Frequent Questions

A procedure has been outlined by the EPA for the certification of oxygen content by meter for the oxyfuel program. Can this method be used for certification of oxygen content in reformulated gasoline? Is an exemption for in-line blending required?

No. The regulatory method for oxygen testing, or the approved temporary method discussed in question 39, must be used for certification of reformulated gasoline produced at the refinery and also for blending oxygenate with RBOB. For further discussion of the exemption see the In-line Blending Section.(7/1/94)
