Air Plan Approval; Washington; Spokane Regional Clean Air Agency, General Air Quality Regulations

요약

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 Spokane Regional Clean Air Agency (SRCAA). In 2021, the EPA approved a comprehensive update to the SRCAA general air quality regulations in the SIP, which include new source review permitting requirements as well as other general requirements for sources regulated under SRCAA's jurisdiction. In this action, the EPA proposes to approve additional updates to the SRCAA general air quality regulations promulgated since our comprehensive approval in 2021.
