Air District Fact

The BAAQMD's Carl Moyer Program provides grants primarily for installing new, cleaner engines or emission-control devices in heavy-duty equipment, such as trucks and buses, marine vessels, construction equipment, locomotives, and agricultural irrigation pumps.

Tools & Methodology

The air quality analysis tools below are intended to assist lead agencies in analyzing air quality impacts from proposed land use projects and plans. Refer to the District's CEQA Guidelines for additional guidance on how to analyze and mitigate specific air quality impacts.

The District's CEQA community risk and hazards screening tools and tables are provided for lead agencies to consider in deciding whether there should be further environmental review of a project. The screening tables are intentionally conservative, such that if a project passes the initial screen, no additional review related to the impact is necessary. The screening tables are not intended to be used to assess actual risk for all projects. The screening tables are not intended to discourage infill development or affordable housing. If a project does not pass the initial screen, a more advanced screening analysis should be conducted. It is anticipated that most projects that do not pass the initial screen will pass the screen with more refined analysis. The screening tables will continue to be updated to reflect the best available data. To contact the District for additional guidance on the screening tables and to conduct a more advanced screening analysis, please use the Stationary Source Inquiry Form in the table below the flow chart.

The flowchart below (see the full size version) provides detailed steps on how to use the District's screening tables for estimating potential risk and hazard impacts:

Recommended Methods for Screening and Modeling Local Risks and Hazards - describes in detail  how to screen and model risk and hazards from stationary, highway, and roadway sources. Also discusses the assumptions and methodologies used in developing the stationary source, highway, and roadway screening tools.

Highway Screening Analysis Tool- Google Earth map tool to identify estimated risk and hazard impacts from highways throughout the Bay Area.  Google Earth must be installed to run files. Click on different segments of the highways to view estimated risk and hazard impacts that represent the average annual daily traffic (AADT) count, fleet mix and other modeling parameters specific to that segment of the highway.  The estimated risk and hazard impacts were modeled at two different heights, 6ft. and 20 ft.  The 6 ft. height estimates should be used when receptors are located on the ground floor of a building; and the 20 ft. height estimates should be used when receptors are located on the second floor of a building.
