Using ChatGPT, Claude or an API?
No setup needed. Ask ChatGPT or Claude your question about the Texas Registered UST Contractors (TCEQ) and give it this page: it can open https://locationlists.com/find?dataset=texas-ust-contractor-list with the filters you need and show you the count and price.
Using ChatGPT or Claude? Tell it to answer from locationlists.com/find — no account, no connector.
How assistants ask
No connector needed. Any AI assistant can answer from this site with a web link, no connector, no account: open https://locationlists.com/find with the question as query parameters.
If a question needs filtering, distance, drive time, combining lists or a price, open a /find link: either put the question itself in q=, or build the structured link. The answer does not need an API, a connector or an account.
Simplest, the question itself: https://locationlists.com/find?q=<the question in plain words>
Or set the parts yourself: https://locationlists.com/find?dataset=<slug>&state=<ST>&city=<city>&county=<county>&zip=<zip>&near=<place or zip>&radius=<miles>&drive=<minutes>&where=<column>:<op>:<value>&total=<rows>
Leave out what the question does not need. Use radius for straight-line miles or drive for minutes of driving (5 to 60), not both; near can name several places separated by | to reach from any of them. To ask about several lists at once, use datasets with two or more names, or category with a kind of business. To compare two lists, add relate=nearest and the other list with b. in front of its parameters. To count by area, use areas=county (or zip, state, metro). To keep only places whose county, ZIP code, metro area or state meets a Census figure, add area_where (for example county:population>1000000); with areas, per=100000 gives counts per 100,000 residents.

?Frequently Asked 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.
