Our team worked with Platte River to address the entire scope of CCR compliance, including identifying water redirection options, alternative wastewater solutions, ash bunker location options and potential landfill impacts on the more than 4,500- acre site.
Rawhide was previously designed with a system where bottom ash was collected in the base of the boiler and then hydraulically sluiced through a piping system to one of two bottom ash transfer ponds. Sluice water was circulated back to the plant and reused. When a bottom ash pond was full, it was isolated to allow evaporation, then solids were dredged and hauled to an on-site ash monofill. To meet the CCR rule’s stipulations for ash transport water and groundwater monitoring for ponds, Platte River decided to install a mechanical ash removal system and close its existing bottom ash ponds.
