This Act would authorize and expedite a land exchange between the United States and the Chugach Alaska Corporation. It centers on trading approximately 231,000 acres of subsurface land owned by Chugach Alaska for roughly 65,374 acres of Federal land within the Chugach Region, as identified in the Chugach Region Land Study and Report.
The exchange is designed to consolidate surface and subsurface estates to advance the Exxon Valdez Oil Spill Habitat Protection and Acquisition Program while honoring existing Native land entitlements under ANCSA.
The bill lays out the authorization, findings, and definitions that frame the exchange, including the critical goal of resolving split ownership between surface rights held by EVOSTC-initiated acquisitions and subsurface rights retained by Chugach Alaska. It also specifies that land conveyed to Chugach Alaska will be treated as land conveyed under ANCSA, and it sets forth the process, protections for existing rights, and requirements for maps and land descriptions to govern the exchange.
At a Glance
What It Does
Not later than 1 year after enactment, if Chugach Alaska offers to convey the non-Federal land, the Secretary shall accept and convey all rights in the Federal exchange land. Title to the non-Federal land must be in a form acceptable to the Secretary. Land conveyed to Chugach Alaska is treated as ANCSA land, with existing rights reserved.
Who It Affects
Chugach Alaska Corporation and its Alaska Native shareholders; EVOSTC and the Exxon Valdez restoration program; Interior Department bureaus (BLM, Forest Service, NPS) administering the lands; the State of Alaska and the regions affected by the exchange.
Why It Matters
Consolidates ownership to simplify management, advance habitat protection, and align surface and subsurface interests with ANCSA and the EVOSTC program, reducing legal and logistical frictions in long-term land stewardship.

What This Bill Actually Does
The bill codifies a major land swap in the Chugach Region. Chugach Alaska would transfer its subsurface interests in about 231,000 acres to the United States, and in return would receive approximately 65,374 acres of Federal land currently managed by federal agencies.
The exchange is designed to resolve long-standing split ownership created by historical EVOSTC acquisitions that bought surface estates while leaving subsurface rights with Chugach Alaska. The exchange lands would be administered as part of their respective Federal land units, and the transfer would be subject to any valid rights or encumbrances in place at the time of enactment.
A subset of lands is explicitly excluded from conveyance to protect Village Corporations’ development rights and shareholder sites (up to 209 acres). The bill also lists specific Federal lands to be conveyed and details that maps and acreage descriptions may be corrected by mutual agreement if needed, with the map controlling in case of conflict.
This framework supports streamlined land management and habitat protection under the Exxon Valdez Oil Spill Trustee Council’s program, while honoring ANCSA-derived entitlements and regional interests.
The Five Things You Need to Know
The bill requires Chugach Alaska to convey all rights to its non-Federal land, with the Secretary accepting and exchanging for Federal lands within 1 year of enactment.
Approximately 231,000 acres of subsurface estate will be transferred from Chugach Alaska to the United States, while about 65,374 acres of Federal land will be exchanged to Chugach Alaska.
The exchange includes a detailed list of Federal lands to be conveyed (63,414 acres of surface land and 1,960 acres managed by BLM/NPS) and requires administration within existing federal units.
Village Corporation development rights and shareholders' sites are protected by excluding up to 209 acres from the conveyance.
Maps, acreage estimates, and land descriptions can be corrected by mutual agreement, with a map controlling in any conflict.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short Title
This Act may be cited as the Chugach Alaska Land Exchange Oil Spill Recovery Act of 2025.
Purposes and Findings
The bill lays out Congressional findings about past Exxon Valdez spill responses, the EVOSTC program, and the need to consolidate surface and subsurface estates. It frames the exchange as a tool to improve land management and support habitat protection while addressing historical ownership splits created under ANCSA.
Definitions
Key terms are defined to ground the exchange: Chugach Alaska, non-Federal land, Federal exchange land, the Program (Exxon Valdez Oil Spill Habitat Protection and Acquisition Program), and the Secretary (Secretary of the Interior). The definitions tie the exchange to ANCSA, the program’s conservation priorities, and the land-trust framework used in Alaska.
Land Exchange
This is the core mechanism. Not later than 1 year after enactment, if Chugach Alaska offers to convey the non-Federal land, the Secretary shall accept and exchange for the Federal land. Land titles must be acceptable to the Secretary, and conveyances are subject to existing rights. After the exchange, the Federal exchange lands and the non-Federal lands will be administered as units of their respective Federally managed areas. A 209-acre exclusion protects village development rights and shareholder sites.
Maps, Estimates, and Descriptions
The bill provides for minor corrections to maps and acreage estimates by mutual agreement. In case of conflict, the map controls unless both parties agree otherwise. This ensures the exchange can proceed with precise land accounting and administrative clarity.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Chugach Alaska Corporation and its Native shareholders, who gain clarified land and managed subsurface interests.
- EVOSTC and the Exxon Valdez habitat protection program, which benefits from consolidated land management to advance restoration goals.
- U.S. Interior agencies (BLM, Forest Service, NPS) through simplified unit administration and clearer jurisdiction over lands.
- State of Alaska and regional stakeholders who rely on coherent land planning and habitat outcomes.
Who Bears the Cost
- Village Corporations: development rights and shareholder sites are carved out from the exchange (up to 209 acres), potentially limiting some development plans.
- Chugach Alaska: must undertake the conveyance and navigate exchange mechanics and potential regulatory requirements, though gains in subsurface clarity are anticipated.
- Federal land management agencies: administrative costs and potential complexities in reconciling multiple land statuses and conservation easements during the transition.
Key Issues
The Core Tension
The central dilemma is whether consolidating surface and subsurface ownership through a negotiated land exchange adequately protects Native subsurface rights and village development interests while delivering the conservation and administrative efficiencies sought by the EVOSTC program.
The exchange rests on a delicate balance between conservation, native entitlements, and economic development. While it resolves a split-estate dynamic that has complicated subsurface use, it also narrows the land available for village development by excluding certain parcels.
Mapping and description accuracy are critical, since small errors could stall or complicate the exchange. Implementation will require careful coordination among the EVOSTC program, ANCSA entities, and federal land managers to ensure that conservation obligations and subsurface rights are respected throughout title transfers and subsequent administration.
