Nev. Admin. Code § 445B.094 - "Major source" defined

1. Except as otherwise provided in subsection 3, "major source" means any stationary source that:
(a) Is located on one or more contiguous or adjacent properties;
(b) Is under the common control of the same person or persons;
(c) Belongs to a single major industrial grouping as described in the Standard Industrial Classification Manual, as incorporated by reference in NAC 445B.221; and
(d) Meets one of the following conditions:
(1) Is located in a nonattainment area and is required to obtain an operating permit pursuant to 42 U.S.C. §§ 7501 to 7515, inclusive;
(2) Directly emits or has the potential to emit:
(I) One hundred tons per year or more of any regulated air pollutant, excluding particulate matter more than 10 microns in diameter; or
(II) Ten tons per year or more of a hazardous air pollutant or 25 tons per year or more of any combination of hazardous air pollutants or a lesser quantity as established by the Commission; or
(3) Is located in a particulate matter (PM10) "serious" nonattainment area and directly emits or has the potential to emit 70 tons per year or more of PM10.

The Director shall consider fugitive emissions in determining whether a stationary source is major for any source category listed in 40 C.F.R. § 52.21(b)(1)(iii), as adopted by reference pursuant to NAC 445B.221, or whether a stationary source of a hazardous air pollutant is a major source. To determine whether a stationary source is a major source of hazardous air pollutants under 42 U.S.C. § 7412, emissions from any oil or gas exploration or production well, with its associated equipment, and emissions from any pipeline compressor or pump station must not be aggregated with emissions from other similar units, whether or not such units are in a contiguous area or under common control.

2. In determining whether a stationary source is a major source, the Director shall not consider the emissions from mobile sources subject to regulation under Title II of the federal Clean Air Act, 42 U.S.C. §§ 7521 to 7590, inclusive, or from nonroad engines.
3. For the purposes of the program for the prevention of significant deterioration of air quality (PSD), the term "major source" is synonymous with the term "major stationary source" as that term is defined in 40 C.F.R. § 52.21(b)(1), as adopted by reference in NAC 445B.221.
