Guidelines for selecting scenarios for risk management plan hazard assessments
Planned Environmental Protection Agency (EPA) regulations required by the 1990 Clean Air Act Amendments (CAAA) necessitate the development of Risk Management Programs (RMP) by facilities that handle hazardous materials in excess of identified threshold levels. These RMP`s must include hazard assessments of the potential offsite consequences resulting from the accidental release of these regulated substances. This paper discusses methodologies that are available to screen these scenarios and eliminate those that are not likely to occur or even if they were to occur, would not affect people or the environment beyond the facility boundary. These methods include: the estimation of accidental release probabilities and the application of parametric dispersion analyses. These methodologies can be combined to quickly identify those accident release scenarios that would have no offsite impact and to develop a simplified risk ranking that would prioritize the remaining scenarios. This procedure will provide the selection justification required by the RMP regulation. The analyst can select the appropriate number for evaluation from the highest risk scenarios.
