Quick Facts
Location

Role

Completion Date
February 2025
Project Overview
The project consisted of removing CCR from the northern portions of the ash pond and consolidating the material into the southern portion of the pond for final engineered storage. CCR material was dredged from the main ash pond, then re-handled into a surge pond where it was precisely pumped to an ash thickening plant (ATP). The ash was dewatered via the ATP and pumped to the southern portions of the lake for final closure.
Phillips Contribution
Phillips was responsible for bulk dredging using cutter suction equipment in the main ash pond, re-handling the material in the surge pond, and redirecting the dredgeate to the ATP. The scope of work also included pond water management related to the overall pond water elevation and miscellaneous cleaning and removal of ash around the pond perimeter.
