Revise siltation structure capacity at mines
Senate Bill 365 revises the capacity requirements for siltation structures at strip and underground mines in Montana. The bill amends Section 82-4-231, MCA, which outlines the process for mine operators to submit and obtain approval for reclamation plans. It grants rulemaking authority to the relevant department to establish specific requirements for these structures. The changes aim to ensure effective water control measures are included in reclamation plans to prevent damages from soil erosion and water pollution.
