Summary

The Environmental Protection Agency (EPA) proposes to approve revisions to the Idaho State Implementation Plan (SIP) submitted on May 8, 2023 and May 13, 2024. The SIP submissions include changes designed to streamline the Idaho air quality regulations by repealing outdated provisions, striking duplicative terms, and simplifying rule language. The submissions also update the adoption by reference of specific Federal standards and reference methods. The EPA proposes to determine that the submitted changes to the Idaho SIP are consistent with Clean Air Act requirements.
