The Border Water Quality Restoration and Protection Act directs the EPA to establish two Geographic Programs — one for the Tijuana River watershed and one for the New River watershed — to plan, prioritize, and fund projects that reduce transboundary sewage, stormwater, sediment, and other contaminants. Each program requires an EPA Program Director, a stakeholder management conference, a science-based action plan with a priority project list, and authority to make grants, enter cooperative agreements, and partner with the North American Development Bank for grant management.
Why it matters: the bill creates a sustained federal framework for a problem that crosses the international boundary: chronic beach closures, public-health risks, and ecosystem degradation. It pairs planning (action plans and priority lists) with funding (authorizations of $50 million per program per year for FY2026–2036, grant authority, and a Border Water Infrastructure program) and explicitly pushes EPA to assess operations and maintenance funding — a central gap in prior investments.
The measure also formalizes roles for the U.S. Section of the International Boundary and Water Commission and for coordination with Mexican counterparts.
At a Glance
What It Does
Requires EPA to establish two Geographic Programs (Tijuana River and New River) with Program Directors who must convene stakeholder management conferences, produce action plans and priority project lists, and administer grants and cooperative agreements. Authorizes $50 million per fiscal year for each program (FY2026–2036), creates a United States–Mexico border water infrastructure program, and gives the U.S. IBWC authority to construct and operate selected projects.
Who It Affects
Local governments and wastewater utilities in San Diego County, Imperial County, Calexico, Mexicali, and Tijuana; the U.S. Section of the International Boundary and Water Commission; EPA Regions (primarily Regions 9 and 6); the North American Development Bank; Border Patrol and federal land managers; and Mexican agencies such as CONAGUA and municipal utilities.
Why It Matters
The bill federalizes coordination for long‑running transboundary pollution problems, dedicates recurring federal funding to both planning and construction, emphasizes natural and green infrastructure and water reuse, and addresses the underfunded operations-and‑maintenance piece that has limited the durability of prior investments.

What This Bill Actually Does
The Act is organized into four titles that collectively shift border pollution work from ad hoc efforts into structured federal programs. Titles I and II create parallel EPA 'Geographic Programs' for the Tijuana River and the New River.
For each watershed EPA must appoint a Program Director within 180 days and convene a management conference under Clean Water Act section 320 to coordinate Federal, State, Tribal, local, nonprofit, and Mexican counterparts. The Program Director has explicit duties: integrate planning across agencies, solicit stakeholder input, align competing priorities, and facilitate engagement with the U.S.–Mexico International Boundary and Water Commission (IBWC).
Each program must deliver a science‑based action plan within one year that builds on existing studies (including the USMCA mitigation EIS for the Tijuana River), produces a priority project list, and estimates the amounts needed for operations and maintenance. The action plans must be revisited every five years.
The bill requires EPA to develop selection criteria that emphasize measurable, cost‑effective projects — including water reuse, water recycling, natural and green infrastructure — and to fund monitoring, modeling, and other science needed to support project selection.To move projects from plan to construction, EPA may provide grants and technical assistance to a range of recipients (IBWC, states, local governments, tribes, nonprofit organizations, and Mexican entities) and may use the North American Development Bank (NADBank) or a similar organization to manage grants. The statute authorizes $50 million per program per fiscal year for FY2026–2036, allows EPA to set cost‑share rules case‑by‑case, and permits up to 5 percent of appropriations for administration.
Title III establishes a separate border water infrastructure program with eligibility limited to entities within 100 kilometers of the border and defines eligible projects and exclusions (for example, it excludes projects that create new water supply or that enable new development).Title IV clarifies IBWC (Commissioner) authority to study, design, build, operate, and maintain wastewater and stormwater projects, and authorizes agreements with Mexican authorities so projects in Mexico can be jointly developed and, if approved, constructed and funded. The bill also requires the President’s annual budget submission to include estimated expenditures and proposed appropriations for these programs and imposes biennial reporting duties on EPA describing funded projects and assessing operations and maintenance effectiveness.
The Five Things You Need to Know
EPA must establish the two Geographic Programs and designate a qualified Program Director within 180 days of enactment; the Program Director must convene a management conference under Clean Water Act section 320 no later than 120 days after designation.
The bill authorizes $50 million per year for each program (Tijuana and New River) for fiscal years 2026–2036, available until expended (a combined authorization of $100 million annually across the two programs).
Grants may be administered via the North American Development Bank (or similar manager) which can receive an advance payment of annual grant funds and handle grant management; EPA may require payments under cooperative agreements to be deposited into the STAG account.
EPA must issue each action plan within one year, update it every five years, and include a priority project list that (for the Tijuana River) incorporates ‘Alternative 2’ from the USMCA mitigation final programmatic EIS and estimates operations & maintenance costs and potential funding sources.
Title III creates a border infrastructure program that makes assistance available to eligible entities within 100 km of the border and explicitly excludes projects that provide new water supply, reduce ecosystem flows, or enable new development; project prioritization favors those that deliver measurable public‑health and U.S.-side environmental benefits.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Key terms and scope
The bill defines the Administrator (EPA), the Commissioner (U.S. Section, IBWC), the two rivers by geographic description, and operational terms such as 'water reuse' and 'water quality restoration and protection.' These definitional choices determine which projects qualify (for example, water reuse projects are explicitly in scope) and tie the statute to preexisting documents like EPA’s 2020 National Water Reuse Action Plan and the USMCA mitigation EIS. For implementers, the definitions set the perimeter of eligible activity and link program requirements to established federal authorities.
Tijuana River Geographic Program: governance, planning, and grants
Title I creates the Tijuana River Public Health and Water Quality Restoration Program. EPA must appoint a Program Director with specific project management and interagency coordination experience and convene a §320 management conference. The statute requires a one‑year action plan and five‑year updates, instructs EPA to develop a priority list of projects (including projects from the USMCA EIS 'Alternative 2'), and to pursue cooperative agreements with federal, state, local, tribal, nonprofit, and Mexican entities. Importantly, EPA can provide grants, technical assistance, and enter interagency agreements, and may partner with NADBank to administer grants and accept advance payments for grant delivery.
How projects get money and who manages grants
Section 105 lays out grant authority and criteria, allows EPA to set cost‑share requirements on an individual basis, and authorizes $50 million per year (FY2026–2036) for the program with up to 5 percent for administration. The section permits EPA to transfer funds to the Commissioner and to require counterpart payments under cooperative agreements; any such payments are deposited to the EPA STAG account. Practically, this creates both a pool of federal funding and flexibility to use external grant managers to speed project delivery.
New River Program: mirrored structure with regional tailoring
Title II mirrors Title I but targets the New River watershed (Imperial Valley/Salton Sea region). It establishes a California New River Geographic Program that must coordinate with state bodies (Imperial Irrigation District, Salton Sea Authority, Colorado River Basin RWQCB) and Mexican counterparts. The program follows the same planning, grant, and reporting architecture (one‑year action plan, five‑year updates, priority lists) but emphasizes infrastructure elements already in regional planning (trash screens, conveyance, aeration, pump stations, managed wetlands).
United States–Mexico Border Water Infrastructure Program
This section establishes a separate infrastructure program to finance eligible drinking‑water, wastewater, and stormwater projects within 100 kilometers of the border. It provides detailed eligibility rules: projects must address existing health/ecological issues, have U.S. effects, be designed to meet the host country’s standards (and U.S. standards where applicable), and have the legal authority and institutional capacity to operate and finance the service. The statute also lists exclusions (no projects to create new water supply, no projects that reduce ecosystem flows, no projects to enable new development), setting clear guardrails for investments.
IBWC Commissioner authority and U.S.–Mexico agreements
Title IV explicitly authorizes the U.S. IBWC Commissioner to study, design, construct, operate, and maintain wastewater and stormwater projects in the targeted watersheds and to enter into agreements with Mexican authorities under the 1944 water treaty framework. This section is the statute’s operational bridge: it enables binational projects to proceed under IBWC leadership and allows funds appropriated under earlier sections to flow into IBWC activities when the Commissioner is the implementing agent.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Coastal communities in San Diego County (e.g., Imperial Beach): reduced chronic beach closures and fewer public‑health advisories if priority projects are implemented, because the programs prioritize projects that remove bacterial and contaminant loads reaching U.S. beaches.
- Imperial Valley and Calexico region residents: investments in the New River watershed target agricultural runoff, conveyance, pump stations, and managed wetlands that improve local water quality and reduce flood risk while creating local jobs during construction.
- U.S. federal and state environmental managers: EPA, IBWC, and regional water boards gain a structured forum, funding authorization, and legal authority to coordinate across jurisdictions and to incorporate science and monitoring into decisions.
- Water and wastewater utilities and special districts: access to federal grants and technical assistance (including NADBank-managed grants) lowers capital barriers for upgrades, green infrastructure, and water reuse projects.
- Tribes and community organizations within the watersheds: the statute requires consultation and stakeholder engagement, backed by federal funds for monitoring, outreach, and technical assistance that can increase capacity and local influence over project selection.
Who Bears the Cost
- U.S. taxpayers: Congress must appropriate the authorized funds (up to $50M per program per year) and possibly additional funds for transfers to IBWC and other agencies, increasing the federal fiscal footprint for border water infrastructure.
- Local governments and utility districts: projects may be subject to Federal cost‑share or matching requirements determined on a project basis, and local entities will need to participate in planning, permitting, and long‑term O&M funding discussions.
- U.S. IBWC (Commissioner) and implementing federal agencies: the Commissioner may be tasked with construction, operation, and maintenance responsibilities that require staff, oversight, and potentially transferred funds; implementation work may strain IBWC capacity without dedicated appropriations.
- Mexican municipal and state utilities: the bill presumes binational cooperation and may expect Mexican partners to provide counterpart financing, meet design/operational standards, or accept shared project responsibilities — all of which are additional fiscal and operational obligations.
- Grant managers such as NADBank: taking on advance payments and grant administration places operational responsibility on these institutions and may require them to adapt procedures to manage U.S. federal program requirements.
Key Issues
The Core Tension
The central dilemma is between securing fast, visible public‑health benefits on the U.S. side (through prioritized projects and U.S. construction) and the need for durable, upstream fixes in Mexico that require sustained financing, sovereign consent, and enforcement — solutions that are slower, more expensive, and harder to control from Washington. The bill supplies federal planning and capital but leaves the hardest questions — who funds long‑term O&M, who enforces cross‑border standards, and how to equitably share costs between nations and localities — unresolved.
The bill closes several coordination gaps but leaves hard questions about long‑term operations and accountability. It authorizes capital funding and directs EPA to assess O&M needs, yet it does not establish a permanent federal O&M funding stream or clear matching rules for operations across binational projects; establishing sustainable O&M finance will fall to grant recipients, IBWC, states, and Mexican counterparts.
The statute also relies on cooperative agreements and the NADBank to manage grants, an approach that speeds delivery but shifts legal and managerial complexity to third parties and requires careful contracting to protect federal interests.
Another implementation challenge is standard harmonization and enforcement. The Act requires projects, especially those located in Mexico whose discharges affect the U.S., to be designed to meet relevant host‑country standards and, where applicable, U.S. Clean Water Act requirements — but it does not create a new enforcement mechanism for transboundary noncompliance.
That leaves EPA and IBWC to rely on diplomacy, treaty mechanisms, and funding leverage rather than direct regulatory tools when a Mexican facility fails to meet expectations. Finally, the bill prioritizes projects with measurable U.S. benefits; while practical, that prioritization risks underinvesting in upstream Mexican infrastructure that is costly but essential to eliminate pollution at the source.
