Box 1167 permitting Section Banner Elk, NC. 28604 SUBJECT: Compliance Evaluation Inspection Roaring River Chalets P NPDES Permit No. NC0032158 Watauga County Dear Mr. Brewer, On August 10, 2018, Kelli Park of this office met with Josh Cagle to perform a Compliance Evaluation Inspection on the Roaring River Chalets wastewater treatment system. Mr. Cagle was filling in for the operator in responsible charge (ORC); Paul Isenhour. This type of inspection consists of two basic parts: an in-office file review and an on-site inspection of the treatment facility. The attached Environmental Protection Agency inspection form notes the areas that were evaluated for this inspection. The findings and observations are outlined below: . I. Permit The NPDES permit became effective August 1, 2016, and expires on March 31, 2021. II. Self-Monitoring Program A review of the monthly discharge monitoring reports (DMR) for the period January 2017 through August 2018 showed that the facility was in compliance with all permit limits. - Grab samples are taken from an access point in the effluent pipe as it leaves the plant and before it reaches the receiving stream.

III. Records/Reports The permit and visitation log are located on site and show visitation times and plant conditions. Chain of custody forms are in good order. All required monitoring was performed per the frequencies specified in the NPDES permit. Miss Park noted no data transcription discrepancies from bench sheets to DMRs in her documentation review. Water Quality Labs maintains the documentation. IV. Flow Measurement - The instantaneous flow is measured by collecting effluent in a bucket for a minute of time. The effluent depth in the bucket is then measured, and the flow rate is manually calculated. V. Operations and Maintenance, The wastewater treatment plant appeared to be well maintained and operated. The ORC and backup ORC are sufficiently qualified to be running the plant. VI. Facility Site Review All components of the 0.005 million gallons per day facility appeared to be functioning properly. The aeration basin had a light brown color and a good earthy odor. All blowers were functioning properly and there were no dead spots. The dissolved oxygen is maintained around 2 milligrams per liter. The secondary clarifier looked clean and was discharging clear effluent. Effluent is disinfected by chlorine tablets, and then dechlorination tablets are used before the effluent leaves the plant. There is not a clear path to where the effluent pipe discharges into the receiving stream. There is rip rap along the side of the stream that the operators walk down. It is suggested that a clearer, safer, path is made so that there is easy access to the end of the pipe. We suggest clearing a small section of the rip rap and putting in steps. VII. Effluent/Receiving Waters 1 The effluent from the facility was clear the day of inspection. Effluent was being discharged into the Middle Fork offthe South Fork of the New River which is classified as a water supply, highly developed, rout stream in the New River watershed. VIII. Sludge Maintenance and Handling d e was reported to be um e� about once a year due to low flow in the plant. Triple Slug p P P T Plumbing pumps the sludge and ,the time, date, and how much was pumped is recorded into the operator log on site. It is a so documented at Water Quality Labs. I. 2 ) Roaring River Chalets,August 10,2018 IX. Conclusions The compliance evaluation inspection is satisfactory. Mr. Cagle maintains and operates the facility in a good manner. His efforts to comply with the permit are appreciated. If you have any questions regarding the inspection or this report, please contact Kelli Park or me at (336) 776-9800.
