A contractor working at the Duke Energy Roxboro plant struck a power line shortly before 9 a.m. Friday, knocking out power to about 3,400 customers in the area and shutting off power to a sump pump, causing a wastewater spill of about 12,500 gallons, according to Duke officials.
The incident was reported at 8:53 a.m. and by 10 a.m., the sump, which collects steam station process water used for such purposes as the cooling tower and facility wash water, started bypassing the treatment system and overflowed into a drainage canal that flows into Hyco Lake.
Duke said none of the wastewater that escaped had any coal combustion waste, nor did it have any contact with any coal ash.
Employees worked to stop the overflow and managed to complete that work by about 2 p.m. Shortly before 2:30, power was restored to the pump.
Other customers in the area were only out of power for about 30 minutes, Duke spokesman Bill Norton said Friday afternoon.
The company says it does not believe there was any impact to the public or the environment because of the spill.
Duke Energy reported the spill to The N.C. Department of Environmental Quality.
