Air pollution: covered facilities: community air monitoring systems: fence-line monitoring systems.

Existing law requires a refinery-related community air monitoring system to be installed near each petroleum refinery that meets certain requirements. Existing law requires the owner or operator of a petroleum refinery to develop, install, operate, and maintain a fence-line monitoring system in accordance with guidance developed by the appropriate air quality management district or air pollution control district. Existing law requires the air districts and the owners or operators of refineries to collect real-time data from those monitoring systems, maintain records of that data, and, to the extent feasible, provide to the public the data in a publicly accessible format.
