# Leaking petroleum storage tank sites in Grayson County, Texas

> 176 LPST cases on the Commission's file in Grayson County, 5 of them still open, with 333 registered storage tanks. Checked against the TCEQ file of 2026-08-21.

## LPST sites in Grayson County

The Commission has recorded **176** leaking petroleum storage tank cases in Grayson County — 0.6% of the Texas total — and **5** of them have no closure date.

### The open cases

**5** of the 176 cases in Grayson County are still
open — 2.8%. The oldest of them was reported in
**1995**, and 4 were reported in 2015
or later.

That spread matters more than the count. An open case from the
1990s usually means a long remediation that was never formally closed; one
from last year means something recent. The file records the two dates and
nothing else — not the substance, not the extent, not what is left to
do. [How to read an open case](/open.md).

### When they were reported

A reporting date is not the date a tank started leaking — it is the date someone found out. In Grayson County the pattern follows the state’s:

| Reported in | LPST cases | Share |
|---|---|---|
| [1980s](/decade/1980.md) | 13 | 7.4% |
| [1990s](/county/grayson/1990.md) | 114 | 64.8% |
| [2000s](/decade/2000.md) | 12 | 6.8% |
| [2010s](/decade/2010.md) | 16 | 9.1% |
| [2020s](/decade/2020.md) | 13 | 7.4% |

### Tanks still in the ground in Grayson County

The Commission’s other file — delivery certificates —
records **333** storage tanks in Grayson County, of which
332 are marked in use. **109** of them sit at a
facility that also has a leak case on record.

That last number appears in neither file: it only exists once
the two are joined on the facility number, which is what this site does.
