ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN105-1b; FRL-6720-1]


Approval and Promulgation of Implementation Plan; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve Indiana's State Implementation 
Plan (SIP) revision request to control emissions of volatile organic 
compounds (VOCs) from steel mill sinter plants in Lake and Porter 
Counties. The Indiana Department of Environmental Management (IDEM) 
submitted the SIP revision request on April 6, 1999. The revision 
applies to integrated steel mills and provides for seasonal limits on 
emissions of VOCs. VOC emissions are a precursor of ground-level ozone, 
commonly known as smog. High ozone levels are detrimental to human 
health and contribute to upper respiratory ailments such as asthma. In 
the Final Rules section of this Federal Register, EPA is approving as 
described herein, 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 activity in relation to this 
proposed rule. If EPA receives significant adverse comments, in 
writing, which have not been addressed, 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 by August 4, 2000.

ADDRESSES: You should mail written comments 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.
    You may inspect copies of the State submittal and EPA's analysis of 
it at: Regulation Development Section, Air Programs Branch (AR-18J), 
U.S. Environmental Protection Agency, Region 5, 77 West Jackson 
Boulevard, Chicago, Illinois 60604.

FOR FURTHER INFORMATION CONTACT: Francisco J. Acevedo, Environmental 
Protection Specialist, Regulation Development Section, Air Programs
