Interstate Technology Regulatory Council Comprehensive Vapor Intrusion Mitigation Training June 2 and 14

Posted on by Jodie Thistle

The Interstate Technology Regulatory Council (ITRC) will offer online, comprehensive vapor intrusion training based on recent, technical guidance from the national group.

The upcoming live webinars will cover the purpose and use of the Dec. 2020 comprehensive web-based series of technical resources for Vapor Intrusion Mitigation.

Staff from the DNR’s Remediation and Redevelopment Program participated in the development of both the technical resources and training.

The training consists of a series of eight modules on the sections listed below and will be presented over two, two-hour sessions:

  • Thursday, June 2, 2022 (noon to 2 p.m. CST)
  • Tuesday, June 14, 2022 (noon to 2 p.m. CST)

Environmental professionals are encouraged to register and participate.

A link to the ITRC’s web-based document is posted on the DNR’s Vapor Intrusion Resources for Environmental Professionals website under the “Guidance and Forms” tab. This document includes an interactive directory that includes 10 fact sheets, 16 technology information sheets, and four checklists, covering the following topics specific to vapor intrusion mitigation:

  • Conceptual site model
  • Public outreach
  • Rapid response and ventilation (for acute risk)
  • Active mitigation
  • Passive mitigation
  • Remediation and institutional controls
  • Design considerations
  • Post installation considerations
  • Operation, maintenance and monitoring/exit strategy
  • Emerging technology

While the documents are designed to assist state regulators, they also serve to raise awareness with environmental consultants and other industry professionals.

The online sessions will be repeated on Nov. 3 and 15, 2022. If watching the training through on-demand video playback is preferred, you can find the same vapor intrusion trainings here.

Site-specific questions regarding vapor intrusion in Wisconsin should be directed to the assigned DNR Project Manager. General questions can be directed to the contacts listed on the DNR’s Vapor Intrusion Resources for Environmental Professionals website.
