((18)) “pipeline facility” means a gas pipeline facility and a hazardous liquid pipeline facility;

((19)) “pipeline transportation” means transporting gas and transporting hazardous liquid;

((20)) “State” means a State of the United States, the District of Columbia, and Puerto Rico;

((21)) “transporting gas”—

((A)) means—

((i)) the gathering, transmission, or distribution of gas by pipeline, or the storage of gas, in interstate or foreign commerce; and

((ii)) the movement of gas through regulated gathering lines; but

((B)) does not include gathering gas (except through regulated gathering lines) in a rural area outside a populated area designated by the Secretary as a nonrural area;

((22)) “transporting hazardous liquid”—

((A)) means—

((i)) the movement of hazardous liquid by pipeline, or the storage of hazardous liquid incidental to the movement of hazardous liquid by pipeline, in or affecting interstate or foreign commerce; and

((ii)) the movement of hazardous liquid through regulated gathering lines; but

((B)) does not include moving hazardous liquid through—

((i)) gathering lines (except regulated gathering lines) in a rural area;

((ii)) onshore production, refining, or manufacturing facilities; or

((iii)) storage or in-plant piping systems associated with onshore production, refining, or manufacturing facilities;

((23)) “risk management” means the systematic application, by the owner or operator of a pipeline facility, of management policies, procedures, finite resources, and practices to the tasks of identifying, analyzing, assessing, reducing, and controlling risk in order to protect employees, the general public, the environment, and pipeline facilities;

((24)) “risk management plan” means a management plan utilized by a gas or hazardous liquid pipeline facility owner or operator that encompasses risk management;

((25)) “Secretary” means the Secretary of Transportation; and

((b)) ** .—**

((1))

((A)) Not later than , the Secretary shall prescribe standards defining the term “gathering line”.

((B)) In defining “gathering line” for gas, the Secretary—

((i)) shall consider functional and operational characteristics of the lines to be included in the definition; and

((ii)) is not bound by a classification the Commission establishes under the Natural Gas Act ( et seq.).

((2))

((A)) Not later than , the Secretary, if appropriate, shall prescribe standards defining the term “regulated gathering line”. In defining the term, the Secretary shall consider factors such as location, length of line from the well site, operating pressure, throughput, and the composition of the transported gas or hazardous liquid, as appropriate, in deciding on the types of lines that functionally are gathering but should be regulated under this chapter because of specific physical characteristics.

((B))

((i)) The Secretary also shall consider diameter when defining “regulated gathering line” for hazardous liquid.

((ii)) The definition of “regulated gathering line” for hazardous liquid may not include a crude oil gathering line that has a nominal diameter of not more than 6 inches, is operated at low pressure, and is located in a rural area that is not unusually sensitive to environmental damage.
