Approval and Promulgation of Implementation Plan; Wisconsin

요약

United States Environmental Protection Agency (USEPA) proposes full approval of Wisconsin's 1990 base year ozone (O 3) emission inventory as a revision to the Wisconsin State Implementation Plan (SIP) for O 3. The inventory was submitted by the State of Wisconsin to satisfy a Federal requirement that those States containing O 3 nonattainment areas (NAAs) classified as marginal to extreme submit inventories of actual O 3 season emissions from all sources in accordance with USEPA guidance. In the final rules section of this Federal Register, USEPA is approving the State's SIP revision as a direct final rule without prior proposal, because the Agency views this as a noncontroversial revision amendment 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 on this direct final rule, no further activity is contemplated in relation to this proposed rule. If USEPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. USEPA will not institute a second comment period on this docu
