ROGERS, JR. Director NORTH CAROLINA Environmental Quality May 4, 2022 Certified Mail 7017 2680 0000 2235 8663 Return Receipt Requested James Buddy Gwaltney, Mayor Town of Spring Hope PO Box 87 Spring Hope, NC 27882 Subject: Notice of Violation NOV-2022-PC-0258 Compliance Evaluation Inspection Town of Spring Hope WWTP NPDES Permit No. NC0020061 Nash County Dear Mr. Gwaltney: On March 23, 2022, Colleen Cohn and Mitchell Hayes of the Raleigh Regional Office (RRO) conducted an inspection at the subject facility. The cooperation of William Lamm of Envirolink Inc., Operator in Responsible Charge (ORC) of the facility, was greatly appreciated. Findings during the inspection were as follows: 1. The current NPDES permit was issued effective on August 1, 2020 and will expire on October 31, 2024. A copy of the current NPDES permit was not available on -site. A copy of the previous NPDES permit, which expired October 31, 2019, was available. Please ensure that a copy of the current NPDES permit is available on -site. 2. The 0.40 MGD wastewater package treatment plant consists of mechanical and manual bar screens, manual grit removal, influent ultrasonic flow meter, two (2) aeration chambers, two (2) circular clarifiers, one (1) aerobic digester, two (2) tertiary clarifiers, liquid chlorination and contact chambers, cascade aeration, and liquid de -chlorination and contact chambers. 3. The plant discharges to the Tar River which is classified as WS-V; NSW waters in the Tar -Pamlico River Basin. 4. Envirolink, Inc. is contracted to operate the WWTP. The primary ORC is William Lamm. The ORC logbook was readily available for review and up to date.

The mechanical bar screen was not operable at the time of the inspection and a moderate amount of debris buildup was observed on the bar screens. Our records indicate that the mechanical bar screen was also not operable during the inspections conducted on April 22, 2015 and November 14, 2018. Additionally, the motor for the mechanical bar screen appeared to have been removed. Within 30-days receipt of this letter, please submit a written response to this office outlining the schedule you will take or have taken to repair the mechanical bar screen and bring it back into operation. 6. The influent flow meter was calibrated on September 15, 2021, by Chadwick Instrument Service. During the inspection, the chart recorder was not recording due to a dropped pen. Mr. Lamm replaced the pen during the inspection. 7. At the time of the inspection, the high-level float in the influent flow channel was not operational. Mr. Lamm stated that this high-level float failure attributed to the March 17, 2022, Sanitary Sewer Overflow (SSO) for the Spring Hope Collection System, (Collection System Permit Number #WQCS00206) at the manhole outside of the wastewater treatment facility when the pump tripped out. The total volume of the SSO was reported as 500 gallons, with 100 gallons reaching surface waters at Hendricks Creek. Mr. Lamm stated that an electrician was scheduled to return to complete repairs to the high-level float. Within 30-days receipt of this letter, please submit a written response to this office outlining the schedule you will take or have taken to repair the high-level float. 8. Both secondary clarifiers operate at a depth of approximately 15 feet. Mr. Lamm stated that he did not know the depth of the sludge blanket and did not have a sludge judge. Mr. Lamm stated that he performs settleability tests and operates the clarifiers at approximately 350 ml. The Division highly recommends having a sludge judge readily available. 9. Grease and duckweed were observed in the two tertiary clarifiers. Mr. Lamm stated that the pumps for grease removal were not operational. Within 30-days receipt of this letter, please provide a written response to this office outlining the schedule you will take or have taken to repair the grease removal pumps. 10. The liquid chlorination system appeared to be operating satisfactorily. 11. The liquid de -chlorination system appeared to be operating satisfactorily. 12. The effluent at Outfall 001 could not be observed during the inspection as the Tar River was too high and the outfall pipe was underwater. Observation of the disinfection contact chambers and cascade aeration indicate that effluent was clear and free of excess solids.

As stated by the operator, the fecal coliform samples are collected offsite at a manhole located prior to the outfall, while the composite sampler is located within the facility. All effluent samples (composite and grab) should be taken at the same effluent location. 14. The refrigerated effluent composite sampler was not operational at the time of the inspection. Mr. Lamm stated that a portable composite sampler is being used. The portable composite sampler was not on site during the inspection. Within 30-days receipt of this letter, please provide a written response to this office indicating the Standard Operating Procedures (SOPs) for collecting samples using the portable composite sampler and ensuring the sample is maintained at or below 6° C. 15. Mr. Lamm stated that Granville Farms hauls sludge from the facility twice per year. 16. Mr. Lamm stated the two onsite diesel generators are tested weekly and sometimes tested under load. The generators appeared to be operating satisfactorily during the inspection. 17. The field parameters performed by the operator are pH, Temperature, and Dissolved Oxygen. Meritech, Inc. (Certified Lab #165), performs analysis for all other permitted parameters. Envirolink, Inc. (Certified Lab #5212) conducts the field parameter sampling required by the permit. 18. A cursory review of laboratory data and discharge monitoring report (DMR) data for February 2021 and June 2021 showed compliance with the permit limits 19. A cursory review of discharge monitoring report (DMR) data for January 2021 to present was performed. Average flow data between January and February 2022 ranged from a high of 0.30 MGD in February 2021 as low as 0.04 MGD in November 2021. Within 30 days receipt of this letter, please provide a written response detailing the fluctuation in the flow data. 20. A review of DMR data for January 2021 to present showed three DMR violations. In May 2021, the operator failed to add a weekly Total Nitrogen and Total Phosphorus result to the DMR, which was revised in August 2021. In both October 2021 and December 2021, the second monthly ammonia (NH3) sample required by the permit was not collected. Mr. Lamm stated that they are now sampling for ammonia weekly. 21. The field parameter calibration logs for the months of February 2021 and June 2021 were not available onsite for inspection and review. Mr. Lamm stated that the Operators Logs containing the field parameters are turned in to Envirolink monthly for DMR submittal and storage. Within 30-days receipt of this letter, please provide the field parameter calibration logs for the months of February 2021 and June 2021. 22. Mr. Lamm stated that the pH vessels containing the pH standards 4.0, 7.0 and 10.0 are poured up weekly. Only pH 4.00 and 10.00 buffers were available on site, and the buffers £ D_E NORTHCAROLINA Department of Environmental Deal North Carolina Department of Environmental Quality I Division of Water Resources Raleigh Regional Office I 3800 Barrett Drive I Raleigh, North Carolina 27609 919.791.4200 DocuSign Envelope ID: 6779F84A-3E89-4F69-88BA-B542D4FCODDD Town of Spring Hope WWTP NPDES Permit No. NC0020061 Nash County Page 4 of 4 were both expired. A portion of the standard buffer is not to be used for more than one calibration. The used buffer portions must be discarded after each use. Also, when performing analyses at multiple sample sites, a post -analysis verification using the check standard buffer must be analyzed at the end of the run. Within 30-days receipt of this letter, please provide in writing the Standard Operating Procedures (SOPs) for calibrating the pH meter and collecting pH samples. As required by Part II, Section C.2 of the subject NPDES permit, "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." Please respond in writing to items 1, 5, 7, 8, 9,14,19, 21, and 22 within 30 days of receipt of this letter describing how these items have been resolved.
