(i) For units that commenced operation before January 1, 1997, a
unit that has a maximum design heat input greater than 250 mmBtu/hr and

(4) New sources means new and modified sources.
(5) NOX means oxides of nitrogen.
(6) OTAG means the Ozone Transport Assessment Group (active 1995-

(b) Purpose and applicability. Paragraphs (c), (e)(1) and (e)(2),
(g), and (h)(1) and (h)(2) of this section set forth the Administrator's
findings with respect to the 1-hour national ambient air quality
standard (NAAQS) for ozone that certain new and existing sources of
emissions of nitrogen oxides (``NOX'') in certain States emit
or would emit NOX in violation of the prohibition in section
110(a)(2)(D)(i) of the Clean Air Act (CAA) on emissions in amounts that
contribute significantly to nonattainment in certain States that
submitted petitions in 1997-1998 addressing such NOX
emissions under section 126 of the CAA. Paragraphs (d), (e)(3) and
(e)(4), (f), and (h)(3) and (h)(4) of this section set forth the
Administrator's affirmative technical determinations with respect to the
8-hour NAAQS for ozone that certain new and existing sources of
emissions of NOX in certain States emit or would emit
NOX in violation of the prohibition in section
110(a)(2)(D)(i) of the CAA on emissions in amounts that contribute
significantly to nonattainment in, or interfere with maintenance by,
certain States that submitted petitions in 1997-1998 addressing such
NOX emissions under section 126 of the CAA. (As used in this
section, the term new source includes modified sources, as well.)
Paragraph (i) of this section explains the circumstances under which the
findings for sources in a specific State would be withdrawn. Paragraph
(j) of this section sets forth the control requirements that apply to
the sources of NOX emissions affected by the findings.
