Miners Rest Rehabilitation Project
Boral has been present in the Ballarat region for many years, not only as a retailer of building materials, but as the operator of several local quarries, a major asphalt facility and a concrete plant. One of these quarries, located near Miners Rest, closed in 1999.
The Miners Rest Quarry on Cummins Road operated for about 30 years under lease from private owners. Approximately four years ago the former quarry site was sold to a new landowner.
Under the lease terms and the Mineral Resources (Sustainable Development) Act 1990 Boral is required to rehabilitate the site.
Rehabilitation will include re-shaping some of the quarry faces, removing the surrounding earth wall screens, and general restoration.
The major works to be undertaken as part of the rehabilitation of the site include the relocation of overburden visual earth barriers (bunds) to open up views from within the site. The majority of the materials making up the overburden bunds will be relocated, shaped and contoured to match the natural landform.
Other works include cutting back and shaping the previous quarry benches into visually appealing landforms.
Works are planned to commence in September 2016. It is anticipated that all major earth works will be completed in a 12 month period. Revegetation of the site will rely on seasonal factors, with an anticipated completion within 24 months.
In order to rehabilitate the site to the above standards, some blasting and heavy earth moving activity will be required. The blast design and implementation will be performed by Boral’s experienced drill and blast team. They will ensure that current environmental limits for noise and vibration are met. As the local community has not experienced blasting at the site for over 15 years, Boral will notify all residences within 500 metres of the site boundary well in advance of any blasting event(s).
Significant weed infestation across the site has been noted. This includes declared noxious species Gorse, African Boxthorn, English Broom and Paterson’s Curse.
To control and eradicate these weeds from the site a weed contractor will be engaged to spray all weeds with suitable and approved chemical sprays. The poisoned weeds will be collected and transported to a suitable location, then buried to depths of up to 3-4 metres.
Follow-up spraying with suitable herbicides will be performed where and when necessary on any remaining weeds.
All reshaped and recreated surface areas with a relatively flat slope will be sown with pasture grasses. All available top soil from the bunds will be used to provide a suitable product for the grasses. Other mulch type products may be imported and used to supplement the available top soils.
Recreated slopes will have small shrubs and trees planted to stabilise the ground surfaces. Short lived pasture grasses may also be sown to stabilise the surface prior the shrubs taking hold.
Dust and noise management
There are a number of controls available for dust mitigation if it presents an issue for the site and neighbouring properties.
If needed, the following control measures will be implemented:
- Use of the water truck to provide additional applications of water to all accessible areas of the quarry including internal roadways
- Minimise amount of travel around quarry site
- Increase rate of watering regimes to areas scheduled for disturbance
The site will adhere to approved operating hours at all times. The operating hours onsite are 6am - 6pm on weekdays and 6am - 12pm on Saturdays. No operations are undertaken on Sundays or public holidays with the exception of plant maintenance.
All equipment and machinery selected to operate on site will have appropriate noise reduction devices fitted and be regularly maintained in good working order.
Access tracks and haul roads will be maintained to prevent corrugation that contributes to truck noise.
