INTRODUCTION On behalf of the City of Charlotte, Geosyntec Consultants of NC, PC (Geosyntec) has prepared this Semi-Annual Monitoring Report, Second Half 2016 for the City of Charlotte’s Former York Road Landfill. This report presents the results through November 2016 of groundwater, surface water, and methane monitoring conducted at the former landfill since the previous Semi-Annual Monitoring Report (Geosyntec, 2016a) was submitted in May 2016. 1.1 Site Description and History The Former York Road Landfill (herein referred to as the “Site”) is an approximately 400-acre Site located along West Tyvola Road and South Tryon Street (Highway 49) in Charlotte, Mecklenburg County, North Carolina (Figure 1). The Site was operated as an unlined municipal solid waste landfill from 1968 to 1986, with the last expansion occurring in 1983 (under NCDEQ Facility Permit Number 60-03). The landfill waste placement area consisted of a total of approximately 168 acres, which was divided into six cells referred to as Landfill Areas A through F. The precise locations of waste placement boundaries are uncertain and have been estimated by others, as shown in Figure 2. The former landfill was developed with the construction of West Tyvola Road, a golf course, and a recreational park following closure in 1986. Today, the Site is utilized by the Renaissance Park Golf Course and Renaissance Park, which include recreational facilities for golf, softball, soccer, biking, and disc golf. In July 2016, some of the athletic fields at Renaissance Park (including the softball and soccer facilities) were closed to public use as a result of the effects of the former landfill on upkeep of the fields. Other facilities including the golf course, bike trails, and disc golf courses remain in operation. 1.2 Hydrogeologic Setting The Site is located within the Charlotte Belt of the Piedmont Physiographic Province. The topography of the Piedmont Province is generally characterized by gently rolling hills ranging in elevation from approximately 300 to 1200 feet (ft) above mean sea level (MSL), and the Site elevation ranges from approximately 580 to 680 ft above MSL. Geologically, the province is comprised primarily of crystalline metamorphic rocks (schists and gneiss, and to a lesser extent, phyllite and slate) of Precambrian to Paleozoic age. These units are often highly deformed with multiple fracture and Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 2 11.2016 foliation planes, which promote anisotropic groundwater flow. The occurrence and movement of groundwater at the Site is typical of the Piedmont formation, and generally occurs within two hydrogeologic units. A shallow hydrogeologic unit typically occurs within the soils and saprolite (weathered residuum which mantles bedrock). A deeper hydrogeologic unit is generally associated with secondary porosity (fractures or open spaces) within the crystalline bedrock. A transition zone of fractured bedrock occurs between saprolite and bedrock and is generally referred to as partially weathered rock (PWR). Groundwater flow in the shallow hydrogeologic unit is controlled by local topographic features, where recharge occurs in upland areas and discharge occurs in drainage features such as streams, rivers, or lakes. Recharge to the shallow hydrogeologic unit is primarily the result of infiltrating precipitation. Groundwater flow in the deeper water- bearing zone is controlled by the distribution and degree of interconnection of openings in the rock. 1.3 Regulatory Authority The York Road Landfill was closed under the 10 NCAC 10G, Section .0500 rules as referenced in the 21 August 1987 closure letter from the North Carolina Department of Human Resources, Division of Health Services. These regulations were transferred and recodified into title 15A NCAC 13B Section .0500, effective April 1990. Water quality monitoring at the Former York Road Landfill is conducted pursuant to the Water Quality Monitoring Plan (WQMP; Delta, 2004), which was developed in accordance with relevant and applicable North Carolina Department of Environmental Quality (NCDEQ, formerly North Carolina Department of Environment and Natural Resources [NCDENR]) Solid Waste Management Rules. Groundwater and surface water sampling is conducted semi-annually, typically in March and September. Landfill gas monitoring is conducted pursuant to the Landfill Gas Monitoring Plan (LGMP; HDR, 2011) for the Site. As stated in the LGMP, the 15A NCAC 13B Section .0500 rules and closure letter for the Site does not specify landfill gas monitoring requirements. Therefore, landfill gas monitoring is regularly conducted in general accordance with the LGMP, which was developed to provide reasonable protection to public health and the environment. Landfill gas monitoring is conducted on a quarterly basis (typically in January, April, July, and October). Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 3 11.2016 2. MONITORING ACTIVITIES AND FIELD METHODOLOGY The following sections describe field methodology for groundwater, surface water, and methane monitoring conducted during the current reporting period. 2.1 Groundwater Monitoring Groundwater monitoring was conducted pursuant to procedures in the WQMP. The current monitoring network includes twenty-three (23) monitoring wells, with eighteen (18) groundwater monitoring wells included in the sampling network pursuant to the WQMP. Monitoring wells are screened across one or more of the three hydrogeologic units at the Site (saprolite, PWR, and bedrock). Monitoring well construction details are listed in Table 1, and locations are depicted in Figure 2. A schedule for sample collection and associated laboratory analyses conducted for each well under the WQMP is listed in Table 2. Groundwater sampling, water level measurements, and laboratory analysis conducted during this reporting period were performed from 6 September through 28 September 2016 by Pace Analytical Services (Pace) of Charlotte, NC. Groundwater level measurements from groundwater wells that are part of the monitoring network were collected during a single day (on 6 September 2016) in order to evaluate the potentiometric surface and groundwater flow direction at the time of measurement. Following Geosyntec’s recommendation provided in the previous Semi-Annual Monitoring Report (Geosyntec, 2016a) submitted in May 2016, groundwater sample collection in September 2016 was performed using dual-membrane passive diffusion bags (PDBs). This recommendation followed the outcome of a Groundwater Sampling Methodology Comparison Study (Geosyntec, 2016b), which was appended to the May 2016 Semi-Annual Monitoring Report. This recommendation was verbally approved by Ms. Jaclynne Drummond of NCDEQ in a telephone discussion with Geosyntec, prior to commencement of the September 2016 groundwater sampling activities. Passive sampling of the Site wells with PDBs was employed in two mobilizations. During the first mobilization to the Site on 6 September, PDBs were deployed in each well at the approximate midpoint of the screened interval, or the midpoint of the water column if the screen was not fully submerged. Prior to deployment, each PDB was filled with laboratory-grade deionized water. PDBs were hung using a decontaminated stainless steel weight and stainless steel wire or disposable, inert cord. The PDBs were Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 4 11.2016 allowed to equilibrate within the wells for at least 21 days, providing time for constituents within the wells to diffuse across the PDB membranes, and to allow for vertical equilibration of constituents within the PDBs. During a second mobilization on 27 and 28 September, the water level and PDB depths were measured prior to sampling to confirm PDB placement. PDB samplers were recovered by pulling them up with the wire or cord. The bags were then pierced with a disposable, small-diameter discharge tube and water was transferred to the laboratory- provided sample containers. During retrieval, the PDB at DMW-B was found to be partially exposed above the water table (apparently as a result of a decrease in the water level), presenting the potential for VOCs to volatilize into the air above the water table. As a result, this well was sampled by purging and sampling with a bailer. After sampling, groundwater parameters (temperature, pH, and specific conductance) were measured with daily-calibrated multimeters from remaining water in the PDBs, or from bailed water if insufficient volume was available in the PDBs. Samples were transported to the laboratory on ice under chain-of-custody. Non-dedicated sampling equipment was decontaminated in accordance with procedures described in the WQMP. Field quality assurance/quality control (QA/QC) samples including a field (rinsate) blank, a trip blank, and a field duplicate (from parent sample DMW-06) were analyzed. Field data sheets for groundwater sampling efforts are included in Appendix A. 2.2 Surface Water Monitoring Surface water monitoring was conducted pursuant to procedures described in the WQMP. The surface water monitoring system consists of six sample locations (listed in Table 2 and depicted on Figure 2) on the three streams that cross the Site: Sugar Creek (SC), and two unnamed tributaries referred to as the north tributary (NT), and the south tributary (ST). Sample locations generally correspond to one upstream location and one downstream location from each stream. Laboratory analyses conducted for each surface water sample location are listed in Table 2. Surface water monitoring during the current reporting period was conducted on 27 through 28 September 2016 by Pace. Samples were collected from locations where flow was occurring (where possible) and from locations away from the stream bank to Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 5 11.2016 minimize disturbance to the stream bed. Samples were placed in laboratory-provided sample containers and transported to the laboratory on ice, under chain-of-custody. Field measurements of pH, specific conductance, and temperature were recorded for each sample at the time of collection. Field data sheets for surface sampling efforts are included in Appendix A. 2.3 Water Supply Wells Pursuant to the sampling schedule in WQMP (Table 2), annual sampling of water supply wells WSW-2 and WSW-3 was carried out on 28 September 2016. These wells are located adjacent to 6431 and 6505 South Tryon Street, respectively. Both of these samples were collected from exterior spigots on the side of each residence. 2.4 Methane Monitoring Methane monitoring was carried out pursuant to the LGMP. Methane monitoring activities include quarterly measurement of methane concentrations at methane probes, active extraction systems, and other points where methane could accumulate such as light poles and storm drains. Table 3 lists points that are the subject of quarterly or annual methane monitoring. Passive structures and Site features that are part of the methane monitoring program are depicted in Figures 3A and 3B. In addition to methane monitoring, methane alarm systems and active extraction systems are periodically inspected and maintained. Quarterly methane monitoring events during this reporting period were carried out by Geosyntec from 20 through 22 July and 19 through 20 October 2016. Inspection and maintenance of the three methane detection systems (located in the golf course clubhouse, golf course maintenance building, and baseball field concession building) was conducted by LEI Systems on 8 April 2016. These systems consist of about 40 Macurco GD-2A detectors connected to control panels and audible alarms which notify authorities and occupants in the event of methane detection. Additionally, stand-alone, plug-in Macurco GD-21 methane detectors are located in the Leatherman maintenance building, golf course chemical storage building, and baseball field ticket booth. Two plug-in First Alert Model GCO1CN methane alarms are located inside the John Crosland School.

Effluent methane concentrations, blower vacuum, air flow rates, and blower operating hours were recorded, where possible. Visual inspection of the landfill cap was conducted pursuant to the LGMP during quarterly monitoring events in July and October 2016. The purpose of the visual inspections is to identify areas of concern such as significant settlement, formation of subsurface voids, locations of methane venting, odors, distressed vegetation, or exposed waste.

MONITORING RESULTS The following sections describe the results of groundwater, surface water, and methane monitoring conducted during the current reporting period. 3.1 Groundwater 3.1.1 Potentiometric Surface Elevation and Groundwater Flow Direction Static groundwater elevations measured on 6 September 2016 are listed in Table 1, and historical groundwater elevations are listed in Table 4. Figure 4 displays a potentiometric surface map and inferred groundwater flow direction for the Site. Groundwater within the saprolite and shallow bedrock aquifer generally flows toward the southwest, following the surface topography toward Sugar Creek. The potentiometric gradient is approximately 0.013 ft/ft across the Site. The flow direction observed on 6 September 2016 was generally consistent with historical observations at the Site. Groundwater elevations were generally lower in September 2016 as compared to historical averages since 2006. 3.1.2 Groundwater Analytical Results A summary of detected constituents and field parameters (pH, specific conductance, and temperature) from monitoring well and water supply well samples collected during the September 2016 groundwater sampling event is included in Table 5 and laboratory analytical reports are included in Appendix B. Low levels of some volatile organic compounds (VOCs) and metals were detected in samples collected from Site monitoring wells in September 2016. Select compounds were detected in several wells at concentrations above the Title 15A North Carolina Administrative Code (NCAC), Subchapter 2L Standards (2L Standards). One or more VOCs exceeded their 2L Standard in 7 of the 18 groundwater monitoring wells sampled, and one or more metals were detected above their 2L Standard in 8 of the 18 wells sampled. No VOCs or metals were detected in water supply well samples collected during the September 2016 sampling event. Figure 5 displays a map with exceedances of the 2L Standard shown for each well. The September 2016 analytical results reveal the following: Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 8 11.2016  1,1-Dichloroethane was detected above its 2L Standard of 6 micrograms per liter (µg/L) in two wells, DDW-01 at 6.5 µg/L and DDW-02 at 11.4 µg/L.  1,2-Dichloropropane was detected above its 2L Standard of 0.6 µg/L in three wells, DDW-03 at 2.3 µg/L, DMW-01 at 2.5 µg/L, and DMW-06 at 2.0 µg/L.  1,4-Dichlorobenzene was detected above its 2L Standard of 6 µg/L in one well, DMW-01 at 7.0 µg/L.  Trichloroethene (TCE) was detected above its 2L Standard of 3 µg/L in four wells, DDW-01 at 3.1 µg/L, DDW-01A at 4.1 µg/L, DDW-03 at 4.2 µg/L, and DMW-06 at 4.9 µg/L.  Tetrachloroethene (PCE) was detected above its 2L Standard of 0.7 µg/L in three wells, DDW-01 at 6.7 µg/L, DMW-02B at 1.1 µg/L, and DMW-06 at 1.3 µg/L.  Vinyl chloride (VC) was detected above its 2L Standard of 0.03 µg/L in four wells, DDW-01A at 2.6 µg/L, DDW-03 at 3.0 µg/L, DMW-01 at 3.2 µg/L, and DMW-06 at 3.9 µg/L.  Barium was detected above its 2L Standard of 700 µg/L in one well, DMW-02A at 1,270 µg/L.  Cadmium was detected above its 2L Standard of 2 µg/L in one well, DMW-01 at 15.6 µg/L.  Iron was detected above its 2L Standard of 300 µg/L in six wells, with the highest concentration in YRW-10C at 116,000 µg/L.  Manganese was detected above its 2L Standard of 50 µg/L in five wells, with the highest concentration in DMW-01 at 23,100 µg/L. Historic groundwater analytical data are included in Appendix C. A statistical analysis of the monitoring well VOC data was performed to identify groundwater quality trends. The Mann-Kendall non-parametric test was performed on each performance monitoring well for each VOC with a concentration above the 2L Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 9 11.2016 Standard in September 2016. The Mann-Kendall test was utilized to evaluate whether or not the concentration of each VOC exhibits a statistically significant increasing or decreasing trend at a given confidence interval; for this evaluation, a confidence interval of 95% was applied. EarthScience Information Systems’ Esdat Version 5.1 software was used to perform the trend analysis. EPA guidance on statistical analyses for groundwater data has indicated that a concentration value lower than any of the detected measurements should be assigned when an analytical result is “non-detect” (EPA, 2009). Therefore, zero values were assigned to non-detects in this analysis. Table 6 presents the results of the trend analysis for VOCs. This analysis was performed on data collected since March 2008, which were readily available in the Site’s database. The results of the Mann-Kendall trend analysis are summarized as follows:  Fourteen (14) decreasing VOC concentration trends are considered statistically significant at 95% confidence, compared to one (1) upward trend.  PCE at DMW-02B was found to have a statistically significant increasing trend at a 95% confidence interval. The most recent PCE concentration in this well was 1.1 µg/L, compared to the 2L standard of 0.7 µg/L.  Two (2) VOCs were found to have no statistically significant trend at a 95% confidence interval. Decreasing concentration trends for the majority of VOCs exceeding the 2L standard provides statistical evidence of the overall improvement to the groundwater quality for VOCs at the Site as a result of natural attenuation processes. It is also noted that the single increasing trend (PCE at DMW-02B) has exhibited relatively low PCE concentrations ranging from non-detect to 1.6 µg/L since 2006. The presence of chlorinated daughter products of PCE (TCE, cis-1,2-DCE, and VC) in wells may indicate that some reductive dechlorination has occurred in Site groundwater, which can occur naturally under favorable (generally anaerobic) conditions. These biodegradation processes, in combination with other natural processes including Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 10 11.2016 sorption, dilution, and chemical degradation, contribute to natural attenuation of VOCs in groundwater and reductions in concentrations over time. Field parameter results were generally consistent with historical trends. pH values were measured within a range of 6.0 and 9.8, with the exception of DMW-02A, with a pH of 12.4. The pH at DMW-02A has typically been higher than other wells, which is potentially attributable to cement grout used in well construction. Specific conductance ranged from 79.8 to 1,588 microsiemens per centimeter (µS/cm), with the exception of DMW-02A (6,708 µS/cm) which has also exhibited high specific conductance historically. 3.2 Surface Water A summary of detected constituents and field parameters (pH, specific conductance, and temperature) from samples collected during the September 2016 surface water sampling event is included in Table 7, and laboratory analytical reports are included in Appendix B. Trace levels of barium were detected in all six surface water samples, at concentrations below its Title 15A NCAC Subchapter 2B Water Supply Standard (2B Standard) of 1,000 µg/L. Chromium was detected in surface water sample NT-1 at a concentration below its 2B Standard of 11 µg/L. No VOCs were detected in surface water samples during the September 2016 sampling event. Field parameter results were generally consistent with historical trends except specific conductance at the upstream SC-1 location, which was higher than typically observed at 1,750 µS/cm. Otherwise, pH ranged from 6.7 to 7.2 and specific conductance ranged from 91.8 to 246.3 µS/cm. 3.3 Methane Results of methane monitoring at locations with detections above 0.1% methane from January 2015 through October 2016 are summarized in Table 8, and landfill gas monitoring results from May 2016 through October 2016 at monitored locations are included in Appendix D. Table 8 and Appendix D include non-routine system performance assessment monitoring in the northeast boundary area which is not part of regular, quarterly monitoring. Historical landfill gas data from January 2012 through April 2016 is included in Appendix E. The following sections discuss these results. Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 11 11.2016 3.3.1 Passive Methane Monitoring Points Passive methane probe monitoring results from the most recent monitoring event (April 2016) are displayed in Figure 6 (northeast boundary) and Figure 7 (South Tryon Street). Methane concentrations at select subsurface monitoring probes exceeded the lower explosive limit (LEL) of 5% along the South Tryon Street boundary and northeast boundary during the July and October 2016 monitoring events. One LEL exceedance was observed in an off-Site probe at Leatherman Golf during this reporting period (8.1% methane in probe P-4 in October 2016). Since April 2011, five LEL exceedances have been observed in probes located across South Tryon Street (P-1 through P-4); three times at P-2 with a maximum methane concentration of 12.5%, and two times at P-4 with a maximum methane concentration of 8.1%. Although off-Site methane concentrations above the LEL were not detected along the northeast boundary, periodically elevated concentrations of methane at select probes indicate it is possible that off-Site migration of methane above the LEL may occur in the subsurface along the northeast boundary. Passive monitoring points in the vicinity of the John Crosland School (formerly the 5146 Ten Parkway Plaza Boulevard Building), located next to the northeast boundary, were monitored on a monthly basis during the current reporting period in response to past, occasional subsurface methane readings above the LEL in this area. Methane concentrations were not detected in the subsurface above the LEL in these probes during this reporting period. Methane monitoring alarms are located within the school, as discussed in Section 3.3.3. Construction of a supplemental landfill gas migration control system along the northeast boundary is planned in the first half of 2017. Methane was not detected above 25% of the LEL inside structures including buildings and storm drains monitored during this period. Five LEL exceedances were observed in the subsurface in the vicinity of light poles or scoreboards that are part of the monitoring program during this reporting period. Actions taken to address these locations are described in Section 3.3.4. 3.3.2 Active Extraction Systems 3.3.2.1 Golf Clubhouse System The golf clubhouse venting system utilizes a five-horsepower Rotron regenerative blower to extract methane from the clubhouse sub-slab gravel base using a combination Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 12 11.2016 of 31 horizontal, open-ended, PVC pipes grouped together into seven manifolds and eight vertical extraction points installed just below the building floor slab. In addition, nine vertical passive air infiltration vents are situated at regular intervals along the northern and southern sides of the clubhouse. These perforated pipes allow atmospheric air to be pulled into the subsurface to minimize pulling additional methane into the building from nearby landfill areas. The ability to pull in ambient air lessens the magnitude of the vacuum being applied to the surrounding soils and adds clean dilution air. The clubhouse venting system layout is shown in Figure 8. The clubhouse active extraction system was observed to be operating during both the July and October 2016 landfill gas monitoring events. The system was observed to be off on 7 June 2016, possibly following a power outage, and was restarted. Methane measurements from several points along the system that were recorded during landfill gas monitoring are included in Appendix D. Two exhaust fans located in the basement of the clubhouse were observed to be inoperable and were repaired and restarted in June 2016. 3.3.2.2 Northeast Boundary System The northeast boundary venting system utilizes a 7.5-horsepower Rotron regenerative blower, which removes methane vapors from an approximately 17-foot deep, 1,400-foot long interceptor trench originally installed in 1990. The trench was backfilled with gravel, and a bentonite/compacted soil cap was added to the top of the trench to help limit atmospheric air infiltration. A four-inch diameter corrugated, perforated pipe was installed in gravel, 3 to 4 ft above the base of the trench. Initially, four solid-walled, vertical PVC monitoring points (SU-0 to SU-3) were installed into or near the trench. An additional 4-inch diameter solid walled PVC bypass line was installed in July 1995 to address potential off-site methane migration in the northern portion of the trench. SU-4 was installed at this time as an access point to clean this line. The system was fitted with separate below grade valves that allow methane removal to be focused on the mid-northern section of the trench. In the fall of 2008, the City modified the system by installing six vertical extraction wells (SU-5 through SU-10) and two other converted vertical wells (SU-1 and SU-2). Valves were placed on each well to control and improve landfill gas extraction along the northeast landfill boundary. A condensate (moisture) drain was installed on 29 Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 13 11.2016 January 2009, to drain the excess water that accumulated due to the 2008 revision to the extraction system. The northeast boundary active extraction system was observed to be operating during both the July and October 2016 landfill gas monitoring events. The system was reported to the City as not operating by a passerby on 2 October 2016. Upon inspection, the blower was found to be inoperable. The 10-horsepower regenerative blower was replaced with a 7.5-horsepower regenerative blower (AMETEK-Rotron model number EN808BA72XL) on 11 October 2016 and the system was restarted. An hour meter which records operating time for the blower indicated less than one hour of downtime between the April and July 2016 monitoring events, and 90% operating time between the July and October 2016 monitoring events. Figure 9 displays the valve status, applied vacuum, air flow, and methane concentration at system vacuum extraction points as observed in October 2016, following replacement of the blower. This figure shows that the system is configured such that vacuum is focused on the middle section of the trench, which also corresponds to the highest methane concentrations historically measured within the trench. Air flow measurements were also taken at each active extraction well. The sum of the measurements indicates the total system air flow rate was approximately 283 standard cubic feet per minute (scfm) during the October 2016 monitoring event. The system flow rate and vacuum level are lower than during operation with the previous, larger blower. The observed flow rate is estimated to remove one trench pore volume at least every two hours, which allows for meeting operational objectives of preventing methane from migrating through the trench. Previous system evaluations have demonstrated that vacuum influence is not achieved outside of the gravel-filled trench. 3.3.3 Methane Detection Systems Methane detectors were confirmed to be active (by observation of a green status indicator light) by Geosyntec during quarterly landfill gas monitoring events. The results of inspection and maintenance of the three methane detection systems (golf course clubhouse, golf course maintenance building, and baseball field concession building) conducted by LEI Systems on 8 April 2016 showed that these systems were functioning properly. No alarms were reported from the plug-in methane detectors located within the softball ticket booth, Leatherman maintenance building, golf course chemical storage building, and the John Crosland School. Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 14 11.2016 On 7 June 2016, a methane alarm was triggered in the clubhouse. The alarm resulted in dispatching of the fire department, who monitored the indoor space and cleared it for occupancy. On inspection, it was found that the clubhouse blower system was not operating at the time of the alarm, which is suspected to be a result of a power outage. The clubhouse blower system was restarted following the alarm, and there were no additional alarms. 3.3.4 Landfill Cap Inspection and Repairs Visual inspection of the landfill cap was completed by Geosyntec during quarterly monitoring in July and October 2016. During July 2016 landfill cap inspections, surficial cracks and voids were identified at the bases of 17 light poles and scoreboards around the soccer and softball fields. Four locations (BLP-05, BSB-5, SLP-02, and SLP-05) were found to have subsurface methane concentrations above the LEL. These four locations, along with BSB-4 which had no methane detections but substantial settlement, were excavated to expose subsurface voids. Voids were filled with controlled low strength material (flowable fill) by Harvest Environmental Services, Inc. from 29 July through 3 August 2016. Table 9 summarizes these observations and repairs. During the October 2016 landfill cap inspections, surficial cracks and voids were noted at 15 light poles and scoreboards and methane was above the LEL at one location, BLP- 10. This location is within a locked portion of the facility and was cordoned off with caution tape. Ambient air readings in the vicinity of this light pole did not detect methane. In July 2016, some of the athletic fields at Renaissance Park (including the softball and soccer facilities) were closed to public use. Mecklenburg County Park and Recreation reported that ongoing settlement of the former landfill affected upkeep of the fields. Future decommissioning of field infrastructure, such as lighting, is under discussion. 4. SUMMARY, CONCLUSIONS AND RECOMMENDATIONS The following sections summarize findings and conclusions based on data collected during the second half of 2016, and historical data collected at the Site. Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 15 11.2016 4.1 Groundwater  Groundwater elevations were generally lower than elevations observed in recent years during the September 2016 groundwater monitoring event, and were within historical ranges.  Groundwater flow at the site was generally consistent with historical observations, with a primary flow direction to the southwest toward Sugar Creek.  Relatively low levels of VOCs were present in Site groundwater during monitoring conducted in March 2016. One or more VOCs exceeded their 2L Standard in 7 of the 20 wells sampled. VOCs exceeding the 2L Standard in at least one Site well were 1,1-dichloroethane, 1,2-dichloropropane, 1,4-dichlorobenzene, TCE, PCE, and VC.  Low levels of metals were present in Site groundwater during monitoring conducted in March 2016. One or more metals were detected above their 2L Standard in 8 of the 20 wells sampled. Metals exceeding the 2L Standard in at least one Site well were barium, cadmium, iron, and manganese.  A trend analysis of groundwater VOC data since 2008 indicated that decreasing trends are present for 14 of 17 VOC constituents exceeding the 2L standard. These trends provide evidence that natural attenuation processes are reducing groundwater VOC concentrations at the Site. 4.2 Surface Water Barium was detected in all six surface water samples at concentrations below its 2B Standard and Chromium was detected in one surface water sample below its 2B Standard. No VOCs were detected in surface water samples collected in September 2016. 4.3 Methane  Methane was not detected above 25% in monitored structures during the reporting period. Methane was detected above the LEL in the subsurface in cracks and/or voids beneath five light poles during this monitoring period. Semi-Annual Monitoring Report – Second Half 2016 Former York Road Landfill, Charlotte, North Carolina November 2016 GC5699A\DRAFT 2016 Nov York SAR.docx 16 11.2016 These voids were either filled with flowable fill or cordoned off in a secured area.  Methane concentrations at select subsurface monitoring probes exceeded the LEL along the South Tryon Street boundary and northeast boundary.  Methane concentrations in off-Site subsurface monitoring probes near the northeast boundary remained below the LEL during this reporting period. Methane concentrations were above the LEL at one off-Site probe (P-4) near the Tryon Street boundary. 4.4 Future Work Efforts to address occasional subsurface methane migration at the northeast boundary are ongoing. Construction of a supplemental landfill gas migration control system along the northeast boundary is planned for 2017. Off-Site LFG monitoring location P-4, located across South Tryon Street from the Site, will continue to be monitored following the LEL exceedance observed in October 2016. If off-Site LEL exceedances continue, the City will evaluate measures to mitigate methane in this area. At the City’s request, Geosyntec has prepared an updated monitoring plan for the Site which will combine the groundwater sampling plan and landfill gas monitoring plan into a single document, and update monitoring procedures. This document is planned to be submitted to NCDEQ prior to conducting 2017 monitoring activities.
