NR 419 to 425, or a VOC RACT variance approved under s. NR 436.05, if the change does not cause or exacerbate the violation of an ambient air quality standard or ambient air increment for any air contaminant other than ozone.(c)Resumption of operation.1. The resumption of operation of a source after a period of closure if the existing equipment was continuously included in the department's emissions inventory as an existing source covered by plans submitted under s. 285.11(6), Stats.2. The resumption of operation of a source after a period of closure if the source was never included and never required to be included in the emissions inventory as an existing source covered by plans submitted under s. 285.11(6), Stats., and the resumption of operation of the source will not cause or exacerbate the violation of an ambient air quality standard or an ambient air increment, will not result in the emission of a new air contaminant and is not prohibited by any permit, plan approval or special order applicable to the source.(d)Increase in production rate. An increase in production rate if: 1. The increased production rate does not exceed the design capacity of the source.2. The production rate increase does not require any change to existing equipment.3. The increase is not prohibited by any permit, plan approval or special order applicable to the source.4. The increase will not cause or exacerbate the violation of an ambient air quality standard or ambient air increment or violate an emission limit.(e)Increase in hours of operation. An increase in hours of operation if: 1. The increase is not prohibited by any permit, plan approval or special order applicable to the source.2. The increase will not cause or exacerbate the violation of an ambient air quality standard or ambient air increment or violate an emission limit.3. The change is not subject to an emission limitation or emission standard under section 111 or 112 of the Act (42 USC 7411 or 7412), excluding section 112 (d) (5) or (r) (42 USC 7412(d) (5) or (r)).(f)Change of ownership. A change in ownership of a source.(g)Routine maintenance or repair. The routine maintenance or repair of a source.(h)Change to process lines emitting VOCs. A change in a method of operation of a process line subject to s. NR 424.03(2) (c) that meets all of the following criteria: 1. The change does not result in annual potential VOC emissions from the process line which exceed the currently allowed annual potential VOC emissions based on conditions established under s. NR 424.03(2) (c).2. The change for the process line does not trigger a requirement under section 111 or 112 of the Act (42 USC 7411 or 7412), excluding section 112 (d) (5) or (r) (42 USC 7412(d) (5) or (r)). Note: The permittee shall continue to comply with the conditions established under s. NR 424.03(2) (c) in its construction or operation permit until the permit is revised.
(i)Change to use a clean fuel. A change to an external combustion furnace to allow for the combustion of a clean fuel that meets all of the following requirements: 1. The external combustion furnace has a maximum heat input capacity of no greater than 10 mmBtu/hour if the ability to combust distillate oil is being added and 25 mmBtu/hour if the ability to combust natural gas or propane is being added.2. The use of the new fuel does not cause or exacerbate the exceedance of any ambient air quality standard or increment in ch. NR 404.3. The change does not trigger a requirement under section 111 or 112 of the Act (42 USC 7411 or 7412), excluding section 112 (d) (5) or (r) (42 USC 7412(d) (5) or (r)).(j)Other changes. A change where all of the following conditions are met: 1. The change is not prohibited by any permit, plan approval or special order applicable to the source.2. The change is exempt under sub. (1), or the increased emissions due to the change do not exceed the maximum theoretical emission levels specified in sub. (2) (b), (c), (cm), (cs), (d) and (f). 3. The change does not trigger a requirement under section 111 or 112 of the Act (42 USC 7411 or 7412), excluding section 112 (d) (5) or (r) (42 USC 7412(d) (5) or (r)).(5) Exempt relocations. (a) In addition to the approved relocated sources which are exempt from the need for an additional permit under s. 285.60(5), Stats., and the relocation of an emissions unit within the contiguous property of an attainment area major source, no construction permit is required for the relocation of an emissions unit within the contiguous property of a minor source or a nonattainment area major source if all of the following conditions are met: 1. The relocation of the emissions unit is not prohibited by any permit, plan approval or special order applicable to the source.2. The emissions unit will not be modified.3. The emissions unit meets all applicable emission limitations.4. The emissions unit's stack height or stack gas exit velocity or temperature will not be decreased.(b) If the criteria in par. (a) 1., 2. and 3. are met but the emissions unit's stack height or stack gas exit velocity or temperature will be decreased, no construction permit is required for the relocation of the emissions unit if the allowable emissions from the source will not cause or exacerbate the violation of an ambient air quality standard or ambient air increment.(6) Exempt replacements. No construction permit is required for the replacement of a source if all of the following conditions are met: (a) The replacement is for only a portion of a basic emissions unit.(b) Such replacement is not prohibited by any permit, plan approval or special order applicable to the source.(c) The essential components of the basic emissions unit are not replaced through several partial replacements within a 12-month period.(7) Conditions for specific exemptions. To be eligible for a specific exemption under sub. (1) (a) 5., (ce), (cm), (d), (e), (g), (gm), (h), (j), (m), (o), (w), (y) or (z), the owner or operator of a direct stationary source shall keep and maintain records, for a minimum of 5 years, of materials used, emissions, or production rates, that are adequate to demonstrate that the source qualifies for the exemption. Any direct stationary source that ever exceeds any level listed in sub. (1) (a) 5., (ce), (cm), (d), (e), (g), (gm), (h), (j), (m), (o), (w), (y) or (z) is not thereafter eligible for the exemption under that subsection.Wis. Admin.
