Notice of Final Rulemaking: Regulation of Fuel and Fuel Additives: Reformulated Gasoline Requirements for the Atlanta Covered Area (published March 14, 2014)
In this Final Rule, EPA is determining that the Atlanta metro area is no longer a federal reformulated gasoline (RFG) covered area and there is no requirement to use federal RFG in the Atlanta area. The State requested removal from the federal RFG program. EPA has determined that the State’s request is appropriate in light of progress the State has made in attaining the ozone national Ambient Air Quality Standard without the use of RFG, and in light of the State fuel program that has covered the Atlanta metro area since the early 2000’s known as the “Georgia Fuel Program.” This Final Rule does not alter in any way the Georgia Fuel Program which currently applies in a 45-county area inclusive of the Atlanta metro area.

Modification of Baselines for Gasoline Produced or Imported for Use in Hawaii, Alaska, and U.S. Territories (published October 25, 2007)
This rule finalizes modifications to the Reformulated Gasoline program's conventional gas baseline regulations and to the Mobile Source Air Toxics regulations to allow refiners and importers of gasoline produced or imported for use in Hawaii, Alaska, Puerto Rico, and the U.S. Virgin Islands to petition EPA to change the way in which they calculate emissions from such gasoline.

Regulation of Fuel and Fuel Additives: Refiner and Importer Quality Assurance Requirements for Downstream Oxygenate Blending and Requirements for Disposition of Pipeline Interfaces (published June 2, 2006)
EPA issued a direct final rule to allow refiners and importers of reformulated gasoline blendstock for oxygenate blending (RBOB) the option to use an alternative method to conduct quality assurance sampling and testing at downstream oxygenate blending facilities. The rule also largely codifies existing guidance for compliance by transmix processors and blenders with requirements for gasoline content standards, recordkeeping, sampling and testing. These modifications provide additional flexibility to refiners and importers supplying RBOB to be blended with ethanol and to refiners who process transmix or blend transmix in gasoline.
Regulation of Fuel and Fuel Additives: Removal of Reformulated Gasoline Oxygen Content Requirement (published May 8, 2006)
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.

Direct Final Rules and Notice of Proposed Rulemakings:
Removal of Reformulated Gasoline Oxygen Content Requirement (National) and Revision of Commingling Prohibition to Address Non-Oxygenated Reformulated Gasoline (National) (published February 22, 2006)
Removal of Reformulated Gasoline Oxygen Content Requirement for California Gasoline and Revision of Commingling Prohibition to Address Non-Oxygenated Reformulated Gasoline in California (published February 22, 2006)
These two rules amend the RFG regulations to remove the oxygen content requirement for RFG. Because the compliance date for the removal of the oxygen requirement is different for gasoline sold in California than for gasoline sold in the rest of the country, we are publishing two separate rules:
- One rule removes the oxygen content requirement for RFG sold nationally (effective on May 6, 2006).
- The other rule removes the oxygen content requirement for RFG sold in California (effective 60 days from publication of the rule); and
These rules also revise a current prohibition against commingling ethanol-blended VOC-controlled RFG with VOC-controlled RFG produced using other oxygenates. The revision is to prohibit commingling ethanol-blended VOC-controlled RFG with non-oxygenated VOC-controlled RFG, except under certain limited circumstances.

Direct Final Rule: Modifications to Standards and Requirements for Reformulated and Conventional Gasoline Including Butane Blenders and Attest Engagements (published December 2, 2005):
This rule modifies the reformulated and conventional gasoline regulations to correct technical errors, clarify provisions and codify certain guidance previously issued by EPA in question and answer guidance documents.

Alternative Test Method for Olefins in Gasoline
This final rule allows for an additional alternative test method for olefins in gasoline, ASTM D6500-05. The allowance of this additional alternative test method will provide more flexibility to the regulated industry.

Gasoline and Diesel Fuel Test Methods (published February 6, 2009)
On December 8, 2008, a direct final rule and parallel notice of proposed rulemaking were published in the Federal Register (73 FR 74350 and 73 FR 74403, respectively) to update our motor vehicle fuels programs regulations for several test methods and to provide for an additional alternative test method for olefins in gasoline, ASTM D6550. We subsequently received an unanticipated adverse comment on the provision to allow the additional alternative test method for olefins in gasoline at 40 CFR 80.46(b)(2)(i) and 40 CFR 80.46(h)(1)(iii). We are issuing this notice to withdraw the provisions in the direct final rule on which we received adverse comment. The test method update provisions for which we did not receive adverse comment will become effective on February 6, 2009, as provided in the December 8, 2008, direct final rule.
