U.S. regulators have given Venture Global VG.N permission to proceed with construction of its CP2 liquefied natural gas (LNG) plant in Louisiana, a FERC document showed on Friday.

If constructed, CP2 will be the single largest LNG export facility in the U.S. and help the country remain the world’s largest exporter of the superchilled gas. It also could make Venture Global the largest U.S. LNG company. 

The decision follows a final environmental study that shows the 28 million metric tons per annum plant is in the public interest.

Venture Global had obtained approval to construct the plant, but after a court ruling, FERC conducted an additional environmental review of the impact on air quality.
