A NOTE FROM THE CHAIRMAN . . .

Welcome to the 2006 Edition of the California Air Resources Board’s Almanac of Emissions & Air Quality. This document provides an overview of California’s air quality and the emissions that contribute to our air pollution problem. California’s air quality continues to improve but we face substantial challenges. Attaining air quality standards and addressing air pollution related health risk requires new emission reductions statewide. As the agency responsible for overseeing California’s comprehensive air quality programs we take this public health challenge very seriously.

This document is intended as a reference for the general public as well as those involved in air quality issues on a daily basis. It is part of our commitment to provide broad public access to air quality information. Since air pollution is a complex subject this almanac can only serve as a starting point. However, we hope it provides a common basis for characterizing California’s air quality and emissions. More detailed information on these subjects can be found on our website.

The almanac presents data from both statewide and regional perspectives. Regions are defined as air basins which share a common air mass. In terms of political jurisdictions, we also report data by county within an air basin. To understand trends, we report both current and historical air quality and emissions data.

From statewide summaries to more local county level information, the Almanac is intended to be a “go-to” resource for those interested in California’s air quality. Ensuring easy and straightforward access to information on air quality, our progress, and the remaining challenges should help all Californians to do their part to achieve clean air.

I hope you find this Almanac informative and helpful. The Preface lists e-mail and telephone contacts for your questions or comments. For more information about air pollution, ways to combat it, or the Air Resources Board, please visit our web site at www.arb.ca.gov.

Dr. Robert Sawyer

Chairman, California Air Resources Board

PREFACE


This almanac was prepared and published by the Air Resources Board (ARB) staff to aid air quality professionals and the public in evaluating air quality in California. The ARB, as part of the California Environmental Protection Agency (CalEPA), is the State board responsible for achieving and maintaining healthful air quality in California. This responsibility is shared with local air districts and the United States Environmental Protection Agency (U.S. EPA).

The following staff contributed to the production of this almanac: Andy Alexis, Jeff Austin, Alexa Barron, Vijay Bhargava, Anna Komorniczak, Darryl Look, Chris Nguyen, Marci Nystrom, Ravi Ramalingam, Michael Redgrave, Rajinder Sahota, Webster Tasat, Dr. Patricia Velasco, Robert Weller, and Xijie Zhang. The project was managed by Dr. Linda Murchison, Chief of the Planning and Technical Support Division, Cynthia Marvin, Assistant Division Chief of the Planning and Technical Support Division, Karen Magliano, Chief of the Air Quality Data Branch, Peggy Taricco, Chief of the Emission Inventory Branch, Dr. Michael Benjamin, Chief of the Mobile Source Analysis Branch, Mena Shah, Manager of the Community Assessment & Statistical Analysis Section, and Gayle Sweigert, Manager of the Air Quality Analysis Section.

This is the seventh edition of this almanac which is updated annually as additional air quality and emission inventory data become available. If you find errors or have suggestions for improvements, please let us know. For general issues or issues related to air quality data, contact Paul Cox at (916) 327-7609 or pcox@arb.ca.gov. For issues related to emissions data, contact Martin Johnson at (916) 324-5783 or mjohnson@arb.ca.gov. For issues related to air toxics data, contact Janelle Auyeung at (916) 322-3531 or jauyeung@arb.ca.gov.
