blends.
1. A gasoline ethanol blend that
meets the requirements in subsections (B)(1)(a) and (b) shall not exceed the
vapor pressure specified in ASTM D4814 by more than 1 psi:
a. The concentration of the
ethanol, excluding the required denaturing agent, shall be:
i. From May 1 through September
15, at least nine percent and no more than 10 percent by volume of the gasoline
ethanol blend; and
ii. From September 16 through
April 30, at least 1.5 percent by weight and no more than 10 percent by volume
of the gasoline ethanol blend; and
b. The ethanol content of the
gasoline ethanol blend shall:
i. Be determined using the
appropriate test method listed in ASTM D4814, and
ii. Not exceed any applicable
waiver condition under Section 211(f) of the Clean Air Act.
2. The provision in subsection
(B)(1) is effective for gasoline ethanol blends sold:
a. Outside the CBG-covered area
year around, and
b. Within the CBG-covered area
during April.
3. Gasoline blended with no more
than 10 percent by volume of fuel ethanol shall be blended using one of the
following alternatives:
a. The base gasoline complies with
the standards in ASTM D4814, the fuel ethanol complies with the standards in
ASTM D4806, and the finished blend complies with the standards in ASTM D4814
with the following permissible exceptions:
i. The distillation minimum
temperature at the 50 volume percent evaporated point is not less than 66°C
(150°F), and
ii. The minimum test temperature
at which the vapor/liquid ratio is equal to 20 is waived;
b. The finished blend complies
with the standards in ASTM D4814; or
c. The base gasoline complies with
the standards in ASTM D4814 except distillation and the finished blend complies
with the standards in ASTM D4814 with the following permissible
exceptions:
i. The distillation minimum
temperature at the 50 volume percent evaporated point is not less than 66°C
(150°F), and
ii. The minimum test temperature
at which the vapor/liquid ratio is equal to 20 is waived.
4. A gasoline ethanol blend shall
meet the standards specified in ASTM D4814.
B. Fuel ethanol specifications. A
person that
uses
fuel ethanol as a blending component with
conventional gasoline,
conventional gasoline blendstocks,
ethanol flex fuel,
AZRBOB, or
Arizona CBG
shall ensure that the
fuel ethanol meets the following requirements:
1. A sulfur content not exceeding 10 ppm by
weight;
2. The fuel ethanol must be
composed solely of carbon, hydrogen, nitrogen, oxygen, and sulfur;
3. Only
gasoline previously certified under
40 CFR Part
1090, Subpart C, (including previously certified blendstocks for
oxygenate blending),
gasoline blendstocks, natural gas liquids, or certified
ethanol denaturant that meets the requirements in
40 CFR §
1090.275 may be used as denaturants;
and
4. The concentration of all
denaturants is limited to a maximum of 3.0 volume percent.
C.
In addition to complying with the requirements in
R3-7-707, the transferor of an
oxygenated gasoline blend shall ensure that the product transfer document
contains a legible and conspicuous statement that the gasoline being
transferred contains an oxygenate and lists the type and percentage
concentration of the oxygenate.
C. For oxygenates other than
ethanol, the
oxygenate shall meet the applicable ASTM standard for the
oxygenate, and the
finished blend shall meet ASTM D4814.
D.
Nothing in this subsection shall preclude the sale
of gasoline with an ethanol content greater than 10 percent by volume and less
than or equal to 15 percent by volume of ethanol outside of the CBG-covered
area.
D. Special
provisions for
gasoline-
ethanol blends.
1.
Gasoline-ethanol blends shall meet ASTM D4814, except as provided in subsection
(D)(2) or (D)(3).
2. The maximum
vapor pressure for
gasoline blended with
fuel ethanol may exceed the
vapor
pressure requirements outlined in ASTM D4814 by no more than 1.0 psi (referred
to as the 1.0 psi waiver) for the following
gasoline-
ethanol blends:
a. Outside of the CBG-covered area if the
concentration of ethanol, excluding the required denaturing agent, is at least
9% by volume and no more than the maximum concentration of ethanol that is
allowed for the 1.0 psi waiver to apply under federal law;
b. In area B from October 1 through March 31
if the concentration of ethanol, excluding the required denaturing agent, is at
least 6% by volume and no more than 15% by volume.
c. Inside the CBG-covered area during April
only.
3. Gasoline blended
with no more than 15% by volume of
ethanol shall be blended using one of the
following alternatives:
a. The base
gasoline
complies with the standards in ASTM D4814, the
fuel ethanol complies with the
standards in ASTM D4806, and the finished blend complies with the standards in
ASTM D4814 with the following permissible exceptions:
i. The distillation minimum temperature at
the 50 volume percent evaporated point is not less than 66°C (150°F),
and
ii. The minimum test temperature
at which the vapor/liquid ratio is equal to 20 is waived;
or
b. The finished blend
complies with the standards in ASTM D4814.
E. Ethanol flex fuel sold or offered for sale
within the
CBG-covered area shall:
1. Use
fuel ethanol that meets the standards in this Chapter, and
2. Have a maximum
vapor pressure that does
not exceed the maximum
vapor pressure requirements in
R3-7-751(A)(6).
F. E15
sold or offered for sale within the
CBG-covered area shall:
1. Use fuel ethanol that meets the standards
in this Chapter, and
2. Be blended
with ethanol flex fuel that meets the requirements of subsection (E),
or
3. Be blended with Arizona CBG
