EPA is approving revisions to the Florida State Implementation Plan (SIP). These revisions were submitted to EPA through the Florida Department of Environmental Protection (FDEP) on January 8, 1993 and April 25, 1994. They revise regulations in Florida's SIP addressing new source review (NSR), non-control technology guidelines (non-CTG) for reasonably available control technology (RACT), and adds nitrogen oxide (NO<INF>x) as a RACT requirement in the South Florida nonattainment area in Florida's SIP. This plan has been submitted by the FDEP as an integral part of the program to achieve and maintain the National Ambient Air Quality Standards (NAAQS) for ozone, carbon monoxide, nitrogen dioxide and sulfur dioxide. These regulations meet all of EPA requirements and therefore EPA is approving the SIP revisions.
