Public Input Opportunity for DNR Publication Guidance on Addressing Contaminated Sediment Sites in Wisconsin (RR-0124)

The Remediation and Redevelopment (RR) Program is now seeking input on the publication Guidance on Addressing Contaminated Sediment Sites in Wisconsin (RR-0124).

The purpose of this guidance is to outline approaches for investigating and remediating hazardous substances discharges that impact sediment to comply with the requirements in Wisconsin Statutes (Wis. Stat.) ch. 292 and the applicable provisions of Wisconsin Administrative (Wis. Admin.) Code chs. NR 700-799. This guidance explains the steps recommended for assessment of contaminated sediment, evaluation of remedial options and the selection, design, implementation and monitoring of remedial actions. This guidance will clarify closure requirements at sites with contaminated sediments, including continuing obligations, long term stewardship and financial assurance.

The document can be found at the RR Program’s Public Notices & Guidance webpage under the “Program Guidance” tab. Comments may be submitted through Jan. 11, 2023 to Carrie Webb at or

The Remediation and Redevelopment (RR) Program updated its Case Closure Request Form 4400-202 to clarify under which circumstances Wisconsin Administrative (Wis. Admin.) Code ch. NR 749 database fees should be submitted and to provide updated information regarding electronic submittals.

The updates only affect page 1; no other changes were made to the form. Anyone submitting a new case closure request must use the updated form per Wis. Admin. Code § NR 726.09(1). If you previously submitted a case closure request with the correct fee, you do not need to provide an updated page 1 with a resubmittal. Please contact the regional team supervisor if you have questions regarding your case closure request.

Issues & Trends Webinar on Nov. 16, 2022: Passive Air Sampling for Vapor Intrusion

The Remediation and Redevelopment (RR) Program shares that the next webinar in the Issues & Trends series will take place on Nov. 16, 2022, from noon-1 p.m.

The scheduled presentation is Passive Air Sampling for Vapor Intrusion.

The webinar will spotlight changes in recommendations for vapor intrusion sampling (e.g., longer duration passive sampling in lieu of evacuated canister sampling for vapor intrusion investigations).

Colder temperatures and the indoor heating season are the preferred conditions for conducting vapor intrusion sampling. In anticipation of increased sampling during the winter months, DNR staff will provide the latest recommendations for sampling methods for soil gas, sanitary sewer and sewer cleanouts, indoor air and sub-slab vapor.

Additional topics addressed during the webinar will include a review of the health risk concerns and randomly timed 8-hr or 24-hr samples, different passive samplers, considerations when selecting appropriate samples and how to evaluate the data.

Environmental consultants working on sites with volatile organic compounds (VOCs), particularly chlorinated solvent sites, are encouraged to attend.

A Zoom web conferencing registration link may be found on the RR Program’s Conferences and Training webpage.

Recordings of previous Issues & Trends webinars may be found in the RR Program’s Training Library.

    • Type of grant being applied for: multipurpose, assessment, cleanup or revolving loan fund
    • The name, title and mailing address of the person to whom the letter should be addressed (i.e., the representative of the entity applying for the grant)
    • A general description of the community concerns about the property related to brownfields, socioeconomic challenges and redevelopment needs
  • For assessment grants, include the following information:
    • The property address, a brief history of ownership, a brief history of site-specific land use and why the property is suspected of being contaminated; include DNR Bureau for Remediation and Redevelopment Tracking System (BRRTS) identification number(s), if applicable

    • The property address, a brief history of ownership, a brief history of site-specific land uses and why the property is known to be contaminated; include BRRTS identification number(s), if applicable
    • A statement of whether the applicant and/or landowner intends to enroll the property in the voluntary party liability exemption program
    • The approximate timeframe to complete site investigation, begin cleanup at the property, submit reports required under Wis. Admin. Code chs. NR 700-799 and estimated time for DNR staff review
  • For petroleum contamination cleanup or assessment grants, include the following information:
    • The current property owner, occupant and the immediate past-owner of the property
    • The date and method by which the current owner acquired the property (e.g., purchase, tax foreclosure)
    • Whether the applicant, the current owner, or immediate past-owner dispensed or disposed of petroleum on the property
    • Whether the applicant, the current owner, or immediate past-owner took reasonable steps to contain any known contamination
    • Whether there are any state or federal environmental judgments or orders, or third-party suits or claims against the current or immediate past-owner, and if the current or immediate past-owner has the financial means to comply
    • Reasons why any of the above information may not be available

Grants awarded by the EPA provide resources that can be used for various brownfield activities, with an opportunity to transform contaminated sites into community assets that attract jobs and achieve broader economic development outcomes.
