# Underground storage tanks in Stonington, Connecticut — 43 facilities

> Every facility on Connecticut's underground storage tank register in Stonington: 43 sites, 113 tanks, 12 still in use. Six DEEP files joined on the facility identifier.

## Storage tanks in Stonington

The Department has **43** facilities on the tank register at a Stonington address — 0.3% of the state total — carrying 113 tanks, of which **12** 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 Stonington the split is:

| Substance recorded | Facilities | Share |
|---|---|---|
| [Gasoline](/substance/gasoline.md) | 18 | 41.9% |
| [Diesel](/substance/diesel.md) | 13 | 30.2% |
| [Heating Oil(on-site Consumption)](/substance/heating-oil-on-site-consumption.md) | 11 | 25.6% |
| [Not stated](/substance/not-stated.md) | 1 | 2.3% |

11 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 Stonington

**31** of the 43 facilities in Stonington have at
least one tank recorded as bare or asphalt-coated steel —
72.1%. 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 Stonington

| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 14 | 32.6% |
| At least one red-tag entry | 6 | 14.0% |
| At least one enforcement action | 12 | 27.9% |
| At least one reported release | 8 | 18.6% |

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.
