The State of Washington Senate is currently considering a coal tar sealant ban. In February the ban passed the House of Representatives. Did you know that the main ingredient, coal tar is currently on a list of “dangerous wastes” under Washington State law? About a dozen of coal tar’s PAH constituents are already on the dangerous waste list as well. We know from research that coal tar sealants are the source of highest concentration and mobility of any other PAH emitting activity. So does it make sense to allow it to be spread at schools, hospitals, homes and parking lots?

The department may conduct or contract for the removal of dangerous wastes or hazardous substances where there has been or is a potential for discharge or release, regardless of quantity or concentration, which could pose a threat to public health or the environment.
This section applies when any dangerous waste or hazardous substance is intentionally or accidentally spilled or discharged into the environment (unless otherwise permitted) such that human health or the environment is threatened, regardless of the quantity of dangerous waste or hazardous substance.
