Alyssa Sellwood, the Remediation and Redevelopment Program’s vapor intrusion and dry-cleaning team leader, will present our Issues & Trends conference call in September. Alyssa will discuss vapor intrusion sampling, including a discussion of action triggers, mitigation and long-term monitoring.
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).
Alyssa Sellwood, a Hydrogeologist with the Remediation and Redevelopment Program and the leader of the dry cleaning and vapor intrusion teams, will present the next Issues & Trends training event on Wednesday, August 9, at noon. No pre-registration is required.
Sellwood’s presentation will be an overview of forthcoming additions and modifications to the RR Program’s existing guidance on vapor intrusion – RR 800 – Addressing Vapor Intrusion at Remediation and Redevelopment Sites in Wisconsin. We originally published the guidance in 2010, but revisions are necessary as knowledge and understanding of vapor intrusion has grown. The guidance is being readied for public comment and includes such updates as commissioning and inspecting vapor mitigation systems, mitigating vapor risk in new construction, and evaluating and addressing potential vapor risk in large commercial and industrial buildings.
The RR Program recently added four, new online tools to our vapor intrusion (VI) prevention web page to assist environmental professionals as they prepare VI assessments or plan for outreach on a site impacted by vapor intrusion.
Vapor Intrusion 101 video uses a hand drawn animation technique to introduce the concept of vapor intrusion. It is intended for use in conjunction with factsheets and personal communication when talking with a property owner who is unfamiliar with vapor intrusion.
RR-067: Vapor Intrusion Investigation – Information Sheet for Neighbors can be given to an off-site property owner when access is needed to investigate vapor intrusion on their property. This factsheet provides an introduction to environmental investigations, identifies the parties involved, and clarifies who the property owner can contact with questions.
The fourth new tool is on the same web page, under the “screening levels” tab:
