RE: 2016 FOURTH QUARTER LANDFILL GAS MONITORING
PIEDMONT LANDFILL & RECYCLING CENTER
JOYCE PROJECT NO. 392.1601.12, TASK 02

Dear Al:

Attached to this letter is the landfill gas migration monitoring results for the fourth
quarterly monitoring event of 2016 at the Piedmont Landfill in Kernersville, North Carolina.
Ten permanent gas probes, eighteen bar-hole probes, and one on-site structure were monitored
on December 19, 2016. The bar-holes are located around the western site perimeter to provide
coverage between permanent Gas Probes. Gas Probe GP-10 was exempted from the compliance
monitoring network in a letter from North Carolina Department of Environmental Quality
(NCDEQ) – 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 NCDEQ format
Landfill Gas Monitoring Data Form dated December 19, 2016. The Piedmont Landfill
monitoring results were also uploaded to the WM LGMS on December19, 2016. NCDEQ
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 call me at [phone], or contact Mousa Maimoun at (704)-837-2005.

Sincerely,
JOYCE ENGINEERING
