Appendix N to report dated Feb 77, AD-A037 727.
In April 1972, the San Francisco District of the United States Army Corps or Engineers initiated a study to quantify the impact of dredging and dredged sediment disposal operations on the environment of San Francisco Bay and Estuary. The study has generated factual data, based on field and laboratory studies, needed for the Federal, State and local regulatory agencies to evaluate present dredging policies and alternative disposal methods. The study was set up to isolate the questions regarding the environmental impact of dredging operations and to provide answers at the earliest date. The study was organized to investigate (a) the factors associated with dredging and the present system of aquatic disposal in the Bay, (b) the condition of the pollutants (biogeochemical), (c) alternative disposal methods, and (d) dredging technology. The study elements were intended first, to identify the problems associated with dredging and disposal operations and, second, to address the identified problems in terms of mitigation and/or enhancement. The division into separate but inter-related study elements provided a greater degree of expertise and flexibility in the Study. Since the publication of the Main Report in February 1977, several miscellaneous studies dealing with dredging were conducted in the Bay. Although the studies were not part of the Dredge Disposal Study, they have been gathered together to form this appendix in order to make the basic data available. (Author).
