AB 130 exempts specific groups from certain PFAS enforcement actions under Wisconsin's spills law if they allow the state to clean up contaminated land at no cost to them. It directly affects landowners, fire departments, airports, wastewater spreaders, and waste facilities that handled PFAS-contaminated materials legally. The bill creates exemptions for those who spread permitted biosolids, owned land where such spreading occurred, used PFAS in emergency response (per federal rules), accepted PFAS waste, or own property not responsible for the contamination origin. This applies only to enforcement sections related to PFAS contamination under the spills law, not all PFAS regulations.

AB 453 requires counties and cities to include specific elements in their comprehensive land-use plans, such as 20-year projections of residential development (in 5-year increments) and maps showing current/future land uses, including environmentally sensitive areas. It mandates that local ordinances related to residential development must align with these plans, though density requirements (specifying minimum/maximum residential units per acre) apply only to cities, not towns or counties. The bill affects local governments by standardizing planning processes for residential growth and ensuring consistency between zoning rules and long-term land-use goals. It does not create new taxes or funding but updates existing planning statute requirements.

AB 619 creates a $150 million grant program to fund aviation biofuel manufacturing projects in Wisconsin, funded through state public debt issuance. The bill requires grantees to use facilities exclusively for aviation biofuel production (with limited exceptions for other biofuels if 80% of output is aviation fuel), source 80% of biomass locally, and invest at least $1.5 billion in aviation biofuel manufacturing within five years. It directly affects companies building such facilities and the Department of Natural Resources, which administers the grants. The program aims to support the state's forest products industry and create jobs, with strict repayment terms if grantees fail to meet requirements.

SB 323 establishes a state program providing no-interest loans to eligible dairy farms for specific upgrades. It directly affects dairy operations with 50-714 cows that meet strict criteria, including 98% in-state workforce, no recent environmental or safety violations, and legal employment compliance. Loans can fund technologies to improve milk production efficiency, animal health, milk quality, or reduce environmental impacts from manure management. The program prioritizes applicants creating new skilled jobs or reducing environmental effects per gallon of milk produced. The bill creates a formal process for applications and administration through the state corporation, with a fiscal estimate received as of July 2025.

SJR 7 is a non-binding legislative resolution passed by Wisconsin's legislature declaring support for nuclear power and fusion energy as critical clean energy sources. It states the legislature's commitment to advancing these technologies, citing their role in providing 66.6% of Wisconsin's carbon-free electricity, powering 1.2 million homes, and supporting 650 high-paying jobs. The resolution does not create new laws or allocate funds but formally recognizes nuclear/fusion energy as essential for meeting energy demands and reducing emissions. It emphasizes Wisconsin's existing nuclear infrastructure (including two operating reactors) and academic resources as foundations for future growth in this sector.
