All aspects of the life cycle of a pipeline – from design and construction to operation and retirement – are guided by our comprehensive Operational Management System and strictly overseen by regulatory agencies and government departments. That's why every TC Energy pipeline is rigorously and precisely built with high-quality materials and the latest proven technology, and monitored by expert staff, every step of the way. Take the journey with us, and learn about the life cycle of a pipeline from planning to monitoring and beyond.

Extending from New York state to the Midwest and Southeast, TC Energy’s Columbia Gas Transmission system moves the natural gas relied upon by millions of Americans for their energy and heating needs.
