Depositional Model Review - Wallace Cove Baseline Assessment Report
Context
The Proponent, Marine Harvest Atlantic Canada (MHAC), has applied to amend an existing finfish aquaculture license in Wallace Cove, Newfoundland and Labrador, which is located on the south coast of Newfoundland in Facheux Bay. The site was previously licensed to Gray Aqua Group Ltd.; the assets of which were bought by MHAC in 2018. The application seeks to expand the area of the site lease. In accordance with the Aquaculture Activities Regulations (AAR), MHAC has submitted a Baseline Assessment Report which includes predictive modelling of the dispersal of waste from site operations including the predicted contours of biological oxygen demand (BOD) at peak biomass. MHAC used DEPOMOD v2.2 (Cromey et al. 2000, 2002) to predict the effects on the benthos in the proposed expansion area.
On November 5, 2018, the Regional Aquaculture Management Office of the Ecosystems Management Branch in the Newfoundland and Labrador Region requested that DFO Science undertake a review of the Wallace Cove Baseline Assessment Report to determine if the DEPOMOD v2.2 model output is supported by current relevant scientific knowledge of local oceanographic conditions and nature of the substances that may be released at the site. Science Branch undertook a Science Response Process (SRP) for this review. The information from this scientific review will be provided to Ecosystems Management to help form part of the Department's contribution to the provincial siting decision for this site. This Science Response Report results from the Regional Science Response Process of November 16, 2018 on the Depositional Model Validation - Wallace Cove Baseline Assessment Report.
