    (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

the calendar year for which such deductions are or could be made) and
transferred to the general account in accordance with subpart GGG of
this part or subpart D of part 73 of this chapter.
    (c) Serial numbers for allocated CAIR SO2 allowances. When

permitting authority under 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.
    (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 of the information in the submissions.
    (2) The Administrator may deduct CAIR SO2 allowances
from or transfer CAIR SO2 allowances to a source's
compliance account based on the information in the submissions, as
adjusted under paragraph (f)(1) of this section, and record such
deductions and transfers.

Sec.  97.255  Banking.

    (a) CAIR SO2 allowances 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 CAIR SO2 allowance that is held in a compliance

    (2) Unless the permitting authority issues a notification of
acceptance of withdrawal of the CAIR SO2 opt-in unit from
the CAIR SO2 Trading Program in accordance with Sec.  97.286
or the unit becomes a CAIR SO2 unit under Sec.  97.204, the
CAIR SO2 opt-in unit shall remain subject to the
requirements for a CAIR SO2 opt-in unit, even if the CAIR
designated representative for the CAIR SO2 opt-in unit fails
to submit a CAIR permit application that is required for renewal of the
CAIR opt-in permit under paragraph (b)(1) of this section.

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 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 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 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 (b)(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 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.

Sec.  97.285  CAIR opt-in permit contents.

    (a) Each CAIR opt-in permit will contain:
    (1) All elements required for a complete CAIR permit application
under Sec.  97.222;
    (2) The certification in Sec.  97.283(a)(2);
    (3) The unit's baseline heat input under Sec.  97.284(c);
    (4) The unit's baseline SO2 emission rate under Sec.
97.284(d);
    (5) A statement whether the unit is to be allocated CAIR
SO2 allowances under Sec.  97.288(b) or Sec.  97.288(c)
(subject to the conditions in Sec. Sec.  97.284(h) and 97.286(g));
    (6) A statement that the unit may withdraw from the CAIR
SO2 Trading Program only in accordance with Sec.  97.286;
and
    (7) A statement that the unit is subject to, and the owners and
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.
    (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.
    (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
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 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
paragraph (b)(1) of this section.

    (ii) The SO2 emission rate (in lb/mmBtu) used for
calculating CAIR SO2 allowance allocations will be the
lesser of:
    (A) The CAIR SO2 opt-in unit's baseline SO2
emissions rate (in lb/mmBtu) determined under Sec.  97.284(d); or
    (B) The most stringent State or Federal SO2 emissions
limitation applicable to the CAIR SO2 opt-in unit at any
time during the control period in which the CAIR SO2 opt-in
unit enters the CAIR SO2 Trading Program under Sec.
97.284(g).
    (iii) 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 (c)(1)(i) of this section, multiplied by the
SO2 emission rate under paragraph (c)(1)(ii) of this
section, and divided by 2,000 lb/ton.
    (2) For each control period in 2015 and thereafter for which the
CAIR SO2 opt-in unit is to be allocated CAIR SO2
allowances,
    (i) The heat input (in mmBtu) used for calculating the CAIR
SO2 allowance allocations will be determined as described in
paragraph (b)(1) of this section.
    (ii) The SO2 emission rate (in lb/mmBtu) used for
calculating the CAIR SO2 allowance allocation will be the
lesser of:
    (A) The CAIR SO2 opt-in unit's baseline SO2
emissions rate (in lb/mmBtu) determined under Sec.  97.284(d)
multiplied by 10 percent; or
    (B) 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.
    (iii) 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 (c)(2)(i) of this section, multiplied by the
SO2 emission rate under paragraph (c)(2)(ii) of this
section, and divided by 2,000 lb/ton.
    (d) Recordation. 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 Administrator will record, in the compliance account of the
source that includes the CAIR SO2 opt-in unit, the CAIR
SO2 allowances allocated by the permitting authority to the
CAIR SO2 opt-in unit under paragraph (a)(1) of this section.
    (2) By December 1 of the control period in which a CAIR
SO2 opt-in unit enters the CAIR SO2 Trading
Program under Sec.  97.284(g) and December 1 of each year thereafter,
the Administrator will record, in the compliance account of the source
that includes the CAIR SO2 opt-in unit, the CAIR
SO2 allowances allocated by the permitting authority to the
CAIR SO2 opt-in unit under paragraph (a)(2) of this section.
