Sample percentiles (median and 95th) will be calculated twice: once, after each sampling occasion and then again, following the completion of the four month sampling period. After each sampling occasion For sites positioned at the HEPA and MaxEPA boundaries: ammonia and DO values obtained from the sites at the boundary of the respective ecological protection areas will be pooled and the sample median calculated (n=4). For gradient sites, the following protocol shall be used: � Where sea-cages are positioned greater than 200 m from the western MEPA/HEPA boundary (such that all sites are positioned in the MEPA, irrespective of current direction), the median shall be calculated from pooled values obtained across individual sites (0 m-200 m) (n=5) and compared against the EQG for moderate protection. � Where sea-cages are positioned less than (or equal to) 200 m from the western MEPA/HEPA boundary (meaning some or all of the sites are inferred to be in the HEPA), medians shall be calculated separately e.g. MEPA - 0 m, 10 m and 50 m (n=3) and HEPA - 100 m and 200 m (n=2). MEPA and HEPA site medians shall be compared with the EQG for moderate and high protection, respectively. 38 Oceanica: Marine Produce Australia: Cone Bay Barramundi Aquaculture, Environmental Monitoring & Management Plan Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Proceed�to�EQS�for� moderate��protection Proceed�to�EQS�for� high�protection Proceed�to�EQS�for� moderate�protection Proceed�to�EQS�for� high�protection Proceed�to�EQS�for� moderate�protection Proceed�to�EQS�for� high�protection Proceed�to�EQS�for� moderate�protection Proceed�to�EQS�for� high�protection Proceed�to�EQS�for� moderate�protection Proceed�to�EQS�for� high�protection
� Where sites are inferred to be in the MEPA and the HEPA, as in the above example, medians should not be calculated if the number of sites is less than n=3 (as a minimum of three samples is required to derive a meaningful estimate). In this case, additional samples shall be obtained such that the number of measurements is at least n=3 (see also footnote #15). Median DO values will be compared to the EQG calculated from n=8 Reference Sites. EQG, encompassing the 80th and 90th percentiles shall be calculated after each sampling occasion. After completion of the four month sampling period At the completion of the four month sampling period, ammonia and DO values obtained at each of the HEPA and MaxEPA sites over the four sampling occasions will be pooled and the sample percentiles calculated. For example, the median for high protection site 1 (H1) will be calculated by pooling data obtained on sampling occasions 1, 2, 3 and 4.. Similarly, at the completion of each sampling occasion, ammonia and DO values obtained in the MEPA, or any gradient site located outside of the MEPA, will also be pooled and the sample median calculated: Where sea-cages are located greater than 200 m from the western MEPA/HEPA boundary (such that all sites are positioned in the MEPA, irrespective of current direction), medians will be calculated by pooling data obtained on occasions 1, 2, 3 and 4, and compared against the EQG for moderate protection. However, where sea-cages are located less than (or equal to) 200 m from the western MEPA/HEPA boundary (meaning some or all of the sites are inferred to be in the HEPA), the EQG will be assessed differently depending on the inferred position of the sites. For example, if a site falls outside the MEPA, then the EQG for high protection will be used, and if the site falls within the MEPA, then the EQG for moderate protection will be used. This approach is summarised in Figure 5.1. For sites positioned at the HEPA and MaxEPA boundaries, sample percentiles will be calculated for each of the replicate sites (n=4): H1-H4 and Max1-Max4, respectively. Median DO values will be compared to the relevant EQG calculated from pooled Reference Site data (n=4x8=32) obtained over the four month sampling period. In the event the EQG for ammonia is exceeded, spare samples collected on the same day as the original samples will be analysed. If the EQG is still exceeded following reanalyses, then monitoring shall be undertaken against the relevant EQS as soon as reasonably practicable. 5.1.3 Chlorophyll-a Sample medians will be calculated after each sampling occasion. Chlorophyll-a values obtained from the sites at the boundary of the HEPA will be pooled and the sample median calculated (n=4). In this case, the sample median will be compared against the EQF for high protection (80th percentile). Identical methods will be employed in the case of the MaxEPA: Chlorophyll-a values obtained from the sites at the boundary of the MaxEPA will be pooled and the sample median calculated (n=4). In this case, the sample median will be compared against the EQF for maximum protection (70th percentile). These data will be compared to the EQG calculated from n=8 Reference Sites. EQG should be calculated after each sampling occasion. In the event the EQG is exceeded, spare samples collected on the same day as the original samples will be analysed. If the EQG is still exceeded following reanalyses, then monitoring shall be undertaken against the relevant EQS as soon as reasonably practicable. 5.1.4 Sediment quality Sample percentiles (median and 95th) will be calculated twice: once, after each sampling occasion and then again, following the completion of the four month sampling period. After each sampling occasion At the completion of each sampling occasion, TKN, TP, TOC and redox discontinuity values obtained at the HEPA and MaxEPA boundaries respectively will be pooled and the sample median calculated (n=4). Similarly, at the completion of each sampling occasion, TKN, TP, TOC and redox discontinuity values obtained at gradient sites will also be pooled and the Oceanica: Marine Produce Australia: Cone Bay Barramundi Aquaculture, Environmental Monitoring & Management Plan 39
