On May 18, 2018, the Federal Energy Regulatory Commission (FERC) issued an order denying a rehearing request on FERC’s prior issuance of a certificate of public convenience and necessity for a natural gas pipeline project for Dominion Transmission. An environmental group had challenged that certificate, arguing in part that FERC failed to adequately consider the upstream and downstream impacts of the project. These upstream and downstream impacts, according to the environmental group, included greenhouse gas (GHG) emissions. FERC, on a party-line vote, concluded that the upstream and downstream GHG impacts of this particular project were not sufficiently causally connected to and/or the reasonable foreseeable effect of the project and therefore fell outside of the scope of the required NEPA analysis. FERC distinguished its holding with the decision in Sierra Club v. FERC, 867 F.3d 1357 (D.C. Cir. 2017) by noting that in that case, the pipeline project was delivering natural gas to identifiable gas-fired electric generating plants and therefore the downstream use of the gas was foreseeable.

The Delaware Riverkeeper Network sent a letter to FERC asking it to formally rescind its May 18 order, claiming that FERC’s decision was contrary to the requirements of NEPA. This letter, along with similar letters from other environmental groups, are likely precursors to legal challenges to FERC’s interpretation of its obligations under NEPA. Notwithstanding the positions being advanced by these environmental groups, FERC continues to review and approve pipeline projects without requiring a detailed analysis of GHG emissions as evidenced by FERC’s May 31 approval of the Okeechobee Lateral Project.
