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.

This publication is a summary of good practice on the use of rock in engineering works for rivers, coasts and seas. It has incorporated all the significant advances in knowledge that have occured over the past 10-15 years.

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.

The adverse effects of construction on the coastal and marine environment are well publicised and understood by regulators, the industry and the general public. The impact of poor working practices can be extensive, given the often sensitive nature of the habitats and the importance of this region for human activities and interests. implications is becoming increasingly the responsibility of front-line staff. This greater accountability at the site level demands higher standards of environmental awareness and education, through trained and experienced personnel who can effectively manage environmental issues with the speed and urgency that they often require. avoiding and mitigating the effects of poor environmental practice on coastal and marine construction projects. contract supervisors/resident engineers; and project managers. construction experience from the young site engineer to the experienced manager. It can also be used as a training aid or refrence book, to provide site personnel with the correct information to hand for dealing with key environmental and management issues.

April 2018 Full COLOR 8 1/2 by 11 inches The Public Assistance Program and Policy Guide provides an overview of the Presidential declaration process, the purpose of the Public Assistance (PA) Program, and the authoritiesauthorizing the assistance that the Federal Emergency Management Agency provides under the PA Program. It provides PA policy language to guide eligibility determinations. Overarching eligibility requirements are presented first and are not reiterated for each topic. It provides a synopsis of the PA Program implementation process beginning with pre-declaration activities and continuing through closeout of the PA Program award. When a State, Territorial, or Indian Tribal Government determines that an incident may exceed State, Territorial, Indian Tribal, and local government capabilities to respond, it requests a joint Preliminary Damage Assessment (PDA) with the Federal Emergency Management Agency (FEMA). Federal, State, Territorial, Indian Tribal, local government, and certain private nonprofit (PNP) organization officials work together to estimate and document the impact and magnitude of the incident. Why buy a book you can download for free? We print the paperback book so you don't have to. First you gotta find a good clean (legible) copy and make sure it's the latest version (not always easy). Some documents found on the web are missing some pages or the image quality is so poor, they are difficult to read. If you find a good copy, you could print it using a network printer you share with 100 other people (typically its either out of paper or toner). If it's just a 10-page document, no problem, but if it's 250-pages, you will need to punch 3 holes in all those pages and put it in a 3-ring binder. Takes at least an hour. It's much more cost-effective to just order the bound paperback from Amazon.com This book includes original commentary which is copyright material. Note that government documents are in the public domain. We print these paperbacks as a service so you don't have to. The books are compact, tightly-bound paperback, full-size (8 1/2 by 11 inches), with large text and glossy covers. 4th Watch Publishing Co. is a HUBZONE SDVOSB. https: //usgovpub.com Buy the paperback from Amazon and get Kindle eBook FREE using MATCHBOOK. go to https: //usgovpub.com to learn how
