(5) If a right, or a part of a right, specified in reliance on subsection (4) was an efficiency entitlement or additional efficiency entitlement, it ceases to be an entitlement of that kind.

        Part 2—Adjustment of surface water SDLs

        Division 1—Objective

7.09 Objective
  The objective for this Part is to allow surface water SDLs to be adjusted to reflect the effects of:
            (aa)  measures that increase the supply of water or the efficiency of water use, and are notified under this Part; and
            (ab)  additional HEW entitlements specified under section 7.08B;
            so that:
            (a) for efficiency measures—environmental outcomes are increased while maintaining or improving social and economic outcomes; and
            (b) for supply measures—equivalent environmental outcomes are achieved with a lower volume of held environmental water than would otherwise be required; and
Note: Some jurisdictions anticipate that such measures may be able to provide the equivalent of 650 GL per year of water, reducing the quantity of water access rights the Commonwealth will need to acquire to 'bridge the gap'.
            (c) where constraints on the capacity to deliver environmental water are removed or eased—available environmental water can be used to maximum effect; and
            (d) enhanced economic, social and environmental outcomes compared with the benchmark environmental outcomes and benchmark conditions of development can be achieved for the Murray‑Darling Basin, including through more efficient water use, improved river operations, improved outcomes for the River Murray floodplain, River Murray river water quality, estuarine health, Murray Mouth opening, higher average lake levels and increased in‑stream flows and variability; and
            (e) the easing or removal of constraints and the addition of 450 GL per year of environmental water above the 2750 GL benchmark conditions of development, under the Commonwealth's program, allow the enhanced environmental outcomes as set out in Schedule 5 to be pursued as compared to the benchmark environmental outcomes.
Note 1:  The Commonwealth program to ease or remove capacity constraints and deliver 450 GL of additional environmental water is to improve the environmental outcomes beyond those achievable under the 2750 GL benchmark by a further 450 GL and thus pursue the environmental outcomes set out in Schedule 5 that reflect the results of the 3200 GL per year modelling with relaxed constraints scenario reported in: MDBA (Murray‑Darling Basin Authority) 2012, Hydrologic modelling of the relaxation of operational constraints in the southern connected system: Methods and results, MDBA publication no: 76/12, Murray‑Darling Basin Authority, Canberra. http://download.mdba.gov.au/altered‑PBP/Hydrologic‑modelling‑relaxed‑constraints‑October‑2012.pdf
Note 2: The Commonwealth's program referred to in paragraph (e) includes the program that is expected to spend $1.77 billion by 31 December 2027 under the Water for the Environment Special Account.
