A Clean Air Act air permit has been issued for the proposed Texas GulfLink (TGL) offshore deepwater port, clearing the way for first-of-its-kind vapor capture and control technology to be used at sea during crude oil loading operations.
Planned about 30 miles southeast of Freeport, Texas, the port will be capable of loading Very Large Crude Carriers (VLCCs) at a rate of up to 85,000 barrels per hour—equal to roughly 365 million barrels per year.
The permit sets requirements for monitoring, recordkeeping, and compliance reporting, and is valid for five years before renewal is needed. It combines both construction and operating conditions under the Clean Air Act.
Supporters say the project demonstrates how proven vapor-control technology can be applied offshore to reduce emissions while enabling significant growth in U.S. oil exports.
The approval follows a public comment period earlier this year. Under the Deepwater Port Act, the project also requires a separate license from the U.S. Maritime Administration before operations can begin.
