A. Any application for a permit or permit revision under this article to construct a new major source or major modification to a major source shall contain an analysis of ambient air quality in the area that the new major source or major modification would affect for each of the following pollutants:
1. For the new source, each pollutant that it would have the potential to emit in a significant amount;
2. For the modification, each pollutant for which it would result in a significant net emissions increase.
B. With respect to any such pollutant for which no Arizona ambient air quality standard exists, the analysis shall contain all air quality monitoring data as the control officer determines is necessary to assess ambient air quality for that pollutant in any area that the emissions of the pollutant would affect.
C. With respect to any such pollutant (other than nonmethane hydrocarbons) for which such a standard does exist, the analysis shall contain continuous air quality monitoring data gathered for purposes of determining whether emissions of that pollutant would cause or contribute to a violation of the standard or any maximum allowable increase.
D. In general, the continuous air quality monitoring data that is required shall have been gathered over a period of at least one year and shall represent at least the year preceding receipt of the application, except that, if the control officer determines that a complete and adequate analysis can be accomplished with monitoring data gathered over a period shorter than one year (but not to be less than four months), the data that is required shall have been gathered over at least that shorter period.
E. The owner or operator of a proposed stationary source or modification to a source of volatile organic compounds who satisfies all conditions of 40 CFR 51, Section IV of Appendix S, may provide post-approval monitoring data for ozone in lieu of providing preconstruction data as required under subsections B, C, and D of this section.
F. Post-Construction Monitoring. The owner or operator of a new major source or major modification shall, after construction of the source or modification, conduct such ambient monitoring as the control officer determines is necessary to determine the effect emissions from the new source or modification may have, or are having, on air quality in any area.
G. Operations of Monitoring Stations. The owner or operator of a new major source or major modification shall meet the requirements of 40 CFR 58, Appendix B, during the operation of monitoring stations for purposes of satisfying subsections B through F of this section.
H. The requirements of subsections B through G of this section shall not apply to a new major source or major modification to an existing source with respect to monitoring for a particular pollutant if:
1. The emissions increase of the pollutant from the new source or the net emissions increase of the pollutant from the modification would cause, in any area, air quality impacts less than the following amounts:
Pollutant | Concentration | Averaging Time |
Pollutant | Concentration | Averaging Time |
Carbon monoxide | 575 ìg/m 3 | 8 hour average |
Nitrogen dioxide | 14 ìg/m 3 | annual average |
PM 10 | 10 ìg/m 3 | 24 hour average |
Sulfur dioxide | 13 ìg/m 3 | 24 hour average |
Lead | 0.1 ìg/m 3 | 24 hour average |
Fluorides | 0.25 ìg/m 3 | 24 hour average |
Total reduced sulfur | 10 ìg/m 3 | 1 hour average |
Hydrogen sulfide | 0.04 ìg/m 3 | 1 hour average |
Reduced sulfur compounds | 10 ìg/m 3 | 1 hour average |
Ozone | increased emissions of less than 100 tons per year of volatile organic compounds or oxides of nitrogen; | |
or,
2. The concentrations of the pollutant in the area that the new source or modification would affect are less than the concentrations listed in subdivision 1 of this subsection.
I. Any application for permit or permit revision under this article to construct a new major source or major modification to a source shall contain:
1. An analysis of the impairment to visibility, soils and vegetation that would occur as a result of the new source or modification and general commercial, residential, industrial and other growth associated with the new source or modification. The applicant need not provide an analysis of the impact on vegetation having no significant commercial or recreational value.
2. An analysis of the air quality impact projected for the area as a result of general commercial, residential, industrial and other growth associated with the new source or modification.
