Issues And Trends Webinar: Investigation Of Vapor Intrusion Along The Utility Conduit Pathway

Issues and Trends Banner

The Remediation and Redevelopment (RR) Program’s next webinar in the Issues & Trends series will take place on Nov. 7, 2024.

Understanding vapor intrusion pathways at contaminated sites is an important aspect of protecting human health when investigating discharges to the environment that include volatile compounds. The steps to investigate the utility conduit pathway of vapor intrusion, which may include sanitary and storm sewers, sumps and building plumbing, is the topic of an upcoming webinar presented by the DNR.

Investigation of Vapor Intrusion along the Utility Conduit Pathway
Nov. 7, 2024
10 – 11:30 a.m.
Register to attend by Zoom
.

The webinar will cover important information about vapor intrusion along the conduit pathway. Presenters will summarize the results of a multi-year effort to collect several hundred samples within conduits at approximately 70 sites in Wisconsin. Attendees will learn some of the basic concepts of how contaminant vapors enter and travel through utility conduits, eventually reaching indoor air. The webinar will review options to sample for vapor intrusion including a discussion of the DNR’s approach to conduit sampling during state-funded investigations.

The webinar is part of the RR Program’s Issues & Trends series. This series offers webinars that provide program and rulemaking updates and information on issues related to environmental contamination and cleanup. Past “Issues & Trends” are available to view by visiting our RR Presentations & Training Library.

Redevelopment Of Brownfield Properties: Learning Sessions For Local Governments: Assistance Available For Reuse Of Underused And Abandoned Properties

The Wisconsin Department of Natural Resources (DNR) will host learning sessions for local governments on redevelopment of underused and abandoned properties, otherwise known as brownfields, on Nov. 12 in Whitewater, Nov. 15 in Dodgeville and Nov. 20 in Shawano. The sessions are free to attend and the same content will be covered in each location.

A brownfield is a property where real or perceived contamination complicates expansion, redevelopment or reuse. Brownfields may be found in many locations throughout the state and vary in size, age and past use.

The in-person sessions will share information about resources available to support local governments in redevelopment of properties into community assets. Participants will learn how to identify brownfield sites in their community and understand the liability considerations and due diligence recommended when acquiring brownfield properties. Highlights of the sessions include an overview of funding and other assistance available to support redevelopment efforts.

“I didn’t know what a brownfield was until the day before the event,” states Lisa Lien, clerk for the village of Clayton said after attending an event hosted by the DNR in Spooner in April 2024. “I learned a ton during the seminar and now have a great understanding of brownfield redevelopment.”

The learning sessions will also offer an opportunity for local governments to connect one-on-one with representatives from the DNR and Wisconsin Economic Development Corporation (WEDC) and ask questions about brownfield properties and redevelopment.

Public Input Opportunity On Two Publications – Guidance: Contaminated Soil Quick Reference Table (RR-106) and Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151)

The Remediation and Redevelopment (RR) Program is now seeking input on two publications. 

  • Guidance: Contaminated Soil Quick Reference Table (RR-106) 
  • Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151) 

The purpose of the publications is to provide resources for externals to look up soil residual contaminant levels, or RCLs, that are developed using standard equations in the U.S. Environmental Protection Agency (EPA) Regional Screening Level (RSL) Calculator. RCLs are commonly used at remediation sites but are not required. The responsible party (RP) has the option to develop and propose a site-specific soil standard. The Contaminated Soil Quick Reference Table contains contaminants commonly encountered at remediation sites. The Soil RCL Spreadsheet “does the math” to make it easier for the RP and their consultant, but using it is optional.  

The DNR updated the publications in response to the U.S. EPA’s May 2024 update to its RSLs. Screening levels for 18 contaminants changed since the last update to the DNR’s publications in 2018. Ten common contaminants were added to the Soil RCL Spreadsheet and it also incorporates a cumulative risk calculator for carcinogenic polycyclic aromatic hydrocarbons (cPAHs).  

The documents can be found at the RR Program’s Public Notices webpage. Comments may be submitted through Oct. 2, 2024, to Erin Endsley at Erin.Endsley@wisconsin.gov or DNRRRGuidance@wisconsin.gov.

Current NR 700 Rulemaking Efforts Discontinued

The Wisconsin Department of Natural Resources (DNR) today announced it will discontinue current administrative rulemaking efforts related to the investigation and cleanup of hazardous substance discharges to the environment.

Wisconsin Statutes (Wis. Stat.) Ch. 292 directs certain parties to clean up contaminated sites in Wisconsin; Wisconsin Administrative (Wis. Admin.) Code chs. NR 700-799 provide the specific steps and standards for conducting cleanup activities.

In January 2024, two scope statements were approved for rulemaking by the Wisconsin Natural Resources Board. The scope statements were related to continuing obligations (Board Order RR-14-23) and soil cleanup (Board Order RR-15-23). Rulemaking efforts are intended to provide clarification to existing statutes that are helpful to our external partners and customers as they work to investigate and clean up contamination in our state.

The DNR formed the NR 700 Rule Advisory Committee (RAC) to advise DNR staff during development of these proposed rules. Through meetings with the RAC, DNR recognized the need for and importance of taking additional time to conceptualize how best to revise the rules to meet the shared objectives of the DNR and external partners and customers.

The DNR will discontinue efforts on both scope statements and will allow the authority to work on rule revisions to expire. All meetings of the NR 700 Rule Advisory Committee (RAC) are cancelled.

The DNR would like to recognize and thank the RAC and many other members of the public who have provided us with valuable input on both draft rules. Our collaborative work is not lost. The DNR will consider the input we have received, will continue to work with the RR EAG, and will reintroduce scope statements in the future to restart work on the rules.

The DNR will continue to apply its authority under existing statutes and rules to serve our customers as they are accustomed and ensure protection of public health and the environment.

Sign up to receive future chs. NR 700-799 rulemaking updates and meeting announcements.

VMS Active Notification Information Now Available

New information focused on use of active notifications including using telemetry systems when monitoring an active vapor mitigation system (VMS) is now available on the vapor intrusion resources for environmental professionals webpage.

Monitoring of an active VMS is important to ensure that the system continues to work as designed. Active notifications (continuous monitoring) may include audible alarms, visual indicators and telemetry.

The webpage is a resource for environmental professionals and provides considerations for selecting the type of systems to install including land use, the type of health risk and the contaminant of concern.

View a recorded presentation for more information about active notifications and telemetry systems; Issues & Trends: Vapor Intrusion Updates 2023 (wisconsin.gov). Information specific to active notification is on slides 12 through 21.
