9VAC5-80-1955. 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 9VAC5-80-1945 or as administrative amendments under 9VAC5-80-1935.
2. Significant amendment procedures shall be used for those permit amendments that meet any 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 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, but are not limited to, an emissions cap assumed to avoid classification as a modification under 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 9VAC5-80-1775 shall apply to requests made under this section.
D. The department will normally take final action on significant permit amendments within 180 days after receipt of a complete request. The department 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 department under subsection D of this section.
