The NOV is based on the January 26, 2021 inspection performed by the North Carolina Division of Water Resources (DWR), which identified numerous weeds and moisture-tolerant grasses present in the irrigation field. This observation was found to be non-compliant with wastewater irrigation system permit (Permit No. WQ0004967) condition III (Operation and Maintenance Requirements) paragraph 3, requiring that a suitable year-round vegetative cover shall be maintained at all times. In addition to the condition of the irrigation field, the NOV also noted a potential compliance issue related to the influent pipe that conveys wastewater from the AllJuice facility to the wastewater storage pond. In response to these non-compliance issues, a summary of the corrective actions currently underway and a schedule of implementation is provided below. Background The following correspondence provides the background for compliance issues identified by DWR, the assessments that have been completed to evaluate the compliance issues, and the corrective measures that AllJuice is currently pursuing: • October 2017 – DWR, Notice of Violation and Intent to Enforce • June 2018 – Anchor QEA, Notice of Violation and Intent to Enforce Response March 31, 2021 Page 2 • March 2019 – DWR, Review of the Notice of Violation and Notice of Intent to Enforce Response Report and Required Corrective Action Measures • April 2020 – Anchor QEA, Corrective Action Assessment Report (CAAR) • September 2020 – Anchor QEA, Off-Site Assessment and Pipe Inspection Results The April 2020 and September 2020 reports, submitted by Anchor QEA, on behalf of AllJuice, describe assessment activities that were performed to determine appropriate corrective actions. Permit Condition III-3 In response to the violation of permit condition III-3, the April 2020 CAAR recommended the following activities to improve the assimilative capacity of the irrigation fields: • Remove weeds and reestablish the fescue cover crop. • Initiate a maintenance program where mowing and mowed-crop removal are routinely performed. • Apply gypsum or similar soil amendment to break the sodium binding in the soils. • Alternate wetting and drying application periods in the field to promote better microbial activity and root growth. • Consider planting trees along the perimeter of the field to develop a deep root system to enhance treatment. Anchor QEA is implementing the recommended activities for the irrigation fields. Actions that have been completed or will complete in 2021 include the following: • November 2020 – Soil samples were collected from the irrigation fields to determine the required volume of gypsum to apply to fields. • January to February 2021 – A gypsum vendor has been identified that can supply the volume required for soil treatment and deliver it to the site in April 2021. • April 2021 – Apply a selective herbicide to the application fields. • May 2021 – Amend soil with first application of gypsum, allowing adequate adsorption period in between applications. • June to August 2021 – Initiate a more aggressive crop/grass cutting, harvest and removal program for application fields. • August to September 2021 – Reseed application fields with Tall Fescue grass. • September to October 2021 – Apply selective herbicide to the application fields (may be spot application). • November 2021 – Amend soil with second application of gypsum. • March to April 2022 – Reseed application fields with Tall Fescue grass (if needed). • May 2022 – Amend soil with final application of gypsum. March 31, 2021 Page 3 Influent Line to Wastewater Storage Pond The influent line to the wastewater storage pond was assessed using a pipe camera on February 25, 2020, to evaluate the source for fecal coliform found in the wastewater treatment system irrigation storage pond1. As described in the September 2020 Off-Site Assessment and Pipe Inspection Results, the pipe camera identified a section of pipe that had been repaired in the past. The location of the repair is in the vicinity of the former septic system and is the likely source of the fecal coliform detected in the storage pond. The excavation noted by the DWR inspector was related to an existing conditions survey performed during the week of January 5, 2021, which used air-knife excavating to expose buried piping around the storage pond. This excavation was not related to assessment or repair of the influent pipe. The damaged section of piping is believed to have occurred in 1999, based on a Henderson County septic system repair permit, which describes the wastewater line as being in close proximity to the septic drain field. Review of the pipe camera video shows the damaged section of piping occurring on the top half of the pipe; the bottom half appears to be intact (Figure 1). This suggests that meteoric water from precipitation events may enter the pipe (and introduce fecal coliform); however, the wastewater from the plant does not appear to rise to the level of the repaired section of the pipe (Figure 1). Anchor QEA has initiated the design process for modifying the storage pond and installing a pond liner. As part of this process, the influent pipe will be repaired and rerouted to accommodate the new pond design. Anchor QEA requests that the pipe repair be deferred until the construction phase of the project, which is estimated for 2022. Presently Anchor QEA has completed an existing conditions survey to document the surface elevation, bathymetry, and elevations and directions of sub-surface pipes and utilities around the pond. Anchor QEA is currently working on the pond modification design. Closing On behalf of AllJuice, Anchor QEA appreciates the DWR’s time and consideration as we work through these compliance issues. Work is moving forward with regard to the pond modification design, which will address the influent pipe repair. Our engineering team will be reaching out to the DWR in April 2021 to schedule a pre-application meeting to discuss our proposed pond modification design. Afterward our team will be working on the final design and permitting. We anticipate assisting AllJuice with contractor selection for design implementation in early 2022. Between now and late fall 2021, we will be working on irrigation field improvements. Attachment 1 provides a general schedule 1 Assessment performed in response to the requirements set forth in the March 5, 2019 Notice of Violation and Notice of Intent to Enforce Response Report and Required Corrective Action Measures, North Carolina Division of Water Resources March 31, 2021 Page 4 for the planned activities. Should the DWR have questions or concerns, please do not hesitate to contact me by email or phone (828.771.0378).

Image has been rotated 35 degrees to horizontal. Dashed yellow line shows the high water mark in the pipe. Dashed blue line shows the level of the wastewater on February 8, 2020. The high water mark is below the damaged area of the pipe. The pipe appears intact below this area and does not allow wastewater to discharge to subsurface soils. Meteoric water from precipitation event does have the opportunity to enter the pipe through the repaired section. During the implementation of the pond design, this section of the influent pipe will be repaired.
