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)
NR 460.01 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
NR 460.01 Note
Some 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
. Permits under ch. NR 406
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
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.
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
This paragraph addresses federal MACT standards that have not yet been promulgated by the department under chs. NR 460
. 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.
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
Extensions under the early reduction program of 40 CFR part 63
, Subpart D, are only available from EPA.
This chapter does not apply to the owner or operator of any facility subject to the provisions of s. NR 468.20
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.
(2) Purpose. Chapters NR 460
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)
, Stats. This chapter is adopted under ss. 285.11
, Stats., to establish general provisions for notification, recordkeeping, monitoring and reporting requirements for sources of hazardous air contaminants.
NR 460.01 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) (i)
. Also, most other new or modified sources are required to submit an operation permit application before commencing operation under s. NR 407.04 (1) (b) 3.

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
or the subchapters of chs. NR 463
, 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
and the subchapters of chs. NR 463
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.
"Affected source" means one of the following:
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
may further define the "affected source" for the purposes of that standard.
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
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
, 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
, 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.
"Alternative emission limitation" means conditions established pursuant to section 112 (i) (5) or (6) of the act (42 USC 7412
(i) (5) or (6)) by the department.
"Alternative emission standard" means an alternative, at least equivalent means of emission limitation as determined by the administrator.
NR 460.02 Note
The procedure under which approval of an alternative emission standard may be requested is given in 40 CFR 63.6
"Alternative test method" means any method of sampling and analyzing for an air pollutant that has been demonstrated to the department's satisfaction, using Method 301 in Appendix A of 40 CFR part 63
, incorporated by reference in s. NR 484.04 (25)
, to produce results adequate for the department's determination of compliance when used in place of a test method specified in chs. NR 460
"Area source" means any stationary source of hazardous air pollutants that is not a major source as defined in this chapter or chs. NR 462
"Capture device" means a hood, enclosed room, floor sweep or other means of collecting solvent emissions or other pollutants into a duct so that the pollutant can be directed to a pollution control device such as an incinerator or carbon adsorber.
"Commenced" means, with respect to construction or reconstruction of an affected source, that an owner or operator has undertaken a continuous program of construction or reconstruction or that an owner or operator has entered into a contractual obligation to undertake and complete, within a reasonable time, a continuous program of construction or reconstruction.
"Compliance date" means the date by which an affected source is required to be in compliance with a relevant standard, limitation, prohibition, or any federally enforceable requirement established by the department under chs. NR 406
pursuant to section 112 of the act (42 USC 7412
"Compliance schedule" means any of the following:
In the case of an affected source that is in compliance with all applicable requirements established under 40 CFR part 63
, a statement that the source will continue to comply with the requirements.
In the case of an affected source that is required to comply with applicable requirements by a future date, a statement that the source will meet the requirements on a timely basis and, if required by an applicable requirement, a detailed schedule of the dates by which each step toward compliance will be reached.
In the case of an affected source not in compliance with all applicable requirements established under 40 CFR part 63
, a schedule of remedial measures, including an enforceable sequence of actions or operations with milestones and a schedule for the submission of certified progress reports, where applicable, leading to compliance with a relevant standard, limitation, prohibition or any federally enforceable requirement established pursuant to section 112 of the act (42 USC 7412
) for which the affected source is not in compliance. This compliance schedule shall resemble and be at least as stringent as that contained in any judicial consent decree or administrative order to which the source is subject. Any schedule of compliance shall be supplemental to, and may not sanction noncompliance with, the applicable requirements on which it is based.
"Construction" means the on-site fabrication, erection or installation of an affected source. Construction does not include the removal of all equipment comprising an affected source from an existing location and reinstallation of the equipment at a new location.
NR 460.02 Note
Section NR 460.05 (3m)
addresses source relocation.
"Continuous emission monitoring system" or "CEMS" means the total equipment that may be required to meet the data acquisition and availability requirements of 40 CFR part 63
, used to sample, condition, if applicable, analyze and provide a record of emissions.
"Continuous monitoring system" or "CMS" means a continuous emission monitoring system, continuous opacity monitoring system, continuous parameter monitoring system, or other manual or automatic monitoring that is used for demonstrating compliance with an applicable regulation on a continuous basis.
"Continuous opacity monitoring system" or "COMS" means a continuous monitoring system that measures the opacity of emissions.
"Continuous parameter monitoring system" means the total equipment that may be required to meet the data acquisition and availability requirements of 40 CFR part 63
, used to sample, condition, if applicable, analyze and provide a record of process or control system parameters.
"Control system" means the combination of capture and control devices used to reduce emission of air contaminants.
"Effective date" means either of the following:
With regard to an emission standard established under 40 CFR part 63
, the date of promulgation in the federal register of the standard.
With regard to an alternative emission limitation or equivalent emission limitation determined by the administrator or the department, the date that the alternative emission limitation or equivalent emission limitation becomes effective according to the provisions of 40 CFR part 63
or chs. NR 460
