Revise mine reclamation laws

This bill revises Montana's mine reclamation laws by updating definitions and clarifying requirements for mining permits. It directly affects mining companies and the state's environmental review board by establishing clearer standards for terms like "abandoned" operations, "adjacent area," and "approximate original contour" for land restoration. The legislation grants rulemaking authority to the department and specifies how hydrologic and geologic information must be included in permits, while also defining what constitutes an amendment to a mining plan. These changes aim to improve consistency in how mining operations are regulated and how land must be restored after extraction.
