Dispersion Models
Incorporated the latest modeling algorithm of continuous buoyant plume/stack release type
in the AFTOX model to align with U.S. EPA AFTOX
Added a feature to allow AFTOX to output maximum concentration at a specified height and
time
Implemented a function to transfer the Source Term Wizard evaporation pool calculation
output to AFTOX model
Fixed the U.S. EPA AFTOX bug regarding maximum concentration at given height and time
Increased the calculation resolution to improve the accuracy of maximum distance
calculation for specific Level of Concern (LOC), which is a bug in the U.S. EPA AFTOX
Disabled incorrect grid and discrete receptor concentration in DEGADIS model
Updated DEGADIS summary results based on the output file to include maximum
concentrations at centerline downwind distance
Enabled the capability for INPUFF model to execute properly on Windows 8 and Windows 8.1
Added maximum concentration contour and steady state concentration contour of SLAB
results in BREEZE 3D Analyst

inconsequential
Source Term Wizard
Updated the dense gas determination method in the Source Term Wizard
Displayed calculated Richardson number in summary results
Added spill rate from vessels for evaporation pool in the results summary file
Removed the stack source type from the Source Term Wizard
Updated compressed gas release (choked flow and unchoked flow) calculation algorithms
Standard Examples
Added examples of finite and instantaneous liquid spill and buoyant plume/stack release for
the AFTOX model
Added examples that export Source Term Wizard output to dispersion models

Bug Fixes:
Fixed map User Interface error caused by map control register problem in the Tatuk control
library
Fixed a bug that prevented AFTOX to run successfully when using observation met data
Fixed a bug that caused incorrect stability parameter calculation in the AFTOX model when
using observation met data
Fixed a bug that displayed a different evaporation rate in the AFTOX summary file as
compared to the User Interface evaporation rate
Fixed a bug that used an incorrect unit for vapor cloud explosion in the TNO Multi-Energy
model
Fixed a bug that caused the loss of the distance message when using the ruler tool in the
Map Tab
Fixed a bug that caused low image resolution when copying and saving an image in the Map
Tab

Known Issues:
Users have to manually input multiple meteorological datasets for the INPUFF model
Users have to currently input maximum surface emissive power for pool fire in the chemical
database
Maximum emission rates calculated in the Source Term Wizard are conservative
The tank source in the Source Term Wizard does not consider leaks through pipes
connected to a tank
