Frequent Questions

Do all properties have to be analyzed on-line to get an exemption from the independent laboratory sampling and testing requirement?

No. However, EPA would prefer that in-line blending operations at least be capable of analyzing benzene, oxygen, and RVP on line. If the operation does not have the capability to analyze all properties on-line, the refiner must indicate in his petition how he intends to determine the fuel properties for those parameters not analyzed on-line, and provide sufficient cross-checks of the results from a composite sample to warrant an exemption from the independent sampling and testing requirements. In-line blending petitions will be evaluated on a case-by-case basis with regard to the operation's capability to analyze all properties on-line.(7/1/94)
