Book Description
“The proposed new sump location would be finalized after the Corps has received all required environmental clearances, and assuming that the Corps makes a Finding of No Significant Impact (FONSI) for the Proposed Action. The Corps is the lead federal agency for this SEA and was also the lead agency for the original EA.” – From the Executive Summary, Page ii.

Book Description
The United States Army Corps of Engineers (USACE) and the San Francisco Bay Regional Water Quality Control Board (Regional Water Board) have prepared a Draft Environmental Assessment (EA)/ Environmental Impact Report (EIR) to address the potential environmental effects of the maintenance dredging of federal navigation channels in San Francisco Bay and the associated placement of dredged materials from 2015 to 2024. The USACE proposes to continue maintenance dredging of the federal navigation channels in San Francisco Bay to maintain the navigability of the channels. The Regional Water Board proposes to issue a Clean Water Act Section 401 water quality certification, and may also issue waste discharge requirements, for USACE's continued maintenance dredging operations in San Francisco Bay. The Draft EA/EIR evaluates in detail the potential environmental impacts of four alternatives: the No Action/No Project Alternative, the Proposed Action/Project, and two reduced hopper dredge use alternatives. The analysis will support decision making by USACE, the Regional Water Board, and other agencies regarding implementation of the proposed project, and will satisfy compliance with the National Environmental Policy Act, the California Environmental Quality Act, and other pertinent laws and regulations. Additionally, for those maintenance dredging projects that involve discharge of dredged or fill material into waters of the United States, the EA/EIR is intended to serve as the Section 404(b)(1) analysis for maintenance dredging in compliance with the Clean Water Act. Under NEPA, USACE determined that the proposed activity would not significantly affect the quality of the physical, biological, and human environment under any of the alternatives. The USACE's Draft Finding of No Significant Impact is included with the Draft EA/EIR. Under CEQA, the Regional Water Board determined that the No Action/ No Project Alternative and Proposed Action/Project would have significant project and cumulative impacts to delta smelt and longfin smelt from entrainment. The Regional Water Board determined that these impacts would be reduced to less than significant under the reduced hopper dredge use alternatives with minimization of hopper dredge use, implementation of the minimization measures, and compensatory mitigation proposed under these alternatives.

Book Description
"This environmental assessment (EA) addresses the environmental impacts of modifying the current dredged material placement network to include dredged material placement actions at Rice Island and outside the Federal Navigation Channel (FNC) near Howard Island. The objective of these actions is to improve overall efficiency and strategic management of the Columbia River Federal Navigation Channel Operations & Maintenance (CR FNC O & M) program and allow for greater flexibility, which will minimize impacts to the terrestrial and aquatic environment."

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.
