NON-FERROUS METALLIC MINING

Regulated by Part 632: Nonferrous Metallic Mining, nonferrous minerals are important economic minerals such as copper, nickel, zinc, gold, and silver. Some of these metals are very important globally for manufacturing, including production of green technologies such as electric vehicles and emission control catalysts. Part 632: Nonferrous Metallic Mining provides a sound regulatory framework for construction, operation, and reclamation of mining operations required for the safe and environmentally sustainable extraction of these metallic minerals. The Department of Environment, Great Lakes, and Energy (EGLE) Oil, Gas, and Minerals Division (OGMD) implements Part 632.  The nonferrous metallic mining industry is also regulated by other environmental statutes and divisions within the EGLE such as Air Quality Division and Water Resources Division.
