Technical Support Document for Remediation Area E Shoreline- June 2014

Onondaga Lake

A capping and dredging offset has been chosen as the remedy for the the Shoreline E area of Onondaga Lake. This area is adjacent to the active railroad lines. The remedy will ensure that the shoreline and rail stability is not impacted. A detailed evaluation of potential alternatives was completed, resulting in selection of a revised approach that incorporates measures to improve habitat and promote natural recovery of sediments in this area. The low concentrations of contaminants in this area present minimal risks if not actively remediated. The reduced wind/wave energy along the shoreline following construction of a wave damper and planting of emergent wetland species will allow habitat recovery and natural recovery of the sediments in the shoreline E area. Details documenting the final design in this area will be provided in an addendum to Onondaga Lake Capping, Dredging, Habitat and Profundal Zone (SMU8) Final Design.
