Tank Status Breakdown
All 31,900 records by current regulatory status.
Top Products Stored
Active tanks only. Renewables are a small but growing share.
Facility Types
Gas stations dominate, but USTs span a wide range of facility categories statewide.

Cleaner Fuels Need Better Infrastructure
Only 5.9% of active tanks statewide store renewable fuels like E85 or ethanol. Upgrading storage and dispensing equipment costs roughly $320,000 per facility — out of reach for most independent operators. A $12M grant program funded entirely from the existing UST Fund (currently $82M and growing) would directly close this gap at zero cost to general revenue.

Renewable vs. Conventional
The vast majority of active tanks still store conventional fuel only.
Renewable: 1,037 tanks
Conventional: 16,600 tanks
Only 597 active E85 tanks serve Illinois drivers statewide.
E85 Tanks by County
Concentrated in northeastern Illinois. Large downstate areas have little to no E85 infrastructure.
The Fund Math
HB4838 / SB2965 transfers $3M per quarter for four quarters — only while the UST Fund maintains a $50M minimum balance.

Context: IEPA's own bill (HB4960 / SB3667) proposes moving $5M out of the fund annually in perpetuity into the Brownfields Redevelopment Fund. If the fund can sustain an ongoing $5M annual draw, a one-time $12M finite transfer is well within bounds.
⏳
The Clock Is Ticking Underground
Typical UST warranties last 30 years. Tanks installed before January 1, 1976 — now at least 50 years old — are at the highest risk of corrosion and leaks. IEPA and OSFM data estimates roughly 650 such tanks exist statewide. Registry data confirms 563 are still actively in use today. Every day without action is a day closer to soil and groundwater contamination.

Age Profile of Active Tanks
Installation decade of all tanks currently in service. Red bars pre-date 1976.
Pre-1976 Tanks by Facility Type
Most aged tanks are at retail gas stations — but hospitals, utilities, and schools are also affected.
