The Environmental Protection Agency (EPA) is approving changes to the Kentucky State Implementation Plan (SIP) and the Kentucky Title V Operating Permit Program (Title V) submitted by the Commonwealth of Kentucky, through the Energy and Environment Cabinet (Cabinet) on August 12, 2020, and March 29, 2021. These revisions address the public notice rule provisions for the New Source Review (NSR), Federally Enforceable State Operating Permits (FESOP), and Title V programs of the Clean Air Act (CAA or Act) by providing for electronic notice ("e- notice") and removing the mandatory requirement to provide public notice of a draft air permit in a newspaper. EPA is approving these changes as they are consistent with the Clean Air Act (CAA or Act) and implementing Federal regulations.
