This session addresses the massive challenge to Underground Storage Tank (UST) and Leaking Underground Storage Tank (LUST) programs of a wave of aging UST systems nationally. How big of an issue is it, really? What does it look like in terms of national data, and from the inside of a 30 year old system? Most states don't yet require older UST systems be removed, so this session will communicate how some states have attempted to limit their downsides and require or encourage the removal of older UST systems through various regulatory, compliance assistance, or funding approaches. What did they do, and what did they learn? What lessons might be helpful for your own state?
