Richmond-San Pablo Stationary Source Emissions Inventory


This mapping tool visualizes emissions data (criteria air pollutants and air toxics) from permitted facilities in Richmond-San Pablo, California. Users can select individual facilities, view their reported emissions, and filter and compare the results by pollutant, facility, and sector type.

Richmond-San Pablo Stationary Source Emissions Inventory


The database of permitted facilities and reported emissions used in this visualization was compiled using the California Air Resources Board’s (CARB) Facility Search Engine. The data shown is for 2019. Annual emissions are reported to the California Air Resources Board through the Criteria Pollutant and Toxics Emissions Reporting (CTR) Program.

2 NOX = nitrogen oxides (reported as equivalent amounts of NO2); SOX = sulfur oxides (reported as equivalent amounts of SO2); CO = carbon monoxide; PM2.5 = particulate matter less than or equal to 2.5 microns in diameter.

Criteria air pollutants are six common air pollutants regulated by the US Environmental Protection Agency (EPA). They are the only air pollutants with National Ambient Air Quality Standards (NAAQS) that define allowable concentrations in ambient air. The six criteria pollutants are CO, SO2, NO2, PM, ozone (O3) and lead (Pb). Lead is shown here in the Air Toxics tab, as reported in CARB’s facility emissions inventory.

Air toxics, or toxic air pollutants, are air pollutants for which exposure may be associated with adverse health effects.

5 This inventory only covers emissions from permitted facilities and does not include other key area-wide sources of PM, like fugitive dust and residential wood combustion.
