Chapter NR 406

NR 406.17(2)(a)1. 1. Actual emissions of each air contaminant from the construction, reconstruction, replacement, relocation or modification of the stationary source or sources will not exceed 25% of any major source threshold in s. NR 407.02 (4), over any 12 consecutive month period, except that emissions of lead may not exceed 0.5 tons over any 12 consecutive month period.

NR 406.17(2)(a)2. 2. The facility is not, and will not as a result of the project be, a major source under ch. NR 405, 407 or 408.

NR 406.17(2)(b) (b) Notwithstanding par. (a), the department may issue registration construction permits for coverage of other types of stationary sources that the department determines have or will have low actual or potential emissions, in response to a petition submitted under s. NR 406.18.

NR 406.17(3) (3) Sources ineligible for coverage under a registration construction permit. Notwithstanding the existence of a registration construction permit, an individual stationary source may not be covered under a registration construction permit if any of the following criteria apply:

NR 406.17(3)(a) (a) The emissions unit or units are an affected source under ch. NR 409, a municipal solid waste combustion source under s. NR 500.03 (151) or an infectious waste combustion source.

NR 406.17(3)(b) (b) The proposed project would result in one or more new or existing emissions units at the facility being required to obtain a permit under ch. NR 405 or 408.

NR 406.17 Note Note: An example is the addition of an emissions unit at a PSD or nonattainment area major source that is considered a major modification to that source. Another example is a project that results in an emissions unit either upstream or downstream from the project increasing its emissions such that it would be required to obtain a permit under ch. NR 405 or 408.

NR 406.17(3)(c) (c) The emissions unit or units 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 406.11 (1) (g).

NR 406.17(3)(d) (d) The construction, reconstruction, replacement, relocation, or modification of the emissions unit or units 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 construction permit, or that are determined by the department to not preclude eligibility for the registration construction permit.

NR 406.17(4) (4) Procedure for determining coverage under a registration construction permit for an individual source.

NR 406.17(4)(a) (a) An owner or operator of a stationary source who applies for coverage under a registration construction permit shall submit an application using department approved registration permit application forms.

NR 406.17 Note Note: 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 the department approved registration permit application forms.

NR 406.17(4)(b) (b) An owner or operator of a stationary source 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 construction permit, shall apply for a different type of permit.

NR 406.17(4)(c) (c) Within 15 days after the receipt of the application form prescribed by the department, the department shall provide one of the following to an applicant for a registration construction permit:

NR 406.17(4)(c)1. 1. Written notice of the department’s determination that the source is covered under the registration construction permit.

NR 406.17(4)(c)2. 2. A written description of any information that is missing from the application for coverage under the registration construction permit.

NR 406.17(4)(c)3. 3. Written notice of the department’s determination that the source does not qualify for coverage under the registration construction permit, specifically describing the reasons for that determination.

NR 406.17(4)(d) (d) The department shall grant coverage under the registration construction permit if the owner or operator of the source applies for coverage and meets the eligibility requirements in the registration construction permit, unless the source is ineligible under sub. (3).

NR 406.17(4)(e) (e) For the purpose of determining whether a source is eligible for coverage under a registration construction permit, the source’s emissions shall be calculated using the terms and conditions listed in the registration construction permit.

NR 406.17 Note Note: 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 406.17(5) (5) Incorporation of registration construction permit into the facility operation permit.

NR 406.17(5)(a) (a) When submitting an application for coverage under a registration construction permit, the owner or operator of the source shall also submit an application for an operation permit or a request to revise its operation permit pursuant to ch. NR 407. Prior to issuing or revising the operation permit, the department shall determine that the applicable permit approval criteria under ss. 285.63 and 285.64, Stats., have been met.

NR 406.17(5)(b) (b) The registration construction permit requirements, emission caps and limitations shall be established as conditions in the operation permit.

NR 406.17(6) (6) Application for a different permit.

NR 406.17(6)(a) (a) An owner or operator of a stationary source that is covered under a registration construction permit may submit a request to the department to withdraw coverage under the registration construction permit and allow the source to be covered under a general construction permit or be issued an individual construction permit. The owner or operator shall submit a written request for withdrawal of coverage under the registration construction permit and a complete application for a general or individual construction permit.

NR 406.17(6)(b) (b) An owner or operator of a stationary source that has an individual construction permit may submit a request to the department to revise or revoke the individual construction permit pursuant to s. NR 406.11 (3) and allow the source to be covered under a registration construction permit. The owner or operator shall submit to the department a written request for revision or revocation of the individual construction permit and a complete application for a registration construction permit under this section.

NR 406.17(6)(c) (c) An owner or operator of a stationary source that is covered under a general construction permit may submit a request to the department to withdraw the source from coverage under the general construction permit and allow the source to be covered under a registration construction permit. The owner or operator shall submit to the department a written request for withdrawal of the general construction permit and a complete application for a registration construction permit under this section.

NR 406.17(6)(d) (d) The owner or operator shall submit a request for revision or revocation of a construction permit or withdrawal from coverage under a construction permit under this subsection on department approved forms.

NR 406.17 Note Note: 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 406.17(6)(e) (e) The owner or operator of a facility submitting an application for a different permit under this subsection shall comply with the existing permit until the department has issued or granted coverage under the different permit.

NR 406.18 NR 406.18 Petition for issuance of general construction permits and registration construction permits.

NR 406.18(1) (1) A person may petition the department to make a determination that a category of stationary source meets the criteria for a general construction permit under s. 285.60 (3), Stats., and s. NR 406.16 (1). A person may petition the department to make a determination that a stationary source meets the criteria for a registration construction permit under s. 285.60 (2g), Stats., and s. NR 406.17 (1) and (2) (b). The department may consider the number of sources that would be eligible for the permit, the complexity of air regulations applicable to the sources, the likelihood that sources would need source-specific emission limitations and other relevant factors in determining its priority for developing a general or registration construction permit. Within 30 days after receipt of the petition, the department shall provide a written response to the petitioner granting or denying the petition. If the department grants the petition, the department shall issue the general construction permit or the registration construction permit as soon as practicable, but no later than 365 days after receipt of the petition.

NR 406.18(2) (2) The person shall submit the petition on department approved forms.
