Secondary containment for oil-filled operation equipment under SPCC
On December 26, 2006, EPA provided an optional alternative to the general secondary containment requirements in 40 CFR §112.7(c) for qualified oil-filled operational equipment ( 71 FR 77266 ). Because the alternative is optional, an owner or operator could choose to comply with the existing SPCC requirements to provide general…

Section 80.106 states (a) "On each occasion when any person transfers custody or title to any conventional gasoline, the transferor shall provide to the transferee documents which include the following information: ...(1) through (7); (8) The requirements of this paragraph (a) apply to product that becomes gasoline upon the addition of oxygenate only." 80.65(d)(1) "All gasoline produced or imported shall be properly designated as either reformulated or conventional gasoline, or as RBOB." It would appear that 80.106 is referring to a conventional gasoline blendstock for oxygenate blending (CBOB?) which heretofore has not been defined or discussed. Are 80.106(a)(1) - (7) intended for all conventional and conventional oxygenated gasolines? If so, 241 the CBOB should be so identified to prevent confusion with regular conventional gasoline. Like RBOB, it should also contain the oxygenate information included in 80.77(i)(2) and (3).
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The regulations require that conventional blendstock which will become conventional gasoline solely upon the addition of oxygenate must be considered conventional gasoline for the purpose of complying with the anti-dumping requirements, including the transfer document provisions of §…

The regulations state that gasolines with RVP equal to or less than the RVP required under 40 CFR 80.27 (Summer Gasoline) shall use the applicable Summer Complex Model under 80.45 and the Winter Model for RVP's greater than that required under 40 CFR 80.27. In most areas of the country 9.0 psi was the summer specification under 40 CFR 80.27. Would this mean that any conventional gasoline produced to an RVP less than or equal to 9.0 psi would use the Summer Complex Model and greater than 9.0 psi would use the Winter Complex Model no matter what time of the year that gasoline is produced? Does the fact that under § 80.27 gasoline in the Southern Areas that goes to an ozone non-attainment area must be 7.8 psi alter this split in any way? Is 9.0 psi gasoline produced in California for distribution to Arizona certified with the Summer or Winter Complex Model?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Section 80.101(g)(5) and (6) state that the emissions performance of gasoline with an RVP that is equal to or less than that required under § 80.27 must be determined using the appropriate summer complex model and that the…

Now that the track is rebuilt, what else needs to be done and how long will it take?
There is still a lot of work to do. Contaminated soil to the north and south of the tracks need to be removed. A full site assessment, including extensive sampling, of areas and properties near the derailment site needs to be conducted. A full assessment of impacted creeks will be…

In determining E200 and E300, will EPA allow D-86 distillation point averaging of gasoline grade data which is ± 20°F before graphing?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . E200 and E300 values should be calculated separately for each batch of gasoline. If error bars are associated with distillation data for repeat tests on a given batch, the results may be averaged for the purposes of graphing…

The custody transfer point of the RBOB between the terminal operator and the exchange company is normally at the loading arm connection to the transport. Since the title to the RBOB is therefore held by the exchange company and not the terminal operator at the moment the RBOB enters the blending facility (the transport truck), is the terminal operator still considered an oxygenate blender in this situation? Our interpretation is that, in the case of automated sequential blending, the terminal would be an oxygenate blender because it "controls and supervises" the blending process. Likewise, it is our interpretation that the terminal operator would not be an oxygenate blender in a splash blending situation since the operator does not have 137 title to the RBOB or ethanol at the time of blending and does not supervise or control the blending process. Is this interpretation correct?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . Your interpretation is correct in the first situation. If, in the second situation, the transport truck operator controls the amounts of products to be splash blended in the truck, your interpretation is also correct. (7/1/94) This question and…

Currently, the EPA's GC/MS method for aromatics does not work (poor repeatability precision on successive sample injections.) Should refiners spend $100,000 each for GC/MS instruments before the EPA method development work is complete? What is the likelihood of the EPA later rejecting the GC/MS method altogether?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . When EPA developed the GC/MS method for the determination of aromatics in gasoline, samples that were run side by side after the method was completed showed that the precision of GC/MS was considerably better than D-1319. This study…

Are independent labs required to submit quality parameter data or the % reduction performance results to EPA?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The regulations require parameter comparisons and not emissions performance reduction comparisons. See § 80.65(f)(3)(iii)(B)(1). (11/10/97) This question and answer was posted at

Are distributors who deliver conventional gasoline to retailers and wholesale purchaser-consumers in non-RFG areas required to fulfill the PTD requirements, including the statement in § 80.106(a)(1)(vii)? Do retailers and wholesale purchaser-consumers in non-RFG areas have to retain records?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The PTD requirements of § 80.106 apply to all distributors of conventional gasoline. However, because the PTD requirements are of little value concerning the delivery of conventional gasoline to a retailer or wholesale purchaser-consumer (or smaller purchaser with…
