Safety is Our Focus – From Design to Delivery
At Columbia Gulf Transmission, we know that pipeline safety starts long before natural gas begins to flow. And we believe that our primary responsibility is to ensure public safety through responsible operations. We are committed to protecting the safety and well-being of our employees and the members of the communities in which we operate. Natural gas pipelines are subject to not only our own stringent internal controls but also must meet rigorous federal and state requirements and oversight.

Our operating facilities are kept under a constant watch 24 hours a day, seven days a week by the staff at our Gas Control monitoring centers. Team members working in these centers continuously gather and monitor data from pipelines and related facilities across our operating system and can control the flow of gas throughout our pipeline network.
