Subject: The Oregon Department of Environmental Quality (DEQ) is proposing to revise the PM10 attainment plan and establish a PM10 maintenance plan for the Medford-Ashland Air Quality Maintenance Area (AQMA). The combined attainment and maintenance plan will demonstrate that the AQMAhas met, and will continue to meet, National Ambient Air Quality Standards (NAAQS) for PM10 through at least the year 2015. The Department is also proposing amendments to air quality rules affecting new and expanding major industrial sources in the AQMA. The plan and supporting rule amendments will be presented for adoption to the Environmental Quality Commission (EQC) as an amendment to the State Implementation Plan (SIP), as required by the Clean Air Act (amends OAR 340-200-0040). If approved by the EQC, DEQ will submit the plans to the Environmental Protection Agency (EPA) for approval with a request that the legal status of the AQMA be revised from nonattainment to attainment for PM10.
