This guidance provides an optional approach for responsible parties and their environmental consultants to use when soil is characterized and excavated as part of a response action (i.e., cleanup action), and the soil does not need to be managed at a licensed solid waste facility or through a site-specific exemption in Wis. Admin. Code chs. NR 718 or the NR 500 rule series. The document provides responsible parties clarity on what types of substances – if identified in soil – could generally be managed as “exempt soil” in accordance with state law without the department’s pre-approval or tracking.
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.
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 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.
