Impoundment Management

Coal Ash Services provides turnkey, CCP regulation-compliant ash impoundment management services. We can dredge active ash ponds, dewater the material, and provide options for temporary ash storage or disposal. Our on staff Professional Engineers and certified water treatment operators guide operations to ensure compliance with the CCP rule and your facility’s NPDES permit.

Are you transitioning your ash impoundment to an overfill facility or alternate ash handling process?

Coal Ash Services can accept plant ash slurry discharge directly into a dewatering process, providing ash dewatering and storage, during the transition period. We can dredge directly to geotextile tubes in your existing CCP landfill, and have extensive experience doing this. We can provide water treatment operations assistance and certified operators to ensure the landfill leachate is properly treated and discharged in compliance with NPDES permit requirements.

Is your ash impoundment full to capacity?

We can clean impoundments to ensure compliance with run-on/run-off controls and hydraulic capacity requirements, providing dredging, dewatering and disposal services via a single, experienced contractor. We will dredge your ash pond while it remains in active service, with little disruption to plant operations. Coal Ash Services uses best management practices to protect pond liners from damage during the dredging process, and prevent TSS spikes or permit limit exceedances in the pond discharge.
