# Underground storage tanks in Willimantic, Connecticut — 79 facilities

> Every facility on Connecticut's underground storage tank register in Willimantic: 79 sites, 364 tanks, 61 still in use. Six DEEP files joined on the facility identifier.

## Storage tanks in Willimantic

The Department has **79** facilities on the tank register at a Willimantic address — 0.6% of the state total — carrying 364 tanks, of which **61** are still in use.

### What is stored, and where it sits

An address on this register is a place with a regulated tank, not
necessarily a filling station. In Willimantic the split is:

| Substance recorded | Facilities | Share |
|---|---|---|
| [Gasoline](/substance/gasoline.md) | 28 | 35.4% |
| [Heating Oil(on-site Consumption)](/substance/heating-oil-on-site-consumption.md) | 25 | 31.6% |
| [Diesel](/substance/diesel.md) | 20 | 25.3% |
| [Not stated](/substance/not-stated.md) | 5 | 6.3% |
| [Used Oil](/substance/used-oil.md) | 1 | 1.3% |

25 of them are
heating-oil tanks kept for the building above — schools, churches,
apartment blocks. They are on the register for the same reason a filling
station is, and they surprise people.

### Bare steel in Willimantic

**60** of the 79 facilities in Willimantic have at
least one tank recorded as bare or asphalt-coated steel —
75.9%. 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 in Willimantic

| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 33 | 41.8% |
| At least one red-tag entry | 14 | 17.7% |
| At least one enforcement action | 32 | 40.5% |
| At least one reported release | 12 | 15.2% |

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.
