An oil export facility about 30 miles off the Texas coast has received its federal air quality permit.

On Sept. 14, the EPA issued a Clean Air Act permit for the Texas GulfLink deepwater port, a facility offshore from Freeport, Texas, that will be capable of loading “very large crude carriers,” one of the largest classes of oil tankers used in international shipping.

If built, GulfLink would have the capacity to export 1 million barrels per day and would be supplied by a nearly 33-mile pipeline. The pipeline would be part of 57 miles of new pipeline planned to connect GulfLink with the proposed Jones Creek Storage Terminal and Bryan Mound, an underground salt cavern storage site that is part of the Department of Energy’s Strategic Petroleum Reserve.
