ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[IN73-1b; FRL-5808-1]


Approval and Promulgation of Implementation Plan; Indiana

AGENCY: Environmental Protection Agency (USEPA).

ACTION: Proposed rule.

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

SUMMARY: The USEPA is proposing to approve the State Implementation 
Plan (SIP) revision request submitted by the Indiana Department of 
Environmental Maintenance (IDEM) on October 2, 1996. In the October 2 
submittal, IDEM requested a SIP revision to eliminate references to 
total suspended particulates (TSP) while maintaining the existing 
opacity requirements. In the final rules section of this Federal 
Register, USEPA is approving the State's SIP revision as a direct final 
rule without prior proposal because the agency views this as a 
noncontroversial SIP revision and anticipates no adverse comments. A 
detailed rationale for the approval is set forth in the direct final 
rule. If no adverse comments are received in response to this proposed 
rule, no further activity is contemplated in relation to this rule. If 
USEPA receives adverse comments, the direct final rule will be 
withdrawn and all public comments received will be addressed in a 
subsequent final rule based on this proposed rule. USEPA will not 
institute a second comment period on this action. Any parties 
interested in commenting on this action should do so at this time.

DATES: Comments must be received in writing by May 16, 1997.

ADDRESSES: Copies of the revision request are available for inspection 
at the following address: U.S. Environmental Protection Agency, Region 
5, Air and Radiation Division, 77 West Jackson Boulevard, Chicago, 
Illinois 60604. (It is recommended that you telephone Ryan Bahr, 
Environmental Engineer, at (312) 353-4366 before visiting the Region 5 
Office.)
    Written comments should be sent to: J. Elmer Bortzer, Chief, 
Regulation Development Section, Air Programs Branch (AR-18J), U.S. 
Environmental Protection Agency, 77 West Jackson Boulevard, Chicago, 
Illinois 60604.

FOR FURTHER INFORMATION CONTACT: Ryan Bahr, at (312) 353-4366.

SUPPLEMENTARY INFORMATION: See the information provided in the direct 
final action of the same title which is located in the Rules and 
Regulations Section of this Federal Register.

    Authority: 42 U.S.C. 7401-7671q.

    Dated: March 28, 1997.
