accordance with clause 11 and any protocols adopted by the Authority under clause 40.

       (4) The Authority must review and amend each item on Register A and Register B in accordance with clause 24.

    18. Determining whether a Proposal has a Significant Effect

       (1) If a Contracting Government informs the Authority of a Proposal, the Authority must:

(a) investigate that Proposal; and

(b) decide whether the Proposal, either on its own or cumulatively with similar past actions or projected similar future actions, may have a Significant Effect.

       (2) If the Authority becomes aware of an action undertaken within a State after the relevant Baseline Date, of which the Authority has not previously been informed as a Proposal, but which the Authority considers has had or may have a Significant Effect, either on its own or cumulatively with similar past actions or projected similar future actions, it may direct the relevant State Contracting Government to inform the Authority of the action as a Proposal under sub‑clause 17(1).

       (3) A Significant Effect is:

(a) a change in average daily salinity at Morgan which the Authority estimates will be at least 0.1 E.C. within 100 years after the estimate is made; or

(b) a salinity impact which the Authority estimates will be significant.

       (4) To make an estimate referred to in sub‑clause 18(3), the Authority must use any relevant method for making that estimate set out in any protocols made by the Authority under clause 40.

    19. Assessing Salinity Impacts

       (1) If the Authority decides that:

(a) a Proposal referred to in sub‑clause 18(1); or

(b) an action referred to in sub‑clause 18(2),

        has or may have a Significant Effect, the Authority must:

(c) declare the Proposal or action to be an Accountable Action; and

(d) provisionally designate the Accountable Action to be in whole or in part either or both of a Joint work or measure and a State Action; and

(e) estimate the salinity impacts of the Accountable Action, using any relevant method for assessing salinity impacts set out in any protocols made by the Authority under clause 40.

       (2) If the Authority declares a Proposal or action to be an Accountable Action, the relevant Contracting Government must give to the Authority:

(a) all relevant information about the Accountable Action which may assist the Authority accurately to assess its salinity impacts;

(b) in such form as the Authority may require.

    20. Estimating Salinity Credits and Salinity Debits

       (1) After the Authority has estimated the salinity impacts of an action which the Authority considers may be an Accountable Action under clause 19, it must:

(a) subject to sub‑clause 20(2), estimate the prospective salinity credits or salinity debits arising from that action; and
