Air Plan Approval; OR; Portland, Medford, Salem; Clackamas, Multnomah, Washington Counties; Gasoline Dispensing Facilities

The Environmental Protection Agency (EPA) is taking direct final action to approve three state implementation plan (SIP) revisions submitted by the State of Oregon Department of Environmental Quality (Oregon or ODEQ) and a specific portion of a fourth SIP submittal identified in a supplementary letter. These SIP submittals primarily include rule amendments related to control measures for volatile organic compounds from gasoline dispensing facilities in the Portland- Vancouver, Medford-Ashland, and Salem-Keizer Area Transportation Study air quality management areas, as well as all of Clackamas, Multnomah, and Washington counties. The EPA received the SIP submittals from the ODEQ on February 5, 2009, November 1, 2010, May 25, 2011, and April 20, 2015, and the supplementary letter on September 18, 2015. The EPA is approving the SIP submittals because they are consistent with the requirements of the Clean Air Act (Act or CAA).
