A. The following changes at a source with a Class II or Class III permit shall require a permit revision:
1. A change that triggers a new applicable requirement, violates an existing applicable requirement, or is a modification under A.R.S. § 49-401.01(24).
2. Establishment of, or change in, an emissions cap;
3. A change that will require a case-by-case determination of an emission limitation or other standard, or a source-specific determination of ambient impacts, or a visibility or increment analysis;
4. A change that results in emissions that are subject to monitoring, recordkeeping or reporting under Sections 17.13.020(A)(3), (A)(4), or (A)(5). If the emissions cannot be measured or otherwise adequately quantified by monitoring, recordkeeping, or reporting requirements already in the permit;
5. A change that will authorize the burning of used oil, used oil fuel, hazardous waste, or hazardous waste fuel, or any other fuel not currently authorized by the permit;
6. A change that requires the source to obtain a Class I permit;
7. Replacement of an item of air pollution control equipment listed in the permit with one that does not have the same or better pollutant removal efficiency;
8. Establishment or revision of a limit under Section 17.11.190;
9. Increasing operating hours or rates of production above the permitted level; and
10. A change that relaxes monitoring, recordkeeping, or reporting requirements, except when the change results:
a. From removing equipment that results in a permanent decrease in actual emissions, if the source keeps on-site records of the change in a log that satisfies Sections 17.13.110(I)(1) and (I)(2) and if the requirements that are relaxed are present in the permit solely for the equipment that was removed; or
b. From a change in an applicable requirement.
B. A source with a Class II or Class III permit may make any physical change or change in the method of operation without revising the source's permit unless the change is specifically prohibited in the source's permit or is a change described in subsection A. A change that does not require a permit revision may still be subject to requirements in Section 17.13.120.
