Proposed EPA regulations require that metallic underground storage tank (UST) systems be upgraded to new tank standards within a ten year compliance period. Retrofitting existing metallic UST systems with impressed current cathodic protection systems is one upgrade option available to tank owners. The proper selection of the tank systems to be retrofitted with cathodic protection and the order that they are to be retrofitted in the ten year compliance period are an important factor in minimizing environmental risks. Once the tank systems have been selected and prioritized, a cathodic protection system must be properly designed and installed to be effective. Many types of cathodic protection system programs have been utilized on underground tanks in the past but they have not always been successful. Proper design and selection of cathodic protection components results in the most practical and economic approach not only to meet the proposed Federal UST regulations but also to minimize environmental risks. Establishment of a monitoring and maintenance program ensures that the cathodic protection retrofit program remains functional and effective for many years into the future.
