b'IAntprpoednudcitxio AnPipeline IntegrityThe industry uses a wide range of tools and technologies to maintain safe operations. In-line inspection tools known as smart pigs, hydrostatic test-ing, electro-magnetic testing, and other techniques are employed to identify defects that could threaten pipeline integrity. They visually inspect aboveg-round pipes and related equipment for corrosion and damage. Operator personnel walk, drive and fly over pipeline rights-of-way inspecting them for unauthorized activities, leaks, and other conditions that might endanger the pipeline or the public. Pipeline control center personnel continuously monitor pipeline operations and will initiate corrective actions if any prob-lems are identified.Emergencies Affecting PipelinesManytypesofemergencysituationscanaffectburiedpipelines.These include train derailments, floods, earthquakes, wildland fires, structure col-lapses, and other similar events where earth has been disturbed or will be moved as part of the response efforts. In these situations, pipeline compa-nies should be notified as soon as possible so they can monitor and verify the integrity of nearby pipelines.

If the call center procedures allow these types of notifications, all operators with buried facilities in the area will be notified and will respond.

They are now required in new and replaced service lines that supply gas to single-family residences. For larger commercial and industrial users, gas distribution companies are required to install curb valves, manually operated shutoff valves near the service main, or Excess Flow Valves in all new or replaced service lines with meter capaci-ties exceeding 1,000 standard cubic feet per hour. Policiesregardingtheoperationofcurbvalvesbyresponsepersonnel should be coordinated with local gas companies so all parties have a clear understanding about what might be expected in an emergency.31 2022 by Pipeline Association for Public Awareness'
