Over the past several decades, significant tension has developed between the federal role in overseeing and authorizing certain types of energy infrastructure projects and states’ roles in regulating water quality under the cooperative federalism structure of the Clean Water Act (CWA or the Act). This tension has played itself out in various contexts, but the most pronounced in recent years has been the battle over CWA Section 401 water quality certifications for energy infrastructure projects,…
Last week the Federal Energy Regulatory Commission (FERC) made some headway in how it evaluates greenhouse gas (GHG) emissions from natural gas-related projects. In recent FERC pipeline certification proceedings, the two Democrats on the Commission have been critical of how FERC addresses a project’s potential GHG emissions and climate change impacts.

On October 1, at oral argument before the U.S. Court of Appeals for the D.C. Circuit, the parties addressed…
The US Court of Appeals for the Third Circuit recently issued two decisions concerning the relationship between the Natural Gas Act (NGA) exclusive jurisdiction provision at 15 U.S.C. § 717r(d)(1) and the administrative review process for state-issued environmental permits for interstate natural gas pipeline projects. These decisions are briefly described as follows: In Delaware Riverkeeper et al. v. Sec PA Dept. Env. Protection, et al. (Sept. 4, 2018), the court held that only “final”…
