          - 40 CFR Parts 52 and 81 
          - [R05-OAR-2005-IL-0002; FRL-7972-8] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

EPA is proposing to approve the State of Illinois' request to redesignate to attainment the Lyons Township (McCook) 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 proposing to approve the Lyons Township maintenance plan, submitted by the Illinois Environmental Protection Agency (IEPA) on August 2, 2005, as a revision to the PM-10 State Implementation Plan (SIP) for this area. 

                        In the final rules section of this                         **Federal Register**                        , EPA is approving the SIP revision as a direct final rule without prior proposal, because EPA views this as a noncontroversial revision and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If we do not receive any adverse comments in response to these direct final and proposed rules, we do not contemplate taking any further action in relation to this proposed rule. If EPA receives adverse comments, we will withdraw the direct final rule and will respond to all public comments in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time.

Written comments must be received on or before October 24, 2005.
