S6A.03  Proposed plan area limits and proposed Basin limit
  For subsection 23B(4) of the Act:
 (a) the proposed plan area limit (within the meaning of subsection 23A(5) of the Act) for each surface water SDL resource unit is equal to the sum of:
 (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
 Note: The Basin Plan first took effect on 24 November 2012.
 (ii) the SDL adjustment amount for the surface water SDL resource unit; and
 (b) the proposed Basin limit (within the meaning of subsection 23A(5) of the Act) is equal to the sum of:
 (i) the proposed plan area limits as referred to in paragraph (a) for all surface water SDL resource units; 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

S6A.04  Net effect of the total supply contribution and the total efficiency contribution
 (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).
 (2) For a particular water accounting period, the net effect, in GL per year, is calculated in accordance with the following formula:

  where:
total current efficiency contribution has the meaning given by subsection S6A.02(1).
total current additional HEW contribution has the meaning given by subsection S6A.02(1).
Note:  The amount 605 GL per year is the total supply contribution.

S6A.05  Calculation of SDL adjustment amounts—net effect greater than 543 GL per year
 (1) This section applies if, for the water accounting period, the net effect is greater than 543 GL per year.
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:

  where:
reduced supply contribution, for the surface water SDL resource unit and the water accounting period,
