Ariz. Admin. Code § 18-2-319

Current through Register Vol. 30, No. 25, June 21, 2024

Section R18-2-319 - Minor Permit Revisions

A. Minor permit revision procedures may be used only for those changes at a Class I source that satisfy all of the following:

1. Do not violate any applicable requirement;

2. Do not involve substantive changes to existing monitoring, reporting, or recordkeeping requirements in the permit;

3. Do not require or change a case-by-case determination of an emission limitation or other standard, or a source-specific determination of ambient impacts, or an analysis of impacts on visibility or maximum increases allowed under R18-2-218;

4. Do not seek to establish or change a permit term or condition for which there is no corresponding underlying applicable requirement and that the source has assumed in order to avoid an applicable requirement to which the source would otherwise be subject. The terms and conditions include:

a. A federally enforceable emissions cap that the source would assume to avoid classification as a modification under any provision of Title I of the Act; and

b. An alternative emissions limit approved under regulations promulgated under the section 112(i)(5) of the Act.

5. Are not modifications under any provision of Title I of the Act;

6. Are not changes in fuels not represented in the permit application or provided for in the permit;

7. Are not minor NSR modifications subject to R18-2-334; and

8. Are not required to be processed as a significant permit revision under R18-2-320.

B. Minor permit revision procedures shall be used for the following changes at a Class II source:

1. A change that triggers a new applicable requirement if all of the following apply:

a. The change is not a minor NSR modification subject to R18-2-334;

b. A case-by-case determination of an emission limitation or other standard is not required; and

c. The change does not require the source to obtain a Class I permit.

2. A change that increases emissions above the permitted level unless the increase otherwise creates a condition that requires a significant permit revision;

3. A change in fuel from fuel oil or coal, to natural gas or propane, if not authorized in the permit;

4. A change that results in emissions subject to monitoring, recordkeeping, or reporting under R18-2-306(A)(3),(4), or (5) and that cannot be measured or otherwise adequately quantified by monitoring, recordkeeping, or reporting requirements already in the permit;

5. A decrease in the emissions permitted under an emissions cap unless the decrease requires a change in the conditions required to enforce the cap or to ensure that emissions trades conducted under the cap are quantifiable and enforceable; and

6. Replacement of an item of air pollution control equipment listed in the permit with one that does not have the same or better efficiency.

C. As approved by the Director, minor permit revision procedures may be used for permit revisions involving the use of economic incentives, marketable permits, emissions trading, and other similar approaches, to the extent that the minor permit revision procedures are explicitly provided for in an applicable implementation plan or in applicable requirements promulgated by the Administrator.

D. An application for minor permit revision shall be on the standard application form provided under R18-2-304(B) and include the following:

1. A description of the change, the emissions resulting from the change, and any new applicable requirements that will apply if the change occurs;

2. For Class I sources, and any source that is making the change immediately after it files the application, the source's suggested draft permit;

3. Certification by a responsible official, consistent with standard permit application requirements, that the proposed revision meets the criteria for use of minor permit revision procedures and a request that the procedures be used;

E. EPA and affected state notification. For Class I permits, within five working days of receipt of an application for a minor permit revision, the Director shall notify the Administrator and affected states of the requested permit revision in accordance with R18-2-307.

F. For Class I permits, the Director shall not issue a final permit revision until after the Administrator's 45-day review period or until the Administrator has notified the Director that the Administrator will not object to issuance of the permit revision, whichever is first, although the Director may approve the permit revision before that time. Within 90 days of the Director's receipt of an application under minor permit revision procedures, or 15 days after the end of the Administrator's 45-day review period, whichever is later, the Director shall do one or more of the following:

1. Issue the permit revision as proposed,

2. Deny the permit revision application,

3. Determine that the proposed permit revision does not meet the minor permit revision criteria and should be reviewed under the significant revision procedures, or

4. Revise the proposed permit revision and transmit to the Administrator the new proposed permit revision as required in R18-2-307.

G. The source may make the change proposed in its minor permit revision application immediately after it files the application. After a Class I source makes a change allowed by the preceding sentence, and until the Director takes any of the actions specified in subsection (F), the source shall comply with both the applicable requirements governing the change and the proposed revised permit terms and conditions. During this time period, the Class I source need not comply with the existing permit terms and conditions it seeks to modify. However, if the Class I source fails to comply with its proposed permit terms and conditions during this time period, the existing permit terms and conditions it seeks to revise may be enforced against it.

H. The permit shield under R18-2-325 shall not extend to minor permit revisions.

I. Notwithstanding any other part of this Section, the Director may require a permit to be revised under R18-2-320 for any change that, when considered together with any other changes submitted by the same source under this Section or R18-2-317.02 over the life of the permit, do not satisfy subsection (A) for Class I sources or subsection (B) for Class II sources.

J. The Director shall make available to the public monthly summaries of all applications for minor permit revisions.
