QuestionView source ↗

I refer to the Fimiston 2 tailings dam and the recent proposal to raise the height and capacity of the dam, Prospecting Licence 26/1848 and the Independent Technical Review Thompson and Brett report dated October 2004 -
(1) Is it correct that part of the Thompson and Brett Report dated October 2004 states ‘Figure 3 also suggests that some seepage is flowing past the borefield but that is predominantly from Fimiston 2. To fully intercept all seepage it would be necessary to develop a broad groundwater sump. This has so far not been achieved’?
(2) If no to (1), will the Minister quote the full text from the report dated October 2004?
(3) Will the Minister or Department of Environment (DoE) reject KCGM’s proposal to raise the height and capacity of the Fimiston 2 dam, until KCGM has produced a plan which clearly aims to fully intercept all seepage with a broad groundwater sump as advocated by Thompson and Brett, or a series of very deep benched down trenches including more production bores so as contaminated water does not continue to spread downstream?
(4) If no to (3), why not?
(5) If the DoE has determined that it is not practicable to fully intercept all seepage with a broad groundwater sump or a series of very deep benched down trenches including more production bores, will the Minister or the DoE reject KCGM’s proposal to raise the height and capacity of the Fimiston 2 tailings dam as being environmentally unacceptable, given that contaminated water will continue to spread downstream?
(6) If no to (5), why not?
