Abstract
EPA is approving the State of Illinois' request to redesignate to attainment the Lake Calumet (Southeast Chicago) area currently designated as nonattainment of the National Ambient Air Quality Standard (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM-10). We are also approving the Lake Calumet maintenance plan, submitted by the Illinois Environmental Protection Agency (IEPA) on August 2, 2005, and as supplemented on September 8, 2005, as a revision to the PM-10 State Implementation Plan (SIP) for this area.
