 As a result of this pressure, in May 2003 the Navy withdrew from Vieques, and much of the island was designated a National Wildlife Refuge under the control of the United States Fish and Wildlife Service.The island was also placed on the National Priorities List (NPL), the list of hazardous waste sites in the United States eligible for long-term remedial action (cleanup) financed by the federal Superfund program.Closure of Roosevelt Roads Naval Station followed in 2004, and prior to Hurricane Maria the Roosevelt Roads Naval Station was reopened.
