Violation and Notice of Intent to Enforce Responseiii June 2018 1Introduction AllJuice Realty, LLC (AllJuice), operates a juice bottling facility located at 352 Jet Street in Hendersonville, North Carolina (the site). The non-sanitary wastewater generated from the facility is conveyed to a treatment pond. The wastewater is aerated in the treatment pond. Following aeration, the wastewater is sprayed onto adjacent fields when conditions allow. The North Carolina Department of Environmental Quality (DEQ) authorizes the treatment and land application of the wastewater under Permit Number WQ0004967. This permit is in effect from April 27, 2017, to March 31, 2022. As a condition of the permit, groundwater samples are collected from monitoring wells MW-1, MW-2, and MW-3 three times per year and submitted for laboratory analysis. A site location map is shown in Figure 1. Operation, monitoring, and maintenance of the treatment and land application system, including compliance sample collection, is performed by AllJuice’s licensed operator in responsible charge, James & James Environmental (James & James). 1.1Background 1.1.1Permit Modification Letter On April 27, 2017, AllJuice received a permit modification letter (Permit Number WQ0004967) from the DEQ’s Division of Water Resources. As part of the permit modification, DEQ requested existing background monitoring well MW-1 be replaced due to historically low water levels or dry conditions in the well. In addition, the DEQ cited in its letter 2016 and 2017 analytical results from compliance monitoring samples collected from monitoring well MW-2, which had concentrations of total iron, total manganese, and ammonia greater than the Title 15A Subchapter 02L .0202 of the North Carolina Administrative Code (2L groundwater standards). 1.1.2Notice of Violation and Notice of Intent to Enforce The DEQ issued a Notice of Violation and Notice of Intent to Enforce (NOV-NIE) on October 15, 2017 (DEQ 2017). The NOV-NIE requirements are summarized as follows: Violation 1 – Permit Condition Violation (NOV-2017-PC-0649): The existing background monitoring well MW-1 is often dry. As part of the April 2017 permit, the following conditions were outlined and not completed: Replace the background monitoring well by July 2017. Update the site map with the location of the new background well. Violation 2 – Violation of 2L groundwater standards (NOV-2017-LV-0672, NOV-2017-LV-0673, NOV-2017-LV-0674, and NOV-2017-LV-0675): Analytical results of compliance monitoring samples collected from monitoring well MW-2 indicate concentrations of total iron, total manganese, and ammonia that exceed their respective 2L groundwater standards. Notice of Violation and Notice of Intent to Enforce Response1 June 2018 1.1.3Response Actions Anchor QEA of North Carolina, PLLC (Anchor QEA), completed several activities in response to the NOV-NIE. The requirements DEQ listed in the NOV-NIE and the response actions taken by Anchor QEA on behalf of AllJuice are as follows: 1.Provide an explanation for why the permit condition requiring a new background monitoring well was not fulfilled. a.A statement to address this requirement was provided in the Work Plan to Address the Requirements of the Notice of Violation and Notice of Intent to Enforce (Anchor QEA 2017), dated November 15, 2017. 2.Identify a new background monitoring well location and provide an updated site map showing its location. a.The new background monitoring well location was identified, the well was installed, and on December 5, 2017, Anchor QEA emailed documentation to the DEQ (Appendix A). Additionally, representatives of AllJuice and Anchor QEA presented the updated site map to DEQ during a meeting held at the DEQ, Asheville Regional Office on February 27, 2018. The updated site map is shown in Figure 2. 3.Implement low-flow sampling to reduce turbidity to less than 10 nephelometric turbidity units (NTUs) at the time of sample collection. a.Anchor QEA performed low-flow sampling at the site and achieved less than 10 NTUs at each groundwater sampling location. Anchor QEA informed James & James of the low- flow requirement for compliance monitoring, and James & James intends to perform future compliance monitoring using low-flow sampling methods. 4.Assess the cause, significance, and extent of the violation of the 2L groundwater standards and submit the results of the investigation along with a plan and proposed schedule for corrective action. a.Anchor QEA has assessed the cause, significance, and extent of the 2L groundwater standard violations. The remaining sections of this report address this action. 5.Assess the conditions within the wastewater irrigation pond to determine whether a buildup of organic solids and low dissolved oxygen conditions are contributing to the groundwater violations. a.James & James performed this work in September 2017, and the results of its investigation are provided in Appendix B. Anchor QEA also assessed the pond and confirmed the findings of James & James. Anchor QEA and AllJuice presented these data to DEQ during the February 27, 2018 meeting and have provided these data in this report as well. 6.Perform a limited water receptor survey to determine whether water supply wells exist in the immediate vicinity of the wastewater irrigation pond. Notice of Violation and Notice of Intent to Enforce Response2 June 2018 a.Anchor QEA completed a limited receptor survey and presented the results to DEQ during the February 27, 2018 meeting. The results of the receptor survey are also included in this report. 1.2Report Purpose On behalf of AllJuice, Anchor QEA has completed a series of assessment activities. Anchor QEA performed the activities to assess the cause of violations of 2L groundwater standards observed in the samples collected from monitoring well MW-2. Assessment activities included the installation of two monitoring wells (one new and one replacement), low-flow sampling of on-site monitoring wells, collection of samples from the wastewater treatment pond, and collection of water samples from the drainage ditch located east of the pond. Anchor QEA identified potential sources that may be responsible for the impacts to on-site groundwater. Those potential sources were presented to the DEQ in a meeting held at the DEQ, Asheville Regional Office on February 27, 2018. The potential sources include the on-site treatment pond, the spray irrigation field, and the septic drain field, which is associated with a separate system for sanitary wastewater treatment and disposal permitted by the Henderson County Health Department. The purpose of this report is to summarize and consider the historical data and data collected during recent assessment activities with respect to the potential source areas identified on site. A description of the scope of services performed, methods used, and summary of the results is provided in the following sections. Notice of Violation and Notice of Intent to Enforce Response3 June 2018 2Site Investigation Work activities were completed in general accordance with the Work Plan to Address the Requirements of the Notice of Violation and Notice of Intent to Enforce (Anchor QEA 2017), dated November 15, 2017, and approved by DEQ on December 5, 2017, by email. The completed scope of work involved the installation of two additional groundwater monitoring wells and the sampling of the site’s groundwater monitoring wells, wastewater present in the treatment pond, influent to the treatment pond, effluent from the treatment pond, and water present in a ditch located between the treatment pond and the on-site septic drain field (Figure 3). Anchor QEA also completed a limited receptor survey to identify water supply wells near the site. In addition to the work performed by Anchor QEA, James & James performed an assessment of the treatment pond in September 2017. James & James collected 12 samples from the bottom of the treatment pond and measured the depth of the accumulated solids. These results are provided in Appendix B. Anchor QEA designed the 2017 Work Plan to Address the Requirements of the Notice of Violation and Notice of Intent to Enforce to assess the potential sources of the violations of the 2L groundwater standards observed in samples collected from monitoring well MW-2. At the time Anchor QEA wrote the work plan, the potential source areas included the treatment pond, the spray field, and the septic drain field, which is associated with a separate system for sanitary wastewater treatment and disposal permitted by the Henderson County Health Department. During site investigations, Anchor QEA identified a fourth potential source area: the drainage ditch between the septic drain field and the treatment pond. This ditch receives stormwater runoff from the spray irrigation fields and conveys it off-site to a tributary to Wolfpen Creek. During a November 2017 site visit, Anchor QEA noticed a breach in the eastern bank of the drainage ditch. This breach was located at the northern end of the septic drain field. Anchor QEA modified the work plan to evaluate the ditch as well. 2.1Monitoring Well Installation and Well Development On October 25, 2017, Anchor QEA provided the DEQ with a letter describing the proposed location and construction details of the new background monitoring well to be installed as a replacement for the current background monitoring well, MW-1. On October 31, 2017, Bret Laverty with the DEQ sent an email to Anchor QEA agreeing with the chosen well location, provided that it is outside of the influence of the spray irrigation system. Anchor QEA oversaw the installation of the new background monitoring well, MW-5, on November 28 and 29, 2017. Additionally, a monitoring well (MW-6) was installed in between the treatment pond and the septic system leach field on April 2, 2018. The monitoring wells were installed by South Atlantic Environmental Drilling and Construction Company, Inc., a North Carolina- Notice of Violation and Notice of Intent to Enforce Response4 June 2018 licensed drilling company. Monitoring wells MW-5 and MW-6 locations are shown in Figure 2, and well construction information is included in Table 1. Monitoring well MW-5 was installed using hollow-stem auger and air hammer drilling technology. Monitoring well MW-6 was installed using hollow-stem auger drilling techniques only. The monitoring wells were constructed with 2-inch-diameter Schedule 40 polyvinyl chloride (PVC) well materials. A 0.01-inch machine-slotted PVC screen was set to a depth perceived, at the time of installation, to intersect the water table at each well location. No. 2 filter sand was then used to fill the annular space between the well screen and the borehole to a depth of approximately 2 feet above the top of the well screen. Approximately 3 feet of hydrated bentonite pellets were placed above the filter sand. A cement grout mixture was used to fill the annular space to within 1 foot of the ground surface. Both wells were completed with approximately 3 feet of riser aboveground and protected with an outer steel vault with a hinged, lockable lid. Boring logs and well construction records are provided in Appendix C. After installation, MW-5 and MW-6 were developed using the surge-and-bail method and purged using a submersible Whale pump. Approximately 85 gallons of water were purged from monitoring well MW-5, and approximately 255 gallons of water were purged from monitoring well MW-6. Additionally, monitoring wells MW-1 (former background well), MW-2, and MW-3 were redeveloped using a Waterra pump. While development was performed, the surge block on the Waterra pump was positioned in different depth intervals of the screen, starting at the bottom of the well and moving up, until the surge block had been applied to the entire screened interval. Each well was developed for up to 4 hours. Well development logs are provided in Appendix D. 2.2Groundwater Sample Collection After well installation and well development were complete, Anchor QEA waited for a period of time (<7 days) to allow equilibrium conditions to return. Anchor QEA returned to the site on the following dates, measured depth to groundwater in the wells, and collected groundwater samples: 1 MW-3, and MW-5 December 13 and 14, 2017, for monitoring wells MW-1, MW-2, April 5, 2018, for monitoring wells MW-2, MW-5, and MW-6 Quality control samples were collected during the December 2017 and April 2018 sampling event and included a duplicate sample, trip blank, and equipment blank. Low-flow sampling techniques were utilized to reduce turbidity in groundwater samples. A peristaltic pump was used to purge and collect samples from monitoring wells MW-2, MW-3, and MW-6. , A 1 On January 12, 2018, Anchor QEA returned to the site to resample monitoring well MW-2 for nitrate-nitrite due to laboratory mishandling. Notice of Violation and Notice of Intent to Enforce Response5 June 2018 bladder pump was used to purge and collect samples from monitoring wells MW-1 and MW-5 due to deeper water table depths Prior to purging, groundwater levels were measured using a water level meter. Groundwater samples were collected after field parameters had stabilized (Appendix E). Field parameters (pH, temperature, dissolved oxygen, specific conductance, and oxidation reduction potential \[ORP\]) were measured approximately every 3 minutes with a calibrated YSI 556 multiparameter water quality meter. Turbidity was also measured using a turbidity meter. Parameters were considered stabilized after three consecutive readings were within the following ranges: pH: ±0.1 unit Specific conductivity: ±3% Temperature, dissolved oxygen, and turbidity: ±10% ORP: ±10 millivolts Turbidity: <10 NTUs (if practical) The final field parameter readings for each collected sample are presented in Table 2. Samples were transferred to laboratory-provided sample containers and placed in a cooler on ice for delivery to the laboratory. Anchor QEA had Pace Analytical Services, LLC (Pace), a North Carolina-certified laboratory, analyze the groundwater samples collected on December 13 and 14, 2017, and April 5, 2018, for the constituents listed in Table 3. The groundwater depth measurements, summarized in Table 4, were used to develop groundwater elevation map for the site (Figure 4). Groundwater elevation contours are approximate. They were developed based on ground surface elevations provided by the North Carolina Flood Plain Mapping 2 project, measuring the aboveground stickup of the monitoring well casing and calculating the top- of-casing elevation for each well. The groundwater elevation was then determined by subtracting the depth to groundwater from the top-of-casing elevation. Depth to groundwater was measured each time a monitoring well was sampled. Figure 4 provides the estimated groundwater elevation for the data collected in December 2017. 2.3Treatment Pond Sampling To supplement the work performed by James & James to assess ammonia in the treatment pond, Anchor QEA collected samples from the treatment pond as follows (the locations of these samples are shown in Figure 3): December 21, 2017 2 The North Carolina Flood Plain Mapping project provided light detection and ranging data (LiDAR) for the state, resulting in a high- resolution elevation model. The data are provided through NC OneMap’s 2-Foot Statewide Elevation Contour dataset. Notice of Violation and Notice of Intent to Enforce Response6 June 2018 0.5 foot below pond surface: Pond 1-A, Pond 2-A, and Pond 3-A 3 feet below pond surface: Pond 1-B, Pond 2-B, and Pond 3-B At pond surface: Pond-FC April 5, 2018 At pond surface: Pond-1 Samples were collected with a peristaltic pump, polyethylene tubing (new tubing for each sample), a weight, and a guide line. The guide line was used to position the two lengths of tubing in the center of the treatment pond, and a weight was used to position the openings of each tube near the bottom of the pond or just below the surface, depending on whether it was a deep or shallow sample. The fecal coliform sample and the sample collected on April 5, 2018, was collected using a dedicated plastic container that was properly cleaned in between collected samples. The samples were transferred to laboratory-provided containers and placed in a cooler on ice for delivery to the laboratory. Field parameters were also measured for these sample locations and are included in Table 2. Anchor QEA had Pace analyze the treatment pond samples collected in December 2017 and April 2018 for the constituents shown in Table 3. 2.4Ditch Water Sampling Anchor QEA collected samples from the ditch that lies between the treatment pond and the site’s septic drain field as follows (the locations of these samples are shown in the attached Figure 3): December 21, 2017 North end of the ditch: D-1 South end of the ditch: D-2 April 26, 2018 North end of the ditch: D-1.2 South end of the ditch: D-2.2 Ditch at the property boundary: D-3 Downstream of the breach in the ditch bank: D-4 Samples were collected in the same manner as the treatment pond samples and then were transferred to laboratory-provided containers and placed in a cooler on ice for delivery to the laboratory. Field parameters were measured for these sample locations and are provided in Table 2. Anchor QEA had Pace analyze the ditch water samples for the constituents shown in Table 3. Notice of Violation and Notice of Intent to Enforce Response7 June 2018 2.5Influent and EffluentSampling Influent and effluent to the treatment pond were sampled at the following locations: A sample of the influent to the treatment pond (INF) was collected on December 21, 2017. The sample was collected prior to discharge into the treatment pond, where the wastewater discharge exits the facility (Figure 3). A sample of the effluent from the treatment pond (EFF) was obtained on December 21, 2017, by collecting effluent in the spray field during active spraying. The sample was collected midway up the hill as shown in Figure 3. This sample represents the effluent that infiltrates the spray field. Anchor QEA had Pace analyze the influent and effluent samples for the constituents shown in Table 3. 2.6Limited Site Receptor Survey As required in the NOV-NIE, Anchor QEA performed a limited site receptor survey to identify potential receptors located within 1,500 feet of the site. In December 2017 and January 2018, Anchor QEA contacted the Henderson County Department of Public Health and reviewed septic system permits (which often identify the location of a supply wells relative to a septic system) and new water supply well permits. Anchor QEA also contacted the City of Hendersonville Water and Sewer Authority and provided a list of addresses for the adjacent property owners and asked to verify the addresses that were connected to a municipal water supply. Anchor QEA then compiled this data into a GIS database and created a map identifying known well locations. On January 22, 2018, Anchor QEA performed a drive-by assessment of the properties within 1,500 feet of the site to verify whether a well was present and then updated its GIS database accordingly. Figure 5 provides the results of the limited site receptor survey performed by Anchor QEA in December 2017 and January 2018. 2.7SamplingResults December 2017 and April 2018 sample analytical results are summarized in the following subsections. Field parameter data collected during these events is provided in Table 2, and the analytical results are summarized in Tables 5 and 6. Figures 6 and 7 display the sample analytical results on a map of the site features. Laboratory analytical reports are included in Appendix F. There were many analytes that were analyzed as part of this investigation, and these are provided in Tables 4 and 5; however, the field parameter and analytical results discussed in the following sections provide insight into the 2L groundwater violations observed at monitoring well MW-2. 2.7.1Field Parameter Data Field parameters were measured for each sample collected during the December 2017 and April 2018 sampling events. The field parameter data for the groundwater samples varies significantly Notice of Violation and Notice of Intent to Enforce Response8 June 2018 between monitoring wells (Table 2). The parameters with the most significant differences are summarized as follows: Specific conductance measures the potential conductance for a water sample. Higher specific conductance measurements indicate a greater concentration of dissolved constituents. Specific conductivity measurements of groundwater from monitoring wells MW-2 and MW-6 were higher than those from monitoring wells MW-1, MW-3, and MW-5. Dissolved oxygen measurements indicate the concentration of the oxygen in a water sample. Dissolved oxygen measurement of groundwater from monitoring wells MW-2 and MW-6 are less than those from monitoring wells MW-1, MW-3, and MW-5. ORP measures the tendency for chemical constituents to acquire electrons and thereby be reduced. High ORP values indicate aerobic conditions, and low ORP values indicate anaerobic conditions. ORP measurements from monitoring wells MW-2 and MW-6 were much lower than those observed from monitoring wells MW-1, MW-3, and MW-5. 2.7.2Groundwater Sample Results Table 5 presents the groundwater analytical results and a summary of the groundwater results in relation to the 2L groundwater standards as follows: Monitoring well MW-2 – Analytical results confirmed detections in MW-2 of ammonia, iron, and manganese at concentrations that exceed the 2L groundwater standards. MW-2 also had low detections of volatile organic compounds that were below the 2L groundwater standards. Monitoring well MW-6 – Results for the sample collected from the new monitoring well, MW-6, indicated detections of nitrate, iron, and manganese that exceed their respective 2L groundwater standard. Ammonia was also detected at concentrations that were just below the 2L groundwater standard. Monitoring wells MW-1, MW-2, and MW-5 – pH (refer to Table 2) was outside of the range provided in the 2L groundwater standard. Monitoring well MW-3 – Results for this monitoring well did not exceed any 2L groundwater standards. 2.7.3Treatment Pond, Influent and Effluent, and Ditch Sample Results The treatment pond was sampled by James & James in September 2017 at 12 locations from the bottom of the treatment pond. The samples were analyzed for ammonia and pH. The ammonia concentrations ranged from 194 micrograms per liter (µg/L) to 6,990 µg/L, and pH ranged from 2.0 to 2.7. The treatment pond, influent, and effluent samples collected by Anchor QEA had detections for the following constituents: nitrogen compounds (non-detect for ammonia), iron, manganese, sodium, Notice of Violation and Notice of Intent to Enforce Response9 June 2018 calcium, magnesium, potassium, phosphorus, chloride, total dissolved solids, total suspended solids, biological oxygen demand, and chemical oxygen demand (Table 6). As the treatment pond is designed and permitted to accept untreated influent and treat it to levels that are acceptable for land application, these detections are expected and will fluctuate dependent on the nature of the influent conveyed to the treatment pond. Likewise, the effluent pumped from the treatment pond and sprayed onto the field had similar constituent detections as the treatment pond samples. Stormwater runoff from precipitation events may mobilize accumulated constituents applied to the spray fields and convey these constituents to the drainage ditch that lies between the treatment pond and the septic drain field. The samples of the water collected from the ditch also exhibit similar constituent detections as the treatment pond and effluent, with the exception that the ditch water had concentrations of ammonia (Table 6). 2.8Comparison of Results Noted differences in constituent concentrations among the treatment pond samples, the influent and effluent samples, the ditch samples, and groundwater samples include the following: Ammonia Ammonia was not detected above the method detection limit of 50 µg/L in the treatment pond, influent, or effluent samples collected by Anchor QEA, suggesting that the pond is maintained in an aerobic state and that aeration is effectively treating the wastewater. Ammonia was detected in monitoring wells MW-2 and MW-6 and Ditch Samples D-1, D-2, and D-4. Nitrate was detected at concentrations less than the 2L groundwater standard at groundwater monitoring wells MW-1, MW-2, MW-3, and MW-5 and was not detected above the method detection limit of 50 µg/L or 10 µg/L for the treatment pond samples, the ditch samples, and groundwater monitoring well MW-6. Phosphorus was detected at estimated concentrations in the groundwater samples from monitoring wells MW-1, MW-2, MW-3, and MW-5 (and at less than 25 µg/L at MW-6) and is generally up to 2 orders of magnitude higher in the influent, effluent, and treatment pond samples and 1 to 2 orders of magnitude higher in the ditch water samples compared to the well samples. On average, pH in the treatment pond and effluent samples was about 3.8. The pH was generally higher for the influent, groundwater, and ditch water samples. Notice of Violation and Notice of Intent to Enforce Response10 June 2018 Alkalinity was measured in samples collected from the treatment pond, the ditch, and monitoring wells MW-2, MW-5, and MW-6. Alkalinity was highest in the sample from monitoring well MW-2 and lowest in the sample from monitoring well MW-6. Volatile organic compounds (VOCs) were only detected in monitoring well MW-2 and at concentrations below the 2L groundwater standards. In addition to comparing the results of samples collected from different locations, Anchor QEA compared the change in pH over time in samples collected from monitoring wells MW-1 (the former background well), MW-3, and MW-2. These data suggest an increasing trend for pH in monitoring well MW-2 and a steady trend for pH in monitoring wells MW-1 and MW-3 (Figure 8). Notice of Violation and Notice of Intent to Enforce Response11 June 2018 3Receptor Survey Results The results of the receptor survey are presented in Figure 5, whichshows the locations of identified receptors along with the owner name and address. Anchor QEA identified several private water supply wells near the site; however, most wells are in an upgradient or crossgradient direction from the site. One water supply well was identified adjacent to the site toward the southwest. This water supply well is located at approximately 580 feet from the treatment pond and across the western tributary to Wolfpen Creek. Notice of Violation and Notice of Intent to Enforce Response12 June 2018 4Hydrogeologic Setting The AllJuice facility is positioned on top of a northwest-trending topographic ridge that is bound the northeast and southwest by small tributaries of Wolfpen Creek. The treatment pond is positioned on the southwestern side of the ridge, and the spray fields are upgradient from the treatment pond. The wastewater effluent from the treatment pond is spray-applied to the spray fields and infiltrates into the soils and ultimately to the groundwater table. The ridge, as anticipated, creates a groundwater divide. Anchor QEA’s depth-to-groundwater measurements indicate a relatively deep groundwater table underneath the spray fields (up to 50 feet belowground at monitoring well MW-5) and a shallower groundwater table in the vicinity of the treatment pond (about 18 feet belowground at monitoring well MW-2). Anchor QEA’s interpretation of the groundwater elevation contours for the site are provided in Figure 4 and show the interpreted groundwater flow directions to the southwest and northeast. Anchor QEA also estimated groundwater flow velocity. Groundwater flow velocity is calculated by multiplying the horizontal hydraulic conductivity with the horizontal hydraulic gradient and dividing the product by the effective porosity. To estimate the groundwater flow velocity, Anchor QEA used the following parameters: Horizontal hydraulic gradient, based on the groundwater flow lines i and i shown on Figure 12 4. Horizontal hydraulic conductivity, based on hydraulic conductivity values reported in the Bent Creek Hydrogeological Investigation Report (North Carolina Division of Water Quality, 2011) of 0.2 to 3 feet per day. To refine these values, Anchor QEA referred to recent work performed at another site located in Transylvania County and in a similar geologic setting. At this site, K values ranged from 0.5 to 1.62 feet per day. In Anchor QEA’s opinion, these values seem more reasonable. Effective porosity, assumed to be 0.3 based on observation of fine sand and silt observed in boreholes advanced on site during the installation of monitoring wells MW-5 and MW-6. Anchor QEA estimates the average groundwater flow velocity at the site to be between 10.4 and 49.5 feet per year. In areas of the site where the hydraulic gradient is steeper, the groundwater flow velocity will be faster; in locations near the septic drain field and treatment pond, the gradient is less steep, so the groundwater velocity in this area will be slower. Notice of Violation and Notice of Intent to Enforce Response13 June 2018 5Discussion One of the goals of this investigation was to determine the cause of the 2L groundwater standard violations in samples collected from monitoring well MW-2. This section of the report describes the collected data and presents lines of evidence that suggest that the treatment pond is not the primary source for the 2L groundwater standard violations in samples collected from monitoring well MW-2. To assist in this discussion, a conceptual cross section was developed that identifies the treatment system flow diagram and potential inputs to the groundwater at the site (Figure 9). The cross section shows the positions of monitoring well MW-2, the treatment pond, the drainage ditch, monitoring well MW-6, and the septic drain field. The cross section is oriented east to west and parallels the interpreted groundwater flow path from the septic drain field to monitoring well MW-2. Monitoring Well Locations Relative to Potential Source Areas Monitoring well MW-2 has been used as a compliance monitoring well since the site was permitted for land application of treated wastewater. The current NOV-NIE was issued based on iron, manganese, and ammonia concentrations in sampled groundwater from monitoring well MW-2 that exceed the 2L groundwater standards. Monitoring well MW-2 is positioned downgradient from the treatment pond, and the ditch is located between the treatment pond and the septic drain field (Figure 4 and Figure 9). Monitoring wells MW- 1, MW-3, and MW-5 are positioned to the west, east, and north of the spray application field. MW-5 is a new background monitoring well that has been installed to replace the former background monitoring well, MW-1. Monitoring wells MW-1 and MW-3 are located in positions where groundwater flow from the spray applications areas will migrate past these wells, and they provide opportunity to evaluate the performance of the spray application area. The newest well, MW-6, is located on the western side of a groundwater divide and is between the septic drain field and the ditch, both of which are upgradient of the treatment pond. Groundwater elevation data suggest that a flow path from the spray irrigation field to monitoring well MW-2 is unlikely to exist (Figure 4). Therefore, the spray irrigation field is an unlikely source for the 2L groundwater standard violations observed in samples collected from monitoring well MW-2. A direct groundwater flow path exists from the septic drain field past monitoring well MW-6 and past the ditch and treatment pond to monitoring well MW-2. This flow path is depicted in Figure 9. Monitoring well MW-2 is screened approximately 25 feet below the water table, downgradient of the treatment pond, and monitoring well MW-6 is screened at the top of the water table, downgradient and adjacent to the septic drain field. The geochemistry between these two locations is distinct from the other monitoring wells on site and indicates impacts from the failed septic system. Both monitoring wells MW-2 and MW-6 have low dissolved oxygen and high dissolved solids compared to the other monitoring wells. The alkalinity in monitoring well MW-2 is more than 20 times that Notice of Violation and Notice of Intent to Enforce Response14 June 2018 observed in samples from monitoring well MW-6, suggesting that denitrification is not occurring in monitoring well MW-2. The high concentrations of ammonia, iron and manganese in monitoring well MW-2 suggest the following: 1.Ammonia is not fully undergoing denitrification and concentrations of ammonia are entering the groundwater table and migrating downstream to monitoring well MW-2. 2.Denitrifying bacteria are active in some areas of the ammonia plume and are obtaining oxygen through reduction of manganese and iron oxides, resulting in elevated concentrations of these elements that are migrating downstream to monitoring well MW-2. Ditch East of the Treatment Pond Stormwater runoff from the spray irrigation fields is conveyed to a tributary of Wolfpen Creek by the ditch located to the east of the treatment pond. The ditch runs generally north to south and has a shallow gradient, which results in accumulation of stagnant water in some locations. It is possible that stormwater runoff mixes with sprayed effluent and carries wastewater constituents to the ditch. Additionally, Anchor QEA identified a breach in the ditch’s eastern embankment, located near the northern end of the septic drain field (Figure 2). This discovery was communicated to AllJuice in November 2017. AllJuice had the septic system evaluated and determined that it was not functioning correctly. Since December 2017, AllJuice has been removing its septic waste by a pump-and-haul service and has contracted a septic installation company to assist with the installation of a new septic system. The ditch represents a potential source for the concentrations observed in monitoring well MW-2. 3 Samples collected from the ditch confirmed the presence of ammonia (range of detections 58 J to 4,100 µg/L). If the failed septic system contributed to the ammonia detected in the samples collected from the ditch, then the ditch may have contributed to the ammonia concentrations detected in samples collected from monitoring well MW-2. Treatment Pond The treatment pond is reportedly unlined; however, historical ammonia concentrations analyzed from effluent compliance samples suggest that ammonia has been well managed by the treatment pond (Figure 10). The best historical record of the potential ammonia concentrations in the pond is from the historical compliance data for the pond effluent. There was a period from 2006 to 2011 where effluent concentrations of ammonia where elevated. Since 2011, ammonia effluent concentrations have been below laboratory reporting limits or have ranged upwards of 10 milligrams 3 A “J” value in a laboratory analytical report indicates that the result is estimated because it was detected at a concentration that lies between the laboratory’s method detection limit and it practical quantitation limit. Notice of Violation and Notice of Intent to Enforce Response15 June 2018 per liter (or 10,000 µg/L, to compare to the results in Tables 5 and 6). These are similar to the non- detect results obtained through analysis of Anchor QEA’s treatment pond samples. As an unlined pond, it is anticipated that it is leaky; however, given the high concentration of ammonia observed in monitoring well MW-2, it seems unlikely that the source of the ammonia is the treatment pond. Even if the pond leaked ammonia during the period from 2006 to 2011, when effluent concentrations were high, the impacts from the potential leak would most likely have migrated past monitoring well MW-2 based on the estimated groundwater flow velocities provided in Figure 4. Factoring in natural attenuation effects (such as adsorption, dispersion, and dissolution), it is unlikely that the treatment pond is causing the elevated concentrations at monitoring well MW-2. Septic System After Anchor QEA observed the breach in the drainage ditch embankment, an investigation of the septic system was performed. Anchor QEA discovered that the septic system required repair in 1999 due to poor performance. Part of the repair included burying the drain lines in the leach field deeper. In a properly functioning septic system, organic nitrogen excreted by humans flows in wastewater into the septic tank. The organic nitrogen in the wastewater is converted to ammonia by micro- organisms in the septic tank. Ammonia is the primary form of nitrogen in wastewater leaving the septic tank (Seiler 1996; EPA 2002). In the presence of oxygen, indigenous bacteria in the unsaturated zone will transform the ammonia in the wastewater into nitrate. Anchor QEA believes that burying the drain lines deeper reduced the availability of oxygen, which resulted in ammonia not being reduced to nitrite and nitrate. Ammonia in the wastewater likely passed through the unsaturated zone and infiltrated into the groundwater causing ammonia to exceed the 2L groundwater standards. The lack of oxygen beneath the septic drain lines may also promote denitrifying bacteria to begin using manganese and iron oxides for their oxygen source during the denitrification process, thus mobilizing manganese and iron in the process. Manganese is highest in monitoring well MW-6, suggesting that denitrification is occurring in this location through the respiration of manganese oxides. The order of reactions for respiration of denitrifying microbes is aerobic respiration, denitrification, manganese reduction, iron reduction, then sulfate reduction (Seiler 1996). Lines of Evidence to Suggest the Septic Field Source is the Primary Contributor to the 2L Groundwater Standard Violations in Groundwater from Monitoring Well MW-2 1.Monitoring well MW-2 had high concentrations of ammonia (28,800 µg/L), iron (640 to 16,700 µg/L), and manganese (8,460 µg/L). 2.Based on recently collected data, ammonia concentrations in pond samples are not typically greater than 7,000 µg/L; iron concentrations are generally less than 4,500 µg/L, and manganese concentrations are generally less than 57 µg/L. Notice of Violation and Notice of Intent to Enforce Response16 June 2018 3.Historical effluent data from 2001 to 2017 suggests that the aeration of the pond appropriately treats ammonia, reducing its concentration to less than laboratory reporting limits or trace amounts. 4.Historical groundwater monitoring data indicates that VOCs have been observed in monitoring well MW-2 in the past, and recent samples show VOCs to be present in trace amounts less than the 2L groundwater standards. This suggests potential influence from the septic system, since the facility sinks and the trace amounts of VOCs present in household chemicals placed into them drain to the septic system. 5.Ammonia concentrations in the downstream ditch sample collected in December 2017 were about 4,500 µg/L and non-detect in upstream ditch samples, suggesting that septic effluent may have affected the water in the ditch. 6.Ammonia concentrations in the April 2018 downstream ditch sample and the sample collected at the ditch embankment breach were 190 and 110 µg/L, respectively. This represents greater than an order of magnitude reduction since December 2017, when the septic system wastewater began to be managed by pump and haul to off-site treatment. 7.Dissolved oxygen, pH, phosphorus, and ammonia are significantly different in the pond samples as compared to samples from monitoring well MW-2. If the pond was very leaky, constituent concentrations would likely be similar. 8.Other site monitoring wells show influence from spray application of wastewater, but samples from those wells do not have ammonia concentrations like monitoring well MW-2. 9.The newly installed monitoring well, MW-6, located adjacent to the downgradient side of the septic drain field, was sampled in April 2018, and concentrations of ammonia were detected. Septic systems are designed to convert ammonia to nitrogen through biologic activity, and if they are not functioning correctly, ammonia will go untreated and potentially impact groundwater. 10.Pure ammonia is caustic, with pH of 11. Continued input of ammonia into the groundwater system may increase groundwater pH; the pH in samples from monitoring well MW-2 have been increasing for many years, and the pH in samples from monitoring well MW-1, which is upgradient of the pond, has remained relatively the same over the same time period. Notice of Violation and Notice of Intent to Enforce Response17 June 2018 6Conclusions and Recommendations The DEQ requested that AllJuice assess the cause, significance, and extent of the violation of the 2L groundwater standards and submit the results of the investigation along with a plan and proposed schedule for corrective action. 6.1Cause Based on the data presented in this report, Anchor QEA believes that the 2L groundwater standard violations observed in the samples collected from monitoring well MW-2 are due to an improperly functioning septic system. 6.2Significance and Extent The source area for the elevated concentrations has been identified as a failed septic drain field, which lies on a groundwater migration pathway flowing from east to west. By applying an understanding of groundwater movement, Anchor QEA surmises that the extent of impacts to groundwater are very likely limited to the area between the septic drain field (area of recharge) and the tributary of Wolfpen Creek (area of discharge). 6.3Corrective Action AllJuice is having the on-site septic system drain field replaced (anticipated completion is late August, 2018) and has mitigated the potential impact of the septic system on the groundwater resource by pumping and hauling its sanitary wastewater to an off-site sanitary wastewater facility. Since taking these actions, concentrations of ammonia observed in ditch water samples have reduced significantly. Furthermore, the nearest water supply well is more than 500 feet from monitoring well MW-2 and separated from the septic system source area by the tributary of Wolfpen Creek. Natural attenuation factors will reduce the impacts quickly in the downgradient direction of the septic system now that the drain field is being replaced. In the opinion of Anchor QEA, corrective action is likely complete. Additional monitoring wells are not required to further define the extent. Groundwater samples should be collected from monitoring wells MW-2 and MW-6 routinely as required by the permit to monitor the change in groundwater conditions now that the septic system has been replaced. Anchor QEA recommends the following actions: 1.Include the collection of groundwater samples from monitoring wells MW-5 and MW-6 with the sampling schedule defined in the 2017 permit for monitoring wells MW-1, MW-2, and MW-3. During low-flow sampling, do not collect groundwater samples for analysis until the groundwater extracted from the wells has a turbidity of 10 NTUs and field parameters (temperature, dissolved oxygen, ORP, pH, and specific conductivity) have stabilized.

The pipe inspection was performed on February 25, 2020; its purpose was to evaluate the source for fecal coliform found in the wastewater treatment system’s irrigation holding pond. The off-site stream assessment was performed on June 23, 2020. Anchor QEA collected off-site stream data to evaluate potential off-site impacts from groundwater with elevated ammonia and metal concentrations. This work was completed to fulfill two of the recommendations listed in the Corrective Action Assessment Report, which was submitted to the North Carolina Department of Environmental Quality (DEQ) in April 2020 in response to DEQ’s March 5, 2019 letter regarding: Review of the Notice of Violation and Notice of Intent to Enforce Response Report and Required Corrective Action Measures (DEQ 2019). The information below outlines the process and findings of this work. Pipe Inspection AllJuice contracted directly with Summey Plumbing to perform an inspection of the pipe that conveys wastewater from the facility to the irrigation pond. A pipe camera was routed through the pipe and recorded its integrity. Observation of the video indicated a pipe repair zone at the approximate vicinity of the former septic tank. The video shows a section of green PVC pipe that has been damaged with an outer black corrugated plastic pipe (Figure 1).

The location of the repaired pipe is shown in Figure 2. Surface Water Sampling The off-site tributary to Wolfpen Creekreceives stormwater flow from the AllJuice facility,conveyed by an incised drainage ditch. The drainage ditch discharges into the tributary upstream from a small farm pond (Figure 2). The triburtary is dammed in two locations, forming two farm ponds. The upstream pond, which is surrounded by an orchard, appears to be located near the headwater spring that feeds into the tributary. Approximately 320 feet downstream from this pond is the outfall for the drainage ditch conveying stormwater from the AllJuice facility. Approximately 90 feet downstream from the outfall is a second farm pond, which discharges into the tributary and flows northwest for approximately 1,700 feet to the confluence with Wolfpen Creek. The tributary transects property owned by Michael Brown, part of which is an active cattle farm. The tributary to Wolfpen Creek is the groundwater discharge zone for the valley it defines. The goal of the surface water sampling program is to evaluate the potential impacts to surface water quality from groundwater migrating from the western boundary of the AllJuice facility. Anchor QEA referred to the groundwater potentiometric surface map, provided in the CAAR, to identify surface water sampling locations. Three locations were selected from areas of the tributary that were more likely to be under the influence of groundwater flow contributions from the AllJuice facility based on potential groundwater flow lines. Three other locations were selected from the upstream tributary reach that connects the two farm ponds; one sample was collected downstream of the stormwater ditch outfall and two samples were collected upstream of the stormwater ditch outfall. A final sample was collected from the drainage ditch prior to where it discharges to the tributary. See Figure 2 for the sample locations. With the assistance of Brett Laverty with DEQ, Anchor QEA contacted the adjacent property owner, Mr. Michael Brown, and obtained permission to enter his property to collect the surface water samples. On the afternoon of June 23, 2020, Anchor QEA staff mobilized to site to collect six samples (SS-1 to SS-6) from the Brown property and one sample from the ditch located on AllJuice property (DITCH-6). All off-site sample locations were collected as grab samples from the flowing tributary. DITCH-6, the on-site location, was collected from a stagnant pool of water within the ditch because the ditch was not flowing at the time of collection. Parameters were collected for each sample using a YSI Pro Plus Multiparameter instrument. All grab samples were placed in laboratory bottles, immediately stored on ice, and dropped off at Pace Analytical, a North Carolina certified lab, later that day for analysis. A field duplicate sample was collected at location SS-2 to serve as a quality control sample. All samples were submitted for September 9, 2020 Page 3 analysis of ammonia, Total Kjeldahl Nitrogen, nitrate/nitrite, phosphorus, total alkalinity, sulfate, chloride, calcium, iron, magnesium, manganese, potassium, sodium and fecal coliform. Analytical results and field parameters are summarized in Table 1. Field forms and an equipment calibration log are included in Attachment 1. Analysis Summary The stream samples have been grouped into two groups. Group 1 includes sample locations that are positioned upgradient of the potential discharge of groundwater from the AllJuice facility (SS-1, SS-2, and SS-3). Group 2 includes sample locations that are positioned in the zone of potential groundwater discharge from the AllJuice facility (SS-4, SS-5, and SS-6). In general, the data from Group 1 and Group 2 are very similar. The constituents that show an increase in concentration from Group 1 to Group 2 include the following: total alkalinity, sulfate, chloride, calcium, iron, manganese, phosphorus, sodium, and fecal coliform. Ammonia and nitrate/nitrite are more concentrated in the Group 1 (upstream) samples than in the Group 2 (downstream) samples. Groundwater at the AllJuice facility exceeds 2L standards, defined in 15A NCAC 2L (DEQ 2018), for ammonia, iron, and manganese. The June 2019 sampling event data (reported in the CAAR) is included in Table 1 for the western boundary compliance monitoring wells (MW-2, MW-7, and MW- 9) at the AllJuice facility. Figure 3 displays Stiff diagrams (also shown mapped on Figure 2) that show the milliequivalent concentrations of major cation and anion groups, which can be used to evaluate the change in water quality as water migrates from areas of recharge to discharge. Groundwater data from June 2019 along with the June 2020 stream sample data were used to create the Stiff diagrams. Based on the collected data, the major ions with the highest concentrations in groundwater at the AllJuice facility are alkalinity (bicarbonate), sodium (combined with potassium on the Stiff diagram), and chloride. These constituents are most concentrated in the ditch sample, in monitoring well MW-2, and to a lesser extent in MW-9 (Figure 3). The Stiff diagrams show that alkalinity in stream water is slightly elevated in the Group 2 samples compared to the Group 1 samples. This difference in alkalinity concentrations may indicate an influence from the groundwater source; however, this argument is weakened by the lack of groundwater influence on sodium, potassium, and chloride concentrations. These constituents are more elevated in the groundwater samples and show little variation from the upstream (Group 1) samples to the downstream (Group 2) samples. Group 2 stream samples represent discharge locations for groundwater migrating from the western boundary of the AllJuice facility. As such, Group 2 stream samples do not show a significant major ion geochemical influence from groundwater originating from the AllJuice facility. September 9, 2020 Page 4 The groundwater constituents that exceed the 2L standards at the AllJuice facility (ammonia, iron, and manganese) are shown below with the ranges detected in Group 1 and Group 2 samples: Iron Manganese Ammonia (µg/L) (µg/L) (mg/L) Group or Well Group 1(upstream) 810 to 1,180132 to 154 0.11 to 0.14 Group 2 (downstream) 1,330 to 1,510 256 to 482 0.070 U to 0.097 J MW-2 7,280 9,080 29.1 MW-7133 300 0.050 U MW-9 455 40.90.050 U Notes: Bold indicates a 2L Groundwater Standard is exceeded. µg/L: micrograms per liter mg/L: milligrams per liter J: estimated value U: non detected above method detection limit Based on these observations, metal concentrations from MW-2 may be influencing the tributary chemistry; however, ammonia concentrations from MW-2 are not. The sample collected from the stagnant pool of water from the drainage ditch shows similar constituent detections as past samples from the ditch; however, they appear more concentrated. This 1 may be due to evaporative effects following the last rain. Sample SS-3 was collected downstream from the drainage ditch and is very similar to the upstream concentrations in SS-1 and SS-2. Therefore, the drainage ditch sample provides an understanding of constituents that may enter the stream during significant rain events. SS-4, collected immediately downstream of the pond overflow pipe, has slightly elevated constituent concentrations compared to Group 1 samples, suggesting that input from the drainage ditch does not have a lasting influence on the pond water quality (Table 1). Conclusion The February 25, 2020, video pipe inspection identified a section of the wastewater discharge pipe that had been repaired in the past. The repaired section of pipe is located near the former septic drain field. The repaired section of pipe does not appear watertight. Anchor QEA recommends having this section of pipe repaired to prevent meteoric water from entering the wastewater pipe and introducing fecal coliform. On June 23, 2020, six stream samples were collected from locations along the tributary to Wolfpen Creek. Three samples were collected upstream (Group 1) from the zone of groundwater discharge from the property boundary. Three samples were collected (Group 2) within the zone of groundwater 1 Review of daily rain events from Henderson County (https://www.ncdc.noaa.gov/cdo- web/datasets/GHCND/stations/GHCND:USC00313976/detail) indicate that the last rain event preceding the sampling event occurred on June 19. September 9, 2020 Page 5 discharge. The stream sample results were compared to groundwater data from property boundary wells collected from June 2019. The Group 2 sample results, on the whole, displayed slightly higher concentration than the upstream Group 1 sample results. Groundwater concentrations of iron and manganese observed from well MW-2 may be influencing iron and manganese concentrations in Group 2. Ammonia is not negatively impacting the stream due to groundwater migration from the AllJuice facility.

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 A:\\Projects\\AllJuice\\2021-0323_NOV Response\\AllJuice - Response to NOV 2021-0331.docx 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 1 storage pond. 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.

The pipe is thought to have been damaged and repaired in 1999 during a septic system maintenance project. The potential for wastewater to exit the pipe and flow along bedding material to discharge into the stormwater ditch was discussed during the call. DEQ expressed the concern that a sample of water from the Ditch 6 sample location had elevated sodium concentrations, which is indicative of wastewater. DEQ also questioned the potential of this sodium concentration to be related to wastewater escaping the repaired section of pipe. Anchor QEA agreed to summarize the site information with regards to observed sodium concentrations (Figure 1). In general, sodium concentrations in sampled media are summarized below: Wastewater from the facility ranges from 16,100 to 18,500 µg/L. The wastewater in the pond and applied to the fields is more concentrated, ranging from 69,800 to 85,000 µg/L. Concentrations measured in the Ditch 6 location have ranged from a low of 7,630 µg/L to a high of 246,000 µg/L. 1 This letter is a follow up response to the March 1, 2021 Notice of Violation. The original response was submitted on March 31, 2021 (Response to Requirements of the March 1, 2021 Notice of Violation, Anchor QEA, March 31, 2021). A:\\Projects\\AllJuice\\2021-0323_NOV Response\\2021-0625-AllJuice - Sodium Concentration Summary Response to NOV 2021-0607.docx June 25, 2021 Page 2 Concentrations observed at locations between Ditch 6 and theapplication fields range from 20,900 to 53,900 µg/L. Regarding DEQ’s assertion of the potential for wastewater to be discharged from the repaired section of the wastewater pipe, Anchor QEA provides the following observations: The pipe inspection video shows the bottom half of the wastewater pipe to be undamaged in the area of the repair. Discharge through the pipe is relatively constant during production and is below the damaged portion of the pipe; therefore, a full-pipe scenario, that would result in a leak is unlikely. The anomalous sodium concentration observed at Ditch 6 is higher in concentration than any other sample collected on site and more than 10 times the concentration of the influent wastewater. Anchor QEA has not observed water flowing into the ditch at the location where the wastewater pipe spans the ditch. Groundwater measured at temporary well TW-3 on June 14, 2019, had relatively low sodium concentrations (7,420 µg/L), suggesting that the pipe is not attributing to a wastewater release to subsurface soils and ultimately to groundwater. Sampling at ditch location D-6 has occurred on three occasions o On October 21, 2019 water was flowing at the D-6 location. Sodium concentration was 13,600 µg/L o On October 31, 2019 water was flowing at the D-6 location. Sodium concentration was 7,630 µg/L o On June 23, 2020 water was stagnated at D-6 location. Sodium concentration was 246,000 µg/L During periods of flow at the Ditch 6 location, sodium results are relatively similar; however, the concentration from the stagnated pool was much more concentrated, likely due to evaporative effects. Given the anomalous concentration observed from ditch sample (D-6) collected on June 23, 2021, Anchor QEA recommends closely inspecting the wastewater pipe where it spans the ditch to observe potential flow from pipe bedding material into the ditch and resampling location Ditch-6 following a rain event. Planned improvements to the application fields, will include rerouting the wastewater pipe, to discharge plant effluent to the northern portion of the modified wastewater storage pond and the June 25, 2021 Page 3 addition of a stormwater retention pond to prevent overland flow from the application fields entering the drainage ditch. These design elements will effectively mitigate impacts from possible leakage from the repaired section of effluent piping and from stormwater flow from the application fields to off-site receiving streams. On behalf of AllJuice, Anchor QEA is requesting that the DEQ allow AllJuice to postpone the pipe repair, until construction of the storage pond modification is started. Should the DWR have questions or concerns, please do not hesitate to contact me by email or phone (828.771.0378).

The nature of the wastewater has not changed since the last permit issuance in 2017. The manufacturing process can be described as follows: 1. Juice concentrate is mixed with water within the facility manufacturing process and is bottled and packaged for distribution. 2. Wastewater is captured on the production line and floor drains and is conveyed to an outside pH neutralization sump. 3. From the sump, wastewater is conveyed underground by gravity flow to a storage pond where it is mixed and aerated. 4. Effluent from the storage pond is pump to the irrigation fields where it is applied to ground surface by sprinklers where treatment is provided by plant uptake. A more detailed description is provided on page 3 of the Corrective Action Assessment Report (Anchor QEA, April 2020). The list of chemicals used in the process for cleaning and pH control includes the following: Oakite CIP Oakite Fisan-LC55 Oakite detergent sanitizer Oakite Sanitizer 1 Oakite DZL Oakite Circhlor Plus Fisan LC Degreaser Oakite CFC Oakite Liquid Bactericide Magrabar Defoamer SPI-244 Caustic for pH control The facility utilizes clean in place technology.
