Corrosion that is being described as the most aggressive and extensive ever known to permeate an Underground Storage Tank has been developing in recent years in diesel tanks through the country.
It is affecting steel as well as fiberglass tanks – attacking the metal components in the vapor space -- bungs, risers, caps, plugs, STP shafts, ball float assemblies and flapper valves.
Tanknology performed the fieldwork for this EPA study, using our TankCam® remote visual inspection system – the same system the EPA now recommends as a method for inspecting your diesel UST systems so that you know you're not among the 83 percent.
The TankCam video assessment does not require your tanks to be empty of fuel and it is performed remotely from aboveground – no one needs to enter your tank.
The inspection is highly detailed, as the technician captures high resolution images of all suspect conditions; corrosion or otherwise. The result is a digital video file, which details all the key components in the tank. The photos you see here were all captured in TankCam inspections.
