Diesel
3,622 of Connecticut’s 12,749 registered tank facilities hold this — 28.4%, with 4,233 tanks still in use.
What it is here
Diesel is found at filling stations, but also at depots, garages and any site that fuels its own vehicles.
Bare steel among these
1,821 of the 3,622 facilities among these have at least one tank recorded as bare or asphalt-coated steel — 50.3%. That is the construction the federal upgrade rules were written to replace: unprotected steel in wet ground corrodes, and corrosion is how a tank starts leaking.
A bare-steel tank on the record is not a leak and not a breach — many are long closed, and the file records the construction, not the condition. It is simply the one physical fact in these files that bears on risk. Why this is the number worth knowing.

What the Department’s other files record among these
| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 1,683 | 46.5% |
| At least one red-tag entry | 1,047 | 28.9% |
| At least one enforcement action | 1,617 | 44.6% |
| At least one reported release | 1,462 | 40.4% |
These are counts of records, not judgements. A violation entry is one finding at one inspection; a red tag stops deliveries until a problem is fixed and says nothing about today; a release is a report, with no measurement of what was spilled or how far it went. Which facility carries which is on its own record, one search away. What each of these actually is · how a reported release is recorded.
