RE: Landfill Gas Monitoring – Second Quarter 2013
Piedmont Landfill and Recycling Center, Permit 34-06
JOYCE Project No. 392.1301.12, Task No. 03

Dear Ms. Drummond:

Landfill gas monitoring for the closed Piedmont Landfill and Recycling Center was
conducted by Joyce Engineering on April 17, 2013. The Environmental Monitoring Reporting Form
(EMRF) and Monitoring Data Log of the results are attached for this second quarterly event.
Methane was detected in gas probe GP-10 above the LEL on this date. Methane has been previously
detected in GP-10 over the limit, but the methane has been attributed to migration from close
proximity of the Kernersville Landfill that is unlined. Piedmont Landfill and Recycling Center will
continue monitoring landfill gas on a quarterly basis, with the next event scheduled in July 2013. If
you have any further questions, please contact me or Van Burbach at [phone]. Thank you.

Sincerely,
JOYCE ENGINEERING
