Planned liquid discharges

The liquids which may be discharged into the environment  include:

Impacts upon environmental receptors

Impacts have been assessed for receptors in the:

  • Physical environment (water quality and sediment quality)
  • Biological environment (fish, marine mammals and other underwater species, birds and marine plants)

There are no assessed negative impacts on socio-economic environment receptors from planned liquid discharges.

As discharges will rapidly dilute and disperse in the open ocean environment, modelling studies indicate impacts to water quality are likely to be highly localised around the point of discharge. Because of the deep ocean environment and strong currents, there will be no expected impacts to sediment on the sea floor.

Therefore all impacts and risks to receptors have been assessed as being as low as reasonably possible, and therefore of an acceptable level.
