ATCP 93.050 NoteNote: In a typical fueling island, the dispensing system, as defined in sub. (41), begins immediately downstream of the emergency shutoff valve, and all components upstream of that point, including the shutoff valve, are part of the tank system.
ATCP 93.050(116)(116) “Tank-system integrity assessment” or “TSIA” means the process by which the department seeks to determine if the integrity of a tank system or any component thereof has been compromised. This process includes precision tightness testing, inventory reconciliation, visual inspection of system components, and calibration checks of dispensers and automatic tank gauges. ATCP 93.050 NoteNote: In general, TSIAs are to be performed if there are indications that the integrity of a system has been compromised.
ATCP 93.050(117)(117) “Tank-system site assessment” or “TSSA” means the process by which the department expects tank-system owners or operators to determine if a tank system or any component of that system has released petroleum products or other hazardous substances into the soil, groundwater or surface waters. This process includes all of the following: ATCP 93.050(117)(a)(a) Observation of field conditions, such as stained soils; odors; pitting, holes or cracks in tank system components; observable leaks; and elevated in-field soil-gas readings. ATCP 93.050(117)(b)(b) Collection of soil samples for laboratory analysis of petroleum products or other hazardous substances, as prescribed in the department’s Tank System Assessment: A Guide to the Assessment and Reporting of Suspected or Obvious Releases From Underground and Aboveground Storage Tank Systems. ATCP 93.050(117)(c)(c) Reporting of the field observations and sampling results in a format prescribed by the department. ATCP 93.050 NoteNote: In general, TSSAs are to be performed at the time a storage tank system, or some component thereof, is to be permanently closed, upgraded or repaired, or if a change in service is to take place.
ATCP 93.050(118)(118) “Tank vehicle” means a tank truck or trailer system designed and constructed to comply with NFPA 385. ATCP 93.050 NoteNote: NFPA 385 recognizes 3 types of tank vehicles: (1) a tank truck in which the cargo tank is supported entirely on the truck chassis, (2) a tank semi-trailer in which the cargo tank is supported by both the truck chassis and trailer chassis, and (3) a tank full-trailer in which the cargo tank is supported entirely on the trailer chassis.
ATCP 93.050(119)(119) “Tank wagon” means a tank that is affixed to a trailer system with at least one axle, is constructed in accordance with s. ATCP 93.610 (1), has a liquid capacity of 1,100 gallons or less, and is used for storing and dispensing liquid motor vehicle fuel for equipment used on the site, or is used for storing other liquids regulated under this chapter. A tank wagon is not constructed to comply with NFPA 385. ATCP 93.050 NoteNote: Since a tank wagon is not designed and constructed under NFPA 385 criteria, it shall be towed empty on the road for transport and placement in accordance with s. ATCP 93.610 (1). ATCP 93.050(120)(120) “Temporarily out of service” or “TOS” means a storage tank system that is not in use meets the requirements of s. ATCP 93.445 (1) or 93.545 (1) and is intended to be placed back into use within 24 months. ATCP 93.050 NoteNote: Temporarily out of service does not apply to stationary tanks that are of seasonal use, such as heating fuel storage tanks.
ATCP 93.050(121)(121) “Transfer area” means the area where product is transferred, commonly referred to as loading or unloading, between a storage tank and a transport vehicle. Transfer areas are located at terminals, as well as at end-user and intermediate vendors in the product distribution stream. The transfer area may involve loading racks, pipe stands, or direct hose-to-valve connections, and accommodate top or bottom transfer. ATCP 93.050(121m)(121m) “Underground storage tank” or “underground tank” has the meaning given in sub. (122) unless the context requires otherwise. ATCP 93.050(122)(a)(a) “Underground storage tank system” or “UST system” means any one or combination of tanks, including connected pipes, that is used to contain an accumulation of regulated substances, and the volume of which, including the volume of connected underground pipes, is 10 percent or more beneath the surface of the ground. ATCP 93.050(122)(b)(b) “Underground storage tank system” or “UST system” does not include any of the following or pipes connected to any of the following: ATCP 93.050(122)(b)3.3. A liquid trap or associated gathering lines directly related to oil or gas production and gathering operations. ATCP 93.050(122)(b)4.4. A storage tank situated in an underground area, such as a basement, cellar, mine shaft or tunnel, if the storage tank is situated upon or above the surface of the floor and not surrounded by earth. ATCP 93.050(123)(123) “Upgrade” means the addition to or retrofit of some part of a storage tank system, such as cathodic protection, leak detection, lining, or spill and overfill controls, to improve the ability of a storage tank system to prevent the release of product. ATCP 93.050(124)(124) “Used oil” or “waste oil” means any oil refined from crude oil, or any synthetic oil, that has been used and as a result of such use is contaminated by physical or chemical impurities; and means used cooking oils that are used as fuel for purposes such as space heating or fueling motor vehicles. ATCP 93.050 NoteNote: See ch. NR 679 and s. 287.15, Stats., for other definitions of used oil and waste oil, and for requirements relating to those definitions, such as criteria for transporting or recycling these liquids. ATCP 93.050(125)(125) “Vehicle collision protection” means a structure or mechanism to protect a tank or system component from vehicle impact.
