Cleaning out of dams adjacent to the pipeline

As a landholder or contractor, you must contact SEA Gas prior to enlarging or cleaning out of any dams that are adjacent to the pipeline easement and especially where that cleaning or enlarging work is towards the easement.

Core Sampling

When taking core samples from any site near or adjacent to the SEA Gas pipeline easement, you must contact us prior to the commencement of the work. In most rural vacant land and cropping paddocks the pipeline is buried at less than a metre in depth. As core sampling can occur at this depth or deeper, it is a requirement that you contact us to locate the pipeline.

Planting on the pipeline easement

SEA Gas is required by law to maintain line of sight between the marker signs. This means that no trees are to be planted on the pipeline easement. Smaller shrubs may be permitted but only after consultation with the SEA Gas.

Crossing the SEA Gas pipeline easement with heavy vehicles

If vehicles are required to cross the pipeline easement frequently then several factors have to be considered, such as:

  • Axle loading
  • Terrain
  • Depth of cover
  • Frequency of traffic movement
  • Weather conditions.

An example of this would be harvesting of pine or gum plantations. Contact SEA Gas to discuss appropriate protection measures prior to the commencement of vehicle activity.

Pipeline Marker Signs

The pipeline marker signs are installed as a guide only and may not be the actual location of the pipeline buried below. In order to ensure that you carry out your work safely always contact Dial Before You Dig or SEA Gas direct.marker-sign-2

Pipeline marker signs are a reminder that there is a high pressure gas transmission pipeline buried in the vicinity. Note that some signs may show “off set” markers. Signage is usually placed within the easement and will not always be directly on top of the pipeline.

To ensure line of sight and indicate change in direction of the pipeline, signage must not be removed.

Depth of Cover

Cover varies throughout the length of the pipeline. Regardless of whether you believe you know how deep the pipe may be buried you are still required to contact SEA Gas and the Dial Before You Dig service to ensure the pipe is located accurately and so that your work can be carried out safely.

Easement Widths

Note that the width of the easement may vary along the length of the pipeline and may be as wide as 25 metres.
