CCR Projects

Killen

Our client is redeveloping a 2,100-acre site that housed a 618 megawatt dual fuel electric power plant. The site is located near Manchester, Ohio on the Ohio River.

Major elements of the project includes 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, which has been assigned a High Hazard Potential Classification by the Ohio DNR. Closure of these Coal Combustion Residuals (CCR) units is being performed in accordance with the USEPA’s April 2015 CCR Regulations as well as Ohio EPA and Ohio DNR requirements. Major elements of the project include the closure of the CCR units, beneficial reuse of gypsum and two (2) groundwater monitoring programs.

Activities Performed
KEY initiated redevelopment efforts by preparing a scope of work for all environmental activities site-wide. These activities include the development and implementation of an Action Plan to address all 2100 acres, groundwater monitoring programs and preparation of Permits-to-Install (PTIs) for closure of the CCR units.
KEY prepared a closure plan concept for the Fly Ash Pond that will involve a combination of clean closure and capping in place, and which will use portions of the impounding embankment as a borrow source for the clay and vegetative layer components of the soil cap.

KEY’s activities include:
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

Plant Demolition and Closure
KEY is currently providing engineering support to work through plant demolition and closure of the coal combustion residuals (CCRs) units. The Client is pursuing clean closure of the majority of the units and closure in place of one 230-acre ash pond. KEY is proceeding under the Federal CCR Rules, while concurrently satisfying the Ohio Environmental Protection Agency (OEPA) requirements.

Our scope includes:
Construction engineering support, Borrow materials evaluations, preparation of closure plans and Permit-to-Install applications, Groundwater monitoring, Permitting support, Material management evaluations and technical support, Coordination with the OEPA and the Ohio Department of Natural Resources, Groundwater program refinement, Optimization of the closure designs
