Dynatech Properties and Red Carpet Inn Brownfields Property
Charlotte, Mecklenburg County
Brownfields Project No. 25001-21-060, 25067-21-060 and 23070-19-060

Mr. Ellerbe and Mr. Cullum,

The North Carolina Department of Environmental Quality (DEQ) Brownfields Program received
and reviewed a request to export approximately 1,500 cubic yards of soil from Dynatech
Brownfields Properties to Red Carpet Inn Brownfields Property. This request was submitted on
your behalf by Ms. Haley Martin of Hart & Hickman (H&H) in her email dated May 13, 2022,
titled 25001& 250067- Dynatech- Soil Export Request. DEQ understands the redevelopment on
the Dynatech II Brownfield Property (25001-21-060) and Dynatech III Brownfields Property
(25067-21-060) will be done jointly under the DEQ-approved Environmental Management Plan
(EMP) dated January October 19, 2021.

DEQ Brownfields reviewed the analytical data and site maps provided in the correspondence. The
request is to export up to 1,500 cubic yards of soil from the Dynatech Brownfields Properties
from sections FCC-2B (12-18 feet below ground surface [ft bgs]), FCC-3A/3B (4-14 ft bgs),
FCC-4A/4B (4-14 ft bgs), FCC-5A/5B (5-13 ft bgs), FCC-8B (6-8 ft bgs), and FCC-9 (6-8 ft bgs).
Based on a review of the DEQ Risk Calculator which incorporated data from both properties did
not increase risk at the receiving Red Carpet Inn Brownfield Property. Therefore, DEQ
Brownfields approves up to 1,500 cubic yards of soil to be exported to the Red Carpet Inn
Brownfields Property.

All soil export must be conducted under a DEQ Brownfields approved Environmental
Management Plan (EMP). Soils should be field screened during excavation prior to export from
the property. If unanticipated impacts are identified during excavation, please refer to the EMP
for further actions and cease transfer until appropriate characterization can be completed In
addition, in accordance with the approved EMPs, annual Redevelopment Summary Reports will
be submitted to DEQ Brownfields. Details related to the disposition of this soil including but not
limited to, total volume, general description of field screening efforts, etc. should be included
with each Property’s Redevelopment Summary Report.

necessary permits, licenses, or certifications which may be required from other state or local
entities. If you have questions about this correspondence or require additional information, please

To whom it may concern,

I am B. Lemar Cullum, Director of Design and Construction for MOD CLT Property, LLC (the
Prospective Developer and property owner of the Red Carpet Inn Brownfields site). We have a need
for structural fill at the Red Carpet Inn site and understand that soils suitable for use as structural fill
are available for import from the Dynatech II Brownfields site. Accordingly, I authorize the transfer
of soils between the two projects, pending NCDEQ’s approval that the soils in question are
appropriately similar to those located at Red Carpet Inn Brownfields site and may be transferred
between the two sites.

Sincerely,

** - Note that the EPA has no consensus on reference dose or cancer slope factor values for lead, therefore it is not possible to calculate cancer risk or hazard quotient. Lead concentrations are compared to the EPA screening level of 400
mg/kg for residential soil.
