97 Acid sulphate soils The concerns of Wasson et al (1998) that heavy metals accidentally released from the mine site could be mobilised into downstream ecosystems by the acid sulphate soils and that the pumping of water from a billabong could lead to increased acidity in surface waters are not justified. Experience at the Ranger mine has shown that in every case where accidental releases have occurred, the total load of any metals released is extremely small compared to the natural load of metals in the soils of the floodplain. The previous proposal to re-establish the old Ja-Ja camp has been withdrawn and there are no plans to pump large quantities of water from the billabong. Rehabilitation of the Jabiluka lease area ERA is required to rehabilitate the Jabiluka mine site in a manner which will establish an environment in the lease area that reflects, to the maximum extent that can reasonably be achieved, the environment existing in the adjacent areas of Kakadu National Park. The intention is that the rehabilitated area could be incorporated into the Kakadu National Park without detracting from park values. The Government has established secure mechanisms to ensure that these rehabilitation objectives will be achieved even if the company becomes insolvent and ceases operations prior to the completion of adequate rehabilitation of the sites. Transport of uranium from the Jabiluka mine The transport of uranium product from Jabiluka to the Port of Darwin through Kakadu National Park is governed by laws of the Northern Territory which include the total text of the International Atomic Energy Agency Regulations for the Safe Transport of Radioactive Material. Two emergency trailers and trained emergency response crews are on call for each consignment of uranium product. The trailers contain equipment that would allow the crew to safely collect any spilled uranium product. The hazards associated with spillage of uranium product have been carefully assessed and emergency procedures have been developed to ensure that both people and ecosystems will be protected in the event of an accident. There has never been a transport accident involving the release of uranium product during the life of the Ranger mine.
