The short answer
To install underground fuel tanks for a new Texas gas station, the owner must notify TCEQ at least 30 days before construction starts, call the regional office 24 to 72 hours before work begins, and use a TCEQ-licensed installer. The tanks must be registered within 30 days of first storing fuel, and a current delivery certificate is needed before fuel can be delivered.
Which gas station tanks TCEQ regulates
The underground storage tanks, or USTs, that hold gasoline and diesel at a gas station are petroleum storage tanks, and the Texas Commission on Environmental Quality (TCEQ) regulates them under its Petroleum Storage Tank program. TCEQ's Am I Regulated? page walks through which tanks are covered and which are exempt.
For a retail fuel station, the answer is almost always yes. TCEQ's registration and self-certification page says all regulated petroleum storage tanks must be registered unless otherwise exempted or excluded.
The rules for tanks are in the Texas Administrative Code, Title 30, Chapter 334. They cover the whole life of a tank: the notice before it is built, how it is installed, how it is registered, how leaks are detected and how it is eventually taken out of service.
For an owner planning a new station, the tank rules set part of the schedule. The notice period, the installer's licensing and the registration all have to happen in the right order, and the first fuel delivery depends on them. They run alongside the city permits for the store building, the canopy and the site.

The 30-day construction notice to TCEQ
The first step happens a month before anyone digs. TCEQ's page on installing, updating and removing petroleum storage tanks says to submit form TCEQ-0495, the AST and UST Construction Notification, at least 30 days before any construction activity begins, and that construction includes tank and pipe installation.
The registration page adds that the notice can be filed through STEERS, TCEQ's online system, or on form TCEQ-00495. The rule itself is 30 TAC §334.6, Construction Notification for Underground Storage Tanks and UST Systems.
Then there is a second, shorter notice. Between 24 and 72 hours before work begins, the installer or owner calls the TCEQ regional office for the area where the work will happen and reports the time installation will start.
Thirty days sounds simple, but it has to be built into the schedule. If the tank excavation is planned right after site grading, the TCEQ notice needs to be filed while the site work is still being permitted. Missing it does not just add paperwork; it pushes the tank installation, and with it the canopy, the paving and the opening date.

Who is allowed to install the tanks
Not every contractor can put a fuel tank in the ground in Texas. TCEQ's installation page says UST contractors and on-site supervisors with Class A/B combination licenses can install UST systems, and Class A on-site supervisors can install and repair them.
Helpers do not need their own license if they work under the direct, on-site supervision of a licensed on-site supervisor. The licensed supervisor has to be there, not just on the paperwork.
TCEQ points owners to its licensing search to find a licensed contractor, and to its guide RG-475c on how to select one. Ask for the company's registration and the on-site supervisor's license before the tank work is scheduled.
The installer also certifies the work. Under 30 TAC §334.8, an installer hired to install or replace a UST system must certify by signature that the installation methods comply with the state's installation standards, and that certification goes in with the tank registration. On a gas station build, the general contractor coordinates the licensed tank installer with the site work, the canopy and the store so the excavation, the piping and the slab all line up.
Registering the tanks after installation
Once the tanks are in, they have to be registered with TCEQ. The registration page lists form TCEQ-00724 for USTs, and says submitting through STEERS is faster than the paper form.
There is a hard deadline. Under 30 TAC §334.8, the registration and installer certification are due no later than 30 days after the date the tank first stores a regulated substance, which for a gas station means the first fuel in the tank. The form is signed by the tank owner or operator, or their legally authorized representative.
Ownership matters later too. The same rule requires a new certification within 30 days of a change in tank ownership, so anyone buying an existing station has paperwork of their own to file.
TCEQ's guide for owners, RG-475b, Installing a New or Replacement UST, covers the installation and registration steps in more detail and is worth reading before the project starts. Between the construction notice, the regional office call and the registration, the paperwork is spread across the whole build, so one person should own it from start to finish.
The delivery certificate: no certificate, no fuel
A new station cannot just fill its tanks and open. TCEQ says USTs that receive motor fuel deliveries must self-certify at registration or renewal to receive a delivery certificate, and that the certificate authorizes you to receive fuel deliveries and must be renewed every year.
The rule is strict about deliveries. Under 30 TAC §334.8, a delivery of a regulated substance into the tanks cannot be accepted unless the owner or operator has a valid, current delivery certificate available. A temporary delivery authorization can be used instead, but it is valid for no more than 90 days after the first delivery. The certificate has to be posted where it is clearly visible at all times.
The renewal schedule is set by the owner's TCEQ identification number. The rule ties the expiration date to the last digit of the registered owner's number, and the completed renewal form has to reach TCEQ at least 30 days before the certificate expires. Owners also submit proof of current financial assurance each year.
For opening day, this means the registration and self-certification need to be done before the first fuel truck is scheduled, not after. A station with a finished store and canopy but no delivery certificate is a station without fuel to sell.

How the tank work fits into the whole gas station build
The tanks are one part of a project that has a lot of parts: site work and utilities, the tank excavation and piping, the fuel island and canopy, the convenience store building, the coolers and the paving. Most of those depend on the tanks being done first, because the tank pit and the product lines run under the drives and the canopy.
A typical order looks like this:
- Site plan and city permits, with the TCEQ construction notice filed at least 30 days before tank work.
- Site work and underground utilities.
- Regional office call 24 to 72 hours ahead, then tank excavation, tank setting and piping by a licensed installer.
- Canopy foundations and steel, store foundation and building.
- Paving over the tank area and drives, with concrete sized for fuel trucks.
- Registration and self-certification, delivery certificate in hand, then the first fuel delivery.
The store side has its own permits and inspections from the city, including the certificate of occupancy for the convenience store. The tank side runs through TCEQ. Keeping both on one schedule is what gets a station from dirt to open without the two tracks waiting on each other.
Planning a new gas station in Dallas-Fort Worth
A lot of the time on a new station goes into things that happen before construction: the land, the zoning, the site plan and the city's review. The TCEQ steps are not long by comparison, but they are fixed: 30 days of notice, a licensed installer, registration within 30 days of first storing fuel and a delivery certificate before fuel arrives.
That is why it pays to set the order early. File the construction notice as soon as the tank installation date is known, line up the licensed installer before the site is graded, and make one person responsible for the registration and the delivery certificate so the store is not finished and waiting on paperwork.
Remodels of existing stations have their own TCEQ steps when tanks or lines are replaced or removed, and the same installation page covers those. Store remodels without tank work are a city permit matter.
Texas PC Builders builds gas stations and convenience stores across Dallas-Fort Worth, including Fort Worth, alongside restaurants and retail buildings. If you are planning a new station, the best time to talk through the schedule is before the site plan goes to the city.
Questions people ask
How far ahead do I have to tell TCEQ about a new fuel tank?
At least 30 days before construction starts, using form TCEQ-0495 or STEERS. Then a call to the TCEQ regional office 24 to 72 hours before work begins.
Can a new station receive fuel before it gets a delivery certificate?
Not without a valid, current delivery certificate or a temporary delivery authorization, which is good for no more than 90 days after the first delivery.
Do I need TCEQ approval to remodel the store at an existing station?
Work on the store building alone goes through the city's permits. TCEQ's construction notice applies to tank and pipe installation, repair and removal.
