Great Basin Unified Air Pollution Control District Agricultural Operations Conservation Management Practices for Farms in Inyo, Mono and Alpine Counties The very nature of producing food and fiber crops generates dust and small particulate matter, commonly referred to as PM10 (Particulate Matter with an average size of 10 microns or less - about one-seventh the diameter of a human hair). For many years farmers have worked to reduce the amount of dust generated from agricultural practices as a means of preserving topsoil, controlling certain dust-loving pest populations and maintaining good neighbor relations. In California, over the last few years attention has been focused on reducing dust and PM10 emissions from on-farm activities as part of the effort to help improve the state's air quality. Many areas of the state will never attain the federal or state PM10 standards unless agricultural activities implement additional dust control measures. In addition, as more land is developed next to and within agricultural areas, dust that in the past did not impact people in their homes or at their jobs, is now having a direct impact on people's health. In 2004, the state passed a law known as SB 700 that makes agricultural operations subject to the same air pollution requirements as other commercial and industrial operations and requires farm activities to implement additional measures to control air pollution. The Great Basin Unified Air Pollution Control District (serving all of Alpine, Inyo and Mono Counties) has adopted rules to control dust emissions from agricultural practices in an effort to attain and maintain the federal and state standards for PM10. The rules, Rule 502 (Conservation Management Practices) and Rule 307 (Conservation Management Practices Plan Fee), require farmers to implement and document an annual plan to reduce dust and PM10 emissions from on-farm sources, such as from unpaved roads and equipment yards, during land preparation, harvest activities and from other cultural practices. These plans are known as Conservation Management Practices (CMP) Plans. In order to recover the cost of plan processing and field inspections, the Air District will collect fees from those farms that must comply with the CMP requirement. What is Required?
