Management Coal Tar Pavement Products
Bill 21-12, Erosion, Sediment Control and Stormwater Management
Coal Tar Pavement
Products, sponsored by Councilmembers Rice, Navarro, EIrich, Riemer, and Ervin, was
introduced on June 19, 2012. A public hearing was held on July 17, at which speakers testified
in support and opposition to Bill 21-12 (see select written correspondence at ©39-54).
Bill 21-12 would prohibit the use and sale of coal tar pavement products in the County and
require enforcement by the Department of Environmental Protection. Attached on © 10 is a
recent study describing the problems caused by polycyclic aromatic hydrocarbons (PAH's)
released into the environment through the use of a coal tar pavement product. Coal tar and coal
tar pitch are Group 1 carcinogens and the Environmental Protection Agency classifies 7 PAH
compounds as probable human carcinogens.
What are coal tar, coal tar sealants, and polycyclic aromatic hydrocarbons (PAH)? Coal tar
a byproduct of the coking of coal for the steel industry and coal-tar pitch is the residue that
remains after the distillation of coal tar. Coal-tar pitch is at least 50% PAH's by weight and is
known to cause cancer in humans.
is a liquid that is sprayed or painted on some asphalt pavement to protect the
pavement surface. Sealcoat products generally have a coal-tar-pitch or asphalt base. Coal-tar
based sealcoat products are usually 20-35% coal-tar pitch and have about 1,000 times more
PAH' s than sealcoat products with an asphalt base.
Polycyclic aromatic hydrocarbons (PAH's)
are a group of chemical compounds that form when
anything with a carbon base is burned (e.g., wood, gasoline, cigarettes, meat). PAH's are also in
