This chapter applies to all direct stationary sources which are required under s. 285.60
, Stats., to obtain an operation permit. In accordance with s. 285.60 (6)
, Stats., sources of certain sizes and types are exempt under s. NR 407.03
from the requirement to obtain an operation permit.
This chapter is adopted under ss. 285.11 (1)
, 285.65 (13)
, Stats., to establish a schedule of dates for the submission of operation permit applications and a schedule of dates for requiring operation permits for various categories of direct stationary sources and to specify the content of operation permit applications and operation permits. This chapter also sets forth procedures for revising, suspending and revoking operation permits.

NR 407.02 Definitions.
The definitions contained in chs. NR 400
apply to the terms used in this chapter. In addition, the following definitions apply to the terms used in this chapter:
“Affected state" means either of the following:
Any state that is within 50 miles of the stationary source obtaining an operation permit or undergoing revision or renewal of its operation permit.
Michigan, Illinois, Iowa or Minnesota if that state's air quality may be affected by the stationary source obtaining an operation permit or undergoing revision or renewal of its operation permit.
“Emissions allowable under the permit" means an enforceable permit term or condition required by an applicable requirement that establishes an emission limit, including a work practice standard, or a federally enforceable emissions cap that the source has assumed to avoid an applicable requirement to which the source would otherwise be subject.
“Facility" means all stationary sources emitting air contaminants which belong to the same industrial grouping, are located on one or more contiguous or adjacent properties, and are under the control of the same person, or persons under common control. Emissions resulting from loading, unloading or stockpiling materials to or from vessels or vehicles while at a facility shall be considered as part of the facility's emissions. Air contaminant sources, other than transportation related activities, shall be considered as part of the same industrial grouping if they are classified under the same 2-digit major group as described in the Standard Industrial Classification Manual, 1987, incorporated by reference in s. NR 484.05 (1)
“Fugitive emissions" means those emissions which could not reasonably pass through a stack, chimney, vent, or other functionally equivalent opening.
“Individual operation permit" means an operation permit which is not a general operation permit issued under s. NR 407.10
or a registration operation permit issued under s. NR 407.105
“Major source" means any stationary source, or any group of stationary sources, that is located on one or more contiguous or adjacent properties, is under common control of the same person or persons under common control, belongs to a single major industrial grouping and that is described in par. (a)
. For the purposes of defining “major source", a stationary source or group of stationary sources shall be considered part of a single major industrial grouping if all of the pollutant emitting activities at the source or group of sources have the same 2-digit code as described in the Standard Industrial Classification Manual, 1987, incorporated by reference in s. NR 484.05
A stationary source that, for pollutants other than radionuclides, emits or has the potential to emit, in the aggregate, 10 tons per year (tpy) or more of any single hazardous air pollutant listed under section 112 (b) of the Act (42 USC 7412
(b)), 25 tpy or more of any combination of those hazardous air pollutants, or a lesser quantity as the administrator may establish by rule. Notwithstanding the preceding sentence, emissions from any oil or gas exploration or production well, with its associated equipment, and emissions from any pipeline compressor or pump station may not be aggregated with emissions from other similar units, whether or not the units are in a contiguous area or under common control, to determine whether the units or stations are major sources.
A stationary source that directly emits, or has the potential to emit, 100 tpy or more of any air contaminant subject to regulation under the Act other than particulate matter. For particulate matter, a stationary source is a major source if it emits, or has the potential to emit, 100 tpy of PM10
. The fugitive emissions of a stationary source may not be considered in determining whether it is a major source for the purposes of this definition, unless the source belongs to one of the following categories of stationary sources:
Municipal incinerators capable of charging more than 250 tons of refuse per day.
