## Abstract

On November 14, 1995, May 9, 1996, June 14, 1996, February 1, 1999, and May 19, 1999, the State of Illinois submitted State Implementation Plan (SIP) revision requests to meet commitments related to our conditional approval of Illinois' May 15, 1992, SIP submittal for the Lake Calumet (Southeast Chicago), McCook, and Granite City, Illinois, Particulate Matter (PM) nonattainment areas. EPA is approving the SIP revision request as it applies to the Lake Calumet area, including the attainment demonstration for the Lake Calumet PM nonattainment area. The SIP revision request corrects, for the Lake Calumet PM nonattainment area, all of the deficiencies of the May 15, 1992, submittal (as discussed in the November 18, 1994, conditional approval notice). EPA is also removing the codification of the conditional approval and codifying the final portions of Illinois' part D plan for the Granite City, Lake Calumet, and McCook moderate PM nonattainment areas. EPA is approved the Granite City PM plan, effective May 11, 1998, and the McCook PM plan, effective November 9, 1998.
