Health Canada's review of BHP's Environmental Impact Statement for a diamond mining project, providing comments on conformity with EIS guidelines and identifying deficiencies regarding radiological hazards, particularly radon gas exposure and the need for baseline radioactivity monitoring in ore and environmental compartments.
Health Canada's review of BHP's Environmental Impact Statement for the Ekati Diamond Mine, identifying conformity with EIS guidelines but noting deficiencies in radiological risk assessment, particularly regarding radon gas exposure and incomplete baseline radioactivity data for ore and natural compartments.
Health Canada reviews BHP's Environmental Impact Statement for the diamond mine project, finding human health information largely conforming to guidelines except for deficiencies regarding radon gas exposure risk assessment. The review requires the proponent to analyze ore and environmental samples for radioactive source terms and establish a radon gas monitoring program to ensure compliance with radiation regulations.
This paper examines spatial variation in snow chemical composition and accumulation along a 200-km transect spanning the tundra-taiga transition near Inuvik, Northwest Territories. The study shows that ion loads vary up to 18-fold between mesoscale sites and demonstrate that both local landscape factors (vegetation roughness) and broad-scale influences (blowing snow, proximity to ocean) must be considered to predict snow quantity and chemistry in windswept Arctic environments.
This chapter examines the physical, chemical, and biological effects of diamond mining activities on riparian and terrestrial ecosystems, documenting impacts from exploration, construction, operation, and reclamation stages at diamond mines, with case studies from operations in Australia, Botswana, South Africa, Russia, and Guinea, and discussion of potential effects on northern Canadian ecosystems including permafrost, esker habitats, and wildlife migration corridors.
Executive summary of a comprehensive review of environmental effects of diamond mining on aquatic, riparian, and terrestrial ecosystems, identifying potential impacts including water contamination, habitat destruction, and soil degradation, while noting that mitigation effectiveness cannot be assessed without monitoring data from operating mines.
This document describes the methodological approach used to conduct a comprehensive literature review of the environmental effects of diamond mining worldwide, including strategies for acquiring both published information from 17 bibliographic databases and unpublished information through interviews and Internet forums.
The Coronation Impact Review Committee submits scoping phase comments on the BHP NWT Diamond Mine Environmental Impact Statement guidelines, addressing cumulative effects, consultation concerns, water quality monitoring of the Coppermine River, fish populations, Inuit traditional use and land claims, and archaeological impacts.
Submission SCP-050 — NWT Enviro Watch (Yellowknife, April 11 1995) to John Mathers, Panel Manager, BHP Diamond Mine Panel, faxed via FEARO Vancouver. NWT Enviro Watch comments on the BHP-DiaMet EIS Guidelines (similar to the April 11-12 1995 NWT Enviro Watch submission in batch 5). Includes News/North (April 10 1995, page A21) news clipping context.
NWT Enviro Watch comments to John Mathers, Panel Manager, BHP Diamond Mine Panel (April 11-12 1995, faxed via FEARO Vancouver). Provides organization comments on the BHP / DiaMet project description and EIS Guidelines, including BHP Mineral's DMS plant daily tonnage milled plot (1994-1995 Panda/Misery/Koala/Fox underground production projections — Leslie 1995 reference), citation of Canada Gazette Part II Vol 127 No 13 SOR/DORS/93-303 (Schedule V Licensing Criteria, Sections 5 and 8 — placer claims and waste disposal), and Misery Lake Pit tonnage curves.
Lorraine Catholique of Lutsel K'e First Nation presents concerns about non-renewable resource development in the North at an Ecology North public meeting on March 31, 1995, raising issues about First Nations benefits, environmental stewardship, cultural site protection, and advocating for sustainable renewable resource development as an alternative.
Lorraine Catholique of the Lutsel K'e First Nation presented concerns and hopes regarding non-renewable resource development in the North at an Ecology North public meeting, emphasizing the need for First Nations involvement in decision-making, environmental protection, equitable benefit-sharing, and sustainable development practices that respect Indigenous values and knowledge.
Mike Beauregard presents comments to the BHP Diamond Mine Environmental Review Panel addressing the scale of the proposed operation, health and safety concerns related to kimberlite mining (particularly serpentine dust and water control), and socio-environmental impacts of increased winter road traffic for mine operations.
Mike Beauregard presents scoping comments to the BHP Diamond Mine Environmental Review Panel, comparing the proposed operation's scale to Pine Point, advocating for health and safety protocols (dust and water control), and raising concerns about the ten-fold increase in winter road traffic and associated socio-environmental impacts.
Proceedings of the Tenth International Northern Research Basins Symposium and Workshop, Spitsbergen Norway, August 28 – September 3 1994. Organized by SINTEF Norwegian Hydrotechnical Laboratory and Norwegian Water Resources board. Includes H.G. Jones (INRS-Eau Ste-Foy), J.W. Pomeroy, T.D. Davies, M. Tranter, P. Marsh paper on aerosol and gaseous concentrations in ventilated dry Arctic snow covers — filter pack methodology for ions in snow vs ambient air, snow-atmosphere interface flow, enrichment factors, inter-grain ice ion transfer, and chemical composition of snow vs ambient air in sub-Arctic snowpacks.
This research paper examines the spatial distribution and relocation of major ions in seasonal snowcover along the tundra-taiga ecotone near Inuvik, Northwest Territories, demonstrating that ion concentrations vary significantly by landscape type due to snow redistribution, temperature-gradient metamorphism, aerosol deposition, and photochemical processes. The study shows that while sulfate scales linearly with snow accumulation, sea-salt and calcium ions are enriched through dry deposition and aerosol scavenging mechanisms, with nitrate undergoing vaporization loss, resulting in a useful landscape-stratification method for extrapolating Arctic snow chemistry measurements across larger regions.
A comprehensive research binder containing bibliographic references and materials organized into four tabs covering air quality studies, aquatic research, wildlife monitoring, and miscellaneous environmental topics related to the Ekati Diamond Mine region in the Northwest Territories.
This conference paper presents field experiments conducted in April 1992 near Inuvik, Canada, investigating net fluxes of nitrate and sulfate between arctic snow surfaces and the atmosphere, with particular focus on the influence of solar radiation. Results show solar radiation had no significant effect on NO3 and SO4 exchange, while sulfate exhibited dry deposition in the second experiment with a calculated deposition velocity of 0.09 cm s⁻¹.
United Nations Economic Commission for Europe report on post-project analysis (PPA) in environmental impact assessment, based on a task force led by Canada. The report analyzes 11 case studies from multiple countries to document approaches for using PPA to monitor project implementation, verify impact predictions, ensure compliance with conditions, and improve future EIA processes.
