ATCP 33.20(5)
(5)
Prohibited materials; pesticide storage containers. ATCP 33.20(5)(a)(a) Pesticide storage containers and appurtenances may not be made of polyvinyl chloride unless they are used only to store sodium hypochlorite.
ATCP 33.20(5)(b)

ATCP 33.20(6)(a)
(a) Except as provided in par.
(b), storage containers shall be anchored to prevent flotation or instability that may result from liquid accumulation within a secondary containment structure. Anchors shall be independent of secondary containment structures and mixing and loading pads, except that anchor plates may be embedded in portland cement concrete floors of secondary containment structures if the anchor plates and the concrete floors are designed to withstand the flotation and wind stresses placed on them.
ATCP 33.20 Note
Note: Anchors located in soil outside the secondary containment structure do not place any added stress on the structure or its construction. It is possible to design anchor plates for the floors of a portland cement concrete secondary containment structure to withstand anchor stresses, but similar designs for walls are usually inadequate or cost-prohibitive.
ATCP 33.20(6)(b)1.
1. A storage container located in a secondary containment structure that complies with s.
ATCP 33.42, if it is the only storage container located in that secondary containment structure.
ATCP 33.20(7)(a)(a) Except as provided in par.
(b), an operator shall secure each storage container and its appurtenances by doing at least one of the following:
ATCP 33.20(7)(a)1.
1. Keeping the storage container and appurtenances in a locked building.
ATCP 33.20(7)(a)3.
3. Keeping the storage container and appurtenances in a locked outdoor enclosure that complies with par.
(c).
ATCP 33.20(7)(b)2.
2. The storage container and its appurtenances are empty and thoroughly cleaned. Thorough cleaning, in the case of a pesticide storage container and its appurtenances, means removal of pesticide residues from exterior surfaces and triple rinsing of interior surfaces. Triple rinsing of interior surfaces is not required if a manufacturer-installed device prevents the container from being opened.
ATCP 33.20(7)(c)
(c) An enclosure under par.
(a) 3. shall consist of a secure wall or fence that is at least 5 feet tall at every point, and free of gaps that could allow unauthorized persons to enter. Security fencing installed on a concrete secondary containment structure wall shall comply with chapter 2 of the
Wisconsin Minimum Design and Construction Standards for Concrete Mixing and Loading Pads and Secondary Containment Structures (February 2005), if the secondary containment structure is constructed after November 1, 2006.

Storage containers protected from moving vehicles. An operator shall protect storage containers and appurtenances against damage that may be caused by moving vehicles.
ATCP 33.20(9)
(9)
Filling storage containers. An operator may not fill a storage container to more than 95% of capacity unless the storage container is one of the following:
ATCP 33.20(9)(b)
(b) A mini–bulk container that is not filled beyond the maximum capacity shown on the container.
ATCP 33.20(10)(a)
(a) An operator shall label each fertilizer storage container, other than a mobile container, with the name or grade of fertilizer that it contains. Label contents shall be visible from outside the secondary containment structure in which the storage container is located.
ATCP 33.20(10)(b)
(b) An operator shall label each pesticide storage container in compliance with the federal insecticide, fungicide and rodenticide act as amended (
7 USC 136 to
136y) and regulations issued under that act. Label contents shall be visible from outside the secondary containment structure in which the storage container is located. The label on each pesticide storage container shall include the federal pesticide producing establishment number of the establishment that produced the pesticide. The label on a pesticide bulk sale container shall show the net contents of the container.
ATCP 33.20 Note
Note: A storage facility at which an operator repackages pesticide for sale or distribution from a storage container to mini–bulk or other containers is considered a “pesticide producing establishment" under the federal act. The operator of that storage facility must obtain a pesticide producing establishment number from the federal environmental protection agency, and must include that establishment number on every mini–bulk or other container filled at that storage facility. Mini-bulk containers must be properly labeled, regardless of whether they are mobile containers.
ATCP 33.20 Note
Whenever an operator sells pesticide from a storage container, the operator must supply the purchaser with the pesticide labeling required under ss.
94.676 and
94.70, Stats.
ATCP 33.20(11)
(11)
Venting pesticide storage containers. Every pesticide storage container, other than a mobile container or a container used only to store wood preservative, shall have a conservation vent that opens and closes within the designed pressure limits of the container to relieve excess pressure, prevent evaporative losses, and keep precipitation out of the container.
ATCP 33.20(12)
(12)
Underground storage prohibited. No person may store bulk liquid fertilizer, bulk liquid pesticide, or any material recovered under s.
ATCP 33.52, below ground level, except in a storage container that is located in a secondary containment structure.
ATCP 33.20(13)
(13)
Inspecting and maintaining storage containers. An operator shall, at least semi-annually, inspect and maintain each storage container and its appurtenances to minimize the risk of a discharge. Whenever an operator repairs a storage container, the operator shall make the repair according to good engineering practice and manufacturer specifications. An operator shall remove a storage container from service if it cannot be adequately maintained.
