Please ensure that future renewal applications are completed and submitted no later than six months prior to expiration to the division as required At the time of inspection, required logbook, maintenance, flow, calibration records and annual standard soil fertility analysis was available for review. Each lagoon freeboard level was clearly marked, identified, and recorded weekly, including discharge pump run hours and spray application rate(s). The treatment lagoon was secured and proper signage on the perimeter fencing. The two 3.55-acre spray field(s) were in good condition with consistent vegetative cover in each zone. The schedule of application to each of the spray fields is recorded each day to ensure even distribution. Spray nozzles are inspected for proper operation are the facility grounds were clean and structured. Each spray field/zone discharge nozzle(s), piping connections were inspected while on site. A section of the aluminum discharge line on the east side entrance of the spray field had become dislodged from a tree branch and will need to be repaired. The section was secured at the main line with a valve cap to ensure the area is receiving adequate pressure and an even spray -distribution pattern in each zone. 1.
