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.
⚠️ 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.
