On February 18, 2021, the U.S. Federal Energy Regulatory Commission (FERC) reopened the comment period for its Notice of Inquiry (NOI) on the Certification of New Interstate Natural Gas Facilities. FERC applies its current policy, issued in 1999, to assess whether to issue interstate natural gas transportation facilities a Certificate of Public Convenience and Necessity (CPCN), a foundational permit required for their construction and operation. FERC must abide with its obligations under the Natural Gas Act and National Environmental Policy Act when considering pipeline certificate applications. FERC initially issued the NOI in April 2018, seeking comment on whether, and if so how, it should revise its approach to evaluating CPCN applications. The docket has been pending for nearly three years.
