CCR Projects
Killen
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
