Now Available – Two Publications: Guidance: Contaminated Soil Quick Reference Table (RR-106) And Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151)

Posted on by Coreen Fallat

Following a public comment period two publications are now posted and available online at the RR Program’s Contaminated Soil and Sediment  webpage: 

  • Guidance: Contaminated Soil Quick Reference Table (RR-106) 
  • Guidance: Soil Residual Contaminant Level (RCL) Spreadsheet (RR-0151) 

The purpose of the publications is to provide resources for externals to look up soil residual contaminant levels, or RCLs, that are developed using standard equations in the U.S. Environmental Protection Agency (EPA) Regional Screening Level (RSL) Calculator. 

The DNR updated the publications in response to the U.S. EPA’s May 2024 update to its RSLs. Screening levels for 18 contaminants changed since the last update to the DNR’s publications in 2018. Ten common contaminants were added to the Soil RCL Spreadsheet and it also incorporates a cumulative risk calculator for carcinogenic polycyclic aromatic hydrocarbons (cPAHs).

Questions on the publications may be submitted to Erin Endsley at Erin.Endsley@wisconsin.gov.

Additional documents and guidance from the Remediation and Redevelopment Program may be found using the search tools available on the publications and forms webpage.

The purpose of this guidance is to provide information to lenders and representatives about environmental liability exemptions available for sites with hazardous substance discharges to the environment.

Guidance: Post-Closure Modifications (RR-982)
The purpose of this guidance is to aid in the preparation and review of post-closure modification (PCM) submittals to the DNR. Information about the types of PCMs, the process, fees and types of responses available from the DNR is provided. This guidance is for use by property owners, responsible parties, environmental consultants and DNR staff. It is based on authority provided under Wisconsin Statutes (Wis. Stat.) § 292.12(6) and Wisconsin Administrative Code (Wis. Admin. Code) ch. NR 727.

Additional documents and guidance from the Remediation and Redevelopment (RR) Program may be found using the search tools available on the RR Document Search and Resource Portal.

Questions regarding RR-507 and RR-508 may be submitted to Molly Schmidt at MollyE.Schmidt@wisconsin.gov. Questions regarding RR-982 may be submitted to Jodie Thistle at Jodie.Thistle@wisconsin.gov.

Updates To Remediation And Redevelopment Program Guidance And Publications Search Tool

Posted on by Christine Sieger

The Department of Natural Resources (DNR) Remediation And Redevelopment (RR) Program Guidance And Publication Search Tool is currently undergoing maintenance that will result in a new look and web address, https://widnr.widencollective.com/portals/n3gjtfty/RRDocumentSearchPortal.

Starting June 30, 2023, the former web address will no longer be accessible and will result in a ‘page not found’ error. During the transition, both links will be active. Please update your bookmarks as soon as possible.

The update to the search tool includes a visual interface featuring publications, templates and forms as searchable collections. Multiple documents can be selected and downloaded at once and documents can be viewed in the web browser. Traditional search tools (i.e., general search and by subject/keyword) are available in the upper left-hand corner of each collection.

Links to other RR Program webpages, publications and documents should be unaffected. Contact DNRRRWebRequests@wisconsin.gov if you experience any issues.
