Inspect valve exterior for corrosion and tightness of bolts. Repaint and retighten as required.

FREQUENCY: Quarterly.

A.2.1.6. Thermal and Pressure Relief: Thermal and pressure relief valves must be inspected for signs of leak-by. Inspect relief valves for leaks by visually inspecting downstream flow indicators (if installed) for flow. If no flow indicators are installed listen for possible leaks.

Verify thermal and pressure relief valve setting by consulting as-built and historical data.

Thermal and pressure relief valves must be validated for proper calibration by isolating the valve and using the test connection provided on the piping in conjunction with a hand pump and portable reservoir. The operating pressure must be checked against the set pressure listed on the

A2-3 stamped information plate attached to the valve. The operating pressure must be adjusted to the stamped set pressure if necessary

A.2.2.7. Filter/Strainer: Clean and inspect basket and strainer screen. The contractor shall replace filters in the water separator annually.

FREQUENCY: Annually or more.

A.2.2.8. Internally Mounted Level Alarms: Test level alarm switches by activating manual testing levers, if equipped. If alarms switches are not equipped with manual testing levers, adjust the level of fuel in the tank to the alarm points in order to test the alarm switches. If it is not feasible to adjust the level of the fuel in the tank to all of the alarm set points, remove the alarm switches from the tank and test the alarms externally. Reinstall alarm switches in the tank once testing is complete.

FREQUENCY: Annually.

A.2.2.9. Cathodic Protection: Conduct tests on each buried, in contact with the ground, or submerged UST and pipeline facility in its UST and pipeline system that is under cathodic protection to determine whether the protection is adequate.

FREQUENCY: At intervals not exceeding 15 months, but at least once each calendar year.

A.2.3. Piping.

A.2.3.1. Visual Inspection: Visually inspect piping and coatings for signs of corrosion or damage. Inspect flanges and gaskets. Inspect pipe supports to ensure pipe is properly supported without binding, mis-alignment, or tipping. Ensure insulating or sliding material between the supports and piping is securely fastened and not missing or deteriorated. Ensure contact points between support and pipe are not corroded. Inspect pipe support anchor bolts and grout for signs of cracking, corrosion, or missing fasteners. Conduct line walk in areas of petroleum fuel piping. Visually inspect leak detection systems installed on underground piping.
