This inspection was conducted to determine whether the facility was being operated and maintained in compliance with Non-Discharge Permit WQ0004115. An NPDES inspection was conducted concurrently with this one for permit NC0087106. Danielle Hunter with RPB systems, and Craig Galloway with Champion Hills were present and assisted in the inspection. Overall, the facility appeared to be compliant. The inspection was performed in the off-season and therefore the irrigation system is not currently in use. Both wastewater treatment trains were in use during the inspection and flows were averaging 30,000 GPD. The following issues were noted and require attention: • There were excess floating solids in the clarifier which require consistent skimming and baffle maintenance. • The floats in the EQ basin are not connected to an alarm system. • The freeboard marker in the storage pond needs to be cleaned and placed upright. See the inspection report for NPDES Permit 0087106 for additional information regarding the floats and excess solids. The area surrounding the WWTP was cleared of pine trees a few years ago to reduce pine needle debris from entering the facility. This has helped with organic material entering the WWTP. There was no overgrowth of vegetation around the storage pond or NPDES discharge pipe. The ORC noted that duckweed dues grow on the storage pond in the summer months despite aeration. Generator: The propane gas generator is managed by Champion Hills staff. A contract firm maintains and services the generator. The generator self-exercises weekly, every Monday. The generator serves as backup power for the influent and effluent pump stations adjacent to the WWTP. Pump Stations: Aside from the influent and effluent pump stations adjacent to the WWTP, which are inspected by RPB Systems, the Champion Hills staff inspect the remaining 9 pump stations on site. Mr. Galloway indicated that all pump stations have alarms connected to telemetry, as well as backup power. The clubhouse has a grease trap that is cleaned monthly to prevent excess FOGs from entering the WWTP. Irrigation Pond: Mr. Galloway indicated that the pond is pumped dry every 2 years (last performed in 2022) to inspect the pond liner and perform any necessary cleaning/maintenance. The liner and the berms appeared free of any seeps or erosion. The freeboard level was approximately 2.5 feet during the inspection. The pond has adequate freeboard levels and primarily contains rainwater since the irrigation system is not in use during the winter. Irrigation Equipment Calibration: Irrigation equipment was last calibrated in 2018. As a reminder, irrigation equipment is required to be calibrated once per permit cycle. The next calibration will be due before the permit expires in 2024. Modification: Champion Hills is considering upgrading and/or moving the WWTP based on the age of the plant and potential increase in flow demands in the future. Should Champion Hills wish to increase the irrigation area and/or add acreage to the permit or change the WWTP, a permit modification would be required. Please keep the Asheville Regional Office and Non-Discharge Permitting Branch apprised of any planned changes to the system.
