ATCP 33.20(1)(c)(c) Materials used to construct or repair storage containers and appurtenances may not react chemically or electrolytically with stored fertilizer or pesticide in a way that may weaken the storage container or appurtenance, create a risk of discharge, or adulterate the fertilizer or pesticide.
ATCP 33.20(1)(d)(d) Metals used for storage container valves, fittings or repairs shall be compatible with other metals in the storage container, so that the combination of metals does not cause corrosion or electrolytic reactions that may weaken the storage container or its appurtenances, or create a risk of discharge.
ATCP 33.20(1)(e)(e) Storage containers and appurtenances shall be designed, constructed and maintained to hold fertilizer or pesticide of the highest specific gravity that may be stored in the containers.
ATCP 33.20(1)(f)(f) Bladder tanks, tank-in-tanks and field-erected storage containers shall be all of the following:
ATCP 33.20(1)(f)1.1. Designed and constructed according to API 650, and certified for compliance by the manufacturer, if the structure is installed, constructed or substantially altered after November 1, 2006. API 650 calculations shall be based on the highest specific gravity of fertilizer or pesticide that may be stored in the container.
ATCP 33.20(1)(f)2.2. Inspected before use, and at least once every 5 years during use, by an API 653-certified inspector for compliance with API 653. The storage container shall be inspected more frequently if recommended by an API 653-certified inspector. API 653 calculations shall be based on the highest specific gravity of fertilizer or pesticide that may be stored in the container.
ATCP 33.20(1)(f)3.3. Repaired, when necessary, according to API 653 and the recommendations of an API 653-certified inspector.
ATCP 33.20 NoteNote: Copies of API 650 and 653 are on file with the department and the legislative reference bureau. Copies may be purchased from the American Petroleum Institute at 1220 L Street NW, Washington DC 20005-4070, telephone (202) 682-8000, or the following web address: www.api.org.

ATCP 33.20(2)(b)(b) On pesticide storage containers other than mini-bulk containers or containers used to store sodium hypochlorite, all wetted parts inside shutoff valves and all connections between storage containers and shutoff valves shall be made of stainless steel.
ATCP 33.20 NoteNote: The department may grant a variance authorizing alternative materials that provide equivalent protection for waters of the state. See s. ATCP 33.02.
ATCP 33.20(2)(c)(c) Pipes, fittings and other appurtenances shall be permanently supported to prevent sagging and breakage that may be caused by gravity, vibration or other forces that may be encountered in the ordinary course of operations. To prevent sagging and breakage, piping and its supports shall be able to support 250 pounds.

The operator shall maintain the appurtenances as necessary, to keep them pressure-tight, and shall keep a written record of the pressure test results.
ATCP 33.20(2)(d)2.2. Inspect and test, for liquid-tightness, every joint through which a pipe extends through a secondary containment structure.
ATCP 33.20(2)(e)(e) An appurtenance may not be installed below ground, within or beneath a mixing and loading pad, within or beneath a secondary containment structure, or through any wall or floor of a secondary containment structure, on or after November 1, 2006.
ATCP 33.20(2)(f)(f) Piping connections shall be one of the following:
ATCP 33.20(2)(f)1.1. Threaded, welded, fused or permanently band-clamped.
ATCP 33.20(2)(f)2.2. Located over a mixing and loading pad that complies with s. ATCP 33.30.
ATCP 33.20(2)(f)3.3. Located within a secondary containment structure that complies with s. ATCP 33.42.
ATCP 33.20(3)(3)Liquid level gauging devices.
ATCP 33.20(3)(a)(a) If a storage container is equipped with a liquid level gauging device, the device shall be designed for safe and reliable use.
