Version Author Authority Comment MPA response Rev3 Rev3 Rev3 Rev3 Rev3 Rev3 Oceanica Oceanica Oceanica Oceanica Oceanica Oceanica OEPA OEPA OEPA OEPA OEPA OEPA MPA Response Section 4.3 and 4.4 for Coral Health and Sediment Infauna respectively provide detailed descriptions of the sampling protocols, including the sampling frequency upon exceedance of an EQG. Section 5.2 outlines the frequency of TSS and LAC monitoring following exceedance of an EQG. MPA Response Agreed. The sediment sampling regime has now been modified such that the EQG is assessed at the completion of each sampling occasion. Re-sampling immediately is also likely to be impracticable given the distance samples must be freighted and laboratory turnaround times. MPA propose to collect duplicate samples only one of which will be analysed initially. The remaining samples will be analysed only upon exceedance of the EQG. MPA response Table 1.4 of the EMMP includes a number of proponent commitments. One of the commitments, to be completed within one year of proposal implementation, is to undertake a risk assessment of the potential for adverse effects to wild fish fauna as a result of the use of vaccinations. MPA response Agreed. See response above for similar comment made with regard to water quality sampling. MPA response Agreed. The revised EMMP includes bottom water total ammonia as an indicator in each of the ecological protection areas, and at the Reference Sites. MPA Response Much thought has been given to the likely cause effect pathways. Following discussions with the OEPA on 18th November 2001, new indicators were introduced including in water measures of TSS and sediment TOC. The program covers both primary and secondary indicators of environmental stress including redox discontinuity, bottom water DO and total ammonia. Table 1.4 of the EMMP includes a list of proponent's commitments. The proponent has committed to a risk assessment to determine (i) whether trace elements contained within aquaculture feeds are accumulating in sediments beneath and/or adjacent to

It is expected that the results of the study will inform the timing and extent of future analyses. Sediment in fauna species richness has been chosen as the key indicator for sediment health. Infauna are sensitive to impacts from sea-cage aquaculture (including organic enrichment, ammonia toxicity, reduced DO etc) and can be correlated with minor to severe levels of degradation. 'Ambient' value has been changed to 'median' value.
