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…

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…

Section § 80.65(e)(2) contains a mechanism for identifying the test result a refiner or importer must use if the independent lab's test result does not corroborate the refiner's or importer's test result. Does this mechanism apply in a case where the independent lab's test result fails to corroborate the refiner's or importer's test result for a particular parameter, but where both test results are within the applicable maximum level for that parameter?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The mechanisms specified in § 80.65(e)(2)(ii), for instances where a refiner's or importer's RFG test result is not corroborated by the independent lab's test result, apply whenever there is such a non-corroboration. There is no exception in a…

The regulations state that, "other than when gasoline is sold or dispensed for use in motor vehicles at a retail outlet or wholesale purchaser-consumer facility," transfer documents must be exchanged with the requisite information. In many areas of the country, the petroleum industry is using cardlocks, unmanned fueling facilities, to dispense gasoline into motor vehicles. These cardlocks provide access to fleet operators via an electronic card, which is also used to access the pumps. The pumps transmit an electronic message regarding the purchase and the customer is invoiced. There is no opportunity for the delivery of written paper at the time of purchase. In EPA's judgment, are these cardlock facilities considered retail outlets?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . As you describe them, these cardlock facilities would be considered retail outlets for purposes of the product transfer document requirements. (10/31/94) This question and answer was posted at

Could a refinery producing conventional gasoline composite samples up to one month, ship to another location and run testing there?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Yes. The regulations do not specify where or by whom the testing may be performed. The refiner or importer is ultimately responsible for sampling and testing each batch of conventional gasoline and reporting the results to EPA. Composite…

For a conventional gasoline refiner that has oxygenate added downstream of the refinery, what sampling frequency and test methods must be used?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . For a refiner of blending stock to include in its compliance calculations the oxygenate used in blending conventional gasoline where the downstream blending was conducted by a person other than the refiner, § 80.101(d)(4)(ii)(B)(2) requires (among other things)…

Confirm that the attester will designate what is required to turn over a tank from one service to another, and how the barrels should be counted; i.e., from RBOB to conventional, or 3.5 wt% RBOB to 2.7 wt% RBOB.
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The attester will not designate products for the party subject to the attestation engagement requirement. The function of the attestation engagement is to provide an independent analysis of the designations made by the regulated party. The designation of…
