Current through Register Vol. 41, No. 3, September 23, 2024

A. Significant modification procedures shall be used for applications requesting permit modifications that do not qualify as minor permit modifications under 9VAC5-80-210 or 9VAC5-80-220 or as administrative amendments under 9VAC5-80-200. Significant modification procedures shall be used for those permit modifications that:

1. Involve significant changes to existing monitoring, reporting, or recordkeeping requirements in the permit, such as a change to the method of monitoring to be used, a change to the method of demonstrating compliance or a relaxation of reporting or recordkeeping requirements.

2. Require or change a case-by-case determination of an emission limitation or other standard, or a source-specific determination for temporary sources of ambient impacts made under 9VAC5-40 (Existing Stationary Sources), 9VAC5-50 (New and Modified Stationary Sources), or 9VAC5-60 (Hazardous Air Pollutant Sources), or a visibility or increment analysis carried out under this chapter.

3. Seek to establish or change a permit term or condition for which there is no corresponding underlying applicable federal requirement and that the source has assumed to avoid an applicable federal requirement to which the source would otherwise be subject. Such terms and conditions include:
a. A federally enforceable emissions cap assumed to avoid classification as a Title I modification.

b. An alternative emissions limit approved pursuant to regulations promulgated under § 112(i)(5) of the federal Clean Air Act (early reduction of hazardous air pollutants).

B. An application for a significant permit modification shall meet the requirements of 9VAC5-80-80 and 9VAC5-80-90 for permit issuance and renewal for the modification proposed and shall include the following:

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

2. A suggested draft permit prepared by the applicant.

3. Completed forms for the department to use to notify the administrator and affected states as required under 9VAC5-80-290.

C. The provisions of 9VAC5-80-290 shall be carried out for significant permit modifications in the same manner as they would be for initial permit issuance and renewal.

D. The provisions of 9VAC5-80-270 shall apply to applications made under this section.

E. The department shall take final action on significant permit modifications within nine months after receipt of a complete application.

F. The owner shall not make the change applied for in the significant modification application until the modification is approved by the department under subsection E of this section.

G. The provisions of 9VAC5-80-140 shall apply to changes made under this section.
