Approval and Promulgation of Implementation Plans; Georgia: Revisions to Definitions and Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is proposing to approve portions of the State Implementation Plan (SIP) revisions submitted by the State of Georgia, through the Georgia Department of Natural Resources' Environmental Protection Division (GA EPD) on August 30, 2010, December 15, 2011, and November 12, 2014. The SIP submittals include changes to GA EPD's air quality rules that, among other things, modify definitions and modify the ambient air standards for fine particulate matter. The portions of the SIP revisions that EPA is approving are consistent with the requirements of the Clean Air Act (CAA). In the Final Rules Section of this Federal Register, EPA is approving these portions of the SIP revisions as a direct final rule without prior proposal because the Agency views these as a noncontroversial submittals and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule.
