USWAG Decommissioning Workshop, Crystal City, VA

December 12 - December 14

The Utility Solid Waste Activities Group (USWAG) is hosting its 2022 Decommissioning Workshop at the Hilton Crystal City at Washington National Airport, December 12-14.

SCS Engineers Vice President and Deep Well Injection Expert, Monte Markley, is presenting on Facilitating Site Development and Minimizing Post Closure Costs Using Deep Well Injection

Monte’s Abstract: Utilizing deep well injection to manage CCR leachate and other liquid residuals provides significant benefits as a facility is decommissioned. These benefits include facilitating site redevelopment by allowing leachate lagoon or evaporation basins to be decommissioned in the short term and utilizing the DIW for long term leachate disposal. The small foot print of a deep injection well (DIW) and the ability to continuously operate with minimal staffing allows conventional leachate management infrastructure real estate to be re-purposed. The ability to decommission leachate lagoons and other water treatment infrastructure (e.g. groundwater pump and treat systems) within 18-24 months after closure also allow the owner to avoid significant post closure care costs. Avoided costs included long term O&M, regulatory reporting and financial assurance. This presentation will outline the requirements to get a well permitted and operational at a facility, current examples of capital and opex costs and a case study of avoided costs.

The Decommissioning Workshop will cover myriad topics related to utility decommissioning, including:

  • Planning and Environmental Compliance Considerations
  • In-Place Retirement of Power Plants
  • End-of-Use Management of Wind Generation Assets
  • Solar Systems End of Life
  • Planning for Future Disposal of Renewable Generation Assets
  • Closure by Beneficial Reuse of Legacy Ash Storage Sites
  • Preparing for Abatement and Demolition
  • Deep Well Injection
  • and more!
