AB917,47,1611 (b) The department determines, based on information provided by an applicant
12for a permit under s. 293.49 and verified by the department, that a mining operation
13that operated in a sulfide ore body which, together with the host nonferrous rock, has
14a net acid generating potential in the United States or Canada has been closed for
15at least 10 years without the pollution of groundwater or surface water from acid
16drainage at the tailings site or at the mine site or from the release of heavy metals.
AB917,47,22 17(2m) (a) The department may not base its determination under sub. (2) (a) or
18(b) on any mining operation that has been listed on the national priorities list under
1942 USC 9605 (a) (8) (B) or any mining operation for which the operator is no longer
20in business and has no successor that may be liable for any contamination from the
21mining operation and for which there are no other persons that may be liable for any
22contamination from the mining operation.
AB917,48,223 (b) The department may not base its determination under sub. (2) (a) or (b) on
24a mining operation unless the department determines, based on relevant data from
25groundwater or surface water monitoring, that the mining operation has not caused

1significant environmental pollution from acid drainage at the tailings site or at the
2mine site or from the release of heavy metals.

11performance of all of the requirements of this chapter and all rules adopted by the
12department under this chapter. The bond shall be furnished by a surety company
13licensed to do business in this state. In lieu of a bond, the operator may deposit cash,
14certificates of deposit, or government securities with the department. Interest
15received on certificates of deposit and government securities shall be paid to the
16operator. The amount of the bond or other security required shall be equal to the
17estimated cost to the state of fulfilling the reclamation plan, in relation to that
18portion of the site that will be disturbed by the end of the following year. The
19estimated cost of reclamation of each prospecting or mining site shall be determined
20by the department on the basis of relevant factors including, but not limited to,
21expected changes in the price index, topography of the site, methods being employed,
22depth and composition of overburden and depth of nonferrous metallic mineral
23deposit being mined.

AB917,191 6Section 191 . NR 132.06 (4) of the administrative code is created to read:
AB917,55,237 NR 132.06 (4) The department has been directed, pursuant to ch. 421, laws of
81977, to assure that mining activities conducted in this state result in a minimization
9of disturbance to wetlands. The legislature has also directed, in ch. 377, laws of 1977,
10that department rules relating to metallic mining wastes take into consideration the
11special requirements of metallic mining operations in the location, design,
12construction, operation and maintenance of sites and facilities for the disposal of
13such wastes as well as any special environmental concerns that will arise as a result
14of the disposal of the same. The department has established, in s. NR 1.95 an overall
15framework for its decisions affecting wetlands. It is, therefore, the intent of this
16subsection to implement these directives recognizing that, depending on the location
17and site conditions involved in a particular case, it may be relatively easy to avoid
18entirely the use of wetlands in some cases while being virtually impossible to avoid
19their limited and carefully contemplated use in others and that the goal of the siting
20process shall be the selection of sites that are most favorable taking into account all
21pertinent factors. For purposes, therefore, of administering these directives and
22rules and acting on permits, licenses and approvals, the following standards shall be
23applied:
AB917,56,224 (a) The objective of the applicant's site selection process for mining facilities,
25and for the disposal or storage of wastes or materials produced by such activities,

1shall be the selection of a viable site that would result in the least overall adverse
2environmental impact.
AB917,56,93 (b) The applicant's site selection process shall include the identification and
4analysis of various alternatives so that a legitimate comparison between the most
5viable sites can be made by the department, realizing that a comparison will be made
6between several sites, all of which may have some imperfections with regard to
7environmental acceptability and none of which, in some cases, may be found to be
8environmentally acceptable as a result of compliance with s. 1.11, Stats., and other
9applicable Wisconsin laws.
AB917,56,1910 (c) To ensure compliance with the requirement to minimize the disturbance of
11wetlands, the applicant shall identify and the department shall analyze viable sites
12which would result in the least overall adverse environmental impact and which
13would also avoid the use of any wetlands. If such sites avoiding the use of wetlands
14cannot be identified pursuant to the standards in this subsection, then the applicant
15shall identify and the department shall analyze those viable sites which would result
16in the least overall adverse environmental impact and which would also utilize,
17consistent with minimizing total environmental impacts, the least acreage and the
18least valuable wetlands directly and which would cause the least adverse impact on
19the wetlands and waters of the state outside the proposed area of use.
AB917,56,2420 (d) The use of wetlands for mining activities, including the disposal or storage
21of mining wastes or materials, or the use of other lands for such uses which would
22have a significant adverse effect on wetlands, are presumed to be unnecessary unless
23the applicant demonstrates, taking into account economic, environmental, technical,
24recreational and aesthetic factors, that the site proposed for use:
AB917,56,2525 1. Constitutes a viable site;
AB917,57,2
12. Is the alternative which causes the least overall adverse environmental
2impact;
AB917,57,93 3. Will be used in a manner so as to minimize the loss of wetlands functions
4which those wetlands may serve with respect to related wetlands or other waters of
5the state, or both, outside the proposed area of use. As used in this paragraph, a
6presumption shall not be construed to be a prohibition, but rather the creating of a
7burden of proof on the applicant to demonstrate by the preponderance of evidence
8that it has complied with all the siting principles and standards of this subsection.
9As used in this section, viable means technically and economically feasible.
AB917,57,2510 (e) With respect to mining activities sited, in whole or in part, in wetlands and
11predating these rules as well as ch. 377, laws of 1977, the use of such wetlands for
12such activities shall be deemed necessary hereunder and the site of such use shall
13be deemed a viable site. The standards of minimization herein established to the
14extent applicable to such preexisting activities by reason of s. 293.13 (2) (c) 8., Stats.,
15shall be so applicable only to the extent specified in s. 293.91 (2), Stats. Furthermore,
16any additional activities undertaken in wetlands by an applicant subsequent to the
17effective date of these rules, which additional activities are undertaken to bring
18activities of the applicant, which were sited in wetlands prior to these rules, into
19prompt compliance with chs. 30, 281 and 283, Stats., as well as regulations, orders
20and decisions thereunder, shall be deemed to be necessary so long as the applicant
21demonstrates that, taking into account economic, environmental, technical,
22recreational and aesthetic factors, the site proposed for use by such additional
23activities will be used in a manner so as to minimize the loss of wetlands and the net
24loss of functions which those wetlands may serve with respect to related wetlands
25or other waters of the state, or both, outside the proposed area of use.
AB917,58,3
1(f) The department shall give special consideration to a site where it finds that
2the degree of necessary improvement is of such extent and expense that compliance
3cannot be accomplished without affecting wetlands.
AB917,58,64 (g) The applicant shall assist in the evaluation of environmental impacts as
5mandated herein. All of the applicable following wetlands functions and values shall
6be considered except as provided in par. (h):
AB917,58,227 1. `Biological functions.' Wetlands are environments in which a variety of
8biological functions occur. In many cases, wetlands are very productive ecosystems
9which support a wide diversity of aquatic and terrestrial organisms. Many wetland
10areas are vital spawning, breeding, nursery or feeding grounds for a variety of
11indigenous species. Wetlands are sometimes the habitats for state or federally
12designated rare, threatened or endangered species. Evaluation of the biological
13functions should include consideration of the kinds, numbers and relative
14abundance and distribution of plant and animal species supported by the area, net
15primary productivity of plant communities, wildlife production and use, and the
16kinds and amount of organic material transported to other aquatic systems as a
17potential energy source for consumer organisms in those systems. Habitat
18evaluation should consider the short- and long-term importance of the wetlands to
19both aquatic and terrestrial species. In addition, the evaluation should include any
20specialized wetland functions essential for an organism to complete its life cycle
21requirements such as cover, spawning, feeding and the like. Each wetland under
22consideration should be evaluated on a site specific basis.
AB917,59,1123 2. `Watershed functions.' In addition to their biological functions, wetlands
24may serve important physical and chemical functions with respect to other wetlands
25and waters of the state. A specific wetland, or set of wetlands, may play a critical role

1in maintaining the stability of the entire system to which it is physically and
2functionally related. This functional role may include the maintenance of both the
3hydrologic patterns and the physical and chemical processes of related wetlands and
4other related waters of the state. Evaluation of wetland functions requires a
5thorough analysis of the manner and extent to which the wetland serves to maintain
6the hydrologic, physical and chemical processes of the larger ecosystem to which it
7belongs. Factors to be considered in the evaluation process are discussed below. The
8use of non-wetland areas may alter the hydrologic, chemical and physical processes
9of wetlands outside the proposed area of use. The possibility of such impacts from
10the use area into wetlands and other waters of the state outside the proposed area
11of use should be carefully considered.
AB917,60,1712 2c. `Hydrologic support functions.' A particular wetland may function to
13maintain the hydrologic characteristics, and thereby the physical and chemical
14integrity of an entire aquatic ecosystem. Assessment of the hydrologic support
15function shall consider the effects that modifications of a particular area could have
16on the hydrologic relations to the whole wetland or aquatic ecosystem, and on the
17cumulative effects of piecemeal alterations. Evaluation of wetlands hydrologic
18functions shall include consideration of the wetland's location and topographic
19position, the areal extent of the wetland within the associated system, the degree of
20connection with other wetlands and waters of the state, and the hydrologic regime.
21Hydrologic regime refers to the hydrologic characteristics of a wetland such as the
22source of the water, its velocity, depth and fluctuation, renewal rate and temporal
23patterns on timing. The water source determines ionic composition, oxygen
24saturation, and potential pollutant load. Velocity affects turbulence and the ability
25of the water to carry suspended particulate matter. Water depth and fluctuation

1patterns have a critical influence on the vegetation, wildlife, and physical-chemical
2properties of the sediments and overlying waters. Renewal rate describes the
3frequency of replacement of the water which depends on water depth and volume,
4frequency of inundation and velocity. The temporal pattern refers to the frequency
5of inundation and its regularity or predictability. The hydrologic regime of a wetland
6influences the biological availability and transport of nutrients, detritus and other
7organic and inorganic constituents between the particular wetland and other water
8bodies. Other facets of the hydrologic regime may be considered in specific cases.
9The location and topographic position of any particular wetland in relation to other
10water systems determine in part the degree to which they are hydrologically
11connected. The strongest hydrologic connections are likely to occur between
12wetlands and other water systems which exchange water frequently and/or are
13nearest to each other. The areal extent of any particular wetland in relation to the
14total area of the surrounding watershed is an important criterion in evaluating the
15hydrologic support function. This includes the relative spatial relationships between
16specific areas under study and the total area of the adjacent wetland and any open
17water areas in the watershed.
AB917,60,2418 2f. `Groundwater function.' Groundwater may discharge to a wetland,
19recharge from a wetland to another area, evaporate from, and/or flow through a
20wetland. The direction and rate of groundwater flow in a given wetland may change.
21The criteria that should be considered for their influence on the recharge potential
22include the total areal extent of wetlands and other waters in the particular drainage
23basin, and the hydrologic characteristics of the associated aquifer or aquifers
24including porosity, permeability and transmissivity.

12i. `Storm and flood water storage.' Some wetlands may be important for
2storing water and retarding flow during periods of flood or storm discharge. Even
3wetlands without surface water connections to other water bodies may serve this
4function. Such wetlands can reduce or at least modify the potentially damaging
5effects of floods by intercepting and retaining water which might otherwise be
6channelled through open flow systems. The importance of a given wetland for storm
7and flood water storage may be modified by the cumulative effects of the proposed
8activities and previous activities within the watershed. The flood storage capacity
9of a particular wetland is primarily a function of its area, basin shape, substrate
10texture and previous degree of saturation. In general, the greater the area of the
11wetland and the coarser the texture of the substrate, the greater the potential for
12flood water storage, given unsaturated field conditions. Similarly, wetland
13vegetation is an important factor in reducing the energy of flood or storm water.
AB917,62,214 2m. `Shoreline protection.' Wetlands also function to dissipate the energy of
15wave motion and runoff surges from storms and snowmelt, and thus lessen the
16effects of shoreline erosion. Wave action shielding by wetlands is not only important
17in preserving shorelines and channels, but also in protecting valuable residential,
18commercial and industrial acreage located adjacent to the aquatic ecosystems. The
19capacity of a particular wetland to act as an erosional buffer for a shoreline depends
20on such factors as the vegetation characteristics, the shape and size of the wetland
21and the adjacent shoreline morphology. The protection of shorelines by wetlands
22depends primarily on the floristic composition, structure and density of the plant
23community. Shoreline morphology along with fetch, adjacent bottom topography
24and wetland vegetation are important considerations in evaluating a wetland for its
25shoreline protection functions. Wetlands along shorelines with long fetches are

1likely to be associated with major waters of the state and shall not be considered for
2use.
AB917,62,123 2p. `Other watershed functions.' A wetland may perform a variety of other
4important functions within a watershed. Wetlands may degrade, inactivate, or store
5materials such as heavy metals, sediments, nutrients, and organic compounds that
6would otherwise drain into waterways. However, wetlands may subsequently
7release potentially harmful materials if the wetland soil is disturbed or its
8oxidation-reduction conditions altered. Potential alterations of these processes
9must be considered in the analysis, especially with regard to impacts on wetlands
10outside the proposed area of use. In assessing the importance of a particular wetland
11to the performance of watershed functions which influence the physical, chemical
12and biological properties of related waters, the following shall be considered:
AB917,62,1313 a. Density and distribution of plants;
AB917,62,1414 b. Area, depth and basin shape;
AB917,62,1515 c. Hydrologic regime;
AB917,62,1616 d. Physical, chemical and biological properties of the water and soil;
AB917,62,1717 e. Relationship of wetland size to watershed size;
AB917,62,1818 f. The number and size of other wetlands remaining in that watershed;
AB917,62,1919 g. Topography of the watershed;
AB917,62,2120 h. Position of the wetland within the watershed relative to springs, lakes, rivers
21and other waters;
AB917,62,2322 i. Land use practices and trends within the watershed, or the likelihood of
23nutrient, sediment or toxin loads increasing.
AB917,63,624 3. `Recreational, cultural and economic value.' Some wetlands are particularly
25valuable in meeting the demand for recreational areas, directly or indirectly, by

1helping to maintain water quality and providing wildlife habitat. Examples of
2recreational uses include: hunting, canoeing, hiking, snowshoeing, and nature
3study. To some people and cultures certain wetlands provide an important part of
4their economic base and/or contribute to their cultural heritage. In assessing the
5recreational, cultural and economic potential of a particular wetland, the following
6should be considered:
AB917,63,77 a. Wetland type;
AB917,63,88 b. Size;
AB917,63,99 c. Suitability and compatibility for the different types of recreational uses;
AB917,63,1010 d. Legal access.
AB917,63,1111 e. Accessibility without damage to other wetland values or functions;
AB917,63,1212 f. Proximity to users;
AB917,63,1313 g. Position in relation to lakes, rivers and other waters;
AB917,63,1514 h. Whether it provides habitat for or produces species of recreational, cultural
15or economic interest; and
AB917,63,1816 i. Whether the products of some wetlands species (e.g., wild rice, furbearers,
17fish) have special cultural value and/or provide a significant portion of the economic
18base for the people of a region.
AB917,64,219 4. `Scarcity of wetland type.' Certain wetland types (e.g., fens, wild rice lakes)
20which are statewide or regionally scarce possess special resource significance.
21Scarcity or rareness depends on the frequency of occurrence of the type, the area of
22the type in existence prior to settlement, the historical conversion of the type and its
23resultant degree of destruction, and the amount of similar habitat in the present
24landscape of the region. In assessing the scarcity of a particular wetland, a

1comparative measure of the commonness among all wetland types and the degree to
2which wetlands of all types occur in the surrounding landscape should be considered.
AB917,64,113 5. `Aquatic study areas, sanctuaries and refuges.' Through various local, state
4and federal actions, large areas of the nation's wetlands have been designated and
5preserved by public agencies for scientific study, and the protection of aquatic and
6terrestrial habitats. Many public and private groups have also established
7sanctuaries and refuges in wetlands. Wetland areas that are legally and/or
8administratively controlled as such, or that are included or nominated for inclusion
9in the national register of natural landmarks, could be comparatively important.
10Wetland areas of significant social, cultural, or historic value, such as known
11landmarks, are considered important.
