02-29474. Approval and Promulgation of Implementation Plans; Indiana

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The EPA is proposing to approve revisions to particulate matter (PM) emissions regulations for Union Tank Car of Lake County, Indiana. The Indiana Department of Environmental Management (IDEM) submitted the revised regulations on April 30, 2002 and September 6, 2002 as an amendment to its State Implementation Plan (SIP). The revisions consist of relaxing the PM limits for one emissions unit; however, actual emissions will not increase, and the PM National Ambient Air Quality Standards (NAAQS) should be protected. EPA is approving revisions for Union Tank Car because complying with the current limits is infeasible, and because the revisions should not harm air quality.

DATES:

The EPA must receive written comments on this proposed rule by December 20, 2002.

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.
