Table of Contents
Subpart A_General
Sec. 193.2007 Definitions.
As used in this part:
Administrator means the Administrator, Research and Special Programs
Administration or his or her delegate.
Ambient vaporizer means a vaporizer which derives heat from
naturally occurring heat sources, such as the atmosphere, sea water,
surface waters, or geothermal waters.
Cargo transfer system means a component, or system of components
functioning as a unit, used exclusively for transferring hazardous
fluids in bulk between a tank car, tank truck, or marine vessel and a
storage tank.
Component means 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 means a component other than piping that contains a
hazardous fluid.
[[Page 126]]
Control system means 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 means an emergency where reasonable and
prudent action can prevent harm to people or property.
Design pressure means 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 means 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 means the perimeter of an impounding space forming a barrier to
prevent liquid from flowing in an unintended direction.
Emergency means a deviation from normal operation, a structural
failure, or severe environmental conditions that probably would cause
harm to people or property.
Exclusion zone means an area surrounding an LNG facility in which an
operator or government agency legally controls all activities in
accordance with Sec. 193.2057 and Sec. 193.2059 for as long as the
facility is in operation.
Fail-safe means 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 means the standard acceleration of gravity of 9.806 meters per
second\2\ (32.17 feet per second\2\).
Gas, except when designated as inert, means natural gas, other
flammable gas, or gas which is toxic or corrosive.
Hazardous fluid means gas or hazardous liquid.
Hazardous liquid means LNG or a liquid that is flammable or toxic.
Heated vaporizer means a vaporizer which derives heat from other
than naturally occurring heat sources.
Impounding space means 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 means natural gas or synthetic gas
having methane (CH4) as its major constituent which has been
changed to a liquid.
LNG facility means a pipeline facility that is used for liquefying
natural gas or synthetic gas or transferring, storing, or vaporizing
liquefied natural gas.
LNG plant means an LNG facility or system of LNG facilities
functioning as a unit.
m\3\ means a volumetric unit which is one cubic metre, 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 means the maximum gage pressure
permissible at the top of the equipment, containers or pressure vessels
while operating at design temperature.
Normal operation means functioning within ranges of pressure,
temperature, flow, or other operating criteria required by this part.
Operator means a person who owns or operates an LNG facility.
Person means 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 means 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 means pipe, tubing, hoses, fittings, valves, pumps,
connections, safety devices or related components for containing the
flow of hazardous fluids.
Storage tank means a container for storing a hazardous fluid.
[[Page 127]]
Transfer piping means 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 means an addition of thermal energy changing a liquid
to a vapor or gaseous state.
Vaporizer means 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 means 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.
