## Questions

### Who has to register as a UST contractor in Texas?

Any company that installs, repairs or removes underground petroleum storage tank systems in Texas must hold a TCEQ UST contractor registration and employ a TCEQ-licensed on-site supervisor. Every row holds a registration TCEQ shows as current.

### Is there a street address?

No. TCEQ publishes the company's city, ZIP and county for registered contractors, not a street address or phone, so the file carries city, ZIP and county; the map point is the ZIP's centre.

### Are expired registrations included?

No. Only registrations TCEQ shows as CURRENT are in the file; each row carries the registration number, effective date and expiry date.

### Is this list in the Fuel-System Contractor Bundle?

Yes. The bundle puts this list together with the Gilbarco, Veeder-Root and Dover Fueling Solutions networks, the California and Texas tank contractor registers and the independents in one CSV, with a column naming each row's source, for less than buying the lists one by one.

### How current is it?

Snapshot built on October 3, 2026. It is a one-time snapshot and is not rebuilt on a schedule.

### How is this data cleaned?

Every rebuild runs the same steps and counts what each one changed. For the current file, rebuilt October 3, 2026 from www2.tceq.texas.gov: Merged 0 duplicate listings that had the same business name, street address and ZIP code, keeping every filled-in detail from both (October 3, 2026). Unified 1 city names written more than one way within the same ZIP code (for example with and without a space or an abbreviation) to the US Census Bureau spelling (October 3, 2026). Corrected 0 misspelled city names to the US Census Bureau place name for their ZIP code (October 3, 2026). Added map coordinates to 156 listings that had none, from the US Census Bureau address geocoder or, where the street address could not be matched, the centre of the ZIP code (October 3, 2026). Set the county and its federal county code on 50 listings, matched to the US Census Bureau county list from the county the source records, the listing's map point, or its ZIP code area (October 3, 2026). Checked every map point against the state in its address and re-placed 0 points that fell outside that state (October 3, 2026). Flagged 166 addresses that are incomplete, a PO box, or missing a house number, in an address quality column (October 3, 2026). Checked that the row count, state count and field completeness published for this file were measured from the file itself (October 3, 2026).

### Isn't this free on www2.tceq.texas.gov?

The underlying records are public on www2.tceq.texas.gov. What you pay for is the work between that public release and this file: unified 1 city spellings, added coordinates to 156 listings, added the county to 50 listings, flagged 166 incomplete addresses and measured 166 rows. The current file was rebuilt October 3, 2026 from www2.tceq.texas.gov. Doing it yourself means downloading the full release, repeating each of those steps, and repeating them again every time the source updates.

### How complete is each field?

Measured on every row of the current file, the share of rows that carry each key field: city 95%, state 100%, ZIP code 95%, latitude 94%, longitude 94%. 21 of 22 columns are filled on at least half the rows.
