    Many of the older dams are characterized by increased hazard potential due to downstream develop- ment and increased risk due to structural deterioration or inadequate spill- way capacity. The "Consultant Inspection Process Form" should be submitted with every owner inspection. Timeline: Within 90 days of completing the inspection, the consulting engineer on behalf of the dam owner shall submit an inspection report to the Department for review and concurrence. Preparation of inspection reports What is it: The inspection report provides a summary of the inspection findings.

    The narrative will need to include a description of deficiencies and should also note the severity of the deficiency. The consulting engineer must provide an actual due date. The consulting engineer includes recommendations for maintenance and repairs, and provides a timeline for repairs or further investigation. The "Consultant Inspection Process Form" should be submitted with every owner inspection.

    Note that every dam is unique and timelines will differ depending on its condition. In the last decade, several major dam failures have increased public awareness of the potential haz- ards caused by dams. Spe- cific remedial actions have been recommended, ranging from more de- tailed investigations to immediate repair for correction of emergency con- ditions. The consulting engineer must provide an actual due date. Many of the older dams are characterized by increased hazard potential due to downstream develop- ment and increased risk due to structural deterioration or inadequate spill- way capacity. Documentation A dam safety inspection report and supporting documentation will be prepared and sent to the Department for review.
