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

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.

Best Practices For Finding RR Program Publications and Guidance Documents

The DNR’s Remediation and Redevelopment (RR) Program will be moving all publications and guidance documents to a new server location in March 2022. This will result in a new URL to access these files. The migration will also affect the search results when looking for publications using the magnifying glass search tool found at the top of the DNR website through approximately June 2022.

During this transitional period, the DNR recommends using the search tools found on the publications and forms webpage when looking for an RR publication.

Using the Keyword Search Tool, users can locate a publication by searching for the publication number (beginning with “RR-”) or a word or phrase from the document title or description. A dropdown menu is also available to search by topic.

The Full-Text Search Tool searches documents’ content; you can type a general term or short phrase to find all RR guidance documents containing those words.

Please direct any questions regarding the use of the RR Program’s publications, forms and guidance search web tools to Peggy Frain at margaret.frain@wisconsin.gov.

Reminder – Correct Fee Amounts For NR 700 Submittals

RR Program Makes Website Changes To Enhance Customer Service

The Remediation and Redevelopment (RR) Program has reconfigured its main landing pages and added redevelopment resources to the RR Sites Map to better serve our customers.

New And Improved Landing Pages

The RR Program oversees the investigation and cleanup of environmental contamination throughout the state and provides technical guidance and assistance to responsible parties and environmental professionals.

Equally, the RR Program helps local governments, prospective purchasers, lenders, developers and property owners understand and navigate the redevelopment and revitalization of brownfields, which are properties that are contaminated or suspected to be contaminated.

RR Program has reorganized its website using three separate topic-specific landing pages:

The new Environmental Contamination and Cleanup landing page is geared towards environmental professionals and includes direct links to numerous technical topics and links to the guidance and forms index, the RR Sites Map and the Bureau for Remediation and Redevelopment Tracking System (BRRTS). Environmental professionals should bookmark this new page designed specifically to provide links to the most-sought technical resources.

The Brownfields landing page serves as a toolbox for local governments, prospective purchasers, lenders, developers and property owners. It provides information on the basics of cleaning up and redeveloping a contaminated site and information regarding liability, financial resources, how to schedule Green Team meetings with the Wisconsin Department of Natural Resources (DNR) and success stories of brownfields redevelopment projects throughout the state.

The Spills landing page provides instruction on reporting hazardous substance spills and discharges in Wisconsin.

Further improvements include prominent links to the RR Submittal Portal and the RR Report newsfeed on each landing page. Users will also now find quick access to public input opportunities and a link to a new external advisory groups page.

Saved or bookmarked pages will continue to work seamlessly; these upgrades only affect the RR Program’s landing pages.

RR Sites Map

RR Sites Map is the RR Program’s GIS mapping application that provides information about remediation and redevelopment activities in Wisconsin. Recently, redevelopment resources were added to help users evaluate sites in relation to socioeconomic data, including links to the U.S. Environmental Protection Agency (EPA) Superfund Redevelopment Mapper, the U.S. EPA Environmental Justice Screening and Mapping Tool and the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR) Social Vulnerability Index. In addition, layers from the CDC/ATSDR Social Vulnerability Index are now available on the map (in the map and data tasks tab, select the layer catalog, then choose Non-DNR Data and Social/Cultural/Economic Information).

The RR Program welcomes your feedback on these improvements. Send your thoughts and suggestions to Jodie Peotter at jodie.peotter@wisconsin.gov.

Wisconsin Vapor Quick Look-Up Table Updated

Updated publication RR-0136, Guidance: Wisconsin Vapor Quick Look-Up Table is now posted and available online.

The document can be found on the Vapor Intrusion for Environmental Professionals webpage. Additional documents and guidance from the Remediation and Redevelopment Program may be found using the search tools available on the publications and forms webpage.

The document lists select volatile organic compounds frequently encountered at remediation sites; it is updated periodically based on updates to inhalation toxicity data, generally semi-annually when the U.S. EPA updates its table (last updated in November 2021). Consultants should compare vapor data for open sites to the updated table for potential additional actions and should routinely reference the webpage for the most recent version.

The February 2022 version includes the removal of infrequently used chemicals:

  •  Methyl tert-Butyl Ether (MTBE),
  • 1,2,4-Trimethylbenzene (TMB),
  • 1,3,5-TMB, and
  • Xylene (m, o and p separately)

Consultants should compare vapor data for chemicals not available on Wisconsin’s Vapor Quick Look-Up Table directly to the U.S. EPA’s Vapor Intrusion Screening Level Calculator; instructions are included on Wisconsin’s Vapor Quick Look-Up Table.

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 webpage.
