Approval and Promulgation of Air Quality Implementation Plans; California; Monterey Bay Region 8-Hour Ozone Maintenance Plan

Riepilogo

On December 19, 2007, the State of California submitted an 8- hour ozone maintenance plan for the Monterey Bay Unified Air Pollution Control District and requested that EPA approve the plan as a revision to the California State Implementation Plan (SIP). In this action, EPA is proposing to approve the maintenance plan. In the "Rules and Regulations" section of this Federal Register, EPA is approving the State's request for approval of the maintenance plan as a direct final rule without prior proposal because the Agency views the maintenance plan and SIP revision as non-controversial and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.
