Final answer:
The program in Illinois that governs underground storage tanks is called the Underground Storage Tank Program.
Step-by-step explanation:
The program in Illinois that governs the detection, identification, monitoring, mitigation, and removal of buried underground storage tanks is called the Underground Storage Tank (UST) Program.
The UST Program is administered by the Illinois Environmental Protection Agency (IEPA). Its purpose is to protect human health and the environment by preventing leaks and spills from underground storage tanks.
Under this program, owners and operators of USTs are required to comply with regulations for installation, operation, maintenance, closure, and corrective action. The IEPA conducts regular inspections and ensures proper monitoring to identify and address any potential risks or issues.
