Diesel in Groton
54 of the 127 tank facilities in Groton — 42.5% — hold diesel.
How this group compares
Groton holds 1.5% of Connecticut’s 3,622 diesel facilities, while holding 1.0% of the register overall — so it is over-represented in this one.
Diesel is found at filling stations, but also at depots, garages and any site that fuels its own vehicles.
72 of these tanks are still in use.
Bare steel among these
27 of the 54 facilities among these have at least one tank recorded as bare or asphalt-coated steel — 50.0%. 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.
What the Department’s other files record among these
| Record | Facilities | Share |
|---|---|---|
| At least one recorded violation | 26 | 48.1% |
| At least one red-tag entry | 13 | 24.1% |
| At least one enforcement action | 26 | 48.1% |
| At least one reported release | 24 | 44.4% |
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. What each of these actually is · how a reported release is recorded.
