OPINION AND ORDER OF THE BOARD
(by
I.
Goodman):
This rulemaking is undertaken pursuant to Section 9.3(b)
of
the Environmental Protection Act
(the Act),
as amended by P.A.
No.
82—0540 on September
16,
1981.
P,A~No.
82-0540, known as
the “Bubble Bill” or RB 1354,was designed to enable owners and
operators of air pollution emission sources, either individually
or collectively, to utilize the most economically advantageous
mixture of control strategies to achieve environmental goals.
This usually involves overcontrolling at one emission source
and undercontrolling at another,
The statute provides that the
mixture of control strategies used
in an “alternative control
strategy”
(ACS) permit must provide equivalent protection for
the environment.
The basic concept is that an ACS should have
no negative impact on the environment and should be economically
beneficial
to
ownctr~ ~ncl
op~r.~to~.
To
i~inure that
the
unique
issues
involved
in
ACS
permits
are
adequately
addressed,
Section
9.3 authorizes the Board to promulgate standards
for issuance of
permits and a permitting program for sources utilizing alternative
control
strategies..
Section 9..3(b) authorizes the issuance of ‘~interim
regulations” within 120 days after the effective date of P.A. No.
82—0540 through an expedited rulemaking process which bypasses
Title VII requirements of the Act.
The purpose of this expedited
proceeding is to provide regulatory guidance which will enable
owners and operators to begin to plan and implement ACS
to meet
imminent compliance deadlines.
Section 9,3(c) mandates that the
Board promulgate final regulations establishing an ACS permit
program no later than December 31,
1982.
The record in this
proceeding will be consolidated with the final rulemaking to avoid
unnecessary duplication.
In addition, the final
rulemaking will
consider the economic impacts of these regulations pursuant to
Title VII of the Act.
Once effective, the final regulations will
supersede the interim rules,

The Board initiated public comment on the interim rules by
circulating a “public draft” proposal and inviting comments and
alternative
proposals..
The Illinois State Chamber of Commerce
filed
an
alternative
proposal
which
was
consolidated
for
review
with
the
Board’s
initial
proposal
under
Docket
No.
R8l-20
on
September 16,
1981.
The Illinois Environmental Protection Agency
(IEPA)
offered another alternative proposal on October
9,
1981.
These three proposals were labeled Exhibits
1,
2, and
3, respec-
tively,
in the record of the proceeding.
(Additional amendatory
language was proposed and entered into the record
in the course
of the proceeding.)
Hearings were held on R8l—20 on October 15,
16,
and
19, 1981
to consider the merits of all proposals before
the Board.
The attached proposal contains elements of each of the
proposals before the Board and also reflects the public comment
and testimony received.
Overview
Basically,
these regulations establish a permitting program.
They describe the standards for Agency issuance of
an ACS permit,
as well as the information which must be contained
in an ACS
permit application to enable the Agency to make its determination.
Due to the nature of ACS,
several aspects of the ACS
permit program differ from the standard permitting requirements
contained in Part
I of Chapter
2.
For example,
an ACS application
must provide a demonstration of “equivalence” to other existing
requirements with regard to emissions,
environmental quality,
and
methods of compliance.
In addition, each ACS emission source must
comply with unique limitations contained in its permit.
These
limitations are predicated on the compliance of all other emission
sources
in the ACS.
Thus,
specialized provisions are necessary
for recordkeeping
and reporting,
revision,
renewal, and describing
the responsibilities and liabilities of participants in multi-
person ACS.
Because ACS permits are new and potentially more complex
than other Chapter
2 permits,
the Board anticipates that extensive
communication between the permit applicant and the Agency will
occur prior to issuance of an PICS
permit.
The regulations have
been drafted to provide the flexibility necessary to tailor ACS
permits to the variety of strategies which may be proposed.
The
application information, the recordkeeping and reporting, and the
monitoring and testing provisions provide that the Agency may
request any reasonable additional information which may be needed
to make a determination and insure compliance under a particular
ACS configuration.
For example, an ACS proposals may include non-
traditional emission sources, such as fugitive emission sources,
or mobile sources.
Although these sources present special problems
and will undoubtedly require
extensive
documentation and safeguards
to insure equivalency and compliance,
it is unnecessary to address
these
special problems in the Board regulations.
The Agency can
review such applications on a case—by—case basis within the context
of these regulations..
44—278

Definitions
Chapter
2 definitions are made applicable to this Part.
(The Board notes that definitions are contained in both Parts
I
and II of Chapter 2.)
In particular, the definition of “emission
source”
(Rule 101),
i.e.,
‘any equipment or facility of a type
capable of emitting specified air contaminents to the atmosphere,”
is important in the ACS context because trades under an ACS would
focus on each “emission source” rather than an entire plant or
“source.”
It should also be noted that the definition of “person”
(Rule 101)
includes any ‘agency, political subdivision of this
State, any other state or political subdivision or agency thereof,”
Thus, governmental bodies,
as
“owners or operators,” may
participate in an ACS.
Several new definitions
are
made applicable to this Part only.
Notably,
“Actual Emissions,”
“Allowable Emissions,” “Emission
Baseline,”
“Potential to ~nit,” and “Alternative Control Strategy
(ACS)” are essential terms in an ACS context.
Some of these defi-
nitions may also be determined to apply to Part XI:
Major Source
Review Programs
in
the course of the final rulemaking on R8l-16.
If so,
a change in placement of the definitions may be appropriate
at the time that regulation is promulgated.
Definitions of “Major
Stationary Source” and “Stationary Source” were proposed to be
included in the ACS rules by Illinois EPA.
However, because ACS
focus on “emission sources,” the Board believes these definitions
are largely irrelevant to this rulemaking and that
it would be
better to focus on them in R81—16.
Standards of Issuance
Each of the four standards in Section 212.120 must be met for
issuance of an ACS
permit.
Sections 212.120(a)
and
(b)
reflect
the statutory constraints
contained in Section 39.1(a)
of the Act.
Section 212.120(c) requires that methods for determining
compliance
must be equivalent to those associated with otherwise applicable
requirements.
This requirement is necessary to insure the environ-
mental equivalence mandated by the Act.
Section 212.120(d) states
that certain regulations cannot be superseded by an alternative
strategy.
These are:
New Source Performance Standards
(Part IX),
National Emission Standards for Hazardous Air Pollutants (Part X),
and the Major Source Permit Programs (Part XI)*.
The constraint
with regard to new sources is required by Federal case law.
(See
ASARCO,
Inc.
V.
EPA, 11 ERC
1.129
(D.C. Cir. 1978).)
*The proposed Major Source Permit Program regulations are
the subject of Docket No.
R81-16.
A rule adopting the interim
Non—attainment Area portion of these rules
(Interim Rule R8l-16)
was adopted on December 17,
1981.
The final
rule
(R8l—16), which
will cover both Non-attainment and Attainment areas
is awaiting
an
Economic Impact Study.
44—279

Application Information
In addition to specific information with regard to each
emission source, the application must contain an analysis of
emissions,
environmental quality, and methods of assuring com-
pliance.
This analysis will provide the basis for the Agency
determination of compliance with the standards of
issuance and
the overall equivalence of the ACS with other regulatory and
statutory requirements.
In each analysis
(Sections 212.111,
212.112,
and 212.113) the applicant must compare the ACS with
a “base case,”
i.e., the emissions,
impacts, or methods which
would exist or be allowed under existing regulations.
Basically,
the analysis of emissions should compare ACS
emissions to the “baseline emissions,” for each source involved
in an ACS.
In addition,
to insure that emission reductions relied
on for other purposes are not “double—counted” and that other
unanticipated effects will not accompany the ACS, the analysis
must also describe emission increases from emission sources
outside the ACS which may accompany or affect the proposed ACS.
The environmental quality analysis must address air quality
impacts, risk to the public health and welfare,
and other environ-
mental impacts associated with the proposed ACS.
The scope of this
analysis is mandated by the language of PA.
82—0540 which requires
that ACS provide “e~uiva1entprotection of the environment.”
The
effect of ACS emissions on environment must be equivalent to that
of emissions which would otherwise occur or be allowed to occur.
Modeling Exemption
One component of the environmental quality analysis required
of an ACS permit applicant under these regulations is a comparison
of air quality under existing regulations and under the ACS.
Generally, dispersion modeling is required to predict the impact
of the ACS.
However, because modeling is expensive and may not
be necessary to insure air quality in some situations,
Section
212.112(a) provides that the Agency may exempt an emission source
from the general modeling requirement if one of three specified
demonstrations are made.
First, Section 212.112(a) (1) provides that if the pollutant
which is the subject of the ACS is not susceptible to modeling or
if, due to its nature, modeling will not identify its air quality
impacts, the Agency may dispense with the modeling requirement.
This,
for example, may apply to VOC or NO~ACS where modeling
is
often considered to produce ambiguous results.
Second, Section 212.112(a) (2) provides an exemption from
modeling requirements for sources located in close proximity to
one another. The rationale for this exemption
is that the accepted
modeling techniques do not distinguish the impact of an ACS trade
44—280

5
made
between
such
sources
as
long
as
plume
heights
remained
relatively the same.
(Local impacts are primarily a function
of
plume
heights,
while
long
distance
impacts
are
primarily
a
function of the distance between emission sources.)
Although
there is discussion in the record of various other distances
(R.
129—140),
the
Board
is
persuaded
by
the
logic
supporting
a
250
meter exemption.
The
250
meter
distance
represents
the
greatest
distance that could occur between the location of the actual
maximum impact and the nearest modeled receptor if a receptor
grid with 500 meter spacing is utilized.
This
is
the
grid
spacing
generally
accepted
by
USEPA
for
modeling.
Thus,
it
should
be
consistent
with
modeling
demonstrations
made
in
the
SIP
and
should
provide
equivalent
protection
of
air
quality.
It
is anticipated that sources qualifying under the 250 meter
exemption will
be considered to fall within the USEPA “Generic
Bubble” guidelines.
USEPA has indicated that it will not require
individual
SIP review of ACS permits which fall within the “Generic
Bubble”
guidelines.
(See
46
FR
20552,
April
6,
1981
(Exhibit
#10).)
Included in those guidelines
is a modeling exemption for emission
sources
located
within
a
specified
distance
from
one
another
(100
to 250 meters).
The Board has provided the 250 meter exemption as
well as the alternative exemption discussed below.
It is antici-
pated that both should meet USEPA “generic bubble” guidelines.
Section 2l2.ll2(a)(3) contains an alternative exemption from
the modeling requirement which allows a permit applicant to demon-
strate that the differences in location, plume height,
etc. are not
likely to si9nificantly affect ambient air quality.
This option
will enable applicants owning emission sources which are greater
than 250 meters apart to demonstrate that modeling is unnecessary
for their particular ACS.
A permittee may need to perform limited
modeling or monitoring to demonstrate that significance levels will
not be exceeded.
Because this exemption references the actual
concern, i.e., the impact of the ACS on air quality,
it need not
specify
distances
between emission sources.
This provision
provides needed flexibility
in light of the
fact that a question
exists within USEPA itself
as to the appropriate distance between
sources
and
the
fact
that
testimony from modelers in the record
of
this
proceeding
revealed
that
in
certain
situations
distances
between sources cannot be correlated to air quality impacts.
It
is anticipated that emission sources qualifying under this
exemption
will
fall
within
current
“Generic Bubble” guidelines
and may
be
exempt
from
individual
SIP
review.
Impacts that are to be considered “significant” are
established in Section 2l2.l12(a)(3).
These levels are taken from
the USEPA Emission Offset Interpretive Ruling, Appendix
S to 40
CFR 51.18(k).
IEPA indicated in the record that these are the
significance levels they would refer to in determining whether
modeling
is necessary
(R.
286.
Also see Exhibit #17).
To provide
an enforceable standard for all parties, these levels are included
in the Board rules.
44—281

6
USEPA drafts required that all emission points included in
the ACS be within a specified distance from one another to take
advantage of the “close proximity” exemption.
However, the justi-
fication for this position
is unclear in light of the fact that
the focus of both the required modeling and the exemption is on
the “emission sources” involved in a particular trade, rather than
the entire ACS.
(See the definition of “Emission Source,” Rule
101, Chapter 2.)
For example, under a given ACS sources A and B
may increase emissions on the condition that source C reduces
emissions to the extent necessary to offset both increases.
Since
the emission “trades” are between “A and C”
arid
“B and C,” any
change in air quality is a function of those trades.
The distance
between sources which are not
“trading” emission increases and
decreases
is irrelevant if the effect of each trade within the
ACS is adequately considered.
On a related point, Illinois
EPA’s proposal would require
dispersion modeling only for “major sources.”
Although the fact
that a source is a major source
is critical
:Ln the Major Source
Review Program context (R81—16),
it should not affect an ACS.
This is because an ACS is based on trades between individual
“emission sources” rather than entire “sources,”
as noted above.
The correct focus in these rules is on the amount of emissions
and location of the individual emission source.
Baseline
The establishment of the proper emission baseline for the
crediting of emission increases and reductions under an ACS was
hotly debated
in this proceeding.
The Board~sinitial proposal
(Exhibit
1) tracked the language of USEPA Region Vts “Generic
Bubble Rule”
and,
among other things,
related the baseline
determination to the data base relied on in the SIP.
The initial
Illinois State Chamber of Commerce proposals
(Exhibits
2 and 2(a))
proposed that existing Board emission limitations or “allowable”
emissions be used as the baseline for ACS determinations.
The
Illinois EPA (Exhibit 3) proposed that the lesser of the actual
or allowable emissions be used.
The second amended ISCC proposal
(Exhibit 2(b))
largely adopted the approach recommended by the
IEPA; however, it proposed that the definition of actual emissions
“reflect those emission levels existing prior to reductions beyond
the requirements of Board regulations which resulted from the
installation of pollution control equipment changes in process
procedures, materials or shutdowns.”
To resolve this issue,
it
is necessary to review the purposes of P.A. 82~O540and the
underlying assumptions of the air pollution control program.
The legislative intent of P.A. No.
82-0540 is stated in the
findings of the General Assembly in Section 9.3(a),
That section
indicates an intent to authorize alternative control strategies
which are “environmentally equivalent to Istrategies
required
by Board regulations or the terms of this Act” and “assure
equivalent protection of the environment.”
(Section 9.3(a)).
44—282

7
Although Section 9.3(d)
indicates that the Board may not impose
requirements which are more stringent than those required for
compliance with the Clean Air Act, the Act, or other Board
regulations, the Board must insure that ACS are environmentally
equivalent to all otherwise applicable Board regulations, not
simply the Part II emission limitations.
Rule 102 of Chapter 2 establishes the limitation that “No
person shall
cause or threaten or allow the discharge or emission
of any contaminent into the environment in any state
so as either
alone or in combination with contaminants from other sources,
.
.
to prevent the attainment or maintenance of any applicable
air quality standard.”
Thus, the emission baseline utilized in
an ACS must he established such that attainment and maintenance
of the air quality standards will not be jeopardized by emission
increases projected under the ACS.
Although this does not mean
the emission baseline used must always be “actual emissions,”
it does require, as
a minimum, that no emission reductions he
credited under an ACS which have been used as the basis for
predicting achievement of the air quality standards in Illinois.
The State Implementation Plan
(SIP)
is the “blueprint”
utilized by the State to “define the process by which air pollution
goals will be achieved.”
(Illinois SIP, Executive Summary, p.
1.)
Thus, the data used as the basis for air quality projections
in
the SIP provides the appropriate baseline for crediting increases
and decreases under an ACS.
To predict achievement and maintenance
of the air quality standards in the compliance year, the SIP relied
upon modeling which utilized the lesser of actual or allowable
emissions for emission sources.
(See SIP Volume
2,
pp.
721; SIP
Volume 3,
pp.
813;
and R.
198.)
Thus,
to assure the environmental
equivalence of ACS emissions,
it is necessary, as a general rule,
to utilize the lesser of actual or allowable emissions as the
baseline for determining creditable increases and decreases.
This conclusion is dictated by the structure of the entire
air pollution control program.
Testimony in the record also
indicated that
if owners of emission sources for which actual
emissions were utilized in the SIP demonstration were permitted
to calculate decreases in emissions from the maximum allowable
emissions limit set by Board rules, actual emissions would
increase and that, as
a result,
several areas of the state which
are currently attainment areas or unclassified areas would become
non-attainment areas
(R.
201).
As was also pointed out by
commentors, the Illinois emission limitations were promulgated as
an upper limit on the assumption that many,
in fact most,
emission
sources were emitting under the maximum allowable,
The general
use of the allowable emissions as a baseline for ACS might require
the re—evaluation and possible modification of the Board’s Part II
emission limitations.
Furthermore, it is probable that pollution would increase if
allowable emissions were used as the baseline because increments
of emission reductions take on an economic value under an ACS.
44—283

8
Under a banking system,
even emission sources which are not
involved in an ACS could “bank” credit for an artificial
emission
reduction equal to the currently unutilized emission increment or
the difference between their actual and allowable emissions.
Thus,
use of an allowable emissions baseline would create an economic
incentive for sources to utilize or “bank”
current:Ly unutilized
emission increments up to the maximum allowable emissions,
An
actual increase in pollution is inevitable under these circum-
stances.
Such an increase would be contrary to the “environmental
equivalence” intended by P.A.
No. 820540 and the basic concept
that ACS should not negatively affect the environment,
Several witnesses in this proceeding expressed concern that
businesses which are currently operating below their normal pro-
duction capacity would be penalized by use of an actual emission
baseline which reflected current conditions,
To insure that this
does not occur, the definition of actual emissions has been drafted
to require the Agency to utilize
a more representative time period
upon finding that data from the preceding two years does not
represent normal
source operation.
The burden of demonstrating
that another time period is more representative is on the permit
applicant.
On a related point,
ACS permits should retain the same degree
of flexibility as a regular permit.
The use of actual emissions
as a baseline should not be construed as a new limitation on hours
of operation or production levels.
For examp1e~an applicant may
propose that emissions be calculated as a function of units
of
production or process weight
(R.
203—205).
“Process standards”
such as these are currently used in Chapter
2, e~g.Rule 203.
The calculations made from the baseline do not create any new
prohibitions on activities which are otherwise allowable under
existing permits.
The only new requirement is that reductions
and corresponding modifications which have been committed
to
“offset” increases be maintained.
This type of commitment is not
a regulatory requirement, but rather arises as
a contractual
relationship between persons utilizing an ACS.
Notwithstanding the general baseline rule, there is an
inequity created
by disallowing emission
reduction credits for
reductions achieved by virtue of pollution controls implemented at
a time or in a situation where ACS were not available.
Although
it is impossible to resolve all
inequities, Section 212,105(b)
limits this inequity to the extent possible consistent with the
mandate of “environmental equivalence.”
Section 212.105(b)
creates an exception allowing emission reductions to he credited
under an ACS to the extent that 1) they were achieved as
a result
of actions taken to reduce emissions,
2) they reduced emissions
below required levels, and 3) they were not relied upon by the
Agency in the compliance year demonstration under the SIP.
Such
emission reductions are creditable only “to the extent” that they
meet the stated conditions.
Thus, that portion of a reduction
which is attributable to other factors or was predicted and relied
44—284

9
upon in the SIP is not creditable.
Where applicable this
authorizes a case by case determination of the appropriate emission
baseline and does not necessarily mean that the
baseline will
be
the “allowable”
level.
These three conditions, taken together, provide an equitable
approach to crediting emission reductions which were achieved as
a result of good faith actions taken to reduce emissions beyond
what is normally required.
At the same time, the condition that
an emission reduction cannot have been relied on in the SIP
demonstration insures that the crediting of these reductions will
not interfere with the State’s achievement of air quality goals.
By crediting emission reductions whenever these conditions have
been met, this provision should encourage owners of emission
sources to reduce emissions as quickly as they are technologically
capable of doing so.
The Board notes that the encouragement of
technological innovation is one of the stated purposes of P.A.
#82—0540.
This subsection may allow certain previously banked
emissions to be credited.
It also provides a potential framework
for crediting emission reductions which cannot be used in an ACS
immediately.
Although a complete “banking” system is beyond the
scope of this interim rule, this initial
framework may provide a
basis for consideration of a “banking” system in the final rule
in R81—20.
Compliance Dates
Section 212.130(a) provides that sources utilizing an
Alternative Control Strategy generally must meet the same
compliance deadlines which are otherwise required by Chapter 2.
The term “as expeditiously as practicable” is intended to indicate
that sources which can achieve compliance before the stated
deadline are required to do so.
Section 212.130(b) provides an exception to the general
rule for sources which are subject to Rule 205 of Chapter 2
(VOC
emissions).
This exception is consistent with Section 172 of the
Clean Air Act,
as
amended in 1977, which allows states to extend
the compliance date for attainment of the ozone standard until
December 31,
1987.
The record in this proceeding is replete with
testimony to the effect that many sources which would otherwise
be eligible to utilize an alternative control strategy will be
precluded from doing so in the absence of such an extension due
to the complexity of preparing and setting up an Alternative
Control Strategy before the currently applicable December 31,
1982 compliance deadline.
(See R. 29—30,
40,
49—53, 59—60,
87.)
If precluded from utilizing an ACS, many of these sources will be
forced to purchase more expensive controls to achieve the same
emission reductions.
Such a result would be contrary to the intent
of P.A.
No.
82-0540, and would result in injury to the Illinois
economy without yielding significant environmental benefits.
44—285

10
Although the extension of the compliance deadlines could be
achieved by a number of individual variance proceedings brought
before the Board pursuant to Title IX of the Act, the variance
mechanism is unworkable in this case because it would entail the
lengthy federal SIP approval process.
This approval process could
extend beyond the 1982 deadline and, thus, would prevent many
sources from utilizing an ACS.
During this approval period,
sources proposing ACS would have no assurance they could legally
implement the strategy consistent with federal
law.
Once “generic”
ACS rules are federally approved, SIP approval of individual ACS
which are of a “generic” nature is not required.
Thus,
emission
sources which
fall within the “Generic” guidelines and Section
212.130(b)
can avoid the SIP process and can begin implementing
the ACS upon issuance of the permit.
It should be noted that Section 212.130(b)
is intended to
provide a narrow exception to the general rule.
The Board has
tailored standards for the issuance of ACS permits containing
alternative compliance plans to insure that this exception
is no
broader than absolutely necessary.
To
fall within this limited
exception, the compliance plan must be contained in an Agency—
approved permit and be subject to the Agency’s public participation
procedures.
To approve such a plan,
the Agency must find that an
extension is genuinely necessary, environmentally beneficial,
and
consistent with the Clean Air Act.
In determining the necessity for extending the compliance
deadline, the Board anticipates that the Agency will consider
factors such as the complexity of the proposed ACS,
the time
required for equipment purchase and installation, and the good
faith efforts of the permittees to implement the ACS as quickly
as possible.
In addition, the Agency must find that the ACS will
result in a net benefit to the environment, either in terms
of
faster or greater emission reductions than would otherwise be
achieved.
This is justified by the fact that when compliance with
existing compliance deadlines is delayed, more pollution is added
to the environment over time than would otherwise be the case.
In
addition,
this requirement, like the “necessity” requirement, is
designed to insure that the ACS permit provisions do not become a
route
for avoiding existing compliance dates.
Finally, the require-
ment of “consistency with the Clean Air Act” requires the Agency
to
find,
among other things, that reasonable further progress
“toward attainment of the ambient air quality standard” is not
jeopardized.
“Generic Bubble” Determination
These rules, once finalized,
will be reviewed by USEPA for
compliance with the federal
“Generic Bubble” policy.
As stated
above, the “Generic Bubble” policy defines a type of relatively
simple ACS which USEPA has determined will not require individual
SIP revisions.
Although several provisions of these rules
go
44—286

11
beyond the current approved USEPA policy,
it is the function of
these rules,
as a whole, to provide a framework for all ACS, not
just simple “Generic Bubbles.”
Rather than attempting to antici-
pate USEPA,
the Board will submit the rule as
a whole and allow
USEPA to designate those portions which meet their requirements
for Generic Rules.
Proposals failing within those designated
provisions will not require individual
SIP revisions.

date equal to the mean rate at which the emission source actually
emitted the pollutant during the two-year period which immediately
precedes the particular date and which is determined by the Agency
to be representative of normal source operation;
however:
a)
The Agency shall
allow
the
use
of
a
different
time
period upon a determination that
it is more repre-
sentative of normal emission source operation.
The
burden shall be on the applicant to demonstrate that
another time period is more representative.
Actual
emissions shall be calculated using the emission
source’s actual operating hours, production rates,
and types of materials processed,
stored, or
combusted during the selected time period.
b)
If the Agency determines that there is inadequate
information to determine actual emissions as
indicated in the preceding paragraphs, the Agency
shall use the allowable emissions of the emission
source.
44—287

12
c)
For any emission source which ha~not begun normal
operations on the particular date,
actual emissions
shall equal the potential to emit of the emission
source on that day.
Allowable Emissions:
a)
The emissions rate of an emission source calculated
using the maximum rated capacity of the emission source
(unless the so~irceis subject to permit conditions or
other enforceable
limits which restrict the operating
rate,
or hours of operation,
or both)
and the most
stringent of the following:
1)
the applicable emission standard or limitation
contained in this Chapter, including those with
a future compliance date; or
2)
the emissions rate specified as a permit condition
including those with a future compliance date.
b)
The allowable emissions may be expressed as a permit
condition limiting annual emissions or material or fuel
throughout.
C)
Allowable emissions shall include a reasonable estimate
of emissions in excess of applicable standards during
start—up, malfunction, or breakdown, as appropriate.
d)
If an emission source ~s not subject to an emission
standard under provision
(a) and is not conditioned
pursuant to provIsion
,(b), the allowable emissions
shall be the potential emissions of the source.
Alternative Control Strategy
(ACS):
A specific program of
emissions limitations an4 requirements which is environmentally
equivalent to that which would otherwise be required by applicable
statutes or regulations, and under which the owner or operator of
an emission source increases emissions of a regulated pollutant
beyond the emission baseline at one or more emission sources and
correspondingly reduces emissions of the same pollutant below the
emission baseline at other emission sources.
Chapter:
References to “this chapter” or “Chapter 2” in this
Part shall
mean
Pollution Control Board air pollution rules and
regulations as contained in Chapter
2:
Air Pollution Regulations
and as codified under Title 35, Part 200, et seq., of the Illinois
Administrative Rules.
Emissions Baseline:
The starting point or reference level from
which increases an decreases in emissions are measured.
The
rules governing determination of emission offsets, calculation of
net emission increases,
and evaluation of alternative control
strategies specify the particular emission baseline that applies
for that purpose.
44—288

Multi-person ACS:
An Alternative Control Strategy which includes
emission sources which are owned and controlled by different
persons who have formed a joint venture for purposes of the ACS.
Potential to Emit:
The maximum capacity of a stationary source to
emit a pollutant under its physical and operational design.
Any
physical or operational limitation on the capacity of the source
to emit a pollutant, including air pollution control equipment and
restrictions on hours of operation or on the type or amount of
material combusted,
stored, or processed,
shall be treated as part
of its design only if the limitation or the effect it would have
on emissions is enforceable.
Secondary emissions do not count in
determining the potential to emit of a stationary
source.

Micrograms.
Section 212.102
Pursuant to a permit issued by the Agency under this Part,
a
person or persons may use an alternative control strategy (ACS)
for process or fugitive emission sources in lieu of compliance
with certain requirements otherwise applicable under this Part.
Section 212.105
Emission Baseline for Alternative Control
Strategies
a)
The baseline for reviewing decreases or increases of
emissions from emission sources proposing to utilize
an alternative control strategy shall be the lesser
of the actual emissions or the allowable emissions
prescribed by this chapter.
b)
Notwithstanding subsection
(a), an increment of
emission reduction shall be creditable under an ACS
to the extent that it:
1)
was achieved as a result of the installation
of pollution control equipment or changes in
process, procedures, or materials designed to
reduce emissions;
and
2)
reduced emissions beyond the requirements of
Board regulations; and
3)
was not relied upon by the Agency to demonstrate
or attempt to demonstrate compliance with ambient
air quality standards in the compliance year in
the State Implementation Plan demonstration.
44—289

14
C)
For purposes of subsection
(b), the burden shall
generally be on the permit applicant.
However,
for the
purpose of subsection
(b)(3) the burden
shall
be on the
Agency to demonstrate that the emission reduction in
question (from either the particular emission source or
the category of emission sources to which it belongs)
was relied upon in the SIP demonstration.
Section 212,110

Emissions
a)
A permit application under this subpart shall provide
a
comparison of the baseline emissions and the emissions
which would be permitted under the proposed ACS for each
emission source involved in the ACS.
Where appropriate,
this analysis shall address differences between the
emission sources to be
covered
by the ACS with regard
to:
1)
methods of determining emissions;
2)
consistency and reliability of the performance of
the emission sources and any associated control
devices;
44—290

15
3)
frequency and duration
of
operation
during
malfunction or breakdown,
or excess emissions
during start-up;
4)
methods of operation,
including operating schedules,
range of raw materials or products, etc.;
and
5)
other characteristics of the emission sources
or their operation which may affect equivalance
of emissions.
b)
The analysis shall describe any increases in emissions
from emission sources outside the ACS which may accompany
or affect the proposed ACS.
Section 212.112
Analysis
of Environmental Quality
a)
A permit application under this subpart shall provide
a
comparison of the ambient air quality under existing
requirements and the ambient air quality which would
exist under the proposed ACS.
This analysis shall
include dispersion modeling, unless the Agency finds
that:
1)
due to the characteristics
of the pollutant,
dispersion modeling
is inappropriate or unneces-
sary for determining effects on air quality; or
2)
the location of emission sources included in the
ACS are not more than 250 meters apart,
and the
effective plume height of the emission increases
and decreases are not significantly different, or
3)
differences
in location, plume height,
operating
practice, and other characteristics of the emission
sources subject
to the ACS are not likely to signi-
ficantly affect ambient air quality..
An effect on
ambient air quality
is significant if
it equals or
exceeds the levels specified in the following table:

the proposed ACS.
As
a minimum, the analysis shall address the
effectiveness, reliability,
and accessibility of these methods.
Section 212.120
Standards for Issuance
The Agency shall
issue a permit containing an ACS

the permit applicant demonstrates that:
a)
The ACS provides,
in the aggregate with respect to each
regulated pollutant, equivalent or less total emissions
than would otherwise be required.
b)
The impact of the ACS is environmentally equivalent to
that which would otherwise be achieved and maintained
under existing requirements.
C)
The methods for assuring compliance with the conditions
and requirements of the permit under the ACS are environ-
mentally equivalent to those that are associated with
otherwise applicable requirements.
d)
The ACS complies with any applicable requirements
contained in Parts IX, X, or XI of this chapter.

interest.
Section 212.130
Compliance Dates
a)
No owner
or operator subject to a permit utilizing an
Alternative Control Strategy is relieved of the
responsibility for achieving and maintaining a reduction
of emissions as expeditiously as practicable, but not
later than the compliance date required under other
applicable regulations.
b)
Notwithstanding subsection
(a),
an owner or operator
may demonstrate compliance with Rule 205
of this chapter
44—292

17
pursuant to an Agency—approved alternative compliance
plan contained in a permit utilizing an Alternative
Control Strategy issued prior to December
31,
1982.
The Agency
shall approve such an alternative compliance
plan upon finding
that:
1)
it extends the compliance date for each emission
source subject to the ACS no longer than necessary
to enable that emission source to utilize the ACS,
but in no case
later than December 31,
1987;
2)
the use of an alternative control
strategy will
result in either greater
or faster overall emission
reductions than would otherwise be achieved;
and
3)
such extension is consistent with the requirements
of the Federal Clean Air Act,
as amended in 1977.
Section 212.140
~2~dR~jorts
a)
