              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 (Reid Vapor Pressure) 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.
