Abstract
The Environmental Protection Agency (EPA) is finalizing approval of revisions to the Alabama State Implementation Plan (SIP), submitted by the State of Alabama, through the Alabama Department of Environmental Management (ADEM), via two letters dated May 7, 2012, and August 27, 2018. The SIP revisions relate to the State's Prevention of Significant Deterioration (PSD) permitting regulations. In particular, the revisions add a definition of "replacement unit" and provide that a replacement unit is a type of existing emissions unit under the definition of "emissions unit." This action is being taken pursuant to the Clean Air Act (CAA or Act).
