Transcript of questions and responses from the June 15-18, 2006 Environmental Impact Report Information Session at Ekati Diamond Mine, where BHP Billiton representatives and consultants addressed community and government concerns regarding mining operations, environmental management, wildlife impacts, water quality, waste disposal, and closure planning.
Independent Environmental Monitoring Agency (IEMA) Ekati Closure and Reclamation Workshop, IEMA Boardroom, February 14-16 2006 — workshop agenda, materials and Draft NWT Mine Site Reclamation Guidelines. Sessions cover Mine Component 1 and 2 objectives, options and criteria for further development of Agency advice to BHPB. Includes Mackenzie Valley Land and Water Board (MVLWB) standard licence template Surveillance Network Program text, closure-and-reclamation plan revision/approval timing (six months after Board notification), and reclamation guidance for Aboriginal/Federal/Territorial governments, land owners, communities, regulatory authorities and mining proponents.
Independent Environmental Monitoring Agency (IEMA) Ekati Closure and Reclamation Workshop, February 14-16 2006 — companion/second-set binder. Includes Draft Mine Site Reclamation Guidelines for the NWT (Preface — origins in NWT Water Board and DIAND practice from the early 1980s, complementing the 2002 Mine Site Reclamation Policy), reclamation objectives ensuring abandoned mine facilities are physically stable and require no long-term maintenance, and the Dispute Resolution Article XIV procedures (and Ministerial discretion exception).
This final risk assessment evaluates potential health risks to wildlife and humans from exposure to metals in processed kimberlite at the EKATI Diamond Mine's Long Lake Containment Facility, where vegetation cover is proposed as a reclamation option. The assessment identified ten metals of concern and predicted acceptable risks for most wildlife receptors and human consumers of caribou and goose, with the exception of potential unacceptable nickel risks for humans consuming caribou under elevated soil ingestion scenarios.
This document is a comprehensive presentation from a workshop on Mine Waste Management in the North held in Yellowknife, NWT on November 18, 2005, featuring multiple expert presentations covering acidic drainage prediction and prevention, tailings and waste rock management strategies, water treatment options, biological approaches, and mine reclamation principles with emphasis on northern and permafrost-specific conditions.
This Master's thesis evaluates the application of Multiple Accounts Analysis (MAA), a decision analysis-based Structured Decision Process, as a tool for stakeholder consultation regarding tailings management optimization at the Ekati Diamond Mine in the Northwest Territories. The study, based on questionnaires and interviews with process participants, assesses the effectiveness of this innovative approach to multi-stakeholder consultation in the Canadian mining industry and provides recommendations for future application.
Presentation by Geoff Clark of the Kitikmeot Inuit Association describing KIA's security model for incorporating Inuit values and objectives into reclamation planning and cost estimation for mining projects in Nunavut. The model provides a flexible tool for determining reclamation security amounts across mine components with guiding principles of environmental protection, safety, restoration, and no perpetual care.
A comparative legal study examining financial security requirements for hardrock mining in the NWT relative to ten Canadian and U.S. jurisdictions, identifying gaps in the NWT's regime and proposing an ideal security framework with recommendations for legal reform.
A workshop report documenting the Mine Reclamation and Closure Workshop held February 1–3, 2005 in Yellowknife, which brought together government, industry, Aboriginal representatives, and regulators to discuss mine closure and reclamation objectives, terminology, best practices, and the integration of Traditional Knowledge in mine site remediation planning for northern Canada.
This discussion paper compares mine reclamation and financial assurance legislation across Canadian federal departments, agencies, and provincial governments, with particular focus on the Northwest Territories. It provides an overview of types and amounts of financial assurance required for mining operations and advanced mineral exploration, utilizing the RECLAIM cost estimation model to support government policy on environmental protection and liability management.
This IEMA workshop presentation reviews BHPB's management review of the Long Lake Containment Facility, documenting consultation processes with regulators and communities on processed kimberlite containment options and cell-filling challenges at the Ekati Diamond Mine.
This IEMA workshop presentation reviews environmental monitoring and management programs at the Ekati Diamond Mine for 2004, covering mining operations, water licence renewal, LLCF management changes, closure planning challenges, and wolverine incidents.
This 2004 annual report documents the operational activities and management of the Contaminated Snow Containment Facility (CSCF) at Ekati Diamond Mine, including ice transfer, facility inspections, water sampling results, and removal of hydrocarbon-impacted water and debris. The facility successfully contained approximately 422 m³ of hydrocarbon-impacted ice and managed 234.5 m³ of contaminated water disposal during the 2004 operational season.
This 2004 annual report presents a five-year assessment of revegetation research at the EKATI Diamond Mine's Long Lake Containment Facility, documenting soil amendment studies, species trials, and plant establishment on processed kimberlite, along with evaluation of progressive reclamation sites including airstrip esker, topsoil stockpiles, and channel stabilization efforts.
Minutes from the Ekati Long Lake Containment Facility (LLCF) Review and Optimization Meeting #3 (February 7-8, 2005), documenting a Multiple Accounts Analysis (MAA) evaluation process and detailed lessons learned from five years of LLCF operation, including operational, hydrological, reclamation, and wildlife habitat findings. The meeting reviewed five management options for processed kimberlite disposal and closure strategies.
An ICMM-commissioned study examining environmental financial assurance (EFA) instruments and policies for mine closure and reclamation globally, providing framework and negotiation guidelines for governments and mining companies to balance environmental protection with investment climate and cost efficiency.
A bilingual English-Chipewyan glossary of technical and environmental terms related to mine operations, soil science, reclamation, and landscape development at the Ekati Diamond Mine, including regulatory agencies and environmental management concepts.
This technical report assesses scientific and management information needs for consistent decisions on fish habitat management in northern Canada regarding diamond, oil sands, and placer mining operations. It reviews the biology and ecology of seven Arctic fish species, examines watershed-level cumulative effects, and identifies critical deficiencies in knowledge about compensatory and restorative measures for habitat destruction, particularly the elimination of lakes for mining activities.
This technical report examines fish habitat management in northern Canada with focus on diamond, oil sands, and placer mining operations, identifying critical knowledge gaps and policy considerations needed to comply with the Fisheries Act and achieve 'no net loss' of fish habitat productive capacity. The report documents that 70 lakes have been or are proposed to be eliminated for mining use since the 1950s, with 62% approved in the last decade, and recommends integrated research, monitoring, and collaborative management approaches to address deficiencies in Arctic aquatic ecology understanding.
Closure and Reclamation Binder 2 for the Ekati Diamond Mine — Wek'èezhii Land and Water Board (WLWB) and BHP Billiton correspondence (2007-2008).
