Both State and Federal permits are needed before construction in the river can begin.
Federal Permits:
Due to the presence of federally endangered snuffbox mussels in the Grand River, the project must comply with the Endangered Species Act and receive an Incidental Take Statement from the U.S. Fish & Wildlife Service (USFWS).
Due to the $4.1 million Regional Conservation Partnership Program funding agreement for habitat restoration through the U.S. Department of Agriculture Natural Resources Conservation Service (NRCS) an Environmental Assessment and Watershed Project Plan, effectively called the Plan-EA, must be written and approved by the NRCS to release the federal dollars. The NRCS will review the Plan-EA and will need to issue a finding of no significant impact (FONSI) to comply with the National Environmental Policy Act (NEPA) & the National Historic Preservation act (NHPA).
State Permits:
Permits needed from the State of Michigan are requested through the Joint Permit Application process through the Michigan Department of Energy, Great Lakes, and Environment (EGLE). The project will require the following Natural Resources and Environmental Protection Act (NREPA)  permits:
Part 301 of NREPA (Inland Lakes & Streams)
Part 303 of NREPA (Wetlands Permits)
Part 31 of NREPA (Floodplain Permit)
