CCR Projects

Hollow Rock

The Site is a 940 acre Class III Residual Solid Waste (RSW) landfill located in Jefferson County, Ohio. The residual waste placed in the landfill consists of coal combustion residuals (CCRs) and gypsum resulting primarily from electric generation. The overall permitted limit of waste has been divided into development phases where four cells have reached the maximum elevation and have received intermediate cover. Currently, the Site is receiving waste in the last constructed cell via off-road dump truck.

Leachate is managed via a collection system and collected in the Sites leachate storage lagoons located adjacent to the disposal pad. The leachate in the lagoons is pumped utilizing an overhead loadout system into tanker trucks for transport and hauled offsite for use as recycled make-up water in a wet flue gas desulfurization system.

KEY completed a Phase I Environmental Site Assessment according to ASTM E1527-21 and determined Site Recognized Environmental Conditions (RECs), Historical Recognized Environmental Conditions (HRECs), Controlled Recognized Environmental Conditions (CRECs), and Observations.

During project transition activities KEY assisted with site permit transfers such as Title V air permit, NPDES permit, and annual site operating license. KEY has assisted with the update of Site specific plans such as the Stormwater Pollution Prevention Plan (SWPPP) and Spill Prevention, Control, and Countermeasure (SPCC) Plan.

KEY developed a compliance schedule including sampling dates, report submittals, and inspections in accordance with site permits, plans, and Federal CCR regulations.
