The proposed bill, known as the "Stormwater Management Utility Act," aims to regulate the establishment of stormwater management utilities by local governments in Michigan. It outlines the creation of stormwater management plans, the adoption of utility fee ordinances, and the establishment and collection of stormwater management utility fees. The bill defines key terms such as "stormwater management system," "stormwater management utility," and "stormwater management utility fee," and mandates that local units of government adopt a stormwater management plan and utility fee ordinance to create a stormwater management utility. Additionally, it provides guidelines for public hearings, the calculation of fees, and the establishment of a stormwater enterprise fund to manage collected fees.

The bill also includes provisions for the reduction or elimination of stormwater management utility fees based on property modifications that reduce runoff or pollutant loadings. It establishes an appeals process for property owners disputing the fees, requiring them to demonstrate their case based on the stormwater management plan. Furthermore, the bill clarifies that it does not repeal existing laws or limit the powers of local governments, and it specifies that the act applies only to utilities created after its effective date, which is set for 90 days post-enactment.
