Premium Content Subscriber only An investigation into alleged “serious pollution and environmental damage” on the Carmichael mine rail corridor is continuing, with experts called in to help with the probe. The group alleged this was because Bravus Mining and Resources had failed to properly prepare construction sites on the rail corridor for the wet season. The conditions required the development and implementation of erosion and sediment control measures. Mackay Conservation Group provided photos – taken about two weeks after heavy rainfall in December – of what it claimed were the alleged breaches. An office of the Coordinator-General spokeswoman said it had received advice from independent experts engaged to help with an investigation into allegations of a breach of conditions within the Galilee Basin State Development Area.
