22TDRRAD819 - FORMER COLD CREEK RANGER STATION SUPPLEMENTAL ASSESSMENT

The objective of this project is to implement an effective assessment strategy to confirm current site conditions, achieve adequate lateral and vertical delineation of the identified soil and groundwater contamination with respect to applicable Tier 1 or Tier 2 guidelines, and develop a comprehensive conceptual site model to guide future work at the site.
Further characterization is required at the following APECs:
 UST/Garage Area – Soil and groundwater PHC impacts require further delineation to the north, south, and west;
 Storage Shed Area – Surficial PHC soil impacts require further delineation and characterization;
Lagoon and Sediment Pond Area – Coliform exceedances resulting from sewage storage (surface water and groundwater) require further assessment to confirm decreasing trends; toluene soil, groundwater, and surface water exceedances require further characterization to determine origin (biogenic/petrogenic).
AEP is seeking to retain an environmental consultant to plan and execute appropriate next steps as described in the project objectives below and to provide recommendations to enable the department to take steps to ensure the protection of receptors through remediation and/or risk management.
