An inside look at aging underground storage tanks
Underground storage tanks are aging, and becoming an increasingly frequent topic of discussion, research, and concern. As single-walled tanks, both fiberglass and steel, approach the end of their useful life they need to be removed from service, relined, or tested more frequently. In order to accomplish this, large operators may be looking at a significant capital expenditure and sometimes, strict deadlines. Some tanks may have deteriorated, while some may be in good working condition and pose less of an environmental risk. From the forecourt, operators might not know which category their tanks fall into.
