Subject: Vapor Mitigation Design Compliance Review
ECU Life Sciences and Biotechnology Center
Greenville, Pitt County
Brownfields Project No. 22003-18-074
Dear Mr. Jordan:
The North Carolina Department of Environmental Quality Brownfields Program (DEQ
Brownfields) received and reviewed the Vapor Intrusion Mitigation System (VIMS) Design
Submittal dated December 16, 2019. DEQ Brownfields has found this VIMS Design Submittal to
be in compliance with the DEQ Brownfields VIMS Design Submittal, New Construction Minimum
Requirements Checklist dated March 2018.
Consistent with standard brownfields vapor intrusion provisions which will be included in the
future 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, any final occupancy approval from DEQ Brownfields will ultimately be
based on the differential pressure measurements and/or analytical results of samples collected as
outlined in Section 4.0 of the VIMS Design Submittal. Note that Terracon has committed to
submitting a separate work plan for the sub -membrane testing to DEQ Brownfields for review. In
addition, DEQ Brownfields' reserves the authority to require confirmation of efficacy in the future.
