A. For Class I sources, a significant revision shall be used for an application requesting a permit revision that does not qualify as a minor permit revision or as an administrative amendment. A significant revision that is only required because of a change described in Section 17.12.110(A)(6) or (7) shall not be considered a significant permit revision under Part 70 for the purposes of 40 CFR 64.5(a)(2). Every significant change in existing monitoring permit terms or conditions and every relaxation of reporting or record keeping permit terms or conditions shall follow significant revision procedures.
B. Any modifications to major sources of federally listed hazardous air pollutants, and any reconstruction of a source, or a process or production unit, under Section 112(g) of the Act and regulations promulgated thereunder, shall follow significant revision procedures and any rules adopted under A.R.S. §§ 49-426.03 and 49-480.03.
C. Significant permit revisions shall meet all requirements of this chapter for applications, public participation, review by affected states, and review by the administrator that apply to permit issuance and renewal.
D. The control officer shall process the majority of significant permit revision applications received each calendar year within nine months of receipt of a complete permit application but in no case longer than eighteen months. Applications for which the control officer undertakes accelerated processing under Section 17.12.220 shall not be included in this requirement.
