RECAN keraary S. JAY ZIMMERMAN Dhvrtor On July 17, 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. Paul 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, 2017 and expires on April 30, 2022. A copy of the current permit was not available for review — one should be kept for inspection. Permitted components include an aeration basin, clarifiers, and chlorine disinfection. The facility is currently permitted to discharge up to an average of 0.5 mgd of domestic wastewater, non -contact cooling water and boiler blowdown. Average flow from October, 2015 to May, 2017 has been about 0.001 mgd. Due to the prolonged low flow, certain modifications were made, and some components have been allowed to deteriorate, as detailed below. Please note that, should the facility be changed such that the plant will receive nondomestic wastewater, part I, condition A(2) of the permit requires submission of a request for permit modification at least 180 days prior to such a change. Also note that, should the plant receive significantly more domestic wastewater, the deteriorated components may need to be repaired to achieve adequate treatment and compliance with discharge limitations. State of North Carolina I Environmental Quality I Water Resources 450 West Hanes Mill Road, Suite 300, Winston-Salem, NC 27105 2. Facility Site Review j The facility was as described in the permit. However, the system has been slightly modified. Currently, wastewater is discharge directly into the aeration basin, bypassing the mechanical bar screen. Water is contained in the aeration basin until there has been enough accumulation to warrant a discharge — recently, a discharge has occurred every 4 to 6 months. Once enough water has accumulated, the ORC inserts a small pump into the aeration basin and pumps to one of the clarifiers to allow settling of solids. Chlorine disinfection tablets are also inserted at this point. Water then flows through the chlorine contact chamber, is dechlorinated, and flows to the outfall. 3. Operation and Maintenance — Non-compliant The operator or a properly designated backup visits the site as required. Visitation logs were current and available during the inspection. The following maintenance issues were noted: a. Influent lift pumps and mechanical bar screens are not in use b. Only one (of two) clarifier is in use. This clarifier was noted to have significant vegetal growth, nonfunctional skimmer, and corrosion in the central ring. Part II, Section C.2 of your permit states that "the Permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to achieve compliance with the conditions of this permit." Although the plant appeared to be properly treating what waste it receives at the time of inspection, it should be noted that allowing components of the system to deteriorate may affect performance in the future, especially when flow is increased. The level of deterioration of this system has resulted in the rating of non-compliant and the subject Notice of Deficiency. 4. Flow Measurement Flow is calculated manually by multiplying the portable pump's run time with its flow rate. 5. Effluent/Receiving Waters The effluent is discharged into the Dan River. The outfall was accessible during the inspection. A trickle was observed to be discharging at the time of inspection. The effluent appeared clear with no impacted to the receiving stream. Documentation Review i 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 May, 2016 through May, 2017 showed no violations, and a comparison of submitted DMR data and field records showed no errors or concerns. i State of North Carohna I Environmental Quality I Water Resources 450 West Hanes Mill Road, - Suite 300, Winston-Salem, NC 27105 8. Laboratory Field parameters are measured by the ORC under certification # 5169 (Smith Industries). All ._effluent samples are taken from the aerobic digester. All other- parameters are measured by Pace Analytical under certification # 633. Chain -of -custody forms were complete and available for all parameters measured off site. Records for parameters measured on-site were complete. 9. Sludge Handling Disposal Sludge is removed from the plant as needed. Remedial actions should be taken to correct the deficiencies noted above and to prevent their occurrence in the future. Please be advised that, under state law, a civil penalty of up to $25,000 per violation may be assessed against any person who violates or fails to act in accordance with the terms, conditions or requirements of a permit (refer to Permit Conditions, Part II, Section B.1(f)). If you should have any questions, please do not hesitate to contact Paul DiMatteo at (336) 776-9691 or our office at (336) 776-9800. Sincerely, Fo'/Sherri V.
