Worst Case Scenario

USEPA requires that facilities with Program 2 or 3 processes conduct an Offsite Consequence Analysis that consists of identifying a Worst Case Scenario and an Alternative Release Scenario to identify the potential reach and consequences to both public and environmental receptors.   

Identifying the Worst Case Scenario consists of identifying and analyzing a worst case release which has the greatest potential of reaching an endpoint distance.  Identifying the Alternative Release Scenario involves identifying more realistic release scenarios which still have the potential to impact off-site public and environmental sources. 

If your process is new, has changed significantly, or needs to be updated based on the 5 year period, HEI can assist in documenting and submitting the process while using the most current available data.
