Boral Quarries Coldstream
531 Maroondah Highway
Coldstream VIC 3770
The Boral Coldstream Quarry is located on the northern face of Bald Hill, positioned between the outer Melbourne suburb of Lilydale and township of Coldstream.
With earliest operations commencing in 1902, the quarry has provided a source of hard rock aggregate used throughout Melbourne's east, south-east and CBD.
Coldstream's toscanite rock resource is mainly used for crushed and exposed concrete products.
The Boral Coldstream Quarry was established in 1900’s as Black Quarry. Following various expansions and ownership changes Boral acquired the quarry in the 1960’s.
The quarry is located off the Maroondah Hwy just outside the township of Coldstream.
Resource from the quarry is used in predominantly crushed concrete and exposed concrete aggregates products. The site supplies approximately 100,000 tonnes per annum of total product to internal and external customers.
The quarry site occupies over 90 hectares of land.
Planning and Approvals
Boral Coldstream Stockpile Relocation Project
Presently we are looking at improving the use of our operations at the Coldstream Quarry, especially the location of the crushing plant and ‘sales’ areas.
We are in the process of applying for a planning permit through Yarra Ranges Council for the relocation of our stockpiles (large piles of aggregate ready for sale), weighbridge and offices into a section of land located north of the quarry.
The current location of our stockpiles presents traffic management challenges as both the stockpiles and weighbridge are located within the area being quarried. This is an unusual arrangement as it is typical practice for haul trucks to bring products from the quarry to the stockpile area for sale.
We are therefore in the process of applying for a planning permit through Yarra Ranges Council for the relocation of our stockpiles, weighbridge and offices into a section of land located north of the quarry pit. This area already contains a weighbridge and office from a previous business, sufficient space for materials to be stockpiled, and adequate space for heavy vehicle traffic. By locating the stockpiles away from the extraction zone, we will minimise the risk of intermingling heavy vehicles and improve safety for site operators and truck drivers.
New sales hours
As part of the application for the relocation of our stockpiles, weighbridge and offices, we are also seeking to extend sales activities to 24 hours per day. There will not be any changes to operating hours for production purposes, including crushing, blasting and general operations.
It is expected that the modification of sales hours will allow for truck movements to be more spread out across the day, reducing the number of concentrated movements along the Maroondah and Warburton highways during peak traffic periods.
It is anticipated these changes will have minimal effect on the community. We are currently investigating various ways to enhance the visual amenity of the site as we understand and appreciate the picturesque environment in which the quarry operates. Traffic, dust, noise and vibration management plans have been undertaken to ensure there is little disturbance to our neighbours.
General Operating Approvals
The quarry's main approval is Extractive Industry Work Authority 96 (WA96), issued under the Mineral Resources (Sustainable Development) Act 1990. This allows the operation of extractive activities at the site for the life of the resource.
Planning permission to operate the quarry is from existing use rights which reflect the long term use of this land as a quarry, dating back to the first operators in the 1900’s. Expansion of the quarry would require further approvals from the Council.
The quarry also has an Environmental Licence MW802 issued by the Environmental Protection Authority (EPA) Victoria.
The Boral Coldstream supplies building and construction materials to the eastern region of metropolitan Melbourne.
A number of activities are undertaken at site including
- Stripping- the removal of 'overburden' (soil, sub-soil and other material which sits on top of the hard rock resource);
- Drilling and blasting- use of controlled implosions to expose the hard rock for processing;
- Loading and hauling- transfer of rock to other sites;
- Crushing and screening- during peak sales periods a mobile crushing plant is located at the quarry to produce the various grades of aggregate, otherwise material is sent to other Boral quarries for processing; and
- Stockpiling, sales and transportation- storage an movement of products to market.
