Risk Characterization
Workgroup Summary
The Risk Characterization Workgroup discussed how risk assessment could be
used to improve dredged material management decisions. The group considered
when and how risk-based thinking and uncertainty analysis tools could be
incorporated into permit decisions. These discussions resulted in a recommended
risk-based decision framework. The framework calls for a level of analytic effort
commensurate with the complexity of the decision to be made. The group also
identified research priorities for improving the characterization of risk associated
with dredged material operations and disposal.
Risk Assessment and Uncertainty Analysis
in Dredged Material Management Decisions
The group reached a general consensus that risk assessment and uncertainty
analysis should be an integral part of the dredged material management process.
However, the group voiced many concerns regarding how this goal can be
accomplished. These concerns may be summarized as follows:
a. Risk assessment may facilitate approval of a project that should not be
approved.
b. Risk assessment may possibly delay decisions and add to project costs
presumably due to additional time needed for analysis.
c. Acceptable levels of risk are difficult to define.
d. Risk assessment is undemocratic, because only experts understand it well.
e. The dredged material management decision process is adequate; therefore,
there is no need to modify it.
f.
Data requirements could be substantial.
