This report documents the results of the 2003 spring waste rock storage area seepage survey at Ekati Diamond Mine, conducted in June 2003 in accordance with Water Licence N7L2-1616 requirements. The survey monitored seepage from five waste rock and kimberlite storage areas, measuring field parameters, flow rates, and conducting laboratory analysis of major ions and dissolved metals.
This as-built construction report documents the construction of the Bearclaw Diversion Dam and associated pipeline civil works at the Ekati Diamond Mine from January to May 2003, detailing design compliance, deviations, construction activities, materials testing, and long-term monitoring procedures for the frozen core dam system.
BHP Billiton's HSEC Report 2003 documents the Ekati Diamond Mine's health, safety, environment, and community performance for the fiscal year July 1, 2002 to June 30, 2003, covering operational metrics, environmental management systems, safety achievements, and community consultation outcomes.
This is an integrated Wastewater and Processed Kimberlite Management Plan for the Ekati Diamond Mine covering two water licences, detailing the management of wastewater sources (lake dewatering, pit water, sewage, site drainage) and processed kimberlite disposal at the Long Lake Containment Facility and other settling ponds over the mine's operational life through 2014.
This environmental review by Golder Associates examines the environmental implications of diamond exploration and mining in Canada, analyzing the growth of the Canadian diamond sector, technical aspects of diamond mining operations, environmental management practices, and regulatory frameworks. The report documents environmental concerns and effects from Canada's operating diamond mines (Ekati and Diavik) and provides recommendations for future policy development regarding diamond mining activities in Canada.
A comprehensive reference and workshop manual for the Department of Fisheries and Oceans outlining considerations for protecting fish and fish habitat in the Northwest Territories during development activities. The manual covers regulatory requirements under the Fisheries Act, habitat components, mitigation strategies for construction near water, and spill response procedures.
This waste rock and ore storage management plan for the Beartooth Pipe at Ekati Diamond Mine addresses regulatory requirements for managing drainage from ore and waste rock storage areas. The plan includes geochemical characterization results, predicted water quality, and monitoring strategies for the proposed mining operation.
BHP Billiton's 2002 Environmental Agreement and Water Licences Annual Report documenting compliance, operations, and environmental monitoring activities at the Ekati Diamond Mine in the Northwest Territories, including mine production from multiple pits, water management, waste handling, reclamation research, and comprehensive environmental monitoring programs for aquatic and terrestrial effects.
This 2002 Environmental Agreement and Water Licences Annual Report from BHP Billiton Diamonds Inc. documents the sixth year of operations at the Ekati Diamond Mine under the Environmental Agreement and four water licences, detailing compliance monitoring, environmental programs, construction activities, and continuous improvement initiatives across water management, waste management, wildlife monitoring, and reclamation efforts.
BHP Billiton Diamonds Inc.'s 2002 Environmental Agreement and Water Licences Annual Report documents the Ekati Diamond Mine's environmental performance and compliance for the sixth year of operation under the Environmental Agreement signed with the GNWT and Government of Canada. The report covers mining operations at multiple pits, water management, processed kimberlite containment, reclamation research, environmental monitoring programs, and continuous improvement initiatives including ISO 14001 certification efforts.
This 2002 waste rock storage area seepage and waste rock survey report for Ekati Diamond Mine documents monitoring of seepage quality, waste rock geochemistry, and thermal conditions at storage areas including Panda/Koala, Misery, and the Coarse Kimberlite Reject Storage Area. The report fulfills Water Licence N7L2-1616 requirements and includes detailed investigations of low pH waters observed since 1999, with findings on sulphate concentrations, acid generation potential, and freeze-concentration effects in seepage.
This is the Environmental Agreement and Water Licences Annual Report for 2002 from BHP Billiton Diamonds Inc. for the Ekati Diamond Mine, covering six years of operations under the Environmental Agreement and reporting compliance with four water licences issued by the Mackenzie Valley Land and Water Board. The report details mining operations, infrastructure development, environmental monitoring programs, waste management, reclamation activities, and compliance with water and environmental regulatory requirements for the year 2002.
This final report describes a comprehensive study of the lethal and sublethal effects of total dissolved solids (TDS) on salmonid embryos and juveniles, including acute and chronic exposure bioassays across multiple species (coho, chum, king, pink, steelhead salmon, and arctic char). The research found that fertilization was the most sensitive developmental stage to TDS exposure, with significant effects observed at concentrations as low as 250 ppm, and that different salmonid species exhibited varying sensitivities to TDS.
BHP Billiton's re-evaluation and refinement report proposes modifications to the Aquatic Effects Monitoring Program (AEMP) for 2003-2007, evaluating sampling locations, monitoring frequencies, and analytical approaches based on historical data analysis and stakeholder consultation. The report recommends adding Leslie Lake to monitoring, continuing triennial monitoring of Little Lake, retaining Vulture Lake as a reference site, and refining seasonal sampling protocols for phytoplankton and zooplankton.
This Acid/Alkaline Rock Drainage and Geochemical Characterization Plan for the Beartooth Pipe at Ekati Diamond Mine describes predictive testing, operational monitoring, and waste rock management strategies to assess potential environmental impacts from mining waste rock storage. Geochemical testing indicates that biotite granite (>99% of waste rock) has low reactivity, while biotite schist and kimberlite require segregation and encapsulation strategies to prevent acid generation and control drainage chemistry.
Tailings Management Binder 2 (2002-2008) for the Ekati Diamond Mine (BHP Billiton). Correspondence between Eric Denholm (BHPB), Sarah Baines (WLWB), Kathleen Racher (DIAND), Tony Pearse (IEMA / Agency), Jim Millard (Environmental Specialist BHP), John Witteman (Environmental Manager BHP), Violet Camsell-Blondin (WLWB Chair). Includes BHPB comments on LLCF water quality model reviews, Wastewater and Processed Kimberlite Management Plan (WPKMP) Conformity Table for Water Licence N7L2-1616 (Section F.1.a.i comprehensive source description), interim water quality objective for chloride from Tier I Ecological Risk Assessment, calcium chloride questions, and kimberlite-and-silicosis discussion.
This document presents the Acid/Alkaline Rock Drainage (ARD) and Geochemical Characterization Plan for the Pigeon Pipe at the Ekati Diamond Mine, prepared by SRK Consulting for BHP Billiton Diamonds to meet Water License MV2001L2-0008 conditions. The plan describes geochemical testing results, waste rock management strategies, and monitoring protocols for host rocks (biotite granite, diabase, biotite schist) and kimberlite, incorporating adaptive management based on operational experience from the Panda and Misery pipes.
This is an Aquatic Effects Monitoring Program (AEMP) re-evaluation and refinement report for 2003-2007 prepared by BHP Billiton and Rescan Environmental Services. The document evaluates and proposes refinements to the AEMP monitoring program for the Ekati Diamond Mine, including assessment of sampling locations, monitoring frequencies, quality assurance procedures, and monitored parameters based on analysis of historical data and comparison with other established monitoring programs.
