How to Fill Out Texas TCEQ Petroleum Storage Tank Registration + FAQs

The Texas TCEQ Petroleum Storage Tank Registration (Form TCEQ-0724, Revised 03/2023) is the official document that every owner of a regulated underground or aboveground petroleum storage tank in Texas must file with the Texas Commission on Environmental Quality to legally place a tank into service, transfer ownership, or self-certify ongoing compliance. The form ties each tank to a Regulated Entity Number (RN), a Customer Number (CN), and an annual fee that funds the state’s groundwater protection program under 30 TAC Chapter 334.

According to TCEQ’s most recent Petroleum Storage Tank Program annual report, Texas regulates more than 170,000 active and temporarily out-of-service tanks at roughly 38,000 facilities, and the agency rejects or returns nearly 1 in 5 registration submittals for missing fields, wrong RN numbers, or unsigned certifications. Filing this form correctly the first time avoids a 30-day deficiency letter and the risk of operating an unregistered tank, which carries penalties of up to $10,000 per tank per day under Texas Water Code §26.3475.

Here is what this guide covers:

• 🛢️ What Form TCEQ-0724 is, who must file it, and which tanks fall under TCEQ jurisdiction
• 📋 Every document, ID number, and operator certification you must gather before you start
• ✍️ A line-by-line walkthrough of every box on the registration and self-certification form
• 🏪 Three full filled-out scenarios for a new station owner, a municipal fleet, and an annual self-certifier
• ⚖️ The deadlines, fees, penalties, and post-filing steps that keep your facility in good standing

What the Form Is and Who Must File It

Form TCEQ-0724 is the Petroleum Storage Tank Registration and Self-Certification form used by the TCEQ Petroleum Storage Tank Program to track tanks holding regulated substances such as gasoline, diesel, kerosene, used oil, and aviation fuel. The form serves four distinct purposes: initial registration of a new tank, amendment of an existing registration, change of ownership, and annual self-certification of operational compliance. Each purpose triggers different attachments and different signature blocks, so the filer must check the correct box at the top of page 1.

Any owner or operator of a regulated underground storage tank (UST) with a capacity greater than 110 gallons that stores a regulated substance must file. Aboveground storage tanks (ASTs) must also register when they are located within 500 feet of a public drinking water supply well or inside the recharge zone of a major aquifer, under 30 TAC §334.123. Federally owned tanks, farm and residential motor fuel tanks under 1,100 gallons used for non-commercial purposes, and heating-oil tanks for on-site consumptive use are exempt.

The form must be filed within 30 days of tank installation, ownership change, or a substantive change in tank status. Self-certification is due annually, and the deadline is printed on the renewal notice TCEQ mails to the listed contact. Operating an unregistered tank or selling fuel from a tank that lacks a current delivery certificate (red tag/green tag) is a violation of Texas Water Code §26.3467 and exposes the owner to administrative penalties, supplier delivery prohibitions, and loss of eligibility for the Petroleum Storage Tank State Lead Program.

Before You Start: Documents and Information You Need

Gathering the right paperwork before you open the form saves days of back-and-forth with the TCEQ Registration team. The agency uses Central Registry to match every tank to a Regulated Entity (the physical site) and a Customer (the legal owner), so missing IDs are the single most common cause of rejection. Use the Central Registry search tool before you fill out anything to confirm whether your site and owner already exist in the system.

Here is the pre-filing checklist every filer needs:

• Customer Number (CN) for the legal owner — if the owner does not yet have one, request it through Central Registry; without it, TCEQ cannot post fees to the correct account.
• Regulated Entity Number (RN) for the facility — each physical address gets one RN; using the wrong RN routes your filing to the wrong file and delays the delivery certificate.
• Facility ID (FID) number — a five- or six-digit number assigned to each PST site; new facilities receive one after first registration.
• Tank installation certifications from a licensed installer registered under 30 TAC §334.402 — without this, TCEQ will not issue a delivery certificate.
• Financial assurance evidence — insurance certificate, surety bond, letter of credit, or proof of participation in the Petroleum Storage Tank Financial Assurance program; missing FA is the second most common rejection reason.
• Class A, B, and C operator training certificates — required under 30 TAC §334.602; names and certificate numbers go directly on the form.
• Cathodic protection testing records — most recent 3-year survey for steel tanks or piping; without it, the self-certification line is incomplete.
• Release detection method documentation — automatic tank gauge printouts, statistical inventory reconciliation reports, or interstitial monitoring records covering the past 12 months.
• Deed, bill of sale, or assignment of registration when filing for a change of ownership — TCEQ needs proof that the new owner has authority to sign.
• Annual registration fee payment — between $25 and $100 per tank depending on capacity, payable by check or through ePay.

If any one of these items is missing, expect a deficiency letter and a 30-day window to cure. If you cannot cure within that window, TCEQ will mark the registration incomplete and notify fuel suppliers to halt deliveries to the site.

Where to Get the Form and How to Access It

The official PDF lives on the TCEQ PST Forms page and is titled TCEQ-0724 Petroleum Storage Tank Registration and Self-Certification (Rev. 03/2023). Always download a fresh copy each time you file because TCEQ updates the form to match rule changes; using an older revision can cause rejection if a field was renamed or a checkbox added. The PDF is fillable in Adobe Acrobat Reader, so you can type entries directly into the boxes before printing.

Electronic filing is available through the State of Texas Environmental Electronic Reporting System (STEERS) under the PST Registration and Self-Certification module. STEERS requires a free user account, an Electronic Reporting Agreement (ER Agreement) signed and mailed to TCEQ once, and authorization from the Customer to act on the company’s behalf. Once approved, STEERS pre-populates your RN, CN, and tank list each year, which cuts data-entry errors dramatically.

If you cannot file online, paper submittals go to: TCEQ, PST Registration Team, MC-130, P.O. Box 13087, Austin, TX 78711-3087. You can also email a scanned, signed PDF to PST_Registration@tceq.texas.gov or fax it to (512) 239-2444. The agency date-stamps based on the postmark for mail and the receipt timestamp for fax, email, and STEERS — keep that proof until your delivery certificate arrives.

Step-by-Step: How to Fill Out Form TCEQ-0724 Line by Line

The form has four parts: Part I – Customer and Regulated Entity Information, Part II – Tank-Specific Information, Part III – Operator and Financial Assurance, and Part IV – Certification and Signature. Work through them in order, and never skip a field — TCEQ scans the form with optical character recognition, and blank required fields trigger an automatic deficiency.

Box 1: Purpose of Submittal

This top-of-page checkbox tells TCEQ what action to take with your filing. The options are Initial Registration, Amendment, Change of Ownership, Change of Status, and Annual Self-Certification.

To answer it, check exactly one box. If two purposes apply (for example, a new owner who also wants to add a tank), file two separate forms or call the PST Registration help line at (512) 239-2160 before submitting.

Example: Maria Lopez, who just bought a 3-pump convenience store on FM 1960, checks Change of Ownership on her first filing and will check Annual Self-Certification on every filing after that.

Nuance: If you are taking a tank temporarily out of service for more than 90 days, check Change of Status and attach a memo describing the temporary closure plan under 30 TAC §334.54.

Common mistake and consequence: Filers who recently bought a station often check Initial Registration, which causes TCEQ to create a duplicate Facility ID and split the compliance history between two files. The consequence is a delayed delivery certificate and a manual merge that can take 6 to 8 weeks.

Misconception: Many filers believe self-certification is optional once a tank is registered. It is not — self-certification is an annual requirement under 30 TAC §334.8(d), and skipping it voids your delivery certificate.

Box 2: Customer Number (CN) and Legal Owner Name

This field identifies the legal entity that owns the tanks, not the operator and not the property landlord. Enter the 9-digit CN beginning with the letters CN, followed by the exact legal name as it appears on the Secretary of State filing.

To answer it, look up the CN in Central Registry by company name. If no CN exists, submit a Core Data Form (TCEQ-10400) first to create one.

Example: Lone Star Fuels LLC enters CN603214578 and LONE STAR FUELS LLC exactly as it appears on the company’s franchise tax record.

Nuance: A sole proprietor uses their personal legal name, not a DBA. The DBA goes on the Regulated Entity line instead.

Common mistake and consequence: Entering a parent company name when the subsidiary actually owns the tanks. TCEQ will bill the wrong CN, and unpaid fees on the correct CN will accrue late fees of 5% per month.

Misconception: Some filers think the CN follows the property. It does not — the CN follows the owner. When ownership changes, the new owner brings their own CN to the facility.

Box 3: Regulated Entity Number (RN) and Site Name

The RN identifies the physical site, including its street address, GPS coordinates, and county. Enter the 11-character RN beginning with RN and the site’s commonly known name (often the store brand and number).

To answer it, search Central Registry by address. If the site is brand new and has no RN, request one through STEERS Core Data before you start the PST form.

Example: Maria Lopez’s new store enters RN102345678 and VALERO 7421 — FM 1960 EAST.

Nuance: If the facility straddles two addresses (for example, a corner lot with two entrances), use the address printed on the most recent fire marshal permit.

Common mistake and consequence: Using the mailing address of corporate headquarters instead of the site address. This routes inspection correspondence to the wrong place, and a missed Notice of Violation becomes a default enforcement order.

Misconception: Filers assume the RN changes when ownership changes. It does not — the RN is permanently tied to the physical site, only the CN linked to it changes.

Box 4: Facility ID Number (FID)

The FID is the legacy PST identifier still used on delivery certificates and inspection reports. It is 5 or 6 digits with no letters.

To answer it, copy the FID from your most recent delivery certificate or from the upper-right corner of any prior TCEQ correspondence about the facility. New facilities leave this blank and TCEQ assigns one after processing.

Example: The FM 1960 Valero enters 0078432 as printed on the prior owner’s last delivery certificate.

Nuance: If you operate multiple sites under one CN, each site has its own FID, and mixing them up causes fee misallocation.

Common mistake and consequence: Writing the RN here instead of the FID. The form will route to manual review and add 2 to 4 weeks to processing.

Misconception: Some filers think the FID has been retired in favor of the RN. Both are still in use, and the form requires both.

Box 5: Site Address, City, County, ZIP

Enter the physical street address (no P.O. boxes), city, county, and 5-digit ZIP code. Use the address that emergency responders would use to find the tanks.

To answer it, type the address in all capitals to match TCEQ’s database formatting: 7421 FM 1960 RD E, HUMBLE, HARRIS, 77346.

Example: Marcus Patel’s fleet yard enters 4500 NAVIGATION BLVD, HOUSTON, HARRIS, 77011.

Nuance: Rural sites without a 911 address must include both the legal description (abstract and survey) and the GPS latitude/longitude in decimal degrees.

Common mistake and consequence: Listing only the city without the county. TCEQ uses county to route inspections to the correct regional office, and missing county data delays inspection scheduling.

Misconception: Filers assume ZIP+4 is required. The standard 5-digit ZIP is sufficient.

Box 6: Site Contact Name, Phone, and Email

This is the person TCEQ will call or email about the registration, not the operator on duty. Enter a full name, a direct phone number, and a monitored email address.

To answer it, list someone who can answer compliance questions and authorize payment, typically the owner, store manager, or compliance consultant.

Example: Maria Lopez enters MARIA LOPEZ, (832) 555-0144, maria@lonestarfuels.com.

Nuance: If you use a compliance consultant, list both the consultant and the owner as contacts and attach a signed authorization letter so TCEQ can speak with the consultant.

Common mistake and consequence: Listing a generic store email like info@store.com that nobody monitors. Renewal notices go unanswered, the self-certification deadline slips, and the delivery certificate expires.

Misconception: People think the contact must be a Texas resident. It does not — any authorized representative works.

Box 7: Tank Number, Capacity, and Installation Date

Each tank gets its own row. Enter the tank’s on-site number (usually 1, 2, 3), its capacity in gallons, the installation date in MM/DD/YYYY format, and the substance stored.

To answer it, copy capacity and install date from the tank installation certification. Use the exact substance category: gasoline, diesel, kerosene, used oil, aviation fuel, or other regulated substance.

Example: Tank 1 = 12,000 gal, 04/15/2018, gasoline; Tank 2 = 10,000 gal, 04/15/2018, diesel.

Nuance: If a tank is compartmentalized (split internally to hold two products), list each compartment as a separate row with the same install date but different substances.

Common mistake and consequence: Reporting nominal capacity (the label) instead of the actual capacity from the manufacturer’s certification. TCEQ cross-checks against installer records, and a mismatch triggers a field inspection.

Misconception: Filers think they can list “miscellaneous petroleum” to avoid choosing a substance. The form requires a specific substance code, and “miscellaneous” is not accepted.

Box 8: Tank Construction and Corrosion Protection

For each tank, check the construction type: fiberglass, steel with cathodic protection, steel with internal lining, double-wall, or other. Then check the corrosion protection method.

To answer it, read the tank’s installation certification — the construction type is printed on the manufacturer’s nameplate.

Example: Tank 1 = fiberglass, double-wall, no cathodic protection required.

Nuance: Steel tanks installed before December 22, 1988 without cathodic protection must be upgraded or closed; if your tank fits this description, attach the upgrade certification.

Common mistake and consequence: Checking “double-wall” when only the tank is double-wall but the piping is single-wall. The form has separate boxes for tank wall and piping wall, and combining them voids the release-detection certification.

Misconception: Owners think fiberglass tanks need cathodic protection. They do not — fiberglass is non-corrodible.

Box 9: Piping Construction and Release Detection

Identify whether the piping is pressurized, suction (safe), suction (other), or gravity, then list the release detection method for both the tank and the piping.

To answer it, accepted methods for tanks include automatic tank gauging (ATG), statistical inventory reconciliation (SIR), interstitial monitoring, and manual tank gauging (small tanks only). Pressurized piping requires an automatic line leak detector plus annual line tightness testing or monthly monitoring.

Example: Tank 1 = ATG monthly; piping = pressurized, ALLD plus interstitial monitoring.

Nuance: Manual tank gauging is allowed only for tanks of 1,000 gallons or less and only as the sole method for tanks of 550 gallons or less.

Common mistake and consequence: Listing SIR without naming the vendor and certification. TCEQ requires a third-party certified SIR vendor under 30 TAC §334.50, and an uncertified vendor invalidates the release detection record.

Misconception: Filers think weekly visual inspection counts as release detection. It does not — it satisfies walkthrough inspection rules but not the monthly release detection rule.

Box 10: Spill, Overfill, and Secondary Containment

Confirm each tank has a spill bucket of at least 5 gallons, an overfill prevention device (automatic shutoff, ball float, or audible alarm), and where required, secondary containment under 30 TAC §334.51.

To answer it, check the device installed on each tank and write the device’s brand and model.

Example: Tank 1 = OPW 1-2100 spill bucket, automatic shutoff at 95%, double-wall secondary containment.

Nuance: Ball floats are no longer allowed as new installations after October 13, 2018, but existing ball floats can continue until replaced.

Common mistake and consequence: Checking “audible alarm” without identifying who monitors it. Alarms only count when staffed during delivery, and unattended alarms fail the overfill rule.

Misconception: Owners assume any spill bucket meets the rule. It must be tested for liquid tightness every 3 years or be double-walled with continuous interstitial monitoring.

Box 11: Class A, B, and C Operator Designations

List the name of at least one Class A (overall responsibility), one Class B (day-to-day compliance), and one Class C (first responder during emergencies) operator for each facility, along with each operator’s certification number and the training provider.

To answer it, copy names and certificate numbers from operator training cards issued by a TCEQ-approved training provider. One person may hold all three roles at a small facility.

Example: Class A: Maria Lopez, Cert #TX-A-44321, ICC; Class B: Maria Lopez, Cert #TX-B-44321, ICC; Class C: Carlos Mendez, Cert #TX-C-77890, ICC.

Nuance: A new Class C operator must be trained within 30 days of being assigned duties; do not leave the line blank during onboarding — list the prior Class C and update later.

Common mistake and consequence: Listing the same person as Class C for every shift. Class C must actually be on-site during operating hours, so a single Class C only works if the facility has one shift.

Misconception: Filers think operator training is one-time. Refresher training is required after a Notice of Violation involving operator error.

Box 12: Financial Assurance Mechanism

Identify how the owner demonstrates financial responsibility for cleanup of releases, as required by 30 TAC §334.108. Options include commercial insurance, surety bond, letter of credit, trust fund, self-insurance, or state assurance program participation.

To answer it, check the mechanism and write the policy or instrument number, the issuer, the per-occurrence limit, and the annual aggregate.

Example: Commercial insurance, Federated Mutual #PST-44213, $1,000,000 per occurrence, $2,000,000 aggregate.

Nuance: Owners with 100 or more tanks must show $1 million per occurrence and $2 million aggregate; owners with fewer tanks need $1 million per occurrence and $1 million aggregate.

Common mistake and consequence: Listing an insurance policy that excludes pre-existing contamination without disclosing it. TCEQ rejects coverage with hidden exclusions, and the tank becomes uninsured by rule.

Misconception: Owners think their general liability policy covers PST cleanup. It rarely does — PST coverage must be a dedicated pollution policy.

Box 13: Certification and Signature

The owner (or an authorized officer) signs and dates the form under penalty of perjury, certifying that all information is accurate and that the tanks meet applicable rules. Print the signer’s name, title, and the date in MM/DD/YYYY format directly below the signature line.

To answer it, only the legal owner, a corporate officer with signature authority, or an attorney-in-fact under a recorded power of attorney may sign. Consultants and store managers cannot sign unless named on a power of attorney filed with TCEQ.

Example: Maria Lopez, Managing Member, Lone Star Fuels LLC, 05/12/2026.

Nuance: Electronic signatures through STEERS satisfy this box only if the signer holds an active STEERS ER Agreement on file.

Common mistake and consequence: A store manager signs without authority. TCEQ voids the registration and requires resubmission, which can push the delivery certificate past the supplier deadline and cut off fuel deliveries.

Misconception: Filers think a typed name in the signature box counts. It does not on the paper form — the paper form requires an ink signature.

How to File the Completed Form

TCEQ accepts the completed Form TCEQ-0724 through four channels, and each channel has different processing times and proof-of-filing rules. Pick the channel that matches your deadline pressure and your tolerance for paperwork.

Online via STEERS. Log into STEERS, pick the PST module, submit the form electronically, and pay the annual fee through ePay. Processing usually takes 7 to 10 business days. STEERS gives you a confirmation number on screen and a follow-up email — save both as proof of filing.

By mail. Send the signed original to TCEQ, PST Registration Team, MC-130, P.O. Box 13087, Austin, TX 78711-3087 with a check made payable to TCEQ covering all per-tank fees. Processing takes 3 to 4 weeks from postmark. Use certified mail with return receipt as your proof of filing.

By email. Send a single PDF (signed and scanned) to PST_Registration@tceq.texas.gov. Pay fees separately through ePay and reference the facility’s FID in the subject line. Processing takes 2 to 3 weeks. Save the sent-mail receipt and any auto-acknowledgment.

By fax. Fax to (512) 239-2444 with a cover sheet listing the FID and contact info. Pay fees through ePay. Processing matches the email channel. Keep the fax confirmation page as proof.

Fees range from $25 per tank for tanks of 1,000 gallons or less to $100 per tank for tanks over 10,000 gallons, billed annually under 30 TAC §334.21. Late fees of 5% per month apply, and unpaid fees over 60 days trigger a delivery certificate hold.

What Happens After You File

Once TCEQ receives your form, the Registration Team checks it against Central Registry, verifies operator certifications, confirms the financial assurance mechanism is current, and confirms that fees are paid. If anything is missing, you receive a deficiency letter by email or mail with a 30-day cure window. If everything is in order, TCEQ issues a delivery certificate (commonly called the green tag) that authorizes fuel suppliers to deliver to the site.

The delivery certificate prints the FID, the site name and address, the owner’s CN, and the certificate’s expiration date. Post it where the delivery driver can see it from the fill port. Fuel suppliers are required under 30 TAC §334.5 to verify the certificate before each delivery, and they face penalties of up to $10,000 per delivery if they deliver to an uncertified site.

TCEQ inspects each PST facility on a risk-based schedule, typically every 1 to 3 years. If the inspector finds a violation, you receive a Notice of Violation (NOV) with a corrective action deadline. Failure to correct can escalate to an Agreed Order with administrative penalties, and repeat violations make the facility ineligible for the State Lead Program that covers cleanup costs for qualifying older releases.

Mistakes to Avoid When Filling Out the Form

These are the ten errors TCEQ flags most often in deficiency letters.

• Using an outdated form revision. TCEQ rejects forms with retired field names, costing 2 to 4 weeks in re-filing.
• Mixing up CN and RN. Fees post to the wrong account and the registration sits in limbo until a manual fix.
• Leaving the FID blank on an existing facility. Forces TCEQ to search by address, often creating a duplicate file.
• Listing nominal tank capacity instead of certified capacity. Triggers a field verification inspection.
• Naming a Class C operator who is not on-site during operating hours. Operator rule violation, automatic NOV.
• Listing an expired insurance policy as financial assurance. Tank is treated as uninsured from the policy expiration date forward.
• Letting a store manager sign without power of attorney. The form is void and must be re-filed with proper authority.
• Listing pressurized piping without an automatic line leak detector. Release-detection rule violation under §334.50.
• Forgetting to attach operator training certificates for new operators. Form is incomplete, and the deficiency clock starts.
• Paying fees to the wrong CN. Late fees accrue on the correct CN until manually corrected.

Do’s and Don’ts

These quick rules separate clean filings from rejected ones.

Do’s

• Download the current form revision from TCEQ before every filing because field names change between revisions.
• Look up the CN, RN, and FID in Central Registry before you start so every ID matches TCEQ records.
• Use all capital letters for names and addresses because Central Registry stores them that way and matches them in uppercase.
• Sign the paper form in blue or black ink because photocopied or stamped signatures get rejected as non-original.
• Pay fees through ePay even when filing on paper because ePay posts faster and gives you a digital receipt.
• Keep a complete photocopy of the signed form plus all attachments for 3 years because TCEQ may request it during inspection.

Don’ts

• Don’t use whiteout or cross-outs because TCEQ treats corrected fields as illegible and issues a deficiency.
• Don’t list a P.O. box as the site address because emergency responders cannot find tanks at a P.O. box.
• Don’t combine multiple facilities on one form because each RN gets its own form.
• Don’t list “TBD” or “pending” for operator names because incomplete operator fields fail the rule.
• Don’t sign before the form is fully completed because TCEQ treats a signed-blank form as fraud under §26.3475.
• Don’t wait until day 29 of a 30-day deadline to file because mail processing can push you over the deadline through no fault of your own.

Pros and Cons of Filing on Your Own vs. With Help

Many owners file Form TCEQ-0724 themselves, but consultants and compliance firms exist for a reason. Here is how the two paths compare.

Pros of filing on your own

• Lower cost because consultant fees of $300 to $1,200 per filing stay in your pocket.
• Faster decision-making because you don’t wait on a third party to schedule the work.
• Direct learning because you know your tanks and your IDs better after each filing.
• Direct relationship with TCEQ staff because the Registration Team prefers talking to the actual owner.
• Full control of timing because you decide when to file rather than waiting on a consultant’s queue.

Cons of filing on your own

• Higher error rate because first-time filers miss field-level requirements that consultants spot in seconds.
• Time cost because reading the rules and the form for the first time can eat 6 to 10 hours.
• Risk of missing a rule update because consultants track changes in 30 TAC Chapter 334 as part of their job.
• No backup at inspection time because consultants often handle the inspector walk-through too.
• Personal liability for misstatements because the owner signs under penalty of perjury and cannot blame staff.

FAQs

Do I need to file Form TCEQ-0724 if my tank only holds heating oil for my own building?

No. Heating-oil tanks used solely for on-site consumptive use are exempt under 30 TAC §334.3, regardless of size, so they do not require PST registration.

Do farm and residential motor fuel tanks require registration?

No. Farm or residential motor fuel tanks of 1,100 gallons or less used for non-commercial purposes are exempt and do not require Form TCEQ-0724.

Can I file Form TCEQ-0724 electronically?

Yes. TCEQ accepts electronic filings through the STEERS portal once you have a STEERS account and a signed Electronic Reporting Agreement on file with the agency.

Do I need a new RN when I buy an existing station?

No. The RN follows the site permanently, so you reuse the existing RN; only the Customer Number changes when ownership transfers.

In Box 2, do I list my DBA or my legal entity name?

No to the DBA. Box 2 requires the legal owner name as registered with the Texas Secretary of State; the DBA belongs on the site name line in Box 3.

In Box 7, do I list nominal capacity or certified capacity?

No to nominal capacity. Use the certified capacity from the manufacturer’s installation documentation because TCEQ cross-checks against installer records.

In Box 11, can one person serve as Class A, B, and C operator?

Yes. At a small single-shift facility, one trained person may hold all three operator roles, provided they are on-site during all operating hours.

In Box 12, can my general liability policy satisfy financial assurance?

No. General liability rarely covers pollution releases, so you need a dedicated pollution policy, surety bond, or state assurance program participation.

Is self-certification really required every year even if nothing changed?

Yes. Annual self-certification is required under 30 TAC §334.8(d) regardless of changes, and skipping it voids the delivery certificate.

Can a store manager sign the form for the owner?

No. Only the legal owner, a corporate officer, or an attorney-in-fact named in a recorded power of attorney may sign Form TCEQ-0724.

How long does TCEQ take to issue a delivery certificate?

Yes, there is a typical window — STEERS filings post within 7 to 10 business days, while mailed filings take 3 to 4 weeks from postmark to certificate issuance.

What happens if I keep selling fuel while my registration is in deficiency?

No, you cannot keep selling. Suppliers are barred from delivering, and continued operation carries penalties up to $10,000 per tank per day under Texas Water Code §26.3475.
