Underground Storage Tanks

The Underground Storage Tanks program is responsible for assuring that all regulated underground storage tanks meet the U.S. EPA's and Indiana's requirements for release detection, spill and overflow prevention and corrosion protection, and to insure that tanks not meeting those requirements are properly closed or upgraded. The section educates and assists underground storage tank owners and operators in order to encourage and promote voluntary compliance.

Featured Topic: Underground Storage Tank Fee Billing

House Bill 1342 has shifted collecting taxes to IDEM. IDEM will collect UST fees on a calendar year of January 1 to December 31. You will receive an invoice around March of 2015 which will be for the last 6 months of 2014 and the calendar year of 2015, for an 18 month billing period.

Featured Topic: UST Operator Training

IDEM Offers Free Online Training to Underground Storage Tank (UST) Owners and Operators

As of August 8, 2012, all of Indiana’s approximately 4,000 UST facilities, most of which are gas stations, must designate individuals as Class A, Class B, and Class C operators for various responsibilities of system operations. Class A, Class B, and Class C operators must be certified in various aspects of system maintenance and operations. IDEM is providing the required training and certification program for free.

  • Class A status is for individuals, such as owners, who hire or contract the personnel who are responsible for day to day maintenance and record keeping.
  • Class B status is for individuals, such as consultants or full-time employees, who the facility owner has designated for the operation of all aspects of the system’s operation and maintenance.
  • Class C status is for facility employees, like cashiers, who assist Class A and Class B operators in monitoring for problems and responding to emergencies. Class C operators may be trained by the Class A or B for the facility or their designee.
The UST Operator Training system can experience extremely high submission volume at this time. Some users may experience the system timing out and returning you to the login screen while attempting to click through the screens, or while submitting your test. If this happens to you, please log back in and retake the test. Once you have received your certification in your email, you do not need to take the test for that certification again.
