Framework for Dredged Material Management
APPENDIX A: GLOSSARY
Definitions of terms as they are used in this document are given below.
The geochemical environment in which dredged material is submerged under
water and remains water saturated after disposal is completed.
Bodies of water, including wetlands, which serve as the habitat for interrelated
and interacting communities and populations of plants and animals.
Belt of the seas measured from the line of ordinary low water along that portion
of the coast that is in direct contact with the open sea and the line marking the
seaward limit of inland waters (see Figure 1-1 in the main text).
Placement or use of dredged material for some productive purpose. Beneficial
uses may involve either the dredged material or the placement site as the integral
component of the beneficial use.
The accumulation of contaminants in the tissues of organisms through any route,
including respiration, ingestion, or direct contact with contaminated water,
sediment, or dredged material.
The controlled, accurate placement of contaminated material at an open-water
site, followed by a covering or cap of clean isolating material.
Includes coastal waters and the adjacent shorelands designated by a State as being
included within its approved coastal zone management program. The coastal zone
may include open waters, estuaries, bays, inlets, lagoons, marshes, swamps,
mangroves, beaches, dunes, bluffs, and coastal uplands. Coastal-zone uses can
include housing, recreation, wildlife habitat, resource extraction, fishing,
aquaculture, transportation, energy generation, commercial development, and
Placement of dredged material within diked nearshore or upland confined disposal
facilities (CDFs) that enclose the disposal area above any adjacent water surface,
