Ch. NR 447 Note
Chapter NR 447 as it existed on October 31, 1992 was repealed and a new chapter NR 447 was created effective November 1, 1992. Correction made under s. 13.93 (2m) (b) 7., Stats., Register, January, 1997, No. 493
This chapter applies to all air contaminant sources which may emit asbestos, to their owners and operators and to any person whose action causes the emission of asbestos to the ambient air.
This chapter is adopted under ss. 285.11
, Stats., to establish emission limitations for asbestos air contaminant sources, to establish procedures to be followed when working with asbestos materials and to create additional reporting and recordkeeping requirements for owners or operators of asbestos air contaminant sources in order to protect air quality.
NR 447.01 Note
This chapter is based on the federal regulations contained in 40 CFR part 61
, Subpart M.

NR 447.02 Definitions.
The definitions contained in ch. NR 400
apply to the terms used in this chapter. In addition, the following definitions apply to the terms used in this chapter:
“Category I nonfriable ACM" means asbestos-containing packings, gaskets, resilient floor covering and asphalt roofing products containing more than 1% asbestos as determined using the method specified in Appendix E to Subpart E, 40 CFR part 763
, section 1, Polarized Light Microscopy, incorporated by reference in s. NR 484.04 (28)
, that, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.
“Category II nonfriable ACM" means any material, excluding Category I nonfriable ACM, containing more than 1% asbestos as determined using the method specified in Appendix E to Subpart E, 40 CFR part 763
, section 1, Polarized Light Microscopy that, when dry, cannot be crumbled, pulverized or reduced to powder by hand pressure.
“Active waste disposal site" means any disposal site other than an inactive disposal site.
“Adequately wet" means sufficiently mix or penetrate with liquid to prevent the release of particulates. If visible emissions are observed coming from asbestos-containing material, then that material has not been adequately wetted. However, the absence of visible emissions is not sufficient evidence of being adequately wet.
“Asbestos" means the asbestiform varieties of serpentinite (chrysotile), riebeckite (crocidolite), cummingtonite-grunerite (amosite), anthophyllite and actinolite-tremolite.
“Asbestos-containing waste materials" means mill tailings or any waste that contains commercial asbestos and is generated by a source subject to the provisions of this chapter. This term includes filters from control devices, friable asbestos waste material, and bags or other similar packaging contaminated with commercial asbestos. As applied to demolition and renovation operations, this term also includes regulated asbestos-containing material waste and materials contaminated with asbestos including disposable equipment and clothing.
“Asbestos mill" means any facility engaged in converting, or in any intermediate step in converting, asbestos ore into commercial asbestos. Outside storage of asbestos material is not considered a part of the asbestos mill.
“Asbestos tailings" means any solid waste that contains asbestos and is a product of asbestos mining or milling operations.
“Asbestos waste from control devices" means any waste material that contains asbestos and is collected by a pollution control device.
“Commercial asbestos" means any material containing asbestos that is extracted from ore and has value because of its asbestos content.
“Cutting" means to penetrate with a sharp-edged instrument and includes sawing, but does not include shearing, slicing or punching.
“Demolition" means the wrecking or taking out of any load-supporting structural member of a facility together with any related handling operations or the intentional burning of any facility.
“Emergency renovation operation" means a renovation operation that was not planned but results from a sudden, unexpected event that, if not immediately attended to, presents a safety or public health hazard, is necessary to protect equipment from damage, or is necessary to avoid imposing an unreasonable financial burden. This term includes operations necessitated by non-routine failures of equipment.
“Fabricating" means any processing, cutting, sawing or drilling, of a manufactured product that contains commercial asbestos, with the exception of processing at temporary sites (field fabricating) for the construction or restoration of facilities. In the case of friction products, fabricating includes bonding, debonding, grinding, sawing, drilling or other similar operations performed as part of fabricating.
“Facility" means any institutional, commercial, public, industrial or residential structure, installation or building, including any structure, installation or building containing condominiums or individual dwelling units operated as a residential cooperative, but excluding residential buildings having 4 or fewer dwelling units; any ship; and any active or inactive waste disposal site. For purposes of this definition, any building, structure or installation that contains a loft used as a dwelling is not considered a residential structure, installation or building. Any structure, installation or building that was previously subject to this chapter is not excluded, regardless of its current use or function.
“Facility component" means any part of a facility including equipment.
“Friable asbestos material" means any material containing more than 1% asbestos as determined using the method specified in Appendix E to Subpart E, 40 CFR part 763
, section 1, Polarized Light Microscopy, incorporated by reference in s. NR 484.04 (28)
, that, when dry, can be crumbled, pulverized or reduced to powder by hand pressure. If the asbestos content of the friable ACM is less than 10%, as determined by a method other than point counting by polarized light microscopy (PLM), the asbestos content shall be verified by point counting using PLM.
“Fugitive source" means any source of emissions not controlled by an air pollution control device.
“Glove bag" means a sealed compartment with attached inner gloves used for the handling of asbestos-containing materials.
NR 447.02 Note
Properly installed and used, glove bags provide a small work area enclosure typically used for small-scale asbestos stripping operations. Information on glove-bag installation, equipment and supplies, and work practices is contained in OSHA's final rule on occupational exposure to asbestos in 29 CFR 1926.1101
(g)(5)(ii) as in effect on July 1, 2002, incorporated by reference in s. NR 484.03 (4)
“Grinding" means to reduce to powder or small fragments and includes mechanical chipping or drilling.
“In poor condition" means the binding of the material is losing its integrity as indicated by peeling, cracking or crumbling of the material.
“Inactive waste disposal site" means any disposal site or portion of it where additional asbestos-containing waste material has not been deposited within the past year.
“Installation" means any building or structure or any group of buildings or structures at a single demolition or renovation site that are under the control of the same owner or operator, or owner or operator under common control.
“Leak-tight" means designed or constructed so that solids or liquids, including dust, cannot escape or spill out.
“Malfunction" means any sudden and unavoidable failure of air pollution control equipment or process equipment or of a process to operate in a normal or usual manner so that emissions of asbestos are increased.“Malfunction" does not include failures of equipment if they are caused in any way by poor maintenance, careless operation or any other preventable upset conditions, equipment breakdown or process failure.
“Manufacturing" means the combining of commercial asbestos, or, in the case of woven friction products, the combining of textiles containing commercial asbestos, with any other material, including commercial asbestos, and the processing of this combination into a product. Chlorine production is considered a part of manufacturing.
“Natural barrier" means a natural object that effectively precludes or deters access. Natural barriers include physical obstacles such as cliffs, lakes or other large bodies of water, deep and wide ravines, and mountains. Remoteness by itself is not a natural barrier.
