104 STAT. 2424 PUBLIC LAW 101-549—NOV. 15, 1990 "(2) Notwithstanding table 1, in the case of a severe area with a 1988 ozone design value between 0.190 and 0.280 ppm, the attainment date shall be 17 years (in lieu of 15 years) after the date of the enactment of the Clean Air Amendments of 1990. "(3) At the time of publication of the notice under section 107(d)(4) (relating to area designations) for each ozone nonattainment area, the Administrator shall publish a notice announcing the classification of such ozone nonattainment area. The provisions of section 172(a)(1)(B) (relating to lack of notice and comment and judicial review) shall apply to such classification. "(4) If an area classified under paragraph (1) (Table 1) would have been classified in another category if the design value in the area were 5 percent greater or 5 percent less than the level on which such classification was based, the Administrator may, in the Administrator's discretion, within 90 days after the initial classification, by the procedure required under paragraph (3), adjust the classification to place the area in such other category. In making such adjustment, the Administrator may consider the number of exceedances of the national primary ambient air quality standard for ozone in the area, the level of pollution transport between the area and other affected areas, including both intrastate and interstate transport, and the mix of sources and air pollutants in the area. "(5) Upon application by any State, the Administrator may extend for 1 additional year (hereinafter referred to as the 'Extension Year') the date specified in table 1 of paragraph (1) of this subsection if— "(A) the State has complied with all requirements and commitments pertaining to the area in the applicable implementation plan, and "(B) no more than 1 exceedance of the national ambient air quality standard level for ozone has occurred in the area in the year preceding the Extension Year. No more than 2 one-year extensions may be issued under this paragraph for a single nonattainment area. " (b) NEW DESIGNATIONS AND RECLASSIFICATIONS. — "(1) NEW DESIGNATIONS TO NONATTAINMENT. — Any area that is designated attainment or unclassifiable for ozone under section 107(d)(4), and that is subsequently redesignated to nonattainment for ozone under section 107(d)(3), shall, at the time of the redesignation, be classified by operation of law in accordance with table 1 under subsection (a). Upon its classification, the area shall be subject to the same requirements under section 110, subpart 1 of this part, and this subpart that would have applied had the area been so classified at the time of the notice under subsection (a)(3), except that any absolute, fixed date applicable in connection with any such requirement is extended by operation of law by a period equal to the length of time between the date of the enactment of the Clean Air Act Amendments of 1990 and the date the area is classified under this paragraph. "(2) RECLASSIFICATION UPON FAILURE TO ATTAIN.— (A) Within 6 months following the applicable attainment date (including any extension thereof) for an ozone nonattainment area, the Administrator shall determine, based on the area's design value (as of the attainment date), whether the area attained the standard by that date. Except for any Severe or Extreme area.
