This bill establishes new requirements for the Department of Homeland Security (DHS) or any other federal agency before initiating the construction, acquisition, renovation, or operation of, or acquiring real property for, a new processing site or detention center for U.S. Immigration and Customs Enforcement (ICE). These facilities are defined as those used to temporarily hold individuals pending immigration removal operations, including those under the Detention Reengineering Initiative. The legislation aims to increase transparency and local control over the establishment of such facilities. Before proceeding, the relevant federal agency must issue a public notice in the Federal Register, open for at least 30 days, detailing the project's scope, due diligence process, environmental compliance, and an economic impact analysis and engineering review . After the public comment period, the agency head must consider and respond to significant comments received. A critical provision requires a signed, written agreement with appropriate local government officials and the Governor of the State authorizing the activity. Additionally, the bill mandates that at least 30 days must elapse after the agency head submits a report to specific Congressional committees, including Homeland Security, Appropriations, and Judiciary committees in both chambers. This report must include a fully executed copy of the agreement with state and local officials. This ensures robust Congressional oversight and local community involvement in the decision-making process for new ICE facilities.
