The largest USTs in the US and perhaps the world are being evaluated for upgrade alternatives. Ben Thomas of UST Training had the good fortune of visiting this one-of-a-kind UST system in Honolulu, Hawaii 2015 and got to see firsthand this engineering marvel. Since then Ben has been leading the nation in operator training for previously deferred tanks such as those at Red Hill and other field constructed tanks and airport hydrant systems that will be subject to UST regulations in the next few years. Stay tuned for more information on the wedding of previously deferred USTs and operator training.
