CO Code § 8-20-232.5 (2021)
2021 Colorado Code|Title 8 - Labor and Industry|Article 20 - Fuel Products|Part 2 - Fuel Products|§ 8-20-232.5. Method of Sales of Motor Fuels - Gallon Equivalents - Conversion Factors

  In addition to any other allowed unit of measurement, motor fuels may be sold by gallon equivalents pursuant to the requirements of this section.      Any dispenser used for the sale of motor fuel in gallon equivalents shall display gallon equivalents as the primary display information provided. Such dispenser shall indicate the number of gallon equivalents and fractions of gallon equivalents sold, the total sales price of the motor fuel dispensed, and the sales price per gallon equivalent of motor fuel sold. Information concerning the sale of motor fuels by gallon equivalents may be provided at the point of sale in literature, signs, or other advertisements. Street sign advertisements regarding the sale of motor fuels by gallon equivalents may abbreviate the term “gallon gasoline equivalent” as “gallon G.E.” and the term “gallon diesel equivalent” as “gallon D.E.”.    In addition to the information required by paragraph (a) of this subsection (2), the face of a dispenser that is used for the sale of motor fuel in gallon equivalents shall prominently display the conversion factor that is being used by the seller to determine the number of gallon equivalents sold based upon the type and amount of actual measured units of motor fuel that is dispensed. The information displayed on such a dispenser shall include, but is not limited to, the following statements concerning the conversion factor:   “One gallon diesel equivalent of (type of motor fuel) is equivalent to (amount of actual units of measurement) of (type of motor fuel).”    “One gallon diesel equivalent of (type of motor fuel) contains an average lower heating value of 128,000 BTUs of energy, but in no case contains a lower heating value of less than 124,000 BTUs of energy.”    “One gallon gasoline equivalent of (type of motor fuel) is equivalent to (amount of actual units of measurement) of (type of motor fuel).”    “One gallon gasoline equivalent of (type of motor fuel) contains an average lower heating value of 114,000 BTUs of energy, but in no case contains a lower heating value of less than 110,000 BTUs of energy.”          Any seller using gallon equivalents for motor fuel sales shall calculate the conversion factor used by the seller to convert the actual units by which a motor fuel is measured at the dispenser to gallon equivalent units based on the inferred energy content of such motor fuel as measured by one of the following methods:   For conversions to gallon diesel equivalents:   If the motor fuel is actually measured at the dispenser as a volume, the gallon diesel equivalent measurement shall be calculated by determining the number of measured volumetric units required to provide an average lower heating value of one hundred twenty-eight thousand BTUs (British thermal units), but in no case a lower heating value of less than one hundred twenty-four thousand BTUs.    If the motor fuel is actually measured at the dispenser as a mass, the gallon diesel equivalent measurement shall be calculated by determining the number of measured mass units required to provide an average lower heating value of one hundred twenty-eight thousand BTUs (British thermal units), but in no case a lower heating value of less than one hundred twenty-four thousand BTUs.       For conversions to gallon gasoline equivalents:   If the motor fuel is actually measured at the dispenser as a volume, the gallon gasoline equivalent measurement shall be calculated by determining the number of measured volumetric units required to provide an average lower heating value of one hundred fourteen thousand BTUs (British thermal units), but in no case a lower heating value of less than one hundred ten thousand BTUs.    If the motor fuel is actually measured at the dispenser as a mass, the gallon gasoline equivalent measurement shall be calculated by determining the number of measured mass units required to provide an average lower heating value of one hundred fourteen thousand BTUs (British thermal units), but in no case a lower heating value of less than one hundred ten thousand BTUs.          The actual unit of measurement for a motor fuel sold in terms of gallon equivalents shall be calibrated by the seller with appropriate precision to ensure conformance with any required dispensing accuracies.
