Environmental protection: pollution prevention; coal tar sealant or other high-PAH sealant for pavement; prohibit use and sale. Amends 1994 PA 451 (MCL 324.101 - 324.90106) by adding pt. 149.

Michigan Senate Bill 710 (SB0710) aims to protect the environment by prohibiting the use and sale of coal tar sealants and other high-polycyclic aromatic hydrocarbon (PAH) sealants for pavement surfaces. These sealants, commonly applied to driveways, parking lots, and playgrounds, contain substances harmful to human health and the environment. The bill amends the Natural Resources and Environmental Protection Act by adding a new part (Part 149) specifically addressing coal tar products. Key provisions include:

- **Definition of Coal Tar Sealant**: A surface-applied product containing coal tar, coal tar pitch, or related substances with more than 0.1% PAHs by weight.

- **Prohibition on Application**: Individuals are prohibited from applying coal tar sealants or other high-PAH sealants on asphalt, concrete, or other pavement surfaces.

- **Prohibition on Sale**: The sale of coal tar sealants or other high-PAH sealants is prohibited, with certain exceptions.

The bill was introduced on November 13, 2025, by Senators Sue Shink, Stephanie Chang, Erika Geiss, and Rosemary Bayer, and referred to the Senate Committee on Energy and Environment. As of now, it remains in the committee stage. ([legiscan.com](https://legiscan.com/MI/text/SB0710/2025?utm_source=openai))

While there is no specific media coverage available for this bill, similar legislative efforts in other states have faced opposition from industry groups concerned about the economic impact on businesses that manufacture or apply these sealants. However, environmental organizations and public health advocates have generally supported such measures, emphasizing the need to reduce exposure to harmful chemicals and protect water quality.

Given the bipartisan sponsorship of the bill and its focus on environmental protection, it is likely to receive support from environmental groups and public health advocates. Opposition may come from industry stakeholders concerned about the economic implications of the ban.

Environmental organizations and public health advocates are likely to support Michigan Senate Bill 710, viewing it as a necessary step to protect water quality and public health by eliminating harmful chemicals from pavement sealants.

Industry groups may oppose Michigan Senate Bill 710, expressing concerns about the economic impact on businesses involved in the manufacture and application of coal tar and high-PAH sealants.
