The other parameters are analyzed in-house. It was noted that one of the clarifiers has been taken offline for preventive maintenance. Synagro is responsible for pumping and hauling sludge, which is land applied under permit WQ0016247. A file review of the plant records indicated that all records are being kept as required. A comparison of the April, May and June 2008 DMRs indicated no discrepancies. It was noted that TKN and nitrite + nitrate was not reported on the DMRs. Please be reminded that any effluent data analyzed by a certified lab or person must be reported on the DMR. 12. Stormwater records were reviewed and found to be satisfactory. Both stormwater outfalls were observed during the inspection and no problems were noted. The SP3 was written and implemented in September 2007. Qualitative monitoring has been performed as required. The overall conditions of the Town of Siler City WWTP are compliant with Division standards.
