ATCP 93.050(113)(a)(a) There is indication that a tank system or dispensing system has leaked — such as inventory losses; observable free product or evidence of free product in secondary containment at dispensers, submersible pumps or spill buckets; petroleum odors; unexplained presence of water in a tank; or activation of a leak detection alarm system — but there is no observable environmental evidence of a release. ATCP 93.050(113)(b)(b) There is observable environmental evidence of a release, such as soil discoloration or free product, but the source is unknown. ATCP 93.050 NoteNote: See sub. (62) for a definition of “leak,” sub. (76) for a definition of “obvious release” and sub. (103) for a definition of “release.”
ATCP 93.050(114)(114) “Tank” means a device designed to contain an accumulation of regulated substance and constructed of non-earthen materials such as concrete, steel, fiberglass or plastic, and including the following types of tanks, which have the following meanings: ATCP 93.050(114)(a)(a) “Abandoned tank” means an aboveground or underground tank with or without product that is not recognized by this chapter as in-use, temporarily out of service, or closed. ATCP 93.050(114)(b)(b) “Accumulator tank” or “accumulator reservoir” means a container that is integral to a closed-loop mechanical-system operation of equipment, and that is used either to provide a regulated substance on demand, such as a fluid that is used as a heating or cooling media, or to store a regulated substance that is displaced from the functioning equipment, such as from an elevator or hydraulic lift. ATCP 93.050 NoteNote: Accumulator tanks are outside the scope of this chapter.
ATCP 93.050(114)(c)(c) “Breakout tank” means a tank that is used to relieve surges in an oil pipeline system or to receive and store oil transported by a pipeline for reinjection and continued transportation by a pipeline. Tanks considered by this chapter to be breakout tanks do not have piping that transfers product directly to or from a loading rack. ATCP 93.050(114)(d)(d) “Day tank” means an intermediate tank in a product transfer system between a storage tank and the end use of the product, usually a generator. The purpose of a day tank is to provide immediate product to the end source where the supply may otherwise be influenced by product temperature, viscosity or inadequate supply pressure. ATCP 93.050(114)(e)(e) “Farm tank” means a tank that is constructed in accordance with NFPA 30A section 13.2 and installed on a farm premises. ATCP 93.050(114)(f)(f) “Field-erected tank” means an aboveground tank that is built on the site from sections and components. ATCP 93.050 NoteNote: See par. (p) for a definition of “fixed tank.”
ATCP 93.050(114)(g)(g) “Gravity tank” means a supply tank from which the product is delivered directly by gravity. ATCP 93.050(114)(h)(h) “Integral tank” means a vessel with a liquid capacity of less than 110 gallons, which supplies fuel to an engine and which is assembled and used with the engine as a single unit of equipment. ATCP 93.050 NoteNote: Vessels with a capacity of 110 gallons or more are included in the definition of storage tank in par. (q).
ATCP 93.050(114)(i)(i) “Movable tank” means an aboveground storage tank that meets all of the following: ATCP 93.050(114)(i)1.1. Has a liquid capacity of 110 gallons or more, and is used for storing and dispensing liquid motor vehicle fuel. ATCP 93.050(114)(i)2.2. Is supported on skids, wheels without axles, or similar means and is not mounted upon a tank vehicle or chassis capable of road travel. ATCP 93.050 NoteNote: Movable tanks are acceptable for use at construction projects, farms, and other locations recognized in subch. VI, where it is more practical to move the tank, typically by lifting equipment, to off-road motorized equipment for dispensing, rather than drive the motorized equipment to the tank.
ATCP 93.050(114)(j)(j) “Multi-compartment tank” or “multi-chamber tank” means a vessel that contains 2 or more compartments created by the presence of an interior wall so that 2 or more substances can be stored at the same time within a single tank shell. ATCP 93.050 NoteNote: In accordance with s. ATCP 93.250, each compartment of a multi-compartment tank is considered a separate tank, even if the same substance is stored in more than one compartment. ATCP 93.050(114)(k)(k) “Portable tank” means an aboveground closed vessel that has a liquid capacity of 110 gallons or more; is not otherwise defined in this chapter; is equipped with skids, mountings or accessories to facilitate handling of the tank by mechanical means; and is not intended for fixed installation or for highway vehicle fueling. “Portable tank” includes intermediate bulk containers. ATCP 93.050(114)(L)1.1. “Process tank” or “flow-through process tank” means a tank that forms an integral part of a production process through which there is a steady, variable, recurring, or intermittent flow of materials during the operation of the process and the tank is utilized to carry out or control the heating, cooling, mixing, blending, separating, metering, or chemical action of materials. The processing is done on a regular basis and it is the primary function of the tank. ATCP 93.050(114)(L)2.2. “Process tank” or “flow-through process tank” does not include a tank that is used for the storage of materials before their introduction into the production process or for the storage of finished products or by-products from the production process, or a tank that is only used to recirculate materials. A process tank would be considered a storage tank if the vessel is used as storage for a period exceeding 96 hours after the processing ends. ATCP 93.050 NoteNote: Process tanks are outside the scope of this chapter.
ATCP 93.050(114)(m)(m) “Product recovery tank” means a tank that forms an integral part of a ch. ATCP 93 regulated substance spill control system for a storage, processing or transfer area. The purpose of the tank is spill recovery and temporary containment. A product recovery tank does not include a tank that is used for the storage of materials or by-products from a flow-through reclamation process. A product recovery tank will be considered a storage tank if the vessel is used as storage for a period exceeding 96 hours after the control of a release or spill.
