The Environmental Protection Agency (EPA) proposes to approve a revision to the Idaho State Implementation Plan (SIP) submitted on May 4, 2022. The submission updates the incorporation by reference of the national ambient air quality standards and related planning and monitoring requirements into the Idaho air quality rules as of July 1, 2021. Idaho undertakes such updates regularly to ensure the state air quality rules and the federally enforceable Idaho SIP remain consistent with EPA air quality regulations over time.
