New South Wales Consolidated Regulations New South Wales Consolidated Regulations(1) Local access rules may be applied once contoured recovery depths exceed the following piezometric decline (trigger level) in any key Department observation bore:
Year (of this plan) Trigger Level
(Metres decline)1 5.4 2 6.1 3 6.7 4 7.3 5 7.8 6 8.3 7 8.7 8 9.1 9 9.5 Note: A local impact area is to be identified from a map of the piezometric surface change, showing seasonal, annual or longer patterns of drawdown or recovery in an aquifer.
(2) Not withstanding subclause (1) local access rules may be applied once unacceptable impact from drawdown or recovery are observed in a single year or if the average piezometric decline across the water source of greater than 1.65 metres is likely to occur over the period of the Plan.
(3) Local access rules may be applied to reduce the rate of pressure decline, or in response to unacceptable seasonal drawdown or recovery, to ensure pressure recovery occurs to acceptable levels.
(4) Local access rules may be applied for such a time as required to stabilise and, if necessary, restore water levels or water pressures to an appropriate level, as determined by the Minister.
(5) This clause does not apply to local water utility access licences.
