The latest season of Clean Water Act (CWA) changes are now streaming from the courts and federal agencies. The Biden administration and lower courts have picked up where prior administrations and the U.S. Supreme Court left off, as we reported last year in Binge-Watching the Clean Water Act Cases and Rules. Unless Congress somehow finds bipartisan support for legislative fixes, we expect contentious CWA rulemaking proceedings to resume and protracted CWA litigation to prosper. These actions constrain land developers, utilities and companies on projects or operations that impact wetlands or other water features. These decisions might also give environmental groups and agencies stronger grounds on which to base CWA claims targeting sewers, pipelines, tanks, and other systems that leak or seep wastes into groundwater.
