North Carolina Department of Environmental Quality Solid Waste Section 1646 Mail Service Center Raleigh, NC 27699-1646 RE: Harrisburg Road Landfill SVS/SEMS Results Harrisburg Road Closed MSW Landfill (Permit No. 60-01) Charlotte, North Carolina Dear Ms. Drummond: Smith Gardner, Inc. (S+G) is pleased to present the results from the soil vapor surveys (SVS) performed at the Harrisburg Road Closed MSW Landfill (Permit 60-01) and current Charles T. Myers Golf Course. The soil vapor surveys were requested by the County due to development around the landfill, elevated landfill gas (LFG) concentrations in some existing piezometers, and areas of apparently distressed vegetation on the golf course. This report presents the data collected by S+G personnel over three events (November 17-18, 2020, November 24, 2020, and June 3-4, 2021). SITE HISTORY Site Development The site was constructed as an area fill landfill with discreet units dating from the 1970's through the early 1990's. The units were used for the disposal of municipal solid waste (MSW), construction and demolition debris (C&D), as well as a separate coal ash disposal unit. The site was filled and graded with the knowledge that it would be used as a golf course post -closure and therefore does not consist of one large fill area, but has discrete fill areas around the site. The site is actively used as the Charles T. Myers golf course, the golf course has multiple water features including five ponds and multiple small unnamed tributaries of Reedy Creek across the property. Adjacent to the golf course is the Hickory Grove Recycling Center. Landfill Gas Monitoring/Collection The golf course clubhouse, maintenance shop and recycling center are equipped with permanent continuous landfill gas monitoring devices which are inspected monthly along with probe monitoring at the site. Other structures include outbuildings to the clubhouse, which do not have permanent monitoring systems. DocuSign Envelope ID: 3C87DEEE-0544-4397-BOB5-DABBF9CBE8E7 Ms. Grzymski April 15, 2022 Page 2of5 The site has an active LFG collection system located at the recycling center, which includes sub -slab landfill gas extraction and passive venting through roof vents at the recycling facility. At the golf course, in areas beyond the likely influence of the LFG collection system, there are areas of distressed vegetation due to LFG concentrations in the root zone. LFG monitoring wells at the recycling center also indicate elevated concentrations of LFG adjacent to the Harrisburg Road landfill. SUMMARY OF FIELD ACTIVITIES The following summarizes the field activities performed during this scope of work. Utility Mark -Out GPRS, Inc. was contracted to perform utility locating services prior to all field events. Utility locating was performed using a combination of an underground scanning GPR antenna and an electromagnetic pipe and cable locator. GPRS and S+G personnel mobilized to the site November 17, 2020 and used a Trimble GPS unit to locate all 35 proposed SVS probe locations. A roughly 10' x 10' square, centered on the proposed probe location, was then marked and scanned by GPRS for underground utilities or other anomalous objects. Although a few probe locations did contain an underground utility or other anomaly within its 10'x10' footprint, no proposed SVS probe locations had to be moved due to an obstruction. GPRS and S+G personnel mobilized to the site June 3, 2021 to mark where utilities exit the site property since these could provide potential migration pathways for landfill gas. Underground utilities were found to exit the property from three locations: the golf clubhouse, the maintenance building in the south east corner of the site, and the recycling center. Underground utilities found at each location are as follows: • Clubhouse - Power, communications, and water; • Maintenance - Water and gas; • Recycling center - Water and communications. Gas was not connected to the clubhouse nor the recycling center. However, the recycling center does have a gas line connected to an on -site propane tank. Power was fed to the recycling center and maintenance building via above head poles and communication lines were fed to the maintenance building via above head poles. All buildings on site are on septic systems and do not connect to city sewer lines. All probe and utility locations are shown on Figure 1. Soil Vapor Survey Due to heavy rain the week prior to the first soil vapor survey, and concern that nearly saturated vadose zone conditions may have biased the gas readings, a second survey DocuSign Envelope ID: 3C87DEEE-0544-4397-BOB5-DABBF9CBE8E7 Ms. Grzymski April 15, 2022 Page 3of5 was conducted the following week. The second survey was conducted to spot check locations closest to the property line to confirm the readings detected in these probes during the first event. Across all events, S+G personnel conducted the soil vapor survey by advancing 1/2- inch diameter metal rods into the subsurface by hammer drill. Efforts were made to drive the probe rods between 7-9 feet into the subsurface, however, probe refusal was routinely reached around 6 feet below grade. A total of 41 probes (35 during the November 2020 events at predetermined locations, and 6 during the June 2021 events at locations adjacent to public utility lines, were advanced during field events and actual depths of these ranged between 5.5 — 9 feet below grade. After reaching probe refusal, a standard high -lift jack was used to extract the probe rods from the ground. After extraction, A GEM 5000 gas analyzer was used to measure methane, carbon dioxide, hydrogen sulfide, and oxygen from the probe We, measuring from the bottom to the top to evaluate the entire probe depth. Surface Emissions Scan A surface emissions scan was performed at the Harrisburg Road Closed MSW Landfill on June 4, 2021 near the property boundary as well as drains, cracks, and other locations that may provide a conduit for gas migration. Nine distinct areas of distressed vegetation (SEM-1 through 9) were identified across the site and were included in the surface emission scan. The scan was performed using a Thermo Scientific TVA 2020 FID gas analyzer to measure the concentration of methane, in parts per million (PPM), at the soil surface. Readings were recorded at 5-second intervals while moving in a serpentine pattern in all sampled areas. Surface emission scan areas are shown on Figure 2. RESULTS Over all sampling events and across all41 SVS locations, 12 locations indicated concentrations of methane at >5% (or >100% of the Lower Explosive Limit) (SVS-2, SVS-4, SVS-16, SVS-18, SVS-19, SVS-22, SVS-23, SVS-30, SVS-32, SVS-33, SVS-34, and SVS-35). These locations are circled on Figure 1 and results are summarized in Table 1. Property Line Exceedances Of the 12 locations with >5% methane concentrations, three are located between the landfill and the property line. Two of these (SVS-2 and SVS-4) are located between the landfill and Pence Road and one (SVS-16) is located near the northern property line, between the landfill and what appears to be an overhead utility corridor based on aerial photography. Of the six soil vapor samples taken adjacent to underground utilities leaving the site property, none exhibited methane exceedances. Probes SVS-2 and 4 are located between the landfill units and the rail road track adjacent to Pence Road. There is an apartment complex between the railroad and Pence Road. Based on measurements made in Mecklenburg County's Polaris 3G GIS system, it appears the nearest DocuSign Envelope ID: 3C87DEEE-0544-4397-BOB5-DABBF9CBE8E7 Ms. Grzymski April 15, 2022 Page 4of5 building is approximately 100 feet from SVS-2 while SVS-4 is located approximately 192 feet from the nearest building. Permanent LFG probes (P-5, P-6, P-7, P-8, P-9A, and P-913), positioned closer to the off -site buildings have been monitored quarterly since 2012. No methane exceedances have been detected in those permanent probes since the start of monitoring. Historical permanent LFG probe data is included as Table 2. Probe location SVS-16 is located between the landfill unit and an apparent utility corridor. Across the corridor are soccer fields and a parking lot. Based on Polaris GIS measurements we estimate the nearest edge of the soccer field and parking lot to be approximately 225 feet from SVS-16. Landfill Interior Exceedances The remaining nine locations exhibiting >5% methane are located within the landfill cell. It should be noted that the results from SVS-31 are suspect due to its location within the landfill and the high concentrations of methane detected in the surrounding probes, including the probe located near the property line in this area. Probe SVS-19 is located approximately 100 feet from the golf course club house which is a potential receptor. It is also approximately 70 feet from a clubhouse outbuilding, another potential receptor. As mentioned above, the clubhouse has a permanent landfill gas monitoring system. Surface Emissions Scan During the surface emission scan, the highest reading recorded was 317 ppm or 0.0317% occurring at SEM-3. For the majority of the site scanned, methane concentrations remained between 0-1 ppm. Nine areas of distressed vegetation displayed elevated methane concentrations: SEM-1, 2, 3, 4, 5, 6, 7, 8, and 9. Results are shown on Figure 2 and raw data from the TVA can be found in Table 3. Landfill gas migration appears to be occurring in isolated areas at the site. Four areas of elevated methane concentrations near potential receptors have been identified. Two of these are located near the railroad tracks (SVS-2 and SVS-4). Additionally, a probe located near the golf course club house (SVS-19) exhibits elevated methane concentration. Finally, the probe located near the northern property line (SVS-16) also exhibits elevated landfill gas concentrations. RECOMMENDATIONS Based on these sampling events, we make the following recommendations: 1. Previously installed soil vapor probes P-5 through P-9b, which have a long history of non -detectable LFG concentrations, should continue to be monitored on a quarterly basis to continue to evaluate potential migration in this area. DocuSign Envelope ID: 3C87DEEE-0544-4397-BOB5-DABBF9CBE8E7 Ms. Grzymski April 15, 2022 Page 5of5 2. An additional permanent probe should be installed between the railroad track and Pence Road at P-11 to determine if methane is migrating to the property line in this area. 3. Continue to maintain and monitor permanent landfill gas detectors in the club house, recycling center and the maintenance shop. 4. Any occupied structures on the property without permanent landfill gas detectors (Scale house, recycling station attendant building, southeast maintenance shop, golfcart shop, and the golf learning center) should have a landfill gas monitoring plan developed and should be included in monthly monitoring.
