An apparatus for storing or transporting flowable materials or other materials, such as diesel fuel, includes a container and a support. The container is supported by the support. The support sits on or is mounted across an upper part of an open top wagon or vehicle, such as a railway wagon or truck or trailer used for transporting bulk commodities. The apparatus is movable between an expanded configuration in which the container is expandable into a lower part of the wagon or vehicle and a collapsed configuration in which the container is collapsible to the support. The weight of the support and the container is borne by the upper part of the wagon or vehicle when the container is in its collapsed configuration and the apparatus is positioned on the wagon or vehicle.

An improved decontamination structure may feature at least two parallel rings with pillar supports therebetween and a plurality of containment bags draped thereon. Various clipping and support mechanisms may be utilized.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

In accordance with presently disclosed embodiments, a stackable bulk material storage container is provided. The bulk material storage container includes a frame having a top portion and a bottom portion, which is supported by a plurality of rigid bars. A semi-rigid containment structure is further provided, which is supported by the frame. The semi-rigid containment structure may be formed of a plurality of interconnected or attached panels of thin steel sheets, carbon graphite or fiber reinforced plastic. Alternatively, the semi-rigid containment structure may be integrally formed of a roto-molded plastic material. The frame optionally has an opening at the top, which is sized to allow for easy removal and replacement of the semi-rigid containment structure.
