Should a distributor or blender wish to alter the parameters of RFG purchased from others by adding a blending component, are there limitations and/or restrictions on this type of activity? For example, in the Spring, will it be permissible to add a low-pressure blending component to gasoline in order to control volatility? Also, will it be permissible to blend octane deficient gasoline with an octane blending
component to restore octane to specification? If blending is allowed can only the end product be tested and certified or is it necessary to certify each blending step? Is blending in the above manner restricted to companies who have a history of blending gasoline or will the uninitiated also be permitted to blend components?See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The addition of a blendstock to certified RFG would result in the blender becoming a refiner under the RFG regulation. Refiners must establish a baseline, register with EPA and comply with all the testing, certification and other refiner…

Section 80.70 lists for Virginia the county of Richmond as an opt-in and excludes the city of Richmond. Is this a typographical error?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Yes. The city of Richmond is considered opted-in, not the county of Richmond. (7/1/94) This question and answer was posted at

If for the winter model an RVP of 8.7 has to be used when calculating emissions, what is the purpose of the RVP limits being 6.4 to 11 psi for conventional gasoline?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Some valid range limits must apply to conventional gasoline because even in summer months the RVP varies widely. The Complex Model contains statistically derived regression equations whose accuracy decreases dramatically when they are used outside of the valid…

If, in a splash blending situation, the terminal is not an oxygenate blender, would it handle the RBOB as an intermediate owner and transfer title of the RBOB to the exchange customer with the restriction that it only be sold to another intermediate owner of an EPA registered oxygenate blender? Would the exchange company, carrier, and owner of the blended product be responsible for the oxygenate blender oversight provisions and not the terminal operator?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . If a terminal does not meet the oxygenate blender definition, the answer to both questions is "yes." (7/1/94) This question and answer was posted at

If RFG is sold outside of an RFG area, are there any labeling changes, physically on the pump, that will be required?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . There are no pump labeling requirements under the RFG program, either inside or outside RFG covered areas. However, a mixture of conventional gasoline and RFG may not be sold as reformulated gasoline. Parties, therefore, should only sell gasoline…

If a refiner produces only conventional gasoline, what is the purpose of the added burden of testing, auditing, documentation, and general compliance requirements? Since there is only conventional gasoline produced, there can be no dumping. Also, if the EPA is concerned with other companies dumping into our conventional gasoline pool by selling us blendstocks, the blendstock accounting section would prohibit this. Thus, we come back to the question, "What is EPA's intent with the baseline and compliance requirements for conventional gasoline refiners?" Can the EPA exempt refiners from the accounting requirements for conventional gasoline? The EPA could exempt conventional gasoline reporting for a baseline volume; however, this implies that the EPA has a hidden agenda to control the future quality, if not the current quality, of conventional gasoline. Is it possible to petition the EPA for an exemption to the accounting and compliance requirements for conventional gasoline?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The Clean Air Act requires that all conventional gasoline on average be at least as clean as it was in 1990 regardless of who produces the conventional gasoline. Therefore, all refiners and importers are subject to requirements that…

If a purchased lot of certified RFG is combined with another lot of fungible certified RFG in a terminal, and a portion of the mixture is then sold to a third party, what form would the product transfer documentation take? Would it be necessary to convey documentation on a pro rata basis to all purchasers of the blended material?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . There is no specific form or required format for the produce transfer document (PTD) information. It should be included on the documents used to memorialize the transfer of the fuel and should reflect the amount and type of…
