AG Nessel Demands ICE Halt Plan to Use Romulus Warehouse as Mass Detention Facility

LANSING – Today, Michigan Attorney General Dana Nessel sent a letter to U.S. Immigration and Customs Enforcement (ICE) objecting to its plan to use a recently purchased warehouse in Romulus as a detention facility for 500 migrants. The Attorney General asserts ICE’s current plan outlined in an Early Notice and Public Review of a Proposed Activity in a 100- to 500-Year Floodplain ignores Michigan’s sovereign interests and federal and state law and must immediately be halted.

“Our system of government and the law demand transparency and partnership with state and local governments,” writes Attorney General Nessel. “But ICE seems determined not just to ignore the need for such cooperation, but to frustrate it. Through its conduct, ICE appears intent to operate a mass detention facility a stone’s throw from a middle school, an elementary school, and a protected wetland. What’s more, ICE purchased the warehouse before any attempt to communicate with the State of Michigan, its agencies, or any local governing body about it.” 

ICE recently released a floodplain notice for its plan to purchase the Romulus warehouse, asking for comments by Friday, February 27, 2026. The Attorney General in her filed comment letter reiterates that the warehouse is not currently designed or outfitted to house, feed, bathe, protect, or provide adequate care for individuals detained by ICE.

Attorney General Nessel argues that the floodplain notice lacks the details necessary to assess whether the project would comply with federal laws, including the National Environmental Policy Act, the Clean Air Act, the Clean Water Act, the National Flood Insurance Act, the Flood Disaster Protection Act, and the Administrative Procedure Act. The property is located within a floodplain, yet ICE has not yet applied for, or even initiated discussions, regarding permits from the Michigan Department of Environment, Great Lakes, and Energy (EGLE).

The Attorney General is calling on ICE to immediately cease further development of the property, plainly and publicly articulate its planned use and construction for the warehouse, engage in meaningful consultation with the appropriate state, county, and municipal officials, and comply with all state and local laws and permitting requirements for the project’s impacts to the environment.
