In many Illinois communities, there are abandoned gas stations or other facilities with no responsible party to pay for cleaning up leaking underground storage tanks. These environmental hazards prevent economic revitalization across the state. The Illinois Environmental Protection Agency (Illinois EPA) intends to close out as many abandoned or orphaned leaking underground storage tank (Leaking UST) sites as possible and issue a No Further Remediation Letter to facilitate the redevelopment of the property for productive re-use as quickly as possible.
