A bill to reinstate the Bull Mountains Mining Plan Modification, and for other purposes.

This bill (S 4431) directs the Secretary of the Interior to reinstate a previously approved mining plan modification for the Bull Mountains Mine No. 1 in Montana. It specifically requires the reinstatement of Amendment 3 to the mine's plan within 30 days of the bill's enactment, without any changes. The modification will remain in effect until the Montana Department of Environmental Quality determines that mining under the plan is complete. This bill directly affects the Bull Mountains Mine operations and Montana's regulatory oversight.
