NR 406.04(6) (6) Exempt replacements. No construction permit is required for the replacement of a source if all of the following conditions are met:

NR 406.04(6)(a) (a) The replacement is for only a portion of a basic emissions unit.

NR 406.04(6)(b) (b) Such replacement is not prohibited by any permit, plan approval or special order applicable to the source.

NR 406.04(6)(c) (c) The essential components of the basic emissions unit are not replaced through several partial replacements within a 12-month period.

NR 406.04(7) (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.

NR 406.07 NR 406.07 Scope of permit exemption.

NR 406.07(1) (1) Exemption or the granting of an exemption under this chapter from the requirement to obtain a permit does not relieve any person from compliance with the emission limitations of chs. NR 400 to 499, the air quality requirements of ch. NR 404, the reporting requirements of ch. NR 438, or with any other provision of law.

NR 406.07(2) (2) If a source undergoes a modification which is exempt from the requirement to obtain a construction permit under s. NR 406.04 (4), it will not be treated as a modified source for purposes of the emission limitations under chs. NR 400 to 499.

NR 406.07(3) (3) A source that undergoes a modification which is exempt from the requirement to obtain a construction permit under s. NR 406.04 (1f) or (1k) shall be treated as a new or modified source for the purposes of the emission limitations under chs. NR 400 to 499 unless the modification is excluded from being considered a modification under s. NR 406.04 (4).

NR 406.07 History History: Renum. from NR 406.04 (7) (a) and (b), Register, April, 1988, No. 388, eff. 5-1-88; am. (2), Register, September, 1988, No. 393, eff. 10-1-88; emerg. am.

NR 406.075(1) (1) Except as provided in sub. (2), all terms and conditions in a construction permit, including any provisions designed to limit a stationary source’s potential to emit, are federally enforceable by the administrator under section 113 of the Act (42 USC 7413).

NR 406.075(2) (2) Notwithstanding sub. (1), the department shall specifically designate as not federally enforceable any terms and conditions included in the permit that are not required under the Act, under any of the federal regulations implementing the Act or under the state implementation plan.

NR 406.075 History History: CR 04-106: cr. Register November 2005 No. 599, eff. 12-1-05.

NR 406.08 NR 406.08 Action on permit applications.

NR 406.08(1) (1) This section applies to actions on permits for which applications are received on or after August 1, 2015. This section does not apply to actions on applications for permits where the source commences construction, reconstruction, replacement, relocation, or modification prior to issuance of a construction permit. This section does not apply to construction permits which are subject to the notice, comment, and hearing provisions of s. 293.43, 295.45, or 295.57, Stats.

NR 406.08(2) (2) 

NR 406.08(2)(a) (a) The department shall make a determination under s. 285.61 (8), Stats., on a permit application within 205 business days of receipt of a complete application for construction or modification of a major stationary source as defined in s. NR 405.02 (22) or a major source as defined in s. NR 408.02 (21), unless compliance with s. 1.11, Stats., requires a longer time. For a major source that is located in an attainment area, the department shall complete its responsibilities under s. 1.11, Stats., within one year.

NR 406.08(2)(b) (b) The department shall make a determination under s. 285.61 (8), Stats., on a permit application within 145 business days of receipt of a complete application for construction or modification of any stationary source not described in par. (a), unless compliance with s. 1.11, Stats., requires a longer time.

NR 406.08(3) (3) If the department does not make a determination within the applicable time period specified in sub. (2), the department may not impose an application fee for the permit under s. NR 410.03, and shall refund any application fee submitted with the application.

NR 406.08(4) (4) 

NR 406.08(4)(a) (a) The Forest County Potawatomi Community shall have the opportunity to review best available control technology (BACT) or maximum achievable control technology (MACT) determinations made by the department for any new or modified source that is either of the following:

NR 406.08(4)(a)1. 1. Wholly or partially locating or located within a radius of 22.25 miles from the geographic center of the FCPC Class I area, as identified in s. NR 400.02 (66m).

NR 406.08(4)(a)2. 2. Wholly or partially locating or located within 62 miles of the FCPC Class I area, and has a modeled impact exceeding 1 microgram per cubic meter averaged over any 24-hour period for mercury or for any regulated pollutant that has an ambient air quality standard in s. NR 404.04.

NR 406.08(4)(b) (b) Disagreements between the department and the Forest County Potawatomi Community regarding BACT or MACT determinations are subject to dispute resolution but the department shall act on a permit application according to time period requirements under ss. 285.61 and 285.62, Stats.

NR 406.08 Note Note: The geographic center of the FCPC Class I area, as identified in s. NR 400.02 (66m), was determined by finding the center of a rectangle placed around the outer most portions of the Class I area. The 22.25-mile radius was determined by adding 10 miles to the distance of the outermost portion of the FCPC Class I area from the geographic center of the FCPC Class I area.

NR 406.08 Note The Department has determined that any source wholly located outside of a circle with a radius of 74.25 miles from the geographic center of the FCPC Class I area is not within 62 miles of the FCPC Class I area. The 74.25-mile radius was determined by adding 62 miles to the distance of the outermost portion of the FCPC Class I area from the geographic center of the FCPC Class I area. It is the Department’s intent that this circle be used as a screening tool for determining applicability of this subsection, and evidence that a source is wholly outside of this circle will be accepted as proof that the source is not within 62 miles of the FCPC Class I area.

NR 406.08 Note The relationship between the State of Wisconsin and the Forest County Potawatomi Community with regard to the FCPC Class I area is established in a 1999 Class I Final Agreement. Dispute resolution follows a process agreed to by the Department and the Forest County Potawatomi Community pursuant to the Final Agreement.
