Clean Water Act of 2023

HR 5983, the Clean Water Act of 2023, redefines "protected water resources" under federal law to explicitly include all interstate and intrastate waters (such as intermittent and ephemeral streams), wetlands, and their tributaries. This directly affects federal agencies like the EPA, states managing water quality, and developers or landowners needing permits for activities near these waters. The bill eliminates the Supreme Court’s narrow "navigable waters" definition from Sackett v. EPA (2023), restoring protections for tens of millions of acres of wetlands and millions of miles of small streams. Key mechanisms require the EPA to annually review and adjust exclusions from protections based on scientific evidence, ensuring water bodies critical to drinking water, flood control, and ecosystems remain safeguarded.
