## Abstract

EPA is approving revisions to the Mississippi State implementation plan (SIP) submitted on September 30, 1996, by the State of Mississippi through the Department of Environmental Quality (MDEQ). These SIP revisions incorporate changes to Regulation APC-S-1, ``Air Emission Regulations for the Prevention, Abatement, and Control of Air Contaminants,'' and Regulation APC-S-5, ``Regulations for the Prevention of Significant Deterioration of Air Quality.'' The proposed revisions to APC-S-1 incorporate amendments to state open burning restrictions and prohibitions to ensure consistency with federal solid waste disposal regulations as specified in 40 CFR Part 257. The proposed revisions to APC-S-5 incorporate revisions to the state prevention of significant deterioration of air quality regulations to update the adoption by reference in APC-S-5 of the amendments and revisions to the federal regulations promulgated in 40 CFR 52.21 and 51.166 of August 22, 1996.
