AB426,41,6 5(1) That attracting and aiding new mining enterprises and expanding the
6mining industry in Wisconsin is part of Wisconsin public policy.
AB426,41,9 7(2) That mining for nonferrous metallic minerals is different from mining for
8ferrous minerals because in mining for nonferrous metallic minerals, sulfite
9minerals react, when exposed to air and water, to form acid drainage.
AB426,41,13 10(3) That if the mineral products and waste materials associated with
11nonferrous metallic sulfide mining operations are not properly managed and
12controlled, they can cause significant damage to the environment, affect human
13health, and degrade the quality of life of the affected community.
AB426,41,16 14(4) That the special concerns surrounding nonferrous metallic mining warrant
15more stringent regulatory measures than those warranted for ferrous mining
16operations.
AB426,41,19 17(5) That the provisions in ch. 293, 2009 stats., are a deterrent to ferrous mining
18in this state and are not necessary to ensure that ferrous mining will be conducted
19in an environmentally sound manner.
AB426,41,23 20(6) That simplifying and shortening the permitting process for ferrous metallic
21mineral mining when compared to nonferrous metallic mineral mining, as
22Minnesota and Michigan have done, will encourage ferrous metallic mineral mining
23in Wisconsin and create jobs and generate resources for the state.
AB426,42,5 24(7) That because of the fixed location of ferrous mineral deposits in the state,
25it is probable that mining those deposits will result in adverse impacts to areas of

1special natural resource interest and to wetlands, including wetlands located within
2areas of special natural resource interest and that, therefore, the use of wetlands for
3bulk sampling and mining activities, including the disposal or storage of mining
4wastes or materials, or the use of other lands for mining activities that would have
5a significant adverse impact on wetlands, is presumed to be necessary.
