Identify each affected Group 1 and Group 2 boiler using the unit IDs from the current Certificate of
Representation covering the facility. Also indicate the boiler type: "CB" for cell burner, "CY" for
cyclone, "DBW" for dry bottom wall-fired, "T" for tangentially fired, "V" for vertically fired, and "WB"
for wet bottom, and select the compliance option for each unit by making an ‘X’ in the appropriate row
and column.

Instructions for Acid Rain NOX Compliance Plan
and Averaging Plan (40 CFR 76.9)
The Acid Rain Program NOX regulations are found at 40 CFR part 76 and apply to each existing coal-fired utility unit that is
subjectto sulfur dioxide (SO2) emission reduction requirements under Sections 404, 405, or 409 of the Clean Air Act.
Under 40 CFR 76.9, theowner or operator of each affected unit subject to 40 CFR part 76 must include a NOX compliance
plan in the Acid Rain permit application that covers that unit. For assistance, please send an email to [email protected] or
call the Clean Air Markets Hotline at (202) 343- 9620.

Acid Rain NOX Compliance Plan Instructions
STEP 1
Enter the plant name and plant code used in the Certificate of Representation covering the facility.
STEP 2
For each boiler subject to an Acid Rain NO limit, enter the boiler (unit) ID #, (consistent with the unit ID # listed for the unit on the
Certificate of Representation covering the facility) and check either (1) the appropriate box denoting the standard limit that the unit is
subject to in row (a) through (h) or (2) the NOX averaging plan box in row (i) (if a box in row “i” is checked, a NOX Averaging Plan form
must also be submitted with the NOX compliance plan). If applicable, one of the boxes in rows (j) through (l) may also be checked. See
the “Common Stacks” paragraph immediately below.
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 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
(i)); include the units in a NOX averaging plan (option (k)); or use an approved method for apportioning the combined NOX emission
rate in the common stack (option (l)). 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 non-affected unit, you must use an approved method for apportioning the combined NOX emission rate
(option (l)), unless, of course, the unit is separately monitored.
If an apportionment option is chosen, check, in addition to option (l), 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.
STEP 3
Identify the first calendar year in which the Acid Rain NOX compliance plan will apply. Beginning with the calendar year denoted at
Step 3, this Acid Rain NOX compliance plan will apply each calendar year that follows until (and if) a superseding Acid Rain NOX
compliance plan is submitted.

Acid Rain NOX Averaging Plan Instructions
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
Each unit in the averaging plan 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).
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 2
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.
STEP 3
Identify the first calendar year in which the Acid Rain NOX averaging plan will apply. Beginning with the calendar year denoted at Step
3, this Acid Rain NOX averaging plan will apply each calendar year that follows until (and if) a superseding Acid Rain NOX compliance
plan or averaging plan is submitted.

General Instructions
Submit one complete set of all forms with original signatures to the appropriate Title V permitting authority (for NOX Averaging
Plans, a copy of the plan must be submitted to each Title V permitting authority with jurisdiction over any of the units in the
plan) and one copy to U.S. EPA. Please note the different zip codes below.
