The bill proposes the addition of Chapter 47.5 to Title 31 of the General Laws, titled "Environmental Impact Study of Motor Vehicle Non-Exhaust Emissions." It mandates the Department of Transportation, in consultation with the Department of Environmental Management, to conduct an environmental impact study of non-exhaust emissions particles, including microplastics, brake wear, tire and road wear, clutch wear, and road dust resuspension. The departments are authorized to collaborate with an academic research institute as part of their study. The study is required to result in a written report to the General Assembly that includes recommendations for reducing the environmental impact of tire particle emissions.

Additionally, both the Department of Transportation and the Department of Environmental Management must publicly post their report on their websites no later than January 1, 2027. This act will take effect upon passage.
