Grand River Draft EIS Notice of Intent/NEPA Scoping Meeting

SUMMARY: Pursuant to the requirements of the National Environmental Policy Act (NEPA) of 1969, as implemented by the Council on Environmental Quality Regulations, the U.S. Army Corps of Engineers (USACE) Detroit District, announces its intent to conduct public scoping and solicit public comments to gather information to prepare a draft Environmental Impact Statement (EIS) on behalf of the Great Lakes Fishery Commission (GLFC) related to the proposed Grand River Habitat Restoration and Invasive Species Control Project in Grand Rapids, Michigan.

If implemented, the project is expected to adversely impact existing healthy mussel population, which includes the federally-listed endangered scaleshell and snuffbox mussels as well as a number of state listed mussel species. DATES: Comments for consideration in the development of the scope of the NEPA draft EIS are due no later than May 15, 2019. Comments may also be made at the public scoping meeting as noted below. All comments and materials received, including names and addresses, will become part of the administrative record and may be released to the public.
