CWA Update: Two Recent Cases Impact CWA Permitting and Enforcement

Energy and Environmental Trends Watch

Two recent cases have the potential to dramatically alter the state of permitting and enforcement under the federal Clean Water Act (“CWA”) with far reaching implications to energy infrastructure project proponents and the regulated community. 

In the first case, Northern Plans Resource Council v. U.S. Army Corps of Engineers, No. 4:19-cv-00044-BMM (D. Mont), the Montana District Court last month vacated the U.S. Army Corps of Engineers Nationwide Permit 12 (“NWP 12”) for the Keystone XL Pipeline Project, concluding that the Corps failed to consult under the Endangered Species Act (“ESA”) Section 7 when it reissued NWP 12 in 2017. Although that case involved only the Keystone XL Pipeline Project, the Order enjoined the Corps from authorizing any work under NWP 12 until an ESA consultation is completed, effectively resulting in a nationwide injunction of work permitted under NWP 12. NWP 12 provides a streamlined CWA permitting process for thousands of linear “utility line activities” (i.e., pipelines and electrical or communication transmission lines) that would otherwise be forced to apply for numerous individual CWA permits to complete a single project. The nationwide vacatur of NWP 12 created significant uncertainty for project proponents who were left with three options: 1) apply for other potentially applicable nationwide permits, 2) apply for individual CWA Section 404 permits, or 3) redesign a project to avoid impacts to regulated waters.
