EPA’s Office of Underground Storage Tanks just published this useful bundle of technical support documents:
Natural disasters – such as tornadoes, hurricanes, tsunamis, earthquakes, volcanic eruptions, and fires – are often unpredictable, cause significant damage, and can be costly to mitigate. Underground storage tank (UST) systems can be vulnerable to damage during natural disasters and can even release regulated substances into the environment. Before returning a damaged UST to service, the owner or operator needs to ensure the system has been properly evaluated and restored to safe operating condition.
EPA developed resources to help UST owners and operators prepare for, prevent, or lessen catastrophic effects and environmental harm from natural disasters.
