A bipartisan group of state lawmakers representing Michigan's Upper Peninsula is criticizing a possible ballot proposal that would ban some types of mining.
The lawmakers said Tuesday the proposal is an attack on the region's economic interests.
The proposal sponsored by the Michigan Save Our Water Committee would ban uranium mining and restrict sulfide and other types of mining. Supporters say the measure is needed to protect the Great Lakes and other aspects of Michigan's environment.
Supporters would need to collect more than 300,000 signatures to make the 2010 ballot.
The statement against the proposal was issued by Democratic lawmakers Mike Prusi, Michael Lahti, Steven Lindberg and Judy Nerat along with Republican Jason Allen.
