(2) Seismicity. Identify any seismic events that may affect the conclusions of the seismicity analyses of record and evaluate the effect on the safety and stability of project works.
(3) Modifications to project works. Identify any modifications made to project works and evaluate the performance thereof with respect to the design intent.
(4) Methods of operation. Describe any changes to standard operating procedures, equipment available for project operation, and evaluate the effect on the safety and stability of project works.
(5) Results of special inspections. Summarize the findings of any special inspections (dive inspection, rope-access gate inspection, toe drain inspection, etc.), if any.
(6) Previous recommendations. List and document the status of recommendations made by the independent consultant(s) in the Previous Part 12D Report, and any earlier recommendations that remained incomplete at the time of the Previous Part 12D Report.
