The last compliance evaluation inspection at the facility was performed by DWR staff on 10/25/18. Record Keeping Are records kept and maintained as required by the permit? Is all required information readily available, complete and current? Are all records maintained for 3 years (lab. reg. required 5 years)? Are analytical results consistent with data reported on DMRs? Is the chain -of -custody complete? Dates, times and location of sampling Name of individual performing the sampling Results of analysis and calibration Dates of analysis Name of person performing analyses Transported COCs Are DMRs complete: do they include all permit parameters? Has the facility submitted its annual compliance report to users and DWQ? (If the facility is = or > 5 MGD permitted flow) Do they operate 24/7 with a certified operatc on each shift?

Discharge Monitoring Reports (eDMRs) were reviewed for the period June 2019 through May 2020. Nc effluent limit violations were reporting and all monitoring frequencies were correct. The ORC and staff must ensure that the minimum 10-day interval between the collection of the twice per month effluent ammonia samples is adhered to during all future sampling events. . Laboratory Yes No NA NE Are field parameters performed by certified personnel or laboratory? 0 ❑ ❑ ❑ Are all other parameters(excluding field parameters) performed by a certified lab?

DH. temDerature. total residual chlorine) are performed under Envirolink's field laboratory certification #5212. Statesville Analytical (Certification #440) has also been contracted to provide analytical support. The ORC was not performing post -analysis calibration checks on the pH meter following field analyses at multiple sites. Post -analysis calibration checks must be performed in accordance with the NC Wastewater/Groundwater laboratory certification approved procedures for the analysis of PH. Effluent Sampling Yes No NA NE Is composite sampling flow proportional? ❑ ❑ 0 ❑ Is sample collected below all treatment units? 0 ❑ ❑ ❑ Is proper volume collected? 0 ❑ ❑ ❑ Is the tubing clean? ❑ ❑ 0 ❑ # Is proper temperature set for sample storage (kept at less than or equal to 6.0 degrees ❑ ❑ 0 ❑ Celsius)? Is the facility sampling performed as required by the permit (frequency, sampling type 0 ❑ ❑ ❑ representative)? Comment: The subject permit requires effluent grab samples. The ORC and staff must ensure that all samples are collected following all treatment processes and at this facility. Effluent samples would be collected after the in -ground filtration (gravel) tank at this facility. Operations & Maintenance Yes No NA NE Is the plant generally clean with acceptable housekeeping? 0 ❑ ❑ ❑ Page# 4 Permit: NCO023191 Owner -Facility: Seven Cedars Mobile Home Park WWTP Inspection Date: 07/16/2020 Inspection Type: Compliance Evaluation Operations & Maintenance Yes No NA NE Does the facility analyze process control parameters, for ex: MLSS, MCRT, Settleable ❑ ❑ ❑ Solids, pH, DO, Sludge Judge, and other that are applicable? Comment: The wastewater treatment facility appeared to be properly operated and well maintained. Process control measurements were being performed and documented. Bar Screens Yes No NA NE Type of bar screen a.Manual b.Mechanical ❑ Are the bars adequately screening debris? 0 ❑ ❑ ❑ Is the screen free of excessive debris? 0 ❑ ❑ ❑ Is disposal of screening in compliance? 0 ❑ ❑ ❑ Is the unit in good condition? 0 ❑ ❑ ❑ Comment: Aeration Basins Yes No NA NE Mode of operation Ext. Air Type of aeration system Diffused Is the basin free of dead spots? 0 ❑ ❑ ❑ Are surface aerators and mixers operational? ❑ ❑ 0 ❑ Are the diffusers operational? 0 ❑ ❑ ❑ Is the foam the proper color for the treatment process? N ❑ ❑ ❑ Does the foam cover less than 25% of the basin's surface? 0 ❑ ❑ ❑ Is the DO level acceptable? 0 ❑ ❑ ❑ Is the DO level acceptable?(1.0 to 3.0 mg/1) 0 ❑ ❑ ❑ Comment: Lime is added on an as -needed basis to maintain appropriate alkalinity/pH levels. Secondary Clarifier Is the clarifier free of black and odorous wastewater? Is the site free of excessive buildup of solids in center well of circular clarifier? Are weirs level? Is the site free of weir blockage? Is the site free of evidence of short-circuiting? Is scum removal adequate?

The ORC/Permittee must ensure that an adequate sludge wasting - program is implemented to maintain an appropriate solids inventory. Flow Measurement - Effluent Yes No NA NE # Is flow meter used for reporting? ❑ ❑ 0 ❑ Is flow meter calibrated annually? ❑ ❑ 0 ❑ Is the flow meter operational? ❑ ❑ 0 ❑ (If units are separated) Does the chart recorder match the flow meter? ❑ ❑ 0 ❑ Comment: Instantaneous flow measurements are Derformed by the bucket and stop watch method. The ORC and staff must ensure to measure flow during the collection of effluent samples (BOD, TSS, ammonia, etc.). Effluent Pipe Yes No NA NE Is right of way to the outfall properly maintained? ❑ ❑ ❑ Are the receiving water free of foam other than trace amounts and other debris? ❑ ❑ ❑ If effluent (diffuser pipes are required) are they operating properly? ❑ ❑ 0 ❑ Comment: The facility was not discharging at the time of the inspection; however, the treated wastewater in V-notch weir box (following clarification) appeared clear with no floatable solids.
