Chemicals that have seen industrial use for decades are now beginning to be better understood by scientists and others concerned with their potential impacts to human health and the environment. Per- and polyfluoroalkyl compounds (PFASs) are a class of emerging contaminants known to impact environmental media, such as groundwater, soil, sediment and surface water.
Additional information about PFASs can be found on the EPA’s web page, the ITRC’s collection of fact sheets and through the Agency for Toxic Substances and Disease Registry (ATSDR).
When discharged to the environment, PFAS compounds meet the definitions of hazardous substance and/or environmental pollution under Wis. Stat. § 292.01. Discharges of PFASs to the environment are subject to regulation under Wis. Stat. § 292 and the requirements for immediate notification, investigation, and remediation in Wis. Admin. Code chs. NR 700 through 754.

The Wisconsin DNR’s Remediation and Redevelopment Program has updated the numerical soil standards in its spreadsheet of residual contaminant levels (RCLs). The RCLs were determined using the recently-updated U.S. EPA regional screening level (RSL) web-calculator.
A summary of the changes to the direct-contact RCLs can be found in the new document, titled “RR Program’s Soil RCL Spreadsheet Update,” publication number DNR-RR-052f.
For more information and to access the RCL spreadsheet (macro and non-macro versions), visit the Resources for Environmental Professionals webpage and click on the “Soil RCLs” tab.
The Remediation and Redevelopment Program puts to good use the skills and knowledge of its customers by working together in a collaborative manner through a number of External Advisory Groups (EAG). In fact, it’s one of the core values of the agency. And with funding from the US EPA’s 128(a) grant, the Brownfields and Outreach Section assists these groups with messaging and keeping customers and the public informed.
Now in its 20th year of advising the agency is the Brownfields Study Group (BSG). The study group is one of the oldest EAGs, created in 1998 at the direction of the Governor and State Legislature to evaluate Wisconsin’s brownfields initiatives and recommend improvements, as well as propose additional incentives for brownfields redevelopment. The BSG continues to drive important brownfields policy changes in Wisconsin and among its successes can count the creation of the Site Assessment Grant Program, which awarded more than $18 million to more than 200 communities before it was transferred to a different agency. The group was also instrumental in developing the One Cleanup Program Agreement with Region 5 EPA, the most comprehensive agreement of its kind, which helps expedite cleanups of properties across the state.

On October 4, 2017, please join the RR Program for a teleconference discussion of the RCL spreadsheet and a substitute method of calculating alternative non-industrial direct-contact residual contaminant levels (RCLs) for select carcinogenic polycyclic aromatic hydrocarbons (cPAHs).
Waste management specialist Paul Grittner and hydrogeologist David Swimm, both with the RR Program, will discuss the modified soil RCL spreadsheet which can be used to attain compliance when the applicable cPAH direct contact RCLs in NR 720 is not practicable. The spreadsheet changes how non-industrial direct contact RCLs for seven cPAHs are assessed. The spreadsheet evaluates cPAH compounds on a cumulative basis only, rather than on an individual compound basis and a cumulative basis.
This approach is allowed under NR 722, but the DNR’s pre-approval is required prior to implementation. Paul and David’s presentation will focus on the process recommended for assessing PAH data using the modified soil RCL spreadsheet, as well as the DNR pre-approval process.
The teleconference will take place at noon on Oct. 4. No pre-registration is required. Call 1-855-947-8255 and use passcode 6612 745#. This presentation will be recorded and available the following day on the RR Program’s Training Library.
The Remediation and Redevelopment (RR) Program seeks your input on a new guidance document titled Calculating Soil RCLs for PAHs Wis. Admin Code § NR 722.11 (1) (RR-079).
This guidance document introduces the modified residual contaminant level (RCL) spreadsheet that allows for an alternative method of calculating non-industrial direct contact RCLs for seven carcinogenic polycyclic aromatic hydrocarbons (cPAHs). The modifications are based on a reassessment of the risk posed by cPAHs by the Wisconsin Department of Health Services.
The modified spreadsheet assesses these cPAHs exclusively on cumulative risk and does not assess their individual compound-specific risk. Use of this spreadsheet complies with the requirements of Wis. Admin. § NR 722.11 for developing alternate standards when meeting the RCLs in Wis. Admin. § NR 720 is not practicable.
The comment period will be open through May 31, 2017. This document can be reviewed on the Department’s public input web page, and comments can be submitted to Paul Grittner.
The RR Program recently finalized four new guidance documents regarding the management of contaminated soil and other waste materials excavated at sites or facilities in locations other than a licensed landfill.
This guidance is the culmination of several years of discussion between the RR Program and external stakeholders, including more than 20 individuals who served on the program’s Contaminated Materials Management Advisory Group and other interested parties who also participated in meetings. The group was formed in May 2015 and met more than a dozen times to provide input on issues related to materials management. The RR Program thanks those who participated for sharing their time and perspective.
These new guidance documents include:
- RR-060, Management of Contaminated Soil and Other Solid Wastes Wis. Admin. Code §§ NR 718.12 and NR 718.15, provides a general overview of the exemptions available under NR 718 for managing excavated material, a description of when these exemptions may apply, and a summary of the application process and requirements.
- RR-071, NR 718.12 Sample Results Notification, provides a cover page that may be used when submitting laboratory reports to the DNR to satisfy the requirements of NR 718.12(1)(e)(4).
- RR-072, Recommended Format for Exemption Request Wis. Admin Code NR 718.12 or NR 718.15, provides a consistent format to demonstrate that the proposed management of solid waste material, as a remedial or interim action, qualifies for a NR 718.12 or NR 718.15 exemption and to request written approval of the exemption from the DNR.
- RR-073, Request for Exemption from Location Criteria of NR 718.12(1)(c) for Managing Soil as an Immediate Action, provides a format to request that the DNR allow management of soil, as an immediate action, in an area that will not comply with the location criteria listed in NR 718.12(1)(c).
