Service Seeks Public Input on Draft Environmental Assessment for Proposed Habitat Restoration on Wisconsin WMD’s

We are proposing to use genetically modified glyphosate tolerant (GMGT) corn and soybeans for the purpose of habitat restoration at Leopold and St. Croix Wetland Management Districts in Wisconsin. In accordance with the National Environmental Protection Act (NEPA), this proposed use requires the development of an environmental assessment (EA). This EA evaluates the impact of the proposed action, maps out other potential alternatives, and helps us select the best course of action. We are seeking public comments on the draft environmental assessment from August 15 through September 13, 2016. You may submit comments in person, as well as by email to or by mail to: St. Croix Wetland Management District Attn: GMGT Comments 1764 95th Street New Richmond, WI 54017
