(4) General requirements for establishing PALs. NR 405.18(4)(a)(a) The department may establish a PAL in a permit for a major stationary source if all of the following requirements are met:
NR 405.18(4)(a)1.
1. The PAL imposes an annual emission limitation in tons per year, that is enforceable as a practical matter, for the entire major stationary source. For each month during the PAL effective period after the first 12 months of establishing a PAL, the major stationary source owner or operator shall show that the sum of the monthly emissions from each emissions unit under the PAL for the previous 12 consecutive months is less than the PAL. For each month during the first 11 months from the PAL effective date, the major stationary source owner or operator shall show that the sum of the preceding monthly emissions from the PAL effective date for each emissions unit under the PAL is less than the PAL.
NR 405.18(4)(a)2.
2. The PAL is established in a PAL permit that meets the public participation requirements in
sub. (5).
NR 405.18(4)(a)4.
4. The PAL includes fugitive emissions, to the extent quantifiable, from all emissions units that emit or have the potential to emit the PAL regulated air contaminant at the major stationary source.
NR 405.18(4)(a)7.
7. The owner or operator of the major stationary source with a PAL complies with the monitoring, recordkeeping and reporting requirements provided in
subs. (12) to
(14) for each emissions unit under the PAL through the PAL effective period.
NR 405.18(4)(b)
(b) At no time during or after the PAL effective period are emissions reductions of a PAL regulated air contaminant that occur during the PAL effective period creditable as decreases for purposes of offsets under
ch. NR 408 unless the PAL is reduced by the amount of the emissions reductions and the reductions would be creditable in the absence of the PAL.
NR 405.18(5)
(5) Public participation requirements for PALs. PALs shall be established, renewed or increased, through a procedure that is consistent with
s. NR 405.15. This includes the requirement that the department provide the public with notice of the proposed approval of a PAL permit and at least a 30-day period for submittal of public comment. The department shall address all material comments before taking final action on the permit.

par. (b) shall be subtracted from the PAL level.
NR 405.18(6)(e)
(e) For newly constructed units, which do not include modifications to existing units, on which actual construction began after the 24-month period, in lieu of adding the baseline actual emissions established under
par. (b), the emissions shall be added to the PAL level in an amount equal to the potential to emit of the units.
NR 405.18(6)(f)
(f) The department shall specify a reduced PAL level in the PAL permit to become effective on the future compliance date of any applicable federal or state regulatory requirements that the department is aware of prior to issuance of the PAL permit.
NR 405.18 Note
Note: If the source owner or operator will be required to reduce emissions from industrial boilers in half from baseline emissions of 60 ppm NO
X to a new rule limit of 30 ppm, the permit shall contain a future effective PAL level that is equal to the current PAL level reduced by half of the original baseline emissions of the unit.

(9) Expiration of a PAL. Any PAL that is not renewed in accordance with the procedures in
sub. (10) shall expire at the end of the PAL effective period, and the following requirements shall apply:
NR 405.18(9)(a)
(a) For each emissions unit, or each group of emissions units, that existed under the PAL, the owner or operator shall comply with an allowable emission limitation under a revised permit established according to the following procedures:
NR 405.18(9)(a)1.
1. Within the time frame specified for PAL renewals in
sub. (10) (b), the major stationary source shall submit a proposed allowable emission limitation for each emissions unit, or each group of emissions units, if a grouping is more appropriate as determined by the department, by distributing the PAL allowable emissions for the major stationary source among each of the emissions units that existed under the PAL. If the PAL had not yet been adjusted for an applicable requirement that became effective during the PAL effective period, as required under
sub. (10) (e), the distribution shall be made as if the PAL had been adjusted.
NR 405.18(9)(a)2.
2. Based upon the information submitted under
subd. 1., the department shall determine whether and how the PAL allowable emissions will be distributed and issue a revised permit under
s. NR 406.035 incorporating allowable limits for each emissions unit, or each group of emissions units, as the department determines is appropriate.
NR 405.18(9)(b)
(b) The owner or operator of each emissions unit or group of emissions units shall comply with the allowable emission limitation on a 12-month rolling basis. The department may approve the use of monitoring systems, such as source testing, or emission factors, other than CEMS, CERMS, PEMS or CPMS, to demonstrate compliance with the allowable emission limitation.
NR 405.18(9)(c)
(c) Until the department issues the revised permit incorporating allowable limits for each emissions unit, or each group of emissions units, as required under
par. (a) 2., the owner or operator shall continue to comply with a source-wide, multi-unit emissions cap equivalent to the level of the PAL emission limitation.
NR 405.18(9)(d)
(d) Any physical change or change in the method of operation at the major stationary source shall be subject to the requirements of this chapter if the change constitutes a major modification.
NR 405.18(9)(e)
(e) The owner or operator shall continue to comply with any state or federal applicable requirements, such as BACT, RACT or NSPS, that may have applied either during the PAL effective period or prior to the PAL effective period except for those emission limitations that had been established pursuant to
s. NR 405.16 (2), but were eliminated by the PAL in accordance with the provisions in
sub. (1) (b) 3.
NR 405.18(10)(a)(a) The department shall follow the procedures specified in
sub. (5) in approving any request to renew a PAL and shall provide both the proposed PAL level and a written rationale for the proposed PAL level to the public for review and comment. During the public review, any person may propose a PAL level for the source for consideration by the department.
NR 405.18(10)(b)
(b) The owner or operator shall submit a timely application to the department to request renewal of a PAL. A timely application is one that is submitted at least 6 months prior to, but not earlier than 18 months from, the date of expiration of the PAL. If the owner or operator submits a complete application to renew the PAL within this time period, the PAL shall continue to be effective until the revised permit with the renewed PAL is issued.
NR 405.18(10)(c)
(c) The application to renew a PAL permit shall contain all of the following information:
NR 405.18(10)(c)3.
3. The sum of the potential to emit of all emissions units under the PAL, with supporting documentation.
NR 405.18(10)(c)4.
4. Any other information the owner or operator wishes the department to consider in determining the appropriate level for renewing the PAL.
NR 405.18(10)(d)
(d) In determining whether and how to adjust the PAL, the department shall consider the options outlined in
subds. 1. and
2. However, in no case may any adjustment fail to comply with
subd. 3. The adjustment options, and requirements, are as follows:
NR 405.18(10)(d)1.
1. If the emissions level calculated in accordance with
sub. (6) is equal to or greater than 80% of the existing PAL level, the department may renew the PAL at the same level without considering the factors set forth in
subd. 2.
NR 405.18(10)(d)2.
2. The department may set the PAL at a level that it determines to be more representative of the source's baseline actual emissions, or that it determines to be appropriate considering air quality needs, advances in control technology, anticipated economic growth in the area, desire to reward or encourage the source's voluntary emissions reductions, or other factors as specifically identified by the department in a written rationale.
NR 405.18(10)(d)3.
3. Notwithstanding
subds. 1. and
2., if the potential to emit of the major stationary source is less than the PAL, the department shall adjust the PAL to a level no greater than the potential to emit of the source. The department may not approve a renewed PAL level higher than the current PAL, unless the major stationary source has complied with the provisions of
sub. (11).
NR 405.18(10)(e)
(e) If the compliance date for a state or federal requirement that applies to the PAL source occurs during the PAL effective period, and if the department has not already adjusted for the requirement, the PAL shall be adjusted at the time of PAL renewal or operation permit renewal, whichever occurs first.
NR 405.18(11)
(11) Increasing a PAL during the PAL effective period. NR 405.18(11)(a)(a) The department may increase a PAL level only if the owner or operator complies with all of the following provisions:
NR 405.18(11)(a)1.
1. The owner or operator shall submit a complete application to request an increase in the PAL level for a PAL major modification. The application shall identify the emissions units contributing to the increase in emissions so as to cause the major stationary source's emissions to equal or exceed its PAL.
NR 405.18(11)(a)2.
2. As part of this application, the owner or operator shall demonstrate that the sum of the baseline actual emissions of the small emissions units, plus the sum of the baseline actual emissions of the significant and major emissions units under the PAL assuming application of BACT-equivalent controls, plus the sum of the allowable emissions of the new or modified emissions units, exceeds the PAL. The level of control that would result from BACT-equivalent controls on each significant or major emissions unit shall be determined by conducting a new BACT analysis at the time the application is submitted, unless the emissions unit is currently required to comply with a BACT or LAER requirement that was established within the preceding 10 years. The assumed control level for that emissions unit shall be equal to the level of BACT or LAER that currently applies to that emissions unit.
NR 405.18(11)(a)3.
3. The owner or operator obtains a major NSR permit for all emissions units identified in
subd. 1., regardless of the magnitude of the emissions increase from them. These emissions units shall comply with any emissions control requirements resulting from the major NSR process, for example, BACT, even though they have also become subject to the PAL or continue to be subject to the PAL.
NR 405.18(11)(b)
(b) The PAL permit shall require that the increased PAL level shall be effective on the day any emissions unit that is part of the PAL major modification becomes operational and begins to emit the PAL regulated air contaminant.
NR 405.18(11)(c)
(c) The department shall calculate the new PAL as the sum of the allowable emissions for each modified or new emissions unit, plus the sum of the baseline actual emissions of the significant and major emissions units, assuming application of BACT-equivalent controls as determined in accordance with
par. (a) 2., plus the sum of the baseline actual emissions of the small emissions units.
NR 405.18(11)(d)
(d) The PAL permit shall be revised to reflect the increased PAL level pursuant to the public notice requirements of
sub. (5).
NR 405.18(12)(a)1.1. Each PAL permit shall contain enforceable requirements for the monitoring system that accurately determines plantwide emissions of the PAL regulated air contaminant in terms of mass per unit of time. Any monitoring system authorized for use in the PAL permit shall be based on sound science and meet generally acceptable scientific procedures for data quality and manipulation. Additionally, the information generated by any authorized system shall meet minimum legal requirements for admissibility in a judicial proceeding to enforce the PAL permit.
NR 405.18(12)(a)2.
2. Except as provided for in
subd. 3., the PAL monitoring system shall employ one or more of the 4 general monitoring approaches meeting the minimum requirements in
par. (b) and shall be approved by the department.
NR 405.18(12)(a)3.
3. Notwithstanding
subd. 2., the owner or operator may employ an alternative monitoring approach that meets
subd. 1. if approved by the department.
NR 405.18(12)(a)4.
4. Failure to use a monitoring system that meets the requirements of this subsection renders the PAL invalid.
NR 405.18(12)(b)
(b) The following are acceptable general monitoring approaches when conducted in accordance with the minimum requirements in
pars. (c) to
(i):
NR 405.18(12)(b)1.
1. Mass balance calculations for activities using coatings or solvents.
NR 405.18(12)(c)
(c) An owner or operator using mass balance calculations to monitor PAL regulated air contaminant emissions from activities using coating or solvents shall do all of the following:
NR 405.18(12)(c)1.
1. Provide a demonstrated means of validating the published content of the PAL regulated air contaminant that is contained in or created by all materials used in or at the emissions unit.
NR 405.18(12)(c)2.
2. Assume that the emissions unit emits all of the PAL regulated air contaminant that is contained in or created by any raw material or fuel used in or at the emissions unit, if it cannot otherwise be accounted for in the process.
NR 405.18(12)(c)3.
3. Where the vendor of a material or fuel, which is used in or at the emissions unit, publishes a range of pollutant content from the material, use the highest value of the range to calculate the PAL regulated air contaminant emissions unless the department determines there is site-specific data or a site-specific monitoring program to support another content within the range.
NR 405.18(12)(d)
(d) An owner or operator using CEMS to monitor PAL regulated air contaminant emissions shall ensure that the CEMS does both of the following:
