The Lutsel K'e Dene Band submits comments to the Environmental Assessment Panel regarding the BHP Diamond Mine Environmental Impact Study, expressing concerns about inadequate consultation, resource constraints, and lack of meaningful participation in the decision-making process for the proposed Lac de Gras project.
The NWT Chamber of Mines submits a letter supporting the adequacy of the Environmental Impact Statement for the proposed BHP NWT Diamonds Project, arguing it is comprehensive and comparing the project favorably to existing northern mining operations in terms of physical footprint, environmental impact, and economic benefits.
The Northern Environmental Coalition's comprehensive response to the BHP/Diamet Environmental Impact Statement for the proposed Ekati Diamond Mine identifies significant omissions and deficiencies across five major areas: biological impacts, cumulative effects, reclamation, socio-economic impacts, and traditional knowledge. The response critiques the EIS for inadequate treatment of wildlife management, water quality monitoring, fish habitat protection, and failure to conduct true cumulative effects assessment.
The Department of Fisheries and Oceans provides a conformity analysis and technical review of the Environmental Impact Statement for BHP Diamonds Inc.'s proposed NWT Diamonds Project in the Lac de Gras area. DFO identifies multiple deficiencies in baseline data, fish habitat assessment, and mitigation planning while concluding that public hearings can proceed, noting that 1995 field studies will address many information gaps.
The Dene Nation submits a letter of intervention on the BHP/Diamet diamond mine Environmental Impact Statement, identifying major deficiencies in both the review process and EIS content, including inadequate consultation with Dene communities, insufficient translation of technical documents, and failure to properly incorporate traditional knowledge in impact assessment.
The Department of Fisheries and Oceans provides a conformity analysis and technical review of BHP Diamonds Inc.'s Environmental Impact Statement for the proposed NWT Diamonds Project in the Lac de Gras area, identifying multiple deficiencies in baseline data, habitat assessment, and mitigation planning while recommending that public hearings may proceed pending resolution of the identified issues.
The Dene Nation submits formal comments on the BHP/Diamet diamond mine Environmental Impact Statement, raising concerns about the inadequate review process, insufficient consultation with Dene communities and Elders, deficient treatment of traditional knowledge, and incomplete technical documentation. The letter argues that the EIS does not provide sufficient information to assess environmental and socio-economic impacts and calls for greater involvement of Dene people in the assessment and decision-making process.
Natural Resources Canada's conformity review of BHP Diamonds Inc.'s Environmental Impact Statement for the proposed NWT Diamonds Project, identifying deficiencies primarily related to permafrost and ground ice effects on mine design, tailings stability, reclamation feasibility, and economic impact analysis. The review concludes the EIS is partially conforming and sufficient to proceed to hearings despite identified minor deficiencies.
Natural Resources Canada's conformity review of the Environmental Impact Statement for BHP Diamonds Inc.'s NWT Diamonds Project identifies partial conformity to guidelines, with deficiencies primarily related to permafrost and ground ice effects on tailings stability, reclamation feasibility, and long-term environmental impacts. The review concludes the EIS is sufficient to proceed to hearings but recommends addressing gaps in understanding of permafrost behavior, availability of reclamation materials, contingency planning, and monitoring protocols.
The Canadian Coast Guard identifies deficiencies in the BHP Environmental Impact Statement for the NWT Diamond Mines Project, requiring formal approval under the Navigable Waters Protection Act due to substantial interference with navigable waters through proposed dams, water diversions, and dewatering of multiple lakes.
The Canadian Coast Guard identifies deficiencies in the BHP Environmental Impact Statement for the NWT Diamond Mines Project regarding compliance with the Navigable Waters Protection Act, specifically detailing inadequate descriptions of water level impacts, lake profiles, dam specifications, and the navigability of affected waterways including Panda, Kodiak, Koala, Misery, Fox, Leslie, Long Lakes and Lac De Gras.
This geotechnical report characterizes the properties of New Fox and Panda kimberlite tailings from a proposed diamond mine in the Northwest Territories, including solids content, grain size distribution, consolidation behavior, hydraulic conductivity, and filtration performance. The study concludes that New Fox tailings are more problematic for disposal than Panda tailings due to finer particle sizes, lower water release rates, and higher turbidity potential.
Response by Ecology North and the Northern Environmental Coalition (NEC) to the BHP / DiaMet Environmental Impact Statement, October 23 1995 (26 pages, transmitted via World Wildlife Fund / WWF). Identifies deficiencies in the EIS regarding the ecosystem approach, esker mining for road material and esker rehabilitation, lemmings and voles, land claims and Aboriginal self-government, and the omission of cumulative environmental impacts of the proposed BHP NWT diamond mine.
DIAND's conformity and quality analysis of BHP Diamonds Inc.'s Environmental Impact Statement for the proposed NWT Diamonds Project, submitted July 1995, concluding that while the EIS substantially addresses guideline information requirements, significant deficiencies exist in terrain and permafrost characterization, waste management planning, water management rationale, traditional knowledge integration, monitoring programs (particularly post-closure), and cumulative effects assessment.
Curriculum vitae of Peter James McCart, a fisheries scientist and biological consultant with extensive expertise in aquatic ecosystem assessment, fish population studies, and environmental impact analysis across Arctic and sub-Arctic regions. The document details his education, 40+ years of career experience with major energy and development projects, expert testimony, scientific publications, and comprehensive company reports on fish and aquatic habitat impacts from pipeline, mining, and hydroelectric projects.
BHP responds to a Panel request regarding corporate experience with spills and accidents, documenting ten unauthorized discharges at the Koala site from October 1993 to April 1995, including detailed descriptions of causes, response actions, environmental monitoring results, and long-term mitigative measures at Phase I and II tailings impoundments and Fox minewater settling pond facilities.
The Northwest Territories Water Board issued this mining exploration and development questionnaire in August 1995 to solicit supplemental information from applicants for water licence applications or renewals. The questionnaire covers geological characteristics, exploration operations, milling processes, containment areas, water treatment, environmental monitoring, and environmental assessment requirements under the Canadian Environmental Assessment Act.
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.
A comprehensive environmental effects review of diamond mining operations prepared for Environment Canada, examining the physical, chemical, and biological impacts of diamond mining activities on aquatic, riparian, and terrestrial ecosystems across exploration, construction, operation, and reclamation phases.
This document presents conclusions and recommendations from a review of environmental effects of diamond mining on aquatic, riparian, and terrestrial ecosystems. It identifies significant potential effects from mining activities and recommends additional research, toxicity testing, environmental monitoring, and data collection from operating mines in northern climates to better understand and mitigate these impacts.
