The site is proposed for industrial and commercial redevelopment following closure of the coal ash reservoirs and demolition of the idle power plant. Major elements of the ongoing project include the closure of four coal ash reservoirs covering roughly 200 acres, closure of two inactive landfill cells, remediation of several marginally stable above-grade ash disposal areas, and performance of a groundwater monitoring program to demonstrate compliance with applicable groundwater standards.
Activities Performed
KEY initially developed a plan for comprehensive ash management, including clean closure of the reservoir located closest to the nearby public water supply. Ash removed from the clean-closed reservoir will be placed into the remaining three reservoirs or removed from the site for beneficial reuse. The remaining reservoirs will be capped with low permeability clay to be obtained from upland portions of the site. The landfill cells will be capped in place, and the nearby above-grade ash disposal areas will be regraded as necessary and retrofitted with toe drains in excessively saturated areas. This overall approach has been conceptually approved by Ohio EPA.
KEY's activities include:
Reservoir Closure Design and Permitting, Dam Permit Compliance , Landfill Closure Design, Ash Disposal, Area Remedial Design, Closure Coordination with Plant Demolition Activities, NPDES and Groundwater Monitoring and Reporting, In situ groundwater remediation (sulfate reduction)
