consulted. Only once the emergency is terminated shall Elk River Municipal Utilities utilize the notification flowchart so that all notified parties are made aware of the end of the emergency condition. After termination of an emergency, a qualified engineer should inspect the dam for any damage. A post-disaster review of the inspection will be held with the DNR State Dam Safety Engineer to ensure that the dam is in compliance with state standards. This review may result in formal orders issued to the dam owner and may require the submittal of plans and specifications for repair. A follow-up evaluation should be held as soon as possible following an emergency event. This evaluation shall address events prior to, during, and following the emergency; significant actions taken by each participant; what improvements would be desirable for future emergencies; and all deficiencies found in procedures, materials, equipment, manpower, leadership, and funding. A post-emergency report should be prepared by the Dam Owner, issued to the DNR State Dam Safety Engineer, and distributed to all organizations that participated in or have a direct interest in the emergency. Any changes deemed necessary for the EAP will be made by the EAP coordinator, and an updated EAP—including an updated Approval sheet—will be distributed to all holders of the EAP. B. EAP Coordinator Responsibility The City of Elk River shall serve as the EAP coordinator. As the EAP coordinator, The City of Elk River is responsible for preparing revisions to the EAP, distributing the EAP to involved agencies and parties, establishing EAP training seminars for dam tenders and other involved parties, and coordinating EAP exercises. The City of Elk River is the EAP contact should any of the involved parties have questions about the plan. VI. Preparedness A. Surveillance The Elk River Dam is not operated remotely- everything is manual. Conditions indicating a possible emergency situation and the potential for dam failure are outlined in Table 2, and can be observed via daily inspection. The dam tenders must also be able to identify potentially dangerous flow conditions. Potential flood conditions are characterized by: extended periods of greater than average precipitation or combined melting periods greater than average precipitation; and rapidly increasing headwater levels (greater than 2 inches increase per hour). Factors which require consideration in light of potential emergency flood situations include: initial water elevation and gate operation; previous weather history; and predicted weather. 170
