Brent Collins and Roy Whitaker of EMA Resources, Inc. were present during the entire inspection. Mr. Collins accompanied Ms. Caudle to review additional application fields for permitting purposes. This review reflected compliance with the subject permit. The following item of concern was noted: A. Per Permit Condition V.2 "prior to each bulk residuals land application event, the Permittee or his designee shall inspect the residuals storage, transport, and application facilities to identify malfunctions, facility deterioration and operator errors ... The permittee shall maintain an inspection log that includes, at a minimum, the date and time of inspection, observations made, and any maintenance, repairs, or corrective actions taken...." Mr. Collins stated that a record of field inspections is not available, but all fields are inspected and flagged prior to application activities. Moving forward, please keep a log of all field inspections prior to the commencement of land application activities. DV-08-01 Field Observations: • Additional sources have not been applied to DV-08-01 this year. • Field conditions were acceptable for land application. • All buffers were flagged. • Surface application is used. • Fescue pasture was the intended crop. • Public access signs were posted at the fence line next to the cul-de-sac on Bunker Way and at the gate that immediately accesses the field on South Benson Lane. • The application area was being accessed by a gate on Walt Wilson Road approximately 0.3 miles from the application areas and the other posted signs. Other observations: • Two storage structures are present that serve as storge and treatment. A 176,000 gallon and a 253,700 gallon digestor store residuals, with approximately 90 days of storage. Aeration is present in both digestors. No other storage is present. • A sludge thickening process was implemented with the plant expansion, but it has not been utilized yet due to issues with water pressure. The process is introducing polymers to the wasted sludge, running the sludge through a rotary screen, and wasting the thickened sludge into the digestors. The current sludge thickening process is manually decanting wastewater from settling sludge. • Mr. Collins stated that application equipment is calibrated when initially purchased and after maintenance activities. • Mr. Whitaker stated that the WWTP has an application event every 3-4 months with approximately 50 dry tons per event. Samples are collected from the digestor that is being emptied. • Mr. Collins stated that they do not reach 250 dry tons per year and that amount was permitted to have a buffer. • Pumper truck 606 was being used. This truck has a 4,500 gallon capacity. Hauling records, current permit, and O&M plan were in the truck. The rain gauge was also on the pumper truck, which is kept at the WWTP over night during application events. • Fecal coliform density and 30 day bench test were used for the most recent application event to ensure compliance with Pathogen and Vector Reduction requirements. • According to the 2021 Annual Report no lime amendments were recommended for the application fields.

The Operations Manager or the person in charge on the spill site will be advise the clean-up personnel where to get the straw, lime, and other items necessary to complete the clean-up operation. ie. local farmers, farm supply centers, nurseries. iv. Initial Clean -Up: Employ front-end loaders, vacuum equipment, sludge application vehicles, and/or local septic tank service to remove as much of the spilled material as possible. Straw and/or sand should be scattered in the spill area to soak up the remaining material. The straw and sand soaked material will be collected and removed to a disposal area approved by representatives of the state regulatory agency. v. Final Clean -Up: Employ rotary brush sweeper if needed and apply lime to the spill area upon the approval of the clean-up efforts by the state regulatory representative. If the event occurs on private property, the clean-up will be completed to the satisfactory of the property owner and state regulatory representatives. The ultimate goal will be restore the spill area to its original condition if possible. vi. Notification: As soon as possible after the spill occurs, the EMA Resources Project Manager or designee will notify the Town of Mocksville and the EMA Resources main office. EMA Resources office staff is then responsible for notifying other key EMA Resources personnel. vii. Reporting: EMA Resources staff will notify the Winston-Salem regional office of the NCDENR by telephone (336) 776-9800 as soon as possible, but not more than 24 hours after, or on the next working day following the occurrence.
