The aim is to minimise seabed disposal and seek alternative, beneficial use by conducting a Best Practicable Environmental Option ( BPEO) assessment and considering practicable alternative options before granting a licence. Sea disposal sites are selected based on a number of criteria including their location in relation to amenities and other uses of the sea in the area, economic and operational feasibility and physical, chemical and biological characteristics. A further 50 sites are either closed (not having been used for at least 10 years) or disused (not having been used for at least five years). There are 66 open sites routinely used for disposal. This activity is essential to maintain navigation in ports and harbours as well as for the development of new port facilities. Only the disposal of dredged material from ports, harbours and marinas is presently allowed. Since the 1980s disposal at sea of radioactive wastes (stopped in 1982), industrial wastes (1992), colliery mine-stone (1995) and sewage sludge (1998) has been progressively reduced, and is now prohibited.
