Cal. Code Regs. tit. 8 § 5566

Current through Register 2024 Notice Reg. No. 50, December 13, 2024
Section 5566 - Storage
(a) Liquids shall be stored in closed containers not exceeding 60 gallons capacity, in tanks in special enclosures as described in 5567, in aboveground tanks as provided for in (e), or in tanks located underground as in Sections 5597, 5598 and 5599. Vent pipes on tanks storing gasoline shall discharge only upward in order to disperse vapors. Also see Section 5578.
(b)
(1) Aboveground tanks, located at an adjoining bulk plant, may be connected by piping to service station underground tanks if, in addition to valves at aboveground tanks, a valve is also installed within control of service station personnel.
(2) Apparatus dispensing Category 1 or 2 flammable liquids, or Category 3 flammable liquids with a flashpoint below 100 °F (37.8 °C), into the fuel tanks of motor vehicles of the public shall not be located at a bulk plant unless separated by a fence or similar barrier from the area in which bulk operations are conducted.
(c) Category 1 or 2 flammable liquids, or Category 3 flammable liquids with a flashpoint below 100 °F (37.8 °C), shall not be stored or handled within a building having a basement or pit into which flammable vapors may travel, unless such area is provided with ventilation which will prevent the accumulation of flammable vapors therein.
(d) Tanks supplying marine service stations and pumps not integral with the dispensing unit shall be on shore or on a pier of the solid-fill type, except as provided in (1) and (2).
(1) Where a shore location would require excessively long supply lines to dispensers, tanks may be installed on piers provided that applicable portions of Article 145 relative to spacing, diking and piping are complied with and the quantity so stored does not exceed 1,100 gallons aggregate capacity.
(2) Shore tanks supplying marine service stations may be located aboveground where rock ledges or high water tables make underground tanks impractical.
(e) Where tanks are at an elevation which produces a gravity head on the dispensing unit, the tank outlet shall be equipped with a device, such as a solenoid valve, positioned adjacent to and downstream from the valve specified in Section 5596(b), so installed and adjusted that liquid cannot flow by gravity from the tank in case of piping or hose failure when the dispenser is not in use.
