Subject: Vapor Intrusion Mitigation Plan Addendum Philcron Automotive II 2161 Hawkins Street Charlotte, Mecklenburg County
Brownfields Project Number 23060-19-060 Dear Ms. McKenzie: The North Carolina Department of Environmental Quality’s Brownfields Redevelopment
Section (DEQ Brownfields) received and reviewed the Vapor Intrusion Mitigation Plan
Addendum (Addendum) dated May 23, 2023, for the above referenced Brownfields Property. The Addendum proposes the use of the TerraVentTM sub-slab vapor collection product and revising the layout of vent risers to accommodate the revised building design. DEQ Brownfields finds the requested modification to satisfy elements of the Land Use Restrictions of the pending
Brownfields Agreement for design of a vapor mitigation system, and as such, this letter
constitutes DEQ Brownfields approval of the modification request.
As will be expressed 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. In addition, DEQ Brownfields reserves the
authority to require confirmation of efficacy in the future.
Be advised that this review from DEQ Brownfields does not waive any applicable requirement to obtain any necessary permits, licenses or certifications for the above listed activities nor does it waive any requirement to comply with applicable law for such activities.
