RE: Landfill Gas Monitoring Report
LFG Monitoring – March 2015
Town of Kernersville Closed Landfill, Permit No. 34-04
JOYCE Project No. 838.1501.12, Task No. 03

Dear Ms. Drummond:

Please find the attached Environmantal Monitoring Reporting Form (EMRF) and Landfill Gas
Monitoring Log for the monthly monitoring event that occurred on March 16, 2015, at the Closed Town of
Kernersville Landfill (Permit number 34-04). Methane monitoring for this event was conducted by Joyce
Engineering (JOYCE) on behalf of the Town of Kernersville in accordance with the approved Landfill Gas
Monitoring Plan dated July 17, 2012. Methane was detected in gas monitoring wells GW-1, GW-2R and
GW-8 above the Lower Explosive Limit (LEL) during this monitoring event.

During this event three probes belonging to the adjacent Waste Management Piedmont landfill GP-9,
GP-10, and GP-11 were also monitored for methane gas. Methane was detected in GP-10 above the Lower
Explosive Limit (LEL) during this monitoring event

Additional monthly monitoring will provide additional data to demonstrate whether the methane
migration is being reduced by the three passive vents installed on the Kernersville Landfill in November
2013. A map has been included with this report to illustrate the proximity of the two landfills and the
locations of the gas probes. If you have any further questions, please contact me or Van Burbach at (336)
323-0092. Thank you.

Sincerely,
JOYCE ENGINEERING
