RE: 2015 FOURTH QUARTER LANDFILL GAS MONITORING
PIEDMONT LANDFILL & RECYCLING CENTER
JOYCE PROJECT NO. 392.1501.12, TASK 02

Dear Al:

Attached to this letter is the landfill gas migration monitoring results for the Fourth
Quarterly monitoring Event of 2015 at the Piedmont Landfill in Kernersville, North Carolina.
Ten permanent gas probes, eighteen bar-hole probes, and one on-site structure were monitored
on October 6, 2015. Gas Probe GP-10 was exempted from the compliance monitoring network
in a letter from North Carolina Department of Environment and Natural Resources (DENR) –
Solid Waste Section dated January 21, 2014. There was no exceedence of the LEL in the
compliance network or on-site structure. The results are presented on the NC DENR format
Landfill Gas Monitoring Data Form dated October 6, 2015. The Piedmont Landfill monitoring
results were also uploaded to the WM LGMS on October 6 . NC DENR notification is not
required at this time based on no detections of methane and no exceedences of the Lower
Explosive Limit (LEL) in the compliance monitoring locations during the event.

A copy of this report should be kept on file for the facility. If you require anything else
please let me know [phone], or contact Mousa Maimoun at (704)-837-2005.

Sincerely,
JOYCE ENGINEERING
