Great Lakes Coal Tar Sealcoat PAH Reduction Project

This project supports reduction or phase-out of the use of coal tar-based sealcoats for asphalt pavement surfaces.

All presentations and recordings from the Fall 2013 webinar series are now available for viewing.

  • 10/29/13 – Overview of issues
  • 11/20/13 – State/provincial-level programs
  • 12/12/13 – Local education and action


The document below lists who has phased out coal tar sealcoats.

The Minnesota Pollution Control Agency (MPCA) leads the project, and is collaborating with Freshwater Future, 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 Cheryl Kallio of Freshwater Future at or 231-571-5001, or Al Innes, MPCA,, 651-757-2457.

Links to past and future efforts are available below.

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.

Wisconsin information

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:
