Sam Pegram, ORC, was present during the inspection. The inspection consisted of an on -site inspection of the treatment facilities and a review of facility files and self -monitoring data. The following is a summary of findings during the inspection: A. Facility records (daily logs and maintenance records) are well organized and current. A review of self -monitoring data showed that laboratory data correctly correlates with data submitted on the monthly Discharge Monitoring Reports. Be sure to include time of day for meter calibrations. B. Calibration of the flow meter was checked on July 18, 2014. C. Sludge in the plant appeared old, and there were excessive solids in the clarifier. Mr. Pegram said a pump had been replaced in October 2014, but pulled back out in March 2015. A new pump is available, but staffing issues have prevented him from being able to replace the pump yet. He says this would be done within a week, and believes this will correct the hydraulic overloading of the plant. Please refer to the attached report for more inspection details. Should you have any questions please contact Jenifer Carter in our Winston-Salem Regional Office at (336) 776-9691. Enclosure cc: DWR central files WSRO files Sincerely, ";.`� W.

Skvarla, III Secretary On July 16, 2014, Ms. Jenifer Carter of the Winston-Salem Regional Office conducted a Compliance Evaluation Inspection at Salem Glen and Spring Creek Subdivision's wastewater treatment facilities. Sam Pegram, Back-up ORC, was present during the inspections. Ryan Smith was also present during the inspection at Spring Creek. The inspections consisted of an on -site inspection of the treatment facilities and a review of facility files and self -monitoring data. The following is a summary of findings during the inspection: A. Facility records (daily logs and maintenance records) are well organized and current. A review of self -monitoring data showed that laboratory data correctly correlates with data submitted on the monthly Discharge Monitoring Reports. B. The flow meters were calibrated in July 2014 and April 2014 respectively. C. The sampler tubing at Spring Creek's needed to be replaced. D. There were floating solids/ pin floc in the clarifiers of both plants. Mr. Pegram did not have a sludge judge on hand to measure the sludge blanket levels at Salem Glen, though he says he uses settleability to determine wasting needs. Mr. Smith measured the sludge blanket level at Spring Creek, which was at an acceptable level. The overflow at both plants was clear. E. Mr. Pegram and Mr. Smith said they check meter calibrations each morning that meters are used for compliance monitoring. Make sure that calibrations and calibration checks are recorded as per laboratory certification requirements. Please refer to the attached reports for more inspection details.

Sam Pegram, Back-up ORC, was present during the inspections. The inspections consisted of an on -site inspection of the treatment facilities and a review of facility files and self -monitoring data. A review of the submitted self -monitoring data revealed no permit limits violations at either facility. The following is a summary of findings during the inspection, with deficiencies noted in bold print. A) Copies of the permits, maintenance records and self -monitoring data were readily available. There were some transcription errors, especially with time on site and temperature data. Compliance status was not affected. B) The flow meters were calibrated in July 2013 C) The thermometer at Spring Creek's effluent sampler registered 7eC, and the thermometer had not been checked against an NIST thermometer since 2008. Please have the thermometer checked annually and adjust the temperature of the refrigerated sampler as necessary. D) There were floating solids/pin floc in the clarifiers of both plants, especially at Salem Glen, though the effluent leaving the clarifiers was clear. Mr. Pegram had not checked the sludge blanket levels since he started operating these plants recently (due to the ORC being on medical leave). He promised to do so as soon as possible and take action as warranted. E) Mr. Pegram admitted to calibrating his meters only once weekly. Dieters should be calibrated within 24-hours of use and the calibration checked at the end of each day, when used for compliance purposes. Please refer to the attached reports for more inspection details. Should you have any questions please contact Jenifer Carter in our Winston-Salem Regional Office at (336) 771-4957. Sincerely, W.

Mr. R. Mike Barker, ORC, was present during the inspections. The inspections consisted of an on -site inspection of the treatment facilities and a review of facility files and self -monitoring data. A review of the submitted self -monitoring data for the period of September 2009 through August 2010 revealed no permit limits violations at either facility. With respect to the administrative portion of the facility's self -monitoring programs, no deficiencies were noted. The following is a summary of findings during the inspection. A) Records were well organized and current for both facilities B) While there is considerable rust on the exterior of the plants, the interiors seem to be in relatively okay condition. C) Copies of the permits, maintenance records and self -monitoring data were readily available. D) Thermometers have been placed in the sampling units since the last inspection. E) The sludge blank in the secondary clarifier at Spring Creek was 8 feet deep. Mr. Barker noted that some wasting was in order. The sludge blanket was not measured at Salem Glen during the inspection, though there were similar amounts of floating solids at both plants. F) The effluent flowing from both plants was clear. Overall, both plants appear to be sufficiently maintained and operated. Should you have any questions please contact Jenifer Carter in our Winston-Salem Regional Office at (336) 771-4957.

This is in violation of Part Il, condition D(2) of the NPDES permit, as well as 15A NCAC 213 .506(a), which requires the submittal of Discharge Monitoring Reports no later than the last calendar day following the reporting period. Failure to submit reports as required will subject the violator to the assessment of a civil penalty of up to $25,000 per violation. You will be considered noncompliant with the self -monitoring requirements of your NPDES permit until the report has been submitted. To prevent further action, please submit said report within fifteen (15) days of receipt of this notice. Additionally, this letter provides notice that this office will recommend the assessment of civil penalties if future reports are not received within the required time frame during the next twelve (12) reporting months. The Division must take these steps because timely submittal of discharge monitoring reports is essential to the efficient operation of our water quality programs. We appreciate your assistance in this matter. If you have any questions about this letter or discharge monitoring reports, please contact me at 919-807-6388.

Deot of ENR JAN 16 2009 &nston•,.: i ;- I Regional office Subject: Draft NPDES Permit NCO083925 Salem Glen Subdivision WTP Davidson County Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft very carefully to ensure thorough understanding of the conditions and requirements it contains. The following procedure has been recently implemented by DWO: Total residual chlorine (TRC) compliance level changed to 50ug/L. Effective March 1, 2008, the Division received EPA approval to allow 50 ug/L TRC compliance level. This change is due to analytical difficulties with TRC measurements. Facilities will be still be required to report actual results on their monthly discharge monitoring report (DMR) submittals, but for compliance purposes, all TRC values below 50 ug/L will be treated as zero. A footnote regarding this change has been added to the effluent limitations page(s) in the draft permit. Regarding the receiving stream of the WWTP discharge, this section of the Yadkin is listed as an impaired stream on North Carolina's 303(d) list. This means that this river section does not meet all water quality standards. The Division is working hard toward the improvement of water quality in this section of the Yadkin River. If the current changes to permits discharging to this section of the Yadkin River do not result in improved water quality, removal of discharges to this section of the Yadkin River may be necessary for the health of the river. If noncompliance with your permit's effluent limits is shown to be a direct cause of stream degradation, the Division will recommend removal of your facility's discharge. You should be continually evaluating all wastewater disposal alternatives and pursue the most environmentally sound alternative of the reasonably cost effective alternatives to surface water discharge. Such an evaluation may help you find an alternative to surface water discharge that is more appropriate for your facility. Concurrent with this transmittal, the Division will solicit public comment on this draft as required by the EPA by publishing a notice in newspapers having circulation in the general Davidson County area. Following the 30-day public comment period, the Division will review all pertinent comments and take appropriate action prior to issuing a final NPDES permit. Should you wish to correct errors or provide comments regarding this draft please contact the DEN / DWO / NPDES Program no later than 30 days after receiving this document. If you have questions concerning the draft permit for your facility, please contact me by e-mail (bob.guerra@ncmail.net) or at (919) 807-6387.

Easley, Governor O�O� W AT �RQG Mr. Michael Myers Aqua North Carolina, Inc. 202 Mackenan Avenue Cary, NC 27511 SUBJECT: Compliance Evaluation Inspection Salem Glen Subdivision NPDES Permit No. NCO083925 Davidson County Dear Mr. Myers: William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Coleen H. Sullins, Director Division of Water Quality Ocfob,er 21; �2003- Jenifer Carter of the Winston-Salem Regional Office (WSRO) performed a Compliance Evaluation Inspection at Salem Glen Subdivision's Wastewater Treatment system on October 8, 2008. Mr. Marc Stokes, (WSRO Technical Assistance), Mr. Tony Parker (Aqua's Area Manager), Mr. Samuel Pegram (ORC), and Mr. Robert `Mike' Barker (back-up ORC), were also present during the inspection. The inspection consisted of two parts: an on -site inspection of the treatment facility and a review of facility files and self -monitoring data. The following are the findings from the subject inspection: Permit The current permit became effective May 1, 2004 and expires on December 31, 2008. Less than three weeks before this inspection, Aqua took over operations of Salem Glen from Atlantic Utilities. It was apparent that Mr. Pegram and Mr. Barker were still in the process of familiarizing themselves with the plant. If not already done anew ORC designation form should be submitted immediately. Operations and Maintenance Overall housekeeping is acceptable, though rust has formed in several areas on the plant itself. A good paint job may be needed to prevent the rust from becoming a serious problem. Records/Reports A review of laboratory reports and Discharge Monitoring Reports (DMR) revealed no discrepancy between the generated data and the data submitted to DWQ. A copy of the laboratory data is kept on file. A daily visitation logbook and separate maintenance records are available for review. Self -Monitoring Program A review of the DMRs for the period of March 2007 through July 2008 did not reveal any violations. Facility Site Review When asked about the cycling of the blowers, Mr. Pegram stated that the blowers are always on and never cycled off. The DO in the aeration basin was around 0.98 mg/L on both sides of the plant during North Carolina Division of Water Quality 585 Waughtown Street; Winston-Salem, NC 27107 Phone (336) 771-5000 Customer Service: 1-877-623-6748 Internet: www.newaterquality.org Fax (336) 7714630 An Equal Opportunity/Affirmative Action Employer — 50% Recycled/10% Post Consumer Paper the inspection, which is on the low side. Mr. Pe ram agreed that adjustments could be made to bring the DO up. Floating solids and grease were observed in both secondary clarifiers, though none was observed at the discharge. The sludge blanket level was 10 feet, with 4 feet clear. Adjustments may be needed to keep the solids and rg ease from zettinZ worse. Mr. Pegram thought adjustments to the skimmers might help. Though the refrigerated effluent sampler felt cold inside, there was no thermometer to determine the actual temperature. The thermometer was the property of the previous operator and was therefore removed. Mr. Parker said new thermometers have been ordered for all of Atlantic Utility's previous facilities. Flow Measurement The flow at the plant is measured with a 90-degree V-notch weir and a model 61R Stevens Flow Meter. The flow -measuring device was last calibrated on July 26, 2008. Effluent / Receiving Waters The effluent at the outfall was clear and free of grease or solids. Sludge Handling & Disposal Forsyth Rooter handles the removal of residuals. The Compliance Inspection is satisfactory. Please refer to the underlined sections above for specific items needing attention, and to the enclose report for more detailed information.

A physical/chemical method for reducing soluble organic material from wastewater effluent; The column -type beds used in this method will have a flow rate varying from two to eight gallons per minute per square foot and may be either upfiow or downflow carbon beds. Carbon may or may not be regenerated on the wastewater treatment plant site; (2) Aerated Lagoons. A basin in which all solids are maintained in suspension and by which biological oxidation or organic matter is reduced through artificially accelerated transfer of oxygen on a flow -through basis; (3) Aeration. A process of bringing about intimate contact between air or high purity oxygen in a liquid by spraying, agitation or diffusion;(3a) Extended Aeration. An activated sludge process utilizing a minimum hydraulic detention time of 18 hours. (4) Agriculturally managed site. Any site on which a crop is produced, managed, and harvested (Crop includes grasses, grains, trees, etc.); (5) Air Stripping.

The regeneration of exhausted carbon by the use of a, furnace to provide extremely high temperatures which volatilize and oxidize the absorbed impurities; (7) Carbonaceous Stage. A sbige of wastewater treatment designed to achieve 'secondary' effluent Ilmits; (8) Centrifuge. A mechanical device in which centrifugal force is used to separate solids from liquids or to separate liquids of different densNas; (9) Chemical Addition Systems- The addition of chemicals) to wastewater at an application point for purposes of Improving solids removal, pH adjustment, alkalinity control, etc.; the capability to experiment with different chemicals and different application points to achieve a specific result will be considered one system; the capability to add chemical(s) to dual units will be rated as one system; capability to add a chemical at a different application points for different purposes will result in the systems being rated as separate systems; (10) Chemical Sludge Conditioning. The addition of a chemical compound such as lime, ferric chloride, or a polymer to wet sludge to coalesce the mass prior to its application to a dewatering device; (11) Closed Cycle Systems. Use of holding ponds or holding tanks for containment of wastewater containing inorganic, non -toxic materials from sand, gravel, crushed stone or other similar operations. Such systems shall carry a maximum of two points regardless of pumping facilities or any other appurtenances; (12) Combined Removal of Carbonaceous BOD and Nitrogenous Removal by Nitrification- A single stage system required to achieve permit eKluentt limits on BOD and ammonia nitrogen within the same biological reactor, (13) Dechlorinatlon. The partial or complete reduction of residual chlorine to a liquid by any chemical or physical process; (14) Denitrification Process. The conversion of nitrate -nitrogen to nitrogen gas; cc: Permits and Engineering Technical Support Branch Davidson County Health Dept.

During this site evaluation, it was noted that several roads had been constructed, several golf holes graded, and a small number of lots had been prepared. No apparent problems were observed with the discharge point on the Yadkin River other than the location of a small recreational boat landing approximately 1/4 mile downstream. However, this area should not be adversely affected by the NPDES Permit Staff Report discharge. PART IV-b CONCERNS First, no county zoning form was submitted with this application. A form for both Davidson and Forsyth counties should be submitted. Second, a more complete soils evaluation should be completed. The main area of concern is the Forsyth County portion of the proposed subdivision. This area should be tested for possible subsurface disposal. PART IV-c RECOMMENDATIONS WSRO recommends handling this application in accordance with Division policy.
