RE: 2016 SECOND 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 second
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
April 5, 2016. 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 April 5, 2016. The Piedmont Landfill monitoring results were also uploaded to
the WM LGMS on April 5, 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 let me know [phone], or contact Mousa Maimoun at (704)-837-2005.

Sincerely,
JOYCE ENGINEERING
