Section 02.02.14.350 - SALE AND LABELING OF GASOLINE WHICH CONTAINS OXYGENATES01.Pump Labeling Requirements. a. All spark ignition engine fuel kept, offered, or exposed for sale, or sold, at retail containing at least one percent (1%) by volume and not more than ten percent (10%) by volume of any oxygenate or combination of oxygenates must be identified as "with" or "containing" (or similar wording) the specific type of oxygenate(s) in the engine fuel. For example, the label may read "contains ethanol" or "with MTBE/ETBE." This information must be posted on the upper fifty percent (50%) of the dispenser front panel in a position clear and conspicuous from the driver's position, in a type at least one half (1/2) inch in height, one-sixteenth (1/16) inch stroke (width of type).b. The labels are to be furnished by the retail owner or operator.02.Oxygenates Content Labels. a. The label must have letters in bold face, block not less than one-half (1/2) inch high. The lettering must be in black on a contrasting background. Both colors must be non-fade.b. The label must be displayed on both faces of the dispenser on the upper one-half (1/2) of the dispenser as near the unit price display as practical.03.Documentation for Dispenser Labeling Purposes. The retailer must be provided, at the time of delivery of the fuel, on an invoice, bill of lading, shipping paper, or other documentation, a declaration of any oxygenate or combination of oxygenates present in concentrations of at least one percent (1%) by volume of the fuel. This documentation is only for dispenser labeling purposes; it is the responsibility of any potential blender to determine the total oxygen content of the engine fuel before blending.04.Fuel Specifications for Gasoline and Gasoline-Oxygenate Blends.a. The version of ASTM D 4814 "Standard Specification for Automotive Spark-Ignition Engine Fuel" incorporated by reference in this rule is the standard for gasoline and gasoline oxygenate blends, except the volatility standards for unleaded gasoline blended with ethanol must 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 must be blended under any of the following three (3) options. i. The base gasoline used in such blends must meet the requirements of ASTM D 4814, orii. The blend must meet the requirements of ASTM D 4814, oriii. The base gasoline used in such blends must meet all the requirements for gasoline of ASTM D 4814 except distillation, and the blend must meet the distillation requirements of the ASTM specification.b. Blends of gasoline and ethanol must not exceed the ASTM D 4814 vapor pressure standard by more than one point zero (1.0) psi.Idaho Admin. Code r. 02.02.14.350
