Monthly Air Monitoring Report 

The monthly air monitoring report is prepared by the APCD for the Air Pollution Control Board monthly meeting. The reports are a basic air-monitoring summary that include monitoring data for "criteria" pollutants like ground-level zone (O3), fine particle pollution (PM2.5), and sulfur dioxide (SO2). The monitored levels of these pollutants are used to determine the Air Quality Index (AQI) as well as our area’s attainment with National Ambient Air Quality Standards

The air monitoring report for each month is made available prior to the Air Pollution Control Board meeting the following month. Reports below are sorted by the month the data was collected.

Monthly Air Toxics Report 

The monthly air toxics report is prepared by the APCD for the Air Pollution Control Board monthly meeting. An air toxic is any air pollutant that is not a “criteria pollutant” (see question above), but may reasonably be anticipated to cause serious chronic or acute health effects in humans at certain levels. The APCD has now added equipment capable of monitoring for air toxics at two of its air monitoring sites, 2730 Cannons Lane and 4201 Algonquin Parkway. This new technology allows the District to collect data in near real time on concentrations of a variety of air toxics, which have traditionally been much more difficult and expensive to monitor for. 

Due to quality assurance procedures, Monthly Air Toxics Reports are issued on a delayed schedule. Reports below are sorted by the month the data was collected.

Emissions Dashboards and Data 

The National Emissions Inventory, released every three years, is based primarily upon emissions data provided by State, Local, and Tribal air agencies for sources in their jurisdictions and supplemented by data developed by the US EPA. The result is a comprehensive and detailed estimate of air emissions of criteria pollutants, criteria precursors, and hazardous air pollutants from air emissions sources. You can learn more about local sources of air pollution in the Emissions Inventory Dashboard below.
