In the event of a serious disagreement between a Federal and State agency regarding whether a listed or unlisted federal license or permit activity is subject to the federal consistency requirement, either party may request the OCRM mediation or Secretarial mediation services provided for in subpart G of this part; notice shall be provided to the applicant. The existence of a serious disagreement will not relieve the Federal agency from the responsibility for withholding approval of a license or permit application for an activity on an approved management program list (see §930.53) or individually approved by the Director (see §930.54) pending satisfaction of the requirements of this subpart. Similarly, the existence of a serious disagreement will not prevent the Federal agency from approving a license or permit activity which has not received Director approval.
