Used to construct embankments and foundations, earth usually is easy to move with scrapers or other types of earthmoving equipment. For example, sufficient land area must be identified near the excavation to provide for soil handling, and temporary haul roads must be routed around the changing excavation configuration, providing a stable surface for on-road dump trucks that bring them near the load-out area. 0000001742 00000 n There are no O&M costs incurred at the site after excavation is performed.

As they travel over the work area their horizontal cutting edge slices the dirt and collects it in their hopper to be carried across the site and placed where needed. Portable water treatment systems to manage stormwater at standard grading sites can be used in some cases, but often additional treatment must be performed, and discharge requirements must be met based on the site contaminants and receiving facility (typically storm drains or a publicly owned treatment works [POTW]).
