For conventional gasolines, the annual compliance report is based on all gasolines. Can one monthly composite be made up of all grades of gasolines and all seasons produced in that month, rather than one composite for each grade and season when compliance is demonstrated with the simple model? the complex?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. For the criteria for using composite samples for compliance calculations, see § 80.101(i)(2). (10/17/94) This question and answer was posted at

Confirm that an RFG property measured from a sample collected during an EPA inspection is in technical violation if that property exceeds an applicable standard, but that no enforcement action will be brought by EPA unless the property exceeded the standard in question by at least the enforcement tolerance for that property.
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. As stated in the preamble to the RFG final rule, at 59 FR 7764 (February 16, 1994), EPA will not initiate an enforcement action on the basis of a test result from a gasoline sample collected at a facility…

Confirm that the only specification for a blendstock being added to finished gasoline in early use of the Simple Model is a per gallon specification not exceeding the antidumping baseline exhaust benzene level, (per Section 80.101(g)(3)), and later the exhaust toxic and exhaust NOx baseline levels in 1998 and beyond. This is very important to clearly understand as regular CBOB is not a fungible grade of gasoline. Component blending with finished regular and ethanol is a very important option to blending regular CBOB with ethanol in terminals. This option is critical whenever the refinery that feeds the CBOB terminals requires maintenance or has operational problems, and no other refinery that feeds that terminal makes regular CBOB.
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. Under the simple model for 1995-1997, refiners and importers are required to meet standards for exhaust benzene, sulfur, olefins and T90 on an annual average basis for conventional gasoline and, under certain conditions, applicable blendstocks as specified in §…

For aromatics, it must also be correlated to the GC-MS method. Correlation to…

In a computer-controlled in-line blending operation, adjustments to blending volumes and other blending parameters are made on an ongoing basis to keep the gasoline being blended on-spec. Normally, these adjustments are made automatically by a computer. However, some aspects of the blending operation must be placed in a manual mode when instrument problems arise. The operator is able to enter values (transfer volumes, blend volumes) in the case of such a manual mode operation. The computer records when manually-entered adjustments are made. Is this acceptable data control to the EPA?
See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help. It would seem to be appropriate for the software to indicate when data are manually entered, who entered the data and when it was entered. This information should be recorded with the file for the batch and available for…
