Commercial Agricultural Operations

Commercial Agricultural Operations

The California Air Resources Board (CARB) has adopted the most health-protective Ambient Air Quality Standards (CAAQS) for PM10 (respirable particulate matter with an aerodynamic diameter of 10 micrometers or less) in the nation.  The PM10 standards in California are 20 µg/m3 (measured as an annual mean) and 50 µg/m3 (measured as a daily concentration).  Virtually the entire State is nonattainment for the PM10 standards; this includes Eastern Kern County.

Activities associated with Agricultural (AG) Operations have been identified as a significant source of PM10 emissions (fugitive dust) that can contribute to poor air quality in some regions of Eastern Kern.  The District recognizes a majority of the fugitive dust generated from AG Operations can easily be mitigated. 

On March 12, 2015, the District’s Board adopted Rule 402.2 (Agricultural Operations), which is designed to prevent, reduce, and mitigate ambient concentrations of anthropogenic fugitive dust emissions generated from agricultural operations through implementation of Conservation Management Practices.
