               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 below. For specific information regarding
borders, please consult your respective EPA regional office.

Summary of 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 40 CFR 80.27(d) have 1.0 psi waiver of applicable
   RVP standard unless:
   1) the State has adopted and enforces a SIP-approved RVP standard which does not provide for the
   1.0 psi waiver (e.g. Maine, New York, Pennsylvania, Texas);
   2) 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]; or
   3) the State uses reformulated gasoline (RFG), which has a more stringent VOC performance
   standard. Additional information about RFG can be found at www.epa.gov/otaq/rfg.htm.
  Alaska, Hawaii, and U.S. territories are exempted from federal volatility regulations.

                  Notes to Federal and State RVP Standards

State has received a waiver under Clean Air Act 21 l(c)(4)(C) to adopt a state fuel program, more
stringent than federal requirements, into the federally-approved State Implementation Plan (SIP).
State fuel program may also define a volatility level and compliance date for refiners and/or
terminals different than the compliance date for retailers. Potentially affected parties should
refer to the SIP or contact the State for more information about proper compliance.

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.

GA - 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.

Madison, Monroe, and St. Clair counties are RFG covered areas; however, a SIP requirement of
7.2 psi RVP is still in place.

State fuel program in federally-approved SIP does not provide for use of a 1.0 psi ethanol waiver
under 40 CFR 80.27(d).  The 1.0 psi ethanol waiver is not applicable during the entire volatility
control period defined  in the SIP (e.g. May 1 - September 15).

TX - 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, Hopkins, Houston, Hunt, Jackson, Jasper, Johnson, Karnes, Kaufman, Lamar,
Lavaca, Lee, Leon, Limestone, Live Oak, Madison, Marion, Matagorda, McLennan, Milam,
Morris, Nacogdoches,  Navarro, Newton, Nueces, Panola, Parker, Polk, Rains, Red River,
Refugio,  Robertson, Rockwall, Rusk, Sabine, San Jacinto, San Patricio,  San Augustine, Shelby,
Smith, Somervell, Titus,  Travis, Trinity, Tyler, Upshur, Van Zandt, Victoria, Walker,
Washington, Wharton, Williamson, Wilson, Wise, and Wood.
