DISTRIBUTION PIPELINE
A natural gas pipeline other than a gathering or transmission
line (reference 49 CFR 192.3). A distribution pipeline is generally
used to supply natural gas to the consumer and is found in a network
of piping located downstream of a natural gas transmission line.
GAS
Natural gas, flammable gas, or gas which is toxic or corrosive.
(Reference 49 CFR 192.3) Gases are normally compared to air in terms
of density. The specific gravity of air is 1.0. Any gas with a specific
gravity less than 1.0 (such as natural gas) will rise and usually
disperse. Any gas having a specific gravity greater than 1.0 will
fall and collect near the ground or in low-lying areas such as trenches,
vaults, ditches, and bell holes, such occurrences can be hazardous
to human health and safety.
GAS TRANSMISSION PIPELINE
A pipeline, other than a gathering line, that 1) transports
gas from a gathering line or storage facility to a distribution center,
storage facility, or large-volume customer that is not downstream
from a distribution center; 2) operates at a hoop stress of 20% or
more of specified minimum yield strength; or 3) transports gas within
a storage field. (Reference 49 CFR 192.3) A gas transmission pipeline
includes all parts of those physical facilities through which gas
moves in transportation, including pipe, valves, and other appurtenance
attached to pipe, compressor units, metering stations, regulator stations,
delivery stations, holders, and fabricated assemblies.
HAZARDOUS LIQUID
Includes petroleum, petroleum products, anhydrous ammonia,
and carbon dioxide. (Reference 49 CFR 195.2)
HAZARDOUS LIQUID PIPELINE
All parts of a pipeline facility through which a hazardous
liquids move in transportation, including, but not limited to, line
pipe, valves, and other appurtenances connected to line pipe, pumping
units, fabricated assemblies associated with pumping units, metering
and delivery stations and fabricated assemblies therein, and breakout
tanks.
INSTITUTIONAL USE
A nonprofit, religious, or public use, such as a religious
building, library; public or private school, hospital, or government-owned
or government-operated building, structure, or land used for public
purpose.
PETROLEUM PRODUCTS
Flammable, toxic, or corrosive products obtained from distilling
and processing of crude oil, unfinished oils, natural gas liquids,
blend stocks and other miscellaneous hydrocarbon compounds.
PIPELINE
Used broadly, pipeline includes all parts of those physical
facilities through which gas, hazardous liquid, or carbon dioxide
moves in transportation.
PIPELINE COMPRESSOR STATION, METERING STATION or OPERATION/MAINTENANCE
FACILITIES
A facility at which a petroleum product passing through a pipeline is pressurized by a turbine, motor, or engine, the volume of flow is measured or permanent facilities are installed for pipeline operation/maintenance and which compress, decompress, process, heat, dehydrate, alter or transform the pipeline product. The facility may contain some type of liquid separator consisting of scrubbers and filters that capture any liquids or other undesirable particles from the pipeline. The definition also includes utility transfer stations which are owned, operated and maintained by the local natural gas utility and mark the point at which it assumes official control of the gas. The definition excludes pipeline valves, metering stations, pig launchers/receivers, and other components which are located within the pipeline right-of-way and do not compress, decompress, process, heat, alter or transform the pipeline product. (See §
180-118 for additional standards applicable to pipeline compressor stations, metering stations and operation/maintenance facilities.)
PIPELINE CORRIDOR
The linear area where a transmission pipeline or hazardous
liquid pipeline and associated facilities are located, including rights-of-way
and easements over and through public or private property.
TRANSMISSION PIPELINE
When not specified, includes both hazardous liquid and gas
transmission pipelines. Transmission pipelines carry oil, petroleum
products, natural gas, natural gas liquids, anhydrous ammonia and
carbon dioxide from producing regions of the country to markets.
