Ariz. Admin. Code § R3-7-708 - Gasoline Oxygenate Blends
B.
Special provisions for gasoline ethanol
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.
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.
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.
