ATCP 93.320 NoteNote: Stationary combustion engines under this section are commonly used to power emergency generators and pumps that provide fire protection. For requirements for storage tanks that are used to fuel stationary combustion engines at a farm premises or construction project, see s. ATCP 93.630. ATCP 93.320(1)(b)(b) Certified installer. Tank installation shall be performed or supervised by a certified installer. ATCP 93.320 NoteNote: See s. ATCP 93.100 (1) (b) 11. for criteria that can be used to exempt these tanks from plan review. ATCP 93.320(1)(c)1.1. Aboveground tanks with the fill point remote from the tank and all new and existing underground storage tanks shall have the fill point labeled with the type of fuel. ATCP 93.320(1)(c)2.2. Aboveground storage tanks shall have the tank labeled with the type of fuel. ATCP 93.320(1)(d)(d) Aboveground storage tank systems located in buildings. Aboveground storage tank systems located in buildings and used to store fuel for stationary combustion engines and gas turbines shall comply with NFPA 20 and 37 chapter 6, and the fill connection shall be located outside the building. ATCP 93.320(1)(e)1.1. Aboveground storage tank systems not located in a building and used to store fuel for stationary combustion engines and gas turbines shall comply with subch. IV and NFPA 20 and 37 chapter 6. ATCP 93.320(1)(e)2.2. Storage tanks under this section that are within an enclosure which does not have enough non-mechanical, open-louver area in the lower portion of the walls or doors to prevent hazardous build-up of vapors shall have vents terminating outside of the enclosure. Any vent terminating through the roof of the enclosure shall extend high enough to prevent snow or ice build-up from impacting the operation of the vent. ATCP 93.320(1)(f)(f) Underground storage tank systems. Underground storage tank systems used to store fuel for stationary combustion engines and gas turbines shall comply with subch. V and NFPA 37 chapter 6. ATCP 93.320(2)(2) Spill and overfill prevention. Spill and overfill prevention shall be provided in accordance with s. ATCP 93.410. ATCP 93.320(3)(3) Tank closure and general administrative requirements. ATCP 93.320 NoteNote: Sections ATCP 93.440 to 93.470 address inspections; seldom-used and temporarily out of service tanks; change in service to store a non-regulated substance; tank closures; tank system site assessments; and confirming and responding to leaks, spills, overfills and releases. ATCP 93.320 NoteNote: Sections ATCP 93.545 to 93.585 address seldom-used and temporarily out of service tanks; change in service to store a non-regulated substance; tank system closures; conditions indicating releases; tank system integrity assessments; tank system site assessments; and responding to leaks, spills, overfills and releases.

ATCP 93.330(1)(1) Application. This section applies to all converted tanks, whether new or existing. ATCP 93.330(2)(2) General installation and use. Converted tanks for the storage of flammable and combustible liquids shall be installed by a certified installer. ATCP 93.330(3)(a)(a) Low-pressure tanks and pressure vessels that are being converted to the storage of flammable or combustible liquids at atmospheric pressure shall meet the applicable tank storage requirements of this chapter, specific to the liquid stored. ATCP 93.330(3)(b)(b) Tank supports shall be capable of supporting a static load equal to at least 2 times the weight of the full tank. This capability shall be confirmed by engineering structural analysis, by field testing, or by reference to an approved design standard. ATCP 93.330(4)(a)(a) The cargo tank of a tank vehicle that is converted to a stationary tank for the storage of flammable or combustible liquids shall meet the applicable tank storage requirements of this chapter, specific to the liquid stored, along with the requirements in pars. (b) to (d). ATCP 93.330(4)(b)(b) Cargo tanks for permanent stationary use shall be constructed of steel only.
