FLY ASH FOR VIRGINIA POWER COMPANY

Chesterfield Station, Virginia

Virginia Power Company contracted with Southwind Construction Company to perform dredging of fly ash at three (3) separate locations with total ash removal ranging from 400,000 cubic yards at one site, up to one million cubic yards at their Chesterfield Station.

Southwind used an Ellicott® B-890 14-inch "Wheel-Dragon®" hydraulic dredge to efficiently (and cost effectively) remove the ash from one basin and transport the material via poly-pipeline to a storage basin. Silt curtains were utilized to control suspended solids and minimize turbidity at the discharge point into the James River. When levee conditions at the storage basin deteriorated due to heavy weather, SWC personnel monitored water levels and controlled the pressure on the levee by regulating the water discharge rate and by providing two (2) 10" pumps. Southwind completed the project successfully, on time, and under budget.
