SELF CONTAINTAINED ABOVEGROUND TANKS www.SCAT-Tank.com   (SCAT) system will catch and hold the recovered contents of a stroage bleadder if it leaks or ruptures. SCAT tanks can be used for ground fuels storage and for special fuels such as JPTS, aviation gasoline (AVGAS) Jet A for unmanned aerial vehicle operations. The containment structure also serves to collect and hold fuel that might overflow while filling the storage tank. These 4,000 gallon SCAT tanks are designed to act as a secondary spill containment system for captureing fuel in the event the primary storage system (50- to 210,000-gallon bladders) collapses. Secondary containment facilities may contain single or multiple storage tanks. A secondary containment system should be constructed so spills do not escape to ground or surface waters before cleanup. The key is the ability to contain large spills, as well as leaks.
