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 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. Links to efforts to date are available below.

This web page is the portal to a variety of materials useful as background and for outreach to audiences in your community. These materials are currently specific to Minnesota but are available to other interested state, provincial, or local organizations to adapt to their own needs. You get to them through the following pages, which are grouped by target audience or supporting topics, and are also linked from the Minnesota page above.

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.
