Compliance Evaluation Inspection Taylorville WWTP-NPDES #NC0026271 Alexander County, NC This letter addresses the deficientcies noted during our January 19th, 2007 inspection by Mr. Wes Bell. The August 2006 DMR has been ammended to reflect the proper Influent test results -(RECORD KEEPING). I also have placed an order for two new refrigerated compositers for Influent and Effluent programing. The old ones will be discarded upon arrival of the new units-(INFLUENT/EFFLUENT SAMPLING). PLA (sludge haulers) have set up today to remove excess solids to rectify our turbidity problems on side #2, which in turn will clear up our #2 CL2 train and the Final Effluent - (SECONDARY CLARIFIERS/EFFLUENT). (OPERATION & MAINTENANCE) -We have removed all sludge via vacuum truck to be placed back in the digester. The grass has been "limed" where 500 gallon spill occured. (BAR SCREENS) -Conveyor unit had slid out of position and had since been moved back into place to capture all debris from screener. Scum spillage has been shoveled into dumpster. (AERATION BASINS/AEROBIC DIGESTERS)-Land's Electric Company has been contracted to repair blower panels at all three locations. The one digester pump that is locked -up will be repaired. If there are any other items that need to be addressed, please contact me at (828)-632-5280. Thank you.
