NC0074306_Renewal (Application)_20230212
To whom it may concern, The Town of Forest City would like to request permission to renew its NPDES permit NC0074306. Enclosed you will find the Application Form 2A and required paperwork for renewal. Thank you for your consideration. Signed:�¢� RECEIVED FEB 21 2023 NCDEQ/DWF/NPDES Program Information All of the residuals produced from the Town of Forest City's Water Treatment plant are stored in the two (2), one million (1,000,000) gallon sludge storage lagoons. The residuals are produced from the treatment of raw water from the Second Broad River. The residuals come from two places during the treatment process. The first location during the treatment that the residuals are produced is from the sedimentation basins, from where the residuals are allowed to settle out. The return water left in the sedimentation basin is pumped to the sludge holding lagoons. The second place in the treatment process that produced residuals are from the filters. The filters are backwashed and the residuals from the backwash process are sent to the sludge holding lagoons. Also residuals are sent to the lagoons when a filter is rewashed during plant start-up. Once the residuals reach the sludge holding lagoons, they are stored until the lagoons are full enough to need a distribution event. Once it is determined that a distribution event is needed, the residuals are allowed to dry and they are removed from the lagoon with front end loadcrs and dump trucks. The residuals are given to local landowner's for use as a soil amendment. All of the residual are stored in the sludge holding lagoons along with any leachate or run off the may be present. All land owners that receive the residuals are given an information sheet that will explain all of the requirements and regulations for the material. This information sheet will'also highlight any nutrients that will be the limiting parameter for determining the residuals loading rate. In most cases, the limiting parameter for determining the loading rate will be nitrogen. Town of Forest City WTP PWSID # NCO181010 Sludge Lagoon Operation The Town of Forest City Water Treatment is an 8 MGD Conventional Water Treatment Plant with Flash Mixer, Flocculation, Sedimentation and Filtration. After filters are backwashed, water is disposed into two holding lagoons. After solids settle, supernatant is recycled back to the head works (flash mixer) of the plant. Once remaining solids are dewatered and dried through natural causes, solids are hauled from the lagoon by private contractor and properly disposed of through land application. The Sludge Lagoons have a total holding capacity of two million gallons. The recirculation pump located in the combined wet well is a 5 Horsepower Non -Clog Pump with an operating capacity of approximately 200 gallons per minute with a maximum daily flow of 288,000 gallons. The plant averaged a daily raw flow of 3.35 million gallons per day during January to December of 2022. The Town of Forest City policy for the Sludge Lagoon Operation requires recycle flow only during regular operation of the Water Treatment Plant to insure adequate dilution and mix with river water flow. The treatment process is monitored through hourly laboratory residual checks and visual inspection.
