The University of Texas at Dallas (UT Dallas) developed the E-Plan real-time chemical plume modeling for first responders use only. This tool is used primarily for planning situations, where the goal is to assess the threat posed to the general public by a chemical release.


Authorized E-Plan users can use this mapping tool to plot a chemical plume and view census information on a Google map. Public facilities such as schools and hospitals are provided within the potential impacted circle. This plume model has been extensively tested with selected first responders.
