This inspection was conducted to assess whether solids are being processed in accordance with non-discharge permit WQ0010059. Donnie Hawkins (ORC on-site), Ronnie Hendrix (Lab Supervisor on-site), Jeff Church (Operations Manager), Radford Thomas (Public Services Director for Town of Lenoir), and Jake Soots (Biosolids operator) were all present and assisted with the inspection. Residuals from the permitted facilities are stored in a sludge tank before being mixed with an emulsion polymer, belt pressed, thermally dried, and stored in a covered area outside (drains back to headworks) before being distributed. Users include farmers and the Public Works Department from the Town of Lenoir. Currently, based on staffing, residuals are processed 3 days/week, 12-24 hours/day. Approximately 164 dry tons of product were distributed in 2022, but a more accurate number will be calculated and provided on the annual report. After drying, the facility measures and tracks %TS daily which is typically >90%. Temperature is monitored on the belt press and double-checked with an instant-read laser thermometer gun. The temperature at the time of the inspection was approximately 200 degrees F. All paperwork was in order at the time of the inspection (O&M Plan, lab reports, current permit, Residuals Information Sheet, hauling records). Sampling results from February, October, and December 2022 were briefly reviewed to ensure samples are being analyzed for metals, nutrients, and pathogen and vector attraction reduction parameters. Non-hazardous characterization of residuals samples were analyzed in July 2021, meeting the once per permit cycle requirement.
