Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Consistant with last year's Compliance Inspection, this complex wastewater treatment facility appeared to be very well operated and maintained, and continues to maintain a very high standard of wastewater treatment. Please continue to keep up the good work! The following were noted during this inspection: 1) *1 Clarifier was down because of low flow to the VWVf'P (approximately 50% flow) and routine maintenance, 2) Nafion was temporily down, 3) the retention tank (emergency spill tank) was inspected in April 2009 and repairs performed on cracks, 4) in the future, the sludge holding tank will be repainted on the inside.
