Virginia Administrative Code
Title 9. Environment
Agency 25. State Water Control Board
Chapter 220. Surface Water Management Area Regulation

9VAC25-220-210. Causes for modification.

A permit may be modified, but not revoked and reissued, except when the permittee agrees or requests, when any of the following developments occur:

1. When additions or alterations have been made to the affected facility or activity which require the application of permit conditions that differ from those of the existing permit or are absent from it;

2. When new information becomes available about the operation or withdrawal covered by the permit which was not available at permit issuance and would have justified the application of different permit conditions at the time of permit issuance;

3. When a change is made in the methodology or regulations on which the permit was based;

4. When it becomes necessary to change final dates in schedules due to circumstances over which the permittee has little or no control such as acts of God, materials shortages, etc. However, in no case may a compliance schedule be modified to extend beyond any applicable statutory deadline of the Act;

5. When the department determines that minimum instream flow levels resulting from the permittee's withdrawal of water is detrimental to the instream beneficial use and that the withdrawal of water should be subject to further net limitations; and

6. When other states were not notified of the change in the permit and their waters may be affected by the withdrawal.

Statutory Authority
