The City of Austin amended its Code to ban the use and sale of pavement sealants containing coal tar within the City’s planning jurisdiction (full purpose city limits and ETJ). The one exception is that the sealant may be sold if the intended application area is outside the City’s ETJ. The Austin ban was effective January 1, 2006.
PAHs are a high-profile pollutant of growing concern nationwide, due to increasing concentrations in waterways
City research has found that coal tar-based sealants are a major source of PAHs; a ban provides an unprecedented opportunity to eliminate a significant pollutant threat to our local water resources
The combination of chemical tracing, laboratory toxicity, and field-verified degradation provides ample evidence to support regulatory action to remove the use of coal tar sealants within the City’s jurisdiction
