Normal maintenance operations at the Lake Townsend facility involving dredging of the process waste lagoon commenced in October 2017 and was completed on February 28th, 2018. The first monthly sample for February 2018 was taken on the 7th. This sample exceeded Daily Maximum limits for both Total Suspended Solids Concentration and Turbidity with values of 510 ppm and 118 NTU. The second sample for the month of February was collected on the 19th and exceeded the Daily Maximum Turbidity limit with a value of 65.5 NTU. The February 2018 monthly average for Total Suspended Solids was exceeded with an average value of 274.85 ppm. The multiple buoyed curtains deployed at the discharge end of the lagoon were inspected for integrity on the dates of the exceedances and found to be intact and functional. The contractor performing the dredging work was contacted each time there was an exceedance and verified that only normal maintenance operations were taking place. Visual inspections of the lagoon effluent were performed throughout the entire month and there were no incidents of foaming or reports of unusual aquatic activity. A second process waste lagoon is to be constructed at the Townsend Water Treatment Plant site beginning the summer of 2019. This will allow the City of Greensboro to perform normal maintenance dredging of a lagoon while it is isolated and out of service. We apologize for the quality of our effluent discharge during normal maintenance operations on an in-service basin and are taking corrective action that will improve the situation. 640 PO BOX 3136 • GREENSBORO NC 27402-3136 • WWW.GREENSBORO-NC.GOV • 336-373-CITY (2489) GREENSBORO NORTH CAROLINA Respectfully, Dell Harney City of Greensboro Water Supply Manager Desk 336-373-7900 Cell 336-430-6240 DH/mn Cc Jenny Graznak 640 PO BOX 3136 • GREENSBORO NC 27402-3136 • W W W.GREENSBORO-NC.GOV • 336-373-CITY (2489) SECTION SENDER: COMPLETE THIS ■ Complete Items 1, 2, and 3. r ■ Print your name and address on the reverse so that.we can return the card to you. ■ Attach this card to the back of the mailpiece, or on the front If spacepermits. 1.
