BHP Billiton's EKATI Diamond Mine Summer 2012 newsletter highlights operational achievements including safety milestones at the Misery project expansion, community investments in heritage centres and literacy programs, recognition of employee contributions, and partnerships with educational and charitable organizations across the Northwest Territories.
This report documents the 2011 Phase IV nitrate in situ treatment test at the Long Lake Containment Facility (LLCF) of the EKATI Diamond Mine, in which monopotassium phosphate fertilizer (4.3 tonnes) was added to Cell D between July 29 and August 20 to stimulate phytoplankton growth and biological uptake of elevated nitrate concentrations. Although the test stimulated phytoplankton blooms, there was no significant reduction in the calculated nitrate load of Cell D over the 2011 open-water season; however, nitrate concentrations did not increase despite continued upstream loading.
Agenda — BHP Billiton Canada Inc. Environmental Impact Report (EIR) Technical Session for the EKATI Diamond Mine, Katimavik Room, Explorer Hotel, July 9-11 2012. Day 1 covers Completion of the Panda Diversion Channel (PDC) Monitoring Program (constructed 1997 as compensation for stream-habitat loss, 10-year monitoring) by François Landry (Rescan Environmental Services Ltd.) — comparison to Pigeon and Polar-Vulture Streams reference systems. Day 2 covers EIR Technical Session including the Effluent Discharge Plan to restore Long Lake Containment Facility (LLCF) Emergency Storage Capacity through winter/spring (within allowable flow rates) and EKATI Site-Specific Water Quality Objective (SSWQO) for Nitrate.
BHP Billiton's 2011 Year in Review for EKATI Diamond Mine reports on operational achievements including 3 million carats of rough diamond production, 1,213 person-years of employment (650 for Northerners and Northern Aboriginals), C$327 million in spending, and major community investments in education and women's housing; the document also highlights safety excellence, environmental stewardship through ISO certifications, and extensive Traditional Knowledge preservation projects with Impact Benefit Agreement partners.
BHP Billiton's Wastewater and Processed Kimberlite Management Plan Version 2.0 (October 2011) describes the comprehensive management strategy for all wastewater and fine processed kimberlite at the Ekati Diamond Mine, submitted to the Wek'èezhii Land and Water Board for approval under Water Licence W2009L2-0001. The plan proposes significant updates to processed kimberlite deposition strategy, deferring or potentially eliminating the need for Cell D deposition by utilizing upstream areas in Cells A and C and the mined-out Beartooth Pit, while maintaining water quality standards and minimizing environmental effects in the receiving environment.
A draft five-year Barren-ground Caribou Management Strategy (2011-2015) for the Northwest Territories, building on the 2006-2010 strategy to guide actions helping caribou herds increase through five key components: engaging partners, collecting information for management, managing factors influencing caribou trends, public education, and maximizing benefits, requiring $19.1 million in total investment.
This is the 2011 Environmental Agreement and Water Licence Annual Report Summary for the EKATI Diamond Mine in the Northwest Territories, documenting BHP Billiton's compliance with regulatory requirements and monitoring results across air quality, water quality, land reclamation, fish habitat, and wildlife populations.
This report documents a two-phase nitrate in situ treatment test conducted at the Long Lake Containment Facility (LLCF) at the Ekati Diamond Mine during 2008-2009, where phosphorus fertilizer additions stimulated phytoplankton growth to reduce elevated nitrate concentrations in minewater. Phase II (2009) added 16 tonnes of monopotassium phosphate to Cell D, achieving a 19% reduction in nitrate load while maintaining containment and monitoring potential secondary effects in downstream waters.
BHP Billiton's 2009 Year in Review reports on Ekati Diamond Mine's operations, highlighting safety improvements with a 47% decrease in injury rates, employment of over 2,000 people with 59% Northern participation, $268 million in spending (67% with Northern businesses), and community investments exceeding $2.9 million. The report also documents environmental management initiatives, production achievements, and progress on future mining projects.
