Ozone and PM10-10 precursors

(a) Ozone. The requirements of Part 9 of OAC 252:100-8 applicable to major stationary sources and major modifications of VOCs shall apply to NOX emissions from major stationary sources and major modifications of NOX in an ozone transport region (as defined in 42 U.S.C.§ 7511c) or in any ozone nonattainment area, except in ozone nonattainment areas or in portions of an ozone transport region where the Administrator has granted a NOX waiver applying the standards set forth under section 182(f) of the Act and the waiver continues to apply. (b) PM10-10 precursors. The requirements of Part 9 of OAC 252:100-8 applicable to major stationary sources and major modifications of PM10-10 shall also apply to major stationary sources and major modifications of PM10-10 precursors, except where the Administrator determines that such sources do not contribute significantly to PM10-10 levels that exceed the PM10-10 national ambient air quality standards in the area.
