MI HB4324

Permits the Department of Natural Resources to approve renewal applications for mining or excavation permits affecting inland lakes within 30 days without requiring additional studies if the project scope has not materially increased.

Defines "materially increased" as an increase of 10% or more to the horizontal or vertical extent of excavation below the water table compared to the maximum excavation allowed under the original permit.

Exempts the automatic approval requirement if the department demonstrates by a preponderance of sound scientific evidence that the originally permitted activity has had a materially adverse effect on human health or the environment.

Caps the application fee for permit renewals under this section at $250.00 for mining operations that have created or affected inland lakes and have not materially increased in scope.
