges for the daily averages of the
pressure drop across an absorber for the purpose of assuring compliance
with this subpart using the procedures described in this paragraph. You
must establish the allowable ranges based on the baseline average values
recorded during previous performance tests or the results of performance
tests conducted specifically for the purposes of this paragraph. You
must conduct all performance tests using the methods specified in Sec.
63.626. You must certify that the control devices and processes have not
been modified since the date of the performance test from which you
obtained the data used to establish the allowable ranges. When a source
using the methodology of this paragraph is retested, you must determine
new allowable ranges of baseline average values unless the retest
indicates no change in the operating parameters outside the previously
established ranges.
(2) You must monitor, record, and demonstrate continuous compliance
using the minimum frequencies specified in Table 4 to this subpart.
(3) You must comply with the calibration and quality control
requirements that are applicable to the operating parameter(s) you
monitor as specified in Table 5 to this subpart.
(4) If you use a fabric filter system to comply with the emission
limits specified in Table 1 or 2 to this subpart, the system must meet
the requirements for fabric filters specified in paragraph (e) of this
section.
(e) Beginning August 19, 2016, if you use a fabric filter system to
comply with the emission limits specified in Table 1 or 2 to this
subpart, then the fabric filter must be equipped with a bag leak
detection system that is installed, calibrated, maintained and
continuously operated according to the requirements in paragraphs (e)(1)
through (10) of this section.
(1) Install a bag leak detection sensor(s) in a position(s) that
will be representative of the relative or absolute particulate matter
loadings for each exhaust stack, roof vent, or compartment (e.g., for a
positive-pressure fabric filter) of the fabric filter.
(2) Use a bag leak detection system certified by the manufacturer to
be capable of detecting particulate matter emissions at concentrations
of 1 milligram per actual cubic meter (0.00044 grains per actual cubic
feet) or less.
(3) Use a bag leak detection system equipped with a device to
continuously record the output signal from the system sensor.
(4) Use a bag leak detection system equipped with a system that will
trigger an alarm when an increase in relative particulate material
emissions over a preset level is detected. The alarm must be located
such that the alert is observed readily by plant operating personnel.
(5) Install a bag leak detection system in each compartment or cell
for positive-pressure fabric filter systems that do not duct all
compartments or cells to a common stack. Install a bag leak detector
downstream of the fabric filter if a negative-pressure or induced-air
filter is used. If multiple bag leak detectors are required, the
system's instrumentation and alarm may be shared among detectors.
(6) Calibration of the bag leak detection system must, at a minimum,
consist of establishing the baseline output level by adjusting the range
and the averaging period of the device and establishing the alarm set
points and the alarm delay time.
(7) After initial adjustment, you must not adjust the sensitivity or
range, averaging period, alarm set points or alarm delay time, except as
established in your site-specific monitoring plan required in Sec.
63.628(c). In no event may the sensitivity be increased more than 100
percent or decreased by more than 50 percent over a 365-day period
unless such adjustment follows a complete inspection of the fabric
filter system that demonstrates that the system is in good operating
condition.
(8) Operate and maintain each fabric filter and bag leak detection
system such that the alarm does not sound more than 5 percent of the
operating time during a 6-month period. If the alarm sounds more than 5
percent of the operating time during a 6-month
[[Page 37]]
period, it is considered an operating parameter exceedance. Calculate
the alarm time (i.e., time that the alarm sounds) as specified in
paragraphs (e)(8)(i) through (iii) of this section.
(i) If inspection of the fabric filter demonstrates that corrective
action is not required, the alarm duration is not counted in the alarm
time calculation.
(ii) If corrective action is required, each alarm time is counted as
a minimum of 1 hour.
(iii) If it takes longer than 1 hour to initiate corrective action,
each alarm time (i.e., time that the alarm sounds) is counted as the
actual amount of time taken by you to initiate corrective action.
(9) If the alarm on a bag leak detection system is triggered, you
must initiate procedures within 1 hour of an alarm to identify the cause
of the alarm and then initiate corrective action, as specified in Sec.
63.628(d)(2), no later than 48 hours after an alarm. Failure to take
these actions within the prescribed time periods is considered a
violation.
(10) Retain records of any bag leak detection system alarm,
including the date, time, duration, and the percent of the total
operating time during each 6-month period that the alarm triggers, with
a brief explanation of the cause of the alarm, the corrective action
taken, and the schedule and duration of the corrective action.

Sec. 63.626 Performance tests and compliance provisions.
(a) You must conduct an initial performance test to demonstrate
compliance with the emission limits specified in Tables 1 and 2 to this
subpart, within 180 days of the applicable compliance date specified in
Sec. 63.622.
(b) After you conduct the initial performance test specified in
paragraph (a) of this section, you must conduct a performance test once
per calendar year.
(c) For affected sources (as defined in Sec. 63.620) that have not
operated since the previous annual performance test was conducted and
more than 1 year has passed since the previous performance test, you
must conduct a performance test no later than 180 days after the re-
start of the affected source according to the applicable provisions in
Sec. 63.7(a)(2).
(d)(1) You must conduct the performance tests specified in this
section at representative (normal) conditions for the process.
Representative (normal) conditions means those conditions that:
(i) Represent the range of combined process and control measure
conditions under which the facility expects to operate (regardless of
the frequency of the conditions); and
(ii) Are likely to most challenge the emissions control measures of
the facility with regard to meeting the applicable emission standards,
but without creating an unsafe condition.
(2) Operations during startup, shutdown, and malfunction do not
constitute representative (normal) operating conditions for purposes of
conducting a performance test. You must record the process information
that is necessary to document the operating conditions during the test
and include in such record an explanation to support that such
conditions represent representative (normal) conditions. Upon request,
you must make available to the Administrator such records as may be
necessary to determine the conditions of performance tests.
(e) In conducting all performance tests, you must use as reference
methods and procedures the test methods in 40 CFR part 60, appendix A,
or other methods and procedures as specified in this section, except as
provided in Sec. 63.7(f).
(f) For each phosphate fertilizer process line (e.g., diammonium
and/or monoammonium phosphate process line), and granular triple
superphosphate process line, you must determine compliance with the
applicable total fluorides standards specified in Tables 1 and 2 to this
subpart as specified in paragraphs (f)(1) through (3) of this section.
(1) Compute the emission rate (E) of total fluorides for each run
using Equation BB-1:
[[Page 38]]

N = Number of emission points associated with the affected facility.
P = Equivalent P2O5 feed rate, metric ton/hour
(ton/hour).
K = Conversion factor, 1000 milligram/gram (453,600 milligram/pound).
(2) You must use Method 13A or 13B (40 CFR part 60, appendix A) to
determine the total fluorides concentration (Ci) and the
volumetric flow rate (Qi) of the effluent gas at each
emission point. The sampling time for each run at each emission point
must be at least 60 minutes. The sampling volume for each run at each
emission point must be at least 0.85 dscm (30 dscf). If Method 13B is
used, the fusion of the filtered material described in Section 7.3.1.2
and the distillation of suitable aliquots of containers 1 and 2,
described in section 7.3.3 and 7.3.4 in Method 13 A, may be omitted.
(3) Compute the equivalent P2O5 feed rate (P)
using Equation BB-2:

quantities of product are being cured or stored in the facility:
(i) Total granular triple superphosphate is at least 10 percent of
the building capacity, and
(ii) Fresh granular triple superphosphate is at least six percent of
the total amount of granular triple superphosphate, or
(iii) If the provision in paragraph (g)(1)(ii) of this section
exceeds production capabilities for fresh granular triple
superphosphate, the fresh granular triple superphosphate is equal to at
least 5 days maximum production.
(2) Compute the emission rate (E) of total fluorides for each run
using Equation BB-3:
[GRAPHIC] [TIFF OMITTED] TR19AU15.005
Where:
E = Emission rate of total fluorides, gram/hour/metric ton (pound/hour/

(h) If you use a CMS, you must conduct a performance evaluation, as
specified in Sec. 63.8(e), in accordance with your site-specific
monitoring plan in Sec. 63.628(c). For fabric filters, you must conduct
a performance evaluation of the bag leak detection system consistent
with the guidance provided in Office Of Air Quality Planning And
Standards (OAQPS), Fabric Filter Bag Leak Detection Guidance
(incorporated by reference, see Sec. 63.14). You must record the
sensitivity of the bag leak detection system to detecting changes in
particulate matter emissions, range, averaging period, and alarm set
points during the performance test.
Sec. 63.627 Notification, recordkeeping, and reporting requirements.
(a) You must comply with the notification requirements specified in
Sec. 63.9. During the most recent performance test, if you demonstrate
compliance with the emission limit while operating your control device
outside the previously established operating limit, you must establish a
new operating limit based on that most recent performance test and
notify the Administrator that the operating limit changed based on data
collected during the most recent performance test. When a source is
retested and the performance test results are submitted to the
Administrator pursuant to paragraph (b)(1) of this section, Sec.
63.7(g)(1), or Sec. 63.10(d)(2), you must indicate whether the
operating limit is based on the new performance test or the previously
established limit. Upon establishment of a new operating limit, you must
thereafter operate under the new operating limit. If the Administrator
determines that you did not conduct the compliance test in accordance
with the applicable requirements or that the operating limit established
during the performance test does not correspond to representative
(normal) conditions, you must conduct a new performance test and
establish a new operating limit.
(b) You must comply with the reporting and recordkeeping
requirements in Sec. 63.10 as specified in paragraphs (b)(1) through
(5) of this section.
(1) You must comply with the general recordkeeping requirements in

(2) As required by Sec. 63.10(d), you must report the results of
the initial and subsequent performance tests as part of the notification
of compliance status required in Sec. 63.9(h). You must verify in the
performance test reports that the operating limits for each process have
not changed or provide documentation of revised operating limits
established according to Sec. 63.625, as applicable. In the
notification of compliance status, you must also:
(i) Certify to the Administrator that you have not shipped fresh
granular triple superphosphate from an affected facility.
(ii) Certify to the Administrator annually that you have complied
with the evaporative cooling tower requirements specified in Sec.
63.622(c).
[[Page 41]]
(iii) Submit analyses and supporting documentation demonstrating
conformance with the Office Of Air Quality Planning And Standards
(OAQPS), Fabric Filter Bag Leak Detection Guidance (incorporated by
reference, see Sec. 63.14) and specifications for bag leak detection
systems as part of the notification of compliance status report.
(iv) If you elect to demonstrate compliance by following the
procedures in Sec. 63.625(d)(1)(ii)(B), certify to the Administrator
annually that the control devices and processes have not been modified
since the date of the performance test from which you obtained the data
used to establish the allowable ranges.
(3) As required by Sec. 63.10(e)(1), you must submit an excess
emissions report for any exceedance of an emission or operating
parameter limit if the total duration of the exceedances for the
reporting period is 1 percent of the total operating time for the
reporting period or greater. The report must contain the information
specified in Sec. 63.10 and paragraph (b)(4) of this section. When
exceedances of an emission limit or operating parameter have not
occurred, you must include such information in the report. You must
submit the report semiannually and the report must be delivered or
postmarked by the 30th day following the end of the calendar half. If
exceedances are reported, you must submit the excess emissions report
quarterly until a request to reduce reporting frequency is approved as
described in Sec. 63.10(e)(3).
(4) In the event that an affected unit fails to meet an applicable
standard, record and report the following information for each failure:
(i) The date, time and duration of the failure.
(ii) A list of the affected sources or equipment for which a failure
occurred.
(iii) An estimate of the volume of each regulated pollutant emitted
over any emission limit.
(iv) A description of the method used to estimate the emissions.
(v) A record of actions taken to minimize emissions in accordance
with Sec. 63.628(b), and any corrective actions taken to return the
affected unit to its normal or usual manner of operation.
(5) You must submit a summary report containing the information
specified in Sec. 63.10(e)(3)(vi). You must submit the summary report
semiannually and the report must be delivered or postmarked by the 30th
day following the end of the calendar half.
(c) Your records must be in a form suitable and readily available
for expeditious review. You must keep each record for 5 years following
the date of each recorded action. You must keep each record on site, or
accessible from a central location by computer or other means that
instantly provide access at the site, for at least 2 years after the
date of each recorded action. You may keep the records off site for the
remaining 3 years.
(d) In computing averages to determine compliance with this subpart,
you must exclude the monitoring data specified in paragraphs (d)(1)
through (3) of this section.
(1) Periods of non-operation of the process unit;
(2) Periods of no flow to a control device; and
(3) Any monitoring data recorded during continuous parameter
monitoring system (CPMS) breakdowns, out-of-control periods, repairs,
maintenance periods, instrument adjustments or checks to maintain
precision and accuracy, calibration checks, and zero (low-level), mid-
level (if applicable), and high-level adjustments.
(e) Within 60 days after the date of completing each performance
test (as defined in Sec. 63.2) required by this subpart, you must
submit the results of the performance tests, including any associated
fuel analyses, following the procedure specified in either paragraph
(e)(1) or (2) of this section.
(1) For data collected using test methods supported by the EPA's
Electronic Reporting Tool (ERT) as listed on the EPA's ERT Web site
(http://www.epa.gov/ttn/chief/ert/index.html), you must submit the
results of the performance test to the EPA via the Compliance and
Emissions Data Reporting Interface (CEDRI). CEDRI can be accessed
through the EPA's Central Data Exchange (CDX) (http://cdx.epa.gov/
epa_home.asp). Performance test data must be submitted in a file format
generated through the use
[[Page 42]]
of the EPA's ERT. Alternatively, you may submit performance test data in
an electronic file format consistent with the extensible markup language
(XML) schema listed on the EPA's ERT Web site once the XML schema is
available. If you claim that some of the performance test information
being submitted is confidential business information (CBI), you must
submit a complete file generated through the use of the EPA's ERT or an
alternate electronic file consistent with the XML schema listed on the
EPA's ERT Web site, including information claimed to be CBI, on a
compact disc, flash drive, or other commonly used electronic storage
media to the EPA. The electronic media must be clearly marked as CBI and
mailed to U.S. EPA/OAPQS/CORE CBI Office, Attention: Group Leader,
Measurement Policy Group, MD C404-02, 4930 Old Page Rd., Durham, NC
27703. The same ERT or alternate file with the CBI omitted must be
submitted to the EPA via the EPA's CDX as described earlier in this
paragraph.
(2) For data collected using test methods that are not supported by
the EPA's ERT as listed on the EPA's ERT Web site, you must submit the
results of the performance test to the Administrator at the appropriate
address listed in Sec. 63.13.
Sec. 63.628 General requirements and applicability of general
provisions of this part.
(a) You must comply with the general provisions in subpart A of this
part as specified in appendix A to this subpart.
(b) At all times, you must operate and maintain any affected source,
including associated air pollution control equipment and monitoring
equipment, in a manner consistent with safety and good air pollution
control practices for minimizing emissions. The general duty to minimize
emissions does not require you to make any further efforts to reduce
emissions if levels required by this standard have been achieved.
Determination by the Administrator of whether a source is operating in
compliance with operation and maintenance requirements will be based on
information available to the Administrator that may include, but is not
limited to, monitoring results, review of operation and maintenance
procedures, review of operation and maintenance records, and inspection
of the source.
(c) For each CMS used to demonstrate compliance with any applicable
emission limit, you must develop, and submit to the Administrator for
approval upon request, a site-specific monitoring plan according to the
requirements specified in paragraphs (c)(1) through (3) of this section.
You must submit the site-specific monitoring plan, if requested by the
Administrator, at least 60 days before the initial performance
evaluation of the CMS. The requirements of this paragraph also apply if
a petition is made to the Administrator for alternative monitoring
parameters under Sec. 63.8(f).
(1) You must include the information specified in paragraphs
(c)(1)(i) through (vi) of this section in the site-specific monitoring
plan.
(i) Location of the CMS sampling probe or other interface. You must
include a justification demonstrating that the sampling probe or other
interface is 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).
(ii) Performance and equipment specifications for the sample
interface, the pollutant concentration or parametric signal analyzer,
and the data collection and reduction systems.
(iii) Performance evaluation procedures and acceptance criteria
(e.g., calibrations).
(iv) Ongoing operation and maintenance procedures in accordance with
the general requirements of Sec. 63.8(c)(1)(ii), (c)(3), (c)(4)(ii),
and Table 4 to this subpart.

[[Page 43]]
(3) You must keep the site-specific monitoring plan on site for the
life of the affected source or until the affected source is no longer
subject to the provisions of this part, to be made available for
inspection, upon request, by the Administrator. If you revise the site-
specific monitoring plan, you must keep previous (i.e., superseded)
versions of the plan on site to be made available for inspection, upon
request, by the Administrator, for a period of 5 years after each
revision to the plan. You must include the program of corrective action
required under Sec. 63.8(d)(2) in the plan.
(d) For each bag leak detection system installed to comply with the
requirements specified in Sec. 63.625(e), you must include the
information specified in paragraphs (d)(1) and (2) of this section in
the site-specific monitoring plan specified in paragraph (c) of this
section.
(1) Performance evaluation procedures and acceptance criteria (e.g.,
calibrations), including how the alarm set-point will be established.
(2) A corrective action plan describing corrective actions to be
taken and the timing of those actions when the bag leak detection alarm
sounds. Corrective actions may include, but are not limited to, the
actions specified in paragraphs (d)(2)(i) through (vi) of this section.
(i) Inspecting the fabric filter for air leaks, torn or broken bags
or filter media, or any other conditions that may cause an increase in
regulated material 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 fabric filter compartment.
(v) Cleaning the bag leak detection system probe or otherwise

(vi) Shutting down the process controlled by the fabric filter.
(e) If you use blower design capacity to determine the gas flow rate
through the absorber for use in the liquid-to-gas ratio as specified in
Table 3 to this subpart, then you must include in the site-specific
monitoring plan specified in paragraph (c) of this section calculations
showing how you determined the maximum possible gas flow rate through
the absorber based on the blower's specifications (including any
adjustments you made for pressure drop).
(f) If you use a regression model to determine the gas flow rate
through the absorber for use in the liquid-to-gas ratio as specified in
Table 3 to this subpart, then you must include in the site-specific
monitoring plan specified in paragraph (c) of this section the
calculations that were used to develop the regression model, including
the calculations you use to convert amperage of the blower to brake
horsepower. You must describe any constants included in the equations
(e.g., efficiency, power factor), and describe how these constants were
determined. If you want to change a constant in your calculation, then
you must conduct a regression model verification to confirm the new
value of the constant. In addition, the site-specific monitoring plan
must be updated annually to reflect the data used in the annual
regression model verification that is described in Table 3 to this
subpart.

\a\ To monitor an operating parameter that is not specified in this table (including process-specific techniques
not specified in this table to determine gas flow rate through an absorber), you must request, on a site-
specific basis, an alternative monitoring method under the provisions of Sec. 63.8(f).
\b\ For new sources that commence construction or reconstruction after August 19, 2015, the compliance date is
immediately upon startup. For existing sources, and new sources that commence construction or reconstruction
after December 27, 1996, and on or before August 19, 2015, if your absorber is designed and operated with
pressure drops of 5 inches of water column or less, then the compliance date is August 19, 2018. In the
interim, for existing sources, and new sources that commence construction or reconstruction after December 27,
1996, and on or before August 19, 2015, with an absorber designed and operated with pressure drops of 5 inches
of water column or less, you must comply with one of the following: (i) The monitoring requirements in this
Table 3 for absorbers designed and operated with pressure drops of 5 inches of water column or less; (ii) the
applicable monitoring provisions included in a permit issued under 40 CFR part 70 to assure compliance with
subpart BB; (iii) the applicable monitoring provisions of an Alternative Monitoring Plan approved pursuant to
Sec. 63.8(f); or (iv) install CPMS for pressure at the gas stream inlet and outlet of the absorber, and
monitor pressure drop through the absorber.
\c\ If you select this option, then you must comply with Sec. 63.628(e). The option to use blower design
capacity is intended to establish the maximum possible gas flow through the absorber; and is available
regardless of the location of the blower (influent or effluent), as long as the gas flow rate through the
absorber can be established. Establish the minimum liquid-to-gas ratio operating limit by dividing the minimum
liquid flow rate to the absorber (determined during a performance test) by the maximum possible gas flow rate
through the absorber (determined using blower design capacity).
\d\ If you select this option, then you must comply with Sec. 63.628(f). The regression model must be
developed using direct measurements of gas flow rate, and design fan curves that correlate gas flow rate to
static pressure (i.e., fan suction pressure) and brake horsepower of the blower. You must conduct an annual
regression model verification using direct measurements of gas flow rate to ensure the correlation remains
accurate. Direct measurements of gas flow rate used to develop or verify regression models may be collected
during, or separately from, the annual performance testing that is required in Sec. 63.626(b).

paragraphs (e)(1) and (e)(2) of this section to determine whether a
storage vessel is part of a source to which this subpart applies. The
owner or operator of a storage vessel constructed after August 18, 1994,
shall follow the procedures specified in paragraphs (e)(1), (e)(2)(i),
and (e)(2)(ii) of this section to determine whether a storage vessel is
part of a source to which this subpart applies.
(1) Where a storage vessel is used exclusively by a process unit,
the storage vessel shall be considered part of that process unit.
(i) If the process unit is a petroleum refining process unit subject
to this subpart, then the storage vessel is part of the affected source
to which this subpart applies.
(ii) If the process unit is not subject to this subpart, then the
storage vessel is not part of the affected source to which this subpart
applies.
(2) If a storage vessel is not dedicated to a single process unit,
then the applicability of this subpart shall be determined according to
the provisions in paragraphs (e)(2)(i) through (e)(2)(iii) of this
section.
(i) If a storage vessel is shared among process units and one of the
process units has the predominant use, as determined by paragraphs
(e)(2)(i)(A) and (e)(2)(i)(B) of this section, then the storage vessel
is part of that process unit.
(A) If the greatest input on a volume basis into the storage vessel
is from a process unit that is located on the same plant site, then that
process unit has the predominant use.
[[Page 51]]
(B) If the greatest input on a volume basis into the storage vessel
is provided from a process unit that is not located on the same plant
site, then the predominant use shall be the process unit that receives
the greatest amount of material on a volume basis from the storage
vessel at the same plant site.
(ii) If a storage vessel is shared among process units so that there
is no single predominant use, and at least one of those process units is
a petroleum refining process unit subject to this subpart, the storage
vessel shall be considered to be part of the petroleum refining process
unit that is subject to this subpart. If more than one petroleum
refining process unit is subject to this subpart, the owner or operator
may assign the storage vessel to any of the petroleum refining process
units subject to this subpart.
(iii) If the predominant use of a storage vessel varies from year to
year, then the applicability of this subpart shall be determined based
on the utilization of that storage vessel during the year preceding
August 18, 1995. This determination shall be reported as specified in
Sec. 63.655(h)(6)(ii).
(f) The owner or operator of a distillation unit constructed on or
before August 18, 1994, shall follow the procedures specified in
paragraphs (f)(1) through (f)(4) of this section to determine whether a
miscellaneous process vent from a distillation unit is part of a source
to which this subpart applies. The owner or operator of a distillation
unit constructed after August 18, 1994, shall follow the procedures
specified in paragraphs (f)(1) through (f)(5) of this section to
determine whether a miscellaneous process vent from a distillation unit
is part of a source to which this subpart applies.
(1) If the greatest input to the distillation unit is from a process
unit located on the same plant site, then the distillation unit shall be
assigned to that process unit.
(2) If the greatest input to the distillation unit is provided from
a process unit that is not located on the same plant site, then the
distillation unit shall be assigned to the process unit located at the
same plant site that receives the greatest amount of material from the
distillation unit.
(3) If a distillation unit is shared among process units so that
there is no single predominant use, as described in paragraphs (f)(1)
and (f)(2) of this section, and at least one of those process units is a
petroleum refining process unit subject to this subpart, the
distillation unit shall be assigned to the petroleum refining process
unit that is subject to this subpart. If more than one petroleum
refining process unit is subject to this subpart, the owner or operator
may assign the distillation unit to any of the petroleum refining
process units subject to this rule.
(4) If the process unit to which the distillation unit is assigned
is a petroleum refining process unit subject to this subpart and the
vent stream contains greater than 20 parts per million by volume total
organic hazardous air pollutants, then the vent from the distillation
unit is considered a miscellaneous process vent (as defined in Sec.
63.641 of this subpart) and is part of the source to which this subpart
applies.
(5) If the predominant use of a distillation unit varies from year
to year, then the applicability of this subpart shall be determined
based on the utilization of that distillation unit during the year
preceding August 18, 1995. This determination shall be reported as
specified in Sec. 63.655(h)(6)(iii).

Sec. 63.641 Definitions.
All terms used in this subpart shall have the meaning given them in
the Clean Air Act, subpart A of this part, and in this section. If the
same term is defined in subpart A and in this section, it shall have the
meaning given in this section for purposes of this subpart.
Affected source means the collection of emission points to which
this subpart applies as determined by the criteria in Sec. 63.640.
Aliphatic means open-chained structure consisting of paraffin,
olefin and acetylene hydrocarbons and derivatives.

G of this part;
(2) From standard reference texts; or
(3) By any other method approved by the Administrator.
Assist air means all air that intentionally is introduced prior to
or at a flare tip through nozzles or other hardware conveyance for the
purposes including, but not limited to, protecting the design of the
flare tip, promoting turbulence for mixing or inducing air into the
flame. Assist air includes premix assist air and perimeter assist air.
Assist air does not include the surrounding ambient air.
Assist steam means all steam that intentionally is introduced prior
to or at a flare tip through nozzles or other hardware conveyance for
the purposes including, but not limited to, protecting the design of the
flare tip, promoting turbulence for mixing or inducing air into the
flame. Assist steam includes, but is not necessarily limited to, center
steam, lower steam and upper steam.
Boiler means any enclosed combustion device that extracts useful
energy in the form of steam and is not an incinerator.
By compound means by individual stream components, not by carbon
equivalents.
Car-seal means a seal that is placed on a device that is used to
change the position of a valve (e.g., from opened to closed) in such a
way that the position
[[Page 59]]
of the valve cannot be changed without breaking the seal.
Center steam means the portion of assist steam introduced into the
stack of a flare to reduce burnback.
Closed blowdown system means a system used for depressuring process
vessels that is not open to the atmosphere and is configured of piping,
ductwork, connections, accumulators/knockout drums, and, if necessary,
flow inducing devices that transport gas or vapor from a process vessel
to a control device or back into the process.
Closed vent system means a system that is not open to the atmosphere
and is configured of piping, ductwork, connections, and, if necessary,
flow inducing devices that transport gas or vapor from an emission point
to a control device or back into the process. If gas or vapor from
regulated equipment is routed to a process (e.g., to a petroleum
refinery fuel gas system), the process shall not be considered a closed
vent system and is not subject to closed vent system standards.
Combustion device means an individual unit of equipment such as a
flare, incinerator, process heater, or boiler used for the combustion of
organic hazardous air pollutant vapors.
Combustion zone means the area of the flare flame where the
combustion zone gas combines for combustion.
Combustion zone gas means all gases and vapors found just after a
flare tip. This gas includes all flare vent gas, total steam, and premix
air.
Connector means flanged, screwed, or other joined fittings used to
connect two pipe lines or a pipe line and a piece of equipment. A common
connector is a flange. Joined fittings welded completely around the

incinerators, flares, boilers, and process heaters. For miscellaneous
process vents (as defined in this section), recovery devices (as defined
in this section) are not considered control devices.
Cooling tower means a heat removal device used to remove the heat
absorbed in circulating cooling water systems by transferring the heat
to the atmosphere using natural or mechanical draft.
Cooling tower return line means the main water trunk lines at the
inlet to the cooling tower before exposure to the atmosphere.
Decoking operations means the sequence of steps conducted at the end
of the delayed coking unit's cooling cycle to open the coke drum to the
atmosphere in order to remove coke from the coke drum. Decoking
operations begin at the end of the cooling cycle when steam released
from the coke drum is no longer discharged via the unit's blowdown
system but instead is vented directly to the atmosphere. Decoking
operations include atmospheric depressuring (venting), deheading,
draining, and decoking (coke cutting).
Delayed coking unit means a refinery process unit in which high
molecular weight petroleum derivatives are thermally cracked and
petroleum coke is produced in a series of closed, batch system reactors.
A delayed coking unit includes, but is not limited to, all of the coke
drums associated with a single fractionator; the fractionator, including
the bottoms receiver and the overhead condenser; the coke drum cutting
water and quench system, including the jet pump and coker quench water
tank; and the coke drum blowdown recovery compressor system.
Delayed coker vent means a miscellaneous process vent that contains
uncondensed vapors from the delayed coking unit's blowdown system.
Venting from the delayed coker vent is typically intermittent in nature,
and occurs primarily during the cooling cycle of a delayed coking unit
coke drum
[[Page 60]]
when vapor from the coke drums cannot be sent to the fractionator column
for product recovery. The emissions from the decoking operations, which
include direct atmospheric venting, deheading, draining, or decoking
(coke cutting), are not considered to be delayed coker vents.
Distillate receiver means overhead receivers, overhead accumulators,
reflux drums, and condenser(s) including ejector-condenser(s) associated
with a distillation unit.
Distillation unit means a device or vessel in which one or more feed
streams are separated into two or more exit streams, each exit stream
having component concentrations different from those in the feed
stream(s). The separation is achieved by the redistribution of the
components between the liquid and the vapor phases by vaporization and
condensation as they approach equilibrium within the distillation unit.
Distillation unit includes the distillate receiver, reboiler, and any
associated vacuum pump or steam jet.
Emission point means an individual miscellaneous process vent,
storage vessel, wastewater stream, equipment leak, decoking operation or
heat exchange system associated with a petroleum refining process unit;
an individual storage vessel or equipment leak associated with a bulk
gasoline terminal or pipeline breakout station classified under Standard
Industrial Classification code 2911; a gasoline loading rack classified
under Standard Industrial Classification code 2911; or a marine tank
vessel loading operation located at a petroleum refinery.
Equipment leak means emissions of organic hazardous air pollutants
from a pump, compressor, pressure relief device, sampling connection
system, open-ended valve or line, valve, or instrumentation system ``in
organic hazardous air pollutant service'' as defined in this section.
Vents from wastewater collection and conveyance systems (including, but
not limited to wastewater drains, sewer vents, and sump drains), tank
mixers, and sample valves on storage tanks are not equipment leaks.
Flame zone means the portion of a combustion chamber of a boiler or
process heater occupied by the flame envelope created by the primary
fuel.
Flare means a combustion device lacking an enclosed combustion
chamber that uses an uncontrolled volume of ambient air to burn gases.
For the purposes of this rule, the definition of flare includes, but is
not necessarily limited to, air-assisted flares, steam-assisted flares
and non-assisted flares.
Flare purge gas means gas introduced between a flare header's water
seal and the flare tip to prevent oxygen infiltration (backflow) into
the flare tip or for other safety reasons. For a flare with no water
seal, the function of flare purge gas is performed by flare sweep gas
and, therefore, by definition, such a flare has no flare purge gas.
Flare supplemental gas means all gas introduced to the flare to
improve the heat content of combustion zone gas. Flare supplemental gas
does not include assist air or assist steam.
Flare sweep gas means, for a flare with a flare gas recovery system,
the gas intentionally introduced into the flare header system to
maintain a constant flow of gas through the flare header in order to
prevent oxygen buildup in the flare header; flare sweep gas in these
flares is introduced prior to and recovered by the flare gas recovery
system. For a flare without a flare gas recovery system, flare sweep gas
means the gas intentionally introduced into the flare header system to
maintain a constant flow of gas through the flare header and out the
flare tip in order to prevent oxygen buildup in the flare header and to
prevent oxygen infiltration (backflow) into the flare tip.
Flare vent gas means all gas found just prior to the flare tip. This
gas includes all flare waste gas (i.e., gas from facility operations
that is directed to a flare for the purpose of disposing of the gas),
that portion of flare sweep gas that is not recovered, flare purge gas
and flare supplemental gas, but does not include pilot gas, total steam

provisions in Sec. Sec. 63.643 through 63.645, 63.646 or 63.660,
63.647, 63.650, and 63.651, as specified in Sec. 63.640(h).
(1) The owner or operator using this compliance approach shall also
comply with the requirements of Sec. Sec. 63.648 and/or 63.649, 63.654,
63.655, 63.657, 63.658, 63.670 and 63.671, as applicable.
(2) The owner or operator using this compliance approach is not
required to calculate the annual emission rate specified in paragraph
(g) of this section.
(l) The owner or operator of an existing source may elect to control
some of the emission points within the source to different levels than
specified under Sec. Sec. 63.643 through 63.645, 63.646 or 63.660,
63.647, 63.650, and 63.651, as applicable according to Sec. 63.640(h),
by using an emissions averaging compliance approach as long as the
overall emissions for the source do not exceed the emission level
specified in paragraph (g) of this section. The owner or operator using
emissions averaging shall meet the requirements in paragraphs (l)(1) and
(2) of this section.
(1) Calculate emission debits and credits for those emission points
involved in the emissions average according to the procedures specified
in Sec. 63.652; and
(2) Comply with the requirements of Sec. Sec. 63.648 and/or 63.649,
63.654, 63.652, 63.653, 63.655, 63.657, 63.658, 63.670 and 63.671, as
applicable.
[[Page 69]]
(m) A State may restrict the owner or operator of an existing source
to using only the procedures in paragraph (k) of this section to comply
with the emission standard in paragraph (g) of this section. Such a
restriction would preclude the source from using an emissions averaging
compliance approach.
(n) At all times, the owner or operator must operate and maintain
any affected source, including associated air pollution control
equipment and monitoring equipment, in a manner consistent with safety
and good air pollution control practices for minimizing emissions. The
general duty to minimize emissions does not require the owner operator
to make any further efforts to reduce emissions if levels required by
the applicable standard have been achieved. Determination of whether a
source is operating in compliance with operation and maintenance
requirements will be based on information available to the Administrator
which may include, but is not limited to, monitoring results, review of
operation and maintenance procedures, review of operation and
maintenance records, and inspection of the source.

Sec. 63.643 Miscellaneous process vent provisions.
(a) The owner or operator of a Group 1 miscellaneous process vent as
defined in Sec. 63.641 shall comply with the requirements of either
paragraph (a)(1) or (2) of this section or, if applicable, paragraph (c)
of this section. The owner or operator of a miscellaneous process vent
that meets the conditions in paragraph (c) of this section is only
required to comply with the requirements of paragraph (c) of this
section and Sec. 63.655(g)(13) and (i)(12) for that vent.
(1) Reduce emissions of organic HAP's using a flare. On and after
January 30, 2019, the flare shall meet the requirements of Sec. 63.670.
Prior to January 30, 2019, the flare shall meet the requirements of
Sec. 63.11(b) of subpart A or the requirements of Sec. 63.670.
(2) Reduce emissions of organic HAP's, using a control device, by 98
weight-percent or to a concentration of 20 parts per million by volume,
on a dry basis, corrected to 3 percent oxygen, whichever is less
stringent. Compliance can be determined by measuring either organic
HAP's or TOC's using the procedures in Sec. 63.645.
(b) If a boiler or process heater is used to comply with the
percentage of reduction requirement or concentration limit specified in
paragraph (a)(2) of this section, then the vent stream shall be
introduced into the flame zone of such a device, or in a location such
that the required percent reduction or concentration is achieved.
Testing and monitoring is required only as specified in Sec. Sec.
63.644(a) and 63.645 of this subpart.
(c) An owner or operator may designate a process vent as a
maintenance vent if the vent is only used as a result of startup,
shutdown, maintenance, or inspection of equipment where equipment is
emptied, depressurized, degassed or placed into service. The owner or
operator does not need to designate a maintenance vent as a Group 1 or
Group 2 miscellaneous process vent nor identify maintenance vents in a
Notification of Compliance Status report. The owner or operator must
comply with the applicable requirements in paragraphs (c)(1) through (3)
of this section for each maintenance vent according to the compliance
dates specified in table 11 of this subpart, unless an extension is
requested in accordance with the provisions in Sec. 63.6(i).
(1) Prior to venting to the atmosphere, process liquids are removed
from the equipment as much as practical and the equipment is depressured
to a control device meeting requirements in paragraphs (a)(1) or (2) of
this section, a fuel gas system, or back to the process until one of the
following conditions, as applicable, is met.
(i) The vapor in the equipment served by the maintenance vent has a
lower explosive limit (LEL) of less than 10 percent.
(ii) If there is no ability to measure the LEL of the vapor in the
equipment based on the design of the equipment, the pressure in the
equipment served by the maintenance vent is reduced to
[[Page 70]]
5 pounds per square inch gauge (psig) or less. Upon opening the
maintenance vent, active purging of the equipment cannot be used until
the LEL of the vapors in the maintenance vent (or inside the equipment
if the maintenance is a hatch or similar type of opening) is less than
10 percent.
(iii) The equipment served by the maintenance vent contains less
than 72 pounds of total volatile organic compounds (VOC).
(iv) If the maintenance vent is associated with equipment containing
pyrophoric catalyst (e.g., hydrotreaters and hydrocrackers) and a pure
hydrogen supply is not available at the equipment at the time of the
startup, shutdown, maintenance, or inspection activity, the LEL of the
vapor in the equipment must be less than 20 percent, except for one
event per year not to exceed 35 percent.
(v) If, after applying best practices to isolate and purge equipment
served by a maintenance vent, none of the applicable criterion in
paragraphs (c)(1)(i) through (iv) can be met prior to installing or
removing a blind flange or similar equipment blind, the pressure in the
equipment served by the maintenance vent is reduced to 2 psig or less,
Active purging of the equipment may be used provided the equipment
pressure at the location where purge gas is introduced remains at 2 psig
or less.
(2) Except for maintenance vents complying with the alternative in
paragraph (c)(1)(iii) of this section, the owner or operator must
determine the LEL or, if applicable, equipment pressure using process
instrumentation or portable measurement devices and follow procedures
for calibration and maintenance according to manufacturer's
specifications.
(3) For maintenance vents complying with the alternative in
paragraph (c)(1)(iii) of this section, the owner or operator shall
determine mass of VOC in the equipment served by the maintenance vent
based on the equipment size and contents after considering any contents
drained or purged from the equipment. Equipment size may be determined
from equipment design specifications. Equipment contents may be
determined using process knowledge.
(d) After February 1, 2016 and prior to the date of compliance with
the maintenance vent provisions in paragraph (c) of this section, the
owner or operator must comply with the requirements in Sec. 63.642(n)
for each maintenance venting event and maintain records necessary to
demonstrate compliance with the requirements in Sec. 63.642(n)
including, if appropriate, records of existing standard site procedures
used to deinventory equipment for safety purposes.

Sec. 63.644 Monitoring provisions for miscellaneous process vents.
(a) Except as provided in paragraph (b) of this section, each owner
or operator of a Group 1 miscellaneous process vent that uses a
combustion device to comply with the requirements in Sec. 63.643(a)
shall install the monitoring equipment specified in paragraph (a)(1),
(2), (3), or (4) of this section, depending on the type of combustion
device used. All monitoring equipment shall be installed, calibrated,
maintained, and operated according to manufacturer's specifications or
other written procedures that provide adequate assurance that the
equipment will monitor accurately and, except for CPMS installed for
pilot flame monitoring, must meet the applicable minimum accuracy,
calibration and quality control requirements specified in table 13 of
this subpart.
(1) Where an incinerator is used, a temperature monitoring device
equipped with a continuous recorder is required.
(i) Where an incinerator other than a catalytic incinerator is used,
a temperature monitoring device shall be installed in the firebox or in
the ductwork immediately downstream of the firebox in a position before
any substantial heat exchange occurs.
(ii) Where a catalytic incinerator is used, temperature monitoring
devices shall be installed in the gas stream immediately before and
after the catalyst bed.
(2) Where a flare is used prior to January 30, 2019, a device
(including but
[[Page 71]]
not limited to a thermocouple, an ultraviolet beam sensor, or an
infrared sensor) capable of continuously detecting the presence of a
pilot flame is required, or the requirements of Sec. 63.670 shall be
met. Where a flare is used on and after January 30, 2019, the
requirements of Sec. 63.670 shall be met.
(3) Any boiler or process heater with a design heat input capacity
greater than or equal to 44 megawatt or any boiler or process heater in
which all vent streams are introduced into the flame zone is exempt from
monitoring.
(4) Any boiler or process heater less than 44 megawatts design heat
capacity where the vent stream is not introduced into the flame zone is
required to use a temperature monitoring device in the firebox equipped
with a continuous recorder.
(b) An owner or operator of a Group 1 miscellaneous process vent may
request approval to monitor parameters other than those listed in
paragraph (a) of this section. The request shall be submitted according
to the procedures specified in Sec. 63.655(h). Approval shall be
requested if the owner or operator:
(1) Uses a control device other than an incinerator, boiler, process
heater, or flare; or
(2) Uses one of the control devices listed in paragraph (a) of this
section, but seeks to monitor a parameter other than those specified in
paragraph (a) of this section.
(c) The owner or operator of a Group 1 miscellaneous process vent
using a vent system that contains bypass lines that could divert a vent
stream away from the control device used to comply with paragraph (a) of
this section either directly to the atmosphere or to a control device
that does not comply with the requirements in Sec. 63.643(a) shall
comply with either paragraph (c)(1), (2), or (3) of this section. Use of
the bypass at any time to divert a Group 1 miscellaneous process vent
stream to the atmosphere or to a control device that does not comply
with the requirements in Sec. 63.643(a) is an emissions standards
violation. Equipment such as low leg drains and equipment subject to
Sec. 63.648 are not subject to this paragraph (c).
(1) Install, calibrate and maintain a flow indicator that determines
whether a vent stream flow is present at least once every hour. A manual
block valve equipped with a valve position indicator may be used in lieu
of a flow indicator, as long as the valve position indicator is
monitored continuously. Records shall be generated as specified in Sec.
63.655(h) and (i). The flow indicator shall be installed at the entrance
to any bypass line that could divert the vent stream away from the
control device to the atmosphere; or
(2) Secure the bypass line valve in the non-diverting position with
a car-seal or a lock-and-key type configuration. A visual inspection of
the seal or closure mechanism shall be performed at least once every
month to ensure that the valve is maintained in the non-diverting
position and that the vent stream is not diverted through the bypass
line; or
(3) Use a cap, blind flange, plug, or a second valve for an open-
ended valve or line following the requirements specified in Sec.
60.482-6(a)(2), (b) and (c).
(d) The owner or operator shall establish a range that ensures
compliance with the emissions standard for each parameter monitored
under paragraphs (a) and (b) of this section. In order to establish the
range, the information required in Sec. 63.655(f)(3) shall be submitted
in the Notification of Compliance Status report.
(e) Each owner or operator of a control device subject to the
monitoring provisions of this section shall operate the control device
in a manner consistent with the minimum and/or maximum operating
parameter value or procedure required to be monitored under paragraphs
(a) and (b) of this section. Operation of the control device in a manner
that constitutes a period of excess emissions, as defined in Sec.
63.655(g)(6), or failure to perform procedures required by this section
shall constitute a violation of the applicable emission standard of this
subpart.

subpart) (if any recovery devices are present) but prior to the inlet of
any control device (as defined in Sec. 63.641 of this subpart) that is
present, prior to any dilution of the process vent stream, and prior to
release to the atmosphere.
(1) Methods 1 or 1A of 40 CFR part 60, appendix A-1, as appropriate,
shall be used for selection of the sampling site. For vents smaller than
0.10 meter in diameter, sample at the center of the vent.
(2) No traverse site selection method is needed for vents smaller
than 0.10 meter in diameter.
(f) Except as provided in paragraph (g) of this section, an owner or
operator seeking to demonstrate that a process vent TOC mass flow rate
is less than 33 kilograms per day for an existing source or less than
6.8 kilograms per day for a new source in accordance with the Group 2
process vent definition of this subpart shall determine the TOC mass
flow rate by the following procedures:
(1) The sampling site shall be selected as specified in paragraph
(e) of this section.
(2) The gas volumetric flow rate shall be determined using Methods
2, 2A, 2C, 2D, or 2F of 40 CFR part 60, appendix A-1 or Method 2G of 40

per gram) (minute per day), where the standard temperature
(standard cubic meter) is at 20 [deg]C.
Cj = Concentration on a dry basis of organic compound j in
parts per million as measured by Method 18 of 40 CFR part 60,
appendix A, as indicated in paragraph (f)(3) of this section.
Cj includes all organic compounds measured minus
methane and ethane.
Mj = Molecular weight of organic compound j, gram per gram-
mole.
Qs = Vent stream flow rate, dry standard cubic meters per
minute, at a temperature of 20 [deg]C.
(5) If Method 25A is used, the emission rate of TOC
(ETOC) shall be calculated using the following equation:

sample, kilograms per day.
K2 = Constant, 5.986 x 10-5 (parts per million)
-1 (gram-mole per standard cubic meter) (kilogram
per gram)(minute per day), where the standard temperature
(standard cubic meter) is at 20 [deg]C.
CTOC = Concentration of TOC on a dry basis in parts per
million volume as measured by Method 25A of 40 CFR part 60,
appendix A, as indicated in paragraph (f)(3) of this section.
M = Molecular weight of organic compound used to express units of
CTOC, gram per gram-mole.
Qs = Vent stream flow rate, dry standard cubic meters per
minute, at a temperature of 20 [deg]C.
(g) Engineering assessment may be used to determine the TOC emission
rate for the representative operating condition expected to yield the
highest daily emission rate.
(1) Engineering assessment includes, but is not limited to, the
following:
(i) Previous test results provided the tests are representative of
current operating practices at the process unit.
(ii) Bench-scale or pilot-scale test data representative of the
process under representative operating conditions.
(iii) TOC emission rate specified or implied within a permit limit
applicable to the process vent.
(iv) Design analysis based on accepted chemical engineering
principles, measurable process parameters, or physical or chemical laws
or properties. Examples of analytical methods include, but are not
limited to:
(A) Use of material balances based on process stoichiometry to
estimate maximum TOC concentrations;
(B) Estimation of maximum flow rate based on physical equipment
design such as pump or blower capacities; and
(C) Estimation of TOC concentrations based on saturation conditions.
(v) All data, assumptions, and procedures used in the engineering
assessment shall be documented.
(h) The owner or operator of a Group 2 process vent shall

in paragraph (c) of this section (such as every 6 weeks instead of
monthly or quarterly) are minor and do not significantly affect the
quality of the data. An example of a minor departure is monitoring at a
slightly different frequency (such as every 6 weeks instead of monthly
or quarterly). Failure to use a calibrated instrument is not considered
a minor departure.
(c) In lieu of complying with the existing source provisions of
paragraph (a) in this section, an owner or operator may elect to comply
with the requirements of Sec. Sec. 63.161 through 63.169, 63.171,
63.172, 63.175, 63.176, 63.177, 63.179, and 63.180 except as provided in

owner or operator must comply with the requirements specified in
paragraphs (j)(1) and (2) of this section for pressure relief devices,
such as relief valves or rupture disks, in organic HAP gas or vapor
service instead of the pressure relief device requirements of Sec.
60.482-4 or Sec. 63.165, as applicable. Except as specified in
paragraphs (j)(4) and (5) of this section, the owner or operator must
also comply with the requirements specified in paragraph (j)(3) of this
section for all pressure relief devices in organic HAP service.
(1) Operating requirements. Except during a pressure release,
operate each pressure relief device in organic HAP gas or vapor service
with an instrument reading of less than 500 ppm above background as
detected by Method 21 of 40 CFR part 60, appendix A-7.
(2) Pressure release requirements. For pressure relief devices in

the applicable requirements in paragraphs (j)(2)(i) through (iii) of
this section following a pressure release.
(i) If the pressure relief device does not consist of or include a
rupture disk, conduct instrument monitoring, as specified in Sec.
60.485(b) or Sec. 63.180(c), as applicable, no later than 5 calendar
days after the pressure relief device returns to organic HAP gas or
vapor service following a pressure release to verify that the pressure
relief device is operating with an instrument reading of less than 500
ppm.
(ii) If the pressure relief device includes a rupture disk, either
comply with the requirements in paragraph (j)(2)(i) of this section (not
replacing the rupture disk) or install a replacement disk as soon as
practicable after a pressure release, but no later than 5 calendar days
after the pressure release. The owner or operator must conduct
instrument monitoring, as specified in Sec. 60.485(b) or Sec.
63.180(c), as applicable, no later than 5 calendar days after the
pressure relief device returns to organic HAP gas or vapor service
following a pressure release to verify that the pressure relief device
is operating with an instrument reading of less than 500 ppm.
(iii) If the pressure relief device consists only of a rupture disk,
install a replacement disk as soon as practicable after a pressure
release, but no later than 5 calendar days after the pressure release.
The owner or operator may not initiate startup of the equipment served
by the rupture disk until the rupture disc is replaced. The owner or
operator must conduct instrument monitoring, as specified in Sec.
60.485(b) or Sec. 63.180(c), as applicable, no later than 5 calendar
days after the pressure relief device returns to organic HAP gas or
vapor service following a pressure release to verify that the pressure
relief device is operating with an instrument reading of less than 500
ppm.
(3) Pressure release management. Except as specified in paragraphs
(j)(4) and (5) of this section, the owner or operator shall comply with
the requirements specified in paragraphs (j)(3)(i) through (v) of this
section for all pressure relief devices in organic HAP service no later
than January 30, 2019.
(i) The owner or operator must equip each affected pressure relief
device with a device(s) or use a monitoring system that is capable of:
(A) Identifying the pressure release;
(B) Recording the time and duration of each pressure release; and
(C) Notifying operators immediately that a pressure release is
occurring. The device or monitoring system may be either specific to the
pressure relief device itself or may be associated with the process
system or piping, sufficient to indicate a pressure release to the
atmosphere. Examples of these types of devices and systems include, but
are not limited to, a rupture disk indicator, magnetic sensor, motion
detector on the pressure relief valve stem, flow monitor, or pressure
monitor.
[[Page 79]]
(ii) The owner or operator must apply at least three redundant
prevention measures to each affected pressure relief device and document
these measures. Examples of prevention measures include:
(A) Flow, temperature, liquid level and pressure indicators with
deadman switches, monitors, or automatic actuators. Independent, non-
duplicative systems within this category count as separate redundant
prevention measures.
(B) Documented routine inspection and maintenance programs and/or
operator training (maintenance programs and operator training may count
as only one redundant prevention measure).
(C) Inherently safer designs or safety instrumentation systems.
(D) Deluge systems.
(E) Staged relief system where initial pressure relief device (with
lower set release pressure) discharges to a flare or other closed vent
system and control device.
(iii) If any affected pressure relief device releases to atmosphere
as a result of a pressure release event, the owner or operator must
perform root cause analysis and corrective action analysis according to
the requirement in paragraph (j)(6) of this section and implement
corrective actions according to the requirements in paragraph (j)(7) of
this section. The owner or operator must also calculate the quantity of
organic HAP released during each pressure release event and report this
quantity as required in Sec. 63.655(g)(10)(iii). Calculations may be
based on data from the pressure relief device monitoring alone or in
combination with process parameter monitoring data and process
knowledge.
(iv) The owner or operator shall determine the total number of
release events occurred during the calendar year for each affected
pressure relief device separately. The owner or operator shall also
determine the total number of release events for each pressure relief
device for which the root cause analysis concluded that the root cause
was a force majeure event, as defined in this subpart.
(v) Except for pressure relief devices described in paragraphs
(j)(4) and (5) of this section, the following release events from an
affected pressure relief device are a violation of the pressure release
management work practice standards:
(A) Any release event for which the root cause of the event was
determined to be operator error or poor maintenance.
(B) A second release event not including force majeure events from a
single pressure relief device in a 3 calendar year period for the same
root cause for the same equipment.
(C) A third release event not including force majeure events from a
single pressure relief device in a 3 calendar year period for any
reason.
(4) Pressure relief devices routed to a control device. (i) If all
releases and potential leaks from a pressure relief device are routed
through a closed vent system to a control device, back into the process
or to the fuel gas system, the owner or operator is not required to
comply with paragraph (j)(1), (2), or (3) (if applicable) of this
section.
(ii) If a pilot-operated pressure relief device is used and the
primary release valve is routed through a closed vent system to a
control device, back into the process or to the fuel gas system, the
owner or operator is required to comply only with paragraphs (j)(1) and
(2) of this section for the pilot discharge vent and is not required to
comply with paragraph (j)(3) of this section for the pilot-operated
pressure relief device.
(iii) If a balanced bellows pressure relief device is used and the
primary release valve is routed through a closed vent system to a
control device, back into the process or to the fuel gas system, the
owner or operator is required to comply only with paragraphs (j)(1) and
(2) of this section for the bonnet vent and is not required to comply
with paragraph (j)(3) of this section for the balanced bellows pressure
relief device.
(iv) Both the closed vent system and control device (if applicable)
referenced in paragraphs (j)(4)(i) through (iii) of this section must
meet the requirements of Sec. 63.644. When complying with this
paragraph (j)(4), all references to ``Group 1 miscellaneous process
vent''
[[Page 80]]
in Sec. 63.644 mean ``pressure relief device.''
(v) If a pressure relief device complying with this paragraph (j)(4)
is routed to the fuel gas system, then on and after January 30, 2019,
any flares receiving gas from that fuel gas system must be in compliance
with Sec. 63.670.
(5) Pressure relief devices exempted from pressure release
management requirements. The following types of pressure relief devices
are not subject to the pressure release management requirements in
paragraph (j)(3) of this section.
(i) Pressure relief devices in heavy liquid service, as defined in
Sec. 63.641.
(ii) Pressure relief devices that only release material that is
liquid at standard conditions (1 atmosphere and 68 degrees Fahrenheit)
and that are hard-piped to a controlled drain system (i.e., a drain
system meeting the requirements for Group 1 wastewater streams in Sec.
63.647(a)) or piped back to the process or pipeline.
(iii) Thermal expansion relief valves.
(iv) Pressure relief devices designed with a set relief pressure of
less than 2.5 psig.
(v) Pressure relief devices that do not have the potential to emit
72 lbs/day or more of VOC based on the valve diameter, the set release
pressure, and the equipment contents.
(vi) Pressure relief devices on mobile equipment.
(6) Root cause analysis and corrective action analysis. A root cause
analysis and corrective action analysis must be completed as soon as
possible, but no later than 45 days after a release event. Special
circumstances affecting the number of root cause analyses and/or
corrective action analyses are provided in paragraphs (j)(6)(i) through
(iv) of this section.
(i) You may conduct a single root cause analysis and corrective
action analysis for a single emergency event that causes two or more
pressure relief devices installed on the same equipment to release.
(ii) You may conduct a single root cause analysis and corrective
action analysis for a single emergency event that causes two or more
pressure relief devices to release, regardless of the equipment served,
if the root cause is reasonably expected to be a force majeure event, as
defined in this subpart.
(iii) Except as provided in paragraphs (j)(6)(i) and (ii) of this
section, if more than one pressure relief device has a release during
the same time period, an initial root cause analysis shall be conducted
separately for each pressure relief device that had a release. If the
initial root cause analysis indicates that the release events have the
same root cause(s), the initially separate root cause analyses may be
recorded as a single root cause analysis and a single corrective action
analysis may be conducted.
(7) Corrective action implementation. Each owner or operator
required to conduct a root cause analysis and corrective action analysis
as specified in paragraphs (j)(3)(iii) and (j)(6) of this section shall
implement the corrective action(s) identified in the corrective action
analysis in accordance with the applicable requirements in paragraphs
(j)(7)(i) through (iii) of this section.
(i) All corrective action(s) must be implemented within 45 days of
the event for which the root cause and corrective action analyses were
required or as soon thereafter as practicable. If an owner or operator
concludes that no corrective action should be implemented, the owner or
operator shall record and explain the basis for that conclusion no later
than 45 days following the event.
(ii) For corrective actions that cannot be fully implemented within
45 days following the event for which the root cause and corrective
action analyses were required, the owner or operator shall develop an
implementation schedule to complete the corrective action(s) as soon as
practicable.
(iii) No later than 45 days following the event for which a root
cause and corrective action analyses were required, the owner or
operator shall record the corrective action(s) completed to date, and,
for action(s) not already completed, a schedule for implementation,
including proposed commencement and completion dates.

number (i.e., the total number of connectors removed minus the
total added) of connectors in organic HAP service removed from
the process unit after the applicability date set forth in
Sec. 63.640(h)(3)(iii) for existing process units, and after
the date of start-up for new process units. If credits are not
taken, then Cc = 0.

program to comply with the provisions in Sec. 63.174 of this part.
(e) Delay of repair of connectors for which leaks have been detected
is allowed if repair is not technically feasible by normal repair
techniques without a process unit shutdown. Repair of this equipment
shall occur by the end of the next process unit shutdown.
(1) Delay of repair is allowed for equipment that is isolated from
the process and that does not remain in organic HAP service.
(2) Delay of repair for connectors is also allowed if:
(i) The owner or operator determines that emissions of purged
material resulting from immediate repair would be greater than the
fugitive emissions likely to result from delay of repair, and
(ii) When repair procedures are accomplished, the purged material
would be collected and destroyed or recovered in a control device.

Sec. 63.652 Emissions averaging provisions.
(a) This section applies to owners or operators of existing sources
who seek to comply with the emission standard in Sec. 63.642(g) by
using emissions averaging according to Sec. 63.642(l) rather than
following the provisions of Sec. Sec. 63.643 through 63.645, 63.646 or
63.660, 63.647, 63.650, and 63.651. Existing marine tank vessel loading
operations located at the Valdez Marine Terminal source may not comply
with the standard by using emissions averaging.
(b) The owner or operator shall develop and submit for approval an
Implementation Plan containing all of the information required in Sec.
63.653(d) for all points to be included in an emissions average. The
Implementation Plan shall identify all emission points to be included in
the emissions average. This must include any Group 1 emission points to
which the reference control technology (defined in Sec. 63.641) is not
applied and all other emission points being controlled as part of the
average.
(c) The following emission points can be used to generate emissions
averaging credits if control was applied after November 15, 1990 and if
sufficient information is available to determine the appropriate value
of credits for the emission point:
(1) Group 2 emission points;
(2) Group 1 storage vessels, Group 1 wastewater streams, Group 1
gasoline
[[Page 84]]
loading racks, Group 1 marine tank vessels, and Group 1 miscellaneous
process vents that are controlled by a technology that the Administrator
or permitting authority agrees has a higher nominal efficiency than the
reference control technology. Information on the nominal efficiencies
for such technologies must be submitted and approved as provided in
paragraph (i) of this section; and
(3) Emission points from which emissions are reduced by pollution
prevention measures. Percentages of reduction for pollution prevention
measures shall be determined as specified in paragraph (j) of this
section.
(i) For a Group 1 emission point, the pollution prevention measure
must reduce emissions more than the reference control technology would
have had the reference control technology been applied to the emission
point instead of the pollution prevention measure except as provided in
paragraph (c)(3)(ii) of this section.
(ii) If a pollution prevention measure is used in conjunction with
other controls for a Group 1 emission point, the pollution prevention
measure alone does not have to reduce emissions more than the reference
control technology, but the combination of the pollution prevention
measure and other controls must reduce emissions more than the reference
control technology would have had it been applied instead.
(d) The following emission points cannot be used to generate
emissions averaging credits:
(1) Emission points already controlled on or before November 15,
1990 unless the level of control is increased after November 15, 1990,
in which case credit will be allowed only for the increase in control
after November 15, 1990;
(2) Group 1 emission points that are controlled by a reference
control technology unless the reference control technology has been
approved for use in a different manner and a higher nominal efficiency
has been assigned according to the procedures in paragraph (i) of this
section. For example, it is not allowable to claim that an internal
floating roof meeting only the specifications stated in the reference
control technology definition in Sec. 63.641 (i.e., that meets the
specifications of Sec. 63.119(b) of subpart G but does not have
controlled fittings per Sec. 63.119 (b)(5) and (b)(6) of subpart G)
applied to a storage vessel is achieving greater than 95 percent
control;
(3) Emission points on shutdown process units. Process units that
are shut down cannot be used to generate credits or debits;
(4) Wastewater that is not process wastewater or wastewater streams
treated in biological treatment units. These two types of wastewater
cannot be used to generate credits or debits. Group 1 wastewater streams
cannot be left undercontrolled or uncontrolled to generate debits. For
the purposes of this section, the terms ``wastewater'' and ``wastewater
stream'' are used to mean process wastewater; and
(5) Emission points controlled to comply with a State or Federal
rule other than this subpart, unless the level of control has been
increased after November 15, 1990 above what is required by the other
State or Federal rule. Only the control above what is required by the
other State or Federal rule will be credited. However, if an emission
point has been used to generate emissions averaging credit in an
approved emissions average, and the point is subsequently made subject
to a State or Federal rule other than this subpart, the point can
continue to generate emissions averaging credit for the purpose of
complying with the previously approved average.
(e) For all points included in an emissions average, the owner or
operator shall:
(1) Calculate and record monthly debits for all Group 1 emission
points that are controlled to a level less stringent than the reference
control technology for those emission points. Equations in paragraph (g)
of this section shall be used to calculate debits.
(2) Calculate and record monthly credits for all Group 1 or Group 2
emission points that are overcontrolled to compensate for the debits.
Equations in paragraph (h) of this section shall be used to calculate
credits. Emission points and controls that meet the criteria of
paragraph (c) of this section
[[Page 85]]
may be included in the credit calculation, whereas those described in
paragraph (d) of this section shall not be included.
(3) Demonstrate that annual credits calculated according to
paragraph (h) of this section are greater than or equal to debits
calculated for the same annual compliance period according to paragraph
(g) of this section.
(i) The initial demonstration in the Implementation Plan that
credit-generating emission points will be capable of generating
sufficient credits to offset the debits from the debit-generating
emission points must be made under representative operating conditions.
(ii) After the compliance date, actual operating data will be used
for all debit and credit calculations.
(4) Demonstrate that debits calculated for a quarterly (3-month)
period according to paragraph (g) of this section are not more than 1.30
times the credits for the same period calculated according to paragraph
(h) of this section. Compliance for the quarter shall be determined
based on the ratio of credits and debits from that quarter, with 30
percent more debits than credits allowed on a quarterly basis.
(5) Record and report quarterly and annual credits and debits in the
Periodic Reports as specified in Sec. 63.655(g)(8). Every fourth
Periodic Report shall include a certification of compliance with the
emissions averaging provisions as required by Sec. 63.655(g)(8)(iii).
(f) Debits and credits shall be calculated in accordance with the
methods and procedures specified in paragraphs (g) and (h) of this
section, respectively, and shall not include emissions from the
following:
(1) More than 20 individual emission points. Where pollution
prevention measures (as specified in paragraph (j)(1) of this section)
are used to control emission points to be included in an emissions
average, no more than 25 emission points may be included in the average.
For example, if two emission points to be included in an emissions
average are controlled by pollution prevention measures, the average may
include up to 22 emission points.
(2) [Reserved]
(3) For emission points for which continuous monitors are used,
periods of excess emissions as defined in Sec. 63.655(g)(6)(i). For
these periods, the calculation of monthly credits and debits shall be
adjusted as specified in paragraphs (f)(3)(i) through (f)(3)(iii) of
this section.
(i) No credits would be assigned to the credit-generating emission
point.
(ii) Maximum debits would be assigned to the debit-generating
emission point.
(iii) The owner or operator may use the procedures in paragraph (l)
of this section to demonstrate to the Administrator that full or partial
credits or debits should be assigned.
(g) Debits are generated by the difference between the actual
emissions from a Group 1 emission point that is uncontrolled or is
controlled to a level less stringent than the reference control
technology, and the emissions allowed for Group 1 emission point. Debits
shall be calculated as follows:
(1) The overall equation for calculating sourcewide debits is:

process or product recovery equipment or operation such that the
previously measured values of Q, Cj, and Mj are no
longer representative, a new performance test shall be conducted to

of emissions while the same product is produced.
(ii) Pollution prevention measures may include: Substitution of
feedstocks that reduce HAP emissions, alterations to the production
process to reduce the volume of materials released to the environment,
equipment modifications; housekeeping measures, and in-process recycling

(v) For the purposes of the equations in paragraphs (h)(2) through
(h)(6) of this section used to calculate credits for emission points
controlled more stringently than the reference control technology, the
nominal efficiency of a pollution prevention measure is equivalent to
the percentage of reduction of the pollution prevention measure. When a
pollution prevention measure is used, the owner or operator of a
[[Page 101]]
source is not required to apply to the Administrator for a nominal
efficiency and is not subject to paragraph (i) of this section.
(k) The owner or operator shall demonstrate that the emissions from
the emission points proposed to be included in the average will not
result in greater hazard or, at the option of the State or local
permitting authority, greater risk to human health or the environment
than if the emission points were controlled according to the provisions
in Sec. Sec. 63.643 through 63.645, 63.646 or 63.660, 63.647, 63.650,
and 63.651, as applicable.
(1) This demonstration of hazard or risk equivalency shall be made
to the satisfaction of the State or local permitting authority.
(i) The State or local permitting authority may require owners and
operators to use specific methodologies and procedures for making a
hazard or risk determination.
(ii) The demonstration and approval of hazard or risk equivalency
may be made according to any guidance that the EPA makes available for
use.
(2) Owners and operators shall provide documentation demonstrating
the hazard or risk equivalency of their proposed emissions average in
their Implementation Plan.
(3) An emissions averaging plan that does not demonstrate an
equivalent or lower hazard or risk to the satisfaction of the State or
local permitting authority shall not be approved. The State or local
permitting authority may require such adjustments to the emissions
averaging plan as are necessary in order to ensure that the average will
not result in greater hazard or risk to human health or the environment
than would result if the emission points were controlled according to
Sec. Sec. 63.643 through 63.645, 63.646 or 63.660, 63.647, 63.650, and
63.651, as applicable.
(4) A hazard or risk equivalency demonstration shall:
(i) Be a quantitative, bona fide chemical hazard or risk assessment;
(ii) Account for differences in chemical hazard or risk to human
health or the environment; and
(iii) Meet any requirements set by the State or local permitting
authority for such demonstrations.
(l) For periods of excess emissions, an owner or operator may
request that the provisions of paragraphs (l)(1) through (l)(4) of this
section be followed instead of the procedures in paragraphs (f)(3)(i)
and (f)(3)(ii) of this section.
(1) The owner or operator shall notify the Administrator of excess
emissions in the Periodic Reports as required in Sec. 63.655(g)(6).
(2) The owner or operator shall demonstrate that other types of
monitoring data or engineering calculations are appropriate to establish
that the control device for the emission point was operating in such a
fashion to warrant assigning full or partial credits and debits. This
demonstration shall be made to the Administrator's satisfaction, and the
Administrator may establish procedures for demonstrating compliance that
are acceptable.
(3) The owner or operator shall provide documentation of the period
of excess emissions and the other type of monitoring data or engineering
calculations to be used to demonstrate that the control device for the
emission point was operating in such a fashion to warrant assigning full
or partial credits and debits.
(4) The Administrator may assign full or partial credit and debits
upon review of the information provided.

Sec. 63.654 Heat exchange systems.
(a) Except as specified in paragraph (b) of this section, the owner
or operator of a heat exchange system that meets the criteria in Sec.
63.640(c)(8) must comply with the requirements of paragraphs (c) through
(g) of this section.
(b) A heat exchange system is exempt from the requirements in
paragraphs (c) through (g) of this section if all heat exchangers within
the heat exchange system either:
(1) Operate with the minimum pressure on the cooling water side at
least 35 kilopascals greater than the maximum pressure on the process
side; or
(2) Employ an intervening cooling fluid containing less than 5
percent by weight of total organic HAP, as determined according to the
provisions of Sec. 63.180(d) of this part and table 1 of this subpart,
between the process and the cooling water. This intervening fluid must
serve to isolate the cooling water from the process fluid and must not
be sent through a cooling tower or discharged. For purposes of this
section, discharge does not include emptying for maintenance purposes.
(c) The owner or operator must perform monitoring to identify leaks
of total strippable volatile organic compounds (VOC) from each heat
exchange system subject to the requirements of this subpart according to
the procedures in paragraphs (c)(1) through (6) of this section.
(1) Monitoring locations for closed-loop recirculation heat exchange
systems. For each closed loop recirculating heat exchange system,
collect and analyze a sample from the location(s) described in either
paragraph (c)(1)(i) or (c)(1)(ii) of this section.
(i) Each cooling tower return line or any representative riser
within the cooling tower prior to exposure to air for each heat exchange
system.
(ii) Selected heat exchanger exit line(s) so that each heat
exchanger or group of heat exchangers within a heat exchange system is
covered by the selected monitoring location(s).
(2) Monitoring locations for once-through heat exchange systems. For
each once-through heat exchange system, collect and analyze a sample
from the location(s) described in paragraph (c)(2)(i) of this section.
The owner or operator may also elect to collect and analyze an
additional sample from the location(s) described in paragraph (c)(2)(ii)
of this section.
(i) Selected heat exchanger exit line(s) so that each heat exchanger
or group of heat exchangers within a heat exchange system is covered by
the selected monitoring location(s). The selected monitoring location
may be at a point where discharges from multiple heat exchange systems
are combined provided that the combined cooling water flow rate at the
monitoring location does not exceed 40,000 gallons per minute.
(ii) The inlet water feed line for a once-through heat exchange
system prior to any heat exchanger. If multiple heat exchange systems
use the same water feed (i.e., inlet water from the same primary water
source), the owner or operator may monitor at one representative
location and use the
[[Page 105]]
monitoring results for that sampling location for all heat exchange
systems that use that same water feed.
(3) Monitoring method. Determine the total strippable hydrocarbon
concentration (in parts per million by volume (ppmv) as methane) at each
monitoring location using the ``Air Stripping Method (Modified El Paso
Method) for Determination of Volatile Organic Compound Emissions from
Water Sources'' Revision Number One, dated January 2003, Sampling
Procedures Manual, Appendix P: Cooling Tower Monitoring, prepared by
Texas Commission on Environmental Quality, January 31, 2003
(incorporated by reference--see Sec. 63.14) using a flame ionization
detector (FID) analyzer for on-site determination as described in
Section 6.1 of the Modified El Paso Method.
(4) Monitoring frequency and leak action level for existing sources.
For a heat exchange system at an existing source, the owner or operator
must comply with the monitoring frequency and leak action level as
defined in paragraph (c)(4)(i) of this section or comply with the
monitoring frequency and leak action level as defined in paragraph
(c)(4)(ii) of this section. The owner or operator of an affected heat
exchange system may choose to comply with paragraph (c)(4)(i) of this
section for some heat exchange systems at the petroleum refinery and
comply with paragraph (c)(4)(ii) of this section for other heat exchange
systems. However, for each affected heat exchange system, the owner or
operator of an affected heat exchange system must elect one monitoring
alternative that will apply at all times. If the owner or operator
intends to change the monitoring alternative that applies to a heat
exchange system, the owner or operator must notify the Administrator 30
days in advance of such a change. All ``leaks'' identified prior to
changing monitoring alternatives must be repaired. The monitoring
frequencies specified in paragraphs (c)(4)(i) and (ii) of this section
also apply to the inlet water feed line for a once-through heat exchange
system, if monitoring of the inlet water feed is elected as provided in
paragraph (c)(2)(ii) of this section.
(i) Monitor monthly using a leak action level defined as a total
strippable hydrocarbon concentration (as methane) in the stripping gas
of 6.2 ppmv.
(ii) Monitor quarterly using a leak action level defined as a total
strippable hydrocarbon concentration (as methane) in the stripping gas
of 3.1 ppmv unless repair is delayed as provided in paragraph (f) of
this section. If a repair is delayed as provided in paragraph (f) of
this section, monitor monthly.
(5) Monitoring frequency and leak action level for new sources. For
a heat exchange system at a new source, the owner or operator must
monitor monthly using a leak action level defined as a total strippable
hydrocarbon concentration (as methane) in the stripping gas of 3.1 ppmv.
(6) Leak definition. A leak is defined as described in paragraph
(c)(6)(i) or (c)(6)(ii) of this section, as applicable.
(i) For once-through heat exchange systems for which the inlet water
feed is monitored as described in paragraph (c)(2)(ii) of this section,
a leak is detected if the difference in the measurement value of the
sample taken from a location specified in paragraph (c)(2)(i) of this
section and the measurement value of the corresponding sample taken from
the location specified in paragraph (c)(2)(ii) of this section equals or
exceeds the leak action level.
(ii) For all other heat exchange systems, a leak is detected if a
measurement value of the sample taken from a location specified in
either paragraph (c)(1)(i), (c)(1)(ii), or (c)(2)(i) of this section
equals or exceeds the leak action level.
(d) If a leak is detected, the owner or operator must repair the
leak to reduce the measured concentration to below the applicable action
level as soon as practicable, but no later than 45 days after
identifying the leak, except as specified in paragraphs (e) and (f) of
this section. Repair includes re-monitoring at the monitoring location
where the leak was identified according to the method specified in
paragraph (c)(3) of this section to verify that the measured
concentration is below the applicable action level. Actions that can be
taken to achieve repair include but are not limited to:
[[Page 106]]
(1) Physical modifications to the leaking heat exchanger, such as
welding the leak or replacing a tube;
(2) Blocking the leaking tube within the heat exchanger;
(3) Changing the pressure so that water flows into the process
fluid;
(4) Replacing the heat exchanger or heat exchanger bundle; or
(5) Isolating, bypassing, or otherwise removing the leaking heat
exchanger from service until it is otherwise repaired.
(e) If the owner or operator detects a leak when monitoring a
cooling tower return line under paragraph (c)(1)(i) of this section, the
owner or operator may conduct additional monitoring of each heat
exchanger or group of heat exchangers associated with the heat exchange
system for which the leak was detected as provided under paragraph
(c)(1)(ii) of this section. If no leaks are detected when monitoring
according to the requirements of paragraph (c)(1)(ii) of this section,
the heat exchange system is considered to meet the repair requirements
through re-monitoring of the heat exchange system as provided in
paragraph (d) of this section.
(f) The owner or operator may delay the repair of a leaking heat
exchanger when one of the conditions in paragraph (f)(1) or (f)(2) of
this section is met and the leak is less than the delay of repair action
level specified in paragraph (f)(3) of this section. The owner or
operator must determine if a delay of repair is necessary as soon as
practicable, but no later than 45 days after first identifying the leak.
(1) If the repair is technically infeasible without a shutdown and
the total strippable hydrocarbon concentration is initially and remains
less than the delay of repair action level for all monthly monitoring
periods during the delay of repair, the owner or operator may delay
repair until the next scheduled shutdown of the heat exchange system.
If, during subsequent monthly monitoring, the delay of repair action
level is exceeded, the owner or operator must repair the leak within 30
days of the monitoring event in which the leak was equal to or exceeded
the delay of repair action level.
(2) If the necessary equipment, parts, or personnel are not
available and the total strippable hydrocarbon concentration is
initially and remains less than the delay of repair action level for all
monthly monitoring periods during the delay of repair, the owner or
operator may delay the repair for a maximum of 120 calendar days. The
owner or operator must demonstrate that the necessary equipment, parts,
or personnel were not available. If, during subsequent monthly
monitoring, the delay of repair action level is exceeded, the owner or
operator must repair the leak within 30 days of the monitoring event in
which the leak was equal to or exceeded the delay of repair action
level.
(3) The delay of repair action level is a total strippable
hydrocarbon concentration (as methane) in the stripping gas of 62 ppmv.
The delay of repair action level is assessed as described in paragraph
(f)(3)(i) or (f)(3)(ii) of this section, as applicable.
(i) For once-through heat exchange systems for which the inlet water
feed is monitored as described in paragraph (c)(2)(ii) of this section,
the delay of repair action level is exceeded if the difference in the
measurement value of the sample taken from a location specified in
paragraph (c)(2)(i) of this section and the measurement value of the
corresponding sample taken from the location specified in paragraph
(c)(2)(ii) of this section equals or exceeds the delay of repair action
level.
(ii) For all other heat exchange systems, the delay of repair action
level is exceeded if a measurement value of the sample taken from a
location specified in either paragraphs (c)(1)(i), (c)(1)(ii), or
(c)(2)(i) of this section equals or exceeds the delay of repair action
level.
(g) To delay the repair under paragraph (f) of this section, the
owner or operator must record the information in paragraphs (g)(1)
through (4) of this section.
(1) The reason(s) for delaying repair.
(2) A schedule for completing the repair as soon as practical.
(3) The date and concentration of the leak as first identified and
the results of all subsequent monthly monitoring events during the delay
of repair.
[[Page 107]]
(4) An estimate of the potential strippable hydrocarbon emissions
from the leaking heat exchange system or heat exchanger for each
required delay of repair monitoring interval following the procedures in
paragraphs (g)(4)(i) through (iv) of this section.
(i) Determine the leak concentration as specified in paragraph (c)
of this section and convert the stripping gas leak concentration (in
ppmv as methane) to an equivalent liquid concentration, in parts per
million by weight (ppmw), using equation 7-1 from ``Air Stripping Method
(Modified El Paso Method) for Determination of Volatile Organic Compound
Emissions from Water Sources'' Revision Number One, dated January 2003,
Sampling Procedures Manual, Appendix P: Cooling Tower Monitoring,
prepared by Texas Commission on Environmental Quality, January 31, 2003
(incorporated by reference--see Sec. 63.14) and the molecular weight of
16 grams per mole (g/mol) for methane.
(ii) Determine the mass flow rate of the cooling water at the
monitoring location where the leak was detected. If the monitoring
location is an individual cooling tower riser, determine the total
cooling water mass flow rate to the cooling tower. Cooling water mass
flow rates may be determined using direct measurement, pump curves, heat
balance calculations, or other engineering methods. Volumetric flow
measurements may be used and converted to mass flow rates using the
density of water at the specific monitoring location temperature or
using the default density of water at 25 degrees Celsius, which is 997
kilograms per cubic meter or 8.32 pounds per gallon.
(iii) For delay of repair monitoring intervals prior to repair of
the leak, calculate the potential strippable hydrocarbon emissions for
the leaking heat exchange system or heat exchanger for the monitoring
interval by multiplying the leak concentration in the cooling water,
ppmw, determined in (g)(4)(i) of this section, by the mass flow rate of
the cooling water determined in (g)(4)(ii) of this section and by the
duration of the delay of repair monitoring interval. The duration of the
delay of repair monitoring interval is the time period starting at
midnight on the day of the previous monitoring event or at midnight on
the day the repair would have had to be completed if the repair had not
been delayed, whichever is later, and ending at midnight of the day the
of the current monitoring event.
(iv) For delay of repair monitoring intervals ending with a repaired
leak, calculate the potential strippable hydrocarbon emissions for the
leaking heat exchange system or heat exchanger for the final delay of
repair monitoring interval by multiplying the duration of the final
delay of repair monitoring interval by the leak concentration and
cooling water flow rates determined for the last monitoring event prior
to the re-monitoring event used to verify the leak was repaired. The
duration of the final delay of repair monitoring interval is the time
period starting at midnight of the day of the last monitoring event
prior to re-monitoring to verify the leak was repaired and ending at the
time of the re-monitoring event that verified that the leak was
repaired.

time beginning 5 business days prior to the date that the submission is
due, you will be or are precluded from accessing CEDRI or CDX and
submitting a required report within the time prescribed, you may assert
a claim of EPA system outage for failure to timely comply with the
reporting requirement. You must submit notification to the Administrator
[[Page 121]]
in writing as soon as possible following the date you first knew, or
through due diligence should have known, that the event may cause or
caused a delay in reporting. You must provide to the Administrator a
written description identifying the date(s) and time(s) the CDX or CEDRI
were unavailable when you attempted to access it in the 5 business days
prior to the submission deadline; a rationale for attributing the delay
in reporting beyond the regulatory deadline to the EPA system outage;
describe the measures taken or to be taken to minimize the delay in
reporting; and identify a date by which you propose to report, or if you
have already met the reporting requirement at the time of the
notification, the date you reported. In any circumstance, the report
must be submitted electronically as soon as possible after the outage is
resolved. The decision to accept the claim of EPA system outage and
allow an extension to the reporting deadline is solely within the
discretion of the Administrator.
(ii) If you are required to electronically submit a report through
CEDRI in the EPA's CDX and a force majeure event is about to occur,
occurs, or has occurred or there are lingering effects from such an
event within the period of time beginning 5 business days prior to the
date the submission is due, the owner or operator may assert a claim of
force majeure for failure to timely comply with the reporting
requirement. For the purposes of this paragraph, a force majeure event
is defined as an event that will be or has been caused by circumstances
beyond the control of the affected facility, its contractors, or any
entity controlled by the affected facility that prevents you from
complying with the requirement to submit a report electronically within
the time period prescribed. Examples of such events are acts of nature
(e.g., hurricanes, earthquakes, or floods), acts of war or terrorism, or
equipment failure or safety hazard beyond the control of the affected
facility (e.g., large scale power outage). If you intend to assert a
claim of force majeure, you must submit notification to the
Administrator in writing as soon as possible following the date you
first knew, or through due diligence should have known, that the event
may cause or caused a delay in reporting. You must provide to the
Administrator a written description of the force majeure event and a
rationale for attributing the delay in reporting beyond the regulatory
deadline to the force majeure event; describe the measures taken or to
be taken to minimize the delay in reporting; and identify a date by
which you propose to report, or if you have already met the reporting
requirement at the time of the notification, the date you reported. In
any circumstance, the reporting must occur as soon as possible after the
force majeure event occurs. The decision to accept the claim of force
majeure and allow an extension to the reporting deadline is solely
within the discretion of the Administrator.

practice for monitoring equipment for leaks, the leak definitions
contained in Sec. 63.11 (c)(6)(i) through (iii).
(iii) All equipment leak sources in organic HAP service, including
sources in gas, light liquid and heavy liquid service, must be inspected
using visual, audible, olfactory, or any other detection method at least
monthly. A leak is detected if the inspection identifies a potential
leak to the atmosphere or if there are indications of liquids dripping.
(iv) All leaks identified by the monitoring or inspections specified
in paragraphs (c)(1)(ii) or (iii) of this section must be repaired no
later than 15 calendar days after it is detected with no provisions for
delay of repair. If a repair is not completed within 15 calendar days,
the additional passive monitor specified in Section 8.2.1.3 in Method
325A of appendix A of this part must be used.
(2) The owner or operator may collect one or more background samples
if the owner or operator believes that an offsite upwind source or an
onsite source excluded under Sec. 63.640(g) may influence the sampler
measurements. If the owner or operator elects to collect one or more
background samples, the owner or operator must develop and submit a
site-specific monitoring plan for approval according to the requirements
in paragraph (i) of this section. Upon approval of the site-specific
monitoring plan, the background sampler(s) should be operated co-
currently with the routine samplers.
(3) If there are 19 or fewer monitoring locations, the owner or
operator shall collect at least one co-located duplicate sample per
sampling period and at least one field blank per sampling period. If
there are 20 or more monitoring locations, the owner or operator shall
collect at least two co-located duplicate samples per sampling period
and
[[Page 131]]
at least one field blank per sampling period. The co-located duplicates
may be collected at any of the perimeter sampling.
(4) The owner or operator shall follow the procedure in Section 9.6
of Method 325B of appendix A of this part to determine the detection
limit of benzene for each sampler used to collect samples, background
samples (if the owner or operator elects to do so), co-located samples
and blanks.
(d) The owner or operator shall collect and record meteorological
data according to the applicable requirements in paragraphs (d)(1)
through (3) of this section.
(1) If a near-field source correction is used as provided in
paragraph (i)(2) of this section or if an alternative test method is
used that provides time-resolved measurements, the owner or operator
shall:
(i) Use an on-site meteorological station in accordance with Section
8.3 of Method 325A of appendix A of this part.
(ii) Collect and record hourly average meteorological data,
including temperature, barometric pressure, wind speed and wind
direction and calculate daily unit vector wind direction and daily sigma
theta.
(2) For cases other than those specified in paragraph (d)(1) of this
section, the owner or operator shall collect and record sampling period
average temperature and barometric pressure using either an on-site
meteorological station in accordance with Section 8.3.1 through 8.3.3 of
Method 325A of appendix A of this part or, alternatively, using data
from a United States Weather Service (USWS) meteorological station
provided the USWS meteorological station is within 40 kilometers (25
miles) of the refinery.
(3) If an on-site meteorological station is used, the owner or
operator shall follow the calibration and standardization procedures for
meteorological measurements in EPA-454/B-08-002 (incorporated by
reference--see Sec. 63.14).
(e) The owner or operator shall use a sampling period and sampling
frequency as specified in paragraphs (e)(1) through (3) of this section.
(1) Sampling period. A 14-day sampling period shall be used, unless
a shorter sampling period is determined to be necessary under paragraph
(g) or (i) of this section. A sampling period is defined as the period
during which sampling tube is deployed at a specific sampling location
with the diffusive sampling end cap in-place and does not include the
time required to analyze the sample. For the purpose of this subpart, a
14-day sampling period may be no shorter than 13 calendar days and no
longer than 15 calendar days, but the routine sampling period shall be
14 calendar days.
(2) Base sampling frequency. Except as provided in paragraph (e)(3)
of this section, the frequency of sample collection shall be once each
contiguous 14-day sampling period, such that the beginning of the next
14-day sampling period begins immediately upon the completion of the
previous 14-day sampling period.
(3) Alternative sampling frequency for burden reduction. When an
individual monitor consistently achieves results at or below 0.9
[micro]g/m\3\, the owner or operator may elect to use the applicable
minimum sampling frequency specified in paragraphs (e)(3)(i) through (v)
of this section for that monitoring site. When calculating [Delta]c for
the monitoring period when using this alternative for burden reduction,
zero shall be substituted for the sample result for the monitoring site
for any period where a sample is not taken.
(i) If every sample at a monitoring site is at or below 0.9
[micro]g/m\3\ for 2 years (52 consecutive samples), every other sampling
period can be skipped for that monitoring site, i.e., sampling will
occur approximately once per month.
(ii) If every sample at a monitoring site that is monitored at the
frequency specified in paragraph (e)(3)(i) of this section is at or
below 0.9 [micro]g/m\3\ for 2 years (i.e., 26 consecutive ``monthly''
samples), five 14-day sampling periods can be skipped for that
monitoring site following each period of sampling, i.e., sampling will
occur approximately once per quarter.
(iii) If every sample at a monitoring site that is monitored at the
frequency specified in paragraph (e)(3)(ii) of this section is at or
below 0.9 [micro]g/m\3\ for 2 years (i.e., 8 consecutive quarterly
samples), twelve 14-day sampling periods can be skipped for that
monitoring site
[[Page 132]]
following each period of sampling, i.e., sampling will occur twice a
year.
(iv) If every sample at a monitoring site that is monitored at the
frequency specified in paragraph (e)(3)(iii) of this section is at or
below 0.9 [micro]g/m\3\ for 2 years (i.e., 4 consecutive semiannual
samples), only one sample per year is required for that monitoring site.
For yearly sampling, samples shall occur at least 10 months but no more
than 14 months apart.
(v) If at any time a sample for a monitoring site that is monitored
at the frequency specified in paragraphs (e)(3)(i) through (iv) of this
section returns a result that is above 0.9 [micro]g/m\3\, the sampling
site must return to the original sampling requirements of contiguous 14-
day sampling periods with no skip periods for one quarter (six 14-day
sampling periods). If every sample collected during this quarter is at
or below 0.9 [micro]g/m\3\ , the owner or operator may revert back to
the reduced monitoring schedule applicable for that monitoring site
prior to the sample reading exceeding 0.9 [micro]g/m\3\ If any sample
collected during this quarter is above 0.9 [micro]g/m\3\, that
monitoring site must return to the original sampling requirements of
contiguous 14-day sampling periods with no skip periods for a minimum of
two years. The burden reduction requirements can be used again for that
monitoring site once the requirements of paragraph (e)(3)(i) of this
section are met again, i.e., after 52 contiguous 14-day samples with no
results above 0.9 [micro]g/m\3\ .
(f) Within 45 days of completion of each sampling period, the owner
or operator shall determine whether the results are above or below the
action level as follows:
(1) The owner or operator shall determine the facility impact on the
benzene concentration ([Delta]c) for each 14-day sampling period
according to either paragraph (f)(1)(i) or (ii) of this section, as
applicable.
(i) Except when near-field source correction is used as provided in
paragraph (i) of this section, the owner or operator shall determine the
highest and lowest sample results for benzene concentrations from the
sample pool and calculate [Delta]c as the difference in these
concentrations. Co-located samples must be averaged together for the
purposes of determining the benzene concentration for that sampling
location, and, if applicable, for determining [Delta]c. The owner or
operator shall adhere to the following procedures when one or more
samples for the sampling period are below the method detection limit for
benzene:
(A) If the lowest detected value of benzene is below detection, the
owner or operator shall use zero as the lowest sample result when
calculating [Delta]c.
(B) If all sample results are below the method detection limit, the
owner or operator shall use the method detection limit as the highest
sample result and zero as the lowest sample result when calculating
[Delta]c.
(ii) When near-field source correction is used as provided in
paragraph (i) of this section, the owner or operator shall determine
[Delta]c using the calculation protocols outlined in the approved site-
specific monitoring plan and in paragraph (i) of this section.
(2) The owner or operator shall calculate the annual average
[Delta]c based on the average of the 26 most recent 14-day sampling
periods. The owner or operator shall update this annual average value
after receiving the results of each subsequent 14-day sampling period.
(3) The action level for benzene is 9 micrograms per cubic meter
([micro]g/m3) on an annual average basis. If the annual average [Delta]c
value for benzene is less than or equal to 9 [micro]g/m\3\, the
concentration is below the action level. If the annual average [Delta]c
value for benzene is greater than 9 [micro]g/m\3\, the concentration is
above the action level, and the owner or operator shall conduct a root
cause analysis and corrective action in accordance with paragraph (g) of
this section.
(g) Within 5 days of determining that the action level has been
exceeded for any annual average [Delta]c and no longer than 50 days
after completion of the sampling period, the owner or operator shall
initiate a root cause analysis to determine the cause of such exceedance
and to determine appropriate corrective action, such as those described
in paragraphs (g)(1) through (4) of this section. The root cause
analysis and initial corrective action analysis shall
[[Page 133]]
be completed and initial corrective actions taken no later than 45 days
after determining there is an exceedance. Root cause analysis and
corrective action may include, but is not limited to:
(1) Leak inspection using Method 21 of part 60, appendix A-7 of this
chapter and repairing any leaks found.
(2) Leak inspection using optical gas imaging and repairing any
leaks found.
(3) Visual inspection to determine the cause of the high benzene
emissions and implementing repairs to reduce the level of emissions.
(4) Employing progressively more frequent sampling, analysis and
meteorology (e.g., using shorter sampling periods for Methods 325A and
325B of appendix A of this part, or using active sampling techniques).
(h) If, upon completion of the corrective action analysis and
corrective actions such as those described in paragraph (g) of this
section, the [Delta]c value for the next 14-day sampling period for
which the sampling start time begins after the completion of the
corrective actions is greater than 9 [micro]g/m\3\ or if all corrective
action measures identified require more than 45 days to implement, the
owner or operator shall develop a corrective action plan that describes
the corrective action(s) completed to date, additional measures that the
owner or operator proposes to employ to reduce fenceline concentrations
below the action level, and a schedule for completion of these measures.
The owner or operator shall submit the corrective action plan to the
Administrator within 60 days after receiving the analytical results
indicating that the [Delta]c value for the 14-day sampling period
following the completion of the initial corrective action is greater
than 9 [micro]g/m\3\ or, if no initial corrective actions were
identified, no later than 60 days following the completion of the
corrective action analysis required in paragraph (g) of this section.
(i) An owner or operator may request approval from the Administrator
for a site-specific monitoring plan to account for offsite upwind
sources or onsite sources excluded under Sec. 63.640(g) according to
the requirements in paragraphs (i)(1) through (4) of this section.
(1) The owner or operator shall prepare and submit a site-specific
monitoring plan and receive approval of the site-specific monitoring
plan prior to using the near-field source alternative calculation for
determining [Delta]c provided in paragraph (i)(2) of this section. The
site-specific monitoring plan shall include, at a minimum, the elements
specified in paragraphs (i)(1)(i) through (v) of this section. The
procedures in Section 12 of Method 325A of appendix A of this part are
not required, but may be used, if applicable, when determining near-
field source contributions.
(i) Identification of the near-field source or sources. For onsite
sources, documentation that the onsite source is excluded under Sec.
63.640(g) and identification of the specific provision in Sec.
63.640(g) that applies to the source.
(ii) Location of the additional monitoring stations that shall be
used to determine the uniform background concentration and the near-
field source concentration contribution.
(iii) Identification of the fenceline monitoring locations impacted
by the near-field source. If more than one near-field source is present,
identify the near-field source or sources that are expected to
contribute to the concentration at that monitoring location.
(iv) A description of (including sample calculations illustrating)
the planned data reduction and calculations to determine the near-field
source concentration contribution for each monitoring location.
(v) If more frequent monitoring or a monitoring station other than a
passive diffusive tube monitoring station is proposed, provide a
detailed description of the measurement methods, measurement frequency,
and recording frequency for determining the uniform background or near-
field source concentration contribution.
(2) When an approved site-specific monitoring plan is used, the
owner or operator shall determine [Delta]c for comparison with the 9
[micro]g/m\3\ action level using the requirements specified in
paragraphs (i)(2)(i) through (iii) of this section.
(i) For each monitoring location, calculate [Delta]ci
using the following equation.
[Delta]ci = MFCi - NFSi - UB
[[Page 134]]
Where:
[Delta]ci = The fenceline concentration, corrected for
background, at measurement location i, micrograms per cubic
meter ([micro]g/m\3\).
MFCi = The measured fenceline concentration at measurement
location i, [micro]g/m\3\.
NFSi = The near-field source contributing concentration at
measurement location i determined using the additional
measurements and calculation procedures included in the site-
specific monitoring plan, [micro]g/m\3\. For monitoring
locations that are not included in the site-specific
monitoring plan as impacted by a near-field source, use
NFSi = 0 [micro]g/m\3\.
UB = The uniform background concentration determined using the
additional measurements included in the site-specific
monitoring plan, [micro]g/m\3\. If no additional measurements
are specified in the site-specific monitoring plan for
determining the uniform background concentration, use UB = 0
[micro]g/m\3\.
(ii) When one or more samples for the sampling period are below the
method detection limit for benzene, adhere to the following procedures:
(A) If the benzene concentration at the monitoring location used for
the uniform background concentration is below the method detection
limit, the owner or operator shall use zero for UB for that monitoring
period.
(B) If the benzene concentration at the monitoring location(s) used
to determine the near-field source contributing concentration is below
the method detection limit, the owner or operator shall use zero for the
monitoring location concentration when calculating NFSi for
that monitoring period.
(C) If a fenceline monitoring location sample result is below the
method detection limit, the owner or operator shall use the method
detection limit as the sample result.
(iii) Determine [Delta]c for the monitoring period as the maximum
value of [Delta]ci from all of the fenceline monitoring
locations for that monitoring period.
(3) The site-specific monitoring plan shall be submitted and
approved as described in paragraphs (i)(3)(i) through (iv) of this
section.
(i) The site-specific monitoring plan must be submitted to the
Administrator for approval.
(ii) The site-specific monitoring plan shall also be submitted to
the following address: U.S. Environmental Protection Agency, Office of
Air Quality Planning and Standards, Sector Policies and Programs
Division, U.S. EPA Mailroom (E143-01), Attention: Refinery Sector Lead,
109 T.W. Alexander Drive, Research Triangle Park, NC 27711. Electronic
copies in lieu of hard copies may also be submitted to
[email protected].
(iii) The Administrator shall approve or disapprove the plan in 90
days. The plan shall be considered approved if the Administrator either
approves the plan in writing, or fails to disapprove the plan in
writing. The 90-day period shall begin when the Administrator receives
the plan.
(iv) If the Administrator finds any deficiencies in the site-
specific monitoring plan and disapproves the plan in writing, the owner
or operator may revise and resubmit the site-specific monitoring plan
following the requirements in paragraphs (i)(3)(i) and (ii) of this
section. The 90-day period starts over with the resubmission of the
revised monitoring plan.
(4) The approval by the Administrator of a site-specific monitoring
plan will be based on the completeness, accuracy and reasonableness of
the request for a site-specific monitoring plan. Factors that the
Administrator will consider in reviewing the request for a site-specific
monitoring plan include, but are not limited to, those described in
paragraphs (i)(4)(i) through (v) of this section.
(i) The identification of the near-field source or sources. For
onsite sources, the documentation provided that the onsite source is
excluded under Sec. 63.640(g).
(ii) The monitoring location selected to determine the uniform
background concentration or an indication that no uniform background
concentration monitor will be used.
(iii) The location(s) selected for additional monitoring to
determine the near-field source concentration contribution.
(iv) The identification of the fenceline monitoring locations
impacted by the near-field source or sources.
(v) The appropriateness of the planned data reduction and
calculations to determine the near-field
[[Page 135]]
source concentration contribution for each monitoring location.
(vi) If more frequent monitoring is proposed, the adequacy of the
description of the measurement and recording frequency proposed and the
adequacy of the rationale for using the alternative monitoring
frequency.
(j) The owner or operator shall comply with the applicable
recordkeeping and reporting requirements in Sec. 63.655(h) and (i).
(k) As outlined in Sec. 63.7(f), the owner or operator may submit a
request for an alternative test method. At a minimum, the request must
follow the requirements outlined in paragraphs (k)(1) through (7) of
this section.
(1) The alternative method may be used in lieu of all or a partial
number of passive samplers required in Method 325A of appendix A of this
part.
(2) The alternative method must be validated according to Method 301
in appendix A of this part or contain performance based procedures and
indicators to ensure self-validation.
(3) The method detection limit must nominally be at least an order
of magnitude below the action level, i.e., 0.9 [micro]g/m\3\ benzene.
The alternate test method must describe the procedures used to provide
field verification of the detection limit.
(4) The spatial coverage must be equal to or better than the spatial
coverage provided in Method 325A of appendix A of this part.
(i) For path average concentration open-path instruments, the
physical path length of the measurement shall be no more than a passive
sample footprint (the spacing that would be provided by the sorbent
traps when following Method 325A). For example, if Method 325A requires
spacing monitors A and B 610 meters (2000 feet) apart, then the physical
path length limit for the measurement at that portion of the fenceline
shall be no more than 610 meters (2000 feet).
(ii) For range resolved open-path instrument or approach, the
instrument or approach must be able to resolve an average concentration
over each passive sampler footprint within the path length of the
instrument.
(iii) The extra samplers required in Sections 8.2.1.3 of Method 325A
may be omitted when they fall within the path length of an open-path
instrument.
(5) At a minimum, non-integrating alternative test methods must
provide a minimum of one cycle of operation (sampling, analyzing, and
data recording) for each successive 15-minute period.
(6) For alternative test methods capable of real time measurements
(less than a 5 minute sampling and analysis cycle), the alternative test
method may allow for elimination of data points corresponding to outside
emission sources for purpose of calculation of the high point for the
two week average. The alternative test method approach must have wind
speed, direction and stability class of the same time resolution and
within the footprint of the instrument.
(7) For purposes of averaging data points to determine the [Delta]c
for the 14-day average high sample result, all results measured under
the method detection limit must use the method detection limit. For
purposes of averaging data points for the 14-day average low sample
result, all results measured under the method detection limit must use
zero.

closed vent system that contains bypass lines that could divert a vent
stream either directly to the atmosphere or to a control device that
does not comply with the requirements in subpart SS of this part. Except
as provided in paragraphs (i)(2)(i) and (ii) of this section, use of the
bypass at any time to divert a Group 1 storage vessel either directly to
the atmosphere or to a control device that does not comply with the

violation. Equipment such as low leg drains and equipment subject to
Sec. 63.648 are not subject to this paragraph (i)(2).
(i) If planned routine maintenance of the control device cannot be
performed during periods that storage vessel emissions are vented to the
control device or when the storage vessel is taken out of service for
inspections or other planned maintenance reasons, the owner or operator
may bypass the control device.
(ii) Periods for which storage vessel control device may be bypassed

ended valves or line following the requirements specified in Sec.
60.482-6(a)(2), (b) and (c).
(3) If storage vessel emissions are routed to a fuel gas system or
process, the fuel gas system or process shall be operating at all times
when regulated emissions are routed to it. The exception in Sec.
63.984(a)(1) does not apply.
[80 FR 75257, Dec. 1, 2015, as amended at 83 FR 60719, Nov. 26, 2018]
Sec. 63.670 Requirements for flare control devices.
On or before January 30, 2019, the owner or operator of a flare used
as a control device for an emission point subject to this subpart shall
meet the applicable requirements for flares as specified in paragraphs
(a) through (q) of this section and the applicable requirements in Sec.
63.671. The owner or operator may elect to comply with the requirements
of paragraph (r) of this section in lieu of the requirements in
paragraphs (d) through (f) of this section, as applicable.
(a) [Reserved]
(b) Pilot flame presence. The owner or operator shall operate each
flare with a
[[Page 138]]
pilot flame present at all times when regulated material is routed to
the flare. Each 15-minute block during which there is at least one
minute where no pilot flame is present when regulated material is routed
to the flare is a deviation of the standard. Deviations in different 15-
minute blocks from the same event are considered separate deviations.
The owner or operator shall monitor for the presence of a pilot flame as
specified in paragraph (g) of this section.
(c) Visible emissions. The owner or operator shall specify the
smokeless design capacity of each flare and operate with no visible
emissions, except for periods not to exceed a total of 5 minutes during
any 2 consecutive hours, when regulated material is routed to the flare
and the flare vent gas flow rate is less than the smokeless design
capacity of the flare. The owner or operator shall monitor for visible
emissions from the flare as specified in paragraph (h) of this section.
(d) Flare tip velocity. For each flare, the owner or operator shall
comply with either paragraph (d)(1) or (2) of this section, provided the
appropriate monitoring systems are in-place, whenever regulated material
is routed to the flare for at least 15-minutes and the flare vent gas
flow rate is less than the smokeless design capacity of the flare.
(1) Except as provided in paragraph (d)(2) of this section, the
actual flare tip velocity (Vtip) must be less than 60 feet
per second. The owner or operator shall monitor Vtipusing the
procedures specified in paragraphs (i) and (k) of this section.
(2) Vtip must be less than 400 feet per second and also
less than the maximum allowed flare tip velocity (Vmax) as
calculated according to the following equation. The owner or operator
shall monitor Vtip using the procedures specified in paragraphs (i) and
(k) of this section and monitor gas composition and determine
NHVvg using the procedures specified in paragraphs (j) and
(l) of this section.
[GRAPHIC] [TIFF OMITTED] TR01DE15.008
Where:
Vmax = Maximum allowed flare tip velocity, ft/sec.
NHVvg = Net heating value of flare vent gas, as determined by
paragraph (l)(4) of this section, Btu/scf.
1,212 = Constant.
850 = Constant.
(e) Combustion zone operating limits. For each flare, the owner or
operator shall operate the flare to maintain the net heating value of
flare combustion zone gas (NHVcz) at or above 270 British
thermal units per standard cubic feet (Btu/scf) determined on a 15-
minute block period basis when regulated material is routed to the flare
for at least 15-minutes. The owner or operator shall monitor and
calculate NHVcz as specified in paragraph (m) of this
section.
(f) Dilution operating limits for flares with perimeter assist air.
Except as provided in paragraph (f)(1) of this section, for each flare
actively receiving perimeter assist air, the owner or operator shall
operate the flare to maintain the net heating value dilution parameter
(NHVdil) at or above 22 British thermal units per square foot (Btu/
ft\2\) determined on a 15-minute block period basis when regulated
material is being routed to the flare for at least 15-minutes. The owner
or operator shall monitor and calculate NHVdil as specified
in paragraph (n) of this section.
(1) If the only assist air provided to a specific flare is perimeter
assist air intentionally entrained in lower and/or upper steam at the
flare tip and the effective diameter is 9 inches or greater, the owner
or operator shall comply only with the NHVcz operating limit
in paragraph (e) of this section for that flare.
(2) [Reserved]
[[Page 139]]
(g) Pilot flame monitoring. The owner or operator shall continuously
monitor the presence of the pilot flame(s) using a device (including,
but not limited to, a thermocouple, ultraviolet beam sensor, or infrared
sensor) capable of detecting that the pilot flame(s) is present.
(h) Visible emissions monitoring. The owner or operator shall
conduct an initial visible emissions demonstration using an observation
period of 2 hours using Method 22 at 40 CFR part 60, appendix A-7. The
initial visible emissions demonstration should be conducted the first
time regulated materials are routed to the flare. Subsequent visible
emissions observations must be conducted using either the methods in
paragraph (h)(1) of this section or, alternatively, the methods in
paragraph (h)(2) of this section. The owner or operator must record and
report any instances where visible emissions are observed for more than
5 minutes during any 2 consecutive hours as specified in Sec.
63.655(g)(11)(ii).
(1) At least once per day for each day regulated material is routed
to the flare, conduct visible emissions observations using an
observation period of 5 minutes using Method 22 at 40 CFR part 60,
appendix A-7. If at any time the owner or operator sees visible
emissions while regulated material is routed to the flare, even if the
minimum required daily visible emission monitoring has already been
performed, the owner or operator shall immediately begin an observation
period of 5 minutes using Method 22 at 40 CFR part 60, appendix A-7. If
visible emissions are observed for more than one continuous minute
during any 5-minute observation period, the observation period using
Method 22 at 40 CFR part 60, appendix A-7 must be extended to 2 hours or
until 5-minutes of visible emissions are observed. Daily 5-minute Method
22 observations are not required to be conducted for days the flare does
not receive any regulated material.
(2) Use a video surveillance camera to continuously record (at least
one frame every 15 seconds with time and date stamps) images of the
flare flame and a reasonable distance above the flare flame at an angle
suitable for visual emissions observations. The owner or operator must
provide real-time video surveillance camera output to the control room
or other continuously manned location where the camera images may be
viewed at any time.
(i) Flare vent gas, steam assist and air assist flow rate
monitoring. The owner or operator shall install, operate, calibrate, and
maintain a monitoring system capable of continuously measuring,
calculating, and recording the volumetric flow rate in the flare header
or headers that feed the flare as well as any flare supplemental gas
used. Different flow monitoring methods may be used to measure different
gaseous streams that make up the flare vent gas provided that the flow
rates of all gas streams that contribute to the flare vent gas are
determined. If assist air or assist steam is used, the owner or operator
shall install, operate, calibrate, and maintain a monitoring system
capable of continuously measuring, calculating, and recording the
volumetric flow rate of assist air and/or assist steam used with the
flare. If pre-mix assist air and perimeter assist are both used, the
owner or operator shall install, operate, calibrate, and maintain a
monitoring system capable of separately measuring, calculating, and
recording the volumetric flow rate of premix assist air and perimeter
assist air used with the flare. Flow monitoring system requirements and
acceptable alternatives are provided in paragraphs (i)(1) through (6) of
this section.
(1) The flow rate monitoring systems must be able to correct for the
temperature and pressure of the system and output parameters in standard
conditions (i.e., a temperature of 20 [deg]C (68 [deg]F) and a pressure
of 1 atmosphere).
(2) Mass flow monitors may be used for determining volumetric flow
rate of flare vent gas provided the molecular weight of the flare vent
gas is determined using compositional analysis as specified in paragraph
(j) of this section so that the mass flow rate can be converted to
volumetric flow at standard conditions using the following equation.
[[Page 140]]
[GRAPHIC] [TIFF OMITTED] TR01DE15.009
Where:
Qvol = Volumetric flow rate, standard cubic feet per second.
Qmass = Mass flow rate, pounds per second.
385.3 = Conversion factor, standard cubic feet per pound-mole.
MWt = Molecular weight of the gas at the flow monitoring location,
pounds per pound-mole.
(3) Mass flow monitors may be used for determining volumetric flow
rate of assist air or assist steam. Use equation in paragraph (i)(2) of
this section to convert mass flow rates to volumetric flow rates. Use a
molecular weight of 18 pounds per pound-mole for assist steam and use a
molecular weight of 29 pounds per pound-mole for assist air.
(4) Continuous pressure/temperature monitoring system(s) and
appropriate engineering calculations may be used in lieu of a continuous
volumetric flow monitoring systems provided the molecular weight of the
gas is known. For assist steam, use a molecular weight of 18 pounds per
pound-mole. For assist air, use a molecular weight of 29 pounds per
pound-mole. For flare vent gas, molecular weight must be determined
using compositional analysis as specified in paragraph (j) of this
section.
(5) Continuously monitoring fan speed or power and using fan curves
is an acceptable method for continuously monitoring assist air flow
rates.
(6) For perimeter assist air intentionally entrained in lower and/or
upper steam, the monitored steam flow rate and the maximum design air-
to-steam volumetric flow ratio of the entrainment system may be used to
determine the assist air flow rate.
(j) Flare vent gas composition monitoring. The owner or operator
shall determine the concentration of individual components in the flare
vent gas using either the methods provided in paragraph (j)(1) or (2) of
this section, to assess compliance with the operating limits in
paragraph (e) of this section and, if applicable, paragraphs (d) and (f)
of this section. Alternatively, the owner or operator may elect to
directly monitor the net heating value of the flare vent gas following
the methods provided in paragraphs (j)(3) of this section and, if
desired, may directly measure the hydrogen concentration in the flare
vent gas following the methods provided in paragraphs (j)(4) of this
section. The owner or operator may elect to use different monitoring
methods for different gaseous streams that make up the flare vent gas
using different methods provided the composition or net heating value of
all gas streams that contribute to the flare vent gas are determined.
(1) Except as provided in paragraphs (j)(5) and (6) of this section,
the owner or operator shall install, operate, calibrate, and maintain a
monitoring system capable of continuously measuring (i.e., at least once
every 15-minutes), calculating, and recording the individual component
concentrations present in the flare vent gas.
(2) Except as provided in paragraphs (j)(5) and (6) of this section,
the owner or operator shall install, operate, and maintain a grab
sampling system capable of collecting an evacuated canister sample for
subsequent compositional analysis at least once every eight hours while
there is flow of regulated material to the flare. Subsequent
compositional analysis of the samples must be performed according to
Method 18 of 40 CFR part 60, appendix A-6, ASTM D6420-99 (Reapproved
2010), ASTM D1945-03 (Reapproved 2010), ASTM D1945-14 or ASTM UOP539-12
(all incorporated by reference--see Sec. 63.14).
(3) Except as provided in paragraphs (j)(5) and (6) of this section,
the owner or operator shall install, operate, calibrate, and maintain a
calorimeter capable of continuously measuring, calculating, and
recording NHVvg at standard conditions.
(4) If the owner or operator uses a continuous net heating value
monitor according to paragraph (j)(3) of this section, the owner or
operator may, at
[[Page 141]]
their discretion, install, operate, calibrate, and maintain a monitoring
system capable of continuously measuring, calculating, and recording the
hydrogen concentration in the flare vent gas.
(5) Direct compositional or net heating value monitoring is not
required for purchased (``pipeline quality'') natural gas streams. The
net heating value of purchased natural gas streams may be determined
using annual or more frequent grab sampling at any one representative
location. Alternatively, the net heating value of any purchased natural
gas stream can be assumed to be 920 Btu/scf.
(6) Direct compositional or net heating value monitoring is not
required for gas streams that have been demonstrated to have consistent
composition (or a fixed minimum net heating value) according to the
methods in paragraphs (j)(6)(i) through (iii) of this section.
(i) The owner or operator shall submit to the Administrator a
written application for an exemption from monitoring. The application
must contain the following information:
(A) A description of the flare gas stream/system to be considered,
including submission of a portion of the appropriate piping diagrams
indicating the boundaries of the flare gas stream/system and the
affected flare(s) to be considered;
(B) A statement that there are no crossover or entry points to be
introduced into the flare gas stream/system (this should be shown in the
piping diagrams) prior to the point where the flow rate of the gas
streams is measured;
(C) An explanation of the conditions that ensure that the flare gas
net heating value is consistent and, if flare gas net heating value is
expected to vary (e.g., due to product loading of different material),
the conditions expected to produce the flare gas with the lowest net
heating value;
(D) The supporting test results from sampling the requested flare
gas stream/system for the net heating value. Sampling data must include,
at minimum, 2 weeks of daily measurement values (14 grab samples) for
frequently operated flare gas streams/systems; for infrequently operated
flare gas streams/systems, seven grab samples must be collected unless
other additional information would support reduced sampling. If the
flare gas stream composition can vary, samples must be taken during
those conditions expected to result in lowest net heating value
identified in paragraph (j)(6)(i)(C) of this section. The owner or
operator shall determine net heating value for the gas stream using
either gas composition analysis or net heating value monitor (with
optional hydrogen concentration analyzer) according to the method
provided in paragraph (l) of this section; and
(E) A description of how the 2 weeks (or seven samples for
infrequently operated flare gas streams/systems) of monitoring results
compares to the typical range of net heating values expected for the
flare gas stream/system going to the affected flare (e.g., ``the samples
are representative of typical operating conditions of the flare gas
stream going to the loading rack flare'' or ``the samples are
representative of conditions expected to yield the lowest net heating
value of the flare gas stream going to the loading rack flare'').
(F) The net heating value to be used for all flows of the flare vent
gas from the flare gas stream/system covered in the application. A
single net heating value must be assigned to the flare vent gas either
by selecting the lowest net heating value measured in the sampling
program or by determining the 95th percent confidence interval on the
mean value of all samples collected using the t-distribution statistic
(which is 1.943 for 7 grab samples or 1.771 for 14 grab samples).
(ii) The effective date of the exemption is the date of submission
of the information required in paragraph (j)(6)(i) of this section.
(iii) No further action is required unless refinery operating
conditions change in such a way that affects the exempt fuel gas stream/
system (e.g., the stream composition changes). If such a change occurs,
the owner or operator shall follow the procedures in paragraph
(j)(6)(iii)(A), (B), or (C) of this section.
[[Page 142]]
(A) If the operation change results in a flare vent gas net heating
value that is still within the range of net heating values included in
the original application, the owner or operator shall determine the net
heating value on a grab sample and record the results as proof that the
net heating value assigned to the vent gas stream in the original
application is still appropriate.
(B) If the operation change results in a flare vent gas net heating
value that is lower than the net heating value assigned to the vent gas
stream in the original application, the owner or operator may submit new
information following the procedures of paragraph (j)(6)(i) of this
section within 60 days (or within 30 days after the seventh grab sample
is tested for infrequently operated process units).
(C) If the operation change results in a flare vent gas net heating
value has greater variability in the flare gas stream/system such the
owner or operator chooses not to submit new information to support an
exemption, the owner or operator must begin monitoring the composition
or net heat content of the flare vent gas stream using the methods in
this section (i.e., grab samples every 8 hours until such time a
continuous monitor, if elected, is installed).
(k) Calculation methods for cumulative flow rates and determining
compliance with Vtip operating limits. The owner or operator shall
determine Vtip on a 15-minute block average basis according
to the following requirements.
(1) The owner or operator shall use design and engineering
principles to determine the unobstructed cross sectional area of the
flare tip. The unobstructed cross sectional area of the flare tip is the
total tip area that vent gas can pass through. This area does not
include any stability tabs, stability rings, and upper steam or air
tubes because flare vent gas does not exit through them.
(2) The owner or operator shall determine the cumulative volumetric
flow of flare vent gas for each 15-minute block average period using the
data from the continuous flow monitoring system required in paragraph
(i) of this section according to the following requirements, as
applicable. If desired, the cumulative flow rate for a 15-minute block
period only needs to include flow during those periods when regulated
material is sent to the flare, but owners or operators may elect to
calculate the cumulative flow rates across the entire 15-minute block
period for any 15-minute block period where there is regulated material
flow to the flare.
(i) Use set 15-minute time periods starting at 12 midnight to 12:15
a.m., 12:15 a.m. to 12:30 a.m. and so on concluding at 11:45 p.m. to
midnight when calculating 15-minute block average flow volumes.
(ii) If continuous pressure/temperature monitoring system(s) and
engineering calculations are used as allowed under paragraph (i)(4) of
this section, the owner or operator shall, at a minimum, determine the
15-minute block average temperature and pressure from the monitoring
system and use those values to perform the engineering calculations to
determine the cumulative flow over the 15-minute block average period.
Alternatively, the owner or operator may divide the 15-minute block
average period into equal duration subperiods(e.g., three 5-minute
periods) and determine the average temperature and pressure for each
subperiod, perform engineering calculations to determine the flow for
each subperiod, then add the volumetric flows for the subperiods to
determine the cumulative volumetric flow of vent gas for the 15-minute
block average period.
(3) The 15-minute block average Vtip shall be calculated
using the following equation.
[GRAPHIC] [TIFF OMITTED] TR01DE15.010
[[Page 143]]
Where:
Vtip = Flare tip velocity, feet per second.
Qcum = Cumulative volumetric flow over 15-minute block
average period, standard cubic feet.
Area = Unobstructed area of the flare tip, square feet.
900 = Conversion factor, seconds per 15-minute block average.
(4) If the owner or operator chooses to comply with paragraph (d)(2)
of this section, the owner or operator shall also determine the net
heating value of the flare vent gas following the requirements in
paragraphs (j) and (l) of this section and calculate Vmax
using the equation in paragraph (d)(2) of this section in order to
compare Vtip to Vmax on a 15-minute block average
basis.
(l) Calculation methods for determining flare vent gas net heating
value. The owner or operator shall determine the net heating value of
the flare vent gas (NHVvg) based on the composition
monitoring data on a 15-minute block average basis according to the
following requirements.
(1) If compositional analysis data are collected as provided in
paragraph (j)(1) or (2) of this section, the owner or operator shall
determine NHVvg of a specific sample by using the following
equation.
[GRAPHIC] [TIFF OMITTED] TR01DE15.011
Where:
NHVvg = Net heating value of flare vent gas, Btu/scf.
i = Individual component in flare vent gas.
n = Number of components in flare vent gas.
xi = Concentration of component i in flare vent gas, volume
fraction.
NHVi = Net heating value of component i according to table 12
of this subpart, Btu/scf. If the component is not specified in
table 12 of this subpart, the heats of combustion may be
determined using any published values where the net enthalpy
per mole of offgas is based on combustion at 25 [deg]C and 1
atmosphere (or constant pressure) with offgas water in the
gaseous state, but the standard temperature for determining
the volume corresponding to one mole of vent gas is 20 [deg]C.
(2) If direct net heating value monitoring data are collected as
provided in paragraph (j)(3) of this section but a hydrogen
concentration monitor is not used, the owner or operator shall use the
direct output of the monitoring system(s) (in Btu/scf) to determine the
NHVvg for the sample.
(3) If direct net heating value monitoring data are collected as
provided in paragraph (j)(3) of this section and hydrogen concentration
monitoring data are collected as provided in paragraph (j)(4) of this
section, the owner or operator shall use the following equation to
determine NHVvg for each sample measured via the net heating
value monitoring system.
NHVvg = NHVmeasured + 938xH2
Where:
NHVvg = Net heating value of flare vent gas, Btu/scf.
NHVmeasured = Net heating value of flare vent gas stream as
measured by the continuous net heating value monitoring
system, Btu/scf.
xH2 = Concentration of hydrogen in flare vent gas at the time the sample
was input into the net heating value monitoring system, volume
fraction.
938 = Net correction for the measured heating value of hydrogen (1,212 -
274), Btu/scf.
(4) Use set 15-minute time periods starting at 12 midnight to 12:15
a.m., 12:15 a.m. to 12:30 a.m. and so on concluding at 11:45 p.m. to
midnight when calculating 15-minute block averages.
(5) When a continuous monitoring system is used as provided in
paragraph (j)(1) or (3) of this section and, if applicable, paragraph
(j)(4) of this section, the owner or operator may elect to determine the
15-minute block average NHVvg using either the calculation
methods in paragraph (l)(5)(i) of this section or the calculation
methods in paragraph (l)(5)(ii) of this section. The owner or operator
may choose to comply using the calculation methods in paragraph
(l)(5)(i) of this section for
[[Page 144]]
some flares at the petroleum refinery and comply using the calculation
methods (l)(5)(ii) of this section for other flares. However, for each
flare, the owner or operator must elect one calculation method that will
apply at all times, and use that method for all continuously monitored
flare vent streams associated with that flare. If the owner or operator
intends to change the calculation method that applies to a flare, the
owner or operator must notify the Administrator 30 days in advance of
such a change.
(i) Feed-forward calculation method. When calculating
NHVvg for a specific 15-minute block:
(A) Use the results from the first sample collected during an event,
(for periodic flare vent gas flow events) for the first 15-minute block
associated with that event.
(B) If the results from the first sample collected during an event
(for periodic flare vent gas flow events) are not available until after
the second 15-minute block starts, use the results from the first sample
collected during an event for the second 15-minute block associated with
that event.
(C) For all other cases, use the results that are available from the
most recent sample prior to the 15-minute block period for that 15-
minute block period for all flare vent gas steams. For the purpose of
this requirement, use the time that the results become available rather
than the time the sample was collected. For example, if a sample is
collected at 12:25 a.m. and the analysis is completed at 12:38 a.m., the
results are available at 12:38 a.m. and these results would be used to
determine compliance during the 15-minute block period from 12:45 a.m.
to 1:00 a.m.
(ii) Direct calculation method. When calculating NHVvg
for a specific 15-minute block:
(A) If the results from the first sample collected during an event
(for periodic flare vent gas flow events) are not available until after
the second 15-minute block starts, use the results from the first sample
collected during an event for the first 15-minute block associated with
that event.
(B) For all other cases, use the arithmetic average of all
NHVvg measurement data results that become available during a
15-minute block to calculate the 15-minute block average for that
period. For the purpose of this requirement, use the time that the
results become available rather than the time the sample was collected.
For example, if a sample is collected at 12:25 a.m. and the analysis is
completed at 12:38 a.m., the results are available at 12:38 a.m. and
these results would be used to determine compliance during the 15-minute
block period from 12:30 a.m. to 12:45 a.m.
(6) When grab samples are used to determine flare vent gas
composition:
(i) Use the analytical results from the first grab sample collected
for an event for all 15-minute periods from the start of the event
through the 15-minute block prior to the 15-minute block in which a
subsequent grab sample is collected.
(ii) Use the results from subsequent grab sampling events for all 15
minute periods starting with the 15-minute block in which the sample was
collected and ending with the 15-minute block prior to the 15-minute
block in which the next grab sample is collected. For the purpose of
this requirement, use the time the sample was collected rather than the
time the analytical results become available.
(7) If the owner or operator monitors separate gas streams that
combine to comprise the total flare vent gas flow, the 15-minute block
average net heating value shall be determined separately for each
measurement location according to the methods in paragraphs (l)(1)
through (6) of this section and a flow-weighted average of the gas
stream net heating values shall be used to determine the 15-minute block
average net heating value of the cumulative flare vent gas.
(m) Calculation methods for determining combustion zone net heating
value. The owner or operator shall determine the net heating value of
the combustion zone gas (NHVcz) as specified in paragraph
(m)(1) or (2) of this section, as applicable.
(1) Except as specified in paragraph (m)(2) of this section,
determine the 15-minute block average NHVcz based on the 15-
minute block average vent gas and assist gas flow rates using the
following equation. For periods when
[[Page 145]]
there is no assist steam flow or premix assist air flow,
NHVcz = NHVvg.
[GRAPHIC] [TIFF OMITTED] TR01DE15.012
Where:
NHVcz = Net heating value of combustion zone gas, Btu/scf.
NHVvg = Net heating value of flare vent gas for the 15-minute
block period, Btu/scf.
Qvg = Cumulative volumetric flow of flare vent gas during the
15-minute block period, scf.
Qs = Cumulative volumetric flow of total steam during the 15-
minute block period, scf.
Qa,premix = Cumulative volumetric flow of premix assist air
during the 15-minute block period, scf.
(2) Owners or operators of flares that use the feed-forward
calculation methodology in paragraph (l)(5)(i) of this section and that
monitor gas composition or net heating value in a location
representative of the cumulative vent gas stream and that directly
monitor flare supplemental gas flow additions to the flare must
determine the 15-minute block average NHVcz using the
following equation.
[GRAPHIC] [TIFF OMITTED] TR01DE15.013
Where:
NHVcz = Net heating value of combustion zone gas, Btu/scf.
NHVvg = Net heating value of flare vent gas for the 15-minute
block period, Btu/scf.
Qvg = Cumulative volumetric flow of flare vent gas during the
15-minute block period, scf.
QNG2 = Cumulative volumetric flow of flare supplemental gas
during the 15-minute block period, scf.
QNG1 = Cumulative volumetric flow of flare supplemental gas
during the previous 15-minute block period, scf. For the first
15-minute block period of an event, use the volumetric flow
value for the current 15-minute block period, i.e.,
QNG1 = QNG2.
NHVNG = Net heating value of flare supplemental gas for the
15-minute block period determined according to the
requirements in paragraph (j)(5) of this section, Btu/scf.
Qs = Cumulative volumetric flow of total steam during the 15-
minute block period, scf.
Qa,premix = Cumulative volumetric flow of premix assist air
during the 15-minute block period, scf.
(n) Calculation methods for determining the net heating value
dilution parameter. The owner or operator shall determine the net
heating value dilution parameter (NHVdil) as specified in
paragraph (n)(1) or (2) of this section, as applicable.
(1) Except as specified in paragraph (n)(2) of this section,
determine the 15-minute block average NHVdil based on the 15-
minute block average vent gas and perimeter assist air flow rates using
the following equation only during periods when perimeter assist air is
used. For 15-minute block periods when there is no cumulative volumetric
flow of perimeter assist air, the 15-minute block average
NHVdil parameter does not need to be calculated.
[[Page 146]]
[GRAPHIC] [TIFF OMITTED] TR01DE15.014
Where:
NHVdil = Net heating value dilution parameter, Btu/ft\2\.
NHVvg = Net heating value of flare vent gas determined for
the 15-minute block period, Btu/scf.
Qvg = Cumulative volumetric flow of flare vent gas during the

flare that commenced construction on or after February 1, 2016.
(ii) The owner or operator must comply with the plan as submitted by
the date specified in paragraph (o)(2)(i) of this section. The plan
should be updated periodically to account for changes in the operation
of the flare, such as new connections to the flare or the installation
of a flare gas recovery system, but the plan need be re-submitted to the
Administrator only if the owner or operator alters the design smokeless
capacity of the flare. The owner or operator must comply with the
updated plan as submitted.

also be submitted to the following address: U.S. Environmental
Protection Agency, Office of Air Quality Planning and Standards, Sector
Policies and Programs Division, U.S. EPA Mailroom (E143-01), Attention:
Refinery Sector Lead, 109 T.W. Alexander Drive, Research Triangle Park,
NC 27711. Electronic copies in lieu of hard copies may also be submitted
to [email protected].
(3) The owner or operator of a flare subject to this subpart shall

flow event that contains regulated material and that meets either the
criteria in paragraph (o)(3)(i) or (ii) of this section.
(i) The vent gas flow rate exceeds the smokeless capacity of the
flare based on a 15-minute block average and visible emissions are
present from the flare for more than 5 minutes during any 2 consecutive
hours during the release event.
(ii) The vent gas flow rate exceeds the smokeless capacity of the
flare and the 15-minute block average flare tip velocity exceeds the
maximum flare tip velocity determined using the methods in paragraph
(d)(2) of this section.
(4) A root cause analysis and corrective action analysis must be
completed as soon as possible, but no later than 45 days after a flare
flow event meeting the criteria in paragraph (o)(3)(i) or (ii) of this
section. Special circumstances affecting the number of root cause
[[Page 149]]
analyses and/or corrective action analyses are provided in paragraphs
(o)(4)(i) through (v) of this section.
(i) You may conduct a single root cause analysis and corrective
action analysis for a single continuous flare flow event that meets both
of the criteria in paragraphs (o)(3)(i) and (ii) of this section.
(ii) You may conduct a single root cause analysis and corrective
action analysis for a single continuous flare flow event regardless of
the number of 15-minute block periods in which the flare tip velocity
was exceeded or the number of 2 hour periods that contain more the 5
minutes of visible emissions.
(iii) You may conduct a single root cause analysis and corrective
action analysis for a single event that causes two or more flares that
are operated in series (i.e., cascaded flare systems) to have a flow
event meeting the criteria in paragraph (o)(3)(i) or (ii) of this
section.
(iv) You may conduct a single root cause analysis and corrective
action analysis for a single event that causes two or more flares to
have a flow event meeting the criteria in paragraph (o)(3)(i) or (ii) of
this section, regardless of the configuration of the flares, if the root
cause is reasonably expected to be a force majeure event, as defined in
this subpart.
(v) Except as provided in paragraphs (o)(4)(iii) and (iv) of this
section, if more than one flare has a flow event that meets the criteria
in paragraph (o)(3)(i) or (ii) of this section during the same time
period, an initial root cause analysis shall be conducted separately for
each flare that has a flow event meeting the criteria in paragraph
(o)(3)(i) or (ii) of this section. If the initial root cause analysis
indicates that the flow events have the same root cause(s), the
initially separate root cause analyses may be recorded as a single root
cause analysis and a single corrective action analysis may be conducted.
(5) Each owner or operator of a flare required to conduct a root
cause analysis and corrective action analysis as specified in paragraphs
(o)(3) and (4) of this section shall implement the corrective action(s)
identified in the corrective action analysis in accordance with the
applicable requirements in paragraphs (o)(5)(i) through (iii) of this
section.
(i) All corrective action(s) must be implemented within 45 days of
the event for which the root cause and corrective action analyses were
required or as soon thereafter as practicable. If an owner or operator
concludes that no corrective action should be implemented, the owner or
operator shall record and explain the basis for that conclusion no later
than 45 days following the event.
(ii) For corrective actions that cannot be fully implemented within
45 days following the event for which the root cause and corrective
action analyses were required, the owner or operator shall develop an
implementation schedule to complete the corrective action(s) as soon as
practicable.
(iii) No later than 45 days following the event for which a root
cause and corrective action analyses were required, the owner or
operator shall record the corrective action(s) completed to date, and,
for action(s) not already completed, a schedule for implementation,

(6) The owner or operator shall determine the total number of events
for which a root cause and corrective action analyses was required
during the calendar year for each affected flare separately for events
meeting the criteria in paragraph (o)(3)(i) of this section and those
meeting the criteria in paragraph (o)(3)(ii) of this section. For the
purpose of this requirement, a single root cause analysis conducted for
an event that met both of the criteria in paragraphs (o)(3)(i) and (ii)
of this section would be counted as an event under each of the separate
criteria counts for that flare. Additionally, if a single root cause
analysis was conducted for an event that caused multiple flares to meet
the criteria in paragraph (o)(3)(i) or (ii) of this section, that event
would count as an event for each of the flares for each criteria in
paragraph (o)(3) of this section that was met during that event. The
owner or operator shall also determine the total number of events for
which a root cause and correct action analyses
[[Page 150]]
was required and the analyses concluded that the root cause was a force
majeure event, as defined in this subpart.
(7) The following events would be a violation of this emergency
flaring work practice standard.
(i) Any flow event for which a root cause analysis was required and
the root cause was determined to be operator error or poor maintenance.
(ii) Two visible emissions exceedance events meeting the criteria in
paragraph (o)(3)(i) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for the
same root cause for the same equipment.
(iii) Two flare tip velocity exceedance events meeting the criteria
in paragraph (o)(3)(ii) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for the
same root cause for the same equipment.
(iv) Three visible emissions exceedance events meeting the criteria
in paragraph (o)(3)(i) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for any
reason.
(v) Three flare tip velocity exceedance events meeting the criteria
in paragraph (o)(3)(ii) of this section that were not caused by a force
majeure event from a single flare in a 3 calendar year period for any
reason.

thereof) resulting in cessation of the emissions to which the monitoring
applies must not be included in the 15-minute block averages.
(3) Periods when the CPMS is out of control must not be included in
the 15-minute block averages.
(e) Additional requirements for gas chromatographs. For monitors
used to determine compositional analysis for net heating value per Sec.
63.670(j)(1), the gas chromatograph must also meet the requirements of
paragraphs (e)(1) through (3) of this section.
(1) The quality assurance requirements are in table 13 of this
subpart.
(2) The calibration gases must meet one of the following options:
(i) The owner or operator must use a calibration gas or multiple
gases that include all of compounds listed in paragraphs (e)(2)(i)(A)
through (K) of this section that may be reasonably expected to exist in
the flare gas stream and optionally include any of the compounds listed
in paragraphs (e)(2)(i)(L) through (O) of this section. All of the
calibration gases may be combined in one cylinder. If multiple
calibration gases are necessary to cover all compounds, the owner or
operator must calibrate the instrument on all of the gases.
(A) Hydrogen.
(B) Methane.
(C) Ethane.
(D) Ethylene.
(E) Propane.
(F) Propylene.
(G) n-Butane.
(H) iso-Butane.
(I) Butene (general). It is not necessary to separately speciate
butene
[[Page 155]]
isomers, but the net heating value of trans-butene must be used for co-
eluting butene isomers.
(J) 1,3-Butadiene. It is not necessary to separately speciate
butadiene isomers, but you must use the response factor and net heating
value of 1,3-butadiene for co-eluting butadiene isomers.
(K) n-Pentane. Use the response factor for n-pentane to quantify all
C5+ hydrocarbons.
(L) Acetylene (optional).
(M) Carbon monoxide (optional).
(N) Propadiene (optional).
(O) Hydrogen sulfide (optional).
(ii) The owner or operator must use a surrogate calibration gas
consisting of hydrogen and C1 through C5 normal hydrocarbons. All of the
calibration gases may be combined in one cylinder. If multiple
calibration gases are necessary to cover all compounds, the owner or
operator must calibrate the instrument on all of the gases.
(3) If the owner or operator chooses to use a surrogate calibration
gas under paragraph (e)(2)(ii) of this section, the owner or operator
must comply with paragraphs (e)(3)(i) and (ii) of this section.
(i) Use the response factor for the nearest normal hydrocarbon
(i.e., n-alkane) in the calibration mixture to quantify unknown
components detected in the analysis.
(ii) Use the response factor for n-pentane to quantify unknown
components detected in the analysis that elute after n-pentane.

each operation specified in paragraphs (a)(2)(i) through (a)(2)(vi) of
this section that is located at the plant site, the affected source is
the entire group of off-site material management units associated with
the operation. An off-site material management unit is a tank,
container, surface impoundment, oil-water separator, organic-water
separator, or transfer system used to manage off-site material. For the
purpose of implementing the standards under this subpart, a unit that
meets the definition of a tank or container but also is equipped with a
vent that serves as a process vent for any of the processes listed in
paragraphs (c)(2)(i) through (c)(2)(vi) of this section is not an off-
site material management unit but instead is a process vent and is to be
included in the appropriate affected source group under paragraph (c)(2)
of this section. Examples of such a unit may include, but are not
limited to, a distillate receiver vessel, a primary condenser, a bottoms
receiver vessel, a surge control tank, a separator tank, and a hot well.
(2) Process vents. For each operation specified in paragraphs
(a)(2)(i) through (a)(2)(vi) of this section that is located

recovery of off-site material. Distillation means a process, either
batch or continuous, separating one or more off-site material feed
streams into two or more exit streams having different component
concentrations from those in the feed stream or streams. The separation
is achieved by the redistribution of the components between the liquid
and vapor phases as they approach equilibrium within the distillation
unit.
(ii) Fractionation process used for the treatment, recycling, or
recovery of off-site material. Fractionation means a liquid mixture
separation process or method used to separate a mixture of several
volatile components of different boiling points in successive stages,
each stage removing from the mixture some proportion of one of the
components.
(iii) Thin-film evaporation process used for the treatment,
recycling, or recovery of off-site material. Thin-film evaporation means
a liquid mixture separation process or method that uses a heating
surface consisting of a large diameter tube that may be either straight
or tapered, horizontal or vertical. Liquid is spread on the tube wall by
a rotating assembly of blades that maintain a close clearance from the
wall or actually ride on the film of liquid on the wall.
(iv) Solvent extraction process used for the treatment, recycling,
or recovery of off-site material. Solvent extraction means a separation
process or method in which a solid or a solution is contacted with a
liquid solvent (the material and the solvent being relatively insoluble
in each other) to preferentially dissolve and transfer one or more
components into the solvent.
(v) Steam stripping process used for the treatment, recycling, or
recovery of off-site material. Steam stripping means a liquid mixture
separation process or method in which vaporization of the volatile
components of a liquid mixture occurs by the introduction of steam
directly into the process.
(vi) Gas stripping process used for the treatment, recycling, or
recovery of off-site material. Gas stripping means a desorption process
or method used to transfer one or more volatile components from a liquid
mixture into a gas stream either with or without the application of heat
to the liquid. Packed towers, spray towers, and bubble-cap, sieve, or
valve-type plate towers are examples of the process configurations used
for contacting the gas and a liquid.
(3) Equipment leaks. For each operation specified in paragraphs
(a)(2)(i) through (a)(2)(vi) of this section that is located at the
plant site, the affected source is the entire group of equipment
components for which each component meets all of the conditions
specified in paragraphs (c)(3)(i) through (c)(3)(iii) of this section.
If any one of these conditions do not apply to an equipment component,
then that component is not part of the affected source for equipment
leaks.
(i) The equipment component is a pump, compressor, agitator,
pressure relief device, sampling connection system, open-ended valve or
line, valve, connector, or instrumentation system;
(ii) The equipment component contains or contacts off-site material
having a total HAP concentration equal to or greater than 10 percent by
weight; and
(iii) The equipment component is intended to operate for 300 hours
or more during a calendar year in off-site material service, as defined
in Sec. 63.681 of this subpart.
(d) Facility-wide exemption. The owner or operator of affected
sources subject to this subpart is exempted from the requirements of
Sec. Sec. 63.682 through 63.699 of this subpart in situations when the
total annual quantity of the HAP that is contained in the off-site
material received at the plant site is less than 1 megagram per year.
For a plant site to be exempted under the provisions of this paragraph
(d), the owner or operator must meet the requirements in paragraphs
(d)(1) through (d)(3) of this section.
(1) The owner or operator must prepare an initial determination of
the
[[Page 169]]
total annual HAP quantity in the off-site material received at the plant
site. This determination is based on the total quantity of the HAP
listed in Table 1 of this subpart as determined at the point-of-delivery
for each off-site material stream.
(2) The owner or operator must prepare a new determination whenever
the extent of changes to the quantity or composition of the off-site
material received at the plant site could cause the total annual HAP
quantity in the off-site material received at the plant site to exceed
the limit of 1 megagram per year.
(3) The owner or operator must maintain documentation to support the
owner's or operator's determination of the total annual HAP quantity in
the off-site material received at the plant site. This documentation
must include the basis and data used for determining the HAP content of
the off-site material.

valve or line, valve, connector, or instrumentation system contains or
contacts off-site material.
Off-site material stream means an off-site material produced or
generated by a particular process or source such that the composition
and form of the material comprising the stream remain consistent. An
off-site material stream may be delivered, transferred, or otherwise
moved to the plant site in a continuous flow of material (e.g.,
wastewater flowing through a pipeline) or in a series of discrete
batches of material (e.g., a truckload of drums all containing the same
off-site material or multiple bulk truck loads of an off-site material
produced by the same process).
Oil-water separator means a separator as defined for this subpart
that is used to separate oil from water.
Operating parameter value means a minimum or maximum value
established for a control device or treatment process parameter which,
if achieved by itself or in combination with one or more other operating
parameter values, determines that an owner or operator has complied with
an applicable emission limitation or standard.
Organic-water separator means a separator as defined for this
subpart that is used to separate organics from water.
Plant site means all contiguous or adjoining property that is under
common control including properties that are separated only by a road or
other public right-of-way. Common control includes properties that are
owned, leased, or operated by the same entity, parent entity,
subsidiary, or any combination thereof. A unit or group of units within
a contiguous property that are not under common control (e.g., a
wastewater treatment unit or solvent recovery unit located at the site
but is sold to a different company) is a different plant site.
Point-of-delivery means the point at the boundary or within the
plant site
[[Page 173]]
where the owner or operator first accepts custody, takes possession, or
assumes responsibility for the management of an off-site material stream
managed in a waste management operation or recovery operation specified
in Sec. 63.680 (a)(2)(i) through (a)(2)(vi) of this subpart. The
characteristics of an off-site material stream are determined prior to
combining the off-site material stream with other off-site material
streams or with any other materials.
Point-of-treatment means a point after the treated material exits
the treatment process but before the first point downstream of the
treatment process exit where the organic constituents in the treated
material have the potential to volatilize and be released to the
atmosphere. For the purpose of applying this definition to this subpart,
the first point downstream of the treatment process exit is not a
fugitive emission point due to an equipment leak from any of the
following equipment components: Pumps, compressors, valves, connectors,
instrumentation systems, or pressure relief devices.
Pressure release means the emission of materials resulting from the
system pressure being greater than the set pressure of the pressure
relief device. This release can be one release or a series of releases
over a short time period.
Pressure relief device or valve means a safety device used to
prevent operating pressures from exceeding the maximum allowable working
pressure of the process equipment. A common pressure relief device is a
spring-loaded pressure relief valve. Devices that are actuated either by
a pressure of less than or equal to 2.5 pounds per square inch gauge or
by a vacuum are not pressure relief devices.

heat released by burning fuel directly to process streams or to heat
transfer liquids other than water.
Process vent means an open-ended pipe, stack, or duct through which
a gas stream containing HAP is continuously or intermittently discharged
to the atmosphere from any of the processes listed in Sec.
63.680(c)(2)(i) through (vi). For the purpose of this subpart, a process
vent is none of the following: a pressure relief device; an open-ended
line or other vent that is subject to the equipment leak control
requirements under Sec. 63.691; or a stack or other vent that is used
to exhaust combustion products from a boiler, furnace, process heater,
incinerator, or other combustion device.
Recovery operation means the collection of off-site material
management units, process vents, and equipment components used at a
plant site to manage an off-site material stream from the point-of-
delivery through the point where the material has been recycled,
reprocessed, or re-refined to obtain the intended product or to remove
the physical and chemical impurities of concern.
Separator means a waste management unit, generally a tank, used to
separate oil or organics from water. A separator consists of not only
the separation unit but also the forebay and other separator basins,
skimmers, weirs, grit chambers, sludge hoppers, and bar screens that are
located directly after the individual drain system and prior to any
additional treatment units such as an air flotation unit clarifier or
biological treatment unit. Examples of a separator include, but are not
limited to, an API separator, parallel-plate interceptor, and
corrugated-plate interceptor with the associated ancillary equipment.
Single-seal system means a floating roof having one continuous seal.
This seal may be vapor-mounted, liquid-mounted, or a metallic shoe seal.
Surface impoundment means a unit that is a natural topographical
depression, man-made excavation, or diked area formed primarily of
earthen materials (although it may be lined with man-made materials),
which is designed to hold an accumulation of liquids. Examples of
surface impoundments include holding, storage, settling, and aeration
pits, ponds, and lagoons.
Tank means a stationary unit that is constructed primarily of
nonearthen materials (such as wood, concrete, steel, fiberglass, or
plastic) which provide structural support and is designed to hold an
accumulation of liquids or other materials.
[[Page 174]]
Transfer system means a stationary system for which the predominant
function is to convey liquids or solid materials from one point to
another point within a waste management operation or recovery operation.
For the purpose of this subpart, the conveyance of material using a
container (as defined for this subpart) or a self-propelled vehicle
(e.g., a front-end loader) is not a transfer system. Examples of a
transfer system include but are not limited to a pipeline, an individual
drain system, a gravity-operated conveyor (such as a chute), and a
mechanically-powered conveyor (such as a belt or screw conveyor).
Temperature monitoring device means a piece of equipment used to
monitor temperature and having an accuracy of 1
percent of the temperature being monitored expressed in degrees Celsius
([deg]C) or 1.2 degrees [deg]C, whichever value is
greater.
Treatment process means a process in which an off-site material
stream is physically, chemically, thermally, or biologically treated to
destroy, degrade, or remove hazardous air pollutants contained in the
off-site material. A treatment process can be composed of a single unit
(e.g., a steam stripper) or a series of units (e.g., a wastewater
treatment system). A treatment process can be used to treat one or more
off-site material streams at the same time.
Used oil means any oil refined from crude oil or any synthetic oil
that has been used and as a result of such use is contaminated by
physical or chemical impurities. This definition is the same definition
of ``used oil'' in 40 CFR 279.1.
Used solvent means a mixture of aliphatic hydrocarbons or a mixture
of one and two ring aromatic hydrocarbons that has been used as a
solvent and as a result of such use is contaminated by physical or
chemical impurities.
Vapor-mounted seal means a continuous seal that is mounted such that
there is a vapor space between the liquid in the unit and the bottom of
the seal.
Volatile organic hazardous air pollutant concentration or VOHAP
concentration means the fraction by weight of those compounds listed in
Table 1 of this subpart that are in an off-site material as measured
using Method 305 in appendix A of this part and expressed in terms of
parts per million (ppm). As an alternative to using Method 305, an owner
or operator may determine the HAP concentration of an off-site material
using any one of the other test methods specified in Sec.
63.694(b)(2)(ii) of this subpart. When a test method specified in Sec.
63.694(b)(2)(ii) of this subpart other than Method 305 is used to
determine the speciated HAP concentration of an off-site material, the
individual compound concentration may be adjusted by the corresponding
fm305 value listed in Table 1 of this subpart to determine a
VOHAP concentration.
Waste means a material generated from industrial, commercial,
mining, or agricultural operations or from community activities that is
discarded, discharged, or is being accumulated, stored, or physically,
chemically, thermally, or biologically treated prior to being discarded
or discharged.
Waste management operation means the collection of off-site material
management units, process vents, and equipment components used at a
plant site to manage an off-site material stream from the point-of-
delivery to the point where the waste exits or is discharged from the
plant site or the waste is placed for on-site disposal in a unit not
subject to this subpart (e.g., a waste incinerator, a land disposal
unit).
Waste stabilization process means any physical or chemical process
used to either reduce the mobility of hazardous constituents in a waste
or eliminate free liquids as determined by Test Method 9095--Paint
Filter Liquids Test in ``Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods,'' EPA Publication No. SW-846, Third Edition,
September 1986, as amended by Update I, November 15, 1992. (As an
alternative, an owner or operator may use any more recent, updated
version of Method 9095 approved by the EPA.) A waste stabilization
process includes mixing the waste with binders or other materials and
curing the resulting waste and binder mixture. Other synonymous terms
used to refer to this process are ``waste fixation'' or ``waste
solidification.'' A waste stabilization
[[Page 175]]
process does not include the adding of absorbent materials to the
surface of a waste, without mixing, agitation, or subsequent curing, to
absorb free liquid.

material in the off-site material management unit that the average VOHAP
concentration of the off-site material is less than 500 parts per
million by weight (ppmw) at the point-of-delivery. The owner or operator
must perform an initial determination of the average VOHAP concentration
of the off-site material using the procedures specified in Sec.
63.694(b) of this subpart. This initial determination must be performed
either before the first time any portion of the off-site material stream
is placed in the unit or by the compliance date, whichever date is
later. Thereafter, the owner or operator must review and update, as
necessary, this determination at least once every calendar year
following the date of the initial determination for the off-site
material stream.
(2) An off-site material management unit is exempted from the
requirements in paragraph (b)(1) of this section when the owner or
operator meets one of the exemptions provided in paragraphs (b)(2)(i)

Sec. 63.694(h) of this subpart. The written procedure must list the
operating parameters that will be monitored and state the frequency of
monitoring to ensure that the biological treatment unit is operating
between the minimum operating parameter values and maximum operating
parameter values to establish that the biological treatment unit is
continuously achieving the performance requirement.
(f) The owner or operator must maintain records for each treatment
process in accordance with the requirements of Sec. 63.696(a) of this
subpart.
(g) The owner or operator must prepare and submit reports for each
treatment process in accordance with the requirements of Sec. 63.697(a)
of this subpart.
(h) The Administrator may at any time conduct or require that the
owner or operator conduct testing necessary to demonstrate that a
treatment process is achieving the applicable performance requirements

and this program must include the following elements related to
measuring the concentrations of volatile compounds:
(1) Documentation of site-specific procedures to minimize the loss

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

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

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

(h)(1) of this section.
(i) Determination of actual HAP mass removal rate
(MRbio). (1) The actual HAP mass removal rate
(MRbio) shall be determined based on results for a minimum of
three consecutive runs. The sampling time for each run shall be at least
1 hour.
(2) The HAP mass flow entering the process (Eb) shall be
determined using the test methods and procedures specified in paragraphs

(j) Determination of maximum HAP vapor pressure for off-site
material in a tank. (1) The maximum HAP vapor pressure of the off-site
material composition managed in a tank shall be determined using either
direct measurement as specified in paragraph (j)(2) of this section or
by knowledge of the off-site material as specified by paragraph (j)(3)
of this section.
(2) Direct measurement to determine the maximum HAP vapor pressure
of an off-site material.
(i) Sampling. A sufficient number of samples shall be collected to
be representative of the off-site material contained in the tank. All
samples shall be collected and handled in accordance with written
procedures prepared by the owner or operator and documented in a site
sampling plan. This plan shall describe the procedure by which
representative samples of the off-site material is collected such that a
minimum loss of organics occurs throughout the sample collection and
handling process and by which sample integrity is maintained. A copy of
the written sampling plan shall be maintained on-site in the plant site
operating records. An example of an acceptable sampling plan includes a
plan incorporating sample collection and handling procedures in
accordance with the requirements specified in ``Test Methods for
Evaluating Solid Waste, Physical/Chemical Methods,'' EPA Publication No.
SW-846 or Method 25D in 40 CFR part 60, appendix A.
(ii) Analysis. Any one of the following methods may be used to
analyze the samples and compute the maximum HAP vapor pressure of the
off-site material:
(A) Method 25E in 40 CFR part 60 appendix A;
(B) Methods described in American Petroleum Institute Bulletin 2517,
``Evaporation Loss from External Floating Roof Tanks,'';
(C) Methods obtained from standard reference texts;
(D) ASTM Method 2879-83; or
(E) Any other method approved by the Administrator.
(3) Use of knowledge to determine the maximum HAP vapor pressure of
the off-site material. Documentation shall be prepared and recorded that
presents the information used as the basis for the owner's or operator's
knowledge that the maximum HAP vapor pressure of the off-site material
is less than the maximum vapor pressure limit listed in Table 3, Table
4, or Table 5 of this subpart for the applicable tank design capacity
category. Examples of information that may be used include: the off-site
material is generated by a process for which at other locations it
previously has been determined by direct measurement that the off-site
material maximum HAP vapor pressure is less than the maximum vapor
pressure limit for the appropriate tank design capacity category. In the
event that the Administrator and the owner or operator disagree on a
determination of the maximum HAP vapor pressure for an off-site material
stream using knowledge, then the results from a determination of HAP
vapor pressure using direct measurement as specified in paragraph (j)(2)
of this section shall be used to establish compliance with the
applicable requirements of this subpart. The Administrator may perform
or require that the owner or operator perform this determination using
direct measurement.
(k) Procedure for determining no detectable organic emissions for
the purpose of complying with this subpart.
(1) The test shall be conducted in accordance with the procedures
specified in Method 21 of 40 CFR part 60, appendix A. Each potential
leak interface (i.e., a location where organic vapor leakage could
occur) on the cover and associated closure devices shall be checked.
Potential leak interfaces that are associated with covers and closure
devices include, but are not limited to: the interface of the cover and
its foundation mounting; the periphery of any opening on the cover and
its associated closure device; and the sealing seat interface on a
spring-loaded pressure-relief valve.
[[Page 206]]
(2) The test shall be performed when the unit contains a material
having a total organic concentration representative of the range of
concentrations for the materials expected to be managed in the unit.
During the test, the cover and closure devices shall be secured in the
closed position.
(3) The detection instrument shall meet the performance criteria of
Method 21 of 40 CFR part 60, appendix A, except the instrument response
factor criteria in section 8.1.1 of Method 21 shall be for the weighted
average composition of the organic constituents in the material placed
in the unit at the time of monitoring, not for each individual organic
constituent.
(4) The detection instrument shall be calibrated before use on each
day of its use by the procedures specified in Method 21 of 40 CFR part
60, appendix A.
(5) Calibration gases shall be as follows:
(i) Zero air (less than 10 ppmv hydrocarbon in air); and
(ii) A mixture of methane or n-hexane in air at a concentration of
approximately, but less than, 10,000 ppmv.
(6) An owner or operator may choose to adjust or not adjust the
detection instrument readings to account for the background organic
concentration level. If an owner or operator chooses to adjust the
instrument readings for the background level, the background level value
must be determined according to the procedures in Method 21 of 40 CFR
part 60, appendix A.
(7) Each potential leak interface shall be checked by traversing the
instrument probe around the potential leak interface as close to the
interface as possible, as described in Method 21. In the case when the
configuration of the cover or closure device prevents a complete
traverse of the interface, all accessible portions of the interface
shall be sampled. In the case when the configuration of the closure
device prevents any sampling at the interface and the device is equipped
with an enclosed extension or horn (e.g., some pressure relief devices),
the instrument probe inlet shall be placed at approximately the center
of the exhaust area to the atmosphere.
(8) An owner or operator must determine if a potential leak
interface operates with no detectable emissions using the applicable
procedure specified in paragraph (k)(8)(i) or (k)(8)(ii) of this
section.
(i) If an owner or operator chooses not to adjust the detection
instrument readings for the background organic concentration level, then
the maximum organic concentration value measured by the detection
instrument is compared directly to the applicable value for the
potential leak interface as specified in paragraph (k)(9) of this
section.
(ii) If an owner or operator chooses to adjust the detection
instrument readings for the background organic concentration level, the
value of the arithmetic difference between the maximum organic
concentration value measured by the instrument and the background
organic concentration value as determined in paragraph (k)(6) of this
section is compared with the applicable value for the potential leak
interface as specified in paragraph (k)(9) of this section.
(9) A potential leak interface is determined to operate with no
detectable emissions using the applicable criteria specified in
paragraphs (k)(9)(i) and (k)(9)(ii) of this section.
(i) For a potential leak interface other than a seal around a shaft
that passes through a cover opening, the potential leak interface is
determined to operate with no detectable organic emissions if the
organic concentration value determined in paragraph (k)(8) is less than
500 ppmv.
(ii) For a seal around a shaft that passes through a cover opening,
the potential leak interface is determined to operate with no detectable
organic emissions if the organic concentration value determined in
paragraph (k)(8) is less than 10,000 ppmv.
(l) Control device performance test procedures. Performance tests
shall be based on representative performance (i.e., performance based on
normal operating conditions) and shall exclude periods of startup and
shutdown unless specified by the Administrator. The owner or operator
may not conduct performance tests during periods of malfunction. The
owner or operator
[[Page 207]]
must record the process information that is necessary to document
operating conditions during the test and include in such record an
explanation to support that such conditions represent normal operation.
Upon request, the owner or operator shall make available to the
Administrator such records as may be necessary to determine the
conditions of performance tests.
(1) Method 1 or 1A of 40 CFR part 60, appendix A, as appropriate,
shall be used for selection of the sampling sites at the inlet and

the final product recovery device.
(B) If a vent stream is introduced with the combustion air or as an
auxiliary fuel into a boiler or process heater, the location of the
inlet sampling sites shall be selected to ensure that the measurement of

all vent streams and primary and secondary fuels introduced into the
boiler or process heater.
(ii) To determine compliance with an enclosed combustion device
concentration limit, the sampling site shall be located at the outlet of

be used to measure methane and ethane, and the measured concentration
may be subtracted from the Method 25A measurement. Alternatively, any
other method or data that has been validated according to the applicable
procedures in Method 301 in appendix A of this part may be used. The
following procedures shall be used to calculate percent reduction
efficiency:

(B) When the TOC mass rate is calculated, the average concentration
reading (minus methane and ethane) measured by Method 25A of 40 CFR part
60, appendix A shall be used in the equation in paragraph (l)(3)(ii)(A)
of this section.
(C) When the total HAP mass rate is calculated, only the HAP
constituents shall be summed using the equation in paragraph
(l)(3)(ii)(A) of this section.
[[Page 208]]

introduced with the combustion air or as a secondary fuel, the weight-
percent reduction of total HAP or TOC (minus methane and ethane) across
the device shall be determined by comparing the TOC (minus methane and
ethane) or total HAP in all combusted vent streams and primary and
secondary fuels with the TOC (minus methane and ethane) or total HAP
exiting the device, respectively.
(4) To determine compliance with the enclosed combustion device
total HAP concentration limit of this subpart, the owner or operator
shall use Method 18 of 40 CFR part 60, appendix A to measure the total
HAP in Table 1 of this subpart or Method 25A of 40 CFR part 60, appendix
A to measure TOC. Method 18 may be used to measure methane and ethane
and the measured concentration may be subtracted from the Method 25A
measurement. Alternatively, any other method or data that has been
validated according to Method 301 in appendix A of this part, may be
used. The following procedures shall be used to calculate parts per
million by volume concentration, corrected to 3 percent oxygen:
(i) A minimum of three sample runs must be performed. The minimum
sampling time for each run shall be 1 hour. For Method 18, either an
integrated sample or a minimum of four grab samples shall be taken. If

The samples shall be collected during the
[[Page 209]]
same time that the samples are collected for determining TOC
concentration or total HAP concentration.
(B) The concentration corrected to 3 percent oxygen (Cc)

the total HAP concentration. Alternatively, any other method or data
that has been validated according to the protocol in Method 301 of
appendix A of this part may be used.
(ii) Where Method 18 of 40 CFR part 60, appendix A, is used, the
following procedures must be used to calculate parts per million by

(5)(i) Except for periods of monitoring system malfunctions, repairs
associated with monitoring system malfunctions and required monitoring
system quality assurance or quality control activities (including, as
applicable, calibration checks and required zero and span adjustments),
the owner or operator must operate the continuous monitoring system at
all times the affected source is operating. A monitoring system
malfunction is any sudden, infrequent, not reasonably preventable
failure of the monitoring system to provide data. Monitoring system
failures that are caused in part by poor maintenance or careless
operation are not malfunctions. The owner or operator is required to
complete monitoring system repairs in response to monitoring system
malfunctions and to return the monitoring system to operation as
expeditiously as practicable.
(ii) The owner or operator may not use data recorded during
monitoring system malfunctions, repairs associated with monitoring
system malfunctions, or required monitoring system quality assurance or
control activities in calculations used to report emissions or operating
levels. The owner or operator must use all the data collected during all
other required data collection periods in assessing the operation of the
control device and associated control system. The owner or operator must
report any periods for which the monitoring system failed to collect
required data.

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

the seal and multiplying each such width by its respective
circumferential distance.
(4) The total gap area shall be calculated by adding the gap surface
areas determined for each identified gap location for the primary seal
and the secondary seal individually, and then dividing the sum for each
seal type by the nominal diameter of the tank. These total gap areas for
the primary seal and secondary seal are then compared to the respective
standards for the seal type as specified in Sec. 63.685(f)(1) of this
subpart.
(E) In the event that the seal gap measurements do not conform to
the specifications in Sec. 63.685(f)(1) of this subpart, the owner or

inspected by the
[[Page 212]]
owner or operator to check for defects that could result in air
emissions. Defects include, but are not limited to, visible cracks,
holes, or gaps in the roof sections or between the roof and the
separator wall; broken, cracked, or otherwise damaged seals or gaskets
on closure devices; and broken or missing hatches, access covers, caps,
or other closure devices. In the case when a tank is buried partially or
entirely underground, inspection is required only for those portions of
the cover that extend to or above the ground surface, and those
connections that are on such portions of the cover (e.g., fill ports,
access hatches, gauge wells, etc.) and can be opened to the atmosphere.
(ii) The owner or operator must perform an initial inspection

the defect the next time the process or unit that vents to the closed-
vent system is shutdown. Repair of the defect must be completed before
the process or unit resumes operation.
(A) Completion of the repair is technically infeasible without the
shutdown of the process or unit that vents to the closed-vent system.
(B) The owner or operator determines that the air emissions
resulting from the repair of the defect within the specified period
would be greater than the fugitive emissions likely to result by
delaying the repair until the next time the process or unit that vents
to the closed-vent system is shutdown.
(iii) The owner or operator shall maintain a record of the defect
repair in accordance with the requirements specified in Sec. 63.696 of
this subpart.
(d) Owners and operators that use a transfer system equipped with a

emissions. Defects include, but are not limited to, visible cracks,
holes, or gaps in the cover sections or between the cover and its
mounting; broken, cracked, or otherwise damaged seals or gaskets on
closure devices; and broken or missing hatches, access covers, caps, or
other closure devices. In the case when a transfer system is buried
partially or entirely underground, inspection is required only for those
portions of the cover that extend to or above the ground surface, and
those connections that are on such portions of the cover (e.g., access
hatches, etc.) and can be opened to the atmosphere.
(2) The owner or operator must perform an initial inspection
following installation of the cover. Thereafter, the owner or operator
must perform the inspections at least once every calendar year except as

subpart.
(5) The owner or operator shall repair all detected defects as
follows:
(i) The owner or operator shall make first efforts at repair of the
defect no later than 5 calendar days after detection and repair shall be
completed as soon as possible but no later than 45 calendar days after
detection except as provided in paragraph (d)(5)(ii) of this section.
(ii) Repair of a defect may be delayed beyond 45 calendar days if
the owner or operator determines that repair of the defect requires
emptying or temporary removal from service of the transfer system and no
alternative transfer system is available at the site to accept the
material normally handled by the system. In this case, the owner or
operator shall repair the defect the next time the process or unit that
is generating the material handled by the transfer system stops
operation. Repair of the defect must be completed before the process or
unit resumes operation.
(iii) The owner or operator shall maintain a record of the defect
repair in accordance with the requirements specified in Sec. 63.696 of
this subpart.
(e) Control device monitoring requirements. For each control device
required under Sec. 63.693 to be monitored in accordance with the
provisions of this paragraph (e), the owner or operator must ensure that
each control device operates properly by monitoring the control device
in accordance with the requirements specified in paragraphs (e)(1)
through (5) of this section.
(1) A continuous parameter monitoring system must be used to measure
the operating parameter or parameters specified for the control device
in Sec. 63.693(d) through Sec. 63.693(g) of this subpart as applicable
to the type and design of the control device. The continuous parameter
monitoring system must meet the following specifications and
requirements:
(i) The continuous parameter monitoring system must measure either
an instantaneous value at least once every 15 minutes or an average
value for intervals of 15 minutes or less and continuously record
either:
(A) Each measured data value; or
(B) Each block average value for each 1-hour period or shorter
periods calculated from all measured data values during each period. If
values are measured more frequently than once per minute, a single value
for each minute may be used to calculate the hourly (or shorter period)
block average instead of all measured values.
(ii) The monitoring system must be installed, calibrated, operated,
and maintained in accordance with the manufacturer's specifications or
other written procedures that provide reasonable assurance that the
monitoring equipment is operating properly.
(2) Using the data recorded by the monitoring system, the owner or
operator must calculate the daily average value for each monitored
operating parameter for each operating day. If operation of the control
device is continuous, the operating day is a 24-hour period. If control
device operation is not continuous, the operating day is the total
number of hours of control device operation per 24-hour period. Valid
data points must be available for 75 percent of the operating hours in
an operating day to compute the daily average.
(3) For each monitored operating parameter, the owner or operator
must establish a minimum operating parameter value or a maximum
operating parameter value, as appropriate, to define the range of
conditions at which the control device must be operated to continuously
achieve the applicable performance requirements specified in Sec.
63.693(b)(2) of this subpart. Each minimum or maximum operating
parameter value must be established in accordance with the requirements
in paragraphs (e)(3)(i) and (e)(3)(ii) of this section.
(i) If the owner or operator conducts a performance test to
demonstrate control device performance, then the minimum or maximum
operating parameter value must be established based on values measured
during the performance test and supplemented, as necessary, by the
control device design specifications, manufacturer recommendations, or
other applicable information.
[[Page 215]]
(ii) If the owner or operator uses a control device design analysis
to demonstrate control device performance, then the minimum or maximum
operating parameter value must be established based on the control
device design analysis and supplemented, as necessary, by the control
device manufacturer recommendations or other applicable information.
(4) A deviation for a given control device is determined to have
occurred when the monitoring data or lack of monitoring data result in
any one of the criteria specified in paragraphs (e)(4)(i) through (iii)
of this section being met. When multiple operating parameters are
monitored for the same control device and during the same operating day
more than one of these operating parameters meets a deviation criterion
specified in paragraphs (e)(4)(i) through (iii) of this section, then a
single deviation is determined to have occurred for the control device
for that operating day.
(i) A deviation occurs when the daily average value of a monitored
operating parameter is less than the minimum operating parameter limit
(or, if applicable, greater than the maximum operating parameter limit)
established for the operating parameter in accordance with the
requirements of paragraph (e)(3) of this section.
(ii) A deviation occurs when the period of control device operation
is 4 hours or greater in an operating day and the monitoring data are
insufficient to constitute a valid hour of data for at least 75 percent
of the operating hours. Monitoring data are insufficient to constitute a
valid hour of data if measured values are unavailable for any of the 15-
minute periods within the hour.
(iii) A deviation occurs when the period of control device operation
is less than 4 hours in an operating day and more than 1 of the hours
during the period does not constitute a valid hour of data due to
insufficient monitoring data. Monitoring data are insufficient to
constitute a valid hour of data if measured values are unavailable for
any of the 15-minute periods within the hour.
(5) For each deviation, except when the deviation occurs during
periods of non-operation of the unit or the process that is vented to
the control device (resulting in cessation of HAP emissions to which the
monitoring applies), the owner or operator shall be deemed to have
failed to have applied control in a manner that achieves the required
operating parameter limits. Failure to achieve the required operating
parameter limits is a violation of this standard.
(f) Alternative inspection and monitoring interval. Following the
initial inspection and monitoring of a piece of air pollution control
equipment in accordance with the applicable provisions of this section,
subsequent inspection and monitoring of the equipment may be performed
at intervals longer than 1 year when an owner or operator determines
that performing the required inspection or monitoring procedures would
expose a worker to dangerous, hazardous, or otherwise unsafe conditions
and the owner or operator complies with the requirements specified in
paragraphs (f)(1) and (f)(2) of this section.
(1) The owner or operator must prepare and maintain at the plant
site written documentation identifying the specific air pollution
control equipment designated as ``unsafe to inspect and monitor.'' The
documentation must include for each piece of air pollution control
equipment designated as such a written explanation of the reasons why
the equipment is unsafe to inspect or monitor using the applicable
procedures under this section.
(2) The owner or operator must develop and implement a written plan
and schedule to inspect and monitor the air pollution control equipment
using the applicable procedures specified in this section during times
when a worker can safely access the air pollution control equipment. The
required inspections and monitoring must be performed as frequently as
practicable but do not need to be performed more frequently than the
periodic schedule that would be otherwise applicable to the air
pollution control equipment under the provisions of this section. A
[[Page 216]]
copy of the written plan and schedule must be maintained at the plant
site.

Subpart EE_National Emission Standards for Magnetic Tape Manufacturing
Operations
Source: 59 FR 64596, Dec. 15, 1994, unless otherwise noted.
Sec. 63.701 Applicability.
(a) Except as specified in paragraph (b) of this section, the
provisions of this subpart apply to:
(1) Each new and existing magnetic tape manufacturing operation
located at a major source of hazardous air pollutant (HAP) emissions;
and
(2) A magnetic tape manufacturing operation for which the owner or
operator chooses to use the provisions of Sec. 63.703(b) and (h) to
obtain a Federally enforceable limit on its potential to emit HAP.
Explanatory Note: A reason the owner or operator would make the
choice described in paragraph (a)(2) of this section is if the plant
site, without this limit, would be a major source. The owner or operator
could use this limit, which would establish the potential to emit from
magnetic tape manufacturing operations, in conjunction with the
potential to emit from the other HAP emission points at the stationary
source, to be an area source. Note, however, that an owner or operator
is not required to use the provisions in Sec. 63.703(b) and (h) to
determine the potential to emit HAP from magnetic tape manufacturing
operations.
(b) This subpart does not apply to the following:
(1) Research or laboratory facilities; and
(2) Any coating operation that produces a quantity of magnetic tape
that is 1 percent or less of total production (in terms of total square
footage coated) from that coating operation in any 12-month period.
(c) The affected source subject to this standard is the magnetic
tape manufacturing operation, as defined in Sec. 63.702.
(d) An owner or operator of an existing affected source subject to
the provisions of this subpart shall comply according to the following
schedule:
(1) Within 3 years after the effective date of the standard, if the
owner or operator is required to install a new add-on air pollution
control device to meet the requirements of Sec. 63.703(c) or (g); or
(2) Within 2 years after the effective date of the standard, if a
new add-on air pollution control device is not needed to comply with
Sec. 63.703(c) or (g) of these standards.
(e) The compliance date for an owner or operator of a new affected
source subject to the provisions of this subpart is immediately upon
startup of the affected source.
(f) The provisions of this subpart apply during periods of startup
and shutdown, and whenever magnetic tape manufacturing operations are
taking place.
(g) Owners or operators of affected sources subject to the
provisions of this subpart shall also comply with the requirements of
subpart A as identified in Table 1, according to the applicability of
subpart A to such sources.
[[Page 227]]
(h) In any title V permit for an affected source, all research or
laboratory facilities that are exempt from the requirements of this
subpart shall be clearly identified.
Sec. 63.702 Definitions.
(a) All terms used in this subpart that are not defined below have
the meaning given to them in the Clean Air Act and in subpart A of this
part.
Add-on air pollution control device means equipment installed at the
end of a process vent exhaust stack or stacks that reduces the quantity
of a pollutant that is emitted to the air. The device may destroy or
secure the pollutant for subsequent recovery. Examples are incinerators,
condensers, carbon adsorbers, and biofiltration units. Transfer
equipment and ductwork are not considered in and of themselves add-on
air pollution control devices.
Bag slitter means a device for enclosed transfer of particulates. A
bag of raw materials is placed in a hopper, the hopper is closed, and an
internal mechanism slits the bag, releasing the particulates into either
a closed conveyor that feeds the mix preparation equipment or into the
mix preparation equipment itself.
Base substrate means the surface, such as plastic or paper, to which
a coating is applied.
Capture efficiency means the fraction of all organic vapors or other
pollutants generated by a process that are directed to an add-on air
pollution control device.
Capture device means a hood, enclosed room, or other means of
collecting HAP vapors or other pollutants into a duct that exhausts to
an add-on air pollution control device.
Carbon adsorber vessel means one vessel in a series of vessels in a
carbon adsorption system that contains carbon and is used to remove
gaseous pollutants from a gaseous emission source.
Car seal means a seal that is placed on a device that is used either
to open a closed valve or close an opened valve so that the position of
the valve cannot be changed without breaking the seal.
Closed system for flushing fixed lines means a system in which the
line to be flushed is disconnected from its original position and
connected to two closed containers, one that contains cleaning solvent
and one that is empty. Solvent is flushed from the container with
cleaning solvent, through the line, and into the empty containers.
Coater or coating applicator means the apparatus used to apply a
coating to a continuous base substrate.
Coating application means the process by which the coating mix is
applied to the base substrate.
Coating operation means any coater, flashoff area, and drying oven
located between a base substrate unwind station and a base substrate
rewind station that coats a continuous base substrate.
Control device efficiency means the ratio of the emissions collected
or destroyed by an add-on air pollution control device to the total
emissions that are introduced to the control device, expressed as a
percentage.
Day means a 24-consecutive-hour period.
Drying oven means a chamber that uses heat to bake, cure,
polymerize, or dry a surface coating; if the coating contains volatile
solvents, the volatile portion is evaporated in the oven.
Enclosed transfer method means a particulate HAP transfer method
that uses an enclosed system to prevent particulate HAP from entering
the atmosphere as dust. Equipment used for this purpose may include
vacuum injection systems or other mechanical transfer systems, bag
slitters, or supersacks.
Equivalent diameter means four times the area of an opening divided
by its perimeter.
Facility means all contiguous or adjoining property that is under
common ownership or control in which magnetic tape manufacturing is
performed. The definition includes properties that are separated only by
a road or other public right-of-way.
Flashoff area means the portion of a coating operation between the
coater and the drying oven where solvent begins to evaporate from the
coated base substrate.
Flushing of fixed lines means the flushing of solvent through lines
that are typically fixed and are not associated with the cleaning of a
tank, such
[[Page 228]]
as the line from the mix room to the coater.
Freeboard ratio means the vertical distance from the surface of the
liquid to the top of the sink or tank (freeboard height) divided by the
smaller of the length or width of the sink or tank evaporative area.
Magnetic coatings means coatings applied to base substrates to make
magnetic tape. Components of magnetic coatings may include: Magnetic
particles, binders, dispersants, conductive pigments, lubricants,
solvents, and other additives.
Magnetic particles means particles in the coating mix that have
magnetic properties. Examples of magnetic particles used in magnetic
tape manufacturing are: y-oxide, doped iron oxides, chromium dioxide,
barium ferrite, and metallic particles that usually consist of elemental
iron, cobalt, and/or nickel.
Magnetic tape means any flexible base substrate that is covered on
one or both sides with a coating containing magnetic particles and that
is used for audio recording, video recording, or any type of information
storage.
Magnetic tape manufacturing operation means all of the emission
points within a magnetic tape manufacturing facility that are
specifically associated with the manufacture of magnetic tape. These

(2) Mix preparation equipment;
(3) Coating operations;
(4) Waste handling devices;
(5) Particulate transfer operations;
(6) Wash sinks for cleaning removable parts;

(8) Wastewater treatment systems; and
(9) Condenser vents associated with distillation and stripping
columns in the solvent recovery area, but not including the vent on a
condenser that is used as the add-on air pollution control device.
Mill means the pressurized equipment that uses the dispersing action
of beads, combined with the high shearing forces of the centrifugal
mixing action, to disperse the aggregates of magnetic particles
thoroughly without reducing particle size.
Mix preparation equipment means the vessels, except for mills, used
to prepare the magnetic coating.
Natural draft opening means any opening in a room, building, or
total enclosure that remains open during operation of the facility and
that is not connected to a duct in which a fan is installed. The rate
and direction of the natural draft through such an opening is a
consequence of the difference in pressures on either side of the wall
containing the opening.
Nonregenerative carbon adsorber means a carbon adsorber vessel in
which the spent carbon bed does not undergo carbon regeneration in the
adsorption vessel.
Operating parameter value means a minimum or maximum value
established for a control device or process parameter that, if achieved
by itself or in combination with one or more other operating parameter
values, determines that an owner or operator has complied with an
applicable emission limitation or standard.
Overall HAP control efficiency means the total efficiency of the
control system, determined by the product of the capture efficiency and
the control device efficiency.
Particulate means any material, except uncombined water, that exists
as liquid or solid particles such as dust, smoke, mist, or fumes at
standard conditions (760 millimeters of mercury, 0 degrees celsius).
Particulate HAP transfer means the introduction of a particulate HAP
into other dry ingredients or a liquid solution.
Removable parts cleaning means cleaning of parts that have been
moved from their normal position to a wash tank or sink containing
solvent for the purpose of cleaning.
Research or laboratory facility means any stationary source whose
primary purpose is to conduct research and development to develop new
processes and products, where such source is operated under the close
supervision of technically trained personnel and is not engaged in the
manufacture of products for commercial sale in commerce, except in a de
minimis manner.
[[Page 229]]
Separator means a device in the wastewater treatment system in which
immiscible solvent is physically separated from the water with which it
is mixed.
Solvent storage tanks means the stationary tanks that are associated
with magnetic tape operations and that store virgin solvent, spent
solvent, cleaning solvent, solvent at any stage of the solvent recovery
process, or any volatile compound. They do not serve a process function.
Solvent recovery area means the collection of devices used to remove
HAP emissions from process air, to recover the HAP, and to purify the
HAP. Typically, this area contains a control device such as a carbon
adsorber or condenser, the wastewater treatment system, and the
distillation columns.
Solvent recovery device means, for the purposes of this subpart, an
add-on air pollution control device in which HAP is captured rather than
destroyed. Examples include carbon adsorption systems and condensers.
Supersack means a container of particulate from the manufacturer or
supplier with attached feed tubes and that is used to transfer
particulate under the following conditions: the feed tubes are attached
directly to the mix preparation equipment, the attachment interface is
sealed, and all openings on the mix transfer equipment are closed to the
atmosphere.
Temporary total enclosure means a total enclosure that is
constructed for the sole purpose of measuring the fugitive emissions
from an affected source. A temporary total enclosure must be constructed
and ventilated (through stacks suitable for testing) so that it has
minimal impact on the performance of the permanent capture system. A
temporary total enclosure will be assumed to achieve total capture of
fugitive emissions if it conforms to the requirements found in Sec.
63.705(c)(4)(i) and if all natural draft openings are at least four duct
or hood equivalent diameters away from each exhaust duct or hood.
Alternatively, the owner or operator may apply to the Administrator for
approval of a temporary enclosure on a case-by-case basis.
Total enclosure means a structure that is constructed around a
gaseous emission source so that all gaseous pollutants emitted from the
source are collected and ducted through a control device, such that 100
percent capture efficiency is achieved. There are no fugitive emissions
from a total enclosure. The only openings in a total enclosure are
forced makeup air and exhaust ducts and any natural draft openings such
as those that allow raw materials to enter and exit the enclosure for
processing. All access doors or windows are closed during routine
operation of the enclosed source. Brief, occasional openings of such
doors or windows to accommodate process equipment adjustments are
acceptable, but if such openings are routine or if an access door
remains open during the entire operation, the access door must be
considered a natural draft opening. The average inward face velocity
across the natural draft openings of the enclosure must be calculated
including the area of such access doors. The drying oven itself may be
part of the total enclosure. A permanent enclosure that meets the
requirements found in Sec. 63.705(c)(4)(i) is a total enclosure.
Utilize means the use of HAP that is delivered to mix preparation
equipment for the purpose of formulating coatings, the use of any other
HAP (e.g., dilution solvent) that is added at any point in the
manufacturing process, and the use of any HAP for cleaning activities.
Alternatively, annual HAP utilization can be determined as net usage;
that is, the HAP inventory at the beginning of a 12-month period, plus
the amount of HAP purchased during the 12-month period, minus the amount
of HAP in inventory at the end of a 12-month period.
Vacuum injection system means a system in which a vacuum draws
particulate from a storage container into a closed system that transfers
particulates into the mix preparation equipment.
Volatile organic compound (VOC) means any organic compound that
participates in atmospheric photochemical reactions or that is measured
by EPA Test Methods 18, 24, or 25A in appendix A of part 60 or an
alternative test method as defined in Sec. 63.2.
[[Page 230]]
Volatile organic hazardous air pollutant (VOHAP) concentration means
the concentration of an individually-speciated organic HAP in a
wastewater discharge that is measured by Method 305 of appendix A to 40
CFR part 63.
Waste handling means processing or treatment of waste (liquid or
solid) that is generated as a by-product of either the magnetic tape
production process or cleaning operations.
Waste handling device means equipment that is used to separate
solvent from solid waste (e.g., filter dryers) or liquid waste (e.g.,
pot stills and thin film evaporators). The solvents are recovered by
heating, condensing, and collection.
Wastewater discharge means the water phase that is discharged from
the separator in a wastewater treatment system.
Wastewater treatment system means the assortment of devices in which
the solvent/water mixture, generated when the carbon bed in the carbon
adsorber is desorbed by steam, is treated to remove residual organics in
the water.

reporting requirements of Sec. Sec. 63.706(d), 63.707(d), and
63.707(i)(5). The provisions of Sec. 63.8(b) (2) and (3), (c), (d),
(e), (f), and (g) (1), and (2) of subpart A do not apply.
(10) The owner or operator of an affected emission point using a
vent system that contains bypass lines (not including equipment such as
low leg drains, high point bleeds, analyzer vents, open-ended valves or
lines, and pressure relief valves needed for safety purposes) that could
potentially divert a vent stream away from the control device used to
comply with Sec. 63.703 (c)(1), (c)(2), (c)(3), (c)(4), (e)(1)(i),
(f)(1)(i), or (i) shall:
(i) Install, calibrate, maintain, and operate a flow indicator that
provides a record of vent stream flow at least once every 15 minutes;
records shall be generated as specified in Sec. 63.706(c)(1); and the
flow indicator shall be installed at the entrance to any bypass line
that could divert the vent stream away from the control device to the
atmosphere; or
(ii) 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 shall be performed at least once every month
to ensure that the valve is maintained in the closed position and the
vent stream is not diverted through the bypass line; or
(iii) Ensure that any bypass line valve is in the closed position
through continuous monitoring of valve position; the monitoring system
shall be inspected at least once every month to ensure that it is
functioning properly; or
(iv) Use an automatic shutdown system in which any HAP-emitting

(d) Owners or operators complying with Sec. 63.703(g) shall
demonstrate continuous compliance in accordance with paragraph (d)(1) or
(d)(2) of this section.
(1) An owner or operator that established the steam-to-feed ratio as
the site-specific operating parameter in accordance with Sec.
63.704(b)(10)(i) shall continuously measure the steam-to-feed ratio
whenever HAP-containing wastewater from magnetic tape manufacturing
operations is being fed to the steam stripper. Operation of the steam
stripper at a steam-to-feed ratio less than the operating parameter
value or values established in accordance with Sec. 63.704(b)(10)(i)
for any 3-hour period shall constitute a violation of Sec. 63.703(g).

also install, calibrate, and operate the instrumentation necessary to
continuously monitor the ventilation air flow rate in the inlet duct to
the baghouse or fabric filter whenever particulate HAP transfer occurs.
The occurrence of visible emissions shall constitute a violation of
Sec. 63.703(d)(2), and the operation of the baghouse or fabric filter
at a flow rate less than the value or values established in accordance
with Sec. 63.704(b)(7) for any 3-hour period shall constitute a
violation of Sec. 63.703(d)(2).
(f) An owner or operator who uses an air pollution control device

Sec. 63.705 Performance test methods and procedures to determine
initial compliance.
(a) Except as specified in Sec. 63.705(a) (1) through (3), to
determine initial compliance with the emission limits under Sec. 63.703
(c), (d)(2), (e)(1), (f)(1), and (g), the owner or operator shall
conduct an initial performance demonstration as required under Sec.
63.7 using the procedures and test methods listed in Sec. 63.7 and
Sec. 63.705. If multiple emission points are vented to one common
control device to meet the requirements of Sec. 63.703 (c), (d)(2),
(e)(1), and (f)(1), only one performance test is required to demonstrate
initial compliance for that group of emission points. This section also
contains initial compliance demonstration procedures (other than
testing) for owners or operators subject to Sec. 63.703 (c), (d)(1),
(e)(1)(ii), (f)(1)(ii), and (g).
(1) A control device (not enclosure) used to comply with Sec.
63.703 (c), (e), or (f) does not need to be tested if each of the
following criteria are met:
(i) It is used to control gaseous HAP emissions from an existing
affected source;
(ii) It is operating prior to March 11, 1994;
(iii) It is equipped with continuous emission monitors for
determining inlet and outlet total HAP or VOC concentration, such that a
percent efficiency can be calculated; and
(iv) The continuous emission monitors are used to demonstrate
continuous compliance in accordance with Sec. 63.704(c)(3)(i).
(2) The owner or operator is not required to conduct an initial
performance test if the requirements of Sec. 63.7(e)(2)(iv) or Sec.
63.7(h) are met.
(3) An owner or operator is not required to conduct an initial
performance test for a capture device when:
(i) The room, enclosure, or vent was previously tested to
demonstrate compliance with subpart SSS of part 60; and
(ii) Sufficient data were gathered during the test to establish
operating parameter values in accordance with Sec. 63.704(b)(6) (i),
(ii), and (iii).
(b) When an initial compliance demonstration is required by this
subpart, the procedures in paragraphs (b)(1) through (b)(10) of this
section shall be used in determining initial compliance with the
provisions of this subpart.
(1) EPA Method 24 of appendix A of part 60 is used to determine the
VOC
[[Page 242]]
content in coatings. If it is demonstrated to the satisfaction of the
Administrator that plant coating formulation data are equivalent to EPA
Method 24 results, formulation data may be used. In the event of any
inconsistency between an EPA Method 24 test and an affected source's
formulation data, the EPA Method 24 test will govern. For EPA Method 24,
the coating sample must be a 1-liter sample taken into a 1-liter
container at a location and time such that the sample will be
representative of the coating applied to the base substrate (i.e., the
sample shall include any dilution solvent or other VOC added during the
manufacturing process). The container must be tightly sealed immediately
after the sample is taken. Any solvent or other VOC added after the
sample is taken must be measured and accounted for in the calculations
that use EPA Method 24 results.
(2) Formulation data is used to determine the HAP content of
coatings.
(3) Either EPA Method 18 or EPA Method 25A of appendix A of part 60,
as appropriate to the conditions at the site, shall be used to determine
HAP or VOC concentration of air exhaust streams as required by Sec.
63.705(c). The owner or operator shall submit notice of the intended
test method to the Administrator for approval along with the
notification of the performance test required under Sec. 63.7(b).
Method selection shall be based on consideration of the diversity of
organic species present and their total concentration and on
consideration of the potential presence of interfering gases. Except as
indicated in paragraphs (b)(3) (i) and (ii) of this section, the test
shall consist of three separate runs, each lasting a minimum of 30
minutes.
(i) When either EPA Method 18 or EPA Method 25A is to be used in the
determination of the efficiency of a fixed-bed carbon adsorption system
with a common exhaust stack for all the individual carbon adsorber
vessels pursuant to Sec. 63.705(c) (2) or (4), the test shall consist
of three separate runs, each coinciding with one or more complete
sequences through the adsorption cycles of all of the individual carbon
adsorber vessels.
(ii) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with individual exhaust stacks for each carbon adsorber vessel
pursuant to Sec. 63.705(c) (3) or (4), each carbon adsorber vessel
shall be tested individually. The test for each carbon adsorber vessel
shall consist of three separate runs. Each run shall coincide with one
or more complete adsorption cycles.
(4) EPA Method 1 or 1A of appendix A of part 60 is used for sample
and velocity traverses.
(5) EPA Method 2, 2A, 2C, or 2D of appendix A of part 60 is used for
velocity and volumetric flow rates.
(6) EPA Method 3 of appendix A of part 60 is used for gas analysis.
(7) EPA Method 4 of appendix A of part 60 is used for stack gas
moisture.
(8) EPA Methods 2, 2A, 2C, 2D, 3, and 4 shall be performed, as
applicable, at least twice during each test period.
(9) Wastewater analysis shall be conducted in accordance with
paragraph (b)(9)(i) or (b)(9)(ii) of this section.
(i) Use Method 305 of 40 CFR part 63, appendix A and the equations
in paragraphs (b)(9)(i) (A) and (B) of this section to determine the
total VOHAP concentration of a wastewater stream.
(A) The following equation shall be used to calculate the VOHAP
concentration of an individually speciated HAP.
[GRAPHIC] [TIFF OMITTED] TR15DE94.003
[[Page 243]]
where:
Ci = VOHAP concentration of the individually-speciated
organic HAP in the wastewater, parts per million by weight.
Cc = Concentration of the organic HAP (i) in the gas stream,
as measured by Method 305 of appendix A of this part, parts
per million by volume on a dry basis.
Ms = Mass of sample, from Method 305 of appendix A of this
part, milligrams.
MW = Molecular weight of the organic HAP (i), grams per gram-mole.
24.055 = Ideal gas molar volume at 293[deg] Kelvin and 760 millimeters
of mercury, liters per gram-mole.
Pi = Barometric pressure at the time of sample analysis,
millimeters mercury absolute.
760 = Reference or standard pressure, millimeters mercury absolute.
293 = Reference or standard temperature, [deg]Kelvin.
Ti = Sample gas temperature at the time of sample analysis,
[deg]Kelvin.
t = Actual purge time, from Method 305 of appendix A of this part,
minutes.
L = Actual purge rate, from Method 305 of appendix A of this part,
liters per minute.
10\3\ = Conversion factor, milligrams per gram.
(B) Total VOHAP concentration (stream) can be determined by summing
the VOHAP concentrations of all individually speciated organic HAP in
the wastewater.
[GRAPHIC] [TIFF OMITTED] TR15DE94.004
where:
Cstream = Total VOHAP concentration of wastewater stream.
n = Number of individual organic HAP (i) in the wastewater stream.
Ci = VOHAP concentration of individual organic HAP (i)
calculated according to the procedures in paragraph
(b)(9)(i)(A) of this section.
(ii) Use a test method or results from a test method that measures
organic HAP concentrations in the wastewater, and that has been
validated according to section 5.1 or 5.3 of Method 301 of appendix A of
this part. The specific requirement of Method 305 of appendix A of this
part to collect the sample into polyethylene glycol would not be
applicable.
(A) If measuring the total VOHAP concentration of the exit stream in
accordance with Sec. Sec. 63.703(g)(1)(ii) and 63.705(h)(2), the
concentrations of the individual organic HAP measured in the water shall
be corrected to their concentrations had they been measured by Method
305 of appendix A of this part. This is done by multiplying each
concentration by the compound-specific fraction measured factor
(FM) listed in table 34 of 40 CFR part 63, subpart G.
(B) If measuring the total HAP concentration of an inlet and outlet
wastewater stream to demonstrate compliance with Sec. 63.703(g)(1)(i)
and following the procedures of Sec. 63.705(h)(3), the concentrations
of the individual organic HAP measured in the water do not need to be
corrected.
(10) EPA Method 22 of appendix A of part 60 is used to determine
visible emissions. Visible emissions testing shall be conducted for a
minimum of 6 minutes during a time when particulate HAP transfer, as
defined in this subpart, is occurring.
(c) Initial compliance demonstrations. Except as stipulated in Sec.
63.705(a), each owner or operator subject to the requirements of Sec.
63.703(c) must demonstrate initial compliance with the requirements of
this subpart by following the procedures of paragraphs (c)(1), (2), (3),
(4), (5), or (6) and paragraph (d) of this section, as applicable. Each

following the procedures of paragraphs (e), (f), (g), and (h) of this
section, as appropriate.
(1) To demonstrate initial and continuous compliance with Sec.
63.703(c)(1), (c)(3), or (c)(4) when emissions from only the affected
coating operations are controlled by a dedicated solvent recovery
device, each owner or operator of the affected coating operation may
perform a liquid-liquid HAP or VOC material balance over rolling 7-day
periods in lieu of demonstrating compliance through the methods in
paragraphs (c)(2), (c)(3), or (c)(4) of this section. Results of the
material balances calculation performed to demonstrate initial
compliance shall be submitted to the Administrator with the notification
of compliance status required by Sec. 63.9(h) and Sec. 63.707(d). When
demonstrating compliance by
[[Page 244]]
this procedure, Sec. 63.7(e)(3) of subpart A does not apply. The amount
of liquid HAP or VOC applied and recovered shall be determined as
discussed in paragraph (c)(1)(iii) of this section. The overall HAP or
VOC emission reduction (R) is calculated using equation 1:
[GRAPHIC] [TIFF OMITTED] TR15DE94.005

(B) Documentation that the measured value of RSi exceeds
zero.
(ii) The measurement techniques of paragraph (c)(1)(i)(A) of this
section shall be submitted to the Administrator for approval with the
notification of performance test required under Sec. 63.7(b).

certification shall be kept on record;
(D) Measure the amount of HAP or VOC recovered; and
(E) Calculate the overall HAP or VOC emission reduction (R) for
rolling 7-day periods using Equation 1.
(iv) Compliance is demonstrated if the value of R is equal to or
greater than the overall HAP control efficiency required by Sec. 63.703
(c)(1), (c)(3), or (c)(4).
(2) To demonstrate initial compliance with Sec. 63.703 (c)(1),
(c)(2), (c)(3), or (c)(4) when affected HAP emission points are

adsorption system with individual exhaust stacks for each carbon
adsorber vessel, each owner or operator of an affected source shall
perform a gaseous emission test using the following procedures.
(i) Construct the overall HAP emission reduction system so that all
volumetric flow rates and total HAP or VOC emissions can be accurately
determined by the applicable test methods and procedures specified in
Sec. 63.705(b) (3) through (8).
(ii) Determine capture efficiency from the HAP emission points by
capturing, venting, and measuring all HAP emissions from the HAP
emission points. During a performance test, the owner or operator of
affected HAP emission points located in an area with other gaseous
emission sources not affected by this subpart shall isolate the affected
HAP emission points from all other gaseous emission points by one of the
following methods:
(A) Build a temporary total enclosure (see Sec. 63.702) around the
affected HAP emission point(s); or
(B) Shut down all gaseous emission points not affected by this
subpart and continue to exhaust fugitive emissions from the affected HAP
emission points through any building ventilation system and other room
exhausts such as drying ovens.
All ventilation air must be vented through stacks suitable for
testing.
(iii) Operate the emission control device with all affected HAP
emission points connected and operating.
(iv) Determine the efficiency (E) of the control device using
equation 2:
[GRAPHIC] [TIFF OMITTED] TR15DE94.006
(v) Determine the efficiency (F) of the capture system using
equation 3:
[[Page 245]]
[GRAPHIC] [TIFF OMITTED] TR15DE94.007
(vi) For each HAP emission point subject to Sec. 63.703, compliance
is demonstrated if either of the following conditions are met:
(A) The product of (E) x (F) is equal to or greater than the overall

compound, on a dry basis.
(3) To demonstrate compliance with Sec. 63.703(c)(1), (c)(3), or
(c)(4) when affected HAP emission points are controlled by a fixed-bed
carbon adsorption system with individual exhaust stacks for each carbon
adsorber vessel, each owner or operator of an affected source shall
perform a gaseous emission test using the following procedures:
(i) Construct the overall HAP emission reduction system so that each
volumetric flow rate and the total HAP emissions can be accurately
determined by the applicable test methods and procedures specified in
Sec. 63.705(b) (3) through (8);
(ii) Assure that all HAP emissions from the affected HAP emission
point(s) are segregated from gaseous emission points not affected by
this subpart and that the emissions can be captured for measurement, as
described in Sec. 63.705(c)(2)(ii) (A) and (B);
(iii) Operate the emission control device with all affected HAP
emission points connected and operating;
(iv) Determine the efficiency (Hv) of each individual

[GRAPHIC] [TIFF OMITTED] TR15DE94.009
(vi) Determine the efficiency (F) of the capture system using
equation (3).
(vii) For each HAP emission point subject to Sec. 63.703(c),
compliance is demonstrated if the product of (Hsys) x (F) is
equal to or greater than the overall HAP control efficiency required by
Sec. 63.703(c)(1), (c)(3), or (c)(4).
(4) An alternative method of demonstrating compliance with Sec.
63.703(c)(1) through (c)(4) is the installation of a total enclosure
around the affected HAP emission point(s) and the ventilation of all HAP
emissions from the total enclosure to a control device with the
efficiency or outlet concentration specified in paragraph (c)(4)(iii) of
this section. If this method is selected, the compliance test methods
described in paragraphs (c)(1), (c)(2), and (c)(3) of this section are
not required. Instead, each owner or operator of an affected source
shall:
(i) Demonstrate that a total enclosure is installed. An enclosure
that meets the requirements in paragraphs (c)(4)(i) (A) through (D) of
this section shall be considered a total enclosure. The owner or
operator of an enclosure that does not meet these requirements may apply
to the Administrator for approval of the enclosure as a total enclosure
on a case-by-case basis. The enclosure shall be considered a total
enclosure if it is demonstrated to the satisfaction of the Administrator
that all HAP emissions from the affected HAP emission point(s) are
contained and vented to the control device. The requirements for
automatic approval are as follows:
(A) Total area of all natural draft openings shall not exceed 5
percent of the total surface area of the total enclosure's walls, floor,
and ceiling;
(B) All sources of emissions within the enclosure shall be a minimum
of
[[Page 246]]
four equivalent diameters away from each natural draft opening;
(C) Average inward face velocity (FV) across all natural draft
openings shall be a minimum of 3,600 meters per hour as determined by
the following procedures:
(1) All forced makeup air ducts and all exhaust ducts are
constructed so that the volumetric flow rate in each can be accurately
determined by the test methods and procedures specified in Sec.
63.705(b) (4) and (5); volumetric flow rates shall be calculated without
the adjustment normally made for moisture content; and
(2) Determine FV by equation 6:
[GRAPHIC] [TIFF OMITTED] TR15DE94.010
(D) The air passing through all natural draft openings shall flow
into the enclosure continuously. If FV is less than or equal to 9,000
meters per hour, the continuous inward flow of air shall be verified by
continuous observation using smoke tubes, streamers, tracer gases, or
other means approved by the Administrator over the period that the
volumetric flow rate tests required to determine FV are carried out. If
FV is greater than 9,000 meters per hour, the direction of airflow
through the natural draft openings shall be presumed to be inward at all
times without verification.
(ii) Determine the control device efficiency using equation (2) or
equations (4) and (5), as applicable, and the test methods and
procedures specified in Sec. 63.705(b) (3) through (8).

determined from equations (4) and (5), as applicable) is equal to or
greater than the overall HAP control efficiency required by Sec. 63.703
(c)(1), (c)(3), or (c)(4); or
(B) When the owner or operator is subject to Sec. 63.703(c)(2), the
installation of a total enclosure is demonstrated and the value of
Caj at the outlet of the incinerator is demonstrated to be no
greater than 20 ppmv by compound, on a dry basis.
(5) To demonstrate initial and continuous compliance with Sec.
63.703(c)(5), each owner or operator of an affected source shall
determine the mass of HAP contained in the coating per volume of coating
solids applied for each batch of coating applied, according to the
procedures of paragraphs (c)(5) (i) through (iii) of this section. If a
batch of coating is identical to a previous batch of coating applied,
the original calculations can be used to demonstrate the compliance of
subsequent identical batches. The calculation of the HAP content of the
coating used to demonstrate initial compliance with Sec. 63.703(c)(5)
shall be submitted to the Administrator with the notification of
compliance status required by Sec. 63.9(h) and Sec. 63.707(e). When
demonstrating compliance by this procedure, Sec. 63.7(e)(3) of subpart
A does not apply.
(i) Determine the weight fraction of HAP in each coating applied
using formulation data as specified in Sec. 63.705(b)(2);
(ii) Determine the volume of coating solids in each coating applied
from the facility records; and
(iii) Compute the mass of HAP per volume of coating solids by
equation 7:
[[Page 247]]
[GRAPHIC] [TIFF OMITTED] TR15DE94.011
(iv) The owner or operator of an affected source is in compliance
with Sec. 63.703(c)(5) if the value of G is less than or equal to 0.18
kilogram of HAP per liter of coating solids applied.
(6) When nonregenerative carbon adsorbers are used to comply with
Sec. 63.703(c)(1), the owner or operator may conduct a design
evaluation to demonstrate initial compliance in lieu of following the
compliance test procedures of paragraph (c) (1), (2), (3), or (4) of
this section. The design evaluation shall consider the vent stream
composition, constituent concentrations, flow rate, relative humidity,
and temperature, and shall establish the design exhaust vent stream
organic compound concentration level, capacity of the carbon bed, type
and working capacity of activated carbon used for the carbon bed, and
design carbon replacement interval based on the total carbon working
capacity of the control device and the emission point operating
schedule.
(d)(1) To demonstrate initial compliance with Sec. 63.703(c) when
hard piping or ductwork is used to direct HAP emissions from a HAP
source to the control device, each owner or operator shall demonstrate
upon inspection that the criteria of paragraph (d)(1)(i) and paragraph
(d)(1) (ii) or (iii) are met.
(i) The equipment must be vented to a control device.
(ii) The control device efficiency (E or Hsys, as
applicable) determined using equation (2) or equations (4) and (5),
respectively, and the test methods and procedures specified in Sec.
63.705(b) (3) through (8), must be equal to or greater than the overall
HAP control efficiency required by Sec. 63.703 (c)(1), (c)(3), or
(c)(4), or the outlet concentration must be no greater than 20 ppmv by
compound, on a dry basis, as required by Sec. 63.703(c)(2).
(iii) When a nonregenerative carbon adsorber is used, the ductwork
from the affected emission point(s) must be vented to the control device
and the carbon adsorber must be demonstrated, through the procedures of
Sec. 63.705(c) (1), (2), (3), (4), or (6) to meet the requirements of

owner or operator of a wash sink subject to the provisions of this
standard shall:
(1) If complying with Sec. 63.703(e)(1)(ii), maintain at least the
required minimum freeboard ratio at all times; or

or (ii). A minimum of three representative samples of the wastewater
stream exiting the treatment process, which are representative of normal
flow and concentration conditions, shall be collected and analyzed.
Wastewater samples shall be collected using the sampling procedures
specified in Method 25D of appendix A of part 60. Where feasible,
samples shall be taken from an enclosed pipe prior to the wastewater
being exposed to the atmosphere. When sampling from an enclosed pipe is
not feasible, a minimum of three representative samples shall be
collected in a manner that minimizes exposure of the sample to the
atmosphere and loss of organic HAP prior to analysis.
(3) The owner or operator shall demonstrate the compliance of a
treatment process with the HAP fraction removed requirement specified in
Sec. 63.703(g)(1)(i) by measuring the concentration of each HAP at the
inlet and outlet of the treatment process using the method specified in
Sec. 63.705(b)(9) (i) or (ii) and the procedures of paragraphs (h)(3)
(i) through (iii) of this section.
(i) The same test method shall be used to analyze the wastewater
samples from both the inlet and outlet of the treatment process.
(ii) The HAP mass flow rate of each individually speciated HAP
compound entering the treatment process (Eb) and exiting the
treatment process (Ea) shall be determined by computing the
product of the flow rate of the wastewater stream entering or exiting
the treatment process, and the HAP concentration of each individual HAP
compound of the entering or exiting wastewater streams, respectively.
(A) The flow rate of the entering and exiting wastewater streams
shall be determined using inlet and outlet flow meters, respectively.
(B) The average HAP concentration of each individual HAP of the
entering and exiting wastewater streams shall be determined according to
the procedures specified in either paragraph (b)(9)(i)(A) or
(b)(9)(ii)(B) of this section. If measuring the VOHAP concentration of
an individual HAP in accordance with Sec. 63.705(b)(9)(i)(A), the
concentrations of the individual organic VOHAP measured in the water
shall be corrected to a HAP concentration by dividing each VOHAP
concentration by the compound-specific fraction measured factor
(FM) listed in table 34 of 40 CFR part 63, subpart G.
[[Page 249]]
(C) Three grab samples of the entering wastewater stream shall be
taken at equally spaced time intervals over a 1-hour period. Each 1-hour
period constitutes a run, and the performance test shall consist of a
minimum of three runs.

taken at equally spaced time intervals over a 1-hour period. Each 1-hour
period constitutes a run, and the performance test shall consist of a
minimum of three runs conducted over the same 3-hour period at which the
total HAP mass flow rate entering the treatment process is determined.
(E) The HAP mass flow rates of each individual HAP compound entering
and exiting the treatment process are calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR15DE94.012
where:
Eb = HAP mass flow rate of an individually speciated HAP
compound entering the treatment process, kilograms per hour.
Ea = HAP mass flow rate of an individually speciated HAP
compound exiting the treatment process, kilograms per hour.
K = Density of the wastewater stream, kilograms per cubic meter.
Vbp = Average volumetric flow rate of wastewater entering the
treatment process during each run p, cubic meters per hour.
Vap = Average volumetric flow rate of wastewater exiting the
treatment process during each run p, cubic meters per hour.
Cbp = Average HAP concentration of an individually speciated
HAP in the wastewater stream entering the treatment process
during each run p, parts per million by weight.
Cap = Average HAP concentration of an individually speciated
HAP in the wastewater stream exiting the treatment process
during each run p, parts per million by weight.
n = Number of runs.
(iii) The fraction removed across the treatment process for each
individually speciated HAP compound shall be calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR15DE94.013
where:
FR = Fraction removed for an individually speciated HAP
compound of the treatment process.
Eb = HAP mass flow rate of an individually speciated HAP
compound entering the treatment process, kilogram per hour.

that HAP solvent is added to the wash sink. A measurement of the actual
ratio is not necessary for each record as long as the owner or operator
has a reliable method for making the required determination. For
example, the record may be made by comparing the HAP solvent level to a
permanent mark on the sink that corresponds to a 75 percent freeboard
ratio. A HAP solvent level in the sink higher than the mark would
indicate the minimum ratio has not been achieved.

affected source that are not delivered to an emission control device. A
temporary total enclosure must be constructed and ventilated (through
stacks suitable for testing) so that it has minimal impact on the
performance of the permanent emission capture system. A temporary total
enclosure will be assumed to achieve total capture of fugitive emissions
if it conforms to the requirements found in Sec. 63.750(g)(4) and if

are forced makeup air and exhaust ducts and any natural draft openings
such as those that allow raw materials to enter and exit the enclosure
for processing. All access doors or windows are closed during routine
operation of the enclosed source. Brief, occasional openings of such
doors or windows to accommodate process equipment adjustments are
acceptable, but if such openings are routine or if an access door
remains open during the entire operation, the access door must be
considered a natural draft opening. The average inward face velocity
across the natural draft openings of the enclosure must be calculated
including the area of such access doors. The drying oven itself may be
part of the total enclosure. An enclosure that meets the requirements
found in Sec. 63.750(g)(4) is a permanent total enclosure.

varying amounts of dissolved sulfur and does not contain amines.
Type II etchant means a chemical milling etchant that is a strong
sodium hydroxide solution containing amines.
Volatile organic compound (VOC) means any compound defined as VOC in
40 CFR 51.100. This includes any organic compound other than those
determined by the EPA to be an exempt solvent. For purposes of
determining compliance with emission limits, VOC will be measured by the
approved test methods. Where such a method also inadvertently measures
compounds that are exempt solvent, an owner or operator may exclude
these exempt solvents when determining compliance with an emission
standard.
Waterborne (water-reducible) coating means any coating that contains
more than 5 percent water by weight as applied in its volatile fraction.
Waterwash system means a control system that utilizes flowing water
(i.e., a conventional waterwash system) or a pumpless system to remove

(d) Instead of complying with the individual coating limits in
Sec. Sec. 63.745 and 63.747, a facility may choose to comply with the
averaging provisions specified in paragraphs (d)(1) through (d)(6) of
this section.
(1) Each owner or operator of a new or existing source shall use any
combination of primers, topcoats (including self-priming topcoats),
specialty coatings, Type I chemical milling maskants, or Type II
chemical milling maskants such that the monthly volume-weighted average
organic HAP and VOC contents of the combination of primers, topcoats,
specialty coatings, Type I chemical milling maskants, or Type II
chemical milling maskants, as determined in accordance with the
applicable procedures set forth in Sec. 63.750, complies with the
specified content limits in Sec. Sec. 63.745(c) and 63.747(c), unless
the permitting agency specifies a shorter averaging period as part of an
ambient ozone control program.
(2) Averaging is allowed only for uncontrolled primers, topcoats
(including self-priming topcoats), specialty coatings, Type I chemical
milling maskants, or Type II chemical milling maskants.
(3) Averaging is not allowed between specialty coating types defined
in appendix A to this subpart, or between the different types of
coatings specified in paragraphs (d)(3)(i) through (vii) of this
section.
(i) Primers and topcoats (including self-priming topcoats).
(ii) Type I and Type II chemical milling maskants.
(iii) Primers and chemical milling maskants.
(iv) Topcoats and chemical milling maskants.

(vii) Chemical milling maskants and specialty coatings.
(4)--(5) [Reserved]
(6) Each averaging scheme shall be approved in advance by the
permitting agency and adopted as part of the facility's title V permit.
(e) At all times, the owner or operator must operate and maintain
any affected source, including associated air pollution control
equipment and monitoring equipment, in a manner consistent with safety
and good air pollution control practices for minimizing emissions. The
general duty to minimize emissions does not require the owner or
operator to make any further efforts to reduce emissions if levels
required by the applicable standard have been achieved. Determination of
whether a source is operating in compliance with operation and
maintenance requirements will be based on information available to the
Administrator which may include, but is not limited to, monitoring
results, review of operation and maintenance procedures, review of
operation and maintenance records, and inspection of the source.

Sec. 63.744 Standards: Cleaning operations.
(a) Housekeeping measures. Each owner or operator of a new or
existing cleaning operation subject to this subpart shall comply with
the requirements in paragraphs (a)(1) through (4) of this section unless
the cleaning solvent used is identified in Table 1 of this section or
meets the definition of ``Non-HAP material'' in 63.742. The requirements
of paragraphs (a)(1) through (4) of this section do not apply to spent
cleaning solvents, and solvent-laden applicators that are subject to and
handled and stored in compliance
[[Page 265]]
with 40 CFR parts 262 through 268 (including the air emission control
requirements in 40 CFR part 265, subpart CC).
(1) Unless the owner or operator satisfies the requirements in
paragraph (a)(4) of this section, place used solvent-laden cloth, paper,
or any other absorbent applicators used for cleaning in bags or other
closed containers. Ensure that these bags and containers are kept closed
at all times except when depositing or removing these materials from the
container. Use bags and containers of such design so as to contain the
vapors of the cleaning solvent. Cotton-tipped swabs used for very small
cleaning operations are exempt from this requirement.
(2) Unless the owner or operator satisfies the requirements in
paragraph (a)(4) of this section, store fresh and spent cleaning
solvents, except semi-aqueous solvent cleaners, used in aerospace
cleaning operations in closed containers.
(3) Conduct the handling and transfer of cleaning solvents to or
from enclosed systems, vats, waste containers, and other cleaning
operation equipment that hold or store fresh or spent cleaning solvents
in such a manner that minimizes spills.
(4) Demonstrate to the Administrator (or delegated State, local, or
Tribal authority) that equivalent or better alternative measures are in
place compared to the use of closed containers for the solvent-laden
materials described in paragraph (a)(1) of this section, or the storage
of solvents described in paragraph (a)(2) of this section.
(b) Hand-wipe cleaning. Each owner or operator of a new or existing
hand-wipe cleaning operation (excluding cleaning of spray gun equipment
performed in accordance with paragraph (c) of this section) subject to
this subpart shall use cleaning solvents that meet one of the
requirements specified in paragraphs (b)(1), (b)(2), and (b)(3) of this
section. Cleaning solvent solutions that contain HAP and VOC below the
de minimis levels specified in Sec. 63.741(f) are exempt from the
requirements in paragraphs (b)(1), (b)(2), and (b)(3) of this section.
(1) Meet one of the composition requirements in Table 1 of this
section;
(2) Have a composite vapor pressure of 45 mm Hg (24.1 in.
H2 O) or less at 20 [deg]C (68 [deg]F); or
(3) Demonstrate that the volume of hand-wipe solvents used in
cleaning operations has been reduced by at least 60% from a baseline
adjusted for production. The baseline shall be established as part of an
approved alternative plan administered by the State. Demonstrate that
the volume of hand-wipe cleaning solvents used in cleaning operations
has been reduced by at least 60 percent from a baseline adjusted for
production. The baseline shall be calculated using data from 1996 and
1997, or as otherwise agreed upon by the Administrator or delegated
State Authority. The baseline shall be approved by the Administrator or
delegated State Authority and shall be included as part of the
facility's title V or part 70 permit.
(c) Spray gun cleaning. Each owner or operator of a new or existing
spray gun cleaning operation subject to this subpart in which spray guns
are used for the application of coatings or any other materials that
require the spray guns to be cleaned shall use one or more of the
techniques, or their equivalent, specified in paragraphs (c)(1) through
(c)(4) of this section. Spray gun cleaning operations using cleaning
solvent solutions that contain HAP and VOC below the de minimis levels
specified in Sec. 63.741(f) are exempt from the requirements in
paragraphs (c)(1) through (c)(4) of this section.
(1)(i) Enclosed system. Clean the spray gun in an enclosed system
that is closed at all times except when inserting or removing the spray
gun. Cleaning shall consist of forcing solvent through the gun.
(ii) If leaks are found during the monthly inspection required in
Sec. 63.751(a), repairs shall be made as soon as practicable, but no
later than 15 days after the leak was found. If the leak is not repaired
by the 15th day after detection, the cleaning solvent shall be removed,
and the enclosed cleaner shall be shut down until the leak is repaired
or its use is permanently discontinued.
[[Page 266]]
(2) Nonatomized cleaning. Clean the spray gun by placing cleaning
solvent in the pressure pot and forcing it through the gun with the
atomizing cap in place. No atomizing air is to be used. Direct the
cleaning solvent from the spray gun into a vat, drum, or other waste
container that is closed when not in use.
(3) Disassembled spray gun cleaning. Disassemble the spray gun and
clean the components by hand in a vat, which shall remain closed at all
times except when in use. Alternatively, soak the components in a vat,
which shall remain closed during the soaking period and when not
inserting or removing components.
(4) Atomizing cleaning. Clean the spray gun by forcing the cleaning
solvent through the gun and direct the resulting atomized spray into a
waste container that is fitted with a device designed to capture the
atomized cleaning solvent emissions.
(5) Cleaning of the nozzle tips of automated spray equipment
systems, except for robotic systems that can be programmed to spray into
a closed container, shall be exempt from the requirements of paragraph
(c) of this section.
(d) Flush cleaning. Each owner or operator of a flush cleaning
operation subject to this subpart (excluding those in which Table 1 or
semi-aqueous cleaning solvents are used) shall empty the used cleaning
solvent each time aerospace parts or assemblies, or components of a
coating unit (with the exception of spray guns) are flush cleaned into
an enclosed container or collection system that is kept closed when not
in use or into a system with equivalent emission control.

airless spray application methods as determined according to the
requirements in Sec. 63.750(i).
(2) All coating spray application devices used to apply primers,
topcoats (including self-priming topcoats), or specialty coatings shall
be operated according to company procedures, local specified operating
procedures, and/or the manufacturer's specifications, whichever is most
stringent, at all times. Spray application equipment modified by the
facility shall maintain a transfer efficiency equivalent to HVLP spray,
electrostatic spray, airless spray, or air-assisted airless spray
application techniques.
(3) The following situations are exempt from the requirements of
paragraph (f)(1) of this section:
(i) Any situation that normally requires an extension on the spray
gun to properly reach limited access spaces;
(ii) The application of coatings that contain fillers that adversely
affect atomization with HVLP spray guns;
(iii) The application of coatings that normally have a dried film
thickness of less than 0.0013 centimeter (0.0005 in.) and that the
permitting agency has determined cannot be applied by any of the
application methods specified in paragraph (f)(1) of this section;
(iv) The use of airbrush application methods for stenciling,
lettering, and other identification markings, and the spray application
of no more than 3.0 fluid ounces of coating in a single application

any one day to any one aerospace vehicle or component) from a hand-held
device with a paint cup capacity that is equal to or less than 3.0 fluid
ounces (89 cubic centimeters). Using multiple small paint cups or
refilling a small paint cup to apply more than 3.0 fluid ounces under
the requirements of this paragraph is prohibited. If a paint cup liner
is used in a reusable holder or cup, then the holder or cup must be
designed to hold a liner with a capacity
[[Page 270]]
of no more than 3.0 fluid ounces. For example, a 3.0 ounce liner cannot
be used in a holder that can also be used with a 6.0 ounce liner under
the requirements of this paragraph;
(v) The use of hand-held non-refillable aerosol containers;
(vi) Touch-up and repair operations;

63.752(e)(7), or the water flow rate, as recorded pursuant to Sec.
63.752(d)(2), exceeds the limit(s) specified by the booth manufacturer
or in locally prepared operating procedures, or the booth manufacturer's
or locally prepared maintenance procedures for the filter or waterwash
system have not been performed as scheduled, shut down the operation
immediately and take corrective action. The operation shall not be
resumed until the pressure drop or water flow rate is returned within
the specified limit(s).
(5) Mechanical and hand sanding operations are exempt from the
requirements in paragraph (b)(4) of this section.
(c) Organic HAP emissions--organic HAP-containing chemical
strippers. Each owner or operator of a new or existing organic HAP-
containing chemical stripper depainting operation subject to this
subpart shall comply with the requirements specified in this paragraph.
(1) All organic HAP emissions from the operation shall be reduced by
the use of a control system. Each control system that was installed
before the effective date shall reduce the operations' organic HAP
emissions to the atmosphere by 81 percent or greater, taking into
account capture and destruction or removal efficiencies.
(2) Each control system installed on or after the effective date
shall reduce organic HAP emissions to the atmosphere by 95 percent or
greater. Reduction shall take into account capture and destruction or
removal efficiencies, and may take into account the volume of chemical

(d) Organic HAP and VOC content levels--primer, topcoat, and
specialty coating application operations--(1) Performance test periods.
For uncontrolled coatings that are not averaged, each 24 hours is
considered a performance test. For compliant and non-compliant coatings
that are averaged together, each 30-day period is considered a
performance test, unless the permitting agency specifies a shorter
averaging period as part of an ambient ozone control program. When using
a control device other than a carbon adsorber, three 1-hour runs
constitute the test period for the initial and any subsequent
performance test. When using a carbon adsorber, each rolling material
balance
[[Page 276]]
period is considered a performance test.
(2) Initial performance tests. If a control device is used, each
owner or operator shall conduct an initial performance test to
demonstrate compliance with the overall reduction efficiency specified
in paragraph Sec. 63.745, unless a waiver is obtained under either
Sec. 63.7(e)(2)(iv) or Sec. 63.7(h). The initial performance test
shall be conducted according to the procedures and test methods
specified in Sec. Sec. 63.7 and 63.750(g) for carbon adsorbers and in
Sec. 63.750(h) for control devices other than carbon adsorbers. For

(3) The primer application operation is considered in compliance
when the conditions specified in paragraphs (d)(3)(i) through (d)(3)(iv)
of this section, as applicable, and in paragraph (e) of this section are
met. Failure to meet any one of the conditions identified in these
paragraphs shall constitute noncompliance. The compliance demonstration
for a primer may be based on the organic HAP content or the VOC content
of the primer; demonstrating compliance with both the HAP content limit
and the VOC content limit is not required. If a primer contains HAP
solvents that are exempt from the definition of VOC in Sec. 63.741 and
40 CFR 51.100, then the HAP content must be used to demonstrate
compliance.
(i) For all uncontrolled primers, all values of Hi and
Ha (as determined using the procedures specified in Sec.
63.750(c) and (d)) are less than or equal to the applicable HAP content
limit in Sec. 63.745(c)(1), and all values of Gi and
Ga (as determined using the procedures specified in Sec.
63.750(e) and (f)) are less than or equal to the applicable VOC content
limit in Sec. 63.745(c)(2).

temperatures for all 3-hour periods are greater than or equal to the
average combustion temperatures established under Sec. 63.751(b)(12).
(iii)(A) Uses an application technique specified in Sec. 63.745
(f)(1)(i) through (f)(1)(viii), or
(B) Uses an alternative application technique, as allowed under
[[Page 277]]
Sec. 63.745(f)(1)(ix), such that the emissions of both organic HAP and
VOC for the implementation period of the alternative application method
are less than or equal to the emissions generated using HVLP or
electrostatic spray application methods as determined using the
procedures specified in Sec. 63.750(i).
(iv) Operates all application techniques in accordance with the
manufacturer's specifications or locally prepared operating procedures,
whichever is more stringent.
(4) The topcoat or specialty coating application operation is
considered in compliance when the conditions specified in paragraphs
(d)(4)(i) through (d)(4)(iv) of this section, as applicable, and in

the VOC content limit is not required. If a topcoat or specialty coating
contains HAP solvents that are exempt from the definition of VOC in
Sec. 63.741 and 40 CFR 51.100, then the HAP content must be used to
demonstrate compliance.
(A) For all uncontrolled topcoats, all values of Hi and
Ha (as determined using the procedures specified in Sec.
63.750(c) and (d)) are less than or equal to the applicable HAP content
limit in Sec. 63.745(c)(3), and all values of Gi and
Ga (as determined using the procedures specified in Sec.
63.750(e) and (f)) are less than or equal to the applicable VOC content
limit in Sec. 63.745(c)(4).
(B) For all uncontrolled specialty coatings, all values of
Hi and Ha (as determined using the procedures
specified in Sec. 63.750(c) and (d)) are less than or equal to the HAP
content limits specified in Table 1 to Sec. 63.745 for the applicable
specialty coating types (less water) as applied, and all values of
Gi and Ga (as determined using the procedures
specified in Sec. 63.750(e) and (f)) are less than or equal to the VOC
content limits specified in Table 1 to Sec. 63.745 for the applicable
specialty coating types (less water and exempt solvents) as applied.
(ii) If a control device is used,
(A) The overall control system efficiency, Ek, as
determined using the procedures specified in Sec. 63.750(g) for control
systems containing carbon adsorbers and in Sec. 63.750(h) for control
systems with other control devices, is equal to or greater than 81%
during the initial performance test and any subsequent performance test;
(B) If an incinerator other than a catalytic incinerator is used,
the average combustion temperature for all 3-hour periods is greater
than or equal to the average combustion temperature established under
Sec. 63.751(b)(11); and
(C) If a catalytic incinerator is used, the average combustion
temperatures for all 3-hour periods are greater than or equal to the
average combustion temperatures established under Sec. 63.751(b)(12).
(iii)(A) Uses an application technique specified in Sec.
63.745(f)(1)(i) through (f)(1)(iv); or
(B) Uses an alternative application technique, as allowed under
Sec. 63.745(f)(1)(v), such that the emissions of both organic HAP and
VOC for the implementation period of the alternative application method
are less than or equal to the emissions generated using HVLP spray,
electrostatic spray, airless spray, or air-assisted airless spray
application methods, as determined using the procedures specified in
Sec. 63.750(i).
(iv) Operates all application techniques in accordance with the
manufacturer's specifications or locally prepared operating procedures.
(e) Inorganic HAP emissions--primer, topcoat, and specialty coating
application operations. For each primer, topcoat, or specialty coating
application operation that emits inorganic HAP, the operation is in
compliance when:
(1) It is operated according to the requirements specified in Sec.
63.745(g)(1) through (g)(3); and
[[Page 278]]
(2) It is shut down immediately whenever the pressure drop or water

restarted until the pressure drop or water flow rate is returned within
these limit(s), as required under Sec. 63.745(g)(3).
(f) Organic HAP emissions--Depainting operations--(1) Performance
test periods. When using a control device other than a carbon adsorber,
three 1-hour runs constitute the test period for the initial and any
subsequent performance test. When a carbon adsorber is used, each
rolling material balance period is considered a performance test. Each
24-hour period is considered a performance test period for determining
compliance with Sec. 63.746(b)(1). For uncontrolled organic emissions
from depainting operations, each calendar year is considered a
performance test period for determining compliance with the HAP limits
for organic HAP-containing chemical strippers used for spot stripping
and decal removal.
(2) Initial performance tests. If a control device is used, each
owner or operator shall conduct an initial performance test to
demonstrate compliance with the overall reduction efficiency specified
in Sec. 63.746(c), unless a waiver is obtained under either Sec.
63.7(e)(2)(iv) or Sec. 63.7(h). The initial performance test shall be
conducted according to the procedures and test methods specified in
Sec. Sec. 63.7 and 63.750(g) for carbon adsorbers and in Sec.
63.750(h) for control devices other than carbon adsorbers. For carbon
adsorbers, the initial performance test shall be used to establish the
appropriate rolling material balance period for determining compliance.
The procedures in paragraphs (2)(i) through (2)(vi) of this section
shall be used in determining initial compliance with the provisions of
this subpart for carbon adsorbers.
(i)(A) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with a common exhaust stack for all the individual carbon
adsorber vessels pursuant to Sec. 63.750(g)(2) or (4), the test shall
consist of three separate runs, each coinciding with one or more
complete sequences through the adsorption cycles of all of the
individual carbon adsorber vessels.
(B) When either EPA Method 18 or EPA Method 25A is to be used in the
determination of the efficiency of a fixed-bed carbon adsorption system
with individual exhaust stacks for each carbon adsorber vessel pursuant
to Sec. 63.750(g) (3) or (4), each carbon adsorber vessel shall be
tested individually. The test for each carbon adsorber vessel shall
consist of three separate runs. Each run shall coincide with one or more
complete adsorption cycles.
(ii) EPA Method 1 or 1A of appendix A of part 60 is used for sample
and velocity traverses.
(iii) EPA Method 2, 2A, 2C, or 2D of appendix A of part 60 is used

(3) An organic HAP-containing chemical stripper depainting operation
is considered in compliance when the conditions specified in paragraph
(g)(3)(i) of this section are met.
(i) If a carbon adsorber (or other control device) is used, the
overall control efficiency of the control system, as determined using
the procedures specified in Sec. 63.750(g) (or other control device as
determined using the procedures specified in Sec. 63.750(h)), is equal
to or greater than 81% for control systems installed before the
effective date, or equal to or greater than 95% for control systems
installed on or after the effective date, during the initial performance
test and all subsequent material balances (or performance tests, as
appropriate).
(ii) For non-HAP depainting operations complying with Sec.
63.746(b)(1);
(A) For any spot stripping and decal removal, the value of C, as
determined using the procedures specified in Sec. 63.750(j), is less
than or equal to 26 gallons of organic HAP-containing chemical stripper
or 190 pounds of organic HAP per commercial aircraft
[[Page 279]]
depainted calculated on a yearly average; and is less than or equal to
50 gallons of organic HAP-containing chemical stripper or 365 pounds of
organic HAP per military aircraft depainted calculated on a yearly
average; and
(B) The requirements of Sec. 63.746(b)(2) are carried out during
malfunctions of non-chemical based equipment.
(g) Inorganic HAP emissions--depainting operations. Each depainting
operation is in compliance when:
(1) The operating requirements specified in Sec. 63.746(b)(4) are
followed; and
(2) It is shut down immediately whenever the pressure drop or water
flow rate is outside the limit(s) established for them and is not
restarted until the pressure drop or water flow rate is returned within
these limit(s), as required under Sec. 63.746(b)(4)(v).
(h) Chemical milling maskant application operations--(1) Performance
test periods. For uncontrolled chemical milling maskants that are not
averaged, each 24-hour period is considered a performance test. For
compliant and noncompliant chemical milling maskants that are averaged
together, each 30-day period is considered a performance test, unless
the permitting agency specifies a shorter period as part of an ambient
ozone control program. When using a control device other than a carbon
adsorber, three 1-hour runs constitute the test period for the initial
and any subsequent performance test. When a carbon adsorber is used,
each rolling material balance period is considered a performance test.
(2) Initial performance tests. If a control device is used, each
owner or operator shall conduct an initial performance test to
demonstrate compliance with the overall reduction efficiency specified
in Sec. 63.747(d), unless a waiver is obtained under either Sec.
63.7(e)(2)(iv) or Sec. 63.7(h). The initial performance test shall be
conducted according to the procedures and test methods specified in
Sec. 63.7 and Sec. 63.750(g) for carbon adsorbers and in Sec.
63.750(h) for control devices other than carbon adsorbers. For carbon
adsorbers, the initial performance test shall be used to establish the
appropriate rolling material balance period for determining compliance.
The procedures in paragraphs (h)(2) (i) through (vi) of this section
shall be used in determining initial compliance with the provisions of
this subpart for carbon adsorbers.
(i)(A) When either EPA Method 18 or EPA Method 25A is to be used in
the determination of the efficiency of a fixed-bed carbon adsorption
system with a common exhaust stack for all the individual carbon
adsorber vessels pursuant to Sec. 63.750(g) (2) or (4), the test shall
consist of three separate runs, each coinciding with one or more
complete sequences through the adsorption cycles of all of the
individual carbon adsorber vessels.
(B) When either EPA Method 18 or EPA Method 25A is to be used in the
determination of the efficiency of a fixed-bed carbon adsorption system
with individual exhaust stacks for each carbon adsorber vessel pursuant
to Sec. 63.750(g) (3) or (4), each carbon adsorber vessel shall be
tested individually. The test for each carbon adsorber vessel shall
consist of three separate runs. Each run shall coincide with one or more
complete adsorption cycles.
(ii) EPA Method 1 or 1A of appendix A of part 60 is used for sample
and velocity traverses.
(iii) EPA Method 2, 2A, 2C, or 2D of appendix A of part 60 is used
for velocity and volumetric flow rates.
(iv) EPA Method 3 of appendix A of part 60 is used for gas analysis.
(v) EPA Method 4 of appendix A of part 60 is used for stack gas
moisture.
(vi) EPA Methods 2, 2A, 2C, 2D, 3, and 4 shall be performed, as
applicable, at least twice during each test period.
(3) The chemical milling maskant application operation is considered
in compliance when the conditions specified in paragraphs (i)(3)(i) and
(ii) of this section are met. The compliance demonstration for a
chemical milling maskant may be based on the organic HAP content or the
VOC content of the chemical milling maskant; demonstrating compliance
with both the HAP content limit and the VOC content limit is not
required. If a chemical milling maskant contains HAP solvents that are
exempt from the definition of VOC in Sec. 63.741 and 40 CFR 51.100,
then the HAP content must be used to demonstrate compliance.
[[Page 280]]
(i) For all uncontrolled chemical milling maskants, all values of
Hi and Ha (as determined using the procedures
specified in Sec. 63.750 (k) and (l)) are less than or equal to 622
grams of organic HAP per liter (5.2 lb/gal) of Type I chemical milling
maskant as applied (less water), and 160 grams of organic HAP per liter
(1.3 lb/gal) of Type II chemical milling maskant as applied (less
water). All values of Gi and Ga (as determined
using the procedures specified in Sec. 63.750 (m) and (n)) are less
than or equal to 622 grams of VOC per liter (5.2 lb/gal) of Type I
chemical milling maskant as applied (less water and exempt solvents),
and 160 grams of VOC per liter (1.3 lb/gal) of Type II chemical milling
maskant (less water and exempt solvents) as applied.
(ii) If a carbon adsorber (or other control device) is used, the
overall control efficiency of the control system, as determined using
the procedures specified in Sec. 63.750(g) (or systems with other
control devices as determined using the procedures specified in Sec.
63.750(h)), is equal to or greater than 81% during the initial
performance test period and all subsequent material balances (or
performance tests, as appropriate).
(i) Handling and storage of waste. For those wastes subject to this
subpart, failure to comply with the requirements specified in Sec.
63.748 shall be considered a violation.
(j) Performance tests shall be conducted under such conditions as
the Administrator specifies to the owner or operator based on
representative performance of the affected source for the period being
tested. Representative conditions exclude periods of startup and
shutdown unless specified by the Administrator or an applicable subpart.
The owner or operator may not conduct performance tests during periods
of malfunction. The owner or operator must record the process
information that is necessary to document operating conditions during
the test and include in such record an explanation to support that such
conditions represent normal operation. Upon request, the owner or
operator shall make available to the Administrator such records as may
be necessary to determine the conditions of performance tests.

Sec. 63.750 Test methods and procedures.
(a) Composition determination. Compliance with the hand-wipe
cleaning solvent approved composition list specified in Sec.
63.744(b)(1) for hand-wipe cleaning solvents shall be demonstrated using
data supplied by the manufacturer of the cleaning solvent. The data
shall identify all components of the cleaning solvent and shall
demonstrate that one of the approved composition definitions is met.
(b) Vapor pressure determination. The composite vapor pressure of
hand-wipe cleaning solvents used in a cleaning operation subject to this
subpart shall be determined as follows:
(1) For single-component hand-wipe cleaning solvents, the vapor
pressure shall be determined using MSDS or other manufacturer's data,
standard engineering reference texts, or other equivalent methods.
(2) The composite vapor pressure of a blended hand-wipe solvent
shall be determined by quantifying the amount of each organic compound
in the blend using manufacturer's supplied data or a gas chromatographic
analysis in accordance with ASTM E 260-91 or 96 (incorporated by
reference--see Sec. 63.14 of subpart A of this part) and by calculating
the composite vapor pressure of the solvent by summing the partial
pressures of each component. The vapor pressure of each component shall
be determined using manufacturer's data, standard engineering reference
texts, or other equivalent methods. The following equation shall be used
to determine the composite vapor pressure:
[GRAPHIC] [TIFF OMITTED] TR01SE98.000
where:
Wi = Weight of the ``i''th VOC compound, grams.
Ww = Weight of water, grams.
[[Page 281]]
We = Weight of non-HAP, nonVOC compound, grams.
MWi = Molecular weight of the ``i''th VOC compound, g/g-mole.
MWw = Molecular weight of water, g/g-mole.
MWe = Molecular weight of exempt compound, g/g-mole.
PPc = VOC composite partial pressure at 20 [deg]C, mm Hg.
VPi = Vapor pressure of the ``i''th VOC compound at 20
[deg]C, mm Hg.
(c) Organic HAP content level determination--compliant primers,
topcoats, and specialty coatings. For those uncontrolled primers,
topcoats, and specialty coatings complying with the primer, topcoat, or
specialty coating organic HAP content limits specified in Sec.
63.745(c) without being averaged, the procedures in paragraphs (c)(1)
through (3) of this section shall be used to determine the mass of
organic HAP emitted per volume of coating (less water) as applied. As an
alternative to the procedures in paragraphs (c)(1) through (3) of this
section, an owner or operator may use the coating manufacturer's
supplied data to demonstrate that organic HAP emitted per volume of
coating (less water), as applied, is less than or equal to the
applicable organic HAP limit specified in Sec. 63.745(c). Owners and
operators that use the coating manufacturer's supplied data to
demonstrate compliance based on the HAP content of the coating may add
non-HAP solvent to those coatings provided that the owner or operator
also maintains records of the non-HAP solvent added to the coating.
(1) For coatings that contain no exempt solvents, determine the
total organic HAP content using manufacturer's supplied data or Method
24 of 40 CFR part 60, appendix A, to determine the VOC content. The VOC
content shall be used as a surrogate for total HAP content for coatings
that contain no exempt solvent. If there is a discrepancy between the
manufacturer's formulation data and the results of the Method 24
analysis, compliance shall be based on the results from the Method 24
analysis.
When Method 24 is used to determine the VOC content of water-
reducible coatings, the precision adjustment factors in Reference Method
24 shall be used. If the adjusted analytical VOC content is less than
the formulation solvent content, then the analytical VOC content should
be set equal to the formulation solvent content.
(2) For each coating formulation as applied, determine the organic
HAP weight fraction, water weight fraction (if applicable), and density
from manufacturer's data. If the value for organic HAP weight fraction
cannot be determined using the manufacturer's data, the owner or
operator shall use Method 311 of 40 CFR part 63, appendix A, or submit
an alternative procedure for determining the value for approval by the
Administrator. If the values for water weight fraction (if applicable)
and density cannot be determined using the manufacturer's data, the
owner or operator shall submit an alternative procedure for determining
their values for approval by the Administrator. Recalculation is
required only when a change occurs in the coating formulation. If there
is a discrepancy between the manufacturer's formulation data and the
results of the Method 311 analysis, compliance shall be based on the
results from the Method 311 analysis.
(3) For each coating as applied, calculate the mass of organic HAP
emitted per volume of coating (lb/gal) less water as applied using
equations 1, 2, and 3:
[GRAPHIC] [TIFF OMITTED] TR01SE95.004
where:
Vwi = volume (gal) of water in one gal of coating i.
Dci = density (lb of coating per gal of coating) of coating
i.
Wwi = weight fraction (expressed as a decimal) of water in
coating i.

[GRAPHIC] [TIFF OMITTED] TR01SE95.005
where:
MHi = mass (lb) of organic HAP in one gal of coating i.
Dci = density (lb of coating per gal of coating) of coating
i.
WHi = weight fraction (expressed as a decimal) of organic HAP
in coating i.
[GRAPHIC] [TIFF OMITTED] TR01SE95.006
where:
[[Page 282]]
Hi = mass of organic HAP emitted per volume of coating i (lb/
gal) less water as applied.
MHi = mass (lb) of organic HAP in one gal of coating i.
Vwi = volume (gal) of water in one gal of coating i.
(d) Organic HAP content level determination--averaged primers,
topcoats, and specialty coatings. For those uncontrolled primers,
topcoats, and specialty coatings that are averaged together in order to
comply with the primer, topcoat, and specialty coating organic HAP
content limits specified in Sec. 63.745(c), the following procedure
shall be used to determine the monthly volume-weighted average mass of
organic HAP emitted per volume of coating (less water) as applied,
unless the permitting agency specifies a shorter averaging period as
part of an ambient ozone control program.
(1)(i) Determine the total organic HAP weight fraction as applied of
each coating. If any ingredients, including diluent solvent, are added
to a coating prior to its application, the organic HAP weight fraction
of the coating shall be determined at a time and location in the process
after all ingredients have been added.
(ii) Determine the total organic HAP weight fraction of each coating
as applied each month.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the organic HAP content of the coating, the value previously determined
may continue to be used until a change in formulation has been made by
either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the organic HAP content of the coating, the total
organic HAP weight fraction of the coating shall be redetermined.
(iii) Manufacturer's formulation data may be used to determine the
total organic HAP content of each coating and any ingredients added to
the coating prior to its application. If the total organic HAP content
cannot be determined using the manufacturer's data, the owner or
operator shall use Method 311 of 40 CFR part 63, appendix A for
determining the total organic HAP weight fraction, or shall submit an
alternative procedure for determining the total organic HAP weight
fraction for approval by the Administrator. If there is a discrepancy
between the manufacturer's formulation data and the results of the
Method 311 analysis, compliance shall be based on the results from the
Method 311 analysis.
(2)(i) Determine the volume both in total gallons as applied and in
total gallons (less water) as applied of each coating. If any
ingredients, including diluent solvents, are added prior to its
application, the volume of each coating shall be determined at a time
and location in the process after all ingredients (including any diluent
solvent) have been added.
(ii) Determine the volume of each coating (less water) as applied
each month, unless the permitting agency specifies a shorter period as
part of an ambient ozone control program.
(iii) The volume applied may be determined from company records.
(3)(i) Determine the density of each coating as applied. If any
ingredients, including diluent solvent, are added to a coating prior to
its application, the density of the coating shall be determined at a
time and location in the process after all ingredients have been added.
(ii) Determine the density of each coating as applied each month,
unless the permitting agency specifies a shorter period as part of an
ambient ozone control program.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the density of the coating, then the value previously determined may
continue to be used until a change in formulation has been made by
either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the density of the coating, then the density of
the coating shall be redetermined.
[[Page 283]]
(iii) The density may be determined from company records, including
manufacturer's data sheets. If the density of the coating cannot be
determined using the company's records, including the manufacturer's
data, then the owner or operator shall submit an alternative procedure
for determining the density for approval by the Administrator.
(4) Calculate the total volume in gallons as applied (less water) by
summing the individual volumes of each coating (less water) as applied,
which were determined under paragraph (d)(2) of this section.
(5) Calculate the volume-weighted average mass of organic HAP in
coatings emitted per unit volume (lb/gal) of coating (less water) as
applied during each 30-day period using equation 4:
[GRAPHIC] [TIFF OMITTED] TR01SE95.007
where:
Ha = volume-weighted average mass of organic HAP emitted per
unit volume of coating (lb/gal) (less water) as applied during
each 30-day period for those coatings being averaged.
n = number of coatings being averaged.
WHi = weight fraction (expressed as a decimal) of organic HAP
in coating i as applied that is being averaged during each 30-
day period.
Dci = density (lb of coating per gal of coating) of coating i
as applied that is being averaged during each 30-day period.
Vci = volume (gal) of coating i as applied that is being
averaged during the 30-day period.
Clw = total volume (gal) of all coatings (less water) as
applied that are being averaged during each 30-day period.
(e) VOC content level determination--compliant primers, topcoats,
and specialty coatings. For those uncontrolled primers, topcoats, and
specialty coatings complying with the primer, topcoat, and specialty
coating VOC content levels specified in Sec. 63.745(c) without being
averaged, the procedures in paragraphs (e)(1) through (3) of this
section shall be used to determine the mass of VOC emitted per volume of
coating (less water and exempt solvents) as applied. As an alternative
to the procedures in paragraphs (e)(1) through (3) of this section, an
owner or operator may use coating manufacturer's supplied data to
demonstrate that VOC emitted per volume of coating (less water and
exempt solvents), as applied, is less than or equal to the applicable
VOC limit specified in Sec. 63.745(c).
(1) Determine the VOC content of each formulation (less water and
exempt solvents) as applied using manufacturer's supplied data or Method
24 of 40 CFR part 60, appendix A, to determine the VOC content. The VOC
content shall be used as a surrogate for total HAP content for coatings
that contain no exempt solvent. If there is a discrepancy between the
manufacturer's formulation data and the results of the Method 24
analysis, compliance shall be based on the results from the Method 24
analysis.
When Method 24 is used to determine the VOC content of water-
reducible coatings, the precision adjustment factors in Reference Method
24 shall be used. If the adjusted analytical VOC content is less than
the formulation solvent content, then the analytical VOC content should
be set equal to the formulation solvent content.
(2) For each coating applied, calculate the mass of VOC emitted per
volume of coating (lb/gal) (less water and exempt solvents) as applied
using equations 5, 6, and 7:
[GRAPHIC] [TIFF OMITTED] TR01SE95.008
where:
Vwi = volume (gal) of water in one gal of coating i.
Dci = density (lb of coating per gal of coating) of coating
i.
Wwi = weight fraction (expressed as a decimal) of water in
coating i.
Dw = density of water, 8.33 lb/gal.
[GRAPHIC] [TIFF OMITTED] TR01SE95.009
where:
MVi = mass (lb) of VOC in one gal of coating i.
Dci = density (lb of coating per gal of coating) of coating
i.
WVi = weight fraction (expressed as a decimal) of VOC in
coating i.
[[Page 284]]
[GRAPHIC] [TIFF OMITTED] TR27MR98.002
where:
Gi = mass of VOC emitted per volume of coating i (lb/gal)
(less water and exempt solvents) as applied.
MVi = mass (lb) of VOC in one gal of coating i.
Vwi = volume (gal) of water in one gal of coating i.
VXi = volume (gal) of exempt solvents in one gal of coating
i.
(3)(i) If the VOC content is found to be different when EPA Method
24 is used during an enforcement inspection from that used by the owner
or operator in calculating Ga, compliance shall be based,
except as provided in paragraph (e)(3)(ii) of this section, upon the VOC
content obtained using EPA Method 24.
(ii) If the VOC content of a coating obtained using Method 24 would
indicate noncompliance as determined under either Sec. 63.749 (d)(3)(i)
or (d)(4)(i), an owner or operator may elect to average the coating with
other uncontrolled coatings and (re)calculate Gi (using the
procedure specified in paragraph (f) of this section), provided
appropriate and sufficient records were maintained for all coatings
included in the average (re)calculation. The (re)calculated value of
Gi (Ga in paragraph (f)) for the averaged coatings
shall then be used to determine compliance.
(f) VOC content level determination--averaged primers, topcoats, and
specialty coatings. For those uncontrolled primers, topcoats, and
specialty coatings that are averaged within their respective coating
category in order to comply with the primer, topcoat, and specialty
coating VOC content limits specified in Sec. 63.745(c)(2), (c)(4), and
(c)(6), the following procedure shall be used to determine the monthly
volume-weighted average mass of VOC emitted per volume of coating (less
water and exempt solvents) as applied, unless the permitting agency
specifies a shorter averaging period as part of an ambient ozone control
program.
(1)(i) Determine the VOC content (lb/gal) as applied of each
coating. If any ingredients, including diluent solvent, are added to a
coating prior to its application, the VOC content of the coating shall
be determined at a time and location in the process after all
ingredients have been added.
(ii) Determine the VOC content of each coating as applied each
month, unless the permitting agency specifies a shorter period as part
of an ambient ozone control program.
(A) If no changes have been made to a coating, either as supplied or
as applied, or if a change has been made that has a minimal effect on
the VOC content of the coating, the value previously determined may
continue to be used until a change in formulation has been made by
either the manufacturer or the user.
(B) If a change in formulation or a change in the ingredients added
to the coating takes place, including the ratio of coating to diluent
solvent, prior to its application, either of which results in a more
than minimal effect on the VOC content of the coating, the VOC content
of the coating shall be redetermined.
(iii) Determine the VOC content of each primer, topcoat, and
specialty coating formulation (less water and exempt solvents) as
applied using EPA Method 24 or from manufacturer's data.
(2)(i) Determine the volume both in total gallons as applied and in

coating. If any ingredients, including diluent solvents, are added prior
to its application, the volume of each coating shall be determined at a
time and location in the process after all ingredients (including any
diluent solvent) have been added.
(ii) Determine the volume of each coating (less water and exempt
solvents) as applied each day.
(iii) The volume applied may be determined from company records.
(3) Calculate the total volume in gallons (less water and exempt
solvents) as applied by summing the individual volumes of each coating
(less water and exempt solvents) as applied, which were determined under
paragraph (f)(2) of this section.
(4) Calculate the volume-weighted average mass of VOC emitted per
unit volume (lb/gal) of coating (less water and exempt solvents) as
applied for
[[Page 285]]
each coating category during each 30-day period using equation 8:
[GRAPHIC] [TIFF OMITTED] TR01SE95.011

or operator in calculating Ga, recalculation of Ga
is required using the new value. If more than one coating is involved,
the recalculation shall be made once using all of the new values.
(ii) If recalculation is required, an owner or operator may elect to
include in the recalculation of Ga uncontrolled coatings that
were not previously included provided appropriate and sufficient records
were maintained for these other coatings to allow daily recalculations.
(iii) The recalculated value of Ga under either paragraph
(f)(5)(i) or (f)(5)(ii) of this section shall be used to determine
compliance.

63.745(d), Sec. 63.746(c), or Sec. 63.747(d) shall demonstrate initial
compliance with the requirements of this subpart by following the
procedures of paragraph (g)(1), (2), (3), (4), or (5) as applicable and

capturing, venting, and measuring all HAP emissions from the HAP
emission points. During a performance test, the owner or operator of
affected HAP emission points located in an area with other gaseous
emission sources not affected by this subpart shall isolate the affected
HAP emission points from all other gaseous emission points by one of the
following methods:
(A) Build a temporary total enclosure around the affected HAP
emission point(s); or
(B) Shut down all gaseous emission points not affected by this
subpart and continue to exhaust fugitive emissions from the affected HAP
emission points through any building ventilation system and other room
exhausts such as drying ovens. All ventilation air must be vented
through stacks suitable for testing.
(iii) Operate the emission control device with all affected HAP
emission points connected and operating.
(iv) Determine the efficiency (E) of the control device using
equation 10:
(v) Determine the efficiency (F) of the capture system using

[GRAPHIC] [TIFF OMITTED] TR01SE95.013
(vi) For each HAP emission point subject to Sec. 63.745(d), Sec.
63.746(c), or Sec. 63.747(d), compliance is demonstrated if the product
of (E) x (F) is equal to or greater than the overall HAP control
efficiencies required under Sec. 63.745(d), Sec. 63.746(c), or Sec.
63.747(d).

or Sec. 63.747(d) when affected HAP emission points are controlled by a
fixed-bed carbon adsorption system with individual exhaust stacks for
each carbon adsorber vessel, each owner or operator of an affected
source shall perform a gaseous emission test using the following
procedures:
(i) Construct the overall HAP emission reduction system so that each
volumetric flow rate and the total HAP emissions can be accurately
determined by the applicable test methods and procedures specified in
Sec. 63.750(g) (9) through (14);
(ii) Assure that all HAP emissions from the affected HAP emission
point(s) are segregated from gaseous emission points not affected by
this
[[Page 287]]
subpart and that the emissions can be captured for measurement, as

of (Hsys) x (F) is equal to or greater than the overall HAP
control efficiency required by Sec. 63.745(d), Sec. 63.746(c), or
Sec. 63.747(d).
(4) An alternative method of demonstrating compliance with Sec.
63.745(d), Sec. 63.746(c), or Sec. 63.747(d) is the installation of a
total enclosure around the affected HAP emission point(s) and the
ventilation of all HAP emissions from the total enclosure to a control
device with the efficiency specified in paragraph (g)(4)(iii) of this
section. If this method is selected, the compliance test methods
described in paragraphs (g)(1), (g)(2), and (g)(3) of this section are
not required. Instead, each owner or operator of an affected source
shall:
(i) Demonstrate that a total enclosure is installed. An enclosure
that meets the requirements in paragraphs (g)(4)(i) (A) through (D) of
this section shall be considered a total enclosure. The owner or
operator of an enclosure that does not meet these requirements may apply
to the Administrator for approval of the enclosure as a total enclosure
on a case-by-case basis. The enclosure shall be considered a total
enclosure if it is demonstrated to the satisfaction of the Administrator
that all HAP emissions from the affected HAP emission point(s) are
contained and vented to the control device. The requirements for
automatic approval are as follows:
(A) The total area of all natural draft openings shall not exceed 5%
of the total surface area of the total enclosure's walls, floor, and
ceiling;
(B) All sources of emissions within the enclosure shall be a minimum
of four equivalent diameters away from each natural draft opening;
(C) The average inward face velocity (FV) across all natural draft
openings shall be a minimum of 3,600 meters per hour as determined by

(1) All forced makeup air ducts and all exhaust ducts are
constructed so that the volumetric flow rate in each can be accurately
determined by the test methods and procedures specified in Sec.
63.750(g) (10) and (11); volumetric flow rates shall be calculated
without the adjustment normally made for moisture content; and
(2) Determine FV by equation 14:
[GRAPHIC] [TIFF OMITTED] TR01SE95.016
(D) The air passing through all natural draft openings shall flow
into the enclosure continuously. If FV is less than or equal to 9,000
meters per hour, the continuous inward flow of air shall be verified by
continuous observation using smoke tubes, streamers, tracer gases, or
other means approved by the Administrator over the period that the
volumetric flow rate tests required to determine FV are carried out. If
FV is greater than 9,000 meters per hour, the direction of airflow
through the natural draft openings shall be presumed to be inward at all
times without verification.
[[Page 288]]
(ii) Determine the control device efficiency using equation 10 or
equations 12 and 13, as applicable, and the test methods and procedures
specified in Sec. 63.750(g) (9) through (14).
(iii) Compliance shall be achieved if the installation of a total
enclosure is demonstrated and the value of E determined from equation 10
(or the value of Hsys determined from equations 12 and 13, as
applicable) is equal to or greater than the overall HAP control
efficiencies required under Sec. 63.745(d), Sec. 63.746(c), or Sec.
63.747(d).
(5) When nonregenerative carbon adsorbers are used to comply with
Sec. 63.745(d), Sec. 63.746(c), or Sec. 63.747(d), the owner or
operator may conduct a design evaluation to demonstrate initial
compliance in lieu of following the compliance test procedures of
paragraphs (g)(1), (2), (3), and (4) of this section. The design
evaluation shall consider the vent stream composition, component
concentrations, flow rate, relative humidity, and temperature, and shall
establish the design exhaust vent stream organic compound concentration
level, capacity of the carbon bed, type and working capacity of
activated carbon used for the carbon bed, and design carbon replacement
interval based on the total carbon working capacity of the control
device and the emission point operating schedule.
(6)(i) To demonstrate initial compliance with Sec. 63.745(d), Sec.
63.746(c), or Sec. 63.747(d) when hard piping or ductwork is used to
direct VOC and HAP emissions from a VOC and HAP source to the control
device, each owner or operator shall demonstrate upon inspection that
the criteria of paragraph (g)(6)(i)(A) and paragraph (g)(6)(i) (B) or
(C) of this section VR/FD are met.

63.750(g) (9) through (14), shall be equal to or greater than the
overall HAP control efficiency required by Sec. 63.745(d), Sec.
63.746(c), or Sec. 63.747(d).

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

category. Emissions from these activities are to be included when
determining if the standards specified in Sec. 63.745(d), Sec.
63.746(c), or Sec. 63.747(d) are being attained.

the intended test method to the Administrator for approval along with
the notification of the performance test required under Sec. 63.7(b).
Method selection shall be based on consideration of the diversity of
organic species present and their total concentration and on
consideration of the potential presence of interfering gases. Except as
indicated in paragraphs (g)(9) (i) and (ii) of this section, the test
shall consist of three separate runs, each lasting a minimum of 30
minutes.
(i) When either EPA Method 18 or EPA Method 25A is to be used in the

application methods, or airless application methods shall comply with
the following:
(i) Each coating shall be applied such that the dried film thickness
is within the range specified by the applicable specification(s) for the
aerospace vehicle or component being coated.
(ii) If no such dried film thickness specification(s) exists, the
owner or operator shall ensure that the dried film thickness applied
during the initial 30-day period is equivalent to the dried film
thickness applied during the alternative application method test period
for similar aerospace vehicles or components.
(iii) Failure to comply with these dried film thickness requirements
shall invalidate the test results obtained under paragraph (i)(2)(i) of
this section.
(j) Spot stripping and decal removal. Each owner or operator seeking

HAP-containing chemical strippers or alternatively the weight of organic
HAP used per aircraft using the procedure specified in paragraphs (j)(1)
through (j)(3) of this section.
(1) For each chemical stripper used for spot stripping and decal
removal, determine for each annual period the total volume as applied or
the total weight of organic HAP using the procedure specified in
paragraph (d)(2) of this section.
(2) Determine the total number of aircraft for which depainting
operations began during the annual period as determined from company
records.
(3) Calculate the annual average volume of organic HAP-containing
chemical stripper or weight of organic HAP used for spot stripping and
decal removal per aircraft using equation 20 (volume) or equation 21
(weight):
[GRAPHIC] [TIFF OMITTED] TR27MR98.004

(k) Organic HAP content level determination--compliant chemical
milling maskants. For those uncontrolled chemical milling maskants
complying with the chemical milling maskant organic HAP content limit
specified in Sec. 63.747(c)(1) without being averaged, the procedure in
paragraph (k)(1) of this section shall be used to determine the mass of
organic HAP emitted per unit volume of coating (chemical milling
maskant) i as applied (less water), Hi (lb/gal). As an
alternative to the procedures in paragraph (k)(1) of this section, an
owner or operator may use coating manufacturer's supplied data to
demonstrate that organic HAP emitted per volume of coating (less water),
as applied, is less than or equal to the applicable organic HAP limit
specified in Sec. 63.747(c). Owners and operators that use the coating
manufacturer's supplied data to demonstrate compliance based on the HAP
content of the coating may add non-HAP solvent to those coatings
provided that the owner or operator also maintains records of the non-
HAP solvent added to the coating.
(1) For coatings that contain no exempt solvents, determine the
total organic HAP content using manufacturer's supplied data or Method
24 of 40 CFR part 60, appendix A to determine the VOC content. The VOC
content shall be used as a surrogate for total HAP content for coatings
that contain no exempt solvent. If there is a discrepancy between the
manufacturer's formulation data and the results of the Method 24
analysis, compliance shall be based on the results from the Method 24
analysis.
When Method 24 is used to determine the VOC content of water-
reducible coatings, the precision adjustment factors in Reference Method
24 shall be used. If the adjusted analytical VOC content is less than
the formulation solvent content, then the analytical VOC content should
be set equal to the formulation solvent content.
(2) [Reserved]
(l) Organic HAP content level determination--averaged chemical
milling maskants. For those uncontrolled chemical milling maskants that
are averaged together in order to comply with the chemical milling
maskant organic HAP content level specified in Sec. 63.747(c)(1), the
procedure specified in paragraphs (l)(1) through (l)(4) of this section

organic HAP emitted per volume of chemical milling maskant (less water)
as applied, unless the permitting agency specifies a shorter averaging
period as part of an ambient ozone control program.
(1) Determine the total organic HAP weight fraction as applied of
each chemical milling maskant used during each 30-day period using the
procedure specified in paragraph (d)(1) of this section.
(2) Determine for each 30-day period:

paragraph (d)(2) of this section), and
(ii) The total volume in gallons of all chemical milling maskants
(less water) as applied by summing the individual volumes of each

paragraphs (m)(1) and (2) of this section shall be used to determine the
mass of VOC emitted per volume of chemical milling maskant (less water
and exempt solvents) as applied. As an alternative to the procedures in
paragraphs (m)(1) and (2) of this section, an owner or operator may use
coating manufacturer's supplied data to demonstrate that VOC emitted per
volume of coating (less water and exempt solvents), as applied, is less
than or equal to the applicable VOC limit specified in Sec. 63.747(c).
(1) Determine the mass of VOC emitted per unit volume of chemical
milling maskant (lb/gal) (less water and exempt solvents) as applied,

specified in paragraphs (e)(1) and (e)(2) of this section.
(2)(i) If the VOC content is found to be different when EPA Method
24 is used during an enforcement inspection from that used by the owner
or operator in calculating Gi, compliance shall be based,
except as provided in paragraph (m)(2)(ii) of this section, upon the VOC
content obtained using EPA Method 24.
(ii) If the VOC content of a chemical milling maskant obtained using
EPA Method 24 would indicate noncompliance as determined under Sec.
63.749(h)(3)(i), an owner or operator may elect to average the chemical
milling maskant with other uncontrolled chemical milling maskants and
(re)calculate Ga (using the procedure specified in paragraph
(n) of this section), provided appropriate and sufficient records were
maintained for all chemical milling maskants included in the average
recalculation. The (re)calculated value of Ga for the
averaged chemical milling maskants shall then be used to determine
compliance.
(n) VOC content level determination--averaged chemical milling
maskants. For those uncontrolled chemical milling maskants that are
averaged together in order to comply with the chemical milling maskant
VOC content limit specified in Sec. 63.747(c)(2), the procedure
specified in paragraphs (n)(1) through (n)(4) of this section shall be

[GRAPHIC] [TIFF OMITTED] TR27MR98.007
where:
[[Page 294]]
Ga = volume-weighted average mass of VOC per unit volume of
chemical milling maskant (lb/gal) (less water and exempt
solvents) as applied during each 30-day period for those
chemical milling maskants that are averaged.
n = number of chemical milling maskants being averaged.
(VOC)mi = VOC content (lb/gal) of chemical milling maskant i
(less water and exempt solvents) as applied during the 30-day
period that is averaged.
Vmi = volume (gal) of chemical milling maskant i (less water
and exempt solvents) as applied during the 30-day period that
is averaged.
Mlwes = total volume (gal) of all chemical milling maskants
(less water and exempt solvents) as applied during each 30-day
period that is averaged.
(4)(i) If the VOC content is found to be different when EPA Method
24 is used during an enforcement inspection from that used by the owner
or operator in calculating Ga, recalculation of Ga
is required using the new value. If more than one chemical milling
maskant is involved, the recalculation shall be made once using all of
the new values.
(ii) If recalculation is required, an owner or operator may elect to
include in the recalculation of Ga uncontrolled chemical
milling maskants that were not previously included provided appropriate
and sufficient records were maintained for these other chemical milling
maskants to allow daily recalculations.
(iii) The recalculated value of Ga under either paragraph
(n)(4)(i) or (n)(4)(ii) of this section shall be used to determine
compliance.
(o) Inorganic HAP emissions--dry particulate filter certification
requirements. Dry particulate filters used to comply with Sec. Sec.
63.745(g)(2) or 63.746(b)(4) must be certified by the filter
manufacturer or distributor, paint/depainting booth supplier, and/or the
facility owner or operator using method 319 in appendix A of this part,

Sec. Appendix A to Subpart GG of Part 63--Specialty Coating
Definitions
Ablative coating--A coating that chars when exposed to open flame or
extreme temperatures, as would occur during the failure of an engine
casing or during aerodynamic heating. The ablative char surface serves
as an insulative barrier, protecting adjacent components from the heat
or open flame.
Adhesion promoter--A very thin coating applied to a substrate to
promote wetting and form a chemical bond with the subsequently applied
material.
Adhesive bonding primer--A primer applied in a thin film to
aerospace components for the purpose of corrosion inhibition and
increased adhesive bond strength by attachment. There are two categories
of adhesive bonding primers: primers with a design cure at 250 [deg]F or
below and primers with a design cure above 250 [deg]F.
Aerosol coating--A hand-held, pressurized, nonrefillable container
that expels an adhesive or a coating in a finely divided spray when a
valve on the container is depressed.
Antichafe coating--A coating applied to areas of moving aerospace
components that may rub during normal operations or installation.
Bearing coating--A coating applied to an antifriction bearing, a
bearing housing, or the area adjacent to such a bearing in order to
facilitate bearing function or to protect base material from excessive
wear. A material shall not be classified as a bearing coating if it can
also be classified as a dry lubricative material or a solid film
lubricant.
Bonding maskant--A temporary coating used to protect selected areas
of aerospace parts from strong acid or alkaline solutions during
processing for bonding.
Caulking and smoothing compounds--Semi-solid materials which are
applied by hand application methods and are used to aerodynamically
smooth exterior vehicle surfaces or fill cavities such as bolt hole
accesses. A material shall not be classified as a caulking and smoothing
compound if it can also be classified as a sealant.
Chemical agent-resistant coating (CARC)--An exterior topcoat
designed to withstand exposure to chemical warfare agents or the
decontaminants used on these agents.
Clear coating--A transparent coating usually applied over a colored
opaque coating, metallic substrate, or placard to give improved gloss
and protection to the color coat. In some cases, a clearcoat refers to
any transparent coating without regard to substrate.
Commercial exterior aerodynamic structure primer--A primer used on
aerodynamic components and structures that protrude from the fuselage,
such as wings and attached components, control surfaces, horizontal
stabilizers, vertical fins, wing-to-body fairings, antennae, and landing
gear and doors, for the purpose of extended corrosion protection and
enhanced adhesion.
Commercial interior adhesive--Materials used in the bonding of
passenger cabin interior components. These components must meet the FAA
fireworthiness requirements.
Compatible substrate primer--Includes two categories: compatible
epoxy primer and adhesive primer. Compatible epoxy primer is primer that
is compatible with the filled elastomeric coating and is epoxy based.
The compatible substrate primer is an epoxy-polyamide primer used to
promote adhesion of elastomeric coatings such as impact-resistant
coatings. Adhesive primer is a coating that (1) inhibits corrosion and
serves as a primer applied to bare metal surfaces or prior to adhesive
application, or (2) is applied to surfaces that can be expected to
contain fuel. Fuel tank coatings are excluded from this category.
Corrosion prevention system--A coating system that provides
corrosion protection by displacing water and penetrating mating
surfaces, forming a protective barrier between the metal surface and
moisture. Coatings containing oils or waxes are excluded from this
category.
Critical use and line sealer maskant--A temporary coating, not
covered under other maskant categories, used to protect selected areas
of aerospace parts from strong acid or alkaline solutions such as those
used in anodizing, plating, chemical milling and processing of
magnesium, titanium, high-strength steel, high-precision aluminum
chemical milling of deep cuts, and aluminum chemical milling of complex
shapes. Materials used for repairs or to bridge gaps left by scribing
operations (i.e. line sealer) are also included in this category.
Cryogenic flexible primer--A primer designed to provide corrosion
resistance, flexibility, and adhesion of subsequent coating systems when
exposed to loads up to and surpassing the yield point of the substrate
at cryogenic temperatures (-275 [deg]F and below).
Cryoprotective coating--A coating that insulates cryogenic or
subcooled surfaces to limit propellant boil-off, maintain structural
integrity of metallic structures during ascent or re-entry, and prevent
ice formation.
Cyanoacrylate adhesive--A fast-setting, single component adhesive
that cures at room temperature. Also known as ``super glue.''
Dry lubricative material--A coating consisting of lauric acid, cetyl
alcohol, waxes, or other non-cross linked or resin-bound materials which
act as a dry lubricant.
Electric or radiation-effect coating--A coating or coating system
engineered to interact, through absorption or reflection, with specific
regions of the electromagnetic energy spectrum, such as the ultraviolet,
visible, infrared, or microwave regions. Uses include,
[[Page 311]]
but are not limited to, lightning strike protection, electromagnetic
pulse (EMP) protection, and radar avoidance. Coatings that have been
designated as ``Classified National Security Information'' by the
Department of Defense are exempt.
Electrostatic discharge and electromagnetic interference (EMI)
coating--A coating applied to aerospace vehicles and components to
disperse static energy or reduce electromagnetic interference.
Elevated-temperature Skydrol-resistant commercial primer--A primer
applied primarily to commercial aircraft (or commercial aircraft adapted
for military use) that must withstand immersion in phosphate-ester (PE)
hydraulic fluid (Skydrol 500b or equivalent) at the elevated temperature
of 150 [deg]F for 1,000 hours.
Epoxy polyamide topcoat--A coating used where harder films are
required or in some areas where engraving is accomplished in camouflage
colors.
Fire-resistant (interior) coating--For civilian aircraft, fire-
resistant interior coatings are used on passenger cabin interior parts
that are subject to the FAA fireworthiness requirements. For military
aircraft, fire-resistant interior coatings are used on parts subject to
the flammability requirements of MIL-STD-1630A and MIL-A-87721. For
space applications, these coatings are used on parts subject to the
flammability requirements of SE-R-0006 and SSP 30233.
Flexible primer--A primer that meets flexibility requirements such
as those needed for adhesive bond primed fastener heads or on surfaces
expected to contain fuel. The flexible coating is required because it
provides a compatible, flexible substrate over bonded sheet rubber and
rubber-type coatings as well as a flexible bridge between the fasteners,
skin, and skin-to-skin joints on outer aircraft skins. This flexible
bridge allows more topcoat flexibility around fasteners and decreases
the chance of the topcoat cracking around the fasteners. The result is
better corrosion resistance.
Flight test coating--A coating applied to aircraft other than
missiles or single-use aircraft prior to flight testing to protect the
aircraft from corrosion and to provide required marking during flight
test evaluation.
Fuel tank adhesive--An adhesive used to bond components exposed to
fuel and that must be compatible with fuel tank coatings.
Fuel tank coating--A coating applied to fuel tank components to
inhibit corrosion and/or bacterial growth and to assure sealant adhesion
in extreme environmental conditions.
High temperature coating--A coating designed to withstand
temperatures of more than 350 [deg]F.
Insulation covering--Material that is applied to foam insulation to
protect the insulation from mechanical or environmental damage.
Intermediate release coating--A thin coating applied beneath
topcoats to assist in removing the topcoat in depainting operations and
generally to allow the use of less hazardous depainting methods.
Lacquer--A clear or pigmented coating formulated with a
nitrocellulose or synthetic resin to dry by evaporation without a
chemical reaction. Lacquers are resoluble in their original solvent.
Metalized epoxy coating--A coating that contains relatively large
quantities of metallic pigmentation for appearance and/or added
protection.
Mold release--A coating applied to a mold surface to prevent the
molded piece from sticking to the mold as it is removed.
Nonstructural adhesive--An adhesive that bonds nonload bearing
aerospace components in noncritical applications and is not covered in
any other specialty adhesive categories.
Optical anti-reflection coating--A coating with a low reflectance in
the infrared and visible wavelength ranges, which is used for anti-
reflection on or near optical and laser hardware.
Part marking coating--Coatings or inks used to make identifying
markings on materials, components, and/or assemblies. These markings may
be either permanent or temporary.
Pretreatment coating--An organic coating that contains at least 0.5
percent acids by weight and is applied directly to metal or composite
surfaces to provide surface etching, corrosion resistance, adhesion, and
ease of stripping.
Rain erosion-resistant coating--A coating or coating system used to
protect the leading edges of parts such as flaps, stabilizers, radomes,
engine inlet nacelles, etc. against erosion caused by rain impact during
flight.
Rocket motor bonding adhesive--An adhesive used in rocket motor
bonding applications.
Rocket motor nozzle coating--A catalyzed epoxy coating system used
in elevated temperature applications on rocket motor nozzles.
Rubber-based adhesive--Quick setting contact cements that provide a
strong, yet flexible, bond between two mating surfaces that may be of
dissimilar materials.
Scale inhibitor--A coating that is applied to the surface of a part
prior to thermal processing to inhibit the formation of scale.
Screen print ink--Inks used in screen printing processes during
fabrication of decorative laminates and decals.
Seal coat maskant--An overcoat applied over a maskant to improve
abrasion and chemical resistance during production operations.
Sealant--A material used to prevent the intrusion of water, fuel,
air, or other liquids or solids from certain areas of aerospace vehicles
or components. There are two categories
[[Page 312]]
of sealants: extrudable/rollable/brushable sealants and sprayable
sealants.
Silicone insulation material--Insulating material applied to
exterior metal surfaces for protection from high temperatures caused by
atmospheric friction or engine exhaust. These materials differ from
ablative coatings in that they are not ``sacrificial.''
Solid film lubricant--A very thin coating consisting of a binder
system containing as its chief pigment material one or more of the
following: molybdenum, graphite, polytetrafluoroethylene (PTFE), or
other solids that act as a dry lubricant between faying surfaces.
Specialized function coatings--Coatings that fulfill extremely
specific engineering requirements that are limited in application and
are characterized by low volume usage. This category excludes coatings
covered in other Specialty Coating categories.
Structural autoclavable adhesive--An adhesive used to bond load-
carrying aerospace components that is cured by heat and pressure in an
autoclave.
Structural nonautoclavable adhesive--An adhesive cured under ambient
conditions that is used to bond load-carrying aerospace components or
for other critical functions, such as nonstructural bonding in the
proximity of engines.
Temporary protective coating--A coating applied to provide scratch
or corrosion protection during manufacturing, storage, or
transportation. Two types include peelable protective coatings and
alkaline removable coatings. These materials are not intended to protect
against strong acid or alkaline solutions. Coatings that provide this
type of protection from chemical processing are not included in this
category.
Thermal control coating--Coatings formulated with specific thermal
conductive or radiative properties to permit temperature control of the
substrate.
Touch-up and Repair Coating--A coating used to cover minor coating
imperfections appearing after the main coating operation.
Wet fastener installation coating--A primer or sealant applied by

Subpart HH_National Emission Standards for Hazardous Air Pollutants From
Oil and Natural Gas Production Facilities
Source: 64 FR 32628, June 17, 1999, unless otherwise noted.
Sec. 63.760 Applicability and designation of affected source.
(a) This subpart applies to the owners and operators of the emission
points, specified in paragraph (b) of this section that are located at
oil and natural gas production facilities that meet the specified
criteria in paragraphs (a)(1) and either (a)(2) or (a)(3) of this
section.
(1) Facilities that are major or area sources of hazardous air
pollutants (HAP) as defined in Sec. 63.761. Emissions for major source
determination purposes can be estimated using the maximum natural gas or
hydrocarbon liquid throughput, as appropriate, calculated in paragraphs
(a)(1)(i) through (iii) of this section. As an alternative to
calculating the maximum natural gas or hydrocarbon liquid throughput,
the owner or operator of a new or existing source may use the facility's
design maximum natural gas or hydrocarbon liquid throughput to estimate
the maximum potential emissions. Other means to determine the facility's
major source status are allowed, provided the information is documented
and recorded to the Administrator's satisfaction in accordance with
Sec. 63.10(b)(3). A facility that is determined to be an area source,
but subsequently increases its emissions or its potential to emit above
the major source levels, and becomes a major source, must comply
thereafter with all provisions of this subpart applicable to a major
source starting on the applicable compliance date specified in paragraph
(f) of this section. Nothing in this paragraph is intended to preclude a
source from limiting its potential to emit through other appropriate
mechanisms that may be available through the permitting authority.
(i) If the owner or operator documents, to the Administrator's
satisfaction, a decline in annual natural gas or hydrocarbon liquid
throughput, as appropriate, each year for the 5 years prior to October
15, 2012, the owner or operator shall calculate the maximum natural gas
or hydrocarbon liquid throughput used to determine maximum potential
emissions according to the requirements specified in paragraph
(a)(1)(i)(A) of this section. In all
[[Page 313]]
other circumstances, the owner or operator shall calculate the maximum
throughput used to determine whether a facility is a major source in
accordance with the requirements specified in paragraph (a)(1)(i)(B) of
this section.
(A) The maximum natural gas or hydrocarbon liquid throughput is the
average of the annual natural gas or hydrocarbon liquid throughput for
the 3 years prior to October 15, 2012, multiplied by a factor of 1.2.
(B) The maximum natural gas or hydrocarbon liquid throughput is the
highest annual natural gas or hydrocarbon liquid throughput over the 5
years prior to October 15, 2012, multiplied by a factor of 1.2.
(ii) The owner or operator shall maintain records of the annual
facility natural gas or hydrocarbon liquid throughput each year and upon
request submit such records to the Administrator. If the facility annual
natural gas or hydrocarbon liquid throughput increases above the maximum
natural gas or hydrocarbon liquid throughput calculated in paragraph
(a)(1)(i)(A) or (a)(1)(i)(B) of this section, the maximum natural gas or
hydrocarbon liquid throughput must be recalculated using the higher
throughput multiplied by a factor of 1.2.
(iii) The owner or operator shall determine the maximum values for
other parameters used to calculate emissions as the maximum for the
period over which the maximum natural gas or hydrocarbon liquid
throughput is determined in accordance with paragraph (a)(1)(i)(A) or
(B) of this section. Parameters, other than glycol circulation rate,
shall be based on either highest measured values or annual average. For
estimating maximum potential emissions from glycol dehydration units,
the glycol circulation rate used in the calculation shall be the unit's
maximum rate under its physical and operational design consistent with
the definition of potential to emit in Sec. 63.2.
(2) Facilities that process, upgrade, or store hydrocarbon liquids.
(3) Facilities that process, upgrade, or store natural gas prior to
the point at which natural gas enters the natural gas transmission and
storage source category or is delivered to a final end user. For the
purposes of this subpart, natural gas enters the natural gas
transmission and storage source category after the natural gas
processing plant, when present. If no natural gas processing plant is
present, natural gas enters the natural gas transmission and storage
source category after the point of custody transfer.
(b) The affected sources for major sources are listed in paragraph
(b)(1) of this section and for area sources in paragraph (b)(2) of this
section.
(1) For major sources, the affected source shall comprise each
emission point located at a facility that meets the criteria specified
in paragraph (a) of this section and listed in paragraphs (b)(1)(i)
through (b)(1)(iv) of this section.
(i) Each glycol dehydration unit as specified in paragraphs
(b)(1)(i)(A) through (C) of this section.
(A) Each large glycol dehydration unit;
(B) Each small glycol dehydration unit for which construction
commenced on or before August 23, 2011, is an existing small glycol
dehydration unit; and
(C) Each small glycol dehydration unit for which construction
commenced after August 23, 2011, is a new small glycol dehydration unit.
(ii) Each storage vessel with the potential for flash emissions;
(iii) The group of all ancillary equipment, except compressors,
intended to operate in volatile hazardous air pollutant service (as
defined in Sec. 63.761), which are located at natural gas processing
plants; and
(iv) Compressors intended to operate in volatile hazardous air
pollutant service (as defined in Sec. 63.761), which are located at
natural gas processing plants.
(2) For area sources, the affected source includes each triethylene
glycol (TEG) dehydration unit located at a facility that meets the
criteria specified in paragraph (a) of this section.
(c) Any source that determines it is not a major source but has
actual emissions of 5 tons per year or more of a single HAP, or 12.5
tons per year or more of a combination of HAP (i.e., 50 percent of the
major source thresholds), shall update its major source determination
within 1 year of the prior
[[Page 314]]
determination or October 15, 2012, whichever is later, and each year
thereafter, using gas composition data measured during the preceding 12
months.
(d) The owner and operator of a facility that does not contain an
affected source as specified in paragraph (b) of this section are not
subject to the requirements of this subpart.
(e) Exemptions. The facilities listed in paragraphs (e)(1) and
(e)(2) of this section are exempt from the requirements of this subpart.
Records shall be maintained as required in Sec. 63.10(b)(3).
(1) A facility that exclusively processes, stores, or transfers
black oil (as defined in Sec. 63.761) is not subject to the
requirements of this subpart. For the purposes of this subpart, a black
oil facility that uses natural gas for fuel or generates gas from black
oil shall qualify for this exemption.
(2) A major source facility, prior to the point of custody transfer,
with a facility-wide actual annual average natural gas throughput less
than 18.4 thousand standard cubic meters per day and a facility-wide
actual annual average hydrocarbon liquid throughput less than 39,700
liters per day.
(f) The owner or operator of an affected major source shall achieve
compliance with the provisions of this subpart by the dates specified in
paragraphs (f)(1), (2), and (f)(7) through (9) of this section. The
owner or operator of an affected area source shall achieve compliance
with the provisions of this subpart by the dates specified in paragraphs
(f)(3) through (6) of this section.
(1) Except as specified in paragraphs (f)(7) through (9) of this
section, the owner or operator of an affected major source, the
construction or reconstruction of which commenced before February 6,
1998, shall achieve compliance with the applicable provisions of this

during malfunction.
(a) The provisions set forth in this subpart shall apply at all
times.
(b)-(c) [Reserved]
(d) In response to an action to enforce the standards set forth in
this subpart, you may assert an affirmative defense to a claim for civil
penalties for violations of such standards that are caused by
malfunction, as defined in 40 CFR 63.2. Appropriate penalties may be
assessed; however, if you fail to meet your burden of proving all of the
requirements in the affirmative defense, the affirmative defense shall
not be available for claims for injunctive relief.
[[Page 321]]
(1) To establish the affirmative defense in any action to enforce
such a standard, you must timely meet the reporting requirements in
paragraph (d)(2) of this section, and must prove by a preponderance of
evidence that:
(i) The violation:
(A) Was caused by a sudden, infrequent, and unavoidable failure of
air pollution control equipment, process equipment, or a process to
operate in a normal or usual manner; and
(B) Could not have been prevented through careful planning, proper
design or better operation and maintenance practices; and
(C) Did not stem from any activity or event that could have been
foreseen and avoided, or planned for; and
(D) Was not part of a recurring pattern indicative of inadequate
design, operation, or maintenance; and
(ii) Repairs were made as expeditiously as possible when a violation
occurred. Off-shift and overtime labor were used, to the extent
practicable to make these repairs; and
(iii) The frequency, amount and duration of the violation (including
any bypass) were minimized to the maximum extent practicable; and
(iv) If the violation resulted from a bypass of control equipment or
a process, then the bypass was unavoidable to prevent loss of life,
personal injury, or severe property damage; and
(v) All possible steps were taken to minimize the impact of the
violation on ambient air quality, the environment, and human health; and
(vi) All emissions monitoring and control systems were kept in
operation if at all possible, consistent with safety and good air
pollution control practices; and
(vii) All of the actions in response to the violation were
documented by properly signed, contemporaneous operating logs; and
(viii) At all times, the affected source was operated in a manner
consistent with good practices for minimizing emissions; and
(ix) A written root cause analysis has been prepared, the purpose of
which is to determine, correct, and eliminate the primary causes of the
malfunction and the violation resulting from the malfunction event at
issue. The analysis shall also specify, using best monitoring methods
and engineering judgment, the amount of any emissions that were the
result of the malfunction.
(2) Report. The owner or operator seeking to assert an affirmative
defense shall submit a written report to the Administrator with all
necessary supporting documentation, that it has met the requirements set
forth in paragraph (d)(1) of this section. This affirmative defense
report shall be included in the first periodic compliance, deviation
report or excess emission report otherwise required after the initial
occurrence of the violation of the relevant standard (which may be the
end of any applicable averaging period). If such compliance, deviation
report or excess emission report is due less than 45 days after the
initial occurrence of the violation, the affirmative defense report may
be included in the second compliance, deviation report or excess
emission report due after the initial occurrence of the violation of the
relevant standard.

instrument readings for the background organic concentration level, the
value of the arithmetic difference between the maximum organic
concentration value measured by the instrument and the background
organic concentration value as determined in paragraph (c)(5) of this
section is compared with the applicable value for the potential leak
interface as specified in paragraph (c)(8) of this section.

(ii) If the owner or operator and the Administrator do not agree on
a demonstration of control device performance using a design analysis
then the disagreement shall be resolved using the results of a
performance test performed by the owner or operator in accordance with
the requirements of paragraph (e)(3) of this section. The Administrator
may choose to have an authorized representative observe the performance
test.
(5) As an alternative to the procedures in paragraph (e)(4)(i) of
this section, an owner or operator may elect to use the procedures
documented in the
[[Page 337]]
GRI report entitled, ``Atmospheric Rich/Lean Method for Determining
Glycol Dehydrator Emissions'' (GRI-95/0368.1) as inputs for the model
GRI-GLYCalc \TM\, Version 3.0 or higher, to generate a condenser
performance curve.
(f) Compliance demonstration for control device performance
requirements. This paragraph applies to the demonstration of compliance
with the control device performance requirements specified in Sec.
63.771(d)(1)(i), (e)(3), and (f)(1). Compliance shall be demonstrated
using the requirements in paragraphs (f)(1) through (3) of this section.
As an alternative, an owner or operator that installs a condenser as the
control device to achieve the requirements specified in Sec.
63.771(d)(1)(ii), (e)(3), or (f)(1) may demonstrate compliance according
to paragraph (g) of this section. An owner or operator may switch
between compliance with paragraph (f) of this section and compliance
with paragraph (g) of this section only after at least 1 year of
operation in compliance with the selected approach. Notification of such
a change in the compliance method shall be reported in the next Periodic
Report, as required in Sec. 63.775(e), following the change.
(1) The owner or operator shall establish a site specific maximum or
minimum monitoring parameter value (as appropriate) according to the
requirements of Sec. 63.773(d)(5)(i).
(2) The owner or operator shall calculate the daily average of the
applicable monitored parameter in accordance with Sec. 63.773(d)(4)
except that the inlet gas flowrate to the control device shall not be
averaged.
(3) Compliance with the operating parameter limit is achieved when
the daily average of the monitoring parameter value calculated under
paragraph (f)(2) of this section is either equal to or greater than the
minimum or equal to or less than the maximum monitoring value
established under paragraph (f)(1) of this section. For inlet gas
flowrate, compliance with the operating parameter limit is achieved when
the value is equal to or less than the value established under Sec.
63.772(h) or under the performance test conducted under Sec. 63.772(e),
as applicable.
(4) Except for periods of monitoring system malfunctions, repairs
associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as
applicable, system accuracy audits and required zero and span
adjustments), the CMS required in Sec. 63.773(d) must be operated at
all times the affected source is operating. A monitoring system
malfunction is any sudden, infrequent, not reasonably preventable
failure of the monitoring system to provide valid data. Monitoring
system failures that are caused in part by poor maintenance or careless
operation are not malfunctions. Monitoring system repairs are required
to be completed in response to monitoring system malfunctions and to
return the monitoring system to operation as expeditiously as
practicable.
(5) Data recorded during monitoring system malfunctions, repairs
associated with monitoring system malfunctions, or required monitoring
system quality assurance or control activities may not be used in
calculations used to report emissions or operating levels. All the data
collected during all other required data collection periods must be used
in assessing the operation of the control device and associated control
system.
(6) Except for periods of monitoring system malfunctions, repairs
associated with monitoring system malfunctions, and required quality
monitoring system quality assurance or quality control activities
(including, as applicable, system accuracy audits and required zero and
span adjustments), failure to collect required data is a deviation of
the monitoring requirements.
(g) Compliance demonstration with percent reduction or emission
limit performance requirements--condensers. This paragraph applies to
the demonstration of compliance with the performance requirements
specified in Sec. 63.771(d)(1)(ii), (e)(3), or (f)(1) for condensers.
Compliance shall be demonstrated using the procedures in paragraphs
(g)(1) through (3) of this section.
(1) The owner or operator shall establish a site-specific condenser
performance curve according to Sec. 63.773(d)(5)(ii). For sources
required to meet the BTEX limit in accordance with Sec. 63.771(e) or
[[Page 338]]
(f)(1) the owner or operator shall identify the minimum percent
reduction necessary to meet the BTEX limit.
(2) Compliance with the requirements in Sec. 63.771(d)(1)(ii),
(e)(3), or (f)(1) shall be demonstrated by the procedures in paragraphs
(g)(2)(i) through (iii) of this section.
(i) The owner or operator must calculate the daily average condenser
outlet temperature in accordance with Sec. 63.773(d)(4).
(ii) The owner or operator shall determine the condenser efficiency
for the current operating day using the daily average condenser outlet
temperature calculated under paragraph (g)(2)(i) of this section and the
condenser performance curve established under paragraph (g)(1) of this
section.
(iii) Except as provided in paragraphs (g)(2)(iii)(A) and (B) of
this section, at the end of each operating day, the owner or operator
shall calculate the 365-day average HAP, or BTEX, emission reduction, as
appropriate, from the condenser efficiencies as determined in paragraph
(g)(2)(ii) of this section for the preceding 365 operating days. If the
owner or operator uses a combination of process modifications and a
condenser in accordance with the requirements of Sec. 63.771(e), the
365-day average HAP, or BTEX, emission reduction shall be calculated
using the emission reduction achieved through process modifications and
the condenser efficiency as determined in paragraph (g)(2)(ii) of this
section, both for the previous 365 operating days.
(A) After the compliance dates specified in Sec. 63.760(f), an
owner or operator with less than 120 days of data for determining
average HAP, or BTEX, emission reduction, as appropriate, shall
calculate the average HAP, or BTEX emission reduction, as appropriate,
for the first 120 days of operation after the compliance dates. For
sources required to meet the overall 95.0 percent reduction requirement,
compliance is achieved if the 120-day average HAP emission reduction is
equal to or greater than 90.0 percent. For sources required to meet the
BTEX limit under Sec. 63.765(b)(1)(iii), compliance is achieved if the
average BTEX emission reduction is at least 95.0 percent of the required
365-day value identified under paragraph (g)(1) of this section (i.e.,
at least 76.0 percent if the 365-day design value is 80.0 percent).
(B) After 120 days and no more than 364 days of operation after the
compliance dates specified in Sec. 63.760(f), the owner or operator
shall calculate the average HAP emission reduction as the HAP emission
reduction averaged over the number of days between the current day and
the applicable compliance date. For sources required to meet the overall
95.0-percent reduction requirement, compliance with the performance
requirements is achieved if the average HAP emission reduction is equal
to or greater than 90.0 percent. For sources required to meet the BTEX
limit under Sec. 63.765(b)(1)(iii), compliance is achieved if the
average BTEX emission reduction is at least 95.0 percent of the required
365-day value identified under paragraph (g)(1) of this section (i.e.,
at least 76.0 percent if the 365-day design value is 80.0 percent).
(3) If the owner or operator has data for 365 days or more of
operation, compliance is achieved based on the applicable criteria in
paragraphs (g)(3)(i) or (ii) of this section.
(i) For sources meeting the HAP emission reduction specified in
Sec. 63.771(d)(1)(ii) or (e)(3) the average HAP emission reduction
calculated in paragraph (g)(2)(iii) of this section is equal to or
greater than 95.0 percent.
(ii) For sources required to meet the BTEX limit under Sec.
63.771(e)(3) or (f)(1), compliance is achieved if the average BTEX
emission reduction calculated in paragraph (g)(2)(iii) of this section
is equal to or greater than the minimum percent reduction identified in
paragraph (g)(1) of this section.

the leak is detected.
(4) Delay of repair of a closed-vent system or cover for which leaks
or defects have been detected is allowed if the repair is technically
infeasible without a shutdown, as defined in Sec. 63.761, or if the
owner or operator determines that emissions resulting from immediate
repair would be greater than the fugitive emissions likely to result
from delay of repair. Repair of such equipment shall be complete by the
end of the next shutdown.
(5) Any parts of the closed-vent system or cover that are
designated, as described in paragraphs (c)(5) (i) and (ii) of this

Subpart II_National Emission Standards for Shipbuilding and Ship Repair
(Surface Coating)
Source: 60 FR 64336, Dec. 15, 1995, unless otherwise noted.
Sec. 63.780 Relationship of subpart II to subpart A of this part.
Table 1 of this subpart specifies the provisions of subpart A of
this part that apply to owners and operators of sources subject to the
provisions of this subpart.
Sec. 63.781 Applicability.
(a) The provisions of this subpart apply to shipbuilding and ship
repair operations at any facility that is a major source.
(b) The provisions of this subpart do not apply to coatings used in
volumes of less than 200 liters (52.8 gallons) per year, provided the
total volume of coating exempt under this paragraph does not exceed
1,000 liters per year (264 gallons per year) at any facility. Coatings
exempt under this paragraph shall be clearly labeled as ``low-usage
exempt,'' and the volume of each such coating applied shall be
maintained in the facility's records.
(c) The provisions of this subpart do not apply to coatings applied
with hand-held, nonrefillable, aerosol containers or to unsaturated
polyester resin (i.e., fiberglass lay-up) coatings. Coatings applied to
suitably prepared fiberglass surfaces for protective or decorative
purposes are subject to this subpart.
(d) If you are authorized in accordance with 40 CFR 63.783(c) to use
an add-on control system as an alternative means of limiting emissions
from coating operations, in response to an action to enforce the
standards set forth in this subpart, you may assert an affirmative
defense to a claim for civil penalties for exceedances of such standards
that are caused by a malfunction, as defined in 40 CFR 63.2. Appropriate
penalties may be assessed, however, if you fail to meet your burden of
proving all the requirements in the affirmative defense. The affirmative
defense shall not be available in response to claims for injunctive
relief.
(1) To establish the affirmative defense in any action to enforce
such a limit, you must timely meet the notification requirements in
paragraph (d)(2) of this section, and must prove by a preponderance of
evidence that:
(i) The excess emissions:
(A) Were caused by a sudden, infrequent and unavoidable failure of
air pollution control and monitoring equipment, process equipment or a
process to operate in a normal or usual manner; and
(B) Could not have been prevented through careful planning, proper
design or better operation and maintenance practices; and
(C) Did not stem from any activity or event that could have been
foreseen and avoided, or planned for; and
[[Page 361]]
(D) Were not part of a recurring pattern indicative of inadequate
design, operation, or maintenance; and
(ii) Repairs were made as expeditiously as possible when the
applicable emission limitations were being exceeded. Off-shift and
overtime labor were used, to the extent practicable to make these
repairs; and
(iii) The frequency, amount and duration of the excess emissions
(including any bypass) were minimized to the maximum extent practicable
during periods of such emissions; and
(iv) If the excess emissions resulted from a bypass of control
equipment or a process, then the bypass was unavoidable to prevent loss
of life, personal injury or severe property damage; and
(v) All possible steps were taken to minimize the impact of the
excess emissions on ambient air quality, the environment and human
health; and
(vi) All emissions monitoring and control systems were kept in
operation if at all possible, consistent with safety and good air
pollution control practices; and
(vii) All of the actions in response to the excess emissions were
documented by properly signed, contemporaneous operating logs; and
(viii) At all times, the affected source was operated in a manner
consistent with good practices for minimizing emissions; and
(ix) A written root cause analysis has been prepared, the purpose of
which is to determine, correct and eliminate the primary causes of the
malfunction and the excess emissions resulting from the malfunction
event at issue. The analysis shall also specify, using best monitoring
methods and engineering judgment, the amount of excess emissions that
were the result of the malfunction.
(2) Notification. The owner or operator of the facility experiencing
an exceedance of its emission limit(s) during a malfunction shall notify
the Administrator by telephone or facsimile (FAX) transmission as soon
as possible, but no later than 2 business days after the initial
occurrence of the malfunction, if it wishes to avail itself of an
affirmative defense to civil penalties for that malfunction. The owner
or operator seeking to assert an affirmative defense shall also submit a
written report to the Administrator within 45 days of the initial
occurrence of the exceedance of the standard in this subpart to
demonstrate, with all necessary supporting documentation, that it has
met the requirements set forth in paragraph (d)(1) of this section. The
owner or operator may seek an extension of this deadline for up to 30
additional days by submitting a written request to the Administrator
before the expiration of the 45 day period. Until a request for an
extension has been approved by the Administrator, the owner or operator
is subject to the requirement to submit such report within 45 days of
the initial occurrence of the exceedance.

Sec. 63.783 Standards.
(a) No owner or operator of any existing or new affected source
shall cause or allow the application of any coating to a ship with an
as-applied VOHAP content exceeding the applicable limit given in Table 2
of this subpart, as determined by the procedures described in Sec.
63.785 (c)(1) through (c)(4). For the compliance procedures described in
Sec. 63.785 (c)(1) through (c)(3), VOC shall be used as a surrogate for
VOHAP, and Method 24 of appendix A to 40 CFR part 60 shall be used as
the definitive measure for determining compliance. For the compliance
procedure described in Sec. 63.785(c)(4), an alternative test method
capable of measuring independent VOHAP shall be used to determine
compliance. The method must be submitted to and approved by the
Administrator.
(b) Each owner or operator of a new or existing affected source
shall ensure that:
(1) At all times the owner or operator must operate and maintain any
affected source, including associated air pollution control equipment
and monitoring equipment, in a manner consistent with safety and good
air pollution control practices for minimizing emissions. Determination
of whether
[[Page 365]]
such operation and maintenance procedures are being used will be based
on information available to the Administrator which may include, but is
not limited to, monitoring results, review of operation and maintenance
procedures, review of operation and maintenance records, and inspection
of the source.
(2) All handling and transfer of VOHAP-containing materials to and
from containers, tanks, vats, drums, and piping systems is conducted in
a manner that minimizes spills.
(3) All containers, tanks, vats, drums, and piping systems are free
of cracks, holes, and other defects and remain closed unless materials
are being added to or removed from them.
(c) Approval of alternative means of limiting emissions. (1) The
owner or operator of an affected source may apply to the Administrator
for permission to use an alternative means (such as an add-on control
system) of limiting emissions from coating operations. The application
must include:
(i) An engineering material balance evaluation that provides a
comparison of the emissions that would be achieved using the alternative
means to those that would result from using coatings that comply with
the limits in Table 2 of this subpart, or the results from an emission
test that accurately measures the capture efficiency and control device
efficiency achieved by the control system and the composition of the
associated coatings so that the emissions comparison can be made;
(ii) A proposed monitoring protocol that includes operating
parameter values to be monitored for compliance and an explanation of
how the operating parameter values will be established through a
performance test; and
(iii) Details of appropriate recordkeeping and reporting procedures.
(2) The Administrator shall approve the alternative means of
limiting emissions if, in the Administrator's judgment, postcontrol
emissions of VOHAP per volume applied solids will be no greater than
those from the use of coatings that comply with the limits in Table 2 of
this subpart.
(3) The Administrator may condition approval on operation,
maintenance, and monitoring requirements to ensure that emissions from
the source are no greater than those that would otherwise result from
this subpart.

Sec. 63.784 Compliance dates.
(a) Each owner or operator of an existing affected source shall
comply within two years after the effective date of this subpart.
(b) Each owner or operator of an existing unaffected area source
that increases its emissions of (or its potential to emit) HAP such that
the source becomes a major source that is subject to this subpart shall
comply within 1 year after the date of becoming a major source.
(c) Each owner or operator of a new or reconstructed source shall
comply with this subpart according to the schedule in Sec. 63.6(b).
[60 FR 64336, Dec. 15, 1995, as amended at 61 FR 30816, June 18, 1996]
Sec. 63.785 Compliance procedures.
(a) For each batch of coating that is received by an affected
source, the owner or operator shall (see Figure 1 of this section for a
flow diagram of the compliance procedures):
(1) Determine the coating category and the applicable VOHAP limit as
specified in Sec. 63.783(a).
(2) Certify the as-supplied VOC content of the batch of coating. The
owner or operator may use a certification supplied by the manufacturer
for the batch, although the owner or operator retains liability should
subsequent testing reveal a violation. If the owner or operator performs
the certification testing, only one of the containers in which the batch
of coating was received is required to be tested.
(b)(1) In lieu of testing each batch of coating, as applied, the
owner or operator may determine compliance with the VOHAP limits using
any combination of the procedures described in paragraphs (c)(1),
(c)(2), (c)(3), and (c)(4) of this section. The procedure used for each
coating shall be determined and documented prior to application.
(2) The results of any compliance demonstration conducted by the
affected source or any regulatory agency
[[Page 366]]
using Method 24 shall take precedence over the results using the
procedures in paragraphs (c)(1), (c)(2), or (c)(3) of this section.
(3) The results of any compliance demonstration conducted by the
affected source or any regulatory agency using an approved test method
to determine VOHAP content shall take precedence over the results using
the procedures in paragraph (c)(4) of this section.
(c)(1) Coatings to which thinning solvent will not be added. For
coatings to which thinning solvent (or any other material) will not be
added under any circumstance or to which only water is added, the owner
or operator of an affected source shall comply as follows:
(i) Certify the as-applied VOC content of each batch of coating.
(ii) Notify the persons responsible for applying the coating that no
thinning solvent may be added to the coating by affixing a label to each
container of coating in the batch or through another means described in
the implementation plan required in Sec. 63.787(b).
(iii) If the certified as-applied VOC content of each batch of
coating used during a calendar month is less than or equal to the
applicable VOHAP limit in Sec. 63.783(a) (either in terms of g/L of
coating or g/L of solids), then compliance is demonstrated for that
calendar month, unless a violation is revealed using Method 24 of
appendix A to 40 CFR part 60.
(2) Coatings to which thinning solvent will be added--coating-by-
coating compliance. For a coating to which thinning solvent is routinely
or sometimes added, the owner or operator shall comply as follows:
(i) Prior to the first application of each batch, designate a single
thinner for the coating and calculate the maximum allowable thinning
ratio (or ratios, if the affected source complies with the cold-weather
limits in addition to the other limits specified in Table 2 of this
subpart) for each batch as follows:
[GRAPHIC] [TIFF OMITTED] TR15DE95.191
where:
R = Maximum allowable thinning ratio for a given batch (L thinner/L
coating as supplied);
Vs = Volume fraction of solids in the batch as supplied (L
solids/L coating as supplied);
VOHAP limit = Maximum allowable as-applied VOHAP content of the coating
(g VOHAP/L solids);
mVOC = VOC content of the batch as supplied [g VOC (including
cure volatiles and exempt compounds on the HAP list)/L coating
(including water and exempt compounds) as supplied];
Dth = Density of the thinner (g/L).
If Vs is not supplied directly by the coating
manufacturer, the owner or operator shall determine Vs as
follows:
[GRAPHIC] [TIFF OMITTED] TR15DE95.192
where:
mvolatiles = Total volatiles in the batch, including VOC,
water, and exempt compounds (g/L coating); and
Davg = Average density of volatiles in the batch (g/L).
The procedures specified in Sec. 63.786(d) may be used to determine
the values of variables defined in this paragraph. In addition, the
owner or operator may choose to construct nomographs, based on Equation
1 of this subpart, similar or identical to the one provided in appendix
B of this subpart as a means of easily estimating the maximum allowable
thinning ratio.
(ii) Prior to the first application of each batch, notify painters
and other persons, as necessary, of the designated thinner and maximum
allowable thinning ratio(s) for each batch of the coating by affixing a
label to each container of coating or through another means described in
the implementation plan required in Sec. 63.787(b).
(iii) By the 15th day of each calendar month, determine the volume
of each batch of the coating used, as supplied, during the previous
month.
(iv) By the 15th day of each calendar month, determine the total
allowable volume of thinner for the coating used during the previous
month as follows:
[[Page 367]]
[GRAPHIC] [TIFF OMITTED] TR15DE95.193
where:
Vth = Total allowable volume of thinner for the previous
month (L thinner);
Vb = Volume of each batch, as supplied and before being
thinned, used during non-cold-weather days of the previous
month (L coating as supplied);
Rcold = Maximum allowable thinning ratio for each batch used
during cold-weather days (L thinner/L coating as supplied);
Vb-cold = Volume of each batch, as supplied and before being
thinned, used during cold-weather days of the previous month
(L coating as supplied);
i = Each batch of coating; and
n = Total number of batches of the coating.
(v) By the 15th day of each calendar month, determine the volume of
thinner actually used with the coating during the previous month.
(vi) If the volume of thinner actually used with the coating
[paragraph (c)(3)(v) of this section] is less than or equal to the total
allowable volume of thinner for the coating [paragraph (c)(3)(iv) of
this section], then compliance is demonstrated for the coating for the
previous month, unless a violation is revealed using Method 24 of
appendix A to 40 CFR part 60.
(3) Coatings to which the same thinning solvent will be added--group
compliance. For coatings to which the same thinning solvent (or other
material) is routinely or sometimes added, the owner or operator shall
comply as follows:
(i) Designate a single thinner to be added to each coating during
the month and ``group'' coatings according to their designated thinner.
(ii) Prior to the first application of each batch, calculate the
maximum allowable thinning ratio (or ratios, if the affected source
complies with the cold-weather limits in addition to the other limits
specified in Table 2 of this subpart) for each batch of coating in the
group using the equations in paragraph (c)(2) of this section.
(iii) Prior to the first application of each ``batch,'' notify
painters and other persons, as necessary, of the designated thinner and
maximum allowable thinning ratio(s) for each batch in the group by
affixing a label to each container of coating or through another means
described in the implementation plan required in Sec. 63.787(b).
(iv) By the 15th day of each calendar month, determine the volume of
each batch of the group used, as supplied, during the previous month.
(v) By the 15th day of each calendar month, determine the total
allowable volume of thinner for the group for the previous month using
Equation 3 of this subpart.
(vi) By the 15th day of each calendar month, determine the volume of
thinner actually used with the group during the previous month.
(vii) If the volume of thinner actually used with the group
[paragraph (c)(3)(vi) of this section] is less than or equal to the
total allowable volume of thinner for the group [paragraph (c)(3)(v) of
this section], then compliance is demonstrated for the group for the
previous month, unless a violation is revealed using Method 24 of
appendix A to 40 CFR part 60.
(4) Demonstration of compliance through an alternative (i.e., other
than Method 24 of appendix A to 40 CFR part 60) test method. The owner
or operator shall comply as follows:
(i) Certify the as-supplied VOHAP content (g VOHAP/L solids) of each
batch of coating.
(ii) If no thinning solvent will be added to the coating, the owner
or operator of an affected source shall follow the procedure described
in Sec. 63.785(c)(1), except that VOHAP content shall be used in lieu
of VOC content.
(iii) If thinning solvent will be added to the coating, the owner or
operator of an affected source shall follow the procedure described in
Sec. 63.785(c)(2) or (3), except that in Equation 1 of this subpart:
the term ``mVOC'' shall be replaced by the term
``mVOHAP,'' defined as the VOHAP content of the coating as
supplied (g VOHAP/L coating) and the term ``Dth'' shall be
replaced by the
[[Page 368]]
term ``Dth(VOHAP)'' defined as the average density of the
VOHAP thinner(s) (g/L).
(d) A violation revealed through any approved test method shall
result in a 1-day violation for enforcement purposes. A violation
revealed through the recordkeeping procedures described in paragraphs
(c)(1) through (c)(4) of this section shall result in a 30-day violation
for enforcement purposes, unless the owner or operator provides
sufficient data to demonstrate the specific days during which
noncompliant coatings were applied.
(e) Continuous compliance requirements. You must demonstrate
continuous compliance with the emissions standards and operating limits
by using the performance test methods and procedures in Sec. 63.786 for
each affected source.
(1) General requirements. (i) You must monitor and collect data, and
provide a site specific monitoring plan, as required by Sec. Sec.
63.783, 63.785, 63.786 and 63.787.
(ii) Except for periods of monitoring system malfunctions, repairs
associated with monitoring system malfunctions, and required monitoring
system quality assurance or quality control activities (including, as
applicable, calibration checks and required zero and span adjustments),
you must operate the monitoring system and collect data at all required
intervals at all times the affected source is operating, and periods of
malfunction. Any period for which data collection is required and the
operation of the Continuous Emissions Monitoring System (CEMS) is not
otherwise exempt and for which the monitoring system is out-of-control
and data are not available for required calculations constitutes a
deviation from the monitoring requirements.
(iii) You may not use data recorded during monitoring system
malfunctions, repairs associated with monitoring system malfunctions or
required monitoring system quality assurance or control activities in
calculations used to report emissions or operating levels. A monitoring
system malfunction is any sudden, infrequent, not reasonably preventable
failure of the monitoring system to provide valid data. Monitoring
system failures that are caused in part by poor maintenance or careless
operation are not malfunctions. The owner or operator must use all the
data collected during all other periods in assessing the operation of
the control device and associated control system.

[60 FR 64336, Dec. 15, 1995, as amended at 76 FR 72069, Nov. 21, 2011]
Sec. 63.786 Test methods and procedures.
(a) For the compliance procedures described in Sec. 63.785(c) (1)
through (c)(3),
[[Page 370]]
Method 24 of 40 CFR part 60, appendix A, is the definitive method for
determining the VOC content of coatings, as supplied or as applied. When
a coating or thinner contains exempt compounds that are volatile HAP or
VOHAP, the owner or operator shall ensure, when determining the VOC
content of a coating, that the mass of these exempt compounds is
included.
(b) For the compliance procedure described in Sec. 63.785(c)(4),
the Administrator must approve the test method for determining the VOHAP
content of coatings and thinners. As part of the approval, the test
method must meet the specified accuracy limits indicated below for
sensitivity, duplicates, repeatability, and reproducibility coefficient
of variation each determined at the 95 percent confidence limit. Each
percentage value below is the corresponding coefficient of variation
multiplied by 2.8 as in the ASTM Method E180-93: Standard Practice for
Determining the Precision of ASTM Methods for Analysis and Testing of
Industrial Chemicals (incorporation by reference--see Sec. 63.14).
(1) Sensitivity. The overall sensitivity must be sufficient to
identify and calculate at least one mass percent of the compounds of
interest based on the original sample. The sensitivity is defined as ten
times the noise level as specified in ASTM Method D3257-93: Standard
Test Methods for Aromatics in Mineral Spirits by Gas Chromatography
(incorporation by reference--see Sec. 63.14). In determining the
sensitivity, the level of sample dilution must be factored in.
(2) Repeatability. First, at the 0.1-5 percent analyte range the
results would be suspect if duplicates vary by more than 6 percent
relative and/or day to day variation of mean duplicates by the same
analyst exceeds 10 percent relative. Second, at greater than 5 percent
analyte range the results would be suspect if duplicates vary by more
than 5 percent relative and/or day to day variation of duplicates by the
same analyst exceeds 5 percent relative.
(3) Reproducibility. First, at the 0.1-5 percent analyte range the
results would be suspect if lab to lab variation exceeds 60 percent
relative. Second, at greater than 5 percent range the results would be
suspect if lab to lab variation exceeds 20 percent relative.
(4) Any test method should include information on the apparatus,
reagents and materials, analytical procedure, procedure for
identification and confirmation of the volatile species in the mixture
being analyzed, precision and bias, and other details to be reported.
The reporting should also include information on quality assurance (QA)
auditing.
(5) Multiple and different analytical techniques must be used for
positive identification if the components in a mixture under analysis
are not known. In such cases a single column gas chromatograph (GC) may
not be adequate. A combination of equipment may be needed such as a GC/
mass spectrometer or GC/infrared system. (If a GC method is used, the
operator must use practices in ASTM Method E260-91 or 96: Standard
Practice for Gas Chromatography [incorporation by reference--see Sec.
63.14].)
(c) A coating manufacturer or the owner or operator of an affected
source may use batch formulation data as a test method in lieu of Method
24 of appendix A to 40 CFR part 60 to certify the as-supplied VOC
content of a coating if the manufacturer or the owner or operator has
determined that batch formulation data have a consistent and
quantitatively known relationship to Method 24 results. This
determination shall consider the role of cure volatiles, which may cause
emissions to exceed an amount based solely upon coating formulation
data. Notwithstanding such determination, in the event of conflicting
results, Method 24 of appendix A of 40 CFR part 60 shall take
precedence.
(d) Each owner or operator of an affected source shall use or ensure
that the manufacturer uses the form and procedures mentioned in appendix
A of this subpart to determine values for the thinner and coating
parameters used in Equations 1 and 2 of this subpart. The owner or
operator shall ensure that the coating/thinner manufacturer (or
supplier) provides information on the VOC and VOHAP contents of the
coatings/thinners and the procedure(s) used to determine these values.
[[Page 371]]
(e) For add-on control systems approved for use in limiting
emissions from coating operations pursuant to Sec. 63.783(c),
performance tests shall be conducted under such conditions as the
Administrator specifies to the owner or operator based on representative
performance of the affected source for the period being tested. Upon
request, the owner or operator shall make available to the Administrator
such records as may be necessary to demonstrate the conditions present
during performance tests.

applicable.
(2) [Reserved]
(3) Implementation plan contents. Each implementation plan shall
address the following subject areas:
(i) Coating compliance procedures. The implementation plan shall
include the compliance procedure(s) under Sec. 63.785(c) that the
source intends to use.
(ii) Recordkeeping procedures. The implementation plan shall include
the procedures for maintaining the records required under Sec. 63.788,
including the procedures for gathering the necessary data and making the
necessary calculations.
(iii) Transfer, handling, and storage procedures. The implementation
plan shall include the procedures for ensuring compliance with Sec.
63.783(b).
(4) Major sources that intend to become area sources by the
compliance date. Existing major sources that intend to become area
sources by the December 16, 1997 compliance date may choose to submit,
in lieu of the implementation plan required under paragraph (b)(1) of
this section, a statement that, by the compliance date, the major source
intends to obtain and comply with federally enforceable limits on their

\a\ The limits are expressed in two sets of equivalent units. Either set
of limits may be used for the compliance procedure described in Sec.
63.785(c)(1), but only the limits expressed in units of g/L solids
(nonvolatiles) shall be used for the compliance procedures described
Sec. 63.785(c) (2) through (4).
\b\ VOC (including exempt compounds listed as HAP) shall be used as a
surrogate for VOHAP for those compliance procedures described in Sec.
63.785(c) (1) through (3).
\c\ To convert from g/L to lb/gal, multiply by (3.785 L/gal)(1/453.6 lb/
g) or 1/120. For compliance purposes, metric units define the
standards.
\d\ VOHAP limits expressed in units of mass of VOHAP per volume of
solids were derived from the VOHAP limits expressed in units of mass
of VOHAP per volume of coating assuming the coatings contain no water
or exempt compounds and that the volumes of all components within a
coating are additive.
\e\ These limits apply during cold-weather time periods, as defined in
Sec. 63.782. Cold-weather allowances are not given to coatings in
categories that permit less than 40 percent volume solids
(nonvolatiles). Such coatings are subject to the same limits
regardless of weather conditions.

\a\ Affected sources that comply with the cold-weather limits must record and report additional information, as
specified in Sec. 63.788(b)(3) (ii)(C), (iii)(C), and (iv)(D).
\b\ Affected sources that detect a violation must record and report additional information, as specified in Sec.
63.788(b)(4).
\c\ OPTION 4: the recordkeeping and reporting requirements of Option 4 are identical to those of Options 1, 2,
or 3, depending on whether and how thinners are used. However, when using Option 4, the term ``VOHAP'' shall
be used in lieu of the term ``VOC,'' and the owner or operator shall record and report the Administrator-
approved VOHAP test method or certification procedure.
\d\ Major sources that intend to become area sources by the compliance date may, in lieu of submitting an
implementation plan, choose to submit a statement of intent as specified in Sec. 63.787(b)(4).
