The Landfill is constructed and operated in phases per the Landfill's approved Facility Plan with Phase 4 being the next phase to be constructed. As specified in the rule, the scope and purpose of this DHR is to: • Provide adequate information to demonstrate compliance with the vertical separation and foundation standards set forth in the rule. • Provide an investigation of the hydrogeologic characteristics of the upper -most aquifer for the proposed phase of landfill development. The purpose of this investigation is to provide more detailed and localized data on the hydrogeologic regime for this area in order to design an effective water quality monitoring system. The following sections present descriptions of the physical, geologic and hydrogeologic settings for the proposed Phase 4 landfill and a history of previous investigations relevant to this DHR. The Solid Waste Section previously authorized utilizing data from previous investigations prepared for the CMS Landfill V to provide a characterization of the hydrogeology beneath Phase 4. A description of these previous investigations is in Section 1.4. 1.1 PHYSICAL SETTING The Charlotte Motor Speedway Landfill V is an active municipal solid waste management facility operating under the State solid waste permit 1304-MSWLF-1992. BFI Waste Systems of North America, Inc. a wholly owned subsidiary of Republic Services, Inc. owns and operates the Landfill. The Landfill's physical address is 5105 Morehead Road in Concord, North Carolina and is located on a combined 697.7-acre property. Figure 1 illustrates the location of the Landfill property on a United States Geological Survey 7.5-minute topographic quadrangle map. The Landfill is segmented into phases, with Phase 1 - 3 already constructed and operational or permitted to construct and Phase 4 is the next phase to construct. The proposed Phase 4 is roughly 7.78 acres in size. An existing groundwater and methane gas monitoring well network encompass all Phases of the Landfill as shown on Figures 2 and 3. 1.2 GEOLOGIC SETTING This section presents a summary of the regional and local geology for the CMS Landfill V. The Landfill is located within the Charlotte Belt of Piedmont physiographic and geologic province. The Charlotte Belt is characterized by intrusive felsic and mafic bodies with varying degrees of metamorphism. The Landfill is more specifically located within the Concord Pluton of the Charlotte Belt and is comprised of diorite (Ordovician to Devonian) with a mineral composition of cumulus olivine, clinopyroxene, and plagioclase and syenite (Silurian) with a mineral composition of orthoclase feldspar, augite, hornblende, biotite, and a coarse porphyritic texture with megacrysts of pink feldspar. Saprolitic overburden (aka saprolite) is the dominant upper -most geologic unit present at the Landfill. At most locations throughout the Landfill property, the saprolite transitionally grades from sediment material in which the relict metamorphic and igneous structures can be identified to the parent bedrock from which it is derived. The transition zone where finer sediment materials grade CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 5 into more pebble and cobble sized fragments has been designated the partially weathered rock (PWR) unit. Saprolite is present at most locations across the Landfill property. The residuum associated with the saprolite generally consists of clay and silt underlain by micaceous sandy silts and silty sands. In addition, alluvium and colluvium were observed as the upper -most geologic unit near smaller surface drainage features and the Rocky River. The alluvium is of limited thickness and overlays saprolite or bedrock. The alluvium ranges in grain size from clayey silt to poorly sorted sands. The saprolite consists primarily of red -brown or light to dark brown, fine micaceous sandy silt with clay with some areas of silty clay or silty sand. The saprolite generally grades to silty sand with rock fragments with depth. White, gray, brown, and black colors are present and correlate with the diorite, syenite, or diabase bedrock from which the soils were derived. Thin zones of red -brown, orange, or tan lean clays are also present in zones of differential weathering. Hard rock fragments and partially weathered rock (PWR) are present in this lower portion of the saprolite, which become larger and more frequent with depth. The contact with the underlying PWR or bedrock is gradational. The depth at which drilling refusal with hollow -stem augers was encountered defines the base of the saprolitic overburden. Deeply weathered bedrock material consisting of white, gray, dark grey, brown, or yellow silty sand with some intervals of sandy silt characterize the PWR. In addition, hard, but weathered, rock fragments are also present within the PWR. Local areas grey/black and green/gray materials derived from predominately-mafic parent rocks were also observed in the PWR unit. Diorite with diabase intrusions dominate the bedrock type underlying the Landfill. The contact with the syenite ring dike that encompasses the diorite unit is located just beyond the western boundary of the Landfill. Syenite was reported in isolated surface exposures near the northwest portion of the Landfill near banks of the Rocky River and in a few nearby cores within this relatively small area of the site. These occurrences are expected, as the contact between these bodies is gradational and typically not uniform on a local scale. Two small, northwest trending diabase dikes occur in this same portion of the site and previous investigations in portions of Phase 3 identified small east -west trending diabase dikes. The occurrence of the intrusions suggest a relationship between these intrusive rock units, the local joint patterns, and the flow path of the Rocky River and tributaries. The diorite is generally light gray and black in color, and generally comprises 90 percent of the rock mass. The remaining rock mass is comprised of the isolated syenite identified and, to a lesser extent, diabase intrusions. The syenite will appear similar to granite with black, gray, and brown fine to coarse -grained crystals in a white matrix and the diabase will generally be dark green/gray in appearance with fine to medium -grained crystals of similar color. Bedrock outcrops at the Landfill near the banks of Rocky River and tributaries were reported in previous investigations. No other bedrock outcrops at the Landfill have been observed. A fracture trace analysis was performed and reported in the Phase 2 (Cells F-H) DHR and Site Suitability Update. A map of the reported fracture trace analysis is provided in Appendix A. The dominant fracturing directions at the Landfill are from N25E to N35E / S25W to S35W. Secondary sets of fracturing are from N75E to N70E / N75W to N70W. Fracture directions appear uniform and correlate to the flow path of the Rocky River and tributaries. No seismic activity were identified in this or any of the previous investigations. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 6 1.3 HYDROGEOLOGIC SETTING This section presents a summary of the regional and local hydrogeology for Phase 4 and the overall Landfill. Groundwater in the Piedmont physiographic and geologic province occurs as unconfined aquifers in the saprolite, PWR, and fractured bedrock. These zones are interconnected through open fractures and pore spaces. The surface of the upper -most aquifer typically correlates to the local topography. The infiltration of precipitation recharges the upper -most aquifer. The recharge rate is primarily affected by rainfall intensity and duration, pre-existing soil moisture conditions, temperature (evaporation), and plant uptake (transpiration). Most of the property is comprised of the active landfill and support infrastructure and flood plain areas associated with Rocky River. Seasonal high-water tables are typically observed during the spring to early summer months of the year when maximum infiltration efficiency occurs due to lower temperatures and less plant uptake (less evapotranspiration). In addition, as snow and ice melt from the higher elevation during the spring months, the receiving rivers and streams will exhibit additional surge from the increased runoff volume and will influence groundwater elevations in nearby areas. Seasonal low-water tables are typically observed during the fall months when minimum infiltration efficiency occurs due to higher temperatures and greater plant uptake of water (more evapotranspiration). Precipitation that infiltrates into the ground will seep downward following the path of least resistance through zones of relatively higher conductivity in the saprolite and PWR. Upon contact with a less permeable surface (i.e. competent bedrock or clay confining layer), the water will spread laterally until it finds another relatively higher conductive pathway downward such as a weathered zone or a fracture, or until it is discharged to the surface water system. These discharges are generally intermittent, and generally occur in the secondary drainage features following precipitation events. 1.4 INVESTIGATION HISTORY The following subsections summarize the previous investigations as documented and presented in the Landfill's Initial Phase 1 Site Investigation, Phase 2 Cells 2A-2E DHR, Phase 2 Cells 2F-2H DHR, and Phase 3 DHR (Cells 21, 2J, 2K & 2M). Data and information in these previous documents is presented in this report only to the extent necessary to support the Phase 4 expansion. 1.4.1 Initial Phase 1 Site Investigation On November 30, 1987, the City of Concord approved the re -zoning of the un-developed property to allow construction of a sanitary landfill. Westinghouse Environmental and Geotechnical Services, Inc. (Westinghouse) initially investigated the property on behalf of Browning -Ferris Industries (BFI at the time) in 1988 as part of the site suitability study in support of the Site Plan Application. The investigation consisted of installation of test borings and observation and monitoring wells with rock coring performed at select locations to assess the suitability of the property for permitting and construction of a sanitary landfill. The North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR) Solid Waste Section (SWS) issued a Permit to Construct (PTC), Permit No. 13-04, for the Landfill on April 1, 1991, followed by minor permit amendments during the same year. The SWS approved the Permit to Operate (PTO) for Phase 1 Cell 1A and amendments to the PTC on March 6, 1992. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 7 1.4.2 Phase 2 Cells A-E DHR S&ME submitted a DHR for Phase 2 Cells 2A, 213, 2C, 2D, and 2E in February 1994 and subsequent revisions through 1995. 91 auger borings, 50 groundwater observation wells, and eight rock cores completed for the DHR investigation. Standard Penetration Tests (SPTs) were performed at select locations and at designated intervals during installation of the observation wells with collection of bulk and undisturbed samples for geotechnical testing and analyses. Installed observation wells slug testing for in -situ permeability was completed for calculating hydraulic conductivity. Changes to the Water Quality Monitoring Plan included conversion of select observation wells to permanent monitoring wells and the addition of two monitoring wells installed during cell construction. On April 25, 1995, a PTO amendment was completed and a PTC was issued for Phase 2 Cells 2A-2E. 1.4.3 Phase 2 Cells F-H DHR ENSR Consulting and Engineering (NC), Inc. submitted a DHR for Phase 2 Cells 2F, 2G, and 2H in 2003 with subsequent revisions through 2005. 129 test borings at 119 locations were performed as part of the DHR investigation. 99 of the borings were converted to groundwater observation wells, nine of which were deep wells screened in bedrock. Rock coring was performed at 16 boring locations. Standard Penetration Tests (SPTs) were performed at 54 boring locations at designated intervals during installation of the observation wells with collection of bulk and undisturbed samples for geotechnical testing and analyses. For 42 of the installed observation wells, slug testing for in - situ permeability was completed for calculating hydraulic conductivity. Changes to the Water Quality Monitoring Plan included conversion of five installed groundwater observation wells to permanent monitoring wells with the addition of four monitoring wells installed during cell construction. In addition, a receptor survey was updated and did not identify any existing or potential receptors in the area. On July 14, 2006, an amendment was made to the PTC for construction of Phase 2 Cells 2F-2H. 1.4.4 Phase 3 Cells I, J, K, and M DHR David Garrett and Associates submitted a DHR for Phase 3 Cells 21, 2J, 2K, and 2M in 2008 and a subsequent revision in 2009. 85 test borings were completed at 78 different locations with numerous test pits completed as part of the DHR investigation. Most of the borings were converted to groundwater observation wells with eight shallow and deep nested pairs. Rock coring was performed at 13 of the boring locations. Standard Penetration Tests (SPTs) were performed at select locations at designated intervals during installation of the observation wells with collection of bulk and undisturbed samples for geotechnical testing and analyses. For 26 of the installed observation wells, slug testing for in -situ permeability was completed for calculating hydraulic conductivity. Changes to the Water Quality Monitoring Plan included relocation of two monitoring wells and the addition of nine monitoring wells installed during cell construction. On April 12, 2010, an amendment was made to the PTC for construction of the Phase 3 landfill expansion. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 8 2.0 PHASE 4 LANDFILL INVESTIGATION ACTIVITIES The proposed Phase 4 landfill expansion area is located adjacent to the existing Phase 2 Cells 2C, 2D, 2E, and 2F, to the south and west of the referenced cells. The area for the proposed Phase 4 is roughly 7.78 acres in size and the investigative area is 19.59 acres. As described in the following subsections, this investigation includes previous site investigations borehole drilling, groundwater observation wells (aka piezometer) installation and surveying, groundwater level measurements, and aquifer testing. 2.1 BOREHOLE DRILLING To characterize the subsurface beneath and around the proposed Phase 4 landfill expansion area, boring logs from the previously completed investigations were used. At a minimum, the area of investigation was the area within the proposed waste unit footprint and waste unit compliance boundary. Borehole drillings were performed by North Carolina licensed drillers. Methods for advancing boreholes to target depths included hollow stem auger (HSA) and air rotary. A description of each drilling method utilized in the previous investigations are provided below. HSA drilling was conducted at designated locations to obtain lithologic information. Each HSA boring was advanced to the top of the bedrock (aka point of auger refusal) using various drill rigs and various outer diameter HSAs. Lithologic information was obtained through split spoon sampling at 2-foot intervals as outlined in ASTM Method D-1586 or logged from drill cuttings. During the driving of the split spoon sampler, blow counts were recorded and the sample was examined by the field technician and described for color, grain size, Unified Soil Classification System (USCS) code, and texture. The depth of the partially weather rock (PWR) stratum was noted where observed. The depth to top of bedrock was defined as the depth to auger refusal. Geotechnical samples collected during HSA drilling included grab, bulk, and undisturbed Shelby tubes samples. Geotechnical samples were collected and analyzed as described in Section 2.3. • Air rotary drilling was utilized to advance boreholes in bedrock to provide adequate annular space for well installation. The air rotary boreholes were drilled for the purposes of permanent groundwater monitoring well and piezometer installations in bedrock. Drill cuttings were logged continuously to identify rock type. Grain size of the cuttings was observed to characterize properties and quality of the rock being drilled. Various geologic, construction, and boring log recorded data for installed groundwater observation wells (aka piezometers) and groundwater monitoring wells previously and currently located within the Phase 2 and Phase 3 investigation areas provided in Appendix B. The following selected lithologic observations are extrapolated from the data: • The overburden observed during drilling included alluvium and saprolite. Across the Phase 2 and 3 landfill areas, saprolite is observed to range in thickness from 2 feet to greater than 20 feet. Saprolite observed to be thicker beneath hills and ridges compared to side slopes or drainage areas. The saprolitic soils have been observed to be dry to saturated where encountered. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 9 • PWR thickness across the Landfill property ranges from absent where alluvium or saprolite directly overlies bedrock to more than 20 feet. Within the proposed expansion area for the Phase 4 landfill, the average PWR thickness estimated at 0 to 5 feet. • PWR is observed to be dry to saturated at most boring locations. Saturated conditions observed in the PWR at two locations within the Phase 4 area. Bedrock is anticipated to be largely diorite within the Phase 4 area. Bedrock fracture zones observed in the historical boring logs. Fracture zones can be identified by the sudden drop of the drill rod or drastic change in drilling conditions, often paired with a simultaneous pause in the chatter from the air rotary bit. When a substantial fracture was encountered that produced water or a drastic increase in water production, this was interpreted to indicate the presence a water -bearing fracture. This depth was targeted for well screen placement in bedrock. Stratigraphic cross -sections were created identifying the hydrogeologic and lithologic units and stabilized water table. These cross -sections are based on the historical lithological information and static groundwater elevations from the Phase 2 DHR investigation borings and routine monitoring of the groundwater wells at the Landfill. The cross -sections included as Figures 4 - 8 and a cross- section transect map provided as Figure 9. 2.2 ROCK CORING Rock coring was performed during previous DHR investigations utilizing a wire line double -tube core barrel retrieval methodology. A double tube core barrel was attached to the bottom of the drill rods and lowered to the bottom of the borehole and top of formation. The desired coring interval was drilled using a toothed core bit and potable water circulated inside the boring from the bottom of the core barrel to ground surface to displace drill cuttings. When the desired depth was reached or drilling conditions dictated as such, the core barrel and drill rods were retrieved from the borehole. The core sample was then extruded and placed into a box labeled with the core ID and depth intervals. The percent recovery, rock quality designation (RQD), orientation and frequency of likely fractures, joints angles, observed fracture infilling or coatings, gross mineralogy, and other notable characteristics were recorded during rock coring activities. The RQD was determined by dividing the total length of rock fragment longer than four inches over the total length cored. Core recoveries, RQD values, and lithologic descriptions for rock coring performed during previous investigations at the Landfill are provided in Table 1. Observations from the rock cores collected during previous investigations generally show a moderate to highly fractured top of bedrock that becomes more competent with depth. Recovery values range from zero to 100 percent and RQD values ranged from zero to 100 percent. These percentages indicate that the bedrock is differentially weathered and variably fractured. Recovery and RQD values generally increase with depth indicating less fracture density at greater depths. 2.3 GEOTECHNICAL ANALYSIS Bulk and undisturbed soil samples were collected and laboratory tested during previous DHR investigations using the following methods: CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 10 • Standard Proctor (ASTM D 698); • Particle size analysis (ASTM D 422); • Soil classification: Unified Soil Classification System (USCS) (ASTM D 2487); • Atterberg limits (ASTM D 4318); • Natural moisture content (ASTM D 2216); and • Undisturbed and remolded hydraulic conductivity (ASTM D 5084). Tabulated geotechnical field and laboratory data from previous Phase 2 and 3 DHR investigations provided in Appendix C and D and discussed further below. • Particle size distribution mostly silts and sands with less clay and gravels present with USCS classifications ML, CL, CH, SM, and SC. • Total porosity values in undisturbed samples ranged from 0.41-0.55 for the Phase 2 Cells 2A-2E and 0.39-0.61 for Phase 2 Cells 2F-2H. The porosity values for Phase 3 were established in DHR from soil sample particle size distributions and published procedures. These values ranged from 0.03-0.38. • Undisturbed saturated hydraulic conductivity values ranged from 1.10x10-4 cm/sec to 8.08x10-8 cm/sec. (Appendix D) 2.4 AQUIFER TESTING In -situ aquifer testing was performed during previous DHR investigations. A summary of the aquifer testing results is discussed in section 3.4.2. 2.5 GROUNDWATER LEVEL MEASUREMENTS Groundwater monitoring wells are present within and adjacent to the Phase 4 landfill expansion area. From the wells, the static groundwater level (aka depth to water) is measured and recorded during the course of routine monitoring for the Landfill. Depth to water measurements are recorded prior to well sampling for each monitoring event. Historical static water level measurements collected during routine semi-annual groundwater monitoring events that are pertinent to the Phase 4 investigation are provided in Table 2. In addition, historic groundwater elevations from previous investigations are included in Appendix E for piezometers and groundwater monitoring wells located within or near the Phase 4 expansion area. A summary of our findings from the groundwater level measurements is as follows: • The groundwater table elevations within the monitoring wells installed within the Phase 4 investigation area are generally higher than the top of bedrock elevations. • The groundwater table elevations within the piezometers have generally been higher than the top of bedrock elevation with the exception of OW-29, OW-28, and A-71. • The saprolite and fractured bedrock are the primary water -bearing units beneath the Landfill. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 1 1 3.0 HYDROGEOLOGIC EVALUATION To further characterize the hydrogeology beneath the Phase 4 landfill expansion area, the following data evaluation was performed: evaluation of groundwater elevations; assessment of groundwater flow direction; calculation of groundwater flow rate; vertical gradient assessment; and identification of top of bedrock surface. Data from previous DHR investigations were used for these data evaluations. 3.1 GROUNDWATER FLOW DIRECTION ASSESSMENT Groundwater flow at the Landfill property is generally from the east to the west, toward Rocky River, as shown on the April 2020 Groundwater Statistical Analysis Report (Jett 2020) groundwater contour map that is included as Figure 10. Most borings from previous investigations have been abandoned; therefore, for locations in which a groundwater elevation could not be measured during the course of routine monitoring, the historically reported groundwater elevations (Appendix E) were used for purposes of constructing groundwater flow contour lines. Groundwater contours were generated using AutoCAD surface mapping system software and altered utilizing professional judgement. The generated groundwater surface contours for the Phase 4 landfill expansion are shown on Figure 11. Observations regarding the direction of groundwater flow within the proposed Phase 4 landfill expansion area is as follows: • Groundwater contours mimic topographic contours. • Groundwater flows from north to south toward Rocky River. • A drainage control feature was originally located within the proposed Phase 4 expansion area. The groundwater flow direction within the Phase 4 landfill expansion area is shown on Figure 11. 3.2 GROUNDWATER ELEVATION EVALUATION Groundwater elevation data from the groundwater monitoring wells, piezometers, and borings installed throughout the Landfill for previous DHR investigations were compiled and provided in Appendix E. Based on this historical data, the maximum -recorded groundwater elevation was identified as the seasonally high groundwater elevation for each location. The seasonally high groundwater elevations, as well as source and dates for the data are presented in Table 3. From this data, a seasonal high groundwater contour map was created, included as Figure 11. The contours were generated using AutoCAD surface mapping system software and altered utilizing professional judgement. Observations regarding the seasonally high water table within the proposed Phase 4 landfill expansion area is as follows: • High groundwater levels typically occurred during the spring semi-annual monitoring events. • The upper -most aquifer is first encountered within the saprolitic overburden with the exception of OW-28, OW-29, A-7, and A-86. • The saturated zone is also found in the PWR and fractured upper bedrock. CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 12 • MW- 24 and MW-17 are located near an existing drainage feature where groundwater is expected to be above the top of bedrock. • The seasonally high water table mimics the surface topography. 3.3 VERTICAL GRADIENT ASSESSMENT The vertical hydraulic gradients for the monitoring well clusters were calculated to assess whether the area is a zone of groundwater discharge or recharge. The vertical hydraulic gradient is the change in head (groundwater elevation) per unit of vertical distance (elevation of the middle of the well screen) between wells. The vertical hydraulic gradient was calculated using the difference between groundwater elevations measured in well pairs during previous investigations. Vertical gradient calculations are shown in Appendix F. The calculated historical vertical hydraulic gradient that will most closely correlate to Phase 4 is the P-11 to P-31 comparison from the Phase 3 DHR, is upward, and has a reported range of -0.062 to - 0.051 feet per foot. A positive vertical gradient indicates a vertically downward hydraulic gradient (recharge zone) and a negative gradient indicates a vertically upward hydraulic gradient (discharge zone). This indicates that within the Phase 4 limits a discharge zone is present. Water level data from previously installed nested monitoring well pairs indicate that upward gradients exist near and within drainage features. Downward vertical gradients have been observed during previous investigations in nested wells outside of the influence of the Landfill's drainage features. 3.4 GROUNDWATER FLOW RATE CALCULATIONS An aquifer's flow rate is influenced by the hydraulic gradients, hydraulic conductivity, and porosity of the aquifer. Details regarding each component of the flow rate calculation and groundwater flow rate calculations for the upper -most aquifer are presented in the following sub -sections. 3.4.1 Horizontal Hydraulic Gradient The horizontal hydraulic gradient (i) is the change in head (dH) per unit of distance (dQ in the direction of groundwater flow. Hydraulic gradient is the one factor for groundwater velocity calculations that may change over time. Horizontal hydraulic gradients were calculated using the difference between groundwater contour lines within the Landfill property as shown on the April 2020 Groundwater Contour Map (Figure 10). The hydraulic gradients used for groundwater flow rate calculations were 0.022 feet per foot and 0.019 feet per foot depending on location. The semi- annual groundwater monitoring calculated groundwater flow velocity for the Landfill from April 2012 to October 2020 provided in Appendix G. 3.4.2 Hydraulic Conductivity Hydraulic conductivity (K) is the measure of a specific geological unit's ability to transmit water and is necessary to calculate groundwater rate. It is expressed as the volume of water that will move in a unit of time at a hydraulic gradient through a unit area measured at right angles to the direction of flow. The hydraulic conductivity of the upper -most aquifer for Phase 4 is derived from previous investigations. A summary of the historical aquifer test results is shown in Appendix H. Hydraulic CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 13 conductivities for piezometers and groundwater monitoring wells in and around the proposed Phase 4 were reviewed and included in the site -wide groundwater flow rate calculations. In summary, hydraulic conductivity (Ks) values for piezometers within the soil/saprolite aquifer (in Phase 3) vary from 4.71 x 10-6 cm/sec (P-14) to 1.08 x 10-6 cm/sec (P-73), within the PWR aquifer from 5.53 x 10-6 cm/sec (P-16) to 9.16 x 10-7 cm/sec (P-60), and within the bedrock aquifer from 4.99 x 10-5 cm/sec (P-52) to 2.78 x 10-6 cm/sec (P-13). 3.4.3 Porosity Porosity is the measure of a material's pore space through which water can flow. The upper -most aquifer at the Landfill is found within the saprolite/bedrock interface or within the fractured bedrock. Based on porosity values utilized for previous DHR investigations, effective and total porosity values range widely as shown in Appendices D and H. 3.4.4 Groundwater Flow Rate The groundwater flow rate for Phase 4 was calculated using the Darcy equation shown below. rM Vx = ne where: vx = groundwater flow rate K = hydraulic conductivity i = horizontal hydraulic gradient n = total porosity of the aquifer As shown in Appendix G, groundwater flow rates were calculated utilizing the following data • An average horizontal hydraulic gradient of 0.021. • The saprolite (1.10x10-3 cm/sec), PWR (2.Ox10-4cm/sec), and bedrock (7x10-5 cm/sec) values for hydraulic conductivity. • A total porosity value of 0.16 for saprolite, 0.20 for PWR, and 0.07 for bedrock. The Landfill's April 2020 water quality monitoring event had groundwater flow rates ranging from 22 feet/year to 135 feet/year. Historical groundwater flow from routine monitoring events range from 21 feet/year to 146 feet/year. Groundwater flow rates from the Phase 2 Cells 2F-2H DHR range from 10.95 feet/year to 200.75 feet/year in upland areas, 7.3 feet/year to 120.45 feet/year in the mid surface elevations, and 124.1 feet/year to 182.5 feet/year in the lower surface elevations. Therefore, the April 2020 flow rate range is consistent with flow rates previously documented. 3.5 TOP OF BEDROCK EVALUATION A bedrock contour map was created for the Phase 4 landfill expansion area. The bedrock contour map was created by compiling the top of bedrock elevation data from groundwater monitoring wells, piezometers, and borings installed within and near the Phase 4 area from the various investigations previously completed for the Landfill. The top of bedrock elevations for locations within the Phase 4 CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 14 investigation area are shown in Table 4. The top of bedrock was interpreted as the point at which auger refusal was identified during drilling, or as reported in the table and boring logs provided in Appendix I. A top of bedrock surface contour map was generated using AutoCAD surface mapping system software and adjusted utilizing professional judgement and is included as Figure 12. Observations regarding the top of bedrock surface within the proposed Phase 4 landfill expansion area is as follows: • Depth from the ground surface to the top of the bedrock unit ranges from 14 feet at boring A-72 location up to 30 feet at monitoring well MW-24 location. The depth to bedrock is generally shallow in drainage features and deeper beneath topographic highs. • The bedrock surface within the Phase 4 area generally mimics the surface topography. 3.6 VERTICAL SEPARATION ASSESSMENT A municipal solid waste landfill (MSWLF) unit shall be constructed so that the post -settlement bottom elevation of the base liner system is a minimum of four feet above the seasonal high ground- water table and bedrock datum. To comply with this requirement, seasonally high groundwater and top of bedrock surface contour maps are created as presented in Sections 3.2 and 3.5, respectively. These maps will be provided to the landfill design engineer for the development of base grades for the proposed Phase 4 waste unit. 4.0 WATER QUALITY AND METHANE GAS MONITORING An updated groundwater and methane gas monitoring plan that included development of Phase 4 was submitted to NCDEQ on October 8, 2020 and were subsequently approved. These plans included the continual monitoring of MW-33 and MW-34 groundwater monitoring wells, abandonment of MW-24, and the relocation of wells MW-17 and MW-17A down gradient of the proposed Phase 4 expansion area. Relocated wells MW-17 and 17A will be installed following construction the the Phase 4 landfill expansion. Well abandonment and installation will be completed and the proper completion records and certifications submitted to NCDEQ as delineated in 15A NCAC 2C Rule. The Landfill's current and proposed monitoring network is shown on Figure 2 and 3. A certification by a Licensed Geologist that all borings at the site that have not been converted to permanent monitoring wells will be properly abandoned in accordance with the procedures for permanent abandonment of wells. 5.0 CONCLUSIONS The geologic and hydrogeologoc conditions for the proposed Phase 4 landfill expansion are consistent with previous DHR investigations completed for MSWLF units constructed at the Charlotte Motor Speedway (CMS) Landfill V. No unusual or unexpected geologic features were identified within the Phase 4 landfill expansion area. Groundwater and bedrock surfaces typically mimic the surface topography across the Landfill. Groundwater flow direction is from north to south across Phase 4 towards Rocky River. Groundwater gradients have exhibited both upward and downward vertical flows across the Landfill. As a result, to be relocated shallow and deep well pair, MW-17 and MW-17A, are identified as the down -gradient CMS LF V Phase 4 www.scsenaineers.com Design Hydrogeologic Report 15 compliance point for Phase 4, once constructed. This well relocation is discussed in the previous Section 4.0. Based on the findings presented in this DHR and previous DHR submittals, the Phase 4 area is considered suitable for expansion of the Charlotte Motor Speedway Landfill V. 6.0 REFERENCES American Society of Testing and Materials (ASTM).

The USDA system used 0.005 mm as the cutoff until 1935, but since changed to 0.002 mm. Some practitioners still use 0.005, but the USCS has adopted 0.002. The laboratory reported both USCS and USDA classifications, for which USCS classifications were reported in the original version of this table. The grain size distributions have been checked and reported values are consistent with USCS classification cutoff values. *Effective porosity values were determined from the grain size distribution referencing Fetter (1988), which involved using different cutoff values and a ternary diagram to determine specific yield, referenced in USGS Water -Supply Paper 1662-D (1967).

As previously mentioned, the observation wells consisted of generally 5 to 10-foot machine slotted screens. All of the auger borings that penetrated the groundwater not converted to observation wells had a temporary standpipe installed. Eight of the observations wells located outside the landfill (including 5 rock core nested locations) were installed as Type II monitoring wells for potential use as future groundwater monitoring wells. �l Groundwater levels were measured using an electronic water level indicator from the top of the PVC standpipe. The top of the PVC standpipe as well as ground surface elevations were surveyed by F.D. Lawrence & Associates, P.A. The groundwater level measurements and elevations are presented in Table 4. Groundwater levels in the area of Cells 2C through 2E will continue to be monitored on a monthly basis until these areas are ready for construction.

test The grain size defining the clay fraction used in this work is 0.002 mm (2 microns), as referenced by Atterberg (1905), Terzaghi and Peck (1948), Lambe and Whitman (1969), Holtz and Kovaks (1981). The USDA system used 0.005 mm as the cutoff until 1935, but since changed to 0.002 mm. Some practitioners still use 0.005, but the USCS has adopted 0.002. The laboratory reported both USCS and USDA classifications, for which USCS classifications were reported in the original version of this table. The grain size distributions have been checked and reported values are consistent with USCS classification cutoff values. *Effective porosity values were determined from the grain size distribution referencing Fetter (1988), which involved using different cutoff values and a ternary diagram to determine specific yield, referenced in USGS Water -Supply Paper 1662-D (1967).

This results in a very skewed graphic, that combined with the distance between monitored locations (due to the size of the site), resulting interpretations of the data or the generated flow lines may vary greatly, and may not represent an accurate groundwater flow regime. 3) The hydraulic conductivity of the hydrologic units (Table 2) generally decreased with depth. To show flow lines and equipotential lines on a cross-section where changes in hydraulic conductivity values occur, the equipotential lines (and flow lines) must be refracted using the tangent law. The geometric average hydraulic conductivity values decrease from the upper unit to the next lower unit by the following: Saprolite to PWR: 0.20 PWR to Upper Bedrock: 0.35 Upper to Lower Bedrock: 0.04 While each of these factors would not prohibit the construction of flow nets, the combined effect of these factors present a very complex and challenging task. In addition, the complexities of generating the flow nets may also yield an inaccurate representation of the actual groundwater flow regime. 4 Q O LL Q Z O (7 C N H J co mw H F� mQ W w a 9 LL LL O m Q N T.
