Index method for cost-effective assessment of risk to the environment from accidental releases

摘要

The objective of this study was to develop a methodology by which the risk from major accident hazards to the environment can be assessed or quantified. An index method, the Environmental Risk Index (ERI), has been developed based on an existing method, the Environmental hazard Index (EHI), and the Department of the Environment (DoE) definitions of events that would constitute a major accident to the environment. The method includes proposed criteria for risk tolerability. The method requires more extensive testing and revision to accommodate forthcoming revisions to the DoE criteria for major accidents to the environment.
