Maintenance buildings, facilities, equipment, and berthing areas used during Schuylkill River de-silting operations were situated on each of the dam properties. The facilities were built around 1950.
New Kernsville and Tamaqua buildings were demolished after being tested for hazardous materials, including asbestos. Demolished building materials were used to help preserve the Auburn building. Track mounted excavators with various claws and hammers were used to break apart and stockpile building and mooring cap materials including concrete, metal, and stone block. Explosives were not used as part of the project work. All demolition work was completed safely and in accordance with OSHA, state, and local regulations. Ferrous material not stockpiled, along with ancillary equipment, was removed from the site and disposed of at a properly licensed facility.
Work on the mooring caps at the Schuylkill River waters’ edge was completed after placement of a silt curtain in the water, preventing erosion and turbidity migration through any part of the water body. Approximately 230 linear feet of mooring cap was removed at New Kernsville and 90 linear feet of mooring cap were removed at Tamaqua, as measured along the water’s edge. The mooring cap was removed to just below the water line and as necessary to provide a 2:1 (H:V) bank slope. All areas were graded and reseeded to provide a stabilized surface.
Other erosion and sedimentation (E&S) control measures used during active demolition and up until earth stabilization had occurred included compost filter sock around stockpiled materials and disturbed areas, as well as, the silt curtain used during concrete mooring cap removal. CEG secured additional local permitting for demolition and or paving at each site location.
