If I have a renewable fuel that was assigned a specific Equivalence Value in regulation Section 80.1115, but I don't think that Equivalence Value is right for my product, what options do I have?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Producers or importers of renewable fuel may submit a petition to the EPA requesting a different Equivalence Value from that assigned in the regulations. However, the petition must use the calculation methodology described in regulation Section 80.1115(d). In short…

If a new area decides to opt-in to the reformulated gasoline program, what determines the effective date that reformulated gasoline must be supplied to that area?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The effective date of the program in any area which opts into the program is January 1, 1995, or one year after EPA receives the request to include the area in the program, whichever is later. EPA will announce…

If an independent lab temporarily cannot run a required test, may the independent lab use a substitute lab for the test until the independent lab regains its testing capacity? May a refiner use one independent lab to collect samples at a refinery, and another independent lab to analyze those samples? If a second lab is used, must the primary independent lab notify EPA of the role of the second lab?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. An independent lab may use a second lab to collect samples or perform required tests, provided that: (1) the second lab is independent as defined in § 80.65(f)(2)(iii); (2) the primary independent lab is responsible for the quality of…

If an obligated party (a refiner) imports non-denatured ethanol and denatures it, is the refiner considered a renewable fuel producer and is the refiner obligated to establish RIN numbers and file quarterly reports for the ethanol it denatures?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The party would be identified as a renewable fuel importer rather than a renewable fuel producer, and would need to establish RIN numbers and file reports required of an importer. The party in this example would also be required…
-
If an importer registers in a PADD, may the importer use a starting point other than zero, within the range of valid batch numbers, for generating the sequential batch numbers at each of its import facilities?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Yes. As long as no batches are assigned duplicate numbers this would be acceptable. (7/1/94) This question and answer was posted at

If a party buys a batch of ethanol, and through testing determines that the ethanol is synthetic (non-renewable), what happens to the RINs?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. If a volume of renewable fuel for which RINs have been generated is found to not be a valid renewable fuel under the RFS program, then the associated RINs are likewise deemed invalid. See regulation Section 80.1131. If a…

If one company acquires foreign product in transit, then sells it to a second company while still in transit, who is the importer?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The importer is the party identified above, the party primarily liable for payment of duties for Customs purposes when the gasoline enters the United States. (7/1/94) This question and answer was posted at

If an oxygenate blender adds oxygenate only to conventional gasoline downstream of the refinery, please confirm that the oxygenate blender is not considered a "refiner" and therefore is not subject to record keeping, reporting, or attest engagement requirements.
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. This party would not be considered a "refiner" for purposes of the anti-dumping requirements, and is not required to meet the anti-dumping requirements specified in the question. (7/1/94) This question and answer was posted at

If a party identifies RFG that is out of spec for a downstream standard, and the party wants to bring the gasoline back into spec by blending it with other RFG or with blendstock, must the party be registered with EPA as a refiner, and must the party meet all the requirements that apply to refinery operations for this blending activity?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. If RFG at a location downstream of the refinery or import facility level is found to violate a downstream standard, a violation of the RFG requirements has occurred for which various parties will be liable, and for which penalties…
-
If the oxygenate program remains in effect in California after CARB fuel in 1996, would we still need to identify the type and amount of oxygenate to meet the oxygenated program transfer document requirements? or will we be exempt for these record keeping/transfer document requirements?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. With regard to RFG product transfer documentation requirements as applied to California gasoline, § 80.81(c)(9) of the regulations exempts California gasoline (as defined in § 80.81(a)(2)) produced or imported subsequent to March 1, 1996 from the product transfer documentation…

If re-transmission is necessary due to fault on EPA's part, why won't EPA pay for re-transmission?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. EPA will take all reasonable steps to properly maintain equipment, services, and testing necessary to effectively and reliably send and receive documents via EDI. Although EPA is unable to pay for re-transmission costs, we will exercise the highest degree…

If a refiner elects to use composite sampling and testing as provided for in the regulations, may the refiner use composite sampling for one parameter and perform the required tests for the other relevant properties?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Section 80.101(i) requires refiners to separately sample each batch of gasoline and blendstocks that are included in anti-dumping compliance calculations, and either separately analyze each sample, or under § 80.101(i)(2), analyze a volume-weighted composite of the samples collected up…

If a refiner produces "specified RBOB" for 3.5% oxygenate (for example, 10% vol EtOH) blending, and an oversight program shows that the downstream blender is adding less than 10% EtOH, who is liable for a compliance violation? Is there a violation at all at all if the actual finished blend still meets the RFG specs? For example, if RBOB is formulated to meet RFG with 8% EtOH, but the refiner sells it as "10% EtOH" RBOB (and uses the 10% in the calculation of its non-oxygenate parameters) to encourage maximum ROXY credits, does an actual blend with 8% EtOH cause a violation?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. If the downstream oxygenate blender is adding oxygenate in amounts other than that specified by the refiner of the RBOB, the blender would be liable for a violation of the regulations regardless of whether the gasoline meets the downstream…
