As professionals working in the development, permitting and implementation of coastal projects, we are familiar with the complications that contaminated sediment can cause for projects. What are the options when a project requires the disposal of highly contaminated sediments know as Unacceptably Contaminated Sediments (UCSs)?

Confined Aquatic Disposal (CAD) Cells have become one method in New England for disposal of sediment deemed unsuitable for unconfined open water placement. Coastal CAD Cells are depressions (either natural or man-made) in the seafloor where contaminated dredged material can be placed. When the cell becomes full, a cap of clean sand ‘closes’ the cell to further isolate the surrounding marine biota from the disposed dredged material. There are CAD cells along the coastline of New England that are in use now, serving as cost-effective disposal sites for projects with highly contaminated sediment.

Final Agenda – Ocean and Coastal Resources Webinar – CAD Cells

This EBC Ocean and Coastal Resources webinar will provide a background on CAD cells, including: what is a CAD cell, how a location is selected for construction, how and by whom it is constructed, what permissions and authorizations are required for disposal, and what types of materials are authorized to be placed in a CAD cell. Speakers for this webinar will include government regulatory authorities, marine contractors, and consultants. Collectively, they will provide important information and perspectives on the eligibility of material to be placed in a CAD cell, environmental and biological concerns of their use, long-term sampling and monitoring programs, and maintenance challenges of CAD cells.

Don’t miss this EBC program if you want to learn more about how a CAD cell could play a role in your future project.

General Continuing Education Certificates are awarded by the EBC for this program (2.0 training contact hours). Certificates are automatically provided via email link for registered attendees at the conclusion of the webinar.
