April 13 (LNGJ) - Williams Partners, majority owner of the largest-volume US interstate natural gas pipeline system Transco, is seeking regulatory approval for its Southeastern Trail Expansion Project to serve growing demand by 2020 in the Mid-Atlantic and Southeast regions of the nation. “Once complete, the project will help meet the growing natural gas demand in the Southeast, as well as provide access to new sources of domestic natural gas supply,” said the company. The project will continue expansion of southbound capacity on the Transco pipeline system. “Construction of this project along Transco’s existing corridor results in significantly less environmental impact and more economical transportation rates for our customers than other greenfield projects serving these same markets,” added Williams.
