37 Water level management

(1) The Minister may declare that, in order to protect water levels within these groundwater sources, local access rules are to apply in a defined area known as a local impact area.

(2) The following extraction restrictions shall apply to extraction from all water supply works (bores) within a local impact area declared under subclause (1) nominated by an access licence, and will be based on monitoring bores or predictive models where monitoring bores are not installed:

(a) when groundwater levels in an area remain above, or recover to, the 80 th percentile exceedance level, extraction from water supply works (bores) nominated by an access licence in the area will be in accordance with the water supply work approval and access licence conditions, and annual available water determinations,

(b) when groundwater levels are between the 80 th and 90 th percentile exceedance levels, quarterly volumes extracted from water supply works (bores) nominated by an access licence in the affected area shall not exceed one sixth of the access licence annual available water determination,

(c) when groundwater levels are between the 90 th and 95 th percentile exceedance levels, quarterly volumes extracted from water supply works (bores) nominated by an access licence in the affected area shall not exceed one twelfth of the access licence annual available water determination,

(d) when groundwater levels are at or below the 95 th percentile exceedance level, extraction shall cease from water supply works (bores) in the affected area nominated by an access licence,

(e) subclauses (a) to (c) do not apply to extraction under local water utility access licences,

(f) when groundwater levels in an area remain above, or recover to, the 90 th percentile exceedance level, extraction from water supply works (bores) nominated by a local water utility access licence in the area will be in accordance with the water supply work approval and access licence conditions, and annual available water determinations,

(g) when groundwater levels are between the 90 th and the 95 th percentile exceedence level, quarterly volumes extracted from water supply works (bores) nominated by a local water utility access licence in the affected area shall not exceed one sixth of the access licence share component, and

(h) when groundwater levels are at or below the 95 th percentile exceedance level, quarterly volumes extracted from water supply works (bores) nominated by a local water utility access licence in the affected area shall not exceed one twelfth of the access licence share component.

Note: Water supply work approval and access licence holders will be advised as soon as possible if extraction restrictions are going to apply in accordance with this clause.

Note: This provision recognises that in some locations, at certain periods of high groundwater demand, critical water level declines may occur, and that additional extraction limitations may be required. The Department of Land and Water Conservation will identify monitoring bores, and determine the method for specifying an affected area.
