Risk Based Decision Making and Underground Storage Tanks (USTs)
Risk-based decision-making (RBDM) is a process to make decisions about underground storage tank (UST) release sites based on the risk each poses to human health and the environment. EPA developed a comprehensive policy that explains the use of risk-based approaches at UST sites.
States are the primary implementers of the UST program. Check with your state agency to see if they use RBDM and to find out the specifics of their program.
