The RIA method for aromatics and olefins doesn't result in agreement with finished gasoline, i.e., the sum of the blendstock parameters doesn't equal the finished gasoline value (>6% delta). Are alternative methods okay?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Alternative test methods may be considered, based on the individual situation as explained in an alternate test method petition.

Is anti-dumping compliance the only restriction on conventional gasoline? Are there any future emissions reductions for conventional gasoline?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. All gasoline requirements currently in place, except for those applicable to reformulated gasoline, apply to conventional gasoline (e.g., volatility requirements, lead requirements, state oxygenated fuel requirements, etc.). The anti-dumping requirements are in addition to these. It is possible that…

A refinery has streams (alkylate, butane, platformate, etc.) being blended into two tanks, 95 and 85 octane. Products from these two tanks are in-line blended at the rack to give 87, 89, and 92 octane product. Can just the 85 and 95 octane tanks be certif
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Conventional gasoline that has been included in a refiner's compliance calculations may be fungibly mixed, including multi-grade mixing, without the need for additional sampling and testing.

For a refinery with an in-line gasoline blending exemption, can the annual in-line blending audit be conducted by the same attestation auditor as outlined under Subpart F of the RFG and Anti-dumping regulations? Must the auditor for an in-line blending op
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. An in-line blending exemption exempts a refiner from the independent sampling and testing requirements of § 80.65(f). As one of the conditions of the exemption, the refiner must carry out an independent audit program of its in-line blending operation…

On the registration forms it seems you are forced to check only one primary activity (refiner, oxygenate blender, importer, or independent lab). Do you submit two forms if you are both a refiner and importer?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. No. The final forms have been changed to register each company once for all applicable activities. As before, each facility will be registered separately for each activity that is undertaken at the facility. Import facilities need not be registered…

Regarding a batch for which the blend completion date is on the last day of the EPA reporting quarter, what if shipments, as EPA defines them, are not complete by the time reporting for that quarter is required? Is there going to be any facility to allow
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Sections 80.65(c) and 80.101(d)(1) require refiners to include in compliance calculations each batch of gasoline that is "produced." As a result, a batch of gasoline should be included in the averaging period when the batch is produced, rather than…

The regulations require a refiner or importer to determine and report properties for each batch of reformulated and conventional gasoline it produces or imports. The wording would indicate that a refiner would report the volume produced into a tank. A bet
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The method described above is appropriate for determining the volume and properties of a batch of conventional gasoline as required by the anti-dumping regulations provided the sample analyses and volume determination are supported by appropriate documentation.

The regulations require that an importer be registered 90 days before imports are received. Does this mean the company or the facility?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Both. If an importer chooses to register individual import facilities it must register them 90 days prior to shipping into them. However, an importer is only required to register its activities in each PADD (still 90 days in advance)…

With respect to section 80.65(a), would there be any violation by the terminal located in an RFG covered area selling only conventional gasoline to stations in attainment areas?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. No. However, the terminal should take extra precautions to ensure that no conventional gasoline is distributed to a RFG area. See the discussion in the Prohibitions and Liabilities Section.

Section 80.101(i) provides a composite sampling and testing option to determine conventional gasoline properties. One provision to this option is that composite samples will need to be prepared as described in § 80.91(d)(4)(iii). Part B of this procedure
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. The best process would be to avoid the butane adjustment by blending the fuels in such a way that butane loss is avoided. Practically, this means having all fuel samples at or below 32 degrees Fahrenheit before their containers…
