Fugitive Dust

Fugitive dust is particulate matter which becomes airborne and has the potential to adversely affect human health or the environment.  The most common forms of particulate matter are known as PM10 (particulate matter with a diameter of 10 microns or less) and PM2.5 (particulate matter with a diameter of 2.5 microns or less).  High levels of dust particles often originate from activities such as agricultural, mining, construction, and manufacturing.  PDEQ protects air quality by regulating fugitive dust emissions.  The Activity Permit Program ensures that individuals are aware of fugitive dust emissions regulations and requires them to provide information regarding the location and types of activities so the department can monitor compliance.
