Metallic Minerals Permitting

Presently, 10 permits have been issued to operators by the Missouri Department of Natural Resources under the Metallic Minerals Waste Management Act.

Metallic Mineral Waste Management permit applications consist of financial assurance information and detailed waste management area closure and inspection-maintenance plans, which must be reviewed and updated every five years. The plans establish and explain the technical steps proposed to accomplish and maintain closure after mining and waste disposal is completed. Issues addressed in the plans include:

  • The design and construction of waste control structures and tailings dams.
  • The characterization of waste products.
  • The methods for control and protection of surface water.
  • The methods for protection of groundwater and aquifers.
  • The geology and seismicity of the area.
  • The reclamation of the waste disposal areas.
  • Designated land uses.

During the ongoing permit application review, the program coordinates with the other Department of Natural Resources’ programs and divisions involved with the metallic minerals waste management areas. These include the Division of Environmental Quality’s Air Pollution Control Program, Water Pollution Control Branch, Waste Management Program, Public Drinking Water Branch, Environmental Remediation Program and Missouri Geological Survey. This coordination process allows other programs to review and comment on the technical aspects of the plans so all environmental issues may be incorporated into the permit.

The following table is a summary of the current permits issued for the management and ultimate reclamation of metallic mineral waste. All are for the primary management of lead waste tailings except for Permit MM-007, which is issued for the management of iron ore waste tailings. Additionally, a map of these sites can be accessed by the Industrial and Metallic Mineral Mine Sites map viewer.

Metallic Minerals Inspection

Inspections are performed semiannually on the 10 metallic minerals waste management permit areas within Missouri. During the course of these inspections, all aspects of each company’s permits are evaluated. The main focus of these inspections is to assess the company's compliance with environmental laws administered by the Missouri Department of Natural Resources. The program is entrusted as the coordinating agency within the department for each active metallic mineral producer currently operating in Missouri.

Reclamation does not begin at these sites until mineral production is stopped, and mine closure begins. Three of the metallic mineral mine sites are in closure at the present time. Teck American Incorporated, Magmont Mine ceased production in 1995 and began reclamation of the surface effects of almost 30 years of lead mining, processing, and waste disposal. On Dec. 27, 2017, Director Carol Comer released 318 acres of the Magmont Mine, 53 acres remain permitted. Two of The Doe Run Company’s slag storage areas at the former primary lead smelters, Glover and Herculaneum, are also going through closure and being capped with soil material. Clean up and repurposing of these sites is in progress.

Metallic Minerals Enforcement

Enforcement under this law is significantly different from enforcement under either the coal or industrial minerals units of the program. If it should become necessary to issue a citation to any of the metal producers, the authority to do so rests solely with the director of the Department of Natural Resources. Enforcement is only authorized by law after attempts to eliminate the violation through conference, conciliation and persuasion have been exercised and exhausted.
