# What Connecticut's tank records actually say

> 28,899 recorded violations, 7,906 red tags, 8,752 enforcement actions, 3,882 reported releases. What each one is, and what none of them measures.

## What each record actually is

Four different things get counted on this site, and they are not interchangeable. Reading them as one another is the commonest way to be wrong about a site.

### A recorded violation

28,899 entries, across 3,479 facilities. Each is *one finding
at one inspection* — a form not filed, a test not run, a record not
kept. Ten entries can be one visit that found ten things, or ten visits. It is
not ten penalties.

The commonest findings in the file:

| Recorded finding | Entries | Share |
|---|---|---|
| Tank Notification Updated | 1,783 | 6.2% |
| Failure to submitt an annual notification and/or annual fee | 1,612 | 5.6% |
| Updated UST notification information required | 1,435 | 5.0% |
| Annual Cathodic Protection Test (Tank) | 1,081 | 3.7% |
| Daily Measurements and Weekly Reconciliation | 1,041 | 3.6% |
| Annual LLD Test Records | 1,001 | 3.5% |
| Annual Cathodic Protection Test | 921 | 3.2% |
| Release Detection Documentation Available | 915 | 3.2% |
| Use Beyond Life Expectancy | 788 | 2.7% |
| Sump Free of Liquid | 766 | 2.7% |

### A red tag

7,906 entries, across 1,593 facilities. A red tag stops fuel
deliveries to a tank until a problem is fixed. It is a real, physical
consequence — and it is temporary by design. A facility tagged in 2011
tells you nothing about that facility today, which is why every count on this
site is shown with dates on the individual record.

### An enforcement action

8,752 on file. These are formal actions the Department opens, and most
carry a status and a resolution. An open action and a resolved one are
different situations under the same word.

### A reported release

3,882 reported, across 2,561 facilities, the most recent on
**2026-08-13**. The file records the substance, the source and the
cause — and nothing about quantity, soil, groundwater or extent.

| Recorded cause | Releases | Share |
|---|---|---|
| Unknown | 2,655 | 68.4% |
| Physical/Mechanical Damage | 581 | 15.0% |
| Corrosion | 289 | 7.4% |
| Overfill | 254 | 6.5% |
| Other; Unknown | 28 | 0.7% |
| Overfill; Physical/Mechanical Damage | 22 | 0.6% |
| Other | 17 | 0.4% |
| Spill | 16 | 0.4% |
| Installation Problems | 7 | 0.2% |
| Corrosion; Overfill | 6 | 0.2% |

The releases file is the one that carries a cause, and the
causes are worth reading on their own. [The reported
releases, by year and by cause](/releases.md).

### ⚠️ What none of them is

None of these four is a measurement. Not one of the six files carries a
concentration, a volume, a depth or a plume boundary. So no page on this site
says a site is polluted, or safe, or clean — those words would be
inventions, and they would be about somebody’s property.

What the files support is narrower and still useful: *a record of this
kind exists at this facility, from this date*. For a records search that is
the job. A phase i environmental site assessment under astm e1527 — the search required by the federal all appropriate inquiries rule (40 cfr part 312) before a buyer can claim the landowner liability protections that cercla offers is the exercise that goes further, and it is
done by a person on the ground.

**Not a consumer reporting agency.** This site
and the datasets sold from it are **not** consumer reports under
the Fair Credit Reporting Act, and must not be used to decide anyone's
eligibility for employment, credit, insurance, housing, or any other purpose
covered by the FCRA. If you need a background check, use a screening company
that operates as a consumer reporting agency.
