Navajo-Gallup Water Supply Project Amendments Act of 2025: key changes to authorization, trusts, and land-into-trust

Updates the original Northwestern New Mexico Rural Water Projects Act to expand service areas, create a Deferred Construction Fund, revise funding authorizations, establish settlement trust rules, and clarify land, tax, and water-delivery rules.

The Brief

The bill amends the Northwestern New Mexico Rural Water Projects Act to recalibrate what facilities are authorized for the Navajo-Gallup Water Supply Project, update definitional language, and change financing and implementation mechanics. It explicitly incorporates the Bureau of Reclamation’s October 2022 Working Cost Estimate into the authorization, raises the authorized federal funding ceiling to $2.175 billion (FY2009–FY2029), and creates a new Navajo Nation Deferred Construction Fund for portions of the Project the Nation and the Secretary agree to defer.

Beyond money and timing, the bill addresses land and governance: it directs the Department of the Interior to take title to specific project parcels into trust for the Navajo Nation (while preserving perpetual easements and certain federal facility ownership), creates three named Settlement Trust Funds with investment and withdrawal rules, limits state and local taxation on activities occurring on trust land, and permits constrained delivery of non‑Project water to Utah Navajo communities subject to compact accounting and funding guardrails. These changes reallocate risk, introduce new financial tools, and tighten the legal framework that will govern construction, operation, and long‑term financing of the Project.

At a Glance

What It Does

The bill revises project definitions, incorporates the Bureau’s October 2022 Working Cost Estimate as part of the authorized configuration, raises the federal appropriation cap to $2.175 billion, allows agreed deferred construction with deposits into a new Deferred Construction Fund, and authorizes specified trust funds and investment rules for Navajo and Jicarilla trust accounts.

Who It Affects

Directly affected parties include the Navajo Nation and Jicarilla Apache Nation (as trust beneficiaries and project participants), the City party to the original project contract (with a new $76 million repayment cap), the Bureau of Reclamation (as project manager and trustee), and New Mexico, Arizona, and Utah entities that interact with project facilities or tax bases.

Why It Matters

The bill turns cost estimates and project configuration into statutory authorization, creates a mechanism to postpone construction without losing federal commitments, and swaps a patchwork of operational arrangements for a set of named trust funds and clearer land‑into‑trust instructions—moves that will shape who pays, who controls, and when parts of the project get built.

What This Bill Actually Does

The bill rewrites key definitions and folds the Bureau of Reclamation’s October 2022 Working Cost Estimate into the Project’s authorized footprint. That changes what Congress has statutorily approved: the Project is now to be built “as configured” in the Working Cost Estimate and applicable NEPA supplements, rather than solely as described in earlier draft materials.

The bill also modernizes language (for example, consistently replacing references to “Draft” with “Final Environmental”) to reflect the Project’s matured environmental record.

On scope, the Navajo Nation may expand the Project Service Area into the Rio San Jose Basin (New Mexico) and, subject to conditions, to Lupton, Arizona in the Little Colorado River Basin. The bill authorizes the United States to acquire and convey specified project lands and facilities (including detailed parcel descriptions), places those parcels into trust for the Navajo Nation, and preserves a perpetual easement and continued federal ownership for water conveyance and storage facilities underlying the San Juan Generating Station unless those facilities are later conveyed.Money and timing are major changes.

The authorization ceiling rises to $2,175,000,000 for FY2009–FY2029, with indexing rules to adjust for post‑October 2022 cost changes and limited mechanisms to capture unforeseen market volatility. The bill establishes three Settlement Trust Funds (a Navajo Development Trust Fund, a Navajo Operations/Maintenance/Replacement Trust Fund, and a Jicarilla Operations/Maintenance/Replacement Trust Fund) with specified authorized deposits, investment rules tied to existing trust statutes, managed‑fund withdrawal conditions, and reporting requirements.

It also creates a Deferred Construction Fund that holds federal amounts for facilities the Nation agrees to defer; deposits to that Fund are treated differently for adjustment and deadline purposes and must be used either to build the deferred facilities later or to build agreed alternate facilities consistent with project purposes.Operationally the bill permits use of modest federal funding for renewables and small hydro on project facilities, clarifies who taxes construction/operation activity (Nation taxes activity on land held in trust; states tax activity on non‑trust land), and narrows the City’s repayment obligation with a $76 million cap. Finally, the bill authorizes limited conveyance—up to 2,000 acre‑feet per year—of non‑Project water through Project infrastructure to benefit Utah Navajo communities, but only under a set of conditions that preserve Project participants’ cost shares, preclude federal funding of non‑Project infrastructure, and require compact accounting consistent with the Navajo/Utah Settlement Agreement.

The Five Things You Need to Know

1

The bill raises total federal authorization for the Project to $2,175,000,000 for fiscal years 2009 through 2029 and directs index‑based and Secretary‑determined adjustments for post‑October 2022 cost changes and market volatility.

2

It incorporates the Bureau of Reclamation’s 'NGWSP October 2022 WCE' (Working Cost Estimate) totaling $2,138,387,000 at October 2022 prices into the statutory authorization and any NEPA supplements.

3

The bill creates a Navajo Nation Deferred Construction Fund: federal amounts for facilities mutually agreed to be deferred must be deposited there, and the Nation may later use the fund to build those deferred or agreed alternate facilities; deposits into this Fund are exempt from further index adjustments.

4

It establishes three named Settlement Trust Funds with specific funding rules and limits—most notably a Navajo Nation Operations, Maintenance, and Replacement Trust Fund authorized at $250,000,000 and a Jicarilla O&M&R Trust Fund capped at $10,000,000 (subject to an Ability‑to‑Pay study)—and ties investments to federal Indian trust investment statutes.

5

The bill directs the Secretary to take identified parcels into trust for the Navajo Nation (with precise parcel descriptors), preserves a perpetual easement and retained federal ownership over San Juan Generating Station water facilities unless conveyed, and bars state taxation on construction, operation, and maintenance activities occurring on land held in trust.

Section 2 (Definitions)

Revise definitions and adopt Working Cost Estimate

This section reorganizes and updates the Act’s definitions, adds a formal term for the 'Deferred Construction Fund', replaces references to 'Draft' with 'Final Environmental' and inserts the Bureau’s October 2022 Working Cost Estimate as a defined document. Practically, the change means the Project’s statutory description now points to a specific engineering cost estimate and configuration, narrowing ambiguity about which facilities Congress approved and anchoring later adjustments to that baseline.

Section 3(a) (Project Authorization & Service Area)

Authorize Project per Working Cost Estimate and permit limited service‑area expansion

The Secretary must now treat the Final EIS 'as further refined' by the Working Cost Estimate (and any NEPA supplements) as the authorized Project. The Navajo Nation can expand deliveries into the Rio San Jose Basin (NM) and, subject to conditions, into Lupton, AZ. This codifies both the Project’s technical baseline and a statute-level permission for geographically targeted expansion that could change demand profiles and unit O&M costs.

Section 3(b)-(c) (Facilities, Acquisition, and Land‑into‑Trust)

Acquire and take specified project lands and facilities into trust, with reserved easements

The bill authorizes acquisition of water conveyance and storage facilities tied to the San Juan Generating Station and specifies particular parcels (fee and public domain) for trust status. It directs the Secretary to take legal title and hold identified lands in trust for the Navajo Nation, but also creates a perpetual easement reserved to the United States for ingress/egress, Project construction, and O&M over land underlying the San Juan Generating Station; the federal government retains ownership of certain federal facilities unless conveyed later. These mechanics aim to give the Nation reservation land to operate facilities while protecting federal access and historical facility ownership.

Section 3(h)-(i) (Deferred Construction Fund & Renewable Energy)

New Deferred Construction Fund and limited renewable/hydro funding

The bill allows the Nation and Secretary, by mutual agreement, to defer construction of selected facilities and requires federal amounts tied to those deferred facilities be deposited into a Treasury 'Deferred Construction Fund' for later use on deferred or alternate agreed facilities. It also authorizes up to $6.25 million (of amounts made available under section 10609(a)(1)) to develop renewable energy on Project portions lacking CRSP power and up to $1.25 million of that amount for hydroelectric development. The deferred‑construction mechanic gives the parties a tool to manage near‑term O&M exposure at the cost of delaying capital delivery.

Section 3 & 4 (Project Contracts and City Repayment)

Rewrites contract language and caps City repayment

The bill reworks project contract provisions: it removes a previously conditioned subsection, converts a 'minimum percentage' requirement into a 'maximum percentage' cap for a City’s repayment share, and explicitly caps the City’s repayment obligation at $76 million. That cap reallocates or limits municipal exposure and could require other parties—tribal or federal—to absorb remaining capital costs or seek alternate financing arrangements.

Section 4 & 10702 (Settlement Trust Funds and Timing)

Creates and governs three Settlement Trust Funds with investment and withdrawal rules

The bill replaces the prior single‑trust structure with three named trust funds: (1) Navajo Nation Water Resources Development Trust Fund (with previously authorized deposits and delayed availability tied to court decrees), (2) Navajo Nation Operations, Maintenance, and Replacement Trust Fund (authorized $250M, investable and indexed for O&M cost fluctuations), and (3) Jicarilla Apache Nation O&M&R Trust Fund (created after an Ability‑to‑Pay study; up to $10M). It ties investment authority to longstanding Indian trust statutes, requires Tribal management plans or Secretary‑approved expenditure plans for withdrawals, and makes clear that funds cannot be used for per‑capita distributions.

Section 10609 (Appropriations and Adjustments)

Raise authorization and define adjustment rules

Authorizations increase to $2,175,000,000 and the bill creates an explicit two‑part adjustment authority: one that follows engineering cost indices to capture ordinary inflation and another that permits the Secretary to address unforeseen market volatility that indices may miss. Importantly, funds deposited into the Deferred Construction Fund are carved out from these indexing adjustments, insulating deferred amounts from further repricing.

Section 10610 & Taxation Changes

Tax treatment for construction, operation, and maintenance

New section 10610 allocates taxing authority by situs: construction/operation activities on land held in trust for the Navajo Nation are taxable by the Nation and not by states or political subdivisions; conversely, such activities on non‑trust land remain subject to state and local taxes and not to Nation taxation. The change clarifies tax rules for Project activity but introduces potential fiscal shifts for counties and states that previously collected such taxes.

Section 5 (Non‑Project Water to Utah)

Authorize limited non‑Project water conveyance to Utah Navajo communities, with guardrails

The bill allows up to 2,000 acre‑feet per year of non‑Project water to be treated, stored, or conveyed through Project infrastructure to benefit Navajo communities in Utah, but only if a set of strict conditions are met: no more than 2,000 AF/year; accounting against the Navajo‑Utah water apportionment; no increase in Project participants’ O&M shares as a result; no federal funding for non‑Project infrastructure (with narrow statutory exceptions); and compliance with the Navajo/Utah Settlement Agreement plus an implementation agreement with the State of Utah. This creates an interoperability path but limits federal exposure and obligates compact accounting.

Who Benefits and Who Bears the Cost

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.

Who Benefits

  • Navajo Nation leadership and water planners — gain statutory certainty over project configuration (Working Cost Estimate), authority to take specific parcels into trust, and access to dedicated trust funds and a Deferred Construction Fund to manage capital sequencing.
  • Jicarilla Apache Nation — receives a defined pathway to an O&M&R trust fund (subject to an Ability‑to‑Pay study) to cover operation, maintenance, and replacement costs for Project segments serving the Jicarilla service area.
  • Rural communities within expanded service areas (Rio San Jose Basin and Lupton, AZ) — obtain a statutory route to receive Project water if included under the permitted expansion, potentially lowering long‑term per‑customer O&M costs by enlarging the customer base.
  • Project operators and the Bureau of Reclamation — benefit from clearer acquisition authority, land‑into‑trust direction, and a defined fund structure that ties funding, investment, and withdrawals to federal trust statutes, reducing legal uncertainty about fund management.
  • Utah Navajo communities — gain a constrained but concrete option (up to 2,000 AF/year) to receive non‑Project water through Project infrastructure, subject to compact accounting and implementation agreements.

Who Bears the Cost

  • Federal Treasury and appropriations committees — face a higher authorization ceiling ($2.175B) and must support indexed adjustments and authorized trust deposits (including $250M for Navajo O&M&R), increasing fiscal exposure.
  • State and local taxing jurisdictions in affected counties — lose some taxable base where construction/operation occurs on trust land, potentially reducing property and activity tax receipts and complicating local service funding.
  • The City party to the original contract — faces a hard cap on repayment ($76M), which may shift residual capital cost responsibility to other Project participants or the federal government and require reallocation of financing burdens.
  • Bureau of Reclamation and Interior — take on new administrative responsibilities: managing investments under Indian trust statutes, enforcing Tribal management plans and expenditure plans, holding lands in trust while protecting perpetual easements, and administering the Deferred Construction Fund.
  • Project contractors and suppliers — may experience schedule uncertainty and rephasing risk where the Nation and Secretary defer construction, which could affect contracts, cash flow, and pricing in the near term.

Key Issues

The Core Tension

The bill balances tribal self‑determination and long‑term financial security (via land‑into‑trust, named settlement trust funds, and a Deferred Construction Fund) against state and local fiscal interests and the federal government’s exposure: giving the Navajo Nation statutory control and tax base for Project activity reduces state/local revenue and complicates obligations for federal agencies and other Project participants, producing a trade‑off between sovereignty, cost‑containment, and shared fiscal responsibility.

The bill creates tools to manage cost and schedule but leaves several operational tensions unresolved. First, taking specific parcels into trust while reserving perpetual easements and retaining federal facility ownership creates a layered title regime: the Nation gets trust land and taxation rights, but the United States keeps essential access and in some cases facility title.

That division protects federal operations but complicates transferability, liability, and long‑term maintenance responsibilities.

Second, the Deferred Construction Fund gives the Nation flexibility to postpone capital work without forfeiting federal deposits, but it also converts near‑term construction responsibilities into a future obligation that may increase future cost, reduce immediate service delivery, or introduce opportunity costs if deferred facilities become more expensive to build later. Linked to this is the bill’s carve‑out that deferred amounts are not subject to later adjustment—good for price certainty now, but risky if market volatility later reduces the purchasing power of the deposit.

Third, trust fund mechanics and withdrawal controls are legally robust but operationally heavy: Tribal management plans, Secretary approvals, and Secretary enforcement create governance friction. Investment returns will matter; tying investments to existing Indian trust statutes limits investment options and exposes beneficiaries to market and interest‑rate risk.

Finally, permitting up to 2,000 acre‑feet/year of non‑Project water to Utah Navajo communities is administratively possible but legally sensitive because it requires compact accounting and strict non‑use of Project funds for non‑Project infrastructure—a setup that could generate disputes between states over depletion accounting or provoke local actors if costs or compact impacts materialize.
