Ariz. Admin. Code § R18-2-411 - Permit Requirements for Sources that Locate in Attainment or Unclassifiable Areas and Cause or Contribute to a Violation of Any National Ambient Air Quality Standard

A. Except as provided in subsection (C) or (D), the Director shall deny a permit or permit revision to any major source or major modification that would locate in any attainment or unclassified area, if the source or modification would cause or contribute to a violation of any national ambient air quality standard.

B. A major source or major modification will be considered to cause or contribute to a violation of a national ambient air quality standard when the source or modification would, at a minimum, cause an increase in the concentrations of a regulated NSR pollutant that exceeds the significance level at any locality that does not, or as a result of the increase would not, meet the standard.

C. A proposed major source or major modification subject to subsection (A) may reduce the impact of its emissions upon air quality by obtaining sufficient emission reductions to, at a minimum, compensate for its adverse ambient impact where the major source or major modification would otherwise cause or contribute to a violation of any national ambient air quality standard.

D. Subsection (A) shall not apply to a major stationary source or major modification with respect to a particular pollutant if the owner or operator demonstrates that, as to that pollutant, the source or modification is located in an area designated as nonattainment pursuant to section 107 of the Act.
