Regarding Tariffs for Regulated Services

For your convenience copies of tariffs for services regulated by the Michigan Public Service Commission (MPSC) are posted here

These tariffs are on file with the MPSC, the filed tariffs are the official reference for tariff information. 

Although precautions have been taken to ensure that tariffs on the web site are identical to the filed versions, undetected production errors may cause discrepancies to occur. In the case of any discrepancies, the official tariffs on file with the MPSC will prevail.
