Monitoring Stations

The California Air Resources Board (ARB) maintains a website with technical information on all of the monitoring stations operated throughout the state, including our county.

2019 Ambient Air Monitoring Network Plan

The 2019 Ambient Air Monitoring Network Plan is an annual examination and evaluation of the APCD's network of air pollution monitoring stations. The annual review of the state and local air monitoring stations network is required by Title 40, Code of Federal Regulation, Part 58.10. Public comment on the plan was accepted until midnight, June 24, 2019. This plan, along with any public comments received was submitted to the EPA on July 1, 2019. 

Network Assessment

The network assessment is a more detailed examination and assessment of the more technical aspects of the monitoring program performed every five years. The last network assessment was completed in 2015.
