Gap View Board: Explore alternatives to coal tar and delay Aug 6 pavement project
This petition made change with 67 supporters!
I am concerned about the documented health risks associated with using Paverx in our neighborhood. Tell the board to delay this project until there is more discussion about the risks and alternatives.
Gap View Village residents received a letter Friday, July 27 informing us that our board will begin treating our roads with a product called Paverx, a coal tar based sealant, starting Monday, August, 6.
Coal tar sealants contain a toxic group of chemicals known as PAHs (Polycyclic Aromatic Hydrocarbons). PAHs have been classified as carcinogenic, mutagenic, and reprotoxic by:
- The U.S. Department of Health and Human Services (HHS)
- The International Agency for Cancer Research (IACR)
- The Center for Disease Control (CDC, Agency for Toxic Substances and Disease Registry).
The American Medical Association since 2016, urges legislation banning coal tar sealants.
Coal tar sealants are outright banned in Minnesota, Connecticut, and Washington.
Coal tar sealants have been banned or restricted locally in Washington DC, Wisconsin, Massachusetts, Maryland, Texas, Illinois, New York, Michigan, South Carolina, North Carolina, Kansas, California, and Missouri.
Major retail outlets that have banned coal tar sealants since 2011 include Home Depot, Lowe’s, and Ace Hardware.

Serious Health Risks
This isn’t just something that is applied outdoors and remains outside. Studies show the carcinogenic dust continues to enter your homes for up to 8 years and your family and pets will be consuming and breathing this. Children are at especially high risk.
- Living adjacent to coal-tar-sealed pavement (a parking lot or driveway, for example) is estimated to increase excess lifetime cancer risk 38 times, and much of the increased risk occurs during early childhood. 50% of the increased risk is to children under age 6, and 80% of the increased risk to children under 18. (Baylor University, 2012)
- Children under age 6 with daily exposure of 1,000 PHCs for 1 year are at increased risk for reduced lung function, abnormal chest x-rays, bloody vomit, and chest irritations. (CDC Toxology Profile)
- Children living in homes adjacent to pavement with coal-tar-based sealcoat were likely exposed to about 14-fold higher doses of PAHs than those living adjacent to unsealed pavement. (Univ New Hampshire, 2012)
- Coal-Tar-Based Parking Lot Sealcoat: An Unrecognized Source of PAH to Settled House Dust (USGS, 2010)
- Health risk to Children from toxic pavement sealant greater than previously believed. Children living by coal tar-sealed parking lots and driveways are getting a bigger dose of PAHs from house dust than from their food. (Baylor University, 2012)
There are at least 17 alternate asphalt based sealants that contain no or low amounts of PAHs. Coal tar sealants contain 50,000–70,000 PAHs. The common regulatory limit is 1,000 PAHs.
With multiple alternatives and the information available about the risks associated with coal tar sealants and PAHs, there is absolutely no reason why we should be applying something in our neighborhood that our children will walk and play on, our pets will walk on, and will be tracked into our homes and be consumed on a daily basis for years to come.
