The Remediation and Redevelopment (RR) Program is now seeking input on the publication Vapor Intrusion Guidance (RR-800).
This publication provides guidance for persons who investigate, remediate and mitigate contaminated sites under Wisconsin Statute (Wis. Stat.) ch. 292 and Wisconsin Administrative (Wis. Admin.) Code chs. NR 700 – 799. The guidance applies to sites where contaminated vapor has, or has the potential, to migrate to any current or future buildings.
The document can be found at the RR Program’s Public Notices & Guidance webpage under the “Program Guidance” tab. Comments may be submitted through July 27, 2025, to Jennifer Borski at Jennifer.Borski@wisconsin.gov or DNRRRGuidance@wisconsin.gov.
