Note

Sections ATCP 93.610 (1) to (3) and 93.630 cover tank wagons, movable tanks, tank vehicles and aboveground farm tanks. Microsoft Windows NT 6.1.7601 Service Pack 1 Vehicle collision protection is required for tanks located outside or inside a building in motorized-vehicle or self-propelled-equipment traffic areas, where impact resulting from vehicle speed, turning or backing is a risk factor. For example, vehicle collision protection is required for tanks located adjacent to traffic areas that accommodate public and fleet fueling, service and delivery vehicles, self-propelled construction and service equipment, and forklift equipment. Microsoft Windows NT 6.1.7601 Service Pack 1 Vehicle collision protection is not required for tanks adjacent to vehicle and equipment service bays where traffic patterns and speed would not be expected to impact the tank system. Microsoft Windows NT 6.1.7601 Service Pack 1 Vehicle collision protection is generally not required at a terminal where roadways are clearly defined, access is restricted to authorized personnel, and vehicle drivers are familiar with the layout of the facilities. Microsoft Windows NT 6.1.7601 Service Pack 1 For many applications, the Department will accept either D.O.T. guardrails or 4-inch steel posts filled with concrete, set at least 3 feet into the ground and spaced no more than 4 feet on center.
