Safer Sealing to Protect People and the Environment. HRWC is advocating for policy changes and educating residents to protect the watershed from toxic coal tar.
In Michigan, coal tar-based sealcoat is applied widely on driveways, parking lots, and even playgrounds. Sealcoat applicators and their customers say the product enhances the look of weathered asphalt surfaces and prolongs product life. However, coaltar sealcoat can pose significant risks to humans and aquatic life.
HRWC has met with several townships to advocate for ordinances that prohibit sealcoats containing coal tar. There are alternative products that are comparably priced. Many have done so. We are also working to get a statewide ban.
