In preparation for completing and the commissioning and startup activities for the WTP,we are requesting a modification of the County's NPDES Permit to allow a temporary discharge of treated water.This discharge is expected to be a temporary release of water that has been fully treated at the WTP but not yet approved by NC DEQ Public Water Supply for addition to the drinking water distribution system. The temporary discharge amount will be up to 6 mgd to allow discharge from the testing of each of the two 6-mgd treatment trains at the WTP.The discharge will occur at up to four blow-off valves on the finished water transmission main along New Salem Road-two at Lake Twitty,one at Mill Creek and one to an unnamed tributary of Richardson Creek(near Rilla Hamilton Road) if needed, as shown on the enclosed Figures 1-A and 1-B.Also enclosed are drawings showing the overall location of the WTP and proposed discharge locations (Sheet G-3),plan/profile drawings with the blow-off locations and receiving streams shown (Sheets C-36,C-42 and C-44),and a depiction of the blow-off valve (Detail F,Sheet CD-2). For a discharge flow range of 3 to 6 mgd,the blow-off discharge velocity at the planned three blow- offs is expected to be 2 to 4 feet per second.As shown on Detail F,each blow-off valve will have rip rap installed to a depth of 12 to 18 inches to prevent erosion. It is expected that the commission step requiring this temporary discharge will occur between May 2023 and July 2023,for a total of CDM Smith Ms. Emily Richards October 20, 2022 Page 2 approximately 6-8 weeks.The discharge will be dechlorinated as required to comply with the NPDES permit limits and/or other regulatory requirements for those receiving streams.The transmission main is planned to have interconnections with the existing Union County water distribution system.These interconnections will not be physically connected to the transmission main during this temporary discharge condition. Please review this request for a temporary modification to the County's NPDES Permit,and if you have any questions or require anything further,please do not hesitate to contact me at(704) 342- 4546 or at LapsleyJS@cdmsmith.com.
