ATCP 93.430(1)(1) Permanent vehicle collision protection shall be provided for any new or existing tank or system component that could result in a release of product when damaged, in any area where impact due to speed, turning, or backing of any type of motorized or self-propelled vehicle is likely to occur, except for tanks covered in ss. ATCP 93.610 (1) to (3) and 93.630.

ATCP 93.430 NoteNote: Sections ATCP 93.610 (1) to (3) and 93.630 cover tank wagons, movable tanks, tank vehicles, and aboveground farm tanks.

ATCP 93.430 NoteNote: 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.

ATCP 93.430 NoteVehicle 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.

ATCP 93.430 NoteVehicle 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.

ATCP 93.430(2)(2) At least 24 inches of clearance shall be provided between a vehicle impact barrier and the tank or system component to be protected.

ATCP 93.430(3)(3) Impact barriers shall be designed to protect the tank or component from impact damage by the force of the largest vehicle routinely in the traffic area traveling at 5 miles per hour or at the average traveling speed, if higher than 5 miles per hour, except as provided in sub. (4).

ATCP 93.430(4)(a)(a) For impact barriers designed primarily to protect from the impact of automobiles, the portion determined to be most vulnerable to vehicle impact shall be capable of withstanding a single impact of 12,000-lb force applied at 10 miles per hour or equivalent impact energy.

ATCP 93.430(4)(b)(b) The impact shall be applied using a minimum 0.5-inch thick steel plate having a frontal surface area of 12 inches by 12 inches centered at 18 inches above grade.

ATCP 93.430 NoteNote: 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.

ATCP 93.440(1)(1) Application. All new and existing aboveground storage tanks shall be inspected in accordance with this section.
