Box 219 Morganton, NC 28680 RE: Burke County, John’s River Landfill Permit Number 12-03 Third Quarterly Landfill Gas Monitoring Report of 2016 JOYCE Project No. 277.1601.12, Task 04 Dear Mr. Hollifield; The purpose of this letter is to provide you with the results for the August 23, 2016, (third quarter) monitoring event at the John’s River Waste Management Facility. Methane was detected above the lower explosive limit (LEL) in gas probes GP-2S, GP-2I, and GP-2D. Gas probes GP-2S, GP-2I, and GP-2D are a nested set and are not boundary probes. They are located in close proximity to waste and the detection of landfill gas is expected. The concentrations are similar to those detected during previous events. Gas probes GP-4, GP-5, and GP-6 were installed on September 2, 2014 to monitor the Phase 1A cell. Methane was detected in GP-4 above the LEL. GP-4 is located between the old C&D-over-MSW landfill and the Phase 1A area, and is not a boundary probe. The methane is more likely from the old landfill than Phase 1A. The passive gas vents GV-1 through GV-7, temporary gas probes TGP-1 through TGP-10 (excluding TGP-3 and TGP-6 which were destroyed), and selected wells and piezometers were also monitored and the results are attached. Exceedances of the LEL for methane were noted in the passive gas vents, as expected, and in TGP-1, TGP-2, TGP-4, and TGP-9. Methane was detected in MW-36 above the LEL. None of these are considered to be boundary probes. No exceedances were recorded for any of the other probes, monitoring points, or structures. The methane detections and exceedances are summarized in Tables 1 and 2, respectively. The landfill gas monitoring logs are also attached. A site map showing probe and monitoring point locations is also attached. Mr. Chris Hollifield May 24, 2016 Page 2 of 2 We have included an EMRF and will forward a copy of this report to Jaclynne Drummond with the NCDEQ Solid Waste Section. This report should be added to the facility’s records. If we can provide any additional information please do not hesitate to call Van Burbach or me at (336) 323-0092.
