## Abstract

On November 14, 1995, and May 9 and June 14, 1996, the State of Illinois submitted State Implementation Plan (SIP) revision requests to meet commitments related to the conditional approval of Illinois' May 15, 1992, SIP submittal for the Lake Calumet (SE Chicago), McCook, and Granite City, Illinois, Particulate Matter (PM) nonattainment areas. The EPA is approving the SIP revision request as it applies to the McCook area, including the attainment demonstration for the McCook PM nonattainment area. The SIP revision request corrects, for the McCook PM nonattainment area, all of the deficiencies of the May 15, 1992, submittal (as discussed in the November 18, 1994, conditional approval notice). This document also revises the codification of the conditional approval to remove issues which have been resolved. No action is being taken on the submitted plan revisions for the Lake Calumet area at this time; they will be addressed in a separate rulemaking action. Approval of the Granite City PM plan became effective on May 11, 1998 (see 63 FR 11842).
