Re: Assessment Monitoring Report
Appendix II Monitoring Request
Old Salisbury Road (OSR) C&D Landfill
Forsyth County
Solid Waste Permit Number 3412
DIN 26033

Dear Ms. McHargue:

The Solid Waste Section has completed a review of the Assessment Monitoring Report dated January 2016
(DIN 26032) and submitted on behalf of Winston-Salem City/County Utilities Commission for the Old
Salisbury Road C&D Landfill, Solid Waste Permit Number 3412. Assessment monitoring was initiated at
the landfill in 2012 (DINs 15819 and 15916), and a monitoring request was approved in February 2014
(DINs 20378, 20550, and 20581).

Within the Assessment Monitoring Report, the Winston-Salem City/County Utilities Commission is
requesting the following: to discontinue monitoring for Appendix II of 40 CFR Part 258 constituents that
have not been detected since November 2012; to add all Appendix II of 40 CFR Part 258 constituents that
were detected above the Solid Waste Section Limit (SWSL) since November 2012; and to add all Appendix
II of 40 CFR Part 258 volatile organic compounds that have been detected since November 2013.

As a result, the monitoring requests within the Assessment Monitoring Report are approved as described
at this time with one exception. Because the contaminant plume has not been completely delineated and
Appendix II of 40 CFR Part 258 constituents have been detected within the groundwater monitoring wells
since 2012, please continue to conduct the full suite of Appendix II of 40 CFR Part 258 constituents at this
time. If you have any questions regarding this letter, please feel free to contact me at 828.296.4706 or by
email at [e-mail]. Thank you for your continued cooperation with this matter.

Sincerely,
