NR 405.14 NR 405.14 Sources impacting federal Class I areas — additional requirements.

NR 405.14(1) (1) Notice to epa. The department shall transmit to the administrator a copy of each permit application relating to a major stationary source or major modification and provide notice to the administrator of every action related to the consideration of such permit.

NR 405.14(2) (2) Federal land manager. The federal land manager and the federal official charged with direct responsibility for management of Class I lands have an affirmative responsibility to protect the air quality related values (including visibility) of any such lands and to consider, in consultation with the administrator, whether a proposed source or modification would have an adverse impact on such values.

NR 405.14(3) (3) Denial — impact on air quality related values. The department shall allow the federal land manager of any Class I lands the opportunity to present to the department after the department’s preliminary determination required under procedures developed in accordance with s. NR 405.16, a demonstration that the emissions from the proposed major source or major modification would have an adverse impact on the air quality related values (including visibility) of any federal mandatory Class I lands, notwithstanding that the change in air quality resulting from emissions from such source or modification would not cause or contribute to concentrations which would exceed the maximum allowable increases for a Class I area. If the department concurs with such demonstration, the permit may not be issued.

NR 405.14(4) (4) Class I variances. The owner or operator of a proposed major source or major modification may demonstrate to the federal land manager that the emissions from the source would have no adverse impact on the air quality-related values, including visibility, of these lands, notwithstanding that the change in air quality resulting from emissions from the source or modification would cause or contribute to concentrations which would exceed the maximum allowable increases for a Class I area. If the federal land manager concurs with this demonstration and so certifies to the department, the department may, provided that applicable requirements of this chapter are otherwise met, issue the permit with such emission limitations as may be necessary to assure that emissions of particulate matter measured as PM10, sulfur dioxide and nitrogen dioxide would not exceed the following maximum allowable increases over minor source baseline concentration for these air contaminants.

NR 405.14(5) (5) Sulfur dioxide variance by department with federal land manager’s concurrence.

NR 405.14(5)(a) (a) The owner or operator of a proposed major source or major modification which cannot be approved under procedures developed pursuant to sub. (4) may demonstrate to the department that the source or modification cannot be constructed by reason of any maximum allowable increase for sulfur dioxide for periods of 24-hours or less applicable to any Class I area and, in the case of federal mandatory Class I areas, that a variance under this subsection would not adversely affect the air quality related values of the area (including visibility).

NR 405.14(5)(b) (b) The department, after consideration of the federal land manager’s recommendation (if any) and subject to his or her concurrence, may grant, after notice and an opportunity for a public hearing, a variance from such maximum allowable increase.

NR 405.14(5)(c) (c) If such variance is granted, the department shall issue a permit to such major source or major modification in accordance with provisions developed pursuant to sub. (7), provided that the applicable requirements of this chapter are otherwise met.

NR 405.14(6) (6) Variance by the department with the concurrence of the president of the United States.

NR 405.14(6)(a) (a) The recommendations of the department and the federal land manager shall be transferred to the president in any case where the department recommends a variance in which the federal land manager does not concur.

NR 405.14(6)(b) (b) The president may approve the department’s recommendation if he or she finds that such variance is in the national interest.

NR 405.14(6)(c) (c) If such a variance is approved, the department shall issue a permit in accordance with provisions developed pursuant to the requirements of sub. (7), provided that the applicable requirements of this chapter are otherwise met.

NR 405.14(7) (7) Emission limitations for presidential denial or departmental variance. In the case of a permit issued under procedures developed pursuant to sub. (5) or (6), the major source or major modification shall comply with emission limitations as may be necessary to assure that emissions of sulfur dioxide from the major source or major modification would not, during any day on which the otherwise applicable maximum allowable increases are exceeded, cause or contribute to concentrations which would exceed the following maximum allowable increases over the baseline concentration and to assure that such emissions would not cause or contribute to concentrations which exceed the otherwise applicable maximum allowable increase for periods of exposure of 24 hours or less for more than 18 days, not necessarily consecutive, during any annual period.

NR 405.18(1) (1) Applicability.

NR 405.18(1)(a) (a) This section applies to any existing major stationary source which wishes to operate under a PAL. The department may approve the use of a PAL for any existing major stationary source if the source and its application for a PAL meets all of the requirements in this section.

NR 405.18(1)(b) (b) Any physical change in or change in the method of operation of a major stationary source that maintains its total source-wide emissions below the PAL level, meets the requirements in this section and complies with the PAL permit:

NR 405.18(1)(b)1. 1. Is not a major modification for the PAL regulated air contaminant.

NR 405.18(1)(b)2. 2. Does not have to be approved under this chapter.

NR 405.18(1)(b)3. 3. Is not subject to the provisions in s. NR 405.16 (2).

NR 405.18(1)(c) (c) Except as provided under par. (b) 3., a major stationary source shall continue to comply with all applicable federal or state requirements, emission limitations and work practice requirements that were established prior to the effective date of the PAL.

NR 405.18(2) (2) Definitions. The following definitions apply to terms used in this subsection for the purpose of developing and implementing PALs consistent with this section.

NR 405.18(2)(a) (a) “Allowable emissions” has the meaning given in s. NR 405.02 (2), except as this definition is modified according to both of the following:

NR 405.18(2)(a)1. 1. The allowable emissions for any emissions unit shall be calculated considering any emission limitations that are enforceable as a practical matter on the emissions unit’s potential to emit.

NR 405.18(2)(a)2. 2. An emissions unit’s potential to emit shall be determined using the definition in s. NR 405.02 (25), except that the words “or enforceable as a practical matter” should be added after “federally enforceable”.

NR 405.18(2)(b) (b) “Major emissions unit” means either of the following:

NR 405.18(2)(b)1. 1. Any emissions unit that emits or has the potential to emit 100 tons per year or more of the PAL regulated air contaminant in an attainment area.

NR 405.18(2)(b)2. 2. Any emissions unit that emits or has the potential to emit the PAL regulated air contaminant in an amount that is equal to or greater than the major source threshold for the PAL regulated air contaminant as defined by the Act for nonattainment areas.

NR 405.18 Note Note: In accordance with the definition of major stationary source in section 182 (c) of the Act, an emissions unit would be a major emissions unit for VOC if the emissions unit is located in a serious ozone nonattainment area and it emits or has the potential to emit 50 or more tons of VOC per year.
