Federal Waivers Enable Barrier Construction in Big Bend Parks
On June 8, 2026, the Department of Homeland Security (DHS) issued a revised notice of determination that waives dozens of federal environmental statutes—including the National Park Service Organic Act, Endangered Species Act, National Wild and Scenic Rivers Act, Native American Graves Protection and Repatriation Act, and Archaeological and Historic Preservation Act—to “ensure the expeditious construction of barriers and roads” along the Texas-Mexico border segment that runs through Big Bend National Park and Big Bend Ranch State Park. The waiver, effective the following Tuesday, authorizes the full suite of infrastructure—fencing, vehicle barriers, patrol roads, lighting, cameras and sensors—within the protected lands.
Background: Prior Protections and Recent Policy Shift
Big Bend National Park, covering more than 800,000 acres of Chihuahuan Desert, mountains and the Rio Grande, has long been managed under the National Park Service Organic Act, which mandates preservation of natural and historic values. Historically, the National Park Service and its law-enforcement officers have conducted limited immigration-control activities while protecting visitor experiences. The 2026 waivers represent the first instance of a federal administration discarding such a broad slate of environmental protections inside a national park.
Key Actors, Contracts and Funding
- DHS: Issuer of the waivers and overseer of the construction program.
- Customs and Border Protection (CBP): Implements the barrier and surveillance components; its public map now shows only vehicle-type barriers and patrol roads, not a 30-foot wall.
- Kristi Noem (former DHS Secretary): Personally approved two contracts for SLSCO Ltd., a Texas-based firm also linked to the “Alligator Alcatraz” camp in Florida.
- SLSCO Ltd.: Recipient of a $1.7 billion contract (May 2026) explicitly described as “for border wall through Big Bend.”
- Additional Funding: A later award of $2.6 billion (some reports cite $6 billion) for the Lower Canyons stretch of the Wild and Scenic Rio Grande, the costliest border-construction deal in federal history.
Data & Statistics on Border Activity and Funding
- The Big Bend sector accounts for roughly 100 miles of the U.S.–Mexico border, representing 26.5 % of the total border length.
- Migrant apprehensions in the sector have fallen dramatically: CBP data show a 74 % decline from 11,823 apprehensions in fiscal 2023 to 3,096 in fiscal 2025, comprising 1.3 %–2 % of nationwide totals (sources differ).
- Over 130 organizations, outfitters and rural Texas businesses have urged Congress to block further federal funding for barrier construction in the area.
Official Statements & Agency Responses
DHS explained that the waivers are “necessary to ensure the expeditious construction of barriers and roads” in the vicinity of the international land border. The agency later clarified that the original notice contained an “incorrect” project-area description, prompting the revised determination. CBP’s publicly released map indicates no planned 30-foot wall inside the park but does show vehicle barriers, new patrol roads and expanded surveillance equipment. DHS Secretary Marywayne Mullin received a letter from seven former park superintendents urging a reversal of the waivers; the department has not publicly responded to that specific request.
Criticism, Legal Challenges & Opposition
The Center for Biological Diversity (CBD) filed a Freedom of Information Act suit in April to obtain construction plans and a separate lawsuit invoking the “major questions doctrine,” arguing that the waivers exceed congressional authority. Seven former Big Bend superintendents jointly wrote to DHS Secretary Mullin urging a halt to the waivers. Indigenous groups and archaeologist David Keller warned that the “military industrialization” threatens millennia-old cultural sites. The No Big Bend Wall Coalition highlighted that the sector’s low apprehension rates contradict the administration’s “national emergency” rationale.
Conflicting Reports & Gaps
- Barrier Type: CBP’s map shows only vehicle barriers, while the waiver authorizes full-scale fencing, lighting and sensors.
- Funding Amount: Sources report the Lower Canyons contract as $2.6 billion and as $6 billion, creating a discrepancy.
- Apprehension Share: Reported sector share of total apprehensions ranges from 1.3 % to 2 %.
- Project Timeline: Texas Public Radio cites construction beginning “within weeks,” but DHS has not released a definitive start date.

- “The only people benefiting from this destruction are the billionaire contractors set to pad their pockets while paving over our natural heritage and permanently locking a great American river behind hideous steel barriers.” — Laiken Jordahl
- “These horrific plans are an affront to the millions of Americans who treasure Big Bend,” — Laiken Jordahl
- “If a border wall—or other unnecessary and highly destructive border infrastructure—is built inside Big Bend National Park, it would be the most egregious assault on the integrity of the entire National Park System since the construction of a dam in the Hetchy Hetchy Valley in Yosemite National Park more than a century ago,” — Former superintendents of Big Bend National Park

What’s Next
DHS plans to commence barrier construction in the coming weeks, pending final procurement steps. Litigation by the Center for Biological Diversity and Indigenous advocates is ongoing, with court rulings expected to shape the scope of the waivers. Congressional action on funding restrictions remains a focal point for the coalition of over 130 environmental and business groups.
