Compare another operationInsurance operations research — draft
Natural gas distribution companies operate and maintain pipeline networks — including mains, service lines, meters, regulators, and related infrastructure — that deliver natural gas from transmission systems to residential, commercial, and industrial end users. Day-to-day operations typically include pipeline inspection and integrity management, leak surveys, meter reading and maintenance, excavation and line work by field crews, emergency response to gas leaks and outages, and customer service. Gas marketers and brokers in this classification may primarily perform commercial and financial transactions rather than operating physical infrastructure.
