## Abstract

The Environmental Protection Agency (EPA) is approving a revision to the Idaho Regional Haze State Implementation Plan (SIP) submitted by the State on June 28, 2016. Idaho submitted its Regional Haze Progress Report ("progress report" or "report") and a negative declaration stating that further revision of the existing regional haze SIP is not needed at this time. Idaho submitted both the progress report and the negative declaration in the form of implementation plan revisions as required by Federal regulations. The progress report addresses the Federal Regional Haze Rule requirements under the Clean Air Act to submit a report describing progress in achieving reasonable progress goals established for regional haze and a determination of the adequacy of the State's existing plan addressing regional haze.
