(2) New South Wales, Victoria and the Commission must ensure that:
(a) the Translation Factors are determined in a manner consistent with the principles used to determine exchange rates in the relevant Water Market at the time of each transfer under sub-clause 18(2) of this Schedule; and
(b) the use of Translation Factors to transfer Water Savings and Water Entitlements to a Snowy-Murray Development (River Murray) Environmental Entitlement will not have a significant adverse impact on:
(i) the level of Reliability of entitlements to water diverted from the River Murray System, the Murrumbidgee River System and the Goulburn River System;
(ii) the environmental benefits related to the quantity and timing of water flows for environmental purposes in the River Murray System, the Murrumbidgee River System and the Goulburn River System;

New South Wales and Victoria must notify the Commission of how each Environmental Entitlement has been apportioned between:
(1) the Snowy River Apportioned Entitlement; and
(2) the River Murray Apportioned Entitlement.
If:
(1) New South Wales or Victoria transfers either or both of Water Savings and Water Entitlements to an Environmental Entitlement; and
(2) the source of that water is from a valley for which the Commission maintains a valley account,
New South Wales or Victoria (as the case may be) must notify the Commission of the volume and reliability of the entitlement required to be added to the relevant valley account to generate the Environmental Entitlement.
(1) Prior to New South Wales or Victoria transferring either or both of Water Savings and Water Entitlements to an Environmental Entitlement, the relevant State must calculate the equivalent volume by which its Long Term Diversion Cap must be reduced.
(2) If New South Wales or Victoria transfers either or both of Water Savings and Water Entitlements to an Environmental Entitlement, at the same time the relevant State must advise the Commission of its calculation as to the volume by which its Long Term Diversion Cap must be reduced.
(3) If the Commission is satisfied with the appropriateness of a calculation advised under sub-clause 18(2), it must recommend to the Ministerial Council that the relevant Long Term Diversion Cap be amended in accordance with the calculation.
(4) If the Commission is not satisfied with the appropriateness of a calculation advised under sub-clause 18(2), the Commission must arrange for the relevant volume referred to in sub-clause 18(1) to be re-calculated in consultation with the relevant State.
(5) If a majority of the Commissioners is satisfied with the appropriateness of a calculation made under sub-clause 18(4), the Commission must recommend to the Ministerial Council that the relevant Long Term Diversion Cap be amended in accordance with the calculation.

PART V: RIVER MURRAY INCREASED FLOWS
19. Obligation Of Commission To Make River Murray Increased Flows
Subject to this Part, the Commission must release River Murray Increased Flows.
20. Environmental Objectives And Strategy For River Murray Increased Flows
(1) Before the commencement of the second complete Water Year after the Corporatisation Date, the Ministerial Council must determine:
(a) a strategy for retaining and releasing River Murray Increased Flows to be implemented by the Commission; and
(b) the environmental objectives for the River Murray Increased Flows,
in accordance with the provisions of this clause.
(2) The Strategy:
(a) must include a provision to the effect that River Murray Increased Flows have first priority from River Murray Above Target Releases;
(b) may provide that water credited to the River Murray Increased Flows in Commission Storages Account need not be released during the Water Year in which it is credited;
(c) unless the Ministerial Council otherwise determines, must not have a significant adverse impact upon the security of entitlements to water;
(d) must integrate the environmental objectives for the River Murray Increased Flows with other environmental initiatives on the River Murray;
(e) must include adaptive management principles to allow the ability to optimise environmental benefits; and
(f) must prescribe appropriate environmental reporting and monitoring conditions.
(3) The Ministerial Council must determine the environmental objectives and Strategy in accordance with the following principles:
(a) Natural diversity of habitats and biota within the river channel, riparian zone and the floodplain should be maintained or enhanced.
(b) Natural linkages between the river and the floodplain should be maintained or enhanced.
(c) Natural metabolic functioning of aquatic ecosystems should be maintained or enhanced.
(d) Elements of the natural flow regime, in particular, seasonality should be retained or enhanced as far as possible, in the interests of conserving a niche for native rather than invasive exotic species and in maintaining the natural functions of the river.
(e) Consistent and constant flow and water level regimes should be avoided where practical, as this is contrary to the naturally variable flow regime of the River Murray.
(f) The general principles of ecosystem services should be recognised.
(g) Environmental benefit should be optimised.
(4) The Ministerial Council may from time to time by resolution amend the environmental objectives and the Strategy.
(5) As soon as practicable after the end of each Water Year, the Commission must report to the Contracting Governments on the environmental outcomes of the River Murray Increased Flows during that Water Year, in the light of the objectives determined by the Ministerial Council for those Increased Flows.

(a) credit the Initial River Murray Increased Flows Account with the River Murray Annual Allocation notified by New South Wales;
(b) transfer from the Initial River Murray Increased Flows Account to the River Murray Increased Flows in Commission Storages Account, River Murray Above Target Releases allocated to the River Murray Increased Flows in accordance with the Strategy;
(c) record in the River Murray Increased Flows in Commission Storages Account the transfer of water in that account between Commission storages; and
(d) record in the River Murray Increased Flows in Commission Storages Account the release of River Murray Increased Flows from Commission storages.
(3) The River Murray Increased Flows Accounts must be independently audited unless the Commission by resolution declares otherwise.
(4) As soon as practicable after the completion of each audit, the Commission must send a copy of the audited River Murray Increased Flows Accounts to the Contracting Governments.
The Commission must commence to implement the Strategy on the later of:
