This project supports reduction or phase-out of the use of coal tar-based sealcoats for asphalt pavement surfaces. Such actions will reduce loading of polycyclic aromatic hydrocarbons (PAHs) to surface waters and sediments in Great Lakes states and provinces, and reduce hazards to children and vulnerable adults playing, living or working near coal tar-sealed surfaces like drives, parking lots, and playgrounds.
This project was funded by a Great Lakes Restoration Initiative grant from the U.S. Environmental Protection Agency and was led by the Minnesota Pollution Control Agency (MPCA). Partners included Freshwater Future, the Michigan Department of Environmental Quality, the University of Wisconsin-Extension Solid and Hazardous Waste Education Center and the Great Lakes Regional Pollution Prevention Roundtable.
For more background or technical assistance, contact Al Innes, MPCA, firstname.lastname@example.org, 651-757-2457.
The following document lists some who have phased out coal tar sealcoats.

The University of Wisconsin-Extension Solid and Hazardous Waste Education Center (SHWEC) has created an educational series on asphalt sealcoats, to help guide Wisconsin citizens and communities on choosing safer asphalt sealcoats:
- Wisconsin: Coal-tar-based asphalt sealcoats - A health and environmental hazard
- Wisconsin: Keeping coal tar out of school yards - A guide for Wisconsin’s school districts
- Wisconsin: Avoiding high costs from stormwater sediment contaminated by coal-tar-based asphalt sealcoats
- Wisconsin: Avoiding coal-tar-based asphalt sealcoats and finding a coal-tar-free sealcoat applicator
- Wisconsin: Choosing a coal-tar-free sealcoat - Guidance for property owners and managers
All presentations and recordings from the Fall 2013 webinar series are available for viewing.
