Understanding dredging

Last call to complete CEDA questionnaire for developers and users of turbidity limits

The questionnaire closes on 30 September 2016.

Increasing environmental scrutiny for dredging projects has introduced threshold limits for turbidity generating activities (incl. dredging and dredged sediment placement). The setup, basis, monitoring and management of ‘turbidity limits’ is widespread, but very disperse.

Therefore, the Environment Commission of CEDA developed a questionnaire to record, inform guidance and best practice in setting and working with turbidity limits.

CEDA members and other stakeholders, whether regulator, project owner, contractor, or consultant, are invited to complete the questionnaire and share their insight relating the challenges faced around turbidity limits.

The responses will be used to develop an information paper which all respondents will have access to.

The questionnaire consists of four parts:  

  • Part 1 – establishes project type and conditions
  • Part 2 – investigates how turbidity limits were set for the project
  • Part 3 – deals with monitoring effort and set up for the project
  • Part 4 – covers responses and exceedance procedures/efforts

Please fill in the questionnaire online by clicking the link http://goo.gl/forms/UaeHBF9cfK or download the hard copy from here and send the completed and scanned pages to the attention Anna Csiti at ceda@dredging.org.

Please only cover one project per questionnaire when responding.

IMPORTANT: The project information will be treated confidential and will only be used in a statistical manner for the information paper without disclosure of the source.
