Mississippi River Corridor Restoration and Resilience Grant Program Act

This Act establishes the Mississippi River Corridor Restoration and Resilience Grant Program. The purpose is to provide federal financial assistance to states and Indian tribes within the Mississippi River Corridor for projects that restore water quality, enhance flood resilience, and improve fish and wildlife habitat, where such projects have a direct and substantial effect on interstate commerce, including navigation, flood control, and water supply for downstream states. Eligible projects include wetland restoration, agricultural best management practices to reduce nutrient runoff, levee setbacks, and reconnection of floodplains. To receive a grant, a state or tribe must submit a plan that demonstrates the project's interstate commerce nexus and must provide a 25% non-federal match. No grant may be used to acquire land by eminent domain or to impose new federal regulations on private land use. The program is administered jointly by the Administrator of the Environmental Protection Agency and the Chief of Engineers of the Army Corps of Engineers. They shall establish a Mississippi River Corridor Task Force with representatives from each eligible state and tribe to prioritize projects. Funding is authorized at $200 million per year for fiscal years 2026 through 2030, to be appropriated from the general fund. This amount is offset by reducing premium subsidies for federal crop insurance on lands within the 100-year floodplain of the Mississippi River by 5% over the same period. The program sunsets on September 30, 2030. The Government Accountability Office shall submit a report to Congress on the program's effectiveness and interstate commerce benefits by June 30, 2029. Enforcement: If a grant recipient fails to comply with the terms of the grant agreement, the Administrator may withhold further payments and require repayment of funds used for non-compliant activities, after notice and opportunity for hearing.
