CCR Projects


Project Description

The redevelopment of Killen, a 2,100-acre site that housed a 618 megawatt dual fuel electric power plant near Manchester, Ohio includes the closure of CCR units, beneficial reuse of gypsum, and two groundwater monitoring programs. Major elements of the project included developing closure plans for two FGD sludge (gypsum) Collection Basins, a Coal Yard and Coal Yard Runoff Pond, and a 225-acre, 70-foot deep Fly Ash Pond. The Pond has been assigned a High Hazard Potential Classification by the Ohio DNR. Closure of these CCR units was performed in accordance with the Federal CCR Rule as well as Ohio EPA and Ohio DNR requirements.

Activities Performed

KEY initiated redevelopment efforts by preparing a scope of work for all environmental activities site-wide. These activities included the development and implementation of an Action Plan to address all 2,100 acres, groundwater monitoring programs, and preparation of Permits-to-Install (PTIs) for closure of the CCR units. KEY’s activities included:

  • Closure Design (PTI) for the Fly Ash Pond

  • Closure Designs (PTIs) for the Collection Basins, Coal Yard and Coal Yard Runoff Pond

  • Dam Permit Compliance

  • Closure Coordination with Plant Demolition/Activities

  • Groundwater Monitoring and Reporting

  • Groundwater Fate and Transport Modeling

  • Evaluation and Selection of Groundwater Remedial Alternatives
