Application and approval process | Quarrying first began on this site in 1882 with Boral taking over the operation in 1994. There is currently an approved Mine Operations Plan (MOP) for the Linwood Quarry which was approved by DEM in October 2008. On 6 December 2018, Boral submitted an application for a mining lease for the eastern expansion area and supported by a mining proposal to the Department for Energy and Mining (DEM). The application was made available for public comment on 16 May 2019, with comments to be submitted by 27 June 2019. 11 submissions were received from members of the public. The Department for Energy and Mining reviewed all submissions made by members of the public along with technical input from a number of South Australian government Departments including, but not limited to, the Environment Protection Authority, Department for Environment and Water, and the Department for Planning, Transport and Infrastructure. DEM determined that additional information was required to enable assessment of the application, and a request for a response document was prepared. The applicant was required to formally respond to all matters and requests for further information raised by the public and the South Australian Government. The applicant submitted their response document on 3 June 2020. This response document, along with the public submissions, the government’s request for response document has been published on this website (see “Current documents and reports” below). and the original Mining Proposal can be found on the Boral Website. On 14 May 2021 the mining lease for extractive minerals, EML 6525, was granted for a term of 21 years. The current operational program for the quarry must be revised by Boral and approved by DEM prior to commencement of mining operations in the eastern expansion area. The currently approved Mine Operations Plan (MOP) authorises operations on the remainder of the Linwood Quarry mining tenements. |

Public submissions received Response documents The request for response letter includes a consolidated list of matters raised by relevant South Australian Government departments, and outlines further information required by the applicant. Combined Mine Operations Plan (MOP) and Program for environment protection and rehabilitation (PEPR) The current operational program for the quarry must be revised by Boral and approved by DEM prior to commencement of mining operations. As the operation includes private mines which require a MOP, and mining leases which require a PEPR, Boral are currently preparing a single combined MOP/PEPR for the operations to address the legislative requirements for all tenements. Following submission and government assessment, if the MOP/PEPR is approved it will be made available on this web page. Current Mine Operations Plan A Mine Operations Plan (MOP) for the Linwood Quarry was approved by DEM in October 2008. The MOP contains a description of the existing environment, description of mining operations, and a set of environmental objectives and measurement criteria which must be achieved for the site. Mine Operations Plan (MOP) 2008 - please refer to the Boral Website. In December 2016, DEM endorsed a minor variation to the Linwood Quarry operations after a detailed risk assessment process was undertaken on a proposal to extend the southern face of the quarry approximately 25 metres to the south. The top two benches of the quarry have now been completed to the southern-most limits of this endorsement. Risk Assessment documentation - please refer to the Boral Website. The EPA licenses activities of environmental significance and monitors water, air and noise pollution. Linwood Quarry's current operations, are subject to this requirement for EPA authorisation.
