Annual Monitoring Network Report

This page last reviewed on June 24, 2011

The Annual Air Quality Monitoring Network Report for Small Districts in California is now available (PDF) for public inspection until July 24, 2011. Federal regulations require that the air quality monitoring network be reviewed annually to identify any need for additions, relocations, or terminations of monitoring sites or instrumentation. After the 30-day public inspection period, the report will be sent to the U.S. Environmental Protection Agency (U.S. EPA).

Fourteen local air agencies in California that operate monitoring sites are reporting separately on the ambient monitoring within their jurisdictions. This report consists of 25 counties or portions of counties with ambient monitoring sites for which the local air agencies are not drafting a separate report.

The public is invited to review and comment on the draft plan before it is submtited to the U.S. EPA. If you have any questions please contact:

Ms. Gayle Sweigert, Manager, Air Quality Analysis Section at (916) 322-6923.

A separate report is available which includes somewhat different information on the types and time periods of air quality data available from the statewide air monitoring network. This report is called the State and Local Air Monitoring Network Plan, and was last updated in June 2009. The ARB has been compiling and distributing this report for more than two decades.
