RECAN spavary 5, JAY ZIMMERMAN Dftvtor OCT 2 7 2017 Water Quality Permitting Section On October 5, 2017, Paul DiMatteo of the Division of Water Resources ("Division"), Winston-Salem Regional Office conducted a Compliance Evaluation Inspection of the above referenced wastewater treatment system. Matthew Smith, Operator in Responsible Charge (ORC), was present for the inspection. An inspection summary follows and an inspection report is attached for your records. Site Review 1. Permit The current permit became effective on July 1, 2016 and expires on April 30, 2021. A copy of the current permit was available for review. Permitted components include a septic tank, sand filter, UV disinfection and backup chlorination. 2. Facility Site Review The facility was as described in the permit. Access to the site is restricted by a chain link fence. Wastewater is dosed to the sand filter with a siphon mechanism, not a pump. A high water alarm is not present in the dosing tank. 3. Operation and Maintenance The operator or a properly designated backup visits the site as required. Visitation logs were current and available during the inspection. It was noted that our list of designated operators is not up to date. Please complete and submit the enclosed operator designation form so that our database can be updated. State of North Carolina I Environmental Quality I Water Resources 450 West Hanes Mill Road, Suite 300, Winston-Salem, NC 27105 Previous inspections noted that the sand bed appeared increasingly worse with time. While the bed's operation could not be evaluated during the inspection, it should be maintained to ensure proper operation.- Mr. Smith said that .the bed is occasionally raked by maintenance staff. 4. Flow Measurement Flow is estimated using data from the potable water meter. 5. Effluent/Receiving Waters The effluent is discharged into the Haw River in the Cape Fear River Basin. The outfall was visible from the bridge over the Haw River on Gerringer Mill Road. There was a slight discharge during the inspection. The stream did not appear to be negatively impacted. Documentation Review 6. Records/Reports Discharge Monitoring Reports (DMRs) and lab data are maintained according to the permit. DMRs include all permit parameters. Copies of DMRs, operator visitation logs, lab reports and Chain -of - Custody forms were available for review during the inspection. 7. Self -Monitoring Program A review of DMRs from January, 2016 through July, 2017 showed no violations, and a comparison of submitted DMR data and field records showed no errors or concerns. 8. Laboratory All parameters are analyzed by Research & Analytical Laboratories, Certification #34. ORC measures pH and temperature at the facility. All other samples are collected by the ORC and analyzed at the main laboratory. pH meter pre -run calibration and sampling procedures appeared acceptable. However, Mr. Smith said that a post analysis calibration check was not performed. Please refer to the enclosed technical assistance document, which states that "When performing analyses away from the certified laboratory's primary location, a post analysis calibration verification using the check standard buffer must be analyzed at the end of the run." Temperature is measured using the digital thermometer on the Dissolved Oxygen meter. It was .noted that the last calibration of this meter was performed on October 6, 2016. Mr. Smith said he would have the main laboratory perform the calibration within the coming days. 9. Sludge Handling Disposal Mr. Smith said that the septic tank is usually emptied twice per year. Records of the removal were available on site. The tank was pumped on 8/2017, 10/2016, 8/2016, and 2/2015 by Jenkins Waste Management.
