Through the 1990 amendments to the Clean Air Act (CAA), Congress required EPA to publish rules requiring that gasoline sold in certain areas be reformulated to reduce vehicle emissions of toxic and ozone-forming compounds. EPA published rules for the certification and enforcement of reformulated gasoline (RFG) and provisions for non- reformulated or conventional gasoline on February 16, 1994. In a final rule published on December 31, 1997, EPA took final action on several revisions to the RFG/conventional gasoline regulations. However, the December 31, 1997 final rule included two clerical errors. One of these errors involved an incorrect designation in the amendatory language published in the Federal Register, which resulted in the inadvertent deletion of certain regulatory text when the regulation was published in the Code of Federal Regulations (CFR) on July 1, 1998. The other was a typographical error in a revised chart for Phase II Complex Model Averaged Standards for RFG. The correct text for both appears in earlier editions of the CFR. This action corrects these errors in the current CFR. This action does not make any substantive changes to the RFG/conventional gasoline regulations.
