MADISON, WI (WTAQ) - Wisconsin’s Republican majority will announce changes late Monday afternoon to the proposed mining bill.

Four sponsors of the package will announce amendments.

It remains to be seen how far the GOP will go to try and satisfy Democrats who want assurances that the environment would not be hurt by mining – and that opponents can still challenge what the DNR decides.

The current bill has changes to wetlands and water standards as proposed by Gogebic Taconite, the Florida company that plans to open an iron ore mine in far northern Wisconsin if the firm can get what it wants from lawmakers.

The bill also removes the ability to challenge DNR mining decisions. It sets a 420-day deadline for the DNR to act on a mining application.

The Assembly and Senate mining panels are scheduled to vote Wednesday on the legislation.

The measure would then go to the full Legislature.
