CEDA:
• is a vital network for the exchange of knowledge and experiences in dredging
• is a centre for communication and training about environmental aspects of dredging
• is a platform for promotion of dredging as a tool for sustainable development
www.dredging.org
Aims of CEC
• To promote the education and instruction of its members and others in those fields concerned with dredging and dredging-related activities.
• To generate and disseminate quality information on dredging and associated matters
• To develop or contribute to the development of guidelines relating to good practice.
• To stimulate (and join) the initiation of and/or support research relevant to dredging activities
• To be pro-active in providing expertise in relevant policy making activities
• To develop close links with NGOs
www.dredging.org
Activities
• Workshops/seminars• Taskgroups• Participating in LC, OSPAR, Danube Commission• WFD Navigation Task Group “• Positioning papers• Own guides• Other guides• Environmental Day on Wodcon• Best paper award

Environmental Aspects of Dredging

Outline
• Motivation: Why the Guides?• Why the update?• What can you and what should you not expect • Structure and content• A more detailed look at one chapter• Practical details
www.dredging.org
Motivation
No one denies anymore that
we all have to take a responsible attitude towards the way we live and we behave in our environment.
www.dredging.org
Motivation (cont’d)
No one denies either that
dredging and relocating dredged material per definition have an environmental impact.
But as the WODA Environmental Policy (1998) states:… dredging projects can be conceived, permitted and implemented in a cost-effective and timely manner while meeting environmental goals and specific regulatory requirements.
www.dredging.org
Motivation (cont’d)
methodologies and guidelines needed
How to achieve this?We in the industry should be able • to predict and assess the effects of a planned
dredging activity in a scientifically sound and reliable and
• to introduce appropriate control measures
This is what the book will provide!
www.dredging.org
Motivation (cont’d)
Need for information recognised more than 10 years ago
IADC/CEDA effort: The Guides (1996-2001)
www.dredging.org
Use and value of the Guides

Use and value: Training

Guides Book
• Revision of original material• Recent advances in knowledge
and technology• New structure
www.dredging.org
What can you expect from the book?
It is an aid to engineers, government agencies and port authorities, civil engineering consultants and contractors involved in planning and designing dredging works.
• A balanced view• Comprehensive information + sources for further research• It leads the reader through a state-of-the art environmental
evaluation process• It DOES FAVOUR particular approaches • It DOES NOT FAVOUR neither the promoter nor the opponent of
dredging works
www.dredging.org
What should you NOT expect from the book?
It DOES NOT prescribe specific environmental controls.
www.dredging.org
The Book in practice: “Health warning”
Take special care in particular when setting environmental controls.
Use the “framework”, consider local particularities and apply it to the local conditions.
= framework + case studies
www.dredging.org
The golden rule of setting environmental controls:
Promoter/Authorityshould set local limits and preferences according to local environmental conditions and sensitivities
Contractor/operatorshould be allowed to operate in any reasonable manner provided environmental goals to be met
