I refer to the
Environmental Protection Act 1986
licence dated February 14 2005 signed by Ross Sheridan, Acting Regional Manager, Swan Goldfields Agricultural Region, addressed to the Manager, Polymetals (WA) Pty Ltd concerning the Nimbus Gold Mine -
(1) Is it correct that condition W4(a) states ‘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 is not limited to tailings delivery lines, return water lines and saline water lines’?
(2) If no to (2), will the Minister specifically quote the text of condition W4(a)?
(3) Can the Minister state what is the importance under the
Environmental Protection Act 1986
of making Polymetals spend money to comply with condition W4(a)?
(4) If no to (1), will the Minister quote the specific text of the condition?
(5) Can the Minister state how many breaches of licence conditions, whether prosecuted or not, that the licensee has breached on it licences since the Nimbus Mine first commenced operation up to present date, the specific text of the condition breached and what, if any, enforcement action that followed from the Department?
(6) If no to (5), why not?
(7) Has the Department identified any vegetation damage, pollution being caused from the tailings dams since the tailings dam was first commissioned up till present date?
(8) If yes to (7), on what specific dates and how much of an area in square metres was affected?
(9) Can the Minister state what is the depth to groundwater from the surface in metres below ground level of the water table surrounding the tailings dam?
(10) If no to (9), why not?
(11) Can the Minister state what is the depth to groundwater from the surface in metres below ground level of the water table, if any, prior to the deposition and commencement of the tailings dam in the area?
(12) If no to (11), why not?

The Minister for the Environment; Science has provided the following response: (1) Yes. (2) Not applicable, though it is presumed this was meant to reference question (1). (3) The Department of Environment (DoE) considers pipeline bunding a practical measure to minimise the impact of spills on environmental values of the area. In general, pipeline spills will occur on the land surface and be in direct contact with flora and fauna. The appropriate use of bunding can minimise the impact of any spill. (4) Not applicable, though it is presumed this was meant to reference question (3). (5) There have been no known breaches recorded for this site. (6) Not applicable. (7) No. (8) Not applicable. (9) The DoE understands that groundwater monitoring bores have been installed around the Tailings Storage Facility to a depth of 30 metres. To date, monitoring of these bores has not recorded any groundwater. Therefore the water table surrounding the tailings dam is greater than 30 metres below ground level. The monitoring bore depth of 30 metres is considered practical given that the target is to keep groundwater at least four metres below ground level in the southern Goldfields. In most of the Goldfields area the regional groundwater is hyper-saline (saltier than sea water) and the vegetation of the region does not use this water for its growth. Rather it is understood that the eucalyptus species rely on the relatively even spread of summer and winter rainfalls being retained in the upper soil profile. (10) Not applicable. (11) The DoE understand that the water table prior to deposition of tailings was 75 metres below ground surface. These levels were determined through the exploration undertaken prior to constructing the tailings storage facility. (12) Not applicable.
