b)
				The following formulas must be used to determine the number of CASA allowances
				that may be allocated to a project per control period:
1) For an energy efficiency and conservation
				project pursuant to Section
				225.460(a)(1)
				through (a)(4)(A), the number of allowances
				must be calculated using the number of megawatt hours of electricity that was
				not consumed during a control period and the following formula:
A
=
(MWhc) a (1.5 lb/MWh) / 2000
							 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhc
=
The number of megawatt hours of electricity conserved
							 or generated during a control period by a project.
2)
				For a zero emission electric generating project pursuant to Section
				225.460(b)(1),
				the number of allowances must be calculated using the number of megawatt hours
				of electricity generated during a control period and the following formula:
A
=
(MWhg) a (2.0 lb/MWh) / 2000
							 lb
Where:
A
=
The number of allowances for a particular
							 project
MWhg
=
The number of megawatt hours of electricity generated
							 during a control period by a project.
3)
				For a renewable energy emission unit pursuant to Section
				225.460(b)(2),
				the number of allowances must be calculated using the number of MWhs of
				electricity generated during a control period and the following formula:
A
=
(MWhg) ' (0.5 lb/MWh) / 2000
							 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhg
=
The number of MW hours of electricity generated
							 during a control period by a project.
4)
				For an air pollution control equipment upgrade project pursuant to Section
				225.460(c)(1),
				the number of allowances will be calculated as follows:
A) For NOx or
				SO2 control projects, by determining the difference in
				emitted NOx or SO2 per control
				period using the emission rate before and after replacement or improvement, and
				the following formula:
A
=
(MWhg) ' K '
							 (ERB lb/MWh - ERA lb/MWh) / 2000
							 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhg
=
The number of megawatt hours of electricity generated
							 during a control period by a project.
K
=
The pollutant factor: for NOx,
							 K= 0.1; and for SO2, K = 0.05.
ERB
=
Average NOx or
							 SO2 emission rate based on CEMS data from the most
							 recent two control periods prior to the replacement or improvement of the
							 control equipment in lb/MWh, unless subject to a court order or consent decree.
							 For units subject to a court order or consent decree entered into before May
							 30, 2006, ERB is limited to emission rates that are
							 lower than the emission rate required in the consent decree or court order. For
							 a court order or consent decree entered into after May 30, 2006,
							 ERB is limited to the lesser of the emission rate
							 specified in the court order or consent decree or the actual average emission
							 rate during the control period. If such limit is not expressed in lb/MWh, the
							 limit must be converted into lb/MWh using a heat rate of 10 mmBtu/1 MW.
ERA
=
Annual NOx or
							 SO2 average emission rate for the applicable control
							 period data based on CEMS data in lb/MWh.
B)
				For a baghouse project:
A
=
(MWhg) ' (Q lb/MWh) / 2000
							 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhg
=
The number of MWh of electricity generated during a
							 control period or the portion of a control period that the units were
							 controlled by the baghouse.
Q
=
* If a baghouse was not installed pursuant to a
							 consent decree or court order, 0.2.
* If a baghouse was installed pursuant to a consent
							 decree or court order that assigns a Q factor, the factor established in the
							 consent decree or court order but must not exceed a factor of 0.2.
* If a baghouse was installed pursuant to a consent
							 decree or court order that does not assign a Q factor, then Q shall
							 equal:
Q = 0.25 - (P ' ERq)
Where:
P
=
If the most recent control period's average PM
							 emission rate was based on PM CEMS data, 1.0; otherwise
							 1.1.
ERq
=
The magnitude of the most recent control period's
							 average PM emission rate in lb/MWh exiting the baghouse, subject to the
							 following limits:
If P
=
1.0, then 1/10 [LESS THAN OR EQUAL TO]
							 ERq [LESS THAN OR EQUAL TO] 2/10
If P
=
1.1, then 1/11 [LESS THAN OR EQUAL TO]
							 ERq [LESS THAN OR EQUAL TO] 2/11
* If the ERq is less than the
							 lower limit, the lower limit shall be used.
* If ERq is greater than the
							 upper limit, the upper limit shall be used.
* If ERq is not expressed in
							 lb/MWh, the number must be converted to lb/MWh using a heat rate of 10 mmBtu/1
							 MW.
5) For highly efficient power generation and
				clean coal technology projects:
A) For
				projects other than fluidized coal combustion pursuant to Section
				225.460(a)(4)(B),
				(a)(4)(C), and (c)(2), the number of
				allowances must be calculated using the number of MWh of electricity the
				project generates during a control period and the following formula:
A
=
(MWhg) ' (1.0 lb/MWh - ER
							 lb/MWh) / 2000 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhg
=
The number of megawatt hours of electricity generated
							 during a control period by a project.
ER
=
Annual average NOx emission
							 rate based on CEMS data in lb/MWh.
B)
				For fluidized bed coal combustion projects pursuant to Section
				225.460(c)(2),
				the number of allowances shall be calculated using the number of gross MWh of
				electricity the project generates during a control period and the following
				formula:
A
=
(MWhg) ' (1.4 lb/MWh - ER
							 lb/MWh) / 2000 lb
Where:
A
=
The number of allowances for a particular
							 project.
MWhg
=
The number of gross MWh of electricity generated
							 during a control period by a project.
ER
=
Annual NOx emission rate for
							 the control period based on CEMS data in lb/MWh.
6) For a CASA project that commences
				construction before December 31, 2012, in addition to the allowances allocated
				pursuant to subsections (b)(1) through (b)(5) of this Section, a project
				sponsor may also request additional allowances pursuant to the early adopter
				project category pursuant to Section
				225.460(e)
				based on the following formula:
A
=
1.0 + 0.10 ' [SIGMA] Ai
Where:
A
=
The number of allowances for a particular project as
							 determined in subsections (b)(1) through (b)(5) of this Section.
Ai
=
The number of allowances as determined in subsection
							 (b)(1), (b)(2), (b)(3), (b)(4) or (b)(5) of this Section for a given
							 project.
