• Abstract:
  This report demonstrates that the probability of violating a "not to be exceeded more than once per year", one-hour air quality standard can be bounded from above. This result represents a significant improvement over previous methods of ascertaining the impacts of pollution sources. Such methods essentially estimated the expected annual maximum concentration and then compared the estimate to that concentration "not to be exceeded more than once per year". The probabilistic method presented in this report is easy to use, inexpensive to implement, and it directly addresses the question of the likelihood of violating an air quality standard. Furthermore, employment of this probabilistic method eliminates the need for the subjective inputs and the subjective analyses of results which characterize the so-called "worst case" methods of determining air quality impact.
