About this file
This document is a tank inspection and maintenance assessment report for a 501,000-gallon bolted GST (ground storage tank). The report identifies current conditions and provides specific recommendations for repairs and upgrades across multiple tank components.
Exterior and Structural Components: The tank's exterior coating is in good condition but requires cleaning via pressure washing with an antifungal solution. The shell ladder lacks a compliant cable-type safety climb device and requires installation of fall protection signage at its base. The primary roof hatch needs a Confined Space Entry sign and a locking device (to be provided by owner). The primary shell manway bolts show rust and require replacement with maintenance-free galvanized steel bolts. Foundation anchor bolts and nuts exhibit rust and require cleaning, tightening, tack welding, and repainting. The exposed concrete foundation shows cracking and spalling requiring cleaning, sealing or painting, and repair with commercial non-shrinking grout.
Interior Systems and Accessories: The tank contains excessive sediment buildup requiring emergency dry interior cleanout. Interior wet conditions and lack of heating necessitate installation of two open coil element (OCE) heaters with electrical work by others. The tank requires an anti-vortex plate on the suction line and sacrificial anodes for passive cathodic protection. Shell accessories need attention: the liquid level gauge requires adjustment, calibration, and lubrication; a thermometer must be installed; the PVC overflow pipe in poor condition must be replaced with a steel overflow system complete with standoffs, flapper valve, and screen; and a frost-proof drain valve with locking device (lock provided by owner) must be installed.
