On August 29, 2023, the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers issued a direct final rule that revised the “waters of the United States” (WOTUS) definition rule. This rule amended the final WOTUS rule, previously published in January 2023, to be consistent with the Supreme Court’s May decision in Sackett v. Environmental Protection Agency. On September 14, the Environmental Law Institute hosted a panel of experts to analyze the new rule and discuss its regulatory and policy consequences.

On May 25, 2023, the U.S. Supreme Court dropped an absolute bombshell with its ruling in Sackett v. Environmental Protection Agency. Early assessments of Sackett underscore two vital points: much has been lost for wetlands protection, and much has changed with respect to the Court’s broader environmental law jurisprudence. This Comment delves into both of these issues, providing some background on the unique and long-running controversy that was at the heart of Sackett, and parsing the four opinions from the case.

The U.S. Supreme Court’s May ruling in Sackett v. Environmental Protection Agency sharply limited the scope of the federal Clean Water Act’s (CWA’s) protection for the nation’s waters. The Court redefined the Act’s coverage of “waters of the United States” (WOTUS), effectively removing protection from many wetlands that have been covered under the Act for almost a half century. On June 8, 2023, the Environmental Law Institute hosted a panel of experts that analyzed the consequences of Sackett and discussed what actions can be taken to protect non-WOTUS waters.

October 18, 2022, marked the anniversary of the Clean Water Act (CWA), the primary federal law governing pollution control and quality of the waters of the United States. Though the Act has achieved vital successes, whether they can be sustained and how further progress can be made remain fundamental questions. On October 25, 2022, the Environmental Law Institute hosted a panel of experts at its 2022 Annual Policy Forum to evaluate the past 50 years of the CWA, while looking ahead to the next 50 years.
