OAR 340-232-0080: Bulk Gasoline Plants Including Transfer of Gasoline

(1) No person may transfer or allow the transfer of gasoline to or from a bulk gasoline plant unless: (a) Each stationary storage tank uses submerged fill when transferring gasoline; and (b) The displaced vapors from filling each tank are prevented from being released to the atmosphere through use of a vapor tight vapor balance system. All equipment associated with the vapor balance system must be maintained to be vapor tight and in good working order. (2) Each stationary gasoline storage tank may release vapor to the atmosphere through a pressure relief valve set to release at the highest possible pressure in accordance with state or local fire codes, or the National Fire Prevention Association guidelines and no less than 3.4 kPa (0.50 psi). (3) Gasoline must be handled in a manner to prevent spillage, discharging into sewers, storage in open containers, or handled in any other manner that would result in evaporation. If more than five gallons are spilled, the operator must report the spillage in accordance with OAR 340-214-0300 to 340-214-0350.
