The Joint Review Panel provides guidance for Topic-Specific General Hearings scheduled for March 2007 in Inuvik and Yellowknife concerning environmental and socio-economic management plans, monitoring programs, and follow-up procedures for the Mackenzie Gas Project. The document outlines hearing topics, key discussion matters, and procedural questions to guide participant preparation.
This document is the draft Interim Closure and Reclamation Plan (ICRP) for the Ekati Diamond Mine, prepared by BHP Billiton in January 2007, providing comprehensive closure objectives, reclamation criteria, research plans, and monitoring protocols for all major mine components including open pits, underground mines, waste rock storage areas, and containment facilities.
This interim closure and reclamation plan for the Ekati Diamond Mine outlines BHP Billiton's objectives, methods, and timeline for closing and reclaiming the mine site, with operations anticipated to continue until 2020 and post-closure monitoring extending to approximately 2054. The plan addresses six major mine components—open pits, underground mines, waste rock storage areas, processed kimberlite containment facilities, dams/dykes/channels, and buildings/infrastructure—detailing pre-disturbance conditions, closure criteria, engineering approaches, risks, research needs, and monitoring programs.
Letter from Joint Review Panel for the Mackenzie Gas Project (Inuvik, NT) to Dr. Bill Ross, Chair, Independent Environmental Monitoring Agency for the Ekati Diamond Mine, January–February 2007. Invites IEMA participation in the JRP hearing on the proposed Mackenzie Gas Project — focused on decommissioning and abandonment of pipeline infrastructure (including transfers), effectiveness of existing socio-economic and biophysical environmental monitoring and follow-up regimes in the NWT, and regulatory bodies' inspection/enforcement of Ekati licenses and permits. Panel Manager: Paula Pacholek.
This detailed design report for the Pigeon Stream Diversion at the Ekati Diamond Mine describes a 430-meter engineered channel to route Pigeon Stream around the proposed open pit development, maintaining fish passage and seasonal habitat compensation with thermal stability over 3-5 years. The design includes three sections (inlet, routing, outlet pool), a geomembrane liner system, and construction specifications for winter implementation.
This report proposes a site-specific chloride discharge criterion of 1,332 mg/L for discharges from Two Rock Sedimentation Pond related to potential Sable kimberlite pipe mining operations at EKATI Diamond Mine, based on toxicological testing establishing an aquatic threshold (HC5) of 313 mg/L and hydrodynamic modelling demonstrating a dilution factor of 4.26 in Horseshoe Lake over 21-day periods.
BHP Billiton's 2006 Annual Report on Northern Employment and Spending for the Ekati Diamond Mine operations phase documents that the mine created 1,034 person-years of direct employment and purchased $326 million in goods and services from northern businesses, both exceeding Socio-Economic Agreement targets.
The Mackenzie Valley Environmental Impact Review Board announces that former members Danny Bayha and Bernadette Stewart have withdrawn from reappointment consideration due to delays in the federal appointment process, creating concerns about the Board's ability to maintain quorum and conduct environmental impact assessments.
This document is a comprehensive presentation and tour package for the Ekati Diamond Mine closure options evaluation conducted July 7-9, 2006, involving community representatives, regulators, and IEMA. It details closure options for major mine components (open pits, waste rock storage areas, the Panda Diversion Channel, and Long Lake Containment Facility), technical information on mining operations, and BHP Billiton's environmental and social commitments.
This document contains transcribed dialogue and written responses from the Ekati Diamond Mine Environmental Impact Report Information Session held June 15–18, 2006, in which BHP Billiton, government agencies, Indigenous representatives, and consultants addressed questions on mining operations, waste management, environmental monitoring, wildlife impacts, closure planning, and regulatory compliance.
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.
The Mackenzie Valley Environmental Impact Review Board releases a 2006 Socio-Economic Impact Assessment Workshop Report and announces a public comment period ending June 30, 2006 for Draft SEIA Guidelines developed to improve environmental assessment practices in the region.
This 2005 annual report documents the Caribou and Roads Traditional Knowledge Project at the Ekati Diamond Mine, describing how an Elders Advisory Group from Kugluktuk integrates traditional Inuit knowledge with scientific monitoring to manage caribou-infrastructure conflicts. The report presents findings from an August 2005 site visit and a January 2006 workshop, including recommendations for using inokhok (traditional stone cairns) and other deterrents to guide caribou away from hazardous mine areas.
This 2005 Ekati Diamond Mine caribou and wildlife monitoring report, prepared in Inuinnactun by Rescan Environmental Consulting and community monitors from Kugluktuk, documents observations of caribou movements, habitat conditions, and environmental impacts around the mine site based on Indigenous knowledge and field surveys.
A two-day technical workshop held April 11-12, 2006 in Yellowknife to develop guidelines and best practices for aquatic effects monitoring and assessment of development projects in the NWT, including baseline data collection, limnological assessments, and monitoring programs for mining and other industrial activities.
The EKATI Diamond Mine Environmental Impact Report 2006 compares environmental monitoring results from 2003-2005 with predictions from the 1995 Environmental Impact Statement, finding that over 90% of residual effects were positive, negligible, or minor, though noting increasing ion and nutrient concentrations downstream of the Long Lake Containment Facility and a moderate alteration of caribou distribution relative to the mine footprint.
This document comprises the appendices to the 2005 Wildlife Effects Monitoring Program (WEMP) report for the Ekati Diamond Mine, containing standard operating procedures for wildlife monitoring activities, data collection forms, and detailed survey results for caribou, grizzly bears, wolves, wolverines, and birds.
