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Ecology also requests EPA to remove a repealed rule, National Ambient Air Quality Standards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