Sellicks Blast 16/11/2018

Update to provide a notification of a blast tomorrow (Friday 16th November) that will be visible to the wider Sellicks community.

The blast location will be in our Eastern quarry development area at the top of the big hill. We are planning to fire mid-morning after 9:30am, as the wind is forecast to swing around to the South-West, meaning that any dust cloud will blow away from Sellicks Beach, up and over the hills to the East.

Community Feedback Survey

To the residents of the Sellicks Community,

At Southern Quarries, we believe that it is through community engagement that we can identify issues that may need to be considered.
As such, as part of our ongoing community engagement strategy, Southern Quarries conducted a survey throughout the month of October 2018 to determine the best form of communication moving forward.

The survey feedback form included a simple list of 5 preferences for community communications and was distributed to 1400 residents of the Sellicks Community.

The breakdown of the first and second preferences of the survey is displayed in the following two graphs.

From the responses, our first direction will be to include people in our community notifications which include blast updates.

We will also organise another site tour as we did in April this year for next year and this could possibly be an annual event.

Kind Regards,

Michael Close

Southern Quarries community update on the construction works currently happening on South Road between the Victory Hotel and the Quarry entrance

The construction works and purple pipe installation is an extension of the recycled water infrastructure South from the Victory Hotel, connecting into the Quarry. Southern Quarries has entered into an agreement with Willunga Basin Water (WBC) to supply 50,000,000 litres of recycled water per year to the quarry for dust suppression activities. The quarry currently relies on mains water for dust suppression activities which include the two water trucks, crushing plant sprays, under-plant sprinklers and stockpile sprinklers located around the site. The recycled water connection will not only increase the amount of water available on a daily basis for dust suppression, but also reduce the reliance on mains ‘drinking’ water for Quarry operations. The recycled water will feed into the 375,000 litre tank that was installed last Summer in January. Recycled water is currently used throughout Aldinga, Willunga and McLaren Vale mainly for irrigation, taken from SA Water’s Christies Beach Wastewater Treatment Plant.

Sellicks Blast 05/11/2018

The blast location will be in the Southern section of the Quarry operations, on the Eastern side of the pit. The current wind and forecast at the time of blasting today (1-2pm) is Westerly, meaning any dust generated will blow over the Hills to the east.

Sellicks Blast 25/10/2018

Update to provide a notification of a blast tomorrow (Thursday 25th October) that will be visible to the wider Sellicks community.

The blast location will be in our Eastern quarry development area at the top of the big hill. The wind forecast tomorrow is for South-Westerly winds at around the time of blasting, meaning that any dust cloud will blow away from Sellicks, up and over the hills to the East.

Sellicks Blast 11/10/2018

Notification of a blast tomorrow (Thursday 11th October) that will be visible to the wider Sellicks community.

The blast location will be in the Southern section of the Quarry operations, on the Eastern side of the pit. The wind forecast tomorrow is for light South-Easterly winds at around the time of blasting. Dust generated from this blast should settle well within the pit and not blow off site.

Sellicks Blast 26/09/2018

The blast location will be in our Eastern quarry development area at the top of the big hill. Some people may have noticed the drill working up there over the past week. The wind forecast tomorrow is for Westerly winds, meaning that any dust cloud will blow away from Sellicks, up and over the hills to the East.

We will be planning to blast a few more times across the top of the hill before summer to minimise the dust generated (there is more moisture in the top surface during winter/spring) and before the South-Easterly winds dominate over the summer period.

Sellicks Blast 02/07/2018 & 06/07/2018

We have two visible blasts coming up. The first will be on Monday (2nd July) and the location will be on top of the hill. You may have noticed the drill positioned on top of the hill over the last week. The forecast for Monday is for North-West winds, which will blow any dust cloud away from Sellicks Beach. The second Blast is planned for Friday (6th July) and will be located at the Southern end of the Quarry. The long range forecast for Friday at this stage is again for North-West winds.

With regards to the Blasts on top of the hill, we have over recent years stopped blasting in this area over the winter period. The reasoning behind this strategy was to minimise the visual impact with the hill ‘greening’ up over winter. When we blast in this area, the brown blasted material is in contrast to the hill, increasing the visual impact. This winter we are going to fire a few more blasts across the top, as with more moisture in the top surface with winter rains, the dust generated from the blast is reduced. The predominate wind direction over this period is also from the West, meaning any dust generated will blow away from Sellicks Beach residents. We hope the effort to minimise the dust impacts, outweighs the increased visual impact of this area. As the blasted rock is removed from each blast, we place soil at the front which can then be seeded. The cover of grass helps reduce the visual impact and also provides a cover of vegetation over the summer.

People may have also noticed some areas around the quarry starting to ‘green’ up as we move well into winter. To date we have spread around 3 tonnes of Rye Corn grass seed, with a further 5 tonnes planned. As we try to complete each season, disturbed areas are covered with top soil / sub soil. These areas are then hand seeded with Rye Corn. The Rye corn grass provides a good initial cover and when it dries out over summer maintains that cover, dropping seed for re-growth the following year. The recent area’s that have been prepared for seeding are across the top of the big hill and Western Screening mound. We still have more work to complete on the lower level of the Screening mound before we can seed. Additional to the grass seed, we are about to plant 2,500 trees across the site. We don’t have any new areas to plant trees this year, with these 2,500 trees replacing previously planted trees that have not survived and filling in gaps between existing trees. On average we plant around 2,000 trees per year.

If anyone has questions or concerns please let us know via email communityfeedback@southernquarries.com.au

Sellicks Blast 17/04/2018

Notification of a blast today that will be conducted on top of the hill and visible to the community. Weather conditions today are favourable with light winds forecasted, meaning the dust cloud should settle well within the pit.

Sellicks Blast 24/02/2018

The blast location will be in our Eastern Quarry development area at the top just behind the big hill, which is approximately 750m East of South Road. The wind forecast tomorrow is for a light North Westerly wind after lunch, meaning that any dust cloud will blow away from Sellicks, up and over the hills to the East.

For each blast conducted on site, we setup a monitor to record blast vibration and noise. The monitor station is located near South Road. All Quarries are required to adhere to Australian Standards limits for ground vibration and air blast overpressure (noise). Generally our readings are well below the limits and for some blasts not even registering at the monitor station.

Sellicks Blast 20/02/2018

We are planning to blast tomorrow afternoon at the Quarry.

We have been monitoring the weather and tomorrow does look ok to blast, based on the winds. BOM Forecast is “Winds east to southeasterly 25 to 35 km/h tending east to northeasterly 20 to 30 km/h in the morning then tending east to southeasterly 15 to 25 km/h in the evening”. I have also attached the Windfinder forecast FYI. Both indicate the wind will drop tomorrow and swing NE. We generally are ready to fire early afternoon, so we are expecting light to moderate NE winds at this time and the dust cloud produced should blow south of Sellicks Beach.

Kind Regards,

Michael Close
