Class II Underground Injection Control (MiSTAR)

Electronic filing of Class II well injection data and documents is accomplished using the Michigan’s State Tracking and Reporting (MiSTAR) system. MiSTAR replaces paper data submittals by allowing the electronic submittals of all the Class II well injection reporting requirements. All owners and operators of Class II wells are required to use MiSTAR to electronically submit data to fulfill the regulatory requirements of Class II injection well reporting per Part 615 of the NREPA.

MiSTAR Class II well injection well reporting includes the Monthly/Annual Injection Well Operating Report (formerly form EQP 7609,) Standard Annular Pressure Test (formerly form EQP 7606), Notification of Loss of Mechanical Integrity, Notification of Scheduling MIT, and Quarterly Annulus Fill Reports. Documents such as Chemical Analysis of Injectate, Pressure Gauge Calibration Data, MIT Charts, and other documents can be submitted in a PDF format.
