Within the framework of the London Convention 1972, Contracting Parties have recognized that dredged material, due to its characteristics, can be managed separately from waste materials. In 1986, the Tenth Consultative Meeting adopted "Guidelines for the Application of the Annexes to the Disposal of Dredged Material" (resolution LDC.23(10)). It was agreed that the guidelines should be kept under regular review to take into account developments in dredging technology and improved understanding of the environmental consequences of disposal at sea.
