NR 407.105(2)(a)(a) A registration operation permit shall be issued for facilities that meet all of the criteria: NR 407.105(2)(a)1.1. The calendar year sum of actual emissions of each air contaminant from the facility may not exceed 25% of any major source threshold in s. NR 407.02 (4), except that for lead, emissions may not exceed 0.5 tons per calendar year. NR 407.105(2)(a)2.2. The stack-vented emissions are exhausted from unobstructed discharge points that are within 10 degrees of vertical. This criterion does not apply to stacks serving any of the emission units listed in s. NR 407.05 (4) (c) 9. For the purposes of this paragraph, horizontal discharge vents that only discharge general building ventilation are not considered stacks. NR 407.105 NoteNote: Valves designed to open and close at the point of discharge are considered to be unobstructed if they are open at the time of emission.
NR 407.105(2)(a)3.3. The stack is taller than any building that influences the dispersion of emissions from the stack. A building is considered to influence the dispersion of emissions from any stack that exists within a circle around the building, the radius of which is 5 times the height of the building. This criterion does not apply to stacks serving any of the emission units listed in s. NR 407.05 (4) (c) 9. For the purposes of this paragraph, horizontal discharge vents that only discharge general building ventilation are not considered stacks. NR 407.105(2)(a)4.4. An owner or operator of a facility whose stacks do not meet the criteria in subds. 2. and 3. may demonstrate through air dispersion modeling that the facility’s emissions do not and will not cause or exacerbate a violation of any ambient air quality standard or ambient air increment. If an air dispersion model is not available for one or more pollutants, the demonstration for that pollutant shall rely on the department’s air quality analysis conducted under sub. (1) (b). NR 407.105(2)(b)(b) Notwithstanding par. (a), the department may issue registration operation permits for coverage of other types of facilities that the department determines have or will have low actual or potential emissions, in response to a petition submitted under s. NR 407.107. NR 407.105(3)(3) Sources ineligible for coverage under a registration operation permit. Notwithstanding the existence of a registration operation permit, an individual facility may not be covered under a registration operation permit if any of the following criteria apply: NR 407.105(3)(b)(b) One or more emissions units at the facility would be subject to an emission limitation or emission standard under section 111 of the Act (42 USC 7411) or under section 112 of the Act (42 USC 7412), other than those contained in the registration operation permit or determined by the department to not preclude eligibility for the registration operation permit. NR 407.105(3)(c)(c) The facility’s emissions cause or exacerbate, or may cause or exacerbate, a violation of any ambient air quality standard or ambient air increment, as determined by the department through an air quality assessment conducted in accordance with s. NR 407.15 (8). NR 407.105(4)(4) Procedure for determining coverage under a registration operation permit for an individual facility. NR 407.105(4)(a)(a) An owner or operator of a facility who applies for coverage under a registration operation permit shall submit an application using department approved forms. NR 407.105 NoteNote: Contact the regional offices or service centers of the department or the Permits and Stationary Source Modeling Section of the Bureau of Air Management, 608-266-7718, for information on how to obtain and submit the department approved registration permit application forms.
NR 407.105(4)(b)(b) An owner or operator of a facility who requests or requires emission limits, terms or conditions that require case-by-case review and approval by the department, or emission limits, terms or conditions other than, or in addition to, those contained in the registration operation permit, shall apply for a different type of permit. NR 407.105(4)(c)(c) Within 15 days after the receipt of an application for coverage, the department shall provide one of the following to an applicant for a registration operation permit: NR 407.105(4)(c)1.1. Written notice of the department’s determination that the facility is covered under a registration operation permit. NR 407.105(4)(c)2.2. A written description of any information that is missing from the application for coverage under a registration operation permit. NR 407.105(4)(c)3.3. Written notice of the department’s determination that the facility does not qualify for coverage under a registration operation permit, specifically describing the reasons for that determination. NR 407.105(4)(d)(d) The department shall grant coverage under the registration operation permit if the owner or operator of the facility applies for coverage and meets the eligibility requirements in the registration operation permit, unless the facility is ineligible for coverage under sub. (3). NR 407.105(4)(e)(e) For the purpose of determining whether a source is eligible for coverage under a registration operation permit, the source’s emissions shall be calculated using the terms and conditions listed in the registration operation permit. NR 407.105 NoteNote: The permit terms and conditions may include capture and control efficiencies. The Air Emissions Management System (AEMS) requires the owner or operator of a source to calculate actual annual emissions for reporting to the inventory using the terms and conditions in a permit.
NR 407.105(5)(5) Construction or modification under a registration operation permit. NR 407.105(5)(a)(a) No construction permit is required prior to commencing construction, reconstruction, replacement, relocation or modification of a stationary source if the facility is covered under a registration operation permit and the construction, reconstruction, replacement, relocation or modification will not result in the facility violating any term or condition of the registration operation permit. NR 407.105(5)(b)(b) If a construction permit is required, the owner or operator shall obtain a construction permit under ch. NR 405, 406, or 408, as applicable. The owner or operator may not commence construction prior to receiving the construction permit. The owner or operator shall also apply for an individual operation permit, a revision of its individual operation permit or a general operation permit under this chapter. NR 407.105 NoteNote: The construction permit may be an individual, general or registration construction permit.
NR 407.105(6)(a)(a) An owner or operator of a facility that is covered under a registration operation permit may submit a request to the department to withdraw the source from coverage under the registration operation permit and allow the facility to be covered under a general operation permit or be issued an individual operation permit. The owner or operator shall submit a written request for the withdrawal of the registration operation permit and a complete application for an individual or general operation permit under s. NR 407.05 or 407.10. NR 407.105(6)(b)(b) An owner or operator of a facility that has an individual operation permit may submit a request to the department to revoke the individual operation permit pursuant to s. NR 407.15 and allow the facility to be covered under a registration operation permit. A complete application for a registration operation permit submitted under this section shall be considered a request for revocation of the existing individual operation permit. NR 407.105(6)(c)(c) An owner or operator of a facility that is covered under a general operation permit may submit a request to the department to withdraw coverage under the general operation permit and allow the facility to be covered under a registration operation permit. A complete application for a registration operation permit submitted under this section shall be considered a request for withdrawal of coverage under the general permit. NR 407.105(6)(d)(d) The owner or operator shall submit a request for revocation or withdrawal of an operation permit under this subsection on department approved forms. NR 407.105 NoteNote: Contact the regional offices or service centers of the department or the Permits and Stationary Source Modeling Section of the Bureau of Air Management, 608-266-7718, for information on how to obtain and submit the department approved forms.

NR 407.105(7)(7) Additional provisions related to registration operation permits. NR 407.105(7)(a)(a) An owner or operator of a facility operating in compliance with a registration operation permit shall be deemed to be in compliance with the applicable requirements in chs. NR 400 to 499 if the owner or operator conducts a reasonable search and evaluation to identify applicable requirements and to determine whether the facility is meeting the applicable requirements, is operating in compliance with these applicable requirements and complies with par. (b). A reasonable search and evaluation includes a search and evaluation of chs. NR 400 to 499, and shall include a reasonable effort to review other readily accessible information relevant to the facility’s operations, such as data bases, workshops and materials available through trade associations, vendors, the department’s small business clean air assistance program, the U.S. environmental protection agency and other recognized sources of information on air regulations. The owner or operator shall document, in writing, the results of the search and evaluation and shall keep the documents at the facility for inspection upon request for as long as the facility is covered under the registration operation permit. NR 407.105(7)(b)(b) The owner or operator will not be deemed to be out of compliance with the applicable requirements in chs. NR 400 to 499 if an applicable requirement that was previously not identified through the search and evaluation described in par. (a) is later identified, if the owner or operator does all of the following: NR 407.105(7)(b)1.1. Submits written notification to the department within 21 days of identifying the applicable requirement. NR 407.105(7)(b)2.2.
