High Pressure Distribution System means a distribution system in which the gas pressure in the main is higher than the pressure provided to the customer. Imminent Hazard means the existence of a condition relating to a gas or hazardous liquid pipeline facility that presents a substantial likelihood that death, serious illness, severe personal injury, or a substantial endangerment to health, property, or the environment may occur before the reasonable foreseeable completion date of a formal proceeding begun to lessen the risk of such death, illness, injury, or endangerment. Incident means any of the following events: (1) An event that involves a release of gas from a pipeline, gas from an underground natural gas storage facility,, and that results in one or more of the following consequences: (i) A death, or personal injury necessitating in-patient hospitalization; (ii) Estimated property damage of $122,000 or more, including loss to the operator and others, or both, but excluding the cost of gas lost; For adjustments for inflation observed in calendar year 2021 onwards, changes to the reporting threshold will be posted on PHMSA's website. These changes will be determined in accordance with the procedures in Appendix A to part 191; or (iii) Unintentional estimated gas loss of three million cubic feet or more. (2) An event that is significant in the judgment of the operator, even though it did not meet the criteria of paragraph (1) or (2) of this definition. Key Valves means shut off valves in a distribution system or transmission line which may be necessary to isolate segments of a system or line for emergency purposes. Line Section means a continuous run of transmission line between adjacent compressor stations, between a compressor station and storage facilities, between a compressor station and a block valve, or between adjacent block valves. Listed Specification means a specification listed in Section I of Appendix B to Part 192. Low-Pressure Distribution System means a distribution system in which the gas pressure in the main is substantially the same as the pressure provided to the customer. Main means a distribution line that serves as a common source of supply for more than one service line. Master Meter System means a pipeline system for distributing gas within, but not limited to, a definable area, such as a mobile home park, housing project, or apartment complex, where the operator purchases metered gas from an outside source for resale through a gas distribution pipeline system. The gas distribution pipeline system supplies the ultimate consumer who either purchases the gas directly through a meter or by other means, such as the payment of rent. Maximum Actual Operating Pressure means the maximum pressure that occurs during normal operations over a period of one year. Maximum Allowable Operating Pressure (MAOP) means the maximum pressure at which a pipeline or segment of a pipeline may be operated under this code. Mobile Home Park means two or more mobile homes located on a contiguous tract of land. Municipality means a city, county or any other political subdivision of the State of Arkansas. Manual service line shut-off valve means a curb valve or other manually operated valve located near he service line that is safely accessible to operator personnel or other personnel authorized by the operator to manually shut off gas flow to the service line, if needed. Offshore means beyond the line of ordinary low water along that portion of the coast of the United States that is in direct contact with the open seas and beyond the line marking the seaward limit of inland waters. Operator means a person who: (1) Engages in the transportation of gas; or (2) Operates a distribution system within a mobile home park, public housing authority, or multiple building complex if: (A) The system: (i) Is not owned, nor the responsibility of a public or municipal utility; and (ii) Is used to transport gas from a master meter or a public/municipal utility main to consumers who may or may not be metered; and (B) The gas distributed is not consumed solely by the owner/operator. Person means an 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. Petroleum Gas means propane, propylene, butane (normal butane or isobutanes), and butylene (including isomers), or mixtures composed predominantly of these gases, having a vapor pressure not exceeding 208 p.s.i.g. (1434 kPa) gage at 100°F (38°C). Petroleum Refinery means an industrial or manufacturing facility or plant primarily engaged in producing gasoline, kerosene, distillate fuel oils, residual fuel oils, lubricants or other products through the processing of petroleum crude oil that is subject to: (A) The federal Environmental Protection Agency Standards of Performance for New Stationary Sources set forth in Subpart GGG of 40 CFR Part 60 or successor regulations; (B) The federal Environmental Protection Agency Chemical Accident Prevention Provisions set forth in Subparts, A, B, D, E, F, G, and H of 40 CFR Part 68 or successor regulations; and (C) The federal Occupational Safety and Health Administration Regulations governing process safety management of highly hazardous chemicals set forth in 29 CFR §1910.119 or successor regulations.

Production Process means the extraction of gas from the geological source of supply to the surface of the earth, thence through the lines and equipment used to treat, compress and measure the gas between the wellhead and the meter where it is either sold or delivered to a custodian other than the well operator for gathering and transport to a place of sale, sometimes called a "custodial transfer meter." Service Line means a distribution line that transports gas from a common source of supply to an individual customer, to two adjacent or adjoining residential or small commercial customers, or to multiple residential or small commercial customers served through a meter header or manifold. A service line ends at the outlet of the customer meter or at the connection to a customer's piping, whichever is further downstream, or at the connection to customer piping if there is no meter.
