Book Description
This technical note describes an approach for assessing the genotoxic potential of dredged material. The use of integrated batteries of rapid and mechanistically interpretable in vitro and in vivo assays in a tiered approach is fundamental to applied toxicology. The research described here brings this approach to the testing of sediments. Work completed to date and future work will mesh to form an advanced and cost-effective methodology. The purpose of this methodology is to increase the accuracy of environmental risk assessments and facilitate making decisions concerning open-water disposal of dredged material. A great number of the contaminants typically found in dredged material are toxic to exposed organisms through effects on DNA. Such effects are usually the result of low-level chronic exposures. These effects can result in reproductive failure of organisms, impaired growth and development of offspring, and tumors (often cancerous) in vertebrates. Collectively, such effects are called 'genotoxicity' and result from damage to the genome of a cell. The damage is heritable, that is, passed on to future cell generations upon duplication of the affected cells.

Book Description
This document is intended to serve as a consistent "roadmap" for U.S. Army Corps of Engineers and U.S. Environmental Protection Agency personnel in evaluating the environmental acceptability of dredged amterial management alternatives. Specifically, its major objectives are to provide: A general technical framwork for evaluating the environmental acceptability of dredged material management, alternatives (open-water disposal, confined (diked) disposal, and beneficial uses). Additional technical guidance to augment present implementation and testing manuals for addressing the environmental acceptability of available management options for the discharge of dredged material in both ope water and confined sites. Enhanced consistency and coordination in USAC/EPA decision making in accordance with Federal environmantl statutes regulating dredged material management.

Book Description
Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.

Book Description
This Technical Note presents a brief description of a joint U.S. Army Corps of Engineers (USACE) and U.S. Environmental Protection Agency (USEPA) Technical Framework for the identification of environmentally acceptable alternatives for the management of dredged material. This Technical Note replaces the earlier Technical Note EEDPA-06-14, which should be discarded. (MM).
