An Underground Storage Tank system (UST) is a tank or combination of tanks and connected piping with at least 10% of its combined volume located underground. The tank system includes the tank, underground connected piping, underground ancillary equipment and any containment system.
Over time, USTs may corrode, leak ing their contents into the surrounding soil and eventually our groundwater supply. For this reason, any UST with a capacity for storing petroleum products of 110-gallons or greater is regulated under the Municipal Code of Chicago by the Department of Public Health (CDPH).
Preventing and Reporting Leaks
Owners and operators of USTs are responsible for ensuring that their USTs do not leak. To assist them, DOE has developed the UST Operation and Maintenance Manual for Owners and Operators. See Underground Storage Tank.
Anyone who suspects that a UST is leaking should call the Illinois Emergency Management Agency IEMA at 800.782.7860 within 24 hours of the suspected leak.
To install, upgrade, repair, remove, abandon, install a Stage II vapor recovery system on, or put an interior lining in a UST, you must first obtain a permit from CDPH.
