Abstract
An above-ground oil storage tank with a valve and spill containment system. The tank comprises an internal secondary chamber which is readily accessible from the exterior. The secondary chamber houses an outlet valve and may also house sample taps, electronic level indicators and temperature gauges, keeping these components protected from the elements in a warm and dry environment. The secondary chamber also contains spills from the outlet valve and sample taps and may include means to conveniently recover spilled fluid. The tank may also include overflow control means which prevents overflow of fluid from the tank and directs such fluid into the secondary chamber, and loading means within the secondary chamber.
