The development of alternative case scenarios for hazard analyses under {section}112(r)(7)
- Woodward-Clyde Consultants, Lexington, MA (United States)
EPA`s 112(r)(7) rule, which requires the preparation of Risk Management Plans, requires sources to perform offsite consequence analyses for a worst case release scenario and also for alternative (more likely to occur) scenarios. The worst case scenarios are well defined by the regulation and will be recognized for most situations as over predicting the potential impact of a release major factors. Model selection does have an effect on calculated distances to toxic endpoints. However, as is shown, the magnitude of these results does not vary greatly. The need to define alternative scenarios presents an opportunity for sources to consider much more carefully what a more likely to occur (although, hopefully also improbable) accident might pose as a threat to the public. Precautionary and preventative as well as mitigative measures become more important to the actual safety of the public.
