For a refiner producing conventional gasoline, may oxygenate added at a nonproprietary terminal be included in the determination of the conventional gasoline properties, provided the refiner has a quality assurance program at the terminal to ensure the oxygenate was added?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . A refiner may include oxygenates added to conventional gasoline by a party downstream of the refinery, including a "non-proprietary terminal," provided the refiner has a program in place to ensure that the oxygenate is added as reported by…

A refiner produces a tank of conventional gasoline on December 30, 1995. The tank is not shipped until January 2, 1996. Must the refiner include this batch in his 1995 volume or does he have the option of including it in either 1995 or 1996?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Compliance for a particular batch of conventional gasoline is based on the date the batch is produced, not shipped. As a result, the batch identified in the question would be included in the 1995 compliance calculations. However, the…

Refiners and oxygenate blenders who produce averaged reformulated gasoline must report which covered areas products have been distributed to by each facility. How are these areas to be determined?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Unless a refiner or oxygenate blender has specific and detailed information indicating otherwise, it must be assumed that products have been delivered to all covered areas serviced by the distribution system(s) used. A list of covered areas as…

Referring to § 80.69, will EPA consider alternative testing approaches if extreme circumstances prohibit testing as defined by EPA? As an example, the situation may exist where an oxygenate blender is prohibited by state law from taking truck samples. In this case the only way to comply with EPA sampling requirements would be to somehow sample the batch as it is being dropped at its destination. This may be prohibited if the terminal only sells to jobbers. In addition, product sampled from trucks or retail outlets does not necessarily reflect product blended by the oxygenate blender. Residual fuel in trucks and or retail tanks will mix with the terminal product before sampling. A quality oversight of the RBOB in conjunction with meter readings showing proper delivery of oxygenate volumes may better reflect a terminal's product? How does the EPA plan to test in these situations?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . EPA will consider extreme circumstances that may prohibit sampling and testing as required by section 80.69. However, to date, EPA is not aware of such circumstances. Some state laws may prohibit the opening of truck compartment hatches during…

Recently, a natural gas pipeline condensate was refused at a fractionator. The condensate met all fractionator specifications and did not contain any hazardous materials. The operator of the fractionator advised that their facility could only take in previously manufactured materials as a direct result of the anti-dumping rules contained in the reformulated gasoline regulations. Within the anti-dumping Subpart E, we cannot find any mention of previously manufactured materials. However, Subsection 80.102 "Controls applicable to blendstocks" does define "gasoline blendstocks" as products that are produced by a refiner but it also goes on to include other blendstocks with properties certain.
The condensate described herein would not meet the definitional requirements of a gasoline blendstock as its end point would disqualify it as a gasoline (if an oxygenate was added). The fractionator would separate the condensate into a gasoline component and a diesel component.
Is it the intention of the EPA that only manufactured products be used in blending either reformulated or conventional gasoline? Is it the intent to restrict the use of naturally occurring hydrocarbons in a fractionator that produces gasoline?See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The regulations do not prohibit or restrict the use or distribution of any gasoline or gasoline blendstocks regardless of their origin. Compliance with the anti-dumping requirements is based primarily on the properties of finished conventional gasoline. However, for…
