Regulation of Fuels and Fuel Additives: Modifications to Standards and Requirements for Reformulated and Conventional Gasoline Including Butane Blenders and Attest Engagements

EPA is taking direct final action on certain modifications to the reformulated and conventional gasoline regulations. Based on experience gained since the promulgation of these regulations, EPA proposed these modifications along with various others in a Notice of Proposed Rulemaking (NPRM) published on July 11, 1997. In final rules published on December 31, 1997, and December 28, 2001, EPA took final action on several of the modifications proposed in the July 11, 1997 NPRM. Today's direct final action would finalize many of the remaining proposed modifications. The modifications in today's direct final rule correct technical errors, clarify certain provisions, and codify guidance previously issued by the Agency. This rule also makes several minor technical corrections to the RFG rule which were not included in the July 11, 1997 proposal, and makes two minor technical corrections to the Tier 2 gasoline sulfur rule. The emissions benefits achieved from the RFG and conventional gasoline programs will not be reduced as a result of this direct final rule.
