UST Record Categories

Underground storage tank owners and operators are required to maintain records that pertain to their system. These records must be readily available to demonstrate compliance with state and federal regulations. There are several types of records owners and operators must keep.

1. Notifications

Includes records that should have been submitted to the regulating authority upon completion. Examples include installation documentation, notices of temporary closure, system compatibility forms, and notifications of spills or releases.

2. Release Detection

Tank release detection is generally ATG, SIR, or interstitial monitoring (IM). Line leak detection generally includes monthly electronic line leak testing or an annual 3rd party testing of the lines and leak detectors.

3. Corrosion Protection

Any records pertaining to cathodic protection, including testing, system certifications, or internal tank lining inspections.

5. Operator Training

All records pertaining to Class A, B, and C operator training, including certifications, emergency response procedures, and emergency contact information. Having response procedures and contact information posted in the proper location is included in this category.
