			  APPLICABILITY.
(a) The affected facility to
			  which this section applies is each steam generating unit that commences
			  construction, modification, or reconstruction after June 19, 1984, and that has
			  a heat input capacity from fuels combusted in the steam generating unit of more
			  than 29 MW (100 million Btu/hour).
(b) Any affected facility meeting the
			  applicability requirements under par. (a) and commencing construction,
			  modification, or reconstruction after June 19, 1984, but on or before June 19,
			  1986, is subject to the following standards:
1. Coal-fired affected facilities having a
			  heat input capacity between 29 and 73 MW (100 and 250 million Btu/hour),
			  inclusive, are subject to the particulate matter and nitrogen oxides standards
			  under this section.
2. Coal-fired
			  affected facilities having a heat input capacity greater than 73 MW (250
			  million Btu/hour) and meeting the applicability requirements under s.
			  NR
			  440.19 (standards of performance for fossil fuel-fired
			  steam generators) are subject to the particulate matter and nitrogen oxides
			  standards under this section and to the sulfur dioxide standards in s.
			  NR
			  440.19(4).
3. Oil-fired affected facilities having a
			  heat input capacity between 29 and 73 MW (100 and 250 million Btu/hour),
			  inclusive, are subject to the nitrogen oxides standards in this
			  section.
4. Oil-fired affected
			  facilities having a heat input capacity greater than 73 MW (250 million
			  Btu/hour) and meeting the applicability requirements in s.
			  NR
			  440.19 (standards of performance for fossil fuel-fired
			  steam generators) are also subject to the nitrogen oxides standards in this
			  section and the particulate matter and sulfur dioxide standards in s.
			  NR
			  440.19(3) and (4).
(c) Affected facilities which also
			  meet the applicability requirements under s.
			  NR 440.26
			  (standards of performance for petroleum refineries) are subject to the
			  particulate matter and nitrogen oxides standards under this section and the
			  sulfur dioxide standards under s.
			  NR
			  440.26(5).
(d) Affected facilities which also meet the
			  applicability requirements in s.
			  NR
			  440.21 (standards of performance for incinerators) are
			  subject to the nitrogen oxides and particulate matter standards in this
			  section.
(e) Steam generating units
			  meeting the applicability requirements in s.
			  NR
			  440.20 (standards of performance for electric utility
			  steam generating units) are not subject to this section.
(f) Any change to an existing steam
			  generating unit for the sole purpose of combusting gases containing TRS as
			  defined in s.
			  NR
			  440.45(2) is not considered a
			  modification under s.
			  NR
			  440.14 and the steam generating unit is not subject to
			  this section.
(g) Affected
			  facilities which meet the applicability requirements under s.
			  NR
			  440.216(1) are not subject to this
			  section.
(h) Unless and until s.
			  NR 440.50
			  is revised to extend the applicability of s.
			  NR 440.50
			  to steam generator units subject to this section, this section will continue to
			  apply to combined cycle gas turbines that are capable of combusting more than
			  29 MW (100 million Btu/hour) heat input of fossil fuel in the steam generator.
			  Only emissions resulting from combustion of fuels in the steam generating unit
			  are subject to this section. (The gas turbine emissions are subject to s.
			  NR
			  440.50.)
