RE: Landfill Gas Monitoring Report
Monthly LFG Monitoring Event for March 2017
Town of Kernersville Closed Landfill, Permit 34-04
WithersRavenel Project No. 06140180.11
Dear Ms. Drummond:
Attached are a Monthly Landfill Gas Monitoring Report and an Environmental Monitoring Reporting
Form (EMRF) for the monthly monitoring event that was conducted on April 7, 2017 by WithersRavenel.
Inc. at the Town of Kernersville Closed Landfill (Landfill), Permit 34-04. This event was conducted on
behalf of the Town of Kernersville (Town) in accordance with the approved Landfill Gas Monitoring
Plan, dated July 17, 2012.
As in past monitoring events, methane monitoring was planned to be conducted in the eight landfill
gas (LFG) probes located on the Town’s property (designated GW-1 through GW-8) and three LFG
probes shared with the Waste Management Piedmont Landfill (designated GP-9 through GP-11).
Access to the locked security fences and the LFG probes located inside (GW-8, GP-9, GP-10 and GP-
11) was not gained in time to be included with this sampling event. Instead, Waste Management
allowed Joyce Engineering to provide the Town with a copy of their 2017 First Quarter Landfill Gas
Monitoring Report, Piedmont Landfill & Recycling Center, for the site located across the street from
the Town’s closed Landfill. Joyce’s readings for LFG probes GP-9, GP-10 and GP-11 have been included
and annotated on the attached Monthly Landfill Gas Monitoring Report.
As shown on the attached Report, methane gas was not detected in five of the seven LFG probes
monitored by WR on April 7, 2017. Elevated levels of methane gas were detected in concentrations
above the Lower Explosive Limit (LEL) in GW-1 and GW-2R, and reported by Joyce in GP-10.
WithersRavenel, on behalf of the Town of Kernersville, appreciates the opportunity to submit this
report to the Solid Waste Section. Please contact me with comments, questions, or requests.
Sincerely
WithersRavenel
Mark Brown, LG, PG, RSM
Senior Geologist
