Section 990. Significant amendment procedures

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

1. Significant amendment procedures shall be used for requests for permit amendments that do not qualify as minor permit amendments under 9VAC5-80-980 or as administrative amendments under 9VAC5-80-970.

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 under 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.

B. A request for a significant permit amendment shall include the following:

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

2. A suggested draft permit prepared by the applicant.

C. The provisions of 9VAC5-80-1020 shall apply to applications 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. If a public comment period is required, processing time for a request is normally 180 days following receipt of a complete request except in cases where a public hearing to provide the opportunity for interested persons to contest the request is granted pursuant to 9VAC5-80-35. 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.
