See 30 TAC Chapter 334 (USTs and ASTs) for rules on regulation.

Underground Storage Tanks (USTs)

If you own one or more regulated underground storage tanks (USTs), then you must:

• Register each UST with the TCEQ — even if it is empty or unused.
• Each year, renew the delivery certificate for your facility at least 30 days before the current certificate expires.
• Include proof of Financial Assurance with all Self-Certification forms.
• Make sure that each UST tank fill pipe is clearly labeled according to the uniform system described in the rules [Subparagraph 334.8(c)(5)(C)].
• Have all facility fees billed to date to the current owner paid in full. Beginning September 1, 2007, Petroleum Storage Tank owners will no longer be assessed annual registration fees. Any fee that required payment prior to September 1, 2007 will continue to be the responsibility of the tank owner. This includes fees for tanks that were not properly registered by September 1, 2007.
• At least 30 days before beginning construction work on your UST facility, notify the TCEQ.
• Within 30 days of any changes in ownership at your UST facility, inform the TCEQ that the change has occurred.
• Any other changes need to be submitted within 30 days by using the Underground Storage Tank Registration and Self-Certification form (TCEQ-0724).

Aboveground Storage Tanks (ASTs)

Regulated aboveground storage tanks (ASTs) contain petroleum products. Only ASTs with a capacity greater than 1,100 gallons are regulated.

Petroleum product is a petroleum substance capable of being used as a motor fuel [Subparagraph 334.2(78)].

ASTs do not require financial assurance.

If you own one or more regulated aboveground storage tanks, then you must:

• Register each AST with the TCEQ — even if it is empty or unused. (Please note: the Tank Installation Date is when petroleum product was initially placed into the AST.)
• Have all facility fees billed to date to the current owner paid in full. Beginning September 1, 2007, Petroleum Storage Tank owners will no longer be assessed annual registration fees. Any fee that required payment prior to September 1, 2007 will continue to be the responsibility of the tank owner. This includes fees for tanks that were not properly registered by September 1, 2007.
• At least 30 days before beginning work on your ASTs, notify the TCEQ.
• Comply with installation requirements on the Edwards Aquifer.
• Within 30 days of any changes at your AST facility, submit notification of the change
