The Environmental Protection Agency (EPA) is approving portions of State Implementation Plan (SIP) revisions and the Title V Operating Permit Program revisions submitted on May 19, 2017, by the State of Alabama, through the Alabama Department of Environmental Management (ADEM); submitted on November 29, 2017, by the State of Georgia, through the Georgia Environmental Protection Division (Georgia EPD); and submitted on September 5, 2017, by the State of South Carolina, through the South Carolina Department of Health and Environmental Control (SC DHEC). These revisions address the public notice rule provisions for the New Source Review (NSR) and Title V Operating Permit programs (Title V) of the Clean Air Act (CAA or Act) that remove the mandatory requirement to provide public notice of a draft air permit in a newspaper and that allow electronic notice ("e- notice") as an alternate noticing option. EPA is approving these revisions pursuant to the CAA and implementing federal regulations.
