Hello Registered Sellicks Community Members,
Email to provide further updates and progress of current initiatives to further reduce dust generation from Sellicks Hill Quarry:
- Installation of a 500 tonne storage bin for the Secondary Sand Open Stockpile – this project has encountered additional delays due to engineering drafting for the structural design and painting not being completed on schedule. Revised completion is now the 31st December 2019 to allow for full construction and commissioning of the storage bin. A 150 tonne crane will be onsite next week to complete the final lift’s and stand the structure in place. We are continuing to divert the sand stockpile to another section of the plant and apply additional dust mitigation strategies until the storage bin is completed.
- Enclosing the Primary Dump Chute and Crusher – this project is progressing well, but due to the size and complexity of the shed enclosure, the original due date of 31st January 2020 is becoming a concern to complete construction. Concrete foundations are planned to be installed mid-December 2019, followed by a construction program of 5-6 weeks for the enclosure. The construction program cannot commence until approximately 14 days after the concrete foundation has been completed. Southern Quarries has therefore sort approval for an extension to the completion date of the Primary Enclosure to 1st March 2020, which the EPA has approved. The primary crusher will not be in operation until the shed enclosure has be completed.
- Both of these delays and new completion dates have been updated and included in the site Dust Management Plan (DMP) which has also been recently approved by the EPA.
- Recycled Water – the connection for recycled water is now completed and in use at the site through the water trucks for haul road and stockpile dust suppression. To alleviate any concerns with the use of recycled water and spraying through the water truck, a secondary chlorine dosage system was installed to further treat the water and remove 99.9% of any residual bacteria contained in the recycled water. The agreement with Willunga Basin Water to supply 50,000,000 litres of recycled water per year will not only increase the amount of water available on a daily basis for dust suppression (particularly over summer), 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 in January 2018.
