Subpart L--Fluorinated Gas Production

Sec.  98.120  Definition of the source category.

    (a) The fluorinated gas production source category consists of
processes that produce a fluorinated gas from any raw material or
feedstock chemical, except for processes that generate HFC-23 during
the production of HCFC-22.
    (b) To produce a fluorinated gas means to manufacture a fluorinated
gas from any raw material or feedstock chemical. Producing a
fluorinated gas includes producing a fluorinated GHG as defined at
Sec.  98.410(b). Producing a fluorinated gas also includes the
manufacture of a chlorofluorocarbon (CFC) or hydrochlorofluorocarbon
(HCFC) from any raw material or feedstock chemical, including
manufacture for use in a process that will result in the transformation
of the CFC or HCFC either at or outside of the production facility.
Producing a fluorinated gas does not include the reuse or recycling of
a fluorinated gas, the creation of HFC-23 during the production of
HCFC-22, or the creation of by-products that are released or destroyed
at the production facility.

Sec.  98.121  Reporting threshold.

    You must report GHG emissions under this subpart if your facility
contains a fluorinated gas production process that generates or emits
fluorinated GHG and the facility meets the requirements of either Sec.
98.2(a)(1) or (a)(2) of this part. To calculate GHG emissions for
comparison to the 25,000 metric ton CO2e per year emission
threshold in Sec.  98.2(a)(2), calculate process emissions from
fluorinated gas production using uncontrolled GHG emissions.

Sec.  98.122  GHGs to report.

    (a) You must report CO2, CH4, and
N2O combustion emissions from each stationary combustion
unit. You must calculate and report these emissions under subpart C of
this part (General Stationary Fuel Combustion Sources) by following the
requirements of subpart C.

    (b) You must report under subpart O of this part (HCFC-22
Production and HFC-23 Destruction) the emissions of HFC-23 from HCFC-22
production processes and HFC-23 destruction processes. Do not report
the generation and emissions of HFC-23 from HCFC-22 production under
this subpart.
    (c) You must report the total mass of each fluorinated GHG from:
    (1) Each fluorinated gas production process and all fluorinated gas
production processes combined.
    (2) Each fluorinated gas transformation process that is not part of
a fluorinated gas production process and all such fluorinated gas
transformation processes combined.
    (3) Each fluorinated gas destruction process that is not part of a
fluorinated gas production process or a fluorinated gas transformation
process and all such fluorinated gas destruction processes combined.

Sec.  98.123  Calculating GHG emissions.

    For fluorinated GHG production processes, you must calculate the
fluorinated GHG emissions from each process using either the mass
balance method specified in paragraph (a) of this section or the
emission factor or emission calculation factor method specified in
paragraphs (b), (c), and (d) of this section, as appropriate. For
processes that manufacture CFCs or HCFCs or that transform fluorinated
gases into substances other than fluorinated GHGs, you must use the
procedures in paragraphs (b), (c), and (d) of this section. For
destruction processes that destroy fluorinated GHGs that were
previously ``produced'' as defined at 98.410(b), you must use the
procedures in paragraph (e) of this section.
    (a) Mass balance method. Before using the mass balance approach to
estimate your fluorinated GHG emissions from a process, you must
estimate the absolute and relative errors associated with using the
mass balance approach on that process using Equations L-1 through L-4
of this section in conjunction with Equations L-7 through L-12 of this
section. If this calculation shows that use of the mass-balance
approach to estimate emissions from the process will result in an
absolute error exceeding 3,000 metric tons CO2e per year and
a relative error exceeding 30 percent, then you cannot use the mass-
balance approach to estimate emissions from the process. Instead, you
must use the emission factor approach detailed in paragraphs (b), (c),
and (d) of this section to estimate emissions from the process. To
perform the calculation, you shall first calculate the absolute and
relative errors associated with the quantities calculated using
Equations L-8 through L-11. Once errors have been calculated for the
quantities in these equations, those errors shall be used to calculate
the errors in Equations L-7 and L-12. Where the measured quantity is a
mass, the error in the mass shall be equated to the accuracy or
precision (whichever is larger) of the flowmeter, scale, or combination
of volumetric and density measurements at the flow rate or mass
measured. Where the measured quantity is a concentration, the error of
the concentration shall be equated to the accuracy or precision
(whichever is larger) of the analytical technique used to measure the
concentration at the concentration measured.
    (1) Equation L-1 of this section provides the general formula for
calculating the absolute errors of sums and differences where the sum,
S, is the summation of variables measured, a, b, c, etc. (e.g., S = a +
b + c):
[GRAPHIC] [TIFF OMITTED] TP12AP10.051

Where:
    eSA = absolute error of the sum, expressed as one
half of a 95 percent confidence interval.
    ea = relative error of a, expressed as one half of a
95 percent confidence interval.
    eb = relative error of b, expressed as one half of a
95 percent confidence interval.
    ec = relative error of c, expressed as one half of a
95 percent confidence interval.

    (2) Equation L-2 of this section provides the general formula for

Where:

half of a 95 percent confidence interval.
    eSA = absolute error of the sum, expressed as one
half of a 95 percent confidence interval.
    a+b+c = sum of the variables measured.

    (3) Equation L-3 provides the general formula for calculating the
absolute errors of products (e.g., flow rates of GHGs calculated as the
product of the flow rate of the stream and the concentration of the GHG
in the stream), where the product, P, is the result of multiplying the
variables measured, a, b, c, etc. (e.g., P = a*b*c):
[GRAPHIC] [TIFF OMITTED] TP12AP10.053

Where:
    ePA = absolute error of the product, expressed as one
half of a 95 percent confidence interval.
    ea = relative error of a, expressed as one half of a
95 percent confidence interval.
    eb = relative error of b, expressed as one half of a
95 percent confidence interval.
    ec = relative error of c, expressed as one half of a
95 percent confidence interval.

    (4) Equation L-4 of this section provides the general formula for
calculating the relative errors of products:
[GRAPHIC] [TIFF OMITTED] TP12AP10.054

Where:
    ePR = relative error of the product, expressed as one
half of a 95 percent confidence interval.
    ePA = absolute error of the product, expressed as one
half of a 95 percent confidence interval.
    a*b*c = product of the variables measured.

    (5) The total mass of each fluorinated GHG product emitted annually

monthly by calculating the difference between the expected production
of the fluorinated GHG based on the consumption of one of the reactants
(e.g., HF or a chlorocarbon reactant) and the measured production of

and wastes. This calculation shall be performed using Equation L-7 of

    (b) Emission factor and emission calculation factor methods. To use
the method in this paragraph, you must first make a preliminary
estimate of the emissions from each individual process vent under
paragraph (b)(1) of this section. Then, compare the preliminary
estimate to the criteria in paragraph (b)(2) of this section to
determine whether the process vent meets the criteria for using the
emission factor method described in paragraph (b)(3) of this section or
whether the process vent meets the criteria for using the emission
calculation factor method described in paragraph (b)(4) of this
section.
    (1) Preliminary estimate of emissions by process vent. You must
estimate the annual uncontrolled emissions of fluorinated GHG for each
process vent within a process. You may determine uncontrolled emissions
of fluorinated GHG by process vent using existing measurements and/or
calculations based on chemical engineering principles and chemical
property data or you may conduct an engineering assessment. You must
document all data, assumptions, and procedures used in the calculations
or engineering assessment and keep a record of the uncontrolled
emissions determination (in Sec.  98.127(a)).
    (i) Engineering calculations. For process vent emission
calculations, you may use paragraph (b)(1)(i)(A), (B), or (C) of this
section.
    (A) Emissions Inventory Improvement Process, Volume II: Chapter 16,
Methods for Estimating Air Emissions from Chemical Manufacturing
Facilities. U.S. Environmental Protection Agency, August 2007.
    (B) You may determine the uncontrolled fluorinated GHG emissions
from any process vent within the process using the procedures specified
in 40 CFR Sec.  63.1257(d)(2)(i), except as specified in paragraphs
(b)(1)(i)(B)(1) through (b)(1)(i)(B)(7) of this section. For the
purposes of this subpart, use of the term ``HAP'' in Sec.
63.1257(d)(2)(i) shall mean ``fluorinated GHG''.
    (1) To calculate emissions caused by the heating of a vessel
without a process condenser to a temperature lower than the boiling
point, you must use the procedures in Sec.  63.1257(d)(2)(i)(C)(3).
    (2) To calculate emissions from depressurization of a vessel
without a process condenser, you must use the procedures in Sec.
63.1257(d)(2)(i)(D)(10).
    (3) To calculate emissions from vacuum systems, the terms used in
Equation 33 to 40 CFR part 63, subpart GGG, are defined as follows:
    (i) Psystem = absolute pressure of the receiving vessel;
    (ii) Pi = partial pressure of the fluorinated GHG
determined at the exit temperature and exit pressure conditions of the
condenser or at the conditions of the dedicated receiver;
    (iii) Pj = partial pressure of condensables (including
fluorinated GHG) determined at the exit temperature and exit pressure
conditions of the condenser or at the conditions of the dedicated
receiver;
    (iv) MWFluorinated GHG = molecular weight of the
fluorinated GHG determined at the exit temperature and exit pressure
conditions of the condenser or at the conditions of the dedicated
receiver.
    (4) To calculate uncontrolled emissions when a vessel is equipped
with a process condenser, you must use the procedures in 40 CFR
63.1257(d)(3)(i)(B), except as follows:
    (i) You must determine the flowrate of gas (or volume of gas),
partial pressures of condensables, temperature (T), and fluorinated GHG
molecular weight (MWFluorinated GHG) at the exit temperature
and exit pressure conditions of the condenser or at the conditions of
the dedicated receiver.
    (ii) You must assume that all of the components contained in the
condenser exit vent stream are in equilibrium with the same components
in the exit condensate stream (except for noncondensables).
    (iii) You must perform a material balance for each component.
    (iv) For the emissions from gas evolution, the term for time, t,
must be used in Equation 12 to 40 CFR part 63, subpart GGG.
    (v) Emissions from empty vessel purging shall be calculated using
Equation 36 to 40 CFR part 63, subpart GGG and the exit temperature and
exit pressure conditions of the condenser or the conditions of the
dedicated receiver.
    (C) Commercial software products that follow chemical engineering
principles, including the calculation methodologies in paragraphs
(b)(1)(i)(A) and (B) of this section.
    (ii) Engineering assessments. For process vent emissions
determinations, you may conduct an engineering assessment to calculate
uncontrolled emissions for each emission episode. An engineering
assessment includes, but is not limited to, the following:
    (A) Previous test results, provided the tests are representative of
current operating practices of the process.
    (B) Bench-scale or pilot-scale test data representative of the
process under representative operating conditions.
    (C) Maximum flow rate, fluorinated GHG emission rate,
concentration, or other relevant parameters specified or implied within
a permit limit applicable to the process vent.
    (D) Design analysis based on chemical engineering principles,
measureable process parameters, or physical or chemical laws or
properties.

    (2) Process vent annual mass limit and control determination.
    (i) If the individual process vent meets the criteria in either
paragraph (b)(2)(i)(A) or (b)(2)(i)(B) of this section, then you may
comply with either paragraph (b)(3) (Emission Factor approach) or
paragraph (b)(4) (Emission Calculation Factor approach).
    (A) Uncontrolled fluorinated GHG emissions for the individual
process vent as estimated using procedures in paragraph (b)(1) of this
section are less than 10,000 metric tons CO2e per year or,
for emissions including fluorinated GHGs whose GWPs are not listed in
Table A-1, 1 metric ton per year.
    (B) The individual process vent is vented to a destruction device
demonstrated to achieve a destruction efficiency of 99.9 percent for
the fluorinated GHGs in the vent stream, and the facility has equipment
(e.g., holding tank capacity; monitoring of by-pass streams) or
procedures (e.g., compulsory process shutdowns) in place that ensure
that uncontrolled emissions do not occur. For each process, you should
either track the amount of production or other process activity that is
vented to the destruction device or track production or other process
activity that by-passes the destruction device.
    (ii) If the individual process vent does not meet the criteria in
either paragraph (b)(2)(i)(A) or (b)(2)(i)(B) of this section, then the
facility must comply with the emission factor method specified in
paragraph (b)(3) of this section.
    (3) Process-vent-specific emission factor method. For each process
vent, conduct an emission test and measure uncontrolled fluorinated GHG
emissions from the process and measure the process activity, such as
the feed rate, production rate, or other process activity rate, during
the test as described in this paragraph (b)(3). All emissions test data
and procedures used in developing emission factors shall be documented

runs conducted for the test.

    (c) Calculate fluorinated GHG emissions for equipment leaks (EL).
If you comply with paragraph (b) of this section, you must calculate
the fluorinated GHG emissions from pieces of equipment associated with
processes covered under this subpart and in fluorinated GHG service.
The emissions from equipment leaks must be calculated using one of the
following methods in the Protocol for Equipment Leak Emission
Estimates, U.S. Environmental Protection Agency, EPA Publication No.
EPA-453/R-95-017, November 1995: the Screening Ranges Approach; the EPA
Correlation Approach; or the Unit-Specific Correlation Approach. You
may not use the procedure in the protocol for Average Emission Factor
Approach.
    (1) You must develop response factors for each fluorinated GHG or
for each surrogate to be measured using EPA Method 21, 40 CFR part 60,
Appendix A-7. For each fluorinated GHG measured, the response factor
shall be less than 10. The response factor is the ratio of the known
concentration of a fluorinated GHG to the observed meter reading when
measured using an instrument calibrated with the reference compound.
    (2) You must collect information on the number of each type of
equipment; the service of each piece of equipment (gas, light liquid,
heavy liquid); the concentration of each fluorinated GHG in the stream;
and the time period each piece of equipment was in service. Depending
on which approach you follow, you must collect information for
equipment on the associated screening data concentrations for greater
than or equal to 10,000 ppmv and associated screening data
concentrations for less than 10,000 ppmv; associated actual screening
data concentrations; and associated screening data and leak rate data

Sec.  98.124  Monitoring and QA/QC requirements.

    (a) Initial scoping test for fluorinated GHGs. You must conduct an
initial scoping test to identify all fluorinated GHGs that may be
generated from processes that are subject to this subpart and that have
uncontrolled emissions (i.e., pre-control emissions levels) of 1.0
metric ton or more of fluorinated GHGs. For each process, you must
conduct the initial scoping test on the stream(s) (including process
streams or destroyed streams) or process vent(s) that would be expected
to individually or collectively contain all of the fluorinated GHG by-
products of the process. Initial scoping testing must be conducted
according to the procedures in paragraph (c)(4)(v) of this section.
    (b) Mass Balance monitoring. If you determine fluorinated GHG
emissions using the mass balance method under Sec.  98.123(a), you must
estimate the total mass of each fluorinated GHG emitted from the
process at least monthly.
    (1) You must conduct the following mass measurements on a monthly
or more frequent basis using flowmeters, weigh scales, or a combination
of volumetric and density measurements with accuracy and precision that
allow the facility to meet the error criteria in Sec.  98.123(a):
    (i) Total mass of each fluorinated GHG produced shall be estimated
using the methods and measurements set forth in Sec.  98.413(a) and (b)
and in Sec.  98.414(a) and (b). For each fluorinated GHG, the mass
produced used for the mass-balance calculation shall be the same as the
mass produced that is reported under subpart OO.
    (ii) Total mass of each reactant fed into the production process
shall be measured.
    (iii) Total mass of each reactant permanently removed from the
production process shall be measured.
    (iv) If the waste permanently removed from the production process
and fed into the destruction device contains more than trace
concentrations of fluorinated GHG product, then the mass of waste fed
into the destruction device shall be measured.
    (v) If a by-product is responsible for yield loss and occurs in any
stream (including process steams, emissions streams, or destroyed
streams) in more than trace concentrations, then the mass flow of each
stream that contains more than trace concentrations of the by-product
shall be measured.
    (vi) If a by-product is a fluorinated GHG (other than HFC-23
generated during HCFC-22 production), occurs in more than trace
concentrations in any stream (including process streams, emissions
streams, or destroyed streams), occurs in more than trace
concentrations in any stream that is recaptured or is fed into a
destruction device, and is not completely recaptured or completely
destroyed, then the mass flow of each stream that contains more than
trace concentrations of the by-product and that is recaptured or is fed
into the destruction device shall be measured.
    (2) The following concentration measurements shall be measured on a
regular basis using equipment and methods (e.g., gas chromatography)
with an accuracy and precision that allow the facility to meet the
error criteria in Sec.  98.123(a):
    (i) If the waste permanently removed from the production process
and fed into the destruction device contains more than trace
concentrations of fluorinated GHG product and if the stream mass
includes more than trace concentrations of materials other than the
product, then the concentration of the product shall be measured.
    (ii) If a by-product is responsible for yield loss and occurs in
any stream (including process streams, emissions streams, or destroyed
streams) in more than trace concentrations and if the stream mass
includes more than trace concentrations of materials other than the by-
product, then the concentration of the by-product shall be measured.
    (iii) If a by-product is a fluorinated GHG, occurs in more than
trace concentrations in any stream (including process streams,
emissions streams, or destroyed streams), occurs in more than trace
concentrations in any stream that is recaptured or is fed into a
destruction device, and is not completely recaptured or completely
destroyed, and if the measured stream mass includes more than trace
concentrations of materials other than the by-product, then the
concentration of the by-product shall be measured.
    (c) Emission factor testing. If you determine fluorinated GHG
emissions using the site-specific process-vent-specific emission
factor, you must meet the requirements in paragraphs (c)(1) through
(c)(8) of this section.
    (1) Process vent testing. Conduct an emissions test every 5 years
that is based on representative performance (i.e., performance based on
the normal operating scenario) of the affected process. For each
continuous process vent, develop a process-vent-specific emission
factor for the representative operating scenario. For each batch
process vent, develop a process-vent-specific emission factor for the
representative operating scenario, i.e., the typical batch process.
Atypical events, such as process shutdowns or startups, may be included
in the monitoring for batch processes and may be included for
continuous process, if the monitoring is sufficiently long or
comprehensive to ensure that such events are not overrepresented in the
emission factor. Malfunction events shall not be included in the
monitoring.
    (2) Different operating conditions. Develop separate process-vent-
specific emission factor for other operating scenarios as needed. If
your process operates under different conditions as part of normal
operations, you must perform emission testing and develop separate
emission factors for these different process operating scenarios. For
continuous process vents, determine the emissions based on the process
activity at each specific different condition. For batch process vents,
determine emissions based on the process feed rate, process production
rate, or other process activity rate for each typical batch operating
scenario (i.e., each specific condition).
    (3) Number of runs. For continuous processes, sample the process
vent for a minimum of 3 runs of 1 hour each. For batch processes,
sample the process vent for all emission episodes over a minimum of 3
complete batch cycles. If the RSD of the emission factor

calculated based on the first 3 runs is greater than or equal to 0.2
for the emissions factor, continue to sample the process vent for an
additional 3 runs of 1 hour each or an additional 3 batch cycles. If
more than one fluorinated GHG is measured, and if all measured
fluorinated GHGs have GWPs listed in Table A-1, the emissions factor
and RSD shall be expressed in terms of total CO2
equivalents. Otherwise, the emissions factor and RSD shall be expressed
in terms of kilograms of each species.
    (4) Emission Test Methods. Conduct the emissions testing using the
following methods:
    (i) Sample and velocity traverses. Use EPA Method 1 or 1A in
Appendix A-1 of 40 CFR part 60.
    (ii) Velocity and volumetric flow rates. Use EPA Method 2, 2A, 2B,
2C, or 2D, 2F, or 2G in Appendix A-1 of 40 CFR part 60. Alternatives
that may be used for determining flow rates include Other Test Method
24 (OTM-24) (incorporated by reference, see Sec.  98.7) and Emission
Measurement Center Alternative Test Method (EMC ALT-012) (incorporated
by reference, see Sec.  98.7).
    (iii) Gas analysis. Use EPA Method 3, 3A, or 3B in Appendix A-1 of
40 CFR part 60.
    (iv) Stack gas moisture. Use EPA Method 4 in Appendix A-1 of 40 CFR
part 60.
    (v) Fluorinated GHG concentrations. Use EPA Method 18 (with GC and
either MS or ECD) in Appendix A-1 of 40 CFR part 60; EPA Method 320 in
Appendix A of 40 CFR part 63; Draft EPA DRE Protocol; or ASTM D6348-03
(incorporated by reference in Sec.  98.7).
    (vi) Alternative fluorinated GHG concentration methods.
Alternatives that may be used for determining fluorinated GHG
concentrations include EPA TO-15 or other alternative test methods
conducted in conjunction with EPA Method 301 for validation.
    (5) Process activity measurements. Determine the mass rate of
process feed, process production, or other process activity as
applicable during the test using flow meters, weigh scales, or other
measurement devices or instruments with an accuracy and precision of
1 percent of full scale or better. These devices may be the
same plant instruments or procedures that are used for accounting
purposes (such as weigh hoppers, belt weigh feeders, combination of
volume measurements and bulk density, etc.) if these devices or
procedures meet the requirement. For monitoring ongoing process
activity, use flow meters, weigh scales, or other measurement devices
or instruments with an accuracy and precision of 1 percent
of full scale or better.
    (6) Sample each process. If process vents from separate processes
are manifolded together to a common vent or to a common destruction
device, you must sample each process in the ducts before the emissions
are combined, sample when only one process is operating, or sample the
combined emissions at representative combinations of capacity
utilizations for all the processes. If the last option is selected, 3
times n test runs shall be required, where n is the number of processes
feeding into the common vent or destruction device, and the process-
vent-specific emission factor shall be applied whenever one or more of
the processes is operating. In this case, calculate the emission factor
for each sample by dividing the total emissions by the summed process
activity across the processes venting to the common vent. Derive the
process-vent-specific emission factor by averaging the 3n emission
factors.
    (7) Emission test results. The results of an emission test must
include the analysis of samples, determination of emissions, and raw
data. The emissions test report must contain all information and data
used to derive the process-vent-specific emission factor, as well as
key process conditions during the test. Key process conditions include
those that are normally monitored for process control purposes and may
include but are not limited to yields, pressures, temperatures, etc.
(e.g., of reactor vessels, distillation columns).
    (8) Previous measurements. If you have conducted an emissions test
less than 5 years before the effective date of this rule, and the
emissions testing meets the requirements in paragraph (c)(1) through
(7) of this section, you may use the previous emissions testing to
develop process-vent-specific emission factors.
    (d) Emission calculation factor monitoring. If you determine
fluorinated GHG emissions using the site-specific process-vent-specific
emission calculation factor, you must meet the requirements in
paragraphs (d)(1) through (d)(3) of this section.
    (1) Revise the emission calculation factor for each process every 5
years based on representative operation (i.e., performance based on the
normal operating scenario) of the affected process. For each continuous
process vent, develop the emission calculation factor for the
representative operating scenario. For each batch process vent, develop
the emission calculation factor for the representative operating
scenario, i.e., the typical batch process.
    (2) Different operating conditions. You must develop separate
emissions calculation factors for other operating scenarios as needed.
If your process operates under different conditions as part of normal
operations, you must conduct emissions calculations and develop
separate emission factors for these different process operating
scenarios. For continuous process vents, determine the emissions based
on the process activity at each specific different condition. For batch
process vents, determine emissions based on the process feed rate,
process production rate, or other process activity rate for each
typical batch operating scenario and for each non-typical batch
operating scenario (i.e., each specific condition).
    (3) Process activity measurements. Use flow meters, weigh scales,
or other measurement devices or instruments with an accuracy and
precision of 1 percent of full scale or better for
monitoring ongoing process activity.
    (e) Emission monitoring for pieces of equipment. Conduct the
screening level concentration measurements using EPA Method 21 in 40
CFR part 60, appendix A-7 to determine the screening level
concentration data or actual screening level concentration data for the
Screening Ranges Approach or the EPA Correlation Approach. Conduct the
screening level concentration measurements using EPA Method 21 and the
bagging procedures to measure mass emissions for developing the Unit-
Specific Correlation Approach in the Protocol for Equipment Leak
Emission Estimates, U.S. Environmental Protection Agency, EPA
Publication No. EPA-453/R-95-017, November 1995. Concentration
measurements of bagged samples must be conducted using gas
chromatography following EPA Method 18 analytical procedures. Use
methane as the calibration gas.
    (f) Destruction device performance testing. If you vent fluorinated
GHG emissions or otherwise feed fluorinated GHGs into a destruction
device and apply the destruction efficiency of the device in Sec.
98.123, you must conduct an emissions test every 5 years to determine
the destruction efficiency.
    (1) You must sample the inlet and outlet of the destruction device
for a minimum of three runs of 1 hour each to determine the destruction
efficiency. You must conduct the emissions testing using the methods in
paragraph (c)(4) of this section. To determine the destruction
efficiency, emission testing shall be conducted when operating at high
loads reasonably expected to occur (i.e., representative of high total
fluorinated GHG load that will be sent to the device) and when
destroying the

most-difficult-to-destroy fluorinated GHG (or a surrogate that is still
more difficult to destroy) that is fed into the device from the
processes subject to this subpart.
    (2) Previous testing. If you have conducted an emissions test
within the last 5 years prior to the effective date of this rule, and
the emissions testing meets the requirements in paragraph (f)(1) of
this section, you may use the destruction efficiency determined during
this previous emissions testing.
    (3) Part 264, 266, and 270 principal organic hazardous constituent
(POHC) testing. If a destruction device used to destroy fluorinated GHG
is subject to 40 CFR part 264 or 266 and is permitted under 40 CFR part
270 with a demonstrated DRE of at least 99.99 percent for the most-
difficult-to-destroy fluorinated GHG fed into the device from the
processes subject to this subpart, the emissions testing under
paragraph (f)(1) of this section is not required and you may use the
destruction efficiency determined during this previous testing.
    (4) Hazardous Waste Combustor testing. If a destruction device used
to destroy fluorinated GHG is subject to 40 CFR part 63, subpart EEE
and has a demonstrated DRE of at least 99.99 percent for the most-
difficult-to-destroy fluorinated GHG fed into the device from the
processes subject to this subpart, the emissions testing under
paragraph (f)(1) of this section is not required and you may use the
destruction efficiency determined during this previous testing.
    (5) Process change. For process changes that require a new or
revised operating scenario, you must determine whether the
concentrations and the fluorinated gas compounds vented to the
destruction device following the process change affects the DE (i.e.,
compare the post-process-change fluorinated GHG load and the most-
difficult-to-combust fluorinated GHG with the test conditions). If the
operating conditions and DE demonstrated in the destruction device
performance testing are not sufficient to achieve the DE for the
concentrations and fluorinated gas compounds vented to the destruction
device following the process change then, you must conduct another
emissions test to demonstrate the DE.
    (g) Mass of previously produced fluorinated GHGs fed into
destruction device. You must measure the mass of fluorinated GHGs that
are fed into the destruction device and that were previously produced
as defined at 98.410(b). Such fluorinated GHGs include but are not
limited to quantities that are shipped to the facility by another
facility for destruction and quantities that are returned to the
facility for reclamation but are found to be irretrievably contaminated
and are therefore destroyed. You must use flowmeters, weigh scales, or
a combination of volumetric and density measurements with an accuracy
and precision of 1 percent of full scale or better. If the measured
mass includes more than trace concentrations of materials other than
the fluorinated GHG being destroyed, you must measure the
concentrations of fluorinated GHG being destroyed. You must multiply
this concentration (mass fraction) by the mass measurement to obtain
the mass of the fluorinated GHG fed into the destruction device.
    (h) Emissions due to deviations of destruction device. In their
estimates of the mass of fluorinated GHG destroyed, fluorinated GHG
production facilities that destroy fluorinated GHGs shall account for
any temporary reductions in the destruction efficiency that result from
any malfunctions of the destruction device, including deviations from
the operating conditions defined in State or local permitting
requirements and/or oxidizer manufacturer specifications.
    (i) Emissions due to process startup, shutdown, or malfunctions.
Fluorinated GHG production facilities shall account for fluorinated GHG
emissions that occur as a result of startups, shutdowns, and
malfunctions, either recording fluorinated GHG emissions during these

fluorinated GHG emissions.
    (j) Initial scoping testing, emissions testing, and emissions
factor development must be completed by December 31, 2011.
    (k) Calibrate all flow meters, weigh scales, and combinations of

to the International System of Units (SI) through the National
Institute of Standards and Technology (NIST) or other recognized
national measurement institute. Recalibrate all flow meters, weigh
scales, and combinations of volumetric and density measures at the
minimum frequency specified by the manufacturer. Use any of the
following applicable flow meter test methods or the calibration
procedures specified by the flow meter, weigh-scale, or other
volumetric or density measure manufacturer.

    (l) All analytical equipment, including gas chromatographs, GC/MS,
GC/ECD, FTIR and NMR devices, used to determine the concentration of
fluorinated GHG in streams shall be calibrated at least monthly through
analysis of certified standards with known concentrations of the same
chemicals in the same ranges (fractions by mass) as the process
samples. Calibration gases prepared from a high-concentration certified
standard using a gas dilution system that meets the requirements
specified in Method 205, 40 CFR Part 51, Appendix M may also be used.
    (m) For calendar year 2011 monitoring, you may follow the
provisions of Sec.  98.3(d)(1) through (3) for best available
monitoring methods rather than follow the monitoring requirements of
this section. For purposes of subpart L, any reference to the year 2010
in Sec.  98.3(d)(1) through (3) shall mean 2011.

Sec.  98.125  Procedures for estimating missing data.

    (a) A complete record of all measured parameters used in the GHG
emissions calculations in Sec.  98.123 is required. Therefore, whenever
a quality-assured value of a required parameter is unavailable, a
substitute data value for the missing parameter shall be used in the
calculations as specified in paragraphs (b) and (c) of this section.
You must document and keep records of the procedures used for all such
estimates.

    (b) For each missing value of the fluorinated GHG concentration,
the substitute data value shall be the arithmetic average of the
quality-assured values of that parameter immediately preceding and
immediately following the missing data incident.
    (c) For each missing value of the mass produced, fed into the
production process, fed into the transformation process, fed into
destruction devices, sent to another facility for transformation, or
sent to another facility for destruction, the substitute value of that
parameter shall be a secondary mass measurement where such a
measurement is available. For example, if the mass produced is usually
measured with a flowmeter at the inlet to the day tank and that
flowmeter fails to meet an accuracy or precision test, malfunctions, or
is rendered inoperable, then the mass produced may be estimated by
calculating the change in volume in the day tank and multiplying it by
the density of the product. Where a secondary mass measurement is not
available, the substitute value of the parameter shall be an estimate
based on a related parameter. For example, if a flowmeter measuring the
mass fed into a destruction device is rendered inoperable, then the
mass fed into the destruction device may be estimated using the
production rate and the previously observed relationship between the
production rate and the mass flow rate into the destruction device.

Sec.  98.128  Definitions.

    Except as provided below, all of the terms used in this subpart
have the same meaning given in the Clean Air Act and subpart A of this
part. If a conflict exists between a definition provided in this
subpart and a definition provided in subpart A, the definition in this
subpart shall take precedence for the reporting requirements in this
subpart.
    Batch process or batch operation means a noncontinuous operation
involving intermittent or discontinuous feed into equipment, and, in
general, involves the emptying of the equipment after the batch
operation ceases and prior to beginning a new operation. Addition of
raw material and withdrawal of product do not occur simultaneously in a
batch operation.
    Batch emission episode means a discrete venting episode associated
with a vessel in a process; a vessel may have more than one batch
emission episode. For example, a displacement of vapor resulting from
the charging of a vessel with a feed material will result in a discrete
emission episode that will last through the duration of the charge and
will have an average flow rate equal to the rate of the charge. If the
vessel is then heated, there will also be another discrete emission
episode resulting from the expulsion of expanded vapor. Other emission
episodes also may occur from the same vessel and other vessels in the
process, depending on process operations.
    Completely destroyed means destroyed with a destruction efficiency
of 99.99 percent or greater.
    Completely recaptured means 99.99 percent or greater of each
fluorinated GHG is removed from a stream.
    Continuous process or operation means a process where the inputs
and

outputs flow continuously throughout the duration of the process.
Continuous processes are typically steady state.
    Destruction process means a process used to destroy fluorinated GHG
in a destruction device such as a thermal incinerator or catalytic
oxidizer.
    Equipment (for the purposes of 40 CFR part 98, subpart L only)
means each pump, compressor, agitator, pressure relief device, sampling
connection system, open-ended valve or line, valve, connector, and
instrumentation system in fluorinated GHG service for a process subject
to this subpart; and any destruction devices or closed-vent systems to
which processes subject to this subpart are vented.
    Fluorinated gas means any fluorinated GHG, CFC, or HCFC.
    In fluorinated GHG service means that a piece of equipment either
contains or contacts a feedstock, byproduct, or product that contains
fluorinated GHG.
    Isolated intermediate means a product of a process that is stored
before subsequent processing. An isolated intermediate is usually a
product of chemical synthesis. Storage of an isolated intermediate
marks the end of a process. Storage occurs at any time the intermediate
is placed in equipment used solely for storage.
    Operating scenario means any specific operation of a process and
includes for each process: (1) A description of the process and the
specific process equipment used; (2) An identification of related
process vents, their associated emissions episodes and durations, and
calculations and engineering analyses to show the annual uncontrolled
fluorinated GHG emissions from the process vent; (3) The control or
destruction devices used, as applicable, including a description of
operating and/or testing conditions for any associated destruction
device; (4) The process vents (including those from other processes)
that are simultaneously routed to the control or destruction device(s);
and (5) The applicable monitoring requirements and any parametric level
that assures destruction or removal for all emissions routed to the
control or destruction device. A change to any of these elements not
previously reported, except for item (4) of this definition, shall
constitute a different operating scenario.
    Process means all equipment which collectively function to produce
a fluorinated gas product, including an isolated intermediate (which is
also a fluorinated gas product), or to transform a fluorinated gas
product. A process may consist of one or more unit operations. For the
purposes of this subpart, process includes any, all, or a combination
of reaction, recovery, separation, purification, or other activity,
operation, manufacture, or treatment which are used to produce a
fluorinated gas product. For a continuous process, cleaning operations
conducted may be considered part of the process, at the discretion of
the facility. For a batch process, cleaning operations are part of the
process. Ancillary activities are not considered a process or part of
any process under this subpart. Ancillary activities include boilers
and incinerators, chillers and refrigeration systems, and other
equipment and activities that are not directly involved (i.e., they
operate within a closed system and materials are not combined with
process fluids) in the processing of raw materials or the manufacturing
of a fluorinated gas product.
    Process condenser means a condenser whose primary purpose is to
recover material as an integral part of a process. All condensers
recovering condensate from a process vent at or above the boiling point
or all condensers in line prior to a vacuum source are considered
process condensers. Typically, a primary condenser or condensers in
series are considered to be integral to the process if they are capable
of and normally used for the purpose of recovering chemicals for fuel
value (i.e., net positive heating value), use, reuse or for sale for
fuel value, use, or reuse.
    Process vent (for the purposes of 40 CFR part 98, subpart L only)
means a vent from a process vessel or vents from multiple process
vessels within a process that are manifolded together into a common
header, through which a fluorinated GHG-containing gas stream is, or
has the potential to be, released to the atmosphere. Examples of
process vents include, but are not limited to, vents on condensers used
for product recovery, bottoms receivers, surge control vessels,
reactors, filters, centrifuges, and process tanks. Process vents do not
include vents on storage tanks or pieces of equipment.
    Typical batch means a batch process operated within a range of
operating conditions that are documented in an operating scenario.
Emissions from a typical batch are based on the operating conditions
that result in representative emissions. The typical batch defines the
uncontrolled emissions for each emission episode defined under the
operating scenario.
    Uncontrolled fluorinated GHG emissions means a gas stream
containing fluorinated GHG which has exited the process (or process
condenser, where applicable), but which has not yet been introduced
into a destruction device to reduce the mass of fluorinated GHG in the
stream. If the emissions from the process are not routed to a
destruction device, uncontrolled emissions are those fluorinated GHG
emissions released to the atmosphere.

Subpart SS--Sulfur Hexafluoride and Perfluorocarbons From
Electrical Equipment Manufacture or Refurbishment

Sec.  98.450  Definition of the source category.

    The electrical equipment manufacturing category consists of
processes that manufacture or refurbish gas-insulated substations,
circuit breakers, other switchgear, gas-insulated lines, or power
transformers (including gas-containing components of such equipment)
containing sulfur-hexafluoride (SF6) or perfluorocarbons
(PFCs).

Sec.  98.451  Reporting threshold.

    You must report GHG emissions under this subpart if your facility
contains an electrical equipment manufacturing process and the facility
meets the requirements of either Sec.  98.2(a)(1) or (a)(2).

Sec.  98.452  GHGs to report.

    (a) You must report annual SF6 and PFC emissions
(including emissions from equipment testing, manufacturing,
decommissioning and disposal, refurbishing, and from storage cylinders
and other containers) from any facility associated with the manufacture
or refurbishment of closed-pressure and sealed-pressure equipment
(including components of such equipment).
    (b) You must report CO2, N2O and
CH4 combustion-related emissions from each stationary
combustion unit. You must calculate and report these emissions under
subpart C of this part (General Stationary Fuel Combustion Sources) by
following the requirements of subpart C.

Sec.  98.453  Calculating GHG emissions.

    (a) For each electrical equipment manufacturer, you must estimate
the annual SF6 and PFC emissions using the mass-balance
approach in Equation SS-1 of this section:
[GRAPHIC] [TIFF OMITTED] TP12AP10.078

Where:

    Decrease in SF6 Inventory = (SF6 stored in
containers at the beginning of the year)--(SF6 stored in
containers at the end of the year).
    Acquisitions of SF6 = (SF6 purchased from
chemical producers or distributors in bulk) + (SF6
returned by equipment users or distributors in equipment or
containers) + (SF6 returned to site after off-site
recycling).
    Disbursements of SF6 = (SF6 contained in
new equipment delivered to customers) + (SF6 delivered to
equipment users in containers) + (SF6 returned to
suppliers) + (SF6 sent off site for recycling) +
(SF6 sent to destruction facilities).

    (b) The mass-balance method in paragraph (a) of this section shall
be used to estimate emissions of PFCs associated with the manufacture
or refurbishment of power transformers, substituting the relevant
PFC(s) for SF6 in Equation SS-1.
    (c) The disbursements of SF6 or PFCs to customers in new
equipment or cylinders shall be estimated using Equation SS-2 of this
section:
[GRAPHIC] [TIFF OMITTED] TP12AP10.079

Where:

    DGHG = The disbursement of SF6 or PFCs
over the period to customers in new equipment or cylinders.
    Qp = The mass of the SF6 or PFCs charged
into equipment or containers over the period p sent to customers or
sent off-site for other purposes including for recycling, for
destruction or to be returned to suppliers.
    n = The number of periods in the year.

    (d) The mass of SF6 or PFCs disbursed to customers in
new equipment or cylinders over the period p may be estimated by
monitoring the mass flow of the SF6 or PFCs into the new
equipment or cylinders using a flow meter or by weighing containers
before and after gas from containers is used to fill equipment or
cylinders.
    (e) If the mass of SF6 or the PFC disbursed to customers
in new equipment or cylinders over the period p is estimated by
weighing containers before and after gas from containers is used to
fill equipment or cylinders, this quantity shall be estimated by using
Equation SS-3 of this section:
[GRAPHIC] [TIFF OMITTED] TP12AP10.080

Where:

    Qp = The mass of SF6 or the PFC disbursed
to customers over the period p.
    MB = The mass of the contents of the containers used
to fill equipment or cylinders at the beginning of period p.
    ME = The mass of the contents of the containers used
to fill equipment or cylinders at the end of period p.
    EL = The mass of SF6 or the PFC emitted
during the period p downstream of the containers used to fill
equipment or cylinders (e.g., emissions from hoses or other flow
lines that connect the container to the equipment or cylinder that
is being filled).

    (f) If the mass of SF6 or the PFC disbursed to customers
in new equipment or cylinders over the period p is determined using a
flow meter, this quantity shall be estimated using Equation SS-4 of
this section:
[GRAPHIC] [TIFF OMITTED] TP12AP10.081

Where:

    Qp = The mass of SF6 or the PFC disbursed
to customers over the period p.
    Mmr = The mass of the SF6 or the PFC that
has flowed through the flow meter during the period p.
    EL = The mass of SF6 or the PFC emitted
downstream of the flowmeter during the period p (e.g., emissions
from hoses or other flow lines that connect the container to the
equipment that is being filled).

Sec.  98.454  Monitoring and QA/QC requirements.

    (a) For calendar year 2011 monitoring, you may follow the
provisions of Sec.  98.3(d)(1) through (d)(3) for best available
