Inspection criteria consisted of the following: • Review of permit conditions. • Evaluation of facility information and wastewater collection and lagoon system.000 NORTH CARCLINA � � North Carolina Department of Environmental Quality I Division of Water Resources Raleigh Regional Office 1 3800 Barrett Drive I Raleigh, North Carolina 27609 919.791.4200 DocuSign Envelope ID: 30CFBC66-DA22-44DF-8889-79CF72671 EE8 • Review of logbook, operation and maintenance plan (O&M), calibration records and Non -Discharge Monitoring Report (NDMR) and Non -Discharge Application Report (NDAR-1) . • On -site inspection of lagoon wastewater system and distribution components. Findings during the inspection were as follows: The system is composed of 125 service connections and 55 septic systems to the main 0.9 MG primary lagoon where solids separation occurs. A tie in at the center between the 7.8 MG stabilization/storage lagoon is connected to a submerged screened intake line which draws treated effluent into a .005 MG chlorine contact tank. The perimeter fencing surrounding the facility spray fields, storage lagoons and discharge pump/contact tank was secured. The freeboard level(s) in each pond were -35" respectively. lagoon freeboard levels are measured 3 times/week along with the required pH and Chlorine residual. The current operator in responsible charge (ORC) is Anthony Branch, and the designated backup is Williamm Lamm. The daily operations log and daily facility checkoff form(s) were complete. An O&M manual was not available at the time of inspection. A map of the collection system was not available at the time of inspection. A grease control program was not implemented or available at the time of inspection. Chlorine tablets were not evident in the chlorination tubes at the time of inspection. The correct supply of tablets were available on site. Additionally, the contact chlorine tank lids were not present/secured and the tank open to atmosphere. The Siemens Sitrans F M Mag 5000 influent magnetic flowmeter was last calibrated on July 27, 2023, by Delta Systems Environmental. Permit required lab analysis is conducted by Envirochem Laboratories. Effluent sample analysis was not available. The Annual Standard Soils fertility analysis is conducted by the North Carolina Department of Agriculture and Consumer Services (NCDA & CS) and samples were last collected in October 2022. Records were not available for review. The GW-59 reports were not available at the time of inspection. Envirochem collects the compliance samples and forwards the results to a compliance officer at Envirolink. The November 2023 samples were analyzed for volatile organic compounds (VOC) as required. Each of the four spray field zones (A, B, C, D) consist of a total of 130 spray heads individually isolated with a ball valve(s) and are operated for a total of 20 minutes each at a total flow of 180 gpm. Each zone is isolated with a manual valve to ensure even distribution in each zone. Field C and D had a total of 12 spray heads isolated due to the potential for ponding and runoff.

Because of this omission, it is possible that NDAR reports are inaccurate, and wastewater has been over -applied to the irrigation field. Requested Response: Within 30 days of the receipt of this letter, prepare a written plan providing a detailed description of how you will bring the facility into compliance with the permit. This plan should include a detailed schedule for completion for all the items listed below in addition to those highlighted in bold in the previous section. Items that can be completed prior to submittal of this plan should be completed and documented within the compliance plan. 1. Develop and implement a grease control program for the facility. This should include a plan for removal and proper disposal of the grease and other debris accumulated on the surface of the storage lagoon. 2. Develop and implement a program to regularly measure the accumulation of solids within the treatment/storage basin. If sediments are found to have reduced the storage capacity of the basin below that specified within the permit, develop a corrective action for removal and proper disposal of the solids. 3. Repair the broken and abandoned spray heads so that the application area as well as the hydraulic and nutrient loading rates match those in the permit. 4. Verify that there is no pooling or runoff of irrigated sewage. If pooling or runoff occurs, prepare a corrective action plan and submit this to the Division of Water Resources inspector. 5. Provide the Division of Water Resources inspector with the required plans and documents listed in the previous section, and make sure these are available on site.
