Key areas of focus include greenfield development options to connect our natural gas pipelines to northern gas reserves and emerging Canadian and U.S. shale gas supplies, and transporting crude oil from the Alberta oil sands.
Columbia is invested in a broad array of value-added pipeline infrastructure projects that support long-term system safety and reliability and will help meet American's growing need for energy.
