This conference paper explains adaptive management as a rigorous approach to environmental management that explicitly addresses uncertainty through designed experiments, monitoring, and iterative learning, with three case studies demonstrating application to habitat restoration in the Columbia River Basin, ecosystem restoration in the Trinity River in California, and invasive species management in Garry oak ecosystems in British Columbia.
BHP Billiton Diamonds Inc. 2004 Waste Rock Storage Area Seepage Survey "Book #17" — transmittal August 13 2004 to Stephen Neilsen, Interim Chair, Mackenzie Valley Land and Water Board. File 4.6.6.1 / 5.6.11.2. Includes Appendix A.3 Panda/Koala Southwest Detailed Seepage Results (Total Chloride, Bromide, Fluoride, Electrical Conductivity, Hardness, Sulphate SO4-LO, Total Dissolved Solids TDS) at SEEP-027 station from 2001-2003 sampling and Stallion station data with QA/QC detection-limit minus-flagged values.
Environment Canada responds to EMAB recommendations on water quality monitoring at Lac de Gras, explaining the application of national water quality guidelines to site-specific conditions and the process for developing site-specific water quality objectives considering local limnological factors and aquatic communities.
EMAB proposes that IEMA and EMAB jointly send a letter to DIAND requesting that DIAND convene a workshop on cumulative effects of diamond mining on wildlife, rather than IEMA and EMAB pursuing the workshop independently.
Hearing transcript from the Mackenzie Valley Land and Water Board on July 6, 2004, regarding BHP Billiton Diamonds Inc.'s application for renewal of water license MV2003L2-0013 for the Ekati Diamond Mine in the Northwest Territories. The hearing covers the mine's operational history, environmental performance, employment initiatives, and discussion of license renewal terms including effluent standards, license duration, security requirements, and engineering oversight procedures.
MV2003L2-0013 Public Hearing Binder for Renewal of Ekati Water Licence N7L2-1616, July 6-7 2004, compiled by the Independent Environmental Monitoring Agency for the Mackenzie Valley Land and Water Board (MVLWB Yellowknife). Key issues: Precautionary Principle, Effluent Discharge Limits, Abandonment & Restoration Plan, Waste Rock Seepage. Includes BHP Billiton Diamonds Inc. (BBDI) discussion of Discharge Criteria and predicted downstream AEMP increases in pH, sulphate, TDS, potassium, nitrate, nitrite, molybdenum and chloride. Appendix II Supporting Documents: Rescan Sept 2003 "Comparative Study: EIS Predictions versus Actual", 2001 Fox Waste Rock and Ore Storage Management Plan Addendum #1 (Approved by MVLWB August 2003), 2000 Spill records.
BHP Billiton's 2004 Health, Safety, Environment and Community (HSEC) Summary Report presents the company's sustainability performance for the fiscal year ending 30 June 2004, including goals for zero harm, environmental management targets, community contributions, and recognition of 17 workplace fatalities as a major concern requiring strengthened safety protocols. The report details performance across health, safety, environmental, community, and socio-economic dimensions, with emphasis on implementing fatal risk control protocols and achieving sustainable development across global operations.
Laboratory toxicity study examining acute and chronic effects of nitrate exposure on early life stages (embryos, alevins, swim-up fry) of lake whitefish and lake trout collected from the Ekati Diamond Mine region and Lake Simcoe, Ontario. The study determined NOECs, LOECs, and LC50 values for nitrate and found that lake whitefish were more sensitive to chronic nitrate exposure than lake trout, with early developmental stages showing sublethal effects at concentrations as low as 6.25–25 mg/L NO3-N.
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 study evaluates the potential effects on fish habitat of extracting an additional 50,000 m³/year of water from Grizzly Lake at the EKATI Diamond Mine, using a mass balance model under various climatic scenarios. The analysis concludes that while increased extraction could cause significant degradation of summer fish habitat in Grizzly Stream under extreme dry conditions, practical effects would be negligible due to the stream's already poor habitat quality, and impacts to the Panda Diversion Channel and Grizzly Lake itself would be minimal.
This report presents a downstream dilution study of effluent discharged from the Long Lake Containment Facility (LLCF) into a chain of lakes leading to Lac de Gras. A mass balance dilution model was developed, calibrated against historical water quality data from 1997-2003, and used to predict water quality compliance with CCME guidelines and proposed water licence criteria for 2004-2015.
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.
Matthews Lake and Area Fish Habitat Restoration Program — 2003 Site Baseline Assessment, April 2004, prepared by Dillon Consulting Limited for the Department of Fisheries and Oceans (DFO Fish Habitat Management, Yellowknife) and submitted to Carole Mills (Independent Environmental Monitoring Agency), File 03-1851-2000. Documents the November 2003 Pre-Construction Workshop with regulatory agencies and stakeholders, references aquatic habitat assessment methodology (Bain & Stevenson 1999), stream dimensions at road crossings (7 m wide / 10 m long / 0.1 m avg depth, 0.03 m/s velocity, 10% fine / 50% gravel / 30% cobble / 10% boulder substrate), and excavation plans for connecting Sandy Lake to Ponds A, B, C and Matthews Lake.
BHP Billiton's 2004 annual report covering 2003 operations and environmental compliance at the Ekati Diamond Mine in the Northwest Territories, detailing monitoring programs for water quality, air quality, wildlife populations, and reclamation efforts under the Environmental Agreement and five Water Licences.
The Mackenzie Valley Resource Management Act (2004) establishes an integrated system of land and water management in the Northwest Territories, creating land use planning boards, land and water boards, and an environmental impact review board to regulate resource use in settlement areas of the Gwich'in, Sahtu, and Tlicho First Nations in accordance with their comprehensive land claim agreements.
Anne Gunn from GNWT Wildlife and Fisheries provides comments on the 2003 Ekati Diamond Mine Wildlife Effects Monitoring Program, analyzing caribou monitoring data from 1987-2003 and addressing habitat loss, behavioral responses to mining, atmospheric contamination, and processed kimberlite tailings risks to wildlife. The document recommends adaptive monitoring and mitigation strategies to address cumulative effects on the declining Bathurst caribou herd.
This workshop presentation documents the 7th year findings of the Wildlife Effects Monitoring Program (WEMP) at Ekati Diamond Mine, covering 2003 field season results for caribou, grizzly bears, wolves, wolverines, and birds, with assessment of habitat losses, wildlife incidents, and recommendations for monitoring improvements.
