9VAC5-80-1290. Significant Amendment Procedures.

A. The criteria for use of significant amendment procedures are as follows:

1. Significant amendment procedures shall be used for requesting permit amendments that do not qualify as minor permit amendments under 9VAC5-80-1280 or as administrative amendments under 9VAC5-80-1270.

2. Significant amendment procedures shall be used for those permit amendments that meet any one of the following criteria:

a. Involve significant changes to existing monitoring, reporting, or recordkeeping requirements that would make the permit requirements less stringent, 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.

b. Require or change a case-by-case determination of an emissions limitation or other requirement.

c. Seek to establish or change a minor NSR permit term or condition (i) for which there is no corresponding underlying applicable regulatory requirement and (ii) that the source has assumed to avoid an applicable regulatory requirement to which the source would otherwise be subject. Such terms and conditions include:

(1) An emissions cap assumed to avoid classification as a project subject to the new source review program or as a modification under § 112 of the federal Clean Air Act; and

(2) An alternative emissions limit approved pursuant to regulations promulgated under § 112(i)(5) of the federal Clean Air Act.

3. Significant amendment procedures may not be used to bypass the public participation requirements in 9VAC5-80-1170 for an application for a project that would be subject to the minor new source review program.

B. A request for a significant permit amendment shall include a description of the change, the emissions resulting from the change, and any new applicable regulatory requirements that will apply if the change occurs. The applicant may, at the applicant's discretion, include a suggested draft permit amendment.

C. At the discretion of the board, the provisions of 9VAC5-80-1170 D and E shall apply to requests made under this section if the emissions unit subject to the request under this section was subject to review in any previous permit application that was subject to 9VAC5-80-1170.

D. The board will normally take final action on significant permit amendments within 90 days after receipt of a complete request. If a public hearing is required, processing time for a permit amendment is normally 180 days following receipt of a complete request except in cases where direct consideration of the request by the board is granted pursuant to 9VAC5-80-25. The board may extend this time period if additional information is needed.

E. The owner shall not make the change applied for in the significant amendment request until the amendment is approved by the board under subsection D of this section.
