Concerning the OFID test method for oxygenates:a) The method has a program run of 20 minutes, but over half the eluting peaks on the table in the method come off after 20 minutes. For example, the last oxygenate present on the table elutes off at 38 38 minutes. Can one use other chromatographic conditions such as those conditions set in the ASTM draft method for OFID analysis to achieve shorter retention time and better analytical techniques?

In filing company and facility registrations, if a parent corporation has several subsidiary corporations it desires to register and report to EPA under one company ID number, would it be permissible to register all of the facilities operated by the subsidiaries under only one of the corporations even though for legal and tax purposes they are regarded as separate entities under the umbrella of the one parent corporation? Would it be necessary to obtain a registration number for the parent corporation or could one of the subsidiary corporations take responsibility for compliance for all of the facilities?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help In this situation the parent corporation should register for a company ID # and facilities operated by the subsidiary corporations should be registered as separate facilities but under the parent corporation's company ID #.

After a batch of gasoline is certified as RFG, it is given a batch number. How far "downstream" does the batch number follow the material? If a batch is commingled in a terminal with other compatible material belonging to a variety of terminalling customers, does the batch lose its batch number at that time?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help There are no requirements to identify the batch number in the transfer documentation. Once the batch is commingled with other RFG, the refineries' batch numbers are no longer useful to identify the resulting fungible RFG. (10/17/94) This question and…

We believe that computer controlled sequential blending of oxygenates at the rack is at least as accurate as computer controlled in line blending. Is sequential blending of oxygenates at the rack considered sufficiently equivalent to computer in line blending to allow the sampling and testing rates under§ 80.69(a)(7)(i)(B) for in line blending?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help For purposes of § 80.69, computer controlled sequential blending is considered to be a form of computer controlled in line blending, and qualifies for the sampling and testing rates applicable to computer controlled oxygenate blending under §§ 80.69(a)(7)(i)(B)(2) and…

When a party lifts gasoline at a terminal, there is usually both a transfer of custody (to the carrier) and a transfer of title (to the person taking title). If all required PTD information is given to the carrier through a bill of lading, is it also necessary to provide a separate PTD to the person taking title? If so, does a single PTD suffice when the person taking title utilizes his own truck as opposed to common carrier trucks?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help . The transferor must provide PTD information to both the transferee of custody and the transferee of title. As a result, the required PTD information must be provided to both the carrier (the transferee of custody) and the person…
