DANIEL SMITH Director NORTH CAROLINA Environmental Quality August 4, 2020 Mr. Michael Walker, Secretary Seagrove-Ulah Metropolitan Water District P.O. Box 370 Seagrove, NC 27341 Subject: Compliance Evaluation Inspection Seagrove-Ulah Metropolitan Water District WWTF Wastewater Irrigation System Permit No. WQ0002648 Randolph County Dear Mr. Walker: On July 30, 2020, staff from the Division of Water Resources (DWR) performed a compliance inspection of the Seagrove-Ulah Metropolitan Water District WWTF wastewater irrigation system. This compliance inspection was conducted by DWR staff persons Caitlin Caudle and Patrick Mitchell. Accompanying DWR staff on this inspection was Larry Chilton, ORC, and Russell Welch, Back-up ORC. This inspection of the facility reflected compliance with permit No. WQ0002648. The following items of concern were noted: 1) Per Permit Condition III.1 the facilities shall be properly maintained and operated at all times. At the time of inspection, a water diversion ditch was noted to be clogged with debris and sediment, resulting in over ground flow eroding a gravel drive leading to the sludge basin. Please repair this diversion ditch and associated piping to prevent damage to structures down gradient and limit impacts to septage trucks hauling solids from the residuals basin. 2) Per Permit Condition III.6 irrigation equipment shall be tested and calibrated at least once per permit cycle. Please calibrate the irrigation equipment by September 30, 2020 and keep the records on file for at least five years. 3) In a review of select irrigation zones two sprinkler heads were not operating correctly. Please ensure irrigation zones are being monitored to guarantee sprinkler heads are working properly and necessary repairs are being made. Please refer to the enclosed inspection report for additional comments and details from the inspection. If you have any questions related to this inspection, please contact Ms. Caudle or me D � North Carolina Department of Environmental Quality I Division of Water Resources Winston-Salem Regional Office [ 450 West Hanes Mill Road, Suite 300 I Winston-Salem, North Carolina 27105 NOh �HCARO UHA ^^ •^^ma^� u�•i` r 336.776.9800 at the letterhead address and phone number, or by email at Ion.sniderkncdenr. og_v or caitlin.caudle(cncdenr.gov.

Accompanying on the inspection was Larry Chilton, ORC and Russel Welch, BU-ORC. The facility was found to be compliant. The following items of concern were noted: • Two spray heads in soil sampling zone 1 were not operating correctly when a review of select irrigation zones was conducted. Please ensure that all irrigation heads are functional and necessary repairs are made. • A setback waiver will be required if a building close to the wastewater treatment plant is sold to a new owner. A copy of the setback waiver was provided after the inspection via email. • A storm water diversion ditch and associated underground piping were noted to need repair. The ditch appeared to be clogging the pipe with sediment and debris, causing water to flow over ground and erode the driveway leading to the sludge basin. This could impact septage trucks attempting to haul solids from the sludge basin, and potentially impact the down gradient structures. • A separate review of March and April's monthly self monitoring reports showed missing parameters and flow not being monitored continuously. The permit requires reporting flow through the wastewater plant continuously and certain parameters be sampled three or four times a year. Please report flow continuously on future NDMRs and monitor parameters at required frequencies. This will be addressed in a separate correspondence. • The irrigation system had not been calibrated to date. The permit requires irrigation systems to be calibrated once per permit cycle. A calibration document was provided after the inspection via email, once the calibration is complete please keep a copy with your records. A reminder the current permit expires September 30, 2020. • Residuals removal records are kept with daily maintenance logs. Moving forward, please keep copies of the receipts from the residual hauler. • Flow meters measuring influent flow are not included in the current permit description. • An Operations and Management Plan was not present on site. An engineer has been hired to design an O&M plan that better represents the current flow path and operations. • The pumps meant to transfer effluent from the existing lagoon to the new lagoon are not connected to the new lagoon Before operation of the new lagoon, the pipes connecting the pumps and new lagoon should be installed. • The first splitter box receiving influential flow has two pipes open that lead directly to the effluent storage pond and to the industrial treatment lines. These pipes could lead to potential bypasses of the treatment system during high flow events. Staff appreciate the extra care taken by ORCs with the maintenance of the wastewater system and irrigation system.
