I refer to question on notice No. 532 of March 11 2003 and answers provided -
(1) Is KCGM the operator of these premises specifically with the Fimiston I and Fimiston II tailings dams currently permitted under its licence conditions to contaminate surface or underground waters with cyanide?
(2) If yes to (1), why has the Department of Environmental Protection given KCGM this special privilege of being able to do this?
(3) If no to (1), can the Minister state the specific text of the current licence which clearly prevents or stops KCGM from contaminating surface or underground waters with cyanide from the Fimiston I and Fimiston II tailings dams at these premises?

This includes but is not limited to tailings storage facilities, return water dams and raw water dams. W4(a) The licensee shall ensure that all pipelines containing saline, alkaline or cyanide constituents are either buried or sited within appropriately bunded facilities. This includes but not limited to tailings delivery lines, return water lines and saline water lines. W4(b) Where pipelines are situated above ground, the licensee shall ensure that catch pits are sited at appropriate low points along the pipeline route to enable the containment of spills. W5 The licensee shall undertake visual inspections of the tailings storage facilities (TSF) at least every six hours. As a minimum, the following areas shall be inspected: (i) tailings delivery lines; (ii) return water lines; (iii) tailings deposition; (iv) ponding on the surface of the tailings storage facilities; (v) internal embankment freeboard; and (vi) the external wall of the TSF. A log book shall be filled in after every inspection. The log book shall be signed by the person conducting the inspection and shall be kept in the plant control room. W11(a) The licensee shall take representative water samples from the bores, at the frequencies stated, and have them analysed for the parameters listed in the Attachment 1. See tabled paper. W11(b) The licensee shall provide a copy of the results of the above sampling programme to the Department of Environmental Protection’s Regional office in Kalgoorlie. The reports shall be submitted to the DEP within 6 weeks of the end of each sampling period. W11(c) The samples identified by condition W11(a) shall be collected and preserved as described in Australian Standard 5667.1-1998, then submitted to an approved laboratory for analysis in accordance with "Standard Methods for Examination of Water and Wastewater-APHA-AWWA-WEF", or in accordance with a method and by a laboratory approved by the Director.
