IN THE MATTER OF:

ENHANCED VEHICLE INSPECTION AND

MAINTENANCE (I/M) REGULATIONS:

AMENDMENTS TO 35 ILL. ADM. CODE 240

)

R01-12

(Rulemaking - Air)

Proposed Rule. Proposal for Public Comment.

OPINION AND ORDER OF THE BOARD (by C.A. Manning):

On August 21, 2000, the Illinois Environmental Protection Agency (Agency) filed a proposal to amend the

Board’s regulations on inspecting and maintaining vehicles to control air emissions. Today, the Board accepts the

Agency’s proposal for hearing.

BACKGROUND

Sections 182(b) and (c) of the federal Clean Air Act (CAA) (42 U.S.C §§ 7511a(b) and (c)) require states to

implement vehicle “inspection and maintenance” (I/M) programs in areas that do not meet National Ambient Air

Quality Standards (NAAQS) for ozone or carbon monoxide. Areas that do not meet NAAQS are referred to as

“nonattainment” areas.

The CAA requires “basic” I/M programs in “moderate” and “marginal” ozone nonattainment areas with

existing I/M programs. It requires “enhanced” I/M programs in “serious,” “severe,” and “extreme” ozone

nonattainment areas with a population of 200,000 or more. The CAA also requires states to submit, for the approval

of the United States Environmental Protection Agency (USEPA), revisions to their State Implementation Plans (SIPs)

that describe a satisfactory I/M program and assure that the I/M program will be implemented.

In Illinois, two areas do not meet the NAAQS for ozone: (1) the Chicago metropolitan nonattainment area,

which is a severe nonattainment area; and (2) the Metro-East St. Louis nonattainment area, which is a moderate

nonattainment area. Under Illinois’ Vehicle Emissions Inspection Law of 1995 (Vehicle Emissions Law (625 ILCS

5/13B-1

et seq.

(1998)), the Agency has proposed, and the Board has adopted, as amendments to 35 Ill. Adm. Code

240, an enhanced I/M program for these two nonattainment areas. See Enhanced Vehicle Inspection and

Maintenance (I/M) Regulations: Amendments to 35 Ill. Adm. Code 240 (July 8, 1998), R98-24; (December 1, 1994),

R94-20; (December 1, 1994), R94-19. The Agency currently proposes to further amend the enhanced I/M program.

DISCUSSION

In this portion of the opinion, the Board (1) describes the Agency’s proposal, (2) discusses the statutory

framework governing this rulemaking, (3) describes how the Board will proceed with the Agency’s proposal, and (4)

rules on the Agency’s motion to waive certain procedural requirements.

Agency Proposal

Under Section 13B-20(a) of the Vehicle Emissions Law (625 ILCS 5/13B-20(a) (1998)), the Agency proposes

amendments to 35 Ill. Adm. Code 240 with respect to the enhanced I/M program for the Chicago metropolitan and

Metro-East St. Louis nonattainment areas. See Agency Statement of Reasons at 3-4. The Agency describes its

proposed changes as follows:

delaying the implementation of “pass/fail” on-board diagnostic testing from January 1, 2001, to

January 1, 2002;

retaining current, more lenient “start-up” hydrocarbon and carbon monoxide emission standards

for model year 1981 through model year 1986 light duty vehicles, light duty trucks 1, and light

duty trucks 2; and

adding several definitions, incorporating USEPA guidance by reference, eliminating outdated

provisions, and clarifying certain provisions. See Agency Statement of Reasons at 3, 5-9, 11-13;

Agency Summary of Testimony of Elizabeth R. Tracy at 1-2.

The Agency describes these proposed changes as “relatively minor adjustments to the Enhanced I/M

program.” Agency Statement of Reasons at 5. The Agency states that it is proposing the amendments “to enable

Illinois to meet federal and state mandated enhanced emissions testing requirements.”

Id.

at 3. The Agency also

states that its proposal is “designed to promote the acceptance of and adherence to the enhanced I/M program, and

to refine certain test requirements . . . .”

Id.

at 5.

Statutory Framework

The Agency proposes to amend 35 Ill. Adm. Code 240 pursuant to Section 13B-20(a) of the Vehicle

Emissions Law (625 ILCS 5/13B-20(a) (1998)). Section 13B-20(a) provides in part:

The Agency shall propose standards necessary to achieve reductions in the emission of

hydrocarbons, carbon monoxide, and oxides of nitrogen from motor vehicles subject to inspection

under this Chapter. Within 120 days after the Agency proposes these standards, the Board shall

adopt rules establishing standards for the emission of hydrocarbons, carbon monoxide, and oxides

of nitrogen from motor vehicles subject to inspection under this Chapter. These rules may be

amended from time to time pursuant to Agency proposals.

* * *

[S]ubsection (b) of Section 27 of the Environmental Protection Act and the rulemaking provisions

of the Illinois Administrative Procedure Act shall not apply to rules adopted by the Board under

this subsection. 625 ILCS 5/13B-20(a) (1998).

How the Board Will Proceed

The Board accepts the Agency’s proposal for hearing. Because Section 13B-20(a) of the Vehicle Emissions

Law requires the Board to adopt rules within 120 days after it receives the Agency’s proposal, the Board will,

without commenting on the merits of the Agency’s proposal, proceed by publishing this proposal in the

Illinois

Register

as a proposal for public comment. The hearing officer assigned to this rulemaking will establish a deadline

for filing public comments.

Pursuant to Section 28 of the Environmental Protection Act (Act) (415 ILCS 5/28 (1998)), the Board will

hold at least two public hearings during this rulemaking. The Board will hold one hearing in Chicago and one

hearing in the Metro-East St. Louis area. The hearing officer will establish specific locations and times for the

hearings. After considering the issues raised at the public hearings and in public comments, the Board will issue a

final opinion and order and publish the adopted rules in the

Illinois Register

As set forth above, Section 13B-20(a) of the Vehicle Emissions Law states that Section 27(b) of the Act (415

ILCS 5/27(b) (1998)) and the rulemaking provisions of the Administrative Procedure Act (5 ILCS 100/1-1

seq.

(1998)) “shall not apply to rules adopted by the Board under this subsection.” 625 ILCS 5/13B-20(a) (1998).

Accordingly, the Board will not request that the Department of Commerce and Community Affairs conduct an

economic impact study of the proposed amendments pursuant to Section 27(b) of the Act. Nor will the Board submit

the proposed amendments for first or second notice pursuant to Section 5-40 of the Administrative Procedure Act (5

ILCS 100/5-40 (1998)). The Board will, however, hold public hearings and solicit public comment as described

above.

The Board directs the hearing officer to schedule public hearings pursuant to Section 28 of the Act.

Further, as noted above, the proposal will be published as a proposal for public comment in the

Illinois Register

. The

Board also notes that hearing transcripts and the Board’s opinions and orders in this rulemaking, including this

opinion and order, will be available on the Board’s Web site (www.ipcb.state.il.us).

Agency Motion

With its proposal, the Agency filed a motion to waive certain procedural requirements. Because the

proposal is several hundred pages long, the Agency asks the Board to waive certain filing and service requirements of

35 Ill. Adm. Code 102.120. See Agency Motion at 1-2. That section of the Board’s procedural rules requires the

Agency to file an original and nine copies of the proposal with the Clerk, and to serve a copy of the proposal on the

Attorney General and the Department of Natural Resources.

The Agency asks that the Board accept an original and five copies of the proposal, along with four partial

copies of the proposal. The partial copies consist of pleadings and proposed rules, but not supporting exhibits. See

Agency Motion at 2. The Agency also asks that it be allowed to serve only its Statement of Reasons and notice of the

proposal on the Attorney General, and only notice of the proposal on the Department of Natural Resources. The

Agency states that representatives of the Attorney General and the Department of Natural Resources do not object to

the motion.

Id.

The Board grants the motion.

ORDER

The Board directs the Clerk to file the following proposed amendments to 35 Ill. Adm. Code 240 with the

Secretary of State to publish in the

Illinois Register

as a proposal for public comment. Proposed additions are

underlined; proposed deletions are stricken.

(Source: Amended at Ill. Reg. , effective )

Section 240.165

Compliance Determination

Vehicle Exhaust Emission Start-Up and Final Standards - Compliance shall be determined based

upon the measurement of exhaust emissions while operating the vehicle on a dynamometer and

following the driving cycle as specified for the transient IM240 test procedures adopted by the

Agency. If the corrected, composite emission rates exceed standards for any pollutant, additional

analysis of test results shall review the second phase ("Phase 2") of the driving cycle separately.

Phase 2 shall include second 94 through second 239 of the driving cycle. Second-by-second

emission rates in grams and composite emission rates in grams per mile for Phase 2 and for the

entire composite test shall be recorded for each pollutant. For any given pollutant, if the composite

emission level is at or below the composite standard or if the Phase 2 grams per mile emission level

is at or below the applicable Phase 2 standard, then the vehicle shall pass the test for that

pollutant. Composite and Phase 2 emission rates shall be calculated in accordance with

procedures specified in "High-Tech I/M Procedures, Emissions Standards, Quality Control

Requirements, and Equipment Specifications: IM240 and Functional Evaporative System Tests,

Revised Technical Guidance," incorporated by reference at Section 240.107(c) 240.107 of this Part.

Vehicle Exhaust Emission Fast-Pass Standards - Compliance will be determined based upon the

measurement of exhaust emissions while operating the vehicle on a dynamometer and following

the driving cycle as specified for the transient IM240 test procedures adopted by the Agency.

Vehicles will be fast-passed using the following algorithm:

Beginning at second 30 of the driving cycle, cumulative second-by-second emission levels

for each second, calculated from the start of the cycle in grams, will be compared to the

cumulative fast-pass emission standards for the second under consideration. Beginning at

second 109, fast-pass decisions are based upon analysis of cumulative emissions in Phase

2, the portion of the test beginning at second 94, as well as emission levels accumulated

from the beginning of the composite test.

A vehicle will pass the transient IM240 test for a given pollutant if either of the following

conditions occurs:

cumulative emissions of the pollutant are below the full cycle fast-pass standard

for the second under consideration; or

at second 109 and later, cumulative Phase 2 emissions are below the Phase 2

fast-pass standards for the second under consideration.

Testing may be terminated when fast-pass criteria are met for all subject pollutants in the

same second.

If a fast-pass determination cannot be made for all subject pollutants before the driving

cycle ends, the pass/fail determination for each component will be based on composite or

Phase 2 emissions over the full driving cycle according to the procedures in subsection (a)

of this Section. In cases where fast-pass standards are not used, composite emission rates

in grams per mile for Phase 2 and for the entire composite test will be recorded for each

pollutant.

Composite and Phase 2 emission rates will be calculated in accordance with procedures

specified in “High-Tech I/M Procedures, Emissions Standards, Quality Control

Requirements, and Equipment Specifications: IM240 and Functional Evaporative System
