(24) "Service lateral" means an underground water, stormwater, or sewer facility located in a public right-of-way or utility easement that connects an end user's building or property to a facility operator's underground facility, and terminates beyond the public right-of-way or utility easement.
(25) "Transfer pipeline" means a buried or aboveground pipeline used to carry hazardous liquid between a tank vessel or transmission pipeline and the first valve inside secondary containment at a facility, provided that any discharge on the facility side of the first valve will not directly impact waters of the state. "Transfer pipeline" includes valves and other appurtenances connected to the pipeline, pumping units, and fabricated assemblies associated with pumping units. "Transfer pipeline" does not include process pipelines, pipelines carrying ballast or bilge water, transmission pipelines, or tank vessel or storage tanks.
(26) "Transmission pipeline" means a pipeline that transports hazardous liquid or gas within a storage field, or transports hazardous liquid or gas from an interstate pipeline or storage facility to a distribution main or a large volume hazardous liquid or gas user, or operates at a hoop stress of twenty percent or more of the specified minimum yield strength.
(27) "Underground facility" means any item buried or placed below ground for use in connection with the storage or conveyance of water, sewage, electronic, telephonic or telegraphic communications, cablevision, electric energy, petroleum products, gas, gaseous vapors, hazardous liquids, or other substances and including but not limited to pipes, sewers, conduits, cables, valves, lines, wires, manholes, attachments, and those parts of poles or anchors that are below ground.
