03-4261. Approval and Promulgation of Air Quality Implementation Plans; Michigan; Excess Emissions During Startup, Shutdown or Malfunction

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The EPA is proposing to approve several rule revisions for incorporation into Michigan's State Implementation Plan (SIP). The Michigan Department of Environmental Quality (MDEQ) submitted these revisions to EPA on September 23, 2002. They include rules to address excess emissions occurring during startup, shutdown or malfunction, as well as revisions to related definitions. 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 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 action in relation to this proposed rule. If we receive significant adverse comments, in writing, which we have not 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 on or before March 26, 2003.

ADDRESSES:

Send written comments to: Carlton Nash, Chief, Regulation Development Section, Air Programs Branch, (AR-18J), U.S. Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois, 60604.
