BMT WBM (BMT) has completed an independent environmental review of the proposed Woodlark Island Gold Project, situated in the maritime province of Milne Bay in Papua New Guinea.
A subsidiary of BMT Group Ltd, BMT provided an expert review of the Environmental Impact Statement (EIS) and Environmental Management and Monitoring Plan (EMMP) for the mining project.
BMT was commissioned by the Papua New Guinea Department of Environment and Conservation (DEC) to provide technical review, advice and recommendations, which were then incorporated into the final EIS Assessment Report for the Director of Environment to present to the Environment Council.
BMT’s scope of work included a detailed technical review of the EIS and EMMP documentation and development of a numerical model to analyse the predictions made in the EIS regarding the behaviour of tailings from the Deep Sea Tailings Placement (DSTP) in the receiving environment.
According to Lyn Leger, Senior Environmental Consultant at BMT WBM, the review included independent modelling based on Computational Fluid Dynamics (CFD) and Discrete Element Modelling (DEM) software to predict the behaviour of DSTP plumes and provide a basis for cross-checking the impact predictions generated by the modelling outlined in the EIS.
BMT WBM’s work also included a thorough review of the sedimentation impacts in downstream waterways from mining activities such as construction and operation of the mining voids. BMT WBM’s sister company, BMT Cordah provided support in assessing potential social impacts related to food, water and cultural resources and helping to determine whether or not the local people’s livelihoods would be affected by the associated environmental impacts.
Dr Darren Richardson, Project Director at BMT WBM adds that the Environment Council has since provided approval for this project based on the BMT team’s thorough, independent review.
