(22) The following apply to the definition of the term "insignificant emissions unit":

(a) "insignificant emissions unit" means any activity or emissions unit located within a source that:

(i) has a potential to emit less than five tons per year of any regulated pollutant;

(ii) has a potential to emit less than 500 pounds per year of lead;

(iii) has a potential to emit less than 500 pounds per year of hazardous air pollutants listed pursuant to section 112(b) of the FCAA; and

(iv) is not regulated by an applicable requirement, other than a generally applicable requirement that applies to all emission units subject to this subchapter.

(b) Fugitive sources associated with an emissions unit are to be quantified with that emissions unit and are not considered insignificant emission units.

(23) "Major source" means any stationary source (or any group of stationary sources that are located on one or more contiguous or adjacent properties, and are under common control of the same person (or persons under common control)) belonging to a single major industrial grouping and that are described in (23)(a) through (c). For the purposes of defining "major source," a stationary source or group of stationary sources shall be considered part of a single industrial grouping if all of the pollutant emitting activities at such source or group of sources on contiguous or adjacent properties belong to the same major group (i.e., all have the same two-digit code) as described in the Standard Industrial Classification Manual, 1987.

(a) A major source under section 112 of the FCAA, which is defined as:

(i) for pollutants other than radionuclides, any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit, in the aggregate, ten tons per year or more of any hazardous air pollutant which has been listed pursuant to section 112(b) of the FCAA, 25 tons per year or more of any combination of such hazardous air pollutants, or such lesser quantity as the board 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 are not aggregated with emissions from other similar units, whether or not such units are in a contiguous area or under common control, to determine whether such units or stations are major sources; or

(ii) for radionuclides, "major source" shall have the meaning specified by the department by rule.

(b) A major stationary source of air pollutants that directly emits or has the potential to emit, 100 tons per year or more of any air pollutant. The fugitive emissions of a stationary source shall not be considered in determining whether it is a major stationary source, unless the source belongs to one of the following categories of stationary source:

(i) coal cleaning plants (with thermal dryers) ;

(ii) kraft pulp mills;

(iii) Portland cement plants;

(iv) primary zinc smelters;
