Great Lakes Coal Tar Sealcoat PAH Reduction Project
This project supports phase out of the use of coal tar-based sealcoats for asphalt pavement surfaces.
The document below lists who has phased out coal tar sealcoats.
The Minnesota Pollution Control Agency (MPCA) leads the project, and is collaborating with the Michigan Department of Environmental Quality, the University of Wisconsin-Extension Solid and Hazardous Waste Education Center, the Great Lakes Regional Pollution Prevention Roundtable, and the U.S. Environmental Protection Agency. For more information about this project, contact Al Innes, MPCA, firstname.lastname@example.org, 651-757-2457.
Links to past and future efforts are available below.
- Revised Fall 2013 webinar series, all from 9:30-10:30 AM Central time:
- Interactive map of companies certifying they will not apply coal tar sealcoat.
- Company pledge/certification form
- More Minnesota information
- Wisconsin information
Originated in the Great Lakes area by a U.S. EPA Great Lakes Restoration Initiative grant, the project and its materials are open to anyone interested. (Map credit: Nations Online Project)
Phase-out and replacement of coal tar-based sealcoats with safer alternatives and practices 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.
As project partners develop resources, this web page will link to a variety of materials useful as background and for outreach to audiences in your community.
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:
- Coal Tar-Based Asphalt Sealcoats – A Health and Environmental Hazard
- Keeping Coal Tar Out of School Yards
- Avoiding High Costs from Stormwater Sediment Contaminated by Coal Tar-Based Sealcoats
- Avoiding Coal Tar-Based Asphalt Sealcoats
- Choosing a Coal Tar-Free Sealcoat
