This legislative proposal, known as the LNG Export Security Act , aims to amend the Natural Gas Act by formally defining the term "public interest." This definition is intended to provide clear criteria for regulatory decisions concerning natural gas infrastructure and exports. The bill specifies that "public interest" must encompass the development of natural gas facilities within the United States and the expansion of the domestic natural gas supply . Additionally, it mandates the consideration of domestic economic interests and paramount national security interests when determining the public interest for natural gas projects.
