at liquefied natural gas (LNG) and liquefied petroleum gas (LP-GAS) facilities (Repealed)

(a) Liquefied natural gas (LNG) storage facilities. Liquefied natural gas (LNG) storage facilities shall have a protective enclosure for aboveground components and a security system with controlled access designed to minimize entry by unauthorized persons. The protective enclosure shall be illuminated and include a non-combustible peripheral fence, building walls or natural barriers and be a minimum of six feet in height, topped by a tamper-resistant system to discourage unlawful entry or trespass. The tamper-resistant system shall consist of at least three strands of barbed wire or other material sufficient to protect the facility. Peripheral fences, building walls, or natural barriers in excess of 10 feet in height shall not require a tamper-resistant material or system. The protective enclosure shall include major aboveground facility components, such as: (1) Liquefied natural gas containers; (2) outdoor aboveground process equipment areas, including fill station(s); and (3) on-shore loading and unloading equipment. (b) Liquefied Petroleum Gas (LP-GAS) Storage Facilities. (1) Liquefied Petroleum Gas (LP-GAS) Storage Facilities storing more than 4,000 gallons aggregate water capacity. Liquefied petroleum gas (LP-GAS) storage facilities storing more than 4,000 gallons aggregate water capacity shall have a protective enclosure for aboveground components and a security system with controlled access designed to minimize entry by unauthorized persons. The protective enclosure shall be illuminated if operated during the hours of darkness and include a non-combustible peripheral fence, building walls or natural barriers and be a minimum of six feet in height and topped by a tamper-resistant system to discourage unlawful entry or trespass. The tamper-resistant system shall consist of at least three strands of barbed wire or other material sufficient to protect the facility. Peripheral fences, building walls, or natural barriers in excess of 10 feet in height shall not require a tamper-resistant material or system. The protective enclosure shall include major aboveground facility components, such as: (A) Liquefied petroleum gas containers; (B) outdoor process equipment areas; and (C) on-shore loading and unloading equipment. (2) Liquefied petroleum gas (LP-GAS) storage facilities storing 4,000 gallons or less aggregate water capacity and facilities transferring liquid LP-Gas into a building piping system or another container of any size other than the motor vehicle fuel container. Liquefied petroleum gas (LP-GAS) storage facilities storing 4,000 gallons or less aggregate water capacity and facilities transferring liquid LP-Gas into a building piping system or another container of any size other than the motor vehicle fuel container shall be protected with an enclosure with controlled access, which shall be designed to minimize entry by unauthorized persons and intruders, including a non-combustible peripheral fence, building walls or natural barriers a minimum of six feet in height to promote security of the facility. The protective enclosure shall include major facility components, such as: (A) Liquefied petroleum gas aboveground containers; and (B) outdoor process equipment areas, including remote transfer points. (3) Liquefied petroleum gas (LP-GAS) storage facilities storing more than 2,000 gallons and up to and including 4,000 gallons aggregate water capacity aboveground and facilities where liquefied petroleum gas in the vapor phase is used to supply LP-GAS vapor at consumer sites, including but not limited to home(s) or residence(s), commercial or industrial buildings. Liquefied petroleum gas (LP-GAS) storage facilities storing more than 2,000 gallons and up to and including 4,000 gallons aggregate water capacity aboveground, and facilities where liquefied petroleum gas in the vapor phase is used to supply LP-GAS vapor at consumer sites, including but not limited to home(s) or residence(s), commercial or industrial buildings, shall be protected with an enclosure with controlled access, which shall be designed to minimize entry by unauthorized persons and intruders, and include a non-combustible peripheral fence, building walls, or natural barriers a minimum of six feet in height to promote security of the facility. The protective enclosure shall include major facility components such as: (A) Liquefied petroleum gas aboveground containers; and (B) outdoor process equipment areas, including remote transfer points. (4) Liquefied petroleum gas (LP-Gas) storage facilities storing containers 2,000 gallons aggregate water capacity or less. Liquefied petroleum gas (LP-Gas) storage facilities storing containers 2,000 gallons aggregate water capacity or less used to supply LP-GAS at consumer sites, including but not limited to a home or residence, commercial or industrial building, do not require protection with an enclosure. (c) The protective enclosures for liquefied natural gas (LNG) and liquefied petroleum gas (LP-GAS) storage facilities may be met by either one continuous enclosure or several independent enclosures. When the enclosed area exceeds 1,250 square feet, not less than two exit gates or doors located as remote as practical from each other shall be provided for rapid escape of personnel in the event of an emergency. (d) The presence of such protective enclosures shall not create significant hazards such as pocketing of liquefied natural gas (LNG) or liquefied petroleum gas (LP-GAS), interference with application of cooling water by fire departments, redirection of flames against containers and impeding egress of personnel in an emergency. (e) Lockable metal cabinets housing the dispensing controls for liquefied petroleum gas (LP-Gas) storage facilities do not require protection with an enclosure.
