Welcome to the State of California

Dredging and Sediment Management

Any dredging and disposal activity in San Francisco Bay, marshes and some creeks requires a permit from the Commission. The Commission works with its federal, state and local partners in the Long Term Management Strategy for the Placement of Dredged Material in the San Francisco Bay Region (LTMS) to manage dredging and disposal activities in the Bay Area. Formed in 1990, the LTMS Program is a collaborative partnership involving the regulatory agencies, resource agencies and stakeholders working together to maximize beneficial reuse of dredged material and minimize disposal in the Bay and at the Deep Ocean Disposal Site (SFDODS). The sponsoring agencies include the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers, the State Water Board, the San Francisco Bay Regional Water Quality Control Board and BCDC.

LTMS Managment Plan 2001
The LTMS Management Plan describes the implementation of the LTMS over a twelve-year period, and how reducing in-Bay and SFDOS disposal in favor of beneficial reuse can be accomplished.

LTMS Managment Plan EIS/EIR Document
Prepared in 1998, this programmatic EIS/EIR completed the environmental compliance with the National Environmental Protection Act and the California Environmental Quality Act necessary to implement the LTMS Management Plan.

Dredged Material Management Office
The DMMO was created as part of the LTMS program to provide a “one-stop shop” for processing applications for dredging and disposal projects in the San Francisco Bay region. The DMMO cooperatively reviews sediment quality sampling plans, analyzes the results of sediment quality sampling, makes suitability determinations for disposal, offers a consolidated application that can be jointly processed for each agency’s permits for dredging and disposal projects in San Francisco Bay, the SFDODS, and beneficial reuse sites. The goal of this interagency group is to increase efficiency and coordination between the member agencies and to foster a comprehensive and consolidated approach to handling dredged material management issues. The DMMO also manages and tracks dredging and disposal projects in the region.

Two-Day Regional Sediment Management Science Workshop in April 2010
Scientist discussed sediment dynamics of San Francisco Bay Region

In 2013, BCDC received applications to mine up to 1.54 million cubic yards of sand from Central San Francisco Bay and 500,000 cubic yards from Suisun Bay and Channel. To assist the Commission, staff, stakeholders and the public in understanding the complex nature of coarse grain sediment transport, the biological community present and the connection to the immediate and greater food web, the Commission staff is hosting a Science Advisory Panel. The panel will assist Commission staff in better understanding the potential for impacts from sand mining in Central and Suisun Bay, and the likelihood of those impacts on the physical environment and the associated biological community.

Instructions for preparing the consolidated Dredging-Dredged Material Reuse/Disposal Application [adobe, 237KB ]
The Consolidated DMMO application form is to be used when applying for a permit for a project involving only dredging and/or dispose of dredged material in San Francisco Bay and can be used instead of filling out the individual application forms for each of the Bay regulatory agencies. For projects involving the placement of fill or other work in addition to dredging a regular BCDC permit application should be submitted.

Environmental Work Windows for Maintenance Dredging Projects

As part of the implementation of the LTMS, the agencies initiated state and federal Endangered Species Act consultation with NOAA Fisheries, FWS and DFG for maintenance dredging and disposal projects, covering threatened and endangered species and species of special concern, such as the Pacific herring. These consultations reduced the need for individual consultation for maintenance dredging projects through the establishment of programmatic work windows. Based on the project location and potential species presence, each dredging project has a “work window” each year, during which individual consultations are not needed.

The work windows are those times when dredging and disposal may occur without consultation.

Environmental Work Windows Informal Consultation Packet [PDF 300KB] [DOC 733KB]
Any project proposing to conduct dredging activities outside of the work windows is required to undertake either informal for formal consultation with the appropriate resource agencies (NOAA Fisheries, USFWS, and CDFG). This packet is an overview of when the informal conultation process can be used.
