Status: in_force

Sec. 3118.

(1) Except as otherwise provided in this section, until October 1, 2029, the department shall collect the following stormwater discharge fees from persons that apply for or have been issued stormwater discharge permits:

(a) A 1-time fee of $400.00 for a permit related solely to a site of construction activity for each permitted site. The fee must be submitted with the application for an individual permit or for a certificate of coverage under a general permit. For a permit by rule, the fee must be submitted by the construction site permittee with the notice of coverage. A person that needs more than 1 permit may submit a single payment for more than 1 permit and receive appropriate credit. Payment of the fee under this subdivision or verification of prepayment is a necessary part of a valid permit application or notice of coverage under a permit by rule.

(b) An annual fee of $260.00 for a permit related solely to a stormwater discharge associated with industrial activity or from a commercial site for which the department determines a permit is needed.

(c) Except as provided in subdivision (d), (e), or (f), an annual fee of $500.00 for a permit for a municipal separate storm sewer system.

(d) For a permit for a municipal separate storm sewer system issued to a city, village, or township, an annual fee determined by its population in an urbanized area as defined by the United States Census Bureau and, except as provided in subsection (11), based on the latest available decennial census, as follows:

( i ) For a population of 1,000 people or fewer, $500.00.

( ii ) For a population of more than 1,000 people, but fewer than 3,001 people, $1,000.00.

( iii ) For a population of more than 3,000 people, but fewer than 10,001 people, $2,000.00.

( iv ) For a population of more than 10,000 people, but fewer than 30,001 people, $3,000.00.

( v ) For a population of more than 30,000 people, but fewer than 50,001 people, $4,000.00.

( vi ) For a population of more than 50,000 people, but fewer than 75,001 people, $5,000.00.

( vii ) For a population of more than 75,000 people, but fewer than 100,001 people, $6,000.00.

( viii ) For a population of more than 100,000 people, $7,000.00.

(e) An annual fee of $3,000.00 for a permit for a municipal separate storm sewer system issued to a county.

(f) For a single municipal separate storm sewer systems permit authorizing a state or federal agency to operate municipal separate storm sewer systems in multiple locations statewide, an annual fee determined in accordance with a memorandum of understanding between that state or federal agency and the department and based on the projected costs of the department to administer the permit.

(2) A stormwater discharge permit is not required for a municipality that does not own or operate a separate storm sewer system. The department shall not collect stormwater discharge fees under this section from a municipality that does not own or operate a separate storm sewer system.

(3) Permit fees required under this section are nonrefundable.

(4) A person that possesses a permit not related solely to a site of construction activity as of January 1 shall be assessed a fee. The department shall notify those persons of the fee assessments by February 1. Payment must be postmarked no later than March 15. Failure by the department to send a person a fee assessment notification by the deadline, or failure of a person to receive a fee assessment notification, does not relieve that person of the obligation to pay the fee. If the department does not meet the February deadline for sending the fee assessment, the fee assessment is due not later than 45 days after the permittee receives a fee notification.

(5) If a stormwater permit is issued for a drainage district, the drainage district is responsible for the applicable fee under this section.

(6) The department shall assess interest on all fee payments submitted under this section after the due date. The permittee shall pay an additional amount equal to 0.75% of the payment due for each month or portion of a month the payment remains past due.

(7) The department shall forward fees and interest payments collected under this section to the state treasurer for deposit into the fund.

(8) The department shall require the payment of the fee assessed under this section as a condition of issuance or reissuance of a permit not related solely to a site of construction activity.

(9) In addition to any other penalty provided in this part, if a person fails to pay the fee required under this section by the due date, the person is in violation of this part and the department may undertake enforcement actions as authorized under this part.

(10) The attorney general may bring an action to collect overdue fees and interest payments imposed under this section.

(11) If the permit is for a municipal separate storm sewer system and the population served by that system is different than that determined by the latest decennial census, the permittee may appeal the annual fee determination and submit written verification of actual population served by the municipal separate storm sewer system.

(12) A person that wishes to appeal either a fee or a penalty assessed under this section is limited to an administrative appeal under section 631 of the revised judicature act of 1961, 1961 PA 236, MCL 600.631. The appeal must be filed not later than 30 days after the department's fee notification under subsection (4).

Municipal separate storm sewer system includes systems similar to separate storm sewer systems in municipalities, such as systems at military bases, large hospital or prison complexes, and highways and other thoroughfares. Municipal separate storm sewer system does not include separate storm sewers in very discrete areas, such as individual buildings.
