This legislation establishes two distinct Geographic Programs aimed at significantly improving water quality and public health in the Tijuana River and New River watersheds. These programs, overseen by the Environmental Protection Agency (EPA) Administrator, will coordinate restoration activities among a wide array of federal, state, tribal, local, and international partners, including Mexican governmental entities. A central component of each program is the development of a comprehensive Water Quality Action Plan . These plans will identify and prioritize projects for pollution prevention, environmental restoration, and climate change resilience. Such projects include those utilizing water reuse , water recycling , and natural and green infrastructure to enhance water quality and reduce runoff. The action plans will also detail estimated costs, potential funding sources, and operations and maintenance needs for both existing and new infrastructure. They are required to build upon existing efforts and incorporate projects identified in previous environmental impact statements. A priority list of projects will be developed for both the U.S. and Mexican portions of the watersheds, specifically targeting transboundary flows. The bill authorizes substantial funding, with $50,000,000 annually for each river from fiscal years 2026 through 2036 , to support these restoration efforts. The EPA Administrator is empowered to provide grants, technical assistance, and enter into interagency agreements with various entities in both the United States and Mexico. The Commissioner of the International Boundary and Water Commission (IBWC) is also authorized to construct, operate, and maintain projects identified in the action plans, including those within the United States and, through agreements, in Mexico. Beyond the specific river programs, the legislation creates a broader United States-Mexico Border Water Infrastructure Program . This program will offer financial and technical assistance for eligible projects related to drinking water, wastewater, and stormwater management within 100 kilometers of the border. Projects are prioritized based on their positive environmental and public health impacts, benefits to the U.S. side, and their focus on sustainable practices. Extensive coordination is mandated with federal, state, local, tribal, and Mexican governmental entities, as well as the North American Development Bank. The President is required to submit annual budget plans detailing estimated expenditures for these projects. Furthermore, the EPA Administrator must submit biennial reports to Congress, describing funded projects, their status, and assessing their effectiveness.
