: This technical note summarizes the types of concerns that lead to requests for environmental windows for Federal navigation dredging projects in both marine and freshwater systems, as well as the frequencies of occurrence of these concerns among U.S. Army Corps of Engineer (USACE) Districts. The information presented is derived from responses received from a survey sent to all USACE District offices that perform operations and maintenance (O&M) dredging in either marine or freshwater environments. This note serves to update earlier surveys by LaSalle et al. (1991) for dredging operations conducted in coastal and Great Lakes areas and by Sanders and Killgore (1989) for seasonal restrictions associated with dredging operations in freshwater systems.read more

TL;DR: In this paper, a meta-analysis following a conservative approach is used to understand how dredging-related stressors, including suspended sediment, contaminated sediment, hydraulic entrainment and underwater noise, directly influence the effect size and the response elicited in fish across all aquatic ecosystems and all life-history stages.
Journal ArticleDOI
A risk-informed decision framework for setting environmental windows for dredging projects.
TL;DR: Combining risk assessment and multi-criteria decision analysis allows development of a framework for an objective process consistent with recommendations by the National Academy of Sciences for setting environmental windows.
Technical Guidelines for Environmental Dredging of Contaminated Sediments
TL;DR: In this article, the authors provide technical guidelines for evaluating environmental dredging as a sediment remedy component, which is applicable to contaminated sediment sites evaluated under various environmental laws and regulatory programs.

A framework for assessing the need for seasonal restrictions on dredging and disposal operations
TL;DR: In this paper, the authors address the general acceptability of seasonal restrictions through a compilation of available information on physical-chemical environmental alterations associated with dredging and disposal operations, and critical information regarding the effects of these alterations on principal biological resources.

Economic Impacts of Environmental Windows Associated with Dredging Operations
TL;DR: In this article, the potential economic impacts that result from compliance with requests for environmental windows (i.e., temporal constraints) on dredging operations are described, when examined in tandem with characterizations of the frequencies of windows associated with Federal dredging projects and the technical issues used to justify requests for specific environmental windows.
