                               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, 2023), 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 dropped in 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.
    An index to the text of ``Title 3--The President'' is carried within 
that volume.

[[Page vii]]

    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.

gas or fuel oil (as defined in Sec. 75.2 of this chapter) during a 
control period includes a NOX emission limitation restricting 
NOX emissions during a control period to 25 tons or less, and 
includes the special provisions in paragraph (b)(4) of this section 
shall be exempt from the requirements of the NOX Budget 
Trading Program, except for the provisions of this paragraph (b), Sec. 
97.2, Sec. 97.3, Sec. 97.4(a), Sec. 97.7, and subparts E, F, and G of 
this part. The NOX emission limitation under this paragraph 
(b)(1) shall restrict NOX emissions during the control period 
by limiting unit operating hours. The restriction on unit operating 
hours shall be calculated by dividing 25 tons by the unit's maximum 
potential hourly NOX mass emissions, which shall equal the 
unit's maximum rated hourly heat input multiplied by the highest default 
NOX emission rate otherwise applicable to the unit under 
Sec. 75.19 of this chapter.
    (2) The exemption under paragraph (b)(1) of this section shall 
become effective as follows:
    (i) The exemption shall become effective on the date on which the 
NOX emission limitation and the special provisions in the 
permit under paragraph (b)(1) of this section become final; or
    (ii) If the NOX emission limitation and the special 
provisions in the permit under paragraph (b)(1) of this section become 
final during a control period and after the first date on which the unit 
operates during such control period, then the exemption shall become 
effective on May 1 of such control period, provided that such 
NOX emission limitation and the special provisions apply to 
the unit as of such first date of operation. If such NOX 
emission limitation and special provisions do not apply to the unit as 
of such first date of operation, then the exemption under paragraph 
(b)(1) of this section shall become effective on October 1 of the year 
during which such NOX emission limitation and the special 
provisions become final.
    (3) The permitting authority that issues a federally enforceable 
permit under paragraph (b)(1) of this section for a unit under paragraph 
(a)(1) or (a)(2) of this section will provide the Administrator written 
notice of the issuance of such permit and, upon request, a copy of the 
permit.
    (4) Special provisions. (i) A unit exempt under paragraph (b)(1) of 
this section shall comply with the restriction on fuel use and unit 
operating hours described in paragraph (b)(1) of this section during the 
control period in each year.
    (ii) The Administrator will allocate NOX allowances to 
the unit under Sec. Sec. 97.41(a) through (c) and 97.42(a) through (c). 
For each control period for which the unit is allocated NOX 
allowances under Sec. Sec. 97.41(a) through (c) and 97.42(a) through 
(c):
    (A) The owners and operators of the unit must specify a general 
account, in which the Administrator will record the NOX 
allowances; and
    (B) After the Administrator records a NOX allowance 
allocations under Sec. Sec. 97.41(a) through (c) and 97.42(a) through 
(c), the Administrator will deduct, from the general account under 
paragraph (b)(4)(ii)(A) of this section, NOX allowances that 
are allocated for the same or a prior control period as the 
NOX allowances allocated to the

[[Page 20]]

unit under Sec. Sec. 97.41(a) through (c) and 97.42(a) through (c) and 
that equal the NOX emission limitation (in tons of 
NOX) on which the unit's exemption under paragraph (b)(1) of 
this section is based. The NOX authorized account 
representative shall ensure that such general account contains the 
NOX allowances necessary for completion of such deduction.
    (iii) A unit exempt under this paragraph (b) shall report hours of 
unit operation during the control period in each year to the permitting 
authority by November 1 of that year.
    (iv) For a period of 5 years from the date the records are created, 
the owners and operators of a unit exempt under paragraph (b)(1) of this 
section shall retain, at the source that includes the unit, records 
demonstrating that the conditions of the federally enforceable permit 
under paragraph (b)(1) of this section were met, including the 
restriction on fuel use or unit operating hours. The 5-year period for 
keeping records may be extended for cause, at any time prior to the end 
of the period, in writing by the permitting authority or the 
Administrator. The owners and operators bear the burden of proof that 
the unit met the restriction on fuel use or unit operating hours.
    (v) The owners and operators and, to the extent applicable, the 
NOX authorized account representative of a unit exempt under 
paragraph (b)(1) of this section shall comply with the requirements of 
the NOX Budget Trading Program concerning all periods for 
which the exemption is not in effect, even if such requirements arise, 
or must be complied with, after the exemption takes effect.
    (vi) On the earlier of the following dates, a unit exempt under 
paragraph (b)(1) of this section shall lose its exemption:
    (A) The date on which the restriction on fuel use or unit operating 
hours described in paragraph (b)(1) of this section is removed from the 
unit's federally enforceable permit or otherwise becomes no longer 
applicable to any control period starting in 2004; or
    (B) The first date on which the unit fails to comply, or with regard 
to which the owners and operators fail to meet their burden of proving 
that the unit is complying, with the restriction on fuel use or unit 
operating hours described in paragraph (b)(1) of this section during any 
control period starting in 2004.
    (vii) A unit that loses its exemption in accordance with paragraph 
(b)(4)(vi) of this section shall be subject to the requirements of this 
part. For the purpose of applying permitting requirements under subpart 
C of this part, allocating allowances under subpart E of this part, and 
applying monitoring requirements under subpart H of this part, the unit 
shall be treated as commencing operation and, if the unit is covered by 
paragraph (a)(1) of this section, commencing commercial operation on the 
date the unit loses its exemption.
    (viii) A unit that is exempt under paragraph (b)(1) of this section 
is not eligible to be a NOX Budget opt-in unit under subpart 
I of this part.

Sec. 97.42  NOX allowance allocations.

    (a)(1) The heat input (in mmBtu) used for calculating NOX 
allowance allocations for each NOX Budget unit under Sec. 
97.4(a) will be:
    (i) For a NOX allowance allocation under Sec. 97.41(a):
    (A) For a unit under Sec. 97.4(a)(1), the average of the two 
highest amounts of the unit's heat input for the control periods in 1995 
through 1998; or
    (B) For a unit under Sec. 97.4(a)(2), the control period in 1995 
or, if the Administrator determines that reasonably reliable data are 
available for control periods in 1996 through 1998, the average of the 
two highest amounts of the unit's heat input for the control periods in 
1995 through 1998.
    (ii) For a NOX allowance allocation under Sec. 97.41(b), 
the unit's average heat input for the control periods in 2002 through 
2004.
    (iii) For a NOX allowance allocation under Sec. 
97.41(c), the unit's average heat input for the control period in the 
years that are 4, 5, 6, 7, and 8 years before the first year for which 
the allocation is being calculated.
    (2) The unit's heat input for the control period in each year 
specified under paragraph (a)(1) of this section will be determined in 
accordance with part 75 of this chapter. Notwithstanding the first 
sentence of this paragraph (a)(2):
    (i) For a NOX allowance allocation under Sec. 97.41(a), 
such heat input will be determined using the best available data 
reported to the Administrator for the unit if the unit was not otherwise 
subject to the requirements of part 75 of this chapter for the control 
period.
    (ii) For a NOX allowance allocation under Sec. 97.41(b) 
or (c) for a unit exempt under Sec. 97.4(b), such heat input shall be 
treated as zero if the unit is exempt under Sec. 97.4(b) during the 
control period.
    (b) For each group of control periods specified in Sec. 97.41(a) 
through (c), the Administrator will allocate to all NOX 
Budget units in a given State under Sec. 97.4(a)(1) that commenced 
operation before May 1, 1997 for allocations under Sec. 97.41(a), May 
1, 2003 for allocations under Sec. 97.41(b), and May 1 of the year 5 
years before the first year for which the allocation under Sec. 
97.41(c) is being calculated, a total number of NOX 
allowances equal to 95 percent of the portion of the State's trading 
program budget under Sec. 97.40 covering such units. The Administrator 
will allocate in accordance with the following procedures:
    (1) The Administrator will allocate NOX allowances to 
each NOX Budget unit under Sec. 97.4(a)(1) for each control 
period in an amount equaling 0.15 lb/mmBtu multiplied by the heat input 
determined under paragraph (a) of this section, divided by 2,000 lb/ton, 
and rounded to the nearest whole number of NOX allowances as 
appropriate.
    (2) If the initial total number of NOX allowances 
allocated to all NOX Budget units under Sec. 97.4(a)(1) in 
the State for a control period under paragraph (b)(1) of this section 
does not equal 95 percent of the portion of the State's trading program 
budget under Sec. 97.40 covering such units, the Administrator will 
adjust the total number of NOX allowances allocated to all 
such NOX Budget units for the control period under paragraph 
(b)(1) of this section so that the total number of NOX 
allowances allocated equals 95 percent of such portion of the State's 
trading program budget. This adjustment will be made by: multiplying 
each unit's allocation by 95 percent of such portion of the State's 
trading program budget; dividing by the total number of NOX 
allowances allocated under paragraph (b)(1) of this section for the 
control period; and rounding to the nearest whole number of 
NOX allowances as appropriate.
    (c) For each group of control periods specified in Sec. 97.41(a) 
through (c), the Administrator will allocate to all NOX 
Budget units in a given State under Sec. 97.4(a)(2) that commenced 
operation before May 1, 1997 for allocations under Sec. 97.41(a), May 
1, 2003 for allocations under Sec. 97.41(b), and May 1 of the year 5 
years before the first year for which the allocation under Sec. 
97.41(c) is being

[[Page 31]]

calculated, a total number of NOX allowances equal to 95 
percent of the portion of the State's trading program budget under Sec. 
97.40 covering such units. The Administrator will allocate in accordance 
with the following procedures:
    (1) The Administrator will allocate NOX allowances to 
each NOX Budget unit under Sec. 97.4(a)(2) for each control 
period in an amount equaling 0.17 lb/mmBtu multiplied by the heat input 
determined under paragraph (a) of this section, divided by 2,000 lb/ton, 
and rounded to the nearest whole number of NOX allowances as 
appropriate.
    (2) If the initial total number of NOX allowances 
allocated to all NOX Budget units under Sec. 97.4(a)(2) in 
the State for a control period under paragraph (c)(1) of this section 
does not equal 95 percent of the portion of the State's trading program 
budget under Sec. 97.40 covering such units, the Administrator will 
adjust the total number of NOX allowances allocated to all 
such NOX Budget units for the control period under paragraph 
(a)(1) of this section so that the total number of NOX 
allowances allocated equals 95 percent of the portion of the State's 
trading program budget under Sec. 97.40 covering such units. This 
adjustment will be made by: multiplying each unit's allocation by 95 
percent of the portion of the State's trading program budget under Sec. 
97.40 covering such units; dividing by the total number of 
NOX allowances allocated under paragraph (c)(1) of this 
section for the control period; and rounding to the nearest whole number 
of NOX allowances as appropriate.
    (d) For each control period specified in Sec. 97.41(d), the 
Administrator will allocate NOX allowances to NOX 
Budget units in a given State under Sec. 97.4(a) (except for units 
exempt under Sec. 97.4(b)) that commence operation, or are projected to 
commence operation, on or after: May 1, 1997 (for control periods under 
Sec. 97.41(a)); May 1, 2003, (for control periods under Sec. 
97.41(b)); and May 1 of the year 5 years before the beginning of the 
group of 5 years that includes the control period (for control periods 
under Sec. 97.41(c)). The Administrator will make the allocations under 
this paragraph (d) in accordance with the following procedures:
    (1) The Administrator will establish one allocation set-aside for 
each control period. Each allocation set-aside will be allocated 
NOX allowances equal to 5 percent of the tons of 
NOX emission in the State's trading program budget under 
Sec. 97.40, rounded to the nearest whole number of NOX 
allowances as appropriate.
    (2) The NOX authorized account representative of a 
NOX Budget unit specified in this paragraph (d) may submit to 
the Administrator a request, in a format specified by the Administrator, 
to be allocated NOX allowances for the control period. The 
NOX allowance allocation request must be received by the 
Administrator on or after the date on which the State permitting 
authority issues a permit to construct the unit and by January 1 before 
the control period for which NOX allowances are requested.
    (3) In a NOX allowance allocation request under paragraph 
(d)(2) of this section, the NOX authorized account 
representative for a NOX Budget unit under Sec. 97.4(a)(1) 
may request for the control period NOX allowances in an 
amount that does not exceed the lesser of:
    (i) 0.15 lb/mmBtu multiplied by the unit's maximum design heat 
input, multiplied by the lesser of 3,672 hours or the number of hours 
remaining in the control period starting with the day in the control 
period on which the unit commences operation or is projected to commence 
operation, divided by 2,000 lb/ton, and rounded to the nearest whole 
number of NOX allowances as appropriate; or
    (ii) The unit's most stringent State or Federal NOX 
emission limitation multiplied by the unit's maximum design heat input, 
multiplied by the lesser of 3,672 hours or the number of hours remaining 
in the control period starting with the day in the control period on 
which the unit commences operation or is projected to commence 
operation, divided by 2,000 lb/ton, and rounded to the nearest whole 
number of NOX allowances as appropriate.
    (4) In a NOX allowance allocation request under paragraph 
(d)(2) of this section, the NOX authorized account 
representative for a NOX Budget unit under Sec. 97.4(a)(2) 
may request for the

[[Page 32]]

control period NOX allowances in an amount that does not 
exceed the lesser of:
    (i) 0.17 lb/mmBtu multiplied by the unit's maximum design heat 
input, multiplied by the lesser of 3,672 hours or the number of hours 
remaining in the control period starting with the day in the control 
period on which the unit commences operation or is projected to commence 
operation, divided by 2,000 lb/ton, and rounded to the nearest whole 
number of NOX allowances as appropriate; or
    (ii) The unit's most stringent State or Federal NOX 
emission limitation multiplied by the unit's maximum design heat input, 
multiplied by the lesser of 3,672 hours or the number of hours remaining 
in the control period starting with the day in the control period on 
which the unit commences operation or is projected to commence 
operation, divided by 2,000 lb/ton, and rounded to the nearest whole 
number of NOX allowances as appropriate.
    (5) The Administrator will review each NOX allowance 
allocation request submitted in accordance with paragraph (d)(2) of this 
section and will allocate NOX allowances pursuant to such 
request as follows:
    (i) Upon receipt of the NOX allowance allocation request, 
the Administrator will make any necessary adjustments to the request to 
ensure that the requirements of paragraphs (d) introductory text, 
(d)(2), (d)(3), and (d)(4) are met.
    (ii) The Administrator will determine the following amounts:
    (A) The sum of the NOX allowances requested (as adjusted 
under paragraph (d)(5)(i) of this section) in all NOX 
allowance allocation requests under paragraph (d)(2) of this section for 
the control period; and
    (B) For units exempt under Sec. 97.4(b) in the State that commenced 
operation, or are projected to commence operation, on or after May 1, 
1997 (for control periods under Sec. 97.41(a)); May 1, 2003, (for 
control periods under Sec. 97.41(b)); and May 1 of the year 5 years 
before beginning of the group of 5 years that includes the control 
period (for control periods under Sec. 97.41(c)), the sum of the 
NOX emission limitations (in tons of NOX) on which 
each unit's exemption under Sec. 97.4(b) is based.
    (iii) If the number of NOX allowances in the allocation 
set-aside for the control period less the amount under paragraph 
(d)(5)(ii)(B) of this section is not less than the amount determined 
under paragraph (d)(5)(ii)(A) of this section, the Administrator will 
allocate the amount of the NOX allowances requested (as 
adjusted under paragraph (d)(5)(i) of this section) to the 
NOX Budget unit for which the allocation request was 
submitted.
    (iv) If the number of NOX allowances in the allocation 
set-aside for the control period less the amount under paragraph 
(d)(5)(ii)(B) of this section is less than the amount determined under 
paragraph (d)(5)(ii)(A) of this section, the Administrator will 
allocate, to the NOX Budget unit for which the allocation 
request was submitted, the amount of NOX allowances requested 
(as adjusted under paragraph (d)(5)(i) of this section) multiplied by 
the number of NOX allowances in the allocation set-aside for 
the control period less the amount determined under paragraph 
(d)(5)(ii)(B) of this section, divided by the amount determined under 
paragraph (d)(5)(ii)(A) of this section, and rounded to the nearest 
whole number of NOX allowances as appropriate.
    (e)(1) For a NOX Budget unit that is allocated 
NOX allowances under paragraph (d) of this section for a 
control period, the Administrator will deduct NOX allowances 
under Sec. 97.54(b), (e), or (f) to account for the actual heat input 
of the unit during the control period. The Administrator will calculate 
the number of NOX allowances to be deducted to account for 
the unit's actual heat input using the following formulas and rounding 
to the nearest whole number of NOX allowance as appropriate, 
provided that the number of NOX allowances to be deducted 
shall be zero if the number calculated is less than zero:

NOX allowances deducted for actual heat input for a unit 
under Sec. 97.4(a)(1) = Unit's NOX allowances allocated for 
control period-(Unit's actual control period heat input x the lesser of 
0.15 lb/mmBtu the unit's most stringent

[[Page 33]]

State or Federal emission limitation x 2,000 lb/ton); and NOX 
allowances deducted for actual heat input for a unit under Sec. 
97.4(a)(2) = Unit's NOX allowances allocated for control 
period-(Unit's actual control period heat input x the lesser of 0.17 lb/
mmBtu the unit's most stringent State or Federal emission limitation x 
2,000 lb/ton)

Where:

``Unit's NOX allowances allocated for control period'' is the 
          number of NOX allowances allocated to the unit for 
          the control period under paragraph (d) of this section; and
``Unit's actual control period heat input'' is the heat input (in mmBtu) 
          of the unit during the control period.

    (2) The Administrator will transfer any NOX allowances 
deducted under paragraph (e)(1) of this section to the allocation set-
aside for the control period for which they were allocated.
    (f) After making the deductions for compliance under Sec. 97.54(b), 
(e), or (f) for a control period, the Administrator will determine 
whether any NOX allowances remain in the allocation set-aside 
for the control period. The Administrator will allocate any such 
NOX allowances to the NOX Budget units in the 
State using the following formula and rounding to the nearest whole 
number of NOX allowances as appropriate:

Unit's share of NOX allowances remaining in allocation set-
aside = Total NOX allowances remaining in allocation set-
aside x (Unit's NOX allowance allocation / State's trading 
program budget excluding allocation set-aside)

Where:

``Total NOX allowances remaining in allocation set-aside'' is 
          the total number of NOX allowances remaining in the 
          allocation set-aside for the control period;
``Unit's NOX allowance allocation'' is the number of 
          NOX allowances allocated under paragraph (b) or (c) 
          of this section to the unit for the control period to which 
          the allocation set-aside applies; and
``State's trading program budget excluding allocation set-aside'' is the 
          State's trading program budget under Sec. 97.40 for the 
          control period to which the allocation set-aside applies 
          multiplied by 95 percent, rounded to the nearest whole number 
          of NOX allowances as appropriate.

    (g) If the Administrator determines that NOX allowances 
were allocated under paragraph (b), (c), or (d) of this section for a 
control period and the recipient of the allocation is not actually a 
NOX Budget unit under Sec. 97.4(a), the Administrator will 
notify the NOX authorized account representative and then 
will act in accordance with the following procedures:
    (1)(i) The Administrator will not record such NOX 
allowances for the control period in an account under Sec. 97.53;
    (ii) If the Administrator already recorded such NOX 
allowances for the control period in an account under Sec. 97.53 and if 
the Administrator makes such determination before making all deductions 
pursuant to Sec. 97.54 (except deductions pursuant to Sec. 
97.54(d)(2)) for the control period, then the Administrator will deduct 
from the account NOX allowances equal in number to and 
allocated for the same or a prior control period as the NOX 
allowances allocated to such recipient for the control period. The 
NOX authorized account representative shall ensure that the 
account contains the NOX allowances necessary for completion 
of such deduction. If account does not contain the necessary 
NOX allowances, the Administrator will deduct the required 
number of NOX allowances, regardless of the control period 
for which they were allocated, whenever NOX allowances are 
recorded in the account; or
    (iii) If the Administrator already recorded such NOX 
allowances for the control period in an account under Sec. 97.53 and if 
the Administrator makes such determination after making all deductions 
pursuant to Sec. 97.54 (except deductions pursuant to Sec. 
97.54(d)(2)) for the control period, then the Administrator will apply 
paragraph (g)(1)(ii) of this section to any subsequent control period 
for which NOX allowances were allocated to such recipient.
    (2) The Administrator will transfer the NOX allowances 
that are not recorded, or that are deducted, pursuant to paragraph 
(g)(1) of this section to an

allocation set-aside for the State in which such source is located.

Sec. 97.43  Compliance Supplement Pool.

    (a) For any NOX Budget unit that reduces its 
NOX emission rate in the 2001 through 2003 control period, 
the owners and operators may request early reduction credits in 
accordance with the following requirements:
    (1) Each NOX Budget unit for which the owners and 
operators intend to request, or request, any early reduction credits in 
accordance with paragraph (a)(4) of this section shall monitor and 
report NOX emissions in accordance with subpart H of this 
part starting in the 2000 control period and for each control period for 
which such early reduction credits are requested. The unit's percent 
monitor data availability shall not be less than 90 percent during the 
2000 control period, and the unit must be in full compliance with any 
applicable State or Federal NOX emission control requirements 
during 2000 through 2002.
    (2) NOX emission rate and heat input under paragraphs 
(a)(3) and (4) of this section shall be determined in accordance with 
subpart H of this part.
    (3) Each NOX Budget unit for which the owners and 
operators intend to request, or request, any early reduction credits 
under paragraph (a)(4) of this section shall reduce its NOX 
emission rate, for each control period for which early reduction credits 
are requested, to less than both 0.25 lb/mmBtu and 80 percent of the 
unit's NOX emission rate in the 2000 control period.
    (4) The NOX authorized account representative of a 
NOX Budget unit that meets the requirements of paragraphs (a) 
(1) and (3) of this section may submit to the Administrator a request 
for early reduction credits for the unit based on NOX 
emission rate reductions made by the unit in the control period for 2001 
through 2003.
    (i) In the early reduction credit request, the NOX 
authorized account may request early reduction credits for such control 
period in an amount equal to the unit's heat input for such control 
period multiplied by the difference between 0.25 lb/mmBtu and the unit's 
NOX emission rate for such control period, divided by 2000 
lb/ton, and rounded to the nearest whole number of tons.
    (ii) The early reduction credit request must be submitted, in a 
format specified by the Administrator, by February 1, 2004.
    (b) For any NOX Budget unit that is subject to the Ozone 
Transport Commission NOX Budget Program under title I of the 
Clean Air Act, the owners and operators may request early reduction 
credits in accordance with the following requirements:
    (1) The NOX authorized account representative of the unit 
may submit to the Administrator a request for early reduction credits in 
an amount equal to the amount of banked allowances under the Ozone 
Transport Commission NOX Budget Program that were allocated 
for the control period in 2001 through 2003 and are held by the unit, in 
accordance with the Ozone Transport Commission NOX Budget 
Program, as of the date of submission of the request. During the entire 
control period in 2001 through 2003 for which the allowances were 
allocated, the unit must have monitored and reported NOX 
emissions in accordance with part 75 (except for subpart H) of this 
chapter and the Guidance for Implementation of Emission Monitoring 
Requirements for the NOX Budget Program (January 28, 1997).
    (2) The early reduction credit request under paragraph (b)(1) must 
be submitted, in a format specified by the Administrator, by February 1, 
2004.
    (3) The NOX authorized account representative of the unit 
shall not submit a request for early reduction credits under paragraph 
(b)(1) of this section for banked allowances under the Ozone Transport 
Commission NOX Budget Program that were allocated for any 
control period during which the unit made NOX emission 
reductions for which he or she submits a request for early reduction 
credits under paragraph (a) of this section for the unit.
    (c) The Administrator will review each early reduction credit 
request submitted in accordance with paragraph (a) or (b) of this 
section and will allocate NOX allowances to NOX 
Budget

[[Page 35]]

units in a given State and covered by such request as follows:
    (1) Upon receipt of each early reduction credit request, the 
Administrator will make any necessary adjustments to the request to 
ensure that the amount of the early reduction credits requested meets 
the requirements of paragraph (a) or (b) of this section.
    (2) After February 1, 2004, the Administrator will make available to 
the public a statement of the total number of early reduction credits 
requested by NOX Budget units in the State.
    (3) If the State's compliance supplement pool set forth in appendix 
D to this subpart has a number of NOX allowances not less 
than the amount of early reduction credits in all early reduction credit 
requests under paragraph (a) or (b) of this section for 2001 through 
2003 (as adjusted under paragraph (c)(1) of this section) submitted by 
February 1, 2004, the Administrator will allocate to each NOX 
Budget unit covered by such requests one allowance for each early 
reduction credit requested (as adjusted under paragraph (c)(1) of this 
section).
    (4) If the State's compliance supplement pool set forth in appendix 
D to this subpart has a smaller number of NOX allowances than 
the amount of early reduction credits in all early reduction credit 
requests under paragraph (a) or (b) of this section for 2001 through 
2003 (as adjusted under paragraph (c)(1) of this section) submitted by 
February 1, 2004, the Administrator will allocate NOX 
allowances to each NOX Budget unit covered by such requests 
according to the following formula and rounding to the nearest whole 
number of NOX allowances as appropriate:

Unit's allocation for early reduction credits = Unit's adjusted early 
reduction credits x (State's compliance supplement pool / Total adjusted 
early reduction credits for all units)

Where:

``Unit's allocation for early reduction credits'' is the number of 
          NOX allowances allocated to the unit for early 
          reduction credits.
``Unit's adjusted early reduction credits'' is the amount of early 
          reduction credits requested for the unit for 2001 and 2002 in 
          early reduction credit requests under paragraph (a) or (b) of 
          this section, as adjusted under paragraph (c)(1) of this 
          section.
``State's compliance supplement pool'' is the number of NOX 
          allowances in the State's compliance supplement pool set forth 
          in appendix D to this subpart.
``Total adjusted early reduction credits for all units'' is the amount 
          of early reduction credits requested for all units for 2001 
          and 2002 in early reduction credit requests under paragraph 
          (a) or (b) of this section, as adjusted under paragraph (c)(1) 
          of this section.

    (5) By April 1, 2004, the Administrator will determine by order the 
allocations under paragraph (c)(3) or (4) of this section. The 
Administrator will make available to the public each determination of 
NOX allowance allocations and will provide an opportunity for 
submission of objections to the determination. Objections shall be 
limited to addressing whether the determination is in accordance with 
paragraph (c)(1), (3), or (4) of this section. Based on any such 
objections, the Administrator will adjust each determination to the 
extent necessary to ensure that it is in accordance with paragraph 
(c)(1), (3), or (4) of this section.
    (6) By May 1, 2004, the Administrator will record the allocations 
under paragraph (c)(3) or (4) of this section.
    (7) NOX allowances recorded under paragraph (c)(6) of 
this section may be deducted for compliance under Sec. 97.54 for the 
control period in 2004 or 2005. Notwithstanding Sec. 97.55(a), the 
Administrator will deduct as retired any NOX allowance that 
is recorded under paragraph (c)(6) of this section and that is not 
deducted for compliance under Sec. 97.54 for the control period in 2003 
or 2004.

carry out my duties and responsibilities under the NOX Budget 
Trading Program on behalf of such persons and that each such person

[[Page 53]]

general account. Each such submission shall include the following 
certification statement by the NOX authorized account 
representative or any alternate NOX authorizing account

penalty of law that I have personally examined, and am familiar with, 
the statements and information submitted in this document and all its 
attachments. Based on my inquiry of those individuals with primary 
responsibility for obtaining the information, I certify that the

penalties for submitting false statements and information or omitting 
required statements and information, including the possibility of fine 
or imprisonment.''

persons with ownership interest. (i) The NOX authorized 
account representative for a general account may be changed at any time 
upon receipt by the Administrator of a superseding complete application 
for a general account under paragraph (b)(1) of this section. 
Notwithstanding any such change, all representations, actions, 
inactions, and submissions by the previous NOX authorized 
account representative prior to the time and date when the Administrator 
receives the superseding application for a general account shall be 
binding on the new NOX authorized account representative and 
the persons with an ownership interest with respect to the 
NOX allowances in the general account.
    (ii) The alternate NOX authorized account representative 
for a general account may be changed at any time upon receipt by the 
Administrator of a superseding complete application for a general 
account under paragraph (b)(1) of this section. Notwithstanding any such 
change, all representations, actions, inactions, and submissions by the 
previous alternate NOX authorized account representative 
prior to the time and date when the Administrator receives the 
superseding application for a general account shall be binding on the 
new alternate NOX authorized account representative and the 
persons with an ownership interest with respect to the NOX 
allowances in the general account.
    (iii)(A) In the event a new person having an ownership interest with 
respect to NOX allowances in the general account is not 
included in the list of such persons in the account certificate of 
representation, such new person shall be deemed to be subject to and 
bound by the account certificate of representation, the representation, 
actions, inactions, and submissions of the NOX authorized 
account representative and any alternate NOX authorized 
account representative of the source or unit, and the decisions, orders, 
actions, and inactions of the Administrator, as if the new person were 
included in such list.
    (B) Within 30 days following any change in the persons having an 
ownership interest with respect to NOX allowances in the 
general account, including the addition of persons, the NOX 
authorized account representative or any alternate NOX 
authorized account representative shall submit a revision to the 
application for a general account amending the list of persons having an 
ownership interest with respect to the NOX allowances in the 
general account to include the change.
    (4) Objections concerning NOX authorized account 
representative. (i) Once a complete application for a general account 
under paragraph (b)(1) of this section has been submitted and received, 
the Administrator will rely on the application unless and until a 
superseding complete application for a general account under paragraph 
(b)(1) of this section is received by the Administrator.

[[Page 54]]

    (ii) Except as provided in paragraph (b)(3)(i) or (ii) of this 
section, no objection or other communication submitted to the 
Administrator concerning the authorization, or any representation, 
action, inaction, or submission of the NOX authorized account 
representative or any alternative NOX authorized account 
representative for a general account shall affect any representation, 
action, inaction, or submission of the NOX authorized account 
representative or any alternative NOX authorized account 
representative or the finality of any decision or order by the 
Administrator under the NOX Budget Trading Program.
    (iii) The Administrator will not adjudicate any private legal

    (a) NOX allowance transfer deadline. The NOX 
allowances are available to be deducted for compliance with a unit's 
NOX Budget emissions limitation for a control period in a 
given year only if the NOX allowances:
    (1) Were allocated for a control period in a prior year or the same 
year; and
    (2) Are held in the unit's compliance account, or the overdraft 
account of the source where the unit is located, as of the 
NOX allowance transfer deadline for that control period or 
are transferred into the compliance account or overdraft account by a 
NOX allowance transfer correctly submitted for recordation 
under Sec. 97.60 by the NOX allowance transfer deadline for 
that control period.
    (b) Deductions for compliance. (1) Following the recordation, in 
accordance with Sec. 97.61, of NOX allowance transfers 
submitted for recordation in the unit's compliance account or the 
overdraft account of the source where the unit is located by the 
NOX allowance transfer deadline for a control period, the 
Administrator will deduct NOX allowances available under 
paragraph (a) of this section to cover the unit's NOX 
emissions (as determined in accordance with subpart H of this part), or 
to account for actual heat input under Sec. 97.42(e), for the control 
period:
    (i) From the compliance account; and
    (ii) Only if no more NOX allowances available under 
paragraph (a) of this section remain in the compliance account, from the 
overdraft account. In deducting allowances for units at the source from 
the overdraft account, the Administrator will begin with the unit having 
the compliance account with the lowest account number and end with the 
unit having the compliance account with the highest account number (with 
account numbers sorted beginning with the left-most character and ending 
with the right-most character and the letter characters assigned values 
in alphabetical order and less than all numeric characters).
    (2) The Administrator will deduct NOX allowances first 
under paragraph (b)(1)(i) of this section and then under paragraph 
(b)(1)(ii) of this section:
    (i) Until the number of NOX allowances deducted for the 
control period equals the number of tons of NOX emissions, 
determined in accordance with subpart H of this part, from the unit for 
the control period for which compliance is being determined, plus the 
number of NOX allowances required for deduction to account 
for actual heat input under Sec. 97.42(e) for the control period; or
    (ii) Until no more NOX allowances available under 
paragraph (a) of this section remain in the respective account.
    (c)(1) Identification of NOX allowances by serial number. The 
NOX authorized account representative for each compliance 
account may identify by serial number the NOX allowances to 
be deducted from the unit's compliance account under paragraph (b), (d), 
(e), or (f) of this section. Such identification shall be made in the 
compliance certification report submitted in accordance with Sec. 
97.30.
    (2) First-in, first-out. The Administrator will deduct 
NOX allowances for a control period from the compliance 
account, in the absence of an identification or in the case of a partial 
identification of NOX allowances by serial number under 
paragraph (c)(1) of this section, or the overdraft account on a

[[Page 56]]

first-in, first-out (FIFO) accounting basis in the following order:
    (i) Those NOX allowances that were allocated for the 
control period to the unit under subpart E or I of this part;
    (ii) Those NOX allowances that were allocated for the 
control period to any unit and transferred and recorded in the account 
pursuant to subpart G of this part, in order of their date of 
recordation;
    (iii) Those NOX allowances that were allocated for a 
prior control period to the unit under subpart E or I of this part; and
    (iv) Those NOX allowances that were allocated for a prior 
control period to any unit and transferred and recorded in the account 
pursuant to subpart G of this part, in order of their date of 
recordation.
    (d) Deductions for excess emissions. (1) After making the deductions 
for compliance under paragraph (b) of this section, the Administrator 
will deduct from the unit's compliance account or the overdraft account 
of the source where the unit is located a number of NOX 
allowances, allocated for a control period after the control period in 
which the unit has excess emissions, equal to three times the number of 
the unit's excess emissions.
    (2) If the compliance account or overdraft account does not contain 
sufficient NOX allowances, the Administrator will deduct the 
required number of NOX allowances, regardless of the control 
period for which they were allocated, whenever NOX allowances 
are recorded in either account.
    (3) Any allowance deduction required under paragraph (d) of this 
section shall not affect the liability of the owners and operators of 
the NOX Budget unit for any fine, penalty, or assessment, or 
their obligation to comply with any other remedy, for the same 
violation, as ordered under the Clean Air Act or applicable State law. 
The following guidelines will be followed in assessing fines, penalties 
or other obligations:
    (i) For purposes of determining the number of days of violation, if 
a NOX Budget unit has excess emissions for a control period, 
each day in the control period (153 days) constitutes a day in violation 
unless the owners and operators of the unit demonstrate that a lesser 
number of days should be considered.
    (ii) Each ton of excess emissions is a separate violation.
    (e) Deductions for units sharing a common stack. In the case of 
units sharing a common stack and having emissions that are not 
separately monitored or apportioned in accordance with subpart H of this 
part:
    (1) The NOX authorized account representative of the 
units may identify the percentage of NOX allowances to be 
deducted from each such unit's compliance account to cover the unit's 
share of NOX emissions from the common stack for a control 
period. Such identification shall be made in the compliance 
certification report submitted in accordance with Sec. 97.30.
    (2) Notwithstanding paragraph (b)(2)(i) of this section, the 
Administrator will deduct NOX allowances for each such unit 
until the number of NOX allowances deducted equals the unit's 
identified percentage under paragraph (e)(1) of this section or, if no 
percentage is identified, an equal percentage for each unit multiplied 
by the number of tons of NOX emissions, as determined in 
accordance with subpart H of this part, from the common stack for the 
control period for which compliance is being determined. In addition to 
the deductions under the first sentence of this paragraph (e)(1), the 
Administrator will deduct NOX allowances for each such unit 
until the number of NOX allowances deducted equals the number 
of NOX allowances required to account for actual heat input 
under Sec. 97.42(e) for the unit for the control period.
    (f) Deduction of banked allowances. Each year starting in 2006, 
after the Administrator has completed the designation of banked 
NOX allowances under Sec. 97.55(b) and before May 1 of the 
year, the Administrator will determine the extent to which banked 
NOX allowances otherwise available under paragraph (a) of 
this section are available for compliance in the control period for the 
current year, as follows. For each State NOX Budget Trading 
Program that is established, and approved and administered by the 
Administrator pursuant to Sec. 51.121 of this chapter, the

[[Page 57]]

terms ``compliance account'' or ``compliance accounts'', ``overdraft 
account'' or ``overdraft accounts'', ``general account'' or ``general 
accounts'', ``States'', and ``trading program budgets under Sec. 
97.40'' in paragraphs (f)(1) through (f)(3) of this section shall be 
read to include respectively: A compliance account or compliance 
accounts established under such State NOX Budget Trading 
Program; an overdraft account or overdraft accounts established under 
such State NOX Budget Trading Program; a general account or 
general accounts established under such State NOX Budget 
Trading Program; the State or portion of a State covered by such State 
NOX Budget Trading Program; and the trading program budget of 
the State or portion of a State covered by such State NOX 
Budget Trading Program.
    (1) The Administrator will determine the total number of banked 
NOX allowances held in compliance accounts, overdraft 
accounts, or general accounts.
    (2) If the total number of banked NOX allowances 
determined, under paragraph (f)(1) of this section, to be held in 
compliance accounts, overdraft accounts, or general accounts is less 
than or equal to 10 percent of the sum of the trading program budgets 
under Sec. 97.40 for all States for the control period, any banked 
NOX allowance may be deducted for compliance in accordance 
with paragraphs (a) through (e) of this section.
    (3) If the total number of banked NOX allowances 
determined, under paragraph (f)(1) of this section, to be held in 
compliance accounts, overdraft accounts, or general accounts exceeds 10 
percent of the sum of the trading program budgets under Sec. 97.40 for 
all States for the control period, any banked allowance may be deducted 
for compliance in accordance with paragraphs (a) through (e) of this 
section, except as follows:
    (i) The Administrator will determine the following ratio: 0.10 
multiplied by the sum of the trading program budgets under Sec. 97.40 
for all States for the control period and divided by the total number of 
banked NOX allowances determined, under paragraph (f)(1) of 
this section, to be held in compliance accounts, overdraft accounts, or 
general accounts.
    (ii) The Administrator will multiply the number of banked 
NOX allowances in each compliance account or overdraft 
account by the ratio determined under paragraph (f)(3)(i) of this 
section. The resulting product is the number of banked NOX 
allowances in the account that may be deducted for compliance in 
accordance with paragraphs (a) through (e) of this section. Any banked 
NOX allowances in excess of the resulting product may be 
deducted for compliance in accordance with paragraphs (a) through (e) of 
this section, except that, if such NOX allowances are used to 
make a deduction under paragraph (b) or (e) of this section, two (rather 
than one) such NOX allowances shall authorize up to one ton 
of NOX emissions during the control period and must be 
deducted for each deduction of one NOX allowance required 
under paragraph (b) or (e) of this section.
    (g) Recordation of deductions. The Administrator will record in the 
appropriate compliance account or overdraft account all deductions from 
such an account pursuant to paragraph (b), (d), (e), or (f) of this 
section.

FR 21646, Apr. 21, 2004]



Sec. 97.55  Banking.

    NOX allowances may be banked for future use or transfer 
in a compliance account, an overdraft account, or a general account, as 
follows:
    (a) Any NOX allowance that is held in a compliance 
account, an overdraft account, or a general account will remain in such 
account unless and until the NOX allowance is deducted or 
transferred under Sec. 97.31, Sec. 97.54, Sec. 97.56, or subpart G or 
I of this part.
    (b) The Administrator will designate, as a ``banked'' NOX 
allowance, any NOX allowance that remains in a compliance 
account, an overdraft account, or a general account after the 
Administrator has made all deductions for a given control period from 
the compliance account or overdraft account pursuant to Sec. 97.54 
(except deductions pursuant to Sec. 97.54(d)(2)) and that was allocated 
for that control period or a control period in a prior year.

her own motion, correct any error in any NOX Allowance 
Tracking System account. Within 10 business days of making such 
correction, the Administrator will notify the NOX authorized 
account representative for the account.



Sec. 97.57  Closing of general accounts.

    (a) The NOX authorized account representative of a 
general account may instruct the Administrator to close the account by 
submitting a statement requesting deletion of the account from the 
NOX Allowance Tracking System and by correctly submitting for 
recordation under Sec. 97.60 an allowance transfer of all 
NOX allowances in the account to one or more other 
NOX Allowance Tracking System accounts.
    (b) If a general account shows no activity for a period of a year or 
more and does not contain any NOX allowances, the 
Administrator may notify the NOX authorized account 
representative for the account that the account will be closed and 
deleted from the NOX Allowance Tracking System following 20 
business days after the notice is sent. The account will be closed after 
the 20-day period unless before the end of the 20-day period the 
Administrator receives a correctly submitted transfer of NOX 
allowances into the account under Sec. 97.60 or a statement submitted 
by the NOX authorized account representative demonstrating to 
the satisfaction of the Administrator good cause as to why the account 
should not be closed.

    (2) Requirements for recertification. Whenever the owner or operator 
makes a replacement, modification, or change in a certified emission 
monitoring system that may significantly affect the ability of the 
system to accurately measure or record NOX mass emissions or 
heat input rate or to meet the requirements of Sec. 75.21 of this 
chapter or appendix B to part 75 of this chapter, the owner or operator 
shall recertify the emission monitoring system in accordance with Sec. 
75.20(b) of this chapter. Furthermore, whenever the owner or operator 
makes a replacement, modification, or change to the flue gas handling 
system or the unit's operation that may significantly change the stack 
flow or concentration profile, the owner or operator shall recertify the 
continuous emissions monitoring system in accordance with Sec. 75.20(b) 
of this chapter. Examples of changes that require recertification 
include: replacement of the analyzer, complete replacement of an 
existing continuous emission monitoring system, or change in location or 
orientation of the sampling probe or site.
    (3) Certification approval process for initial certification and 
recertification--(i) Notification of certification. The NOX 
authorized account representative shall submit to the Administrator, the 
appropriate EPA Regional Office and the permitting authority written 
notice of the dates of certification in accordance with Sec. 97.73.
    (ii) Certification application. The NOX authorized 
account representative shall submit to the Administrator, the 
appropriate EPA Regional Office and the permitting authority a 
certification application for each emission monitoring system required 
under subpart H of part 75 of this chapter. A complete certification 
application shall include the information specified in subpart H of part 
75 of this chapter.
    (iii) Except for units using the low mass emission excepted 
methodology under Sec. 75.19 of this chapter, the provisional 
certification date for a monitor shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitor may 
be used under the NOX Budget Trading Program for a period not 
to exceed 120 days after receipt by the Administrator of the complete 
certification application for the monitoring system under paragraph 
(b)(3)(ii) of this section. Data measured and recorded by the 
provisionally certified monitoring system, in accordance with the 
requirements of part 75 of this chapter, will be considered valid 
quality-assured data (retroactive to the date and time of provisional 
certification), provided that the Administrator does not invalidate the 
provisional certification by issuing a notice of disapproval within 120 
days of receipt of the complete certification application by the 
Administrator.
    (iv) Certification application formal approval process. The 
Administrator will issue a written notice of approval or disapproval of 
the certification application to the owner or operator within 120 days 
of receipt of the complete certification application under paragraph 
(b)(3)(ii) of this section. In the event the Administrator does not 
issue such a notice within such 120-day period, each monitoring system 
that meets the applicable performance requirements of part 75 of this 
chapter and is included in the certification application will be deemed 
certified for use under the NOX Budget Trading Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. A certification application will 
be considered complete when all of the applicable information required 
to be submitted under paragraph (b)(3)(ii) of this section has been 
received by the Administrator. If the certification application is not 
complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the NOX 
authorized account representative must submit the additional information 
required to complete the certification application.

[[Page 63]]

If the NOX authorized account representative does not comply 
with the notice of incompleteness by the specified date, then the 
Administrator may issue a notice of disapproval under paragraph 
(b)(3)(iv)(C) of this section. The 120-day review period shall not begin 
prior to receipt of a complete certification application.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system or component thereof does not meet the performance 
requirements of this part, or if the certification application is 
incomplete and the requirement for disapproval under paragraph 
(b)(3)(iv)(B) of this section has been met, then the Administrator will 
issue a written notice of disapproval of the certification application. 
Upon issuance of such notice of disapproval, the provisional 
certification is invalidated by the Administrator and the data measured 
and recorded by each uncertified monitoring system shall not be 
considered valid quality-assured data beginning with the date and hour 
of provisional certification (as defined under Sec. 75.20(a)(3) of this 
chapter). The owner or operator shall follow the procedures for loss of 
certification in paragraph (b)(3)(v) of this section for each monitoring 
system that is disapproved for initial certification.
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.72(b).
    (v) Procedures for loss of certification. If the Administrator 
issues a notice of disapproval of a certification application under 
paragraph (b)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (b)(3)(iv)(D) of this section, 
then:
    (A) The owner or operator shall substitute the following values, for 
each hour of unit operation during the period of invalid data specified 
under Sec. 75.20(a)(4)(iii), Sec. 75.20(b)(5), Sec. 75.20(h)(4), or 
Sec. 75.21(e) and continuing until the date and hour specified under 
Sec. 75.20(a)(5)(i) of this chapter:
    (1) For units that the owner or operator intends to monitor or 
monitors for NOX emission rate and heat input rate or intends 
to determine or determines NOX mass emissions using the low 
mass emission excepted methodology under Sec. 75.19 of this chapter, 
the maximum potential NOX emission rate and the maximum 
potential hourly heat input of the unit; and
    (2) For units that the owner or operator intends to monitor or 
monitors for NOX mass emissions using a NOX 
pollutant concentration monitor and a flow monitor, the maximum 
potential concentration of NOX and the maximum potential flow 
rate of the unit under section 2 of appendix A of part 75 of this 
chapter.
    (B) The NOX authorized account representative shall 
submit a notification of certification retest dates and a new 
certification application in accordance with paragraphs (b)(3)(i) and 
(ii) of this section.
    (C) The owner or operator shall repeat all certification tests or 
other requirements that were failed by the monitoring system, as 
indicated in the Administrator's notice of disapproval, no later than 30 
unit operating days after the date of issuance of the notice of 
disapproval.
    (c) Initial certification and recertification procedures for low 
mass emission units using the excepted methodologies under Sec. 75.19 
of this chapter. The owner or operator of a gas-fired or oil-fired unit

this chapter and not subject to an Acid Rain emissions limitation shall 
meet the applicable general operating requirements of Sec. 75.10 of 
this chapter and the applicable requirements of Sec. 75.19 of this 
chapter. The owner or operator of such a unit shall also meet the 
applicable certification and recertification procedures of paragraph (b) 
of this section, except that the excepted methodology shall be deemed 
provisionally certified for use under the NOX Budget Trading 
Program as of the date on which a complete certification application is 
received by the Administrator. The methodology shall be considered to be 
certified either upon receipt of a written notice of approval from the 
Administrator or, if such notice is not provided, at the end of the 
Administrator's 120 day review period. However, a provisionally 
certified or certified low mass emissions excepted methodology shall not 
be used to report data under

[[Page 64]]

the NOX Budget Trading Program prior to the applicable 
commencement date specified in Sec. 75.19(a)(1)(ii) of this chapter.
    (d) Certification/recertification procedures for alternative 
monitoring systems. The NOX authorized account representative 
of each unit not subject to an Acid Rain emissions limitation for which 
the owner or operator intends to use an alternative monitoring system 
approved by the Administrator under subpart E of part 75 of this chapter 
shall comply with the applicable certification procedures of paragraph 
(b) of this section before using the system under the NOX 
Budget Trading Program. The NOX authorized account

Sec. 97.72  Out of control periods.

    (a) Whenever any emission monitoring system fails to meet the 
quality assurance or data validation requirements of part 75 of this 
chapter, data shall be substituted using the applicable procedures in 
subpart D, subpart H, appendix D, or appendix E of part 75 of this 
chapter.
    (b) Audit decertification. Whenever both an audit of an emission 
monitoring system and a review of the initial certification or 
recertification application reveal that any system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.71 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such system. For the purposes 
of this paragraph, an audit shall be either a field audit or an audit of 
any information submitted to the permitting authority or the 
Administrator. By issuing the notice of disapproval, the Administrator 
revokes prospectively the certification status of the system. The data 
measured and recorded by the system shall not be considered valid 
quality-assured data from the date of issuance of the notification of 
the revoked certification status until the date and time that the owner 
or operator completes subsequently approved initial certification or 
recertification tests for the system. The owner or operator shall follow 
the initial certification or recertification procedures in Sec. 97.71 
for each disapproved system.

previously designated for the unit.
    (b) Duty to reapply. Unless the NOX Budget opt-in permit 
is terminated or revised under Sec. 97.86(e) or Sec. 97.87(b)(1)(i), 
the NOX authorized account representative of a NOX 
Budget opt-in unit shall submit to the Administrator and permitting 
authority a complete NOX Budget permit application under 
Sec. 97.22 to renew the NOX Budget opt-in permit in 
accordance with Sec. 97.21(c) and, if applicable, an updated monitoring 
plan in accordance with subpart H of this part.



Sec. 97.84  Opt-in process.

    The permitting authority will issue or deny an initial 
NOX Budget opt-in permit for a unit for which an application 
for a NOX Budget opt-in permit under Sec. 97.83 is 
submitted, in accordance with Sec. 97.20 and the following:
    (a) Interim review of monitoring plan. The Administrator will 
determine, on an interim basis, the sufficiency of the monitoring plan 
accompanying the initial application for a NOX Budget opt-in 
permit under Sec. 97.83. A monitoring plan is sufficient, for purposes 
of interim review, if the plan appears to contain information 
demonstrating that the NOX emissions rate and heat input rate 
of the unit are monitored and reported in accordance with subpart H of 
this part. A determination of sufficiency shall not be construed as 
acceptance or approval of the unit's monitoring plan.
    (b) If the Administrator determines that the unit's monitoring plan 
is sufficient under paragraph (a) of this section and after completion 
of monitoring system certification under subpart H of this part, the 
NOX emissions rate and the heat input of the unit shall be 
monitored and reported in accordance with subpart H of this part for one 
full control period during which percent monitor data availability is 
not less than 90 percent and during which the unit is in full compliance 
with any applicable State or Federal emissions or emissions-related 
requirements. Solely for purposes of applying the requirements in the 
prior sentence, the unit shall be treated as a ``NOX Budget 
unit'' prior to issuance of a NOX Budget opt-in permit 
covering the unit.
    (c) Based on the information monitored and reported under paragraph 
(b) of this section, the Administrator will calculate the unit's 
baseline heat input, which will equal the unit's total heat input (in 
mmBtu) for the control period, and the unit's baseline NOX 
emissions rate, which will equal the unit's total NOX mass 
emissions (in lb) for the control period divided by the unit's baseline 
heat input.
    (d) Issuance of draft NOX Budget opt-in permit for public 
comment. The permitting authority will issue a draft NOX 
Budget opt-in permit for public comment in accordance with Sec. 97.20.
    (e) Not withstanding paragraphs (a) through (d) of this section, if 
at any time before issuance of a draft NOX Budget opt-in 
permit for public comment for the unit, the Administrator or the 
permitting authority determines that the unit does not qualify as a 
NOX Budget opt-in unit under Sec. 97.80, the permitting 
authority will issue a draft denial of a NOX Budget opt-in 
permit for public comment for the unit in accordance with Sec. 97.20.

a NOX Budget opt-in permit under Sec. 97.83 for the unit 
prior to the date that is 4 years after the date on which the terminated 
NOX Budget opt-in permit became effective.



Sec. 97.87  Change in regulatory status.

    (a) Notification. When a NOX Budget opt-in unit becomes a 
NOX Budget unit under Sec. 97.4(a), the NOX 
authorized account representative shall notify in writing the permitting 
authority and the Administrator of such change in the NOX 
Budget opt-in unit's regulatory status, within 30 days of such change.
    (b) Permitting authority's and Administrator's action. (1)(i) When 
the NOX Budget opt-in unit becomes a NOX Budget 
unit under Sec. 97.4(a), the permitting authority will revise the 
NOX Budget opt-in unit's NOX Budget opt-in permit 
to meet the requirements of a NOX Budget permit under Sec. 
97.23 as of an effective date that is the date on which such 
NOX Budget opt-in unit becomes a NOX Budget unit 
under Sec. 97.4(a).
    (ii)(A) The Administrator will deduct from the compliance account 
for the NOX Budget unit under paragraph (b)(1)(i) of this 
section, or the overdraft account of the NOX Budget source 
where the unit is located, NOX allowances equal in number to 
and allocated for the same or a prior control period as:
    (1) Any NOX allowances allocated to the NOX 
Budget unit (as a NOX Budget opt-in unit) under Sec. 97.88 
for any control period after the last control period during which the 
unit's NOX Budget opt-in permit was effective; and
    (2) If the effective date of the NOX Budget permit 
revision under paragraph (b)(1)(i) of this section is during a control 
period, the NOX allowances allocated to the NOX 
Budget unit (as a NOX Budget opt-in unit) under Sec. 97.88 
for the control period multiplied by the number of days in the control 
period starting with the effective date of the permit revision under 
paragraph (b)(1)(i) of this section, divided by the total number of days 
in the control period, and rounded to the nearest whole number of 
NOX allowances as appropriate.
    (B) The NOX authorized account representative shall 
ensure that the compliance account of the NOX Budget unit 
under paragraph (b)(1)(i) of this section, or the overdraft account of 
the NOX Budget source where the unit is located, contains the 
NOX allowances necessary for completion of the deduction 
under paragraph (b)(1)(ii)(A) of this section. If the compliance account 
or overdraft account does not contain

[[Page 70]]

the necessary NOX allowances, the Administrator will deduct 
the required number of NOX allowances, regardless of the 
control period for which they were allocated, whenever NOX 
allowances are recorded in either account.
    (iii)(A) For every control period during which the NOX 
Budget permit revised under paragraph (b)(1)(i) of this section is in 
effect, the NOX Budget unit under paragraph (b)(1)(i) of this 
section will be treated, solely for purposes of NOX allowance 
allocations under Sec. 97.42, as a unit that commenced operation on the 
effective date of the NOX Budget permit revision under 
paragraph (b)(1)(i) of this section and will be allocated NOX 
allowances under Sec. 97.42. The unit's deadline under Sec. 97.84(b) 
for meeting monitoring requirements in accordance with subpart H of this 
part shall not be changed by the change in the unit's regulatory status 
or by the revision of the NOX Budget permit under paragraph 
(b)(1)(i) of this section.
    (B) Notwithstanding paragraph (b)(1)(iii)(A) of this section, if the 
effective date of the NOX Budget permit revision under 
paragraph (b)(1)(i) of this section is during a control period, the 
following number of NOX allowances will be allocated to the 
NOX Budget unit under paragraph (b)(1)(i) of this section 
under Sec. 97.42 for the control period: the number of NOX 
allowances otherwise allocated to the NOX Budget unit under 
Sec. 97.42 for the control period multiplied by the number of days in 
the control period starting with the effective date of the permit 
revision under paragraph (b)(1)(i) of this section, divided by the total 
number of days in the control period, and rounded to the nearest whole 
number of NOX allowances as appropriate.
    (2)(i) When the NOX authorized account representative of 
a NOX Budget opt-in unit does not renew its NOX 
Budget opt-in permit under Sec. 97.83(b), the Administrator will deduct 
from the NOX Budget opt-in unit's compliance account, or the 
overdraft account of the NOX Budget source where the 
NOX Budget opt-in unit is located, NOX allowances 
equal in number to and allocated for the same or a prior control period 
as any NOX allowances allocated to the NOX Budget 
opt-in unit under Sec. 97.88 for any control period after the last 
control period for which the NOX Budget opt-in permit is 
effective. The NOX authorized account representative shall 
ensure that the NOX Budget opt-in unit's compliance account 
or the overdraft account of the NOX Budget source where the 
NOX Budget opt-in unit is located contains the NOX 
allowances necessary for completion of such deduction. If the compliance 
account or overdraft account does not contain the necessary 
NOX allowances, the Administrator will deduct the required 
number of NOX allowances, regardless of the control period 
for which they were allocated, whenever NOX allowances are 
recorded in either account.
    (ii) After the deduction under paragraph (b)(2)(i) of this section 
is completed, the Administrator will close the NOX Budget 
opt-in unit's compliance account. If any NOX allowances 
remain in the compliance account after completion of such deduction and 
any deduction under Sec. 97.54, the Administrator will close the 
NOX Budget opt-in unit's compliance account and transfer any 
remaining allowances to a general account specified by the owners and 
operators of the NOX Budget opt-in unit.

part.
    (5) A CAIR NOX allowance is a limited authorization to 
emit one ton of nitrogen oxides in accordance with the CAIR 
NOX Annual Trading Program. No provision of the CAIR 
NOX Annual Trading Program, the CAIR permit application, the

shall be construed to limit the authority of the United States to 
terminate or limit such authorization.

compliance account is incorporated automatically in any CAIR permit of 
the source.
    (d) Excess emissions requirements. If a CAIR NOX source 
emits nitrogen oxides during any control period in excess of the CAIR 
NOX emissions limitation, then:

NOX unit at the source shall surrender the CAIR 
NOX allowances required for deduction under Sec. 
97.154(d)(1) and pay any fine, penalty, or assessment or comply with any 
other remedy imposed, for the same violations, under the Clean Air Act 
or applicable State law; and
    (2) Each ton of such excess emissions and each day of such control 
period shall constitute a separate violation of this subpart, the Clean 
Air Act, and applicable State law.
    (e) Recordkeeping and reporting requirements. (1) Unless otherwise 
provided, the owners and operators of the CAIR NOX source and 
each CAIR NOX unit at the source shall keep on site at the 
source each of the following documents for a period of 5 years from the 
date the document is created. This period may be extended for cause, at 
any time before the end of 5 years, in writing by the permitting 
authority or the Administrator.
    (i) The certificate of representation under Sec. 97.113 for the 
CAIR designated representative for the source and each CAIR 
NOX unit at the source and all documents that demonstrate the 
truth of the statements in the certificate of representation; provided 
that the certificate and documents shall be retained on site at the 
source beyond such 5-year period until such documents are superseded 
because of the submission of a new certificate of representation under 
Sec. 97.113 changing the CAIR designated representative.
    (ii) All emissions monitoring information, in accordance with 
subpart HH of this part, provided that to the extent that subpart HH of

submissions and all records made or required under the CAIR 
NOX Annual Trading Program.
    (iv) Copies of all documents used to complete a CAIR permit 
application and any other submission under the CAIR NOX 
Annual Trading Program or to demonstrate compliance with the

    (f) Liability. (1) Each CAIR NOX source and each CAIR 
NOX unit shall meet the requirements of the CAIR 
NOX Annual Trading Program.
    (2) Any provision of the CAIR NOX Annual Trading Program 
that applies to a CAIR NOX source or the CAIR designated 
representative of a CAIR NOX source shall also apply to the 
owners and operators of such source and of the CAIR NOX units 
at the source.
    (3) Any provision of the CAIR NOX Annual Trading Program 
that applies to a CAIR NOX unit or the CAIR designated 
representative of a CAIR NOX unit shall also apply to the 
owners and operators of such unit.
    (g) Effect on other authorities. No provision of the CAIR 
NOX Annual Trading Program, a CAIR permit application, a CAIR 
permit, or an exemption under Sec. 97.105 shall be construed as 
exempting or excluding the owners and operators, and the CAIR designated 
representative, of a CAIR NOX source or CAIR NOX 
unit from compliance with any other provision of the applicable, 
approved State implementation plan, a federally enforceable permit, or 
the Clean Air Act.



Sec. 97.107  Computation of time.

CAIR NOX Annual Trading Program, to begin on the occurrence 
of an act or event shall begin on the day the act or event occurs.

under Sec. 97.113. Notwithstanding any such change, all 
representations, actions, inactions, and submissions by the previous 
CAIR designated representative before the time and date when the 
Administrator receives the superseding certificate of representation 
shall be binding on the new CAIR designated representative and the 
owners and operators of the CAIR NOX source and the CAIR

allocations, in accordance with Sec. 97.142(a),(c), and (d), for the 
control period in the year of the applicable deadline for determination 
under this paragraph.
    (d) The Administrator will make available to the public each 
determination of CAIR NOX allowances under paragraph (a), 
(b), or (c) of this section and will provide an opportunity for 
submission of objections to the determination. Objections shall be 
limited to addressing whether the determination is in accordance with 
Sec. 97.142. Based on any such objections, the Administrator will 
adjust each determination to the extent necessary to ensure that it is 
in accordance with Sec. 97.142.



Sec. 97.142  CAIR NOX allowance allocations.

    (a)(1) The baseline heat input (in mmBtu) used with respect to CAIR 
NOX allowance allocations under paragraph (b) of this section 
for each CAIR NOX unit will be:
    (i) For units commencing operation before January 1, 2001 the 
average of the 3 highest amounts of the unit's adjusted control period 
heat input for 2000 through 2004, with the adjusted control period heat 
input for each year calculated as follows:
    (A) If the unit is coal-fired during the year, the unit's control 
period heat input for such year is multiplied by 100 percent;
    (B) If the unit is oil-fired during the year, the unit's control 
period heat input for such year is multiplied by 60 percent; and
    (C) If the unit is not subject to paragraph (a)(1)(i)(A) or (B) of 
this section, the unit's control period heat input for such year is 
multiplied by 40 percent.

[[Page 90]]

    (ii) For units commencing operation on or after January 1, 2001 and 
operating each calendar year during a period of 5 or more consecutive 
calendar years, the average of the 3 highest amounts of the unit's total 
converted control period heat input over the first such 5 years.
    (2)(i) A unit's control period heat input, and a unit's status as 
coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) 
of this section, and a unit's total tons of NOX emissions 
during a calendar year under paragraph (c)(3) of this section, will be 
determined in accordance with part 75 of this chapter, to the extent the 
unit was otherwise subject to the requirements of part 75 of this 
chapter for the year, or will be based on the best available data 
reported to the Administrator for the unit (in a format prescribed by 
the Administrator), to the extent the unit was not otherwise subject to 
the requirements of part 75 of this chapter for the year.
    (ii) A unit's converted control period heat input for a calendar 
year specified under paragraph (a)(1)(ii) of this section equals:
    (A) Except as provided in paragraph (a)(2)(ii)(B) or (C) of this 
section, the control period gross electrical output of the generator or 
generators served by the unit multiplied by 7,900 Btu/kWh, if the unit 
is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal-
fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that if 
a generator is served by 2 or more units, then the gross electrical 
output of the generator will be attributed to each unit in proportion to 
the unit's share of the total control period heat input of such units 
for the year;
    (B) For a unit that is a boiler and has equipment used to produce 
electricity and useful thermal energy for industrial, commercial, 
heating, or cooling purposes through the sequential use of energy, the 
total heat energy (in Btu) of the steam produced by the boiler during 
the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or
    (C) For a unit that is a combustion turbine and has equipment used 
to produce electricity and useful thermal energy for industrial, 
commercial, heating, or cooling purposes through the sequential use of 
energy, the control period gross electrical output of the enclosed 
device comprising the compressor, combustor, and turbine multiplied by 
3,413 Btu/kWh, plus the total heat energy (in Btu) of the steam produced 
by any associated heat recovery steam generator during the control 
period divided by 0.8, and with the sum divided by 1,000,000 Btu/mmBtu.
    (iii) Gross electrical output and total heat energy under paragraph 
(a)(2)(ii) of this section will be determined based on the best 
available data reported to the Administrator for the unit (in a format 
prescribed by the Administrator).
    (3) The Administrator will determine what data are the best 
available data under paragraph (a)(2) of this section by weighing the 
likelihood that data are accurate and reliable and giving greater weight 
to data submitted to a governmental entity in compliance with legal 
requirements or substantiated by an independent entity.
    (b)(1) For each control period in 2009 and thereafter, the 
Administrator will allocate to all CAIR NOX units in a State 
that have a baseline heat input (as determined under paragraph (a) of 
this section) a total amount of CAIR NOX allowances equal to 
95 percent for a control period during 2009 through 2014, and 97 percent 
for a control period during 2015 and thereafter, of the tons of 
NOX emissions in the applicable State trading budget under 
Sec. 97.140 (except as provided in paragraphs (d) and (e) of this 
section).
    (2) The Administrator will allocate CAIR NOX allowances 
to each CAIR NOX unit under paragraph (b)(1) of this section 
in an amount determined by multiplying the total amount of CAIR 
NOX allowances allocated under paragraph (b)(1) of this 
section by the ratio of the baseline heat input of such CAIR 
NOX unit to the total amount of baseline heat input of all 
such CAIR NOX units in the State and rounding to the nearest 
whole allowance as appropriate.
    (c) For each control period in 2009 and thereafter, the 
Administrator will allocate CAIR NOX allowances to CAIR 
NOX units in a State that are not allocated CAIR 
NOX allowances under paragraph (b) of this section because

[[Page 91]]

the units do not yet have a baseline heat input under paragraph (a) of 
this section or because the units have a baseline heat input but all 
CAIR NOX allowances available under paragraph (b) of this 
section for the control period are already allocated, in accordance with 
the following procedures:
    (1) The Administrator will establish a separate new unit set-aside 
for each control period. Each new unit set-aside will be allocated CAIR 
NOX allowances equal to 5 percent for a control period in 
2009 through 2014, and 3 percent for a control period in 2015 and 
thereafter, of the amount of tons of NOX emissions in the 
applicable State trading budget under Sec. 97.140.
    (2) The CAIR designated representative of such a CAIR NOX 
unit may submit to the Administrator a request, in a format specified by 
the Administrator, to be allocated CAIR NOX allowances, 
starting with the later of the control period in 2009 or the first 
control period after the control period in which the CAIR NOX 
unit commences commercial operation and until the first control period 
for which the unit is allocated CAIR NOX allowances under 
paragraph (b) of this section. A separate CAIR NOX allowance 
allocation request for each control period for which CAIR NOX 
allowances are sought must be submitted on or before May 1 of such 
control period and after the date on which the CAIR NOX unit 
commences commercial operation.
    (3) In a CAIR NOX allowance allocation request under 
paragraph (c)(2) of this section, the CAIR designated representative may 
request for a control period CAIR NOX allowances in an amount 
not exceeding the CAIR NOX unit's total tons of 
NOX emissions during the calendar year immediately before 
such control period.
    (4) The Administrator will review each CAIR NOX allowance 
allocation request under paragraph (c)(2) of this section and will 
allocate CAIR NOX allowances for each control period pursuant 
to such request as follows:
    (i) The Administrator will accept an allowance allocation request 
only if the request meets, or is adjusted by the Administrator as 
necessary to meet, the requirements of paragraphs (c)(2) and (3) of this 
section.
    (ii) On or after May 1 of the control period, the Administrator will 
determine the sum of the CAIR NOX allowances requested (as 
adjusted under paragraph (c)(4)(i) of this section) in all allowance 
allocation requests accepted under paragraph (c)(4)(i) of this section 
for the control period.
    (iii) If the amount of CAIR NOX allowances in the new 
unit set-aside for the control period is greater than or equal to the 
sum under paragraph (c)(4)(ii) of this section, then the Administrator 
will allocate the amount of CAIR NOX allowances requested (as 
adjusted under paragraph (c)(4)(i) of this section) to each CAIR 
NOX unit covered by an allowance allocation request accepted 
under paragraph (c)(4)(i) of this section.
    (iv) If the amount of CAIR NOX allowances in the new unit 
set-aside for the control period is less than the sum under paragraph 
(c)(4)(ii) of this section, then the Administrator will allocate to each 
CAIR NOX unit covered by an allowance allocation request 
accepted under paragraph (c)(4)(i) of this section the amount of the 
CAIR NOX allowances requested (as adjusted under paragraph 
(c)(4)(i) of this section), multiplied by the amount of CAIR 
NOX allowances in the new unit set-aside for the control 
period, divided by the sum determined under paragraph (c)(4)(ii) of this 
section, and rounded to the nearest whole allowance as appropriate.
    (v) The Administrator will notify each CAIR designated 
representative that submitted an allowance allocation request of the 
amount of CAIR NOX allowances (if any) allocated for the 
control period to the CAIR NOX unit covered by the request.
    (d) If, after completion of the procedures under paragraph (c)(4) of 
this section for a control period, any unallocated CAIR NOX 
allowances remain in the new unit set-aside under paragraph (c) of this 
section for a State for the control period, the Administrator will 
allocate to each CAIR NOX unit that was allocated CAIR 
NOX allowances under paragraph (b) of this section in the 
State an amount of CAIR NOX allowances equal to the total 
amount of such remaining unallocated CAIR NOX allowances, 
multiplied by the unit's allocation

[[Page 92]]

under paragraph (b) of this section, divided by 95 percent for a control 
period during 2009 through 2014, and 97 percent for a control period 
during 2015 and thereafter, of the amount of tons of NOX 
emissions in the applicable State trading budget under Sec. 97.140, and 
rounded to the nearest whole allowance as appropriate.
    (e) If the Administrator determines that CAIR NOX 
allowances were allocated under paragraphs (a) and (b) of this section, 
paragraphs (a) and (c) of this section, or paragraph (d) of this section 
for a control period and that the recipient of the allocation is not 
actually a CAIR NOX unit under Sec. 97.104 in such control 
period, then the Administrator will notify the CAIR designated 
representative and will act in accordance with the following procedures:
    (1) Except as provided in paragraph (e)(2) or (3) of this section, 
the Administrator will not record such CAIR NOX allowances 
under Sec. 97.153.
    (2) If the Administrator already recorded such CAIR NOX 
allowances under Sec. 97.153 and if the Administrator makes such 
determination before making deductions for the source that includes such 
recipient under Sec. 97.154(b) for the control period, then the 
Administrator will deduct from the account in which such CAIR 
NOX allowances were recorded under Sec. 97.153 an amount of 
CAIR NOX allowances allocated for the same or a prior control 
period equal to the amount of such already recorded CAIR NOX 
allowances. The CAIR designated representative shall ensure that there 
are sufficient CAIR NOX allowances in such account for 
completion of the deduction.
    (3) If the Administrator already recorded such CAIR NOX 
allowances under Sec. 97.153 and if the Administrator makes such 
determination after making deductions for the source that includes such 
recipient under Sec. 97.154(b) for the control period, then the 
Administrator will apply paragraph (e)(1) or (2) of this section, as 
appropriate, to any subsequent control period for which CAIR 
NOX allowances were allocated to such recipient.
    (4) The Administrator will transfer the CAIR NOX 
allowances that are not recorded, or that are deducted, in accordance 
with paragraphs (e)(1), (2), and (3) of this section to a new unit set-
aside for the State in which such recipient is located.



Sec. 97.143  Compliance supplement pool.

    (a) In addition to the CAIR NOX allowances allocated 
under Sec. 97.142, the Administrator may allocate for the control 
period in 2009 up to the following amount of CAIR NOX 
allowances to CAIR NOX units in the respective State:

    (b) For any CAIR NOX unit in a State, if the unit's 
average annual NOX emission rate for 2007 or 2008 is less 
than 0.25 lb/mmBtu and, where such unit is included in a NOX 
averaging plan under Sec. 76.11 of this chapter under the Acid Rain 
Program for such year, the unit's NOX averaging plan has an 
actual weighted average NOX emission rate for such year equal 
to or less than the actual weighted average NOX emission rate 
for the year before such year and if the unit achieves NOX 
emission reductions in 2007 and 2008, the CAIR designated representative 
of the unit may request early reduction credits, and allocation of CAIR 
NOX allowances from the compliance supplement pool under 
paragraph (a) of this section for

[[Page 93]]

such early reduction credits, in accordance with the following:
    (1) The owners and operators of such CAIR NOX unit shall 
monitor and report the NOX emissions rate and the heat input 
of the unit in accordance with subpart HH of this part in each control 
period for which early reduction credit is requested.
    (2) The CAIR designated representative of such CAIR NOX 
unit shall submit to the Administrator by May 1, 2009 a request, in a 
format specified by the Administrator, for allocation of an amount of 
CAIR NOX allowances from the compliance supplement pool not 
exceeding the sum of the unit's heat input for the control period in 
2007 multiplied by the difference (if any greater than zero) between 
0.25 lb/mmBtu and the unit's NOX emission rate for the 
control period in 2007 plus the unit's heat input for the control period 
in 2008 multiplied by the difference (if any greater than zero) between 
0.25 lb/mmBtu and the unit's NOX emission rate for the 
control period in 2008, determined in accordance with subpart HH of this 
part and with the sum divided by 2,000 lb/ton and rounded to the nearest 
whole number of tons as appropriate.
    (c) For any CAIR NOX unit in a State whose compliance 
with the CAIR NOX emissions limitation for the control period 
in 2009 would create an undue risk to the reliability of electricity 
supply during such control period, the CAIR designated representative of 
the unit may request the allocation of CAIR NOX allowances 
from the compliance supplement pool under paragraph (a) of this section, 
in accordance with the following:
    (1) The CAIR designated representative of such CAIR NOX 
unit shall submit to the Administrator by May 1, 2009 a request, in a 
format specified by the Administrator, for allocation of an amount of 
CAIR NOX allowances from the compliance supplement pool not 
exceeding the minimum amount of CAIR NOX allowances necessary 
to remove such undue risk to the reliability of electricity supply.
    (2) In the request under paragraph (c)(1) of this section, the CAIR 
designated representative of such CAIR NOX unit shall 
demonstrate that, in the absence of allocation to the unit of the amount 
of CAIR NOX allowances requested, the unit's compliance with 
the CAIR NOX emissions limitation for the control period in 
2009 would create an undue risk to the reliability of electricity supply 
during such control period. This demonstration must include a showing 
that it would not be feasible for the owners and operators of the unit 
to:
    (i) Obtain a sufficient amount of electricity from other electricity 
generation facilities, during the installation of control technology at 
the unit for compliance with the CAIR NOX emissions 
limitation, to prevent such undue risk; or
    (ii) Obtain under paragraphs (b) and (d) of this section, or 
otherwise obtain, a sufficient amount of CAIR NOX allowances 
to prevent such undue risk.
    (d) The Administrator will review each request under paragraph (b) 
or (c) of this section submitted by May 1, 2009 and will allocate CAIR 
NOX allowances for the control period in 2009 to CAIR 
NOX units in a State and covered by such request as follows:
    (1) Upon receipt of each such request, the Administrator will make 
any necessary adjustments to the request to ensure that the amount of 
the CAIR NOX allowances requested meets the requirements of 
paragraph (b) or (c) of this section.
    (2) If the State's compliance supplement pool under paragraph (a) of 
this section has an amount of CAIR NOX allowances not less 
than the total amount of CAIR NOX allowances in all such 
requests (as adjusted under paragraph (d)(1) of this section), the 
Administrator will allocate to each CAIR NOX unit covered by 
such requests the amount of CAIR NOX allowances requested (as 
adjusted under paragraph (d)(1) of this section).
    (3) If the State's compliance supplement pool under paragraph (a) of 
this section has a smaller amount of CAIR NOX allowances than 
the total amount of CAIR NOX allowances in all such requests 
(as adjusted under paragraph (d)(1) of this section), the Administrator 
will allocate CAIR NOX allowances to each CAIR NOX 
unit covered by such requests according to the following formula and 
rounding to the

[[Page 94]]

nearest whole allowance as appropriate:

Unit's allocation = Unit's adjusted allocation x (State's compliance 
supplement pool / Total adjusted allocations for all units)

Where:

``Unit's allocation'' is the amount of CAIR NOX allowances 
          allocated to the unit from the State's compliance supplement 
          pool.
``Unit's adjusted allocation'' is the amount of CAIR NOX 
          allowances requested for the unit under paragraph (b) or (c) 
          of this section, as adjusted under paragraph (d)(1) of this 
          section.
``State's compliance supplement pool'' is the amount of CAIR 
          NOX allowances in the State's compliance supplement 
          pool.
``Total adjusted allocations for all units'' is the sum of the amounts 
          of allocations requested for all units under paragraph (b) or 
          (c) of this section, as adjusted under paragraph (d)(1) of 
          this section.

    (4) By July 31, 2009, the Administrator will determine by order the 
allocations under paragraph (d)(2) or (3) of this section. The 
Administrator will make available to the public each determination of 
CAIR NOX allowances under such paragraph and will provide an 
opportunity for submission of objections to the determination. 
Objections shall be limited to addressing whether the determination is 
in accordance with paragraph (b) or (c) of this section and paragraph 
(d)(2) or (3) of this section, as appropriate. Based on any such 
objections, the Administrator will adjust each determination to the 
extent necessary to ensure that it is in accordance with such 
paragraphs.
    (5) By January 1, 2010, the Administrator will record the 
allocations under paragraph (d)(4) of this section.

    (a) Allowance transfer deadline. The CAIR NOX allowances 
are available to be deducted for compliance with a source's CAIR 
NOX emissions limitation for a control period in a given 
calendar year only if the CAIR NOX allowances:
    (1) Were allocated for the control period in the year or a prior 
year; and
    (2) Are held in the compliance account as of the allowance transfer 
deadline for the control period or are transferred into the compliance 
account by a CAIR NOX allowance transfer correctly submitted 
for recordation under Sec. Sec. 97.160 and 97.161 by the allowance 
transfer deadline for the control period.
    (b) Deductions for compliance. Following the recordation, in 
accordance with Sec. 97.161, of CAIR NOX allowance transfers 
submitted for recordation in a source's compliance account by the 
allowance transfer deadline for a control period, the Administrator will 
deduct from the compliance account CAIR NOX allowances 
available under paragraph (a) of this section in order to determine 
whether the source meets the CAIR NOX emissions limitation

    (d) Deductions for excess emissions. (1) After making the deductions 
for compliance under paragraph (b) of this section for a control period 
in a calendar year in which the CAIR NOX source has excess 
emissions, the Administrator will deduct from the source's compliance 
account an amount of CAIR NOX allowances, allocated for the 
control

[[Page 100]]

period in the immediately following calendar year, equal to 3 times the 
number of tons of the source's excess emissions.
    (2) Any allowance deduction required under paragraph (d)(1) of this 
section shall not affect the liability of the owners and operators of 
the CAIR NOX source or the CAIR NOX units at the 
source for any fine, penalty, or assessment, or their obligation to 
comply with any other remedy, for the same violations, as ordered under 
the Clean Air Act or applicable State law.

record NOX mass emissions or heat input rate or to meet the 
quality-assurance and quality-control requirements of Sec. 75.21 of 
this chapter or appendix B to part 75 of this chapter, the owner or 
operator shall recertify the monitoring system in accordance with Sec. 
75.20(b) of this chapter. Furthermore, whenever the owner or operator 
makes a replacement, modification, or change to the flue gas handling 
system or the unit's operation that may significantly change the stack 
flow or concentration profile, the owner or operator shall recertify 
each continuous emission monitoring system whose accuracy is potentially 
affected by the change, in accordance with Sec. 75.20(b) of this 
chapter. Examples of changes to a continuous

[[Page 104]]

emission monitoring system that require recertification include 
replacement of the analyzer, complete replacement of an existing 
continuous emission monitoring system, or change in location or 
orientation of the sampling probe or site. Any fuel flowmeter system, 
and any excepted NOX monitoring system under appendix E to 
part 75 of this chapter, under Sec. 97.170(a)(1) are subject to the 
recertification requirements in Sec. 75.20(g)(6) of this chapter.

Paragraphs (d)(3)(i) through (iv) of this section apply to both initial 
certification and recertification of a continuous monitoring system 
under Sec. 97.170(a)(1). For recertifications, replace the words 
``certification'' and ``initial certification'' with the word 
``recertification'', replace the word ``certified'' with the word 
``recertified'', and follow the procedures in Sec. Sec. 75.20(b)(5) and 
(g)(7) of this chapter in lieu of the procedures in paragraph (d)(3)(v) 
of this section.
    (i) Notification of certification. The CAIR designated 
representative shall submit to the appropriate EPA Regional Office and 
the Administrator written notice of the dates of certification testing, 
in accordance with Sec. 97.173.
    (ii) Certification application. The CAIR designated representative 
shall submit to the Administrator a certification application for each 
monitoring system. A complete certification application shall include

    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CAIR NOX Annual Trading Program 
for a period not to exceed 120 days after receipt by the Administrator 
of the complete certification application for the monitoring system 
under paragraph (d)(3)(ii) of this section. Data measured and recorded 
by the provisionally certified monitoring system, in accordance with the 
requirements of part 75 of this chapter, will be considered valid 
quality-assured data (retroactive to the date and time of provisional 
certification), provided that the Administrator does not invalidate the 
provisional certification by issuing a notice of disapproval within 120 
days of the date of receipt of the complete certification application by 
the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph 
(d)(3)(ii) of this section. In the event the Administrator does not 
issue such a notice within such 120-day period, each monitoring system 
that meets the applicable performance requirements of part 75 of this 
chapter and is included in the certification application will be deemed 
certified for use under the CAIR NOX Annual Trading Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the CAIR designated 
representative must submit the additional information required to 
complete the certification application. If the CAIR designated 
representative does not comply with the notice of incompleteness by the 
specified date, then the Administrator may issue a notice of disapproval 
under paragraph (d)(3)(iv)(C) of this section. The 120-day review period 
shall not begin before receipt of a complete certification application.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue

[[Page 105]]

a written notice of disapproval of the certification application. Upon 
issuance of such notice of disapproval, the provisional certification is 
invalidated by the Administrator and the data measured and recorded by 
each uncertified monitoring system shall not be considered valid 
quality-assured data beginning with the date and hour of provisional 
certification (as defined under Sec. 75.20(a)(3) of this chapter). The 
owner or operator shall follow the procedures for loss of certification 
in paragraph (d)(3)(v) of this section for each monitoring system that 
is disapproved for initial certification.

issues a notice of disapproval of a certification application under 
paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (d)(3)(iv)(D) of this section, 
then:
    (A) The owner or operator shall substitute the following values, for 
each disapproved monitoring system, for each hour of unit operation 
during the period of invalid data specified under Sec. 
75.20(a)(4)(iii), Sec. 75.20(g)(7), or Sec. 75.21(e) of this chapter 
and continuing until the applicable date and hour specified under Sec. 
75.20(a)(5)(i) or (g)(7) of this chapter:
    (1) For a disapproved NOX emission rate (i.e.,, 
NOX-diluent) system, the maximum potential NOX 
emission rate, as defined in Sec. 72.2 of this chapter.
    (2) For a disapproved NOX pollutant concentration monitor 
and disapproved flow monitor, respectively, the maximum potential 
concentration of NOX and the maximum potential flow rate, as 
defined in sections 2.1.2.1 and 2.1.4.1 of appendix A to part 75 of this 
chapter.
    (3) For a disapproved moisture monitoring system and disapproved 
diluent gas monitoring system, respectively, the minimum potential 
moisture percentage and either the maximum potential CO2 
concentration or the minimum potential O2 concentration (as 
applicable), as defined in sections 2.1.5, 2.1.3.1, and 2.1.3.2 of 
appendix A to part 75 of this chapter.
    (4) For a disapproved fuel flowmeter system, the maximum potential 
fuel flow rate, as defined in section 2.4.2.1 of appendix D to part 75

the applicable missing data procedures in subpart D or subpart H of, or

[[Page 106]]

appendix D or appendix E to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.171 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the permitting authority or 
the Administrator. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.171 for 
each disapproved monitoring system.

NOX emission controls during any such control periods, the 
average of the amounts of the unit's NOX emissions rate (in 
lb/mmBtu) for such control periods during which the unit has add-on 
NOX emission controls.
    (e) Issuance of CAIR opt-in permit. After calculating the baseline 
heat input and the baseline NOX emissions rate for the unit 
under paragraphs (c) and (d) of this section and if the permitting 
authority determines that the CAIR designated representative shows that 
the unit meets the requirements for a CAIR NOX opt-in unit in 
Sec. 97.180 and meets the elements certified in Sec. 97.183(a)(2), the 
permitting authority will issue a CAIR opt-in permit. The permitting 
authority will provide a copy of the CAIR opt-in permit to the 
Administrator, who will then establish a compliance account for the 
source that includes the CAIR NOX opt-in unit unless the 
source already has a compliance account.
    (f) Issuance of denial of CAIR opt-in permit. Notwithstanding 
paragraphs (a) through (e) of this section, if at any time before 
issuance of a CAIR opt-in

[[Page 110]]

permit for the unit, the permitting authority determines that the CAIR 
designated representative fails to show that the unit meets the 
requirements for a CAIR NOX opt-in unit in Sec. 97.180 or 
meets the elements certified in Sec. 97.183(a)(2), the permitting 
authority will issue a denial of a CAIR opt-in permit for the unit.
    (g) Date of entry into CAIR NOX Annual Trading Program. A 
unit for which an initial CAIR opt-in permit is issued by the permitting 
authority shall become a CAIR NOX opt-in unit, and a CAIR 
NOX unit, as of the later of January 1, 2009 or January 1 of 
the first control period during which such CAIR opt-in permit is issued.
    (h) Repowered CAIR NOX opt-in unit. (1) If CAIR 
designated representative requests, and the permitting authority issues 
a CAIR opt-in permit providing for, allocation to a CAIR NOX 
opt-in unit of CAIR NOX allowances under Sec. 97.188(c) and 
such unit is repowered after its date of entry into the CAIR 
NOX Annual Trading Program under paragraph (g) of this 
section, the repowered unit shall be treated as a CAIR NOX 
opt-in unit replacing the original CAIR NOX opt-in unit, as 
of the date of start-up of the repowered unit's combustion chamber.
    (2) Notwithstanding paragraphs (c) and (d) of this section, as of 
the date of start-up under paragraph (h)(1) of this section, the 
repowered unit shall be deemed to have the same date of commencement of 
operation, date of commencement of commercial operation, baseline heat 
input, and baseline NOX emission rate as the original CAIR 
NOX opt-in unit, and the original CAIR NOX opt-in 
unit shall no longer be treated as a CAIR NOX opt-in unit or 
a CAIR NOX unit.

Sec. 97.186  Withdrawal from CAIR NOX Annual Trading Program.

    Except as provided under paragraph (g) of this section, a CAIR 
NOX opt-in unit may withdraw from the CAIR NOX 
Annual Trading Program, but only if the permitting authority issues a 
notification to the CAIR designated representative of the CAIR 
NOX opt-in unit of the acceptance of the withdrawal of the 
CAIR NOX opt-in unit in accordance with paragraph (d) of this 
section.
    (a) Requesting withdrawal. In order to withdraw a CAIR 
NOX opt-in unit from the CAIR NOX Annual Trading 
Program, the CAIR designated representative of the CAIR NOX 
opt-in unit shall submit to the permitting authority a request to 
withdraw effective as of midnight of December 31 of a specified calendar 
year, which date must be at least 4 years after December 31 of the year 
of entry into the CAIR NOX Annual Trading Program under Sec. 
97.184(g).

[[Page 111]]

The request must be submitted no later than 90 days before the requested 
effective date of withdrawal.
    (b) Conditions for withdrawal. Before a CAIR NOX opt-in 
unit covered by a request under paragraph (a) of this section may 
withdraw from the CAIR NOX Annual Trading Program and the 
CAIR opt-in permit may be terminated under paragraph (e) of this 
section, the following conditions must be met:
    (1) For the control period ending on the date on which the 
withdrawal is to be effective, the source that includes the CAIR 
NOX opt-in unit must meet the requirement to hold CAIR 
NOX allowances under Sec. 97.106(c) and cannot have any 
excess emissions.
    (2) After the requirement for withdrawal under paragraph (b)(1) of 
this section is met, the Administrator will deduct from the compliance 
account of the source that includes the CAIR NOX opt-in unit 
CAIR NOX allowances equal in amount to and allocated for the 
same or a prior control period as any CAIR NOX allowances 
allocated to the CAIR NOX opt-in unit under Sec. 97.188 for 
any control period for which the withdrawal is to be effective. If there 
are no remaining CAIR NOX units at the source, the 
Administrator will close the compliance account, and the owners and 
operators of the CAIR NOX opt-in unit may submit a CAIR 
NOX allowance transfer for any remaining CAIR NOX 
allowances to another CAIR NOX Allowance Tracking System in 
accordance with subpart GG of this part.
    (c) Notification. (1) After the requirements for withdrawal under 
paragraphs (a) and (b) of this section are met (including deduction of 
the full amount of CAIR NOX allowances required), the 
permitting authority will issue a notification to the CAIR designated 
representative of the CAIR NOX opt-in unit of the acceptance 
of the withdrawal of the CAIR NOX opt-in unit as of midnight 
on December 31 of the calendar year for which the withdrawal was 
requested.
    (2) If the requirements for withdrawal under paragraphs (a) and (b) 
of this section are not met, the permitting authority will issue a 
notification to the CAIR designated representative of the CAIR 
NOX opt-in unit that the CAIR NOX opt-in unit's 
request to withdraw is denied. Such CAIR NOX opt-in unit 
shall continue to be a CAIR NOX opt-in unit.
    (d) Permit amendment. After the permitting authority issues a 
notification under paragraph (c)(1) of this section that the 
requirements for withdrawal have been met, the permitting authority will 
revise the CAIR permit covering the CAIR NOX opt-in unit to 
terminate the CAIR opt-in permit for such unit as of the effective date 
specified under paragraph (c)(1) of this section. The unit shall 
continue to be a CAIR NOX opt-in unit until the effective 
date of the termination and shall comply with all requirements under the 
CAIR NOX Annual Trading Program concerning any control 
periods for which the unit is a CAIR NOX opt-in unit, even if 
such requirements arise or must be complied with after the withdrawal 
takes effect.
    (e) Reapplication upon failure to meet conditions of withdrawal. If 
the permitting authority denies the CAIR NOX opt-in unit's 
request to withdraw, the CAIR designated representative may submit 
another request to withdraw in accordance with paragraphs (a) and (b) of 
this section.
    (f) Ability to reapply to the CAIR NOX Annual Trading 
Program. Once a CAIR NOX opt-in unit withdraws from the CAIR 
NOX Annual Trading Program and its CAIR opt-in permit is 
terminated under this section, the CAIR designated representative may 
not submit another application for a CAIR opt-in permit under Sec. 
97.183 for such CAIR NOX opt-in unit before the date that is 
4 years after the date on which the withdrawal became effective. Such 
new application for a CAIR opt-in permit will be treated as an initial 
application for a CAIR opt-in permit under Sec. 97.184.
    (g) Inability to withdraw. Notwithstanding paragraphs (a) through 
(f) of this section, a CAIR NOX opt-in unit shall not be 
eligible to withdraw from the CAIR NOX Annual Trading Program 
if the CAIR designated representative of the CAIR NOX opt-in 
unit requests, and the permitting authority issues a CAIR NOX 
opt-in permit providing for, allocation to the CAIR NOX opt-
in unit of CAIR NOX allowances under Sec. 97.188(c).

[[Page 112]]



Sec. 97.187  Change in regulatory status.

    (a) Notification. If a CAIR NOX opt-in unit becomes a 
CAIR NOX unit under Sec. 97.104, then the CAIR designated 
representative shall notify in writing the permitting authority and the 
Administrator of such change in the CAIR NOX opt-in unit's 
regulatory status, within 30 days of such change.
    (b) Permitting authority's and Administrator's actions. (1) If a 
CAIR NOX opt-in unit becomes a CAIR NOX unit under 
Sec. 97.104, the permitting authority will revise the CAIR 
NOX opt-in unit's CAIR opt-in permit to meet the requirements 
of a CAIR permit under Sec. 97.123, and remove the CAIR opt-in permit 
provisions, as of the date on which the CAIR NOX opt-in unit 
becomes a CAIR NOX unit under Sec. 97.104.
    (2)(i) The Administrator will deduct from the compliance account of 
the source that includes the CAIR NOX opt-in unit that 
becomes a CAIR NOX unit under Sec. 97.104, CAIR 
NOX allowances equal in amount to and allocated for the same 
or a prior control period as:
    (A) Any CAIR NOX allowances allocated to the CAIR 
NOX opt-in unit under Sec. 97.188 for any control period 
after the date on which the CAIR NOX opt-in unit becomes a 
CAIR NOX unit under Sec. 97.104; and
    (B) If the date on which the CAIR NOX opt-in unit becomes 
a CAIR NOX unit under Sec. 97.104 is not December 31, the 
CAIR NOX allowances allocated to the CAIR NOX opt-
in unit under Sec. 97.188 for the control period that includes the date 
on which the CAIR NOX opt-in unit becomes a CAIR 
NOX unit under Sec. 97.104, multiplied by the ratio of the 
number of days, in the control period, starting with the date on which 
the CAIR NOX opt-in unit becomes a CAIR NOX unit 
under Sec. 97.104 divided by the total number of days in the control 
period and rounded to the nearest whole allowance as appropriate.
    (ii) The CAIR designated representative shall ensure that the 
compliance account of the source that includes the CAIR NOX 
opt-in unit that becomes a CAIR NOX unit under Sec. 97.104 
contains the CAIR NOX allowances necessary for completion of 
the deduction under paragraph (b)(2)(i) of this section.
    (3)(i) For every control period after the date on which the CAIR 
NOX opt-in unit becomes a CAIR NOX unit under 
Sec. 97.104, the CAIR NOX opt-in unit will be allocated CAIR 
NOX allowances under Sec. 97.142.
    (ii) If the date on which the CAIR NOX opt-in unit 
becomes a CAIR NOX unit under Sec. 97.104 is not December 
31, the following amount of CAIR NOX allowances will be 
allocated to the CAIR NOX opt-in unit (as a CAIR 
NOX unit) under (97.142 for the control period that includes 
the date on which the CAIR NOX opt-in unit becomes a CAIR 
NOX unit under Sec. 97.104:
    (A) The amount of CAIR NOX allowances otherwise allocated 
to the CAIR NOX opt-in unit (as a CAIR NOX unit) 
under Sec. 97.142 for the control period multiplied by;
    (B) The ratio of the number of days, in the control period, starting 
with the date on which the CAIR NOX opt-in unit becomes a 
CAIR NOX unit under Sec. 97.104, divided by the total number 
of days in the control period; and
    (C) Rounded to the nearest whole allowance as appropriate.

SO2 Trading Program, a CAIR permit application, a CAIR 
permit, or an exemption under Sec. 97.205 shall be construed as 
exempting or excluding the owners and operators, and the CAIR designated 
representative, of a CAIR SO2 source or CAIR SO2 
unit from compliance with any other provision of the applicable, 
approved State implementation plan, a federally enforceable permit, or 
the Clean Air Act.



Sec. 97.207  Computation of time.

Sec. 97.253  Recordation of CAIR SO2 allowances.

    (a)(1) After a compliance account is established under Sec. 
97.251(a) or Sec. 73.31(a) or (b) of this chapter, the Administrator 
will record in the compliance account any CAIR SO2 allowance 
allocated to any CAIR SO2 unit at the source for each of the 
30 years starting the later of 2010 or the year in which the compliance 
account is established and any CAIR SO2 allowance allocated 
for each of the 30 years starting the later of 2010 or the year in which 
the compliance account is established and transferred to the source in 
accordance with subpart GGG of this part or subpart D of part 73 of this 
chapter.
    (2) In 2011 and each year thereafter, after Administrator has 
completed all deductions under Sec. 97.254(b), the Administrator will 
record in the compliance account any CAIR SO2 allowance 
allocated to any CAIR SO2 unit at the source for the new 30th 
year (i.e., the year that is 30 years after the calendar year for which 
such deductions are or could be made) and any CAIR SO2 
allowance allocated for the new 30th year and transferred to the source 
in accordance with subpart GGG of this part or subpart D of part 73 of 
this chapter.
    (b)(1) After a general account is established under Sec. 97.251(b)

authority under

[[Page 136]]

Sec. 97.288, the Administrator will assign each such CAIR 
SO2 allowance a unique identification number that will 
include digits identifying the year of the control period for which the 
CAIR SO2 allowance is allocated.



Sec. 97.254  Compliance with CAIR SO2 emissions limitation.

    (a) Allowance transfer deadline. The CAIR SO2 allowances 
are available to be deducted for compliance with a source's CAIR 
SO2 emissions limitation for a control period in a given 
calendar year only if the CAIR SO2 allowances:
    (1) Were allocated for the control period in the year or a prior 
year; and
    (2) Are held in the compliance account as of the allowance transfer 
deadline for the control period or are transferred into the compliance 
account by a CAIR SO2 allowance transfer correctly submitted 
for recordation under Sec. Sec. 97.260 and 97.261 by the allowance 
transfer deadline for the control period.
    (b) Deductions for compliance. Following the recordation, in 
accordance with Sec. 97.261, of CAIR SO2 allowance transfers 
submitted for recordation in a source's compliance account by the 
allowance transfer deadline for a control period, the Administrator will 
deduct from the compliance account CAIR SO2 allowances 
available under paragraph (a) of this section in order to determine 
whether the source meets the CAIR SO2 emissions limitation 
for the control period as follows:
    (1) For a CAIR SO2 source subject to an Acid Rain 
emissions limitation, the Administrator will, in the following order:
    (i) Deduct the amount of CAIR SO2 allowances, available 
under paragraph (a) of this section and not issued by a permitting 
authority under Sec. 97.288, that is required under Sec. Sec. 73.35(b) 
and (c) of this part. If there are sufficient CAIR SO2 
allowances to complete this deduction, the deduction will be treated as 
satisfying the requirements of Sec. Sec. 73.35(b) and (c) of this 
chapter.
    (ii) Deduct the amount of CAIR SO2 allowances, not issued 
by a permitting authority under Sec. 97.288, that is required under 
Sec. Sec. 73.35(d) and 77.5 of this part. If there are sufficient CAIR 
SO2 allowances to complete this deduction, the deduction will 
be treated as satisfying the requirements of Sec. Sec. 73.35(d) and 
77.5 of this chapter.
    (iii) Treating the CAIR SO2 allowances deducted under 
paragraph (b)(1)(i) of this section as also being deducted under this 
paragraph (b)(1)(iii), deduct CAIR SO2 allowances available 
under paragraph (a) of this section (including any issued by a 
permitting authority under Sec. 97.288) in order to determine whether 
the source meets the CAIR SO2 emissions limitation for the 
control period, as follows:
    (A) Until the tonnage equivalent of the CAIR SO2 
allowances deducted equals, or exceeds in accordance with paragraphs 
(c)(1) and (2) of this section, the number of tons of total sulfur 
dioxide emissions, determined in accordance with subpart HHH of this 
part, from all CAIR SO2 units at the source for the control 
period; or
    (B) If there are insufficient CAIR SO2 allowances to 
complete the deductions in paragraph (b)(1)(iii)(A) of this section, 
until no more CAIR SO2 allowances available under paragraph 
(a) of this section (including any issued by a permitting authority 
under Sec. 97.288) remain in the compliance account.
    (2) For a CAIR SO2 source not subject to an Acid Rain 
emissions limitation, the Administrator will deduct CAIR SO2 
allowances available under paragraph (a) of this section (including any 
issued by a permitting authority under Sec. 97.288) in order to 
determine whether the source meets the CAIR SO2 emissions 
limitation for the control period, as follows:
    (i) Until the tonnage equivalent of the CAIR SO2 
allowances deducted equals, or exceeds in accordance with paragraphs 
(c)(1) and (2) of this section, the number of tons of total sulfur 
dioxide emissions, determined in accordance with subpart HHH of this 
part, from all CAIR SO2 units at the source for the control 
period; or
    (ii) If there are insufficient CAIR SO2 allowances to 
complete the deductions in paragraph (b)(2)(i) of this section, until no 
more CAIR SO2 allowances available under paragraph (a) of 
this section (including any issued by a permitting authority under Sec. 
97.288) remain in the compliance account.

[[Page 137]]

    (c)(1) Identification of CAIR SO2 allowances by serial 
number. The CAIR authorized account representative for a source's 
compliance account may request that specific CAIR SO2 
allowances, identified by serial number, in the compliance account be 
deducted for emissions or excess emissions for a control period in 
accordance with paragraph (b) or (d) of this section. Such request shall 
be submitted to the Administrator by the allowance transfer deadline for 
the control period and include, in a format prescribed by the 
Administrator, the identification of the CAIR SO2 source and 
the appropriate serial numbers.
    (2) First-in, first-out. The Administrator will deduct CAIR 
SO2 allowances under paragraph (b) or (d) of this section 
from the source's compliance account, in the absence of an 
identification or in the case of a partial identification of CAIR 
SO2 allowances by serial number under paragraph (c)(1) of 
this section, on a first-in, first-out (FIFO) accounting basis in the 
following order:
    (i) Any CAIR SO2 allowances that were allocated to the 
units at the source for a control period before 2010, in the order of 
recordation;
    (ii) Any CAIR SO2 allowances that were allocated to any 
entity for a control period before 2010 and transferred and recorded in 
the compliance account pursuant to subpart GGG of this part or subpart D 
of part 73 of this chapter, in the order of recordation;
    (iii) Any CAIR SO2 allowances that were allocated to the 
units at the source for a control period during 2010 through 2014, in 
the order of recordation;
    (iv) Any CAIR SO2 allowances that were allocated to any 
entity for a control period during 2010 through 2014 and transferred and 
recorded in the compliance account pursuant to subpart GGG of this part 
or subpart D of part 73 of this chapter, in the order of recordation;
    (v) Any CAIR SO2 allowances that were allocated to the 
units at the source for a control period in 2015 or later, in the order 
of recordation; and
    (vi) Any CAIR SO2 allowances that were allocated to any 
entity for a control period in 2015 or later and transferred and 
recorded in the compliance account pursuant to subpart GGG of this part 
or subpart D of part 73 of this chapter, in the order of recordation.
    (d) Deductions for excess emissions. (1) After making the deductions 
for compliance under paragraph (b) of this section for a control period 
in a calendar year in which the CAIR SO2 source has excess 
emissions, the Administrator will deduct from the source's compliance 
account the tonnage equivalent in CAIR SO2 allowances, 
allocated for the control period in the immediately following calendar 
year (including any issued by a permitting authority under Sec. 
97.288), equal to, or exceeding in accordance with paragraphs (c)(1) and 
(2) of this section 3 times the following amount: the number of tons of 
the source's excess emissions minus, if the source is subject to an Acid 
Rain emissions limitation, the amount of the CAIR SO2 
allowances required to be deducted under paragraph (b)(1)(ii) of this 
section.
    (2) Any allowance deduction required under paragraph (d)(1) of this 
section shall not affect the liability of the owners and operators of 
the CAIR SO2 source or the CAIR SO2 units at the 
source for any fine, penalty, or assessment, or their obligation to 
comply with any other remedy, for the same violations, as ordered under 
the Clean Air Act or applicable State law.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section and subpart III.
    (f) Administrator's action on submissions. (1) The Administrator may 
review and conduct independent audits concerning any submission under 
the CAIR SO2 Trading Program and make appropriate adjustments

system may be used under the CAIR SO2 Trading Program for a 
period not to exceed 120 days after receipt by the Administrator of the 
complete certification application for the monitoring system under 
paragraph (d)(3)(ii) of this section. Data measured and recorded by the 
provisionally certified monitoring system, in accordance with the 
requirements of part 75 of this chapter, will be considered valid 
quality-assured data (retroactive to the date and time of provisional 
certification), provided that the Administrator does not invalidate the 
provisional certification by issuing a notice of disapproval within 120 
days of the date of receipt of the complete certification application by 
the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph

    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the CAIR designated 
representative must submit the additional information required to 
complete the certification application. If the CAIR designated 
representative does not comply with the notice of incompleteness by the 
specified date, then the Administrator may issue a notice of disapproval 
under paragraph (d)(3)(iv)(C) of this section. The 120-day review period 
shall not begin before receipt of a complete certification application.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter). The owner or operator 
shall follow the procedures for loss of certification in paragraph 
(d)(3)(v) of this section for each

applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the permitting authority or 
the Administrator. By issuing the

[[Page 144]]

notice of disapproval, the Administrator revokes prospectively the 
certification status of the monitoring system. The data measured and 
recorded by the monitoring system shall not be considered valid quality-
assured data from the date of issuance of the notification of the 
revoked certification status until the date and time that the owner or 
operator completes subsequently approved initial certification or 
recertification tests for the monitoring system. The owner or operator 
shall follow the applicable initial certification or recertification 
procedures in Sec. 97.271 for each disapproved monitoring system.

Sec. 97.284  Opt-in process.

    The permitting authority will issue or deny a CAIR opt-in permit for 
a unit for which an initial application for a CAIR opt-in permit under 
Sec. 97.183 is submitted in accordance with the following, to the 
extent provided in a State implementation plan revision submitted in 
accordance with Sec. 51.124(r)(1), (2), or (3) of this chapter and 
approved by the Administrator:
    (a) Interim review of monitoring plan. The permitting authority and 
the Administrator will determine, on an interim basis, the sufficiency 
of the monitoring plan accompanying the initial application for a CAIR 
opt-in permit under Sec. 97.283. A monitoring plan is sufficient, for 
purposes of interim review, if the plan appears to contain information 
demonstrating that the SO2 emissions rate and heat input of 
the unit and all other applicable parameters are monitored and reported 
in accordance with subpart HHH of this part. A determination of 
sufficiency shall not be construed as acceptance or approval of the 
monitoring plan.
    (b) Monitoring and reporting. (1)(i) If the permitting authority and 
the Administrator determine that the monitoring plan is sufficient under 
paragraph (a) of this section, the owner or operator shall monitor and 
report the SO2 emissions rate and the heat input of the unit 
and all other applicable parameters, in accordance with subpart HHH of 
this part, starting on the date of certification of the appropriate 
monitoring systems under subpart HHH of this part and continuing until a 
CAIR opt-in permit is denied under Sec. 97.284(f) or, if a CAIR opt-in 
permit is issued, the date and time when the unit is withdrawn from the 
CAIR SO2 Trading Program in accordance with Sec. 97.286.
    (ii) The monitoring and reporting under paragraph (b)(1)(i) of this 
section shall include the entire control period

[[Page 147]]

immediately before the date on which the unit enters the CAIR 
SO2 Trading Program under Sec. 97.284(g), during which 
period monitoring system availability must not be less than 90 percent 
under subpart HHH of this part and the unit must be in full compliance 
with any applicable State or Federal emissions or emissions-related 
requirements.
    (2) To the extent the SO2 emissions rate and the heat 
input of the unit are monitored and reported in accordance with subpart 
HHH of this part for one or more control periods, in addition to the 
control period under paragraph (b)(1)(ii) of this section, during which 
control periods monitoring system availability is not less than 90 
percent under subpart HHH of this part and the unit is in full 
compliance with any applicable State or Federal emissions or emissions-
related requirements and which control periods begin not more than 3 
years before the unit enters the CAIR SO2 Trading Program 
under Sec. 97.284(g), such information shall be used as provided in 
paragraphs (c) and (d) of this section.
    (c) Baseline heat input. The unit's baseline heat input shall equal:
    (1) If the unit's SO2 emissions rate and heat input are 
monitored and reported for only one control period, in accordance with 
paragraph (b)(1) of this section, the unit's total heat input (in mmBtu) 
for the control period; or
    (2) If the unit's SO2 emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, the average of the 
amounts of the unit's total heat input (in mmBtu) for the control 
periods under paragraphs (b)(1)(ii) and (2) of this section.
    (d) Baseline SO2 emission rate. The unit's baseline SO2 
emission rate shall equal:
    (1) If the unit's SO2 emissions rate and heat input are 
monitored and reported for only one control period, in accordance with 
paragraph (b)(1) of this section, the unit's SO2 emissions 
rate (in lb/mmBtu) for the control period;
    (2) If the unit's SO2 emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, and the unit does not 
have add-on SO2 emission controls during any such control 
periods, the average of the amounts of the unit's SO2 
emissions rate (in lb/mmBtu) for the control periods under paragraphs 
(b)(1)(ii) and (2) of this section; or
    (3) If the unit's SO2 emissions rate and heat input are 
monitored and reported for more than one control period, in accordance 
with paragraphs (b)(1) and (2) of this section, and the unit has add-on 
SO2 emission controls during any such control periods, the 
average of the amounts of the unit's SO2 emissions rate (in 
lb/mmBtu) for such control periods during which the unit has add-on 
SO2 emission controls.
    (e) Issuance of CAIR opt-in permit. After calculating the baseline 
heat input and the baseline SO2 emissions rate for the unit 
under paragraphs (c) and (d) of this section and if the permitting 
authority determines that the CAIR designated representative shows that 
the unit meets the requirements for a CAIR SO2 opt-in unit in 
Sec. 97.280 and meets the elements certified in Sec. 97.283(a)(2), the 
permitting authority will issue a CAIR opt-in permit. The permitting 
authority will provide a copy of the CAIR opt-in permit to the 
Administrator, who will then establish a compliance account for the 
source that includes the CAIR SO2 opt-in unit unless the 
source already has a compliance account.
    (f) Issuance of denial of CAIR opt-in permit. Notwithstanding 
paragraphs (a) through (e) of this section, if at any time before 
issuance of a CAIR opt-in permit for the unit, the permitting authority 
determines that the CAIR designated representative fails to show that 
the unit meets the requirements for a CAIR SO2 opt-in unit in 
Sec. 97.280 or meets the elements certified in Sec. 97.283(a)(2), the 
permitting authority will issue a denial of a CAIR opt-in permit for the 
unit.
    (g) Date of entry into CAIR SO2 Trading Program. A unit for which an 
initial CAIR opt-in permit is issued by the permitting authority shall 
become a CAIR SO2 opt-in unit, and a CAIR SO2 
unit, as of the later of January 1, 2010 or January 1 of the first 
control period

[[Page 148]]

during which such CAIR opt-in permit is issued.
    (h) Repowered CAIR SO2 opt-in unit. (1) If CAIR designated 
representative requests, and the permitting authority issues a CAIR opt-
in permit providing for, allocation to a CAIR SO2 opt-in unit 
of CAIR SO2 allowances under Sec. 97.288(c) and such unit is 
repowered after its date of entry into the CAIR SO2 Trading 
Program under paragraph (g) of this section, the repowered unit shall be 
treated as a CAIR SO2 opt-in unit replacing the original CAIR 
SO2 opt-in unit, as of the date of start-up of the repowered 
unit's combustion chamber.
    (2) Notwithstanding paragraphs (c) and (d) of this section, as of 
the date of start-up under paragraph (h)(1) of this section, the 
repowered unit shall be deemed to have the same date of commencement of 
operation, date of commencement of commercial operation, baseline heat 
input, and baseline SO2 emission rate as the original CAIR 
SO2 opt-in unit, and the original CAIR SO2 opt-in 
unit shall no longer be treated as a CAIR SO2 opt-in unit or 
a CAIR SO2 unit.

operators of the unit must comply with, the requirements of Sec. 
97.287.
    (b) Each CAIR opt-in permit is deemed to incorporate automatically 
the definitions of terms under Sec. 97.202 and, upon recordation by the 
Administrator under subpart FFF or GGG of this part or this subpart, 
every allocation, transfer, or deduction of CAIR SO2 
allowances to or from the compliance account of the source that includes 
a CAIR SO2 opt-in unit covered by the CAIR opt-in permit.
    (c) The CAIR opt-in permit shall be included, in a format specified 
by the permitting authority, in the CAIR permit for the source where the 
CAIR SO2 opt-in unit is located and in a title V operating 
permit or other federally enforceable permit for the source.



Sec. 97.286  Withdrawal from CAIR SO2 Trading Program.

    Except as provided under paragraph (g) of this section, a CAIR 
SO2 opt-in unit may withdraw from the CAIR SO2 
Trading Program, but only if the permitting authority issues a 
notification to the CAIR designated representative of the CAIR 
SO2 opt-in unit of the acceptance of the withdrawal of the 
CAIR SO2 opt-in unit in accordance with paragraph (d) of this 
section.
    (a) Requesting withdrawal. In order to withdraw a CAIR 
SO2 opt-in unit from the CAIR SO2 Trading Program, 
the CAIR designated representative of the CAIR SO2 opt-in 
unit shall submit to the permitting authority a request to withdraw 
effective as of midnight of December 31 of a specified calendar year, 
which date must be at least 4 years after December 31 of the year of 
entry into the CAIR SO2 Trading Program under Sec. 
97.284(g). The request must be submitted no later than 90 days before 
the requested effective date of withdrawal.
    (b) Conditions for withdrawal. Before a CAIR SO2 opt-in 
unit covered by a request under paragraph (a) of this section may 
withdraw from the CAIR SO2 Trading Program and the CAIR opt-
in permit may be terminated under paragraph (e) of this section, the 
following conditions must be met:
    (1) For the control period ending on the date on which the 
withdrawal is to be effective, the source that includes the CAIR 
SO2 opt-in unit must meet the requirement to hold CAIR 
SO2 allowances under Sec. 97.206(c) and cannot have any 
excess emissions.

[[Page 149]]

    (2) After the requirement for withdrawal under paragraph (b)(1) of 
this section is met, the Administrator will deduct from the compliance 
account of the source that includes the CAIR SO2 opt-in unit 
CAIR SO2 allowances equal in amount to and allocated for the 
same or a prior control period as any CAIR SO2 allowances 
allocated to the CAIR SO2 opt-in unit under Sec. 97.288 for 
any control period for which the withdrawal is to be effective. If there 
are no remaining CAIR SO2 units at the source, the 
Administrator will close the compliance account, and the owners and 
operators of the CAIR SO2 opt-in unit may submit a CAIR 
SO2 allowance transfer for any remaining CAIR SO2 
allowances to another CAIR SO2 Allowance Tracking System in 
accordance with subpart GGG of this part.
    (c) Notification. (1) After the requirements for withdrawal under 
paragraphs (a) and (b) of this section are met (including deduction of 
the full amount of CAIR SO2 allowances required), the 
permitting authority will issue a notification to the CAIR designated 
representative of the CAIR SO2 opt-in unit of the acceptance 
of the withdrawal of the CAIR SO2 opt-in unit as of midnight 
on December 31 of the calendar year for which the withdrawal was 
requested.
    (2) If the requirements for withdrawal under paragraphs (a) and (b) 
of this section are not met, the permitting authority will issue a 
notification to the CAIR designated representative of the CAIR 
SO2 opt-in unit that the CAIR SO2 opt-in unit's 
request to withdraw is denied. Such CAIR SO2 opt-in unit 
shall continue to be a CAIR SO2 opt-in unit.
    (d) Permit amendment. After the permitting authority issues a 
notification under paragraph (c)(1) of this section that the 
requirements for withdrawal have been met, the permitting authority will 
revise the CAIR permit covering the CAIR SO2 opt-in unit to 
terminate the CAIR opt-in permit for such unit as of the effective date 
specified under paragraph (c)(1) of this section. The unit shall 
continue to be a CAIR SO2 opt-in unit until the effective 
date of the termination and shall comply with all requirements under the 
CAIR SO2 Trading Program concerning any control periods for 
which the unit is a CAIR SO2 opt-in unit, even if such 
requirements arise or must be complied with after the withdrawal takes 
effect.
    (e) Reapplication upon failure to meet conditions of withdrawal. If 
the permitting authority denies the CAIR SO2 opt-in unit's 
request to withdraw, the CAIR designated representative may submit 
another request to withdraw in accordance with paragraphs (a) and (b) of 
this section.
    (f) Ability to reapply to the CAIR SO2 Trading Program. Once a CAIR 
SO2 opt-in unit withdraws from the CAIR SO2 
Trading Program and its CAIR opt-in permit is terminated under this 
section, the CAIR designated representative may not submit another 
application for a CAIR opt-in permit under Sec. 97.283 for such CAIR 
SO2 opt-in unit before the date that is 4 years after the 
date on which the withdrawal became effective. Such new application for 
a CAIR opt-in permit will be treated as an initial application for a 
CAIR opt-in permit under Sec. 97.284.
    (g) Inability to withdraw. Notwithstanding paragraphs (a) through 
(f) of this section, a CAIR SO2 opt-in unit shall not be 
eligible to withdraw from the CAIR SO2 Trading Program if the 
CAIR designated representative of the CAIR SO2 opt-in unit 
requests, and the permitting authority issues a CAIR opt-in permit 
providing for, allocation to the CAIR SO2 opt-in unit of CAIR 
SO2 allowances under Sec. 97.288(c).



Sec. 97.287  Change in regulatory status.

    (a) Notification. If a CAIR SO2 opt-in unit becomes a 
CAIR SO2 unit under Sec. 97.204, then the CAIR designated 
representative shall notify in writing the permitting authority and the 
Administrator of such change in the CAIR SO2 opt-in unit's 
regulatory status, within 30 days of such change.
    (b) Permitting authority's and Administrator's actions. (1) If a 
CAIR SO2 opt-in unit becomes a CAIR SO2 unit under 
Sec. 97.204, the permitting authority will revise the CAIR 
SO2 opt-in unit's CAIR opt-in permit to meet the requirements 
of a CAIR permit under Sec. 97.223, and remove the CAIR opt-in permit 
provisions, as of the date on which the CAIR SO2 opt-in unit 
becomes a CAIR SO2 unit under Sec. 97.204.

[[Page 150]]

    (2)(i) The Administrator will deduct from the compliance account of 
the source that includes the CAIR SO2 opt-in unit that 
becomes a CAIR SO2 unit under Sec. 97.204, CAIR 
SO2 allowances equal in amount to and allocated for the same 
or a prior control period as:
    (A) Any CAIR SO2 allowances allocated to the CAIR 
SO2 opt-in unit under Sec. 97.288 for any control period 
after the date on which the CAIR SO2 opt-in unit becomes a 
CAIR SO2 unit under Sec. 97.204; and
    (B) If the date on which the CAIR SO2 opt-in unit becomes 
a CAIR SO2 unit under Sec. 97.204 is not December 31, the 
CAIR SO2 allowances allocated to the CAIR SO2 opt-
in unit under Sec. 97.288 for the control period that includes the date 
on which the CAIR SO2 opt-in unit becomes a CAIR 
SO2 unit under Sec. 97.204, multiplied by the ratio of the 
number of days, in the control period, starting with the date on which 
the CAIR SO2 opt-in unit becomes a CAIR SO2 unit 
under Sec. 97.204 divided by the total number of days in the control 
period and rounded to the nearest whole allowance as appropriate.
    (ii) The CAIR designated representative shall ensure that the 
compliance account of the source that includes the CAIR SO2 
opt-in unit that becomes a CAIR SO2 unit under Sec. 97.204 
contains the CAIR SO2 allowances necessary for completion of 
the deduction under paragraph (b)(2)(i) of this section.

Sec. 97.288  CAIR SO2 allowance allocations to CAIR SO2 opt-in units.

    (a) Timing requirements. (1) When the CAIR opt-in permit is issued 
under Sec. 97.284(e), the permitting authority will allocate CAIR 
SO2 allowances to the CAIR SO2 opt-in unit, and 
submit to the Administrator the allocation for the control period in 
which a CAIR SO2 opt-in unit enters the CAIR SO2 
Trading Program under Sec. 97.284(g), in accordance with paragraph (b) 
or (c) of this section.
    (2) By no later than October 31 of the control period after the 
control period in which a CAIR SO2 opt-in unit enters the 
CAIR SO2 Trading Program under Sec. 97.284(g) and October 31 
of each year thereafter, the permitting authority will allocate CAIR 
SO2 allowances to the CAIR SO2 opt-in unit, and 
submit to the Administrator the allocation for the control period that 
includes such submission deadline and in which the unit is a CAIR 
SO2 opt-in unit, in accordance with paragraph (b) or (c) of 
this section.
    (b) Calculation of allocation. For each control period for which a 
CAIR SO2 opt-in unit is to be allocated CAIR SO2 
allowances, the permitting authority will allocate in accordance with 
the following procedures, if provided in a State implementation plan 
revision submitted in accordance with Sec. 51.124(r)(1), (2), or (3) of 
this chapter and approved by the Administrator:
    (1) The heat input (in mmBtu) used for calculating the CAIR 
SO2 allowance allocation will be the lesser of:
    (i) The CAIR SO2 opt-in unit's baseline heat input 
determined under Sec. 97.284(c); or
    (ii) The CAIR SO2 opt-in unit's heat input, as determined 
in accordance with subpart HHH of this part, for the immediately prior 
control period, except when the allocation is being calculated for the 
control period in which the CAIR SO2 opt-in unit enters the 
CAIR SO2 Trading Program under Sec. 97.284(g).
    (2) The SO2 emission rate (in lb/mmBtu) used for 
calculating CAIR SO2 allowance allocations will be the lesser 
of:
    (i) The CAIR SO2 opt-in unit's baseline SO2 
emissions rate (in lb/mmBtu) determined under Sec. 97.284(d) and 
multiplied by 70 percent; or
    (ii) The most stringent State or Federal SO2 emissions 
limitation applicable to the CAIR SO2 opt-in unit at any time 
during the control period for which CAIR SO2 allowances are 
to be allocated.
    (3) The permitting authority will allocate CAIR SO2 
allowances to the CAIR SO2 opt-in unit with a tonnage 
equivalent equal to, or less than by the smallest possible amount, the 
heat input under paragraph (b)(1) of this section, multiplied by the 
SO2 emission rate under paragraph (b)(2) of this section, and 
divided by 2,000 lb/ton.
    (c) Notwithstanding paragraph (b) of this section and if the CAIR 
designated

[[Page 151]]

representative requests, and the permitting authority issues a CAIR opt-
in permit (based on a demonstration of the intent to repower stated 
under Sec. 97.283(a)(5)) providing for, allocation to a CAIR 
SO2 opt-in unit of CAIR SO2 allowances under this 
paragraph (subject to the conditions in Sec. Sec. 97.284(h) and 
97.286(g)), the permitting authority will allocate to the CAIR 
SO2 opt-in unit as follows, if provided in a State 
implementation plan revision submitted in accordance with Sec. 
51.124(r)(1), (2), or (3) of this chapter and approved by the 
Administrator:
    (1) For each control period in 2010 through 2014 for which the CAIR 
SO2 opt-in unit is to be allocated CAIR SO2 
allowances,
    (i) The heat input (in mmBtu) used for calculating CAIR 
SO2 allowance allocations will be determined as described in

Sec. 97.342  CAIR NOX Ozone Season allowance allocations.

    (a)(1) The baseline heat input (in mmBtu) used with respect to CAIR 
NOX Ozone Season allowance allocations under paragraph (b) of 
this section for each CAIR NOX Ozone Season unit will be:
    (i) For units commencing operation before January 1, 2001 the 
average of the 3 highest amounts of the unit's adjusted control period 
heat input for 2000 through 2004, with the adjusted control period heat 
input for each year calculated as follows:
    (A) If the unit is coal-fired during the year, the unit's control 
period heat input for such year is multiplied by 100 percent;
    (B) If the unit is oil-fired during the year, the unit's control 
period heat input for such year is multiplied by 60 percent; and
    (C) If the unit is not subject to paragraph (a)(1)(i)(A) or (B) of 
this section, the unit's control period heat input for such year is 
multiplied by 40 percent.
    (ii) For units commencing operation on or after January 1, 2001 and 
operating each calendar year during a period of 5 or more consecutive 
calendar years, the average of the 3 highest amounts of the unit's total 
converted control period heat input over the first such 5 years.
    (2)(i) A unit's control period heat input, and a unit's status as 
coal-fired or oil-fired, for a calendar year under paragraph (a)(1)(i) 
of this section, and a unit's total tons of NOX emissions 
during a control period in a calendar year under paragraph (c)(3) of 
this section, will be determined in accordance with part 75 of this 
chapter, to the extent the unit was otherwise subject to the 
requirements of part 75 of this chapter for the year, or will be based 
on the best available data reported to the Administrator for the unit 
(in a format prescribed by the Administrator), to the extent the unit 
was not otherwise subject to the requirements of part 75 of this chapter 
for the year.
    (ii) A unit's converted control period heat input for a calendar 
year specified under paragraph (a)(1)(ii) of this section equals:
    (A) Except as provided in paragraph (a)(2)(ii)(B) or (C) of this 
section, the control period gross electrical output of the generator or 
generators served by the unit multiplied by 7,900 Btu/kWh, if the unit 
is coal-fired for the year, or 6,675 Btu/kWh, if the unit is not coal-
fired for the year, and divided by 1,000,000 Btu/mmBtu, provided that if 
a generator is served by 2 or more units, then the gross electrical 
output of the generator will be attributed to each unit in proportion to 
the unit's share of the total control period heat input of such units 
for the year;
    (B) For a unit that is a boiler and has equipment used to produce 
electricity and useful thermal energy for industrial, commercial, 
heating, or cooling purposes through the sequential use of energy, the 
total heat energy (in Btu) of the steam produced by the boiler during 
the control period, divided by 0.8 and by 1,000,000 Btu/mmBtu; or
    (C) For a unit that is a combustion turbine and has equipment used 
to produce electricity and useful thermal energy for industrial, 
commercial, heating, or cooling purposes through the sequential use of 
energy, the control period gross electrical output of the enclosed 
device comprising the compressor, combustor, and turbine multiplied by 
3,413 Btu/kWh, plus the total heat energy (in Btu) of the steam produced 
by any associated heat recovery steam generator during the control 
period divided by 0.8, and with the sum divided by 1,000,000 Btu/mmBtu.

[[Page 173]]

    (iii) Gross electrical output and total heat energy under paragraph 
(a)(2)(ii) of this section will be determined based on the best 
available data reported to the Administrator for the unit (in a format 
prescribed by the Administrator).
    (3) The Administrator will determine what data are the best 
available data under paragraph (a)(2) of this section by weighing the 
likelihood that data are accurate and reliable and giving greater weight 
to data submitted to a governmental entity in compliance with legal 
requirements or substantiated by an independent entity.
    (b)(1) For each control period in 2009 and thereafter, the 
Administrator will allocate to all CAIR NOX Ozone Season 
units in a State that have a baseline heat input (as determined under 
paragraph (a) of this section) a total amount of CAIR NOX 
Ozone Season allowances equal to 95 percent for a control period during 
2009 through 2014, and 97 percent for a control period during 2015 and 
thereafter, of the tons of NOX emissions in the applicable 
State trading budget under Sec. 97.340 (except as provided in 
paragraphs (d) and (e) of this section).
    (2) The Administrator will allocate CAIR NOX Ozone Season 
allowances to each CAIR NOX Ozone Season unit under paragraph 
(b)(1) of this section in an amount determined by multiplying the total 
amount of CAIR NOX Ozone Season allowances allocated under 
paragraph (b)(1) of this section by the ratio of the baseline heat input 
of such CAIR NOX Ozone Season unit to the total amount of 
baseline heat input of all such CAIR NOX Ozone Season units 
in the State and rounding to the nearest whole allowance as appropriate.
    (c) For each control period in 2009 and thereafter, the 
Administrator will allocate CAIR NOX Ozone Season allowances 
to CAIR NOX Ozone Season units in a State that are not 
allocated CAIR NOX Ozone Season allowances under paragraph 
(b) of this section because the units do not yet have a baseline heat 
input under paragraph (a) of this section or because the units have a 
baseline heat input but all CAIR NOX Ozone Season allowances 
available under paragraph (b) of this section for the control period are 
already allocated, in accordance with the following procedures:
    (1) The Administrator will establish a separate new unit set-aside 
for each control period. Each new unit set-aside will be allocated CAIR 
NOX Ozone Season allowances equal to 5 percent for a control 
period in 2009 through 2014, and 3 percent for a control period in 2015 
and thereafter, of the amount of tons of NOX emissions in the 
applicable State trading budget under Sec. 97.340.
    (2) The CAIR designated representative of such a CAIR NOX 
Ozone Season unit may submit to the Administrator a request, in a format 
specified by the Administrator, to be allocated CAIR NOX 
Ozone Season allowances, starting with the later of the control period 
in 2009 or the first control period after the control period in which 
the CAIR NOX Ozone Season unit commences commercial operation 
and until the first control period for which the unit is allocated CAIR 
NOX Ozone Season allowances under paragraph (b) of this 
section. A separate CAIR NOX Ozone Season allowance 
allocation request for each control period for which CAIR NOX 
Ozone Season allowances are sought must be submitted on or before 
February 1 before such control period and after the date on which the 
CAIR NOX Ozone Season unit commences commercial operation.
    (3) In a CAIR NOX Ozone Season allowance allocation 
request under paragraph (c)(2) of this section, the CAIR designated 
representative may request for a control period CAIR NOX 
Ozone Season allowances in an amount not exceeding the CAIR 
NOX Ozone Season unit(s total tons of NOX 
emissions during the control period immediately before such control 
period.
    (4) The Administrator will review each CAIR NOX Ozone 
Season allowance allocation request under paragraph (c)(2) of this 
section and will allocate CAIR NOX Ozone Season allowances 
for each control period pursuant to such request as follows:
    (i) The Administrator will accept an allowance allocation request 
only if the request meets, or is adjusted by the Administrator as 
necessary to meet, the requirements of paragraphs (c)(2) and (3) of this 
section.

[[Page 174]]

    (ii) On or after February 1 before the control period, the 
Administrator will determine the sum of the CAIR NOX Ozone 
Season allowances requested (as adjusted under paragraph (c)(4)(i) of 
this section) in all allowance allocation requests accepted under 
paragraph (c)(4)(i) of this section for the control period.
    (iii) If the amount of CAIR NOX Ozone Season allowances 
in the new unit set-aside for the control period is greater than or 
equal to the sum under paragraph (c)(4)(ii) of this section, then the 
Administrator will allocate the amount of CAIR NOX Ozone 
Season allowances requested (as adjusted under paragraph (c)(4)(i) of 
this section) to each CAIR NOX Ozone Season unit covered by 
an allowance allocation request accepted under paragraph (c)(4)(i) of 
this section.
    (iv) If the amount of CAIR NOX Ozone Season allowances in 
the new unit set-aside for the control period is less than the sum under 
paragraph (c)(4)(ii) of this section, then the Administrator will 
allocate to each CAIR NOX Ozone Season unit covered by an 
allowance allocation request accepted under paragraph (c)(4)(i) of this 
section the amount of the CAIR NOX Ozone Season allowances 
requested (as adjusted under paragraph (c)(4)(i) of this section), 
multiplied by the amount of CAIR NOX Ozone Season allowances 
in the new unit set-aside for the control period, divided by the sum 
determined under paragraph (c)(4)(ii) of this section, and rounded to 
the nearest whole allowance as appropriate.
    (v) The Administrator will notify each CAIR designated 
representative that submitted an allowance allocation request of the 
amount of CAIR NOX Ozone Season allowances (if any) allocated 
for the control period to the CAIR NOX Ozone Season unit 
covered by the request.
    (d) If, after completion of the procedures under paragraph (c)(4) of 
this section for a control period, any unallocated CAIR NOX 
Ozone Season allowances remain in the new unit set-aside under paragraph 
(c) of this section for a State for the control period, the 
Administrator will allocate to each CAIR NOX Ozone Season 
unit that was allocated CAIR NOX Ozone Season allowances 
under paragraph (b) of this section in the State an amount of CAIR 
NOX Ozone Season allowances equal to the total amount of such 
remaining unallocated CAIR NOX Ozone Season allowances, 
multiplied by the unit's allocation under paragraph (b) of this section, 
divided by 95 percent for a control period during 2009 through 2014, and 
97 percent for a control period during 2015 and thereafter, of the 
amount of tons of NOX emissions in the applicable State 
trading budget under Sec. 97.340, and rounded to the nearest whole 
allowance as appropriate.
    (e) If the Administrator determines that CAIR NOX Ozone 
Season allowances were allocated under paragraphs (a) and (b) of this 
section, paragraphs (a) and (c) of this section, or paragraph (d) of 
this section for a control period and that the recipient of the 
allocation is not actually a CAIR NOX Ozone Season unit under 
Sec. 97.304 in such control period, then the Administrator will notify 
the CAIR designated representative and will act in accordance with the 
following procedures:
    (1) Except as provided in paragraph (e)(2) or (3) of this section, 
the Administrator will not record such CAIR NOX Ozone Season 
allowances under Sec. 97.353.
    (2) If the Administrator already recorded such CAIR NOX 
Ozone Season allowances under Sec. 97.353 and if the Administrator 
makes such determinations before making deductions for the source that 
includes such recipient under Sec. 97.354(b) for the control period, 
then the Administrator will deduct from the account in which such CAIR 
NOX Ozone Season allowances were recorded under Sec. 97.353 
an amount of CAIR NOX Ozone Season allowances allocated for 
the same or a prior control period equal to the amount of such already 
recorded CAIR NOX Ozone Season allowances. The CAIR 
designated representative shall ensure that there are sufficient CAIR 
NOX Ozone Season allowances in such account for completion of 
the deduction.
    (3) If the Administrator already recorded such CAIR NOX 
Ozone Season allowances under Sec. 97.353 and if the Administrator 
makes such determinations after making deductions for the source that 
includes such recipient under Sec. 97.354(b) for the control period,

[[Page 175]]

then the Administrator will apply paragraph (e)(1) or (2) of this 
section, as appropriate, to any subsequent control period for which CAIR 
NOX Ozone Season allowances were allocated to such recipient.
    (4) The Administrator will transfer the CAIR NOX Ozone 
Season allowances that are not recorded, or that are deducted, in 
accordance with paragraphs (e)(1), (2), and (3) of this section to a new 
unit set-aside for the State in which such recipient is located.



Sec. 97.343  Alternative of allocation of CAIR NOX Ozone Season allowances by permitting authority.

    (a) Notwithstanding Sec. Sec. 97.341, 97.342, and 97.353 if a State 
submits, and the Administrator approves, a State implementation plan 
revision in accordance with Sec. 51.123(ee)(2) of this chapter 
providing for allocation of CAIR NOX Ozone Season allowances 
by the permitting authority, then the permitting authority shall make 
such allocations in accordance with such approved State implementation 
plan revision, the Administrator will not make allocations under 
Sec. Sec. 97.341 and 97.342 for the CAIR NOX Ozone Season 
units in the State, and under Sec. 97.353, the Administrator will 
record allocations made under such approved State implementation plan 
revision instead of allocations under Sec. Sec. 97.341 and 97.342.
    (b) In implementing paragraph (a) of this section and Sec. Sec. 
97.341, 97.342, and 97.353, the Administrator will ensure that the total 
amount of CAIR NOX Ozone Season allowances allocated, under 
such provisions and under a State's State implementation plan revision 
approved in accordance with Sec. 51.123(ee)(2) of this chapter, for a 
control period for CAIR NOX Ozone Season sources in the State 
or for other entities specified by the permitting authority will not 
exceed the State's State trading budget for the year of the control 
period.

is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the CAIR designated 
representative must submit the additional information required to 
complete the certification application. If the CAIR designated 
representative does not comply with the notice of incompleteness by the 
specified date, then the Administrator may issue a notice of disapproval 
under paragraph (d)(3)(iv)(C) of this section. The 120-day review period 
shall not begin before receipt of a complete certification application.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour

[[Page 186]]

the CAIR NOX Ozone Season opt-in unit of the acceptance of 
the withdrawal of the CAIR NOX Ozone Season opt-in unit in 
accordance with paragraph (d) of this section.
    (a) Requesting withdrawal. In order to withdraw a CAIR 
NOX Ozone Season opt-in unit from the CAIR NOX 
Ozone Season Trading Program, the CAIR designated representative of the 
CAIR NOX Ozone Season opt-in unit shall submit to the 
permitting authority a request to withdraw effective as of midnight of 
September 30 of a specified calendar year, which date must be at least 4 
years after September 30 of the year of entry into the CAIR 
NOX Ozone Season Trading Program under Sec. 97.384(g). The 
request must be submitted no later than 90 days before the requested 
effective date of withdrawal.
    (b) Conditions for withdrawal. Before a CAIR NOX Ozone 
Season opt-in unit covered by a request under paragraph (a) of this 
section may withdraw from the CAIR NOX Ozone Season Trading 
Program and the CAIR opt-in permit may be terminated under paragraph (e) 
of this section, the following conditions must be met:
    (1) For the control period ending on the date on which the 
withdrawal is to be effective, the source that includes the CAIR 
NOX Ozone Season opt-in unit must meet the requirement to 
hold CAIR NOX Ozone Season allowances under Sec. 97.306(c) 
and cannot have any excess emissions.
    (2) After the requirement for withdrawal under paragraph (b)(1) of 
this section is met, the Administrator will deduct from the compliance 
account of the source that includes the CAIR NOX Ozone Season 
opt-in unit CAIR NOX

[[Page 193]]

Ozone Season allowances equal in amount to and allocated for the same or 
a prior control period as any CAIR NOX Ozone Season 
allowances allocated to the CAIR NOX Ozone Season opt-in unit 
under Sec. 97.388 for any control period for which the withdrawal is to 
be effective. If there are no remaining CAIR NOX Ozone Season 
units at the source, the Administrator will close the compliance 
account, and the owners and operators of the CAIR NOX Ozone 
Season opt-in unit may submit a CAIR NOX Ozone Season 
allowance transfer for any remaining CAIR NOX Ozone Season 
allowances to another CAIR NOX Ozone Season Allowance 
Tracking System in accordance with subpart GGGG of this part.
    (c) Notification. (1) After the requirements for withdrawal under 
paragraphs (a) and (b) of this section are met (including deduction of 
the full amount of CAIR NOX Ozone Season allowances 
required), the permitting authority will issue a notification to the 
CAIR designated representative of the CAIR NOX Ozone Season 
opt-in unit of the acceptance of the withdrawal of the CAIR 
NOX Ozone Season opt-in unit as of midnight on September 30 
of the calendar year for which the withdrawal was requested.
    (2) If the requirements for withdrawal under paragraphs (a) and (b) 
of this section are not met, the permitting authority will issue a 
notification to the CAIR designated representative of the CAIR 
NOX Ozone Season opt-in unit that the CAIR NOX 
Ozone Season opt-in unit's request to withdraw is denied. Such CAIR 
NOX Ozone Season opt-in unit shall continue to be a CAIR 
NOX Ozone Season opt-in unit.
    (d) Permit amendment. After the permitting authority issues a 
notification under paragraph (c)(1) of this section that the 
requirements for withdrawal have been met, the permitting authority will 
revise the CAIR permit covering the CAIR NOX Ozone Season 
opt-in unit to terminate the CAIR opt-in permit for such unit as of the 
effective date specified under paragraph (c)(1) of this section. The 
unit shall continue to be a CAIR NOX Ozone Season opt-in unit 
until the effective date of the termination and shall comply with all 
requirements under the CAIR NOX Ozone Season Trading Program 
concerning any control periods for which the unit is a CAIR 
NOX Ozone Season opt-in unit, even if such requirements arise 
or must be complied with after the withdrawal takes effect.
    (e) Reapplication upon failure to meet conditions of withdrawal. If 
the permitting authority denies the CAIR NOX Ozone Season 
opt-in unit's request to withdraw, the CAIR designated representative 
may submit another request to withdraw in accordance with paragraphs (a) 
and (b) of this section.
    (f) Ability to reapply to the CAIR NOX Ozone Season Trading Program. 
Once a CAIR NOX Ozone Season opt-in unit withdraws from the 
CAIR NOX Ozone Season Trading Program and its CAIR opt-in 
permit is terminated under this section, the CAIR designated 
representative may not submit another application for a CAIR opt-in 
permit under Sec. 97.383 for such CAIR NOX Ozone Season opt-
in unit before the date that is 4 years after the date on which the 
withdrawal became effective. Such new application for a CAIR opt-in 
permit will be treated as an initial application for a CAIR opt-in 
permit under Sec. 97.384.
    (g) Inability to withdraw. Notwithstanding paragraphs (a) through 
(f) of this section, a CAIR NOX Ozone Season opt-in unit 
shall not be eligible to withdraw from the CAIR NOX Ozone 
Season Trading Program if the CAIR designated representative of the CAIR 
NOX Ozone Season opt-in unit requests, and the permitting 
authority issues a CAIR opt-in permit providing for, allocation to the 
CAIR NOX Ozone Season opt-in unit of CAIR NOX 
Ozone Season allowances under Sec. 97.388(c).



Sec. 97.387  Change in regulatory status.

    (a) Notification. If a CAIR NOX Ozone Season opt-in unit 
becomes a CAIR NOX Ozone Season unit under Sec. 97.304, then 
the CAIR designated representative shall notify in writing the 
permitting authority and the Administrator of such change in the CAIR 
NOX Ozone Season opt-in unit's regulatory status, within 30 
days of such change.
    (b) Permitting authority's and Administrator's actions. (1) If a 
CAIR NOX Ozone Season opt-in unit becomes a CAIR 
NOX Ozone Season unit under Sec. 97.304, the permitting 
authority will revise

[[Page 194]]

the CAIR NOX Ozone Season opt-in unit's CAIR opt-in permit to 
meet the requirements of a CAIR permit under Sec. 97.323, and remove 
the CAIR opt-in permit provisions, as of the date on which the CAIR 
NOX Ozone Season opt-in unit becomes a CAIR NOX 
Ozone Season unit under Sec. 97.304.
    (2)(i) The Administrator will deduct from the compliance account of 
the source that includes the CAIR NOX Ozone Season opt-in 
unit that becomes a CAIR NOX Ozone Season unit under Sec. 
97.304, CAIR NOX Ozone Season allowances equal in amount to 
and allocated for the same or a prior control period as:

CAIR NOX Ozone Season opt-in unit under Sec. 97.388 for any 
control period after the date on which the CAIR NOX Ozone 
Season opt-in unit becomes a CAIR NOX Ozone Season unit under 
Sec. 97.304; and
    (B) If the date on which the CAIR NOX Ozone Season opt-in 
unit becomes a CAIR NOX Ozone Season unit under Sec. 97.304 
is not September 30, the CAIR NOX Ozone Season allowances 
allocated to the CAIR NOX Ozone Season opt-in unit under 
Sec. 97.388 for the control period that includes the date on which the 
CAIR NOX Ozone Season opt-in unit becomes a CAIR 
NOX Ozone Season unit under Sec. 97.304, multiplied by the 
ratio of the number of days, in the control period, starting with the 
date on which the CAIR NOX Ozone Season opt-in unit becomes a 
CAIR NOX Ozone Season unit under Sec. 97.304 divided by the 
total number of days in the control period and rounded to the nearest 
whole allowance as appropriate.
    (ii) The CAIR designated representative shall ensure that the 
compliance account of the source that includes the CAIR NOX 
Ozone Season opt-in unit that becomes a CAIR NOX Ozone Season 
unit under Sec. 97.304 contains the CAIR NOX Ozone Season 
allowances necessary for completion of the deduction under paragraph 
(b)(2)(i) of this section.
    (3)(i) For every control period after the date on which the CAIR 
NOX Ozone Season opt-in unit becomes a CAIR NOX 
Ozone Season unit under Sec. 97.304, the CAIR NOX Ozone 
Season opt-in unit will be allocated CAIR NOX Ozone Season 
allowances under Sec. 97.342.
    (ii) If the date on which the CAIR NOX Ozone Season opt-
in unit becomes a CAIR NOX Ozone Season unit under Sec. 
97.304 is not September 30, the following amount of CAIR NOX 
Ozone Season allowances will be allocated to the CAIR NOX 
Ozone Season opt-in unit (as a CAIR NOX Ozone Season unit) 
under Sec. 97.342 for the control period that includes the date on 
which the CAIR NOX Ozone Season opt-in unit becomes a CAIR 
NOX Ozone Season unit under Sec. 97.304:
    (A) The amount of CAIR NOX Ozone Season allowances 
otherwise allocated to the CAIR NOX Ozone Season opt-in unit 
(as a CAIR NOX Ozone Season unit) under Sec. 97.342 for the 
control period multiplied by;
    (B) The ratio of the number of days, in the control period, starting 
with the date on which the CAIR NOX Ozone Season opt-in unit 
becomes a CAIR NOX Ozone Season unit under Sec. 97.304,

Sec. 97.406  Standard requirements.

    (a) Designated representative requirements. The owners and operators 
shall comply with the requirement to have a designated representative, 
and may have an alternate designated representative, in accordance with 
Sec. Sec. 97.413 through 97.418.
    (b) Emissions monitoring, reporting, and recordkeeping requirements. 
(1) The owners and operators, and the designated representative, of each 
CSAPR NOX Annual source and each CSAPR NOX Annual 
unit at the source shall comply with the monitoring, reporting, and 
recordkeeping requirements of Sec. Sec. 97.430 through 97.435.
    (2) The emissions data determined in accordance with Sec. Sec. 
97.430 through 97.435 shall be used to calculate allocations of CSAPR 
NOX Annual allowances under Sec. Sec. 97.411(a)(2) and (b) 
and 97.412 and to determine compliance with the CSAPR NOX 
Annual emissions limitation and assurance provisions under paragraph (c) 
of this section, provided that, for each monitoring location from which 
mass emissions are reported, the mass emissions amount used in 
calculating such allocations and determining such compliance shall be 
the mass emissions amount for the monitoring location determined in 
accordance with Sec. Sec. 97.430 through 97.435 and rounded to the 
nearest ton, with any fraction of a ton less than 0.50 being deemed to 
be zero.
    (c) NOX emissions requirements--(1) CSAPR NOX Annual 
emissions limitation. (i) As of the allowance transfer deadline for a 
control period in a given year, the owners and operators of each CSAPR 
NOX Annual source and each CSAPR NOX Annual unit 
at the source shall hold, in the source's compliance account, CSAPR 
NOX Annual allowances available for deduction for such 
control period under Sec. 97.424(a) in an amount not less than the tons 
of total NOX emissions for such control period from all CSAPR 
NOX Annual units at the source.
    (ii) If total NOX emissions during a control period in a 
given year from the CSAPR NOX Annual units at a CSAPR 
NOX Annual source are in excess of the CSAPR NOX 
Annual emissions limitation set forth in paragraph (c)(1)(i) of this 
section, then:
    (A) The owners and operators of the source and each CSAPR 
NOX Annual unit at the source shall hold the CSAPR 
NOX Annual allowances required for deduction under Sec. 
97.424(d); and
    (B) The owners and operators of the source and each CSAPR 
NOX Annual unit at the source shall pay any fine, penalty, or 
assessment or comply with any other remedy imposed, for the same 
violations, under the Clean Air Act, and each ton of such excess 
emissions and each day of such control period shall constitute a 
separate violation of this subpart and the Clean Air Act.
    (2) CSAPR NOX Annual assurance provisions. (i) If total 
NOX emissions during a control period in a given year from 
all CSAPR NOX Annual units at CSAPR NOX Annual 
sources in a State (and Indian country within the borders of such State) 
exceed the State assurance level, then the owners and operators of such 
sources and units in each group of one or more sources and units having 
a common designated representative for such control period, where the 
common designated representative's share of such NOX 
emissions during such control period exceeds the common designated 
representative's assurance level for the State and such control period, 
shall hold (in the assurance account established for the owners and 
operators of such group) CSAPR NOX Annual allowances 
available for deduction for such control period under Sec. 97.425(a) in 
an amount equal to two times the product (rounded to the nearest whole 
number), as determined by the Administrator in accordance with Sec. 
97.425(b), of multiplying--
    (A) The quotient of the amount by which the common designated 
representative's share of such NOX emissions exceeds the 
common designated representative's assurance level divided by the sum of 
the amounts, determined for all common designated

[[Page 209]]

representatives for such sources and units in the State (and Indian 
country within the borders of such State) for such control period, by 
which each common designated representative's share of such 
NOX emissions exceeds the respective common designated 
representative's assurance level; and
    (B) The amount by which total NOX emissions from all 
CSAPR NOX Annual units at CSAPR NOX Annual sources 
in the State (and Indian country within the borders of such State) for 
such control period exceed the State assurance level.
    (ii) The owners and operators shall hold the CSAPR NOX 
Annual allowances required under paragraph (c)(2)(i) of this section, as 
of midnight of November 1 (if it is a business day), or midnight of the 
first business day thereafter (if November 1 is not a business day), 
immediately after the year of such control period.
    (iii) Total NOX emissions from all CSAPR NOX 
Annual units at CSAPR NOX Annual sources in a State (and 
Indian country within the borders of such State) during a control period 
in a given year exceed the State assurance level if such total 
NOX emissions exceed the sum, for such control period, of the 
State NOX Annual trading budget under Sec. 97.410(a) and the 
State's variability limit under Sec. 97.410(b).
    (iv) It shall not be a violation of this subpart or of the Clean Air 
Act if total NOX emissions from all CSAPR NOX 
Annual units at CSAPR NOX Annual sources in a State (and 
Indian country within the borders of such State) during a control period 
exceed the State assurance level or if a common designated 
representative's share of total NOX emissions from the CSAPR 
NOX Annual units at CSAPR NOX Annual sources in a 
State (and Indian country within the borders of such State) during a 
control period exceeds the common designated representative's assurance 
level.
    (v) To the extent the owners and operators fail to hold CSAPR 
NOX Annual allowances for a control period in a given year in 
accordance with paragraphs (c)(2)(i) through (iii) of this section,
    (A) The owners and operators shall pay any fine, penalty, or 
assessment or comply with any other remedy imposed under the Clean Air 
Act; and
    (B) Each CSAPR NOX Annual allowance that the owners and 
operators fail to hold for such control period in accordance with 
paragraphs (c)(2)(i) through (iii) of this section and each day of such 
control period shall constitute a separate violation of this subpart and 
the Clean Air Act.
    (3) Compliance periods. (i) A CSAPR NOX Annual unit shall 
be subject to the requirements under paragraph (c)(1) of this section 
for the control period starting on the later of January 1, 2015 or the 
deadline for meeting the unit's monitor certification requirements under 
Sec. 97.430(b) and for each control period thereafter.
    (ii) A CSAPR NOX Annual unit shall be subject to the 
requirements under paragraph (c)(2) of this section for the control 
period starting on the later of January 1, 2017 or the deadline for 
meeting the unit's monitor certification requirements under Sec. 
97.430(b) and for each control period thereafter.
    (4) Vintage of CSAPR NOX Annual allowances held for 
compliance. (i) A CSAPR NOX Annual allowance held for 
compliance with the requirements under paragraph (c)(1)(i) of this 
section for a control period in a given year must be a CSAPR 
NOX Annual allowance that was allocated or auctioned for such 
control period or a control period in a prior year.
    (ii) A CSAPR NOX Annual allowance held for compliance 
with the requirements under paragraphs (c)(1)(ii)(A) and (c)(2)(i) 
through (iii) of this section for a control period in a given year must 
be a CSAPR NOX Annual allowance that was allocated or 
auctioned for a control period in a prior year or the control period in 
the given year or in the immediately following year.
    (5) Allowance Management System requirements. Each CSAPR 
NOX Annual allowance shall be held in, deducted from, or 
transferred into, out of, or between Allowance Management System 
accounts in accordance with this subpart.
    (6) Limited authorization. A CSAPR NOX Annual allowance 
is a limited authorization to emit one ton of NOX during the 
control period in one year.

[[Page 210]]

Such authorization is limited in its use and duration as follows:
    (i) Such authorization shall only be used in accordance with the 
CSAPR NOX Annual Trading Program; and
    (ii) Notwithstanding any other provision of this subpart, the 
Administrator has the authority to terminate or limit the use and 
duration of such authorization to the extent the Administrator 
determines is necessary or appropriate to implement any provision of the 
Clean Air Act.
    (7) Property right. A CSAPR NOX Annual allowance does not 
constitute a property right.
    (d) Title V permit requirements. (1) No title V permit revision 
shall be required for any allocation, holding, deduction, or transfer of 
CSAPR NOX Annual allowances in accordance with this subpart.
    (2) A description of whether a unit is required to monitor and 
report NOX emissions using a continuous emission monitoring 
system (under subpart H of part 75 of this chapter), an excepted 
monitoring system (under appendices D and E to part 75 of this chapter), 
a low mass emissions excepted monitoring methodology (under Sec. 75.19 
of this chapter), or an alternative monitoring system (under subpart E 
of part 75 of this chapter) in accordance with Sec. Sec. 97.430 through 
97.435 may be added to, or changed in, a title V permit using minor 
permit modification procedures in accordance with Sec. Sec. 70.7(e)(2) 
and 71.7(e)(1) of this chapter, provided that the requirements 
applicable to the described monitoring and reporting (as added or 
changed, respectively) are already incorporated in such permit. This 
paragraph explicitly provides that the addition of, or change to, a 
unit's description as described in the prior sentence is eligible for 
minor permit modification procedures in accordance with Sec. Sec. 
70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.
    (e) Additional recordkeeping and reporting requirements. (1) Unless 
otherwise provided, the owners and operators of each CSAPR 
NOX Annual source and each CSAPR NOX Annual unit 
at the source shall keep on site at the source each of the following 
documents (in hardcopy or electronic format) for a period of 5 years 
from the date the document is created. This period may be extended for 
cause, at any time before the end of 5 years, in writing by the 
Administrator.
    (i) The certificate of representation under Sec. 97.416 for the 
designated representative for the source and each CSAPR NOX 
Annual unit at the source and all documents that demonstrate the truth 
of the statements in the certificate of representation; provided that 
the certificate and documents shall be retained on site at the source 
beyond such 5-year period until such certificate of representation and 
documents are superseded because of the submission of a new certificate 
of representation under Sec. 97.416 changing the designated 
representative.
    (ii) All emissions monitoring information, in accordance with this 
subpart.

source and each CSAPR NOX Annual unit at the source shall 
make all submissions required under the CSAPR NOX Annual 
Trading Program, except as provided in Sec. 97.418. This requirement 
does not change, create an exemption from, or otherwise affect the 
responsible official submission requirements under a title V operating 
permit program in parts 70 and 71 of this chapter.
    (f) Liability. (1) Any provision of the CSAPR NOX Annual 
Trading Program that applies to a CSAPR NOX Annual source or 
the designated representative of a CSAPR NOX Annual source 
shall also apply to the owners and operators of such source and of the

Sec. 97.411  Timing requirements for CSAPR NOX Annual allowance allocations.

    (a) Existing units. (1) CSAPR NOX Annual allowances are 
allocated, for the control periods in 2015 and each year thereafter, as 
provided in a notice of data availability issued by the Administrator. 
Providing an allocation to a unit in such notice does not constitute a 
determination that the unit is a CSAPR NOX Annual unit, and 
not providing an allocation to a unit in such notice does not constitute 
a determination that the unit is not a CSAPR NOX Annual unit.
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting after 2014, 
during the control period in two consecutive years, such unit will not 
be allocated the CSAPR NOX Annual allowances provided in such 
notice for the unit for the control periods in the fifth year after the 
first such year and in each year after that fifth year. All CSAPR 
NOX Annual allowances that would otherwise have been 
allocated to such unit will be allocated to the new unit set-aside for 
the State where such unit is located and for the respective years 
involved. If such unit resumes operation, the Administrator will 
allocate CSAPR NOX Annual allowances to the unit in 
accordance with paragraph (b) of this section.
    (b) New units--(1) New unit set-asides. (i)(A) By June 1 of each 
year from 2015 through 2020, the Administrator will calculate the CSAPR 
NOX Annual allowance allocation to each CSAPR NOX 
Annual unit in a State, in accordance with Sec. 97.412(a)(2) through 
(7) and (12) and Sec. Sec. 97.406(b)(2) and 97.430 through 97.435, for 
the control period in the year of the applicable calculation deadline 
under this paragraph and will promulgate a notice of data availability 
of the results of the calculations.
    (B) By March 1, 2022 and March 1 of each year thereafter, the 
Administrator will calculate the CSAPR NOX Annual allowance 
allocation to each CSAPR NOX Annual unit in a State, in 
accordance with Sec. 97.412(a)(2) through (7), (10), and (12) and 
Sec. Sec. 97.406(b)(2) and 97.430 through 97.435, for the control 
period in the year before the year of the applicable calculation 
deadline under this paragraph and will promulgate a notice of data 
availability of the results of the calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(1)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(1)(i) of this 
section and shall be limited to addressing whether the calculations 
(including the identification of the CSAPR NOX Annual units) 
are in accordance with the provisions referenced in paragraph 
(b)(1)(i)(A) or (B) of this section, as applicable.
    (B) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(1)(i)(A) or (B) of this section,

[[Page 215]]

as applicable. By August 1 immediately after the promulgation of each 
notice of data availability required in paragraph (b)(1)(i)(A) of this 
section, or by May 1 immediately after the promulgation of each notice 
of data availability required in paragraph (b)(1)(i)(B) of this section, 
the Administrator will promulgate a notice of data availability of the 
results of the calculations incorporating any adjustments that the 
Administrator determines to be necessary and the reasons for accepting 
or rejecting any objections submitted in accordance with paragraph 
(b)(1)(ii)(A) of this section.
    (iii) If the new unit set-aside for a control period before 2021 
contains any CSAPR NOX Annual allowances that have not been 
allocated in the applicable notice of data availability required in 
paragraph (b)(1)(ii) of this section, the Administrator will promulgate, 
by December 15 immediately after such notice, a notice of data 
availability that identifies any CSAPR NOX Annual units that 
commenced commercial operation during the period starting January 1 of 
the year before the year of such control period and ending November 30 
of the year of such control period.
    (iv) For each notice of data availability required in paragraph 
(b)(1)(iii) of this section, the Administrator will provide an 
opportunity for submission of objections to the identification of CSAPR 
NOX Annual units in such notice.

    (B) The Administrator will adjust the identification of CSAPR 
NOX Annual units in each notice of data availability required 
in paragraph (b)(1)(iii) of this section to the extent necessary to 
ensure that it is in accordance with paragraph (b)(1)(iii) of this 
section and will calculate the CSAPR NOX Annual allowance 
allocation to each CSAPR NOX Annual unit in accordance with 
Sec. 97.412(a)(9), (10), and (12) and Sec. Sec. 97.406(b)(2) and 
97.430 through 97.435. By February 15 immediately after the promulgation 
of each notice of data availability required in paragraph (b)(1)(iii) of 
this section, the Administrator will promulgate a notice of data 
availability of any adjustments of the identification of CSAPR 
NOX Annual units that the Administrator determines to be 
necessary, the reasons for accepting or rejecting any objections 
submitted in accordance with paragraph (b)(1)(iv)(A) of this section, 
and the results of such calculations.
    (v) To the extent any CSAPR NOX Annual allowances are 
added to the new unit set-aside after promulgation of each notice of 
data availability required in paragraph (b)(1)(iv) of this section for a 
control period before 2021, or in paragraph (b)(1)(ii) of this section 
for a control period in 2021 or thereafter, the Administrator will 
promulgate additional notices of data availability, as deemed 
appropriate, of the allocation of such CSAPR NOX Annual 
allowances in accordance with Sec. 97.412(a)(10).
    (2) Indian country new unit set-asides. (i)(A) By June 1 of each 
year from 2015 through 2020, the Administrator will calculate the CSAPR

[[Page 216]]

provide an opportunity for submission of objections to the calculations 
referenced in such notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(2)(i) of this 
section and shall be limited to addressing whether the calculations 
(including the identification of the CSAPR NOX Annual units) 
are in accordance with the provisions referenced in paragraph 
(b)(2)(i)(A) or (B) of this section, as applicable.
    (B) The Administrator will adjust the calculations to the extent

    (c) Units incorrectly allocated CSAPR NOX Annual 
allowances. (1) For each control period in 2015 and thereafter, if the 
Administrator determines that CSAPR NOX Annual allowances 
were allocated under paragraph (a) of this section, or under a provision 
of a SIP revision approved under Sec. 52.38(a)(3), (4), or (5) of this 
chapter, where such control period and the recipient are covered by the 
provisions of paragraph (c)(1)(i) of this section or were allocated 
under Sec. 97.412(a)(2) through (7), (9), and (12) and (b)(2) through 
(7), (9),

[[Page 217]]

and (12), or under a provision of a SIP revision approved under Sec. 
52.38(a)(4) or (5) of this chapter, where such control period and the 
recipient are covered by the provisions of paragraph (c)(1)(ii) of this 
section, then the Administrator will notify the designated 
representative of the recipient and will act in accordance with the 
procedures set forth in paragraphs (c)(2) through (5) of this section:
    (i)(A) The recipient is not actually a CSAPR NOX Annual 
unit under Sec. 97.404 as of January 1, 2015 and is allocated CSAPR 
NOX Annual allowances for such control period or, in the case 
of an allocation under a provision of a SIP revision approved under 
Sec. 52.38(a)(3), (4), or (5) of this chapter, the recipient is not 
actually a CSAPR NOX Annual unit as of January 1, 2015 and is 
allocated CSAPR NOX Annual allowances for such control period 
that the SIP revision provides should be allocated only to recipients 
that are CSAPR NOX Annual units as of January 1, 2015; or
    (B) The recipient is not located as of January 1 of the control 
period in the State from whose NOX Annual trading budget the 
CSAPR NOX Annual allowances allocated under paragraph (a) of 
this section, or under a provision of a SIP revision approved under 
Sec. 52.38(a)(3), (4), or (5) of this chapter, were allocated for such 
control period.
    (ii) The recipient is not actually a CSAPR NOX Annual 
unit under Sec. 97.404 as of January 1 of such control period and is 
allocated CSAPR NOX Annual allowances for such control period 
or, in the case of an allocation under a provision of a SIP revision 
approved under Sec. 52.38(a)(4) or (5) of this chapter, the recipient 
is not actually a CSAPR NOX Annual unit as of January 1 of 
such control period and is allocated CSAPR NOX Annual 
allowances for such control period that the SIP revision provides should 
be allocated only to recipients that are CSAPR NOX Annual 
units as of January 1 of such control period.
    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such CSAPR NOX Annual 
allowances under Sec. 97.421.
    (3) If the Administrator already recorded such CSAPR NOX 
Annual allowances under Sec. 97.421 and if the Administrator makes the 
determination under paragraph (c)(1) of this section before making 
deductions for the source that includes such recipient under Sec. 
97.424(b) for such control period, then the Administrator will deduct 
from the account in which such CSAPR NOX Annual allowances 
were recorded an amount of CSAPR NOX Annual allowances 
allocated for the same or a prior control period equal to the amount of 
such already recorded CSAPR NOX Annual allowances. The 
authorized account representative shall ensure that there are sufficient 
CSAPR NOX Annual allowances in such account for completion of 
the deduction.
    (4) If the Administrator already recorded such CSAPR NOX 
Annual allowances under Sec. 97.421 and if the Administrator makes the 
determination under paragraph (c)(1) of this section after making 
deductions for the source that includes such recipient under Sec. 
97.424(b) for such control period, then the Administrator will not make 
any deduction to take account of such already recorded CSAPR 
NOX Annual allowances.
    (5)(i) With regard to the CSAPR NOX Annual allowances 
that are not recorded, or that are deducted as an incorrect allocation, 
in accordance with paragraphs (c)(2) and (3) of this section for a 
recipient under paragraph (c)(1)(i) of this section, the Administrator 
will:
    (A) Transfer such CSAPR NOX Annual allowances to the new 
unit set-aside for such control period (or a subsequent control period) 
for the State from whose NOX Annual trading budget the CSAPR 
NOX Annual allowances were allocated; or
    (B) If the State has a SIP revision approved under Sec. 52.38(a)(4) 
or (5) of this chapter covering such control period, include such CSAPR 
NOX Annual allowances in the portion of the State 
NOX Annual trading budget that may be allocated for such 
control period (or a subsequent control period) in accordance with such 
SIP revision.
    (ii) With regard to the CSAPR NOX Annual allowances that 
were not allocated from the Indian country new unit set-aside for such 
control period and that are not recorded, or that are deducted as an 
incorrect allocation, in accordance with paragraphs (c)(2) and

[[Page 218]]

(3) of this section for a recipient under paragraph (c)(1)(ii) of this 
section, the Administrator will:
    (A) Transfer such CSAPR NOX Annual allowances to the new

    (iii) CSAPR NOX Annual units that are allocated an amount 
of CSAPR NOX Annual allowances for such control period in the 
notice of data availability issued under Sec. 97.411(a)(1), which 
allocation is terminated for such control period pursuant to Sec. 
97.411(a)(2), and that operate during the control period immediately 
preceding such control period, for allocations for a control period 
before 2021, or that operate during such control period, for allocations 
for a control period in 2021 or thereafter; or
    (iv) For purposes of paragraph (a)(9) of this section, CSAPR 
NOX Annual units under Sec. 97.411(c)(1)(ii) whose 
allocation of an amount of CSAPR NOX Annual allowances for 
such control period in the notice of data availability issued under 
Sec. 97.411(b)(1)(ii)(B) is covered by Sec. 97.411(c)(2) or (3).
    (2) The Administrator will establish a separate new unit set-aside 
for the State for each such control period. Each such new unit set-aside 
will be allocated CSAPR NOX Annual allowances in an amount 
equal to the applicable amount of tons of NOX emissions as 
set forth in Sec. 97.410(a) and will be allocated additional CSAPR 
NOX Annual allowances (if any) in accordance with Sec. 
97.411(a)(2) and (c)(5) and paragraph (b)(10) of this section.
    (3) The Administrator will determine, for each CSAPR NOX

97.430(b), for allocations for a control period in 2021 or thereafter;
    (iii) For a unit described in paragraph (a)(1)(ii) of this section, 
the first control period in which the CSAPR NOX Annual unit 
operates in the State after operating in another jurisdiction and for 
which the unit is not already allocated one or more CSAPR NOX 
Annual allowances; and
    (iv) For a unit described in paragraph (a)(1)(iii) of this section, 
the first control period after the control period in which the unit 
resumes operation, for allocations for a control period before 2021, or 
the control period in which the unit resumes operation, for allocations 
for a control period in 2021 or thereafter.
    (4)(i) The allocation to each CSAPR NOX Annual unit 
described in paragraphs (a)(1)(i) through (iii) of this section and for 
each control period described in paragraph (a)(3) of this section will 
be an amount equal to the unit's total tons of NOX emissions 
during the immediately preceding control period, for allocations for a 
control period before 2021, or the unit's total tons of NOX 
emissions during the control period, for allocations for a control 
period in 2021 or thereafter.
    (ii) The Administrator will adjust the allocation amount in 
paragraph (a)(4)(i) of this section in accordance with paragraphs (a)(5) 
through (7) and (12) of this section.
    (5) The Administrator will calculate the sum of the allocation 
amounts of CSAPR NOX Annual allowances determined for all 
such CSAPR NOX Annual units under paragraph (a)(4)(i) of this 
section in the State for such control period.
    (6) If the amount of CSAPR NOX Annual allowances in the 
new unit set-aside for the State for such control period is greater than 
or equal to the sum under paragraph (a)(5) of this section, then the 
Administrator will allocate the amount of CSAPR NOX Annual 
allowances determined for each such CSAPR NOX Annual unit 
under paragraph (a)(4)(i) of this section.
    (7) If the amount of CSAPR NOX Annual allowances in the 
new unit set-aside for the State for such control period is less than 
the sum under paragraph (a)(5) of this section, then the Administrator 
will allocate to each such CSAPR NOX Annual unit the amount 
of the CSAPR NOX Annual allowances determined under paragraph 
(a)(4)(i) of this section for the unit, multiplied by the amount of 
CSAPR NOX Annual allowances in the new unit set-aside for 
such control period, divided by the sum under paragraph (a)(5) of this 
section, and rounded to the nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.411(b)(1)(i) and (ii), of the amount of CSAPR 
NOX Annual allowances allocated under paragraphs (a)(2) 
through (7) and (12) of this section for such control period to each 
CSAPR NOX Annual unit eligible for such allocation.
    (9) For a control period before 2021, if, after completion of the 
procedures under paragraphs (a)(5) through (8) of this section for such 
control period, any unallocated CSAPR NOX Annual allowances 
remain in the new unit set-aside for the State for such control period, 
the Administrator will allocate such CSAPR NOX Annual 
allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (a)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such 
control period and ending November 30 of the year of such control 
period, the positive difference (if any) between the unit's emissions 
during such control period and the amount of CSAPR NOX Annual 
allowances referenced in the notice of data availability required under 
Sec. 97.411(b)(1)(ii) for the unit for such control period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (a)(9)(i) of this section;

[[Page 220]]

    (iii) If the amount of unallocated CSAPR NOX Annual 
allowances remaining in the new unit set-aside for the State for such 
control period is greater than or equal to the sum determined under 
paragraph (a)(9)(ii) of this section, then the Administrator will 
allocate the amount of CSAPR NOX Annual allowances determined 
for each such CSAPR NOX Annual unit under paragraph (a)(9)(i) 
of this section; and
    (iv) If the amount of unallocated CSAPR NOX Annual 
allowances remaining in the new unit set-aside for the State for such 
control period is less than the sum under paragraph (a)(9)(ii) of this 
section, then the Administrator will allocate to each such CSAPR 
NOX Annual unit the amount of the CSAPR NOX Annual 
allowances determined under paragraph (a)(9)(i) of this section for the 
unit, multiplied by the amount of unallocated CSAPR NOX 
Annual allowances remaining in the new unit set-aside for such control 
period, divided by the sum under paragraph (a)(9)(ii) of this section, 
and rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (a)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (a)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR NOX 
Annual allowances remain in the new unit set-aside for the State for 
such control period, the Administrator will allocate to each CSAPR 
NOX Annual unit that is in the State, is allocated an amount 
of CSAPR NOX Annual allowances in the notice of data 
availability issued under Sec. 97.411(a)(1), and continues to be 
allocated CSAPR NOX Annual allowances for such control period 
in accordance with Sec. 97.411(a)(2), an amount of CSAPR NOX 
Annual allowances equal to the following: The total amount of such 
remaining unallocated CSAPR NOX Annual allowances in such new 
unit set-aside, multiplied by the unit's allocation under Sec. 
97.411(a) for such control period, divided by the remainder of the 
amount of tons in the applicable State NOX Annual trading 
budget minus the sum of the amounts of tons in such new unit set-aside 
and the Indian country new unit set-aside for the State for such control 
period, and rounded to the nearest allowance.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.411(b)(1)(iii), (iv), and (v), of the 
amount of CSAPR NOX Annual allowances allocated under 
paragraphs (a)(9), (10), and (12) of this section for such control 
period to each CSAPR NOX Annual unit eligible for such 
allocation.
    (ii) For a control period in 2021 or thereafter, the Administrator 
will notify the public, through the promulgation of the notices of data

amount of CSAPR NOX Annual allowances allocated under 
paragraphs (a)(2) through (7), (10), and (12) of this section for such 
control period to each CSAPR NOX Annual unit eligible for 
such allocation.
    (12) Notwithstanding the requirements of paragraphs (a)(2) through 
(11) of this section, if the calculations of allocations from a new unit 
set-aside for a control period before 2021 under paragraph (a)(7) of 
this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or 
paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a 
control period in 2021 or thereafter under paragraph (a)(7) of this 
section or paragraphs (a)(6) and (10) of this section, would otherwise 
result in total allocations from such new unit set-aside unequal to the 
total amount of such new unit set-aside, then the Administrator will 
adjust the results of such calculations as follows. The Administrator 
will list the CSAPR NOX Annual units in descending order 
based on such units' allocation amounts under paragraph (a)(7), 
(a)(9)(iv), or (a)(10) of this section, as applicable, and, in cases of 
equal allocation amounts, in alphabetical order of the relevant sources' 
names and numerical order of the relevant units' identification numbers, 
and will adjust each unit's allocation amount under such paragraph 
upward or downward by one CSAPR NOX Annual allowance (but not 
below zero) in the order in which the units are listed, and will repeat 
this adjustment process as necessary, until the total allocations from

Sec. 97.424  Compliance with CSAPR NOX Annual emissions limitation.

    (a) Availability for deduction for compliance. CSAPR NOX 
Annual allowances are available to be deducted for compliance with a 
source's CSAPR NOX Annual emissions limitation for a control 
period in a given year only if the CSAPR NOX Annual 
allowances:
    (1) Were allocated or auctioned for such control period or a control 
period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance 
transfer deadline for such control period.
    (b) Deductions for compliance. After the recordation, in accordance 
with Sec. 97.423, of CSAPR NOX Annual allowance transfers 
submitted by the allowance transfer deadline for a control period in a 
given year, the Administrator will deduct from each source's compliance 
account CSAPR NOX Annual allowances available under paragraph 
(a) of this section in order to determine whether the source meets the 
CSAPR NOX Annual emissions limitation for such control 
period, as follows:
    (1) Until the amount of CSAPR NOX Annual allowances 
deducted equals the number of tons of total NOX emissions 
from all CSAPR NOX Annual units at the source for such 
control period; or
    (2) If there are insufficient CSAPR NOX Annual allowances 
to complete the deductions in paragraph (b)(1) of this section, until no 
more CSAPR NOX Annual allowances available under paragraph 
(a) of this section remain in the compliance account.
    (c) Selection of CSAPR NOX Annual allowances for deduction--(1) 
Identification by serial number. The designated representative for a 
source may request that specific CSAPR NOX Annual allowances, 
identified by serial number, in the source's compliance account be 
deducted for emissions or excess emissions for a control period in a 
given year in accordance with paragraph (b) or (d) of this section. In 
order to be complete, such request shall be submitted to the 
Administrator by the allowance transfer deadline for such control period 
and include, in a format prescribed by the Administrator, the 
identification of the CSAPR NOX Annual source and the 
appropriate serial numbers.

[[Page 235]]

    (2) First-in, first-out. The Administrator will deduct CSAPR 
NOX Annual allowances under paragraph (b) or (d) of this 
section from the source's compliance account in accordance with a 
complete request under paragraph (c)(1) of this section or, in the 
absence of such request or in the case of identification of an 
insufficient amount of CSAPR NOX Annual allowances in such 
request, on a first-in, first-out accounting basis in the following 
order:
    (i) Any CSAPR NOX Annual allowances that were recorded in 
the compliance account pursuant to Sec. 97.421 and not transferred out 
of the compliance account, in the order of recordation; and then
    (ii) Any other CSAPR NOX Annual allowances that were 
transferred to and recorded in the compliance account pursuant to this 
subpart, in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the CSAPR NOX Annual source has excess 
emissions, the Administrator will deduct from the source's compliance 
account an amount of CSAPR NOX Annual allowances, allocated 
or auctioned for a control period in a prior year or the control period 
in the year of the excess emissions or in the immediately following 
year, equal to two times the number of tons of the source's excess 
emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

Sec. 97.425  Compliance with CSAPR NOX Annual assurance provisions.

    (a) Availability for deduction. CSAPR NOX Annual 
allowances are available to be deducted for compliance with the CSAPR 
NOX Annual assurance provisions for a control period in a 
given year by the owners and operators of a group of one or more CSAPR 
NOX Annual sources and units in a State (and Indian country 
within the borders of such State) only if the CSAPR NOX 
Annual allowances:
    (1) Were allocated or auctioned for a control period in a prior year 
or the control period in the given year or in the immediately following 
year; and
    (2) Are held in the assurance account, established by the 
Administrator for such owners and operators of such group of CSAPR 
NOX Annual sources and units in such State (and Indian 
country within the borders of such State) under paragraph (b)(3) of this 
section, as of the deadline established in paragraph (b)(4) of this 
section.
    (b) Deductions for compliance. The Administrator will deduct CSAPR 
NOX Annual allowances available under paragraph (a) of this 
section for compliance with the CSAPR NOX Annual assurance 
provisions for a State for a control period in a given year in 
accordance with the following procedures:
    (1) By June 1 of each year from 2018 through 2021 and August 1 of 
each year thereafter, the Administrator will:
    (i) Calculate, for each State (and Indian country within the borders 
of such State), the total NOX emissions from all CSAPR 
NOX Annual units at CSAPR NOX Annual sources in 
the State (and Indian country within the borders of such State) during 
the control period in the year before the year of this calculation 
deadline and the amount, if any, by which such total NOX 
emissions exceed the State assurance level as described in Sec. 
97.406(c)(2)(iii); and
    (ii) For the set of any States (and Indian country within the 
borders of such States) for which the results of the calculations 
required in paragraph (b)(1)(i) of this section indicate that total 
NOX emissions exceed the respective State assurance levels 
for such control period--
    (A) Calculate, for each such State (and Indian country within the 
borders of such State) and such control period and each common 
designated representative for such control period for a group of one or 
more CSAPR NOX Annual sources and units in such State (and 
such Indian country), the common designated representative's share of 
the total NOX emissions from all CSAPR NOX Annual 
units at CSAPR

[[Page 236]]

NOX Annual sources in such State (and such Indian country), 
the common designated representative's assurance level, and the amount 
(if any) of CSAPR NOX Annual allowances that the owners and 
operators of such group of sources and units must hold in accordance 
with the calculation formula in Sec. 97.406(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the NOX emissions 
from each CSAPR NOX Annual source in each such State (and 
Indian country within the borders of such State).
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.406(c)(2)(iii), Sec. Sec. 97.406(b) and 97.430 through 97.435, the 
definitions of ``common designated representative'', ``common designated 
representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.402, and the calculation formula in 
Sec. 97.406(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1 
immediately after the promulgation of such notice, the Administrator 
will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) For any State (and Indian country within the borders of such 
State) referenced in each notice of data availability required in 
paragraph (b)(2)(ii) of this section as having CSAPR NOX 
Annual units with total NOX emissions exceeding the State 
assurance level for a control period in a given year, the Administrator 
will establish one assurance account for each set of owners and 
operators referenced, in the notice of data availability required under 
paragraph (b)(2)(ii) of this section, as all of the owners and operators 
of a group of CSAPR NOX Annual sources and units in the State 
(and Indian country within the borders of such State) having a common 
designated representative for such control period and as being required 
to hold CSAPR NOX Annual allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate CSAPR NOX Annual 
sources, CSAPR NOX Annual units, and State (and Indian 
country within the borders of such State) under paragraph (b)(3) of this 
section a total amount of CSAPR NOX Annual allowances, 
available for deduction under paragraph (a) of this section, equal to 
the amount such owners and operators are required to hold with regard to 
such sources, units and State (and Indian country within the borders of 
such State) as calculated by the Administrator and referenced in such 
notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.423, of CSAPR 
NOX Annual allowance transfers submitted by midnight of such 
date, the Administrator will determine whether the owners and operators 
described in paragraph (b)(3) of this section hold, in the assurance 
account for the appropriate CSAPR NOX Annual sources, CSAPR 
NOX Annual units, and State (and Indian country within the

[[Page 237]]

borders of such State) established under paragraph (b)(3) of this 
section, the amount of CSAPR NOX Annual allowances available 
under paragraph (a) of this section that the owners and operators are 
required to hold with regard to such sources, units, and State (and 
Indian country within the borders of such State) as calculated by the 
Administrator and referenced in the notice required in paragraph 
(b)(2)(ii) of this section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR NOX Annual allowances that the owners and 
operators are required to hold in accordance with Sec. 97.406(c)(2)(i) 
for such control period shall continue to be such amounts as calculated 
by the Administrator and referenced in such notice required in paragraph 
(b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator will use the 
data as so revised to recalculate the amounts of CSAPR NOX 
Annual allowances that owners and operators are required to hold in 
accordance with the calculation formula in Sec. 97.406(c)(2)(i) for 
such control period with regard to the CSAPR NOX Annual 
sources, CSAPR NOX Annual units, and State (and Indian 
country within the borders of such State) involved, provided that such 
litigation under part 78 of this chapter, or the proceeding under part 
78 of this chapter that resulted in the decision appealed in such 
litigation under section 307 of the Clean Air Act, was initiated no 
later than 30 days after promulgation of such notice required in 
paragraph (b)(2)(ii) of this section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of CSAPR 
NOX Annual allowances that the owners and operators are 
required to hold for such control period with regard to the CSAPR 
NOX Annual sources, CSAPR NOX Annual units, and 
State (and Indian country within the borders of such State) involved--
    (A) Where the amount of CSAPR NOX Annual allowances that 
the owners and operators are required to hold increases as a result of 
the use of all such revised data, the Administrator will establish a 
new, reasonable deadline on which the owners and operators shall hold 
the additional amount of CSAPR NOX Annual allowances in the 
assurance account established by the Administrator for the appropriate 
CSAPR NOX Annual sources, CSAPR NOX Annual units, 
and State (and Indian country within the borders of such State) under 
paragraph (b)(3) of this section. The owners' and operators' failure to 
hold such additional amount, as required, before the new deadline shall 
not be a violation of the Clean Air Act. The owners' and operators' 
failure to hold such additional amount, as required, as of the new 
deadline shall be a violation of the Clean Air Act. Each CSAPR 
NOX Annual allowance that the owners and operators fail to 
hold as required as of the new deadline, and each day in such control 
period, shall be a separate violation of the Clean Air Act.
    (B) For the owners and operators for which the amount of CSAPR 
NOX Annual allowances required to be held decreases as a 
result of the use of all such revised data, the Administrator will 
record, in all accounts from which CSAPR NOX Annual 
allowances were transferred by such owners and operators for such 
control period to the assurance account established by the Administrator 
for the appropriate CSAPR NOX Annual sources, CSAPR 
NOX Annual units, and State (and Indian country within the 
borders of such State) under paragraph (b)(3) of this section, a total 
amount of the CSAPR NOX Annual allowances held in such 
assurance

[[Page 238]]

account equal to the amount of the decrease. If CSAPR NOX 
Annual allowances were transferred to such assurance account from more 
than one account, the amount of CSAPR NOX Annual allowances 
recorded in each such transferor account will be in proportion to the 
percentage of the total amount of CSAPR NOX Annual allowances 
transferred to such assurance account for such control period from such 
transferor account.
    (C) Each CSAPR NOX Annual allowance held under paragraph 
(b)(6)(iii)(A) of this section as a result of recalculation of 
requirements under the CSAPR NOX Annual assurance provisions 
for such control period must be a CSAPR NOX Annual allowance 
allocated for a control period in a year before or the year immediately 
following, or in the same year as, the year of such control period.

date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CSAPR NOX Annual Trading Program 
for a period not to exceed 120 days after receipt by the Administrator 
of the complete certification application for the monitoring system 
under paragraph (d)(3)(ii) of this section. Data measured and recorded 
by the provisionally certified monitoring system, in accordance with the 
requirements of part 75 of this chapter, will be considered valid 
quality-assured data (retroactive to the date and time of provisional 
certification), provided that the Administrator does not invalidate the 
provisional certification by issuing a notice of disapproval within 120 
days of the date of receipt of the complete certification application by 
the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph

    (a) General provisions. Whenever any monitoring system fails to meet 
the quality-assurance and quality-control requirements or data 
validation requirements of part 75 of this chapter, data shall be 
substituted using the applicable missing data procedures in subpart D or 
subpart H of, or appendix D or appendix E to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.431 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.431 for 
each disapproved monitoring system.

    (4) The Administrator may review and conduct independent audits of 
any quarterly report in order to determine whether the quarterly report 
meets the requirements of this subpart and part 75 of this chapter, 
including the requirement to use substitute data.
    (i) The Administrator will notify the designated representative of 
any determination that the quarterly report fails to meet any such 
requirements and specify in such notification any corrections that the 
Administrator believes are necessary to make through resubmission of the 
quarterly report and a reasonable time period within which the 
designated representative must respond. Upon request by the designated 
representative, the Administrator may specify reasonable extensions of 
such time period. Within the time period (including any such extensions) 
specified by the Administrator, the designated representative shall 
resubmit the quarterly report with the corrections specified by the 
Administrator, except to the extent the designated representative 
provides information demonstrating that a specified correction is not 
necessary because the quarterly report already meets the requirements of 
this subpart and part 75 of this chapter that are relevant to the 
specified correction.
    (ii) Any resubmission of a quarterly report shall meet the 
requirements applicable to the submission of a quarterly report under 
this subpart and part 75 of this chapter, except for the deadline set 
forth in paragraph (d)(2) of this section.
    (e) Compliance certification. The designated representative shall 
submit to the Administrator a compliance certification (in a format 
prescribed by the Administrator) in support of each quarterly report 
based on reasonable inquiry of those persons with primary responsibility

Sec. 97.511  Timing requirements for CSAPR NOX Ozone Season Group 1 allowance allocations.

    (a) Existing units. (1) CSAPR NOX Ozone Season Group 1 
allowances are allocated, for the control periods in 2015 and each year 
thereafter, as provided in a notice of data availability issued by the 
Administrator. Providing an allocation to a unit in such notice does not 
constitute a determination that the unit is a CSAPR NOX Ozone 
Season Group 1 unit, and not providing an allocation to a unit in such 
notice does not constitute a determination that the unit is not a CSAPR 
NOX Ozone Season Group 1 unit.
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting after 2014, 
during the control period in two consecutive years, such unit will not 
be allocated the CSAPR NOX Ozone Season Group 1 allowances 
provided in such notice for the unit for the control periods in the 
fifth year after the first such year and in each year after that fifth 
year. All CSAPR NOX Ozone Season Group 1 allowances that 
would otherwise have been allocated to such unit will be allocated to 
the new unit set-aside for the State where such unit is located and for 
the respective years involved. If such unit resumes operation, the 
Administrator will allocate CSAPR NOX Ozone Season Group 1 
allowances to the unit in accordance with paragraph (b) of this section.

(10), and (12) and Sec. Sec. 97.506(b)(2) and 97.530 through 97.535, 
for the control period in the year before the year of the applicable 
calculation deadline under this paragraph and will promulgate a notice 
of data availability of the results of the calculations.

amounts of CSAPR NOX Ozone Season Group 1 allowances 
determined for all such CSAPR NOX Ozone Season Group 1 units 
under paragraph (a)(4)(i) of this section in the State for such control 
period.
    (6) If the amount of CSAPR NOX Ozone Season Group 1 
allowances in the new unit set-aside for the State for such control 
period is greater than or equal to the sum under paragraph (a)(5) of 
this section, then the Administrator will allocate the amount of CSAPR 
NOX Ozone Season Group 1 allowances determined for each such 
CSAPR NOX Ozone Season Group 1 unit under paragraph (a)(4)(i) 
of this section.
    (7) If the amount of CSAPR NOX Ozone Season Group 1 
allowances in the new unit set-aside for the State for such control 
period is less than the sum under paragraph (a)(5) of this section, then 
the Administrator will allocate to each such CSAPR NOX Ozone 
Season Group 1 unit the amount of the CSAPR NOX Ozone Season 
Group 1 allowances determined under paragraph (a)(4)(i) of this section 
for the unit, multiplied by the amount of CSAPR NOX Ozone 
Season Group 1 allowances in the new unit set-aside for such control 
period, divided by the sum under paragraph (a)(5) of this section, and 
rounded to the nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.511(b)(1)(i) and (ii), of the amount of CSAPR

allocate the amount of CSAPR NOX Ozone Season Group 1 
allowances determined for each such CSAPR NOX Ozone Season 
Group 1 unit under paragraph (a)(9)(i) of this section; and
    (iv) If the amount of unallocated CSAPR NOX Ozone Season 
Group 1 allowances remaining in the new unit set-aside for the State for 
such control period is less than the sum under paragraph (a)(9)(ii) of 
this section, then the Administrator will allocate to each such CSAPR 
NOX Ozone Season Group 1 unit the amount of the CSAPR 
NOX Ozone Season Group 1 allowances determined under 
paragraph (a)(9)(i) of this section for the unit, multiplied by

[[Page 269]]

the amount of unallocated CSAPR NOX Ozone Season Group 1 
allowances remaining in the new unit set-aside for such control period, 
divided by the sum under paragraph (a)(9)(ii) of this section, and 
rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (a)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (a)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR NOX Ozone 
Season Group 1 allowances remain in the new unit set-aside for the State 
for such control period, the Administrator will allocate to each CSAPR 
NOX Ozone Season Group 1 unit that is in the State, is 
allocated an amount of CSAPR NOX Ozone Season Group 1 
allowances in the notice of data availability issued under Sec. 
97.511(a)(1), and continues to be allocated CSAPR NOX Ozone 
Season Group 1 allowances for such control period in accordance with 
Sec. 97.511(a)(2), an amount of CSAPR NOX Ozone Season Group 
1 allowances equal to the following: The total amount of such remaining 
unallocated CSAPR NOX Ozone Season Group 1 allowances in such 
new unit set-aside, multiplied by the unit's allocation under Sec. 
97.511(a) for such control period, divided by the remainder of the 
amount of tons in the applicable State NOX Ozone Season Group 
1 trading budget minus the sum of the amounts of tons in such new unit 
set-aside and the Indian country new unit set-aside for the State for 
such control period, and rounded to the nearest allowance.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.511(b)(1)(iii), (iv), and (v), of the 
amount of CSAPR NOX Ozone Season Group 1 allowances allocated 
under paragraphs (a)(9), (10), and (12) of this section for such control 
period to each CSAPR NOX Ozone Season Group 1 unit eligible 
for such allocation.
    (ii) For a control period in 2021 or thereafter, the Administrator 
will notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.511(b)(1)(i), (ii), and (v), of the 
amount of CSAPR NOX Ozone Season Group 1 allowances allocated

such control period to each CSAPR NOX Ozone Season Group 1 
unit eligible for such allocation.
    (12) Notwithstanding the requirements of paragraphs (a)(2) through 
(11) of this section, if the calculations of allocations from a new unit 
set-aside for a control period before 2021 under paragraph (a)(7) of 
this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or 
paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a 
control period in 2021 or thereafter under paragraph (a)(7) of this 
section or paragraphs (a)(6) and (10) of this section, would otherwise 
result in total allocations from such new unit set-aside unequal to the 
total amount of such new unit set-aside, then the Administrator will 
adjust the results of such calculations as follows. The Administrator 
will list the CSAPR NOX Ozone Season Group 1 units in 
descending order based on such units' allocation amounts under paragraph 
(a)(7), (a)(9)(iv), or (a)(10) of this section, as applicable, and, in 
cases of equal allocation amounts, in alphabetical order of the relevant 
sources' names and numerical order of the relevant units' identification 
numbers, and will adjust each unit's allocation amount under such 
paragraph upward or downward by one CSAPR NOX Ozone Season 
Group 1 allowance (but not below zero) in the order in which the units 
are listed, and will repeat this adjustment process as necessary, until 
the total allocations from such new unit set-aside equal the total 
amount of such new unit set-aside.
    (b) Allocations from Indian country new unit set-asides. For each 
control period in 2015 and thereafter and for the CSAPR NOX 
Ozone Season Group 1 units in Indian country within the borders of each

control period and the amount of CSAPR NOX Ozone Season Group 
1 allowances referenced in the notice of data availability required 
under Sec. 97.511(b)(2)(ii) for the unit for such control period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (b)(9)(i) of this section;
    (iii) If the amount of unallocated CSAPR NOX Ozone Season 
Group 1 allowances remaining in the Indian country new unit set-aside 
for the State for such control period is greater than or equal to the 
sum determined under paragraph (b)(9)(ii) of this section, then the 
Administrator will allocate the amount of CSAPR NOX Ozone 
Season Group 1 allowances determined for each such CSAPR NOX 
Ozone Season Group 1 unit under paragraph (b)(9)(i) of this section; and
    (iv) If the amount of unallocated CSAPR NOX Ozone Season 
Group 1 allowances remaining in the Indian country new unit set-aside 
for the State for such control period is less than the sum under 
paragraph (b)(9)(ii) of this section, then the Administrator will 
allocate to each such CSAPR NOX Ozone Season Group 1 unit the 
amount of the CSAPR NOX Ozone Season Group 1 allowances 
determined under paragraph (b)(9)(i) of this section for the unit, 
multiplied by the amount of unallocated CSAPR NOX Ozone 
Season Group 1 allowances remaining in the Indian country new unit set-
aside for such control period, divided by the sum under paragraph 
(b)(9)(ii) of this section, and rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (b)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (b)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR NOX Ozone 
Season Group 1 allowances remain in the Indian country new unit set-
aside for the State for such control period, the Administrator will:
    (i) Transfer such unallocated CSAPR NOX Ozone Season 
Group 1 allowances to the new unit set-aside for the State for such 
control period; or
    (ii) If the State has a SIP revision approved under Sec. 
52.38(b)(4) or (5) of this chapter covering such control period, include 
such unallocated CSAPR NOX Ozone Season Group 1 allowances in 
the portion of the State NOX Ozone Season Group 1 trading 
budget that may be allocated for such control period in accordance with 
such SIP revision.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.511(b)(2)(iii), (iv), and (v), of the 
amount of CSAPR NOX Ozone Season Group 1 allowances allocated 
under paragraphs (b)(9), (10), and (12) of this section for such control 
period to each CSAPR NOX Ozone Season Group 1 unit eligible 
for such allocation.

[[Page 272]]

    (ii) For a control period in 2021 or thereafter, the Administrator 
will notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.511(b)(2)(i), (ii), and (v), of the 
amount of CSAPR NOX Ozone Season Group 1 allowances allocated 
under paragraphs (b)(2) through (7), (10), and (12) of this section for 
such control period to each CSAPR NOX Ozone Season Group 1 
unit eligible for such allocation.
    (12) Notwithstanding the requirements of paragraphs (b)(2) through 
(11) of this section, if the calculations of allocations from an Indian 
country new unit set-aside for a control period before 2021 under 
paragraph (b)(7) of this section or paragraphs (b)(6) and (b)(9)(iv) of 
this section, or for a control period in 2021 or thereafter under 
paragraph (b)(7) of this section, would otherwise result in total 
allocations from such Indian country new unit set-aside unequal to the 
total amount of such Indian country new unit set-aside, then the 
Administrator will adjust the results of such calculations as follows. 
The Administrator will list the CSAPR NOX Ozone Season Group 
1 units in descending order based on such units' allocation amounts 
under paragraph (b)(7) or (b)(9)(iv) of this section, as applicable, 
and, in cases of equal allocation amounts, in alphabetical order of the 
relevant sources' names and numerical order of the relevant units' 
identification numbers, and will adjust each unit's allocation amount 
under such paragraph upward or downward by one CSAPR NOX 
Ozone Season Group 1 allowance (but not below zero) in the order in 
which the units are listed, and will repeat this adjustment process as 
necessary, until the total allocations from such Indian country new unit 
set-aside equal the total amount of such Indian country new unit set-
aside.

    (a) Availability for deduction for compliance. CSAPR NOX 
Ozone Season Group 1 allowances are available to be deducted for 
compliance with a source's CSAPR NOX Ozone Season Group 1 
emissions limitation for a control period in a given year only if the 
CSAPR NOX Ozone Season Group 1 allowances:
    (1) Were allocated or auctioned for such control period or a control 
period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance 
transfer deadline for such control period.

with Sec. 97.523, of CSAPR NOX Ozone Season Group 1 
allowance transfers submitted by the allowance transfer deadline for a 
control period in a given year, the Administrator will deduct from each 
source's compliance account CSAPR NOX Ozone Season Group 1 
allowances available under paragraph (a) of this section in order to 
determine whether the source meets the CSAPR NOX Ozone Season 
Group 1 emissions limitation for such control period, as follows:
    (1) Until the amount of CSAPR NOX Ozone Season Group 1 
allowances deducted equals the number of tons of total NOX 
emissions from all CSAPR NOX Ozone Season Group 1 units at 
the source for such control period; or
    (2) If there are insufficient CSAPR NOX Ozone Season 
Group 1 allowances

[[Page 285]]

to complete the deductions in paragraph (b)(1) of this section, until no 
more CSAPR NOX Ozone Season Group 1 allowances available 
under paragraph (a) of this section remain in the compliance account.
    (c) Selection of CSAPR NOX Ozone Season Group 1 allowances for 
deduction--(1) Identification by serial number. The designated 
representative for a source may request that specific CSAPR 
NOX Ozone Season Group 1 allowances, identified by serial 
number, in the source's compliance account be deducted for emissions or 
excess emissions for a control period in a given year in accordance with 
paragraph (b) or (d) of this section. In order to be complete, such 
request shall be submitted to the Administrator by the allowance 
transfer deadline for such control period and include, in a format 
prescribed by the Administrator, the identification of the CSAPR 
NOX Ozone Season Group 1 source and the appropriate serial 
numbers.
    (2) First-in, first-out. The Administrator will deduct CSAPR 
NOX Ozone Season Group 1 allowances under paragraph (b) or 
(d) of this section from the source's compliance account in accordance 
with a complete request under paragraph (c)(1) of this section or, in 
the absence of such request or in the case of identification of an 
insufficient amount of CSAPR NOX Ozone Season Group 1 
allowances in such request, on a first-in, first-out accounting basis in 
the following order:
    (i) Any CSAPR NOX Ozone Season Group 1 allowances that

year in which the CSAPR NOX Ozone Season Group 1 source has 
excess emissions, the Administrator will deduct from the source's 
compliance account an amount of CSAPR NOX Ozone Season Group 
1 allowances, allocated or auctioned for a control period in a prior 
year or the control period in the year of the excess emissions or in the 
immediately following year, equal to two times the number of tons of the 
source's excess emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

Sec. 97.525  Compliance with CSAPR NOX Ozone Season Group 1 assurance provisions.

    (a) Availability for deduction. CSAPR NOX Ozone Season 
Group 1 allowances are available to be deducted for compliance with the 
CSAPR NOX Ozone Season Group 1 assurance provisions for a 
control period in a given year by the owners and operators of a group of 
one or more CSAPR NOX Ozone Season Group 1 sources and units 
in a State (and Indian country within the borders of such State) only if 
the CSAPR NOX Ozone Season Group 1 allowances:
    (1) Were allocated or auctioned for a control period in a prior year 
or the control period in the given year or in the immediately following 
year; and
    (2) Are held in the assurance account, established by the 
Administrator for such owners and operators of such group of CSAPR 
NOX Ozone Season Group 1 sources and units in such State (and 
Indian country within the borders of such State) under paragraph (b)(3) 
of this section, as of the deadline established in paragraph (b)(4) of 
this section.
    (b) Deductions for compliance. The Administrator will deduct CSAPR 
NOX Ozone Season Group 1 allowances available under paragraph 
(a) of this section for compliance with the CSAPR NOX Ozone 
Season Group 1 assurance provisions for a State for a control period in 
a given year in accordance with the following procedures:
    (1) By June 1 of each year from 2018 through 2021 and August 1 of 
each year thereafter, the Administrator will:
    (i) Calculate, for each State (and Indian country within the borders 
of such

[[Page 286]]

State), the total NOX emissions from all CSAPR NOX 
Ozone Season Group 1 units at CSAPR NOX Ozone Season Group 1 
sources in the State (and Indian country within the borders of such 
State) during the control period in the year before the year of this 
calculation deadline and the amount, if any, by which such total 
NOX emissions exceed the State assurance level as described 
in Sec. 97.506(c)(2)(iii); and
    (ii) For the set of any States (and Indian country within the 
borders of such States) for which the results of the calculations 
required in paragraph (b)(1)(i) of this section indicate that total 
NOX emissions exceed the respective State assurance levels 
for such control period--
    (A) Calculate, for each such State (and Indian country within the 
borders of such State) and such control period and each common 
designated representative for such control period for a group of one or 
more CSAPR NOX Ozone Season Group 1 sources and units in such 
State (and such Indian country), the common designated representative's 
share of the total NOX emissions from all CSAPR 
NOX Ozone Season Group 1 units at CSAPR NOX Ozone 
Season Group 1 sources in such State (and such Indian country), the 
common designated representative's assurance level, and the amount (if 
any) of CSAPR NOX Ozone Season Group 1 allowances that the 
owners and operators of such group of sources and units must hold in 
accordance with the calculation formula in Sec. 97.506(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the NOX emissions 
from each CSAPR NOX Ozone Season Group 1 source in each such 
State (and Indian country within the borders of such State).
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.506(c)(2)(iii), Sec. Sec. 97.506(b) and 97.530 through 97.535, the 
definitions of ``common designated representative'', ``common designated 
representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.502, and the calculation formula in 
Sec. 97.506(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1 
immediately after the promulgation of such notice, the Administrator 
will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) For any State (and Indian country within the borders of such 
State) referenced in each notice of data availability required in 
paragraph (b)(2)(ii) of this section as having CSAPR NOX 
Ozone Season Group 1 units with total NOX emissions exceeding 
the State assurance level for a control period in a given year, the 
Administrator will establish one assurance account for each set of 
owners and operators referenced, in the notice of data availability 
required under paragraph (b)(2)(ii) of this section, as all of the 
owners and operators of a group of CSAPR NOX Ozone Season 
Group 1 sources and units in the State (and Indian country within the 
borders of such State) having a common designated representative for 
such control period and as being required to hold CSAPR NOX 
Ozone Season Group 1 allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate CSAPR NOX Ozone 
Season Group 1 sources, CSAPR NOX Ozone Season Group 1 units, 
and State (and Indian country within the borders of

[[Page 287]]

such State) under paragraph (b)(3) of this section a total amount of 
CSAPR NOX Ozone Season Group 1 allowances, available for 
deduction under paragraph (a) of this section, equal to the amount such 
owners and operators are required to hold with regard to such sources, 
units and State (and Indian country within the borders of such State) as 
calculated by the Administrator and referenced in such notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.523, of CSAPR 
NOX Ozone Season Group 1 allowance transfers submitted by 
midnight of such date, the Administrator will determine whether the 
owners and operators described in paragraph (b)(3) of this section hold, 
in the assurance account for the appropriate CSAPR NOX Ozone 
Season Group 1 sources, CSAPR NOX Ozone Season Group 1 units, 
and State (and Indian country within the borders of such State) 
established under paragraph (b)(3) of this section, the amount of CSAPR 
NOX Ozone Season Group 1 allowances available under paragraph 
(a) of this section that the owners and operators are required to hold 
with regard to such sources, units, and State (and Indian country within 
the borders of such State) as calculated by the Administrator and 
referenced in the notice required in paragraph (b)(2)(ii) of this 
section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR NOX Ozone Season Group 1 allowances that the 
owners and operators are required to hold in accordance with Sec. 
97.506(c)(2)(i) for such control period shall continue to be such 
amounts as calculated by the Administrator and referenced in such notice 
required in paragraph (b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator will use the 
data as so revised to recalculate the amounts of CSAPR NOX 
Ozone Season Group 1 allowances that owners and operators are required 
to hold in accordance with the calculation formula in Sec. 
97.506(c)(2)(i) for such control period with regard to the CSAPR 
NOX Ozone Season Group 1 sources, CSAPR NOX Ozone 
Season Group 1 units, and State (and Indian country within the borders 
of such State) involved, provided that such litigation under part 78 of 
this chapter, or the proceeding under part 78 of this chapter that 
resulted in the decision appealed in such litigation under section 307 
of the Clean Air Act, was initiated no later than 30 days after 
promulgation of such notice required in paragraph (b)(2)(ii) of this 
section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of CSAPR 
NOX Ozone Season Group 1 allowances that the owners and 
operators are required to hold for such control period with regard to 
the CSAPR NOX Ozone Season Group 1 sources, CSAPR 
NOX Ozone Season Group 1 units, and State (and Indian country 
within the borders of such State) involved--
    (A) Where the amount of CSAPR NOX Ozone Season Group 1 
allowances that the owners and operators are required to hold increases 
as a result of the use of all such revised data, the Administrator will 
establish a new, reasonable deadline on which the owners and operators 
shall hold the additional amount of CSAPR NOX Ozone Season 
Group 1 allowances in the assurance account

[[Page 288]]

established by the Administrator for the appropriate CSAPR 
NOX Ozone Season Group 1 sources, CSAPR NOX Ozone 
Season Group 1 units, and State (and Indian country within the borders 
of such State) under paragraph (b)(3) of this section. The owners' and 
operators' failure to hold such additional amount, as required, before 
the new deadline shall not be a violation of the Clean Air Act. The 
owners' and operators' failure to hold such additional amount, as 
required, as of the new deadline shall be a violation of the Clean Air 
Act. Each CSAPR NOX Ozone Season Group 1 allowance that the 
owners and operators fail to hold as required as of the new deadline, 
and each day in such control period, shall be a separate violation of 
the Clean Air Act.
    (B) For the owners and operators for which the amount of CSAPR 
NOX Ozone Season Group 1 allowances required to be held 
decreases as a result of the use of all such revised data, the 
Administrator will record, in all accounts from which CSAPR 
NOX Ozone Season Group 1 allowances were transferred by such 
owners and operators for such control period to the assurance account 
established by the Administrator for the appropriate CSAPR 
NOX Ozone Season Group 1 sources, CSAPR NOX Ozone 
Season Group 1 units, and State (and Indian country within the borders 
of such State) under paragraph (b)(3) of this section, a total amount of 
the CSAPR NOX Ozone Season Group 1 allowances held in such 
assurance account equal to the amount of the decrease. If CSAPR 
NOX Ozone Season Group 1 allowances were transferred to such 
assurance account from more than one account, the amount of CSAPR 
NOX Ozone Season Group 1 allowances recorded in each such 
transferor account will be in proportion to the percentage of the total 
amount of CSAPR NOX Ozone Season Group 1 allowances 
transferred to such assurance account for such control period from such 
transferor account.
    (C) Each CSAPR NOX Ozone Season Group 1 allowance held 
under paragraph (b)(6)(iii)(A) of this section as a result of 
recalculation of requirements under the CSAPR NOX Ozone 
Season Group 1 assurance provisions for such control period must be a 
CSAPR NOX Ozone Season Group 1 allowance allocated for a 
control period in a year before or the year immediately following, or in 
the same year as, the year of such control period.

Sec. 97.526  Banking and conversion.

    (a) A CSAPR NOX Ozone Season Group 1 allowance may be 
banked for future use or transfer in a compliance account or a general 
account in accordance with paragraph (b) of this section.
    (b) Any CSAPR NOX Ozone Season Group 1 allowance that is 
held in a compliance account or a general account will remain in such 
account unless and until the CSAPR NOX Ozone Season Group 1 
allowance is deducted or transferred under Sec. 97.511(c), Sec. 
97.523, Sec. 97.524, Sec. 97.525, Sec. 97.527, or Sec. 97.528 or 
paragraph (c) or (d) of this section.
    (c) At any time after the allowance transfer deadline for the last 
control period for which a State NOX Ozone Season Group 1 
trading budget is set forth in Sec. 97.510(a) for a given State and 
after completion of the procedures under paragraph (d)(1) of this 
section, the Administrator may record a transfer of any CSAPR 
NOX Ozone Season Group 1 allowances held in the compliance 
account for a source in such State (or Indian country within the borders 
of such State) to a general account identified or established by the 
Administrator with the source's designated representative as the 
authorized account representative and with the owners and operators of 
the source (as indicated on the certificate of representation for the 
source) as the persons represented by the authorized account 
representative. The Administrator will notify the designated 
representative not less than 15 days before making such a transfer.
    (d) Notwithstanding any other provision of this subpart, part 52 of 
this chapter, or any SIP revision approved under Sec. 52.38(b)(4) or 
(5) of this chapter:
    (1) As soon as practicable after the completion of deductions under 
Sec. 97.524 for the control period in 2016, but not

[[Page 289]]

later than March 1, 2018, the Administrator will temporarily suspend 
acceptance of CSAPR NOX Ozone Season Group 1 allowance 
transfers submitted under Sec. 97.522 and, before resuming acceptance 
of such transfers, will take the actions in paragraphs (d)(1)(i) through 
(iii) of this section with regard to every general account and every 
compliance account except a compliance account for a CSAPR 
NOX Ozone Season Group 1 source in a State listed in Sec. 
52.38(b)(2)(i) of this chapter (or Indian country within the borders of 
such a State):
    (i) The Administrator will deduct all CSAPR NOX Ozone 
Season Group 1 allowances allocated for the control periods in 2015 and 
2016 from each such account.
    (ii) The Administrator will determine a conversion factor equal to 
the greater of 1.0000 or the quotient, expressed to four decimal places, 
of the sum of all CSAPR NOX Ozone Season Group 1 allowances 
deducted from all such accounts under paragraph (d)(1)(i) of this 
section divided by the product of 1.5 multiplied by the sum of the 
variability limits for the control period in 2017 set forth in Sec. 
97.810(b) for all States except a State listed in Sec. 52.38(b)(2)(i) 
of this chapter.
    (iii) The Administrator will allocate and record in each such 
account an amount of CSAPR NOX Ozone Season Group 2 
allowances for the control period in 2017 computed as the quotient, 
rounded up to the nearest allowance, of the number of CSAPR 
NOX Ozone Season Group 1 allowances deducted from such 
account under paragraph (d)(1)(i) of this section divided by the 
conversion factor determined under paragraph (d)(1)(ii) of this section, 
except as provided in paragraph (d)(1)(iv) of this section.
    (iv) Where, pursuant to paragraph (d)(1)(i) of this section, the 
Administrator deducts CSAPR NOX Ozone Season Group 1 
allowances from the compliance account for a source in a State not 
listed in Sec. 52.38(b)(2)(iii) or (iv) of this chapter (or Indian 
country within the borders of such a State), the Administrator will not 
record CSAPR NOX Ozone Season Group 2 allowances in that 
compliance account but instead will allocate and record the amount of 
CSAPR NOX Ozone Season Group 2 allowances for the control 
period in 2017 computed for such source in accordance with paragraph 
(d)(1)(iii) of this section in a general account identified by the 
designated representative for such source, provided that if the 
designated representative fails to identify such a general account in a 
submission to the Administrator by July 14, 2021, the Administrator may 
record such CSAPR NOX Ozone Season Group 2 allowances in a 
general account identified or established by the Administrator with the 
designated representative as the authorized account representative and 
with the owners and operators of such source (as indicated on the 
certificate of representation for the source) as the persons represented 
by the authorized account representative.
    (2)(i) After the Administrator has carried out the procedures set 
forth in paragraph (d)(1) of this section, upon any determination that 
would otherwise result in the initial recordation of a given number of 
CSAPR NOX Ozone Season Group 1 allowances in the compliance 
account for a source in a State listed in Sec. 52.38(b)(2)(iii) of this 
chapter (or Indian country within the borders of such a State), the 
Administrator will not record such CSAPR NOX Ozone Season 
Group 1 allowances but instead will allocate and record in such account 
an amount of CSAPR NOX Ozone Season Group 2 allowances for 
the control period in 2017 computed as the quotient, rounded up to the 
nearest allowance, of such given number of CSAPR NOX Ozone 
Season Group 1 allowances divided by the conversion factor determined 
under paragraph (d)(1)(ii) of this section.
    (ii) After the Administrator has carried out the procedures set 
forth in paragraph (d)(1) of this section and Sec. 97.826(d)(1), upon 
any determination that would otherwise result in the initial recordation 
of a given number of CSAPR NOX Ozone Season Group 1 
allowances in the compliance account for a source in a State listed in 
Sec. 52.38(b)(2)(v) of this chapter (or Indian country within the 
borders of such a State), the Administrator will not record such CSAPR 
NOX Ozone Season

[[Page 290]]

Group 1 allowances but instead will allocate and record in such account 
an amount of CSAPR NOX Ozone Season Group 3 allowances for 
the control period in 2021 computed as the quotient, rounded up to the 
nearest allowance, of such given number of CSAPR NOX Ozone 
Season Group 1 allowances divided by the conversion factor determined 
under paragraph (d)(1)(ii) of this section and further divided by the 
conversion factor determined under Sec. 97.826(d)(1)(i)(D).
    (e) Notwithstanding any other provision of this subpart or any SIP 
revision approved under Sec. 52.38(b)(4) or (5) of this chapter, CSAPR 
NOX Ozone Season Group 2 allowances or CSAPR NOX 
Ozone Season Group 3 allowances may be used to satisfy requirements to 
hold CSAPR NOX Ozone Season Group 1 allowances under this 
subpart as follows, provided that nothing in this paragraph alters the 
time as of which any such allowance holding requirement must be met or 
limits any consequence of a failure to timely meet any such allowance 
holding requirement:
    (1) After the Administrator has carried out the procedures set forth 
in paragraph (d)(1) of this section, the owner or operator of a CSAPR 
NOX Ozone Season Group 1 source in a State listed in Sec. 
52.38(b)(2)(ii) of this chapter (or Indian country within the borders of 
such a State) may satisfy a requirement to hold a given number of CSAPR 
NOX Ozone Season Group 1 allowances for the control period in 
2015 or 2016 by holding instead, in a general account established for 
this sole purpose, an amount of CSAPR NOX Ozone Season Group 
2 allowances for the control period in 2017 (or any later control period 
for which the allowance transfer deadline defined in Sec. 97.802 has 
passed) computed as the quotient, rounded up to the nearest allowance, 
of such given number of CSAPR NOX Ozone Season Group 1 
allowances divided by the conversion factor determined under paragraph 
(d)(1)(ii) of this section.
    (2) After the Administrator has carried out the procedures set forth 
in paragraph (d)(1) of this section and Sec. 97.826(d)(1), the owner or 
operator of a CSAPR NOX Ozone Season Group 1 source in a 
State listed in Sec. 52.38(b)(2)(iv) of this chapter (or Indian country 
within the borders of such a State) may satisfy a requirement to hold a 
given number of CSAPR NOX Ozone Season Group 1 allowances for 
the control period in 2015 or 2016 by holding instead, in a general 
account established for this sole purpose, an amount of CSAPR 
NOX Ozone Season Group 3 allowances for the control period in 
2021 (or any later control period for which the allowance transfer 
deadline defined in Sec. 97.1002 has passed) computed as the quotient, 
rounded up to the nearest allowance, of such given number of CSAPR 
NOX Ozone Season Group 1 allowances divided by the conversion 
factor determined under paragraph (d)(1)(ii) of this section and further 
divided by the conversion factor determined under Sec. 
97.826(d)(1)(i)(D).

this chapter or appendix B to part 75 of this chapter, the owner or 
operator shall recertify the monitoring system in accordance with Sec. 
75.20(b) of this chapter. Furthermore, whenever the owner or operator 
makes a replacement, modification, or change to the flue gas handling 
system or the unit's operation that may significantly change the stack 
flow or concentration profile, the owner or operator shall recertify 
each continuous emission monitoring system whose accuracy is potentially 
affected by the change, in accordance with Sec. 75.20(b) of this 
chapter. Examples of changes to a continuous emission monitoring system 
that require recertification include replacement of the analyzer, 
complete replacement of an existing continuous emission monitoring 
system, or change in location or orientation of the sampling probe or 
site. Any fuel flowmeter system, and any excepted NOX 
monitoring system under appendix E to part 75 of this chapter, under 
Sec. 97.530(a)(1) are subject to the recertification requirements in 
Sec. 75.20(g)(6) of this chapter.
    (3) Approval process for initial certification and recertification. 
For initial certification of a continuous monitoring system under Sec. 
97.530(a)(1), paragraphs (d)(3)(i) through (v) of this section apply. 
For recertifications of such monitoring systems, paragraphs (d)(3)(i) 
through (iv) of this section and the procedures in Sec. 75.20(b)(5) and 
(g)(7) of this chapter (in lieu of the procedures in paragraph (d)(3)(v) 
of this section) apply, provided that in applying paragraphs (d)(3)(i) 
through (iv) of this section, the words ``certification'' and ``initial 
certification'' are replaced by the word ``recertification'' and the 
word ``certified'' is replaced by the word ``recertified''.
    (i) Notification of certification. The designated representative 
shall submit to the appropriate EPA Regional Office and the 
Administrator written notice of the dates of certification testing, in 
accordance with Sec. 97.533.
    (ii) Certification application. The designated representative shall 
submit to the Administrator a certification application for each 
monitoring system. A complete certification application shall include 
the information specified in Sec. 75.63 of this chapter.
    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CSAPR NOX Ozone Season Group 1 
Trading Program for a period not to exceed 120 days after receipt by the 
Administrator of the complete certification application for the 
monitoring system under paragraph (d)(3)(ii) of this section. Data 
measured and recorded by the provisionally certified monitoring system, 
in accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the Administrator does not 
invalidate the provisional certification by issuing a notice of 
disapproval within 120 days of the date of receipt of the complete 
certification application by the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within

[[Page 295]]

120 days of receipt of the complete certification application under 
paragraph (d)(3)(ii) of this section. In the event the Administrator 
does not issue such a notice within such 120-day period, each monitoring 
system that meets the applicable performance requirements of part 75 of 
this chapter and is included in the certification application will be 
deemed certified for use under the CSAPR NOX Ozone Season 
Group 1 Trading Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the designated 
representative must submit the additional information required to 
complete the certification application. If the designated representative 
does not comply with the notice of incompleteness by the specified date, 
then the Administrator may issue a notice of disapproval under paragraph 
(d)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter).
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.532(b).
    (v) Procedures for loss of certification. If the Administrator 
issues a notice of disapproval of a certification application under 
paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (d)(3)(iv)(D) of this section, 
then:
    (A) The owner or operator shall substitute the following values, for 
each disapproved monitoring system, for each hour of unit operation 
during the period of invalid data specified under Sec. 
75.20(a)(4)(iii), Sec. 75.20(g)(7), or Sec. 75.21(e) of this chapter 
and continuing until the applicable date and hour specified under Sec. 
75.20(a)(5)(i) or (g)(7) of this chapter:
    (1) For a disapproved NOX emission rate (i.e., 
NOX-diluent) system, the maximum potential NOX 
emission rate, as defined in Sec. 72.2 of this chapter.
    (2) For a disapproved NOX pollutant concentration monitor 
and disapproved flow monitor, respectively, the maximum potential

Sec. 97.532  Monitoring system out-of-control periods.

    (a) General provisions. Whenever any monitoring system fails to meet 
the quality-assurance and quality-control requirements or data 
validation requirements of part 75 of this chapter, data shall be 
substituted using the applicable missing data procedures in subpart D or 
subpart H of, or appendix D or appendix E to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.531 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.531 for 
each disapproved monitoring system.

Sec. 97.611  Timing requirements for CSAPR SO2 Group 1 allowance allocations.

    (a) Existing units. (1) CSAPR SO2 Group 1 allowances are 
allocated, for

[[Page 315]]

the control periods in 2015 and each year thereafter, as provided in a 
notice of data availability issued by the Administrator. Providing an 
allocation to a unit in such notice does not constitute a determination 
that the unit is a CSAPR SO2 Group 1 unit, and not providing 
an allocation to a unit in such notice does not constitute a 
determination that the unit is not a CSAPR SO2 Group 1 unit.
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting after 2014, 
during the control period in two consecutive years, such unit will not 
be allocated the CSAPR SO2 Group 1 allowances provided in 
such notice for the unit for the control periods in the fifth year after 
the first such year and in each year after that fifth year. All CSAPR 
SO2 Group 1 allowances that would otherwise have been 
allocated to such unit will be allocated to the new unit set-aside for 
the State where such unit is located and for the respective years 
involved. If such unit resumes operation, the Administrator will 
allocate CSAPR SO2 Group 1 allowances to the unit in 
accordance with paragraph (b) of this section.
    (b) New units--(1) New unit set-asides. (i)(A) By June 1 of each 
year from 2015 through 2020, the Administrator will calculate the CSAPR 
SO2 Group 1 allowance allocation to each CSAPR SO2 
Group 1 unit in a State, in accordance with Sec. 97.612(a)(2) through 
(7) and (12) and Sec. Sec. 97.606(b)(2) and 97.630 through 97.635, for 
the control period in the year of the applicable calculation deadline 
under this paragraph and will promulgate a notice of data availability 
of the results of the calculations.
    (B) By March 1, 2022 and March 1 of each year thereafter, the 
Administrator will calculate the CSAPR SO2 Group 1 allowance 
allocation to each CSAPR SO2 Group 1 unit in a State, in 
accordance with Sec. 97.612(a)(2) through (7), (10), and (12) and 
Sec. Sec. 97.606(b)(2) and 97.630 through 97.635, for the control 
period in the year before the year of the applicable calculation 
deadline under this paragraph and will promulgate a notice of data 
availability of the results of the calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(1)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(1)(i) of this 
section and shall be limited to addressing whether the calculations 
(including the identification of the CSAPR SO2 Group 1 units) 
are in accordance with the provisions referenced in paragraph 
(b)(1)(i)(A) or (B) of this section, as applicable.
    (B) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(1)(i)(A) or (B) of this section, as 
applicable. By August 1 immediately after the promulgation of each 
notice of data availability required in paragraph (b)(1)(i)(A) of this 
section, or by May 1 immediately after the promulgation of each notice 
of data availability required in paragraph (b)(1)(i)(B) of this section, 
the Administrator will promulgate a notice of data availability of the 
results of the calculations incorporating any adjustments that the 
Administrator determines to be necessary and the reasons for accepting 
or rejecting any objections submitted in accordance with paragraph 
(b)(1)(ii)(A) of this section.
    (iii) If the new unit set-aside for a control period before 2021 
contains any CSAPR SO2 Group 1 allowances that have not been 
allocated in the applicable notice of data availability required in 
paragraph (b)(1)(ii) of this section, the Administrator will promulgate, 
by December 15 immediately after such notice, a notice of data 
availability that identifies any CSAPR SO2 Group 1 units that 
commenced commercial operation during the period starting January 1 of 
the year before the year of such control period and ending November 30 
of the year of such control period.

97.606(b)(2) and 97.630 through 97.635. By February 15 immediately after 
the promulgation of each notice of data availability required in 
paragraph (b)(1)(iii) of this section, the Administrator will promulgate 
a notice of data availability of any adjustments of the identification 
of CSAPR SO2 Group 1 units that the Administrator determines 
to be necessary, the reasons for accepting or rejecting any objections 
submitted in accordance with paragraph (b)(1)(iv)(A) of this section, 
and the results of such calculations.
    (v) To the extent any CSAPR SO2 Group 1 allowances are 
added to the new unit set-aside after promulgation of each notice of 
data availability required in paragraph (b)(1)(iv) of this section for a 
control period before 2021, or in paragraph (b)(1)(ii) of this section 
for a control period in 2021 or thereafter, the Administrator will 
promulgate additional notices of data availability, as deemed

allocation to each CSAPR SO2 Group 1 unit in Indian country 
within the borders of a State, in accordance with Sec. 97.612(b)(2) 
through (7), (10), and (12) and Sec. Sec. 97.606(b)(2) and 97.630

Sec. 97.612  CSAPR SO2 Group 1 allowance allocations to new units.

    (a) Allocations from new unit set-asides. For each control period in 
2015 and thereafter and for the CSAPR SO2 Group 1 units in 
each State, the Administrator will allocate CSAPR SO2 Group 1 
allowances to the CSAPR SO2 Group 1 units as follows:
    (1) The CSAPR SO2 Group 1 allowances will be allocated to 
the following CSAPR SO2 Group 1 units, except as provided in 
paragraph (a)(10) of this section:
    (i) CSAPR SO2 Group 1 units that are not allocated an 
amount of CSAPR SO2 Group 1 allowances in the notice of data 
availability issued under Sec. 97.611(a)(1) and that have deadlines for 
certification of monitoring systems under Sec. 97.630(b) not later than 
December 31 of the year of the control period;
    (ii) CSAPR SO2 Group 1 units whose allocation of an 
amount of CSAPR SO2 Group 1 allowances for such control 
period in the notice of data availability issued under Sec. 
97.611(a)(1) is covered by Sec. 97.611(c)(2) or (3);
    (iii) CSAPR SO2 Group 1 units that are allocated an 
amount of CSAPR SO2 Group 1 allowances for such control 
period in the notice of data availability issued under Sec. 
97.611(a)(1), which allocation is terminated for such control period 
pursuant to Sec. 97.611(a)(2), and that operate during the control 
period immediately preceding such control period, for allocations for a 
control period before 2021, or that operate during such control period, 
for allocations for a control period in 2021 or thereafter; or
    (iv) For purposes of paragraph (a)(9) of this section, CSAPR 
SO2 Group 1 units under Sec. 97.611(c)(1)(ii) whose 
allocation of an amount of CSAPR SO2 Group 1 allowances for 
such control period in the notice of data availability issued under 
Sec. 97.611(b)(1)(ii)(B) is covered by Sec. 97.611(c)(2) or (3).
    (2) The Administrator will establish a separate new unit set-aside 
for the State for each such control period. Each such new unit set-aside 
will be allocated CSAPR SO2 Group 1 allowances in an amount 
equal to the applicable amount of tons of SO2 emissions as 
set forth in Sec. 97.610(a) and will be allocated additional CSAPR 
SO2 Group 1 allowances (if any) in accordance with Sec. 
97.611(a)(2) and (c)(5) and paragraph (b)(10) of this section.
    (3) The Administrator will determine, for each CSAPR SO2 
Group 1 unit described in paragraph (a)(1) of this section, an 
allocation of CSAPR SO2 Group 1 allowances for the latest of 
the following control periods and for each subsequent control period:
    (i) The control period in 2015;
    (ii)(A) The first control period after the control period in which 
the CSAPR SO2 Group 1 unit commences commercial operation, 
for allocations for a control period before 2021; or
    (B) The control period containing the deadline for certification of 
the CSAPR SO2 Group 1 unit's monitoring systems under Sec. 
97.630(b), for allocations for a control period in 2021 or thereafter;
    (iii) For a unit described in paragraph (a)(1)(ii) of this section, 
the first control period in which the CSAPR SO2 Group 1 unit 
operates in the State after operating in another jurisdiction and for 
which the unit is not already allocated one or more CSAPR SO2 
Group 1 allowances; and
    (iv) For a unit described in paragraph (a)(1)(iii) of this section, 
the first control period after the control period in which the unit 
resumes operation, for allocations for a control period before 2021, or 
the control period in which the unit resumes operation, for allocations 
for a control period in 2021 or thereafter.
    (4)(i) The allocation to each CSAPR SO2 Group 1 unit 
described in paragraphs (a)(1)(i) through (iii) of this section and for 
each control period described in paragraph (a)(3) of this section will 
be an amount equal to the unit's total tons of SO2 emissions 
during the immediately preceding control period, for allocations for a 
control period before 2021, or the unit's total tons

[[Page 320]]

of SO2 emissions during the control period, for allocations 
for a control period in 2021 or thereafter.
    (ii) The Administrator will adjust the allocation amount in 
paragraph (a)(4)(i) of this section in accordance with paragraphs (a)(5) 
through (7) and (12) of this section.
    (5) The Administrator will calculate the sum of the allocation 
amounts of CSAPR SO2 Group 1 allowances determined for all 
such CSAPR SO2 Group 1 units under paragraph (a)(4)(i) of 
this section in the State for such control period.
    (6) If the amount of CSAPR SO2 Group 1 allowances in the 
new unit set-aside for the State for such control period is greater than 
or equal to the sum under paragraph (a)(5) of this section, then the 
Administrator will allocate the amount of CSAPR SO2 Group 1 
allowances determined for each such CSAPR SO2 Group 1 unit 
under paragraph (a)(4)(i) of this section.
    (7) If the amount of CSAPR SO2 Group 1 allowances in the 
new unit set-aside for the State for such control period is less than 
the sum under paragraph (a)(5) of this section, then the Administrator 
will allocate to each such CSAPR SO2 Group 1 unit the amount 
of the CSAPR SO2 Group 1 allowances determined under 
paragraph (a)(4)(i) of this section for the unit, multiplied by the 
amount of CSAPR SO2 Group 1 allowances in the new unit set-
aside for such control period, divided by the sum under paragraph (a)(5) 
of this section, and rounded to the nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.611(b)(1)(i) and (ii), of the amount of CSAPR 
SO2 Group 1 allowances allocated under paragraphs (a)(2) 
through (7) and (12) of this section for such control period to each 
CSAPR SO2 Group 1 unit eligible for such allocation.
    (9) For a control period before 2021, if, after completion of the 
procedures under paragraphs (a)(5) through (8) of this section for such 
control period, any unallocated CSAPR SO2 Group 1 allowances 
remain in the new unit set-aside for the State for such control period, 
the Administrator will allocate such CSAPR SO2 Group 1 
allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (a)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such 
control period and ending November 30 of the year of such control 
period, the positive difference (if any) between the unit's emissions 
during such control period and the amount of CSAPR SO2 Group 
1 allowances referenced in the notice of data availability required 
under Sec. 97.611(b)(1)(ii) for the unit for such control period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (a)(9)(i) of this section;
    (iii) If the amount of unallocated CSAPR SO2 Group 1 
allowances remaining in the new unit set-aside for the State for such 
control period is greater than or equal to the sum determined under 
paragraph (a)(9)(ii) of this section, then the Administrator will 
allocate the amount of CSAPR SO2 Group 1 allowances 
determined for each such CSAPR SO2 Group 1 unit under 
paragraph (a)(9)(i) of this section; and
    (iv) If the amount of unallocated CSAPR SO2 Group 1 
allowances remaining in the new unit set-aside for the State for such 
control period is less than the sum under paragraph (a)(9)(ii) of this 
section, then the Administrator will allocate to each such CSAPR 
SO2 Group 1 unit the amount of the CSAPR SO2 Group 
1 allowances determined under paragraph (a)(9)(i) of this section for 
the unit, multiplied by the amount of unallocated CSAPR SO2 
Group 1 allowances remaining in the new unit set-aside for such control 
period, divided by the sum under paragraph (a)(9)(ii) of this section, 
and rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (a)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (a)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR SO2 Group 
1 allowances remain in the new unit set-

[[Page 321]]

aside for the State for such control period, the Administrator will 
allocate to each CSAPR SO2 Group 1 unit that is in the State, 
is allocated an amount of CSAPR SO2 Group 1 allowances in the 
notice of data availability issued under Sec. 97.611(a)(1), and 
continues to be allocated CSAPR SO2 Group 1 allowances for 
such control period in accordance with Sec. 97.611(a)(2), an amount of 
CSAPR SO2 Group 1 allowances equal to the following: The 
total amount of such remaining unallocated CSAPR SO2 Group 1 
allowances in such new unit set-aside, multiplied by the unit's 
allocation under Sec. 97.611(a) for such control period, divided by the 
remainder of the amount of tons in the applicable State SO2 
Group 1 trading budget minus the sum of the amounts of tons in such new 
unit set-aside and the Indian country new unit set-aside for the State 
for such control period, and rounded to the nearest allowance.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.611(b)(1)(iii), (iv), and (v), of the 
amount of CSAPR SO2 Group 1 allowances allocated under 
paragraphs (a)(9), (10), and (12) of this section for such control 
period to each CSAPR SO2 Group 1 unit eligible for such 
allocation.
    (ii) For a control period in 2021 or thereafter, the Administrator 
will notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.611(b)(1)(i), (ii), and (v), of the 
amount of CSAPR SO2 Group 1 allowances allocated under 
paragraphs (a)(2) through (7), (10), and (12) of this section for such 
control period to each CSAPR SO2 Group 1 unit eligible for 
such allocation.
    (12) Notwithstanding the requirements of paragraphs (a)(2) through 
(11) of this section, if the calculations of allocations from a new unit 
set-aside for a control period before 2021 under paragraph (a)(7) of 
this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or 
paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a 
control period in 2021 or thereafter under paragraph (a)(7) of this 
section or paragraphs (a)(6) and (10) of this section, would otherwise 
result in total allocations from such new unit set-aside unequal to the 
total amount of such new unit set-aside, then the Administrator will 
adjust the results of such calculations as follows. The Administrator 
will list the CSAPR SO2 Group 1 units in descending order 
based on such units' allocation amounts under paragraph (a)(7), 
(a)(9)(iv), or (a)(10) of this section, as applicable, and, in cases of 
equal allocation amounts, in alphabetical order of the relevant sources' 
names and numerical order of the relevant units' identification numbers, 
and will adjust each unit's allocation amount under such paragraph 
upward or downward by one CSAPR SO2 Group 1 allowance (but 
not below zero) in the order in which the units are listed, and will 
repeat this adjustment process as necessary, until the total allocations 
from such new unit set-aside equal the total amount of such new unit 
set-aside.
    (b) Allocations from Indian country new unit set-asides. For each 
control period in 2015 and thereafter and for the CSAPR SO2 
Group 1 units in Indian country within the borders of each State, the 
Administrator will allocate CSAPR SO2 Group 1 allowances to 
the CSAPR SO2 Group 1 units as follows:
    (1) The CSAPR SO2 Group 1 allowances will be allocated to 
the following CSAPR SO2 Group 1 units, except as provided in 
paragraph (b)(10) of this section:
    (i) CSAPR SO2 Group 1 units that are not allocated an 
amount of CSAPR SO2 Group 1 allowances in the notice of data 
availability issued under Sec. 97.611(a)(1) and that have deadlines for 
certification of monitoring systems under Sec. 97.630(b) not later than 
December 31 of the year of the control period; or
    (ii) For purposes of paragraph (b)(9) of this section, CSAPR 
SO2 Group 1 units under Sec. 97.611(c)(1)(ii) whose 
allocation of an amount of CSAPR SO2 Group 1 allowances for 
such control period in the notice of data availability issued under 
Sec. 97.611(b)(2)(ii)(B) is covered by Sec. 97.611(c)(2) or (3).
    (2) The Administrator will establish a separate Indian country new 
unit set-aside for the State for each such control period. Each such 
Indian country new unit set-aside will be allocated

[[Page 322]]

CSAPR SO2 Group 1 allowances in an amount equal to the 
applicable amount of tons of SO2 emissions as set forth in 
Sec. 97.610(a) and will be allocated additional CSAPR SO2 
Group 1 allowances (if any) in accordance with Sec. 97.611(c)(5).
    (3) The Administrator will determine, for each CSAPR SO2 
Group 1 unit described in paragraph (b)(1) of this section, an 
allocation of CSAPR SO2 Group 1 allowances for the later of 
the following control periods and for each subsequent control period:
    (i) The control period in 2015; and

equal to the unit's total tons of SO2 emissions during the 
immediately preceding control period, for allocations for a control 
period before 2021, or the unit's total tons of SO2 emissions 
during the control period, for allocations for a control period in 2021 
or thereafter.
    (ii) The Administrator will adjust the allocation amount in 
paragraph (b)(4)(i) of this section in accordance with paragraphs (b)(5) 
through (7) and (12) of this section.
    (5) The Administrator will calculate the sum of the allocation 
amounts of CSAPR SO2 Group 1 allowances determined for all 
such CSAPR SO2 Group 1 units under paragraph (b)(4)(i) of 
this section in Indian country within the borders of the State for such 
control period.
    (6) If the amount of CSAPR SO2 Group 1 allowances in the 
Indian country new unit set-aside for the State for such control period 
is greater than or equal to the sum under paragraph (b)(5) of this 
section, then the Administrator will allocate the amount of CSAPR 
SO2 Group 1 allowances determined for each such CSAPR 
SO2 Group 1 unit under paragraph (b)(4)(i) of this section.
    (7) If the amount of CSAPR SO2 Group 1 allowances in the 
Indian country new unit set-aside for the State for such control period 
is less than the sum under paragraph (b)(5) of this section, then the 
Administrator will allocate to each such CSAPR SO2 Group 1

determined under paragraph (b)(4)(i) of this section for the unit, 
multiplied by the amount of CSAPR SO2 Group 1 allowances in 
the Indian country new unit set-aside for such control period, divided 
by the sum under paragraph (b)(5) of this section, and rounded to the 
nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.611(b)(2)(i) and (ii), of the amount of CSAPR 
SO2 Group 1 allowances allocated under paragraphs (b)(2) 
through (7) and (12) of this section for such control period to each 
CSAPR SO2 Group 1 unit eligible for such allocation.
    (9) For a control period before 2021, if, after completion of the 
procedures under paragraphs (b)(5) through (8) of this section for such 
control period, any unallocated CSAPR SO2 Group 1 allowances 
remain in the Indian country new unit set-aside for the State for such 
control period, the Administrator will allocate such CSAPR 
SO2 Group 1 allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (b)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such 
control period and ending November 30 of the year of such control 
period, the positive difference (if any) between the unit's emissions 
during such control period and the amount of CSAPR SO2 Group 
1 allowances referenced in the notice of data availability required 
under Sec. 97.611(b)(2)(ii) for the unit for such control period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (b)(9)(i) of this section;

[[Page 323]]

    (iii) If the amount of unallocated CSAPR SO2 Group 1 
allowances remaining in the Indian country new unit set-aside for the 
State for such control period is greater than or equal to the sum 
determined under paragraph (b)(9)(ii) of this section, then the 
Administrator will allocate the amount of CSAPR SO2 Group 1 
allowances determined for each such CSAPR SO2 Group 1 unit 
under paragraph (b)(9)(i) of this section; and
    (iv) If the amount of unallocated CSAPR SO2 Group 1 
allowances remaining in the Indian country new unit set-aside for the 
State for such control period is less than the sum under paragraph 
(b)(9)(ii) of this section, then the Administrator will allocate to each 
such CSAPR SO2 Group 1 unit the amount of the CSAPR 
SO2 Group 1 allowances determined under paragraph (b)(9)(i) 
of this section for the unit, multiplied by the amount of unallocated 
CSAPR SO2 Group 1 allowances remaining in the Indian country 
new unit set-aside for such control period, divided by the sum under 
paragraph (b)(9)(ii) of this section, and rounded to the nearest 
allowance.
    (10) If, after completion of the procedures under paragraphs (b)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (b)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR SO2 Group 
1 allowances remain in the Indian country new unit set-aside for the 
State for such control period, the Administrator will:
    (i) Transfer such unallocated CSAPR SO2 Group 1 
allowances to the new unit set-aside for the State for such control 
period; or
    (ii) If the State has a SIP revision approved under Sec. 52.39(e) 
or (f) of this chapter covering such control period, include such 
unallocated CSAPR SO2 Group 1 allowances in the portion of 
the State SO2 Group 1 trading budget that may be allocated 
for such control period in accordance with such SIP revision.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.611(b)(2)(iii), (iv), and (v), of the 
amount of CSAPR SO2 Group 1 allowances allocated under 
paragraphs (b)(9), (10), and (12) of this section for such control 
period to each CSAPR SO2 Group 1 unit eligible for such 
allocation.
    (ii) For a control period in 2021 or thereafter, the Administrator 
will notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.611(b)(2)(i), (ii), and (v), of the 
amount of CSAPR SO2 Group 1 allowances allocated under 
paragraphs (b)(2) through (7), (10), and (12) of this section for such 
control period to each CSAPR SO2 Group 1 unit eligible for 
such allocation.
    (12) Notwithstanding the requirements of paragraphs (b)(2) through 
(11) of this section, if the calculations of allocations from an Indian 
country new unit set-aside for a control period before 2021 under 
paragraph (b)(7) of this section or paragraphs (b)(6) and (b)(9)(iv) of 
this section, or for a control period in 2021 or thereafter under 
paragraph (b)(7) of this section, would otherwise result in total 
allocations from such Indian country new unit set-aside unequal to the 
total amount of such Indian country new unit set-aside, then the 
Administrator will adjust the results of such calculations as follows. 
The Administrator will list the CSAPR SO2 Group 1 units in 
descending order based on such units' allocation amounts under paragraph

Sec. 97.624  Compliance with CSAPR SO2 Group 1 emissions limitation.

    (a) Availability for deduction for compliance. CSAPR SO2 
Group 1 allowances are available to be deducted for compliance with a 
source's CSAPR SO2 Group 1 emissions limitation for a control 
period in a given year only if the CSAPR SO2 Group 1 
allowances:
    (1) Were allocated or auctioned for such control period or a control 
period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance 
transfer deadline for such control period.
    (b) Deductions for compliance. After the recordation, in accordance 
with Sec. 97.623, of CSAPR SO2 Group 1 allowance transfers 
submitted by the allowance transfer deadline for a control period in a 
given year, the Administrator will deduct from each source's compliance 
account CSAPR SO2 Group 1 allowances available under 
paragraph (a) of this section in order to determine whether the source 
meets the CSAPR SO2 Group 1 emissions limitation for such 
control period, as follows:
    (1) Until the amount of CSAPR SO2 Group 1 allowances 
deducted equals the number of tons of total SO2 emissions 
from all CSAPR SO2 Group 1 units at the source for such 
control period; or
    (2) If there are insufficient CSAPR SO2 Group 1 
allowances to complete the deductions in paragraph (b)(1) of this 
section, until no more CSAPR SO2 Group 1 allowances available 
under paragraph (a) of this section remain in the compliance account.
    (c) Selection of CSAPR SO2 Group 1 allowances for deduction--(1) 
Identification by serial number. The designated representative for a 
source may request that specific CSAPR SO2 Group 1 
allowances, identified by serial number, in the source's compliance 
account be deducted for emissions or excess emissions for a control 
period in a given year in accordance with paragraph (b) or (d) of this 
section. In order to be complete, such request shall be submitted to the 
Administrator by the allowance transfer deadline for such control period 
and include, in a format prescribed by the Administrator, the 
identification of the CSAPR SO2 Group 1 source and the 
appropriate serial numbers.
    (2) First-in, first-out. The Administrator will deduct CSAPR 
SO2 Group 1 allowances under paragraph (b) or (d) of this 
section from the source's compliance account in accordance with a 
complete request under paragraph (c)(1) of this section or, in the 
absence of such request or in the case of identification of an 
insufficient amount of CSAPR SO2 Group 1 allowances in such 
request, on a first-in, first-out accounting basis in the following 
order:
    (i) Any CSAPR SO2 Group 1 allowances that were recorded 
in the compliance account pursuant to Sec. 97.621 and not transferred 
out of the compliance account, in the order of recordation; and then
    (ii) Any other CSAPR SO2 Group 1 allowances that were 
transferred to and recorded in the compliance account pursuant to this 
subpart, in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the CSAPR SO2 Group 1 source has excess 
emissions, the Administrator will deduct from the source's compliance 
account an amount of CSAPR SO2 Group 1 allowances, allocated 
or auctioned for a control period in a prior year or the control period 
in the year of the excess emissions or in the immediately following 
year, equal to two times the number of tons of the source's excess 
emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

    (1) Were allocated or auctioned for a control period in a prior year 
or the control period in the given year or in the immediately following 
year; and
    (2) Are held in the assurance account, established by the

    (1) By June 1 of each year from 2018 through 2021 and August 1 of 
each year thereafter, the Administrator will:
    (i) Calculate, for each State (and Indian country within the borders 
of such State), the total SO2 emissions from all CSAPR 
SO2 Group 1 units at CSAPR SO2 Group 1 sources in 
the State (and Indian country within the borders of such State) during 
the control period in the year before the year of this calculation 
deadline and the amount, if any, by which such total SO2 
emissions exceed the State assurance level as described in Sec. 
97.606(c)(2)(iii); and
    (ii) For the set of any States (and Indian country within the 
borders of such States) for which the results of the calculations 
required in paragraph (b)(1)(i) of this section indicate that total

for such control period--
    (A) Calculate, for each such State (and Indian country within the 
borders of such State) and such control period and each common 
designated representative for such control period for a group of one or 
more CSAPR SO2 Group 1 sources and units in such State (and 
such Indian country), the common designated representative's share of 
the total SO2 emissions from all CSAPR SO2 Group 1 
units at CSAPR SO2 Group 1 sources in such State (and such 
Indian country), the common designated representative's assurance level, 
and the amount (if any) of CSAPR SO2 Group 1 allowances that 
the owners and operators of such group of sources and units must hold in 
accordance with the calculation formula in Sec. 97.606(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the SO2 emissions 
from each CSAPR SO2 Group 1 source in each such State (and 
Indian country within the borders of such State).
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.606(c)(2)(iii), Sec. Sec. 97.606(b) and 97.630 through 97.635, the 
definitions of ``common designated representative'', ``common designated 
representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.602, and the calculation formula in 
Sec. 97.606(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1

calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) For any State (and Indian country within the borders of such 
State) referenced in each notice of data availability required in 
paragraph (b)(2)(ii) of this section as having CSAPR SO2 
Group 1 units with total SO2 emissions exceeding the State 
assurance level for

[[Page 337]]

a control period in a given year, the Administrator will establish one 
assurance account for each set of owners and operators referenced, in 
the notice of data availability required under paragraph (b)(2)(ii) of 
this section, as all of the owners and operators of a group of CSAPR 
SO2 Group 1 sources and units in the State (and Indian 
country within the borders of such State) having a common designated 
representative for such control period and as being required to hold 
CSAPR SO2 Group 1 allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate CSAPR SO2 Group 
1 sources, CSAPR SO2 Group 1 units, and State (and Indian 
country within the borders of such State) under paragraph (b)(3) of this 
section a total amount of CSAPR SO2 Group 1 allowances, 
available for deduction under paragraph (a) of this section, equal to 
the amount such owners and operators are required to hold with regard to 
such sources, units and State (and Indian country within the borders of 
such State) as calculated by the Administrator and referenced in such 
notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.623, of CSAPR 
SO2 Group 1 allowance transfers submitted by midnight of such 
date, the Administrator will determine whether the owners and operators 
described in paragraph (b)(3) of this section hold, in the assurance 
account for the appropriate CSAPR SO2 Group 1 sources, CSAPR 
SO2 Group 1 units, and State (and Indian country within the 
borders of such State) established under paragraph (b)(3) of this 
section, the amount of CSAPR SO2 Group 1 allowances available 
under paragraph (a) of this section that the owners and operators are 
required to hold with regard to such sources, units, and State (and 
Indian country within the borders of such State) as calculated by the 
Administrator and referenced in the notice required in paragraph 
(b)(2)(ii) of this section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR SO2 Group 1 allowances that the owners and 
operators are required to hold in accordance with Sec. 97.606(c)(2)(i) 
for such control period shall continue to be such amounts as calculated 
by the Administrator and referenced in such notice required in paragraph 
(b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator will use the 
data as so revised to recalculate the amounts of CSAPR SO2 
Group 1 allowances that owners and operators are required to hold in 
accordance with the calculation formula in Sec. 97.606(c)(2)(i) for 
such control period with regard to the CSAPR SO2 Group 1 
sources, CSAPR SO2 Group 1 units, and State (and Indian 
country within the borders of such State) involved, provided that such 
litigation under part 78 of this chapter, or the proceeding under part 
78 of this chapter that resulted in the decision appealed in such 
litigation under section 307 of the Clean Air Act, was initiated no 
later than 30 days after promulgation of such notice required in

    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of CSAPR 
SO2 Group 1 allowances that the owners and operators are 
required to hold for such control period with regard to the CSAPR 
SO2 Group 1 sources, CSAPR SO2 Group 1 units, and 
State (and Indian country within the borders of such State) involved--
    (A) Where the amount of CSAPR SO2 Group 1 allowances that 
the owners and operators are required to hold increases as a result of 
the use of all such revised data, the Administrator will establish a 
new, reasonable deadline on which the owners and operators shall hold 
the additional amount of CSAPR SO2 Group 1 allowances in the 
assurance account established by the Administrator for the appropriate 
CSAPR SO2 Group 1 sources, CSAPR SO2 Group 1 
units, and State (and Indian country within the borders of such State) 
under paragraph (b)(3) of this section. The owners' and operators' 
failure to hold such additional amount, as required, before the new 
deadline shall not be a violation of the Clean Air Act. The owners' and 
operators' failure to hold such additional amount, as required, as of 
the new deadline shall be a violation of the Clean Air Act. Each CSAPR 
SO2 Group 1 allowance that the owners and operators fail to 
hold as required as of the new deadline, and each day in such control 
period, shall be a separate violation of the Clean Air Act.
    (B) For the owners and operators for which the amount of CSAPR 
SO2 Group 1 allowances required to be held decreases as a 
result of the use of all such revised data, the Administrator will 
record, in all accounts from which CSAPR SO2 Group 1 
allowances were transferred by such owners and operators for such 
control period to the assurance account established by the Administrator 
for the appropriate CSAPR SO2 Group 1 sources, CSAPR 
SO2 Group 1 units, and State (and Indian country within the 
borders of such State) under paragraph (b)(3) of this section, a total 
amount of the CSAPR SO2 Group 1 allowances held in such 
assurance account equal to the amount of the decrease. If CSAPR 
SO2 Group 1 allowances were transferred to such assurance 
account from more than one account, the amount of CSAPR SO2 
Group 1 allowances recorded in each such transferor account will be in 
proportion to the percentage of the total amount of CSAPR SO2 
Group 1 allowances transferred to such assurance account for such 
control period from such transferor account.
    (C) Each CSAPR SO2 Group 1 allowance held under paragraph 
(b)(6)(iii)(A) of this section as a result of recalculation of 
requirements under the CSAPR SO2 Group 1 assurance provisions 
for such control period must be a CSAPR SO2 Group 1 allowance 
allocated for a control period in a year before or the year immediately 
following, or in the same year as, the year of such control period.

(g)(7) of this chapter (in lieu of the procedures in paragraph (d)(3)(v) 
of this section) apply, provided that in applying paragraphs (d)(3)(i) 
through (iv) of this section, the words ``certification'' and ``initial 
certification'' are replaced by the word ``recertification'' and the 
word ``certified'' is replaced by the word ``recertified''.
    (i) Notification of certification. The designated representative 
shall submit to the appropriate EPA Regional Office

[[Page 342]]

and the Administrator written notice of the dates of certification 
testing, in accordance with Sec. 97.633.
    (ii) Certification application. The designated representative shall 
submit to the Administrator a certification application for each 
monitoring system. A complete certification application shall include 
the information specified in Sec. 75.63 of this chapter.
    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CSAPR SO2 Group 1 Trading 
Program for a period not to exceed 120 days after receipt by the 
Administrator of the complete certification application for the 
monitoring system under paragraph (d)(3)(ii) of this section. Data 
measured and recorded by the provisionally certified monitoring system, 
in accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the Administrator does not 
invalidate the provisional certification by issuing a notice of 
disapproval within 120 days of the date of receipt of the complete 
certification application by the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph 
(d)(3)(ii) of this section. In the event the Administrator does not 
issue such a notice within such 120-day period, each monitoring system 
that meets the applicable performance requirements of part 75 of this 
chapter and is included in the certification application will be deemed 
certified for use under the CSAPR SO2 Group 1 Trading 
Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the designated 
representative must submit the additional information required to 
complete the certification application. If the designated representative 
does not comply with the notice of incompleteness by the specified date, 
then the Administrator may issue a notice of disapproval under paragraph 
(d)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter).
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.632(b).
    (v) Procedures for loss of certification. If the Administrator 
issues a notice of disapproval of a certification application under 
paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (d)(3)(iv)(D) of this section, 
then:
    (A) The owner or operator shall substitute the following values, for 
each disapproved monitoring system, for each hour of unit operation 
during the period of invalid data specified under Sec. 
75.20(a)(4)(iii), Sec. 75.20(g)(7), or Sec. 75.21(e) of this chapter 
and continuing until the applicable date and hour specified under Sec. 
75.20(a)(5)(i) or (g)(7) of this chapter:
    (1) For a disapproved SO2 pollutant concentration monitor 
and disapproved

Sec. 97.632  Monitoring system out-of-control periods.

    (a) General provisions. Whenever any monitoring system fails to meet 
the quality-assurance and quality-control requirements or data 
validation requirements of part 75 of this chapter, data shall be 
substituted using the applicable missing data procedures in subpart D 
of, or appendix D to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.631 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.631 for 
each disapproved monitoring system.

Sec. 97.711  Timing requirements for CSAPR SO2 Group 2 allowance allocations.

    (a) Existing units. (1) CSAPR SO2 Group 2 allowances are 
allocated, for the control periods in 2015 and each year thereafter, as 
provided in a notice of data availability issued by the Administrator. 
Providing an allocation to a unit in such notice does not constitute a 
determination that the unit is a CSAPR SO2 Group 2 unit, and 
not providing an allocation to a unit in such notice does not constitute 
a determination that the unit is not a CSAPR SO2 Group 2 
unit.
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting

[[Page 361]]

after 2014, during the control period in two consecutive years, such 
unit will not be allocated the CSAPR SO2 Group 2 allowances 
provided in such notice for the unit for the control periods in the 
fifth year after the first such year and in each year after that fifth 
year. All CSAPR SO2 Group 2 allowances that would otherwise 
have been allocated to such unit will be allocated to the new unit set-
aside for the State where such unit is located and for the respective 
years involved. If such unit resumes operation, the Administrator will 
allocate CSAPR SO2 Group 2 allowances to the unit in 
accordance with paragraph (b) of this section.

Sec. Sec. 97.706(b)(2) and 97.730 through 97.735, for the control 
period in the year before the year of the applicable calculation 
deadline under this paragraph and will promulgate a notice of data 
availability of the results of the calculations.

(b)(1)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(1)(i) of this 
section and shall be limited to addressing whether the calculations

section, or by May 1 immediately after the promulgation of each notice 
of data availability required in paragraph (b)(1)(i)(B) of this section, 
the Administrator will promulgate a notice of data availability of the 
results of the calculations incorporating any adjustments that the 
Administrator determines to be necessary and the reasons for accepting 
or rejecting any objections submitted in accordance with paragraph 
(b)(1)(ii)(A) of this section.
    (iii) If the new unit set-aside for a control period before 2021 
contains any CSAPR SO2 Group 2 allowances that have not been 
allocated in the applicable notice of data availability required in 
paragraph (b)(1)(ii) of this section, the Administrator will promulgate, 
by December 15 immediately after such notice, a notice of data 
availability that identifies any CSAPR SO2 Group 2 units that 
commenced commercial operation during the period starting January 1 of 
the year before the year of such control period and ending November 30 
of the year of such control period.
    (iv) For each notice of data availability required in paragraph

added to the new unit set-aside after promulgation of each notice of 
data availability required in paragraph (b)(1)(iv) of this section for a 
control period before 2021, or in paragraph (b)(1)(ii) of this section 
for a control period in 2021 or thereafter, the Administrator will

of this section, then the Administrator will notify the designated 
representative of the recipient and will act in accordance with the 
procedures set forth in paragraphs (c)(2) through (5) of this section:
    (i)(A) The recipient is not actually a CSAPR SO2 Group 2 
unit under Sec. 97.704 as of January 1, 2015 and is allocated CSAPR 
SO2 Group 2 allowances for such control period or, in the 
case of an allocation under a provision of a SIP revision approved under 
Sec. 52.39(g), (h), or (i) of this chapter, the recipient is not 
actually a CSAPR SO2 Group 2 unit as of January 1, 2015 and

period in the State from whose SO2 Group 2 trading budget the 
CSAPR SO2 Group 2 allowances allocated under paragraph (a) of 
this section, or under a provision of a SIP revision approved under 
Sec. 52.39(g), (h), or (i) of this chapter, were allocated for such 
control period.
    (ii) The recipient is not actually a CSAPR SO2 Group 2 
unit under Sec. 97.704 as of January 1 of such control period and is 
allocated CSAPR SO2 Group 2 allowances for such control 
period or, in the case of an allocation under a provision of a SIP 
revision approved under Sec. 52.39(h) or (i) of this chapter, the 
recipient is not actually a CSAPR SO2 Group 2 unit as of 
January 1 of such control period and is allocated CSAPR SO2 
Group 2 allowances for such control period that the SIP revision 
provides should be allocated only to recipients that are CSAPR 
SO2 Group 2 units as of January 1 of such control period.

[[Page 364]]

    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such CSAPR SO2 Group 2 
allowances under Sec. 97.721.
    (3) If the Administrator already recorded such CSAPR SO2 
Group 2 allowances under Sec. 97.721 and if the Administrator makes the 
determination under paragraph (c)(1) of this section before making 
deductions for the source that includes such recipient under Sec. 
97.724(b) for such control period, then the Administrator will deduct 
from the account in which such CSAPR SO2 Group 2 allowances 
were recorded an amount of CSAPR SO2 Group 2 allowances 
allocated for the same or a prior control period equal to the amount of 
such already recorded CSAPR SO2 Group 2 allowances. The 
authorized account representative shall ensure that there are sufficient 
CSAPR SO2 Group 2 allowances in such account for completion 
of the deduction.
    (4) If the Administrator already recorded such CSAPR SO2 
Group 2 allowances under Sec. 97.721 and if the Administrator makes the 
determination under paragraph (c)(1) of this section after making 
deductions for the source that includes such recipient under Sec. 
97.724(b) for such control period, then the Administrator will not make 
any deduction to take account of such already recorded CSAPR 
SO2 Group 2 allowances.
    (5)(i) With regard to the CSAPR SO2 Group 2 allowances 
that are not recorded, or that are deducted as an incorrect allocation, 
in accordance with paragraphs (c)(2) and (3) of this section for a 
recipient under paragraph (c)(1)(i) of this section, the Administrator 
will:
    (A) Transfer such CSAPR SO2 Group 2 allowances to the new

    (4)(i) The allocation to each CSAPR SO2 Group 2 unit 
described in paragraphs (a)(1)(i) through (iii) of this section and for 
each control period described in paragraph (a)(3) of this section will 
be an amount equal to the unit's total tons of SO2 emissions 
during the immediately preceding control period, for allocations for a 
control period before 2021, or the unit's total tons of SO2 
emissions during the control period, for allocations for a control 
period in 2021 or thereafter.

amounts of CSAPR SO2 Group 2 allowances determined for all 
such CSAPR SO2 Group 2 units under paragraph (a)(4)(i) of 
this

[[Page 366]]

section in the State for such control period.
    (6) If the amount of CSAPR SO2 Group 2 allowances in the 
new unit set-aside for the State for such control period is greater than 
or equal to the sum under paragraph (a)(5) of this section, then the 
Administrator will allocate the amount of CSAPR SO2 Group 2 
allowances determined for each such CSAPR SO2 Group 2 unit 
under paragraph (a)(4)(i) of this section.
    (7) If the amount of CSAPR SO2 Group 2 allowances in the 
new unit set-aside for the State for such control period is less than 
the sum under paragraph (a)(5) of this section, then the Administrator 
will allocate to each such CSAPR SO2 Group 2 unit the amount 
of the CSAPR SO2 Group 2 allowances determined under 
paragraph (a)(4)(i) of this section for the unit, multiplied by the 
amount of CSAPR SO2 Group 2 allowances in the new unit set-
aside for such control period, divided by the sum under paragraph (a)(5) 
of this section, and rounded to the nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.711(b)(1)(i) and (ii), of the amount of CSAPR 
SO2 Group 2 allowances allocated under paragraphs (a)(2)

remain in the new unit set-aside for the State for such control period, 
the Administrator will allocate such CSAPR SO2 Group 2 
allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (a)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such 
control period and ending November 30 of the year of such control 
period, the positive difference (if any) between the unit's emissions 
during such control period and the amount of CSAPR SO2 Group 
2 allowances referenced in the notice of data availability required 
under Sec. 97.711(b)(1)(ii) for the unit for such control period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (a)(9)(i) of this section;
    (iii) If the amount of unallocated CSAPR SO2 Group 2 
allowances remaining in the new unit set-aside for the State for such 
control period is greater than or equal to the sum determined under 
paragraph (a)(9)(ii) of this section, then the Administrator will 
allocate the amount of CSAPR SO2 Group 2 allowances 
determined for each such CSAPR SO2 Group 2 unit under 
paragraph (a)(9)(i) of this section; and
    (iv) If the amount of unallocated CSAPR SO2 Group 2 
allowances remaining in the new unit set-aside for the State for such 
control period is less than the sum under paragraph (a)(9)(ii) of this 
section, then the Administrator will allocate to each such CSAPR 
SO2 Group 2 unit the amount of the CSAPR SO2 Group 
2 allowances determined under paragraph (a)(9)(i) of this section for 
the unit, multiplied by the amount of unallocated CSAPR SO2 
Group 2 allowances remaining in the new unit set-aside for such control 
period, divided by the sum under paragraph (a)(9)(ii) of this section, 
and rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (a)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (a)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR SO2 Group 
2 allowances remain in the new unit set-aside for the State for such 
control period, the Administrator will allocate to each CSAPR 
SO2 Group 2 unit that is in the State, is allocated an amount 
of CSAPR SO2 Group 2 allowances in the notice of data 
availability issued under Sec. 97.711(a)(1), and continues to be 
allocated CSAPR SO2 Group 2 allowances for such control 
period in accordance with Sec. 97.711(a)(2), an amount of CSAPR 
SO2 Group 2 allowances equal to the following: The total 
amount of such remaining unallocated CSAPR SO2 Group 2 
allowances in such new unit set-aside,

[[Page 367]]

multiplied by the unit's allocation under Sec. 97.711(a) for such 
control period, divided by the remainder of the amount of tons in the 
applicable State SO2 Group 2 trading budget minus the sum of 
the amounts of tons in such new unit set-aside and the Indian country 
new unit set-aside for the State for such control period, and rounded to 
the nearest allowance.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.711(b)(1)(iii), (iv), and (v), of the

amount of CSAPR SO2 Group 2 allowances allocated under 
paragraphs (a)(2) through (7), (10), and (12) of this section for such 
control period to each CSAPR SO2 Group 2 unit eligible for 
such allocation.
    (12) Notwithstanding the requirements of paragraphs (a)(2) through 
(11) of this section, if the calculations of allocations from a new unit 
set-aside for a control period before 2021 under paragraph (a)(7) of 
this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or 
paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a 
control period in 2021 or thereafter under paragraph (a)(7) of this 
section or paragraphs (a)(6) and (10) of this section, would otherwise 
result in total allocations from such new unit set-aside unequal to the 
total amount of such new unit set-aside, then the Administrator will 
adjust the results of such calculations as follows. The Administrator 
will list the CSAPR SO2 Group 2 units in descending order 
based on such units' allocation amounts under paragraph (a)(7), 
(a)(9)(iv), or (a)(10) of this section, as applicable, and, in cases of 
equal allocation amounts, in alphabetical order of the relevant sources' 
names and numerical order of the relevant units' identification numbers, 
and will adjust each unit's allocation amount under such paragraph 
upward or downward by one CSAPR SO2 Group 2 allowance (but 
not below zero) in the order in which the units are listed, and will 
repeat this adjustment process as necessary, until the total allocations 
from such new unit set-aside equal the total amount of such new unit 
set-aside.
    (b) Allocations from Indian country new unit set-asides. For each 
control period in 2015 and thereafter and for the CSAPR SO2 
Group 2 units in Indian country within the borders of each State, the

the Indian country new unit set-aside for such control period, divided 
by the sum under paragraph (b)(5) of this section, and rounded to the 
nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.711(b)(2)(i) and (ii), of the amount of CSAPR 
SO2 Group 2 allowances allocated under paragraphs (b)(2) 
through (7) and (12) of this section for such control period to each 
CSAPR SO2 Group 2 unit eligible for such allocation.
    (9) For a control period before 2021, if, after completion of the 
procedures under paragraphs (b)(5) through (8) of this section for such 
control period, any unallocated CSAPR SO2 Group 2 allowances 
remain in the Indian country new unit set-aside for the State for such 
control period, the Administrator will allocate such CSAPR 
SO2 Group 2 allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (b)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such

Sec. 97.724  Compliance with CSAPR SO2 Group 2 emissions limitation.

    (a) Availability for deduction for compliance. CSAPR SO2 
Group 2 allowances

[[Page 381]]

are available to be deducted for compliance with a source's CSAPR 
SO2 Group 2 emissions limitation for a control period in a 
given year only if the CSAPR SO2 Group 2 allowances:
    (1) Were allocated or auctioned for such control period or a control 
period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance 
transfer deadline for such control period.
    (b) Deductions for compliance. After the recordation, in accordance 
with Sec. 97.723, of CSAPR SO2 Group 2 allowance transfers 
submitted by the allowance transfer deadline for a control period in a 
given year, the Administrator will deduct from each source's compliance 
account CSAPR SO2 Group 2 allowances available under 
paragraph (a) of this section in order to determine whether the source 
meets the CSAPR SO2 Group 2 emissions limitation for such 
control period, as follows:
    (1) Until the amount of CSAPR SO2 Group 2 allowances 
deducted equals the number of tons of total SO2 emissions 
from all CSAPR SO2 Group 2 units at the source for such 
control period; or
    (2) If there are insufficient CSAPR SO2 Group 2 
allowances to complete the deductions in paragraph (b)(1) of this 
section, until no more CSAPR SO2 Group 2 allowances available 
under paragraph (a) of this section remain in the compliance account.
    (c) Selection of CSAPR SO2 Group 2 allowances for 
deduction--(1) Identification by serial number. The designated 
representative for a source may request that specific CSAPR 
SO2 Group 2 allowances, identified by serial number, in the 
source's compliance account be deducted for emissions or excess 
emissions for a control period in a given year in accordance with 
paragraph (b) or (d) of this section. In order to be complete, such 
request shall be submitted to the Administrator by the allowance 
transfer deadline for such control period and include, in a format 
prescribed by the Administrator, the identification of the CSAPR 
SO2 Group 2 source and the appropriate serial numbers.
    (2) First-in, first-out. The Administrator will deduct CSAPR 
SO2 Group 2 allowances under paragraph (b) or (d) of this 
section from the source's compliance account in accordance with a 
complete request under paragraph (c)(1) of this section or, in the 
absence of such request or in the case of identification of an 
insufficient amount of CSAPR SO2 Group 2 allowances in such 
request, on a first-in, first-out accounting basis in the following 
order:
    (i) Any CSAPR SO2 Group 2 allowances that were recorded 
in the compliance account pursuant to Sec. 97.721 and not transferred 
out of the compliance account, in the order of recordation; and then
    (ii) Any other CSAPR SO2 Group 2 allowances that were 
transferred to and recorded in the compliance account pursuant to this 
subpart, in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the CSAPR SO2 Group 2 source has excess 
emissions, the Administrator will deduct from the source's compliance 
account an amount of CSAPR SO2 Group 2 allowances, allocated 
or auctioned for a control period in a prior year or the control period 
in the year of the excess emissions or in the immediately following 
year, equal to two times the number of tons of the source's excess 
emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

SO2 Group 2 assurance provisions for a control period in a 
given year by the owners and operators of a group of one or more CSAPR 
SO2 Group 2 sources and units in a State (and Indian country 
within the borders of such State) only if the CSAPR SO2 Group 
2 allowances:
    (1) Were allocated or auctioned for a control period in a prior year 
or the

[[Page 382]]

control period in the given year or in the immediately following year; 
and
    (2) Are held in the assurance account, established by the 
Administrator for such owners and operators of such group of CSAPR 
SO2 Group 2 sources and units in such State (and Indian 
country within the borders of such State) under paragraph (b)(3) of this 
section, as of the deadline established in paragraph (b)(4) of this 
section.
    (b) Deductions for compliance. The Administrator will deduct CSAPR 
SO2 Group 2 allowances available under paragraph (a) of this

provisions for a State for a control period in a given year in 
accordance with the following procedures:
    (1) By June 1 of each year from 2018 through 2021 and August 1 of 
each year thereafter, the Administrator will:
    (i) Calculate, for each State (and Indian country within the borders 
of such State), the total SO2 emissions from all CSAPR 
SO2 Group 2 units at CSAPR SO2 Group 2 sources in 
the State (and Indian country within the borders of such State) during 
the control period in the year before the year of this calculation 
deadline and the amount, if any, by which such total SO2 
emissions exceed the State assurance level as described in Sec. 
97.706(c)(2)(iii); and
    (ii) For the set of any States (and Indian country within the 
borders of such States) for which the results of the calculations 
required in paragraph (b)(1)(i) of this section indicate that total 
SO2 emissions exceed the respective State assurance levels 
for such control period--
    (A) Calculate, for each such State (and Indian country within the 
borders of such State) and such control period and each common 
designated representative for such control period for a group of one or 
more CSAPR SO2 Group 2 sources and units in such State (and 
such Indian country), the common designated representative's share of 
the total SO2 emissions from all CSAPR SO2 Group 2 
units at CSAPR SO2 Group 2 sources in such State (and such 
Indian country), the common designated representative's assurance level, 
and the amount (if any) of CSAPR SO2 Group 2 allowances that 
the owners and operators of such group of sources and units must hold in 
accordance with the calculation formula in Sec. 97.706(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the SO2 emissions 
from each CSAPR SO2 Group 2 source in each such State (and 
Indian country within the borders of such State).
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.706(c)(2)(iii), Sec. Sec. 97.706(b) and 97.730 through 97.735, the 
definitions of ``common designated representative'', ``common designated 
representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.702, and the calculation formula in 
Sec. 97.706(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1 
immediately after the promulgation of such notice, the Administrator 
will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) For any State (and Indian country within the borders of such 
State) referenced in each notice of data availability required in 
paragraph (b)(2)(ii) of this section as having CSAPR SO2 
Group 2 units with total SO2 emissions exceeding the State 
assurance level for a control period in a given year, the Administrator 
will establish one assurance account for each set of owners and 
operators referenced, in the notice of

[[Page 383]]

data availability required under paragraph (b)(2)(ii) of this section, 
as all of the owners and operators of a group of CSAPR SO2 
Group 2 sources and units in the State (and Indian country within the 
borders of such State) having a common designated representative for 
such control period and as being required to hold CSAPR SO2 
Group 2 allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate CSAPR SO2 Group 
2 sources, CSAPR SO2 Group 2 units, and State (and Indian 
country within the borders of such State) under paragraph (b)(3) of this 
section a total amount of CSAPR SO2 Group 2 allowances, 
available for deduction under paragraph (a) of this section, equal to 
the amount such owners and operators are required to hold with regard to 
such sources, units and State (and Indian country within the borders of 
such State) as calculated by the Administrator and referenced in such 
notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.723, of CSAPR 
SO2 Group 2 allowance transfers submitted by midnight of such 
date, the Administrator will determine whether the owners and operators 
described in paragraph (b)(3) of this section hold, in the assurance 
account for the appropriate CSAPR SO2 Group 2 sources, CSAPR 
SO2 Group 2 units, and State (and Indian country within the 
borders of such State) established under paragraph (b)(3) of this 
section, the amount of CSAPR SO2 Group 2 allowances available 
under paragraph (a) of this section that the owners and operators are 
required to hold with regard to such sources, units, and State (and 
Indian country within the borders of such State) as calculated by the 
Administrator and referenced in the notice required in paragraph 
(b)(2)(ii) of this section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR SO2 Group 2 allowances that the owners and 
operators are required to hold in accordance with Sec. 97.706(c)(2)(i) 
for such control period shall continue to be such amounts as calculated 
by the Administrator and referenced in such notice required in paragraph 
(b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator will use the 
data as so revised to recalculate the amounts of CSAPR SO2 
Group 2 allowances that owners and operators are required to hold in 
accordance with the calculation formula in Sec. 97.706(c)(2)(i) for 
such control period with regard to the CSAPR SO2 Group 2 
sources, CSAPR SO2 Group 2 units, and State (and Indian 
country within the borders of such State) involved, provided that such 
litigation under part 78 of this chapter, or the proceeding under part 
78 of this chapter that resulted in the decision appealed in such 
litigation under section 307 of the Clean Air Act, was initiated no 
later than 30 days after promulgation of such notice required in 
paragraph (b)(2)(ii) of this section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the

[[Page 384]]

amount of CSAPR SO2 Group 2 allowances that the owners and 
operators are required to hold for such control period with regard to 
the CSAPR SO2 Group 2 sources, CSAPR SO2 Group 2 
units, and State (and Indian country within the borders of such State) 
involved--
    (A) Where the amount of CSAPR SO2 Group 2 allowances that 
the owners and operators are required to hold increases as a result of 
the use of all such revised data, the Administrator will establish a 
new, reasonable deadline on which the owners and operators shall hold 
the additional amount of CSAPR SO2 Group 2 allowances in the 
assurance account established by the Administrator for the appropriate 
CSAPR SO2 Group 2 sources, CSAPR SO2 Group 2 
units, and State (and Indian country within the borders of such State) 
under paragraph (b)(3) of this section. The owners' and operators' 
failure to hold such additional amount, as required, before the new 
deadline shall not be a violation of the Clean Air Act. The owners' and 
operators' failure to hold such additional amount, as required, as of 
the new deadline shall be a violation of the Clean Air Act. Each CSAPR 
SO2 Group 2 allowance that the owners and operators fail to 
hold as required as of the new deadline, and each day in such control 
period, shall be a separate violation of the Clean Air Act.
    (B) For the owners and operators for which the amount of CSAPR 
SO2 Group 2 allowances required to be held decreases as a 
result of the use of all such revised data, the Administrator will 
record, in all accounts from which CSAPR SO2 Group 2 
allowances were transferred by such owners and operators for such 
control period to the assurance account established by the Administrator 
for the appropriate CSAPR SO2 Group 2 sources, CSAPR 
SO2 Group 2 units, and State (and Indian country within the 
borders of such State) under paragraph (b)(3) of this section, a total 
amount of the CSAPR SO2 Group 2 allowances held in such 
assurance account equal to the amount of the decrease. If CSAPR 
SO2 Group 2 allowances were transferred to such assurance 
account from more than one account, the amount of CSAPR SO2 
Group 2 allowances recorded in each such transferor account will be in 
proportion to the percentage of the total amount of CSAPR SO2 
Group 2 allowances transferred to such assurance account for such 
control period from such transferor account.
    (C) Each CSAPR SO2 Group 2 allowance held under paragraph 
(b)(6)(iii)(A) of this section as a result of recalculation of 
requirements under the CSAPR SO2 Group 2 assurance provisions 
for such control period must be a CSAPR SO2 Group 2 allowance 
allocated for a control period in a year before or the year immediately 
following, or in the same year as, the year of such control period.

submit to the Administrator a certification application for each 
monitoring system. A complete certification application shall include 
the information specified in Sec. 75.63 of this chapter.
    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CSAPR SO2 Group 2 Trading 
Program for a period not to exceed 120 days after receipt by the 
Administrator of the complete certification application for the 
monitoring system under paragraph (d)(3)(ii) of this section. Data 
measured and recorded by the provisionally certified monitoring system, 
in accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the Administrator does not 
invalidate the provisional certification by issuing a notice of 
disapproval within 120 days of the date of receipt of the complete 
certification application by the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph

issue such a notice within such 120-day period, each monitoring system 
that meets the applicable performance requirements of part 75 of this 
chapter and is included in the certification application will be deemed 
certified for use under the CSAPR SO2 Group 2 Trading 
Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the designated 
representative must submit the additional information required to 
complete the certification application. If the designated representative 
does not comply with the notice of incompleteness by the specified date, 
then the Administrator may issue a notice of disapproval under paragraph 
(d)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter).
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.732(b).
    (v) Procedures for loss of certification. If the Administrator 
issues a notice of disapproval of a certification application under 
paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (d)(3)(iv)(D) of this section, 
then:

application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.731 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.731 for 
each disapproved monitoring system.

Sec. 97.811  Timing requirements for CSAPR NOX Ozone Season Group 2 allowance allocations.

    (a) Existing units. (1) CSAPR NOX Ozone Season Group 2 
allowances are allocated, for the control periods in 2017 and each year 
thereafter, as provided in a notice of data availability issued by the 
Administrator. Providing an allocation to a unit in such notice does not 
constitute a determination that the unit is a CSAPR NOX Ozone 
Season Group 2 unit, and not providing an allocation to a unit in such 
notice does not constitute a determination that the unit is not a CSAPR 
NOX Ozone Season Group 2 unit.
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting after 2016, 
during the control period in two consecutive years, such unit will not 
be allocated the CSAPR NOX Ozone Season Group 2 allowances 
provided in such notice for the unit for the control periods in the 
fifth year after the first such year and in each year after that fifth 
year. All CSAPR NOX Ozone Season Group 2 allowances that 
would otherwise have been allocated to such unit will be allocated to 
the new unit set-aside for the State where such unit is located and for 
the respective years involved. If such unit resumes operation, the 
Administrator will allocate CSAPR NOX Ozone Season Group 2 
allowances to the unit in accordance with paragraph (b) of this section.
    (b) New units--(1) New unit set-asides. (i)(A) By June 1 of each 
year from 2017 through 2020, the Administrator will calculate the CSAPR 
NOX Ozone Season Group 2 allowance allocation to each CSAPR 
NOX Ozone Season Group 2 unit in a State, in accordance with 
Sec. 97.812(a)(2) through (7) and (12) and Sec. Sec. 97.806(b)(2) and 
97.830 through 97.835, for the control period in the year of the 
applicable calculation deadline under this paragraph and will promulgate 
a notice of data availability of the results of the calculations.
    (B) By March 1, 2022 and March 1 of each year thereafter, the 
Administrator will calculate the CSAPR NOX Ozone Season Group 
2 allowance allocation to each CSAPR NOX Ozone Season Group 2 
unit in a State, in accordance with Sec. 97.812(a)(2) through (7), 
(10), and (12) and Sec. Sec. 97.806(b)(2) and 97.830 through 97.835, 
for the control period in the year before the year of the applicable 
calculation deadline under this paragraph and will promulgate a notice 
of data availability of the results of the calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(1)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(1)(i) of this 
section and shall be limited to addressing whether the calculations 
(including the identification of the CSAPR NOX Ozone Season 
Group 2 units) are in accordance with the provisions referenced in 
paragraph (b)(1)(i)(A) or (B) of this section, as applicable.
    (B) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance

[[Page 410]]

with the provisions referenced in paragraph (b)(1)(i)(A) or (B) of this 
section, as applicable. By August 1 immediately after the promulgation 
of each notice of data availability required in paragraph (b)(1)(i)(A) 
of this section, or by May 1 immediately after the promulgation of each 
notice of data availability required in paragraph (b)(1)(i)(B) of this 
section, the Administrator will promulgate a notice of data availability 
of the results of the calculations incorporating any adjustments that 
the Administrator determines to be necessary and the reasons for 
accepting or rejecting any objections submitted in accordance with 
paragraph (b)(1)(ii)(A) of this section.
    (iii) If the new unit set-aside for a control period before 2021 
contains any CSAPR NOX Ozone Season Group 2 allowances that 
have not been allocated in the applicable notice of data availability 
required in paragraph (b)(1)(ii) of this section, the Administrator will 
promulgate, by December 15 immediately after such notice, a notice of 
data availability that identifies any CSAPR NOX Ozone Season 
Group 2 units that commenced commercial operation during the period 
starting January 1 of the year before the year of such control period 
and ending November 30 of the year of such control period.
    (iv) For each notice of data availability required in paragraph

notice of data availability required in paragraph (b)(1)(iii) of this 
section and shall be limited to addressing whether the identification of 
CSAPR NOX Ozone Season Group 2 units in such notice is in 
accordance with paragraph (b)(1)(iii) of this section.
    (B) The Administrator will adjust the identification of CSAPR 
NOX Ozone Season Group 2 units in each notice of data 
availability required in paragraph (b)(1)(iii) of this section to the 
extent necessary to ensure that it is in accordance with paragraph 
(b)(1)(iii) of this section and will calculate the CSAPR NOX 
Ozone Season Group 2 allowance allocation to each CSAPR NOX 
Ozone Season Group 2 unit in accordance with Sec. 97.812(a)(9), (10), 
and (12) and Sec. Sec. 97.806(b)(2) and 97.830 through 97.835. By 
February 15 immediately after the promulgation of each notice of data 
availability required in paragraph (b)(1)(iii) of this section, the 
Administrator will promulgate a notice of data availability of any 
adjustments of the identification of CSAPR NOX Ozone Season 
Group 2 units that the Administrator determines to be necessary, the 
reasons for accepting or rejecting any objections submitted in 
accordance with paragraph (b)(1)(iv)(A) of this section, and the results 
of such calculations.
    (v) To the extent any CSAPR NOX Ozone Season Group 2 
allowances are added to the new unit set-aside after promulgation of 
each notice of data availability required in paragraph (b)(1)(iv) of 
this section for a control period before 2021, or in paragraph 
(b)(1)(ii) of this section for a control period in 2021 or thereafter, 
the Administrator will promulgate additional notices of data 
availability, as deemed appropriate, of the allocation of such CSAPR 
NOX Ozone Season Group 2 allowances in accordance with Sec.

of such calculations.
    (v) To the extent any CSAPR NOX Ozone Season Group 2 
allowances are added to the Indian country new unit set-aside after 
promulgation of each notice of data availability required in paragraph 
(b)(2)(iv) of this section for a control period before 2021, or in

    (c) Units incorrectly allocated CSAPR NOX Ozone Season 
Group 2 allowances. (1) For each control period in 2017 and thereafter, 
if the Administrator determines that CSAPR NOX Ozone Season 
Group 2 allowances were allocated under paragraph (a) of this section, 
or under a provision of a SIP revision approved under Sec. 52.38(b)(7), 
(8), or (9) of this chapter, where such control period and the recipient 
are covered by the provisions of paragraph (c)(1)(i) of this section or 
were allocated under Sec. 97.812(a)(2) through (7), (9), and (12) and 
(b)(2) through (7), (9), and (12), or under a provision of a SIP 
revision approved under Sec. 52.38(b)(8) or (9) of this chapter, where 
such control period and the recipient are covered by the provisions of 
paragraph (c)(1)(ii) of this section, then the Administrator will notify 
the designated representative of the recipient and will act in 
accordance with the procedures set forth in paragraphs (c)(2) through 
(5) of this section:
    (i)(A) The recipient is not actually a CSAPR NOX Ozone 
Season Group 2 unit under Sec. 97.804 as of May 1, 2017 and is 
allocated CSAPR NOX Ozone Season Group 2 allowances for such 
control period or, in the case of an allocation under a provision of a 
SIP revision approved under Sec. 52.38(b)(7), (8), or (9) of this 
chapter, the recipient is not actually a CSAPR NOX Ozone 
Season Group 2 unit as of May 1, 2017 and is allocated CSAPR 
NOX Ozone Season Group 2 allowances for such control period 
that the SIP revision provides should be allocated only to recipients 
that are CSAPR NOX Ozone Season Group 2 units as of May 1,

NOX Ozone Season Group 2 unit as of May 1 of such control 
period and is allocated CSAPR NOX Ozone Season Group 2 
allowances for such control period that the SIP revision provides should 
be allocated only to recipients that are CSAPR NOX Ozone 
Season Group 2 units as of May 1 of such control period.
    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such CSAPR NOX Ozone Season 
Group 2 allowances under Sec. 97.821.
    (3) If the Administrator already recorded such CSAPR NOX 
Ozone Season Group 2 allowances under Sec. 97.821 and if the 
Administrator makes the determination under paragraph (c)(1) of this 
section before making deductions for the source that includes such 
recipient under Sec. 97.824(b) for such control period, then the 
Administrator will deduct from the account in which such CSAPR 
NOX Ozone Season Group 2 allowances were recorded an amount 
of CSAPR NOX Ozone Season Group 2 allowances allocated for 
the same or a prior control period equal to the amount of such already 
recorded CSAPR NOX Ozone Season Group 2 allowances. The 
authorized account representative shall ensure that there are sufficient 
CSAPR NOX Ozone Season Group 2 allowances in such account for 
completion of the deduction.
    (4) If the Administrator already recorded such CSAPR NOX 
Ozone Season Group 2 allowances under Sec. 97.821 and if the 
Administrator makes the determination under paragraph (c)(1) of this

    (5)(i) With regard to the CSAPR NOX Ozone Season Group 2 
allowances that are not recorded, or that are deducted as an incorrect 
allocation, in accordance with paragraphs (c)(2) and (3) of

[[Page 413]]

this section for a recipient under paragraph (c)(1)(i) of this section, 
the Administrator will:
    (A) Transfer such CSAPR NOX Ozone Season Group 2

subsequent control period) for the State from whose NOX Ozone 
Season Group 2 trading budget the CSAPR NOX Ozone Season 
Group 2 allowances were allocated; or
    (B) If the State has a SIP revision approved under Sec. 52.38(b)(8)

accordance with such SIP revision.
    (ii) With regard to the CSAPR NOX Ozone Season Group 2

    (A) Transfer such CSAPR NOX Ozone Season Group 2 
allowances to the new unit set-aside for such control period (or a 
subsequent control period); or
    (B) If the State has a SIP revision approved under Sec. 52.38(b)(8) 
or (9) of this chapter covering such control period, include such CSAPR 
NOX Ozone Season Group 2 allowances in the portion of the 
State NOX Ozone Season Group 2 trading budget that may be 
allocated for such control period (or a subsequent control period) in 
accordance with such SIP revision.
    (iii) With regard to the CSAPR NOX Ozone Season Group 2

deducted as an incorrect allocation, in accordance with paragraphs 
(c)(2) and (3) of this section for a recipient under paragraph 
(c)(1)(ii) of this section, the Administrator will transfer such CSAPR 
NOX Ozone Season Group 2 allowances to the Indian country new 
unit set-aside for such control period (or a subsequent control period).
    (d) Recall of CSAPR NOX Ozone Season Group 2 allowances 
allocated for control periods after 2020. (1) Notwithstanding any other 
provision of this subpart, part 52 of this chapter, or any SIP revision 
approved under Sec. 52.38(b) of this chapter, the provisions of this 
paragraph and paragraphs (d)(2) through (7) of this section shall apply 
with regard to each CSAPR NOX Ozone Season Group 2 allowance 
that was allocated for a control period after 2020 to any unit 
(including a permanently retired unit qualifying for an exemption under 
Sec. 97.805) in a State listed in Sec. 52.38(b)(2)(iv) of this chapter 
(or Indian country within the borders of such a State) and that was 
initially recorded in the compliance account for the source that 
includes the unit, whether such CSAPR NOX Ozone Season Group 
2 allowance was allocated pursuant to this subpart or pursuant to a SIP

    (2)(i) For each CSAPR NOX Ozone Season Group 2 allowance 
described in paragraph (d)(1) of this section that was allocated for a 
given control period and initially recorded in a given source's

allowance that was allocated for the same or an earlier control period 
and initially recorded in the same or any other Allowance Management 
System account must be surrendered in accordance with the procedures in 
paragraphs (d)(3) and (4) of this section.
    (ii)(A) The surrender requirement under paragraph (d)(2)(i) of this 
section corresponding to each CSAPR NOX Ozone Season Group 2 
allowance described in paragraph (d)(1) of this section initially 
recorded in a given source's compliance account shall apply to such 
source's current owners and operators, except as provided in paragraph 
(d)(2)(ii)(B) of this section.
    (B) If the owners and operators of a given source as of a given date 
assumed ownership and operational control of the source through a 
transaction that

[[Page 414]]

did not also provide rights to direct the use or transfer of a given 
CSAPR NOX Ozone Season Group 2 allowance described in 
paragraph (d)(1) of this section with regard to such source (whether 
recordation of such CSAPR NOX Ozone Season Group 2 allowance 
in the source's compliance account occurred before such transaction or 
was anticipated to occur after such transaction), then the surrender

    (ii) As soon as practicable on or after July 14, 2021, the 
Administrator will deduct from the compliance account for each source 
described in paragraph (d)(1) of this section CSAPR NOX Ozone 
Season Group 2 allowances eligible to satisfy the surrender requirements

    (iii) As soon as practicable after completion of the deductions 
under paragraph (d)(3)(ii) of this section, the Administrator will 
identify for each source described in paragraph (d)(1) of this section 
the amounts, if any, of CSAPR NOX Ozone Season Group 2 
allowances allocated for each control period after 2020 and recorded in 
the source's compliance account for which the corresponding surrender 
requirements under paragraph (d)(2)(i) of this section have not been 
satisfied and will send a notification concerning such identified 
amounts to the designated representative for the source.
    (iv) With regard to each source for which unsatisfied surrender

sufficient CSAPR NOX Ozone Season Group 2 allowances eligible 
to satisfy such portion of the unsatisfied surrender requirements under 
paragraph (d)(2)(i) of this section either in the source's compliance 
account or in another Allowance Management System account identified to 
the Administrator on or before such date in a submission by the 
authorized account representative for such account.
    (C) As soon as practicable on or after September 15, 2021, the 
Administrator will deduct from the Allowance Management System account 
identified in accordance with paragraph (d)(3)(iv)(A) or (B) of this 
section CSAPR NOX Ozone Season Group 2 allowances eligible to 
satisfy the surrender requirements for the source under paragraph 
(d)(2)(i) of this section until all such surrender requirements for the 
source are satisfied or until no more CSAPR NOX Ozone Season 
Group 2 allowances

[[Page 415]]

eligible to satisfy such surrender requirements remain in such account.
    (v) When making deductions under paragraph (d)(3)(ii) or (iv) of 
this section to address the surrender requirements under paragraph 
(d)(2)(i) of this section for a given source:
    (A) The Administrator will make deductions to address any surrender

    (B) When making deductions to address the surrender requirements 
with regard to a given control period, the Administrator will first

Ozone Season Group 2 allowances allocated for each successively earlier 
control period in sequence.
    (C) When deducting CSAPR NOX Ozone Season Group 2 
allowances allocated for a given control period from a given Allowance 
Management System account, the Administrator will first deduct CSAPR 
NOX Ozone Season Group 2 allowances initially recorded in the 
account under Sec. 97.821 (if the account is a compliance account) in 
the order of recordation and will then deduct CSAPR NOX Ozone 
Season Group 2 allowances recorded in the account under Sec. 97.526(d) 
or Sec. 97.823 in the order of recordation.
    (4)(i) To the extent the surrender requirements under paragraph 
(d)(2)(i) of this section corresponding to any CSAPR NOX 
Ozone Season Group 2 allowances allocated for a control period after 
2020 and initially recorded in a given source's compliance account have 
not been fully satisfied through the deductions under paragraph (d)(3)

the Administrator will deduct such initially recorded CSAPR 
NOX Ozone Season Group 2 allowances from any Allowance 
Management System accounts in which such CSAPR NOX Ozone 
Season Group 2 allowances are held, making such deductions in any order 
determined by the Administrator, until all such surrender requirements 
for such source have been satisfied or until all such CSAPR 
NOX Ozone Season Group 2 allowances have been deducted, 
except as provided in paragraph (d)(4)(ii) of this section.
    (ii) If no person with an ownership interest in a given CSAPR 
NOX Ozone Season Group 2 allowance as of January 31, 2021 was 
an owner or operator of the source in whose compliance account such 
CSAPR NOX Ozone Season Group 2 allowance was initially 
recorded, was a direct or indirect parent or subsidiary of an owner or 
operator of such source, or was directly or indirectly under common 
ownership with an owner or operator of such source, the Administrator 
will not deduct such CSAPR NOX Ozone Season Group 2 allowance 
under paragraph (d)(4)(i) of this section. For purposes of this 
paragraph, each owner or operator of a source shall be deemed to be a 
person with an ownership interest in any CSAPR NOX Ozone 
Season Group 2 allowance held in that source's compliance account. The 
limitation established by this paragraph on the deductibility of certain 
CSAPR NOX Ozone Season Group 2 allowances under paragraph 
(d)(4)(i) of this section shall not be construed as a waiver of the 
surrender requirements under paragraph (d)(2)(i) of this section 
corresponding to such CSAPR NOX Ozone Season Group 2 
allowances.
    (iii) Not less than 45 days before the planned date for any 
deductions under paragraph (d)(4)(i) of this section, the Administrator 
will send a notification to the authorized account representative for 
the Allowance Management System account from which such deductions will 
be made identifying the CSAPR NOX Ozone Season Group 2

(d)(2)(i) of this section corresponding to any CSAPR NOX 
Ozone Season Group 2 allowances allocated for a control period after 
2020 and initially recorded in a given source's compliance account

[[Page 416]]

have not been fully satisfied through the deductions under paragraphs 
(d)(3) and (4) of this section:
    (i) The persons identified in accordance with paragraph (d)(2)(ii) 
of this section with regard to such source and each such CSAPR 
NOX Ozone Season Group 2 allowance shall pay any fine, 
penalty, or assessment or comply with any other remedy imposed under the 
Clean Air Act; and
    (ii) Each such CSAPR NOX Ozone Season Group 2 allowance, 
and each day in such control period, shall constitute a separate 
violation of this subpart and the Clean Air Act.
    (6) The Administrator will record in the appropriate Allowance 
Management System accounts all deductions of CSAPR NOX Ozone 
Season Group 2 allowances under paragraphs (d)(3) and (4) of this 
section.

amounts of CSAPR NOX Ozone Season Group 2 allowances 
determined for all such

[[Page 420]]

CSAPR NOX Ozone Season Group 2 units under paragraph 
(a)(4)(i) of this section in the State for such control period.
    (6) If the amount of CSAPR NOX Ozone Season Group 2 
allowances in the new unit set-aside for the State for such control 
period is greater than or equal to the sum under paragraph (a)(5) of 
this section, then the Administrator will allocate the amount of CSAPR 
NOX Ozone Season Group 2 allowances determined for each such 
CSAPR NOX Ozone Season Group 2 unit under paragraph (a)(4)(i) 
of this section.
    (7) If the amount of CSAPR NOX Ozone Season Group 2 
allowances in the new unit set-aside for the State for such control 
period is less than the sum under paragraph (a)(5) of this section, then 
the Administrator will allocate to each such CSAPR NOX Ozone 
Season Group 2 unit the amount of the CSAPR NOX Ozone Season 
Group 2 allowances determined under paragraph (a)(4)(i) of this section 
for the unit, multiplied by the amount of CSAPR NOX Ozone 
Season Group 2 allowances in the new unit set-aside for such control 
period, divided by the sum under paragraph (a)(5) of this section, and 
rounded to the nearest allowance.
    (8) For a control period before 2021, the Administrator will notify 
the public, through the promulgation of the notices of data availability 
described in Sec. 97.811(b)(1)(i) and (ii), of the amount of CSAPR 
NOX Ozone Season Group 2 allowances allocated under

period to each CSAPR NOX Ozone Season Group 2 unit eligible 
for such allocation.
    (9) For a control period before 2021, if, after completion of the 
procedures under paragraphs (a)(5) through (8) of this section for such 
control period, any unallocated CSAPR NOX Ozone Season Group 
2 allowances remain in the new unit set-aside for the State for such 
control period, the Administrator will allocate such CSAPR 
NOX Ozone Season Group 2 allowances as follows--
    (i) The Administrator will determine, for each unit described in 
paragraph (a)(1) of this section that commenced commercial operation 
during the period starting January 1 of the year before the year of such 
control period and ending November 30 of the year of such control 
period, the positive difference (if any) between the unit's emissions 
during such control period and the amount of CSAPR NOX Ozone 
Season Group 2 allowances referenced in the notice of data availability 
required under Sec. 97.811(b)(1)(ii) for the unit for such control 
period;
    (ii) The Administrator will determine the sum of the positive 
differences determined under paragraph (a)(9)(i) of this section;
    (iii) If the amount of unallocated CSAPR NOX Ozone Season 
Group 2 allowances remaining in the new unit set-aside for the State for 
such control period is greater than or equal to the sum determined under

amount of unallocated CSAPR NOX Ozone Season Group 2 
allowances remaining in the new unit set-aside for such control period, 
divided by the sum under paragraph (a)(9)(ii) of this section, and 
rounded to the nearest allowance.
    (10) If, after completion of the procedures under paragraphs (a)(9) 
and (12) of this section for a control period before 2021, or under 
paragraphs (a)(2) through (7) and (12) of this section for a control 
period in 2021 or thereafter, any unallocated CSAPR NOX Ozone 
Season Group 2 allowances remain in the new unit set-aside for the State 
for such control period, the Administrator will allocate to each CSAPR 
NOX Ozone Season Group 2 unit that is in the State, is 
allocated an amount of

[[Page 421]]

CSAPR NOX Ozone Season Group 2 allowances in the notice of 
data availability issued under Sec. 97.811(a)(1), and continues to be 
allocated CSAPR NOX Ozone Season Group 2 allowances for such 
control period in accordance with Sec. 97.811(a)(2), an amount of CSAPR 
NOX Ozone Season Group 2 allowances equal to the following: 
The total amount of such remaining unallocated CSAPR NOX 
Ozone Season Group 2 allowances in such new unit set-aside, multiplied 
by the unit's allocation under Sec. 97.811(a) for such control period, 
divided by the remainder of the amount of tons in the applicable State 
NOX Ozone Season Group 2 trading budget minus the sum of the 
amounts of tons in such new unit set-aside and the Indian country new 
unit set-aside for the State for such control period, and rounded to the 
nearest allowance.
    (11)(i) For a control period before 2021, the Administrator will 
notify the public, through the promulgation of the notices of data 
availability described in Sec. 97.811(b)(1)(iii), (iv), and (v), of the 
amount of CSAPR NOX Ozone Season Group 2 allowances allocated 
under paragraphs (a)(9), (10), and (12) of this section for such control 
period to each CSAPR NOX Ozone Season Group 2 unit eligible 
for such allocation.

amount of CSAPR NOX Ozone Season Group 2 allowances allocated 
under paragraphs (a)(2) through (7), (10), and (12) of this section for 
such control period to each CSAPR NOX Ozone Season Group 2 
unit eligible for such allocation.
    (12) Notwithstanding the requirements of paragraphs (a)(2) through 
(11) of this section, if the calculations of allocations from a new unit 
set-aside for a control period before 2021 under paragraph (a)(7) of 
this section, paragraphs (a)(6) and (a)(9)(iv) of this section, or 
paragraphs (a)(6), (a)(9)(iii), and (a)(10) of this section, or for a 
control period in 2021 or thereafter under paragraph (a)(7) of this 
section or paragraphs (a)(6) and (10) of this section, would otherwise 
result in total allocations from such new unit set-aside unequal to the 
total amount of such new unit set-aside, then the Administrator will 
adjust the results of such calculations as follows. The Administrator 
will list the CSAPR NOX Ozone Season Group 2 units in 
descending order based on such units' allocation amounts under paragraph 
(a)(7), (a)(9)(iv), or (a)(10) of this section, as applicable, and, in 
cases of equal allocation amounts, in alphabetical order of the relevant 
sources' names and numerical order of the relevant units' identification 
numbers, and will adjust each unit's allocation amount under such 
paragraph upward or downward by one CSAPR NOX Ozone Season 
Group 2 allowance (but not below zero) in the order in which the units 
are listed, and will repeat this adjustment process as necessary, until 
the total allocations from such new unit set-aside equal the total 
amount of such new unit set-aside.
    (b) Allocations from Indian country new unit set-asides. For each 
control period in 2017 and thereafter and for the CSAPR NOX 
Ozone Season Group 2 units in Indian country within the borders of each

paragraph (b)(7) of this section or paragraphs (b)(6) and (b)(9)(iv) of 
this section, or for a control period in 2021 or thereafter under 
paragraph (b)(7) of this section, would otherwise result in total 
allocations from such Indian country new unit set-aside unequal to the 
total amount of such Indian country new unit set-aside, then the 
Administrator will adjust the results of such calculations as follows. 
The Administrator will list the CSAPR NOX Ozone Season Group 
2 units in descending order based on such units' allocation amounts 
under paragraph (b)(7) or (b)(9)(iv) of this section, as applicable, 
and, in cases of equal allocation amounts, in alphabetical order of the 
relevant sources' names and numerical order of the relevant units' 
identification numbers, and will adjust each unit's allocation amount 
under such paragraph upward or downward by

[[Page 424]]

one CSAPR NOX Ozone Season Group 2 allowance (but not below 
zero) in the order in which the units are listed, and will repeat this 
adjustment process as necessary, until the total allocations from such 
Indian country new unit set-aside equal the total amount of such Indian 
country new unit set-aside.

Sec. 97.824  Compliance with CSAPR NOX Ozone Season Group 2 emissions limitation.

    (a) Availability for deduction for compliance. CSAPR NOX 
Ozone Season Group 2 allowances are available to be deducted for 
compliance with a source's CSAPR NOX Ozone Season Group 2 
emissions limitation for a control period in a given year only if the 
CSAPR NOX Ozone Season Group 2 allowances:
    (1) Were allocated or auctioned for such control period or a control 
period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance

with Sec. 97.823, of CSAPR NOX Ozone Season Group 2 
allowance transfers submitted by the allowance transfer deadline for a 
control period in a given year, the Administrator will deduct from each 
source's compliance account CSAPR NOX Ozone Season Group 2 
allowances available under paragraph (a) of this section in order to 
determine whether the source meets the CSAPR NOX Ozone Season 
Group 2 emissions limitation for such control period, as follows:
    (1) Until the amount of CSAPR NOX Ozone Season Group 2 
allowances deducted equals the number of tons of total NOX 
emissions from all CSAPR NOX Ozone Season Group 2 units at 
the source for such control period; or
    (2) If there are insufficient CSAPR NOX Ozone Season 
Group 2 allowances to complete the deductions in paragraph (b)(1) of 
this section, until no more CSAPR NOX Ozone Season Group 2 
allowances available under paragraph (a) of this section remain in the 
compliance account.
    (c) Selection of CSAPR NOX Ozone Season Group 2 
allowances for deduction--(1) Identification by serial number. The 
designated representative for a source may request that specific CSAPR 
NOX Ozone Season Group 2 allowances, identified by serial 
number, in the source's compliance account be deducted for emissions or 
excess emissions for a control period in a given year in accordance with 
paragraph (b) or (d) of this section. In order to be complete, such 
request shall be submitted to the Administrator by the allowance 
transfer deadline for such control period and include, in a format 
prescribed by the Administrator, the identification of the CSAPR 
NOX Ozone Season Group 2 source and the appropriate serial 
numbers.
    (2) First-in, first-out. The Administrator will deduct CSAPR 
NOX Ozone Season Group 2 allowances under paragraph (b) or 
(d) of this section from the source's compliance account in accordance 
with a complete request under paragraph (c)(1) of this section or, in 
the absence of such request or in the case of identification of an 
insufficient amount of CSAPR NOX Ozone Season Group 2 
allowances in such request, on a first-in, first-out accounting basis in 
the following order:
    (i) Any CSAPR NOX Ozone Season Group 2 allowances that 
were recorded in the compliance account pursuant to Sec. 97.821 and not 
transferred out of the compliance account, in the order of recordation;

    (ii) Any other CSAPR NOX Ozone Season Group 2 allowances 
that were transferred to and recorded in the compliance account pursuant 
to this subpart or that were recorded in the compliance account pursuant 
to Sec. 97.526(d), in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the CSAPR NOX Ozone Season Group 2 source has 
excess emissions, the Administrator will deduct from the source's 
compliance account an amount of CSAPR NOX Ozone Season Group 
2 allowances, allocated or auctioned for a control period in a prior 
year or the control period in the year of the excess emissions or in the 
immediately following year, equal to two times the number of tons of the 
source's excess emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

Ozone Season Group 2 sources, base CSAPR NOX Ozone Season 
Group 2 units, and State (and Indian country within the borders of such 
State) under paragraph (b)(3) of this section a total amount of CSAPR 
NOX Ozone Season Group 2 allowances, available for deduction 
under paragraph (a) of this section, equal to the amount such owners and 
operators are required to hold with regard to such sources, units and 
State (and Indian country within the borders of such State) as 
calculated by the Administrator and referenced in such notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.823, of CSAPR 
NOX Ozone Season Group 2 allowance transfers submitted by 
midnight of such date, the Administrator will determine whether the 
owners and operators described in paragraph (b)(3) of this section hold, 
in the assurance account for the appropriate base CSAPR NOX 
Ozone Season Group 2 sources, base CSAPR NOX Ozone Season 
Group 2 units, and State (and Indian country within the borders of such 
State) established under paragraph (b)(3) of this section, the amount of 
CSAPR NOX Ozone Season Group 2 allowances available under 
paragraph (a) of this section that the owners and operators are required 
to hold with regard to such sources, units, and State (and Indian 
country within the borders of such State) as calculated by the 
Administrator and referenced in the notice required in paragraph 
(b)(2)(ii) of this section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR NOX Ozone Season Group 2 allowances that the 
owners and operators are required to hold in accordance with Sec. 
97.806(c)(2)(i) for such control period shall continue to be such 
amounts as calculated by the Administrator and referenced in such notice 
required in paragraph (b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean

[[Page 439]]

Air Act of a decision rendered under part 78 of this chapter on appeal 
of such notice, then the Administrator will use the data as so revised 
to recalculate the amounts of CSAPR NOX Ozone Season Group 2 
allowances that owners and operators are required to hold in accordance 
with the calculation formula in Sec. 97.806(c)(2)(i) for such control 
period with regard to the base CSAPR NOX Ozone Season Group 2 
sources, base CSAPR NOX Ozone Season Group 2 units, and State 
(and Indian country within the borders of such State) involved, provided 
that such litigation under part 78 of this chapter, or the proceeding 
under part 78 of this chapter that resulted in the decision appealed in 
such litigation under section 307 of the Clean Air Act, was initiated no 
later than 30 days after promulgation of such notice required in 
paragraph (b)(2)(ii) of this section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of CSAPR 
NOX Ozone Season Group 2 allowances that the owners and 
operators are required to hold for such control period with regard to 
the base CSAPR NOX Ozone Season Group 2 sources, base CSAPR 
NOX Ozone Season Group 2 units, and State (and Indian country 
within the borders of such State) involved--
    (A) Where the amount of CSAPR NOX Ozone Season Group 2 
allowances that the owners and operators are required to hold increases 
as a result of the use of all such revised data, the Administrator will 
establish a new, reasonable deadline on which the owners and operators 
shall hold the additional amount of CSAPR NOX Ozone Season 
Group 2 allowances in the assurance account established by the 
Administrator for the appropriate base CSAPR NOX Ozone Season 
Group 2 sources, base CSAPR NOX Ozone Season Group 2 units, 
and State (and Indian country within the borders of such State) under 
paragraph (b)(3) of this section. The owners' and operators' failure to 
hold such additional amount, as required, before the new deadline shall 
not be a violation of the Clean Air Act. The owners' and operators' 
failure to hold such additional amount, as required, as of the new 
deadline shall be a violation of the Clean Air Act. Each CSAPR 
NOX Ozone Season Group 2 allowance that the owners and 
operators fail to hold as required as of the new deadline, and each day 
in such control period, shall be a separate violation of the Clean Air 
Act.
    (B) For the owners and operators for which the amount of CSAPR 
NOX Ozone Season Group 2 allowances required to be held 
decreases as a result of the use of all such revised data, the 
Administrator will record, in all accounts from which CSAPR 
NOX Ozone Season Group 2 allowances were transferred by such 
owners and operators for such control period to the assurance account 
established by the Administrator for the appropriate base CSAPR 
NOX Ozone Season Group 2 sources, base CSAPR NOX 
Ozone Season Group 2 units, and State (and Indian country within the 
borders of such State) under paragraph (b)(3) of this section, a total 
amount of the CSAPR NOX Ozone Season Group 2 allowances held 
in such assurance account equal to the amount of the decrease. If CSAPR 
NOX Ozone Season Group 2 allowances were transferred to such 
assurance account from more than one account, the amount of CSAPR 
NOX Ozone Season Group 2 allowances recorded in each such 
transferor account will be in proportion to the percentage of the total 
amount of CSAPR NOX Ozone Season Group 2 allowances 
transferred to such assurance account for such control period from such 
transferor account.
    (C) Each CSAPR NOX Ozone Season Group 2 allowance held 
under paragraph (b)(6)(iii)(A) of this section as a result of 
recalculation of requirements under the CSAPR NOX Ozone 
Season Group 2 assurance provisions for such control period must be a 
CSAPR NOX Ozone Season Group 2 allowance allocated for a 
control period in a year before or the year immediately following, or in 
the same year as, the year of such control period.

Sec. 97.826  Banking and conversion.

    (a) A CSAPR NOX Ozone Season Group 2 allowance may be 
banked for future use or transfer in a compliance account or a general 
account in accordance with paragraph (b) of this section.
    (b) Any CSAPR NOX Ozone Season Group 2 allowance that is 
held in a compliance account or a general account will remain in such 
account unless and until the CSAPR NOX Ozone Season Group 2 
allowance is deducted or transferred under Sec. 97.811(c) or (d), Sec. 
97.823, Sec. 97.824, Sec. 97.825, Sec. 97.827, or Sec. 97.828 or 
paragraph (c) or (d) of this section.
    (c) At any time after the allowance transfer deadline for the last 
control period for which a State NOX Ozone Season Group 2 
trading budget is set forth in Sec. 97.810(a) for a given State and 
after completion of the procedures under paragraphs (d)(1) and (2) of 
this section, the Administrator may record a transfer of any CSAPR 
NOX Ozone Season Group 2 allowances held in the compliance 
account for a source in such State (or Indian country within the borders 
of such State) to a general account identified or established by the 
Administrator with the source's designated representative as the 
authorized account representative and with the owners and operators of 
the source (as indicated on the certificate of representation for the 
source) as the persons represented by the authorized account 
representative. The Administrator will notify the designated 
representative not less than 15 days before making such a transfer.
    (d) Notwithstanding any other provision of this subpart, part 52 of 
this chapter, or any SIP revision approved under Sec. 52.38(b)(8) or 
(9) of this chapter:
    (1) By August 13, 2021, the Administrator will temporarily suspend 
acceptance of CSAPR NOX Ozone Season Group 2 allowance 
transfers submitted under Sec. 97.822 and, before resuming acceptance 
of such transfers, will take the following actions:
    (i) The Administrator will determine each of the following values:
    (A) The total amount of CSAPR NOX Ozone Season Group 2 
allowances allocated for the control periods in 2017 through 2020 
attributable to the States listed in Sec. 52.38(b)(2)(iv) of this 
chapter (and Indian country within the borders of such States), computed 
as the sum of the State NOX Ozone Season Group 2 trading 
budgets under Sec. 97.810(a) for such States for all such control 
periods plus the product of 1.5 multiplied by the sum of the variability 
limits under Sec. 97.810(b) for such States for the control period in 
2017.
    (B) The total tons of NOX emissions reported in 
accordance with Sec. Sec. 97.806(b) and 97.830 through 97.835 for all 
CSAPR NOX Ozone Season Group 2 units at CSAPR NOX 
Ozone Season Group 2 sources in the States listed in Sec. 
52.38(b)(2)(iv) of this chapter (and Indian country within the borders 
of such States) for the control periods in 2017 through 2020.
    (C) The full-season CSAPR NOX Ozone Season Group 3 
allowance bank target, computed as the sum for all States listed in 
Sec. 52.38(b)(2)(v) of this chapter of the variability limits under 
Sec. 97.1010(b) for such States for the control period in 2022.
    (D) A conversion factor, computed as the quotient, rounded down to 
the nearest whole number, of the remainder of the total amount of CSAPR 
NOX Ozone Season Group 2 allowances determined under 
paragraph (d)(1)(i)(A) of this section minus the total tons of 
NOX emissions determined under paragraph (d)(1)(i)(B) of this 
section divided by the full-season CSAPR NOX Ozone Season 
Group 3 allowance bank target determined under paragraph (d)(1)(i)(C) of 
this section.
    (E) The adjusted CSAPR NOX Ozone Season Group 3 allowance 
bank target, computed as the product, rounded to the nearest allowance, 
of the full-season CSAPR NOX Ozone Season Group 3 allowance 
bank target determined under paragraph (d)(1)(i)(C) of this section 
multiplied by a fraction whose numerator is the number of days from June 
29, 2021 through September 30, 2021, inclusive, and whose denominator is 
153.
    (ii) The Administrator will allocate CSAPR NOX Ozone 
Season Group 3 allowances for the control period in 2021

[[Page 441]]

to sources in States listed in Sec. 52.38(b)(2)(v) of this chapter (and 
Indian country within the borders of such States) as follows:
    (A) The Administrator will determine for each such source the 
source's maximum share, computed as the quotient, rounded down to the 
nearest whole number, of the amount of CSAPR NOX Ozone Season 
Group 2 allowances allocated for control periods before 2021 held in the 
source's compliance account divided by the conversion factor determined 
under paragraph (d)(1)(i)(D) of this section.
    (B) The Administrator will determine a source allocation scaling 
factor, computed as the lesser of 1.0000 or the quotient, expressed to 
four decimal places, of the adjusted CSAPR NOX Ozone Season 
Group 3 allowance bank target determined under paragraph (d)(1)(i)(E) of 
this section divided by the sum for all such sources of the maximum 
shares under paragraph (d)(1)(ii)(A) of this section.
    (C) The Administrator will allocate to each such source an amount of 
CSAPR NOX Ozone Season Group 3 allowances computed as the 
product, rounded to the nearest allowance, of such source's maximum 
share under paragraph (d)(1)(ii)(A) of this section multiplied by the 
source allocation scaling factor determined under paragraph 
(d)(1)(ii)(B) of this section.
    (iii) If the sum for all sources of the allocations under paragraph 
(d)(1)(ii)(C) of this section is less than the adjusted CSAPR 
NOX Ozone Season Group 3 allowance bank target determined 
under paragraph (d)(1)(i)(E) of this section, the Administrator will 
allocate CSAPR NOX Ozone Season Group 3 allowances for the 
control period in 2021 to general accounts as follows:
    (A) The Administrator will determine for each general account the 
account's maximum share, computed as the quotient, rounded down to the 
nearest whole number, of the amount of CSAPR NOX Ozone Season 
Group 2 allowances allocated for control periods before 2021 held in the 
account divided by the conversion factor determined under paragraph 
(d)(1)(i)(D) of this section.
    (B) The Administrator will determine a general account allocation 
scaling factor, computed as the lesser of 1.0000 or the quotient, 
expressed to four decimal places, of the remainder of the adjusted CSAPR 
NOX Ozone Season Group 3 allowance bank target determined 
under paragraph (d)(1)(i)(E) of this section minus the sum for all 
sources of the allocations under paragraph (d)(1)(ii)(C) of this section 
divided by the sum for all general accounts of the maximum shares under 
paragraph (d)(1)(iii)(A) of this section.
    (C) The Administrator will allocate to each general account an 
amount of CSAPR NOX Ozone Season Group 3 allowances computed 
as the product, rounded to the nearest allowance, of such account's 
maximum share under paragraph (d)(1)(iii)(A) of this section multiplied 
by the general account allocation scaling factor determined under 
paragraph (d)(1)(iii)(B) of this section.
    (iv) For the compliance account of each source, and for each general 
account, to which an amount of CSAPR NOX Ozone Season Group 3 
allowances greater than zero is allocated under paragraph (d)(1)(ii)(C) 
or (d)(1)(iii)(C) of this section, respectively:
    (A) The Administrator will determine the amount of CSAPR 
NOX Ozone Season Group 2 allowances required to be deducted 
from the account, computed as the product of the amount of CSAPR 
NOX Ozone Season Group 3 allowances allocated to the source 
or general account under paragraph (d)(1)(ii)(C) or (d)(1)(iii)(C) of 
this section multiplied by the conversion factor determined under 
paragraph (d)(1)(i)(D) of this section. The Administrator will deduct 
CSAPR NOX Ozone Season Group 2 allowances allocated for 
control periods before 2021 from the account on a first-in, first-out 
basis in the order set forth in Sec. 97.824(c)(2)(i) and (ii).
    (B) The Administrator will record in the account the allocations of 
CSAPR NOX Ozone Season Group 3 allowances under paragraph 
(d)(1)(ii)(C) or (d)(1)(iii)(C) of this section and the deductions of 
CSAPR NOX Ozone Season Group 2 allowances under paragraph 
(d)(1)(iv)(A) of this section.
    (2)(i) During the period beginning February 1, 2022 and ending 
February 28, 2022, the designated representative

[[Page 442]]

for a source in a State listed in Sec. 52.38(b)(2)(v) of this chapter 
(or Indian country within the borders of such a State) may request that 
the Administrator allocate additional CSAPR NOX Ozone Season 
Group 3 allowances for the control period in 2021 to the source pursuant 
to paragraph (d)(2)(ii) of this section. Any such request shall be 
submitted to the Administrator electronically at the email address 
[email protected].
    (ii) For each source covered by a request under paragraph (d)(2)(i) 
of this section, as soon as practicable on or after March 1, 2022, the 
Administrator will deduct from the source's compliance account, on a 
first-in, first-out basis in the order set forth in Sec. 
97.824(c)(2)(i) and (ii), the maximum number of sets of 18 CSAPR 
NOX Ozone Season Group 2 allowances allocated for control 
periods before 2021 available in the compliance account. The 
Administrator will then allocate to the source one CSAPR NOX 
Ozone Season Group 3 allowance for the control period in 2021 for each 
set of 18 CSAPR NOX Ozone Season Group 2 allowances deducted. 
The Administrator will record the allocations and deductions under this 
paragraph in the source's compliance account.
    (3) After the Administrator has carried out the procedures set forth 
in paragraph (d)(1) of this section, upon any determination that would 
otherwise result in the initial recordation of a given number of CSAPR 
NOX Ozone Season Group 2 allowances in the compliance account 
for a source in a State listed in Sec. 52.38(b)(2)(v) of this chapter 
(or Indian country within the borders of such a State), the 
Administrator will not record such CSAPR NOX Ozone Season 
Group 2 allowances but instead will allocate and record in such account 
an amount of CSAPR NOX Ozone Season Group 3 allowances for 
the control period in 2021 computed as the quotient, rounded up to the 
nearest allowance, of such given number of CSAPR NOX Ozone 
Season Group 2 allowances divided by the conversion factor determined 
under paragraph (d)(1)(i)(D) of this section.
    (e) Notwithstanding any other provision of this subpart or any SIP 
revision approved under Sec. 52.38(b)(8) or (9) of this chapter, CSAPR 
NOX Ozone Season Group 3 allowances may be used to satisfy 
requirements to hold CSAPR NOX Ozone Season Group 2 
allowances under this subpart as follows, provided that nothing in this 
paragraph alters the time as of which any such allowance holding 
requirement must be met or limits any consequence of a failure to timely 
meet any such allowance holding requirement:
    (1) Except as provided in paragraph (e)(2) of this section, after 
the Administrator has carried out the procedures set forth in paragraph 
(d)(1) of this section, the owner or operator of a CSAPR NOX 
Ozone Season Group 2 source in a State listed in Sec. 52.38(b)(2)(iv) 
of this chapter (or Indian country within the borders of such a State) 
may satisfy a requirement to hold a given number of CSAPR NOX 
Ozone Season Group 2 allowances for the control period in a year from 
2017 through 2020 by holding instead, in a general account established 
for this sole purpose, an amount of CSAPR NOX Ozone Season 
Group 3 allowances for the control period in 2021 (or any later control 
period for which the allowance transfer deadline defined in Sec. 
97.1002 has passed) computed as the quotient, rounded up to the nearest 
allowance, of such given number of CSAPR NOX Ozone Season 
Group 2 allowances divided by the conversion factor determined under 
paragraph (d)(1)(i)(D) of this section.
    (2) CSAPR NOX Ozone Season Group 3 allowances may not be 
used to satisfy requirements to surrender CSAPR NOX Ozone 
Season Group 2 allowances under Sec. 97.811(d).

                                * * * * *

    (e) Notwithstanding any other provision of this subpart, part 52 of 
this chapter, or any SIP revision approved under Sec. 52.38(b)(8) or 
(9) of this chapter:
    (1) By September 18, 2023, the Administrator will temporarily 
suspend acceptance of CSAPR NOX Ozone Season Group 2 
allowance transfers submitted under Sec. 97.822 and, before resuming 
acceptance of such transfers, will take the following actions with 
regard to every general account and every compliance account except a 
compliance account for a CSAPR NOX Ozone Season Group 2 
source in a State listed in Sec. 52.38(b)(2)(ii)(A) of this chapter 
(and Indian country within the borders of such a State):
    (i) The Administrator will deduct all CSAPR NOX Ozone 
Season Group 2 allowances allocated for the control periods in 2017 
through 2022 from each such account.
    (ii) The Administrator will determine a conversion factor equal to 
the greater of 1.0000 or the quotient, expressed to four decimal places, 
of--
    (A) The sum of all CSAPR NOX Ozone Season Group 2 
allowances deducted from all such accounts under paragraph (e)(1)(i) of 
this section; divided by
    (B) The product of the sum of the variability limits for the control 
period in 2024 under Sec. 97.1010(e) for all States listed in Sec. 
52.38(b)(2)(iii)(B) and (C) of this chapter multiplied by a fraction 
whose numerator is the number of days from August 4, 2023 through 
September 30, 2023, inclusive, and whose denominator is 153.
    (iii) The Administrator will allocate and record in each such 
account an amount of CSAPR NOX Ozone Season Group 3 
allowances for the control period in 2023 computed as the quotient, 
rounded up to the nearest allowance, of the number of CSAPR 
NOX Ozone Season Group 2 allowances deducted from such 
account under paragraph (e)(1)(i) of this section divided by the 
conversion factor determined under paragraph (e)(1)(ii) of this section, 
except as provided in paragraph (e)(1)(iv) or (v) of this section.
    (iv) Where, pursuant to paragraph (e)(1)(i) of this section, the 
Administrator deducts CSAPR NOX Ozone Season Group 2 
allowances from the compliance account for a source in a State not 
listed in Sec. 52.38(b)(2)(iii) of this chapter (and Indian country 
within the borders of such a State), the Administrator will not record 
CSAPR NOX Ozone Season Group 3 allowances in that compliance 
account but instead will allocate and record the amount of CSAPR 
NOX Ozone Season Group 3 allowances for the control period in 
2023 computed for such source in accordance with paragraph (e)(1)(iii) 
of this section in a general account identified by the designated 
representative for such source, provided that if the designated 
representative fails to identify such a general account in a submission 
to the Administrator by September 18, 2023, the Administrator may record 
such CSAPR NOX Ozone Season Group 3 allowances in a general 
account identified or established by the Administrator with the 
designated representative as the authorized account representative and 
with the owners and operators of such source (as indicated on the 
certificate of representation for the source) as the persons represented 
by the authorized account representative.
    (v)(A) In computing any amounts of CSAPR NOX Ozone Season 
Group 3 allowances to be allocated to and recorded in general accounts 
under paragraph (e)(1)(iii) of this section, the Administrator may group 
multiple general accounts whose ownership interests are held by the same 
or related persons or entities and treat the group of accounts as a 
single account for purposes of such computation.
    (B) Following a computation for a group of general accounts in 
accordance with paragraph (e)(1)(v)(A) of this section, the 
Administrator will allocate to and record in each individual account in 
such group a proportional share of the quantity of CSAPR NOX 
Ozone Season Group 3 allowances computed for such group, basing such 
shares on the respective quantities of CSAPR NOX Ozone Season 
Group 2 allowances removed from such individual accounts under paragraph 
(e)(1)(i) of this section.
    (C) In determining the proportional shares under paragraph 
(e)(1)(v)(B) of this section, the Administrator may employ any 
reasonable adjustment methodology to truncate or

[[Page 444]]

round each such share up or down to a whole number and to cause the 
total of such whole numbers to equal the amount of CSAPR NOX 
Ozone Season Group 3 allowances computed for such group of accounts in 
accordance with paragraph (e)(1)(v)(A) of this section, even where such 
adjustments cause the numbers of CSAPR NOX Ozone Season Group 
3 allowances allocated to some individual accounts to equal zero.
    (2) After the Administrator has carried out the procedures set forth 
in paragraph (e)(1) of this section, upon any determination that would 
otherwise result in the initial recordation of a given number of CSAPR 
NOX Ozone Season Group 2 allowances in the compliance account 
for a source in a State listed in Sec. 52.38(b)(2)(iii)(B) of this 
chapter (and Indian country within the borders of such a State), the 
Administrator will not record such CSAPR NOX Ozone Season 
Group 2 allowances but instead will allocate and record in such account 
an amount of CSAPR NOX Ozone Season Group 3 allowances for 
the control period in 2023 computed as the quotient, rounded up to the 
nearest allowance, of such given number of CSAPR NOX Ozone 
Season Group 2 allowances divided by the conversion factor determined 
under paragraph (e)(1)(ii) of this section.
    (f) * * *
    (1) After the Administrator has carried out the procedures set forth 
in paragraph (d)(1) of this section, the owner or operator of a CSAPR 
NOX Ozone Season Group 2 source in a State listed in Sec. 
52.38(b)(2)(ii)(B) of this chapter (and Indian country within the 
borders of such a State) may satisfy a requirement to hold a given 
number of CSAPR NOX Ozone Season Group 2 allowances for a 
control period in 2017 through 2020 by holding instead, in a general 
account established for this sole purpose, an amount of CSAPR 
NOX Ozone Season Group 3 allowances for the control period in 
2021 (or any later control period for which the allowance transfer 
deadline defined in Sec. 97.1002 has passed) computed as the quotient,

system may be used under the CSAPR NOX Ozone Season Group 2 
Trading Program for a period not to exceed 120 days after receipt by the 
Administrator of the complete certification application for the 
monitoring system under paragraph (d)(3)(ii) of this section. Data 
measured and recorded by the provisionally certified monitoring system, 
in accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the Administrator does not 
invalidate the provisional certification by issuing a notice of 
disapproval within 120 days of the date of receipt of the complete 
certification application by the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of

Sec. 97.832  Monitoring system out-of-control periods.

    (a) General provisions. Whenever any monitoring system fails to meet 
the quality-assurance and quality-control requirements or data 
validation requirements of part 75 of this chapter, data shall be 
substituted using the applicable missing data procedures in subpart D or 
subpart H of, or appendix D or appendix E to, part 75 of this chapter.
    (b) Audit decertification. Whenever both an audit of a monitoring 
system and a review of the initial certification or recertification 
application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.831 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.831 for 
each disapproved monitoring system.

shall comply with the requirement to have a designated representative, 
and may have an alternate designated representative, in accordance with 
Sec. Sec. 97.913 through 97.918.
    (b) Emissions monitoring, reporting, and recordkeeping requirements. 
(1) The owners and operators, and the designated representative, of each 
Texas SO2 Trading Program source and each Texas 
SO2 Trading Program unit at the source shall comply with the 
monitoring, reporting, and recordkeeping requirements of Sec. Sec. 
97.930 through 97.935.
    (2) The emissions data determined in accordance with Sec. Sec. 
97.930 through 97.935 shall be used to calculate allocations of Texas 
SO2 Trading Program allowances under Sec. 97.912 and to 
determine compliance with the Texas SO2 Trading Program 
emissions limitation and assurance provisions under paragraph (c) of 
this section, provided that, for each monitoring location from which 
mass emissions are reported, the mass emissions amount used in 
calculating such allocations and determining such compliance shall be 
the mass emissions amount for the monitoring location determined in 
accordance with Sec. Sec. 97.930 through 97.935 and rounded to the 
nearest ton, with any fraction of a ton less than 0.50 being deemed to 
be zero and any fraction of a ton greater than or equal to 0.50 being 
deemed to be a whole ton.
    (c) SO2 emissions requirements--(1) Texas SO2 Trading Program 
emissions limitation. (i) As of the allowance transfer deadline for a 
control period in a given year, the owners and operators of each Texas 
SO2 Trading Program source and each Texas SO2 
Trading Program unit at the source shall hold, in the source's 
compliance account, Texas SO2 Trading Program allowances 
available for deduction for such control period under Sec. 97.924(a) in 
an amount not less than the tons of total SO2 emissions for 
such control period from all Texas SO2 Trading Program units 
at the source.
    (ii) If total SO2 emissions during a control period in a 
given year from the Texas SO2 Trading Program units at a 
Texas SO2 Trading Program source are in excess of the Texas 
SO2 Trading Program emissions limitation set forth in 
paragraph (c)(1)(i) of this section, then:
    (A) The owners and operators of the source and each Texas 
SO2 Trading Program unit at the source shall hold the Texas 
SO2 Trading Program allowances required for deduction under 
Sec. 97.924(d); and

[[Page 459]]

    (B) The owners and operators of the source and each Texas 
SO2 Trading Program unit at the source shall pay any fine, 
penalty, or assessment or comply with any other remedy imposed, for the 
same violations, under the Clean Air Act, and each ton of such excess 
emissions and each day of such control period shall constitute a 
separate violation of this subpart and the Clean Air Act.
    (2) Texas SO2 Trading Program assurance provisions. (i) If total 
SO2 emissions during a control period in a given year from 
all Texas SO2 Trading Program units at Texas SO2 
Trading Program sources exceed the State assurance level, then the 
owners and operators of such sources and units in each group of one or 
more sources and units having a common designated representative for 
such control period, where the common designated representative's share 
of such SO2 emissions during such control period exceeds the 
common designated representative's assurance level for such control 
period, shall hold (in the assurance account established for the owners 
and operators of such group) Texas SO2 Trading Program 
allowances available for deduction for such control period under Sec. 
97.925(a) in an amount equal to two times the product (rounded to the 
nearest whole number), as determined by the Administrator in accordance 
with Sec. 97.925(b), of multiplying--
    (A) The quotient of the amount by which the common designated 
representative's share of such SO2 emissions exceeds the 
common designated representative's assurance level divided by the sum of 
the amounts, determined for all common designated representatives for 
such sources and units for such control period, by which each common 
designated representative's share of such SO2 emissions 
exceeds the respective common designated representative's assurance 
level; and
    (B) The amount by which total SO2 emissions from all 
Texas SO2 Trading Program units at Texas SO2 
Trading Program sources for such control period exceed the State 
assurance level.
    (ii) The owners and operators shall hold the Texas SO2 
Trading Program allowances required under paragraph (c)(2)(i) of this 
section, as of midnight of November 1 (if it is a business day), or 
midnight of the first business day thereafter (if November 1 is not a 
business day), immediately after the year of such control period.
    (iii) Total SO2 emissions from all Texas SO2 
Trading Program units at Texas SO2 Trading Program sources 
during a control period in a given year exceed the State assurance level 
if such total SO2 emissions exceed the sum, for such control 
period, of the Texas SO2 Trading Program budget under Sec. 
97.910(a)(1) and the variability limit under Sec. 97.910(b).
    (iv) It shall not be a violation of this subpart or of the Clean Air 
Act if total SO2 emissions from all Texas SO2 
Trading Program units at Texas SO2 Trading Program sources 
during a control period exceed the State assurance level or if a common 
designated representative's share of total SO2 emissions from 
the Texas SO2 Trading Program units at Texas SO2 
Trading Program sources during a control period exceeds the common 
designated representative's assurance level.
    (v) To the extent the owners and operators fail to hold Texas 
SO2 Trading Program allowances for a control period in a 
given year in accordance with paragraphs (c)(2)(i) through (iii) of this 
section,
    (A) The owners and operators shall pay any fine, penalty, or 
assessment or comply with any other remedy imposed under the Clean Air 
Act; and
    (B) Each Texas SO2 Trading Program allowance that the 
owners and operators fail to hold for such control period in accordance 
with paragraphs (c)(2)(i) through (iii) of this section and each day of 
such control period shall constitute a separate violation of this 
subpart and the Clean Air Act.
    (3) Compliance periods. (i) A Texas SO2 Trading Program 
unit shall be subject to the requirements under paragraph (c)(1) of this 
section for the control period starting on January 1, 2019 and for each 
control period thereafter.
    (ii) A Texas SO2 Trading Program unit shall be subject to 
the requirements under paragraph (c)(2) of this section for the control 
period starting

[[Page 460]]

on January 1, 2021 and for each control period thereafter.
    (4) Vintage of Texas SO2 Trading Program allowances held for 
compliance. (i) A Texas SO2 Trading Program allowance held 
for compliance with the requirements under paragraph (c)(1)(i) of this 
section for a control period in a given year must be a Texas 
SO2 Trading Program allowance that was allocated for such 
control period or a control period in a prior year.
    (ii) A Texas SO2 Trading Program allowance held for 
compliance with the requirements under paragraphs (c)(1)(ii)(A) and 
(c)(2)(i) through (iii) of this section for a control period in a given 
year must be a Texas SO2 Trading Program allowance that was 
allocated for a control period in a prior year or the control period in 
the given year or in the immediately following year.
    (5) Allowance Management System requirements. Each Texas 
SO2 Trading Program allowance shall be held in, deducted 
from, or transferred into, out of, or between Allowance Management 
System accounts in accordance with this subpart.
    (6) Limited authorization. A Texas SO2 Trading Program 
allowance is a limited authorization to emit one ton of SO2 
during the control period in one year. Such authorization is limited in 
its use and duration as follows:
    (i) Such authorization shall only be used in accordance with the 
Texas SO2 Trading Program; and
    (ii) Notwithstanding any other provision of this subpart, the 
Administrator has the authority to terminate or limit the use and 
duration of such authorization to the extent the Administrator 
determines is necessary or appropriate to implement any provision of the 
Clean Air Act.
    (7) Property right. A Texas SO2 Trading Program allowance 
does not constitute a property right.
    (d) Title V permit requirements. (1) No title V permit revision 
shall be required for any allocation, holding, deduction, or transfer of 
Texas SO2 Trading Program allowances in accordance with this 
subpart.
    (2) A description of whether a unit is required to monitor and 
report SO2 emissions using a continuous emission monitoring 
system (under subpart B of part 75 of this chapter), an excepted 
monitoring system (under appendices D and E to part 75 of this chapter), 
a low mass emissions excepted monitoring methodology (under Sec. 75.19 
of this chapter), or an alternative monitoring system (under subpart E 
of part 75 of this chapter) in accordance with Sec. Sec. 97.930 through 
97.935 may be added to, or changed in, a title V permit using minor 
permit modification procedures in accordance with Sec. Sec. 70.7(e)(2) 
and 71.7(e)(1) of this chapter, provided that the requirements 
applicable to the described monitoring and reporting (as added or 
changed, respectively) are already incorporated in such permit. This 
paragraph explicitly provides that the addition of, or change to, a 
unit's description as described in the prior sentence is eligible for 
minor permit modification procedures in accordance with Sec. Sec. 
70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.
    (e) Additional recordkeeping and reporting requirements. (1) Unless 
otherwise provided, the owners and operators of each Texas 
SO2 Trading Program source and each Texas SO2 
Trading Program unit at the source shall keep on site at the source each 
of the following documents (in hardcopy or electronic format) for a 
period of 5 years from the date the document is created. This period may 
be extended for cause, at any time before the end of 5 years, in writing 
by the Administrator.
    (i) The certificate of representation under Sec. 97.916 for the 
designated representative for the source and each Texas SO2 
Trading Program unit at the source and all documents that demonstrate 
the truth of the statements in the certificate of representation; 
provided that the certificate and documents shall be retained on site at

    (2) The designated representative of a Texas SO2 Trading 
Program source and each Texas SO2 Trading Program unit at the 
source shall make all submissions required under the Texas 
SO2 Trading Program, except as provided in Sec. 97.918. This 
requirement does not change, create an exemption from, or otherwise 
affect the responsible official submission requirements under a title V 
operating permit program in parts 70 and 71 of this chapter.
    (f) Liability. (1) Any provision of the Texas SO2 Trading 
Program that applies to a Texas SO2 Trading Program source or 
the designated representative of a Texas SO2 Trading Program

apply to the owners and operators of such unit.
    (g) Effect on other authorities. No provision of the Texas 
SO2 Trading Program or exemption under Sec. 97.905 shall be 
construed as exempting or excluding the owners and operators, and the 
designated representative, of a Texas SO2 Trading Program 
source or Texas SO2 Trading Program unit from compliance with 
any other provision of the applicable, approved State implementation 
plan, a federally enforceable permit, or the Clean Air Act.

[[Page 463]]

each control period in 2019 and thereafter, if the Administrator 
determines that Texas SO2 Trading Program allowances were 
incorrectly allocated under paragraph (a) of this section, or under a 
provision of a SIP revision approved by the Administrator, then the 
Administrator will notify the designated representative of the recipient 
and will act in accordance with the procedures set forth in paragraphs 
(c)(2) through (5) of this section:
    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such Texas SO2 Trading 
Program allowances under Sec. 97.921.
    (3) If the Administrator already recorded such Texas SO2 
Trading Program allowances under Sec. 97.921 and if the Administrator 
makes the determination under paragraph (c)(1) of this section before 
making deductions for the source that includes such recipient under 
Sec. 97.924(b) for such control period, then the Administrator will 
deduct from the account in which such Texas SO2 Trading 
Program allowances were recorded an amount of Texas SO2 
Trading Program allowances allocated for the same or a prior control 
period equal to the amount of such already recorded Texas SO2 
Trading Program allowances. The authorized account representative shall 
ensure that there are sufficient Texas SO2 Trading Program 
allowances in such account for completion of the deduction.
    (4) If the Administrator already recorded such Texas SO2 
Trading Program allowances under Sec. 97.921 and if the Administrator 
makes the determination under paragraph (c)(1) of this section after 
making deductions for the source that includes such recipient under 
Sec. 97.924(b) for such control period, then the Administrator will not 
make any deduction to take account of such already recorded Texas 
SO2 Trading Program allowances.
    (5) With regard to the Texas SO2 Trading Program 
allowances that are not recorded, or that are deducted as an incorrect 
allocation, in accordance with paragraphs (c)(2) and (3) of this 
section, the Administrator will transfer such Texas SO2 
Trading Program allowances to the Supplemental Allowance Pool for 
potential allocation in accordance with Sec. 97.912.

Sec. 97.912  Texas SO2 Trading Program Supplemental Allowance Pool.

    (a) For the control periods in 2019 and 2020, the Administrator will 
allocate Texas SO2 Trading Program allowances from the Texas 
SO2 Trading Program Supplemental Allowance Pool as follows:
    (1) No later than February 15, 2020 and February 15, 2021, the 
Administrator will review all the quarterly SO2 emissions 
reports provided under Sec. 97.934(d) for each Texas SO2 
Trading Program unit for the previous control period. The Administrator 
will identify each Texas SO2 Trading Program source for which 
the total amount of emissions reported for the units at the source for 
that control period exceeds the total amount of allowances allocated to 
the units at the source for that control period under Sec. 97.911 and 
recorded under Sec. 97.921.
    (2) For each Texas SO2 Trading Program source identified 
under paragraph (a)(1) of this section, the Administrator will calculate 
the amount by which the total amount of reported emissions for that 
control period exceeds the total amount of allowances allocated for that 
control period under Sec. 97.911 and recorded under Sec. 97.921.
    (3)(i) For Coleto Creek (ORIS 6178), if the source is identified 
under paragraph (a)(1) of this section, the Administrator will allocate 
and record in the source's compliance account an amount of allowances 
from the Supplemental Allowance Pool equal to the lesser of the amount 
calculated for the source under paragraph (a)(2) of this section or the 
total number of allowances in the Supplemental Allowance Pool available 
for allocation under paragraph (d) of this section.
    (ii) For any Texas SO2 Trading Program sources identified 
under paragraph (a)(1) of this section other than Coleto Creek (ORIS 
6178), the Administrator will allocate and record allowances from the 
Supplemental Allowance Pool as follows:

[[Page 464]]

    (A) If the total for all such sources of the amounts calculated 
under paragraph (a)(2) of this section is less than or equal to the 
total number of allowances in the Supplemental Allowance Pool available 
for allocation under paragraph (d) of this section that remain after any 
allocation under paragraph (a)(3)(i) of this section, then the 
Administrator will allocate and record in the compliance account for 
each such source an amount of allowances from the Supplemental Allowance 
Pool equal to the amount calculated for the source under paragraph 
(a)(2) of this section.
    (B) If the total for all such sources of the amounts calculated 
under paragraph (a)(2) of this section is greater than the total number 
of allowances in the Supplemental Allowance Pool available for 
allocation under paragraph (d) of this section that remain after any 
allocation under paragraph (a)(3)(i) of this section, then the 
Administrator will calculate each such source's allocation of allowances 
from the Supplemental Allowance Pool by dividing the amount calculated 
under paragraph (a)(2) of this section for the source by the sum of the 
amounts calculated under paragraph (a)(2) of this section for all such 
sources, then multiplying by the number of allowances in the 
Supplemental Allowance Pool available for allocation under paragraph (d) 
of this section that remain after any allocation under paragraph 
(a)(3)(i) of this section and rounding to the nearest allowance. The 
Administrator will adjust the sources' allocations up or down by one 
allowance, starting with the largest allocation and continuing in 
descending order, as necessary to cause the sum of the sources' 
allocations to equal the total number of allowances in the Supplemental 
Allowance Pool available for allocation under paragraph (d) of this 
section that remain after any allocation under paragraph (a)(3)(i) of 
this section. The Administrator will then record the calculated 
allocations of allowances in the applicable compliance accounts.
    (iii) Any unallocated allowances remaining in the Supplemental 
Allowance Pool after the allocations determined under paragraphs 
(a)(3)(i) and (ii) of this section will be maintained in the 
Supplemental Allowance Pool. These allowances will be available for 
allocation by the Administrator in subsequent control periods to the 
extent consistent with paragraph (d) of this section.
    (b) For each control period in 2021 and thereafter, the 
Administrator will allocate Texas SO2 Trading Program 
allowances from the Texas SO2 Trading Program Supplemental 
Allowance Pool as follows:
    (1) For each control period, the Administrator will assign each 
Texas SO2 Trading Program unit to an affiliated ownership 
group reflecting the unit's ownership as of December 31 of the control 
period. The affiliated ownership group assignments for each control 
period will be as shown in Sec. 97.911(a)(1) except that the 
Administrator will revise the assignments, based on the information 
required to be submitted in accordance with Sec. 97.915(c) and any 
other information available to the Administrator, as necessary to 
reflect any ownership transfer resulting in a 50% or greater ownership 
share of a unit being held by a new owner that the Administrator 
determines is not affiliated with the previous holder of a 50% or 
greater ownership share of the unit.
    (2) No later than May 1, 2022 and May 1 of each year thereafter, the 
Administrator will review all the quarterly SO2 emissions 
reports provided under Sec. 97.934(d) for each Texas SO2 
Trading Program unit for the previous control period. The Administrator 
will identify each affiliated ownership group of Texas SO2 
Trading Program units as of December 31 of such control period for which 
the total amount of emissions reported for the units in the group for 
that control period exceeds the total amount of allowances allocated to 
the units in the group for that control period under Sec. 97.911 and 
recorded under Sec. 97.921.
    (3) For each affiliated ownership group of Texas SO2 
Trading Program units identified under paragraph (b)(2) of this section, 
the Administrator will calculate the amount by which the total amount of 
reported emissions for that control period exceeds the total amount of 
allowances allocated for

[[Page 465]]

that control period under Sec. 97.911 and recorded under Sec. 97.921.
    (4)(i) The Administrator will allocate and record allowances from 
the Supplemental Allowance Pool as follows:
    (A) If the total for all such affiliated ownership groups of the 
amounts calculated under paragraph (b)(3) of this section is less than 
or equal to the total number of allowances in the Supplemental Allowance 
Pool available for allocation under paragraph (d) of this section, then 
each such group's allocation of allowances from the Supplemental 
Allowance Pool shall equal to the amount calculated for the group under 
paragraph (b)(3) of this section.
    (B) If the total for all such affiliated ownership groups of the 
amounts calculated under paragraph (b)(3) of this section is greater 
than the total number of allowances in the Supplemental Allowance Pool 
available for allocation under paragraph (d) of this section, then the 
Administrator will calculate each such group's allocation of allowances 
from the Supplemental Allowance Pool by dividing the amount calculated 
under paragraph (b)(3) of this section for the group by the sum of the 
amounts calculated under paragraph (b)(3) of this section for all such 
groups, then multiplying by the number of allowances in the Supplemental 
Allowance Pool available for allocation under paragraph (d) of this 
section and rounding to the nearest allowance. The Administrator will 
adjust the groups' allocations up or down by one allowance, starting 
with the largest allocation and continuing in descending order, as 
necessary to cause the sum of the groups' allocations to equal the total 
number of allowances in the Supplemental Allowance Pool available for 
allocation under paragraph (d) of this section.
    (C) When an affiliated ownership group receives an allocation of 
allowances under paragraph (b)(4)(i)(A) or (B) of this section, each 
source in the group whose emissions during the control period for which 
allowances are being allocated exceed the amount of allowances allocated 
to the source under Sec. 97.911 and recorded under Sec. 97.921 will 
receive a share of the group's allocation. The Administrator will 
compute each such source's share by dividing the amount of the source's 
emissions during the control period exceeding the source's allocation 
under Sec. 97.911 by the sum for all such sources of the amounts of the 
sources' emissions during the control period exceeding the sources' 
allocations under Sec. 97.911, then multiplying by the group's 
allocation under paragraph (b)(4)(i)(A) or (B) of this section and 
rounding to the nearest allowance. The Administrator will adjust the 
sources' allocations up or down by one allowance, starting with the 
largest allocation and continuing in descending order, as necessary to 
cause the sum of the sources' allocations to equal the group's 
allocation. The Administrator will then record the calculated 
allocations of allowances in the applicable sources' compliance 
accounts.
    (ii) Any unallocated allowances remaining in the Supplemental 
Allowance Pool after the allocations determined under paragraph 
(b)(4)(i) of this section will be maintained in the Supplemental 
Allowance Pool. These allowances will be available for allocation by the 
Administrator in subsequent control periods to the extent consistent 
with paragraph (d) of this section.
    (c) The Administrator will notify the designated representative of 
each Texas SO2 Trading Program source when the allowances 
from the Supplemental Allowance Pool have been recorded.
    (d) The total amount of allowances in the Supplemental Allowance 
Pool available for allocation for a control period is equal to the sum 
of the Supplemental Allowance Pool budget under Sec. 97.910(a)(2), any 
allowances from retired units pursuant to Sec. 97.911(a)(2) and from 
corrections pursuant to Sec. 97.911(c)(5), and any allowances 
maintained in the Supplemental Allowance Pool pursuant to paragraph 
(a)(3)(iii) or (b)(4)(ii) of this section, provided that if the number 
of allowances in the Supplemental Allowance Pool exceeds the applicable 
limit for the control period under paragraph (d)(1) or (d)(2) of this 
section, then the Administrator may only allocate allowances up to such 
applicable limit.

[[Page 466]]

    (1) For the control periods in 2019 and 2020, the total amount of 
allowances allocated from the Supplemental Allowance Pool for a control 
period may not exceed by more than 44,711 tons the sum of the 
Supplemental Allowance Pool budget under Sec. 97.910(a)(2) and any 
portion of the Texas SO2 Trading Program budget under Sec. 
97.910(a)(1) not otherwise allocated for that control period under Sec. 
97.911(a)(1).
    (2) For each control period in 2021 and thereafter, the total amount 
of allowances allocated from the Supplemental Allowance Pool for a 
control period may not exceed the sum of the variability limit under 
Sec. 97.910(b) and any portion of the Texas SO2 Trading 
Program budget under Sec. 97.910(a)(1) not otherwise allocated for that 
control period under Sec. 97.911(a)(1).

application for a general account amending the list of persons having an 
ownership interest with respect to the Texas SO2 Trading 
Program allowances in the general account to include the change.

general account under paragraph (c)(1) of this section is received by

Sec. 97.924  Compliance with Texas SO2 Trading Program emissions limitations.

    (a) Availability for deduction for compliance. Texas SO2 
Trading Program allowances are available to be deducted for compliance 
with a source's Texas SO2 Trading Program emissions 
limitation for a control period in a given year only if the Texas 
SO2 Trading Program allowances:
    (1) Were allocated for such control period or a control period in a 
prior year; and
    (2) Are held in the source's compliance account as of the allowance 
transfer deadline for such control period.
    (b) Deductions for compliance. After the recordation, in accordance 
with Sec. 97.923, of Texas SO2 Trading Program allowance 
transfers submitted by the allowance transfer deadline for a control 
period in a given year, the Administrator will deduct from each source's 
compliance account Texas SO2 Trading Program allowances 
available under paragraph (a) of this section in order to determine 
whether the source meets the Texas SO2 Trading Program 
emissions limitation for such control period, as follows:
    (1) Until the amount of Texas SO2 Trading Program 
allowances deducted equals the number of tons of total SO2 
emissions from all Texas SO2 Trading Program units at the 
source for such control period; or
    (2) If there are insufficient Texas SO2 Trading Program 
allowances to complete the deductions in paragraph (b)(1) of this

available under paragraph (a) of this section remain in the compliance 
account.
    (c) Selection of Texas SO2 Trading Program allowances for 
deduction--(1) Identification by serial number. The designated 
representative for a source may request that specific Texas 
SO2 Trading Program allowances, identified by serial number, 
in the source's compliance account be deducted for emissions or excess 
emissions for a control period in a given year in accordance with 
paragraph (b) or (d) of this section. In order to be complete,

[[Page 476]]

such request shall be submitted to the Administrator by the allowance 
transfer deadline for such control period and include, in a format 
prescribed by the Administrator, the identification of the Texas 
SO2 Trading Program source and the appropriate serial 
numbers.
    (2) First-in, first-out. The Administrator will deduct Texas 
SO2 Trading Program allowances under paragraph (b) or (d) of 
this section from the source's compliance account in accordance with a 
complete request under paragraph (c)(1) of this section or, in the 
absence of such request or in the case of identification of an 
insufficient amount of Texas SO2 Trading Program allowances 
in such request, on a first-in, first-out accounting basis in the 
following order:
    (i) Any Texas SO2 Trading Program allowances that were 
recorded in the compliance account pursuant to Sec. 97.921 and not 
transferred out of the compliance account, in the order of recordation; 
and then
    (ii) Any other Texas SO2 Trading Program allowances that 
were transferred to and recorded in the compliance account pursuant to 
this subpart, in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the Texas SO2 Trading Program source has excess 
emissions, the Administrator will deduct from the source's compliance 
account an amount of Texas SO2 Trading Program allowances, 
allocated for a control period in a prior year or the control period in 
the year of the excess emissions or in the immediately following year, 
equal to three times the number of tons of the source's excess 
emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

allowances are available to be deducted for compliance with the Texas 
SO2 Trading Program assurance provisions for a control period 
in a given year by the owners and operators of a group of one or more 
Texas SO2 Trading Program sources and units only if the Texas 
SO2 Trading Program allowances:
    (1) Were allocated for a control period in a prior year or the 
control period in the given year or in the immediately following year; 
and
    (2) Are held in the assurance account, established by the

SO2 Trading Program sources and units under paragraph (b)(3) 
of this section, as of the deadline established in paragraph (b)(4) of 
this section.
    (b) Deductions for compliance. The Administrator will deduct Texas 
SO2 Trading Program allowances available under paragraph (a) 
of this section for compliance with the Texas SO2 Trading 
Program assurance provisions for a control period in a given year in 
accordance with the following procedures:
    (1) By August 1, 2022 and August 1 of each year thereafter, the 
Administrator will:
    (i) Calculate the total SO2 emissions from all Texas 
SO2 Trading Program units at Texas SO2 Trading 
Program sources during the control period in the year before the year of 
this calculation deadline and the amount, if any, by which such total 
SO2 emissions exceed the State assurance level as described 
in Sec. 97.906(c)(2)(iii); and
    (ii) If the results of the calculations required in paragraph 
(b)(1)(i) of this section indicate that total SO2 emissions 
exceed the State assurance level for such control period--
    (A) Calculate, for such control period and each common designated 
representative for such control period for a group of one or more Texas 
SO2 Trading Program sources and units, the common designated 
representative's share of the total SO2 emissions from all 
Texas SO2 Trading Program units at Texas SO2 
Trading Program sources, the common designated representative's 
assurance level, and the amount (if any) of Texas SO2 Trading 
Program

[[Page 477]]

allowances that the owners and operators of such group of sources and 
units must hold in accordance with the calculation formula in Sec. 
97.906(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the SO2 emissions 
from each Texas SO2 Trading Program source.
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.906(c)(2)(iii), Sec. Sec. 97.906(b) and 97.930 through 97.935, the 
definitions of ``common designated representative'', ``common designated 
representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.902, and the calculation formula in 
Sec. 97.906(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1 
immediately after the promulgation of such notice, the Administrator 
will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) The Administrator will establish one assurance account for each 
set of owners and operators referenced, in each notice of data 
availability required under paragraph (b)(2)(ii) of this section, as all 
of the owners and operators of a group of Texas SO2 Trading 
Program sources and units having a common designated representative for 
such control period and as being required to hold Texas SO2 
Trading Program allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate Texas SO2 
Trading Program sources and Texas SO2 Trading Program units 
under paragraph (b)(3) of this section a total amount of Texas 
SO2 Trading Program allowances, available for deduction under 
paragraph (a) of this section, equal to the amount such owners and 
operators are required to hold with regard to such sources and units as 
calculated by the Administrator and referenced in such notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.923, of Texas 
SO2 Trading Program allowance transfers submitted by midnight 
of such date, the Administrator will determine whether the owners and 
operators described in paragraph (b)(3) of this section hold, in the 
assurance account for the appropriate Texas SO2 Trading 
Program sources and Texas SO2 Trading Program units 
established under paragraph (b)(3) of this section, the amount of Texas 
SO2 Trading Program allowances available under paragraph (a) 
of this section that the owners and operators are required to hold with 
regard to such sources and units as calculated by the Administrator and 
referenced in the notice required in paragraph (b)(2)(ii) of this 
section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts

[[Page 478]]

of Texas SO2 Trading Program allowances that the owners and 
operators are required to hold in accordance with Sec. 97.906(c)(2)(i) 
for such control period shall continue to be such amounts as calculated 
by the Administrator and referenced in such notice required in paragraph 
(b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator will use the 
data as so revised to recalculate the amounts of Texas SO2 
Trading Program allowances that owners and operators are required to 
hold in accordance with the calculation formula in Sec. 97.906(c)(2)(i) 
for such control period with regard to the Texas SO2 Trading 
Program sources and Texas SO2 Trading Program units involved, 
provided that such litigation under part 78 of this chapter, or the 
proceeding under part 78 of this chapter that resulted in the decision 
appealed in such litigation under section 307 of the Clean Air Act, was 
initiated no later than 30 days after promulgation of such notice 
required in paragraph (b)(2)(ii) of this section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of Texas 
SO2 Trading Program allowances that the owners and operators 
are required to hold for such control period with regard to the Texas 
SO2 Trading Program sources and Texas SO2 Trading 
Program units involved--
    (A) Where the amount of Texas SO2 Trading Program 
allowances that the owners and operators are required to hold increases 
as a result of the use of all such revised data, the Administrator will 
establish a new, reasonable deadline on which the owners and operators 
shall hold the additional amount of Texas SO2 Trading Program 
allowances in the assurance account established by the Administrator for 
the appropriate Texas SO2 Trading Program sources and Texas 
SO2 Trading Program units under paragraph (b)(3) of this 
section. The owners' and operators' failure to hold such additional 
amount, as required, before the new deadline shall not be a violation of 
the Clean Air Act. The owners' and operators' failure to hold such 
additional amount, as required, as of the new deadline shall be a 
violation of the Clean Air Act. Each Texas SO2 Trading 
Program allowance that the owners and operators fail to hold as required 
as of the new deadline, and each day in such control period, shall be a 
separate violation of the Clean Air Act.
    (B) For the owners and operators for which the amount of Texas 
SO2 Trading Program allowances required to be held decreases 
as a result of the use of all such revised data, the Administrator will 
record, in all accounts from which Texas SO2 Trading Program 
allowances were transferred by such owners and operators for such 
control period to the assurance account established by the Administrator 
for the appropriate Texas SO2 Trading Program sources and 
Texas SO2 Trading Program units under paragraph (b)(3) of 
this section, a total amount of the Texas SO2 Trading Program 
allowances held in such assurance account equal to the amount of the 
decrease. If Texas SO2 Trading Program allowances were 
transferred to such assurance account from more than one account, the 
amount of Texas SO2 Trading Program allowances recorded in 
each such transferor account will be in proportion to the percentage of 
the total amount of Texas SO2 Trading Program allowances 
transferred to such assurance account for such control period from such 
transferor account.
    (C) Each Texas SO2 Trading Program allowance held under 
paragraph (b)(6)(iii)(A) of this section as a result of recalculation of 
requirements under the Texas SO2 Trading Program assurance 
provisions for such control period must be a Texas SO2 
Trading Program allowance allocated for a control period in a year 
before or the year immediately following, or in the same year as, the 
year of such control period.

certified for use under the Texas SO2 Trading Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by which the designated 
representative must submit the additional information required to 
complete the certification application. If the designated representative 
does not comply with the notice of incompleteness by the specified date, 
then the Administrator may issue a notice of disapproval under paragraph 
(d)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter).
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.932(b).

application reveal that any monitoring system should not have been 
certified or recertified because it did not meet a particular 
performance specification or other requirement under Sec. 97.931 or the 
applicable provisions of part 75 of this chapter, both at the time of 
the initial certification or recertification application submission and 
at the time of the audit, the Administrator will issue a notice of 
disapproval of the certification status of such monitoring system. For 
the purposes of this paragraph, an audit shall be either a field audit 
or an audit of any information submitted to the Administrator or any 
State or permitting authority. By issuing the notice of disapproval, the 
Administrator revokes prospectively the certification status of the 
monitoring system. The data measured and recorded by the monitoring 
system shall not be considered valid quality-assured data from the date 
of issuance of the notification of the revoked certification status 
until the date and time that the owner or operator completes 
subsequently approved initial certification or recertification tests for 
the monitoring system. The owner or operator shall follow the applicable 
initial certification or recertification procedures in Sec. 97.931 for 
each disapproved monitoring system.

    (2) The emissions and heat input data determined in accordance with 
Sec. Sec. 97.1030 through 97.1035 shall be used to calculate 
allocations of CSAPR NOX Ozone Season Group 3 allowances 
under Sec. Sec. 97.1011 and 97.1012 and to determine compliance with 
the CSAPR NOX Ozone Season Group 3 primary and secondary 
emissions limitations and assurance provisions under paragraph (c) of 
this section, provided that, for each monitoring location from which 
mass emissions are reported, the mass emissions amount used in 
calculating such allocations and determining such compliance shall be 
the mass emissions amount for the monitoring location determined in 
accordance with Sec. Sec. 97.1030 through 97.1035 and rounded to the 
nearest ton, with any fraction of a ton less than 0.50 being deemed to 
be zero.
    (c) * * *
    (1) CSAPR NOX Ozone Season Group 3 primary and secondary emissions 
limitations--(i) Primary emissions limitation. As of the allowance 
transfer deadline for a control period in a given year, the owners and 
operators of each CSAPR NOX Ozone Season Group 3 source and 
each CSAPR NOX Ozone Season Group 3 unit at the source shall 
hold, in the source's compliance account, CSAPR NOX Ozone 
Season Group 3 allowances available for deduction for such control 
period under Sec. 97.1024(a) in an amount not less than the amount 
determined under Sec. 97.1024(b), comprising the sum of--
    (A) The tons of total NOX emissions for such control 
period from all CSAPR NOX Ozone Season Group 3 units at the 
source; plus
    (B) Two times the excess, if any, over 50 tons of the sum, for all 
CSAPR NOX Ozone Season Group 3 units at the source and all 
calendar days of the control period, of any NOX emissions 
from such a unit on any calendar day of the control period exceeding the 
NOX emissions that would have occurred on that calendar day 
if the unit had combusted the same daily heat input and emitted at any 
backstop daily NOX emissions rate applicable to the unit for 
that control period.
    (ii) Exceedances of primary emissions limitation. If total 
NOX emissions during a control period in a given year from 
the CSAPR NOX Ozone Season Group 3 units at a CSAPR 
NOX Ozone Season Group 3 source are in excess of the CSAPR 
NOX Ozone Season Group 3 primary emissions limitation set 
forth in paragraph (c)(1)(i) of this section, then:

                                * * * * *

    (iii) Secondary emissions limitation. The owner or operator of a 
CSAPR NOX Ozone Season Group 3 unit subject to an emissions 
limitation under Sec. 97.1025(c)(1) shall not discharge, or allow to be 
discharged, emissions of NOX to the atmosphere during a 
control period in excess of the tonnage amount calculated in accordance 
with Sec. 97.1025(c)(2).
    (iv) Exceedances of secondary emissions limitation. If total 
NOX emissions during a control period in a given year from a 
CSAPR NOX Ozone Season Group 3 unit are in excess of the 
amount of a CSAPR NOX Ozone Season Group 3 secondary 
emissions limitation applicable to the unit for the control period under 
paragraph (c)(1)(iii) of this section, then the owners and operators of 
the unit and the source at which the unit is located shall pay any fine, 
penalty, or assessment or comply with any other remedy imposed, for the 
same violations, under the Clean Air Act, and each ton of such excess 
emissions and each day of such control period shall constitute a 
separate violation of this subpart and the Clean Air Act.
    (2) * * *
    (iii) Total NOX emissions from all CSAPR NOX 
Ozone Season Group 3 units at CSAPR NOX Ozone Season Group 3 
sources in a State (and Indian country within the borders of such State) 
during a control period in a given year exceed the State assurance level 
if such total NOX emissions exceed the sum, for such control 
period, of the State NOX Ozone Season Group 3 trading budget 
under Sec. 97.1010(a) and the State's variability limit under Sec. 
97.1010(e).

                                * * * * *

    (3) Compliance periods. (i) A CSAPR NOX Ozone Season 
Group 3 unit shall be subject to the requirements under paragraphs 
(c)(1)(i) and (ii) and (c)(2) of this section for the control period

    (ii) If the preset trading budget indicated for a given State and 
control period in table 2 to paragraph (a)(2)(i) of this section is less 
than the dynamic trading budget for the State and control period 
referenced in the applicable notice promulgated under paragraph 
(a)(4)(v)(C) of this section, then the State NOX Ozone Season 
Group 3 trading budget for the State and control period shall be the 
dynamic trading budget for the State and control period referenced in 
the applicable notice promulgated under paragraph (a)(4)(v)(C) of this 
section.
    (3) The State NOX Ozone Season Group 3 trading budget for 
each State and each control period in 2030 and thereafter shall be the 
dynamic trading budget for the State and control period referenced in 
the applicable notice promulgated under paragraph (a)(4)(v)(C) of this 
section.
    (4) The Administrator will calculate the dynamic trading budget for 
each State and each control period in 2026 and thereafter in the year 
before the year of the control period as follows:
    (i) The Administrator will include a unit in a State (and Indian 
country within the borders of the State) in the calculation of the 
State's dynamic trading budget for a control period if--
    (A) To the best of the Administrator's knowledge, the unit qualifies 
as a CSAPR NOX Ozone Season Group 3 unit under Sec. 97.1004, 
without regard to whether the unit has permanently retired, provided 
that including a unit in the calculation of a dynamic trading budget 
does not constitute a determination that the unit is a CSAPR 
NOX Ozone Season Group 3 unit, and not including a unit in 
the calculation of a dynamic trading budget does not constitute a 
determination that the unit is not a CSAPR NOX Ozone Season 
Group 3 unit;
    (B) The unit's deadline for certification of monitoring systems 
under Sec. 97.1030(b) is on or before May 1 of the year two years 
before the year of the control period for which the dynamic trading 
budget is being calculated; and
    (C) The owner or operator reported heat input greater than zero for 
the unit in accordance with part 75 of this chapter for the historical 
control period in the year two years before the year of the control 
period for which the dynamic trading budget is being calculated.
    (ii) For each unit identified for inclusion in the calculation of 
the State's dynamic trading budget for a control period under paragraph 
(a)(4)(i) of this section, the Administrator will calculate the heat 
input amount in mmBtu to be used in the budget calculation as follows:
    (A) For each such unit, the Administrator will determine the 
following unit-level amounts:
    (1) The total heat input amounts reported in accordance with part 75 
of this chapter for the unit for the historical control periods in the 
years two, three, four, five, and six years before the year of the 
control period for which the dynamic trading budget is being calculated, 
except any historical control period that commenced before the unit's 
first deadline under any regulatory program to begin recording and 
reporting heat input in accordance with part 75 of this chapter; and
    (2) The average of the three highest unit-level total heat input 
amounts identified for the unit under paragraph (a)(4)(iv)(A)(1) of this 
section or, if fewer than three non-zero amounts are identified for the 
unit, the average of all such non-zero total heat input amounts.
    (B) For the State, the Administrator will determine the following 
state-level amounts:
    (1) The sum for all units in the State meeting the criterion under 
paragraph (a)(4)(i)(A) of this section, without regard to whether such 
units also meet the criteria under paragraphs (a)(4)(i)(B) and (C) of 
this section, of the total heat input amounts reported in accordance 
with part 75 of this chapter for the historical control periods in the 
years two, three, and four years before the year of the control period 
for which the dynamic trading budget is being calculated, provided that 
for the historical control periods in 2022 and 2023, the total reported 
heat input amounts for Nevada and Utah as otherwise determined under 
this paragraph (a)(4)(ii)(B)(1) shall be increased by 13,489,332 mmBtu 
for Nevada and by 1,888,174 mmBtu for Utah;

[[Page 507]]

    (2) The average of the three state-level total heat input amounts 
calculated for the State under paragraph (a)(4)(ii)(B)(1) of this 
section; and
    (3) The sum for all units identified for inclusion in the 
calculation of the State's dynamic trading budget for the control period 
under paragraph (a)(4)(i) of this section of the unit-level average heat 
input amounts calculated under paragraph (a)(4)(ii)(A)(2) of this 
section.
    (C) The heat input amount for a unit used in the calculation of the 
State's dynamic trading budget shall be the product of the unit-level 
average total heat input amount calculated for the unit under paragraph 
(a)(4)(ii)(A)(2) of this section multiplied by a fraction whose 
numerator is the state-level average total heat input amount calculated 
under paragraph (a)(4)(ii)(B)(2) of this section and whose denominator 
is the state-level sum of the unit-level average heat input amounts 
calculated under paragraph (a)(4)(ii)(B)(3) of this section.
    (iii) For each unit identified for inclusion in the calculation of 
the State's dynamic trading budget for a control period under paragraph 
(a)(4)(i) of this section, the Administrator will identify the 
NOX emissions rate in lb/mmBtu to be used in the calculation 
as follows:
    (A) For a unit listed in the document entitled ``Unit-Specific Ozone 
Season NOX Emissions Rates for Dynamic Budget Calculations'' 
posted at www.regulations.gov in docket EPA-HQ-OAR-2021-0668, the 
NOX emissions rate used in the calculation for the control 
period shall be the NOX emissions rate shown for the unit and 
control period in that document.
    (B) For a unit not listed in the document referenced in paragraph 
(a)(4)(iii)(A) of this section, the NOX emissions rate used 
in the calculation for the control period shall be identified according 
to the type of unit and the type of fuel combusted by the unit during 
the control period beginning May 1 on or immediately after the unit's 
deadline for certification of monitoring systems under Sec. 97.1030(b) 
as follows:
    (1) 0.011 lb/mmBtu, for a simple cycle combustion turbine or a 
combined cycle combustion turbine other than an integrated coal 
gasification combined cycle unit;
    (2) 0.030 lb/mmBtu, for a boiler combusting only fuel oil or gaseous 
fuel (other than coal-derived fuel) during such control period; or
    (3) 0.050 lb/mmBtu, for a boiler combusting any amount of coal or 
coal-derived fuel during such control period or any other unit not 
covered by paragraph (a)(4)(iii)(B)(1) or (2) of this section.
    (iv) The Administrator will calculate the State's dynamic trading 
budget for the control period as the sum (converted to tons at a 
conversion factor of 2,000 lb/ton and rounded to the nearest ton), for 
all units identified for inclusion in the calculation under paragraph 
(a)(4)(i) of this section, of the product for each such unit of the heat 
input amount in mmBtu calculated for the unit under paragraph (a)(4)(ii) 
of this section multiplied by the NOX emissions rate in lb/
mmBtu identified for the unit under paragraph (a)(4)(iii) of this 
section.
    (v)(A) By March 1, 2025 and March 1 of each year thereafter, the 
Administrator will calculate the dynamic trading budget for each State, 
in accordance with paragraphs (a)(4)(i) through (iv) of this section and 
Sec. Sec. 97.1006(b)(2) and 97.1030 through 97.1035, for the control 
period in the year after the year of the applicable calculation deadline 
under this paragraph (a)(4)(v)(A) and will promulgate a notice of data 
availability of the results of the calculations.
    (B) For each notice of data availability required in paragraph 
(a)(4)(v)(A) of this section, the Administrator will provide an 
opportunity for submission of objections to the calculations referenced 
in such notice. Objections shall be submitted by the deadline specified 
in such notice and shall be limited to addressing whether the 
calculations (including the identification of the units included in the 
calculations) are in accordance with the provisions referenced in 
paragraph (a)(4)(v)(A) of this section.
    (C) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (a)(4)(v)(A) of this section. By May 1 
immediately after the promulgation of each notice of data availability 
required in paragraph (a)(4)(v)(A) of this section, the Administrator 
will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (a)(4)(v)(B) of 
this section.
    (b) Indian country existing unit set-asides for the control periods 
in 2023 and thereafter. The Indian country existing unit set-aside for 
allocations of CSAPR NOX Ozone Season Group 3 allowances for 
each State for each control period in 2023 and thereafter shall be 
calculated as the sum of all allowance allocations to units in areas of 
Indian country within the borders of the State not subject to the 
State's SIP authority as provided in the applicable notice of data 
availability for the control period referenced in Sec. 97.1011(a)(2).
    (c) New unit set-asides. (1) The new unit set-asides for allocations 
of CSAPR NOX Ozone Season Group 3 allowances for the control 
periods in 2021 and 2022 for each State with CSAPR NOX Ozone 
Season Group 3 trading budgets for such control periods shall be as

    (ii) For a control period in 2026 through 2029 if the State 
NOX Ozone Season Group 3 trading budget for the State and 
control period under paragraph (a)(2) of this section is the dynamic 
trading budget for the State and control period referenced in the 
applicable notice promulgated under paragraph (a)(4)(v)(C) of this 
section, and for a control period in 2030 and thereafter, the state-
level total heat input amount shall be the amount for the State and 
control period calculated under paragraph (a)(4)(ii)(B)(2) of this 
section.
    (f) Relationship of trading budgets, set-asides, and variability 
limits. Each State NOX Ozone Season Group 3 trading budget in 
this section includes any tons in an Indian country existing unit set-
aside, a new unit set-aside, or an Indian country new unit set-aside but 
does not include any tons in a variability limit.



Sec. 97.1011  Timing requirements for CSAPR NOX Ozone Season Group 3 allowance allocations.

    (a) Existing units. (1) CSAPR NOX Ozone Season Group 3 
allowances are allocated, for the control periods in 2021 and each year 
thereafter, as provided in a notice of data availability issued by the 
Administrator. Providing an allocation to a unit in such notice does not 
constitute a determination that the unit is a CSAPR NOX Ozone 
Season Group 3 unit, and not providing an allocation to a unit in such 
notice does not constitute a determination that the unit is not a CSAPR 
NOX Ozone Season Group 3 unit. For the control period in 
2021, a unit's allocation under this paragraph will include the unit's 
share (if any) of the supplemental amount of CSAPR NOX Ozone 
Season Group 3 allowances determined for the State in which the unit is 
located under Sec. 97.1010(d).
    (2) Notwithstanding paragraph (a)(1) of this section, if a unit 
provided an allocation in the notice of data availability issued under 
paragraph (a)(1) of this section does not operate, starting after 2020, 
during the control period in two consecutive years, such unit will not 
be allocated the CSAPR NOX Ozone Season Group 3 allowances 
provided in such notice for the unit for the control periods in the 
fifth year after the first such year and in each year after that fifth 
year. All CSAPR NOX Ozone Season Group 3 allowances that 
would otherwise have been allocated to such unit will be allocated to 
the new unit set-aside for the State where such unit is located and for 
the respective years involved. If such unit resumes operation, the 
Administrator will allocate CSAPR NOX Ozone Season Group 3 
allowances to the unit in accordance with paragraph (b) of this section.
    (b) New units--(1) New unit set-asides. (i) By March 1, 2022 and 
March 1 of each year thereafter, the Administrator will calculate the 
CSAPR NOX Ozone Season Group 3 allowance allocation to each 
CSAPR NOX Ozone Season Group 3 unit in a State, in accordance 
with Sec. 97.1012(a)(2) through (7), (10), and (12) and Sec. Sec. 
97.1006(b)(2) and 97.1030 through 97.1035, for the control period in the 
year before the year of the applicable calculation deadline under this 
paragraph and will promulgate a notice of data availability of the 
results of the calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(1)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each 
notice of data availability required in paragraph (b)(1)(i) of this 
section and shall be limited to addressing whether the calculations 
(including the identification of the CSAPR NOX Ozone Season 
Group 3 units) are in accordance with the provisions referenced in 
paragraph (b)(1)(i) of this section.
    (B) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(1)(i) of this section. By May 1 immediately 
after the promulgation of each notice of data availability required in 
paragraph (b)(1)(i) of this section, the Administrator will promulgate a 
notice of data availability of the results of the calculations 
incorporating any adjustments that the Administrator determines to be 
necessary and the reasons for accepting or rejecting any objections 
submitted in accordance with paragraph (b)(1)(ii)(A) of this section.
    (iii) [Reserved]
    (iv) [Reserved]
    (v) To the extent any CSAPR NOX Ozone Season Group 3 
allowances are

[[Page 511]]

added to the new unit set-aside after promulgation of each notice of 
data availability required in paragraph (b)(1)(ii) of this section, the 
Administrator will promulgate additional notices of data availability, 
as deemed appropriate, of the allocation of such CSAPR NOX 
Ozone Season Group 3 allowances in accordance with Sec. 97.1012(a)(10).
    (2) Indian country new unit set-asides. (i) By March 1, 2022 and 
March 1 of each year thereafter, the Administrator will calculate the 
CSAPR NOX Ozone Season Group 3 allowance allocation to each 
CSAPR NOX Ozone Season Group 3 unit in Indian country within 
the borders of a State, in accordance with Sec. 97.1012(b)(2) through 
(7), (10), and (12) and Sec. Sec. 97.1006(b)(2) and 97.1030 through 
97.1035, for the control period in the year before the year of the 
applicable calculation deadline under this paragraph and will promulgate 
a notice of data availability of the results of the calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(2)(i) of this section, the Administrator will provide an opportunity 
for submission of objections to the calculations referenced in such 
notice.
    (A) Objections shall be submitted by the deadline specified in each

    (c) Units incorrectly allocated CSAPR NOX Ozone Season Group 3 
allowances. (1) For each control period in 2021 and thereafter, if the 
Administrator determines that CSAPR NOX Ozone Season Group 3 
allowances were allocated under paragraph (a) of this section, or under 
a provision of a SIP revision approved under Sec. 52.38(b)(10), (11), 
or (12) of this chapter, where such control period and the recipient are 
covered by the provisions of paragraph (c)(1)(i) of this section or were 
allocated under Sec. 97.1012(a)(2) through (7) and (12) and (b)(2) 
through (7) and (12), or under a provision of a SIP revision approved 
under Sec. 52.38(b)(11) or (12) of this chapter, where such control 
period and the recipient are covered by the provisions of paragraph 
(c)(1)(ii) of this section, then the Administrator will notify the 
designated representative of the recipient and will act in accordance 
with the procedures set forth in paragraphs (c)(2) through (5) of this 
section:
    (i)(A) The recipient is not actually a CSAPR NOX Ozone 
Season Group 3 unit under Sec. 97.1004 as of May 1, 2021 and is 
allocated CSAPR NOX Ozone Season Group 3 allowances for such 
control period or, in the case of an allocation under a provision of a

allowances allocated under paragraph (a) of this section, or under a 
provision of a SIP revision approved under Sec. 52.38(b)(10), (11), or 
(12) of this chapter, were allocated for such control period.
    (ii) The recipient is not actually a CSAPR NOX Ozone 
Season Group 3 unit under Sec. 97.1004 as of May 1 of such control 
period and is allocated CSAPR NOX Ozone Season Group 3 
allowances for such control period or, in the case of an allocation 
under a provision of a SIP revision approved under Sec. 52.38(b)(11) or 
(12) of this chapter, the recipient is not actually a CSAPR 
NOX Ozone Season Group 3 unit as of May 1 of such control 
period and is allocated CSAPR NOX Ozone Season Group 3 
allowances for such control period that the SIP revision provides should 
be allocated only to recipients that are CSAPR NOX Ozone 
Season Group 3 units as of May 1 of such control period.
    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such CSAPR NOX Ozone Season 
Group 3 allowances under Sec. 97.1021.

Ozone Season Group 3 allowances under Sec. 97.1021 and if the 
Administrator makes the determination under paragraph (c)(1) of this 
section before making deductions for the source that includes such 
recipient under Sec. 97.1024(b) for such control period, then the 
Administrator will deduct from the account in which such CSAPR 
NOX Ozone Season Group 3 allowances were recorded an amount 
of CSAPR NOX Ozone Season Group 3 allowances allocated for 
the same or a prior control period equal to the amount of such already 
recorded CSAPR NOX Ozone Season Group 3 allowances. The 
authorized account representative shall ensure that there are sufficient 
CSAPR NOX Ozone Season Group 3 allowances in such account for 
completion of the deduction.
    (4) If the Administrator already recorded such CSAPR NOX

    Effective Date Note: At 88 FR 36910, June 5, 2023, Sec. 97.1011 was 
amended by revising the section heading and paragraphs (a), (b), 
paragraph (c) heading, and paragraphs (c)(1) and (5), effective Aug. 4, 
2023. For the convenience of the user, the revised text is set forth as 
follows:



Sec. 97.1011  CSAPR NOX Ozone Season Group 3 allowance allocations to 
          existing units.

    (a) Allocations to existing units in general. (1) For the control 
periods in 2021 and each year thereafter, CSAPR NOX Ozone 
Season Group 3 allowances will be allocated to units in each State and 
areas of Indian country within the borders of the State subject to the 
State's SIP authority as provided in notices of data availability issued 
by the Administrator. Starting with the control period in 2026, the 
notices of data availability will be the notices issued under paragraph 
(b)(11)(iii) of this section.
    (2) For the control periods in 2023 and each year thereafter, CSAPR 
NOX Ozone Season Group 3 allowances will be allocated to 
units in areas of Indian country within the borders of each State not 
subject to the State's SIP authority as provided in notices of data 
availability issued by the Administrator. Starting with the control 
period in 2026, the notices of data availability will be the notices 
issued under paragraph (b)(11)(iii) of this section.
    (3) Providing an allocation to a unit in a notice of data 
availability does not constitute a determination that the unit is a 
CSAPR NOX Ozone Season Group 3 unit, and not providing an 
allocation to a unit in such notice does not constitute a determination 
that the unit is not a CSAPR NOX Ozone Season Group 3 unit.
    (b) Calculation of default allocations to existing units for control 
periods in 2026 and thereafter. For each control period in 2026 and 
thereafter, and for the CSAPR NOX Ozone Season Group 3 units 
in each State and areas of Indian country within the borders of the 
State, the Administrator will calculate default allocations of CSAPR 
NOX Ozone Season Group 3 allowances to the CSAPR 
NOX Ozone Season Group 3 units as follows:
    (1) For each State and control period, the total amount of CSAPR 
NOX Ozone Season Group 3 allowances for which the 
Administrator will calculate default allocations shall be the remainder 
of the State NOX Ozone Season Group 3 trading budget for the 
control period under Sec. 97.1010(a) minus the new unit set-aside for 
the control period under Sec. 97.1010(c).
    (2) The Administrator will calculate a default allocation of CSAPR 
NOX Ozone Season Group 3 allowances for each CSAPR 
NOX Ozone Season Group 3 unit in the State and Indian country 
within the borders of the State meeting the following criteria:
    (i) To the best of the Administrator's knowledge, the unit qualifies 
as a CSAPR NOX Ozone Season Group 3 unit under Sec. 97.1004, 
without regard to whether the unit has permanently retired;
    (ii) The unit's deadline for certification of monitoring systems 
under Sec. 97.1030(b) is on or before May 1 of the year two years 
before the year of the control period for which the allowances are being 
allocated; and
    (iii) The owner or operator reported heat input greater than zero 
for the unit in accordance with part 75 of this chapter for the 
historical control period in the year two years before the year of the 
control period for which the allowances are being allocated.
    (3) For each CSAPR NOX Ozone Season Group 3 unit for 
which a default allocation is being calculated for a control period, the 
Administrator will calculate an average heat input amount to be used in 
the allocation calculations as follows:
    (i) The Administrator will identify the total heat input amounts 
reported for the unit in accordance with part 75 of this chapter for the 
historical control periods in the years two, three, four, five, and six 
years before the year of the control period for which the allowances are 
being allocated, except any historical control period that commenced 
before the unit's first deadline under any regulatory program to begin 
recording and reporting heat input in accordance with part 75 of this 
chapter.
    (ii) The average heat input amount used in the allocation 
calculations shall be the average of the three highest total heat input 
amounts identified for the unit under paragraph (b)(3)(i) of this 
section or, if fewer than three non-zero amounts are identified for the 
unit, the average of all such non-zero total heat input amounts.
    (4) For each CSAPR NOX Ozone Season Group 3 unit for 
which a default allocation is being calculated for a control period, the 
Administrator will calculate a tentative maximum allocation amount to be 
used in the allocation calculations as follows:
    (i) The Administrator will identify the total NOX 
emissions amounts reported for the unit in accordance with part 75 of 
this chapter for the historical control periods in the years two, three, 
four, five, and six years

[[Page 514]]

before the year of the control period for which the allowances are being 
allocated.
    (ii) The tentative maximum allocation amount used in the allocation 
calculations shall be the highest of the total NOX emissions 
amounts identified for the unit under paragraph (b)(4)(i) of this 
section or, if less, any applicable amount calculated under paragraph 
(b)(4)(iii) of this section.
    (iii)(A) The tentative maximum allocation amount under paragraph 
(b)(4)(ii) of this section for a unit described in paragraph 
(b)(4)(iii)(B) or (C) of this section may not exceed a maximum 
controlled baseline calculated as the product (converted to tons at a 
conversion factor of 2,000 lb/ton and rounded to the nearest ton) of the 
highest total heat input amount identified for the unit under paragraph 
(b)(3)(i) of this section in mmBtu multiplied by a NOX 
emissions rate of 0.08 lb/mmBtu.
    (B) For the control period in 2026, a maximum controlled baseline 
under paragraph (b)(4)(iii)(A) of this section shall apply to any unit 
that combusted any coal or solid coal-derived fuel during the historical 
control period for which the unit's heat input was most recently 
reported, that serves a generator with nameplate capacity of 100 MW or 
more, and that is equipped with selective catalytic reduction controls, 
except a circulating fluidized bed boiler.
    (C) For each control period in 2027 and thereafter, a maximum 
controlled baseline under paragraph (b)(4)(iii)(A) of this section shall 
apply to any unit that combusted any coal or solid coal-derived fuel 
during the historical control period for which the unit's heat input was 
most recently reported and that serves a generator with nameplate 
capacity of 100 MW or more, except a circulating fluidized bed boiler.
    (5) The Administrator will calculate the initial unrounded default 
allocations for each CSAPR NOX Ozone Season Group 3 unit 
according to the procedure in paragraph (b)(6) of this section and will 
recalculate the unrounded default allocations according to the 
procedures in paragraph (b)(7) or (8) of this section, as applicable, 
iterating the recalculations as necessary until the total of the 
unrounded default allocations to all eligible units equals the amount of 
allowances determined for the State under paragraph (b)(1) of this 
section.
    (6) The Administrator will calculate the initial unrounded default 
allocations to CSAPR NOX Ozone Season Group 3 units as 
follows:
    (i) The Administrator will calculate the sum, for all units 
determined under paragraph (b)(2) of this section to be eligible to 
receive default allocations, of the units' average heat input amounts 
determined under paragraph (b)(3)(ii) of this section.
    (ii) For each unit determined under paragraph (b)(2) of this section 
to be eligible to receive a default allocation, the Administrator will 
calculate the unit's unrounded default allocation as the lesser of--
    (A) The product of the total amount of allowances determined for the 
State and control period under paragraph (b)(1) of this section 
multiplied by a fraction whose numerator is the unit's average heat 
input amount determined under paragraph (b)(3)(ii) of this section and 
whose denominator is the sum determined under paragraph (b)(6)(i) of 
this section; and
    (B) The unit's tentative maximum allocation amount determined under 
paragraph (b)(4)(ii) of this section.
    (iii) If the sum of the unrounded default allocations determined 
under paragraph (b)(6)(ii) of this section is less than the total amount 
of allowances determined for the State and control period under 
paragraph (b)(1) of this section, the Administrator will follow the 
procedures in paragraph (b)(7) or (8) of this section, as applicable.
    (iv) If the sum of the unrounded default allocations determined 
under paragraph (b)(6)(ii) of this section equals the total amount of 
allowances determined for the State and control period under paragraph 
(b)(1) of this section, the Administrator will determine the rounded 
default allocations according to the procedures in paragraphs (b)(9) and 
(10) of this section.
    (7) If the unrounded default allocation determined in the previous 
round of the calculation procedure for at least one CSAPR NOX 
Ozone Season Group 3 unit is less than the unit's tentative maximum 
allocation amount determined under paragraph (b)(4)(ii) of this section, 
the Administrator will recalculate the unrounded default allocations as 
follows:
    (i) The Administrator will calculate the additional pool of 
allowances to be allocated as the remainder of the total amount of 
allowances determined for the State and control period under paragraph 
(b)(1) of this section minus the sum of the unrounded default 
allocations from the previous round of the calculation procedure for all 
units determined under paragraph (b)(2) of this section to be eligible 
to receive default allocations.
    (ii) The Administrator will calculate the sum, for all units whose 
unrounded default allocations determined in the previous round of the 
calculation procedure were less than the respective units' tentative 
maximum allocation amounts determined under paragraph (b)(4)(ii) of this 
section, of the units' average heat input amounts determined under 
paragraph (b)(3)(ii) of this section.
    (iii) For each unit whose unrounded default allocation determined in 
the previous round of the calculation procedure was less than the unit's 
tentative maximum allocation amount determined under paragraph 
(b)(4)(ii) of this section, the Administrator

[[Page 515]]

will recalculate the unit's unrounded default allocation as the lesser 
of--
    (A) The sum of the unit's unrounded default allocation determined in 
the previous round of the calculation procedure plus the product of the 
additional pool of allowances determined under paragraph (b)(7)(i) of 
this section multiplied by a fraction whose numerator is the unit's 
average heat input amount determined under paragraph (b)(3)(ii) of this 
section and whose denominator is the sum determined under paragraph 
(b)(7)(ii) of this section; and
    (B) The unit's tentative maximum allocation amount determined under 
paragraph (b)(4)(ii) of this section.
    (iv) Except as provided in paragraph (b)(7)(iii) of this section, a 
unit's unrounded default allocation shall equal the amount determined in 
the previous round of the calculation procedure.
    (v) If the sum of the unrounded default allocations determined under 
paragraphs (b)(7)(iii) and (iv) of this section is less than the total 
amount of allowances determined for the State and control period under 
paragraph (b)(1) of this section, the Administrator will iterate the 
procedures in paragraph (b)(7) of this section or follow the procedures 
in paragraph (b)(8) of this section, as applicable.
    (vi) If the sum of the unrounded default allocations determined 
under paragraphs (b)(7)(iii) and (iv) of this section equals the total 
amount of allowances determined for the State and control period under 
paragraph (b)(1) of this section, the Administrator will determine the 
rounded default allocations according to the procedures in paragraphs 
(b)(9) and (10) of this section.
    (8) If the unrounded default allocation determined in the previous 
round of the calculation procedure for every CSAPR NOX Ozone 
Season Group 3 unit equals the unit's tentative maximum allocation 
amount determined under paragraph (b)(4)(ii) of this section, the 
Administrator will recalculate the unrounded default allocations as 
follows:
    (i) The Administrator will calculate the additional pool of 
allowances to be allocated as the remainder of the total amount of 
allowances determined for the State and control period under paragraph 
(b)(1) of this section minus the sum of the unrounded default 
allocations from the previous round of the calculation procedure for all 
units determined under paragraph (b)(2) of this section to be eligible 
to receive default allocations.
    (ii) The Administrator will recalculate the unrounded default 
allocation for each eligible unit as the sum of--
    (A) The unit's unrounded default allocation as determined in the 
previous round of the calculation procedure; plus
    (B) The product of the additional pool of allowances determined 
under paragraph (b)(8)(i) of this section multiplied by a fraction whose 
numerator is the unit's average heat input amount determined under 
paragraph (b)(3)(ii) of this section and whose denominator is the sum 
determined under paragraph (b)(6)(i) of this section.
    (9) The Administrator will round the default allocation for each 
eligible unit determined under paragraph (b)(6), (7), or (8) of this 
section to the nearest allowance and make any adjustments required under 
paragraph (b)(10) of this section.
    (10) If the sum of the default allocations after rounding under 
paragraph (b)(9) of this section does not equal the total amount of 
allowances determined for the State and control period under paragraph 
(b)(1) of this section, the Administrator will adjust the default 
allocations as follows. The Administrator will list the CSAPR 
NOX Ozone Season Group 3 units in descending order based on 
such units' allocation amounts under paragraph (b)(9) of this section 
and, in cases of equal allocation amounts, in alphabetical order of the 
relevant sources' names and numerical order of the relevant units' 
identification numbers, and will adjust each unit's allocation amount 
upward or downward by one CSAPR NOX Ozone Season Group 3 
allowance (but not below zero) in the order in which the units are 
listed, and will repeat this adjustment process as necessary, until the 
total of the adjusted default allocations equals the total amount of 
allowances determined for the State and control period under paragraph 
(b)(1) of this section.
    (11)(i) By March 1, 2025 and March 1 of each year thereafter, the 
Administrator will calculate the default allocation of CSAPR 
NOX Ozone Season Group 3 allowances to each CSAPR 
NOX Ozone Season Group 3 unit in a State and Indian country 
within the borders of the State, in accordance with paragraphs (b)(1) 
through (10) of this section and Sec. Sec. 97.1006(b)(2) and 97.1030 
through 97.1035, for the control period in the year after the year of 
the applicable calculation deadline under this paragraph (b)(11)(i) and 
will promulgate a notice of data availability of the results of the 
calculations.
    (ii) For each notice of data availability required in paragraph 
(b)(11)(i) of this section, the Administrator will provide an 
opportunity for submission of objections to the calculations referenced 
in such notice. Objections shall be submitted by the deadline specified 
in such notice and shall be limited to addressing whether the 
calculations (including the identification of the CSAPR NOX 
Ozone Season Group 3 units) are in accordance with the provisions 
referenced in paragraph (b)(11)(i) of this section.
    (iii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(11)(i) of this section. By May 1 immediately 
after the

[[Page 516]]

promulgation of each notice of data availability required in paragraph 
(b)(11)(i) of this section, the Administrator will promulgate a notice 
of data availability of the results of the calculations incorporating 
any adjustments that the Administrator determines to be necessary and 
the reasons for accepting or rejecting any objections submitted in 
accordance with paragraph (b)(11)(ii) of this section.
    (c) Incorrect allocations of CSAPR NOX Ozone Season Group 3 
allowances to existing units. (1) For each control period in 2021 and 
thereafter, if the Administrator determines that CSAPR NOX 
Ozone Season Group 3 allowances were allocated for the control period to 
a recipient covered by the provisions of paragraph (c)(1)(i), (ii), or 
(iii) of this section, then the Administrator will notify the designated 
representative of the recipient and will act in accordance with the 
procedures set forth in paragraphs (c)(2) through (5) of this section:
    (i) The recipient is not actually a CSAPR NOX Ozone 
Season Group 3 unit under Sec. 97.1004 as of the first day of the 
control period and is allocated CSAPR NOX Ozone Season Group 
3 allowances for such control period under paragraph (a)(1) or (2) of 
this section;

Sec. 97.1012  CSAPR NOX Ozone Season Group 3 allowance allocations to new units.

    (a) Allocations from new unit set-asides. For each control period in 
2021 and thereafter and for the CSAPR NOX Ozone Season Group 
3 units in each State, the Administrator will allocate CSAPR 
NOX Ozone Season Group 3 allowances to the CSAPR 
NOX Ozone Season Group 3 units as follows:
    (1) The CSAPR NOX Ozone Season Group 3 allowances will be 
allocated to the following CSAPR NOX Ozone Season Group 3 
units, except as provided in paragraph (a)(10) of this section:
    (i) CSAPR NOX Ozone Season Group 3 units that are not 
allocated an amount of CSAPR NOX Ozone Season Group 3 
allowances in the notice of data availability issued under Sec. 
97.1011(a)(1) and that have deadlines for certification of monitoring 
systems under Sec. 97.1030(b) not later than September 30 of the year 
of the control period;
    (ii) CSAPR NOX Ozone Season Group 3 units whose 
allocation of an amount of CSAPR NOX Ozone Season Group 3

Administrator makes the determination under paragraph (c)(1) of this 
section before making deductions for the source that includes such

NOX Ozone Season Group 3 allowances were recorded an amount 
of CSAPR NOX Ozone Season Group 3 allowances allocated for 
the same or a prior control period equal to the amount of such already 
recorded CSAPR NOX Ozone Season Group 3 allowances. The 
authorized account representative shall ensure that there are sufficient 
CSAPR NOX Ozone Season Group 3 allowances in such account for 
completion of the deduction.

period in a prior year; and
    (2) Are held in the source's compliance account as of the allowance

deduction--(1) Identification by serial number. The designated

excess emissions for a control period in a given year in accordance with 
paragraph (b) or (d) of this section. In order to be complete, such 
request shall be submitted to the Administrator by the allowance 
transfer deadline for such control period and include, in a format 
prescribed by the Administrator, the identification of

[[Page 536]]

insufficient amount of CSAPR NOX Ozone Season Group 3 
allowances in such request, on a first-in, first-out accounting basis in

that were transferred to and recorded in the compliance account pursuant 
to this subpart or that were recorded in the compliance account pursuant 
to Sec. 97.526(d) or Sec. 97.826(d), in the order of recordation.
    (d) Deductions for excess emissions. After making the deductions for 
compliance under paragraph (b) of this section for a control period in a 
year in which the CSAPR NOX Ozone Season Group 3 source has 
excess emissions, the Administrator will deduct from the source's 
compliance account an amount of CSAPR NOX Ozone Season Group 
3 allowances, allocated or auctioned for a control period in a prior 
year or the control period in the year of the excess emissions or in the 
immediately following year, equal to two times the number of tons of the 
source's excess emissions.
    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account under 
paragraphs (b) and (d) of this section.

total NOX emissions exceed the State assurance level as 
described in Sec. 97.1006(c)(2)(iii); and
    (ii) For the set of any States (and Indian country within the 
borders of such States) for which the results of the calculations 
required in paragraph (b)(1)(i) of this section indicate that total 
NOX emissions exceed the respective State assurance levels 
for such control period--
    (A) Calculate, for each such State (and Indian country within the 
borders of such State) and such control period and each common 
designated representative for such control period for a group of one or 
more base CSAPR NOX Ozone Season Group 3 sources and units in 
such State (and such Indian country), the common designated 
representative's share of the total NOX emissions from all 
base CSAPR NOX Ozone Season Group 3 units at base CSAPR 
NOX Ozone Season Group 3 sources in such State (and such 
Indian country), the common designated representative's assurance level, 
and the amount (if any) of CSAPR NOX Ozone Season Group 3 
allowances that the owners and operators of such group of sources and 
units must hold in accordance with the calculation formula in Sec. 
97.1006(c)(2)(i); and
    (B) Promulgate a notice of data availability of the results of the 
calculations required in paragraphs (b)(1)(i) and (b)(1)(ii)(A) of this 
section, including separate calculations of the NOX emissions 
from each base CSAPR NOX Ozone Season Group 3 source in each 
such State (and Indian country within the borders of such State).
    (2) The Administrator will provide an opportunity for submission of 
objections to the calculations referenced by each notice of data 
availability required in paragraph (b)(1)(ii) of this section.
    (i) Objections shall be submitted by the deadline specified in such 
notice and shall be limited to addressing whether the calculations 
referenced in such notice are in accordance with Sec. 
97.1006(c)(2)(iii), Sec. Sec. 97.1006(b) and 97.1030 through 97.1035, 
the definitions of ``common designated representative'', ``common 
designated representative's assurance level'', and ``common designated 
representative's share'' in Sec. 97.1002, and the calculation formula 
in Sec. 97.1006(c)(2)(i).
    (ii) The Administrator will adjust the calculations to the extent 
necessary to ensure that they are in accordance with the provisions 
referenced in paragraph (b)(2)(i) of this section. By October 1 
immediately after the promulgation of such notice, the Administrator

[[Page 538]]

will promulgate a notice of data availability of the results of the 
calculations incorporating any adjustments that the Administrator 
determines to be necessary and the reasons for accepting or rejecting 
any objections submitted in accordance with paragraph (b)(2)(i) of this 
section.
    (3) For any State (and Indian country within the borders of such 
State) referenced in each notice of data availability required in 
paragraph (b)(2)(ii) of this section as having base CSAPR NOX 
Ozone Season Group 3 units with total NOX emissions exceeding 
the State assurance level for a control period in a given year, the 
Administrator will establish one assurance account for each set of 
owners and operators referenced, in the notice of data availability 
required under paragraph (b)(2)(ii) of this section, as all of the 
owners and operators of a group of base CSAPR NOX Ozone 
Season Group 3 sources and units in the State (and Indian country within 
the borders of such State) having a common designated representative for 
such control period and as being required to hold CSAPR NOX 
Ozone Season Group 3 allowances.
    (4)(i) As of midnight of November 1 immediately after the 
promulgation of each notice of data availability required in paragraph 
(b)(2)(ii) of this section, the owners and operators described in 
paragraph (b)(3) of this section shall hold in the assurance account 
established for them and for the appropriate base CSAPR NOX 
Ozone Season Group 3 sources, base CSAPR NOX Ozone Season 
Group 3 units, and State (and Indian country within the borders of such 
State) under paragraph (b)(3) of this section a total amount of CSAPR 
NOX Ozone Season Group 3 allowances, available for deduction 
under paragraph (a) of this section, equal to the amount such owners and 
operators are required to hold with regard to such sources, units and 
State (and Indian country within the borders of such State) as 
calculated by the Administrator and referenced in such notice.
    (ii) Notwithstanding the allowance-holding deadline specified in 
paragraph (b)(4)(i) of this section, if November 1 is not a business 
day, then such allowance-holding deadline shall be midnight of the first 
business day thereafter.
    (5) After November 1 (or the date described in paragraph (b)(4)(ii) 
of this section) immediately after the promulgation of each notice of 
data availability required in paragraph (b)(2)(ii) of this section and 
after the recordation, in accordance with Sec. 97.1023, of CSAPR 
NOX Ozone Season Group 3 allowance transfers submitted by 
midnight of such date, the Administrator will determine whether the 
owners and operators described in paragraph (b)(3) of this section hold, 
in the assurance account for the appropriate base CSAPR NOX 
Ozone Season Group 3 sources, base CSAPR NOX Ozone Season 
Group 3 units, and State (and Indian country within the borders of such 
State) established under paragraph (b)(3) of this section, the amount of 
CSAPR NOX Ozone Season Group 3 allowances available under 
paragraph (a) of this section that the owners and operators are required 
to hold with regard to such sources, units, and State (and Indian 
country within the borders of such State) as calculated by the 
Administrator and referenced in the notice required in paragraph 
(b)(2)(ii) of this section.
    (6) Notwithstanding any other provision of this subpart and any 
revision, made by or submitted to the Administrator after the 
promulgation of the notice of data availability required in paragraph 
(b)(2)(ii) of this section for a control period in a given year, of any 
data used in making the calculations referenced in such notice, the 
amounts of CSAPR NOX Ozone Season Group 3 allowances that the 
owners and operators are required to hold in accordance with Sec. 
97.1006(c)(2)(i) for such control period shall continue to be such 
amounts as calculated by the Administrator and referenced in such notice 
required in paragraph (b)(2)(ii) of this section, except as follows:
    (i) If any such data are revised by the Administrator as a result of 
a decision in or settlement of litigation concerning such data on appeal 
under part 78 of this chapter of such notice, or on appeal under section 
307 of the Clean Air Act of a decision rendered under part 78 of this 
chapter on appeal of such notice, then the Administrator

[[Page 539]]

will use the data as so revised to recalculate the amounts of CSAPR 
NOX Ozone Season Group 3 allowances that owners and operators 
are required to hold in accordance with the calculation formula in Sec. 
97.1006(c)(2)(i) for such control period with regard to the base CSAPR 
NOX Ozone Season Group 3 sources, base CSAPR NOX 
Ozone Season Group 3 units, and State (and Indian country within the 
borders of such State) involved, provided that such litigation under 
part 78 of this chapter, or the proceeding under part 78 of this chapter 
that resulted in the decision appealed in such litigation under section 
307 of the Clean Air Act, was initiated no later than 30 days after 
promulgation of such notice required in paragraph (b)(2)(ii) of this 
section.
    (ii) [Reserved]
    (iii) If the revised data are used to recalculate, in accordance 
with paragraph (b)(6)(i) of this section, the amount of CSAPR 
NOX Ozone Season Group 3 allowances that the owners and 
operators are required to hold for such control period with regard to 
the base CSAPR NOX Ozone Season Group 3 sources, base CSAPR 
NOX Ozone Season Group 3 units, and State (and Indian country 
within the borders of such State) involved--
    (A) Where the amount of CSAPR NOX Ozone Season Group 3 
allowances that the owners and operators are required to hold increases 
as a result of the use of all such revised data, the Administrator will 
establish a new, reasonable deadline on which the owners and operators 
shall hold the additional amount of CSAPR NOX Ozone Season 
Group 3 allowances in the assurance account established by the 
Administrator for the appropriate base CSAPR NOX Ozone Season 
Group 3 sources, base CSAPR NOX Ozone Season Group 3 units, 
and State (and Indian country within the borders of such State) under 
paragraph (b)(3) of this section. The owners' and operators' failure to 
hold such additional amount, as required, before the new deadline shall 
not be a violation of the Clean Air Act. The owners' and operators' 
failure to hold such additional amount, as required, as of the new 
deadline shall be a violation of the Clean Air Act. Each CSAPR 
NOX Ozone Season Group 3 allowance that the owners and 
operators fail to hold as required as of the new deadline, and each day 
in such control period, shall be a separate violation of the Clean Air 
Act.
    (B) For the owners and operators for which the amount of CSAPR 
NOX Ozone Season Group 3 allowances required to be held 
decreases as a result of the use of all such revised data, the 
Administrator will record, in all accounts from which CSAPR 
NOX Ozone Season Group 3 allowances were transferred by such 
owners and operators for such control period to the assurance account 
established by the Administrator for the appropriate base CSAPR 
NOX Ozone Season Group 3 sources, base CSAPR NOX 
Ozone Season Group 3 units, and State (and Indian country within the 
borders of such State) under paragraph (b)(3) of this section, a total 
amount of the CSAPR NOX Ozone Season Group 3 allowances held 
in such assurance account equal to the amount of the decrease. If CSAPR 
NOX Ozone Season Group 3 allowances were transferred to such 
assurance account from more than one account, the amount of CSAPR 
NOX Ozone Season Group 3 allowances recorded in each such 
transferor account will be in proportion to the percentage of the total 
amount of CSAPR NOX Ozone Season Group 3 allowances 
transferred to such assurance account for such control period from such 
transferor account.
    (C) Each CSAPR NOX Ozone Season Group 3 allowance held 
under paragraph (b)(6)(iii)(A) of this section as a result of 
recalculation of requirements under the CSAPR NOX Ozone 
Season Group 3 assurance provisions for such control period must be a 
CSAPR NOX Ozone Season Group 3 allowance allocated for a 
control period in a year before or the year immediately following, or in 
the same year as, the year of such control period.

Sec. 97.1025  Compliance with CSAPR NOX Ozone Season Group 3 assurance 
          provisions; CSAPR NOX Ozone Season Group 3 secondary emissions 
          limitation.

                                * * * * *

    (c) CSAPR NOX Ozone Season Group 3 secondary emissions limitation. 
(1) The owner or operator of a CSAPR NOX Ozone Season Group 3 
unit equipped with selective catalytic reduction controls or selective 
non-catalytic reduction controls shall not discharge, or allow to be 
discharged, emissions of NOX to the atmosphere during a 
control period in excess of the tonnage amount calculated in accordance 
with paragraph (c)(2) of this section, provided that the emissions 
limitation established under this paragraph (c)(1) shall apply to a unit 
for a control period only if:
    (i) The unit is included for the control period in a group of CSAPR 
NOX Ozone Season Group 3 units at CSAPR NOX Ozone 
Season Group 3 sources in a State (and Indian country within the borders 
of such State) having a common designated representative and the owners 
and operators of such units and sources are subject to a requirement for 
such control period to hold one or more CSAPR NOX Ozone 
Season Group 3 allowances under Sec. 97.1006(c)(2)(i) and paragraph (b) 
of this section with respect to such group; and
    (ii) The unit was required to report NOX emissions and 
heat input data for all or portions of at least 367 operating hours 
during the control period and all or portions of at least 367 operating 
hours during at least one historical control period under the CSAPR 
NOX Ozone Season Group 1 Trading Program, CSAPR 
NOX Ozone Season Group 2 Trading Program, or CSAPR 
NOX Ozone Season Group 3 Trading Program.
    (2) The amount of the emissions limitation applicable to a CSAPR 
NOX Ozone Season Group 3 unit for a control period under 
paragraph (c)(1) of this section, in tons of NOX, shall be 
calculated as the sum of 50 plus the product (converted to tons at a 
conversion factor of 2,000 lb/ton and rounded to the nearest ton) of 
multiplying--
    (i) The total heat input in mmBtu reported for the unit for the 
control period in accordance with Sec. Sec. 97.1030 through 97.1035; 
and
    (ii) A NOX emission rate of 0.10 lb/mmBtu or, if higher, 
the product of 1.25 times the lowest seasonal average NOX 
emission rate in lb/mmBtu achieved by the unit in any historical control 
period for which the unit was required to report NOX 
emissions and heat input data for all or portions of at least 367 
operating hours under the CSAPR NOX Ozone Season Group 1 
Trading Program, CSAPR NOX Ozone Season Group 2 Trading 
Program, or CSAPR NOX Ozone Season Group 3 Trading Program, 
where the unit's seasonal average NOX emission rate for each 
such historical control period shall be calculated from such reported 
data as the quotient (converted to lb/mmBtu at a conversion factor of 
2,000 lb/ton, and rounded to the nearest 0.0001 lb/mmBtu) of the unit's 
total NOX emissions in tons for the historical control period 
divided by the unit's total heat input in mmBtu for the historical 
control period.



Sec. 97.1026  Banking.

    (a) A CSAPR NOX Ozone Season Group 3 allowance may be 
banked for future use or transfer in a compliance account or a general 
account in accordance with paragraph (b) of this section.
    (b) Any CSAPR NOX Ozone Season Group 3 allowance that is 
held in a compliance account or a general account will remain in such

    (d) Before the allowance transfer deadline for each control period 
in 2024 and thereafter, the Administrator will deduct amounts of CSAPR 
NOX Ozone Season Group 3 allowances issued for the control 
periods in previous years exceeding the CSAPR NOX Ozone 
Season Group 3 allowance bank ceiling target for the control period in 
accordance with paragraphs (d)(1) through (4) of this section.
    (1) As soon as practicable on or after August 1, 2024, and August 1 
of each year thereafter, the Administrator will temporarily suspend 
acceptance of CSAPR NOX Ozone Season Group 3 allowance 
transfers submitted under Sec. 97.1022 and, before resuming acceptance 
of such transfers, will take the actions in paragraphs (d)(2) through 
(4) of this section.
    (2) The Administrator will determine each of the following values:
    (i) The total amount of CSAPR NOX Ozone Season Group 3 
allowances issued for control periods in years before the year of the 
deadline under paragraph (d)(1) of this section and held in all 
compliance and general accounts.
    (ii) The CSAPR NOX Ozone Season Group 3 allowance bank 
ceiling target for the control period in the year of the deadline under 
paragraph (d)(1) of this section, calculated as the product, rounded to 
the nearest allowance, of the sum for all States listed in Sec. 
52.38(b)(2)(iii) of this chapter of the State NOX Ozone 
Season Group 3 trading budgets under Sec. 97.1010(a) for such States 
for such control period multiplied by--
    (A) 0.210, for a control period in 2024 through 2029; or
    (B) 0.105, for a control period in 2030 and thereafter.
    (3) If the total amount of CSAPR NOX Ozone Season Group 3 
allowances determined under paragraph (d)(2)(i) of this section exceeds 
the CSAPR NOX Ozone Season Group 3 allowance bank ceiling 
target determined under paragraph (d)(2)(ii) of this section, then for 
each compliance account or general account holding CSAPR NOX 
Ozone Season Group 3 allowances issued for control periods in years 
before the year of the deadline under paragraph (d)(1) of this section, 
the Administrator will:
    (i) Determine the total amount of CSAPR NOX Ozone Season 
Group 3 allowances issued for control periods in years before the year 
of the deadline under paragraph (d)(1) of this section and held in the 
account.
    (ii) Determine the account's share of the CSAPR NOX Ozone 
Season Group 3 allowance bank ceiling target for the control period, 
calculated as the product, rounded up to the nearest allowance, of the 
CSAPR NOX Ozone Season Group 3 allowance bank ceiling target 
determined under paragraph (d)(2)(ii) of this section multiplied by a 
fraction whose numerator is the total amount of CSAPR NOX 
Ozone Season Group 3 allowances held in the account determined under 
paragraph (d)(3)(i) of this section and whose denominator is the total 
amount of CSAPR NOX Ozone Season Group 3 allowances held in 
all compliance and general accounts determined under paragraph (d)(2)(i) 
of this section.
    (iii) Deduct an amount of CSAPR NOX Ozone Season Group 3 
allowances issued for control periods in years before the year of the 
deadline under paragraph (d)(1) of this section equal to any positive 
remainder of the total amount of CSAPR NOX Ozone Season Group 
3 allowances held in the account determined under paragraph (d)(3)(i) of 
this section minus the account's share of the CSAPR NOX Ozone 
Season Group 3 allowance bank ceiling target for the control period 
determined under paragraph (d)(3)(ii) of this section. The allowances 
will be deducted on a first-in, first-out basis in the order set forth 
in Sec. 97.1024(c)(2)(i) and (ii).
    (iv) Record the deductions under paragraph (d)(3)(iii) of this 
section in the account.
    (4)(i) In computing any amounts of CSAPR NOX Ozone Season 
Group 3 allowances to be deducted from general accounts under paragraph 
(d)(3) of this section, the Administrator may group multiple general 
accounts whose ownership interests are held by the same or related 
persons or entities and treat the group of accounts as a single account 
for purposes of such computation.
    (ii) Following a computation for a group of general accounts in 
accordance with paragraph (d)(4)(i) of this section, the Administrator 
will deduct from and record in each individual account in such group a 
proportional share of the quantity of CSAPR NOX Ozone Season 
Group 3 allowances computed for such group, basing such shares on the 
respective quantities of CSAPR NOX Ozone Season Group 3 
allowances determined for such individual accounts under paragraph 
(d)(3)(i) of this section.
    (iii) In determining the proportional shares under paragraph 
(d)(4)(ii) of this section, the Administrator may employ any reasonable 
adjustment methodology to truncate or round each such share up or down 
to a whole number and to cause the total of such whole

[[Page 542]]

numbers to equal the amount of CSAPR NOX Ozone Season Group 3 
allowances computed for such group of accounts in accordance with 
paragraph (d)(4)(i) of this section, even where such adjustments cause 
the numbers of CSAPR NOX Ozone Season Group 3 allowances 
remaining in some individual accounts following the deductions to equal 
zero.



Sec. 97.1027  Account error.

    The Administrator may, at his or her sole discretion and on his or

through (iv) of this section and the procedures in Sec. 75.20(b)(5) and 
(g)(7) of this chapter (in lieu of the procedures in paragraph (d)(3)(v) 
of this section) apply, provided that in applying paragraphs (d)(3)(i) 
through (iv) of this section, the words ``certification'' and ``initial 
certification'' are replaced by the word ``recertification'' and the 
word ``certified'' is replaced by the word ``recertified''.
    (i) Notification of certification. The designated representative 
shall submit to the appropriate EPA Regional Office and the 
Administrator written notice of the dates of certification testing, in 
accordance with Sec. 97.1033.
    (ii) Certification application. The designated representative shall 
submit to the Administrator a certification application for each 
monitoring system. A complete certification application shall include 
the information specified in Sec. 75.63 of this chapter.
    (iii) Provisional certification date. The provisional certification 
date for a monitoring system shall be determined in accordance with 
Sec. 75.20(a)(3) of this chapter. A provisionally certified monitoring 
system may be used under the CSAPR NOX Ozone Season Group 3 
Trading Program for a period not to exceed 120 days after receipt by the 
Administrator of the complete certification application for the 
monitoring system under paragraph (d)(3)(ii) of this section. Data 
measured and recorded by the provisionally certified monitoring system, 
in accordance with the requirements of part 75 of this chapter, will be 
considered valid quality-assured data (retroactive to the date and time 
of provisional certification), provided that the Administrator does not 
invalidate the provisional certification by issuing a notice of 
disapproval within 120 days of the date of receipt of the complete 
certification application by the Administrator.
    (iv) Certification application approval process. The Administrator 
will issue a written notice of approval or disapproval of the 
certification application to the owner or operator within 120 days of 
receipt of the complete certification application under paragraph 
(d)(3)(ii) of this section. In the event the Administrator does not 
issue such a notice within such 120-day period, each monitoring system 
that meets the applicable performance requirements of part 75 of this 
chapter and is included in the certification application will be deemed 
certified for use under the CSAPR NOX Ozone Season Group 3 
Trading Program.
    (A) Approval notice. If the certification application is complete 
and shows that each monitoring system meets the applicable performance 
requirements of part 75 of this chapter, then the Administrator will 
issue a written notice of approval of the certification application 
within 120 days of receipt.
    (B) Incomplete application notice. If the certification application 
is not complete, then the Administrator will issue a written notice of 
incompleteness that sets a reasonable date by

[[Page 546]]

which the designated representative must submit the additional 
information required to complete the certification application. If the 
designated representative does not comply with the notice of 
incompleteness by the specified date, then the Administrator may issue a 
notice of disapproval under paragraph (d)(3)(iv)(C) of this section.
    (C) Disapproval notice. If the certification application shows that 
any monitoring system does not meet the performance requirements of part 
75 of this chapter or if the certification application is incomplete and 
the requirement for disapproval under paragraph (d)(3)(iv)(B) of this 
section is met, then the Administrator will issue a written notice of 
disapproval of the certification application. Upon issuance of such 
notice of disapproval, the provisional certification is invalidated by 
the Administrator and the data measured and recorded by each uncertified 
monitoring system shall not be considered valid quality-assured data 
beginning with the date and hour of provisional certification (as 
defined under Sec. 75.20(a)(3) of this chapter).
    (D) Audit decertification. The Administrator may issue a notice of 
disapproval of the certification status of a monitor in accordance with 
Sec. 97.1032(b).
    (v) Procedures for loss of certification. If the Administrator 
issues a notice of disapproval of a certification application under 
paragraph (d)(3)(iv)(C) of this section or a notice of disapproval of 
certification status under paragraph (d)(3)(iv)(D) of this section, 
then:
    (A) The owner or operator shall substitute the following values, for 
each disapproved monitoring system, for each hour of unit operation 
during the period of invalid data specified under Sec. 
75.20(a)(4)(iii), Sec. 75.20(g)(7), or Sec. 75.21(e) of this chapter 
and continuing until the applicable date and hour specified under Sec. 
75.20(a)(5)(i) or (g)(7) of this chapter:
    (1) For a disapproved NOX emission rate (i.e., 
NOX-diluent) system, the maximum potential NOX 
emission rate, as defined in Sec. 72.2 of this chapter.
    (2) For a disapproved NOX pollutant concentration monitor 
and disapproved flow monitor, respectively, the maximum potential

                       Subpart A_General Provision



Sec. 98.1  Purpose and scope.

    (a) This part establishes mandatory greenhouse gas (GHG) reporting 
requirements for owners and operators of certain facilities that 
directly emit GHG as well as for certain suppliers. For suppliers, the 
GHGs reported are the quantity that would be emitted from combustion or 
use of the products supplied.
    (b) Owners and operators of facilities and suppliers that are 
subject to this part must follow the requirements of this subpart and 
all applicable subparts of this part. If a conflict exists between a 
provision in subpart A and any other applicable subpart, the 
requirements of the applicable subpart shall take precedence.
    (c) For facilities required to report under onshore petroleum and 
natural gas production under subpart W of this part, the terms Owner and 
Operator used in subpart A have the same definition as Onshore petroleum 
and natural gas production owner or operator, as defined in Sec. 98.238 
of this part.

[74 FR 56374, Oct. 30, 2009, as amended at 75 FR 39758, July 12, 2010; 
76 FR 73898, Nov. 29, 2011; 76 FR 80573, Dec. 23, 2011]



Sec. 98.2  Who must report?

    (a) The GHG reporting requirements and related monitoring, 
recordkeeping, and reporting requirements of this part apply to the 
owners and operators of any facility that is located in the United 
States or under or attached to the Outer Continental Shelf (as defined 
in 43 U.S.C. 1331) and that meets the requirements of either paragraph 
(a)(1), (a)(2), or (a)(3) of this section; and any supplier that meets 
the requirements of paragraph (a)(4) of this section:
    (1) A facility that contains any source category that is listed in 
Table A-3 of this subpart. For these facilities, the annual GHG report 
must cover stationary fuel combustion sources (subpart C of this part), 
miscellaneous use of carbonates (subpart U of this part), and all 
applicable source categories listed in Tables A-3 and A-4 of this 
subpart.
    (2) A facility that contains any source category that is listed in 
Table A-4 of this subpart and that emits 25,000 metric tons 
CO2e or more per year in combined emissions from stationary 
fuel combustion units, miscellaneous uses of carbonate, and all 
applicable source categories that are listed in Table A-3 and Table A-4 
of this subpart. For these facilities, the annual GHG report must cover 
stationary fuel combustion sources (subpart C of this part), 
miscellaneous use of carbonates (subpart U of this part), and all 
applicable source categories listed in Table A-3 and Table A-4 of this 
subpart.
    (3) A facility that in any calendar year starting in 2010 meets all 
three of the conditions listed in this paragraph (a)(3). For these 
facilities, the annual GHG report must cover emissions from stationary 
fuel combustion sources only.
    (i) The facility does not meet the requirements of either paragraph 
(a)(1) or (a)(2) of this section.
    (ii) The aggregate maximum rated heat input capacity of the 
stationary fuel combustion units at the facility is 30 mmBtu/hr or 
greater.
    (iii) The facility emits 25,000 metric tons CO2e or more 
per year in combined emissions from all stationary fuel combustion 
sources.
    (4) A supplier that is listed in Table A-5 of this subpart. For 
these suppliers, the annual GHG report must cover all applicable 
products for which calculation methodologies are provided in the 
subparts listed in Table A-5 of this subpart.
    (5) Research and development activities are not considered to be 
part of any source category defined in this part.

[[Page 557]]

    (b) To calculate GHG emissions for comparison to the 25,000 metric 
ton CO2e per year emission threshold in paragraph (a)(2) of 
this section, the owner or operator shall calculate annual 
CO2e emissions, as described in paragraphs (b)(1) through 
(b)(4) of this section.
    (1) Calculate the annual emissions of CO2, 
CH4, N2O, and each fluorinated GHG in metric tons 
from all applicable source categories listed in paragraph (a)(2) of this 
section. The GHG emissions shall be calculated using the calculation 
methodologies specified in each applicable subpart and available company 
records.
    (2) For each general stationary fuel combustion unit, calculate the 
annual CO2 emissions in metric tons using any of the four 
calculation methodologies specified in Sec. 98.33(a). Calculate the 
annual CH4 and N2O emissions from the stationary 
fuel combustion sources in metric tons using the appropriate equation in 
Sec. 98.33(c). Exclude carbon dioxide emissions from the combustion of 
biomass, but include emissions of CH4 and N2O from 
biomass combustion.
    (3) For miscellaneous uses of carbonate, calculate the annual 
CO2 emissions in metric tons using the procedures specified 
in subpart U of this part.
    (4) Sum the emissions estimates from paragraphs (b)(1), (b)(2), and 
(b)(3) of this section for each GHG and calculate metric tons of 
CO2e using Equation A-1 of this section.
[GRAPHIC] [TIFF OMITTED] TR11DE14.000

Where:

CO2e = Carbon dioxide equivalent, metric tons/year.
GHGi = Mass emissions of each greenhouse gas, metric tons/
          year.
GWPi = Global warming potential for each greenhouse gas from 
          Table A-1 of this subpart.
n = The number of greenhouse gases emitted.

    (5) For purpose of determining if an emission threshold has been 
exceeded, include in the emissions calculation any CO2 that 
is captured for transfer off site.
    (c) To calculate GHG emissions for comparison to the 25,000 metric 
ton CO2e/year emission threshold for stationary fuel 
combustion under paragraph (a)(3) of this section, calculate 
CO2, CH4, and N2O emissions from each 
stationary fuel combustion unit by following the methods specified in 
paragraph (b)(2) of this section. Then, convert the emissions of each 
GHG to metric tons CO2e per year using Equation A-1 of this 
section, and sum the emissions for all units at the facility.
    (d) To calculate GHG quantities for comparison to the 25,000 metric 
ton CO2 per year threshold for importers and exporters of 
coal-to-liquid products under paragraph (a)(4) of this section, 
calculate the mass in metric tons per year of CO2 that would 
result from the complete combustion or oxidation of the quantity of 
coal-to-liquid products that are imported during the reporting year and, 
that are exported during the reporting year. Compare the imported 
quantities and the exported quantities separately to the 25,000 metric 
ton CO2 per year threshold. Calculate the quantities using 
the methodology specified in subpart LL of this part.
    (e) To calculate GHG quantities for comparison to the 25,000 metric 
ton CO2e per year threshold for importers and exporters of 
petroleum products under paragraph (a)(4) of this section, calculate the 
mass in metric tons per year of CO2 that would result from 
the complete combustion or oxidation of the combined volume of petroleum 
products and natural gas liquids that are imported during the reporting 
year and that are exported during the reporting year. Compare the 
imported quantities and the exported quantities separately to the 25,000 
metric ton CO2 per year threshold. Calculate the quantities 
using the methodology specified in subpart MM of this part.

[[Page 558]]

    (f) To calculate GHG quantities for comparison to the 25,000 metric 
ton CO2e per year threshold under paragraph (a)(4) of this 
section for importers and exporters of industrial greenhouse gases and 
for importers and exporters of CO2, the owner or operator 
shall calculate the mass in metric tons per year of CO2e 
imports and exports as described in paragraphs (f)(1) through (f)(3) of 
this section. Compare the imported quantities and the exported 
quantities separately to the 25,000 metric ton CO2 per year 
threshold.
    (1) Calculate the mass in metric tons per year of CO2, 
N2O, and each fluorinated GHG that is imported and the mass 
in metric tons per year of CO2, N2O, and each 
fluorinated GHG that is exported during the year.
    (2) Convert the mass of each imported and each GHG exported from 
paragraph (f)(1) of this section to metric tons of CO2e using 
Equation A-1 of this section.
    (3) Sum the total annual metric tons of CO2e in paragraph 
(f)(2) of this section for all imported GHGs. Sum the total annual 
metric tons of CO2e in paragraph (f)(2) of this section for 
all exported GHGs.
    (g) If a capacity or generation reporting threshold in paragraph 
(a)(1) of this section applies, the owner or operator shall review the 
appropriate records and perform any necessary calculations to determine 
whether the threshold has been exceeded.
    (h) An owner or operator of a facility or supplier that does not 
meet the applicability requirements of paragraph (a) of this section is 
not subject to this rule. Such owner or operator would become subject to 
the rule and reporting requirements, if a facility or supplier exceeds 
the applicability requirements of paragraph (a) of this section at a 
later time pursuant to Sec. 98.3(b)(3). Thus, the owner or operator 
should reevaluate the applicability to this part (including the revising 
of any relevant emissions calculations or other calculations) whenever 
there is any change that could cause a facility or supplier to meet the 
applicability requirements of paragraph (a) of this section. Such 
changes include but are not limited to process modifications, increases 
in operating hours, increases in production, changes in fuel or raw 
material use, addition of equipment, and facility expansion.
    (i) Except as provided in this paragraph, once a facility or 
supplier is subject to the requirements of this part, the owner or 
operator must continue for each year thereafter to comply with all 
requirements of this part, including the requirement to submit annual 
GHG reports, even if the facility or supplier does not meet the 
applicability requirements in paragraph (a) of this section in a future 
year.
    (1) If reported emissions are less than 25,000 metric tons 
CO2e per year for five consecutive years, then the owner or 
operator may discontinue complying with this part provided that the 
owner or operator submits a notification to the Administrator that 
announces the cessation of reporting and explains the reasons for the 
reduction in emissions. The notification shall be submitted no later 
than March 31 of the year immediately following the fifth consecutive 
year of emissions less than 25,000 tons CO2e per year. The 
owner or operator must maintain the corresponding records required under 
Sec. 98.3(g) for each of the five consecutive years prior to 
notification of discontinuation of reporting and retain such records for 
three years following the year that reporting was discontinued. The 
owner or operator must resume reporting if annual emissions in any 
future calendar year increase to 25,000 metric tons CO2e per 
year or more.
    (2) If reported emissions are less than 15,000 metric tons 
CO2e per year for three consecutive years, then the owner or 
operator may discontinue complying with this part provided that the 
owner or operator submits a notification to the Administrator that 
announces the cessation of reporting and explains the reasons for the 
reduction in emissions. The notification shall be submitted no later 
than March 31 of the year immediately following the third consecutive 
year of emissions less than 15,000 tons CO2e per year. The 
owner or operator must maintain the corresponding records required under 
Sec. 98.3(g) for each of the three consecutive years and retain such 
records for three years prior to notification of discontinuation of 
reporting following the

[[Page 559]]

year that reporting was discontinued. The owner or operator must resume 
reporting if annual emissions in any future calendar year increase to 
25,000 metric tons CO2e per year or more.
    (3) If the operations of a facility or supplier are changed such 
that all applicable processes and operations subject to paragraphs 
(a)(1) through (4) of this section cease to operate, then the owner or 
operator may discontinue complying with this part for the reporting 
years following the year in which cessation of such operations occurs, 
provided that the owner or operator submits a notification to the 
Administrator that announces the cessation of reporting and certifies to 
the closure of all applicable processes and operations no later than 
March 31 of the year following such changes. If one or more processes or 
operations subject to paragraphs (a)(1) through (4) of this section at a 
facility or supplier cease to operate, but not all applicable processes 
or operations cease to operate, then the owner or operator is exempt 
from reporting for any such processes or operations in the reporting 
years following the reporting year in which cessation of the process or 
operation occurs, provided that the owner or operator submits a 
notification to the Administrator that announces the cessation of 
reporting for the process or operation no later than March 31 following 
the first reporting year in which the process or operation has ceased 
for an entire reporting year. Cessation of operations in the context of 
underground coal mines includes, but is not limited to, abandoning and 
sealing the facility. This paragraph (i)(3) does not apply to seasonal 
or other temporary cessation of operations. This paragraph (i)(3) does 
not apply to the municipal solid waste landfills source category 
(subpart HH of this subpart), or the industrial waste landfills source 
category (subpart TT of this part). The owner or operator must resume 
reporting for any future calendar year during which any of the GHG-
emitting processes or operations resume operation.
    (4) The provisions of paragraphs (i)(1) and (2) of this section 
apply to suppliers subject to subparts LL through QQ of this part by 
substituting the term ``quantity of GHG supplied'' for ``emissions.'' 
For suppliers, the provisions of paragraphs (i)(1) and (2) apply 
individually to each importer and exporter and individually to each 
petroleum refinery, fractionator of natural gas liquids, local natural 
gas distribution company, and producer of CO2, 
N2O, or fluorinated greenhouse gases (e.g., a supplier of 
industrial greenhouse gases might qualify to discontinue reporting as an 
exporter of industrial greenhouse gases but still be required to report 
as an importer; or a company might qualify to discontinue reporting as a 
supplier of industrial greenhouse gases under subpart OO of this part 
but still be required to report as a supplier of carbon dioxide under 
subpart PP of this part).
    (5) If the operations of a facility or supplier are changed such 
that a process or operation no longer meets the ``Definition of Source 
Category'' as specified in an applicable subpart, then the owner or 
operator may discontinue complying with any such subpart for the 
reporting years following the year in which change occurs, provided that 
the owner or operator submits a notification to the Administrator that 
announces the cessation of reporting for the process or operation no 
later than March 31 following the first reporting year in which such 
changes persist for an entire reporting year. The owner or operator must 
resume complying with this part for the process or operation starting in 
any future calendar year during which the process or operation meets the 
``Definition of Source Category'' as specified in an applicable subpart.
    (6) If an entire facility or supplier is merged into another 
facility or supplier that is already reporting GHG data under this part, 
then the owner or operator may discontinue complying with this part for 
the facility or supplier, provided that the owner or operator submits a 
notification to the Administrator that announces the discontinuation of 
reporting and the e-GGRT identification number of the reconstituted 
facility no later than March 31 of the year following such changes.

1 and ending on December 31.
    (3) For any facility or supplier that becomes subject to this rule 
because of a physical or operational change that is made after January 
1, 2010, report emissions for the first calendar year in which the 
change occurs, beginning with the first month of the change and ending 
on December 31 of that year. For a facility or supplier that becomes 
subject to this rule solely because of an increase in hours of operation 
or level of production, the first month of the change is the month in 
which the increased hours of operation or level of production, if 
maintained for the remainder of the year, would cause the facility or 
supplier to exceed the applicable threshold. Each subsequent annual 
report must cover emissions for the calendar year, beginning on January 
1 and ending on December 31.
    (4) Unless otherwise stated, if the final day of any time period 
falls on a weekend or a federal holiday, the time period shall be 
extended to the next business day.
    (c) Content of the annual report. Except as provided in paragraph 
(d) of this section, each annual GHG report

[[Page 561]]

shall contain the following information:
    (1) Facility name or supplier name (as appropriate), and physical 
street address of the facility or supplier, including the city, State, 
and zip code. If the facility does not have a physical street address, 
then the facility must provide the latitude and longitude representing 
the geographic centroid or center point of facility operations in 
decimal degree format. This must be provided in a comma-delimited 
``latitude, longitude'' coordinate pair reported in decimal degrees to 
at least four digits to the right of the decimal point.
    (2) Year and months covered by the report.
    (3) Date of submittal.
    (4) For facilities, except as otherwise provided in paragraph 
(c)(12) of this section, report annual emissions of CO2,

Sec. 98.98) as follows.
    (i) Annual emissions (excluding biogenic CO2) aggregated 
for all GHG from all applicable source categories, expressed in metric 
tons of CO2e calculated using Equation A-1 of this subpart. 
For electronics manufacturing (as defined in Sec. 98.90), starting in 
reporting year 2012 the CO2e calculation must include each 
fluorinated heat transfer fluid (as defined in Sec. 98.98) whether or 
not it is also a fluorinated GHG.
    (ii) Annual emissions of biogenic CO2 aggregated for all 
applicable source categories, expressed in metric tons.

have a chemical-specific GWP in Table A-1 of this subpart, identify and 
report the fluorinated GHG group of which that fluorinated GHG is a 
member.
    (F) For electronics manufacturing (as defined in Sec. 98.90), each 
fluorinated heat transfer fluid (as defined in Sec. 98.98) that is not 
also a fluorinated GHG as specified under (c)(4)(iii)(E) of this 
section. If a fluorinated heat transfer fluid does not have a chemical-
specific GWP in Table A-1 of this subpart, identify and report the 
fluorinated GHG group of which that fluorinated heat transfer fluid is a 
member.
    (G) For each reported fluorinated GHG and fluorinated heat transfer 
fluid, report the following identifying information:

2015 (as part of the annual report for reporting year 2014), except as 
otherwise specified in Table A-7 of this subpart.
    (viii) Applicable source categories means stationary fuel combustion

[[Page 562]]

sources (subpart C of this part), miscellaneous use of carbonates 
(subpart U of this part), and all of the source categories listed in 
Table A-3 and Table A-4 of this subpart present at the facility.
    (5) For suppliers, report annual quantities of CO2, 
CH4, N2O, and each fluorinated GHG (as defined in 
Sec. 98.6) that would be emitted from combustion or use of the products 
supplied, imported, and exported during the year. Calculate and report 
quantities at the following levels:
    (i) Total quantity of GHG aggregated for all GHG from all applicable

for the facility or supplier. A facility or supplier that has two 
distinct products/activities/services providing comparable revenue may 
report a second primary NAICS code.
    (ii) Additional NAICS code(s). Report all additional NAICS codes 
that describe all product(s)/activity(s)/service(s) at the facility or 
supplier that are not related to the principal source of revenue.
    (11) Legal name(s) and physical address(es) of the highest-level 
United States parent company(s) of the owners (or operators) of the 
facility or supplier and the percentage of ownership interest for each 
listed parent company as of December 31 of the year for which data are 
being reported according to the following instructions:
    (i) If the facility or supplier is entirely owned by a single United 
States company that is not owned by another company, provide that 
company's legal name and physical address as the United States parent 
company and report 100 percent ownership.
    (ii) If the facility or supplier is entirely owned by a single 
United States company that is, itself, owned by another company (e.g., 
it is a division or subsidiary of a higher-level company), provide the 
legal name and physical address of the highest-level company in the 
ownership hierarchy as the United States parent company and report 100 
percent ownership.
    (iii) If the facility or supplier is owned by more than one United 
States company (e.g., company A owns 40 percent, company B owns 35 
percent, and company C owns 25 percent), provide

[[Page 563]]

the legal names and physical addresses of all the highest-level 
companies with an ownership interest as the United States parent 
companies, and report the percent ownership of each company.
    (iv) If the facility or supplier is owned by a joint venture or a

report ``U.S. Government'' and do not report physical address or percent 
ownership.
    (viii) The facility or supplier must refer to the reporting 
instructions of the electronic GHG reporting tool regarding standardized 
conventions for the naming of a parent company.
    (12) For the 2010 reporting year only, facilities that have ``part 
75 units'' (i.e. units that are subject to subpart D of this part or 
units that use the methods in part 75 of this chapter to quantify 
CO2 mass emissions in accordance with Sec. 98.33(a)(5)) must 
report annual GHG emissions either in full accordance with paragraphs 
(c)(4)(i) through (c)(4)(iii) of this section or in full accordance with 
paragraphs (c)(12)(i) through (c)(12)(iii) of this section. If the 
latter reporting option is chosen, you must report:
    (i) Annual emissions aggregated for all GHG from all applicable 
source categories, expressed in metric tons of CO2e 
calculated using Equation A-1 of this subpart. You must include biogenic 
CO2 emissions from part 75 units in these annual emissions, 
but exclude biogenic CO2 emissions from any non-part 75 units 
and other source categories.

    (E) Each fluorinated GHG (including those not listed in Table A-1 of 
this subpart).
    (13) An indication of whether the facility includes one or more 
plant sites that have been assigned a ``plant code'' (as defined under 
Sec. 98.6) by either the Department of Energy's Energy Information 
Administration or by the EPA's Clean Air Markets Division.
    (d) Special provisions for reporting year 2010. (1) Best available 
monitoring methods. During January 1, 2010 through March 31, 2010, 
owners or operators may use best available monitoring methods for any 
parameter (e.g., fuel use, daily carbon content of feedstock by process 
line) that cannot reasonably be measured according to the monitoring and 
QA/QC requirements of a relevant subpart. The owner or operator must use 
the calculation methodologies and equations in the ``Calculating GHG 
Emissions'' sections of each relevant subpart, but may use the best 
available monitoring method for any parameter for which it is not 
reasonably feasible to acquire, install, and operate a required piece of 
monitoring equipment by January 1, 2010. Starting no later than April 1, 
2010, the owner or operator must discontinue using best

[[Page 564]]

available methods and begin following all applicable monitoring and QA/
QC requirements of this part, except as provided in paragraphs (d)(2) 
and (d)(3) of this section. Best available monitoring methods means any 
of the following methods specified in this paragraph:
    (i) Monitoring methods currently used by the facility that do not 
meet the specifications of a relevant subpart.
    (ii) Supplier data.
    (iii) Engineering calculations.
    (iv) Other company records.
    (2) Requests for extension of the use of best available monitoring 
methods. The owner or operator may submit a request to the Administrator 
to use one or more best available monitoring methods beyond March 31, 
2010.
    (i) Timing of request. The extension request must be submitted to 
EPA no later than 30 days after the effective date of the GHG reporting 
rule.
    (ii) Content of request. Requests must contain the following 
information:
    (A) A list of specific item of monitoring instrumentation for which 
the request is being made and the locations where each piece of 
monitoring instrumentation will be installed.
    (B) Identification of the specific rule requirements (by rule 
subpart, section, and paragraph numbers) for which the instrumentation 
is needed.
    (C) A description of the reasons why the needed equipment could not 
be obtained and installed before April 1, 2010.
    (D) If the reason for the extension is that the equipment cannot be 
purchased and delivered by April 1, 2010, include supporting 
documentation such as the date the monitoring equipment was ordered, 
investigation of alternative suppliers and the dates by which 
alternative vendors promised delivery, backorder notices or unexpected 
delays, descriptions of actions taken to expedite delivery, and the 
current expected date of delivery.
    (E) If the reason for the extension is that the equipment cannot be 
installed without a process unit shutdown, include supporting 
documentation demonstrating that it is not practicable to isolate the 
equipment and install the monitoring instrument without a full process 
unit shutdown. Include the date of the most recent process unit 
shutdown, the frequency of shutdowns for this process unit, and the date 
of the next planned shutdown during which the monitoring equipment can 
be installed. If there has been a shutdown or if there is a planned 
process unit shutdown between promulgation of this part and April 1, 
2010, include a justification of why the equipment could not be obtained 
and installed during that shutdown.
    (F) A description of the specific actions the facility will take to 
obtain and install the equipment as soon as reasonably feasible and the 
expected date by which the equipment will be installed and operating.
    (iii) Approval criteria. To obtain approval, the owner or operator 
must demonstrate to the Administrator's satisfaction that it is not 
reasonably feasible to acquire, install, and operate a required piece of 
monitoring equipment by April 1, 2010. The use of best available methods 
will not be approved beyond December 31, 2010.
    (3) Abbreviated emissions report for facilities containing only 
general stationary fuel combustion sources. In lieu of the report 
required by paragraph (c) of this section, the owner or operator of an 
existing facility that is in operation on January 1, 2010 and that meets 
the conditions of Sec. 98.2(a)(3) may submit an abbreviated GHG report 
for the facility for GHGs emitted in 2010. The abbreviated report must 
be submitted by September 30, 2011. An owner or operator that submits an 
abbreviated report must submit a full GHG report according to the 
requirements of paragraph (c) of this section beginning in calendar year 
2012. The abbreviated facility report must include the following 
information:
    (i) Facility name and physical street address including the city, 
state and zip code.
    (ii) The year and months covered by the report.
    (iii) Date of submittal.
    (iv) Total facility GHG emissions aggregated for all stationary fuel 
combustion units calculated according to any method specified in Sec. 
98.33(a) and expressed in metric tons of CO2, CH4, 
N2O, and CO2e.

[[Page 565]]

    (v) For each stationary fuel combustion source that meets the 
criteria specified in Sec. 98.36(f), report any facility operating data 
or process information used for the GHG emission calculations. A 
stationary fuel combustion source that does not meet the criteria 
specified in Sec. 98.36(f) must either report the data specified in 
this paragraph (d)(3)(v) in the annual report or use verification 
software according to Sec. 98.5(b) in lieu of reporting the data 
specified in this paragraph.
    (vi) A signed and dated certification statement provided by the 
designated representative of the owner or operator, according to the 
requirements of paragraph (e)(1) of this section.
    (e) Emission calculations. In preparing the GHG report, you must use 
the calculation methodologies specified in the relevant subparts, except 
as specified in paragraph (d) of this section. For each source category, 
you must use the same calculation methodology throughout a reporting 
period unless you provide a written explanation of why a change in 
methodology was required.
    (f) Verification. To verify the completeness and accuracy of 
reported GHG emissions, the Administrator may review the certification 
statements described in paragraphs (c)(9) and (d)(3)(vi) of this section 
and any other credible evidence, in conjunction with a comprehensive 
review of the GHG reports and periodic audits of selected reporting 
facilities. Nothing in this section prohibits the Administrator from 
using additional information to verify the completeness and accuracy of 
the reports.
    (g) Recordkeeping. An owner or operator that is required to report 
GHGs under this part must keep records as specified in this paragraph 
(g). Except as otherwise provided in this paragraph, retain all required 
records for at least 3 years from the date of submission of the annual 
GHG report for the reporting year in which the record was generated. The 
records shall be kept in an electronic or hard-copy format (as 
appropriate) and recorded in a form that is suitable for expeditious 
inspection and review. If the owner or operator of a facility is 
required under Sec. 98.5(b) to use verification software specified by 
the Administrator, then all records required for the facility under this 
part must be retained for at least 5 years from the date of submission 
of the annual GHG report for the reporting year in which the record was 
generated, starting with records for reporting year 2010. Upon request 
by the Administrator, the records required under this section must be 
made available to EPA. Records may be retained off site if the records 
are readily available for expeditious inspection and review. For records 
that are electronically generated or maintained, the equipment or 
software necessary to read the records shall be made available, or, if 
requested by EPA, electronic records shall be converted to paper 
documents. You must retain the following records, in addition to those 
records prescribed in each applicable subpart of this part:
    (1) A list of all units, operations, processes, and activities for 
which GHG emission were calculated.
    (2) The data used to calculate the GHG emissions for each unit, 
operation, process, and activity, categorized by fuel or material type. 
These data include but are not limited to the following information in 
this paragraph (g)(2):
    (i) The GHG emissions calculations and methods used. For data 
required by Sec. 98.5(b) to be entered into verification software 
specified in Sec. 98.5(b), maintain the entered data in the format 
generated by the verification software according to Sec. 98.5(b).
    (ii) Analytical results for the development of site-specific 
emissions factors.
    (iii) The results of all required analyses for high heat value, 
carbon content, and other required fuel or feedstock parameters.
    (iv) Any facility operating data or process information used for the 
GHG emission calculations.
    (3) The annual GHG reports.
    (4) Missing data computations. For each missing data event, also 
retain a record of the cause of the event and the corrective actions 
taken to restore malfunctioning monitoring equipment.
    (5) A written GHG Monitoring Plan.

[[Page 566]]

    (i) At a minimum, the GHG Monitoring Plan shall include the elements 
listed in this paragraph (g)(5)(i).
    (A) Identification of positions of responsibility (i.e., job titles) 
for collection of the emissions data.
    (B) Explanation of the processes and methods used to collect the 
necessary data for the GHG calculations.
    (C) Description of the procedures and methods that are used for 
quality assurance, maintenance, and repair of all continuous monitoring 
systems, flow meters, and other instrumentation used to provide data for 
the GHGs reported under this part.
    (ii) The GHG Monitoring Plan may rely on references to existing 
corporate documents (e.g., standard operating procedures, quality 
assurance programs under appendix F to 40 CFR part 60 or appendix B to 
40 CFR part 75, and other documents) provided that the elements required 
by paragraph (g)(5)(i) of this section are easily recognizable.
    (iii) The owner or operator shall revise the GHG Monitoring Plan as 
needed to reflect changes in production processes, monitoring 
instrumentation, and quality assurance procedures; or to improve 
procedures for the maintenance and repair of monitoring systems to 
reduce the frequency of monitoring equipment downtime.
    (iv) Upon request by the Administrator, the owner or operator shall 
make all information that is collected in conformance with the GHG 
Monitoring Plan available for review during an audit. Electronic storage 
of the information in the plan is permissible, provided that the 
information can be made available in hard copy upon request during an 
audit.
    (6) The results of all required certification and quality assurance 
tests of continuous monitoring systems, fuel flow meters, and other 
instrumentation used to provide data for the GHGs reported under this 
part.
    (7) Maintenance records for all continuous monitoring systems, flow 
meters, and other instrumentation used to provide data for the GHGs 
reported under this part.
    (h) Annual GHG report revisions. This paragraph applies to the 
reporting years for which the owner or operator is required to maintain 
records for a facility or supplier according to the time periods 
specified in paragraph (g) of this section.
    (1) The owner or operator shall submit a revised annual GHG report 
within 45 days of discovering that an annual GHG report that the owner 
or operator previously submitted contains one or more substantive 
errors. The revised report must correct all substantive errors.
    (2) The Administrator may notify the owner or operator in writing 
that an annual GHG report previously submitted by the owner or operator 
contains one or more substantive errors. Such notification will identify 
each such substantive error. The owner or operator shall, within 45 days 
of receipt of the notification, either resubmit the report that, for 
each identified substantive error, corrects the identified substantive 
error (in accordance with the applicable requirements of this part) or 
provide information demonstrating that the previously submitted report 
does not contain the identified substantive error or that the identified 
error is not a substantive error.
    (3) A substantive error is an error that impacts the quantity of GHG 
emissions reported or otherwise prevents the reported data from being 
validated or verified.
    (4) Notwithstanding paragraphs (h)(1) and (2) of this section, upon 
request by the owner or operator, the Administrator may provide 
reasonable extensions of the 45-day period for submission of the revised 
report or information under paragraphs (h)(1) and (2). If the 
Administrator receives a request for extension of the 45-day period, by 
email to an address prescribed by the Administrator prior to the 
expiration of the 45-day period, the extension request is deemed to be 
automatically granted for 30 days. The Administrator may grant an 
additional extension beyond the automatic 30-day extension if the owner 
or operator submits a request for an additional extension and the 
request is received by the Administrator prior to the expiration of the 
automatic 30-day extension, provided the request demonstrates that it is 
not practicable to submit a revised report

[[Page 567]]

or information under paragraphs (h)(1) and (2) within 75 days. The 
Administrator will approve the extension request if the request 
demonstrates to the Administrator's satisfaction that it is not 
practicable to collect and process the data needed to resolve potential 
reporting errors identified pursuant to paragraph (h)(1) or (2) within 
75 days.
    (5) The owner or operator shall retain documentation for 3 years to 
support any revision made to an annual GHG report.
    (i) Calibration accuracy requirements. The owner or operator of a 
facility or supplier that is subject to the requirements of this part 
must meet the applicable flow meter calibration and accuracy 
requirements of this paragraph (i). The accuracy specifications in this 
paragraph (i) do not apply where either the use of company records (as 
defined in Sec. 98.6) or the use of ``best available information'' is 
specified in an applicable subpart of this part to quantify fuel usage 
and/or other parameters. Further, the provisions of this paragraph (i) 
do not apply to stationary fuel combustion units that use the 
methodologies in part 75 of this chapter to calculate CO2 
mass emissions.
    (1) Except as otherwise provided in paragraphs (i)(4) through (i)(6) 
of this section, flow meters that measure liquid and gaseous fuel feed 
rates, process stream flow rates, or feedstock flow rates and provide 
data for the GHG emissions calculations shall be calibrated prior to 
April 1, 2010 using the procedures specified in this paragraph (i) when 
such calibration is specified in a relevant subpart of this part. Each 
of these flow meters shall meet the applicable accuracy specification in 
paragraph (i)(2) or (i)(3) of this section. All other measurement 
devices (e.g., weighing devices) that are required by a relevant subpart 
of this part, and that are used to provide data for the GHG emissions 
calculations, shall also be calibrated prior to April 1, 2010; however, 
the accuracy specifications in paragraphs (i)(2) and (i)(3) of this 
section do not apply to these devices. Rather, each of these measurement 
devices shall be calibrated to meet the accuracy requirement specified 
for the device in the applicable subpart of this part, or, in the 
absence of such accuracy requirement, the device must be calibrated to 
an accuracy within the appropriate error range for the specific 
measurement technology, based on an applicable operating standard, 
including but not limited to manufacturer's specifications and industry 
standards. The procedures and methods used to quality-assure the data 
from each measurement device shall be documented in the written 
monitoring plan, pursuant to paragraph (g)(5)(i)(C) of this section.
    (i) All flow meters and other measurement devices that are subject 
to the provisions of this paragraph (i) must be calibrated according to 
one of the following: You may use the manufacturer's recommended 
procedures; an appropriate industry consensus standard method; or a 
method specified in a relevant subpart of this part. The calibration 
method(s) used shall be documented in the monitoring plan required under 
paragraph (g) of this section.
    (ii) For facilities and suppliers that become subject to this part 
after April 1, 2010, all flow meters and other measurement devices (if 
any) that are required by the relevant subpart(s) of this part to 
provide data for the GHG emissions calculations shall be installed no 
later than the date on which data collection is required to begin using 
the measurement device, and the initial calibration(s) required by this 
paragraph (i) (if any) shall be performed no later than that date.
    (iii) Except as otherwise provided in paragraphs (i)(4) through 
(i)(6) of this section, subsequent recalibrations of the flow meters and 
other measurement devices subject to the requirements of this paragraph 
(i) shall be performed at one of the following frequencies:
    (A) You may use the frequency specified in each applicable subpart 
of this part.
    (B) You may use the frequency recommended by the manufacturer or by 
an industry consensus standard practice, if no recalibration frequency 
is specified in an applicable subpart.
    (2) Perform all flow meter calibration at measurement points that 
are representative of the normal operating

[[Page 568]]

range of the meter. Except for the orifice, nozzle, and venturi flow 
meters described in paragraph (i)(3) of this section, calculate the 
calibration error at each measurement point using Equation A-2 of this 
section. The terms ``R'' and ``A'' in Equation A-2 must be expressed in 
consistent units of measure (e.g., gallons/minute, ft\3\/min). The 
calibration error at each measurement point shall not exceed 5.0 percent 
of the reference value.
[GRAPHIC] [TIFF OMITTED] TR17DE10.000

where:

CE = Calibration error (%).
R = Reference value.
A = Flow meter response to the reference value.

    (3) For orifice, nozzle, and venturi flow meters, the initial 
quality assurance consists of in-situ calibration of the differential 
pressure (delta-P), total pressure, and temperature transmitters.
    (i) Calibrate each transmitter at a zero point and at least one 
upscale point. Fixed reference points, such as the freezing point of 
water, may be used for temperature transmitter calibrations. Calculate 
the calibration error of each transmitter at each measurement point, 
using Equation A-3 of this subpart. The terms ``R,'' ``A,'' and ``FS'' 
in Equation A-3 of this subpart must be in consistent units of measure 
(e.g., milliamperes, inches of water, psi, degrees). For each 
transmitter, the CE value at each measurement point shall not exceed 2.0 
percent of full-scale. Alternatively, the results are acceptable if the 
sum of the calculated CE values for the three transmitters at each 
calibration level (i.e., at the zero level and at each upscale level) 
does not exceed 6.0 percent.
[GRAPHIC] [TIFF OMITTED] TR17DE10.001

where:
CE = Calibration error (%).
R = Reference value.
A = Transmitter response to the reference value.
FS = Full-scale value of the transmitter.

    (ii) In cases where there are only two transmitters (i.e., 
differential pressure and either temperature or total pressure) in the 
immediate vicinity of the flow meter's primary element (e.g., the 
orifice plate), or when there is only a differential pressure 
transmitter in close proximity to the primary element, calibration of 
these existing transmitters to a CE of 2.0 percent or less at each 
measurement point is still required, in accordance with paragraph 
(i)(3)(i) of this section; alternatively, when two transmitters are 
calibrated, the results are acceptable if the sum of the CE values for 
the two transmitters at each calibration level does not exceed 4.0 
percent. However, note that installation and calibration of an 
additional transmitter (or transmitters) at the flow monitor location to 
measure temperature or total pressure or both is not required in these 
cases. Instead, you may use assumed values for temperature and/or total 
pressure, based on measurements of these parameters at a remote location 
(or locations), provided that the following conditions are met:
    (A) You must demonstrate that measurements at the remote location(s) 
can, when appropriate correction factors are applied, reliably and 
accurately represent the actual temperature or total pressure at the 
flow

[[Page 569]]

meter under all expected ambient conditions.
    (B) You must make all temperature and/or total pressure measurements 
in the demonstration described in paragraph (i)(3)(ii)(A) of this 
section with calibrated gauges, sensors, transmitters, or other 
appropriate measurement devices. At a minimum, calibrate each of these 
devices to an accuracy within the appropriate error range for the 
specific measurement technology, according to one of the following. You 
may calibrate using a manufacturer's specification or an industry 
consensus standard.
    (C) You must document the methods used for the demonstration 
described in paragraph (i)(3)(ii)(A) of this section in the written GHG 
Monitoring Plan under paragraph (g)(5)(i)(C) of this section. You must 
also include the data from the demonstration, the mathematical 
correlation(s) between the remote readings and actual flow meter 
conditions derived from the data, and any supporting engineering 
calculations in the GHG Monitoring Plan. You must maintain all of this 
information in a format suitable for auditing and inspection.
    (D) You must use the mathematical correlation(s) derived from the 
demonstration described in paragraph (i)(3)(ii)(A) of this section to 
convert the remote temperature or the total pressure readings, or both, 
to the actual temperature or total pressure at the flow meter, or both, 
on a daily basis. You shall then use the actual temperature and total 
pressure values to correct the measured flow rates to standard 
conditions.
    (E) You shall periodically check the correlation(s) between the 
remote and actual readings (at least once a year), and make any 
necessary adjustments to the mathematical relationship(s).
    (4) Fuel billing meters are exempted from the calibration 
requirements of this section and from the GHG Monitoring Plan and 
recordkeeping provisions of paragraphs (g)(5)(i)(C), (g)(6), and (g)(7) 
of this section, provided that the fuel supplier and any unit combusting 
the fuel do not have any common owners and are not owned by subsidiaries 
or affiliates of the same company. Meters used exclusively to measure 
the flow rates of fuels that are used for unit startup are also exempted 
from the calibration requirements of this section.
    (5) For a flow meter that has been previously calibrated in 
accordance with paragraph (i)(1) of this section, an additional 
calibration is not required by the date specified in paragraph (i)(1) of 
this section if, as of that date, the previous calibration is still 
active (i.e., the device is not yet due for recalibration because the 
time interval between successive calibrations has not elapsed). In this 
case, the deadline for the successive calibrations of the flow meter 
shall be set according to one of the following. You may use either the 
manufacturer's recommended calibration schedule or you may use the 
industry consensus calibration schedule.
    (6) For units and processes that operate continuously with 
infrequent outages, it may not be possible to meet the April 1, 2010 
deadline for the initial calibration of a flow meter or other 
measurement device without disrupting normal process operation. In such 
cases, the owner or operator may postpone the initial calibration until 
the next scheduled maintenance outage. The best available information 
from company records may be used in the interim. The subsequent required 
recalibrations of the flow meters may be similarly postponed. Such 
postponements shall be documented in the monitoring plan that is 
required under paragraph (g)(5) of this section.
    (7) If the results of an initial calibration or a recalibration fail 
to meet the required accuracy specification, data from the flow meter 
shall be considered invalid, beginning with the hour of the failed 
calibration and continuing until a successful calibration is completed. 
You shall follow the missing data provisions provided in the relevant 
missing data sections during the period of data invalidation.
    (j) Measurement device installation--(1) General. If an owner or 
operator required to report under subpart P, subpart X or subpart Y of 
this part has process equipment or units that operate continuously and 
it is not possible to install a required flow meter or other measurement 
device by April 1,

[[Page 570]]

2010, (or by any later date in 2010 approved by the Administrator as 
part of an extension of best available monitoring methods per paragraph 
(d) of this section) without process equipment or unit shutdown, or 
through a hot tap, the owner or operator may request an extension from 
the Administrator to delay installing the measurement device until the 
next scheduled process equipment or unit shutdown. If approval for such 
an extension is granted by the Administrator, the owner or operator must 
use best available monitoring methods during the extension period.
    (2) Requests for extension of the use of best available monitoring 
methods for measurement device installation. The owner or operator must 
first provide the Administrator an initial notification of the intent to 
submit an extension request for use of best available monitoring methods 
beyond December 31, 2010 (or an earlier date approved by EPA) in cases 
where measurement device installation would require a process equipment 
or unit shutdown, or could only be done through a hot tap. The owner or 
operator must follow-up this initial notification with the complete 
extension request containing the information specified in paragraph 
(j)(4) of this section.
    (3) Timing of request. (i) The initial notice of intent must be 
submitted no later than January 1, 2011, or by the end of the approved 
use of best available monitoring methods extension in 2010, whichever is 
earlier. The completed extension request must be submitted to the 
Administrator no later than February 15, 2011.
    (ii) Any subsequent extensions to the original request must be 
submitted to the Administrator within 4 weeks of the owner or operator 
identifying the need to extend the request, but in any event no later 
than 4 weeks before the date for the planned process equipment or unit 
shutdown that was provided in the original or most recently approved 
request.
    (4) Content of the request. Requests must contain the following 
information:
    (i) Specific measurement device for which the request is being made 
and the location where each measurement device will be installed.
    (ii) Identification of the specific rule requirements (by rule 
subpart, section, and paragraph numbers) requiring the measurement 
device.
    (iii) A description of the reasons why the needed equipment could 
not be installed before April 1, 2010, or by the expiration date for the 
use of best available monitoring methods, in cases where an extension 
has been granted under Sec. 98.3(d).
    (iv) Supporting documentation showing that it is not practicable to 
isolate the process equipment or unit and install the measurement device 
without a full shutdown or a hot tap, and that there was no opportunity 
during 2010 to install the device. Include the date of the three most 
recent shutdowns for each relevant process equipment or unit, the 
frequency of shutdowns for each relevant process equipment or unit, and 
the date of the next planned process equipment or unit shutdown.
    (v) Include a description of the proposed best available monitoring 
method for estimating GHG emissions during the time prior to 
installation of the meter.
    (5) Approval criteria. The owner or operator must demonstrate to the 
Administrator's satisfaction that it is not reasonably feasible to 
install the measurement device before April 1, 2010 (or by the 
expiration date for the use of best available monitoring methods, in 
cases where an extension has been granted under paragraph (d) of this 
section) without a process equipment or unit shutdown, or through a hot 
tap, and that the proposed method for estimating GHG emissions during 
the time before which the measurement device will be installed is 
appropriate. The Administrator will not initially approve the use of the 
proposed best available monitoring method past December 31, 2013.
    (6) Measurement device installation deadline. Any owner or operator 
that submits both a timely initial notice of intent and a timely 
completed extension request under paragraph (j)(3) of this section to 
extend use of best available monitoring methods for measurement device 
installation must install all such devices by July 1, 2011 unless

[[Page 571]]

the extension request under this paragraph (j) is approved by the 
Administrator before July 1, 2011.
    (7) One time extension past December 31, 2013. If an owner or 
operator determines that a scheduled process equipment or unit shutdown 
will not occur by December 31, 2013, the owner or operator may re-apply 
to use best available monitoring methods for one additional time period, 
not to extend beyond December 31, 2015. To extend use of best available 
monitoring methods past December 31, 2013, the owner or operator must 
submit a new extension request by June 1, 2013 that contains the 
information required in paragraph (j)(4) of this section. The owner or 
operator must demonstrate to the Administrator's satisfaction that it 
continues to not be reasonably feasible to install the measurement 
device before December 31, 2013 without a process equipment or unit 
shutdown, or that installation of the measurement device could only be 
done through a hot tap, and that the proposed method for estimating GHG 
emissions during the time before which the measurement device will be 
installed is appropriate. An owner or operator that submits a request 
under this paragraph to extend use of best available monitoring methods 
for measurement device installation must install all such devices by 
December 31, 2013, unless the extension request under this paragraph is 
approved by the Administrator.
    (k) Revised global warming potentials and special provisions for 
reporting year 2013 and subsequent reporting years. This paragraph (k) 
applies to owners or operators of facilities or suppliers that first 
become subject to any subpart of part 98 solely due to an amendment to 
Table A-1 of this subpart.
    (1) A facility or supplier that first becomes subject to part 98 due 
to a change in the GWP for one or more compounds in Table A-1 of this 
subpart, Global Warming Potentials, is not required to submit an annual 
GHG report for the reporting year during which the change in GWPs is 
published.
    (2) A facility or supplier that was already subject to one or more 
subparts of part 98 but becomes subject to one or more additional 
subparts due to a change in the GWP for one or more compounds in Table 
A-1 of this subpart, is not required to include those subparts to which 
the facility is subject only due to the change in the GWP in the annual 
GHG report submitted for the reporting year during which the change in 
GWPs is published.
    (3) Starting on January 1 of the year after the year during which 
the change in GWPs is published, facilities or suppliers identified in 
paragraphs (k)(1) or (2) of this section must start monitoring and 
collecting GHG data in compliance with the applicable subparts of part 
98 to which the facility is subject due to the change in the GWP for the 
annual greenhouse gas report for that reporting year, which is due by 
March 31 of the following calendar year.
    (4) A change in the GWP for one or more compounds includes the 
addition to Table A-1 of this subpart of either a chemical-specific or a 
default GWP that applies to a compound to which no chemical-specific GWP 
in Table A-1 of this subpart previously applied.
    (l) Special provision for best available monitoring methods in 2014 
and subsequent years. This paragraph (l) applies to owners or operators 
of facilities or suppliers that first become subject to any subpart of 
part 98 due to an amendment to Table A-1 of this subpart, Global Warming 
Potentials.
    (1) Best available monitoring methods. From January 1 to March 31 of 
the year after the year during which the change in GWPs is published, 
owners or operators subject to this paragraph (l) may use best available 
monitoring methods for any parameter (e.g., fuel use, feedstock rates) 
that cannot reasonably be measured according to the monitoring and QA/QC 
requirements of a relevant subpart. The owner or operator must use the 
calculation methodologies and equations in the ``Calculating GHG 
Emissions'' sections of each relevant subpart, but may use the best 
available monitoring method for any parameter for which it is not 
reasonably feasible to acquire, install, and operate a required piece of 
monitoring equipment by January 1 of the year after the year during 
which the change in GWPs is published. Starting no later than April 1 of 
the year after the year during which the change in GWPs is published,

[[Page 572]]

the owner or operator must discontinue using best available methods and 
begin following all applicable monitoring and QA/QC requirements of this 
part, except as provided in paragraph (l)(2) of this section. Best 
available monitoring methods means any of the following methods:
    (i) Monitoring methods currently used by the facility that do not 
meet the specifications of a relevant subpart.
    (ii) Supplier data.
    (iii) Engineering calculations.
    (iv) Other company records.
    (2) Requests for extension of the use of best available monitoring 
methods. The owner or operator may submit a request to the Administrator 
to use one or more best available monitoring methods beyond March 31 of 
the year after the year during which the change in GWPs is published.
    (i) Timing of request. The extension request must be submitted to 
EPA no later than January 31 of the year after the year during which the 
change in GWPs is published.
    (ii) Content of request. Requests must contain the following 
information:
    (A) A list of specific items of monitoring instrumentation for which 
the request is being made and the locations where each piece of 
monitoring instrumentation will be installed.
    (B) Identification of the specific rule requirements (by rule 
subpart, section, and paragraph numbers) for which the instrumentation 
is needed.
    (C) A description of the reasons that the needed equipment could not 
be obtained and installed before April 1 of the year after the year 
during which the change in GWPs is published.
    (D) If the reason for the extension is that the equipment cannot be 
purchased and delivered by April 1 of the year after the year during 
which the change in GWPs is published, include supporting documentation 
such as the date the monitoring equipment was ordered, investigation of 
alternative suppliers and the dates by which alternative vendors 
promised delivery, backorder notices or unexpected delays, descriptions 
of actions taken to expedite delivery, and the current expected date of 
delivery.
    (E) If the reason for the extension is that the equipment cannot be 
installed without a process unit shutdown, include supporting 
documentation demonstrating that it is not practicable to isolate the 
equipment and install the monitoring instrument without a full process 
unit shutdown. Include the date of the most recent process unit 
shutdown, the frequency of shutdowns for this process unit, and the date 
of the next planned shutdown during which the monitoring equipment can 
be installed. If there has been a shutdown or if there is a planned 
process unit shutdown between November 29 of the year during which the 
change in GWPs is published and April 1 of the year after the year 
during which the change in GWPs is published, include a justification of 
why the equipment could not be obtained and installed during that 
shutdown.
    (F) A description of the specific actions the facility will take to 
obtain and install the equipment as soon as reasonably feasible and the 
expected date by which the equipment will be installed and operating.
    (iii) Approval criteria. To obtain approval, the owner or operator 
must demonstrate to the Administrator's satisfaction that it is not 
reasonably feasible to acquire, install, and operate a required piece of 
monitoring equipment by April 1 of the year after the year during which 
the change in GWPs is published. The use of best available methods under 
this paragraph (l) will not be approved beyond December 31 of the year 
after the year during which the change in GWPs is published.

Sec. 98.4  Authorization and responsibilities of the designated 
representative.

    (a) General. Except as provided under paragraph (f) of this section, 
each facility, and each supplier, that is subject to this part, shall 
have one and only one designated representative, who

[[Page 573]]

shall be responsible for certifying, signing, and submitting GHG 
emissions reports and any other submissions for such facility and 
supplier respectively to the Administrator under this part. If the 
facility is required under any other part of title 40 of the Code of 
Federal Regulations to submit to the Administrator any other emission 
report that is subject to any requirement in 40 CFR part 75, the same 
individual shall be the designated representative responsible for 
certifying, signing, and submitting the GHG emissions reports and all 
such other emissions reports under this part.
    (b) Authorization of a designated representative. The designated 
representative of the facility or supplier shall be an individual 
selected by an agreement binding on the owners and operators of such 
facility or supplier and shall act in accordance with the certification 
statement in paragraph (i)(4)(iv) of this section.
    (c) Responsibility of the designated representative. Upon receipt by 
the Administrator of a complete certificate of representation under this 
section for a facility or supplier, the designated representative 
identified in such certificate of representation shall represent and, by 
his or her representations, actions, inactions, or submissions, legally 
bind each owner and operator of such facility or supplier in all matters 
pertaining to this part, notwithstanding any agreement between the 
designated representative and such owners and operators. The owners and 
operators shall be bound by any decision or order issued to the 
designated representative by the Administrator or a court.
    (d) Timing. No GHG emissions report or other submissions under this 
part for a facility or supplier will be accepted until the Administrator 
has received a complete certificate of representation under this section 
for a designated representative of the facility or supplier. Such 
certificate of representation shall be submitted at least 60 days before 
the deadline for submission of the facility's or supplier's initial 
emission report under this part.
    (e) Certification of the GHG emissions report. Each GHG emission 
report and any other submission under this part for a facility or 
supplier shall be certified, signed, and submitted by the designated 
representative or any alternate designated representative of the 
facility or supplier in accordance with this section and Sec. 3.10 of 
this chapter.
    (1) Each such submission shall include the following certification 
statement signed by the designated representative or any alternate 
designated representative: ``I am authorized to make this submission on 
behalf of the owners and operators of the facility or supplier, as 
applicable, for which the submission is made. I certify under penalty of 
law that I have personally examined, and am familiar with, the 
statements and information submitted in this document and all its 
attachments. Based on my inquiry of those individuals with primary 
responsibility for obtaining the information, I certify that the 
statements and information are to the best of my knowledge and belief 
true, accurate, and complete. I am aware that there are significant 
penalties for submitting false statements and information or omitting 
required statements and information, including the possibility of fine 
or imprisonment.''
    (2) The Administrator will accept a GHG emission report or other 
submission for a facility or supplier under this part only if the 
submission is certified, signed, and submitted in accordance with this 
section.
    (f) Alternate designated representative. A certificate of 
representation under this section for a facility or supplier may 
designate one alternate designated representative, who shall be an 
individual selected by an agreement binding on the owners and operators, 
and may act on behalf of the designated representative, of such facility 
or supplier. The agreement by which the alternate designated 
representative is selected shall include a procedure for authorizing the 
alternate designated representative to act in lieu of the designated 
representative.
    (1) Upon receipt by the Administrator of a complete certificate of 
representation under this section for a facility or supplier identifying 
an alternate designated representative.
    (i) The alternate designated representative may act on behalf of the

[[Page 574]]

designated representative for such facility or supplier.
    (ii) Any representation, action, inaction, or submission by the 
alternate designated representative shall be deemed to be a 
representation, action, inaction, or submission by the designated 
representative.
    (2) Except in this section, whenever the term ``designated 
representative'' is used in this part, the term shall be construed to 
include the designated representative or any alternate designated 
representative.
    (g) Changing a designated representative or alternate designated 
representative. The designated representative or alternate designated 
representative identified in a complete certificate of representation 
under this section for a facility or supplier received by the 
Administrator may be changed at any time upon receipt by the 
Administrator of another later signed, complete certificate of 
representation under this section for the facility or supplier. 
Notwithstanding any such change, all representations, actions, 
inactions, and submissions by the previous designated representative or 
the previous alternate designated representative of the facility or 
supplier before the time and date when the Administrator receives such 
later signed certificate of representation shall be binding on the new 
designated representative and the owners and operators of the facility 
or supplier.
    (h) Changes in owners and operators. In the event an owner or 
operator of the facility or supplier is not included in the list of 
owners and operators in the certificate of representation under this 
section for the facility or supplier, such owner or operator shall be 
deemed to be subject to and bound by the certificate of representation, 
the representations, actions, inactions, and submissions of the 
designated representative and any alternate designated representative of 
the facility or supplier, as if the owner or operator were included in 
such list. Within 90 days after any change in the owners and operators 
of the facility or supplier (including the addition of a new owner or 
operator), the designated representative or any alternate designated 
representative shall submit a certificate of representation that is 
complete under this section except that such list shall be amended to 
reflect the change. If the designated representative or alternate 
designated representative determines at any time that an owner or 
operator of the facility or supplier is not included in such list and 
such exclusion is not the result of a change in the owners and 
operators, the designated representative or any alternate designated 
representative shall submit, within 90 days of making such 
determination, a certificate of representation that is complete under 
this section except that such list shall be amended to include such 
owner or operator.
    (i) Certificate of representation. A certificate of representation 
shall be complete if it includes the following elements in a format 
prescribed by the Administrator in accordance with this section:
    (1) Identification of the facility or supplier for which the 
certificate of representation is submitted.
    (2) The name, organization name (company affiliation-employer), 
address, e-mail address (if any), telephone number, and facsimile 
transmission number (if any) of the designated representative and any 
alternate designated representative.
    (3) A list of the owners and operators of the facility or supplier 
identified in paragraph (i)(1) of this section, provided that, if the 
list includes the operators of the facility or supplier and the owners 
with control of the facility or supplier, the failure to include any 
other owners shall not make the certificate of representation 
incomplete.
    (4) The following certification statements by the designated 
representative and any alternate designated representative:
    (i) ``I certify that I was selected as the designated representative 
or alternate designated representative, as applicable, by an agreement 
binding on the owners and operators of the facility or supplier, as 
applicable.''
    (ii) ``I certify that I have all the necessary authority to carry 
out my duties and responsibilities under 40 CFR part 98 on behalf of the 
owners and operators of the facility or supplier, as applicable, and 
that each such owner

[[Page 575]]

and operator shall be fully bound by my representations, actions, 
inactions, or submissions.''
    (iii) ``I certify that the owners and operators of the facility or 
supplier, as applicable, shall be bound by any order issued to me by the 
Administrator or a court regarding the facility or supplier.''
    (iv) ``If there are multiple owners and operators of the facility or 
supplier, as applicable, I certify that I have given a written notice of 
my selection as the `designated representative' or `alternate designated 
representative', as applicable, and of the agreement by which I was 
selected to each owner and operator of the facility or supplier.''
    (5) The signature of the designated representative and any alternate 
designated representative and the dates signed.
    (6) A list of the subparts that the owners and operators anticipate 
will be included in the annual GHG report. The list of potentially 
applicable subparts is required only for an initial certificate of 
representation that is submitted after January 1, 2018 (i.e., for a 
facility or supplier that previously was not registered under this 
part). The list of potentially applicable subparts does not need to be 
revised with revisions to the COR or if the actual applicable subparts 
change.
    (j) Documents of agreement. Unless otherwise required by the 
Administrator, documents of agreement referred to in the certificate of 
representation shall not be submitted to the Administrator. The 
Administrator shall not be under any obligation to review or evaluate 
the sufficiency of such documents, if submitted.
    (k) Binding nature of the certificate of representation. Once a 
complete certificate of representation under this section for a facility 
or supplier has been received, the Administrator will rely on the 
certificate of representation unless and until a later signed, complete 
certificate of representation under this section for the facility or 
supplier is received by the Administrator.
    (l) Objections concerning a designated representative. (1) Except as 
provided in paragraph (g) of this section, no objection or other 
communication submitted to the Administrator concerning the 
authorization, or any representation, action, inaction, or submission, 
of the designated representative or alternate designated representative 
shall affect any representation, action, inaction, or submission of the 
designated representative or alternate designated representative, or the 
finality of any decision or order by the Administrator under this part.
    (2) The Administrator will not adjudicate any private legal dispute 
concerning the authorization or any representation, action, inaction, or 
submission of any designated representative or alternate designated 
representative.
    (m) Delegation by designated representative and alternate designated 
representative. (1) A designated representative or an alternate 
designated representative may delegate his or her own authority, to one 
or more individuals, to submit an electronic submission to the 
Administrator provided for or required under this part, except for a 
submission under this paragraph.
    (2) In order to delegate his or her own authority, to one or more 
individuals, to submit an electronic submission to the Administrator in 
accordance with paragraph (m)(1) of this section, the designated 
representative or alternate designated representative must submit 
electronically to the Administrator a notice of delegation, in a format 
prescribed by the Administrator, that includes the following elements:
    (i) The name, organization name (company affiliation-employer) 
address, e-mail address (if any), telephone number, and facsimile

Subpart B [Reserved]



          Subpart C_General Stationary Fuel Combustion Sources



Sec. 98.30  Definition of the source category.

    (a) Stationary fuel combustion sources are devices that combust 
solid, liquid, or gaseous fuel, generally for the purposes of producing 
electricity, generating steam, or providing useful heat or energy for 
industrial, commercial, or institutional use, or reducing the volume of 
waste by removing combustible matter. Stationary fuel combustion sources 
include, but are not limited to, boilers, simple and combined-cycle 
combustion turbines, engines, incinerators, and process heaters.
    (b) This source category does not include:
    (1) Portable equipment, as defined in Sec. 98.6.
    (2) Emergency generators and emergency equipment, as defined in 
Sec. 98.6.
    (3) Irrigation pumps at agricultural operations.
    (4) Flares, unless otherwise required by provisions of another 
subpart of this part to use methodologies in this subpart.
    (5) Electricity generating units that are subject to subpart D of 
this part.
    (c) For a unit that combusts hazardous waste (as defined in Sec. 
261.3 of this chapter), reporting of GHG emissions is not required 
unless either of the following conditions apply:
    (1) Continuous emission monitors (CEMS) are used to quantify 
CO2 mass emissions.
    (2) Any fuel listed in Table C-1 of this subpart is also combusted 
in the unit. In this case, report GHG emissions from combustion of all 
fuels listed in Table C-1 of this subpart.
    (d) You are not required to report GHG emissions from pilot lights. 
A pilot light is a small auxiliary flame that ignites the burner of a 
combustion device when the control valve opens.

is specified in Sec. 98.34. The method for computing the annual average 
HHV is a function of unit size and how frequently you perform or receive 
from the fuel supplier the results of fuel sampling for HHV. The method 
is specified in paragraph (a)(2)(ii)(A) or (a)(2)(ii)(B) of this 
section, as applicable.
    (A) If the results of fuel sampling are received monthly or more 
frequently, then for each unit with a maximum rated heat input capacity 
greater than or equal to 100 mmBtu/hr (or for a group of units that 
includes at least one unit of that size), the annual average HHV shall 
be calculated using Equation C-2b of this section. If multiple HHV 
determinations are made in any month, average the values for the month 
arithmetically.

          data value (mmBtu per mass or volume).
(Fuel)I = Mass or volume of the fuel combusted during the 
          sample period ``i,'' (e.g., monthly, quarterly, semi-annually,

          for solid fuel, volume in standard cubic feet (e.g., for 
          gaseous fuel, and volume in gallons for liquid fuel).

than monthly, or, for a unit with a maximum rated heat input capacity 
less than 100 mmBtu/hr (or a group of such units) regardless of the HHV 
sampling frequency, the annual average HHV shall either be computed 
according to paragraph (a)(2)(ii)(A) of this section or as

the arithmetic average HHV for all values for the year (including valid 
samples and substitute data values under Sec. 98.35).
    (iii) For units that combust municipal solid waste (MSW) and that 
produce steam, use Equation C-2c of this section. Equation C-2c of this

          1 of this subpart (kg CO2/mmBtu).
1 x 10-3 = Conversion factor from kilograms to metric tons.

    (3) Tier 3 Calculation Methodology. Calculate the annual 
CO2 mass emissions for each fuel by using either Equation C3,

          may also be used.
CC = Annual average carbon content of the liquid fuel (kg C per gallon 
          of fuel). The annual average carbon content shall be 
          determined using the same procedures as specified for HHV in

          The annual average molecular weight shall be determined using 
          the same procedures as specified for HHV in paragraph 
          (a)(2)(ii) of this section.
MVC = Molar volume conversion factor at standard conditions, as defined 
          in Sec. 98.6. Use 849.5 scf per kg mole if you select 68 
          [deg]F as standard temperature and 836.6 scf per kg mole if 
          you select 60 [deg]F as standard temperature.
44/12 = Ratio of molecular weights, CO2 to carbon.
0.001 = Conversion factor from kg to metric tons.

    (iv) Fuel flow meters that measure mass flow rates may be used for 
liquid or gaseous fuels, provided that the fuel density is used to 
convert the readings to volumetric flow rates. The density shall be 
measured at the same frequency as the carbon content. You must measure 
the density using one of the following appropriate methods. You may use 
a method published by a consensus-based standards organization, if such 
a method exists, or you may use industry standard practice. Consensus-
based standards organizations include, but are not limited to, the 
following: ASTM International (100 Barr Harbor Drive, P.O. Box CB700, 
West Conshohocken, Pennsylvania 19428-B2959, (800) 262-1373, http://
www.astm.org), the American National Standards Institute (ANSI, 1819 L 
Street, NW., 6th floor, Washington, DC 20036, (202) 293-8020, http://
www.ansi.org), the American Gas Association (AGA), 400 North Capitol 
Street, NW., 4th Floor, Washington, DC 20001, (202) 824-7000, http://
www.aga.org), the American Society of Mechanical Engineers (ASME, Three 
Park Avenue, New York, NY 10016-5990, (800) 843-2763, http://
www.asme.org), the American Petroleum Institute (API, 1220 L Street, 
NW., Washington, DC 20005-4070, (202) 682-8000, http://www.api.org), and 
the North American Energy Standards Board (NAESB, 801 Travis Street, 
Suite 1675, Houston, TX 77002, (713) 356-0060, http://www.api.org). The 
method(s) used shall be documented in the GHG Monitoring Plan required 
under Sec. 98.3(g)(5).
    (v) The following default density values may be used for fuel oil, 
in lieu of using the methods in paragraph (a)(3)(iv) of this section: 
6.8 lb/gal for No. 1 oil; 7.2 lb/gal for No. 2 oil; 8.1 lb/gal for No. 6 
oil.
    (4) Tier 4 Calculation Methodology. Calculate the annual 
CO2 mass emissions from all fuels combusted in a unit, by 
using quality-assured data from continuous emission monitoring systems 
(CEMS).
    (i) This methodology requires a CO2 concentration monitor 
and a stack gas volumetric flow rate monitor, except as otherwise 
provided in paragraph (a)(4)(iv) of this section. Hourly measurements of 
CO2 concentration and stack gas flow rate are converted to 
CO2 mass emission rates in metric tons per hour.
    (ii) When the CO2 concentration is measured on a wet 
basis, Equation C-6 of this section is used to calculate the hourly 
CO2 emission rates:
[GRAPHIC] [TIFF OMITTED] TR30OC09.011

Where:

CO2 = CO2 mass emission rate (metric tons/hr).

[[Page 619]]

CCO2 = Hourly average CO2 concentration (% 
          CO2).
Q = Hourly average stack gas volumetric flow rate (scfh).
5.18 x 10-7 = Conversion factor (metric tons/scf/% 
          CO2).

    (iii) If the CO2 concentration is measured on a dry 
basis, a correction for the stack gas moisture content is required. You 
shall either continuously monitor the stack gas moisture content using a 
method described in Sec. 75.11(b)(2) of this chapter or use an 
appropriate default moisture percentage. For coal, wood, and natural gas 
combustion, you may use the default moisture values specified in Sec. 
75.11(b)(1) of this chapter. Alternatively, for any type of fuel, you 
may determine an appropriate site-specific default moisture value (or 
values), using measurements made with EPA Method 4--Determination Of 
Moisture Content In Stack Gases, in appendix A-3 to part 60 of this 
chapter. Moisture data from the relative accuracy test audit (RATA) of a 
CEMS may be used for this purpose. If this option is selected, the site-
specific moisture default value(s) must represent the fuel(s) or fuel 
blends that are combusted in the unit during normal, stable operation, 
and must account for any distinct difference(s) in the stack gas 
moisture content associated with different process operating conditions. 
For each site-specific default moisture percentage, at least nine Method 
4 runs are required, except where the option to use moisture data from a 
RATA is selected, and the applicable regulation allows a single moisture 
determination to represent two or more RATA runs. In that case, you may 
base the site-specific moisture percentage on the number of moisture 
runs allowed by the RATA regulation. Calculate each site-specific 
default moisture value by taking the arithmetic average of the Method 4 
runs. Each site-specific moisture default value shall be updated 
whenever the owner or operator believes the current value is non-
representative, due to changes in unit or process operation, but in any 
event no less frequently than annually. Use the updated moisture value 
in the subsequent CO2 emissions calculations. For each unit 
operating hour, a moisture correction must be applied to Equation C-6 of 
this section as follows:
[GRAPHIC] [TIFF OMITTED] TR17DE10.002

where:

CO2* = Hourly CO2 mass emission rate, corrected 
          for moisture (metric tons/hr).
CO2 = Hourly CO2 mass emission rate from Equation 
          C-6 of this section, uncorrected (metric tons/hr).
%H2O = Hourly moisture percentage in the stack gas (measured 
          or default value, as appropriate).

    (iv) An oxygen (O2) concentration monitor may be used in 
lieu of a CO2 concentration monitor to determine the hourly 
CO2 concentrations, in accordance with Equation F-14a or F-
14b (as applicable) in appendix F to part 75 of this chapter, if the 
effluent gas stream monitored by the CEMS consists solely of combustion 
products (i.e., no process CO2 emissions or CO2 
emissions from sorbent are mixed with the combustion products) and if 
only fuels that are listed in Table 1 in section 3.3.5 of appendix F to 
part 75 of this chapter are combusted in the unit. If the O2 
monitoring option is selected, the F-factors used in Equations F-14a and 
F-14b shall be determined according to section 3.3.5 or section 3.3.6 of 
appendix F to part 75 of this chapter, as applicable. If Equation F-14b 
is used, the hourly moisture percentage in the stack gas shall be 
determined in accordance with paragraph (a)(4)(iii) of this section.
    (v) Each hourly CO2 mass emission rate from Equation C-6 
or C-7 of this section is multiplied by the operating time to convert it 
from metric tons per hour to metric tons. The operating time is the 
fraction of the hour during which fuel is combusted (e.g., the unit

[[Page 620]]

operating time is 1.0 if the unit operates for the whole hour and is 0.5 
if the unit operates for 30 minutes in the hour). For common stack 
configurations, the operating time is the fraction of the hour during 
which effluent gases flow through the common stack.
    (vi) The hourly CO2 mass emissions are then summed over 
each calendar quarter and the quarterly totals are summed to determine 
the annual CO2 mass emissions.
    (vii) If both biomass and fossil fuel are combusted during the year, 
determine and report the biogenic CO2 mass emissions 
separately, as described in paragraph (e) of this section.
    (viii) If a portion of the flue gases generated by a unit subject to 
Tier 4 (e.g., a slip stream) is continuously diverted from the main flue 
gas exhaust system for the purpose of heat recovery or some other 
similar process, and then exhausts through a stack that is not equipped 
with the continuous emission monitors to measure CO2 mass 
emissions, CO2 emissions shall be determined as follows:
    (A) At least once a year, use EPA Methods 2 and 3A, and (if 
necessary) Method 4 in appendices A-2 and A-3 to part 60 of this chapter 
to perform emissions testing at a set point that best represents normal, 
stable process operating conditions. A minimum of three one-hour Method 
3A tests are required, to determine the CO2 concentration. A 
Method 2 test shall be performed during each Method 3A run, to determine 
the stack gas volumetric flow rate. If moisture correction is necessary, 
a Method 4 run shall also be performed during each Method 3A run. 
Important parametric information related to the stack gas flow rate 
(e.g., damper positions, fan settings, etc.) shall also be recorded 
during the test.
    (B) Calculate a CO2 mass emission rate (in metric tons/
hr) from the stack test data, using a version of Equation C-6 in 
paragraph (a)(4)(ii) of this section, modified as follows. In the 
Equation C-6 nomenclature, replace the words ``Hourly average'' in the 
definitions of ``CCO2'' and ``Q'' with the words ``3-run 
average''. Substitute the arithmetic average values of CO2 
concentration and stack gas flow rate from the emission testing into 
modified Equation C-6. If CO2 is measured on a dry basis, a 
moisture correction of the calculated CO2 mass emission rate 
is required. Use Equation C-7 in paragraph (a)(4)(ii) of this section to 
make this correction; replace the word ``Hourly'' with the words ``3-run 
average'' in the equation nomenclature.
    (C) The results of each annual stack test shall be used in the GHG 
emissions calculations for the year of the test.
    (D) If, for the majority of the operating hours during the year, the 
diverted stream is withdrawn at a steady rate at or near the tested set 
point (as evidenced by fan and damper settings and/or other parameters), 
you may use the calculated CO2 mass emission rate from 
paragraph (a)(4)(viii)(B) of this section to estimate the CO2 
mass emissions for all operating hours in which flue gas is diverted 
from the main exhaust system. Otherwise, you must account for the 
variation in the flow rate of the diverted stream, as described in 
paragraph (c)(4)(viii)(E) of this section.
    (E) If the flow rate of the diverted stream varies significantly 
throughout the year, except as provided below, repeat the stack test and 
emission rate calculation procedures described in paragraphs 
(c)(4)(viii)(A) and (c)(4)(viii)(B) of this section at a minimum of two 
more set points across the range of typical operating conditions to 
develop a correlation between CO2 mass emission rate and the 
parametric data. If additional testing is not feasible, use the 
following approach to develop the necessary correlation. Assume that the 
average CO2 concentration obtained in the annual stack test 
is the same at all operating set points. Then, beginning with the 
measured flow rate from the stack test and the associated parametric 
data, perform an engineering analysis to estimate the stack gas flow 
rate at two or more additional set points. Calculate the CO2 
mass emission rate at each set point.
    (F) Calculate the annual CO2 mass emissions for the 
diverted stream as follows. For a steady-state process, multiply the 
number of hours in which flue gas was diverted from the main exhaust 
system by the CO2 mass emission rate from the stack test. 
Otherwise, using the best available information and engineering 
judgment, apply the

[[Page 621]]

most representative CO2 mass emission rate from the 
correlation in paragraph (c)(4)(viii)(E) of this section to determine 
the CO2 mass emissions for each hour in which flue gas was 
diverted, and sum the results. To simplify the calculations, you may 
count partial operating hours as full hours.
    (G) Finally, add the CO2 mass emissions from 
paragraph(c)(4)(viii)(F) of this section to the annual CO2 
mass emissions measured by the CEMS at the main stack. Report this sum 
as the total annual CO2 mass emissions for the unit.
    (H) The exact method and procedures used to estimate the 
CO2 mass emissions for the diverted portion of the flue gas 
exhaust stream shall be documented in the Monitoring Plan required under 
Sec. 98.3(g)(5).
    (5) Alternative methods for certain units subject to Part 75 of this 
chapter. Certain units that are not subject to subpart D of this part 
and that report data to EPA according to part 75 of this chapter may 
qualify to use the alternative methods in this paragraph (a)(5), in lieu 
of using any of the four calculation methodology tiers.
    (i) For a unit that combusts only natural gas and/or fuel oil, is 
not subject to subpart D of this part, monitors and reports heat input 
data year-round according to appendix D to part 75 of this chapter, but 
is not required by the applicable part 75 program to report 
CO2 mass emissions data, calculate the annual CO2 
mass emissions for the purposes of this part as follows:
    (A) Use the hourly heat input data from appendix D to part 75 of 
this chapter, together with Equation G-4 in appendix G to part 75 of 
this chapter to determine the hourly CO2 mass emission rates, 
in units of tons/hr;
    (B) Use Equations F-12 and F-13 in appendix F to part 75 of this 
chapter to calculate the quarterly and cumulative annual CO2 
mass emissions, respectively, in units of short tons; and
    (C) Divide the cumulative annual CO2 mass emissions value 
by 1.1023 to convert it to metric tons.
    (ii) For a unit that combusts only natural gas and/or fuel oil, is 
not subject to subpart D of this part, monitors and reports heat input 
data year-round according to Sec. 75.19 of this chapter but is not 
required by the applicable part 75 program to report CO2 mass 
emissions data, calculate the annual CO2 mass emissions for 
the purposes of this part as follows:
    (A) Calculate the hourly CO2 mass emissions, in units of 
short tons, using Equation LM-11 in Sec. 75.19(c)(4)(iii) of this 
chapter.
    (B) Sum the hourly CO2 mass emissions values over the 
entire reporting year to obtain the cumulative annual CO2 
mass emissions, in units of short tons.
    (C) Divide the cumulative annual CO2 mass emissions value 
by 1.1023 to convert it to metric tons.
    (iii) For a unit that is not subject to subpart D of this part, uses 
flow rate and CO2 (or O2) CEMS to report heat 
input data year-round according to part 75 of this chapter, but is not 
required by the applicable part 75 program to report CO2 mass 
emissions data, calculate the annual CO2 mass emissions as 
follows:
    (A) Use Equation F-11 or F-2 (as applicable) in appendix F to part 
75 of this chapter to calculate the hourly CO2 mass emission 
rates from the CEMS data. If an O2 monitor is used, convert 
the hourly average O2 readings to CO2 using 
Equation F-14a or F-14b in appendix F to part 75 of this chapter (as 
applicable), before applying Equation F-11 or F-2.
    (B) Use Equations F-12 and F-13 in appendix F to part 75 of this 
chapter to calculate the quarterly and cumulative annual CO2 
mass emissions, respectively, in units of short tons.
    (C) Divide the cumulative annual CO2 mass emissions value 
by 1.1023 to convert it to metric tons.
    (iv) For units that qualify to use the alternative CO2 
emissions calculation methods in paragraphs (a)(5)(i) through 
(a)(5)(iii) of this section, if both biomass and fossil fuel are 
combusted during the year, separate calculation and reporting of the 
biogenic CO2 mass emissions (as described in paragraph (e) of 
this section) is optional, only for the 2010 reporting year, as provided 
in Sec. 98.3(c)(12).
    (b) Use of the four tiers. Use of the four tiers of CO2 
emissions calculation methodologies described in paragraph

[[Page 622]]

    (iv) Shall be used when specified in another applicable subpart of 
this part, regardless of unit size.
    (4) The Tier 4 Calculation Methodology:

specified in paragraphs (b)(4)(ii)(A) through (b)(4)(ii)(F) of this 
section:
    (A) The unit has a maximum rated heat input capacity greater than 
250 mmBtu/hr, or if the unit combusts municipal solid waste and has a

required, either by an applicable Federal or State regulation or by the 
unit's operating permit, to undergo periodic quality assurance testing 
in accordance with either appendix B to part 75 of this chapter, 
appendix F to part 60 of this chapter, or an applicable State continuous 
monitoring program.
    (iii) Shall be used for a unit with a maximum rated heat input 
capacity of 250 mmBtu/hr or less and for a unit that combusts municipal 
solid waste with a maximum rated input capacity of 600 tons of MSW per 
day or less, if the unit meets all of the following three conditions:
    (A) The unit has both a stack gas volumetric flow rate monitor and a 
CO2 concentration monitor.
    (B) The unit meets the conditions specified in paragraphs 
(b)(4)(ii)(B) through (b)(4)(ii)(D) of this section.
    (C) The CO2 and stack gas volumetric flow rate monitors

(b)(4)(ii)(F) of this section.
    (iv) May apply to common stack or duct configurations where:
    (A) The combined effluent gas streams from two or more stationary 
fuel combustion units are vented through a monitored common stack or 
duct. In this case, Tier 4 shall be used if all of the conditions in 
paragraph (b)(4)(iv)(A)(1) of this section or if the conditions in 
paragraph (b)(4)(iv)(A)(2) of this section are met.
    (1) At least one of the units meets the requirements of paragraphs 
(b)(4)(ii)(A) through (b)(4)(ii)(C) of this section, and the CEMS 
installed at the common stack (or duct) meet the requirements of 
paragraphs (b)(4)(ii)(D) through (b)(4)(ii)(F) of this section.
    (2) At least one of the units and the monitors installed at the 
common stack or duct meet the requirements of paragraph (b)(4)(iii) of 
this section.
    (B) The combined effluent gas streams from a process or 
manufacturing unit and a stationary fuel combustion unit are vented 
through a monitored common stack or duct. In this case, Tier 4 shall be 
used if the combustion unit and the monitors installed at the common

(b)(4)(iv)(A)(1), or (b)(4)(iv)(A)(2) of this section.
    (C) The combined effluent gas streams from two or more manufacturing 
or process units are vented through a common stack or duct. In this 
case, if any of the units is required by an applicable subpart of this 
part to use Tier 4, the CO2 mass emissions may be monitored 
at each individual unit, or the combined CO2 mass emissions 
may be monitored at the common stack or duct. However, if it is not 
feasible to monitor the individual units, the combined CO2 
mass emissions shall be monitored at the common stack or duct.

[[Page 624]]

    (5) The Tier 4 Calculation Methodology shall be used:
    (i) Starting on January 1, 2010, for a unit that is required to 
report CO2 mass emissions beginning on that date, if all of 
the monitors needed to measure CO2 mass emissions have been 
installed and certified by that date.
    (ii) No later than January 1, 2011, for a unit that is required to 
report CO2 mass emissions beginning on January 1, 2010, if 
all of the monitors needed to measure CO2 mass emissions have 
not been installed and certified by January 1, 2010. In this case, you 
may use Tier 2 or Tier 3 to report GHG emissions for 2010. However, if 
the required CEMS are certified some time in 2010, you need not wait 
until January 1, 2011 to begin using Tier 4. Rather, you may switch from 
Tier 2 or Tier 3 to Tier 4 as soon as CEMS certification testing is 
successfully completed. If this reporting option is chosen, you must 
document the change in CO2 calculation methodology in the 
Monitoring Plan required under Sec. 98.3(g)(5) and in the GHG emissions 
report under Sec. 98.3(c). Data recorded by the CEMS during a 
certification test period in 2010 may be used for reporting under this 
part, provided that the following two conditions are met:
    (A) The certification tests are passed in sequence, with no test 
failures.
    (B) No unscheduled maintenance or repair of the CEMS is performed 
during the certification test period.
    (iii) No later than 180 days following the date on which a change is 
made that triggers Tier 4 applicability under paragraph (b)(4)(ii) or 
(b)(4)(iii) of this section (e.g., a change in the primary fuel, manner 
of unit operation, or installed continuous monitoring equipment).
    (6) You may elect to use any applicable higher tier for one or more 
of the fuels combusted in a unit. For example, if a 100 mmBtu/hr unit 
combusts natural gas and distillate fuel oil, you may elect to use Tier 
1 for natural gas and Tier 3 for the fuel oil, even though Tier 1 could 
have been used for both fuels. However, for units that use either the 
Tier 4 or the alternative calculation methodology specified in paragraph 
(a)(5)(iii) of this section, CO2 emissions from the 
combustion of all fuels shall be based solely on CEMS measurements.
    (c) Calculation of CH4 and N2O emissions from stationary combustion 
sources. You must calculate annual CH4 and N2O 
mass emissions only for units that are required to report CO2 
emissions using the calculation methodologies of this subpart and for 
only those fuels that are listed in Table C-2 of this subpart.
    (1) Use Equation C-8 of this section to estimate CH4 and 
N2O emissions for any fuels for which you use the Tier 1 or 
Tier 3 calculation methodologies for CO2, except when natural 
gas usage in units of therms or mmBtu is obtained from gas billing 
records. In that case, use Equation C-8a in paragraph (c)(1)(i) of this 
section or Equation C-8b in paragraph (c)(1)(ii) of this section (as 
applicable). For Equation C-8, use the same values for fuel consumption 
that you use for the Tier 1 or Tier 3 calculation.

    (4) Use Equation C-10 of this section for: units subject to subpart 
D of this part; units that qualify for and elect to use the alternative 
CO2 mass emissions calculation methodologies described in 
paragraph (a)(5) of this section; and units that use the Tier 4 
Calculation Methodology.
[GRAPHIC] [TIFF OMITTED] TR30OC09.016

Where:

CH4 or N2O = Annual CH4 or 
          N2O emissions from the combustion of a particular 
          type of fuel (metric tons).
(HI)A = Cumulative annual heat input from combustion of the 
          fuel (mmBtu).
EF = Fuel-specific emission factor for CH4 or N2O, 
          from Table C-2 of this section (kg CH4 or 
          N2O per mmBtu).
0.001 = Conversion factor from kg to metric tons.

    (i) If only one type of fuel listed in Table C-2 of this subpart is 
combusted during the reporting year, substitute the cumulative annual 
heat input from combustion of the fuel into Equation C-10 of this 
section to calculate the annual CH4 or N2O 
emissions. For units in the Acid Rain Program and units that report heat 
input data to EPA year-round according to part 75 of this chapter, 
obtain the cumulative annual heat input directly from the electronic 
data reports required under Sec. 75.64 of this chapter. For Tier 4 
units, use the best available information, as described in paragraph 
(c)(4)(ii)(C) of this section, to estimate the cumulative annual heat 
input (HI)A.
    (ii) If more than one type of fuel listed in Table C-2 of this 
subpart is combusted during the reporting year, use Equation C-10 of 
this section separately for each type of fuel, except as provided in 
paragraph (c)(4)(ii)(B) of this section. Determine the appropriate 
values of (HI)A as follows:
    (A) For units in the Acid Rain Program and other units that report 
heat input data to EPA year-round according to part 75 of this chapter, 
obtain (HI)A for each type of fuel from the electronic data 
reports required under Sec. 75.64 of this chapter, except as otherwise 
provided in paragraphs (c)(4)(ii)(B) and (c)(4)(ii)(D) of this section.
    (B) For a unit that uses CEMS to monitor hourly heat input according 
to part 75 of this chapter, the value of (HI)A obtained from 
the electronic data reports under Sec. 75.64 of this chapter may be 
attributed exclusively to the fuel with the highest F-factor, when the 
reporting option in 3.3.6.5 of appendix F to part 75 of this chapter is 
selected and implemented.
    (C) For Tier 4 units, use the best available information (e.g., fuel 
feed rate measurements, fuel heating values, engineering analysis) to 
estimate the value of (HI)A for each type of fuel. 
Instrumentation used to make these estimates is not subject to the 
calibration requirements of Sec. 98.3(i) or to the QA requirements of 
Sec. 98.34.
    (D) Units in the Acid Rain Program and other units that report heat 
input data to EPA year-round according to part 75 of this chapter may 
use the best available information described in paragraph (c)(4)(ii)(C) 
of this section, to estimate (HI)A for each fuel type, 
whenever fuel-specific heat input values cannot be directly obtained 
from the electronic data reports under Sec. 75.64 of this chapter.
    (5) When multiple fuels are combusted during the reporting year, sum 
the fuel-specific results from Equations C-8, C-8a, C-8b, C-9a, C-9b, or 
C-10 of this section (as applicable) to obtain the total annual 
CH4 and N2O emissions, in metric tons.
    (6) Calculate the annual CH4 and N2O mass 
emissions from the combustion of blended fuels as follows:
    (i) If the mass or volume of each component fuel in the blend is 
measured before the fuels are mixed and combusted, calculate and report 
CH4 and N2O emissions separately for each 
component fuel, using the applicable procedures in this paragraph (c).
    (ii) If the mass or volume of each component fuel in the blend is 
not measured before the fuels are mixed and combusted, a reasonable 
estimate of the percentage composition of the

[[Page 627]]

blend, based on best available information, is required. Perform the 
following calculations for each component fuel ``i'' that is listed in 
Table C-2:
    (A) Multiply (% Fuel)i, the estimated mass or volume 
percentage (decimal fraction) of component fuel ``i'', by the total 
annual mass or volume of the blended fuel combusted during the reporting 
year, to obtain an estimate of the annual consumption of component 
``i'';
    (B) Multiply the result from paragraph (c)(6)(ii)(A) of this section 
by the HHV of the fuel (default value or, if available, the measured 
annual average value), to obtain an estimate of the annual heat input 
from component ``i'';
    (C) Calculate the annual CH4 and N2O emissions 
from component ``i'', using Equation C-8, C-8a, C-8b, C-9a, or C-10 of 
this section, as applicable;
    (D) Sum the annual CH4 emissions across all component 
fuels to obtain the annual CH4 emissions for the blend. 
Similarly sum the annual N2O emissions across all component 
fuels to obtain the annual N2O emissions for the blend. 
Report these annual emissions totals.
    (d) Calculation of CO2 from sorbent. (1) When a unit is a fluidized 
bed boiler, is equipped with a wet flue gas desulfurization system, or 
uses other acid gas emission controls with sorbent injection to remove 
acid gases, if the chemical reaction between the acid gas and the 
sorbent produces CO2 emissions, use Equation C-11 of this 
section to calculate the CO2 emissions from the sorbent, 
except when those CO2 emissions are monitored by CEMS. When a 
sorbent other than CaCO3 is used, determine site-specific 
values of R and MWS.
[GRAPHIC] [TIFF OMITTED] TR30OC09.017

Where:

CO2 = CO2 emitted from sorbent for the reporting 
          year (metric tons).
S = Limestone or other sorbent used in the reporting year, from company 
          records (short tons).
R = The number of moles of CO2 released upon capture of one 
          mole of the acid gas species being removed (R = 1.00 when the 
          sorbent is CaCO3 and the targeted acid gas species 
          is SO2).
MWCO2 = Molecular weight of carbon dioxide (44).
MWS = Molecular weight of sorbent (100 if calcium carbonate).
0.91 = Conversion factor from short tons to metric tons.

    (2) The total annual CO2 mass emissions reported for the 
unit shall include the CO2 emissions from the combustion 
process and the CO2 emissions from the sorbent.
    (e) Biogenic CO2 emissions from combustion of biomass with other 
fuels. Use the applicable procedures of this paragraph (e) to estimate 
biogenic CO2 emissions from units that combust a combination 
of biomass and fossil fuels (i.e., either co-fired or blended fuels). 
Separate reporting of biogenic CO2 emissions from the 
combined combustion of biomass and fossil fuels is required for those 
biomass fuels listed in Table C-1 of this section and for municipal 
solid waste. In addition, when a biomass fuel that is not listed in 
Table C-1 is combusted in a unit that has a maximum rated heat input 
greater than 250 mmBtu/hr, if the biomass fuel accounts for 10% or more 
of the annual heat input to the unit, and if the unit does not use CEMS 
to quantify its annual CO2 mass emissions, then, pursuant to 
Sec. 98.33(b)(3)(iii), Tier 3 must be used to determine the carbon 
content of the biomass fuel and to calculate the biogenic CO2 
emissions from combustion of the fuel. Notwithstanding these 
requirements, in accordance with Sec. 98.3(c)(12), separate reporting 
of biogenic CO2 emissions is optional for the 2010 reporting 
year for units subject to subpart D of this part and for units that use 
the CO2 mass emissions calculation methodologies in part 75 
of this chapter, pursuant to paragraph (a)(5) of this section. However, 
if the owner or operator opts to

[[Page 628]]

report biogenic CO2 emissions separately for these units, the 
appropriate method(s) in this paragraph (e) shall be used. Separate 
reporting of biogenic CO2 emissions from the combustion of 
tires is also optional, but may be reported by following the provisions 
of paragraph (e)(3) of this section.
    (1) You may use Equation C-1 of this subpart to calculate the annual 
CO2 mass emissions from the combustion of the biomass fuels 
listed in Table C-1 of this subpart (except MSW and tires), in a unit of 
any size, including units equipped with a CO2 CEMS, except 
when the use of Tier 2 is required as specified in paragraph (b)(1)(iv) 
of this section. Determine the quantity of biomass combusted using one 
of the following procedures in this paragraph (e)(1), as appropriate, 
and document the selected procedures in the Monitoring Plan under Sec. 
98.3(g):
    (i) Company records.
    (ii) The procedures in paragraph (e)(4) of this section.
    (iii) The best available information for premixed fuels that contain 
biomass and fossil fuels (e.g., liquid fuel mixtures containing 
biodiesel).
    (2) You may use the procedures of this paragraph if the following 
three conditions are met: First, a CO2 CEMS (or a surrogate 
O2 monitor) and a stack gas flow rate monitor are used to 
determine the annual CO2 mass emissions (either according to 
part 75 of this chapter, the Tier 4 Calculation Methodology, or the 
alternative calculation methodology specified in paragraph (a)(5)(iii) 
of this section); second, neither MSW nor tires is combusted in the unit 
during the reporting year; and third, the CO2 emissions 
consist solely of combustion products (i.e., no process or sorbent 
emissions included).
    (i) For each operating hour, use Equation C-12 of this section to 
determine the volume of CO2 emitted.
[GRAPHIC] [TIFF OMITTED] TR30OC09.018

Where:

VCO2h = Hourly volume of CO2 emitted (scf).
(%CO2)h = Hourly average CO2 
          concentration, measured by the CO2 concentration 
          monitor, or, if applicable, calculated from the hourly average 
          O2 concentration (%CO2).
Qh = Hourly average stack gas volumetric flow rate, measured 
          by the stack gas volumetric flow rate monitor (scfh).
th = Source operating time (decimal fraction of the hour 
          during which the source combusts fuel, i.e., 1.0 for a full 
          operating hour, 0.5 for 30 minutes of operation, etc.).
100 = Conversion factor from percent to a decimal fraction.

    (ii) Sum all of the hourly VCO2h values for the reporting 
year, to obtain Vtotal, the total annual volume of 
CO2 emitted.
    (iii) Calculate the annual volume of CO2 emitted from 
fossil fuel combustion using Equation C-13 of this section. If two or 
more types of fossil fuel are combusted during the year, perform a 
separate calculation with Equation C-13 of this section for each fuel 
and sum the results.
[GRAPHIC] [TIFF OMITTED] TR30OC09.019

Where:

Vff = Annual volume of CO2 emitted from combustion 
          of a particular fossil fuel (scf).
Fuel = Total quantity of the fossil fuel combusted in the reporting 
          year, from company records, as defined in Sec. 98.6 (lb for 
          solid fuel, gallons for liquid fuel, and scf for gaseous 
          fuel).
Fc = Fuel-specific carbon based F-factor, either a default 
          value from Table 1 in section 3.3.5 of appendix F to part 75 
          of this chapter, or a site-specific value determined under 
          section 3.3.6 of appendix F to part 75 (scf CO2/
          mmBtu).
HHV = High heat value of the fossil fuel, from fuel sampling and 
          analysis (annual average value in Btu/lb for solid fuel, Btu/
          gal for liquid fuel and Btu/scf for gaseous fuel, sampled as 
          specified (e.g., monthly, quarterly, semi-annually, or by lot) 
          in Sec. 98.34(a)(2)). The average HHV

[[Page 629]]

          shall be calculated according to the requirements of paragraph 
          (a)(2)(ii) of this section.
10\6\ = Conversion factor, Btu per mmBtu.

    (iv) Subtract Vff from Vtotal to obtain 
Vbio, the annual volume of CO2 from the combustion 
of biomass.
    (v) Calculate the biogenic percentage of the annual CO2 
emissions,expressed as a decimal fraction, using Equation C-14 of this 
section:
[GRAPHIC] [TIFF OMITTED] TR30OC09.020

    (vi) Calculate the annual biogenic CO2 mass emissions, in 
metric tons, by multiplying the results obtained from Equation C-14 of 
this section by the annual CO2 mass emissions in metric tons, 
as determined:
    (A) Under paragraph (a)(4)(vi) of this section, for units using the 
Tier 4 Calculation Methodology.
    (B) Under paragraph (a)(5)(iii)(B) of this section, for units using 
the alternative calculation methodology specified in paragraph 
(a)(5)(iii).
    (C) From the electronic data report required under Sec. 75.64 of 
this chapter, for units in the Acid Rain Program and other units using 
CEMS to monitor and report CO2 mass emissions according to 
part 75 of this chapter. However, before calculating the annual biogenic 
CO2 mass emissions, multiply the cumulative annual 
CO2 mass emissions by 0.91 to convert from short tons to 
metric tons.
    (3) You must use the procedures in paragraphs (e)(3)(i) through 
(e)(3)(iii) of this section to determine the annual biogenic 
CO2 emissions from the combustion of MSW, except as otherwise 
provided in paragraph (e)(3)(iv) of this section. These procedures also 
may be used for any unit that co-fires biomass and fossil fuels, 
including units equipped with a CO2 CEMS, and units for which 
optional separate reporting of biogenic CO2 emissions from 
the combustion of tires is selected.
    (i) Use an applicable CO2 emissions calculation method in 
this section to quantify the total annual CO2 mass emissions 
from the unit.
    (ii) Determine the relative proportions of biogenic and non-biogenic 
CO2 emissions in the flue gas on a quarterly basis using the 
method specified in Sec. 98.34(d) (for units that combust MSW as the 
primary fuel or as the only fuel with a biogenic component) or in Sec. 
98.34(e) (for other units, including units that combust tires).
    (iii) Determine the annual biogenic CO2 mass emissions 
from the unit by multiplying the total annual CO2 mass 
emissions by the annual average biogenic decimal fraction obtained from 
Sec. 98.34(d) or Sec. 98.34(e), as applicable.
    (iv) If the combustion of MSW and/or tires provides no more than 10 
percent of the annual heat input to a unit, or if a small, batch 
incinerator combusts no more than 1,000 tons per year of MSW, you may 
estimate the annual biogenic CO2 emissions as follows, in 
lieu of following the procedures in paragraphs (e)(3)(i) through 
(e)(3)(iii) of this section:
    (A) Calculate the total annual CO2 emissions from 
combustion of MSW and/or tires in the unit, using the Tier 1 calculation 
methodology in paragraph (a)(1) of this section.
    (B) Multiply the result from paragraph (e)(3)(iv)(A) of this section 
by the appropriate default factor to determine the annual biogenic 
CO2 emissions, in metric tons. For MSW, use a default factor 
of 0.60 and for tires, use a default factor of 0.20.
    (4) If Equation C-1 or Equation C-2a of this section is selected to 
calculate the annual biogenic mass emissions for wood, wood waste, or 
other solid biomass-derived fuel, Equation C-15 of this section may be 
used to quantify biogenic fuel consumption, provided that all of the 
required input parameters are accurately quantified. Similar equations 
and calculation methodologies based on steam generation and boiler 
efficiency may be used, provided that they are documented in the GHG 
Monitoring Plan required by Sec. 98.3(g)(5).

Where:

(Fuel)p = Quantity of biomass consumed during the measurement 
          period ``p'' (tons/year or tons/month, as applicable).
H = Average enthalpy of the boiler steam for the measurement period 
          (Btu/lb).
S = Total boiler steam production for the measurement period (lb/month 
          or lb/year, as applicable).
(HI)nb = Heat input from co-fired fossil fuels and non-
          biomass-derived fuels for the measurement period, based on 
          company records of fuel usage and default or measured HHV 
          values (Btu/month or Btu/year, as applicable).

    (5) For units subject to subpart D of this part and for units that 
use the methods in part 75 of this chapter to quantify CO2 
mass emissions in accordance with paragraph (a)(5) of this section, you 
may calculate biogenic CO2 emissions from the combustion of 
biomass fuels listed in Table C-1 of this subpart using Equation C-15a. 
This equation may not be used to calculate biogenic CO2 
emissions from the combustion of tires or MSW; the methods described in 
paragraph (e)(3) of this section must be used for those fuels. Whenever 
(HI)A, the annual heat input from combustion of biomass fuel 
in Equation C-15a, cannot be determined solely from the information in 
the electronic emissions reports under Sec. 75.64 of this chapter 
(e.g., in cases where a unit uses CEMS in combination with multiple F-
factors, a worst-case F-factor, or a prorated F-factor to report heat 
input rather than reporting heat input based on fuel type), use the best 
available information (as described in Sec. Sec. 98.33(c)(4)(ii)(C) and 
(c)(4)(ii)(D)) to determine (HI)A.

    CO2 = 0.001 * (HI)A * EF (Eq. C-15a)

where:

CO2 = Annual CO2 mass emissions from the 
          combustion of a particular type of biomass fuel listed in 
          Table C-1 (metric tons)
(HI)A = Annual heat input from the biomass fuel, obtained, 
          where feasible, from the electronic emissions reports required 
          under Sec. 75.64 of this chapter. Where this is not feasible 
          use best available information, as described in Sec. Sec. 
          98.33(c)(4)(ii)(C) and (c)(4)(ii)(D) (mmBtu)
EF = CO2 emission factor for the biomass fuel, from Table C-1 
          (kg CO2/mmBtu)

Sec. 98.34  Monitoring and QA/QC requirements.

    The CO2 mass emissions data for stationary fuel 
combustion sources shall be monitored as follows:
    (a) For the Tier 2 Calculation Methodology:
    (1) All fuel samples shall be taken at a location in the fuel 
handling system that provides a sample representative of the fuel 
combusted. The fuel sampling and analysis may be performed by either the 
owner or operator or the supplier of the fuel.
    (2) The minimum required frequency of the HHV sampling and analysis 
for each type of fuel or fuel mixture (blend) is specified in this 
paragraph. When the specified frequency for a particular fuel or blend 
is based on a specified time period (e.g., week, month, quarter, or 
half-year), fuel sampling and analysis is required only for those time 
periods in which the fuel or blend is combusted. The owner or operator 
may perform fuel sampling and analysis more often than the minimum 
required frequency, in order to obtain a more representative annual 
average HHV.
    (i) For natural gas, semiannual sampling and analysis is required 
(i.e., twice in a calendar year, with consecutive samples taken at least 
four months apart).
    (ii) For coal and fuel oil, and for any other solid or liquid fuel 
that is delivered in lots, analysis of at least one representative 
sample from each fuel

[[Page 631]]

lot is required. For fuel oil, as an alternative to sampling each fuel 
lot, a sample may be taken upon each addition of oil to the unit's 
storage tank. Flow proportional sampling, continuous drip sampling, or 
daily manual oil sampling may also be used, in lieu of sampling each 
fuel lot. If the daily manual oil sampling option is selected, sampling 
from a particular tank is required only on days when oil from the tank 
is combusted by the unit (or units) served by the tank. If you elect to 
sample from the storage tank upon each addition of oil to the tank, you 
must take at least one sample from each tank that is currently in 
service and whenever oil is added to the tank, for as long as the tank 
remains in service. You need not take any samples from a storage tank 
while it is out of service. Rather, take a sample when the tank is 
brought into service and whenever oil is added to the tank, for as long 
as the tank remains in service. If multiple additions of oil are made to 
a particular in-service tank on a given day (e.g., from multiple 
deliveries), one sample taken after the final addition of oil is 
sufficient. For the purposes of this section, a fuel lot is defined as a 
shipment or delivery of a single type of fuel (e.g., ship load, barge 
load, group of trucks, group of railroad cars, oil delivery via pipeline 
from a tank farm, etc.). However, if multiple deliveries of a particular 
type of fuel are received from the same supply source in a given 
calendar month, the deliveries for that month may be considered, 
collectively, to comprise a fuel lot, requiring only one representative 
sample, subject to the following conditions:
    (A) For coal, the ``type'' of fuel means the rank of the coal (i.e., 
anthracite, bituminous, sub-bituminous, or lignite). For fuel oil, the 
``type'' of fuel means the grade number or classification of the oil 
(e.g., No. 1 oil, No. 2 oil, kerosene, Jet A fuel, etc.).
    (B) The owner or operator shall document in the monitoring plan 
under Sec. 98.3(g)(5) how the monthly sampling of each type of fuel is 
performed.
    (iii) For liquid fuels other than fuel oil, and for gaseous fuels 
other than natural gas (including biogas), sampling and analysis is 
required at least once per calendar quarter. To the extent practicable, 
consecutive quarterly samples shall be taken at least 30 days apart.
    (iv) For other solid fuels (except MSW), weekly sampling is required 
to obtain composite samples, which are then analyzed monthly.
    (v) For fuel blends that are received already mixed, or that are 
mixed on-site without measuring the exact amount of each component, as 
described in paragraph (a)(3)(ii) of this section, determine the HHV of 
the blend as follows. For blends of solid fuels (except MSW), weekly 
sampling is required to obtain composite samples, which are analyzed 
monthly. For blends of liquid or gaseous fuels, sampling and analysis is 
required at least once per calendar quarter. More frequent sampling is 
recommended if the composition of the blend varies significantly during 
the year.
    (3) Special considerations for blending of fuels. In situations 
where different types of fuel listed in Table C-1 of this subpart (for 
example, different ranks of coal or different grades of fuel oil) are in 
the same state of matter (i.e., solid, liquid, or gas), and are blended 
prior to combustion, use the following procedures to determine the 
appropriate CO2 emission factor and HHV for the blend.
    (i) If the fuels to be blended are received separately, and if the 
quantity (mass or volume) of each fuel is measured before the fuels are 
mixed and combusted, then, for each component of the blend, calculate 
the CO2 mass emissions separately. Substitute into Equation 
C-2a of this subpart the total measured mass or volume of the component 
fuel (from company records), together with the appropriate default 
CO2 emission factor from Table C-1, and the annual average 
HHV, calculated according to Sec. 98.33(a)(2)(ii). In this case, the 
fact that the fuels are blended prior to combustion is of no 
consequence.
    (ii) If the fuel is received as a blend (i.e., already mixed) or if 
the components are mixed on site without precisely measuring the mass or 
volume of each one individually, a reasonable estimate of the relative 
proportions of the components of the blend must be

[[Page 632]]

made, using the best available information (e.g., the approximate annual 
average mass or volume percentage of each fuel, based on the typical or 
expected range of values). Determine the appropriate CO2 
emission factor and HHV for use in Equation C-2a of this subpart, as 
follows:
    (A) Consider the blend to be the ``fuel type,'' measure its HHV at 
the frequency prescribed in paragraph (a)(2)(v) of this section, and 
determine the annual average HHV value for the blend according to Sec. 
98.33(a)(2)(ii).
    (B) Calculate a heat-weighted CO2 emission factor, 
(EF)B, for the blend, using Equation C-16 of this section. 
The heat-weighting in Equation C-16 is provided by the default HHVs 
(from Table C-1) and the estimated mass or volume percentages of the 
components of the blend.
    (C) Substitute into Equation C-2a of this subpart, the annual 
average HHV for the blend (from paragraph (a)(3)(ii)(A) of this section) 
and the calculated value of (EF)B, along with the total mass 
or volume of the blend combusted during the reporting year, to determine 
the annual CO2 mass emissions from combustion of the blend.
[GRAPHIC] [TIFF OMITTED] TR17DE10.003

where:

(EF)B = Heat-weighted CO2 emission factor for the 
          blend (kg CO2/mmBtu)
(HHV)i = Default high heat value for fuel ``i'' in the blend, 
          from Table C-1 (mmBtu per mass or volume)
(%Fuel)i = Estimated mass or volume percentage of fuel ``i'' 
          (mass % or volume %, as applicable, expressed as a decimal 
          fraction; e.g., 25% = 0.25)
(EF)i = Default CO2 emission factor for fuel ``i'' 
          from Table C-1 (mmBtu per mass or volume)
(HHV)B = Annual average high heat value for the blend, 
          calculated according to Sec. 98.33(a)(2)(ii) (mmBtu per mass 
          or volume)

    (iii) Note that for the case described in paragraph (a)(3)(ii) of 
this section, if measured HHV values for the individual fuels in the 
blend or for the blend itself are not routinely received at the minimum 
frequency prescribed in paragraph (a)(2) of this section (or at a 
greater frequency), and if the unit qualifies to use Tier 1, calculate 
(HHV)B*, the heat-weighted default HHV for the blend, using 
Equation C-17 of this section. Then, use Equation C-16 of this section, 
replacing the term (HHV)B with (HHV)B* in the 
denominator, to determine the heat-weighted CO2 emission 
factor for the blend. Finally, substitute into Equation C-1 of this 
subpart, the calculated values of (HHV)B* and 
(EF)B, along with the total mass or volume of the blend 
combusted during the reporting year, to determine the annual 
CO2 mass emissions from combustion of the blend.
[GRAPHIC] [TIFF OMITTED] TR17DE10.004

where:

(HHV)B* = Heat-weighted default high heat value for the blend 
          (mmBtu per mass or Volume)
(HHV)i = Default high heat value for fuel ``i'' in the blend, 
          from Table C-1 (mmBtu per mass or volume)
(%Fuel)i = Estimated mass or volume percentage of fuel ``i'' 
          in the blend (mass %

[[Page 633]]

          or volume %, as applicable, expressed as a decimal fraction)

    (iv) If the fuel blend described in paragraph (a)(3)(ii) of this 
section consists of a mixture of fuel(s) listed in Table C-1 of this 
subpart and one or more fuels not listed in Table C-1, calculate 
CO2 and other GHG emissions only for the Table C-1 fuel(s), 
using the best available estimate of the mass or volume percentage(s) of 
the Table C-1 fuel(s) in the blend. In this case, Tier 1 shall be used, 
with the following modifications to Equations C-17 and C-1, to account 
for the fact that not all of the fuels in the blend are listed in Table 
C-1:
    (A) In Equation C-17, apply the term (Fuel)i only to the 
Table C-1 fuels. For each Table C-1 fuel, (Fuel)i will be the 
estimated mass or volume percentage of the fuel in the blend, divided by 
the sum of the mass or volume percentages of the Table C-1 fuels. For 
example, suppose that a blend consists of two Table C-1 fuels (``A'' and 
``B'') and one fuel type (``C'') not listed in the Table, and that the 
volume percentages of fuels A, B, and C in the blend, expressed as 
decimal fractions, are, respectively, 0.50, 0.30, and 0.20. The term 
(Fuel)i in Equation C-17 for fuel A will be 0.50/(0.50 + 
0.30) = 0.625, and for fuel B, (Fuel)i will be 0.30/(0.50 + 
0.30) = 0.375.
    (B) In Equation C-1, the term ``Fuel'' will be equal to the total 
mass or volume of the blended fuel combusted during the year multiplied 
by the sum of the mass or volume percentages of the Table C-1 fuels in 
the blend. For the example in paragraph (a)(3)(iv)(A) of this section, 
``Fuel'' = (Annual volume of the blend combusted)(0.80).
    (4) If, for a particular type of fuel, HHV sampling and analysis is 
performed more often than the minimum frequency specified in paragraph 
(a)(2) of this section, the results of all valid fuel analyses shall be 
used in the GHG emission calculations.
    (5) If, for a particular type of fuel, valid HHV values are obtained 
at less than the minimum frequency specifed in paragraph (a)(2) of this 
section, appropriate substitute data values shall be used in the 
emissions calculations, in accordance with missing data procedures of 
Sec. 98.35.
    (6) You must use one of the following appropriate fuel sampling and 
analysis methods. The HHV may be calculated using chromatographic 
analysis together with standard heating values of the fuel constituents, 
provided that the gas chromatograph is operated, maintained, and 
calibrated according to the manufacturer's instructions. Alternatively, 
you may use a method published by a consensus-based standards 
organization if such a method exists, or you may use industry standard 
practice to determine the high heat values. Consensus-based standards 
organizations include, but are not limited to, the following: ASTM

and recordkeeping requirements of Sec. Sec. 98.3(g)(5)(i)(C), (g)(6), 
and (g)(7), provided that the fuel supplier and the unit combusting the 
fuel do not have any common owners and are not owned by subsidiaries or 
affiliates of the same company. Meters used exclusively to measure the 
flow rates of fuels that are only used for unit startup are also 
exempted from the initial and ongoing calibration requirements of this 
paragraph.
    (iv) For the initial calibration of an orifice, nozzle, or venturi 
meter; in-situ calibration of the transmitters is sufficient. A primary 
element inspection (PEI) shall be performed at least once every three 
years.
    (v) For the continuously-operating units and processes described in 
Sec. 98.3(i)(6), the required flow meter recalibrations and, if 
necessary, the PEIs may be postponed until the next scheduled 
maintenance outage.
    (vi) If a mixture of liquid or gaseous fuels is transported by a 
common pipe, you may either separately meter each of the fuels prior to 
mixing, using flow meters calibrated according to Sec. 98.3(i), or 
consider the fuel mixture to be the ``fuel type'' and meter the mixed 
fuel, using a flow meter calibrated according to Sec. 98.3(i).
    (2) Oil tank drop measurements (if used to determine liquid fuel use 
volume) shall be performed according to any an appropriate method 
published by a consensus-based standards organization (e.g., the 
American Petroleum Institute).
    (3) The carbon content and, if applicable, molecular weight of the 
fuels shall be determined according to the procedures in this paragraph 
(b)(3).
    (i) All fuel samples shall be taken at a location in the fuel 
handling system that provides a sample representative of the fuel 
combusted. The fuel sampling and analysis may be performed by either the 
owner or operator or by the supplier of the fuel.
    (ii) For each type of fuel, the minimum required frequency for 
collecting and analyzing samples for carbon content and (if applicable) 
molecular weight is specified in this paragraph. When the sampling 
frequency is based on a specified time period (e.g., week, month, 
quarter, or half-year), fuel sampling and analysis is required for only 
those time periods in which the fuel is combusted.
    (A) For natural gas, semiannual sampling and analysis is required 
(i.e., twice in a calendar year, with consecutive samples taken at least 
four months apart).
    (B) For coal and fuel oil and for any other solid or liquid fuel 
that is delivered in lots, analysis of at least one representative 
sample from each fuel lot is required. For fuel oil, as an alternative 
to sampling each fuel lot, a sample may be taken upon each addition of 
oil to the storage tank. Flow proportional sampling, continuous drip 
sampling, or daily manual oil sampling

[[Page 635]]

may also be used, in lieu of sampling each fuel lot. If the daily manual 
oil sampling option is selected, sampling from a particular tank is 
required only on days when oil from the tank is combusted by the unit 
(or units) served by the tank. If you elect to sample from the storage 
tank upon each addition of oil to the tank, you must take at least one 
sample from each tank that is currently in service and whenever oil is 
added to the tank, for as long as the tank remains in service. You need 
not take any samples from a storage tank while it is out of service. 
Rather, take a sample when the tank is brought into service and whenever 
oil is added to the tank, for as long as the tank remains in service. If 
multiple additions of oil are made to a particular in service tank on a 
given day (e.g., from multiple deliveries), one sample taken after the 
final addition of oil is sufficient. For the purposes of this section, a 
fuel lot is defined as a shipment or delivery of a single type of fuel 
(e.g., ship load, barge load, group of trucks, group of railroad cars, 
oil delivery via pipeline from a tank farm, etc.). However, if multiple 
deliveries of a particular type of fuel are received from the same 
supply source in a given calendar month, the deliveries for that month 
may be considered, collectively, to comprise a fuel lot, requiring only 
one representative sample, subject to the following conditions:
    (1) For coal, the ``type'' of fuel means the rank of the coal (i.e., 
anthracite, bituminous, sub-bituminous, or lignite). For fuel oil, the 
``type'' of fuel means the grade number or classification of the oil 
(e.g., No. 1 oil, No. 2 oil, kerosene, Jet A fuel, etc.).
    (2) The owner or operator shall document in the monitoring plan 
under Sec. 98.3(g)(5) how the monthly sampling of each type of fuel is 
performed.
    (C) For liquid fuels other than fuel oil and for biogas, sampling 
and analysis is required at least once per calendar quarter. To the 
extent practicable, consecutive quarterly samples shall be taken at 
least 30 days apart.
    (D) For other solid fuels (except MSW), weekly sampling is required 
to obtain composite samples, which are then analyzed monthly.
    (E) For gaseous fuels other than natural gas and biogas (e.g., 
process gas), daily sampling and analysis to determine the carbon 
content and molecular weight of the fuel is required if continuous, on-
line equipment, such as a gas chromatograph, is in place to make these 
measurements. Otherwise, weekly sampling and analysis shall be 
performed.
    (F) For mixtures (blends) of solid fuels, weekly sampling is 
required to obtain composite samples, which are analyzed monthly. For 
blends of liquid fuels, and for gas mixtures consisting only of natural 
gas and biogas, sampling and analysis is required at least once per 
calendar quarter. For gas mixtures that contain gases other than natural 
gas (including biogas), daily sampling and analysis to determine the 
carbon content and molecular weight of the fuel is required if 
continuous, on-line equipment is in place to make these measurements. 
Otherwise, weekly sampling and analysis shall be performed.
    (iii) If, for a particular type of fuel, sampling and analysis for 
carbon content and molecular weight is performed more often than the 
minimum frequency specified in paragraph (b)(3) of this section, the 
results of all valid fuel analyses shall be used in the GHG emission 
calculations.
    (iv) If, for a particular type of fuel, sampling and analysis for 
carbon content and molecular weight is performed at less than the 
minimum frequency specified in paragraph (b)(3) of this section, 
appropriate substitute data values shall be used in the emissions 
calculations, in accordance with the missing data procedures of Sec. 
98.35.
    (v) To calculate the CO2 mass emissions from combustion 
of a blend of fuels in the same state of matter (solid, liquid, or gas), 
you may either:
    (A) Apply Equation C-3, C-4 or C-5 of this subpart (as applicable) 
to each component of the blend, if the mass or volume, the carbon 
content, and (if applicable), the molecular weight of each component are 
accurately measured prior to blending; or
    (B) Consider the blend to be the ``fuel type.'' Then, at the 
frequency specified in paragraph (b)(3)(ii)(F) of this section, measure 
the carbon content and,

[[Page 636]]

if applicable, the molecular weight of the blend and calculate the 
annual average value of each parameter in the manner described in Sec. 
98.33(a)(2)(ii). Also measure the mass or volume of the blended fuel 
combusted during the reporting year. Substitute these measured values 
into Equation C-3, C-4, or C-5 of this subpart (as applicable).
    (4) You must use one of the following appropriate fuel sampling and 
analysis methods. The results of chromatographic analysis of the fuel 
may be used, provided that the gas chromatograph is operated, 
maintained, and calibrated according to the manufacturer's instructions. 
Alternatively, you may use a method published by a consensus-based 
standards organization if such a method exists, or you may use industry 
standard practice to determine the carbon content and molecular weight 
(for gaseous fuel) of the fuel. Consensus-based standards organizations 
include, but are not limited to, the following: ASTM International (100 
Barr Harbor Drive, P.O. Box CB700, West Conshohocken, Pennsylvania 
19428-B2959, (800) 262-1373, http://www.astm.org), the American National 
Standards Institute (ANSI, 1819 L Street, NW., 6th floor, Washington, DC 
20036, (202) 293-8020, http://www.ansi.org), the American Gas 
Association (AGA, 400 North Capitol Street, NW., 4th Floor, Washington, 
DC 20001, (202) 824-7000, http://www.aga.org), the American Society of 
Mechanical Engineers (ASME, Three Park Avenue, New York, NY 10016-5990, 
(800) 843-2763, http://www.asme.org), the American Petroleum Institute 
(API, 1220 L Street, NW., Washington, DC 20005-4070, (202) 682-8000, 
http://www.api.org), and the North American Energy Standards Board 
(NAESB, 801 Travis Street, Suite 1675, Houston, TX 77002, (713) 356-
0060, http://www.api.org). The method(s) used shall be documented in the 
Monitoring Plan required under Sec. 98.3(g)(5).
    (c) For the Tier 4 Calculation Methodology, the CO2, flow 
rate, and (if applicable) moisture monitors must be certified prior to 
the applicable deadline specified in Sec. 98.33(b)(5).
    (1) For initial certification, you may use any one of the following 
three procedures in this paragraph.
    (i) Sec. Sec. 75.20(c)(2), (c)(4), and (c)(5) through (c)(7) of 
this chapter and appendix A to part 75 of this chapter.
    (ii) The calibration drift test and relative accuracy test audit 
(RATA) procedures of Performance Specification 3 in appendix B to part 
60 of this chapter (for the CO2 concentration monitor) and 
Performance Specification 6 in appendix B to part 60 of this chapter 
(for the continuous emission rate monitoring system (CERMS)).
    (iii) The provisions of an applicable State continuous monitoring 
program.
    (2) If an O2 concentration monitor is used to determine 
CO2 concentrations, the applicable provisions of part 75 of 
this chapter, part 60 of this chapter, or an applicable State continuous 
monitoring program shall be followed for initial certification and on-
going quality assurance, and all required RATAs of the monitor shall be 
done on a percent CO2 basis.
    (3) For ongoing quality assurance, follow the applicable procedures 
in either appendix B to part 75 of this chapter, appendix F to part 60 
of this chapter, or an applicable State continuous monitoring program. 
If appendix F to part 60 of this chapter is selected for on-going 
quality assurance, perform daily calibration drift assessments for both 
the CO2 monitor (or surrogate O2 monitor) and the 
flow rate monitor, conduct cylinder gas audits of the CO2 
concentration monitor in three of the four quarters of each year (except 
for non-operating quarters), and perform annual RATAs of the 
CO2 concentration monitor and the CERMS.
    (4) For the purposes of this part, the stack gas volumetric flow 
rate monitor RATAs required by appendix B to part 75 of this chapter and 
the annual RATAs of the CERMS required by appendix F to part 60 of this 
chapter need only be done at one operating level, representing normal 
load or normal process operating conditions, both for initial 
certification and for ongoing quality assurance.
    (5) If, for any source operating hour, quality assured data are not 
obtained with a CO2 monitor (or surrogate O2

[[Page 637]]

monitor), flow rate monitor, or (if applicable) moisture monitor, use 
appropriate substitute data values in accordance with the missing data 
provisions of Sec. 98.35.
    (6) For certain applications where combined process emissions and 
combustion emissions are measured, the CO2 concentrations in 
the flue gas may be considerably higher than for combustion emissions 
alone. In such cases, the span of the CO2 monitor may, if 
necessary, be set higher than the specified levels in the applicable 
regulations. If the CO2 span value is set higher than 20 
percent CO2, the cylinder gas audits of the CO2 
monitor under appendix F to part 60 of this chapter may be performed at 
40 to 60 percent and 80 to 100 percent of span, in lieu of the 
prescribed calibration levels of 5 to 8 percent CO2 and 10 to 
14 percent CO2.
    (7) Hourly average data from the CEMS shall be validated in a manner 
consistent with one of the following: Sec. Sec. 60.13(h)(2)(i) through 
(h)(2)(vi) of this chapter; Sec. 75.10(d)(1) of this chapter; or the 
hourly data validation requirements of an applicable State CEM 
regulation.
    (d) Except as otherwise provided in Sec. 98.33(b)(1)(vi) and (vii), 
when municipal solid waste (MSW) is either the primary fuel combusted in 
a unit or the only fuel with a biogenic component combusted in the unit, 
determine the biogenic portion of the CO2 emissions using 
ASTM D6866-16 Standard Test Methods for Determining the Biobased Content 
of Solid, Liquid, and Gaseous Samples Using Radiocarbon Analysis) and 
ASTM D7459-08 Standard Practice for Collection of Integrated Samples for 
the Speciation of Biomass (Biogenic) and Fossil-Derived Carbon Dioxide 
Emitted from Stationary Emissions Sources (both incorporated by 
reference, see Sec. 98.7). Perform the ASTM D7459-08 sampling and the 
ASTM D6866-16 analysis at least once in every calendar quarter in which 
MSW is combusted in the unit. Collect each gas sample during normal unit 
operating conditions for at least 24 total (not necessarily consecutive) 
hours, or longer if the facility deems it necessary to obtain a 
representative sample. Notwithstanding this requirement, if the types of 
fuels combusted and their relative proportions are consistent throughout 
the year, the minimum required sampling time may be reduced to 8 hours 
if at least two 8-hour samples and one 24-hour sample are collected 
under normal operating conditions, and arithmetic average of the 
biogenic fraction of the flue gas from the 8-hour samples (expressed as 
a decimal) is within 5 percent of the biogenic 
fraction from the 24-hour test. There must be no overlapping of the 8-
hour and 24-hour test periods. Document the results of the demonstration 
in the unit's monitoring plan. If the types of fuels and their relative 
proportions are not consistent throughout the year, an optional sampling 
approach that facilities may wish to consider to obtain a more 
representative sample is to collect an integrated sample by extracting a 
small amount of flue gas (e.g., 1 to 5 cc) in each unit operating hour 
during the quarter. Separate the total annual CO2 emissions 
into the biogenic and non-biogenic fractions using the average 
proportion of biogenic emissions of all samples analyzed during the 
reporting year. Express the results as a decimal fraction (e.g., 0.30, 
if 30 percent of the CO2 is biogenic). When MSW is the 
primary fuel for multiple units at the facility, and the units are fed 
from a common fuel source, testing at only one of the units is 
sufficient.
    (e) For other units that combust combinations of biomass fuel(s) (or 
heterogeneous fuels that have a biomass component, e.g., tires) and 
fossil (or other non-biogenic) fuel(s), in any proportions, ASTM D6866-
16 and ASTM D7459-08 (both incorporated by reference, see Sec. 98.7) 
may be used to determine the biogenic portion of the CO2 
emissions in every calendar quarter in which biomass and non-biogenic 
fuels are co-fired in the unit. Follow the procedures in paragraph (d) 
of this section. If the primary fuel for multiple units at the facility 
consists of tires, and the units are fed from a common fuel source, 
testing at only one of the units is sufficient.
    (f) The records required under Sec. 98.3(g)(2)(i) shall include an 
explanation of how the following parameters are determined from company 
records

[[Page 638]]

(or, if applicable, from the best available information):
    (1) Fuel consumption, when the Tier 1 and Tier 2 Calculation 
Methodologies are used, including cases where Sec. 98.36(c)(4) applies.
    (2) Fuel consumption, when solid fuel is combusted and the Tier 3 
Calculation Methodology is used.
    (3) Fossil fuel consumption when Sec. 98.33(e)(2) applies to a unit 
that uses CEMS to quantify CO2 emissions and that combusts 
both fossil and biomass fuels.
    (4) Sorbent usage, when Sec. 98.33(d) applies.
    (5) Quantity of steam generated by a unit when Sec. 
98.33(a)(2)(iii) applies.
    (6) Biogenic fuel consumption and high heating value, as applicable, 
under Sec. Sec. 98.33(e)(5) and (e)(6).
    (7) Fuel usage for CH4 and N2O emissions 
calculations under Sec. 98.33(c)(4)(ii).
    (8) Mass of biomass combusted, for premixed fuels that contain 
biomass and fossil fuels under Sec. 98.33(e)(1)(iii).

Sec. 98.35  Procedures for estimating missing data.

    Whenever a quality-assured value of a required parameter is 
unavailable (e.g., if a CEMS malfunctions during unit operation or if a 
required fuel sample is not taken), a substitute data value for the 
missing parameter shall be used in the calculations.
    (a) For all units subject to the requirements of the Acid Rain 
Program, and all other stationary combustion units subject to the 
requirements of this part that monitor and report emissions and heat 
input data year-round in accordance with part 75 of this chapter, the 
missing data substitution procedures in part 75 of this chapter shall be 
followed for CO2 concentration, stack gas flow rate, fuel 
flow rate, high heating value, and fuel carbon content.
    (b) For units that use the Tier 1, Tier 2, Tier 3, and Tier 4 
Calculation Methodologies, perform missing data substitution as follows 
for each parameter:
    (1) For each missing value of the high heating value, carbon 
content, or molecular weight of the fuel, substitute the arithmetic 
average of the quality-assured values of that parameter immediately 
preceding and immediately following the missing data incident. If the 
``after'' value has not been obtained by the time that the GHG emissions 
report is due, you may use the ``before'' value for missing data 
substitution or the best available estimate of the parameter, based on 
all available process data (e.g., electrical load, steam production, 
operating hours). If, for a particular parameter, no quality-assured 
data are available prior to the missing data incident, the substitute 
data value shall be the first quality-assured value obtained after the 
missing data period.
    (2) For missing records of CO2 concentration, stack gas 
flow rate, percent moisture, fuel usage, and sorbent usage, the 
substitute data value shall be the best available estimate of the 
parameter, based on all available process data (e.g., electrical load, 
steam production, operating hours, etc.). You must document and retain 
records of the procedures used for all such estimates.

[74 FR 56374, Oct. 30, 2009, as amended at 75 FR 79150, Dec. 17, 2010]



Sec. 98.36  Data reporting requirements.

    (a) In addition to the facility-level information required under 
Sec. 98.3, the annual GHG emissions report shall contain the unit-level 
or process-level data specified in paragraphs (b) through (f) of this 
section, as applicable, for each stationary fuel combustion source 
(e.g., individual unit, aggregation of units, common pipe, or common 
stack) except as otherwise provided in this paragraph (a). For the data 
specified in paragraphs (b)(9)(iii), (c)(2)(ix), (e)(2)(i), 
(e)(2)(ii)(A), (e)(2)(ii)(C), (e)(2)(ii)(D), (e)(2)(iv)(A), 
(e)(2)(iv)(C), (e)(2)(iv)(F), and (e)(2)(ix)(D) through (F) of this 
section, the owner or operator of a stationary fuel combustion source 
that does not meet the criteria specified in paragraph (f) of this 
section may elect either to report the data specified in this sentence 
in the annual report or to use verification software according to Sec. 
98.5(b) in lieu of reporting these data. If you elect to use this 
verification software, you must use the verification software according 
to Sec. 98.5(b) for all of

[[Page 639]]

these data that apply to the stationary fuel combustion source.
    (b) Units that use the four tiers. You shall report the following 
information for stationary combustion units that use the Tier 1, Tier 2, 
Tier 3, or Tier 4 methodology in Sec. 98.33(a) to calculate 
CO2 emissions, except as otherwise provided in paragraphs (c) 
and (d) of this section:
    (1) The unit ID number.
    (2) A code representing the type of unit.
    (3) Maximum rated heat input capacity of the unit, in mmBtu/hr.
    (4) Each type of fuel combusted in the unit during the report year.
    (5) The methodology (i.e., tier) used to calculate the 
CO2 emissions for each type of fuel combusted (i.e., Tier 1, 
2, 3, or 4).
    (6) The methodology start date, for each fuel type.
    (7) The methodology end date, for each fuel type.
    (8) For a unit that uses Tiers 1, 2, or 3:
    (i) The annual CO2 mass emissions (including biogenic 
CO2), and the annual CH4, and N2O mass 
emissions for each type of fuel combusted during the reporting year, 
expressed in metric tons of each gas and in metric tons of 
CO2e; and
    (ii) Metric tons of biogenic CO2 emissions (if 
applicable).
    (9) For a unit that uses Tier 4:
    (i) If the total annual CO2 mass emissions measured by 
the CEMS consists entirely of non-biogenic CO2 (i.e., 
CO2 from fossil fuel combustion plus, if applicable, 
CO2 from sorbent and/or process CO2), report the 
total annual CO2 mass emissions, expressed in metric tons. 
You are not required to report the combustion CO2 emissions 
by fuel type.
    (ii) Report the total annual CO2 mass emissions measured 
by the CEMS. If this total includes both biogenic and non-biogenic 
CO2, separately report the annual non-biogenic CO2 
mass emissions and the annual CO2 mass emissions from biomass 
combustion, each expressed in metric tons. You are not required to 
report the combustion CO2 emissions by fuel type.
    (iii) An estimate of the heat input from each type of fuel listed in 
Table C-2 of this subpart that was combusted in the unit during the 
report year.
    (iv) The annual CH4 and N2O emissions for each 
type of fuel listed in Table C-2 of this subpart that was combusted in 
the unit during the report year, expressed in metric tons of each gas 
and in metric tons of CO2e.
    (10) Annual CO2 emissions from sorbent (if calculated 
using Equation C-11 of this subpart), expressed in metric tons.
    (11) If applicable, the plant code (as defined in Sec. 98.6).
    (c) Reporting alternatives for units using the four Tiers. You may 
use any of the applicable reporting alternatives of this paragraph to 
simplify the unit-level reporting required under paragraph (b) of this 
section:
    (1) Aggregation of units. If a facility contains two or more units 
(e.g., boilers or combustion turbines), each of which has a maximum 
rated heat input capacity of 250 mmBtu/hr or less, you may report the 
combined GHG emissions for the group of units in lieu of reporting GHG 
emissions from the individual units, provided that the use of Tier 4 is 
not required or elected for any of the units and the units use the same 
tier for any common fuels combusted. If this option is selected, the 
following information shall be reported instead of the information in 
paragraph (b) of this section:
    (i) Group ID number, beginning with the prefix ``GP''.
    (ii) [Reserved]
    (iii) Cumulative maximum rated heat input capacity of the group 
(mmBtu/hr). The cumulative maximum rated heat input capacity shall be 
determined as the sum of the maximum rated heat input capacities for all 
units in the group, excluding units less than 10 (mmBtu/hr).
    (iv) The highest maximum rated heat input capacity of any unit in 
the group (mmBtu/hr).
    (v) Each type of fuel combusted in the group of units during the 
reporting year.
    (vi) Annual CO2 mass emissions and annual CH4, 
and N2O mass emissions, aggregated for each type of fuel 
combusted in the group of units during the report year, expressed in 
metric tons of each gas and in metric tons of CO2e. If

[[Page 640]]

any of the units burn both fossil fuels and biomass, report also the 
annual CO2 emissions from combustion of all fossil fuels 
combined and annual CO2 emissions from combustion of all 
biomass fuels combined, expressed in metric tons.
    (vii) The methodology (i.e., tier) used to calculate the 
CO2 mass emissions for each type of fuel combusted in the 
units (i.e., Tier 1, Tier 2, or Tier 3).
    (viii) The methodology start date, for each fuel type.
    (ix) The methodology end date, for each fuel type.
    (x) The calculated CO2 mass emissions (if any) from 
sorbent expressed in metric tons.
    (xi) If applicable, the plant code (as defined in Sec. 98.6).
    (2) Monitored common stack or duct configurations. When the flue 
gases from two or more stationary fuel combustion units at a facility 
are combined together in a common stack or duct before exiting to the 
atmosphere and if CEMS are used to continuously monitor CO2 
mass emissions at the common stack or duct according to the Tier 4 
Calculation Methodology, you may report the combined emissions from the 
units sharing the common stack or duct, in lieu of separately reporting 
the GHG emissions from the individual units. This monitoring and 
reporting alternative may also be used when process off-gases or a 
mixture of combustion products and process gases are combined together 
in a common stack or duct before exiting to the atmosphere. Whenever the 
common stack or duct monitoring option is applied, the following 
information shall be reported instead of the information in paragraph 
(b) of this section:
    (i) Common stack or duct identification number, beginning with the 
prefix ``CS''.
    (ii) Number of units sharing the common stack or duct. Report ``1'' 
when the flue gas flowing through the common stack or duct includes 
combustion products and/or process off-gases, and all of the effluent 
comes from a single unit (e.g., a furnace, kiln, petrochemical 
production unit, or smelter).
    (iii) Combined maximum rated heat input capacity of the units 
sharing the common stack or duct (mmBtu/hr). This data element is 
required only when all of the units sharing the common stack are 
stationary fuel combustion units.
    (iv) Each type of fuel combusted in the units during the year.
    (v) The methodology (tier) used to calculate the CO2 mass 
emissions, i.e., Tier 4.
    (vi) The methodology start date.
    (vii) The methodology end date.
    (viii) Total annual CO2 mass emissions measured by the 
CEMS, expressed in metric tons. If any of the units burn both fossil 
fuels and biomass, separately report the annual non-biogenic 
CO2 mass emissions (i.e., CO2 from fossil fuel 
combustion plus, if applicable, CO2 from sorbent and/or 
process CO2) and the annual CO2 mass emissions 
from biomass combustion, each expressed in metric tons.
    (ix) An estimate of the heat input from each type of fuel listed in 
Table C-2 of this subpart that was combusted in the units sharing the 
common stack or duct during the report year.
    (x) For each type of fuel listed in Table C-2 of this subpart that 
was combusted during the report year in the units sharing the common 
stack or duct during the report year, the annual CH4 and 
N2O mass emissions from the units sharing the common stack or 
duct, expressed in metric tons of each gas and in metric tons of 
CO2e.
    (xi) If applicable, the plant code (as defined in Sec. 98.6).
    (3) Common pipe configurations. When two or more stationary 
combustion units at a facility combust the same type of liquid or 
gaseous fuel and the fuel is fed to the individual units through a 
common supply line or pipe, you may report the combined emissions from 
the units served by the common supply line, in lieu of separately 
reporting the GHG emissions from the individual units, provided that the 
total amount of fuel combusted by the units is accurately measured at 
the common pipe or supply line using a fuel flow meter, or, for natural 
gas, the amount of fuel combusted may be obtained from gas billing 
records. For Tier 3 applications, the flow meter shall be calibrated in 
accordance with Sec. 98.34(b). If a portion of the fuel measured (or 
obtained from gas billing

[[Page 641]]

records) at the main supply line is diverted to either: A flare; or 
another stationary fuel combustion unit (or units), including units that 
use a CO2 mass emissions calculation method in part 75 of 
this chapter; or a chemical or industrial process (where it is used as a 
raw material but not combusted), and the remainder of the fuel is 
distributed to a group of combustion units for which you elect to use 
the common pipe reporting option, you may use company records to 
subtract out the diverted portion of the fuel from the fuel measured (or 
obtained from gas billing records) at the main supply line prior to 
performing the GHG emissions calculations for the group of units using 
the common pipe option. If the diverted portion of the fuel is 
combusted, the GHG emissions from the diverted portion shall be 
accounted for in accordance with the applicable provisions of this part. 
When the common pipe option is selected, the applicable tier shall be 
used based on the maximum rated heat input capacity of the largest unit 
served by the common pipe configuration, except where the applicable 
tier is based on criteria other than unit size. For example, if the 
maximum rated heat input capacity of the largest unit is greater than 
250 mmBtu/hr, Tier 3 will apply, unless the fuel transported through the 
common pipe is natural gas or distillate oil, in which case Tier 2 may 
be used, in accordance with Sec. 98.33(b)(2)(ii). As a second example, 
in accordance with Sec. 98.33(b)(1)(v), Tier 1 may be used regardless 
of unit size when natural gas is transported through the common pipe, if 
the annual fuel consumption is obtained from gas billing records in 
units of therms or mmBtu. When the common pipe reporting option is 
selected, the following information shall be reported instead of the 
information in paragraph (b) of this section:
    (i) Common pipe identification number, beginning with the prefix 
``CP''.
    (ii) Cumulative maximum rated heat input capacity of the units 
served by the common pipe (mmBtu/hr). The cumulative maximum rated heat 
input capacity shall be determined as the sum of the maximum rated heat 
input capacities for all units served by the common pipe, excluding 
units less than 10 (mmBtu/hr).
    (iii) The highest maximum rated heat input capacity of any unit 
served by the common pipe (mmBtu/hr).
    (iv) The fuels combusted in the units during the reporting year.
    (v) The methodology used to calculate the CO2 mass 
emissions (i.e., Tier 1, Tier 2, or Tier 3).
    (vi) If the any of the units burns both fossil fuels and biomass, 
the annual CO2 mass emissions from combustion of all fossil 
fuels and annual CO2 emissions from combustion of all biomass 
fuels from the units served by the common pipe, expressed in metric 
tons.
    (vii) Annual CO2 mass emissions and annual CH4 
and N2O emissions from each fuel type for the units served by 
the common pipe, expressed in metric tons of each gas and in metric tons 
of CO2e.
    (viii) Methodology start date.
    (ix) Methodology end date.
    (x) If applicable, the plant code (as defined in Sec. 98.6).
    (4) The following alternative reporting option applies to facilities 
at which a common liquid or gaseous fuel supply is shared between one or 
more large combustion units, such as boilers or combustion turbines 
(including units subject to subpart D of this part and other units 
subject to part 75 of this chapter) and small combustion sources, 
including, but not limited to, space heaters, hot water heaters, and lab 
burners. In this case, you may simplify reporting by attributing all of 
the GHG emissions from combustion of the shared fuel to the large 
combustion unit(s), provided that:
    (i) The total quantity of the fuel combusted during the report year 
in the units sharing the fuel supply is measured, either at the ``gate'' 
to the facility or at a point inside the facility, using a fuel flow 
meter, billing meter, or tank drop measurements (as applicable);
    (ii) On an annual basis, at least 95 percent (by mass or volume) of 
the shared fuel is combusted in the large combustion unit(s), and the 
remainder is combusted in the small combustion sources. Company records 
may be used

[[Page 642]]

to determine the percentage distribution of the shared fuel to the large 
and small units; and
    (iii) The use of this reporting option is documented in the 
Monitoring Plan required under Sec. 98.3(g)(5). Indicate in the 
Monitoring Plan which units share the common fuel supply and the method 
used to demonstrate that this alternative reporting option applies. For 
the small combustion sources, a description of the types of units and 
the approximate number of units is sufficient.
    (d) Units subject to part 75 of this chapter. (1) For stationary 
combustion units that are subject to subpart D of this part, you shall 
report the following unit-level information:
    (i) Unit or stack identification numbers. Use exact same unit,

following the requirements of subpart C.



Sec. 98.53  Calculating GHG emissions.

    (a) You must determine annual N2O emissions from adipic 
acid production according to paragraphs (a)(1) or (2) of this section.
    (1) Use a site-specific emission factor and production data 
according to paragraphs (b) through (i) of this section.
    (2) Request Administrator approval for an alternative method of 
determining N2O emissions according to paragraphs (a)(2)(i) 
through (iv) of this section.
    (i) If you received Administrator approval for an alternative method 
of determining N2O emissions in the previous reporting year 
and your methodology is unchanged, your alternative method is 
automatically approved for the next reporting year.
    (ii) You must notify the EPA of your use of a previously approved 
alternative method in your annual report.
    (iii) Otherwise, you must submit the request within 45 days 
following promulgation of this subpart or within the first 30 days of 
each subsequent reporting year.
    (iv) If the Administrator does not approve your requested 
alternative method within 150 days of the end of the reporting year, you 
must determine the N2O emissions for the current reporting 
period using the procedures specified in paragraph (a)(1) of this 
section.

[[Page 651]]

the test point, according to the methods specified in Sec. 98.54(b) 
through (f). If multiple adipic acid production units exhaust to a 
common abatement technology and/or emission point, you must sample each 
process in the ducts before the emissions are combined, sample each 
process when only one process is operating, or sample the combined 
emissions when multiple processes are operating and base the site-
specific emission factor on the combined production rate of the multiple 
adipic acid production units.
    (2) You must conduct the performance test under normal process 
operating conditions.
    (3) You must measure the adipic acid production rate during the test 
and calculate the production rate for the test period in tons per hour.
    (c) Using the results of the performance test in paragraph (b) of 
this section, you must calculate an emission factor for each adipic acid 
unit according to Equation E-1 of this section:
[GRAPHIC] [TIFF OMITTED] TR28OC10.018

where:

EFN2O,z = Average facility-specific N2O 
          emission factor for each adipic acid production unit ``z'' (lb 
          N2O/ton adipic acid produced).
CN2O = N2O concentration per test run 
          during the performance test (ppm N2O).
1.14 x 10-7 = Conversion factor (lb/dscf-ppm N2O).
Q = Volumetric flow rate of effluent gas per test run during the 
          performance test (dscf/hr).
P = Production rate per test run during the performance test (tons 
          adipic acid produced/hr).
n = Number of test runs.

    (d) If the adipic acid production unit exhausts to any 
N2O abatement technology ``N'', you must determine the 
destruction efficiency according to paragraphs (d)(1), (d)(2), or (d)(3) 
of this section.
    (1) Use the manufacturer's specified destruction efficiency.
    (2) Estimate the destruction efficiency through process knowledge. 
Examples of information that could constitute process knowledge include 
calculations based on material balances, process stoichiometry, or 
previous test results provided the results are still relevant to the 
current vent stream conditions. You must document how process knowledge 
was used to determine the destruction efficiency.
    (3) Calculate the destruction efficiency by conducting an additional 
performance test on the vent stream following the N2O 
abatement technology.
    (e) If the adipic acid production unit exhausts to any 
N2O abatement technology ``N'', you must determine the annual 
amount of adipic acid produced while N2O abatement technology 
``N'' is operating according to Sec. 98.54(f). Then you must calculate 
the abatement factor for N2O abatement technology ``N'' 
according to Equation E-2 of this section.
[GRAPHIC] [TIFF OMITTED] TR29NO13.012

    (f) You must determine the annual amount of adipic acid produced 
according to Sec. 98.54(f).
    (g) You must calculate N2O emissions according to 
paragraph (g)(1), (2), (3), or

[[Page 652]]

(4) of this section for each adipic acid production unit.
    (1) If one N2O abatement technology ``N'' is located 
after your test point, you must use the emissions factor (determined in 
Equation E-1 of this section), the destruction efficiency (determined in

from a fossil-based feedstock produced via steam reforming of a 
hydrocarbon.
    (b) Ammonia manufacturing processes in which ammonia is manufactured 
through the gasification of solid and liquid raw material.



Sec. 98.71  Reporting threshold.

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



Sec. 98.72  GHGs to report.

    You must report:
    (a) CO2 process emissions from steam reforming of a 
hydrocarbon or the gasification of solid and liquid raw material, 
reported for each ammonia manufacturing process unit following the

Sec. 98.84  Monitoring and QA/QC requirements.

    (a) You must determine the weight fraction of total CaO and total 
MgO in CKD not recycled to the kiln from each kiln using ASTM C114-09, 
Standard Test Methods for Chemical Analysis of Hydraulic Cement 
(incoporated by reference, see Sec. 98.7). The monitoring must be 
conducted quarterly for each kiln from a CKD sample drawn either as CKD 
is exiting the kiln or from bulk CKD storage.
    (b) You must determine the weight fraction of total CaO and total 
MgO in clinker from each kiln using ASTM C114-09 Standard Test Methods 
for Chemical Analysis of Hydraulic Cement (incorporated by reference, 
see Sec. 98.7). The monitoring must be conducted monthly for each kiln 
from a monthly clinker sample drawn from bulk clinker storage if storage 
is dedicated to the specific kiln, or from a monthly arithmetic average 
of daily clinker samples drawn from the clinker conveying systems 
exiting each kiln.
    (c) The total organic carbon content (dry basis) of raw materials 
must be determined annually using ASTM C114-09 Standard Test Methods for 
Chemical Analysis of Hydraulic Cement (incorporated by reference, see 
Sec. 98.7) or a similar industry standard practice or method approved 
for total organic carbon determination in raw mineral materials. The 
analysis must be conducted either on sample material drawn from bulk raw 
kiln feed storage or on sample material drawn from bulk raw material 
storage for each category of raw material (i.e., limestone, sand, shale, 
iron oxide, and alumina). Facilities that opt to use the default total 
organic carbon factor provided in Sec. 98.83(d)(3), are not required to 
monitor for TOC.
    (d) The quantity of clinker produced monthly by each kiln must be 
determined by direct weight measurement of clinker using the same plant 
techniques used for accounting purposes, such as reconciling weigh 
hopper or belt weigh feeder measurements against inventory measurements. 
As an alternative, facilities may also determine clinker production by 
direct measurement of raw kiln feed and application of a kiln-specific 
feed-to-clinker factor. Facilities that opt to use a feed-to-clinker 
factor must verify the accuracy of this factor on a monthly basis.
    (e) The quantity of CKD not recycled to the kiln generated by each 
kiln must be determined quarterly using the same plant techniques used 
for accounting purposes, such as direct weight measurement using weigh 
hoppers, truck weigh scales, or belt weigh feeders.
    (f) The annual quantity of raw kiln feed or annual quantity of each 
category of raw materials consumed by the facility (e.g., limestone, 
sand, shale, iron oxide, and alumina) must be determined monthly by 
direct weight measurement using the same plant instruments used for 
accounting purposes, such as weigh hoppers, truck weigh scales, or belt 
weigh feeders.
    (g) The monthly non-calcined CaO and MgO that remains in the clinker 
in the form of CaCO3 or that enters the kiln as a non-
carbonate species may be assumed to be a default value of 0.0 or may be 
determined monthly by careful chemical analysis of feed material and 
clinker material from each kiln using well documented analytical and 
calculational methods or the appropriate industry standard practice.

[[Page 670]]

    (h) The quarterly non-calcined CaO and MgO that remains in the CKD 
in the form of CaCO3 or that enters the kiln as a non-
carbonate species may be assumed to be a default value of 0.0 or may be 
determined quarterly by careful chemical analysis of feed material and 
CKD material from each kiln using well documented analytical and 
calculational methods or the appropriate industry standard practice.

missing, facilities must undertake a new analysis.
    (c) For each missing value of monthly clinker production the 
substitute data value must be the best available estimate of the monthly 
clinker production based on information used for accounting purposes, or 
use the maximum tons per day capacity of the system and the number of 
days per month.
    (d) For each missing value of monthly raw material consumption the 
substitute data value must be the best available estimate of the monthly 
raw material consumption based on information used for accounting 
purposes (such as purchase records), or use the maximum tons per day raw 
material throughput of the kiln and the number of days per month.

          mode, as defined in Sec. 98.98, when at least one of the 
          tools connected to abatement system p is in operation.
UTijp = Total time, in minutes per year, in which abatement 
          system p has at least one associated tool in operation. For

          operated for 525,600 minutes per year. For tools that were 
          installed or uninstalled during the year, you must prorate the 
          operating time to account for the days in which the tool was 
          not installed; treat any partial day that a tool was installed 
          as a full day (1,440 minutes)

[[Page 679]]

          of tool operation. For an abatement system that has more than 
          one connected tool, the tool operating time is 525,600 minutes 
          per year if at least one tool was installed at all times 
          throughout the year. If you have tools that are idle with no 
          gas flow through the tool for part of the year, you may 
          calculate total tool time using the actual time that gas is 
          flowing through the tool.

factor method in paragraph (a) of this section, you may calculate fab-

developed from stack testing. To use the method in this paragraph, you 
must first make a preliminary estimate of the fluorinated GHG emissions 
from each stack system in the fab under paragraph (i)(1) of this

and I-9 of this subpart. You must include any intermittent low-use 
fluorinated GHGs, as defined in Sec. 98.98 of this subpart, in any 
preliminary estimates. When using Equations I-8 and I-9 of this subpart 
for the purposes of this paragraph (i)(1), you must also adhere to the 
procedures in paragraphs (i)(1)(i) to (iv) of this section to calculate 
preliminary estimates.
    (i) When you are calculating preliminary estimates for the purpose 
of this paragraph (i)(1), you must consider the subscript ``j'' in 
Equations I-8 and I-9, and I-13 of this subpart to mean ``stack system'' 
instead of ``process sub-type or process type.'' For the value of 
aij, the fraction of input gas i that is used in tools with 
abatement systems, for use in Equations I-8 and I-9, you may use the 
ratio of the number of tools using input gas i that have abatement 
systems that are vented to the stack system for which you are 
calculating the preliminary estimate to the total number of tools using 
input gas i that are vented to that stack system, expressed as a decimal 
fraction. In calculating the preliminary estimates, you must account for 
the effect of any fluorinated GHG abatement system meeting the 
definition of abatement system in Sec. 98.98. You may use this approach 
to determining aij only for this preliminary estimate.
    (ii) You must use representative data from the previous reporting 
year to estimate the consumption of input gas i as calculated in 
Equation I-13 of this subpart and the fraction of input gas i and by-
product gas k destroyed in abatement systems for each stack system as 
calculated by Equations I-24A and I-24B of this subpart. If you were not 
required to submit an annual report under subpart I for the previous 
reporting year and data from the previous reporting year are not 
available, you may estimate the consumption of input gas i and the 
fraction of input gas i destroyed in abatement systems based on 
representative operating data from a period of at least 30 days in the 
current reporting year. When calculating the consumption of input gas i 
using Equation I-13 of this subpart, the term ``fij'' is 
replaced with the ratio of the number of tools using input gas i that 
are vented to the stack system for which you are calculating the 
preliminary estimate to the total number of tools in the fab using input 
gas i, expressed as a decimal fraction. You may use this approach to 
determining fij only for this preliminary estimate.
    (iii) You must use representative data from the previous reporting 
year to estimate the total uptime of all abatement systems for the stack 
system as calculated by Equation I-23 of this subpart, instead of using 
Equation I-15 of this subpart to calculate the average uptime factor. If 
you were not required to submit an annual report under subpart I for the 
previous reporting year and data from the previous reporting year are 
not available, you may estimate the total uptime of all abatement 
systems for the stack system based on representative operating data from 
a period of at least 30 days in the current reporting year.
    (iv) If you anticipate an increase or decrease in annual consumption 
or emissions of any fluorinated GHG, or the number of tools connected to 
abatement systems greater than 10 percent for the current reporting year 
compared to the previous reporting year, you must account for the 
anticipated change in your preliminary estimate. You may account for 
such a change using a quantifiable metric (e.g., the ratio of the number 
of tools that are expected to be vented to the stack system in the 
current year as compared to the previous reporting year, ratio of the 
expected number of wafer starts in the current reporting year as 
compared to the previous reporting year), engineering judgment, or other 
industry standard practice.
    (2) Method selection for stack systems in the fab. If the 
calculations under paragraph (i)(1) of this section, as well as any 
subsequent annual measurements and calculations under this subpart, 
indicate that the stack system meets the criteria in paragraph (i)(2)(i) 
through (iii) of this section, then you may comply with either paragraph 
(i)(3) of this section (stack test method) or paragraph (i)(4) of this 
section (method to estimate emissions from the stack systems that are 
not tested). If the stack system does not meet all three criteria in 
paragraph (i)(2)(i) through (iii) of this section, then you must comply

[[Page 681]]

with the stack test method specified in paragraph (i)(3) of this 
section.
    (i) The sum of annual emissions of fluorinated GHGs from all of the 
combined stack systems that are not tested in the fab must be less than 
10,000 metric ton CO2e per year.
    (ii) When all stack systems in the fab are ordered from lowest to 
highest emitting in metric ton CO2e of fluorinated GHG per 
year, each of the stack systems that is not tested must be within the 
set of the fab's lowest emitting fluorinated GHG stack systems that 
together emit 15 percent or less of total CO2e fluorinated 
GHG emissions from the fab.
    (iii) Fluorinated GHG emissions from each of the stack systems that 
is not tested can only be attributed to particular process tools during 
the test (that is, the stack system that is not tested cannot be used as 
an alternative emission point or bypass stack system from other process 
tools not attributed to the untested stack system).
    (3) Stack system stack test method. For each stack system in the fab 
for which testing is required, measure the emissions of each fluorinated 
GHG from the stack system by conducting an emission test. In addition, 
measure the fab-specific consumption of each fluorinated GHG by the 
tools that are vented to the stack systems tested. Measure emissions and 
consumption of each fluorinated GHG as specified in Sec. 98.94(j). 
Develop fab-specific emission factors and calculate fab-level 
fluorinated GHG emissions using the procedures specified in paragraph 
(i)(3)(i) through (viii) of this section. All emissions test data and 
procedures used in developing emission factors must be documented and 
recorded according to Sec. 98.97.
    (i) You must measure, and, if applicable, apportion the fab-specific 
fluorinated GHG consumption of the tools that are vented to the stack 
systems that are tested during the emission test as specified in Sec. 
98.94(j)(3). Calculate the consumption for each fluorinated GHG for the 
test period.
    (ii) You must calculate the emissions of each fluorinated GHG 
consumed as an input gas using Equation I-17 of this subpart and each 
fluorinated GHG formed as a by-product gas using Equation I-18 of this 
subpart and the procedures specified in paragraphs (i)(3)(ii)(A) through 
(E) of this section. If a stack system is comprised of multiple stacks, 
you must sum the emissions from each stack in the stack system when 
using Equation I-17 or Equation I-18 of this subpart.

    (A) If a fluorinated GHG is consumed during the sampling period, but 
emissions are not detected, use one-half of the field detection limit 
you determined for that fluorinated GHG according to Sec. 98.94(j)(2) 
for the value of ``Xism'' in Equation I-17.
    (B) If a fluorinated GHG is consumed during the sampling period and 
detected intermittently during the sampling period, use the detected

Equation I-18.
    (E) If a fluorinated GHG is not consumed during the sampling period 
and is a possible by-product gas as listed in Table I-17 of this

UTpf = Total time, in minutes per year, in which the tool(s) 
          connected at any point during the year to abatement system p, 
          in fab f could be in operation. For determining the amount of 
          tool operating time, you may assume that tools that were 
          installed for the whole of the year were operated for 525,600 
          minutes per year. For tools that were installed or uninstalled 
          during the year, you must prorate the operating time to 
          account for the days in which the tool was not installed; 
          treat any partial day that a tool was installed as a full day 
          (1,440 minutes) of tool operation. For an abatement system

    (4) Method to calculate emissions from stack systems that are not 
tested. You must calculate annual fab-level emissions of each 
fluorinated GHG input gas and byproduct gas for those fluorinated GHG 
listed in paragraphs (i)(4)(i) and (ii) of this section using default 
utilization and by-product formation rates as shown in Table I-11, I-12, 
I-13, I-14, or I-15 of this subpart, as applicable, and by using 
Equations I-8, I-9, and I-13 of this subpart. When using Equations I-8, 
I-9, and I-13 to fulfill the requirements of this paragraph, you must 
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)(4)(ii) of this section. You also must use 
the results of Equations 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

use fluorinated GHG as defined in Sec. 98.98 of this subpart using the 
default utilization and by-product formation rates and equations 
specified in paragraph (i)(4) of this section. If a fluorinated GHG was 
not being used during the stack testing and does not meet the definition 
of intermittent low-use fluorinated GHG in Sec. 98.98, then you must 
test the stack systems associated with the use of that fluorinated GHG 
at a time when that gas is in use at a magnitude that would allow you to 
determine an emission factor for that gas according to the procedures 
specified in paragraph (i)(3) of this section.
    (ii) Calculate emissions from consumption of each fluorinated GHG 
used in tools vented to stack systems that meet the criteria specified 
in paragraphs (i)(2)(i) through (i)(2)(iii) of this section, and were 
not tested according to the procedures in paragraph (i)(3) of this 
section. Calculate emissions using the default utilization and by-
product formation rates and equations specified in paragraph (i)(4) of 
this section. If you are using a fluorinated GHG not listed in Tables I-
11, I-12, I-13, I-14, or I-15 of this subpart, then you must assume 
utilization and by-product formation rates of zero for that fluorinated 
GHG.
    (5) To determine the total emissions of each fluorinated GHG from 
each fab under this stack testing option, you must sum the emissions of 
each fluorinated GHG determined from the procedures in paragraph (i)(3) 
of this section with the emissions of the same fluorinated GHG 
determined from the procedures in paragraph (i)(4) of this section. Sum 
the total emissions of each fluorinated GHG from all fabs at your 
facility to determine the facility-level emissions of each fluorinated 
GHG.

Sec. 98.94  Monitoring and QA/QC requirements.

    (a) [Reserved]
    (b) For purposes of Equation I-12 of this subpart, you must estimate 
fab-wide gas-specific heel factors for each container type for each gas 
used, according to the procedures in paragraphs (b)(1) through (b)(5) of 
this section. This paragraph (b) does not apply to fluorinated GHGs or 
N2O that your fab uses in quantities of less than 50 kg in 
one reporting year and for which you calculate emissions as equal to 
consumption under Sec. 98.93(a)(1), (a)(2), or (b), or for any 
intermittent low-use fluorinated GHG for which you calculate emissions 
according to Sec. 98.93(i)(4)(i).
    (1) Base your fab-wide gas-specific heel factors on the trigger 
point for change out of a container for each container size and type for 
each gas used. Fab-wide gas-specific heel factors must be expressed as 
the ratio of the trigger point for change out, in terms of mass, to the 
initial mass in the container, as determined by paragraphs (b)(2) and 
(3) of this section.
    (2) The trigger points for change out you use to calculate fab-wide 
gas-specific heel factors in paragraph (b)(1) of this section must be 
determined by monitoring the mass or the pressure of your containers. If 
you monitor the pressure, convert the pressure to mass using the ideal 
gas law, as displayed in Equation I-25 of this subpart, with the 
appropriate Z value selected based upon the properties of the gas.

Where:

p = Absolute pressure of the gas (Pa).
V = Volume of the gas container (m\3\).
Z = Compressibility factor.
n = Amount of substance of the gas (moles).

T = Absolute temperature (K).


[[Page 687]]


    (3) The initial mass you use to calculate a fab-wide gas-specific 
heel factor in paragraph (b)(1) of this section may be based on the 
weight of the gas provided to you in gas supplier documents; however, 
you remain responsible for the accuracy of these masses and weights 
under this subpart.
    (4) If a container is changed in an exceptional circumstance, as 
specified in paragraphs (b)(4)(i) and (ii) of this section, you must 
weigh that container or measure the pressure of that container with a 
pressure gauge, in place of using a heel factor to determine the 
residual weight of gas. When using mass-based trigger points for change 
out, you must determine if an exceptional circumstance has occurred 
based on the net weight of gas in the container, excluding the tare 
weight of the container.
    (i) For containers with a maximum storage capacity of less than 9.08 
kg (20 lbs) of gas, an exceptional circumstance is a change out point 
that differs by more than 50 percent from the trigger point for change 
out used to calculate your fab-wide gas-specific heel factor for that 
gas and container type.
    (ii) For all other containers, an exceptional circumstance is a 
change out point that differs by more than 20 percent from the trigger 
point for change out used to calculate your fab-wide gas-specific heel 
factor for that gas and container type.
    (5) You must re-calculate a fab-wide gas-specific heel factor if you 
execute a process change to modify the trigger point for change out for 
a gas and container type that differs by more than 5 percent from the 
previously used trigger point for change out for that gas and container 
type.
    (c) You must develop apportioning factors for fluorinated GHG and 
N2O consumption (including the fraction of gas consumed by 
process tools connected to abatement systems as in Equations I-8, I-9, 
I-10, I-19, I-20, I-21, and I-22 of this subpart), to use in the 
equations of this subpart for each input gas i, process sub-type, 
process type, stack system, and fab as appropriate, using a fab-specific 
engineering model that is documented in your site GHG Monitoring Plan as 
required under Sec. 98.3(g)(5). This model must be based on a 
quantifiable metric, such as wafer passes or wafer starts, or direct 
measurement of input gas consumption as specified in paragraph (c)(3) of 
this section. To verify your model, you must demonstrate its precision 
and accuracy by adhering to the requirements in paragraphs (c)(1) and 
(2) of this section.
    (1) You must demonstrate that the fluorinated GHG and N2O 
apportioning factors are developed using calculations that are 
repeatable, as defined in Sec. 98.98.
    (2) You must demonstrate the accuracy of your fab-specific model by 
comparing the actual amount of input gas i consumed and the modeled 
amount of input gas i consumed in the fab, as follows:
    (i) You must analyze actual and modeled gas consumption for a period 
when the fab is at a representative operating level (as defined in Sec. 
98.98) lasting at least 30 days but no more than the reporting year.
    (ii) You must compare the actual gas consumed to the modeled gas 
consumed for one fluorinated GHG reported under this subpart for the 
fab. You must certify that the fluorinated GHG selected for comparison 
corresponds to the largest quantity, on a mass basis, of fluorinated GHG 
consumed at the fab during the reporting year for which you are required 
to apportion following the procedures specified in Sec. 98.93(a), (b), 
or (i). You may compare the actual gas consumed to the modeled gas 
consumed for two fluorinated GHGs and demonstrate conformance according 
to paragraph (c)(2)(iii) of this section on an aggregate use basis for 
both fluorinated GHGs if one of the fluorinated GHGs selected for 
comparison corresponds to the largest quantity, on a mass basis, of 
fluorinated GHGs used at each fab that requires apportionment during the 
reporting year.
    (iii) You must demonstrate that the comparison performed for the 
largest quantity of gas(es), on a mass basis, consumed in the fab in 
paragraph (c)(2)(ii) of this section, does not result in a difference 
between the actual and modeled gas consumption that exceeds 20 percent 
relative to actual gas consumption, reported to two significant

[[Page 688]]

figures using standard rounding conventions.
    (iv) If you are required to apportion gas consumption and you use 
the procedures in Sec. 98.93(i) to calculate annual emissions from a 
fab, you must verify your apportioning factors using the procedures in 
paragraphs (c)(2)(ii) and (iii) of this section such that the time 
period specified in paragraph (c)(2)(i) of this section and the last day 
you perform the sampling events specified under Sec. 98.93(i)(3) occur 
in the same accounting month.
    (v) If your facility has multiple fabs with a single centralized 
fluorinated-GHG supply system, you must verify that your apportioning 
model can apportion fluorinated GHG consumption among the fabs by 
adhering to the procedures in paragraphs (c)(2)(ii) through (c)(2)(iv) 
of this section.
    (3) As an alternative to developing apportioning factors for 
fluorinated GHG and N2O consumption using a fab-specific 
engineering model, you may develop apportioning factors through the use 
of direct measurement using gas flow meters and weigh scales to measure 
process sub-type, process type, stack system, or fab-specific input gas 
consumption. You may use a combination of apportioning factors developed 
using a fab-specific engineering model and apportioning factors 
developed through the use of direct measurement, provided this is 
documented in your site GHG Monitoring Plan as required under 
98.3(g)(5).
    (d)-(e) [Reserved]
    (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.
    (1) You must certify and document that the abatement systems are 
properly installed, operated, and maintained according to the site 
maintenance plan for abatement systems that is developed and maintained 
in your records as specified in Sec. 98.97(d)(9).
    (2) You must calculate and document the uptime of abatement systems 
using Equation I-15 or I-23 of this subpart, as applicable.
    (3) If you use default destruction and removal efficiency values in 
your emissions calculations under Sec. 98.93(a), (b), and/or (i), you 
must certify and document that the abatement systems at your facility 
for which you use default destruction or removal efficiency values are 
specifically designed for fluorinated GHG or N2O abatement, 
as applicable. If you elect to calculate fluorinated GHG emissions using 
the stack test method under Sec. 98.93(i), you must also certify that 
you have included and accounted for all abatement systems designed for 
fluorinated GHG abatement and any respective downtime in your emissions 
calculations under Sec. 98.93(i)(3).
    (4) If you do not use the default destruction or removal efficiency 
values in Table I-16 of this subpart to calculate and report controlled 
emissions, including situations in which your fab employs abatement 
systems not specifically designed for fluorinated GHG or N2O 
abatement and you elect to reflect emission reduction due to these 
systems, you must use an average of properly measured destruction or 
removal efficiencies for each gas and process sub-type or process type 
combination, as applicable, determined in accordance with procedures in 
paragraphs (f)(4)(i) through (vi) of this section. You must not use a 
default value from Table I-16 of this subpart for any abatement system 
not specifically designed for fluorinated GHG and N2O 
abatement, or for any gas and process type combination for which you 
have measured the destruction or removal efficiency according to the 
requirements of paragraphs (f)(4)(i) through (vi) of this section.
    (i) A properly measured destruction or removal efficiency value must 
be determined in accordance with EPA 430-R-10-003 (incorporated by 
reference, see

[[Page 689]]

Sec. 98.7), or according to an alternative method approved by the 
Administrator (or authorized representative) as specified in paragraph 
(k) of this section. If you are measuring destruction or removal 
efficiency according to EPA 430-R-10-003 (incorporated by reference, see 
Sec. 98.7), you may follow the alternative procedures specified in 
Appendix A to this subpart.
    (ii) You must select and properly measure the destruction or removal 
efficiency for a random sample of abatement systems to include in a 
random sampling abatement system testing program in accordance with 
procedures in paragraphs (f)(4)(ii)(A) and (B) of this section.
    (A) For the first 2 years for which your fab is required to report 
emissions of fluorinated GHG and N2O, for each abatement 
system gas and process sub-type or process type combination, as 
applicable, a random sample of a minimum of 10 percent of installed 
abatement systems must be tested annually for a total of a minimum of 20 
percent, or a minimum of 20 percent may be tested in the first year. For 
every 3-year period following the initial 2-year period, a random sample 
of at least 15 percent of installed abatement systems must be tested for 
each gas and process sub-type or process type combination; you may test 
15-percent in the first year of the 3-year period, but you must test at 
least 5 percent each year until 15 percent are tested. For each 3-year 
period, you must determine the number of abatement systems to be tested 
based on the average number of abatement systems in service over the 3-
year period. If the required percent of the total number of abatement 
systems to be tested for each gas and process sub-type or process type 
combination does not equate to a whole number, the number of systems to 
be tested must be determined by rounding up to the nearest integer. 
Except as provided in paragraph (f)(4)(v) of this section, you may not 
retest an abatement system for any gas and process sub-type or process 
type combination, as applicable, until all of the abatement systems for 
that gas and process sub-type or process type combination have been 
tested.
    (B) If testing of a randomly selected abatement system would be 
disruptive to production, you may replace that system with another 
randomly selected system for testing and return the system to the 
sampling pool for subsequent testing. Any one abatement system must not 
be replaced by another randomly selected system for more than three 
consecutive selections. When you have to replace a system in one year, 
you may select that specific system to be tested in one of the next two 
sampling years so that you may plan testing of that abatement system to 
avoid disrupting production.
    (iii) If you elect to take credit for abatement system destruction 
or removal efficiency before completing testing on 20 percent of the 
abatement systems for that gas and process sub-type or process type 
combination, as applicable, you must use default destruction or removal 
efficiencies for a gas and process type combination. You must not use a 
default value from Table I-16 of this subpart for any abatement system 
not specifically designed for fluorinated GHG and N2O 
abatement, and must not take credit for abatement system destruction or 
removal efficiency before completing testing on 20 percent of the 
abatement systems for that gas and process sub-type or process type 
combination, as applicable. Following testing on 20 percent of abatement 
systems for that gas and process sub-type or process type combination, 
you must calculate the average destruction or removal efficiency as the 
arithmetic mean of all test results for that gas and process sub-type or 
process type combination, until you have tested at least 30 percent of 
all abatement systems for each gas and process sub-type or process type 
combination. After testing at least 30 percent of all systems for a gas 
and process sub-type or process type combination, you must use the 
arithmetic mean of the most recent 30 percent of systems tested as the 
average destruction or removal efficiency. You may include results of 
testing conducted on or after January 1, 2011 for use in determining the 
site-specific destruction or removal efficiency for a given gas and 
process sub-type or process type combination if the testing was

[[Page 690]]

conducted in accordance with the requirements of paragraph (f)(4)(i) of 
this section.
    (iv) If a measured destruction or removal efficiency is below the 
manufacturer-claimed fluorinated GHG or N2O destruction or 
removal efficiency for any abatement system specifically designed for 
fluorinated GHG or N2O abatement and the abatement system is 
installed, operated, and maintained in accordance with the site 
maintenance plan for abatement systems that is developed and maintained 
in your records as specified in Sec. 98.97(d)(9), the measured 
destruction or removal efficiency must be included in the calculation of 
the destruction or removal efficiency value for that gas and process 
sub-type or process type.
    (v) If a measured destruction or removal efficiency is below the 
manufacturer-claimed fluorinated GHG or N2O destruction or 
removal efficiency for any abatement system specifically designed for 
fluorinated GHG or N2O abatement and the abatement system is 
not installed, operated, or maintained in accordance with the site 
maintenance plan for abatement systems that is developed and maintained 
in your records as specified in Sec. 98.97(d)(9), you must implement 
corrective action and perform a retest to replace the measured value 
within the reporting year. In lieu of retesting within the reporting 
year, you may use the measured value in calculating the average 
destruction or removal efficiency for the reporting year, implement 
corrective action, and then include the same system in the next 
abatement system testing period in addition to the testing of randomly 
selected systems for that next testing period. Regardless of whether you 
use the lower measured destruction or removal efficiency and when you 
perform the retest of the abatement system, you must count the time that 
the abatement system is not operated and maintained according to the 
site maintenance plan for abatement systems as not being in operational 
mode for purposes of calculating abatement system uptime.
    (vi) If your fab uses redundant abatement systems, you may account 
for the total abatement system uptime (that is, the time that at least 
one abatement system is in operational mode) calculated for a specific 
exhaust stream during the reporting year.
    (g) You must adhere to the QA/QC procedures of this paragraph when 
calculating fluorinated GHG and N2O emissions from 
electronics manufacturing production processes:
    (1)-(2) [Reserved]
    (3) Follow the QA/QC procedures in accordance with those in EPA 430-
R-10-003 (incorporated by reference, see Sec. 98.7), or the applicable 
QA/QC procedures specified in an alternative method approved by the 
Administrator (or authorized representative) according to paragraph (k) 
of this section, when calculating abatement systems destruction or 
removal efficiencies. If you are measuring destruction or removal 
efficiency according to EPA 430-R-10-003 (incorporated by reference, see 
Sec. 98.7), and you elect to follow the alternative procedures 
specified in Appendix A to this subpart according to paragraph (f)(4)(i) 
of this section, you must follow any additional QA/QC procedures 
specified in Appendix A to this subpart.
    (4) As part of normal operations for each fab, the inventory of gas 
stored in containers at the beginning of the reporting year must be the 
same as the inventory of gas stored in containers at the end of the 
previous reporting year. You must maintain records documenting the year 
end and year beginning inventories under Sec. 98.97(a).
    (h) You must adhere to the QA/QC procedures of this paragraph (h) 
when calculating annual gas consumption for each fluorinated GHG and 
N2O used at each fab and emissions from the use of each 
fluorinated heat transfer fluid on a fab basis.
    (1) Review all inputs to Equations I-11 and I-16 of this subpart to 
ensure that all inputs and outputs are accounted for.
    (2) Do not enter negative inputs into the mass balance Equations I-
11 and I-16 of this subpart and ensure that no negative emissions are 
calculated.
    (3) Ensure that the inventory at the beginning of one reporting year 
is identical to the inventory at the end of the previous reporting year. 
You must maintain records documenting the year

[[Page 691]]

end and year beginning inventories under Sec. 98.97(a) and (r).
    (4) Ensure that the total quantity of gas i in containers in service 
at the end of a reporting year is accounted for as if the in-service 
containers were full for Equation I-11 of this subpart. Ensure also that 
the same quantity is accounted for in the inventory of input gas i 
stored in containers at the beginning of the subsequent reporting year.
    (i) All flow meters, weigh scales, pressure gauges, and thermometers 
used to measure quantities that are monitored under this section or used 
in calculations under Sec. 98.93 must meet the calibration and accuracy 
requirements specified in Sec. 98.3(i).
    (j) Stack test methodology. For each fab for which you calculate 
annual emissions for any fluorinated GHG emitted from your facility 
using the stack test method according to the procedure specified in 
Sec. 98.93(i)(3), you must adhere to the requirements in paragraphs 
(j)(1) through (8) of this section. You may request approval to use an 
alternative stack test method and procedure according to paragraph (k) 
of this section.
    (1) Stack system testing. Conduct an emissions test for each 
applicable stack system according to the procedures in paragraphs 
(j)(1)(i) through (iv) of this section.
    (i) You must conduct an emission test during which the fab is 
operating at a representative operating level, as defined in Sec. 
98.98, and with the abatement systems connected to the stack system 
being tested operating with at least 90 percent uptime, averaged over 
all abatement systems, during the 8-hour (or longer) period for each 
stack system, or at no less than 90 percent of the abatement system 
uptime rate measured over the previous reporting year, averaged over all 
abatement systems.
    (ii) You must measure for the expected and possible by-products 
identified in Table I-17 of this subpart and those fluorinated GHGs used 
as input fluorinated GHG in process tools vented to the stack system, 
except for any intermittent low-use fluorinated GHG as defined in Sec. 
98.98. You must calculate annual emissions of intermittent low-use 
fluorinated GHGs by adhering to the procedures in Sec. 98.93(i)(4)(i).
    (iii) If a fluorinated GHG being consumed in the reporting year was 
not being consumed during the stack testing and does not meet the 
definition of intermittent low-use fluorinated GHG in Sec. 98.98, then 
you must test the stack systems associated with the use of that 
fluorinated GHG at a time when that gas is in use at a magnitude that 
would allow you to determine an emission factor for that gas. If a 
fluorinated GHG consumed in the reporting year was not being consumed 
during the stack testing and is no longer in use by your fab (e.g., use 
of the gas has become obsolete or has been discontinued), then you must 
calculate annual emissions for that fluorinated GHG according to the 
procedure specified in Sec. 98.93(i)(4).
    (iv) Although all applicable stack systems are not required to be 
tested simultaneously, you must certify that no significant changes in 
stack flow configuration occur between tests conducted for any 
particular fab in a reporting year. You must certify that no more than 
10 percent of the total number of fluorinated GHG emitting process tools 
are connected or disconnected from a stack system during testing. You 
must also certify that no process tools that were in operation at the 
start of the test period have been moved to a different stack system 
during the test period (i.e., during or in between testing of individual 
stack systems) and that no point-of-use abatement systems have been 
permanently removed from service during the test period. You must 
document any changes in stack flow configuration in the emissions test 
data and report required to be kept as records under Sec. 98.97(i)(4).
    (2) Test methods and procedures. You must adhere to the applicable 
test methods and procedures specified in Table I-9 to this subpart, or 
adhere to an alternative method approved by the Administrator (or 
authorized representative) according to paragraph (k) of this section. 
If you select Method 320 of 40 CFR part 63, Appendix A to measure the 
concentration of each fluorinated GHG in the stack system,

[[Page 692]]

you must complete a method validation according to Section 13 of Method 
320 of 40 CFR part 63, Appendix A for each FTIR system (hardware and 
software) and each tester (testing company). Method 320 validation is 
necessary when any change occurs in instrumentation, tester (i.e., 
testing company), or stack condition (e.g., acid gas vs. base). 
Measurement of new compounds require validation for those compounds 
according to Section 13 of Method 320 of 40 CFR part 63, Appendix A. The 
field detection limits achieved under your test methods and procedures 
must fall at or below the maximum field detection limits specified in 
Table I-10 to this subpart.
    (3) Fab-specific fluorinated GHG consumption measurements. You must 
determine the amount of each fluorinated GHG consumed by each fab during 
the sampling period for all process tools connected to the stack systems 
tested under Sec. 98.93(i)(3), according to the procedures in 
paragraphs (j)(3)(i) and (ii) of this section. This determination must 
include apportioning gas consumption between stack systems that are 
being tested and those that are not tested under Sec. 98.93(i)(2).
    (i) Measure fluorinated GHG consumption using gas flow meters, 
scales, or pressure measurements. Measure the mass or pressure, as 
applicable, at the beginning and end of the sampling period and when 
containers are changed out. If you elect to measure gas consumption 
using pressure (i.e., because the gas is stored in a location above its 
critical temperature) you must estimate consumption as specified in 
paragraphs (j)(3)(i)(A) and (B) of this section.
    (A) For each fluorinated GHG, you must either measure the 
temperature of the fluorinated GHG container(s) when the sampling 
periods begin and end and when containers are changed out, or measure 
the temperature of the fluorinated GHG container(s) every hour for the 
duration of the sampling period. Temperature measurements of the 
immediate vicinity of the containers (e.g., in the same room, near the 
containers) shall be considered temperature measurements of the 
containers.
    (B) Convert the sampling period-beginning, sampling period-ending, 
and container change-out pressures to masses using Equation I-25 of this 
subpart, with the appropriate Z value selected based upon the properties 
of the gas (e.g., the Z value yielded by the Redlich, Kwong, Soave 
equation of state with appropriate values for that gas). Apply the 
temperatures measured at or nearest to the beginning and end of the 
sampling period and to the time(s) when containers are changed out, as 
applicable. For each gas, the consumption during the sampling period is 
the difference between the masses of the containers of that gas at the 
beginning and at the end of the sampling period, summed across 
containers, including containers that are changed out.
    (ii) For each fluorinated GHG gas for which consumption is too low 
to be accurately measured during the sampling period using gas flow 
meters, scales, or pressure measurements as specified in paragraph 
(j)(3)(i) of this section, you must follow at least one of the 
procedures listed in paragraph (j)(3)(ii)(A) through (C) of this section 
to obtain a consumption measurement.
    (A) Draw the gas from a single gas container if it is normally 
supplied from multiple containers connected by a shared manifold.
    (B) Calculate consumption from pro-rated long-term consumption data 
(for example, calculate and use hourly consumption rates from monthly 
consumption data).
    (C) Increase the duration of the sampling period for consumption 
measurement beyond the minimum duration specified in Table I-9 of this 
subpart.
    (4) Emission test results. The results of an emission test must 
include the analysis of samples, number of test runs, the average 
emission factor for each fluorinated GHG measured, the analytical method 
used, calculation of emissions, the fluorinated GHGs consumed during the 
sampling period, an identification of the stack systems tested, and the 
fluorinated GHGs that were included in the test. The emissions test 
report must contain all information and data used to derive the fab-
specific emission factor.

[[Page 693]]

    (5) Emissions testing frequency. You must conduct emissions testing 
to develop fab-specific emission factors on a frequency according to the 
procedures in paragraph (j)(5)(i) or (ii) of this section.
    (i) Annual testing. You must conduct an annual emissions test for 
each stack system for which emissions testing is required under Sec. 
98.93(i)(3), unless you meet the criteria in paragraph (j)(5)(ii) of 
this section to skip annual testing. Each set of emissions testing for a 
stack system must be separated by a period of at least 2 months.
    (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.
    (B) The relative standard deviation for all single fluorinated GHGs 
that individually accounted for 5 percent or more of CO2e 
emissions were less than 20 percent.
    (6) Subsequent measurements. You must make an annual determination 
of each stack system's exemption status under Sec. 98.93(i)(2) by March 
31 each year. If a stack system that was previously not required to be 
tested per Sec. 98.93(i)(2), no longer meets the criteria in Sec. 
98.93(i)(2), you must conduct the emissions testing for the stack system 
during the current reporting and develop the fab-specific emission 
factor from the emissions testing.
    (7) Previous measurements. You may include the results of emissions 
testing conducted on or after January 1, 2011 for use in the relative 
standard deviation calculation in paragraph (j)(5)(ii) of this section 
if the previous results were determined using a method meeting the 
requirements in paragraph (j)(2) of this section. You may request 
approval to use results of emissions testing conducted between January 
1, 2011 and January 1, 2014 using a method that deviated from the 
requirements in paragraph (j)(2) of this section by adhering to the 
requirements in paragraphs (j)(7)(i) through (j)(7)(iv) of this section.
    (i) Notify the Administrator (or an authorized representative) of 
your intention to use the results of the previous emissions testing. You 
must include in the notification the data and results you intend to use 
for meeting either reporting or recordkeeping requirements, a 
description of the method, and any deviations from the requirements in 
paragraph (j)(2) of this section. Your description must include an 
explanation of how any deviations do not affect the quality of the data 
collected.
    (ii) The Administrator will review the information submitted under 
paragraph (j)(7)(i) and determine whether the results of the previous 
emissions testing are adequate and issue an approval or disapproval of 
the use of the results within 120 days of the date on

[[Page 694]]

which you submit the notification specified in paragraph (j)(7)(i) of 
this section.
    (iii) If the Administrator finds reasonable grounds to disapprove 
the results of the previous emissions testing, the Administrator may 
request that you provide additional information to support the use of 
the results of the previous emissions testing. Failure to respond to any 
request made by the Administrator does not affect the 120 day deadline 
specified in paragraph (j)(7)(ii) of this section.
    (iv) Neither the approval process nor the failure to obtain approval 
for the use of results from previous emissions testing shall abrogate 
your responsibility to comply with the requirements of this subpart.
    (8) Scenarios that require a stack system to be re-tested. By March 
31 of each reporting year, you must evaluate and determine whether any 
changes to your fab operations meet the criteria specified in paragraphs 
(j)(8)(i) through (vi) of this section. If any of the scenarios 
specified in paragraph (j)(8)(i) through (vi) of this section occur, you 
must perform a re-test of any applicable stack system, irrespective of 
whether you have met the criteria for less frequent testing in paragraph 
(j)(5)(ii) of this section, before the end of the year in which the 
evaluation was completed. You must adhere to the methods and procedures 
specified in Sec. 98.93(i)(3) for performing a stack system emissions 
test and calculating emissions. If you meet the criteria for less 
frequent testing in paragraph (j)(5)(ii), and you are required to 
perform a re-test as specified in paragraph (j)(8)(i) through (vi) of 
this section, the requirement to perform a re-test does not extend the 
date of the next scheduled test that was established prior to meeting 
the requirement to perform a re-test. If the criteria specified in 
paragraph (j)(5)(ii) of this section are not met using the results from 
the re-test and the two most recent stack tests, you must use the 
emission factors developed from the most recent testing to calculate 
emissions and resume annual testing. You may resume testing less 
frequently according to your original schedule if the criteria specified 
in paragraph (j)(5)(ii) of this section are met using the most recent 
three tests.
    (i) Annual consumption of a fluorinated GHG used during the most 
recent emissions test (expressed in CO2e) changes by more 
than 10 percent of the total annual fluorinated GHG consumption, 
relative to gas consumption in CO2e for that gas during the 
year of the most recent emissions test (for example, if the use of a 
single gas goes from 25 percent of CO2e to greater than 35 
percent of CO2e, this change would trigger a re-test).
    (ii) A change in the consumption of an intermittent low-use 
fluorinated GHG (as defined in Sec. 98.98) that was not used during the 
emissions test and not reflected in the fab-specific emission factor, 
such that it no longer meets the definition of an intermittent low-use 
fluorinated GHG.
    (iii) A decrease by more than 10 percent in the fraction of tools 
with abatement systems, compared to the number during the most recent 
emissions test.
    (iv) A change in the wafer size manufactured by the fab since the 
most recent emissions test.
    (v) A stack system that formerly met the criteria specified under 
Sec. 98.93(i)(2) for not being subject to testing no longer meets those 
criteria.
    (vi) If a fluorinated GHG being consumed in the reporting year was 
not being consumed during the stack test and does not meet the 
definition of intermittent, low-use fluorinated GHG in Sec. 98.98, then 
you must test the stack systems associated with the use of that 
fluorinated GHG at a time when that gas is in use as required in 
paragraph (j)(1)(iii) of this section.
    (k) You may request approval to use an alternative stack test method 
and procedure or to use an alternative method to determine abatement 
system destruction or removal efficiency by adhering to the requirements 
in paragraphs (k)(1) through (6) of this section. An alternative method 
is any method of sampling and analyzing for a fluorinated GHG or 
N2O, or the determination of parameters other than 
concentration, for example, flow measurements, that is not a method 
specified in this subpart and that has been demonstrated to the 
Administrator's

[[Page 695]]

satisfaction, using Method 301 in appendix A of part 63, to produce 
results adequate for the Administrator's determination that it may be 
used in place of a method specified elsewhere in this subpart.
    (1) You may use an alternative method from that specified in this 
subpart provided that you:
    (i) Notify the Administrator (or an authorized representative) of 
your intention to use an alternative method. You must include in the 
notification a site-specific test plan describing the alternative method 
and procedures (the alternative test plan), the range of test conditions 
over which the validation is intended to be applicable, and an 
alternative means of calculating the fab-level fluorinated GHG or 
N2O emissions or determining the abatement system destruction 
or removal efficiency if the Administrator denies the use of the results 
of the alternative method under paragraph (k)(2) or (3) of this section.
    (ii) Use Method 301 in appendix A of part 63 of this chapter to 
validate the alternative method. This may include the use of only 
portions of specific procedures of Method 301 if use of such procedures 
are sufficient to validate the alternative method; and
    (iii) Submit the results of the Method 301 validation process along 
with the notification of intention and the rationale for not using the 
specified method.
    (2) The Administrator will determine whether the validation of the 
proposed alternative method is adequate and issue an approval or 
disapproval of the alternative test plan within 120 days of the date on 
which you submit the notification and alternative test plan specified in 
paragraph (k)(1) of this section. If the Administrator approves the 
alternative test plan, you are authorized to use the alternative 
method(s) in place of the methods described in paragraph (f)(4)(i) of 
this section for measuring destruction or removal efficiency or 
paragraph (j) of this section for conducting the stack test, as 
applicable, taking into account the Administrator's comments on the 
alternative test plan. Notwithstanding the requirement in the preceding 
sentence, you may at any time prior to the Administrator's approval or 
disapproval proceed to conduct the stack test using the methods 
specified in paragraph (j) of this section or the destruction or removal 
efficiency determination specified in (f)(4)(i) of this section if you 
use a method specified in this subpart instead of the requested 
alternative. If an alternative test plan is not approved and you still 
want to use an alternative method, you must recommence the process to 
have an alternative test method approved starting with the notification 
of intent to use an alternative test method specified in paragraph 
(k)(1)(i) of this section.
    (3) You must report the results of stack testing or destruction or 
removal efficiency determination using the alternative method and 
procedure specified in the approved alternative test plan. You must 
include in your report for an alternative stack test method and for an 
alternative abatement system destruction or removal efficiency 
determination the information specified in paragraph (j)(4) of this 
section, including all methods, calculations and data used to determine 
the fluorinated GHG emission factor or the abatement system destruction 
or removal efficiency. The Administrator will review the results of the 
test using the alternative methods and procedure and then approve or 
deny the use of the results of the alternative test method and procedure 
no later than 120 days after they are submitted to EPA.
    (4) If the Administrator finds reasonable grounds to dispute the 
results obtained by an alternative method for the purposes of 
determining fluorinated GHG emissions or destruction or removal 
efficiency of an abatement system, the Administrator may require the use 
of another method specified in this subpart.
    (5) Once the Administrator has approved the use of the alternative 
method for the purposes of determining fluorinated GHG emissions for 
specific fluorinated GHGs and types of stack systems or abatement system 
destruction or removal efficiency, that method may be used at any other 
facility for the same fluorinated GHGs and types of stack systems, or 
fluorinated GHGs and abatement systems, if the

[[Page 696]]

approved conditions apply to that facility. In granting approval, the 
Administrator may limit the range of test conditions and emission 
characteristics for which that approval is granted and under which the 
alternative method may be used without seeking approval under paragraphs 
(k)(1) through (4) of this section. The Administrator will specify those 
limitations, if any, in the approval of the alternative method.
    (6) Neither the validation and approval process nor the failure to 
validate or obtain approval of an alternative method shall abrogate your 
responsibility to comply with the requirements of this subpart.

Sec. 98.95  Procedures for estimating missing data.

    (a) Except as provided in paragraph (b) of this section, a complete 
record of all measured parameters used in the fluorinated GHG and 
N2O emissions calculations in Sec. 98.93 and Sec. 98.94 is 
required.
    (b) If you use fluorinated heat transfer fluids at your facility and 
are missing data for one or more of the parameters in Equation I-16 of 
this subpart, you must estimate fluorinated heat transfer fluid 
emissions using the arithmetic average of the emission rates for the 
reporting year immediately preceding the period of missing data and the 
months immediately following the period of missing data. Alternatively, 
you may estimate missing information using records from the fluorinated 
heat transfer fluid supplier. You must document the method used and 
values used for all missing data values.

single consolidated 3-year report as long as the facility identifying 
information in Sec. 98.3(c)(1) and the certification statement in Sec. 
98.3(c)(9) is provided for each facility for which the consolidated 
report is submitted.
    (5) The Administrator will review the report received and determine 
whether it is necessary to update the default utilization rates and by-
product formation rates in Tables I-3, I-4, I-11, and I-12 of this 
subpart and default destruction or removal efficiency values in Table I-
16 of this subpart based on the following:
    (i) Whether the revised default utilization and by-product formation 
rates and destruction or removal efficiency values will result in a 
projected shift in emissions of 10 percent or greater.
    (ii) Whether new platforms, processes, or facilities that are not 
captured in current default utilization and by-product formation rates 
and destruction or removal efficiency values should be included in

will notify you of a determination whether it is necessary to update any 
default utilization and by-product formation rates and/or destruction or 
removal efficiency values. If the Administrator determines it is

Sec. 98.98  Definitions.

    Except as provided in this section, 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 takes precedence for the reporting requirements in this subpart.
    Abatement system means a device or equipment that is designed to 
destroy or remove fluorinated GHGs or N2O in exhaust streams 
from one or more electronics manufacturing production processes, or for 
which the destruction or removal efficiency for a fluorinated GHG or 
N2O has been properly measured according to the procedures 
under Sec. 98.94(f)(4), even if that abatement system is not designed 
to destroy or remove fluorinated GHGs or N2O. The device or 
equipment is only an abatement system for the individual fluorinated 
GHGs or N2O that it is designed to destroy or remove or for 
the individual fluorinated GHGs or N2O for which destruction 
or removal efficiencies were properly measured according to the 
procedures under Sec. 98.94(f)(4).
    Actual gas consumption means the quantity of gas used during wafer/
substrate processing over some period based on a measured change in gas 
container weight or gas container pressure or on a measured volume of 
gas.
    By-product formation means the creation of fluorinated GHGs during 
electronics manufacturing production processes or the creation of 
fluorinated GHGs by an abatement system. Where the procedures in Sec. 
98.93(a) are used to calculate annual emissions, by-product formation is 
the ratio of the mass of the by-product formed to the mass flow of the 
input gas. Where the procedures in Sec. 98.93(i) are used to calculate 
annual emissions, by-product formation is the ratio of the mass of the 
by-product formed to the total mass flow of all fluorinated GHG input 
gases.
    Chamber cleaning is a process type that consists of the process sub-
types defined in paragraphs (1) through (3) of this definition.
    (1) In situ plasma process sub-type consists of the cleaning of 
thin-film production chambers, after processing substrates, with a 
fluorinated GHG cleaning reagent that is dissociated into its cleaning 
constituents by a plasma generated inside the chamber where the film is 
produced.
    (2) Remote plasma process sub-type consists of the cleaning of thin-
film production chambers, after processing substrates, with a 
fluorinated GHG

[[Page 705]]

cleaning reagent dissociated by a remotely located plasma source.
    (3) In situ thermal process sub-type consists of the cleaning of 
thin-film production chambers, after processing substrates, with a 
fluorinated GHG cleaning reagent that is thermally dissociated into its 
cleaning constituents inside the chamber where thin films are produced.
    Controlled emissions means the quantity of emissions that are 
released to the atmosphere after application of an emission control 
device (e.g., abatement system).
    Destruction or removal efficiency (DRE) means the efficiency of an 
abatement system to destroy or remove fluorinated GHGs, N2O, 
or both. The destruction or removal efficiency is equal to one minus the 
ratio of the mass of all relevant GHGs exiting the abatement system to 
the mass of GHG entering the abatement system. When GHGs are formed in 
an abatement system, destruction or removal efficiency is expressed as 
one minus the ratio of amounts of exiting GHGs to the amounts entering 
the system in units of CO2-equivalents (CO2e).
    Fab means the portion of an electronics manufacturing facility 
located in a separate physical structure that began manufacturing on a 
certain date.
    Fluorinated heat transfer fluids means fluorinated GHGs used for 
temperature control, device testing, cleaning substrate surfaces and 
other parts, and soldering in certain types of electronics manufacturing 
production processes. Fluorinated heat transfer fluids do not include 
fluorinated GHGs used as lubricants or surfactants. For fluorinated heat 
transfer fluids under this subpart I, 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 used in the electronics manufacturing sector include, but are not 
limited to, perfluoropolyethers, perfluoroalkanes, perfluoroethers, 
tertiary perfluoroamines, and perfluorocyclic ethers.
    Fully fluorinated GHGs means fluorinated GHGs that contain only 
single bonds and in which all available valence locations are filled by 
fluorine atoms. This includes, but is not limited to, saturated 
perfluorocarbons, SF6, NF3, 
SF5CF3, C4F8O, fully 
fluorinated linear, branched, and cyclic alkanes, fully fluorinated 
ethers, fully fluorinated tertiary amines, fully fluorinated 
aminoethers, and perfluoropolyethers.
    Gas utilization means the fraction of input N2O or 
fluorinated GHG converted to other substances during the etching, 
deposition, and/or wafer and chamber cleaning processes. Gas utilization 
is expressed as a rate or factor for specific electronics manufacturing 
process sub-types or process types.
    Heel means the amount of gas that remains in a gas container after 
it is discharged or off-loaded; heel may vary by container type.
    Input gas means a fluorinated GHG or N2O used in one of 
the processes described in Sec. 98.90(a)(1) through (4)
    Intermittent low-use fluorinated GHG, for the purposes of 
determining fluorinated GHG emissions using the stack testing method, 
means a fluorinated GHG that meets all of the following:
    (1) The fluorinated GHG is used by the fab but is not used during 
the period of stack testing for the fab/stack system.
    (2) The emissions of the fluorinated GHG, estimated using the 
methods in Sec. 98.93(i)(4) do not constitute more than 5 percent of 
the total fluorinated GHG emissions from the fab on a CO2e 
basis.
    (3) The sum of the emissions of all fluorinated GHGs that are 
considered intermittent low use gases does not exceed 10,000 metric tons 
CO2e for the fab for that year, as calculated using the 
procedures specified in Sec. 98.93(i)(1) of this subpart.
    (4) The fluorinated GHG is not an expected or possible by-product 
identified in Table I-17 of this subpart.
    Maximum substrate starts means for the purposes of Equation I-5 of 
this subpart, the maximum quantity of substrates, expressed as surface 
area, that could be started each month during a reporting year based on 
the equipment installed in that facility and assuming that the installed 
equipment were fully utilized. Manufacturing equipment is considered 
installed when it is on the

[[Page 706]]

manufacturing floor and connected to required utilities.
    Modeled gas consumed means the quantity of gas used during wafer/
substrate processing over some period based on a verified facility-
specific engineering model used to apportion gas consumption.
    Nameplate capacity means the full and proper charge of chemical 
specified by the equipment manufacturer to achieve the equipment's 
specified performance. The nameplate capacity is typically indicated on 
the equipment's nameplate; it is not necessarily the actual charge, 
which may be influenced by leakage and other emissions.
    Operational mode means the time in which an abatement system is 
properly installed, maintained, and operated according to the site 
maintenance plan for abatement systems as required in Sec. 98.94(f)(1) 
and defined in Sec. 98.97(d)(9). This includes being properly operated 
within the range of parameters as specified in the site maintenance plan 
for abatement systems.
    Plasma etching is a process type that consists of any production 
process using fluorinated GHG reagents to selectively remove materials 
from a substrate during electronics manufacturing. The materials removed 
may include SiO2, SiOX-based or fully organic-
based thin-film material, SiN, SiON, Si3N4, SiC, 
SiCO, SiCN, etc. (represented by the general chemical formula, 
SiwOXNyXz where w, x, y and 
z are zero or integers and X may be some other element such as carbon), 
substrate, or metal films (such as aluminum or tungsten).
    Process sub-type is a set of similar manufacturing steps, more 
closely related within a broad process type. For example, the chamber 
cleaning process type includes in-situ plasma chamber cleaning, remote 
plasma chamber cleaning, and in-situ thermal chamber cleaning sub-types.
    Process types are broad groups of manufacturing steps used at a 
facility associated with substrate (e.g., wafer) processing during 
device manufacture for which fluorinated GHG emissions and fluorinated 
GHG consumption is calculated and reported. The process types are Plasma 
etching/Wafer Cleaning and Chamber cleaning.
    Properly measured destruction or removal efficiency means 
destruction or removal efficiencies measured in accordance with EPA 430-
R-10-003 (incorporated by reference, see Sec. 98.7), and, if 
applicable, Appendix A to this subpart, or by an alternative method 
approved by the Administrator as specified in Sec. 98.94(k).
    The Random Sampling Abatement System Testing Program (RSASTP) means 
the required frequency for measuring the destruction or removal 
efficiencies of abatement systems in order to apply properly measured 
destruction or removal efficiencies to report controlled emissions.
    Redundant abatement systems means a system that is specifically 
designed, installed and operated for the purpose of destroying 
fluorinated GHGs and N2O gases, or for which the destruction 
or removal efficiency for a fluorinated GHG or N2O has been 
properly measured according to the procedures under Sec. 98.94(f)(4), 
and that is used as a backup to the main fluorinated GHGs and 
N2O abatement system during those times when the main system 
is not functioning or operating in accordance with design and operating 
specifications.
    Repeatable means that the variables used in the formulas for the 
facility's engineering model for gas apportioning factors are based on 
observable and measurable quantities that govern gas consumption rather 
than engineering judgment about those quantities or gas consumption.
    Representative operating levels means (for purposes of verification 
of the apportionment model or for determining the appropriate conditions 
for stack testing) operating the fab, in terms of substrate starts for 
the period of testing or monitoring, at no less than 50 percent of 
installed production capacity or no less than 70 percent of the average 
production rate for the reporting year, where production rate for the 
reporting year is represented in average monthly substrate starts. For 
the purposes of stack testing, the period for determining the 
representative operating level must be the period ending on the same 
date on which testing is concluded.

[[Page 707]]

    Stack system means one or more stacks that are connected by a common 
header or manifold, through which a fluorinated GHG-containing gas 
stream originating from one or more fab processes is, or has the 
potential to be, released to the atmosphere. For purposes of this 
subpart, stack systems do not include emergency vents or bypass stacks 
through which emissions are not usually vented under typical operating 
conditions.
    Trigger point for change out means the residual weight or pressure 
of a gas container type that a facility uses as an indicator that 
operators need to change out that gas container with a full container. 
The trigger point is not the actual residual weight or pressure of the 
gas remaining in the cylinder that has been replaced.
    Unabated emissions means a gas stream containing fluorinated GHG or 
N2O that has exited the process, but which has not yet been 
introduced into an abatement system to reduce the mass of fluorinated 
GHG or N2O in the stream. If the emissions from the process 
are not routed to an abatement system, or are routed to an abatement 
device that is not in an operational mode, unabated emissions are those 
fluorinated GHG or N2O released to the atmosphere.
    Uptime means the ratio of the total time during which the abatement 
system is in an operational mode, to the total time during which 
production process tool(s) connected to that abatement system are 
normally in operation.
    Wafer cleaning is a process type that consists of any production 
process using fluorinated GHG reagents to clean wafers at any step 
during production.
    Wafer passes is a count of the number of times a wafer substrate is 
processed in a specific process sub-type, or type. The total number of 
wafer passes over a reporting year is the number of wafer passes per 
tool multiplied by the number of operational process tools in use during 
the reporting year.
    Wafer starts means the number of fresh wafers that are introduced 
into the fabrication sequence each month. It includes test wafers, which 
means wafers that are exposed to all of the conditions of process 
characterization, including but not limited to actual etch conditions or 
actual film deposition conditions.

[78 FR 68234, Nov. 13, 2013]



  Sec. Appendix A to Subpart I of Part 98--Alternative Procedures for 
     Measuring Point-of-Use Abatement Device Destruction or Removal 
                               Efficiency

    If you are measuring destruction or removal efficiency of a point-
of-use abatement device according to EPA 430-R-10-003 (incorporated by 
reference, see Sec. 98.7) as specified in Sec. 98.94(f)(4), you may 
follow the alternative procedures specified in paragraphs (a) through 
(c) of this appendix.
    (a) In place of the Quadrupole Mass Spectrometry protocol 
requirements specified in section 2.2.4 of EPA 430-R-10-003 
(incorporated by reference, see Sec. 98.7), you must conduct mass 
spectrometry testing in accordance with the provisions in paragraph 
(a)(1) through (a)(15) of this appendix.
    (1) Detection limits. The mass spectrometer chosen for this 
application must have the necessary sensitivity to detect the selected 
effluent species at or below the maximum field detection limits 
specified in Table 3 of section 2.2.7 of EPA 430-R-10-003 (incorporated 
by reference, see Sec. 98.7).
    (2) Sampling location. The sample at the inlet of the point-of-use 
abatement device must be taken downstream of the process tool and pump 
package. The sample exhaust must be vented back into the corrosive house 
ventilation system at a point downstream of the sample inlet location.
    (3) Sampling conditions. For etch processes, destruction or removal 
efficiencies must be determined while etching a substrate (product, 
dummy, or test). For chemical vapor deposition processes, destruction or 
removal efficiencies must be determined during a chamber clean after 
deposition (destruction or removal efficiencies must not be determined 
in a clean chamber). All sampling must be performed non-intrusively 
during wafer processing. Samples must be drawn

[[Page 721]]

through the mass spectrometer source by an external sample pump. Because 
of the volatility, vapor pressure, stability and inertness of 
CF4, C2F6, C3F8, 
CHF3, NF3, and SF6, the sample lines do 
not need to be heated.
    (4) Mass spectrometer parameters. The specific mass spectrometer 
operating conditions such as electron energy, secondary electron 
multiplier voltage, emission current, and ion focusing voltage must be 
selected according to the specifications provided by the mass 
spectrometer manufacturer, the mass spectrometer system manual, basic 
mass spectrometer textbook, or other such sources. The mass spectrometer 
responses to each of the target analytes must all be calibrated under 
the same mass spectrometer operating conditions.
    (5) Flow rates. A sample flow rate of 0.5-1.5 standard liters per 
minute (slm) must be drawn from the process tool exhaust stream under 
study.
    (6) Sample frequency. The mass spectrometer sampling frequency for 
etch processes must be in the range of 0.5 to 1 cycles per second, and 
for chemical vapor deposition processes must be in the range of 0.25 to 
0.5 cycles per second. As an alternative you may use the sampling 
frequencies specified in section 2.2.4 of EPA 430-R-10-003 (incorporated 
by reference, see Sec. 98.7).
    (7) Dynamic dilution calibration parameters. The quadrupole mass 
spectrometer must be calibrated for both mass location and response to 
analytes. A dynamic dilution calibration system may be used to perform 
both types of mass spectrometer system calibrations using two mass flow 
controllers. Use one mass flow controller to regulate the flow rate of 
the standard component used to calibrate the system and the second mass 
flow controller to regulate the amount of diluent gas used to mix with 
the standard to generate the calibration curve for each compound of 
interest. The mass flow controller must be calibrated using the single 
component gas being used with them, for example, nitrogen 
(N2) for the diluent. A mass flow controller used with 
calibration mixtures must be calibrated with the calibration mixture 
balance gas (for example, N2 or He) if the analyte components 
are 2 percent or less of the volume of the sample. All calibration 
mixtures must be National Institute of Standards and Technology 
Traceable gases or equivalent. They must be calibrated over their range 
of use and must be operated in their experimentally determined dynamic 
linear range. If compressed gas standards cannot be brought into the 
fab, metered gas flows of target compounds into the process chamber, 
under no thermal or plasma conditions and with no wafer(s) present, and 
with no process emissions from other tools contributing to the sample 
location, must then be performed throughout the appropriate 
concentration ranges to derive calibration curves for the subsequent 
destruction or removal efficiency tests.
    (8) Mass location calibration. A mixture containing 1 percent He, 
Ar, Kr, and Xe in a balance gas of nitrogen must be used to assure the 
alignment of the quadrupole mass filter (see EPA Method 205 at 40 CFR 
part 51, appendix M as reference). The mass spectrometer must be chosen 
so that the mass range is sufficient to detect the predominant peaks of 
the components under study.
    (9) Quadrupole mass spectrometer response calibration. A calibration 
curve must be generated for each compound of interest.
    (10) Calibration frequency. The mass spectrometer must be calibrated 
at the start of testing a given process. The calibration must be checked 
at the end of testing.
    (11) Calibration range. The mass spectrometer must be calibrated 
over the expected concentration range of analytes using a minimum of 
five concentrations including a zero. The zero point is defined as 
diluent containing no added analyte.
    (12) Operating procedures. You must follow the operating procedures 
specified in paragraphs (a)(12)(i) through (v) of this appendix.
    (i) You must perform a qualitative mass calibration by running a 
standard (or by flowing chamber gases under non-process conditions) 
containing stable components such as Ar, Kr, and Xe that provide 
predominant signals at m/e values distributed throughout the mass range 
to be used. You must adjust the quadrupole mass filter as needed to 
align with the inert gas fragments.
    (ii) You must quantitatively calibrate the quadrupole mass 
spectrometer for each analyte of interest. The analyte concentrations 
during calibration must include the expected concentrations in the 
process effluent. The calibration must be performed under the same 
operating conditions, such as inlet pressure, as when sampling process 
exhaust. If the calibration inlet pressure differs from the sampling 
inlet pressure then the relationship between inlet pressure and 
quadrupole mass spectrometer signal response must be empirically 
determined and applied to correct for any differences between 
calibration and process emissions monitoring data.
    (iii) To determine the response time of the instrument to changes in 
a process, a process gas such as C2F6 must be 
turned on at the process tool for a fixed period of time (for example, 
20 seconds), after which the gas is shut off. The sample flow rate 
through the system must be adjusted so that the signal increases to a 
constant concentration within a few seconds and decreases to background 
levels also within a few seconds.
    (iv) You must sample the process effluent through the quadrupole 
mass spectrometer and acquire data for the required amount of time to 
track the process, as determined in paragraph (a)(12)(iii) of this 
appendix. You

[[Page 722]]

must set the sample frequency to monitor the changes in the process as 
specified in paragraph (a)(6) of this appendix. You must repeat this for 
at least five substrates on the same process and calculate the average 
and standard deviation of the analyte concentration.
    (v) You must repeat the quantitative calibration at the conclusion 
of sampling to identify any drifts in quadrupole mass spectrometer 
sensitivity. If drift is observed, you must use an internal standard to 
correct for changes in sensitivity.
    (13) Sample analysis. To determine the concentration of a specific 
component in the sample, you must divide the ion intensity of the sample 
response by the calibrated response factor for each component.
    (14) Deconvolution of interfering peaks. The effects of interfering 
peaks must be deconvoluted from the mass spectra for each target 
analyte.
    (15) Calculations. Plot ion intensity versus analyte concentration 
for a given compound obtained when calibrating the analytical system. 
Determine the slope and intercept for each calibrated species to obtain 
response factors with which to calculate concentrations in the sample. 
For an acceptable calibration, the R\2\ value of the calibration curve 
must be at least 0.98.
    (b) In place of the Fourier Transform Infrared Spectroscopy protocol 
requirements specified in section 2.2.4 of EPA 430-R-10-003 
(incorporated by reference, see Sec. 98.7), you may conduct Fourier 
Transform Infrared Spectroscopy testing in accordance with the 
provisions in paragraph (b)(1) through (17) of this appendix, including 
the laboratory study phase described in paragraphs (b)(1) through (7), 
and the field study phase described in paragraphs (b)(8) through (17) of 
this appendix.
    (1) Conformance with provisions associated with the Calibration 
Transfer Standard. This procedure calls for the use of a calibration 
transfer standard in a number of instances. The use of a calibration 
transfer standard is necessary to validate optical pathlength and 
detector response for spectrometers where cell temperature, cell 
pressure, and cell optical pathlength are potentially variable. For 
fixed pathlength spectrometers capable of controlling cell temperature 
and pressure to within 10 percent of a desired set 
point, the use of a calibration transfer standard, as described in 
paragraphs (b)(2) to (17) this appendix is not required.
    (2) Defining spectroscopic conditions. Define a set of spectroscopic 
conditions under which the field studies and subsequent field 
applications are to be carried out. These include the minimum 
instrumental line-width, spectrometer wave number range, sample gas 
temperature, sample gas pressure, absorption pathlength, maximum 
sampling system volume (including the absorption cell), minimum sample 
flow rate, and maximum allowable time between consecutive infrared 
analyses of the effluent.
    (3) Criteria for reference spectral libraries. On the basis of 
previous emissions test results and/or process knowledge (including the 
documentation of results of any initial and subsequent tests, and the 
final reports required in Sec. 98.97(d)(4)(i)), estimate the maximum 
concentrations of all of the analytes in the effluent and their minimum 
concentrations of interest (those concentrations below which the 
measurement of the compounds is of no importance to the analysis). 
Values between the maximum expected concentration and the minimum 
concentration of interest are referred to below as the ``expected 
concentration range.'' A minimum of three reference spectra is 
sufficient for a small expected concentration range (e.g., a difference 
of 30 percent of the range between the low and high ends of the range), 
but a minimum of four spectra are needed where the range is greater, 
especially for concentration ranges that may differ by orders of 
magnitude. If the measurement method is not linear then multiple linear 
ranges may be necessary. If this approach is adopted, then linear range 
must be demonstrated to pass the required quality control. When the set 
of spectra is ordered according to absorbance, the absorbance levels of 
adjacent reference spectra should not differ by more than a factor of 
six. Reference spectra for each analyte should be available at 
absorbance levels that bracket the analyte's expected concentration 
range; minimally, the spectrum whose absorbance exceeds each analyte's 
expected maximum concentration or is within 30 percent of it must be 
available. The reference spectra must be collected at or near the same 
temperature and pressure at which the sample is to be analyzed under. 
The gas sample pressure and temperature must be continuously monitored 
during field testing and you must correct for differences in temperature 
and pressure between the sample and reference spectra. Differences 
between the sample and reference spectra conditions must not exceed 50 
percent for pressure and 40 [deg]C for temperature.
    (4) Spectra without reference libraries. If reference spectral 
libraries meeting the criteria in paragraph (b)(3) of this appendix do 
not exist for all the analytes and interferants or cannot be accurately 
generated from existing libraries exhibiting lower minimum instrumental 
line-width values than those proposed for the testing, prepare the 
required spectra according to the procedures specified in paragraphs 
(b)(4)(i) and (ii) of this appendix.
    (i) Reference spectra at the same absorbance level (to within 10 
percent) of independently prepared samples must be recorded. The 
reference samples must be prepared from neat forms of the analyte or 
from gas

[[Page 723]]

standards of the highest quality commonly available from commercial 
sources. Either barometric or volumetric methods may be used to dilute 
the reference samples to the required concentrations, and the equipment 
used must be independently calibrated to ensure suitable accuracy. 
Dynamic and static reference sample preparation methods are acceptable, 
but dynamic preparations must be used for reactive analytes. Any well 
characterized absorption pathlength may be employed in recording 
reference spectra, but the temperature and pressure of the reference 
samples should match as closely as possible those of the proposed 
spectroscopic conditions.
    (ii) If a mercury cadmium telluride or other potentially non-linear 
detector (i.e., a detector whose response vs. total infrared power is 
not a linear function over the range of responses employed) is used for 
recording the reference spectra, you must correct for the effects of 
this type of response on the resulting concentration values. As needed, 
spectra of a calibration transfer standard must be recorded with the 
laboratory spectrometer system to verify the absorption pathlength and 
other aspects of the system performance. All reference spectral data 
must be recorded in interferometric form and stored digitally.
    (5) Sampling system preparation. Construct a sampling system 
suitable for delivering the proposed sample flow rate from the effluent 
source to the infrared absorption cell. For the compounds of interest, 
the surfaces of the system exposed to the effluent stream may need to be 
stainless steel or Teflon; because of the potential for generation of 
inorganic automated gases, glass surfaces within the sampling system and 
absorption cell may need to be Teflon-coated. The sampling system should 
be able to deliver a volume of sample that results in a necessary 
response time.
    (6) Preliminary analytical routines. For the proposed absorption 
pathlength to be used in actual emissions testing, you must prepare an 
analysis method containing of all the effluent compounds at their 
expected maximum concentrations plus the field calibration transfer 
standard compound at 20 percent of its full concentration as needed.
    (7) Documentation. The laboratory techniques used to generate 
reference spectra and to convert sample spectral information to compound 
concentrations must be documented. The required level of detail for the 
documentation is that which allows an independent analyst to reproduce 
the results from the documentation and the stored interferometric data.
    (8) Spectroscopic system performance. The performance of the 
proposed spectroscopic system, sampling system, and analytical method 
must be rigorously examined during and after a field study. Several 
iterations of the analysis method may need to be applied depending on 
observed concentrations, absorbance intensities, and interferences. 
During the field study, all the sampling and analytical procedures 
envisioned for future field applications must be documented. Additional 
procedures not required during routine field applications, notably 
dynamic spiking studies of the analyte gases, may be performed during 
the field study. These additional procedures need to be performed only 
once if the results are acceptable and if the effluent sources in future 
field applications prove suitably similar to those chosen for the field 
study. If changes in the effluent sources in future applications are 
noted and require substantial changes to the analytical equipment and/or 
conditions, a separate field study must be performed for the new set of 
effluent source conditions. All data recorded during the study must be 
retained and documented, and all spectral information must be 
permanently stored in interferometric form.
    (9) System installation. The spectroscopic and sampling sub-systems 
must be assembled and installed according to the manufacturers' 
recommendations. For the field study, the length of the sample lines 
used must not be less than the maximum length envisioned for future 
field applications. The system must be given sufficient time to 
stabilize before testing begins.
    (10) Pre-Test calibration. Record a suitable background spectrum 
using pure nitrogen gas; alternatively, if the analytes of interest are 
in a sample matrix consistent with ambient air, it is beneficial to use 
an ambient air background to control interferences from water and carbon 
dioxide. For variable pathlength Fourier Transform Infrared 
Spectrometers, introduce a sample of the calibration transfer standard 
gas directly into the absorption cell at the expected sample pressure 
and record its absorbance spectrum (the ``initial field calibration 
transfer standard spectrum''). Compare it to the laboratory calibration 
transfer standard spectra to determine the effective absorption 
pathlength. If possible, record spectra of field calibration gas 
standards (single component standards of the analyte compounds) and 
determine their concentrations using the reference spectra and 
analytical routines developed in paragraphs (b)(2) through (7) of this 
appendix; these spectra may be used instead of the reference spectra in 
actual concentration and uncertainty calculations.
    (11) Deriving the calibration transfer standard gas from tool 
chamber gases. The calibration transfer standard gas may be derived by 
flowing appropriate semiconductor tool chamber gases under non-process 
conditions (no thermal or plasma conditions and with no wafer(s) 
present) if compressed gas standards cannot be brought on-site.

[[Page 724]]

    (12) Reactivity and response time checks. While sampling ambient air 
and continuously recording absorbance spectra, suddenly replace the 
ambient air flow with calibration transfer standard gas introduced as 
close as possible to the probe tip. Examine the subsequent spectra to 
determine whether the flow rate and sample volume allow the system to 
respond quickly enough to changes in the sampled gas. Should a corrosive 
or reactive gas be of interest in the sample matrix it would be 
beneficial to determine the reactivity in a similar fashion, if 
practical. Examine the subsequent spectra to ensure that the 
reactivities of the analytes with the exposed surfaces of the sampling 
system do not limit the time response of the analytical system. If a 
pressure correction routine is not automated, monitor the absorption 
cell temperature and pressure; verify that the (absolute) pressure 
remains within 2 percent of the pressure specified in the proposed 
system conditions.
    (13) Analyte spiking. Analyte spiking must be performed. While 
sampling actual source effluent, introduce a known flow rate of 
calibration transfer standard gas into the sample stream as close as 
possible to the probe tip or between the probe and extraction line. 
Measure and monitor the total sample flow rate, and adjust the spike 
flow rate until it represents 10 percent to 20 percent of the total flow 
rate. After waiting until at least four absorption cell volumes have 
been sampled, record four spectra of the spiked effluent, terminate the 
calibration transfer standard spike flow, pause until at least four cell 
volumes are sampled, and then record four (unspiked) spectra. Repeat 
this process until 12 spiked and 12 unspiked spectra have been obtained. 
If a pressure correction routine is not automated, monitor the 
absorption cell temperature and pressure; verify that the pressure 
remains within 2 percent of the pressure specified in the proposed 
system conditions. Calculate the expected calibration transfer standard 
compound concentrations in the spectra and compare them to the values 
observed in the spectrum. This procedure is best performed using a 
spectroscopic tracer to calculate dilution (as opposed to measured flow 
rates) of the injected calibration transfer standard (or analyte). The 
spectroscopic tracer should be a component not in the gas matrix that is 
easily detectable and maintains a linear absorbance over a large 
concentration range. Repeat this spiking process with all effluent 
compounds that are potentially reactive with either the sampling system 
components or with other effluent compounds. The gas spike is delivered 
by a mass flow controller, and the expected concentration of analyte of 
interest (AOITheoretical) is calculated as follows:
[GRAPHIC] [TIFF OMITTED] TR13NO13.028

Where:

AOITheoretical = Theoretical analyte of interest concentration (parts 
          per million (ppm)).
Tracersample = Tracer concentration (ppm) as seen by the Fourier 
          Transform Infrared Spectrometer during spiking.
Tracercylinder = The concentration (ppm) of tracer recorded during 
          direct injection of the cylinder to the Fourier Transform 
          Infrared Spectrometer cell.
AOIcylinder = The supplier-certified concentration (ppm) of the analyte 
          of interest gas standard.
AOInative = The native AOI concentration (ppm) of the effluent during 
          stable conditions.

    (14) Post-test calibration. At the end of a sampling run and at the 
end of the field study, record the spectrum of the calibration transfer 
standard gas. The resulting ``final field calibration transfer standard 
spectrum'' must be compared to the initial field calibration transfer 
standard spectrum to verify suitable stability of the spectroscopic 
system throughout the course of the field study.
    (15) Amendment of analytical routines. The presence of unanticipated 
interferant compounds and/or the observation of compounds at 
concentrations outside their expected concentration ranges may 
necessitate the repetition of portions of the procedures in paragraphs 
(b)(2) through (14) of this appendix. Such amendments are allowable 
before final analysis of the data, but must be represented in the 
documentation required in paragraph (b)(16) of this appendix.
    (16) Documentation. The sampling and spiking techniques used to 
generate the field study spectra and to convert sample spectral 
information to concentrations must be documented at a level of detail 
that allows an independent analyst to reproduce the results from the 
documentation and the stored interferometric data.

[[Page 725]]

    (17) Method application. When the required laboratory and field 
studies have been completed and if the results indicate a suitable 
degree of accuracy, the methods developed may be applied to practical 
field measurement tasks. During field applications, the procedures 
demonstrated in the field study specified in paragraphs (b)(8) through 
(16) of this appendix must be adhered to as closely as possible, with 
the following exceptions specified in paragraphs (b)(17)(i) through 
(iii) of this appendix:
    (i) The sampling lines employed should be as short as practically 
possible and not longer than those used in the field study.
    (ii) Analyte spiking and reactivity checks are required after the 
installation of or major repair to the sampling system or major change 
in sample matrix. In these cases, perform three spiked/unspiked samples 
with calibration transfer standard or a surrogate analyte on a daily 
basis if time permits and gas standards are easy to obtain and get on-
site.
    (iii) Sampling and other operational data must be recorded and 
documented as during the field study, but only the interferometric data 
needed to sufficiently reproduce actual test and spiking data must be 
stored permanently. The format of this data does not need to be 
interferograms but may be absorbance spectra or single beams.
    (c) When using the flow and dilution measurement protocol specified 
in section 2.2.6 of EPA 430-R-10-003 (incorporated by reference, see 
Sec. 98.7), you may determine point-of-use abatement device total 
volume flow with the modifications specified in paragraphs (c)(1) 
through (3) of this appendix.
    (1) You may introduce the non-reactive, non-native gas used for 
determining total volume flow and dilution across the point-of-use 
abatement device at a location in the exhaust of the point-of-use 
abatement device. For abatement systems operating in a mode where 
specific F-GHG are not readily abated, you may introduce the non-
reactive, non-native gas used for determining total volume flow and 
dilution across the point-of-use abatement device prior to the point-of-
use abatement system; in this case, the tracer must be more difficult to 
destroy than the target compounds being measured based on the thermal 
stability of the tracer and target.
    (2) You may select a location for downstream non-reactive, non-
native gas analysis that complies with the requirements in this 
paragraph (c)(2) of this appendix. The sampling location should be 
traversed with the sampling probe measuring the non-reactive, non-native 
gas concentrations to ensure homogeneity of the non-reactive gas and 
point-of-use abatement device effluent (i.e., stratification test). To 
test for stratification, measure the non-reactive, non-native gas 
concentrations at three points on a line passing through the centroidal 
area. Space the three points at 16.7, 50.0, and 83.3 percent of the 
measurement line. Sample for a minimum of twice the system response 
time, determined according to paragraph (c)(3) of this appendix, at each 
traverse point. Calculate the individual point and mean non-reactive, 
non-native gas concentrations. If the non-reactive, non-native gas 
concentration at each traverse point differs from the mean concentration 
for all traverse points by no more than 5.0 
percent of the mean concentration, the gas stream is considered 
unstratified and you may collect samples from a single point that most 
closely matches the mean. If the 5.0 percent criterion is not met, but 
the concentration at each traverse point differs from the mean 
concentration for all traverse points by no more than 10.0 percent of the mean, you may take samples from two 
points and use the average of the two measurements. Space the two points 
at 16.7, 50.0, or 83.3 percent of the measurement line. If the 
concentration at each traverse point differs from the mean concentration 
for all traverse points by more than 10.0 percent 
of the mean but less than 20.0 percent, take samples from three points 
at 16.7, 50.0, and 83.3 percent of the measurement line and use the 
average of the three measurements. If the gas stream is found to be 
stratified because the 20.0 percent criterion for a 3-point test is not 
met, locate and sample the non-reactive, non-native gas from traverse 
points for the test in accordance with Sections 11.2 and 11.3 of EPA 
Method 1 in 40 CFR part 60, Appendix A-1. A minimum of 40 non-reactive 
gas concentration measurements will be collected at three to five 
different injected non-reactive gas flow rates for determination of 
point-of-use abatement device effluent flow. The total volume flow of 
the point-of-use abatement device exhaust will be calculated consistent 
with the EPA 430-R-10-003 (incorporated by reference, see Sec. 98.7) 
Equations 1 through 7.
    (3) You must determine the measurement system response time 
according to paragraphs (c)(3)(i) through (iii) of this appendix.
    (i) Before sampling begins, introduce ambient air at the probe 
upstream of all sample condition components in system calibration mode. 
Record the time it takes for the measured concentration of a selected 
compound (for example, carbon dioxide) to reach steady state.
    (ii) Introduce nitrogen in the system calibration mode and record 
the time required for the concentration of the selected compound to 
reach steady state.
    (iii) Observe the time required to achieve 95 percent of a stable 
response for both nitrogen and ambient air. The longer interval is the 
measurement system response time.

Sec. 98.114  Monitoring and QA/QC requirements.

    If you determine annual process CO2 emissions using the 
carbon mass balance procedure in Sec. 98.113(b)(2), you must meet the 
requirements specified in paragraphs (a) and (b) of this section.
    (a) Determine the annual mass for each material used for the 
calculations of annual process CO2 emissions using Equation 
K-1 of this subpart by summing the monthly mass for the material 
determined for each month of the calendar year. The monthly mass may be 
determined using plant instruments used for accounting purposes, 
including either direct measurement of the quantity of the material 
placed in the unit or by calculations using process operating 
information.

of the material inputs and outputs each year. The carbon content of the 
material must be analyzed at least annually using the standard methods

Sec. 98.115  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations in Sec. 98.113 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 the paragraphs (a) and (b) of this section. 
You must document and keep records of the procedures used for all such 
estimates.
    (a) If you determine CO2 emissions for the EAFs at your 
facility using the carbon mass balance procedure in Sec. 98.113(b), 100 
percent data availability is required for the carbon content of the 
input and output materials. You must repeat the test for average carbon 
contents of inputs according to the procedures in Sec. 98.114(b) if 
data are missing.
    (b) For missing records of the monthly mass of carbon-containing 
inputs and outputs, the substitute data value must be based on the best 
available estimate of the mass of the inputs and outputs from on all 
available process data or data used for accounting purposes, such as 
purchase records.
    (c) If you are required to calculate CH4 emissions for an 
EAF at your facility as specified in Sec. 98.113(d), the estimate is 
based an annual quantity of certain alloy products, so 100 percent data 
availability is required.



Sec. 98.116  Data reporting requirements.

    In addition to the information required by Sec. 98.3(c), each 
annual report must contain the information specified in paragraphs (a)

98.110, from each EAF (tons).
    (c) Total number of EAFs at facility used for production of 
ferroalloy products.

    (e) If a CEMS is not used to measure CO2 process 
emissions, and the carbon mass balance procedure is used to determine 
CO2 emissions according to the requirements in Sec. 
98.113(b), then you must report the following information specified in 
paragraphs (e)(1) through (e)(7) of this section.

                  Subpart L_Fluorinated Gas Production

    Source: 75 FR 74831, Dec. 1, 2010, unless otherwise noted.



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 of a CFC or HCFC 
as an isolated intermediate 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, the creation of intermediates that are created 
and transformed in a single process with no storage of the 
intermediates, or the creation of fluorinated GHGs that are released or 
destroyed at the production facility before the production measurement 
in Sec. 98.414(a).



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). 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.

[[Page 732]]



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) Emissions from production and transformation processes, process 
level. You must report, for each fluorinated GHG group, the total GWP-
weighted mass of all fluorinated GHGs in that group (in metric tons 
CO2e) emitted from:
    (1) Each fluorinated gas production process.
    (2) Each fluorinated gas transformation process that is not part of 
a fluorinated gas production process and where no fluorinated GHG 
reactant is produced at another facility.
    (3) Each fluorinated gas transformation process that is not part of 
a fluorinated gas production process and where one or more fluorinated 
GHG reactants are produced at another facility.
    (d) Emissions from production and transformation processes, facility 
level, multiple products. If your facility produces more than one 
fluorinated gas product, you must report the emissions (in metric tons) 
from production and transformation processes, totaled across the 
facility as a whole, of each fluorinated GHG that is emitted in 
quantities of 1,000 metric tons of CO2e or more from 
production or transformation processes, totaled across the facility as a 
whole. Aggregate and report emissions of all other fluorinated GHGs from 
production and transformation processes by fluorinated GHG group for the 
facility as a whole, in metric tons of CO2e.
    (e) Emissions from production and transformation processes, facility 
level, one product only. If your facility produces only one fluorinated 
gas product, aggregate and report the GWP-weighted emissions from 
production and transformation processes of fluorinated GHGs by 
fluorinated GHG group for the facility as a whole, in metric tons 
CO2e, with the following exception: Where emissions consist 
of a major fluorinated GHG constituent of a fluorinated gas product, and 
the product is sold or transferred to another person, report the total 
mass of each fluorinated GHG that is emitted from production and 
transformation processes and that is a major fluorinated GHG constituent 
of the product (in metric tons).
    (f) Emissions from destruction processes and venting of containers. 
You must report the total mass of each fluorinated GHG emitted (in 
metric tons) from:
    (1) 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.
    (2) Venting of residual fluorinated GHGs from containers returned 
from the field.

[75 FR 74831, Dec. 1, 2010, as amended at 79 FR 73785, Dec. 11, 2014



Sec. 98.123  Calculating GHG emissions.

    For fluorinated gas production and transformation processes, you 
must calculate the fluorinated GHG emissions from each process using the 
emission factor or emission calculation factor method specified in 
paragraphs (c), (d), and (e) of this section, as appropriate. For 
destruction processes that destroy fluorinated GHGs that were previously 
``produced'' as defined at Sec. 98.410(b), you must calculate emissions 
using the procedures in paragraph (f) of this section. For venting of 
residual gas from containers (e.g., cylinder heels), you must calculate 
emissions using the procedures in paragraph (g) of this section.
    (a) [Reserved]
    (b) Mass balance method. The mass balance method was available for 
reporting years 2011, 2012, 2013, and 2014 only. See paragraph 1 of 
appendix A of this subpart for the former mass balance method.
    (c) Emission factor and emission calculation factor methods. To use 
the

[[Page 733]]

method in this paragraph for batch processes, you must comply with 
either paragraph (c)(3) of this section (Emission Factor approach) or 
paragraph (c)(4) of this section (Emission Calculation Factor approach). 
To use the method in this paragraph for continuous processes, you must 
first make a preliminary estimate of the emissions from each individual 
continuous process vent under paragraph (c)(1) of this section. If your 
continuous process operates under different conditions as part of normal 
operations, you must also define the different operating scenarios and 
make a preliminary estimate of the emissions from the vent for each 
operating scenario. Then, compare the preliminary estimate for each 
continuous process vent (summed across operating scenarios) to the 
criteria in paragraph (c)(2) of this section to determine whether the 
process vent meets the criteria for using the emission factor method 
described in paragraph (c)(3) of this section or whether the process 
vent meets the criteria for using the emission calculation factor method 
described in paragraph (c)(4) of this section. For continuous process 
vents that meet the criteria for using the emission factor method 
described in paragraph (c)(3) of this section and that have more than 
one operating scenario, compare the preliminary estimate for each 
operating scenario to the criteria in (c)(3)(ii) to determine whether an 
emission factor must be developed for that operating scenario.
    (1) Preliminary estimate of emissions by process vent. You must 
estimate the annual CO2e emissions of fluorinated GHGs for 
each process vent within each operating scenario of a continuous process 
using the approaches specified in paragraph (c)(1)(i) or (c)(1)(ii) of 
this section, accounting for any destruction as specified in paragraph 
(c)(1)(iii) of this section. You must determine emissions of fluorinated 
GHGs by process vent by using measurements, by using calculations based 
on chemical engineering principles and chemical property data, or by 
conducting an engineering assessment. You may use previous measurements, 
calculations, and assessments if they represent current process 
operating conditions or process operating conditions that would result 
in higher fluorinated GHG emissions than the current operating 
conditions and if they were performed in accordance with paragraphs 
(c)(1)(i), (c)(1)(ii), and (c)(1)(iii) of this section, as applicable. 
You must document all data, assumptions, and procedures used in the 
calculations or engineering assessment and keep a record of the 
emissions determination as required by Sec. 98.127(a).
    (i) Engineering calculations. For process vent emission 
calculations, you may use any of paragraphs (c)(1)(i)(A), (c)(1)(i)(B), 
or (c)(1)(i)(C) of this section.
    (A) U.S. Environmental Protection Agency, Emission Inventory 
Improvement Program, Volume II: Chapter 16, Methods for Estimating Air 
Emissions from Chemical Manufacturing Facilities, August 2007, Final 
(incorporated by reference, see Sec. 98.7).
    (B) You may determine the fluorinated GHG emissions from any process 
vent within the process using the procedures specified in Sec. 
63.1257(d)(2)(i) and (d)(3)(i)(B) of this chapter, except as specified 
in paragraphs (c)(1)(i)(B)(1) through (c)(1)(i)(B)(4) of this section. 
For the purposes of this subpart, use of the term ``HAP'' in Sec. 
63.1257(d)(2)(i) and (d)(3)(i)(B) of this chapter means ``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) of this chapter.
    (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) of this chapter.
    (3) To calculate emissions from vacuum systems, the terms used in 
Equation 33 to Sec. 63.1257(d)(2)(i)(E) of this chapter 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

[[Page 734]]

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 emissions when a vessel is equipped with a process 
condenser or a control condenser, you must use the procedures in Sec. 
63.1257(d)(3)(i)(B) of this chapter, 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, if the 
condensate receiver composition is not known.
    (iv) For the emissions from gas evolution, the term for time, t, 
must be used in Equation 12 to Sec. 63.1257(d)(2)(i)(B) of this 
chapter.
    (v) Emissions from empty vessel purging must be calculated using 
Equation 36 to Sec. 63.1257(d)(2)(i)(H) of this chapter 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 (e.g., including the calculation methodologies in paragraphs 
(c)(1)(i)(A) and (c)(1)(i)(B) of this section).
    (ii) Engineering assessments. For process vent emissions 
determinations, you may conduct an engineering assessment to calculate 
uncontrolled emissions. 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 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.
    (iii) Impact of destruction for the preliminary estimate. If the 
process vent is vented to a destruction device, you may reflect the 
impact of the destruction device on emissions. In your emissions 
estimate, account for the following:
    (A) The destruction efficiencies of the device that have been 
demonstrated for the fluorinated GHGs in the vent stream for periods 
when the process vent is vented to the destruction device.
    (B) Any periods when the process vent is not vented to the 
destruction device.
    (iv) Use of typical recent values. In the calculations in paragraphs 
(c)(1)(i), (c)(1)(ii), and (c)(1)(iii) of this section, the values used 
for the expected process activity and for the expected fraction of that 
activity whose emissions will be vented to the properly functioning 
destruction device must be based on either typical recent values for the 
process or values that would overestimate emissions from the process, 
unless there is a compelling reason to adopt a different value (e.g., 
installation of a destruction device for a previously uncontrolled 
process). If there is such a reason, it must be documented in the GHG 
Monitoring Plan.
    (v) GWPs. To convert the fluorinated GHG emissions to 
CO2e, use Equation A-1 of Sec. 98.2.
    (vi) [Reserved]
    (2) Method selection for continuous process vents.
    (i) If the calculations under paragraph (c)(1) of this section, as 
well as any subsequent measurements and calculations under this subpart, 
indicate

[[Page 735]]

that the continuous process vent has fluorinated GHG emissions of less 
than 10,000 metric ton CO2e per year, summed across all 
operating scenarios, then you may comply with either paragraph (c)(3) of 
this section (Emission Factor approach) or paragraph (c)(4) of this 
section (Emission Calculation Factor approach).
    (ii) If the continuous process vent does not meet the criteria in 
paragraph (c)(2)(i) of this section, then you must comply with the 
emission factor method specified in paragraph (c)(3) (Emission Factor 
approach) of this section.
    (A) You must conduct emission testing for process-vent-specific 
emission factor development before the destruction device unless the 
calculations you performed under paragraph (c)(1)(iii) of this section 
indicate that the uncontrolled fluorinated GHG emissions that occur 
during periods when the process vent is not vented to the properly 
functioning destruction device are less than 10,000 metric tons 
CO2e per year. In this case, you may conduct emission testing 
after the destruction device to develop a process-vent-specific emission 
factor. If you do so, you must develop and apply an emission calculation 
factor under paragraph (c)(4) to estimate emissions during any periods 
when the process vent is not vented to the properly functioning 
destruction device.
    (B) Regardless of the level of uncontrolled emissions, the emission 
testing for process-vent-specific emission factor development may be 
conducted on the outlet side of a wet scrubber in place for acid gas 
reduction, if one is in place, as long as there is no appreciable 
reduction in the fluorinated GHG.
    (3) Process-vent-specific emission factor method. For each process 
vent, conduct an emission test and measure 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 (c)(3). Conduct the emission test 
according to the procedures in Sec. 98.124. All emissions test data and 
procedures used in developing emission factors must be documented 
according to Sec. 98.127. If more than one operating scenario applies 
to the process that contains the subject process vent, you must comply 
with either paragraph (3)(i) or paragraph (3)(ii) of this section.
    (i) Conduct a separate emissions test for operation under each 
operating scenario.
    (ii) Conduct an emissions test for the operating scenario that is 
expected to have the largest emissions in terms of CO2e 
(considering both activity levels and emission calculation factors) on 
an annual basis. Also conduct an emissions test for each additional 
operating scenario that is estimated to emit 10,000 metric tons 
CO2e or more annually from the vent and whose emission 
calculation factor differs by 15 percent or more from the emission 
calculation factor of the operating scenario that is expected to have 
the largest emissions (or of another operating scenario for which 
emission testing is performed), unless the difference between the 
operating scenarios is solely due to the application of a destruction 
device to emissions under one of the operating scenarios. For any other 
operating scenarios, adjust the process-vent specific emission factor 
developed for the operating scenario that is expected to have the 
largest emissions (or for another operating scenario for which emission 
testing is performed) using the approach in paragraph (c)(3)(viii) of 
this section.
    (iii) You must measure the process activity, such as the process 
feed rate, process production rate, or other process activity rate, as 
applicable, during the emission test and calculate the rate for the test 
period, in kg (or another appropriate metric) per hour.
    (iv) For continuous processes, you must calculate the hourly

individual process vent, EPV, by using measurements, by using 
calculations based on chemical engineering principles and chemical 
property data, or by conducting an engineering assessment. Use the 
procedures in paragraphs (c)(1)(i) or (ii) of this section, except 
paragraph (c)(1)(ii)(C) of this section. The procedures in paragraphs 
(c)(1)(i) and (ii) of this section may be applied either to batch 
process vents or to continuous process vents. The uncontrolled emissions 
must be based on a typical batch or production rate under a defined 
operating scenario. The process activity rate associated with the 
uncontrolled emissions must be determined. The methods, data, and 
assumptions used to estimate emissions for each operating scenario must 
be selected to yield a best estimate (expected value) of emissions 
rather than an over- or underestimate of emissions for that operating 
scenario. All data, assumptions, and procedures used in the calculations 
or engineering assessment must be documented according to Sec. 98.127.

    (d) Calculate fluorinated GHG emissions for equipment leaks (EL). If 
you comply with paragraph (c) 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. If 
you conduct monitoring of equipment in fluorinated GHG service, 
monitoring must be conducted for those in light liquid and in gas and 
vapor service. If you conduct monitoring of equipment in fluorinated GHG 
service, you may exclude from monitoring each piece of equipment that is 
difficult-to-monitor, that is unsafe-to-monitor, that is insulated, or 
that is in heavy liquid service; you may exclude from monitoring each

[[Page 740]]

pump with dual mechanical seals, agitator with dual mechanical seals, 
pump with no external shaft, agitator with no external shaft; you may 
exclude from monitoring each pressure relief device in gas and vapor 
service with upstream rupture disk, each sampling connection system with 
closed-loop or closed-purge systems, and any pieces of equipment where 
leaks are routed through a closed vent system to a destruction device. 
You must estimate emissions using another approach for those pieces of 
equipment excluded from monitoring. Equipment that is in fluorinated GHG 
service for less than 300 hr/yr; equipment that is in vacuum service; 
pressure relief devices that are in light liquid service; and 
instrumentation systems are exempted from these requirements.
    (1) The emissions from equipment leaks must be calculated using any 
of the procedures in paragraphs (d)(1)(i), (d)(1)(ii), (d)(1)(iii), or 
(d)(1)(iv) of this section.
    (i) Use of Average Emission Factor Approach in EPA Protocol for 
Equipment Leak Emission Estimates. The emissions from equipment leaks 
may be calculated using the default Average Emission Factor Approach in 
EPA-453/R-95-017 (incorporated by reference, see Sec. 98.7).
    (ii) Use of Other Approaches in EPA Protocol for Equipment Leak 
Emission Estimates in conjunction with EPA Method 21 at 40 CFR part 60, 
appendix A-7. The emissions from equipment leaks may be calculated using 
one of the following methods in EPA-453/R-95-017 (incorporated by 
reference, see Sec. 98.7): The Screening Ranges Approach; the EPA 
Correlation Approach; or the Unit-Specific Correlation Approach. If you 
determine that EPA Method 21 at 40 CFR part 60, appendix A-7 is 
appropriate for monitoring a fluorinated GHG, and if you calibrate your 
instrument with a compound different from one or more of the fluorinated 
GHGs or surrogates to be measured, you must develop response factors for 
each fluorinated GHG or for each surrogate to be measured using EPA 
Method 21 at 40 CFR part 60, appendix A-7. For each fluorinated GHG or 
surrogate measured, the response factor must be less than 10. The 
response factor is the ratio of the known concentration of a fluorinated 
GHG or surrogate to the observed meter reading when measured using an 
instrument calibrated with the reference compound.
    (iii) Use of Other Approaches in EPA Protocol for Equipment Leak 
Emission Estimates in conjunction with site-specific leak monitoring 
methods. The emissions from equipment leaks may be calculated using one 
of the following methods in EPA-453/R-95-017 (incorporated by reference, 
see Sec. 98.7): The Screening Ranges Approach; the EPA Correlation 
Approach; or the Unit-Specific Correlation Approach. You may develop a 
site-specific leak monitoring method appropriate for monitoring 
fluorinated GHGs or surrogates to use along with these three approaches. 
The site-specific leak monitoring method must meet the requirements in 
Sec. 98.124(f)(1).
    (iv) Use of site-specific leak monitoring methods. The emissions 
from equipment leaks may be calculated using a site-specific leak 
monitoring method. The site-specific leak monitoring method must meet 
the requirements in Sec. 98.124(f)(1).
    (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 may be required to 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; or associated screening data and leak rate data 
(i.e., bagging) used to develop a unit-specific correlation.
    (3) Calculate and sum the emissions of each fluorinated GHG in 
metric tons per year for equipment pieces for each process, 
EELf, annually. You must include and estimate emissions for 
types of equipment that are excluded from monitoring, including 
difficult-to-monitor, unsafe-to-monitor and insulated pieces of 
equipment, pieces of equipment in heavy liquid service, pumps

with no external shaft, agitators with no external shaft, pressure 
relief devices in gas and vapor service with upstream rupture disk, 
sampling connection systems with closed-loop or closed purge systems, 
and pieces of equipment where leaks are routed through a closed vent 
system to a destruction device.
    (e) Calculate total fluorinated GHG emissions for each process and 
for production or transformation processes at the facility. (1) Estimate 
annually the total mass of each fluorinated GHG emitted from each 
process, including emissions from process vents in paragraphs (c)(3) and 
(c)(4) of this section, as appropriate, and from equipment leaks in 
paragraph (d), using Equation L-29 of this section.

          appropriate).

          leaks for pieces of equipment for process i, annually (kg/

from each type of production or transformation process at the facility 
using Equation L-30 of this section. Develop separate totals for

transform fluorinated gases produced at the facility, and transformation 
processes that transform fluorinated gases produced at another facility.

          gas production processes, all transformation processes that 
          transform fluorinated gases produced at the facility, or all

          produced at another facility, as appropriate (metric tons).

          gas transformation processes that transform fluorinated gases 
          produced at the facility, or transformation processes that 
          transform fluorinated gases produced at another facility, as 
          appropriate.

    (f) Calculate fluorinated GHG emissions from destruction of 
fluorinated GHGs that were previously ``produced''. Estimate annually 
the total mass of fluorinated GHGs emitted from destruction of 
fluorinated GHGs that were previously ``produced'' as defined at Sec. 
98.410(b) using Equation L-31 of this section:

RED = The mass of fluorinated GHGs that were previously 
          ``produced'' as defined at Sec. 98.410(b) and that are fed 
          annually into the destruction device (metric tons).
DE = Destruction efficiency of the destruction device (fraction).

    (g) Emissions from venting of residual fluorinated GHGs in 
containers. If you vent residual fluorinated GHGs from containers, you 
must either measure the residual fluorinated GHGs vented from each 
container or develop a heel factor for each combination of fluorinated 
GHG, container size, and container type that you vent. You do not need 
to estimate de minimis emissions associated with good-faith attempts to 
recycle or recover residual fluorinated GHGs in or from containers.
    (1) Measuring contents of each container. If you weigh or otherwise 
measure the contents of each container before venting the residual 
fluorinated GHGs, use Equation L-32 of this section to calculate annual 
emissions of each fluorinated GHG from venting of residual fluorinated 
GHG from containers. Convert pressures to masses as directed in 
paragraph (g)(2)(ii) of this section.
[GRAPHIC] [TIFF OMITTED] TR11DE14.001

          received by facility (metric tons).

          after evacuation by facility (metric tons). (Facility may 
          equate to zero.)
n = Number of vented containers for each fluorinated GHG f.

    (2) Developing and applying heel factors. If you use heel factors to 
estimate emissions of residual fluorinated GHGs vented from containers, 
you must annually develop these factors based on representative samples 
of the containers received by your facility from fluorinated GHG users.
    (i) Sample size. For each combination of fluorinated GHG, container 
size, and container type that you vent, select a representative sample 
of containers that reflects the full range of quantities of residual gas 
returned in that container size and type. This sample must reflect the 
full range of the industries and a broad range of the customers that use 
and return the fluorinated GHG, container size, and container type. The 
minimum sample size for each combination of fluorinated GHG, container 
size, and container type must be 30, unless this is greater than the 
number of containers returned within that combination annually, in which 
case the contents of every container returned must be measured.
    (ii) Measurement of residual gas. The residual weight or pressure 
you use for paragraph (g)(1) of this section must be determined by 
monitoring the mass or the pressure of your cylinders/containers 
according to Sec. 98.124(k). If you monitor the pressure, convert the 
pressure to mass using a form of the ideal gas law, as displayed in 
Equation L-33 of this section, with an appropriately selected Z value.

and container type, use paragraph (g)(1) of this section to calculate 
the total heel emissions for each sample selected under paragraph 
(g)(2)(i) of this section. Divide this total by the number of containers 
in the sample. Divide the result by the full capacity (the mass of the 
contents of a full container) of that combination of fluorinated GHG, 
container size, and container type. The heel factor is expressed as a 
fraction of the full capacity.

section.

Sec. 98.124  Monitoring and QA/QC requirements.

    (a) Initial scoping speciation to identify fluorinated GHGs. You 
must conduct an initial scoping speciation to identify all fluorinated 
GHGs that may be generated from processes that are subject to this 
subpart and that have at least one process vent with uncontrolled 
emissions of 1.0 metric ton or more of fluorinated GHGs per year based 
on the preliminary estimate of emissions in Sec. 98.123(c)(1). You are 
not required to quantify emissions under this initial scoping 
speciation. Only fluorinated GHG products and by-products that occur in 
greater than trace concentrations in at least one stream must be 
identified under this paragraph.
    (1) Procedure. To conduct the scoping speciation, select 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 at their maximum 
concentrations and sample and analyze the contents of these selected 
streams or process vents. For example, if fluorinated GHG by-products 
are separated into one low-boiling-point and one high-boiling-point 
stream, sample and analyze both of these streams. Alternatively, you may 
sample and analyze streams where fluorinated GHG by-products occur at 
less than their maximum concentrations, but you must ensure that the 
sensitivity of the analysis is sufficient to compensate for the expected 
difference in concentration. For example, if you sample and analyze 
streams where fluorinated GHG by-products are expected to occur at one 
half their maximum concentrations elsewhere in the process, you must 
ensure that the sensitivity of the analysis is sufficient to detect 
fluorinated GHG by-products that occur at concentrations of 0.05 percent 
or higher. You do not have to sample and analyze every stream or process 
vent, i.e., you do not have to sample and analyze a stream or process 
vent that contains only fluorinated GHGs that are contained in other 
streams or process vents that are being sampled and analyzed. Sampling 
and analysis must be conducted according to the procedures in paragraph 
(e) of this section.
    (2) Previous measurements. If you have conducted testing of streams 
(including process streams or destroyed streams) or process vents less 
than 10 years before December 31, 2010, and the testing meets the 
requirements in paragraph (a)(1) of this section, you may use the 
previous testing to satisfy this requirement.
    (b) Mass balance monitoring. Mass balance monitoring was available 
for reporting years 2011, 2012, 2013, and 2014 only. See paragraph 2 of 
Appendix A of this subpart for the former mass balance method.
    (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 that is based on 
representative performance of the process or operating scenario(s) of 
the process, as applicable. For process vents for which you performed an 
initial scoping speciation, include in the emission test any fluorinated 
GHG that was identified in the initial scoping speciation. For process 
vents for which you did not perform an initial scoping speciation, 
include in the emission test any

[[Page 745]]

fluorinated greenhouse gas that occurs in more than trace concentrations 
in the vent stream or, where a destruction device is used, in the inlet 
to the destruction device. You may include startup and shutdown events 
if the testing is sufficiently long or comprehensive to ensure that such 
events are not overrepresented in the emission factor. Malfunction 
events must not be included in the testing. If you do not detect a 
fluorinated GHG that was identified in the scoping speciation or that 
occurs in more than trace concentrations in the vent stream or in the 
inlet to the destruction device, assume that fluorinated GHG was emitted 
at one half of the detection limit.
    (2) Number of runs. For continuous processes, sample the process 
vent for a minimum of three runs of 1 hour each. If the relative 
standard deviation (RSD) of the emission factor calculated based on the 
first three runs is greater than or equal to 0.15 for the emission 
factor, continue to sample the process vent for an additional three runs 
of 1 hour each. If more than one fluorinated GHG is measured, the RSD 
must be expressed in terms of total CO2e.
    (3) 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.
    (4) Sample each process. If process vents from separate processes 
are manifolded together to a common vent or to a common destruction 
device, you must follow paragraph (c)(4)(i), (c)(4)(ii), or (c)(4)(iii) 
of this section.
    (i) You may sample emissions from each process in the ducts before 
the emissions are combined.
    (ii) You may sample in the common duct or at the outlet of the 
destruction device when only one process is operating.
    (iii) You may sample the combined emissions and use engineering 
calculations and assessments as specified in Sec. 98.123(c)(4) to 
allocate the emissions to each manifolded process vent, provided the sum 
of the calculated fluorinated GHG emissions across the individual 
process vents is within 20 percent of the total fluorinated GHG 
emissions measured during the manifolded testing.
    (5) Emission test results. The results of an emission test must 
include the analysis of samples, number of test runs, the results of the 
RSD analysis, the analytical method used, determination of emissions, 
the process activity, and raw data and must identify the process, the 
operating scenario, the process vents tested, and the fluorinated GHGs 
that were included in the test. 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).
    (6) Emissions testing frequency. You must conduct emissions testing 
to develop the process-vent-specific emission factor under paragraph 
(c)(7)(i) or (c)(7)(ii) of this section, whichever occurs first:
    (i) 10-year revision. Conduct an emissions test every 10 years. In 
the calculations under Sec. 98.123, apply the revised process-vent-
specific emission factor to the process activity that occurs after the 
revision.
    (ii) Operating scenario change that affects the emission factor. For 
planned operating scenario changes, you must estimate and compare the 
emission calculation factors for the changed operating scenario and for 
the original operating scenario whose process vent specific emission 
factor was measured. Use the calculation methods in Sec. 98.123(c)(4). 
If the emission calculation

[[Page 746]]

factor for the changed operating scenario is 15 percent or more 
different from the emission calculation factor for the previous 
operating scenario (this includes the cumulative change in the emission 
calculation factor since the last emissions test), you must conduct an 
emissions test to update the process-vent-specific emission factor, 
unless the difference between the operating scenarios is solely due to 
the application of a destruction device to emissions under the changed 
operating scenario. Conduct the test before February 28 of the year that 
immediately follows the change. In the calculations under Sec. 98.123, 
apply the revised process-vent-specific emission factor to the process 
activity that occurs after the operating scenario change.
    (7) Subsequent measurements. If a continuous process vent with 
fluorinated GHG emissions less than 10,000 metric tons CO2e, 
per Sec. 98.123(c)(2), is later found to have fluorinated GHG emissions 
of 10,000 metric tons CO2e or greater, you must conduct the 
emissions testing for the process vent during the following year and 
develop the process-vent-specific emission factor from the emissions 
testing.
    (8) Previous measurements. If you have conducted an emissions test 
less than 10 years before December 31, 2010, and the emissions testing 
meets the requirements in paragraphs (c)(1) through (c)(8) of this 
section, you may use the previous emissions testing to develop process-
vent-specific emission factors. For purposes of paragraph (c)(7)(i) of 
this section, the date of the previous emissions test rather than 
December 31, 2010 shall constitute the beginning of the 10-year re-
measurement cycle.
    (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)(4) of this section.
    (1) Operating scenario. Perform the emissions calculation for the 
process vent based on representative performance of the operating 
scenario of the process. If more than one operating scenario applies to 
the process that contains the subject process vent, you must conduct a 
separate emissions calculation for operation under each operating 
scenario. For each continuous process vent that contains more than trace 
concentrations of any fluorinated GHG and for each batch process vent 
that contains more than trace concentrations of any fluorinated GHG, 
develop the process-vent-specific emission calculation factor for each 
operating scenario. For continuous process vents, determine the 
emissions based on the process activity for the representative 
performance of the operating scenario. For batch process vents, 
determine emissions based on the process activity for each typical batch 
operating scenario.
    (2) 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.
    (3) Emission calculation results. The emission calculation must be 
documented by identifying the process, the operating scenario, and the 
process vents. The documentation must contain the information and data 
used to calculate the process-vent-specific emission calculation factor.
    (4) Operating scenario change that affects the emission calculation 
factor. For planned operating scenario changes that are expected to 
change the process-vent-specific emission calculation factor, you must 
conduct an emissions calculation to update the process-vent-specific 
emission calculation factor. In the calculations under Sec. 98.123, 
apply the revised emission calculation factor to the process activity 
that occurs after the operating scenario change.
    (5) Previous calculations. If you have performed an emissions 
calculation for the process vent and operating scenario less than 10 
years before December 31, 2010, and the emissions calculation meets the 
requirements in paragraphs (d)(1) through (d)(4) of this section and in 
Sec. 98.123(c)(4)(i) and (c)(4)(ii), you may use the previous 
calculation to develop the site-specific process-vent-specific emission 
calculation factor.
    (e) Emission and stream testing, including analytical methods. 
Select and document testing and analytical methods as follows:

[[Page 747]]

    (1) Sampling and mass measurement for emission testing. For emission 
testing in process vents or at the stack, use methods for sampling, 
measuring volumetric flow rates, non-fluorinated-GHG gas analysis, and 
measuring stack gas moisture that have been validated using a 
scientifically sound validation protocol.
    (i) Sample and velocity traverses. Acceptable methods include but 
are not limited to EPA Method 1 or 1A in Appendix A-1 of 40 CFR part 60.
    (ii) Velocity and volumetric flow rates. Acceptable methods include 
but are not limited to EPA Method 2, 2A, 2B, 2C, 2D, 2F, or 2G in 
Appendix A-1 of 40 CFR part 60. Alternatives that may be used for 
determining flow rates include OTM-24 (incorporated by reference, see 
Sec. 98.7) and ALT-012 (incorporated by reference, see Sec. 98.7).
    (iii) Non-fluorinated-GHG gas analysis. Acceptable methods include 
but are not limited to EPA Method 3, 3A, or 3B in Appendix A-1 of 40 CFR 
part 60.
    (iv) Stack gas moisture. Acceptable methods include but are not 
limited to EPA Method 4 in Appendix A-1 of 40 CFR part 60.
    (2) Analytical methods. Use a quality-assured analytical measurement 
technology capable of detecting the analyte of interest at the 
concentration of interest and use a sampling and analytical procedure 
validated with the analyte of interest at the concentration of interest. 
Where calibration standards for the analyte are not available, a 
chemically similar surrogate may be used. Acceptable analytical 
measurement technologies include but are not limited to gas 
chromatography (GC) with an appropriate detector, infrared (IR), fourier 
transform infrared (FTIR), and nuclear magnetic resonance (NMR). 
Acceptable methods for determining fluorinated GHGs include EPA Method 
18 in appendix A-1 of 40 CFR part 60, EPA Method 320 in appendix A of 40 
CFR part 63, EPA 430-R-10-003 (incorporated by reference, see Sec. 
98.7), ASTM D6348-03 (incorporated by reference, see Sec. 98.7), or 
other analytical methods validated using EPA Method 301 at 40 CFR part 
63, appendix A or some other scientifically sound validation protocol. 
Acceptable methods for determining total fluorine concentrations for 
fluorine-containing compounds in streams under paragraph (b)(3) of this 
section include ASTM D7359-08 (incorporated by reference, see Sec. 
98.7), or other analytical methods validated using EPA Method 301 at 40 
CFR part 63, appendix A or some other scientifically sound validation 
protocol. The validation protocol may include analytical technology 
manufacturer specifications or recommendations.
    (3) Documentation in GHG Monitoring Plan. Describe the sampling, 
measurement, and analytical method(s) used under paragraphs (e)(1) and 
(e)(2) of this section in the GHG Monitoring Plan as required under 
Sec. 98.3(g)(5). Identify the methods used to obtain the samples and 
measurements listed under paragraphs (e)(1)(i) through (e)(1)(iv) of 
this section. At a minimum, include in the description of the analytical 
method a description of the analytical measurement equipment and 
procedures, quantitative estimates of the method's accuracy and 
precision for the analytes of interest at the concentrations of 
interest, as well as a description of how these accuracies and 
precisions were estimated, including the validation protocol used.
    (f) Emission monitoring for pieces of equipment. If you conduct a 
site-specific leak detection method or monitoring approach for pieces of 
equipment, follow paragraph (f)(1) or (f)(2) of this section and follow 
paragraph (f)(3) of this section.
    (1) Site-specific leak monitoring approach. You may develop a site-
specific leak monitoring approach. You must validate the leak monitoring 
method and describe the method and the validation in the GHG Monitoring 
Plan. To validate the site-specific method, you may, for example, 
release a known rate of the fluorinated GHGs or surrogates of interest, 
or you may compare the results of the site-specific method to those of a 
method that has been validated for the fluorinated GHGs or surrogates of 
interest. In the description of the leak detection method and its 
validation, include a detailed description of the method, including the 
procedures and equipment used and any sampling strategies. Also include 
the

[[Page 748]]

rationale behind the method, including why the method is expected to 
result in an unbiased estimate of emissions from equipment leaks. If the 
method is based on methods that are used to detect or quantify leaks or 
other emissions in other regulations, standards, or guidelines, identify 
and describe the regulations, standards, or guidelines and why their 
methods are applicable to emissions of fluorinated GHGs or surrogates 
from leaks. Account for possible sources of error in the method, e.g., 
instrument detection limits, measurement biases, and sampling biases. 
Describe validation efforts, including but not limited to any 
comparisons against standard leaks or concentrations, any comparisons 
against other methods, and their results. If you use the Screening 
Ranges Approach, the EPA Correlation Approach, or the Unit-Specific 
Correlation Approach with a monitoring instrument that does not meet all 
of the specifications in EPA Method 21 at 40 CFR part 60, appendix A-7, 
then explain how and why the monitoring instrument, as used at your 
facility, would nevertheless be expected to accurately detect and 
quantify emissions of fluorinated GHGs or surrogates from process 
equipment, and describe how you verified its accuracy. For all methods, 
provide a quantitative estimate of the accuracy and precision of the 
method.
    (2) EPA Method 21 monitoring. If you determine that EPA Method 21 at 
40 CFR part 60, appendix A-7 is appropriate for monitoring a fluorinated 
GHG, conduct the screening value concentration measurements using EPA 
Method 21 at 40 CFR part 60, appendix A-7 to determine the screening 
range data or the actual screening value data for the Screening Ranges 
Approach, EPA Correlation Approach, or the Unit-Specific Correlation 
Approach. For the one-time testing to develop the Unit-Specific 
Correlation equations in EPA-453/R-95-017 (incorporated by reference, 
see Sec. 98.7), conduct the screening value concentration measurements 
using EPA Method 21 at 40 CFR part 60, appendix A-7 and the bagging 
procedures to measure mass emissions. Concentration measurements of 
bagged samples must be conducted using gas chromatography following EPA 
Method 18 analytical procedures or other method according to Sec. 
98.124(e). Use methane or other appropriate compound as the calibration 
gas.
    (3) Frequency of measurement and sampling. If you estimate emissions 
based on monitoring of equipment, conduct monitoring at least annually. 
Sample at least one-third of equipment annually (except for equipment 
that is unsafe-to-monitor, difficult-to-monitor, insulated, or in heavy 
liquid service, pumps with dual mechanical seals, agitators with dual 
mechanical seals, pumps with no external shaft, agitators with no 
external shaft, pressure relief devices in gas and vapor service with an 
upstream rupture disk, sampling connection systems with closed-loop or 
closed purge systems, and pieces of equipment whose leaks are routed 
through a closed vent system to a destruction device), changing the 
sample each year such that at the end of three years, all equipment in 
the process has been monitored. If you estimate emissions based on a 
sample of the equipment in the process, ensure that the sample is 
representative of the equipment in the process. If you have multiple 
processes that have similar types of equipment in similar service, and 
that produce or transform similar fluorinated GHGs (in terms of chemical 
composition, molecular weight, and vapor pressure) at similar pressures 
and concentrations, then you may annually sample all of the equipment in 
one third of these processes rather than one third of the equipment in 
each process.
    (g) Destruction device performance testing. If you vent or otherwise 
feed fluorinated GHGs into a destruction device and apply the 
destruction efficiency of the device to one or more fluorinated GHGs in 
Sec. 98.123, you must conduct emissions testing to determine the 
destruction efficiency for each fluorinated GHG to which you apply the 
destruction efficiency. You must either determine the destruction 
efficiency for the most-difficult-to-destroy fluorinated GHG fed into 
the device (or a surrogate that is still more difficult to destroy) and 
apply that destruction efficiency to all the fluorinated GHGs

[[Page 749]]

fed into the device or alternatively determine different destruction 
efficiencies for different groups of fluorinated GHGs using the most-
difficult-to-destroy fluorinated GHG of each group (or a surrogate that 
is still more difficult to destroy).
    (1) Destruction efficiency testing. 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 (e) of this section. To 
determine the destruction efficiency, emission testing must 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 
or that belongs to the group of fluorinated GHGs for which you wish to 
establish a DE. If the outlet concentration of a fluorinated GHG that is 
fed into the device is below the detection limit of the method, you may 
use a concentration of one-half the detection limit to estimate the 
destruction efficiency.
    (i) If perfluoromethane (CF4) is vented to the 
destruction device in any stream in more than trace concentrations, you 
must test and determine the destruction efficiency achieved specifically 
for CF4 to take credit for the CF4 emissions 
reduction.
    (ii) If sulfur hexafluoride (SF6) is vented to the 
destruction device in any stream in more than trace concentrations, you 
must test and determine the destruction efficiency achieved specifically 
for SF6, or alternatively for CF4 as a surrogate, 
to take credit for the SF6 emissions reduction.
    (iii) If saturated perfluorocarbons other than CF4 are 
vented to the destruction device in any stream in more than trace 
concentrations, you must test and determine the destruction efficiency 
achieved for the lowest molecular weight saturated perfluorocarbon 
vented to the destruction device, or alternatively for a lower molecular 
weight saturated PFC or SF6 as a surrogate, to take credit 
for the PFC emission reduction.
    (iv) For all other fluorinated GHGs that are vented to the 
destruction device in any stream in more than trace concentrations, you 
must test and determine the destruction efficiency achieved for the 
most-difficult-to-destroy fluorinated GHG or surrogate vented to the 
destruction device. Examples of acceptable surrogates include the Class 
1 compounds (ranked 1 through 34) in Appendix D, Table D-1 of ``Guidance 
on Setting Permit Conditions and Reporting Trial Burn Results; Volume II 
of the Hazardous Waste Incineration Guidance Series,'' January 1989, EPA 
Publication EPA 625/6-89/019. You can obtain a copy of this publication 
by contacting the Environmental Protection Agency, 1200 Pennsylvania 
Avenue, NW., Washington, DC 20460, (202) 272-0167, http://www.epa.gov.
    (2) Destruction efficiency testing frequency. You must conduct 
emissions testing to determine the destruction efficiency as provided in 
paragraphs (g)(2)(i) or (ii) of this section, whichever occurs first:
    (i) Conduct an emissions test every 10 years. In the calculations 
under Sec. 98.123, apply the updated destruction efficiency to the 
destruction that occurs after the test.
    (ii) Destruction device changes that affect the destruction 
efficiency. If you make a change to the destruction device that would be 
expected to affect the destruction efficiency, you must conduct an 
emissions test to update the destruction efficiency. Conduct the test 
before the February 28 of the year that immediately follows the change. 
In the calculations under Sec. 98.123, apply the updated destruction 
efficiency to the destruction that occurs after the change to the 
device.
    (3) Previous testing .If you have conducted an emissions test within 
the 10 years prior to December 31, 2010, and the emissions testing meets 
the requirements in paragraph (g)(1) of this section, you may use the 
destruction efficiency determined during this previous emissions 
testing. For purposes of paragraph (g)(2)(i) of this section, the date 
of the previous emissions test rather than December 31, 2010 shall

[[Page 750]]

constitute the beginning of the 10-year re-measurement cycle.
    (4) Hazardous Waste Combustor testing. If a destruction device used 
to destroy fluorinated GHG is subject to subpart EEE of part 63 of this 
chapter or any portion of parts 260-270 of this chapter, you may apply 
the destruction efficiency specifically determined for CF4, 
SF6, PFCs other than CF4, and all other 
fluorinated GHGs under that test if the testing meets the criteria in 
paragraph (g)(1)(i) through (g)(1)(iv) of this section. If the testing 
of the destruction efficiency under subpart EEE of part 63 of this 
chapter was conducted more than 10 years ago, you may use the most 
recent destruction efficiency test provided that the design, operation, 
or maintenance of the destruction device has not changed since the last 
destruction efficiency test in a manner that could affect the ability to 
achieve the destruction efficiency, and the hazardous waste is fed into 
the normal flame zone.
    (h) Mass of previously produced fluorinated GHGs fed into 
destruction device. You must measure the mass of each fluorinated GHG 
that is fed into the destruction device in more than trace 
concentrations and that was previously produced as defined at Sec. 
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 
concentration of the 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.
    (i) Emissions due to malfunctions of destruction device. In their 
estimates of the mass of fluorinated GHG destroyed, fluorinated gas 
production facilities that destroy fluorinated GHGs must account for any 
temporary reductions in the destruction efficiency that result from any 
malfunctions of the destruction device, including periods of operation 
outside of the operating conditions defined in operating permit 
requirements and/or destruction device manufacturer specifications.
    (j) Emissions due to process startup, shutdown, or malfunctions. 
Fluorinated GHG production facilities must account for fluorinated GHG 
emissions that occur as a result of startups, shutdowns, and 
malfunctions, either recording fluorinated GHG emissions during these 
events, or documenting that these events do not result in significant 
fluorinated GHG emissions. Facilities may use the calculation methods in 
Sec. 98.123(c)(1) to estimate emissions during startups, shutdowns, and 
malfunctions.
    (k) Monitoring for venting residual fluorinated GHG in containers. 
Measure the residual fluorinated GHG in containers received by the 
facility either using scales or using pressure and temperature 
measurements. You may use pressure and temperature measurements only in 
cases where no liquid fluorinated GHG is present in the container. 
Scales must have an accuracy and precision of 1 
percent or better of the filled weight (gas plus tare) of the containers 
of fluorinated GHGs that are typically weighed on the scale. For 
example, for scales that are generally used to weigh cylinders that 
contain 115 pounds of gas when full and that have a tare weight of 115 
pounds, this equates to 1 percent of 230 pounds, 
or 2.3 pounds. Pressure gauges and thermometers 
used to measure quantities that are monitored under this paragraph must 
have an accuracy and precision of 1 percent of 
full scale or better.
    (l) Initial scoping speciations, emissions testing, emission factor 
development, emission calculation factor development, emission 
characterization development, and destruction efficiency determinations 
must be completed by February 29, 2012 for processes and operating 
scenarios that operate between December 31, 2010 and December 31, 2011. 
For other processes and operating scenarios, initial scoping

[[Page 751]]

speciations, emissions testing, emission factor development, emission 
calculation factor development, emission characterization development, 
and destruction efficiency determinations must be complete by February 
28 of the year following the year in which the process or operating 
scenario commences or recommences.
    (m) Calibrate all flow meters, weigh scales, and combinations of 
volumetric and density measures using monitoring instruments traceable 
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.

    (o) Special provisions for estimating 2011 and subsequent year 
emissions.
    (1) Best available monitoring methods. To estimate emissions that 
occur from January 1, 2011 through June 30, 2011, owners or operators 
may use best available monitoring methods for any parameter that cannot 
reasonably be measured according to the monitoring and QA/QC 
requirements of this subpart. The owner or operator must use the 
calculation methodologies and equations in Sec. 98.123, but may use the 
best available monitoring method for any parameter for which it is not 
reasonably feasible to acquire, install, or operate a required piece of 
monitoring equipment, to procure measurement services from necessary 
providers, or to gain physical access to make required measurements in a 
facility by January 1, 2011. Starting no later than July 1, 2011, the 
owner or operator must discontinue using best available methods and 
begin following all applicable monitoring and QA/QC requirements of this 
part, except as provided in paragraphs (o)(2) through (o)(4) of this 
section. Best available monitoring methods means any of the following 
methods specified in this paragraph:
    (i) Monitoring methods currently used by the facility that do not 
meet the specifications of this subpart.
    (ii) Supplier data.

[[Page 752]]

    (iii) Engineering calculations or assessments.
    (iv) Other company records.
    (2) Requests for extension of the use of best available monitoring 
methods to estimate 2011 emissions: parameters other than scoping 
speciations, emission factors, and emission characterizations. The owner 
or operator may submit a request to the Administrator to use one or more 
best available monitoring methods for parameters other than scoping 
speciations, emission factors, or emission characterizations to estimate 
emissions that occur between July 1, 2011 and December 31, 2011.
    (i) Timing of request. The extension request must be submitted to 
EPA no later than February 28, 2011.
    (ii) Content of request. Requests must contain the following 
information:
    (A) A list of specific items of monitoring equipment and measurement 
services for which the request is being made and the locations (e.g., 
processes and vents) where each piece of monitoring equipment will be 
installed and where each measurement service will be provided.
    (B) Identification of the specific rule requirements for which the 
monitoring equipment or measurement service is needed.
    (C) A description of the reasons why the needed equipment could not 
be obtained, installed, or operated or why the needed measurement 
service could not be provided before July 1, 2011. The owner or operator 
must consider all of the data collection and emission calculation 
options outlined in the rule for a specific emissions source before 
claiming that a specific safety, technical, logistical, or legal barrier 
exists.
    (D) If the reason for the extension is that the equipment cannot be 
purchased, delivered, or installed before July 1, 2011, include 
supporting documentation such as the date the monitoring equipment was 
ordered, investigation of alternative suppliers, the dates by which 
alternative vendors promised delivery or installation, backorder notices 
or unexpected delays, descriptions of actions taken to expedite delivery 
or installation, and the current expected date of delivery or 
installation.
    (E) If the reason for the extension is that service providers were 
unable to provide necessary measurement services, include supporting 
documentation demonstrating that these services could not be acquired 
before July 1, 2011. This documentation must include written 
correspondence to and from at least two service providers stating that 
they will not be able to provide the necessary services before July 1, 
2011.
    (F) If the reason for the extension is that the process is operating 
continuously without process shutdown, include supporting documentation 
showing that it is not practicable to isolate the process equipment or 
unit and install the measurement device without a full shutdown or a hot 
tap, and that there is no opportunity before July 1, 2011 to install the 
device. Include the date of the three most recent shutdowns for each 
relevant process equipment or unit, the frequency of shutdowns for each 
relevant process equipment or unit, and the date of the next planned 
process equipment or unit shutdown.
    (G) If the reason for the extension is that access to process 
streams, emissions streams, or destroyed streams, as applicable, could 
not be gained before July 1, 2011 for reasons other than the continuous 
operation of the process without shutdown, include illustrative 
documentation such as photographs and engineering diagrams demonstrating 
that access could not be gained.
    (H) A description of the best available monitoring methods that will 
be used and how their results will be applied (i.e., which calculation 
method will be used) to develop the emission estimate. Where the 
proposed best available monitoring method is the use of current 
monitoring data in the mass-balance approach, include the estimated 
relative and absolute errors of the mass-balance approach using the 
current monitoring data.
    (I) A description of the specific actions the owner or operator will 
take to comply with monitoring requirements by January 1, 2012.
    (3) Requests for extension of the use of best available monitoring 
methods to estimate 2011 emissions: scoping speciations,

[[Page 753]]

emission factors, and emission characterizations. The owner or operator 
may submit a request to the Administrator to use one or more best 
available monitoring methods for scoping speciations, emission factors, 
and emission characterizations to estimate emissions that occur between 
July 1, 2011 and December 31, 2011.
    (i) Timing of request. The extension request must be submitted to 
EPA no later than June 30, 2011.
    (ii) Content of request. Requests must contain the information 
outlined in paragraph (o)(2)(ii) of this section, substituting March 1, 
2012 for July 1, 2011 and substituting March 1, 2013 for January 1, 
2012.
    (iii) Reporting of 2011 emissions using scoping speciations, 
emission factors, and emission characterizations developed after 
February 29, 2012. Facilities that are approved to use best available 
monitoring methods in 2011 for scoping speciations, emission factors, or 
emission characterizations for certain processes must submit, by March 
31, 2013, revised 2011 emission estimates that reflect the scoping 
speciations, emission factors, and emission characterizations that are 
measured for those processes after February 29, 2012. If the operating 
scenario for 2011 is different from all of the operating scenarios for 
which emission factors are developed after February 29, 2012, use 
Equation L-23 at Sec. 98.123(c)(3)(viii) to adjust the emission 
factor(s) or emission characterizations measured for the post-February 
29, 2012 operating scenario(s) to account for the differences.
    (4) Requests for extension of the use of best available monitoring 
methods to estimate emissions that occur after 2011. EPA does not 
anticipate approving the use of best available monitoring methods to 
estimate emissions that occur beyond December 31, 2011; however, EPA 
reserves the right to review requests for unique and extreme 
circumstances which include safety, technical infeasibility, or 
inconsistency with other local, State or Federal regulations.
    (i) Timing of request. The extension request must be submitted to 
EPA no later than June 30, 2011.
    (ii) Content of request. Requests must contain the following 
information:
    (A) The information outlined in paragraph (o)(2)(ii) of this 
section. For scoping speciations, emission factors, and emission 
characterizations, substitute March 1, 2013 for July 1, 2011 and 
substitute March 1, 2014 for January 1, 2012. For other parameters, 
substitute January 1, 2012 for July 1, 2011 and substitute January 1, 
2013 for January 1, 2012.
    (B) A detailed outline of the unique circumstances necessitating an 
extension, including specific data collection issues that do not meet 
safety regulations, technical infeasibility or specific laws or 
regulations that conflict with data collection. The owner or operator 
must consider all the data collection and emission calculation options 
outlined in the rule for a specific emissions source before claiming 
that a specific safety, technical or legal barrier exists.
    (C) A detailed explanation and supporting documentation of how and 
when the owner or operator will receive the required data and/or 
services to comply with the reporting requirements of this subpart in 
the future.
    (E) The Administrator reserves the right to require that the owner 
or operator provide additional documentation.
    (iii) Reporting of 2011 and subsequent year emissions using scoping 
speciations, emission factors, and emission characterizations developed 
after approval to use best available monitoring methods expires. 
Facilities that are approved to use best available monitoring methods in 
2011 and subsequent years for scoping speciations, emission factors, or 
emission characterizations for certain processes must submit, by March 
31 of the year that begins one year after their approval to use best 
available monitoring method(s) expires, revised emission estimates for 
2011 and subsequent years that reflect the scoping speciations, emission 
factors, and emission characterizations that are measured for those 
processes in 2013 or subsequent years. If the operating scenario for 
2011 or subsequent years is different from all of the operating 
scenarios for which emission factors or emission characterizations are 
developed in 2013 or subsequent years, use Equation L-23 of Sec. 
98.123(c)(3)(viii) to adjust the emission

[[Page 754]]

factor(s) or emission characterization(s) measured for the new operating 
scenario(s) to account for the differences.
    (5) Approval criteria. To obtain approval, the owner or operator 
must demonstrate to the Administrator's satisfaction that it is not 
reasonably feasible to acquire, install, or operate the required piece 
of monitoring equipment, to procure measurement services from necessary 
providers, or to gain physical access to make required measurements in a 
facility according to the requirements of this subpart by the dates 
specified in paragraphs (o)(2), (3), and (4) of this section for any of 
the reasons described in paragraph (o)(2)(ii) of this section, or, for 
requests under paragraph (o)(4) of this section, any of the reasons 
described in paragraph (o)(4)(ii)(B) of this section.

[75 FR 74831, Dec. 1, 2010, as amended at 79 FR 73787, Dec. 11, 2014]



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 must be used in the 
calculations as specified in the 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 or 
fluorine-containing compound concentration, the substitute data value 
must 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, or fed into 
destruction devices, the substitute value of that parameter must 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 must 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. 98.126  Data reporting requirements.

    (a) All facilities. In addition to the information required by Sec. 
98.3(c), you must report the information in paragraphs (a)(2) through 
(6) of this section according to the schedule in paragraph (a)(1) of 
this section, except as otherwise provided in paragraph (j) of this 
section or in Sec. 98.3(c)(4)(vii) and Table A-7 of subpart A of this 
part.
    (1) Frequency of reporting under paragraph (a) of this section. The 
information in paragraphs (a)(2) through (6) of this section must be 
reported annually.
    (2) Generically-identified process. For each production and 
transformation process at the facility, you must:
    (i) Provide a number, letter, or other identifier for the process. 
This identifier must be consistent from year to year.
    (ii) Indicate whether the process is a fluorinated gas production 
process, a fluorinated gas transformation process where no fluorinated 
GHG reactant is produced at another facility, or a fluorinated gas 
transformation process where one or more fluorinated GHG reactants are 
produced at another facility.
    (iii) Indicate whether the process could be characterized as 
reaction, distillation, or packaging (include all that apply).
    (iv) For each generically-identified process and each fluorinated 
GHG group, report the method(s) used to determine the mass emissions of 
that fluorinated GHG group from that process from vents (i.e., mass 
balance (for reporting years 2011, 2012, 2013, and 2014

[[Page 755]]

only), process-vent-specific emission factor, or process-vent-specific 
emission calculation factor).
    (v) For each generically-identified process and each fluorinated GHG 
group, report the method(s) used to determine the mass emissions of that 
fluorinated GHG group from that process from equipment leaks, unless you 
used the mass balance method (for reporting years 2011, 2012, 2013, and 
2014 only) for that process.
    (3) Emissions from production and transformation processes, process 
level, multiple products. If your facility produces more than one 
fluorinated gas product, for each generically-identified process and 
each fluorinated GHG group, you must report the total GWP-weighted 
emissions of all fluorinated GHGs in that group from the process, in 
metric tons CO2e.
    (4) Emissions from production and transformation processes, facility 
level, multiple products. If your facility produces more than one 
fluorinated gas product, you must report the information in paragraphs 
(a)(4)(i) and (ii) of this section, as applicable, for emissions from 
production and transformation processes.
    (i) For each fluorinated GHG with emissions of 1,000 metric tons of 
CO2e or more from production and transformation processes, 
summed across the facility as a whole, you must report the total mass in 
metric tons of the fluorinated GHG emitted from production and 
transformation processes, summed across the facility as a whole. If the 
fluorinated GHG does not have a chemical-specific GWP in Table A-1 of 
subpart A, identify the fluorinated GHG group of which that fluorinated 
GHG is a member.
    (ii) For all other fluorinated GHGs emitted from production and 
transformation processes, you must report the total GWP-weighted 
emissions from production and transformation processes of those 
fluorinated GHGs by fluorinated GHG group, summed across the facility as 
a whole, in metric tons of CO2e.
    (5) Emissions from production and transformation processes, facility 
level, one product only. If your facility produces only one fluorinated 
gas product, aggregate and report the total GWP-weighted emissions from 
production and transformation processes of fluorinated GHGs by 
fluorinated GHG group for the facility as a whole, in metric tons of 
CO2e, with the following exception: Where emissions consist 
of a major fluorinated GHG constituent of a fluorinated gas product, and 
the product is sold or transferred to another person, report the total 
mass in metric tons of each fluorinated GHG that is emitted from 
production and transformation processes and that is a major fluorinated 
GHG constituent of the product. If the fluorinated GHG does not have a 
chemical-specific GWP in Table A-1 of subpart A, identify the 
fluorinated GHG group of which that fluorinated GHG is a member.
    (6) Effective destruction efficiency. For each generically-
identified process, use Table L-1 of this subpart to report the range 
that encompasses the effective destruction efficiency, 
DEeffective, calculated for that process using Equation L-35 
of this subpart. The effective destruction efficiency must be reported 
on a CO2e basis.
    (b) Reporting for mass balance method for reporting years 2011, 
2012, 2013, and 2014. If you used the mass balance method to calculate 
emissions for any of the reporting years 2011, 2012, 2013, or 2014, you 
must conduct mass balance reporting for that reporting year. For 
processes whose emissions were determined using the mass balance method 
under the former Sec. 98.123(b), as included in paragraph 1 of Appendix 
A of this subpart, you must report the information listed in paragraphs 
(b)(1) and (b)(2) of this section for each process on an annual basis.
    (1) If you calculated the relative and absolute errors under the 
former Sec. 98.123(b)(1), the overall absolute and relative errors 
calculated for the process under the former Sec. 98.123(b)(1), in 
metric tons CO2e and decimal fraction, respectively.
    (2) The method used to estimate the total mass of fluorine in 
destroyed or recaptured streams (specify the former Sec. 98.123(b)(4) 
or (15), as included in paragraph 1 of Appendix A of this subpart).
    (c) Reporting for emission factor and emission calculation factor 
approach. For

[[Page 756]]

processes whose emissions are determined using the emission factor 
approach under Sec. 98.123(c)(3) or the emission calculation factor 
under Sec. 98.123(c)(4), you must report the following for each 
generically-identified process.
    (1) [Reserved]
    (2) [Reserved]
    (3) For each fluorinated GHG group, the total GWP-weighted mass of 
all fluorinated GHGs in that group emitted from all process vents 
combined, in metric tons of CO2e.
    (4) For each fluorinated GHG group, the total GWP-weighted mass of 
all fluorinated GHGs in that group emitted from equipment leaks, in 
metric tons of CO2e.
    (d) Reporting for missing data. Where missing data have been 
estimated pursuant to Sec. 98.125, you must report:
    (1) The generically-identified process for which the data were 
missing.
    (2) The reason the data were missing, the length of time the data 
were missing, and the method used to estimate the missing data.
    (3) Estimates of the missing data for all missing data associated 
with data elements required to be reported in this section.
    (e) Reporting of destruction device excess emissions data. Each 
fluorinated gas production facility that destroys fluorinated GHGs must 
report the excess emissions that result from malfunctions of the 
destruction device, and these excess emissions must be reflected in the 
fluorinated GHG estimates in the former Sec. 98.123(b) as included in 
paragraph 1 of Appendix A of this subpart for the former mass balance 
method, and in Sec. 98.123(c). Such excess emissions would occur if the 
destruction efficiency was reduced due to the malfunction.
    (f) Reporting of destruction device testing. By March 31, 2012 or by 
March 31 of the year immediately following the year in which it begins 
fluorinated GHG destruction, each fluorinated gas production facility 
that destroys fluorinated GHGs must submit a report containing the 
information in paragraphs (f)(1) through (f)(4) of this section. This 
report is one-time unless you make a change to the destruction device 
that would be expected to affect its destruction efficiencies.
    (1) [Reserved]
    (2) Chemical identity of the fluorinated GHG(s) used in the 
performance test conducted to determine destruction efficiency, 
including surrogates, and information on why the surrogate is sufficient 
to demonstrate the destruction efficiency for each fluorinated GHG, 
consistent with requirements in Sec. 98.124(g)(1), vented to the 
destruction device.
    (3) Date of the most recent destruction device test.
    (4) Name of all applicable Federal or State regulations that may 
apply to the destruction process.
    (5) [Reserved]
    (g) Reporting for destruction of previously produced fluorinated 
GHGs. Each fluorinated gas production facility that destroys fluorinated 
GHGs must report, separately from the fluorinated GHG emissions reported 
under paragraphs (b) or (c) of this section, the following for each 
previously produced fluorinated GHG destroyed:
    (1) [Reserved]
    (2) The mass of the fluorinated GHG emitted from the destruction 
device (metric tons).
    (h) Reporting of emissions from venting of residual fluorinated GHGs 
from containers. Each fluorinated gas production facility that vents 
residual fluorinated GHGs from containers must report the following for 
each fluorinated GHG vented:
    (1) The mass of the residual fluorinated GHG vented from containers 
annually (metric tons).
    (2) [Reserved]
    (i) Reporting of fluorinated GHG products of incomplete combustion 
(PICs) of fluorinated gases. Each fluorinated gas production facility 
that destroys fluorinated gases must submit a one-time report by June 
30, 2011, that describes any measurements, research, or analysis that it 
has performed or obtained that relate to the formation of products of 
incomplete combustion that are fluorinated GHGs during the destruction 
of fluorinated gases. The report must include the methods and results of 
any measurement or modeling studies, including the products of 
incomplete combustion for which the

[[Page 757]]

exhaust stream was analyzed, as well as copies of relevant scientific 
papers, if available, or citations of the papers, if they are not. No 
new testing is required to fulfill this requirement.
    (j) Special provisions for reporting years 2011, 2012, and 2013 
only. For reporting years 2011, 2012, and 2013, the owner or operator of 
a facility must comply with paragraphs (j)(1), (j)(2), and (j)(3) of 
this section.
    (1) Timing. The owner or operator of a facility is not required to 
report the data elements at Sec. 98.3(c)(4)(iii) and paragraphs (a)(2), 
(a)(3), (a)(4), (a)(6), (b), (c), (d), (e), (f), (g), and (h) of this 
section until the later of March 31, 2015 or the date set forth for that 
data element at Sec. 98.3(c)(4)(vii) and Table A-7 of Subpart A of this 
part.
    (2) Excess emissions. Excess emissions of fluorinated GHGs resulting 
from destruction device malfunctions must be reflected in the reported 
facility-wide CO2e emissions but are not required to be 
reported separately.
    (3) Calculation and reporting of CO2e. You must report 
the total fluorinated GHG emissions covered by this subpart, expressed 
in metric tons of CO2e. This includes emissions from all 
fluorinated gas production processes, all fluorinated gas transformation 
processes that are not part of a fluorinated gas production process, all 
fluorinated gas destruction processes that are not part of a fluorinated 
gas production process or a fluorinated gas transformation process, and 
venting of residual fluorinated GHGs from containers returned from the 
field. To convert fluorinated GHG emissions to CO2e for 
reporting under this section, use Equation A-1 of Sec. 98.2. For 
fluorinated GHGs whose GWPs are not listed in Table A-1 of Subpart A of 
this part, use either the default GWP specified below or your best 
estimate of the GWP based on the information described in Sec. 
98.123(c)(1)(vi)(A)(3). Use of quantitative structure activity 
relationships (QSARs) is an acceptable method for determining GWPs in 
situations where pure standards of the ``target'' fluorinated GHG are 
not available, the ``target'' fluorinated GHG cannot be isolated from 
gas streams, and FTIR spectra for the impurities are not available.
    (i) If you choose to use a default GWP rather than your best 
estimate of the GWP for fluorinated GHGs whose GWPs are not listed in 
Table A-1 of Subpart A of this part, use a default GWP of 10,000 for 
fluorinated GHGs that are fully fluorinated GHGs and use a default GWP 
of 2000 for other fluorinated GHGs.
    (ii) Provide the total annual emissions across fluorinated GHGs for 
the entire facility, in metric tons of CO2e, that were 
calculated using the default GWP of 2000.
    (iii) Provide the total annual emissions across fluorinated GHGs for 
the entire facility, in metric tons of CO2e, that were 
calculated using the default GWP of 10,000.
    (iv) Provide the total annual emissions across fluorinated GHGs for 
the entire facility, in metric tons of CO2e, that were 
calculated using your best estimate of the GWP.
    (k) Submission of complete reporting year 2011, 2012, and 2013 GHG 
reports. By March 31, 2015, you must submit annual GHG reports for 
reporting years 2011, 2012, and 2013 that contain the information 
specified in paragraphs (a) through (i) of this section. The reports 
must calculate CO2e using the GWPs in Table A-1 of subpart A 
of this part (as in effect on January 1, 2015). Prior submission of 
partial reports for these reporting years under paragraph (j) of this 
section does not affect your obligation to submit complete reports under 
this paragraph.

Sec. 98.127  Records that must be retained.

    In addition to the records required by Sec. 98.3(g), you must 
retain the dated records specified in paragraphs (a) through (l) of this 
section, as applicable.
    (a) Process information records. (1) Identify all products and 
processes subject to this subpart. Include the unit identification as 
appropriate, the generic process identification reported for the process 
under Sec. 98.126(a)(2)(i) through (iii), and the product with which 
the process is associated.

[[Page 758]]

    (2) Monthly and annual records, as applicable, of all analyses and 
calculations conducted as required under Sec. 98.123, including the 
data monitored under Sec. 98.124, and all information reported as 
required under Sec. 98.126.
    (3) Identify all fluorinated GHGs with emissions of 1,000 metric 
tons CO2e or more from production and transformation 
processes, summed across the facility as a whole, and identify all 
fluorinated GHGs with total emissions less than 1,000 metric tons 
CO2e from production and transformation processes, summed 
across the facility as a whole.
    (4) Calculations used to determine the total GWP-weighted emissions 
of fluorinated GHGs by fluorinated GHG group for each process, in metric 
tons CO2e.
    (b) Scoping speciation. Retain records documenting the information 
collected under Sec. 98.124(a).
    (c) Mass balance method. Retain the following records for each 
process for which the mass balance method was used to estimate emissions 
in reporting years 2011, 2012, 2013, or 2014. If you used an element 
other than fluorine in the mass balance equation pursuant to the former 
Sec. 98.123(b)(3) as included in paragraph 1 of Appendix A of this 
subpart for the former mass balance method, substitute that element for 
fluorine in the recordkeeping requirements of this paragraph.
    (1) The data and calculations used to estimate the absolute and 
relative errors associated with use of the mass-balance approach.
    (2) The data and calculations used to estimate the mass of fluorine 
emitted from the process.
    (3) The data and calculations used to determine the fractions of the 
mass emitted consisting of each reactant (FERd), product 
(FEP), and by-product (FEBk), including the preliminary 
calculations in the former Sec. 98.123(b)(8)(i).
    (d) Emission factor and emission calculation factor method. Retain 
the following records for each process for which the emission factor or 
emission calculation factor method was used to estimate emissions.
    (1) Identify all continuous process vents with emissions of 
fluorinated GHGs that are less than 10,000 metric tons CO2e 
per year and all continuous process vents with emissions of 10,000 
metric tons CO2e per year or more. Include the data and 
calculation used to develop the preliminary estimate of emissions for 
each process vent.
    (2) Identify all batch process vents.
    (3) For each vent, identify the method used to develop the factor 
(i.e., emission factor by emissions test or emission calculation 
factor).
    (4) The emissions test data and reports (see Sec. 98.124(c)(5)) and 
the calculations used to determine the process-vent-specific emission 
factor, including the actual process-vent-specific emission factor, the 
average hourly emission rate of each fluorinated GHG from the process 
vent during the test and the process feed rate, process production rate, 
or other process activity rate during the test.
    (5) The process-vent-specific emission calculation factor and the 
calculations used to determine the process-vent-specific emission 
calculation factor.
    (6) The annual process production quantity or other process activity 
information in the appropriate units, along with the dates and time 
period during which the process was operating and dates and time periods 
the process vents are vented to the destruction device. As an

the destruction device, a facility may track dates and time periods that 
process vents by-pass the destruction device.
    (7) Calculations used to determine annual emissions of each 
fluorinated GHG for each process and the total fluorinated GHG emissions 
for all processes, i.e., total for facility.

facility that destroys fluorinated GHGs and reflects this destruction in 
Sec. 98.123 must retain the emissions performance testing reports 
(including revised reports) for each destruction device. The emissions 
performance testing report must contain all information and data used to 
derive the destruction efficiency for each fluorinated GHG whose 
destruction the facility reflects in Sec. 98.123, as well as the key 
process and device conditions during the test. This information includes 
the following:

this subpart, you must maintain 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;

facility-wide CO2e emissions under Sec. 98.127(j). Where you 
used your best estimate of the GWP, maintain records of the data and 
analysis used to develop that GWP, including the data elements at Sec. 
98.123(c)(1)(vi)(A)(1)through (3). If you have used QSARs to estimate 
the GWP, include information documenting the level of accuracy of the

rate of the ``target'' fluorinated GHG, the quality and quantity of the 
measurements of the radiative forcings and/or reaction rates of the 
fluorinated GHGs used to model these parameters for the ``target'' 
fluorinated GHG, any estimated uncertainties of the modeled forcings 
and/or reaction rates, and descriptions and results of any efforts to 
validate the QSAR model(s).

Sec. 98.128  Definitions.

    Except as provided in this section, 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

    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.

    (1) Each dual mechanical seal system is operated with the barrier 
fluid at a pressure that is at all times (except periods of startup, 
shutdown, or malfunction) greater than the pump or agitator stuffing box 
pressure; or
    (2) Equipped with a barrier fluid degassing reservoir that is routed 
to a process or fuel gas system or connected by a closed-vent system to 
a control device; or
    (3) Equipped with a closed-loop system that purges the barrier fluid 
into a process stream.
    Equipment (for the purposes of Sec. 98.123(d) and Sec. 98.124(f)

where no fluorinated GHG reactant is produced at another facility, or a 
transformation process where one or more fluorinated GHG reactants are 
produced at another facility;
    (2) Further identified as a reaction, distillation, or packaging 
process, or a combination thereof; and
    (3) Tagged with a discrete identifier, such as a letter or number, 
that remains constant from year to year.
    In fluorinated GHG service means that a piece of equipment either 
contains or contacts a feedstock, by-product, or product that is a 
liquid or gas and contains at least 5 percent by weight fluorinated GHG.

    In vacuum service means that equipment is operating at an internal 
pressure which is at least 5 kilopascals below ambient pressure.
    Isolated intermediate means a product of a process that is stored 
before subsequent processing. An isolated intermediate is usually a

    Major fluorinated GHG constituent means a fluorinated GHG 
constituent of a fluorinated gas product that occurs in concentrations 
greater than 1 percent by mass.
    No external shaft pump and No external shaft agitator means any pump 
or agitator that is designed with no externally actuated shaft 
penetrating the pump or agitator housing.
    Operating scenario means any specific operation of a process and 
includes the information specified in paragraphs (1) through (5) of this 
definition for each process. A change or series of changes to any of 
these elements, except for paragraph (4) of this definition, constitutes 
a different operating scenario.

control or destruction device.
    Process means all equipment that collectively functions 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 this subpart 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 (or the point of entry into a control device, 
if any). 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, wastewater emission 
sources, 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 or 
control 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.
    Unsafe-to-monitor means that monitoring personnel would be exposed 
to an immediate danger as a consequence of monitoring the piece of 
equipment. Examples of unsafe-to-monitor equipment include, but are not 
limited to, equipment under extreme pressure or heat.

    Sec. Appendix A to Subpart L of Part 98--Mass Balance Method for 
                       Fluorinated Gas Production

    1. Mass Balance Method for Sec. 98.123(b). [Note: Numbering 
convention here matches original rule text, 75 FR 74774, December 1, 
2010.]
    (b) Mass balance method. Before using the mass balance approach to 
estimate your fluorinated GHG emissions from a process, you must ensure 
that the process and the equipment and methods used to measure it meet 
either the error limits described in this paragraph and calculated under 
paragraph (b)(1) of this section or the requirements specified in 
paragraph Sec. 98.124(b)(8). If you choose to calculate the error 
limits, 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-5 through L-
10 of this section. You may use the mass-balance approach to estimate 
emissions from the process if this calculation results in an absolute 
error of less than or equal to 3,000 metric tons CO2e per 
year or a relative error of less than or equal to 30 percent of the 
estimated CO2e fluorinated GHG emissions. If you do not meet 
either of the error limits or the requirements of paragraph Sec. 
98.124(b)(8), you must use the emission factor approach detailed in 
paragraphs (c), (d), and (e) of this section to estimate emissions from 
the process.
    (1) Error calculation. To perform the calculation, you must first 
calculate the absolute and relative errors associated with the 
quantities calculated using either Equations L-7 through L-10 of this 
section or Equation L-17 of this section. Alternatively, you may 
estimate these errors based on the variability of previous process 
measurements (e.g., the variability of measurements of stream 
concentrations), provided these measurements are representative of the 
current process and current measurement devices and techniques. Once 
errors have been calculated for the quantities in these equations, those 
errors must be used to calculate the errors in Equations L-6 and L-5 of 
this section. You may ignore the errors associated with Equations L-11, 
L-12, and L-13 of this section.
    (i) Where the measured quantity is a mass, the error in the mass 
must 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.
    (ii) Where the measured quantity is a concentration of a stream 
component, the error of the concentration must be equated to the 
accuracy or precision (whichever is larger) with which you estimate the 
mean concentration of that stream component, accounting for the 
variability of the process, the frequency of the measurements, and the 
accuracy or precision (whichever is larger) of the analytical technique 
used to measure the concentration at the concentration measured. If the 
variability of process measurements is used to estimate the error, this 
variability shall be assumed to account both for the variability of the 
process and the precision of the analytical technique. Use standard 
statistical techniques such as the student's t distribution to estimate 
the error of the mean of the concentration measurements as a function of 
process variability and frequency of measurement.
    (iii) 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] TR11DE14.005

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.

    (iv) Equation L-2 of this section provides the general formula for 
calculating the relative errors of sums and differences:

[[Page 765]]


Where:

eSR = Relative error of the sum, expressed as one 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.

    (v) Equation L-3 of this section 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] TR11DE14.007

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.

    (vi) Equation L-4 of this section provides the general formula for 
calculating the relative errors of products:

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.

    (vii) Calculate the absolute error of the emissions estimate in 
terms of CO2e by performing a preliminary estimate of the 
annual CO2e emissions of the process using the method in 
paragraph (b)(1)(viii) of this section. Multiply this result by the 
relative error calculated for the mass of fluorine emitted from the 
process in Equation L-6 of this section.
    (viii) To estimate the annual CO2e emissions of the 
process for use in the error estimate, apply the methods set forth in 
paragraphs (b)(2) through (7) and (b)(9) through (16) of this section to 
representative process measurements. If these process measurements 
represent less than one year of typical process activity, adjust the 
estimated emissions to account for one year of typical process activity. 
To estimate the terms FERd, FEP, and FEBk for use 
in the error estimate for Equations L-11, L-12, and L-13 of this 
section, you must either use emission testing, monitoring of emitted 
streams, and/or engineering calculations or assessments, or in the 
alternative assume that all fluorine is emitted in the form of the 
fluorinated GHG that has the highest GWP among the fluorinated GHGs that 
occur in more than trace concentrations in the process. To convert the 
fluorinated GHG emissions to CO2e, use Equation A-1 of Sec. 
98.2. For fluorinated GHGs whose GWPs are not listed in Table A-1 to 
subpart A of this part, use a default GWP of 2,000.
    (2) The total mass of each fluorinated GHG emitted annually from 
each fluorinated gas production and each fluorinated GHG transformation 
process must be estimated by using Equation L-5 of this section.

    (3) The total mass of fluorine emitted from process i over the

difference between the total mass of fluorine in the reactant(s) (or 
inputs, for processes that do not involve a chemical reaction) and the 
total mass of fluorine in the product (or outputs, for processes that do 
not involve a chemical reaction), accounting for the total mass of 
fluorine in any destroyed or recaptured streams that contain reactants, 
products, or by-products (or inputs or outputs). This calculation must 
be performed using Equation L-6 of this section. An element other than 
fluorine may be used in the mass-balance equation, provided the element 
occurs in all of the fluorinated GHGs fed into or generated by the 
process. In this case, the mass fractions of the element in the 
reactants, products, and by-products must be calculated as appropriate 
for that element.

the total mass of fluorine emitted, EF, estimated in

[[Page 768]]

Equation L-6 of this section, occurs in the form of the fluorinated GHG 
that has the highest GWP among the fluorinated GHGs that occur in more 
than trace concentrations in the process unless you possess emission 
characterization measurements showing otherwise. These emission 
characterization measurements must meet the requirements in paragraph

terms must equal 1. You must document the data and calculations that are 
used to speciate individual compounds and to estimate FERd, 
FEP, and FEBk. Exclude from your calculations the fluorine 
included in FD. For example, exclude fluorine-containing 
compounds that are not fluorinated GHGs and that result from the 
destruction of fluorinated GHGs by any destruction devices (e.g., the 
mass of HF created by combustion of an HFC). However, include emissions 
of fluorinated GHGs that survive the destruction process.

characterize the emissions of any process vent that emits 25,000 metric 
tons CO2e or more as specified in Sec. 98.124(b)(4).

than 25,000 metric tons CO2e, you must characterize emissions 
as specified in Sec. 98.124(b)(5).

    2. Mass Balance Method for Sec. 98.124(b). [Note: Numbering 
convention here matches original rule text, 75 FR 74774, December 1, 
2010.]
    (b) Mass balance monitoring. If you determine fluorinated GHG 
emissions from any process using the mass balance method under Sec. 
98.123(b), you must estimate the total mass of each fluorinated GHG 
emitted from that process at least monthly. Only streams that contain 
greater than trace concentrations of fluorine-containing reactants, 
products, or by-products must be monitored under this paragraph. If you 
use an element other than fluorine in the mass-balance equation pursuant 
to Sec. 98.123(b)(3), substitute that element for fluorine in the 
monitoring requirements of this paragraph.
    (1) Mass measurements. Measure the following masses on a monthly or 
more frequent basis using flowmeters, weigh scales, or a combination of 
volumetric and density measurements with accuracies and precisions that 
allow the facility to meet the error criteria in Sec. 98.123(b)(1):
    (i) Total mass of each fluorine-containing product produced. Account 
for any used fluorine-containing product added into the production 
process upstream of the output measurement as directed at Sec. Sec. 
98.413(b) and 98.414(b). For each product, the mass produced used for 
the mass-balance calculation must be the same as the mass produced that 
is reported under subpart OO of this part, where applicable.
    (ii) Total mass of each fluorine-containing reactant fed into the 
process.
    (iii) The mass removed from the process in each stream fed into the 
destruction device.
    (iv) The mass removed from the process in each recaptured stream.
    (2) Concentration measurements for use with Sec. 98.123(b)(4). If 
you use Sec. 98.123(b)(4) to estimate the mass of fluorine in destroyed 
or recaptured streams, measure the following concentrations at least 
once each calendar month during which the process is operating, on a 
schedule to ensure that the measurements are representative of the full 
range of process conditions (e.g., catalyst age). Measure more 
frequently if this is necessary to meet the error criteria in Sec. 
98.123(b)(1). Use equipment and methods (e.g., gas chromatography) that 
comply with paragraph (e) of this section and that have an accuracy and 
precision that allow the facility to meet the error criteria in Sec. 
98.123(b)(1). Only fluorine-containing reactants, products, and by-
products that occur in a stream in greater than trace concentrations 
must be monitored under this paragraph.
    (i) The concentration (mass fraction) of the fluorine-containing 
product in each stream that is fed into the destruction device.
    (ii) The concentration (mass fraction) of each fluorine-containing 
by-product in each stream that is fed into the destruction device.
    (iii) The concentration (mass fraction) of each fluorine-containing 
reactant in each stream that is fed into the destruction device.
    (iv) The concentration (mass fraction) of each fluorine-containing 
by-product in each stream that is recaptured (cBkl).

[[Page 772]]

    (3) Concentration measurements for use with Sec. 98.123(b)(15). If 
you use Sec. 98.123(b)(15) to estimate the mass of fluorine in 
destroyed or recaptured streams, measure the concentrations listed in 
paragraphs (b)(3)(i) and (ii) of this section at least once each 
calendar month during which the process is operating, on a schedule to 
ensure that the measurements are representative of the full range of 
process conditions (e.g., catalyst age). Measure more frequently if this 
is necessary to meet the error criteria in Sec. 98.123(b)(1). Use 
equipment and methods (e.g., gas chromatography) that comply with 
paragraph (e) of this section and that have an accuracy and precision 
that allow the facility to meet the error criteria in Sec. 
98.123(b)(1). Only fluorine-containing reactants, products, and by-
products that occur in a stream in greater than trace concentrations 
must be monitored under this paragraph.
    (i) The concentration (mass fraction) of total fluorine in each 
stream that is fed into the destruction device.
    (ii) The concentration (mass fraction) of total fluorine in each 
stream that is recaptured.
    (4) Emissions characterization: process vents emitting 25,000 metric 
tons CO2e or more. To characterize emissions from any process vent 
emitting 25,000 metric tons CO2e or more, comply with 
paragraphs (b)(4)(i) through (b)(4)(v) of this section, as appropriate. 
Only fluorine-containing reactants, products, and by-products that occur 
in a stream in greater than trace concentrations must be monitored under 
this paragraph.
    (i) Uncontrolled emissions. If emissions from the process vent are 
not routed through a destruction device, sample and analyze emissions at 
the process vent or stack or sample and analyze emitted streams before 
the process vent. If the process has more than one operating scenario, 
you must either perform the emission characterization for each operating 
scenario or perform the emission characterization for the operating 
scenario that is expected to have the largest emissions and adjust the 
emission characterization for other scenarios using engineering 
calculations and assessments as specified in Sec. 98.123(c)(4). To 
perform the characterization, take three samples under conditions that 
are representative for the operating scenario. Measure the concentration 
of each fluorine-containing compound in each sample. Use equipment and 
methods that comply with paragraph (e) of this section. Calculate the 
average concentration of each fluorine-containing compound across all 
three samples.
    (ii) Controlled emissions using Sec. 98.123(b)(15). If you use 
Sec. 98.123(b)(15) to estimate the total mass of fluorine in destroyed 
or recaptured streams, and if the emissions from the process vent are 
routed through a destruction device, characterize emissions as specified 
in paragraph (b)(4)(i) of this section before the destruction device. 
Apply the destruction efficiency demonstrated for each fluorinated GHG 
in the destroyed stream to that fluorinated GHG. Exclude from the 
characterization fluorine-containing compounds that are not fluorinated 
GHGs.
    (iii) Controlled emissions using Sec. 98.123(b)(4). If you use 
Sec. 98.123(b)(4) to estimate the mass of fluorine in destroyed or 
recaptured streams, and if the emissions from the process vent are 
routed through a destruction device, characterize the process vent's 
emissions monthly (or more frequently) using the monthly (or more 
frequent) measurements under paragraphs (b)(1)(iii) and (b)(2)(i) 
through (iii) of this section. Apply the destruction efficiency 
demonstrated for each fluorinated GHG in the destroyed stream to that 
fluorinated GHG. Exclude from the characterization fluorine-containing 
compounds that are not fluorinated GHGs.
    (iv) Emissions characterization frequency. You must repeat emission 
characterizations performed under paragraph (b)(4)(i) and (ii) of this 
section under paragraph (b)(4)(iv)(A) or (B) of this section, whichever 
occurs first:
    (A) 10-year revision. Repeat the emission characterization every 10 
years. In the calculations under Sec. 98.123, apply the revised 
emission characterization to the process activity that occurs after the 
revision.
    (B) Operating scenario change that affects the emission 
characterization. For planned operating scenario changes, you must 
estimate and compare the emission calculation factors for the changed 
operating scenario and for the original operating scenario whose process 
vent specific emission factor was measured. Use the engineering 
calculations and assessments specified in Sec. 98.123(c)(4). If the 
share of total fluorine-containing compound emissions represented by any 
fluorinated GHG changes under the changed operating scenario by 15 
percent or more of the total, relative to the previous operating 
scenario (this includes the cumulative change in the emission 
calculation factor since the last emissions test), you must repeat the 
emission characterization. Perform the emission characterization before 
February 28 of the year that immediately follows the change. In the 
calculations under Sec. 98.123, apply the revised emission 
characterization to the process activity that occurs after the operating 
scenario change.
    (v) Subsequent measurements. If a process vent with fluorinated GHG 
emissions less than 25,000 metric tons CO2e, per Sec. 
98.123(c)(2), is later found to have fluorinated GHG emissions of 25,000 
metric tons CO2e or greater, you must perform an emission 
characterization under this paragraph during the following year.
    (5) Emissions characterization: Process vents emitting less than 
25,000 metric tons CO2e. To characterize emissions from any process vent

[[Page 773]]

emitting less than 25,000 metric tons CO2e, comply with 
paragraphs (b)(5)(i) through (iii) of this section, as appropriate. Only 
fluorine-containing reactants, products, and by-products that occur in a 
stream in greater than trace concentrations must be monitored under this 
paragraph.
    (i) Uncontrolled emissions. If emissions from the process vent are 
not routed through a destruction device, emission measurements must 
consist of sampling and analysis of emissions at the process vent or 
stack, sampling and analysis of emitted streams before the process vent, 
previous test results, provided the tests are representative of current 
operating conditions of the process, or bench-scale or pilot-scale test 
data representative of the process operating conditions.
    (ii) Controlled emissions using Sec. 98.123(b)(15). If you use 
Sec. 98.123(b)(15) to estimate the total mass of fluorine in destroyed 
or recaptured streams, and if the emissions from the process vent are 
routed through a destruction device, characterize emissions as specified 
in paragraph (b)(5)(i) of this section before the destruction device. 
Apply the destruction efficiency demonstrated for each fluorinated GHG 
in the destroyed stream to that fluorinated GHG. Exclude from the 
characterization fluorine-containing compounds that are not fluorinated 
GHGs.
    (iii) Controlled emissions using Sec. 98.123(b)(4). If you use 
Sec. 98.123(b)(4) to estimate the mass of fluorine in destroyed or 
recaptured streams, and if the emissions from the process vent are 
routed through a destruction device, characterize the process vent's 
emissions monthly (or more frequently) using the monthly (or more 
frequent) measurements under paragraphs (b)(1)(iii) and (b)(2)(i) 
through (iii) of this section. Apply the destruction efficiency 
demonstrated for each fluorinated GHG in the destroyed stream to that 
fluorinated GHG. Exclude from the characterization fluorine-containing 
compounds that are not fluorinated GHGs.
    (6) Emissions characterization: Emissions not accounted for by 
process vent estimates. Calculate the weighted average emission 
characterization across the process vents before any destruction 
devices. Apply the weighted average emission characterization for all 
the process vents to any fluorine emissions that are not accounted for 
by process vent estimates.
    (7) Impurities in reactants. If any fluorine-containing impurity is 
fed into a process along with a reactant (or other input) in greater 
than trace concentrations, this impurity shall be monitored under this 
section and included in the calculations under Sec. 98.123 in the same 
manner as reactants fed into the process, fed into the destruction 
device, recaptured, or emitted, except the concentration of the impurity 
in the mass fed into the process shall be measured, and the mass of the 
impurity fed into the process shall be calculated as the product of the 
concentration of the impurity and the mass fed into the process. The 
mass of the reactant fed into the process may be reduced to account for 
the mass of the impurity.
    (8) Alternative to error calculation. As an alternative to 
calculating the relative and absolute errors associated with the 
estimate of emissions under Sec. 98.123(b), you may comply with the 
precision, accuracy, measurement and calculation frequency, and 
fluorinated GHG throughput requirements of paragraph (b)(8)(i) through 
(iv) of this section.
    (i) Mass measurements. Measure the masses specified in paragraph 
(b)(1) of this section using flowmeters, weigh scales, or a combination 
of volumetric and density measurements with accuracies and precisions of 
0.2 percent of full scale or better.
    (ii) Concentration measurements. Measure the concentrations 
specified in paragraph (b)(2) or (3) of this section, as applicable, 
using analytical methods with accuracies and precisions of 10 percent or better.
    (iii) Measurement and calculation frequency. Perform the mass 
measurements specified in paragraph (b)(1) of this section and the 
concentration measurements specified in paragraph (b)(2) or (3) of this 
section, as applicable, at least weekly, and calculate emissions at 
least weekly.
    (iv) Fluorinated-GHG throughput limit. You may use the alternative 
to the error calculation specified in paragraph (b)(8) of this section 
only if the total annual CO2-equivalent fluorinated GHG 
throughput of the process is 500,000 mtCO2e or less. The 
total throughput is the sum of the masses of the fluorinated GHG 
reactants, products, and by-products fed into and generated by the 
process. To convert these masses to CO2e, use Equation A-1 of 
Sec. 98.2. For fluorinated GHGs whose GWPs are not listed in Table A-1 
to subpart A of this part, use a default GWP of 2,000.

           Subpart O_HCFC	22 Production and HFC	23 Destruction



Sec. 98.150  Definition of the source category.

    The HCFC-22 production and HFC-23 destruction source category 
consists of HCFC-22 production processes and HFC-23 destruction 
processes.
    (a) An HCFC-22 production process produces HCFC-22 
(chlorodifluoromethane, or CHClF2) from chloroform 
(CHCl3) and hydrogen fluoride (HF).
    (b) An HFC-23 destruction process is any process in which HFC-23 
undergoes destruction. An HFC-23 destruction process may or may not be 
co-located with an HCFC-22 production process at the same facility.



Sec. 98.151  Reporting threshold.

    You must report GHG emissions under this subpart if your facility 
contains an HCFC-22 production or HFC-23 destruction process and the 
facility meets the requirements of either Sec. 98.2(a)(1) or (a)(2).

[[Page 778]]



Sec. 98.152  GHGs to report.

    (a) You must report under subpart C of this part (General Stationary 
Fuel Combustion Sources) the emissions of CO2, 
CH4, and N2O from each stationary combustion unit 
following the requirements of subpart C.
    (b) You must report HFC-23 emissions from HCFC-22 production 
processes and HFC-23 destruction processes.



Sec. 98.153  Calculating GHG emissions.

    (a) The mass of HFC-23 generated from each HCFC-22 production 
process shall be estimated by using one of two methods, as applicable:
    (1) Where the mass flow of the combined stream of HFC-23 and another 
reaction product (e.g., HCl) is measured, multiply the weekly (or more 
frequent) HFC-23 concentration measurement (which may be the average of 
more frequent concentration measurements) by the weekly (or more 
frequent) mass flow of the combined stream of HFC-23 and the other 
product. To estimate annual HFC-23 production, sum the weekly (or more 
frequent) estimates of the quantities of HFC-23 produced over the year. 
This calculation is summarized in Equation O-1 of this section:
[GRAPHIC] [TIFF OMITTED] TR30OC09.051

Where:

G23 = Mass of HFC-23 generated annually (metric tons).
c23 = Fraction HFC-23 by weight in HFC-23/other product 
          stream.
Fp = Mass flow of HFC-23/other product stream during the 
          period p (kg).
p = Period over which mass flows and concentrations are measured.
n = Number of concentration and flow measurement periods for the year.
10-3 = Conversion factor from kilograms to metric tons.

    (2) Where the mass of only a reaction product other than HFC-23 
(either HCFC-22 or HCl) is measured, multiply the ratio of the weekly 
(or more frequent) measurement of the HFC-23 concentration and the 
weekly (or more frequent) measurement of the other product concentration 
by the weekly (or more frequent) mass produced of the other product. To 
estimate annual HFC-23 production, sum the weekly (or more frequent) 
estimates of the quantities of HFC-23 produced over the year. This 
calculation is summarized in Equation O-2 of this section, assuming that 
the other product is HCFC-22. If the other product is HCl, HCl may be 
substituted for HCFC-22 in Equations O-2 and O-3 of this section.
[GRAPHIC] [TIFF OMITTED] TR30OC09.052

Where:

G23 = Mass of HFC-23 generated annually (metric tons).
c23 = Fraction HFC-23 by weight in HCFC-22/HFC-23 stream.
c22 = Fraction HCFC-22 by weight in HCFC-22/HFC-23 stream.
P22 = Mass of HCFC-22 produced over the period p (kg), 
          calculated using Equation O-3 of this section.
p = Period over which masses and concentrations are measured.
n = Number of concentration and mass measurement periods for the year.
10-3 = Conversion factor from kilograms to metric tons.

    (b) The mass of HCFC-22 produced over the period p shall be 
estimated by using Equation O-3 of this section:
[GRAPHIC] [TIFF OMITTED] TR30OC09.053

Where:

P22 = Mass of HCFC-22 produced over the period p (kg).
O22 = mass of HCFC-22 that is measured coming out of the 
          Production process over the period p (kg).
U22 = Mass of used HCFC-22 that is added to the production 
          process upstream of the output measurement over the period p 
          (kg).
LF = Factor to account for the loss of HCFC-22 upstream of the 
          measurement. The value for LF shall be determined pursuant to 
          Sec. 98.154(e).

    (c) For HCFC-22 production facilities that do not use a destruction 
device or that have a destruction device that is not directly connected 
to the HCFC-22 production equipment, HFC-23 emissions shall be estimated 
using Equation O-4 of this section:

[[Page 779]]

[GRAPHIC] [TIFF OMITTED] TR30OC09.054

Where:

accuracy and precision of 1.0 percent of full scale or better. If the 
mass in paragraph (c) of this section is measured by weighing containers 
that include returned heels as well as newly produced fluorinated GHGs, 
the returned heels shall be considered used fluorinated HCFC-22 for 
purposes of this paragraph (d) of this section and Sec. 98.153(b).
    (e) The loss factor LF in Equation O-3 of this subpart for the mass 
of HCFC-22 produced shall have the value 1.015 or another value that can 
be demonstrated, to the satisfaction of the Administrator, to account 
for losses of HCFC-22 between the reactor and the point of measurement 
at the facility where production is being estimated.
    (f) The mass of HFC-23 sent off site for sale shall be measured at 
least weekly (when being packaged) using flowmeters, weigh scales, or a 
combination of volumetric and density measurements with an accuracy and 
precision of 1.0 percent of full scale or better.

measured at least weekly (when being packaged) using flowmeters, weigh 
scales, or a combination of volumetric and density measurements with an

measured mass includes more than trace concentrations of materials other 
than HFC-23, the concentration of the fluorinated GHG shall be measured 
at least weekly using

[[Page 781]]

equipment and methods (e.g., gas chromatography) with an accuracy and 
precision of 5 percent or better at the concentrations of the process 
samples. This concentration (mass fraction) shall be multiplied by the

1.0 percent of full scale or better.
    (i) The number of sources of equipment type t with screening values 
greater than or equal to 10,000 ppmv shall be determined using EPA 
Method 21 at 40 CFR part 60, appendix A-7, and defining a leak as 
follows:

facilities that use a destruction device connected to the HCFC-22 
production equipment shall conduct emissions tests at process vents at 
least once every five years or after significant changes to the process. 
Emissions tests shall be conducted in accordance with EPA Method 18 at 
40 CFR part 60, appendix A-6, under conditions that are typical for the 
production process at the facility. The sensitivity of the tests shall 
be sufficient to detect an emission rate that would result in annual 
emissions of 200 kg of HFC-23 if sustained over one year.
    (l) For purposes of Equation O-9 of this subpart, the destruction 
efficiency must be equated to the destruction efficiency determined 
during a new or previous performance test of the destruction device. 
HFC-23 destruction facilities shall conduct annual measurements of HFC-
23 concentrations at the outlet of the destruction device in accordance 
with EPA Method 18 at 40 CFR part 60, appendix A-6. Three samples shall 
be taken under conditions that are typical for the production process 
and destruction device at the facility, and the average concentration of 
HFC-23 shall be determined. The sensitivity of the concentration 
measurement shall be sufficient to detect an outlet concentration equal 
to or less than the outlet concentration determined in the destruction 
efficiency performance test. If the concentration measurement indicates 
that the HFC-23 concentration is less than or equal to that measured 
during the performance test that is the basis for the destruction 
efficiency, continue to use the previously determined destruction 
efficiency. If the concentration measurement indicates that the HFC-23 
concentration is greater than that measured during the performance test 
that is the basis for the destruction efficiency, facilities shall 
either:
    (1) Substitute the higher HFC-23 concentration for that measured 
during the destruction efficiency performance test and calculate a new 
destruction efficiency, or
    (2) Estimate the mass emissions of HFC-23 from the destruction 
device based on the measured HFC-23 concentration and volumetric flow 
rate determined by measurement of volumetric flow rate using EPA Method 
2, 2A, 2C,2D, or 2F at 40 CFR part 60, appendix A-1, or Method 26 at 40 
CFR part 60, appendix A-2. Determine the mass rate of HFC-23 into the 
destruction device by measuring the HFC-23 concentration and volumetric 
flow rate at the inlet or by a metering device for HFC-23 sent to the 
device. Determine a new destruction efficiency based on the mass flow 
rate of HFC-23 into and out of the destruction device.
    (m) HCFC-22 production facilities shall account for HFC-23 
generation and emissions that occur as a result of

[[Page 782]]

startups, shutdowns, and malfunctions, either recording HFC-23 
generation and emissions during these events, or documenting that these 
events do not result in significant HFC-23 generation and/or emissions.
    (n) The mass of HFC-23 fed into the destruction device shall be 
measured at least weekly using flow meters, weigh scales, or a 
combination of volumetric and density measurements with an accuracy and 
precision of 1.0 percent of full scale or better. If the measured mass 
includes more than trace concentrations of materials other than HFC-23, 
the concentrations of the HFC-23 shall be measured at least weekly using 
equipment and methods (e.g., gas chromatography) with an accuracy and 
precision of 5 percent or better at the concentrations of the process 
samples. This concentration (mass fraction) shall be multiplied by the 
mass measurement to obtain the mass of the HFC-23 destroyed.
    (o) In their estimates of the mass of HFC-23 destroyed, HFC-23 
destruction facilities 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 destruction device manufacturer specifications.
    (p) Calibrate all flow meters, weigh scales, and combinations of 
volumetric and density measures using NIST-traceable standards and 
suitable methods published by a consensus standards organization (e.g., 
ASTM, ASME, ISO, or others). Recalibrate all flow meters, weigh scales, 
and combinations of volumetric and density measures at the minimum 
frequency specified by the manufacturer.
    (q) All gas chromatographs used to determine the concentration of 
HFC-23 in process streams shall be calibrated at least monthly through 
analysis of certified standards (or of calibration gases prepared from a 
high-concentration certified standard using a gas dilution system that 
meets the requirements specified in Method 205 at 40 CFR part 51, 
appendix M) with known HFC-23 concentrations that are in the same range 
(fractions by mass) as the process samples.

Sec. 98.155  Procedures for estimating missing data.

    (a) A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation or if a required process sample is 
not taken), a substitute data value for the missing parameter shall be 
used in the calculations, according to the following requirements:
    (1) For each missing value of the HFC-23 or HCFC-22 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. If, for a particular 
parameter, no quality-assured data are available prior to the missing 
data incident, the substitute data value shall be the first quality-
assured value obtained after the missing data period.
    (2) For each missing value of the product stream mass flow or 
product mass, the substitute value of that parameter shall be a 
secondary product measurement where such a measurement is available. If 
that measurement is taken significantly downstream of the usual mass 
flow or mass measurement (e.g., at the shipping dock rather than near 
the reactor), the measurement shall be multiplied by 1.015 to compensate 
for losses. 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.

the outlet of the device. If the concentration of HFC-23 is below the 
detection limit of the measuring device, report the detection limit and 
that the concentration is below the detection limit.
    (d) If the HFC-23 concentration measured pursuant to Sec. 98.154(l) 
is greater than that measured during the performance test that is the 
basis for the destruction efficiency (DE), the facility shall report the 
method used to calculate the revised destruction efficiency, specifying 
whether Sec. 98.154(l)(1) or (2) has been used for the calculation.
    (e) By March 31, 2011 or within 60 days of commencing HFC-23 
destruction, HFC-23 destruction facilities shall submit a one-time 
report including the following information for each destruction process:

    (3) The methods used to record the mass of HFC-23 destroyed.
    (4) The name of other relevant federal or state regulations that may 
apply to the destruction process.

efficiency or the methods used to record volume destroyed, then these 
changes must be reflected in a revision to this report. The revised 
report must be submitted to EPA within 60 days of the change.

vented through the same stack as any combustion unit or process 
equipment that reports CO2 emissions using a CEMS that 
complies with the Tier 4 Calculation Methodology in subpart C of this 
part (General Stationary Fuel Combustion Sources), then the calculation 
methodology in paragraph (b) of this section shall not be used to

Sec. 98.164  Monitoring and QA/QC requirements.

    The GHG emissions data for hydrogen production process units must be 
quality-assured as specified in paragraphs (a) or (b) of this section, 
as appropriate for each process unit:
    (a) If a CEMS is used to measure GHG emissions, then the facility 
must comply with the monitoring and QA/QC procedures specified in Sec. 
98.34(c).
    (b) If a CEMS is not used to measure GHG emissions, then you must:

Sec. 98.165  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation), a substitute data value for the 
missing parameter must be used in the calculations as specified in 
paragraphs (a), (b), and (c) of this section:
    (a) For each missing value of the monthly fuel and feedstock 
consumption, the substitute data value must be the best available 
estimate of the fuel and feedstock consumption, based on all available 
process data (e.g., hydrogen production, electrical load, and operating 
hours). You must document and keep records of the procedures used for 
all such estimates.
    (b) For each missing value of the carbon content or molecular weight 
of the fuel and feedstock, the substitute data value must be the 
arithmetic average of the quality-assured values of carbon contents or 
molecular weight of the fuel and feedstock immediately preceding and 
immediately following the missing data incident. If no quality-assured 
data on carbon contents or molecular weight of the fuel and feedstock 
are available prior to the missing data incident, the substitute data 
value must be the first quality-assured value for carbon contents or 
molecular weight of the fuel and feedstock obtained after the missing 
data period. You must document and keep records of the procedures used 
for all such estimates.
    (c) For missing CEMS data, you must use the missing data procedures 
in Sec. 98.35.



Sec. 98.166  Data reporting requirements.

    In addition to the information required by Sec. 98.3(c), each 
annual report must contain the information specified in paragraphs (a) 
or (b) of this section, as appropriate, and paragraphs (c) through (e)

or specialty (low carbon) steel, develop an emission factor for the 
production of both types of steel.
    (ii) For the exhaust from continuously charged EAFs, sample the 
exhaust for a period spanning at least three hours. For EAFs that 
produce both carbon steel and stainless or specialty (low carbon) steel, 
develop an emission factor for the production of both types of steel.

    (6) If your process operates under different conditions as part of 
normal operations in such a manner that CO2 emissions change 
by more than 20 percent (e.g., routine changes in the carbon content of 
the sinter feed or change in grade of product), you must perform 
emission testing and develop separate emission factors for these 
different operating conditions and determine emissions based on the 
number of hours the process operates and the production or feed rate (as 
applicable) at each specific different condition.
    (7) If your EAF and decarburization vessel exhaust to a common 
emission control device and stack, you must sample each process in the 
ducts before

[[Page 797]]

the emissions are combined, sample each process when only one process is 
operating, or sample the combined emissions when both processes are 
operating and base the site-specific emission factor on the steel 
production rate of the EAF.
    (8) The results of a performance test must include the analysis of 
samples, determination of emissions, and raw data. The performance test 
report must contain all information and data used to derive the emission 
factor.

calculations as specified in the paragraphs (a) and (b) of this section. 
You must follow the missing data procedures in Sec. 98.255(b) of 
subpart Y (Petroleum Refineries) of this part for flares burning coke 
oven gas or blast furnace gas. You must document and keep records of the 
procedures used for all such estimates.

availability is required for the carbon content of inputs and outputs 
for facilities that estimate emissions using the carbon mass balance 
procedure in Sec. 98.173(b)(1) or facilities that estimate emissions 
using the site-specific emission factor procedure in Sec. 98.173(b)(2).
    (b) For missing records of the monthly mass or volume of carbon-
containing inputs and outputs using the carbon mass balance procedure in 
Sec. 98.173(b)(1), the substitute data value must be based on the best 
available estimate of the mass of the input or output material from all 
available process data or data used for accounting purposes.

Sec. 98.195  Procedures for estimating missing data.

    For the procedure in Sec. 98.193(b)(1), a complete record of all 
measured parameters used in the GHG emissions calculations is required 
(e.g., oxide content, quantity of lime products, etc.). 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 (a) or (b) of this section. You 
must document and keep records of the procedures used for all such 
estimates.
    (a) For each missing value of the quantity of lime produced (by lime 
type), and quantity of calcined byproduct or waste produced and sold, 
the substitute data value shall be the best available estimate based on 
all available process data or data used for accounting purposes.
    (b) For missing values related to the CaO and MgO content, you must 
conduct a new composition test according to the standard methods in 
Sec. 98.194 (c)(1) or (c)(2).

X = Each cover gas or carrier gas that is a GHG.

    (2) To estimate emissions of cover gases or carrier gases by 
monitoring changes in the masses of individual containers as their 
contents are used, emissions of each cover gas or carrier gas shall be 
estimated using Equation T-2 of this section:

    (c) If a facility has mass flow controllers (MFC) and the capacity 
to track and record MFC measurements to estimate total gas usage, the 
mass of each cover or carrier gas monitored may be

[[Page 818]]

used as the mass of cover or carrier gas consumed (Qp), in kg 
for period p in Equation T-2 of this section.



Sec. 98.204  Monitoring and QA/QC requirements.

    (a) For calendar year 2011 monitoring, the facility may submit a 
request to the Administrator to use one or more best available 
monitoring methods as listed in Sec. 98.3(d)(1)(i) through (iv). The 
request must be submitted no later than October 12, 2010 and must 
contain the information in Sec. 98.3(d)(2)(ii). To obtain approval, the 
request must demonstrate to the Administrator's satisfaction that it is 
not reasonably feasible to acquire, install, and operate a required 
piece of monitoring equipment by January 1, 2011. The use of best 
available monitoring methods will not be approved beyond December 31, 
2011.
    (b) Emissions (consumption) of cover gases and carrier gases may be 
estimated by monitoring the changes in container weights and inventories 
using Equation T-1 of this subpart, by monitoring the changes in 
individual container weights as the contents of each container are used 
using Equations T-2 and T-3 of this subpart, or by monitoring the mass 
flow of the pure cover gas or carrier gas into the gas distribution 
system. Emissions must be estimated at least annually.
    (c) When estimating emissions by monitoring the mass flow of the 
pure cover gas or carrier gas into the gas distribution system, you must 
use gas flow meters, or mass flow controllers, with an accuracy of 1 
percent of full scale or better.
    (d) When estimating emissions using Equation T-1 of this subpart, 
you must ensure that all the quantities required by Equation T-1 of this 
subpart have been measured using scales or load cells with an accuracy 
of 1 percent of full scale or better, accounting for the tare weights of 
the containers. You may accept gas masses or weights provided by the gas 
supplier e.g., for the contents of containers containing new gas or for 
the heels remaining in containers returned to the gas supplier) if the 
supplier provides documentation verifying that accuracy standards are 
met; however you remain responsible for the accuracy of these masses or 
weights under this subpart.
    (e) When estimating emissions using Equations T-2 and T-3 of this 
subpart, you must monitor and record container identities and masses as 
follows:
    (1) Track the identities and masses of containers leaving and 
entering storage with check-out and check-in sheets and procedures. The 
masses of cylinders returning to storage shall be measured immediately 
before the cylinders are put back into storage.
    (2) Ensure that all the quantities required by Equations T-2 and T-3 
of this subpart have been measured using scales or load cells with an 
accuracy of 1 percent of full scale or better, accounting for the tare 
weights of the containers. You may accept gas masses or weights provided 
by the gas supplier e.g., for the contents of cylinders containing new 
gas or for the heels remaining in cylinders returned to the gas 
supplier) if the supplier provides documentation verifying that accuracy 
standards are met; however, you remain responsible for the accuracy of 
these masses or weights under this subpart.
    (f) All flowmeters, scales, and load cells used to measure 
quantities that are to be reported under this subpart shall be 
calibrated using calibration procedures specified by the flowmeter, 
scale, or load cell manufacturer. Calibration shall be performed prior 
to the first reporting year. After the initial calibration, 
recalibration shall be performed at the minimum frequency specified by 
the manufacturer.



Sec. 98.205  Procedures for estimating missing data.

    (a) A complete record of all measured parameters used in the GHG 
emission calculations is required. Therefore, whenever a quality-assured 
value of a required parameter is unavailable, a substitute data value 
for the missing parameter will be used in the calculations as specified 
in paragraph (b) of this section.
    (b) Replace missing data on the emissions of cover or carrier gases 
by multiplying magnesium production during the missing data period by 
the average cover or carrier gas usage rate from the most recent period 
when operating

[[Page 819]]

conditions were similar to those for the period for which the data are 
missing. Calculate the usage rate for each cover or carrier gas using 
Equation T-4 of this section:
[GRAPHIC] [TIFF OMITTED] TR12JY10.003

Where:

RGHG = The usage rate for a particular cover or carrier gas 
          over the period of comparable operation (metric tons gas/
          metric ton Mg).
CGHG = The consumption of that cover or carrier gas over the 
          period of comparable operation (kg).
Mg = The magnesium produced or fed into the process over the period of 
          comparable operation (metric tons).
0.001 = Conversion factor from kg to metric tons.

    (c) If the precise before and after weights are not available, it 
should be assumed that the container was emptied in the process (i.e., 
quantity purchased should be used, less heel).



Sec. 98.206  Data reporting requirements.

    In addition to the information required by Sec. 98.3(c), each 
annual report must include the following information at the facility

minute) for each production unit and composition in percent by volume.
    (e) For any missing data, you must report the length of time the 
data were missing for each cover gas or carrier gas, the method used to 
estimate emissions in their absence, and the quantity of emissions 
thereby estimated.

pressure swing adsorber used as fuel supplement), or sulfur recovery 
plant, using any of the calculation methods described in this paragraph

    (1) Calculation Method 1. If you operate and maintain a continuous 
emissions monitoring system (CEMS) that has both a CO2 
concentration monitor and volumetric flow rate monitor, you must 
calculate CO2 emissions under this subpart by following the 
Tier 4 Calculation Method and all associated calculation, quality 
assurance, reporting, and recordkeeping requirements for Tier 4 in

install a CO2 concentration monitor and a volumetric flow 
rate monitor that comply with all of the requirements specified for the 
Tier 4 Calculation Method in subpart C of this part (General Stationary 
Fuel Combustion Sources). The calculation and reporting of 
CH4 and N2O emissions is not required as part of

you may calculate emissions using any standard simulation software 
package, such as AspenTech HYSYS[supreg], or API 4679 AMINECalc, that 
uses the Peng-Robinson equation of state and speciates CO2 
emissions. A minimum of the following, determined for typical operating 
conditions over the calendar year by engineering estimate and process 
knowledge based on best available data, must be used to characterize 
emissions:
    (i) Natural gas feed temperature, pressure, and flow rate.
    (ii) Acid gas content of feed natural gas.
    (iii) Acid gas content of outlet natural gas.
    (iv) Unit operating hours, excluding downtime for maintenance or

recovered and transferred outside the facility.
    (e) Dehydrator vents. For dehydrator vents, calculate annual 
CH4 and CO2 emissions using the applicable 
calculation methods described in paragraphs (e)(1) through (e)(4) of 
this section. If emissions from dehydrator vents are routed to a vapor 
recovery system, you must adjust the emissions downward according to

HYSYS[supreg] or GRI-GLYCalc \TM\, that uses the Peng-Robinson equation 
of state to calculate the equilibrium coefficient, speciates 
CH4 and CO2 emissions from dehydrators, and has 
provisions to include regenerator control devices, a separator flash 
tank, stripping gas and a gas injection pump or gas assist pump. The

    (4) Calculate CH4 and CO2 volumetric and mass 
emissions from volumetric natural gas emissions using calculations in 
paragraphs (u) and (v) of this section.
    (g) Well venting during completions and workovers with hydraulic 
fracturing. Calculate annual volumetric natural gas emissions from gas 
well and oil well venting during completions and workovers involving 
hydraulic fracturing using Equation W-10A or Equation W-10B of this 
section. Equation W-10A applies to well venting when the gas flowback 
rate is measured from a specified number of example completions or 
workovers and Equation W-10B applies when the gas flowback vent or flare 
volume is measured for each completion or workover. Completion and 
workover activities are separated into two periods, an initial period 
when flowback is routed to open pits or tanks and a subsequent period 
when gas content is sufficient to route the flowback to a separator or 
when the gas content is sufficient to allow measurement by the devices 
specified in paragraph (g)(1) of this section, regardless of whether a 
separator is actually utilized. If you elect to use Equation W-10A, you 
must follow the procedures specified in paragraph (g)(1). If you elect 
to use Equation W-10B, you must use a recording flow meter installed on 
the vent line, downstream of a separator and ahead of a flare or vent, 
to measure the gas flowback. For either equation, emissions must be 
calculated separately for completions and workovers, for each sub-basin, 
and for each well type combination identified in paragraph (g)(2) of 
this section. You must calculate CH4 and CO2 
volumetric and mass emissions as specified in paragraph (g)(3) of this 
section. If emissions from well venting during completions and workovers 
with hydraulic fracturing are routed to a flare, you must calculate 
CH4, CO2, and N2O annual emissions as 
specified in paragraph (g)(4) of this section.

          where gas vented or flared for the completion or workover, in 
          hours, for each well, p, in a sub-basin and well type 
          combination during the reporting year. This may include non-

          basin and well type combination during the reporting year. 
          This may include non-contiguous periods of routing to open

          ceases to produce fluids to the surface.

          sufficient quantities of gas are present to enable separation,

          combination, calculated using procedures specified in 
          paragraph (g)(1)(iii) of this section.

          basin and well type combination. If applicable,

          procedures specified in paragraph (g)(1)(vii) of this section.
EnFs,p = Volume of N2 injected gas in cubic feet

          to methods described in Sec. 98.234(b), or by using receipts 
          of gas purchases that are used for the energized fracture job 
          or injection during flowback. Convert to standard conditions 
          using paragraph (t) of this section. If the fracture process 
          did not inject gas into the reservoir or if the injected gas 
          is CO2 then EnFs,p is 0.
FVs,p = Flow volume of vented or flared gas for each well, p, 
          in standard cubic feet measured using a recording flow meter 
          (digital or analog) on the vent line to measure gas flowback

          of the completion or workover according to methods set forth 
          in Sec. 98.234(b).

    (1) If you elect to use Equation W-10A of this section on gas wells, 
you must use Calculation Method 1 as specified in paragraph (g)(1)(i) of 
this section, or Calculation Method 2 as specified in paragraph 
(g)(1)(ii) of this section, to determine the value of FRMs 
and FRMi. If you elect to use Equation W-10A of this section 
on oil wells, you must use Calculation Method 1 as specified in 
paragraph (g)(1)(i) to determine the value of FRMs and 
FRMi. These values must be based on the flow rate for 
flowback gases, once sufficient gas is present to enable separation. The 
number of measurements or calculations required to estimate 
FRMs and FRMi must be determined individually for 
completions and workovers per sub-basin and well type combination as 
follows: Complete measurements or calculations for at least one 
completion or workover for less than or equal to 25 completions or 
workovers for each well type combination within a sub-basin; complete 
measurements or calculations for at least two completions or workovers 
for 26 to 50 completions or workovers for each sub-basin and well type 
combination; complete measurements or calculations for at least three 
completions or workovers for 51 to 100 completions or workovers for each 
sub-basin and well type combination; complete measurements or 
calculations for at least four completions or workovers for 101 to 250 
completions or workovers for each sub-basin and well type combination; 
and complete measurements or calculations for at least five completions 
or workovers for greater than 250 completions or workovers for each sub-
basin and well type combination.
    (i) Calculation Method 1. You must use Equation W-12A of this 
section as specified in paragraph (g)(1)(iii) of this section to 
determine the value of FRMs. You must use Equation W-12B of 
this section as specified in paragraph (g)(1)(iv) of this section to 
determine the value of FRMi. The procedures specified in 
paragraphs (g)(1)(v) and (vi) of this section also apply. When making 
gas flowback measurements for use in Equations W-12A and W-12B of this 
section, you must use a recording flow meter (digital or analog) 
installed on the vent line, downstream of a separator and ahead of a 
flare or vent, to measure the gas flowback rates in units of standard 
cubic feet per hour according to methods set forth in Sec. 98.234(b).
    (ii) Calculation Method 2 (for gas wells). You must use Equation W-
12A as specified in paragraph (g)(1)(iii) of this section to determine 
the value of FRMs. You must use Equation W-12B as specified 
in paragraph (g)(1)(iv) of this section to determine the value of 
FRMi. The procedures specified in paragraphs (g)(1)(v) and 
(vi) also apply. When calculating the flowback rates for use in 
Equations W-12A and W-12B of this section based on well parameters, you 
must record the well flowing pressure immediately upstream (and 
immediately downstream in subsonic flow) of a well choke according to

[[Page 843]]

methods set forth in Sec. 98.234(b) to calculate the well flowback. The 
upstream pressure must be surface pressure and reservoir pressure cannot 
be assumed. The downstream pressure must be measured after the choke and 
atmospheric pressure cannot be assumed. Calculate flowback rate using 
Equation W-11A of this section for subsonic flow or Equation W-11B of 
this section for sonic flow. You must use best engineering estimates 
based on best available data along with Equation W-11C of this section 
to determine whether the predominant flow is sonic or subsonic. If the 
value of R in Equation W-11C of this section is greater than or equal to 
2, then flow is sonic; otherwise, flow is subsonic. Convert calculated 
FRa values from actual conditions upstream of the restriction 
orifice to standard conditions (FRs,p and FRi,p) 
for use in Equations W-12A and W-12B of this section using Equation W-33 
in paragraph (t) of this section.

Where:

FRMs = Ratio of average gas flowback rate, during the period 
          of time when sufficient quantities of gas are present to

          separation period in standard cubic feet per hour for well(s)

          measured and calculated FRa values from actual 
          conditions upstream of the restriction orifice 
          (FRa) to standard conditions (FRs,p) for 
          each well p using Equation W-33 in paragraph (t) of this 
          section. You may not use flow volume as used in Equation W-10B 
          of this section converted to a flow rate for this parameter.
PRs,p = Average gas production flow rate during the first 30 
          days of production after completions of newly drilled wells or 
          well workovers using hydraulic fracturing, in standard cubic

          basin and well type combination. For oil wells for which 
          production is not measured continuously during the first 30 
          days of production, the average flow rate may be based on 
          individual well production tests conducted within the first 30 
          days of production. Alternatively, if applicable, 
          PRs,p may be calculated for oil wells using 
          procedures specified in paragraph (g)(1)(vii) of this section.
N = Number of measured or calculated well completions or workovers using 
          hydraulic fracturing in a sub-basin and well type combination.

[GRAPHIC] [TIFF OMITTED] TR25NO14.038

Where:

FRMi = Ratio of initial gas flowback rate during well 
          completions and workovers from hydraulic fracturing to 30-day

          cubic feet per hour for well(s), p, for each sub-basin and 
          well type combination. Measured and calculated 
          FRi,p values must be based on flow conditions at 
          the beginning of the separation period and must be expressed 
          at standard conditions.

          days of production after completions of newly drilled wells or 
          well workovers using hydraulic fracturing, in standard cubic 
          feet per hour of each well, p, that was measured in the sub-
          basin and well type combination. For oil wells for which 
          production is not measured continuously during the first 30 
          days of production, the average flow rate may be based on 
          individual well production tests conducted within the first 30

rate during well completions and workovers from hydraulic fracturing to 
30-day gas production rate are applied to all well completions and well 
workovers, respectively, in the sub-basin and well type combination for 
the total number of hours of flowback and for the first 30 day average 
gas production rate for each of these wells.
    (vi) For Equations W-12A and W-12B of this section, calculate new 
flowback rates for well completions and well workovers in each sub-basin 
and well type combination once every two years starting in the first

          the sub-basin and well type combination; oil here refers to 
          hydrocarbon liquids produced of all API gravities.
Vp = Volume of oil produced during the first 30 days of 
          production after completions of newly drilled wells or well 
          workovers using hydraulic fracturing in barrels of each well

98.234(b).
    (2) For paragraphs (g) introductory text and (g)(1) of this section, 
measurements and calculations are completed separately for workovers and 
completions per sub-basin and well type combination. A well type 
combination is a unique combination of the parameters listed in 
paragraphs (g)(2)(i) through (iv) of this section.

completion/workover.
    (iv) Oil well or gas well.
    (3) Calculate both CH4 and CO2 volumetric and 
mass emissions from total natural gas volumetric emissions using 
calculations in paragraphs (u) and (v) of this section.

using paragraphs (u) and (v) of this section.
    (ii) Use the calculation method of flare stacks in paragraph (n) of 
this

[[Page 846]]

section to adjust emissions for the portion of gas flared during well 
completions and workovers using hydraulic fracturing. This adjustment to 
emissions from completions using flaring, versus completions without 
flaring, accounts for the conversion of CH4 to CO2 
in the flare and for the formation on N2O during flaring.

hydraulic fracturing. Calculate annual volumetric natural gas emissions 
from each gas well venting during workovers without hydraulic fracturing 
using Equation W-13A of this section. Calculate annual volumetric

          without hydraulic fracturing.
Es,p = Annual volumetric natural gas emissions in standard 
          cubic feet from gas well venting during well completions 
          without hydraulic fracturing.
p = Well completions 1 through f in a sub-basin.
f = Total number of well completions without hydraulic fracturing in a 
          sub-basin category.
Vp = Average daily gas production rate in standard cubic feet 
          per hour for each well, p, undergoing completion without 
          hydraulic fracturing. This is the total annual gas production 
          volume divided by total number of hours the wells produced to 
          the flow-line. For completed wells that have not established a 
          production rate, you may use the average flow rate from the 
          first 30 days of production. In the event that the well is 
          completed less than 30 days from the end of the calendar year, 
          the first 30 days of the production straddling the current and 
          following calendar years shall be used.
Tp = Time that gas is vented to either the atmosphere or a 
          flare for each well, p, undergoing completion without 
          hydraulic fracturing, in hours during the year.

    (1) Calculate both CH4 and CO2 volumetric 
emissions from natural gas volumetric emissions using calculations in 
paragraph (u) of this section. Calculate both CH4 and 
CO2 mass emissions from volumetric emissions vented to 
atmosphere using calculations in paragraph (v) of this section.
    (2) Calculate annual emissions of CH4, CO2, 
and N2O from gas well venting to flares during well 
completions and workovers not involving hydraulic fracturing as 
specified in paragraphs (h)(2)(i) and (ii) of this section.
    (i) Use the gas well venting volume and gas composition during well 
completions and workovers that are flared as determined using the 
methods specified in paragraphs (h) and (h)(1) of this section.
    (ii) Use the calculation method of flare stacks in paragraph (n) of 
this section to determine emissions from the flare for gas well venting 
to a flare during completions and workovers without hydraulic 
fracturing.
    (i) Blowdown vent stacks. Calculate CO2 and 
CH4 blowdown vent stack emissions from the depressurization 
of

[[Page 847]]

equipment to reduce system pressure for planned or emergency shutdowns 
resulting from human intervention or to take equipment out of service 
for maintenance as specified in either paragraph (i)(2) or (3) of this 
section. You may use the method in paragraph (i)(2) of this section for 
some blowdown vent stacks at your facility and the method in paragraph 
(i)(3) of this section for other blowdown vent stacks at your facility. 
Equipment with a unique physical volume of less than 50 cubic feet as 
determined in paragraph (i)(1) of this section are not subject to the 
requirements in paragraphs (i)(2) through (4) of this section. The 
requirements in this paragraph (i) do not apply to blowdown vent stack 
emissions from depressurizing to a flare, over-pressure relief, 
operating pressure control venting, blowdown of non-GHG gases, and 
desiccant dehydrator blowdown venting before reloading.
    (1) Method for calculating unique physical volumes. You must 
calculate each unique physical volume (including pipelines, compressor 
case or cylinders, manifolds, suction bottles, discharge bottles, and 
vessels) between isolation valves, in cubic feet, by using engineering 
estimates based on best available data.
    (2) Method for determining emissions from blowdown vent stacks 
according to equipment or event type. If you elect to determine 
emissions according to each equipment or event type, using unique 
physical volumes as calculated in paragraph (i)(1) of this section, you 
must calculate emissions as specified in paragraph (i)(2)(i) of this 
section and either paragraph (i)(2)(ii) or, if applicable, paragraph 
(i)(2)(iii) of this section for each equipment or event type. For 
industry segments other than onshore natural gas transmission pipeline, 
equipment or event types must be grouped into the following seven 
categories: Facility piping (i.e., piping within the facility boundary 
other than physical volumes associated with distribution pipelines), 
pipeline venting (i.e., physical volumes associated with distribution 
pipelines vented within the facility boundary), compressors, scrubbers/
strainers, pig launchers and receivers, emergency shutdowns (this 
category includes emergency shutdown blowdown emissions regardless of 
equipment type), and all other equipment with a physical volume greater 
than or equal to 50 cubic feet. If a blowdown event resulted in 
emissions from multiple equipment types and the emissions cannot be 
apportioned to the different equipment types, then categorize the 
blowdown event as the equipment type that represented the largest 
portion of the emissions for the blowdown event. For the onshore natural 
gas transmission pipeline segment, pipeline segments or event types must 
be grouped into the following eight categories: Pipeline integrity work 
(e.g., the preparation work of modifying facilities, ongoing 
assessments, maintenance or mitigation), traditional operations or 
pipeline maintenance, equipment replacement or repair (e.g., valves), 
pipe abandonment, new construction or modification of pipelines 
including commissioning and change of service, operational precaution 
during activities (e.g. excavation near pipelines), emergency shutdowns 
including pipeline incidents as defined in 49 CFR 191.3, and all other 
pipeline segments with a physical volume greater than or equal to 50 
cubic feet. If a blowdown event resulted in emissions from multiple 
categories and the emissions cannot be apportioned to the different 
categories, then categorize the blowdown event in the category that 
represented the largest portion of the emissions for the blowdown event.
    (i) Calculate the total annual natural gas emissions from each 
unique physical volume that is blown down using either Equation W-14A or 
W-14B of this section.

paragraph (j)(2) of this section. For hydrocarbon liquids flowing to 
gas-liquid separators or non-separator equipment or directly to 
atmospheric storage tanks with throughput less than 10 barrels per day, 
use Calculation Method 3 as specified in paragraph (j)(3) of this 
section. If you use Calculation Method 1 or Calculation Method 2 for 
separators, you must also calculate emissions that may have occurred due 
to dump valves not closing properly using the method specified in 
paragraph (j)(6) of this section. If emissions from atmospheric pressure 
fixed roof storage tanks are routed to a vapor recovery system, you must 
adjust the emissions downward according to paragraph (j)(4) of this 
section. If emissions from atmospheric pressure fixed roof storage tanks 
are routed to a flare, you must calculate CH4, 
CO2, and N2O annual emissions as specified in 
paragraph (j)(5) of this section.
    (1) Calculation Method 1. Calculate annual CH4 and 
CO2 emissions from onshore production storage tanks and 
onshore petroleum and natural gas gathering and boosting storage tanks 
using operating conditions in the last gas-liquid separator or non-
separator equipment before liquid transfer to storage tanks. Calculate 
flashing emissions with a software program, such as AspenTech 
HYSYS[supreg] or API 4697 E&P Tank, that uses the Peng-Robinson equation 
of state, models flashing emissions, and speciates CH4 and 
CO2 emissions that will result when the oil from the 
separator or non-separator equipment enters an atmospheric pressure 
storage tank. The following parameters must be determined for typical 
operating conditions over the year by engineering estimate and process 
knowledge based on best available data, and must be used at a minimum to

vapor pressure data are available through your previous analysis, select

annual CH4 and CO2 emissions using the methods in 
paragraph (j)(2)(ii) of this section for wells with annual average daily 
oil production greater than or equal to 10 barrels per day that flow 
directly to atmospheric storage tanks in onshore petroleum and natural 
gas production and onshore petroleum and natural gas gathering and 
boosting (if applicable). Calculate annual CH4 and 
CO2 emissions using the methods in paragraph (j)(2)(iii) of 
this section for non-separator equipment with annual average daily 
hydrocarbon liquids throughput greater than or equal to 10 barrels per 
day that flow directly to atmospheric storage tanks in onshore petroleum 
and natural gas gathering and boosting.
    (i) Flow to storage tank after passing through a separator. Assume 
that all of the CH4 and CO2 in solution at 
separator temperature and pressure is emitted from oil sent to storage 
tanks. You may use an appropriate standard method published by a 
consensus-based standards organization if such a method exists or you 
may use an industry standard practice as described in Sec. 98.234(b) to 
sample and analyze separator oil composition at separator pressure and 
temperature.
    (ii) Flow to storage tank direct from wells. Calculate 
CH4 and CO2 emissions using either of the methods 
in paragraph (j)(2)(ii)(A) or (B) of this section.
    (A) If well production oil and gas compositions are available 
through a previous analysis, select the latest available analysis that 
is representative of produced oil and gas from the sub-basin category 
and assume all of the CH4 and CO2 in both oil and 
gas are emitted from the tank.
    (B) If well production oil and gas compositions are not available, 
use default oil and gas compositions in software programs, such as API 
4697 E&P Tank, that most closely match the well production gas/oil ratio 
and API gravity and assume all of the CH4 and CO2 
in both oil and gas are emitted from the tank.
    (iii) Flow to storage tank direct from non-separator equipment. 
Calculate CH4 and CO2 emissions using either of 
the methods in paragraph (j)(2)(iii)(A) or (B) of this section.

available through a previous analysis, select the latest available 
analysis that is representative of liquid and gas from non-separator 
equipment in the same county and assume all of the CH4 and 
CO2 in both hydrocarbon liquids and gas are emitted from the 
tank.
    (B) If non-separator equipment liquid and gas compositions are not 
available, use default liquid and gas compositions in software programs, 
such as API 4697 E&P Tank, that most closely match the non-separator 
equipment gas/liquid ratio and API gravity and assume all of the 
CH4 and CO2 in both hydrocarbon liquids and gas 
are emitted from the tank.

          (j)(1), (j)(2) and, if applicable, (j)(4) of this section in 
          standard cubic feet per year.

          in open or partially open position.

you must use the measured flow volumes to calculate the flare gas 
emissions. If all of the flare gas is not measured by the existing flow 
measurement device, then the flow not measured can be estimated using 
engineering calculations based on best available data or company 
records. If you do not have a continuous flow measurement device on the 
flare, you can use engineering calculations based on process knowledge, 
company records, and best available data.
    (2) If you have a continuous gas composition analyzer on gas to the 
flare, you must use these compositions in calculating emissions. If you 
do not have a continuous gas composition analyzer on gas to the flare,

gas liquid for all streams.
    (iii) For any industry segment required to report to flare stack 
emissions under Sec. 98.232, when the stream going to the flare is a 
hydrocarbon product stream, such as methane, ethane, propane, butane, 
pentane-plus and mixed light hydrocarbons, then you may use a

          for propane, 4 for butane, and 5 for pentanes-plus).

    (6) Calculate both CH4 and CO2 mass emissions 
from volumetric emissions using calculation in paragraph (v) of this 
section.
    (7) Calculate N2O emissions from flare stacks using 
Equation W-40 in paragraph (z) of this section.
    (8) If you operate and maintain a CEMS that has both a 
CO2 concentration monitor and volumetric flow rate monitor 
for the combustion gases from the flare, you must calculate only 
CO2 emissions for the flare. You must follow the Tier 4 
Calculation Method and all associated calculation, quality assurance, 
reporting, and recordkeeping requirements for Tier 4 in subpart C of 
this part (General Stationary Fuel Combustion Sources). If a CEMS is 
used to calculate flare stack emissions, the requirements specified in 
paragraphs (n)(1) through (7) of this section are not required.
    (9) The flare emissions determined under this paragraph (n) must be 
corrected for flare emissions calculated and reported under other 
paragraphs of this section to avoid double counting of these emissions.
    (o) Centrifugal compressor venting. If you are required to report 
emissions from centrifugal compressor venting as specified in Sec. 
98.232(d)(2), (e)(2), (f)(2), (g)(2), and (h)(2), you must conduct 
volumetric emission measurements specified in paragraph (o)(1) of this 
section using methods specified in paragraphs (o)(2) through (5) of this 
section; perform calculations specified in paragraphs (o)(6) through (9) 
of this section; and calculate CH4 and CO2 mass 
emissions as specified in paragraph (o)(11) of this section. If 
emissions from a compressor source are routed to a flare, paragraphs 
(o)(1) through (11) do not apply and instead you must calculate 
CH4, CO2, and N2O emissions as 
specified in paragraph (o)(12) of this section. If emissions from a 
compressor source are captured for fuel use or are routed to a thermal 
oxidizer, paragraphs (o)(1) through (12) do not apply and instead you 
must calculate and report emissions as specified in subpart C of this 
part. If emissions from a compressor source are routed to vapor 
recovery, paragraphs (o)(1) through (12) do not apply. If you are 
required to report emissions from centrifugal compressor venting at an 
onshore petroleum and natural gas production facility as specified in 
Sec. 98.232(c)(19) or an onshore petroleum and natural gas gathering 
and boosting facility as specified in Sec. 98.232(j)(8), you must 
calculate volumetric emissions as specified in paragraph (o)(10); and 
calculate CH4 and CO2 mass emissions as specified 
in paragraph (o)(11).
    (1) General requirements for conducting volumetric emission 
measurements. You must conduct volumetric emission measurements on each 
centrifugal compressor as specified in this paragraph. Compressor 
sources (as defined in Sec. 98.238) without manifolded vents must use a 
measurement method specified in paragraph (o)(1)(i) or (ii) of this 
section. Manifolded compressor sources (as defined in Sec. 98.238) must 
use a measurement method specified in paragraph (o)(1)(i), (ii), (iii), 
or (iv) of this section.
    (i) Centrifugal compressor source as found measurements. Measure 
venting from each compressor according to either paragraph (o)(1)(i)(A) 
or (B) of this

[[Page 856]]

section at least once annually, based on the compressor mode (as defined 
in Sec. 98.238) in which the compressor was found at the time of 
measurement, except as specified in paragraphs (o)(1)(i)(C) and (D) of 
this section. If additional measurements beyond the required annual 
testing are performed (including duplicate measurements or measurement 
of additional operating modes), then all measurements satisfying the 
applicable monitoring and QA/QC that is required by this paragraph (o) 
must be used in the calculations specified in this section.
    (A) For a compressor measured in operating-mode, you must measure 
volumetric emissions from blowdown valve leakage through the blowdown 
vent as specified in either paragraph (o)(2)(i)(A) or (B) of this 
section and, if the compressor has wet seal oil degassing vents, measure 
volumetric emissions from wet seal oil degassing vents as specified in 
paragraph (o)(2)(ii) of this section.
    (B) For a compressor measured in not-operating-depressurized-mode, 
you must measure volumetric emissions from isolation valve leakage as 
specified in either paragraph (o)(2)(i)(A), (B), or (C) of this section. 
If a compressor is not operated and has blind flanges in place 
throughout the reporting period, measurement is not required in this 
compressor mode.
    (C) You must measure the compressor as specified in paragraph 
(o)(1)(i)(B) of this section at least once in any three consecutive 
calendar years, provided the measurement can be taken during a scheduled 
shutdown. If three consecutive calendar years occur without measuring 
the compressor in not-operating-depressurized-mode, you must measure the 
compressor as specified in paragraph (o)(1)(i)(B) of this section at the 
next scheduled depressurized shutdown. The requirement specified in this 
paragraph does not apply if the compressor has blind flanges in place 
throughout the reporting year. For purposes of this paragraph, a 
scheduled shutdown means a shutdown that requires a compressor to be 
taken off-line for planned or scheduled maintenance. A scheduled 
shutdown does not include instances when a compressor is taken offline 
due to a decrease in demand but must remain available.
    (D) An annual as found measurement is not required in the first year 
of operation for any new compressor that begins operation after as found 
measurements have been conducted for all existing compressors. For only 
the first year of operation of new compressors, calculate emissions 
according to paragraph (o)(6)(ii) of this section.
    (ii) Centrifugal compressor source continuous monitoring. Instead of 
measuring the compressor source according to paragraph (o)(1)(i) of this 
section for a given compressor, you may elect to continuously measure 
volumetric emissions from a compressor source as specified in paragraph 
(o)(3) of this section.
    (iii) Manifolded centrifugal compressor source as found 
measurements. For a compressor source that is part of a manifolded group 
of compressor sources (as defined in Sec. 98.238), instead of measuring 
the compressor source according to paragraph (o)(1)(i), (ii), or (iv) of 
this section, you may elect to measure combined volumetric emissions 
from the manifolded group of compressor sources by conducting 
measurements at the common vent stack as specified in paragraph (o)(4) 
of this section. The measurements must be conducted at the frequency 
specified in paragraphs (o)(1)(iii)(A) and (B) of this section.
    (A) A minimum of one measurement must be taken for each manifolded 
group of compressor sources in a calendar year.
    (B) The measurement may be performed while the compressors are in 
any compressor mode.
    (iv) Manifolded centrifugal compressor source continuous monitoring. 
For a compressor source that is part of a manifolded group of compressor 
sources, instead of measuring the compressor source according to 
paragraph (o)(1)(i), (ii), or (iii) of this section, you may elect to 
continuously measure combined volumetric emissions from the manifolded 
group of compressor sources as specified in paragraph (o)(5) of this 
section.
    (2) Methods for performing as found measurements from individual 
centrifugal

[[Page 857]]

compressor sources. If conducting measurements for each compressor 
source, you must determine the volumetric emissions from blowdown valves 
and isolation valves as specified in paragraph (o)(2)(i) of this 
section, and the volumetric emissions from wet seal oil degassing vents 
as specified in paragraph (o)(2)(ii) of this section.
    (i) For blowdown valves on compressors in operating-mode and for 
isolation valves on compressors in not-operating-depressurized-mode, 
determine the volumetric emissions using one of the methods specified in 
paragraphs (o)(2)(i)(A) through (D) of this section.
    (A) Determine the volumetric flow at standard conditions from the 
blowdown vent using calibrated bagging or high volume sampler according 
to methods set forth in Sec. 98.234(c) and Sec. 98.234(d), 
respectively.
    (B) Determine the volumetric flow at standard conditions from the 
blowdown vent using a temporary meter such as a vane anemometer 
according to methods set forth in Sec. 98.234(b).
    (C) Use an acoustic leak detection device according to methods set 
forth in Sec. 98.234(a)(5).
    (D) You may choose to use any of the methods set forth in Sec. 
98.234(a) to screen for emissions. If emissions are detected using the 
methods set forth in Sec. 98.234(a), then you must use one of the 
methods specified in paragraph (o)(2)(i)(A) through (C) of this section. 
If emissions are not detected using the methods in Sec. 98.234(a), then 
you may assume that the volumetric emissions are zero. For the purposes 
of this paragraph, when using any of the methods in Sec. 98.234(a), 
emissions are detected whenever a leak is detected according to the 
methods.
    (ii) For wet seal oil degassing vents in operating-mode, determine 
vapor volumes at standard conditions, using a temporary meter such as a 
vane anemometer or permanent flow meter according to methods set forth 
in Sec. 98.234(b).
    (3) Methods for continuous measurement from individual centrifugal 
compressor sources. If you elect to conduct continuous volumetric 
emission measurements for an individual compressor source as specified 
in paragraph (o)(1)(ii) of this section, you must measure volumetric 
emissions as specified in paragraphs (o)(3)(i) and (ii) of this section.
    (i) Continuously measure the volumetric flow for the individual 
compressor source at standard conditions using a permanent meter 
according to methods set forth in Sec. 98.234(b).
    (ii) If compressor blowdown emissions are included in the metered 
emissions specified in paragraph (o)(3)(i) of this section, the 
compressor blowdown emissions may be included with the reported 
emissions for the compressor source and do not need to be calculated 
separately using the method specified in paragraph (i) of this section 
for blowdown vent stacks.
    (4) Methods for performing as found measurements from manifolded 
groups of centrifugal compressor sources. If conducting measurements for 
a manifolded group of compressor sources, you must measure volumetric 
emissions as specified in paragraphs (o)(4)(i) and (ii) of this section.
    (i) Measure at a single point in the manifold downstream of all 
compressor inputs and, if practical, prior to comingling with other non-
compressor emission sources.
    (ii) Determine the volumetric flow at standard conditions from the 
common stack using one of the methods specified in paragraphs 
(o)(4)(ii)(A) through (E) of this section.
    (A) A temporary meter such as a vane anemometer according the 
methods set forth in Sec. 98.234(b).
    (B) Calibrated bagging according to methods set forth in Sec. 
98.234(c).
    (C) A high volume sampler according to methods set forth Sec. 
98.234(d).
    (D) An acoustic leak detection device according to methods set forth 
in Sec. 98.234(a)(5).
    (E) You may choose to use any of the methods set forth in Sec. 
98.234(a) to screen for emissions. If emissions are detected using the 
methods set forth in Sec. 98.234(a), then you must use one of the 
methods specified in paragraph (o)(4)(ii)(A) through (o)(4)(ii)(D) of 
this section. If emissions are not detected using the methods in Sec. 
98.234(a), then you may assume that the volumetric emissions are zero. 
For the purposes of this paragraph, when using any of the

[[Page 858]]

methods in Sec. 98.234(a), emissions are detected whenever a leak is 
detected according to the method.
    (5) Methods for continuous measurement from manifolded groups of 
centrifugal compressor sources. If you elect to conduct continuous 
volumetric emission measurements for a manifolded group of compressor 
sources as specified in paragraph (o)(1)(iv) of this section, you must 
measure volumetric emissions as specified in paragraphs (o)(5)(i) 
through (iii) of this section.
    (i) Measure at a single point in the manifold downstream of all 
compressor inputs and, if practical, prior to comingling with other non-
compressor emission sources.
    (ii) Continuously measure the volumetric flow for the manifolded 
group of compressor sources at standard conditions using a permanent 
meter according to methods set forth in Sec. 98.234(b).
    (iii) If compressor blowdown emissions are included in the metered 
emissions specified in paragraph (o)(5)(ii) of this section, the 
compressor blowdown emissions may be included with the reported 
emissions for the manifolded group of compressor sources and do not need 
to be calculated separately using the method specified in paragraph (i) 
of this section for blowdown vent stacks.
    (6) Method for calculating volumetric GHG emissions from as found 
measurements for individual centrifugal compressor sources. For 
compressor sources measured according to paragraph (o)(1)(i) of this 
section, you must calculate annual GHG emissions from the compressor 
sources as specified in paragraphs (o)(6)(i) through (iv) of this 
section.
    (i) Using Equation W-21 of this section, calculate the annual 
volumetric GHG emissions for each centrifugal compressor mode-source 
combination specified in paragraphs (o)(1)(i)(A) and (B) of this section 
that was measured during the reporting year.

section and report emissions from the flare as specified in Sec. 
98.236(n), without subtracting emissions attributable to compressor 
sources from the flare.
    (iii) Report all applicable activity data for compressors with

must calculate and report emissions as specified in subpart C of this 
part. If emissions from a compressor source are routed to vapor 
recovery, paragraphs (p)(1) through (12) do not apply. If you are 
required to report emissions from reciprocating compressor venting at an 
onshore petroleum and natural gas production facility as specified in 
Sec. 98.232(c)(11) or an onshore petroleum and natural gas gathering 
and boosting facility as specified in Sec. 98.232(j)(5), you must 
calculate volumetric emissions as specified in paragraph (p)(10); and 
calculate CH4 and CO2 mass emissions as specified 
in paragraph (p)(11).
    (1) General requirements for conducting volumetric emission 
measurements. You must conduct volumetric emission measurements on each 
reciprocating compressor as specified in this paragraph. Compressor 
sources (as defined in Sec. 98.238) without manifolded vents must use a 
measurement method specified in paragraph (p)(1)(i) or (ii) of this 
section. Manifolded compressor sources (as defined in Sec. 98.238) must 
use a measurement method specified in paragraph (p)(1)(i), (ii), (iii), 
or (iv) of this section.
    (i) Reciprocating compressor source as found measurements. Measure 
venting from each compressor according to either paragraph (p)(1)(i)(A), 
(B), or (C) of this section at least once annually, based on the 
compressor mode (as defined in Sec. 98.238) in which the compressor was 
found at the time of measurement, except as specified in paragraphs 
(p)(1)(i)(D) and (E) of this section. If additional measurements beyond 
the required annual testing are

[[Page 862]]

performed (including duplicate measurements or measurement of additional 
operating modes), then all measurements satisfying the applicable 
monitoring and QA/QC that is required by this paragraph (o) must be used 
in the calculations specified in this section.
    (A) For a compressor measured in operating-mode, you must measure 
volumetric emissions from blowdown valve leakage through the blowdown 
vent as specified in either paragraph (p)(2)(i)(A) or (B) of this 
section, and measure volumetric emissions from reciprocating rod packing 
as specified in paragraph (p)(2)(ii) of this section.
    (B) For a compressor measured in standby-pressurized-mode, you must 
measure volumetric emissions from blowdown valve leakage through the 
blowdown vent as specified in either paragraph (p)(2)(i)(A) or (B) of 
this section.
    (C) For a compressor measured in not-operating-depressurized-mode, 
you must measure volumetric emissions from isolation valve leakage as 
specified in either paragraph (p)(2)(i)(A), (B), or (C) of this section. 
If a compressor is not operated and has blind flanges in place 
throughout the reporting period, measurement is not required in this 
compressor mode.
    (D) You must measure the compressor as specified in paragraph 
(p)(1)(i)(C) of this section at least once in any three consecutive 
calendar years, provided the measurement can be taken during a scheduled 
shutdown. If there is no scheduled shutdown within three consecutive 
calendar years, you must measure the compressor as specified in 
paragraph (p)(1)(i)(C) of this section at the next scheduled 
depressurized shutdown. For purposes of this paragraph, a scheduled 
shutdown means a shutdown that requires a compressor to be taken off-
line for planned or scheduled maintenance. A scheduled shutdown does not 
include instances when a compressor is taken offline due to a decrease 
in demand but must remain available.
    (E) An annual as found measurement is not required in the first year 
of operation for any new compressor that begins operation after as found 
measurements have been conducted for all existing compressors. For only 
the first year of operation of new compressors, calculate emissions 
according to paragraph (p)(6)(ii) of this section.
    (ii) Reciprocating compressor source continuous monitoring. Instead 
of measuring the compressor source according to paragraph (p)(1)(i) of 
this section for a given compressor, you may elect to continuously 
measure volumetric emissions from a compressor source as specified in 
paragraph (p)(3) of this section.
    (iii) Manifolded reciprocating compressor source as found 
measurements. For a compressor source that is part of a manifolded group

this section, you may elect to measure combined volumetric emissions 
from the manifolded group of compressor sources by conducting 
measurements at the common vent stack as specified in paragraph (p)(4) 
of this section. The measurements must be conducted at the frequency 
specified in paragraphs (p)(1)(iii)(A) and (B) of this section.

          as leaking in any leak survey during the year. A component 
          found leaking in two or more surveys during the year is 
          counted as one leaking component.
EFs,p = Leaker emission factor for specific component types 
          listed in Tables W-1E, W-2, W-3A, W-4A, W-5A, W-6A, and W-7 to 
          this subpart.
GHGi = For onshore petroleum and natural gas production 
          facilities and onshore petroleum and natural gas gathering and 
          boosting facilities, concentration of GHGi, 
          CH4, or CO2, in produced natural gas as 
          defined in paragraph (u)(2) of this section; for onshore 
          natural gas processing facilities, concentration of 
          GHGi, CH4 or CO2, in the 
          total hydrocarbon of the feed natural gas; for onshore natural 
          gas transmission compression and underground natural gas 
          storage, GHGi equals 0.975 for CH4 and 
          1.1 x 10-2 for CO2; for LNG storage and

          type ``p,'' was assumed to be leaking and operational, in 
          hours. If one leak detection survey is conducted in the 
          calendar year, assume the component was leaking for the entire 
          calendar year. If multiple leak detection surveys are 
          conducted in the calendar year, assume a component found 
          leaking in the first survey was leaking since the beginning of 
          the year until the date of the survey; assume a component 
          found leaking in the last survey of the year was leaking from 
          the preceding survey through the end of the year; assume a 
          component found leaking in a survey between the first and last 
          surveys of the year was leaking since the preceding survey 
          until the date of the survey; and sum times for all leaking 
          periods. For each leaking component, account for time the 
          component was not operational (i.e., not operating under 
          pressure) using an engineering estimate based on best 
          available data.

    (i) You must conduct at least one leak detection survey in a 
calendar year. The leak detection surveys selected must be conducted 
during the calendar year. If you conduct multiple complete leak 
detection surveys in a calendar year, you must use the results from each 
complete leak detection survey when calculating emissions using Equation 
W-30. For components subject to the well site and compressor station 
fugitive emissions standards in Sec. 60.5397a of this chapter, each 
survey conducted in accordance with Sec. 60.5397a of this chapter will 
be considered a complete leak detection survey for purposes of this 
section.
    (ii) Calculate both CO2 and CH4 mass emissions 
using calculations in paragraph (v) of this section.
    (iii) Onshore petroleum and natural gas production facilities must 
use the appropriate default whole gas leaker emission factors for 
components in gas service, light crude service, and heavy crude service 
listed in Table W-1E to this subpart.
    (iv) Onshore petroleum and natural gas gathering and boosting 
facilities must use the appropriate default whole gas leaker factors for 
components in gas service listed in Table W-1E to this subpart.
    (v) Onshore natural gas processing facilities must use the 
appropriate default total hydrocarbon leaker emission factors for 
compressor components in gas service and non-compressor components in

for compressor components in gas service and non-compressor components 
in gas service listed in Table W-3A to this subpart.
    (vii) Underground natural gas storage facilities must use the 
appropriate default total hydrocarbon leaker emission factors for 
storage stations or storage wellheads in gas service listed in Table W-
4A to this subpart.

[[Page 870]]

    (viii) LNG storage facilities must use the appropriate default 
methane leaker emission factors for LNG storage components in LNG 
service or gas service listed in Table W-5A to this subpart.
    (ix) LNG import and export facilities must use the appropriate 
default methane leaker emission factors for LNG terminals components in 
LNG service or gas service listed in Table W-6A to this subpart.
    (x) Natural gas distribution facilities must use Equation W-30 of 
this section and the default methane leaker emission factors for 
transmission-distribution transfer station components in gas service 
listed in Table W-7 to this subpart to calculate component emissions 
from annual equipment leak surveys conducted at above grade 
transmission-distribution transfer stations. Natural gas distribution 
facilities are required to perform equipment leak surveys only at above 
grade stations that qualify as transmission-distribution transfer 
stations. Below grade transmission-distribution transfer stations and 
all metering-regulating stations that do not meet the definition of 
transmission-distribution transfer stations are not required to perform 
equipment leak surveys under this section.
    (A) Natural gas distribution facilities may choose to conduct 
equipment leak surveys at all above grade transmission-distribution 
transfer stations over multiple years ``n,'' not exceeding a five year 
period to cover all above grade transmission-distribution transfer 
stations. If the facility chooses to use the multiple year option, then 
the number of transmission-distribution transfer stations that are 
monitored in each year should be approximately equal across all years in 
the cycle.
    (B) Use Equation W-31 of this section to determine the meter/
regulator run population emission factors for each GHGi. As 
additional survey data become available, you must recalculate the meter/
regulator run population emission factors for each GHGi 
annually according to paragraph (q)(2)(x)(C) of this section.

Where:

EFs,MR,i = Meter/regulator run population emission factor for 
          GHGi based on all surveyed above grade 
          transmission-distribution transfer stations over ``n'' years, 
          in standard cubic feet of GHGi per operational hour 
          of all meter/regulator runs.

          conditions of GHGi from component type ``p'' during

          was operational, in hours during survey year ``y'' using an 
          engineering estimate based on best available data.

          grade transmission-distribution transfer stations in year

          section, whose results are used to calculate emission factor 
          ``EFs,MR,i'' according to paragraph (q)(2)(x)(C) of 
          this section.

    (C) The emission factor ``EFs,MR,i,'' based on annual 
equipment leak surveys at above grade transmission-distribution transfer 
stations, must be calculated annually. If you chose to conduct equipment 
leak surveys at all above grade transmission-distribution transfer 
stations over multiple years,

[[Page 871]]

``n,'' according to paragraph (q)(2)(x)(A) of this section and you have 
submitted a smaller number of annual reports than the duration of the 
selected cycle period of 5 years or less, then all available data from 
the current year and previous years must be used in the calculation of 
the emission factor ``EFs,MR,i'' from Equation W-31 of this 
section. After the first survey cycle of ``n'' years is completed and 
beginning in calendar year (n+1), the survey will continue on a rolling 
basis by including the survey results from the current calendar year 
``y'' and survey results from all previous (n-1) calendar years, such 
that each annual calculation of the emission factor 
``EFs,MR,i'' from Equation W-31 is based on survey results 
from ``n'' years. Upon completion of a cycle, you may elect to change 
the number of years in the next cycle period (to be 5 years or less). If 
the number of years in the new cycle is greater than the number of years 
in the previous cycle, calculate ``EFs,MR,i'' from Equation 
W-31 in each year of the new cycle using the survey results from the 
current calendar year and the survey results from the preceding number 
years that is equal to the number of years in the previous cycle period. 
If the number of years, ``nnew,'' in the new cycle is smaller 
than the number of years in the previous cycle, ``n,'' calculate 
``EFs,MR,i'' from Equation W-31 in each year of the new cycle 
using the survey results from the current calendar year and survey 
results from all previous (nnew-1) calendar years.
    (xi) If you chose to conduct equipment leak surveys at all above 
grade transmission-distribution transfer stations over multiple years, 
``n,'' according to paragraph (q)(2)(x)(A) of this section, you must use 
the meter/regulator run population emission factors calculated using 
Equation W-31 of this section and the total count of all meter/regulator 
runs at above grade transmission-distribution transfer stations to 
calculate emissions from all above grade transmission-distribution 
transfer stations using Equation W-32B in paragraph (r) of this section.
    (r) Equipment leaks by population count. This paragraph (r) applies 
to emissions sources listed in Sec. 98.232(c)(21), (f)(7), (g)(5), 
(h)(6), and (j)(10) if you are not required to comply with paragraph (q) 
of this section and if you do not elect to comply with paragraph (q) of 
this section for these components in lieu of this paragraph (r). This 
paragraph (r) also applies to emission sources listed in Sec. 
98.232(i)(2), (i)(3), (i)(4), (i)(5), (i)(6), and (j)(11). To be subject 
to the requirements of this paragraph (r), the listed emissions sources 
also must contact streams with gas content greater than 10 percent 
CH plus CO2 by weight. Emissions sources that 
contact streams with gas content less than or equal to 10 percent 
CH4 plus CO2 by weight are exempt from the 
requirements of this paragraph (r) and do not need to be reported. 
Tubing systems equal to or less than one half inch diameter are exempt 
from the requirements of paragraph (r) of this section and do not need 
to be reported. You must calculate emissions from all emission sources 
listed in this paragraph using Equation W-32A of this section, except 
for natural gas distribution facility emission sources listed in Sec. 
98.232(i)(3). Natural gas distribution facility emission sources listed 
in Sec. 98.232(i)(3) must calculate emissions using Equation W-32B of 
this section and according to paragraph (r)(6)(ii) of this section.

Where:

Es,n = Natural gas volumetric emissions at standard 
          temperature and pressure (STP) conditions in cubic feet,

          when calculating either subsonic or sonic flowrates under 
          Sec. 98.233(g).
Ea,n = Natural gas volumetric emissions at actual conditions 
          in cubic feet, except Ea,n equals FRa,p 
          for each well p when calculating either subsonic or sonic 
          flowrates under Sec. 98.233(g).
Ts = Temperature at standard conditions (60 [deg]F).

Ps = Absolute pressure at standard conditions (14.7 psia).
Pa = Absolute pressure at actual conditions (psia).

          gas. You may use either a default compressibility factor of 1, 
          or a site-specific compressibility factor based on actual 
          temperature and pressure conditions.

    (2) Calculate GHG volumetric emissions at standard conditions using 
actual GHG emissions temperature and pressure, and Equation W-34 of this 
section.

Ta = Temperature at actual emission conditions ( [deg]F).
Ps = Absolute pressure at standard conditions (14.7 psia).
Pa = Absolute pressure at actual conditions (psia).
Za = Compressibility factor at actual conditions for GHG i.

    You may use either a default compressibility factor of 1, or a site-

(vii) of this section.
    (i) GHG mole fraction in produced natural gas for onshore petroleum 
and natural gas production facilities and onshore petroleum and natural 
gas gathering and boosting facilities. If you have a continuous gas 
composition analyzer for produced natural gas, you must use an annual 
average of these values for determining the mole fraction. If you do not

upstream of the de-methanizer or dew point control and GHG mole fraction

all emissions sources downstream of the de-methanizer overhead or dew 
point control for onshore natural gas processing facilities. For onshore 
natural gas processing plants that solely fractionate a liquid stream, 
use the GHG mole percent in feed natural gas liquid for all streams. If 
you have a continuous gas composition analyzer on feed natural gas, you 
must use these values for determining the mole fraction. If you do not 
have a continuous gas composition analyzer, then annual samples must be 
taken according to methods set forth in Sec. 98.234(b).

passes through the facility for the onshore natural gas transmission 
compression industry segment and the onshore natural gas transmission

the monitoring and QA/QC requirements as set forth in 30 CFR 250.
    (a) You must use any of the methods described in paragraphs (a)(1) 
through (5) of this section to conduct leak detection(s) of through-
valve leakage from all source types listed in Sec. 98.233(k), (o), and 
(p) that occur during a calendar year. You must use any of the methods 
described in paragraphs (a)(1) through (7) of this section to conduct 
leak detection(s) of equipment leaks from components as specified in 
Sec. 98.233(q)(1)(i) that occur during a calendar year. You must use 
any of the methods described in paragraphs (a)(1) through (5) of this 
section to conduct leak detection(s) of equipment leaks from components 
as specified in Sec. 98.233(q)(1)(ii) that occur during a calendar 
year. You must use one of the methods described in paragraph (a)(6) or 
(7) of this section to conduct leak detection(s) of equipment leaks from 
components as specified in Sec. 98.233(q)(1)(iii). If electing to 
comply with Sec. 98.233(q) as specified in Sec. 98.233(q)(1)(iv), you 
must use any of the methods described in paragraphs (a)(1) through (7) 
of this section to conduct leak detection(s) of equipment leaks from 
component types as specified in Sec. 98.233(q)(1)(iv) that occur during 
a calendar year.
    (1) Optical gas imaging instrument as specified in Sec. 60.18 of 
this chapter. Use an optical gas imaging instrument for equipment leak 
detection in accordance with 40 CFR part 60, subpart A, Sec. 60.18 of 
the Alternative work practice for monitoring equipment leaks, Sec. 
60.18(i)(1)(i); Sec. 60.18(i)(2)(i) except that the monitoring 
frequency shall be annual using the detection sensitivity level of 60 
grams per hour as stated in 40 CFR Part 60, subpart A, Table 1: 
Detection Sensitivity Levels; Sec. 60.18(i)(2)(ii) and (iii) except the 
gas chosen shall be methane, and Sec. 60.18(i)(2)(iv) and (v); Sec. 
60.18(i)(3); Sec. 60.18(i)(4)(i) and (v); including the requirements 
for daily instrument checks and distances, and excluding requirements 
for video records. Any emissions detected by the optical gas imaging 
instrument is a leak unless screened with Method 21 (40 CFR part 60, 
appendix A-7) monitoring, in which case 10,000 ppm or greater is 
designated a leak. In addition, you must operate the optical gas imaging 
instrument to image the source types required by this subpart in 
accordance with the instrument manufacturer's operating parameters. 
Unless using methods in paragraph (a)(2) of this section, an optical gas 
imaging instrument must be used for all source types that are 
inaccessible and cannot be monitored without elevating the monitoring 
personnel more than 2 meters above a support surface.
    (2) Method 21. Use the equipment leak detection methods in 40 CFR 
part 60, appendix A-7, Method 21. If using Method 21 monitoring, if an 
instrument reading of 10,000 ppm or greater is measured, a leak is 
detected. Inaccessible emissions sources, as defined in 40 CFR part 60, 
are not exempt from this subpart. If the equipment leak detection 
methods in this paragraph cannot be used, you must use alternative leak 
detection devices as described in paragraph (a)(1) of this section to 
monitor inaccessible equipment leaks or vented emissions.
    (3) Infrared laser beam illuminated instrument. Use an infrared 
laser beam illuminated instrument for equipment leak detection. Any 
emissions detected by the infrared laser beam illuminated instrument is

ppm or greater is designated a leak. In addition, you must operate the 
infrared laser beam illuminated instrument to detect the source types 
required by this subpart in accordance with the instrument 
manufacturer's operating parameters.

device to detect through-valve leakage. When using the acoustic leak 
detection device to quantify the through-valve leakage, you must use the 
instrument manufacturer's calculation methods to quantify the through-
valve leak. When using the acoustic leak detection device, if a leak of 
3.1 scf per hour or greater is calculated, a leak is detected. In 
addition, you must operate the acoustic leak detection device to

[[Page 880]]

monitor the source valves required by this subpart in accordance with 
the instrument manufacturer's operating parameters. Acoustic stethoscope 
type devices designed to detect through valve leakage when put in 
contact with the valve body and that provide an audible leak signal but 
do not calculate a leak rate can be used to identify non-leakers with 
subsequent measurement required to calculate the rate if through-valve 
leakage is identified. Leaks are reported if a leak rate of 3.1 scf per 
hour or greater is measured.
    (6) Optical gas imaging instrument as specified in Sec. 60.5397a of 
this chapter. Use an optical gas imaging instrument for equipment leak 
detection in accordance with Sec. 60.5397a(b), (c)(3), (c)(7), and (e) 
of this chapter and paragraphs (a)(6)(i) through (iii) of this section.

imaging instrument must be used for all source types that are 
inaccessible and cannot be monitored without elevating the monitoring 
personnel more than 2 meters above a support surface.
    (i) For the purposes of this subpart, any visible emissions from a 
component listed in Sec. 98.232 observed by the optical gas imaging 
instrument is a leak.
    (ii) For the purposes of this subpart, the term ``fugitive emissions 
component'' in Sec. 60.5397a of this chapter means ``component.''
    (iii) For the purpose of complying with Sec. 98.233(q)(1)(iv), the 
phrase ``the collection of fugitive emissions components at well sites 
and compressor stations'' in Sec. 60.5397a(b) of this chapter means 
``the collection of components for which you elect to comply with Sec. 
98.233(q)(1)(iv).''
    (7) Method 21 as specified in Sec. 60.5397a of this chapter. Use 
the equipment leak detection methods in appendix A-7 to part 60 of this 
chapter, Method 21, in accordance with Sec. 60.5397a(b), (c)(8), and 
(e) of this chapter and paragraphs (a)(7)(i) through (iii) of this 
section. Inaccessible emissions sources, as defined in part 60 of this 
chapter, are not exempt from this subpart. If the equipment leak 
detection methods in this paragraph cannot be used, you must use 
alternative leak detection devices as described in paragraph (a)(6) of 
this section to monitor inaccessible equipment leaks.
    (i) For the purposes of this subpart, any instrument reading from a 
component listed in Sec. 98.232 of this chapter of 500 ppm or greater 
using Method 21 is a leak.
    (ii) For the purposes of this subpart, the term ``fugitive emissions 
component'' in Sec. 60.5397a of this chapter means ``component.''
    (iii) For the purpose of complying with Sec. 98.233(q)(1)(iv), the 
phrase ``the collection of fugitive emissions components at well sites 
and compressor stations'' in Sec. 60.5397a(b) of this chapter means 
``the collection of components for which you elect to comply with Sec. 
98.233(q)(1)(iv).''
    (b) You must operate and calibrate all flow meters, composition 
analyzers and pressure gauges used to measure quantities reported in 
Sec. 98.233 according to the procedures in Sec. 98.3(i) and the 
procedures in paragraph (b) of this section. You may use an appropriate 
standard method published by a consensus-based standards organization if 
such a method exists or you may use an industry standard practice. 
Consensus-based standards organizations include, but are not limited to, 
the following: ASTM International, the American National Standards 
Institute (ANSI), the American Gas Association (AGA), the American 
Society of Mechanical Engineers (ASME), the American Petroleum Institute 
(API), and the North American Energy Standards Board (NAESB).
    (c) Use calibrated bags (also known as vent bags) only where the 
emissions are at near-atmospheric pressures and below the maximum 
temperature specified by the vent bag manufacturer such that the bag is 
safe to handle. The bag opening must be of sufficient size that the 
entire emission can be tightly encompassed for measurement till the bag 
is completely filled.
    (1) Hold the bag in place enclosing the emissions source to capture 
the entire emissions and record the time required for completely filling 
the bag. If the bag inflates in less than one second, assume one second 
inflation time.

report

[[Page 881]]

the emissions as the average of the three readings.
    (3) Estimate natural gas volumetric emissions at standard conditions 
using calculations in Sec. 98.233(t).
    (4) Estimate CH4 and CO2 volumetric and mass 
emissions from volumetric natural gas emissions using the calculations 
in Sec. 98.233(u) and (v).
    (d) Use a high volume sampler to measure emissions within the 
capacity of the instrument.
    (1) A technician following manufacturer instructions shall conduct 
measurements, including equipment manufacturer operating procedures and 
measurement methods relevant to using a high volume sampler, including 
positioning the instrument for complete capture of the equipment leak 
without creating backpressure on the source.
    (2) If the high volume sampler, along with all attachments available 
from the manufacturer, is not able to capture all the emissions from the 
source then use anti-static wraps or other aids to capture all emissions 
without violating operating requirements as provided in the instrument 
manufacturer's manual.
    (3) Estimate natural gas volumetric emissions at standard conditions 
using calculations in Sec. 98.233(t). Estimate CH4 and 
CO2 volumetric and mass emissions from volumetric natural gas 
emissions using the calculations in Sec. 98.233(u) and (v).
    (4) Calibrate the instrument at 2.5 percent methane with 97.5 
percent air and 100 percent CH4 by using calibrated gas 
samples and by following manufacturer's instructions for calibration.

Sec. 98.235  Procedures for estimating missing data.

    Except as specified in Sec. 98.233, whenever a value of a parameter 
is unavailable for a GHG emission calculation required by this subpart 
(including, but not limited to, if a measuring device malfunctions 
during unit operation or activity data are not collected), you must 
follow the procedures specified in paragraphs (a) through (i) of this 
section, as applicable.
    (a) For stationary and portable combustion sources that use the 
calculation methods of subpart C of this part, you must use the missing 
data procedures in subpart C of this part.
    (b) For each missing value of a parameter that should have been 
measured quarterly or more frequently using equipment including, but not 
limited to, a continuous flow meter, composition analyzer, thermocouple, 
or pressure gauge, you must substitute the arithmetic average of the 
quality-assured values of that parameter immediately preceding and 
immediately following the missing data incident. If the ``after'' value 
is not obtained by the end of the reporting year, you may use the 
``before'' value for the missing data substitution. If, for a particular 
parameter, no quality-assured data are available prior to the missing 
data incident, you must use the first quality-assured value obtained 
after the missing data period as the substitute data value. A value is 
quality-assured according to the procedures specified in Sec. 98.234.
    (c) For each missing value of a parameter that should have been 
measured annually, you must repeat the estimation or measurement 
activity for those sources as soon as possible, including in the 
subsequent calendar year if missing data are not discovered until after 
December 31 of the year in which data are collected, until valid data 
for reporting are obtained. Data developed and/or collected in a 
subsequent calendar year to substitute for missing data cannot be used 
for that subsequent year's emissions estimation. Where missing data 
procedures are used for the previous year, at least 30 days must 
separate emissions estimation or measurements for the previous year and 
emissions estimation or measurements for the current year of data 
collection.
    (d) For each missing value of a parameter that should have been 
measured biannually (every two years), you must conduct the estimation 
or measurement activity for those sources as soon as possible in the 
subsequent calendar year if the estimation or measurement was not made 
in the appropriate year (first year of data collection and every two 
years thereafter), until valid data for reporting are obtained. Data 
developed and/or collected in a subsequent calendar year to substitute 
for missing data cannot be used to alternate or postpone subsequent 
biannual emissions estimations or measurements.
    (e) For the first 6 months of required data collection, facilities 
that become newly subject to this subpart W may use best engineering 
estimates for any data that cannot reasonably be measured or obtained 
according to the requirements of this subpart.
    (f) For the first 6 months of required data collection, facilities 
that are currently subject to this subpart W and that acquire new 
sources from another facility that were not previously subject to this 
subpart W may use best engineering estimates for any data related to 
those newly acquired sources that cannot reasonably be measured or 
obtained according to the requirements of this subpart.
    (g) Unless addressed in another paragraph of this section, for each 
missing value of any activity data, you must substitute data value(s) 
using the best available estimate(s) of the parameter(s), based on all 
applicable and available process or other data (including, but not 
limited to, processing rates, operating hours).
    (h) You must report information for all measured and substitute 
values of a parameter, and the procedures used to

[[Page 885]]

substitute an unavailable value of a parameter per the requirements in 
Sec. 98.236(bb).
    (i) You must follow recordkeeping requirements listed in Sec. 
98.237(f).

States, including waters subject to the ebb and flow of the tide, as 
well as adjacent bays, lakes or other normally standing waters, and 
extending to the outer boundaries of the jurisdiction and control of the

other tight gas reservoir rock. The distinction between high 
permeability gas and tight gas reservoirs shall be designated as 
follows: High permeability gas reservoirs with 0.1 millidarcy 
permeability, and tight gas reservoirs with <=0.1 millidarcy 
permeability. Permeability for a reservoir type shall be determined by 
engineering estimate. Wells that produce only from high permeability 
gas, shale gas, coal seam, or other tight gas reservoir rock are 
considered gas wells; gas wells producing from more than one of these 
formation types shall be classified into only one type based on the 
formation with the most contribution to production as determined by 
engineering knowledge. All wells that produce hydrocarbon liquids (with 
or without gas) and do not meet the definition of a gas well in this 
sub-basin category definition are considered to be in the oil formation. 
All emission sources that handle condensate from gas wells in high 
permeability gas, shale gas, or tight gas reservoir rock formations are 
considered to be in the formation that the gas well belongs to and not 
in the oil formation.

some unintentional deviation or one or more intentional deviations to 
enter one or more subsurface targets that are off-set horizontally from 
the surface location, intercepting the targets either vertically or at 
an angle.

identification number assigned to a petroleum or natural gas well. If 
the well has been assigned a US Well Number, the well ID number required 
in this subpart is the US Well Number. If a US Well Number has not been

                   Subpart X_Petrochemical Production



Sec. 98.240  Definition of the source category.

    (a) The petrochemical production source category consists of 
processes as described in paragraphs (a)(1) and (2) of this section.
    (1) The petrochemical production source category consists of all 
processes that produce acrylonitrile, carbon black, ethylene, ethylene 
dichloride, ethylene oxide, or methanol, as either an intermediate in 
the on-site production of other chemicals or as an end product for sale 
or shipment off site, except as specified in paragraphs (b) through (g) 
of this section.
    (2) When ethylene dichloride and vinyl chloride monomer are produced 
in an integrated process, you may consider the entire integrated process 
to be the petrochemical process for the purpose of complying with the 
mass balance option in Sec. 98.243(c). If you elect to consider the 
integrated process to be the petrochemical process, then the mass 
balance must be performed over the entire integrated process.
    (b) A process that produces a petrochemical as a byproduct is not 
part of the petrochemical production source category.
    (c) A facility that makes methanol, hydrogen, and/or ammonia from 
synthesis gas is part of the petrochemical source category if the annual 
mass of methanol produced exceeds the individual annual mass production 
levels of both hydrogen recovered as product and ammonia. The facility 
is part of subpart P of this part (Hydrogen Production) if the annual 
mass of hydrogen recovered as product exceeds the individual annual mass 
production levels of both methanol and ammonia. The facility is part of 
subpart G of this part (Ammonia Manufacturing) if the annual mass of 
ammonia produced exceeds the individual annual mass production levels of 
both hydrogen recovered as product and methanol.
    (d) A direct chlorination process that is operated independently of 
an oxychlorination process to produce ethylene dichloride is not part of 
the petrochemical production source category.
    (e) A process that produces bone black is not part of the 
petrochemical source category.
    (f) A process that produces a petrochemical from bio-based feedstock 
is

[[Page 925]]

not part of the petrochemical production source category.
    (g) A process that solely distills or recycles waste solvent that 
contains a petrochemical is not part of the petrochemical production 
source category.

76 FR 80590, Dec. 23, 2011; 81 FR 89260, Dec. 9, 2016]



Sec. 98.241  Reporting threshold.

    You must report GHG emissions under this subpart if your facility 
contains a petrochemical process as specified in Sec. 98.240, and the 
facility meets the requirements of either Sec. 98.2(a)(1) or (2).



Sec. 98.242  GHGs to report.

    You must report the information in paragraphs (a) through (c) of 
this section:
    (a) CO2 CH4, and N2O process 
emissions from each petrochemical process unit. Process emissions 
include CO2 generated by reaction in the process and by 
combustion of process off-gas in stationary combustion units and flares.
    (1) If you comply with Sec. 98.243(b) or (d), report under this 
subpart the calculated CO2, CH4, and 
N2O emissions for each stationary combustion source and flare 
that burns any amount of petrochemical process off-gas. If you comply 
with Sec. 98.243(b), also report under this subpart the measured 
CO2 emissions from process vents routed to stacks that are 
not associated with stationary combustion units.
    (2) If you comply with Sec. 98.243(c), report under this subpart 
the calculated CO2 emissions for each petrochemical process 
unit.
    (b) CO2, CH4, and N2O combustion 
emissions from stationary combustion units.
    (1) If you comply with Sec. 98.243(b) or (d), report these 
emissions from stationary combustion units that are associated with 
petrochemical process units and burn only supplemental fuel under 
subpart C of this part (General Stationary Fuel Combustion Sources) by 
following the requirements of subpart C.
    (2) If you comply with Sec. 98.243(c), report CO2, 
CH4, and N2O combustion emissions under subpart C 
of this part (General Stationary Fuel Combustion Sources) by following 
the requirements of subpart C for all fuels, except emissions from 
burning petrochemical process off-gas in any combustion unit, including 
units that are not part of the petrochemical process unit, are not to be 
reported under subpart C of this part. Determine the applicable Tier in 
subpart C of this part (General Stationary Fuel Combustion Sources) 
based on the maximum rated heat input capacity of the stationary 
combustion source.
    (c) CO2 captured. You must report the mass of 
CO2 captured under, subpart PP of this part (Suppliers of 
Carbon Dioxide (CO2) by following the requirements of subpart 
PP.

[74 FR 56374, Oct. 30, 2009, as amended at 75 FR 79157, Dec. 17, 2010; 
78 FR 71960, Nov. 29, 2013]



Sec. 98.243  Calculating GHG emissions.

    (a) If you route all process vent emissions and emissions from 
combustion of process off-gas to one or more stacks and use CEMS on each 
stack to measure CO2 emissions (except flare stacks), then 
you must determine process-based GHG emissions in accordance with 
paragraph (b) of this section. Otherwise, determine process-based GHG 
emissions in accordance with the procedures specified in paragraph (c) 
or (d) of this section.
    (b) Continuous emission monitoring system (CEMS). Route all process 
vent emissions and emissions from stationary combustion units that burn 
any amount of process off-gas to one or more stacks and determine GHG 
emissions as specified in paragraphs (b)(1) through (3) of this section.
    (1) Determine CO2 emissions from each stack (except flare 
stacks) according to the Tier 4 Calculation Methodology requirements in 
subpart C of this part.
    (2) For each stack (except flare stacks) that includes emissions 
from combustion of petrochemical process off-gas, calculate 
CH4 and N2O emissions in accordance with subpart C 
of this part (use Equation C-10 and the ``fuel gas'' emission factors in 
Table C-2 of subpart C of this part).

[[Page 926]]

    (3) For each flare, calculate CO2, CH4, and 
N2O emissions using the methodology specified in Sec. 
98.253(b)(1) through (3).
    (c) Mass balance for each petrochemical process unit. Calculate the 
emissions of CO2 from each process unit, for each calendar 
month as described in paragraphs (c)(1) through (c)(5) of this section.
    (1) For each gaseous and liquid feedstock and product, measure the 
volume or mass used or produced each calendar month with a flow meter by 
following the procedures specified in Sec. 98.244(b)(2). Alternatively, 
for liquids, you may calculate the volume used or collected in each 
month based on measurements of the liquid level in a storage tank at 
least once per month (and just prior to each change in direction of the 
level of the liquid) following the procedures specified in Sec. 
98.244(b)(3). Fuels used for combustion purposes are not considered to 
be feedstocks.
    (2) For each solid feedstock and product, measure the mass used or 
produced each calendar month by following the procedures specified in 
Sec. 98.244(b)(1).
    (3) Collect a sample of each feedstock and product at least once per 
month and determine the molecular weight (for gaseous materials when the 
quantity is measured in scf) and carbon content of each sample according 
to the procedures of Sec. 98.244(b)(4). If multiple valid molecular 
weight or carbon content measurements are made during the monthly 
measurement period, average them arithmetically. However, if a 
particular liquid or solid feedstock is delivered in lots, and if 
multiple deliveries of the same feedstock are received from the same 
supply source in a given calendar month, only one representative sample 
is required. Alternatively, you may use the results of analyses 
conducted by a feedstock supplier, or product customer, provided the 
sampling and analysis is conducted at least once per month using any of 
the procedures specified in Sec. 98.244(b)(4).
    (4) If you determine that the monthly average concentration of a 
specific compound in a feedstock or product is greater than 99.5 percent 
by volume or mass, then as an alternative to the sampling and analysis 
specified in paragraph (c)(3) of this section, you may determine 
molecular weight and carbon content in accordance with paragraphs 
(c)(4)(i) through (iii) of this section.
    (i) Calculate the molecular weight and carbon content assuming 100 
percent of that feedstock or product is the specific compound.
    (ii) Maintain records of any determination made in accordance with 
this paragraph (c)(4) along with all supporting data, calculations, and 
other information.
    (iii) Reevaluate determinations made under this paragraph (c)(4) 
after any process change that affects the feedstock or product 
composition. Keep records of the process change and the corresponding 
composition determinations. If the feedstock or product composition 
changes so that the average monthly concentration falls below 99.5 
percent, you are no longer permitted to use this alternative method.
    (5) Calculate the CO2 mass emissions for each 
petrochemical process unit using Equations X-1 through X-4 of this 
section.
    (i) Gaseous feedstocks and products. Use Equation X-1 of this 
section to calculate the net annual carbon input or output from gaseous 
feedstocks and products. Note that the result will be a negative value 
if there are no gaseous feedstocks in the process but there are gaseous 
products.

                     Subpart Y_Petroleum Refineries



Sec. 98.250  Definition of source category.

    (a) A petroleum refinery is any facility engaged in producing 
gasoline, gasoline blending stocks, naphtha, kerosene, distillate fuel 
oils, residual fuel oils, lubricants, or asphalt (bitumen) through 
distillation of petroleum or through redistillation, cracking, or 
reforming of unfinished petroleum derivatives, except as provided in 
paragraph (b) of this section.
    (b) For the purposes of this subpart, facilities that distill only 
pipeline transmix (off-spec material created when different 
specification products mix during pipeline transportation) are not 
petroleum refineries, regardless of the products produced.
    (c) This source category consists of the following sources at 
petroleum refineries: Catalytic cracking units; fluid coking units; 
delayed coking units; catalytic reforming units; coke calcining units; 
asphalt blowing operations; blowdown systems; storage tanks; process 
equipment components (compressors, pumps, valves, pressure relief 
devices, flanges, and connectors) in gas service; marine vessel, barge, 
tanker truck, and similar loading operations; flares; sulfur recovery 
plants; and non-merchant hydrogen plants (i.e., hydrogen plants that are 
owned or under the direct control of the refinery owner and operator).

methodology that was used for calculating CO2 emissions. (Use 
the default CH4 and N2O emission factors for 
``Fuel Gas'' in Table C-2 of this part. For Tier 3, use either the 
default high heat value for fuel gas in Table C-1 of subpart C of this 
part or a calculated HHV, as allowed in Equation C-8 of subpart C of 
this part.) You may aggregate units, monitor common stacks, or monitor 
common (fuel) pipes as provided in Sec. 98.36(c) when calculating and

Sec. 98.253  Calculating GHG emissions.

    (a) Calculate GHG emissions required to be reported in Sec. 
98.252(b) through (i) using the applicable methods in paragraphs (b) 
through (n) of this section.
    (b) For flares, calculate GHG emissions according to the

applicable requirements

[[Page 936]]

in paragraphs (b)(1)(i) through (b)(1)(iii) of this section.
    (i) Flow measurement. If you have a continuous flow monitor on the 
flare, you must use the measured flow rates when the monitor is 
operational and the flow rate is within the calibrated range of the 
measurement device to calculate the flare gas flow. If you do not have a 
continuous flow monitor on the flare and for periods when the monitor is 
not operational or the flow rate is outside the calibrated range of the 
measurement device, you must use engineering calculations, company 
records, or similar estimates of volumetric flare gas flow.
    (ii) Heat value or carbon content measurement. If you have a 
continuous higher heating value monitor or gas composition monitor on 
the flare or if you monitor these parameters at least weekly, you must 
use the measured heat value or carbon content value in calculating the 
CO2 emissions from the flare using the applicable methods in 
paragraphs (b)(1)(ii)(A) and (b)(1)(ii)(B).
    (A) If you monitor gas composition, calculate the CO2 
emissions from the flare using either Equation Y-1a or Equation Y-1b of 
this section. If daily or more frequent measurement data are available, 
you must use daily values when using Equation Y-1a or Equation Y-1b of 
this section; otherwise, use weekly values.

          molar volume conversion factor [849.5 scf/kg-mole at 68 [deg]F 
          and 14.7 psia or 836.6 scf/kg-mole at 60 [deg]F and 14.7 psia

(HHV)p = Higher heating value for the flare gas combusted 
          during measurement period (British thermal units per scf, Btu/

the flare separately for periods of routine flare operation and for 
periods of start-up, shutdown, or malfunction, and calculate the 
CO2 emissions as specified in paragraphs (b)(1)(iii)(A) 
through (b)(1)(iii)(C) of this section.

engineering calculations and process knowledge to estimate the carbon 
content of the flared gas for each start-up, shutdown, or malfunction 
event exceeding 500,000 scf/day.
    (B) For periods of normal operation, use the average higher heating 
value measured for the fuel gas used as flare sweep or purge gas for the 
higher heating value of the flare gas. If higher heating value of the 
fuel gas is not measured, the higher heating value of the flare gas 
under normal operations

of this section regardless of the concentration of CO2 in the 
vented gas stream. Combustion emissions from the sulfur recovery plant 
(e.g., from fuel combustion in the Claus burner or the tail gas 
treatment incinerator) must be reported under subpart C of this part 
(General Stationary Fuel Combustion Sources). For the purposes of this 
subpart, the sour gas stream for which monitoring is required according

capable of measuring carbon content on the sour gas feed to the sulfur 
recovery plant or the sour gas feed sent for off-site for sulfur

    (5) If tail gas is recycled to the front of the sulfur recovery 
plant and the recycled flow rate and carbon content is included in the 
measured data under paragraphs (f)(2) and (f)(3) of this section, 
respectively, then the annual CO2 emissions calculated in 
paragraph (f)(4) of this section must be corrected to avoid double 
counting these emissions. You may use engineering estimates to perform 
this correction or assume that the corrected CO2 emissions 
are 95 percent of the uncorrected value calculated using Equation Y-12 
of this section.
    (g) For coke calcining units, calculate GHG emissions according to 
the applicable provisions in paragraphs (g)(1) through (g)(3) of this

report CO2 emissions under this subpart by following the Tier 
4 Calculation Methodology specified in Sec. 98.33(a)(4) and all 
associated requirements for Tier 4 in subpart C of this part (General 
Stationary Fuel Combustion Sources). You must monitor fuel use in the 
coke calcining unit that discharges via the final exhaust stack from the 
coke calcining unit and calculate the combustion emissions from the fuel 
use according to subpart C of this part. Calculate the process emissions 
from the coke calcining unit as the difference in the CO2 
CEMS emissions and the calculated combustion emissions associated with 
the coke calcining unit final exhaust stack. Other coke calcining units 
must either install a CEMS that complies

follow the requirements of paragraph (g)(2) of this section.

Sec. 98.255  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required (e.g., concentrations, flow rates, 
fuel heating values, carbon content values). Therefore, whenever a 
quality-assured value of a required parameter is unavailable (e.g., if a 
CEMS malfunctions during unit operation or if a required fuel sample is 
not taken), a substitute data value for the missing parameter shall be 
used in the calculations.
    (a) For stationary combustion sources, use the missing data 
procedures in subpart C of this part.
    (b) For each missing value of the heat content, carbon content, or 
molecular weight of the fuel, substitute the arithmetic average of the 
quality-assured values of that parameter immediately preceding and 
immediately following the missing data incident. If the ``after'' value 
is not obtained by the end of the reporting year, you may use the 
``before'' value for the missing data substitution. If, for a particular 
parameter, no quality-assured data are available prior to the missing 
data incident, the substitute data value shall be the first quality-
assured value obtained after the missing data period.
    (c) For missing CO2, CO, O2, CH4, 
or N2O concentrations, gas flow rate, and percent moisture, 
the substitute data values shall be the best available estimate(s) of 
the parameter(s), based on all available process data (e.g., processing 
rates, operating hours, etc.). The owner or operator shall document and 
keep records of the procedures used for all such estimates.

    (a) You must obtain a monthly grab sample of phosphate rock directly 
from the rock being fed to the process line before it enters the mill 
using one of the following methods. You may conduct the representative 
bulk sampling using a method published by a consensus standards 
organization, or you may use industry consensus standard practice 
methods, including but not limited to the Phosphate Mining States 
Methods Used and Adopted by the Association of Fertilizer and Phosphate 
Chemists (AFPC). If phosphate rock is obtained from more than one origin 
in a month, you must obtain a sample from each origin of rock or obtain 
a composite representative sample.
    (b) You must determine the carbon dioxide or inorganic carbon 
content of each monthly grab sample of phosphate rock (consumed in the 
production of phosphoric acid). You may use a method published by a 
consensus standards organization, or you may use industry consensus 
standard practice methods, including but not limited to the Phosphate 
Mining States Methods Used and Adopted by AFPC.
    (c) You must determine the mass of phosphate rock consumed each 
month (by origin) in each wet-process phosphoric acid process line. You 
can use existing plant procedures that are used for accounting purposes 
(such as sales records) or you can use data from existing monitoring 
equipment that is used to measure total mass flow of phosphorous-bearing 
feed under 40 CFR part 60 or part 63.

Sec. 98.265  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable, a substitute data 
value for the missing parameter must be used in the calculations as 
specified in paragraphs (a) and (b) of this section.
    (a) For each missing value of the inorganic carbon content or 
CO2 content of phosphate rock (by origin), you must use the 
appropriate default factor provided in Table Z-1 of this subpart. 
Alternatively, you must determine a substitute data value by calculating 
the arithmetic average of the quality-assured values of inorganic carbon 
contents or CO2 contents of phosphate rock of origin i (see 
Equation Z-1a or Z-1b of this subpart) from samples immediately 
preceding and immediately following the missing data incident. If no 
quality-assured data on inorganic carbon contents or CO2 
contents of phosphate rock of origin i are available prior to the 
missing data incident, the substitute data value shall be the first 
quality-assured value for inorganic carbon contents or CO2 
contents for phosphate rock of origin i obtained after the missing data 
period.
    (b) For each missing value of monthly mass consumption of phosphate 
rock (by origin), you must use the best available estimate based on all 
available process data or data used for accounting purposes.

Sec. 98.274  Monitoring and QA/QC requirements.

    (a) Each facility subject to this subpart must quality assure the 
GHG emissions data according to the applicable requirements in Sec. 
98.34. All QA/QC data must be available for inspection upon request.
    (b) Fuel properties needed to perform the calculations in Equations 
AA-1 and AA-2 of this subpart must be determined according to paragraphs 
(b)(1) through (b)(3) of this section.
    (1) High heat values of black liquor must be determined no less than 
annually using T684 om-06 Gross Heating Value of Black Liquor, TAPPI 
(incorporated by reference, see Sec. 98.7). If measurements are 
performed more frequently than annually, then the high heat value used 
in Equation AA-1 of this subpart must be based on the average of the 
representative measurements made during the year.
    (2) The annual mass of spent liquor solids must be determined using 
either of the methods specified in paragraph (b)(2)(i) or (b)(2)(ii) of 
this section.
    (i) Measure the mass of spent liquor solids annually (or more 
frequently) using T-650 om-05 Solids Content of Black Liquor, TAPPI 
(incorporated by reference in Sec. 98.7). If measurements are performed 
more frequently than annually, then the mass of spent liquor solids used 
in Equation AA-1 of this subpart must be based on the average of the 
representative measurements made during the year.
    (ii) Determine the annual mass of spent liquor solids based on 
records of measurements made with an online measurement system that 
determines the mass of spent liquor solids fired in a chemical recovery 
furnace or chemical recovery combustion unit.

[[Page 966]]

    (3) Carbon analyses for spent pulping liquor must be determined no 
less than annually using ASTM D5373-08 Standard Test Methods for 
Instrumental Determination of Carbon, Hydrogen, and Nitrogen in 
Laboratory Samples of Coal (incorporated by reference, see Sec. 98.7). 
If measurements using ASTM D5373-08 are performed more frequently than 
annually, then the spent pulping liquor carbon content used in Equation 
AA-2 of this subpart must be based on the average of the representative 
measurements made during the year.
    (c) Each facility must keep records that include a detailed 
explanation of how company records of measurements are used to estimate 
GHG emissions. The owner or operator must also document the procedures 
used to ensure the accuracy of the measurements of fuel, spent liquor 
solids, and makeup chemical usage, including, but not limited to 
calibration of weighing equipment, fuel flow meters, and other 
measurement devices. The estimated accuracy of measurements made with 
these devices must be recorded and the technical basis for these 
estimates must be provided. The procedures used to convert spent pulping 
liquor flow rates to units of mass (i.e., spent liquor solids firing 
rates) also must be documented.
    (d) Records must be made available upon request for verification of 
the calculations and measurements.



Sec. 98.275  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation or if a required sample is not 
taken), a substitute data value for the missing parameter shall be used 
in the calculations, according to the requirements of paragraphs (a) 
through (c) of this section:
    (a) There are no missing data procedures for measurements of heat 
content and carbon content of spent pulping liquor. A re-test must be 
performed if the data from any annual measurements are determined to be 
invalid.
    (b) For missing measurements of the mass of spent liquor solids or 
spent pulping liquor flow rates, use the lesser value of either the 
maximum mass or fuel flow rate for the combustion unit, or the maximum 
mass or flow rate that the fuel meter can measure. Alternatively, 
records of the daily spent liquor solids firing rate obtained to comply 
with Sec. 63.866(c)(1) of this chapter may be used, adjusting for the 
duration of the missing measurements, as appropriate.
    (c) For the use of makeup chemicals (carbonates), the substitute 
data value shall be the best available estimate of makeup chemical 
consumption, based on available data (e.g., past accounting records, 
production rates). The owner or operator shall document and keep records 
of the procedures used for all such estimates.

CO2 emissions factor:
[GRAPHIC] [TIFF OMITTED] TR30OC09.115

Where:

EFCO2,n = CO2 emissions factor in month n (metric 
          tons CO2/metric ton of petroleum coke consumed).
0.65 = Adjustment factor for the amount of carbon in silicon carbide 
          product (assuming 35 percent of carbon input is in the carbide 
          product).
CCFn = Carbon content factor for petroleum coke consumed in 
          month n from the supplier or as measured by the applicable 
          method incorporated by reference in Sec. 98.7 according to

98.7).



Sec. 98.285  Procedures for estimating missing data.

    For the petroleum coke input procedure in Sec. 98.283(b), a 
complete record of all measured parameters used in the GHG emissions 
calculations is required (e.g., carbon content values, etc.). 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 the paragraphs (a) and (b) of this section. 
You must document and keep records of the procedures used for all such 
estimates.
    (a) For each missing value of the monthly carbon content of 
petroleum coke, the substitute data value shall be the arithmetic 
average of the quality-assured values of carbon contents immediately 
preceding and immediately following the missing data incident. If no 
quality-assured data on carbon contents are available prior to the 
missing data incident, the substitute data value shall be the first 
quality-assured value for carbon contents obtained after the missing 
data period.
    (b) For each missing value of the monthly petroleum coke 
consumption, the substitute data value shall be the best available 
estimate of the petroleum coke consumption based on all available 
process data or information used for accounting purposes (such as 
purchase records).

Sec. 98.294  Monitoring and QA/QC requirements.

    Section 98.293 provides three different procedures for emission 
calculations. The appropriate paragraphs (a) through (c) of this section 
should be used for the procedure chosen.
    (a) If you determine your emissions using Sec. 98.293(b)(2) 
(Equation CC-1 of this subpart) you must:
    (1) Determine the monthly inorganic carbon content of the trona from 
a weekly composite analysis for each soda ash manufacturing line, using 
a modified version of ASTM E359-00 (Reapproved 2005)e1, Standard Test 
Methods for Analysis of Soda Ash (Sodium Carbonate) (incorporated by 
reference, see Sec. 98.7). ASTM E359-00(Reapproved 2005) e1 is designed 
to measure the total alkalinity in soda ash not in trona. The modified 
method referred to

[[Page 974]]

above adjusts the regular ASTM method to express the results in terms of 
trona. Although ASTM E359-00 (Reapproved 2005) e1 uses manual titration, 
suitable autotitrators may also be used for this determination.
    (2) Measure the mass of trona input to each soda ash manufacturing 
line on a monthly basis using belt scales or methods used for accounting 
purposes.
    (3) Document the procedures used to ensure the accuracy of the 
monthly measurements of trona consumed.
    (b) If you calculate CO2 process emissions based on soda 
ash production (Sec. 98.293(b)(2) Equation CC-2 of this subpart), you 
must:
    (1) Determine the inorganic carbon content of the soda ash (i.e., 
soda ash purity) using ASTM E359-00 (Reapproved 2005) e1 Standard Test 
Methods for Analysis of Soda Ash (Sodium Carbonate) (incorporated by 
reference, see Sec. 98.7). Although ASTM E359-00 (Reapproved 2005) e1 
uses manual titration, suitable autotitrators may also be used for this 
determination.
    (2) Measure the mass of soda ash produced by each soda ash 
manufacturing line on a monthly basis using belt scales, by weighing the 
soda ash at the truck or rail loadout points of your facility, or 
methods used for accounting purposes.
    (3) Document the procedures used to ensure the accuracy of the 
monthly measurements of soda ash produced.
    (c) If you calculate CO2 emissions using the site-
specific emission factor method in Sec. 98.293(b)(3), you must:
    (1) Conduct an annual performance test that is based on 
representative performance (i.e., performance based on normal operating 
conditions) of the affected process.
    (2) Sample the stack gas and conduct three emissions test runs of 1 
hour each.
    (3) Conduct the stack test using EPA Method 3A at 40 CFR part 60, 
appendix A-2 to measure the CO2 concentration, Method 2, 2A, 
2C, 2D, or 2F at 40 CFR part 60, appendix A-1 or Method 26 at 40 CFR 
part 60, appendix A-2 to determine the stack gas volumetric flow rate. 
All QA/QC procedures specified in the reference test methods and any 
associated performance specifications apply. For each test, the facility 
must prepare an emission factor determination report that must include 
the items in paragraphs (c)(3)(i) through (c)(3)(iii) of this section.
    (i) Analysis of samples, determination of emissions, and raw data.
    (ii) All information and data used to derive the emissions 
factor(s).
    (iii) You must determine the average process vent flow rate from the 
mine water stripper/evaporater during each test and document how it was 
determined.
    (4) You must also determine the annual vent flow rate from the mine 
water stripper/evaporater from monthly information using the same plant 
instruments or procedures used for accounting purposes (i.e., volumetric 
flow meter).

Sec. 98.295  Procedures for estimating missing data.

    For the emission calculation methodologies in Sec. 98.293(b)(2) and 
(b)(3), a complete record of all measured parameters used in the GHG 
emissions calculations is required (e.g., inorganic carbon content 
values, etc.). 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 the 
paragraphs (a) through (d) of this section. You must document and keep 
records of the procedures used for all such missing value estimates.
    (a) For each missing value of the weekly composite of inorganic 
carbon content of either soda ash or trona, the substitute data value 
shall be the arithmetic average of the quality-assured values of 
inorganic carbon contents from the week immediately preceding and the 
week immediately following the missing data incident. If no quality-
assured data on inorganic carbon contents are available prior to the 
missing data incident, the substitute data value shall be the first 
quality-assured value for carbon contents obtained after the missing 
data period.
    (b) For each missing value of either the monthly soda ash production 
or the trona consumption, the substitute data

[[Page 975]]

value shall be the best available estimate(s) of the parameter(s), based 
on all available process data or data used for accounting purposes.
    (c) For each missing value collected during the performance test 
(hourly CO2 concentration, stack gas volumetric flow rate, or 
average process vent flow from mine water stripper/evaporator during 
performance test), you must repeat the annual performance test following 
the calculation and monitoring and QA/QC requirements under Sec. Sec. 
98.293(b)(3) and 98.294(c).
    (d) For each missing value of the monthly process vent flow rate 
from mine water stripper/evaporator, the subsititute data value shall be 
the best available estimate(s) of the parameter(s), based on all 
available process data or the lesser of the maximum capacity of the 
system or the maximum rate the meter can measure.

year:
    (1) Ensure that cylinders returned to the gas supplier are 
consistently weighed on a scale that is certified to be accurate and 
precise to within 2 pounds of true weight and is periodically 
recalibrated per the manufacturer's specifications. Either measure 
residual gas (the amount of gas remaining in returned cylinders) or have 
the gas supplier measure it. If the gas supplier weighs the residual 
gas, obtain from the gas supplier a detailed monthly accounting, within 
2 pounds, of residual gas amounts in the cylinders 
returned to the gas supplier.
    (2) Ensure that cylinders weighed for the beginning and end of year 
inventory measurements are weighed on a scale that is certified to be 
accurate and precise to within 2 pounds of true weight and is 
periodically recalibrated per the manufacturer's specifications. All 
scales used to measure quantities that are to be reported under Sec. 
98.306 must be calibrated using calibration procedures specified by the 
scale manufacturer. Calibration must be performed prior to the first 
reporting year. After the initial calibration, recalibration must be 
performed at the minimum frequency specified by the manufacturer.
    (3) Ensure all substations have provided information to the manager 
compiling the emissions report (if it is not already handled through an 
electronic inventory system).
    (d) GHG Monitoring Plans, as described in Sec. 98.3(g)(5), must be 
completed by April 1, 2011.

Sec. 98.315  Procedures for estimating missing data.

    For the petroleum coke input procedure in Sec. 98.313(b), a 
complete record of all measured parameters used in the GHG emissions 
calculations is required (e.g., carbon content values, etc.). Therefore, 
whenever the monitoring and quality assurance procedures in Sec. 98.315 
cannot be followed, a substitute data value for the missing parameter 
shall be used in the calculations as specified in the paragraphs (a) 
through (c) of this section. You must document and keep records of the 
procedures used for all such estimates.
    (a) For each missing value of the monthly carbon content of calcined 
petroleum coke the substitute data value shall be the arithmetic average 
of the quality-assured values of carbon contents for the month 
immediately preceding and the month immediately following the missing 
data incident. If no quality-assured data on carbon contents are 
available prior to the missing data incident, the substitute data value 
shall be the first quality-assured value for carbon contents obtained 
after the missing data period.
    (b) For each missing value of the monthly calcined petroleum coke 
consumption and/or carbon-containing waste, the substitute data value 
shall be the best available estimate of the monthly petroleum coke 
consumption based on all available process data or information used for 
accounting purposes (such as purchase records).
    (c) For each missing value of the carbon content of carbon-
containing waste, you must conduct a new analysis following the 
procedures in Sec. 98.314(f).

and any underground mines under development that have operational pre-
mining degasification systems. An underground coal mine is a mine at 
which coal is produced by tunneling into the earth to the coalbed, which 
is then mined with underground mining equipment such as cutting machines 
and continuous, longwall, and shortwall mining machines, and transported 
to the surface. Underground coal mines are categorized as active if any 
one of the following five conditions apply:
    (1) Mine development is underway.
    (2) Coal has been produced within the last 90 days.
    (3) Mine personnel are present in the mine workings.
    (4) Mine ventilation fans are operative.
    (5) The mine is designated as an ''intermittent'' mine by the Mine 
Safety and Health Administration (MSHA).
    (b) This source category includes the following:
    (1) Each ventilation system shaft or vent hole, including both those 
points where mine ventilation air is emitted and those where it is sold, 
used onsite, or otherwise destroyed (including by ventilation air 
methane (VAM) oxidizers).
    (2) Each degasification system well or gob gas vent hole, including 
degasification systems deployed before, during, or after mining 
operations are conducted in a mine area. This includes both those wells 
and vent holes where coal bed gas is emitted, and those where the gas is 
sold, used onsite, or otherwise destroyed (including by flaring).
    (c) This source category does not include abandoned or closed mines, 
surface coal mines, or post-coal mining activities (e.g., storage or 
transportation of coal).

Sec. 98.323  Calculating GHG emissions.

    (a) For each ventilation shaft, vent hole, or centralized point into 
which CH4 from multiple shafts and/or vent holes are 
collected, you must calculate the quarterly CH4 liberated

must measure CH4 content, flow rate, temperature, pressure, 
and moisture content of the gas using the procedures outlined in Sec. 
98.324.

          flow rate meter. If a flow rate meter is used and the meter 
          automatically corrects to standard temperature and pressure, 
          then use scfm and replace ``520[deg]R/T x P/1 atm'' with 
          ``1''.
MCF = Moisture correction factor for the measurement period, volumetric 
          basis.

n = The number of days in the quarter where active ventilation of mining 
          operations is taking place at the monitoring point. To obtain 
          the number of days in the quarter, divide the total number of 
          hours in the quarter where active ventilation is taking place 
          by 24 hours per day.

    (2) Values of V, C, T, P, and, if applicable, (fH2O), 
must be based on measurements taken at least once each quarter with no 
fewer than 6 weeks between measurements. If measurements are taken more 
frequently than once per quarter, then use the average value for all 
measurements taken. If continuous measurements are taken, then use the 
average value over the time period of continuous monitoring.

[[Page 985]]

    (3) If a facility has more than one monitoring point, the facility 
must calculate total CH4 liberated from ventilation systems 
(CH4VTotal) as the sum of the CH4 from all 
ventilation monitoring points in the mine, as follows:

Where:

CH4VTotal = Total quarterly CH4 liberated from 
          ventilation systems (metric tons CH4).
CH4V = Quarterly CH4 liberated from each 
          ventilation monitoring point (metric tons CH4).

    (b) For each monitoring point in the degasification system (this 
could be at each degasification well and/or vent hole, or at more 
centralized points into which CH4 from multiple wells and/or

          monitoring point, based on sampling or a flow rate meter 
          (acfm). If a flow rate meter is used and the meter 
          automatically corrects to standard temperature and pressure, 
          then use scfm and replace ``520[deg]R/Ti x 
          Pi/1 atm'' with ``1''.

          week when the degasification system is in operation at that 
          monitoring point (%).
n = The number of days in the week that the system is operational at 
          that measurement point. To obtain the number of days in the 
          week, divide the total number of hours that the system is

0.454/1,000 = Conversion factor (metric ton/lb).

    (1) Values for V, C, T, P, and, if applicable, (fH2O), 
must be based on measurements taken at least once each calendar week 
with at least 3 days between measurements. If measurements are taken 
more frequently than once per week, then use the average value for all 
measurements taken that week. If continuous measurements are taken, then 
use the average values over the time period of continuous monitoring 
when the continuous monitoring equipment is properly functioning.
    (2) Quarterly total CH4 liberated from degasification 
systems for the mine must be determined as the sum of CH4 
liberated determined at each of the monitoring points in the mine, 
summed over the number of weeks in the quarter, as follows:

oxidation), you must calculate the quarterly CH4 destroyed 
for each destruction device and each point of offsite transport to a 
destruction device, using Equation FF-5 of this section. You must 
measure CH4 content and flow rate according to the provisions

Sec. 98.324  Monitoring and QA/QC requirements.

    (a) For calendar year 2011 monitoring, the facility may submit a 
request to the Administrator to use one or more best available 
monitoring methods as listed in Sec. 98.3(d)(1)(i) through (iv). The 
request must be submitted no later than October 12, 2010 and must 
contain the information in Sec. 98.3(d)(2)(ii). To obtain approval, the 
request must demonstrate to the Administrator's satisfaction that it is 
not reasonably feasible to acquire, install, and operate a required 
piece of monitoring equipment by January 1, 2011. The use of best 
available monitoring methods will not be approved beyond December 31, 
2011.
    (b) For CH4 liberated from ventilation systems, determine 
whether CH4 will be monitored from each ventilation shaft and 
vent hole, from a centralized monitoring point, or from a combination of 
the two options. Operators are allowed flexibility for aggregating 
emissions from more than one ventilation point, as long as emissions 
from all are addressed, and the methodology for calculating total 
emissions documented. Monitor by one of the following options:
    (1) Collect quarterly or more frequent grab samples (with no fewer 
than 6 weeks between measurements) for methane concentration and make 
quarterly measurements of flow rate, temperature, pressure, and, if 
applicable, moisture content. The sampling and measurements must be made 
at the same locations as Mine Safety and Health Administration (MSHA) 
inspection samples are taken, and should be taken when the mine is 
operating under normal conditions. You must follow MSHA sampling 
procedures as set forth in the MSHA Handbook entitled, Coal Mine Safety 
and Health General Inspection Procedures Handbook, Handbook Number: 
PH16-V-1 (incorporated by reference, see Sec. 98.7). You must record 
the date of sampling, flow, temperature, pressure, and moisture 
measurements, the methane concentration (percent), the bottle number of 
samples collected, and the location of the measurement or collection.
    (2) Obtain results of the quarterly (or more frequent) testing 
performed by MSHA for the methane flowrate. At the same location and 
within seven days of the MSHA sampling, make measurements of temperature 
and pressure using the same procedures specified in paragraph (b)(1) of 
this section. The annual average barometric pressure from the nearest 
National Oceanic and Atmospheric Administration (NOAA) weather service 
station may be used as a default for pressure. If the MSHA data for 
methane flow is provided in the units of actual cubic feet of methane 
per day, the methane flow data is inserted into Equation FF-1 of this 
section in place of the value for V and the variables MCF, C/100%, and 
1440 are removed from the equation.
    (3) Monitor emissions through the use of one or more continuous 
emission monitoring systems (CEMS). If operators use CEMS as the basis 
for emissions reporting, they must provide documentation on the process 
for using data obtained from their CEMS to estimate emissions from their 
mine ventilation systems.
    (c) For CH4 liberated at degasification systems, 
determine

[[Page 988]]

whether CH4 will be monitored from each well and gob gas vent 
hole, from a centralized monitoring point, or from a combination of the 
two options. Operators are allowed flexibility for aggregating emissions 
from more than one well or gob gas vent hole, as long as emissions from 
all are addressed, and the methodology for calculating total emissions 
is documented. Monitor both gas volume and methane concentration by one 
of the following two options:
    (1) Monitor emissions through the use of one or more continuous 
emissions monitoring systems (CEMS). If operators use CEMS as the basis 
for emissions reporting, they must provide documentation on the process 
for using data obtained from their CEMS to estimate emissions from their 
mine ventilation systems.
    (2) Collect weekly (once each calendar week, with at least three 
days between measurements) or more frequent samples, for all 
degasification wells and gob gas vent holes. Determine weekly or more 
frequent flow rates, methane concentration, temperature, and pressure 
from these degasification wells and gob gas vent holes. Methane 
composition should be determined either by submitting samples to a lab 
for analysis, or from the use of methanometers at the degasification 
monitoring site. Follow the sampling protocols for sampling of methane 
emissions from ventilation shafts, as described in Sec. 98.324(b)(1). 
You must record the date of sampling, flow, temperature, pressure, and 
moisture measurements, the methane concentration (percent), the bottle 
number of samples collected, and the location of the measurement or 
collection.
    (3) If the CH4 concentration is determined on a dry basis 
and flow is determined on a wet basis or CH4 concentration is 
determined on a wet basis and flow is determined on a dry basis, and the 
flow meter does not automatically correct for moisture content, 
determine the moisture content in the gas in a location near or 
representative of the location of:
    (i) The gas flow meter at least once each calendar week; if 
measuring with CEMS. If only one measurement is made each calendar week, 
there must be at least three days between measurements; and
    (ii) The grab sample, if using grab samples, at the time of the 
sample.
    (d) Monitoring must adhere to one of the methods specified in 
paragraphs (d)(1) through (d)(2) of this section.
    (1) ASTM D1945-03, Standard Test Method for Analysis of Natural Gas 
by Gas Chromatography; ASTM D1946-90 (Reapproved 2006), Standard 
Practice for Analysis of Reformed Gas by Gas Chromatography; ASTM D4891-
89 (Reapproved 2006), Standard Test Method for Heating Value of Gases in 
Natural Gas Range by Stoichiometric Combustion; or ASTM UOP539-97 
Refinery Gas Analysis by Gas Chromatography (incorporated by reference, 
see Sec. 98.7).
    (2) As an alternative to the gas chromatography methods provided in 
paragraph (d)(1) of this section, you may use gaseous organic 
concentration analyzers and a correction factor to calculate the 
CH4 concentration following the requirements in paragraphs 
(d)(2)(i) through (d)(2)(iii) of this section.
    (i) Use Method 25A or 25B at 40 CFR part 60, appendix A-7 to 
determine gaseous organic concentration as required in Sec. 98.323 and 
in paragraphs (b) and (c) of this section. You must calibrate the 
instrument with CH4 and determine the total gaseous organic 
concentration as carbon (or as CH4; K = 1 in Equation 25A-1 
of Method 25A at 40 CFR part 60, appendix A-7).
    (ii) Determine a correction factor that will be used with the 
gaseous organic concentrations measured in paragraph (i) of this 
section. The correction factor must be determined at the routine 
sampling location no less frequently than once a reporting year 
following the requirements in paragraphs (d)(2)(ii)(A) through 
(d)(2)(ii)(C) of this section.
    (A) Take a minimum of three grab samples of the gas with a minimum 
of 20 minutes between samples and determine the methane composition of 
the gas using one of the methods specified in paragraph (d)(1) of this 
section.
    (B) As soon as practical after each grab sample is collected and 
prior to the collection of a subsequent grab sample, determine the 
gaseous organic concentration of the gas using either Method 25A or 25B 
at 40 CFR part 60,

[[Page 989]]

appendix A-7 as specified in paragraph (d)(2)(i) of this section.
    (C) Determine the arithmetic average methane concentration and the 
arithmetic average gaseous organic concentration of the samples analyzed 
according to paragraphs (d)(2)(ii)(A) and (d)(2)(ii)(B) of this section, 
respectively, and calculate the non-methane organic carbon correction 
factor as the ratio of the average methane concentration to the average 
total gaseous organic concentration. If the ratio exceeds 1, use 1 for 
the correction factor.
    (iii) Calculate the CH4 concentration as specified in 
Equation FF-9 of this section:

Sec. 98.325  Procedures for estimating missing data.

    (a) A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation or if a required fuel sample is not 
taken), a substitute data value for the missing parameter shall be used 
in the calculations, in accordance with paragraph (b) of this section.

degasification systems, 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. If, for a particular parameter, no quality-assured data are 
available prior to the missing data incident, the substitute data value 
shall be the first quality-assured value obtained after the missing data 
period.

procedures in Sec. 98.335(b) if data are missing.
    (b) For missing records of the annual mass of carbon-containing 
inputs using the carbon input procedure in Sec. 98.333(b), the

78 FR 71968, Nov. 29, 2013]



Sec. 98.341  Reporting threshold.

    You must report GHG emissions under this subpart if your facility 
contains a MSW landfill and the facility meets the requirements of Sec. 
98.2(a)(1).



Sec. 98.342  GHGs to report.

    (a) You must report CH4 generation and CH4 
emissions from landfills.
    (b) You must report CH4 destruction resulting from

Sec. 98.343  Calculating GHG emissions.

    (a) For all landfills subject to the reporting requirements of this 
subpart, calculate annual modeled CH4 generation according to 
the applicable requirements in paragraphs (a)(1) through (a)(3) of this 
section.
    (1) Calculate annual modeled CH4 generation using 
Equation HH-1 of this section.
[GRAPHIC] [TIFF OMITTED] TR28OC10.033

Where:

GCH4 = Modeled methane generation rate in reporting year T 
          (metric tons CH4).
x = Year in which waste was disposed.
S = Start year of calculation. Use the year 1960 or the opening year of 
          the landfill, whichever is more recent.
T = Reporting year for which emissions are calculated.
WX = Quantity of waste disposed in the landfill in year x 
          from measurement data, tipping fee receipts, or other company 
          records (metric tons, as received (wet weight)).
MCF = Methane correction factor (fraction). Use the default value of 1 
          unless there is active aeration of waste within the landfill 
          during the reporting year. If there is active aeration of 
          waste within the landfill during the reporting year, use 
          either the default value of 1 or select an alternative value 
          no less than 0.5 based on site-specific aeration parameters.
DOC = Degradable organic carbon from Table HH-1 of this subpart 
          [fraction (metric tons C/metric ton waste)].
DOCF = Fraction of DOC dissimilated (fraction). Use the 
          default value of 0.5.
F = Fraction by volume of CH4 in landfill gas from 
          measurement data for the current reporting year, if available 
          (fraction, dry basis, corrected to 0% oxygen); otherwise, use 
          the default of 0.5.
k = Rate constant from Table HH-1 to this subpart (yr-1). 
          Select the most applicable k value for the majority of the 
          past 10 years (or operating life, whichever is shorter).

    (2) For years when material-specific waste quantity data are 
available, apply Equation HH-1 of this section for each waste quantity 
type and sum the CH4 generation rates for all waste types to 
calculate the total modeled CH4 generation rate for the 
landfill. Use the appropriate parameter values for k, DOC, MCF, 
DOCF, and F shown in Table HH-1 of this subpart. The annual 
quantity of each type of waste disposed must be calculated as the sum of 
the

[[Page 997]]

daily quantities of waste (of that type) disposed. You may use the bulk 
waste parameters for a portion of your waste materials when using the 
material-specific modeling approach for mixed waste streams that cannot 
be designated to a specific material type. For years when waste 
composition data are not available, use the bulk waste parameter values 
for k and DOC in Table HH-1 to this subpart for the total quantity of 
waste disposed in those years.
    (3) Beginning in the first emissions reporting year and for each 
year thereafter, if scales are in place, you must determine the annual 
quantity of waste (in metric tons as received, i.e., wet weight) 
disposed of in the landfill using paragraph (a)(3)(i) of this section 
for all containers and for all vehicles used to haul waste to the 
landfill, except for passenger cars, light duty pickup trucks, or waste 
loads that cannot be measured using the scales due to physical 
limitations (load cannot physically access or fit on the scale) and/or 
operational limitations of the scale (load exceeding the limits or 
sensitivity range of the scale). If scales are not in place, you must 
use paragraph (a)(3)(ii) of this section to determine the annual 
quantity of waste disposed. For waste hauled to the landfill in 
passenger cars or light duty pickup trucks, you may use either paragraph 
(a)(3)(i) or paragraph (a)(3)(ii) of this section to determine the 
annual quantity of waste disposed. For loads that cannot be measured 
using the scales due to physical and/or operational limitations of the 
scale, you must use paragraph (a)(3)(ii) of this section or similar 
engineering calculations to determine the annual quantity of waste 
disposed. The approach used to determine the annual quantity of waste 
disposed of must be documented in the monitoring plan.
    (i) Use direct mass measurements of each individual load received at 
the landfill using either of the following methods:
    (A) Weigh using mass scales each vehicle or container used to haul 
waste as it enters the landfill or disposal area; weigh using mass 
scales each vehicle or container after it has off-loaded the waste; 
determine the quantity of waste received from the individual load as the 
difference in the two mass measurements; and determine the annual 
quantity of waste received as the sum of all waste loads received during 
the year. Alternatively, you may determine annual quantity of waste by 
summing the weights of all vehicles and containers entering the landfill 
and subtracting from it the sum of all the weights of vehicles and 
containers after they have off-loaded the waste in the landfill.
    (B) Weigh using mass scales each vehicle or container used to haul 
waste as it enters the landfill or disposal area; determine a 
representative tare weight by vehicle or container type by weighing no 
less than 5 of each type of vehicle or container after it has off-loaded 
the waste; determine the quantity of waste received from the individual 
load as the difference between the measured weight in and the tare 
weight determined for that container/vehicle type; and determine the 
annual quantity of waste received as the sum of all waste loads received 
during the year.
    (ii) Determine the working capacity in units of mass for each type 
of container or vehicle used to haul waste to the landfill (e.g., using 
volumetric capacity and waste density measurements; direct measurement 
of a selected number of passenger vehicles and light duty pick-up 
trucks; or similar methods); record the number of loads received at the 
landfill by vehicle/container type; calculate the annual mass per 
vehicle/container type as the mass product of the number of loads of 
that vehicle/container multiplied by its working capacity; and calculate 
the annual quantity of waste received as the sum of the annual mass per 
vehicle/container type across all of the vehicle/container types used to 
haul waste to the landfill.
    (4) For years prior to the first emissions reporting year, use 
methods in paragraph (a)(3) of this section when waste disposal quantity 
data are readily available. When waste disposal quantity data are not 
readily available, WX shall be estimated using one of the 
applicable methods in paragraphs (a)(4)(i) through (a)(4)(iii) of this 
section. You must determine which method is most applicable to the 
conditions

[[Page 998]]

and disposal history of your facility. Historical waste disposal 
quantities should only be determined once, as part of the first annual 
report, and the same values should be used for all subsequent annual 
reports, supplemented by the next year's data on new waste disposal.
    (i) Assume all prior years waste disposal quantities are the same as 
the waste quantity in the first year for which waste quantities are 
available.
    (ii) Use the estimated population served by the landfill in each 
year, the values for national average per capita waste disposal rates 
found in Table HH-2 to this subpart, and calculate the waste quantity 
landfilled using Equation HH-2 of this section.
[GRAPHIC] [TIFF OMITTED] TR28OC10.034

where:

WX = Quantity of waste placed in the landfill in year x 
          (metric tons, wet basis).

          population, census data, or other estimates (capita).
WDRX = Average per capita waste disposal rate for year x from 
          Table HH-2 to this subpart (metric tons per capita per year, 
          wet basis; tons/cap/yr).

    (iii) Use a constant average waste disposal quantity calculated 
using Equation HH-3 of this section for each year the landfill was in 
operation (i.e., from the first year accepting waste until the last year 
for which waste disposal data is unavailable, inclusive).
[GRAPHIC] [TIFF OMITTED] TR28OC10.035

where:

WX = Quantity of waste placed in the landfill in year x 
          (metric tons, wet basis).
LFC = Landfill capacity or, for operating landfills, capacity of the 
          landfill used (or the total quantity of waste-in-place) at the 
          end of the year prior to the year when waste disposal data are 
          available from design drawings or engineering estimates 
          (metric tons).
YrData = Year in which the landfill last received waste or, for 
          operating landfills, the year prior to the first reporting 
          year when waste disposal data is first available from company 
          records, or best available data.
YrOpen = Year in which the landfill first received waste from company 
          records or best available data. If no data are available for 
          estimating YrOpen for a closed landfill, use 30 years as the 
          default operating life of the landfill.

    (b) For landfills with gas collection systems, calculate the 
quantity of CH4 destroyed according to the requirements in 
paragraphs (b)(1) and (b)(2) of this section.
    (1) If you continuously monitor the flow rate, CH4 
concentration, temperature, pressure, and, if necessary, moisture 
content of the landfill gas that is collected and routed to a 
destruction device (before any treatment equipment) using a monitoring 
meter specifically for CH4 gas, as specified in Sec. 98.344, 
you must use this monitoring system and calculate the quantity of 
CH4 recovered for destruction using Equation HH-4 of this 
section. A fully integrated system that directly reports CH4 
content requires no other calculation than summing the results of all 
monitoring periods for a given year.
[GRAPHIC] [TIFF OMITTED] TR29NO13.020

where:

R = Annual quantity of recovered CH4 (metric tons 
          CH4).
N = Total number of measurement periods in a year. Use daily averaging 
          periods for a continuous monitoring system and N = 365 (or N = 
          366 for leap years). For monthly sampling, as provided in 
          paragraph (b)(2) of this section, use N = 12.
n = Index for measurement period.
(V)n = Cumulative volumetric flow for the measurement period 
          in actual cubic feet (acf). If the flow rate meter 
          automatically corrects for temperature and pressure, replace 
          ``520[deg]R/(T)n x (P)n/1 atm'' with 
          ``1''.
(KMC)n = Moisture correction term for the 
          measurement period, volumetric basis, as follows: 
          (KMC)n = 1 when (V)n and 
          (C)n are both measured on a dry basis or if both 
          are measured on a wet basis; (KMC)n = 
          [1-

[[Page 999]]

          (fH2O)n] when (V)n 
          is measured on a wet basis and (C)n is measured on 
          a dry basis; and (KMC)n = 1/[1-
          (fH2O)n] when (V)n is 
          measured on a dry basis and (C)n is measured on a 
          wet basis.

    (2) If you do not continuously monitor according to paragraph (b)(1) 
of this section, you must determine the flow rate, CH4 
concentration, temperature, pressure, and moisture content of the 
landfill gas that is collected and routed to a destruction device 
(before any treatment equipment) according to the requirements in 
paragraphs (b)(2)(i) through (b)(2)(iii) of this section and calculate 
the quantity of CH4 recovered for destruction using Equation 
HH-4 of this section.
    (i) Continuously monitor gas flow rate and determine the cumulative 
volume of landfill gas each month and the cumulative volume of landfill 
gas each year that is collected and routed to a destruction device 
(before any treatment equipment). Under this option, the gas flow meter 
is not required to automatically correct for temperature, pressure, or, 
if necessary, moisture content. If the gas flow meter is not equipped 
with automatic correction for temperature, pressure, or, if necessary, 
moisture content, you must determine these parameters as specified in 
paragraph (b)(2)(iii) of this section.
    (ii) Determine the CH4 concentration in the landfill gas 
that is collected and routed to a destruction device (before any 
treatment equipment) in a location near or representative of the 
location of the gas flow meter at least once each calendar month; if 
only one measurement is made each calendar month, there must be at least 
fourteen days between measurements.
    (iii) If the gas flow meter is not equipped with automatic 
correction for temperature, pressure, or, if necessary, moisture 
content:
    (A) Determine the temperature and pressure in the landfill gas that 
is collected and routed to a destruction device (before any treatment 
equipment) in a location near or representative of the location of the 
gas flow meter at least once each calendar month; if only one 
measurement is made each calendar month, there must be at least fourteen 
days between measurements.
    (B) If the CH4 concentration is determined on a dry basis 
and flow is determined on a wet basis or CH4 concentration is 
determined on a wet basis and flow is determined on a dry basis, and the 
flow meter does not automatically correct for moisture content, 
determine the moisture content in the landfill gas that is collected and 
routed to a destruction device (before any treatment equipment) in a 
location near or representative of the location of the gas flow meter at 
least once each calendar month; if only one measurement is made each 
calendar month, there must be at least fourteen days between 
measurements.
    (c) For all landfills, calculate CH4 generation (adjusted 
for oxidation in cover materials) and actual CH4 emissions 
(taking into account any CH4 recovery, and oxidation in cover 
materials) according to the applicable methods in paragraphs (c)(1) 
through (c)(3) of this section.
    (1) Calculate CH4 generation, adjusted for oxidation, 
from the modeled CH4 (GCH4 from Equation HH-1 of 
this section) using Equation HH-5 of this section.

OX = Oxidation fraction. Use the appropriate oxidation fraction default 
          value from Table HH-4 of this subpart.

    (2) For landfills that do not have landfill gas collection systems, 
the CH4

[[Page 1000]]

emissions are equal to the CH4 generation (MG) calculated in 
Equation HH-5 of this section.
    (3) For landfills with landfill gas collection systems, calculate 
CH4 emissions using the methodologies specified in paragraphs

          (metric tons CH4).
GCH4 = Modeled methane generation rate in reporting year from

          CH4 from Equation HH-4 of this section, whichever 
          is greater (metric tons CH4).
N = Number of landfill gas measurement locations (associated with a 
          destruction device or gas sent off-site). If a single

DEn = Destruction efficiency (lesser of manufacturer's 
          specified destruction efficiency and 0.99) for the n\th\ 
          measurement location. If the gas is transported off-site for 
          destruction, use DE = 1. If the volumetric flow and 
          CH4 concentration of the recovered gas is measured 
          at a single location providing landfill gas to multiple 
          destruction devices (including some gas destroyed on-site and 
          some gas sent off-site for destruction), calculate 
          DEn as the arithmetic average of the DE values 
          determined for each destruction device associated with that 
          measurement location.
fDest,n = Fraction of hours the destruction device associated 
          with the n\th\ measurement location was operating during 
          active gas flow calculated as the annual operating hours for 
          the destruction device divided by the annual hours flow was 
          sent to the destruction device as measured at the n\th\ 
          measurement location. If the gas is transported off-site for 
          destruction, use fDest,n= 1. If the volumetric flow 
          and CH4 concentration of the recovered gas is 
          measured at a single location providing landfill gas to 
          multiple destruction devices (including some gas destroyed on-
          site and some gas sent off-site for destruction), calculate 
          fDest,n as the arithmetic average of the 
          fDest values determined for each destruction device

          destruction device or gas sent off-site). If a single 
          monitoring location is used to monitor volumetric flow and 
          CH4 concentration of the recovered gas sent to one 
          or multiple destruction devices, then N = 1.

          of this section for the n\th\ measurement location (metric 
          tons CH4).
CE = Collection efficiency estimated at landfill, taking into account 
          system coverage, operation, and cover system materials from 
          Table HH-3 of this subpart. If area by soil cover type 
          information is not available, use default value of 0.75 (CE4 
          in table HH-3 of this subpart) for all areas under active 
          influence of the collection system.
fRec,n = Fraction of hours the recovery system associated 
          with the n\th\ measurement location was operating (annual 
          operating hours/8760 hours per year or annual operating hours/
          8784 hours per year for a leap year).
OX = Oxidation fraction. Use appropriate oxidation fraction default 
          value from Table HH-4 of this subpart.

          specified destruction efficiency and 0.99) for the n\th\ 
          measurement location. If the gas is transported off-site for 
          destruction, use DE = 1. If the volumetric flow and 
          CH4 concentration of the recovered gas is measured 
          at a single location providing landfill gas to multiple 
          destruction devices (including some gas destroyed on-site and 
          some gas sent off-site for destruction), calculate 
          DEn as the arithmetic average of the DE values 
          determined for each destruction device associated with that 
          measurement location.
fDest,n = Fraction of hours the destruction device associated 
          with the n\th\ measurement location was operating during 
          active gas flow calculated as the annual operating hours for 
          the destruction device divided by the annual hours flow was 
          sent to the destruction device as measured at the n\th\ 
          measurement location. If the gas is transported off-site for 
          destruction, use fDest,n= 1. If the volumetric flow 
          and CH4 concentration of the recovered gas is 
          measured at a single location providing landfill gas to 
          multiple destruction devices (including some gas destroyed on-
          site and some gas sent off-site for destruction), calculate 
          fDest,n as the arithmetic average of the 
          fDest values determined for each destruction device 
          associated with that measurement location.

Sec. 98.345  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation or if a required fuel sample is not 
taken), a substitute data value for the missing parameter shall be used 
in the calculations, according to the requirements in paragraphs (a) 
through (c) of this section.
    (a) For each missing value of the CH4 content, 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. If the ``after'' value is not 
obtained by the end of the reporting year, you may use the ``before'' 
value for the missing data substitution. If, for a particular parameter, 
no quality-assured data are available prior to the missing data 
incident, the substitute data value shall be the first quality-assured 
value obtained after the missing data period.
    (b) For missing gas flow rates, 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. If the ``after'' value is not obtained by the end of the 
reporting year, you may use the ``before'' value for the missing data 
substitution. If, for a particular parameter, no quality-assured data 
are available prior to the missing data incident, the substitute data 
value shall be the

[[Page 1004]]

first quality-assured value obtained after the missing data period.
    (c) For missing daily waste disposal quantity data for disposal in 
the reporting year, the substitute value shall be the average daily 
waste disposal quantity for that day of the week as measured on the week 
before and week after the missing daily data.

Sec. 98.348  Definitions.

    Except as specified in this section, all terms used in this subpart 
have the same meaning given in the Clean Air Act and subpart A of this 
part.
    Construction and demolition (C&D) waste landfill means a solid waste 
disposal facility subject to the requirements of part 257, subparts A or 
B of this chapter that receives construction and demolition waste and 
does not receive hazardous waste (defined in Sec. 261.3 of this 
chapter) or industrial solid waste (defined in Sec. 258.2 of this 
chapter) or municipal solid waste (as defined in Sec. 98.6) other than 
residential lead-based paint waste. A C&D waste landfill typically 
receives any one or more of the following types of solid wastes: 
Roadwork material, excavated material, demolition waste, construction/
renovation waste, and site clearance waste.
    Destruction device means a flare, thermal oxidizer, boiler, turbine, 
internal combustion engine, or any other combustion unit used to destroy 
or oxidize methane contained in landfill gas.
    Final cover means materials used at a landfill to meet final closure 
regulations of the competent federal, state, or local authority.
    Industrial waste landfill means any landfill other than a municipal 
solid waste landfill, a RCRA Subtitle C hazardous waste landfill, or a 
TSCA hazardous waste landfill, in which industrial solid waste, such a 
RCRA Subtitle D wastes (nonhazardous industrial solid waste, defined in 
Sec. 257.2 of this chapter), commercial solid wastes, or conditionally 
exempt small quantity generator wastes, is placed. An industrial waste 
landfill includes all disposal areas at the facility.
    Intermediate or interim cover means the placement of material over 
waste in a landfill for a period of time prior to the disposal of 
additional waste and/or final closure as defined by state regulation, 
permit, guidance or written plan, or state accepted best management 
practice.
    Landfill capacity means the maximum amount of solid waste a landfill 
can accept. For the purposes of this subpart, for landfills that have a 
permit, the landfill capacity can be determined in terms of volume or 
mass in the most recent permit issued by the state, local, or Tribal 
agency responsible for regulating the landfill, plus any in-place waste 
not accounted for in the most recent permit. If the owner or operator 
chooses to convert from volume to mass to determine its capacity, the 
calculation must include a site-specific density.
    Leachate recirculation means the practice of taking the leachate 
collected from the landfill and reapplying it to the landfill by any of 
one of a variety of methods, including pre-wetting of the waste, direct 
discharge into the working face, spraying, infiltration ponds, vertical 
injection wells, horizontal gravity distribution systems, and pressure 
distribution systems.
    Passive vent means a pipe or a system of pipes that allows landfill 
gas to flow naturally, without the use of a fan or similar mechanical 
draft equipment, to the surface of the landfill where an opening or pipe 
(vent) allows for the free flow of landfill gas to the atmosphere or to 
a passive vent flare without diffusion through the top layer of surface 
soil.
    Solid waste has the meaning established by the Administrator 
pursuant to the Solid Waste Disposal Act (42 U.S.C.A. 6901 et seq.).
    Working capacity means the maximum volume or mass of waste that is 
actually placed in the landfill from an individual or representative 
type of container (such as a tank, truck, or roll-off bin) used to 
convey wastes to the landfill, taking into account that the container 
may not be able to be 100 percent filled and/or 100 percent emptied for 
each load.

\a\ Recirculated leachate (in inches/year) is the total volume of leachate recirculated from company records or
  engineering estimates divided by the area of the portion of the landfill containing waste with appropriate
  unit conversions. Alternatively, landfills that use leachate recirculation can elect to use the k value of
  0.057 rather than calculating the recirculated leachate rate.
\b\ Use the lesser value when precipitation plus recirculated leachate is less than 20 inches/year. Use the
  greater value when precipitation plus recirculated leachate is greater than 40 inches/year. Use the average of
  the range of values when precipitation plus recirculated leachate is 20 to 40 inches/year (inclusive).
  Alternatively, landfills that use leachate recirculation can elect to use the greater value rather than
  calculating the recirculated leachate rate.
\c\ Use the lesser value when the potential evapotranspiration rate exceeds the mean annual precipitation rate
  plus recirculated leachate. Use the greater value when the potential evapotranspiration rate does not exceed
  the mean annual precipitation rate plus recirculated leachate. Alternatively, landfills that use leachate
  recirculation can elect to use the greater value rather than assessing the potential evapotranspiration rate
  or recirculated leachate rate.

          treatment process in week w (m\3\/week), measured as specified 
          in Sec. 98.354(d).
CODw = Average weekly concentration of chemical oxygen demand 
          of wastewater entering an anaerobic wastewater treatment 
          process (for week w)(kg/m\3\), measured as specified in Sec. 
          98.354(b) and (c).

    (2) If you measure the concentration of organic material entering an 
anaerobic reactor or anaerobic lagoon using methods for the 
determination of 5-day biochemical oxygen demand (BOD5), then 
estimate annual mass of CH4 generated using Equation II-2 of 
this section.

anaerobic

[[Page 1012]]

lagoon from which some biogas is recovered, estimate the annual mass of 
CH4 recovered according to the requirements in paragraphs 
(c)(1) and (c)(2) of this section. To estimate the annual mass of 
CH4 recovered, you must continuously monitor biogas flow rate 
and determine the volume of biogas each week and the cumulative volume 
of biogas each year that is collected and routed to a destruction device 
as specified in Sec. 98.354(h). If the gas flow meter is not equipped 
with automatic correction for temperature, pressure, or, if necessary, 
moisture content, you must determine these parameters as specified in 
paragraph (c)(2)(ii) of this section.
    (1) If you continuously monitor CH4 concentration (and if 
necessary, temperature, pressure, and moisture content required as 
specified in Sec. 98.354(f)) of the biogas that is collected and routed 
to a destruction device using a monitoring meter specifically for 
CH4 gas, as specified in Sec. 98.354(g), you must use this 
monitoring system and calculate the quantity of CH4 recovered 
for destruction using Equation II-4 of this section. A fully integrated 
system that directly reports CH4 quantity requires only the 
summing of results of all monitoring periods for a given year.

request to the Administrator to use one or more best available 
monitoring methods as listed in Sec. 98.3(d)(1)(i) through (iv). The 
request must be submitted no later than October 12, 2010 and must 
contain the information in Sec. 98.3(d)(2)(ii). To obtain approval, the 
request must demonstrate to the Administrator's satisfaction that it is 
not reasonably feasible to acquire, install, and operate a required 
piece of monitoring equipment by January 1, 2011. The use of best 
available monitoring methods will not be approved beyond December 31, 
2011.

concentration range of the approved method, but the calculated 
concentration of the undiluted wastewater must be used for calculations 
and reporting required by this subpart.
    (c) You must collect samples representing wastewater influent to the 
anaerobic wastewater treatment process, following all preliminary and 
primary treatment steps (e.g., after grit removal, primary 
clarification, oil-water separation, dissolved air flotation, or similar 
solids and oil separation processes). You must collect and analyze 
samples for COD or BOD5 concentration at least once each 
calendar week that the anaerobic wastewater treatment process is 
operating; if only one measurement is made each calendar week, there 
must be at least three days between measurements. You must collect a 
sample that represents the average COD or BOD5 concentration 
of the waste stream over a 24-hour sampling period. You must collect a 
minimum of four sample aliquots per 24-hour period and composite the 
aliquots for analysis. Collect a flow-proportional composite sample 
(either constant time interval between samples with sample volume 
proportional to stream flow, or constant sample volume with time 
interval between samples proportional to stream flow). Follow sampling 
procedures and techniques presented in Chapter 5, Sampling, of the 
``NPDES Compliance Inspection Manual,'' (incorporated by reference, see 
Sec. 98.7) or Section 7.1.3, Sample Collection Methods, of the ``U.S. 
EPA NPDES Permit Writers' Manual,'' (incorporated by reference, see 
Sec. 98.7).
    (d) You must measure the flowrate of wastewater entering anaerobic 
wastewater treatment process at least once each calendar week that the

Sec. 98.355  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions during unit operation or if a required sample is not 
taken), a substitute data value for the missing parameter must be used 
in the calculations, according to the following requirements in 
paragraphs (a) through (c) of this section:
    (a) For each missing weekly value of COD or BOD5 or 
wastewater flow entering an anaerobic wastewater treatment process, the 
substitute data value must be the arithmetic average of the quality-
assured values of those parameters for the week immediately preceding 
and the week immediately following the missing data incident.
    (b) For each missing value of the CH4 content or biogas 
flow rates, the substitute data value must be the arithmetic average of 
the quality-assured values of that parameter immediately preceding and 
immediately following the missing data incident.
    (c) If, for a particular parameter, no quality-assured data are 
available prior to the missing data incident, the substitute data value 
must be the first quality-assured value obtained after the missing data 
period. If, for a particular parameter, the ``after'' value is not 
obtained by the end of the reporting year, you may use the last quality-
assured value obtained ``before'' the missing data period for the 
missing data substitution. You must document and keep records of the 
procedures you use for all such estimates.

                      Subpart JJ_Manure Management



Sec. 98.360  Definition of the source category.

    (a) This source category consists of livestock facilities with 
manure management systems that emit 25,000 metric tons CO2e 
or more per year.
    (1) Table JJ-1 presents the minimum average annual animal population 
by animal group that is estimated to emit 25,000 metric tons 
CO2e or more per year. Facilities with an average annual 
animal population, as described in Sec. 98.363(a)(1) and (2), below 
those listed in Table JJ-1 do not need to report under this rule. A 
facility with an annual animal population that exceeds those listed in 
Table JJ-1 should conduct a more thorough analysis to determine 
applicability.
    (2) (i) If a facility has more than one animal group present (e.g., 
swine and poultry), the facility must determine if they are required to 
report by calculating the combined animal group factor (CAGF) using 
equation JJ-1:

[[Page 1020]]

[GRAPHIC] [TIFF OMITTED] TR30OC09.137

Where:

CAGF = Combined Animal Group Factor
AAAPAG,Facility = Average annual animal population at the 
          facility, by animal group
APTL AG = Animal population threshold level, as specified in 
          Table JJ-1 of this section

    (ii) If the calculated CAGF for a facility is less than 1, the 
facility is not required to report under this rule. If the CAGF is equal 
to or greater than 1, the facility must use more detailed applicability 
tables and tools to determine if they are required to report under this 
rule.
    (b) A manure management system (MMS) is a system that stabilizes 
and/or stores livestock manure, litter, or manure wastewater in one or 
more of the following system components: Uncovered anaerobic lagoons, 
liquid/slurry systems with and without crust covers (including but not 
limited to ponds and tanks), storage pits, digesters, solid manure 
storage, dry lots (including feedlots), high-rise houses for poultry 
production (poultry without litter), poultry production with litter, 
deep bedding systems for cattle and swine, manure composting, and 
aerobic treatment.
    (c) This source category does not include system components at a 
livestock facility that are unrelated to the stabilization and/or 
storage of manure such as daily spread or pasture/range/paddock systems 
or land application activities or any method of manure utilization that 
is not listed in Sec. 98.360(b).
    (d) This source category does not include manure management 
activities located off site from a livestock facility or off-site manure 
composting operations.

    Livestock facilities must report GHG emissions under this subpart if 
the facility meets the reporting threshold as defined in 98.360(a) 
above, contains a manure management system as defined in 98.360(b) 
above, and meets the requirements of Sec. 98.2(a)(1).



Sec. 98.362  GHGs to report.

    (a) Livestock facilities must report annual aggregate CH4 
and N2O emissions for the following MMS components at the 
facility:

    (2) Liquid/slurry systems (with and without crust covers, and 
including but not limited to ponds and tanks).
    (3) Storage pits.
    (4) Digesters, including covered anaerobic lagoons.
    (5) Solid manure storage.
    (6) Dry lots, including feedlots.
    (7) High-rise houses for poultry production (poultry without litter)
    (8) Poultry production with litter.
    (9) Deep bedding systems for cattle and swine.
    (10) Manure composting.
    (11) Aerobic treatment.
    (b) A livestock facility that is subject to this rule only because 
of emissions from manure management system components is not required to 
report emissions from subparts C through PP (other than subpart JJ) of 
this part.
    (c) A livestock facility that is subject to this part because of 
emissions from source categories described in subparts C through PP of 
this part is not required to report emissions under subpart JJ of this 
part unless emissions from manure management systems are 25,000 metric 
tons CO2e per year or more.

\1\ The threshold head populations in this table were calculated using
  the most conservative assumptions (high VS and N values, maximum
  ambient temperatures, and the application of an uncertainty factor) to
  ensure that facilities at or near the 25,000 metric ton CO2e threshold
  level were not excluded from reporting.
\2\ For facilities with more than one animal group present refer to Sec.
    98.360 (2) to estimate the combined animal group factor (CAGF),
  which is used to determine if a facility may be required to report.
\3\ For all animal groups except dairy, the average annual animal
  population represents the total number of animals present at the
  facility. For dairy facilities, the average annual animal population
  represents the number of mature dairy cows present at the facility
  (note that heifers and calves were included in the emission estimates
  for dairy facilities using the assumption that the average annual
  animal population of heifers and calves at dairy facilities are equal
  to 30 percent of the mature dairy cow average annual animal
  population, therefore the average annual population for dairy
  facilities should not include heifers and calves, only dairy cows).

Sec. 98.394  Monitoring and QA/QC requirements.

    (a) Determination of quantity. (1) The quantity of petroleum 
products, natural gas liquids, and biomass, shall be determined as 
follows:
    (i) Where an appropriate standard method published by a consensus-
based standards organization exists, such a method shall be used. 
Consensus-based standards organizations include, but are not limited to, 
the following: ASTM International, the American National Standards 
Institute (ANSI), the American Gas Association (AGA), the American 
Society of Mechanical Engineers (ASME), the American Petroleum Institute 
(API), and the North American Energy Standards Board (NAESB).
    (ii) Where no appropriate standard method developed by a consensus-
based standards organization exists, industry standard practices shall 
be followed.
    (iii) For products that are liquid at 60 degrees Fahrenheit and one 
standard atmosphere, all measurements of quantity shall be temperature-
adjusted and pressure-adjusted to these conditions. For all other 
products, reporters shall use appropriate standard conditions specified 
in the standard method; if temperature and pressure conditions are not 
specified in the standard method or if a reporter uses an industry 
standard practice to determine quantity, the reporter shall use 
appropriate standard conditions according to established industry 
practices.
    (2) All measurement equipment (including, but not limited to, flow 
meters and tank gauges) used for compliance with this subpart shall be 
appropriate for the standard method or industry standard practice 
followed under paragraph (a)(1)(i) or (a)(1)(ii) of this section.
    (3) The annual quantity of crude oil received shall be determined 
according to one of the following methods. You may use an appropriate 
standard method published by a consensus-based standards organization or 
you may use an industry standard practice.
    (b) Equipment Calibration. (1) All measurement equipment shall be 
calibrated prior to its first use for reporting under this subpart, 
using an appropriate standard method published by a consensus based 
standards organization or according to the equipment manufacturer's 
directions.
    (2) Measurement equipment shall be recalibrated at the minimum 
frequency specified by the standard method used or by the equipment 
manufacturer's directions.
    (3) For units and processes that operate continuously with 
infrequent outages, it may not be possible to complete the calibration 
of a flow meter or other measurement device without disrupting normal 
process operation. In such cases, the owner or operator may

[[Page 1040]]

postpone the calibration until the next scheduled maintenance outage. 
The best available information from company records may be used in the 
interim. Such postponements shall be documented in the monitoring plan 
that is required under Sec. 98.3(g)(5).
    (c) Procedures for Calculation Method 2 of this subpart. (1) 
Reporting parties shall collect one sample of each petroleum product or 
natural gas liquid on any day of each calendar month of the reporting 
year in which the quantity of that product was measured in accordance 
with the requirements of this subpart. For example, if a given product 
was measured as entering the refinery continuously throughout the 
reporting year, twelve samples of that product shall be collected over 
the reporting year, one on any day of each calendar month of that year. 
If a given product was only measured from April 15 through June 10 of 
the reporting year, a refiner would collect three samples during that 
year, one during each of the calendar months of April, May and June on a 
day when the product was measured as either entering or exiting the 
refinery. Each sample shall be collected using an appropriate standard 
method published by a consensus-based standards organization.
    (2) Mixing and handling of samples shall be performed using an 
appropriate standard method published by a consensus-based standards 
organization.
    (3) Density measurement.
    (i) For all products that are not solid, reporters shall test for 
density using an appropriate standard method published by a consensus-
based standards organization.
    (ii) The density value for a given petroleum product shall be 
generated by either making a physical composite of all of the samples 
collected for the reporting year and testing that single sample or by 
measuring the individual samples throughout the year and defining the 
representative density value for the sample set by numerical means, 
i.e., a mathematical composite. If a physical composite is chosen as the 
option to obtain the density value, the reporter shall submit each of 
the individual samples collected during the reporting year to the 
laboratory responsible for generating the composite sample.
    (iii) For physical composites, the reporter shall handle the 
individual samples and the laboratory shall mix them in accordance with 
an appropriate standard method published by a consensus-based standards 
organization.
    (iv) All measurements of density shall be temperature-adjusted and 
pressure-adjusted to the conditions assumed for determining the 
quantities of the product reported under this subpart.
    (4) Carbon share measurement.
    (i) Reporters shall test for carbon share using an appropriate 
standard method published by a consensus-based standards organization.
    (ii) If a standard method that involves gas chromatography is used 
to determine the percent mass of each component in a product, the 
molecular formula for each component shall be obtained from the 
information provided in the standard method and the atomic mass of each 
element in a given molecular component shall be obtained from the 
periodic table of the elements.
    (iii) The carbon share value for a given petroleum product shall be 
generated by either making a physical composite of all of the samples 
collected for the reporting year and testing that single sample or by 
measuring the individual samples throughout the year and defining the 
representative carbon share value for the sample set by numerical means, 
i.e., a mathematical composite. If a physical composite is chosen as the 
option to obtain the carbon share value, the reporter shall submit each 
of the individual samples collected during the reporting year to the 
laboratory responsible for generating the composite sample.
    (iv) For physical composites, the reporter shall handle the 
individual samples and the laboratory shall mix them in accordance with 
an appropriate standard method published by a consensus-based standards 
organization.

Sec. 98.395  Procedures for estimating missing data.

    (a) Determination of quantity. Whenever the quality assurance 
procedures in Sec. 98.394(a) cannot be followed to measure the quantity 
of one or more petroleum products, natural gas liquids, types of 
biomass, feedstocks, or crude oil during any period (e.g., if a meter 
malfunctions), the following missing data procedures shall be used:
    (1) For quantities of a product that are purchased or sold, a period 
of missing data shall be substituted using a reporter's established 
procedures for billing purposes in that period as agreed to by the party 
selling or purchasing the product.
    (2) For quantities of a product that are not purchased or sold but 
of which the custody is transferred, a period of missing data shall be 
substituted using a reporter's established procedures for tracking 
purposes in that period as agreed to by the party involved in custody 
transfer of the product.
    (b) Determination of emission factor. Whenever any of the procedures 
in Sec. 98.394(c) cannot be followed to develop an emission factor for 
any reason, Calculation Method 1 of this subpart must be used in place 
of Calculation Method 2 of this subpart for the entire reporting year.

       Subpart NN_Suppliers of Natural Gas and Natural Gas Liquids



Sec. 98.400  Definition of the source category.

    This supplier category consists of natural gas liquids fractionators 
and local natural gas distribution companies.
    (a) Natural gas liquids fractionators are installations that 
fractionate natural gas liquids (NGLs) into their constituent liquid 
products or mixtures of products (ethane, propane, normal butane, 
isobutane or pentanes plus) for supply to downstream facilities.
    (b) Local Distribution Companies (LDCs) are companies that own or 
operate distribution pipelines, not interstate pipelines or intrastate 
pipelines, that physically deliver natural gas to end users and that are 
within a single state that are regulated as separate operating companies 
by State public utility commissions or that operate as independent 
municipally-owned distribution systems. LDCs do not include pipelines 
(both interstate and intrastate) delivering natural gas directly to 
major industrial users and farm taps upstream of the local distribution 
company inlet.
    (c) This supply category does not consist of the following 
facilities:
    (1) Field gathering and boosting stations.
    (2) Natural gas processing plants that separate NGLs from natural 
gas and produce bulk or y-grade NGLs but do not fractionate these NGLs 
into their constituent products.
    (3) Facilities that meet the definition of refineries and report 
under subpart MM of this part.
    (4) Facilities that meet the definition of petrochemical plants and 
report under subpart X of this part.

[74 FR 56374, Oct. 30, 2009, as amended at 78 FR 71975, Nov. 29, 2013]



Sec. 98.401  Reporting threshold.

    Any supplier of natural gas and natural gas liquids that meets the 
requirements of Sec. 98.2(a)(4) must report GHG emissions associated 
with the products they supply.

[81 FR 89268, Dec. 9, 2016]



Sec. 98.402  GHGs to report.

    (a) NGL fractionators must report the CO2 emissions that 
would result from the complete combustion or oxidation of the annual 
quantity of ethane, propane, normal butane, isobutane, and pentanes plus 
that is produced and sold or delivered to others.
    (b) LDCs must report the CO2 emissions that would result 
from the complete combustion or oxidation of the annual volumes of 
natural gas provided to end-users on their distribution systems.



Sec. 98.403  Calculating GHG emissions.

    (a) LDCs and fractionators shall, for each individual product 
reported under this part, calculate the estimated CO2

[[Page 1047]]

emissions that would result from the complete combustion or oxidation of 
the products supplied using either of Calculation Methodology 1 or 2 of 
this subpart:
    (1) Calculation Methodology 1. NGL fractionators shall estimate 
CO2 emissions that would result from the complete combustion 
or oxidation of the product(s) supplied using Equation NN-1 of this 
section. The annual volume of each NGL product supplied 
(Fuelh) shall include any amount of that NGL supplied in a 
mixture or blend of two or more products listed in Tables NN-1 and NN-2 
of this subpart. The annual volume of each NGL product supplied shall 
exclude any amount of that NGL contained in bulk NGLs exiting the 
facility (e.g., y-grade, o-grade, and other bulk NGLs). LDCs shall 
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 
must use the same volume unit throughout the equation.
[GRAPHIC] [TIFF OMITTED] TR30OC09.163

Where:

CO2i = Annual CO2 mass emissions that would result 
          from the combustion or oxidation of each product ``h'' for 
          redelivery to all recipients (metric tons).
Fuelh = Total annual volume of product ``h'' supplied (volume 
          per year, in thousand standard cubic feet (Mscf) for natural 
          gas and bbl for NGLs).
HHVh = Higher heating value of product ``h'' supplied (MMBtu/
          Mscf or MMBtu/bbl).
EFh = CO2 emission factor of product ``h'' (kg 
          CO2/MMBtu).
1 x 10-3 = Conversion factor from kilograms to metric tons 
          (MT/kg).

    (2) Calculation Methodology 2. NGL fractionators shall estimate 
CO2 emissions that would result from the complete combustion 
or oxidation of the product(s) supplied using Equation NN-2 of this 
section. The annual volume of each NGL product supplied 
(Fuelh) shall include any amount of that NGL supplied in a 
mixture or blend of two or more products listed in Tables NN-1 and NN-2 
of this subpart. The annual volume of each NGL product supplied shall 
exclude any amount of that NGL contained in bulk NGLs exiting the 
facility (e.g., y-grade, o-grade, and other bulk NGLs). LDCs shall 
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-2 of this section. For each product, use the 
default CO2 emission factor found in Table NN-2 of this 
subpart. Alternatively, for each product, a reporter-specific 
CO2 emission factor may be used in place of the default 
factor, provided it is developed using methods outlined in Sec. 98.404. 
For each product, you must use the same volume unit throughout the 
equation.
[GRAPHIC] [TIFF OMITTED] TR30OC09.164

Where:

CO2i = Annual CO2 mass emissions that would result 
          from the combustion or oxidation of each product ``h'' (metric 
          tons)
Fuelh = Total annual volume of product ``h'' supplied (volume 
          per year, in Mscf for natural gas and bbl for NGLs).
EFh = CO2 emission factor of product ``h'' (MT 
          CO2/bbl, or MT CO2/Mscf)

    (b) Each LDC shall follow the procedures below.
    (1) For natural gas that is received for redelivery to downstream 
gas transmission pipelines and other local distribution companies, use 
Equation NN-3 of this section and the default values for the 
CO2 emission factors found in

[[Page 1048]]

Table NN-2 of this subpart. Alternatively, reporter-specific 
CO2 emission factors may be used, provided they are developed 
using methods outlined in Sec. 98.404.
[GRAPHIC] [TIFF OMITTED] TR30OC09.165

Where:

CO2j = Annual CO2 mass emissions that would result 
          from the combustion or oxidation of natural gas for redelivery 
          to transmission pipelines or other LDCs (metric tons).
Fuel = Total annual volume of natural gas supplied to downstream gas 
          transmission pipelines and other local distribution companies 
          (Mscf per year).
EF = Fuel-specific CO2 emission factor (MT CO2/
          Mscf).

    (2)(i) For natural gas delivered to large end-users, use Equation 
NN-4 of this section and the default values for the CO2 
emission factors found in Table NN-2 of this subpart. A large end-user 
means any end-user facility receiving greater than or equal to 460,000 
Mscf of natural gas per year. If the LDC does not know the total 
quantity of gas delivered to the end-user facility based on readily 
available information in the LDCs possession, then large end-user means 
any single meter at an end-user facility to which the LDC delivers equal 
to or greater than 460,000 Mscf per year.
    (ii) Alternatively, reporter-specific CO2 emission 
factors may be used, provided they are developed using methods outlined 
in Sec. 98.404.
[GRAPHIC] [TIFF OMITTED] TR30OC09.166

Where:

CO2k = Annual CO2 mass emissions that would result 
          from the combustion or oxidation of natural gas delivered to 
          each large end-user k, as defined in paragraph (b)(2)(i) of 
          this section (metric tons).
Fuel = Total annual volume of natural gas supplied to each large end-
          user k, as defined in paragraph (b)(2)(i) of this section 
          (Mscf per year).
EF = Fuel-specific CO2 emission factor (MT CO2/
          Mscf).

    (3) For the net change in natural gas stored on system by the LDC 
during the reporting year, use Equation NN-5a of this section. For 
natural gas that is received by means other than through the city gate, 
and is not otherwise accounted for by Equation NN-1 or NN-2 of this 
section, use Equation NN-5b of this section.
    (i) For natural gas received by the LDC that is injected into on-
system storage, and/or liquefied and stored, and for gas removed from 
storage and used for deliveries, use Equation NN-5a of this section and 
the default value for the CO2 emission factors found in Table 
NN-2 of this subpart. Alternatively, a reporter-specific CO2 
emission factor may be used, provided it is developed using methods 
outlined in Sec. 98.404.
[GRAPHIC] [TIFF OMITTED] TR29NO13.028

Where:

CO2l = Annual CO2 mass emissions that would result

shall be the measurements taken at custody transfers summed to the 
annual reportable volume.
    (ii) For natural gas the minimum frequency of measurement shall be 
based on the LDC's standard measurement schedules used for billing 
purposes and summed to the annual reportable volume.
    (3) NGL fractionators shall use measurement for NGLs at custody

Sec. 98.405  Procedures for estimating missing data.

    (a) Whenever a quality-assured value of the quantity of natural gas 
liquids or natural gas supplied during any period is unavailable (e.g., 
if a flow meter malfunctions), a substitute data value for the missing 
quantity measurement must be used in the calculations according to 
paragraphs (b) and (c) of this section.
    (b) Determination of quantity. (1) NGL fractionators shall 
substitute meter records provided by pipeline(s) for all pipeline 
receipts of NGLs; by manifests for deliveries made to trucks or rail 
cars; or metered quantities accepted by the entities purchasing the 
output from the fractionator whether by pipeline or by truck or rail 
car. In cases where the metered data from the receiving pipeline(s) or 
purchasing entities are not available, fractionators may substitute 
estimates based on contract quantities required to be delivered under 
purchase or delivery contracts with other parties.

[[Page 1052]]

    (2) LDCs shall either substitute their delivering pipeline metered 
deliveries at the city gate or substitute nominations and scheduled 
delivery quantities for the period when metered values of actual 
deliveries are not available.
    (c) Determination of HHV and EF. (1) Whenever an LDC that makes its 
own HHV measurements according to established business practices cannot 
follow the quality assurance procedures for developing a reporter-
specific HHV, as specified in Sec. 98.404, during any period for any 
reason, the reporter shall use either its delivering pipeline 
measurements or the default HHV provided in Table NN-1 of this part for 
that period.
    (2) Whenever an LDC that does not make its own HHV measurements 
according to established business practices or an NGL fractionator 
cannot follow the quality assurance procedures for developing a 
reporter-specific HHV, as specified in Sec. 98.404, during any period 
for any reason, the reporter shall use the default HHV provided in Table 
NN-1 of this part for that period.
    (3) [Reserved]
    (4) Whenever a reporter cannot follow the quality assurance 
procedures for developing a reporter-specific EF, as specified in Sec. 
98.404, during any period for any reason, the reporter shall use the 
default EF provided in Sec. 98.408 for that period.

Sec. 98.410  Definition of the source category.

    (a) The industrial gas supplier source category consists of any 
facility that produces fluorinated GHGs or nitrous oxide; any bulk 
importer of fluorinated GHGs or nitrous oxide; and any bulk exporter of 
fluorinated GHGs or nitrous oxide. Starting with reporting year 2018, 
this source category also consists of any facility that produces 
fluorinated HTFs; any bulk importer of fluorinated HTFs; any bulk 
exporter of fluorinated HTFs; and any facility that destroys fluorinated 
GHGs or fluorinated HTFs.
    (b) To produce a fluorinated GHG means to manufacture a fluorinated 
GHG from any raw material or feedstock chemical. Producing a fluorinated 
GHG includes the manufacture of a fluorinated GHG as an isolated 
intermediate for use in a process that will result in its transformation 
either at or outside of the production facility. Producing a fluorinated 
GHG also includes the creation of a fluorinated GHG (with the exception 
of HFC-23) that is captured and shipped off site for any reason, 
including destruction. Producing a fluorinated GHG does not include the 
reuse or recycling of a fluorinated GHG, the creation of HFC-23 during 
the production of HCFC-22, the creation of intermediates that are 
created and transformed in a single process with no storage of the 
intermediates, or the creation of fluorinated GHGs that are released or 
destroyed at the production facility before the production measurement 
at Sec. 98.414(a).
    (c) To produce nitrous oxide means to produce nitrous oxide by 
thermally decomposing ammonium nitrate (NH4NO3). 
Producing nitrous oxide does

[[Page 1055]]

not include the reuse or recycling of nitrous oxide or the creation of 
by-products that are released or destroyed at the production facility.
    (d) To produce a fluorinated HTF means to manufacture, from any raw 
material or feedstock chemical, a fluorinated GHG used for temperature 
control, device testing, cleaning substrate surfaces and other parts, 
and soldering in processes including but not limited to certain types of 
electronics manufacturing production processes. Fluorinated heat 
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.

Sec. 98.411  Reporting threshold.

    Any supplier of industrial greenhouse gases who meets the 
requirements of Sec. 98.2(a)(4) must report GHG emissions.



Sec. 98.412  GHGs to report.

    You must report the GHG emissions that would result from the release 
of the nitrous oxide and each fluorinated GHG that you produce, import, 
export, transform, or destroy during the calendar year. Starting with 
reporting year 2018, you must also report the emissions that would 
result from the release of each fluorinated HTF that is not also a 
fluorinated GHG and that you produce, import, export, transform, or 
destroy during the calendar year.

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

[[Page 1057]]

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.
    (j) [Reserved]
    (k) For purposes of Equation OO-4 of this subpart, the destruction 
efficiency can be equated to the destruction efficiency determined 
during a previous performance test of the destruction device or, if no 
performance test has been done, the destruction efficiency provided by 
the manufacturer of the destruction device.
    (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.
    (m) Calibrate all flow meters, weigh scales, and combinations of 
volumetric and density measures that are used to measure or calculate 
quantities that are to be reported under this subpart prior to the first 
year for which GHG emissions are reported under this part. Calibrations 
performed prior to the effective date of this rule satisfy this 
requirement. Recalibrate all flow meters, weigh scales, and combinations 
of volumetric and density measures at the minimum frequency specified by 
the manufacturer. Use NIST-traceable standards and suitable methods 
published by a consensus standards organization (e.g., ASTM, ASME, ISO, 
or others).
    (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:
    (1) Analytical Methods. Use a quality-assured analytical measurement 
technology capable of detecting the analyte of interest at the 
concentration of interest and use a procedure validated with the analyte 
of interest at the concentration of interest. Where standards for the 
analyte are not available, a

[[Page 1058]]

chemically similar surrogate may be used. Acceptable analytical 
measurement technologies include but are not limited to gas 
chromatography (GC) with an appropriate detector, infrared (IR), fourier 
transform infrared (FTIR), and nuclear magnetic resonance (NMR). 
Acceptable methods include EPA Method 18 in appendix A-1 of 40 CFR part 
60; EPA Method 320 in appendix A of 40 CFR part 63; the Protocol for 
Measuring Destruction or Removal Efficiency (DRE) of Fluorinated 
Greenhouse Gas Abatement Equipment in Electronics Manufacturing, Version 
1, EPA-430-R-10-003, (March 2010) (incorporated by reference, see Sec. 
98.7); ASTM D6348-03 Standard Test Method for Determination of Gaseous 
Compounds by Extractive Direct Interface Fourier Transform Infrared 
(FTIR) Spectroscopy (incorporated by reference, see Sec. 98.7); or 
other analytical methods validated using EPA Method 301 in appendix A of 
40 CFR part 63 or some other scientifically sound validation protocol. 
The validation protocol may include analytical technology manufacturer 
specifications or recommendations.
    (2) Documentation in GHG Monitoring Plan. Describe the analytical 
method(s) used under paragraph (n)(1) of this section in the site GHG 
Monitoring Plan as required under Sec. 98.3(g)(5). At a minimum, 
include in the description of the method a description of the analytical 
measurement equipment and procedures, quantitative estimates of the 
method's accuracy and precision for the analytes of interest at the 
concentrations of interest, as well as a description of how these 
accuracies and precisions were estimated, including the validation 
protocol used.
    (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.
    (p) Isolated intermediates that are produced and transformed at the 
same

[[Page 1059]]

facility are exempt from the monitoring requirements of this section.
    (q) Low-concentration constituents are exempt from the monitoring 
and QA/QC requirements of this section.

81 FR 89270, Dec. 9, 2016]



Sec. 98.415  Procedures for estimating missing data.

    (a) A complete record of all measured parameters used in the GHG 
emissions calculations is required. Therefore, whenever a quality-
assured value of a required parameter is unavailable (e.g., if a meter 
malfunctions), a substitute data value for the missing parameter shall 
be used in the calculations, according to paragraph (b) of this section.
    (b) For each missing value of the mass produced, fed into the 
production process (for used material being reclaimed), 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.

are returned to the facility for reclamation but are found to be 
irretrievably contaminated and are therefore sent to another facility 
for destruction.

Sec. 98.418  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.
    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.
    Low-concentration constituent means, for purposes of fluorinated GHG 
or fluorinated HTF production and export, a fluorinated GHG or 
fluorinated HTF constituent of a fluorinated GHG or fluorinated HTF 
product that occurs in the product in concentrations below 0.1 percent 
by mass. For purposes of fluorinated GHG or fluorinated HTF import, low-
concentration constituent means a fluorinated GHG or fluorinated HTF 
constituent of a fluorinated GHG or fluorinated HTF product that occurs 
in the product in concentrations below 0.5 percent by mass. Low-
concentration constituents do not include fluorinated GHGs or 
fluorinated HTFs that are deliberately combined with the product (e.g., 
to affect the performance characteristics of the product).

CO2

[[Page 1082]]

produced from oil or other fluid production wells is a flow meter 
directly downstream of each separator that sends a stream of gas into a

Sec. 98.448  Geologic sequestration monitoring, reporting,
and verification (MRV) plan.

    (a) Contents of MRV plan. You must develop and submit to the 
Administrator a proposed MRV plan for monitoring, reporting, and 
verification of geologic sequestration at your facility. Your proposed 
MRV plan must contain the following components:
    (1) Delineation of the maximum monitoring area and the active 
monitoring areas. The first period for your active monitoring area will 
begin from the date determined in your MRV plan through the date at 
which the plan calls for the first expansion of the monitoring area. The 
length of each monitoring period can be any time interval chosen by you 
that is greater than 1 year.
    (2) Identification of potential surface leakage pathways for 
CO2 in the maximum monitoring area and the likelihood, 
magnitude, and timing, of surface leakage of CO2 through 
these pathways.
    (3) A strategy for detecting and quantifying any surface leakage of 
CO2.
    (4) A strategy for establishing the expected baselines for 
monitoring CO2 surface leakage.
    (5) A summary of the considerations you intend to use to calculate 
site-specific variables for the mass balance equation. This includes, 
but is not limited to, considerations for calculating CO2 
emissions from equipment leaks and vented emissions of CO2 
between the injection flow meter and injection well and/or the 
production flow meter and production well, and considerations for 
calculating CO2 in produced fluids.
    (6) If a well is permitted under the Underground Injection Control 
program, for each injection well, report the well identification number 
used for the Underground Injection Control permit and the Underground 
Injection Control permit class. If the well is not yet permitted, and 
you have applied for an Underground Injection Control permit, report the 
well identification numbers in the permit application. If an offshore 
well is not subject to the Safe Drinking Water Act, for each injection 
well, report any well identification number and any identification 
number used for the legal instrument authorizing geologic sequestration. 
If you are submitting your Underground Injection Control permit 
application as part of your proposed MRV plan, you must notify EPA when 
the permit has been approved. If you are an offshore facility not 
subject to the Safe Drinking Water Act, and are submitting your 
application for the legal instrument authorizing geologic sequestration 
as part of your proposed MRV plan, you must notify EPA when the legal 
instrument authorizing geologic sequestration has been approved.
    (7) Proposed date to begin collecting data for calculating total 
amount sequestered according to equation RR-11 or RR-12 of this subpart. 
This date must be after expected baselines as required by paragraph 
(a)(4) of this section are established and the leakage detection and 
quantification strategy as required by paragraph (a)(3) of this section 
is implemented in the initial AMA.
    (b) Timing. You must submit a proposed MRV plan to EPA according to 
the following schedule:
    (1) You must submit a proposed MRV plan to EPA by June 30, 2011 if 
you were issued a final Underground Injection Control permit authorizing 
the injection of CO2 into the subsurface on or before 
December 31, 2010. You will be allowed to request one extension of up to 
an additional 180 days in which to submit your proposed MRV plan.
    (2) You must submit a proposed MRV plan to EPA within 180 days of 
receiving a final Underground Injection Control permit authorizing the 
injection of CO2 into the subsurface. If your facility is an 
offshore facility not subject to the Safe Drinking Water Act, you must 
submit a proposed MRV plan to EPA

[[Page 1087]]

within 180 days of receiving authorization to begin geologic 
sequestration of CO2. You will be allowed to request one 
extension of the submittal date of up to an additional 180 days.
    (3) If you are injecting a CO2 stream in subsurface 
geologic formations to enhance the recovery of oil or natural gas and 
you are not permitted as Class VI under the Underground Injection 
Control program, you may opt to submit an MRV plan at any time.
    (4) If EPA determines that your proposed MRV plan is incomplete, you 
must submit an updated MRV plan within 45 days of EPA notification, 
unless otherwise specified by EPA.
    (c) Final MRV plan. The Administrator will issue a final MRV plan 
within a reasonable period of time. The Administrator's final MRV plan 
is subject to the provisions of part 78 of this chapter. Once the MRV 
plan is final and no longer subject to administrative appeal under part 
78 of this chapter, you must implement the plan starting on the day 
after the day on which the plan becomes final and is no longer subject 
to such appeal.
    (d) MRV plan revisions. You must revise and submit the MRV plan 
within 180 days to the Administrator for approval if any of the 
following in paragraphs (d)(1) through (d)(4) of this section applies. 
You must include the reason(s) for the revisions in your submittal.
    (1) A material change was made to monitoring and/or operational 
parameters that was not anticipated in the original MRV plan. Examples 
of material changes include but are not limited to: Large changes in the 
volume of CO2 injected; the construction of new injection 
wells not identified in the MRV plan; failures of the monitoring system 
including monitoring system sensitivity, performance, location, or 
baseline; changes to surface land use that affects baseline or 
operational conditions; observed plume location that differs 
significantly from the predicted plume area used for developing the MRV 
plan; a change in the maximum monitoring area or active monitoring area; 
or a change in monitoring technology that would result in coverage or 
detection capability different from the MRV plan.
    (2) A change in the permit class of your Underground Injection 
Control permit.
    (3) If you are notified by EPA of substantive errors in your MRV 
plan or monitoring report.
    (4) You choose to revise your MRV plan for any other reason in any 
reporting year.
    (e) Revised MRV plan. The requirements of paragraph (c) of this 
section apply to any submission of a revised MRV plan. You must continue 
reporting under your currently approved plan while awaiting approval of 
a revised MRV plan.
    (f) Format. Each proposed MRV plan or revision and each annual 
report must be submitted electronically in a format specified by the 
Administrator.
    (g) Certificate of representation. You must submit a certificate of 
representation according to the provisions in Sec. 98.4 at least 60 
days before submission of your MRV plan, your research and development 
exemption request, your MRV plan submission extension request, or your 
initial annual report under this part, whichever is earlier.

generally used to weigh cylinders containing 115 pounds of gas when 
full, this equates to 1 percent of the sum of 115 
pounds and approximately 120 pounds tare, or slightly more than 2 pounds. Account for the tare weights of the 
containers. You may accept gas masses or weights provided by the gas 
supplier e.g., for the contents of cylinders containing new gas or for 
the heels remaining in cylinders returned to the gas supplier) if the 
supplier provides documentation verifying that accuracy standards are 
met; however, you remain responsible for the accuracy of these masses 
and weights under this subpart.
    (c) All flow meters, weigh scales, and combinations of volumetric 
and density measures that are used to measure or calculate quantities 
under this subpart must be calibrated using calibration procedures 
specified by the flowmeter, scale, volumetric or density measure 
equipment manufacturer. Calibration must be performed prior to the first 
reporting year. After the initial calibration, recalibration must be 
performed at the minimum frequency specified by the manufacturer.
    (d) For purposes of Equations SS-5 of this subpart, the emission 
factor for the valve-hose combination (EFC) must be estimated 
using measurements and/or engineering assessments or calculations based 
on chemical engineering principles or physical or chemical laws or 
properties. Such assessments or calculations may be based on, as 
applicable, the internal volume of hose or line that is open to the 
atmosphere during coupling and decoupling activities, the internal 
pressure of the hose or line, the time the hose or line is open to the 
atmosphere during coupling and decoupling activities, the frequency with 
which the hose or line is purged and the flow rate during purges. You 
must develop a value for EFc (or use an industry-developed 
value) for each combination of hose and valve fitting, to use in 
Equation SS-5 of this subpart. The value for EFC must be 
determined for each combination of hose and valve fitting of a given 
diameter or size. The calculation must be recalculated annually to 
account for changes to the specifications of the valves or hoses that 
may occur throughout the year.
    (e) Electrical equipment manufacturers and refurbishers must account 
for SF6 or PFC emissions that occur as a result of unexpected 
events or accidental losses, such as a malfunctioning hose or leak in 
the flow line, during the filling of equipment or containers for 
disbursement by including these losses in the estimated mass of 
SF6 or the

[[Page 1092]]

PFC emitted downstream of the container or flowmeter during the period 
p.
    (f) If the mass of SF6 or the PFC disbursed to customers 
in new equipment over the period p is determined by assuming that it is 
equal to the equipment's nameplate capacity or, in cases where equipment 
is shipped with a partial charge, equal to its partial shipping charge, 
equipment samples for conducting the nameplate capacity tests must be 
selected using the following stratified sampling strategy in this 
paragraph. For each make and model, group the measurement conditions to 
reflect predictable variability in the facility's filling practices and 
conditions (e.g., temperatures at which equipment is filled). Then, 
independently select equipment samples at random from each make and 
model under each group of conditions. To account for variability, a 
certain number of these measurements must be performed to develop a 
robust and representative average nameplate capacity (or shipping 
charge) for each make, model, and group of conditions. A Student T 
distribution calculation should be conducted to determine how many 
samples are needed for each make, model, and group of conditions as a 
function of the relative standard deviation of the sample measurements. 
To determine a sufficiently precise estimate of the nameplate capacity, 
the number of measurements required must be calculated to achieve a 
precision of one percent of the true mean, using a 95 percent confidence 
interval. To estimate the nameplate capacity for a given make and model, 
you must use the lowest mean value among the different groups of 
conditions, or provide justification for the use of a different mean 
value for the group of conditions that represents the typical practices 
and conditions for that make and model. Measurements can be conducted 
using SF6, another gas, or a liquid. Re-measurement of 
nameplate capacities should be conducted every five years to reflect 
cumulative changes in manufacturing methods and conditions over time.
    (g) Ensure the following QA/QC methods are employed throughout the 
year:
    (1) Procedures are in place and followed to track and weigh all 
cylinders or other containers at the beginning and end of the year.
    (h) You must adhere to the following QA/QC methods for reviewing the 
completeness and accuracy of reporting:
    (1) Review inputs to Equation SS-1 of this subpart to ensure inputs 
and outputs to the company's system are included.
    (2) Do not enter negative inputs and confirm that negative emissions 
are not calculated. However, the decrease in SF6 inventory 
may be calculated as negative.
    (3) Ensure that beginning-of-year inventory matches end-of-year 
inventory from the previous year.
    (4) Ensure that in addition to SF6 purchased from bulk 
gas distributors, SF6 returned from equipment users with or 
inside equipment and SF6 returned from off-site recycling are 
also accounted for among the total additions.



Sec. 98.455  Procedures for estimating missing data.

    A complete record of all measured parameters used in the GHG 
emissions calculations is required. Replace missing data, if needed, 
based on data from similar manufacturing operations, and from similar 
equipment testing and decommissioning activities for which data are

77 FR 51495, Aug. 24, 2012; 78 FR 71979, Nov. 29, 2013]



Sec. 98.461  Reporting threshold.

    You must report GHG emissions under this subpart if your facility 
contains an industrial waste landfill meeting the criteria in Sec. 
98.460 and the facility meets the requirements of Sec. 98.2(a)(2). For 
the purposes of Sec. 98.2(a)(2), the emissions from the industrial 
waste landfill are to be determined using the methane generation 
corrected for oxidation as determined using Equation TT-6 of this 
subpart times the global warming potential for methane in Table A-1 of 
subpart A of this part.



Sec. 98.462  GHGs to report.

    (a) You must report CH4 generation and CH4 
emissions from industrial waste landfills.
    (b) You must report CH4 destruction resulting from 
landfill gas collection and destruction devices, if present.
    (c) You must report under subpart C of this part (General Stationary 
Fuel Combustion Sources) the emissions of CO2, 
CH4, and N2O from each stationary combustion unit 
associated with the landfill gas destruction device, if present, by 
following the requirements of subpart C of this part.



Sec. 98.463  Calculating GHG emissions.

    (a) For each industrial waste landfill subject to the reporting 
requirements of this subpart, calculate annual modeled CH4 
generation according to the applicable requirements in paragraphs (a)(1) 
through (a)(3) of this section. Apply Equation TT-1 of this section for 
each waste stream disposed of in the landfill and sum the CH4 
generation rates for all waste streams disposed of in the landfill to 
calculate the total annual modeled CH4 generation rate for 
the landfill.
    (1) Calculate annual modeled CH4 generation using 
Equation TT-1 of this section.

[[Page 1095]]


Where:

GCH4 = Modeled methane generation in reporting year T (metric 
          tons CH4).
X = Year in which waste was disposed.
S = Start year of calculation. Use the year 1960 or the opening year of 
          the landfill, whichever is more recent.
T = Reporting year for which emissions are calculated.
WX = Quantity of waste disposed in the industrial waste 
          landfill in year X from measurement data and/or other company 
          records (metric tons, as received (wet weight)).
DOCX = Degradable organic carbon for waste disposed in year X 
          from Table TT-1 to this subpart or from measurement data [as 
          specified in paragraph (a)(3) of this section], if available 
          [fraction (metric tons C/metric ton waste)].
DOCF = Fraction of DOC dissimilated (fraction); use the 
          default value of 0.5. If measured values of DOC are available 
          using the 60-day anaerobic biodegradation test procedure 
          identified in Sec. 98.464(b)(4)(i), use a default value of 
          1.0.
MCF = Methane correction factor (fraction). Use the default value of 1 
          unless there is active aeration of waste within the landfill 
          during the reporting year. If there is active aeration of 
          waste within the landfill during the reporting year, use 
          either the default value of 1 or select an alternative value 
          no less than 0.5 based on site-specific aeration parameters.
F = Fraction by volume of CH4 in landfill gas (fraction, dry 
          basis, corrected to 0% oxygen). If you have a gas collection 
          system, use the annual average CH4 concentration 
          from measurement data for the current reporting year; 
          otherwise, use the default value of 0.5.
k = Decay rate constant from Table TT-1 to this subpart (yr-1). Select 
          the most applicable k value for the majority of the past 10 
          years (or operating life, whichever is shorter).

    (2) Waste stream quantities. Determine annual waste quantities as 
specified in paragraphs (a)(2)(i) through (ii) of this section for each 
year starting with January 1, 1960 or the year the landfills first 
accepted waste if after January 1, 1960, up until the most recent 
reporting year. The choice of method for determining waste quantities 
will vary according to the availability of historical data. Beginning in 
the first emissions reporting year (2011 or later) and for each year 
thereafter, use the procedures in paragraph (a)(2)(i) of this section to 
determine waste stream quantities. These procedures should also be used 
for any year prior to the first emissions reporting year for which the 
data are available. For other historical years, use paragraph (a)(2)(i) 
of this section, where waste disposal records are available, and use the 
procedures outlined in paragraph (a)(2)(ii) of this section when waste 
disposal records are unavailable, to determine waste stream quantities. 
Historical disposal quantities deposited (i.e., prior to the first year 
in which monitoring begins) should only be determined once, as part of 
the first annual report, and the same values should be used for all 
subsequent annual reports, supplemented by the next year's data on new 
waste disposal.
    (i) Determine the quantity of waste (in metric tons as received, 
i.e., wet weight) disposed of in the landfill separately for each waste 
stream by any one or a combination of the following methods.
    (A) Direct mass measurements.
    (B) Direct volume measurements multiplied by waste stream density 
determined from periodic density measurement data or process knowledge.
    (C) Mass balance procedures, determining the mass of waste as the 
difference between the mass of the process inputs and the mass of the 
process outputs.
    (D) The number of loads (e.g., trucks) multiplied by the mass of 
waste per load based on the working capacity of the container or 
vehicle.
    (ii) Determine the historical disposal quantities for landfills 
using the Waste Disposal Factor approach in paragraphs (a)(2)(ii)(A) and 
(B) of this section when historical production or processing data are 
available. If production or processing data are available for a given 
year, you must use Equation TT-3 of this section for that year. 
Determine historical disposal quantities using the method specified in 
paragraph (a)(2)(ii)(C) of this section when historical production or 
processing data are not available, and for waste streams received from 
an off-site facility when historical disposal quantities cannot be 
determined using the methods specified in paragraph (a)(2)(i) of this 
section.
    (A) Determining Waste Disposal Factor: For each waste stream 
disposed of in the landfill, calculate the average

[[Page 1096]]

waste disposal rate per unit of production or unit throughput using all 
available waste quantity data and corresponding production or processing 
rates for the process generating that waste or, if appropriate, the 
facility, using Equation TT-2 of this section.
[GRAPHIC] [TIFF OMITTED] TR12JY10.021

Where:

WDF = Average waste disposal factor as determined for the first annual 
          report required for this industrial waste landfill (metric 
          tons per production unit).
X = Year in which waste was disposed. Include only those years for which 
          disposal and production data are both available; the years do 
          not need to be sequential.
Y1 = First year in which disposal and production/throughput 
          data are both available.
Y2 = First year for which GHG emissions from this industrial 
          waste landfill must be reported.
N = Number of years for which disposal and production/throughput data 
          are both available.
Wx = Quantity of waste placed in the industrial waste 
          landfill in year X from measurement data and/or other company 
          records (metric tons, as received (wet weight)).
Px = Quantity of product produced or feedstock entering the 
          process or facility in year X from measurement data and/or 
          other company records (production units). You must use the 
          same basis for all years in the calculation. That is, 
          Px must be determined based on production (quantity 
          of product produced) for all ``N'' years or Px must 
          be determined based on throughput (quantity of feedstock) for 
          all ``N'' years.

    (B) Calculate waste: For each waste stream disposed of in the 
landfill, calculate the waste disposal quantities for historic years in 
which direct waste disposal measurements are not available using 
historical production data and Equation TT-3 of this section.
[GRAPHIC] [TIFF OMITTED] TR12JY10.022

Where:

X = Historic year in which waste was disposed.
Wx = Calculated quantity of waste placed in the landfill in 
          year X (metric tons).
WDF = Average waste disposal factor from Equation TT-2 of this section 
          (metric tons per production unit).
Px = Quantity of product produced or feedstock entering the 
          process or facility in year X from measurement data and/or 
          other company records (production units). You must use the 
          same basis for Px (either production only or 
          throughput only) as used to determine WDF in Equation TT-2 of 
          this section.

    (C) For any year in which historic production or processing data are 
not available such that historic waste quantities cannot be estimated 
using Equation TT-3 of this section, calculate an average annual bulk 
waste disposal quantity using either Equation TT-4a of this section when 
data are available consecutively for the most recent disposal years or 
Equation TT-4b of this section when data are available for sporadic 
(non-consecutive) years.
[GRAPHIC] [TIFF OMITTED] TR29NO11.005

Where:

WX = Quantity of waste placed in the landfill in year X 
          (metric tons, wet basis). This annual bulk waste disposal 
          quantity applies for all years from ``YrOpen'' to ``YrData'' 
          inclusive.
LFC = Capacity of the landfill used (or the total quantity of waste-in-
          place) at the end of the ``YrData'' from design drawings or 
          engineering estimates (metric tons). For closed landfills for 
          which waste quantity data are not available, use the 
          landfill's design capacity.
YrData = The year prior to the year when waste disposal data are first 
          available for all subsequent years from company records or 
          from Equation TT-3 of this section. For landfills for which 
          waste quantity data are not available, the year in which the 
          landfill last received waste.
YrOpen = Year 1960 or the year in which the landfill first received 
          waste from company records, whichever is more recent. If no 
          data are available for estimating

[[Page 1097]]

          YrOpen for a closed landfill, use 1960 as the default 
          ``YrOpen'' for the landfill.
          [GRAPHIC] [TIFF OMITTED] TR29NO11.006
          
Where:

WX = Quantity of waste placed in the landfill in year X 
          (metric tons, wet basis). This annual bulk waste disposal 
          quantity applies for all years for which waste quantity data 
          are not available from company records or from Equation TT-3 
          of this section.
WIP = Quantity of waste in-place at the start of the reporting year from 
          design drawings or engineering estimates (metric tons). For 
          closed landfills for which waste in-place quantities are not 
          available, use the landfill's design capacity.
Wmeas,n = Annual quantity of waste placed in the landfill for 
          the nth measurement year from company records or from Equation 
          TT-3 of this section.
YrLast = The last year, prior to the reporting year, that the landfill 
          received waste.
YrOpen = Year 1960 or the year in which the landfill first received 
          waste from company records, whichever is more recent. If no 
          data are available for estimating YrOpen for a closed 
          landfill, use 1960 as the default ``YrOpen'' for the landfill.
NYrData = The number of years for which annual waste disposal quantities 
          are available from company records or from Equation TT-3 of 
          this section from YrOpen to YrLast inclusive.

    (3) Degradable organic content (DOC). For any year, X, in Equation 
TT-1 of this section, use either the applicable default DOC values 
provided in Table TT-1 of this subpart or determine values for 
DOCx as specified in paragraphs (a)(3)(i) through (iv) of 
this section. When developing historical waste quantity data, you may 
use default DOC values from Table TT-1 of this subpart for certain years 
and determined values for DOCx for other years. The 
historical values for DOC or DOCx must be developed only for 
the first annual report required for the industrial waste landfill; and 
used for all subsequent annual reports (e.g., if DOC for year x = 1990 
was determined to be 0.15 in the first reporting year, you must use 0.15 
for the 1990 DOC value for all subsequent annual reports).
    (i) For the first year in which GHG emissions from this industrial 
waste landfill must be reported, determine the DOCx value of 
each waste stream disposed of in the landfill no less frequently than 
once per quarter using the methods specified in Sec. 98.464(b). 
Calculate annual DOCx for each waste stream as the arithmetic 
average of all DOCx values for that waste stream that were 
measured during the year.
    (ii) For subsequent years (after the first year in which GHG 
emissions from this industrial waste landfill must be reported), either 
use the DOCx of each waste stream calculated for the most 
recent reporting year for which DOC values were determined according to 
paragraph (a)(3)(i) of this section, or determine new DOC values for 
that year following the requirements in paragraph (a)(3)(i) of this 
section. You must determine new DOC values following the requirements in 
paragraph (a)(3)(i) of this section if changes in the process operations 
occurred during the previous reporting year that can reasonably be 
expected to alter the characteristics of the waste stream, such as the 
water content or volatile solids concentration. Should changes to the 
waste stream occur, you must revise the GHG Monitoring Plan as required 
in Sec. 98.3(g)(5)(iii) and report the new DOCx value 
according to the requirements of Sec. 98.466.
    (iii) If DOCx measurement data for each waste stream are 
available according to the methods specified in Sec. 98.464(b) for 
years prior to the first year in which GHG emissions from this 
industrial waste landfill must be reported, determine DOCx 
for each waste stream as the arithmetic average of all DOCx 
values for that waste stream that were measured in Year X. A single

[[Page 1098]]

measurement value is acceptable for determining DOCx for 
years prior to the first reporting year.
    (iv) For historical years for which DOCx measurement 
data, determined according to the methods specified in Sec. 98.464(b), 
are not available, determine the historical values for DOCx 
using the applicable methods specified in paragraphs (a)(3)(iv)(A) and 
(B) of this section. Determine these historical values for 
DOCx only for the first annual report required for this 
industrial waste landfill; historical values for DOCx 
calculated for this first annual report should be used for all 
subsequent annual reports.
    (A) For years in which waste stream-specific disposal quantities are 
determined (as required in paragraphs (a)(2) (ii)(A) and (B) of this 
section), calculate the average DOC value for a given waste stream as 
the arithmetic average of all DOC measurements of that waste stream that 
follow the methods provided in Sec. 98.464(b), including any 
measurement values for years prior to the first reporting year and the 
four measurement values required in the first reporting year. Use the 
resulting waste-specific average DOC value for all applicable years

determined) for which direct DOC measurement data are not available.
    (B) For years for which bulk waste disposal quantities are 
determined according to paragraphs (a)(2)(ii)(C) of this section, 
calculate the weighted average bulk DOC value according to the 
following: Calculate the average DOC value for each waste stream as the 
arithmetic average of all DOC measurements of that waste stream that 
follows the methods provided in Sec. 98.464(b) (generally, this will 
include only the DOC values determined in the first year in which GHG 
emissions from this industrial waste landfill must be reported); 
calculate the average annual disposal quantity for each waste stream as 
the arithmetic average of the annual disposal quantities for each year 
in which waste stream-specific disposal quantities have been determined; 
and calculate the bulk waste DOC value using Equation TT-5 of this 
section. Use the bulk waste DOC value as DOCx for all years 
for which bulk waste disposal quantities are determined according to 
paragraphs (a)(2)(ii)(C) of this section.

Sec. 98.464  Monitoring and QA/QC requirements.

    (a) For calendar year 2011 monitoring, the facility may submit a 
request to the Administrator to use one or more best available 
monitoring methods as listed in Sec. 98.3(d)(1)(i) through (iv). The 
request must be submitted no later than October 12, 2010 and must 
contain the information in Sec. 98.3(d)(2)(ii). To obtain approval, the 
request must demonstrate to the Administrator's satisfaction that it is 
not reasonably feasible to acquire, install, and operate a required 
piece of monitoring equipment by January 1, 2011. The use of best 
available monitoring methods will not be approved beyond December 31, 
2011.
    (b) For each waste stream placed in the landfill during the 
reporting year for which you choose to determine volatile solids 
concentration and/or a waste stream-specific DOCX, you must 
collect and test a representative sample of that waste stream using the 
methods specified in paragraphs (b)(1) through (b)(4) of this section, 
as applicable.
    (1) Develop and follow a sampling plan to collect a representative 
sample (in terms of composition and moisture content) of each waste 
stream placed in the landfill for which testing is elected.
    (2) Determine the percent total solids and the percent volatile 
solids of each sample following Standard Method 2540G ``Total, Fixed, 
and Volatile Solids in Solid and Semisolid Samples'' (incorporated by 
reference; see Sec. 98.7).
    (3) For the purposes of Sec. 98.460(c)(2)(xii), the volatile solids 
concentration (weight percent on a dry basis) is the percent volatile 
solids determined using Standard Method 2540G ``Total, Fixed, and 
Volatile Solids in Solid and Semisolid Samples'' (incorporated by 
reference; see Sec. 98.7).
    (4) Determine DOC value of a waste stream by either using at least a 
60-day anaerobic biodegradation test as specified in paragraph (b)(4)(i) 
of this section or by estimating the DOC value based on the total and 
volatile solids measurements as specified in paragraph (b)(4)(ii) of 
this section.
    (i) Perform an anaerobic biodegradation test and determine the DOC 
value of a waste stream following the procedures and requirements in 
paragraphs (b)(4)(i)(A) through (E) of this section.
    (A) You may use the procedures published by a consensus-based 
standards organization to conduct a minimum of a 60-day anaerobic 
biodegradation test. Consensus-based standards organizations include, 
but are not limited to, the following: ASTM International (100 Barr 
Harbor Drive, P.O. Box CB700, West Conshohocken, Pennsylvania 19428-
B2959, (800) 262-1373, http://www.astm.org), the American National 
Standards Institute (ANSI, 1819 L Street, NW., 6th floor, Washington, DC 
20036, (202) 293-8020, http://www.ansi.org), the American Society of 
Mechanical Engineers (ASME, Three Park Avenue, New York, NY 10016-5990, 
(800) 843-2763,

[[Page 1100]]

http://www.asme.org), and the North American Energy Standards Board 
(NAESB, 801 Travis Street, Suite 1675, Houston, TX 77002, (713) 356-
0060, http://www.api.org).
    (B) Use a minimum of four samples: Two waste stream samples, a 
control sample using a known substrate (such as ethanol), and a digester 
sludge blank sample. Each waste stream sample must be appropriately 
ground to ensure the waste material is fully exposed to the anaerobic 
digester sludge.
    (C) Determine the net mass of carbon degraded in the control sample 
as the difference in the results of the control sample and the digester 
sludge blank sample. Determine the net mass of carbon degraded in each 
waste stream sample as the difference in the results of each waste 
stream sample and the digester sludge blank sample.
    (D) Determine the fraction of carbon degraded in the control sample 
as the net mass of carbon degraded in the control sample divided by the 
mass of carbon added via the substrate material in the control sample. 
If less than 50 percent of the theoretical mass of carbon in the control 
sample is degraded, the test run is invalid.
    (E) Determine the DOC of each waste sample using Equation TT-7 of 
this section. If the DOC values for the two waste stream samples differ 
by more than 20 percent, the test run is invalid. The DOC of the waste 
stream is determined as the average DOC value of the two waste stream 
samples determined during a valid test.

    (c) For each waste stream that was historically managed in the 
landfill for which you choose to determine volatile solids concentration 
and/or a waste stream-specific DOCX, you must determine 
volatile solids concentration or DOCX of the waste stream as 
initially placed in the landfill using the methods specified in 
paragraph (c)(1) or (2) of this section, as applicable.

that was historically managed in the landfill, you must determine the 
volatile solids

[[Page 1101]]

concentration or DOCX of the similar waste stream using the 
applicable procedures in paragraphs (b)(1) through (4) of this section.
    (2) If you cannot identify a similar waste stream to the waste 
stream that was historically managed in the landfill, you may determine 
the volatile solids concentration or DOCX of the historically 
managed waste stream using process knowledge. You must document the 
basis for the volatile solids concentration or DOCX value as 
determined through process knowledge.
    (d) For landfills with gas collection systems, operate, maintain,

maintain, and calibrate a gas flow meter capable of measuring the 
volumetric flow rate of the recovered landfill gas according to the 
requirements specified at Sec. 98.344(c).
    (f) For landfills with gas collection systems, all temperature, 
pressure, and if applicable, moisture content monitors must be

manufacturer.
    (g) For landfills electing to measure the fraction by volume of 
CH4 in landfill gas (F), follow the requirements in 
paragraphs (g)(1) and (g)(2) of this section.
    (1) Use a gas composition monitor capable of measuring the 
concentration of CH4 on a dry basis that is properly 
operated, calibrated, and maintained according to the requirements 
specified at Sec. 98.344(b). You must either use a gas composition 
monitor that is also capable of measuring the O2 
concentration correcting for excess (infiltration) air or you must 
operate, maintain, and calibrate a second monitor capable of measuring 
the O2 concentration on a dry basis according to the 
manufacturer's specifications.
    (2) Use Equation TT-9 of this section to correct the measured 
CH4 concentration to 0% oxygen. If multiple CH4 
concentration measurements are made during the reporting year, determine 
F separately for each measurement made during the reporting year, and 
use the results to determine the arithmetic average value of F for use 
in Equation TT-1 of this part.

Sec. 98.468  Definitions.

    Except as provided below, all terms used in this subpart have the 
same meaning given in the CAA and subpart A of this part.
    Construction and demolition (C&D) waste landfill means a solid waste 
disposal facility subject to the requirements of subparts A or B of part 
257 of this chapter that receives construction and demolition waste and 
does not receive hazardous waste (defined in Sec. 261.3 of this 
chapter) or industrial solid waste (defined in Sec. 258.2 of this 
chapter) or municipal solid waste (defined in Sec. 98.6 of this part) 
other than residential lead-based paint waste. A C&D waste landfill 
typically receives any one or more of the following types of

[[Page 1104]]

solid wastes: roadwork material, excavated material, demolition waste, 
construction/renovation waste, and site clearance waste.
    Design capacity means the maximum amount of solid waste a landfill 
can accept. For the purposes of this subpart, for landfills that have a 
permit, the design capacity can be determined in terms of volume or mass 
in the most recent permit issued by the state, local, or Tribal agency 
responsible for regulating the landfill, plus any in-place waste not 
accounted for in the most recent permit. If the owner or operator 
chooses to convert the design capacity from volume to mass to determine 
its design capacity, the calculation must include a site-specific 
density. If the design capacity is within 10 percent of the 
applicability threshold in Sec. 98.460(a) and there is a change in the 
production process that can reasonably be expected to change the site-
specific waste density, the site-specific waste density must be 
redetermined and the design capacity must be recalculated based on the 
new waste density.
    Industrial sludge means the residual, semi-solid material left from 
industrial wastewater treatment processes or wet air pollution control 
devices (e.g., wet scrubbers). Industrial sludge includes underflow 
material collected in primary or secondary clarifiers, settling basins, 
or precipitation tanks as well as dredged materials from wastewater 
tanks or impoundments. Industrial sludge also includes the semi-solid 
materials remaining after these materials are dewatered via a belt 
process, centrifuge, or similar dewatering process.
    Solid waste has the meaning established by the Administrator 
pursuant to the Solid Waste Disposal Act (42 U.S.C.A. 6901 et seq.).
    Waste stream means industrial solid waste material that is generated 
by a specific manufacturing process or client. For wastes generated at 
the facility that includes the industrial waste landfill, a waste stream 
is the industrial solid waste material generated by a specific 
processing unit at that facility. For industrial solid wastes that are 
received from off-site facilities, a waste stream can be defined as each 
waste shipment or group of waste shipments received from a single client 
or group of clients that produce industrial solid wastes with similar 
waste properties.

\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.

comprises any well or group of wells that inject a CO2 stream 
into the subsurface.
    (b) If you report under subpart RR of this part for a well or group 
of wells, you are not required to report under this subpart for that 
well or group of wells.
    (c) A facility that is subject to this part only because it is 
subject to subpart UU of this part is not required to report emissions 
under subpart C of this part or any other subpart listed in Sec. 
98.2(a)(1) or (a)(2).



Sec. 98.471  Reporting threshold.

    (a) You must report under this subpart if your facility injects any 
amount of CO2 into the subsurface.

Sec. 98.474  Monitoring and QA/QC requirements.

    (a) CO2 received. (1) You must determine the quarterly 
flow rate of CO2 received by pipeline by following the most 
appropriate of the following procedures:
    (i) You may measure flow rate at the receiving custody transfer 
meter prior to any subsequent processing operations at the facility and 
collect the flow rate quarterly.
    (ii) If you took ownership of the CO2 in a commercial 
transaction, you may use the quarterly flow rate data from the sales 
contract if it is a one-time transaction or from invoices or manifests 
if it is an ongoing commercial transaction with discrete shipments.
    (iii) If you inject CO2 from a production process unit 
that is part of your facility, you may use the quarterly CO2 
flow rate that was measured at the equivalent of a custody transfer 
meter following procedures provided in subpart PP of this part. To be 
the equivalent of a custody transfer meter, a meter must measure the 
flow of CO2 being transported to an injection well to the 
same degree of accuracy as a meter used for commercial transactions.
    (2) You must determine the quarterly mass or volume of contents in 
all containers if you receive CO2 in containers by the most 
appropriate of the following procedures:
    (i) You may measure the mass of contents of containers summed 
quarterly using weigh bills, scales, or load cells.
    (ii) You may determine the volume of the contents of containers 
summed quarterly.
    (iii) If you took ownership of the CO2 in a commercial 
transaction, you may use the quarterly mass or volume of contents from 
the sales contract if it is a one-time transaction or from invoices or 
manifests if it is an ongoing commercial transaction with discrete 
shipments.
    (3) You must determine a quarterly concentration of the 
CO2 received that is representative of all CO2 
received in that quarter by following the most appropriate of the 
following procedures:
    (i) You may sample the CO2 stream at least once per 
quarter at the point of receipt and measure its CO2 
concentration.
    (ii) If you took ownership of the CO2 in a commercial 
transaction for which the sales contract was contingent on 
CO2 concentration, and if the supplier of the CO2 
sampled the CO2 stream in a quarter and measured its 
concentration per the sales contract terms, you may use the 
CO2 concentration data from the sales contract for that 
quarter.
    (iii) If you inject CO2 from a production process unit 
that is part of your facility, you may report the quarterly 
CO2 concentration of the CO2 stream supplied that 
was measured following procedures provided in subpart PP of this part as 
the quarterly CO2 concentration of the CO2 stream 
received.
    (4) You must assume that the CO2 you receive meets the 
definition of a CO2 stream unless you can trace it through 
written records to a source other than a CO2 stream.
    (b) Measurement devices. (1) All flow meters must be operated 
continuously except as necessary for maintenance and calibration.
    (2) You must calibrate all flow meters used to measure quantities 
reported in Sec. 98.476 according to the calibration and accuracy 
requirements in Sec. 98.3(i).
    (3) You must operate all measurement devices according to one of the 
following. You may use an appropriate

[[Page 1108]]

standard method published by a consensus-based standards organization if 
such a method exists or an industry standard practice. Consensus-based 
standards organizations include, but are not limited to, the following: 
ASTM International, the American National Standards Institute (ANSI), 
the American Gas Association (AGA), the American Society of Mechanical 
Engineers (ASME), the American Petroleum Institute (API), and the North 
American Energy Standards Board (NAESB).
    (4) You must ensure that any flow meter calibrations performed are 
National Institute of Standards and Technology (NIST) traceable.
    (c) General. (1) If you measure the concentration of any 
CO2 quantity for reporting, you must measure according to one 
of the following. You may use an appropriate standard method published 
by a consensus-based standards organization if such a method exists or 
an industry standard practice.
    (2) You must convert all measured volumes of CO2 to the 
following standard industry temperature and pressure conditions for use 
in Equation UU-2 of this subpart: Standard cubic meters at a temperature 
of 60 degrees Fahrenheit and at an absolute pressure of 1 atmosphere.
    (3) For 2011, you may follow the provisions of Sec. 98.3(d)(1) 
through (2) for best available monitoring methods rather than follow the 
monitoring requirements of this section. For purposes of this subpart, 
any reference to the year 2010 in Sec. 98.3(d)(1) through (2) shall 
mean 2011.
