This No Net Loss Plan documents fish and fish habitat impacts from BHP Billiton's proposed development of three kimberlite pipes (Sable, Pigeon, and Beartooth) at the Ekati Diamond Mine in the Northwest Territories, and outlines habitat compensation strategies to comply with the federal Fisheries Act and DFO's No Net Loss policy.
This information note outlines the environmental assessment process established by the Mackenzie Valley Environmental Impact Review Board under the Mackenzie Valley Resource Management Act, detailing major steps from notification through EA decision and written reasons. The document explains how the Review Board determines scope, manages consultation, conducts technical analysis, and ultimately determines whether development can proceed with or without restrictions, or requires further review.
Draft procedural rules for the Mackenzie Valley Environmental Impact Review Board governing environmental assessment and environmental impact review proceedings under the Mackenzie Valley Resource Management Act. The rules establish protocols for notice, participation, information disclosure, hearings, and Board decision-making.
BHP Billiton Diamonds Inc. submits habitat unit calculations for Leslie Lake to the Department of Fisheries and Oceans in support of a Fisheries Authorization Application for the Sable, Pigeon, and Beartooth Kimberlite Pipes. The document provides baseline fisheries data, habitat zone mapping, and weighted habitat unit calculations for three target fish species (Arctic grayling, lake trout, and round whitefish) based on 1994 survey data.
This draft scope of work outlines the re-evaluation and refinement of the Aquatic Effects Monitoring Program (AEMP) and Panda Diversion Channel Monitoring Program (PDCMP) at Ekati Diamond Mine, detailing specific issues to be evaluated (sampling locations, frequencies, parameters, QA/QC procedures) and proposed analytical methodologies to improve monitoring programs for 2003-2007 field seasons.
BHP Billiton Diamonds Inc. requests a Section 35(2) Fisheries Authorization from the Department of Fisheries and Oceans for the proposed expansion of the Ekati Mine to include development of the Sable, Pigeon, and Beartooth kimberlite pipes, exercising its substitution right under the 1996 Fish Habitat Compensation Agreement by removing Leslie Lake from the development plan and offsetting habitat impacts through the proposed developments.
East Desperation Pond Cofferdam As-Built Construction Report for the Ekati Diamond Mine (BHP Billiton Diamonds Inc., Project No. 0101-94-11580.058), July 2002, prepared by EBA Engineering Consultants Ltd. Includes the As-Built Construction Drawings package (Drawing Index: 11580.058-DPAB01 General Location and Misery Site Plan), UTM Coordinates (NAD 83), East Cofferdam construction sequence (GCL Liner placement at elevations 5.10 / 2.95 / 2.15 / 0.75 m), and loading-ramp configuration for front-end-loader external-feed hopper with Grizzly conveyor.
Geotechnical site investigation report for the proposed Bearclaw Diversion Dam at the Ekati Diamond Mine, documenting subsurface conditions from eight boreholes drilled in April 2002 to support the development of the Beartooth kimberlite pipe. The investigation characterized till overburden (0.3–5.8 m thick) overlying granite bedrock, ground temperature regimes indicating warm permafrost, and bedrock joint characteristics for dam design.
This as-built construction report documents the monitoring and completion of the Waste Rock Dam and Seepage Collection Dam at the Ekati Diamond Mine's Misery site from November 2001 to May 2002, detailing foundation preparation, material placement, liner system installation, thermosyphon construction, and quality assurance testing.
This technical design report describes a prototype surplus water atomization system for the Ekati Diamond Mine's Misery Pit development, designed to treat approximately 400,000 m³ of water annually through atmospheric dispersion and land treatment to reduce ammonia and nitrate concentrations before discharge to Cujo Lake. The system combines air stripping with tundra infiltration and biological treatment by existing microbial communities to complement traditional sedimentation pond methods and mitigate risks of exceeding water licence criteria.
A compilation index of environmental assessment documents and correspondence related to diamond mining projects (DeBeers Snap Lake, Diavik) and other mining developments in northern Canada, including regulatory framework documents, technical reports, and consultation records spanning 1996–2002.
This conference paper describes BHP Billiton's Ekati Diamond Mine in the Northwest Territories and its contribution to sustainable development through integrated environmental, economic, and social management. The document outlines the Environmental Agreement, Socio-economic Agreement, and Impact Benefits Agreements established with governments and Aboriginal groups, as well as environmental management practices and monitoring programs.
The West Kitikmeot / Slave Study Society transmits its Final State of Knowledge Report on the West Kitikmeot / Slave Study area to the Independent Environmental Monitoring Agency, presenting a comprehensive 400-page compilation of published information on the mineral-rich region from Great Slave Lake to the Arctic coast, including geological, ecological, and socioeconomic data updated with over 300 new references.
Public hearing conducted by the Mackenzie Valley Land and Water Board on April 4-5, 2002, to consider BHP Billiton's applications for water licenses and land use permits for expansion of mining activities at the Ekati Diamond Mine, specifically for development of the Sable, Pigeon, and Beartooth kimberlite pipes. The hearing included presentations from BHP Billiton on dewatering, construction, water management, waste rock handling, and reclamation plans, with testimony from engineering and environmental specialists.
Tony Pearse presents the Independent Environmental Monitoring Agency's oral submission to the Mackenzie Valley Land and Water Board regarding BHP-Billiton's water licence and land-use permit applications for the Sable, Pigeon, and Beartooth pipe developments. The presentation highlights deficiencies in application information and proposes recommendations on issues including fish diversion channel design, waste rock seepage control, geochemical characterization sampling adequacy, aquatic effects monitoring, and closure security provisions.
Public hearing transcript from April 4-5, 2002, before the Mackenzie Valley Land and Water Board regarding BHP Billiton's applications for water licenses and land use permits for expansion of mining activities at the Sable, Pigeon, and Beartooth kimberlite pipes at the Ekati Diamond Mine. The hearing presents BHP Billiton's project overview, dewatering plans, construction activities, wastewater management, waste rock management, and reclamation approach, all claimed to use proven methods from existing Ekati operations.
This technical report reviews applicable technologies for managing mining effluents in the Northwest Territories, covering operating and historical mines, regulatory requirements, mining and processing methods, and best available treatment technologies tailored to northern climate and geographic conditions.
