NR 405.18(7)(c)(c) A specification that if the owner or operator applies to renew a PAL in accordance with sub. (10) before the end of the PAL effective period, the PAL does not expire at the end of the PAL effective period, but shall remain in effect until a revised PAL permit is issued by the department.

NR 405.18(7)(d)(d) A requirement that emission calculations for compliance purposes include emissions from startups, shutdowns and malfunctions.

NR 405.18(7)(e)(e) A requirement that, once the PAL expires, the major stationary source is subject to the requirements of sub. (9).

NR 405.18(7)(f)(f) The calculation procedures that the owner or operator shall use to convert the monitoring system data to monthly emissions and annual emissions based on a 12-month rolling total for each month as required by sub. (13) (a).

NR 405.18(7)(g)(g) A requirement that the owner or operator monitor all emissions units in accordance with the provisions under sub. (12).

NR 405.18(7)(h)(h) A requirement to retain the records required under sub. (13) on site. Records may be retained in an electronic format.

NR 405.18(8)(b)1.1. During the PAL effective period, the department shall reopen and revise the PAL permit to do any of the following:

NR 405.18(8)(b)1.a.a. Correct typographical errors in the PAL permit or correct calculation errors made in setting the PAL or reflect a more accurate determination of emissions used to establish the PAL.

NR 405.18(8)(b)1.b.b. Reduce the PAL if the owner or operator of the major stationary source creates creditable emissions reductions for use as offsets under ch. NR 408.

NR 405.18(8)(b)2.2. The department may reopen and revise the PAL permit to do any of the following:

NR 405.18(8)(b)2.a.a. Reduce the PAL to reflect newly applicable federal requirements with compliance dates after the PAL effective date.

NR 405.18(8)(b)2.b.b. Reduce the PAL consistent with any other requirement that is enforceable as a practical matter, and that the department may impose on the major stationary source.

NR 405.18(8)(b)2.c.c. Reduce the PAL if the department determines that a reduction is necessary to avoid causing or contributing to a violation of an NAAQS or a PSD increment violation, or to an adverse impact on an AQRV that has been identified for a federal class I area by a federal land manager and for which information is available to the general public.

NR 405.18(8)(b)3.3. Except for the permit reopening in subd. 1. a. for the correction of typographical or calculation errors that do not increase the PAL level, all reopenings shall be carried out in accordance with the public participation requirements of sub. (5).

NR 405.18(9)(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.
