Abstract : Supplement 1 to the Final Environmental Impact Statements for improving the Oakland Outer and Oakland Inner harbor channels. Channels would be widened in some areas and deepened to -42 feet MLLW. Sediment accumulation at the selected in-Bay disposal site and adjacent to Alcatraz Island has required the consideration of other disposal sites and disposal alternatives. The selected plan would remove 6.5 million cubic yards of material from the Federal Channels. An additional .5 million cubic yards will be removed from the berthing areas by the local sponsor. Disposal of the dredged sediment will be at an ocean disposal site to be approved by the Environmental Protection Agency (EPA). The proposed site is located at a depth of 300' and is approximately 30 nautical miles from the Golden Gate Bridge (haul distance). The SEIS uses the criteria established by the Marine Protection Research and Sanctuaries Act in selecting the appropriate ocean disposal site for use under Section 103 of the Act.
