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.
Response to Petition From New Jersey Regarding SO2
In this action, EPA proposes to make a finding that the coal- fired Portland Generating Station (Portland Plant) in Upper Mount Bethel Township, Northampton County, Pennsylvania, is emitting air pollutants in violation of the interstate transport provisions of the Clean Air Act (CAA or Act). Specifically, EPA is proposing to find that emissions of sulfur dioxide (SO2) from the Portland Plant significantly contribute to nonattainment and interfere with maintenance of the 1-hour SO2 national ambient air quality standard (NAAQS) in New Jersey. This finding is proposed in response to a petition submitted by the State of New Jersey Department of Environmental Protection (NJDEP) on September 17, 2010. In this action, EPA is also proposing emission limitations and compliance schedules to ensure that the Portland Plant will no longer significantly contribute to nonattainment, and no longer interfere with maintenance of the 1- hour SO2 NAAQS, thereby permitting continued operation of the Portland Plant beyond the 3-month limit established by the CAA for sources subject to such a finding.
