Michigan Compiled Laws, Chapter 324. Natural Resources and Environmental Protection § 324.3123

Sec. 3123. (1) The department shall send invoices for the groundwater discharge permit fees under section 3122  1 to all permit holders by January 15 of each year. Fees will be charged for all facilities authorized as of December 15 of each calendar year. Payment shall be postmarked no later than March 1 of each year. Failure by the department to send an invoice by the deadline, or failure of a person to receive an invoice, does not relieve that person of his or her obligation to pay the annual groundwater discharge permit fee. If the department does not meet the January 15 deadline for sending invoices, the annual groundwater discharge permit fee is due not later than 45 days after receiving an invoice. The department shall forward money collected pursuant to this section to the state treasurer for deposit into the groundwater discharge permit fund established under section 3124.  2

(2) The department shall assess a penalty on all fee payments submitted under this section after the due date. The penalty shall be an amount equal to 0.75% of the payment due for each month or portion of a month the payment remains past due. Failure to timely pay a fee imposed by this section is a violation of this part and is cause for revocation of a permit issued under this part and may subject the discharger to additional penalties pursuant to section 3115.  3

(3) The attorney general may bring an action for the collection of the groundwater discharge permit fees imposed under this section.
