probability

All > Science > Water
  • The likelihood that the risk (event) will occur. The probability that the event will occur is measured based on the following guidelines:

    High - Greater than or equal to 90 percent. Mitigation efforts must be vigorous and imaginative in order to reduce the probability of occurrence, commensurate with the severity of impact.

    Substantial - Greater than or equal to 75 percent but less than 90 percent. Mitigation efforts must be developed and pursued vigorously commensurate with possible impact.

    Medium - Greater than or equal to 50 percent but less than 75 percent. Mitigation efforts should be developed and pursued commensurate with possible impact.

    Low - Less than 50 percent. Indicates the risk is one that should be monitored, but appears to have been turned around and no action is needed.
