The department shall serve as the central unit of state government to ensure that the impact from mining and reclamation on the air, lands, waters, plants, fish, and wildlife in this state will be minimized and offset to the extent practicable. The administration of occupational health and safety laws and rules that apply to mining remain exclusively the responsibility of the department of safety and professional services. The powers and duties of the geological and natural history survey under s. 36.25 (6) remain exclusively the responsibility of the geological and natural history survey. Nothing in this section prevents the department of safety and professional services and the geological and natural history survey from cooperating with the department in the exercise of their respective powers and duties.
