  1. Texas Air Control Board, Austin, TX (US)
The Texas Air Control Board (TACB) receives numerous reports of process upsets that document releases of pollutants into the atmosphere. These releases represent many different compounds from a variety of release points. In order to help protect the public from adverse effects the TACB has developed a screening technique to identify cases that have the greatest potential for such efforts. This protocol uses an index (Upset Review Index (URI)) which allows upset events to be ranked by their potential adverse health and/or odor effects. The URI is a function of the emission rate and the Threshold Limit Value, odor threshold or other effect guideline. If the URI value is above the screening level, a more thorough review can be conducted which includes dispersion modeling, review of any adverse health effects and maps showing the worst-case air contaminants concentrations. This review is then used to determine if agency action should be taken to minimize the likelihood of future similar process upsets at the plant site.
