Box 1486 Morganton, NC 28680 RE: Burke County, East Burke Landfill, Permit Number 12-02 Landfill Gas Monitoring Report – Third Quarter 2017 JOYCE Project No. 277.1801.12, Task 04 Dear Mr. Champion; The purpose of this letter is to provide you with the results for the third quarter 2017 landfill gas monitoring event at the closed East Burke Landfill. Gas probes GP-1, GP-1B, GP-2, GP-3, GP-4, GP-5, and GP-6, which were installed in June 2015, were monitored on June 26, 2017. During the September 2017 monitoring event, methane was detected above the lower explosive limit (LEL) in gas probes GP- 1, GP-3, and GP-4. No exceedances were recorded for any of the other probes. These results are consistent with previous results. Tables 1 and 2 summarize the methane detections and exceedances for this event, and the attached Landfill Gas Monitoring Log presents the more detailed results. A site map showing the gas probe locations is also attached. 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. A Landfill Gas Remediation Plan for this facility was submitted on September 14, 2015, and was approved on September 18, 2015. As proposed, the three passive landfill gas vents were installed on the site on May 19, 2016. The next quarterly monitoring event is tentatively scheduled for December 2017. If we can provide any additional information, please do not hesitate to call me at (336) 323-0092. Sincerely, JOYCE ENGINEERING Van Burbach, Ph.D., P.G.
