Today, U.S. Environmental Protection Agency (EPA) announced more than $4.4 million in Brownfields Multipurpose, Assessment and Cleanup (MAC) grants to accelerate the cleanup of polluted sites across Oklahoma. With these funds, EPA is investing directly in American communities to cleanup and redevelop blighted properties, delivering on the Trump Administration’s commitment to ensure that clean air, land, and water goes hand-in-hand with economic growth and opportunity.
“EPA is focused on delivering practical results that transform contaminated properties into clean, valuable spaces that spark economic growth and that directly benefit American families,” said Acting Assistant Administrator for Land and Emergency Management Thomas Croci. “Addressing environmental contamination and reusing brownfield properties revitalizes neighborhoods, drives local job creation, and unleashes new economic opportunities. EPA is proud to partner with local communities to ensure they have the cleanest air, land, and water as we power the Great American Comeback.”
“This funding provides local communities in Oklahoma the tools to assess and clean up contaminated sites to bring them back into economic use,” said Regional Administrator Scott Mason. “EPA’s Brownfields program is the perfect example of accomplishing two goals at once—protecting the environment and powering our nation’s economy.”
Clean air, land, and water for all Americans is the first pillar of President Trump and Administrator Zeldin’s Powering the Great American Comeback initiative. These grants put that commitment into action while simultaneously powering economic growth in communities across the country. Selected applications for the 2026 Brownfield Multipurpose, Assessment, and Cleanup Grants and RLF supplemental funding in Oklahoma include:
