Mich. Admin. Code R. 324.812
Rule 812.
If an injection well ceases operating for the purpose for which it was intended for 1 year, then a permittee shall plug the well or request temporary abandonment status for the well in writing. The request for temporary abandonment status shall be pursuant to R 324.511. The temporary abandonment status may be granted by the supervisor if, after application and justification by the permittee, the supervisor determines that waste will be prevented. When approving the temporary abandonment status or subsequent extensions, the supervisor may require special actions and monitoring by the permittee to ensure the prevention of waste and endangerment of underground sources of drinking water. If temporary abandonment status is not granted, then the permittee of the injection well shall plug the well. The permittee may petition the supervisor for a hearing to show cause why the well should not be plugged. This rule supersedes R 324.209 for injection wells.
