Approval and Promulgation of Maintenance Plan Revisions; Wisconsin

AGENCY:

Environmental Protection Agency.

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a September 8, 2000 request from Wisconsin for a State Implementation Plan (SIP) revision of the Walworth County, Wisconsin ozone maintenance plan. The maintenance plan revision allocates a portion of the safety margin to the transportation conformity Mobile Vehicle Emissions Budget (MVEB) for the year 2007. EPA is approving the allocation of 0.5 tons per day of Volatile Organic Compounds (VOC) to the area's 2007 MVEB for transportation conformity purposes. This allocation will still maintain the total emissions for the area at or below the attainment level required by the transportation conformity regulations. 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:

Written comments must be received on or before November 27, 2000.
