56 Release of water, other than stormwater, to surface water

(1) This section applies to the administering authority for making an environmental management decision relating to an activity that involves, or may involve, the release of water, other than stormwater, to surface water.

(2) The administering authority must consider each of the following matters--

(a) any available toxicity data relevant to the release and the receiving environment;
(b) if there is an initial mixing zone--
(i) whether there is any practicable alternative that would reduce or eliminate the initial mixing zone; and
(ii) whether the size of the initial mixing zone is likely to adversely affect an environmental value or the ecological condition of the receiving environment, including, for example, a watercourse or wetland; and
(iii) whether concentrations of contaminants in the initial mixing zone are acutely toxic to the biota.

(3) The administering authority must also consider whether to impose conditions about the following matters--

(a) releasing the water to tidal waters only during particular tidal conditions, including, for example, phases of the moon;
(b) releasing the water to non-tidal waters only if the rate of flow of the surface water is greater than a particular level.
