VertiCell™ – Retrofit Construction Method for Coal Ash Basins
Since January 2022, the EPA has issued several decisions related to coal ash, signaling it is finally taking the 2015 rules seriously. Among other actions, the EPA has ordered companies to stop placing ash in unlined ponds since keeping coal ash in unlined storage has long been the threat to drinking water.
VertiCell™ construction method of a segmented bunker style retrofit system can be completed safer, better, and cheaper than a typical traditional methods of coal ash basin retrofits.
VertiCell™ consolidates, compacts the ash by utilizing the vertical airspace created over a limited area. These segmented bunker style cells are quickly filled, capped, and rendered inert at a much faster pace than traditional methods. Here at EnCAP-IT we refer to this process as Progressive Filling and Progressive Capping.
VertiCell™ Progressive Filling
Limits “Double Handling”
Greater Inventory Control
VertiCell™ Progressive Capping
Outside slopes capped using a “shingle” method
Outside slopes form bi-directional hydrostatic barriers
Individual bunkers capped at a rapid pace
Creation of V-Notch bunkers allows greater stability
Segment approach provides stability relief on outside slopes
VertiCell™ Method = Cost Control
Minimizes Off-Site Transportation Costs
Optimizes the use of On-Site Property
Closure timeframe is reduced
Efficient placement of “off spec”, less desirable excavated coal ash
Final (Smaller) footprint = lower Post-Closure care/financial assurance
