"It does seem to be a bit of a circus," she said. "I mean it seems to be that its an ailing plant that the plant management there just don't seem to be able to operate effectively. "They haven't made it through 24 hours of operation so to me it seems like there doesn't seem to be control of the equipment that they have there." Minister for Environment Robyn Parker says while Orica notified the EPA about the spill immediately, another incident is unacceptable. "Orica has issues to address it is unacceptable, it's an ongoing problem," she said. " What we need to know from Orica is how they are going to address their ongoing concerns. "The community needs to have confidence in Orica and currently that confidence is very much shaken."
