Approval and Promulgation of State Implementation Plans: Oregon

The EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the State of Oregon for the purpose of reducing the National Air Quality Standards (NAAQS) for carbon monoxide (CO). The SIP revision was submitted by the State to satisfy certain Federal Clean Air Act requirements for a basic motor vehicle inspection and maintenance (I/M) program in the Portland Metropolitan Service district and the Medford-Ashland Air Quality Maintenance Area. In the final rules section of this Federal Register, the 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 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 in response to this proposed rule, no further activity is contemplated in relation to this rule. If the EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period on this document. DATES: Comments
