Groundwater thermal exchange devices permits changes provisions

This bill updates the rules for issuing permits related to groundwater thermal exchange devices in Minnesota, which are systems that use underground water to heat or cool buildings. It requires property owners to apply for a permit and pay a fee before reinjecting water into the same aquifer from which it was drawn. The legislation sets limits on the number of permits allowed for small and large systems based on their water capacity and mandates regular inspections to ensure safety. Additionally, the bill clarifies that these devices must also comply with existing water-use permit requirements enforced by the commissioner of natural resources.
