Bill Overview

Analyzed Economic Effects

3 provisions identified: 1 benefits, 1 costs, 1 mixed.

Stronger water and land safeguards

The law tightens what counts as “material damage” outside a mine’s permit area. It protects surface and groundwater uses, alluvial valley farm lands, and buildings from measurable harm. It also requires solid hydrologic data for permit review. The department uses federal or state data when available, or applicant data if not. A permit is not approved until this information is in the application.

Proof of money for mine cleanup

Mining permit applicants must show bonding or other financial assurance for reclamation. The department sets what proof counts by rule. This ensures funds are available to clean up mines under sections 82-4-231 to 82-4-234.

Federal check and immediate, retroactive mining rules

Any part of this law is void if the U.S. Secretary of the Interior disapproves it under 30 CFR 732. The department must notify the code commissioner within 15 days of that disapproval. The law takes effect on passage and approval. It also applies to pending but undecided court reviews and related actions.
