ATCP 33.32(8) (8) Pumping liquid products from rail cars. Section ATCP 33.30 and subs. (1) through (7) do not apply to the pumping of liquid bulk fertilizer or liquid bulk pesticide from a rail car to a storage container, provided that all of the following apply:

ATCP 33.32(8)(a) (a) The hose or pipeline from the rail car outlet valve to the pump is equipped with a shut-off valve, unless the pump can draw from no other hose or pipeline.

ATCP 33.32(8)(b) (b) The hose or pipeline from the pump to the storage container is equipped with an automatic check valve to prevent back flow. The check valve shall be located as close to the pump effluent port as possible, consistent with good engineering practice.

ATCP 33.32(8)(c) (c) All of the following are located over one or more spill containment basins that comply with par. (d):

ATCP 33.32(8)(c)1. 1. The rail car outlet valve.

ATCP 33.32(8)(c)2. 2. The pump.

ATCP 33.32(8)(c)3. 3. Every valve or plumbing connection that is located between the rail car outlet valve and the storage container, unless the valve or plumbing connection is threaded, welded, fused or permanently band-clamped.

ATCP 33.32(8)(d) (d) Every containment basin under par. (c) is liquid-tight, and is constructed of durable rigid material that is chemically compatible with any liquid that may be discharged to it. The basin shall have a capacity of at least 75 gallons, or a capacity at least equal to the capacity of the appurtenances that may discharge to it, whichever is greater. A containment basin may be permanent or portable. The operator shall routinely inspect and maintain the basin to ensure compliance with this paragraph.

ATCP 33.32(8)(e) (e) If the operator pumps the fertilizer or pesticide from the rail car to another mobile container, the other mobile container is parked on a mixing and loading pad that complies with this section.

ATCP 33.32(9) (9) Loading liquid bulk pesticide into anhydrous ammonia nurse tank. Section ATCP 33.30 and subs. (1) through (7) do not apply to the loading of liquid bulk pesticide into an anhydrous ammonia nurse tank if all of the following apply:

ATCP 33.32(9)(a) (a) The operator loads the bulk pesticide from a storage container that is located over a mixing and loading pad that complies with this section, or over a secondary containment structure that complies with s. ATCP 33.42.

ATCP 33.32(9)(b) (b) The operator uses a positive displacement pump to transfer the pesticide to the anhydrous ammonia nurse tank. The pump shall be located over a mixing and loading pad that complies with this section, or over a secondary containment structure that complies with s. ATCP 33.42. The pump shall be rated to deliver no more than 3 gallons per minute at a pressure of no more than 250 psi. The pump shall be equipped for manual shutdown, in addition to automatic shutdown under par. (c) 2.

ATCP 33.32(9)(c) (c) The pump under par. (b) is equipped with electronic controls that do all of the following:

ATCP 33.32(9)(c)1. 1. Prevent pump operation until the operator manually pre-sets the pumping volume and engages a separate manual starter switch.

ATCP 33.32(9)(c)2. 2. Automatically stop the pump when the pre-set volume has been pumped.

ATCP 33.32(9)(d) (d) The hose from the pump to the anhydrous ammonia nurse tank meets all of the following requirements:

ATCP 33.32(9)(d)1. 1. It is no longer than 12 feet and has an inside diameter of not more than 1/2 inch.

ATCP 33.32(9)(d)2. 2. It has a rated operating pressure of at least 1,200 psi with a burst strength of at least 5,000 psi.

ATCP 33.32(9)(d)3. 3. It has a check valve near its nurse tank end, and a manually operated valve and coupling to connect it to the nurse tank.

ATCP 33.32(9)(e) (e) The operator tests the connection between the hose and nurse tank before loading pesticide into the nurse tank, to ensure that the connection does not leak.

ATCP 33.32 Note Note: The most common pesticide products loaded into anhydrous ammonia are nitrapyrin based products.

ATCP 33.32 History History: CR 05-108: cr. Register October 2006 No. 610, eff. 11-1-06; CR 14-047: am. (5) (a), r. (5) (b) Register May 2015 No. 713, eff. 6-1-15; renum. (5) (a) to (5) under s. 13.92 (4) (b) 1., Stats., Register May 2015 No. 6-1-15.

ATCP 33.34 ATCP 33.34 Mixing and loading pad for dry products. Except as provided in sub. (6), a mixing and loading pad used for dry fertilizer or pesticide shall comply with all of the following:

ATCP 33.34(1) (1) Conveyor containment. A mixing and loading pad shall extend beneath any conveyor used to load or unload dry bulk fertilizer or dry bulk pesticide, unless the conveyor is fully enclosed within a housing that contains all spillage from the conveyor.

ATCP 33.34 Note Note: Section ATCP 33.62 requires that the unloading chute or conveyor be equipped with a dust control system or device to further minimize the risk of discharge.

ATCP 33.34(2) (2) Portland cement or asphalt concrete construction. A mixing and loading pad shall be constructed of portland cement or asphalt concrete.

ATCP 33.34(3) (3) Structural capability. A mixing and loading pad shall be designed, constructed and maintained to withstand all foreseeable load conditions, including the filled weight of all vehicles, application equipment or other equipment that may be used or located on it.
