Brownfields Project No. 24007-20-032
Dear Mr. Bevers,
The North Carolina Department of Environmental Quality Brownfields Program (DEQ
Brownfields) received and reviewed the Vapor Intrusion Mitigation Design (VIMDesign), dated
September 30, 2022, and DEQ Brownfields has found this VIM Design to be in compliance with the
Brownfields Vapor Intrusion Mitigation System Design Submittal Requirements dated July 2021.
Consistent with standard brownfields vapor intrusion provisions which will be included in the
brownfields agreement for this project, an essential component of public health protection for this
design is the professional engineer's seal of these documents that the proposed design will be
effective at mitigating the potential for vapor intrusion at the property and protecting public health.
Furthermore, the safe occupancy of the building will be evaluated upon system effectiveness,
sub -slab soil gas sampling, and indoor air sampling as required by Section 4.0 of the VIMDesign.
In addition, DEQ Brownfields reserves the authority to require confirmation of efficacy in the
future.
Please be advised that this design 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 feel free to contact me at 919-707-8238, or via e-mail
at Holly. Samahakncdenr.gov.
