    (a) Definitions. For purposes of this section, the following 
definitions apply:
    (1) Administrator means the Administrator of the United States 
Environmental Protection Agency or the Administrator's duly authorized

capacity greater than 25 MWe and produced electricity for sale under a 
firm contract to the electric grid.
    (ii) For units that commenced operation on or after January 1, 1997 
and before January 1, 1999, a unit serving at any time during 1997 or

    (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 
that did not serve during 1995 or 1996 a generator producing electricity

output capacity of the unit.
    (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findings for sources in a specific State would be withdrawn.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. 
Paragraph (k) of this section indefinitely stays the effectiveness of 
the affirmative technical determinations with respect to the 8-hour 
ozone standard.
    (1) The States that submitted such petitions are Connecticut, Maine, 
Massachusetts, New Hampshire, New York, Pennsylvania, Rhode Island, and 
Vermont (each of which, hereinafter in this section, may be referred to 
also as a ``petitioning State'').
    (2) The new and existing sources of NOX emissions covered 
by the petitions that emit or would emit NOX emissions in 
amounts that make such significant contributions are large electric 
generating units (EGUs) and large non-EGUs.
