Unlocking our Domestic LNG Potential Act of 2023 This bill repeals certain restrictions on the import and export of natural gas under the Natural Gas Act, including (1) a requirement that the Federal Energy Regulatory Commission (FERC) authorize an order to export or import natural gas only if it is in the public interest, and (2) restrictions related to free trade agreements. The bill also grants the FERC the exclusive authority to approve or deny applications for the siting, construction, expansion, or operation of facilities (e.g., liquefied natural gas terminals) to export natural gas to foreign countries or import natural gas from foreign countries.
