Fugitive dust is an air quality term used to describe an emission which does not pass through a stack. At the smelter in Trail, this is dust that escapes the smelter site from stockpiles, open handling of materials, buildings and vehicle traffic. Fugitive dust is not stack emissions. Fugitive dust is a source of lead (Pb) in airborne dust. 

Teck Trail Operations manages fugitive dust at the smelter mainly by investing in initiatives to reduce fugitive dust on roads, in open mix areas, and in buildings. Some examples include improved road cleaning and dust suppressant, installing a windfence as well as wheel washes. They also focus on monitoring and real-time behaviour changes within the operation. See additional FAQ for more on fugitive dust reduction efforts.
