NR 468.30NR 468.30 Industrial process cooling towers. NR 468.30(1)(1) Applicability. The provisions of this section apply to the owners and operators of all new and existing industrial process cooling towers that are operated with chromium-based water treatment chemicals on or after September 8, 1994, and are either major sources or are integral parts of facilities that are major sources. NR 468.30(2)(2) Definitions. As used in this section, terms not defined in this subsection have the meanings given in ch. NR 400. In addition, the following definitions apply to the terms used in this section: NR 468.30(2)(a)(a) “Chromium-based water treatment chemicals” means any combination of chemical substances containing chromium used to treat water. NR 468.30(2)(b)(b) “Construction” means the onsite fabrication, erection or installation of an industrial process cooling tower. NR 468.30(2)(c)(c) “Cooling tower” means an open water recirculating device that uses fans or natural draft to draw or force air through the device to cool warm water by direct contact. NR 468.30(2)(d)(d) “Existing industrial process cooling tower” means any industrial process cooling tower on which construction or reconstruction commenced on or before August 12, 1993. NR 468.30(2)(e)(e) “Industrial process cooling tower” means any cooling tower that is used to remove heat that is produced as an input or output of a chemical or industrial process, as well as any cooling tower that cools a chemical or industrial process in combination with any heating, ventilation or air conditioning system. NR 468.30 NoteNote: Cooling towers that only cool heating, ventilation and air conditioning systems and that are operated with hexavalent chromium-based water treatment chemicals are regulated by 40 CFR 749.68. NR 468.30(2)(f)(f) “Initial startup” means the initiation of recirculation water flow within the cooling tower. NR 468.30(2)(g)(g) “Major source” means any stationary source, or group of stationary sources, that is located on one or more contiguous or adjacent properties and is under common control of the same person or persons under common control, that emits or has the potential to emit, in the aggregate, 10 tons per year (tpy) or more of any hazardous air pollutant which has been listed pursuant to section 112 (b) of the act (42 USC 7412 (b)) or 25 tpy or more of any combination of these hazardous air pollutants. NR 468.30(2)(h)(h) “New industrial process cooling tower” means any industrial process cooling tower on which construction or reconstruction commenced after August 12, 1993.
