Current through Register Vol. 50, No. 11, November 20, 2024
Section III-725 - Emergency Preparedness PlanA. An Emergency Preparedness Plan is required for all dams and reservoirs both existing and new construction. The plan will comply with the guidelines of the current issue of Louisiana's Emergency Action Plan Guidelines, available from the Director of Public Works and Flood Control, and shall be submitted as a necessary component of the maintenance and operating procedures and as a condition of the permitting process. It is the owner's responsibility to assure that the provisions of the Emergency Action Plan are implemented in the event of an emergency situation.B. A breach analysis is required to develop the emergency preparedness plan. The breach analysis will establish the magnitude of the inundated area (inundation map), peak flood elevations and arrival times of the peak flood elevations at critical locations. The worst case scenario breaching event will be somewhere between the "sunny day" breach and that event above which a breach of the dam does not increase hazard to downstream interests. If the dam owner prefers to perform only one breach analysis rather than performing incremental analyses to discover the worst case scenario breaching event, he may perform a breach analysis where the tail water is at the average annual elevation and the reservoir is at maximum design surcharge.La.
