Regulation of Fuel and Fuel Additives: Removal of Reformulated Gasoline Oxygen Content Requirement

Rule Summary

EPA amended the RFG regulations to remove the oxygen content requirement and all provisions which were included in the regulations to ensure compliance with the oxygen content requirement. Because the Energy Policy Act of 2005 established different compliance dates for the removal of the RFG oxygen requirement in California and the rest of the country, EPA previously issued two Direct Final Rules (DFRs) and two accompanying Notices of Proposed Rulemaking (NPRMs) implementing the removal of the oxygen requirement.
