Guide on Federal and State Summer RVP Standards
for Conventional Gasoline Only
This guide is intended for quick reference purposes only. Federal volatility regulations (40 CFR 80.27) apply to
"designated volatility nonattainment areas" and to "designated volatility attainment areas," as defined in 40 CFR
80.2(cc) and 80.2(dd), respectively. For this quick reference guide, we have listed RVP limits by county,
which may not coincide precisely with the borders of a nonattainment or attainment area. We have not listed
RVP limits which may apply through voluntary agreements for supply of lower RVP fuel than what is otherwise
required for an area. For a brief description of the federal fuel volatility regulations, see the last page of this
guide. For specific information regarding borders, please consult your respective EPA regional office.

* * * Indicates there are counties or areas in counties in the state which have reformulated gasoline (RFG)
requirements. See EPA's "List of Federal Reformulated Gasoline Program Areas," January, 2002. RFG

Denver/Boulder: The applicable federal volatility standard from June 1 to September 15 is 7.8 psi.
