Box 1006 Liberty, NC 27298 NORTH CAROLINA Environmental Quality May 2, 2022 SUBJECT: Notice of Deficiency (NOD-2022-PC-0065) Town of Liberty, Wastewater Irrigation Permit No. WQ0003090 Randolph County Dear Mr. Kidd: On April 12, 2022, Division of Water Resources staff Caitlin Caudle conducted a routine compliance inspection. Tremaine Fike, ORC, was present during the entire inspection, and Todd Kellam, back up ORC in -training, was present during part of the inspection. A review of records, treatment facilities, spray fields, and monitoring wells was completed. This review reflected non-compliance with the subject permit. The following deficiency was noted: 1. Per correspondence dated September 3, 2021, the Winston Salem Regional Office requested that the freeboard marker in the lagoon be resurveyed and reinstalled before the end of the 2021 calendar year. Extensions were requested and granted, moving the deadline to February 28, 2022. At the time of inspection, the freeboard marker had not been resurveyed or reinstalled. Per Permit Condition 111.14 "a gauge to monitor waste levels in the 15-acre stabilization storage lagoon shall be provided. This gauge shall have readily visible permanent markings, at inch or tenth of a foot increments, indicating the following elevations: maximum liquid level at the top of the temporary liquid storage volume; the minimum liquid level at the bottom of the temporary liquid storage volume, and the lowest point on top of the dam." The maximum liquid level is at 720ft elevation, and the minimum liquid level is 713 ft elevation. Please resurvey the freeboard marker by May 30, 2022. GDE NORTH CAROLINA ' D. mmm�� .ore�nt o�.i North Carolina Department of Environmental Quality I Division of Water Resources Winston-Salem Regional Office 1450 W. Hanes Mill Rd, Suite 300 I Winston-Salem, North Carolina 27105 336.776.9800 The following item of concern was noted: A. Vegetation overhanging the spray fields was noted in the inspection report for compliance inspection dated August 30, 2022. As of this inspection, vegetation has not been cut back due to lack of man -power and equipment. Overhanging vegetation can impact the spray pattern of sprinklers and can cause channelized flow. Please take steps to remove vegetation overhanging spray zones that could be impacting spray patterns. B. The hinge on lid of Monitoring Well 7 was broken. Per Permit Condition 11.3 "groundwater monitoring wells shall be constructed in accordance with 15A NCAC 02C .0108..." As described in 15A NCAC 02C .0108, repair the hinge on MW7 so that the lid is secure if not done so already. C. Maintenance activities completed by the farmer contracted to manage the spray fields has not been recorded in the operations and maintenance log for the facility. Per Permit Condition V.2 "The Permittee shall maintain an inspection log that includes the date and time of inspection, observations made, and maintenance, repairs, or corrective actions taken." Moving forward, please begin recording all maintenance activities (e.g.; herbicide application, seeding, or lime application) in the spray fields in the operation and maintenance log. Please refer to the enclosed inspection report for additional comments and observations. If you have any questions please contact me or Caitlin Caudle at the letterhead address or phone number, or by email at lon.snider@ncdenr.gov or caitlin.caudle@ncdenr.gov.

Moving forward, please begin recording all maintenance activities (e.g.; herbicide application, seeding, or lime application) in the spray fields in the operation and maintenance log. Other observations: • Todd Kellam will be taking operator test in June. Gregory Hanyok retired on 4/14/2022. A new back up operator must be designated within 120 days of Mr. Hanyok retiring (08G .0200 (3)(b)(i)). • Zones 1, 2, 3A, and 8B were reseeded last winter. Vegetation had sprouted and was approximately 6" tall in all zones. • Part of Z1 (marked on field map) was sprayed with herbicide to kill weeds and reseeded. • A diagram was left explaining how the freeboard marker should be installed with all necessary depths marked. • The previously noted wet spot in Z1 was dry. Swamp gras was still visible. • The valve between 3 and 4 was repaired but the immediate area around the valve still needs vegetation established. • The first quarterly report for 2022 was provided. • Irrigation equipment must be calibrated by August 31, 2024. • Lime was not called for in soil reports. • Liquid chlorine is delivered. • Some floating solids were present in the chlorine contact chamber. Mr. Fike stated he would remove the solids when the lagoon level lowered. • Two sediment basins are present on the side of the lagoon next to North Rocky Fork River. • The flow meter was last calibrated on 11/6/2021. • The effluent pump station has a lower water float that cuts off the irrigation system. • All other monitoring wells were in good condition. • Additional nitrogen may be applied to the spray fields to ensure that optimum crop health is reached. Staff recommend that additional nitrogen only be applied during the active growing season, May — October. Below is a table of recommended Page 2 of 7 Permit: WQ0003090 Owner - Facility:Town of Liberty Inspection Date: 04/12/2022 Inspection Type : Compliance Evaluation Reason for Visit: Routine Plant Available Nitrogen (PAN) rates for each spray zone based on the North Carolina State University Realistic Yield Database. Be sure that nitrogen applications do not exceed the recommended rates. PAN is present in irrigated effluent, and the amount of PAN to be irrigated during the entire year must be calculated and subtracted from the recommended PAN rates below. The highest nutrient rates analyzed to date must be used to calculate PAN. If additional assistance is needed, please contact the Winston Salem Regional Office.
