Storage tanks in Darien

The Department has 63 facilities on the tank register at a Darien address — 0.5% of the state total — carrying 333 tanks, of which 50 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 Darien the split is:

19 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 Darien

31 of the 63 facilities in Darien have at least one tank recorded as bare or asphalt-coated steel — 49.2%. 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 in Darien

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.
