NR 460 to 469 if it were a major source, subsequently increases its emissions of hazardous air pollutants, or its potential to emit hazardous air pollutants, such that the source is a major source, the source shall be subject to the relevant emission standard or other requirement. NR 460.05(2)(2) Compliance dates for new and reconstructed sources. NR 460.05(2)(a)(a) Except as specified in pars. (c) and (d), the owner or operator of a new or reconstructed affected source for which construction or reconstruction commences after proposal of a relevant standard that has an initial startup before the effective date of a relevant standard established under 40 CFR part 63 pursuant to section 112 (d), (f) or (h) of the Act (42 USC 7412 (d), (f) or (h)) shall comply with the standard not later than the standard’s effective date. NR 460.05(2)(b)(b) Except as specified in pars. (c) and (d), the owner or operator of a new or reconstructed source that has an initial startup after the effective date of a relevant standard established under 40 CFR part 63 pursuant to section 112 (d), (f) or (h) of the act (42 USC 7412 (d), (f) or (h)) shall comply with the standard upon startup of the source. NR 460.05(2)(c)(c) The owner or operator of an affected source for which construction or reconstruction is commenced after the proposal date of a relevant standard established under 40 CFR part 63 pursuant to section 112 (d), (f) or (h) of the act (42 USC 7412 (d), (f) or (h)) but before federal promulgation of the standard shall comply with the relevant emission standard not later than the date 3 years after the federal promulgation date if: NR 460.05(2)(c)1.1. The promulgated standard, that is, the relevant standard, is more stringent than the proposed standard; for purposes of this subdivision, a finding that controls or compliance methods are “more stringent” shall include control technologies or performance criteria and compliance or compliance assurance methods that are different but are substantially equivalent to those required by the promulgated rule, as determined by the administrator or his or her authorized representative. NR 460.05(2)(c)2.2. The owner or operator complies with the standard as proposed during the 3-year period immediately after the effective date. NR 460.05(2)(d)(d) The owner or operator of an affected source for which construction or reconstruction is commenced after the proposal date of a relevant standard established pursuant to section 112 (d) of the Act (42 USC 7412 (d)) but before the proposal date of a relevant standard established pursuant to section 112 (f) (42 USC 7412 (f)) may not be required to comply with the section 112 (f) emission standard until the date 10 years after the date construction or reconstruction is commenced, except that, if the section 112 (f) standard is promulgated more than 10 years after construction or reconstruction is commenced, the owner or operator shall comply with the standard as provided in pars. (a) and (b). NR 460.05(2)(e)(e) The owner or operator of a new MACT source that is subject to the compliance requirements of par. (c) or (d) shall notify the department in accordance with s. NR 460.08 (4). NR 460.05(2)(f)(f) When an area source becomes a major source by the addition of equipment or operations that meet the definition of new affected source in the relevant standard, the portion of the existing facility that is a new affected source shall comply with all requirements of that standard applicable to new MACT sources. The source owner or operator shall comply with the relevant standard upon startup. NR 460.05(3)(a)(a) After the effective date of a relevant standard established under 40 CFR part 63 pursuant to section 112 (d) or (h) of the act (42 USC 7412 (d) or (h)), the owner or operator of an existing source shall comply with the standard by the compliance date established in the applicable subparts of 40 CFR part 63. NR 460.05 NoteNote: Except as otherwise provided for in section 112 of the act (42 USC 7412), the compliance date established for an existing source in an applicable subpart of 40 CFR part 63 will not exceed 3 years after the effective date of the standard. NR 460.05(3)(b)(b) If an existing source is subject to a standard established under 40 CFR part 63 pursuant to section 112 (f) of the Act (42 USC 7412 (f)), the owner or operator shall comply with the standard by the date 90 days after the standard’s effective date, or by the date specified in an extension granted to the source by the department under sub. (7) (c) 2., whichever is later. NR 460.05(3)(c)(c) Except as provided in sub. (2) (f), the owner or operator of an area source that increases its emissions of, or its potential to emit, hazardous air pollutants such that the source becomes a major source shall be subject to relevant standards for existing sources. These sources shall comply by the date specified in the standards for existing area sources that become major sources. If no compliance date is specified in the standard, the source shall have a period of time to comply with the relevant emission standard that is equivalent to the compliance period specified in the relevant standard for sources in existence at the time the standard becomes effective. NR 460.05(3m)(3m) Determination of whether a relocated source is reconstructed or existing. As indicated in s. NR 460.02 (10), the removal of all equipment comprising an affected source from an existing location and reinstallation of the equipment at a new location does not constitute construction. The owner or operator of an existing affected source that is relocated may elect not to reinstall minor ancillary equipment including, but not limited to, piping, ductwork and valves. However, removal and reinstallation of an affected source will be construed as reconstruction if it satisfies the criteria for reconstruction as defined in s. NR 460.02 (32). The costs of replacing minor ancillary equipment shall be considered in determining whether the existing affected source is reconstructed. NR 460.05(4)(a)1.1. At all times, including periods of startup, shutdown and malfunction, the owner or operator shall operate and maintain any affected source, including associated air pollution control and monitoring equipment, in a manner consistent with safety and good air pollution control practices for minimizing emissions. During a period of startup, shutdown or malfunction, the general duty to minimize emissions requires that the owner or operator reduce emissions from the affected source to the greatest extent which is consistent with safety and good air pollution control practices. The general duty to minimize emissions during a period of startup, shutdown or malfunction does not require the owner or operator to achieve emission levels that would be required by the applicable standard at other times if this is not consistent with safety and good air pollution control practices, nor does it require the owner or operator to make any further efforts to reduce emissions if levels required by the applicable standard have been achieved. Determination of whether the operation and maintenance procedures are being used will be based on information available to the department, which may include monitoring results; review of operation and maintenance procedures, including the startup, shutdown and malfunction plan required in par. (c); review of operation and maintenance records; and inspections of the source. NR 460.05(4)(a)2.2. Malfunctions shall be corrected as soon as practicable after their occurrence. To the extent that an unexpected event arises during a startup, shutdown or malfunction, an owner or operator shall comply by minimizing emissions during any startup, shutdown and malfunction event consistent with safety and good air pollution control practices. NR 460.05(4)(a)3.3. Operation and maintenance requirements established pursuant to section 112 of the act (42 USC 7412) are enforceable independent of emissions limitations or other requirements in relevant standards. NR 460.05(4)(c)1.1. The owner or operator of an affected source shall develop a written startup, shutdown and malfunction plan that meets the requirements of s. NR 439.11 and describes, in detail, procedures for operating and maintaining the source during periods of startup, shutdown and malfunction and a program of corrective action for malfunctioning process, air pollution control and monitoring equipment used to comply with the relevant standard. The startup, shutdown and malfunction plan does not need to address any scenario that would not cause the source to exceed an applicable emission limitation in the relevant standard. This plan shall be developed by the owner or operator by the source’s compliance date for that relevant standard. The plan shall be designed to achieve all of the following: NR 460.05(4)(c)1.a.a. Ensure that, at all times, the owner or operator operates and maintains each affected source, including associated air pollution control and monitoring equipment, in a manner which satisfies the general duty to minimize emissions established by par. (a) 1. NR 460.05(4)(c)1.b.b. Ensure that owners or operators are prepared to correct malfunctions as soon as practicable after their occurrence in order to minimize excess emissions of hazardous air pollutants. NR 460.05(4)(c)1.c.c. Reduce the reporting burden associated with periods of startup, shutdown and malfunction, including corrective action taken to restore malfunctioning process and air pollution control equipment to its normal or usual manner of operation. NR 460.05(4)(c)3.3. When actions taken by the owner or operator during a startup or shutdown, and the startup or shutdown causes the source to exceed any applicable emission limitation in the relevant emission standards, or during a malfunction, including actions taken to correct a malfunction, are consistent with the procedures specified in the affected source’s startup, shutdown and malfunction plan, the owner or operator shall keep records for that event which demonstrate that the procedures specified in the plan were followed. These records may take the form of a checklist, or other effective form of recordkeeping that confirms conformance with the startup, shutdown and malfunction plan and describes the actions taken for that event. In addition, the owner or operator shall keep records of these events as specified in s. NR 460.09 (2), including records of the occurrence and duration of each startup or shutdown, if the startup or shutdown causes the source to exceed any applicable emission limitation in the relevant emission standards, and of the occurrence and duration of each malfunction of operation and each malfunction of the air pollution control and monitoring equipment. Furthermore, the owner or operator shall confirm that actions taken during the relevant reporting period during periods of startup, shutdown and malfunction were consistent with the affected source’s startup, shutdown and malfunction plan in the semiannual, or more frequent, startup, shutdown and malfunction report required in s. NR 460.09 (4) (e).
