"Emergency work" means nonroutine maintenance or repair work, such as repairs to hazardous leaks, that should be performed immediately. Examples include third party damages, repairs, work to maintain priority service, reduce customer outages as a matter of safety, and compromises to system integrity as a cause of overpressurization.
"Engineered structures" means distribution mains vertically attached to buildings, overpasses, or water crossings.
"Gate station" means pressure regulating stations where custody of natural gas or hazardous liquid is transferred from an interstate supplier to a Virginia public service company.
"Maintenance" means any repair or rehabilitation activity performed on a pipeline facility or prescribed by 49 CFR 192, Subpart M.
"MAOP" means maximum allowable operating pressure.
"O&M Procedures" means any operations or maintenance procedures or processes prepared by the operator for conducting operations and maintenance activities or emergency response, as prescribed by 49 CFR 192, Subpart L.
"Peak shaving facilities" means pipeline storage facilities designed to house natural gas or propane gas for reintroduction into an operator's system at times of peak demand. These facilities may store liquefied natural gas or liquefied petroleum gas.

"PSIG" means pounds per square inch, gauge.
"Repair" means any activity on a distribution main or transmission line that calls for removing the leak by cutting out and replacing a cylindrical piece of pipe, installing a pressure-carrying full encirclement welded split sleeve of appropriate design, or any other permanent repair that is consistent with 49 CFR § 192.717.
"Tie-in" means any process of connecting a newly installed pipeline to either an existing pipeline or another newly installed pipeline by means of joining.
