REGAN Secretary LINDA CULPEPPER Interim Director 0 6 2011 Water Resources on Fernntting Subject: Compliance Inspection Lowell WWTP NPDES Permit No. NCO025861 Gaston County Dear Mr. Krouse: Enclosed is a copy of the Compliance Inspection report for the inspection conducted at the subject facility on November 27, 2017, by Ori Tuvia. Daniel Dougherty's cooperation during the site visit was much appreciated. Please advise the staff involved with this NPDES Permit by forwarding a copy of the enclosed report. The main area of concern observed during the inspection was that there was evidence of stormwater erosion around the influent pump station. Stormwater control measures (such as riprap) should be put along the side and entrance to the influent pump station to prevent erosion damage and to prevent stormwater from flowing into the pump station wet well. Additionally, the clarifier drive unit arm seemed to not remove all the surface scum. The report should be self-explanatory; however, should you have any questions concerning this report, please do not hesitate to contact Ori Tuvia at (704) 235-2190, or at ori.tuvia@ncdenr.gov.

Page# 8 ,a Water Resources Environmental Quality November 27, 2017 Mr. Robert Patterson, Water Resources Director City of Burlington PO Box 1358 Burlington, NC 27216-1358 Subject: Compliance Evaluation Inspection Report NPDES Permit NCO023868 East Burlington WWTP, Alamance County Dear Mr. Patterson: ROY COOPER Governor MICHAEL S. REGAN Secretary LINDA CULPEPPER Interim Director RECEIVED/DENR/DWR DEC 0 5 2017 Water Resources Permitting Section On November 21, 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. The presence and cooperation of Mr. Darrin Allred was greatly appreciated. This type of inspection consists of two basic parts: an on-site inspection of the facility and a review of facility files and self-monitoring data. Observations from each area of the inspection are summarized below. Site Review 1. Permit The current permit became effective on July 1, 2014 and expires on June 30, 2019. A copy of the current permit was available for review. Permitted components include a 4 million gallon aerated equalization basin, primary and secondary clarifiers, biological phosphorus reduction, sand filtration, and gas chlorination. 2. Facility Site Review The facility was as described in the permit. At the time of inspection, one secondary clarifier was down for routine maintenance. It was noted during the previous inspection that the plant planned to replace the gas chlorine disinfection system with liquid chlorine; however, Mr. Allred said that the details had not yet been finalized. The backup power generator is tested under load every month. An Authorization to Construct was recently issued for a dewatering press and related systems. Mr. Allred said that the installation was progressing well. --` 7',—Nathing Compares_-_.

Operation and Maintenance Darrin Allred is the current Operator in Responsible Charge, and Eric Davis and Kenneth Timson are backup ORCs. All operators are properly designated and hold the correct credentials. The operators use the Hach Water Information Management Systems (WIMS) database to track trends in the treatment process and integrate reporting and documentation, and the Hach JOB Cal system to track all preventative and repair work at the plant. Mr. Allred also keeps a paper notebook documenting his daily plant visitations. 4. Flow Measurement Effluent flow is measured with an ultrasonic secondary device set above a 2 foot Parshall flume. The calibration is checked quarterly by Instrument Specialists, Inc. 5. Effluent/Receiving Waters The effluent is discharged to the Haw River in the Cape Fear River Basin. Effluent appeared clear with no visible solids. In -stream monitoring requirements have been waived as long as the City of Burlington remains a member of the Upper Cape Fear River Basin Association. 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, daily operation sheets, maintenance reports, lab reports and Chain -of -Custody forms were available for review during the inspection. 7. Self -Monitoring Program A review of DMRs from September, 2016 through September, 2017 showed no violations, and a comparison of submitted DMR data with bench records showed no errors or concerns. 8. Laboratory All parameters are analyzed by the City of Burlington Wastewater Treatment Plant Laboratory under certification #188, except for headworks, toxicity and the effluent pollutant scan, which are analyzed by Meritech under certification #165. When a separate lab analyzes headworks samples, they also analyze all other samples collected that day. Operators of the plant analyze field parameters under the City of Burlington WWTP Lab's certification. Copies of all laboratory documentation are kept at the Burlington WWTP Lab. Effluent composite sampler is flow proportional. During the inspection, the thermometer inside the sampler read 0.5°C at the effluent and 2.5'C at the influent. Sampling and field parameter measurement procedures appeared acceptable. 9. Sludge Handling Disposal Lime stabilized residuals are land applied according to Division of Water Resources Permit WQ0000520. A portion of residuals stabilized by the Zimpro process are disposed of via transport to the landfill. Hauling records for each type of disposal were available at the time of inspection. 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, �6"/Sherri V.
