This legislation, known as the Brownfields Reauthorization Act of 2025, aims to continue and enhance federal support for the cleanup and redevelopment of contaminated brownfield sites. It reauthorizes significant funding for brownfields revitalization and state response programs under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) for fiscal years 2026 through 2030. Specifically, the bill increases the annual appropriation for brownfields revitalization from $200 million to $250 million for the reauthorized period. It also raises the maximum grant amount available for the remediation of individual brownfield sites from $500,000 to $1,000,000 . Furthermore, the bill updates the language for state response programs to include the ability to "implement" such programs, ensuring continued support for state-led cleanup efforts.
