Available in PDF, EPUB and Kindle. Book excerpt: Evaluating the potential environmental consequences associated with dredging and dredged material disposal is a difficult task. Scientific advancements have made possible the collection of large amounts of complex technical information. The dredged material manager must often rely on "best professional judgement" to weigh and balance among multiple and sometimes conflicting lines of evidence to reach a decision, and each decision involves a finite level of uncertainty. How best to utilize this complex technical information and what tools are available for developing risk-based estimates and evaluating uncertainty for the dredging program were the focus of the workshop discussions reported herein. The workshop was attended by 78 invitees representing Corps field elements, other Federal agencies, industry, and academia. Participants represented a broad range of stakeholders and included permit applicants, dredged material managers, and risk assessors.

Book excerpt: The report presents an assessment of the dredge spoil disposal problem and outlines a research program designed to provide needed information concerning current and potential spoil disposal practices. The report format is intended to reflect the two basic objectives of the report. Section A is directed toward management level review and presents (a) pertinent background information concerning the dredge spoil disposal problem and the current study, (b) conclusions and recommendations resulting from the problem assessment phase of the study, and (c) an outline of the recommended research program. Section B provides an objective assessment of the nationwide problem in sufficient detail to permit meaningful technical review by other interested personnel within and outside the Corps. Section C has been included to show a total-problem organizational structure which is being used to guide the development of the detailed research plan.

Download or read book Environmental Aspects of Dredging written by R. N. Bray and published by CRC Press. This book was released on 2008-03-10 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This report synthesizes data from the U.S. Army Corps of Engineers' Dredged Material Research Program, Task 1D. Task 1D consisted of six research projects (work units) that investigated the direct and indirect effects of dredging and disposal of dredged material on aquatic organisms. Determination of potential environmental effects of dredging and disposal, in spite of research conducted to date, is still in preliminary stages due to the multiplicity of variables involved. Bioavailability of sediment-sorbed heavy metals is low. Release of sediment-associated heavy metals and their uptake into organism tissues have been found to be the exception rather than the rule. Research results suggest that there is little or no correlation between the bulk sediment content of heavy metals and environmental impact. Oil and grease residues, like the heavy metals, seem tightly bound to sediment particles and accumulation of these residues by organisms is minimal. The diversity of variables that have the potential for direct and indirect effects on acquatic life argues for an integrated, whole-sediment bioassay, using sensitive test organisms. Such a procedure is currently under development by the Environmental Protection Agency and the Corps of Engineers and should uncover site-specific toxicity problems which can be addressed by appropriate chemical testing and biological evaluation of dredged material.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical note describes the development of Dredging Risk Assessment Modeling Applications (DRAMA) for evaluation of the no-action scenario and the impacts of dredging operations without consideration of disposal. Implementation templates for these scenarios use existing dredging models to characterize exposure for the evaluation of potential human health and ecological risk. The models selected have been incorporated into the Framework for Risk Analysis in Multimedia Environmental Systems (FRAMES), a part of the Army Risk Assessment Modeling System (ARAMS).

This book was released on 2007-10-30 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the nation's estuaries, lakes and other water bodies contain contaminated sediments that can adversely affect fish and wildlife and may then find their way into people's diets. Dredging is one of the few options available for attempting to clean up contaminated sediments, but it can uncover and re-suspend buried contaminants, creating additional exposures for wildlife and people. At the request of Congress, EPA asked the National Research Council (NRC) to evaluate dredging as a cleanup technique. The book finds that, based on a review of available evidence, dredging's ability to decrease environmental and health risks is still an open question. Analysis of pre-dredging and post-dredging at about 20 sites found a wide range of outcomes in terms of surface sediment concentrations of contaminants: some sites showed increases, some no change, and some decreases in concentrations. Evaluating the potential long-term benefits of dredging will require that the U.S. Environmental Protection Agency step up monitoring activities before, during and after individual cleanups to determine whether it is working there and what combinations of techniques are most effective.
