May RFG that is found to be off-spec downstream of the refinery or import facility be corrected by blending "clean" non-oxygenate blendstocks?

See More Frequent Questions about Fuels Registration, Reporting, and Compliance Help.

Any party who combines blendstocks other than oxygenate with RFG is producing gasoline, and must meet all the RFG standards and requirements applicable to a refiner. In addition, all applicable RFG standards must be met by the blendstock only. The blendstock, therefore, in effect must be RFG, and such blending is the equivalent of blending RFG with RFG.

A party who does not meet the RFG refiner standards and requirements can take remedial action for RFG that violates applicable standards using the methods discussed above in Question 1. (7/1/94)
