Top Five Common Violations for Underground Storage Tank (UST) Facilities:

The top five common violations for petroleum Underground Storage Tank (UST) facilities in 2016 involved failure to provide leak detection for USTs, failure to have Financial Responsibility, failure to submit notification for USTs to IDEM, failure to maintain proper release detection methods for piping and failure to provide proof of Financial Responsibility. In addition, an UST owner or operator needs to maintain accurate and current records and be able to produce these records upon IDEM request. Following are Indiana Administrative Code (IAC) citations for each requirement and the Indiana Department of Environmental Management’s (IDEM’s) recommendations for avoiding these common environmental violations [PDF].
