Mich. Comp. Laws § 324.80159
A person shall not place a beacon or buoy, other than a mooring buoy, in the waters of this state except as authorized by a permit issued by the department pursuant to part 13. The department may issue a permit for the placing of buoys or beacons in the waters of this state to mark obstruction to navigation, to designate bathing areas, to designate vessel anchorages, or for any other purpose if it will promote safety or navigation. An application for a permit shall contain information required by the department. If buoys or beacons are placed in the waters of this state without a permit having been issued, the department may order their removal. If, in the judgment of the department, buoys or beacons authorized by the department are found to be improperly placed, the reason for their placement no longer exists, or the buoys or beacons do not conform to the uniform system of marking established by state regulation, the department may revoke the permit authorizing their placement and may order their removal. Revocation of permits and orders of removal shall be by written notice to the person placing the buoys or beacons or to the person to whom the permit was issued at his or her last known address, directing the removal within a specified time. The person to whom the notice is directed shall remove the buoys or beacons in accordance with the instructions. If the person fails to remove the buoys or beacons within the specified time, the department may cause their removal, and the cost and expense of the removal shall be charged against the person authorized to place the buoys or beacons or, where authorization has not been granted, the person placing such buoys or beacons and shall be recoverable through any court of competent jurisdiction.
