The assistance and cooperation of Shelby Cheek, Operator in Responsible Charge (ORC), was greatly appreciated. Inspection findings are detailed below and in the accompanying checklist. Records Review: Operational records were reviewed and found to be complete, current, and compliant. This includes operator visitation logs, operations logs, maintenance logs, and other pertinent records that the operators provided during the inspection. Records are kept for at least 3 years. Analytical records are complete, current, and compliant. The permittee uses Water Tech labs and conducts field parameter analyses in house. Chains of custody, lab reports, etc, were all available for review. All analytical records are kept for at least 5 years. No discrepancies in reporting lab results were noted. The current permit is maintained onsite. Plant Inspection: The influent pump station and equalization basin are fully operational and no issues were noted. The bar screen is operational and in good condition. The aeration basins (AB) appear to be in good condition and the mixed liquor appears healthy. The ABs use diffused aeration and they all appear operational and there are no deadspots in the basins. The clarifiers also appear in good condition and operating properly. The weirs are level and no short circuiting was noticed in the clarifiers. The plant uses chlorine tablets for disinfection and dechlorination tablets for dechlorination. No issues were noted with the chlorinator or dechlorinator. The effluent flow meter is used for reporting and it was just recently calibrated. It reports both a constant flow rate as well as the total flow. The effluent appeared excellent. It was very clear and there is no odor. Fish were seen in the immediate area of the outfall. No permit deficiencies or violations were noted during the inspection.
