Surplus excavated material

Excavated material becomes surplus if:

• Its irrecoverable physical, chemical or biochemical quality prevents it from being used in a development;
• There is more material than required for the development; or
• The requirement for a type of material is too far away from the excavation point to make its use practicable.

Sustainable placement is the on-site placement for disposal of surplus excavated material to avoid causing environmental effects (e.g. transport) that would otherwise be associated with the off-site disposal of that material. ‘On-site’ in this context means within the land required for the purposes of the development and ‘off-site’ means external land
(or landfill site) which is not specifically required for the purposes of the development.

A sustainable placement area is an area used for sustainable placement.
