Basically, CEPA provides an absolute prohibition on disposal from ships, aircraft or platform or other structures at sea. The CEPA permitting program allows us to issue permits for a limited number of low-risk materials that are found in schedule 5 of CEPA, the largest of which is dredged material that is cleared from shipping channels and harbours, in order to keep our ports and harbours open.
In order to get a permit, you have to go through a strict assessment of the material, the disposal site and the operations around the disposal at sea. Those provisions can be found in schedule 6 of the act.
