This inspection was conducted to determine whether the facility is being operated and maintained in compliance with NPDES Permit No. NC0039578. Stan Bryson, TWSA Wastewater Plant Operations Superintendent, was present for the inspection. Inspectors Bev Price and Tim Heim, with the ARO, assisted in the inspection. Overall the facility is being operated and maintained in compliance with the current NPDES Permit. No major findings were noted during the inspection. Inspectors recommended a few additional items at the time of the inspection. Float Checks: The facility primarily uses transducers as level alarms; however, floats are used as back-ups. ORC, Stan Bryson, states they routinely check float operation; however, it is not recorded. Recommend staff record any and all checks performed for future reference. Sampler Aliquots: Composite sampler is flow proportional. Currently the aliquot volume dispensed by the sampler is not checked. A minimum of a 100 mLs should be dispensed during each sample pull. Recommend checking this annually with a graduated cylinder and adjust as needed. Flow Measurement: Effluent flow is turbulent directly below the flow meter, which produces inaccurate measurements. The issue with the flume length and flow meter location was noted after the prefabricated flume was installed during upgrades. TWSA has been aware of this; however, it cannot be easily fixed. A stilling well would have to be installed and/or the length of flume would need to be increased to allow for a quiescent area for flow measurements. This should be addressed in the future plans for TWSA #1 to provide the facility and permitting unit with more accurate daily flows. NC0039578 17 (Cont.)
