2  Simplified outline of this Schedule

      This Schedule sets out how to calculate the SDL adjustment amount of each surface water SDL resource unit for each water accounting period. The SDL adjustment amount is used to calculate the long term average sustainable diversion limit of each surface water SDL resource unit.
      The SDL adjustment amount is expected to vary between water accounting periods, as:
         ● water access entitlements are progressively acquired in conjunction with, or to take advantage of the water savings achieved by, notified efficiency measures. Such acquisitions will be efficiency entitlements in different surface water SDL resource units, increasing the efficiency contributions in affected units; and
         ● the overall limitation on the size of adjustment amounts under section 7.19 operates, if applicable, in relation to a particular water accounting period.
      Section 7.19 of the Basin Plan applies if, at a particular time, the net effect of the total supply contribution and the total efficiency contribution (referred to in this Schedule as the "net effect") represents an increase or a decrease of more than 5% of the total surface water SDL for the Basin water resources as it stood at the reference time. The total surface water SDL for the Basin water resources as it stood at the reference time is equal to 10,873 GL per year, and 5% of that amount is equal to 543 GL per year (when rounded down).
      On the basis of the supply measures and efficiency measures that were notified to the Authority by 30 June 2017, the net effect will not represent a decrease of more than 5% of this amount. Accordingly, the formula set out in this Schedule provides for a reduction only of the supply contribution for affected units, and not of the efficiency contributions.
      As efficiency contributions are expected to vary over time, the net effect is also expected to vary. Section 4 of this Schedule sets out how to assess the magnitude of the net effect.
      Net effect greater than 543 GL per year
      For water accounting periods for which the net effect exceeds 543 GL per year, SDL adjustment amounts are calculated in accordance with section 5 of this Schedule. For such water accounting periods, the formula additionally reflects the operation of the overall limit on adjustments in section 7.19 of the Basin Plan.
      Net effect no greater than 543 GL per year
      If, however, for a particular water accounting period, the net effect does not exceed 543 GL per year, the SDL adjustment amount for each surface water SDL resource unit is instead calculated in accordance with section 6 of this Schedule.
      In both cases, in accordance with paragraph 7.20(4)(b) of the Basin Plan, the adjustments are
