Repercussions of a Montana District Court’s vacatur of the U.S. Army Corps of Engineers (Corps) Nationwide Permit (NWP) 12 continue to unfold. NWP 12 is widely utilized by pipeline developers, other energy project proponents, and utilities to authorize certain stream and wetland crossings, and any resulting discharge of dredged or fill material into waters of the United States under Section 404 of the Clean Water Act (CWA).
NWP 12 was cast into a state of confusion in mid-April, when a federal judge in Montana, presiding over a challenge to the Keystone XL Pipeline, vacated the nationwide permit, asserting that the Corps failed to comply with the Endangered Species Act (ESA) when the NWPs were last issued in 2017. The court enjoined the Corps from authorizing any activities under the permit, pending completion of Corps consultations with the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, Services) regarding the permit’s impact on listed species or critical habitat. The order, issued in Northern Plains Resource Council, et al. v. Army Corps of Engineers, has resulted in an immediate halt to the review of thousands of pending NWP 12 requests and, unless stayed, is expected to result in lengthy delays and increased costs for companies engaged in the construction and maintenance of pipelines and other utility lines throughout the country.

The NWPs are published by the Corps approximately every five years, with the last publication in 2017, when 52 NWPs were issued. …
