The Environmental Protection Agency (EPA) is proposing to approve revisions to the Washington State Implementation Plan (SIP) that were submitted by the Department of Ecology (Ecology) in coordination with the Yakima Regional Clean Air Agency (YRCAA). In 2014, 2015, 2016, and 2020, the EPA approved revisions to the General Regulations for Air Pollution Sources promulgated by Ecology in the Washington Administrative Code (WAC). In this action, the EPA proposes to update the SIP for YRCAA's jurisdiction to reflect these changes to the WAC. We also propose to update certain YRCAA regulations currently in the SIP, remove obsolete regulations, and approve a small set of YRCAA regulations to replace or supplement the corresponding WAC regulations for sources in YRCAA's jurisdiction.
