(1) The long term average annual extraction from this water source may not be
permitted to exceed the long term extraction limit specified in clause 28.
(2) Pursuant to subclause (1):
(a) if it has been assessed that the current
long term average annual extraction from this water source exceeds the
long term extraction limit by 3% or more, then the maximum available water
determination made for supplementary water access licences in this water
source under clause 38 shall be reduced, and
(b) if necessary, the maximum
volume that may be taken or assigned from a regulated river (general
security--A class) and a regulated river (general security--B class) access
licence under clause 31 shall be reduced.
(3) The degree of reduction under
subclause (2) shall be that which is assessed as necessary to return long term
average annual extractions to the long term extraction limit.
(4) If action
has been taken under subclause (2), and a subsequent assessment under clause
29 indicates that the current long term average annual extraction is below the
long term extraction limit by more than 3%, then previous reductions made
under subclause (2) may be reversed to the degree that it is as assessed
necessary to return the long term average annual extractions to the
long term extraction limit.
(5) Any reversal of a previous reduction under
subclause (4):
(a) shall not exceed any previous reductions made under
subclause (2), and
(b) shall first reverse any previous reductions relating
to regulated river (general security--A class) and regulated river (general
security--B class) access licences.
(6) The assessment of the degree of any
reduction required under subclause (2) or the degree of any reversal under
subclause (4) shall be made using the same computer model used to carry out
assessments under clause 29.
(7) Following an amendment made under clause 28
(4) the Minister may amend clause 30 to include rules for managing floodplain
harvesting extractions within the relevant long term extraction limit.
