Law of2005 (625 ILCS 5/13C-10 and 13C-20]. 

5) A Complete Description of the Subject') and Issues Involved: The Illinois Environmental 

Protection Agency's (Illinois EPA) proposal would amend Part 276 to ref1ect the 

adoption of the Vehicle Emissions Inspection Law of 2005 ("VEIL of 2005") (P .A. 94-

526) (625 ILCS 5113C), an amendment to the VEIL of 2005 (P.A. 94-848), and to. make 

·necessary improvements to the program. The VEIL of 2005 was a replacement for, and 

continuation of, the program established under the Vehicle Emissions Inspection Law of 

1995 ("VEIL of 1995") (625 ILCS 5/l3B). The VEIL of 2005 was modeled off of the 

VEIL of 1995, but added definitions relating to the on-board diagnostic ("OBD") 

inspection test;· exempted model year 1995 and older vehicles from inspection; replaced 

the transient loaded m.ode ("1M240") emissions test with the OBD test as the primary 

vehicle inspection test; maintained the steady-state idle exhaust gas analysis and 

evaporat.ive system integrity tests as secondary tests; revised the OBD test; revised 

waiver provisions; added a provision for vehicles located outside of the affected counties; 

removed the prohibition against contractor repairs; and made other additions. An 

amendment to the VEIL of 2005 provided that the owner of a subject vehicle must obtain 

an emission compliance certificate to demonstrate compliance and established a system 

of registration denial for vehicles in noncompliance with the inspection requirement. 
ILLINOIS REGISTER 

ENVIRONMENTAL PROTECTION AGENCY 

NOTICE OF PROPOSED AMENDMENTS 

The proposed amendments to Part 276 have been developed to retlect the VEIL of 2005. 

including an amendment thereto. Also, the proposed amendments have been developed 

to refiect improvements to the program. The proposed amendments remove definitions 

relating to the proposed removal of the IM240 emissions test, add new definitions and 

clarify other definitions. The amendments propose the removal of the IM240 emissions 

test procedures, related provisions, and all references thereto to reflect full 

implementation of OBD testing. The amendments require a subject vehicle owner to 

obtain, but not display or possess, an emissions compliance certificate in order to obtain 

or renew the subject vehicle's registration. The amendments specify the design of an 

emissions compliance certificate. The amendments remove all different rypes of 

inspectiori certificates or stickers and propose the use of a universal "emission 

compliance certificate." The amendments clarify the recordkeeping requirements 

relating to maintenance and calibrations perfom1ed. The amendments revise provisions 

relating to waivers, economic hardship, fleet self-testing; grievances, test notices, and 

reciprocity. The amendments propose a new section relating to the collection and 

reporting of repair facility data. The amendments propose a new section providing 

requirements for obtaining an emissions compliance certificate where the vehicle is 

located and being primarily operated outside the affected counties. The proposed 

amendments eliminate Table A and B relating to the IM240 test. Finally, the proposed 

amendments update and clarify other provisions in the rule. 

6) Published studies or reports, and sources of underlving data, used to compose this 

rulemaking: The Illinois EPA relied on various sources to compose this rulemaking. 

Copies of these sources are available for review with the Illinois EPA at 1021 N. Grand
