<br />The dam owner should designate a person who has the authority to make <br />needed decisions and authorize immediate expenditures so that repair work will <br />not be delayed. <br /> <br />This section should identify sources of repair equipment, materials, and <br />labor; engineering expertise; and underwater examiners for use during an <br />emergency. The materials portion should include sources for clay, sand, <br />gravel, stone, riprap, sandbags, cement, plastic sheeting, etc. The <br />anticipated need for the above items (equipment, materials, etc.) should be <br />evaluated for each dam and the specific needs and the exact location of each <br />of these items should be stated. <br /> <br />At some dams, it is desirable to stockpile suitable construction <br />materials for emergency use. The amounts and type of construction materials <br />needed for emergency repairs should be determined on the basis of the <br />structural, foundation, and other characteristics of the dam, design and <br />construction history, and history of prior problems. <br /> <br />I <br />j <br /> <br />Prior arrangements for use of materials, labor, and equipment should be <br />made if they will not be at the dam site. <br /> <br />D. Notification and Coordination <br /> <br />1. General. A mandatory first step in the entire notification chain of <br />events is the first identification that there is or could be a problem at the <br />dam as stated in Section II B. The chain of events usually proceeds from the <br />owner, to a local or state government, who, in turn, contacts local police <br />and/or civil defense groups. They may contact local news media, and finally <br />the public who are expected to take some specific actions such as evacuation. <br />The National Weather Service (NWS) has the general responsibility for issuing <br />flood warnings. Therefore, the plan should include its notification of any <br />pending or actual dam failure so that NWS facilities could be used to help <br />disseminate the warnings. The details of the specific steps and <br />responsibilities of each member in this chain of notification and the expected <br />response must be clearly defined in the plan and should be prioritized. (See <br />Sections I-F2 and I-F3.) <br /> <br />2. Emergency Notification and Methods. The responsibility for notifying <br />officials of a dam emergency should be determined. For a slowly developing <br />failure, the owner may wish to reserve this responsibility for management. <br />For an imminent or actual failure, this responsibility may have to be <br />delegated to the dam operator or local official who can quickly evaluate the <br />seriousness of the problem. The responsibility should be clearly outlined in <br />the plan. The method of notification should ensure that the message can be <br />delivered. Primary and backup communication links should be established which <br />offer reliable operation in the extreme flood, and earthquake situation which <br />could cause dam failure. <br /> <br />3. Responsibility. Responsibility for the decision to proceed with the <br />warning and evacuation of affected occupants generally rests with local and <br />State authorities. In addition to residents, affected area occupants may also <br /> <br />12 <br />
