Box 220 Tarboro, NC 27886 Dear Mr. Lewis: NOR rr! ; A ; OL N' Environmental Quality February 1, 2022 Subject: Compliance Evaluation Inspection Tarboro WWTP NPDES Permit No. NCO020605 Edgecombe County On Thursday, January 6, 2022, Jason Robinson of the NC Division of Water Resource's Raleigh Regional Office (RRO) conducted a compliance evaluation inspection of the Tarboro Wastewater Treatment Plant (Service Road 268; Sewer Plant Rd.) The purpose of this inspection was to ensure compliance with the subject NPDES permit. During the inspection, the presence and cooperation by Mr. Kevin Peaden, Operator in Responsible Charge was appreciated. The NPDES Compliance evaluation inspection consisted of the following: • Review of the NPDES permit • Review of the Owner/facility information • Review of January 2020-November 2021 Violations • Review of January 2020-November 2021 Electronic Discharge Monitoring Reports (eDMR) and associated lab bench sheets, chain of custodies, etc. • Cursory Inspection of Tarboro WWTP on -site analytical lab • On -site inspection of the water treatment units; and • On -site inspection of the discharge outfall Findings during the pre -inspection file review were as follows: 1. The most recent permit became effective August 1, 2020 and expires on September 30, 2024. 2. The facility is a Grade IV Biological Water Pollution Control Treatment System with a permitted and as -built flow of 5.0 MGD that treats domestic and industrial wastewater and discharges through out#all 001 to the Tar River, a waterbody currently classified C, Nutrient Sensitive Waters within the Tar -River Basin. The plant is part of the Tar -Pamlico Basin Association.

Mr. Melvin Farmer and Jacob Parisher are designated back-up Operators (bORCs) and are both certified WW-4 operators. 4. For the review period January 2020 — November 2021, the following DMR violation(s) occurred: • Fecal Coliform —Weekly Geometric Mean exceed by 2.9% in November 2020. Findings during the inspection were as follows: 5. A hard —copy of an operators's log book was available for review, and all past log books are kept on -site (required to keep at least three years). The permittee is reminded to update the log books daily with conditions at the plant and any issues or maintenance that occurs. 6. As required by North Carolina General Statute § 143-215.1C(a), the City prepared a wastewater annual report for the fiscal year 2020-2021. The facility is reminded this report should be done annually, and the report should be submitted to the DWR RRO and made available to all customers. Bench sheets, chain of custody and lab results for June and October 2021 were reviewed and found to be complete. June and October 2021 bench sheet values were compared to the Electronic Discharge Monitoring Reports (eDMR) submitted by the permittee and no discrepancies were found. Past laboratory documents are kept on site (required to keep at least five years). It was observed that what was may have been an Annual Pollutant Scan was performed in October 2021, but was not reported on the eDMR and may not have been submitted to the Division. Special Condition A.(7) of the current permit requires the permittee to perform an Effluent Pollutant Scan during the calendar years 2020, 2021 and 2022, and to notify this on the appropriate eDMR and submit the results to the Division. Please see Condition A.(7) of your permit and confirm these requirements are met. This may require modifying and resubmitting you October eDMR and mailing the results to the address listed in the permit. 8. The on -site laboratory (Certification #159) is certified for and self -reports monitoring data for most of the permit -required parameters. Nutrients are analyzed by Environment 1, Inc. in Greenville. A cursory inspection of the on -site lab was done, including observing meter calibration logs, buffer expiration dates and incubator and storage temperatures. The thermometers used in the facility's self -monitoring program are NIST certified or checked against the NIST certified thermometers. No issues with the laboratory or record -keeping was observed during the cursory inspection. 9. The inspector performed a walk-thru of the plant with the assistance of the operator. The following is a list of treatment units, with comments: • Influent pump station; • Automatic & manual bar screen & grit removal — This unit is old and rusty and repair/replacement should be considered in the future (this was mentioned in the previous inspection report from January 2019); • Influent Flow Meter — Calibrated quarterly, last calibrated on 10/20/21 and is done quarterly (effluent meter is used for reporting flows); DocuSign Envelope ID: 03C79DF5-DF24-41E1-8FF3-3E6E3E685E1E • Influent Samper - Temperature <4" C • Three primary clarifiers —The uncovered weirs are typically cleaned weekly; • Two trickling filters — Only one is typically used, although the other one can be used during large flow events; • Four secondary clarifiers — Covered weirs are cleaned two/three times a year. The sludge blankets are kept at 2-3 feet; • Two aeration basins in series — older has mechanical air, newer has diffused air; • Two chlorine contact basins (chlorine gas); and liquid de -chlorination (sulfite); • Cascade aeration into the Tar River— Effluent appeared clear with no foaming; • Sludge drying beds — Have not been used in years; • Two anaerobic digesters; • Three aerobic digesters - Two of the mixers were down at the time of the inspection. The facility is currently trying to get them repaired. Based on the most recent correspondence with the operator, an electrician came out to repair them but had the wrong parts and is re- ordering new parts. The mixers should be repaired as soon as the parts arrive. Please provide a written response on the status of this; • Aerated sludge holding lagoon and truck loading area - Sludge is applied to nearby farm in Tarboro and the field beside the treatment plant by Granville Farms under Land Application Permit WQ0002047; • Effluent Sampler — Temperature <40 C; • Effluent Flow Meter — Last calibrated on 10/20/21 and is done quarterly. This is used for reporting flows; and • On -site generator — Tested and serviced regularly by the Town's Garage Department Thanks again for your cooperation with this inspection. Within 30 days, please submit a formal written response addressing the bolded Item in Section 7 and the two bolded Items in Section 9, and any other items you'd like to discuss.
