AB 1099: Relating to: moratorium on data centers.

This bill establishes a moratorium on operating new data centers in the state unless specific conditions are met, directly affecting companies that build or operate large-scale digital storage and processing facilities. It requires the creation of a statewide planning authority and mandates that data centers cannot shift their energy or water costs to residential customers. The legislation also includes requirements for mandatory public reporting of resource usage, environmental safeguards, 100% renewable energy from newly built projects, prevailing wage standards for construction workers, and prior approval by local voters before a data center can be built. Additionally, it prohibits financial subsidies for data centers, bans nondisclosure agreements between data centers and local officials, and restores public utility planning authority.

AB 1151: Relating to: securitization of retiring power plants. (FE)

This bill amends Wisconsin statutes to clarify how retiring power plants fueled by nonrenewable energy sources are classified for environmental control cost calculations. It explicitly includes the unrecovered value of retired property and associated demolition costs when utilities determine financial obligations for environmental compliance. The changes apply to energy utilities managing facilities that use nonrenewable combustible energy resources and aim to ensure these costs are properly accounted for in regulatory asset valuations. The legislation does not mandate retirement of any plants but adjusts how existing financial reporting rules treat decommissioning expenses.

SB 1120: Relating to: securitization of retiring power plants. (FE)

This bill would update state statutes to clarify how retiring power plants fueled by nonrenewable energy sources are classified for environmental cost calculations. It defines the retirement of such facilities as a specific category of environmental control activity and expands the definition of environmental control costs to include the unrecovered value of retired property and related demolition expenses. The changes apply to energy utilities managing the decommissioning of existing power plants and aim to ensure these costs are properly accounted for in regulatory assessments.

This bill would ban the sale of products containing intentionally added PFAS chemicals starting in 2032, covering items like food packaging, cookware, cosmetics, and textiles used in homes. It requires manufacturers to submit detailed information about PFAS use in their products and allows the state to add more product categories to the ban through future rules. A complete ban on all intentionally added PFAS would take effect in 2038, except for uses deemed necessary for public safety or the environment. The law includes exemptions for medical devices, firefighting foam, and products governed by federal law, with a penalty of $100 per violating product per day for noncompliance.

The program would be managed by a nonprofit organization under the oversight of a new board that includes state officials, legislators, and representatives from conservation and youth training groups. Key provisions require that at least 50% of workers come from underserved populations, pay workers a minimum of $15 per hour, provide health insurance equivalent to a gold-level plan, and offer weekly housing stipends or accommodations.

The law also prevents the sale of cosmetics containing ingredients tested on animals after the deadline, with limited exceptions for testing required by federal or state regulations, foreign jurisdictions, or specific federal laws. Penalties for violations include a $5,000 forfeiture plus $1,000 for each day the violation continues. This legislation directly affects cosmetic manufacturers, importers, and sellers operating in the state by establishing clear restrictions on animal testing practices and product sourcing.
