1 No de minimis air quality level is provided for ozone. However, any net emissions increase of one hundred (100) tons per year or more of VOCs or nitrogen oxides subject to PSD would be required to perform an ambient impact analysis including the gathering of ambient air quality data.
The owner or operator of the proposed source or modification shall demonstrate that allowable emission increases from the proposed source or modification, in conjunction with all other applicable emissions increases or reductions (including secondary emissions), would not cause or contribute to air pollution in violation of:
The owner or operator of a proposed source or modification shall submit all information necessary to perform any analysis or make any determination required under this Section .
