Gretchen Whitmer’s prior opposition to ICE detention efforts, noting that she had blocked the sale of a state facility because it did not align with her “values,” framing the legal challenge as an effort to impede immigration enforcement.\nMichigan officials argue that federal agencies moved ahead with the purchase and planning of the facility before completing the environmental review required under the National Environmental Policy Act.\nICE purchased the Romulus warehouse in early February. In its response, the government acknowledged the site could ultimately be scaled to accommodate as many as 2,000 detainees, though it said it does not currently expect to house more than 500.\nState officials have cited concerns about wastewater capacity, traffic and the potential strain on local infrastructure if the facility is converted for detention use.\nIn its filing, the government said those harms were speculative, describing them as “contingent” on future decisions about how the facility would be used. It also argued that no final agency action had occurred and that plans for the site were still being developed.\nInternal environmental review documents describe a more defined project.\nA Record of Environmental Consideration, or REC, completed on March 24 — more than a month after the property was purchased and the same day Michigan filed its lawsuit — determined that the project qualified for a categorical exclusion, a streamlined form of review used for actions that “normally do not significantly affect the quality of the human environment.”\nThe document outlines a detention processing center with housing units, recreation areas and support facilities, while stating that the project would involve “no new building additions, footprint expansions, off site construction, or capacity related improvements.”\nIt also concludes that the facility would not exceed existing infrastructure capacity, even as it notes that the project “may require upsizing or modification of the existing sanitary sewer lateral” and references “possible sewer connection improvements,” with final capacity to be confirmed through later engineering and coordination with local authorities.\nDigital signatures show the review was prepared and approved within roughly 30 minutes on the afternoon of March 24.\nThe environmental determination came nearly a month after the property purchase and within hours of the lawsuit, while the government’s court filing describes the project as still evolving and not yet final.\nThe REC also states that the proposed action is “not a piece of a larger action” and does not involve “extraordinary circumstances” that would require more detailed environmental review — findings used to support reliance on categorical exclusions.\nIn its court filing, the government emphasized that additional environmental review is forthcoming, stating that ICE will complete further analysis before undertaking construction or operating the facility.\nThat position follows an earlier internal determination that the project qualified for a categorical exclusion, a form of review used for actions not expected to have significant environmental effects.\nIn a separate case involving a warehouse conversion in Williamsport, Md., a federal judge rejected that approach, finding that DHS relied on categorical exclusions to evaluate a project that would substantially change how the facility functioned. The court wrote that the agency had attempted to “shoehorn” the conversion of a cargo warehouse into exclusions meant for minor renovations and real estate transactions, and that the review itself proceeded at a “rocket’s pace.”\nIn that case, DHS “stacked” multiple categorical exclusions simultaneously — including those for property acquisition and minor facility modifications — to justify bypassing more detailed environmental review. The court found that approach inconsistent with the scale of the project, where the conversion would introduce sustained human occupancy and strain existing infrastructure. Maryland’s request for a preliminary injunction was ultimately granted.\nThe same categories used in the Maryland case — covering real estate acquisition, minor renovations and limited construction — are also invoked in the Michigan review, where the agency determined that converting the Romulus warehouse into a detention facility would not constitute a meaningful change in use or require expanded environmental analysis.\nMichigan is expected to file its reply by April 28.\nTrack this case and others at our updated Warehouse Litigation Tracker, live now at https://tracker.projectsaltbox.com.", "url": "https://wpnews.pro/news/ice-defends-detroit-area-detention-plan-after-same-day-environmental-sign-off", "canonical_source": "https://www.projectsaltbox.com/p/ice-defends-detroit-area-detention", "published_at": "2026-04-22 16:06:57+00:00", "updated_at": "2026-05-24 01:12:58.049815+00:00", "lang": "en", "topics": ["policy-regulation"], "entities": ["ICE", "Department of Homeland Security", "Gretchen Whitmer", "Michigan", "Romulus"], "alternates": {"html": "https://wpnews.pro/news/ice-defends-detroit-area-detention-plan-after-same-day-environmental-sign-off", "markdown": "https://wpnews.pro/news/ice-defends-detroit-area-detention-plan-after-same-day-environmental-sign-off.md", "text": "https://wpnews.pro/news/ice-defends-detroit-area-detention-plan-after-same-day-environmental-sign-off.txt", "jsonld": "https://wpnews.pro/news/ice-defends-detroit-area-detention-plan-after-same-day-environmental-sign-off.jsonld"}}
