RE: Revision to the Oregon State Implementation Plan – Adoption of the Eugene-Springfield PM₁₀ Maintenance Plan

Dear Mr. McLerran:

The Oregon Department of Environmental Quality (DEQ) requests approval of revisions to the Oregon State Implementation Plan (SIP) from the Office of Air, Waste, and Toxics, State and Tribal Air Programs Unit of the U.S. EPA, Region 10. Enclosed for your review is one hard copy of the amendments and one electronic copy of the amendments are saved on the disk included.

The Lane Regional Air Protection Agency (LRAPA) has jurisdiction over air quality in Lane County. Since DEQ has oversight authority to ensure LRAPA meets Clean Air Act requirements, proposed rule amendments are jointly presented by DEQ and LRAPA to the Environmental Quality Commission for adoption. The Environmental Quality Commission adopted the revisions to the SIP under OAR 340-200-0040 on December 15, 2011. DEQ submits these revisions to EPA as part of the SIP and pursuant to 40 CFR 51.104.

I certify that public notices were published in newspapers of general circulation on August 26, 2011 and in the Secretary of State’s Oregon Bulletin on September 1, 2011. The notices included a statement that adoption of the rules would revise the SIP. I further certify that a public hearing was held on September 26, 2011 in Springfield, Oregon.

Thank you for your assistance with these revisions to Oregon’s SIP. The staff contact for this submittal is Nicole Vick, SIP Coordinator at (503) 229-5946.

Sincerely,

Joni Hammond,

Deputy Director
