Mich. Comp. Laws § 259.87: Airports and facilities; rejection of application for permission to operate.

Sec. 87.

In any case in which the department rejects an application for permission to operate an airport, landing field, or other aeronautical facility, or in any case where the department shall issue any order requiring certain things to be done, it shall set forth its reasons for the order and shall state the requirements to be met before approval will be given. In any case in which the department considers it necessary, the department may order the closing of any airport, landing field, or other aeronautical facility, until compliance is made with the requirements ordered by the department.

A facility shall not be licensed or approved that requires aircraft to be airborne under a bridge or power line during the approach to or takeoff from a landing area, or that requires aircraft to fly in a manner that may endanger persons or property.
