Puget Sound Clean Air Agency SIP Revision

The Washington State Department of Ecology (Ecology) is proposing to submit to the Environmental Protection Agency a revision of Washington’s air quality State Implementation Plan (SIP) proposed by the Puget Sound Clean Air Agency (PSCAA).  PSCAA has already adopted the rules in the proposed SIP revision into their air quality regulations (Regulation I).  Ecology proposes to include these revisions in the SIP to make them federally enforceable in PSCAA’s jurisdiction. No changes to the existing state or agency’s rules are being proposed.

The Ecology comment period will be October 21, 2019 to December 6, 2019.
