Montana Resources wants to raise the height of the impoundment by 45 to 75 feet over about 336 acres.
DEQ gave draft approval of the expansion in August.
The state is now is now determining the scope of analysis for the proposed expansion. Scoping started today, and runs through October 15.
There will be a public meeting October 4 in Butte that will include an open house and presentation on DEQ’s Environmental Impact Statement and permitting process. The public will then have a chance to give oral and written testimony.
