Environmental Impact Assessment

WIMR East Wedge Cyclotron and Expansion Project

University of Wisconsin – Madison

UW Project # 1485-2343

A public meeting to present the Draft Environmental Impact Assessment (DEIA) for the proposed WIMR East Wedge Cyclotron and Expansion Project construction project will be held virtually at 5:00 p.m. on Tuesday, September 16, 2025 via Microsoft Teams Meeting (link to meeting: WIRM East Wedge Public Meeting | Meeting-Join | Microsoft Teams or https://teams.microsoft.com/meet/2338847446665?p=ryWyptMxBLx5eDRkOX).

A description of the project and potential environmental impacts will be presented, and all persons will be afforded a reasonable opportunity to identify both orally and in writing any support, issues, or concerns they believe should be addressed during the EIA process for this proposed project. The EIA will be prepared in accordance with the Wisconsin Environmental Policy Act (WEPA), Wisconsin Statutes 1.11. Cornerstone Environmental Group, a Tetra Tech company, has been retained on behalf of The University of Wisconsin System Administration Capital Planning and Budget to prepare an EIA for the proposed East Wedge.

This project involves expanding the existing cyclotron facility at the University of Wisconsin–Madison by installing a new commercial cyclotron and constructing supporting space adjacent to the School of Medicine and Public Health (SMPH) biomedical research facilities at the Wisconsin Institutes for Medical Research (WIMR), located at 1111 Highland Avenue in Madison, WI. The new construction will take place on a site known as the “East Wedge,” situated between the WIMR I and WIMR II towers.  The project adds 57,363 GSF to the WIMR facility, which is currently 653,867 GSF. The project total cost is anticipated to be $62,000,000.

The purpose of the DEIA is to identify the potential impacts of the project on the physical, biological, social, and economic environments. The DEIA describing these potential impacts is being made available to the public and to appropriate federal, state, and local agencies for a 15-day minimum review period, which begins September 2, 2025, and concludes September 16, 2025. Copies of the document will be available for review at the Madison Central Library and UW-Madison Helen C. White Library, or available for download below.
