(A) The location of a tank for the storage of any flammable liquid with respect to any such other tank shall be such that the distance between them shall be not less than three feet.
(B) For banks above 50,000 gallons individual capacity storing any flammable liquid, except crude petroleum in producing areas, the distance shall be not less than one-half the diameter of the smaller tank.
(C) In producing areas, for tanks storing crude petroleum and having capacities not exceeding 126,000 gallons (3,000 bbls.), the distance between tanks shall not be less than three feet; in excess of 126,000 gallons (3,000 bbls.), the distance shall be not less than the diameter of the smaller tank.
(D) The minimum separation between an LP gas container and a flammable liquid tank shall be 20 feet. Suitable means shall be taken to prevent the accumulation of flammable liquids under adjacent LP gas containers such as by diking, diversion curbs and grading. When flammable liquid tanks are diked, the LP gas containers shall be outside the diked area and at least 10 feet away from the centerline of the dike. The provisions set forth in this section shall not apply when LP gas containers of 125 gallons or less capacity are installed adjacent to Class III-B flammable liquid tanks of 275 gallons or less capacity.
