components began in November 2012 and the Brine Concentrator is expected to be commissioned and fully operational in Q3 2013. The Brine Concentrator has the capacity to produce 1.83 gigalitres of clean water per year through the treatment of process water. Hatch was appointed EPCM contractor for the Brine Concentrator project. It was successfully commissioned in November 2013 with a budget of AUD $220 Million dollars. In 2012, ERA and the Mirarr Traditional Owners represented by the Gundjeihmi Aboriginal Corporation (GAC), conducted a jointly facilitated independent expert review of the quality of surface water around the Ranger Project Area. The Independent Surface Water Working Group consisted of representatives from ERA, GAC, the Supervising Scientists Division and the Northern Land Council. Over a six-month period, the working group examined the impacts, monitoring and reporting of surface water flowing from the Ranger mine. The working group agreed in findings released in March 2013 that the current surface water management and regulatory systems in place at the Ranger mine are of a very high standard. Going forward, the Group has agreed upon an action plan to ensure that surface water management systems at Ranger remain best leading practice. Safety breaches and controversy Environment Australia (an agency of the Government of Australia) have documented over 200 environmental incidents since 1979. The great majority of these were minor, but the significant ones are detailed below. In 2013, a spokesperson from the Public Health Association of Australia claimed that there had been a hundred safety incidents linked to the mine in the thirty years prior. In May 2005 the company was convicted for breaching environmental guidelines - the first such prosecution of a mining company in the Northern Territory, relating to accidental radiological exposure to ERA employees. Radioactively contaminated process water had entered the drinking water supply and some workers drank and washed in it. Dozens of mine employees were found to have showered in and consumed water containing 400 times the legal limit of uranium. The maximum radiation exposure of workers was likely to have been much less than the regulatory limit, and no harmful long-term health effects are likely. Other incidents involving decontamination of vehicles have been identified. When the work-for-welfare mechanic in Jabiru opened the engine bay, he was unaware of the nature of the mud and dirt which fell on the floor. The court heard that in the following weeks, after he
