Easy UST Compliance Check

Corrosion Protection

All tanks and piping must be protected from corrosion, but USTs installed before December 22, 1988 can use some retrofit approaches not allowed for USTs installed on or after December 22, 1988. Be sure you know the corrosion protection requirements for each of your USTs.

For tanks:

• Tank is fiberglass?
• Tank is coated and cathodically protected steel?
• Tank is steel clad (or jacketed) with noncorrodible material?
• Tank retrofitted with cathodic protection?
• Tank retrofitted with interior lining?

Specify any other method used to achieve tank’s corrosion protection.

For piping:

Records for Cathodic Protection

• If you have impressed current systems or sacrificial anodes, you have the documentation of the last two inspection results conducted by a qualified cathodic protection tester within 6 months of installation, at least every 3 years thereafter, and within 6 months of a repair?

• If you have an impressed current system, you have documentation of the last three rectifier readings that need to be taken every 60 days to show that the rectifier is working properly? (Most USTs will share one rectifier.)

Spill Protection

All USTs must be protected from spills by having devices such as “spill buckets” or catchment basins that can contain spilled product.

• UST has spill protection equipment, such as catchment basin?

Overfill Protection

All USTs must be protected from overfills by using such devices as automatic shutoff devices, overfill alarms, or ball float valves.

• UST has automatic shutoff device?
• UST has overfill alarm?
• UST has ball float valve?

Other Requirements

• You keep records of all UST system repairs for the operating life of the UST system?

• If you have temporarily closed any USTs, you satisfy the requirements for temporary closure?
• You have evidence of “Financial Responsibility”?

Please note that filling out this checklist does not guarantee that you are in fact in compliance with UST requirements. Only an official site inspection can confirm your compliance status. Be sure to check with State/local agencies that may have additional/different requirements or their own checklists.
