Calhoun LNG will consist of berthing facilities, storage tanks, vaporization and separation, utilities ad interconnecting pipelines. The berthing facilities can handle a variety of LNG tankers. The unloading dock will be equipped with three 16-foot diameter articulated LNG unloading arms and one 16-inch diameter vapor return arm.

The two storage tanks are capable of storing 160,000 cubic meters (5.7 million cubic feet) of LNG.

The vaporization and separation system consists of LNG transfer pumps, vaporizers and a re-condenser/separation system. The facility will be designed to separate natural gas liquids from the LNG, thus allowing the terminal to take higher Btu LNG.

Calhoun LNG will tie into existing port utilities such as power, water, wastewater and fire protection systems.

A pipeline connecting to the Calhoun LNG terminal will deliver natural gas to major pipelines in the region. The pipeline is a 27-mile, 36-inch pipeline designed to transport one billion cubic feet per day of natural gas from the LNG terminal. It will connect with nine major pipelines including five interstate and four intrastate pipeline systems.

In April 2009, the U.S. Coast Guard issued a letter of recommendation in support of the project. The letter expressed the Coast Guard's conclusion that waterways near the terminal site could handle vessel traffic near the proposed facilities.

The Federal Energy Regulatory Commission (FERC), which must give its approval before construction can begin, had not done so as of August 3, 2010.
