Nonferrous mining prohibited if sulfate levels increase in waters within the Rainy River headwaters, and penalties established.

This bill prohibits the state from leasing land or issuing permits for nonferrous mining in the Rainy River headwaters if the mining activity causes sulfate levels in nearby water to rise by even one part per million. It requires that any mining permits in this area include strict conditions to prevent any increase in sulfate concentrations and mandate public monitoring of water quality data. Additionally, the legislation establishes civil penalties and orders to suspend mining operations if sulfate levels exceed the zero parts per million threshold. The law applies specifically to state-owned or administered lands within the designated Rainy River headwaters basin.
