Community involvement and public participation are an essential part of EGLE’s mission, vision, and values.
SARA Title III establishes requirements regarding emergency planning and "Community Right-to-Know" reporting on hazardous and toxic chemicals for federal, state, local, and tribal governments, as well as regulated facilities.
Tracking and understanding all of the state and federal environmental regulations affecting local governments can be a daunting task. We provide simple explanations and helpful resources for the regulatory programs that apply to local government operations and access to funding resources that promote sustainability on this page.

An interactive map displaying contaminated sites throughout Michigan regulated under Parts 213, 201, and 211.
The Michigan Department of Environment, Great Lakes, and Energy’s (EGLE) Water Well Viewer (WWV), is an interactive mapping system that displays water wells along with other information, such as wellhead protection areas, underground storage tanks, and sites of environmental contamination. Water well locations have been identified by address matching, the use of global positioning systems (GPS), and by legal descriptions.
This system allows water well drilling and pump installation contractors to submit water well records.

Regulated by Part 632: Nonferrous Metallic Mining, of the Michigan Natural Resources Environmental Protection Act (NREPA) PA 451, as amended, 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.
Eagle Mine is an active underground nickel and copper mine operated by Eagle Mine LLC, a subsidiary of Lundin Mining Inc, located in Michigamme Township, northern Marquette County.
Eagle ore deposits are high-grade magmatic sulfide deposits containing primarily nickel and copper mineralization and minor amounts of cobalt, platinum, palladium, and gold. Surface facilities cover an area of about 150 acres and include temporary storage of ore, development rock, and aggregate; a cement rock fill plant; mine ventilation and egress; access decline; water storage, water treatment plant and treated water discharge system; and other ancillary facilities.

Eagle Mine ore is transported by haul trucks to Humboldt Mill, located in Humboldt Township, Marquette County, for processing.
The Humboldt Mill facility was originally constructed in 1954 to concentrate low grade iron ore from the Humboldt Mine. The Humboldt Mine was developed in two stages over its life, beginning with underground ore removal, followed by open pit extraction. In the early 1980’s, the mill was converted to gold ore processing and operated until 1989 when the Ropes Mine, located about 10 miles from the mill, was closed. After reconstruction of the mill, Eagle Mine began crushing and processing ore to nickel and copper concentrates. As during the processing of Ropes ore, residual tailings are placed for permanent subaqueous disposal in the Humboldt Tailings Disposal Facility (the previously mined pit area).

Part 632 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. EGLE's Geologic Resources Management Division (GRMD) implements Part 632. The nonferrous metallic mining industry is also regulated by other environmental statutes and divisions within EGLE such as the Air Quality Division and Water Resources Division.
A Part 632 mining permit is not effective until all required permits have been obtained, and the permittee establishes financial assurance pursuant to the applicable statutes and rules. Various permits that may be required under NREPA are organized by the corresponding EGLE division below.
