Pipeline Transportation of Natural Gas
NAICS 486210 · United States · 2022 edition
This industry comprises establishments primarily engaged in the pipeline transportation of natural gas from processing plants to local distribution systems. This industry includes the storage of natural gas because the storage is usually done by the pipeline establishment and because a pipeline is inherently a network in which all the nodes are interdependent.
Start the review with explosion and fire.
For Pipeline Transportation of Natural Gas, the saved research highlights explosion and fire, environmental liability, control of well / blowout. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What is the total mileage of pipeline operated, and what operating pressures are typical?
- Are there compressor stations, metering facilities, or underground storage fields included in the operation?
- What is the age and inspection history of the pipeline infrastructure, including cathodic protection status?
- Has the operator had any PHMSA enforcement actions, consent decrees, or reportable incidents in recent years?
- Does the pipeline route pass through any high-consequence areas such as populated zones or near drinking water sources?
- For Pipeline Transportation of Natural Gas, what should the underwriter know about pipeline segments with deferred maintenance, aging infrastructure, or limited cathodic protection documentation?
- For Pipeline Transportation of Natural Gas, what should the underwriter know about prior phmsa enforcement actions, consent orders, or significant compliance violations?
- For Pipeline Transportation of Natural Gas, what should the underwriter know about operations routing through high-consequence areas (hcas) such as densely populated zones, drinking water sources, or environmentally sensitive areas?

Natural gas pipeline transportation establishments move natural gas under pressure through transmission pipelines from processing facilities to local distribution systems, often operating compressor stations, metering and regulation facilities, and underground storage fields along the way. Operations are largely automated and remotely monitored but require field technicians for inspection, maintenance, and emergency response. The pipeline network is inherently interdependent — a failure at one node can affect the entire system.
