Component—any part, or system of parts functioning as a unit, including, but not limited to, piping, processing equipment, containers, control devices, impounding systems, lighting, security devices, fire control equipment, and communication equipment, whose integrity or reliability is necessary to maintain safety in controlling, processing, or containing a hazardous fluid.#

Container—a component other than piping that contains a hazardous fluid.#

Control System—a component, or system of components functioning as a unit, including control valves and sensing, warning, relief, shutdown, and other control devices, which is activated either manually or automatically to establish or maintain the performance of another component.#

Controllable Emergency—an emergency where reasonable and prudent action can prevent harm to people or property.#

Design Pressure—the pressure used in the design of components for the purpose of determining the minimum permissible thickness or physical characteristics of its various parts. When applicable, static head shall be included in the design pressure to determine the thickness of any specific part.#

Determine—make an appropriate investigation using scientific methods, reach a decision based on sound engineering judgment, and be able to demonstrate the basis of the decision.#

Dike—the perimeter of an impounding space forming a barrier to prevent liquid from flowing in an unintended direction.#

Emergency—a deviation from normal operation, a structural failure, or severe environmental conditions that probably would cause harm to people or property.#

Exclusion Zone—an area surrounding an LNG facility in which an operator or government agency legally controls all activities in accordance with LAC 43:XIII.6957 and LAC 43:XIII.6959 for as long as the facility is in operation.#

Fail-Safe—a design feature which will maintain or result in a safe condition in the event of malfunction or failure of a power supply, component, or control device.#

g—the standard acceleration of gravity of 9.806 meters per second2 (32.17 feet per second2).#

Gas—except when designated as inert, means natural gas, other flammable gas, or gas which is toxic or corrosive.#

Hazardous Fluid—gas or hazardous liquid.#

Hazardous Liquid—LNG or a liquid that is flammable or toxic.#

Heated Vaporizer—a vaporizer which derives heat from other than naturally occurring heat sources.#

Impounding Space—a volume of space formed by dikes and floors which is designed to confine a spill of hazardous liquid.#

Impounding System—includes an impounding space, including dikes and floors for conducting the flow of spilled hazardous liquids to an impounding space.#

Liquefied Natural Gas or LNG—natural gas or synthetic gas having methane (CH4) as its major constituent which has been changed to a liquid.#

LNG Facility—a pipeline facility that is used for liquefying natural gas or synthetic gas or transferring, storing, or vaporizing liquefied natural gas.#

LNG Plant—an LNG facility or system of LNG facilities functioning as a unit.#

m3—a volumetric unit which is one cubic meter, 6.2898 barrels, 35.3147 ft.3, or 264.1720 U.S. gallons, each volume being considered as equal to the other.#

Maximum Allowable Working Pressure—the maximum gage pressure permissible at the top of the equipment, containers or pressure vessels while operating at design temperature.#

Normal Operation—functioning within ranges of pressure, temperature, flow, or other operating criteria required by this part.#

Operator—a person who owns or operates an LNG facility.#

Person—any individual, firm, joint venture, partnership, corporation, association, state, municipality, cooperative association, or joint stock association and includes any trustee, receiver, assignee, or personal representative thereof.#

Pipeline Facility—new and existing piping, rights-of-way, and any equipment, facility, or building used in the transportation of gas or in the treatment of gas during the course of transportation.#

Piping—pipe, tubing, hoses, fittings, valves, pumps, connections, safety devices or related components for containing the flow of hazardous fluids.#

Storage Tank—a container for storing a hazardous fluid.#

Transfer Piping—a system of permanent and temporary piping used for transferring hazardous fluids between any of the following: Liquefaction process facilities, storage tanks, vaporizers, compressors, cargo transfer systems, and facilities other than pipeline facilities.#

Transfer System—includes transfer piping and cargo transfer system.#

Vaporization—an addition of thermal energy changing a liquid to a vapor or gaseous state.#

Vaporizer—a heat transfer facility designed to introduce thermal energy in a controlled manner for changing a liquid to a vapor or gaseous state.#

Waterfront LNG Plant—an LNG plant with docks, wharves, piers, or other structures in, on, or immediately adjacent to the navigable waters of the United States or Puerto Rico and any shore area immediately adjacent to those waters to which vessels may be secured and at which LNG cargo operations may be conducted.#
