Air Quality - Agricultural PM10 Best Management Practices 

How Does Agriculture Impact Air Quality?

The federal Clean Air Act requires that air pollutant emissions be controlled from all significant sources in areas that do not meet the national ambient Air quality standards. Air Quality regulation for agriculture requires farmers and nurserymen in certain parts of Maricopa, Pinal, and Yuma Counties to implement Best Management Practices to reduce particulate emissions from tilling and harvesting, fallow cropland and non cropland areas. 

How Do Best Management Practices Help?

An agricultural Best Management Practice (BMP) is a practical, economical and feasible technique to reduce particulate matter from regulated agricultural activities. A wide range of variation in soils and cropping systems requires that BMPs are addressed on a case by case basis and fitted to specific farms. The BMPs are based on principles that slow or control soil movement from both cropland and non-cropland. Flexible BMPs for controlling PM10 is an effective and common sense practice that improves local and regional air quality.
