Abstract: Berm apparatus comprised of a plurality of berm members having a cross sectional configuration to limit the release of a substance into the environment. The berm members may include a footing member extending laterally from a first side of an upright member adjacent to a bottom end of the upright member. The berm members may also include a containment surface projecting from a second side of the upright member adjacent to a top end of the upright member. The containment structure may also project from adjacent the top end portion to a grade upon which the berm member rests. In this regard, the berm members may contribute to the structural integrity of the berm members, reducing the tendency of the berm member to slide or tip.
