We're protecting the environment during construction

EPBC planning approvals

Stage 2 of the O’Herns Road Upgrade was referred for assessment under the Environment Protection and Biodiversity Conservation Action 1999 (EPBC Act). The project was deemed a Controlled Action under the Act, as parts of the project contain habitat for federally listed threatened species including the Golden Sun Moth and Growling Grass Frog.

The Preliminary Documentation for the EPBC approval was made available for public comment between 9 October 2018 and 22 October 2018, during which no comments were received.

EPBC approval was granted in June 2019, and the necessary conditions required to enable the approval were met in early July 2019.

What is the EPBC Act?

The EPBC Act enables the Australian Government to join with the states and territories in providing a national scheme of environment and heritage protection and biodiversity conservation. The EPBC Act focuses Australian Government interests on the protection of matters of national environmental significance, with the states and territories having responsibility for matters of state and local significance.

Growling Grass Frog Conservation Management Plan

Our environmental assessments have identified a movement corridor for the federally listed Growling Grass Frog. A Growling Grass Frog Conservation Management Plan has been developed to protect Growling Grass Frog populations and describes what protocols will be in place to ensure their habitat and connectivity is maintained along Edgars Creek during and after the O’Herns Road Stage 2 Upgrade.

Protection of flora and fauna

We’re protecting flora and fauna in the project area through environmentally sensitive design and construction methods. We’ll do this by:

  • creating dedicated areas of habitat  in compliance with our environmental approvals
  • protecting trees and other sensitive vegetation with ‘no go zones'
  • having a dedicated environmental specialist to oversee the protection of any sensitive vegetation.

Managing air quality

Construction is happening near residential properties, businesses and other public areas, so it’s important that we manage air quality in the area. We’ll do this by:

  • watering areas where earthworks are occurring
  • having additional water carts on standby during hot and windy weather
  • covering truck loads when travelling on public roads
  • planning topsoil stripping and grading on days when wind conditions are less likely to carry dust
  • minimising the time between stripping topsoil and commencing excavation
  • reducing speed limits or using crushed rock to pave long-term haulage routes
  • hydro-seeding stockpiles of topsoil and installing temporary wind fencing
  • dust monitoring in areas adjacent to high activity construction sites and residential properties.
