If an activity is deemed by the Department for Energy and Mining (DEM), in consultation with relevant co-regulatory agencies, to be of medium impact according to the criteria for classifying the level of environmental impact of regulated activities then public comment is sought on the associated environmental impact report and draft statement of environmental objectives. All written submissions received in response to invitations for public comment under section 102 of the PGE Act are published in full on the DEM website as part of the Environmental Register, in accordance with the provisions of the PGE Act and Regulations. The content of these written submissions is not to be attributed to DEM nor to be taken as representative of any government view or position on the matters concerned. The use and reproduction of written submissions including third party attachments is at the risk of the user. These public consultation comments cover proposed proposed fracture stimulation in the Arckaringa Basin of South Australia.
