Ron Boone of the Winston Salem Regional Office (WSRO) of the North Carolina Division of Water
Resources (DWR or the Division) conducted a compliance evaluation inspection of the 1-77 Rest Area Yadkin County
Wastewater Treatment Plant on March 1, 2016. The assistance and cooperation of Michelle Anderson, Operator in
Responsible Charge (ORC), was greatly appreciated. An inspection report is attached for your records and the
inspection findings are summarized below.
The 1-77 Rest Area Yadkin County Wastewater Treatment Plant is located on 1-77 North at approximate
coordinates 36.1052980,-80.811589e, in Yadkin County, North Carolina. The DOT is authorized to operate this 0.018
million -gallon -per -day (MGD) wastewater treatment plant, which consists of an aerated flow equalization tank, flow
splitter box, parallel extended aeration basins, parallel clarifiers, aerated sludge holding tanks, chlorine contact
chamber with injection type chlorination, tablet -type dechlorination with step aeration, and a flow meter, and discharge
treated effluent from outfall 001 of said treatment works, which is located approximately 80 feet to the east of the plant
at approximate coordinates 36.105949e,-80.811305e, into Rocky Branch, which is currently classified as Class WS-III
waters and is located in the Yadkin Pee -Dee River Basin.
