  • Section 80.46(a) was amended by the rule to require the use of ASTM D-3246 to determine the sulfur content of butane. Many refiners and butane suppliers do not currently use that method. Requiring a new method prior to the 2004 effective date of the gasol

  • A refiner produces a batch of gasoline at its refinery. It collects a sample of the gasoline and conducts certification testing. The sulfur content test result is less than the 80 ppm refinery level standard. The gasoline is then moved to another tank wit

Reformulated Gasoline & Anti-Dumping

  • A refinery has two product tanks in series; a 10,000 gallon tank in which blendstocks are combined to produce gasoline (a blend tank), followed by a 50,000 gallon tank which feeds directly to the rack. Customers pull product from the rack. There are no bl

  • Refiners or importers producing or importing RBOB must blend the proper amount of oxygen with the RBOB and test it for the regulated parameters pursuant to § 80.69(a)(2). Since they are not responsible for the oxygen content, must they test for oxygen, an

  • Regarding the requirement in § 80.69(a)(2) that refiners and importers blend a representative sample of an RBOB batch with refinery-specified oxygenate, the composition of specified oxygenate blended in the laboratory is likely to differ from the composit

Registration

  • If an importer is unsure of what terminals might be involved in importing gasoline (RFG or conventional), may importers register more terminals than might be used?

  • In a situation where an importer leases tankage from another company, e.g., from a for-hire terminal, who must register such import facility, the company that owns the terminal, the importer that leases the tankage, or both?

  • 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?

  • Will common carriers be required to register their transport trucks as oxygenate blending facilities?
