Return of clean sediment on site

Return of clean sediment on site

Type of treatment: Final disposal

Description:

Return on the beaches of sediments (sand and pebbles) to limit the erosion.


Waste:

Clean to lightly polluted sand and pebbles.


Situation/Possibilities in the country:

N/ A


Interest:
·         Limits the coastal erosion.
·         Diminishes the volume of waste to dispose of.

Entry criteria:

Sediment must be clean to be returned on the beaches (however, sediments will continue to be cleaned in exposed areas by the action of the waves, see “surfwashing”).
There are no general rules for the return of the sediments on site. Each situation will be studied on a case by case basis by the National Authorities. Example of ERIKA oil spill in France: the threshold was set at 2,500ppm for the cleaned sediments.


Operational constraints:

Requires personnel, transport equipment and earth moving equipment.


Impacts:

None for clean to very lightly oiled sediments.


Legal constraints:

None.


Efficiency:

Complete.


Cost:
CAPEX: no specific equipment required.

OPEX: hire existing equipments and personnel.
