"Maximum allowable operating pressure (MAOP)" means the maximum pressure at which a pipeline may be operated under this chapter.
"Municipality" means a city, county, or any other political subdivision of a state.

"Pipeline facility" means new and existing pipelines, 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.
"Service line" means a distribution line that transports gas from a common source of supply to
(1) A customer meter or the connection to a customer's piping, whichever is farther downstream; or
(2) The connection to a customer's piping if there is no customer meter. A customer meter is the meter that measures the transfer of gas from an operator to a consumer.
"SMYS" means specified minimum yield strength is:
(1) For steel pipe manufactured in accordance with an unknown or unlisted specification, the yield strength determined in accordance with section 6-77-30(b);
(2) For steel pipe manufactured in accordance with an unknown or unlisted specification, the yield strength determined in accordance with section 6-77-30(b).
"State" means the State of Hawaii.
"Transmission line" means a pipeline, other than a gathering line, that:
(1) Transports gas from a gathering line or storage facility to a distribution center or storage facility;
(2) Operates at a hoop stress of twenty percent or more SMYS; or
(3) Transports gas within a storage field.
"Transportation of gas" means the gathering, transmission, or distribution of gas by pipeline or the storage of gas, in or affecting interstate or foreign commerce.
