Dynamic Auto Works II and Foundry
Charlotte, Mecklenburg County Brownfields Project Nos 26093-22-060 & 17021-13-060 Dear Mr. Liles,
The North Carolina Department of Environmental Quality Brownfields Redevelopment Section (DEQ
Brownfields) received and reviewed a request to export approximately 51,000 cubic yards of soil for the planned redeveloped at the above referenced Brownfields Properties. This request was submitted on your behalf in a Soil Export Request letter report dated December 8, 2023prepared by ONE Environmental Group of the Carolinas, PLLC.

Based on our review of the data, the DEQ Brownfield agrees that these soils may be exported as outlined in the table below. Other Beneficial Fill and Land Clearing & Inert Debris Landfill (LCID) options may be available; however, DEQ requires that the receiving facility be identified and discussed prior to export. The receiving facility should have metals concentrations which are consistent with those from the
Brownfields Properties.

DEQ Brownfields understands the redevelopment will be done jointly under one DEQ-approved Environmental Management Plan (EMP) under the development name “The Foundry”. All soil export must be conducted under an approved EMP. Soils should be field screened during excavation prior to export from the property. If unaanticipated 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 Dynamic Auto II EMP, an annual Redevelopment Summary Report 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 the Redevelopment Summary Report.
Please be advised that this compliance review from DEQ Brownfields 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 any questions, please contact me at (704) 661-10330, or via e-mail at [e-mail].
