2007 Southern California Wildfires and High Winds
This widely documented event began with high winds from a surface cold front and the ignition of the Ranch Fire in Los Angeles County on Saturday, October 20, 2007. Numerous additional fires were fueled by strong Santa Ana winds, which helped spread smoke, dust, and ash throughout Southern California. On October 21, the Governor of California declared a State of Emergency for Los Angeles, Orange, Santa Barbara, Ventura, Riverside, San Bernardino, and San Diego Counties. The Federal Emergency Management Agency (FEMA) followed suit on October 24, declaring all seven counties disaster areas. At its peak, the deadly Southern California Fire Siege comprised almost 20 major wildfires, with several smaller fires contributing to the pall of smoke over the region. By the time the last fire had been declared contained on November 13, over a half-million acres had burned, thousands of buildings had been destroyed, and almost a million residents had been displaced.
Although most monitoring sites in the region were affected, ARB is requesting exclusion of data from 14 sites in five Air Districts where smoke, dust and ash caused levels to exceed those historically seen the fall season.
1. The event meets the definition of an exceptional event;
2. There is a clear causal relationship between the measurement under consideration and the event that is claimed to have affected air quality in the area;
3. The event is associated with a measured concentration in excess of normal historical fluctuations, including background; and,
4. There would have been no exceedance or violation but for the event.
