The Menominee Indian Tribe of Wisconsin has sued the U.S. Environmental Protection Agency (“EPA”) and Army Corps of Engineers (“Corps”) over the proposed Aquila Resources Back Forty Mine, arguing that EPA and Corps have failed to take responsibility for reviewing wetland permits for the project. The lawsuit was expected since the Tribe filed a notice of intent to sue in November 2017.  

Aquila Resources has proposed an open pit mine, deemed the “Back Forty Mine,” to extract gold, zinc, and other metals. The mine would be located in Michigan’s Upper Peninsula and adjacent to the Menominee River, which forms the boundary between Wisconsin and Michigan. The river flows into Lake Michigan. The Michigan Department of Environmental Quality (“MDEQ”) is the permitting authority and has issued three of the four permits required for the project, including a Nonferrous Metallic Mineral Mining Permit, a Michigan Air Use Permit to Install, and a National Pollutant Discharge Elimination System (NPDES) permit. A permit for wetland impacts is still required and is under review by MDEQ. Given the location of the wetlands near a commercially navigable interstate waterway, normally the Corps and EPA would have wetland permitting authority and permitting would also trigger an obligation for the federal agencies to consult with the Tribe under the National Historic Preservation Act. However, MDEQ is one of two state agencies which has been delegated additional permitting authority under the Clean Water Act by EPA for permitting of wetlands under federal jurisdiction, and MDEQ is not required to consult with the Tribe.  

The Tribe is alleging that the federal government has deprived it of treaty rights that are supposed to protect its cultural and historical sites. The Tribe’s sacred place of origin is within its 1836 treaty territory at the mouth of the Menominee River and there are numerous sacred sites and burial mounds located along the river, including in the area of the proposed mine. The Tribe is also concerned about the potential impact of acid mine drainage from the mine on the water and fishery resources in the area and Great Lakes ecosystem. According to the Tribe, it has been trying to meet and consult with the Corps and EPA for months, but the agencies have not responded in a meaningful way. The Tribe has asked the court to order EPA and the Corps to take over the wetland permitting process.
