IN THE MATTER OF:

ENHANCED VEHICLE INSPECTION

AND MAINTENANCE (I/M)

REGULATIONS: AMENDMENTS

TO 35 ILL. ADM. CODE 240

)

R98-24

(Rulemaking - Air)

Proposed Rule. First Notice.

OPINION AND ORDER OF THE BOARD (by K.M. Hennessey):

On January 21, 1998, the Illinois Environmental Protection Agency (Agency) filed a

proposal to amend 35 Ill. Adm. Code 240, Enhanced Vehicle Inspection and Maintenance

Regulations. Today, the Board adopts the proposal for first notice.

Sections 182(b) and 182(c) of the federal Clean Air Act (CAA), 42 U.S.C. Sections

7582(b), 7582(c) (1990), require states to adopt “inspection and maintenance” (I/M) programs

in areas that do not meet National Ambient Air Quality Standards (NAAQS) for ozone and/or

carbon monoxide. In Illinois, two areas do not meet the NAAQS for ozone: the Metro-East

St. Louis nonattainment area, which is in moderate nonattainment with the ozone NAAQS;

and the Chicago nonattainment area, which is in severe nonattainment with the ozone NAAQS.

Agency Statement of Reasons (Agency Statement) at 2.

The CAA requires Illinois to adopt a “basic” I/M program for moderate ozone

nonattainment areas, and an “enhanced” I/M program in each urbanized area in a severe ozone

nonattainment area with a population of 200,000 or more. 42 U.S.C. Sections 7511a(b), (c)

(1996). These programs are to be included in revisions to Illinois’ State Implementation Plan

(SIP), which sets forth Illinois’ overall plan for achieving the ozone NAAQS.

Illinois has a Vehicle Emission Inspection Law (Inspection Law) currently codified at

625 ILCS 5/13B-1 - 13B-75 (1996), as amended by Pub. Act 90-475, eff. August 17, 1997.

The Inspection Law requires the Agency to propose to the Board, and the Board to adopt,

emissions standards for vehicles in portions of the Metro-East St. Louis and Chicago

metropolitan areas. The Board adopted the bulk of the standards necessary for implementation

of the enhanced I/M program as a result of the rulemakings docketed as Enhanced Vehicle

Inspection and Maintenance Regulations: Amendments to 35 Ill. Adm. Code 240 (December

1, 1994), R94-19 and R94-20. In the current proposal, the Agency proposes the remainder of

the mobile source emissions standards necessary for the implementation of the enhanced I/M

program. The proposal also clarifies and modifies existing standards.

Specifically, the Agency states that the proposed amendments modify the evaporative

system test to allow for three types of inspection of the fuel cap portion of a vehicle’s

evaporative system, rather than the current test; adds “fast-pass” standards to allow vehicles

undergoing I/M 240 exhaust emissions tests to be tested more quickly, saving time and money;

and adds standards for the required on-board diagnostic test and on-road sensing test. In

addition, the proposed rules modify requirements relating to “purge” tests, in accordance with

recent amendments to the Inspection Law. The Agency asserts that the proposal constitutes an

integral part of Illinois’ enhanced I/M SIP package and must be adopted before an enhanced

I/M SIP can be finally approved and any threat of federal sanctions under the CAA eliminated.

Agency Statement at 5.

PROCEDURAL MATTERS

Along with the proposal, the Agency filed a motion to waive certain procedural

requirements. First, the Agency asks the Board to waive the requirement that the Agency

provide an original and nine copies of the proposal and instead allow the Agency to file one

complete original, five complete copies, and four partial copies, the latter consisting of

pleadings and the proposed rules absent supporting exhibits. Second, the Agency moved that

the Board waive the requirement that it provide the Attorney General’s Office and the

Department of Natural Resources with a copy of the proposed amendments. The Agency

asserts that it has discussed the matter with both offices, who agreed that the Agency need not

supply their offices with a copy of the entire proposal. Finally, the Agency moved that the

Board waive any requirement to file with the Board a copy of the CAA, which the Agency has

relied upon but which is readily accessible to the Board. The Board grants the Agency’s

motion to waive these procedural requirements.

The Inspection Law provides that the Board is to adopt I/M rules by the identical-in-

substance rulemaking procedure under Section 7.2 of the Act, 415 ILCS 5/7.2 (1996). See

625 ILCS 5/13B-20(a) (1996). That section provides an expedited procedure for the Board to

adopt state regulations that are identical in substance to federal regulations. However, most of

the federal I/M scheme is not codified in federal regulations, but exists only as federal

guidance. In its earlier I/M rulemakings, the Board and the Agency agreed it appropriate to

proceed under Section 28.5 of the Act, 415 ILCS 5/28.5 (1996), which applies to rules that

the CAA requires the state to adopt. The Agency asserts that Section 28.5 also applies here.

The Board agrees and will proceed under Section 28.5.

Under Section 28.5 of the Act, the Board is required to proceed within set timeframes

toward the adoption of the regulation. Today the Board sends this proposal to first notice

under the Illinois Administrative Procedure Act (5 ILCS 100/5-5

et seq

. (1996)) without

commenting on the merits of the proposal. The following schedule indicates the deadlines by

which the Board must act as provided in Section 28.5 of the Act:

First Notice

on or before February 4, 1998

First Hearing

on or before March 17, 1998

Second Hearing

on or before April 16, 1998

Third Hearing

on or before April 30, 1998

Second Notice

(if 3rd hearing is canceled)

on or before May 31, 1998

(if 3rd hearing is held)

on or before June 20, 1998

Final Adoption

21 days after receipt of JCAR

certificate of no objection

The Board notes that the above dates are deadlines established by Section 28.5 of the

Act (415 ILCS 5/28.5 (1996)) and do not represent actual hearing dates or filing dates. While

the schedule includes a second and third hearing, these hearings may be canceled if no one

requests that the Board holds these hearings.

The Board notes that the Inspection Law exempts the proposed amendments from the

requirements of Section 27(b) of the Act, 415 ILCS 5/27(b) (1996). See 625 ILCS 5/13B-

20(a) (1996). Accordingly, the Board will not request that an economic impact study of the

proposal be performed.

ORDER

The Board directs the Clerk to cause publication of the proposed amendments in the

Illinois Register

for first notice:

Section 240.165 Compliance Determination

a) 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 Final Technical

Guidance" incorporated by reference at Section 240.107 of this Part.

b) Compliance Determination-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:

1) 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.

2) A vehicle will pass the transient IM240 test for a given pollutant if either

of the following conditions occurs:

A) cumulative emissions of the pollutant are below the full cycle

fast-pass standard for the second under consideration; or

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

the Phase 2 fast-pass standards for the second under

consideration.

3) Testing may be terminated when fast-pass criteria are met for all subject

pollutants in the same second.

4) 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.

5) 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

Final Technical Guidance” incorporated by reference at Section 240.107

of this Part.

SUBPART F: EVAPORATIVE TEST STANDARDS

Section 240.172 Evaporative System Pressure Test Standards

Vehicles subject to evaporative system integrity testing shall fail the evaporative system

integrity test if one of the following occurs:

Fuel Cap Pressure Decay Standards - While tested using the fuel cap pressure

decay tester, the pressure decays by 6+0.3 inches of water or more during a 10

second period after being pressurized to 28+1 inches of water column; The

vehicles shall be inspected utilizing an evaporative system pressure test adopted

by the Agency.

Fuel Cap Leak Flow Test Standards - While tested using the fuel cap leak flow

tester, the fuel cap leak flow rate exceeds 60+3 cc/min at a pressure of 30+1

inches of water column. Determination will be made by comparing the fuel

cap’s measured leak flow rate with the flow rate obtained from a calibrated

master orifice with a National Institute of Standards and Technology traceable

flow rate which will result in a pass/fail flow rate threshold of 60+3 cc/min of

air at 30+1 inches of water column; orThe vehicle shall fail the evaporative

system pressure test if one of the following occurs:

1) The system cannot maintain a system pressure above eight inches of

water for up to two minutes after being pressurized to 14 plus or minus

0.5 inches of water;

2) No pressure drop is detected when the gas cap is loosened;

3) The fuel vapor storage canister is missing or obviously damaged;

4) System vapor lines or hoses are missing or obviously disconnected; or

5) The gas cap is missing.

c) Visual Functional Test Standards - While tested using the visual functional test,

an inspection of the fuel cap reveals one or more of the following:

1) a missing fuel cap;

2) a missing or damaged o-ring, gasket, or seal;

3) missing or damaged threads, flanges, prongs, or other parts used to

secure the fuel cap to the fuel tank filler neck; and/or

4) cracks, holes, or other visible forms of tampering or damage.
