Be it enacted by the General Assembly of the State of South Carolina:

Aboveground storage, handling, and use of flammable and combustible liquids

SECTION 1. Section 39-41-260 of the 1976 Code, as added by Act 76 of 1989, is amended to read:

"Section 39-41-260. (A) The storage, handling, and use of flammable and combustible liquids shall comply with the applicable provisions of the National Fire Protection Association Pamphlet No. 30, 1987 Edition, and all referenced publications in this pamphlet and the National Fire Protection Association Pamphlet No. 30A, 1987 Edition, and all referenced publications in this pamphlet except for the aboveground storage of flammable and combustible liquids at service stations as provided by this section.

(B) A maximum of thirty thousand gallons aggregate capacity of flammable or combustible liquids, or both, may be stored aboveground at service stations. No single storage tank shall exceed twelve thousand gallons liquid capacity. Service stations with an aboveground storage tank in excess of twelve thousand gallons liquid capacity on the effective date of this provision are exempt from this section.

(C) All aboveground storage tanks located at service stations must be enclosed by an eight-foot high industrial type chain link fenceNext with barbed wire barricade with a minimum of two means of emergency access located at opposite ends of the enclosure. Each access must be at least thirty-six inches wide and must be locked at all times except when entering or exiting. There must be a minimum working distance of at least five feet between the tank and the PreviousfenceNext. The area inside the PreviousfenceNext and diked area must at all times be clear of trash, combustible storage, and vegetation. Existing service stations on the effective date of this provision with aboveground storage tanks that are enclosed with a PreviousfenceNext constructed as referenced above are allowed to continue operating with the existing working distance between the tanks and the Previousfence.

(D) All aboveground storage tanks located at service stations with thirty thousand gallons aggregate storage capacity must be located a minimum of fifty feet from the nearest occupied building on the property, a minimum of fifty feet from a dispenser, a minimum of fifty feet from the nearest side of a public way, and a minimum of one hundred feet from a property line which is or can be built upon including the opposite side of a public way. All aboveground storage tanks located at service stations with twelve thousand gallons aggregate storage capacity must be located a minimum of thirty-seven feet from the nearest occupied building on the property, a minimum of thirty-seven feet from a dispenser, a minimum of thirty-seven feet from the nearest side of a public way, and a minimum of forty feet from a property line which is or can be built upon including the opposite side of a public way. Service stations with twelve thousand gallons aggregate storage capacity shall not have a storage tank in excess of four thousand gallons liquid capacity.

(E) All service stations that have aboveground storage tanks that contain flammable or combustible liquids, or both, shall have a minimum of three hundred thousand dollars of public liability insurance.

(F) Scaled plans for the renovation or construction of a service station that utilizes aboveground storage of flammable or combustible liquids, or both, must be submitted to the State Fire Marshal or his designee by registered receipt mail for approval before beginning construction. The State Fire Marshal or his designee shall approve or deny the plans within sixty calendar days or they are automatically considered approved. The plans must contain the following information:

(1) site plan;

(2) spill containment plan;

(3) piping layout with valves and fitting details;

(4) normal and emergency ventilation design;

(5) tank capacity and design standard;

(6) electrical plan;

(7) tank and piping support details;

(8) on site fire protection equipment; and

(9) tank location with respect to other tanks and dike.

(G) All feeder lines from aboveground tanks to dispensers located at service stations must be located underground and covered with a minimum of three feet of earth cover or eighteen inches of well tamped earth cover plus six inches of reinforced concrete or eight inches of asphaltic concrete.

(H) Piping must be equipped with a fifty-two valve that cuts off the flow of liquid when the dispensing pump is not operating, as well as a quick shut-off device at the tank that will shut off the flow of product.

(I) All horizontal tanks located at service stations must be installed on steel supports welded to the tank not to exceed six inches in height or placed on concrete support cradles, and all vertical tanks must be installed on gravel with a minimum of six inches reinforced concrete footing. Footing is to be larger than the diameter of the tank.

(J) Two single portable tanks of six hundred sixty gallon capacity or less of Class II or Class III combustible liquid are allowed at service stations and are exempt from the requirements of this section.

(K) All aboveground tanks located at service stations must be clearly labeled with appropriate placards as to the contents of volume and kept free of scale and painted.

(L) A means must be provided to enable determination of liquid level in aboveground tanks located at service stations without requiring a person to climb atop the tank. Provisions must be made to either automatically shut off fuel delivery into the aboveground tank when the liquid level in the tank reaches ninety-five percent of capacity or to sound an audible alarm. This provision shall not apply to horizontal tanks of four thousand gallons or less and vertical tanks of two thousand gallons or less which must be filled with a hand held hose.

(M) Regardless of whether a suction or submersible pump system is used, a listed emergency shut-off valve must be installed in accordance with Section 4-3.6 of the National Fire Protection Association Pamphlet No. 30A, 1987 Edition, at each dispenser connected to an aboveground storage tank located at a service station.

(N) Fill connections located at service stations for tank vehicle unloading operations must be located at least twenty-five feet from aboveground tanks, dispensers, building, and property lines. A check valve, gate valve, and quick connector or a dry break valve must be installed in the piping at a point where connection and disconnection is made for remote tank vehicle unloading. The devices must be protected from tampering and physical damage. Means must be provided to prevent or contain spillage during fuel delivery operations. This provision shall not apply to horizontal tanks of four thousand gallons or less, and vertical tanks of two thousand gallons or less. Fill connections at existing service stations on the effective date of this provision are exempt from the distance requirement referenced above.

(O) Unattended service station installations in accordance with Section 8-5 of the National Fire Protection Association Pamphlet No. 30A, 1987 Edition, are permitted only when the dispensing device is a card lock or key lock type dispenser.

(P) Aboveground storage of flammable or combustible liquids at service stations is prohibited in municipalities with a population of twenty-five thousand persons or greater as determined by the most recent official United States Census, except as otherwise provided in subsection (J) of this section."
