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.

Notes to Federal and State RVP Standards
State has received a waiver under Clean Air Act 21 l(c)(4)(C) to adopt a fuel program, more
stringent than federal requirements, into the federally-approved State Implementation Plan (SIP).
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" at
www.epa.gov/otaq/rfg/whereyoulive.htm. RFG areas must meet a VOC emissions performance
reduction standard per 40 CFR 80.41.
Madison, Monroe, and St. Clair counties will be RFG covered areas with an effective date for
retailers of July 1, 2007. However, the SIP requirement of 7.2 psi RVP is still in place until the
State of Illinois takes action to remove this provision from the SIP.
State fuel program in federally-approved SIP does not provide for use of a 1.0 psi ethanol waiver
under 80.27(d).
Atlanta area counties include: Banks, Barrow, Bartow, Butts, Carroll, Chattooga, Cherokee,
Clarke, Clayton, Cobb, Coweta, Dawson, DeKalb, Douglas, Fayette, Floyd, Forsyth, Fulton,
Gordon, Gwinnett, Hall, Haralson, Heard, Henry, Jackson, Jasper, Jones, Lamar, Lumpkin, Madison,
Meriwether, Monroe, Morgan, Newton, Oconee, Paulding, Pickens, Pike, Polk, Putnam, Rockdale,
Spalding, Troup, Upson, and Walton.
Eastern Texas Counties include: Anderson, Angelina, Aransas, Atascosa, Austin, Bastrop, Bee,
Bell, Bexar, Bosque, Bowie, Brazos, Burleson, Caldwell, Calhoun, Camp, Cass, Cherokee,
Colorado, Comal, Cooke, Coryell, De Witt, Delta, Ellis, Falls, Fannin, Fayette, Franklin, Freestone,
Goliad, Gonzales, Grayson, Gregg, Grimes, Guadalupe, Harrison, Hays, Henderson, Hill, Hood,

Wise, and Wood.
Federal Fuel Volatility Regulations at 40 CFR 80.27:
• For all regulated parties except retailers and wholesale purchaser-consumers, maximum standards
generally take effect May 1.
• Standards for June 1 to September 15 are maximum standards for all regulated parties including
retailers and wholesale purchaser-consumers, unless state has an extended summer season as part of
the federally-approved SIP (e.g. Arizona, Eastern Texas).
• Gasoline alcohol blends meeting requirements of 80.27(d) have 1.0 psi waiver of applicable RVP
standard unless the State has and enforces a SIP-approved RVP standard (e.g. Maine, Pennsylvania,
Texas) or the State has received EPA approval to opt-out of the 1.0 psi waiver provision per Section
1501(c) of the Energy Policy Act of 2005 [Clean Air Act 21 l(h)(5), as amended].
• Alaska, Hawaii, and U. S. territories are exempted from federal volatility regulations.
