ABSTRACT
During the 1960s and 1970s it became clear that the era of dominance for unprotected steel underground storage tanks was near an end, which led steel tank manufacturers to develop several technologies that would better serve UST customers. The tank technologies during the past three decades have reflected distinctions between unique approaches to providing corrosion protection and enhancing the long-term reliability of steel USTs. The technological approaches can be divided into several categories:
Cathodic protection Composite Jacketed Thick urethane coated
The technologies, covering tanks fabricated by dozens of different manufacturers, have in many cases built national identities because they were backed by technical standards cited in federal and state regulations for USTs.
