Reminder Letter Sent to Responsible Parties to Evaluate for Emerging Contaminants During Site Investigations

The Remediation and Redevelopment (RR) Program is sending 3,038 letters to parties responsible for cleanup at open remediation sites in Wisconsin.

The letter is a reminder to those responsible parties (RPs) to consider per- and poly-fluoroalkyl substances (PFAS) or other suspected emerging contaminants (e.g. 1,4 – Dioxane) during the site investigation scoping phase of their remediation efforts, per NR 716.07 and NR 716.09. A site investigation may be considered incomplete if the RP does not consider and address all hazardous substances or environmental pollution at a known site or facility subject to ch. 292, Wis. Stats., including emerging contaminants like PFAS.  Failure to do so could result in the need for additional assessment work or field work and potential closure delays.

Public meetings for input on proposed emergency rule RR-11-17E

The Remediation and Redevelopment (RR) Program will host two public meetings to seek input on the development of revisions to Wis. Admin. Code chs. NR 700–799, Environmental Protection – Investigation and Remediation of Environmental Contamination.

These meetings will focus on gathering input regarding proposed emergency rules (board order RR-11-17E). The proposed emergency rules implement statutory financial assurance requirements under 2015 Wis. Act 204 that apply to certain types of sites with contaminated sediment.

  • The first meeting will be held via Skype from 10:30 a.m. to noon on Tuesday, June 23, 2020.
  • The second meeting will be held via Skype from 2:00 p.m. to 3:30 p.m. on Monday, July 6, 2020.

If you plan to attend the meeting, please RSVP to Molly Schmidt and specify whether you will attend the first meeting, second meeting, or both meetings.

The Skype links and meeting materials for each meeting are available at: https://dnr.wi.gov/topic/Brownfields/RuleChanges.html, along with further information regarding this rulemaking effort.

Public Input Opportunity: PECFA Usual and Customary Cost Schedule #27

The Remediation and Redevelopment (RR) Program seeks your input on the Usual and Customary (U&C) Task Reference Guide #27 (Publication RR 0113-E) and U&C Cost Schedule #27 (Publication RR 0113a-E). Both documents are available for review on the Wisconsin DNR’s proposed program guidance web page.

Comments on these documents are due by January 6, 2020, and may be submitted to DNRRRGuidance@wisconsin.gov. Please use the subject line: RR-19-0113-D.

Document updates include a number of items related to the investigation and mitigation of vapor intrusion, such as the reimbursement of initial installation and vapor sampling, separating out costs associated with equipment needed to install vapor sampling points, and a new subtask for subsequent vapor sampling events after initial installation and sampling.

Site Investigation “Toolkit” Now Available Online

The Remediation and Redevelopment Program recently developed a web page called the “SI Toolkit” to provide environmental consultants and others with a framework for site investigation (SI) work plans and reports.

The new web page makes documents pertaining to site investigation (guidance, checklists, forms and rules) easy to find in one place. New SI-related guidance and factsheets will be added to this web page as they are developed.

Contact Jane Lemcke if you have questions or suggestions regarding the new SI Toolkit.
