The RR Program seeks your input on a significantly revised document titled, RR-800, Addressing Vapor Intrusion at Remediation & Redevelopment Sites in Wisconsin. The revisions to RR-800 include: updates from ITRC’s and USPEA’s vapor guidance; additional details on required deliverables; expectations for outreach; clarification on preemptive mitigation; and a significantly expanded discussion on vapor mitigation (design options, performance verifications, long-term operation and maintenance, and continuing obligations).

The document can be reviewed at http://dnr.wi.gov/news/input/guidance.html and comments can be submitted through September 8, 2017 to the Vapor Intrusion Team Leader, Alyssa Sellwood at Alyssa.Sellwood@wisconsin.gov. In addition, the RR Program will host a question and answer session on Tuesday, August 29th.  Mark your calendars; more details to come.
