A series of underground or aboveground valves controls transmission pipelines and most distribution mains. Only trained gas pipeline representatives or utility personnel 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 shutoff valves at meters or appliance supply lines. After a gas valve is closed, contact CPS Energy immediately. Only utility personnel may restore gas service.
