Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) The following NPDES permit required parameters are analyzed by facility staff:.pH, Temperature, Dissolved Oxygen and Residual Chlorine under field parameter. certification #5350 All,other required parameters are analyzed by Meritech, Inc. Laboratory records were reviewed forthe months April 2005, July 2005 and December 2005 and compared to Discharge Monitoring Reports (DMRs). All records reviewed appeared to be accurate. A compliance evaluation for the period January 2005 to March 2006 did not reveal any violations. The facility did report during the inspection that for the month of April 2006 the following violations were noted: BOD-weekly (14.6 mg/L result--10.5 mg/L limit) & monthly (7.2 mg/L result--7.0 rrig/L limit, NH3 weekly (9.9 mg/L result--6.0 rng/L limit). The facility had an aerator down during this period when the violations occurred and they did contact FRO.
