Approval and Promulgation of Implementation Plans; Oregon; Interstate Transport of Pollution; Significant Contribution to Nonattainment and Interference With Maintenance Requirements
EPA is proposing to approve a portion of the State Implementation Plan (SIP) revision submitted by the State of Oregon for the purpose of addressing the interstate transport provisions of Clean Air Act (CAA) section 110(a)(2)(D)(i)(I) for the 1997 8-hour ozone National Ambient Air Quality Standards (NAAQS or standards) and the 1997 fine particulate matter (PM2.5) NAAQS. Section 110(a)(2)(D)(i) of the CAA requires that each State have adequate provisions to prohibit air emissions from adversely affecting air quality in other States through interstate transport. EPA is proposing to approve Oregon’s SIP revision for the 1997 8-hour ozone and 1997 PM2.5 NAAQS as meeting the requirements of CAA section 110(a)(2)(D)(i)(I) to prohibit emissions that will contribute significantly to nonattainment of the these standards in any other State and to prohibit emissions that will
interfere with maintenance of these standards by any other State.
