Dredge permits are issued pursuant to Section 10 of the Rivers and Harbors Act of 1899, and Section 404 of the Clean Water Act, among several others.

The Dredged Material Management Office (DMMO) is an interagency group made up of representatives from the San Francisco District US Army Corps of Engineers (COE), the U.S. Environmental Protection Agency (EPA), the San Francisco Bay Conservation and Development Commission (BCDC), San Francisco Bay Regional Water Quality Control Board (RWQCB), and the State Lands Commission (SLC).  Also participating are the National Marine Fisheries Service, the US Fish and Wildlife Service, and the California Department of Fish and Game.  These wildlife agencies provide advice and expertise to the DMMO process.

The purpose of the DMMO is to cooperatively review sediment quality sampling plans, analyze the results of sediment quality sampling and make suitability determinations for sediment proposed for dredging and disposal in San Francisco Bay.  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.

Applicants using the DMMO process fill out one application form, which combines the informational requests of all the DMMO agencies.   The agencies jointly review applications, sediment sampling plans and test results at regular (usually bi-weekly) meetings before processing applications or authorizing dredge episodes pursuant to each agency’s respective rules and regulations.
