The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit WQ0005790. Kenny Von Voigt, ORC, and Mark Moore, Wastewater Superintendent, were present during the inspection. The Town of Oak Island is permitted for a 400,000 gpd, Sequencing Batch Reactor wastewater treatment facility. Flow in the summer months averages 175,000 gpd and 65,000-80,000 gpd in the winter months. Non -discharge disposal consists of 25.5 acre dedicated reclaimed water utilization system consisting of Fields 6-14 at the William S. Smith Park, Fields 1-3 north of the plant and Fields 4, 4A, 5 and 5A at the plant site. Disposal also includes a 180,000 gpd high -rate infiltration basin and a conjunctive reclaimed water utilization system at the Oak Island Par 3 Golf Course across the street from the plant. The conjunctive site has never been used. In the last two years, the plant has had some treatment issues and violations for fecal coliform, ammonia, TSS and BOD. Technical assistance was requested from the Wilmington Regional Office in June of 2021 and through emails in May of 2022. Operators state that they believe there has been changes to the characteristics of the influent which is causing treatment issues. The Town has hired consultants to evaluate and determine the problems and help with solutions. Currently, additional operational data is being collected in order to make a determination of the exact problem. The Town continues to update the status of the evaluation and conditions of the plant to the Wilmington Regional Office. The facility is compliant with Non -Discharge Permit WQ0005790. Please review the comment sections of the inspection report for more details.

The DO was monitored with the facilities DO meter during the inspection, and the aeration basin DO meter reading was 0.50 mg/I. The ORC indicated that turning the air supply up to reach a higher DO will cause solids to float to the top in the downstream clarifier.

A review of GW-59 records since 2020 shows Nitrate limit violations for MW-2 and MW-8 and some TDS violations for MW-5. Staff indicated that the Nitrate violations could be from the fertilizing activities in that area and will investigate further. A review of NDMRs since 2021, show multiple limit vioaltions for Fecal Coliform, Ammonia, TSS and, more recently, BOD. The Town has hired consultants to evaluate and determine the issues related to these violations. End Use -Irrigation Are buffers adequate? Is the cover crop type specified in permit?
