# Underground storage tanks in Colchester, Connecticut — 51 facilities > Every facility on Connecticut's underground storage tank register in Colchester: 51 sites, 193 tanks, 36 still in use. Six DEEP files joined on the facility identifier. ## Storage tanks in Colchester The Department has **51** facilities on the tank register at a Colchester address — 0.4% of the state total — carrying 193 tanks, of which **36** 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 Colchester the split is: | Substance recorded | Facilities | Share | |---|---|---| | [Gasoline](/substance/gasoline.md) | 18 | 35.3% | | [Diesel](/substance/diesel.md) | 16 | 31.4% | | [Heating Oil(on-site Consumption)](/substance/heating-oil-on-site-consumption.md) | 13 | 25.5% | | [Not stated](/substance/not-stated.md) | 3 | 5.9% | | [Used Oil](/substance/used-oil.md) | 1 | 2.0% | 13 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 Colchester **34** of the 51 facilities in Colchester have at least one tank recorded as bare or asphalt-coated steel — 66.7%. 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 Colchester | Record | Facilities | Share | |---|---|---| | At least one recorded violation | 20 | 39.2% | | At least one red-tag entry | 7 | 13.7% | | At least one enforcement action | 17 | 33.3% | | At least one reported release | 10 | 19.6% | 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.
