(ReUse), ERM NC, Inc. (ERM), has prepared this Water Quality Monitoring Report associated with corrective action activities conducted for the Swift Creek Coal Combustion By -Products (CCBs) Structural Fill site (CCB-0057) located along U.S. Highway 301 north of Battleboro, Nash County, North Carolina, (hereafter called the "Site" or "subject property"). Corrective actions have been implemented at the Site to address groundwater quality impacts in accordance with the Corrective Action Plan (CAP) (ERM February 27, 2015) approved by the North Carolina Department of Environmental Quality (NCDEQ) on March 12, 2015. The corrective actions were implemented in 2017 and included temporary removal of CCB materials to allow raising the floor foundation above the seasonal high groundwater table, placing the CCB materials on the raised floor in a reduced footprint, installation of a synthetic liner (cap) over the limits of the CCBs, and drainage improvements to minimize rainfall infiltration. Groundwater and surface water monitoring activities presented herein are being conducted at the Site to monitor the effectiveness of the corrective actions. The Site location is shown in Figure 1. A Site map is included as Figure 2. 1.2 Summary of Site Environmental History and Corrective Action The Site is a 25-acre property in northeast Nash County bounded by US Highway 301 to the west, Lane Swamp to the north and east and Swift Creek to the south. The area surrounding the site is comprised of sparsely populated agricultural land and partially wooded land. In December 1991, the Solid Waste Section approved a proposed plan submitted by ReUse to use CCBs as structural fill material in the development of the 25 acres as a commercial property. In September 1992, ReUse began placement of CCBs as beneficial use fill at the site. In January 2003, the last shipment of CCBs was accepted at the site. In March 2003, the site had been graded, compacted, covered with an 18-inch soil cap and planted with grass seed. In December 2003, Full Circle Solutions, Inc. purchased the business assets of ReUse Technology, Inc. including the Swift Creek Site. According to records of Full Circle Solutions, Inc., a total of approximately 134,000 tons of CCBs were placed at the Site. On November 4, 2004, the Closure Notice was forwarded to the Solid Waste Section. In August 2004, Sherrill Environmental, Inc. reported the results of groundwater monitoring at four newly installed monitoring wells (MW-1 S/MW-1 D, MW-2S/MW-2D) at the site. Lead and sulfate were detected at concentrations above the respective North Carolina 2L Groundwater Standards in the shallow groundwater on the east side of the CCB fill. In October 2004, the Solid Waste Section required an assessment by ReUse to determine the extent of the groundwater impact resulting from the placement of CCBs at the Site. In March 2006, a Comprehensive Site Assessment for the Swift Creek Project was submitted to the Solid Waste Section that included the results of an expanded groundwater and surface water assessment. In September 2006, a Compliance Order was issued by the Solid Waste Section to ReUse. In December 2006, pursuant to the Compliance Order, an Assessment Monitoring Plan and a Swift Creek Dewatering Analysis were submitted to the Solid Waste Section. The Assessment Monitoring Plan described a proposed groundwater and surface water monitoring program for the site. The Swift Creek Dewatering Analysis described a proposed dewatering subsurface drain along the western boundary of the fill along US Highway 301 to remove water from the coal ash fill and lower the local groundwater table to provide a required minimum 1-foot vertical separation between coal ash and seasonal high groundwater elevations. The Assessment Monitoring Plan was approved by the Solid Waste Section in February 2007. The Swift Creek Dewatering Analysis was conditionally approved by the Solid Waste Section in July 2007 based on the performance of the proposed dewatering plan. www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 1 WATER QUALITY MONITORING REPORT— MARCH 2O20 INTRODUCTION AND SITE HISTORY Battleboro, Nash County In January 2008, a dewatering subsurface drain was installed consisting of a 6-inch PVC drain pipe along the western boundary of the fill along US Highway 301. The drain was designed to lower the local groundwater table to provide a required minimum 1-foot vertical separation between coal ash and seasonal high groundwater elevations. Groundwater collected in the pipe was transmitted by gravity flow to an outfall box located at the north end of the site at Lane Swamp. The groundwater and surface water monitoring program was initiated at the site in October 2007 in accordance with the Assessment Monitoring Plan. The program consisted of semi-annual sampling and laboratory analytical testing for metals and sulfates at eight (8) groundwater monitoring well locations and three (3) surface water monitoring locations. Groundwater levels were also measured in the monitoring wells and piezometers in order to evaluate ground water flow direction and determine water levels relative to the CCB fill. The reported results of the groundwater monitoring from 2007 to 2014 confirmed groundwater quality impacts including concentrations of sulfate, arsenic and lead at levels above the respective North Carolina 2L groundwater standards. The monitoring reported no impacts to surface water quality in Lane Swamp or Swift Creek adjacent to the facility. The Division of Waste Management issued a "Warning Notice" to Full Circle Solutions and ReUse dated May 16, 2014. The notice stated that the required groundwater vertical separation between filled CCBs and seasonal high groundwater elevations had not been achieved and exceedances of the North Carolina 2L groundwater standards had been routinely reported. As a result, a "Groundwater Corrective Action Application" was required to be submitted for approval. On behalf of Full Circle Solutions and ReUse, ERM NC, Inc. (ERM) submitted a Corrective Action Application to the Division of Waste Management dated October 16, 2014 for approval. The Corrective Action Application proposed the construction of a synthetic liner (cap) and drainage improvements as corrective actions to significantly reduce or eliminate rainfall infiltration and leachate generation from the beneficial fill. Two contingency corrective actions also were identified. The Division issued approval in December 2014 and requested the submittal of a detailed Corrective Action Plan (CAP) to the Solid Waste Section. The Corrective Action Plan was submitted in February 2015 and approved by the NCDEQ Solid Waste Section in March 2015. The Corrective Action Plan was designed to raise existing CCBs to above historically high groundwater levels to prevent the leaching of contaminants of concern from the existing CCBs. The CAP included the installation of a protective liner system, cover soil layer, and drainage outlets to prevent infiltration of precipitation into the CCBs to assist in the prevention of leaching. The footprint of the limits of ash was condensed from approximately 10 acres to 5 acres reducing the effective infiltration area. Implementation of the Corrective Action Plan was delayed approximately 1 year in 2015- 2016 due to a North Carolina Department of Transportation (NCDOT) project to realign US Highway 301 along with bridge replacements across Swift Creek. The corrective measures began on April 24, 2017 and were completed on January 12, 2018. In June 2018, two new monitor wells, MW-5RS and MW-5RD, were installed as replacements for former upgradient wells MW-5S and MW-5D which were abandoned in 2015 by the NCDOT as part of the Highway 301 realignment project. The new wells were located hydraulically upgradient (west) of the Site on the west side of Highway 301 (see Figure 2) to monitor background water quality in the surficial aquifer (MW-5RS) and deep aquifer (MW-5RD) zones. The monitor wells were installed under an NCDOT right- of-way encroachment agreement (E-0420981800025). In accordance with the CAP, a performance monitoring and reporting plan was implemented in 2018 to monitor the effectiveness of the corrective action. The elements of the performance monitoring plan include: ■ Semi-annual groundwater and surface water monitoring and reporting, www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 2 WATER QUALITY MONITORING REPORT — MARCH 2O20 CONCEPTUAL SITE MODEL Battleboro, Nash County ■ Quarterly inspection and reporting of the Site for cap structural integrity, erosion control, proper drainage, etc., and ■ Corrective Action Effectiveness Reports prepared every five years to evaluate and document a reduction in contaminant concentrations in groundwater and a stable or decreasing plume extent. 2. CONCEPTUAL SITE MODEL 2.1 Hydrogeology Based on the corrective action and monitoring work by ERM as well as previous site investigation activities performed by others, the following updated conceptual site model has been developed. The Site is located in the Coastal Plain physiographic province of North Carolina. The site surficial geology consists of alluvial terrace deposits consisting of layers and mixtures of silts, clay, sands and gravels. The alluvial deposits at the site range in thickness from approximately 8 to 16 feet. The shallow ground water at the site occurs in the alluvial deposits and is referred to as the surficial or alluvial aquifer. The alluvial aquifer sands are of low to moderate permeability (average hydraulic conductivity 0.67 feet/day). Within the alluvial aquifer zone, a yellowish -brown clay layer was encountered in the majority of the borings for monitoring wells and piezometers installed at the site. The clay layer of the alluvial aquifer at the site is approximately 1 to 4 feet thick and has a low permeability (average hydraulic conductivity 0.002 feet/day). The clayey layer behaves as a confining layer or perching layer, which appears to limit the vertical migration of contaminants at the site. On the west (upgradient) edge of the site, the clay layer was reported absent in the borings for former wells MW-5S, MW-51D, P-23 and P-24. The alluvial deposits at the site are underlain by the Yorktown Formation, a regionally extensive marine deposit. At the site, the upper Yorktown Formation, consisting typically of greenish -gray, clayey, silty, Shelly, very fine sands, is encountered from approximately 13 feet to the maximum depth of investigation of 35 feet, and has a low permeability (average of 0.002 feet per day). No groundwater quality impacts have been detected in monitoring wells completed in the deeper Yorktown aquifer zone. The general groundwater flow pattern at the site is controlled largely by two groundwater discharge features: Lane Swamp to the north and east and Swift Creek to the south. Groundwater flow in the area of the site is generally from west to east with a northeast component of flow toward Lane Swamp at the north end of the site, and a southeast component of flow toward Swift Creek at the south end of the site. 2.2 Contaminant Fate and Transport The key features of the site conceptual model for contaminant fate and transport are summarized as follows: ■ The depth to groundwater ranges from 0 feet bgs at the creeks and swamps to more than 6 feet in topographically higher areas (not including the beneficial fill footprint). ■ The regional groundwater flow regime within the surficial (alluvial) aquifer flows west to east with north and south flow components near Swift Creek and Lane Swamp which serve as shallow groundwater discharge features. ■ The estimated groundwater velocities at the site are very low. The historical calculated groundwater velocities are approximately 6 to 27 feet per year for the surficial (alluvial) aquifer and approximately 0.03 feet per year for the deeper Yorktown aquifer. ■ Prior to the 2018 corrective action, seasonal rises of the underlying water table and rainfall infiltration downward through the old soil cap resulted in water infiltration into the coal ash fill. Constituents www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 3 WATER QUALITY MONITORING REPORT— MARCH 2O20 WATER QUALITY MONITORING ACTIVITIES Battleboro, Nash County within the coal ash fill were dissolved by the infiltration water and became mobile. The former infiltration mechanism has been mitigated by the corrective action. Once the infiltration water enters the surficial groundwater, it migrates laterally above a clay confining or perching layer within the alluvial aquifer zone towards the groundwater discharge features of Lane Swamp and Swift Creek which serve to limit the lateral extent of the affected groundwater. The limited lateral extent of the affected groundwater is evident at wells MW-2S and 2D, located approximately 200 feet east of the former perimeter of the beneficial fill, where no 2L groundwater exceedances are observed. Similarly, there is no evidence of affected groundwater to the west (upgradient) as evidenced by groundwater monitoring results at current monitoring wells MW-5RS and MW-5RD and former monitoring wells MW-5S and 5D. ■ Based on historical groundwater monitoring results, the groundwater quality impacts at the site are limited to the surficial aquifer zone. No groundwater quality impacts are detected in the deeper aquifer zone of the Yorktown Formation. The swamps and creeks surrounding the beneficial fill site act as a "natural perimeter drain" and intercept the affected groundwater. Based on the historical surface water monitoring results, there are no surface water quality impacts to Lane Swamp or Swift Creek due to affected groundwater from the site. 3. WATER QUALITY MONITORING ACTIVITIES 3.1 Objectives Demonstration of effectiveness of the completed remediation is the primary objective of the water quality monitoring program (i.e. remedial performance monitoring). This objective can be achieved primarily by monitoring the success in reducing the site -specific contaminants of concern (COC) in groundwater in the site monitor wells and thereby mitigating the potential for surface water quality impacts due to contaminated groundwater migration and discharge to surface water. The applicable preliminary remedial goals for groundwater and surface water are summarized below. www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 4 WATER QUALITY MONITORING REPORT— MARCH 2O20 WATER QUALITY MONITORING ACTIVITIES Battleboro, Nash County 1compounds • • NC 2L •. •NC Surface Water 2B Standard Arsenic • 0.01 • 0.15 Barium 0.7 NE Cadmium 0.002 h Chromium (Total) 0.01 h Lead 0.015 0.025 Mercury 0.001 0.000012 Selenium 0.02 0.005 Silver 0.02 0.00006 Sulfate 250 NE pH 6.5-8.5 6.0-9.0 North Carolina 2L Groundwater Quality Standard 2 North Carolina Surface Water Quality Standard for Class C Waters NE = Not Established mg/L = milligrams per liter h = hardness dependent dissolved metal standard Water quality monitoring is conducted in accordance with the Corrective Action Plan (ERM March 2015).

Well purge logs were completed for each monitor well to document the stabilization of field parameters prior to sample collection. Well purge logs are provided in Appendix B. The groundwater and surface water samples were placed in laboratory supplied containers and placed on ice. The samples were submitted to North Carolina certified laboratory Pace Analytical Services (Formerly Shealy Environmental Services) (NC329) and were analyzed for eight specific metals, sulfates and total dissolved solids using the analytical methods summarized below: Analytical Methods .. . • • 1 EPA Method 6010 Arsenic Barium Cadmium Chromium (Total) Lead Selenium Silver EPA Method 7470C Mercury EPA 300.0 Sulfates SM 2540 C Total Dissolved Solids 4. MONITORING RESULTS 4.1 Groundwater Monitoring Results Groundwater monitoring activities were conducted at 11 monitor wells at the Site. Groundwater depth -to - water gauging and elevation data are presented in Table 2. The groundwater elevations in the surficial aquifer on March 9, 2020 ranged from 90.55 ft MSLat MW-6 located on the east (downgradient) side of the Site to 94.80 ft MSL at MW-4 located on the west (upgradient) side of the Site. The groundwater elevations are below the base of the CCB fill which generally ranges from 94 to 99 ft MSL from east to west. A potentiometric surface map for the surficial (alluvial) aquifer zone for the March 2020 monitoring event is presented as Figure 3. Groundwater flow in the surficial aquifer over most of the Site is generally west to east towards Lane Swamp Swift Creek, which serve as groundwater discharge zones. Using the current groundwater elevation data, the hydraulic gradients for the Site were calculated and are summarized below. • • draulic Gradients 09-Mar-20 Well Head Head Distance Hydraulic Gradient Designation Elevation Change Change (ft) (ft) (ft) (ft/ft) • • • ® 11 11 1 11 •� :1 ® �11 11 1 11• - .•- Hvdraulic Gradient0.0047 www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 6 WATER QUALITY MONITORING REPORT — MARCH 2O20 Battleboro, Nash County MONITORING RESULTS Groundwater seepage velocities were calculated using Darcy's equation, summarized as: Where: V=(Kxi)/ne V = seepage velocity of groundwater in Wday K = hydraulic conductivity in ft/day i = hydraulic gradient (ft/ft) ne = effective porosity As summarized below, based on the March 2020 hydraulic gradients and the previously calculated mean hydraulic conductivities, the estimated groundwater seepage velocity in the surficial aquifer zone using a primary porosity range of 10 to 25% is approximately 4 to 9 feet per year.

Constituents that exceeded North Carolina 2L groundwater standards are summarized on Figure 4. Laboratory analytical reports for the sampling event are provided in Appendix D. A historical groundwater data summary is provided in Appendix A. For the March 2020 monitoring event, five analytes were detected above their respective North Carolina 2L Groundwater Standards, as summarized in the following table. www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 7 WATER QUALITY MONITORING REPORT — MARCH 2O20 Battleboro, Nash County MONITORING RESULTS Current Maximum Concentrations in Groundwater — March 2020 Arsenic 0.093 0.01 Cadmium 0.012 0.002 Lead 0.26 0.015 Sulfate 770 250 Total Dissolved Solids 10,000 500 mg/L = milligrams per liter Sulfate, a primary indicator analyte for CCB contaminant releases, was detected in groundwater at concentrations above its 2L standard (250 mg/L) at 5 of the 11 monitor wells. The distribution of sulfate concentrations across the Site is depicted in plan view in Figure 5. A hydrogeologic profile across the Site, including sulfate concentrations in groundwater, is presented in Figure 6. The highest concentrations of sulfate were detected in groundwater samples from monitor wells located on the east- northeast (downgradient) end of the site, with 740, 770 and 710 mg/L sulfate detected at MW-6, MW-7 and MW-8, respectively. At MW-3 located on the southern (locally downgradient) side of the Site, a substantial decrease in the sulfate concentration occurred: the March 2020 sulfate concentration of 580 ug/I at MW-3 represented a 42 percent decrease from the previous monitoring event of June 2019 (1,000 ug/1), and was the lowest sulfate concentration at MW-3 since December 2011 (410 ug/1).. Graphs of sulfate concentrations over time for selected monitor wells are presented in Figure 7. Since the completion of the corrective action in January 2018, decreasing to stable sulfate concentration trends are evident at MW-3, MW-6, MW-7 and MW-8. Notably low values of pH were measured in the groundwater samples from MW-6 (3.7), MW-7 (4.0) and MW-8 (3.9). The low pH values at the three wells are consistent with historical monitoring results, and correlate with detections of arsenic and lead, in addition to sulfate, at concentrations above their respective North Carolina 2L groundwater standards at the three wells. There were no exceedances of 2L standards in the three monitor wells located on the west (upgradient) side of the Site (MW-4, MW-5RS & MW-5RD). Other than MW-1 S, the other three monitor wells located on the east side of the Site (MW-1 D, MW-2S & MW2D) only had one exceedance (in MW-1 D) of the 2L standards for one parameter, total dissolved solids. The elevated TDS concentration at MW-1 D does not appear to be attributable to sulfate or metals which were not present at elevated levels. 4.2 Surface Water Monitoring Results Consistent with historical monitoring results, the March 2020 surface water monitoring results indicated no exceedances of any North Carolina 2B surface water standards for any samples collected from Swift Creek (SW-1) and Lane Swamp (SW-2 & SW-3). The March 2020 surface water sampling results are summarized in Table 3. Laboratory analytical reports for the surface water samples are provided in Appendix D. Historical surface water data is summarized in Appendix A. 4.3 Laboratory Data Quality Analysis Quality assurance/quality control (QA/QC) samples collected during the March 2020 groundwater sampling activities included one blind duplicate sample collected at MW-1 S. The duplicate sample of MW- 1 S and the MW-1 S sample results can be compared in Table 3. The analytical results of the MW-1 S and duplicate groundwater samples compare favorably indicating no analytical discrepancy. www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 8 WATER QUALITY MONITORING REPORT — MARCH 2O20 Battleboro, Nash County SUMMARY 5. SUMMARY Corrective actions have been implemented at the Site to address groundwater quality impacts in accordance with the approved CAP. The corrective actions were completed in January 2018 and included temporary removal of CCB materials to allow raising the floor foundation above the seasonal high groundwater table, placing the CCB materials on the raised floor in a reduced footprint, installation of a synthetic liner (cap) over the limits of the CCBs, and drainage improvements to minimize rainfall infiltration. Groundwater and surface water monitoring activities are being conducted at the Site to monitor the effectiveness of the corrective actions. The March 2020 water quality monitoring event evaluated groundwater and surface water quality conditions at the Site approximately 2.2 years after the corrective action completion. Since the completion of the corrective action in 2018, for the 5 monitor wells with the historically most elevated sulfate levels, decreasing or stable trends in sulfate concentrations in groundwater are evident in 4 of the 5 monitor wells. The trend of decreasing sulfate concentrations indicates that the corrective action is effectively mitigating the groundwater quality impacts at the Site. The March 2020 surface water quality results continue to demonstrate that there have been no surface water impacts to Swift Creek or Lane Swamp due to discharges of affected groundwater from the Site. In accordance with the CAP, semi-annual water quality monitoring will continue at the Site. www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 9 WATER QUALITY MONITORING REPORT — MARCH 2O20 Battleboro, Nash County SUMMARY Figures Figure 1 Site Location Map Figure 2 Site Map and Monitor Well Locations Figure 3 Shallow Groundwater Potentiometric Map — March 2020 Figure 4 Groundwater Analyses - Constituents Exceeding 2L Groundwater Standards — March 2020 Figure 5 Groundwater Analyses —Sulfate —Surf icial Aquifer Figure 6 Hydrogeologic Profile A -A' Figure 7 Sulfate Concentrations over Time —Selected Monitor Wells www.erm.com Version: 1.0 Project No.: 0397281 Client: ReUse Technology November 2, 2020 Page 10 ,I a� SITE LOCATION -� I � all. a1£vCUTCHIN i= L- -� o I aar I� c,\ O'U1�TT - ROCKY M 9 ^ .,-�_ ` aam aanle�wro 1l W,amcsTaa �✓�� \ m � Y� - - o + — SOURCE: USGS 7.5 MINUTE TOPOGRAPHIC QUADRANGLE: L SCALE 1:24000 1 1/2 0 1 MILE u NORTH CAROLINA 1000 0 1000 2000 3000 4000 5000 6000 7000 FEET N D 7 b CONTOUR INTERVAL 10 FEET DOTTED LINES REPRESENT 5-FOOT CONTOURS QUADRANGLE LOCATION NATIONAL GEODETIC VERTICAL DATUM OF 1929 SWIFT CREEK FIGURE i z ERM, NC INC.

Mercury The matrix spike/matrix spike duplicate (MS/MSD) associated with sample -011 had mercury recovered outside of the acceptance limits. The laboratory control sample (LCS) was recovered within the required acceptance limits; therefore, this likely demonstrates a matrix effect. Inorganic Non -Metals Sulfate batch 48397 did not include a MS/MSD due to instrument error.
