The Pollution Control Board proposed to amend 35 Ill. Admin. Code § 240, Mobile Sources. Changes would exempt model year 1995 and older vehicles from inspection, replace the transient loaded mode emissions inspection test with the on-board diagnostic inspection test as the primary test, and maintain the steady-state idle exhaust gas analysis and evaporative system integrity emissions tests as secondary emissions tests. http://www.cyberdriveillinois.com/departments/index/register/register_volume35_issue1.pdf pp. 129-168.
