Subject: Brownfields Property Soil Transfer Approval
Dynatech Properties and AJACC Auto Brownfields Property Charlotte, Mecklenburg County Brownfields Project No. 25001-21-060, 25067-21-060 and 24054-20-060
Mr. Ellerbe and Mr. Glover,
The North Carolina Department of Environmental Quality (DEQ) Brownfields Program received and reviewed a request to export approximately 17,000 cubic yards of soil from Dynatech Brownfields Properties to AJACC Auto Brownfields Property. This request was submitted on
your behalf by Ms. Haley Martin of Hart & Hickman (H&H) in her email dated February 11. 2022,
titled 25001&25067- 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 17,000 cubic yards of soil from the Dynatech Brownfields Properties from the following sections FCC-2B, FCC-3A/B, FCC-4A/B, FCC-5A/B, FCC-8B, and FCC-9. Based on a review of the DEQ Risk Calculator which incorporated data from both properties did
not increase risk at the receiving AJACC Auto Brownfield Property. Therefore, DEQ Brownfields approves up to 17,000 cubic yards of soil to be exported to the AJACC Auto 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.

Please be advised that this approval does not waive any applicable requirement to obtain any 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 feel free to contact me by phone at 704-661-0330 or by email at Carolyn.minnich@ncdenr.gov.

Carolyn,
H&H understands that the AJACC Auto Brownfields property (BPN 24054‐20‐060) located off of Verbena Street in
Charlotte is planning import of up to 17,000 cubic yards of fill material as part of the proposed redevelopment. The PDs
for the Dynatech II and Dynatech III Brownfields properties (BPNs 25001‐21‐060 and 25067‐21‐060) are requesting
approval to transfer excess soil generated during mass grading activities in the areas of in situ soil characterization areas
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) to the AJACC Auto Brownfields property. The soil characterization areas
to be exported from the Dynatech Brownfields properties are outlined in green on the attached Figure. In accordance
with the DEQ‐approved Environmental Management Plan (EMP), excess soil in these soil characterization areas can be
transferred to another Brownfields property for use as fill material, with concurrence from DEQ Brownfields. It is of note
that shallow soils from evaluation areas FCC‐2 (0‐5 ft bgs), FCC‐3 (0‐4 ft bgs), and FCC‐4 (0‐4 ft bgs) will not be exported
from the Dynatech Brownfields properties without prior DEQ approval.
We have prepared the attached Soil Export Request Package which includes a tabular summary of the highest
concentrations detected at both the Dynatech II and III Brownfields properties and the AJACC Auto Brownfields
property, a figure depicting the location of the soil characterization areas at the Dynatech properties, and cumulative
worst‐case risk calculations. In summary, no organic compounds were detected in soil samples collected in the in situ
soil characterization areas FCC‐2B, FCC‐3A/3B, FCC‐4A/4B, FCC‐5A/5B, FCC‐8B, and FCC‐9 at concentrations above the
2
DEQ IHSB Protection of Groundwater or Residential PSRGs. In addition, detected concentrations of metals at the
Dynatech properties appear to be consistent with those detected at the AJACC Auto Brownfields property.
H&H calculated the cumulative risks using the highest concentration of any compound at either Brownfields property to
model hypothetical “worst‐case” exposure scenarios under a residential, non‐residential, construction worker, and
trespasser scenario. As expected, risk calculations indicate that direct exposure soil pathway for a resident, non‐
residential worker, construction worker, and trespasser do not exceed the threshold criteria for carcinogenic or non‐
carcinogenic risks.
The export package also includes email confirmation from the PD of AJACC Auto, Greystar Development East, LLC,
indicating they are willing to accept the proposed export material from the Dynatech properties. Based on the detected
compound concentrations below the DEQ IHSB Residential PSRGs and the results of the worst‐case risk calculations, the
PD requests DEQ approval to transport material from in situ soil characterization areas FCC‐2B, FCC‐3A/3B, FCC‐4A/4B,
FCC‐5A/5B, FCC‐8B, and FCC‐9 to the AJACC Auto Brownfields property.
As you may know, grading construction work is ongoing. We appreciate your reviewing this data to assist in keeping the
construction schedule on track. In the meantime, please let us know if you have any questions or concerns.
Thank you,
Haley

Good Morning Chris,
Thanks for taking time to discuss the opportunity for a Brownfields-to-Brownfields soil transfer
opportunity for your development at the AJACC Auto (24054-20-060) Brownfields property. The
prospective developer (PD) for the DynaTech II, III, and IV (25001-21-060, 25067-21-060, and 25068-
21-060) Brownfields properties located near the corner of Toomey Avenue and W. Tremont Avenue
in Charlotte, is seeking to get rid of approximately 22,000 cubic yards (CY) of soils from upcoming
excavation areas.
Per the NCDEQ-approved Environmental Management Plan (Link) for the DynaTech properties,
several areas (FCC-2B, FCC-3, FCC-4, FCC-5, FCC-8B, and FCC-9) have been identified as favorable for
transfer to another Brownfields property provided written approval by NCDEQ Brownfields of a soil
transfer request. We are estimating between 10,000 – 15,000 CY of soils will be generated from
these areas, but we will have more precise numbers soon as we progress through the approval
process.
Please reply to this email to confirm your interest in receiving these materials provided they meet
your requirements and a transfer request is approved by the NCDEQ Brownfields Program.
Best,
