EXECUTIVE SUMMARY METROPOLITAN COAL PROJECT INDEPENDENT ENVIRONMENTAL AUDIT The Independent Environmental Audit for compliance with Project Approval 08_0149 and other environmental approvals for the Metropolitan Coal Project was carried out during December 2011 and February 2012, by a team of experienced and independent experts endorsed by the Director-General. The audit review, assessment of the documentation and performance of the Metropolitan Coal operations demonstrated a high degree of compliance with the Project Approval and other environmental approvals granted for the project. Air Quality Dust management at the Metropolitan Colliery surface facilities area is managed in a satisfactory manner with monitoring results demonstrating compliance with the Project Approval and EPL criteria. Blasting No blasting activities have occurred on the surface operational areas of Metropolitan Coal leases. Biodiversity To date no impacts on threatened species, populations or ecological communities have been recorded from the various monitoring programs. The location for majority of monitoring sites is considered adequate but some suggestions are provided to improve the ongoing monitoring. Monitoring of environmental values that are likely to represent important habitat for threatened species, populations or ecological communities have been undertaken within the study area (including surface water quality and flow, cliffs, steep slopes, upland swamp groundwater etc.). Short term effects observed in some of parameters are attributable to natural variation as the changes have been observed in both control and potential impact sites. Erosion and Sediment Control The procedures that have been developed within the management plans provide a sound basis for erosion and sediment control for surface activities conducted by Metropolitan Coal. Groundwater The project is compliant with the conditions relating to groundwater management. None of the performance measures or performance limits relating to groundwater were exceeded during the 2010- 2011 period. Subsidence Based on the review of the Extraction Plan, AEMR documents for 2010 and 2011, and the End of Panel Report for LW20, Metropolitan Coal has complied with the Project Approval conditions for mine subsidence impact management during the audit period. Surface Water The surface water quality discharges to Camp Creek were compliant with the EPL criteria during 2010-2011 except for one TSS and one pH excursion (January 2010 and August 2010 respectively). Rehabilitation The rehabilitation strategy and rehabilitation monitoring program for proposed works is considered appropriate for long term management of the Metropolitan Coal mining activities. 6 trevor brown & associates applied environmental management consultants aemc
