The Boston Harbor Islands Partnership is a non-profit partnership organization based in Boston, MA, whose purpose is "to coordinate the activities of the Federal, State, and local authorities and the private sector in the development and implementation of a general management plan" for the Boston Harbor Islands National Recreation Area. The Partnership was established by the United States Congress in 1996, as part of the law which designated the Boston Harbor Islands as a unit of the national parks system. Member organizations National Park Service (NPS) - Federal agency which provides a staff of park rangers who offer educational and interpretive services to visitors on Georges Island (for example, they lead tours of Fort Warren). NPS also provides a staff of rangers for the Downtown "Gateway Area" to the park, which includes the Boston Harbor Islands Pavilion and an additional booth on Long Wharf. NPS is not a land-owning member of the Partnership. Massachusetts Department of Conservation and Recreation (DCR) - State agency which provides a staff of park rangers at visitors' centers on both Georges Island and Spectacle Island. DCR rangers provide visitors with the same educational and interpretive services as NPS rangers. DCR is the primary land-owning member of the Partnership. United States Coast Guard (USCG) - Federal agency which owns and maintains the three lighthouses in the park area. Boston Light is located on Little Brewster Island. It was the first lighthouse to be built in what would become the United States. It also has the distinction of being the only non-automated lighthouse remaining in the United States (USCG personnel act as light keepers). Massachusetts Port Authority (MASSPORT) - State agency which operates Logan International Airport, as well as a variety of maritime industrial facilities (e.g., the Conley Container Terminal in South Boston, the Black Falcon Cruise Terminal, and the North Jetty). Massachusetts Water Resources Authority (MWRA) - State agency which owns and operates the Deer Island Waste Water Treatment Plant and the Nut Island Headworks. These facilities provide wastewater treatment for 43 communities, and have eliminated the discharge of sewage into the harbor. City of Boston - The City is a land-owning member of the Partnership; it owns Long Island, Moon Island, Rainsford Island and part of Spectacle Island. It also provides funding for environmental remediation projects on the various islands, for example the cleanup of asbestos contamination from Gallops Island (the island is therefore closed
