AirToxScreen Mapping Tool from the EPA Air Toxics Screening Assessment

Please answer questions carefully, according to guidelines.

Visit the AirToxScreen Mapping Tool from the EPA Air Toxics Screening Assessment.
• Click “Zoom to State(s)” and type in your state. Then click “Zoom to County(s)” and type in your county to navigate to your area on the interactive web map tool.
• Find the “selector tool” in the upper left corner of map (drop down menu).
• Use the selector tool to outline an area around your community (rectangle or circle are the easiest selectors to capture the tract area).
• Once the area is selected, the charts and lists under the map window populate with content about air quality risk level in the selected tract.
• If you need to redo the selection, then click the ‘x’ in the upper left of the map window by the number of tracts selected (will only appear after tract(s) are selected). The “x” clears the data so that you can reselect another tract.
• Observe the Tract Location Data, Risk by Air Toxic, Risk by Source Type, and Facility Emissions for the location you selected. You may want to use this information as you create your video.
