Any considerations of whether substantial harm to public health and safety or to the environment will occur shall consider the total effect of the proposed reagents on the receiving watercourse. Reagent characteristics to investigate include chemical oxygen demand, biochemical oxygen demand, biodegradability, effects on local aquatic life (plant and animal), and effects on the total dissolved solids concentration and hardness of the receiving stream.
Reagents that consist of or contain water soluble salts or metals shall not be used if their use results in a discharge to the waters of the state not in compliance with chs. 281
Adequate treatment as required pursuant to chs. 281
, Stats., shall be provided for reagents which are biological nutrients so as not to result in excessive eutrophication of aquatic ecosystems.
Reagents shall not be used or stored on the mine site if they are not approved in the plan of operation pursuant to s. NR 182.09
or the mining plan pursuant to s. NR 132.07
, except for reagents for laboratory or testing, research or experimental purposes.
Every reasonable effort should be made to reduce and control the production of contaminated water.
Contaminated water, including liquid effluents, from whatever source associated with the project should be collected, stored, recycled or treated to the maximum extent practicable.
Contaminated nonpoint source runoff from disturbed areas within the mining site should be collected and treated in a manner which facilitates monitoring, maximum practicable recycling reuse and consumption within the mining operation. Nonpoint sources of water pollution should be minimized to the extent practicable. Also to the extent practicable, the frequency and need for point source discharges of waste water to surface waters of the state shall be regulated pursuant to ch. 283, Stats.
Provisions for critical back-up equipment in the event of operation equipment breakdown shall be made.
Design and operation specifications for mine site facilities should include contingencies for emergency conditions. Such contingencies may include emergency power supplies, equipment redundancies or temporary holding facilities.
Any mine site permitted pursuant to this chapter shall be designed, constructed, maintained, operated and reclaimed in such a manner so as to protect groundwater quality and quantity in accordance with the standards of ch. NR 182
Waste containing potentially harmful concentrations of acid generating material should not be used for purposes such as the construction of parking lots or roads in mine sites.
Mine site facilities should be designed to minimize surface area disturbance.
Where practicable, elevation differences in water-based transport systems should be utilized for gravity flows to minimize pumping facilities and pressures.
Tailings transport systems, if not buried, should be designed to provide for emergency tailings conveyance or storage should a pipeline break, plug, freeze or require repairs and be made accessible for inspection, emergency repair and maintenance. Location of emergency spill areas must be consistent with the prevention of environmental pollution of surface waters and with the standards of ss. NR 182.07 (2)
, 132.06 (4)
. In the event of a power failure, tailing pipelines should be self draining to the tailings area or to an emergency spill area or standby pumps and pipelines or standby power should be provided. In some cases (e.g., a long pipeline over rough country), several spill areas may have to be provided.
If practicable, all liquid effluents from a mine waste facility should be directed to a common point (for treatment if necessary) before discharge to a natural watercourse. If practicable, treated wastes should not be directed to more than one watershed.
In general, sanitary wastes should not be directed to a mill tailings control area without appropriate treatment.
With the exception of subs. (2)
, the provisions of this section shall not apply to a mining operation in existence on May 21, 1978 and for which a mining permit application approved by the department was on file on the date these rules became effective, except to the extent there is a change in the mining operation requiring a modification of the mining permit under these rules.

To the extent practicable no person shall establish, construct, operate or maintain the use of property for any mining related buildings, roads, ponds, or other construction within the following areas, except pursuant to an exemption granted under s. NR 132.19
Within 1,000 feet of any navigable lake, pond or flowage.
Within 1,000 feet of the nearest edge of the right-of-way of any of the following: any state trunk highway, interstate or federal primary highway; the boundary of a state public park; the boundary of a scenic easement purchased by the department or the department of transportation; the boundary of a designated scenic or wild river; a scenic overlook designated by the department by rule; or a bike or hiking trail designated by the United States congress or the state legislature; unless, regardless of season, the site is visually inconspicuous due to screening or being visually absorbed due to natural objects, compatible natural plantings, earth berm or other appropriate means, or unless, regardless of season, the site is screened so as to be aesthetically pleasing and inconspicuous as is feasible.
Within areas so that noncompliance will result with other applicable federal and state laws and regulations.
This section shall not apply to a mining operation in existence on May 21, 1978, and for which a mining permit application approved by the department was on file on the date these rules became effective.

The department may grant exemptions from the requirements of this chapter, if such exemptions are consistent with the purposes of this chapter and will not violate any applicable federal or state environmental law or rule.
All requests for exemptions by the applicant shall be made at least 90 days before the hearing under s. 293.43
, Stats., unless the condition which is the basis for the requested exemption is unknown to the applicant prior to that time or for good cause shown.
If an applicant applies for an exemption less than 90 days before the hearing, the portion of the hearing concerning that exemption request shall be held no earlier than 90 days after receipt of the application for the exemption.
Requests for exemptions may be made by any party to the hearing other than the applicant up to 30 days before the hearing. Any request for exemption made prior to the hearing shall be determined as part of that proceeding.
The burden of proof for seeking an exemption is upon the person seeking it.
Any party to the hearing may request more stringent standards or requirements for any provision of this chapter.
Any application for an exemption made after the hearing shall be determined by the following procedure:
The application shall be in writing and shall include documentation justifying the need for the exemption, describing the alternatives and explaining why the exemption was not sought before the hearing.
If the application does not involve an exemption from a requirement of this chapter the department shall issue a decision on the application within 15 days of receipt of the application.
If the application involves an exemption from a requirement of this chapter, within 10 days of the application the department shall publish a class 1 notice under ch. 985, Stats.
