Basic Considerations for Preparing EAPsdam owners to coordinate with the appropriate emergency management authorities and provideinformation from dam inundation studies that can assist with evacuation planning.Dam owners should also include procedures in the EAP for ensuring that emergencymanagement authorities are provided with timely and accurate information on dam conditionsduring an incident. This information will help agencies make the appropriate decisions onevacuations.Dam emergency evacuation plans should bedeveloped before an incident occurs. Theplans are recommended to be based on aworst-case scenario and to address thefollowing: Initiation of emergency warningsystems Pre-incident planning Identification of critical facilities andshelteringPlanning session Evacuation procedures, includingflood wave travel time considerations (e.g., evacuation of special needs populations, liftingevacuation orders) Distance and routes to high ground Traffic control measures and traffic routes Potential impact of weather or releases on evacuation routes such as flooded portions of theevacuation route before the dam incident occurs Vertical evacuation/sheltering in place Emergency transportation Safety and security measures for the perimeter and affected areas Re-entry into affected areasE. Document Control and Protection of Critical InformationThe dam owner should develop an EAP distribution list for all those who would be involved inimplementing the EAP. The list must be reviewed and updated as part of updates to the EAP.Each copy of the EAP that is distributed should be controlled by copy number and a noticerequesting that other copies of the EAP not be made. When outdated EAPs have been replaced intheir entirety with new versions, the dam owner should request that the outdated controlledcopies be returned to the owner or otherwise ensure they are securely destroyed to preventFederal Guidelines for Emergency Action Planning for Dams I-6
Basic Considerations for Preparing EAPsmisuse. If EAPs are made available electronically, care should be taken to ensure that documentcontrol is maintained, such as through the use of a secure web portal accessible only to theentities on the established distribution list.To protect critical information, including but not limited to technical data and personal contactinformation, dam owners should consider maintaining a redacted copy of the EAP. The redactedcopy made available to the public upon request should not contain, for example, detailedtechnical data or contact information of individuals participating in the EAP. Dam owners mayalso wish to limit the technical information provided to external entities participating in the EAP.Decisions about what to include in the redacted copy should be made by those participating inthe EAP.F. Maintaining an EAPAfter the EAP has been developed, approved, and distributed, continual reviews and updatesmust be performed. Without periodic maintenance, the EAP will become outdated andineffective.The EAP should be updated promptly to address changes in personnel and contact information,significant changes to the facility, or emergency procedures. The EAP should be reviewed atleast annually for adequacy and updated as needed. Even if no revisions are necessary, thereview should be documented.The review should include an evaluation of any changes in flood inundation areas, downstreamdevelopments, or in the reservoir and a determination of whether any revisions, includingupdates to inundation maps, are necessary. Appendix A contains an EAP review checklist.The EAP should be updated promptly with the outcome of any exercises, including periodicreviews and verifications of personnel and contact information from Notification Flowcharts andcontact lists. Any changes to the dam and/or inundation zone should be reviewed because thechanges may affect the inundation maps. Maps should be changed as soon as practicable andnoted in the EAP.Once the EAP has been revised, the updated version (or only the affected pages in minorupdates) should be promptly distributed to those on the distribution list. Placing EAPs in loose-leaf binders may simplify the process of removing and replacing outdated pages when updatesare made. Including the date of the EAP or the date of the current revision on each page will helpto ensure that users have the most current version. It is recommended that the entire EAP bereprinted as necessary and distributed to all plan holders to ensure that all updates have beenincluded in the documents.Federal Guidelines for Emergency Action Planning for Dams I-7
