Fugitive Dust Countywide

Definition: Particles lifted into the air caused by man-made and natural activities such as the movement of soil, vehicles, equipment, blasting, and wind.

Purpose: To reasonably regulate operations which periodically may cause fugitive dust emissions into the atmosphere within Pinal County.

There are many reasons, both environmental and health related, why you should control fugitive dust. Fugitive dust is made up of fine particles. When inhaled, fine particles can accumulate in the respiratory system causing various respiratory problems including persistent coughs, wheezing and physical discomfort. Additionally, breathing these fine particles can increase susceptibility to respiratory infections and can aggravate existing respiratory diseases such as asthma and chronic bronchitis. Even short-term exposure to dust can increase the severity of respiratory problems.

  • Do not allow motor vehicles, such as but not limited to all-terrain vehicles, trucks, cars, cycles, bikes, or buggies to drive over vacant lots, or urban or suburban open areas without taking reasonable precautions to keep the fugitive dust from becoming airborne.

  • Do not allow particulate matter from agricultural practices including but not limited to tilling of land and application of fertilizers to become airborne without taking reasonable precautions.

  • Do not disturb or remove soil or natural cover from any area without taking reasonable precautions to effectively prevent fugitive dust from becoming airborne.

  • Do not allow crushing, screening, handling or conveying of materials, or permit material to be stacked, piled or stored without taking reasonable precautions to prevent fugitive dust from becoming airborne.

  • Machinery used at storage piles will be operated with a minimum fall of material using spray bars and wetting agents, to prevent particulate matter from becoming airborne.

  • Do not allow the fugitive dust to become airborne during the transporting of materials. Earth and other material that is tracked out or transported by truck or earth moving equipment onto paved streets will be removed by whomever is responsible for such deposits.
