Erosion and Sediment Control Project

One of the key risks identified when disturbing land, for example during excavation and construction activities, is erosion by water and run-off of the resulting sediment-laden water. Santos has implemented a series of standardised erosion and sediment control (ESC) plans in Queensland that target recurring activities that disturb land, for example well pad, pipeline and access track construction.

ESC management plans assess the risks associated with a proposed activity and consider:

  • potential soil loss
  • disturbance size and type
  • proximity of location to any water (ground or surface)
  • soil, vegetation and topographic features present at the proposed disturbance and surrounds

This risk assessment process determines whether the site and proposed disturbance would constitute a very low, low, medium or high risk. The appropriate standard procedures, that contain ESC measures can be implemented and are understood by all teams involved, are then implemented .This ensures that consistent management techniques are used across activities throughout the life of a site. For high risk sites a site-specific ESC Management plan is required.
