This document provides guidance to help dam owners, in coordination with emergency management authorities, effectively develop and exercise emergency action plans for dams. The purpose of the guidance in this document is to meet that need. This document is an update of FEMA P-64, Federal Guidelines for Dam Safety: Emergency Action Planning for Dam Owners (2004).
This Dam Incident Planning Guide supports state, local, tribal, and territorial emergency managers in planning for dam incidents and failures by summarizing the concepts that a community should consider when creating dam incidentspecifc elements of local emergency operations plans. This guide builds on Comprehensive Preparedness Guide (CPG) 101: Developing and Maintaining Emergency Operations Plans.1 It also provides guidance for dam owners and operators on how to engage with emergency managers prior to an incident to ensure a well-coordinated response. Appendix A provides a general template for a community dam incident plan that can be adapted to meet each communitys needs.
These guidelines encourage strict safety standards in the practices and procedures employed by federal agencies or required of dam owners regulated by the federal agencies. The guidelines provide the most complete and authoritative statement available of the desired management practices for promoting dam safety and the welfare of the public. The guidelines apply to federal practices for dams with a direct federal interest; the guidelines do not attempt to establish technical standards and are not intended to supplant or confict with state or local government responsibilities for the safety of dams under their jurisdiction.
This document provides guidelines for implementing risk-informed decision making in a dam safety program. The intended audience is federal agencies that own or regulate dams. The guidelines could also be applied to non-federally owned or regulated dams that can impact federally owned or regulated facilities; however, this would require the cooperation and involvement of the non-federal dam owner.
The purpose of this document is to provide dam safety professionals with guidance on how to prepare dam breach inundation modeling studies and conduct mapping that can be used for multiple purposes, including dam safety, hazard mitigation, consequence evaluation, and emergency management including developing emergency action plans. This guidance is intended to provide a consistent approach that can be applied across the country.
This 2019 study of approximately 30 guidance documents, project initiatives and standards from around the world was undertaken by GMG and Cambrian College. It offers an understanding of existing practices and initiatives covering mine tailings throughout the global mining industry.
There is great variance in the effectiveness of state dam safety programs. Although some of this variance may be appropriate as each state must address its dam safety needs and responsibilities in its own way, some state programs are not considered adequate. Many unsafe dams also have been identifed and any required remedial action has not been implemented. The Model State Dam Safety Program was frst developed in 1987, updated in 1997, and updated again in 2006 to assist state offcials in initiating or improving their state programs. The document outlines the key components of an effective dam safety program and provides guidance on the development of more effective and sustainable state programs to eliminate the risks created by unsafe dams.
These guidelines provide thorough and consistent procedures for selecting and accommodating infow design foods (IDFs), the food fow above which the incremental increase in water surface elevation downstream due to the failure of a dam or other water retaining structure no longer presents an unacceptable additional downstream threat. These guidelines are not intended to provide a complete manual of all procedures for estimating IDFs; the selection of procedures is dependent upon available hydrologic data and individual watershed characteristics.
The purpose of this technical manual for dam owners is to advance awareness of the characteristics and seriousness of dam safety problems associated with tree and woody vegetation growth impacts on earthen dams, provide a higher level of understanding of dam safety issues by reviewing current damage control policies, provide state-of-practice guidance for remediation design considerations associated with damages associated with tree and woody vegetation growth on earthen dams, and to provide rationale and state-of-practice techniques and procedures for management of desirable and undesirable vegetation on earthen dams.
This technical manual provides procedures and guidance for best practices for the design, construction, problem identifcation and evaluation, inspection, maintenance, renovation, and repair associated with conduits through embankment dams. The technical manual is intended for use by personnel familiar with embankment dams and conduits, such as designers, inspectors, construction oversight personnel, and dam safety engineers. The DVD format includes an extensive collection of additional reading references.
