Additional RCRA Information:
Risk Management is a distinctly different process from risk assessment. Risk assessment establishes whether a risk is present and, if so, the range or magnitude of that risk. In the risk management process, the results of the risk assessment are integrated with other considerations, such as economic or legal concerns, to reach decisions regarding the need for and practicability of implementing various risk reduction activities. Risk managers also use risk assessment results as a basis for communicating risks to interested parties and the general public.
Risk managers may also employ consensus based approaches, such as the Risk-Based Decision-Making (RBDM) process, in which decisions are made about contaminated sites according to the risk each site poses to human health and the environment using general protocols. Underground storage tank (UST) implementing agencies often use RBDM to make determinations about the extent and urgency of corrective action needed and about the scope and intensity of their oversight of corrective action activities by UST owners and operators.
