25.3. All failures resulting from landslides or slope failures must be corrected immediately if they significantly affect the safety or design capacity of the dam or its appurtenances. Failures must be reported to the Secretary.

25.4. Routine inspections shall be made of all hydraulic structures to insure operation. Special inspection shall be conducted whenever a significant flow through the structures has occurred.

25.5. All pipes must be repaired or replaced when damaged, distorted or otherwise fail to function properly according to the approved design.

25.6. Leakage through joints, fissures, cracks through or under the spillway channel shall be immediately investigated and repaired.
