Abstract
The EPA is approving the remaining portions of a vehicle inspection and maintenance (I/M) State Implementation Plan (SIP) revision submitted by the State of Illinois on June 29, 1995, which were conditionally approved by EPA on June 25, 1996. The final approval of the conditionally approved portions of the plan is based on the State's June 21, 1997, and December 9, 1998, submittals of additional documentation addressing the requirements of EPA's conditional approval. This revision provides for the adoption and implementation of an enhanced I/M program in both the Chicago severe ozone nonattainment area and the East St. Louis moderate ozone nonattainment area.
