In 2022, the on-going debate will continue over the hotly contested definition of “waters of the United States” (WOTUS), a phrase that determines the scope of federal jurisdiction over streams, wetlands and other waterbodies under the Clean Water Act (CWA). The WOTUS definition is included in 11 federal regulations and affects, among others, NPDES and Section 404 permitting, SPCC plans and spill reporting. This year, both the executive and judicial branches of the federal government are expected to weigh in on this definition, without any guarantee that their interpretations will be consistent.
Proposed Rule 1
USEPA and the Corps have already taken the first step to revise the WOTUS definition, as promised by President Biden during his campaign, by publishing a proposed rulemaking on December 7, 2021 (Rule 1). While this proposed definition is similar to the pre-2015 definition of WOTUS, which is currently in effect, it also reflects relevant Supreme Court decisions (e.g., Rapanos v. United States) that occurred in the early 2000s.
Much of the controversy surrounding the WOTUS definition relates to the two tests identified in the Rapanos decision. Justice Antonin Scalia issued the plurality opinion in Rapanos, holding that WOTUS would include only “relatively permanent, standing or continuously flowing bodies of water” connected to traditional navigable waters, and to “wetlands with a continuous surface connection to such relatively permanent waters.” Justice Anthony Kennedy, however, advanced a broader interpretation of WOTUS in his concurring opinion, which was based on the concept of a “significant nexus,” meaning that wetlands should be considered as WOTUS “if the wetlands, either alone or in combination with similarly situated lands in the region, significantly affect the chemical, physical, and biological integrity of other covered water.”
If promulgated, the December 2021 proposed WOTUS definition would incorporate Justice Kennedy’s significant nexus test into the regulations. …
