Box 1167 REDENEDINCDE(�D Banner Elk,NC 28604-1167 APR 13 2016 SUBJECT: Compliance Evaluation Inspection Water Quality ion Yonahlossee WWTP Permitting NPDES Permit#NCO032212 Watauga County Dear Mr. Brewer: A Compliance Evaluation Inspection was performed on the facility by George Smith, along with April Norton on March 23, 2016.Mr. Brandon Hughes, ORC, Grade II; Mr. Jadd Brewer,Back-up ORC, Grade III; were present for the inspection. The inspection is comprised of an overall evaluation of the facilities equipment, capability to meet effluent limits, and compliance with the NPDES permit. Permit Your NPDES permit became effective February 1, 2013 and expires September 30, 2017.•This office received a copy of the letter dated February 17, 2016 requesting the facility be changed from composite to grab sampling. The permitted flow for this facility will need to be changed from 0.04 MGD to 0.03 MGD. Records &Reports The operator and plant log are printed on a form showing visitation times and plant conditions.The log will be examined more thoroughly during the next year inspection for visitation times,observations,and process control. The chain of custody forms and calibrations records are in good order. Field test calibrations were documented for pH,Temperature, and Dissolved Oxygen. Facility Site Review The treatment plant is not open to the environment.The building has fallen down.The plant can be visually operated and maintained in a safe manner. The left-side of the treatment unit is not operated. The equalization basin is located in a separate building.The pumps are working. This treatment unit is still located in a building with poor lighting. The aeration basin diffusers are working. The blower motors were operational. A 1-inch manual barscreen is manually cleaned. It protects the plant.

The blanket height in the 10-foot deep clarifier is not generally measured. Settleability is used to judge process control conditions. The Trojan 200 UV disinfection unit is working. The indicator lights are on. Flow Measurement The recording flow measuring device was calibrated by B.W.Allen on October 8,2015. Laboratory Water Quality Lab, Inc. 4544 is certified, and performed the following field tests: Dissolved Oxygen, pH, and Temperature. The pH meter is calibrated with a two-point buffer of 4& 10, and check with a pH 7 buffer. A calibration log was kept for pH and dissolved oxygen, and total residual chlorine. Temperature is traceable to NIST. Effluent/Receiving Waters The effluent, which discharges to Lance Creek, Class C; Trout waters, was clear, no color, no solids, no odor.The stream does not appear to be impacted. Operations &Maintenance The Class II facility was maintained by the following contingent:Mr.Brandon Hughes,ORC, Grade II and Mr. Jadd Brewer,Back-up ORC, Grade III. Self-Monitoring Program A time composite sample is performed at 100 mL/hr. The NPDES flow proportional requirement will not be examined at this time. The NPDES Unit is reviewing the request to change the permit from flow proportional sample to grab sample. A review of the monthly self-monitoring reports from August 2015 through January 2016 did not show any limit violations. The compliance evaluation inspection is satisfactory.Mr. Hughes is doing a very good job at operating the facility. If you have any questions, please contact George Smith or me at(336)776-9800.
