The Brownfields Revitalization for a Better Tomorrow Act amends federal environmental law to expand funding and support for cleaning up and reusing contaminated industrial and commercial properties known as brownfields. The bill increases grant limits for remediation activities from $500,000 to $1,000,000 per site, doubles multipurpose brownfields grants from $1,000,000 to $2,000,000, and allows recipients to use up to 10 percent of funds for demolition. The legislation authorizes $123,500,000 annually for fiscal years 2027 through 2031 for brownfields programs, with additional funding of $46,250,000 per year for state and tribal assistance programs, and creates new technical assistance grants to help small communities that previously failed to secure funding. The bill also directs the Environmental Protection Agency to develop guidance for streamlining federal permitting on brownfield sites and requires multiple studies and reports on revolving loan funds, loan program feasibility, and the National Priorities List deletion process to be completed by 2028–2032.
