ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN158-1b; FRL-7626-8]


Approval and Promulgation of Implementation Plans; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: We are proposing to approve revisions to particulate matter 
(PM10) emissions regulations for U.S. Steel-Gary Works and 
U.S. Steel-Gary Coke Operations, located in Lake County, Indiana. The 
Indiana Department of Environmental Management requested on June 13, 
2003, and as supplemented on October 3, 2003, that EPA approve this 
State Implementation Plan (SIP) revision, as an amendment to 326 
Indiana Administrative Code (IAC) 6-1-10.1 and 326 IAC 6-1-10.2. The 
revisions to the rules reflect the closure of certain emission units, 
the addition of new emission units, and the installation of new control 
systems. These changes should result in decreased PM10 
emissions of approximately 350 tons per year. In the final rules 
section of this Federal Register, EPA is approving the State's SIP 
revision as a direct final rule without prior proposal because the 
Agency 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 receive no adverse comments in response to 
that direct final rule, we plan to take no further action on this 
proposed rule. If we receive significant adverse comments, we will 
withdraw the direct final rule and address all public comments received 
in a subsequent final rule based on this proposed rule. The EPA will 
not institute a second comment period on this document.

DATES: EPA must receive written comments on or before April 21, 2004.

ADDRESSES: Send written comments to: J. Elmer Bortzer, Acting Chief, 
Air Programs Branch, (AR-18J), Environmental Protection Agency, Region 
5, 77 West Jackson Boulevard, Chicago, Illinois 60604.
    Comments may also be submitted electronically or through hand 
delivery/courier, please follow the detailed instructions described in
