## Storage tanks in Douglas County

The Division has **495** facilities on the register in Douglas County — 2.5% of the state total — carrying 1,074 tanks, of which **516** are still in use.

### What kind of sites these are

A tank on this register is not necessarily a filling station. In
Douglas County the register breaks down as:

| Facility category | Facilities | Share |
|---|---|---|
| [Retail Gas Station](/county/douglas/retail-gas-station.md) | 120 | 24.2% |
| [Other](/county/douglas/other.md) | 96 | 19.4% |
| [Commercial/industrial](/county/douglas/commercial-industrial.md) | 95 | 19.2% |
| [Emergency Generator Only](/category/emergency-generator-only.md) | 63 | 12.7% |
| [State/local Government](/category/state-local-government.md) | 61 | 12.3% |
| [Lpg Only](/category/lpg-only.md) | 31 | 6.3% |
| [Auto Maintenance Facility](/category/auto-maintenance-facility.md) | 13 | 2.6% |
| [Farm/residential](/category/farm-residential.md) | 10 | 2.0% |
| [Federal Government](/category/federal-government.md) | 2 | 0.4% |
| [Petroleum Distributor](/category/petroleum-distributor.md) | 2 | 0.4% |
| [Railroad](/category/railroad.md) | 1 | 0.2% |
| [Airport](/category/airport.md) | 1 | 0.2% |

63 of them exist only
to run a standby generator, and 31 hold propane rather
than petroleum. Neither behaves like a petrol station, and neither is what
people picture.

### Bare steel in Douglas County

**64** of the 495 facilities in Douglas County have at
least one tank recorded as asphalt-coated or bare steel —
12.9%. That is the material the federal upgrade rules were
written to replace: unprotected steel corrodes, and corrosion is how a tank
fails.

It describes what a tank is *made of*, not what
condition it is in, and many such tanks are long closed.
[Why it is still the number to know](/steel.md).

### Petroleum releases in Douglas County

**209** of the 495 facilities in Douglas County have a
release on record — 42.2%. Of those,
**13** have one that is *not yet closed*
, and **1** have one the State is running itself.

**7** of them still have tanks in use.

Colorado records the *stage* a cleanup has reached, not
merely open or closed — characterisation requested, plan being
implemented, state lead. That distinction is the useful part, and it is on
each facility’s own record. [What each stage
means](/stage.md).

### Cities and towns in Douglas County

| City | Facilities | Share |
|---|---|---|
| Castle Rock | 120 | 24.2% |
| Parker | 112 | 22.6% |
| Littleton | 80 | 16.2% |
| Highlands Ranch | 63 | 12.7% |
| Sedalia | 37 | 7.5% |
| Englewood | 32 | 6.5% |
| Lone Tree | 16 | 3.2% |
| Franktown | 13 | 2.6% |
| Larkspur | 12 | 2.4% |
| Castle Pines | 6 | 1.2% |
| Louviers | 4 | 0.8% |

Cities do not get pages of their own: a city page would be a subset of this one, and two pages describing the same facilities is how a site starts repeating itself.
