South Dakota Administrative Rules › Title 74 - Department of Environment And Natural Resources › Article 74:36 - Air pollution control program › Chapter 74:36:01 - Definitions › Section 74:36:01:08 - Major source defined

Current through Register Vol. 51, page 10, July 15, 2024
A major source is any source or any group of sources that is located on
	 one or more contiguous or adjacent properties, that is under control of the
	 same person or of persons under common control, that belongs to a single major
	 industrial grouping, and that is any of the following:
(1) A major source under § 112 of the
  Clean Air Act defined as a source or group of sources located within a
  contiguous area and under common control that emits or has the potential to
  emit, considering controls, in the aggregate, 10 tons per year (tpy) or more of
  any hazardous air pollutant which has been listed pursuant to § 112(b) of
  the Clean Air Act, 25 tpy or more of any combination of such hazardous air
  pollutants, or a lesser quantity established by rule by the administrator of
  the EPA. Emissions from any oil exploration or production well and 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
  such units are in a contiguous area or under common control, to determine
  whether such units or stations are major sources; or
(2) A major source of air pollutants, as
  defined in § 302 of the Clean Air Act, that directly emits or has the
  potential to emit 100 tpy or more of any air pollutant subject to regulation as
  required by EPA, including any major source of fugitive emissions of any such
  pollutant, as determined by rule by the administrator of the EPA; or
(3) A major source as defined in Part D of
  Title I of the Clean Air Act, including;
(a)
  For ozone nonattainment areas, sources with the potential to emit 100 tons or
  more per year of volatile organic compounds or oxides of nitrogen in areas
  classified as "marginal" or "moderate, "50 tons or more per year in areas
  classified as "serious," 25 tons or more per year in areas classified as
  "severe," and 10 tons or more per year in areas classified as "extreme." The
  references in this subdivision to 100, 50, 25, and 10 tons per year of nitrogen
  oxides do not apply to any source for which the administrator of the EPA has
  made a finding, under § 182(f)(1) or (2) of the Clean Air Act, that the
  requirements of § 182(f) of the Clean Air Act do not apply;
(b) For ozone transport regions established
  pursuant to § 184 of the Clean Air Act, sources with the potential to emit
  50 tons or more per year of volatile organic compounds;
(c) For carbon monoxide nonattainment areas
  that are classified as "serious" and in which sources contribute significantly
  to carbon monoxide levels as determined under rules issued by the administrator
  of the EPA, sources with the potential to emit 50 tons or more per year of
  carbon monoxide; and
(d) For
  particulate matter (PM10) nonattainment areas classified as "serious," sources
  with the potential to emit 70 tons or more per year of PM10.
A source or group of sources is considered as part of a single
	 industrial grouping if all of the pollutant-emitting activities of the source
	 or group of sources belong to the same major group (i.e. which have the same
	 two-digit code) as described in the Standard Industrial Classification Manual,
	 1987.
