Keith Jones, Assistant Utility Plant Superintendent, Mark Solan, Utilities Plant Supervisor - Dryer Facility, Bonnie McKee, Utilities Plant Supervisor - Manson Meads Laboratory, and Devin Shields, Waste Residuals Technician, were present during the inspection. A review of records, treatment components, and system operations was completed. This inspection reflected compliance with the subject permit. The waste treatment system consists of a furnace with a rotating drum which produces a pelletized Class A material. Biosolids from Archie Elledge WWTP and Muddy Creek WWTP are dewatered using polymers and centrifuge presses before entering the pelletizer. Pellets that meet Class A requirements are stored in two silos before being transported by Soil Plus, LLC. Pellets are mostly land applied to agricultural fields. Pellets that do not meet Class A requirements are stored on a covered concrete pad and hauled to the landfill. A small percentage of pellets are retained and used in the pelletizer to make more pellets. Observations: • New personnel (Mark Solan and Devin Shields) have taken the positions of Bruce Casey and Diane Herndon who both retired recently. • The furnace facility is clean and well maintained. • The residual storage area is also well maintained. • No problem areas were noted during the inspection. The facility appears to be well managed. • The furnace and drum were not operating at the time of the inspection as they were being washed out. • Soil Plus purchases all pellets and distributes them as a third party. • Biosolids from Archie Elledge WWTP and Muddy Creek WWTP are stored in a single digestor before being dewatered.
