FACILITY COMPLIANCE INSPECTION REPORT Division of Waste Management Solid Waste Section Page 2 of 3 ADDITIONAL COMMENTS 1. The facility ceased operations on October 7, 1993. 2. A gate was located at the entrance to the site to prevent unauthorized access. 3. The landfill was stabilized with native vegetation which was well maintained. 4. Edge-waste-markers consisting of white, PVC poles were in place at the time of inspection. 5. Semiannual groundwater monitoring was being performed. Records for 1st and 2nd semiannual sampling events for 2016 through 2020 and the 1st semiannual sampling event for 2021 were verified via the Division of Waste Management Document Database. 6. Methane monitoring was being performed quarterly as required. x Gas exceedances had been documented above the lower explosive limit for methane at GP-1 during multiple sampling events in the past. Wilkes County has taken multiple steps to address the methane exceedances at GP-1. x A Landfill Gas Remediation Plan was submitted on February 18, 2015. The plan proposed to remove the cap from a nearby passive landfill gas vent and install a solar powered turbine on the vent. Inspection of the facility on April 17, 2015 found the solar powered turbine had been installed as proposed. x A revised Landfill Gas Remediation Plan was submitted to the Solid Waste Section on August 10, 2018 and approved on August 13, 2018. This plan proposed installation of a gas intercept trench between the landfill and GP-1. Three perforated risers were to be installed at approximately 40-foot intervals in the trench. The gas intercept trench was installed in October 2018. x In early October 2019, the County installed solar turbine caps on the three vents located within the intercept trench, and on the next nearest gas vent in the waste (GV-2). No exceedances above applicable standards were observed during the 4th quarter monitoring event for 2019. x Exceedances above the lower explosive limit for methane were once again observed during the 1st and 2nd quarter monitoring events for 2020. As a result, a revised Landfill Gas Remediation Plan was submitted to the Solid Waste Section on May 26, 2020 and approved the same day. The plan proposed installation of a temporary gas extraction unit on the risers within the gas intercept trench and then conducting a pilot test to determine if applying a stronger vacuum to the trench will improve its effectiveness. x On March 30, 2021, the vents located within the gas intercept trench were connected to the existing gas extraction system via aboveground corrugated piping. 2nd, 3rd, and 4th, quarter monitoring events found no exceedances above applicable standards at all gas probes on site. x During the inspection on December 21, 2021, Ms. Byrd explained the County plans to bury the piping leading from the intercept trench to the gas extraction system to protect the lines and allow for this area to be mowed. 7. No areas of significant settling were observed. 8. No erosion was observed. 9. No standing water or evidence of standing water was observed on top of the landfill. 10. One small tree was observed near SV-5. Ms. Byrd and Mr. Wolfe stated the tree would be removed from the landfill. 11. The following groundwater monitoring wells were observed on site: Well # Concerns/Comments MW-1 Erosion observed under concrete pad. Need to repair. MW-2 No concerns MW-3 Need to remove soil from top of concrete pad. MW-4 Need to remove soil from concrete pad. Needs a metal tag. MW-5 Could not determine if concrete pad provided. May be covered with soil. Please confirm. Tree growing into steel casing. Ms. Byrd and Mr. Wolfe said tree would be removed. Needs a new lock.
