Conformity Review of the Environmental Impact Statement, NWT Diamonds Project (Natural Resources Canada, October 1995)
19 October 1995Regulatory Filing
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.

Conformity Review of the BHP NWT Diamonds Project Environmental Impact Statement (Natural Resources Canada, October 1995)
19 October 1995Regulatory Filing
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.

Comments on Deficiencies in the BHP Environmental Impact Statement, NWT Diamond Mines Project (Canadian Coast Guard, October 1995)
17 October 1995Letter
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.

Geotechnical Properties of New Fox and Panda Tailings Report, Appendix A (University of Alberta, October 1995)
12 October 1995Report
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 to BHP, DiaMet Environmental Impact Statement (Northern Environmental Coalition (NEC), October 1995)
1995Regulatory Filing
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.

Conformity and Quality Analysis, BHP Diamonds Inc. Environmental Impact Statement, NWT Diamonds Project (DIAND, October 1995)
1 October 1995Regulatory Filing
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.

Mining Exploration and Development Questionnaire for Water Licence Applications (NWT Water Board, August 1995)
1 August 1995Unknown / Unclassified
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.

Spatial Distribution of Snow Chemical Load at the Tundra Taiga Transition (Pomeroy & Marsh, July 1995)
1 July 1995Report
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.
