Michigan’s Part 632

Michigan’s nonferrous metallic mining regulations (Part 632) guide the construction, operation, closure, and post-closure of mining operations. The law also guides monitoring, reclamation, and remediation of nonferrous metallic mineral mines in the state of Michigan. Before Part 632 passed in 2004, Michigan’s then-governor formed a workgroup to discuss increased ecological protection if mining took place. The group comprised of the Yellow Dog Watershed Preserve, environmental groups, industry, the Michigan DNR, Michigan DEQ, and Eagle Mine (formerly Rio Tinto). Today, Part 632 is considered one of the most stringent mining laws in the United States. Several states in the Midwest have studied Michigan’s law when updating their own rules. The link below will take you to an overview of Part 632. The mining law is a great document to review if you have interest concerning mining in your community.
