This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Corps of Engineers and published by . This book was released on 2015 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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."

This book was released on 1982 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance dredging is proposed for the Black Rock Harbor-Cedar Creek Federal navigation channel and the western portion of the Bridgewater Harbor Anchorage Area. Approximately 10,000 to 15,000 cubic yards (c.y.) of sediment from the central section of the channel would be dredged by a hydraulic dredge and deposited onto an intertidal mudflat area which would be confined by a steel bulkhead. An upland-intertidal marsh habitat would be created for a proposed field research program (Field Verification Program (AFVP)) which would study the long term impacts of this type of disposal. The remainder of the sediments derived from the central section of the channel(70,000 c.y.) would be dredged by clamshell dredge and deposited in an uncapped mound at the Central Long Island Sound Disposal Site, near New Haven. This deposit would also be studied under the FVP. The remainder of the sediments from the upper and lower sections of the channel, sediment from private dredging areas, and the sediments from the Bridgeport Harbor Anchorage Area would be disposed at a separate capped mound at the Central Long Island Sound Disposal area. The FVP study may include a comparison of the uncapped and capped mounds.

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.
