Agricultural Dust Program

Agricultural Dust Program compliance officers:   

  • Educate agricultural operations on dust impacts and measures to reduce dust 
  • Inspect agricultural operations for use of best management practices (Ag BMPs) 
  • Respond to public agricultural dust complaints and monitor exceedances of particulate matter 10 (PM10)  

What are Agricultural Best Management Practices (Ag BMP)? 

Per Arizona Administrative Code, Ag BMP is a technique, verified by scientific research, that is practical, economically feasible and effective in reducing PM emissions from a regulated agricultural activity. In 1981 the AG BMP commitee was formed | Learn More > 

Who must follow agricultural dust rules? 

The state of Arizona has general rules that require all agricultural operations across the state to take reasonable precautions to minimize dust emissions. Operations in areas that do not meet federal air quality standards (PM10 non-attainment areas) are required to abide by more specific requirements in the Ag BMP rules. 

Under the these rules, an Ag BMP Permit record is required for an agricultural operation or Concentrated Animal Feeding Operation (CAFO) if it is greater than 10 adjoining acres in size and/or meets animal number thresholds and is in a PM10 non-attainment area. This permit is intended to reduce dust from these operations by requiring operators to implement Ag BMPs. The Ag BMP Permit Record must be kept up to date by the operator and made available to ADEQ within two business days of notice to the operator.
