Air Quality Monitoring Program, Ekati Diamond Mine (BHP Billiton, May 2012)
10 May 2012Report
This three-year Air Quality Monitoring Program report (2009-2011) for the EKATI Diamond Mine presents results from six monitoring components: meteorology, emissions calculations, ambient air quality monitoring (HVAS and CAM), dustfall, snow chemistry, and lichen tissue analysis. The report concludes that mining effects on air quality remain localized within approximately 1 km for heavier particles and 15 km for smaller particles, with values generally below relevant guidelines.

Long Lake Containment Facility Nitrate In Situ Treatment Test, EKATI Diamond Mine (BHP Billiton, April 2012)
1 April 2012Report
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.

Panda Diversion Channel Monitoring Program Final Report, Ekati Diamond Mine (BHP Billiton, March 2012)
1 March 2012Report
This is the final year (2011, 13th year) of monitoring the Panda Diversion Channel (PDC), a compensatory fish habitat constructed in 1997 to offset stream losses from Ekati Diamond Mine development. The report assesses the PDC's effectiveness through measurements of physical habitat (flow, temperature, water quality, culverts, enhancement structures), biological productivity (benthic invertebrates, vegetation, fish populations), and Arctic grayling use, concluding that the PDC has successfully matured and serves its purpose as defined in the 1996 Fish Habitat Compensation Agreement with Fisheries and Oceans Canada.

Wastewater and Processed Kimberlite Management Plan Version 2.0, EKATI Diamond Mine (BHP Billiton, October 2011)
20 October 2011Report
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.

Long Lake Containment Facility (LLCF) Nitrate In Situ Treatment Test, Ekati Diamond Mine (BHP Billiton, August 2011)
22 August 2011Letter
This report documents the 2010 Long Lake Containment Facility Nitrate In Situ Treatment Test, in which monopotassium phosphate fertilizer was applied to Cell D to stimulate phytoplankton growth and reduce nitrate concentrations. While Phase II (2009) achieved a 19% reduction in nitrate load, Phase III (2010) showed no statistically significant reduction despite residual phosphate benefits and a large early phytoplankton bloom, likely due to efficient zooplankton grazing that collapsed the bloom in late July.
