#  Approval and Promulgation of Implementation Plans; IN

**AGENCY:**

Environmental Protection Agency (EPA).

**ACTION:**

Proposed rule.

**SUMMARY:**

The EPA is proposing to approve revisions to particulate matter (PM) regulations for Rolls-Royce Allison (Rolls-Royce), formerly Allison Engine Company. This facility is located in Marion County, Indiana. The Indiana Department of Environmental Management (IDEM) submitted the revised regulations on August 31, 2000 as a requested amendment to its State Implementation Plan (SIP). The revisions consist of a name change for the company and the addition of a provision that allows the facility to use landfill gas as an alternate fuel. These requested SIP revisions do not change Rolls-Royce's emissions limits.

**DATES:**

The EPA must receive written comments on this proposed rule by July 12, 2001.

**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.
