Deepening of withdrawal facilities.

At any time that the holder of a valid groundwater right proposes to deepen a withdrawal facility, the modification of the facility shall be made in such a manner as to preclude the occurrence of cascading waters. Such a facility shall not be deepened to tap a different body of public groundwater, or a different aquifer zone where such zones have been determined by the department, without further appropriate authorization from the department.
