Public Input Opportunity – Publication RR-0115, Guidance: Contaminated Sediment Fact Sheet

The Remediation and Redevelopment (RR) Program is now seeking input on the publication RR-0115, Guidance: Contaminated Sediment Fact Sheet

The fact sheet is a brief outline of the typical approaches that are used to navigate through Wisconsin Statutes (Wis. Stat.) ch. 292 and Wisconsin Administrative Code (Wis. Admin. Code) chs. NR 700 to 799 with respect to the investigation and remediation of contaminated sediment.

The document can be found at the RR Program’s Public Notices & Guidance web page under the “Program Guidance” tab.

Comments may be submitted through July 1, 2021 to Carrie Webb at CarrieA.Webb@wisconsin.gov or to DNRRRGuidance@wisconsin.gov.

Now Available: Publication RR-649, Guidance for Documenting the Investigation of Human-made Preferential Pathways Including Utility Corridors

Following a public comment period and consideration of the comments received, the publication RR-649, Guidance for Documenting the Investigation of Human-made Preferential Pathways Including Utility Corridors, is now posted and available online.

RR-649, formerly titled Guidance for Investigating Utilities, focused on investigating the migration of contamination in media along the exterior of utility corridors within the surrounding utility bedding. Current research indicates that contamination and vapors may migrate within utilities as well as other preferential pathways and the updated version of RR-649 reflects this new understanding. For additional information, please see the July 2020 Issues & Trends webinar, Vapor Intrusion: New Preferential Pathways, in the Remediation and Redevelopment Program’s training library.

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

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.

Wisconsin Adjusts PFAS Default Reporting List for Regulatory Sampling and Lab Certification from 36 to 33 PFAS Compounds

After careful consideration, effective March 1, 2021, the Wisconsin Department of Natural Resources (DNR) no longer expects regulated entities, unless otherwise directed by DNR, to sample for or laboratories to report three of the 36 PFAS compounds on the default PFAS list. Site-specific circumstances may influence whether the DNR approves a deviation for sampling for those 33 PFAS compounds.

NR 700 Reporting Due January 30

Semi-annual reporting for the period of July 1, 2020 to December 31, 2020 is due by January 30, 2021. Semi-annual reporting is required of responsible parties (RPs) for all open sites, including those sites the DNR formerly classified as “conditionally closed” in the BRRTS online database. Consultants may submit these reports on behalf of RPs.
