DNR Awards Brownfields Grant To Village Of Clinton

Posted on by Mick

The Wisconsin Department of Natural Resources (DNR) announced the site where a former gas station that later served as a small engine repair shop in the Village of Clinton is on its way to being cleaned up with help from a grant from the department.

The financial award comes from the DNR’s Wisconsin Assessment Monies (WAM) program, which provides contractor services worth up to $35,000 for eligible sites. The DNR awarded the grant to the Village of Clinton for the now-vacant property that is known to have some degree of contamination, though just how much contamination is unknown.

Issues & Trends Webinar on April 20, 2021: Vapor Intrusion – Acute Risk Associated with TCE

Posted on by Mick

The Remediation and Redevelopment (RR) Program reminds you that the next webinar in the Issues & Trends series will take place next week, April 20, 2021, from noon to 1:00 p.m.

The scheduled presentation is: Vapor Intrusion – Acute Risk Associated with TCE.

The presentation is a discussion of the acute risk associated with trichloroethylene (TCE) in vapors. Presenters and guests will provide background on TCE and its prevalence in Wisconsin, along with a discussion of short-term, health-related concerns. Speakers will also explain the need to prioritize vapor investigations when TCE is a contaminant of concern, DNR’s authority under NR 708 and the DNR’s partnerships with DHS and local health departments.

Reminder Letter Sent To Responsible Parties To Prioritize Vapor Intrusion Evaluations At Sites With TCE

Posted on by Mick

The Wisconsin Department of Natural Resources (DNR) Remediation and Redevelopment (RR) Program is sending a reminder letter regarding vapor intrusion to parties responsible for cleanup at open remediation sites in Wisconsin. A copy of the letter will also be sent to the responsible party’s (RP) environmental consultant.

The letter is a reminder to RPs and consultants that the potential for short-term (i.e., acute) health risks associated with trichloroethylene (TCE) in indoor air are serious enough that it should be one of the first things evaluated as part of a site investigation. This is especially true on sites where contamination may impact sensitive populations and should be routinely reassessed throughout a project’s life to ensure protectiveness.

DNR Adopts the Department of Health Services’ Recommended Hazard Index (HI) Approach

DNR Adopts the Department of Health Services’ Recommended Hazard Index (HI) Approach for Evaluating Human Health Risk of Certain PFAS due to Ingestion of Drinking Water

On Nov. 6, 2020, the Wisconsin Department of Health Services (DHS) provided the Wisconsin Department of Natural Resources (DNR) recommended groundwater standards for 16 PFAS substances (known as “Cycle 11”). Shortly thereafter, DHS provided recommendations to DNR for utilizing a hazard index approach to assess the cumulative risk of these PFAS, including PFOA and PFOS from Cycle 10. The hazard index risk assessment approach is used to assess the cumulative risks of compounds with similar health effects that are typically found as mixtures in environmental samples. This approach has been employed by DHS to evaluate certain classes of pesticides and volatile organic compounds as well as by the United States Environmental Protection Agency (EPA) to evaluate the risk posed by non-carcinogenic chemicals found at Superfund sites.
