Ecology Recommends Designations and a Nonattainment Area for the 2006 PM2.5 Standard

The department of ecology (ecology) is holding a public hearing to receive comment on recommendations the state of Washington is considering submitting to the United States Environmental Protection Agency (EPA). These recommendations are on designations and a nonattainment area for the federal twenty-four-hour standard for fine particulate matter.

Background information: The EPA revised the air quality standard for fine particulate matter less than 2.5 microns in size (PM2.5) in 2006. The reason for changing the standard was to better protect public health. EPA changed the standard from 65 micrograms per cubic meter to 35 micrograms per cubic meter.

When EPA changes an air quality standard, states can make recommendations to EPA on whether areas in the state should be designated "attainment" (meeting the standard), "nonattainment" (not meeting the standard), or "unclassifiable" (there is not enough information to determine if the area meets the standard).

Ecology's recommendations: After examining EPA's monitoring data, ecology proposes to make the following recommendations:


Duwamish area of Seattle
Lake Forest Park

*South Tacoma
*The Puget Sound Clean Air Agency (PSCAA) developed the proposed nonattainment area for Tacoma, which is within PSCAA's jurisdiction, on the basis of the nine factors in EPA guidance and with input from a variety of organizations. The proposed area is the entire area within the Pierce County comprehensive urban growth area (CUGA), except for:

Areas to the south and southwest (including Fort Lewis and McChord Air Force Base), and
The area to the east along and east of the Puyallup River-White River valleys (including Sumner, Auburn, Pacific, Bonney Lake, and Orting).

Moose Lodge in Vancouver
S. 4th Avenue in Yakima
*Unclassifiable areas had monitors that were discontinued but restarted in January 2007.

Public hearing schedule: Ecology will hold a hearing to receive public comment on the draft PM2.5 recommendations and the proposed nonattainment area boundary on Wednesday, December 5, 2007, at 7:00 p.m., at the Pierce County Library and Administrative Center (PAC Building), 3005 112th Street E., Tacoma, WA 98446.
