ENVIRONMENTAL PROTECTION AGENCY

40 CFR Parts 52 and 81

[IN83-1b; FRL-5882-7]


Designation of Areas for Air Quality Planning Purposes; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is proposing to approve a redesignation request 
submitted by the State of Indiana on April 8, 1993, and supplemented on 
June 17, 1997. In this submittal, Indiana submitted a maintenance plan 
and requested that a portion of Vermillion County be redesignated to 
attainment of the National Ambient Air Quality Standard (NAAQS) for 
particulate matter with an aerometric diameter less than 10 micrometers 
(PM-10). 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 SIP 
revision and anticipates no adverse comments. A detailed rationale for 
the approval is set forth in the direct final rule. If no written 
adverse comments are received in response to this proposed rule, no 
further activity is contemplated in relation to this rule. If EPA 
receives written 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withdrawn and all public comments received will be addressed in a 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. 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.

DATES: Comments must be received in writing by September 25, 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 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, Environmental Engineer, 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: August 14, 1997.

Acting Regional Administrator.
