(Rebecca Blackwell | AP)MIAMI — A lawsuit brought by environmental groups and the Miccosukee tribe challenging construction and operations of an immigration detention center in the Florida Everglades wrapped up Wednesday with several key questions unanswered. Federal judge halts construction at Florida’s ‘Alligator Alcatraz’ The 14-day stoppage comes as a federal judge considers whether additional construction of the immigration detention facility in south Florida’s Everglades is detrimental to the environment. The three plaintiffs say the rushed construction without public input or an environmental impact assessment violate federal law and they’re asking the judge to shut it down. At issue is NEPA — the National Environmental Policy Act — which requires federal agencies to consider alternatives, engage the public and assess the environmental impact before proceeding with a project.
