Guidance for the Development of Action Lists and Action Levels for Dredged Material 2009 Edition

Product Description

Following the decision, in 2002, to prepare technical guidance on the development of an Action List under the Generic Guidelines that would assist Contracting Parties in developing their own National Action Lists and address the potential effects on human health and the marine environment, the Scientific Groups under the London Convention and Protocol developed the Guidance for the Development of Action Lists and Action Levels for Dredged Material in working and correspondence groups, initially led by the United States and subsequently by Canada. In May 2008, the Scientific Groups completed their work and the governing bodies adopted the Guidance in October 2008.

The guidance assists regulators and policy makers on the selection of Action Lists and the development of Action Levels for dredged material proposed for disposal at sea. An Action List is a set of chemicals of concern, biological responses of concern, or other characteristics that can be used for screening dredged material for their potential effects on human health and on the marine environment. Action Levels establish thresholds that provide decision points that determine whether sediments can or cannot be disposed of at sea.

While the Guidance is designed to assist with implementation of requirements under the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter, 1972 and its 1996 Protocol, the guidance provided is general and could be applied to the assessment of dredged material under other instruments. The guidance does not, however, cover the assessment of other wastes or other matter allowed under the London Convention and Protocol.
