# Underground storage tanks in Niantic, Connecticut — 38 facilities > Every facility on Connecticut's underground storage tank register in Niantic: 38 sites, 246 tanks, 31 still in use. Six DEEP files joined on the facility identifier. ## Storage tanks in Niantic The Department has **38** facilities on the tank register at a Niantic address — 0.3% of the state total — carrying 246 tanks, of which **31** 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 Niantic the split is: | Substance recorded | Facilities | Share | |---|---|---| | [Diesel](/substance/diesel.md) | 20 | 52.6% | | [Gasoline](/substance/gasoline.md) | 16 | 42.1% | | [Used Oil](/substance/used-oil.md) | 1 | 2.6% | | [Heating Oil(on-site Consumption)](/substance/heating-oil-on-site-consumption.md) | 1 | 2.6% | 1 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 Niantic **20** of the 38 facilities in Niantic have at least one tank recorded as bare or asphalt-coated steel — 52.6%. 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 Niantic | Record | Facilities | Share | |---|---|---| | At least one recorded violation | 18 | 47.4% | | At least one red-tag entry | 13 | 34.2% | | At least one enforcement action | 17 | 44.7% | | At least one reported release | 14 | 36.8% | 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.
