use, in place of the term Cij in each equation, the total
consumption of each fluorinated GHG

meeting the criteria in paragraph (i)(4)(i) of this section or that is
used in tools vented to the stack systems that meet the criteria in
paragraph (i)(4)(ii) of this section. You must use, in place of the
term aij, the fraction of fluorinated GHG meeting the
criteria in paragraph (i)(4)(i) of this section used in tools with
abatement systems or that is used in tools with abatement systems that
are vented to the stack systems that meet the criteria in paragraph

I-24A and I-24B of this subpart in place of the terms dij in
Equation I-8 and djk in Equation I-9, respectively, and use
the results of Equation I-23 of this subpart in place of the results of
Equation I-15 of this subpart for the term UTij.

27. Amend Sec.  98.94 by revising paragraphs (f) introductory text and
(j)(5)(ii) introductory text to read as follows:

Sec.  98.94  Monitoring and QA/QC requirements.

* * * * *
    (f) If your fab employs abatement systems and you elect to reflect
emission reductions due to these systems, or if your fab employs
abatement systems designed for fluorinated GHG abatement and you elect
to calculate fluorinated GHG emissions using the stack test method
under Sec.  98.93(i), you must comply with the requirements of
paragraphs (f)(1) through (3) of this section. If you use an average of
properly measured destruction or removal efficiencies for a gas and
process sub-type or process type combination, as applicable, in your
emission calculations under Sec.  98.93(a), (b), and/or (i), you must
also adhere to procedures in paragraph (f)(4) of this section.
* * * * *
    (j) * * *
    (5) * * *
    (ii) Criteria to test less frequently. After the first 3 years of
annual testing, you may calculate the relative standard deviation of
the emission factors for each fluorinated GHG included in the test and
use that analysis to determine the frequency of any future testing. As
an alternative, you may conduct all three tests in less than 3 calendar
years for purposes of this paragraph (j)(5)(ii), but this does not
relieve you of the obligation to conduct subsequent annual testing if
you do not meet the criteria to test less frequently. If the criteria
specified in paragraphs (j)(5)(ii)(A) and (B) of this section are met,
you may use the arithmetic average of the three emission factors for
each fluorinated GHG and fluorinated GHG byproduct for the current year
and the next 4 years with no further testing unless your fab operations
are changed in a way that triggers the re-test criteria in paragraph
(j)(8) of this section. In the fifth year following the last stack test
included in the previous average, you must test each of the stack
systems for which testing is required and repeat the relative standard
deviation analysis using the results of the most recent three tests
(i.e., the new test and the two previous tests conducted prior to the
4-year period). If the criteria specified in paragraphs (j)(5)(ii)(A)
and (B) of this section are not met, you must use the emission factors
developed from the most recent testing and continue annual testing. You
may conduct more than one test in the same year, but each set of
emissions testing for a stack system must be separated by a period of
at least 2 months. You may repeat the relative standard deviation
analysis using the most recent three tests, including those tests
conducted prior to the 4-year period, to determine if you are exempt
from testing for the next 4 years.

estimate CO2 emissions that would result from the complete
combustion or oxidation of the natural gas received at the city gate
(including natural gas that is transported by, but not owned by, the
reporter) using Equation NN-1 of this section. For each product, use
the default value for higher heating value and CO2 emission
factor in Table NN-1 of this subpart. Alternatively, for each product,
a reporter-specific higher heating value and CO2 emission
factor may be used, in place of one or both defaults provided they are
developed using methods outlined in Sec.  98.404. For each product, you

transfer fluids do not include fluorinated GHGs used as lubricants or
surfactants. For fluorinated heat transfer fluids under this subpart,
the lower vapor pressure limit of 1 mm Hg in absolute at 25 [deg]C in
the definition of fluorinated greenhouse gas in Sec.  98.6 shall not
apply. Fluorinated heat transfer fluids include, but are not limited
to, perfluoropolyethers, perfluoroalkanes, perfluoroethers, tertiary
perfluoroamines, and perfluorocyclic ethers. Producing a fluorinated
HTF does not include the reuse or recycling of a fluorinated HTF, the
creation of intermediates, or the creation of fluorinated HTFs that are
released or destroyed at the production facility before the production
measurement at Sec.  98.414(a).
    (e) For purposes of this subpart, to destroy fluorinated GHGs or
fluorinated HTFs means to cause the expiration of a previously produced
(as defined in paragraphs (b) and (d) of this section) fluorinated GHG
or fluorinated HTF to the destruction efficiency actually achieved.
Such destruction does not result in a commercially useful end product.
For purposes of this subpart, such destruction does not include HFC-23
destruction as defined at Sec.  98.150 or the dissociation of
fluorinated GHGs that occurs during electronics manufacturing as
defined at Sec.  98.90. For example, such destruction does not include
the dissociation of fluorinated GHGs that occurs during etch or chamber
cleaning processes or during use of abatement systems that treat the
fluorinated GHGs vented from such processes at electronics
manufacturing facilities.

87. Effective January 1, 2018, amend Sec.  98.414 by revising
paragraphs (a) through (i), (l), (n) introductory text, (n)(3) through
(5), and (o) to read as follows:

Sec.  98.414  Monitoring and QA/QC requirements.

    (a) The mass of fluorinated GHGs, fluorinated HTFs, or nitrous
oxide coming out of the production process shall be measured using
flowmeters, weigh scales, or a combination of volumetric and density
measurements with an accuracy and precision of one percent of full
scale or better. If the measured mass includes more than one
fluorinated GHG or fluorinated HTF, the concentrations of each of the
fluorinated GHGs or fluorinated HTFs, other than low-concentration
constituents, shall be measured as set forth in paragraph (n) of this
section. For each fluorinated GHG or fluorinated HTF, the mean of the
concentrations of that fluorinated GHG (mass fraction) measured under
paragraph (n) shall be multiplied by the mass measurement to obtain the
mass of that fluorinated GHG or fluorinated HTF coming out of the
production process.
    (b) The mass of any used fluorinated GHGs, fluorinated HTFs, or
used nitrous oxide added back into the production process upstream of
the output measurement in paragraph (a) of this section shall be
measured using flowmeters, weigh scales, or a combination of volumetric
and density measurements with an accuracy and precision of one percent
of full scale or better. If the mass in paragraph (a) is measured by
weighing containers that include returned heels as well as newly
produced fluorinated GHGs or fluorinated HTFs, the returned heels shall
be considered used fluorinated GHGs or fluorinated HTFs for purposes of
this paragraph (b) and Sec.  98.413(b).
    (c) The mass of fluorinated GHGs, fluorinated HTFs, or nitrous
oxide fed into the transformation process shall be measured using
flowmeters, weigh scales, or a combination of volumetric and density
measurements with an accuracy and precision of one percent of full
scale or better.
    (d) The fraction of the fluorinated GHGs, fluorinated HTFs, or
nitrous oxide fed into the transformation process that is actually
transformed shall be estimated considering yield calculations or
quantities of unreacted fluorinated GHGs, fluorinated HTFs, or nitrous
oxide permanently removed from the process and recovered, destroyed, or
emitted.
    (e) The mass of fluorinated GHGs, fluorinated HTFs, or nitrous
oxide sent to another facility for transformation shall be measured
using flowmeters, weigh scales, or a combination of volumetric and
density measurements with an accuracy and precision of one percent of
full scale or better.
    (f) The mass of fluorinated GHGs or fluorinated HTFs sent to
another facility for destruction shall be measured using flowmeters,
weigh scales, or a combination of volumetric and density measurements
with an accuracy and precision of one percent of full scale or better.
If the measured mass includes more than trace concentrations of
materials other than the fluorinated GHG or fluorinated HTF, the
concentration of the fluorinated GHG or fluorinated HTF shall be
estimated considering current or previous representative concentration
measurements and other relevant process information. This concentration
(mass fraction) shall be multiplied by the mass measurement to obtain
the mass of the fluorinated GHG or fluorinated HTF sent to another
facility for destruction.
    (g) You must estimate the share of the mass of fluorinated GHGs or
fluorinated HTFs in paragraph (f) of this section that is comprised of
fluorinated GHGs or fluorinated HTFs that are not included in the mass
produced in Sec.  98.413(a) because they are removed from the
production process as by-products or other wastes.
    (h) You must measure the mass of each fluorinated GHG or
fluorinated HTF that is fed into the destruction device and that was
previously produced as defined at Sec.  98.410(b). Such fluorinated
GHGs or fluorinated HTFs 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 one percent of
full scale or better. If the measured mass includes more than trace
concentrations of materials other than the fluorinated GHG or
fluorinated HTF being destroyed, you must estimate the concentrations
of the fluorinated GHG or fluorinated HTF being destroyed considering
current or previous representative concentration measurements and other
relevant process information. You must multiply this concentration
(mass fraction) by the mass measurement to obtain the mass of the
fluorinated GHG or fluorinated HTF fed into the destruction device.
    (i) Very small quantities of fluorinated GHGs or fluorinated HTFs
that are difficult to measure because they are entrained in other media
such as destroyed filters and destroyed sample containers are exempt
from paragraphs (f) and (h) of this section.
* * * * *
    (l) In their estimates of the mass of fluorinated GHGs or
fluorinated HTFs destroyed, facilities that destroy fluorinated GHGs or
fluorinated HTFs shall account for any temporary reductions in the
destruction efficiency that result from any startups, shutdowns, or
malfunctions of the destruction device, including departures from the
operating conditions defined in state or local permitting requirements
and/or oxidizer manufacturer specifications.
* * * * *
    (n) If the mass coming out of the production process includes more
than one fluorinated GHG or fluorinated HTF, you shall measure the
concentrations of all of the fluorinated GHGs or fluorinated HTFs,
other than low-concentration constituents, as follows:
* * * * *
    (3) Frequency of measurement. Perform the measurements at least
once by February 15, 2011 if the fluorinated GHG product is being
produced on December 17, 2010. Perform the measurements within 60 days
of commencing production of any fluorinated GHG product that was not
being produced on December 17, 2010. For fluorinated HTF products that
are not also fluorinated GHG products, perform the measurements at
least once by February 28, 2018, if the fluorinated HTF product is
being produced on January 1, 2018. Perform the measurements within 60
days of commencing production of any fluorinated HTF product that was
not being produced on January 1, 2018. Repeat the measurements if an
operational or process change occurs that could change the identities
or significantly change the concentrations of the fluorinated GHG or
fluorinated HTF constituents of the fluorinated GHG or fluorinated HTF
product. Complete the repeat measurements within 60 days of the
operational or process change.
    (4) Measure all product grades. Where a fluorinated GHG or
fluorinated HTF is produced at more than one purity level (e.g.,
pharmaceutical grade and refrigerant grade), perform the measurements
for each purity level.
    (5) Number of samples. Analyze a minimum of three samples of the
fluorinated GHGs or fluorinated HTF product that have been drawn under
conditions that are representative of the process producing the
fluorinated GHGs or fluorinated HTF product. If the

relative standard deviation of the measured concentrations of any of
the fluorinated GHGs or fluorinated HTF constituents (other than low-
concentration constituents) is greater than or equal to 15 percent,
draw and analyze enough additional samples to achieve a total of at
least six samples of the fluorinated GHG or fluorinated HTF product.
    (o) All analytical equipment used to determine the concentration of
fluorinated GHGs or fluorinated HTFs, including but not limited to gas
chromatographs and associated detectors, IR, FTIR and NMR devices,
shall be calibrated at a frequency needed to support the type of
analysis specified in the site GHG Monitoring Plan as required under
paragraph (n) of this section and Sec.  98.3(g)(5). Quality assurance
samples at the concentrations of concern shall be used for the
calibration. Such quality assurance samples shall consist of or be
prepared from certified standards of the analytes of concern where
available; if not available, calibration shall be performed by a method
specified in the GHG Monitoring Plan.

\a\ The applicable climate classification is determined based on the annual rainfall plus the recirculated
  leachate application rate. Recirculated leachate application rate (in inches/year) is the total volume of
  leachate recirculated from company records or engineering estimates and applied to the landfill divided by the
  area of the portion of the landfill containing waste [with appropriate unit conversions].
Dry climate = precipitation plus recirculated leachate less than 20 inches/year;
Moderate climate = precipitation plus recirculated leachate from 20 to 40 inches/year (inclusive);
Wet climate = precipitation plus recirculated leachate greater than 40 inches/year.
Alternatively, landfills that use leachate recirculation can elect to use the k value for wet climate rather
  than calculating the recirculated leachate rate.
\b\ Kraft Recovery Wastes include green liquor dregs, slaker grits, and lime mud, which may also be referred to
  collectively as causticizing or recausticizing wastes.
\c\ A facility that can segregate out pulp and paper industry wastewater sludge must apply the 0.12 DOC value to
  that portion of the sludge.
