A lawsuit filed by environmental groups to challenge EPA’s new definition of “waters of the United States” (WOTUS) raised issues related to climate change. The complaint asserted that the final rule’s “typical year” requirement—which the rule uses to define when tributaries, lakes, ponds, and impoundments are jurisdictional waters—would “skew towards historical conditions that may no longer accurately represent today’s climate.”
