Comparison: State vs. Federal
• Rules. Illinois has regulations that address aboveground flammable and combustible liquid storage tanks. The state has established separate administrative rules for aboveground storage tanks (ASTs) intended to be used for dispensing fuel into motor vehicles, ASTs used for bulk storage purposes, and tanks containing liquid petroleum gas. AST owners and operators should also contact their local fire marshal for any more stringent tank requirements.
For storage tanks that contain hazardous wastes, see the national section HAZWASTE STORAGE AND TREATMENT TANKS for additional information. For underground storage tank regulatory information, see the state section UNDERGROUND STORAGE TANKS.
• Administration and enforcement. The OSFM and local fire departments regulate ASTs that contain flammable or combustible liquids in Illinois.
The installation of regulated tanks (flammable or combustible liquid storage tanks or liquid petroleum gas tanks) requires the filing of a permit application with the OSFM before installation. The following ASTs are subject to the OSFM application and field inspection process:
- All storage tanks intended to be used for dispensing fuels
- All bulk liquid storage tanks for greater than 110-gallon (gal) capacity
