                                          (1) of sufficient size for the projected volume of dredged

                                              purpose of material storage and dewatering.

                                          the dredge management plan specifies that material is
                                          placed at a dredged material disposal site only if it is
                                          demonstrated that it is not feasible to:
                                          (1) dispose of the material above the high water mark, if
                                               the material is from maintenance works for an
                                               existing artificial waterway for which at-sea disposal
                                               was previously approved, or
                                          (2) keep the dredged material within the active sediment
                                               transport system for the locality, or
                                          (3) use the material for beach nourishment or another
                                               beneficial purpose.

                                          management plan has the capacity to hold and retain the
                                          material within its boundaries during construction and
                                          operation of the development.
                                          Editor’s note: The use of dredged material for a beneficial
                                          purpose could include development of port or other marine
                                          facilities, use for construction or industrial purposes, or use to
                                          create or modify land or waters for an approved environmental
                                          outcome (such as creation of a bird roosting site). Further
