# Underground storage tanks in Greenwich, Connecticut — 151 facilities

> Every facility on Connecticut's underground storage tank register in Greenwich: 151 sites, 559 tanks, 91 still in use. Six DEEP files joined on the facility identifier.

## Storage tanks in Greenwich

The Department has **151** facilities on the tank register at a Greenwich address — 1.2% of the state total — carrying 559 tanks, of which **91** 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 Greenwich the split is:

| Substance recorded | Facilities | Share |
|---|---|---|
| [Gasoline](/town/greenwich/gasoline.md) | 67 | 44.4% |
| [Diesel](/substance/diesel.md) | 38 | 25.2% |
| [Heating Oil(on-site Consumption)](/substance/heating-oil-on-site-consumption.md) | 36 | 23.8% |
| [Not stated](/substance/not-stated.md) | 6 | 4.0% |
| [Used Oil](/substance/used-oil.md) | 4 | 2.6% |

36 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 Greenwich

**86** of the 151 facilities in Greenwich have at
least one tank recorded as bare or asphalt-coated steel —
57.0%. 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 in Greenwich

| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 40 | 26.5% |
| At least one red-tag entry | 15 | 9.9% |
| At least one enforcement action | 40 | 26.5% |
| At least one reported release | 42 | 27.8% |

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.

### A tank on a property in Greenwich?

151 facilities are on the register in Greenwich, 86 with bare-steel tanks recorded. This site tells you a record exists; it is not an assessment. Tell us the address and we pass the request to environmental consultants and tank contractors working in Connecticut.
