Marine Environmental Management

Cockburn Cement dredges shellsand from its approved Long term Stage 2 dredge area on West Success Bank in Owen Anchorage. Environmental approal for the Long Term Stage 2 area is provided under Ministerial Statement 599 until July 2030. Various management plans within our overall Environmental Management Plan (EMP) address the potential impacts of dredging to the surrounding marine and coastal environment, and include:

  • Monitoring changes in wave climate (i.e. wave height and direction) due to the increased water depth created by dredging.
  • Determining the potential effects of changes in wave climate on coastal structures (eg groynes, jetties), shipping and navigation and the seabed and shoreline.
  • Monitoring sensitive marine habitats (ie seagrass meadow health) to ensure there is no loss due to dredging related turbidity.

All activities carried out in the EMP are reported each year in our environmental compliance report which is submitted to the Office of the Environmental Protection Authority (OEPA) as a condition of the Ministerial approval.
