NR 460.01(1)(a)(a) This chapter applies to the owner or operator of any facility affected by a standard promulgated by EPA under section 112 of the act (
42 USC 7412), except as otherwise specified in the appendices of this chapter and as provided in
pars. (b) and
(d).
NR 460.01 Note
Note: The general provisions of this chapter eliminate the repetition of requirements applicable to all owners or operators affected by the national emission standards for hazardous air pollutants promulgated under
40 CFR part 63, which are commonly called MACT standards. These standards will regulate specific categories of stationary sources that emit, or have the potential to emit, one or more hazardous air pollutants listed pursuant to section 112 (b) of the Act (
42 USC 7412 (b)). The department plans to group the source categories it regulates under chs.
NR 460 to
469.
NR 460.01 NoteSome delay may occur between the promulgation of the federal standard in
40 CFR part 63 and subsequent promulgation of the standard in chs.
NR 460 to
469. Permits under ch.
NR 406 or
407 may, under s.
285.65, Stats., specify applicable requirements from
40 CFR part 63 and refer to applicable requirements in this chapter before the specific requirements for the source category can be promulgated in chs.
NR 460 to
469.
NR 460.01 Note
To obtain the most current list of categories of sources to be regulated under section 112 of the Act (
42 USC 7412), or to obtain the most recent regulation promulgation schedule established pursuant to section 112 (e) of the Act (
42 USC 7412 (e)), contact the department's Bureau of Air Management, PO Box 7921, Madison WI 53707, telephone number (608) 266-7718, or EPA's Emissions Standards Division (MD-13), U.S. EPA, Office of Air Quality Planning and Standards, Research Triangle Park NC 27711, telephone number (919) 541-2380.
NR 460.01(1)(b)
(b) Special provisions in a relevant standard established under
40 CFR part 63 after March 16, 1994 shall supersede any conflicting provisions of this chapter.
NR 460.01 Note
Note: This paragraph addresses federal MACT standards that have not yet been promulgated by the department under chs.
NR 460 to
469. Standards established under
40 CFR part 63 include a table that identifies special provisions which supersede the general provisions of
40 CFR part 63 Subpart A. This table in the federal standard will be used as a guide for identifying special provisions that supersede comparable provisions of this chapter.
NR 460.01(1)(c)
(c) If the owner or operator of an existing source obtains a compliance date extension for the source in accordance with the provisions of
40 CFR part 63, Subpart D, the owner or operator shall comply with all requirements of this chapter except those requirements that are specifically overridden in the extension of the compliance for that source.
NR 460.01 Note
Note: Extensions under the early reduction program of
40 CFR part 63, Subpart D, are only available from EPA.
NR 460.01(1)(d)
(d) This chapter does not apply to the owner or operator of any facility subject to the provisions of
s. NR 468.20.
NR 460.01(1)(e)2.
2. In the case of CFR appendices incorporated by reference in
ch. NR 484, if a more recent date is specified in the applicable section of
ch. NR 484, that date shall apply.
NR 460.01(2)
(2) Purpose. Chapters NR 460 to
469 are adopted to enable the department to implement and enforce standards for stationary sources promulgated by EPA under section 112 of the act (
42 USC 7412), as required by ss.
285.27 (2) and
285.65, Stats. This chapter is adopted under ss.
285.11,
285.13 and
285.17, Stats., to establish general provisions for notification, recordkeeping, monitoring and reporting requirements for sources of hazardous air contaminants.
NR 460.01 Note
Note: This chapter is based on federal regulations contained in
40 CFR part 63 subpart A as last revised on May 16, 2007. The chapter also reflects the federal authority delegation provisions of
40 CFR part 63 subpart E as last revised on September 14, 2000. In addition to meeting the requirements of this chapter, any major new or reconstructed source subject to a relevant standard under
40 CFR part 63 is required to obtain a construction permit under ch.
NR 406 as indicated in s.
NR 406.04 (2) (h). Also, most other new or modified sources are required to submit an operation permit application before commencing operation under s.

Definitions. For terms not defined in this section, the definitions contained in
ch. NR 400 apply to the terms used in this chapter. In addition, the definitions in this section apply to the terms used in this chapter and, for terms not defined in
chs. NR 462 to
464 and
466 to
469 or the subchapters of
chs. NR 463 and
465, to the terms used in those chapters or subchapters as well. If this section defines a term which is also defined in
ch. NR 400, the definition in this section applies in this chapter and in
chs. NR 462 to
464 and
466 to
469 and the subchapters of
chs. NR 463 and
465 rather than the definition in
ch. NR 400, except that when one of those chapters or subchapters has its own definition of the term, that definition applies in that chapter or subchapter.
NR 460.02(1)
(1) “Affected source" means one of the following:
NR 460.02(1)(a)
(a) For each section 112 (d) (
42 USC 7412 (d)) standard for which the initial proposed rule is signed by the administrator on or before June 30, 2002, the stationary source, the group of stationary sources, or the portion of a stationary source that is regulated by a relevant standard or other requirement established pursuant to section 112 of the Act (
42 USC 7412). Each relevant standard in
chs. NR 462 to
469 may further define the “affected source" for the purposes of that standard.
NR 460.02(1)(b)
(b) For each standard published pursuant to section 112 (d) of the Act (
42 USC 7412 (d)) for which the initial proposed rule is signed by the administrator after June 30, 2002, the collection of equipment, activities, or both within a single contiguous area and under common control that is included in a section 112 (c) (
42 USC 7412 (c)) source category or subcategory for which a section 112 (d) (
42 USC 7412 (d)) standard or other relevant standard is established pursuant to section 112 of the Act (
42 USC 7412).
NR 460.02 Note
Note: Each relevant standard will define the affected source as defined in sub. (1) unless the administrator finds that a different definition is warranted based on a published justification as to why this definition would result in significant administrative, practical or implementation problems and why the different definition would resolve those problems. The term affected source, as used in this chapter and chs.
NR 462 to
469, is separate and distinct from any other use of that term in EPA or department regulations such as those implementing title IV of the Act or the Wisconsin acid rain control program. Affected source may be defined differently for
40 CFR part 63 than “affected facility" and “stationary source" in
40 CFR parts 60 and
61, respectively. The procedures for adopting an alternative definition of affected source apply to each section 112 (d) standard (
42 USC 7412 (d)) for which the initial proposed rule is signed by the administrator after June 30, 2002.
NR 460.02(2)
(2) “Alternative emission limitation" means conditions established pursuant to section 112 (i) (5) or (6) of the act (
