Description Ecology submits a new rule to EPA for inclusion in the
Washington State Implementation Plan (SIP). The new rule – Ambient Air Quality Standards, Chapter 173-476 WAC – incorporates the current National Ambient Air Quality Standards for criteria pollutants. These standards are federally-required and apply statewide. Ecology also requests EPA to remove a repealed rule – National Ambient Air Quality Standards for Particulate Matter, Chapter 173-470 WAC – from the SIP.
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.
