Previous seminars and workshops

May 10, 2018: Brownfields Conference for Local Government

The DNR's RR Program hosted a day-long conference on May 10, 2018, for local government officials on brownfields redevelopment. This conference discussed the steps and procedures to get communities from a brownfield cleanup to a redevelopment groundbreaking.

The presentations are available in the RR Program training library.

April 4, 2018: Issues & Trends
The DNR's Vapor Intrusion Guidance Summary

Alyssa Sellwood, a hydrogeologist with the Remediation and Redevelopment Program, led a conference call on the recently updated guidance, Addressing Vapor Intrusion at Remediation and Redevelopment Sites in Wisconsin (RR-800), revised in January 2018. During the conference call, Sellwood walked participants through key updates to RR-800 and discussed several topics related to vapor mitigation in greater detail, including mitigation in new construction and the importance of performance verification.

The presentation is available in the RR Program training library.

Oct. 4, 2017: Issues & Trends
An Alternative for Determining Soil RCLs for PAHs

Paul Grittner and David Swimm, RR Program policy staff, led a discussion and Q & A session of the RCL spreadsheet and a substitute method of calculating alternative nonindustrial direct-contact residual contaminant levels (RCLs) for select carcinogenic polycyclic aromatic hydrocarbons (cPAHs). A modified approach is allowed under NR 722, Wis. Adm. Code, but the DNR’s pre-approval is required prior to implementation. Paul and David’s presentation focused on the process recommended for assessing PAH data using the modified soil RCL spreadsheet, as well as the DNR pre-approval process.

The presentation is available in the RR Program training library.

Sept. 6, 2017: Issues & Trends
Vapor Intrusion: Action Criteria, Mitigation, and Long-term Monitoring

Alyssa Sellwood, the Remediation and Redevelopment Program’s vapor intrusion and dry-cleaning team leader, will present the Issues & Trends conference call in September. Alyssa will discuss vapor intrusion sampling, including a discussion of action triggers, mitigation and long-term monitoring.


The presentation is available in the RR Program training library.

August 9, 2017: Issues & Trends
A Preview and Discussion of the DNR’s New Vapor Intrusion Guidance

Alyssa Sellwood, a hydrogeologist and vapor intrusion team leader with the Remediation and Redevelopment Program, will give an overview of the RR Program’s new guidance on vapor intrusion – RR 800 – addressing vapor intrusion at remediation and redevelopment sites in Wisconsin. We originally published the guidance in 2010, but revisions have been necessary as knowledge and understanding of vapor intrusion has grown. The guidance is being readied for public comment and includes such updates as commissioning and inspecting vapor mitigation systems, mitigating vapor risk in new construction, and evaluating and addressing potential vapor risk in large commercial and industrial buildings.

The presentation is available in the RR Program training library.

April 12 and April 20, 2017: DNR Consultants' Day 2017 Conferences

The DNR's Remediation and Redevelopment Program would like to thank the nearly 300 guests and staff who attended Consultants’ Day events in Stevens Point and Pewaukee. Guests heard from a number of program staff on subjects such as NR 700.11, Wis. Adm. Code, required submittals, site investigation completeness, PAH reassessment, case closure reconsideration, modifications to continuing obligations, vapor intrusion outreach and more.

The presentation is available in the RR Program training library.

Feb. 8, 2017: Issues & Trends
Environmental Issues for Demolition – Asbestos, Lead, PCBs and More

Ed Lynch, Hazardous Waste Section Chief, will provide an overview of requirements for managing hazardous materials as part of renovation and demolition projects. The DNR's Asbestos Coordinator Mark Davis and Mark Chamberlain, Air Management Specialist, will provide an overview on NR 447, Wis. Adm. Code, "Control of Asbestos Emissions." When facilities are undergoing renovation or demolition and asbestos-containing materials could be disturbed, the requirements of the EPA's national emissions standards for hazardous air pollutants (NESHAPS) apply. The presentation will discuss the asbestos inspection, notification and disposal requirements for demolition/renovations projects involving commercial/industrial facilities.

The presentation is available in the RR Program training library.

Jan. 11, 2017: Issues & Trends
PCB Remediation in Wisconsin: How PCB Sample Results are Used, Cleanup Options and Steps

Engineer Gary Edelstein and Policy and Technical Resources Section Chief Judy Fassbender provide an overview of PCBs in Wisconsin, including a discussion of the “One Cleanup Program” agreement between DNR and EPA. When PCB contamination is discovered at a cleanup site, Federal Toxic Substances and Control Act (TSCA) requirements can apply. The approach to cleanup may differ from that of sites governed only by Wisconsin’s NR 700, Wis. Adm. Code, process, but DNR has an agreement with EPA to lead the cleanup at many TSCA regulated sites. The presentation outlines what responsible parties need to do when PCBs are discovered and how to work with the DNR and the EPA to conduct the cleanup in the most efficient and cost-effective way.

The presentation is available in the RR Program training library.

Dec. 7, 2016: Issues & Trends
Hazardous Waste Determinations and Management Options at Remediation Sites in Wisconsin

Gary Edelstein, an engineer with the Remediation and Redevelopment Program, presents an overview of the RR Program’s “Guidance for Hazardous Waste Remediation,” with concentration on hazardous waste and contained out determinations, contaminated media management options and the DNR review procedures. The program provides this training in part to respond to recent inquiries regarding guidance implementation and agency review procedures, including who has responsibility for making certain decisions. It also provides an introduction for those who aren’t familiar and a refresher for those who are.

The presentation is available in the RR Program training library.
