Provisions will be made for back-up equipment in the event of the breakdown of critical operating equipment.
The design and operation specifications for mining waste site facilities include contingency measures, which may include emergency power supplies, redundant equipment, or temporary holding facilities, to deal with emergency conditions.
Any mining waste site designed with a liner or situated in soils with sufficiently low permeability to either partially or completely contain leachate is designed with a leachate management system that can effectively remove leachate, prevent surface seepage, and promote adequate settlement to permit final reclamation.
All surface water drainage ditches, culverts, and other drainage control structures are designed for a rainfall event measured in terms of the depth of the rainfall occurring within a 24-hour period and having an expected recurrence interval of once in 100 years.
The final slopes of the completed mining waste site will be no greater than 50 percent, unless the mining waste site is specifically designed for a final use compatible with other slopes.
The final cover design for the mining waste site is based on the results of the mining waste characterization and engineering needs identified in studying the mining waste site feasibility.
Provisions are made for collection and treatment of leachate for all areas designed to contain leachate.
The mining waste site is located and designed, and will be constructed and operated, so that any liner system or naturally occurring soil barrier is compatible with all mining waste that is disposed of or stored in the mining waste site.
For any dam, sufficient freeboard, measured from the inside of the top of the dam, to contain a rainfall event measured in terms of the depth of the rainfall occurring within a 24-hour period and having an expected recurrence interval of once in 100 years and to prevent overtopping by waves during such a rainfall event or a minimum of 2 feet of freeboard, whichever is greater, will be provided.
Drainage or filter bed material has been selected and designed to promote drainage, reduce the potential for piping, and be stable under leaching conditions.
Material used in earth embankments or drainage or filter beds will be free of vegetation, organic soils, frozen soils, and other extraneous matter that could affect the compactibility, density, permeability, or shear strength of the finished embankment.
Embankment materials and drainage or filter bed materials will be compacted to 90 percent of the maximum dry density as determined by the standard proctor compaction test, ASTM D698, or to a greater density as necessitated by the embankment height, and the materials will be compacted in appropriate layers as determined through the slope stability analysis, except that compaction and crushing of waste rock for use outside an earth core is not required.
Emergency spill containment areas will be provided near the tailings pipeline in case of power or pipeline failure.
Tailings pipelines will be self-draining to the tailings area or to an emergency spill containment area.
The mining waste site is located in the same watershed as the surface facilities for the mining unless it is not practicable to locate the mining waste site in the same watershed as the surface facilities for the mining, as determined on a site specific basis.
The disposal of the mining waste will minimize the discharge of environmental pollutants to groundwater to the extent practicable.
Tailings pipelines are as short as practicable.
Upstream rainfall catchment areas are minimized.
The outside of the top of any dam is higher than the inside of the top of the dam so that runoff from the top is forced to the inside of the dam.
The mining waste site design includes staged reclamation, if practicable.
(8) Limitation on regulation of certain mining waste.
The department may not regulate the use of mining waste in reclamation or in the construction of any facility or structure on a mining site except through the department's review of the mining plan and reclamation plan and the approval of the application for the mining permit.
(9) Applicability of other laws.
and VIII of ch. 289
and rules promulgated under those subchapters do not apply to a mining waste site, to the disposal of mining waste in a mining waste site, or to mining wastes used in the reclamation or construction of facilities and structures on the mining site.
