The project extends environmental management strategies and places limits and controls on output.

The area of the site to be quarried is located in the lower part of the land holdings and will minimise visibility and other environmental impacts.

A site based Environmental Management Plan has been established along with conditions of approval and this includes extensive flora offsets which include:

  • Early identification of speciesEnvironment - planting-tree
  • The establishment of over 50,000 new trees over the life of the quarry
  • Three to five trees established for every tree removed
  • Greatly enhanced wild life corridors and connectivity
  • Provides for detailed and on-going management requirements
  • Will incorporate Koala habitat tree offsets in accordance with SPRP

The protection, by law, of more than 72% of land holdings, free from  quarrying and creating one of the regions single largest  protected habitats in the region.

This will greatly increase the city’s habitat holdings.

This establishes enormous potential for Koala population expansion.

Stormwater and Management:

A water management strategy has been included in the Environmental Management Plan and best water management practices will be implemented to protect downstream water quality including integrated water and erosion control devices and water treatment systems.

Water runoff at the quarry is also regularly tested for measures such as pH and suspended solids to ensure any water discharged meets requirements set by the Department of Environment and Resource Management..Pond

It ensures the diversion of clean water and establishes settlement ponds for containment of clean water from disturbed areas.

As well, a rigid program of regular monitoring and reporting of water management will be on-going over the life of the project.

Noise and Dust:

In 2008, an EPA and Queensland Health study found that the quarry dust emissions in the Mount Cotton Quarry area were well within the prescribed guidelines and therefore posed no risk to residents or Barro Group employees.

The Dust Impact Assessment prepared for this project by MWA Environmental also determined that with the appropriate dust controls and management measures, surrounding residences would not be exposed to dust above the levels prescribed in the Queensland Environmental Protection (Air) Policy 2008.

Barro 8[1]Barro Group has ensured that the location, layout and staging of this proposed development have to a large extent been predicated by consideration of environmental issues including dust.

The project will comply with Department of Environment Heritage Protection  noise and dust criteria.

The new plant will be state of the art 21 century technologies and will ensure enclosure or partial enclosure of plant facilities.

The site’s acoustic attenuation of natural topography has also played a key role in the planning and design.

As well the project will utilise covers over all trucks.

Visual Amenity:

The extension area is located in the lower part of the site and is surrounded by ridge lines on three sides, which means minimal views from surrounding vantage points.

Where views are possible they are largely obstructed by topography and vegetation and mature well established vegetation exists in buffers.


Previous traffic studies have found the anticipated future vehicle movements at the quarry will continue to be readily absorbed by the traffic flow at the site entrance and on Mount Cotton Road.  Additionally, no new roads or site entrances will be required under this project, however an upgrade to the existing entrance will be undertaken to improve safety.

Over the past 30 years the number of trucks transporting material from Mount Cotton Quarry has fluctuated in line with market demand.

This fluctuation is standard to the industry and will continue into the future.  Trucks are essential for transporting extractive resources to communities across South East Queensland and with demand continuing to grow and the cost of living rising, it’s important a source of product can be located close by.  The Mount Cotton Quarry is situated near the market it supplies, which means transport costs, along with the overall cost of construction, can be minimised.

Under this project, the quarry will continue to operate within similar daylight hours as the existing quarry.  The current site access, which has been previously upgraded and designed to accommodate the existing operations, will, with a additional upgrade,continue to operate safely and efficiently.
