Our significant environmental aspects

Any activity that may have a major impact on the environment is classified as a 'significant environmental aspect'.

Energex's activities (environmental aspects) and their associated impacts can be broadly categorised as national, regional and local.

Within these categorisations the following types of matters would exist:


  • Infrastructure proposed in, traversing or adjacent to Ramsar wetlands or World Heritage areas
  • Submarine cables in marine mammal habitat
  • Infrastructure works that affect federally listed threatened species (flora and fauna), migratory species and ecological communities
  • Interstate transportation of regulated waste


  • Bushfire
  • Remnant ecosystems mapped by the state
  • Infrastructure works that affect state listed threatened species (flora and fauna) and essential habitat


  • Noise from operating and maintaining existing infrastructure and construction activities
  • Air quality from local generation
  • Oil spillage

These issues vary in significance from project to project and site to site depending on individual circumstances.

To accommodate the continual assessment of these variables, we have implemented an environmental management system (EMS), which regulates and monitors our environmental objectives.

In addition, environmental impact assessments are published for major projects, such as:

  • Community infrastructure designation and impact assessable development applications - under the Sustainable Planning Act 2008.
  • Significant Projects - under the State Development and Public Works Organisation Act 1971 - that address specific significant environmental aspects of individual projects.
