Reynolds Tobacco Company. The closed landfill is located northeast of the jurisdictional boundaries of Rural Hall, Forsyth County, North Carolina and the location of the Site along with topographic map coverage of the vicinity are shown on Figure 1. Historical monitoring data indicate the occurrence of certain inorganic compounds in excess of the North Carolina Groundwater Standards (15A NCAC 2L) and Surface Water Standards (15A NCAC 213) in portions of the landfill site. A Corrective Action Plan (ERM) to restore groundwater quality beyond the compliance boundary, to stop unacceptable impacts to the adjacent surface waters, and to reduce the overall groundwater contamination at the facility was approved by the North Carolina Department of Environmental Quality (NCDEQ, formerly known as Department of Environment and Natural Resources) on February 19, 2014. The selected remedy includes source area contaminant control via the previous installation of the synthetic liner (cap) over the limits of waste plus drainage improvements (completed in 2012) to minimize rainfall infiltration, leachate generation and discharge of constituents to groundwater, to allow intrinsic remediation of the existing affected -groundwater. The September 2018 groundwater and surface water sampling event represents the thirteenth semi- annual monitoring event conducted at the site since the completion of the synthetic cap installation and the drainage improvements. 2. HISTORICAL GROUNDWATER AND SURFACE WATER QUALITY Groundwater and surface water quality monitoring has been conducted in the vicinity of the Edwards Road Landfill since 1989 in accordance with the conditions of Permit Number 34-05 and subsequent to the closure of the landfill, in accordance with the approved Post Closure Monitoring Plan. An updated water quality monitoring plan presented in the February 2014 CAP (ERM) was approved by NCDEQ on February 19, 2014 and is summarized in Section 3. Figure 2 depicts the locations of the groundwater monitor wells and surface water sampling locations and Table 1 presents a summary of available well construction details. Historical laboratory analytical results for available groundwater and surface water samples are summarized in Appendix A. 3. SUMMARY OF MONITORING PROGRAM Routine groundwater and surface water monitoring activities were conducted on September 11 - 13, 2018 and are summarized in the following table: www.erm.com Version: 1.0 Project No.: 0441331 Client: R.J.

Figure 6 depicts the isoconcentration contours of sulfates in groundwater at the site and Figure 7 presents a hydrogeologic conceptual site model and cross-section. Sulfate concentrations in groundwater and surface water over time are presented graphically on Figures 8 and 9, respectively. 4. DESCRIPTION OF WATER QUALITY CONDITIONS The following sections highlight key findings from the analytical results. 4.1 Site Hydrogeology The Site geology consists of fractured bedrock (gneiss and schist) overlain by partially weathered rock and a mantle of residual soils near the surface. The depth to bedrock beneath the Site generally ranges from 10 to 50 feet bgs. The first occurrence of groundwater beneath the upper portion of the site is within the fractured bedrock. In the lower portions of the site near the streams, groundwater is encountered within the partially weathered rock above the top of hard bedrock (transition zone). Shallow groundwater beneath the Site migrates either along the top of bedrock or along the permeable zones within the shallow fractured bedrock zone and discharges into nearby creeks, namely Leak Creek and its tributaries. The regional groundwater flow regime within the lower portion of the deep bedrock aquifer is north-eastward toward the nearest regional drainage feature, Town Fork Creek. The depth to groundwater in the top -of -rock aquifer zone ranges from approximately 0 feet at the creeks to 13 feet in shallow monitor wells. The depth to water in the bedrock aquifer ranges from artesian conditions to approximately 110 feet below ground surface in the measured wells. Using September 2018 depth to water measurements, Site groundwater elevations and hydraulic gradients for the Site were calculated as summarized below. Horizontal Hydraulic Gradient - Saprolite/PWR September 12, 2018 Well Reference Depth to Head Head Distance Hydraulic Designation Elevation Water Elevation Change Change Gradient ft MSL ft ft ft ft ft/ft W-1 822.68 15.88 806.80 26.80 180 0.1489 Leak Creek a 780.0 0.00 780.0 W-3 804.43 4.24 800.19 14.68 80 0.1835 Leak Creek a 785.5 0.00 785.5 Average Hydraulic Gradient 0.1662 2 Leak Creek bed elevation represents groundwater discharge line Based on the September 2018 hydraulic gradients, the groundwater flow rate (seepage velocity) in the saprolite/PWR aquifer zone was calculated as summarized below. www.erm.com Version: 1.0 Project No.: 0441331 Client: R.J. Reynolds Tobacco Co. December 2018 Page 3 2018-09 Edwards Rd LF Rural Hall GW Report R2.docx GROUNDWATER AND SURFACE WATER MONITORING DESCRIPTION OF WATER QUALITY CONDITIONS SEMI-ANNUAL SUMMARY REPORT—SEPTEMBER 2018 Edwards Road Landfill — Permit # 34-05 Rural Hall, Forsyth County, North Carolina Groundwater Seepage Velocity Calculation = Ki/ne where: K = hydraulic conductivity 0.080 ft/day (estimated) i = horizontal hydraulic gradient 0.1662 ft/ft (measured) ne = effective porosity 0.25 (estimated) Groundwater Seepage Velocity (Saprolite/PWR) = _ (0.08) ( 0.1662) / (0.25) = 5.32 x 10-2 ft/day or 19.4 ft/year The widely spaced locations of the bedrock monitor wells at the Site do not allow for calculation of the hydraulic gradient and groundwater flow rate of the bedrock aquifer. 4.2 Groundwater During the September 2018 groundwater sampling event, nine monitor wells, including PW-1, were sampled utilizing a low flow, low volume sample collection technique. During the event, three piezometers were sampled using a bailer due to insufficient volume for low flow sampling procedures. Piezometers PZ-1 and PZ-3 were dry during the sampling event. Presently, groundwater within the Site contains concentrations of sulfates, total dissolved solids, and five metals above the applicable North Carolina groundwater standards (NC 2L standard). Sulfate, the primary constituent related to the landfill, was detected in three groundwater samples in excess of the NC 2L standard. Iron and manganese were detected in eight of the 12 groundwater samples in excess of the NC 2L standard. Chromium (total) was detected in four of the 12 groundwater samples in excess of the NC 2L standard. Cadmium was detected in two of the 12 groundwater samples in excess of the NC 2L standard. Lead was detected in one of the 12 groundwater samples in excess of the NC 2L standard. The other metals, barium and selenium, were not detected in any of the groundwater samples in excess of their respective NC 2L standard. Aluminum, which does not have an established NC 2L standard, was detected in three of the 12 groundwater samples at concentrations in excess of background levels as indicated by background monitor well W-6. Dissolved solids were detected in three of the 12 groundwater samples in excess of the NC 2L standard. The elevated concentrations of iron and manganese in samples from the Site monitor wells may be attributable to their natural occurrence in groundwater as indicated by historical sample results from onsite background monitor wells (W-6 and former W-4). The elevated concentrations of metals in the piezometer samples are likely attributed to very high -observed turbidity and the inability to sample utilizing low flow procedures, due to insufficient water volume. As noted in Section 1, installation of the synthetic cap and construction of drainage improvements over the limits of waste were completed in September 2012. The September 2018 samples were collected approximately 6 years after the cap installation. Sulfate concentrations from the September 2018 samples from shallow monitor wells W-1 and W-2, located near the limits of waste, indicate a continuing overall trend of stable or decreasing sulfate levels since the installation of the synthetic landfill cap in 2012. The September 2018 sulfate concentrations from shallow monitor well W-3, also near the limits of waste, indicate a continuing trend of fluctuating sulfate levels since completion of the landfill cap installation in September 2012. During the same period, sulfate concentrations at bedrock monitor well W-313, located adjacent to W-3, continue to show an overall stable or decreasing trend. At W-1, a trend of fluctuating concentrations of iron is shown, while manganese and total dissolved solids concentrations remained stable compared to historical sample results prior to installation of the synthetic cap. At W-3, iron concentrations remained below the NC 2L standard and total dissolved solids concentrations remained stable. Manganese concentrations at W-3 were trending upward since installation of the www.erm.com Version: 1.0 Project No.: 0441331 Client: R.J. Reynolds Tobacco Co.

Overall, the September 2018 groundwater quality results and the historical concentration trends indicate that groundwater quality improvements are evident in most monitor wells located at the perimeter of the landfill. 4.3 Surface Water During the September 2018 sampling event, 10 surface water samples were collected. The September 2018 surface water monitoring results indicate there are no surface water quality impacts directly attributable to the landfill. Concentrations of sulfates in all of the samples collected during the September 2018 sampling event were below the applicable North Carolina surface water standards (NC 213 standards), although concentrations of total dissolved solids exceeded NC 2B standards in two of the 10 samples. Manganese was below the applicable North Carolina surface water standards (NC 213 standards) in nine out of the 10 samples. Iron concentrations exceeded NC 213 standards in three out of the 10 surface water samples, including the background and upstream samples (SS-20 and SS-25). Sulfate concentrations from the surface water samples with historical results display a generally declining to stable trend when compared to the September 2012 surface water results. Laboratory results from the surface water samples collected indicate concentrations of aluminum in exceedance of the applicable North Carolina surface water standard (NC 213 standard) at five of the 10 sample points, including the upstream (and background) samples at SS-20 and SS-25. Overall, September 2018 surface water quality results confirm that the corrective actions at the site have been effective for the remediation of the surface water quality at the site. Compared to upstream surface water quality, there have been four confirmed on -site exceedances of surface water quality standards in the streams since 2014. There have been no exceedances of surface water quality standards downstream of the landfill (SS-40, SS-80 or SS-90) since installation of the synthetic landfill cap in 2012. www.erm.com Version: 1.0 Project No.: 0441331 Client: R.J. Reynolds Tobacco Co. December 2018 Page 5 2018-09 Edwards Rd LF Rural Hall GW Report R2.docx GROUNDWATER AND SURFACE WATER MONITORING PRELIMINARY ANALYSIS SEMI-ANNUAL SUMMARY REPORT—SEPTEMBER 2018 Edwards Road Landfill — Permit # 34-05 Rural Hall, Forsyth County, North Carolina 5. PRELIMINARY ANALYSIS The September 2018 monitoring results demonstrate: Sulfate, total dissolved solids and five metals in groundwater samples exceed the NC 2L standards. Concentrations of all detected analytes in groundwater were within the normal range of historical fluctuations, with the exception of iron and manganese values detected in the three piezometers. The elevated concentrations of iron, manganese, chromium, and cadmium in the piezometers are not considered representative because the levels are attributed to very high observed turbidity and the inability to sample utilizing low flow procedures, due to insufficient volume. ■ Sulfate, manganese, iron, and total dissolved solids concentrations in groundwater samples exhibit different trends by constituent and location at the Site. Using sulfate as a primary indicator of landfill - related impacts, the sulfate concentration trends in groundwater, since completion of the landfill cap installation in September 2012, range from stable at W-1, to decreasing at W-2, to fluctuating at W-3. ■ No elevated concentrations of sulfates, metals or total dissolved solids have been detected in the off - site groundwater sample. The September 2018 groundwater sample collected from off -site monitoring well W-9, located to the southeast and side gradient of the landfill, contained a sulfate concentration (11,000 pg/L) which is well below the NC 2L standard (250,000 pg/L) and is lower than background levels observed in the upgradient monitoring well W-6. Concentrations of lead and sulfates in all 10 surface water samples did not exceed the applicable NC 2B standards. Concentrations of total dissolved solids in surface water samples exceeded the NC 2B standards at two of the 10 locations. Concentrations of manganese in surface water samples exceeded the NC 213 standards at one of the 10 locations (SS-60). Concentrations of iron detected in surface water samples exceeded the NC 2B standards at three of the 10 locations (two of which were background). Concentrations of aluminum detected in surface water samples exceeded the NC 213 standards at five of the 10 locations, including the two upstream, background locations. The presence of aluminum in the surface water samples is attributed to its natural occurrence in Piedmont soils and groundwater and is not related to the landfill. Concentrations of other detected analytes in surface water were within the normal range of historical fluctuations. Sulfate, manganese, and total dissolved solids concentrations in surface water samples from the Site have generally trended downward or remained stable compared to historical results. There have been no exceedances of surface water quality downstream of the landfill since the installation of the synthetic landfill cap in 2012. Installation of the synthetic cap and construction of drainage improvements over the limits of waste were completed in September 2012. The September 2018 samples were collected approximately 6 years after the cap installation and indicate that groundwater quality improvements are evident in most of the monitoring wells located at the landfill perimeter. The September 2018 surface water quality results indicate that there are intermittent exceedances (4 out of 11 sampling events) of the NC 2B standards at the SS-60 sample location. The water quality improvements at the site indicate that the cap installation and the drainage improvements at the landfill are effective remedial measures. www.erm.com Version: 1.0 Project No.: 0441331 Client: R.J.
