CHAPTER

2:

 AIR POLLUTION

)

Preliminary Proposal For Rulemaking.

ORDER OF THE BOARD

(by

I.

 Goodman):

During the recent legislative session

fiB

 1354 was passed

which would add §9.3 to the Illinois Environmental Protection

Act.

It

 is now awaiting the Governorts

 signature.

 That section

mandates that the Board adopt interim “bubble” rules within 120

days of the effective date of

S9.3.

 In order to meet that dead-

line the Board proposes that a “public draft” of the generic

bubble rules be published in the Environmental Register.

 This

public draft incorporates aspects of USEPA’s “Generic Bubble

Rules”,

 Indiana’s proposed bubble rules, and MB

 1354.

 The Board

intends that this draft raise issues for discussion and comment,

rather than constitute a formal proposal for rulemaking.

The

Board requests that public comment and alternative proposals on

these

 issues be submitted to the Board within the next 30 days.

These comments will he made

 a part of the record in R81-20.

The

Board orders that

 a proposed rule be noticed in the Illinois

Register and scheduled for hearings as quickly as possible

 thereafter.

IT IS SO ORDERED.

I, Christan L.

 Moffett, Clerk of the Illinois Pollution

Control~ard, hereby certify that the above Order was adopted on

~

 and other Parts of this Subtitle.

Section 212.101

 Definitions

The definitions below shall apply for the purposes of this Part.

Section 212.105 Bubble

An alternative control strategy which allows a source to reduce

control requirements at one point by increasing controls corre-

spondingly at another.

 The bubble can be applied both within

a single plant and between different plants in the same area.

 All applicable emission points are visualized as being under

one hypothetical dome with only one emission point.

Section 212.110

 Source

Any collection of emission points including fugitives within a

building, structure,

 facility, installation, article, container,

machine,

 or process equipment from which any air pollutants

emanate or are emitted, either directly or indirectly.

Section 212.115

 Emission Point

Any part of

 a source which emits or would have the potential to

emit any pollutant subject to regulation under the Clean Air Act.

Section 212.120

 Owner/Operator

Any person who owns, leases, controls, operates or supervises a

facility,

 an emission source, or air pollution control equipment.

Section 212.125

 Person

Any individual, partnership, co-partnership,

 firm, company, cor-

poration, association, joint stock company,

 trust, estate, poli-

tical subdivision or any other legal entity or their legal repre-

sentative, agency or assigns.

 Also included are the Federal,

State and local governments.

Subpart B:

 Permit Applications

Section 212.201

 Application

The owner or operator of a source,

 or different owners or

operators of two or more sources, individually or collectively

may apply for a permit pursuant to Section 39.1 of the Environ-

 mental Protection Act.

 Applications for such permits shall be

submitted on forms provided by the Agency and shall include all

information necessary to enable the Agency to make a determina-

tion pursuant to Section 39.1(a).

Section 212.02

 Alternative Control Strategy

An application for a permit pursuant to Section 39.1 of the Act

may propose a bubble which establishes alternative control

strategies for emission points including emission limitations

which are different from those which would otherwise be applic-

able under this Chapters

 The burden shall be on the applicant

to establish that this ~1ternative control strategy will not:

(a)

 increase total emission from the bubble, and

(b)

 cause or exacerbate

 a violation of applicable

ambient air quality standards.

Section 212.203

 Public Notice

Public notice of the receipt of a permit application and the

Agency’s proposed decision shall be given as required by Section

39.1(c)

 of the Act.

 In addition, public notice shall be given

of final approval of bubble applications in a newspaper of

general circulation in the county or counties where any source

to be covered by such permit is located.

Section 212,204

 Conditions Precedent to Effectiveness

No bubble shall be effective under this rule until the owner

or operator of each source included in the bubble strategy has

obtained

 a new or revised operating permit and any revised

 emissions limitations have been received by the U.S. Environ-

mental Protection Agency.

Subpart C:

 Criteria for Approval

Section 212.301

 Emission Limits

The bubble must include specific quantifiable emission limits

for each emission point in the bubble, and these limits must

43—122

—3—

be associated with

enforceable

testing

method.

These

emission

limitations

and

other

specifications

shall

incorporated

into legally binding

operating

permits

and

compliance

timetables.

Section

212.302

Type

Pollutants

Bubble

Strategies

may

 be proposed for the following pollutants:

(a)

Total

Suspendea

Particulates

(TSP)

(b)

Sulfur

Dioxide

 ISO2)

(c)

Vol~t.i1e Orgark~ Compounds

(VOC)

(d)

 Carbon MonoxidE;

 (CO)

Section

212.303

Single

 Pollutant Limitation

Each bubble must involve emissions of the same pollutant.

Section 212.304

 Even Trade Limitation

All

emissions

under

the

 bubble,

 including fugitive emissions,

must

quantifiable,

 and trades among them must be even.

 How-

ever, more than one-for—one emission trades may be required

where necessary to protect ambient air quality.

Section 212.305

 Hazardous Pollutants

No hazardous emission can be offset by a nonhazardous emission.

However, within the same criteria pollutant, hazardous emissions

may be traded for nonhazardous emission if the source decreases

the hazardous emission.

 In no case shall NESHAP’s standards be

exceeded.

Section 212.306

 Superseding Regulations

The bubble may not supersede the requirements of NESHAP’s, NSPS,

PSD or LAER regulations.

Section 212.307

 Baseline Determination

The total emissions from a bubble shall not exceed the arithmetic

sum of the baseline as determined by the following:

(a)

 For areas designated attainment under 42 USC 7407

(ci) (1)

 the baseline for each emission point will

be actual emissions determined as follows:

(1)

 If emissions from the source are separately

identified in the emission inventory used in

the State~sSIP for its ambient air quality

43—123

4—

demonstration, the baseline will be the

emissions attributed to the source in the

SIP,

(2)

 If the source is not separately identified

 in the State SIP ambient air quality demon-

strations,

 the baseline will be average

emissions calculated from the operating

history of the source for a representative

period of time

 (e,g.,~

TWO

or THREE YEARS)

up to immediately before the application is

filed.

 If historical data are deemed inade-

quate by the State, action on an application

may be delayed for up to one year while oper-

ating data are compiled by the applicant.

(b)

 For areas designated as non-attainment under 42 USC

7407 (ci) (1) which have fully approved SIPS to bring

the area into attainment the baseline for each emis-

sion point will be:

(1)

 Actual emission determined under sub-

section

 (a) (2)

 of this rule, or

(2)

 Allowable emissions established by the

SIP~

(c)

 For areas designated as nonattainment under

 42 USC

7407(d)

(1)

which do not have an approved SIP to bring

the area into attainment, the baseline will be deter-

mined as follows:

(1)

 Sources whose combined emissions

total exceed 100 tons per year

 (after

current controls) must agree to

a

USEPA approved level of control which

represents Reasonably Available Control

Technology

 (“RACT11)

 for all the emission

points

 to be included in a bubble.

(2)

 Sources whose combined emissions total are

equal to or less than 100 tons per year

(after current controls) may either:

(A)

 agree to USEPA approved RACT limits

which will be used as the baseline

for computing maximum allowable

limits from the bubble, or

43—124

—5—

(B)

 use the

baseline

established

under

subsection

(h)

 of this rule.

 If the source uses the

baseline under that subsection it must acknow-

ledge in writing that establishment of alter-

native limits does not preclude application of

more stringent RACT limits developed in the

future

212.308

 Hours of Operation and Production Rate Reduction

If limitations on hours of operations or production input rates

are used to create reductions used in the bubble, the time period

over which they are limited must be consistent with the require-

ments of this chapter,

but

in no case may the time period exceed

24 consecutive hours.

212.309

 Modeling Demonstration

When modeling is required by these rules, such modeling must show

that the alternative emission limitations will not contribute to

a new ambient air quality violation and will not interfere with

achievement of reasonable further progress toward the attainment

of national ambient air quality standards.

212.310

necessary

to determine compliance of the process line under the

bubble.

(c)

 Submit dispersion modeling of all the changes in

emissions attributable to the alternative control

strategy unless the Agency finds that either of

the following conditions are met:

(1)

 The location of all emission points included

in the bubble are not more than 100 meters

apart, and the effective plume height of the

emission increases and decreases are not

significantly different; or

(2)

 Actual emissions from each source included

in the bubble are less than 100 tons per

year.

All dispersion modeling shall be performed in

accordance with methods approved by the Agency

in conformity with the USEPA guidance outlined

in the “Guideline on Air Quality Models”, EPA

450/2—78—027

 (April, 1978.)

212.312

 Requirements Applicable to Fugitive Dust

Sources applying the bubble to control fugitive dust shall use

the best and most appropriate models, such as the Industrial

Complex Source Model, in order to show compliance with the

requirements of this Rule.

 Both annual and short—term concen-

trations must be examined, and particle deposition and fallout

should be taken into account.

 The emission factors used at

different emission points involved in trades shall be of equal

reliability.

 The modeling must use the maximum emission rates

that are legally enforceable by the Board.

 As an alternative

to modeling, sources may demonstrate the equivalency of the

trades by installing the open dust source controls and monitor

the results.

Subpart D:

 Future Emission Limitation Requirements

212.401 Effect of Future Emission Limitations

Should a new or more restrictive emission limitation become

applicable to any source included in a bubble under this Rule,

the source shall submit permit modifications demonstrating re-

ductions in total bubble emissions equal to or greater than the

reduction required by the new emission standards.

43—127

Subpart E:

 Compliance

212.501

 Other Applicable Regulations

The bubble shall not exempt any owner or operator from complying

with any other applicable regulations under this Chapter.

212.502

 Compliance Dates

No owner or operator under the bubble is relieved of the respon-

sibility for achieving and maintaining a reduction of emissions

as expeditiously as practicable, but no later than the compli-

ance date required under the applicable regulation.

212.503

 State Access to Information

The owner or operator of an emission source under a bubble shall

make available copies of reports detailing the nature, specific

emission points, and total quantities of all emissions to the

State upon verbal or written request,

 at any reasonable time.

IT IS SO ORDERED.
