 Framework for Dredged Material Management
May 2004
Effluent
Water that is discharged from a confined disposal facility during and as a result of
the filling or placement of dredged material.
Emergency
In the context of dredging operations, emergency is defined in 33 CFR Part 335.7
as a "situation which would result in an unacceptable hazard to life or navigation,
a significant loss of property, or an immediate and unforeseen significant
economic hardship if corrective action is not taken within a time period of less
than the normal time needed under standard procedures."
Federal project
Herein, any work or activity of any nature and for any purpose that is to be
performed by or for the Secretary of the Army acting through the Chief of
Engineers pursuant to Congressional authorizations. It does not include work
requested by any other Federal agency on a cost reimbursable basis.
Federal standard
The dredged material disposal alternative or alternatives identified by the U.S.
Army Corps of Engineers that represent the least costly alternatives consistent
with sound engineering practices and meet the environmental standards
established by the 404(b)(1) evaluation process or ocean-dumping criteria (33
CFR 335.7).
Habitat
The specific area or environment in which a particular type of plant or animal
lives. An organism's habitat provides all of the basic requirements for the
maintenance of life. Typical coastal habitats include beaches, marshes, rocky
shores, bottom sediments, mudflats, and the water itself.
Leachate
Water or any other liquid that may contain dissolved (leached) soluble materials,
such as organic salts and mineral salts, derived from a solid material. For
example, rainwater that percolates through a confined disposal facility and picks
up dissolved contaminants is considered leachate.
Level bottom capping
A form of capping in which the contaminated material is placed on the bottom in
a mounded configuration.
Local sponsor
A public entity (e.g., port district) that sponsors Federal navigation projects. The
sponsor seeks to acquire or hold permits and approvals for disposal of dredged
