WATER SHARING PLAN FOR THE MURRUMBIDGEE REGULATED RIVER WATER SOURCE 2003 - REG 62

62 Provisional storage volume

(1) A first provisional storage volume (hereafter "PSV1") shall be established for the purposes of increasing the size and frequency of spill events and to increase water availability in the following season.

(2) Each water year, the PSV1 shall be credited with water as it becomes available according to:

(a) when the sum of water allocations from available water determinations for regulated river (general security) access licences plus water allocations carried over in the water allocation accounts of regulated river (general security) access licences from the previous water year are equivalent to or greater than 0.6 megalitres multiplied by the total number of unit shares specified in share components of regulated river (general security) access licences, and provision has been made for the volume determined under clause 15 (8) for the EWA1, the next 25,000 megalitres of water available shall be credited to the PSV1 prior to any further resources being made available to regulated river (general security) access licences, and

(b) when the sum water allocations from available water determinations for regulated river (general security) access licences plus water allocations carried over in the water allocation accounts of regulated river (general security) access licences from the previous water year are equivalent to or greater than 0.8 megalitres multiplied by the total number of unit shares specified in share components of regulated river (general security) access licences, and provision has been made for the volume determined under clause 15 (10) to be credited to the EWA3, 8,750 megalitres shall be credited to the PSV1 for every additional 0.01 megalitre per unit share of available water determination made for regulated river (general security) access licences.

(3) A second provisional storage volume (hereafter "PSV2") shall be established for the purposes of increasing the size and frequency of spill events and to increase water availability in the following season.

(4) The PSV2 shall be operated according to the following:

(a) when the sum of water allocations from available water determinations for regulated river (general security) access licences plus water allocations carried over in the water allocation accounts of regulated river (general security) access licences from the previous water year are equivalent to or greater than 0.8 megalitres multiplied by the total number of unit shares specified in share components of regulated river (general security) access licences and provision has been made for the volumes of water determined in clause 15 (10) for the EWA3 and subclause (2) for the PSV1, any additional water shall be credited to the PSV2, up to the volume that was forfeited at the end of the previous water year, prior to any further resources being made available to regulated river (general security) access licences,

(b) if, by the end of the water year, there remains PSV2 water from the previous water year that cannot be credited under subclause (4) (a), it will be forfeited permanently,

(c) on 1 November, 50% of the EWA3 shall be transferred to the PSV2 as per clause 15 (10) (c) (vi),

(d) from 1 November, when the sum of water allocations from available water determinations for regulated river (general security) access licences plus water allocations carried over in the water allocation accounts of regulated river (general security) access licences from the previous water year are equivalent to or greater than 0.8 megalitres multiplied by the total number of unit shares specified in share components of regulated river (general security) access licences and provision has been made for the volumes of water determined in clause 15 (10) for the EWA3 and subclause (2) for the PSV1, any additional water shall be credited to the PSV2 prior to any further resources being made available to regulated river (general security) access licences,

(e) the PSV2 shall be credited under subclause (d) to a maximum limit which is the sum of water calculated under clause 15 (10) (a) that has not been credited to the EWA3 in that water year and any water calculated under clause 15 (10) (a) that has not been credited to the EWA3 in the preceding water year,

(f) on 1 January all remaining water in the EWA3 shall be transferred to the PSV2 as per clause 15 (10) (c) (vii),

(g) the PSV2 shall be forfeited at the end of each water year,

(h) during any flow event where water is spilled from Burrinjuck Dam water storage or Blowering Dam water storage, the PSV2 will not be reduced, regardless of whether the water was accrued in that water year or carried over from the previous water year, and

(i) at the commencement of this Plan the maximum limit for PSV2 shall be equivalent to the PSV2 (or equivalent) balance that exists immediately prior to the commencement of this Plan.

Note: This PSV2 has been established to account for water that had been released under previous translucent release rules using Schedule 4, but is no longer released under this Plan using Schedule 5.

(5) Pursuant to section 45 (1) (b) of the Act and clause 72 of this Plan, the Minister may amend the provisional storage volume rules under this clause to the extent specified in clause 72.
