Public hearing binder for BHP Billiton Diamonds Inc.'s water license renewal (MV2003L2-0013) for the Ekati Diamond Mine, held July 6-7, 2004, containing company presentations, interventions from federal and territorial agencies, and monitoring data on environmental performance over six years of operations.
This interim abandonment and reclamation plan for the Ekati Diamond Mine describes the reclamation strategy for seven kimberlite pipes (Panda, Koala, Beartooth, Fox, Misery, Sable, and Pigeon) and associated mine infrastructure, addressing regulatory requirements, environmental management, progressive reclamation during mine operations, and final closure procedures scheduled for 2016.
Workshop report documenting BHPB's environmental monitoring and management programs at Ekati, including a risk assessment of wildlife exposure to processed kimberlite and metals, and a dust monitoring program for plant health. BHPB concluded there is no health risk to animals or people from processed kimberlite exposure.
This document is a final draft comprehensive guideline for best environmental management practices in mining operations across the Northwest Territories, prepared by Gartner Lee Limited for DIAND, covering the complete mine lifecycle from exploration through closure with emphasis on sustainable development principles and northern-specific environmental conditions.
BHP Billiton submission of supporting documents accompanying a revised Wastewater and Processed Kimberlite Management Plan for the Ekati Diamond Mine, including risk assessments, water quality predictions, and fish population surveys.
BHP Billiton's integrated Wastewater and Processed Kimberlite Management Plan for the Ekati Diamond Mine describes wastewater sources (lake dewatering, site drainage, pit water, sewage) and processed kimberlite disposal into the Long Lake Containment Facility and associated sedimentation ponds, with water and solids balance projections over the mine's 18-year operational life under two water licences.
Golder Associates conducted a wildlife and human health risk assessment for BHP Billiton regarding exposure to processed kimberlite at the Long Lake Containment Facility (LLCF) at the Ekati Diamond Mine. The assessment evaluated potential risks to seven wildlife species and humans consuming caribou that may ingest metals from revegetated processed kimberlite, concluding that no unacceptable health risks to wildlife populations or humans would result from the abandonment and reclamation plan.
This comprehensive informational document published by Indian and Northern Affairs Canada describes eleven contaminated sites across the Northwest Territories resulting from past mining and military operations, detailing the contamination issues, ongoing remediation efforts, and future management plans for each site. The document emphasizes the federal government's commitment to cleaning up these sites to protect human health and the environment, and outlines new policies and legislation designed to prevent similar contamination from future industrial activities.
BHP Billiton Diamonds Inc. applies to renew water licence N7L2-1616 for continued operation of the Ekati Diamond Mine from 2004 to 2015, detailing water use, waste management, environmental monitoring, and predicted impacts of mining activities in the Koala watershed near Yellowknife, Northwest Territories.
This 2003 annual report documents four years of revegetation research on processed kimberlite tailings at the EKATI Diamond Mine's Long Lake Containment Facility (LLCF). The studies evaluate soil amendments, seeding strategies, and native plant establishment methods to determine whether vegetative cover is viable for reclaiming the facility instead of the originally proposed rock cover.
"Introduction to Metal Leaching and Acidic Drainage" — course material from a Northwest Community College workshop September 22-26 2003, instructor Bill Price. Covers ML/ARD definitions and mining relevance, material characterization and prediction, limestone-drain treatment of seepage/subsurface drainage (limited by acid and sulphate loading rates, prone to precipitate clogging), contingency planning for prediction uncertainty, site-specific mitigation, cumulative count of major BC mines with identified ML/ARD concerns (1970-1990 historic-closed/recently-closed/operating categories), and acknowledgements to Mike Aziz (Equity Silver), Kim Bellefontaine (BC MEM), Glenda Ferris, Mark Freberg (Highland Valley Copper), Doug Johnson (Huckleberry Mine), Walter Kuit, Bruce Donald (TeckCominco).
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.
Tour Itinerary for the Ekati Diamond Mine Water Licence Renewal site visit (August 28 2003), prepared by BHP Billiton Diamonds Inc. (Yellowknife) and transmitted to Doug Doan. Includes Stop 5 Koala North Underground (first underground diamond mine in Canada — development began February 2002 using overhand cut-and-fill mining method), water-truck logistics for potable water delivery to Misery Camp and Koala North Underground office/shower facilities, process-plant kimberlite-crushing-and-slurry workflow, and Desperation Pond seepage/runoff collection on the west side of the Misery Waste Rock Storage Area (two cofferdams, 8-tower atomization array, 400,000 m³ water capacity with MVLWB-approved baseline studies and monitoring).
EBA Engineering Consultants Ltd. completed the annual water licence geotechnical inspection of seven water control structures at Ekati Diamond Mine between July 6-9, 2003, including Phase I Pond, Panda Diversion Dam, Long Lake Outlet Dam, Intermediate Dyke B, King Pond Dam, Waste Rock Dam, and Desperation Pond Cofferdams, documenting their condition through visual observations, ground temperature data, and settlement monitoring.
This interim abandonment and reclamation plan describes BHP Billiton's strategy for reclaiming disturbed areas at the Ekati Diamond Mine following the mining of seven kimberlite pipes through 2014, detailing reclamation approaches for pit lakes, waste rock storage, processed kimberlite containment facilities, water management structures, and supporting infrastructure to restore stable landforms and wildlife habitat.
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.
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.
