Abstract
A spill containment system for storage tanks, flow devices, and the like, and a containment system for spilled light non-aqueous phase liquid are provided. The spill containment system comprises a liner for receiving and containing liquid that spills, as well as a withdrawal tube that sealingly extends into the liner at a high point thereof. An alternative spill containment system comprises two liner portions, one about a storage tank and another about a flow device leading, for example, to a furnace. A withdrawal tube extends to a low point of the first liner portion. The containment system comprises a trench, filled for example with low capillarity medium, for at least partially surrounding an area where light non-aqueous phase liquid is stored or may migrate to. A liner is disposed over the top of the trench and along at least a portion of one side thereof. At least one withdrawal tube sealingly extends through the liner at a high point thereof and into the trench.
