The Underground Tank Risk Management (TANKS) Model: User's guide: Final report

This report describes the capabilities and use of EPRI's Underground Tank Risk Management Model (TANKS). TANKS is a sophisticated software system designed to assist in the decisionmaking process regarding tank management strategies. TANKS can address important questions. What should be done with current tanks. What are the best leak detection and other management options for these tanks, and when should they be replaced. What types of tank systems should be installed when a new or replacement tank is needed: What leak detection is best for the selected system. What are the priorities for replacement and leak testing. What are the risks and costs of delaying action. How large are the savings associated with improvements in strategy. How much are risks reduced. Management options that can be assessed include: double-walled tanks and other forms of secondary containment, combinations of leak detection methods, aboveground tanks, tank repair or relining, testing of cathodic protection, and maximum tank age policies. 110 figs., 9 tabs.
