Indiana has now safely removed or closed more than 500 aging underground storage tanks, marking a significant milestone in its effort to reduce environmental risks and protect nearby communities from future hazardous leaks. This progress is driven by a state law that helps tank owners cover the cost of retiring old or failing systems.
The achievement comes just three years after updates to Indiana Code 13-23, created the nation’s first proactive reimbursement program for underground storage tank (UST) closures. Through the Excess Liability Trust Fund (ELTF), eligible owners can receive 50% of approved decommissioning or replacement costs, making more closures and replacements possible.
“This closure program is a prime example of Indiana leading with practical innovation,” said Gov. Mike Braun. “The state identified a problem and took bold action to prevent potential leaks before they occur, protecting people and communities.”
USTs are found in nearly every community in locations such as convenience stores, fuel stations, airports, police and fire stations, school bus lots and fleet service areas. As USTs reach the end of their lifespan, their potential to leak increases. Leaking USTs can contaminate groundwater, soil and indoor air and may pose a fire hazard. In some cases, contamination can migrate offsite through groundwater, threatening nearby homes and buildings.
The funding has helped remove a practical and ever-present barrier: cost.
"We know that many owners want to address their aging tanks. This program provides the incentive and support they need to move forward, protect communities and prevent future environmental problems,” said IDEM Commissioner Clint Woods.
Since July 1, 2023, IDEM has been allotted $20 million per fiscal year for eligible tank closures. The ELTF program has paid out $20.09 million since the program started.
Owners of aging tanks may be eligible for financial assistance through the ELTF to close, remove, or replace a UST system. More information is available at: on.in.gov/eltf-ust-50
“IDEM’s Office of Land Quality has promoted this program through the inspection process, site cleanups and training opportunities," said Colleen Rennaker, Deputy Assistant Commissioner for the Office of Land Quality. “Our team works diligently to assist owners through the process. Hoosiers are safer and their environment is better protected with every tank removed.”
While each UST is considered by IDEM on a case-by-case basis, certain characteristics may make a UST more likely to qualify for the program:
- USTs over 30 years old.
- USTs which have caused, or are likely to cause, catastrophic release and cannot be repaired or maintained to avoid such release.
