When required to conduct an air quality analysis under this division:

1. (1) The owner or operator of a source must submit a modeling protocol to DEQ and have it approved before submitting a permit application.

2. (2) In addition to the requirements defined in OAR 340-216-0040 for permit applications, the owner or operator of a source must submit all information necessary to perform any analysis or make any determination required under this division. Such information may include, but is not limited to:

   1. (a) Emissions data for all existing and proposed emission points from the source or modification. This data must represent maximum emissions for the averaging times by regulated pollutant consistent with the ambient air quality standards in OAR chapter 340, division 202.
   2. (b) Stack parameter data, height above ground, exit diameter, exit velocity, and exit temperature, for all existing and proposed emission points from the source or modification;
   3. (c) An analysis of the air quality and visibility impact of the source or modification, including meteorological and topographical data, specific details of models used, and other information necessary to estimate air quality impacts; and
   4. (d) An analysis of the air quality and visibility impacts, and the nature and extent of all commercial, residential, industrial, and other source emission growth, that has occurred since the baseline concentration year in the area the source or modification would significantly affect; and

3. (3) An analysis of the air quality impacts for comparison to significant impact levels, PSD increments, and ambient air quality standards is not required for PM increases equal to or greater than the PM SER. If applicable, DEQ may require the owner or operator of a source to conduct speciation of PM and perform an analysis for PM10 and PM2.5.
