For ALL marine All Toxicants in water and sediment as per AWQG (2000):
and estuarine Toxicants in water: refer to AWQG section 3.4 - ‘water quality
waters within this guidelines for toxicants’ (including Tables 3.4.1, 3.4.2, and
Table Figure 3.4.1)
Toxicants in sediments: refer to AWQG section 3.5 - ‘sediment
quality guidelines’ (including Table 3.5.1, Figure 3.5.1)
Release of sewage from vessels to be controlled in accordance with
requirements of the Transport Operations (Marine Pollution) Act and
