Description In 2009, the United States Environmental Protection Agency (EPA) designated part of Pierce
County as a nonattainment area. This designation is due to unhealthy levels of fine particle
pollution from 2006-2008 (74 FR 58688, Nov. 13, 2009). The Tacoma-Pierce County
Nonattainment Area (Nonattainment Area) (also known as the Wapato Hills-Puyallup River
Valley Nonattainment Area) covers most of the greater Tacoma area and the surrounding
communities within Pierce County’s urban growth area (UGA) west of State Route 167.
This State Implementation Plan (SIP) revision details Washington’s plan to improve air quality
in the Nonattainment Area. The revision includes:
A description of how the area will meet federal planning requirements for a
nonattainment area.
Local rules to help improve air quality.
Information on activities and projects carried out as part of the planning process for the
SIP revision.
REQUEST A COPY The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
