Do the Acid Rain SO 2 Regulations Apply to You?
II

-------
Overview
Q (the approximately 23 million tons of sulfur dioxide (SO 2 ) and
19 million tons of nitrogen oxides (NOr) emitted from all
sources in the United States in 1985, about 16 million tons of SO 2 and
seven million tons of NO were emitted by electric utility companies.
Emissions of SO 2 and NO are the primary causes of acid rain.
In order to reduce acid rain in the U.S. and Canada, Title IV of
the Clean Air Act Amendments of 1990 requires the Environmental
Protection Agency (EPA) to establish a program to reduce emissions,
called the Acid Rain Program. The overall goal of the Acid Rain
Program is to achieve significant environmental benefits through
reductions in SO 2 and NO emissions. To achieve this goal at the
lowest cost to society, the Program employs both traditional and
innovative market-based approaches for controlling air pollution. In
addition, the Program encourages energy efficiency and promotes
pollution prevention.
Title IV sets as its primary goal the reduction of annual SO 2
emissions by 10 million tons below 1980 levels. Approximately 85
percent of the reduction in emissions is to be achieved by electric
utilities. To achieve these SO 2 reductions, the law requires a two-phase
tightening of the restrictions placed on fossil fuel-fired power plants.
Phase I, which begins in 1995, requires 110 higher-emitting utility
plants in 21 eastern and midwestern states to meet an intermediate SO 2
emissions limitation. Phase II, which begins in the year 2000, tightens
the annual emissions limitation and expands coverage to most utility
units.
Under the Program, units are allocated “allowances” by EPA. An
allowance is a limited authorization to emit up to one ton of SO 2
during or after a specified calendar year. Once allowances are allo-
cated, owners or operators may use their allowances to cover emis-
sions, or they may trade their allowances to other units under a market-
able allowance program. EPA will keep track of the allowances held
by each unit by using the Allowance Tracking System (ATS).
I I I

-------
Do the Acid Rain SO 2 Regulations Apply to You?
Utility units that began operation prior to the passage of the Clean
Air Act Amendments (November 15, 1990) are allocated emission
allowances based on their historic fuel usage and emission rates
specified in Title IV and its implementing regulations. Most units
commencing operation from November 15, 1990, through December
31, 1995, will also be allocated allowances under Phase IL* The
National Allowance Data Base (NADB), developed by EPA, lists
utility units — existing and planned — as well as the information neces-
sary to allocate allowances to these units.
Units that are affected by the acid rain regulations are required to
limit SO 2 emissions to the number of allowances they hold. Some
utilities may benefit by selling their allowances while reducing their
emissions. Since allowances are fully transferable, these utilities may
choose to emit less than their allocated allowances and sell the differ-
ence to utilities that would benefit from buying allowances and emit-
ting more than their initial allocation. This trading achieves economic
efficiency while capping total SO 2 emissions nationwide.
* Certain other facilities may be allocated allowances, but they are not subject to
emissions limitations under Title IV. These allowances are allocated to provide
financial incentives for indirect reductions of SO 2 emissions. Small diesel refining
facilities are eligible for allocations based on fuel desulfurization, which will reduce
SO 2 emissions from diesel-burning vehicles (see 40 CFR 73 Subpart G). Also,
utilities using renewable energy or employing energy conservation measures may be
eligible for certain allowances (see 40 CFR 73 Subpart F).

Overview
In order to maintain a permanent cap on utility SO 2 emissions of
8.95 million tons per year, utility units that begin operation after 1995
generally are not allocated allowances. Affected units not allocated
allowances may not emit SO 2 unless they purchase allowances.
In any year that a source fails to hold sufficient allowances to
cover its emissions, excess emissions penalties will apply. Also, the
source must submit a plan to EPA that specifies how the excess SO 2
emissions will be offset, or it will have allowances deducted immedi-
ately from its unit account.
The Act also calls for a two million ton reduction in NO emis-
sions by the year 2000. A significant portion of this reduction will be
achieved by requiring coal-fired utility boilers to meet new NO
emissions requirements. A marketable allowance program is not part
of the NO reduction program.
What This Guide Will Tell You
This guide is designed to help utilities and other electricity gen-
erators determine whether they are affected by the SO 2 and monitoring
regulations of the Acid Rain Program. The flow chart on the inside
cover provides a quick-reference guide showing categories of units
that are affected by, eligible for exemption from, or unaffected by the
regulations. The document presents descriptions of these categories,
requirements for affected units, and requirements for obtaining exemp-
tions. Specific sections of the document are described below.
Section 1: Determining Applicability
This section outlines how to determine if a unit is affected by the
SO 2 and monitoring provisions of the Acid Rain Program. It describes
various types of units as defined by the Acid Rain Program and states
whether those types are affected by, may be eligible for an exemption
from, or are unaffected by the Acid Rain Program. This section also
outlines the information that needs to be included in a request for an
applicability determination from EPA.

Section 2: Requirements for Affected and
Exempted Units
A unit that becomes affected by the Program must meet several
initial and continuing requirements. This section outlines these re-
quirements and provides references for further information. This
section also provides compliance timelines for meeting Phase I, Phase
I I, and continuous emission monitoring (CEM) requirements, and it
lists permit deadlines and dates when units must hold allowances.

Regulations and Documents
Appendix A lists several acid rain regulations and informational
documents, including publication dates and dockets.

Examples
Appendix C presents several case studies demonstrating how to
determine whether the regulations affect certain utility units.
Appendix D: Selected List of Units Affected by
the Acid Rain Regulations
Appendix D provides lists of units affected by the acid rain regu-
lations. These lists were published in the Clean Air Act or in regula-
tions.

What This Guide Won’t Tell You
This document does not address Title IV NO control require-
ments, which establish new NO emissions limits for existing coal-
fired electric utility units.
This document also does not address requirements applicable to
unaffected units that voluntarily participate in the Acid Rain Program.
Sources of SO 2 that are not required to meet Title IV emissions limita-
tions may choose to “opt-in” to the Acid Rain Program. The Opt-In
Program encourages these sources to reduce emissions of SO 2 in
circumstances under which it will be less costly for them to do so than
it would be for an affected unit.
Note that many units are required to meet SO 2 emissions limita-
tions or control requirements under other programs, whether or not
they are affected by acid rain regulations. These other limitations may
be more stringent than the limitations under Title IV. Non-Title IV
requirements are not covered in this guidance.
For questions about the Acid Rain Program, or for more informa-
tion on the NO requirements or the Opt-In Program, please contact
the Acid Rain Hotline at (202) 233-9620. For questions or informa-
tion on other Federal or State clean air programs, please contact your
State air quality office (see Appendix B).

-------
Section 1
Determining Applicability
I n generaL the acid rain regulations for sulfur dioxide (SO 2 ) are appli-
cable to existing utility units serving a generator with nameplate capac-
ity of 25 megawatts of electricity (MWe) or greater and almost all new
utility units located in the 48 contiguous States and the District of Colum-
bia. For the purposes of the Acid Rain Program, the term “utility units”
includes units serving generators that supply electricity for sale, whether
wholesale or retail.
There are, however, applicability exceptions for certain types of units
and units meeting specific criteria. These units may be eligible for an
exemption or may be unaffected by the acid rain regulations. This section
provides the necessary information for determining whether a unit is
affected. Note that once a unit becomes affected, it remains affected for
the duration of the Program.
Section 1 is presented in three parts. The first part describes the
characteristics of affected units. The second part describes the characteris-
tics of units that may be exempted from certain acid rain regulations. The
third part describes six types of units that are unaffected by the regula-
tions. Following the descriptions of each of these unit types are checklists
of information to include in a request for an applicability determination. If
you do not know which type of unit you have, or if you have a unit that
may qualify as more than one type, be sure to submit the necessary mate-
rial for all potentially relevant categories.

Applying for an Applicability
Determination by EPA
EPA has adopted a procedure by which owners and operators of
any potentially affected unit may choose to ask EPA to determine
whether or not Title IV SO 2 requirements apply to their source. See 40
CFR 72.6(c). This procedure is optional ; EPA does not require any
owner or operator to request a determination of applicability. Those
sources that clearly fit into an unaffected or exempted category should
not feel compelled to request an applicability determination.
This procedure requires submittal of a written request, including
certain information about the unit. In response to that request, EPA
will determine if a unit is affected, based on information included in
the submittal. EPA will then write a letter stating that the unit is either
affected or unaffected. This response letter will constitute final agency
action in the absence of an administrative appeal and will be binding
upon the permitting authority administering the Acid Rain Program for
the unit (i.e., the State or EPA Region). EPA’s determination may be
appealed through the Acid Rain Appeals process. If the information
originally submitted by the unit was inadequate to make an applicabil-
ity determination, EPA may request additional data or write a letter
stating that EPA cannot make a determination based on the informa-
tion submitted.
2

-------
Determining Applicability
Affected Units
EPA has compiled a list of the sources of SO 2 emissions known
to be affected by the acid rain regulations. All of these “listed units,” Affected
which are discussed below, are Phase I or Phase II affected sources. A
list of these units is included in Appendix D. If a unit or source is listed
in the appendix, it is affected. Some of these units may be eligible for
exemptions from certain Acid Rain Program requirements, as dis-
cussed below. See 40 CUR 72.6(a).
Listed Units
Phase I requirements initially affect only the 263 units at the 110
power plants specifically listed in the Clean Air Act and provided in
Table 1 of 40 CFR 73.10 (see Exhibit I of Appendix D). Phase II
requirements affect a broader group of utility units. Tables 2 and 3 of
40 CUR 73.10 (see Exhibits 2 and 3 of Appendix D) list approximately
2,300 utility units affected by Phase I I requirements.
Additional units may become affected under Phase I if they are
either “substitution units” or “compensating units.” Utilities have
already notified EPA as to which units will be brought into Phase I in
this manner. Substitution units are existing units affected under Phase
LI that are designated under approved substitution plans and that accept
the emission reduction obligation of a unit required to comply with
Phase I. Compensating units are Phase II units that are designated
under approved reduced utilization plans and that generate electricity
to replace electricity historically generated by Phase I units.
Unlisted Units
The Appendix D listings do not include all units that are or may
become affected. Other potentially affected units include:
U Units not in the NADB,
U Units that are planned, and
U Units owned by industrial or commercial entities that sell
electricity.
3

-------
Do the Acid Rain SO: Regulations Apply to You?
If a unit is not listed in Appendix D, it may be affected by the acid
rain regulations only if it meets all three of the following conditions:*
I i The unit is a combustion device.
U The unit is fossil fuel-fifed.
U The unit supplies electricity for sale or serves an electricity..
generating device that supplies electricity for sale.
Definitions
Unit vs. Generator
A unit is a fossil fuel-fired combustion device, such as a boiler. A
generator is a device that produces electricity. A unit may be
subject to the acid rain regulations if it provides steam or is
capable of providing steam or hot air to a generator that produces
electricity. A generator itself is not affected by the acid rain
regulations. For the purposes of the Acid Rain Program, a com-
bined cycle turbine — a turbine with a heat recovery steam genera-
tor — will be treated as a single unit.
Combustion Devices
A combustion device is a device that initiates the chemical reac-
tion of fuel and oxygen with the addition of heat. In the case of a
combustion device that uses fossil fuels to produce electricity, the
combustion of fossil fuels causes the reaction of carbon and
hydrogen in the fuel with oxygen in the air to form carbon dioxide
and water vapor. Other substances, such as sulfur in the fuel and
nitrogen in the air, may also react with the oxygen and thereby
produce air pollutants.
Fossil Fuel-Fired
A source is “fossil fuel-fired” if it combusts any amount of fossil
fuel, no matter how small. The definition of fossil fuel includes
natural gas, petroleum, coal, and any form of solid, liquid, or
gaseous fuel derived from these materials, such as petroleum coke.
The definition of natural gas does not include landfill gas, digester
gas, or biomass.** Waste fuels, including anthracite cu lm and
bituminous coal waste, are also considered fossil fuels for the
purposes of the Acid Rain Program. A unit, by definition, is fossil
fuel-fired. Thus, a boiler fueled exclusively by fuels other than
fossil fuels is not a “unit” or “utility unit” under the regulations,
and therefore is not subject to the acid rain regulations.
* See 40 CFR 72.2 for the definition of “utility unit.”
* * See preamble to the final acid rain “core” rules, 58 FR 3596, January 11,
1993.
Examples of Combustion and
Non-Combustion Devices
combustion Devices
Combustion Turbine. A comb us-
tuon turbine uses air heated from
the combustion of fuel to spin the
turbine in a magnetic field, thus
creating electricity. Since it is a
device that uses combustion to
produce electricity directly, it is a
combustion device.
Boiler. A boiler is an enclosed de-
vice that combusts fuel to produce
and transfer heat to recirculating
water, steam, or any other me-
dium. Since it combusts fuel, it is
a combustion device.
Non-Combustion Devices
The! Coil. A fuel cell relies on a
electrochemical reaction of fue’
(usually pure hydrogen) with pure
oxygen to yield energy and water.
Since this reaction is not produced
by the addition of heat, it is not a
combustion device.
4

-------
Determining Applicability
• Supplies Electricity for Sale
Any unit that served a generator producing electricity for sale in
1985 or on or after November 15, 1990, is potentially affected by
the acid rain regulations. The sale may be wholesale or retail. The
“sale of electricity” is the sale of electrical output or capacity or
the sale of steam to a steam-electric generator that produces
electrical energy for sale.
Units that do not produce electricity or steam for sale are not
affected. Also, a unit that produces steam or heat rather than
electricity for sale is not affected so long as the purchaser of the
steam or heat does not produce electricity for sale. A unit that
produces limited amounts of electricity for sale may not be af-
fected if the unit’s combustion device is used primarily to produce
steam or heat. (See Co generation Unit, below.)
Even if a unit meets all three of the conditions discussed above, it
may be eligible for an exemption or qualify as one of six types of
unaffected units. Exemptions may be granted to new utility units
generating less than 25 MWe and using fuel with a sulfur, content less
than or equal to 0.05 percent, as well as to units that retire. The six
categories of unaffected units are existing simple combustion turbines,
existing small units, cogenerators, independent power production
facilities, qualifying facilities, and solid waste incinerators. The cat-
egories are described below in the sections Exempted Units and Unaf-
fected Units.
5

-------
Do the Acid Rain SO, Regulations Apply to You?
Exempted Units
Two categories of affected utility units may be eligible for ex-
emptions from many — but not all — of the acid rain regulations: small
new units burning clean fuels and retired units. These exempted units
must continue to meet certain continuing requirements of the Acid
Rain Program to remain exempted. Please refer to Section 2: Require-
ments for Affected and Exempted Units for a list of these requiremen 5
In order for a unit to be considered for an exemption. it must
submit an application to EPA . The Agency does not require eligible
units to apply for an exemption in cases where the owner of a unit does
not want the unit exempted. Units that do not obtain an exemption,
however, must fully comply with the Acid Rain Program require-
ments. If a unit decides to seek and is granted an exemption, it is not
eligible to join the Program on a voluntary basis as a substitution unit,
a compensating unit, or an opt-in unit.
Small New Units Burning Clean Fuels
A utility unit may be granted an exemption from acid rain regula-
tions if it meets all three of the following requirements:*
U The unit is a new unit (i.e., commenced commercial opera-
tion on or after November 15, 1990).
U The unit is a small unit (i.e., serves generator(s) with total
nameplate capacity of 25 MWe or less).
U The unit bums clean fuels (i.e., only fuels with sulfur content
of 0.05 percent or less by weight).
Although the statutory exemption for existing units that serve
generators with nameplate capacities of 25 MWe or less does not sum
the nameplate capacities of all the generators served by the unit, the
exemption for new units requires that the total nameplate capacity
served by the unit be 25 MWe or less. For example, boilers headered
to more than one generator (multi-header units) will be treated as
serving all generators to which they are headered, regardless of the
steam capacity of the boiler.
* See 40 CFR 72.7.
6

-------
Determining Applicability
A small, ne w unit that is granted an exemption will have to forfeit
any allowances it received or was to receive as an initial allocation for
all years for which the exemption is granted. Also, if the unit gains an
exemption, it must comply with the acid rain regulations for all years
prior to January 1 of the year after it is issued the exemption. For
information on applying for a new unit exemption see Section 2:
Requirements for Affected and Exempted Units.
Definitions
Commence Commercial Operation
A unit “commences commercial operation” when it begins to
generate electricity for sale, including the sale of test generation.
The National Allowance Data Base (NADB Version 2.11) in-
cludes the boiler on-line date and generator on-line date (month
and year). For units in the NADB that commenced commercial
operation by December 1992, the boiler on-line date in the NADB
will be used as the date the unit commenced commercial opera-
tion. If a unit is not listed in the NADB or if a unit commenced
commercial operation after December 1992, the first commercial
on-hne date will be determined in accordance with standards used
by the Energy Information Administration (E IA). In general,
generator first-electricity dates are reported to the U.S. Department
of Energy (DOE), Energy Information Administration on Form
EIA 86O,* and boiler first-fuel consumption is reported on Form
E1A 767.*
Each unit should have only one date of commencement of com-
mercial operation, even if the unit is relocated or restarted after
retirement. However, a unit that was substantially modified before
November 15, 1990, may be treated as a unique unit with a new
commencement of commercial operation date.
Nameplate Capacity
“Nameplate capacity” is a measure of the capacity of a generator.
For a unit listed in the NADB, the nameplate capacity of a genera-
tor is defined as the capacity listed for the generator in the NADB.
If a unit is not listed in the NADB, the nameplate capacity will be
determined in accordance with the DOE standards using Form
EIA-860. Generator nameplate capacity as defined on Form E IA-
860 is the full-load continuous rating of a generator, prime mover,
or other electric power production equipment under specific
conditions as designated by the manufacturer. Installed generator
nameplate rating is usually indicated on the nameplate physically
attached to the generator. If more than one capacity appears on the
nameplate, the highest capacity is reported on Form EIA-860.
* A description of Forms EIA-860 and EJA-767 is provided in the Glosswy.
Example of New Commercial
Commencement
The Tidd plant in Ohio was retired
pnor to 1985. The plant was sub-
stantially modified and repowered
through a clean coal Technology
project and began operation again
in October, 1990. Therefore, EPA
assigned this plant a commenced
commercial operation date of
October 1990.

Burns Clean Fuel
Clean fuels are fuels with sulfur content of 0.05 percent or less by
weight. All natural gas, including most “sour” gases, meets this
standard. On-road diesel fuel meeting the new requirements of the
Clean Air Act (Section 211(i)) will also meet this standard. A unit
obtaining an exemption under this provision must test petroleum
or petroleum products and gaseous fuels, other than natural gas,
according to the appropriate ASTM methods to assure compliance
starting on the first day the exemption takes effect .
Retired Units
A utility unit may be granted an exemption from the acid rain
regulations if it retires before the issuance (or renewal) of its Phase H
acid rain permit (see 40 CFR 72.8). These “retired” units must docu-
ment the actual or expected date of retirement as well as any actions
that have been taken to retire the unit and to prevent any further emis-
sions of SO 2 and NOR. If the unit gains an exemption, it must comply
with the acid rain regulations until January 1 of the year after it is
issued the exemption. Therefore, to avoid installation and testing of
continuous emission monitoring (CEM) systems required by the Acid
Rain Program, a unit must apply for this exemption prior to January 1,
1995.
If a retired unit is to resume operation, its Designated Representa-
tive must submit an acid rain permit application not less than 24
months prior to January 1, 2000 or the date the unit is to resume
operation, whichever is later.
For information on applying for a retired unit exemption see
Section 2: Requirements for Affected and Exempted Units.

Determining Applicability
Unaffected Units
Some sources of SO 2 emissions that generate electricity for sale
or provide steam or heat for electricity generation are not subject to
emissions limitations under Title IV. The following six types of elec-.
tricity generat1ng units are not affected by the regulations under
certain conditions:
tJ Existing Simple Combustion Turbines, under 40 CFR
72.6(b)( 1).
( Existing Small Units, under 40 CFR 72.6(b)(2).
D Cogenerators, under 40 CFR 72.6(b)(4).
Li Independent Power Production Facilities, under 40 CFR
72.6(b)(6).
U Qualifying Facilities, under 40 CFR 72.6(b)(5).
Li Solid Waste Incinerators, under 40 CFR 72.6(b)(7).
Units in each category must meet requirements specific to that
category to be unaffected. These requirements are discussed below. A
unit need only qualify as unaffected under one of these categories in
order to be unaffected. In order to remain unaffected, these units must
meet a set of “continuing requirements,” also discussed below.
If a facility is unaffected under more than one provision, it will
remain unaffected until it loses its unaffected status for all appropriate
provisions. For example, if a unit is unaffected as both an IPP and a
QF, then it will remain unaffected if it loses its status as unaffected IPP
but retains its status as an unaffected QF.
The Acid Rain Program does not require an unaffected unit to
submit proof of its status. However, units may be required to provide
documentation supporting their claim of unaffected status, if requested
by EPA or the State or Regional permitting authority. Unaffected units
may become affected under certain operating or construction condi-
tions. It is the duty of the unit’s owner and operator to meet the re-
quirements of the Acid Rain Program if the unit becomes affected.
Also, unaffected units may be eligible to opt-in to the Program, as
discussed above in What This Guide Won’t Tell You.

(1) Existing Simple Combustion Turbines
A utility unit is not affected by the acid rain regulations if it meets
both of the following conditions:
U The unit is a simple combustion turbine.
U The unit is an existing unit (i.e., commenced commercial
operation before November 15, 1990).
Definitions
Simple Combustion Turbine
For the purposes of the acid rain regulations, a “simple combustion
turbine” is defined to include a combined cycle unit that did not
use auxiliary firing in 1985 through 1987 and will not use auxil-
iary firing at any time after November 15, 1990. A combined cycle
unit that uses auxiliary firing during these periods does not qualify
as a simple combustion turbine.
Combined Cycle Unit
In a combustion turbine, air heated from the combustion of fuel
causes a turbine to spin in a magnetic field, which, in turn, creates
electricity. If the hot air exiting the turbine is captured through a
heat recovery steam generator or waste heat boiler, the turbine is a
combined cycle unit.
Auxiliary Firing
In some combined cycle units, additional fuel is burned in a duct
or in a heat recovery steam generator in order to enhance the
production of steam. This is called auxiliary, or supplemental,
firing.
Continuing Requirements
If a simple combustion turbine installs and uses auxiliary firing, it
will become an affected unit. To remain unaffected, a simple combus-
tion turbine may not add or begin using auxiliary firing.
Examples of Combustion
Turbines
Example 1: Two simple turbines
feed a common header to a single
heat recovery steam generator (i.e.,
together they constitute a com-
bined cycle unit) that has auxiliary
firing. Neither turbine qualifies as
a simple ‘combustion turbine.
Example 2: A combustion turbine
serves a heat recovery generator
that installed a duct burner in 1983.
Due to poor efficiency in the duct
burner, the duct burner is not uti-
lized after 1984, although not re-
moved. The turbine is a “simple
combustion turbine” as defined.

Determining Applicability
(2) Ex 5th g iu vL g
Than or Eqi n T©
A utility unit is not affected if it meets both of the following
requiremefl
U The unit serves a small generator (i.e., the largest generator
served by the unit, on or after November 15, 1990, has a
nameplate capacity less than or equal to 25 MWe).
U The unit is an existing unit (i.e., commenced commercial
operation before November 15, 1990).
The term “serve” means either providing steam or being capable
of providing steam to a generator. A unit on cold standby is considered
capable of providing steam. The only units EPA can confirm through
DOEIEIA data as not serving a generator are those units that are
reported as. retired.
Generators listed in the NADB are defined to have the nameplate
capacity listed in the NADB. The regulations are not designed to
penalize units that improve efficiency without increasing emissions.
Thus, if a generator listed in the NADB is modified to produce over 25
MWe capacity because of significant improvements in turbine effi-
ciency only, the units serving this generator do not become affected.
For example, a boiler that in 1988 served a generator of 22 MWe
nameplate capacity, as listed in the NADB, may retain its unaffected
status if that generator is renovated to increase its output capacity from
the same steam input. Unaffected units are required to submit informa-
tion on improved turbine efficiency only if specifically requested by
EPA or the State or Regional permitting authority.
However, if a boiler served a generator of 22 MWe nameplate•
capacity before November 15, 1990, that is replaced with a new
generator of greater than 25 MWe nameplate capacity after November
15, 1990, then that boiler will be affected. Also, if a new generator is
hnked to that boiler and if that generator has a nameplate capacity of
greater than 25 MWe, the boiler will be affected. On the other hand, if
a boiler that serves a generator of 22 MWe nameplate capacity is
hnked to a new generator of 5 MWe nameplate capacity, the boiler
will not be affected because it is not serving any individual generator
of greater than 25 MWe nameplate capacity.
SubmIt the fol owIrig

V The nameplate capacity of all
generators served by the unit
on or after November 15, 1990.
/ The date the unit commenced

Conthuj g R qemetnt
If after November 15, 1990, the existing utility unit serves a
generator with a nameplate capacity of greater than 25 MWe, it will
become an affected unit.
Examples o ExistIng limits
Example 1: Unaffected Unit. In
1985, a boiler served a 5 MWe
generator and a 45 MWe generator
that were used to produce electric-
ity for sale. In 1988, the 45 MWe
generator was retired. The boiler is
not affected because, as of No-
vember 15, 1990, it did not serve
a generator with nameplate capac-
ity greater than 25 MWe.
Example 2: Affected Unit. Three
boilers, two consuming coal and
one burning natural gas, com-
menced commercial operation in
1967. The boilers feed a common
header that serves two generators,
one of 11 MWe nameplate capacity
and one of 26 MWe nameplate
capacity, that are used to produce
electricity for sale. All three boilers
are affected because one of the
generators has a nameplate ca-
pacity greater than 25 MWe. Even
if no one boiler could produce
enough steam to feed the 26 MWe
generator, all boilers are affected.

(3) Cogeneration Units
A cogeneration unit (or cogenerator) is a unit that produces steam
or heat both for direct use and to run an electricity generator.
Definition
Cogeneratlon Unit
A cogeneration unit is a unit that produces electric energy and
various forms of useful thermal energy (such as heat or steam) for
heating or cooling purposes by using the waste heat of one process
as the energy input into a subsequent process. For example, a unit
that produces electricity and then uses the waste heat of that
process as energy to run a process that cools another unit is a
cogenerator.
The statute provides that some cogenerators may not be affected
by the Title IV regulations. Although many cogenerators were con-
structed primarily to serve a specific industrial need, they often sell
excess electricity to local utilities for distribution to the utilities’
customers. Because only “utility units” (i.e., units that are used to
produce electricity for sale) are affected by Title IV regulations, EPA
makes a distinction between cogenerators operating to sell electricity
and those operating primarily for self-generation (e.g., boilers for in-
house use that do not sell electricity).* The key factors are the portion
of “potential electrical output capacity” (a capacity-equivalent of the
boiler) sold and the actual MWe-hrs of electrical output sold.
Which Cogenerators are Unaffected?
For cogeneration units that commenced construction on or before
November 15, 1990, a unit is unaffected if it was constructed for the
purpose of supplying less than or equal to one third of its potential
electrical output capacity or less than or equal to 219,000 MWe-hrs of
annual electrical output.** Documents that can be used for determin-
ing the purpose of construction include permitting applications, con-
struction contracts, and original plant diagrams. In the absence of
information regarding the purpose of construction (often the case with
very old plants), EPA will assume that actual operations from 1985
through 1987 represent that purpose. If the unit began operations after
1985, EPA will use the operational data for the first three calendar
years of operation to make the determination of purpose.
* A cogenerator also may be unaffected by the regulations because it is a qualify-
ing facility or an independent power production facility. These types of facilities are
discussed below.
* 1 219,000 MWe-hours is equal to 25 MWe multiplied by 8,760 hours, the number
of hours in a year.
12

-------
Determining Applicability
Potential electrical output capacity is the MWe capacity rating for
the unit, which is equal to 33 percent of the maximum design heat
input capacity of the steam generating unit for boilers and simple
combustion turbines. The potential electrical output Capacity for these
units is calculated using the following equation:*
(Maximum Design Heat Input (mniBtu/hr)) X (1,000,000 Btu/l mmBtu)
x (33%) x (1 kw-hr/3,413 Btu) x (1 MWe/l,000 kw) = MWe
For multi-headered boilers, the potential electrical output capacity
for the entire source is equal to the sum of the potential electrical
output capacities for each boiler. To compare an individual boiler’s
potential electrical output capacity to the generator capacity (in MWe),
determine the total generator nameplate capacity (if there are multiple
generators) and divide by the boiler’s proportional share of steam
based on the unit’s potential electrical output capacity (see example).
EPA will work with the unit to determine the appropriate sharing of
output capacity.
For combined cycle combustion turbines, the Agency will con-
sider information as to actual efficiency of a specific system. EPA
understands that many combined cycle combustion turbines operate at
approximately 50 percent efficiency. Thus, to calculate the actual
electrical output, the maximum fuel flow (in mmBtu/hr as an aggre-
gate value for the turbine and any supplemental or auxiliary burners)
multiplied by 50 percent, should be substituted for the first term in the
equation presented above:
(Maximum Fuel Flow (mmBtu/hr)) x (1,000,000 Btull mmBtu)
x (50%) x (lkw-hr/3,4l3 Btu) x (I MWe/l,000 kw) = MWe
For complex multi-headered combined cycle units, the owner/
operator may request to use a formula that more accurately estimates
the potential electrical output capacity for the unit(s).
To determine whether the unit is affected, compare the potential
electrical output capacity to the nameplate capacity of the generator. If
the nameplate capacity of the generator is more than one third of the
potential electrical output capacity, then the annual sales must be
evaluated. If the annual electrical sales exceed 219,000 MWe-hrs, the
unit will be affected.
The calculation of actual electrical output should incorporate
mdirect steam supplied to a steam-electric generator that will produce
electrical energy for sale. Convert the Btus of steam sold to MWe-hrs
based on the equation for potential electrical output capacity above
assunung 33 percent efficiency. Add the MWe-hrs of steam to the
direct MWe-hrs supplied for a total.
Example of Potential
Electrical Output Capacity
A boiler has a maximum design
heat input capacityof 340 mmBtu/
hr. Using the conversion equation,
(340,000,000 Btu/hr) x (1/3) x
(1 kw-hr/3,413 Btu) x (1 MWe/
1,000 kw),
this boiler has a potential electri-
cal output capacity of 33.2 MWe.
Example of Actual Electrical
Output from a Cogenerator
Providing Steam to a
Generator That Provides
Electricity
A cogeneration unit provides
175,000 MWe-hrs of electricity to
the grid and 100 mmBtufhr of
steam to a second generator that
sells electricity.
(100,000,000 Btu/hr) x (1/3) x
(1 kw-hrf 3,413 Btu) x (1 MWe/
1,000kw)x8,76Ohrs/yr=
85,555 MWe-hrs
Thus, the total electricity sold is
175,000 + 85,555 = 260,555
MWe-hrs.

Example of Cogenerator DetermInations
Situation I:
Boiler 1 (1,024 mmBtu/hr) serves Generator A (50 MWe nameplate)
Boiler 2 (4,100 mmBtu/hr) serves Generator B (50 MWe nameplate)
To calculate Potential Electrical Output Capacity:
Boiler I = (1,024,000,000 Btu/hr) x (33%) x (1 kw-hr/3,413 Btu) x (1 MWe/1,000 kw)
= 100 MWe
Boiler 2 = (4,100,000,000 Btu/hr) x (33%) x (1 kw-hr/3,413 Btu) x (1 MWe/1,000 kw)
= 400 MWe
First, compare nameplate capacity of generator served to potential electrical output capacity of boiler:
Boiler 1 serves 50 MWe/100 MWe = 50% of potential capacity
Boiler 2 serves 50 MWe/400 MWe = 12.2% (Boiler 2 is unaffected because 12.2% is less than 33%.)
Because Boiler 1 serves over 50% of potential electrical output capacity, calculate the actual electrical output at 1/3
potential electrical output capacity for Boiler I only:
Boiler 1 = 1/3 x 100 MWe x 8,760 hr/year = 292,000 MWe-hrs
If Generator A sells less than this every year, Boiler 1 is unaffected as well.
Situation II:
If Boilers I and 2 are multi-headered to Generators A and B, we compare the proportion of electrical output to total
nameplate capacity.
Boiler 1 serves 100 MWe/500 MWe (total unit capacity) x 100 MWe (total generator nameplate) = 20 MWe
= 20% of its Potential Electrical Output Capacity
Boiler 2 serves 400 MWe/500MWe x 100 MWe = 80 MWe
= 20% of its Potential Electrical Output Capacity
(Result - both boilers are unaffected because both produce less than 33% of potential capacity.)

(4) Independent Power Production Facilities
and (5) Qualifying Facilities
Certain independent power production facilities and qualifying
facilities are not affected by the Acid Rain Program regulations.
Definition
Independent Power Production Facility (1PP)
An “independent power production facility” (IPP) is a source
developed, usually by private investors, to serve as a wholesaler of
power to a public utility. The Public Utility Regulatory Policies
Act of 1978 (PURPA) provided a loose framework for the IPP
industry. IPPs may offer utilities energy at lower cost and lesser
risk than building electric plants or purchasing power from other
utilities. LPPs and utilities negotiate preliminary power commit-
ments, which often include 20- or 30-year terms. After obtaining
the commitment, the project developers negotiate fuel supply,
transportation contracts, construction contracts, site lease, and
other project specifications. For these projects, lenders have
recourse only to the assets and cash flows associated with a
specific project and not to a parent company or partner companies
that provide equity or other assurances. This type of financing is
called “nonrecourse project financing.”
In order for an IPP project to be unaffected by the Title IV regula-
tons, it must meet the following requirements:
U The project must be nonrecourse project financed.
U The project must sell at least 80 percent of the power gener-
ated at wholesale.
o The project must have no more than 50 percent direct public
utility ownership. This does not preclude indirect ownership
of an IPP by a public utility through its unregulated subsid-
iaries or affiliates.
16

Determining Applicability
Definition
Qualifying Facility (QF)
A “qualifying facility” (QF) is a qualifying cogeneration facility or
qualifying small power production facility as defined under
PURPA. Small power production facilities are facilities generating
not more than 80 MWe that employ renewable resources — such as
water power, solar energy, wind energy, geothermal energy,
biomass, or waste — as a primary fuel.
In order for a cogeneration facility to be a qualifying facility, it
must meet the following requirements:
0 No electric utility or public utility holding company or any
organization* owned by either may own more than 50
percent of equity interest in the facility.
0 The unit must meet operating and efficiency standards
specified in 18 CFR 292.205.
Many cogenerators meet these requirements.
In order for a small power production facility to be a qualifying
facility, it must meet all three of the following requirements:
0 The unit must use fuel that is composed of more than 75
percent biomass, waste, renewable resources, geothermal
resources, or some combination of the above.
U Fossil fuels must compose less than 25 percent of the fuel
used by the facility.
U No electric utility or public utility holding company or any
organization* owned by either may own more than 50
percent of equity interest in the facility.
As few small power production facilities meet QF fuel require-
ments, most QFs are qualifying cogeneration facilities.**
In some instances, a qualifying small power production facility
may be unaffected under the provisions applicable to solid waste
incinerators. Qualifying cogeneration facilities may also be unaffected
under the cogenerator provisions, but qualifying cogeneration facilities
need only satisfy the provisions for any one of the six types of electric-
ity-generating units described (see 40 CFR 72.6(b)) in order to be
unaffected.
* Organization as defined as “person” in the Federal Power Act, Section 3. This
definition includes municipalities as well as other individuals and organizations.
** See 18 CFR 292.204.

Do the Acid Rain SO, Regulations Apply to You 2
Example of Whether a Unit Is
Affected based on Total
Planned Net Output Capacity
Example .1: An IPP had qualifying
power purchase commitments
demonstrating that 100 MWe of
capacity was planned and that 17%
of its total planned net output ca-
pacity would be sold. The facility
commences commercial operation
with 110 MWe capacity. As such,
all units at the facility are unaf-
fected (assuming all other require-
ments are met) If an additional
boiler-generator pair, with the same
emission rates as the rest of the
facility, is added for more than 20
MWe additional capacity (bringing
the total capacity of the facility to
over 130 MWe), this new boiler
Nould be affected.
Example 2: An IPP has a power
purchase commitment in 1989 for
SO MWe, but the power purchase
:ommitment did not list planned
capacity. In 1989, the IPP signed a
construction contract for two coal-
ired boilers and generators, with
?ach generator rated at 50 MWe
capacity. In 1992, the IPP signed
3nother power purchase commit-
nent for 70 MWe and contracted
construction of another 50 MWe
lenerator to be served by a gas-
red boiler. The entire facility com-
nences commercial operation in
1996. From these facts, the total
lanned net output capacity of the
acilityon November15, 1990 was
100 MWe. However, part of the
acuity is affected by the Acid Rain
‘rogram because, as constructed,
the facility’s total installed net out-
‘ut capacity is greater than 130%
ifthat planned. Because the ernus-
don rates of SO 2 and NO of the
coal-fired and gas-fired boilers are
lifferent, EPA may choose which
ioiler is affected. Only one boiler,
however, will be affected.
While EPA’s rules provide the limit on ownership interest for
unaffected independent power production facilities, Federal Energy
Regulatory Commission (FERC) rules established under PURPA limit
ownership interests for QFs. FERC rules generally do not allow a
partially or wholly owned subsidiary of an electric utility or electric
utility holding company to have more than 50 percent ownership in a
qualifying facility. *
IPPs and QFs may be regulated under both Title IV and Tide I II.
For example, a unit burning waste fuels for more than 20 percent of its
fuel may be regulated as both a solid waste incinerator under Title III
and as an affected unit under Tide IV. This would occur if “waste
fuel,” which is considered a “fossil fuel” under the Acid Rain Pro-
gram, is considered also to be a “refuse-derived fuel” under the solid
waste incinerator provisions of Title Ill**
Which IPPs and QFS are Unaffected?
In order for an IPP or a QF to be unaffected, it must meet all
three of the following requirements:
0 The facility must meet the definition of an IPP or a QF as
described above.
U The facility must have, as of November 15, 1990, a “qualify-
ing power purchase commitment” to sell at least 15 percent
of its total planned net output capacity.
U The total installed net output capacity of the facility must not
exceed 130 percent of the total planned net output capacity.
The total planned net output capacity of a facility is established
by reference to the power purchase commitment in place as of Novem-
ber 15, 1990 or by reference to other contemporaneous documents,
such as submissions to a State environmental authority or construction
contracts.
For example, a facility with a planned net output capacity of 100
MWe must have, as of November 15, 1990, a qualifying power pur-
chase commitment of at least 15 MWe. If the facility has more than
one qualifying power purchase commitment, the sum of the committed
capacities is compared to the planned capacity (e.g., a facility planned
for 200 MWe could have two qualifying power purchase commitments
for 15 MWe each and be unaffected).
* See 18 CFR 292.206.

(6) Waste e ito rs
If a unit is a “solid waste incinerator” that produces electricity for
sale or provides steam or heat for electricity generation, it may be
affected by the acid rain regu1ations . A solid waste incinerator is a unit
that burns nonhazardous solid wastes from commercial or industrial
establishments or the general public (e.g., residences). For example, a
QF that bums municipal solid waste is a solid waste incinerator and
may be unaffected under this provision if it meets the requirements
discussed belOw.
The definition of a solid waste incinerator does not include the
following categories of facilities:
c i Incinerators of hazardous wastes;
Materials recovery facilities;”
ci Qualifying facilities that burn homogeneous wastes (except
for. refuse-derived fuel), including tires and used oil; and
ci Air curtain incinerators burning wood wastes, yard wastes,
and clean lumber.
Which So d Waste linchierators a è Unaffected?
Solid waste incinerators burning less than 20 percent fossil fuels
(on a Btu, or heat input, basis) are not affected by the acid rain regula-
tions. The unit must meet this requirement on average for the three
years from 1985 to 1987 or for the first three calendar years of opera-
tion if the unit began operation after 1985. Solid waste incinerators
may also be subject to other control, technology-based requirements
under the Clean Air Act.

An unaffected solid waste incinerator must continue to combust
less than 20 percent fossil fuels (on a Btu basis) on three-calendar-year
rolling average for any period after November 15, 1990, in order to
stay unaffected. Fuel consumption for most units is reported to the
Department of Energy, Energy Information Administration, in’Btus,

, unit must comply with acid rain regulations, including
t . holçling allowances sufficient to cover its annual SO 2 emissions,
acid rain permit (which is part of the unit’s general air
p rrnit), having a Designated Representative (DR), and installing and
koperating ystems that continuously monitor emissions of SO 2 , NOR,
and other related pollutants These requirements are discussed below
Th onl jway an affected unit may avoid the full requirements of
the Acid Rain Program is by qualifying for an “exemption,” as de-
scribed in S ctzon 1 Even if a unit is awarded an exemption, it is
subject to certain minimum requirements
Inlorthation presented in this section is provided as summary
,guidance for the Acid Rain Program requirements This section also
pr wides corhphance timehnes for Phase I and Phase II of the Program
as well as fcir continuous emission monitoring (CEM) For more

Do the Acid Rain SO, Regulations Apply to You
Continuous Emission Monitoring
Each affected unit must continuously measure and record its
emissions of SO 2 , NOR. and carbon dioxide, as well as volumetric
flow, opacity, and diluent gas, unless otherwise specified in regula-
tions at 40 CFR 75. Most units must be equipped with a continuous
emission monitoring (CEM) system. CEM systems are critical to the
Acid Rain Program for several reasons:
C) They ensure compliance with the emissions limitations.
C) They instill confidence in allowance transactions by certify-
ing the existence and quantity of the commodity being
traded.
U They track the progress of the Program.
The CEM rule (40 CFR 75) also contains provisions for initial
equipment certification procedures, periodic quality assurance and
quality control procedures, recordkeeping and reporting, and proce-
dures for filling in missing data periods. Affected units are required to
report emissions data to EPA ’s Emission Tracking System on a quar-
terly basis. Please refer to the compliance timeline table at the end of
this section for dates by which installation and certification testing of
CEM systems must be complete.
Holding Allowances
Each affected unit must hold an allowance for every ton of sulfur
dioxide emitted during a calendar year. To support this requirement,
EPA has developed an electronic recordkeeping and notification
system, called the Allowance Tracking System (ATS), to keep track of
allowance transactions and the status of allowance accounts. ATS will
provide the official tally of allowances by which EPA will determine
compliance with the emissions limitations.
An ATS account has been established for each unit listed in
Exhibits 1, 2, and 3 of Appendix D. EPA will open an account for
affected units not listed in Exhibits 1, 2, or 3 of Appendix D upon
submittal of Certificate of Representation for the source identifying a
Designated Representative. Once EPA receives a Certificate of Repre-
sentation, it will establish an account for each unit at the source. This
certificate must be submitted to EPA with or-prior to the permit appli-
cation for the unit. Any other party interested in participating in the
trading system may open an ATS account by submitting a general
account application to EPA.
What Are the Monitoring
Renuirements?
The owner or operator of an
affected unit must install CEM
system on the unit and pro-
vide emission reports to EPA
unless otherwise specified in
the regulations. CEM systems
include the following:
O An SO 2 pollutant concen-
tration monitor
O A NO pollutant concentra-
tion monitor
O A volumetric flow monitor
O An opacity monitor
o A diluent gas (oxygen or
C0 2 ) monitor that monitors
CO 2
O A data acquisition and han-
dling system (computer-
based) for recording and
performing calculations
with the data.
Refer to 40 CFR 75 for excep-
tions and other additional re-
quirements.
22

-------
Requirements for Affected and Exempted Units
The ATS also provides the allowance market with a record of
who is holding allowances, the date of allowance transfers, and the
allowances transferred. The ATS does not, however, record the price
or other terms associated with allowance trades; such information is
better collected and reported by the private sector through established
exchanges or other trade information brokers.
Each affected unit must hold sufficient allowances in its account
by January 30 (or, if January 30 is not a business day, the first business
day thereafter) to cover its emissions for the previous year. For ex-
ample, a new affected unit that commences commercial operation
during 2002 must hold sufficient allowances in its account to cover its
emissions of SO 2 during the year 2002 by January 30, 2003.
If a unit emits more tons of SO 2 than allowances it holds in its
account, the additional tons of SO 2 emitted and not covered by allow-
ances are called “excess emissions.” Under the Acid Rain Program, if a
unit has excess emissions, it must pay $2,000 (adjusted by the Con-
sumer Price Index) per ton of excess emissions and submit an offset
plan. The offset plan tells how many allowances are to be deducted
from the unit’s allowance account for future years to offset the previ-
ous year’s excess emissions. Thus, a unit must make up for all excess
emissions.
Designated Representatives
Each source must appoint one individual, the Designated Repre-
sentative, to represent the owners and operators of the source in all
matters relating to the holding and disposal of allowances for its
affected or exempted units. The Designated Representative is also
responsible for all submissions pertaining to permits, compliance
plans, emission monitoring reports, offset plans, compliance certifica-
tion, and other required information. To specify a Designated Repre-
sentative, complete the Certificate of Representation. The Certificate
of Representa1 ion form and instruction are provided in Appendix E.
Permitting
The Designated Representative for each affected source is re-
quired to file a permit application for the source and a compliance plan
for each affected or exempted unit at the source with the permitting
authority. The permitting authority is either the approved State permit-
ting authority or EPA. Contact the EPA Regional office to determine
the appropriate permitting authority for your unit(s). See Appendix B.
For exempted units, the exemption itself serves as a permit for the
unit. Both permits (for affected units) and exemptions (for exempted
units) must be renewed every five years.
What information Is
Contained in ATS
Accounts?
ATS accounts include the
name and address of the au-
thorized account representa-
tive (the official contact per-
son for the account); the
allowances in current and fu-
ture subaccounts; and a record
of allowance transfers to and
from the account. Information
in the ATS accounts is avail-
able to the public.
What information Must
Be included In Permit
Applications?
The source must complete
standard forms when applying
for an acid rain permit. The
forms request information
about the Designated Repre-
sentative, general plant infor-
mation, specific unit informa-
tion, and a compliance plan
for each affected unit. Forms
can be obtained from a per-
mitting authority. Please refer
to Appendix B.

-------
Do the Acid Rain SO, Regulations Apply to You?
The Acid Rain Program operating permit details the specific
program requirements and compliance options chosen by each source.
The permits and compliance plans aim to provide flexibility, which is
a goal of the Acid Rain Program as a whole; permits and compliance
plans are designed to complement the marketable allowance program
and foster trading. The permits and compliance plans also let sources
fashion a compliance strategy tailored to their individual needs.
The permit stipulates the initial annual allowance allocation for
each affected unit at a source. The permit application must certify that
each unit’s account will hold a sufficient number of allowances to
cover the unit’s SO 2 emissions for the year and that the unit will
comply with the applicable NO limit. In addition, the compliance
plans may specify alternative measures that will be taken to ensure
compliance. Permits are subject to public comment before approval.
Applying for an Exemption
Small, new units burning clean fuel and retired units that meet the
requirements stated in Section 1: Exempted Units can apply for an
exemption with the permitting authority. The Designated Representa-
tive for a small, new unit can apply for an exemption. Any allowances
allocated to a small, new unit must be surrendered for any year for
which the unit is exempted.
For retired units, the Designated Representative must submit a
petition for written exemption to the permitting authority on or before
(1) the deadline for submitting an acid rain permit application for
Phase H, or (2) if the unit has a Phase II acid rain permit, the deadline
for reapplying for that permit. The petition for written exemption must
contain:
I ] Identification of the unit,
U The applicable deadline for submission,
U The actual or expected date of retirement of the unit,
U A description of any actions that have been or will be taken
with regard to the retirement of the unit, and
U The following statement: “I certify that this unit [ ‘is’ or ‘will
be’ as applicable] permanently retired on the date specified
in this petition and will not emit any sulfur dioxide or nitro-
gen oxides after such date.”
This information must be supplied to the permitting authority on forms
as stipulated by the permitting authority.
24

-------
Requirements for Affected and Exempted Units
A retired unit obtaining an exemption must comply with the monitor-
ing requirements, as previously discussed, unless an exemption from these
requirements is obtained from the permitting authority. Units that will be
permanently retired prior to January 1, 1995 can be exempted from install-
ing and certifying a continuous emission monitoring system if the Desig-
nated Representative completes a written exemption petition prior to the
deadline for completion of certification tests for the continuous emission
or opacity monitoring systems. Retired units will retain any allowances
they are allocated in 40 CFR 73. An exempted unit shall not resume
operation unless the Designated Representative submits an acid rain
permit application for the unit not less than 24 months prior to the later of
January 1, 2000 or the date the unit is to resume operation. A unit must
comply with all of the acid rain regulations as of the earlier of the date an
exemption expires or the date a permit application is submitted (or re-
quired to be submitted).
The exemption of a small, new unit or a retired unit will take effect
beginning January 1 of the year following the issuance of the written
exemption.
Compliance Timelines
The following table indicates when a specific type of unit becomes
affected by the acid rain regulations, the deadline for that unit to apply for
an acid rain permit, the deadline for completing continuous emission and
opacity monitoring compliance testing, and the first date on which a unit is
required to hold allowances.

Glossary
Many of these definitions have been paraphrased from the definitions included in the Code of
Federal Regulations (40 CFR 72.2). References have been provided where applicable. The Code of
Federal Regulations also contains additional definitions relating to the Acid Rain Program that are
not included here.
Acid Rain Permit: The acid rain portion of a source’s operating permit. It is the legally binding
document specifying acid rain requirements applicable to an affected source. See 40 CFR 72.2.
Affected Unit: A unit that is subject to any acid rain emissions reduction requirement or acid rain
emissions limitation. See 40 CFR 72.2.
Allowance: Under the Acid Rain Program, an authorization to emit up to one ton of sulfur dioxide
during or after a specified calendar year.
Auxiliary Firing: The use of fuel in addition to the primary fuel supply to enhance the production
of steam. For example, a cogeneration facility in which the energy input to the facility is first
used to produce power, and the waste heat is used to provide useful steam where additional
natural gas firing is used to boost the steam/thermal process. This addition of natural gas is
called auxiliary firing. See 18 CFR 292.202.
Boiler: An enclosed fossil or other fuel-fired combustion device used to produce and transfer heat
to recirculating water, steam, or any other medium. See 40 CFR 72.2.
Certifying Official: The person required to sign a request for an applicability determination by
EPA. For a corporation, this should be the president, secretary, treasurer, or vice-president in
charge of a principal business function, or other person who performs similar policy or deci-
sion-making functions. For a partnership or sole proprietorship, this should be a general partner
or the proprietor.
Clean Fuels: Fuels with sulfur content of 0.05 percent or less by weight.
Cogeneration: The combined production of power and useful heat that uses the reject heat of one
process as the energy input into a subsequent process. These processes may be for industrial,
commercial, heating, or cooling purposes. See 18 CFR 292.202.
Cogeneration Unit: A unit that has equipment used to produce electric energy and fonns of useful
thermal energy (such as heat or steam) for industrial, commercial, heating, or cooling purposes,
using the reject heat of one process as the energy input into a subsequent process; a unit that
uses cogeneration. These units are also known as “cogenerators.” See 40 CFR 72.2, Federal
Power Act Section 3(l8)(A), and 18 CFR 292.202.
Combined Cycle Unit: A unit that uses a heat recovery steam generator or waste heat boiler to
capture hot air exiting a steam turbine.
Combustion Device: A device that initiates the chemical reaction of fuel and oxygen with the
addition of heat.

fected are not allowed to opt-in to the Program. Note that the Opt-In Program has not been
finalized as of January 1, 1994.
Phase I Unit: Any affected unit that is subject to an acid rain emissions reduction requirement or
acid rain emissions limitation beginning in the period from January 1, 1995, to December 31,
1999. All Phase I units continue to be affected in Phase 11. See 40 CFR 72.2.
Phase II Unit: Any affected unit that is subject to an acid rain emissions reduction requirement or
acid rain emissions limitation only after January 1, 2000. See 40 CFR 72.2.

Do the Acid Rain Regulations Apply to You?
Potential Electrical Output Capacity: The MWe capacity rating for a unit. For simple combus-
lion turbines and boilers, this rating is equal to 33 percent of the maximum design input capac-
ity (in mmBtu/hr) of the steam generating unit converted to MWe. See 40 CFR 72.2.
Power Purchase Commitment: A commitment or obligation of a utility to purchase electric
power from a facility pursuant to a power sales agreement, a State regulatory authority order, a
letter of intent to purchase power from the source at a previously offered or lower price, or a
utility competitive bid solicitation that has resulted in a winning bidder. See 40 CFR 72.2.
Power Sales Agreement (PSA): A legally binding agreement between a qualifying facility, an
independent power production facility, an new independent power production facility, or a firm
associated with such facility and a regulated electric utility that establishes the terms and
conditions for the sale of power from the facility to the utility. See 40 CFR 72.2.
Qualifying Facility: A qualifying small power production facility or a qualifying cogeneration
facility as administered under the Federal Energy Regulatory Commission (FERC). See 18
CFR 292 and Federal Power Act, Sections 3(17)(C) and 3(18)(B).
Qualifying Power Purchase Commitment: A power purchase commitment in effect as of
November 15, 1990, that meets the following requirements:
U The identity of the electrical purchaser does not change, or
U The identity of the steam purchaser and the planned location of the facility do not change,
and
U The cost of compliance with the acid rain regulations are not allowed to shift to the pur-
chaser.
See 40 CFR 72.2.
Retired Unit: A unit that has ceased operation and certified that it will not recommence operation.
See 40 CFR 72.8.
Simple Combustion Turbine: A unit that is a rotary engine driven by a gas under pressure that is
created by the combustion of any fuel. This includes combined cycle units without auxiliary
firing and combined cycle units with auxiliary firing that did not use auxiliary firing in 1985
through 1987 and will not use auxiliary firing at any time after November 15, 1990. See 40
CFR 72.2.
Solid Waste Incineration Unit: A distinct operating unit of any facility that combusts any solid
waste material from commercial or industrial establishments or the general public. This does
not include most materials recovery facilities, qualifying small power production facilities, or
air curtain incinerators. See Clean Air Act, Section 129(g)(1).
Source: Any governmental, institutional, commercial, or industrial structure, installation, plant,
building, or facility that emits or has the potential to emit any regulated air pollutant under the
Clean Air Act. See 40 CFR 72.2.
Substitution Units: An affected unit that is designated as a Phase I unit in a substitution plan under
40 CFR 72.41. See 40 CFR 72.2.
Total Nameplate Capacity: The sum of the nameplate capacities to which a unit is headered.

Example 1: Listed Unit
Facts: This unit is listed in Table 2 of 40 CFR 73.10 (Exhibit 2 of Appendix D). A prospective
owner wants to buy the unit and convert it to bum only non-fossil fuels. The unit will
continue to supply steam to a 50 MWe capacity generator that sells electricity.

Example 2: Cogenerator Not Selling Electricity
Facts: This unit is not listed in Tables 1, 2, or 3 of 40 CFR 73.10 (Exhibits 1, 2, or 3 of Appen-
dix D). The cogenerator commenced commercial operation in 1988 and burns primarily
coal, but also some wood waste and natural gas. The cogenerator was constructed to
supply steam to an industrial facility. Neither the cogenerator nor the industrial facility
has sold any electricity since the commencement of operations.

Decision: The unit is unaffected, because its output does not go to the production of electricity for
sale. If the industrial facility buying the steam was using it to produce electricity that was
then sold to the public utility grid, then one would have to continue through the flow
chart to determine whether the unit is affected.

Example 3: Qualifying Facility
Facts: There are two oil- and gas-fired boilers headered to one generator at this facility. In 1986,
during the planning of the facility, the facility owners filed for self-certification of quali-
fying cogeneration facility status with the Federal Energy Regulatory Commission
(FERC). The facility is the subject of a power sales agreement, executed in 1987, for 40
MWe with a utility. The facility’s construction contract specifies a generator of 50,000
kVA at a power rating of 85% (equivalent to 42.5 MWe). The facility also has a steam
sales agreement with a local prison. The facility was completed and commenced opera-
tion in 1992 with a 43 MWe nameplate capacity generator. The power sales agreement
has not been changed or amended. The unit is not listed in Tables 1, 2, or 3 of 40 CFR 73.10

Example 4: Cogenerator Selling Electricity
Facts: An industrial company built a cogeneration facility to serve the company’s adjacent
manufacturing plant. The facility commenced commercial operation with a single boiler-
generator pair in 1991. The boiler has a maximum design heat input of 1,024 mmBtu/hr
(which calculates to potential electrical output capacity of 100 MWe), and the generator
has a nameplate capacity of 75 MWe. When the needs of the manufacturing plant are
low, the industrial company sells the excess power to a public utility. The amount of
electricity sold to the public utility (gross sales) in any one year has not exceeded, and is
not expected to exceed, 200,000 MWe-hrs. The unit is not listed in Tables 1, 2, or 3 of 40
CFR 73.10 (Exhibits 1,2, or 3 of AppendixD).

potential electrical output capacity or less than or equal to 219,000 MWe-hrs.
First, calculate the potential electrical output capacity (100 MWe), then compare this to
the generator nameplate capacity. In this example, 75% of the boiler’s capacity can be
used to generate electricity. Because this level (75%) is greater than one-third, calculate
the maximum number of MWe-hrs that could be sold at one-third potential electrical
output capacity. This figure is 292,000 MWe-brs (see Example of Cogenerator Determina-
tions on page 14 of Section 1). Since 200,000 MWe-hrs (the amount of the unit’s gross
electricity sales) is below both the 292,000 MWe-hrs and 219,000 MWe-hrs criteria, the
boiler is unaffected;

Example 5: Solid Waste Incinerator
Facts: A solid waste incinerator commenced operation in the 1970s and generally consumes 25
to 30% of its fuel in the form of number 2 diesel fuel. By 1995, the facility expects to
consume less than 20% fossil fuels by burning more consumer waste. It is not listed in
Tables 1,2, or 3 of 40 CFR 73.10 (Exhibits 1, 2, or 3 of Appendix D).

Example 6: New, Small, Clean Unit
acts: A unit is planned to commence commercial operation in March 1998. It is not listed in
Tables 1, 2, or 3 of 40 CFR 73.10 (Exhibits 1, 2, or 3 of Appendix D), nor is it listed in
the National Allowance Data Base (NADB). It is planned to consume at least 90% natu-
ral gas, so its fuels average sulfur content will be below 0.05% by weight. The boiler will
serve one generator with nameplate capacity of 15 MWe.

Appendix C
Decision: The unit is eligible for the exemption as a small, new unit burning clean fuels. It re-
ceived no allowance allocation initially, so it does not need to forfeit allowances. The unit
may be able to avoid the requirements to install and test CEMS by receiving its exemp-
tion before January 1, 1998. Without this exemption, the unit would be required to install
and certify CEMS within 90 days of the unit’s commencement of commercial operation
(see Compliance Timelines) in June 1998. if the unit files for and receives its exemption
in 1997, the exemption goes into effect January 1, 1998, in time to avoid the requirements
to install and certify CEMS (see 40 CFR 72.7(c) and 75.4(b)(1)).

Appendix C
Decision: The unit Is eligible for the retired units exemption of 40 CFR 72.8. Because it is a
Phase I affected unit, it must meet all applicable Acid Rain Program requirements until
January 1 of the year after the unit is granted its exemption. Applicable acid rain require-
ments include holding sufficient allowances to cover its annual SO 2 emissions (for emis-
sions in 1995 and thereafter), obtaining an acid rain permit, having a Designated Repre-
sentative, and installing and operating systems to monitor emissions, as required by 40
CFR75.

Example 9: Existing Unit Serving A Small
Generator
Facts: A boiler presently serves a generator with nameplate capacity of 18 MWe and, in 1985,
served only this generator. The boiler commenced operation in 1963 and sells electricity
and steam for industrial process use. Because of increased electrical demand at the
industrial site, the owner of the boiler pians to add a generator with nameplate capacity of
8 MWe in 1997.

Appendix C
Decision: The unit is currently unaffected and would remain unaffected if it adds the 8 MWe
generator. The boiler is an existing unit, and all current and planned generators served
by it have nameplate capacities of less than 25 MWe (i.e., the statutory cutoff; see Sec-
tion 402(8) of the Clean Air Act). However, if the boiler owner replaces the 18 MWe
(nameplate) generator with a generator of greater than 25 MWe nameplate capacity, the
boiler would become affected, according to 40 CFR 72.6(a)(3)(ii), which affects existing
units that serve, on or after November 15, 1990, generators with nameplate capacities
greater than 25 MWe.
