Redevelopment at the Site

The Syosset Landfill Superfund site occupies about 38 acres in the Town of Oyster Bay, New York (the Town). The landfill operated from 1933 until 1975, accepting commercial, industrial, residential, demolition, agricultural, sludge wastes and ash wastes. A site inspection in 1982 found that former landfill practices had contaminated site soil and groundwater and had created the potential for exposure to landfill gas. EPA added the site to the Superfund program’s

National Priorities List (NPL) in 1983. Cleanup activities included installing a permanent ventilation trench to prevent potential gas vapor migration from the landfill to neighboring residences and an elementary school, as well as a cap to contain waste buried at the site. After EPA completed cleanup and determined that the site does not pose a risk to human health, EPA deleted the site from the NPL in 2005. The Town of Oyster Bay returned the site to productive use. The site now includes a salt storage facility, an equipment storage facility and a vehicle parking area for municipal sanitation trucks. In 2009, the Town received American Recovery and Reinvestment Act (ARRA) funds through the U.S. Department of Energy Clean Cities Alternative Fuel and Advanced Technology Vehicles Pilot Program. The funds helped the Town build a compressed natural gas (CNG) fueling station at the site. The station allows the Town to fuel 44 sanitation trucks with CNG. The Town completed the fueling facility in 2011. Recently, EPA began discussions with a local development group about a multi-use development plan at the Syosset Landfill site. The conceptual plan includes reusing the landfill for passive and active recreational activities. EPA will continue to work with the developer and ensure continued protection of human health and the environment throughout the reuse process.
