The presence of an underground storage tank (UST), whether in use or out of service, could mean that your facility is subject to additional regulations. It’s possible that you have an underground storage tank, but are not aware of it. If you have items resembling those depicted to the left, you will need to examine them further to determine if you do have a UST.

(1) Does your facility have any underground storage tanks (USTs)?

If “NO”, skip question 1a.

(2) Do you have petroleum or hazardous substance containing UST(s) (one hundred ten (110) gallons or more) that have not been registered with IDEM?

Note: Underground storage tanks storing fuel for heating are exempt.

If you have a UST(s) that has not been registered with IDEM, you will need to submit an RTC plan form. To be in compliance, you will need to contact IDEM’s Office of Land Quality - Underground Storage Tank Section at (317) 308-3024 to register or close your tank.
