Environmental Quality Standards The EQS for sediment nutrients are outlined in Table 4.6. Table 4.6 EQS for sediments EQS Indicator Sediments TKN TP TOC (LOI) Redox discontinuity Moderate Zone of Ecological Protection High Maximum If EQG (i) and/or (ii) is exceeded and the exceedance is based on the moderate protection guideline (95%): (i) Evaluation of images taken beneath and within 10 m of the sea-cages must not indicate presence of white bacterial matts, black sediments, bubbles of hydrogen sulphide or a significant reduction in the presence of animal tracks, or bioturbator burrows, relative to Reference Sites, or (ii) Sediment infauna community species richness, based on the Inverse Simpson Index, not to be five times less than background (indicative of moderate impact), or (iii) Median bottom water DO on each sampling occasion must be greater than 60% saturation and not the result of a regional event as indicated by similar reductions in DO at the Reference Sites, or (iv) Median bottom water DO at any site over a four month period must be greater than 60% saturation If EQG (i) and/or (ii) is exceeded and the exceedance is based on the high protection guideline (80%ile): Proceed to EQS for high and maximum protection If EQG (i) and/or (ii) is exceeded and the exceedance is based on the moderate protection guideline (95%): (i) Evaluation of images taken beneath and within 10 m of the sea-cages must not indicate presence of white bacterial matts, black sediments, bubbles of hydrogen sulphide or a significant reduction in the presence of animal tracks, or bioturbator burrows, relative to Reference Sites, or (ii) Sediment infauna community species richness, based on the Inverse Simpson Index, not to be five times less than background (indicative of moderate impact), or (iii) Median bottom water DO on each sampling occasion must be greater than 60% saturation and not the result of a regional event as indicated by similar reductions in DO at the Reference Sites, or (iv) Median bottom water DO at any site over a four month period must be greater than 60% saturation If EQG (i) and/or (ii) is exceeded and the exceedance is based on the high protection guideline (80%ile): Proceed to EQS for high and maximum protection (i) Sediment infauna community species richness, based on the Inverse Simpson Index, not to be less than half that of background (indicative of minor impact), or (ii) Median bottom water DO on each sampling occasion must be greater than 60% saturation and not the result of a regional event as indicated by similar reductions in DO at the Reference Sites, or (iii) Median bottom water DO at any site over a four month period must be greater than 60% saturation (i) Sediment infauna community species richness, based on the Inverse Simpson Index, not to be less than half that of background (indicative of minor impact), or (ii) Median bottom water DO on each sampling occasion must be greater than 60% saturation and not the result of a regional event as indicated by similar reductions in DO at the Reference Sites; or, (iii) Median bottom water DO at any site over a four month period must be greater than 60% saturation Oceanica: Marine Produce Australia: Cone Bay Barramundi Aquaculture, Environmental Monitoring & Management Plan 25
