Re: Contaminant Delineation Plan for the Active Phase I Landfill
Highway 49 C&D Landfill
Cabarrus County
Solid Waste Permit Number 1306
DIN 25943

Dear Mr. Griffin:

The Solid Waste Section has completed a review of the Contaminant Delineation Plan for the Active Phase
I Landfill dated March 21, 2016 (DIN 25942) and submitted on behalf of Greenway Waste Solutions of
Harrisburg, LLC by CEC, Inc. for the Highway 49 C&D Landfill, Solid Waste Permit Number 1306. The plan
was submitted in response to confirmed exceedances of the Appendix I constituents, specifically volatile
organic compounds and in accordance with 15A NCAC 13B .0545. Assessment monitoring has been
conducted since 2013.

Within the Contaminant Delineation Plan for the Active Phase I Landfill, additional groundwater and vapor
phase assessment is recommended to evaluate the groundwater impacts. Also, a request is proposed to
discontinue monitoring for Appendix II of 40 CFR Part 258 semi-volatiles, herbicides, pesticides, and PCBs.

As a result, the Contaminant Delineation Plan for the Active Phase I Landfill is approved at this time with
one exception. Because the contaminant plume has not been completely delineated horizontally and
vertically and Appendix II of 40 CFR Part 258 constituents have been detected periodically within the
groundwater monitoring wells since 2013, 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,
