It covers diamond discovery, production, processing, marketing, community relations, and environmental monitoring programs across multiple pit mines and underground operations.
This technical report presents findings from the 2002 Panda Diversion Channel (PDC) Monitoring Program at the Ekati Diamond Mine, documenting hydrology, fish communities, habitat stability, and benthic and periphyton communities in the channel designed to compensate for habitat lost to mining operations. The 2002 monitoring year was characterized by low spring precipitation and peak flows, yet Arctic grayling continued to extensively utilize the PDC for spawning and migration with the second-highest numbers recorded since monitoring began in 1998.
The 2002 Aquatic Effects Monitoring Program (AEMP) Data Report presents comprehensive environmental monitoring data collected at the Ekati Diamond Mine, including meteorological, hydrological, water quality, sediment quality, and biological community data (phytoplankton, zooplankton, benthos, and fish) from multiple lakes and streams for the year 2002.
This is Working Draft #4 of a Cumulative Effects Assessment and Management (CEAM) Regional Plan of Action for the Slave Geological Province, prepared by the SGP Project Group under review by federal and territorial governments and multi-stakeholder committees. The document outlines a framework for assessing and managing cumulative environmental effects from mining, infrastructure, and other development activities across the approximately 300,000 km² SGP region spanning NWT and Nunavut, identifying gaps, challenges, and recommended actions across nine CEAM framework components including land use planning, baseline monitoring, research, regulation, and information management.
This comprehensive air quality monitoring report for the Ekati Diamond Mine covers 1998-2001 data, analyzing total suspended particulates, snow chemistry, and emissions from mining operations to assess environmental impacts. The report concludes that air quality objectives appear to be met at mineral claim boundaries, with dust and metal deposition limited to approximately 5 km from mine activities, though gaseous emissions show broader atmospheric distribution.
The 2002 Aquatic Effects Monitoring Program technical report evaluates baseline and post-baseline monitoring data from the Koala and King-Cujo watersheds to assess impacts of the Ekati Diamond Mine on aquatic environments. The report finds that while mine activities caused localized changes in water quality parameters within both watersheds, no major adverse ecological effects were observed in biological communities, though some elevated nutrient levels and phytoplankton biomass changes were detected in specific receiving lakes.
This annual report documents revegetation research and progressive reclamation efforts at the Ekati Diamond Mine in 2002, presenting results from multiple treatment sites including the Panda Diversion Channel, Culvert Camp, and Fred's Channel, with emphasis on plant survival rates, species establishment, and soil conditions supporting future mine closure rehabilitation.
"Towards a Single Regional Monitoring Agency for the Slave Geological Province (SGP)" Workshop — Participant Resource Binder, Explorer Hotel Yellowknife, November 13-14 2002. Includes Steven A. Kennett (Canadian Institute of Resources Law) "Project-Specific Environmental Agreements in the NWT: Review of Issues and Options" prepared for Environment and Conservation DIAND NWT Region, working-draft Workshop Purpose / Objectives / Outcomes for an SGP Regional Monitoring Agency (funding considerations, resource needs, parties' interests and expectations), Day 1 conclusions on Cumulative Effects Coordination + Capacity, Information Provision, long-term commitment / financing, Transboundary Issues, WKSS-precedent partnership, and Legalities; with Chris Hanks (BARB) 3-slide presentation positioning Environmental Agreements as cornerstones (BHP first in 1996, pre-MVRMA) under amended Article 6.
This is the 2002 Wildlife Effects Monitoring Program (WEMP) draft report for the Ekati Diamond Mine, documenting environmental and wildlife monitoring results from 1997-2002. The report comprehensively tracks impacts on valued ecosystem components including caribou, grizzly bears, wolves, wolverines, birds, and other species, with sections on habitat loss, vehicle collisions, landfill attractants, mortalities, and behavioral disturbance patterns.
This report evaluates the toxicity of nitrates to early life stages of salmonid fish, with specific application to wastewater from the Ekati Diamond Mine in the Northwest Territories. The analysis examines the Kincheloe et al. (1979) research indicating nitrate toxicity at concentrations around 10 mg/L and recommends this as a tentative water quality criterion, while noting that Moose Lake currently shows rising but still acceptable nitrate levels.
This AEMP re-evaluation and refinement report for the Ekati Diamond Mine proposes modifications to the aquatic effects monitoring program for 2003-2007, including assessments of sampling locations (Grizzly, Leslie, and Little Lakes), annual and seasonal monitoring frequencies, quality assurance/quality control procedures, and evaluated parameters. The document evaluates whether water quality changes in Grizzly Lake result from fugitive dust or ANFO leaching, recommends adding Leslie Lake and reconsidering Vulture Lake as reference sites, and proposes reducing seasonal phytoplankton and zooplankton sampling from three times per year to August-only collection while maintaining other monitoring frequencies.
Final design report for Bearclaw Diversion Dam at Ekati Diamond Mine, a frozen core rockfill dam designed to divert water from Bearclaw Lake around the proposed Beartooth Pit during open-pit mining. The report presents thermal and stability analyses, construction plans, and monitoring requirements for this high-consequence structure.
Comprehensive literature review documenting the life history characteristics and riverine habitat requirements of 46 freshwater fish species occurring in the Northwest Territories and Nunavut, with detailed habitat preference data organized by species, developmental stage, and physical habitat features including depth, substrate, cover, and water quality.
This is a draft report evaluating and refining the Aquatic Effects Monitoring Program (AEMP) at the Ekati Diamond Mine for the 2003-2007 period. The report recommends modifications to sampling locations (adding Leslie Lake, evaluating Vulture Lake and Little Lake), monitoring frequencies, and analytical procedures based on assessment of historical data and comparison with established monitoring guidelines.
Technical specifications and construction drawings for the installation of three stream crossings (SR-3, SR-4, SR-5) along Sable Road at Ekati Diamond Mine, including detailed requirements for culvert placement, foundation preparation, fill materials, and seepage collar installation.
BHP Billiton's 2001 Environmental Agreement Annual Report documents comprehensive environmental monitoring and management programs at the Ekati Diamond Mine in the Northwest Territories, including air and water quality assessments, wildlife effects monitoring, fish habitat restoration, and progressive reclamation efforts. The report demonstrates the company's commitment to minimizing environmental impacts through adaptive management, traditional knowledge integration with Aboriginal groups, and compliance with regulatory requirements including the Type A Water Licence.
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 technical report synthesizes and analyzes hydrologic, benthic invertebrate, periphyton, and fisheries data collected from the Panda Diversion Channel Monitoring Program from 1998–2001, evaluating the effectiveness of the constructed compensation channel that maintains fish passage between North Panda and Kodiak Lakes at the Ekati Diamond Mine. The report presents streamflow hydrographs, rating curves, habitat assessments, and biological community analyses to support future management decisions for the channel through 2007.
This Master's thesis investigates the establishment of vegetation cover on processed kimberlite mine tailings at the Ekati Diamond Mine in the Northwest Territories through greenhouse and field studies.
