The Toxic Substances Control Act is the cornerstone of chemical regulation in the United States — but for most of its existence, it was widely considered unenforceable. In this episode of People, Places, Planet's Explained series, host Sebastian Duque Rios is joined by Lynn Bergeson, Managing Partner of Bergeson & Campbell, and Bob Sussman, former senior EPA official and Principal at Sussman & Associates, to break down TSCA from the ground up.

Together, they walk through the foundational building blocks of the law — what chemicals TSCA covers, how Sections 4, 5, and 6 govern testing, new chemical pre-market review, and existing chemical risk evaluation, and why the "unreasonable risk" standard at the heart of the statute proved so difficult to apply in practice. They also trace how the 1991 Corrosion Proof Fittings decision paralyzed EPA's regulatory authority for a generation, and what the 2016 Lautenberg Act fundamentally changed.

Lynn and Bob are co-chairs of the TSCA Reform 10 Years Later conference, taking place June 10th at George Washington University — a free, hybrid event covering risk evaluation, risk management, new chemicals, and the legislative road ahead. The annual conference is co-sponsored by ELI, Bergeson & Campbell, P.C., and the George Washington University Milken Institute School of Public Health.

After the Sackett v. EPA Supreme Court decision stripped back federal Clean Water Act protections, local governments found themselves on the frontlines of wetland conservation — and many have more tools available to them than they realize. In this special American Wetlands Month episode, host Sebastian Duque Rios talks with wetland policy experts and on-the-ground practitioners about what local action looks like in practice.

ELI Senior Attorney Amy Reed introduces the Environmental Law Institute's newly published Local Wetland Protection Playbook — a practical guide to regulatory and non-regulatory strategies for municipalities, landowners, and community advocates. Then we hear two case studies. First, we're joined by Karen Cappiella (Center for Watershed Protection) to discuss how Bluffton, South Carolina became the first municipality in the state to close the post-Sackett loophole through a phased wetland ordinance and updated GIS mapping. Finally, we're joined by Mahtaab Bagherzadeh (National Wildlife Federation) and Nina Struss (Prairie Rivers Network) to learn more about how a bi-state coalition in the Quad Cities region of Iowa and Illinois is using climate assessments, ecological corridor mapping, and collaboration to protect wetlands in the region.

Fifty-six years ago, the first Earth Day helped spark a generation of landmark environmental legislation — and the Environmental Law Institute (ELI) was born from that same moment. On this Earth Day 2026, host Sebastian Duque Rios sits down with ELI President Jordan Diamond and Senior Attorney Jay Austin to trace the arc of environmental law from that founding era to the compounding crises of today.

Together, they reflect on how statutes like NEPA and the Clean Air Act were designed with more foresight than we often credit them for, why adaptive management is baked into the DNA of environmental law, and how ELI is responding to an era of rapid institutional change — from regulatory rollbacks and executive action to the governance challenges posed by emerging industries like deep sea mining, geothermal energy, and data centers. They also dig into ELI's new collaboration with the Federation of American Scientists' (FAS) Center for Regulatory Ingenuity and their joint white paper laying out a framework for rebuilding and reimagining environmental governance fit for the 21st century.

This episode is a candid, long-view conversation about what it takes to protect people, places, and the planet. For more information on other emerging topics in environmental law, see our recent episode, "What's Next for Environmental Law in 2026."
