ATCP 93.350(2)(c)(c) Testing. All new tanks and pipe systems shall have pressure or vacuum testing that shall assure that all components and connections are tight, in a manner equivalent to the protocol and parameters specified in NFPA 30 section 21.5 and PEI RP 100 sections 11 and 14, before the tanks and pipe systems are placed into service. ATCP 93.350(2)(d)1.1. The qualified engineer responsible for design and oversight of construction of federally regulated hazardous substance liquid storage tank systems under this chapter shall meet the requirements of this paragraph. ATCP 93.350(2)(d)2.2. The qualified engineer shall be competent in the engineering methods for designing and installing hazardous liquid tank systems. ATCP 93.350(2)(d)3.3. The qualified engineer shall be a registered professional engineer, unless one of the exemptions in s. 443.14, Stats., applies. ATCP 93.350(3)(3) General requirements for tanks. Storage tanks shall meet all of the following requirements: ATCP 93.350(3)(a)(a) Structural. Tanks shall have a stable foundation under all operating conditions and be of sufficient structural strength to withstand normal handling and use. ATCP 93.350(3)(b)(b) Chemical compatibility. Tanks shall be chemically compatible with the substance being stored. ATCP 93.350(3)(c)(c) Wear, vibration, shock, and corrosion. Tanks shall be protected from failure due to internal and external wear, vibration, shock, and corrosion. ATCP 93.350(3)(d)(d) Fire, heat, vacuum, and pressure. Tanks shall be protected from fire, heat, vacuum, and pressure that might cause tank failure. ATCP 93.350(3)(e)(e) Collision protection. Tanks that are subject to vehicle collision shall be protected from collision damage by vehicles and equipment. ATCP 93.350(3)(f)(f) Fiberglass-reinforced plastic. If fiberglass-reinforced plastic material is used, the material shall be of sufficient density and strength to form a hard, impermeable shell that will not crack, wick, wear, soften, or separate under normal service conditions. ATCP 93.350(3)(g)(g) National standards. Tanks shall be designed, constructed and installed or certified by a qualified engineer in accordance with a standard recognized by the department that is developed by a nationally recognized association or independent testing laboratory. ATCP 93.350(3)(h)(h) Listing. Tanks used for underground storage shall be listed or shall be approved by the department. ATCP 93.350(3)(i)1.1. Used tank systems that do not meet the standards for new tanks under par. (g) or new piping under sub. (4) may not be reinstalled for hazardous substance storage. ATCP 93.350(3)(i)2.2. If a used tank meets the standards for new tanks under par. (g), it may be reinstalled provided it is certified by a qualified engineer for use. ATCP 93.350(3)(k)(k) Spill prevention at pumps and valves. The owner or operator shall prevent spills and leaks at all pumps and valves that control a liquid hazardous substance by using one or more of the following methods: ATCP 93.350(3)(k)1.1. Installation of seal-less pumps and valves, double-seal pumps and valves or equivalent technology. ATCP 93.350(3)(k)2.a.a. Implementation of a pump and valve inspection, maintenance, and repair program that complies with subd. 2. b. ATCP 93.350(3)(k)2.b.b. The frequency of inspection and scope of maintenance and repair shall be based on a minimum of 5 years of actual operating and service records, manufacturer’s recommendation, or records for similar operations. ATCP 93.350(3)(k)3.a.a. Installation of pumps and valves within a catchment basin, such as a drip pan, pad or secondary containment system, that complies with subd. 3. b. and c. ATCP 93.350(3)(k)3.b.b. The catchment basin shall be compatible with the substance stored for a period of time that will allow for cleanup under all operating conditions. ATCP 93.350(3)(k)3.c.c. The catchment basin shall be inspected each day of operation for accumulation of liquid and shall have the capacity to contain all spills likely to accumulate in the basin. ATCP 93.350(3)(L)(L) Tanks subject to melting. Aboveground storage tanks constructed of a material subject to melting when exposed to fire shall be located so that any spill or leak resulting from the failure of the material could not unduly expose persons, structures, or the environment. ATCP 93.350(3)(m)1.1. Storage tanks subject to scouring by the inflow of materials, or subject to wear from manual gauging shall be equipped with wear plates, diffusers, or other means to prevent localized wear or corrosion.
