Language for a ballot measure that would restrict mining activities in Michigan has been approved by a state election board, AP reports.
Michigan Save Our Water Committee, the group organizing the ballot initiative, says on its website that it plans to collect 400,000 signatures by May 2010 so that the measure to restrict sulfide and uranium mining can appear on the ballot in November.
The group says that the ballot measure is necessary in order to prevent damage to Michigan waters. Sulfide mining is associated with acidic mine drainage.
State departments of Natural Resources and Environmental Quality have granted permits for a controversial nickel sulfide mine planned by Rio Tinto subsidiary, Kennecott Eagle Minerals, in the Yellow Dog Plain northwest of Marquette.
In February Rio Tinto announced that was placing development of that mine on hold until market conditions improve. Opponents of the planned mine say they hope to build a broad-based grassroots campaign to ban sulfide mining before demand for metals rebounds.
