Scheduled Activities paragraph 2(a) Quarterly Reports Quarterly Nutrient Optimization Report and Quarterly SOC Report were submitted on October 30, 2023 Collection System Permit WQCS00056 Permit for Main Interceptor Replacement Project was Submitted on February 28, 2023, Sewer Extension Permit was issued on April 19, 2023. ARPA Sewer Rehabilitation Project Engineering Report was submitted on May 1, 2023, (not a formal activity), ER review is pending with NCDEQ however Survey work is complete and design is underway for this project. Permit application for a variance for low slope in some rehabilitation areas was submitted but was returned due to new NCDEQ policy. Currently working on encroachments and final design. Main Interceptor Project is included with scope for WWTP expansion and has been delayed based on delays in acquiring funding. Since funding has been secured with a letter of intent to fund from NCDEQ DWI, project is expected to go to bid soon. Town is continuing work to acquire easements for the project. All other Activities are scheduled for future quarters and are currently expected to be on schedule. NPDES Permit NC0026441 IUP Permits were issued to Mountaire Farms, Brookwood Farms, and the Siler City Water Treatment Plant on May 19, 2023. Mountaire Farms requested an adjudicatory hearing for their permit which was held on July 21. Mountaire is currently appealing the results of the hearing. Appeal is scheduled to be heard on February 15, 2024 Supplemental Aeration Equipment has been installed in the oxidation ditch basins. The installation was complete on May 26, 2023 with initial email notification on May 30 and a formal letter on June 29, 2023 notifying NCDEQ of completion. Additional Wastewater Flow Pursuant to Paragraph 4 Issuance of flow this quarter has been given to: Chatham Veterinary 500 GPD Dogwood Downs 600 GPD Last quarter Ingle Street Subdivision was initially given 1080 GPD @ 120 gallons but has been reduced to 675 GPD @ 75 gallons. Town of Siler Citv NPDES#NC0026441 WWTP Nutrient Removal Optimization Quarterly Report: 4th Quarter 2023 Introduction In accordance with NPDES Permit requirements this report is provided to document implementation of the optimization report and performance of the W WTP during the 4th quarter of 2023. The primary focus of this information is nutrient removal, however data on plant operations for other parameters are included as they influence the nutrient removal performance. Phosphorus (TP) removal is achieved with chemical precipitation and performance has been consistently good with effluent TP averaging less than 0.02 mg/1 during the 4th quarter 2023. Therefore, no further review of TP operation is included. Optimization Report Recommendations The optimization report was prepared in 2020 based on data from January to September of 2020. Operating parameters at the time are shown in Table 1 below. Table 1: Influent Wastewater during Optimization Study Parameter Daily Average during Optimization 2020 Daily Average for 4th Quarter 2023 Flow (mgd) 3.26 2.29 BOD (mg/1) 228 253 NH3 (mg/1) 19.5 26 TN (mg/I) 35.0 51 TKN (mg/L) 34.1 TSS (mg/1) 167 TP (mg/1) 3.34 2.3 The report recommends utilizing Simultaneous Nitrification/Denitrification (SNDN) to achieve nitrogen reduction. The recommended parameters include maintaining dissolved oxygen (DO) in the oxidation ditches between 0.8 to 1.2 mg/I and maintaining an FM ratio of 0.04 to 0.05 Ibs BOD/Lbs MLVSS with MLVSS between a concentration of 3,400 to 4,200 mg/l. Optimization Implementation During the 4th quarter of 2023 the overall performance of the Siler City WWTP has been very good with average effluent BOD of 0.22 mg/l, and Ammonia of 0.23 mg/I. The influent BOD has remained relatively
