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.

Eleventh Circuit Confirms Proper Scope of NEPA Review Governing Corps Clean Water Act Section 404 Permit
On November 4, 2019, the US Court of Appeals for the Eleventh Circuit upheld the Clean Water Act (CWA) section 404 permit issued by the US Army Corps of Engineers (Corps) for the extension of an existing phosphate mine in central Florida. Center for Biological Diversity v. U.S. Army Corps of Engineers, No. 18-10541 (11th Cir. Nov. 4, 2019). The Corps permit authorizes the discharge of dredged or fill material into waters of the United States that comprise a small portion of the mining extension. Opponents challenged the permit in the Middle District of Florida, claiming the issuance of the permit violated the CWA, the National Environmental Policy Act (NEPA) by not considering “downstream” effects, and the Endangered Species Act (ESA). The district court rejected all of the claims, and the Eleventh Circuit affirmed.

Fifth Circuit Vacates Preliminary Injunction on Appeal, Allowing Bayou Bridge Pipeline to Proceed
The US District Court for the Middle District of Louisiana ordered the $750 million Bayou Bridge pipeline to halt construction within the Atchafalaya Basin when it concluded that the US Army Corps of Engineers’ environmental analysis likely violated the National Environmental Policy Act and the Clean Water Act due to the following deficiencies: the Corps did not provide sufficient explanation for how the proposed off-site mitigation would compensate for the loss of wetlands impacted by construction; and the Corps failed to sufficiently consider and address historical impacts to wetlands from past pipeline projects in the cumulative effects analysis. On appeal, however, the US Court of Appeals for the Fifth Circuit overturned the lower court. …
