The North Carolina Department of Environmental Quality (DEQ) has drafted new and revised guidance documents for the assessment and mitigation of vapor intrusion (VI) at properties undergoing reuse and redevelopment (Draft Guidance). Spearheaded by the Brownfields Redevelopment Section of DEQ’s Division of Waste Management, the proposed new guidance was developed in February and presented to stakeholders for review and comment on March 10, 2023. At that time, DEQ solicited comments for 30 days on the new and revised guidance, and comments are now being reviewed by DEQ.
