The address for the Remediation and Redevelopment program is changing. As of Oct. 10, 2026 the new address will be 4822 Madison Yards Way, PO Box 7921, Madison, WI 53707-7921.
The address change is the result of the Wisconsin DNR’s move from its downtown office building to its new location at the Hill Farms state office building located on the west side of Madison. Please note the change will not affect staff member phone numbers.
Semi-annual reporting for the period of Jan. 1, 2026 to June 30, 2026, is due by July 31, 2026. 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 Remediation and Redevelopment Tracking System. Consultants may submit these reports on behalf of RPs.
The DNR will send an email with a unique Report Identification (ID) number to contacts of sites listed in the database during the first week of July 2026. If you do not receive an email by July 7, 2026, you can request a Report ID number by submitting the Report ID Request Form.
The Report ID number uniquely identifies the activity you can report, the reporting period and verifies the person using the Report ID is authorized to submit the report. If you have any questions, please contact Tim Zeichert at Timothy.Zeichert@wisconsin.gov or 608-219-2240.
State law requires semi-annual reports from people who meet the definition of a responsible party (Wis. Admin. Code s. NR 700.11(1)(a)). Property owners, such as local governments that have an exemption under Wis. Stats. §§ 292.11(9)(e) or 292.23, and lenders that have an exemption under Wis. Stats. § 292.21 for specific properties are not required to submit a semi-annual report for those exempt properties under state law.
Sites formerly classified by the DNR as “conditionally closed” are open sites that have not been granted case closure and, by definition, have remaining action(s) needed (e.g., properly abandoning monitoring wells or investigative waste needing to be removed).
Semi-annual reporting for sites formerly classified as “conditionally closed” should indicate what actions are being taken to complete the remaining actions.
The next reporting period starts July 1, 2026.
Change in Reporting Timelines
The semi-annual reporting timeframes are changing. To accommodate the change, the next site progress report submitted will cover an eight-month period, with the reporting period beginning on July 1, 2026 and ending on Feb. 28, 2027 (Wis. Admin. Code 700.11(1)(a)). During the first week of March 2027, you can expect to receive an email with a unique Report Identification (ID) number.
Following the reporting period ending in February 2027, semi-annual reporting will continue to be required at 6-month intervals and follow the schedule below.
| Reporting periods | Report due date |
| March 1 to Aug. 31 | Sept. 30 |
| Sept. 1 to Feb. 28 | March 31 |
The Kansas State University’s Technical Assistance to Brownfields (TAB) group is hosting two webinars to share information to help build a team with the knowledge needed to successfully move through a brownfields project. Building Your Brownfields Team is a two-part series scheduled for June 30, 2026 and July 1, 2026.
Part one of the series will explore building the support needed for the project from stakeholders and technical experts. The second session will focus on the process of cleaning up the site to enable redevelopment. For more information and to register visit the TAB webpage.
In Wisconsin, the Remediation & Redevelopment Program is available to help you apply what you learn to move forward with brownfield redevelopment in your community. The first step is often a request by a local government for a “Green Team” meeting to discuss resources available to support your brownfields team. For more information, see Green Team Assistance.
Visit the DNR’s webpage to learn more about opportunities for brownfield redevelopment in Wisconsin.
The Wisconsin Department of Natural Resources (DNR)’s Remediation and Redevelopment Program will be collecting soil samples from locations across Wisconsin as part of a study to characterize background concentrations of per- and polyfluoroalkyl substances (PFAS) and polycyclic aromatic hydrocarbons (PAHs) in surface soil.
PFAS are a large group of human-made chemicals that have been used in industry and consumer products worldwide since the 1950s. PAHs are chemical compounds with both natural and anthropogenic sources. Both PFAS and PAHs can impact human health.
The samples will be collected from surface soil in approximately 150 locations from undisturbed areas that are unlikely to have been impacted by discharges of PAHs or PFAS. Samples will be collected from areas that represent both rural and urban land uses. Analysis of the samples will help characterize the ambient concentration of these contaminants found in soil from atmospheric deposition. The results may be used to calculate statewide background threshold values for PFAS and PAH contaminants in soil. Sampling will occur on DNR-owned land in coordination with the property managers.
Sampling will take place in 2026 from May through July. Results will be shared in a final report anticipated in 2027. Contact Trevor Nobile with questions about the soil background study at Trevor.Nobile@wisconsin.gov or 414-852-5310.
The U.S. Environmental Protection Agency (EPA) Regional Screening Level (RSL) Calculator and the Vapor Intrusion Screening Level (VISL) Calculator webpages are once again available on the U.S. EPA’s webpage.
The Wisconsin Department of Natural Resources (DNR) uses these calculators to establish soil residual contaminant levels (RCLs) that may be used by responsible parties to meet cleanup standards in Wis. Admin. Code ch. NR 720 and to establish indoor air Vapor Action Levels (VALs) and Vapor Risk Screening Levels (VSRLs), consistent with relevant definitions set forth in Wis. Admin. Code ch. NR 700.
Please contact Erin Endsley with any questions about soil RCLs or Jennifer Borski with any questions about vapor levels.
Mark your calendars to participate in upcoming training hosted by the Wisconsin Department of Natural Resources (DNR)’s Remediation and Redevelopment program. The trainings are hosted as part of the RR Program’s Issues & Trends series which provide updates and information from the RR Program on issues related to environmental contamination and cleanup.
The trainings are offered virtually and registration is required. Anyone involved in the investigation, remediation and mitigation of contaminated sites under Wisconsin Statute (Wis. Stat.) ch. 292 and Wisconsin Administrative (Wis. Admin.) Code chs. NR 700 – 799 is encouraged to attend.
Schedule and Session Details
Vapor Intrusion Topics
March 23, 2026, 11:30 a.m. to 1 p.m.
Register to attend by Zoom.
This session will offer an overview of information available in the Vapor Intrusion Guidance (RR-800) published in January 2026. The publication is a comprehensive resource when working on sites with contaminated vapor that has migrated or has the potential to migrate to current or future buildings. The presenters will highlight how the guidance can help you identify the conditions that may indicate the need for more investigation and the responses and actions that follow discovery of vapor intrusion. The session will also offer information about web-based forms now available to help document building evaluations that can guide you through assessment of vapor related concerns at a building and log inspections of vapor mitigation systems after installation and commissioning.
Using Monitored Natural Attenuation in Cleanup of Contamination
June 24, 2026, 11:30 a.m. to 1 p.m.
Register to attend by Zoom.
The session will highlight the newly published Monitored Natural Attenuation Guidance (RR-0156) and considerations when selecting and using monitoring natural attenuation (MNA) as a remedial option for cleaning up contamination. As part of the session, presenters will highlight the responsibilities of consultants and others and highlight available tools to support informed decision-making that considers the regulatory framework, site investigation components, and lines of evidence. The session will also review the importance of monitoring to verify the effectiveness of the use of MNA.
Deep Dive into Vapor Intrusion: Application of RR-800
July 16, 2026, 11:30 a.m. to 1 p.m.
Register to attend by Zoom.
Presenters will dive deeper into the steps to address a site with vapor intrusion or the potential for vapor intrusion, with a focus on the publication Vapor Intrusion Guidance (RR-800). The presenters will share scenarios to show how to investigate the vapor intrusion pathway and the considerations and actions needed after vapor intrusion is identified.
Conduit Vapor Intrusion: Application of RR-649 and RR-800
Sept. 17, 2026, 11:30 a.m. to 1 p.m.
Register to attend by Zoom.
This session will provide an update on vapor intrusion through conduits. Presenters will go over updates to the publication Guidance for Documenting the Investigation of Human-made Preferential Pathways Including Utility Corridors (RR-649) and relevant portions of the publication Vapor Intrusion Guidance (RR-800). This session will also offer an opportunity for you to ask questions specific to preferential pathways.
More information about the topics is available on our webpage at dnr.wi.gov; search “Vapor Intrusion” or “Natural Attenuation.”

Semi-annual reporting for the period of July 1 to Dec. 31, 2025, is due by Jan. 30, 2026. 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 Bureau for Remediation and Redevelopment Tracking System (BRRTS) online database. Consultants may submit these reports on behalf of RPs.
The DNR will send an email with a unique Report Identification (ID) number to contacts of sites listed in the database during the first week of January 2026. If you do not receive an email by Jan. 6, 2026, you can request a Report ID number by submitting the Report ID Request Form.
The Report ID number uniquely identifies the activity you can report, the reporting period and verifies the person using the Report ID is authorized to submit the report. If you have any questions, please contact Tim Zeichert at Timothy.Zeichert@wisconsin.gov or 608-219-2240.
Wisconsin Administrative Code § NR 700.11(1)(a) requires semi-annual reports from people who meet the definition of a responsible party in NR 700. Local governments that have an exemption under Wisconsin Statute (Wis. Stat.) §§ 292.11(9)(e) or 292.23 and lenders that have an exemption under Wis. Stat. § 292.21 are not required to submit a semi-annual report for those exempt sites.
Sites formerly classified by the DNR as “conditionally closed” are open sites that have not been granted case closure and, by definition, have remaining action(s) needed (e.g., properly abandoning monitoring wells or investigative waste needing to be removed).
Semi-annual reporting for sites formerly classified as “conditionally closed” should indicate the current actions to complete the remaining actions.
The next reporting period is from Jan. 1, 2026, to June 30, 2026.
The DNR is excited to announce that the RR Program Submittal Portal (Submittal Portal) has switched to MyWisconsin ID.
You can now use your MyWisconsin ID to log in to Submittal Portal. You may need to update your bookmark to this system. You will be prompted to verify your identity with the multi-factor authentication (MFA) option you selected during the enrollment process.
If you have not created a MyWisconsin ID, details and a step-by step guide are available on the Department of Administration’s MyWisconsin ID Self Registration webpage.
Tips For Successful Registration
Some state systems will transition to using MyWisconsin ID sooner than others. In the meantime, you may need a WAMS ID for some systems and a MyWisconsin ID for others.
