Environment Hearing: The Impact of U.S. Environmental Laws on Critical Material Supply Chains

The House Committee on Energy and Commerce held a subcommittee hearing on April 15, 2026, to discuss the impact of U.S. environmental laws on critical mineral supply chains, focusing on national security, economic growth, and domestic manufacturing. Witnesses from industry and research organizations testified about challenges in securing domestic supply chains for critical minerals, including regulatory barriers under laws such as the Resource Conservation and Recovery Act (RCRA) and the Toxic Substances Control Act (TSCA). Several witnesses emphasized the need for regulatory clarity, modernization, and consistent environmental standards to attract investment and support domestic mining, processing, recycling, and battery manufacturing. The hearing also addressed the importance of recycling lithium-ion batteries and the need for a unified federal framework to facilitate reuse and recycling while maintaining safety. Members discussed legislative proposals aimed at streamlining permitting processes, clarifying recycling regulations, and incentivizing domestic production and recycling. The hearing highlighted bipartisan concerns about China’s dominance in critical mineral markets and the need for coordinated policy reforms to strengthen U.S. supply chains without compromising environmental protections.
