Bridgeline Holdings crosses many bridges with natural gas and holds on to it, too. The company owns natural gas transportation and storage assets in southern Louisiana. Bridgeline Holdings buys, sells, and transports gas for industrial and utility customers through a more than 1,000-mile long natural gas pipeline system that runs from Texas to Louisiana. It also operates nearly 10 billion cu. ft. of capacity of salt dome storage. The company, now a wholly owned subsidiary of Chevron, was once 40% owned by Houston-based Targa Resources (formerly held by Enron).
