Sacramento Metropolitan Air Quality Management District
Mobile Sources Air Toxics Protocol Tool

Welcome to the online tool for the Sacramento Metro Air District Mobile Sources Air Toxics Protocol. The tool is designed to be used in conjunction with the Guidance and Methodology documents.

This tool provides a conservative analysis of cancer risk and PM2.5 concentrations for receptor points extending two kilometers out from roadways where at least 100,000 vehicles travel daily on average, and rail lines, within Sacramento County.

This tool does not reflect existing features on or adjacent to the location of interest that may reduce risk such as barriers, tree plantings, or enhanced indoor filtration.

Basic Tool Instructions:

  • Zoom in to show the receptor grid and highway and rail road link names. Click on a blue dot at your location of interest to see the cancer risk and PM2.5 concentrations.
