2. a. Reid vapor pressure at 100°F, pounds per square inch
(psi)
Test Method ASTM D4953 or D5191 for both oxygenated or
nonoxygenated fuels.
Throughout the Commonwealth of Virginia, except for the
nonattainment areas specified below during the period specified below, the Reid
vapor pressure standard shall be:
|
|
|
|
|
|
|
|
|
|
|
|
For the nonattainment areas specified in Section 3 A 2 (ii)
below, the Reid vapor pressure standard shall be:
|
|
|
|
|
|
b. The nonattainment areas referred to in subsection A 2 a of
this section are:
(1) The Northern Virginia nonattainment area which includes
the counties of Arlington, Fairfax, Loudoun, Prince William, Stafford, and
includes the cities of Alexandria, Fairfax, Falls Church, Manassas, and
Manassas Park.
(2) The Richmond nonattainment area which includes the
counties of Charles City, Chesterfield, Hanover, Henrico, and includes the
cities of Colonial Heights, Hopewell, and Richmond.
(3) The Hampton Roads nonattainment area which includes the
counties of James City, York, and includes the cities of Chesapeake, Hampton,
Newport News, Norfolk, Poquoson, Portsmouth, Suffolk, Virginia Beach, and
Williamsburg.
The Reid vapor pressure values specified in subdivision A 2
of this section shall be increased one psi for gasoline-ethanol blends
containing at least 9.0% but not more than 10% ethanol by volume.
c. Throughout the Commonwealth of Virginia, from May 1 to
May 31 of each year, gasoline refiners, gasoline importers, gasoline pipeline
operators, and gasoline terminal operators shall supply fuel with a maximum
Reid vapor pressure standard of 9.0 psi.

ASTM D 4814-07b, "Standard Specification for Automotive Spark Ignition Engine Fuel," except that volatility standards for unleaded gasoline blended with ethanol shall not be more restrictive than those adopted under the rules, regulations, and Clean Air Act waivers of the U.S. Environmental Protection Agency. Gasoline blended with ethanol at concentrations up to 10% by volume shall be blended under any of the following three options:
1. The base gasoline used in such blends shall meet the requirements of ASTM D 4814 and the ethanol shall meet the requirements of ASTM D 4806-07a, "Standard Specification for Denatured Fuel Ethanol for Blending with Gasolines for Use as Automotive Spark-Ignition Engine Fuel," with the following exceptions applicable to the gasoline-ethanol blend:
a. The distillation minimum temperature at the 50 volume percent evaporated point shall not be less than 66°C (150°F);
b. The vapor/liquid ratio specification is waived for gasoline-ethanol blends of up to 10% ethanol;
2. The blend shall meet the requirements of ASTM D 4814; or
3. The base gasoline used in such blends shall meet all the requirements of ASTM D 4814 except distillation, and the blend shall meet the distillation requirements of ASTM D 4814.
Undissolved water and sediment, percent by volume, maximum 0.01% as determined by Virginia Department of Agriculture and Consumer Services (VDACS) Method of Test. The calculation for the VDACS Method of Test is as follows:
Volume of water and/or sediment ÷ total volume of sample x 100 = Percent Water and/or Sediment.
B. Blends of gasoline and ethanol shall meet the following vapor pressure requirements:
1. During the period between June 1 and September 15 of each calendar year, blends containing 9.0% ethanol by volume and a maximum of 10% ethanol by volume shall not exceed the ASTM D 4814 vapor pressure limits by more than 1.0 psi. All other blend concentrations shall meet the ASTM D 4814 vapor pressure limits.
2. During the period between September 16 and May 31 of each calendar year, all blends of gasoline and ethanol shall not exceed the ASTM D 4814 vapor pressure standard by more than 1.0 psi.
C. Diesel fuel. Diesel fuel shall meet the requirements of ASTM D 975-08, "Standard Specification for Diesel Fuel Oils."
