Note: See Schedule 2, and the definition of SDL adjustment amount in section 6.05A.
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. See subsection 6.04(3), column 2 of the table in Schedule 2, and the definition of “SDL adjustment amount” in section 6.05A.
● water access entitlements are progressively acquired in conjunction with, or to take advantage of the water savings achieved by, notified efficiency measures and additional efficiency measures. Such acquisitions will be efficiency entitlements in different surface water SDL resource units, increasing the efficiency contributions in affected units; and
● additional water access rights, water delivery rights and irrigation rights are progressively acquired. Such acquisitions will be additional HEW entitlements in different surface water SDL resource units, increasing the additional HEW 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 applies if, at a particular time, the net effect of the total supply contribution, the total efficiency contribution and the total additional HEW 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 and any additional efficiency measures notified under section 7.12 or additional HEW entitlements specified under section 7.08B, 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 and additional HEW contributions.
As efficiency contributions and additional HEW contributions are expected to vary over time, the net effect is also expected to vary. Section S6A.04 sets out how to assess the magnitude of the net effect.
For water accounting periods for which the net effect exceeds 543 GL per year, SDL adjustment amounts are calculated in accordance with section S6A.05 of this Schedule. For such water accounting periods, the formula additionally reflects the operation of the overall limit on adjustments in section 7.19.
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 S6A.06 of this Schedule.
In both cases, the adjustments are expressed in the form of a formula as a function of time, changing at specified times (namely, at the beginning of each water accounting period), that reflects the changes to the efficiency contributions and additional HEW contributions over time.

Note: The current efficiency contribution for a surface water SDL resource unit might vary between water accounting periods, as relevant water access entitlements are acquired.
Note 1: The net effect is the difference between the total supply contribution on the one hand, and the total efficiency contribution and total current additional HEW contribution on the other for the water accounting period under sections 7.15 to 7.17.
Note 2: The net effect might vary between water accounting periods as the total efficiency contribution and total current additional HEW contribution change with time.
total current additional HEW contribution for a particular water accounting period, is equal to the sum of the current additional HEW contributions of all surface water SDL resource units.
total current efficiency contribution, for the water accounting period, is equal to the sum of the current efficiency contributions of all surface water SDL resource units.
(2) For paragraph (a) of the definition of “apportioned supply contribution” in subsection (1), the table is the following:

(i) the long‑term average sustainable diversion limit for the surface water SDL resource unit given by Schedule 2 as in force when the Basin Plan first took effect; and
(ii) the SDLs for each groundwater SDL resource unit as at the time the Basin Plan first took effect (see subsection 6.04(4)).
Part 2—Calculation of SDL adjustment amount
(1) The calculation of the SDL adjustment for each surface water SDL resource unit in a water accounting period depends on whether the net effect for that water accounting period would represent an increase of more than 5% of the total surface water SDL for the Basin water resources as it stood at the reference time.
Note: The total surface water SDL for the Basin water resources as it stood at the reference time is 10,873 GL per year, and 5% of that amount is 543 GL per year (when rounded down).

Start formula open bracket net effect close bracket equals 605 minus open bracket total current efficiency contribution close bracket minus open bracket total current additional HEW contribution close bracket end formula
Note: The net effect will be greater than 543 GL per year only if the sum of the total current efficiency contribution and the total current additional HEW contribution is less than 62 GL per year.
(2) The SDL adjustment amount for a particular surface water SDL resource unit for the water accounting period, in GL per year, is calculated in accordance with the following formula:

apportioned supply contribution, for the surface water SDL resource unit, has the meaning given by subsection S6A.02(1).
Note 1: The amount 543 GL per year is equal to 5% of the total surface water SDL for the Basin water resources as it stood at the reference time (that amount being 10,873 GL per year) (when rounded down).
(2) The SDL adjustment amount for a particular surface water SDL resource unit for the water accounting period, in GL per year, is calculated in accordance with the following formula:
Start formula open bracket SDL adjustment amount close bracket equals open bracket apportioned supply contribution close bracket minus open bracket current efficiency contribution close bracket minus open bracket current additional HEW contribution close bracket end formula
