  • Fugitive Dust

    Fugitive dust is particulate matter which becomes airborne, is not emitted from a stack or vent, and has the potential to adversely affect human health or the environment. High levels of dust particles often originate from agricultural, mining, construction and manufacturing activities. PDEQ protects air quality by regulating fugitive dust emissions and inspecting dust-producing activities and sites. The Fugitive Dust Activity Permit Program ensures that those involved in activities likely to generate dust are aware of fugitive dust regulations and requires them to provide information regarding the location and types of dust-generating activities.
