The tank operator should preform periodic walk-around inspections to identify and repair areas of damage to the vessel or the coating itself and check for proper drainage around the tank area. It is imperative that the tank exterior be inspected periodically to ensure that the integrity of the coating is maintained. The frequency of periodic repainting will be based upon environmental factors in the geographic area where the tank is located. Special consideration should be given to the selected of the paint, surface preparation and coating application. The coating selected should be suitable for use with the current coating, or the existing coating should ne removed. The coating selected should be of industrial quality Proper site preparation and maintenance are vital to ensure drainage of surface water. Should ground conditions change or settlement occur, take the appropriate steps to maintain proper drainage and prevent standing water near or under the tank area. For diked tanks, remove any product spills immediately. Be sure to dispose of hazardous material properly. For diked tanks fitted with a drain, drain off water only. Drain openings are required to be maintained liquid tight. The primary tank shall be inspected monthly for the presence of water at the lowest possible points inside the primary tank.

The hazards associated with the cleaning, entry, inspection, testing, maintenance or other aspects of AST’s are significant. Safety considerations and controls should be established prior to undertaking physical activities associated with ASTs . Cleaning of tanks must be per state and local jurisdiction requirements. Refer to the STI Standard SP001, “Standard for the Inspection of Aboveground Storage Tanks” for requirements concerning tank inspections.
