Remedial Design/Remedial Action Work Plan Wastebeds 1-8

This Work Plan was developed to address the Wastebeds 1 - 8 OU-1 selected remedy, as outlined in the U.S. Environmental Protection Agency's (USEPA) and NYSDEC's Record of Decision (ROD) dated December 2, 2014. The following Remedial Action Objectives (RAOs) have been established for the OU-1 remedy and are presented in the ROD:

  • Prevent ingestion/direct contact with soil/fill material/Solvay waste in surface and subsurface soil above
    levels that would result in unacceptable human exposure.
  • Prevent or minimize inhalation of or exposure to contaminants volatilizing from contaminated soil/fill
    material/Solvay waste that would result in unacceptable human exposure. In the event that buildings are
    constructed, mitigate impacts to public health resulting from soil vapor intrusion into those buildings, as may
    be warranted.
  • Prevent or minimize adverse ecological impacts to biota from ingestion/direct contact with soil/fill
    material/Solvay waste causing toxicity or impacts from bioaccumulation through the terrestrial food chain.
  • Prevent or minimize, the further migration of contaminants that would result in groundwater, sediment, or
    surface water contamination.

    Portions of Site groundwater are being addressed by elements of an ongoing Interim Remedial Measure ((IRM);
    O'Brien & Gere 2013). The long-term remedy for Site groundwater and Ditch A will be addressed as
    Wastebeds 1 - 8 Operable Unit 2 (OU-2).

The selected OU-1 remedy consists of the following cover components for the site:

  • One-foot thick vegetated soil cover
  • Two-foot thick vegetated soil cover
  • One-foot thick vegetated structural fill cover
  • Vegetation enhancement cover
