MARIPOSA COUNTY AIR POLLUTION CONTROL DISTRICT

RULE 213 - STORAGE OF PETROLEUM PRODUCTS

    1. Except as provided in subdivision (2), no person shall install or maintain any stationary gasoline tank with a capacity of 250 gallons or more which is not equipped for loading through a permanent submerged fill pipe, unless such tank is a pressure tank, or is equipped with a vapor recovery system, or with a floating roof, or unless such tank is equipped with other apparatus of equal efficiency which has been approved by the Air Pollution Control Officer.

    2. Subdivision (1) shall not apply to any stationary tanks installed prior to December 31, 1970.

    3. Subdivision (1) shall not apply to any stationary tank which is used primarily for the fueling of implements of husbandry, as such vehicles are defined in Division 16 (commencing with Section 36000) of the Vehicle Code.

    4. For the purpose of this Rule, "gasoline" means any petroleum distillate having a Reid vapor pressure of four pounds or greater.

    5. For the purpose of this Rule, "submerged fill pipe" means any fill pipe which has its discharge opening entirely submerged when the liquid level is six inches above the bottom of the tank. "Submerged fill pipe",when applied to a tank which is loaded from the side, means any fill pipe which has its discharge opening entirely submerged when the liquid level is 18 inches above the bottom of the tank.

    6. A "pressure tank" is a tank which maintains working pressure sufficient at all times to prevent hydro- carbon vapor or gas loss to the atmosphere.

    7. A "vapor recovery system" consists of a vapor gathering system capable of collecting the hydrocarbon vapors and gases discharged and a vapor disposal system capable of processing such hydrocarbon vapors and gases so as to prevent their emission to the atmosphere, with all tank gauging and sampling devices gas-tight except when gauging or sampling is taking place.

    8. A "floating roof" consists of a pontoon-type or double-deck-type roof, resting on the surface of the liquid contents and equipped with a closure seal, or seals, to close the space between the roof edge and tank wall. This control equipment shall not be used if the gasoline or petroleum distillate has a vapor pressure of 11.0 pounds per square inch absolute or greater under actual storage conditions. All tank gauging and sampling devices shall be gas-tight except when gauging or sampling is taking place.
  1. A person shall not place, store or hold in any stationary tank, reservoir or other container of more than 40,000 gallons capacity, any gasoline or any petroleum distillate having a vapor pressure of 1.5 pounds per square inch absolute or greater under actual storage conditions, unless such tank, reservoir or other container is a pressure tank, or equipped with a vapor recovery system, or a floating roof as described in subsection (A) of this Rule, or other equipment of equal efficiency, provided such equipment is approved by the Air Pollution Control Officer
