ATCP 92.30(2)(2) Master construction plan. Instead of filing a separate construction plan with each permit application under sub. (1), an applicant may file a master construction plan which applies to 2 or more applications, and may refer to that master plan in each individual application. If a proposed installation or relocation entails any deviation from the master plan, the individual permit application shall clearly describe every deviation.

ATCP 92.30(3)(3) Vehicle and livestock scales; construction standards. Except as provided under sub. (6) or (9), every vehicle scale and every livestock scale shall comply with the following construction standards:

ATCP 92.30(3)(a)(a) Load–bearing piers. The main load–bearing piers supporting a scale shall be constructed of reinforced concrete. The main load–bearing piers shall be poured so that they are monolithic with the scale walls, or shall be tied to the walls with 1/2 inch (1.2 cm) reinforcing rods.

ATCP 92.30(3)(b)(b) Scale walls.

ATCP 92.30(3)(b)1.1. The walls of every scale shall be constructed of reinforced concrete. The side walls of every scale, other than a livestock scale constructed prior to January 1, 1992, shall be not less than 12 inches (30 cm) thick. The end walls of every scale shall be not less than 16 inches (40 cm) thick, except that end walls of a livestock scale or above–ground scale shall be not less than 12 inches thick.

ATCP 92.30(3)(b)3.3. A vehicle scale end wall, if poured with seams or joints, shall be constructed with a step at the outer edge to provide support for the vehicle approach slab unless the approach slab consists of reinforced concrete which is poured monolithically with the end wall and joined to the end wall with reinforcing rods. The step shall extend for the entire length of the end wall, and shall be at least 6 inches (15 cm) wide and 6 inches (15 cm) deep.

ATCP 92.30(3)(c)(c) Foundations.

ATCP 92.30(3)(c)1.1. Load-bearing piers and scale walls shall rest on reinforced concrete footings which extend at least 12 inches (30 cm) below the frost line, or on a reinforced concrete base slab not less than 12 inches (30 cm) thick. Footings and slabs which support load-bearing piers or scale walls shall be constructed according to the manufacturer’s engineering drawings, and shall be constructed to prevent frost heaving.

ATCP 92.30(3)(c)2.2. Scale pit floors and surfaces underlying above–ground vehicle scales shall be constructed of concrete, and shall be constructed so that they are well drained. The concrete floor or surface shall extend the full length and width of the scale. This subdivision does not apply to above-ground scales constructed prior to January 1, 1992.

ATCP 92.30(3)(c)3.3. A load-bearing concrete surface underlying an above-ground vehicle scale shall rest on a bed of compacted aggregate which is at least 6 inches (15 cm) thick under every portion of the load-bearing concrete surface, or on an alternative foundation constructed according to the manufacturer’s engineering drawings. This subdivision does not apply to above-ground scales installed prior to January 1, 1992.

ATCP 92.30(3)(d)(d) Top edge of scale wall. The top inside edge of every scale wall shall be framed, for its entire length, with a structural steel angle iron coping. The angle iron shall be at least 2 inches (5 cm) by 2 inches (5 cm) by 1/4 inch (.6 cm), and shall be constructed with welded projections so that it can be anchored in the concrete at approximately 4 foot (1.2 meter) intervals.

ATCP 92.30(3)(e)(e) Clearances around scales.

ATCP 92.30(3)(e)1.1. In every scale pit, there shall be a clearance of not less than 6 feet (1.8 meters) between the finished floor line of the scale pit and the top edge of the pit coping, or a clearance of not less than 48 inches (1.2 meters) between the finished floor line of the scale pit and the bottom of the load receiving element, the bottom of the beam supporting the load receiving element, or the top of the fully electronic load receiving element. The clearance between the load receiving element and the coping of every scale pit wall shall be not less than 1/2 inch (1.2 cm) and not more than 3/4 inch (1.8 cm).

ATCP 92.30(3)(e)2.2. In every above-ground vehicle scale, there shall be a clearance of not less than 6 inches (15 cm) between the top surface of the base slab and the bottom of the load receiving element. This subdivision does not apply to above-ground scales constructed prior to January 1, 1992.

ATCP 92.30(3)(e)3.3. In a scale pit containing a lever–type weighing element, there shall be a clearance of at least 27 inches (70 cm) on one side of the transverse lever between the transverse lever and the pit neck wall.

ATCP 92.30(3)(f)(f) Mechanical indicating elements; support. Mechanical indicating elements, including weigh beams and dials, shall be placed on reinforced concrete footings or metal structural members which are sufficiently strong to prevent deflection.

ATCP 92.30(3)(g)(g) Scale pit entrance. Every scale pit shall include an entrance through which persons may enter the scale pit. The entrance shall take one of the following forms:

ATCP 92.30(3)(g)3.3. An opening in the pit wall, not less than 36 inches (90 cm) wide. The top of the opening shall be no lower than the bottom of the weigh bridge, and the bottom of the opening shall be approximately even with the pit floor.

ATCP 92.30(3)(h)(h) Approach surfaces. Entry and exit approaches to a vehicle scale shall be at least as wide as the scale platform and at least 1/2 the length of the scale platform. Where it meets the end wall of a scale, each approach shall be supported on a step in the top of the end wall as provided under par. (b). Extending for the first 10 feet from the scale, each approach surface shall be on the same plane with the scale platform and shall be constructed of reinforced concrete, compacted asphaltic materials, steel grating, or structural steel plate of sufficient strength to withstand all loads equal to the concentrated load capacity of the scale. The remainder of the approach surface shall be constructed of a durable material and shall have a slope of not more than 1:12 (vertical rise/horizontal run). The approach shall be constructed and maintained to drain away from the scale, to provide easy vehicle access to the scale, and to provide easy access by the department or a scale service company to test compliance with s. ATCP 92.02 (1).

ATCP 92.30(3)(i)(i) Livestock scales; test weight unloading platform. A concrete test weight unloading platform shall be constructed and maintained next to every livestock scale. The test weight unloading platform shall be at least 10 feet (3 meters) long and 8 feet (2.4 meters) wide. The test weight unloading platform shall be on the same level and plane as the scale platform. The test weight unloading platform shall be situated so that a test truck can easily lower test weights onto the test weight unloading platform, and so that test weights can easily be moved from the test weight unloading platform to the scale platform.

ATCP 92.30(4)(4) Vehicle and livestock scales; tolerances. Vehicle and livestock scales installed or relocated under sub. (1) shall comply with acceptance tolerances under s. ATCP 92.02 throughout the period starting with the first date of use and ending 90 days after the department first receives notice under sub. (5) that the scale is in use. After that initial period, the scale shall comply with applicable tolerances under s. ATCP 92.02.

ATCP 92.30(5)(5) Vehicle and livestock scales; installation report. If a person installs or relocates a vehicle or livestock scale, that person shall report the completed installation or relocation to the department within 5 days after the installation or relocation is completed. The report shall be filed in writing and shall include all of the following:
