The City of Newport, Minnesota (population 3,435) became the 20th community in Minnesota to pass a ban of coal tar sealers. Last week’s passage of the ban was confirmed earlier today by Renee Helm, the Executive Analyst for Newport. The community is just a 15 minute drive to Minneapolis and is primarily residential.

The City is yet another suburban Minneapolis-St. Paul area community that has found it is better to stop the expensive contamination of area ponds by eliminating this product. The cost of the cleanup of these ponds has been estimated by the State of Minnesota to be more than a billion dollars.

Kudos to State Representative Bev Scalze who had the insight to create funding for a portion of the costs to clean up these ponds in Minnesota and to the staff at the Minnesota Pollution Control Agency (MPCA) for their insight on how to further the work of the USGS with a Minnesota context.

ARE YOU SAFE?]]> http://topsealers.com/blog1/?p=18 2012-04-30T21:50:33Z 2012-04-30T21:50:33Z There are many reasons you need to warn others the dangers of coal tar asphalt sealant. If where you live is not on the list below then you need to know the dangers of the exposure to coal tar sealant.

Coal tar is a liquid used as a protective sealant for pavement around the nation. This type of sealant made with coal tar is widespread, and marketed as a means for keeping parking lot pavement in good condition for a longer period of time. However, a new study by the U.S. Geological Survey (USGS) provides substantial evidence that these sealants emit highly toxic contaminants, known as aromatic hydrocarbons (PAHs), into the atmosphere at higher rates than vehicular emissions.

Coal tar sealant, which is comprised of 50% PAHs, can be found on many parking lots, playgrounds, and driveways around the United States. Sealant made with coal tar is found disproportionately in central and eastern America—85 million gallons of coal tar is used each year. Why should we be so concerned? Put simply, PAHs can cause cancer and a host of growth and development abnormalities and deformities, making children’s exposure to the contaminant especially troubling.

These contaminants are finding ways indoors as well as outdoors. For a while now, scientists have believed PAHs through food consumption to be the primary method by which children are exposed. However, further studies by Baylor University and the USGS maintain that children living in close proximity to pavement sealed with coal tar are exposed to twice the amount of PAHs through ingestion of contaminated dust than from food. Ingestion of contaminated dust particles by children living near coal-tar-sealed pavement is 14 times higher than children living near unsealed pavement.

Such widespread use of coal tar is unnecessary because there are suitable alternatives. Asphalt-based sealant is used mostly on the west coast of the United States, and is a viable alternative. Asphalt-based products have 1/1000th of the PAH levels that coal products have. Furthermore, the Environmental Protection Agency (EPA) conducted studies of its own concerning run-off from coal tar. One study, the Assessment of Water Quality of Runoff from Sealed Asphalt Surfaces, found runoff from coal tar based sealant to be exponentially more potent in PAHs than asphalt based sealant. The EPA concluded that banning coal tar altogether might be the most cost effective way to combat the pollution problems caused by the sealant in the long run.

To date, a number of state governments have banned the use of coal tar sealant. Coal tar based sealant is also banned in the European Union. It would seem that a national ban on such a noxious substance is the next logical step. Please sign below to urge the EPA to adopt a safe nationwide policy.

How much? Over 800% higher!

Basically the report seeks to update our understanding of the carcinogenic potential of polycyclic aromatic hydrocarbon (PAH) mixtures like coal tar sealants and other solutions (oils, products, smoke, etc.). The EPA sent it out for a draft review in Feb 2010. In March 2011 a review by leading non-EPA scientists was completed on the validity of the findings. In general they found the assumptions and approach adequate, but asked for more research. How or if EPA will address these recommendations is unclear.

The EPA recommends the addition of 18 more PAH chemicals to the relative potency factor (RPF) calculation. Some of these chemicals are not widely tested for and it is difficult to say the impact on the RPF, but there is enough information to estimate a minimum potential increase. Contrary to what the sealant industry has said in public, these factors are going up. The EPA scientists find that PAH mixtures are more toxic than was believed to be when they were proposed in 1993.

My calculations indicate the RPF for an average coal tar sealant will increase at a minimum over 800% over current potency estimations with the real chance of going higher with additional information! That’s big. How would this affect human health and sealants? They maybe more likely to cause cancer than was previously estimated, but there are additional questions that the independent scientists asked the EPA that may affect the cancer potential of specific exposure types.

Here in the mid west we could start sealing as early as April. This year however, we are starting a little later because of our weather conditions. In order to get the optimum performance from your seal coating you MUST wait until the temperature outside is at least 50 degrees for 24 hours after application.

NO manufacturers of sealer will not honor any warranty if these conditions have not been met. West Suburban Asphalt stands behind ALL of their work. Call to ask about our guarantees we offer.
