The plan, specifically for particulate matter measuring 10 microns or less in size (PM10), includes measures set forth by both the San Joaquin Valley Air Pollution Control District (air district) and the ARB. The local air district has jurisdiction over stationary area-wide sources of pollution and serves as a coordinating partner in transportation planning for the region. The ARB regulates statewide air pollution sources such as on- and off-road mobile sources and the fuels that power those engines. The proposed plan is required to demonstrate attainment of federal health standards by 2010.
The air district has outlined the following new proposed PM10 controls for the following sources:
The ARB has proposed the following new areas of control in addition to those that have already been previously adopted:
These ARB measures will contribute 10.5 TPD to the plan.
“To be sure we are doing everything possible to address valley pollution I have asked the ARB staff to determine if there is anything more that can be done between now and 2006,” added Lloyd.
In the San Joaquin Valley, PM10 is a complex mixture of particles resulting from primary and secondary sources. Primary sources include dust and soot, while secondary sources include aerosol droplets formed in the atmosphere by precursor chemicals. In winter, nitrogen oxides (NOx) and ammonia react to form particulate ammonium nitrate, which also contributes to ozone formation.
Because these particles are so small, they bypass our body’s defenses, deposit in the respiratory tract and can lodge deep in the lungs. Exposure to airborne particles also aggravates respiratory illnesses like asthma, bronchitis, emphysema and pneumonia.

The Air Resources Board is a department of the California Environmental Protection Agency. ARB’s mission is to promote and protect public health, welfare, and ecological resources through effective reduction of air pollutants while recognizing and considering effects on the economy. The ARB oversees all air pollution control efforts in California to attain and maintain health based air quality standards.
The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. For a list of simple ways you can reduce demand and cut your energy cost, see our website at http://www.arb.ca.gov.
