As such, pipelines must ensure that the quality of the gasoline is not changed and provide product transfer documents. In order to establish…

We are a domestic refiner who also will be importing (paying customs duties) conventional and reformulated gasoline into our own marketing terminal. It is our understanding that we would be the transferor, not the foreign refiner from whom the product was obtained. If we were importing into another party's terminal, the PTD would have to show them as receiving the product (transferee).
EPA reiterated they expect that most, if not all, of the PTD information would be included on existing type documents. New documents would only be required when there is no existing paper path with the necessary EPA information to follow product movements. If the necessary PTD
information is included on the foreign refiner's transfer papers, is it necessary to originate another
document since we are the first U.S. party involved in the transfer.See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The foreign refiner's paperwork would satisfy the PTD requirements if you provide it to the transferee and it includes all of the required PTD information, including the proper date and location of the transfer.

In § 80.69(a)(2), the procedure for sampling and analysis of RBOB is defined. A hand blend with the specified type and amount of oxygenate is to be prepared and the blended sample analyzed, with those results to be used in compliance calculations. In §80.67(g), compliance totals are defined as the sum of each batch's volume times its parameters. What volume is to be used for RBOB in computing the compliance total -- the actual RBOB volume produced or the implicit volume after blending with the specified oxygenate volume and type?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The volume after blending with the specified oxygenate volume and type (i.e., the RBOB volume plus oxygenate) should be used for computing the compliance total. (11/28/94) This question and answer was posted at

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?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Under § 80.2(r), an importer is defined as "a person who imports gasoline or gasoline blending stocks or components from a foreign country into the United States...." Accordingly, it is the importer of the gasoline, and not the owner…

Section 80.80(e)(2) generally provides that a refiner or importer that fails to meet the independent analysis requirements of § 80.65(f) may not use the results of sampling and testing carried out by the regulated party as evidence of the properties of gasoline giving rise to a violation. Does this provision apply to California gasoline, which is exempt from the independent testing requirements?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. No. Because § 80.81(b)(2) exempts California gasoline from the § 80.65(f) independent analysis requirements, the "penalty" set forth in § 80.80(e)(2) for failure to meet these requirements is not applicable to such gasoline, unless this exemption is lost under…
