Port Dolphin LNG Permit Documents

U.S. EPA Region 4 is the agency responsible for issuing Clean Air Act (CAA) permits to liquefied natural gas (LNG) deepwater ports that may be located on the Outer Continental Shelf beyond the seaward boundaries of the States of Alabama, Florida, and Mississippi. These facilities, primarily vessels, will be engaged in vaporizing imported LNG and sending it to shore through pipelines and will be located a minimum of three miles, but often much farther, from shore. If licensed, such projects will require an air quality preconstruction permit and Title V operating permit issued pursuant to the CAA and applicable regulations.  Below is the Port Dolphin LNG Final Permit.  Other documents will be added as time allows at a later date.
