Subject:Comments on the permit application, proposed Union Cross Land Development LCIDLF
Dear Mr. Boyles:

The Solid Waste Section completes a review of the permit application for the new LCIDLF and has several
comments stated below:

1. According to deed search, the property where the proposed landfill is owned by Tucker Trace Farms
LLC, not Elizabeth Ann Tucker. Please conduct the following actions:
a. Provide a copy of the latest property deed document issued by Forsyth County Register of Deeds.
b. Make necessary revision/update on the submitted drawings and application forms.

2. According to the Special Use Permit- F1575 issued by City Winston-Salem/Forsyth County Planning
Board, the proposed landfill site is located within Abbotts Creek WSIII Watershed, a public drinking
water resource; therefore, a “WATERSHED PLAN PERMIT” is required as a portion of the permit
application. Please provide a copy of the permit.

3. Please provide the soil logs of the Test Pit # 2, 3, & 4 as shown drawing Sheet C-1. The log of each test
pit should report, at a minimum, the depth of test pit, soil types, and water table elevation, if
encountered.

4. Regarding the high-water table (SHWT) at this site, please address the following concerns:
a. Operational Requirement Note No. 1 in drawing Sheet C-1 note field states that the seasonal high-
water table (SHWT) is 878 feet above mean sea level (amsl). Please provide narratives how the
SHWT is concluded/determined.

b. If the SHWT of 878 feet amsl is confirmed and the landfill base elevations ranging from 886 to
893.5 feet amsl, as shown drawing Sheets C-3 through C-5 will be established by excavation and
regrading. Please describe the as-built survey requirements/assistance to confirm the landfill base
construction.

5. Item 6. of the Operations Plan in drawing Sheet C-1 note field states that the landfill facility will receive
uncontaminated soil for disposal. The uncontaminated soil
a. must be an un-contamination earthen material and meet the “unrestricted use standards" - meaning
contaminant concentrations for each environmental medium that are acceptable for all uses per
NCGS 130A-310.65; and

b. shall have any contaminant with a concentration less than or equal to that in the NC Residential
Health Base Preliminary Soil Remediation Goal (NC PSRG) which can be found in the web link:

_FINAL.pdf
Please add the requirements to the revised application document. The copy of NC PSRG (Residential
Health Base) must be appended to the Operations Plan.

6. Please provide the maximum extent (in acreage) for each of the proposed recycling unit – Wood Waste
Collection Area, and Concrete Process Area.
Please contact me if you have any questions of the comments.
