Standard Requirements
General. This source is subject to the standard requirements in 40 CFR 72.9 (consistent with 40 CFR 76.8(e)(1)(i)).
These requirements are listed in this source's Acid Rain Permit.
Special Provisions for Early Election Units
Nitrogen Oxides. A unit that is governed by an approved early election plan shall be subject to an emissions limitation
for NOx as provided under 40 CFR 76.8(a)(2) except as provided under 40 CFR 76.8(e)(3)(iii).
Liability. The owners and operators of a unit governed by an approved early election plan shall be liable for any
violation of the plan or 40 CFR 76.8 at that unit. The owners and operators shall be liable, beginning January 1, 2000,
for fulfilling the obligations specified in 40 CFR Part 77.
Termination. An approved early election plan shall be in effect only until the earlier of January 1, 2008 or January 1 of
the calendar year for which a termination of the plan takes effect. If the designated representative of the unit under an
approved early election plan fails to demonstrate compliance with the applicable emissions limitation under 40 CFR
76.5 for any year during the period beginning January 1 of the first year the early election takes effect and ending
December 31, 2007, the permitting authority will terminate the plan. The termination will take effect beginning January
1 of the year after the year for which there is a failure to demonstrate compliance, and the designated representative
may not submit a new early election plan. The designated representative of the unit under an approved early election
plan may terminate the plan any year prior to 2008 but may not submit a new early election plan. In order to terminate
the plan, the designated representative must submit a notice under 40 CFR 72.40(d) by January 1 of the year for
which the termination is to take effect. If an early election plan is terminated any year prior to 2000, the unit shall meet,
beginning January 1, 2000, the applicable emissions limitation for NOx for Phase II units with Group 1 boilers under 40
CFR 76.7. If an early election plan is terminated on or after 2000, the unit shall meet, beginning on the effective date of
the termination, the applicable emissions limitation for NOx for Phase II units with Group 1 boilers under 40 CFR 76.7.

Acid Rain Program
Instructions for Phase II NOx Compliance
Plan (40 CFR 76.9)
The U.S. Environmental Protection Agency has promulgated regulations designed to substantially reduce the annual emissions of
nitrogen oxides (NOx) from coal-fired electric utilities. The NOx Emission Reduction regulations are found at 40 CFR part 76 and apply to
each existing coal-fired utility unit that is subject to sulfur dioxide (SO2) emission reduction requirements under Sections 404, 405, or 409
of the Clean Air Act. Under 40 CFR 76.9, the owner or operator of each affected unit subject to 40 CFR part 76 must include a compliance
plan for NOx emissions in the Acid Rain permit application for that unit. The designated representatives (DRs) of Phase I and Phase II
NOx-affected units with Group 1 or Group 2 boilers must submit an initial Phase II NOx compliance plan to the appropriate title V air
permitting authority (in most cases, the State or local air permitting authority) not later than January 1, 1998. A Group 1 boiler is a
tangentially fired boiler or a dry bottom wall-fired boiler. A Group 2 boiler is a cell burner boiler, cyclone boiler, vertically fired boiler, or a
wet bottom boiler. Once the title V permitting authority receives the Phase II NOx compliance plans, it will in turn review them and
incorporate approved plans into the Phase II Acid Rain permits issued by the permitting authority to Phase II affected sources.

NOx Compliance Options
STEP 2
General

NO -affected Units

Indicate a proposed method of compliance with the NOx
emissions requirements for each unit at the source affected for
NOx during Phase II. A Phase II NOx compliance plan must
account for each year the Phase II acid rain permit will be
effective. Further, a NOx compliance plan is in effect only
through the term of the acid rain permit covering the NOxaffected units. A new NOx compliance plan must be
submitted when an acid rain permit renewal application is
due.

To determine if an affected unit subject to Acid Rain SO2
requirements is also subject to NOx emission limitations, see 40
CFR 76.1, the definitions at 40 CFR 76.2, and the emission
limitations at 40 CFR 76.5, 76.6, and 76.7. Most existing coalfired units that are subject to Acid Rain SO2 requirements and
that have a Group 1 or Group 2 boiler are also subject to the
NOx emission limitations under 40 CFR part 76.

X

2
Phase I Group 1 Boilers
Compliance options (a) and (b) are standard annual emission
limitations, one of which may be selected for a Phase I Group 1
boiler. The limits also apply to Phase II Group 1 boilers that are
covered by an early election plan previously approved by U.S.
EPA.
Early Election
Compliance option (c), NOx early election, is available only to
Phase II Group 1 boilers with early election plans submitted by
January 1, 1997 and approved by U.S. EPA. All such plans
terminate no later than December 31, 2007. DRs with NOx early
election units must select option (c) and either (a) or (b), the
Phase I Group 1 standard emissions limit specified for the unit in
the plan. If the termination date of the plan will be prior to the
expiration date of the acid rain permit covering an early election
unit, the DR must indicate an additional NOx compliance option
that will apply to the unit beginning when the plan terminates
through the date by which the acid rain permit will expire. In
such cases the DR must mark option (c) and either (a) or (b), as
well as the additional box(es) denoting the additional, follow-on
NOx compliance option. For early election units in a common
stack, see also the instructions under Common Stacks.
Phase II Group 1 Boilers
Compliance options (d) and (e) denote standard annual
emission limitations, one of which may be selected for a Phase
II Group 1 boiler.
Phase II Group 2 Boilers
Compliance options (f) through (i) denote standard annual
emission limitations, one of which may be selected for a Phase
II Group 2 boiler.
NOx Averaging
Compliance option (j) denotes the annual emission limitation
under a NOx averaging plan, which may be selected in lieu of a
standard annual emission limit for Group 1 or Group 2 boilers
with the same owner or operator and the same DR. See
instructions below and include Phase II NOx averaging form.
Common Stacks
A unit that utilizes a common stack and is separately monitored
for NOx (i.e, has its own NOx monitor and diluent monitor) is
treated as the same as a unit that emits only through its own
separate stack.
A unit (other than an early election unit) that utilizes a common
stack and is not monitored separately must select one of the
applicable common stack options. If the unit shares a common
stack with other affected units and no non-affected units and if
each of the units has a NOx emission limitation, three options
are available: comply with the most stringent NOx emission

limitation applicable to any unit utilizing the common stack
(option (k)); include the units in a NOx averaging plan (option
(l)); or use an approved method for apportioning the combined
NOx emission rate in the common stack (option (m)). If the unit
shares a common stack with at least one other unit that does
not have a NOx emission limitation or with at least one nonaffected unit, you must use an approved method for
apportioning the combined NOx emission rate (option (m)),
unless, of course, the unit is separately monitored. An early
election unit that utilizes a common stack, that is not monitored
separately, and whose early election plan specifies option (k) or
(m) for the unit, must select such option.
If an apportionment option is chosen, check, in addition to
option (m), the box at Step 2 that indicates the applicable
emission limitation and submit to U.S. EPA the documentation
supporting apportionment with the monitoring plan submission.
Alternative Emissions Limitations
Compliance option (n) must be selected by a Phase II Group 1
or Group 2 boiler that is applying for an AEL demonstration
period, or final AEL, starting in Phase II. Compliance option (n)
must also be chosen by a boiler that is renewing for Phase II a
final AEL approved by U.S. EPA (see instructions
accompanying Phase II AEL Demonstration Period, Final AEL
Petition, and AEL Renewal forms and include appropriate form).
Compliance option (o) must be selected by a boiler that has
applied to U.S. EPA for an AEL demonstration period or final
AEL which is undergoing review by U.S. EPA. If a final AEL is
subsequently approved by U.S. EPA, a revised Phase II NOx
compliance plan must be submitted marking option (o) and
attaching an AEL Renewal form. If an AEL demonstration
period or final AEL is subsequently disapproved by U.S. EPA, a
revised Phase II NOx compliance plan must be submitted
indicating which Phase II NOx compliance option will be used by
the boiler.
Repowering Extension Plans
Compliance option (p) must be selected by a boiler that is
covered by either an approved repowering extension plan or a
plan that is undergoing review. If a repowering extension plan
undergoing review is subsequently disapproved, a revised
Phase II NOx compliance plan must be submitted indicating
which Phase II NOx compliance option will be used by the
boiler. If the termination date of either the repowering extension
plan undergoing review or the approved plan is prior to the
expiration date of the acid rain permit covering the repowered
(or replacement) boiler under the plan, the DR must indicate an
additional NOx compliance option that will apply to the boiler
beginning when the plan terminates through the date by which
the acid rain permit will expire. In such cases the DR must mark
option (p), as well as additional box(es) denoting the additional,
follow-on NOx compliance option.

3

NOx Averaging Plan
Under 40 CFR 76.11 any affected units under control of the same owner or operator and with the same designated representative
may average their NOx emission rate, rather than each unit complying on an individual-unit basis with the applicable emission limitation in
40 CFR 76.5, 76.6, or 76.7. Units with no common owner or operator may not average their emissions. You may submit an averaging plan
(or a revision to an approved averaging plan) with the appropriate title V permitting authority(s) at any time up to and including January 1
of the calendar year for which the averaging plan will become effective. If the plan is restricted to units located within a single permitting
authority's jurisdiction, you may submit the plan at any time up to and including July 1 of the calendar year for which the plan will become
effective.
STEP 1

STEP 2

Each unit identified for inclusion in the averaging plan in Phase
II must be a Group 1 or Group 2 boiler subject to an emission
limitation under 40 CFR 76.5, 76.6, or 76.7. Enter each unit's
applicable emission limitation from 40 CFR 76.5, 76.6, or 76.7 in
column (a). If a unit with an alternative emission limitation
demonstration period or a final alternative emission limitation
under 40 CFR 76.10 participates in an averaging plan, enter the
applicable emission limitation from 40 CFR 76.5, 76.6, or 76.7,
not the interim or alternative limit, in column (a).

The entries in Step 2 must demonstrate that the Btu-weighted
annual emission rate averaged over the units in the plan is less
than or equal to the Btu-weighted annual average emission rate
for the same units if they are each operated, during the same
period of time, in compliance with the applicable emission
limitations in 40 CFR 76.5, 76.6, or 76.7. Use the equation that
appears in Step 2 to demonstrate that the alternative
contemporaneous annual emission limitations and annual heat
input values assigned to the units in Step 1 satisfy this criterion.
For units with an interim emission limitation or an alternative
emission limitation, the applicable emission limitation for the
equation shall equal the applicable emissions limitation under
40 CFR 76.5, 76.6, or 76.7.

For units utilizing a common stack that are averaging pursuant
to 40 CFR 75.17(a)(2)(i)(B), the same alternative
contemporaneous emission limitation must be entered in column
(b) for each unit utilizing the common stack. Different annual
heat input limits may be entered for these units in column (c).
Units not utilizing the common stack may also be included in the
averaging plan with the common stack units.
The annual heat input limit entered at column (c) will be a
minimum limit if the value in column (b) is less than the value in
column (a) for that unit. It will be a maximum limit if the value in
column (b) is greater than the value in column (a). The values
entered for each unit at columns (b) and (c) must satisfy the
formula at Step 2.

STEP 3
The second option is included to avoid the need to submit
identical plans each for a different year if you want each plan to
be effective for only one year.
