What Is the Alligator Alcatraz Environmental Lawsuit?

Three separate lawsuits make up the Alligator Alcatraz lawsuit story: an environmental case brought under the National Environmental Policy Act, a Clean Air Act case over diesel generator emissions, and a class action filed on behalf of detainees over access to their attorneys. All three were active as of mid-2026, with the environmental case back before a federal district judge after the Eleventh Circuit vacated a preliminary injunction, the air pollution case in its early stages, and the access-to-counsel case on appeal.¹²

The facility sits on the grounds of the Dade-Collier Training and Transition Airport in Ochopee, Florida, inside the Big Cypress National Preserve and surrounded by Everglades National Park and the Miccosukee Tribe’s reservation. The site is more than 96 percent wetlands.³ It was built in eight days in June 2025 after Governor Ron DeSantis invoked emergency powers, with roughly 800,000 square feet paved and the operation running on FEMA trailers, tents, portable generators, and industrial flood lighting.⁴⁵ No environmental review was prepared before construction began.⁶

The NEPA Lawsuit: Friends of the Everglades v. Noem

On June 27, 2025, Friends of the Everglades and the Center for Biological Diversity sued in the U.S. District Court for the Southern District of Florida, case number 1:25-cv-22896. The defendants were the U.S. Department of Homeland Security, ICE, the Florida Division of Emergency Management, and Miami-Dade County. The plaintiffs are represented by Earthjustice, Scott Hiaasen, and Paul Schwiep of Coffey Burlington.¹⁷

The complaint rests on two main theories. First, the project violated the National Environmental Policy Act because no environmental impact statement or assessment was prepared, no categorical exclusion was invoked, and no emergency exemption was claimed. Second, the construction amounted to unlawful final agency action under the Administrative Procedure Act. The complaint also alleged violations of a Miami-Dade County code restricting the airport site to aviation uses.¹⁶ Florida’s defense was that NEPA did not apply because the detention center was a state project.⁸

The Miccosukee Tribe Joined the Case

The Miccosukee Tribe of Indians of Florida moved to intervene on July 14, 2025. The tribe’s reservation lies within miles of the facility, and its Panther Clan village sits roughly 1,000 feet from the site.⁹ The tribe alleged the facility was built without the tribal consultation required by federal law, and that light pollution disrupted spiritual practices tied to dark skies and the orientation of the stars during corn dance season.¹⁰¹¹ Judge Kathleen Williams granted the motion on July 30, 2025, making the tribe a full party.¹

The Preliminary Injunction

After a four-day evidentiary hearing in August 2025, Judge Williams issued an 82-page ruling on August 21, 2025, granting a preliminary injunction. She found that the state and federal government had acted “in flagrant violation of environmental law” by paving 20 acres and installing infrastructure inside the Big Cypress National Preserve without public input or any environmental assessment. The judge rejected the argument that the project was purely state-run, concluding that federal involvement brought it within NEPA.¹²¹³

The order blocked new lighting, paving, or construction; barred transferring additional detainees to the site; and required removal of temporary fencing, industrial lighting, and waste infrastructure within 60 days. The roughly 900 detainees already there were allowed to remain while the population wound down.¹⁴

The Eleventh Circuit Reversed

State officials appealed immediately. On September 4, 2025, an Eleventh Circuit panel stayed the injunction pending appeal, reasoning that the defendants were likely to succeed on the merits because, at that point, the facility appeared state-controlled and had received little or no federal funding.¹⁵ Operations resumed.

On April 21, 2026, the Eleventh Circuit issued a split decision vacating the injunction in full. Chief Judge William Pryor, joined by Judge Brasher, held that the plaintiffs failed to identify a final agency action under the APA or a major federal action under NEPA. The majority concluded that Florida built the facility with state funds on state-managed land, that federal immigration authority over detainees was distinct from the construction decisions that would trigger NEPA, and that the injunction violated a federal statute barring courts from enjoining the operation of certain immigration enforcement provisions.¹⁶

Judge Abudu dissented. She argued the majority had ignored the district court’s factual findings and failed to apply a deferential standard of review, and wrote that the federal government could not “abdicate its responsibility” to comply with NEPA by partnering with the state while avoiding formal agreements. She pointed to the scale of the facility, federal post-construction oversight, and the operational role of immigration officials as evidence of federal action.¹⁶ The case was remanded to Judge Williams for further proceedings.¹

The $608 Million Federal Grant

The question of federal involvement shifted after the appeal was briefed. On September 30, 2025, FEMA awarded Florida $608.4 million through the Detention Support Grant Program for Alligator Alcatraz and related facilities; Florida was the sole applicant. ICE separately awarded $38 million for equipment and transportation.¹⁷ FEMA initially placed an environmental and historic preservation hold on the grant and lifted it in March 2026.¹⁸ On remand, the central question is whether that federal money now supplies the funding connection the Eleventh Circuit majority said was missing.¹⁹

The Clean Air Act Lawsuit

On May 27, 2026, the Center for Biological Diversity filed a separate suit in the Southern District of Florida against Kevin Guthrie, executive director of the Florida Division of Emergency Management. The case, number 1:26-cv-23710, was assigned to Judge Federico A. Moreno.²⁰

The complaint alleges the facility has operated since June 2025 with industrial diesel generators powering air conditioning, flood lighting, and a staff village without the air pollution permits required under the Clean Air Act. According to the Center, Alligator Alcatraz uses more than 100 diesel lighting towers and between 25 and 200 generators consuming over 7.6 million gallons of fuel per year, releasing benzene, formaldehyde, nitrogen oxides, and particulate matter. The suit estimates the site has the potential to emit at least 509 tons of carbon monoxide and 204 tons of nitrogen oxides annually.²¹²²

The Center chose the Clean Air Act because, unlike NEPA, its permit requirements apply to both state and federal facilities, which sidesteps the control dispute that undid the first injunction. Staff attorney Ryan Maher said the organization intended to hold the state accountable “until every dirty diesel generator is removed from the site.” The complaint notes that violations can carry civil penalties of up to $124,426 per day.²²²³

The Detainee Access-to-Counsel Class Action

A third lawsuit addresses conditions inside the facility rather than its environmental footprint. In H.C.R. v. Noem, case number 2:25-cv-00747, detainees represented by the ACLU, Americans for Immigrant Justice, and other legal organizations alleged they were denied the ability to communicate with attorneys and deprived of basic materials like paper and pencils.²⁴

On March 27, 2026, Judge Sheri Polster Chappell of the Middle District of Florida provisionally certified the class to cover all current and future detainees and granted a preliminary injunction. The order required ICE to provide confidential legal phone access, publish clear protocols for attorney-client communication, and allow attorneys to visit without scheduling in advance.²⁴ At an April 13, 2026 status conference, Judge Chappell said compliance had been slow and that information posted on ICE and FDEM websites did not meet the terms of her order. She noted the FDEM site provided only a contact email with no visiting hours, legal information, or feedback options. The Florida Division of Emergency Management has appealed to the Eleventh Circuit.²

What the Environmental Suits Say Is at Stake

Expert witnesses and plaintiffs identified the Florida panther, wood storks, bonneted bats, and Everglades snail kites as endangered or threatened species at risk from the facility.²⁵ Only an estimated 120 to 230 adult panthers remain in the wild, and the site falls within what biologists describe as the panther’s core territory.⁸ Panther specialist Randy Kautz testified at the August 2025 hearing that the facility’s artificial light and human activity could drive panthers away, and estimated the industrial lighting alone reduced usable habitat by roughly 2,000 acres.²⁶

NASA satellite imagery from late June to early July 2025 confirmed bright anthropogenic light emissions at the site inside the otherwise dark preserve, which received an International Dark Sky Place designation in 2016. Experts testified the glow was visible 20 to 30 miles away.²⁷²⁵ Hydrologists warned that roughly 800,000 square feet of new paving had been installed without a stormwater treatment system, allowing pollutants to flow into the surrounding watershed, which supplies drinking water for millions of South Floridians and the Miccosukee Tribe downstream.²⁸⁴

Where Things Stand

As of early June 2026, the Department of Homeland Security said “daily operations continue as usual” at Alligator Alcatraz, and the estimated annual operating cost was $1.4 billion.²⁹ Reports indicated the DeSantis administration was in negotiations with DHS about a possible closure, though no date had been announced, and the governor has said the facility was never intended to be permanent.³⁰ U.S. Rep. Maxwell Frost, a Florida Democrat, said after a late May 2026 visit that he saw more than 600 detainees and that activity appeared to be winding down.

The NEPA case is back before Judge Williams on remand, with the FEMA grant now the central factual question. The Clean Air Act case is in its early stages before Judge Moreno. The access-to-counsel class action remains open, with the state’s appeal of Judge Chappell’s preliminary injunction pending at the Eleventh Circuit.¹²
