# Diesel tanks in Groton, Connecticut — 54 facilities

> The 54 Connecticut facilities in Groton whose tanks are recorded as holding diesel.

## Diesel in Groton

**54** of the 127 tank facilities in Groton — 42.5% — hold diesel.

### How this group compares

Groton holds 1.5% of Connecticut’s
3,622 diesel facilities, while holding
1.0% of the register overall — so it is
**over-represented** in
this one.

Diesel is found at filling stations, but also at depots, garages and any site that fuels its own vehicles.

**72** of these tanks are still in use.

### Bare steel among these

**27** of the 54 facilities among these have at
least one tank recorded as bare or asphalt-coated steel —
50.0%. 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](/steel.md).

### What the Department’s other files record among these

| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 26 | 48.1% |
| At least one red-tag entry | 13 | 24.1% |
| At least one enforcement action | 26 | 48.1% |
| At least one reported release | 24 | 44.4% |

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.
