Watts performed a New York State Department of Environmental Conservation (NYSDEC) site investigation, remedial alternatives investigation, remedial design, construction period services, and closeout for the remediation of two inactive landfill sites at the JN Adam Campus in Perrysburg, NY. Watts also acted as the liaison between the Client and the NYSDEC, United States Army Corps of Engineers (USACE), and State Historic Preservation Office (SHPO) for the duration of the project. All work was performed in accordance with NYSDEC site investigation and remediation procedures.
The JN Adam Campus is located on 522 acres of adjoining parcels. The Campus is heavily wooded with a number of institutional buildings that served as a former hospital and its associated support facilities. During the property's history (starting in 1909 as a tuberculosis sanitarium), refuse was reportedly disposed of in two on-site landfill areas. This property has been listed on the National Register of Historic Places since 1990.
Four remedial design alternatives were investigated by Watts including capping the landfills, consolidation and capping of the larger landfill, partial removal of the wastes, and full removal of the wastes. Watts prepared landfill remediation design documents, performed bid phase services, and performed the SEQR review and permitting including endangered species coordination, the creation of a SHPO Construction Protection Plan, SPDES design, and a Joint Application for Permit to realign an adjacent stream.
Watts performed bid phase and construction services for the removal of the 43,000 tons of waste and full closure/removal of both landfills. Watts also performed all NYSDEC closure coordination and prepared the landfill closure reports. NYSDEC accepted the landfill closure report without comment and full closure was achieved in November 2016.
