The INGAA Foundation, Inc. prepared an analysis of the process by which natural gas pipeline and storage facilities are approved to provide service in interstate commerce in the United States. The study presents a review of the evolution of the process from the Natural Gas Act of 1938 through the present. The review examines the relative merits of the current market-based process for reviewing and approving new interstate natural gas infrastructure vs. the historic processes utilized prior to the competitive restructuring of the natural gas industry, as well as to possible changes such that the current policy is replaced by one that is predicated on a regional planning model.
