Mr. John Murray, P. E.
Regional Engineer
Division of Waste Management / Solid Waste Section
North Carolina Department of Environmental Quality
400 Commerce Ave
Morehead City, North Carolina 28557
[e-mail]

Subject: Leachate Storage Facility for the Great Oak Landfill
Randolph County
Solid Waste Permit Number: 7607-MSWLF-2015

Dear Mr. Murray:

On behalf of Waste Management of Carolinas, Inc., SCS Engineers, PC is submitting the
attached drawing package to construct a new Leachate Storage Facility at the Great Oak Landfill.
This drawing package is being submitted to elaborate on the previous North Carolina
Department of Environmental Quality (NC DEQ) approved leachate management system
submitted as part of the landfill permit application completed by S&ME.

Leachate from the new storage facility will be conveyed and treated by the City of Asheboro.
The expected average flow from the storage facility is 50 gallons per minute (gpm) with a peak
of 80 gpm.
A general description of the proposed project consists of constructing a 250,000 gallon
aboveground leachate storage tank and concrete secondary containment with the possibility to
install an additional 250,000 gallon tank in the future. The necessary piping, valves and controls
are included in the project.
If you require additional information or have questions about the project, please contact Albert
Glenn at [phone] or Terry Darragh with Waste Management at [phone].
Sincerely,

Albert D. Glenn, P.E.
Project Manager
SCS ENGINEERS, PC

Mr. John Murray, P. E.
