2022 Stationary Source Screening Map Data

The data provides the basis for a screening tool that assess the level of risks and hazards for facilities with permitted stationary sources of air pollution1. The information represents emissions data for the year 2022, submitted to the California Air Resources Board (CARB) as part of the California Emissions Inventory Development and Reporting System (CEIDARS) 2. The CEIDARS data was used to estimate screening level cancer risks (in millions), PM2.5 concentrations (micrograms per cubic meters), and chronic hazard indices at the centroid of each permitted facility. The methodology used to develop the screening tools are presented in Appendix E of the 2022 CEQA Guidelines.

Screening level risks and hazards are intentionally conservative and based on worst-case assumptions. A Stationary Source Data Request can be submitted to obtain the most accurate information permitted source information. Facility level emissions are publicly available on CARB’s CEIDARS report website. A Public Records Request is required to obtain the latest emission inventory for permitted stationary sources to support site-specific Health Risk Assessments.

1 Stationary sources of air pollution—including complex sources such as metal smelting, wastewater treatment plants, and refineries as well as smaller facilities such as diesel generators, gasoline dispensing facilities (GDFs or gas stations), and boilers—are regulated and subject to permit conditions established by the District.

2 The Bay Area Air Quality Management District (BAAQMD) reports emissions from all permitted facilities to the California Air Resources Board (CARB) annually under the California Emissions Inventory Development and Reporting System (CEIDARS).
