ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[IN100-1b, IN120-1b; FRL-6728-1]


Approval and Promulgation of Implementation Plans; Indiana

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve revisions to total suspended 
particulate (TSP) and sulfur dioxide (SO2) emissions 
regulations for National Starch and Chemical Company (National Starch), 
and TSP regulations for Allison Transmission (Allison). Both of these 
facilities are located in Marion County, Indiana. The Indiana 
Department of Environmental Management (IDEM) submitted the revised 
regulations on February 3, 1999, August 30, 1999, and May 17, 2000, as 
amendments to its State Implementation Plan (SIP). The revisions 
include the relaxation of some limits, the tightening of one limit, and 
the elimination of limits for several sources which are no longer 
operating. The revisions also include the combination of annual 
emissions limits for several boilers, and recordkeeping requirements. 
These SIP revisions result in an overall decrease in allowed TSP 
emissions of about 406 tons per year for National Starch, and no change 
in overall annual emissions for Allison. Air quality modeling analyses 
conducted by IDEM show that the maximum daily and annual impacts of 
these SIP revisions are below established significance levels. 
Therefore, these SIP revisions will not have an adverse effect on air 
quality.

DATES: EPA must receive written comments by September 1, 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.
