Re: Contaminant Delineation Plan for the Closed Phase I C&D Landfill
North Mecklenburg Closed Phase I C&D Landfill
Mecklenburg County
Solid Waste Permit Number 6013
DIN 25969

Dear Mr. Griffin:

The Solid Waste Section has completed a review of the Contaminant Delineation Plan for the Closed Phase I
C&D Landfill dated March 21, 2016 (DIN 25968) and submitted on behalf of Greenway Waste Solutions of
Harrisburg, LLC by CEC, Inc. for the North Mecklenburg Closed Phase I C&D Landfill, Solid Waste Permit Number
6013. The plan was submitted in response to confirmed exceedances of the Appendix I constituents,
specifically volatile organic compounds. An assessment was initiated in 2013 (DINs 19487 and 19520).

Within the Contaminant Delineation Plan for the Closed Phase I C&D Landfill, additional groundwater and vapor
phase assessment is recommended to evaluate the observed groundwater impacts. The recommendations
include:
• Evaluation of additional analytical leachate/landfill gas ‟indicator” parameters as a part of routine
landfill monitoring to characterize the source of the groundwater impacts;
• Evaluation of the active landfill gas extraction system in the closed Phase I C&D Landfill as an effective
interim groundwater remedy; and
• Development of a screening numerical model to simulate contaminant fate and transport to further
evaluate risk associated with the migration of groundwater contaminants.

As a result, the Contaminant Delineation Plan for the Closed Phase I C&D Landfill is approved 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.
