**Coal Tar Sealers Strictly Prohibited**
A Commercial Sealant Applicators Annual Permit and License Required For Work Within West Bloomfield
In March of 2017, the Environmental Commission along with the Township Supervisor was alerted to the public and environmental health hazards associated with the widespread use of coal tar sealants. The Township drafted a Coal Tar Sealant Ordinance to protect the residents and the environment of West Bloomfield Township.
Coal tar based sealant products are commonly applied to parking lots and driveways to improve aesthetics and to increase longevity of the asphalt paved surfaces. These sealants typically consist of 20−35% coal tar pitch. Coal tar sealants contain polycyclic aromatic hydrocarbons (PAHs), which are identified as toxic, mutagenic, teratogenic (causing birth defects), and/or probable human carcinogens.
PAHs from coal tar sealants are released into the environment through volatilization into the air and as dust when the sealant breaks up over time. The dust particles affix to sediments as they are moved toward lakes, streams, wetlands and storm basins during rain events. Studies conducted by the Minnesota Pollution Control Agency, the U.S. Geological Survey (USGS), and the University of New Hampshire Stormwater Center have concluded that coal tar based sealants are an important source of PAHs to suburban waterways. Also, studies show 50-75% of all PAHs found in sediments within the Great Lakes region come from coal tar sealants.
The ordinance is structured similarly to our fertilizer control ordinance, whereby the township will require commercial applicators to obtain a license prior to operating in the township. The ordinance strictly prohibits the use of coal-tar sealants by commercial applicators as well as by residential and commercial property owners. It is important to note that alternative asphalt sealant products exist at similar prices.
The ordinance license procedure and enforcement will commence in 2018 and will be accompanied by a public education campaign. A fee schedule for the ordinance is forthcoming.

Choose Sealant Applicators that will provide you with sealants that meet the ordinance. Each licensed Sealant Applicator will have an orange sticker prominently displayed on their vehicle for easy identification.
