Envirocon was recently awarded a second project at the Savannah River Nuclear Site for the remedial closure of the 488-1D Ash Basin located at the site in Aiken, South Carolina. Envirocon was selected from a field of five bidders based on a best value determination by proposal evaluators. This work will extend Envirocon’s presence onsite. Currently, the team is completing a consolidation and closure project in the 488-4D Ash Basin adjacent to the 1D site.
The 488-1D Basin has an area of approximately 40 acres. The project scope includes consolidation of 330,000 cubic yards of coal ash within the footprint of the 488-1D Ash Basin as well as coal fines and contaminated soil from a nearby coal pile runoff basin to an ash repository. The consolidated coal ash repository is approximately 20 acres in area. A cover system consisting of a six-inch soil base, geosynthetic clay liner (GCL), geosynthetic drainage layer (GDL,) and 20-inch compacted soil cover layer with four inches of top soil and sod will be installed over the ash repository to complete the closure.
This win adds to Envirocon’s resume of coal ash consolidation and basin closure and capping projects in recent years, increasing our ability to serve both private and public sector clients in the ever-growing CCR market.
