      J.  PROGRAM DESCRIPTION:  Program will compute hazard 
          distances resulting from toxic chemical releases.  It 
          handles instantaneous or continuous, gas or liquid 
          releases from either ground or elevated sources.  
          Program contains additional option for continuous heated
          plumes from stacks.  User enters appropriate 
          meteorological and source characterization data.  
          Program outputs a toxic corridor plotted based
          on specified concentrations, concentration at a 
          specified point, or the location and value of the 
          maximum concentration.
