EPA's Proposed Approval

On January 11, 2018, the EPA signed its proposed approval of Idaho’s request to revise the State Implementation Plan (SIP) in regard to agricultural residue burning.

The proposed approval finds that Idaho’s requested SIP revision meets the requirements of the Clean Air Act.

If approved as proposed, the revision would give Idaho more flexibility in declaring burning days, allowing them to burn on more good smoke dispersion days than previously allowed under the existing SIP.

The Federal Register notice and Technical Support Document contain detailed information on our proposed action.

Public Comments

EPA’s proposed action included a 30-day public comment period that ended February 21, 2018. EPA will make a final determination on Idaho's request after evaluating all comments received (see link below to view comments).
