Tasmanian Gas Pipeline and Zinfra have a number of procedures in place to reduce the environmental impact of their maintenance activities.


We continually reinforce among staff the need to minimise noise and vibration.

Our employees are trained to:

  • Identify noisy activities and adopt improvement techniques.
  • Regularly inspect and maintain plant and equipment to minimise noise and vibration.
  • Develop routes for the delivery of materials and parking of vehicles to minimise noise.
  • Minimise the movement of materials and plant and unnecessary metal-on-metal contact.


During maintenance, dust may be generated which affects visual amenity, vegetation and local air quality. To ensure dust emissions do not adversely affect the surrounding environment and the health, welfare and amenity of people and adjacent land users we:

  • Regularly use water trucks.
  • Keep all vehicles on defined roads and within speed limits.

Spills & Leaks

To avoid spills and leaks we serve machinery at least 100m from any waterway or drainage line. We do not hose into the storm water drains and we use temporary bunding or drip trays when maintaining equipment.

Maintenance teams are equipped with spill response kits to clean up spills should they occur.

Flora & Fauna

We take care not to disturb native fauna when conducting maintenance, repair etc. to the pipeline and easements. TGP takes steps to ensure its presence does not increase weed activity over background levels. This includes the prevalence of existing weeds and the introduction of new weeds.

TGP workers must ensure:

  • No disturbance outside of marked and authorised areas.
  • All vehicles remain on marked roads unless specifically authorised.
  • Vehicle wash-down procedures are in place (if required)

Waste & Litter

Litter is unsightly, can spread disease, attracts fauna and damages vegetation and wildlife. All work crews keep their work area tidy and put rubbish in the bins or skips provided.

Lids are kept on bins and skips to minimise wind-blown litter and access by animals. We keep all vehicles on marked roads unless specifically authorised.

Cultural Heritage

Aboriginal people are the Determined Native Title Holders for the greater part of the onshore section of TGP.

The region contains a rich legacy of rock art and places of cultural significance which TGP employees

When artefacts of cultural significance are discovered — such as archaeological finds, human remains, historical sites, and relics — we take care not to disturb them and alert the appropriate authorities.
