    City of Waukesha Proposed Great Lakes Diversion

    ENVIRONMENTAL IMPACT STATEMENT

    WISCONSIN DEPARTMENT OF NATURAL RESOURCES

  • Environmental Impact Statement i

    To the Reader The City of Waukesha lies within a county that straddles the Great Lakes surface water divide and is therefore eligible to seek an exception from the prohibition of diversions under the Great Lakes—St. Lawrence River Basin Sustainable Water Resources Agreement (Agreement) and Great Lakes—St. Lawrence River Basin Water Resources Compact (Compact). The Agreement is a good faith agreement between the Great Lake States and Provinces to manage water quantity in the Great Lakes Basin. The Agreement is implemented in the United States through the Compact—a legally binding contract among the eight Great Lakes States. The Applicant seeks to obtain a Lake Michigan water supply as a solution to its current water supply problems that include elevated levels of radium in the drinking water supply above the drinking water standard. This document is an Environmental Impact Statement (EIS), prepared by the Wisconsin Department of Natural Resources (DNR) in compliance with Wisconsin Administrative Code (Wis. Adm. Code) Chapter NR 150, and Wisconsin Statute (Wis. Stat.) s. 1.11. The purpose of an EIS is to inform decision-makers and the public of the anticipated effects on the quality of the human environment of a proposed action or project and alternatives to the proposed action or project. The EIS is an informational tool—it is not a decision document. The EIS process began when the public was invited to provide comments on the scope of the EIS analysis between February 5, 2010 and August 13, 2011. In 2011, three public scoping meetings were held on July 26, 27 and 28 in Pewaukee, Wauwatosa and Sturtevant, respectively. The DNR received 102 public scoping comments. In October 2013, the City of Waukesha (Applicant) submitted a revised Application for a Lake Michigan Diversion with Return Flow (Application) to the Wisconsin Department of Natural Resources (DNR) and an Environmental Impact Report (EIR) to describe the proposal and potential environmental consequences. By 2015, the DNR prepared a Technical Review, draft EIS and preliminary final EIS. The Technical Review outlined the DNR’s findings related to the Agreement, Compact and Wisconsin’s Compact implementing statutes (a requirement of Article 201 of the Agreement, section 4.9 of the Compact, and Wis. Stat. s.281.346(4)(e)1.f.). The DNR invited the public to comment on the draft EIS between June 25 to August 28, 2015. The DNR received 3,634 written comments from individuals and groups. Additionally, comments were received at three public hearings on August 17 and 18, 2015 in Waukesha, Milwaukee and Racine. Of the 404 people who registered at the hearings, 128 provided oral testimony. The preliminary final EIS included the DNR’s response to public comments. On January 7, 2016, the DNR forwarded the preliminary final EIS, Technical Review and Application to the Great Lakes States, and Quebec and Ontario through the Great Lakes – St. Lawrence River Water Resources Regional Body (Regional Body) and Great Lakes – St. Lawrence River Water Resources Compact Council for review and decision as required by the Agreement and Compact. The Regional Body is the governing body of the Agreement and includes the Great Lakes premiers and governors. The Compact Council is the governing body of the Compact and includes the Great Lakes governors. Throughout this process, Great Lakes Tribes and First Nations were informed of the proposal and provided opportunities to comment. The Regional Body approved the proposed diversion with conditions on June 21, 2016, as described in this EIS.

  • Environmental Impact Statement ii

    In 2017, the department received additional information in a supplemental EIR from the Applicant for their Lake Michigan water supply and Root River return flow. This EIS explains the Applicant’s proposal to use water from Lake Michigan (in order to meet its water supply needs) and return wastewater to the Lake Michigan basin as required by the Agreement and Compact. It analyzes potential impacts of alternative water supply and return flow options, including the current proposal, and includes other analyses not presented in the draft or preliminary final EIS documents. The Compact Council and Regional Body has conditionally approved the diversion. Before any specific permits or approvals are issued, the DNR is issuing this EIS and will be issuing a WEPA compliance determination. The Applicant will need to acquire all permits and approvals for the diversion from the State of Wisconsin before the DNR can approve the diversion. The DNR maintains a website with information related to the Applicant’s diversion application, including the public participation process, communications with the Applicant, and other supporting materials.
