Section 1570. 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 9VAC5-80-1560 or as administrative amendments under 9VAC5-80-1550.

2. Significant amendment procedures shall be used for those permit amendments that:

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 emission limitation or other standard.

c. Seek to establish or change a 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 modification subject to the new source review program or § 112 of the federal Clean Air Act.

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

d. Result from modifications subject to the 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. The provisions of 9VAC5-80-1460 shall apply to requests made under this section.

D. The board will normally take final action on significant permit amendments within 90 days after receipt of a complete request.

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.
