❓ Hon Robin Chapple asks about groundwater levels at Fortescue Marsh near FMG's Cloudbreak mine, specifically regarding baseline and trigger levels, changes since 2010, and monitoring data. The Minister provides baseline data, confirms no changes to trigger levels, and tables relevant compliance assessment reports.

QuestionView source ↗
I refer to the Fortescue Marsh, and to the Fortescue Metals Group (FMG) Cloudbreak mine operations, and the following monitoring bores (CBFMM01-CBFMM08 inclusive), and their respective locations: (720703 7531612), (727558.7 7527940), (734697 7527655), (746758 7523454), (740435.9 7524558), (751176 7521806), (755273 7520434), and I ask:
(a) what are the current baseline groundwater levels for each of the above bores;
(b) have baseline groundwater levels changed at any stage for any of the above bores since 1 January 2010;
(c) if yes to (b), can the Minister please state the baseline groundwater levels, as split out by bore and date of change(s), before and after any change(s) in baseline groundwater levels were made;
(d) if yes to (b), what were the reasons for those changes;
(e) if yes to (b), were these changes approved by the Department;
(f) what are the trigger groundwater levels for each of the above bores;
(g) have these trigger groundwater levels changed at any stage for any of the above bores since 1 January 2010;
(h) if yes to (g), can the Minister please state the trigger groundwater levels, as split out by bore and date of change(s), before and after the change(s) in trigger groundwater levels were made;
(i) if yes to (g), what were the reasons for those changes;
(j) if yes to (g), were these changes approved by the Department;
(k) can the Minister please table the annual results of monitoring, as submitted by FMG, for each of the years dating back to 1 January 2010;
(l) have groundwater levels, at any or all of the above-listed bores, risen or fallen by more than 1.0 metres from the baseline groundwater level, at any stage in any year, dating back to 1 January 2010;
(m) if yes to (l), on what dates did your Department receive notification(s) that groundwater levels at any or all of the above bores have risen or fallen by more than 1.0 metres from the baseline groundwater level;
(n) what is the function of the control bore; and
(o) how does the control bore differ from the groundwater monitoring bores listed above?
