Annual Monitoring Network Report

This page last reviewed on January 19, 2017

The draft version of the California Air Resources Board 2016 Annual Network Plan, which covers monitoring operations in 25 Air Districts in California is now available: Annual Network Plan / Appendix A / Appendix B / Appendix C

Any comments or questions regarding the network report should be directed to:
Ms. Gayle Sweigert, Manager, Air Quality Analysis Section at (916) 322-6923.

Federal regulations require that the Annual Network Plan be submitted to the U.S. Environmental Protection Agency (U.S. EPA) after a 30-day public review period.

Note that there are 35 air districts in California. Ten air districts that conduct ambient air quality monitoring are developing separate Annual Network Plans covering the ambient monitoring within their jurisdictions. This Annual Network Plan covers the 25 air districts for which the local air agencies are not drafting a separate report.

Additional information on California's monitoring network can be viewed through ARB's Monitoring Site Information page.
