Section R18-2-320 - Significant Permit Revisions
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 R18-2-319(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 recordkeeping permit terms or conditions shall follow significant revision procedures.
B. A source with a Class II permit shall make the following changes only after the permit is revised following the public participation requirements of R18-2-330:
1. Establishing or revising a voluntarily accepted emission limitation or standard as described by R18-2-306.01 or R18-2-306.02, except a decrease in the limitation authorized by R18-2-319(B)(5);
2. Making any change in fuel not authorized by the permit and that is not fuel oil or coal, to natural gas or propane;
3. A change that is a minor NSR modification subject to R18-2-334;
4. A change that relaxes monitoring, recordkeeping, or reporting requirements, except when the change results from:
a. Removing equipment that results in a permanent decrease in actual emissions, if the source keeps onsite records of the change in a log that satisfies Appendix 3 of this Chapter and if the requirements that are relaxed are present in the permit solely for the equipment that was removed; or
b. A change in an applicable requirement.
5. A change that will cause the source to violate an existing applicable requirement including the conditions establishing an emissions cap;
6. A change that will require any of the following:
a. A case-by-case determination of an emission limitation or other standard;
b. A source-specific determination of ambient impacts, or an analysis of impacts on visibility or maximum allowable increases allowed under R18-2-218; or
c. A case-by-case determination of a monitoring, recordkeeping, and reporting requirement.
7. A change that requires the source to obtain a Class I permit.
C. Any modification to a major source 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 permit revision procedures and any rules adopted under A.R.S. § 49-426.03.
D. Significant permit revisions shall meet all requirements of this Article for applications, public participation, review by affected states, and review by the Administrator that apply to permit issuance and renewal. Notwithstanding R18-2-330(C), the Director may provide notice for changes requiring a significant permit revision solely under subsection (B)(2), (4) or (6)(c) by posting a notice on the Department's web site, sending e-mails to persons who have requested electronic notification of the Department's proposed air quality permit actions and by mailing a copy of the notice as provided in R18-2-330(C)(1).
E. When an existing source applies for a significant permit revision to revise its permit from a Class II permit to a Class I permit, it shall submit a Class I permit application in accordance with R18-2-304. The Director shall issue the entire permit, and not just the portion being revised, in accordance with Class I permit content and issuance requirements, including requirements for public, affected state, and EPA review, contained in R18-2-307 and R18-2-330.
