Yesterday, the US Environmental Protection Agency (EPA) and the US Army Corps of Engineers (Corps) (together, the Agencies) published a final rule revising the definition of “waters of the United States” (WOTUS) subject to federal regulation and permitting requirements under the Clean Water Act (CWA).  This rule is the latest attempt by the Agencies to craft a durable rule defining WOTUS.  The new rule, which largely mirrors the 2021 proposal, asserts a broader geographic scope of federal jurisdiction than the 2020 Navigable Waters Protection Rule (NWPR).  In particular, the Agencies adopt the broadest possible interpretation of the Supreme Court’s decision in Rapanos (through incorporation of both the plurality’s “relatively permanent” test and Justice Kennedy’s “significant nexus” test).  The final rule would, for the first time, codify aspects of the Agencies’ 2008 Rapanos Guidance and would rely on the significant nexus test’s case-by-case approach for evaluating jurisdiction for tributaries, wetlands, and other waters.  The Agencies released the final rule while the Supreme Court considers the scope of CWA authority over a major category of WOTUS, “adjacent wetlands,” in Sackett v. EPA, and the Supreme Court could hand down a decision in the coming months that could require changes to the rule.Continue Reading EPA and Army Corps Issue New “WOTUS” Rule While Supreme Court Considers Jurisdiction Over Adjacent Wetlands

On December 27, 2021, the US Army Corps of Engineers (Corps) issued a final nationwide permit (NWP) rule renewing a critical permitting tool for both the government and the regulated community. To comply with the Clean Water Act (CWA or the Act), projects with minimal adverse environmental effects can obtain authorization for the discharge of dredged or fill material into “waters of the United States” (WOTUS) through the Corps’ streamlined NWP process. With this rule, the Corps reissued 40 existing NWPs and one new NWP. These 41 NWPs will combine with 16 NWPs issued on January 13, 2021 to authorize use of the full suite of NWPs through March 14, 2026.

Once large infrastructure projects, such as oil and natural gas pipelines, receive federal government approval, they are often the target of legal challenges from opposition groups. Opponents repeatedly argue that the environmental review, pursuant to the National Environmental Policy Act (NEPA), was insufficient. If a court finds deficiencies in the government’s NEPA analysis, can a court halt construction or cease operations even after years of project design, permit approvals at all levels of government, and tens of millions of dollars in investment? This question was at the heart of the ongoing litigation involving the controversial Dakota Access Pipeline (DAPL), and, on October 11, Judge James Boasberg determined “no,” the court would not shut down the pipeline. This case is important precedent for projects being challenged under NEPA.

Despite oil already flowing through the pipeline, federal litigation involving the controversial Dakota Access Pipeline (DAPL) took another turn last week when partial summary judgment was granted to tribes challenging the adequacy of the US Army Corps of Engineers’ review of DAPL under the National Environmental Policy Act (NEPA) and other statutes. Two tribes, the Standing Rock Sioux Tribe and the Cheyenne River Sioux Tribe, filed suit in July 2016 attempting to block construction of the last remaining segment and operation of DAPL. As sometimes is the case, agency approvals came faster than the court’s opinion, and without a stay of proceedings DAPL began operating in early June 2017. Having granted partial summary judgment, the court did not require pipeline operations to cease, instead delaying the question of an appropriate remedy until after further briefing by the parties.
