A. A source with a Class II or Class III permit shall make the following changes only after the permit is revised following the public participation requirements of Section 17.13.210:
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 to or addition of an emissions unit not subject to an emissions cap that will result in a net emission increase of a pollutant greater than the significance level in Section 17.04.340(A)(211);
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 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. 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 a visibility or increment analysis; 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.
B. 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.
C. When an existing source applies for a significant permit revision to revise its permit from a Class II or Class III permit to a Class I permit, it shall submit a Class I permit application for the entire source in accordance with Section 17.12.010. The control officer 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 Section 17.12.060 and Section 17.13.210.
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 17.13.240(H) shall not be included in this requirement.
