The Tiwest Joint Venture (TJV), the proponent, proposes to increase the production of finished titanium dioxide pigment at its Kwinana Pigment Plant. The Tiwest Joint Venture has requested changes to Condition 1 of the Ministerial Statement of 26 April 1989, relating to the Pigment Plant. Condition 1 restricts the original plant to 54,000 tonnes per annum of finished titanium dioxide pigment, as assessed by the Environmental Protection Authority in Bulletin 373. The proponent now proposes to undertake a "de-bottlenecking" process so that the plant can be rated to 64,000 tonnes per annum of finished titanium dioxide pigment.
