Petroleum & Chemical Safety

Underground Storage Tanks (UST)

The Division of Petroleum & Chemical Safety was created to manage the problems caused by the thousands of underground storage tank systems containing petroleum or hazardous chemicals. The division regulates petroleum and chemical storage tanks through registration to ensure the protection of public health and safety. The division has registered more than 73,000 tanks in Illinois. Other duties include issuing permits for all tank installations, removals, repairs, upgrades, relining and abandonment-in-place. Eligibility and deductibility determinations are also made to determine if a tank owner can access the leaking underground storage tank fund. Inspectors in this division respond to petroleum and chemical leaks and spills.
