"Gov. Scott Walker plans to sign a Republican bill lifting Wisconsin’s nearly 20-year ban on gold and silver mining — a ban he himself helped put in place as a legislator.
Lawmakers passed statutes in 1998 that require sulfide mining applicants to show a similar mine has operated in North American for 10 years without polluting and a similar mine has been closed for 10 years without polluting. State environmental officials have never made a final determination that any applicants ever met those standards.
Walker voted for the ban as a member of the Assembly."
