Findings—Intent—2025 c 312: "The legislature finds that litter is a persistent challenge that sullies public spaces, damages natural habitats, and pollutes the environment. Improperly disposing of trash poses significant risks to public health, our environment, and the economy.
The legislature also finds that single-use plastic bags are one of the most commonly found items that litter state roads, beaches, and other public spaces. Plastic bag litter is known to harm animals, particularly aquatic species, and contributes to the proliferation of microplastics, which pose significant threats to human health. Encouraging the adoption of alternatives to plastic bags, such as reusable carryout bags, reduces plastic waste. While thicker plastic bags may be more durable and reusable, initial research has demonstrated that many customers may still use them as single-use bags, and consequently, thicker plastic bags contribute to more plastic waste.
The legislature also finds that when specifically tailored, penalties and fees act as effective deterrents to harmful behaviors, such as littering, and can lead to the adoption of more sustainable practices.
Therefore, the legislature intends to discourage littering and the proliferation of plastic waste by enhancing penalties for littering, delaying requirements relating to increasing the thickness of reusable plastic bags, and imposing new penalties for the sale of thicker plastic bags. The legislature also intends to direct the fees collected from the new penalties to the waste reduction, recycling, and litter control account to address the negative impacts of litter." [ 2025 c 312 s 1.]
Findings—2024 c 231: "(1) The legislature finds that, despite a modern waste disposal infrastructure, the occurrences of unlawful solid waste dumping are an increasing problem on open spaces such as privately and publicly owned forestlands. This irresponsible waste dumping, which often includes hazardous materials, asbestos, derelict boats, junk vehicles, appliances, furniture, and household garbage not only creates significant costs for the landowner, but also creates immediate, and sometimes lasting, environmental and habitat damage and degradation of recreational and aesthetic opportunities.
(2) The legislature further finds that the current enforcement system, which relies on the criminalization of illegal dumping, may not be the most effective, efficient, or just penalty system. Converting all but the most egregious illegal dumping from a criminal act to a civil infraction creates a system of deterrence and penalties that better reflects the magnitude of the act, avoids criminal records for individuals who may be unable to afford appropriate waste management options, and reduces the burden on local criminal justice systems and infrastructures." [ 2024 c 231 s 1.]
Findings—2003 c 337: "(1) The legislature finds that the littering of potentially dangerous products poses a greater danger to the public safety than other classes of litter. Broken glass, human waste, and other dangerous materials along roadways, within parking lots, and on pedestrian, bicycle, and recreation trails elevates the risk to public safety, such as vehicle tire punctures, and the risk to the community volunteers who spend their time gathering and properly disposing of the litter left behind by others. As such, the legislature finds that a higher penalty should be imposed on those who improperly dispose of potentially dangerous products, such as is imposed on those who improperly dispose of tobacco products.
(2) The legislature further finds that litter is a nuisance, and, in order to alleviate such a nuisance, counties must be provided statutory authority to declare what shall be a nuisance, to abate a nuisance, and to impose and collect fines upon parties who may create, cause, or commit a nuisance."
