Pipeline valves

A series of underground or aboveground shutoff valves controls transmission pipelines and most distribution mains. Only trained emergency representatives of BHE GT&S, the local gas pipeline operator or the local gas utility should operate these valves. Never attempt to open or close underground or aboveground pipeline valves. Doing so could cause dangerous pressure changes or outages in the system.

If necessary, first responders may close aboveground service meter shutoff valves or appliance supply line shutoff valves. After a gas valve is closed, only trained gas pipeline representatives or utility personnel may reopen it.
