7 CCR 1101-14-1.5-4 - Product Quality

(a) All liquid fuel products in Classes I, II, and III shall comply with the applicable specifications of ASTM, which are found in the Annual Book of ASTM Standards Section 5 "Petroleum Products, Lubricants, and Fossil Fuels".

[Note 1: Class I flammable liquids include all grades of Gasoline, and most motor fuels blended using alcohol and MTBE (methyl-tertiary-butyl-ether).]

[Note 2: Class II combustible liquids include #1 and #2 Diesel Fuels, #1 and #2 Heating Oil, Kerosene, and Jet-A grade Jet fuel.]

[Note 3: Class III combustible liquids include most lubricating oils and heavy fuel oils.]

(b) If gasoline is blended with ethanol, the ASTM D 4814 specifications shall apply to the base gasoline prior to blending. Blends of gasoline and ethanol shall not exceed the ASTM D 4814 vapor pressure standard, except that, if the ethanol is blended at nine percent or higher but not exceeding ten percent, the blend may exceed the ASTM D 4814 vapor pressure standard by no more than 1.0 PSI.

(c) In addition to the above, all liquid fuel products shall comply with the requirements published in the NIST Handbook 130 "Uniform Laws and Regulations in the area of legal metrology and engine fuel quality" except as modified or rejected by this regulation.

(d) The allowable reductions in vehicle antiknock requirements for altitude are 4.5 for less than 89 Antiknock Index (AKI), and 3.0 for greater than 89 AKI. Fuel may be marketed using these reductions, but actual AKI minimum must be posted.
