ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IL145-2, IL152-2; FRL-5890-1]


Approval and Promulgation of Implementation Plan; Illinois 
Designation of Areas for Air Quality Planning Purposes; Illinois

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule; extension of the public comment period.

-----------------------------------------------------------------------

SUMMARY: On July 22, 1997, the EPA published a proposed rule (62 FR 
39199) proposing limited approval and limited disapproval of the 
Granite City portion of a State Implementation Plan (SIP) revision 
request which was submitted by the State of Illinois on November 14, 
1995, May 9, 1996, June 14, 1996, and February 3, 1997, 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 proposed limited approval and limited disapproval action entails 
approval of the submitted regulations into the Illinois SIP for their 
strengthening effect, and disapproval of the submittal for not meeting 
all of the commitments of the conditional approval. All of the 
deficiencies were corrected, except that Illinois failed to provide an 
opacity limit for coke oven combustion stacks which is reflective of 
their mass limits. In the same notice, the EPA also proposed to 
disapprove Illinois' March 19, 1996, and October 15, 1996, request to 
redesignate the Granite City area to attainment for PM because the area 
does not have a fully approved implementation plan. The EPA is 
announcing a 60-day extension of the public comment period on the July 
22, 1997, proposed rule.

DATES: Written comments on the July 22, 1997, proposed rule must be 
received on or before October 20, 1997.

ADDRESSES: Written comments should be mailed to: J. Elmer Bortzer, 
Chief, Regulation Development Section, Air Programs Branch (AR-18J), 
U.S. Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604.
