17.16.620   Air quality models.
   A.   Where the control officer requires a person requesting a permit or permit revision under this article to perform air quality impact modeling to obtain such permit or permit revision under this article, the modeling shall be performed in a manner consistent with the "Guideline on Air Quality Models (Revised)".
   B.   Where the person requesting a permit or permit revision under this article can demonstrate that an air quality impact model specified in the "Guideline" is inappropriate, the model may be modified or another model substituted. However, before such modification or substitution can occur the control officer shall make a written finding that:
      1.   No model in the Guideline is appropriate for a particular permit or permit revision under this article under consideration; or
      2.   The data base required for the appropriate model in the Guideline is not available; and
      3.   The model proposed as a substitute or modification is likely to produce results equal or superior to those obtained by models in the Guideline; and
      4.   The model proposed as a substitute or modification has been approved by the administrator.
   C.   Use of a modified or substituted model shall be subject to notice and opportunity for public comment pursuant to Sections 17.12.190 and 17.13.210.
