Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary)
Inspector Mikal Willmer, with the Asheville Regional Office, conducted a compliance evaluation
inspection of the TWSA #1 WWTP on January 8, 2018. 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.

ultrasonic flow meter at the effluent flume. TWSA is aware of the issue, but there is not an
easy solution. A stilling well or extension of the flume would allow for more accurate flow
measurements.
