PAH Reduction through Phase-Out of Coal Tar-Based Pavement Sealcoats
The Minnesota Pollution Control Agency (MPCA) is engaged in a project funded by U.S. EPA’s Great Lakes Restoration Initiative through 2014 to promote phase-out of coal tar-based pavement sealcoat (CTS) in order to reduce environmental loading of polycyclic aromatic hydrocarbons (PAHs).
Audiences of the project are throughout the sealcoat supply chain, including those making, selling, applying, purchasing, consulting, regulating product use, and managing stormwater run-off. Tools and strategies used in Minnesota will be disseminated to partners in the Great Lakes Basin and beyond. See the project's portal web page at http://www.pca.state.mn.us/h8udqd6.
Interested states, provinces, municipalities or organizations should contact the Project Manager (at left).
- COMPANY PLEDGE - Contractors and Suppliers: If you have already stopped using or selling coal tar sealcoat, or will commit to not doing so anywhere going forward from a specific date, please consider signing and returning the company pledge commitment form HERE.
WISCONSIN MATERIALS - Developed by project partner University of Wisconsin Solid and Hazardous Waste Education Center.SCREENING TEST - Low-cost screening test for coal tar content.FALL 2013 WEBINAR MATERIALS - Presentations and recordings from the series.PROJECT SUPPORT - Request for Proposal and Contract files for grant contract to conduct coal tar sealcoat PAH reduction work in Great Lakes states or provinces outside Minnesota. MPCA executed a contract for this purpose with Freshwater Future, effective March 10, 2014. See http://www.freshwaterfuture.org/ for more information.
This is a voluntary commitment, but once it is made, we expect companies to honor it or notify us if they go back to coal tar. On behalf of the project, the MPCA is hosting and maintaining on its website an interactive map and lists of companies committed not to use or sell coal tar sealcoats (see http://www.pca.state.mn.us/uu4yx6y).
