A. A permit revision is required whenever the applicant proposes substantive changes to the design, terms or conditions of a project from that which is approved in the permit. Changes are substantive if they materially alter the project in a manner that relates to its conformance to the terms and conditions of the permit, the SMP or the SMA. Changes which are not substantive in effect do not require approval of a revision.

B. Permit revisions shall be processed in accordance with WAC 173-27-100.

C. If the revision involves a shoreline variance or conditional use which was conditioned by Ecology, the revision must be reviewed and approved by Ecology under the SMA.

D. Revisions to permits under WAC 173-27-100 shall not be used to extend the original permit time requirements or to authorize substantial development after the time limits of the original permit.
