Regulation of Fuel and Fuel Additives: Refiner and Importer Quality Assurance Requirements for Downstream Oxygenate Blending and Requirements for Disposition of Pipeline Interfaces

Rule Summary

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.
