Public utilities: rates; separate rate class for large-load customers; require. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10ii.

Maddy summarySB 1047 creates a new rate class for large energy users, specifically targeting data centers, to ensure they do not shift costs to residential and small business customers. The bill requires these facilities to sign long-term contracts with electric utilities that include a minimum monthly charge based on their potential usage, even if they consume less power. Additionally, the legislation mandates that large energy users pay for all costs they cause, such as new power lines and generation, and must provide collateral or a letter of credit to guarantee these payments. To further protect the grid, the bill also requires these facilities to participate in demand response programs, source 90% of their electricity from clean energy, and pay a significant application fee.

Water supply: conservation; permit for water used for consumptive use purposes; provide for. Amends secs. 32705, 32708a, 32713 & 32723 of 1994 PA 451 (MCL 324.32705 et seq.) & adds sec. 32723a.

Maddy summaryThis bill updates Michigan's water laws to streamline the registration process for large-scale water withdrawals while introducing new requirements for water conservation and reporting. It primarily affects property owners, agricultural operators, and industrial facilities that plan to extract significant amounts of water, requiring them to register their intended capacity before beginning operations. The legislation mandates that the state develop and post generic water conservation measures for different sectors, with specific rules for agriculture and data centers, and requires facilities permitted under new provisions to submit annual reports on wastewater usage and pollutant levels. Additionally, the bill clarifies exemptions for smaller residential wells and test wells, while establishing a timeline for property owners to develop their water capacity after registration or face invalidation of their application.

Public utilities: electric utilities; project labor agreements and prevailing wage and fringe benefit rates; require for certain data center contracts. Amends 1939 PA 3 (MCL 460.1 - 460.11) by adding sec. 10ii.

Maddy summaryThis bill requires electric utilities in Michigan to include specific labor conditions in contracts for building or maintaining data centers. Under the new rules, these projects must use registered apprenticeship programs, pay workers at least the prevailing local wage and fringe benefit rates, and utilize project labor agreements or collective bargaining agreements. The legislation defines data centers as facilities housing equipment for data storage and processing and aims to ensure fair labor standards for construction work without speculating on future economic impacts.

Public employees and officers: other; certain nondisclosure agreements; prohibit. Creates new act.

Maddy summaryThis bill, known as the Data Center Nondisclosure Agreement Prohibition Act, prevents public employees and officers in Michigan from signing nondisclosure agreements related to data center projects. It defines a data center as a facility with significant power demand and restricts these officials from using confidentiality claims to hide information from the public. The law applies to agreements entered into, amended, or renewed after its effective date, though it allows exceptions for legally privileged information or settlement documents. Violations of this rule could result in a civil fine of up to $1,000, which can be pursued by county prosecutors or the attorney general.

Education: teachers and administrators; interim teaching certification process; modify. Amends sec. 1531i of 1976 PA 451 (MCL 380.1531i).

Maddy summaryThis bill modifies Michigan's interim teaching certification process to establish stricter requirements for individuals seeking to teach without a full teaching certificate. It mandates that all candidates complete an approved alternative program with intensive training equivalent to at least 12 college credits, including coursework in child development, diverse learners, and classroom experience. A significant change is the prohibition of new interim certificates for special education teaching starting July 21, 2027, which requires applicants to complete an additional 32-credit specialized training program unless they already hold a full teaching certificate. The legislation also ensures that teachers holding these interim certificates receive intensive observation and coaching while they work toward earning a permanent Michigan teaching certificate.

State finance: authorities; use of grant funds and issuance of revenue bonds; modify. Amends title & secs. 2, 8, 9, 10, 13, 14, 14a, 16, 18, 20, 23, 24 & 25 of 1978 PA 639 (MCL 120.102 et seq.) & adds sec. 19a.

Maddy summarySB 52 amends Michigan's Port Authority Act (1978 PA 639) to update financial rules for port authorities. It modifies how these authorities manage grant funds, issue revenue bonds, and use "ancillary financing facilities" like interest rate swaps or insurance contracts. The bill adds new language (Section 19a) and revises multiple existing sections to clarify financial operations. This procedural update directly affects port authorities managing state-owned port facilities, such as piers, docks, and related infrastructure, without creating new facilities or changing their core responsibilities.

Vehicles: fund-raising registration plates; fund-raising registration plate for spay and neuter clinics; create. Amends 1949 PA 300 (MCL 257.1 - 257.923) by adding sec. 811kk.

Maddy summarySB 106 creates a special vehicle registration plate in Michigan that supports animal welfare. Vehicle owners who purchase this plate will contribute funds to a dedicated "Protecting Michigan's Pets Fund," managed by the state treasurer. The fund receives all plate sale proceeds and disburses money quarterly to the Michigan Pet Alliance to support spay/neuter programs and care for homeless/abused animals in shelters. This bill directly affects plate buyers and provides a new funding source for animal welfare organizations.

Animals: care and treatment; forfeiture of seized animals and restitution for the animals' care; amend. Amends sec. 50 of 1931 PA 328 (MCL 750.50).

Maddy summarySB 293 amends Michigan’s animal welfare law (MCL 750.50) to clarify and strengthen standards for animal care. It defines "adequate care" as providing food, water, shelter, and veterinary attention to maintain an animal’s health, and prohibits neglect that jeopardizes health. The bill requires owners to reimburse shelters for care costs when animals are forfeited due to neglect, and adds specific rules like tethering dogs with a minimum 3x length leash. It directly affects pet owners, breeders, pet shops, and animal shelters by imposing penalties for violations and creating restitution mechanisms. The changes focus on concrete standards for care, abandonment, and transportation, without adding new categories of prohibited conduct.

Crimes: animals; forfeiture of seized animals and restitution for care and treatment of certain forfeited animals; amend. Amends sec. 50b of 1931 PA 328 (MCL 750.50b).

Maddy summarySB 294 strengthens Michigan's animal cruelty laws by increasing penalties for harming companion animals (like pets and service animals) and adding new requirements for convicted individuals. It classifies offenses into three degrees (with first-degree punishable by up to 10 years in prison) and mandates courts to order restitution for animal care costs, including veterinary treatment and shelter. The bill also allows courts to prohibit convicted individuals from owning animals for a specified period or permanently. Exemptions cover lawful activities like hunting, farming, and veterinary care. This law directly affects people convicted of animal cruelty, particularly those targeting companion animals.

Primary SB 604

Liquor: authorized distribution agents; authorized distribution agent fees; increase. Amends sec. 205 of 1998 PA 58 (MCL 436.1205).

Maddy summarySB 604 allows authorized liquor distribution agents in Michigan to charge up to $20 for special emergency orders of spirits to retail stores, which must be delivered within 18 hours (or by Monday noon if ordered on weekends). This directly affects retailers needing urgent stock and distribution agents who can now impose this fee for emergency deliveries outside regular weekly schedules. The bill amends existing rules to establish this fee limit while maintaining other requirements for distribution, such as weekly delivery schedules and reporting obligations for emergency orders.
