Niagara Falls Storage Site (NFSS)

 landfill site / rubbish/garbage dump, nuclear waste storage

Created in February 1944 by the Manhattan Engineering District on the idled grounds of the former Lake Ontario Ordnance Works, the Niagara Falls Storage Site (NFSS) became a primary storage site for wastes and byproducts associated with Uranium ore refining being carried out in Tonawanda in support of the Manhattan Project.

Finding the largely unused and relatively remote site to be well-suited for storage of low-level radioactive materials and refinement waste products, the Manhattan Engineering District and Department of Energy continued to utilize their storage facilities until 1952 when all shipments to the site ceased. Following initial remediation and containment efforts as part of the DOE's departure from the site, the NFSS remained idle until 1982 when a full site, soil and facility remediation was carried out by the US Department of Energy.

Declared successful in 1986 following the consolidation of approximately 240,000 cubic yards of residues and wastes to a single containment area called the Interim Waste Containment Structure (IWCS) on the Western edge of the property, control of the NFSS was transferred to the US Army Corps of Engineers who continue to maintain and monitor the site.
