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.

Using the most comprehensive data set on U.S. household recycling behavior, this Comment quantifies the relative impact on recycling of characteristics associated with recycling in different populations, under different governmental rules, and having different facilitating resources and amenities.

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.

A robust and growing commercial space sector is moving ahead at warp speed. While the industry today primarily offers satellite and launch services, tomorrow will bring manufacturing, research and development, resource extraction, and space tourism. What do these developments mean for the earth’s biosphere, as well as for the environments of other celestial bodies finally within humanity’s reach? This is the role of planetary protection, the principle of safeguarding both terrestrial and extraterrestrial environments from humanity’s propensity for introducing pollution into any habitat.

The Oak Ridge Reservation is one of the largest U.S. Department of Energy (DOE) facilities in the country, with areas that are highly contaminated by chemicals, metals, and radionuclides. DOE is in the middle of a multi-decade, multi-billion-dollar cleanup there, and a recent Superfund decision for one portion of the site raises a number of significant legal issues. This Article addresses some related questions: Should radionuclides get less stringent cleanup than other equally harmful pollutants like mercury and polychlorinated biphenyls?

Many chemicals and hazardous substances are kept in places that can withstand ordinary rain, but not severe storms or floods. If these events occur and the chemicals are released, people and the environment may be endangered. This Article discusses the hazards posed to chemical and waste disposal facilities by extreme weather events that would be worsened as a result of climate change, and how U.S. laws do (or do not) deal with these hazards; and considers how the law would need to change to cope with what would happen to these facilities in a potentially 4°C world.

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.

Superfund practitioners are waiting to see whether the U.S. Environmental Protection Agency (EPA) will designate perfluorooctanoic acid and perfluorooctane sulfonate, two chemicals in the per- and polyfluoroalkyl substances (PFAS) group, as CERCLA hazardous substances. Such a designation may lead to selected remedies being modified and further work being required at Superfund sites where remedies were believed to be complete. This Article explores potential future liability by reviewing provisions of the 2021 Remedial Design/Remedial Action (RD/RA) Model Consent Decree.
