STATEMENT OF REASONS 

The Illinois Environmental Protection Agency ("Illinois EPA" or '·Agency'') hereby 

submits this Statement of Reasons to the Illinois Pollution Control Board ("Board'') pursuant to 

Sections 10, 27 (excluding subsection (b)), and 28 of the Illinois Environmental Protection Act 

("Act") [ 415 ILCS 5/10, 27, and 28 (2009)], 35 Ill. Adm. Code Sections 102.200 and 102.202, 

and Section 13C-20(a) of the Vehicle Emissions Inspection Law ("VEIL") of 2005 [625 ILCS 

5/13C-20(a)) in support of the attached proposed amendments. Included in this proposal is a 

repeal of the transient loaded mode (1M240") test emission standards, developed by the United 

State Environmental Protection Agency ("USEPA") and implemented for use in the Illinois 

enhanced vehicle inspection and maintenance program ("Illinois program") for the Chicago and 

Metro-East St. Louis nonattairunent areas. This amendment proposes a repeal of the IM240 test 

emission standards due to full implementation of the onboard-diagnostic ("OBD") pass/fail 

emission inspection test and emission test standards mandated by the USEP A and required as the 

primary emission inspection test specified by the VEIL of 2005 in the Illinois program. In 

addition, this amendment proposes a repeal of all pre-1996 test standards as the VEIL of 2005 

only requires testing of 1996 and newer subject vehicles. Further, this amendment proposes a 

clean-up to definitions and incorporations by reference consistent with a repeal of the IM240 test 

emission standards, and other minor clean-up amendments. This proposal amends the most 

recent version of Part 240 as found on the Board's website. 
.,. l. STATUTORY AUTHORITY FORRULEMAKING ~ \ •t 

I 

' Section 1 O(A) of the Act provides the Board 's general authority for rulemaking 

add.ressi~g air ·pol~tion. Section 1 O(A) states in pertinent part: "The Board, pursuant to • • . • • t f • '• • l ' :· • l ~ . -

i · ·roceaures prescribed in Title VII of this Act, may adopt regulations to promote the purposes of 

this Title."' 415 JLCS 5/l O(A) (2009). Further, Section 27(a) of the Act confers general 

substantive rulemaking authority upon the Board and the contents of this regulatory proposal are 

dearly within these general rulemaking powers of the B.oard. This proposal is being filed as a 

regulatory proposal of general applicability pursuant to Sections 27 (excluding subsection (b)) 

and 28 of the Act. 415 ILCS 5/27 and 28 (2009). It is not being proposed as an identical-insubstance, fast-track or federally required rulemaking. In evaluating this proposal, the Board is 

required to take into account "the existing physical conditions, the character ofthe area involved, 

including the character of surrounding land uses, zoning dassifications, the nature of the existing 

air quality, or receiving body of water, as the case may be, and the technical feasibility and 

economic reasonableness of measuring or reducing the particular type of pollution.'' 415 ILCS 

5/27(a) (2009). In addition, this proposal is being filed under the authority of Section 13C-20(a) 

of the VEIL of 2005. 625 ILCS 5113C-20(a) (2009). Section 20(a) of the VEIL of 2005 states, 

in relevant part, that the Board is required to adopt standards necessary for the enhanced 

inspection and maintenance program within 120 days after the Agency proposes those standards 

to the Board, and that: 

" ... subsection (b) of Section 27 of the Environmental Protection Act and the rulema.king 

provisions of the Illinois Administrative Procedure Act do not apply to rules adopted by 

the Board under this subsection." 

625 ILCS 5/l3C-20(a) (2009). 

The Agency believes that the proposed rules contained herein constitute those rules 

2 
referenced by the above statutory requirement, and that the Board will insure adoption of such 

rules within the required timeframe. 

II. STATEMENT OF FACTS 

Section 182 of the Clean Air Act ("CAA") requires the implementation of vehicle 

inspection and maintenance ("I!M") programs in areas not meeting the National Ambient Air 

Quality Standards ("NAAQS") for ozone. 42 U.S.C. § 7511a (2009). By way of background, 

the 1977 CAA Amendments required vehicle liM programs in areas with long standing air 

quality problems. 57 Fed. Reg. 52950 (Nov. 5, 1992). The 1990 CAA Amendments expanded 

the role of VM programs as an attainment strategy. Jd. These amendments mandated the use of 

"basic" or "enhanced" liM programs and required USEPA to develop different performance 

standards for these two programs. !d. The performance standard is the minimum amount of 

emission reductions that a program is required to achieve based on USEPA's model program. 

Jd. Thus, in achieving the performance standard, a state must use USEPA's mobile source 

emission factor model available at the time of state implementation plan ("SIP") submittal to 

demonstrate that its program will achieve emission levels that are equal to or lower than those 

achieved by USEPA's model program. !d. Also, the 1990 Amendments required USEPA to 

address requirements for design elements and program implementation issues for both programs. 

!d. Basic I/M programs are required in "marginal" ozone nonattainment areas with existing liM 

programs and in "moderate" ozone nonattainment areas. 42 U.S.C. § 7511 a (2009). Enhanced 

IIM programs are required in "serious," "severe," and "extreme" ozone nonattainment areas with 

urbanized populations of 200,000 or more. Jd. In Illinois, there are two areas classified 

nonattainment for ozone: the Chicago metropolitan area which was classified as "severe" under 

the revoked 1-hour ozone standard and now classified as "moderate" under the current 8-hour 

3 
standard; and the Metro-East St. Louis area which was redesignated to attainment of the !-hour 

standard and is now classified as "moderate" nonattainment for ozone under the current 8-hour 

standard. 40 C.F.R. § 81.314 (2009). While enhanced liM was required in the Chicago area and 

not required in the Metro-East St. Louis area, Illinois chose to implement enhanced 1/M in the 

Metro-East St. Louis area as part of its strategy to meet attainment of the ozone standard. Today, 

Illinois continues to implement enhanced 1/M in both the Chica'go and Metro-East St. Louis areas 

as part of its strategy to meet attainment of the ozone standard. 

USEP A has promulgated final regulations containing emissions testing standards and 

procedures for use in enhanced 11M testing programs, which it has amended over the years [40 

CPR Part 51, SubpartS and 40 CFR Part 85, Subpart W]. In response to federal requirements, 

·Illinois enacted the VEIL, amended over the years, which mandates and sets forth requirements 

for enhanced vehicle UM testing and provides authority for the Agency to meet USEPA's 

enhanced VM testing and performance criteria. See 625 ILCS 5/13C (2009). In addition, the 

Board adopted the test standards necessary for implementation of enhanced 1/M in 35 Ill. Adm. 

Code Part 240 [R94-20 at 18 Ill. Reg. 18013 (eff. Dec. 12, 1994), R94-19 at 18 Ill. Reg. 18228 

(eff. Dec. 20, 1994), R98-24 at 22 Ill. Reg. 13723 (eff. Jul. 13, 1998, expedited correction at22 

IlL Reg. 21120, eff. Jul. 13, 1998), R01-12 at24 Ill. Reg. 19188 (eff. Dec. 18, 2000), and R02-8 

at 25 Ill. Reg. 16379 (eff. Dec. 18, 2001)]. Further, the Agency has adopted procedural rules 

relating to implementation of the lllinois program at 35 Ill. Adm. Code Part 276, and is currently 

updating such rules. 

This ru.lemaking proposes to repeal the IM240 test em1sswn standards, including 

definitions, incorporations, and related language consistent therewith; proposes to repeal all pre1996 test emission standards based on the VEIL of 2005; and proposes other minor clean-up 

4 
amendments. 

III. PURPOSE AND EFFECT OF THE PROPOSAL 

As stated supra, Section 182 of the CAA requires implementation of 1/M programs in 

areas not meeting the NAAQS for ozone. Also as stated supra, the Chicago metropolitan and 

Metro-East St. Louis areas are cuiTentJy designated nonattainment for ozone under the 8-hour 

standard. Federal regulations require the adoption by states of standards that result in a reduction 

of vehicle emissions through testing procedures meeting, or exceeding, the amount of emissions 

that would be reduced if its "model" liM program design was implemented. 57 Fed. Reg. 52950. 

USEP A requires certain design elements to be a part of any enhanced liM program, but allows 

states to vary certain elements and program inputs as long as the plan achieves the same or 

greater reductions in emissions than those required . by USEP A's applicable performance 

standard. Jd. The enhanced performance standard requires the following program elements: (1) 

network type~ (2) required start date~ (3) annual test frequency; ( 4) model year coverage; (5) 

vehicle type coverage; (6) exhaust emission test type; (7) emission standards; (8) emission 

control device inspections; (9) evaporative system function checks; (10) stringency or failure 

rate; (11) waiver rate; (12) compliance rate; and (13) evaluation date. 40 C.F.R. § 51.351 (2009). 

As stated supra, the Board has adopted required test emission standards for the enhanced lllinois 

program in 35 Ill. Adm. Code 240 and the Agency has adopted certain procedural rules 

incorporating required program elements to implement the Illinois program in 35 Ill. Adm. Code 

276. Such rules have been submitted to USEPA, Region V, and approved as revisions to th:e 

Illinois SIP. See 61 Fed. Reg. 38582 (July 25, 1996) and 64 Fed. Reg. 8517 (Feb. 22, 1999). 

The Illinois EPA will be submitting these rules, as adopted, to USEPA, Region V, for approval 

and inclusion into the Illinois SIP as well. 

5 
Based on the CAA Amendments of 1990, in 1992, USEP A promulgated I/M regulations; 

however, it reserved sections for OBD liM testing which it was still developing. 57 Fed. Reg. 

52950. Consequently, in 1992, there was no requirement for OBD testing of subject vehicles. In 

1996, USEP A amended the 1992 I/M rule and established OBD liM requirements for I/M 

performance standards. 61 Fed. Reg. 40940 (Aug. 6, 1996). This 1996 amendment established 

the mandatory requirement for OBD testing of 1996 and newer vehicles. !d. However, this 

amendment did not require implementation of OBD testing until 1998 or 1999 depending on the 

area, and a vehicle required to have an OBD test would not fail the overall vehicle inspection and 

maintenance test if it failed the OBD test until January 1, 2000. ld. Therefore, full 

implementation of OBD pass/fail was extended out into future years. 

In 1998, USEP A amended the liM rule to delay the date by which liM programs had to 

implement OBD testing to no later than January 1, 2001, due to pending studies of the 

effectiveness of OBD testing. 63 Fed. Reg. 24429 (May 4, 1998). In 2001, USEPA amended 

the liM rule to update and streamline OBD IIM requirements for effective implementation of 

OBD I/M testing. 66 Fed. Reg. 18156 (April 5, 2001 ). In this amendment, USEP A, among 

other things, provided states with several options for extending the current deadline for 

implementation of mandatory OBD testing, ultimately allowing until January 1, 2003, for 

implementation, plus an optional phase-in of OBD testing for one test cycle. /d. 

OBD IIM pass/fail testing is now required for all subject vehicles of model year 1996 and 

newer. See 40 C:'F.R. § 51.35l(c) (2009) and 40 C.F.R. § 51.357(b)(4) (2009). In addition, 

federal regulations allow states to utiEze the OBD 11M test and test standards in lieu of the 

obsolete and non-beneficial IM240 and other exhaust and evaporative tests. See 40 C.F.R. § 

51.357(a)(l2) (2009) and 66 Fed. Reg. 18156. Further, federal regulations allow states to vary 

6 
vehicle model year coverage from USEPA 's model program assumptions regarding vehicle 

model year coverage provided necessary emission reductions are achieved. 40 C.F.R. § 51.356 

(2009). 

The VEIL was originally adopted by the Illinois legislature in 198~ and provided 

authority for an liM program. 625 ILCS 5/13A (1984). In 199( the Illinois legislature adopted 

the VEIL of 1995 which provided authority for the Agency to implement enhanced 1/M. 625 

ILCS 5/138 (1995). In addition, the VEIL of 1995 provided for testing of model year 1968 and 

newer subject vehicles, centralized testing (test-only, no repair), and required inspections to 

consist of a loaded mode exhaust gas analysis, evaporative system integrity test, OBD system 

check, and verification that all required emission-related recall repairs were made, among other 

requirements. !d. The elements of. the VEIL of J 995 were based on USEPA's model IIM 

program, with some approved variation. 

In 2005, the Illinois legislature adopted the VEIL of 2005, which, among other things, 

added definitions relating to OBD testing, added the OBD test as the primary JIM test and 

maintained the steady-state idle exhaust and evaporative system integrity test as secondary tests, 

removed the transient loaded mode test, exempted vehicles of model year 1995 and older from 

VM testing, and allowed for a hybrid program (emissions testing and repair). The VEIL of2005 

was based on amendments to federal rules (mandatory OBD pass/fail testing) and programmatic 

improvements and modifications necessary in the enhanced Illinois program, while, at the same 

time, continuing to assist in bringing Illinois 8-hour ozone nonattainment areas into attainment. 

The purpose of this proposal is to repeal the IM240 test emission standards, including 

corresponding definitions and references. The effect of repealing the IM240 test emission 

standards is to essentially reflect full applicability of federal OBD pass/fail testing in accordance 

7 
with, and as required by, federal law and the VEIL of 2005. All other test standards (OBD, 

steady-state idle exhaust, evaporative system integrity, and on-road remote sensing) remain in 

the rule. Concunently with this proposal, the Agency will be proposing amendments to the 

Agency's JIM procedural rules located at 35 Ill. Adm. Code Part 276 to reflect full applicability 

of the federal OBD pass/fail test as the primary inspection and maintenance test; to reflect other 

changes consistent with the VEIL of 2005; and also to make other programmatic changes. 

Another purpose of this rulemak.ing is to repeal all pre-1996 test emission standards as a 

result of the exemption of 1995 and older vehicles from emissions testing in accordance with the 

VEIL of 2005. This includes pre-1996 test emission standards for the steady-state idle exhaust, 

evaporative system integrity, and on-road remote sensing tests. Finally, this rulemaking 

proposes minor clean-up amendments which consist of updates and corrections to the rule. 

IV. GEOGRAPHlC REGIONS AND SOURCES AFFECTED 

The geographic regions that are subject to this proposal include those "affected counties" 

as defined in Section 13C-5 of the VEIL of 2005. 625 ILCS 5/13C-5 (2009). Specifically 

included are the following counties in the Chicago and Metro-East St. Louis areas: Cook, 

DuPage and Lake, and portions of Kane, Kendall, McHenry, Will, Madison, Monroe and St. 

Clair counties. The sources affected by this proposal include motor vehicles subject to the 

provisions of the VEIL of 2005 and the owners of such vehicles. The Illinois EPA has not 

included a list of affected sources with this proposal due to the burden of compiling such a 

·substantial list of sources. However, for the year 2008/2009 test cycle, there were approximately 

3.2 million initial tests conducted in the State. For the 2012/2013 test cycle, the Illinois EPA 

estimates that there will be 3.6 million initial tests conducted in the State. The affected sources 

will not be negatively impacted by this proposal because it reduces the population of affected 

8 
vehicles and does not impose any additional requirements. 

V. TECHNICAL FEASIBILITY AND ECONOMIC REASONABLENESS 

Section 27 of the Act requires the Board to consider the technical feasibility and 

economic reasonableness of all rulemaking proposals. In this rulemaking, the Illinois EPA is not 

proposing any new technology or requirements. The federal OBD test standards, which replace 

the IM240 test emission standards as the primary inspection test standards, have already been 

incorporated into Part 240. Further, the OBD pass/fail test is required by federal regulations, the 

VEIL of 2005, and the Illinois EPA's procedural rules at 35 Ill. Adm. Code Part 276. As stated 

supra, federal regulations allow the OBD test to replace other emissions tests, such as the IM240 

test. In addition, the removal of the IM240 test procedures (concurrently proposed in 

amendments to 35 IlL Adrn. Code Part 276) and IM240 test standards dramatically reduce the 

cost of the Illinois program and are not economically reasonable to retain. In addition, 1995 

model year and older vehicles are exempt from the emissions inspection requirement as specified 

by the VEIL of 2005 and allowed by federal regulations. This exemption was established 

because these vehicles are becoming outdated and being replaced by newer and more efficient 

vehicles. The Illinois EPA's analysis, explained in detail in sections entitled "Elimination of 

Transient Loaded Mode Exhaust Test (IM240)" and "Exemption of Pre-1996 Model Year 

Vehicles" of the Technical Support Document, further demonstrates the technical feasibility and 

economic reasonableness of the Illinois EPA's proposal. 

VI. COMMUNICATION WITH INTERESTED PARTIES 

As required by the CAA, the Board conducted rulemak.ing proceedings relating to 

adoption of I/M test standards throughout the 1990s and early 2000s. Those required 

rulemak.ings were approved and adopted by the Board, including the IM240 test emission 

9 
standards and the OBD test emission standards. In addition, at various times during the 1990s. 

the Agency adopted procedural rules necessary for implementing the enhanced 1/M program, and 

will simultaneously amend such rules to be consistent with this rulemaking and also for the 

purpose of updating other aspects of the enhanced 1/M program. Further, as the bulk of this 

proposal (repeal of the IM240 test emission standards and exemption of pre-1996 vehicles) is 

effectuating amendments to the VEIL of 2005, significant public outreach was conducted 

through the legislative process. Additional amendments simply involve minor updates, 

clarifications and corrections. 

VII. ILLINOIS EPA'S PROPOSAL 

The following is a section-by-section summary of the illinois EPA's proposal. 

SUBPART A: Definitions and General Provisions 

Section 240.102: Definitions 

This Section sets forth the definitions used in this Part. The Illinois EPA proposes to 

clarify that terms defined in the VEIL of 2005, and used in this Part, apply to this Part. Also, the 

Tilinois EPA proposes to repeal the following definitions: "adjusted loaded vehicle weight;" 

"IM240;" "loaded mode;" "loaded vehicle weight;" and "transient loaded mode test" because 

these definitions all relate to the IM240 test emission standards proposed to be repealed with this 

rulemaking. In addition, the Illinois EPA proposes to repeal the definition of "full power 

position" because it is no longer referenced in the Part. Further, the Illinois EPA proposes to 

revise the definitions of "steady-state idle test" and "preconditioning mode" to reflect the 

removal of the loaded pre-conditioning mode requirement in the steady-state idle exhaust test. 

Section 240.104: Inspection 

This Section sets forth references to various emission standards which subject vehicles 

10 
must comply with when tested. The Illinois EPA proposes to remove references to Sections 

240.162 and 240 .163 relating to IM240 test emission standards as such standards are proposed to 

be repealed with this rulemaking and also to update the reference of the VEIL to its current 

versiOn. 

Section 240.105: Penalties 

This Section sets forth the penalties associated with noncompliance. The Illinois EPA 

proposes to remove references to Sections 240.162 and 240.163 relating to IM240 test emission 

standards as such standards are proposed to be repealed with this rulemaking and also to make 

other minor grammatical revisions. 

Section 240.106: Determination of Violation 

This Section sets forth methods for determining violations of various standards contained 

in this Part. The Illinois EPA proposes to remove reference to Sections 240 .162 and 240.163 

relating to the IM240 test emission standards as such standards are proposed to be repealed with 

this rulemaking and also other minor grammatical revisions. 

Section 240.107: Incorporations by Reference 

This Section sets forth the documents that are incorporated by reference with this Part. 

The Illinois EPA proposes to remove the IM240 technical guidance document in subsection (b) 

of this Section as such guidance will no longer be applicable with the repeal of the IM240 test 

emission standards. 

SUBPART D: Steady-State Idle Mode Test Emission Standards 

Sec6on 240.151: Applicability 

This Section sets forth applicability of the steady-state idle exhaust emission standards. 

The Illinois EPA proposes to clarify the applicability of this Section and update the reference of 

1 I 
the VEIL to its current version. 

Section 240.152: Steadv-State Idle Mode Vehicle Exhaust Emission Standards 

This Section sets forth steady-state idle exhaust emission standards for subject vehicles. 

The Illinois EPA proposes to repeal pre-1996 steady-state idle exhaust emission standards 

because 1996 and newer vehicles are the only vehicles subject to the emissions inspection 

requirement of the VEIL of2005. 

Section 240.153: Compliance Determination 

This Section sets forth the method for determining compliance with the steady-state idle 

exhaust emission standards. The Ulinois EPA proposes to remove reference to the loaded 

preconditioning mode because it is no longer utilized. 

SUBPART E: Transient Loaded Mode Test Emission Standards 

Section 240.161: Applicability 

This Section sets forth applicability of the IM240 test emission standards. The Illinois 

EPA proposes to repeal this Section because the IM240 test is not allowed by statute; therefore, 

the IM240 emission standards must be repealed. 

Section 240.162: Vehicle Exhaust Emission Start-Up Standards 

This Section sets forth effective dates for vehicles subject to the IM240 vehicle exhaust 

emission start-up standards. These standards are applicable to vehicles by cross-referencing 

those standards contained in Table A to this Part. The Illinois EPA proposes to repeal this 

Section because the IM240 test is not allowed by statute; therefore, the IM240 test emission 

standards must be repealed. 

Section 240.163: Vehicle Exhaust Emission Final Standards 

This Section sets forth effective dates for vehicles subject to IM240 vehicle exhaust 

12 
emission final standards. These standards are applicable to vehicles by cross-referencing those 

standards contained in Table B to this Part. The Illinois EPA proposes to repeal this Section 

because the IM240 test is not allowed by statute; therefore, the IM240 test emission standards 

must be repealed. 

Section 240.164: Vehicle Exhaust Emission Fast-Pass Standards 

This Section sets forth the applicability of IM240 vehicle exhaust emission fast-pass 

standards to subject vehicles. These standards are applicable to vehicles by cross-referencing 

those standards contained in Table C to this Part. The Illinois EPA proposes to repeal this 

Section because the IM240 test is not allowed by statute; therefore, the IM240 test emission 

standards must be repealed. 

Section 240.165: Compliance Determination 

This Section sets forth methods for determining compliance with IM240 test et:nission 

standards. The Illinois EPA proposes to repeal this Section because the IM240 test is not 

allowed by statute; therefore, the methods for determining compliance must be repealed. 

SUBPART F: Evaporative Test Standards 

Section 240.171: Applicability 

This Section sets forth the model year applicability for vehicles subject to the evaporative 

test standards. The Illinois EPA proposes to clarify the applicability of this Section. 

SUBPART G: On-Road Remote Sensing Test Emission Standards 

Section 240.181: Applicabilitv 

This Section sets forth the applicability of on-road remote sensing test emission standards 

to subject vehicles. The Illinois EPA proposes an update to this Section to clarify the 

applicability of this Section and to reflect the Illinois EPA's past promulgation of on-road remote 

13 
sensing exhaust emission test procedures. 

Section 240.182 On-Road Remote Sensing Emission Standards 

This Section sets forth the on-road remote sensing emission standards for subject 

vehicles. The Illinois EPA proposes to repeal pre-1996 on-road remote sensing emission 

standards because 1 996 and newer vehicles are the only vehicles subject to the emission 

inspection requirement of the VEIL of2005. 

SUBPART H: On-Board Diagnostic Test Standards 

Section 240.191 Applicability 

This Section sets forth the applicability of the OBD test emission standards. The Illinois 

EPA proposes to clarify the applicability of this Section. In addition, the Illinois EPA proposes 

to repeal the last sentence of this Section to reflect full implementation of "pass/fail" OBD 

testing. 

Section 240.Table A Vehicle Exhaust Emission Start-Up Standards 

This Section sets forth a table of IM240 vehicle exhaust emission start-up standards. The 

Illinois EPA proposes to repeal this Section because the IM240 test is not allowed by statute; 

therefore, the IM240 emission standards must be repealed. 

Section 240.Table B Vehicle Exhaust Emission Final Standards 

This Section sets forth a table of IM240 vehicle exhaust emission final standards. The 

Illinois EPA proposes to repeal this Section because the IM240 test is not allowed by statute; 

therefore, the [M240 test emission standards must be repealed. 

Section 240.Table C Vehicle Exhaust Emission Fast-Pass Standards 

This Section sets forth a table of IM240 vehicle exhaust emission fast-pass standards. 

The Illinois EPA proposes to repeal this Section because the IM240 test is not allowed by statute; 

14 
therefore, the IM240 test emission standards must be repealed. 

VIII. CONCLUSION 

For the reasons stated above, the Illinois EPA hereby submits this regulatory proposal 

and respectfully requests the Board to adopt these amendments for the State of Illinois.

5) A Complete Description of the Subjects and Issues Involved: The illinois Environmental 

Protection Agency's (Illinois EPA) proposal would amend Part .240 to reflect the 

adoption of the Vehicle Emissions Inspection Law of 2005 (VEIL of 2005) (625 ILCS 

5/13C) and to make clarifications and minor cleanups to the rule. The VEIL of2005 was 

a replacement for, and continuation of, the program established under the Vehicle 

Emissions Inspection Law of I 995 (VEIL of 1995) (625 ILCS 5/138). The VEIL of 

2005 was modeled off of the VEIL of 1995, but exempted model year 1995 and older 

vehicles from inspection, replaced the transient loaded mode (IM240) emissions 

inspection test with the OBD inspection test as the primary vehicle inspection test, 
ILLINOIS REGISTER 

POLLUTION CONTROL BOARD 

NOTICE OF PROPOSED AMENDMENTS 

maintained the steady-state idle exhaust gas analysis and evaporative system integrity 

emissions tests as secondary emissions tests, and made other additions. 

The proposed amendments to Part 240 have been developed to reflect the VEIL of2005. 

The proposed amendments remove definitions relating to the proposed removal of the 

IM240 emissions standards, remove definitions no longer referenced, and revised other 

definitions. The amendments propose the repeal of Subpart E, all Tables, an 

incorporation by reference, and all other references to the IM240 emissions standards to 

reflect full implementation of the OBD inspection test and standards. The amendments 

propose the repeal of all pre-1996 emissions standards to reflect the exemption of pre1 996 vehicles from the emissions inspection requirement, as provided by the VEIL of 

2005. The proposed amendments reflect the full implementation of the OBD test and 

standards, clarify the applicability of various sections by tying applicability to the 

specific provisions of the VEIL of 2005, and make other minor updates and corrections. 

The lllinois Pollution Control Board (Board) is required by the VEIL of 2005 to adopt 

this proposal within 120 days after submittal by the Illinois EPA [ 625 ILCS 5/13 C-20].

vehicle emissions test standards contained in 35 Ill. Adm. Code Part 240. These revisions 

are the result of modifications to the Illinois Vehicle Code signed into law on August I 0, 

2005. Specifically, the Vehicle Emissions Inspection Law of2005 ("VEIL of2005") (625 

ILCS 5/13C) replaced the Vehicle Emission Inspection Law of 1995 ("VEIL of 1995") 

(625 ILCS 5113B) ofthe Illinois Vehicle Code, beginning February 1. 2007. The plimary 

modifications-of the law include the following: 

a) Required full implementation of OBD pass/fail testing as the primary method of 

compJiance determination; 

b) Eliminated transient loaded mode exhaust testing (also known as IM240) after 

January 31, 2007; 

c) Required steady-state idle exhaust and fuel cap evaporative system integrity 

testing on non-OBD compliant vehicles; 

d) Exempted pre-1996 model year vehicles in compliance with the emissions test 

requirement as ofFebruary 1, 2007~ and, 

e) Eliminated the fuel cap test for OBD compliant vehicles. 

These proposed revisions to the emissions test standards reflect applicable statutory 

changes listed above_ 

DEFINITIONS 

AIJ definitions and language associated with the transient loaded mode exhaust test were 

removed or revised due to the dropping of this test procedure. These are: 

a) 11Adjusted loaded vehicle weight (AL VW) 11 

b) "IM240" 

c) "Loaded mode'' 

d) "Loaded vehicle weight (L VW)" 

e) "Transient loaded mode test" 

The definitions of "Steady-state idle test" and "Preconditioning mode" were revised to 

reflect the removal of the loaded pre-conditioning mode requirement in the steady-state 

idle exhaust test. 

In addition, the definition of "Full power position" was deleted because it is not 

referenced; and therefore, is a clean-up. 

2 
ELIMINATION OF TRANSIENT LOADED MODE EXHAUST TEST (IM240) 

The elimination of the IM240 test was based upon federal guidance suggesting its 

removal and modeling projections showing negligible emission reduction benefits and 

significant long-term costs for continued use of this test. According to federal law, all 

1996 and newer model year vehicles equipped with OBD technology are subject to the 

OBD test. Initially with this requirement came various compliance alternatives including 

delayed full implementation of OBD pass/fail testing. Consequently, the VEIL of 1995 

(625 1LCS 5113B-25(d)(2)) was amended to prevent the 1M240 test from being 

performed on vehicles that were equipped with the OBD system. With full 

implementation of OBD pass/fail under the VEIL of2005 (625 ILCS 5/13C-25(c)), a 

vehicle failing the OBD test was no longer allowed a fallback exhaust test. Ths greatly 

reduced the number ofiM240 tests conducted in the program. 

Based on the federal OBD pass/fail requirements, the State Legislature adopted the VEIL 

of 2005 which was designed to achieve the following goals: 

a) Dramatically reduce the cost ofthe program; 

b) Maintain/improve motorist acceptance of testing; and, 

c) Focus testing on vehicles expected to be in the Illinois fleet during the 2007-2013 

timeframe. 

Based on modeling projections of the expected Illinois fleet for 2012, approximately 90% 

of the volatile organic compound (VOC) reductions would come from OBD equipped 

vehicles. 1 Given the fact that the IM240 test was only used on pre-1996, non-OBD 

equipped vehicles, a small portion of the vehicles subject to testing in the future, and that 

the cost was significantly higher than OBD testing, the Legislature eliminated the 

requirement for any transient loaded mode testing in Illinois' program. 

The main effect ofthis change is the elimination of all references to the transient loaded 

mode test standards in 35 Ill. Adm. Code 240, Subpart E, and all tables. 

EXEMPTION OF PRE-1996 MODEL YEAR VEHICLES 

The exemption of pre-1996 model year vehicles was based upon modeling projections 

showing negligible emission reduction benefits and significant long-term costs for 

continued testing of these vehicles. 

As stated earlier in this document, one qfthe main goals in the drafting of the VEIL of 

2005 was to design a test program around the fleet of vehicles that will exist in 2007 

through 2013. Based on the current subject vehicle fleet in Illinois and projections 

through 2013, the percentage of vehicles that are 1995 model year or older will fall from 

27% in 2007 to 5% in 2013.2 The Agency could find no justification for maintaining a 

test procedure that would only be used on 5% of the vehicle fleet in the out-years of the 

test program, especially given the cost of maintaining this test procedure. 
Based on MOBIL£6.2 modeling, exempting pre-1996 model year vehicles and dropping 

the IM240 test in the Illinois [/M program would result in the loss ofVOC emissions 

reductions of approximately 4.8 tons per day for the Chicago non-attairunent area and 0.8 

tons per day for the Metro-East non-attainment area in 2009. However, by 2013, this loss 

will fall to 1.0 ton per day in Chicago and 0.3 tons per day in Metro East as the 

percentage of OBD-equipped vehicles increases in each respective fleet. 3

.4 This small 

loss in emissions reductions has been accounted for in the 8-hour ozone and PM2.5 

attainment demonstrations, as well as the respective mobile source emissions budgets 

used in conducting transportation confonnity. 

Therefore, the decision was made to exempt all pre-1996 model year vehicles and 

eliminate the applicable test procedure (IM240). As stated in the previous section, the 

main effect of this change in exempt vehicles is the elimination of all references to the 

IM240 test standards in 3 5 IlL Adm. Code 240, Subpart E, and all tables. 

However, the steady-state idle and evaporative test procedures are still applicable for 

1996 and newer vehicles that cannot receive an OBD test Also, the on-road remote 

sensing test is still applicable to 1996 and newer vehicles. Therefore, the current steadystate idle, evaporative, and on-road remote sensing test standards contained in 35 Ill. 

Adm. Code 240, Subparts D, F and G have been modified to apply only to 1996 and 

newer vehicles. 

FULL IMPLEMENTATION OF OBD PASS/FAIL TESTING 

Full implementation ofOBD pass/fail testing did not have any impact on the OBD test 

standards specified in 35 Ill. Adm. Code 240, Subpart H. The only revision in this 

Subpart was to update the OBD test applicability requirements to match those specified 

in the current statute (Illinois Vehicle Code (625 ILCS 5/13C-25)). 

ADDITIONAL GENERAL REVISIONS 

The following general revisions were made for the reasons specified: 

a) Section 240.104 Inspection 

This section was revised to reference the proper VEIL and to remove the 

references to the repealed IM240 test standards. 

b) Section 240.105 Penalties 

This section was revised to reference the proper VEIL, to remove the references 

to the repealed IM240 test standards, and to correct a grammatical error. 

c) Section 240.106 Determination of Violation 

This section was revised to remove the references to the repealed IM240 test 

standards, and to correct a grammatical error. 

d) Section 240 .I 07 Incorporations by Reference 

This section was revised to remove the incorporation by reference applicable to 

the repealed IM240 test. 

e) Section 240.151 Applicability 

4 
This section was revised to reference the proper VEIL. 

f) Section 240.153 Compliance Determination 

This section was revised to reflect the removal of the loaded pre-conditioning 

mode requirement in the steady-state idle exhaust test. 

g) Section 240.181 Applicability 

This section was revised to indicate that the on-road remote sensing exhaust 

emission test procedures have been adopted by the Agency.
