FERC proposed to revise its blanket certificate regulations for interstate natural gas pipelines. Section 7 of the Natural Gas Act, 15 U.S.C. 717f, provides that no natural gas company may engage in the transportation and sale of natural gas in interstate commerce for resale, the construction of facilities to be used in those activities, or the abandonment of any jurisdictional service or facilities, without first obtaining prior Commission approval for such activities. To fulfill this statutory responsibility, FERC has implemented a number of different certificate programs, including various generic determinations of public convenience and necessity. In proposing to revise its generic determinations, FERC stated that it aims to “significantly broaden…the types and sizes of projects that interstate natural gas pipelines can build without case-by-case approval, dramatically expanding the scope and scale of infrastructure covered under the Commission’s natural gas blanket program.” Ease of construction absent the need for project-specific approval would likely expand natural gas production and corresponding GHG emissions.
